Your ONLY modification\n    is to fix spelling, punctuation, and grammar. If the input is a question,\n    convert it into a declarative claim.\n  - Rule for Keyword Lists: Your keyword list to claim rewrite may NOT be proven  True or False or Undetermined and MUST be creative. You MUST NOT summarize the keywords. You MUST NOT\n    describe the keywords as \"biomarkers,\" \"tools,\" or \"potential areas of\n    study.\" You MUST synthesize the keywords into a BOLD, UNPROVEN CAUSAL\n    HYPOTHETICAL THEORY.\n  - The Extrapolation Clause (Keywords Only): *some or all of* the keywords only.  novel idea. \n\n2. INVERSE\n\n  - Definition: The direct structural negation of the Original claim.\n  - Rule: Directly negate the primary relationship. Do NOT introduce new\n    variables. Flip the boolean state of the primary verb (e.g., \"promotes\"\n    becomes \"does not promote\").\n\n3. ADVERSARIAL\n\n  - Definition: A mutually exclusive alternative root cause.\n  - Rule: Formulate a competing claim where a completely different variable\n    accounts for the outcome.\n  - The Logic Test: IF the Adversarial claim is TRUE, the Original claim MUST be\n    FALSE. It must represent a conflict of causality.\n\n4. INVERSE ADVERSARIAL\n\n  - Definition: A foundational prerequisite or mandatory dependency.\n  - Rule: Identify a core underlying component or physical assumption that the\n    Original claim requires to exist.\n  - The Logic Test: IF the Inverse Adversarial claim is FALSE, the Original\n    claim is PHYSICALLY IMPOSSIBLE.\n\nOUTPUT FORMAT\n\nReturn ONLY valid JSON. Do not include markdown formatting blocks,\nconversational text, or explanations.\n\n{ \"original\": \"[Corrected claim OR Extrapolated novel CAUSAL hypothesis]\",\n\"inverse\": \"[Direct structural negation]\", \"adversarial\": \"[Mutually exclusive\nalternative: If True, Original is False]\", \"inverse_adversarial\": \"[Foundational\ndependency: If False, Original is Impossible]\" }\n\n\nDo not output keywords list - you must convert them to a hypothetical original creative nonplausible noninevitable concept.

USE \"OR\" for edge discovery.\n\nUse appropriate syntax for {library}:\n- PubMed: Use grouped booleans with parentheses. Group synonyms using OR (e.g., (\"Term 1\" OR \"Synonym 1\")). Connect distinct core concepts using AND. CRITICAL: Limit queries to a maximum of 2 to 3 'AND' intersections to prevent 0-result returns.

Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression.

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total).

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current.

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

The physicochemical properties of the FCPs were then characterized, and the anti-aging effects of FCPs were evaluated in Caenorhabditis elegans (C. elegans). It was demonstrated that FCPs significantly extended the lifespan of the nematodes, while improving locomotor activity without affecting the body size or reproductive capacity. Meanwhile, FCPs reduced lipofuscin accumulation, decreased intracellular reactive oxygen species (ROS) levels, and increased the survival of C. elegans under oxidative stress. Moreover, FCPs upregulated the expression of antioxidant genes sod-1, sod-3, ctl-2, ctl-3 and gst-4. The expression of skinhead-1 (skn-1), a homologue gene of mammalian nuclear factor erythroid 2-related factor (Nrf) in C. elegans, was also elevated upon FCPs treatment. Knockdown of skn-1 expression by RNA interference abolished the lifespan extension and ROS reduction in FCPs-treated C. elegans, indicating that the SKN-1-mediated signaling was essential for the anti-aging effects of FCPs. Additionally, FCPs caused downregulation of the key components of the insulin/IGF-1 signaling (IIS) pathway, age-1, akt-1, and akt-2. Overall, these results suggested that FCPs promoted longevity in C. elegans via modulation of SKN-1 and IIS pathway."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression.

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total).

The P66R mutation in SOD1 destabilizes local structure and promotes \u03b2-sheet-driven fibrillation, which makes it a suitable model for exploring approaches for reducing pathogenic aggregation. Here, we evaluate silymarin, a polyphenolic compound with known antioxidant and neuroprotective properties, for its potential to inhibit P66R-hSOD1 aggregation. ThT fluorescence and transmission electron microscopy analyses demonstrate a significant decrease in amyloid fibril formation in the presence of silymarin; in addition, FTIR spectroscopy confirms the suppression of \u03b2-sheet formation. Fluorescence quenching and ANS binding assays indicate a moderate-affinity binding between silymarin and the mutant protein, along with a reduction in surface hydrophobicity. Hemolysis assays confirm its protective effect against membrane damage induced by aggregates, while molecular docking and dynamic simulations indicate that silymarin stabilizes aggregation-prone areas with hydrogen bonding and hydrophobic interactions, thereby promoting compact conformations and reducing solvent-exposed surfaces. The findings identified silymarin as an effective anti-amyloidogenic agent that reduces \u03b2-sheet accumulation and fibril formation while also decreasing cytotoxicity, highlighting its potential as a therapeutic candidate for ALS."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total).

Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study.

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models.

The P66R mutation in SOD1 destabilizes local structure and promotes \u03b2-sheet-driven fibrillation, which makes it a suitable model for exploring approaches for reducing pathogenic aggregation. Here, we evaluate silymarin, a polyphenolic compound with known antioxidant and neuroprotective properties, for its potential to inhibit P66R-hSOD1 aggregation. ThT fluorescence and transmission electron microscopy analyses demonstrate a significant decrease in amyloid fibril formation in the presence of silymarin; in addition, FTIR spectroscopy confirms the suppression of \u03b2-sheet formation. Fluorescence quenching and ANS binding assays indicate a moderate-affinity binding between silymarin and the mutant protein, along with a reduction in surface hydrophobicity. Hemolysis assays confirm its protective effect against membrane damage induced by aggregates, while molecular docking and dynamic simulations indicate that silymarin stabilizes aggregation-prone areas with hydrogen bonding and hydrophobic interactions, thereby promoting compact conformations and reducing solvent-exposed surfaces. The findings identified silymarin as an effective anti-amyloidogenic agent that reduces \u03b2-sheet accumulation and fibril formation while also decreasing cytotoxicity, highlighting its potential as a therapeutic candidate for ALS."

Here, we present SKALE 2.0, a phase-resolved geometric deep learning framework that represents proteins as multimodal structural graphs and learns mutation-induced aggregation phenotypes directly from three-dimensional topology. Across SOD1, TDP-43, MAPT, and PRNP, SKALE 2.0 recovered a conserved latent transition from nucleation to elongation while resolving distinct mutation-specific phase sensitivities. Representative protein language model, AlphaFold-derived feature, and non-phase-aware structural baselines failed to recover both phase-dependent mutation modulation and phase separability, indicating that explicit phase conditioning is essential. The learned geometry showed that nucleation is preferentially coupled to buried hydrophobic perturbations, whereas elongation is shaped by solvent-accessible interfaces that support fibril propagation. This framework explains how pathogenic variants can remain globally folded yet acquire aggregation competence through localized structural rewiring. Recombinant SOD1 experiments validated predicted suppressor, enhancer, and phase-switch mutations, demonstrating that initiation and propagation can be tuned independently. SKALE 2.0 links atomic topology to phase-specific assembly kinetics and enables a constraint-aware design of aggregation suppressors."

Several recent genetic studies have found disease-causing variants in 50%-85% of patients with fALS and 10%-15% of those with sALS. The aim of our study is to review our clinical experience with sponsored genetic testing (i.e., pharmaceutical company-sponsored and cost-free to patient) since its inception. We reviewed the medical records on all ALS patients seen at our Center who consented to sponsored genetic testing from August 2021 through October 2025. Of the 170 medical records reviewed, 22 patients (12.9%) tested positive for a disease-causing variant in a known autosomal dominant disorder. Thirteen of 35 patients with fALS (37.1%) were found to have a disease-causing variant, in contrast to 9 of 135 patients (6.7%) with sALS. Of the 22 disease-causing variants found, the following genes were involved in decreasing frequency: C9orf72 11 (50%), SOD1 6 (27.3%), FUS 2 (9.1%), and one each (4.5%) of SQSTM1, TARDBP, and TBK1. Twenty-eight patients (16.5%) harbored 29 variants of uncertain significance (VUS). Results of testing led to medically actionable activities including genetic counseling for patients and at-risk family members with positive results, and treatment (i.e., intrathecal tofersen) for the two patients harboring pathogenic SOD1 variants. The lower diagnostic yields than previously published for fALS and sALS patients likely are related to lower numbers of genes tested in the sponsored genetic panels, and these are expected to improve as more genes are added."

Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease."

Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration."

The mechanisms regulating TDP43 solubility remain incompletely understood. Here, we report that TDP43 undergoes S-acylation primarily at the Cys244 residue by the S-acyltransferase zDHHC23. This S-acylation maintains the liquid-like properties of TDP43 by reducing the aberrant interaction with poly(ADP-ribose) polymerase 1 (PARP1) and PARylated proteins, thereby countering the pathological condensation of TDP43. S-acylation-deficient TDP43 inclusions sequester the translational machinery and inhibit cytoplasmic protein translation, ultimately resulting in neurotoxicity. Importantly, TDP43 S-acylation is decreased in the familial ALS-associated TDP43 mutants as well as in SOD1-G93A mice and C9orf72-ALS induced pluripotent stem cell (iPSC)-derived neurons, suggesting the widespread involvement of TDP43 S-acylation in ALS pathogenesis.

We examined synaptic plasticity, the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses, dendritic spine morphology, and the putative excitatory/inhibitory (E/I) ratio in the B2 barrel of the somatosensory cortex in female mice of an ALS mouse model. Transgenic mice, B6SJL-Tg (SOD1*G93A)1Gur/J, were used as the ALS model, and wild-type (WT) B6SJL/F1 mice served as controls. ALS mice were allocated to experimental groups based on disease stage (pre-symptomatic, onset, or terminal) and training condition (swim-trained or untrained). Swim training was applied after the first onset of symptoms (clinical score 1). We analyzed and quantified the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses and E/I ratios using serial electron micrographs to understand how these parameters change during disease progression and whether swim training influences this process. Our results showed stage-dependent alterations in asymmetric (putative excitatory) and symmetric (putative inhibitory) synaptic architecture in ALS. The obtained data showed an increase in the excitatory synaptic density in the presymptomatic ALS mice. This finding is consistent with previous reports of early cortical hyperexcitability and may reflect structural alterations associated with an initial increase in excitatory synapses before disease onset. Importantly, we report here an increase in inhibitory synapses at disease onset. TEM-based synaptic density quantification revealed reduced excitatory synapse density in the B2 barrel of the somatosensory cortex of trained ALS mice compared to WT controls, alongside a trend toward a reduced putative excitatory/inhibitory synaptic ratio. However, as no significant differences were detected between trained and untrained ALS mice, the contribution of swim training to these alterations remains unclear. Notably, swim training was not associated with detectable adverse effects on somatosensory cortex ultrastructure, excitatory synapse density, or the putative excitatory/inhibitory ratio, supporting previous observations that swim training is well tolerated under these experimental conditions. To our knowledge, these results provide the first TEM-based ultrastructural characterization of synaptic architecture in swim-trained SOD1-G93A mice, although further studies are needed to establish the underlying mechanisms and therapeutic relevance in ALS."

On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression.

We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression. These findings suggest that longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS."

Integrating scientific research with clinical informatics into clinical practice facilitates novel methodologies for patient care. Computational pathology is a burgeoning subspecialty in pathology that promises a better-integrated solution to histopathological images and clinical informatics. Deep-learning methods in computational pathology have demonstrated considerable advances in automated histopathological image analysis. However, convolutional neural networks (CNNs) face fundamental limitations when dealing with the significant morphological heterogeneity present in disease tissues. Conventional CNNs use fixed convolutional kernels, which restrict their effectiveness in adaptively extracting features from histopathological images that exhibit diverse pathological patterns, staining intensities, and tissue architecture. To address this substantial limitation, we present an optimized variant of Omni-Dimensional Dynamic Convolution (ODConv) networks for distinguishing diseased tissue from healthy tissue. Compared with prior dynamic convolution methods that attend to a single kernel dimension, ODConv applies multi-dimensional attention across spatial positions, input channels, output channels, and kernel candidates, enabling more flexible and adaptive feature extraction. We evaluated our approach on wheat-germ agglutinin-stained and hematoxylin and eosin-stained skeletal muscle images from multiple disease models, including G93A*SOD1 transgenic mice (amyotrophic lateral sclerosis) and Akita mice (Type I diabetes). ODConv, trained entirely from scratch without ImageNet pretraining, achieved competitive classification performance relative to seven fine-tuned pretrained architectures across both staining modalities, demonstrating the effectiveness of omni-dimensional dynamic kernels in learning discriminative morphological representations directly from domain data. The study reports strong statistical agreement metrics, proving effective class balance handling and stable decision boundaries. These findings confirm ODConv as a strong computational pathology framework that advances automated diagnosis of neurodegenerative and metabolic skeletal muscle disorders."

Prion-like propagation of misfolding is an attractive therapeutic target, but difficulties with assaying conversion directly and simply have severely limited efforts to find drugs targeting conversion of disease-related proteins.

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

This necessitates the development of a methodology that can characterize the conformational states related to protein unfolding and thus allow for the investigation of the molecular mechanism responsible for disease progression. Here, we demonstrate how temperature-controlled nanoelectrospray ionization (TC-nESI) combined with high-resolution ion mobility-mass spectrometry (IM-MS), surface-induced dissociation (SID), and limited proteolysis can be used to define the misfolding and oligomerization landscape of bovine Cu/Zn superoxide dismutase (SOD1). This integrative approach enables real-time detection of coexisting intermediates, and captures molecular events including metal-induced stability, monomer unfolding and assembly into heterogeneous soluble oligomers. Our results reveal that both holo- and apo-SOD1 undergo dimer dissociation followed by monomer misfolding and assembly into heterogeneous non-native oligomers, and that slow thermal ramping promotes the accumulation of misfolded monomers and higher-order complexes. Apo-SOD1 that lacks stabilizing metal cofactors, forms more compact and kinetically distinct oligomers via monomeric, dimeric and trimeric intermediates. Proteolysis and heat-induced fragmentation identify loops V, VI, VII, and the C-terminus as key labile regions contributing to oligomer interface formation, predominantly through hydrophobic interactions. Our findings establish a mechanistically rich model for early aggregation and demonstrate the capability of TC-nESI-IM-MS to temporally and structurally resolve misfolding transitions and oligomeric populations in a single experiment. This platform provides a framework to dissect oligomerization pathways relevant to neurodegenerative diseases."

Genes such as ACE, SOD1 and PER3 play important roles in regulating essential biological functions. These genes are involved in key physiological pathways, including blood pressure regulation, oxidative stress response and circadian rhythm maintenance, and genetic variants within them may influence susceptibility to cancer. Therefore, this study investigates the association between polymorphisms in the ACE, SOD1 and PER3 genes and the risk of breast cancer, with the aim of evaluating how these genetic variations relate to breast cancer susceptibility and clinical outcomes in Jordanian women. Blood samples of 300 women diagnosed with breast cancer, along with 300 healthy participants, were collected, and DNA was extracted from them. Genetic variants in the ACE (rs1799752), SOD1 (rs36232792) and PER3 (rs57875989) genes are examined through employing direct PCR to amplify the target regions. The ACE (rs1799752) variant was observed to be associated with breast cancer susceptibility, with the I/I genotype increasing risk of breast cancer (OR = 5.138, 95% CI = 1.38-19.03, p = 0.014). No associations were observed for SOD1 (rs36232792) and PER3 (rs57875989) variants. The rs1799752 polymorphism is suggested to have the potential of serving as a biomarker for breast cancer susceptibility in Jordanian women, as it is associated with elevating the risk."

While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS."

However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system."

Although BAFF is a well-known protein in B-cell functions, its role in bronchial cell function remains undefined. Polyinosinic-polycytidylic acid (Poly (I:C)), a synthetic double-stranded RNA, serves as a model for viral infection that binds to toll-like receptor (TLR) 3 to trigger intracellular signal pathways. In this study, we investigated the effect of Poly (I:C)-induced BAFF expression on airway cell migration using Beas-2B human bronchial epithelial cells. Poly (I:C) increased BAFF expression and cell migration, along with the increased expression of N-cadherin, Vimentin and Slug (SNAI2), which are three primary markers for epithelial-mesenchymal transition (EMT). Cell migration was attenuated by small interfering RNA (siRNA) against BAFF, which also inhibited the expression of these EMT markers. Phosphorylation of c-Jun N-terminal kinase (JNK) was enhanced by Poly (I:C) and inhibited by SP600125, JNK inhibitor, leading to a decreased expression of BAFF and aforementioned EMT markers. Poly (I:C) increased reactive oxygen species (ROS), resulting in a ROS-dependent up-regulation of antioxidants (Catalase, superoxide dismutase (SOD)1 and heme oxygenase (HMOX)1) and Nrf2. Pre-treatment with N-acetylcysteine (NAC), ROS scavenger, inhibited Nrf2 activation and JNK phosphorylation. The increase in Nrf2 levels induced by Poly (I:C) was also attenuated by SP600125. Additionally, while NAC treatment inhibited BAFF expression, it caused little change in the expression of the three EMT markers. Increased BAFF expression was confirmed by Nrf2 binding to the BAFF promoter or an increase in the luciferase activity of BAFF promoter co-transfected with Nrf2 plasmids. Treatment with recombinant BAFF protein also increased cell migration and EMT marker expression. Taken together, our results demonstrate that Poly (I:C) promotes a regenerative migration of bronchial epithelial cells by inducing BAFF expression through the ROS-dependent JNK-Nrf2 signaling axis."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)).

Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen).

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot."

This work studies the metabolic effects of elevated phosphate on muscle. C2C12 cells were differentiated in the absence or presence of 10 mM \u03b2-glycerophosphate (BGP), an exogenous phosphate donor. In addition, quadriceps muscles from four experimental groups of male C57BL/6J mice were analyzed: young (5 months) and old (24 months) fed with standard diet; old mice fed with hypophosphatemic diet or supplemented with the phosphate binder Velphoro\u00ae, for the last three months of life. Mice were stratified according to sarcopenia degree based on muscle mass, strength and physical performance. Protein levels were determined by immunoblotting and mRNA expression by RT-qPCR. ATP levels were measured by luminescence and L-lactate production, citrate synthase and cytochrome c oxidase activities by colorimetric assays. Mitochondrial content, membrane potential and reactive oxygen species (ROS) were determined by fluorescence assay. BGP-treated cells showed increased glucose transporter 1 (GLUT1) and decreased NADH Dehydrogenase (CI-NDUFB8) protein expression, elevated hexokinase II (HK2), phosphoglycerate kinase 1 (PGK1) and lactate dehydrogenase A (LDHA) mRNA levels, reduced ATP levels, increased lactate production, and decreased mitochondrial enzyme activities. Moreover, BGP increased ROS, diminished mitochondrial membrane potential, and altered fusion-fission dynamics and mitophagy. In aged quadriceps, oxidative phosphorylation (OXPHOS) subunits and superoxide dismutase 2 (SOD2) expression were reduced. The hypophosphatemic diet improved all parameters, whereas Velphoro\u00ae selectively increased Mitochondrial cytochrome C oxidase subunit 1 (CIV-MTCO1) expression. Several altered mitochondrial markers are associated with sarcopenia degree. Altogether, hyperphosphatemia induces metabolic changes that scale with the sarcopenic degree. Our findings show a relevant association between hyperphosphatemia and mitochondrial dysfunction, and they support the potential benefit of phosphate reduction as a strategy to prevent or mitigate sarcopenia."

However, studies investigating the toxic effects of Cd on crucian carp (Carassius auratus) are relatively few. This study aimed to evaluate the toxic effects of Cd by assessing hematological parameters, antioxidant responses, and the expression of stress-related genes in C.\u00a0auratus exposed to waterborne Cd. A total of 180 healthy C.\u00a0auratus (19.43 \u00b1\u00a01.5 cm and 170.00 \u00b1\u00a03.04 g) were exposed to Cd at concentrations of 0, 2, and 4 mg/L for 8 weeks, with three replicates per treatment. The exposure to Cd resulted in significant reductions in red blood cell (RBC) count, hemoglobin (Hb) concentration, and hematocrit (Hct) values. Moreover, the levels of total superoxide dismutase (T-SOD), catalase (CAT), and glutathione peroxidase (GPx) in the liver also decreased significantly, whereas malondialdehyde (MDA) content was increased significantly. The expression levels of CAT, copper (Cu)/zinc (Zn)-superoxide dismutase (Cu/Zn-SOD), heat shock protein 70 (HSP70), heat shock protein 90 (HSP90), and metallothionein (MT2) genes were significantly upregulated. Overall, Cd exposure adversely affected the hematological parameters, induced oxidative stress, and altered the expression levels of stress-related genes. This study not only provides new insights into the toxic effects of Cd in C. auratus but also contributes to environmental monitoring research."

However, the extent to which microbial indicators of dysbiosis covary with host oxidative stress and epithelial apoptotic responses during pregnancy remains unclear. In this analytical cross-sectional study, 220 pregnant women were screened at a referral gynecology clinic in Faisalabad, Pakistan; 168 met the eligibility criteria and had concordant modified Amsel and Nugent classifications (56 BV-positive, 112 BV-negative). Cervicovaginal secretions, vaginal swabs, and serum were analyzed for microbial, oxidative stress, and host-response markers. Epithelial-enriched cervicovaginal specimens passing predefined quality criteria (n\u202f=\u202f142) were used for apoptosis-related gene expression and caspase-3/7 activity assays. Targeted microbial quantification focused on Lactobacillus and Acinetobacter spp. Associations between bacterial burden and host markers were evaluated using correlation and regression analyses with the Benjamini-Hochberg false-discovery-rate correction, where applicable. BV-positive participants exhibited a lower Lactobacillus spp. burden and a higher Acinetobacter spp., burden than BV-negative controls. They also showed higher cervicovaginal malondialdehyde and H2O2 concentrations and lower superoxide dismutase and catalase activities (all FDR-adjusted q\u202f<\u202f10-13). Epithelial-enriched specimens from BV-positive participants demonstrated a higher BAX/BCL2 ratio, increased caspase-3/7 activity, increased expression of BAX, CASP9, CASP3, SOD2, and HMOX1, and reduced BCL2 expression. Higher Acinetobacter spp. burden covaried with greater local oxidative stress and increased epithelial apoptosis-associated signaling, although these associations were attenuated after adjustment for BV status. BV in pregnancy was associated with concurrent differences in cervicovaginal microbial indicators, oxidative stress, and epithelial apoptosis-related responses, supporting an integrated host-microbe response at the cervicovaginal interface. These findings provide a foundation for future longitudinal and mechanistic studies investigating host-microbe interactions in pregnancy-associated BV."

Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total).

Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study.

Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot."

Several altered mitochondrial markers are associated with sarcopenia degree. Altogether, hyperphosphatemia induces metabolic changes that scale with the sarcopenic degree. Our findings show a relevant association between hyperphosphatemia and mitochondrial dysfunction, and they support the potential benefit of phosphate reduction as a strategy to prevent or mitigate sarcopenia."

However, studies investigating the toxic effects of Cd on crucian carp (Carassius auratus) are relatively few. This study aimed to evaluate the toxic effects of Cd by assessing hematological parameters, antioxidant responses, and the expression of stress-related genes in C.\u00a0auratus exposed to waterborne Cd. A total of 180 healthy C.\u00a0auratus (19.43 \u00b1\u00a01.5 cm and 170.00 \u00b1\u00a03.04 g) were exposed to Cd at concentrations of 0, 2, and 4 mg/L for 8 weeks, with three replicates per treatment. The exposure to Cd resulted in significant reductions in red blood cell (RBC) count, hemoglobin (Hb) concentration, and hematocrit (Hct) values. Moreover, the levels of total superoxide dismutase (T-SOD), catalase (CAT), and glutathione peroxidase (GPx) in the liver also decreased significantly, whereas malondialdehyde (MDA) content was increased significantly. The expression levels of CAT, copper (Cu)/zinc (Zn)-superoxide dismutase (Cu/Zn-SOD), heat shock protein 70 (HSP70), heat shock protein 90 (HSP90), and metallothionein (MT2) genes were significantly upregulated. Overall, Cd exposure adversely affected the hematological parameters, induced oxidative stress, and altered the expression levels of stress-related genes. This study not only provides new insights into the toxic effects of Cd in C. auratus but also contributes to environmental monitoring research."

Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers."

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)).

However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses."

Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement.

In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria.

Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement. Reprogramming central-peripheral immune crosstalk with PBM resolves neuroinflammation and restores cognition in AD models-a translatable strategy for combating neurodegeneration."

However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses."

In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain."

There is increasing evidence linking ASD with an altered composition of the gut microbiota and chronic low-grade inflammation, suggesting a key role of the gut-brain axis (GBA) in the pathophysiological development of this condition. This mini review explores the molecular and immunological mechanisms underlying the associations between ASD and gut dysbiosis, with particular emphasis on the therapeutic potential of fecal microbiota transplantation (FMT). Dysbiosis can compromise the integrity of the intestinal barrier, increasing permeability and the translocation of pathogen-associated molecular patterns (PAMPs), such as lipopolysaccharides (LPS), thereby releasing inflammatory cytokines, including IL-6 and TNF-\u03b1. These mediators activate the mucosal immune pathways, such as the NF-\u03baB signaling and NLRP3 inflammasome, thereby contributing to neuroinflammation and elevating intestinal biomarker levels, such as S100B, RANTES, and calprotectin. Emerging evidence suggests that FMT may restore microbial diversity, promote the expansion of beneficial short-chain-fatty-acid-producing taxa, and reinforce intestinal tight junction proteins, thereby improving the integrity of the gut barrier. These effects may attenuate systemic inflammation, modulate central immune responses, regulate neurotransmitter levels, and improve gastrointestinal and behavioral outcomes in individuals with ASD. Despite these promising findings, current evidence remains limited by small sample sizes, methodological heterogeneity, and short follow-up periods. Hence, future research efforts should prioritize well-designed randomized controlled trials and the development of personalized microbial-based interventions to establish FMT as a safe and effective therapeutic strategy for ASD."

Despite substantial progress in biomarker discovery, numerous challenges persist in the accurate diagnosis and prognosis of pediatric epilepsy. Glycosylation is known to play a critical role in neuronal function and neuroinflammation, but the differential glycome profile associated with the onset and progression of pediatric epilepsy has not been investigated. This study investigates the alterations in N-glycan signatures present in plasma and cerebrospinal fluid (CSF) from individuals experiencing focal and generalized epilepsy and developmental and epileptic encephalopathies (DEE). Discriminative models demonstrate distinct N-glycome profiles in both plasma and CSF that effectively differentiate between control subjects and those with epilepsy, identifying a specific set of 11 N-glycans common to both biological fluids. Notably, we observed a significant elevation in mannosylation and mono-sialylation of CSF in cases of DEE. High mannosylated and mono-sialylated N-glycans exhibited strong diagnostic potential for DEE. The biosynthetic network of CSF N-glycans indicated that sialylation, galactosylation, and bisection are the primary contributors to the transition from controls to DEE. Furthermore, the abundance of sialylation, fucosylation, and bisection correlated positively with the levels of proteins and sugars in CSF. These findings identify N-glycosylation changes in CSF as biosignatures associated with pediatric epilepsy, especially DEE, and support further evaluation of glycoprotein N-glycome profiling for disease classification and clinical stratification."

However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097."

Numerous studies have shown that Huashi Baidu formula (HBF) may exert a satisfactory effect on myocardial function repair. This study aims to reveal the underlying mechanisms and main bioactive compounds (BACs) of HBF against myocardial injury. Firstly, this study established an ADR-induced mouse model to assess the protective effects of HBF against myocardial injury. Subsequently, transcriptomic profiling was conducted to screen the differentially expressed genes among the HBF treatment, ADR-induced model, and normal control groups. Following the construction and analysis of protein-protein interactions, gene set enrichment analysis, and co-expression matrix, the key targets of HBF against myocardial injury were screened and further validated based on the ADR-induced mouse model. An integrative approach combining network mapping, molecular docking, and molecular dynamics simulation was performed to identify the representative BACs. Based on an ADR-induced myocardial injury mouse model, HBF significantly ameliorated myocardial injury by improving body weight loss, decreasing mortality, and rescuing severe cardiac fibrosis. A total of 361 ADR-related genes and 42 HBF therapeutic effect-related genes were identified with the thresholds P\u00a0<\u00a00.05 and fold change (FC)\u00a0>\u00a01.2 or\u00a0<\u00a00.833. Transcriptomic profiling-based networks demonstrated that the nuclear factor erythroid 2-related factor 2 (NRF2)-cyclic AMP-dependent transcription factor ATF-3 (ATF3)-sulfiredoxin-1 (SRXN1) axis-mediated ferroptosis was the key target of HBF against myocardial injury. In vivo validation showed that HBF treatment effectively inhibited serum enzymatic biomarkers of general myocardial injury (aspartate aminotransferase, lactate dehydrogenase, and creatine kinase), myofibroblast activity (transforming growth factor beta 1 and \u03b1-smooth muscle actin), inflammatory cytokines (tumor necrosis factor-\u03b1 and interleukin-6), oxidative damage (superoxide dismutase, malondialdehyde, accumulated iron content, and TUNEL-positive cells). Mechanically, HBF may restore the dysregulation of the NRF2-ATF3-SRXN1 signal axis, leading to inhibition of ferroptosis-associated protein expression. Emodin, rhein, and lactiflorin were identified as the underlying representative BACs of HBF against myocardial injury due to the strong binding affinities between candidate BACs and key targets [Kelch-like ECH-associated protein 1 (KEAP1), ATF3, SRXN1, system Xc- (SLC3A2/SLC7A11), glutathione peroxidase 4 (GPX4), ferroportin (FPN), glutathione synthetase (GSS)]. Molecular dynamics simulations further verified these findings, revealing the stable binding among the three components and the key targets. HBF may attenuate ADR-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated ferroptosis, and emodin, rhein, and lactiflorin are potential representative BACs."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS. ClinicalTrials.gov registration: NCT05903690 ."

However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36.

Numerous studies have shown that Huashi Baidu formula (HBF) may exert a satisfactory effect on myocardial function repair. This study aims to reveal the underlying mechanisms and main bioactive compounds (BACs) of HBF against myocardial injury. Firstly, this study established an ADR-induced mouse model to assess the protective effects of HBF against myocardial injury. Subsequently, transcriptomic profiling was conducted to screen the differentially expressed genes among the HBF treatment, ADR-induced model, and normal control groups. Following the construction and analysis of protein-protein interactions, gene set enrichment analysis, and co-expression matrix, the key targets of HBF against myocardial injury were screened and further validated based on the ADR-induced mouse model. An integrative approach combining network mapping, molecular docking, and molecular dynamics simulation was performed to identify the representative BACs. Based on an ADR-induced myocardial injury mouse model, HBF significantly ameliorated myocardial injury by improving body weight loss, decreasing mortality, and rescuing severe cardiac fibrosis. A total of 361 ADR-related genes and 42 HBF therapeutic effect-related genes were identified with the thresholds P\u00a0<\u00a00.05 and fold change (FC)\u00a0>\u00a01.2 or\u00a0<\u00a00.833. Transcriptomic profiling-based networks demonstrated that the nuclear factor erythroid 2-related factor 2 (NRF2)-cyclic AMP-dependent transcription factor ATF-3 (ATF3)-sulfiredoxin-1 (SRXN1) axis-mediated ferroptosis was the key target of HBF against myocardial injury. In vivo validation showed that HBF treatment effectively inhibited serum enzymatic biomarkers of general myocardial injury (aspartate aminotransferase, lactate dehydrogenase, and creatine kinase), myofibroblast activity (transforming growth factor beta 1 and \u03b1-smooth muscle actin), inflammatory cytokines (tumor necrosis factor-\u03b1 and interleukin-6), oxidative damage (superoxide dismutase, malondialdehyde, accumulated iron content, and TUNEL-positive cells). Mechanically, HBF may restore the dysregulation of the NRF2-ATF3-SRXN1 signal axis, leading to inhibition of ferroptosis-associated protein expression. Emodin, rhein, and lactiflorin were identified as the underlying representative BACs of HBF against myocardial injury due to the strong binding affinities between candidate BACs and key targets [Kelch-like ECH-associated protein 1 (KEAP1), ATF3, SRXN1, system Xc- (SLC3A2/SLC7A11), glutathione peroxidase 4 (GPX4), ferroportin (FPN), glutathione synthetase (GSS)]. Molecular dynamics simulations further verified these findings, revealing the stable binding among the three components and the key targets. HBF may attenuate ADR-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated ferroptosis, and emodin, rhein, and lactiflorin are potential representative BACs."

Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement. Reprogramming central-peripheral immune crosstalk with PBM resolves neuroinflammation and restores cognition in AD models-a translatable strategy for combating neurodegeneration."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards."

This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers."

Diagnostic practices have transitioned to universal testing for both familial and sporadic ALS, supported by the approval of gene-targeted therapies. Mechanistically, research has moved beyond simple oxidative stress models, identifying mutant SOD1 as a catalyst for reactive oxygen species generation and exploring the roles of microglial phagocytosis and SOD1-mediated protein misfolding in disease progression.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe landscape of SOD1-linked ALS management has undergone a paradigm shift, characterized by the integration of proactive genetic testing and personalized medicine. Recent clinical data and mechanistic studies confirm that SOD1 mutations drive complex pathogenesis involving neuroinflammation, excitotoxicity, and protein misfolding. \"Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025.\" This reflects the increased availability of targeted treatments such as tofersen, whose clinical distribution has been confirmed in human autopsy tissues. \"For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy.\" Furthermore, research has refined our understanding of motor neuron resilience: \"These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Biomarker Evolution:** Neuromuscular ultrasound now provides non-invasive diagnostic capabilities that match or precede traditional electroneurographic markers in SOD1G93A models.\n*   **Mechanism Redefined:** Mutant SOD1 acts as both a Fenton-like catalyst for hydroxyl radical generation and a hydrogenation catalyst for hydrogen scavenging.\n*   **Genetic Prevalence:** Population-specific data, such as that from Indian cohorts, demonstrate that SOD1 is the predominant cause of familial ALS, even when other repeat expansions (e.g., C9orf72) are present at low frequencies.\n*   **Systemic Involvement:** ALS motor neuron disease is increasingly viewed as a multisystem disorder where innate immune crosstalk, specifically between cGAS-STING and NLRP3 inflammasomes, drives progression.\n*   **Proactive Planning:** Nationwide adoption of genetic testing in Canada was significantly accelerated by proactive planning during the clinical trial phase of gene-targeted therapies.\n*   **Microglial Dynamics:** SGK1 has been identified as a key regulator of microglial phagocytosis; its inhibition attenuates motor deficits, suggesting it as a potential therapeutic target.\n*   **Future Demand:** Projections indicate a significant increase in ALS clinic visits among asymptomatic gene carriers, requiring substantial expansion of clinical infrastructure by 2035.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While ASO-mediated SOD1-lowering therapy remains a primary focus, efficacy is being evaluated through longitudinal multi-analyte profiling, including NfL, GFAP, and UCHL-1. Research is increasingly addressing the biological limitations of SOD1-targeting in non-SOD1 disease, the role of oligogenic susceptibility, and the emergence of \"hydrogen therapy\" and immune-modulatory candidates as adjuncts to standard care.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic landscape for SOD1-ALS is characterized by the validation of gene-targeted platforms and the concurrent recognition of the disease's heterogeneous molecular nature. Recent longitudinal studies emphasize that \"longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.\" The mechanistic underpinnings of motor neuron loss in these models are increasingly attributed to the dual role of mutant SOD1, wherein \"mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species.\" Clinical management is shifting toward early detection via non-invasive modalities, as \"Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests.\" Furthermore, the potential for non-SOD1 pathology requires rigorous biomarker assessment, as evidence indicates that \"the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The application of magnesium-silicide based hydrogen gas release serves as an innovative strategy to intercept the crosstalk between oxidative stress and neuroinflammation.\n*   The use of Platelet Factor 4 (PF4) demonstrates a selective neuroprotective benefit in SOD1-driven ALS, bypassing PINK1-dependent mechanisms to restore proteostasis.\n*   The phenomenon of macrophage inclusions (\"tofersenophages\") in CSF has been identified as a persistent, albeit clinically ambiguous, finding during ASO therapy, which surprisingly correlates with favorable clinical outcomes.\n*   Neuromuscular ultrasound serves as a high-sensitivity, non-invasive biomarker that detects disease pathology at stages prior to electroneurographic abnormalities.\n*   Genetic testing for ALS has achieved near-universal integration in clinical practice by 2025, with sponsored, cost-free testing panels significantly increasing diagnostic yields in sporadic cases.\n*   The identification of the JAK2 gene as a novel genome-wide significant signal in the Indian cohort underscores the importance of population-specific genetic surveying.\n*   The integration of phase-resolved geometric deep learning (SKALE 2.0) now allows for the constraint-aware design of aggregation suppressors that differentiate between nucleation and elongation phases.\n*   The existence of oligogenic models (e.g., ATXN2/NEK1) highlights the complexity of ALS, where pathogenicity may be governed by the synergy of multiple low-penetrance variants rather than monogenic drivers.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The therapeutic focus has moved decisively toward reducing mutant SOD1 protein levels, with intrathecal tofersen emerging as a cornerstone intervention. Clinical data confirm robust target engagement, characterized by significant reductions in cerebrospinal fluid SOD1 protein and plasma neurofilament light chain (NfL) levels. Concurrently, basic research has elucidated the role of copper homeostasis in SOD1 stability, identifying that pathological copper overload can paradoxically suppress SOD1 activity via COMMD1, thereby exacerbating oxidative stress. Moreover, the crosstalk between oxidative stress and neuroinflammation is now viewed as a critical therapeutic target, with hydrogen therapy and immune checkpoint modulation (e.g., LAG-3) showing promise in preclinical models for preserving neuromuscular integrity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Copper Paradox:** High intracellular copper can inhibit SOD1 by disrupting its homodimerization, mediated by COMMD1-dependent mechanisms.\n*   **Catalytic Hydrogen Therapy:** Mutant SOD1 acts as both a Fenton-like agent producing hydroxyl radicals and a catalyst for hydrogen-based free radical scavenging.\n*   **Microglial LAG-3:** This immune checkpoint protein exerts stage-dependent regulation on microglial modules, dissociating inflammatory and phagocytic functions in ALS progression.\n*   **Prion-like Propagation:** Conversion of SOD1 into a misfolded isoform is a targetable biophysical process distinct from aggregation.\n*   **Statin Effects:** While statins can modulate antioxidant genes, they may also inadvertently accelerate prion-like conversion of SOD1 in some experimental contexts.\n*   **Computational Pathology:** Dynamic convolution networks (ODConv) can now distinguish SOD1-associated skeletal muscle pathology from other metabolic disorders using histopathological imagery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This evolution is driven by the regulatory approval and clinical integration of antisense oligonucleotides and siRNA-conjugates. Simultaneously, research has expanded to include systemic factors\u2014such as platelet-derived factors and autophagy-regulating small molecules\u2014and a high-resolution understanding of the \"disease-associated motor neuron\" (DM) state, which provides a conserved molecular roadmap for future therapeutic targeting.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe field of SOD1-ALS has undergone rapid transformation, defined by the clinical maturity of targeted gene-lowering therapies. The integration of such interventions into standard care has necessitated nationwide shifts in genetic testing protocols, as evidenced by the observation that 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Mechanistic studies now link toxic protein aggregation with converging cellular stressors, including mitochondrial failure and oxidative dysregulation. Emerging therapies target these specific pathological vulnerabilities; for instance, hydrogen gas scavenging and autophagic modulation demonstrate efficacy in preclinical SOD1-G93A models. The complexity of these interactions is reinforced by the identification of discrete \"disease-associated motor neuron\" states that precede physical degeneration, providing a temporal window for early therapeutic intervention. Despite these strides, research continues to navigate the clinical challenges posed by phenotypic dissociation and the limitations of targeting single proteins in a multifaceted neurodegenerative cascade.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Pathology-Selective Efficacy:** Therapeutic interventions like PF4 demonstrate robust rescue in SOD1-driven models but remain ineffective in TDP-43 or C9orf72 models.\n*   **Systemic Autophagy:** The discovery of a peripheral platelet-autophagy-neuron axis allows systemic factors to directly influence central proteostatic machinery.\n*   **Temporal Precision:** The identification of \"disease-associated motor neurons\" (DMs) suggests that motor neuron vulnerability is a staged molecular trajectory, not an abrupt event.\n*   **Hydrogen Therapy:** Mutant SOD1 acts as both a catalyst for hydroxyl radical generation and a potential hydrogenation catalyst, allowing for novel hydrogen-based scavenging therapies.\n*   **Diagnostic Evolution:** The shift from familial-only testing to universal screening for sporadic ALS reflects a clinical standard redefined by the availability of disease-modifying therapies.\n*   **Phenotypic Dissociation:** There is growing clinical recognition of biomarker-clinical dissociation, where functional decline may not always mirror molecular marker trends.\n*   **Targeting the Microenvironment:** Modulating the TREM2-mediated inflammatory state of microglia represents a viable pathway for slowing disease progression.\n*   **Compensatory Homeostasis:** SOD1-G93A spinal motoneurons display \"overactive\" homeostatic control, suggesting that dysfunction involves failed feedback regulation rather than simple excitability shifts.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence confirms that while therapeutic SOD1-lowering strategies like tofersen and siRNA-conjugates show promise, outcomes can be heterogenous, and targeting non-SOD1 pathways remains a critical frontier.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis of recent literature indicates that SOD1-targeting therapies have achieved reliable reduction of protein levels in human central nervous system tissues. However, the diagnostic and prognostic landscape is increasingly reliant on multimodal biomarkers, including neurofilament light chain (NfL) and neuromuscular ultrasound, to manage the clinical complexity of SOD1-ALS and potential therapeutic failures in non-SOD1 patient cohorts.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic landscape for SOD1-ALS has undergone rapid evolution, marked by the clinical validation of antisense oligonucleotides (ASOs) and siRNA-based strategies. The distribution of tofersen in human central nervous system tissues has been confirmed, showing that \"In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model.\" While these molecular interventions show efficacy in reducing protein levels\u2014confirmed as \"The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study\"\u2014the clinical response can be paradoxical.

With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide.\nThese findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission.\nClinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025.\nClinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025.\nFor 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy.\nHere, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species.\nThis first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency.\nIn year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers.

microglial phagocytic activity during disease progression in SOD1G93A mice.\nDysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS).\nFCPs upregulated the expression of antioxidant genes sod-1, sod-3, ctl-2, ctl-3 and gst-4.\nreductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite

SOD1, TDP-43, MAPT, and PRNP, SKALE 2.0 recovered a conserved latent transition from nucleation to elongation while resolving distinct mutation-specific phase sensitivities.\nOf the 170 medical records reviewed, 22 patients (12.9%) tested positive for a disease-causing variant in a known autosomal dominant disorder.\nIn 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model.\nThis enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function.\nMechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS.\nThe ability of the assay to identify compounds effective at

cofactors, forms more compact and kinetically distinct oligomers via monomeric, dimeric and trimeric intermediates.\nNo associations were observed for SOD1 (rs36232792) and PER3 (rs57875989) variants.\nIdentification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials.\nZebrafish have been used to successfully model several neurodegenerative diseases, including Alzheimer's disease (via tau phosphorylation and amyloid-beta aggregation), Parkinson's disease (via dopaminergic neuronal loss and alpha-synuclein pathology), Huntington's disease (via polyglutamine-expanded huntingtin), and amyotrophic lateral sclerosis (via mutant SOD1 and TDP- 43 transgenes).\nMechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity.\nPoly (I:C) increased reactive oxygen species (ROS), resulting in a ROS-dependent up-regulation of antioxidants (Catalase, superoxide dismutase (SOD)1 and heme oxygenase (HMOX)1) and Nrf2.\nreductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy.\nThese results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS.\n61% of respondents reported that Health Canada approval of tofersen directly influenced their practice.\nRemarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models.\nHere, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species.\nThis study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs.\nOur findings show a relevant association between hyperphosphatemia and mitochondrial dysfunction, and they support the potential benefit of phosphate reduction as a strategy to prevent or mitigate sarcopenia.\nThe expression levels of CAT, copper (Cu)/zinc (Zn)-superoxide dismutase (Cu/Zn-SOD), heat shock protein 70 (HSP70), heat shock protein 90 (HSP90), and metallothionein (MT2) genes were significantly upregulated.\nAdditionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001).\nreductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having

sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission.\nSystemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation.\nIn tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case.\nNotably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset.\nChanges in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model.\nPeripheral immune cell infiltration and crosstalk with brain-resident cells critically drive Alzheimer's disease (AD)-associated neuroinflammation, highlighting its therapeutic potential.\nIn a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to

disease.\nThese disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies.\nAmong the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity.\nDysbiosis can compromise the integrity of the intestinal barrier, increasing permeability and the translocation of pathogen-associated molecular patterns (PAMPs), such as lipopolysaccharides (LPS), thereby releasing inflammatory cytokines, including IL-6 and TNF-\u03b1.\nNotably, we observed a significant elevation in mannosylation and mono-sialylation of CSF in cases of DEE.\nSystemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects:

years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model.\nThe key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study.\nAlong with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases.\nHBF may attenuate ADR-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated

Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5).

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability."

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

The physicochemical properties of the FCPs were then characterized, and the anti-aging effects of FCPs were evaluated in Caenorhabditis elegans (C. elegans). It was demonstrated that FCPs significantly extended the lifespan of the nematodes, while improving locomotor activity without affecting the body size or reproductive capacity. Meanwhile, FCPs reduced lipofuscin accumulation, decreased intracellular reactive oxygen species (ROS) levels, and increased the survival of C. elegans under oxidative stress. Moreover, FCPs upregulated the expression of antioxidant genes sod-1, sod-3, ctl-2, ctl-3 and gst-4. The expression of skinhead-1 (skn-1), a homologue gene of mammalian nuclear factor erythroid 2-related factor (Nrf) in C. elegans, was also elevated upon FCPs treatment. Knockdown of skn-1 expression by RNA interference abolished the lifespan extension and ROS reduction in FCPs-treated C. elegans, indicating that the SKN-1-mediated signaling was essential for the anti-aging effects of FCPs. Additionally, FCPs caused downregulation of the key components of the insulin/IGF-1 signaling (IIS) pathway, age-1, akt-1, and akt-2.

Diagnostic practices have transitioned to universal testing for both familial and sporadic ALS, supported by the approval of gene-targeted therapies. Mechanistically, research has moved beyond simple oxidative stress models, identifying mutant SOD1 as a catalyst for reactive oxygen species generation and exploring the roles of microglial phagocytosis and SOD1-mediated protein misfolding in disease progression.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe landscape of SOD1-linked ALS management has undergone a paradigm shift, characterized by the integration of proactive genetic testing and personalized medicine. Recent clinical data and mechanistic studies confirm that SOD1 mutations drive complex pathogenesis involving neuroinflammation, excitotoxicity, and protein misfolding. \"Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025.\" This reflects the increased availability of targeted treatments such as tofersen, whose clinical distribution has been confirmed in human autopsy tissues. \"For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy.\" Furthermore, research has refined our understanding of motor neuron resilience: \"These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Biomarker Evolution:** Neuromuscular ultrasound now provides non-invasive diagnostic capabilities that match or precede traditional electroneurographic markers in SOD1G93A models.\n*   **Mechanism Redefined:** Mutant SOD1 acts as both a Fenton-like catalyst for hydroxyl radical generation and a hydrogenation catalyst for hydrogen scavenging.\n*   **Genetic Prevalence:** Population-specific data, such as that from Indian cohorts, demonstrate that SOD1 is the predominant cause of familial ALS, even when other repeat expansions (e.g., C9orf72) are present at low frequencies.\n*   **Systemic Involvement:** ALS motor neuron disease is increasingly viewed as a multisystem disorder where innate immune crosstalk, specifically between cGAS-STING and NLRP3 inflammasomes, drives progression.\n*   **Proactive Planning:** Nationwide adoption of genetic testing in Canada was significantly accelerated by proactive planning during the clinical trial phase of gene-targeted therapies.\n*   **Microglial Dynamics:** SGK1 has been identified as a key regulator of microglial phagocytosis; its inhibition attenuates motor deficits, suggesting it as a potential therapeutic target.\n*   **Future Demand:** Projections indicate a significant increase in ALS clinic visits among asymptomatic gene carriers, requiring substantial expansion of clinical infrastructure by 2035.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Glabridin (Glab), a natural flavonoid derived from licorice, has been shown to mitigate stress-related damage due to its antioxidant properties. This study aims to assess the impact of Glab on OS-induced damage in the bovine immortalized cell line (BIECs-21), validate its effectiveness in vivo, and elucidate the underlying mechanisms. The in vitro OS model of BIECs-21 was established using 400 \u03bcM H2O2. The study evaluated cell viability, lactate dehydrogenase (LDH) activity, oxidative markers, inflammatory responses, and apoptosis in BIECs-21 under various treatment conditions. Additionally, the effects of Glab were investigated in a murine model of experimental colitis induced by dextran sulfate sodium (DSS). Glab improved cell viability, reduced LDH release, and mitigated the adverse effects of H2O2 on total anti-oxidation capacity (T-AOC), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) levels. qRT-PCR analysis revealed that H2O2 exposure resulted in decreased expression of nuclear factor erythroid 2-related factor 2 (Nrf2), superoxide dismutase 1 (SOD1), NADPH quinine oxidoreductase-1 (NQO1), and heme oxygenase-1 (HO-1), while it increased the expression of nuclear factor-kappa B (NF-\u03baB), tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-6 (IL-6), and interleukin-8 (IL-8), ultimately leading to apoptosis in BIECs-21. Notably, Glab supplementation partially reversed these effects. Similar benefits of Glab were observed in a DSS-induced colitis mouse model. Glab reduces OS-induced apoptosis in vitro and in vivo by enhancing antioxidant capacity and reducing inflammation.\n\nID: 42489267\nTitle: A Blood-Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN-Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1.\nAbstract: Peripheral factors that systemically regulate amyotrophic lateral sclerosis (ALS) have remained elusive-until now. Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n\nID: 42484074\nTitle: SOD1-lowering therapy for patients with wildtype SOD1-ALS: a case report.\nAbstract: Background and Objectives: To describe clinical and biomarker experience using an SOD1 antisense oligonucleotide (ASO) in a patient with non-SOD1 amyotrophic lateral sclerosis (ALS). Methods: Case report. Results: In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease. The time from symptom onset to death was 9\u2009months. Discussion: While treatment was initiated relatively late (\u223c7\u2009months) after symptom onset and follow-up duration was short, the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.\n\nID: 42479071\nTitle: Effects of six weeks of hypoxia and hypoxic SIT on oxidative stress and myokine responses in skeletal muscle of high-fat-fed ApoE-/- mice.\nAbstract: Atherosclerosis-induced oxidative stress drives skeletal muscle myopathy in peripheral artery disease, yet the combined effects of hypoxia and hypoxia sprint interval training (SIT) remain unclear. The present study was designed to evaluate how a six-week regimen of hypoxia exposure and SIT influences redox balance and myokine production in the skeletal muscle of high-fat diet (HFD) (21% fat, 1.5% (w/w) cholesterol; 43% (w/w) sucrose-free carbohydrate, 4.554\u00a0kcal/g)-fed atherosclerotic ApoE-/- mice. Forty male ApoE-/- mice fed a HFD were randomly assigned to four groups: Control-Normoxia, Control-Hypoxia, SIT-Normoxia, and SIT-Hypoxia. The hypoxia protocol involved exposures to 11.2% oxygen three times (40\u00a0min each) per week. Key assessment parameters included plasma lipid profiles, skeletal muscle reactive oxygen species (ROS), protein carbonyls, key components of the Nrf2 antioxidant pathway, glutathione metabolism, and myokine-related markers. Compared with the control group, both hypoxia and SIT-Normoxia significantly reduced levels of ROS, protein carbonyls, and Vegfa165 mRNA expression in the skeletal muscle. Hypoxia alone enhanced the levels of GSH-synthesizing enzymes and promoted myokine production. SIT-Normoxia improved plasma lipid profiles, activated the Nrf2 pathway, enhanced the GSH system, and upregulated myokines. SIT under hypoxia further reduced ROS and Vegfa165 while increasing plasma HDL-C and levels of SOD1 protein in the skeletal muscle, but failed to synergistically activate the Nrf2 pathway or enhance GSH production. Paradoxically, both intervention combinations suppressed the mRNA expression of myokine precursor Fndc5, BAIBA-synthesizing enzyme Hadh and Hadha. Overall, six weeks of isolated hypoxia exposure or SIT training independently reduced oxidative stress and promoted beneficial myokine responses in the skeletal muscle of ApoE-/- mice fed a HFD. The wild-type (WT) mice fed a low-fat diet (LFD) was included to validate successful induction of hyperlipidemia, vascular remodeling, and skeletal muscle oxidative stress in ApoE-/- mice after six weeks of HFD feeding.\n\nID: 42469634\nTitle: Secretory leukocyte protease inhibitor (SLPI) attenuates TLR4/NF-\u03baB-mediated neuroinflammation in amyotrophic lateral sclerosis: a candidate molecule associated with neuro-pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons. While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.\n\nID: 42467070\nTitle: Pivotal Factors in Breast Cancer Molecular Subtypes Apoptosis Induction by ELF-EMF; Ki-67, ROS Level, HER-2, and SODs.\nAbstract: Although increasing research has shown that extremely low-frequency electromagnetic fields (ELF-EMFs) specifically trigger PCD through the elevation of ROS levels in cancer cells, there is no adequate evidence to determine the exact mechanisms of this phenomenon. The antioxidant machinery may play a crucial role in this area; however, this has been neglected in previous research. The main aim of this study was to assess the effect of ELF-EMF exposure (5\u2009days, 1\u2009Hz, 100\u2009mT, 2\u2009h/day) on ROS levels, expression levels of antioxidant genes, and apoptosis induction in different breast cancer molecular subtypes with different p53 statuses. DCFH-DA results revealed that the ROS level increased in all three cell lines (SKBR-3, MDA-MB-231, and MCF-7); this increase was much greater in SKBR-3 (up to 5-fold compared to its sham exposure). This result was concurrent with the annexin V/PI results; SKBR-3\u2009cells showed much more apoptosis induction (about 78%), compared with the others (22% or 11% in the other two cells). On the other hand, the mRNA expression level of SOD1 and SOD2 increased significantly in the MDA-MB-231, in addition to these two genes, the expression level of SOD3 and GSR increased in the MCF-7\u2009cells but not in the SKBR-3. Taken together, our results confirmed that ELF-EMF induced ROS-dependent apoptosis, especially in HER-2-enriched breast cancer cells (the SKBR-3), in a p53-independent manner. Other molecular subtypes (MDA-MB-231 as TNBC, or MCF-7 as luminal A) showed resistance against the ROS level increasing and subsequent apoptosis induction by using antioxidant genes, especially SOD1.\n\nID: 42465739\nTitle: Development and efficacy of ex vivo expanded autologous regulatory T cells for the treatment of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited therapeutic options, in which neuroinflammation critically drives disease progression. Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.\n\nID: 42458007\nTitle: Oligonucleotide-siRNA conjugate for SOD1 amyotrophic lateral sclerosis: a phase 1 trial.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease partly caused by gain-of-function mutations in superoxide dismutase 1 (SOD1). Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS.

However, the global transcriptomic landscape underlying stress-induced hepatic injury remains incompletely understood. In this study, we employed a methionine-choline-deficient (MCD) diet-induced murine model to characterize the phenotypic and transcriptomic alterations associated with liver injury. Male C57BL/6J mice were fed either a control or MCD diet, and hepatotoxicity was assessed by survival analysis, body and liver weight measurements, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, histopathological examination, RNA sequencing, quantitative real-time PCR (qRT-PCR), and tumor necrosis factor-alpha (TNF-\u03b1) enzyme-linked immunosorbent assay (ELISA). MCD feeding markedly reduced survival and body weight while inducing hepatomegaly and significant elevations in serum ALT and AST, indicating severe hepatocellular injury. Histopathological analysis demonstrated hepatic steatosis, hepatocellular ballooning, and lobular inflammation without histological evidence of fibrosis. Transcriptomic profiling revealed extensive gene expression remodeling, characterized by activation of inflammatory pathways, enrichment of MAPK-related signaling, dysregulation of lipid metabolism, suppression of antioxidant defense systems, impairment of cytochrome P450-mediated detoxification, and upregulation of apoptosis-associated genes. qRT-PCR further validated the differential expression of representative genes involved in inflammatory signaling (Tlr4, Nfkb1, Nlrp3, and Casp1), MAPK signaling (Fos), xenobiotic metabolism (Cyp4f18), lipid metabolism (Apoa4 and Lpl), extracellular matrix remodeling (Mmp12), and oxidative stress responses (Sod1 and Gstp1). In addition, elevated serum TNF-\u03b1 levels provided protein-level evidence supporting activation of the TLR4/NF-\u03baB/TNF-\u03b1/NLRP3 inflammatory axis. Although fibrosis-associated transcriptional responses were detected, the absence of histological fibrosis suggests transcriptional priming of fibrogenic pathways rather than established fibrogenesis. Collectively, these findings provide a transcriptomic framework linking oxidative stress, impaired detoxification, inflammatory activation, and stress-responsive signaling to MCD-induced hepatic injury. The MCD model provides a valuable experimental platform for characterizing hepatic stress-response transcriptomes and for generating hypotheses that can subsequently be evaluated in environmentally relevant toxicological models. Nevertheless, caution should be exercised when extrapolating these findings to obesity-associated human MASLD, as the MCD model lacks key metabolic features of the human disease, including obesity and insulin resistance. Therefore, the present findings should be interpreted primarily as transcriptomic signatures of stress-induced hepatic injury rather than as a direct representation of the pathophysiological processes underlying human obesity-associated MASLD.\n\nID: 42450273\nTitle: Microvesicle-Derived Redox Signatures as Mediators of Endothelial Dysfunction in Diabetes.\nAbstract: Chronic hyperglycemia and excessive reactive oxygen species (ROS) production are defining features of endothelial dysfunction, a key driver of diabetic vascular complications such as diabetic nephropathy. Microvesicles (MV-enriched fraction), a subtype of extracellular vesicles, and the stress-responsive antioxidant protein Sestrin2 (SESN2) have emerged as important contributors to these processes. This study investigated the role of the MV-enriched fraction in endothelial cell communication under diabetic conditions, with a particular focus on oxidative stress signaling. To model diabetic injury, EA.hy926 endothelial cells were treated with methylglyoxal (MGO), and the resulting MV-enriched fraction was isolated and then applied to two recipient models: na\u00efve endothelial cells and SESN2 knockdown (KD) cells. Protein expression of key antioxidant markers, including endothelial nitric oxide synthase (eNOS), was assessed by Western blot. Nitric oxide (NO) bioavailability was quantified via nitrite measurement using 2,3-diaminonaphthalene (DAN), while mitochondrial and cytosolic ROS levels were evaluated using MitoSOX and dihydroethidium (DHE), respectively. Results demonstrated that the MV-enriched fraction derived from diabetic conditions triggers a complex antioxidant response in healthy endothelial cells, characterized by upregulation of SESN2, superoxide dismutase 1 (SOD1), and heme oxygenase-1 (HO-1). This suggests a compensatory mechanism that mitigates oxidative stress. Notably, SESN2 KD cells exhibited increased ROS production and reduced NO levels upon MV treatment, underscoring the essential role of SESN2 in maintaining redox homeostasis. Overall, this study highlights the dual role of the MV-enriched fraction as a mediator of both protective and detrimental redox signaling in diabetic endothelial dysfunction and suggests potential therapeutic targets for managing diabetic vascular complications.\n\nID: 42450113\nTitle: Serum Copper-to-Zinc Ratio and Oxidative Stress Are Associated with Anemia in Older Adults with Cardiovascular-Kidney-Metabolic Syndrome.\nAbstract: Chronic oxidative stress is a molecular hallmark of cardiovascular-kidney-metabolic (CKM) syndrome, yet its contribution to CKM-associated anemia beyond erythropoietin deficiency and iron restriction is poorly characterized. The serum copper-to-zinc (Cu/Zn) ratio reflects impaired Cu/Zn-SOD1 antioxidant capacity and inflammatory trace-element imbalance, but its relationships with circulating redox biomarkers and its hematological relevance in CKM syndrome has never been explored in a community-dwelling cohort of older adults. We analyzed 2391 NHANES 2011-2016 participants \u2265 50 years of age with CKM stage I-IV. To explore whether the serum Cu/Zn ratio was associated with oxidative stress and immunomodulatory biomarkers as well as with the odds of anemia, we used survey-weighted Spearman correlations, linear regression (outcome: hemoglobin), and logistic regression (outcome: anemia); multivariate models were adjusted for a panel of antioxidant or immunomodulatory biomarkers (selenium, vitamin D), pro-oxidant biomarkers (lead, cadmium, cotinine, uric acid), red cell distribution width (RDW) as a composite biomarker of erythrocyte stress, neutrophil-to-lymphocyte ratio (NLR), CKM stage, and comorbidities. The molecular targets of the nine biomarkers were mapped onto a protein-protein interaction network using the STRING database v12.0 to contextualize regression findings within a systems biology framework. Anemia was present in 205 participants (8.6%). The Cu/Zn ratio was inversely correlated with the antioxidant marker selenium (r = -0.19; p < 0.001) and positively correlated with the pro-oxidant markers RDW (r = +0.21; p < 0.001) and cadmium (r = +0.10; p < 0.001), consistent with its role as a hub within the CKM redox network. In fully adjusted models, a higher Cu/Zn ratio was independently associated with prevalent anemia (OR = 2.94; 95% CI: 1.61-5.37) and lower hemoglobin (\u03b2 = -0.55 g/dL); among included biomarkers, selenium and cadmium were independently protective (OR = 0.76 per 10 \u00b5g/L and 0.23 per \u00b5g/dL, respectively), and RDW and uric acid were independently harmful (OR = 2.20 per 1% and 1.33 per mg/dL, respectively). The Cu/Zn ratio correlated with both antioxidant depletion and pro-oxidant accumulation in CKM syndrome and was independently associated with anemia within this oxidative network. Together with selenium, cadmium, RDW, and uric acid, it defines an oxidative stress-driven hematological pathway that may contribute to the development and progression of anemia in patients with CKM syndrome.\n\nID: 42447970\nTitle: Human umbilical cord-derived mesenchymal stem cells ameliorate muscle dysfunction and metabolic dysregulation in the CuZnSOD null mouse model of sarcopenia.\nAbstract: Age-related sarcopenia is a progressive skeletal muscle disorder driven by oxidative stress and metabolic dysregulation. Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.\n\nID: 42447123\nTitle: Neuromuscular ultrasound as a biomarker in the SOD1 mouse model of amyotrophic lateral sclerosis.\nAbstract: A progression marker that indicates early disease-related changes and treatment responses in the to date incurable neurodegenerative disease amyotrophic lateral sclerosis (ALS) is highly desirable. Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.\n\nID: 42442802\nTitle: The Role of Genetic Alterations in the Emergence of Alzheimer's Disease in Down Syndrome: A Review.\nAbstract: Down syndrome (DS), the most common chromosomal disorder, is associated with an accelerated aging process, increasing the risk of early-onset Alzheimer's disease. This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers.\n\nID: 42442304\nTitle: Amelioration of obesity-induced testicular dysfunction and structural damage by ganoderma lucidum polysaccharides and triterpenoids in rats: Correlation with Nrf2-mediated antioxidant response.\nAbstract: Obesity is a global health crisis and a critical risk factor for male infertility, impairing testicular structure and function through hormonal imbalance and oxidative stress. Current therapeutic strategies are often unsatisfactory due to limited efficacy or adverse effects. This study investigated the protective effects and potential molecular mechanisms of Ganoderma lucidum (GL) polysaccharides and triterpenoids against testicular injury in high-fat diet-induced obese male rats. After 12-week GL intervention, reproductive function in obese male rats showed improvement: GL increased litter size, improved sperm motility, reduced sperm DNA fragmentation, and restored serum testosterone, inhibin B, and leptin levels. It also alleviated testicular histopathological damage, downregulated PPT1, and maintained vimentin expression. Notably, GL facilitated delayed fertility recovery and showed a trend toward improved cumulative reproductive success, although fixed-time pregnancy rates were not significantly changed. Mechanistically, GL is associated with enhanced Nrf2 pathway activity, increased SOD1, HO-1, NQO1, and GPX4 levels, and decreased MDA and ROS accumulation, thereby attenuating oxidative stress. It preserved mitochondrial integrity, suppressed germ cell apoptosis (downregulating Bax and caspase-3, upregulating Bcl-2), and promoted cell proliferation. These findings indicate that GL polysaccharides and triterpenoids effectively ameliorate obesity-induced testicular dysfunction, and these beneficial effects are associated with Nrf2-mediated antioxidant responses, mitochondrial homeostasis, apoptosis regulation, and hormonal balance. GL may serve as a promising candidate for obesity-related male infertility.\n\nID: 42437952\nTitle: NOP56 is essential for mammalian generation and maintenance of multiple central nervous systems, associated with SCA36 pathology.\nAbstract: NOP56, a core nucleolar component involved in small nucleolar ribonucleoprotein assembly, has been genetically implicated in spinocerebellar ataxia type 36. However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097.\n\nID: 42432986\nTitle: Mitoquinone Prevents Cardiac Dysfunction by Normalizing Mitochondrial ROS and Calcium Handling in Acute Myocardial Infarction.\nAbstract: Acute myocardial infarction (MI) is the leading cause of heart failure (HF). However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI. Male Wistar rats were divided into four experimental groups: Sham, Infarct, Sham+MitoQ, and Infarct+MitoQ. MitoQ was administered orally (8\u2009mg/kg/dia) for 7\u2009days. Hemodynamic parameters, infarct area, papillary muscle contractility, cardiomyocyte mechanics, Ca2+ transients, and total and mitochondrial superoxide (DHE and MitoSOX) were assessed. After 7\u2009days of MI, rats exhibited impaired contractility, altered inotropic response to extracellular Ca2+, cardiomyocyte hypertrophy, and increased total and ROSm. MitoQ prevented body weight loss and significantly improved hemodynamic parameters compared to the Infarct group. In papillary muscles, MitoQ restored basal isometric force and the inotropic response to extracellular Ca2+. In cardiomyocytes, it attenuated hypertrophy, preserved shortening, and reduced ([Ca2+]i) transient amplitude. MitoQ significantly decreased total and mitochondrial O2\u2022- production. It selectively reduced NOX1 expression under simulated conditions but did not significantly affect NOX2, SOD1, or catalase expression in the context of MI. MitoQ prevented contractile dysfunction, suggesting that mitochondrial oxidative stress plays a decisive role in myocardial dysfunction during the acute phase of MI. Targeting antioxidant therapy to the mitochondria represents a promising strategy for preventing post-infarction heart failure and opens new perspectives for the development of more effective interventions in the treatment of cardiovascular diseases.\n\nID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the \u03b11 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.\n\nID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.\n\nID: 42425334\nTitle: Comparative screening of Amur tiger cytokines identifies IL-15 as a cytoprotective candidate against feline panleukopenia virus infection.\nAbstract: Comparative studies of species-derived cytokines remain limited in endangered carnivores. We cloned six immune-related cytokines from Amur tigers (Panthera tigris altaica), with sequence analysis revealing >90% identity across Felidae. Among all tested cytokines, IL-15 demonstrated superior and sustained lymphocyte-stimulatory activity at 200\u202fng/mL. To investigate antiviral potential, F81\u202fcells were pretreated with IL-15 and challenged with feline panleukopenia virus (FPV). Mechanistic studies revealed that IL-15 attenuated virus-induced apoptosis by modulating key regulatory proteins: downregulating pro-apoptotic factors (Bax, Caspase3/9, p53, Cytc) while upregulating anti-apoptotic Bcl-2. Additionally, IL-15 preserved mitochondrial integrity by maintaining membrane potential, enhancing fusion proteins (MFN1/MFN2), and suppressing fission protein Drp1. IL-15 also strengthened cellular antioxidant defenses through increased SOD1/SOD2 expression, significantly reducing reactive oxygen species (ROS) accumulation. These protective effects persisted for 48\u202fh post-infection, demonstrating sustained cytoprotective effects. These findings reveal species-specific IL-15-mediated antiviral mechanisms within the Felidae family and provide comparative insights into how immune defenses are optimized in species with constrained evolutionary history, with implications for understanding carnivore immune evolution and conservation medicine.\n\nID: 42419058\nTitle: Redox Imbalance and Impaired Protein Clearance Drive Chronic Liver Injury in Biliary Atresia.\nAbstract: Excessive or uncontrolled generation of reactive oxygen species (ROS) is closely associated with the development of liver diseases. However, direct evidence linking oxidative stress to impaired hepatic function in human biliary atresia (BA) remains limited. To address this, we performed bulk RNA sequencing to investigate (1) alterations in hepatic oxidative stress and antioxidant defense mechanisms and (2) transcriptomic changes associated with impaired hepatic function in BA. Total RNA was extracted from liver samples of patients with BA and non-BA cholestasis. Bulk RNA sequencing and transcriptomic analyses were performed, focusing on redox-related pathways and genes linked to hepatic function. Dual oxidases 1 and 2 were significantly upregulated in BA. In contrast, key ROS-metabolizing enzymes such as catalase, glutathione synthetase, and superoxide dismutase 1 and 2 were downregulated, indicating redox imbalance in BA livers. Excessive ROS can lead to the denaturation of cellular proteins and damage to organelles, which are normally degraded via autophagy and proteasomes. However, both autophagy and proteasome functions were impaired in BA, contributing to sustained inflammation and further ROS production. Transcriptomic analyses also revealed repression of core liver transcription and splicing factors, indicating injury-associated alterations in hepatic transcription programs. BA is characterized by a redox imbalance and dysfunctional protein clearance, forming a vicious cycle of ROS accumulation and inflammation. These changes likely contribute to liver fibrosis and the progressive loss of hepatic function in BA.\n\nID: 42410741\nTitle: In Vitro Skin-Protective Effects of Sumyong Nature, a Kimchi- and Soybean-Derived Fusion-Fermented Microbial Supernatant, in Human Keratinocytes: Involvement of MAPK-Related Signaling.\nAbstract: Sumyong Nature (SN) is a kimchi- and soybean-derived fusion-fermented microbial supernatant prepared from Lactobacillus acidophilus, Saccharomyces cerevisiae, Weissella cibaria, and Bifidobacterium longum. This study examined the in vitro effects of SN on UVB-induced damage and skin-related cellular responses in human keratinocytes. Cell viability assays, gene expression analysis, luciferase reporter assays, immunoblotting, scratch wound-healing assays, and LC-Q-TOF-MS analysis were conducted. SN showed no significant cytotoxicity in HaCaT or HEK293T cells at concentrations up to 75 \u03bcg/mL. In UVB-irradiated HaCaT cells, SN improved cell viability, suppressed MMP-1 expression, increased HAS-1 expression, and modulated UVB-responsive stress-related markers, including SOD-1, Nrf2, and HO-1. SN also promoted wound closure in keratinocytes and was associated with changes in NF-\u03baB-, AP-1-, CREB-, and MAPK-related signaling responses under the tested conditions. LC-Q-TOF-MS analysis tentatively identified several candidate constituents, including pectolinarin and aloeresin-related compounds. Collectively, these findings suggest that SN exerts multiple beneficial in vitro effects in keratinocyte-based assays, warranting further mechanistic investigation and validation in advanced experimental models.\n\nID: 42410102\nTitle: A changed landscape: five-year retrospective on the paradigm shift in genetic testing practices for ALS in Canada.\nAbstract: Offering genetic testing is increasingly recommended for all individuals with amyotrophic lateral sclerosis (ALS), particularly following the development of gene-targeted therapies, such as tofersen for SOD1-ALS. Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards.\n\nID: 42406382\nTitle: Antisense Oligonucleotide Tofersen Distribution in the Central Nervous System of SOD1-ALS Autopsy Tissue Donors.\nAbstract: Tofersen is a disease-modifying antisense oligonucleotide therapeutic for people living with SOD1-amyotrophic lateral sclerosis (SOD1-ALS). Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues.\n\nID: 42402967\nTitle: Hypoxia-preconditioned dental pulp stem cells alleviate acetaminophen-induced liver failure via promoting MYC-HIF1A/HIF-1\u03b1-BNIP3-mediated mitophagy.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is a prevalent clinical liver condition caused mostly by oxidative stress and mitochondrial damage. Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot.\n\nID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n\nID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n\nID: 42397005\nTitle: Covalent Modulation of Protein Misfolding and Aggregation Processes in the Context of Neurodegenerative Diseases.\nAbstract: Misfolded protein aggregates represent major histopathological hallmarks of neurodegenerative diseases, differing in the structural components and brain regions affected. Furthermore, the formed assemblies act as key players in developing and fostering neurotoxic processes, with distinct mechanisms depending on the stage of the amyloid cascade. Particularly, the oligomer intermediates are now considered as the main drivers of neurotoxicity, thus requiring an early antiaggregant therapeutic intervention to achieve a significant neuroprotective efficacy. Among different strategies, direct interaction at early stages preventing aggregation is quite intricate due to the considered undruggability of misfolded monomers. In this context, a covalent approach targeting specific functional nucleophilic residues within disordered proteins can offer an intriguing opportunity to overcome these weaknesses. Therefore, in this review, we outline covalent modulators of misfolding and aggregation processes reported to date, referring to the major misfolded proteins in the neurodegenerative context (i.e., \u03b2-amyloid, tau, \u03b1-synuclein, and superoxide dismutase 1) to highlight their potential both as valuable pharmacological tools or therapeutic perspectives.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42390843\nTitle: Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis.\nAbstract: Superoxide dismutase 1 (SOD1), a copper-dependent antioxidant, is essential for redox homeostasis, and its decline drives renal senescence and fibrosis. However, the mechanisms linking profibrotic signaling to SOD1 inhibition remain unclear. Here, we identified a pathological copper-COMMD1-SOD1 axis in which intracellular copper overload paradoxically suppressed SOD1 activity. In kidney tissues from chronic kidney disease (CKD) patients and complementary in vivo and in vitro fibrotic models, we consistently observed a reduction in SOD1 activity accompanied by elevated intracellular copper levels.\u00a0Lowering intracellular copper levels restored SOD1 activity, suppressed reactive oxygen species (ROS) accumulation, and alleviated cell senescence and fibrosis. Mechanistically, pathological copper overload impaired SOD1 homodimerization, the essential final step in its activation. We identified copper metabolism MURR1 domain containing 1 (COMMD1) as a key copper-sensitive mediator of this process. Copper overload acted upstream, simultaneously upregulating COMMD1 expression and enhancing its binding affinity to SOD1. This enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function. Collectively, these findings redefined the regulatory role of copper in SOD1 activity and uncovered a previously unrecognized mechanism by which pathological copper overload paradoxically suppressed SOD1 activity via COMMD1-dependent disruption of SOD1 homodimerization, providing new insight into the pathophysiology of copper dyshomeostasis-associated diseases.\n\nID: 42387584\nTitle: SGK1-mediated deficits in microglial phagocytosis drive pathological progression in amyotrophic lateral sclerosis.\nAbstract: Alterations in microglial function and transcriptomic profiles are major pathological hallmarks of amyotrophic lateral sclerosis (ALS). However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.\n\nID: 42385849\nTitle: Quercetin and carvacrol act synergistically to inhibit Candida albicans biofilms in vitro via membrane disruption and oxidative stress.\nAbstract: Candida albicans biofilms are a major cause of device-associated infections and treatment failure due to high antifungal tolerance. Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200\u202f\u03bcg/mL (carvacrol) and 240\u202f\u03bcg/mL (quercetin) to 17\u202f\u03bcg/mL and 10.9\u202f\u03bcg/mL, respectively (FICI\u202f=\u202f0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by \u223c64.4% (vs. \u223c56.5% for carvacrol and \u223c51.5% for quercetin alone) and inducing apoptosis-like cell death with robust metacaspase activation supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established.\n\nID: 42385392\nTitle: Biological responses of human astrocytes (SVGp12) and glioblastoma (A172) cells to dendronized \u03b2-cyclodextrin molecular containers: Morphological and molecular insights.\nAbstract: The search for molecular containers that enhance the bioavailability of active substances has opened the development of functionalized \u03b2CD-based molecular containers. In this study, the effects of \u03b2CD-modified with dimethylolpropionic acid (Bis-MPA) dendrons (\u03b2CD-m2G and \u03b2CD-m3G) were evaluated in SVGp12 (non-tumor astrocytes) and A172 (glioblastoma) cells. The dendronized systems exhibited low cytotoxicity (>75% viability) even at high concentrations (90\u00a0\u03bcM, p\u00a0<\u00a00.05). Morphological analyses revealed lipid inclusion bodies (LIBs), suggesting that after intracellular uptake, the dendronized containers promote their formation. \u03b2CD-m3G occupies 12% of the cell volume in SVGp12 and 17% in A172 (p\u00a0<\u00a00.05). Ultrastructural evaluation showed increased smooth endoplasmic reticulum (SER), a finding consistent with enhanced lipid metabolism. Importantly, cell differentiation and endoplasmic reticulum stress, evaluated by the expression of Aquaporin-4 and calnexin, were not impaired (p\u00a0>\u00a00.05). A twofold increase in mGlu-5 expression (p\u00a0<\u00a00.001) was observed in both cell lines due primarily to the \u03b2CD-m3G container. Because neither container induces oxidative stress in the SVGp12 cell line, cell proliferation increases from 41% to 48% (p\u00a0<\u00a00.001) due to \u03b2CD-m2G and \u03b2CD-m3G, respectively. These cells also increased Caspase9 expression (p\u00a0<\u00a00.001), suggesting control of proliferation. However, \u03b2CD increased NRF2 expression by 4.3-fold (p\u00a0<\u00a00.0001) and the expression of SOD1, HMOX1, and PRDX1. \u03b2CD increases 1.8-fold-ROS in A172 cells (p\u00a0<\u00a00.001) versus control. 3.5-fold expression of NRF2 was observed in the presence of NAC (p\u00a0<\u00a00.001). These suggest that only \u03b2CD increases NRF2 and ROS as an adaptive response of A172 cells. The incorporation of amphiphilic dendritic groups enables efficient cellular uptake of \u03b2CD-dendronized containers.\n\nID: 42384233\nTitle: Genome-wide spectrum of coding DNA variations in Indian patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited therapies, emphasizing the need for deeper understanding of disease pathogenesis. While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.\n\nID: 42383461\nTitle: Acute Exposure to Environmentally Relevant Concentrations of Ciprofloxacin and Levonadifloxacin Alters Behavior, Organ Health, and Stress Response in Adult Zebrafish.\nAbstract: Antibiotic pollution in aquatic systems is an emerging global concern, but the sublethal effects of acute exposure on aquatic vertebrates are poorly understood. This study examined the acute toxicity by exposing adult zebrafish to three concentrations (1, 5, and 10\u2009mg/L) of ciprofloxacin (CIP) and levonadifloxacin (LND) for 96\u2009h. Behavioral, histological, biochemical, and transcriptional changes were assessed. In the novel tank-dive test, both antibiotics induced concentration- and time-dependent anxiogenic behaviors, such as reduced exploration, decreased total distance traveled, and less time in the upper zone. Histopathological analysis showed progressive tissue damage beginning in the gill epithelium and spreading to the intestine and muscle. Overall, lesion severity increased with higher concentrations and was consistently higher in CIP-exposed fish. Antioxidant enzyme activity exhibited significant changes in superoxide dismutase, catalase, and glutathione peroxidase 1. Early increase in enzyme levels at 48\u2009h coincided with reduced transcription of sod1, cat1, and gpx1a. At 96\u2009h, transcription levels increased while protein levels remained stable. Pathway analysis grouped these genes within interconnected oxidative stress networks rather than cell death pathways. Overall, the results indicate that exposure to both fluoroquinolones for 96\u2009h causes a staged oxidative stress response, along with behavioral disruptions and tissue damage. CIP caused stronger immediate biological effects than LND at the same concentrations, although both antibiotics disturbed organismal homeostasis at sublethal levels. These findings highlight the ecological importance of short-term antibiotic contamination and demonstrate the value of multiple endpoints for detecting early toxic effects in aquatic organisms.\n\nID: 42381517\nTitle: Proteomic Profiling of Cryopreservation-Induced Alterations in Rhesus Macaque Sperm.\nAbstract: Sperm cryopreservation is a fundamental technique in assisted reproductive technologies. While human sperm freezing is clinically routine, preserving nonhuman primate sperm remains challenging due to species-specific characteristics and low post-thaw viability. This study aims to investigate the proteomic changes in rhesus macaque sperm before and after cryopreservation, focusing on identifying the molecular mechanisms behind cryoinjury. Semen was collected from six sexually mature male rhesus macaques (6-10 years) using rectal electroejaculation. Motility parameters were quantified pre- and postcryopreservation using computer-assisted semen analysis (CASA) with vapor-phase liquid nitrogen protocols. Data-independent acquisition (DIA) quantitative proteomics, combined with LC-MS/MS, was used to profile global protein expression changes. Differential protein analysis was performed using multibioinformatics tools for functional annotation and network modeling. Papanicolaou and acridine orange (AO) staining were used to assess sperm morphology and DNA integrity, while reactive oxygen species (ROS) assay and immunofluorescence were employed to validate the proteomic analysis results. We identified 512 differentially expressed proteins (32 upregulated, 480 downregulated), which are predominantly enriched in pathways related to metabolic reprogramming, oxidative stress response, and protein homeostasis. Immunofluorescence staining further confirmed markedly reduced levels of SOD1, PGK2, PKC\u2011alpha, and phospho\u2011tyrosine in sperm after freeze-thaw cycling. These molecular hubs are associated with sperm motility and functional stability and may be essential for regulating energy metabolism, oxidative balance, and proteotoxicity during cryopreservation-induced stress in rhesus macaque sperm. Cryopreservation induces profound proteomic remodeling in rhesus macaque sperm, mitochondrial electron transport, and metabolic homeostasis. Our findings reveal conserved and species-specific cryoinjury mechanisms, offering molecular targets for optimizing cryopreservation protocols in nonhuman primates to advance reproductive conservation strategies.\n\nID: 42480869\nTitle: Macrophage responses to and elevated antibody levels against Chlorovirus ATCV-1 in ALS patients.\nAbstract: Acanthocystis turfacea chlorella virus 1 (ATCV-1) is a giant virus that is part of the human oral microvirome. Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease.\n\nID: 42375957\nTitle: Application of nano-selenium as a dietary supplement and its effects on antioxidant status and gene expression related to oxidative stress in broiler chickens.\nAbstract: Antioxidants are important factors in reducing stress in poultry birds. Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers.\n\nID: 42375949\nTitle: Reactive oxygen species and intrinsic apoptotic markers in thyroid dysfunction: Insights from experimental animal models.\nAbstract: Thyroid disorders are associated with elevated reactive oxygen species (ROS) levels that trigger apoptosis. Nevertheless, the precise connection between ROS levels and apoptotic markers in thyroid dysfunction remains unclear. To explore the relationship between ROS levels and intrinsic apoptotic (IA) markers in thyroid homogenates derived from hypothyroidism and hyperthyroidism mouse models. Eighteen male Wistar rats, each weighing 240 \u00b1 10 g, were allocated to three groups of six rats. Hypothyroidism and hyperthyroidism were induced over 8 weeks using 0.05% Propylthiouracil (PTU) and 0.0012% Levothyroxine (L-Thy), respectively. T3, T4, and thyroid-stimulating hormone levels were measured, and thyroid size and body weights were recorded. The levels of ROS markers [MDA, glutathione (GSH), SOD-1, CAT, and GPX) and IA markers (Bax, Bcl-2, and caspase-3) were assessed in tissue homogenates. A gradual weight loss was observed in the hyperthyroidism group compared with the control group. The hypothyroid model showed elevated MDA levels and cleaved caspase-3, as well as a higher Bax/Bcl-2 ratio, whereas GSH, SOD-1, CAT, GPX, and Bcl-2 levels were lower than those in the control group (p < 0.05). In contrast, no changes were observed in the hyperthyroid models. Thyroid hormone levels are inversely correlated with ROS and positively correlated with antioxidant levels. Hypothyroidism models exhibited increased oxidative stress and pro-apoptotic markers, suggesting the initiation of apoptosis and cellular damage. Conversely, the hyperthyroid models showed no such changes.\n\nID: 42375264\nTitle: Proteomic profile of seminal plasma in tropical Saanen bucks under heat stress using 1D-SDS PAGE.\nAbstract: Tropical heat and humidity induce oxidative and thermal stress that threaten male fertility. However, the seminal plasma mechanisms that sustain sperm function under these conditions in goats remain poorly understood. This study aimed to evaluate semen quality and characterize the seminal-plasma proteome of Saanen bucks raised under Indonesia's tropical conditions to identify molecular adaptations associated with fertility resilience. Three healthy bucks (five ejaculates each) were examined using computer-assisted sperm analysis (CASA) for sperm motility, viability, abnormality, membrane and acrosome integrity, and kinematics. Seminal-plasma proteins were separated by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and annotated through Gene Ontology enrichment. While most semen traits and kinematics were comparable among bucks, abnormality and acrosome integrity differed significantly (p < 0.05). A conserved extracellular, vesicle-associated proteome was identified-including BSP1, BSP3, BSP5, ANXA5, ALB, HSPA1A, HSP90AA1, CLU, GPX5, and SOD1-with minor inter-individual variation in LTF, FN1, SPP1, and A2M. Enrichment (FDR < 0.05) highlighted the extracellular region, vesicle, and cytokine-regulatory pathways. This study provides the first proteomic evidence of seminal plasma adaptation to THS in Saanen bucks, revealing a stable core of chaperone, antioxidant, and membrane-coating proteins that safeguard sperm function. These findings establish a novel proteomic basis for heat-resilient fertility and support the development of protein-based sire selection and reproductive management tools in tropical dairy-goat systems.\n\nID: 42375253\nTitle: Chlorella vulgaris improves fertility in malnourished male rats by regulating the oxidative state, spermatogenesis, and inflammatory cytokines.\nAbstract: Malnutrition is one of the predisposing factors of disturbance in some physiological functions, including reproductive health. Currently, many people and animals are globally facing micronutrient deficiency, especially in lands with poor soils in organic matter and nutrients. Egyptian soil and, consequently, crops were found to be deficient in micronutrients to varying degrees. This study aimed to investigate the potential fertility-enhancing effects of the microalgae Chlorella vulgaris (CV) on male rats fed a salt-deficient diet. Forty-five adult rats (15 rats each) were divided into three groups (G1, G2, and G3). G1 received a normal balanced diet, G2 received a salt-deprived diet (SD), and G3 was supplemented with SD plus Chlorella 1% of the diet (SD + CV). After eight successive weeks of treatment, the animals were fasted overnight, anesthetized, and sacrificed. The collected plasma was analyzed for organ function-related constituents, oxidative biomarkers, and testosterone levels. Epididymal sperms were also examined. Samples of testis were analyzed for quantitative gene expression of GPX4, SOD1, and SPATA6 genes. Additionally, histopathological examination was performed for testis, liver, and kidney samples. The results obtained from the current study revealed that the plasma of the SD group had higher levels of oxidative biomarkers and inflammatory cytokines, elevated urea, creatinine, and uric acid levels, and liver enzymes, and lower testosterone levels than the normal control group. In addition, lower sperm motility and higher abnormality and downregulation of SPATA6 genes and degenerative changes were found in the testes, liver, and kidneys. The administration of (SD + CV) restored these alterations. CV could be used as a supplement to compensate for nutrient or salt deficiency and correct the resultant disorders, especially reproductive affections, in males.\n\nID: 42371060\nTitle: Mechanism-centered target discovery across glomerulonephritis phenotypes: an integrative multi-omics study.\nAbstract: Glomerulonephritis (GN) comprises a heterogeneous group of immune-mediated kidney disorders with substantial biological and clinical diversity. Current treatment still relies largely on broad immunosuppression, underscoring the need for mechanism-informed target discovery across GN phenotypes. We performed a program-guided integrative multi-omics study by combining cis-expression quantitative trait loci and cis-protein quantitative trait loci with GN genome-wide association datasets from UK Biobank, the GWAS Catalog, and FinnGen. Candidate genes were organized into four predefined mechanistic programs: cytokine/TNF signaling, cell-cycle/senescence-repair balance, complement/innate immune activation, and regulated cell-death/redox stress. Six GN-related outcomes were analyzed. Bayesian colocalization, cross-dataset meta-analysis, mouse knockout annotation, drug-repurposing assessment, network pharmacology, and rule-based evidence scoring were used to refine target prioritization. Integrative screening identified 42 transcriptomic and 12 proteomic putative targets, with the strongest enrichment in non-proliferative glomerulonephritis and primary membranoproliferative glomerulonephritis. Bayesian colocalization supported PPP2R1B in non-proliferative glomerulonephritis, SOD1 in IgA nephropathy, and CDK4 in primary membranoproliferative glomerulonephritis. Among 42 transcriptomic gene-outcome pairs taken forward, 11 were supported by cross-dataset meta-analysis. Proteomic meta-analysis supported several cross-dataset signals, including protective associations of ANXA5, GSR, and TNFRSF1B with glomerulonephritis. Across outcomes, complement/innate immunity and cytokine/TNF signaling formed the dominant shared backbone. After separating MHC-region signals for cautious interpretation, 31 non-MHC targets were retained for primary prioritization, with PPP2R1B, CDK4, and SOD1 comprising the top tier. This mechanism-centered integrative multi-omics study delineates shared and phenotype-enriched biological programs across the GN spectrum and identifies a prioritized set of candidate targets for future validation and therapeutic development.\n\nID: 42367369\nTitle: Preparing Amyotrophic Lateral Sclerosis Clinics to Provide Longitudinal Care for Individuals Carrying ALS Risk Variants.\nAbstract: Emerging genetic therapies and the expansion of genetic testing are identifying individuals carrying amyotrophic lateral sclerosis (ALS) risk variants who would benefit from surveillance and early intervention. Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care.\n\nID: 42364425\nTitle: Effects of SGLT2 inhibitor dapagliflozin on the heart of rats with long-standing Type 1 diabetes mellitus: Protein profile.\nAbstract: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have beneficial outcomes on the renal and cardiovascular system in diabetes mellitus (DM) patients. As most clinical trials were performed in Type 2 DM, the effects of SGLT2 inhibition in Type 1 DM are not completely clarified. To evaluate the effects of long-standing SGLT2 inhibitor dapagliflozin on the protein profile in rats with a Type 1 DM model. Male Wistar rats were divided into Control (C), DM, and DM treated with dapagliflozin (DM+DAPA) for 30 weeks. DM was induced by a single injection of streptozotocin (40\u202fmg/kg); dapagliflozin was added to chow (5\u202fmg/kg/day). Label-free mass spectrometry was used to assess left ventricular proteome. The bioinformatic tools used were STRING, Cytoscape, Cluster Marker, and ClueGO. ANOVA and Tukey or Kruskal-Wallis and Dunn. Dapagliflozin attenuated body weight loss (C 574\u202f\u00b1\u202f43; DM 339\u202f\u00b1\u202f31*; DM+DAPA 413\u202f\u00b1\u202f30*# g; p\u202f<\u202f0.05 * vs C; # vs DM) and reduced glycemia [C 108 (101-111); DM 554 (529-562)*; DM\u202f+\u202fDAPA 343 (237-416)*# mg/dL; p\u202f<\u202f0.05 * vs C; # vs DM]. Most proteins identified in the networks downregulated in DM vs C were upregulated in DM\u202f+\u202fDAPA vs DM. Proteins related to energy metabolism (CKm, Ak1, Atp5pf, Mdh1, Idh2), excitation-contraction coupling (Actc1, Casq2, Serca1, Serca2a), and oxidative stress (Sod1, Sod2) were upregulated in DM\u202f+\u202fDAPA. KEGG pathways enriched in DM vs Control included gap junction, necroptosis, and fatty acid degradation (upregulated), and Alzheimer's disease, cardiac contraction, and glycolysis/gluconeogenesis (downregulated). In DM\u202f+\u202fDAPA vs DM, upregulated pathways included Parkinson's disease, cardiac contraction, citrate cycle, necroptosis, and cyclic guanosine monophosphate-dependent protein kinase (PKG) signaling pathway; downregulated proteins were linked to ketone body metabolism. Dapagliflozin modulates cardiac protein abundance by attenuating DM-induced changes in Type 1 DM rats.\n\nID: 42362003\nTitle: Astragalus polysaccharides alleviate oxidative damage by activating the Keap1-Nrf2 antioxidant pathway through miR-183-5p in a fish cell model.\nAbstract: Astragalus polysaccharides (APS), one of the star antioxidants among traditional Chinese medicine, have widespread applications in healthcare, veterinary, and fishery fields. However, the mechanisms underlying their antioxidative action remain largely unknown. In this study, the protective role of APS in H2O2-induced oxidative damage and associated mechanism were investigated in large yellow croaker head kidney (LYCK) cells. We found that the APS significantly inhibited H2O2-induced cytotoxicity, ROS accumulation, and mitochondrial damage, thereby alleviating subsequent apoptosis and pyroptosis. Further studies showed that APS activated the Keap1-Nrf2 antioxidant signaling pathway, thus up-regulating the downstream antioxidant genes (SOD-1, CAT, HO-1, and GR), enhancing SOD-1 and CAT activities and T-AOC level, and decreasing MDA content. Mechanistically, APS activate this antioxidant signaling pathway by inducing the expression of microRNA-183 (miR-183-5p). The produced miR-183-5p binds to the 3'UTR of Keap1 mRNA and promotes its degradation, leading to consequent Nrf2 activation. Our results therefore unveil the mechanism by which APS alleviate oxidative damage in a fish cell model, and provide the theoretical basis for their application in aquaculture.\n\nID: 42359357\nTitle: Innate immune crosstalk in ALS/FTD pathogenesis.\nAbstract: Marked by protein aggregation, impaired proteostasis, organelle stress, and chronic neuroinflammation, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) form a clinically, genetically, and pathologically overlapping disease spectrum. Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.\n\nID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\n\nID: 42351997\nTitle: Green-Extracted Ficus carica L. Fruit Polysaccharides Promote Longevity in Caenorhabditis elegans via Modulation of SKN-1 and IIS Pathway.\nAbstract: In this study, polysaccharides from Ficus carica L. fruits (FCPs) were extracted using a deep eutectic solvent (DES)-based ultrasound-assisted extraction (UAE) method. The physicochemical properties of the FCPs were then characterized, and the anti-aging effects of FCPs were evaluated in Caenorhabditis elegans (C. elegans). It was demonstrated that FCPs significantly extended the lifespan of the nematodes, while improving locomotor activity without affecting the body size or reproductive capacity. Meanwhile, FCPs reduced lipofuscin accumulation, decreased intracellular reactive oxygen species (ROS) levels, and increased the survival of C. elegans under oxidative stress. Moreover, FCPs upregulated the expression of antioxidant genes sod-1, sod-3, ctl-2, ctl-3 and gst-4. The expression of skinhead-1 (skn-1), a homologue gene of mammalian nuclear factor erythroid 2-related factor (Nrf) in C. elegans, was also elevated upon FCPs treatment. Knockdown of skn-1 expression by RNA interference abolished the lifespan extension and ROS reduction in FCPs-treated C. elegans, indicating that the SKN-1-mediated signaling was essential for the anti-aging effects of FCPs. Additionally, FCPs caused downregulation of the key components of the insulin/IGF-1 signaling (IIS) pathway, age-1, akt-1, and akt-2. Overall, these results suggested that FCPs promoted longevity in C. elegans via modulation of SKN-1 and IIS pathway.\n\nID: 42491970\nTitle: Discovery of novel indazole derivatives with anti-neuroinflammatory activity.\nAbstract: This study focuses on the critical role of microglia-mediated neuroinflammation in various neurological disorders. Utilizing the indazole heterocycle-a scaffold known for its structural plasticity and multi-target potential-as the core structure, a series of derivatives were designed and synthesized with the aim of screening and elucidating their anti-inflammatory activity and underlying mechanisms. The activities of the compounds were systematically evaluated in an in vitro LPS-stimulated BV-2 microglial model using Griess assay, MTT assay, qPCR, and western blotting. Among the 15 derivatives obtained, compound 5o exhibited the most potent anti-inflammatory activity (IC50 = 8.45 \u00b1 0.64 \u03bcM). Its mechanism of action involves the regulation of microglial polarization-significantly suppressing M1 phenotype markers such as NO, IL-1\u03b2, IL-6, TNF-\u03b1, iNOS, and COX-2. Further mechanistic studies revealed that this effect is mediated through positive regulation nuclear translocation of Nrf2. In summary, this study demonstrates that the indazole derivative 5o exerts anti-neuroinflammatory effects by inhibiting microglial M1 polarization, providing a promising lead compound and a robust pharmacological basis for the development of novel therapeutic strategies targeting neuroinflammatory diseases.\n\nID: 42491523\nTitle: Antibody screening identifies HERV-K-related immune responses as candidate biomarkers in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is increasingly recognized as a disorder involving both neurodegenerative and immune-related mechanisms. To explore potential immune alterations associated with PD, we analyzed plasma antibody responses against a panel of viral and host synthetic linear epitopes in PD patients (n = 50) and healthy controls (HCs) (n = 54). Antibody levels against Interferon Regulatory Factor 5 (IRF5), Cathepsin B (CTSB), L-asparaginase (ASRGL1), Human Endogenous Retrovirus type K (HERV-K), Interferon-\u03b1 (IFN-\u03b1), Interferon- \u03c9 (IFN-\u03c9), \u03b1-synuclein, Herpes Simplex Virus type 1 (HSV-1), olfactory receptor proteins (OLF-R), and Dickkopf-related protein 3 (DKK3) were measured. PD patients showed significantly higher antibody levels against IRF5, CTSB, ASRGL1, and HSV-1 compared with controls, while antibodies against HERV-K were significantly lower. No differences were observed for IFN-\u03b1, IFN-\u03c9, \u03b1-synuclein, OLF-R, or DKK3. Correlation analysis revealed several associations among antibody responses. IRF5 antibodies correlated positively with CTSB, ASRGL1, HERV-K, IFN-\u03b1, IFN-\u03c9, and HSV-1. CTSB correlated with IFN-\u03b1, IFN-\u03c9, HSV-1, OLF-R, and DKK3, while ASRGL1 correlated with HERV-K and IFN-\u03c9. IFN-\u03b1 correlated with IFN-\u03c9, HSV-1, and DKK3, and IFN-\u03c9 correlated with HSV-1 and DKK3. HSV-1 antibodies were also associated with OLF-R and DKK3. Notably, HERV-K antibodies showed a negative correlation with DKK3. Stratification analyses indicated that antibody levels against HERV-K were higher in patients with milder disease stages accordingly with Hoehn and Yahr scale (HY 1-4) compared with HY 5, whereas IFN-\u03b1 antibodies were increased in HY5 patients. Female patients generally showed lower antibody levels than males for different targets. No differences were observed according to disease duration. Overall, these findings indicate that PD patients display selective changes in antibody responses involving antiviral and host proteins. These targets may represent potential biomarkers of immune alterations in PD, although further studies are required to clarify the underlying biological mechanisms.\n\nID: 42491177\nTitle: From metabolism to genome integrity: NRF2 as a key mediator of cancer therapy response.\nAbstract: Metabolic rewiring in cancer is sustained by deregulated intracellular signaling, frequently due to genetic mutation of oncogenes, tumor suppressors or oncometabolite genes. These mutations strongly affect the activity of Transcription Factors (TFs) and epigenetic remodelling factors, ultimately leading to different metabolic subtypes. Of note, several metabolites have been proposed to significantly modulate gene expression through post-translational modifications of metabolic enzymes, TFs and histones, sustaining the intracellular feedback loop in cancer cells. Among the TFs involved in metabolic reprogramming of cancer cells, NRF2, a well-characterized factor in the oxidative stress response, emerged as a crucial player. NRF2 is at the crossroads of critical intracellular pathways linking metabolism, DNA damage and chromatin remodelling. These findings point to NRF2 as a pivotal player in cancer therapy resistance, making it a promising target to ameliorate patient survival. Remarkably, high expression and transcriptional activity of NRF2 have been demonstrated in several cancer types, where its expression and activity correlate with poor patient survival. Unfortunately, direct molecular targeting of TFs is still challenging. Therefore, identifying signaling pathways that either drive NRF2 deregulation or are sustained by its hyperactivation has emerged as an alternative strategy to enhance NRF2 targetability and ultimately improve therapeutic outcomes. Here, we aim to summarize the current knowledge on the role of NRF2 in resistance to cancer therapy, focusing on its regulation of gene expression, metabolism, and immune response in cancer, while exploring potential functional links between metabolic rewiring, chromatin remodelling and DNA damage response proficiency.\n\nID: 42491111\nTitle: Visual read performance of 18F-Florbetapir and 18F-NAV4694 A\u03b2 PET compared against Centiloid reference standard in a paired cohort.\nAbstract: Visual assessment remains standard practice to rule out amyloid-\u03b2 (A\u03b2) pathology. 18F-NAV4694 (NAV) has high affinity for A\u03b2 potentially detecting lower levels than other F-18 A\u03b2 tracers. One hundred fifty participants in the AIBL study underwent both 18F-Florbetapir (FBP) and NAV A\u03b2 PET scans. PET scans were assessed by six nuclear medicine physicians against Centiloid (CL) quantification. An optimized reference region was utilized for FBP as it improved CL-visual read correlations. Inter-reader agreement of visual assessment was measured using Fleiss' Kappa. Mean peak accuracy for visual read exceeded 95% for both NAV and FBP. However, peak accuracy for NAV visual reads was achieved at 14-15CL compared to 38-46CL for FBP. Higher inter-reader agreement was observed for NAV compared to FBP. For mild to moderate elevation in A\u03b2, visual read of NAV is more sensitive and consistent than visual read of FBP by both experienced and novice readers.\n\nID: 42490993\nTitle: Real-world pharmacovigilance for anti-A\u03b2 therapies using a large language model.\nAbstract: Anti-amyloid beta (A\u03b2) therapies for early Alzheimer's disease require enhanced safety monitoring, yet adverse event (AE) documentation is diffuse across heterogeneous electronic health record documents. Large language models (LLMs) may improve scalable pharmacovigilance. We analyzed 20,123 clinical documents from 46 patients who received at least one dose of anti-A\u03b2 therapy (June 24, 2024-July 30, 2025) at a large mid-Atlantic health-care system. We compared standard expert review versus an LLM-augmented workflow applied to the same documents. Expert reviewers annotated therapy-related AEs (e.g., amyloid-related imaging abnormalities with edema or hemorrhage, headache, syncope, hypersensitivity, gastrointestinal symptoms, infusion reactions). Discordant cases were adjudicated to establish a reference label. After adjudication, 76% (35/46) patients had an AE. The LLM-augmented workflow achieved 100% sensitivity (positive predictive value [PPV] 89.7%) versus expert review 88.6% sensitivity (PPV 100%). Findings provide preliminary indications that LLMs may serve as a pharmacovigilance signal detection tool, with a need for further validation and evaluation of clinical integration.\n\nID: 42489942\nTitle: From synaptic development to degeneration: a narrative review of small molecule strategies targeting alpha-synuclein in Parkinson's disease.\nAbstract: Aggregation of \u03b1-synuclein (\u03b1-Syn) is a defining pathological feature of Parkinson's disease (PD), contributing to progressive neuronal dysfunction and death. Unlike prior reviews focused predominantly on aggregation as an isolated endpoint, this review proposes a neurodevelopmental-neurodegenerative continuum as an interpretive framework, suggesting that \u03b1-Syn's physiological roles in synaptic development and circuit maturation may be linked to its later pathological behaviour. Within this context, we discuss recent advances in small-molecule strategies targeting key stages of \u03b1-Syn pathology, including synthesis, misfolding, aggregation, post-translational modification, and clearance. These include translation and misfolding inhibitors, aggregation modulators such as minzasolmin (UCB0599), epigallocatechin gallate and anle138b, as well as compounds that enhance \u03b1-Syn degradation through autophagy-lysosomal and ubiquitin-proteasome pathways. Additional strategies targeting proteostasis and mitochondrial dysfunction are also considered. Beyond its pathogenic role, \u03b1-Syn contributes to synaptic vesicle trafficking, neurotransmitter release, and neuronal maturation, and disruption of these functions may increase vulnerability to later neurodegeneration. In conclusion, small-molecule-based therapies represent a promising multi-targeted strategy for PD; however, key translational challenges and unresolved questions remain, including optimisation of pharmacokinetics, target specificity, and blood-brain barrier (BBB) penetration and validation in clinical settings.\n\nID: 42489794\nTitle: Combined Exposure to Polystyrene Nanoplastics and Gentamicin Promotes Liver Toxicity Through Oxidative Stress, Inflammation and Apoptotic Pathways: In Vivo and In Silico Studies.\nAbstract: Human exposure to nanoplastics and antibiotics is increasingly recognized as a major public health concern; however, the potential impacts of their combined exposure on human health remain poorly understood. In this study, we evaluated the hepatotoxic effects of polystyrene nanoplastics (PsNPs) and gentamicin (GEN), administered alone or in combination, and investigated the underlying molecular mechanisms using both in vivo and in silico approaches. Our findings demonstrated that co-exposure to PsNPs and GEN induces combined treatment response in liver by triggering oxidative stress, inflammation and apoptosis responses, associated with a dysregulation of genes related to oxidative stress (NRF2), inflammation (TNF-\u03b1, IL-1\u03b2), and apoptosis (Bax, Bcl-2, caspase-9, and caspase-3). Molecular docking analyses further supported these observations by revealing strong binding affinities of nanoplastics with key proteins involved in oxidative stress and inflammatory pathways. Our results revealed that co-exposure of adult rats to PsNPs and GEN induces an adverse effect on hepatic function. This study provides new evidence on the combined toxicity of polystyrene nanoplastics and pharmaceutical pollutants on liver function, suggesting a potential co-exposure-associated effect interaction between these contaminants.\n\nID: 42489719\nTitle: EPA-loaded silica nanoemulsions attenuate DEN-induced hepatic fibroinflammation by modulating homocysteine, PKC\u03b1/NF-\u03baB, and Nrf2 signaling.\nAbstract: Hepatic fibroinflammation is a progressive pathological process characterized by persistent inflammation, oxidative stress, and extracellular matrix deposition, ultimately leading to liver fibrosis. Alterations in membrane fatty acid composition, particularly the imbalance between pro-inflammatory arachidonic acid (AA) and anti-inflammatory eicosapentaenoic acid (EPA), contribute significantly to disease progression. Despite the anti-inflammatory properties of EPA are well established, its clinical application is limited by poor bioavailability. Therefore, this study investigated the therapeutic efficacy and molecular mechanisms of an EPA-loaded silica nanoemulsion (EPA-NE) in a diethylnitrosamine (DEN)-induced rat model of hepatic fibroinflammation. Thirty-two male Wistar albino rats were randomly allocated into four groups: control, DEN-induced hepatic fibroinflammation, DEN\u2009+\u2009EPA, and DEN\u2009+\u2009EPA-NE. Biochemical, molecular, histopathological, and bioinformatic analyses were performed to evaluate treatment outcomes. Both EPA and EPA-NE significantly restored membrane EPA/AA homeostasis, increasing the EPA/AA ratio, and attenuated hepatic injury. EPA and EPA-NE reduced serum homocysteine levels by 57.4% and 72.3%, respectively, and suppressed NF-\u03baB levels by 27.5% and 54.5%, respectively, compared with the DEN group (P\u2009<\u20090.0001). Moreover, EPA and EPA-NE enhanced antioxidant defenses, as evidenced by increased hepatic catalase activity by 1.7-fold and twofold, respectively, while reducing malondialdehyde levels by 23.1% and 46.2% (P\u2009<\u20090.0001), respectively. Molecular analyses demonstrated significant downregulation of PKC\u03b1 expression and upregulation of Nrf2 and miR-34a expression, indicating attenuation of inflammatory and oxidative stress pathways. Histopathological examination further confirmed the marked reduction of hepatic fibroinflammatory alterations following treatment, with EPA-NE exhibiting superior efficacy compared with EPA. In conclusion, EPA-loaded silica nanoemulsion effectively attenuated DEN-induced hepatic fibroinflammation, restored fatty acid homeostasis, reduced homocysteine levels, and modulated molecular markers associated with oxidative stress and inflammation. These findings suggest that nanoemulsion-based delivery enhances the biological activity of EPA and support the potential of EPA-NE as a promising therapeutic strategy for hepatic fibroinflammation.\n\nID: 42489714\nTitle: Mangiferin mitigates mercuric chloride-induced hepatotoxicity: targeting Nrf2, NF-\u03baB, NLRP3, and ER stress.\nAbstract: Mangiferin (Man), a xanthone glucoside, has been reported for its antioxidant, antiviral, anticancer, anti-inflammatory, and gene-regulatory properties. Mercuric chloride (HgCl2) is a toxic inorganic heavy metal compound that induces significant hematotoxic, hepatotoxic, neurotoxic, nephrotoxic, and genotoxic effects in biological systems. Therapeutic strategies targeting HgCl2-induced liver damage remain inadequately investigated. This study evaluated Man's protective effect against HgCl2-induced acute liver injury and the possible molecular mechanisms of hepatic protection effects in mice. Adult male BALB/c mice were administered two doses of Man (50 and 100 mg/kg, PO) 2 h before daily injections of HgCl2 (3 mg/kg, IP) for seven consecutive days. The results indicated Man's protective capabilities, as shown by marked improvement in hepatic histological abnormalities caused by HgCl2, along with the normalization of blood liver enzyme levels (ALT, AST, and LDH). These protective effects can be attributed to (i) cellular oxidative balance restoration via Nrf2 activation, TAC recovery, and NO and MDA reduction; (ii) suppression of pro-inflammatory signaling (NF-\u03baB, NLRP3, IL-1\u03b2, and Casp-1); (iii) apoptotic-proliferative homeostasis restoration via Bax downregulation and Bcl-2 upregulation; and (iv) endoplasmic reticulum stress attenuation (PERK and CHOP). In conclusion, Man could be considered as a potential protective agent against HgCl2-induced liver injury through controlling oxidative stress, inflammation, and apoptosis.\n\nID: 42489694\nTitle: Investigating the neurotoxic effects of NM-300K silver nanoparticles: in vitro and in vivo studies.\nAbstract: Silver nanoparticles (AgNPs) have gained widespread use in various applications, but their potential neurotoxic effects remain a concern. This study investigates the neurotoxicity of NM-300K AgNPs, which are Representative Manufactured Nanomaterials (RMNs), through in vitro assays using NG108-15 neuronal cells and in vivo experiments with BALB/c and Kunming mice. In vitro results showed an IC50 value of 100 \u00b5g mL-1 for NG108-15 cells, with a sub-lethal concentration of 25 \u00b5g mL-1 selected for further analysis. Proteomic analysis identified 96 significantly upregulated proteins, indicating activation of stress response pathways. Behavioral assessments revealed that mice exposed to 0.5 mg kg-1 day-1 AgNPs exhibited cognitive deficits, while those receiving 10 mg kg-1 day-1 displayed hyperactivity and increased anxiety-like behaviors. Histopathological examinations indicated neuronal vacuolation and loss in the CA3 region of the hippocampus, correlating with behavioral impairments. Biomarker analysis demonstrated significant oxidative stress, as evidenced by elevated reactive oxygen species (ROS) levels, increased interleukin-6, and increased Nrf2 levels. Exposure to high doses of AgNPs also led to reduced total antioxidant capacity (T-AOC), decreased glutathione (GSH), and elevated tumor necrosis factor-alpha (TNF-\u03b1), indicating an inflammatory response and activation of apoptotic pathways (caspase-3), suggesting that exposure to AgNPs can lead to neuronal dysfunction and cell death. These findings contribute to understanding the neurotoxic mechanisms of AgNPs, highlighting the need for thorough risk assessments and regulatory measures to mitigate potential health impacts associated with nanoparticle exposure.\n\nID: 42489527\nTitle: Elevated ferritin expression in microglia and extracellular amyloid-\u03b2 deposition are associated with reduced neurofibrillary degeneration in human isocortex, but not allocortex.\nAbstract: BackgroundPrior work in preclinical late-onset Alzheimer's disease (LOAD) focused on neuritic plaque development suggested that intracellular ferritin expression in microglia and extracellular deposition of amyloid-\u03b2 (A\u03b2) are innate neuroprotective mechanisms geared specifically towards limiting aging-dependent increases in intracerebral free iron which likely contribute to development of neurofibrillary degeneration (NFD).ObjectiveImprove understanding of LOAD pathogenesis.MethodsImmunohistochemical comparison of the extent of NFD with the intensity of ferritin expression and A\u03b2 deposition in three brain regions, including temporal lobe (entorhinal cortex, hippocampus), frontal, and occipital cortex in 34 non-demented human subjects at Braak stages II-III.ResultsFerritin-positive microglia are present with similar quantity and intensity in the allo- and isocortices of every individual in the cohort. Extracellular A\u03b2 deposition in the isocortex is observed before substantial NFD develops, but in the allocortex (temporal lobe) there are no A\u03b2 deposits in 50% of subjects despite extensive NFD. Cytoskeletal lesions in the allocortex consist of atrophic grid cells, abundant pretangles, neuropil threads, neurofibrillary tangles, and neuritic plaques; isocortical sites show either no NFD at all or only minimal NFD presenting as solitary pretangles or tangles, neuropil threads, or droplet degeneration spheres from ferroptotic neurons. Presence of degenerating grid neurons in entorhinal cortex coincides with microglial apoptosis.ConclusionsNeuroprotection via ferritin expression and A\u03b2 deposition is more effective in the isocortex than in allocortex. Findings support the hypothesis that degeneration or death of neuroprotective microglia promotes neuronal degeneration.\n\nID: 42489457\nTitle: Precuneus amyloid-\u03b2 deposition involving the association of irritability and cognitive decline: A multi-cohort longitudinal study.\nAbstract: BackgroundIrritability is increasingly recognized for its association with cognitive function, though its impact on cognitive decline and underlying mechanisms remain unclear.ObjectiveTo investigate the associations between irritability and cognition, identify potential neurobiological mechanisms.MethodsThis study included three cohorts: the Alzheimer's Disease Neuroimaging Initiative (ADNI, N\u2009=\u2009722), the UK Biobank (UKB, N\u2009=\u2009405,112), and the China Longitudinal Aging Study (CLAS, N\u2009=\u2009240). Participants were classified into irritability-positive (+) and irritability-negative (-) groups based on assessment of irritability.We used Linear mixed-effects models to assess irritability-related cognitive trajectory, Cox regression to estimate cognitive decline, mediation analysis to test the effect of amyloid-\u03b2 (A\u03b2) on the relationship between irritability and cognitive decline, and enrichment analysis to identify the underlying pathological mechanisms of irritability.ResultsIrritability was associated with increased cognitive decline in both ADNI (HR\u2009=\u20091.49, 95% CI: 1.12-1.98) and UKB (HR\u2009=\u20091.09, 95% CI: 1.04-1.15) cohorts, with baseline irritability linked to faster Mini-Mental State Examination decline (2.76 versus 1.88). Mediation analysis showed that cerebrospinal fluid (CSF) A\u03b2 mediated 19-24% of irritability's effect on cognitive decline, while precuneus A\u03b2 pathology mediated 30-41%. Imaging analysis revealed significant thinning of the left precuneus cortex in individuals with irritability. Proteomic analysis indicated underlying pathways involving enhanced energy metabolism and suppressed signal transduction, with modifiable factors (air pollution and physical inactivity) associated with irritability-related pathological proteins.ConclusionsOur findings indicate that irritability is significantly associated with cognitive decline. This association may be driven by mechanisms involving precuneus pathology, increased energy metabolism, and suppressed signal transduction, though these results warrant confirmation in future studies.\n\nID: 42489430\nTitle: Down syndrome-associated trisomic chromosomal regions modify amyloid-\u03b2 accumulation and cause early death in a mouse model of aspects of Alzheimer's disease.\nAbstract: BackgroundIndividuals with Down syndrome (DS), caused by triplication of chromosome 21 (Hsa21), face a significantly increased risk of early-onset Alzheimer's disease (AD) and epilepsy. However, the specific impact of Hsa21 genes on these risks is not yet fully understood.ObjectiveTo investigate how triplication of mouse chromosome 16 (Mmu16), homologous to Hsa21, affects amyloid-\u03b2 (A\u03b2) accumulation in the brain and epileptic seizures in AD-DS model mice.MethodsTo generate AD-DS model mice, we crossed a mouse model of aspects of AD-an APPswe/PS1dE9 mouse exhibiting brain A\u03b2 accumulation and sudden death associated with epileptic seizures with DS mouse models carrying an extra copy of partial segments of mouse chromosome 16. We used three DS model lines: Ts1Cje, harboring a triplicated region encoding \u223c70 Hsa21-homologous genes (Scaf4-Zbtb21); Ts1Rhr with triplication of the Cbr3-Fam3b region; and a newly developed Ts1Kei mouse carrying an extra copy of the Scaf4-Cbr1 region. A\u03b2 accumulation was assessed by immunohistochemistry and enzyme-linked immunosorbent assay.ResultsCompared with APPswe/PS1dE9 mice, A\u03b2 deposition and insoluble A\u03b2 levels in the brain decreased in APPswe/PS1dE9-Ts1Cje mice but not in APPswe/PS1dE9-Ts1Rhr mice. The high mortality in APPswe/PS1dE9 mice was suppressed by either Ts1Cje- or Ts1Rhr-triplicated region. Despite a tendency for decreased A\u03b2 accumulation in APPswe/PS1dE9-Ts1Kei mice, the study could not be finished due to the extremely high mortality.ConclusionsThe trisomic region in Ts1Kei mice is suggested to harbor genes associated with decreased A\u03b2 accumulation. Alternatively, the trisomic region in Ts1Rhr mice contains genes suppressing sudden death in APPswe/PS1dE9 mice.\n\nID: 42488940\nTitle: Yangxin Tongluo Decoction Protects Against Sepsis-Associated Cardiac Dysfunction Through Regulating Nrf2 Pathway.\nAbstract: Sepsis-induced cardiac dysfunction is a major cause of high mortality in critically ill patients. Yangxin Tongluo decoction (YXTLD), a traditional Chinese medicine (TCM) formula, is clinically used for such conditions, but its therapeutic effects and underlying mechanisms remain unclear. This study investigated the protective role of YXTLD against sepsis-associated cardiac dysfunction and its relationship with the Nrf2 signaling pathway. An in vivo model of sepsis was established in male C57BL/6 mice via intraperitoneal lipopolysaccharide (LPS) injection. Cardiac function was assessed by echocardiography and serum biomarkers (creatine kinase [CK], lactate dehydrogenase [LDH]). In vitro, LPS-stimulated H9c2 cardiomyocytes were treated with various doses of YXTLD. Cell viability, inflammation (interleukin [IL]-1\u03b2, IL-6, TNF-\u03b1), oxidative stress (reactive oxygen species [ROS], malondialdehyde [MDA], catalase [CAT], glutathione [GSH]), and apoptosis were evaluated. The involvement of the Nrf2 pathway was examined using western blotting. In vivo dosage: YXTLD was administered intraperitoneally five times prior to LPS induction and continued after induction (total of seven doses over 48\u2009h). In vitro concentrations: low (50 \u03bcg/mL), medium (100 \u03bcg/mL), and high (150 \u03bcg/mL) YXTLD. YXTLD significantly improved cardiac function and alleviated myocardial injury in septic mice, as evidenced by increased ejection fraction (EF; 97.87%\u2009\u00b1\u20091.20% vs. 79.05%\u2009\u00b1\u20093.04%) and fractional shortening (FS; 74.99%\u2009\u00b1\u20095.58% vs. 41.98%\u2009\u00b1\u20092.72%), together with reduced serum CK (188.60\u2009\u00b1\u200981.16 vs. 566.75\u2009\u00b1\u2009186.24\u2009U/L) and LDH (179.70\u2009\u00b1\u200954.47 vs. 463.65\u2009\u00b1\u2009197.58\u2009U/L) levels compared with the LPS group (all p\u2009 < 0.05). In LPS-stimulated H9c2 cells, YXTLD dose-dependently enhanced cell viability, suppressed the expression of pro-inflammatory cytokines (IL-6, IL-1\u03b2, and TNF-\u03b1), reduced ROS production and lipid peroxidation, restored antioxidant capacity, and inhibited apoptosis. At 50\u2009\u03bcg/mL, YXTLD markedly decreased IL-6, IL-1\u03b2, and TNF-\u03b1 levels by ~78%, 63%, and 92%, respectively (all p < 0.05). ROS and apoptotic cell proportions were progressively reduced with increasing YXTLD concentrations, reaching reductions of ~82% and 95%, respectively, at 150\u2009\u03bcg/mL (p < 0.001). Mechanistically, YXTLD activated the Nrf2 signaling pathway by promoting nuclear Nrf2 translocation and upregulating its downstream antioxidant proteins, including heme oxygenase-1 (HO-1), NAD(P)H quinone dehydrogenase 1 (NQO1), and glutamate-cysteine ligase modifier (GCLM). YXTLD also restored CAT and GSH levels while reducing MDA accumulation, indicating attenuation of oxidative stress. YXTLD protects against sepsis-induced cardiac dysfunction by attenuating inflammation, oxidative stress, and apoptosis through activation of the Nrf2 signaling pathway. These findings provide a pharmacological basis for YXTLD as a potential therapeutic strategy for sepsis-associated cardiac dysfunction.\n\nID: 42488833\nTitle: Huashi Baidu formula may attenuate adriamycin-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated ferroptosis.\nAbstract: Myocardial injury is a fatal adverse effect of adriamycin (ADR), which greatly limits its clinical application. Numerous studies have shown that Huashi Baidu formula (HBF) may exert a satisfactory effect on myocardial function repair. This study aims to reveal the underlying mechanisms and main bioactive compounds (BACs) of HBF against myocardial injury. Firstly, this study established an ADR-induced mouse model to assess the protective effects of HBF against myocardial injury. Subsequently, transcriptomic profiling was conducted to screen the differentially expressed genes among the HBF treatment, ADR-induced model, and normal control groups. Following the construction and analysis of protein-protein interactions, gene set enrichment analysis, and co-expression matrix, the key targets of HBF against myocardial injury were screened and further validated based on the ADR-induced mouse model. An integrative approach combining network mapping, molecular docking, and molecular dynamics simulation was performed to identify the representative BACs. Based on an ADR-induced myocardial injury mouse model, HBF significantly ameliorated myocardial injury by improving body weight loss, decreasing mortality, and rescuing severe cardiac fibrosis. A total of 361 ADR-related genes and 42 HBF therapeutic effect-related genes were identified with the thresholds P\u00a0<\u00a00.05 and fold change (FC)\u00a0>\u00a01.2 or\u00a0<\u00a00.833. Transcriptomic profiling-based networks demonstrated that the nuclear factor erythroid 2-related factor 2 (NRF2)-cyclic AMP-dependent transcription factor ATF-3 (ATF3)-sulfiredoxin-1 (SRXN1) axis-mediated ferroptosis was the key target of HBF against myocardial injury. In vivo validation showed that HBF treatment effectively inhibited serum enzymatic biomarkers of general myocardial injury (aspartate aminotransferase, lactate dehydrogenase, and creatine kinase), myofibroblast activity (transforming growth factor beta 1 and \u03b1-smooth muscle actin), inflammatory cytokines (tumor necrosis factor-\u03b1 and interleukin-6), oxidative damage (superoxide dismutase, malondialdehyde, accumulated iron content, and TUNEL-positive cells). Mechanically, HBF may restore the dysregulation of the NRF2-ATF3-SRXN1 signal axis, leading to inhibition of ferroptosis-associated protein expression. Emodin, rhein, and lactiflorin were identified as the underlying representative BACs of HBF against myocardial injury due to the strong binding affinities between candidate BACs and key targets [Kelch-like ECH-associated protein 1 (KEAP1), ATF3, SRXN1, system Xc- (SLC3A2/SLC7A11), glutathione peroxidase 4 (GPX4), ferroportin (FPN), glutathione synthetase (GSS)]. Molecular dynamics simulations further verified these findings, revealing the stable binding among the three components and the key targets. HBF may attenuate ADR-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated ferroptosis, and emodin, rhein, and lactiflorin are potential representative BACs.\n\nID: 42488829\nTitle: Challenges and opportunities for ginseng-based medicines in treating cardiac fibrosis from mechanistic insights to clinical translation.\nAbstract: Cardiac fibrosis, characterized by excessive extracellular matrix (ECM) deposition and progressive myocardial remodeling, is a common pathological outcome of various cardiovascular diseases and lacks effective targeted anti-fibrotic therapies. Panax ginseng and its related preparations, including major ginsenosides (e.g., Rb1, Rg1, and Rg3), standardized extracts, and compound formulas, have garnered growing interest owing to their multi-component, multi-target pharmacological activities and integrative regulatory effects. This review systematically summarizes recent advances in the basic and clinical research of ginseng-based medicines in the prevention and treatment of cardiac fibrosis. Preclinical evidence demonstrates that ginseng and its active constituents attenuate key pathological processes, including oxidative stress, inflammatory responses, apoptosis, and autophagy dysregulation, primarily through modulation of signaling pathways such as TGF-\u03b2/Smad, NF-\u03baB, and PI3K/Akt. These regulatory effects collectively contribute to the inhibition of fibroblast activation, reduction of collagen deposition, and improvement of myocardial structure and function. Emerging clinical studies further suggested potential benefits in improving cardiac function and modulating fibrosis-related biomarkers in patients with hypertension, coronary heart disease, and heart failure (HF). Despite these promising findings, several challenges hinder clinical translation, including low oral bioavailability, the mechanistic complexity of compound formulas, and insufficient high-quality clinical evidence. Future investigations should integrate novel drug delivery strategies, systems pharmacology approaches to elucidate holistic mechanisms, and well-designed randomized controlled trials to facilitate the development of ginseng-based medicines as potential therapeutic agents for cardiac fibrosis.\n\nID: 42488758\nTitle: Substantia Nigra MRI markers are lower in Alzheimer's disease and are linked to general cognitive function.\nAbstract: Individuals with Alzheimer's disease dementia show Alzheimer's disease pathology and a heterogeneous degeneration of the Substantia Nigra (SN) post-mortem. However, it is unclear how SN degeneration is related to cognitive dysfunction across the Alzheimer's disease dementia continuum. In this study, using data from the prospective DZNE-Longitudinal Cognitive Impairment and Dementia Study (DELCODE), we investigated whether in vivo SN MRI measures are lower in individuals with clinically defined Alzheimer's disease dementia than in healthy control subjects (HC) and if they are associated with hippocampal functional activity during the processing of novel visual stimuli and subsequent recognition memory. One hundred and sixty DELCODE participants (69\u2005years \u00b1 6\u2005years, 88 men), including 79 HC, 70 individuals with subjective cognitive decline (SCD), 17 individuals with mild cognitive impairment (MCI) and 10 individuals with Alzheimer's disease dementia, completed a scene novelty and encoding task and a 3T SN-sensitive MRI scan, from which the two in vivo SN measures MRI contrast and volume were calculated and harmonized between scanner sites while preserving diagnostic group differences. For 71 individuals, CSF levels of phosphoTau, total tau and amyloid-beta 42/40 ratio (A\u00df42/40) were available. All individuals completed a neuropsychological task battery from which a global cognitive score was calculated. In separate models, we assessed the relationship between SN MRI markers and CSF levels of Alzheimer's disease, the global cognitive score, hippocampal novelty activation and recognition memory while accounting for age, sex, years of education and total intracranial volume (TIV). SN volume but not SN MRI contrast was lower in individuals with clinical Alzheimer's disease dementia [one-way analyses of covariance (ANCOVA); F(156,4) = 5.6665, P = 0.0010, n = 160]. SN MRI contrast and volume were not associated with A\u00df42/40, ptau and total tau CSF levels (all P > 0.1) or hippocampal novelty activation (all P > 0.1). Moreover, SN volume was positively associated with recognition memory (R 2 = 0.07, P < 0.001, n = 159), global cognition (R 2= 0.38, P < 0.0001, n = 160) and years of education (R 2 = 0.03, P = 0.036, n = 160). Our study emphasizes the potential of using in vivo SN MRI markers to study the impact of SN degeneration on general cognitive impairment and recognition memory in an Alzheimer's disease dementia cohort. Our results motivate future longitudinal studies to explore how SN volume and SN contrast change with disease progression, how these are differentially associated with cognitive decline, and how SN volume and SN contrast might be related to other dopamine-dependent cognitive functions and dysfunctions.\n\nID: 42488725\nTitle: Prenatal and neonatal housing conditions affect anxiety-like behavior in adulthood in rats and interact with brain-derived neurotrophic factor (BDNF) Val66Met to alter expression of BDNF and stress markers in the ventral hippocampus.\nAbstract: We investigated the interaction of the brain-derived neurotrophic factor (BDNF) gene variant, Val66Met, with the effect of prenatal/neonatal environmental conditions on anxiety-like behavior in adulthood in rats. In a genetic Val66Met rat model, we compared the effects of a high-enrichment/high-complexity early-life environment (HE) and a low-enrichment/low-complexity environment (LE). Body weight was higher in both male and female HE rats compared to LE rats. Anxiety-like behavior on a plus maze or in an open field was enhanced in both male and female HE rats compared to LE rats. In contrast, following HE, only in females, adrenal weight was higher, and in the forced swim test, immobility was lower, and swimming was higher. Body weight and behavioral changes did not differ between BDNF genotypes. Fear conditioning and extinction were not affected. The effect of HE vs. LE condition on expression of BDNF, the antioxidant transcription factor, NRF2, and the glucocorticoid receptor, NR3C1, in the ventral hippocampus varied depending on genotype, and most of these changes were again only seen in females. There were no effects on the expression of the stress markers, SGK1 and FKBP5, or the mineralocorticoid receptor, NR3C2. These results show persistent effects of early-life environment on anxiety-like behavior and gene expression of BDNF and stress markers in adulthood, with some effects showing sex- and Val66Met genotype specificity. These results may be important for our understanding of factors involved in the development of clinical anxiety and depression, and also have implications for animal welfare in the laboratory setting.\n\nID: 42488724\nTitle: BDNF-amyloid-\u03b2 Axis in Alzheimer's disease: molecular mechanisms and therapeutic perspectives.\nAbstract: Alzheimer's disease (AD), the most common cause of dementia in older adults, is characterized by progressive cognitive decline, synaptic dysfunction, and neuronal loss. Among the multifactorial mechanisms implicated in AD, reciprocal interactions between brain-derived neurotrophic factor (BDNF) and amyloid-\u03b2 (A\u03b2) have attracted increasing attention as a convergent axis linking amyloid pathology to impaired neurotrophic support. BDNF promotes neuronal resilience, synaptic plasticity, and cognitive function primarily through the activation of its high-affinity receptor, tropomyosin receptor kinase B (TrkB), and downstream signaling pathways, including PI3K-Akt and MAPK/ERK. Human postmortem and biomarker studies mainly support associations between reduced BDNF signaling, synaptic dysfunction, and AD-related pathology. In contrast, cell-based and animal studies provide mechanistic evidence that BDNF/TrkB signaling may influence amyloid precursor protein (APP) processing and neuronal resistance to A\u03b2-induced stress. Conversely, mechanistic studies indicate that A\u03b2 accumulation can suppress CREB-dependent BDNF expression, disturb BDNF transport, and impair TrkB receptor function. Thus, the BDNF-A\u03b2 relationship is better interpreted as a stage- and context-dependent pathogenic coupling rather than a simple causal loop. This review synthesizes evidence from human studies, animal models, and cellular systems to clarify how BDNF-A\u03b2 dysregulation contributes to AD progression and to discuss the translational potential of BDNF-oriented interventions.\n\nID: 42488639\nTitle: Autoimmune signatures in neurodegenerative dementias: from peripheral immune activation to CNS pathology.\nAbstract: Neurodegenerative dementias, including Alzheimer's disease, Parkinson's disease dementia, dementia with Lewy bodies, and related tauopathies, are traditionally defined by protein aggregation, neuronal dysfunction, synaptic loss, and glial-mediated neuroinflammation. However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses.\n\nID: 42488570\nTitle: The protective efficacy of baricitinib against lipopolysaccharide / D-Galactosamine-Induced acute liver Injury.\nAbstract: Baricitinib (BARI), the selective JAK1/JAK2 inhibitor demonstrates enhanced immunological activity against several inflammatory conditions. Given the complex, multiple pathogeneses of acute liver inflammatory injury (ALIs), this study investigates BARI in a non-sterile murine model of fulminant hepatic failure to address existing management gaps. Mice were exposed to a toxic challenge with a single dose of lipopolysaccharide (LPS, 80 \u03bcg/kg, ip) and D-galactosamine (D-GaIN, 800 mg/kg, ip) on day 3. BARI (10 and 20 mg/kg, po) were administered prophylactically from day 1 to day 3 with the last dose of BARI given 2 h before LPS/D-GaIN. Investigations revealed substantial lowering in liver function indices in BARI-treated groups after the pathogenic elevation in the LPS/D-GaIN group. These results coincided with remarkable reduction of necrosis and an improvement of hepatic architecture identified by the H&E staining in the BARI-treated groups compared to the disrupted histological features with substantial infiltration of inflammatory cells. The inflammatory cells observed in the LPS/ D-GaIN group represent a major source of ROS that contributes to nitrosative stress via the respiratory burst (NO), peroxidation of the PUFA of the cell membrane (MDA), and consumption of the cellular antioxidant molecules (TAC). This oxidative condition was reversed in BARI groups together with reestablishment of the antioxidant axis of Nrf2/HO-1 showing a remarkable capacity to restore redox equilibrium. The observed ameliorative potential of BARI is probably attributed to inhibition of IL-6 transcription, as confirmed by the inhibited activation of the transcription factor NF-\u03baB, with subsequent inhibition of JAK2/STAT3. While curbing apoptosis as evidenced by reduced levels of cleaved caspase-3, BARI presented its ability to preserve the level of PI3K/AKT/ mTOR signaling. These findings highlight the protective capacity of BARI and its value for repurpose in medical management of acute liver failure.\n\nID: 42487594\nTitle: Targeting A\u03b225-35-Induced Neuronal Senescence-Like Features Using Curcumin-Loaded Solid Self-Emulsifying Drug Delivery Systems.\nAbstract: Curcumin is widely recognized for its anti-neurodegenerative properties. However, its clinical utility is hindered by poor aqueous solubility and low bioavailability. To address these limitations, Curcumin-loaded Solid Self-Emulsifying Drug Delivery Systems (C-SSEDDS) have been formulated to improve pharmacokinetics and neuronal targeting. Despite these advancements, the molecular mechanisms underlying curcumin in Alzheimer's Disease (AD)-related neuronal senescence remain poorly understood. Therefore, this study provides novel molecular insights into the therapeutic potential of C-SSEDDS for targeting neuronal senescence- like features in the AD context. An in vitro model of neuronal senescence-like features was established by exposing SK-N-SH cells to 0.075 \u03bcM A\u03b225-35 for 24 hours, resulting in a 20-30% decline in cell viability. Subsequently, cells were post-treated with C-SSEDDS at optimized non-toxic concentrations (0.1, 1, and 10 \u03bcg/mL curcumin equivalent) and 10 \u03bcg/mL commercial curcumin for 24, 48, and 72 hours in A\u03b225-35-free media. The study comprehensively assessed cell viability, morphological alterations, and key biomarkers associated with neuronal senescence-like features, including senescence- associated beta-galactosidase (SA-\u03b2-gal) positive cells, Reactive Oxygen Species (ROS) levels, NLRP3, Sirt-1, and synaptophysin expression. C-SSEDDS post-treatment significantly improved cell viability, reduced apoptotic cells, and decreased SA-\u03b2-gal positive cells in A\u03b225-35-induced senescence-like SK-N-SH cells compared to the untreated A\u03b225-35 group. It also effectively decreased intracellular ROS level and NLRP3 expression, and markedly upregulated Sirt-1 and synaptophysin expression. Notably, CSSEDDS demonstrated therapeutic efficacy superior to commercial curcumin and comparable to N-acetylcysteine (NAC). In SK-N-SH cells exhibiting senescence-like features, the C-SSEDDS formulation effectively counteracts A\u03b225-35-induced damage. It mitigates key drivers of cellular stress, including oxidative stress, inflammation-related markers, and apoptosis, while also enhancing Sirt-1 activity and promoting synaptic plasticity. C-SSEDDS demonstrates significant potential as a promising therapeutic strategy against A\u03b225-35 -induced neuronal stress and senescence-like changes in AD.\n\nID: 42487586\nTitle: Naotaifang Formula Suppresses Ferroptosis by Ameliorating Mitochondrial Biogenesis Through the Nrf2/TFAM Pathway in Ischemic Stroke.\nAbstract: This study aimed to investigate whether activating the Nrf2/TFAM pathway boosts mitochondrial biogenesis, reduces ferroptosis in ischemic stroke (IS), and evaluates Naotaifang (NTF) formula's therapeutic potential. Ferroptosis and mitochondrial biogenesis indicators were measured at various time points following MCAO. Various methods, including transmission electron microscopy, immunofluorescence assay, enzyme-linked immunosorbent assay, Western blotting assays, and real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR), were employed to evaluate the impact of NTF on mitochondrial biogenesis and ferroptosis in vivo and in vitro. IS significantly inhibits mitochondrial biogenesis and increases neuronal ferroptosis, with brain damage worsening over time. MCAO groups showed reduced expression of Nrf2, TFAM, ATP, CISD2, FPN, GPX4, SOD, and HO-1, alongside elevated Fe\u00b2\u207a, ROS, and LPO (P < 0.05) compared to the control group. Both sulforaphane and NTF treatment reversed these effects; NTF treatment effectively increased the expression of Nrf2, TFAM, FtMt, CISD1, CISD2, FPN, and GPX4 while inhibiting the levels of Fe2+, ROS, and LPO. (P < 0.05). This finding clarifies mitochondrial biogenesis's crucial role, proposes a new \"pathway + molecule\" strategy for IS treatment, and supports NTF's clinical potential, though larger animal models and long-term safety studies are needed. In the context of IS, reduced mitochondrial biogenesis plays an important role in ferroptosis. Targeting the Nrf2/TFAM signaling pathway may improve mitochondrial biogenesis in IS. Furthermore, NTF can mitigate ferroptosis by promoting mitochondrial biogenesis through the Nrf2/TFAM signaling pathway.\n\nID: 42487541\nTitle: Characterization, Analysis, and Alleviating Effects of Sulfated Polysaccharides Derived From Agardhiella subulata on Di-(2-Ethylhexyl) Phthalate-Induced Testicular Toxicity in Mice.\nAbstract: Exposure to di-(2-ethylhexyl) phthalate (DEHP) adversely affects the reproductive system. Agardhiella subulata extracts are known for their antioxidant and hepatoprotective properties, yet their effects against DEHP-induced testicular toxicity remain unclear. This study investigated the extraction, characterization, and protective effects of A. subulata sulfated polysaccharide (ASP) against DEHP-induced testicular damage. Autoclave-assisted extraction yielded 40.4% ASP. Chemical and structural characterization using HPLC and NMR identified ASP as a sulfated carrageenan predominantly composed of \u03b2-Gal4S and DA2S, with minor impurities. In mice exposed to DEHP (200\u00a0mg/kg/day) for 10 weeks, ASP treatment (50 or 200\u00a0mg/kg/day via oral gavage) significantly improved testicular weight, sperm count, and motility, while alleviating seminiferous tubule atrophy and germinal epithelium degeneration. ASP attenuated oxidative stress by normalizing MDA, SOD, and GSH levels. Mechanistically, ASP activated the Nrf2/HO-1 antioxidant signaling pathway, suppressed caspase-3 and caspase-8 expression, reduced inflammation, and enhanced steroidogenesis by increasing stAR and 3\u03b2-HSD expression and serum testosterone levels. Overall, these findings demonstrate that ASP effectively mitigated DEHP-induced testicular toxicity through antioxidant, anti-apoptotic, anti-inflammatory, and steroidogenic mechanisms. These findings suggest that ASP is a promising natural agent for protecting against DEHP-induced reproductive toxicity and improving testicular function. Thereby supporting SDG goals 3, 12, and 15.\n\nID: 42487538\nTitle: Epigenetically Regulated NOX4/NRF2 Axis Mediates PM2.5-Induced Ferroptosis and Inflammatory Response in Membranous Nephropathy.\nAbstract: This study aims to explore the involvement and mechanism of ferroptosis in particulate matter 2.5 (PM2.5)-induced membranous nephropathy (MN) progression. A cationic bovine serum albumin (cBSA)-induced mouse model of MN was established, followed by PM2.5 exposure. Renal injury was assessed using hematological indicators, hematoxylin-eosin staining, and periodic acid-Schiff staining. Levels of inflammatory factors and ferroptosis indicators were assessed by enzyme-linked immunosorbent assay and western blot. An in\u00a0vitro MN-like model was created by stimulating differentiated MPC5 podocytes with puromycin aminonucleoside (PAN), followed by PM2.5 treatment. DNA methylation levels were determined using quantitative methylation-specific polymerase chain reaction. Podocytes were pretreated with GKT137831 or ferrostatin-1 for in\u00a0vitro rescue experiments. PM2.5 exposure significantly aggravated renal injury in cBSA-induced MN mice, as indicated by increased levels of urinary total protein, serum creatinine, and blood urea nitrogen; the deposition of IgG and C3; and histopathological alterations. Furthermore, PM2.5 increased levels of ferroptosis and inflammation in the renal tissues of cBSA-induced MN mice, accompanied by the activation of the NOX4/NRF2 axis. In PAN and PM2.5 co-treated MPC5 cells, NOX4 expression was elevated, whereas its methylation level was reduced. Overexpression of DNMT1 reversed the PM2.5-induced suppression of NOX4 methylation. Notably, pretreatment with GKT137831 or ferrostatin-1 attenuated the PM2.5-mediated reduction in cell viability and prevented the activation of ferroptosis and pro-inflammatory phenotypes in PAN-stimulated MPC5 cells. In conclusion, PM2.5 promotes ferroptosis and inflammation through an epigenetically regulated NOX4/NRF2 axis, thereby exacerbating renal injury in MN.\n\nID: 42487470\nTitle: MiR-199a-5p aggravates hypoxia/reoxygenation-induced cardiomyocyte ferroptosis by blocking HSPB1-Keap1/Nrf2/ARE signaling.\nAbstract: Ferroptosis plays a crucial role in hypoxia/reoxygenation (H/R)-induced cardiomyocyte injury and acute myocardial infarction (AMI), yet the involvement of microRNA-199a-5p (miR-199a-5p) in this process remains insufficiently understood. In this study, serum miR-199a-5p levels were markedly elevated in AMI patients and positively correlated with myocardial injury markers cardiac troponin I and creatine kinase-MB, while H/R stimulation similarly upregulated miR-199a-5p expression in AC16 cardiomyocytes. Functional experiments demonstrated that miR-199a-5p overexpression exacerbated oxidative stress and ferroptosis, as evidenced by increased lactate dehydrogenase release, malondialdehyde production, Fe\u00b2+ accumulation, lipid peroxidation, and glutathione depletion, whereas miR-199a-5p inhibition conferred significant protection against H/R-induced injury. Mechanistically, heat shock protein \u03b2\u20111 (HSPB1) was identified as a direct downstream target of miR-199a-5p, with HSPB1 overexpression alleviating and its silencing aggravating ferroptotic responses under H/R conditions. Rescue assays further confirmed that HSPB1 mediates the pro-ferroptotic effects of miR-199a-5p. At the molecular level, the miR-199a-5p/HSPB1 axis regulated key ferroptosis-related proteins, including ACSL4, SLC7A11, and GPX4, and disrupted Keap1/Nrf2/ARE antioxidant signaling during H/R injury. Collectively, these findings indicate that miR-199a-5p aggravates H/R-induced cardiomyocyte ferroptosis by suppressing HSPB1 and impairing Nrf2-dependent antioxidant defense, suggesting that circulating miR-199a-5p may serve as a biomarker of myocardial injury and a potential therapeutic target in ischemic heart disease.\n\nID: 42487434\nTitle: Reframing welders' parkinsonism: from the \"idiopathic\" label to biological causation and legal recognition.\nAbstract: In Korea, welders diagnosed with \"idiopathic Parkinson's disease (iPD)\" often face denial of workers' compensation, as \"idiopathic\" is interpreted as excluding occupational contribution. This narrative review examines whether a categorical distinction between iPD and \"toxic parkinsonism\" is defensible on diagnostic, pathological, neuroimaging, epidemiological, causal-inference, and legal grounds. The 2024 NSD-ISS (Neuronal \u03b1-synuclein disease Integrated Staging System) and SynNeurGe (Synuclein-Neurodegeneration-Gene) frameworks challenge categorical use of the \"idiopathic\" label by defining Parkinson's disease (PD)-related disease biologically, irrespective of etiology. Nonhuman primate studies show that chronic low-dose manganese exposure can produce nigrostriatal deficits and \u03b1-synuclein aggregation overlapping with PD biology. Dichotomous use of FP-CIT dopamine transporter imaging or levodopa responsiveness to separate manganese poisoning from iPD is therefore scientifically unsound, as chronic welding exposure can induce presynaptic dysfunction and treatment responses indistinguishable from PD. Epidemiological findings diverge methodologically: direct clinical examination has reported elevated parkinsonism prevalence among welders, whereas administrative cohorts have generally found no increased PD risk. This divergence is plausibly explained by differences in case ascertainment, exposure assessment, healthy-worker-survivor selection, and disease latency. Bradford Hill and Rothman frameworks support a causal interpretation, although validated biomarkers and dose-response thresholds remain undefined. Under Korea's Industrial Accident Compensation Insurance Act, causation is evaluated as a \"proximate causal relationship\" rather than strict scientific proof. A multi-hit model integrating genetic predisposition, aging, and cumulative environmental exposure supports recognition under this standard, and compensation eligibility should not depend on whether the diagnosis label is 'PD' or 'parkinsonism.' When parkinsonian symptoms occur in welders with at least approximately 20,000 exposure-weighted welding hours, or with substantial high-intensity exposure such as confined-space welding, inadequate ventilation, or flux-cored arc welding, occupational contribution should be considered under a weight-of-evidence approach. This criterion is sufficient for recognition but is not a necessary condition.\n\nID: 42487291\nTitle: Yougui Pills Alleviate Osteoporosis by Inhibiting Mesenchymal Stem Cell ROS Accumulation via the Nrf2/HO-1 Pathway.\nAbstract: Osteoporosis (OP) is a prevalent skeletal disorder characterized by progressive bone mass loss and deteriorated microarchitecture, in which oxidative stress-induced mesenchymal stem cell (MSC) dysfunction serves as a core pathogenic mechanism. Yougui Pills (YGPs), a classical traditional Chinese medicine formula, are widely applied in clinical OP management, yet the cellular and molecular mechanisms underlying their anti-osteoporotic effects remain incompletely defined. This study aimed to elucidate the bone-protective role of YGPs in OP and explore the underlying mechanism, focusing on oxidative stress modulation in MSCs and the Nrf2/HO-1 signalling pathway. The bioactive components of YGPs and YGP-containing serum were characterized via UPLC. In vivo, an ovariectomy (OVX) mouse model was established to evaluate YGPs' effects on bone mass, trabecular microstructure and osteogenesis using micro-CT, histological and immunohistochemical assays; public GEO datasets were re-analysed to profile transcriptomic alterations and oxidative stress signatures in OP-derived MSCs. In vitro, H2O2 was used to induce ROS accumulation and oxidative injury in MSCs, with assessments of cell proliferation, apoptosis, ROS levels, migration and osteogenic differentiation. Network pharmacology and siRNA-mediated gene silencing were conducted for target prediction and mechanistic validation. In vivo results showed that YGP treatment significantly ameliorated OVX-induced osteopenia, increased bone mineral density, improved trabecular microstructure, and upregulated osteogenic markers (ALP, OCN, Runx2, COL1A1). Transcriptomic re-analysis revealed upregulated oxidative stress markers in OP MSCs, consistent with In vitro findings that YGPs attenuated H2O2-triggered ROS overproduction, suppressed apoptosis and ectopic lipid deposition, and enhanced MSC proliferation, migration and osteogenic differentiation. Mechanistically, YGPs activated the Nrf2/HO-1 signalling axis, while Nrf2 knockdown abrogated YGPs' cytoprotective and pro-osteogenic effects. In conclusion, YGPs mitigate oxidative stress-induced MSC dysfunction and promote osteogenesis via the Nrf2/HO-1 pathway, supporting YGPs as a promising therapeutic candidate for OP.\n\nID: 42487262\nTitle: Effects of cold water immersion versus active recovery on oxidative stress, redox gene expression and mitochondrial adaptations after strength training.\nAbstract: We compared the acute and chronic effects of postexercise cold water immersion (CWI) and active recovery (ACT) on oxidative stress, redox-related gene expression, mitochondrial adaptations and muscle oxidative capacity. In a crossover study, nine males completed strength sessions, followed by either 10\u00a0min CWI or ACT. There were time effects for blood oxidative stress markers, including serum derivatives of reactive oxygen metabolites and serum biological antioxidant potential (P\u00a0<\u00a00.05). F2-Isoprostanes were lower after exercise in the CWI trial compared with the ACT trial (P\u00a0<\u00a00.05), whereas plasma glutathione peroxidase activity was higher in the CWI trial at 2\u00a0h after exercise (P\u00a0<\u00a00.05). There were time effects for redox-related genes, including NRF2, SXRN, HMOX1, GCLM, TP53 and TXN, in muscle after exercise (P\u00a0<\u00a00.05). Postexercise gene expression did not differ between the CWI and ACT trials. In a parallel-group study, 21 males strength-trained twice a week for 3 months and performed either 10\u00a0min CWI or ACT after each session. There were time effects for the activity of citrate synthase and mitochondrial enzyme complexes I and IV (P\u00a0<\u00a00.05) and the protein abundance of p-AMPK (P\u00a0<\u00a00.05) in muscle after training. These responses did not differ between the CWI and ACT groups. Evaluation of muscle oxidative capacity using near-infrared spectroscopy showed slower oxygen desaturation during a 10\u00a0s isometric contraction, and greater oxygen consumption during 50 isokinetic contractions after training in the CWI group (P\u00a0<\u00a00.05). In conclusion, CWI after resistance exercise does not alter acute redox-related transcription or chronic mitochondrial adaptations, whereas it might improve muscle oxygen kinetics.\n\nID: 42487073\nTitle: Immunomodulatory effects of ultrasonically lysed Bifidobacterium breve on Pam3CSK4-stimulated J774A.1 macrophages via SIRT1/NRF2 activation and NF-\u03baB suppression.\nAbstract: Bacterial lysates, which contain cell wall components and intracellular metabolites, have emerged as important modulators of macrophage immune function through interactions with pattern recognition receptors (PRRs). Ultrasonication is an effective technique for extracting these bioactive constituents. The goal of this work was to examine the immunomodulatory and cytoprotective effects of ultrasonically lysed Bifidobacterium breve (BB-UL) in J774A.1 macrophages activated by Pam3CSK4. J774A.1 macrophages were pre-exposed to BB-UL (equivalent to 10\u2078 CFU/mL) for 12\u00a0h before stimulation with Pam3CSK4 (500 ng/mL). Cell viability was determined via the MTT assay, intracellular reactive oxygen species (ROS) were quantified using the DCFDA assay, and apoptosis was assessed with Annexin V-FITC/PI staining. Gene expression levels of Sirt1, Nfe2l2, Hmox1, Rela, Il1b, Il6, Tnf, Bax, and Bcl2 were analyzed by RT-qPCR, while secreted cytokines were measured using ELISA. Statistical significance was evaluated using one-way ANOVA followed by Tukey's post hoc test (n\u2009=\u20093). Pam3CSK4 exposure significantly decreased cell viability to approximately 50% of control levels, whereas BB-UL pretreatment restored viability to around 80-85% (p\u2009<\u20090.01 vs. Pam3CSK4), indicating a protective effect. Pam3CSK4 also induced a substantial increase in intracellular ROS (~\u20093-fold vs. control), which was reduced by approximately 40% following BB-UL treatment (p\u2009<\u20090.05-0.01). Similarly, late apoptosis increased from ~\u20093-4% in control cells to ~\u200915% upon stimulation, while BB-UL pretreatment decreased this value to approximately 8% (p\u2009<\u20090.01). At the molecular level, Pam3CSK4 downregulated Sirt1 (~\u20090.5-fold) and Nfe2l2 (~\u20090.55-fold), while upregulating Rela (~\u20092.5-fold). BB-UL partially restored Sirt1 (~\u20090.7-fold) and Nfe2l2 (~\u20090.75-fold) expression and reduced NF-\u03baB activation (~\u20091.8-fold vs. control, p\u2009<\u20090.05). Additionally, BB-UL increased Hmox1 expression (~\u20090.9-fold) and favorably regulated apoptosis-related genes by decreasing Bax (~\u20091.5-fold) and increasing Bcl2 (~\u20090.8-fold), thereby improving the Bax/Bcl2 ratio. Following BB-UL pretreatment, elevated levels of pro-inflammatory cytokines (Il1b, Il6, and Tnf) caused by Pam3CSK4 were considerably decreased at both gene and protein levels (p\u2009<\u20090.05-0.01). In Pam3CSK4-stimulated macrophages, ultrasonically lysed B. breve had notable cytoprotective, antioxidant, and anti-inflammatory properties. Reduced oxidative stress, apoptosis, and inflammatory cytokine production were associated with modulation of SIRT1, NRF2, HO-1, and NF-\u03baB-related gene expression. These findings suggest that BB-UL may represent a promising postbiotic candidate for modulating macrophage-mediated inflammatory responses.\n\nID: 42487045\nTitle: BMSC-derived exosomal METTL3 synergizes with Sevoflurane to inhibit ferroptosis in pulmonary ischemia/reperfusion injury by enhancing USP7 N6-methyladenosine modification.\nAbstract: Inhibition of ferroptosis was shown to alleviate pulmonary ischemia/reperfusion (I/R) injury. This study aimed to investigate the synergistic effects of bone marrow mesenchymal stem cells (BMSC)-derived exosomal METTL3 and Sevoflurane (Sev) in alleviating pulmonary I/R injury through ferroptosis regulation. In our study, pulmonary I/R injury models were established in mice and lung microvascular endothelial cells (LMECs). Commercial kits were used to measure myeloperoxidase (MPO), glutathione (GSH), malondialdehyde (MDA), and iron content. Lipid peroxidation was determined using the BODIPY 581/591 C11 probe by flow cytometry. Total m6A modification was measured by the commercial kit and m6A dot blot, while m6A modification of USP7 mRNA was analyzed by MeRIP and polysome profiling. The interaction between proteins or RNAs was analyzed by Co-IP, FISH combined with immunofluorescence, RNA pull-down, RIP, or dual-luciferase reporter assay. We proved Sev preconditioning mitigated ferroptosis in pulmonary I/R injury by activating the Nrf2 pathway. Co-treatment with BMSC-derived exosomes potentiated the protective effects of Sev by promoting USP7-mediated Nrf2 deubiquitination modification. Mechanistically, BMSC-derived exosomal METTL3 promoted USP7 mRNA translation through YTHDC2-dependent m6A modification. Also, METTL3 knockdown in exosomes suppressed the Nrf2 pathway and exacerbated ferroptosis, while METTL3 overexpression showed opposite effects. YTHDC2 knockdown abolished these protective effects caused by METTL3-overexpressed exosomes. In conclusion, BMSC-derived exosomal METTL3 reinforced the protective effects of Sev by promoting USP7 mRNA translation via YTHDC2-dependent m6A modification. Upregulated USP7 subsequently facilitated Nrf2 deubiquitination, thereby inhibiting ferroptosis and protecting against pulmonary I/R injury.\n\nID: 42486877\nTitle: Adaptive pathways for multimodal community-based detection of cognitive impairment: the CogScreen I study.\nAbstract: Early detection of cognitive impairment is essential for dementia prevention and timely care. However, implementation in primary care and community settings remains limited. Building dementia-prepared health systems requires scalable and adaptive pathways that integrate subjective, digital and biological indicators, while accounting for heterogeneity in risk,\u00a0education and age. CogScreen I was a cluster-randomized trial conducted in Munich senior centers from March 2023 to March 2024. Recruitment focused on community-dwelling adults aged\u2009\u2265\u200960\u00a0years reporting subjective cognitive concerns. Centers were randomized to: (A) the Subjective Cognitive Decline Questionnaire\u00a0(SCD-Q) only, (B) SCD-Q plus digital cognitive testing, or (C) SCD-Q plus digital testing plus blood biomarkers (A\u03b21-42/1-40, pTau181, GFAP, NfL). The primary endpoints were feasibility and acceptability, assessed through structured questionnaires and follow-up interviews with participants and general practitioners. Secondary endpoints examined latent cognitive structures and biomarker associations. Exploratory factor and clustering analyses revealed multimodal subgroups across subjective, digital, and biological measures, which informed a hypothesis-generating three-tier adaptive detection framework (low, medium, high intensity). Among the 473 participants (mean age 74.1\u2009\u00b1\u20097.6\u00a0years; 66% female; 63% with tertiary education), both feasibility and acceptability were high: Participants described the assessments as personally relevant, clearly communicated, and medically meaningful, and appreciated the added value of digital testing and biomarkers. Digital cognitive testing and biomarkers captured distinct latent dimensions of learning/working memory, psychomotor attention, and glial and amyloid pathology. Exploratory multimodal clustering identified three dementia risk profiles-low concern, intermediate, and at risk-which informed an adaptive, tiered detection model. Notably, subjective cognitive concerns assessed by the SCD-Q were strongly associated with overall subjective symptom burden, supporting the use of brief self-report questionnaires as a pragmatic and scalable first-step stratification approach in community-based dementia detection. Community-based, tiered detection pathways for cognitive decline are feasible, acceptable, and meaningful to older adults. Exploratory multimodal profiling suggests that combining subjective, digital, and biological measures may support individualized assessment strategies. However, limited GP engagement highlights the need for stronger integration with primary care to ensure downstream diagnostics and prevention pathways. The proposed framework remains hypothesis-generating and requires prospective validation.Clinical trials registeredCogScreen has been registered at clinical trials (NCT06191952, 2023-12-20).\n\nID: 42486831\nTitle: [Natural bear bile powder attenuates lipopolysaccharide-induced acute lung injury in mice by regulating the NF-\u03baB and Nrf-2/HO-1 signaling pathways].\nAbstract: To investigate the mechanism that mediates the protective effect of bear bile powder (BBP) against lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. Cultured RAW264.7 cells were pretreated with, different concentrations of BBP, or dexamethasone (Dex) for 1 h before LPS challenge. Sixty male C57BL/6 mice were randomized into 5 groups (n=12), including a control group, a LPS-induced ALI model group, a Dex treatment group, and two BBP treatment groups treated with low- (30 mg/kg) or high-dose (120 mg/kg) BBP. The levels of inflammatory factors and oxidative stress-related indicators in the cells and mouse lung tissues were determined, and mouse lung histopathology, wet/dry weight ratio, and BALF cell count were examined; the expressions of NF-\u03baB and Nrf-2/HO-1 pathways were detected using qPCR, Western blotting, and immunohistochemistry. In LPS-stimulated RAW264.7 cells, BBP (12.5 \u03bcg/mL) significantly reduced the levels of TNF-\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, NO and ROS, enhanced SOD activity, increased mRNA expressions of I\u03baB-\u03b1, Nrf-2, and HO-1, and lowered mRNA expressions of TNF-\u03b1, IL-1\u03b2, Keap-1, and NF-\u03baB (p65). The ALI mouse models showed severe lung pathologies and edema, increased BALF cell counts, and increased levels of TNF\u2011\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, and NO, lowered SOD activity with reduced protein expressions of I\u03baB-\u03b1, Nrf-2, and HO-1 and increased expressions of Keap-1 and p65. Treatment with high-dose BBP significantly ameliorated lung pathologies in the mouse models and improved the aberrant alterations in pulmonary expressions of inflammatory factors, oxidative stress-related indicators and the NF-\u03baB and Nrf-2/HO-1 pathways. BBP protects against LPS-induced ALI in mice possibly by targeting the Nrf-2/HO-1 and NF-\u03baB pathways, suggesting its potential as a therapeutic agent for ALI. \u76ee\u7684: \u63a2\u7a76\u718a\u80c6\u7c89\uff08BBP\uff09\u901a\u8fc7\u8c03\u63a7NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u5bf9\u8102\u591a\u7cd6\u8bf1\u5bfc\u7684\u6025\u6027\u80ba\u635f\u4f24\uff08ALI\uff09\u5c0f\u9f20\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u4f53\u5916\u5b9e\u9a8c:\u91c7\u7528\u8102\u591a\u7cd6\uff08LPS\uff09\u8bf1\u5bfcRAW264.7\u7ec6\u80de\u5efa\u7acb\u4f53\u5916\u6a21\u578b\uff0c\u8bbe\u7f6e\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001\u5730\u585e\u7c73\u677e\uff08Dex\uff0c25 \u03bcg/mL\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff086.25 \u03bcg/mL\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff0812.5 \u03bcg/mL\uff09\u3002\u4f53\u5185\u5b9e\u9a8c:\u5c0660\u53eaC57BL/6\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001Dex\u7ec4\uff085 mg/kg\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff0830 mg/kg\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff08120 mg/kg\uff09\uff0c12\u53ea/\u7ec4\u3002\u901a\u8fc7ELISA\u548c\u76f8\u5173\u8bd5\u5242\u76d2\u68c0\u6d4b\u7ec6\u80de\u548c\u80ba\u7ec4\u7ec7\u4e2d\u708e\u75c7\u4e0e\u6c27\u5316\u5e94\u6fc0\u6307\u6807;\u901a\u8fc7\u80ba\u7ec4\u7ec7\u75c5\u7406\u5206\u6790\u3001\u514d\u75ab\u7ec6\u80de\u8ba1\u6570\u548c\u80ba\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u7b49\u6307\u6807\u8bc4\u4ef7BBP\u5bf9ALI\u7684\u5e72\u9884\u4f5c\u7528\u3002\u901a\u8fc7qRT-PCR\u3001Western blotting\u548c\u514d\u75ab\u7ec4\u5316\u6cd5\u5206\u6790NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u76f8\u5173\u86cb\u767d\u4e0e\u57fa\u56e0\u7684\u8868\u8fbe\u53d8\u5316\u3002\u7ed3\u679c: \u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\u7ec4\uff0812.5\u03bcg/mL\uff09\u663e\u8457\u964d\u4f4eTNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u4e00\u6c27\u5316\u6c2e\uff08NO\uff09\u548c\u6d3b\u6027\u6c27\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff0c\u4e14I\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff0c\u800cTNF-\u03b1\u3001IL-1\u03b2\u3001Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff08P<0.05\uff0cP<0.01\uff0cP<0.001\uff09\u3002\u52a8\u7269\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u7ed3\u6784\u7d0a\u4e71\uff0c\u80ba\u6ce1\u58c1\u589e\u539a\uff0c\u80ba\u6ce1\u5185\u53ef\u89c1\u5927\u91cf\u708e\u75c7\u7ec6\u80de\u6d78\u6da6\uff0c\u80ba\u7ec4\u7ec7\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u53ca\u652f\u6c14\u7ba1\u80ba\u6ce1\u704c\u6d17\u6db2\uff08BALF\uff09\u603b\u7ec6\u80de\u6570\u5347\u9ad8\uff08P<0.01\uff09;\u80ba\u7ec4\u7ec7\u4e2d\u7684TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u542b\u91cf\u5347\u9ad8\uff0c\u800cSOD\u6d53\u5ea6\u964d\u4f4e\uff08P<0.01\uff0cP<0.001\uff09;\u4e14\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff0cKeap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\uff08120 mg/kg\uff09\u7ec4\u80fd\u6539\u5584\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u75c5\u7406\u635f\u4f24\u72b6\u6001\uff0c\u6539\u5584\u80ba\u80bf\u80c0\u7a0b\u5ea6\uff0c\u964d\u4f4eBALF\u603b\u7ec6\u80de\u6570\u3001TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09;\u540c\u65f6\uff0cBBP\u4e0a\u8c03\u4e86\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u5e76\u6291\u5236\u4e86Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09\u3002\u7ed3\u8bba: BBP\u53ef\u80fd\u901a\u8fc7\u4f5c\u7528\u4e8eNrf-2/HO-1\u548cNF-\u03baB\u4fe1\u53f7\u901a\u8def\u5bf9LPS\u8bf1\u5bfc\u7684ALI\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u540e\u7eed\u7814\u7a76\u6f5c\u5728\u7684\u6cbb\u7597ALI\u836f\u7269\u63d0\u4f9b\u4f9d\u636e\u3002.\n\nID: 42486687\nTitle: A multimodal machine learning model integrating plasma biomarkers and MRI metrics for non-invasive prediction of amyloid-\u03b2 pathology in mild cognitive impairment.\nAbstract: BackgroundAccurate, non-invasive prediction of cerebral amyloid-\u03b2 (A\u03b2) pathology in mild cognitive impairment (MCI) remains challenging yet critical for early intervention.ObjectiveTo develop a multimodal machine learning model integrating clinical features, plasma biomarkers, and structural MRI metrics for non-invasive A\u03b2 prediction.MethodsData were obtained from the Alzheimer's Disease Neuroimaging Initiative. Participants with concurrent plasma biomarkers, 3D T1-weighted MRI, and amyloid assessments were included. Logistic Regression, Decision Tree, and Support Vector Machine models were constructed using clinical, plasma, MRI, and combined features. Performance was evaluated via internal validation and external testing in a cognitively unimpaired cohort using AUC, calibration curves, and decision curve analysis. The prognostic value of the model-derived A\u03b2 risk probability was assessed using Cox regression in an independent longitudinal MCI cohort.ResultsThe optimal Logistic Regression model incorporated APOE \u03b54 status, Mini-Mental State Examination score, plasma p-Tau217, A\u03b242/A\u03b240 ratio, and bilateral hippocampal and left amygdalar volumes. The combined model achieved an AUC of 0.875 in internal validation and maintained robust performance in the external unimpaired cohort (AUC\u2009=\u20090.883), outperforming single-modality models. The predicted A\u03b2-positive risk probability effectively stratified disease progression risk in MCI patients (C-index\u2009=\u20090.771).ConclusionsA multimodal model integrating plasma and MRI features accurately predicts A\u03b2 pathology and progression risk, offering a practical non-invasive tool for early Alzheimer's disease screening and risk stratification.\n\nID: 42486456\nTitle: Investigation of Anti-Asthmatic Constituents and Mechanisms of Cimicifugae Rhizoma Based on LC-MS Analysis, Network Pharmacology and Experimental Validation.\nAbstract: Cimicifugae Rhizoma was used for the treatment of asthma in traditional Chinese medicine. The triterpenoid partition of Cimicifugae Rhizoma, named as 'Ximingting', is commercially used for perimenopausal syndrome. However, the anti-asthma constituents and mechanism of Cimicifugae Rhizoma, and the therapeutic effect of 'Ximingting' on asthma remain unknown. This study aims to illustrate anti-asthma constituents of Cimicifugae Rhizoma and 'Ximingting', and explored the underlying molecular mechanisms. The ethyl acetate fraction of Cimicifugae Rhizoma extract (EAEC) was prepared accroding to the manufacturing process of 'Ximingting'. The chemical composition of EAEC were analyzed by UPLC-MS/MS. An ovalbumin (OVA)-induced asthma mouse model was used for evaluateing the bioassay in vivo. Network pharmacology was adopted for predicting anti-asthmatic targets/pathways, validated by molecular docking, ELISA, Western blot, qRT-PCR, immunofluorescence, and flow cytometry. Fifty-eight constituents (mainly triterpenoids) were identified in EAEC. EAEC significantly attenuated OVA-induced airway inflammatory infiltration, reduced inflammatory cytokines, and restored Th1/Th2 balance in mice. Network pharmacology indicated that anti-asthmatic effect of EAEC was related to inflammation, oxidative stress, and T-cell differentiation. Further experiments demonstrated that EAEC activated Keap1-Nrf2 signaling to enhance antioxidant capacity, and inhibited STAT6 phosphorylation and GATA3 expression, thereby blocking CD4 T cell differentiation into Th2 cells. Triterpenoids in Cimicifugae Rhizoma exert anti-asthmatic effects by activating Keap1-Nrf2 pathway against oxidative stress and regulating STAT6/GATA3 pathway to balance immunity. These findings reveal the anti-asthmatic mechanism of Cimicifugae Rhizoma and suggest the potential of 'Ximingting' for further anti-asthmatic investigation.\n\nID: 42486330\nTitle: Metformin enhances hippocampal excitatory synaptic transmission and preserves synaptic plasticity under amyloid-\u03b2 oligomer-induced dysfunction.\nAbstract: Early stages of Alzheimer's disease (AD) are characterized by synaptic dysfunction and alterations in synaptic plasticity that precede neuronal loss. Soluble amyloid-\u03b2 oligomers (A\u03b2Os) are important contributors to these early synaptic alterations by disrupting excitatory neurotransmission and impairing hippocampal function. Metformin (Met), a widely used antidiabetic drug, has recently gained attention for its potential neuroprotective properties; however, its effects on hippocampal synaptic transmission and plasticity under amyloid-induced stress remain incompletely understood. In the present study, we investigated the effects of orally administered Met (200 mg/kg/day) on basal excitatory synaptic transmission, presynaptic release probability, and long-term synaptic plasticity in hippocampal slices from rats subjected to stereotaxic injection of A\u03b2Os into the CA1 region. Using field electrophysiological recordings, we show that Met significantly enhances basal excitatory synaptic transmission, increases presynaptic release probability, potentiates long-term potentiation (LTP), and attenuates long-term depression (LTD). Notably, Met prevented the impairments in synaptic transmission and plasticity induced by A\u03b2Os, maintaining synaptic responses at levels comparable to those observed in control animals. Together, these findings indicate that Met modulates hippocampal synaptic function and preserves physiological forms of synaptic plasticity under amyloid-induced stress conditions. Our results identify synaptic transmission and plasticity as functionally relevant targets of Met action and support further investigation of Met as a potential strategy for preserving synaptic function during the early stages of AD.\n\nID: 42486328\nTitle: Redox regulation of 6-phosphogluconate dehydrogenase (6PGDH) isozymes and gene regulation by nitric oxide (NO) and melatonin during pepper fruit ripening.\nAbstract: 6-Phosphogluconate dehydrogenase (6PGDH) functions in the oxidative phase of the pentose phosphate pathway (oxiPPP), together with glucose-6-phosphate dehydrogenase (G6PDH). These two enzymes play central roles in cellular NADPH generation. In pepper fruit, two genes were identified in the transcriptome, designated Ca6PGDH1 and Ca6PGDH2, which appear to encode a peroxisomal and a plastidial putative isozyme, respectively. During ripening, Ca6PGDH1 exhibited only minor changes in its expression, whereas Ca6PGDH2 was markedly downregulated. The expression patterns of both genes diverged in response to exposure to a nitric oxide (NO)-enriched atmosphere and melatonin, while both NO and melatonin treatments partially mitigated the downregulation of Ca6PGDH2 but not that of Ca6PGDH1. At the enzymatic level, the total 6PGDH activity exhibited a modest decline during ripening. Isoenzymatic analysis using non-denaturing polyacrylamide gel electrophoresis revealed three distinct isozymes, designated 6PGDH I to III, in order of increasing electrophoretic mobility. In vitro assays examining the effects of various reducing agents, including glutathione (GSH) and L-cysteine (L-Cys), as well as signaling molecules such as NO, peroxynitrite (ONOO-), hydrogen sulfide (H2S), and cyanide, showed that the NO donors and H2S exerted inhibitory effects on some isozymes, with the strongest inhibition observed for Ca6PGDH III whereas reducing compounds (GSH and Cys) protected against these inhibitory effects. Together, these results highlight Ca6PGDH as a redox-sensitive enzyme that may contribute to metabolic and signaling homeostasis during pepper fruit ripening.\n\nID: 42486010\nTitle: Merocyanine derivatives as theranostic agents for cognitive improvement and real-time imaging of amyloid-\u03b2 in APP/PS1 transgenic mice.\nAbstract: Amyloid-\u03b2 (A\u03b2) is widely recognized as a biomarker for the diagnosis and treatment of Alzheimer's Disease (AD). In our previous work, a series of merocyanine fluorescent probes were designed, synthesized and evaluated for the imaging of A\u03b2 plaques. Here, we further identified the representative probe D4, which not only demonstrates the characteristics of a highly sensitive fluorescent probe for real-time imaging of A\u03b2 content in the brain of APP/PS1 mice, but also exhibited the ability to treat AD, including inhibition of A\u03b2 aggregation (inhibition rate: 89.5%), antioxidant activity (3.4 times that of Trolox); AChE inhibitory activity (IC50\u00a0=\u00a00.5\u00a0\u00b1\u00a00.0\u00a0\u03bcM) and the capacity to cross the BBB (Pe\u00a0=\u00a08.6\u00a0\u00b1\u00a00.7). Additionally, D4 dramatically attenuates A\u03b2-induced SH-SY5Y cell death by preventing the generation of ROS, and intravenous administration of 0.5\u00a0mg/kg D4 for 15\u00a0days significantly improved the cognitive ability of 7-month-old APP/PS1 mice by protecting hippocampal and cortex neurons from necrosis, attenuating oxidative stress in the hippocampus and cortex, and reducing A\u03b2 burden deposition. These findings strongly suggest that D4 owns a high theranostic potential for treating AD.\n\nID: 42485915\nTitle: Stearoyl CoA desaturase 1 deficiency increases ferroptosis susceptibility in chicken embryonic liver cells.\nAbstract: Ferroptosis is an iron-dependent form of programmed cell death driven by lipid peroxidation. It is increasingly recognized as a contributor to liver cell injury. Stearoyl-CoA desaturase 1 (SCD1) is a rate-limiting enzyme in monounsaturated fatty acid synthesis. It plays a key role in maintaining lipid homeostasis and may affect cellular susceptibility to ferroptosis. However, it remains unclear whether SCD1 restrains ferroptosis-associated injury in chicken embryonic liver (CEL) cells. Therefore, this study aimed to investigate the role of SCD1 in regulating ferroptosis susceptibility and cellular injury related to ferroptosis in CEL cells, with a focus on its effects on lipid metabolism, oxidative stress, and iron homeostasis. The results showed that SCD1 knockdown reduced intracellular lipid droplet area, triglyceride, and total cholesterol levels in CEL cells (P < 0.05). In addition, SCD1 knockdown induced mitochondrial ultrastructural changes associated with ferroptosis, including mitochondrial shrinkage, increased membrane density, and cristae disruption. It also aggravated oxidative stress, as shown by increased reactive oxygen species, oxidized glutathione, and malondialdehyde levels and decreased glutathione content (P < 0.05). SCD1 knockdown reduced cell viability, whereas oleic acid or ferrostatin-1 treatment partially reversed this decrease (P < 0.05). Moreover, SCD1 knockdown increased ACSL4 expression and decreased SLC7A11, GPX4, and Nrf2 expression at both the mRNA and protein levels (P < 0.05). SCD1 knockdown further reduced mitochondrial membrane potential and increased lipid peroxidation, intracellular Fe\u00b2\u207a levels, and total iron content (P < 0.05). In contrast, SCD1 overexpression increased lipid accumulation, reduced reactive oxygen species levels, increased glutathione content, increased SLC7A11, GPX4, and Nrf2 expression, and decreased ACSL4 protein expression (P < 0.05) without significantly affecting ACSL4 mRNA expression. These findings suggest that SCD1 regulates the susceptibility of CEL cells to ferroptosis and exerts a protective effect by improving lipid metabolism, antioxidant defenses, and mitochondrial function, indicating that SCD1 is a key regulatory factor in maintaining the homeostasis and health of chicken liver.\n\nID: 42485748\nTitle: Cognitive dysfunction in Parkinson's disease: Hippocampal vulnerability and redox-driven mechanisms.\nAbstract: Cognitive dysfunction is one of the most disabling non-motor manifestations of Parkinson's disease (PD), progressing from mild cognitive impairment to Parkinson's disease dementia. Although multiple pathological processes have been individually implicated, the mechanisms linking neurotransmitter deficits, proteinopathies, circuit vulnerability, and neurodegeneration remain insufficiently integrated. Here, we synthesize current evidence on the pathophysiology of cognitive impairment in PD, emphasizing the convergence of dopaminergic, cholinergic, noradrenergic and serotonergic dysfunction with \u03b1-synuclein, tau and amyloid-\u03b2 pathology. We highlight the hippocampus - particularly the CA2 subregion - as a critical anatomical hub connecting synaptic dysfunction, memory impairment, and dementia progression. Accumulating evidence identifies oxidative stress and neuroinflammation as central drivers across these pathological domains. Among endogenous sources of reactive oxygen species, NADPH oxidases (NOX), especially Nox4, emerge as key regulators of redox imbalance, protein aggregation and glial-neuronal interactions. Increased Nox4 activity correlates with hippocampal damage and cognitive decline, whereas experimental inhibition of Nox4 preserves synaptic integrity and improves memory performance in preclinical models. By integrating molecular, cellular and systems-level findings, this review positions redox dysregulation - and NOX-dependent signaling in particular - as a unifying mechanism underlying cognitive decline in PD, and discusses emerging therapeutic strategies targeting redox pathways, highlighting NOX modulation as a promising approach to modify the course of Parkinson's disease-associated cognitive impairment.\n\nID: 42484938\nTitle: The Clearance-Centered Bottleneck in Alzheimer's Disease: From Coupled Glymphatic-Lymphatic Circuits to Therapeutic Opportunities.\nAbstract: While anti-amyloid-beta (A\u03b2) monoclonal antibodies have achieved substantial success in reducing plaque burden, their modest clinical impact highlights an \"efficacy ceiling\" that necessitates a re-evaluation of Alzheimer's disease (AD) pathogenesis. This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap. To overcome the current therapeutic plateau, we advocate for multinode interventions that combine amyloid-targeting therapies with clearance-enhancing agents, supported by a readiness-tiered imaging strategy-standardized proxies such as DTI-ALPS and PVS burden as enrichment/secondary endpoints and dynamic contrast-enhanced MRI for mechanistic proof-of-concept.\n\nID: 42484690\nTitle: Serial failure of the brain clearance continuum in Alzheimer's disease: mechanisms and therapeutic perspectives.\nAbstract: Alzheimer's disease (AD) is usually regarded as a neurodegenerative disorder defined by amyloid-\u03b2 (A\u03b2) deposition and abnormal tau accumulation. Increasing evidence suggests that reduced clearance of metabolic waste and pathological proteins from the brain also contributes to disease onset and progression. Previous studies have often considered choroid plexus (CP) function, glymphatic exchange, and meningeal lymphatic drainage as separate clearance processes. A continuous framework linking these structures and functions is still lacking. This review integrates recent clinical and experimental evidence and proposes the brain clearance continuum as an interpretative framework. It describes three interlinked functional interfaces: the upstream choroid plexus-cerebrospinal fluid (CP-CSF) inflow interface, the midstream parenchymal perivascular exchange interface, and the downstream meningeal lymphatic outflow interface. Under physiological conditions, these interfaces support CSF movement, parenchymal solute exchange, and the outward removal of metabolic waste. In AD, disrupted CSF homeostasis, impaired perivascular exchange, and obstructed meningeal lymphatic outflow may interact, leading to serial failure of the brain clearance continuum. This process is closely associated with A\u03b2/tau accumulation, vascular dysfunction, neuroinflammation, and cognitive decline. We also summarise potential therapeutic strategies directed at different clearance interfaces, whilst emphasising that most evidence remains preclinical or exploratory. The brain clearance continuum provides a systematic framework for understanding clearance failure in AD. It may also offer a theoretical basis for future mechanistic studies and therapeutic development that are stratified by clearance interface and disease stage.\n\nID: 42484558\nTitle: E326K GBA polymorphism is associated with clinical and pathological features of synucleinopathy in the absence of overt Parkinson's disease or Lewy body dementia.\nAbstract: Heterozygote carriers of Gaucher's disease mutations and other polymorphisms in the glucocerebrosidase (GBA) gene show an increased incidence of Parkinson's disease. We hypothesized that common GBA polymorphisms would be associated with subtle parkinsonian features, mild cognitive impairment, and \"silent\" Lewy body (LB) pathology in aging individuals without a clinical diagnosis of parkinsonism. The most prevalent GBA variants, T369M and E326K, appear in the general population at rates of approximately 0.6% and 1%, respectively. We evaluated 845 participants from the Oregon Alzheimer's Disease Research Center (OADRC) with SNP data generated by the National Centralized Repository of Alzheimer's Disease (NCRAD). Twenty-one subjects were E326K carriers and eighteen were T369M carriers. Clinical measures and postmortem neuropathology were compared between each SNP group and non-carriers. Although there were no statistically significant clinical differences related to synucleinopathy across groups, neuropathological analyses revealed a significantly higher prevalence of LB pathology in E326K carriers compared to T369M carriers. When stratifying each genetic group by LB status (LB+ or LB-), LB+ E326K carriers demonstrated a significant reduction in Mini-Mental State Examination (MMSE) scores compared with LB- non-carriers and a modest decrease compared with T369M carriers. These preliminary findings from a small, uni-center cohort suggest that the E326K GBA polymorphism may predict LB pathology and subtle cognitive decline in aging individuals who lack overt parkinsonian symptoms. Further validation in a larger cohort is warranted. Identifying at-risk individuals through targeted genetic screening may ultimately support earlier intervention and preventative care strategies. Understanding How Two Common GBA Gene Variants Affect Brain Aging in People Without Parkinson's Disease: What We Learned by Comparing Thinking Abilities and Brain Changes in Older AdultsThis study explored whether two common changes in the GBA gene, called E326K and T369M, influence how the brain ages in people who never developed Parkinson's disease during life. We wanted to learn whether these genetic differences affect thinking or memory and whether they are linked to changes in the brain that are usually seen only after symptoms appear. This question matters because many people now learn about their genetic risks through medical or consumer testing, yet doctors often do not have clear information about what these results mean for older adults who have no symptoms. To study this, we followed a large group of older adults who completed yearly thinking and movement tests and then donated their brains for research. This approach allowed us to compare their everyday functioning with the actual brain changes seen under the microscope. We found that people with the E326K variant showed more of the protein buildup typically linked to Parkinson's disease, even though they never showed the disease in life. They also tended to have lower memory scores. This suggests that E326K may contribute to \u201csilent\u201d brain changes long before symptoms appear. In contrast, people with the T369M variant did not show these harmful changes. They had no signs of Parkinson's-related protein buildup and tended to have fewer Alzheimer's-related changes as well, along with slightly better memory performance. These findings show that not all GBA variants act the same way. One variant may increase risk for early, hidden brain changes, while another may be neutral or even somewhat protective. Understanding these differences can help doctors better explain genetic test results, guide decisions about monitoring and follow-up, and support future research aimed at early prevention of brain diseases.\n\nID: 42483925\nTitle: Ganoderma sinense Polysaccharides Improve Cognition in a Mouse Model of Alzheimer's Disease by Modulating Gut Microbiota and Short-Chain Fatty Acid Metabolism.\nAbstract: The number of patients with Alzheimer's Disease (AD) worldwide is expected to reach 152 million by 2050, but developing an effective AD treatment remains challenging. This study purified two polysaccharides (GSP1 and GSP2) from Ganoderma sinense, a traditional Chinese medicine, and investigated their potential therapeutic effects against AD. GSP1 and GSP2 were purified and characterized for key physicochemical properties, including monosaccharide composition and molecular weight. In vitro neuroprotective efficacy was evaluated using glutamate-challenged SH-SY5Y cells. For in vivo assessment, an AlCl\u2083/D-galactose induced AD mouse model was established to quantify cognitive/memory enhancement. Multiomic analysis of the gut microbiota, Short-Chain Fatty Acid (SCFAs) metabolomics, and behavioural tests were conducted to elucidate the therapeutic mechanisms of GSP1. Both GSP1 and GSP2 conferred neuroprotection against toxin-induced damage. Notably, GSP1 demonstrated superior efficacy compared with GSP2, significantly enhancing cognitive/ memory performance and reducing amyloid-\u03b2 plaque deposition. Furthermore, GSP1 changed gut microbial diversity and SCFA metabolic profiles. Critical genus-level correlations emerged: Turicibacter, Jeotgalicoccus, and Staphylococcus were positively associated with therapeutic outcomes, whereas Odoribacter was negatively associated. Natural polysaccharides, particularly GSP1, demonstrate therapeutic potential against AD by modulating gut microbiota. Mechanistically, this effect is linked to reshaping microbial communities and affecting the production of neuroprotective SCFAs. Although these findings position GSP1 as a promising AD therapeutic candidate, deeper exploration of gut-brain axis mechanisms remains essential for clinical translation. GSP1 emerges as a promising therapeutic candidate for AD, offering a new approach to developing AD-targeted pharmaceuticals and nutraceuticals.\n\nID: 42483739\nTitle: Targeting the 4EBP1/HSP90\u03b2/Nrf2 Axis Sensitizes \u03b2-catenin-mutant Hepatocellular Carcinoma to mTOR Inhibitors via Ferroptosis Induction.\nAbstract: The aberrant activation of the mTOR pathway and its crosstalk with other signaling cascades represent key drivers of hepatocellular carcinoma (HCC) progression. mTOR-mediated ferroptosis suppression has been implicated in HCC resistance to chemotherapy. This study aimed to elucidate the mechanisms underlying mTOR inhibitor resistance and to evaluate the therapeutic potential of multidrug combinations in \u03b2-catenin-mutant HCC. MHCC97H and SNU449 cells were transfected with 4EBP1WT, 4EBP1A4, or HSP90\u03b2 expression plasmids and then treated with rapamycin to assess their effects on ferroptosis and rapamycin sensitivity. The role of 4EBP1 in regulating ferroptosis was further explored by Western blotting, co-immunoprecipitation, and immunofluorescence. The inhibitory effects of mTOR inhibitors (rapamycin, MLN0128), ERK inhibitors (PD901), and their combination (MLN0128 + PD901) on tumor cells were evaluated. HCC mouse models were generated via hydrodynamic tail vein injection of c-Met/\u03b2-catenin\u0394N90 or c-Met/\u03b2-catenin\u0394N90/4EBP1A4 plasmids to evaluate the therapeutic effects of the four treatment regimens. Rapamycin more potently inhibited mTOR/RPS6 than mTOR/4EBP1 and concurrently induced ferroptosis. 4EBP1A4 promoted ferroptosis and potentiated rapamycin efficacy. Mechanistically, 4EBP1A4 competitively bound HSP90\u03b2, displacing Keap1, thereby increasing Keap1-Nrf2 complex formation and promoting Nrf2 degradation. Furthermore, rapamycin, MLN0128, PD901, and their combination reduced p-4EBP1 levels, induced ferroptosis, and inhibited HCC cell proliferation, thereby suppressing tumor growth, with the combination exhibiting the strongest effect. 4EBP1A4 enhances Nrf2 ubiquitination and degradation via the HSP90\u03b2/Keap1 axis, relieving mTOR-mediated ferroptosis suppression and synergistically improving rapamycin efficacy. Additionally, rapamycin, MLN0128, and PD901 suppress HCC progression by inducing ferroptosis, with their combination showing superior potency.\n\nID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.\n\nID: 42346121\nTitle: Dexmedetomidine Preserves Hippocampal Neurogenesis During Recovery from Neonatal Hyperoxia in Rats.\nAbstract: Neonatal hyperoxia induces oxidative stress that disrupts neurodevelopmental processes. While dexmedetomidine (DEX) exhibits acute neuroprotective properties, its long-term impact on developmental trajectories during recovery remains incompletely understood. This study examined whether a single neonatal dose of DEX modulates hippocampal neurogenesis following hyperoxia across defined postnatal stages. Six-day-old Wistar rats were exposed to 80% oxygen for 24 h and evaluated at postnatal days (P) 9, 11, and 14 after recovery in room air. Mechanistically, hyperoxia permanently triggered apoptotic cascades, evidenced by sustained transcript upregulation and increased histological apoptosis and cell loss across the cortex and hippocampus, while disrupting the hippocampal progenitor niche, suppressing key differentiation factors (Sox2, Tbr2, Prox1, Calb1) and altering mature NeuN expression. Likewise, markers for autophagy (Atg5/12, Beclin1), neurotrophins (BDNF, NGF, NT3), and plasticity markers (Nrp1, Sem3a) showed reduced expression. Proactive treatment with DEX (5 \u00b5g/kg) significantly reversed these detrimental patterns. First, DEX elicited a robust antioxidant response (Nrf2, SOD1, SOD3 induction). Second, DEX effectively suppressed hyperoxia-induced programmed cell death and tissue degeneration up to P14. Crucially, this dual protection sustained the neurogenic niche, safeguarding autophagy processes as well as neurotrophic and neuronal plasticity mediators, while showing excellent safety under normoxia. In conclusion, a single dose of DEX mitigates acute oxygen injury and exhibits beneficial, stage-specific effects within hippocampal neurogenic niches during the postnatal phase, highlighting its potential to preserve neurodevelopmental trajectories.\n\nID: 42335888\nTitle: An emergent disease-associated motor neuron state precedes cell death in ALS.\nAbstract: To define molecular determinants of motor neuron degeneration in amyotrophic lateral sclerosis (ALS), we generated longitudinal single-nucleus transcriptomes and chromatin accessibility profiles of spinal motor neurons together with spatial transcriptomics from the SOD1-G93A mouse model. Vulnerable alpha motor neurons showed thousands of molecular changes, marking a transition into a distinct cell state we named \"disease-associated motor neurons\" (DMs). We identified transcription factor networks that govern how healthy cells transition into DMs and those associated with motor neuron subtype-selective vulnerability. Upregulation of DM-associated transcription factors in human motor neurons induced key features of DMs, demonstrating an active regulatory component. Human ALS spinal cord single-nucleus RNA sequencing data demonstrated conservation of the DM signature in alpha motor neurons, and human orthologs of regions differentially accessible in SOD1-G93A mouse motor neurons were enriched for ALS genetic risk variants. Together, these findings establish a conserved, genetically linked motor neuron signature in ALS.\n\nID: 42334525\nTitle: Synthesis and multilevel evaluation of benzimidazole-based anticancer compounds: DNA/serum albumin interaction, and in-depth theoretical insights.\nAbstract: Within the scope of this investigation, two novel compounds (3a and 3b) were designed and synthesized in two steps. Compounds 3a and 3b were tested utilizing the MTT study to evaluate their in vitro cytotoxic activity against healthy human embryonic kidney, lung cancer, breast cancer, and human liver cancer cell lines. It was determined that compound 3b exhibited high levels of cytotoxic activity against both liver and breast cancer cell lines, with IC50 values of 10.83 and 11.55 \u00b5M, respectively. Also, to elucidate the anticancer mechanism of compounds, pro-apoptotic BAX and BiD, anti-apoptotic BCL2 and BCL-xl, oxidant enzymes PRDX1 and SOD1 levels were examined by RT-qPCR. Moreover, cellular oxidative stress levels were spectrophotometrically measured, and cellular senescence was evaluated via the senescence-associated \u03b2-galactosidase test. DFT calculations and RDG, ELF, and LOL analyses were performed to demonstrate the reactivity of these compounds. Compounds significantly down-regulated anti-apoptotic genes, whereas mRNA levels of pro-apoptotic genes were up-regulated in MCF-7 cells. Moreover, oxidative stress status was significantly increased depending on the compound treatment. Consistently, PRDX1 and SOD1 levels were also significantly up-regulated. Furthermore, cellular senescence was significantly induced by the compounds. Fluorescence spectroscopy demonstrated strong binding of both compounds with CT-DNA, characterized by static quenching mechanism and binding constants of 6.02\u2009\u00d7\u2009106M-\u20091(for 3a) and 8.69\u2009\u00d7\u2009106M-\u20091(for 3b), suggesting an intercalative binding mode. In contrast, moderate affinity toward BSA indicated suitable transport characteristics with reduced nonspecific protein binding. Molecular docking studies supported the experimental findings. These combined results verify the potential of the synthesized derivatives as promising candidates for further investigation as biologically active anticancer agents.\n\nID: 42320547\nTitle: Proteomic analysis reveals early pathological defects in corticospinal motor neurons of a spastin model of hereditary spastic paraplegia, which are improved by NU-9 treatment.\nAbstract: Upper motor neuron (UMN) degeneration is a characteristic feature of hereditary spastic paraplegia (HSP), a genetically heterogeneous heritable neurodegenerative disorder resulting from mutations in over ninety genes. The mutations in the SPAST gene, which encodes the microtubule-severing protein spastin, are responsible for about 40% of all HSP cases. To date, the cellular and molecular mechanisms linking mutant spastin protein to UMN vulnerability in HSP patients remain unknown and there are no disease modifying therapies. To address this knowledge gap, we isolated pure populations of corticospinal motor neurons (CSMN; a.k.a. UMN in mice) from SPASTC448Y-UeGFP reporter mice at two pre-symptomatic time points and performed bottom-up proteomic analyses to reveal changes in their proteome that informs the underlying causes of their initial vulnerability. We find dynamic changes in their proteome and that limitations with cytoarchitectural integrity and stability of key organelles contribute to their neuronal vulnerability. Since the compound NU-9 was shown to improve similar cellular problems in CSMN that are diseased due to misfolded SOD1 toxicity and TDP-43 pathology, we further investigated its effect on the well-established pathological features of HSP that are recapitulated in the SPASTC448Y mice. We find that NU-9 treatment (100\u00a0mg/kg, for 100\u00a0days) significantly prevented degeneration of corticospinal axons, restored the integrity of mitochondria and endoplasmic reticulum, and reduced the presence of electron-dense accumulations in the CSMN of SPASTC448Y mice.\n\nID: 42302989\nTitle: Establishment and characterization of Hanwoo cumulus cell line for heat stress studies.\nAbstract: Heat stress (HS) negatively affects cattle reproduction, decreasing livestock productivity. HS response in cattle reproductive cumulus cells remain understudied due to limited cell lines and comprehensive omics data. This study aims to establish immortalized cumulus cells from Hanwoo cattle as a HS model and explores their HS response using molecular markers including transcriptomics and proteomics approaches. Immortalized cumulus cells were established from primary cumulus isolated from fresh Hanwoo cattle follicles by using piggyBac transposon-mediated SV40T expression system. HS condition was optimized using reactive oxygen species (ROS) detection, quantitative reverse-transcription polymerase chain reaction, and Western blotting on oxidative and endoplasmic reticulum stress markers under different HS and recovery periods (4 h, 12 h, and 24 h). Transcriptomic and proteomic data were generated to identify HS-related differentially expressed genes (DEG) and proteins (DEP) utilized for gene ontology (GO) and pathway enrichment analysis. We established the first immortalized cumulus cell line with high specificity (99% CD44[+]) for in vitro HS study. ROS accumulation was observed at 4 h HS, leading to immediate upregulation of HSP70 and BiP proteins, with oxidative stress gene expression (SOD1, CAT, GPX1) peaked at 12 h HS. We identified 754 DEGs (fold change\u2265|2|) and 357 DEPs (fold change\u2265|1.5|) related to HS in the cumulus cell line. Enrichment analysis exhibited upregulation in GO and pathways related to protein unfolding and cellular response to HS, respectively, from both the DEG and DEP list. Downregulated DEG and DEP showed significant enrichment in GO related to the extracellular matrix, potentially affecting cumulus-oocyte complex communication for reproductive function. The cumulus cell line serves as a robust in vitro model for studying HS response in cattle reproductive system. The multi-omics data could help clarify the comprehensive HS response and identify possible molecular targets to mitigate negative HS effects in the future.\n\nID: 42293850\nTitle: Curcumin improves bladder dysfunction in diabetic rats by attenuating oxidative stress via the Keap1/NRF2/HO-1 pathway.\nAbstract: Diabetic bladder dysfunction (DBD) is a common urological complication of diabetes. Research suggests that oxidative stress (OS) is critically implicated in its development and progression. Curcumin (Cur), a natural polyphenol derived from turmeric, exhibits potent antioxidant properties and has been extensively investigated for treating OS-related disorders. Consequently, this study aims to explore the potential of Cur to mitigate DBD. In vitro, a high glucose (HG)-stimulated bladder smooth muscle cell (BSMC) model was established and treated with Cur. Cell viability was assessed by Cell Counting Kit-8 (CCK-8) assay. Intracellular reactive oxygen species (ROS) levels and the apoptosis rate were measured by flow cytometry. Protein expression was evaluated using Western blot (WB) and immunofluorescence. In vivo, rats were fed a high-fat and high-sugar diet and then induced into a diabetic rat model using streptozotocin. Subsequently, Cur was administered to these rats by oral gavage. Bladder function was assessed through urodynamic testing and histopathological examination. Protein expression in bladder tissue was analyzed by WB. Cur demonstrated a protective effect against HG-induced injury in BSMC, enhancing cell viability and reducing ROS generation. It inhibited kelch-like ECH-associated protein 1 (Keap1) expression, thereby promoting the expression of nuclear factor erythroid 2-related factor 2 (NRF2) and its downstream effectors, heme oxygenase-1 (HO-1) and superoxide dismutase 1 (SOD1). Additionally, Cur decreased the apoptotic rate, suppressed the expression of B-cell lymphoma 2 (BCL-2)-associated X protein (BAX) and cysteine-aspartic acid protease 3 (caspase-3), and upregulated BCL-2. In diabetic rats, Cur ameliorated bladder dysfunction, as evidenced by reduced maximum micturition pressure and prolonged micturition intervals. Histological analyses revealed attenuated bladder tissue fibrosis and apoptosis, concomitant with suppressed Keap1 and elevated expression of NRF2, HO-1, and SOD1 in the bladder tissue. Cur alleviates OS and thereby ameliorates DBD in diabetic rats by regulating the Keap1/NRF2/HO-1 pathway, which highlights its therapeutic potential for DBD.\n\nID: 42286832\nTitle: Chrysin alleviates pressure overload-induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway-mediated oxidative stress response.\nAbstract: Oxidative stress plays a pivotal role in the pathogenesis of heart failure and is closely linked to myocardial remodeling, which includes myocardial hypertrophy and fibrosis. Chrysin (CHR) has multiple medicinal effects such as antioxidant, anti-inflammatory, and anti-apoptosis. This research seeks to investigate whether CHR can protect against pressure overload-induced myocardial remodeling and to explore the underlying mechanism. Transverse aortic constriction (TAC) surgery was conducted to establish a model of cardiac hypertrophy on male C57BL/6J mice. A model of cardiomyocyte hypertrophy in H9C2 cells induced by angiotensin II (Ang II) was also established. The results showed that CHR significantly improved survival and cardiac function, reduced myocardial hypertrophy and fibrosis, inhibited the expression of inflammatory mediators TNF-\u03b1 and IL-1\u03b2, suppressed cell apoptosis rate, downregulated the levels of Bcl-2 Associated X protein (BAX) and Cleaved-Caspase-3, and upregulated B-cell lymphoma/leukemia 2 (BCL-2) expression in TAC surgical mice or Ang II-treated H9C2 cells. CHR could also upregulate the levels of antioxidant enzymes SOD1 and HO-1 by mediating the nuclear translocation and expression of NRF2 to counteract oxidative stress response. The further mechanism investigation utilizing bioinformatics analysis and western blot revealed that the disease of heart failure is associated with the phosphatidylinositol\u20113\u2011kinase (PI3K)/serine/threonine-protein kinase B (AKT) signaling pathway. Collectively, our findings demonstrated that CHR might exert the improvement effects on pressure overload-induced myocardial remodeling with hypertrophy and fibrosis through regulating the PI3K/AKT/NRF2 pathway-mediated oxidative stress response to alleviate myocardial cell inflammation and apoptosis, suggesting that CHR may be a promising therapeutic agent for cardiac diseases induced by pressure overload.\n\nID: 42281377\nTitle: A Fungal-Derived Bioactive Resource for Cochlear Protection: Sanghuangporus sanghuang Extract Mitigates Acoustic Trauma through Nrf2/HO-1 Antioxidant Axis.\nAbstract: Noise-induced hearing loss (NIHL) is a major form of sensorineural hearing impairment driven by oxidative stress-mediated cochlear injury. Sanghuangporus sanghuang (SS), a medicinal fungus extensively studied in microbiology and biotechnology, is known to produce bioactive metabolites with antioxidant properties; however, its functional role in the auditory system has not been established. This study investigated the otoprotective potential of SS extract against oxidative and acoustic stress using complementary in vitro, ex vivo, and in vivo models. In H2O2-treated UB-OC1 auditory cells, SS (25-200 \u03bcg/mL) dose-dependently restored cell viability and significantly reduced intracellular reactive oxygen species accumulation. Western blot analysis demonstrated that SS suppressed the expression of apoptotic markers, including cleaved caspase-3 and cytochrome C. At the molecular level, SS upregulated Nrf2 and HO-1 expression at both mRNA and protein levels, without a significant change in Keap1 expression, indicating activation of endogenous antioxidant defense via the Nrf2/HO-1 signaling axis. Consequently, downstream antioxidant genes such as SOD1 and NQO1 were significantly upregulated. In ex vivo cochlear explant cultures, SS preserved hair cell integrity against H2O2-induced damage, as confirmed by phalloidin staining. In a murine NIHL model, oral administration of SS attenuated ABR threshold shifts, maintained Wave I amplitudes, and preserved the structural organization of outer hair cells across all cochlear turns. Collectively, these findings demonstrate that SS confers otoprotection by modulating the Nrf2/HO-1 antioxidant axis and mitigating oxidative stress-induced sensory cell injury, supporting the potential of SS as a fungal-derived functional bioactive resource for redox-associated cochlear protection.\n\nID: 42278291\nTitle: Targeting Autoimmune Myocarditis with Lemon Balm Extract: In Vivo Molecular Approach.\nAbstract: Due to the complex pathophysiology and serious outcomes of autoimmune myocarditis, we sought to determine whether ethanolic lemon balm extract (LBE) could attenuate disease progression and development of dilative cardiomyopathy (DCM). EAM was induced in Dark Agouti rats by immunization with porcine myosin. Fifty animals were allocated to five groups: healthy controls, untreated EAM, and EAM treated with LBE (50, 100, or 200 mg/kg) for six weeks. Hemodynamic parameters were monitored, and echocardiography assessed cardiac structure and function. Inflammatory, oxidative, fibrotic, and apoptotic markers were analyzed. Immunological profiling revealed that LBE significantly decreased proinflammatory cytokines (IL-1, IL-6, TNF-\u03b1, IL-4, IL-17) while restoring anti-inflammatory IL-10 levels (p < 0.05). Antioxidant activity was confirmed by reduced levels of O2-, H2O2, and TBARS, accompanied by significant increases in SOD, CAT, and GSH activity (p < 0.05), and upregulation of SOD1 and SOD2 gene expression. Additionally, LBE (200 mg/kg) markedly reversed fibrotic remodeling through suppression of TGF-\u03b2 expression and collagen deposition, as shown by Sirius Red staining, and mitigated apoptosis by modulating Bax/Bcl-2 balance and reducing TUNEL-positive cells. Collectively, these findings suggest that LBE exerts strong cardioprotective effects in EAM by regulating inflammatory, oxidative, fibrotic, and apoptotic pathways, thereby preventing myocarditis progression toward DCM.\n\nID: 42252558\nTitle: Superoxide Dismutase-Centered Modulation by Curcumin in Cardiovascular Diseases: Mechanistic Insights and Translational Implications.\nAbstract: Cardiovascular diseases (CVD) remain the leading global cause of morbidity and mortality, driven in part by dysregulated redox homeostasis and chronic inflammation. Superoxide dismutase (SOD), a key enzymatic defence against reactive oxygen species (ROS), plays a central role in maintaining cardiovascular integrity through regulation of oxidative stress across cytosolic (SOD1), mitochondrial (SOD2) and extracellular (SOD3) compartments. Impairment of SOD function contributes directly to endothelial dysfunction, myocardial injury and vascular remodelling. Curcumin (Cur), a pleiotropic polyphenol derived from Curcuma longa, has emerged as a potent modulator of SOD activity and expression. Evidence from preclinical models consistently demonstrates that Cur enhances SOD-dependent antioxidant defences, thereby attenuating oxidative damage, inflammation, apoptosis and fibrosis across multiple CVD contexts, including myocardial infarction, cardiomyopathy, hypertension and diabetic complications. While Cur also influences additional signalling pathways, such as NF-\u03baB, PI3K/AKT and Nrf2, these effects are increasingly understood to converge on SOD-mediated redox regulation. Recent advances in nanodelivery systems have further improved Cur bioavailability and its capacity to modulate SOD activity in\u00a0vivo. However, despite robust preclinical evidence, clinical validation remains limited. This review synthesizes current mechanistic and translational evidence, positioning SOD as the central mediator of Cur's cardioprotective effects and highlights key gaps in clinical translation.\n\nID: 42249210\nTitle: Dietary patterns characterized by high fiber intake in vegan and omnivorous individuals are associated with distinct salivary proteomic signatures linked to oral homeostasis.\nAbstract: We compared the salivary proteome and metaproteome of individuals with real-world dietary patterns differing in fiber intake (i.e., high- versus low-fiber intake) to examine whether their diet was associated with distinct molecular signatures in saliva. Sixteen participants from a cross-sectional study were classified into high-fiber (n\u2009=\u20098) and low-fiber (n\u2009=\u20098) intake groups based on dietary assessment. Although these groups corresponded to vegan and omnivorous patterns, respectively, classification was based on fiber intake. Groups were matched for age, sex, socioeconomic status, while major dietary differences inherent to vegan and omnivorous patterns were explicitly considered in the interpretation. Stimulated whole saliva was collected under standardized fasting conditions. Human proteomic and microbial metaproteomic analyses were performed using bottom-up DIA-PASEF. Differentially abundant proteins, enriched pathways, and metaproteomic profiles were identified using bioinformatic analyses. From 3,332 identified proteins, 1,566 were quantifiable, and 66 were differentially abundant between groups (FDR [False Discovery Rate]\u2009<\u20090.05). Multivariate analyses revealed separation according to dietary patterns differing in fiber intake: high-fiber exhibited enrichment of homeostasis, lipid metabolism, and cytoprotective pathways, with increased abundance of PRP-1/2, CA6, APOA1, and HYOU1. Low-fiber showed enrichment of immune and oxidative stress pathways, with higher SOD1, GPX1, ANXA2, ANXA8, and S100A8. Metaproteomics analysis revealed no major taxonomic differences but greater interindividual variability in the low-fiber intake group. Dietary patterns characterized by different dietary fiber intake appear associated with distinct salivary proteomic signatures. Although the contribution of other co-occurring dietary factors cannot be excluded, these findings, based on a small, highly selected cohort, suggest that fiber-rich dietary patterns may support oral homeostasis through host-driven molecular pathways rather than major shifts in microbial composition. Our findings strengthen the rationale for considering dietary patterns with high-fiber intake not only as a systemic health determinant but also as a modulator of salivary molecular functions relevant to oral disease prevention and personalized care.\n\nID: 42233578\nTitle: Effect of 17\u03b2-estradiol on brain microvascular endothelial cell oxidative stress, apoptotic susceptibility, and fibrinolytic capacity.\nAbstract: The experimental aim of this study was to determine, in vitro, the effect of estrogen on brain endothelial cell oxidative stress, apoptotic susceptibility, and tissue-type plasminogen activator (t-PA) release. Human cerebral microvascular endothelial cells (hCMECs) were cultured and treated with 17\u03b2-estradiol (100 nM), the primary and most biologically active endogenous form of estrogen in humans, for 24 h. Intracellular reactive oxygen species production was significantly lower (\u223c15%; P > 0.01) in hCMECs treated with 17\u03b2-estradiol; however, antioxidant proteins superoxide dismutase-1 (28.6\u2009\u00b1\u200911.0 vs. 36.2\u2009\u00b1\u200911.9 AU) and catalase (33.6\u2009\u00b1\u200914.0 vs. 32.1\u2009\u00b1\u200914.7 AU) were not significantly altered by 17\u03b2-estradiol. Although, there were no significant differences in the basal intracellular expression of either total caspase-3 (159.8\u2009\u00b1\u200984.9 vs. 143.6\u2009\u00b1\u200939.2 AU) or active caspase-3 (13.5\u2009\u00b1\u20094.5 vs. 15.4\u2009\u00b1\u20096.7 AU) between untreated and 17\u03b2-estradiol-treated hCMECs; the increase in active caspase-3 in response to the apoptosis stimulus staurosporine was significantly lower (\u223c30%; P = 0.02) in 17\u03b2-estradiol-treated (from 15.5\u2009\u00b1\u20096.7 to 184.5\u2009\u00b1\u200943.8 AU) compared with untreated (from 13.5\u2009\u00b1\u20094.5 to 257.6\u2009\u00b1\u200934.4 pg/mL) hCMECs. t-PA release in response to thrombin was significantly higher (P = 0.02) in 17\u03b2-estradiol-treated (from 41.6\u2009\u00b1\u200910.8 to 61.1\u2009\u00b1\u20099.2 pg/mL; \u223c45% increase) compared with untreated (43.4\u2009\u00b1\u20099.2 to 48.0\u2009\u00b1\u200911.5 pg/mL; \u223c10% increase) hCMECs. In summary, 17\u03b2-estradiol decreases oxidative stress, enhances apoptotic resistance, and increases fibrinolytic capacity in human brain microvascular endothelial cells in vitro. Reduced risk of cerebrovascular disease and thrombotic events attributed to estrogen may be mediated, in part, by these beneficial endothelial effects.NEW & NOTEWORTHY The cerebrovascular protective effects of estrogen are diverse, complex, and not fully understood. This study provides novel data demonstrating that 17\u03b2-estradiol decreases oxidative stress, enhances apoptotic resistance, and increases fibrinolytic capacity in human brain microvascular endothelial cells in vitro. These changes in endothelial cell phenotype have been linked (clinically and epidemiologically) to less cerebrovascular dysfunction and reduced ischemic stroke risk.\n\nID: 42207197\nTitle: Caffeic acid restores neurogenesis and synaptic integrity under glucolipotoxic stress by suppressing inflammation and pyroptosis.\nAbstract: Diabetes mellitus is frequently associated with cognitive dysfunction, primarily attributed to impaired hippocampal neurogenesis, oxidative stress, inflammation, and pyroptosis. Caffeic acid (CA), a dietary polyphenol, has demonstrated antioxidant and neuroprotective effects. This study evaluated the protective role of CA under diabetic-like conditions using an in vitro glucolipotoxicity model in HT-22 hippocampal neurons exposed to high glucose and oleic acid (HG\u2009+\u2009OA). CA was administered at low (5 \u00b5M) and high (25 \u00b5M) concentrations prior to HG\u2009+\u2009OA treatment. CA significantly enhanced neuronal viability and restored the expression of neurogenesis markers (Nestin, DCX, NeuN) and synaptic proteins (PSD-95, Synaptophysin). Furthermore, CA elevated antioxidant enzyme levels (Nrf2, catalase, SOD-1), regulated apoptosis through increased Bcl-2 and decreased BAX expression, and attenuated inflammatory responses. Pyroptosis was also suppressed, as evidenced by reduced gasdermin D (GSDMD) expression. These findings suggest that CA confers multifactorial neuroprotection against glucolipotoxic injury, and may serve as a dietary modulator for mitigating diabetes-associated cognitive decline in vitro.\n\nID: 42199117\nTitle: An integrated single-nucleus ribonucleic acid sequencing and spatial transcriptomic atlas reveals stage-specific neuronal and glial trajectories in a mouse model of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a progressive multifocal neurodegenerative condition involving motor neurons and other cell types. To analyze spatiotemporal cellular dynamics in amyotrophic lateral sclerosis, we performed single-nucleus ribonucleic acid sequencing and spatial transcriptomics analysis of cervical spinal cords from wild-type control mice and SOD1-G93A transgenic mice in the pre-symptomatic (d50), early symptomatic (d90), and late-stage (d130) phases of disease. Single-nucleus ribonucleic acid sequencing identified 17 cell clusters and showed that progressive neuronal loss occurred over time, paralleled by glial expansion. Spatial transcriptomics mapped these clusters anatomically onto oligodendrocytes in white matter, neurons in horns, and diffuse astrocytes/microglia. Subcluster analysis demonstrated neuronal heterogeneity, with early mitochondrial stress in ventral motor neurons evolving into synaptic dysfunction, transient maturation peaks in interneurons, and amplified age-related decline in amyotrophic lateral sclerosis. Astrocyte and oligodendrocyte subclusters, which were originally misclustered due to spot-level contamination, were reinterpreted to highlight A1-reactive states and progenitor expansions, validated by immunohistochemistry detection of serum/glucocorticoid regulated kinase 1. Temporal profiles tracked the transition from compensatory to inflammatory gliosis, while gene signatures were linked to human amyotrophic lateral sclerosis cohorts, including complement activation and mitochondrial dysfunction. This study provides a high-resolution spatiotemporal cellular map of amyotrophic lateral sclerosis pathogenesis through the integration of single-nucleus and spatial transcriptomics, uncovering early mitochondrial impairment in neurons, delineating the trajectory of neurotoxic glial states, and identifying compensatory progenitor responses, to highlight the highly intricate interaction between glial reactivity and neuronal susceptibility that drives the pathogenesis of ALS.\n\nID: 42194024\nTitle: Activation of the Nrf2/ARE Pathway Attenuates BDE-47-Induced Immunotoxicity in RAW264.7 Macrophages.\nAbstract: Polybrominated diphenyl ethers (PBDEs), widely used as brominated flame retardants, are known to exert persistent adverse effects on the immune systems of humans and other organisms. Previous studies have demonstrated that 2,2',4,4'-tetrabromodiphenyl ether (BDE-47), a prevalent congener, induces apoptosis, impairs phagocytic function, and triggers aberrant immune-inflammatory reactions in RAW264.7 macrophages via the induction of elevated intracellular reactive oxygen species (ROS). However, the underlying regulatory mechanism remains unclear. The nuclear factor erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE) signaling pathway is a key cellular defense system against oxidative stress. In this study, we investigated the role of the Nrf2/ARE pathway in BDE-47-induced macrophage immunotoxicity. Network toxicology analysis identified Nrf2 as a hub gene within the BDE-47-associated immunotoxicity network. Molecular docking and molecular dynamics simulations suggested a potential interaction between BDE-47 and the Keap1-Nrf2 complex, with moderate binding affinity. Experimental studies in RAW264.7 cells showed that BDE-47 exposure activated the Nrf2/ARE pathway, as evidenced by Nrf2 nuclear translocation and the differential upregulation of downstream genes (GCLC, GCLM, HO-1, NQO1, SOD1, and CAT). Importantly, Nrf2 knockdown via lentiviral shRNA or pharmacological inhibition with brusatol significantly exacerbated BDE-47-induced apoptosis and immune dysfunction, including enhanced pro-inflammatory cytokine production and impaired phagocytosis. These results demonstrate that Nrf2/ARE pathway activation represents an adaptive antioxidant response and contributes to limiting BDE-47-induced cytotoxicity and immune impairment in macrophages.\n\nID: 42190857\nTitle: Neurodevelopmental and behavioral effects of early-life esketamine hydrochloride exposure in zebrafish (Danio rerio).\nAbstract: Esketamine hydrochloride is increasingly used as a rapid-acting antidepressant, and its expanding clinical and non-medical use has raised concerns regarding its release into aquatic systems via wastewater treatment plant effluents as an emerging psychoactive contaminant. However, its potential neurodevelopmental toxicity in aquatic organisms remains insufficiently characterized. In this study, zebrafish embryos were exposed to esketamine hydrochloride during early development, and its toxic effects were evaluated using an integrated framework combining developmental, behavioral, histological, transcriptomic, oxidative stress-related, and apoptosis-related endpoints. Early-life esketamine exposure altered multiple developmental indicators, including head length, eye depth, interocular distance, and body length, and disrupted locomotor regulation at later stages, particularly light-dark responsiveness and spatial preference. Histological examination further revealed exposure-related alterations in brain tissue organization. Transcriptomic profiling identified coordinated changes in pathways associated with redox homeostasis, protein synthesis, and phototransduction-related signaling. Targeted validation demonstrated significant upregulation of oxidative stress-related genes, including sod1 and sod2, while ELISA-based assays showed exposure-dependent alterations in SOD, CAT, GSH, and MDA levels. Acridine orange (AO) staining showed increased apoptosis-related fluorescence signals in the head region, with AO-positive puncta density differing significantly among groups. Integrative correlation analysis further linked developmental, behavioral, oxidative stress-related, and apoptosis-related endpoints. Notably, these effects occurred in the absence of overt lethality. Collectively, these findings demonstrate that esketamine interferes with neurodevelopmental and behavioral processes in zebrafish larvae and support the incorporation of early-life neurobehavioral endpoints into risk assessment frameworks for neuroactive pharmaceuticals.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n  --- END ACTUAL ABSTRACT FOR 42399152 ---\n\n- ERROR: You cited ID: 42458007 for the quote: \"The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline.\"\n  FACT: Strict Misquote Detected!

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS.

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n  --- END ACTUAL ABSTRACT FOR 42489267 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy.\" (Source: 42406382)\n- \"Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species.\" (Source: 42398690)\n- \"This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency.\" (Source: 42384233)\n- \"Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model.\" (Source: 42447123)\n- \"In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers.

Diagnostic practices have transitioned to universal testing for both familial and sporadic ALS, supported by the approval of gene-targeted therapies. Mechanistically, research has moved beyond simple oxidative stress models, identifying mutant SOD1 as a catalyst for reactive oxygen species generation and exploring the roles of microglial phagocytosis and SOD1-mediated protein misfolding in disease progression.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe landscape of SOD1-linked ALS management has undergone a paradigm shift, characterized by the integration of proactive genetic testing and personalized medicine. Recent clinical data and mechanistic studies confirm that SOD1 mutations drive complex pathogenesis involving neuroinflammation, excitotoxicity, and protein misfolding. \"Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025.\" This reflects the increased availability of targeted treatments such as tofersen, whose clinical distribution has been confirmed in human autopsy tissues. \"For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy.\" Furthermore, research has refined our understanding of motor neuron resilience: \"These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Biomarker Evolution:** Neuromuscular ultrasound now provides non-invasive diagnostic capabilities that match or precede traditional electroneurographic markers in SOD1G93A models.\n*   **Mechanism Redefined:** Mutant SOD1 acts as both a Fenton-like catalyst for hydroxyl radical generation and a hydrogenation catalyst for hydrogen scavenging.\n*   **Genetic Prevalence:** Population-specific data, such as that from Indian cohorts, demonstrate that SOD1 is the predominant cause of familial ALS, even when other repeat expansions (e.g., C9orf72) are present at low frequencies.\n*   **Systemic Involvement:** ALS motor neuron disease is increasingly viewed as a multisystem disorder where innate immune crosstalk, specifically between cGAS-STING and NLRP3 inflammasomes, drives progression.\n*   **Proactive Planning:** Nationwide adoption of genetic testing in Canada was significantly accelerated by proactive planning during the clinical trial phase of gene-targeted therapies.\n*   **Microglial Dynamics:** SGK1 has been identified as a key regulator of microglial phagocytosis; its inhibition attenuates motor deficits, suggesting it as a potential therapeutic target.\n*   **Future Demand:** Projections indicate a significant increase in ALS clinic visits among asymptomatic gene carriers, requiring substantial expansion of clinical infrastructure by 2035.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression. These findings suggest that longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study.

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria.

The P66R mutation in SOD1 destabilizes local structure and promotes \u03b2-sheet-driven fibrillation, which makes it a suitable model for exploring approaches for reducing pathogenic aggregation. Here, we evaluate silymarin, a polyphenolic compound with known antioxidant and neuroprotective properties, for its potential to inhibit P66R-hSOD1 aggregation. ThT fluorescence and transmission electron microscopy analyses demonstrate a significant decrease in amyloid fibril formation in the presence of silymarin; in addition, FTIR spectroscopy confirms the suppression of \u03b2-sheet formation. Fluorescence quenching and ANS binding assays indicate a moderate-affinity binding between silymarin and the mutant protein, along with a reduction in surface hydrophobicity. Hemolysis assays confirm its protective effect against membrane damage induced by aggregates, while molecular docking and dynamic simulations indicate that silymarin stabilizes aggregation-prone areas with hydrogen bonding and hydrophobic interactions, thereby promoting compact conformations and reducing solvent-exposed surfaces. The findings identified silymarin as an effective anti-amyloidogenic agent that reduces \u03b2-sheet accumulation and fibril formation while also decreasing cytotoxicity, highlighting its potential as a therapeutic candidate for ALS."

Here, we present SKALE 2.0, a phase-resolved geometric deep learning framework that represents proteins as multimodal structural graphs and learns mutation-induced aggregation phenotypes directly from three-dimensional topology. Across SOD1, TDP-43, MAPT, and PRNP, SKALE 2.0 recovered a conserved latent transition from nucleation to elongation while resolving distinct mutation-specific phase sensitivities. Representative protein language model, AlphaFold-derived feature, and non-phase-aware structural baselines failed to recover both phase-dependent mutation modulation and phase separability, indicating that explicit phase conditioning is essential. The learned geometry showed that nucleation is preferentially coupled to buried hydrophobic perturbations, whereas elongation is shaped by solvent-accessible interfaces that support fibril propagation. This framework explains how pathogenic variants can remain globally folded yet acquire aggregation competence through localized structural rewiring. Recombinant SOD1 experiments validated predicted suppressor, enhancer, and phase-switch mutations, demonstrating that initiation and propagation can be tuned independently. SKALE 2.0 links atomic topology to phase-specific assembly kinetics and enables a constraint-aware design of aggregation suppressors."

Several recent genetic studies have found disease-causing variants in 50%-85% of patients with fALS and 10%-15% of those with sALS. The aim of our study is to review our clinical experience with sponsored genetic testing (i.e., pharmaceutical company-sponsored and cost-free to patient) since its inception. We reviewed the medical records on all ALS patients seen at our Center who consented to sponsored genetic testing from August 2021 through October 2025. Of the 170 medical records reviewed, 22 patients (12.9%) tested positive for a disease-causing variant in a known autosomal dominant disorder. Thirteen of 35 patients with fALS (37.1%) were found to have a disease-causing variant, in contrast to 9 of 135 patients (6.7%) with sALS. Of the 22 disease-causing variants found, the following genes were involved in decreasing frequency: C9orf72 11 (50%), SOD1 6 (27.3%), FUS 2 (9.1%), and one each (4.5%) of SQSTM1, TARDBP, and TBK1. Twenty-eight patients (16.5%) harbored 29 variants of uncertain significance (VUS). Results of testing led to medically actionable activities including genetic counseling for patients and at-risk family members with positive results, and treatment (i.e., intrathecal tofersen) for the two patients harboring pathogenic SOD1 variants. The lower diagnostic yields than previously published for fALS and sALS patients likely are related to lower numbers of genes tested in the sponsored genetic panels, and these are expected to improve as more genes are added."

While ASO-mediated SOD1-lowering therapy remains a primary focus, efficacy is being evaluated through longitudinal multi-analyte profiling, including NfL, GFAP, and UCHL-1. Research is increasingly addressing the biological limitations of SOD1-targeting in non-SOD1 disease, the role of oligogenic susceptibility, and the emergence of \"hydrogen therapy\" and immune-modulatory candidates as adjuncts to standard care.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic landscape for SOD1-ALS is characterized by the validation of gene-targeted platforms and the concurrent recognition of the disease's heterogeneous molecular nature. Recent longitudinal studies emphasize that \"longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.\" The mechanistic underpinnings of motor neuron loss in these models are increasingly attributed to the dual role of mutant SOD1, wherein \"mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species.\" Clinical management is shifting toward early detection via non-invasive modalities, as \"Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests.\" Furthermore, the potential for non-SOD1 pathology requires rigorous biomarker assessment, as evidence indicates that \"the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The application of magnesium-silicide based hydrogen gas release serves as an innovative strategy to intercept the crosstalk between oxidative stress and neuroinflammation.\n*   The use of Platelet Factor 4 (PF4) demonstrates a selective neuroprotective benefit in SOD1-driven ALS, bypassing PINK1-dependent mechanisms to restore proteostasis.\n*   The phenomenon of macrophage inclusions (\"tofersenophages\") in CSF has been identified as a persistent, albeit clinically ambiguous, finding during ASO therapy, which surprisingly correlates with favorable clinical outcomes.\n*   Neuromuscular ultrasound serves as a high-sensitivity, non-invasive biomarker that detects disease pathology at stages prior to electroneurographic abnormalities.\n*   Genetic testing for ALS has achieved near-universal integration in clinical practice by 2025, with sponsored, cost-free testing panels significantly increasing diagnostic yields in sporadic cases.\n*   The identification of the JAK2 gene as a novel genome-wide significant signal in the Indian cohort underscores the importance of population-specific genetic surveying.\n*   The integration of phase-resolved geometric deep learning (SKALE 2.0) now allows for the constraint-aware design of aggregation suppressors that differentiate between nucleation and elongation phases.\n*   The existence of oligogenic models (e.g., ATXN2/NEK1) highlights the complexity of ALS, where pathogenicity may be governed by the synergy of multiple low-penetrance variants rather than monogenic drivers.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Glabridin (Glab), a natural flavonoid derived from licorice, has been shown to mitigate stress-related damage due to its antioxidant properties. This study aims to assess the impact of Glab on OS-induced damage in the bovine immortalized cell line (BIECs-21), validate its effectiveness in vivo, and elucidate the underlying mechanisms. The in vitro OS model of BIECs-21 was established using 400 \u03bcM H2O2. The study evaluated cell viability, lactate dehydrogenase (LDH) activity, oxidative markers, inflammatory responses, and apoptosis in BIECs-21 under various treatment conditions. Additionally, the effects of Glab were investigated in a murine model of experimental colitis induced by dextran sulfate sodium (DSS). Glab improved cell viability, reduced LDH release, and mitigated the adverse effects of H2O2 on total anti-oxidation capacity (T-AOC), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) levels. qRT-PCR analysis revealed that H2O2 exposure resulted in decreased expression of nuclear factor erythroid 2-related factor 2 (Nrf2), superoxide dismutase 1 (SOD1), NADPH quinine oxidoreductase-1 (NQO1), and heme oxygenase-1 (HO-1), while it increased the expression of nuclear factor-kappa B (NF-\u03baB), tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-6 (IL-6), and interleukin-8 (IL-8), ultimately leading to apoptosis in BIECs-21. Notably, Glab supplementation partially reversed these effects. Similar benefits of Glab were observed in a DSS-induced colitis mouse model. Glab reduces OS-induced apoptosis in vitro and in vivo by enhancing antioxidant capacity and reducing inflammation.\n\nID: 42489267\nTitle: A Blood-Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN-Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1.\nAbstract: Peripheral factors that systemically regulate amyotrophic lateral sclerosis (ALS) have remained elusive-until now. Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n\nID: 42484074\nTitle: SOD1-lowering therapy for patients with wildtype SOD1-ALS: a case report.\nAbstract: Background and Objectives: To describe clinical and biomarker experience using an SOD1 antisense oligonucleotide (ASO) in a patient with non-SOD1 amyotrophic lateral sclerosis (ALS). Methods: Case report. Results: In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease. The time from symptom onset to death was 9\u2009months. Discussion: While treatment was initiated relatively late (\u223c7\u2009months) after symptom onset and follow-up duration was short, the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.\n\nID: 42480869\nTitle: Macrophage responses to and elevated antibody levels against Chlorovirus ATCV-1 in ALS patients.\nAbstract: Acanthocystis turfacea chlorella virus 1 (ATCV-1) is a giant virus that is part of the human oral microvirome. Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease.\n\nID: 42479071\nTitle: Effects of six weeks of hypoxia and hypoxic SIT on oxidative stress and myokine responses in skeletal muscle of high-fat-fed ApoE-/- mice.\nAbstract: Atherosclerosis-induced oxidative stress drives skeletal muscle myopathy in peripheral artery disease, yet the combined effects of hypoxia and hypoxia sprint interval training (SIT) remain unclear. The present study was designed to evaluate how a six-week regimen of hypoxia exposure and SIT influences redox balance and myokine production in the skeletal muscle of high-fat diet (HFD) (21% fat, 1.5% (w/w) cholesterol; 43% (w/w) sucrose-free carbohydrate, 4.554\u00a0kcal/g)-fed atherosclerotic ApoE-/- mice. Forty male ApoE-/- mice fed a HFD were randomly assigned to four groups: Control-Normoxia, Control-Hypoxia, SIT-Normoxia, and SIT-Hypoxia. The hypoxia protocol involved exposures to 11.2% oxygen three times (40\u00a0min each) per week. Key assessment parameters included plasma lipid profiles, skeletal muscle reactive oxygen species (ROS), protein carbonyls, key components of the Nrf2 antioxidant pathway, glutathione metabolism, and myokine-related markers. Compared with the control group, both hypoxia and SIT-Normoxia significantly reduced levels of ROS, protein carbonyls, and Vegfa165 mRNA expression in the skeletal muscle. Hypoxia alone enhanced the levels of GSH-synthesizing enzymes and promoted myokine production. SIT-Normoxia improved plasma lipid profiles, activated the Nrf2 pathway, enhanced the GSH system, and upregulated myokines. SIT under hypoxia further reduced ROS and Vegfa165 while increasing plasma HDL-C and levels of SOD1 protein in the skeletal muscle, but failed to synergistically activate the Nrf2 pathway or enhance GSH production. Paradoxically, both intervention combinations suppressed the mRNA expression of myokine precursor Fndc5, BAIBA-synthesizing enzyme Hadh and Hadha. Overall, six weeks of isolated hypoxia exposure or SIT training independently reduced oxidative stress and promoted beneficial myokine responses in the skeletal muscle of ApoE-/- mice fed a HFD. The wild-type (WT) mice fed a low-fat diet (LFD) was included to validate successful induction of hyperlipidemia, vascular remodeling, and skeletal muscle oxidative stress in ApoE-/- mice after six weeks of HFD feeding.\n\nID: 42469634\nTitle: Secretory leukocyte protease inhibitor (SLPI) attenuates TLR4/NF-\u03baB-mediated neuroinflammation in amyotrophic lateral sclerosis: a candidate molecule associated with neuro-pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons. While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.\n\nID: 42467070\nTitle: Pivotal Factors in Breast Cancer Molecular Subtypes Apoptosis Induction by ELF-EMF; Ki-67, ROS Level, HER-2, and SODs.\nAbstract: Although increasing research has shown that extremely low-frequency electromagnetic fields (ELF-EMFs) specifically trigger PCD through the elevation of ROS levels in cancer cells, there is no adequate evidence to determine the exact mechanisms of this phenomenon. The antioxidant machinery may play a crucial role in this area; however, this has been neglected in previous research. The main aim of this study was to assess the effect of ELF-EMF exposure (5\u2009days, 1\u2009Hz, 100\u2009mT, 2\u2009h/day) on ROS levels, expression levels of antioxidant genes, and apoptosis induction in different breast cancer molecular subtypes with different p53 statuses. DCFH-DA results revealed that the ROS level increased in all three cell lines (SKBR-3, MDA-MB-231, and MCF-7); this increase was much greater in SKBR-3 (up to 5-fold compared to its sham exposure). This result was concurrent with the annexin V/PI results; SKBR-3\u2009cells showed much more apoptosis induction (about 78%), compared with the others (22% or 11% in the other two cells). On the other hand, the mRNA expression level of SOD1 and SOD2 increased significantly in the MDA-MB-231, in addition to these two genes, the expression level of SOD3 and GSR increased in the MCF-7\u2009cells but not in the SKBR-3. Taken together, our results confirmed that ELF-EMF induced ROS-dependent apoptosis, especially in HER-2-enriched breast cancer cells (the SKBR-3), in a p53-independent manner. Other molecular subtypes (MDA-MB-231 as TNBC, or MCF-7 as luminal A) showed resistance against the ROS level increasing and subsequent apoptosis induction by using antioxidant genes, especially SOD1.\n\nID: 42465739\nTitle: Development and efficacy of ex vivo expanded autologous regulatory T cells for the treatment of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited therapeutic options, in which neuroinflammation critically drives disease progression. Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.\n\nID: 42458007\nTitle: Oligonucleotide-siRNA conjugate for SOD1 amyotrophic lateral sclerosis: a phase 1 trial.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease partly caused by gain-of-function mutations in superoxide dismutase 1 (SOD1). Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS.

However, the global transcriptomic landscape underlying stress-induced hepatic injury remains incompletely understood. In this study, we employed a methionine-choline-deficient (MCD) diet-induced murine model to characterize the phenotypic and transcriptomic alterations associated with liver injury. Male C57BL/6J mice were fed either a control or MCD diet, and hepatotoxicity was assessed by survival analysis, body and liver weight measurements, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, histopathological examination, RNA sequencing, quantitative real-time PCR (qRT-PCR), and tumor necrosis factor-alpha (TNF-\u03b1) enzyme-linked immunosorbent assay (ELISA). MCD feeding markedly reduced survival and body weight while inducing hepatomegaly and significant elevations in serum ALT and AST, indicating severe hepatocellular injury. Histopathological analysis demonstrated hepatic steatosis, hepatocellular ballooning, and lobular inflammation without histological evidence of fibrosis. Transcriptomic profiling revealed extensive gene expression remodeling, characterized by activation of inflammatory pathways, enrichment of MAPK-related signaling, dysregulation of lipid metabolism, suppression of antioxidant defense systems, impairment of cytochrome P450-mediated detoxification, and upregulation of apoptosis-associated genes. qRT-PCR further validated the differential expression of representative genes involved in inflammatory signaling (Tlr4, Nfkb1, Nlrp3, and Casp1), MAPK signaling (Fos), xenobiotic metabolism (Cyp4f18), lipid metabolism (Apoa4 and Lpl), extracellular matrix remodeling (Mmp12), and oxidative stress responses (Sod1 and Gstp1). In addition, elevated serum TNF-\u03b1 levels provided protein-level evidence supporting activation of the TLR4/NF-\u03baB/TNF-\u03b1/NLRP3 inflammatory axis. Although fibrosis-associated transcriptional responses were detected, the absence of histological fibrosis suggests transcriptional priming of fibrogenic pathways rather than established fibrogenesis. Collectively, these findings provide a transcriptomic framework linking oxidative stress, impaired detoxification, inflammatory activation, and stress-responsive signaling to MCD-induced hepatic injury. The MCD model provides a valuable experimental platform for characterizing hepatic stress-response transcriptomes and for generating hypotheses that can subsequently be evaluated in environmentally relevant toxicological models. Nevertheless, caution should be exercised when extrapolating these findings to obesity-associated human MASLD, as the MCD model lacks key metabolic features of the human disease, including obesity and insulin resistance. Therefore, the present findings should be interpreted primarily as transcriptomic signatures of stress-induced hepatic injury rather than as a direct representation of the pathophysiological processes underlying human obesity-associated MASLD.\n\nID: 42450273\nTitle: Microvesicle-Derived Redox Signatures as Mediators of Endothelial Dysfunction in Diabetes.\nAbstract: Chronic hyperglycemia and excessive reactive oxygen species (ROS) production are defining features of endothelial dysfunction, a key driver of diabetic vascular complications such as diabetic nephropathy. Microvesicles (MV-enriched fraction), a subtype of extracellular vesicles, and the stress-responsive antioxidant protein Sestrin2 (SESN2) have emerged as important contributors to these processes. This study investigated the role of the MV-enriched fraction in endothelial cell communication under diabetic conditions, with a particular focus on oxidative stress signaling. To model diabetic injury, EA.hy926 endothelial cells were treated with methylglyoxal (MGO), and the resulting MV-enriched fraction was isolated and then applied to two recipient models: na\u00efve endothelial cells and SESN2 knockdown (KD) cells. Protein expression of key antioxidant markers, including endothelial nitric oxide synthase (eNOS), was assessed by Western blot. Nitric oxide (NO) bioavailability was quantified via nitrite measurement using 2,3-diaminonaphthalene (DAN), while mitochondrial and cytosolic ROS levels were evaluated using MitoSOX and dihydroethidium (DHE), respectively. Results demonstrated that the MV-enriched fraction derived from diabetic conditions triggers a complex antioxidant response in healthy endothelial cells, characterized by upregulation of SESN2, superoxide dismutase 1 (SOD1), and heme oxygenase-1 (HO-1). This suggests a compensatory mechanism that mitigates oxidative stress. Notably, SESN2 KD cells exhibited increased ROS production and reduced NO levels upon MV treatment, underscoring the essential role of SESN2 in maintaining redox homeostasis. Overall, this study highlights the dual role of the MV-enriched fraction as a mediator of both protective and detrimental redox signaling in diabetic endothelial dysfunction and suggests potential therapeutic targets for managing diabetic vascular complications.\n\nID: 42450113\nTitle: Serum Copper-to-Zinc Ratio and Oxidative Stress Are Associated with Anemia in Older Adults with Cardiovascular-Kidney-Metabolic Syndrome.\nAbstract: Chronic oxidative stress is a molecular hallmark of cardiovascular-kidney-metabolic (CKM) syndrome, yet its contribution to CKM-associated anemia beyond erythropoietin deficiency and iron restriction is poorly characterized. The serum copper-to-zinc (Cu/Zn) ratio reflects impaired Cu/Zn-SOD1 antioxidant capacity and inflammatory trace-element imbalance, but its relationships with circulating redox biomarkers and its hematological relevance in CKM syndrome has never been explored in a community-dwelling cohort of older adults. We analyzed 2391 NHANES 2011-2016 participants \u2265 50 years of age with CKM stage I-IV. To explore whether the serum Cu/Zn ratio was associated with oxidative stress and immunomodulatory biomarkers as well as with the odds of anemia, we used survey-weighted Spearman correlations, linear regression (outcome: hemoglobin), and logistic regression (outcome: anemia); multivariate models were adjusted for a panel of antioxidant or immunomodulatory biomarkers (selenium, vitamin D), pro-oxidant biomarkers (lead, cadmium, cotinine, uric acid), red cell distribution width (RDW) as a composite biomarker of erythrocyte stress, neutrophil-to-lymphocyte ratio (NLR), CKM stage, and comorbidities. The molecular targets of the nine biomarkers were mapped onto a protein-protein interaction network using the STRING database v12.0 to contextualize regression findings within a systems biology framework. Anemia was present in 205 participants (8.6%). The Cu/Zn ratio was inversely correlated with the antioxidant marker selenium (r = -0.19; p < 0.001) and positively correlated with the pro-oxidant markers RDW (r = +0.21; p < 0.001) and cadmium (r = +0.10; p < 0.001), consistent with its role as a hub within the CKM redox network. In fully adjusted models, a higher Cu/Zn ratio was independently associated with prevalent anemia (OR = 2.94; 95% CI: 1.61-5.37) and lower hemoglobin (\u03b2 = -0.55 g/dL); among included biomarkers, selenium and cadmium were independently protective (OR = 0.76 per 10 \u00b5g/L and 0.23 per \u00b5g/dL, respectively), and RDW and uric acid were independently harmful (OR = 2.20 per 1% and 1.33 per mg/dL, respectively). The Cu/Zn ratio correlated with both antioxidant depletion and pro-oxidant accumulation in CKM syndrome and was independently associated with anemia within this oxidative network. Together with selenium, cadmium, RDW, and uric acid, it defines an oxidative stress-driven hematological pathway that may contribute to the development and progression of anemia in patients with CKM syndrome.\n\nID: 42447970\nTitle: Human umbilical cord-derived mesenchymal stem cells ameliorate muscle dysfunction and metabolic dysregulation in the CuZnSOD null mouse model of sarcopenia.\nAbstract: Age-related sarcopenia is a progressive skeletal muscle disorder driven by oxidative stress and metabolic dysregulation. Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.\n\nID: 42447123\nTitle: Neuromuscular ultrasound as a biomarker in the SOD1 mouse model of amyotrophic lateral sclerosis.\nAbstract: A progression marker that indicates early disease-related changes and treatment responses in the to date incurable neurodegenerative disease amyotrophic lateral sclerosis (ALS) is highly desirable. Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.\n\nID: 42442802\nTitle: The Role of Genetic Alterations in the Emergence of Alzheimer's Disease in Down Syndrome: A Review.\nAbstract: Down syndrome (DS), the most common chromosomal disorder, is associated with an accelerated aging process, increasing the risk of early-onset Alzheimer's disease. This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers.\n\nID: 42442304\nTitle: Amelioration of obesity-induced testicular dysfunction and structural damage by ganoderma lucidum polysaccharides and triterpenoids in rats: Correlation with Nrf2-mediated antioxidant response.\nAbstract: Obesity is a global health crisis and a critical risk factor for male infertility, impairing testicular structure and function through hormonal imbalance and oxidative stress. Current therapeutic strategies are often unsatisfactory due to limited efficacy or adverse effects. This study investigated the protective effects and potential molecular mechanisms of Ganoderma lucidum (GL) polysaccharides and triterpenoids against testicular injury in high-fat diet-induced obese male rats. After 12-week GL intervention, reproductive function in obese male rats showed improvement: GL increased litter size, improved sperm motility, reduced sperm DNA fragmentation, and restored serum testosterone, inhibin B, and leptin levels. It also alleviated testicular histopathological damage, downregulated PPT1, and maintained vimentin expression. Notably, GL facilitated delayed fertility recovery and showed a trend toward improved cumulative reproductive success, although fixed-time pregnancy rates were not significantly changed. Mechanistically, GL is associated with enhanced Nrf2 pathway activity, increased SOD1, HO-1, NQO1, and GPX4 levels, and decreased MDA and ROS accumulation, thereby attenuating oxidative stress. It preserved mitochondrial integrity, suppressed germ cell apoptosis (downregulating Bax and caspase-3, upregulating Bcl-2), and promoted cell proliferation. These findings indicate that GL polysaccharides and triterpenoids effectively ameliorate obesity-induced testicular dysfunction, and these beneficial effects are associated with Nrf2-mediated antioxidant responses, mitochondrial homeostasis, apoptosis regulation, and hormonal balance. GL may serve as a promising candidate for obesity-related male infertility.\n\nID: 42437952\nTitle: NOP56 is essential for mammalian generation and maintenance of multiple central nervous systems, associated with SCA36 pathology.\nAbstract: NOP56, a core nucleolar component involved in small nucleolar ribonucleoprotein assembly, has been genetically implicated in spinocerebellar ataxia type 36. However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097.\n\nID: 42432986\nTitle: Mitoquinone Prevents Cardiac Dysfunction by Normalizing Mitochondrial ROS and Calcium Handling in Acute Myocardial Infarction.\nAbstract: Acute myocardial infarction (MI) is the leading cause of heart failure (HF). However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI. Male Wistar rats were divided into four experimental groups: Sham, Infarct, Sham+MitoQ, and Infarct+MitoQ. MitoQ was administered orally (8\u2009mg/kg/dia) for 7\u2009days. Hemodynamic parameters, infarct area, papillary muscle contractility, cardiomyocyte mechanics, Ca2+ transients, and total and mitochondrial superoxide (DHE and MitoSOX) were assessed. After 7\u2009days of MI, rats exhibited impaired contractility, altered inotropic response to extracellular Ca2+, cardiomyocyte hypertrophy, and increased total and ROSm. MitoQ prevented body weight loss and significantly improved hemodynamic parameters compared to the Infarct group. In papillary muscles, MitoQ restored basal isometric force and the inotropic response to extracellular Ca2+. In cardiomyocytes, it attenuated hypertrophy, preserved shortening, and reduced ([Ca2+]i) transient amplitude. MitoQ significantly decreased total and mitochondrial O2\u2022- production. It selectively reduced NOX1 expression under simulated conditions but did not significantly affect NOX2, SOD1, or catalase expression in the context of MI. MitoQ prevented contractile dysfunction, suggesting that mitochondrial oxidative stress plays a decisive role in myocardial dysfunction during the acute phase of MI. Targeting antioxidant therapy to the mitochondria represents a promising strategy for preventing post-infarction heart failure and opens new perspectives for the development of more effective interventions in the treatment of cardiovascular diseases.\n\nID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the \u03b11 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.\n\nID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.\n\nID: 42425334\nTitle: Comparative screening of Amur tiger cytokines identifies IL-15 as a cytoprotective candidate against feline panleukopenia virus infection.\nAbstract: Comparative studies of species-derived cytokines remain limited in endangered carnivores. We cloned six immune-related cytokines from Amur tigers (Panthera tigris altaica), with sequence analysis revealing >90% identity across Felidae. Among all tested cytokines, IL-15 demonstrated superior and sustained lymphocyte-stimulatory activity at 200\u202fng/mL. To investigate antiviral potential, F81\u202fcells were pretreated with IL-15 and challenged with feline panleukopenia virus (FPV). Mechanistic studies revealed that IL-15 attenuated virus-induced apoptosis by modulating key regulatory proteins: downregulating pro-apoptotic factors (Bax, Caspase3/9, p53, Cytc) while upregulating anti-apoptotic Bcl-2. Additionally, IL-15 preserved mitochondrial integrity by maintaining membrane potential, enhancing fusion proteins (MFN1/MFN2), and suppressing fission protein Drp1. IL-15 also strengthened cellular antioxidant defenses through increased SOD1/SOD2 expression, significantly reducing reactive oxygen species (ROS) accumulation. These protective effects persisted for 48\u202fh post-infection, demonstrating sustained cytoprotective effects. These findings reveal species-specific IL-15-mediated antiviral mechanisms within the Felidae family and provide comparative insights into how immune defenses are optimized in species with constrained evolutionary history, with implications for understanding carnivore immune evolution and conservation medicine.\n\nID: 42419058\nTitle: Redox Imbalance and Impaired Protein Clearance Drive Chronic Liver Injury in Biliary Atresia.\nAbstract: Excessive or uncontrolled generation of reactive oxygen species (ROS) is closely associated with the development of liver diseases. However, direct evidence linking oxidative stress to impaired hepatic function in human biliary atresia (BA) remains limited. To address this, we performed bulk RNA sequencing to investigate (1) alterations in hepatic oxidative stress and antioxidant defense mechanisms and (2) transcriptomic changes associated with impaired hepatic function in BA. Total RNA was extracted from liver samples of patients with BA and non-BA cholestasis. Bulk RNA sequencing and transcriptomic analyses were performed, focusing on redox-related pathways and genes linked to hepatic function. Dual oxidases 1 and 2 were significantly upregulated in BA. In contrast, key ROS-metabolizing enzymes such as catalase, glutathione synthetase, and superoxide dismutase 1 and 2 were downregulated, indicating redox imbalance in BA livers. Excessive ROS can lead to the denaturation of cellular proteins and damage to organelles, which are normally degraded via autophagy and proteasomes. However, both autophagy and proteasome functions were impaired in BA, contributing to sustained inflammation and further ROS production. Transcriptomic analyses also revealed repression of core liver transcription and splicing factors, indicating injury-associated alterations in hepatic transcription programs. BA is characterized by a redox imbalance and dysfunctional protein clearance, forming a vicious cycle of ROS accumulation and inflammation. These changes likely contribute to liver fibrosis and the progressive loss of hepatic function in BA.\n\nID: 42406382\nTitle: Antisense Oligonucleotide Tofersen Distribution in the Central Nervous System of SOD1-ALS Autopsy Tissue Donors.\nAbstract: Tofersen is a disease-modifying antisense oligonucleotide therapeutic for people living with SOD1-amyotrophic lateral sclerosis (SOD1-ALS). Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues.\n\nID: 42402967\nTitle: Hypoxia-preconditioned dental pulp stem cells alleviate acetaminophen-induced liver failure via promoting MYC-HIF1A/HIF-1\u03b1-BNIP3-mediated mitophagy.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is a prevalent clinical liver condition caused mostly by oxidative stress and mitochondrial damage. Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI.

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n\nID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n\nID: 42397005\nTitle: Covalent Modulation of Protein Misfolding and Aggregation Processes in the Context of Neurodegenerative Diseases.\nAbstract: Misfolded protein aggregates represent major histopathological hallmarks of neurodegenerative diseases, differing in the structural components and brain regions affected. Furthermore, the formed assemblies act as key players in developing and fostering neurotoxic processes, with distinct mechanisms depending on the stage of the amyloid cascade. Particularly, the oligomer intermediates are now considered as the main drivers of neurotoxicity, thus requiring an early antiaggregant therapeutic intervention to achieve a significant neuroprotective efficacy. Among different strategies, direct interaction at early stages preventing aggregation is quite intricate due to the considered undruggability of misfolded monomers. In this context, a covalent approach targeting specific functional nucleophilic residues within disordered proteins can offer an intriguing opportunity to overcome these weaknesses. Therefore, in this review, we outline covalent modulators of misfolding and aggregation processes reported to date, referring to the major misfolded proteins in the neurodegenerative context (i.e., \u03b2-amyloid, tau, \u03b1-synuclein, and superoxide dismutase 1) to highlight their potential both as valuable pharmacological tools or therapeutic perspectives.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42390843\nTitle: Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis.\nAbstract: Superoxide dismutase 1 (SOD1), a copper-dependent antioxidant, is essential for redox homeostasis, and its decline drives renal senescence and fibrosis. However, the mechanisms linking profibrotic signaling to SOD1 inhibition remain unclear. Here, we identified a pathological copper-COMMD1-SOD1 axis in which intracellular copper overload paradoxically suppressed SOD1 activity. In kidney tissues from chronic kidney disease (CKD) patients and complementary in vivo and in vitro fibrotic models, we consistently observed a reduction in SOD1 activity accompanied by elevated intracellular copper levels.\u00a0Lowering intracellular copper levels restored SOD1 activity, suppressed reactive oxygen species (ROS) accumulation, and alleviated cell senescence and fibrosis. Mechanistically, pathological copper overload impaired SOD1 homodimerization, the essential final step in its activation. We identified copper metabolism MURR1 domain containing 1 (COMMD1) as a key copper-sensitive mediator of this process. Copper overload acted upstream, simultaneously upregulating COMMD1 expression and enhancing its binding affinity to SOD1. This enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function. Collectively, these findings redefined the regulatory role of copper in SOD1 activity and uncovered a previously unrecognized mechanism by which pathological copper overload paradoxically suppressed SOD1 activity via COMMD1-dependent disruption of SOD1 homodimerization, providing new insight into the pathophysiology of copper dyshomeostasis-associated diseases.\n\nID: 42387584\nTitle: SGK1-mediated deficits in microglial phagocytosis drive pathological progression in amyotrophic lateral sclerosis.\nAbstract: Alterations in microglial function and transcriptomic profiles are major pathological hallmarks of amyotrophic lateral sclerosis (ALS). However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.\n\nID: 42385849\nTitle: Quercetin and carvacrol act synergistically to inhibit Candida albicans biofilms in vitro via membrane disruption and oxidative stress.\nAbstract: Candida albicans biofilms are a major cause of device-associated infections and treatment failure due to high antifungal tolerance. Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200\u202f\u03bcg/mL (carvacrol) and 240\u202f\u03bcg/mL (quercetin) to 17\u202f\u03bcg/mL and 10.9\u202f\u03bcg/mL, respectively (FICI\u202f=\u202f0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by \u223c64.4% (vs. \u223c56.5% for carvacrol and \u223c51.5% for quercetin alone) and inducing apoptosis-like cell death with robust metacaspase activation supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established.\n\nID: 42385392\nTitle: Biological responses of human astrocytes (SVGp12) and glioblastoma (A172) cells to dendronized \u03b2-cyclodextrin molecular containers: Morphological and molecular insights.\nAbstract: The search for molecular containers that enhance the bioavailability of active substances has opened the development of functionalized \u03b2CD-based molecular containers. In this study, the effects of \u03b2CD-modified with dimethylolpropionic acid (Bis-MPA) dendrons (\u03b2CD-m2G and \u03b2CD-m3G) were evaluated in SVGp12 (non-tumor astrocytes) and A172 (glioblastoma) cells. The dendronized systems exhibited low cytotoxicity (>75% viability) even at high concentrations (90\u00a0\u03bcM, p\u00a0<\u00a00.05). Morphological analyses revealed lipid inclusion bodies (LIBs), suggesting that after intracellular uptake, the dendronized containers promote their formation. \u03b2CD-m3G occupies 12% of the cell volume in SVGp12 and 17% in A172 (p\u00a0<\u00a00.05). Ultrastructural evaluation showed increased smooth endoplasmic reticulum (SER), a finding consistent with enhanced lipid metabolism. Importantly, cell differentiation and endoplasmic reticulum stress, evaluated by the expression of Aquaporin-4 and calnexin, were not impaired (p\u00a0>\u00a00.05). A twofold increase in mGlu-5 expression (p\u00a0<\u00a00.001) was observed in both cell lines due primarily to the \u03b2CD-m3G container. Because neither container induces oxidative stress in the SVGp12 cell line, cell proliferation increases from 41% to 48% (p\u00a0<\u00a00.001) due to \u03b2CD-m2G and \u03b2CD-m3G, respectively. These cells also increased Caspase9 expression (p\u00a0<\u00a00.001), suggesting control of proliferation. However, \u03b2CD increased NRF2 expression by 4.3-fold (p\u00a0<\u00a00.0001) and the expression of SOD1, HMOX1, and PRDX1. \u03b2CD increases 1.8-fold-ROS in A172 cells (p\u00a0<\u00a00.001) versus control. 3.5-fold expression of NRF2 was observed in the presence of NAC (p\u00a0<\u00a00.001). These suggest that only \u03b2CD increases NRF2 and ROS as an adaptive response of A172 cells. The incorporation of amphiphilic dendritic groups enables efficient cellular uptake of \u03b2CD-dendronized containers.\n\nID: 42384769\nTitle: Carbon monoxide-releasing vesicles provide rapid and sustained inhibition of inflammatory pain in mice.\nAbstract: Carbon monoxide (CO) is an important modulator of chronic pain, but its clinical use remains limited. To enhance its therapeutic potential, we developed a vesicular CO-releasing system based on a carbonyl metallosurfactant (PCOL6) and soy phosphatidylcholine (SPC) and evaluated its physicochemical properties, as well as its in silico and in vivo effects on inflammation-induced nociception and muscle impairment in male C57BL/6 mice. The metallosomes exhibited a uniform size distribution, stability upon dilution, and a predominantly single membrane, indicating their suitability for therapeutic applications. Computational simulations revealed that PCOL6 can mix with phospholipids to form stable lamellar structures with thinner and more disordered bilayers than those of pure phospholipid membranes. In vivo experiments showed that acute administration of PCOL6/SPC vesicles inhibited complete Freund's adjuvant (CFA)-induced allodynia faster and longer than tricarbonyldichlororuthenium (II) dimer, Ru2Cl4(CO)6 (CORM-2). Repeated metallosome treatment was also more effective than CORM-2 at reducing allodynia, hyperalgesia, and inflammation-related muscle deficits. Both CO releasers normalized CFA-induced NOD-like receptor protein 3 inflammasome overexpression, increased heme oxygenase 1 (HO-1) and NAD(P)H quinone dehydrogenase 1 expression, and maintained elevated superoxide dismutase 1 levels in paw tissues; notably, HO-1 induction was greater in PCOL6/SPC-treated mice. These findings suggest that PCOL6/SPC metallosomes represent a promising therapeutic strategy for chronic inflammatory pain. Vesicles bearing a CO-releasing metallosurfactant (PCOL6) inhibit inflammatory pain.The analgesic effect of PCOL6/SPC is higher and lasts longer than that of CORM-2.PCOL6/SPC exerts anti-inflammatory and antioxidant effects.\n\nID: 42384233\nTitle: Genome-wide spectrum of coding DNA variations in Indian patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited therapies, emphasizing the need for deeper understanding of disease pathogenesis. While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.\n\nID: 42383461\nTitle: Acute Exposure to Environmentally Relevant Concentrations of Ciprofloxacin and Levonadifloxacin Alters Behavior, Organ Health, and Stress Response in Adult Zebrafish.\nAbstract: Antibiotic pollution in aquatic systems is an emerging global concern, but the sublethal effects of acute exposure on aquatic vertebrates are poorly understood. This study examined the acute toxicity by exposing adult zebrafish to three concentrations (1, 5, and 10\u2009mg/L) of ciprofloxacin (CIP) and levonadifloxacin (LND) for 96\u2009h. Behavioral, histological, biochemical, and transcriptional changes were assessed. In the novel tank-dive test, both antibiotics induced concentration- and time-dependent anxiogenic behaviors, such as reduced exploration, decreased total distance traveled, and less time in the upper zone. Histopathological analysis showed progressive tissue damage beginning in the gill epithelium and spreading to the intestine and muscle. Overall, lesion severity increased with higher concentrations and was consistently higher in CIP-exposed fish. Antioxidant enzyme activity exhibited significant changes in superoxide dismutase, catalase, and glutathione peroxidase 1. Early increase in enzyme levels at 48\u2009h coincided with reduced transcription of sod1, cat1, and gpx1a. At 96\u2009h, transcription levels increased while protein levels remained stable. Pathway analysis grouped these genes within interconnected oxidative stress networks rather than cell death pathways. Overall, the results indicate that exposure to both fluoroquinolones for 96\u2009h causes a staged oxidative stress response, along with behavioral disruptions and tissue damage. CIP caused stronger immediate biological effects than LND at the same concentrations, although both antibiotics disturbed organismal homeostasis at sublethal levels. These findings highlight the ecological importance of short-term antibiotic contamination and demonstrate the value of multiple endpoints for detecting early toxic effects in aquatic organisms.\n\nID: 42381517\nTitle: Proteomic Profiling of Cryopreservation-Induced Alterations in Rhesus Macaque Sperm.\nAbstract: Sperm cryopreservation is a fundamental technique in assisted reproductive technologies. While human sperm freezing is clinically routine, preserving nonhuman primate sperm remains challenging due to species-specific characteristics and low post-thaw viability. This study aims to investigate the proteomic changes in rhesus macaque sperm before and after cryopreservation, focusing on identifying the molecular mechanisms behind cryoinjury. Semen was collected from six sexually mature male rhesus macaques (6-10 years) using rectal electroejaculation. Motility parameters were quantified pre- and postcryopreservation using computer-assisted semen analysis (CASA) with vapor-phase liquid nitrogen protocols. Data-independent acquisition (DIA) quantitative proteomics, combined with LC-MS/MS, was used to profile global protein expression changes. Differential protein analysis was performed using multibioinformatics tools for functional annotation and network modeling. Papanicolaou and acridine orange (AO) staining were used to assess sperm morphology and DNA integrity, while reactive oxygen species (ROS) assay and immunofluorescence were employed to validate the proteomic analysis results. We identified 512 differentially expressed proteins (32 upregulated, 480 downregulated), which are predominantly enriched in pathways related to metabolic reprogramming, oxidative stress response, and protein homeostasis. Immunofluorescence staining further confirmed markedly reduced levels of SOD1, PGK2, PKC\u2011alpha, and phospho\u2011tyrosine in sperm after freeze-thaw cycling. These molecular hubs are associated with sperm motility and functional stability and may be essential for regulating energy metabolism, oxidative balance, and proteotoxicity during cryopreservation-induced stress in rhesus macaque sperm. Cryopreservation induces profound proteomic remodeling in rhesus macaque sperm, mitochondrial electron transport, and metabolic homeostasis. Our findings reveal conserved and species-specific cryoinjury mechanisms, offering molecular targets for optimizing cryopreservation protocols in nonhuman primates to advance reproductive conservation strategies.\n\nID: 42399593\nTitle: Early and severe masticatory muscle involvement in SOD1-ALS: a case report with biomarker-clinical dissociation.\nAbstract: \n\nID: 42375264\nTitle: Proteomic profile of seminal plasma in tropical Saanen bucks under heat stress using 1D-SDS PAGE.\nAbstract: Tropical heat and humidity induce oxidative and thermal stress that threaten male fertility. However, the seminal plasma mechanisms that sustain sperm function under these conditions in goats remain poorly understood. This study aimed to evaluate semen quality and characterize the seminal-plasma proteome of Saanen bucks raised under Indonesia's tropical conditions to identify molecular adaptations associated with fertility resilience. Three healthy bucks (five ejaculates each) were examined using computer-assisted sperm analysis (CASA) for sperm motility, viability, abnormality, membrane and acrosome integrity, and kinematics. Seminal-plasma proteins were separated by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and annotated through Gene Ontology enrichment. While most semen traits and kinematics were comparable among bucks, abnormality and acrosome integrity differed significantly (p < 0.05). A conserved extracellular, vesicle-associated proteome was identified-including BSP1, BSP3, BSP5, ANXA5, ALB, HSPA1A, HSP90AA1, CLU, GPX5, and SOD1-with minor inter-individual variation in LTF, FN1, SPP1, and A2M. Enrichment (FDR < 0.05) highlighted the extracellular region, vesicle, and cytokine-regulatory pathways. This study provides the first proteomic evidence of seminal plasma adaptation to THS in Saanen bucks, revealing a stable core of chaperone, antioxidant, and membrane-coating proteins that safeguard sperm function. These findings establish a novel proteomic basis for heat-resilient fertility and support the development of protein-based sire selection and reproductive management tools in tropical dairy-goat systems.\n\nID: 42367369\nTitle: Preparing Amyotrophic Lateral Sclerosis Clinics to Provide Longitudinal Care for Individuals Carrying ALS Risk Variants.\nAbstract: Emerging genetic therapies and the expansion of genetic testing are identifying individuals carrying amyotrophic lateral sclerosis (ALS) risk variants who would benefit from surveillance and early intervention. Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care.\n\nID: 42359357\nTitle: Innate immune crosstalk in ALS/FTD pathogenesis.\nAbstract: Marked by protein aggregation, impaired proteostasis, organelle stress, and chronic neuroinflammation, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) form a clinically, genetically, and pathologically overlapping disease spectrum. Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.\n\nID: 42352031\nTitle: Statin-Induced Coenzyme Q Deficiency Induces Metabolic Reprogramming in Astrocytes.\nAbstract: Statins are commonly used cholesterol-lowering drugs, but their effects on astrocyte oxidative metabolism are poorly understood. To investigate this, rat astrocytes were exposed to 200 nM atorvastatin or simvastatin for 6 days and then assessed for changes in coenzyme Q (CoQ) homeostasis, mitochondrial function, and energy metabolism. Both statins comparably decreased cellular CoQ9 and CoQ10 levels (~35%), with greater losses of their reduced antioxidant forms (60-75%). Lower intracellular and mitochondrial levels of reactive oxygen species (ROS) were accompanied by the upregulation of nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant pathways (superoxide dismutase 1 and glutathione reductase) and metabolic stress response factors, including hypoxia-inducible factor 1-alpha (HIF1\u03b1) and brain-derived neurotrophic factor (BDNF). Both statins promoted glycolytic reprogramming, mitochondrial fission, and biogenesis while impairing oxidative phosphorylation, as evidenced by reduced ATP-linked respiration, increased proton leak, and lower ATP levels. These findings suggest that statin-treated astrocytes adapt by prioritizing redox homeostasis over ATP production. CoQ10 supplementation increased cellular CoQ10 levels and restored ATP levels without further decreasing ROS, suggesting that its primary benefit is bioenergetic support, not additional antioxidant protection. Overall, statin-induced CoQ deficiency induces adaptive metabolic remodeling of astrocytes, while CoQ10 supplementation may help maintain energy metabolism under these conditions.\n\nID: 42343420\nTitle: Immune checkpoint LAG-3 governs stage-dependent and disease-associated microglial modules in ALS model mice.\nAbstract: Immune checkpoint molecules, inhibitory receptors originally characterized in T cell biology, have recently emerged as regulators of microglial function in neurodegeneration, yet their roles in amyotrophic lateral sclerosis (ALS) remain unexplored. Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration.\n\nID: 42328125\nTitle: Polyinosinic:polycytidylic acid causes epithelial-mesenchymal transition via BAFF expression in Beas-2B human bronchial epithelial cells.\nAbstract: The bronchial epithelium acts not only as the primary physical barrier but also as an active sensor that responds to exogenous materials such as bacteria and viruses, by producing various cytokines including B-cell activating factor (BAFF). Although BAFF is a well-known protein in B-cell functions, its role in bronchial cell function remains undefined. Polyinosinic-polycytidylic acid (Poly (I:C)), a synthetic double-stranded RNA, serves as a model for viral infection that binds to toll-like receptor (TLR) 3 to trigger intracellular signal pathways. In this study, we investigated the effect of Poly (I:C)-induced BAFF expression on airway cell migration using Beas-2B human bronchial epithelial cells. Poly (I:C) increased BAFF expression and cell migration, along with the increased expression of N-cadherin, Vimentin and Slug (SNAI2), which are three primary markers for epithelial-mesenchymal transition (EMT). Cell migration was attenuated by small interfering RNA (siRNA) against BAFF, which also inhibited the expression of these EMT markers. Phosphorylation of c-Jun N-terminal kinase (JNK) was enhanced by Poly (I:C) and inhibited by SP600125, JNK inhibitor, leading to a decreased expression of BAFF and aforementioned EMT markers. Poly (I:C) increased reactive oxygen species (ROS), resulting in a ROS-dependent up-regulation of antioxidants (Catalase, superoxide dismutase (SOD)1 and heme oxygenase (HMOX)1) and Nrf2. Pre-treatment with N-acetylcysteine (NAC), ROS scavenger, inhibited Nrf2 activation and JNK phosphorylation. The increase in Nrf2 levels induced by Poly (I:C) was also attenuated by SP600125. Additionally, while NAC treatment inhibited BAFF expression, it caused little change in the expression of the three EMT markers. Increased BAFF expression was confirmed by Nrf2 binding to the BAFF promoter or an increase in the luciferase activity of BAFF promoter co-transfected with Nrf2 plasmids. Treatment with recombinant BAFF protein also increased cell migration and EMT marker expression. Taken together, our results demonstrate that Poly (I:C) promotes a regenerative migration of bronchial epithelial cells by inducing BAFF expression through the ROS-dependent JNK-Nrf2 signaling axis.\n\nID: 42327579\nTitle: Assessing the Association Between Genetic Variants in ACE, SOD1, and PER3 and their Role in Breast Cancer Risk among Jordanian Women.\nAbstract: Genetic and environmental factors regulate many physiological processes in the human body, and alterations in these processes may contribute to the development of various diseases, including breast cancer (BC), which is considered the most prevalent cancer among women and a leading cause of cancer-related mortality in the Jordanian population. Genes such as ACE, SOD1 and PER3 play important roles in regulating essential biological functions. These genes are involved in key physiological pathways, including blood pressure regulation, oxidative stress response and circadian rhythm maintenance, and genetic variants within them may influence susceptibility to cancer. Therefore, this study investigates the association between polymorphisms in the ACE, SOD1 and PER3 genes and the risk of breast cancer, with the aim of evaluating how these genetic variations relate to breast cancer susceptibility and clinical outcomes in Jordanian women. Blood samples of 300 women diagnosed with breast cancer, along with 300 healthy participants, were collected, and DNA was extracted from them. Genetic variants in the ACE (rs1799752), SOD1 (rs36232792) and PER3 (rs57875989) genes are examined through employing direct PCR to amplify the target regions. The ACE (rs1799752) variant was observed to be associated with breast cancer susceptibility, with the I/I genotype increasing risk of breast cancer (OR = 5.138, 95% CI = 1.38-19.03, p = 0.014). No associations were observed for SOD1 (rs36232792) and PER3 (rs57875989) variants. The rs1799752 polymorphism is suggested to have the potential of serving as a biomarker for breast cancer susceptibility in Jordanian women, as it is associated with elevating the risk.\n\nID: 42327062\nTitle: Effects of oxidative stress and aging on nerve, muscle, and synapse in a male-specific abdominal neuromuscular junction in Drosophila.\nAbstract: Defects in Drosophila Cu 2+ /Zn 2+ superoxide dismutase (encoded by the gene Sod1 ) lead to elevated oxidative stress and a drastically shortened lifespan. To contrast the effects of aging and oxidative stress on nerve conduction, synaptic transmission, and muscle excitability, we developed an easily accessible adult abdominal neuromuscular preparation, utilizing the male-specific Muscle of Lawrence (MOL) in Drosophila . The large size of MOL facilitated analyses of presynaptic nerve signals and postsynaptic responses that could result in sizable excitatory junctional potentials (EJPs) evoking full-blown muscle action potentials (APs) which were terminated rapidly by a characteristic afterhyperpolarization (AHP). Aged wild-type (WT) individuals (80 days or older) exhibited diminished neuromuscular transmission, mainly reflecting declines in motor axon conduction, with synaptic transmission remaining largely intact (since robust EJPs could still be evoked when nerve terminals were directly stimulated electrotonically). Additionally, muscle APs showed enhanced depolarizing peaks and weakened AHPs during current injection, suggesting weakening in repolarizing K + currents. Chronologically younger Sod1 mutants (up to 30 days) displayed similar trends of neuromuscular changes, confirming a major role of oxidative stress in aging. However, certain distinctions exist in muscle membrane properties and transmitter release machinery. A clear increase in muscle membrane resistance was seen in Sod1 but not in aged WT. Additionally, unlike normal spontaneous release of synaptic vesicles leading to miniature EJPs (mEJPs), extremely enlarged spontaneous transmitter discharges occurred in aged WT but was never seen in Sod1 , indicating a distinct, aging-specific alteration in transmitter release regulation. Notably, our work revealed considerable variation among individuals, ranging from transmission failure to largely intact neuromuscular functions, demonstrating the stochastic nature of functional declines due to aging and oxidative stress. Moreover, this study uncovered a well-defined common vulnerability, i.e. weakening of the Ca 2+ -activated BK current that caused drastic reduction in AHP in both aged WT and Sod1 mutants, as confirmed by their diminishing sensitivity to the BK channel blocker paxilline, which caused striking alterations in the AHP in WT control.\n\nID: 42324839\nTitle: The Impact of Sponsored Genetic Testing in 170 Consecutive Consenting Patients With Amyotrophic Lateral Sclerosis: A Single-Site Retrospective Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is often categorized as sporadic (sALS) or familial (fALS) based on the family history. Several recent genetic studies have found disease-causing variants in 50%-85% of patients with fALS and 10%-15% of those with sALS. The aim of our study is to review our clinical experience with sponsored genetic testing (i.e., pharmaceutical company-sponsored and cost-free to patient) since its inception. We reviewed the medical records on all ALS patients seen at our Center who consented to sponsored genetic testing from August 2021 through October 2025. Of the 170 medical records reviewed, 22 patients (12.9%) tested positive for a disease-causing variant in a known autosomal dominant disorder. Thirteen of 35 patients with fALS (37.1%) were found to have a disease-causing variant, in contrast to 9 of 135 patients (6.7%) with sALS. Of the 22 disease-causing variants found, the following genes were involved in decreasing frequency: C9orf72 11 (50%), SOD1 6 (27.3%), FUS 2 (9.1%), and one each (4.5%) of SQSTM1, TARDBP, and TBK1. Twenty-eight patients (16.5%) harbored 29 variants of uncertain significance (VUS). Results of testing led to medically actionable activities including genetic counseling for patients and at-risk family members with positive results, and treatment (i.e., intrathecal tofersen) for the two patients harboring pathogenic SOD1 variants. The lower diagnostic yields than previously published for fALS and sALS patients likely are related to lower numbers of genes tested in the sponsored genetic panels, and these are expected to improve as more genes are added.\n\nID: 42320547\nTitle: Proteomic analysis reveals early pathological defects in corticospinal motor neurons of a spastin model of hereditary spastic paraplegia, which are improved by NU-9 treatment.\nAbstract: Upper motor neuron (UMN) degeneration is a characteristic feature of hereditary spastic paraplegia (HSP), a genetically heterogeneous heritable neurodegenerative disorder resulting from mutations in over ninety genes. The mutations in the SPAST gene, which encodes the microtubule-severing protein spastin, are responsible for about 40% of all HSP cases. To date, the cellular and molecular mechanisms linking mutant spastin protein to UMN vulnerability in HSP patients remain unknown and there are no disease modifying therapies. To address this knowledge gap, we isolated pure populations of corticospinal motor neurons (CSMN; a.k.a. UMN in mice) from SPASTC448Y-UeGFP reporter mice at two pre-symptomatic time points and performed bottom-up proteomic analyses to reveal changes in their proteome that informs the underlying causes of their initial vulnerability. We find dynamic changes in their proteome and that limitations with cytoarchitectural integrity and stability of key organelles contribute to their neuronal vulnerability. Since the compound NU-9 was shown to improve similar cellular problems in CSMN that are diseased due to misfolded SOD1 toxicity and TDP-43 pathology, we further investigated its effect on the well-established pathological features of HSP that are recapitulated in the SPASTC448Y mice. We find that NU-9 treatment (100\u00a0mg/kg, for 100\u00a0days) significantly prevented degeneration of corticospinal axons, restored the integrity of mitochondria and endoplasmic reticulum, and reduced the presence of electron-dense accumulations in the CSMN of SPASTC448Y mice.\n\nID: 42313275\nTitle: Immune response in honey bees (Apis mellifera) following humic substance feeding.\nAbstract: Humic substances (HS) are increasingly investigated as natural additives to support health in humans and animals, yet their effects on honey bees remain insufficiently characterised. This study evaluated the impact of a commercial HS-based product on immunity and oxidative status of Apis mellifera. Newly emerged worker bees were kept under laboratory conditions and fed sugar syrup supplemented with 0.5% HS for seven days, while the control group received unsupplemented syrup. Effects of HS were evaluated by analysing the expression of selected immune-related genes, quantifying antimicrobial peptides (AMPs), measuring the activity of antioxidant enzymes, evaluating lipid peroxidation, and characterising hemocyte populations. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. Similarly, catalase enzymatic activity was significantly decreased in the HS group. No significant changes were detected in gene expression for other AMPs and relative abundance of AMPs, or other antioxidant parameters. HS supplementation significantly increased the proportion of medium granular hemocytes (p\u2009<\u20090.05) at the expense of high granular cells (p\u2009<\u20090.01). In conclusion, the 7-day administration of HS at 0.5% did not adversely affect bee health and modulated selected immune parameters. The biological significance of these immunomodulatory effects requires confirmation through challenge studies and field trials under natural conditions.\n\nID: 42307331\nTitle: A Phase-Resolved Geometric Deep Learning Framework Maps Structural Determinants of Disease-Associated Protein Aggregation and Guides Suppressor Design.\nAbstract: Protein aggregation drives major neurodegenerative diseases, yet most computational predictors collapse assembly into static risk scores and do not resolve the distinct structural determinants of nucleation and elongation. Here, we present SKALE 2.0, a phase-resolved geometric deep learning framework that represents proteins as multimodal structural graphs and learns mutation-induced aggregation phenotypes directly from three-dimensional topology. Across SOD1, TDP-43, MAPT, and PRNP, SKALE 2.0 recovered a conserved latent transition from nucleation to elongation while resolving distinct mutation-specific phase sensitivities. Representative protein language model, AlphaFold-derived feature, and non-phase-aware structural baselines failed to recover both phase-dependent mutation modulation and phase separability, indicating that explicit phase conditioning is essential. The learned geometry showed that nucleation is preferentially coupled to buried hydrophobic perturbations, whereas elongation is shaped by solvent-accessible interfaces that support fibril propagation. This framework explains how pathogenic variants can remain globally folded yet acquire aggregation competence through localized structural rewiring. Recombinant SOD1 experiments validated predicted suppressor, enhancer, and phase-switch mutations, demonstrating that initiation and propagation can be tuned independently. SKALE 2.0 links atomic topology to phase-specific assembly kinetics and enables a constraint-aware design of aggregation suppressors.\n\nID: 42302989\nTitle: Establishment and characterization of Hanwoo cumulus cell line for heat stress studies.\nAbstract: Heat stress (HS) negatively affects cattle reproduction, decreasing livestock productivity. HS response in cattle reproductive cumulus cells remain understudied due to limited cell lines and comprehensive omics data. This study aims to establish immortalized cumulus cells from Hanwoo cattle as a HS model and explores their HS response using molecular markers including transcriptomics and proteomics approaches. Immortalized cumulus cells were established from primary cumulus isolated from fresh Hanwoo cattle follicles by using piggyBac transposon-mediated SV40T expression system. HS condition was optimized using reactive oxygen species (ROS) detection, quantitative reverse-transcription polymerase chain reaction, and Western blotting on oxidative and endoplasmic reticulum stress markers under different HS and recovery periods (4 h, 12 h, and 24 h). Transcriptomic and proteomic data were generated to identify HS-related differentially expressed genes (DEG) and proteins (DEP) utilized for gene ontology (GO) and pathway enrichment analysis. We established the first immortalized cumulus cell line with high specificity (99% CD44[+]) for in vitro HS study. ROS accumulation was observed at 4 h HS, leading to immediate upregulation of HSP70 and BiP proteins, with oxidative stress gene expression (SOD1, CAT, GPX1) peaked at 12 h HS. We identified 754 DEGs (fold change\u2265|2|) and 357 DEPs (fold change\u2265|1.5|) related to HS in the cumulus cell line. Enrichment analysis exhibited upregulation in GO and pathways related to protein unfolding and cellular response to HS, respectively, from both the DEG and DEP list. Downregulated DEG and DEP showed significant enrichment in GO related to the extracellular matrix, potentially affecting cumulus-oocyte complex communication for reproductive function. The cumulus cell line serves as a robust in vitro model for studying HS response in cattle reproductive system. The multi-omics data could help clarify the comprehensive HS response and identify possible molecular targets to mitigate negative HS effects in the future.\n\nID: 42299014\nTitle: Pathogenic Proteins Driving ALS Pathogenesis: Molecular Mechanisms and Translational Therapeutic Perspectives.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive degeneration of motor neurons, with protein aggregation as a central pathological hallmark. Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.\n\nID: 42296226\nTitle: Innate immune signaling as a potential pathomechanistic biomarker for distinct subtypes in amyotrophic lateral sclerosis.\nAbstract: Stimulation of the innate immune system has been implicated in ALS and particularly in distinct monogenic forms of ALS. To address whether this is of diagnostic value, we performed a proof-of concept study using qPCR to assess the Interferon score in blood samples of genetic ALS. 56.5% of genetic ALS patients showed significant IFN activation, highest in C9orf72HRE patients (77.3%). About half of FUS-ALS (52.2%), but none of SOD1-ALS patients demonstrated pathological IFN scores. The IFN score significantly correlated with the ALSFRS-R slope and inversely with the time to severe event as a survival surrogate in this genetic ALS cohort. IFN\u2009+\u2009patients were more likely to be male, showed more rapid disease progression and higher neurofilament levels. The IFN score might have the potential as a stratification and readout tool for biomarker-guided individualized therapy in ALS.\n\nID: 42268660\nTitle: Oligogenic variants in NEK1 and ATXN2 in amyotrophic lateral sclerosis: report of two cases and review of the literature.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder that affects the upper and lower motor neurons and leads to progressive paralysis. More than 40 genes have been implicated in familial ALS, which represents about 10% of ALS cases. Some genes, including C9orf72, SOD1, FUS and TARDBP are undoubtedly considered causative, but many others have uncertain pathogenicity and low penetrance. Here, we described the cases of two siblings affected by ALS and carrying both an ATXN2 heterozygous 32 CAG trinucleotide repeat expansion and a novel NEK1 heterozygous c.1674_1677dup. The segregation of both variants in this large family with thirteen siblings may support a role for these variants as susceptibility alleles within an oligogenic model. Our review of the literature suggests that NEK1 variants are frequently found in combination with other variants and repeats expansion in the ATXN2 gene appears to be more associated with monogenic ALS, but also frequently combined with C9orf72 repeat expansion.\n\nID: 42268341\nTitle: Pathogen-mediated priming induces intergenerational immunity against spot blotch in wheat.\nAbstract: Spot blotch, caused by Bipolaris sorokiniana, is one of the most destructive diseases of wheat (Triticum aestivum), particularly in warm and humid regions where yield losses may exceed 30-50%. Heavy dependence on fungicides is neither sustainable nor environmentally safe, creating an urgent need for innovative strategies to enhance crop resilience. Defense priming, a phenomenon in which prior exposure to a mild stimulus enables plants to mount faster and stronger defenses upon subsequent stress offers a promising alternative. Pathogens or pathogen-derived molecules such as PAMPs and effectors are known to serve as effective priming stimuli in plants. In this study, we hypothesized that attenuated spores of B. sorokiniana could act as a priming stimulus to enhance resistance against spot blotch in wheat. By applying a low-dose spore suspension, we sought to establish pathogen-mediated priming as a green vaccination strategy, wherein controlled pre-exposure to attenuated inoculum enhances inducible resistance without imposing detectable growth penalties. Priming significantly reduced disease severity, with primed plants (P\u2009+\u2009B) showing a 2.6-fold lower percent disease index compared to non-primed controls (B). Biochemical analyses revealed enhanced photosynthetic pigments (Chlorophyll a 2.6-fold, Chlorophyll b 3.3-fold, Carotenoids 1.56-fold), increased antioxidant defenses (Superoxide Dismutase 1.4-fold, Catalase 1.4-fold, and Ascorbate peroxidase 1.5-fold, ascorbic acid 2.8-fold, proline 1.6-fold), reduced lipid peroxidation (4.1-fold decrease), and higher phenolic content (1.8-fold) along with elevated PAL (1.9-fold) and POX (1.5-fold) activity. Yield traits also improved, including 1.4-fold higher spike number, 2.0-fold greater spikelet fertility, and a 1.2-fold increase in thousand grain weight (TGW). Strikingly, these benefits were transmitted to the F1 generation, demonstrating that pathogen-mediated defense priming can induce intergenerational immune priming (IGIP). Taken together, our findings establish pathogen-mediated green vaccination as a sustainable strategy to enhance wheat resilience and provide durable protection against spot blotch.\n\nID: 42267104\nTitle: Oxidative stress response of Saccharomyces cerevisiae exposed to different molecular weight of polycyclic aromatic hydrocarbons.\nAbstract: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants that cause adverse health effects. This study investigated the toxic effect of different molecular weight PAHs on eukaryote model organism (Saccharomyces cerevisiae) exploiting oxidative stress biomarkers as endpoint indicators. Yeast cells were treated with environmentally relevant concentrations of phenanthrene (PHE), fluoranthene (FLA), and benzo[ghi]perylene (BghiP) for 24\u202fh. Benzo[a]pyrene (BaP) was used as a positive control. Subsequently, expression of genes related to oxidative stress responses, cytotoxicity via targeted analysis of antioxidant mutants, generation of reactive oxygen species (ROS), superoxide dismutase (SOD) activity, and glutathione (GSH) content were assessed. The results demonstrated that viability of S. cerevisiae was related to the molecular weight of PAHs. Oxidative stress related genes SOD1 and SOD2 were found to be prominently expressed. According to the redox mechanism of action, BghiP and BaP triggered ROS formation and induced an increasing activity of SOD. Furthermore, PAH exposure significantly affected the glutathione levels. In summary, PAHs clearly caused oxidative stress. Among PAH samples, the more benzene ring contained more toxicity level exerted in yeast cells.\n\nID: 42250707\nTitle: Inhibitory effect of silymarin on amyloid formation in ALS-associated hSOD1 P66R mutant.\nAbstract: The aberrant aggregation of human superoxide dismutase 1 (hSOD1) into \u03b2-sheet-rich amyloid fibrils is a crucial process in the pathogenesis of amyotrophic lateral sclerosis (ALS), enhancing motor neuron degeneration and disease progression. The P66R mutation in SOD1 destabilizes local structure and promotes \u03b2-sheet-driven fibrillation, which makes it a suitable model for exploring approaches for reducing pathogenic aggregation. Here, we evaluate silymarin, a polyphenolic compound with known antioxidant and neuroprotective properties, for its potential to inhibit P66R-hSOD1 aggregation. ThT fluorescence and transmission electron microscopy analyses demonstrate a significant decrease in amyloid fibril formation in the presence of silymarin; in addition, FTIR spectroscopy confirms the suppression of \u03b2-sheet formation. Fluorescence quenching and ANS binding assays indicate a moderate-affinity binding between silymarin and the mutant protein, along with a reduction in surface hydrophobicity. Hemolysis assays confirm its protective effect against membrane damage induced by aggregates, while molecular docking and dynamic simulations indicate that silymarin stabilizes aggregation-prone areas with hydrogen bonding and hydrophobic interactions, thereby promoting compact conformations and reducing solvent-exposed surfaces. The findings identified silymarin as an effective anti-amyloidogenic agent that reduces \u03b2-sheet accumulation and fibril formation while also decreasing cytotoxicity, highlighting its potential as a therapeutic candidate for ALS.\n\nID: 42240799\nTitle: Synaptic Plasticity Changes in the Somatosensory Cortex During Amyotrophic Lateral Sclerosis Progression and After Swim Training in SOD1-G93A Mice.\nAbstract: Somatosensory cortex hyperexcitability is present in the pre-symptomatic stage of amyotrophic lateral sclerosis (ALS) as evidenced by brain recordings, but its synaptic basis remains unclear. We examined synaptic plasticity, the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses, dendritic spine morphology, and the putative excitatory/inhibitory (E/I) ratio in the B2 barrel of the somatosensory cortex in female mice of an ALS mouse model. Transgenic mice, B6SJL-Tg (SOD1*G93A)1Gur/J, were used as the ALS model, and wild-type (WT) B6SJL/F1 mice served as controls. ALS mice were allocated to experimental groups based on disease stage (pre-symptomatic, onset, or terminal) and training condition (swim-trained or untrained). Swim training was applied after the first onset of symptoms (clinical score 1). We analyzed and quantified the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses and E/I ratios using serial electron micrographs to understand how these parameters change during disease progression and whether swim training influences this process. Our results showed stage-dependent alterations in asymmetric (putative excitatory) and symmetric (putative inhibitory) synaptic architecture in ALS. The obtained data showed an increase in the excitatory synaptic density in the presymptomatic ALS mice. This finding is consistent with previous reports of early cortical hyperexcitability and may reflect structural alterations associated with an initial increase in excitatory synapses before disease onset. Importantly, we report here an increase in inhibitory synapses at disease onset. TEM-based synaptic density quantification revealed reduced excitatory synapse density in the B2 barrel of the somatosensory cortex of trained ALS mice compared to WT controls, alongside a trend toward a reduced putative excitatory/inhibitory synaptic ratio. However, as no significant differences were detected between trained and untrained ALS mice, the contribution of swim training to these alterations remains unclear. Notably, swim training was not associated with detectable adverse effects on somatosensory cortex ultrastructure, excitatory synapse density, or the putative excitatory/inhibitory ratio, supporting previous observations that swim training is well tolerated under these experimental conditions. To our knowledge, these results provide the first TEM-based ultrastructural characterization of synaptic architecture in swim-trained SOD1-G93A mice, although further studies are needed to establish the underlying mechanisms and therapeutic relevance in ALS.\n\nID: 42239390\nTitle: A Liver-Targeted Copper Supplement Reduces Metabolic Dysfunction-Associated Liver Steatosis by Increasing Lipolysis and Fatty Acid Oxidation.\nAbstract: Metabolic-associated steatotic liver disease (MASLD) is a prevalent liver disease driven by complex dysregulation of hepatic lipid metabolism. Here we show that copper deficiency is a nutrient vulnerability in steatotic liver disease and that selective liver-targeted copper supplementation can reduce excess lipid accumulation. Analysis of steatotic patient and mouse tissues identify widespread alterations in hepatic copper homeostasis markers. Integrated multi-omics analyses reveal that copper induces lipolysis of PLIN2-containing lipid droplets while lipid importer CD36 is downregulated. We show that copper inhibits cAMP hydrolase activity of PDE3B, thus activating PKA-mediated HSL and AMPK activation upstream of lipolysis. Fatty acids liberated through lipolysis are subsequently degraded via enhanced mitochondrial fatty acid oxidation, supported by energetic rewiring toward oxidative phosphorylation (OXPHOS) with increased copper-dependent complex IV and SOD1 activity. Our findings establish a multi-pronged mechanism by which hepatic copper supplementation coordinately regulates lipid metabolism in response to steatosis and unveils a therapeutic metallomedicine strategy to rewire lipid regulation. Liver-targeted copper supplementation reduces diet-induced liver steatosis by dual activation of lipolysis and fatty acid degradation pathways.\n\nID: 42212756\nTitle: 5-Hydroxytryptamine Distribution Alteration in Both Neuron and Synapse of Tg(SOD1*G93A)1gur Mice: A Potential Intervention Candidate Strategy for Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease; the precise pathogenesis of sporadic ALS (sALS) has not yet been elucidated up to now. Previous studies revealed that the abnormal alterations of some non-motor neurons (non-MN) were a potential pathogenesis of sALS. Therefore, this study aims to search the potential evidences of non-MN in the pathogenesis of ALS via exploring potential relationships between 5-hydroxytryptamine (5-HT) neurons and the development of ALS. We employed fluorescent immunohistochemistry to investigate the altered distribution patterns of 5-HT and tryptophan hydroxylase 2 in the spinal cord and brainstem of Tg(SOD1*G93A)1Gur (TG) and wild-type (WT) mice. Additionally, we used western blot to analyze the expression levels of 5-hydroxytryptamine receptor 1A (5-HTR1A) and 5-HTR2A. Our findings revealed that 5-HT synapses were primarily distributed in the funiculus lateralis, anterior horn, posterior horn, central lateral column, and the area around the central canal of cervical, thoracic, and lumbar segments, and raphe nucleus as well as lateral paragigantocellular nucleus, and gradually reduced following age increase in WT mice. However, 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem gradually increased following the progression of disease and presented a significantly negative correlation between the increased distribution of 5-HT synapses and neurons and the reduction of neural cell number (positively correlated with the increase in neural cell death) at the onset and/or progression stage of TG mice. 5-HTR1A significantly increased, while 5-HTR2A significantly decreased at the onset stage of TG mice. Our study speculated that the distribution changes of 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem play a potential protective role in the pathogenesis of sALS through a compensatory 5-HT increase.\n\nID: 42196191\nTitle: Longitudinal CSF and Serum Biomarker Dynamics in Tofersen-Treated SOD1-ALS: A Real-World Multicentre Cohort Study.\nAbstract: Tofersen is a gene-targeted therapy for superoxide dismutase 1 (SOD1)-associated amyotrophic lateral sclerosis (ALS), but neurofilament light chain (NfL) may not fully capture the biological response to treatment. We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression. These findings suggest that longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.\n\nID: 42195033\nTitle: From Mutation to Manifestation: Penetrance in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by progressive loss of motor neurons in the brain and spinal cord. While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS.\n\nID: 42480751\nTitle: Catalytic Scavenging of ROS: A Mechanistic Review of CeO2 NPs and Fe3O4 NPs as Prototypical Antioxidant Nanozymes.\nAbstract: The rising global burden of diseases linked to reactive oxygen and nitrogen species (ROS/RNS) - including inflammatory disorders, cancers, neurodegenerative conditions, and cardiovascular disease - has intensified interest in enzyme-mimicking nanomaterials (nanozymes) as tools to modulate cellular redox balance. Natural antioxidant enzymes, chiefly superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), are the principal enzymatic defenses against oxidative stress, but their clinical use is limited by poor stability, short half-life, and high cost. Nanozymes, producible at scale with tunable, stable activity, offer a promising alternative. This review is organized around a mechanistic distinction essential to the literature but frequently blurred: antioxidant nanozymes, which net-scavenge ROS through reversible redox cycling, versus pro-oxidant nanozymes, which net-generate ROS through Fenton-type chemistry. Cerium oxide nanoparticles (CeO2 NPs) are examined as the prototypical antioxidant nanozyme, their SOD- and CAT-like activities arising from reversible Ce3+/Ce4+ cycling and oxygen-vacancy chemistry at the surface, with the Ce3+/Ce4+ ratio determining which activity predominates. Magnetite nanoparticles (Fe3O4 NPs) are examined as the prototypical pro-oxidant nanozyme, dominated by peroxidase-like Fenton chemistry driven by surface Fe2+/Fe3+ cycling that generates hydroxyl radicals, exploited for antibacterial and antitumour applications, with CAT-/SOD-like activity arising only as a secondary, concentration- and pH-dependent behaviour. Beyond mechanism, this review surveys the expanding application space for both classes, including ROS/analyte sensing, antibacterial therapy against resistant pathogens, diabetic wound healing, treatment of ROS-associated disease, and catalysis by related metal-oxide nanocatalysts. By keeping the two tracks mechanistically distinct, this review provides a clearer framework for rational nanozyme-based therapeutic design.\n\nID: 42458512\nTitle: Targeting astrocyte-mediated neurotoxicity induced by ALS/FTD-associated RNA binding proteins.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative disorders characterized by reactive astrocytes that contribute to neuronal injury through TAR DNA-binding protein 43 (TDP-43)-or fused in sarcoma (FUS)-driven neuroinflammatory signaling. Dehydrocostus lactone (DHE), a blood-brain barrier-permeable sesquiterpene lactone with established anti-inflammatory activity, represents a promising but unexplored therapeutic candidate for ALS/FTD. The therapeutic effects of DHE were evaluated in primary mouse and human astrocytes expressing ALS/FTD-associated RNA-binding protein pathology, ALS patient-derived fibroblasts, and primary cortical neurons exposed to astrocyte-conditioned medium. Drosophila models expressing mutant FUS or TDP-43 in glial cells were used to assess locomotor performance and survival. Molecular analyses examined nuclear factor kappa B (NF-\u03baB) signaling, nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant responses, protein aggregation, mitochondrial function, and inflammatory mediator production. Plasma concentrations of inflammatory cytokines and chemokines were measured in patients with sporadic ALS. DHE exerted neuroprotective effects through a dual mechanism involving suppression of NF-\u03baB-dependent inflammatory signaling and activation of NRF2-mediated antioxidant pathways in astrocytes exhibiting FUS or TDP-43 proteinopathy. DHE attenuated astrocyte-mediated neurotoxicity and improved neuronal mitochondrial function in conditioned-medium assays. In addition, DHE reduced pathological FUS accumulation in FUS P525L-expressing astrocytes and in stress-challenged patient-derived fibroblasts. In Drosophila models, DHE significantly improved locomotor function and extended survival. Translationally, the chemokines CXCL10, CCL3, and CCL19 were elevated in plasma from patients with ALS, were induced by FUS or TDP-43 pathology in astrocytes, and were suppressed by DHE treatment, supporting the clinical relevance of the inflammatory pathways targeted by DHE. DHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms. The consistent therapeutic effects observed across mouse and human cellular models, patient-derived samples, and in vivo Drosophila models support further investigation of DHE as a potential therapeutic strategy for ALS/FTD and highlight astrocyte-mediated signaling pathways as actionable targets in neurodegenerative disease.\n\nID: 42453524\nTitle: Therapeutic potential of adipose-derived stem cell transplantation in amyotrophic lateral sclerosis: A combined clinical case and preclinical study.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an inevitably fatal neurodegenerative disease with no adequate treatment. Transplantation of adipose-derived stem cells (ADSCs) may be an effective therapeutic strategy for delaying progression or restoring neurological function in ALS. We evaluated the safety and therapeutic efficacy of intravenous (i.v.) and intracerebral (i.c.) ADSC injection in a late-stage ALS patient and in a SOD1 transgenic (Tg) mouse model. Magnetic resonance imaging (MRI) and computed tomography (CT) were conducted to examine potential cerebral hemorrhage and tumor generation in the treated patient. In addition, maximal inspiratory pressure, maximal expiratory pressure, tidal volume, and respiratory rate were measured as indices of respiratory function. ADSC transplantation was safe, with MRI and CT showing no hemorrhage or tumorigenesis up to 12 months. The patient's Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score improved from 7 to 9 at 3 months and remained above baseline for 6 months. Respiratory function was preserved during this period. In SOD1 Tg mice, i.c. and i.v. ADSC infusion significantly prolonged survival (165.0 \u00b1 10.4 and 147.3 \u00b1 4.5 days vs. 129.7 \u00b1 3.9 days) and improved motor scores (P < 0.01). This preliminary finding suggests potential therapeutic feasibility, but further studies with larger cohorts are needed to confirm its safety and efficacy.\n\nID: 42451760\nTitle: Study on Persulfate Activation and Tetracycline Degradation by Chlorine-Doped Carbon Derived from ZIF-8.\nAbstract: To address the inherent drawbacks of peroxymonosulfate advanced oxidation processes (PMS-AOPs), including the low efficiency of reactive species production, short radical half-lives, and restricted pollutant degradation performance, sodium salt-assisted modification was adopted to fabricate ZIF-8-derived carbon. In this study, sodium salt-assisted modification was adopted to treat ZIF-8, and the chlorine-doped derived carbon materials HNC-Tx-Cl were prepared for peroxymonosulfate activation and tetracycline degradation in water. Compared with NC-800 fabricated by direct calcination of ZIF-8 at 800 \u00b0C, HNC-800-Cl synthesized via NaCl-assisted calcination exhibits more abundant pore structures and richer carbon defects, with a specific surface area of 1115 m2/g and a high graphitic defect ratio ID/IG of 1.20. Catalytic tests reveal that HNC-800-Cl achieves 93.39% tetracycline removal within 90 min at a catalyst dosage of 0.05 g L-1 and PMS concentration of 0.1 mM. The system possesses a strong anti-interference ability toward complex water environments, maintaining a favorable degradation performance in the presence of coexisting anions, natural organic matter and actual water matrices. It also exhibits outstanding cycling stability, retaining a removal rate of 80.34% after five recycling runs. Radical quenching experiments and EPR characterization verify that superoxide radical (\u00b7O2-) is the dominant reactive species during tetracycline degradation. Both the radical and non-radical pathways are clarified to illustrate the mechanisms of PMS activation and pollutant degradation. This work provides a novel catalytic material strategy to overcome the deficiencies of conventional PMS-AOPs, and offers a new perspective for structural regulation and non-metallic doping modification of ZIF-8-derived carbon materials.\n\nID: 42441689\nTitle: Age-based risk estimates for C9orf72RE-related diseases: Theoretical developments and added value for genetic counseling.\nAbstract: The C9orf72 hexanucleotide repeat expansion is the most common genetic cause of amyotrophic lateral sclerosis (ALS) or frontotemporal dementia (FTD). In genetic counseling, children of mutation carriers are often told that they have a 50% risk of carrying the mutation, but this figure does not take into account the fact that penetrance is age-related, with a unimodal distribution of disease onset around 58 years of age. Using a Bayesian approach, we developed a theory to calculate the probability of carrying the mutation for asymptomatic relatives (children/siblings and grandchildren/niblings) as well as the probability of developing ALS/FDT within a given time frame, based on their age. Using published data on age-related penetrance, we then calculated these probabilities and developed an online simulator that makes it easy to calculate them on a case-by-case basis. The conditional probabilities obtained can be very different from Mendelian values. For example, a 70-year-old asymptomatic child born to a carrier has approximately a 6% risk of being a carrier, which is far from 50%. For grandchildren, taking into account both their age and that of their parents also leads to figures that are much lower than those obtained if only their age were considered. For consultands, the decision to undergo testing is based in part on risk estimates. In this regard, the refined estimates and simulator we propose may prove to be valuable tools for genetic counseling for families affected by ALS/FTD linked to the C9orf72RE mutation. In addition, the formulas used in this study could also be used to calculate risk estimates for other diseases caused by autosomal dominant mutations with age-dependent penetrance.\n\nID: 42435905\nTitle: Boosting O2 activation and substrate adsorption over single-atom Zr-doped Pt/CeO2 for enhanced glucose oxidation to glucaric acid.\nAbstract: CeO2 is widely employed in heterogeneous catalysis due to its excellent oxygen storage and release capacity. However, enhancing oxygen adsorption and activation as well as substrate adsorption capability in aqueous-phase to optimize catalytic oxidation performance remains a significant challenge. Herein, a Pt/Zr-CeO2 catalyst was prepared via a single-atom doping strategy. Characterization revealed that Zr atoms were successfully incorporated into the CeO2 lattice, markedly increasing the oxygen vacancy concentration and enhancing the surface Lewis acidity. This dual modulation not only creates abundant sites for molecular oxygen activation but also facilitates efficient adsorption of aldehyde and hydroxyl groups of glucose. Mechanistic studies indicate that the enhanced oxygen vacancies promote the generation of superoxide radicals (O2-). These radicals are further converted into peroxide species (O22-) under aqueous conditions and induce the formation of hydroxyl radicals (OH), which synergistically activate CH and OH bonds of glucose. The synergy between oxygen vacancies and Lewis acid sites enables the highly selective production of glucaric acid under mild conditions. Meanwhile, the catalyst exhibits excellent stability during cycling tests, with no obvious deactivation. This study demonstrates that single-atom Zr doping is an effective strategy for modulating the defect chemistry and surface acidity of CeO2-based catalysts, providing new insights into the design of high-performance oxidation catalysts for biomass valorization.\n\nID: 42427672\nTitle: Small molecules targeting ARF1 interaction with C9orf72:SMCR8:WDR41 complexes suppress its overactivation implicated in ALS/FTD.\nAbstract: The hexanucleotide repeat expansion in C9orf72 gene is the most common genetic cause of amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD). The C9orf72 protein forms a complex with SMCR8 and WDR41 (CSW), which functions as a GTPase-activating protein (GAP) regulating ARF1 and RAB small GTPases. While these findings implicated ARF1-GAP dysregulation in ALS/FTD and supported ARF1 suppression as potential intervention, small molecules that modulate ARF1-CSW interactions are lacking. In this study, we demonstrated upregulation of tyrosine-phosphorylated (Tyr-782) ASAP1 (also known as AMAP1, DDEF1, or Centaurin \u03b24), an ARF-GAP, in human motor cortex of both sporadic ALS and ALS with C9orf72 mutations. Ectopic C9orf72 expression partially mimicked the effects of a known ARF1 inhibitor brefeldin A to disperse Golgi apparatus. Computer-aided rational drug design with high-throughput in-silico screening identified MCULE-5095997944 (Named as SCC944) as a ARF1-CSW modulator. SCC944 binds directly to ARF1 and reduced GTP-bound ARF1 levels upon ARF1 activation. SCC944 demonstrated brefeldin A-like ARF1-dependent alteration of organelle organization including Golgi, microtubules, and mitochondria, but also a protein trafficking pattern that is distinct from brefeldin A mechanism. These studies identified the first small molecule targeting ARF1-CSW interaction and further support ARF1 modulation as a potential therapeutic approach for ALS/FTD.\n\nID: 42423311\nTitle: Switching Photocatalytic NH3 Oxidation Pathways from NOx to N2 via Synergistic Kineto-Thermodynamic Modulation on TiO2.\nAbstract: The escalating demand for ammonia (NH3) as a promising energy vector and essential chemical raw material in both industrial and agricultural applications, coupled with its noxious and caustic properties, has led to significant atmospheric emissions that pose environmental and health risks. Photocatalytic NH3 oxidation over TiO2 is a promising strategy for air purification but is hindered by poor selectivity, often leading to the formation of toxic NOx byproducts due to the complex reaction network involving multiple competing pathways and intermediates. This study addresses this selectivity issue by designing a modified TiO2 photocatalyst through a synergistic defect-dopant engineering approach. Through controlled doping and defect engineering, we demonstrate that N doping and OVs distinctly modulate the reaction mechanism and products' selectivity. Nitrogen doping thermodynamically promotes N2 formation by stabilizing NH2 intermediates and facilitating their selective coupling with NO, whereas OVs kinetically facilitate NH3 and O2 dissociation, promoting superoxide-mediated oxidation, leading to overoxidized products such as NOx and nitrate/nitrite HNOx- species. An optimal N-doped TiO2 catalyst achieves 87% NH3 conversion with 80% N2 selectivity and minimal NOx emission (\u223c5 ppm), while exhibiting excellent stability over multiple cycles. This work elucidates a defect-dopant strategy that optimizes kinetic and thermodynamic aspects of NH3 oxidation, providing a design principle for selective photocatalytic nitrogen management toward sustainable air purification.\n\nID: 42421523\nTitle: Membrane-Confined Proton Management Orchestrates Proton-Electron Transfer for Efficient Photocatalytic Hydrogen Peroxide Synthesis.\nAbstract: Coordinating proton and electron transport remains a central challenge in photocatalysis, particularly for H2O2 synthesis, where two-electron oxygen reduction requires synchronized proton delivery and charge transfer. Here, we report hydroxyl-functionalized three-dimensional covalent organic framework (COF) membranes that regulate proton-coupled electron transfer within ordered nanochannels. Phenolic hydroxyl groups are precisely embedded in the membrane pores as internal proton reservoirs, while the continuous COF framework provides pathways for photogenerated electron transport. By tuning hydroxyl density, the dihydroxylated COF-2OH membrane establishes an optimal proton-management microenvironment, promoting O2 adsorption, charge separation, superoxide/*OOH intermediate formation, and dynamic proton recycling. Under one-sun irradiation in pure water and ambient air, COF-2OH achieves an H2O2 production rate of 21.79\u00a0mmol g- 1 h- 1 without sacrificial agents or cocatalysts, greatly outperforming the corresponding powder catalyst. Mechanistic experiments and simulations reveal that membrane confinement and hydroxyl-mediated proton buffering jointly synchronize proton and electron fluxes during continuous photocatalysis. The free-standing membrane can also be integrated into a tubular Al2O3-supported reactor for in situ H2O2-driven photo-Fenton degradation of organic pollutants. This work establishes proton-managing COF membranes as programmable reaction interfaces for efficient solar H2O2 production and integrated water treatment.\n\nID: 42410741\nTitle: In Vitro Skin-Protective Effects of Sumyong Nature, a Kimchi- and Soybean-Derived Fusion-Fermented Microbial Supernatant, in Human Keratinocytes: Involvement of MAPK-Related Signaling.\nAbstract: Sumyong Nature (SN) is a kimchi- and soybean-derived fusion-fermented microbial supernatant prepared from Lactobacillus acidophilus, Saccharomyces cerevisiae, Weissella cibaria, and Bifidobacterium longum. This study examined the in vitro effects of SN on UVB-induced damage and skin-related cellular responses in human keratinocytes. Cell viability assays, gene expression analysis, luciferase reporter assays, immunoblotting, scratch wound-healing assays, and LC-Q-TOF-MS analysis were conducted. SN showed no significant cytotoxicity in HaCaT or HEK293T cells at concentrations up to 75 \u03bcg/mL. In UVB-irradiated HaCaT cells, SN improved cell viability, suppressed MMP-1 expression, increased HAS-1 expression, and modulated UVB-responsive stress-related markers, including SOD-1, Nrf2, and HO-1. SN also promoted wound closure in keratinocytes and was associated with changes in NF-\u03baB-, AP-1-, CREB-, and MAPK-related signaling responses under the tested conditions. LC-Q-TOF-MS analysis tentatively identified several candidate constituents, including pectolinarin and aloeresin-related compounds. Collectively, these findings suggest that SN exerts multiple beneficial in vitro effects in keratinocyte-based assays, warranting further mechanistic investigation and validation in advanced experimental models.\n\nID: 42410102\nTitle: A changed landscape: five-year retrospective on the paradigm shift in genetic testing practices for ALS in Canada.\nAbstract: Offering genetic testing is increasingly recommended for all individuals with amyotrophic lateral sclerosis (ALS), particularly following the development of gene-targeted therapies, such as tofersen for SOD1-ALS. Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards.\n\nID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.\n\nID: 42401460\nTitle: Cu-MOF-confined Co nanoparticle nanozymes with synergistic peroxidase-like activity for highly selective colorimetric detection of hydroquinone.\nAbstract: Hydroquinone (HQ), a widely used industrial chemical, persists in the environment and poses significant health risks, including carcinogenicity, as classified by the WHO. Existing detection methods (e.g., HPLC, GC-MS) rely on sophisticated instruments and complex procedures, limiting their practicality. Colorimetric sensors based on nanozymes offer simplicity and rapidity but often suffer from poor selectivity because of interference from structural isomers (catechol and resorcinol). The development of a high-performance nanozyme with synergistic activity and selective HQ detection remains a critical challenge. A bimetallic nanozyme (Cu-MOF@CoNPs) was engineered via a \"ship-in-a-bottle\" strategy, which successfully confined cobalt nanoparticles (Co NPs) within a porous copper-organic framework (Cu-MOF) scaffold. Characterization (SEM, XRD, FTIR, and XPS) confirmed the successful integration of Co NPs into the Cu-MOF matrix, preserving structural integrity through a pillaring effect while enhancing active site exposure. The composite exhibited superior peroxidase-like activity, with Michaelis constants (Km) of 0.39\u202fmM (TMB) and 0.18 mM\u202f(H2O2), indicating higher substrate affinity than that of natural horseradish peroxidase (HRP). Catalysis was driven by synergistic Cu-Co electron transfer, generating holes (h+) and superoxide radicals (\u2022O2-). A \"signal-off\" colorimetric sensor was constructed on the basis of the HQinduced reduction of oxidized TMB (oxTMB), achieving a linear range of 0.2-12\u202f\u03bcM, a low detection limit of 65\u202fnM, and high selectivity for HQ over structural isomers (catechol and resorcinol) due to steric confinement and favorable redox kinetics, as verified through expanded interference studies. Practical applicability was validated in tap water, lake water, soil extracts, and cosmetic samples, with recoveries of 94-110% and relative standard deviations <3.5%. The Cu-MOF@CoNPs nanozyme-based sensor provides a cost-effective, portable platform for onsite HQ detection in environmental and consumer safety monitoring. Its high sensitivity, selectivity, and stability highlight the potential of hierarchical MOF-confined bimetallic nanozymes as robust tools for reliable phenolic pollutant analysis.\n\nID: 42400371\nTitle: Reduced penetrance in genetic ALS/FTD spectrum disorders: implications for genetic counseling, predictive testing and treatment.\nAbstract: As the offer of genetic testing for people with ALS/FTD becomes standard of care, clinicians and affected individuals should have accurate and balanced information regarding the clinical and familial implications of test results, including the penetrance of identified variants. Published estimates of the penetrance of specific ALS/FTD variants, including the C9orf72 repeat expansion, have varied widely. However, it is now apparent that most pathogenic variants identified in clinical testing exhibit reduced penetrance. Although data on the disease risk of many variants is limited and likely to evolve in the coming years, the challenges of estimating penetrance should not preclude transparent discussion of these issues with affected individuals and their families. Here, we review published penetrance data and highlight genetic counseling\u00a0considerations to support the clinician in discussing disease risk and facilitating decision-making in genetic testing and patient care.\n\nID: 42399568\nTitle: Photo-responsive Ce-hemin nanozyme-based portable colorimetric sensor for tetracyclines assay.\nAbstract: A cerium ion-modified hemin polymer (Ce-hemin) was synthesized via a facile route, exhibiting photo-responsive oxidase-like activity and excellent stability. The Ce doping effectively prevented hemin aggregation, facilitated electron transfer, enhanced photocatalytic activity, and created a high adsorption capacity for tetracyclines (TCs). Taking advantage of the photo-sensitivity of TCs, a \"turn-on\" colorimetric sensing platform based on Ce-hemin nanozymes and smartphone-readout was constructed for visual analysis of TCs. This sensor offers a wide detection range and a low limit of detection (0.11\u00a0\u03bcM). The mechanism of the \"turn-on\" colorimetric performance was systematically discussed, which involves the abundant generation of superoxide radical anion (\u00b7O2-) species through photoexcitation of the surface complex between TCs and Ce-hemin. Furthermore, machine learning was employed for the accurate classification and identification of two representative TCs and chloramphenicol. Thus, this work provides an environmentally friendly strategy for the detection of TCs without H2O2, and also broadens the application of photo-responsive nanozymes in colorimetric sensors.\n\nID: 42375957\nTitle: Application of nano-selenium as a dietary supplement and its effects on antioxidant status and gene expression related to oxidative stress in broiler chickens.\nAbstract: Antioxidants are important factors in reducing stress in poultry birds. Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers.\n\nID: 42364425\nTitle: Effects of SGLT2 inhibitor dapagliflozin on the heart of rats with long-standing Type 1 diabetes mellitus: Protein profile.\nAbstract: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have beneficial outcomes on the renal and cardiovascular system in diabetes mellitus (DM) patients. As most clinical trials were performed in Type 2 DM, the effects of SGLT2 inhibition in Type 1 DM are not completely clarified. To evaluate the effects of long-standing SGLT2 inhibitor dapagliflozin on the protein profile in rats with a Type 1 DM model. Male Wistar rats were divided into Control (C), DM, and DM treated with dapagliflozin (DM+DAPA) for 30 weeks. DM was induced by a single injection of streptozotocin (40\u202fmg/kg); dapagliflozin was added to chow (5\u202fmg/kg/day). Label-free mass spectrometry was used to assess left ventricular proteome. The bioinformatic tools used were STRING, Cytoscape, Cluster Marker, and ClueGO. ANOVA and Tukey or Kruskal-Wallis and Dunn. Dapagliflozin attenuated body weight loss (C 574\u202f\u00b1\u202f43; DM 339\u202f\u00b1\u202f31*; DM+DAPA 413\u202f\u00b1\u202f30*# g; p\u202f<\u202f0.05 * vs C; # vs DM) and reduced glycemia [C 108 (101-111); DM 554 (529-562)*; DM\u202f+\u202fDAPA 343 (237-416)*# mg/dL; p\u202f<\u202f0.05 * vs C; # vs DM]. Most proteins identified in the networks downregulated in DM vs C were upregulated in DM\u202f+\u202fDAPA vs DM. Proteins related to energy metabolism (CKm, Ak1, Atp5pf, Mdh1, Idh2), excitation-contraction coupling (Actc1, Casq2, Serca1, Serca2a), and oxidative stress (Sod1, Sod2) were upregulated in DM\u202f+\u202fDAPA. KEGG pathways enriched in DM vs Control included gap junction, necroptosis, and fatty acid degradation (upregulated), and Alzheimer's disease, cardiac contraction, and glycolysis/gluconeogenesis (downregulated). In DM\u202f+\u202fDAPA vs DM, upregulated pathways included Parkinson's disease, cardiac contraction, citrate cycle, necroptosis, and cyclic guanosine monophosphate-dependent protein kinase (PKG) signaling pathway; downregulated proteins were linked to ketone body metabolism. Dapagliflozin modulates cardiac protein abundance by attenuating DM-induced changes in Type 1 DM rats.\n\nID: 42362003\nTitle: Astragalus polysaccharides alleviate oxidative damage by activating the Keap1-Nrf2 antioxidant pathway through miR-183-5p in a fish cell model.\nAbstract: Astragalus polysaccharides (APS), one of the star antioxidants among traditional Chinese medicine, have widespread applications in healthcare, veterinary, and fishery fields. However, the mechanisms underlying their antioxidative action remain largely unknown. In this study, the protective role of APS in H2O2-induced oxidative damage and associated mechanism were investigated in large yellow croaker head kidney (LYCK) cells. We found that the APS significantly inhibited H2O2-induced cytotoxicity, ROS accumulation, and mitochondrial damage, thereby alleviating subsequent apoptosis and pyroptosis. Further studies showed that APS activated the Keap1-Nrf2 antioxidant signaling pathway, thus up-regulating the downstream antioxidant genes (SOD-1, CAT, HO-1, and GR), enhancing SOD-1 and CAT activities and T-AOC level, and decreasing MDA content. Mechanistically, APS activate this antioxidant signaling pathway by inducing the expression of microRNA-183 (miR-183-5p). The produced miR-183-5p binds to the 3'UTR of Keap1 mRNA and promotes its degradation, leading to consequent Nrf2 activation. Our results therefore unveil the mechanism by which APS alleviate oxidative damage in a fish cell model, and provide the theoretical basis for their application in aquaculture.\n\nID: 42356470\nTitle: Adenosine A2A Receptors Mediate Resveratrol-Induced Nrf2 Activation and Cytoprotection Against Oxidative Stress in HeLa Cells.\nAbstract: Background/Objectives: Oxidative stress is a major contributor to cellular injury in many pathological conditions, including neurodegenerative disorders. Resveratrol, a natural polyphenol with antioxidant properties, has been proposed as a cytoprotective compound, although the molecular mechanisms underlying its effects remain incompletely understood. Here, we investigated whether the protective action of resveratrol against hydrogen peroxide-induced oxidative stress is mediated by adenosine receptor signalling and activation of the Nrf2 pathway in HeLa cells. Methods: Cells were treated with resveratrol alone or in combination with selective adenosine receptor antagonists and oxidant challenge, and cell viability, ROS production, receptor involvement, and Nrf2 expression and localization were analyzed. Results: Resveratrol at a non-toxic concentration significantly protected HeLa cells against oxidative damage, reduced ROS accumulation, promoted Nrf2 nuclear translocation and gene expression, and enhanced the gene expression of antioxidant enzymes such as SOD1, catalase, HO-1, and NQO1. Pharmacological blockade of the A2A receptor prevented this protective effect, whereas the inhibition of A1 and A3 receptors enhanced it and avoided the increased SOD1, catalase, HO-1, and NQO1 gene expression promoted by resveratrol alone. Moreover, A2A antagonism was associated with reduced PKA levels, consistent with the involvement of the cAMP/PKA signalling axis. Conclusions: Taken together, these observations support a model in which adenosine A2A receptor signalling contributes to resveratrol-associated cytoprotection and Nrf2 activation in a human non-neuronal cell model. Our findings therefore provide mechanistic insight into resveratrol-adenosine receptor interactions and generate hypotheses to be tested in disease-relevant neuronal systems.\n\nID: 42353210\nTitle: Selective Alterations of Thiol Redox Homeostasis and Antioxidant Enzyme Activity in Advanced Atherosclerosis.\nAbstract: Atherosclerosis is a progressive vascular disease characterized by lipid-rich plaque accumulation, oxidative stress, and chronic inflammation, contributing to coronary heart disease, stroke, and peripheral arterial disease. This study investigated the impact of inflammation, vascular calcification, and statin therapy on redox balance in blood and carotid artery plaques, aiming to identify potential biomarkers for disease assessment. Thirty-two patients undergoing carotid endarterectomy provided 34 plaque samples. Enzyme activities in plaque/erythrocytes and -SH group concentration in plasma/plaque were measured. Pathological analysis was performed to determine inflammation/calcification grade, the presence of mast cells and plaque composition. The results showed that mast cells were associated with reduced non-protein -SH groups, indicating selective thiol consumption and serving as a qualitative marker of oxidative burden. Reduced catalase activity in erythrocytes was associated with advanced calcification, pointing to long-standing systemic oxidative stress. Statin therapy enhanced systemic superoxide-dismutase 1 activity, increased -SH groups, and modulated plaque-specific glutathione reductase activity, attenuating sex-related differences in redox regulation. These findings highlight the complex interplay between systemic and local oxidative processes in atherosclerosis through alterations in redox-related biomarkers such as plasma -SH group concentrations and catalase activity.\n\nID: 42353187\nTitle: Overexpression of Stanniocalcin 2 Protects Differentiated QM7 Cells from H2O2-Induced Oxidative Damage.\nAbstract: Oxidative stress, caused by excessive reactive oxygen species (ROS) accumulation, is a major factor in muscle cell damage and muscle atrophy-related disorders. Although Stanniocalcin 2 (STC2) is involved in cellular stress and exhibits cytoprotective effects in various cell types, its role in skeletal muscle cells during oxidative stress is unclear. This study investigated the effects of STC2 overexpression in quail muscle (QM7) cells exposed to H2O2-induced oxidative stress. STC2 expression was upregulated in non-transfected QM7 cells following H2O2 treatment. Stable STC2-overexpressing cells were differentiated for 4 days, and then assessed for cell viability, ROS accumulation, cell death, and myotube morphology following H2O2 treatment. Compared with control cells, STC2-overexpressing cells exhibited higher cell viability, reduced ROS accumulation, and decreased cell death. STC2 overexpression also attenuated the H2O2-induced reduction in MyHC protein expression. Antioxidant-related genes, including Superoxide Dismutase 1, Glutathione Peroxidase 1, Heme Oxygenase 1, and NAD(P)H Quinone Dehydrogenase 1, were significantly upregulated in STC2-overexpressing cells. Compared with the control cells, nuclear factor erythroid 2-related factor 2 protein levels were not increased in STC2-overexpressing cells under oxidative stress conditions. These findings suggest that STC2 overexpression alleviates oxidative stress-induced cellular damage and may contribute to protective antioxidant responses in muscle cells.\n\nID: 42352067\nTitle: Urate as a CO3\u2022- Scavenger and Regulator of SOD-1 and OGG1 Enzymes: Insights from DFT, Molecular Docking, and Molecular Dynamics.\nAbstract: The potency of urate, an abundant human plasma antioxidant, in preventing oxidative damage caused by the carbonate radical anion CO3\u2022-, was studied using quantum chemical calculations. The influence of microhydration of CO3\u2022-/CO32- and urate-/urate\u2022 couples on the thermodynamic and kinetics of the one-electron oxidation process was investigated. Depending on the degree of microhydration, the estimated rate constant for one-electron transfer is in the range of 2.0-7.3 \u00d7 109 M-1 s-1, in good agreement with the experimental value of 1.3 \u00d7 109 M-1 s-1. Modeling using vertical detachment energy and electron affinity, the driving forces of single electron transfer revealed urate(H2O)6- and CO3(H2O)9\u2022- clusters as the most likely existing species in water. Molecular docking revealed a favorable interaction of urate with the catalytic pocket of SOD1. Urate binds more strongly to the anionic active center of SOD1 than the reference inhibitor LSC-1, indicating its potency to prevent HCO3--supported CO3\u2022- formation. In contrast, the known OGG1 inhibitor TH13264 shows substantially stronger binding than urate, indicating urate's weaker affinity toward the DNA repair enzyme catalytic pocket. The molecular dynamics data indicate that urate binding does not destabilize either SOD1 or OGG1. In light of increasing evidence that the major source of oxidative stress could be CO3\u2022-, rather than the commonly assumed hydroxyl radical HO\u2022, the obtained results indicate the inherent ability of plasma to combat oxidative stress induced by this selective, milder oxidant. Such an ability with respect to the non-selective, highly reactive HO\u2022 does not exist in vivo.\n\nID: 42351996\nTitle: Metabolic Responses of Melanocytes and Melanoma Cells to UVA Radiation and Phytocannabinoids Exposure.\nAbstract: Ultraviolet A (UVA) radiation disrupts the redox balance of melanocytes and may lead to the development of melanoma, highlighting the need for new skin protection strategies. This study assessed the effect of phytocannabinoids [cannabigerol (CBG), cannabidiol (CBD), and CBG + CBD] on redox homeostasis in control and UVA-exposed melanocytes and in melanoma cells (SK-Mel-5). UVA radiation increased the activity of prooxidant enzymes in both melanocytes and SK-Mel-5 cells and, consequently, the level of reactive oxygen species (ROS) (approx. 2-fold). It also activated nuclear factor erythroid 2 (Nrf2), as reflected by increased expression of heme oxygenase 1 (HO-1) (melanocytes approx. 2-fold; SK-Mel-5 approx. 7-fold). Concomitantly, antioxidant mechanisms were impaired, as demonstrated by reduced superoxide dismutase (SOD1/SOD2) activity and impaired glutathione and thioredoxin function. These changes were accompanied by increased levels of oxidative damage markers (isoprostanes, 4-hydroxynonenal-4-HNE, and 4-HNE-protein adducts) (43-100%) and increased inflammatory signaling, including increased expression of nuclear factor kappa B (NF-\u03baB) subunits (melanocytes: p52 ~2-fold, p65 ~75%; SK-Mel-5: ~4-4.5-fold) and tumor necrosis factor alpha (TNF-\u03b1; ~30%). Phytocannabinoid treatment modulated these UVA-induced changes. In SK-Mel-5 cells, phytocannabinoids normalized the activity of prooxidant enzymes and consequently reduced ROS levels (~30%). They also reduced Nrf2 activation and HO-1 expression; however, CBG increased HO-1 level in melanocytes (~25-40%). Furthermore, phytocannabinoids enhanced antioxidant defense by increasing SOD activity, particularly in melanocytes (~10-40%), and restoring the glutathione and thioredoxin systems. Markers of oxidative damage were reduced by approximately 23-37% after treatment. Furthermore, phytocannabinoids attenuated NF-\u03baB activation (p52 ~18-28%, p65 ~25-29% in melanocytes; ~20% in SK-Mel-5), while TNF-\u03b1 levels remained unchanged. The effects in non-irradiated cells were modest (<15%). These results suggest that phytocannabinoid-mediated modulation of redox balance may stabilize melanocytes exposed to UVA radiation and potentially reduce the risk of neoplastic transformation. However, the observed protective effects in SK-Mel-5 cells require further investigation and detailed molecular analysis.\n\nID: 42351978\nTitle: Loss of NRF2 During Aging Contributes to Myocardial Functional Decline.\nAbstract: Aging is a significant risk factor for cardiovascular diseases. The prevalence of heart failure increases with age, making it a leading cause of morbidity and mortality. We investigated age-associated changes in expression of Nuclear Factor (Erythroid-derived 2)-Like 2 (NFE2L2 or NRF2) in the myocardium of humans, rhesus monkeys, Fischer rats, and C57BL/6 mice. NRF2 is a transcription factor that orchestrates the expression of genes involved in antioxidant and detoxification responses. Analyses of RNA-seq data from the Genotype-Tissue Expression (GTEx) project, which contains left ventricular samples from 294 male donors, revealed a trend of age-associated declines in NRF2 transcripts and several of its downstream genes (SOD1, SOD2, CAT, GCLM, and AKR1B). Age-dependent decreases in NRF2 protein expression were observed in the myocardium of Rhesus monkeys and Fischer rats. To determine whether NRF2 loss contributes to myocardial aging, we evaluated cardiac function of NRF2 knockout mice (KO) at 19 and 24 months of age. At 19 months, the NRF2 KO mice exhibited diastolic dysfunction, characterized by an increased end-diastolic volume (EDV) and end-systolic volume (ESV), accompanied by a reduced ejection fraction (EF) and fractional shortening (FS), indicative of early onset of heart failure. The NRF2 KO mice displayed premature aging phenotypes and had reduced lifespans. Our findings support the trend of NRF2 signaling decline with age, and that loss of NRF2 accelerates the maladaptive cardiac remodeling and functional deterioration associated with aging.\n\nID: 42346121\nTitle: Dexmedetomidine Preserves Hippocampal Neurogenesis During Recovery from Neonatal Hyperoxia in Rats.\nAbstract: Neonatal hyperoxia induces oxidative stress that disrupts neurodevelopmental processes. While dexmedetomidine (DEX) exhibits acute neuroprotective properties, its long-term impact on developmental trajectories during recovery remains incompletely understood. This study examined whether a single neonatal dose of DEX modulates hippocampal neurogenesis following hyperoxia across defined postnatal stages. Six-day-old Wistar rats were exposed to 80% oxygen for 24 h and evaluated at postnatal days (P) 9, 11, and 14 after recovery in room air. Mechanistically, hyperoxia permanently triggered apoptotic cascades, evidenced by sustained transcript upregulation and increased histological apoptosis and cell loss across the cortex and hippocampus, while disrupting the hippocampal progenitor niche, suppressing key differentiation factors (Sox2, Tbr2, Prox1, Calb1) and altering mature NeuN expression. Likewise, markers for autophagy (Atg5/12, Beclin1), neurotrophins (BDNF, NGF, NT3), and plasticity markers (Nrp1, Sem3a) showed reduced expression. Proactive treatment with DEX (5 \u00b5g/kg) significantly reversed these detrimental patterns. First, DEX elicited a robust antioxidant response (Nrf2, SOD1, SOD3 induction). Second, DEX effectively suppressed hyperoxia-induced programmed cell death and tissue degeneration up to P14. Crucially, this dual protection sustained the neurogenic niche, safeguarding autophagy processes as well as neurotrophic and neuronal plasticity mediators, while showing excellent safety under normoxia. In conclusion, a single dose of DEX mitigates acute oxygen injury and exhibits beneficial, stage-specific effects within hippocampal neurogenic niches during the postnatal phase, highlighting its potential to preserve neurodevelopmental trajectories.\n\nID: 42315786\nTitle: Scalable diclofenac lauryl ester prodrug nanoparticles: a promising strategy for reducing inflammation associated with intervertebral disc degeneration.\nAbstract: As the most frequent clinical problem, intervertebral disc degeneration (IVDD) and associated inflammatory pain are still a big challenge, thus there is a need for improved and more lasting therapeutic approaches. In this study, a lipidic prodrug of diclofenac, Diclofenac Lauryl Ester (L-DCF), was synthesized and formulated into nanoparticles (Nanofenac-L) using the ethanol injection method followed by microfluidization. The encapsulation efficiency of Nanofenac-L was >\u200997% with sustained drug release, releasing around 65% of the diclofenac in 48\u00a0h. The therapeutic potential of Nanofenac-L was evaluated in rat intervertebral disc-derived nucleus pulposus cells.\u00a0Nanofenac-L was found to be more effective than free Diclofenac Sodium (DCF-Na) in terms of anti-inflammatory activity, which was confirmed with significant suppression of COX-2 and Substance P. Furthermore, Nanofenac-L increased the expression of antioxidant genes in cells, such as SOD1, GPX1 and PRDX1. Preventive treatment was found to have shown therapeutic value whereas the curative treatment yielded a significant therapeutic effect indicating the possibility of Nanofenac-L to alleviate inflammation as well as to slow down disease progression. Altogether, these results suggest that Nanofenac-L could represent a promising long-lasting anti-inflammatory, pain relieving and antioxidant nanotherapeutic. Comprehensive preclinical and clinical evaluation is essential to translate these findings into viable therapies.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression.

Recent longitudinal studies emphasize that \"longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.\" The mechanistic underpinnings of motor neuron loss in these models are increasingly attributed to the dual role of mutant SOD1, wherein \"mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species.\" Clinical management is shifting toward early detection via non-invasive modalities, as \"Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests.\" Furthermore, the potential for non-SOD1 pathology requires rigorous biomarker assessment, as evidence indicates that \"the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The application of magnesium-silicide based hydrogen gas release serves as an innovative strategy to intercept the crosstalk between oxidative stress and neuroinflammation.\n*   The use of Platelet Factor 4 (PF4) demonstrates a selective neuroprotective benefit in SOD1-driven ALS, bypassing PINK1-dependent mechanisms to restore proteostasis.\n*   The phenomenon of macrophage inclusions (\"tofersenophages\") in CSF has been identified as a persistent, albeit clinically ambiguous, finding during ASO therapy, which surprisingly correlates with favorable clinical outcomes.\n*   Neuromuscular ultrasound serves as a high-sensitivity, non-invasive biomarker that detects disease pathology at stages prior to electroneurographic abnormalities.\n*   Genetic testing for ALS has achieved near-universal integration in clinical practice by 2025, with sponsored, cost-free testing panels significantly increasing diagnostic yields in sporadic cases.\n*   The identification of the JAK2 gene as a novel genome-wide significant signal in the Indian cohort underscores the importance of population-specific genetic surveying.\n*   The integration of phase-resolved geometric deep learning (SKALE 2.0) now allows for the constraint-aware design of aggregation suppressors that differentiate between nucleation and elongation phases.\n*   The existence of oligogenic models (e.g., ATXN2/NEK1) highlights the complexity of ALS, where pathogenicity may be governed by the synergy of multiple low-penetrance variants rather than monogenic drivers.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

However, the mechanisms linking profibrotic signaling to SOD1 inhibition remain unclear. Here, we identified a pathological copper-COMMD1-SOD1 axis in which intracellular copper overload paradoxically suppressed SOD1 activity. In kidney tissues from chronic kidney disease (CKD) patients and complementary in vivo and in vitro fibrotic models, we consistently observed a reduction in SOD1 activity accompanied by elevated intracellular copper levels.\u00a0Lowering intracellular copper levels restored SOD1 activity, suppressed reactive oxygen species (ROS) accumulation, and alleviated cell senescence and fibrosis. Mechanistically, pathological copper overload impaired SOD1 homodimerization, the essential final step in its activation. We identified copper metabolism MURR1 domain containing 1 (COMMD1) as a key copper-sensitive mediator of this process. Copper overload acted upstream, simultaneously upregulating COMMD1 expression and enhancing its binding affinity to SOD1. This enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function. Collectively, these findings redefined the regulatory role of copper in SOD1 activity and uncovered a previously unrecognized mechanism by which pathological copper overload paradoxically suppressed SOD1 activity via COMMD1-dependent disruption of SOD1 homodimerization, providing new insight into the pathophysiology of copper dyshomeostasis-associated diseases."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

In some cases, misfolding can propagate through a prion-like mechanism whereby natively folded molecules are converted into more copies of the misfolded isoform. Prion-like propagation of misfolding is an attractive therapeutic target, but difficulties with assaying conversion directly and simply have severely limited efforts to find drugs targeting conversion of disease-related proteins. Here, we demonstrate a scalable enzymatic assay for testing potential inhibitors of prion-like conversion in superoxide dismutase-1 (SOD1), whose misfolding is linked to amyotrophic lateral sclerosis (ALS). We tested several small-molecule inhibitors of SOD1 aggregation to determine if they also inhibited prion-like conversion. We found that some compounds, like telbivudine and cisplatin, did indeed significantly delay conversion, but others, like baicalein and quercetin, had little effect. Surprisingly, some compounds, like two statins tested, actually accelerated conversion, suggesting that they might act to promote ALS progression. These results underline the fact that conversion and aggregation are distinct biophysical processes. The ability of the assay to identify compounds effective at delaying prion-like conversion holds out promise for applications in future drug discovery efforts that target propagated misfolding specifically."

This necessitates the development of a methodology that can characterize the conformational states related to protein unfolding and thus allow for the investigation of the molecular mechanism responsible for disease progression. Here, we demonstrate how temperature-controlled nanoelectrospray ionization (TC-nESI) combined with high-resolution ion mobility-mass spectrometry (IM-MS), surface-induced dissociation (SID), and limited proteolysis can be used to define the misfolding and oligomerization landscape of bovine Cu/Zn superoxide dismutase (SOD1). This integrative approach enables real-time detection of coexisting intermediates, and captures molecular events including metal-induced stability, monomer unfolding and assembly into heterogeneous soluble oligomers. Our results reveal that both holo- and apo-SOD1 undergo dimer dissociation followed by monomer misfolding and assembly into heterogeneous non-native oligomers, and that slow thermal ramping promotes the accumulation of misfolded monomers and higher-order complexes. Apo-SOD1 that lacks stabilizing metal cofactors, forms more compact and kinetically distinct oligomers via monomeric, dimeric and trimeric intermediates. Proteolysis and heat-induced fragmentation identify loops V, VI, VII, and the C-terminus as key labile regions contributing to oligomer interface formation, predominantly through hydrophobic interactions. Our findings establish a mechanistically rich model for early aggregation and demonstrate the capability of TC-nESI-IM-MS to temporally and structurally resolve misfolding transitions and oligomeric populations in a single experiment. This platform provides a framework to dissect oligomerization pathways relevant to neurodegenerative diseases."

Genes such as ACE, SOD1 and PER3 play important roles in regulating essential biological functions. These genes are involved in key physiological pathways, including blood pressure regulation, oxidative stress response and circadian rhythm maintenance, and genetic variants within them may influence susceptibility to cancer. Therefore, this study investigates the association between polymorphisms in the ACE, SOD1 and PER3 genes and the risk of breast cancer, with the aim of evaluating how these genetic variations relate to breast cancer susceptibility and clinical outcomes in Jordanian women. Blood samples of 300 women diagnosed with breast cancer, along with 300 healthy participants, were collected, and DNA was extracted from them. Genetic variants in the ACE (rs1799752), SOD1 (rs36232792) and PER3 (rs57875989) genes are examined through employing direct PCR to amplify the target regions. The ACE (rs1799752) variant was observed to be associated with breast cancer susceptibility, with the I/I genotype increasing risk of breast cancer (OR = 5.138, 95% CI = 1.38-19.03, p = 0.014). No associations were observed for SOD1 (rs36232792) and PER3 (rs57875989) variants.

While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS."

However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system."

Although BAFF is a well-known protein in B-cell functions, its role in bronchial cell function remains undefined. Polyinosinic-polycytidylic acid (Poly (I:C)), a synthetic double-stranded RNA, serves as a model for viral infection that binds to toll-like receptor (TLR) 3 to trigger intracellular signal pathways. In this study, we investigated the effect of Poly (I:C)-induced BAFF expression on airway cell migration using Beas-2B human bronchial epithelial cells. Poly (I:C) increased BAFF expression and cell migration, along with the increased expression of N-cadherin, Vimentin and Slug (SNAI2), which are three primary markers for epithelial-mesenchymal transition (EMT). Cell migration was attenuated by small interfering RNA (siRNA) against BAFF, which also inhibited the expression of these EMT markers. Phosphorylation of c-Jun N-terminal kinase (JNK) was enhanced by Poly (I:C) and inhibited by SP600125, JNK inhibitor, leading to a decreased expression of BAFF and aforementioned EMT markers. Poly (I:C) increased reactive oxygen species (ROS), resulting in a ROS-dependent up-regulation of antioxidants (Catalase, superoxide dismutase (SOD)1 and heme oxygenase (HMOX)1) and Nrf2. Pre-treatment with N-acetylcysteine (NAC), ROS scavenger, inhibited Nrf2 activation and JNK phosphorylation. The increase in Nrf2 levels induced by Poly (I:C) was also attenuated by SP600125. Additionally, while NAC treatment inhibited BAFF expression, it caused little change in the expression of the three EMT markers. Increased BAFF expression was confirmed by Nrf2 binding to the BAFF promoter or an increase in the luciferase activity of BAFF promoter co-transfected with Nrf2 plasmids. Treatment with recombinant BAFF protein also increased cell migration and EMT marker expression. Taken together, our results demonstrate that Poly (I:C) promotes a regenerative migration of bronchial epithelial cells by inducing BAFF expression through the ROS-dependent JNK-Nrf2 signaling axis."

The therapeutic focus has moved decisively toward reducing mutant SOD1 protein levels, with intrathecal tofersen emerging as a cornerstone intervention. Clinical data confirm robust target engagement, characterized by significant reductions in cerebrospinal fluid SOD1 protein and plasma neurofilament light chain (NfL) levels. Concurrently, basic research has elucidated the role of copper homeostasis in SOD1 stability, identifying that pathological copper overload can paradoxically suppress SOD1 activity via COMMD1, thereby exacerbating oxidative stress. Moreover, the crosstalk between oxidative stress and neuroinflammation is now viewed as a critical therapeutic target, with hydrogen therapy and immune checkpoint modulation (e.g., LAG-3) showing promise in preclinical models for preserving neuromuscular integrity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Copper Paradox:** High intracellular copper can inhibit SOD1 by disrupting its homodimerization, mediated by COMMD1-dependent mechanisms.\n*   **Catalytic Hydrogen Therapy:** Mutant SOD1 acts as both a Fenton-like agent producing hydroxyl radicals and a catalyst for hydrogen-based free radical scavenging.\n*   **Microglial LAG-3:** This immune checkpoint protein exerts stage-dependent regulation on microglial modules, dissociating inflammatory and phagocytic functions in ALS progression.\n*   **Prion-like Propagation:** Conversion of SOD1 into a misfolded isoform is a targetable biophysical process distinct from aggregation.\n*   **Statin Effects:** While statins can modulate antioxidant genes, they may also inadvertently accelerate prion-like conversion of SOD1 in some experimental contexts.\n*   **Computational Pathology:** Dynamic convolution networks (ODConv) can now distinguish SOD1-associated skeletal muscle pathology from other metabolic disorders using histopathological imagery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Glabridin (Glab), a natural flavonoid derived from licorice, has been shown to mitigate stress-related damage due to its antioxidant properties. This study aims to assess the impact of Glab on OS-induced damage in the bovine immortalized cell line (BIECs-21), validate its effectiveness in vivo, and elucidate the underlying mechanisms. The in vitro OS model of BIECs-21 was established using 400 \u03bcM H2O2. The study evaluated cell viability, lactate dehydrogenase (LDH) activity, oxidative markers, inflammatory responses, and apoptosis in BIECs-21 under various treatment conditions. Additionally, the effects of Glab were investigated in a murine model of experimental colitis induced by dextran sulfate sodium (DSS). Glab improved cell viability, reduced LDH release, and mitigated the adverse effects of H2O2 on total anti-oxidation capacity (T-AOC), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) levels. qRT-PCR analysis revealed that H2O2 exposure resulted in decreased expression of nuclear factor erythroid 2-related factor 2 (Nrf2), superoxide dismutase 1 (SOD1), NADPH quinine oxidoreductase-1 (NQO1), and heme oxygenase-1 (HO-1), while it increased the expression of nuclear factor-kappa B (NF-\u03baB), tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-6 (IL-6), and interleukin-8 (IL-8), ultimately leading to apoptosis in BIECs-21. Notably, Glab supplementation partially reversed these effects. Similar benefits of Glab were observed in a DSS-induced colitis mouse model. Glab reduces OS-induced apoptosis in vitro and in vivo by enhancing antioxidant capacity and reducing inflammation.\n\nID: 42489267\nTitle: A Blood-Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN-Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1.\nAbstract: Peripheral factors that systemically regulate amyotrophic lateral sclerosis (ALS) have remained elusive-until now. Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n\nID: 42479071\nTitle: Effects of six weeks of hypoxia and hypoxic SIT on oxidative stress and myokine responses in skeletal muscle of high-fat-fed ApoE-/- mice.\nAbstract: Atherosclerosis-induced oxidative stress drives skeletal muscle myopathy in peripheral artery disease, yet the combined effects of hypoxia and hypoxia sprint interval training (SIT) remain unclear. The present study was designed to evaluate how a six-week regimen of hypoxia exposure and SIT influences redox balance and myokine production in the skeletal muscle of high-fat diet (HFD) (21% fat, 1.5% (w/w) cholesterol; 43% (w/w) sucrose-free carbohydrate, 4.554\u00a0kcal/g)-fed atherosclerotic ApoE-/- mice. Forty male ApoE-/- mice fed a HFD were randomly assigned to four groups: Control-Normoxia, Control-Hypoxia, SIT-Normoxia, and SIT-Hypoxia. The hypoxia protocol involved exposures to 11.2% oxygen three times (40\u00a0min each) per week. Key assessment parameters included plasma lipid profiles, skeletal muscle reactive oxygen species (ROS), protein carbonyls, key components of the Nrf2 antioxidant pathway, glutathione metabolism, and myokine-related markers. Compared with the control group, both hypoxia and SIT-Normoxia significantly reduced levels of ROS, protein carbonyls, and Vegfa165 mRNA expression in the skeletal muscle. Hypoxia alone enhanced the levels of GSH-synthesizing enzymes and promoted myokine production. SIT-Normoxia improved plasma lipid profiles, activated the Nrf2 pathway, enhanced the GSH system, and upregulated myokines. SIT under hypoxia further reduced ROS and Vegfa165 while increasing plasma HDL-C and levels of SOD1 protein in the skeletal muscle, but failed to synergistically activate the Nrf2 pathway or enhance GSH production. Paradoxically, both intervention combinations suppressed the mRNA expression of myokine precursor Fndc5, BAIBA-synthesizing enzyme Hadh and Hadha. Overall, six weeks of isolated hypoxia exposure or SIT training independently reduced oxidative stress and promoted beneficial myokine responses in the skeletal muscle of ApoE-/- mice fed a HFD. The wild-type (WT) mice fed a low-fat diet (LFD) was included to validate successful induction of hyperlipidemia, vascular remodeling, and skeletal muscle oxidative stress in ApoE-/- mice after six weeks of HFD feeding.\n\nID: 42469634\nTitle: Secretory leukocyte protease inhibitor (SLPI) attenuates TLR4/NF-\u03baB-mediated neuroinflammation in amyotrophic lateral sclerosis: a candidate molecule associated with neuro-pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons. While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.\n\nID: 42467070\nTitle: Pivotal Factors in Breast Cancer Molecular Subtypes Apoptosis Induction by ELF-EMF; Ki-67, ROS Level, HER-2, and SODs.\nAbstract: Although increasing research has shown that extremely low-frequency electromagnetic fields (ELF-EMFs) specifically trigger PCD through the elevation of ROS levels in cancer cells, there is no adequate evidence to determine the exact mechanisms of this phenomenon. The antioxidant machinery may play a crucial role in this area; however, this has been neglected in previous research. The main aim of this study was to assess the effect of ELF-EMF exposure (5\u2009days, 1\u2009Hz, 100\u2009mT, 2\u2009h/day) on ROS levels, expression levels of antioxidant genes, and apoptosis induction in different breast cancer molecular subtypes with different p53 statuses. DCFH-DA results revealed that the ROS level increased in all three cell lines (SKBR-3, MDA-MB-231, and MCF-7); this increase was much greater in SKBR-3 (up to 5-fold compared to its sham exposure). This result was concurrent with the annexin V/PI results; SKBR-3\u2009cells showed much more apoptosis induction (about 78%), compared with the others (22% or 11% in the other two cells). On the other hand, the mRNA expression level of SOD1 and SOD2 increased significantly in the MDA-MB-231, in addition to these two genes, the expression level of SOD3 and GSR increased in the MCF-7\u2009cells but not in the SKBR-3. Taken together, our results confirmed that ELF-EMF induced ROS-dependent apoptosis, especially in HER-2-enriched breast cancer cells (the SKBR-3), in a p53-independent manner. Other molecular subtypes (MDA-MB-231 as TNBC, or MCF-7 as luminal A) showed resistance against the ROS level increasing and subsequent apoptosis induction by using antioxidant genes, especially SOD1.\n\nID: 42465739\nTitle: Development and efficacy of ex vivo expanded autologous regulatory T cells for the treatment of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited therapeutic options, in which neuroinflammation critically drives disease progression. Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.\n\nID: 42458007\nTitle: Oligonucleotide-siRNA conjugate for SOD1 amyotrophic lateral sclerosis: a phase 1 trial.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease partly caused by gain-of-function mutations in superoxide dismutase 1 (SOD1). Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS. ClinicalTrials.gov registration: NCT05903690 .\n\nID: 42450300\nTitle: Transcriptomic Profiling Reveals Inflammatory, Fibrotic, and Apoptotic Signatures in a Methionine-Choline-Deficient Diet-Induced Murine Model of Metabolism-Dysfunction-Associated Steatohepatitis.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH; formerly non-alcoholic steatohepatitis, NASH) is characterized by oxidative stress, inflammatory activation, hepatocellular injury, and progressive liver dysfunction. However, the global transcriptomic landscape underlying stress-induced hepatic injury remains incompletely understood. In this study, we employed a methionine-choline-deficient (MCD) diet-induced murine model to characterize the phenotypic and transcriptomic alterations associated with liver injury. Male C57BL/6J mice were fed either a control or MCD diet, and hepatotoxicity was assessed by survival analysis, body and liver weight measurements, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, histopathological examination, RNA sequencing, quantitative real-time PCR (qRT-PCR), and tumor necrosis factor-alpha (TNF-\u03b1) enzyme-linked immunosorbent assay (ELISA). MCD feeding markedly reduced survival and body weight while inducing hepatomegaly and significant elevations in serum ALT and AST, indicating severe hepatocellular injury. Histopathological analysis demonstrated hepatic steatosis, hepatocellular ballooning, and lobular inflammation without histological evidence of fibrosis. Transcriptomic profiling revealed extensive gene expression remodeling, characterized by activation of inflammatory pathways, enrichment of MAPK-related signaling, dysregulation of lipid metabolism, suppression of antioxidant defense systems, impairment of cytochrome P450-mediated detoxification, and upregulation of apoptosis-associated genes. qRT-PCR further validated the differential expression of representative genes involved in inflammatory signaling (Tlr4, Nfkb1, Nlrp3, and Casp1), MAPK signaling (Fos), xenobiotic metabolism (Cyp4f18), lipid metabolism (Apoa4 and Lpl), extracellular matrix remodeling (Mmp12), and oxidative stress responses (Sod1 and Gstp1). In addition, elevated serum TNF-\u03b1 levels provided protein-level evidence supporting activation of the TLR4/NF-\u03baB/TNF-\u03b1/NLRP3 inflammatory axis. Although fibrosis-associated transcriptional responses were detected, the absence of histological fibrosis suggests transcriptional priming of fibrogenic pathways rather than established fibrogenesis. Collectively, these findings provide a transcriptomic framework linking oxidative stress, impaired detoxification, inflammatory activation, and stress-responsive signaling to MCD-induced hepatic injury. The MCD model provides a valuable experimental platform for characterizing hepatic stress-response transcriptomes and for generating hypotheses that can subsequently be evaluated in environmentally relevant toxicological models. Nevertheless, caution should be exercised when extrapolating these findings to obesity-associated human MASLD, as the MCD model lacks key metabolic features of the human disease, including obesity and insulin resistance. Therefore, the present findings should be interpreted primarily as transcriptomic signatures of stress-induced hepatic injury rather than as a direct representation of the pathophysiological processes underlying human obesity-associated MASLD.\n\nID: 42450273\nTitle: Microvesicle-Derived Redox Signatures as Mediators of Endothelial Dysfunction in Diabetes.\nAbstract: Chronic hyperglycemia and excessive reactive oxygen species (ROS) production are defining features of endothelial dysfunction, a key driver of diabetic vascular complications such as diabetic nephropathy. Microvesicles (MV-enriched fraction), a subtype of extracellular vesicles, and the stress-responsive antioxidant protein Sestrin2 (SESN2) have emerged as important contributors to these processes. This study investigated the role of the MV-enriched fraction in endothelial cell communication under diabetic conditions, with a particular focus on oxidative stress signaling. To model diabetic injury, EA.hy926 endothelial cells were treated with methylglyoxal (MGO), and the resulting MV-enriched fraction was isolated and then applied to two recipient models: na\u00efve endothelial cells and SESN2 knockdown (KD) cells. Protein expression of key antioxidant markers, including endothelial nitric oxide synthase (eNOS), was assessed by Western blot. Nitric oxide (NO) bioavailability was quantified via nitrite measurement using 2,3-diaminonaphthalene (DAN), while mitochondrial and cytosolic ROS levels were evaluated using MitoSOX and dihydroethidium (DHE), respectively. Results demonstrated that the MV-enriched fraction derived from diabetic conditions triggers a complex antioxidant response in healthy endothelial cells, characterized by upregulation of SESN2, superoxide dismutase 1 (SOD1), and heme oxygenase-1 (HO-1). This suggests a compensatory mechanism that mitigates oxidative stress. Notably, SESN2 KD cells exhibited increased ROS production and reduced NO levels upon MV treatment, underscoring the essential role of SESN2 in maintaining redox homeostasis. Overall, this study highlights the dual role of the MV-enriched fraction as a mediator of both protective and detrimental redox signaling in diabetic endothelial dysfunction and suggests potential therapeutic targets for managing diabetic vascular complications.\n\nID: 42450113\nTitle: Serum Copper-to-Zinc Ratio and Oxidative Stress Are Associated with Anemia in Older Adults with Cardiovascular-Kidney-Metabolic Syndrome.\nAbstract: Chronic oxidative stress is a molecular hallmark of cardiovascular-kidney-metabolic (CKM) syndrome, yet its contribution to CKM-associated anemia beyond erythropoietin deficiency and iron restriction is poorly characterized. The serum copper-to-zinc (Cu/Zn) ratio reflects impaired Cu/Zn-SOD1 antioxidant capacity and inflammatory trace-element imbalance, but its relationships with circulating redox biomarkers and its hematological relevance in CKM syndrome has never been explored in a community-dwelling cohort of older adults. We analyzed 2391 NHANES 2011-2016 participants \u2265 50 years of age with CKM stage I-IV. To explore whether the serum Cu/Zn ratio was associated with oxidative stress and immunomodulatory biomarkers as well as with the odds of anemia, we used survey-weighted Spearman correlations, linear regression (outcome: hemoglobin), and logistic regression (outcome: anemia); multivariate models were adjusted for a panel of antioxidant or immunomodulatory biomarkers (selenium, vitamin D), pro-oxidant biomarkers (lead, cadmium, cotinine, uric acid), red cell distribution width (RDW) as a composite biomarker of erythrocyte stress, neutrophil-to-lymphocyte ratio (NLR), CKM stage, and comorbidities. The molecular targets of the nine biomarkers were mapped onto a protein-protein interaction network using the STRING database v12.0 to contextualize regression findings within a systems biology framework. Anemia was present in 205 participants (8.6%). The Cu/Zn ratio was inversely correlated with the antioxidant marker selenium (r = -0.19; p < 0.001) and positively correlated with the pro-oxidant markers RDW (r = +0.21; p < 0.001) and cadmium (r = +0.10; p < 0.001), consistent with its role as a hub within the CKM redox network. In fully adjusted models, a higher Cu/Zn ratio was independently associated with prevalent anemia (OR = 2.94; 95% CI: 1.61-5.37) and lower hemoglobin (\u03b2 = -0.55 g/dL); among included biomarkers, selenium and cadmium were independently protective (OR = 0.76 per 10 \u00b5g/L and 0.23 per \u00b5g/dL, respectively), and RDW and uric acid were independently harmful (OR = 2.20 per 1% and 1.33 per mg/dL, respectively). The Cu/Zn ratio correlated with both antioxidant depletion and pro-oxidant accumulation in CKM syndrome and was independently associated with anemia within this oxidative network. Together with selenium, cadmium, RDW, and uric acid, it defines an oxidative stress-driven hematological pathway that may contribute to the development and progression of anemia in patients with CKM syndrome.\n\nID: 42447970\nTitle: Human umbilical cord-derived mesenchymal stem cells ameliorate muscle dysfunction and metabolic dysregulation in the CuZnSOD null mouse model of sarcopenia.\nAbstract: Age-related sarcopenia is a progressive skeletal muscle disorder driven by oxidative stress and metabolic dysregulation. Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.\n\nID: 42447123\nTitle: Neuromuscular ultrasound as a biomarker in the SOD1 mouse model of amyotrophic lateral sclerosis.\nAbstract: A progression marker that indicates early disease-related changes and treatment responses in the to date incurable neurodegenerative disease amyotrophic lateral sclerosis (ALS) is highly desirable. Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.\n\nID: 42442802\nTitle: The Role of Genetic Alterations in the Emergence of Alzheimer's Disease in Down Syndrome: A Review.\nAbstract: Down syndrome (DS), the most common chromosomal disorder, is associated with an accelerated aging process, increasing the risk of early-onset Alzheimer's disease. This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers.\n\nID: 42442304\nTitle: Amelioration of obesity-induced testicular dysfunction and structural damage by ganoderma lucidum polysaccharides and triterpenoids in rats: Correlation with Nrf2-mediated antioxidant response.\nAbstract: Obesity is a global health crisis and a critical risk factor for male infertility, impairing testicular structure and function through hormonal imbalance and oxidative stress. Current therapeutic strategies are often unsatisfactory due to limited efficacy or adverse effects. This study investigated the protective effects and potential molecular mechanisms of Ganoderma lucidum (GL) polysaccharides and triterpenoids against testicular injury in high-fat diet-induced obese male rats. After 12-week GL intervention, reproductive function in obese male rats showed improvement: GL increased litter size, improved sperm motility, reduced sperm DNA fragmentation, and restored serum testosterone, inhibin B, and leptin levels. It also alleviated testicular histopathological damage, downregulated PPT1, and maintained vimentin expression. Notably, GL facilitated delayed fertility recovery and showed a trend toward improved cumulative reproductive success, although fixed-time pregnancy rates were not significantly changed. Mechanistically, GL is associated with enhanced Nrf2 pathway activity, increased SOD1, HO-1, NQO1, and GPX4 levels, and decreased MDA and ROS accumulation, thereby attenuating oxidative stress. It preserved mitochondrial integrity, suppressed germ cell apoptosis (downregulating Bax and caspase-3, upregulating Bcl-2), and promoted cell proliferation. These findings indicate that GL polysaccharides and triterpenoids effectively ameliorate obesity-induced testicular dysfunction, and these beneficial effects are associated with Nrf2-mediated antioxidant responses, mitochondrial homeostasis, apoptosis regulation, and hormonal balance. GL may serve as a promising candidate for obesity-related male infertility.\n\nID: 42432986\nTitle: Mitoquinone Prevents Cardiac Dysfunction by Normalizing Mitochondrial ROS and Calcium Handling in Acute Myocardial Infarction.\nAbstract: Acute myocardial infarction (MI) is the leading cause of heart failure (HF). However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI. Male Wistar rats were divided into four experimental groups: Sham, Infarct, Sham+MitoQ, and Infarct+MitoQ. MitoQ was administered orally (8\u2009mg/kg/dia) for 7\u2009days. Hemodynamic parameters, infarct area, papillary muscle contractility, cardiomyocyte mechanics, Ca2+ transients, and total and mitochondrial superoxide (DHE and MitoSOX) were assessed. After 7\u2009days of MI, rats exhibited impaired contractility, altered inotropic response to extracellular Ca2+, cardiomyocyte hypertrophy, and increased total and ROSm. MitoQ prevented body weight loss and significantly improved hemodynamic parameters compared to the Infarct group. In papillary muscles, MitoQ restored basal isometric force and the inotropic response to extracellular Ca2+. In cardiomyocytes, it attenuated hypertrophy, preserved shortening, and reduced ([Ca2+]i) transient amplitude. MitoQ significantly decreased total and mitochondrial O2\u2022- production. It selectively reduced NOX1 expression under simulated conditions but did not significantly affect NOX2, SOD1, or catalase expression in the context of MI. MitoQ prevented contractile dysfunction, suggesting that mitochondrial oxidative stress plays a decisive role in myocardial dysfunction during the acute phase of MI. Targeting antioxidant therapy to the mitochondria represents a promising strategy for preventing post-infarction heart failure and opens new perspectives for the development of more effective interventions in the treatment of cardiovascular diseases.\n\nID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the \u03b11 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.\n\nID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.\n\nID: 42425334\nTitle: Comparative screening of Amur tiger cytokines identifies IL-15 as a cytoprotective candidate against feline panleukopenia virus infection.\nAbstract: Comparative studies of species-derived cytokines remain limited in endangered carnivores. We cloned six immune-related cytokines from Amur tigers (Panthera tigris altaica), with sequence analysis revealing >90% identity across Felidae. Among all tested cytokines, IL-15 demonstrated superior and sustained lymphocyte-stimulatory activity at 200\u202fng/mL. To investigate antiviral potential, F81\u202fcells were pretreated with IL-15 and challenged with feline panleukopenia virus (FPV). Mechanistic studies revealed that IL-15 attenuated virus-induced apoptosis by modulating key regulatory proteins: downregulating pro-apoptotic factors (Bax, Caspase3/9, p53, Cytc) while upregulating anti-apoptotic Bcl-2. Additionally, IL-15 preserved mitochondrial integrity by maintaining membrane potential, enhancing fusion proteins (MFN1/MFN2), and suppressing fission protein Drp1. IL-15 also strengthened cellular antioxidant defenses through increased SOD1/SOD2 expression, significantly reducing reactive oxygen species (ROS) accumulation. These protective effects persisted for 48\u202fh post-infection, demonstrating sustained cytoprotective effects. These findings reveal species-specific IL-15-mediated antiviral mechanisms within the Felidae family and provide comparative insights into how immune defenses are optimized in species with constrained evolutionary history, with implications for understanding carnivore immune evolution and conservation medicine.\n\nID: 42419058\nTitle: Redox Imbalance and Impaired Protein Clearance Drive Chronic Liver Injury in Biliary Atresia.\nAbstract: Excessive or uncontrolled generation of reactive oxygen species (ROS) is closely associated with the development of liver diseases. However, direct evidence linking oxidative stress to impaired hepatic function in human biliary atresia (BA) remains limited. To address this, we performed bulk RNA sequencing to investigate (1) alterations in hepatic oxidative stress and antioxidant defense mechanisms and (2) transcriptomic changes associated with impaired hepatic function in BA. Total RNA was extracted from liver samples of patients with BA and non-BA cholestasis. Bulk RNA sequencing and transcriptomic analyses were performed, focusing on redox-related pathways and genes linked to hepatic function. Dual oxidases 1 and 2 were significantly upregulated in BA. In contrast, key ROS-metabolizing enzymes such as catalase, glutathione synthetase, and superoxide dismutase 1 and 2 were downregulated, indicating redox imbalance in BA livers. Excessive ROS can lead to the denaturation of cellular proteins and damage to organelles, which are normally degraded via autophagy and proteasomes. However, both autophagy and proteasome functions were impaired in BA, contributing to sustained inflammation and further ROS production. Transcriptomic analyses also revealed repression of core liver transcription and splicing factors, indicating injury-associated alterations in hepatic transcription programs. BA is characterized by a redox imbalance and dysfunctional protein clearance, forming a vicious cycle of ROS accumulation and inflammation. These changes likely contribute to liver fibrosis and the progressive loss of hepatic function in BA.\n\nID: 42402967\nTitle: Hypoxia-preconditioned dental pulp stem cells alleviate acetaminophen-induced liver failure via promoting MYC-HIF1A/HIF-1\u03b1-BNIP3-mediated mitophagy.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is a prevalent clinical liver condition caused mostly by oxidative stress and mitochondrial damage. Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot.\n\nID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n\nID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n\nID: 42397005\nTitle: Covalent Modulation of Protein Misfolding and Aggregation Processes in the Context of Neurodegenerative Diseases.\nAbstract: Misfolded protein aggregates represent major histopathological hallmarks of neurodegenerative diseases, differing in the structural components and brain regions affected. Furthermore, the formed assemblies act as key players in developing and fostering neurotoxic processes, with distinct mechanisms depending on the stage of the amyloid cascade. Particularly, the oligomer intermediates are now considered as the main drivers of neurotoxicity, thus requiring an early antiaggregant therapeutic intervention to achieve a significant neuroprotective efficacy. Among different strategies, direct interaction at early stages preventing aggregation is quite intricate due to the considered undruggability of misfolded monomers. In this context, a covalent approach targeting specific functional nucleophilic residues within disordered proteins can offer an intriguing opportunity to overcome these weaknesses. Therefore, in this review, we outline covalent modulators of misfolding and aggregation processes reported to date, referring to the major misfolded proteins in the neurodegenerative context (i.e., \u03b2-amyloid, tau, \u03b1-synuclein, and superoxide dismutase 1) to highlight their potential both as valuable pharmacological tools or therapeutic perspectives.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42390843\nTitle: Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis.\nAbstract: Superoxide dismutase 1 (SOD1), a copper-dependent antioxidant, is essential for redox homeostasis, and its decline drives renal senescence and fibrosis. However, the mechanisms linking profibrotic signaling to SOD1 inhibition remain unclear. Here, we identified a pathological copper-COMMD1-SOD1 axis in which intracellular copper overload paradoxically suppressed SOD1 activity. In kidney tissues from chronic kidney disease (CKD) patients and complementary in vivo and in vitro fibrotic models, we consistently observed a reduction in SOD1 activity accompanied by elevated intracellular copper levels.\u00a0Lowering intracellular copper levels restored SOD1 activity, suppressed reactive oxygen species (ROS) accumulation, and alleviated cell senescence and fibrosis. Mechanistically, pathological copper overload impaired SOD1 homodimerization, the essential final step in its activation. We identified copper metabolism MURR1 domain containing 1 (COMMD1) as a key copper-sensitive mediator of this process. Copper overload acted upstream, simultaneously upregulating COMMD1 expression and enhancing its binding affinity to SOD1. This enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function. Collectively, these findings redefined the regulatory role of copper in SOD1 activity and uncovered a previously unrecognized mechanism by which pathological copper overload paradoxically suppressed SOD1 activity via COMMD1-dependent disruption of SOD1 homodimerization, providing new insight into the pathophysiology of copper dyshomeostasis-associated diseases.\n\nID: 42387584\nTitle: SGK1-mediated deficits in microglial phagocytosis drive pathological progression in amyotrophic lateral sclerosis.\nAbstract: Alterations in microglial function and transcriptomic profiles are major pathological hallmarks of amyotrophic lateral sclerosis (ALS). However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.\n\nID: 42385849\nTitle: Quercetin and carvacrol act synergistically to inhibit Candida albicans biofilms in vitro via membrane disruption and oxidative stress.\nAbstract: Candida albicans biofilms are a major cause of device-associated infections and treatment failure due to high antifungal tolerance. Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200\u202f\u03bcg/mL (carvacrol) and 240\u202f\u03bcg/mL (quercetin) to 17\u202f\u03bcg/mL and 10.9\u202f\u03bcg/mL, respectively (FICI\u202f=\u202f0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by \u223c64.4% (vs. \u223c56.5% for carvacrol and \u223c51.5% for quercetin alone) and inducing apoptosis-like cell death with robust metacaspase activation supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established.\n\nID: 42385392\nTitle: Biological responses of human astrocytes (SVGp12) and glioblastoma (A172) cells to dendronized \u03b2-cyclodextrin molecular containers: Morphological and molecular insights.\nAbstract: The search for molecular containers that enhance the bioavailability of active substances has opened the development of functionalized \u03b2CD-based molecular containers. In this study, the effects of \u03b2CD-modified with dimethylolpropionic acid (Bis-MPA) dendrons (\u03b2CD-m2G and \u03b2CD-m3G) were evaluated in SVGp12 (non-tumor astrocytes) and A172 (glioblastoma) cells. The dendronized systems exhibited low cytotoxicity (>75% viability) even at high concentrations (90\u00a0\u03bcM, p\u00a0<\u00a00.05). Morphological analyses revealed lipid inclusion bodies (LIBs), suggesting that after intracellular uptake, the dendronized containers promote their formation. \u03b2CD-m3G occupies 12% of the cell volume in SVGp12 and 17% in A172 (p\u00a0<\u00a00.05). Ultrastructural evaluation showed increased smooth endoplasmic reticulum (SER), a finding consistent with enhanced lipid metabolism. Importantly, cell differentiation and endoplasmic reticulum stress, evaluated by the expression of Aquaporin-4 and calnexin, were not impaired (p\u00a0>\u00a00.05). A twofold increase in mGlu-5 expression (p\u00a0<\u00a00.001) was observed in both cell lines due primarily to the \u03b2CD-m3G container. Because neither container induces oxidative stress in the SVGp12 cell line, cell proliferation increases from 41% to 48% (p\u00a0<\u00a00.001) due to \u03b2CD-m2G and \u03b2CD-m3G, respectively. These cells also increased Caspase9 expression (p\u00a0<\u00a00.001), suggesting control of proliferation. However, \u03b2CD increased NRF2 expression by 4.3-fold (p\u00a0<\u00a00.0001) and the expression of SOD1, HMOX1, and PRDX1. \u03b2CD increases 1.8-fold-ROS in A172 cells (p\u00a0<\u00a00.001) versus control. 3.5-fold expression of NRF2 was observed in the presence of NAC (p\u00a0<\u00a00.001). These suggest that only \u03b2CD increases NRF2 and ROS as an adaptive response of A172 cells. The incorporation of amphiphilic dendritic groups enables efficient cellular uptake of \u03b2CD-dendronized containers.\n\nID: 42384769\nTitle: Carbon monoxide-releasing vesicles provide rapid and sustained inhibition of inflammatory pain in mice.\nAbstract: Carbon monoxide (CO) is an important modulator of chronic pain, but its clinical use remains limited. To enhance its therapeutic potential, we developed a vesicular CO-releasing system based on a carbonyl metallosurfactant (PCOL6) and soy phosphatidylcholine (SPC) and evaluated its physicochemical properties, as well as its in silico and in vivo effects on inflammation-induced nociception and muscle impairment in male C57BL/6 mice. The metallosomes exhibited a uniform size distribution, stability upon dilution, and a predominantly single membrane, indicating their suitability for therapeutic applications. Computational simulations revealed that PCOL6 can mix with phospholipids to form stable lamellar structures with thinner and more disordered bilayers than those of pure phospholipid membranes. In vivo experiments showed that acute administration of PCOL6/SPC vesicles inhibited complete Freund's adjuvant (CFA)-induced allodynia faster and longer than tricarbonyldichlororuthenium (II) dimer, Ru2Cl4(CO)6 (CORM-2). Repeated metallosome treatment was also more effective than CORM-2 at reducing allodynia, hyperalgesia, and inflammation-related muscle deficits. Both CO releasers normalized CFA-induced NOD-like receptor protein 3 inflammasome overexpression, increased heme oxygenase 1 (HO-1) and NAD(P)H quinone dehydrogenase 1 expression, and maintained elevated superoxide dismutase 1 levels in paw tissues; notably, HO-1 induction was greater in PCOL6/SPC-treated mice. These findings suggest that PCOL6/SPC metallosomes represent a promising therapeutic strategy for chronic inflammatory pain. Vesicles bearing a CO-releasing metallosurfactant (PCOL6) inhibit inflammatory pain.The analgesic effect of PCOL6/SPC is higher and lasts longer than that of CORM-2.PCOL6/SPC exerts anti-inflammatory and antioxidant effects.\n\nID: 42384233\nTitle: Genome-wide spectrum of coding DNA variations in Indian patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited therapies, emphasizing the need for deeper understanding of disease pathogenesis. While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.\n\nID: 42383461\nTitle: Acute Exposure to Environmentally Relevant Concentrations of Ciprofloxacin and Levonadifloxacin Alters Behavior, Organ Health, and Stress Response in Adult Zebrafish.\nAbstract: Antibiotic pollution in aquatic systems is an emerging global concern, but the sublethal effects of acute exposure on aquatic vertebrates are poorly understood. This study examined the acute toxicity by exposing adult zebrafish to three concentrations (1, 5, and 10\u2009mg/L) of ciprofloxacin (CIP) and levonadifloxacin (LND) for 96\u2009h. Behavioral, histological, biochemical, and transcriptional changes were assessed. In the novel tank-dive test, both antibiotics induced concentration- and time-dependent anxiogenic behaviors, such as reduced exploration, decreased total distance traveled, and less time in the upper zone. Histopathological analysis showed progressive tissue damage beginning in the gill epithelium and spreading to the intestine and muscle. Overall, lesion severity increased with higher concentrations and was consistently higher in CIP-exposed fish. Antioxidant enzyme activity exhibited significant changes in superoxide dismutase, catalase, and glutathione peroxidase 1. Early increase in enzyme levels at 48\u2009h coincided with reduced transcription of sod1, cat1, and gpx1a. At 96\u2009h, transcription levels increased while protein levels remained stable. Pathway analysis grouped these genes within interconnected oxidative stress networks rather than cell death pathways. Overall, the results indicate that exposure to both fluoroquinolones for 96\u2009h causes a staged oxidative stress response, along with behavioral disruptions and tissue damage. CIP caused stronger immediate biological effects than LND at the same concentrations, although both antibiotics disturbed organismal homeostasis at sublethal levels. These findings highlight the ecological importance of short-term antibiotic contamination and demonstrate the value of multiple endpoints for detecting early toxic effects in aquatic organisms.\n\nID: 42381517\nTitle: Proteomic Profiling of Cryopreservation-Induced Alterations in Rhesus Macaque Sperm.\nAbstract: Sperm cryopreservation is a fundamental technique in assisted reproductive technologies. While human sperm freezing is clinically routine, preserving nonhuman primate sperm remains challenging due to species-specific characteristics and low post-thaw viability. This study aims to investigate the proteomic changes in rhesus macaque sperm before and after cryopreservation, focusing on identifying the molecular mechanisms behind cryoinjury. Semen was collected from six sexually mature male rhesus macaques (6-10 years) using rectal electroejaculation. Motility parameters were quantified pre- and postcryopreservation using computer-assisted semen analysis (CASA) with vapor-phase liquid nitrogen protocols. Data-independent acquisition (DIA) quantitative proteomics, combined with LC-MS/MS, was used to profile global protein expression changes. Differential protein analysis was performed using multibioinformatics tools for functional annotation and network modeling. Papanicolaou and acridine orange (AO) staining were used to assess sperm morphology and DNA integrity, while reactive oxygen species (ROS) assay and immunofluorescence were employed to validate the proteomic analysis results. We identified 512 differentially expressed proteins (32 upregulated, 480 downregulated), which are predominantly enriched in pathways related to metabolic reprogramming, oxidative stress response, and protein homeostasis. Immunofluorescence staining further confirmed markedly reduced levels of SOD1, PGK2, PKC\u2011alpha, and phospho\u2011tyrosine in sperm after freeze-thaw cycling. These molecular hubs are associated with sperm motility and functional stability and may be essential for regulating energy metabolism, oxidative balance, and proteotoxicity during cryopreservation-induced stress in rhesus macaque sperm. Cryopreservation induces profound proteomic remodeling in rhesus macaque sperm, mitochondrial electron transport, and metabolic homeostasis. Our findings reveal conserved and species-specific cryoinjury mechanisms, offering molecular targets for optimizing cryopreservation protocols in nonhuman primates to advance reproductive conservation strategies.\n\nID: 42375957\nTitle: Application of nano-selenium as a dietary supplement and its effects on antioxidant status and gene expression related to oxidative stress in broiler chickens.\nAbstract: Antioxidants are important factors in reducing stress in poultry birds. Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers.\n\nID: 42375949\nTitle: Reactive oxygen species and intrinsic apoptotic markers in thyroid dysfunction: Insights from experimental animal models.\nAbstract: Thyroid disorders are associated with elevated reactive oxygen species (ROS) levels that trigger apoptosis. Nevertheless, the precise connection between ROS levels and apoptotic markers in thyroid dysfunction remains unclear. To explore the relationship between ROS levels and intrinsic apoptotic (IA) markers in thyroid homogenates derived from hypothyroidism and hyperthyroidism mouse models. Eighteen male Wistar rats, each weighing 240 \u00b1 10 g, were allocated to three groups of six rats. Hypothyroidism and hyperthyroidism were induced over 8 weeks using 0.05% Propylthiouracil (PTU) and 0.0012% Levothyroxine (L-Thy), respectively. T3, T4, and thyroid-stimulating hormone levels were measured, and thyroid size and body weights were recorded. The levels of ROS markers [MDA, glutathione (GSH), SOD-1, CAT, and GPX) and IA markers (Bax, Bcl-2, and caspase-3) were assessed in tissue homogenates. A gradual weight loss was observed in the hyperthyroidism group compared with the control group. The hypothyroid model showed elevated MDA levels and cleaved caspase-3, as well as a higher Bax/Bcl-2 ratio, whereas GSH, SOD-1, CAT, GPX, and Bcl-2 levels were lower than those in the control group (p < 0.05). In contrast, no changes were observed in the hyperthyroid models. Thyroid hormone levels are inversely correlated with ROS and positively correlated with antioxidant levels. Hypothyroidism models exhibited increased oxidative stress and pro-apoptotic markers, suggesting the initiation of apoptosis and cellular damage. Conversely, the hyperthyroid models showed no such changes.\n\nID: 42375616\nTitle: Effects of the glucagon-like peptide-1 receptor agonist liraglutide on retinal endothelial function and oxidative stress during sepsis.\nAbstract: To test the hypothesis that the glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide improves retinal vascular function in mice with polymicrobial sepsis. Three groups of mice were studied. Two groups underwent cecal ligation and puncture to induce polymicrobial sepsis. One received vehicle and the other liraglutide via intraperitoneal injection starting 24\u00a0h before the procedure and continuing twice daily until euthanasia. A third group underwent sham surgery and served as control. Forty-eight hours after sepsis induction, mice were euthanized and retinas were isolated for ex vivo assessment of vascular function by videomicroscopy. In addition, reactive oxygen species (ROS) formation and gene expression were evaluated using dihydroethidium staining, quantitative real-time PCR, and immunostaining of NADPH oxidase (NOX)1 and NOX2, respectively. Endothelium-dependent vasodilation to acetylcholine was markedly impaired in retinal arterioles of septic, vehicle-treated mice but was partially preserved in liraglutide-treated septic mice. In contrast, vasodilation to the endothelium-independent vasodilator sodium nitroprusside was similar across all groups. Dihydroethidium staining revealed increased ROS signals in retinal arterioles, the ganglion cell layer, the inner and outer nuclear layers, and the optic nerve of septic, vehicle-treated mice. These increases were attenuated by liraglutide treatment. Furthermore, retinal mRNA expression of NOX1 was significantly upregulated in septic, vehicle-treated mice but remained at control levels in liraglutide-treated septic mice. . In addition, mRNA levels of SOD2, nNOS, and PAI-1 were increased, whereas NOX4, COX-2, and UCP-2 were decreased in septic, vehicle-treated mice. Liraglutide treatment was associated with increased mRNA expression for the antioxidant enzymes SOD1 and SOD3, reduced expression for MCP-1, ICAM-1 and PAI-1 mRNA levels and restoration of UCP-2 mRNA expression. Immunoreactivity for NOX1, but not NOX2, was increased in retinal blood vessels of septic mice. Treatment with liraglutide attenuates endothelial dysfunction, reduces oxidative stress, and suppresses NOX1 upregulation in the retina during polymicrobial sepsis. These findings highlight the preventive and therapeutic potential of GLP-1 receptor agonists for retinal vascular complications associated with sepsis and systemic inflammation.\n\nID: 42375264\nTitle: Proteomic profile of seminal plasma in tropical Saanen bucks under heat stress using 1D-SDS PAGE.\nAbstract: Tropical heat and humidity induce oxidative and thermal stress that threaten male fertility. However, the seminal plasma mechanisms that sustain sperm function under these conditions in goats remain poorly understood. This study aimed to evaluate semen quality and characterize the seminal-plasma proteome of Saanen bucks raised under Indonesia's tropical conditions to identify molecular adaptations associated with fertility resilience. Three healthy bucks (five ejaculates each) were examined using computer-assisted sperm analysis (CASA) for sperm motility, viability, abnormality, membrane and acrosome integrity, and kinematics. Seminal-plasma proteins were separated by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and annotated through Gene Ontology enrichment. While most semen traits and kinematics were comparable among bucks, abnormality and acrosome integrity differed significantly (p < 0.05). A conserved extracellular, vesicle-associated proteome was identified-including BSP1, BSP3, BSP5, ANXA5, ALB, HSPA1A, HSP90AA1, CLU, GPX5, and SOD1-with minor inter-individual variation in LTF, FN1, SPP1, and A2M. Enrichment (FDR < 0.05) highlighted the extracellular region, vesicle, and cytokine-regulatory pathways. This study provides the first proteomic evidence of seminal plasma adaptation to THS in Saanen bucks, revealing a stable core of chaperone, antioxidant, and membrane-coating proteins that safeguard sperm function. These findings establish a novel proteomic basis for heat-resilient fertility and support the development of protein-based sire selection and reproductive management tools in tropical dairy-goat systems.\n\nID: 42375253\nTitle: Chlorella vulgaris improves fertility in malnourished male rats by regulating the oxidative state, spermatogenesis, and inflammatory cytokines.\nAbstract: Malnutrition is one of the predisposing factors of disturbance in some physiological functions, including reproductive health. Currently, many people and animals are globally facing micronutrient deficiency, especially in lands with poor soils in organic matter and nutrients. Egyptian soil and, consequently, crops were found to be deficient in micronutrients to varying degrees. This study aimed to investigate the potential fertility-enhancing effects of the microalgae Chlorella vulgaris (CV) on male rats fed a salt-deficient diet. Forty-five adult rats (15 rats each) were divided into three groups (G1, G2, and G3). G1 received a normal balanced diet, G2 received a salt-deprived diet (SD), and G3 was supplemented with SD plus Chlorella 1% of the diet (SD + CV). After eight successive weeks of treatment, the animals were fasted overnight, anesthetized, and sacrificed. The collected plasma was analyzed for organ function-related constituents, oxidative biomarkers, and testosterone levels. Epididymal sperms were also examined. Samples of testis were analyzed for quantitative gene expression of GPX4, SOD1, and SPATA6 genes. Additionally, histopathological examination was performed for testis, liver, and kidney samples. The results obtained from the current study revealed that the plasma of the SD group had higher levels of oxidative biomarkers and inflammatory cytokines, elevated urea, creatinine, and uric acid levels, and liver enzymes, and lower testosterone levels than the normal control group. In addition, lower sperm motility and higher abnormality and downregulation of SPATA6 genes and degenerative changes were found in the testes, liver, and kidneys. The administration of (SD + CV) restored these alterations. CV could be used as a supplement to compensate for nutrient or salt deficiency and correct the resultant disorders, especially reproductive affections, in males.\n\nID: 42375252\nTitle: Impact of cinnamon oil supplementation on broiler performance, intestinal health, gene expression, antioxidant capacity, and hematological parameters.\nAbstract: Cinnamon oil, used as a feed additive in poultry, enhances growth performance, improves antioxidant status, and augments immune response, resulting in superior meat quality and general productive efficiency. This study aimed to assess the effect of cinnamon oil (CO) in broiler diets on growth efficiency, hematological parameters, gene expression, and histological condition. Two hundred sixteen one-day-old broilers were assigned to three treatments in a fully randomized design, with each treatment subdivided into six replicates of 12 chicks. The first treatment is a control group, and the second and third are basic diets with 0.3% and 0.6% CO, respectively. The 0.3% CO group had a higher final body weight, with no significant differences (p \u2265 0.05) in body weight and body weight gain. Birds in this group consumed less FI, leading to a notable improvement in feed conversion rate compared to the control. Additionally, 0.3% CO significantly (p \u2264 0.05) reduced total cholesterol levels without major impacts on most blood parameters, although mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration increased in treated groups. Significant changes were observed in lipase and amylase levels, as well as higher catalase levels and lower malondialdehyde levels. Both 0.3% and 0.6% CO treatments (p \u2264 0.05) increased IGF-1, IL-10, and superoxide dismutase 1 levels, with the 0.6% concentration showing the highest levels. IL-1\u03b2 levels remained low, indicating a specific effect of CO supplementation. Moreover, in the 0.3% CO group, CO supplementation enhanced intestinal absorption by increasing villus height and crypt depth. Adding 0.3% CO to the diet improves feed efficiency, lowers cholesterol, improves blood parameters, lowers inflammation, boosts antioxidant enzymes, and optimally improves intestinal structure, which is beneficial for poultry health and performance.\n\nID: 42364425\nTitle: Effects of SGLT2 inhibitor dapagliflozin on the heart of rats with long-standing Type 1 diabetes mellitus: Protein profile.\nAbstract: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have beneficial outcomes on the renal and cardiovascular system in diabetes mellitus (DM) patients. As most clinical trials were performed in Type 2 DM, the effects of SGLT2 inhibition in Type 1 DM are not completely clarified. To evaluate the effects of long-standing SGLT2 inhibitor dapagliflozin on the protein profile in rats with a Type 1 DM model. Male Wistar rats were divided into Control (C), DM, and DM treated with dapagliflozin (DM+DAPA) for 30 weeks. DM was induced by a single injection of streptozotocin (40\u202fmg/kg); dapagliflozin was added to chow (5\u202fmg/kg/day). Label-free mass spectrometry was used to assess left ventricular proteome. The bioinformatic tools used were STRING, Cytoscape, Cluster Marker, and ClueGO. ANOVA and Tukey or Kruskal-Wallis and Dunn. Dapagliflozin attenuated body weight loss (C 574\u202f\u00b1\u202f43; DM 339\u202f\u00b1\u202f31*; DM+DAPA 413\u202f\u00b1\u202f30*# g; p\u202f<\u202f0.05 * vs C; # vs DM) and reduced glycemia [C 108 (101-111); DM 554 (529-562)*; DM\u202f+\u202fDAPA 343 (237-416)*# mg/dL; p\u202f<\u202f0.05 * vs C; # vs DM]. Most proteins identified in the networks downregulated in DM vs C were upregulated in DM\u202f+\u202fDAPA vs DM. Proteins related to energy metabolism (CKm, Ak1, Atp5pf, Mdh1, Idh2), excitation-contraction coupling (Actc1, Casq2, Serca1, Serca2a), and oxidative stress (Sod1, Sod2) were upregulated in DM\u202f+\u202fDAPA. KEGG pathways enriched in DM vs Control included gap junction, necroptosis, and fatty acid degradation (upregulated), and Alzheimer's disease, cardiac contraction, and glycolysis/gluconeogenesis (downregulated). In DM\u202f+\u202fDAPA vs DM, upregulated pathways included Parkinson's disease, cardiac contraction, citrate cycle, necroptosis, and cyclic guanosine monophosphate-dependent protein kinase (PKG) signaling pathway; downregulated proteins were linked to ketone body metabolism. Dapagliflozin modulates cardiac protein abundance by attenuating DM-induced changes in Type 1 DM rats.\n\nID: 42362003\nTitle: Astragalus polysaccharides alleviate oxidative damage by activating the Keap1-Nrf2 antioxidant pathway through miR-183-5p in a fish cell model.\nAbstract: Astragalus polysaccharides (APS), one of the star antioxidants among traditional Chinese medicine, have widespread applications in healthcare, veterinary, and fishery fields. However, the mechanisms underlying their antioxidative action remain largely unknown. In this study, the protective role of APS in H2O2-induced oxidative damage and associated mechanism were investigated in large yellow croaker head kidney (LYCK) cells. We found that the APS significantly inhibited H2O2-induced cytotoxicity, ROS accumulation, and mitochondrial damage, thereby alleviating subsequent apoptosis and pyroptosis. Further studies showed that APS activated the Keap1-Nrf2 antioxidant signaling pathway, thus up-regulating the downstream antioxidant genes (SOD-1, CAT, HO-1, and GR), enhancing SOD-1 and CAT activities and T-AOC level, and decreasing MDA content. Mechanistically, APS activate this antioxidant signaling pathway by inducing the expression of microRNA-183 (miR-183-5p). The produced miR-183-5p binds to the 3'UTR of Keap1 mRNA and promotes its degradation, leading to consequent Nrf2 activation. Our results therefore unveil the mechanism by which APS alleviate oxidative damage in a fish cell model, and provide the theoretical basis for their application in aquaculture.\n\nID: 42359357\nTitle: Innate immune crosstalk in ALS/FTD pathogenesis.\nAbstract: Marked by protein aggregation, impaired proteostasis, organelle stress, and chronic neuroinflammation, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) form a clinically, genetically, and pathologically overlapping disease spectrum. Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.\n\nID: 42356470\nTitle: Adenosine A2A Receptors Mediate Resveratrol-Induced Nrf2 Activation and Cytoprotection Against Oxidative Stress in HeLa Cells.\nAbstract: Background/Objectives: Oxidative stress is a major contributor to cellular injury in many pathological conditions, including neurodegenerative disorders. Resveratrol, a natural polyphenol with antioxidant properties, has been proposed as a cytoprotective compound, although the molecular mechanisms underlying its effects remain incompletely understood. Here, we investigated whether the protective action of resveratrol against hydrogen peroxide-induced oxidative stress is mediated by adenosine receptor signalling and activation of the Nrf2 pathway in HeLa cells. Methods: Cells were treated with resveratrol alone or in combination with selective adenosine receptor antagonists and oxidant challenge, and cell viability, ROS production, receptor involvement, and Nrf2 expression and localization were analyzed. Results: Resveratrol at a non-toxic concentration significantly protected HeLa cells against oxidative damage, reduced ROS accumulation, promoted Nrf2 nuclear translocation and gene expression, and enhanced the gene expression of antioxidant enzymes such as SOD1, catalase, HO-1, and NQO1. Pharmacological blockade of the A2A receptor prevented this protective effect, whereas the inhibition of A1 and A3 receptors enhanced it and avoided the increased SOD1, catalase, HO-1, and NQO1 gene expression promoted by resveratrol alone. Moreover, A2A antagonism was associated with reduced PKA levels, consistent with the involvement of the cAMP/PKA signalling axis. Conclusions: Taken together, these observations support a model in which adenosine A2A receptor signalling contributes to resveratrol-associated cytoprotection and Nrf2 activation in a human non-neuronal cell model. Our findings therefore provide mechanistic insight into resveratrol-adenosine receptor interactions and generate hypotheses to be tested in disease-relevant neuronal systems.\n\nID: 42437952\nTitle: NOP56 is essential for mammalian generation and maintenance of multiple central nervous systems, associated with SCA36 pathology.\nAbstract: NOP56, a core nucleolar component involved in small nucleolar ribonucleoprotein assembly, has been genetically implicated in spinocerebellar ataxia type 36. However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097.\n\nID: 42353210\nTitle: Selective Alterations of Thiol Redox Homeostasis and Antioxidant Enzyme Activity in Advanced Atherosclerosis.\nAbstract: Atherosclerosis is a progressive vascular disease characterized by lipid-rich plaque accumulation, oxidative stress, and chronic inflammation, contributing to coronary heart disease, stroke, and peripheral arterial disease. This study investigated the impact of inflammation, vascular calcification, and statin therapy on redox balance in blood and carotid artery plaques, aiming to identify potential biomarkers for disease assessment. Thirty-two patients undergoing carotid endarterectomy provided 34 plaque samples. Enzyme activities in plaque/erythrocytes and -SH group concentration in plasma/plaque were measured. Pathological analysis was performed to determine inflammation/calcification grade, the presence of mast cells and plaque composition. The results showed that mast cells were associated with reduced non-protein -SH groups, indicating selective thiol consumption and serving as a qualitative marker of oxidative burden. Reduced catalase activity in erythrocytes was associated with advanced calcification, pointing to long-standing systemic oxidative stress. Statin therapy enhanced systemic superoxide-dismutase 1 activity, increased -SH groups, and modulated plaque-specific glutathione reductase activity, attenuating sex-related differences in redox regulation. These findings highlight the complex interplay between systemic and local oxidative processes in atherosclerosis through alterations in redox-related biomarkers such as plasma -SH group concentrations and catalase activity.\n\nID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\n\nID: 42351997\nTitle: Green-Extracted Ficus carica L. Fruit Polysaccharides Promote Longevity in Caenorhabditis elegans via Modulation of SKN-1 and IIS Pathway.\nAbstract: In this study, polysaccharides from Ficus carica L. fruits (FCPs) were extracted using a deep eutectic solvent (DES)-based ultrasound-assisted extraction (UAE) method. The physicochemical properties of the FCPs were then characterized, and the anti-aging effects of FCPs were evaluated in Caenorhabditis elegans (C. elegans). It was demonstrated that FCPs significantly extended the lifespan of the nematodes, while improving locomotor activity without affecting the body size or reproductive capacity. Meanwhile, FCPs reduced lipofuscin accumulation, decreased intracellular reactive oxygen species (ROS) levels, and increased the survival of C. elegans under oxidative stress. Moreover, FCPs upregulated the expression of antioxidant genes sod-1, sod-3, ctl-2, ctl-3 and gst-4. The expression of skinhead-1 (skn-1), a homologue gene of mammalian nuclear factor erythroid 2-related factor (Nrf) in C. elegans, was also elevated upon FCPs treatment. Knockdown of skn-1 expression by RNA interference abolished the lifespan extension and ROS reduction in FCPs-treated C. elegans, indicating that the SKN-1-mediated signaling was essential for the anti-aging effects of FCPs. Additionally, FCPs caused downregulation of the key components of the insulin/IGF-1 signaling (IIS) pathway, age-1, akt-1, and akt-2. Overall, these results suggested that FCPs promoted longevity in C. elegans via modulation of SKN-1 and IIS pathway.\n\nID: 42341648\nTitle: Processing-dependent hepatic risk and benefit of Polygonum Multiflorum Radix: Integrated chemical profiling, in vivo validation and candidate quality control markers.\nAbstract: To clarify how steaming and sun-drying cycles affect the hepatic risk-benefit profile of Polygoni Multiflori Radix (PMR), the herb was processed with black bean decoction for 1-9 cycles following the traditional \"nine steaming and nine sun-drying\" protocol. UPLC-MS analysis showed that anthraquinones and trans-THSG progressively decreased with increasing cycles and stabilized after five cycles, whereas cassialactone-8-O-\u03b2-D-glucoside and hyperoside emerged as new components during processing. In a low-dose LPS-sensitized mouse model mimicking immune-idiosyncratic liver injury, PMR processed for three or more cycles significantly alleviated liver damage. In an acetaminophen (APAP)-induced acute liver injury model, PMR processed for 5-7 cycles exhibited the strongest hepatoprotective effects. Spectrum-effect correlation analysis identified twelve constituents (e.g., emodin-8-O-\u03b2-D-glucoside) associated with liver injury, involving targets related to drug metabolism (CYP3A4), membrane transporters (ABCB1, SLC2A1), and oxidative stress (SOD1). Five components (e.g., cassialactone-8-O-\u03b2-D-glucoside) were linked to hepatoprotection, potentially through modulation of synthetic function (ALB) and inflammatory response (TNF, EGFR, HSP90AA1). The Cellular Thermal Shift Assay (CETSA) was employed to validate the molecular docking results, demonstrating that emodin-8-O-\u03b2-D-glucopyranoside and physcion-8-O-\u03b2-D-glucoside significantly enhanced the thermal stability of TP53. In parallel, emodin and hyperoside were confirmed to increase the thermal stability of albumin (ALB). Overall, processing PMR with black bean decoction for 5-7 cycles is optimal for reducing hepatic risk while preserving or enhancing hepatoprotective activity. These findings support a risk-benefit-oriented processing standard and propose candidate quality markers for standardized manufacturing, including trans-THSG, emodin, aloe-emodin, cassialactone-8-O-\u03b2-D-glucoside, and hyperoside.\n\nID: 42327062\nTitle: Effects of oxidative stress and aging on nerve, muscle, and synapse in a male-specific abdominal neuromuscular junction in Drosophila.\nAbstract: Defects in Drosophila Cu 2+ /Zn 2+ superoxide dismutase (encoded by the gene Sod1 ) lead to elevated oxidative stress and a drastically shortened lifespan. To contrast the effects of aging and oxidative stress on nerve conduction, synaptic transmission, and muscle excitability, we developed an easily accessible adult abdominal neuromuscular preparation, utilizing the male-specific Muscle of Lawrence (MOL) in Drosophila . The large size of MOL facilitated analyses of presynaptic nerve signals and postsynaptic responses that could result in sizable excitatory junctional potentials (EJPs) evoking full-blown muscle action potentials (APs) which were terminated rapidly by a characteristic afterhyperpolarization (AHP). Aged wild-type (WT) individuals (80 days or older) exhibited diminished neuromuscular transmission, mainly reflecting declines in motor axon conduction, with synaptic transmission remaining largely intact (since robust EJPs could still be evoked when nerve terminals were directly stimulated electrotonically). Additionally, muscle APs showed enhanced depolarizing peaks and weakened AHPs during current injection, suggesting weakening in repolarizing K + currents. Chronologically younger Sod1 mutants (up to 30 days) displayed similar trends of neuromuscular changes, confirming a major role of oxidative stress in aging. However, certain distinctions exist in muscle membrane properties and transmitter release machinery. A clear increase in muscle membrane resistance was seen in Sod1 but not in aged WT. Additionally, unlike normal spontaneous release of synaptic vesicles leading to miniature EJPs (mEJPs), extremely enlarged spontaneous transmitter discharges occurred in aged WT but was never seen in Sod1 , indicating a distinct, aging-specific alteration in transmitter release regulation. Notably, our work revealed considerable variation among individuals, ranging from transmission failure to largely intact neuromuscular functions, demonstrating the stochastic nature of functional declines due to aging and oxidative stress. Moreover, this study uncovered a well-defined common vulnerability, i.e. weakening of the Ca 2+ -activated BK current that caused drastic reduction in AHP in both aged WT and Sod1 mutants, as confirmed by their diminishing sensitivity to the BK channel blocker paxilline, which caused striking alterations in the AHP in WT control.\n\nID: 42320547\nTitle: Proteomic analysis reveals early pathological defects in corticospinal motor neurons of a spastin model of hereditary spastic paraplegia, which are improved by NU-9 treatment.\nAbstract: Upper motor neuron (UMN) degeneration is a characteristic feature of hereditary spastic paraplegia (HSP), a genetically heterogeneous heritable neurodegenerative disorder resulting from mutations in over ninety genes. The mutations in the SPAST gene, which encodes the microtubule-severing protein spastin, are responsible for about 40% of all HSP cases. To date, the cellular and molecular mechanisms linking mutant spastin protein to UMN vulnerability in HSP patients remain unknown and there are no disease modifying therapies. To address this knowledge gap, we isolated pure populations of corticospinal motor neurons (CSMN; a.k.a. UMN in mice) from SPASTC448Y-UeGFP reporter mice at two pre-symptomatic time points and performed bottom-up proteomic analyses to reveal changes in their proteome that informs the underlying causes of their initial vulnerability. We find dynamic changes in their proteome and that limitations with cytoarchitectural integrity and stability of key organelles contribute to their neuronal vulnerability. Since the compound NU-9 was shown to improve similar cellular problems in CSMN that are diseased due to misfolded SOD1 toxicity and TDP-43 pathology, we further investigated its effect on the well-established pathological features of HSP that are recapitulated in the SPASTC448Y mice. We find that NU-9 treatment (100\u00a0mg/kg, for 100\u00a0days) significantly prevented degeneration of corticospinal axons, restored the integrity of mitochondria and endoplasmic reticulum, and reduced the presence of electron-dense accumulations in the CSMN of SPASTC448Y mice.\n\nID: 42305046\nTitle: Lactiplantibacillus plantarum HY7715 Attenuates Oxidative Stress-Induced Neurobiological Aging-Related Changes by Modulating Senescence-Associated Markers and Gut Microbiota.\nAbstract: External stressors can accelerate biological aging-related processes by promoting oxidative stress and senescence-associated molecular alterations in the brain. This study investigated the potential of Lactiplantibacillus plantarum HY7715 to attenuate oxidative stress-induced neurobiological aging-related changes using H2O2-induced HT22 hippocampal cells and a restraint-stressed mouse model. In HT22 cells, HY7715 reduced reactive oxygen species accumulation, decreased 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels, and lowered the proportion of senescence-associated \u03b2-galactosidase-positive cells. These effects were accompanied by suppression of p53/p21 signaling and restoration of Tert expression. In restraint-stressed mice, HY7715 reduced the number of p21-positive cells in the hippocampus, significantly lowered p53 expression, restored Tert expression, reduced Il-6 expression, and improved antioxidant-related gene expression, including Gpx1 and Sod1. Microbiome analysis showed that HY7715 reshaped the stress-altered gut microbiota toward a Lactobacillus-enriched profile and reduced the abundance of Lachnospiraceae, Acetatifactor, Desulfovibrio, and Oscillibacter. Collectively, these findings suggest that HY7715 may attenuate oxidative stress-induced neurobiological aging-related changes by modulating senescence-associated molecular markers and stress-altered gut microbiota, highlighting its potential as a candidate for supporting healthy brain aging.\n\nID: 42302989\nTitle: Establishment and characterization of Hanwoo cumulus cell line for heat stress studies.\nAbstract: Heat stress (HS) negatively affects cattle reproduction, decreasing livestock productivity. HS response in cattle reproductive cumulus cells remain understudied due to limited cell lines and comprehensive omics data. This study aims to establish immortalized cumulus cells from Hanwoo cattle as a HS model and explores their HS response using molecular markers including transcriptomics and proteomics approaches. Immortalized cumulus cells were established from primary cumulus isolated from fresh Hanwoo cattle follicles by using piggyBac transposon-mediated SV40T expression system. HS condition was optimized using reactive oxygen species (ROS) detection, quantitative reverse-transcription polymerase chain reaction, and Western blotting on oxidative and endoplasmic reticulum stress markers under different HS and recovery periods (4 h, 12 h, and 24 h). Transcriptomic and proteomic data were generated to identify HS-related differentially expressed genes (DEG) and proteins (DEP) utilized for gene ontology (GO) and pathway enrichment analysis. We established the first immortalized cumulus cell line with high specificity (99% CD44[+]) for in vitro HS study. ROS accumulation was observed at 4 h HS, leading to immediate upregulation of HSP70 and BiP proteins, with oxidative stress gene expression (SOD1, CAT, GPX1) peaked at 12 h HS. We identified 754 DEGs (fold change\u2265|2|) and 357 DEPs (fold change\u2265|1.5|) related to HS in the cumulus cell line. Enrichment analysis exhibited upregulation in GO and pathways related to protein unfolding and cellular response to HS, respectively, from both the DEG and DEP list. Downregulated DEG and DEP showed significant enrichment in GO related to the extracellular matrix, potentially affecting cumulus-oocyte complex communication for reproductive function. The cumulus cell line serves as a robust in vitro model for studying HS response in cattle reproductive system. The multi-omics data could help clarify the comprehensive HS response and identify possible molecular targets to mitigate negative HS effects in the future.\n\nID: 42277589\nTitle: Redox Imbalance and NOS-Dependent Modulation of Superoxide in the Bladder Mucosa of Women With IC/BPS: A Preliminary Study.\nAbstract: Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a chronic condition characterized by bladder/pelvic pain and urinary symptoms, with poorly defined mechanisms and no reliable biomarkers. Oxidative stress, particularly reactive oxygen species (ROS), has been implicated in its pathophysiology, but direct human evidence remains scarce. Here, we evaluated ROS- and nitric oxide (NO)-related pathways in bladder mucosa from women with IC/BPS (n\u2009=\u20095) and controls (n\u2009=\u20097). Gene expression of NO-cGMP components, NADPH oxidases (NOX1-5), and antioxidant enzymes was assessed by qPCR. Baseline NO and superoxide (   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  ) levels were quantified using histochemical assays, and the effects of pharmacological inhibitors of NOS, iNOS and NOX enzymes were examined. IC/BPS samples displayed increased expression of PDE5A (3.1-fold) and p47phox (1.6-fold), along with reduced SOD1 expression (0.39-fold), consistent with an oxidative imbalance. Although baseline   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  did not differ between groups, NOS inhibition with L-NAME markedly reduced   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  generation, with a greater effect in IC/BPS tissue (85% reduction). Conversely, selective iNOS inhibition (1400\u2009W) increased   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  levels in IC/BPS biopsies. These findings suggest altered NOS-dependent redox regulation in the IC/BPS mucosa. Despite the limited sample size inherent to human biopsy studies, these results provide preliminary evidence of redox dysregulation in IC/BPS mucosa and highlight   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  as a relevant mediator. They support further investigation into therapeutic strategies targeting NOS redox balance and cGMP signalling.\n\nID: 42267104\nTitle: Oxidative stress response of Saccharomyces cerevisiae exposed to different molecular weight of polycyclic aromatic hydrocarbons.\nAbstract: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants that cause adverse health effects. This study investigated the toxic effect of different molecular weight PAHs on eukaryote model organism (Saccharomyces cerevisiae) exploiting oxidative stress biomarkers as endpoint indicators. Yeast cells were treated with environmentally relevant concentrations of phenanthrene (PHE), fluoranthene (FLA), and benzo[ghi]perylene (BghiP) for 24\u202fh. Benzo[a]pyrene (BaP) was used as a positive control. Subsequently, expression of genes related to oxidative stress responses, cytotoxicity via targeted analysis of antioxidant mutants, generation of reactive oxygen species (ROS), superoxide dismutase (SOD) activity, and glutathione (GSH) content were assessed. The results demonstrated that viability of S. cerevisiae was related to the molecular weight of PAHs. Oxidative stress related genes SOD1 and SOD2 were found to be prominently expressed. According to the redox mechanism of action, BghiP and BaP triggered ROS formation and induced an increasing activity of SOD. Furthermore, PAH exposure significantly affected the glutathione levels. In summary, PAHs clearly caused oxidative stress. Among PAH samples, the more benzene ring contained more toxicity level exerted in yeast cells.\n\nID: 42250300\nTitle: Gunshot residue PM2.5 exposure: Cardiopulmonary effects and the role of RAGE signaling in inflammation and oxidative stress.\nAbstract: Gunshot residue (GSR) is an airborne mixture of chemicals and particles released after firearm discharge. There is limited information on cardiopulmonary effects of GSR specifically in a health relevant size fraction. This study evaluates the acute cardiopulmonary effects of GSR (particles \u22642.5\u202f\u00b5m; GSR PM2.5) and investigates the role of the receptor for advanced glycation end-products (RAGE) signaling cascade in the mediation of inflammation and oxidative stress using wild-type (WT) and RAGE knockout (RKO) mice. GSR PM2.5 collected during a law enforcement pistol training contained characteristic GSR markers (lead, copper, and 2,4- dinitrotoluene). Right ventricle measurements were lower in the GSR PM2.5 treated animals compared to the control indicating potential pulmonary vasodilation regardless of genotype. Lead content in the heart was significantly higher in the GSR PM2.5 exposed mice, indicating systemic circulation. Inflammatory markers (NF-\u03baB, TNF-\u03b1, SOD-1 and 2) in the lungs of RKO animals were significantly lower compared to the WT groups. The cardiovascular effects, differential inflammatory expression, and influence of RAGE signaling pathway on the cardiorespiratory response to GSR PM2.5 highlight the need for further investigation of longer exposure durations, mechanistic influences, and a more extensive chemical characterization of GSR PM2.5 in toxicological assessments.\n\nID: 42239390\nTitle: A Liver-Targeted Copper Supplement Reduces Metabolic Dysfunction-Associated Liver Steatosis by Increasing Lipolysis and Fatty Acid Oxidation.\nAbstract: Metabolic-associated steatotic liver disease (MASLD) is a prevalent liver disease driven by complex dysregulation of hepatic lipid metabolism. Here we show that copper deficiency is a nutrient vulnerability in steatotic liver disease and that selective liver-targeted copper supplementation can reduce excess lipid accumulation. Analysis of steatotic patient and mouse tissues identify widespread alterations in hepatic copper homeostasis markers. Integrated multi-omics analyses reveal that copper induces lipolysis of PLIN2-containing lipid droplets while lipid importer CD36 is downregulated. We show that copper inhibits cAMP hydrolase activity of PDE3B, thus activating PKA-mediated HSL and AMPK activation upstream of lipolysis. Fatty acids liberated through lipolysis are subsequently degraded via enhanced mitochondrial fatty acid oxidation, supported by energetic rewiring toward oxidative phosphorylation (OXPHOS) with increased copper-dependent complex IV and SOD1 activity. Our findings establish a multi-pronged mechanism by which hepatic copper supplementation coordinately regulates lipid metabolism in response to steatosis and unveils a therapeutic metallomedicine strategy to rewire lipid regulation. Liver-targeted copper supplementation reduces diet-induced liver steatosis by dual activation of lipolysis and fatty acid degradation pathways.\n\nID: 42239283\nTitle: Chronic diazepam reveals excessive homeostatic gain in SOD1G93A mouse spinal motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\n\nID: 42236915\nTitle: Integrated molecular, microRNA, and biochemical profiling reveals oxidative stress-driven degeneration of the ligamentum flavum in lumbar spinal stenosis.\nAbstract: Degenerative lumbar spinal stenosis (LSS) is driven by fibrosis and hypertrophy of the ligamentum flavum (LF). Oxidative stress-an excess of reactive oxygen species (ROS) over antioxidant defenses-may underlie LF remodeling, but tissue-level evidence is limited. LF from patients with LSS (n\u2009=\u2009180) and controls (n\u2009=\u2009102) underwent transcriptomic microarray and microRNA (miRNA) profiling, reverse-transcription quantitative PCR (RT-qPCR), enzyme-linked immunosorbent assay (ELISA), and biochemical assays of thiobarbituric acid-reactive substances (TBARS), total glutathione (GSH), and glutathione peroxidase (GPx) activity. Protein-protein interaction (PPI) and functional enrichment analyses were performed. Among 14,130 oxidative-stress-related transcripts, 8,197 were differentially expressed (p\u2009<\u20090.05). Redox-sensitive inflammatory mediators were upregulated, including tumor necrosis factor (TNF), interleukin-1\u03b2 (IL-1B), interleukin-6 (IL-6), and C-X-C motif chemokine ligand 8 (CXCL8), alongside mitogen-activated protein kinases (MAPK8/JNK1, MAPK14/p38\u03b1, MAPK1/ERK2) and superoxide dismutase 2 (SOD2) and peroxiredoxin-1 (PRDX1). Antioxidant defenses-catalase (CAT), superoxide dismutases SOD1/SOD3, glutathione peroxidase-1 (GPX1), and sirtuin-3 (SIRT3)-were downregulated. RT-qPCR confirmed these trends. ELISA demonstrated higher MAPK8 and IL-6 and lower SIRT3 and GPX1 in hypertrophic LF (all p\u2009<\u20090.05). Biochemically, LSS tissue showed increased TBARS and GPx activity and decreased GSH versus controls; oxidative imbalance intensified with greater pain and higher body mass index. Selected miRNAs (e.g., hsa-miR-3163\u2192MAPK8, hsa-miR-4291\u2192SIRT3) were reduced. PPI networks were highly enriched (p\u2009<\u20091\u2009\u00d7\u200910\u207b\u00b9\u2076). Notably, MAPK8, SIRT3, GPX1, and IL-6 dysregulation was independent of pain category. LF in LSS exhibits a persistent ROS-driven, MAPK-amplified inflammatory program with mitochondrial vulnerability (SIRT3 loss) and impaired peroxide detoxification (GPX1 decline). This oxidative signature likely sustains fibrosis and LF thickening and nominates MAPK8-SIRT3-GPX1-IL-6 as candidate biomarkers and therapeutic targets.\n\nID: 42227128\nTitle: [Organ-Specific Changes in the Expression of Inflammatory Response and Antioxidant Defense Genes in the Late Period after Hemorrhagic Shock].\nAbstract: Hemorrhagic shock (HS) is a life-threatening condition that leads to multiple organ failure due to centralization of blood flow and impaired blood clotting. In this study, we investigated the acute and delayed effects of HS on the brain, kidneys, and liver of rats to identify molecular targets for therapy of the consequences of shock. Blood acid-base balance and electrocardiography (ECG) parameters were studied in rats in the acute phase of HS. Gene expression of antioxidant enzymes (Gpx1, Sod1, Cat, Nfe2l2) and inflammatory markers (Ptprc, Cxcl1, Cd86, Itgal, Il1b, Il6, Tnf, Tlr2, Cox2, Cst7, Ccl3, Il10) in brain, kidney, and liver tissues was analyzed, as well as the amount of protein markers for kidney damage (NGAL, KIM-1) in urine 24 h after HS. In addition, markers for the activation of astrocytes (Gfap) and microglia (Aif1) as well as neuronal markers (Eno2, Tubb3) in brain tissue were analyzed. Biochemical markers for liver and kidney damage and total antioxidant activity were determined in blood serum. Acute HS caused decompensated lactic acidosis, arterial hypotension and characteristic changes in the ECG. Although no pronounced inflammatory response was detected in brain, kidney and liver tissue in the late phase after acute blood loss, the brain and liver tissue were more susceptible to the adverse effects of acute blood loss than the kidneys according to a number of indicators. This points to the need to develop targeted strategies to protect organs in the postresuscitation period by targeting specific molecular targets in specific tissues.\n\nID: 42226995\nTitle: Antibacterial Photodynamic Therapy Using Zinc Phthalocyanine Against Multidrug-resistant Pseudomonas aeruginosa in Burn Infections.\nAbstract: Due to the prevalence of MDR strains, alternative treatments such as antimicrobial photodynamic therapy (aPDT) have received much attention. This technique is an innovative technology that utilizes photosensitizers and generates active oxygen species. This study aimed to investigate the effectiveness of aPDT against multidrug-resistant (MDR) Pseudomonas aeruginosa using a nanoemulsion containing zinc phthalocyanine (NE/ZnPc) in a burn wound model under both in in vitro and in vivo conditions. Optimization of PDT conditions -across different drug concentrations, different incubation times, different doses of laser radiation -was performed in vitro, and then the anti-biofilm effects of the optimal concentration against clinical isolates of MDR P. aeruginosa were investigated. Under in vivo conditions, male rats were divided into seven groups: Control, burn wound group, bacterial-infected burn wound, infected burn wound with laser treatment, infected wound treated with laser and drug (optimal concentration), infected wound treated with drug alone, and infected wound treated with nanoemulsion alone. The area of the burn wound was measured at the beginning and end of the experiment. Pieces of skin tissue were collected to perform histological studies and measure the expression of EGFR and SOD1 genes. Based on the results, the drug at a concentration of 40 \u00b5g/mL encapsulated in nanoemulsion, a laser dose of 13 J/cm2, and the incubation time of 2 hours were selected as optimal conditions. Under these conditions, 80% biofilm inhibition was observed. According to the histological results, NE/ZnPc-mediated aPDT and laser radiation reduced the burn wound area, significantly accelerated the wound healing process, increased EGFR gene expression, and decreased SOD1 gene expression to normal levels. The promising antibacterial and anti-biofilm activity of NE/ClZnlPc-mediated aPDT against MDR P. aeruginosa, along with the increased expression of EGFR and SOD1 levels in infected rat wounds, indicate that this treatment may be served as an alternative approach to eradicate MDR bacteria.\n\nID: 42196191\nTitle: Longitudinal CSF and Serum Biomarker Dynamics in Tofersen-Treated SOD1-ALS: A Real-World Multicentre Cohort Study.\nAbstract: Tofersen is a gene-targeted therapy for superoxide dismutase 1 (SOD1)-associated amyotrophic lateral sclerosis (ALS), but neurofilament light chain (NfL) may not fully capture the biological response to treatment. We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression. These findings suggest that longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.\n\nID: 42194081\nTitle: Epigenetic Evidence Implies Disturbed Proteostasis and Potentially Protein Aggregation in Suicidality.\nAbstract: Suicide is a major public health concern and cause of death worldwide. While progress has been made in understanding molecular pathways involved in suicide, much more work is needed to identify clinically useful biomarkers of suicidality. Disturbed cellular proteostasis and aggregation of specific misfolded proteins are established pathological factors of neurodegenerative diseases. Increasing evidence also suggests that such aggregates often occur in patients with chronic mental illnesses. Recently, genes related to disturbed proteostasis showed differential methylation in individuals who died by suicide compared to controls. These include five genes encoding proteins that aggregate in neurodegenerative and/or mental illness: CRMP1 (also called DPYSL1), DISC1, MAPT (encoding the Tau protein), PRKN (also called PARK2, encoding Parkin), and SOD1. Given the possibility that altered methylation in these genes could affect expression of the proteins they encode, we aimed to review evidence for whether disturbed proteostasis may be a point of overlap between suicidality, neurodegenerative disease, and/or mental illnesses. Epigenetic changes in most of these genes also occur in other neurological disorders. Autophagy, and, to a lesser extent, the ubiquitin-proteasome system, are emerging as potentially impaired in individuals with suicidal tendencies and individuals who died by suicide. Based on this accumulated data, we hypothesise that disturbed proteostasis is likely to be a pathological component of suicidality. It is also plausible that this may lead to the accumulation of aggregated proteins in a similar manner to, and potentially overlapping with, those seen in major mental illnesses. If true, this would have consequences for potential identification of biomarkers for suicidality and should be a priority for future research in the field.\n\nID: 42173382\nTitle: Tofersen in SOD1-associated amyotrophic lateral sclerosis: From molecular mechanisms to regulatory milestones.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a progressive and ultimately fatal neurodegenerative disorder characterized by degeneration of upper and lower motor neurons. Mutations in the superoxide dismutase 1 (SOD1) gene account for approximately 2% of ALS cases and are associated with toxic protein misfolding and aggregation. Tofersen is an antisense oligonucleotide therapy designed to reduce the synthesis of mutant SOD1 protein through targeted mRNA degradation. While this strategy represents a gene-specific therapeutic approach for a subset of ALS patients, evidence regarding its efficacy, effectiveness and long-term outcomes continues to be evaluated in clinical trials and post-marketing studies. First, to describe the molecular mechanisms underlying SOD1-associated ALS and second, to analyze the therapeutic development, clinical outcomes, and regulatory evolution of tofersen. A narrative review was conducted in PubMed on preclinical and clinical studies published from 2016 through late 2025, complemented by an analysis of public registries and regulatory documentation. Clinical trials were identified through ClinicalTrials.gov and the Clinical Trials Information System (CTIS), and official reports from the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) were reviewed to contextualize their development and regulatory evaluation. Fifty-three publications were identified, of which 20 met predefined inclusion criteria after screening and full-text review. Preclinical studies showed reduced mutant SOD1 expression and prolonged survival in transgenic models. Phase I-II trials demonstrated safety, favorable pharmacokinetics, and dose-dependent reductions in SOD1 in the cerebrospinal fluid and plasma neurofilament light chain (NfL) levels. Although the phase III VALOR trial did not meet the primary ALSFRS-R endpoint (a validated questionnaire-based functional rating scale-revised for determining ALS disease progression) at 28 weeks, significant reductions in the surrogate biomarker NfL indicated target engagement and supported accelerated regulatory approval. Extension data suggested potential clinical benefit with early treatment. Ongoing studies, including ATLAS in presymptomatic carriers, and real-world European data support continued evaluation, alongside accelerated regulatory approvals by FDA and EMA. Tofersen marks a paradigm shift in ALS management, establishing the foundation for precision medicine in neurodegenerative diseases. Its ongoing evaluation in the ATLAS trial will determine whether early intervention can prevent or delay disease onset in presymptomatic SOD1 mutation carriers.\n\nID: 42165865\nTitle: Molecular mechanisms underlaying fluoride-induced neurotoxicity: interplay of antioxidants and endoplasmic reticulum stress-mediated apoptotic pathways in rats.\nAbstract: Fluoride is a naturally occurring compound widely present in soil, water, rocks and is essential to maintain the physiological function and structure of bones and teeth. However, chronic exposure to elevated fluoride levels has been linked to adverse neurological effects. Despite its widespread environmental presence, the molecular mechanisms underlying fluoride-induced neurotoxicity remain incompletely understood. This study aimed to elucidate the effects of fluoride on oxidative stress, endoplasmic reticulum (ER) stress, apoptosis, and associated histopathological alterations in brain tissue. Forty Sprague-Dawley rats were randomly assigned to four groups (n\u2009=\u200910 per group; 5 male\u2009+\u20095 female) and administered sodium fluoride (NaF) in drinking water at concentrations of\u2009<\u20090.5\u00a0ppm (control), 50\u00a0ppm, 150\u00a0ppm, and 300\u00a0ppm for 90 consecutive days. The expression of antioxidant genes (SOD1 and GCLC), ER stress, and apoptosis-related genes (XBP1, GRP78, BCL-2, and BAX) was quantified using real-time quantitative PCR (RT-qPCR), and histopathological analysis of the brain tissues was performed. Fluoride exposure caused a dose-dependent downregulation of antioxidant and ER stress-related genes and concurrent upregulation of the pro-apoptotic genes. Histopathological analysis revealed structural damage in hippocampus and cerebral cortex, including neuronal shrinkage, vacuolization, and apoptotic features. These findings indicate that prolonged NaF exposure impairs antioxidant defenses, induces ER stress, and activates apoptotic pathways, thereby contributing to neuronal damage. This study provides mechanistic insights into fluoride-induced neurotoxicity and highlights the need for further research on potential therapeutic strategies targeting oxidative and ER stress pathways.\n\nID: 42163674\nTitle: Unraveling the Pathological Mechanisms and Biomarkers of Amyotrophic Lateral Sclerosis: A Comprehensive Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an devastating neurodegenerative disorder with a very fast course and a very high fatality rate. The review discusses the intricate pathophysiology of ALS, such as the alterations caused by the genetic mutations of the C9orf72 and SOD1 genes, the misfolding and aggregation of proteins, oxidative stress, the excitotoxicity of glutamate, neuroinflammation, malfunctions in mitochondria, and axonal transport. Heterogeneity of the disease makes the development of biomarkers in ALS challenging; however, some promising candidates have been identified. Protein aggregation markers, including TDP-43 and SOD1, oxidative stress markers, such as 8-oxodG, neuroinflammatory markers, such as CRP and MCP-1, and neurological injury markers, such as NfL and pNfH, have potential in diagnosis, monitoring, and prediction. The miRNAs and particular metabolites can also provide clues to the molecular basis of ALS. The creation of biomarkers is challenged by the presence of a significant amount of disease heterogeneity and the lack of animal model reliability. The review highlights the importance of further research on biomarkers aimed at improving the diagnosis, treatment, and development of drugs for ALS. It supports the concept of a systematic biomarker development process, including genetic testing and molecular subgroup analysis, to enhance diagnostic accuracy and prognostic prediction capabilities. Exploring the interrelationship between the pathological process of ALS and the treatment based on multi-biomarker strategies is crucial for achieving effective management of this disease. As our understanding of ALS deepens, we expect to discover more new biomarkers in the future. This will significantly improve the diagnosis, treatment, and overall management of this devastating diseas.\n\nID: 42156174\nTitle: COMMD1 Induces Copper Deficiency of SOD1 by Inhibiting the Palmitoylation of CCS in ALS.\nAbstract: Mutations in superoxide dismutase 1 (SOD1) compromise its metal-binding capacity, resulting in protein misfolding and aggregation, which ultimately induces cellular apoptosis in amyotrophic lateral sclerosis (ALS). Copper metabolism domain containing 1 (COMMD1), a gene implicated in copper homeostasis, has not been thoroughly characterized in the context of ALS pathogenesis. In this study, we identified elevated COMMD1 expression in ALS, potentially contributing to diminished copper incorporation into SOD1. Knockdown of COMMD1 enhanced palmitoylation of the copper chaperone for SOD1 (CCS), facilitating its membrane translocation and promoting copper loading into SOD1, thereby conferring neuroprotection in ALS. Mechanistically, we established that COMMD1 knockdown augments CCS palmitoylation via activation of the hypoxia-inducible factor 1 subunit alpha (HIF-1\u03b1)/fatty acid synthase (FASN) signaling axis. In vivo investigations utilizing male hSOD1G93A transgenic mice demonstrated that COMMD1 deficiency markedly ameliorated the deterioration of motor function and prolonged survival duration. These findings collectively suggest that COMMD1 represents a potential therapeutic target for ALS intervention.\n\nID: 42155840\nTitle: Protective role of SIRT1 activation against retinal injury caused by polystyrene micro/nanoplastics exposure.\nAbstract: Plastic particles are persistent environmental pollutants that can accumulate in ocular tissues and potentially contribute to retinal damage. Sirtuin 1 (SIRT1), a key regulator of oxidative stress and cellular senescence, may play a protective role against plastic-induced retinal injury, but its role remains unclear. In this study, human retinal pigment epithelial (RPE) cells and rat retinas were directly exposed to polystyrene microplastics (PS-MPs, 2\u00a0\u03bcm) and nanoplastics (PS-NPs, 50\u00a0nm), with and without SIRT activator SRT1720. In vitro analyses included cell viability, intracellular reactive oxygen species (ROS), SIRT1 expression, antioxidant enzyme levels (SOD1, SOD2, CAT), and senescence were assessed. In vivo, rats received intravitreal injections of plastic particles, with or without SRT1720 and oxidative stress-related markers, SIRT1 expression, and senescence were evaluated in retinal tissues 7 days after injection. Results showed that PS-MPs and PS-NPs reduced RPE cell viability in a dose- and time-dependent manner, suppressed SIRT1 and antioxidant enzymes, and increased ROS and senescence. PS-NPs induced stronger ROS and senescence than PS-MPs in vitro. Co-treatment with SRT1720 restored SIRT1 expression, improved antioxidant responses, and attenuated ROS and senescence. In vivo, both particle types induced retinal changes similar to those observed in cell experiments. However, there was no significant toxicity difference between PS-MPs and PS-NPs. In conclusion, PS-MPs or PS-NPs promote oxidative stress and senescence in RPE cells and retinal tissue via downregulation of SIRT1 and antioxidant defenses, while SRT1720 provides protective effects. These findings SIRT1 as a potential therapeutic target for plastic-induced retinal injury.\n\nID: 42148602\nTitle: When copper turns killer: Decoding copper dyshomeostasis and cuproptosis in neurodegenerative pathogenesis and precision metal interventions.\nAbstract: Copper is an essential cofactor for neuronal metabolism, enzymatic functions, and neurotransmission. However, copper dyshomeostasis-induced redox activity makes the brain vulnerable to oxidative and proteostatic stress. Cuproptosis, a recently characterized form of programmed cell death, is triggered by copper binding to lipoylated enzymes of the tricarboxylic acid cycle, resulting in proteotoxic stress, mitochondrial dysfunction, and cell death. Given that mitochondria are central to copper handling and the primary site of cuproptosis, we examine mitochondrial pathways and key cuproptosis-related genes. We also assess disease-specific signatures of copper imbalance. In Alzheimer's disease, excess copper binds to amyloid-\u03b2, promoting aggregation and neurotoxicity. In Parkinson's disease, copper-bound \u03b1-synuclein fosters aggregation, while copper-driven redox cycling elevates reactive oxygen species. Cuproptosis worsens mitochondrial vulnerability in Parkinson's disease and impairs cellular stress responses in Huntington's disease. In amyotrophic lateral sclerosis, superoxide dismutase 1-related defects compromise antioxidant defenses alongside copper-dependent mitochondrial dysfunction. In prion diseases, copper facilitates prion protein misfolding and toxicity. Across these disorders, common features include mitochondrial dysfunction and cuproptosis hallmarks-such as enhanced protein lipoylation, elevated reactive oxygen species, impaired electron transport chain activity, fragile Fe-S clusters, and increased reliance on the tricarboxylic acid cycle-which collectively increase neuronal susceptibility to copper dyshomeostasis. Clarifying and understanding the critical roles of copper metabolism not only elucidates the pathogenesis of neurodegenerative diseases but also offers alternative therapeutic strategies. This review uniquely integrates the mitochondria-centered cuproptosis axis with copper dyshomeostasis across Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, and prion diseases, mapping convergent vulnerabilities to mechanism-grounded interventions and outlining testable translational routes.\n\nID: 42144443\nTitle: CCS facilitates the progression of ovarian cancer by suppressing ferroptotic cell death via the modulation of p53-mediated expression of SLC7A11 and GPX4.\nAbstract: Ovarian cancer is the most prevalent and deadly gynecological malignancy worldwide, with a 5-year overall survival rate of only 10%-40% for patients with advanced disease. Copper chaperone for superoxide dismutase 1 (CCS) is a metallochaperone that plays a multifaceted role in the maturation of copper and displays aberrant expression levels and functions in cancer. Ferroptosis, a new form of cell death resulting from iron-dependent lipid peroxidation, is closely related to cancer. However, whether CCS regulates ferroptosis in ovarian cancer is unknown, and its underlying mechanisms have not been reported. Here, we report that highly expressed CCS contributes to ovarian cancer tumor growth. Moreover, suppressing CCS induced ferroptosis in ovarian cancer cells and increased their sensitivity to ferroptosis inducers. Mechanistically, high CCS expression was found to reduce intracellular copper ion levels and increase Solute Carrier Family 7 Member 11 (SLC7A11) or Glutathione Peroxidase 4 (GPX4) expression by increasing p53 ubiquitination, thus affecting ferroptosis. Additionally, DC_AC50, a small-molecule inhibitor of CCS that targets its copper transport interface, regulates ferroptosis and ovarian cancer growth. Analysis of clinical data revealed a positive correlation between high CCS expression and high SLC7A11 and GPX4 expression in ovarian cancer patients. In summary, our study reveals that CCS protects ovarian cancer cells from ferroptosis by promoting SLC7A11 and GPX4 expression in a p53-dependent manner.\n\nID: 42103041\nTitle: Multimodal strategies for diagnosis, stratification, and therapeutic monitoring in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder of motor neurons (MN) that is currently diagnosed through a prolonged process of exclusion, often delaying intervention. This review provides an overview of fluid, imaging, electrophysiological, and genetic biomarkers, explicitly linking each modality to early detection, patient stratification, disease monitoring, therapeutic development, and clinical trial design. Fluid biomarkers (i.e., neurofilament light chain, phosphorylated neurofilament heavy chain, inflammatory cytokines, microRNAs, and proteins in blood or cerebrospinal fluid) reflect neuronal injury and/or disease activity, enabling early identification of pres-ymptomatic individuals and longitudinal tracking of neurodegeneration. Imaging biomarkers, such as structural and diffusion MRI of the motor cortex, corticospinal tracts, and spinal cord, as well as PET imaging neuroinflammation or metabolism, provide objective measures of MN degeneration and extra-motor involvement. Electrophysiological biomarkers, including high-density electromyography, motor unit number, transcranial magnetic stimulation, and electrical impedance myography, quantitatively assess upper and lower MN loss and functional reserve. Genetic biomarkers, encompassing variants in genes such as C9orf72, SOD1, FUS, and TARDBP, enable presymptomatic screening and molecular stratification. In this context, transposable elements have emerged as an additional layer linking genomic variation and RNA dysregulation. We highlight the importance of multimodal and stage-specific biomarker integration to improve diagnostic accuracy and illuminate distinct disease phases. This approach supports stratification by progression rate or molecular subtype, enrichment of clinical trial cohorts, and the development of surrogate endpoints. We conclude by discussing current challenges, including disease heterogeneity and assay standardization, and outline future directions toward biomarker-driven precision medicine in ALS.\n\nID: 42089121\nTitle: Targeted Gut Delivery of Zn, Cu, and Mn Nanominerals Alleviates Oxidative Stress by Activating Endogenous SOD Enzymes.\nAbstract: Trace minerals such as Zn, Cu, and Mn are essential for maintaining cellular redox balance as cofactors of key antioxidant enzymes, including SOD1 and SOD2. However, their oral supplementation is often limited by poor stability in the acidic gastric environment and low intestinal absorption. Here, we report the synthesis of methionine-coated-ZnO (Met-ZnO), ascorbic acid-coated Cu2O (AA-Cu2O), and dextran-coated MnO2 (Dex-MnO2) nanominerals, followed by encapsulation into pH-responsive microcapsules (NMs-MCap) for targeted intestinal delivery. The nanomineral mixture demonstrated strong antioxidant activity at physiological pH by scavenging superoxide radicals, hydrogen peroxide, and ABTS\u2022+ radicals. In intestinal epithelial (IEC-6)\u00a0cells, nanominerals significantly alleviated BSO-induced oxidative stress, reducing apoptosis, necrosis, and intracellular ROS accumulation. Oral administration of NMs-MCap in Zn, Cu, and Mn-deficient rats elevated mineral levels in blood and liver, mitigated BSO-induced oxidative damage, reduced lipid peroxidation and pro-inflammatory cytokines, and preserved tissue architecture. Importantly, oral supplementation restored SOD1 and SOD2 expression in key organs, supporting enhanced endogenous antioxidant defense. Metagenomic analysis revealed that mineral deficiency, combined with oxidative stress, caused gut dysbiosis, reducing beneficial taxa and enriching opportunistic ones. Nanomineral supplementation restored microbial balance, increased SCFA-producing bacteria, and improved antioxidant and metal-handling functions, establishing NMs-MCap as a safe, targeted antioxidant strategy supporting host health.\n\nID: 42080225\nTitle: Identification of Hoiamide A as an Inducer of Oxidative and Endoplasmic Reticulum Secretory Pathway Stress.\nAbstract: The endoplasmic reticulum (ER) to Golgi secretory compartment of eukaryotic cells is highly sensitive to changes in intracellular homeostasis. Using a primary screening assay that monitors the function of this pathway, we prioritized a cyanobacterial extract from the Red Sea that decreased secretion of a bioluminescent reporter, Gaussia luciferase (GLuc), in living cells. A comparison of LCMS2 data against the GNPS database revealed a match for macrocyclic depsipeptide hoiamide A (1). Biological testing confirmed the ability of 1 to induce a mixed, non-lethal stress response in human U87-MG glioblastoma cells; analysis of stress markers by qRT-PCR revealed early upregulation of superoxide dismutase 1 (SOD1) and C/EBP-homologous protein (CHOP) relative to the control. Co-treatment of cells with 1 (100 nM to 3 \u03bcM) and antioxidant N-acetylcysteine afforded full protection from 1-induced decreases in GLuc secretion. We report that terminally differentiated human SH-SY5Y neuroblastoma cells, with a neuron-like phenotype, are highly sensitive to nanomolar concentrations of 1, whereas undifferentiated cells remained viable at 3 \u03bcM. These results expand the known biology of hoiamides and suggest that neurotoxic potential of 1 is likely due to an inherent failure of neurons to adapt to the loss of redox homeostasis and sustained ER stress.\n\nID: 42076719\nTitle: Look Trout in the Eye: Corneal Biomarkers of Ammonia Stress in Recirculating Aquaculture Systems Treated with TiO2 Photoelectrocatalysis.\nAbstract: The eye is a sensitive target of sublethal stress in aquaculture-reared fish due to its direct exposure to the aquatic environment. This study tested a photoelectrocatalytic (PEC) water treatment system, integrated into a standard recirculating aquaculture system (RAS), to improve water quality and evaluated ocular health in Oncorhynchus mykiss (rainbow trout) reared at 30 kg/m3 for 28 days, with particular emphasis on the cornea as an indicator of fish welfare. Ocular analyses focused on the cornea and retina, two anatomically and functionally distinct structures. PEC significantly reduced ammonia levels and modulated nitrate concentrations compared to the control group (CTR), represented by a standard RAS. No differences in growth performance or body condition were observed between groups. Corneal integrity was assessed using optical coherence tomography, histology, and mucous cell staining to evaluate epithelial structure and protective responses. Corneal tissue was examined to detect local oxidative effects through morphological analysis and immunohistochemistry for 8-hydroxy-2'-deoxyguanosine (8-OHdG). Alcian Blu-Periodic Acid-Schiff (AB-PAS) staining did not reveal significant differences in mucin-producing cells among groups. CTR fish exhibited epithelial disruption and increased 8-OHdG immunoreactivity, whereas fish reared in the RAS equipped with the PEC system, ensuring improved water quality, showed preserved corneal architecture despite mild oxidative stress. Molecular analysis of ocular tissues revealed no differential expression of oxidative stress-related genes, such as GPx1, GR, or sod1, in the two groups. Overall, these findings support the use of the cornea as a sensitive indicator of sublethal environmental stress in farmed fish and suggest that PEC treatment may contribute to improved water quality management and welfare monitoring in intensive aquaculture systems.\n\nID: 42074537\nTitle: Gene Targeted Therapies for Neurodegenerative Disorders: Strategies and Implications in ALS and SMA.\nAbstract: Advances in technology have provided a better understanding of the genetic basis of neurodegenerative disorders and their underlying molecular pathophysiology. However, treating these disorders with conventional strategies is a major challenge. The approval of gene targeted therapy for spinal muscular atrophy (SMA) has laid the foundation for developing highly personalized therapies for other neurodegenerative disorders. As intensive research and efforts to advance gene targeted therapies continue, this review provides an overview of viral and non-viral vectors and delivery methods, as well as treatment strategies, including gene addition, replacement, editing, silencing, and splice modulation. Gene targeted approaches and clinical trials for SMA and amyotrophic lateral sclerosis (ALS) have demonstrated success, and additional studies are in progress. The design of efficient clinical trials which facilitate successful translation into clinical practice is of critical importance. Key considerations include the selection of appropriate disease models, understanding the natural history of the disease, and establishing well-defined outcome measures to assess prognosis of the disease and therapeutic efficacy. Finally, the precision of CRISPR-based gene editing offers the potential for one-time corrective therapies for monogenic disorders like SMA and SOD1-ALS.\n\nID: 42051098\nTitle: Zebrafish (Danio rerio) as a Model for Neurodegenerative Disease Research: Mechanisms, Biomarkers, and Translational Promise.\nAbstract: Zebrafish (Danio rerio) have gained prominence as a versatile vertebrate model for studying neurodegenerative disorders due to their genetic similarity to humans, rapid development, transparency, and suitability for high-throughput drug screening. The usefulness of zebrafish in modelling human neurological disorders is supported by the similarity of their brains' anatomical and neurochemical characteristics, including comparable divisions of the forebrain, midbrain, and hindbrain, as well as dopaminergic, serotonergic, glutamatergic, and GABAergic pathways. Zebrafish have been used to successfully model several neurodegenerative diseases, including Alzheimer's disease (via tau phosphorylation and amyloid-beta aggregation), Parkinson's disease (via dopaminergic neuronal loss and alpha-synuclein pathology), Huntington's disease (via polyglutamine-expanded huntingtin), and amyotrophic lateral sclerosis (via mutant SOD1 and TDP- 43 transgenes). They have also been used to study multiple sclerosis, spinocerebellar ataxias, and Rett syndrome, enabling mechanistic exploration and preclinical drug discovery. This review crucially depicts how zebrafish models provide an affordable, morally acceptable, and scalable platform for early-stage neurodegeneration research. These models complement, rather than replace, rodent- and human-derived systems. Additionally, we will review how to bridge the gap between therapeutic screening and basic mechanistic findings, highlighting their increasing significance in the neuroscience research continuum.\n\nID: 42042930\nTitle: Aerobic Exercise Alleviates Oxidative Stress and Inflammation to Attenuate High-Fat Diet-Induced Non-Alcoholic Fatty Liver Disease in ApoE-/- Mice.\nAbstract: Background/Objectives: The development of non-alcoholic fatty liver disease (NAFLD) is closely linked to oxidative stress and inflammation. Aerobic exercise has been shown to improve NAFLD, although its underlying mechanisms remain incompletely understood. This study utilized ApoE-/- mice to investigate the role of Sestrin2 in aerobic exercise-induced amelioration of NAFLD. Methods: Random assignment of C57BL/6J and ApoE-/- mice yielded four groups: C (control), CE (aerobic exercise), AS (ApoE-/- control), and AE (ApoE-/- aerobic exercise). Aerobic exercise lasting 12 weeks was administered to the CE and AE groups. Serum biomarkers were analyzed by ELISA, liver tissue morphology was assessed via HE and ORO staining, and macrophage polarization was evaluated through immunofluorescence. Additionally, mRNA and protein expression levels were measured by qPCR and Western blot. Results: Aerobic exercise reduced liver wet weight, lipid accumulation, and steatosis in ApoE-/- mice. Aerobic exercise attenuates hepatic oxidative stress, and upregulated the expression of regulation oxidative stress related gene and proteins of Nrf2, HO-1, CAT, and SOD1 in ApoE-/- mice. Aerobic exercise promoted a shift in macrophage polarization from the pro-inflammatory M1 phenotype toward the anti-inflammatory M2 phenotype in the liver, and significantly reduced TNF-\u03b1 and IL-1\u03b2 levels, accompanied by upregulation of Sestrin2 expression, enhanced AMPK phosphorylation, inhibited mTORC1 in the liver. Conclusions: These findings suggest that aerobic exercise alleviates oxidative stress and inflammation in NAFLD, with Sestrin2 activation playing a central role.\n\nID: 42019875\nTitle: Sex and age influence antioxidant gene expression and oxidative stress markers in the mouse cornea.\nAbstract: To determine age- and sex-related differences in antioxidant genes and oxidative stress in the mouse cornea. Eyes from 6-8-week- and 9-month-old male and female C57BL/6J wild-type (WT) and xCT knockout (KO) mice -a model of accelerated aging-were examined with the Micron IV slit lamp, OCT attachments and iCare\u00ae TONOLAB. Droplet digital PCR was carried out to measure antioxidant genes SOD1, CAT, GPX1, GPX4, PRDX6, TXNRD1, GCLC, and GSR in WT and xCT KO corneas. Immunohistochemistry was used to visualise oxidative stress markers 4-Hydroxynonenal and 8-Hydroxydeoxyguanosine in the different layers of the WT and xCT KO corneas. WT and xCT KO corneas were transparent with age, with both showing an age-related decrease in IOP. Sex-dependent differences were seen in antioxidant genes between WT and xCT KO corneas. Male xCT KO corneas showed increased CAT, GPX1 and GPX4 at 6-8-weeks relative to WT. xCT KO corneas revealed increased GPX1 in both sexes at 9 months of age while female 9-month-old xCT KO corneas showed increased GPX4 compared to WT. TXNRD and GCLC was reduced in 6-8-week-old female xCT KO corneas. 4-HNE levels were unchanged, but 8-OhDG was elevated in xCT KO corneas across ages and sexes, especially in males and notably in the endothelium. This study reveals age and sex dependent differences in the expression of antioxidant defence genes and oxidative stress markers in the mouse cornea highlighting the importance of biological sex when studying corneal diseases that involve oxidative stress as an underlying mechanism.\n\nID: 42008072\nTitle: A novel 14-deoxy-12-hydroxyandrographolide analogue promotes apoptosis in colorectal cancer through ROS-dependent endoplasmic reticulum stress activation.\nAbstract: Colorectal cancer is the second leading cause of cancer-related mortality worldwide, highlighting the critical need for novel therapeutic strategies. In this study, we investigated the anticancer activity and molecular mechanisms of RS-PP-059, a derivative of 14-deoxy-12-hydroxyandrographolide, in colorectal cancer cells. RS-PP-059 exhibited potent cytotoxicity and selectivity toward HT-29 cells, suppressing viability and clonogenic growth. The compound induced apoptotic cell death, as shown by increased Annexin V-positive cells, PARP-1 cleavage, p53 activation, and \u03b3-H2AX accumulation, indicating DNA damage, and was accompanied by a reduction in total caspase-3 protein levels. Mechanistically, RS-PP-059 triggered endoplasmic reticulum (ER) stress and unfolded protein response (UPR), upregulating key markers including GRP78, IRE1\u03b1, CHOP, and spliced XBP1 (XBP1s) at both mRNA and protein levels. Co-treatment with the ER stress inhibitor 4-phenylbutyrate (4-PBA) only partially reversed these effects, suggesting robust ER stress activation by RS-PP-059. In parallel, RS-PP-059 increased intracellular reactive oxygen species (ROS) in a time-dependent manner, accompanied by differential regulation of antioxidant genes with strong induction of HO-1 and suppression of CAT, SOD1, and GPX-1. Importantly, pretreatment with N-acetyl-L-cysteine (NAC) abolished ROS accumulation, ER stress activation, apoptosis, and loss of viability, confirming the ROS-dependent mechanism. In conclusion, our findings demonstrate that RS-PP-059 exerts potent anticancer effects in colorectal cancer cells by promoting ROS-mediated ER stress, leading to DNA damage and apoptosis.\n\nID: 42003610\nTitle: Met32 governs transcriptional control of sulfur metabolic flexibility and resistance to reactive sulfur species in the human fungal pathogen Candida albicans.\nAbstract: Although considerable advances have been made in understanding the metabolic machinery that enables bacteria to utilize sulfur sources, our understanding of the corresponding processes in fungi remains comparatively fragmentary. To explore the genetic circuit by which the highly prevalent human opportunistic yeast Candida albicans controls sulfur utilization, we characterized the transcriptional landscape associated with sulfur starvation in this fungus. We identified many desulfonation enzymes that were differentially modulated and showed that Jlp12, a sulfonate/\u03b1-ketoglutarate dioxygenase, was critical for the utilization of different sulfur sources found in many niches of the human host. We also uncovered that the zinc-finger transcription factor Met32 acts as a master regulator, modulating genes involved in sulfur utilization, including Jlp12. Importantly, we found that C. albicans Met32 exclusively regulates sulfur utilization genes, while in the Saccharomyces cerevisiae lineage, it controls methionine biosynthesis. This work also identified Seo13 as the first major facilitator superfamily transporter in fungi to transport the alternative sulfur source glutathione, under the direct control of Met32. Furthermore, we showed that Met32 modulates C. albicans tolerance to sulfite excess by tuning the basal transcriptional level of the superoxide dismutase Sod1. This underscores the dual role of Met32 in the breakdown of sulfur-containing metabolites and the neutralization of the resulting reactive sulfur species (RSS). Our study delineates a new mechanism by which fungal pathogens utilize sulfur sources and neutralize RSS and underscores its importance in fungal fitness in vivo. Candida albicans is the most prevalent fungal colonizer of humans, and it is also the first cause of disseminated fungal infections leading to a high mortality rate. The ability of this yeast to metabolize a plethora of carbon and nitrogen sources inside the host is a critical asset for both the commensal and the pathogenic lifestyles of this yeast. Thus, these pathways represent attractive targets for antifungal therapy. While sulfur is an essential nutritional element for all living organisms, its contribution to fungal virulence remains understudied. Here, we describe new players of sulfur utilization metabolism in C. albicans and underline their importance in supporting fungal virulence. This work emphasizes the significance of targeting sulfur metabolic flexibility to manage fungal infections.\n\nID: 42480869\nTitle: Macrophage responses to and elevated antibody levels against Chlorovirus ATCV-1 in ALS patients.\nAbstract: Acanthocystis turfacea chlorella virus 1 (ATCV-1) is a giant virus that is part of the human oral microvirome. Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease.\n\nID: 42453524\nTitle: Therapeutic potential of adipose-derived stem cell transplantation in amyotrophic lateral sclerosis: A combined clinical case and preclinical study.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an inevitably fatal neurodegenerative disease with no adequate treatment. Transplantation of adipose-derived stem cells (ADSCs) may be an effective therapeutic strategy for delaying progression or restoring neurological function in ALS. We evaluated the safety and therapeutic efficacy of intravenous (i.v.) and intracerebral (i.c.) ADSC injection in a late-stage ALS patient and in a SOD1 transgenic (Tg) mouse model. Magnetic resonance imaging (MRI) and computed tomography (CT) were conducted to examine potential cerebral hemorrhage and tumor generation in the treated patient. In addition, maximal inspiratory pressure, maximal expiratory pressure, tidal volume, and respiratory rate were measured as indices of respiratory function. ADSC transplantation was safe, with MRI and CT showing no hemorrhage or tumorigenesis up to 12 months. The patient's Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score improved from 7 to 9 at 3 months and remained above baseline for 6 months. Respiratory function was preserved during this period. In SOD1 Tg mice, i.c. and i.v. ADSC infusion significantly prolonged survival (165.0 \u00b1 10.4 and 147.3 \u00b1 4.5 days vs. 129.7 \u00b1 3.9 days) and improved motor scores (P < 0.01). This preliminary finding suggests potential therapeutic feasibility, but further studies with larger cohorts are needed to confirm its safety and efficacy.\n\nID: 42406382\nTitle: Antisense Oligonucleotide Tofersen Distribution in the Central Nervous System of SOD1-ALS Autopsy Tissue Donors.\nAbstract: Tofersen is a disease-modifying antisense oligonucleotide therapeutic for people living with SOD1-amyotrophic lateral sclerosis (SOD1-ALS). Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues.\n\nID: 42353187\nTitle: Overexpression of Stanniocalcin 2 Protects Differentiated QM7 Cells from H2O2-Induced Oxidative Damage.\nAbstract: Oxidative stress, caused by excessive reactive oxygen species (ROS) accumulation, is a major factor in muscle cell damage and muscle atrophy-related disorders. Although Stanniocalcin 2 (STC2) is involved in cellular stress and exhibits cytoprotective effects in various cell types, its role in skeletal muscle cells during oxidative stress is unclear. This study investigated the effects of STC2 overexpression in quail muscle (QM7) cells exposed to H2O2-induced oxidative stress. STC2 expression was upregulated in non-transfected QM7 cells following H2O2 treatment. Stable STC2-overexpressing cells were differentiated for 4 days, and then assessed for cell viability, ROS accumulation, cell death, and myotube morphology following H2O2 treatment. Compared with control cells, STC2-overexpressing cells exhibited higher cell viability, reduced ROS accumulation, and decreased cell death. STC2 overexpression also attenuated the H2O2-induced reduction in MyHC protein expression. Antioxidant-related genes, including Superoxide Dismutase 1, Glutathione Peroxidase 1, Heme Oxygenase 1, and NAD(P)H Quinone Dehydrogenase 1, were significantly upregulated in STC2-overexpressing cells. Compared with the control cells, nuclear factor erythroid 2-related factor 2 protein levels were not increased in STC2-overexpressing cells under oxidative stress conditions. These findings suggest that STC2 overexpression alleviates oxidative stress-induced cellular damage and may contribute to protective antioxidant responses in muscle cells.\n\nID: 42352067\nTitle: Urate as a CO3\u2022- Scavenger and Regulator of SOD-1 and OGG1 Enzymes: Insights from DFT, Molecular Docking, and Molecular Dynamics.\nAbstract: The potency of urate, an abundant human plasma antioxidant, in preventing oxidative damage caused by the carbonate radical anion CO3\u2022-, was studied using quantum chemical calculations. The influence of microhydration of CO3\u2022-/CO32- and urate-/urate\u2022 couples on the thermodynamic and kinetics of the one-electron oxidation process was investigated. Depending on the degree of microhydration, the estimated rate constant for one-electron transfer is in the range of 2.0-7.3 \u00d7 109 M-1 s-1, in good agreement with the experimental value of 1.3 \u00d7 109 M-1 s-1. Modeling using vertical detachment energy and electron affinity, the driving forces of single electron transfer revealed urate(H2O)6- and CO3(H2O)9\u2022- clusters as the most likely existing species in water. Molecular docking revealed a favorable interaction of urate with the catalytic pocket of SOD1. Urate binds more strongly to the anionic active center of SOD1 than the reference inhibitor LSC-1, indicating its potency to prevent HCO3--supported CO3\u2022- formation. In contrast, the known OGG1 inhibitor TH13264 shows substantially stronger binding than urate, indicating urate's weaker affinity toward the DNA repair enzyme catalytic pocket. The molecular dynamics data indicate that urate binding does not destabilize either SOD1 or OGG1. In light of increasing evidence that the major source of oxidative stress could be CO3\u2022-, rather than the commonly assumed hydroxyl radical HO\u2022, the obtained results indicate the inherent ability of plasma to combat oxidative stress induced by this selective, milder oxidant. Such an ability with respect to the non-selective, highly reactive HO\u2022 does not exist in vivo.\n\nID: 42352031\nTitle: Statin-Induced Coenzyme Q Deficiency Induces Metabolic Reprogramming in Astrocytes.\nAbstract: Statins are commonly used cholesterol-lowering drugs, but their effects on astrocyte oxidative metabolism are poorly understood. To investigate this, rat astrocytes were exposed to 200 nM atorvastatin or simvastatin for 6 days and then assessed for changes in coenzyme Q (CoQ) homeostasis, mitochondrial function, and energy metabolism. Both statins comparably decreased cellular CoQ9 and CoQ10 levels (~35%), with greater losses of their reduced antioxidant forms (60-75%). Lower intracellular and mitochondrial levels of reactive oxygen species (ROS) were accompanied by the upregulation of nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant pathways (superoxide dismutase 1 and glutathione reductase) and metabolic stress response factors, including hypoxia-inducible factor 1-alpha (HIF1\u03b1) and brain-derived neurotrophic factor (BDNF). Both statins promoted glycolytic reprogramming, mitochondrial fission, and biogenesis while impairing oxidative phosphorylation, as evidenced by reduced ATP-linked respiration, increased proton leak, and lower ATP levels. These findings suggest that statin-treated astrocytes adapt by prioritizing redox homeostasis over ATP production. CoQ10 supplementation increased cellular CoQ10 levels and restored ATP levels without further decreasing ROS, suggesting that its primary benefit is bioenergetic support, not additional antioxidant protection. Overall, statin-induced CoQ deficiency induces adaptive metabolic remodeling of astrocytes, while CoQ10 supplementation may help maintain energy metabolism under these conditions.\n\nID: 42351996\nTitle: Metabolic Responses of Melanocytes and Melanoma Cells to UVA Radiation and Phytocannabinoids Exposure.\nAbstract: Ultraviolet A (UVA) radiation disrupts the redox balance of melanocytes and may lead to the development of melanoma, highlighting the need for new skin protection strategies. This study assessed the effect of phytocannabinoids [cannabigerol (CBG), cannabidiol (CBD), and CBG + CBD] on redox homeostasis in control and UVA-exposed melanocytes and in melanoma cells (SK-Mel-5). UVA radiation increased the activity of prooxidant enzymes in both melanocytes and SK-Mel-5 cells and, consequently, the level of reactive oxygen species (ROS) (approx. 2-fold). It also activated nuclear factor erythroid 2 (Nrf2), as reflected by increased expression of heme oxygenase 1 (HO-1) (melanocytes approx. 2-fold; SK-Mel-5 approx. 7-fold). Concomitantly, antioxidant mechanisms were impaired, as demonstrated by reduced superoxide dismutase (SOD1/SOD2) activity and impaired glutathione and thioredoxin function. These changes were accompanied by increased levels of oxidative damage markers (isoprostanes, 4-hydroxynonenal-4-HNE, and 4-HNE-protein adducts) (43-100%) and increased inflammatory signaling, including increased expression of nuclear factor kappa B (NF-\u03baB) subunits (melanocytes: p52 ~2-fold, p65 ~75%; SK-Mel-5: ~4-4.5-fold) and tumor necrosis factor alpha (TNF-\u03b1; ~30%). Phytocannabinoid treatment modulated these UVA-induced changes. In SK-Mel-5 cells, phytocannabinoids normalized the activity of prooxidant enzymes and consequently reduced ROS levels (~30%). They also reduced Nrf2 activation and HO-1 expression; however, CBG increased HO-1 level in melanocytes (~25-40%). Furthermore, phytocannabinoids enhanced antioxidant defense by increasing SOD activity, particularly in melanocytes (~10-40%), and restoring the glutathione and thioredoxin systems. Markers of oxidative damage were reduced by approximately 23-37% after treatment. Furthermore, phytocannabinoids attenuated NF-\u03baB activation (p52 ~18-28%, p65 ~25-29% in melanocytes; ~20% in SK-Mel-5), while TNF-\u03b1 levels remained unchanged. The effects in non-irradiated cells were modest (<15%). These results suggest that phytocannabinoid-mediated modulation of redox balance may stabilize melanocytes exposed to UVA radiation and potentially reduce the risk of neoplastic transformation. However, the observed protective effects in SK-Mel-5 cells require further investigation and detailed molecular analysis.\n\nID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.\n\nID: 42343520\nTitle: [Effect of electroacupuncture at \"Zusanli\" (ST36) on TREM2-mediated microglial activation in amyotrophic lateral sclerosis mice].\nAbstract: To observe the effect of electroacupuncture (EA) at \"Zusanli\" (ST36) on amyotrophic lateral sclerosis (ALS) in mouse models based on myeloid cell trigger receptor 2 (TREM2)-mediated microglial activation. Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1\u03b2, \u03b3 interferon (IFN-\u03b3), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1\u03b2, IFN-\u03b3, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1\u03b2 and IFN-\u03b3 decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1\u03b2,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05). Electroacupuncture at \"Zusanli\" (ST36) exhibits a certain improvements in motor function of SOD1-G93A transgenic mice. The underlying mechanism may be related to attenuating neuroinflammation via the modulation of microglial activation mediated by TREM2. \u76ee\u7684\uff1a\u57fa\u4e8e\u9ad3\u6837\u7ec6\u80de\u89e6\u53d1\u53d7\u4f532\uff08TREM2\uff09\u4ecb\u5bfc\u7684\u5c0f\u80f6\u8d28\u7ec6\u80de\u6d3b\u5316\u89c2\u5bdf\u7535\u9488\u201c\u8db3\u4e09\u91cc\u201d\u5bf9\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\u75c7\u6a21\u578b\u5c0f\u9f20\u795e\u7ecf\u708e\u75c7\u7684\u5f71\u54cd\u3002 \u65b9\u6cd5\uff1a\u5c0636\u53eaSPF\u7ea7\u96c4\u6027\u4eba\u7a81\u53d8\u578b\u8d85\u6c27\u5316\u7269\u6b67\u5316\u91761\uff08SOD1-G93A\uff09\u8f6c\u57fa\u56e0\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u6a21\u578b\u7ec4\u3001\u7535\u9488\u7ec4\u3001\u836f\u7269\u7ec4\uff0c\u6bcf\u7ec412\u53ea\uff1b\u9009\u53d612\u53ea\u540c\u7a9d\u91ce\u751f\u5c0f\u9f20\u4f5c\u4e3a\u5bf9\u7167\u7ec4\u3002\u7535\u9488\u7ec4\u4e8e\u201c\u8db3\u4e09\u91cc\u201d\u8fdb\u884c\u7535\u9488\u5e72\u9884\uff0c\u91c7\u7528\u65ad\u7eed\u6ce2\uff0c\u9891\u738715 Hz\uff0c\u6bcf\u6b2110 min\uff0c\u9694\u65e51\u6b21\uff0c\u6bcf\u54683\u6b21\uff0c\u51714\u5468\uff1b\u836f\u7269\u7ec4\u4e88\u5229\u9c81\u5511\u6eb6\u6db2\uff088 mg/kg\uff09\u704c\u80c3\uff0c\u6bcf\u65e51\u6b21\uff0c\u51714\u5468\u3002\u5e72\u9884\u7ed3\u675f\u540e\uff0c\u5e94\u7528\u8f6c\u68d2\u6d4b\u8bd5\u4e0e\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u8bc4\u4f30\u5404\u7ec4\u5c0f\u9f20\u884c\u4e3a\u5b66\uff0cHE\u67d3\u8272\u548c\u5c3c\u6c0f\u67d3\u8272\u89c2\u5bdf\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u5f62\u6001\uff0c\u514d\u75ab\u8367\u5149\u6cd5\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\uff0cWestern blot\u6cd5\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u7ec4\u7ec7\u767d\u7ec6\u80de\u4ecb\u7d20\uff08IL\uff09-1\u03b2\u3001\u03b3\u5e72\u6270\u7d20\uff08IFN-\u03b3\uff09\u3001IL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u7ec4\u7ec7\u5355\u7ec6\u80de\u60ac\u6db2CD86+\u548cCD206+\u7ec6\u80de\u6bd4\u4f8b\u3002 \u7ed3\u679c\uff1a\u4e0e\u5bf9\u7167\u7ec4\u6bd4\u8f83\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u6392\u5217\u7d0a\u4e71\uff0c\u51fa\u73b0\u6838\u56fa\u7f29\u3001\u80de\u4f53\u76b1\u7f29\u7b49\u73b0\u8c61\uff1b\u8f6c\u68d2\u6d4b\u8bd5\u6f5c\u4f0f\u671f\u548c\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u6389\u843d\u65f6\u95f4\u7f29\u77ed\uff0c\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u3001IFN-\u03b3\u3001IL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5355\u7ec6\u80de\u60ac\u6db2CD86+\u3001CD206+\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u6bd4\u8f83\uff0c\u7535\u9488\u7ec4\u548c\u836f\u7269\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u6392\u5217\u8f83\u89c4\u6574\uff0c\u6838\u56fa\u7f29\u53ca\u5c3c\u6c0f\u5c0f\u4f53\u6eb6\u89e3\u4e22\u5931\u73b0\u8c61\u6539\u5584\uff0c\u795e\u7ecf\u5143\u7ed3\u6784\u5b8c\u6574\u6027\u63d0\u9ad8\uff1b\u8f6c\u68d2\u6d4b\u8bd5\u6f5c\u4f0f\u671f\u548c\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u6389\u843d\u65f6\u95f4\u5ef6\u957f\uff0c\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\u964d\u4f4e\uff0c\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u3001IFN-\u03b3\u86cb\u767d\u8868\u8fbe\u964d\u4f4e\uff0cIL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7CD86+\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e\uff0cCD206+\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8\uff08P<0.01\uff0cP<0.05\uff09\u3002\u4e0e\u836f\u7269\u7ec4\u6bd4\u8f83\uff0c\u7535\u9488\u7ec4\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0cIL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u964d\u4f4e\uff0cCD206+\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e\uff08P<0.05\uff09\u3002 \u7ed3\u8bba\uff1a\u7535\u9488\u201c\u8db3\u4e09\u91cc\u201d\u5bf9SOD1-G93A\u8f6c\u57fa\u56e0\u5c0f\u9f20\u8fd0\u52a8\u529f\u80fd\u5177\u6709\u4e00\u5b9a\u7684\u6539\u5584\u4f5c\u7528\uff0c\u5176\u4f5c\u7528\u673a\u5236\u53ef\u80fd\u4e3a\u8c03\u63a7TREM2\u4ecb\u5bfc\u7684\u5c0f\u80f6\u8d28\u7ec6\u80de\u6d3b\u5316\uff0c\u8fdb\u800c\u6539\u5584\u795e\u7ecf\u708e\u75c7\u3002.\n\nID: 42343420\nTitle: Immune checkpoint LAG-3 governs stage-dependent and disease-associated microglial modules in ALS model mice.\nAbstract: Immune checkpoint molecules, inhibitory receptors originally characterized in T cell biology, have recently emerged as regulators of microglial function in neurodegeneration, yet their roles in amyotrophic lateral sclerosis (ALS) remain unexplored. Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration.\n\nID: 42328125\nTitle: Polyinosinic:polycytidylic acid causes epithelial-mesenchymal transition via BAFF expression in Beas-2B human bronchial epithelial cells.\nAbstract: The bronchial epithelium acts not only as the primary physical barrier but also as an active sensor that responds to exogenous materials such as bacteria and viruses, by producing various cytokines including B-cell activating factor (BAFF). Although BAFF is a well-known protein in B-cell functions, its role in bronchial cell function remains undefined. Polyinosinic-polycytidylic acid (Poly (I:C)), a synthetic double-stranded RNA, serves as a model for viral infection that binds to toll-like receptor (TLR) 3 to trigger intracellular signal pathways. In this study, we investigated the effect of Poly (I:C)-induced BAFF expression on airway cell migration using Beas-2B human bronchial epithelial cells. Poly (I:C) increased BAFF expression and cell migration, along with the increased expression of N-cadherin, Vimentin and Slug (SNAI2), which are three primary markers for epithelial-mesenchymal transition (EMT). Cell migration was attenuated by small interfering RNA (siRNA) against BAFF, which also inhibited the expression of these EMT markers. Phosphorylation of c-Jun N-terminal kinase (JNK) was enhanced by Poly (I:C) and inhibited by SP600125, JNK inhibitor, leading to a decreased expression of BAFF and aforementioned EMT markers. Poly (I:C) increased reactive oxygen species (ROS), resulting in a ROS-dependent up-regulation of antioxidants (Catalase, superoxide dismutase (SOD)1 and heme oxygenase (HMOX)1) and Nrf2. Pre-treatment with N-acetylcysteine (NAC), ROS scavenger, inhibited Nrf2 activation and JNK phosphorylation. The increase in Nrf2 levels induced by Poly (I:C) was also attenuated by SP600125. Additionally, while NAC treatment inhibited BAFF expression, it caused little change in the expression of the three EMT markers. Increased BAFF expression was confirmed by Nrf2 binding to the BAFF promoter or an increase in the luciferase activity of BAFF promoter co-transfected with Nrf2 plasmids. Treatment with recombinant BAFF protein also increased cell migration and EMT marker expression. Taken together, our results demonstrate that Poly (I:C) promotes a regenerative migration of bronchial epithelial cells by inducing BAFF expression through the ROS-dependent JNK-Nrf2 signaling axis.\n\nID: 42313275\nTitle: Immune response in honey bees (Apis mellifera) following humic substance feeding.\nAbstract: Humic substances (HS) are increasingly investigated as natural additives to support health in humans and animals, yet their effects on honey bees remain insufficiently characterised. This study evaluated the impact of a commercial HS-based product on immunity and oxidative status of Apis mellifera. Newly emerged worker bees were kept under laboratory conditions and fed sugar syrup supplemented with 0.5% HS for seven days, while the control group received unsupplemented syrup. Effects of HS were evaluated by analysing the expression of selected immune-related genes, quantifying antimicrobial peptides (AMPs), measuring the activity of antioxidant enzymes, evaluating lipid peroxidation, and characterising hemocyte populations. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. Similarly, catalase enzymatic activity was significantly decreased in the HS group. No significant changes were detected in gene expression for other AMPs and relative abundance of AMPs, or other antioxidant parameters. HS supplementation significantly increased the proportion of medium granular hemocytes (p\u2009<\u20090.05) at the expense of high granular cells (p\u2009<\u20090.01). In conclusion, the 7-day administration of HS at 0.5% did not adversely affect bee health and modulated selected immune parameters. The biological significance of these immunomodulatory effects requires confirmation through challenge studies and field trials under natural conditions.\n\nID: 42286839\nTitle: Optimizing Research Operations and Resource Utilization in ALS Care: Insights From the Tofersen Antisense Oligonucleotide Expanded Access Protocol.\nAbstract: Tofersen is a gene-targeted therapy for individuals with superoxide dismutase 1 (SOD1) (+) amyotrophic lateral sclerosis (ALS). Prior to U.S. Food and Drug Administration (FDA) approval, tofersen was made available through expanded access protocol. This study describes the clinical and operational experience of administering tofersen through expanded access protocols at a single academic medical center in the U.S. Individuals with symptomatic SOD1(+) ALS (\u2265\u200918\u2009years), who were ineligible for traditional ALS clinical trials, received tofersen via bedside lumbar punctures at Massachusetts General Hospital. Treatment was provided through single-patient and intermediate-sized expanded access protocols prior to FDA approval. Demographic and clinical characteristics, referral-to-treatment timelines, safety outcomes, and operational costs were collected. Eleven individuals with SOD1(+) ALS received monthly intrathecal tofersen over a two-year period (July 2021 to July 2023). Most participants were female, and 81.8% had leg-onset ALS. The mean (SD) referral-to-first dose duration was 36 (22.4) days. A total of 120 doses were administered over a two-year period. Tofersen was safe and well tolerated, with no treatment-related serious adverse events. Operational costs totaled $336,620, supported by philanthropy and insurance. The company provided the drug for free. This experience demonstrates the feasibility of implementing a resource-intensive expanded access protocol within an academic medical center using a mixed funding model to facilitate early access to emerging ALS therapies.\n\nID: 42282797\nTitle: PAD2 knockout reduces myelin protein aggregates, modulates neuroinflammation and protects motor neurons, axons and neuromuscular junction in a SOD1-ALS mouse model.\nAbstract: Dysregulated peptidyl deiminase 2 (PAD2) and aberrant protein citrullination (PC), a posttranslational modification (PTM), are involved in various inflammatory and neurodegenerative diseases. We previously showed in transgenic mice and postmortem human tissues that PC and PAD2 are altered in amyotrophic lateral sclerosis (ALS), a neurodegenerative disease characterized by motor neurons loss, paralysis, and death. Herein, we investigated the role of PAD2 in ALS by PAD2 knockout in a SOD1-ALS mouse model. To investigate the role of PAD2-induced citrullination in ALS pathogenesis, we generated PAD2 knockout (PAD2KO) in SOD1 G93A ALS mouse model and investigated the consequent modulation on the neuropathology and clinical symptoms, using molecular biology techniques such as qPCR, Western blotting, confocal microscopy, and electron microscopy. Additionally, we identified C3 as being citrullinated in human ALS using ionFinder. Our results show that PAD2KO blocked the increased PC and reduced myelin basic protein (MBP) aggregates in the ALS model. PAD2KO also improved motor neuron survival and the integrity of myelin, axons, and neuromuscular junctions, and reduced microgliosis in the white matter and C3 protein levels in astrocytes. Clinically, data from monitoring the body weight changes suggests that PAD2KO modulates the course of the disease in the ALS mouse model, accelerating the onset while slowing the progression after the onset, and modestly extending the survival of male mice. These results show that PAD2 is responsible for the increased PC in ALS and PC contributes to neuroinflammation and degeneration of motor neurons and myelinated axons. The modest modulation of the disease phenotype suggests that the role of PC in ALS is complex, involving altered PC in numerous proteins and in multiple cell types. Future studies are needed to investigate how PC modulates individual protein functions in various cell types to understand the contribution of PC to ALS pathogenesis.\n\nID: 42268341\nTitle: Pathogen-mediated priming induces intergenerational immunity against spot blotch in wheat.\nAbstract: Spot blotch, caused by Bipolaris sorokiniana, is one of the most destructive diseases of wheat (Triticum aestivum), particularly in warm and humid regions where yield losses may exceed 30-50%. Heavy dependence on fungicides is neither sustainable nor environmentally safe, creating an urgent need for innovative strategies to enhance crop resilience. Defense priming, a phenomenon in which prior exposure to a mild stimulus enables plants to mount faster and stronger defenses upon subsequent stress offers a promising alternative. Pathogens or pathogen-derived molecules such as PAMPs and effectors are known to serve as effective priming stimuli in plants. In this study, we hypothesized that attenuated spores of B. sorokiniana could act as a priming stimulus to enhance resistance against spot blotch in wheat. By applying a low-dose spore suspension, we sought to establish pathogen-mediated priming as a green vaccination strategy, wherein controlled pre-exposure to attenuated inoculum enhances inducible resistance without imposing detectable growth penalties. Priming significantly reduced disease severity, with primed plants (P\u2009+\u2009B) showing a 2.6-fold lower percent disease index compared to non-primed controls (B). Biochemical analyses revealed enhanced photosynthetic pigments (Chlorophyll a 2.6-fold, Chlorophyll b 3.3-fold, Carotenoids 1.56-fold), increased antioxidant defenses (Superoxide Dismutase 1.4-fold, Catalase 1.4-fold, and Ascorbate peroxidase 1.5-fold, ascorbic acid 2.8-fold, proline 1.6-fold), reduced lipid peroxidation (4.1-fold decrease), and higher phenolic content (1.8-fold) along with elevated PAL (1.9-fold) and POX (1.5-fold) activity. Yield traits also improved, including 1.4-fold higher spike number, 2.0-fold greater spikelet fertility, and a 1.2-fold increase in thousand grain weight (TGW). Strikingly, these benefits were transmitted to the F1 generation, demonstrating that pathogen-mediated defense priming can induce intergenerational immune priming (IGIP). Taken together, our findings establish pathogen-mediated green vaccination as a sustainable strategy to enhance wheat resilience and provide durable protection against spot blotch.\n\nID: 42252558\nTitle: Superoxide Dismutase-Centered Modulation by Curcumin in Cardiovascular Diseases: Mechanistic Insights and Translational Implications.\nAbstract: Cardiovascular diseases (CVD) remain the leading global cause of morbidity and mortality, driven in part by dysregulated redox homeostasis and chronic inflammation. Superoxide dismutase (SOD), a key enzymatic defence against reactive oxygen species (ROS), plays a central role in maintaining cardiovascular integrity through regulation of oxidative stress across cytosolic (SOD1), mitochondrial (SOD2) and extracellular (SOD3) compartments. Impairment of SOD function contributes directly to endothelial dysfunction, myocardial injury and vascular remodelling. Curcumin (Cur), a pleiotropic polyphenol derived from Curcuma longa, has emerged as a potent modulator of SOD activity and expression. Evidence from preclinical models consistently demonstrates that Cur enhances SOD-dependent antioxidant defences, thereby attenuating oxidative damage, inflammation, apoptosis and fibrosis across multiple CVD contexts, including myocardial infarction, cardiomyopathy, hypertension and diabetic complications. While Cur also influences additional signalling pathways, such as NF-\u03baB, PI3K/AKT and Nrf2, these effects are increasingly understood to converge on SOD-mediated redox regulation. Recent advances in nanodelivery systems have further improved Cur bioavailability and its capacity to modulate SOD activity in\u00a0vivo. However, despite robust preclinical evidence, clinical validation remains limited. This review synthesizes current mechanistic and translational evidence, positioning SOD as the central mediator of Cur's cardioprotective effects and highlights key gaps in clinical translation.\n\nID: 42240799\nTitle: Synaptic Plasticity Changes in the Somatosensory Cortex During Amyotrophic Lateral Sclerosis Progression and After Swim Training in SOD1-G93A Mice.\nAbstract: Somatosensory cortex hyperexcitability is present in the pre-symptomatic stage of amyotrophic lateral sclerosis (ALS) as evidenced by brain recordings, but its synaptic basis remains unclear. We examined synaptic plasticity, the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses, dendritic spine morphology, and the putative excitatory/inhibitory (E/I) ratio in the B2 barrel of the somatosensory cortex in female mice of an ALS mouse model. Transgenic mice, B6SJL-Tg (SOD1*G93A)1Gur/J, were used as the ALS model, and wild-type (WT) B6SJL/F1 mice served as controls. ALS mice were allocated to experimental groups based on disease stage (pre-symptomatic, onset, or terminal) and training condition (swim-trained or untrained). Swim training was applied after the first onset of symptoms (clinical score 1). We analyzed and quantified the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses and E/I ratios using serial electron micrographs to understand how these parameters change during disease progression and whether swim training influences this process. Our results showed stage-dependent alterations in asymmetric (putative excitatory) and symmetric (putative inhibitory) synaptic architecture in ALS. The obtained data showed an increase in the excitatory synaptic density in the presymptomatic ALS mice. This finding is consistent with previous reports of early cortical hyperexcitability and may reflect structural alterations associated with an initial increase in excitatory synapses before disease onset. Importantly, we report here an increase in inhibitory synapses at disease onset. TEM-based synaptic density quantification revealed reduced excitatory synapse density in the B2 barrel of the somatosensory cortex of trained ALS mice compared to WT controls, alongside a trend toward a reduced putative excitatory/inhibitory synaptic ratio. However, as no significant differences were detected between trained and untrained ALS mice, the contribution of swim training to these alterations remains unclear. Notably, swim training was not associated with detectable adverse effects on somatosensory cortex ultrastructure, excitatory synapse density, or the putative excitatory/inhibitory ratio, supporting previous observations that swim training is well tolerated under these experimental conditions. To our knowledge, these results provide the first TEM-based ultrastructural characterization of synaptic architecture in swim-trained SOD1-G93A mice, although further studies are needed to establish the underlying mechanisms and therapeutic relevance in ALS.\n\nID: 42213237\nTitle: Reevaluating the role of beta2-microglobulin: new insights on selective vulnerability in ALS pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterized by the selective loss of motor neurons (MNs). Why these neurons are particularly vulnerable in ALS remains\u00a0unclear, as does why certain MN groups\u00a0remain resistant\u00a0throughout the disease course. We investigated the role\u00a0of the human leukocyte antigens (HLAs) and beta2-microglobulin (\u03b22m) in MN susceptibility to ALS, given their reported involvement in\u00a0both prolonging and shortening disease\u00a0progression. Loss of HLAs in ALS has also been\u00a0shown to increase MNs vulnerability to toxicity exerted by activated astrocytes. RNA\u00a0sequencing of control tissues\u00a0demonstrated that disease-resistant oculomotor neurons (OMNs) and Onuf's MNs exhibited \u03b22m and HLA mRNA levels comparable\u00a0to those of\u00a0vulnerable spinal MNs, suggesting that\u00a0baseline differences in these transcripts do not explain the differential vulnerabilities\u00a0of\u00a0these MN groups. However, HLA protein levels showed an inverse correlation with spinal MN size, with the large MNs, those lost early in ALS, displaying the\u00a0lowest HLA expression. HLA protein levels were also reduced in spinal MNs from\u00a0end-stage ALS patient\u00a0tissues, while remaining relatively\u00a0unchanged in OMNs. In contrast, spinal MNs uniquely exhibited significant upregulation of \u03b22m and HLA-C transcripts during disease, likely reflecting a protective compensatory response. Together,\u00a0these findings suggest that \u03b22m and HLAs may contribute to spinal MN\u00a0vulnerability in ALS. To assess their functional role, \u03b22m\u00a0knockout mice were crossbred\u00a0with SOD1G93A ALS mice. Loss of \u03b22m\u00a0did not alter life span\u00a0of the ALS mice, but led to\u00a0partial preservation of lumbrical muscle\u00a0innervation that\u00a0was insufficient to maintain motor function. Analysis of GFAP immunoreactivity revealed marked neuroinflammation activation\u00a0in the\u00a0spinal cords of \u03b22m knockout mice. As these mice retain normal MN numbers\u00a0and life-span, this indicates that loss of functional MHC-I, even in the presence of\u00a0astrocyte activation, is insufficient to cause MN disease. Furthermore, \u03b22m knockout significantly increased GFAP activation in SOD1G93A mice, but did not further exacerbate disease progression, suggesting\u00a0that loss of functional MHC-I does not necessarily render MNs more vulnerable to\u00a0astrocyte toxicity. Overall,\u00a0these findings indicate that \u03b22m and HLAs are dynamically regulated in ALS, and may influence MN vulnerability, but they are not major disease\u00a0modifiers in ALS.\n\nID: 42212756\nTitle: 5-Hydroxytryptamine Distribution Alteration in Both Neuron and Synapse of Tg(SOD1*G93A)1gur Mice: A Potential Intervention Candidate Strategy for Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease; the precise pathogenesis of sporadic ALS (sALS) has not yet been elucidated up to now. Previous studies revealed that the abnormal alterations of some non-motor neurons (non-MN) were a potential pathogenesis of sALS. Therefore, this study aims to search the potential evidences of non-MN in the pathogenesis of ALS via exploring potential relationships between 5-hydroxytryptamine (5-HT) neurons and the development of ALS. We employed fluorescent immunohistochemistry to investigate the altered distribution patterns of 5-HT and tryptophan hydroxylase 2 in the spinal cord and brainstem of Tg(SOD1*G93A)1Gur (TG) and wild-type (WT) mice. Additionally, we used western blot to analyze the expression levels of 5-hydroxytryptamine receptor 1A (5-HTR1A) and 5-HTR2A. Our findings revealed that 5-HT synapses were primarily distributed in the funiculus lateralis, anterior horn, posterior horn, central lateral column, and the area around the central canal of cervical, thoracic, and lumbar segments, and raphe nucleus as well as lateral paragigantocellular nucleus, and gradually reduced following age increase in WT mice. However, 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem gradually increased following the progression of disease and presented a significantly negative correlation between the increased distribution of 5-HT synapses and neurons and the reduction of neural cell number (positively correlated with the increase in neural cell death) at the onset and/or progression stage of TG mice. 5-HTR1A significantly increased, while 5-HTR2A significantly decreased at the onset stage of TG mice. Our study speculated that the distribution changes of 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem play a potential protective role in the pathogenesis of sALS through a compensatory 5-HT increase.\n\nID: 42199117\nTitle: An integrated single-nucleus ribonucleic acid sequencing and spatial transcriptomic atlas reveals stage-specific neuronal and glial trajectories in a mouse model of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a progressive multifocal neurodegenerative condition involving motor neurons and other cell types. To analyze spatiotemporal cellular dynamics in amyotrophic lateral sclerosis, we performed single-nucleus ribonucleic acid sequencing and spatial transcriptomics analysis of cervical spinal cords from wild-type control mice and SOD1-G93A transgenic mice in the pre-symptomatic (d50), early symptomatic (d90), and late-stage (d130) phases of disease. Single-nucleus ribonucleic acid sequencing identified 17 cell clusters and showed that progressive neuronal loss occurred over time, paralleled by glial expansion. Spatial transcriptomics mapped these clusters anatomically onto oligodendrocytes in white matter, neurons in horns, and diffuse astrocytes/microglia. Subcluster analysis demonstrated neuronal heterogeneity, with early mitochondrial stress in ventral motor neurons evolving into synaptic dysfunction, transient maturation peaks in interneurons, and amplified age-related decline in amyotrophic lateral sclerosis. Astrocyte and oligodendrocyte subclusters, which were originally misclustered due to spot-level contamination, were reinterpreted to highlight A1-reactive states and progenitor expansions, validated by immunohistochemistry detection of serum/glucocorticoid regulated kinase 1. Temporal profiles tracked the transition from compensatory to inflammatory gliosis, while gene signatures were linked to human amyotrophic lateral sclerosis cohorts, including complement activation and mitochondrial dysfunction. This study provides a high-resolution spatiotemporal cellular map of amyotrophic lateral sclerosis pathogenesis through the integration of single-nucleus and spatial transcriptomics, uncovering early mitochondrial impairment in neurons, delineating the trajectory of neurotoxic glial states, and identifying compensatory progenitor responses, to highlight the highly intricate interaction between glial reactivity and neuronal susceptibility that drives the pathogenesis of ALS.\n\nID: 42195033\nTitle: From Mutation to Manifestation: Penetrance in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by progressive loss of motor neurons in the brain and spinal cord. While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS.\n\nID: 42193374\nTitle: 8-Epi-Prostaglandin F2\u03b1 as a Redox Biomarker in Inflammatory Bowel Disease.\nAbstract: Background: Oxidative stress plays a significant role in inflammatory bowel disease (IBD), yet the clinical relevance of specific lipid peroxidation markers remains insufficiently defined. This study evaluated serum levels of 8-epi-prostaglandin F2\u03b1 (8-epi-PGF2\u03b1), an isoprostane generated through non-enzymatic lipid oxidation, and examined its relationship with antioxidant enzymes and clinical disease activity in ulcerative colitis (UC) and Crohn's disease (CD). Methods: Eighty-seven patients (55 UC and 32 CD) were assessed for serum 8-epi-PGF2\u03b1, superoxide dismutase 1 (SOD1), and glutathione peroxidase 1 (GPX1), and classified as having mild, moderate, or severe disease. Statistical analyses included comparative analysis, two-way ANOVA, multiple linear regression, and Ridge logistic regression. To address potential dietary confounding, total energy intake, Mediterranean Diet Score (MDS), and antioxidant supplement use were incorporated into the regression models. Results: Serum levels of 8-epi-PGF2\u03b1 and GPX1 were significantly higher in UC than in CD (\u03c1 = 0.001 and p = 0.042), and both increased with greater disease severity (p < 0.001 and p = 0.001). In UC, 8-epi-PGF2\u03b1 positively correlated with high-sensitivity C-reactive protein (hs-CRP), white blood cells (WBC), and Truelove-Witts Index (TWI), and negatively with hemoglobin (False Discovery Rate (FDR)-adjusted q < 0.100). In CD, it correlated with the Harvey-Bradshaw Index (HBI) and disease duration (FDR-adjusted q < 0.050). Inter-biomarker analyses showed a strong association between 8-epi-PGF2\u03b1 and GPX1 in UC (\u03c1 = 0.677, p < 0.0001, FDR < 0.0001), suggesting coordinated activation of oxidative and antioxidant pathways. The observed associations remained consistent after adjustment for dietary factors, supporting the robustness of the findings. Because these results are cross-sectional, they cannot establish causality and should be interpreted with caution. Conclusions: Nevertheless, 8-epi-PGF2\u03b1 emerges as a promising non-invasive biomarker for assessing oxidative stress and disease activity in IBD, with potential clinical applicability for patient monitoring and therapeutic evaluation.\n\nID: 42193214\nTitle: Protective Effects of Cashew Apple Bagasse and Its Hydroethanolic Extract Against Fatty Liver in Rats.\nAbstract: Cashew apple bagasse (Anacardium occidentale L.) is an agro-industrial byproduct rich in fiber and phytochemicals, yet its effects on diet-induced fatty liver remain insufficiently characterized. This study evaluated the protective effects of cashew apple bagasse (CAB) and its hydroethanolic extract (HECAB) in rats fed a high-fat, high-carbohydrate (HFHC) diet. The proximate composition of CAB and the phenolic profile and antioxidant capacity of HECAB were characterized. Male Wistar rats were assigned to four groups and fed for 19 weeks with a standard diet, an HFHC diet, or an HFHC diet supplemented with CAB or HECAB. Anthropometric, biochemical, histological, immunohistochemical, and immunoblot analyses were performed. HECAB showed high phenolic content and marked radical-scavenging activity, and untargeted UPLC-QTOF-MS analysis yielded 12 putative secondary metabolite annotations (levels 3-4) based on accurate mass, isotope distributions, MS/MS fragmentation patterns, and predefined acceptance criteria. Relative to the standard diet group, the HFHC diet induced metabolic and hepatic alterations consistent with early-stage MASLD. Compared with HFHC, both CAB and HECAB reduced serum insulin and HOMA-IR, attenuated hepatic steatosis, increased SOD1 and CAT, and reduced NF-\u03baB, IL-6, TNF-\u03b1, and IL-1\u03b2, whereas GPx1 remained unchanged. Both interventions also enhanced NRF2 and HO-1 compared to HFHC, with stronger nuclear positivity in the HECAB group, while CAB showed the clearest association with IL-10 restoration. These findings are consistent with modulation of antioxidant defense- and inflammatory-related pathways in early-stage MASLD and support further investigation of cashew apple bagasse as a valorized functional ingredient. However, because classical oxidative damage markers were not measured, these results should not be interpreted as direct evidence of reduced oxidative stress. In addition, the detected metabolites should be interpreted as putative annotations rather than definitive compound identifications.\n\nID: 42184491\nTitle: Real-time profiling of brazilin-induced cytotoxic responses in HepG2 cells and exosome-associated metabolic signaling under lipid accumulation.\nAbstract: Hepatocellular carcinoma (HCC) frequently arises in metabolically altered livers and often exhibits limited responses to systemic therapies, highlighting the need for agents that target both tumor cell survival and metabolic vulnerabilities. Brazilin, a bioactive compound from Caesalpinia sappan, has been reported to exert anticancer activities, yet its effects on intercellular communication under lipid-enriched conditions remain unclear. Here, we profiled brazilin-induced cytotoxic responses in HepG2 cells using real-time imaging-based monitoring of cell morphology, number, and area, together with viability assays. Brazilin reduced HepG2 viability in a concentration-dependent manner and suppressed pro-survival signaling (Akt phosphorylation and Bcl-2), accompanied by caspase-3 cleavage and increased Annexin V positivity, indicating apoptosis-associated cytotoxicity. We then isolated extracellular vesicles released from brazilin-treated HepG2 cells and confirmed exosome-like characteristics by TEM, exosomal marker expression (CD9/CD63/CD81), and nanoparticle tracking analysis. Notably, in palmitate/oleate-loaded HepG2 cells, exosomes derived from brazilin-treated cells modulated metabolic and stress-associated proteins, including reduced CPT1A and SOD1 levels and increased p27 expression, consistent with altered fatty-acid oxidation-related signaling under lipid accumulation. Collectively, these findings suggest that brazilin exerts direct cytotoxic effects in HepG2 cells and that exosomes released upon brazilin exposure may contribute to metabolic signaling changes in lipid-loaded cancer cells.\n\nID: 42177410\nTitle: Integrated transcriptomic and metabolomic analyses reveal melatonin-mediated drought response in red raspberry at the squaring stage.\nAbstract: Red raspberry (Rubus idaeus L.) cultivation is often constrained by drought stress, which reduces fruit yield and quality. Melatonin (MT) plays an important role in plant stress tolerance. This study examined how exogenous MT improves drought tolerance in red raspberry at the squaring stage. It focused on changes in photosynthetic performance, antioxidant capacity, leaves anatomical structure, gene expression, and hormone homeostasis. Drought stress significantly reduced photosynthetic performance, antioxidant enzyme activities, and hormone homeostasis in red raspberry, and altered leaves anatomical structure. Exogenous MT treatment, particularly at 150\u00a0\u03bcmol L\u207b1, effectively alleviated these drought-induced effects. MT increased net photosynthetic rate and stomatal conductance, reduced oxidative damage, and promoted osmotic accumulation. At the anatomical level, MT-treated leaves showed more compact spongy tissue, increased palisade tissue and leaves thickness under drought stress. Transcriptomic and metabolomic analyses further revealed coordinated molecular changes under MT treatment. These changes mainly involved photosynthesis, carbohydrate and starch metabolism, plant hormone signaling, and amino acid metabolism. Genes related to photosynthetic function (PNSL3 and PNSB4), carbohydrate metabolism (glgc and PYG), antioxidant defense (SOD1 and sodC), and auxin signaling (AUX1 and SAUR) showed marked expression changes under MT treatment. Metabolite profiling also revealed changes in sugars, amino acids, phenolic compounds, and hormone-related compounds. Several transcription factor families, including bHLH, MYB-related, NAC, WRKY, and ERF, showed strong responses to MT. These changes were associated with transcriptional regulation and metabolic adjustment under drought stress. Exogenous MT significantly improved drought tolerance in red raspberry at the squaring stage, with 150\u00a0\u03bcmol L\u207b1 showing the best overall performance. This protective effect was associated with improved photosynthetic performance, enhanced antioxidant capacity, and better maintenance of leaves structure. Integrated transcriptomic and metabolomic analyses further revealed changes in hormone-related and metabolic pathways. These findings indicate that MT enhanced drought tolerance in red raspberry through coordinated physiological, anatomical, and molecular responses.\n\nID: 42171198\nTitle: Targeting lipid nanoparticle mediated co-delivery of edaravone and kaempferol for amyotrophic lateral sclerosis therapy.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterized by a progressive and selective loss of motor neurons in the central nervous system, particularly in the brain and spinal cord. However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system.\n\nID: 42164629\nTitle: Computational pathology with dynamic convolutional and adaptive kernels.\nAbstract: Data processing and learning have become essential to the advancement of medicine, with pathology and lab medicine being no exception. Integrating scientific research with clinical informatics into clinical practice facilitates novel methodologies for patient care. Computational pathology is a burgeoning subspecialty in pathology that promises a better-integrated solution to histopathological images and clinical informatics. Deep-learning methods in computational pathology have demonstrated considerable advances in automated histopathological image analysis. However, convolutional neural networks (CNNs) face fundamental limitations when dealing with the significant morphological heterogeneity present in disease tissues. Conventional CNNs use fixed convolutional kernels, which restrict their effectiveness in adaptively extracting features from histopathological images that exhibit diverse pathological patterns, staining intensities, and tissue architecture. To address this substantial limitation, we present an optimized variant of Omni-Dimensional Dynamic Convolution (ODConv) networks for distinguishing diseased tissue from healthy tissue. Compared with prior dynamic convolution methods that attend to a single kernel dimension, ODConv applies multi-dimensional attention across spatial positions, input channels, output channels, and kernel candidates, enabling more flexible and adaptive feature extraction. We evaluated our approach on wheat-germ agglutinin-stained and hematoxylin and eosin-stained skeletal muscle images from multiple disease models, including G93A*SOD1 transgenic mice (amyotrophic lateral sclerosis) and Akita mice (Type I diabetes). ODConv, trained entirely from scratch without ImageNet pretraining, achieved competitive classification performance relative to seven fine-tuned pretrained architectures across both staining modalities, demonstrating the effectiveness of omni-dimensional dynamic kernels in learning discriminative morphological representations directly from domain data. The study reports strong statistical agreement metrics, proving effective class balance handling and stable decision boundaries. These findings confirm ODConv as a strong computational pathology framework that advances automated diagnosis of neurodegenerative and metabolic skeletal muscle disorders.\n\nID: 42134658\nTitle: The impact of long-term feeding with curcuminoids phospholipids enriched diet on disease progression of fALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a debilitating and fatal neurodegenerative disease characterised by the progressive loss of motor functions affecting both upper and lower motor neurons. Although considered multifactorial with an unclear aetiology, it is believed that the interplay between genetic and environmental factors, with neuroinflammation playing a key role in disease progression, contributes to its development. There is currently no effective treatment for ALS. Curcumin has been recently highlighted for its potential therapeutic role in treating neurodegenerative diseases. Curcumin phospholipids, a highly bioavailable form of curcumin that allow the curcumin to be absorbed into the bloodstream more effectively than standard curcumin extracts, is considered as a natural cytokine-suppressive anti-inflammatory compound (CSAID) that is well-known for its therapeutic properties and is considered safe for humans and rodents at low to moderate concentrations. In this study, we investigated whether a long-term feeding regimen incorporating curcuminoids phospholipids-enriched diet early in disease progression could mitigate motor deficits and affect the lifespan of the SOD1 mouse model of familial ALS (fALS). Our results indicate sex-differences regarding the effect of curcumin supplementation on motor deficits and anxiety-like behaviour. While long-term feeding with curcuminoids phospholipids enriched diet had a complex effect on SOD1 female mice expressed as reduced anxiety like behaviour and motor deficits at the walking beam test, it had no effect on SOD1 male mice. Moreover, curcuminoids supplementation had a limited effect on disease onset and progression in SOD1 mice model for fALS.\n\nID: 42127907\nTitle: S-acylation of TDP43 regulates its condensation in amyotrophic lateral sclerosis.\nAbstract: TDP43 inclusion bodies are widely present in the majority of patients with familial and sporadic amyotrophic lateral sclerosis (ALS). The mechanisms regulating TDP43 solubility remain incompletely understood. Here, we report that TDP43 undergoes S-acylation primarily at the Cys244 residue by the S-acyltransferase zDHHC23. This S-acylation maintains the liquid-like properties of TDP43 by reducing the aberrant interaction with poly(ADP-ribose) polymerase 1 (PARP1) and PARylated proteins, thereby countering the pathological condensation of TDP43. S-acylation-deficient TDP43 inclusions sequester the translational machinery and inhibit cytoplasmic protein translation, ultimately resulting in neurotoxicity. Importantly, TDP43 S-acylation is decreased in the familial ALS-associated TDP43 mutants as well as in SOD1-G93A mice and C9orf72-ALS induced pluripotent stem cell (iPSC)-derived neurons, suggesting the widespread involvement of TDP43 S-acylation in ALS pathogenesis. Our findings reveal an undescribed modification of TDP43 and provide deeper insight into the regulation of TDP43 pathological condensation in ALS.\n\nID: 42125835\nTitle: Tracking Protein Misfolding and Oligomerization: A Temperature-Controlled Ion Mobility-Mass Spectrometry Approach.\nAbstract: Aberrant protein oligomerization is a hallmark of neurodegenerative disorders, yet the conformational and kinetic underpinnings of early aggregation remain poorly understood due to the inability of structural techniques to capture transient, low-abundance oligomeric intermediates. This necessitates the development of a methodology that can characterize the conformational states related to protein unfolding and thus allow for the investigation of the molecular mechanism responsible for disease progression. Here, we demonstrate how temperature-controlled nanoelectrospray ionization (TC-nESI) combined with high-resolution ion mobility-mass spectrometry (IM-MS), surface-induced dissociation (SID), and limited proteolysis can be used to define the misfolding and oligomerization landscape of bovine Cu/Zn superoxide dismutase (SOD1). This integrative approach enables real-time detection of coexisting intermediates, and captures molecular events including metal-induced stability, monomer unfolding and assembly into heterogeneous soluble oligomers. Our results reveal that both holo- and apo-SOD1 undergo dimer dissociation followed by monomer misfolding and assembly into heterogeneous non-native oligomers, and that slow thermal ramping promotes the accumulation of misfolded monomers and higher-order complexes. Apo-SOD1 that lacks stabilizing metal cofactors, forms more compact and kinetically distinct oligomers via monomeric, dimeric and trimeric intermediates. Proteolysis and heat-induced fragmentation identify loops V, VI, VII, and the C-terminus as key labile regions contributing to oligomer interface formation, predominantly through hydrophobic interactions. Our findings establish a mechanistically rich model for early aggregation and demonstrate the capability of TC-nESI-IM-MS to temporally and structurally resolve misfolding transitions and oligomeric populations in a single experiment. This platform provides a framework to dissect oligomerization pathways relevant to neurodegenerative diseases.\n\nID: 42327579\nTitle: Assessing the Association Between Genetic Variants in ACE, SOD1, and PER3 and their Role in Breast Cancer Risk among Jordanian Women.\nAbstract: Genetic and environmental factors regulate many physiological processes in the human body, and alterations in these processes may contribute to the development of various diseases, including breast cancer (BC), which is considered the most prevalent cancer among women and a leading cause of cancer-related mortality in the Jordanian population. Genes such as ACE, SOD1 and PER3 play important roles in regulating essential biological functions. These genes are involved in key physiological pathways, including blood pressure regulation, oxidative stress response and circadian rhythm maintenance, and genetic variants within them may influence susceptibility to cancer. Therefore, this study investigates the association between polymorphisms in the ACE, SOD1 and PER3 genes and the risk of breast cancer, with the aim of evaluating how these genetic variations relate to breast cancer susceptibility and clinical outcomes in Jordanian women. Blood samples of 300 women diagnosed with breast cancer, along with 300 healthy participants, were collected, and DNA was extracted from them. Genetic variants in the ACE (rs1799752), SOD1 (rs36232792) and PER3 (rs57875989) genes are examined through employing direct PCR to amplify the target regions. The ACE (rs1799752) variant was observed to be associated with breast cancer susceptibility, with the I/I genotype increasing risk of breast cancer (OR = 5.138, 95% CI = 1.38-19.03, p = 0.014). No associations were observed for SOD1 (rs36232792) and PER3 (rs57875989) variants. The rs1799752 polymorphism is suggested to have the potential of serving as a biomarker for breast cancer susceptibility in Jordanian women, as it is associated with elevating the risk.\n\nID: 41870290\nTitle: Scalable assay to identify inhibitors of prion-like propagation of protein misfolding as potential therapeutics for neurodegeneration.\nAbstract: Protein misfolding is linked to many neurodegenerative diseases. In some cases, misfolding can propagate through a prion-like mechanism whereby natively folded molecules are converted into more copies of the misfolded isoform. Prion-like propagation of misfolding is an attractive therapeutic target, but difficulties with assaying conversion directly and simply have severely limited efforts to find drugs targeting conversion of disease-related proteins. Here, we demonstrate a scalable enzymatic assay for testing potential inhibitors of prion-like conversion in superoxide dismutase-1 (SOD1), whose misfolding is linked to amyotrophic lateral sclerosis (ALS). We tested several small-molecule inhibitors of SOD1 aggregation to determine if they also inhibited prion-like conversion. We found that some compounds, like telbivudine and cisplatin, did indeed significantly delay conversion, but others, like baicalein and quercetin, had little effect. Surprisingly, some compounds, like two statins tested, actually accelerated conversion, suggesting that they might act to promote ALS progression. These results underline the fact that conversion and aggregation are distinct biophysical processes. The ability of the assay to identify compounds effective at delaying prion-like conversion holds out promise for applications in future drug discovery efforts that target propagated misfolding specifically.\n\nID: 41821425\nTitle: Tofersen treatment in SOD1 p.Leu145Phe ALS: real-world outcomes in a genetically homogeneous Croatian cohort.\nAbstract: Background: Antisense oligonucleotide tofersen targets SOD1 mRNA and reduces production of misfolded SOD1 protein, with demonstrated biomarker and functional signals in clinical trials and open-label extensions. Real-world reports from genetically heterogeneous SOD1 ALS cohorts describe variable functional trajectories. Data from genetically homogeneous founder populations remain limited. We investigated clinical trajectories in a cohort carrying the same pathogenic SOD1 variant to better characterize mutation-specific patterns in a real-world setting. Methods: We conducted a single-center observational study at the National Referral Center for Neuromuscular Diseases and Clinical Electromyoneurography (UHC Zagreb, Croatia). Eight adults with genetically confirmed SOD1 p.Leu145Phe ALS received intrathecal tofersen according to the approved regimen. ALS Functional Rating Scale-Revised (ALSFRS-R) scores were recorded at each dosing visit, and longitudinal slopes were calculated using linear regression. Safety and tolerability were evaluated descriptively. Biomarker and formal respiratory measurements were not routinely available. Results: All patients exhibited lower limb-onset, predominantly lower motor neuron phenotypes consistent with a slow-progressing founder variant. Median age at symptom onset was 60\u2009years, and median therapeutic delay was 48\u2009months. Median on-treatment ALSFRS-R slope was -0.28 points/month (range +0.04 to -0.57). Two patients demonstrated stable trajectories, while the remainder showed gradual decline. These patterns fall within the slower range reported in heterogeneous real-world SOD1 cohorts and are consistent with the known natural history of this mutation. Tofersen was well tolerated, with no serious treatment-related adverse events. Conclusions: In this genetically homogeneous SOD1 p.Leu145Phe cohort, functional trajectories during tofersen therapy reflected the mutation's slow-progressing phenotype. These findings provide real-world clinical context but do not permit conclusions regarding treatment efficacy. Further mutation-specific studies incorporating prospective baseline assessment and biomarker monitoring are needed to clarify therapeutic impact.\n\nID: 41742554\nTitle: Development and pilot testing of U1 Adaptor therapy targeting SOD1 expression for dogs with degenerative myelopathy.\nAbstract: Degenerative myelopathy (DM) is a progressive neurodegenerative disease in dogs associated with a superoxide dismutase 1 (SOD1) gene mutation, resulting in SOD1 protein aggregation within neurons and astrocytes. Targeting SOD1 expression represents a viable therapeutic strategy. Assess the safety and potential efficacy of SOD1 silencing by intrathecal administration of a U1 Adaptor oligonucleotide targeting canine SOD1 (U1cSOD1) in healthy and DM-diseased dogs. Seven purpose-bred healthy adult dogs, 1 dog with stage III DM and 4 dogs with Stage I DM. Healthy dogs and the stage III DM dog received a single intrathecal dose of U1cSOD1 or a vehicle and were euthanized 5 or 30\u00a0days later. Four stage I DM-affected dogs received monthly intrathecal injections of U1cSOD1 for up to 10\u00a0months. Physical and neurologic examinations, blood tests, cerebrospinal fluid analysis, as well as pharmacokinetic, pharmacodynamic, and histopathologic analyses were performed in all dogs. In dogs receiving U1cSOD1, spinal cord SOD1 RNA expression near the injection site was decreased to a median of 37% of normal (range, 21%-79%). Dogs tolerated the procedure and test agent well, exhibiting no adverse effects clinically or histopathologically. Two of 34 injections were aborted because of high intrathecal pressure. Monthly intrathecal injections of U1cSOD1 in DM-affected dogs are safe and decrease spinal cord SOD1 expression by >50% but an alternative administration route would be preferred. This first test of U1 Adaptor technology in dogs with a naturally occurring disease shows potential for therapeutic intervention in a fatal disease without a current cure.\n\nID: 41686369\nTitle: Extracellular vesicles at the neuromuscular junction: messengers of synaptic health and disease.\nAbstract: Extracellular vesicles (EVs) have emerged as pivotal modulators of neuromuscular junction (NMJ) biology, reshaping our understanding of synaptic communication, maintenance, and degeneration. This review consolidates current insights into the roles of EVs derived from motor neurons, muscle fibers, and Schwann cells in regulating NMJ integrity. In healthy states, EVs deliver trophic factors, structural proteins, and regulatory RNAs that promote the clustering of acetylcholine receptors, presynaptic stability, and axonal growth. Motor neuron EVs carry Wnt7a, synaptophysin, and PGC-1\u03b1, while muscle-derived EVs deliver miR-206, agrin, and caveolin-3. Schwann cell EVs contribute neurotrophic support via NRG1 and GDNF. In contrast, diseased or aged NMJs exhibit EV cargo dysregulation, marked by the presence of misfolded proteins (e.g., SOD1, TDP-43), pro-inflammatory cytokines, and reduced regenerative miRNAs. These changes contribute to synaptic dismantling, neuroinflammation, and impaired repair in conditions such as ALS, SMA, MG, and sarcopenia. The review highlights the bidirectional nature of EV signalling and its dynamic regulation by neuronal activity and stress. Emerging therapeutic strategies include engineering EVs to deliver protective cargo, targeting them to NMJ components, and designing biomaterial-based depots for sustained release. Furthermore, EV signatures in blood and muscle hold promise as non-invasive biomarkers for early detection of NMJ decline in ALS, SMA, MG, and sarcopenia. Despite promising preclinical data, challenges remain in EV characterization, targeting specificity, and clinical translation. This review underscores a paradigm shift: EVs are not passive byproducts but active messengers of neuromuscular health and disease, with realistic applications in diagnostics, regenerative therapy, and personalized medicine.\n\nID: 41640104\nTitle: Tofersen: A Novel Option for the Treatment of Amyotrophic Lateral Sclerosis.\nAbstract: This review summarizes current evidence on the efficacy and safety of tofersen (Qalsody) in treating amyotrophic lateral sclerosis (ALS). PubMed, MEDLINE, Google Scholar, and ClinicalTrials.gov were searched using the keywords: Qalsody, BIIB067, antisense oligonucleotides, SOD1, and amyotrophic lateral sclerosis. Articles published from inception to November 2025 were included. English-language studies assessing the pharmacokinetics, pharmacology, efficacy, and safety of tofersen were included. Prescribing information and real-world evidence were also reviewed. Tofersen is an intrathecally administered antisense oligonucleotide targeting superoxide dismutase 1 (SOD1) mRNA. Early trials demonstrate dose-dependent reductions in cerebrospinal fluid (CSF) SOD1 protein levels of -33% and slower ALS Functional Rating Scale (ALSFRS-R) decline compared to placebo (-1.19 vs -5.63 points). In Phase 3 trials, tofersen reduced CSF SOD1 by 29% and plasma neurofilament light chain (NfL) by 60%, while biomarkers increased in the placebo group. There was no significant difference in ALSFRS-R decline between tofersen and placebo (-6.98 vs -8.14; P = 0.97). Real-world data show favorable patient-related outcomes and improvement in ALSFRS-R. Adverse effects are primarily lumbar puncture related with serious neurologic events documented in 7% of tofersen recipients.Relevance to Patient Care and Clinical Practice in Comparison to Existing Drugs:As the first Food and Drug Administration (FDA)-approved gene-directed therapy for SOD1 ALS, tofersen directly targets the underlying genetic cause. Barriers include the need for genetic confirmation and intrathecal administration. Tofersen provides a promising targeted treatment option for pathogenic SOD1 ALS. Ongoing studies will clarify its long-term clinical impact.\n\nID: 41599628\nTitle: C16-siRNAs in Focus: Development of ALN-APP, a Promising RNAi-Based Therapeutic for Alzheimer's Disease.\nAbstract: This review examines a small interfering RNA (siRNA) designed for intrathecal (IT) injection, which reduces the formation of amyloid beta precursor protein (APP), a critical factor in the pathology of Alzheimer's disease (AD). The siRNA, designated ALN-APP, incorporates a 16-carbon chain (C16-siRNA) to enhance its delivery to the central nervous system (CNS) while leveraging advancements in specificity and duration of action based on previously approved drugs by the Food and Drug Administration. The development of ALN-APP involved a comprehensive analysis of the optimal carbon chain length and its conjugation position to the siRNA. Preclinical studies conducted on male Sprague Dawley rats, mice, and non-human primates (NHPs) demonstrated the efficacy of ALN-APP. In rats, an IT injection of C16-siRNAs at a concentration of 30 mg/mL, delivering a dose of 0.9 mg, resulted in cranial distribution via cerebrospinal fluid and led to a 75% reduction in copper-zinc superoxide dismutase 1 (SOD1) mRNA levels. These effects were dose-dependent and persisted for three months across multiple brain regions. Furthermore, studies in NHPs indicated that soluble APP levels were reduced to below 25%, sustained for two months. In the cerebrovascular amyloid Nos2-/- (CVN) mouse model of AD, administration of 120 \u00b5g of siRNA via the intracerebroventricular route produced reductions in APP expression, with mRNA levels remaining suppressed for 60 days in the ventral cortex. Indeed, ALN-APP controlled neuropathology in 5xFAD mice by significantly reducing amyloid levels and brain neuroinflammation, with improved behaviors in the elevated plus maze. Following these promising results in animal models, ALN-APP advanced to a Phase 1 trial, designated ALN-APP-001, which assessed its safety and efficacy in 12 participants with early-onset Alzheimer's disease (EOAD). Initial findings revealed a 55% reduction in soluble APP\u03b1 and a 69% reduction in APP\u03b2 by day 15. These exploratory findings require further validation with larger cohorts and proper statistical analysis. In a subsequent cohort of 36 patients, administration of the 75 mg dose via IT injection led to mean reductions of 61.3% in soluble APP\u03b1 (sAPP\u03b1) and 73.5% in soluble APP\u03b2 (sAPP\u03b2) after one month. These silencing effects persisted for six months and were associated with important decreases in A\u03b242 and A\u03b240 levels. These results highlight the potential of ALN-APPs to address Alzheimer's pathology while maintaining a favorable safety profile. Whether ALN-APP succeeds in further clinical trials, key challenges include ensuring accessibility and affordability due to treatment costs, the need for specialized intrathecal administration, and establishing infrastructure for large-scale production of siRNAs. In conclusion, advancements in ALN-APP represent a promising strategy to reduce beta-amyloid formation in AD, with substantial biomarker reductions suggesting potential disease-modifying effects. Continued development may pave the way for innovative treatments for neurodegenerative diseases.\n\nID: 41196070\nTitle: Unraveling the genetic landscape of ALS in Greece: identification of known and novel causative variants in a 353-patient cohort.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset, progressive, fatal neurodegenerative disorder characterized by progressive loss of motor neurons. Approximately 15% of individuals diagnosed with ALS have a known genetic variant that contributes to disease. Herein, we present clinical and genetic data of a large Greek ALS cohort. The cohort consisted of 353 Greek consecutive index patients with ALS, including 16 patients with related motor neuron disease (MND) subtypes (nine with PLS, four with PBP, and three with PMA). Next generation sequencing raw data (obtained from the NYGC ALS Consortium) were further analyzed and used to screen for causative variants in known implicated genes. Repeat expansions in C9ORF72 and ATXN2 were investigated using ExpansionHunter software, repeat-primed PCR and fragment analysis. Pathogenic repeat expansions in C9ORF72 were detected in 41 patients (11.6%). In addition, 30 patients (8.5%) carried a causative variant in one of the genes studied. Known causative variants were identified in 27 cases (nine in SQSTM1, seven in TARDBP, five in SOD1, three in NEK1 and one each in SETX, VCP, FUS), whereas novel causative variants were identified in three cases (SOD1, FIG4, TBK1). In total, 71 cases received a molecular genetic diagnosis (20.1%). Additionally, seven cases (2.0%) carried an intermediate repeat expansion (30-33 CAG) in ATXN2. Our results reveal the distinct genetic profile of Greek ALS patients. These findings will have an impact on genetic counseling, the design of diagnostic gene panels for the Greek population and on genotype-specific therapeutic interventions. Understanding the genetic causes of ALS in different populations is becoming increasingly important, especially with the advent of personalized medicine.\n\nID: 40475252\nTitle: Inhibitory effect of Fisetin against the aggregation process of SOD1 E100K mutant: computer-based drug design as a potential therapeutic for ALS disease.\nAbstract: Protein misfolding and aggregation in superoxide dismutase 1 (SOD1) are linked to the neurodegenerative disease amyotrophic lateral sclerosis (ALS). SOD1 mutations have a significant role in the pathophysiology and fast behavior of protopathic proteins in ALS illness. The E100K mutation may be useful in uncovering the pathogenic mechanism of SOD1 associated with ALS. According to several studies, giving small molecule inhibitors made from polyphenolic flavonoid compounds may be a viable treatment strategy for neurological conditions. Using molecular docking and MD simulations, we have identified a potential flavonoid drug that may successfully inhibit SOD1's amyloidogenic activity. Puerarin, Fisetin, and Peonidin provided intriguing pharmacological hints during the initial screening of flavonoids. The Fisetin-E100K complex had a larger residual energy contribution and substantial binding than other flavonoid compounds. The findings showed that, unlike other materials, Fisetin increased the structural stability, hydrophobicity, and flexibility of the mutant while reducing the amount of \u03b2-sheets. Furthermore, to distinguish aggregation in the mutant (unbound/bound) states, we displayed modifications in the free energy landscape (FEL). As a result, Fisetin was identified as having therapeutic potential against the E100K, which might make it a viable pharmacological option for the creation of inhibitors that lower the chance of ALS death.\n\nID: 40009238\nTitle: Advancements in genetic research and RNA therapy strategies for amyotrophic lateral sclerosis (ALS): current progress and future prospects.\nAbstract: This review explores the intricate landscape of neurodegenerative disease research, focusing on Amyotrophic Lateral Sclerosis (ALS) and the intersection of genetics and RNA biology to investigate the causative pathogenetic basis of this fatal disease. ALS is a severe neurodegenerative disease characterized by the progressive loss of motor neurons, leading to muscle weakness and paralysis. Despite significant research advances, the exact cause of ALS remains largely unknown. Thanks to the application of next-generation sequencing (NGS) approaches, it was possible to highlight the fundamental role of rare variants with large effect sizes and involvement of portions of non-coding RNA, providing valuable information on risk prediction, diagnosis, and treatment of age-related diseases, such as ALS. Genetic research has provided valuable insights into the pathophysiology of ALS, leading to the development of targeted therapies such as antisense oligonucleotides (ASOs). Regulatory agencies in several countries are evaluating the commercialization of Qalsody (Tofersen) for SOD1-associated ALS, highlighting the potential of gene-targeted therapies. Furthermore, the emerging significance of microRNAs (miRNAs) and long RNAs are of great interest. MiRNAs have emerged as promising biomarkers for diagnosing ALS and monitoring disease progression. Understanding the role of lncRNAs in the pathogenesis of ALS opens new avenues for therapeutic intervention. However, challenges remain in delivering RNA-based therapeutics to the central nervous system. Advances in genetic screening and personalized medicine hold promise for improving the management of ALS. Ongoing clinical trials use genomic approaches for patient stratification and drug targeting. Further research into the role of non-coding RNAs in the pathogenesis of ALS and their potential as therapeutic targets is crucial to the development of effective treatments for this devastating disease.\n\nID: 39730482\nTitle: Genetic epidemiology of amyotrophic lateral sclerosis in Cyprus: a population-based study.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating, uniformly lethal degenerative disease of motor neurons, presenting with relentlessly progressive muscle atrophy and weakness. More than fifty genes carrying causative or disease-modifying variants have been identified since the 1990s, when the first ALS-associated variant in the gene SOD1 was discovered. The most commonly mutated ALS genes in the European populations include the C9orf72, SOD1, TARDBP and FUS. Understanding the genetic causes of ALS within a population is becoming more significant, especially in light of the possible development of personalized medicine. Here, we provide clinical and genetic data on familial and sporadic ALS patients in a Greek-Cypriot population-based cohort. Eighty-nine ALS patients, including 21 familial ALS (fALS) (23.6%) and 68 sporadic ALS (sALS) (76.4%), provided the cohort for variant screening of the most common ALS-associated genes. Moreover, next-generation sequencing (NGS) was also performed to identify rare ALS variants, and in silico prediction tools were applied to predict the downstream effect of the variants detected in our study. The pathogenic hexanucleotide G4C2 repeat expansion in C9orf72 was the predominant genetic cause (22.47%) of ALS in our population, while variants in six additional ALS-associated genes were identified, including ALS2, TARDBP, FIG4, TBK1, GLT8D1, and BICD2.\n\nID: 39645085\nTitle: Lipid nanoparticles and transcranial focused ultrasound enhance the delivery of SOD1 antisense oligonucleotides to the murine brain for ALS therapy.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease with extremely limited therapeutic options. One key pathological feature of ALS is the abnormal accumulation of misfolded proteins within motor neurons. Hence, reducing the burden of misfolded protein has emerged as a promising therapeutic approach. Antisense oligonucleotides (ASOs) have the potential to effectively silence proteins with gain-of-function mutations, such as superoxide dismutase 1 (SOD1). However, ASO delivery to the central nervous system (CNS) is hindered by poor blood-brain barrier (BBB) penetration and the invasiveness of intrathecal administration. In the current study, we demonstrate effective systemic delivery of a next-generation SOD1 ASO (Tofersen) into the brain of wildtype and G93A-SOD1 transgenic C57BL/6 mice using calcium phosphate lipid nanoparticles (CaP lipid NPs). We show that transcranial focused ultrasound (FUS) with intravenously administered microbubbles can significantly enhance ASO-loaded nanoparticle delivery into the mouse brain. Magnetic resonance imaging (MRI) and immunohistological analysis showed reduced SOD1 expression in the FUS-exposed brain regions and increased motor neuron count in the spinal cord of treated mice suggesting decreased motor neuron degeneration. Importantly, the BBB opening was transient without evidence of structural changes, neuroinflammation or damage to the brain tissue, indicating that the treatment is well tolerated. Overall, our results highlight FUS-assisted nanoparticle delivery of ASOs as a promising non-invasive therapeutic strategy for the treatment of ALS and CNS diseases more broadly.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease.\n  --- END ACTUAL ABSTRACT FOR 42480869 ---\n\n- ERROR: You cited ID: 42343420 for the quote: \"LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression.\"\n  FACT: Strict Misquote Detected!

Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration.\n  --- END ACTUAL ABSTRACT FOR 42343420 ---\n\n- ERROR: You cited ID: 42127907 for the quote: \"TDP43 S-acylation is decreased in the familial ALS-associated TDP43 mutants as well as in SOD1-G93A mice and C9orf72-ALS induced pluripotent stem cell (iPSC)-derived neurons.\"\n  FACT: Strict Misquote Detected!

The mechanisms regulating TDP43 solubility remain incompletely understood. Here, we report that TDP43 undergoes S-acylation primarily at the Cys244 residue by the S-acyltransferase zDHHC23. This S-acylation maintains the liquid-like properties of TDP43 by reducing the aberrant interaction with poly(ADP-ribose) polymerase 1 (PARP1) and PARylated proteins, thereby countering the pathological condensation of TDP43. S-acylation-deficient TDP43 inclusions sequester the translational machinery and inhibit cytoplasmic protein translation, ultimately resulting in neurotoxicity. Importantly, TDP43 S-acylation is decreased in the familial ALS-associated TDP43 mutants as well as in SOD1-G93A mice and C9orf72-ALS induced pluripotent stem cell (iPSC)-derived neurons, suggesting the widespread involvement of TDP43 S-acylation in ALS pathogenesis. Our findings reveal an undescribed modification of TDP43 and provide deeper insight into the regulation of TDP43 pathological condensation in ALS.\n  --- END ACTUAL ABSTRACT FOR 42127907 ---\n\n- ERROR: You cited ID: 42240799 for the quote: \"We report here an increase in inhibitory synapses at disease onset.\"\n  FACT: Strict Misquote Detected!

We examined synaptic plasticity, the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses, dendritic spine morphology, and the putative excitatory/inhibitory (E/I) ratio in the B2 barrel of the somatosensory cortex in female mice of an ALS mouse model. Transgenic mice, B6SJL-Tg (SOD1*G93A)1Gur/J, were used as the ALS model, and wild-type (WT) B6SJL/F1 mice served as controls. ALS mice were allocated to experimental groups based on disease stage (pre-symptomatic, onset, or terminal) and training condition (swim-trained or untrained). Swim training was applied after the first onset of symptoms (clinical score 1). We analyzed and quantified the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses and E/I ratios using serial electron micrographs to understand how these parameters change during disease progression and whether swim training influences this process. Our results showed stage-dependent alterations in asymmetric (putative excitatory) and symmetric (putative inhibitory) synaptic architecture in ALS. The obtained data showed an increase in the excitatory synaptic density in the presymptomatic ALS mice. This finding is consistent with previous reports of early cortical hyperexcitability and may reflect structural alterations associated with an initial increase in excitatory synapses before disease onset. Importantly, we report here an increase in inhibitory synapses at disease onset. TEM-based synaptic density quantification revealed reduced excitatory synapse density in the B2 barrel of the somatosensory cortex of trained ALS mice compared to WT controls, alongside a trend toward a reduced putative excitatory/inhibitory synaptic ratio. However, as no significant differences were detected between trained and untrained ALS mice, the contribution of swim training to these alterations remains unclear. Notably, swim training was not associated with detectable adverse effects on somatosensory cortex ultrastructure, excitatory synapse density, or the putative excitatory/inhibitory ratio, supporting previous observations that swim training is well tolerated under these experimental conditions. To our knowledge, these results provide the first TEM-based ultrastructural characterization of synaptic architecture in swim-trained SOD1-G93A mice, although further studies are needed to establish the underlying mechanisms and therapeutic relevance in ALS.\n  --- END ACTUAL ABSTRACT FOR 42240799 ---\n\n- ERROR: You cited ID: 42196191 for the quote: \"NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal.

We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression. These findings suggest that longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.\n  --- END ACTUAL ABSTRACT FOR 42196191 ---\n\n- ERROR: You cited ID: 42164629 for the quote: \"We evaluated our approach on wheat-germ agglutinin-stained and hematoxylin and eosin-stained skeletal muscle images from multiple disease models, including G93A*SOD1 transgenic mice (amyotrophic lateral sclerosis).\"\n  FACT: Strict Misquote Detected!

Integrating scientific research with clinical informatics into clinical practice facilitates novel methodologies for patient care. Computational pathology is a burgeoning subspecialty in pathology that promises a better-integrated solution to histopathological images and clinical informatics. Deep-learning methods in computational pathology have demonstrated considerable advances in automated histopathological image analysis. However, convolutional neural networks (CNNs) face fundamental limitations when dealing with the significant morphological heterogeneity present in disease tissues. Conventional CNNs use fixed convolutional kernels, which restrict their effectiveness in adaptively extracting features from histopathological images that exhibit diverse pathological patterns, staining intensities, and tissue architecture. To address this substantial limitation, we present an optimized variant of Omni-Dimensional Dynamic Convolution (ODConv) networks for distinguishing diseased tissue from healthy tissue. Compared with prior dynamic convolution methods that attend to a single kernel dimension, ODConv applies multi-dimensional attention across spatial positions, input channels, output channels, and kernel candidates, enabling more flexible and adaptive feature extraction. We evaluated our approach on wheat-germ agglutinin-stained and hematoxylin and eosin-stained skeletal muscle images from multiple disease models, including G93A*SOD1 transgenic mice (amyotrophic lateral sclerosis) and Akita mice (Type I diabetes). ODConv, trained entirely from scratch without ImageNet pretraining, achieved competitive classification performance relative to seven fine-tuned pretrained architectures across both staining modalities, demonstrating the effectiveness of omni-dimensional dynamic kernels in learning discriminative morphological representations directly from domain data. The study reports strong statistical agreement metrics, proving effective class balance handling and stable decision boundaries. These findings confirm ODConv as a strong computational pathology framework that advances automated diagnosis of neurodegenerative and metabolic skeletal muscle disorders.\n  --- END ACTUAL ABSTRACT FOR 42164629 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model.\" (Source: 42406382)\n- \"This enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function.\" (Source: 42390843)\n- \"Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS.\" (Source: 42398690)\n- \"The ability of the assay to identify compounds effective at delaying prion-like conversion holds out promise for applications in future drug discovery efforts that target propagated misfolding specifically.\" (Source: 41870290)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The therapeutic focus has moved decisively toward reducing mutant SOD1 protein levels, with intrathecal tofersen emerging as a cornerstone intervention. Clinical data confirm robust target engagement, characterized by significant reductions in cerebrospinal fluid SOD1 protein and plasma neurofilament light chain (NfL) levels. Concurrently, basic research has elucidated the role of copper homeostasis in SOD1 stability, identifying that pathological copper overload can paradoxically suppress SOD1 activity via COMMD1, thereby exacerbating oxidative stress. Moreover, the crosstalk between oxidative stress and neuroinflammation is now viewed as a critical therapeutic target, with hydrogen therapy and immune checkpoint modulation (e.g., LAG-3) showing promise in preclinical models for preserving neuromuscular integrity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Copper Paradox:** High intracellular copper can inhibit SOD1 by disrupting its homodimerization, mediated by COMMD1-dependent mechanisms.\n*   **Catalytic Hydrogen Therapy:** Mutant SOD1 acts as both a Fenton-like agent producing hydroxyl radicals and a catalyst for hydrogen-based free radical scavenging.\n*   **Microglial LAG-3:** This immune checkpoint protein exerts stage-dependent regulation on microglial modules, dissociating inflammatory and phagocytic functions in ALS progression.\n*   **Prion-like Propagation:** Conversion of SOD1 into a misfolded isoform is a targetable biophysical process distinct from aggregation.\n*   **Statin Effects:** While statins can modulate antioxidant genes, they may also inadvertently accelerate prion-like conversion of SOD1 in some experimental contexts.\n*   **Computational Pathology:** Dynamic convolution networks (ODConv) can now distinguish SOD1-associated skeletal muscle pathology from other metabolic disorders using histopathological imagery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six).

Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study.

Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders."

Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot."

This work studies the metabolic effects of elevated phosphate on muscle. C2C12 cells were differentiated in the absence or presence of 10 mM \u03b2-glycerophosphate (BGP), an exogenous phosphate donor. In addition, quadriceps muscles from four experimental groups of male C57BL/6J mice were analyzed: young (5 months) and old (24 months) fed with standard diet; old mice fed with hypophosphatemic diet or supplemented with the phosphate binder Velphoro\u00ae, for the last three months of life. Mice were stratified according to sarcopenia degree based on muscle mass, strength and physical performance. Protein levels were determined by immunoblotting and mRNA expression by RT-qPCR. ATP levels were measured by luminescence and L-lactate production, citrate synthase and cytochrome c oxidase activities by colorimetric assays. Mitochondrial content, membrane potential and reactive oxygen species (ROS) were determined by fluorescence assay. BGP-treated cells showed increased glucose transporter 1 (GLUT1) and decreased NADH Dehydrogenase (CI-NDUFB8) protein expression, elevated hexokinase II (HK2), phosphoglycerate kinase 1 (PGK1) and lactate dehydrogenase A (LDHA) mRNA levels, reduced ATP levels, increased lactate production, and decreased mitochondrial enzyme activities. Moreover, BGP increased ROS, diminished mitochondrial membrane potential, and altered fusion-fission dynamics and mitophagy. In aged quadriceps, oxidative phosphorylation (OXPHOS) subunits and superoxide dismutase 2 (SOD2) expression were reduced. The hypophosphatemic diet improved all parameters, whereas Velphoro\u00ae selectively increased Mitochondrial cytochrome C oxidase subunit 1 (CIV-MTCO1) expression. Several altered mitochondrial markers are associated with sarcopenia degree. Altogether, hyperphosphatemia induces metabolic changes that scale with the sarcopenic degree. Our findings show a relevant association between hyperphosphatemia and mitochondrial dysfunction, and they support the potential benefit of phosphate reduction as a strategy to prevent or mitigate sarcopenia."

This study aimed to evaluate the toxic effects of Cd by assessing hematological parameters, antioxidant responses, and the expression of stress-related genes in C.\u00a0auratus exposed to waterborne Cd. A total of 180 healthy C.\u00a0auratus (19.43 \u00b1\u00a01.5 cm and 170.00 \u00b1\u00a03.04 g) were exposed to Cd at concentrations of 0, 2, and 4 mg/L for 8 weeks, with three replicates per treatment. The exposure to Cd resulted in significant reductions in red blood cell (RBC) count, hemoglobin (Hb) concentration, and hematocrit (Hct) values. Moreover, the levels of total superoxide dismutase (T-SOD), catalase (CAT), and glutathione peroxidase (GPx) in the liver also decreased significantly, whereas malondialdehyde (MDA) content was increased significantly.

Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers."

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability."

This evolution is driven by the regulatory approval and clinical integration of antisense oligonucleotides and siRNA-conjugates. Simultaneously, research has expanded to include systemic factors\u2014such as platelet-derived factors and autophagy-regulating small molecules\u2014and a high-resolution understanding of the \"disease-associated motor neuron\" (DM) state, which provides a conserved molecular roadmap for future therapeutic targeting.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe field of SOD1-ALS has undergone rapid transformation, defined by the clinical maturity of targeted gene-lowering therapies. The integration of such interventions into standard care has necessitated nationwide shifts in genetic testing protocols, as evidenced by the observation that 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Mechanistic studies now link toxic protein aggregation with converging cellular stressors, including mitochondrial failure and oxidative dysregulation. Emerging therapies target these specific pathological vulnerabilities; for instance, hydrogen gas scavenging and autophagic modulation demonstrate efficacy in preclinical SOD1-G93A models. The complexity of these interactions is reinforced by the identification of discrete \"disease-associated motor neuron\" states that precede physical degeneration, providing a temporal window for early therapeutic intervention. Despite these strides, research continues to navigate the clinical challenges posed by phenotypic dissociation and the limitations of targeting single proteins in a multifaceted neurodegenerative cascade.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Pathology-Selective Efficacy:** Therapeutic interventions like PF4 demonstrate robust rescue in SOD1-driven models but remain ineffective in TDP-43 or C9orf72 models.\n*   **Systemic Autophagy:** The discovery of a peripheral platelet-autophagy-neuron axis allows systemic factors to directly influence central proteostatic machinery.\n*   **Temporal Precision:** The identification of \"disease-associated motor neurons\" (DMs) suggests that motor neuron vulnerability is a staged molecular trajectory, not an abrupt event.\n*   **Hydrogen Therapy:** Mutant SOD1 acts as both a catalyst for hydroxyl radical generation and a potential hydrogenation catalyst, allowing for novel hydrogen-based scavenging therapies.\n*   **Diagnostic Evolution:** The shift from familial-only testing to universal screening for sporadic ALS reflects a clinical standard redefined by the availability of disease-modifying therapies.\n*   **Phenotypic Dissociation:** There is growing clinical recognition of biomarker-clinical dissociation, where functional decline may not always mirror molecular marker trends.\n*   **Targeting the Microenvironment:** Modulating the TREM2-mediated inflammatory state of microglia represents a viable pathway for slowing disease progression.\n*   **Compensatory Homeostasis:** SOD1-G93A spinal motoneurons display \"overactive\" homeostatic control, suggesting that dysfunction involves failed feedback regulation rather than simple excitability shifts.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Glabridin (Glab), a natural flavonoid derived from licorice, has been shown to mitigate stress-related damage due to its antioxidant properties. This study aims to assess the impact of Glab on OS-induced damage in the bovine immortalized cell line (BIECs-21), validate its effectiveness in vivo, and elucidate the underlying mechanisms. The in vitro OS model of BIECs-21 was established using 400 \u03bcM H2O2. The study evaluated cell viability, lactate dehydrogenase (LDH) activity, oxidative markers, inflammatory responses, and apoptosis in BIECs-21 under various treatment conditions. Additionally, the effects of Glab were investigated in a murine model of experimental colitis induced by dextran sulfate sodium (DSS). Glab improved cell viability, reduced LDH release, and mitigated the adverse effects of H2O2 on total anti-oxidation capacity (T-AOC), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) levels. qRT-PCR analysis revealed that H2O2 exposure resulted in decreased expression of nuclear factor erythroid 2-related factor 2 (Nrf2), superoxide dismutase 1 (SOD1), NADPH quinine oxidoreductase-1 (NQO1), and heme oxygenase-1 (HO-1), while it increased the expression of nuclear factor-kappa B (NF-\u03baB), tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-6 (IL-6), and interleukin-8 (IL-8), ultimately leading to apoptosis in BIECs-21. Notably, Glab supplementation partially reversed these effects. Similar benefits of Glab were observed in a DSS-induced colitis mouse model. Glab reduces OS-induced apoptosis in vitro and in vivo by enhancing antioxidant capacity and reducing inflammation.\n\nID: 42489267\nTitle: A Blood-Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN-Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1.\nAbstract: Peripheral factors that systemically regulate amyotrophic lateral sclerosis (ALS) have remained elusive-until now. Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n\nID: 42484074\nTitle: SOD1-lowering therapy for patients with wildtype SOD1-ALS: a case report.\nAbstract: Background and Objectives: To describe clinical and biomarker experience using an SOD1 antisense oligonucleotide (ASO) in a patient with non-SOD1 amyotrophic lateral sclerosis (ALS). Methods: Case report. Results: In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease. The time from symptom onset to death was 9\u2009months. Discussion: While treatment was initiated relatively late (\u223c7\u2009months) after symptom onset and follow-up duration was short, the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.\n\nID: 42480869\nTitle: Macrophage responses to and elevated antibody levels against Chlorovirus ATCV-1 in ALS patients.\nAbstract: Acanthocystis turfacea chlorella virus 1 (ATCV-1) is a giant virus that is part of the human oral microvirome. Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease.\n\nID: 42479071\nTitle: Effects of six weeks of hypoxia and hypoxic SIT on oxidative stress and myokine responses in skeletal muscle of high-fat-fed ApoE-/- mice.\nAbstract: Atherosclerosis-induced oxidative stress drives skeletal muscle myopathy in peripheral artery disease, yet the combined effects of hypoxia and hypoxia sprint interval training (SIT) remain unclear. The present study was designed to evaluate how a six-week regimen of hypoxia exposure and SIT influences redox balance and myokine production in the skeletal muscle of high-fat diet (HFD) (21% fat, 1.5% (w/w) cholesterol; 43% (w/w) sucrose-free carbohydrate, 4.554\u00a0kcal/g)-fed atherosclerotic ApoE-/- mice. Forty male ApoE-/- mice fed a HFD were randomly assigned to four groups: Control-Normoxia, Control-Hypoxia, SIT-Normoxia, and SIT-Hypoxia. The hypoxia protocol involved exposures to 11.2% oxygen three times (40\u00a0min each) per week. Key assessment parameters included plasma lipid profiles, skeletal muscle reactive oxygen species (ROS), protein carbonyls, key components of the Nrf2 antioxidant pathway, glutathione metabolism, and myokine-related markers. Compared with the control group, both hypoxia and SIT-Normoxia significantly reduced levels of ROS, protein carbonyls, and Vegfa165 mRNA expression in the skeletal muscle. Hypoxia alone enhanced the levels of GSH-synthesizing enzymes and promoted myokine production. SIT-Normoxia improved plasma lipid profiles, activated the Nrf2 pathway, enhanced the GSH system, and upregulated myokines. SIT under hypoxia further reduced ROS and Vegfa165 while increasing plasma HDL-C and levels of SOD1 protein in the skeletal muscle, but failed to synergistically activate the Nrf2 pathway or enhance GSH production. Paradoxically, both intervention combinations suppressed the mRNA expression of myokine precursor Fndc5, BAIBA-synthesizing enzyme Hadh and Hadha. Overall, six weeks of isolated hypoxia exposure or SIT training independently reduced oxidative stress and promoted beneficial myokine responses in the skeletal muscle of ApoE-/- mice fed a HFD. The wild-type (WT) mice fed a low-fat diet (LFD) was included to validate successful induction of hyperlipidemia, vascular remodeling, and skeletal muscle oxidative stress in ApoE-/- mice after six weeks of HFD feeding.\n\nID: 42469634\nTitle: Secretory leukocyte protease inhibitor (SLPI) attenuates TLR4/NF-\u03baB-mediated neuroinflammation in amyotrophic lateral sclerosis: a candidate molecule associated with neuro-pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons. While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.\n\nID: 42467070\nTitle: Pivotal Factors in Breast Cancer Molecular Subtypes Apoptosis Induction by ELF-EMF; Ki-67, ROS Level, HER-2, and SODs.\nAbstract: Although increasing research has shown that extremely low-frequency electromagnetic fields (ELF-EMFs) specifically trigger PCD through the elevation of ROS levels in cancer cells, there is no adequate evidence to determine the exact mechanisms of this phenomenon. The antioxidant machinery may play a crucial role in this area; however, this has been neglected in previous research. The main aim of this study was to assess the effect of ELF-EMF exposure (5\u2009days, 1\u2009Hz, 100\u2009mT, 2\u2009h/day) on ROS levels, expression levels of antioxidant genes, and apoptosis induction in different breast cancer molecular subtypes with different p53 statuses. DCFH-DA results revealed that the ROS level increased in all three cell lines (SKBR-3, MDA-MB-231, and MCF-7); this increase was much greater in SKBR-3 (up to 5-fold compared to its sham exposure). This result was concurrent with the annexin V/PI results; SKBR-3\u2009cells showed much more apoptosis induction (about 78%), compared with the others (22% or 11% in the other two cells). On the other hand, the mRNA expression level of SOD1 and SOD2 increased significantly in the MDA-MB-231, in addition to these two genes, the expression level of SOD3 and GSR increased in the MCF-7\u2009cells but not in the SKBR-3. Taken together, our results confirmed that ELF-EMF induced ROS-dependent apoptosis, especially in HER-2-enriched breast cancer cells (the SKBR-3), in a p53-independent manner. Other molecular subtypes (MDA-MB-231 as TNBC, or MCF-7 as luminal A) showed resistance against the ROS level increasing and subsequent apoptosis induction by using antioxidant genes, especially SOD1.\n\nID: 42465739\nTitle: Development and efficacy of ex vivo expanded autologous regulatory T cells for the treatment of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited therapeutic options, in which neuroinflammation critically drives disease progression. Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.\n\nID: 42458007\nTitle: Oligonucleotide-siRNA conjugate for SOD1 amyotrophic lateral sclerosis: a phase 1 trial.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease partly caused by gain-of-function mutations in superoxide dismutase 1 (SOD1). Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS. ClinicalTrials.gov registration: NCT05903690 .\n\nID: 42453524\nTitle: Therapeutic potential of adipose-derived stem cell transplantation in amyotrophic lateral sclerosis: A combined clinical case and preclinical study.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an inevitably fatal neurodegenerative disease with no adequate treatment. Transplantation of adipose-derived stem cells (ADSCs) may be an effective therapeutic strategy for delaying progression or restoring neurological function in ALS. We evaluated the safety and therapeutic efficacy of intravenous (i.v.) and intracerebral (i.c.) ADSC injection in a late-stage ALS patient and in a SOD1 transgenic (Tg) mouse model. Magnetic resonance imaging (MRI) and computed tomography (CT) were conducted to examine potential cerebral hemorrhage and tumor generation in the treated patient. In addition, maximal inspiratory pressure, maximal expiratory pressure, tidal volume, and respiratory rate were measured as indices of respiratory function. ADSC transplantation was safe, with MRI and CT showing no hemorrhage or tumorigenesis up to 12 months. The patient's Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score improved from 7 to 9 at 3 months and remained above baseline for 6 months. Respiratory function was preserved during this period. In SOD1 Tg mice, i.c. and i.v. ADSC infusion significantly prolonged survival (165.0 \u00b1 10.4 and 147.3 \u00b1 4.5 days vs. 129.7 \u00b1 3.9 days) and improved motor scores (P < 0.01). This preliminary finding suggests potential therapeutic feasibility, but further studies with larger cohorts are needed to confirm its safety and efficacy.\n\nID: 42450300\nTitle: Transcriptomic Profiling Reveals Inflammatory, Fibrotic, and Apoptotic Signatures in a Methionine-Choline-Deficient Diet-Induced Murine Model of Metabolism-Dysfunction-Associated Steatohepatitis.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH; formerly non-alcoholic steatohepatitis, NASH) is characterized by oxidative stress, inflammatory activation, hepatocellular injury, and progressive liver dysfunction. However, the global transcriptomic landscape underlying stress-induced hepatic injury remains incompletely understood. In this study, we employed a methionine-choline-deficient (MCD) diet-induced murine model to characterize the phenotypic and transcriptomic alterations associated with liver injury. Male C57BL/6J mice were fed either a control or MCD diet, and hepatotoxicity was assessed by survival analysis, body and liver weight measurements, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, histopathological examination, RNA sequencing, quantitative real-time PCR (qRT-PCR), and tumor necrosis factor-alpha (TNF-\u03b1) enzyme-linked immunosorbent assay (ELISA). MCD feeding markedly reduced survival and body weight while inducing hepatomegaly and significant elevations in serum ALT and AST, indicating severe hepatocellular injury. Histopathological analysis demonstrated hepatic steatosis, hepatocellular ballooning, and lobular inflammation without histological evidence of fibrosis. Transcriptomic profiling revealed extensive gene expression remodeling, characterized by activation of inflammatory pathways, enrichment of MAPK-related signaling, dysregulation of lipid metabolism, suppression of antioxidant defense systems, impairment of cytochrome P450-mediated detoxification, and upregulation of apoptosis-associated genes. qRT-PCR further validated the differential expression of representative genes involved in inflammatory signaling (Tlr4, Nfkb1, Nlrp3, and Casp1), MAPK signaling (Fos), xenobiotic metabolism (Cyp4f18), lipid metabolism (Apoa4 and Lpl), extracellular matrix remodeling (Mmp12), and oxidative stress responses (Sod1 and Gstp1). In addition, elevated serum TNF-\u03b1 levels provided protein-level evidence supporting activation of the TLR4/NF-\u03baB/TNF-\u03b1/NLRP3 inflammatory axis. Although fibrosis-associated transcriptional responses were detected, the absence of histological fibrosis suggests transcriptional priming of fibrogenic pathways rather than established fibrogenesis. Collectively, these findings provide a transcriptomic framework linking oxidative stress, impaired detoxification, inflammatory activation, and stress-responsive signaling to MCD-induced hepatic injury. The MCD model provides a valuable experimental platform for characterizing hepatic stress-response transcriptomes and for generating hypotheses that can subsequently be evaluated in environmentally relevant toxicological models. Nevertheless, caution should be exercised when extrapolating these findings to obesity-associated human MASLD, as the MCD model lacks key metabolic features of the human disease, including obesity and insulin resistance. Therefore, the present findings should be interpreted primarily as transcriptomic signatures of stress-induced hepatic injury rather than as a direct representation of the pathophysiological processes underlying human obesity-associated MASLD.\n\nID: 42450273\nTitle: Microvesicle-Derived Redox Signatures as Mediators of Endothelial Dysfunction in Diabetes.\nAbstract: Chronic hyperglycemia and excessive reactive oxygen species (ROS) production are defining features of endothelial dysfunction, a key driver of diabetic vascular complications such as diabetic nephropathy. Microvesicles (MV-enriched fraction), a subtype of extracellular vesicles, and the stress-responsive antioxidant protein Sestrin2 (SESN2) have emerged as important contributors to these processes. This study investigated the role of the MV-enriched fraction in endothelial cell communication under diabetic conditions, with a particular focus on oxidative stress signaling. To model diabetic injury, EA.hy926 endothelial cells were treated with methylglyoxal (MGO), and the resulting MV-enriched fraction was isolated and then applied to two recipient models: na\u00efve endothelial cells and SESN2 knockdown (KD) cells. Protein expression of key antioxidant markers, including endothelial nitric oxide synthase (eNOS), was assessed by Western blot. Nitric oxide (NO) bioavailability was quantified via nitrite measurement using 2,3-diaminonaphthalene (DAN), while mitochondrial and cytosolic ROS levels were evaluated using MitoSOX and dihydroethidium (DHE), respectively. Results demonstrated that the MV-enriched fraction derived from diabetic conditions triggers a complex antioxidant response in healthy endothelial cells, characterized by upregulation of SESN2, superoxide dismutase 1 (SOD1), and heme oxygenase-1 (HO-1). This suggests a compensatory mechanism that mitigates oxidative stress. Notably, SESN2 KD cells exhibited increased ROS production and reduced NO levels upon MV treatment, underscoring the essential role of SESN2 in maintaining redox homeostasis. Overall, this study highlights the dual role of the MV-enriched fraction as a mediator of both protective and detrimental redox signaling in diabetic endothelial dysfunction and suggests potential therapeutic targets for managing diabetic vascular complications.\n\nID: 42450113\nTitle: Serum Copper-to-Zinc Ratio and Oxidative Stress Are Associated with Anemia in Older Adults with Cardiovascular-Kidney-Metabolic Syndrome.\nAbstract: Chronic oxidative stress is a molecular hallmark of cardiovascular-kidney-metabolic (CKM) syndrome, yet its contribution to CKM-associated anemia beyond erythropoietin deficiency and iron restriction is poorly characterized. The serum copper-to-zinc (Cu/Zn) ratio reflects impaired Cu/Zn-SOD1 antioxidant capacity and inflammatory trace-element imbalance, but its relationships with circulating redox biomarkers and its hematological relevance in CKM syndrome has never been explored in a community-dwelling cohort of older adults. We analyzed 2391 NHANES 2011-2016 participants \u2265 50 years of age with CKM stage I-IV. To explore whether the serum Cu/Zn ratio was associated with oxidative stress and immunomodulatory biomarkers as well as with the odds of anemia, we used survey-weighted Spearman correlations, linear regression (outcome: hemoglobin), and logistic regression (outcome: anemia); multivariate models were adjusted for a panel of antioxidant or immunomodulatory biomarkers (selenium, vitamin D), pro-oxidant biomarkers (lead, cadmium, cotinine, uric acid), red cell distribution width (RDW) as a composite biomarker of erythrocyte stress, neutrophil-to-lymphocyte ratio (NLR), CKM stage, and comorbidities. The molecular targets of the nine biomarkers were mapped onto a protein-protein interaction network using the STRING database v12.0 to contextualize regression findings within a systems biology framework. Anemia was present in 205 participants (8.6%). The Cu/Zn ratio was inversely correlated with the antioxidant marker selenium (r = -0.19; p < 0.001) and positively correlated with the pro-oxidant markers RDW (r = +0.21; p < 0.001) and cadmium (r = +0.10; p < 0.001), consistent with its role as a hub within the CKM redox network. In fully adjusted models, a higher Cu/Zn ratio was independently associated with prevalent anemia (OR = 2.94; 95% CI: 1.61-5.37) and lower hemoglobin (\u03b2 = -0.55 g/dL); among included biomarkers, selenium and cadmium were independently protective (OR = 0.76 per 10 \u00b5g/L and 0.23 per \u00b5g/dL, respectively), and RDW and uric acid were independently harmful (OR = 2.20 per 1% and 1.33 per mg/dL, respectively). The Cu/Zn ratio correlated with both antioxidant depletion and pro-oxidant accumulation in CKM syndrome and was independently associated with anemia within this oxidative network. Together with selenium, cadmium, RDW, and uric acid, it defines an oxidative stress-driven hematological pathway that may contribute to the development and progression of anemia in patients with CKM syndrome.\n\nID: 42447970\nTitle: Human umbilical cord-derived mesenchymal stem cells ameliorate muscle dysfunction and metabolic dysregulation in the CuZnSOD null mouse model of sarcopenia.\nAbstract: Age-related sarcopenia is a progressive skeletal muscle disorder driven by oxidative stress and metabolic dysregulation. Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.\n\nID: 42447123\nTitle: Neuromuscular ultrasound as a biomarker in the SOD1 mouse model of amyotrophic lateral sclerosis.\nAbstract: A progression marker that indicates early disease-related changes and treatment responses in the to date incurable neurodegenerative disease amyotrophic lateral sclerosis (ALS) is highly desirable. Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.\n\nID: 42442802\nTitle: The Role of Genetic Alterations in the Emergence of Alzheimer's Disease in Down Syndrome: A Review.\nAbstract: Down syndrome (DS), the most common chromosomal disorder, is associated with an accelerated aging process, increasing the risk of early-onset Alzheimer's disease. This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers.\n\nID: 42442304\nTitle: Amelioration of obesity-induced testicular dysfunction and structural damage by ganoderma lucidum polysaccharides and triterpenoids in rats: Correlation with Nrf2-mediated antioxidant response.\nAbstract: Obesity is a global health crisis and a critical risk factor for male infertility, impairing testicular structure and function through hormonal imbalance and oxidative stress. Current therapeutic strategies are often unsatisfactory due to limited efficacy or adverse effects. This study investigated the protective effects and potential molecular mechanisms of Ganoderma lucidum (GL) polysaccharides and triterpenoids against testicular injury in high-fat diet-induced obese male rats. After 12-week GL intervention, reproductive function in obese male rats showed improvement: GL increased litter size, improved sperm motility, reduced sperm DNA fragmentation, and restored serum testosterone, inhibin B, and leptin levels. It also alleviated testicular histopathological damage, downregulated PPT1, and maintained vimentin expression. Notably, GL facilitated delayed fertility recovery and showed a trend toward improved cumulative reproductive success, although fixed-time pregnancy rates were not significantly changed. Mechanistically, GL is associated with enhanced Nrf2 pathway activity, increased SOD1, HO-1, NQO1, and GPX4 levels, and decreased MDA and ROS accumulation, thereby attenuating oxidative stress. It preserved mitochondrial integrity, suppressed germ cell apoptosis (downregulating Bax and caspase-3, upregulating Bcl-2), and promoted cell proliferation. These findings indicate that GL polysaccharides and triterpenoids effectively ameliorate obesity-induced testicular dysfunction, and these beneficial effects are associated with Nrf2-mediated antioxidant responses, mitochondrial homeostasis, apoptosis regulation, and hormonal balance. GL may serve as a promising candidate for obesity-related male infertility.\n\nID: 42437952\nTitle: NOP56 is essential for mammalian generation and maintenance of multiple central nervous systems, associated with SCA36 pathology.\nAbstract: NOP56, a core nucleolar component involved in small nucleolar ribonucleoprotein assembly, has been genetically implicated in spinocerebellar ataxia type 36. However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097.\n\nID: 42432986\nTitle: Mitoquinone Prevents Cardiac Dysfunction by Normalizing Mitochondrial ROS and Calcium Handling in Acute Myocardial Infarction.\nAbstract: Acute myocardial infarction (MI) is the leading cause of heart failure (HF). However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI. Male Wistar rats were divided into four experimental groups: Sham, Infarct, Sham+MitoQ, and Infarct+MitoQ. MitoQ was administered orally (8\u2009mg/kg/dia) for 7\u2009days. Hemodynamic parameters, infarct area, papillary muscle contractility, cardiomyocyte mechanics, Ca2+ transients, and total and mitochondrial superoxide (DHE and MitoSOX) were assessed. After 7\u2009days of MI, rats exhibited impaired contractility, altered inotropic response to extracellular Ca2+, cardiomyocyte hypertrophy, and increased total and ROSm. MitoQ prevented body weight loss and significantly improved hemodynamic parameters compared to the Infarct group. In papillary muscles, MitoQ restored basal isometric force and the inotropic response to extracellular Ca2+. In cardiomyocytes, it attenuated hypertrophy, preserved shortening, and reduced ([Ca2+]i) transient amplitude. MitoQ significantly decreased total and mitochondrial O2\u2022- production. It selectively reduced NOX1 expression under simulated conditions but did not significantly affect NOX2, SOD1, or catalase expression in the context of MI. MitoQ prevented contractile dysfunction, suggesting that mitochondrial oxidative stress plays a decisive role in myocardial dysfunction during the acute phase of MI. Targeting antioxidant therapy to the mitochondria represents a promising strategy for preventing post-infarction heart failure and opens new perspectives for the development of more effective interventions in the treatment of cardiovascular diseases.\n\nID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the \u03b11 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.\n\nID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.\n\nID: 42425334\nTitle: Comparative screening of Amur tiger cytokines identifies IL-15 as a cytoprotective candidate against feline panleukopenia virus infection.\nAbstract: Comparative studies of species-derived cytokines remain limited in endangered carnivores. We cloned six immune-related cytokines from Amur tigers (Panthera tigris altaica), with sequence analysis revealing >90% identity across Felidae. Among all tested cytokines, IL-15 demonstrated superior and sustained lymphocyte-stimulatory activity at 200\u202fng/mL. To investigate antiviral potential, F81\u202fcells were pretreated with IL-15 and challenged with feline panleukopenia virus (FPV). Mechanistic studies revealed that IL-15 attenuated virus-induced apoptosis by modulating key regulatory proteins: downregulating pro-apoptotic factors (Bax, Caspase3/9, p53, Cytc) while upregulating anti-apoptotic Bcl-2. Additionally, IL-15 preserved mitochondrial integrity by maintaining membrane potential, enhancing fusion proteins (MFN1/MFN2), and suppressing fission protein Drp1. IL-15 also strengthened cellular antioxidant defenses through increased SOD1/SOD2 expression, significantly reducing reactive oxygen species (ROS) accumulation. These protective effects persisted for 48\u202fh post-infection, demonstrating sustained cytoprotective effects. These findings reveal species-specific IL-15-mediated antiviral mechanisms within the Felidae family and provide comparative insights into how immune defenses are optimized in species with constrained evolutionary history, with implications for understanding carnivore immune evolution and conservation medicine.\n\nID: 42419058\nTitle: Redox Imbalance and Impaired Protein Clearance Drive Chronic Liver Injury in Biliary Atresia.\nAbstract: Excessive or uncontrolled generation of reactive oxygen species (ROS) is closely associated with the development of liver diseases. However, direct evidence linking oxidative stress to impaired hepatic function in human biliary atresia (BA) remains limited. To address this, we performed bulk RNA sequencing to investigate (1) alterations in hepatic oxidative stress and antioxidant defense mechanisms and (2) transcriptomic changes associated with impaired hepatic function in BA. Total RNA was extracted from liver samples of patients with BA and non-BA cholestasis. Bulk RNA sequencing and transcriptomic analyses were performed, focusing on redox-related pathways and genes linked to hepatic function. Dual oxidases 1 and 2 were significantly upregulated in BA. In contrast, key ROS-metabolizing enzymes such as catalase, glutathione synthetase, and superoxide dismutase 1 and 2 were downregulated, indicating redox imbalance in BA livers. Excessive ROS can lead to the denaturation of cellular proteins and damage to organelles, which are normally degraded via autophagy and proteasomes. However, both autophagy and proteasome functions were impaired in BA, contributing to sustained inflammation and further ROS production. Transcriptomic analyses also revealed repression of core liver transcription and splicing factors, indicating injury-associated alterations in hepatic transcription programs. BA is characterized by a redox imbalance and dysfunctional protein clearance, forming a vicious cycle of ROS accumulation and inflammation. These changes likely contribute to liver fibrosis and the progressive loss of hepatic function in BA.\n\nID: 42410102\nTitle: A changed landscape: five-year retrospective on the paradigm shift in genetic testing practices for ALS in Canada.\nAbstract: Offering genetic testing is increasingly recommended for all individuals with amyotrophic lateral sclerosis (ALS), particularly following the development of gene-targeted therapies, such as tofersen for SOD1-ALS. Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards.\n\nID: 42406382\nTitle: Antisense Oligonucleotide Tofersen Distribution in the Central Nervous System of SOD1-ALS Autopsy Tissue Donors.\nAbstract: Tofersen is a disease-modifying antisense oligonucleotide therapeutic for people living with SOD1-amyotrophic lateral sclerosis (SOD1-ALS). Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues.\n\nID: 42402967\nTitle: Hypoxia-preconditioned dental pulp stem cells alleviate acetaminophen-induced liver failure via promoting MYC-HIF1A/HIF-1\u03b1-BNIP3-mediated mitophagy.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is a prevalent clinical liver condition caused mostly by oxidative stress and mitochondrial damage. Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot.\n\nID: 42399593\nTitle: Early and severe masticatory muscle involvement in SOD1-ALS: a case report with biomarker-clinical dissociation.\nAbstract: \n\nID: 42483815\nTitle: Synergistic regulation of abiotic stress adaptation by copper miRNAs miR398 and miR408 in melon.\nAbstract: MicroRNAs (miRNAs) in general and miR398 and miR408 in particular have emerged as key regulators of plant adaptation to individual stress, yet their roles regulating the crop response to diverse unfavorable environments remain poorly explored. Here, we report transgenic melon (Cucumis melo) plants overexpressing miR398 and miR408 precursors, two conserved miRNAs involved in copper-related regulatory pathways and associated with stress response. Engineered plants exhibited enhanced vegetative development, including stem elongation, internode formation, root architecture, and leaf production. The significant increased accumulation of well-processed miR398 and miR408, along with the downregulation of their respective targets (Copper/Zinc Superoxide Dismutase and Basic Blue Protein) demonstrates the functional activity of the transgenes. Sequencing analysis revealed a positive correlation in the accumulation of miR398 and miR408, suggesting a coordinated accumulation pattern with interdependent miRNA regulation, potentially independent of conventional transcription factor activity. Transgenic plants showed improved tolerance to drought, salinity, heat, and cold stress, validating the role of miR398 and miR408 as master regulators of abiotic stress resilience in melon. This work highlights the potential of biotechnological strategies based on engineering Cu-related miRNAs to enhance crop performance under different adverse environments, thereby contributing to agricultural sustainability in the face of climate change.\n\nID: 42471086\nTitle: Contrasting effects of short- and long-term starvation on intestinal health and gut microbiome in yellow cheek carp (Elopichthys bambusa).\nAbstract: Starvation is a common stressor in aquaculture that can markedly affect intestinal health and function in fish. This study focused on yellow cheek carp (Elopichthys bambusa, initial body weight: 221.36\u00a0\u00b1\u00a06.75\u00a0g; initial body length: 28.47\u00a0\u00b1\u00a00.56\u00a0cm) to explore how short-term (8\u00a0days) and long-term (28\u00a0days) starvation influence intestinal morphology, expression of key functional genes, and gut microbiota composition. Additionally, Spearman's rank correlation analyses were conducted to explore potential host-microbe interactions. The results showed that short-term starvation did not significantly affect intestinal muscle layer thickness or villus height, but markedly upregulated genes associated with autophagy and apoptosis such as bcl-2-associated X protein 2 (bax2), bcl-2-like protein 1 (bcl2l1), and cysteine-aspartic acid protease 8(casp8). It also increased microbial diversity and altered the composition of dominant gut microbiota. In contrast, long-term starvation significantly suppressed the expression of copper/zinc superoxide dismutase (Cu-Zn sod), casp3a, and casp9, increased the number of goblet cells, inhibited muscle layer development, and weakened the correlation between gut microbes and host gene expression. In summary, short-term starvation appears to maintain intestinal homeostasis through activation of autophagy- and apoptosis-related pathways in conjunction with microbial restructuring. However, prolonged starvation inhibited muscularis development, increased goblet cell density, downregulated antioxidant and immune-related gene expression, and weakened the associations between the host and its microbiota. These findings provide new insights into starvation-induced physiological responses and contribute to gut health management strategies in aquaculture.\n\nID: 42449057\nTitle: Ficus deltoidea Preserves Hippocampal Neuronal Integrity and Redox Balance in Oxidative Stress-Driven Alzheimer's Disease-Like Rat Model.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the leading cause of dementia worldwide, with oxidative stress playing a central role in its pathogenesis. Ficus deltoidea (FD), a medicinal plant rich in flavonoids vitexin and isovitexin, possesses potent antioxidant and anti-inflammatory properties, yet its neuroprotective efficacy in AD remains incompletely characterized. This study investigated the protective effects of FD in a D-galactose- and aluminum chloride (AlCl3)-induced oxidative stress-driven AD-like rat model using behavioral, histological, ultrastructural, and biochemical approaches. Fifty-four male Wistar rats were assigned to six groups: control, AD-like model, donepezil (1\u00a0mg/kg), and FD-treated groups (50, 100, and 200\u00a0mg/kg) for 10\u00a0weeks. Anxiety-like behavior and spatial working memory were assessed using the elevated plus maze (EPM) and T-maze tests, respectively. Hippocampal neuronal integrity was evaluated by hematoxylin and eosin (H&E) staining and transmission electron microscopy (TEM), while oxidative stress biomarkers (MDA, CAT, T-SOD, CuZn-SOD, and HO-1) were quantified using ELISA. FD treatment, particularly at 200\u00a0mg/kg, significantly improved spatial working memory and normalized anxiety-related behavior, with treatment responses approaching those observed in the donepezil-treated group. Histological analyses revealed preservation of pyramidal neurons across CA1, CA2, CA3, and dentate gyrus subregions, while ultrastructural studies demonstrated marked protection of mitochondrial integrity, myelin sheath organization, and smooth endoplasmic reticulum morphology. Biochemically, FD significantly reduced lipid peroxidation and enhanced endogenous antioxidant defenses. In conclusion, FD exerted significant neuroprotective effects characterized by preservation of hippocampal structure, maintenance of neuronal ultrastructure, and restoration of redox homeostasis in an oxidative stress-driven AD-like model. These findings demonstrate that FD mitigates oxidative stress-associated neuronal injury and cognitive impairment in a D-galactose and AlCl3-induced AD-like rat model, supporting its potential as a phytotherapeutic candidate for oxidative stress-related neurodegeneration. However, further studies are required to determine its effects on canonical Alzheimer's disease pathologies, including amyloid and tau abnormalities.\n\nID: 42437042\nTitle: Effects of waterborne cadmium exposure on hematological parameters, oxidative stress, and stress-related genes in crucian carp (Carassius auratus).\nAbstract: Cadmium (Cd) is a non-essential and highly toxic heavy metal widely present in aquatic environments. However, studies investigating the toxic effects of Cd on crucian carp (Carassius auratus) are relatively few. This study aimed to evaluate the toxic effects of Cd by assessing hematological parameters, antioxidant responses, and the expression of stress-related genes in C.\u00a0auratus exposed to waterborne Cd. A total of 180 healthy C.\u00a0auratus (19.43 \u00b1\u00a01.5 cm and 170.00 \u00b1\u00a03.04 g) were exposed to Cd at concentrations of 0, 2, and 4 mg/L for 8 weeks, with three replicates per treatment. The exposure to Cd resulted in significant reductions in red blood cell (RBC) count, hemoglobin (Hb) concentration, and hematocrit (Hct) values. Moreover, the levels of total superoxide dismutase (T-SOD), catalase (CAT), and glutathione peroxidase (GPx) in the liver also decreased significantly, whereas malondialdehyde (MDA) content was increased significantly. The expression levels of CAT, copper (Cu)/zinc (Zn)-superoxide dismutase (Cu/Zn-SOD), heat shock protein 70 (HSP70), heat shock protein 90 (HSP90), and metallothionein (MT2) genes were significantly upregulated. Overall, Cd exposure adversely affected the hematological parameters, induced oxidative stress, and altered the expression levels of stress-related genes. This study not only provides new insights into the toxic effects of Cd in C. auratus but also contributes to environmental monitoring research.\n\nID: 42436339\nTitle: Integrating morphophysiology, gene expression and machine learning to characterize salt and drought stress responses in dragon fruit.\nAbstract: Abiotic stresses are major environmental constraints that limit plant growth and productivity, particularly in arid and semi-arid regions where salinity and drought frequently occur simultaneously. In this study, the effects of salt stress (150 mM NaCl), PEG-induced drought stress (4% PEG-8000), and their combined application on the in vitro responses of dragon fruit (Hylocereus undatus) were evaluated at morphophysiological, molecular, and machine learning levels. The selected NaCl and PEG concentrations were used to impose moderate-to-severe salinity and osmotic stress conditions previously reported to affect pitaya growth and physiology. Cladode explants were exposed to stress treatments for 14 days, after which visual stress score, lateral shoot number, stem length, root length, stem diameter, fresh weight, dry weight, root number, and SPAD value were measured. In addition, the expression levels of five stress-responsive genes (HuERF1, HuTZF3, Cu/Zn-SOD, CAT, and NCED) were analyzed using RT-qPCR. Salt stress and, more prominently, the combined salt-drought treatment markedly impaired plant growth and physiological performance. Compared with the control, the combined treatment reduced root length by approximately 87%, fresh weight by 67%, root number by 54%, and SPAD value by 46%, indicating severe inhibition of root development, biomass accumulation, and chlorophyll-related performance. Gene expression analysis revealed strong induction of HuERF1 and Cu/Zn-SOD under salt-containing treatments, suggesting activation of stress-signaling and antioxidant defense responses, whereas NCED showed the highest upregulation under PEG-induced osmotic stress and combined stress, indicating the involvement of ABA-mediated osmotic adjustment. In contrast, CAT expression remained relatively stable across treatments. Morphological data were further analyzed using a Random Forest classifier, which distinguished stress treatments with an overall accuracy of approximately 73%. Feature importance analysis identified SPAD value, visual stress score, lateral shoot number, root number, and fresh weight as the most informative morphophysiological variables for treatment discrimination. Overall, these results demonstrate that salinity and drought, especially in combination, substantially affect growth performance and stress-responsive gene regulation in H. undatus, and highlight the potential of machine learning for identifying phenotypic signatures associated with abiotic stress responses.\n\nID: 42435233\nTitle: Transcriptomic Profiling Identifies Key Genes and Pathways Involved in the Abiotic Stress Response of Trichoderma viride.\nAbstract: Trichoderma is a filamentous fungus with substantial industrial and agricultural value; however, its practical application is constrained by abiotic stresses such as drought, high temperatures, and salinity, particularly when these stresses occur simultaneously. The molecular mechanisms underlying the responses of Trichoderma to combined abiotic stresses remain insufficiently understood. In this study, the stress-tolerant Trichoderma viride strain Tv-1511 was analyzed using RNA sequencing to characterize its transcriptomic responses under PEG-simulated drought stress, and the resulting data were integrated with previously generated transcriptomic datasets from high-temperature (42\u00a0\u00b0C, 24\u00a0h) and salinity (300 mmol/L NaCl, 72\u00a0h) treatments. Under 50% Polyethylene glycol (PEG)-simulated drought, 4510 differentially expressed genes were identified and enriched in secondary metabolite biosynthesis and \u03b2-lactam antibiotic synthesis based on Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. Integrating these drought stress data with the high-temperature and salinity datasets revealed 36 commonly upregulated and 29 commonly downregulated genes across triple stresses, primarily involved in redox processes and secondary metabolite synthesis. RT-qPCR validation indicated that Trichoderma mounts a synergistic response to multiple stresses by activating genes like MET17, ALDH (aminoglycoside synthesis), and FeSOD, Cu/ZnSOD, GCLC, GLO1, GST. These findings elucidate key transcriptomic mechanisms underlying Trichoderma responses to single and combined abiotic stresses and provide a theoretical foundation for the targeted improvement of stress-tolerant strains to enhance their agricultural and industrial utility.\n\nID: 42410741\nTitle: In Vitro Skin-Protective Effects of Sumyong Nature, a Kimchi- and Soybean-Derived Fusion-Fermented Microbial Supernatant, in Human Keratinocytes: Involvement of MAPK-Related Signaling.\nAbstract: Sumyong Nature (SN) is a kimchi- and soybean-derived fusion-fermented microbial supernatant prepared from Lactobacillus acidophilus, Saccharomyces cerevisiae, Weissella cibaria, and Bifidobacterium longum. This study examined the in vitro effects of SN on UVB-induced damage and skin-related cellular responses in human keratinocytes. Cell viability assays, gene expression analysis, luciferase reporter assays, immunoblotting, scratch wound-healing assays, and LC-Q-TOF-MS analysis were conducted. SN showed no significant cytotoxicity in HaCaT or HEK293T cells at concentrations up to 75 \u03bcg/mL. In UVB-irradiated HaCaT cells, SN improved cell viability, suppressed MMP-1 expression, increased HAS-1 expression, and modulated UVB-responsive stress-related markers, including SOD-1, Nrf2, and HO-1. SN also promoted wound closure in keratinocytes and was associated with changes in NF-\u03baB-, AP-1-, CREB-, and MAPK-related signaling responses under the tested conditions. LC-Q-TOF-MS analysis tentatively identified several candidate constituents, including pectolinarin and aloeresin-related compounds. Collectively, these findings suggest that SN exerts multiple beneficial in vitro effects in keratinocyte-based assays, warranting further mechanistic investigation and validation in advanced experimental models.\n\nID: 42490652\nTitle: A cost-optimized 5-protein panel revolutionizes systemic lupus erythematosus diagnosis.\nAbstract: Early diagnosis of systemic lupus erythematosus (SLE) is hindered by a lack of reliable biomarkers. This study sought to identify and evaluate diagnostic plasma protein biomarkers for SLE. We analyzed plasma protein profiles, polygenic risk scores (PRS), and clinical data from 544 SLE cases and 48,036 controls in the UK Biobank. Using LASSO regression, we identified 35 high-confidence SLE-associated proteins and derived a protein risk score (ProtRS). The ProtRS model achieved exceptional diagnostic performance (AUC\u2009=\u20090.91), significantly outperforming models based on PRS or clinical factors alone. Notably, a cost-optimized 5-protein panel (TRIM21, SOD2, KLK3, IL15, ADIPOQ) retained high accuracy (AUC\u2009=\u20090.82) while reducing costs by ~87%. ProtRS also demonstrated the highest population attributable fraction (96.34%), underscoring its dominant contribution to SLE burden. This study establishes a protein-driven framework for early SLE detection, offering tiered diagnostic solutions to balance accuracy and cost. The findings underscore the translational potential of protein biomarkers in bridging theoretical research and clinical practice.\n\nID: 42489973\nTitle: Gamete co-incubation duration modulates blastocyst developmental competence in buffalo through regulation of growth factors, steroidogenesis and oxidative stress pathways.\nAbstract: Gamete (sperm-oocyte) co-incubation duration during in vitro fertilization (IVF) is a key determinant of embryo developmental competence in buffalo. This study evaluated the effect of gamete co-incubation duration (2-h intervals from 2 to 24\u00a0h) on embryo development and blastocyst competence. A total of 3680 cumulus-oocyte complexes (COCs) were recovered from 1163 buffalo ovaries. Grade A and B COCs (n\u2009=\u20092390) were matured in vitro, and 2324 matured oocytes were subjected to IVF using different gamete co-incubation durations, followed by culture of 2012 presumptive embryos for 7 days. Cleavage, blastocyst development, and developmental competence were assessed using RT-qPCR. Cleavage rate was significantly affected (P\u2009<\u20090.05), increasing from 65.2% at 2\u00a0h to 100% at 8\u00a0h and remaining comparable between 10 and 24\u00a0h (81.7-97.1%). Blastocyst development increased progressively, reaching the highest rates at 16-20\u00a0h (53.2-54.9%; P\u2009>\u20090.05), before declining significantly at 22\u00a0h (32.7%) and 24\u00a0h (28.0%). Embryonic arrest was significantly lower in the 16-20\u00a0h groups. Blastocysts produced after 16-20\u00a0h exhibited higher (P\u2009<\u20090.05) expression of HSPB1, SOD2, GPX3, GDF9, BMP15, STAR, and BCL2, with lower BAX and CASP3 expression, indicating enhanced developmental competence. Although blastocysts developed following as little as 2\u00a0h of gamete co-incubation, a duration of 16\u00a0h produced outcomes comparable to the conventional 20-h protocol. Therefore, 16-20\u00a0h represents the optimal gamete co-incubation window for maximizing blastocyst yield and developmental competence in buffalo IVF.\n\nID: 42489248\nTitle: Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke-Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling.\nAbstract: Ischemic stroke induces oxidative stress, neuroinflammation, neuronal death, and synaptic dysfunction, leading to persistent motor and cognitive deficits. The human dental pulp stem cell (hDPSC) secretome is a promising cell-free therapeutic candidate containing neurotrophic, antioxidant, and immunomodulatory factors. Here, we investigated its therapeutic effects in a photothrombotic mouse model of ischemic stroke and CoCl2-induced hypoxic BV2 microglial cells. Proteomic profiling identified antioxidant-associated proteins, including SOD2, GSR, and GSTP1, and microglial phenotype-related candidates, including GRN, CSF1, and LRP1. hDPSC secretome treatment reduced stroke-induced infarct volume and attenuated stroke-increased neuronal apoptosis, neuronal ROS accumulation, and NF-\u03baB-associated inflammatory signaling in the cortex and hippocampus. It also shifted microglial marker expression toward an M2-associated profile and improved stroke-impaired hippocampal neurogenesis, vascular remodeling, and synaptic organization. Proteomic analyses further identified coordinated changes in pathways related to oxidative phosphorylation, inflammatory responses, calcium signaling, SNARE-associated vesicular transport, and ROBO-Rho-associated cytoskeletal remodeling. These molecular and cellular changes were associated with improved motor coordination, spatial learning and memory, contextual memory, and anxiety-like behavior. These findings support the hDPSC secretome as a cell-free therapeutic candidate for post-stroke functional recovery linked to redox, inflammatory, neurovascular, and synaptic remodeling.\n\nID: 42488660\nTitle: SIRT3 in post-myocardial infarction macrophage reprogramming: linking mitochondrial fitness to inflammation resolution and repair.\nAbstract: Myocardial infarction (MI) remains a leading cause of cardiovascular mortality worldwide. Despite significant advances in reperfusion strategies and pharmacotherapy, persistent inflammation and adverse ventricular remodeling continue to underlie poor long-term clinical outcomes. Macrophages serve as central orchestrators of post-MI healing, coordinating the clearance of necrotic debris, resolution of inflammation, remodeling of the extracellular matrix, and maturation of the fibrotic scar. However, the conventional M1/M2 dichotomy fails to fully capture the dynamic, phenotypically heterogeneous, and metabolically constrained macrophage states that emerge during infarct healing. In this review, we synthesize current evidence supporting a trajectory-based framework for macrophage reprogramming following MI and emphasize mitochondrial fitness as a critical determinant governing the transition from sustained inflammation to reparative resolution. We summarize key metabolic checkpoints regulating this functional shift-including glycolytic rewiring, tricarboxylic acid (TCA) cycle remodeling, mitochondrial reactive oxygen species (mtROS) accumulation, efferocytosis, oxidative phosphorylation (OXPHOS), fatty acid oxidation (FAO), and mitochondrial quality control. Furthermore, we advance the hypothesis that SIRT3-the principal mitochondrial NAD+-dependent deacetylase-may act as a central regulatory node linking mitochondrial protein acetylation to macrophage state transitions after MI. Specifically, we outline a staged dual-axis working model, generated from convergent but largely indirect evidence, in which the SOD2-mtROS axis is more closely linked to early nonresolving inflammation, whereas the PDHA1-metabolic flexibility axis may be more relevant to efferocytosis-associated reparative transition. We further highlight NAD+ availability as an upstream limiting factor that may constrain SIRT3 activity in macrophages under ischemic-inflammatory stress. Finally, we critically evaluate the current evidence hierarchy, human translatability, therapeutic strategies, and key translational challenges-emphasizing considerations of timing, cellular specificity, delivery modalities, and target engagement. Although macrophage-specific causal evidence in myocardial infarction (MI) remains sparse, this framework is intended as a mechanistically coherent and experimentally tractable working hypothesis to guide future investigations into macrophage immunometabolism and mitochondrial-targeted interventions in post-infarction cardiac repair. Accordingly, the proposed framework should be viewed as a testable working hypothesis rather than a settled causal model of macrophage fate control in MI.\n\nID: 42482529\nTitle: Single Cell RNA Sequencing Reveals THBS1+CD14+ Monocyte Modulates Inflammatory Activation via NRLP3-Inflammasome in Congenital Heart Block.\nAbstract: Isolated congenital heart block (iCHB) is defined as atrioventricular block without structural cardiac defects, characterized by irreversible fibrosis of the cardiac conduction system. Maternal autoantibodies may elicit systemic exaggerated immune responses involving type I interferon (IFN) signalling cascade, yet peripheral circulating immunity in CHB pathogenesis remains poorly understood. To investigate this, we performed single-cell RNA sequencing (scRNA-seq), followed by differential expression gene (DEG) analysis, SCENIC analysis, pseudotime analysis and cell communication analysis, to characterize systemic immune alterations in foetuses with CHB treated with dexamethasone and validated key findings by real-time quantitative PCR (qPCR) and flow cytometry. Compared with controls, CHB foetuses exhibited a markedly activated inflammatory response involving both IFN and NF-\u03baB pathways. Although monocytes showed significant changes in cellular proportions, upregulated DEGs and interferon-stimulated genes, prioritized cellular responses and enhanced intercellular interactions. Notably, THBS1+CD14+ monocytes had a pro-inflammatory phenotype with upregulated NLRP3 inflammasome-related genes and maturation toward a pro-inflammatory state, and Thbs1 conditional knockout mice showed reduced IL-1\u03b2 levels in BMDMs. Additionally, dexamethasone-treated monocytes had downregulated SOD2 (anti-apoptotic) levels compared to controls, confirmed by qPCR, and flow cytometry verified that dexamethasone promoted monocyte apoptosis. In conclusion, the peripheral immune system in CHB is characterized by innate immune activation driven mainly by monocytes, along with systemic inflammation including IFN signalling. THBS1+/CD14+ monocytes represent a distinct proinflammatory phenotype potentially linked to NLRP3-mediated inflammatory responses.\n\nID: 42470940\nTitle: Proteomic and amino acid profiling of SK-MEL-30 melanoma reveals metabolic and structural changes.\nAbstract: Melanoma exhibits high metastatic potential and therapy resistance, driven by metabolic flexibility and structural remodeling. In this study, we performed an integrated analysis of the SK-MEL-30 melanoma cell line using function-focused quantitative proteomics and amino acid profiling. Proteins were quantified using a label-free normalized spectral abundance factor (NSAF) approach, while intracellular amino acids were measured by LC-MS/MS. Functional enrichment analyses based on KEGG and Gene Ontology were used to associate protein expression patterns with metabolic pathways. A total of 148 proteins were identified, predominantly representing high-abundance and functionally relevant components of metabolic and structural pathways. Key cytoskeletal proteins, including vimentin and S100A11, were among the most abundant, consistent with a mesenchymal-like and potentially invasive phenotype. Metabolic profiling revealed elevated expression of glycolytic enzymes such as PKM and LDHA, consistent with a glycolytic shift. Increased levels of l-glutamine and l-glutamic acid, together with GOT2 expression, suggest an active glutamine aspartate axis supporting tricarboxylic acid cycle activity and nitrogen metabolism. In addition, elevated levels of stress-response proteins, including HSP90 and SOD2, indicate a proteostatic network adapted to metabolic stress. Although the proteome coverage is lower than that reported in large-scale deep proteomic studies, the NSAF-based workflow was designed to capture the most abundant and functionally relevant proteins, providing a focused overview of the major metabolic and structural characteristics of SK-MEL-30 melanoma cells. Overall, this integrative analysis highlights the coordination between metabolic reprogramming and cytoskeletal organization in SK-MEL-30\u202fcells and suggests that glutamine-dependent metabolic pathways warrant further investigation as potential therapeutic targets in melanoma.\n\nID: 42464732\nTitle: Ferroptosis-Mediated Placental Dysfunction in the Pathophysiology of Gestational Diabetes Mellitus.\nAbstract: Gestational diabetes mellitus (GDM) is a common metabolic complication of pregnancy associated with adverse maternal and fetal outcomes. Nevertheless, the molecular mechanism of placental dysfunction in GDM are still not clear, especially the role of ferroptosis and its interplay with oxidative stress, inflammation, and angiogenesis. Placental tissues from GDM pregnancies were examined to assess oxidative stress, antioxidant defense, ferroptosis regulation, inflammatory signaling, and angiogenic pathways. Expression levels of key molecular markers were evaluated, and correlation analyses were performed to identify mechanistic interrelationships. GDM placenta demonstrated elevated oxidative stress markers, including P22PHOX and TXNIP, accompanied by reduced antioxidant markers, such as HO-1, NQO1, SOD2, and CAT, indicating impaired cellular defense. Ferroptosis regulation was disrupted, as anti-ferroptotic markers GPX4, SLC7A11, and NRF2 were significantly downregulated, while pro-ferroptotic markers TFR1 and ACSL4 were increased, suggesting enhanced iron accumulation and lipid peroxidation. This was accompanied by heightened inflammation, evidenced by increased IL-6, IL-1\u03b2, TNF-\u03b1, and NF-\u03baB activation, alongside reduced IL-10 expression. Furthermore, angiogenesis was impaired, reflected by decreased VEGFA, HIF-1\u03b1, and SDF-1\u03b1 levels, highlighting poor vascular development in the placenta. Additionally, Correlation analyses demonstrated strong associations between ferroptosis markers and oxidative stress, inflammatory, and angiogenic pathways, suggesting the possible presence of an interconnected regulatory network. These findings identify ferroptosis as a central regulator of GDM-associated placental dysfunction, through a possible interconnected network of oxidative stress, inflammation, and impaired angiogenesis. Targeting ferroptosis may offer a possible therapeutic option to restore placental function and improve maternal-fetal outcomes in GDM.\n\nID: 42463033\nTitle: Protective effects of electrospun PVP nanofibers incorporating Polygonum cognatum extract in skin cells under hypoxic conditions: Anti-inflammatory, antioxidant, and antibacterial surface functionality.\nAbstract: In this study, PVP nanofibers loaded with Polygonum cognatum (madimak) extract (PVP-F\u00a0+\u00a0ME) and pure PVP nanofibers (PVP-F) were developed to evaluate their biological effects on HDFa cells under a CoCl\u2082-induced hypoxia-like model. The nanofibers were fabricated by electrospinning and characterized by FTIR and SEM, confirming successful incorporation of the extract and morphological changes in fiber structure. MTT and LDH assays showed that both formulations maintained cell viability under oxidative stress, while scratch assays indicated enhanced fibroblast migration. RT-qPCR results demonstrated that PVP-F\u00a0+\u00a0ME significantly downregulated CoCl\u2082-induced expression of HIF-1\u03b1, IL-1\u03b2, IL-6, and TNF-\u03b1, and normalized antioxidant-related genes such as SOD2 and GPx. Antibacterial testing revealed selective activity against Gram-positive bacteria (Staphylococcus aureus and Enterococcus faecalis). Overall, the findings suggest that PVP-based nanofibers, particularly when enriched with madimak extract, provide protective, anti-inflammatory, and antimicrobial effects with potential applications in wound healing.\n\nID: 42462996\nTitle: Comprehensive analysis of the association between perfluorooctanoic acid exposure and osteosarcoma progression.\nAbstract: Perfluorooctanoic acid (PFOA), a persistent environmental pollutant, represents a chronic environmental stressor, yet its role in osteosarcoma progression remains unclear. Here, we integrated network toxicology, machine learning, immune infiltration analysis, single-cell RNA sequencing, molecular docking, molecular dynamics simulation, and in vitro assays to define the mechanisms linking long-term PFOA exposure to osteosarcoma. We identified 28 shared targets between PFOA-associated proteins and osteosarcoma-related genes, which were mainly enriched in oxidative stress, immune regulation, and metabolic reprogramming pathways. Machine learning prioritized nine candidate hub genes, including PNP, SOD2, MAT1A, RELA, PSAT1, CXCL12, PHGDH, PDK4, and CFD, with PHGDH, PSAT1, PDK4, and MAT1A suggesting a metabolism-related axis relevant to PFOA-associated osteosarcoma alterations. Single-cell and immune analyses showed distinct cell-type-specific expression patterns of these genes and their close associations with the tumor immune microenvironment. Molecular docking and molecular dynamics simulations further suggested potential structural compatibility between PFOA and several prioritized hub proteins. Experimentally, prolonged exposure to non-cytotoxic concentrations of PFOA enhanced osteosarcoma cell proliferation and invasion, whereas high concentrations were cytotoxic. Collectively, these findings suggest that long-term PFOA exposure may promote osteosarcoma progression by coupling environmental stress with metabolic reprogramming and immune dysregulation.\n\nID: 42457094\nTitle: Ergothioneine attenuates cardiac fibrosis induced by a high-fat diet in spontaneously hypertensive rats.\nAbstract: Ergothioneine (ERG) is a dietary thiol that is selectively accumulated in mammalian tissues via a specific transporter and may protect the cells against oxidative and inflammatory burden. In this study, we investigated the protective effects of ERG on high-fat diet (HFD)-induced cardiac fibrosis in the spontaneously hypertensive rats (SHR). ERG treatment (50 mg/kg daily, for 10 weeks) attenuated cardiac remodelling, as evidenced by reduced levels of the fibrosis markers hydroxyproline, \u03b1-smooth muscle actin, and galectin-3 increased by HFD. HFD induced obesity and altered plasma concentrations of metabolic hormones (thyroxine, leptin, and FGF21) and these changes were not affected by ERG. ERG suppressed SMAD-2 expression, indicating inhibition of TGF\u03b2-driven profibrotic signalling, and favourably modulated extracellular matrix composition by reducing the collagen I content as well as the collagen I/collagen III ratio. In parallel, ERG enhanced antioxidant defence, as shown by upregulated expression of Sod2, which encodes mitochondrial superoxide dismutase, and reduced expression of the profibrotic Nox4, thereby demonstrating protective actions in the heart. ERG supplementation prevented the HFD-induced increase in the neutrophil-to-lymphocyte ratio, which is a biomarker of the stress response and immune burden. In summary, ERG attenuated HFD-induced maladaptive cardiac remodelling in SHR rats by modulating extracellular matrix composition and reducing fibrosis markers, likely by mitigating the pro-oxidative state. These findings suggest that ERG supplementation could serve as an adjunctive strategy to prevent cardiovascular disease in individuals with hypertension who consume a Western-type diet.\n\nID: 42451667\nTitle: Apigenin Protects Against Cisplatin-Induced Cardiotoxicity: Potential Involvement of CD38-Sirt3 Signaling in Rats.\nAbstract: Cisplatin-induced cardiotoxicity is associated with oxidative stress, inflammation, and apoptosis; however, the role of CD38-Sirt3 signaling remains unclear. This study investigated whether apigenin protects against cisplatin-induced cardiac injury via modulation of CD38-Sirt3 signaling. Male Sprague Dawley rats were assigned to three groups, (1) Control, (2) Cisplatin (5 mg/kg), and (3) Pretreatment with apigenin (50 mg/kg/day) plus cisplatin groups. Then, left ventricular (LV) function, cardiac injury, oxidative stress, inflammation, apoptosis, and CD38-Sirt3 signaling-related proteins were assessed. Cisplatin impaired LV function and induced cardiac injury, oxidative stress, inflammation, and apoptosis in rats. These changes were accompanied by increased cardiac CD38 and decreased cardiac Sirt3 and SOD2 expression. Apigenin significantly improved LV function (%LVEF and %LVFS), reduced cardiac injury (LDH, CK-MB), attenuated oxidative stress, suppressed inflammatory responses (TNF-\u03b1, IL-1\u03b2, p-NF-\u03baB, TLR-4), and inhibited apoptosis (Bax/Bcl-2, cleaved caspase-3). Notably, apigenin improved cardiac SOD2 expression and reversed the alteration of CD38-Sirt3 signaling in cisplatin-treated rats. This study provides evidence that cisplatin-induced cardiotoxicity is associated with alterations in CD38-Sirt3 signaling. Apigenin attenuated LV dysfunction and cardiac injury, reduced oxidative stress, inflammation, and apoptosis, potentially through CD38-Sirt3 signaling. These findings highlight the cardioprotective potential of apigenin against cisplatin-induced cardiotoxicity.\n\nID: 42451165\nTitle: Chlorella Hot Water Extract Restores Collagen Production in Senescent Fibroblasts Through Reversal of miR-193a-5p-Mediated Translational Repression of COL1A1.\nAbstract: Cellular senescence is accompanied by mitochondrial dysfunction and decline in type I collagen production, contributing to age-related tissue deterioration. However, the post-transcriptional mechanisms underlying senescence-associated collagen decline remain poorly understood. Here, we investigated the effects of chlorella hot water extract (CHWE) on mitochondrial function and collagen production in senescent human fibroblasts. CHWE restored mitochondrial membrane potential, ATP production, and redox balance through upregulation of SOD2. Notably, CHWE increased collagen protein levels without altering COL1A1 mRNA, indicating post-transcriptional regulation. miRNA profiling across young, senescent, and CHWE-treated senescent fibroblasts revealed that miR-193a-5p was upregulated during senescence (1.73-fold) and normalized by CHWE treatment. Functional validation confirmed that miR-193a-5p mimic suppressed COL1A1 protein. These findings identify a senescence-miR-193a-5p-COL1A1 axis in which age-dependent miR-193a-5p accumulation represses collagen translation, and CHWE reverses this process. By simultaneously restoring mitochondrial bioenergetic capacity and relieving miRNA-mediated translational repression, CHWE promotes efficient collagen recovery in senescent cells through complementary mechanisms. This study reveals a translational regulatory mechanism of collagen decline during cellular aging and highlights CHWE as a functional food supplement and a potential multi-target agent for age-related tissue deterioration.\n\nID: 42450689\nTitle: Dietary Artemisia ordosica Krasch Supplementation Alters n-3 Polyunsaturated Fatty Acid Deposition and Lipid Metabolism in Cashmere Goat Meat.\nAbstract: Enriching meat with n-3 polyunsaturated fatty acids (n-3 PUFAs) is of considerable nutritional interest because of the well-documented cardioprotective and anti-inflammatory properties of these fatty acids in the human diet. This study investigated the potential effects of dietary Artemisia ordosica Krasch (ARI) supplementation on muscle n-3 PUFA deposition in Albas White Cashmere goats, possibly mediated through the regulation of antioxidant capacity, lipid oxidation, and metabolism. Under the present experimental conditions, ARI supplementation did not significantly affect growth performance, but significantly reduced ruminal C18:0 content (p < 0.05) and increased n-3 PUFA levels (C18:3n3, C22:6n3) in rumen fluid, plasma, liver, and Longissimus dorsi, and the consequent elevation of the muscle PUFA-to-saturated fatty acid ratio (P/S; p < 0.05). Concurrently, ARI supplementation enhanced ruminal and systemic antioxidant capacity, as evidenced by increased glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities, elevated total antioxidant capacity (T-AOC), and upregulated expression of antioxidant-related genes (GSR, GOR, SOD2). Integrated multi-omics analyses revealed that these improvements may be associated with the reduced relative abundance of the core biohydrogenating bacterium s_Butyrivibrio_fibrisolvens and de novo saturated fatty acid synthesis, and potential involvement of the AMPK signaling pathway, with downregulation of FASN; coordinated upregulation of CD36, ACSL3/4, and ELOVL6/7; and upregulation of PPARGC1A, collectively suggesting a promotion of FA oxidation and n-3 PUFA deposition. Collectively, these findings suggest that ARI-promoted n-3 PUFA enrichment in goat meat may be associated with the coordinated modulation of ruminal biohydrogenation, systemic antioxidant capacity, and intermediary lipid metabolism, providing a potential nutritional strategy for developing functional cashmere goat meat.\n\nID: 42449957\nTitle: Molecular Mechanisms of Photobiomodulation in Retinal Diseases: Cytochrome c Oxidase, Mitochondrial Bioenergetics and Cytoprotective Signalling.\nAbstract: Photobiomodulation (PBM) is a non-invasive therapeutic strategy that uses red and near-infrared (NIR) light in the 590-950 nm range to modulate the cellular and molecular pathways involved in retinal homeostasis. At the molecular level, PBM acts primarily through photon absorption by cytochrome c oxidase (CcO, complex IV of the mitochondrial electron transport chain), whose four metal centres-two copper (CuA and CuB) and two heme groups (heme a and heme a3)-absorb light across approximately 600-1000 nm. Photon capture promotes photodissociation of inhibitory nitric oxide (NO) from the binuclear CuB-heme a3 centre, accelerates electron transfer, restores the proton-motive force and increases ATP synthesis. These primary events trigger a coordinated molecular programme that includes (i) transient mitochondrial reactive oxygen species (ROS) bursts that activate the Nrf2/Keap1/ARE axis and upregulate phase II antioxidant enzymes (HO-1, NQO1, GCLC, SOD2, catalase, GPx); (ii) calcium- and cAMP-dependent secondary signalling that converges on PI3K/Akt, MAPK/ERK, AMPK and mTOR pathways; (iii) suppression of NF-\u03baB-driven cytokine production (TNF-\u03b1, IL-1\u03b2, IL-6) and of NLRP3 inflammasome activation; (iv) downregulation of the HIF-1\u03b1/VEGF axis, particularly at 590 nm; (v) anti-apoptotic remodelling of the Bcl-2/Bax ratio with reduced cytochrome c release and caspase-3/9 activation; and (vi) PGC-1\u03b1/TFAM/NRF1-driven mitochondrial biogenesis, alongside restoration of fission/fusion homeostasis (Drp1, Mfn1/2, Opa1) and PINK1/Parkin-mediated mitophagy. Wavelength specificity has a defined molecular basis: 590 nm modulates VEGF signalling and RPE pump activity, 660 nm interacts with the CuB centre and enhances O2 binding at CcO, and 850 nm is absorbed by CuA and supports electron entry into complex IV. A second molecular axis is the bidirectional crosstalk between PBM and the circadian system: mitochondrial respiration, ATP turnover and CcO activity oscillate over the 24 h cycle under the control of the BMAL1/CLOCK and PER/CRY core machinery, the NAD+/SIRT1-SIRT3 axis and REV-ERB\u03b1. Preliminary preclinical and human observations suggest that NIR-induced bioenergetic and functional gains may be coupled to this rhythm, with greater benefit reported when light is delivered in the morning window (\u224808:00-11:00); this time dependence should be regarded as an emerging hypothesis rather than an established clinical principle. The clinical evidence is unevenly developed across indications. It is most robust for non-exudative age-related macular degeneration, where multiwavelength PBM (590/660/850 nm; Valeda Light Delivery System) has shown disease-modifying potential in randomized controlled trials (LIGHTSITE I-III and the LIGHTSITE IIIB extension), with sustained BCVA gains and reduced incidence of geographic atrophy over 24 months and beyond. Evidence for retinitis pigmentosa, central serous chorioretinopathy and, with red-light monotherapy, childhood myopia is at present limited to small or short-term studies and remains preliminary. This narrative review synthesizes the molecular machinery engaged by PBM, integrates clinical findings across retinal diseases and discusses how chronotherapeutic delivery of light, aligned with the molecular clock, may further optimize therapeutic efficacy.\n\nID: 42449940\nTitle: Age-Related Hyperphosphatemia Is Associated with Metabolic and Mitochondrial Alterations During Myogenic Differentiation and in Skeletal Muscle from Old Mice.\nAbstract: Age-related hyperphosphatemia is increasingly recognized as a contributing factor in sarcopenia. This work studies the metabolic effects of elevated phosphate on muscle. C2C12 cells were differentiated in the absence or presence of 10 mM \u03b2-glycerophosphate (BGP), an exogenous phosphate donor. In addition, quadriceps muscles from four experimental groups of male C57BL/6J mice were analyzed: young (5 months) and old (24 months) fed with standard diet; old mice fed with hypophosphatemic diet or supplemented with the phosphate binder Velphoro\u00ae, for the last three months of life. Mice were stratified according to sarcopenia degree based on muscle mass, strength and physical performance. Protein levels were determined by immunoblotting and mRNA expression by RT-qPCR. ATP levels were measured by luminescence and L-lactate production, citrate synthase and cytochrome c oxidase activities by colorimetric assays. Mitochondrial content, membrane potential and reactive oxygen species (ROS) were determined by fluorescence assay. BGP-treated cells showed increased glucose transporter 1 (GLUT1) and decreased NADH Dehydrogenase (CI-NDUFB8) protein expression, elevated hexokinase II (HK2), phosphoglycerate kinase 1 (PGK1) and lactate dehydrogenase A (LDHA) mRNA levels, reduced ATP levels, increased lactate production, and decreased mitochondrial enzyme activities. Moreover, BGP increased ROS, diminished mitochondrial membrane potential, and altered fusion-fission dynamics and mitophagy. In aged quadriceps, oxidative phosphorylation (OXPHOS) subunits and superoxide dismutase 2 (SOD2) expression were reduced. The hypophosphatemic diet improved all parameters, whereas Velphoro\u00ae selectively increased Mitochondrial cytochrome C oxidase subunit 1 (CIV-MTCO1) expression. Several altered mitochondrial markers are associated with sarcopenia degree. Altogether, hyperphosphatemia induces metabolic changes that scale with the sarcopenic degree. Our findings show a relevant association between hyperphosphatemia and mitochondrial dysfunction, and they support the potential benefit of phosphate reduction as a strategy to prevent or mitigate sarcopenia.\n\nID: 42448065\nTitle: Host-microbe signatures of oxidative stress and epithelial apoptosis in bacterial vaginosis during pregnancy.\nAbstract: Bacterial vaginosis (BV) is a common vaginal dysbiosis associated with adverse pregnancy outcomes. However, the extent to which microbial indicators of dysbiosis covary with host oxidative stress and epithelial apoptotic responses during pregnancy remains unclear. In this analytical cross-sectional study, 220 pregnant women were screened at a referral gynecology clinic in Faisalabad, Pakistan; 168 met the eligibility criteria and had concordant modified Amsel and Nugent classifications (56 BV-positive, 112 BV-negative). Cervicovaginal secretions, vaginal swabs, and serum were analyzed for microbial, oxidative stress, and host-response markers. Epithelial-enriched cervicovaginal specimens passing predefined quality criteria (n\u202f=\u202f142) were used for apoptosis-related gene expression and caspase-3/7 activity assays. Targeted microbial quantification focused on Lactobacillus and Acinetobacter spp. Associations between bacterial burden and host markers were evaluated using correlation and regression analyses with the Benjamini-Hochberg false-discovery-rate correction, where applicable. BV-positive participants exhibited a lower Lactobacillus spp. burden and a higher Acinetobacter spp., burden than BV-negative controls. They also showed higher cervicovaginal malondialdehyde and H2O2 concentrations and lower superoxide dismutase and catalase activities (all FDR-adjusted q\u202f<\u202f10-13). Epithelial-enriched specimens from BV-positive participants demonstrated a higher BAX/BCL2 ratio, increased caspase-3/7 activity, increased expression of BAX, CASP9, CASP3, SOD2, and HMOX1, and reduced BCL2 expression. Higher Acinetobacter spp. burden covaried with greater local oxidative stress and increased epithelial apoptosis-associated signaling, although these associations were attenuated after adjustment for BV status. BV in pregnancy was associated with concurrent differences in cervicovaginal microbial indicators, oxidative stress, and epithelial apoptosis-related responses, supporting an integrated host-microbe response at the cervicovaginal interface. These findings provide a foundation for future longitudinal and mechanistic studies investigating host-microbe interactions in pregnancy-associated BV.\n\nID: 42448061\nTitle: Resveratrol exerts anti-aging effects in young but pro-aging effects in middle-aged C. elegans via a gerosuppressive daf-16/dod-6/sod-3 axis.\nAbstract: Aging, a complex process influenced by genetic and environmental factors, is a major determinant of health and disease. The polyphenolic compound resveratrol, known for its antioxidant properties, has been widely studied for its potential anti-aging effects. In this study, we investigated the age-dependent effects of resveratrol in Caenorhabditis elegans (C. elegans). Treatment with resveratrol for four consecutive days in young worms (adulthood day 1-4) significantly enhanced lifespan, healthspan, and reduced reactive oxygen species (ROS) generation. In contrast, the same treatment in middle-aged worms (adulthood day 8-11) unexpectedly impaired these phenotypes. Genetic experiments using mutant strains and RNA interference revealed that the gerosuppressor daf-16 and its downstream antioxidant sod-3 mediate these age-specific effects, as deletion of daf-16 or silencing of sod-3 eliminated the age-dependent opposing responses. Transcriptomic analysis identified distinct gene expression patterns between young and middle-aged worms, with the daf-16-regulated gene dod-6 being up-regulated in young worms but down-regulated in middle-aged worms. Silencing dod-6 abolished the age-dependent opposing effects on lifespan, healthspan, and ROS generation. Further studies confirmed that daf-16 regulates sod-3 through dod-6. Then, the divergent effects of resveratrol were validated in human fibroblast BJ cells: resveratrol reduced \u03b2-galactosidase staining and pro-inflammatory cytokine expression in normal cells but exacerbated these markers in D-galactose-induced senescent cells. Together, these findings demonstrate that resveratrol exerts anti-aging effects in young organisms but promotes aging in middle-aged organisms, likely through differential regulation of the daf-16/dod-6/sod-3 axis. This study highlights the importance of understanding age-related drug susceptibility to develop safer and more effective anti-aging interventions.\n\nID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42384233\nTitle: Genome-wide spectrum of coding DNA variations in Indian patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited therapies, emphasizing the need for deeper understanding of disease pathogenesis. While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.\n\nID: 42375957\nTitle: Application of nano-selenium as a dietary supplement and its effects on antioxidant status and gene expression related to oxidative stress in broiler chickens.\nAbstract: Antioxidants are important factors in reducing stress in poultry birds. Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers.\n\nID: 42375264\nTitle: Proteomic profile of seminal plasma in tropical Saanen bucks under heat stress using 1D-SDS PAGE.\nAbstract: Tropical heat and humidity induce oxidative and thermal stress that threaten male fertility. However, the seminal plasma mechanisms that sustain sperm function under these conditions in goats remain poorly understood. This study aimed to evaluate semen quality and characterize the seminal-plasma proteome of Saanen bucks raised under Indonesia's tropical conditions to identify molecular adaptations associated with fertility resilience. Three healthy bucks (five ejaculates each) were examined using computer-assisted sperm analysis (CASA) for sperm motility, viability, abnormality, membrane and acrosome integrity, and kinematics. Seminal-plasma proteins were separated by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and annotated through Gene Ontology enrichment. While most semen traits and kinematics were comparable among bucks, abnormality and acrosome integrity differed significantly (p < 0.05). A conserved extracellular, vesicle-associated proteome was identified-including BSP1, BSP3, BSP5, ANXA5, ALB, HSPA1A, HSP90AA1, CLU, GPX5, and SOD1-with minor inter-individual variation in LTF, FN1, SPP1, and A2M. Enrichment (FDR < 0.05) highlighted the extracellular region, vesicle, and cytokine-regulatory pathways. This study provides the first proteomic evidence of seminal plasma adaptation to THS in Saanen bucks, revealing a stable core of chaperone, antioxidant, and membrane-coating proteins that safeguard sperm function. These findings establish a novel proteomic basis for heat-resilient fertility and support the development of protein-based sire selection and reproductive management tools in tropical dairy-goat systems.\n\nID: 42375252\nTitle: Impact of cinnamon oil supplementation on broiler performance, intestinal health, gene expression, antioxidant capacity, and hematological parameters.\nAbstract: Cinnamon oil, used as a feed additive in poultry, enhances growth performance, improves antioxidant status, and augments immune response, resulting in superior meat quality and general productive efficiency. This study aimed to assess the effect of cinnamon oil (CO) in broiler diets on growth efficiency, hematological parameters, gene expression, and histological condition. Two hundred sixteen one-day-old broilers were assigned to three treatments in a fully randomized design, with each treatment subdivided into six replicates of 12 chicks. The first treatment is a control group, and the second and third are basic diets with 0.3% and 0.6% CO, respectively. The 0.3% CO group had a higher final body weight, with no significant differences (p \u2265 0.05) in body weight and body weight gain. Birds in this group consumed less FI, leading to a notable improvement in feed conversion rate compared to the control. Additionally, 0.3% CO significantly (p \u2264 0.05) reduced total cholesterol levels without major impacts on most blood parameters, although mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration increased in treated groups. Significant changes were observed in lipase and amylase levels, as well as higher catalase levels and lower malondialdehyde levels. Both 0.3% and 0.6% CO treatments (p \u2264 0.05) increased IGF-1, IL-10, and superoxide dismutase 1 levels, with the 0.6% concentration showing the highest levels. IL-1\u03b2 levels remained low, indicating a specific effect of CO supplementation. Moreover, in the 0.3% CO group, CO supplementation enhanced intestinal absorption by increasing villus height and crypt depth. Adding 0.3% CO to the diet improves feed efficiency, lowers cholesterol, improves blood parameters, lowers inflammation, boosts antioxidant enzymes, and optimally improves intestinal structure, which is beneficial for poultry health and performance.\n\nID: 42374077\nTitle: Clarifying the molecular mechanisms underlying the lethal in vitro cellular effects and mild organismal phenotype of SOD1 loss.\nAbstract: SOD1 is the superoxide dismutase localized principally to the cytoplasm. It is found in all cell types, is extremely abundant, and highly efficient at converting superoxide (O2\u00b7-) to hydrogen peroxide (H2O2). SOD1 and its homologues in the mitochondrial matrix (SOD2) and extracellular environment (SOD3) are the only enzymes that act directly on superoxide. Surprisingly, Sod1-/- knockout mice exhibit only a mild phenotype. In contrast, Sod1-/- cells cannot survive and multiply in vitro. One possibility for the mild in vivo phenotype is that a subtle genome-wide mechanism of developmental compensation attenuates the phenotype. Conversely, many different mechanisms have been proposed to explain the lethality in vitro and the difficulties of rescuing it with antioxidants. Here, we aim to determine the cause of the severe in vitro phenotype of Sod1-/- cells and whether the mild in vivo phenotype of Sod1-/- mice reflects developmental compensation. We provide evidence that the lethality in vitro is directly due to superoxide toxicity and not to more indirect mechanisms. Furthermore, we created a floxed Sod1 gene to compare acute adult-onset organism-wide removal of the protein with constitutive absence in mice and derived cells. We observed no phenotypic differences between acute and chronic loss of SOD1. We discuss how these observations can be reconciled with the evolutionary conservation of high levels of expression of a broadly expressed, high catalytic rate enzyme.\n\nID: 42371060\nTitle: Mechanism-centered target discovery across glomerulonephritis phenotypes: an integrative multi-omics study.\nAbstract: Glomerulonephritis (GN) comprises a heterogeneous group of immune-mediated kidney disorders with substantial biological and clinical diversity. Current treatment still relies largely on broad immunosuppression, underscoring the need for mechanism-informed target discovery across GN phenotypes. We performed a program-guided integrative multi-omics study by combining cis-expression quantitative trait loci and cis-protein quantitative trait loci with GN genome-wide association datasets from UK Biobank, the GWAS Catalog, and FinnGen. Candidate genes were organized into four predefined mechanistic programs: cytokine/TNF signaling, cell-cycle/senescence-repair balance, complement/innate immune activation, and regulated cell-death/redox stress. Six GN-related outcomes were analyzed. Bayesian colocalization, cross-dataset meta-analysis, mouse knockout annotation, drug-repurposing assessment, network pharmacology, and rule-based evidence scoring were used to refine target prioritization. Integrative screening identified 42 transcriptomic and 12 proteomic putative targets, with the strongest enrichment in non-proliferative glomerulonephritis and primary membranoproliferative glomerulonephritis. Bayesian colocalization supported PPP2R1B in non-proliferative glomerulonephritis, SOD1 in IgA nephropathy, and CDK4 in primary membranoproliferative glomerulonephritis. Among 42 transcriptomic gene-outcome pairs taken forward, 11 were supported by cross-dataset meta-analysis. Proteomic meta-analysis supported several cross-dataset signals, including protective associations of ANXA5, GSR, and TNFRSF1B with glomerulonephritis. Across outcomes, complement/innate immunity and cytokine/TNF signaling formed the dominant shared backbone. After separating MHC-region signals for cautious interpretation, 31 non-MHC targets were retained for primary prioritization, with PPP2R1B, CDK4, and SOD1 comprising the top tier. This mechanism-centered integrative multi-omics study delineates shared and phenotype-enriched biological programs across the GN spectrum and identifies a prioritized set of candidate targets for future validation and therapeutic development.\n\nID: 42364425\nTitle: Effects of SGLT2 inhibitor dapagliflozin on the heart of rats with long-standing Type 1 diabetes mellitus: Protein profile.\nAbstract: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have beneficial outcomes on the renal and cardiovascular system in diabetes mellitus (DM) patients. As most clinical trials were performed in Type 2 DM, the effects of SGLT2 inhibition in Type 1 DM are not completely clarified. To evaluate the effects of long-standing SGLT2 inhibitor dapagliflozin on the protein profile in rats with a Type 1 DM model. Male Wistar rats were divided into Control (C), DM, and DM treated with dapagliflozin (DM+DAPA) for 30 weeks. DM was induced by a single injection of streptozotocin (40\u202fmg/kg); dapagliflozin was added to chow (5\u202fmg/kg/day). Label-free mass spectrometry was used to assess left ventricular proteome. The bioinformatic tools used were STRING, Cytoscape, Cluster Marker, and ClueGO. ANOVA and Tukey or Kruskal-Wallis and Dunn. Dapagliflozin attenuated body weight loss (C 574\u202f\u00b1\u202f43; DM 339\u202f\u00b1\u202f31*; DM+DAPA 413\u202f\u00b1\u202f30*# g; p\u202f<\u202f0.05 * vs C; # vs DM) and reduced glycemia [C 108 (101-111); DM 554 (529-562)*; DM\u202f+\u202fDAPA 343 (237-416)*# mg/dL; p\u202f<\u202f0.05 * vs C; # vs DM]. Most proteins identified in the networks downregulated in DM vs C were upregulated in DM\u202f+\u202fDAPA vs DM. Proteins related to energy metabolism (CKm, Ak1, Atp5pf, Mdh1, Idh2), excitation-contraction coupling (Actc1, Casq2, Serca1, Serca2a), and oxidative stress (Sod1, Sod2) were upregulated in DM\u202f+\u202fDAPA. KEGG pathways enriched in DM vs Control included gap junction, necroptosis, and fatty acid degradation (upregulated), and Alzheimer's disease, cardiac contraction, and glycolysis/gluconeogenesis (downregulated). In DM\u202f+\u202fDAPA vs DM, upregulated pathways included Parkinson's disease, cardiac contraction, citrate cycle, necroptosis, and cyclic guanosine monophosphate-dependent protein kinase (PKG) signaling pathway; downregulated proteins were linked to ketone body metabolism. Dapagliflozin modulates cardiac protein abundance by attenuating DM-induced changes in Type 1 DM rats.\n\nID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\n\nID: 42352067\nTitle: Urate as a CO3\u2022- Scavenger and Regulator of SOD-1 and OGG1 Enzymes: Insights from DFT, Molecular Docking, and Molecular Dynamics.\nAbstract: The potency of urate, an abundant human plasma antioxidant, in preventing oxidative damage caused by the carbonate radical anion CO3\u2022-, was studied using quantum chemical calculations. The influence of microhydration of CO3\u2022-/CO32- and urate-/urate\u2022 couples on the thermodynamic and kinetics of the one-electron oxidation process was investigated. Depending on the degree of microhydration, the estimated rate constant for one-electron transfer is in the range of 2.0-7.3 \u00d7 109 M-1 s-1, in good agreement with the experimental value of 1.3 \u00d7 109 M-1 s-1. Modeling using vertical detachment energy and electron affinity, the driving forces of single electron transfer revealed urate(H2O)6- and CO3(H2O)9\u2022- clusters as the most likely existing species in water. Molecular docking revealed a favorable interaction of urate with the catalytic pocket of SOD1. Urate binds more strongly to the anionic active center of SOD1 than the reference inhibitor LSC-1, indicating its potency to prevent HCO3--supported CO3\u2022- formation. In contrast, the known OGG1 inhibitor TH13264 shows substantially stronger binding than urate, indicating urate's weaker affinity toward the DNA repair enzyme catalytic pocket. The molecular dynamics data indicate that urate binding does not destabilize either SOD1 or OGG1. In light of increasing evidence that the major source of oxidative stress could be CO3\u2022-, rather than the commonly assumed hydroxyl radical HO\u2022, the obtained results indicate the inherent ability of plasma to combat oxidative stress induced by this selective, milder oxidant. Such an ability with respect to the non-selective, highly reactive HO\u2022 does not exist in vivo.\n\nID: 42351978\nTitle: Loss of NRF2 During Aging Contributes to Myocardial Functional Decline.\nAbstract: Aging is a significant risk factor for cardiovascular diseases. The prevalence of heart failure increases with age, making it a leading cause of morbidity and mortality. We investigated age-associated changes in expression of Nuclear Factor (Erythroid-derived 2)-Like 2 (NFE2L2 or NRF2) in the myocardium of humans, rhesus monkeys, Fischer rats, and C57BL/6 mice. NRF2 is a transcription factor that orchestrates the expression of genes involved in antioxidant and detoxification responses. Analyses of RNA-seq data from the Genotype-Tissue Expression (GTEx) project, which contains left ventricular samples from 294 male donors, revealed a trend of age-associated declines in NRF2 transcripts and several of its downstream genes (SOD1, SOD2, CAT, GCLM, and AKR1B). Age-dependent decreases in NRF2 protein expression were observed in the myocardium of Rhesus monkeys and Fischer rats. To determine whether NRF2 loss contributes to myocardial aging, we evaluated cardiac function of NRF2 knockout mice (KO) at 19 and 24 months of age. At 19 months, the NRF2 KO mice exhibited diastolic dysfunction, characterized by an increased end-diastolic volume (EDV) and end-systolic volume (ESV), accompanied by a reduced ejection fraction (EF) and fractional shortening (FS), indicative of early onset of heart failure. The NRF2 KO mice displayed premature aging phenotypes and had reduced lifespans. Our findings support the trend of NRF2 signaling decline with age, and that loss of NRF2 accelerates the maladaptive cardiac remodeling and functional deterioration associated with aging.\n\nID: 42343520\nTitle: [Effect of electroacupuncture at \"Zusanli\" (ST36) on TREM2-mediated microglial activation in amyotrophic lateral sclerosis mice].\nAbstract: To observe the effect of electroacupuncture (EA) at \"Zusanli\" (ST36) on amyotrophic lateral sclerosis (ALS) in mouse models based on myeloid cell trigger receptor 2 (TREM2)-mediated microglial activation. Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1\u03b2, \u03b3 interferon (IFN-\u03b3), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1\u03b2, IFN-\u03b3, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1\u03b2 and IFN-\u03b3 decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1\u03b2,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05). Electroacupuncture at \"Zusanli\" (ST36) exhibits a certain improvements in motor function of SOD1-G93A transgenic mice.

Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration.\n\nID: 42335888\nTitle: An emergent disease-associated motor neuron state precedes cell death in ALS.\nAbstract: To define molecular determinants of motor neuron degeneration in amyotrophic lateral sclerosis (ALS), we generated longitudinal single-nucleus transcriptomes and chromatin accessibility profiles of spinal motor neurons together with spatial transcriptomics from the SOD1-G93A mouse model. Vulnerable alpha motor neurons showed thousands of molecular changes, marking a transition into a distinct cell state we named \"disease-associated motor neurons\" (DMs). We identified transcription factor networks that govern how healthy cells transition into DMs and those associated with motor neuron subtype-selective vulnerability. Upregulation of DM-associated transcription factors in human motor neurons induced key features of DMs, demonstrating an active regulatory component. Human ALS spinal cord single-nucleus RNA sequencing data demonstrated conservation of the DM signature in alpha motor neurons, and human orthologs of regions differentially accessible in SOD1-G93A mouse motor neurons were enriched for ALS genetic risk variants. Together, these findings establish a conserved, genetically linked motor neuron signature in ALS.\n\nID: 42334525\nTitle: Synthesis and multilevel evaluation of benzimidazole-based anticancer compounds: DNA/serum albumin interaction, and in-depth theoretical insights.\nAbstract: Within the scope of this investigation, two novel compounds (3a and 3b) were designed and synthesized in two steps. Compounds 3a and 3b were tested utilizing the MTT study to evaluate their in vitro cytotoxic activity against healthy human embryonic kidney, lung cancer, breast cancer, and human liver cancer cell lines. It was determined that compound 3b exhibited high levels of cytotoxic activity against both liver and breast cancer cell lines, with IC50 values of 10.83 and 11.55 \u00b5M, respectively. Also, to elucidate the anticancer mechanism of compounds, pro-apoptotic BAX and BiD, anti-apoptotic BCL2 and BCL-xl, oxidant enzymes PRDX1 and SOD1 levels were examined by RT-qPCR. Moreover, cellular oxidative stress levels were spectrophotometrically measured, and cellular senescence was evaluated via the senescence-associated \u03b2-galactosidase test. DFT calculations and RDG, ELF, and LOL analyses were performed to demonstrate the reactivity of these compounds. Compounds significantly down-regulated anti-apoptotic genes, whereas mRNA levels of pro-apoptotic genes were up-regulated in MCF-7 cells. Moreover, oxidative stress status was significantly increased depending on the compound treatment. Consistently, PRDX1 and SOD1 levels were also significantly up-regulated. Furthermore, cellular senescence was significantly induced by the compounds. Fluorescence spectroscopy demonstrated strong binding of both compounds with CT-DNA, characterized by static quenching mechanism and binding constants of 6.02\u2009\u00d7\u2009106M-\u20091(for 3a) and 8.69\u2009\u00d7\u2009106M-\u20091(for 3b), suggesting an intercalative binding mode. In contrast, moderate affinity toward BSA indicated suitable transport characteristics with reduced nonspecific protein binding. Molecular docking studies supported the experimental findings. These combined results verify the potential of the synthesized derivatives as promising candidates for further investigation as biologically active anticancer agents.\n\nID: 42327579\nTitle: Assessing the Association Between Genetic Variants in ACE, SOD1, and PER3 and their Role in Breast Cancer Risk among Jordanian Women.\nAbstract: Genetic and environmental factors regulate many physiological processes in the human body, and alterations in these processes may contribute to the development of various diseases, including breast cancer (BC), which is considered the most prevalent cancer among women and a leading cause of cancer-related mortality in the Jordanian population. Genes such as ACE, SOD1 and PER3 play important roles in regulating essential biological functions. These genes are involved in key physiological pathways, including blood pressure regulation, oxidative stress response and circadian rhythm maintenance, and genetic variants within them may influence susceptibility to cancer. Therefore, this study investigates the association between polymorphisms in the ACE, SOD1 and PER3 genes and the risk of breast cancer, with the aim of evaluating how these genetic variations relate to breast cancer susceptibility and clinical outcomes in Jordanian women. Blood samples of 300 women diagnosed with breast cancer, along with 300 healthy participants, were collected, and DNA was extracted from them. Genetic variants in the ACE (rs1799752), SOD1 (rs36232792) and PER3 (rs57875989) genes are examined through employing direct PCR to amplify the target regions. The ACE (rs1799752) variant was observed to be associated with breast cancer susceptibility, with the I/I genotype increasing risk of breast cancer (OR = 5.138, 95% CI = 1.38-19.03, p = 0.014). No associations were observed for SOD1 (rs36232792) and PER3 (rs57875989) variants. The rs1799752 polymorphism is suggested to have the potential of serving as a biomarker for breast cancer susceptibility in Jordanian women, as it is associated with elevating the risk.\n\nID: 42320547\nTitle: Proteomic analysis reveals early pathological defects in corticospinal motor neurons of a spastin model of hereditary spastic paraplegia, which are improved by NU-9 treatment.\nAbstract: Upper motor neuron (UMN) degeneration is a characteristic feature of hereditary spastic paraplegia (HSP), a genetically heterogeneous heritable neurodegenerative disorder resulting from mutations in over ninety genes. The mutations in the SPAST gene, which encodes the microtubule-severing protein spastin, are responsible for about 40% of all HSP cases. To date, the cellular and molecular mechanisms linking mutant spastin protein to UMN vulnerability in HSP patients remain unknown and there are no disease modifying therapies. To address this knowledge gap, we isolated pure populations of corticospinal motor neurons (CSMN; a.k.a. UMN in mice) from SPASTC448Y-UeGFP reporter mice at two pre-symptomatic time points and performed bottom-up proteomic analyses to reveal changes in their proteome that informs the underlying causes of their initial vulnerability. We find dynamic changes in their proteome and that limitations with cytoarchitectural integrity and stability of key organelles contribute to their neuronal vulnerability. Since the compound NU-9 was shown to improve similar cellular problems in CSMN that are diseased due to misfolded SOD1 toxicity and TDP-43 pathology, we further investigated its effect on the well-established pathological features of HSP that are recapitulated in the SPASTC448Y mice. We find that NU-9 treatment (100\u00a0mg/kg, for 100\u00a0days) significantly prevented degeneration of corticospinal axons, restored the integrity of mitochondria and endoplasmic reticulum, and reduced the presence of electron-dense accumulations in the CSMN of SPASTC448Y mice.\n\nID: 42315786\nTitle: Scalable diclofenac lauryl ester prodrug nanoparticles: a promising strategy for reducing inflammation associated with intervertebral disc degeneration.\nAbstract: As the most frequent clinical problem, intervertebral disc degeneration (IVDD) and associated inflammatory pain are still a big challenge, thus there is a need for improved and more lasting therapeutic approaches. In this study, a lipidic prodrug of diclofenac, Diclofenac Lauryl Ester (L-DCF), was synthesized and formulated into nanoparticles (Nanofenac-L) using the ethanol injection method followed by microfluidization. The encapsulation efficiency of Nanofenac-L was >\u200997% with sustained drug release, releasing around 65% of the diclofenac in 48\u00a0h. The therapeutic potential of Nanofenac-L was evaluated in rat intervertebral disc-derived nucleus pulposus cells.\u00a0Nanofenac-L was found to be more effective than free Diclofenac Sodium (DCF-Na) in terms of anti-inflammatory activity, which was confirmed with significant suppression of COX-2 and Substance P. Furthermore, Nanofenac-L increased the expression of antioxidant genes in cells, such as SOD1, GPX1 and PRDX1. Preventive treatment was found to have shown therapeutic value whereas the curative treatment yielded a significant therapeutic effect indicating the possibility of Nanofenac-L to alleviate inflammation as well as to slow down disease progression. Altogether, these results suggest that Nanofenac-L could represent a promising long-lasting anti-inflammatory, pain relieving and antioxidant nanotherapeutic. Comprehensive preclinical and clinical evaluation is essential to translate these findings into viable therapies.\n\nID: 42313275\nTitle: Immune response in honey bees (Apis mellifera) following humic substance feeding.\nAbstract: Humic substances (HS) are increasingly investigated as natural additives to support health in humans and animals, yet their effects on honey bees remain insufficiently characterised. This study evaluated the impact of a commercial HS-based product on immunity and oxidative status of Apis mellifera. Newly emerged worker bees were kept under laboratory conditions and fed sugar syrup supplemented with 0.5% HS for seven days, while the control group received unsupplemented syrup. Effects of HS were evaluated by analysing the expression of selected immune-related genes, quantifying antimicrobial peptides (AMPs), measuring the activity of antioxidant enzymes, evaluating lipid peroxidation, and characterising hemocyte populations. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. Similarly, catalase enzymatic activity was significantly decreased in the HS group. No significant changes were detected in gene expression for other AMPs and relative abundance of AMPs, or other antioxidant parameters. HS supplementation significantly increased the proportion of medium granular hemocytes (p\u2009<\u20090.05) at the expense of high granular cells (p\u2009<\u20090.01). In conclusion, the 7-day administration of HS at 0.5% did not adversely affect bee health and modulated selected immune parameters. The biological significance of these immunomodulatory effects requires confirmation through challenge studies and field trials under natural conditions.\n\nID: 42299014\nTitle: Pathogenic Proteins Driving ALS Pathogenesis: Molecular Mechanisms and Translational Therapeutic Perspectives.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive degeneration of motor neurons, with protein aggregation as a central pathological hallmark. Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.\n\nID: 42288788\nTitle: Overexpression of the EfMYB124 gene from Erianthus fulvus enhances tolerance to low temperature and drought in Arabidopsis thaliana.\nAbstract: Environmental factors such as low temperature and water stress often hinder the normal growth of sugarcane (Saccharum spp.), which threatens the supply of raw materials for sugar and biomass provided by sugarcane, resulting in severe economic development losses. Improving the stress resistance of sugarcane has always been one of the important directions in sugarcane breeding. Erianthus fulvus, a wild relative of sugarcane, exhibits remarkable stress tolerance. Therefore, fully exploring the excellent stress-tolerance genes in E. fulvus can provide important candidate genes for improving the stress resistance of sugarcane in future molecular breeding programs. The evolutionary characteristics of EfMYB124, a gene induced by low temperature and drought, were analysed. Moreover, the gene was successfully transferred into Arabidopsis thaliana, and the degree of damage, physiological responses, and stress-induced gene expression of the transgenic plants under stress were investigated. EfMYB124 is most closely related to At1R-MYB in group A1, and the members of this group have the potential to function in response to adverse stress. Numerous syntenic genes of EfMYB124 were identified in the sugarcane genome. Under drought and low-temperature treatments, the EfMYB124-transgenic plants exhibited relatively mild external damage. Moreover, the activities or contents of three antioxidant enzymes (CAT, POD, and SOD) and Pro in these plants increased rapidly, while the production of MDA decreased. Further analysis revealed that EfMYB124 could specifically regulate the expression of cold stress-related genes (CBF1, CBF3, COR15a, and COR4) and drought stress-related genes (RD29A, P5CS1, SOD1, and CAT2). Additionally, EfMYB124 represses the basal expression levels of key ABA signaling-related genes, including NCED3, ABI5, ABF2, and RD29B. In summary, this study has initially confirmed that EfMYB124 plays a positive role in regulating plants' resistance to drought and low temperatures. These key findings lay a solid foundation for us to further analyze the function of EfMYB and study its upstream and downstream interaction relationships. Meanwhile, they provide the necessary scientific reference for the future application of this gene in the genetic improvement of stress tolerance trait breeding in sugarcane.\n\nID: 42278291\nTitle: Targeting Autoimmune Myocarditis with Lemon Balm Extract: In Vivo Molecular Approach.\nAbstract: Due to the complex pathophysiology and serious outcomes of autoimmune myocarditis, we sought to determine whether ethanolic lemon balm extract (LBE) could attenuate disease progression and development of dilative cardiomyopathy (DCM). EAM was induced in Dark Agouti rats by immunization with porcine myosin. Fifty animals were allocated to five groups: healthy controls, untreated EAM, and EAM treated with LBE (50, 100, or 200 mg/kg) for six weeks. Hemodynamic parameters were monitored, and echocardiography assessed cardiac structure and function. Inflammatory, oxidative, fibrotic, and apoptotic markers were analyzed. Immunological profiling revealed that LBE significantly decreased proinflammatory cytokines (IL-1, IL-6, TNF-\u03b1, IL-4, IL-17) while restoring anti-inflammatory IL-10 levels (p < 0.05). Antioxidant activity was confirmed by reduced levels of O2-, H2O2, and TBARS, accompanied by significant increases in SOD, CAT, and GSH activity (p < 0.05), and upregulation of SOD1 and SOD2 gene expression. Additionally, LBE (200 mg/kg) markedly reversed fibrotic remodeling through suppression of TGF-\u03b2 expression and collagen deposition, as shown by Sirius Red staining, and mitigated apoptosis by modulating Bax/Bcl-2 balance and reducing TUNEL-positive cells. Collectively, these findings suggest that LBE exerts strong cardioprotective effects in EAM by regulating inflammatory, oxidative, fibrotic, and apoptotic pathways, thereby preventing myocarditis progression toward DCM.\n\nID: 42249210\nTitle: Dietary patterns characterized by high fiber intake in vegan and omnivorous individuals are associated with distinct salivary proteomic signatures linked to oral homeostasis.\nAbstract: We compared the salivary proteome and metaproteome of individuals with real-world dietary patterns differing in fiber intake (i.e., high- versus low-fiber intake) to examine whether their diet was associated with distinct molecular signatures in saliva. Sixteen participants from a cross-sectional study were classified into high-fiber (n\u2009=\u20098) and low-fiber (n\u2009=\u20098) intake groups based on dietary assessment. Although these groups corresponded to vegan and omnivorous patterns, respectively, classification was based on fiber intake. Groups were matched for age, sex, socioeconomic status, while major dietary differences inherent to vegan and omnivorous patterns were explicitly considered in the interpretation. Stimulated whole saliva was collected under standardized fasting conditions. Human proteomic and microbial metaproteomic analyses were performed using bottom-up DIA-PASEF. Differentially abundant proteins, enriched pathways, and metaproteomic profiles were identified using bioinformatic analyses. From 3,332 identified proteins, 1,566 were quantifiable, and 66 were differentially abundant between groups (FDR [False Discovery Rate]\u2009<\u20090.05). Multivariate analyses revealed separation according to dietary patterns differing in fiber intake: high-fiber exhibited enrichment of homeostasis, lipid metabolism, and cytoprotective pathways, with increased abundance of PRP-1/2, CA6, APOA1, and HYOU1. Low-fiber showed enrichment of immune and oxidative stress pathways, with higher SOD1, GPX1, ANXA2, ANXA8, and S100A8. Metaproteomics analysis revealed no major taxonomic differences but greater interindividual variability in the low-fiber intake group. Dietary patterns characterized by different dietary fiber intake appear associated with distinct salivary proteomic signatures. Although the contribution of other co-occurring dietary factors cannot be excluded, these findings, based on a small, highly selected cohort, suggest that fiber-rich dietary patterns may support oral homeostasis through host-driven molecular pathways rather than major shifts in microbial composition. Our findings strengthen the rationale for considering dietary patterns with high-fiber intake not only as a systemic health determinant but also as a modulator of salivary molecular functions relevant to oral disease prevention and personalized care.\n\nID: 42239283\nTitle: Chronic diazepam reveals excessive homeostatic gain in SOD1G93A mouse spinal motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\n\nID: 42224592\nTitle: miR-146a is a pleiotropic regulator of motor neuron degeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons. Here, we have profiled motor neuron microRNAs (miRNAs) during motor neuron degeneration in vivo to gain a better understanding of ALS pathophysiology. We demonstrate that one miRNA, miR-146a, is downregulated in diseased motor neurons despite upregulation in bulk tissue. Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit. A corresponding reduction in spinal cord gliosis but not motor neuron loss was observed. Finally, we observed that a proportion of miR-146a knockout animals develop spontaneous paralysis, motor neuron loss and chronic neuroinflammation with advanced age. Together these findings demonstrate that a single miRNA influences multiple aspects of motor neuron disease and highlights the complex role for neuroinflammation in ALS pathogenesis.\n\nID: 42213237\nTitle: Reevaluating the role of beta2-microglobulin: new insights on selective vulnerability in ALS pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterized by the selective loss of motor neurons (MNs). Why these neurons are particularly vulnerable in ALS remains\u00a0unclear, as does why certain MN groups\u00a0remain resistant\u00a0throughout the disease course. We investigated the role\u00a0of the human leukocyte antigens (HLAs) and beta2-microglobulin (\u03b22m) in MN susceptibility to ALS, given their reported involvement in\u00a0both prolonging and shortening disease\u00a0progression. Loss of HLAs in ALS has also been\u00a0shown to increase MNs vulnerability to toxicity exerted by activated astrocytes. RNA\u00a0sequencing of control tissues\u00a0demonstrated that disease-resistant oculomotor neurons (OMNs) and Onuf's MNs exhibited \u03b22m and HLA mRNA levels comparable\u00a0to those of\u00a0vulnerable spinal MNs, suggesting that\u00a0baseline differences in these transcripts do not explain the differential vulnerabilities\u00a0of\u00a0these MN groups. However, HLA protein levels showed an inverse correlation with spinal MN size, with the large MNs, those lost early in ALS, displaying the\u00a0lowest HLA expression. HLA protein levels were also reduced in spinal MNs from\u00a0end-stage ALS patient\u00a0tissues, while remaining relatively\u00a0unchanged in OMNs. In contrast, spinal MNs uniquely exhibited significant upregulation of \u03b22m and HLA-C transcripts during disease, likely reflecting a protective compensatory response. Together,\u00a0these findings suggest that \u03b22m and HLAs may contribute to spinal MN\u00a0vulnerability in ALS. To assess their functional role, \u03b22m\u00a0knockout mice were crossbred\u00a0with SOD1G93A ALS mice. Loss of \u03b22m\u00a0did not alter life span\u00a0of the ALS mice, but led to\u00a0partial preservation of lumbrical muscle\u00a0innervation that\u00a0was insufficient to maintain motor function. Analysis of GFAP immunoreactivity revealed marked neuroinflammation activation\u00a0in the\u00a0spinal cords of \u03b22m knockout mice. As these mice retain normal MN numbers\u00a0and life-span, this indicates that loss of functional MHC-I, even in the presence of\u00a0astrocyte activation, is insufficient to cause MN disease. Furthermore, \u03b22m knockout significantly increased GFAP activation in SOD1G93A mice, but did not further exacerbate disease progression, suggesting\u00a0that loss of functional MHC-I does not necessarily render MNs more vulnerable to\u00a0astrocyte toxicity. Overall,\u00a0these findings indicate that \u03b22m and HLAs are dynamically regulated in ALS, and may influence MN vulnerability, but they are not major disease\u00a0modifiers in ALS.\n\nID: 42212756\nTitle: 5-Hydroxytryptamine Distribution Alteration in Both Neuron and Synapse of Tg(SOD1*G93A)1gur Mice: A Potential Intervention Candidate Strategy for Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease; the precise pathogenesis of sporadic ALS (sALS) has not yet been elucidated up to now. Previous studies revealed that the abnormal alterations of some non-motor neurons (non-MN) were a potential pathogenesis of sALS. Therefore, this study aims to search the potential evidences of non-MN in the pathogenesis of ALS via exploring potential relationships between 5-hydroxytryptamine (5-HT) neurons and the development of ALS. We employed fluorescent immunohistochemistry to investigate the altered distribution patterns of 5-HT and tryptophan hydroxylase 2 in the spinal cord and brainstem of Tg(SOD1*G93A)1Gur (TG) and wild-type (WT) mice. Additionally, we used western blot to analyze the expression levels of 5-hydroxytryptamine receptor 1A (5-HTR1A) and 5-HTR2A. Our findings revealed that 5-HT synapses were primarily distributed in the funiculus lateralis, anterior horn, posterior horn, central lateral column, and the area around the central canal of cervical, thoracic, and lumbar segments, and raphe nucleus as well as lateral paragigantocellular nucleus, and gradually reduced following age increase in WT mice. However, 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem gradually increased following the progression of disease and presented a significantly negative correlation between the increased distribution of 5-HT synapses and neurons and the reduction of neural cell number (positively correlated with the increase in neural cell death) at the onset and/or progression stage of TG mice. 5-HTR1A significantly increased, while 5-HTR2A significantly decreased at the onset stage of TG mice. Our study speculated that the distribution changes of 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem play a potential protective role in the pathogenesis of sALS through a compensatory 5-HT increase.\n\nID: 42199117\nTitle: An integrated single-nucleus ribonucleic acid sequencing and spatial transcriptomic atlas reveals stage-specific neuronal and glial trajectories in a mouse model of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a progressive multifocal neurodegenerative condition involving motor neurons and other cell types. To analyze spatiotemporal cellular dynamics in amyotrophic lateral sclerosis, we performed single-nucleus ribonucleic acid sequencing and spatial transcriptomics analysis of cervical spinal cords from wild-type control mice and SOD1-G93A transgenic mice in the pre-symptomatic (d50), early symptomatic (d90), and late-stage (d130) phases of disease. Single-nucleus ribonucleic acid sequencing identified 17 cell clusters and showed that progressive neuronal loss occurred over time, paralleled by glial expansion. Spatial transcriptomics mapped these clusters anatomically onto oligodendrocytes in white matter, neurons in horns, and diffuse astrocytes/microglia. Subcluster analysis demonstrated neuronal heterogeneity, with early mitochondrial stress in ventral motor neurons evolving into synaptic dysfunction, transient maturation peaks in interneurons, and amplified age-related decline in amyotrophic lateral sclerosis. Astrocyte and oligodendrocyte subclusters, which were originally misclustered due to spot-level contamination, were reinterpreted to highlight A1-reactive states and progenitor expansions, validated by immunohistochemistry detection of serum/glucocorticoid regulated kinase 1. Temporal profiles tracked the transition from compensatory to inflammatory gliosis, while gene signatures were linked to human amyotrophic lateral sclerosis cohorts, including complement activation and mitochondrial dysfunction. This study provides a high-resolution spatiotemporal cellular map of amyotrophic lateral sclerosis pathogenesis through the integration of single-nucleus and spatial transcriptomics, uncovering early mitochondrial impairment in neurons, delineating the trajectory of neurotoxic glial states, and identifying compensatory progenitor responses, to highlight the highly intricate interaction between glial reactivity and neuronal susceptibility that drives the pathogenesis of ALS.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

However, the extent to which microbial indicators of dysbiosis covary with host oxidative stress and epithelial apoptotic responses during pregnancy remains unclear. In this analytical cross-sectional study, 220 pregnant women were screened at a referral gynecology clinic in Faisalabad, Pakistan; 168 met the eligibility criteria and had concordant modified Amsel and Nugent classifications (56 BV-positive, 112 BV-negative). Cervicovaginal secretions, vaginal swabs, and serum were analyzed for microbial, oxidative stress, and host-response markers. Epithelial-enriched cervicovaginal specimens passing predefined quality criteria (n\u202f=\u202f142) were used for apoptosis-related gene expression and caspase-3/7 activity assays. Targeted microbial quantification focused on Lactobacillus and Acinetobacter spp. Associations between bacterial burden and host markers were evaluated using correlation and regression analyses with the Benjamini-Hochberg false-discovery-rate correction, where applicable. BV-positive participants exhibited a lower Lactobacillus spp. burden and a higher Acinetobacter spp., burden than BV-negative controls. They also showed higher cervicovaginal malondialdehyde and H2O2 concentrations and lower superoxide dismutase and catalase activities (all FDR-adjusted q\u202f<\u202f10-13). Epithelial-enriched specimens from BV-positive participants demonstrated a higher BAX/BCL2 ratio, increased caspase-3/7 activity, increased expression of BAX, CASP9, CASP3, SOD2, and HMOX1, and reduced BCL2 expression. Higher Acinetobacter spp. burden covaried with greater local oxidative stress and increased epithelial apoptosis-associated signaling, although these associations were attenuated after adjustment for BV status. BV in pregnancy was associated with concurrent differences in cervicovaginal microbial indicators, oxidative stress, and epithelial apoptosis-related responses, supporting an integrated host-microbe response at the cervicovaginal interface. These findings provide a foundation for future longitudinal and mechanistic studies investigating host-microbe interactions in pregnancy-associated BV.\n  --- END ACTUAL ABSTRACT FOR 42448065 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy.\" (Source: 42406382)\n- \"These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS.\" (Source: 42458007)\n- \"61% of respondents reported that Health Canada approval of tofersen directly influenced their practice.\" (Source: 42410102)\n- \"Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models.\" (Source: 42489267)\n- \"Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species.\" (Source: 42398690)\n- \"This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs.\" (Source: 42402967)\n- \"Our findings show a relevant association between hyperphosphatemia and mitochondrial dysfunction, and they support the potential benefit of phosphate reduction as a strategy to prevent or mitigate sarcopenia.\" (Source: 42449940)\n- \"The expression levels of CAT, copper (Cu)/zinc (Zn)-superoxide dismutase (Cu/Zn-SOD), heat shock protein 70 (HSP70), heat shock protein 90 (HSP90), and metallothionein (MT2) genes were significantly upregulated.\" (Source: 42437042)\n- \"Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001).\" (Source: 42375957)\n\n\nINSTRUCTION: Study the actual abstracts provided.

This evolution is driven by the regulatory approval and clinical integration of antisense oligonucleotides and siRNA-conjugates. Simultaneously, research has expanded to include systemic factors\u2014such as platelet-derived factors and autophagy-regulating small molecules\u2014and a high-resolution understanding of the \"disease-associated motor neuron\" (DM) state, which provides a conserved molecular roadmap for future therapeutic targeting.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe field of SOD1-ALS has undergone rapid transformation, defined by the clinical maturity of targeted gene-lowering therapies. The integration of such interventions into standard care has necessitated nationwide shifts in genetic testing protocols, as evidenced by the observation that 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Mechanistic studies now link toxic protein aggregation with converging cellular stressors, including mitochondrial failure and oxidative dysregulation. Emerging therapies target these specific pathological vulnerabilities; for instance, hydrogen gas scavenging and autophagic modulation demonstrate efficacy in preclinical SOD1-G93A models. The complexity of these interactions is reinforced by the identification of discrete \"disease-associated motor neuron\" states that precede physical degeneration, providing a temporal window for early therapeutic intervention. Despite these strides, research continues to navigate the clinical challenges posed by phenotypic dissociation and the limitations of targeting single proteins in a multifaceted neurodegenerative cascade.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Pathology-Selective Efficacy:** Therapeutic interventions like PF4 demonstrate robust rescue in SOD1-driven models but remain ineffective in TDP-43 or C9orf72 models.\n*   **Systemic Autophagy:** The discovery of a peripheral platelet-autophagy-neuron axis allows systemic factors to directly influence central proteostatic machinery.\n*   **Temporal Precision:** The identification of \"disease-associated motor neurons\" (DMs) suggests that motor neuron vulnerability is a staged molecular trajectory, not an abrupt event.\n*   **Hydrogen Therapy:** Mutant SOD1 acts as both a catalyst for hydroxyl radical generation and a potential hydrogenation catalyst, allowing for novel hydrogen-based scavenging therapies.\n*   **Diagnostic Evolution:** The shift from familial-only testing to universal screening for sporadic ALS reflects a clinical standard redefined by the availability of disease-modifying therapies.\n*   **Phenotypic Dissociation:** There is growing clinical recognition of biomarker-clinical dissociation, where functional decline may not always mirror molecular marker trends.\n*   **Targeting the Microenvironment:** Modulating the TREM2-mediated inflammatory state of microglia represents a viable pathway for slowing disease progression.\n*   **Compensatory Homeostasis:** SOD1-G93A spinal motoneurons display \"overactive\" homeostatic control, suggesting that dysfunction involves failed feedback regulation rather than simple excitability shifts.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies."

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues."

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total).

Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported.

However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097."

Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen).

This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers."

Evidence confirms that while therapeutic SOD1-lowering strategies like tofersen and siRNA-conjugates show promise, outcomes can be heterogenous, and targeting non-SOD1 pathways remains a critical frontier.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis of recent literature indicates that SOD1-targeting therapies have achieved reliable reduction of protein levels in human central nervous system tissues. However, the diagnostic and prognostic landscape is increasingly reliant on multimodal biomarkers, including neurofilament light chain (NfL) and neuromuscular ultrasound, to manage the clinical complexity of SOD1-ALS and potential therapeutic failures in non-SOD1 patient cohorts.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic landscape for SOD1-ALS has undergone rapid evolution, marked by the clinical validation of antisense oligonucleotides (ASOs) and siRNA-based strategies. The distribution of tofersen in human central nervous system tissues has been confirmed, showing that \"In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model.\" While these molecular interventions show efficacy in reducing protein levels\u2014confirmed as \"The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study\"\u2014the clinical response can be paradoxical. Specifically, the risk of misapplication in non-SOD1 populations is documented, as evidenced by a case where \"In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease.\" Beyond traditional genetics, research now encompasses systemic modulators, where \"Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Macrophagic Inclusions:** Clinical monitoring of ASO therapy reveals frequent, persistent inclusions in cerebrospinal fluid, though their functional impact on therapeutic success remains debated.\n*   **Imaging Markers:** Neuromuscular ultrasound can detect structural changes in nerves and muscles at the same time as, or earlier than, conventional electrophysiological tests in SOD1 models.\n*   **Peripheral Autophagy:** Platelet Factor 4 (PF4) serves as a circulating neuroprotective regulator that restores proteostasis specifically in SOD1-driven ALS models.\n*   **Cellular Quality Control:** SGK1 has been identified as a target for modulating microglial phagocytosis, with its inhibition offering survival benefits in SOD1-G93A models.\n*   **Cross-Pathology:** NOP56 downregulation is an early feature of SOD1-G93A models, suggesting a broader involvement in motor neuron protein homeostasis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Glabridin (Glab), a natural flavonoid derived from licorice, has been shown to mitigate stress-related damage due to its antioxidant properties. This study aims to assess the impact of Glab on OS-induced damage in the bovine immortalized cell line (BIECs-21), validate its effectiveness in vivo, and elucidate the underlying mechanisms. The in vitro OS model of BIECs-21 was established using 400 \u03bcM H2O2. The study evaluated cell viability, lactate dehydrogenase (LDH) activity, oxidative markers, inflammatory responses, and apoptosis in BIECs-21 under various treatment conditions. Additionally, the effects of Glab were investigated in a murine model of experimental colitis induced by dextran sulfate sodium (DSS). Glab improved cell viability, reduced LDH release, and mitigated the adverse effects of H2O2 on total anti-oxidation capacity (T-AOC), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) levels. qRT-PCR analysis revealed that H2O2 exposure resulted in decreased expression of nuclear factor erythroid 2-related factor 2 (Nrf2), superoxide dismutase 1 (SOD1), NADPH quinine oxidoreductase-1 (NQO1), and heme oxygenase-1 (HO-1), while it increased the expression of nuclear factor-kappa B (NF-\u03baB), tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-6 (IL-6), and interleukin-8 (IL-8), ultimately leading to apoptosis in BIECs-21. Notably, Glab supplementation partially reversed these effects. Similar benefits of Glab were observed in a DSS-induced colitis mouse model. Glab reduces OS-induced apoptosis in vitro and in vivo by enhancing antioxidant capacity and reducing inflammation.\n\nID: 42489267\nTitle: A Blood-Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN-Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1.\nAbstract: Peripheral factors that systemically regulate amyotrophic lateral sclerosis (ALS) have remained elusive-until now. Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n\nID: 42484074\nTitle: SOD1-lowering therapy for patients with wildtype SOD1-ALS: a case report.\nAbstract: Background and Objectives: To describe clinical and biomarker experience using an SOD1 antisense oligonucleotide (ASO) in a patient with non-SOD1 amyotrophic lateral sclerosis (ALS). Methods: Case report. Results: In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease. The time from symptom onset to death was 9\u2009months. Discussion: While treatment was initiated relatively late (\u223c7\u2009months) after symptom onset and follow-up duration was short, the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.\n\nID: 42479071\nTitle: Effects of six weeks of hypoxia and hypoxic SIT on oxidative stress and myokine responses in skeletal muscle of high-fat-fed ApoE-/- mice.\nAbstract: Atherosclerosis-induced oxidative stress drives skeletal muscle myopathy in peripheral artery disease, yet the combined effects of hypoxia and hypoxia sprint interval training (SIT) remain unclear. The present study was designed to evaluate how a six-week regimen of hypoxia exposure and SIT influences redox balance and myokine production in the skeletal muscle of high-fat diet (HFD) (21% fat, 1.5% (w/w) cholesterol; 43% (w/w) sucrose-free carbohydrate, 4.554\u00a0kcal/g)-fed atherosclerotic ApoE-/- mice. Forty male ApoE-/- mice fed a HFD were randomly assigned to four groups: Control-Normoxia, Control-Hypoxia, SIT-Normoxia, and SIT-Hypoxia. The hypoxia protocol involved exposures to 11.2% oxygen three times (40\u00a0min each) per week. Key assessment parameters included plasma lipid profiles, skeletal muscle reactive oxygen species (ROS), protein carbonyls, key components of the Nrf2 antioxidant pathway, glutathione metabolism, and myokine-related markers. Compared with the control group, both hypoxia and SIT-Normoxia significantly reduced levels of ROS, protein carbonyls, and Vegfa165 mRNA expression in the skeletal muscle. Hypoxia alone enhanced the levels of GSH-synthesizing enzymes and promoted myokine production. SIT-Normoxia improved plasma lipid profiles, activated the Nrf2 pathway, enhanced the GSH system, and upregulated myokines. SIT under hypoxia further reduced ROS and Vegfa165 while increasing plasma HDL-C and levels of SOD1 protein in the skeletal muscle, but failed to synergistically activate the Nrf2 pathway or enhance GSH production. Paradoxically, both intervention combinations suppressed the mRNA expression of myokine precursor Fndc5, BAIBA-synthesizing enzyme Hadh and Hadha. Overall, six weeks of isolated hypoxia exposure or SIT training independently reduced oxidative stress and promoted beneficial myokine responses in the skeletal muscle of ApoE-/- mice fed a HFD. The wild-type (WT) mice fed a low-fat diet (LFD) was included to validate successful induction of hyperlipidemia, vascular remodeling, and skeletal muscle oxidative stress in ApoE-/- mice after six weeks of HFD feeding.\n\nID: 42469634\nTitle: Secretory leukocyte protease inhibitor (SLPI) attenuates TLR4/NF-\u03baB-mediated neuroinflammation in amyotrophic lateral sclerosis: a candidate molecule associated with neuro-pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons. While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.\n\nID: 42467070\nTitle: Pivotal Factors in Breast Cancer Molecular Subtypes Apoptosis Induction by ELF-EMF; Ki-67, ROS Level, HER-2, and SODs.\nAbstract: Although increasing research has shown that extremely low-frequency electromagnetic fields (ELF-EMFs) specifically trigger PCD through the elevation of ROS levels in cancer cells, there is no adequate evidence to determine the exact mechanisms of this phenomenon. The antioxidant machinery may play a crucial role in this area; however, this has been neglected in previous research. The main aim of this study was to assess the effect of ELF-EMF exposure (5\u2009days, 1\u2009Hz, 100\u2009mT, 2\u2009h/day) on ROS levels, expression levels of antioxidant genes, and apoptosis induction in different breast cancer molecular subtypes with different p53 statuses. DCFH-DA results revealed that the ROS level increased in all three cell lines (SKBR-3, MDA-MB-231, and MCF-7); this increase was much greater in SKBR-3 (up to 5-fold compared to its sham exposure). This result was concurrent with the annexin V/PI results; SKBR-3\u2009cells showed much more apoptosis induction (about 78%), compared with the others (22% or 11% in the other two cells). On the other hand, the mRNA expression level of SOD1 and SOD2 increased significantly in the MDA-MB-231, in addition to these two genes, the expression level of SOD3 and GSR increased in the MCF-7\u2009cells but not in the SKBR-3. Taken together, our results confirmed that ELF-EMF induced ROS-dependent apoptosis, especially in HER-2-enriched breast cancer cells (the SKBR-3), in a p53-independent manner. Other molecular subtypes (MDA-MB-231 as TNBC, or MCF-7 as luminal A) showed resistance against the ROS level increasing and subsequent apoptosis induction by using antioxidant genes, especially SOD1.\n\nID: 42465739\nTitle: Development and efficacy of ex vivo expanded autologous regulatory T cells for the treatment of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited therapeutic options, in which neuroinflammation critically drives disease progression. Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.\n\nID: 42458007\nTitle: Oligonucleotide-siRNA conjugate for SOD1 amyotrophic lateral sclerosis: a phase 1 trial.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease partly caused by gain-of-function mutations in superoxide dismutase 1 (SOD1). Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS.

However, the global transcriptomic landscape underlying stress-induced hepatic injury remains incompletely understood. In this study, we employed a methionine-choline-deficient (MCD) diet-induced murine model to characterize the phenotypic and transcriptomic alterations associated with liver injury. Male C57BL/6J mice were fed either a control or MCD diet, and hepatotoxicity was assessed by survival analysis, body and liver weight measurements, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, histopathological examination, RNA sequencing, quantitative real-time PCR (qRT-PCR), and tumor necrosis factor-alpha (TNF-\u03b1) enzyme-linked immunosorbent assay (ELISA). MCD feeding markedly reduced survival and body weight while inducing hepatomegaly and significant elevations in serum ALT and AST, indicating severe hepatocellular injury. Histopathological analysis demonstrated hepatic steatosis, hepatocellular ballooning, and lobular inflammation without histological evidence of fibrosis. Transcriptomic profiling revealed extensive gene expression remodeling, characterized by activation of inflammatory pathways, enrichment of MAPK-related signaling, dysregulation of lipid metabolism, suppression of antioxidant defense systems, impairment of cytochrome P450-mediated detoxification, and upregulation of apoptosis-associated genes. qRT-PCR further validated the differential expression of representative genes involved in inflammatory signaling (Tlr4, Nfkb1, Nlrp3, and Casp1), MAPK signaling (Fos), xenobiotic metabolism (Cyp4f18), lipid metabolism (Apoa4 and Lpl), extracellular matrix remodeling (Mmp12), and oxidative stress responses (Sod1 and Gstp1). In addition, elevated serum TNF-\u03b1 levels provided protein-level evidence supporting activation of the TLR4/NF-\u03baB/TNF-\u03b1/NLRP3 inflammatory axis. Although fibrosis-associated transcriptional responses were detected, the absence of histological fibrosis suggests transcriptional priming of fibrogenic pathways rather than established fibrogenesis. Collectively, these findings provide a transcriptomic framework linking oxidative stress, impaired detoxification, inflammatory activation, and stress-responsive signaling to MCD-induced hepatic injury. The MCD model provides a valuable experimental platform for characterizing hepatic stress-response transcriptomes and for generating hypotheses that can subsequently be evaluated in environmentally relevant toxicological models. Nevertheless, caution should be exercised when extrapolating these findings to obesity-associated human MASLD, as the MCD model lacks key metabolic features of the human disease, including obesity and insulin resistance. Therefore, the present findings should be interpreted primarily as transcriptomic signatures of stress-induced hepatic injury rather than as a direct representation of the pathophysiological processes underlying human obesity-associated MASLD.\n\nID: 42450273\nTitle: Microvesicle-Derived Redox Signatures as Mediators of Endothelial Dysfunction in Diabetes.\nAbstract: Chronic hyperglycemia and excessive reactive oxygen species (ROS) production are defining features of endothelial dysfunction, a key driver of diabetic vascular complications such as diabetic nephropathy. Microvesicles (MV-enriched fraction), a subtype of extracellular vesicles, and the stress-responsive antioxidant protein Sestrin2 (SESN2) have emerged as important contributors to these processes. This study investigated the role of the MV-enriched fraction in endothelial cell communication under diabetic conditions, with a particular focus on oxidative stress signaling. To model diabetic injury, EA.hy926 endothelial cells were treated with methylglyoxal (MGO), and the resulting MV-enriched fraction was isolated and then applied to two recipient models: na\u00efve endothelial cells and SESN2 knockdown (KD) cells. Protein expression of key antioxidant markers, including endothelial nitric oxide synthase (eNOS), was assessed by Western blot. Nitric oxide (NO) bioavailability was quantified via nitrite measurement using 2,3-diaminonaphthalene (DAN), while mitochondrial and cytosolic ROS levels were evaluated using MitoSOX and dihydroethidium (DHE), respectively. Results demonstrated that the MV-enriched fraction derived from diabetic conditions triggers a complex antioxidant response in healthy endothelial cells, characterized by upregulation of SESN2, superoxide dismutase 1 (SOD1), and heme oxygenase-1 (HO-1). This suggests a compensatory mechanism that mitigates oxidative stress. Notably, SESN2 KD cells exhibited increased ROS production and reduced NO levels upon MV treatment, underscoring the essential role of SESN2 in maintaining redox homeostasis. Overall, this study highlights the dual role of the MV-enriched fraction as a mediator of both protective and detrimental redox signaling in diabetic endothelial dysfunction and suggests potential therapeutic targets for managing diabetic vascular complications.\n\nID: 42450113\nTitle: Serum Copper-to-Zinc Ratio and Oxidative Stress Are Associated with Anemia in Older Adults with Cardiovascular-Kidney-Metabolic Syndrome.\nAbstract: Chronic oxidative stress is a molecular hallmark of cardiovascular-kidney-metabolic (CKM) syndrome, yet its contribution to CKM-associated anemia beyond erythropoietin deficiency and iron restriction is poorly characterized. The serum copper-to-zinc (Cu/Zn) ratio reflects impaired Cu/Zn-SOD1 antioxidant capacity and inflammatory trace-element imbalance, but its relationships with circulating redox biomarkers and its hematological relevance in CKM syndrome has never been explored in a community-dwelling cohort of older adults. We analyzed 2391 NHANES 2011-2016 participants \u2265 50 years of age with CKM stage I-IV. To explore whether the serum Cu/Zn ratio was associated with oxidative stress and immunomodulatory biomarkers as well as with the odds of anemia, we used survey-weighted Spearman correlations, linear regression (outcome: hemoglobin), and logistic regression (outcome: anemia); multivariate models were adjusted for a panel of antioxidant or immunomodulatory biomarkers (selenium, vitamin D), pro-oxidant biomarkers (lead, cadmium, cotinine, uric acid), red cell distribution width (RDW) as a composite biomarker of erythrocyte stress, neutrophil-to-lymphocyte ratio (NLR), CKM stage, and comorbidities. The molecular targets of the nine biomarkers were mapped onto a protein-protein interaction network using the STRING database v12.0 to contextualize regression findings within a systems biology framework. Anemia was present in 205 participants (8.6%). The Cu/Zn ratio was inversely correlated with the antioxidant marker selenium (r = -0.19; p < 0.001) and positively correlated with the pro-oxidant markers RDW (r = +0.21; p < 0.001) and cadmium (r = +0.10; p < 0.001), consistent with its role as a hub within the CKM redox network. In fully adjusted models, a higher Cu/Zn ratio was independently associated with prevalent anemia (OR = 2.94; 95% CI: 1.61-5.37) and lower hemoglobin (\u03b2 = -0.55 g/dL); among included biomarkers, selenium and cadmium were independently protective (OR = 0.76 per 10 \u00b5g/L and 0.23 per \u00b5g/dL, respectively), and RDW and uric acid were independently harmful (OR = 2.20 per 1% and 1.33 per mg/dL, respectively). The Cu/Zn ratio correlated with both antioxidant depletion and pro-oxidant accumulation in CKM syndrome and was independently associated with anemia within this oxidative network. Together with selenium, cadmium, RDW, and uric acid, it defines an oxidative stress-driven hematological pathway that may contribute to the development and progression of anemia in patients with CKM syndrome.\n\nID: 42447970\nTitle: Human umbilical cord-derived mesenchymal stem cells ameliorate muscle dysfunction and metabolic dysregulation in the CuZnSOD null mouse model of sarcopenia.\nAbstract: Age-related sarcopenia is a progressive skeletal muscle disorder driven by oxidative stress and metabolic dysregulation. Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.\n\nID: 42447123\nTitle: Neuromuscular ultrasound as a biomarker in the SOD1 mouse model of amyotrophic lateral sclerosis.\nAbstract: A progression marker that indicates early disease-related changes and treatment responses in the to date incurable neurodegenerative disease amyotrophic lateral sclerosis (ALS) is highly desirable. Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.\n\nID: 42442802\nTitle: The Role of Genetic Alterations in the Emergence of Alzheimer's Disease in Down Syndrome: A Review.\nAbstract: Down syndrome (DS), the most common chromosomal disorder, is associated with an accelerated aging process, increasing the risk of early-onset Alzheimer's disease. This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers.\n\nID: 42442304\nTitle: Amelioration of obesity-induced testicular dysfunction and structural damage by ganoderma lucidum polysaccharides and triterpenoids in rats: Correlation with Nrf2-mediated antioxidant response.\nAbstract: Obesity is a global health crisis and a critical risk factor for male infertility, impairing testicular structure and function through hormonal imbalance and oxidative stress. Current therapeutic strategies are often unsatisfactory due to limited efficacy or adverse effects. This study investigated the protective effects and potential molecular mechanisms of Ganoderma lucidum (GL) polysaccharides and triterpenoids against testicular injury in high-fat diet-induced obese male rats. After 12-week GL intervention, reproductive function in obese male rats showed improvement: GL increased litter size, improved sperm motility, reduced sperm DNA fragmentation, and restored serum testosterone, inhibin B, and leptin levels. It also alleviated testicular histopathological damage, downregulated PPT1, and maintained vimentin expression. Notably, GL facilitated delayed fertility recovery and showed a trend toward improved cumulative reproductive success, although fixed-time pregnancy rates were not significantly changed. Mechanistically, GL is associated with enhanced Nrf2 pathway activity, increased SOD1, HO-1, NQO1, and GPX4 levels, and decreased MDA and ROS accumulation, thereby attenuating oxidative stress. It preserved mitochondrial integrity, suppressed germ cell apoptosis (downregulating Bax and caspase-3, upregulating Bcl-2), and promoted cell proliferation. These findings indicate that GL polysaccharides and triterpenoids effectively ameliorate obesity-induced testicular dysfunction, and these beneficial effects are associated with Nrf2-mediated antioxidant responses, mitochondrial homeostasis, apoptosis regulation, and hormonal balance. GL may serve as a promising candidate for obesity-related male infertility.\n\nID: 42437952\nTitle: NOP56 is essential for mammalian generation and maintenance of multiple central nervous systems, associated with SCA36 pathology.\nAbstract: NOP56, a core nucleolar component involved in small nucleolar ribonucleoprotein assembly, has been genetically implicated in spinocerebellar ataxia type 36. However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097.\n\nID: 42432986\nTitle: Mitoquinone Prevents Cardiac Dysfunction by Normalizing Mitochondrial ROS and Calcium Handling in Acute Myocardial Infarction.\nAbstract: Acute myocardial infarction (MI) is the leading cause of heart failure (HF). However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI. Male Wistar rats were divided into four experimental groups: Sham, Infarct, Sham+MitoQ, and Infarct+MitoQ. MitoQ was administered orally (8\u2009mg/kg/dia) for 7\u2009days. Hemodynamic parameters, infarct area, papillary muscle contractility, cardiomyocyte mechanics, Ca2+ transients, and total and mitochondrial superoxide (DHE and MitoSOX) were assessed. After 7\u2009days of MI, rats exhibited impaired contractility, altered inotropic response to extracellular Ca2+, cardiomyocyte hypertrophy, and increased total and ROSm. MitoQ prevented body weight loss and significantly improved hemodynamic parameters compared to the Infarct group. In papillary muscles, MitoQ restored basal isometric force and the inotropic response to extracellular Ca2+. In cardiomyocytes, it attenuated hypertrophy, preserved shortening, and reduced ([Ca2+]i) transient amplitude. MitoQ significantly decreased total and mitochondrial O2\u2022- production. It selectively reduced NOX1 expression under simulated conditions but did not significantly affect NOX2, SOD1, or catalase expression in the context of MI. MitoQ prevented contractile dysfunction, suggesting that mitochondrial oxidative stress plays a decisive role in myocardial dysfunction during the acute phase of MI. Targeting antioxidant therapy to the mitochondria represents a promising strategy for preventing post-infarction heart failure and opens new perspectives for the development of more effective interventions in the treatment of cardiovascular diseases.\n\nID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the \u03b11 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.\n\nID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.\n\nID: 42425334\nTitle: Comparative screening of Amur tiger cytokines identifies IL-15 as a cytoprotective candidate against feline panleukopenia virus infection.\nAbstract: Comparative studies of species-derived cytokines remain limited in endangered carnivores. We cloned six immune-related cytokines from Amur tigers (Panthera tigris altaica), with sequence analysis revealing >90% identity across Felidae. Among all tested cytokines, IL-15 demonstrated superior and sustained lymphocyte-stimulatory activity at 200\u202fng/mL. To investigate antiviral potential, F81\u202fcells were pretreated with IL-15 and challenged with feline panleukopenia virus (FPV). Mechanistic studies revealed that IL-15 attenuated virus-induced apoptosis by modulating key regulatory proteins: downregulating pro-apoptotic factors (Bax, Caspase3/9, p53, Cytc) while upregulating anti-apoptotic Bcl-2. Additionally, IL-15 preserved mitochondrial integrity by maintaining membrane potential, enhancing fusion proteins (MFN1/MFN2), and suppressing fission protein Drp1. IL-15 also strengthened cellular antioxidant defenses through increased SOD1/SOD2 expression, significantly reducing reactive oxygen species (ROS) accumulation. These protective effects persisted for 48\u202fh post-infection, demonstrating sustained cytoprotective effects. These findings reveal species-specific IL-15-mediated antiviral mechanisms within the Felidae family and provide comparative insights into how immune defenses are optimized in species with constrained evolutionary history, with implications for understanding carnivore immune evolution and conservation medicine.\n\nID: 42419058\nTitle: Redox Imbalance and Impaired Protein Clearance Drive Chronic Liver Injury in Biliary Atresia.\nAbstract: Excessive or uncontrolled generation of reactive oxygen species (ROS) is closely associated with the development of liver diseases. However, direct evidence linking oxidative stress to impaired hepatic function in human biliary atresia (BA) remains limited. To address this, we performed bulk RNA sequencing to investigate (1) alterations in hepatic oxidative stress and antioxidant defense mechanisms and (2) transcriptomic changes associated with impaired hepatic function in BA. Total RNA was extracted from liver samples of patients with BA and non-BA cholestasis. Bulk RNA sequencing and transcriptomic analyses were performed, focusing on redox-related pathways and genes linked to hepatic function. Dual oxidases 1 and 2 were significantly upregulated in BA. In contrast, key ROS-metabolizing enzymes such as catalase, glutathione synthetase, and superoxide dismutase 1 and 2 were downregulated, indicating redox imbalance in BA livers. Excessive ROS can lead to the denaturation of cellular proteins and damage to organelles, which are normally degraded via autophagy and proteasomes. However, both autophagy and proteasome functions were impaired in BA, contributing to sustained inflammation and further ROS production. Transcriptomic analyses also revealed repression of core liver transcription and splicing factors, indicating injury-associated alterations in hepatic transcription programs. BA is characterized by a redox imbalance and dysfunctional protein clearance, forming a vicious cycle of ROS accumulation and inflammation. These changes likely contribute to liver fibrosis and the progressive loss of hepatic function in BA.\n\nID: 42406382\nTitle: Antisense Oligonucleotide Tofersen Distribution in the Central Nervous System of SOD1-ALS Autopsy Tissue Donors.\nAbstract: Tofersen is a disease-modifying antisense oligonucleotide therapeutic for people living with SOD1-amyotrophic lateral sclerosis (SOD1-ALS). Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues.\n\nID: 42402967\nTitle: Hypoxia-preconditioned dental pulp stem cells alleviate acetaminophen-induced liver failure via promoting MYC-HIF1A/HIF-1\u03b1-BNIP3-mediated mitophagy.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is a prevalent clinical liver condition caused mostly by oxidative stress and mitochondrial damage. Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot.\n\nID: 42399593\nTitle: Early and severe masticatory muscle involvement in SOD1-ALS: a case report with biomarker-clinical dissociation.\nAbstract: \n\nID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n\nID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n\nID: 42397005\nTitle: Covalent Modulation of Protein Misfolding and Aggregation Processes in the Context of Neurodegenerative Diseases.\nAbstract: Misfolded protein aggregates represent major histopathological hallmarks of neurodegenerative diseases, differing in the structural components and brain regions affected. Furthermore, the formed assemblies act as key players in developing and fostering neurotoxic processes, with distinct mechanisms depending on the stage of the amyloid cascade. Particularly, the oligomer intermediates are now considered as the main drivers of neurotoxicity, thus requiring an early antiaggregant therapeutic intervention to achieve a significant neuroprotective efficacy. Among different strategies, direct interaction at early stages preventing aggregation is quite intricate due to the considered undruggability of misfolded monomers. In this context, a covalent approach targeting specific functional nucleophilic residues within disordered proteins can offer an intriguing opportunity to overcome these weaknesses. Therefore, in this review, we outline covalent modulators of misfolding and aggregation processes reported to date, referring to the major misfolded proteins in the neurodegenerative context (i.e., \u03b2-amyloid, tau, \u03b1-synuclein, and superoxide dismutase 1) to highlight their potential both as valuable pharmacological tools or therapeutic perspectives.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42390843\nTitle: Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis.\nAbstract: Superoxide dismutase 1 (SOD1), a copper-dependent antioxidant, is essential for redox homeostasis, and its decline drives renal senescence and fibrosis. However, the mechanisms linking profibrotic signaling to SOD1 inhibition remain unclear. Here, we identified a pathological copper-COMMD1-SOD1 axis in which intracellular copper overload paradoxically suppressed SOD1 activity. In kidney tissues from chronic kidney disease (CKD) patients and complementary in vivo and in vitro fibrotic models, we consistently observed a reduction in SOD1 activity accompanied by elevated intracellular copper levels.\u00a0Lowering intracellular copper levels restored SOD1 activity, suppressed reactive oxygen species (ROS) accumulation, and alleviated cell senescence and fibrosis. Mechanistically, pathological copper overload impaired SOD1 homodimerization, the essential final step in its activation. We identified copper metabolism MURR1 domain containing 1 (COMMD1) as a key copper-sensitive mediator of this process. Copper overload acted upstream, simultaneously upregulating COMMD1 expression and enhancing its binding affinity to SOD1. This enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function. Collectively, these findings redefined the regulatory role of copper in SOD1 activity and uncovered a previously unrecognized mechanism by which pathological copper overload paradoxically suppressed SOD1 activity via COMMD1-dependent disruption of SOD1 homodimerization, providing new insight into the pathophysiology of copper dyshomeostasis-associated diseases.\n\nID: 42387584\nTitle: SGK1-mediated deficits in microglial phagocytosis drive pathological progression in amyotrophic lateral sclerosis.\nAbstract: Alterations in microglial function and transcriptomic profiles are major pathological hallmarks of amyotrophic lateral sclerosis (ALS). However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.\n\nID: 42385849\nTitle: Quercetin and carvacrol act synergistically to inhibit Candida albicans biofilms in vitro via membrane disruption and oxidative stress.\nAbstract: Candida albicans biofilms are a major cause of device-associated infections and treatment failure due to high antifungal tolerance. Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200\u202f\u03bcg/mL (carvacrol) and 240\u202f\u03bcg/mL (quercetin) to 17\u202f\u03bcg/mL and 10.9\u202f\u03bcg/mL, respectively (FICI\u202f=\u202f0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by \u223c64.4% (vs. \u223c56.5% for carvacrol and \u223c51.5% for quercetin alone) and inducing apoptosis-like cell death with robust metacaspase activation supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established.\n\nID: 42385392\nTitle: Biological responses of human astrocytes (SVGp12) and glioblastoma (A172) cells to dendronized \u03b2-cyclodextrin molecular containers: Morphological and molecular insights.\nAbstract: The search for molecular containers that enhance the bioavailability of active substances has opened the development of functionalized \u03b2CD-based molecular containers. In this study, the effects of \u03b2CD-modified with dimethylolpropionic acid (Bis-MPA) dendrons (\u03b2CD-m2G and \u03b2CD-m3G) were evaluated in SVGp12 (non-tumor astrocytes) and A172 (glioblastoma) cells. The dendronized systems exhibited low cytotoxicity (>75% viability) even at high concentrations (90\u00a0\u03bcM, p\u00a0<\u00a00.05). Morphological analyses revealed lipid inclusion bodies (LIBs), suggesting that after intracellular uptake, the dendronized containers promote their formation. \u03b2CD-m3G occupies 12% of the cell volume in SVGp12 and 17% in A172 (p\u00a0<\u00a00.05). Ultrastructural evaluation showed increased smooth endoplasmic reticulum (SER), a finding consistent with enhanced lipid metabolism. Importantly, cell differentiation and endoplasmic reticulum stress, evaluated by the expression of Aquaporin-4 and calnexin, were not impaired (p\u00a0>\u00a00.05). A twofold increase in mGlu-5 expression (p\u00a0<\u00a00.001) was observed in both cell lines due primarily to the \u03b2CD-m3G container. Because neither container induces oxidative stress in the SVGp12 cell line, cell proliferation increases from 41% to 48% (p\u00a0<\u00a00.001) due to \u03b2CD-m2G and \u03b2CD-m3G, respectively. These cells also increased Caspase9 expression (p\u00a0<\u00a00.001), suggesting control of proliferation. However, \u03b2CD increased NRF2 expression by 4.3-fold (p\u00a0<\u00a00.0001) and the expression of SOD1, HMOX1, and PRDX1. \u03b2CD increases 1.8-fold-ROS in A172 cells (p\u00a0<\u00a00.001) versus control. 3.5-fold expression of NRF2 was observed in the presence of NAC (p\u00a0<\u00a00.001). These suggest that only \u03b2CD increases NRF2 and ROS as an adaptive response of A172 cells. The incorporation of amphiphilic dendritic groups enables efficient cellular uptake of \u03b2CD-dendronized containers.\n\nID: 42384769\nTitle: Carbon monoxide-releasing vesicles provide rapid and sustained inhibition of inflammatory pain in mice.\nAbstract: Carbon monoxide (CO) is an important modulator of chronic pain, but its clinical use remains limited. To enhance its therapeutic potential, we developed a vesicular CO-releasing system based on a carbonyl metallosurfactant (PCOL6) and soy phosphatidylcholine (SPC) and evaluated its physicochemical properties, as well as its in silico and in vivo effects on inflammation-induced nociception and muscle impairment in male C57BL/6 mice. The metallosomes exhibited a uniform size distribution, stability upon dilution, and a predominantly single membrane, indicating their suitability for therapeutic applications. Computational simulations revealed that PCOL6 can mix with phospholipids to form stable lamellar structures with thinner and more disordered bilayers than those of pure phospholipid membranes. In vivo experiments showed that acute administration of PCOL6/SPC vesicles inhibited complete Freund's adjuvant (CFA)-induced allodynia faster and longer than tricarbonyldichlororuthenium (II) dimer, Ru2Cl4(CO)6 (CORM-2). Repeated metallosome treatment was also more effective than CORM-2 at reducing allodynia, hyperalgesia, and inflammation-related muscle deficits. Both CO releasers normalized CFA-induced NOD-like receptor protein 3 inflammasome overexpression, increased heme oxygenase 1 (HO-1) and NAD(P)H quinone dehydrogenase 1 expression, and maintained elevated superoxide dismutase 1 levels in paw tissues; notably, HO-1 induction was greater in PCOL6/SPC-treated mice. These findings suggest that PCOL6/SPC metallosomes represent a promising therapeutic strategy for chronic inflammatory pain. Vesicles bearing a CO-releasing metallosurfactant (PCOL6) inhibit inflammatory pain.The analgesic effect of PCOL6/SPC is higher and lasts longer than that of CORM-2.PCOL6/SPC exerts anti-inflammatory and antioxidant effects.\n\nID: 42480869\nTitle: Macrophage responses to and elevated antibody levels against Chlorovirus ATCV-1 in ALS patients.\nAbstract: Acanthocystis turfacea chlorella virus 1 (ATCV-1) is a giant virus that is part of the human oral microvirome. Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease.\n\nID: 42457008\nTitle: Emerging Biomaterials Deliver Heat Shock Protein 90 Inhibitors to Enhance Therapeutic Efficacy in Cancer Therapy.\nAbstract: Innovative biomaterial-based drug delivery systems have shown notable promise in the clinical cancer treatment. However, the therapeutic effect for patients remains highly variable, and new strategies urgently need to be developed. Heat shock protein 90 (HSP90) is multifunctional molecular chaperones that are associated with various human diseases, including cancer, inflammation, and protein misfolding disorders. Notably, when combined with biomaterials, they can enable targeted and regulated tumor microenvironments, making progress in cancer treatment in recent years. Herein, the design concepts, therapeutic mechanisms, and synergistic applications of biomaterials combined with HSP90 inhibitors for cancer therapy will be comprehensively introduced. Additionally, this review will focus on the foundational concepts and structural type classification of HSP90 inhibitors, and summarize the application of biomaterials as inhibitor delivery carriers. Further, we systematically analyze the progress of HSP90 nanoinhibitors combined with other therapies for cancer therapy. Finally, we reasonably discuss the challenges inherent to the combined strategy of biomaterials and HSP90 nanoinhibitors, and the development prospects of new technologies in the engineered biomaterials for HSP90, aiming to provide a new paradigm for improving cancer treatment. STATEMENT OF SIGNIFICANCE: Accumulating evidence has demonstrated that heat shock protein 90 (HSP90)-based nanomedicines are emerging as promising platforms for tumor treatment. This review first categorizes the structural types and therapeutic mechanisms of HSP90 inhibitors, then summarizes the design and preparation strategies of various biomaterials conjugated with these inhibitors. Moreover, the applications of HSP90 nanoinhibitors in both monotherapy and rational combination strategies, as well as the present challenges and future directions for biomaterial-HSP90 inhibitor systems, are systematically discussed, providing new insights for nanotechnology-enabled cancer therapy.\n\nID: 42453524\nTitle: Therapeutic potential of adipose-derived stem cell transplantation in amyotrophic lateral sclerosis: A combined clinical case and preclinical study.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an inevitably fatal neurodegenerative disease with no adequate treatment. Transplantation of adipose-derived stem cells (ADSCs) may be an effective therapeutic strategy for delaying progression or restoring neurological function in ALS. We evaluated the safety and therapeutic efficacy of intravenous (i.v.) and intracerebral (i.c.) ADSC injection in a late-stage ALS patient and in a SOD1 transgenic (Tg) mouse model. Magnetic resonance imaging (MRI) and computed tomography (CT) were conducted to examine potential cerebral hemorrhage and tumor generation in the treated patient. In addition, maximal inspiratory pressure, maximal expiratory pressure, tidal volume, and respiratory rate were measured as indices of respiratory function. ADSC transplantation was safe, with MRI and CT showing no hemorrhage or tumorigenesis up to 12 months. The patient's Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score improved from 7 to 9 at 3 months and remained above baseline for 6 months. Respiratory function was preserved during this period. In SOD1 Tg mice, i.c. and i.v. ADSC infusion significantly prolonged survival (165.0 \u00b1 10.4 and 147.3 \u00b1 4.5 days vs. 129.7 \u00b1 3.9 days) and improved motor scores (P < 0.01). This preliminary finding suggests potential therapeutic feasibility, but further studies with larger cohorts are needed to confirm its safety and efficacy.\n\nID: 42410741\nTitle: In Vitro Skin-Protective Effects of Sumyong Nature, a Kimchi- and Soybean-Derived Fusion-Fermented Microbial Supernatant, in Human Keratinocytes: Involvement of MAPK-Related Signaling.\nAbstract: Sumyong Nature (SN) is a kimchi- and soybean-derived fusion-fermented microbial supernatant prepared from Lactobacillus acidophilus, Saccharomyces cerevisiae, Weissella cibaria, and Bifidobacterium longum. This study examined the in vitro effects of SN on UVB-induced damage and skin-related cellular responses in human keratinocytes. Cell viability assays, gene expression analysis, luciferase reporter assays, immunoblotting, scratch wound-healing assays, and LC-Q-TOF-MS analysis were conducted. SN showed no significant cytotoxicity in HaCaT or HEK293T cells at concentrations up to 75 \u03bcg/mL. In UVB-irradiated HaCaT cells, SN improved cell viability, suppressed MMP-1 expression, increased HAS-1 expression, and modulated UVB-responsive stress-related markers, including SOD-1, Nrf2, and HO-1. SN also promoted wound closure in keratinocytes and was associated with changes in NF-\u03baB-, AP-1-, CREB-, and MAPK-related signaling responses under the tested conditions. LC-Q-TOF-MS analysis tentatively identified several candidate constituents, including pectolinarin and aloeresin-related compounds. Collectively, these findings suggest that SN exerts multiple beneficial in vitro effects in keratinocyte-based assays, warranting further mechanistic investigation and validation in advanced experimental models.\n\nID: 42410102\nTitle: A changed landscape: five-year retrospective on the paradigm shift in genetic testing practices for ALS in Canada.\nAbstract: Offering genetic testing is increasingly recommended for all individuals with amyotrophic lateral sclerosis (ALS), particularly following the development of gene-targeted therapies, such as tofersen for SOD1-ALS. Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints. Broader use of multi-gene panel testing increased over time, coinciding with sponsored testing availability. 61% of respondents reported that Health Canada approval of tofersen directly influenced their practice. Predictive testing offerings increased from 37% in 2020 to 61% in 2025. Genetic testing practices in Canada shifted substantially during late-stage clinical development and following regulatory approval of a gene-targeted therapy (tofersen). Proactive planning during the clinical trial phase facilitated rapid, nationwide adoption. This study captures a key turning point in ALS care, illustrating how therapeutic breakthroughs can redefine national clinical standards.\n\nID: 42491038\nTitle: Progress in traditional Chinese medicine for chemotherapy-induced nausea and vomiting, based on the theory of \"Fuzheng Quxie\" and \"Hewei Jiangni\".\nAbstract: Chemotherapy-induced nausea and vomiting (CINV) is among the most prevalent adverse reactions in cancer treatment. It significantly diminishes the quality of life of patients and their treatment compliance. Traditional Chinese medicine (TCM) exhibits unique characteristics and potential for the prevention and treatment of CINV. This review summarizes the latest research progress on TCM for CINV, encompassing the theoretical foundation, mechanism of action, and clinical evidence. \"Fuzheng Quxie\" formulas (reinforcing healthy Qi and eliminating pathogenic factors) and herbs (e.g., Liu-Jun-Zi-Tang, ginseng) enhance the body's tolerance to chemotherapy by enhancing immunity, reducing inflammation and oxidative damage, and promoting tissue repair. \"Hewei Jiangni\" formulas (harmonizing the stomach and directing rebellious Qi downward), including Xiao-Ban-Xia-Tang, ginger, and external therapies (e.g., acupuncture, moxibustion, acupoint application) directly alleviate nausea and vomiting by regulating gastrointestinal motility, antagonizing emesis-related receptors, and inhibiting inflammatory pathways. Clinical research shows that combining TCM with conventional antiemetic regimens improves the control of delayed CINV and enhances patients' quality of life, while maintaining a favorable safety profile. However, current evidence remains limited by small sample sizes, insufficient mechanistic investigations, and lack of standardized treatment plans. Future research should prioritize high-quality and large-sample clinical trials and clarify its mechanism of action using modern scientific approaches, so as to promote the standardized and efficient application of TCM for the prevention and treatment of CINV.\n\nID: 42490066\nTitle: Trehalose: a potent enhancer of antioxidant responses in Brassica juncea L. under arsenic toxicity.\nAbstract: Arsenic contamination poses a major threat to crop productivity by impairing the photosynthetic machinery and inducing oxidative stress. This study explored the protective role of exogenous trehalose (25, 50, and 75\u2009mM) in mitigating arsenic-induced physiological and biochemical disturbances in Brassica juncea at 30, 60, and 90\u2009d after sowing. As stress significantly reduced photosynthetic pigments, including chlorophyll a (up to 72.91%), chlorophyll b (77.71%), total chlorophyll (56.49%), carotenoids (33%-43%), xanthophylls (42%-43%), and anthocyanins (38.82%). Concurrently, oxidative stress markers increased markedly, with malondialdehyde rising by 22%-46% and hydrogen peroxide (H\u2082O\u2082) by 12%-59%, indicating severe ROS-induced cellular damage. Foliar application of trehalose effectively alleviated these negative effects in a dose-dependent manner. Trehalose (75\u2009mM) showed the highest efficacy, enhancing chlorophyll a by 49%-88%, chlorophyll b by 56%-78%, total chlorophyll by 52%-66%, carotenoids by 42%-48%, and xanthophylls by 44%-58% compared to As-stressed plants. It also substantially improved the anthocyanin content and decreased MDA levels by 25%-29%, reflecting reduced lipid peroxidation and improved antioxidant defense. While H\u2082O\u2082 levels displayed some variability, trehalose consistently moderated its accumulation under As stress. Overall, trehalose significantly restored the pigment profiles, reduced oxidative damage, and enhanced stress tolerance, with 75\u2009mM emerging as the most effective concentration. These results highlight trehalose as a promising and eco-friendly strategy to improve plant resilience and productivity under arsenic-contaminated conditions.\n\nID: 42489288\nTitle: Rewiring Pyroptosis to Potentiate Cancer Immunotherapy via a Gasdermin D Agonist Bypassing Caspase-3.\nAbstract: Pyroptosis holds great promise for evoking robust anti-tumor immunity, but many pyroptosis induction strategies rely on caspase-3 (Casp-3) activation and face challenges of the immunosuppressive nature of apoptosis and the frequent silencing of gasdermin E (GSDME), a substrate of Casp-3, in tumors. Here, we report a strategy to rewire the pyroptotic pathway by bypassing Casp-3 to directly activate gasdermin D (GSDMD). We identify a small-molecule agonist, (E)-2,3-diiodobut-2-ene-1,4-diol (DIBDO), which undergoes deiodination to release iodide ions upon activation by the tumor-abundant nucleophile glutathione, thereby catalytically generating singlet oxygen and molecular iodine. This cascade induces oxidative damage that downregulates key mediators of caspase-9 and caspase-8 pathways, thereby down-regulating Casp-3 activation. This mechanism selectively triggers GSDMD-mediated pyroptosis, provoking robust immunogenic cell death and inflammatory cytokine release to reconfigure the tumor immune microenvironment. In murine tumor models, DIBDO enhances tumor infiltration of cytotoxic T cells and synergizes with checkpoint blockade therapy to suppress both primary and distal tumors. It can also serve as an in situ or exogenous vaccine to elicit potent and durable antitumor immunity. This work presents a paradigm-shifting approach to cancer immunotherapy by decoupling pyroptosis from Casp-3 dependence, offering a promising avenue to expand the scope of immunogenic cell death-based treatments.\n\nID: 42488833\nTitle: Huashi Baidu formula may attenuate adriamycin-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated ferroptosis.\nAbstract: Myocardial injury is a fatal adverse effect of adriamycin (ADR), which greatly limits its clinical application. Numerous studies have shown that Huashi Baidu formula (HBF) may exert a satisfactory effect on myocardial function repair. This study aims to reveal the underlying mechanisms and main bioactive compounds (BACs) of HBF against myocardial injury. Firstly, this study established an ADR-induced mouse model to assess the protective effects of HBF against myocardial injury. Subsequently, transcriptomic profiling was conducted to screen the differentially expressed genes among the HBF treatment, ADR-induced model, and normal control groups. Following the construction and analysis of protein-protein interactions, gene set enrichment analysis, and co-expression matrix, the key targets of HBF against myocardial injury were screened and further validated based on the ADR-induced mouse model. An integrative approach combining network mapping, molecular docking, and molecular dynamics simulation was performed to identify the representative BACs. Based on an ADR-induced myocardial injury mouse model, HBF significantly ameliorated myocardial injury by improving body weight loss, decreasing mortality, and rescuing severe cardiac fibrosis. A total of 361 ADR-related genes and 42 HBF therapeutic effect-related genes were identified with the thresholds P\u00a0<\u00a00.05 and fold change (FC)\u00a0>\u00a01.2 or\u00a0<\u00a00.833. Transcriptomic profiling-based networks demonstrated that the nuclear factor erythroid 2-related factor 2 (NRF2)-cyclic AMP-dependent transcription factor ATF-3 (ATF3)-sulfiredoxin-1 (SRXN1) axis-mediated ferroptosis was the key target of HBF against myocardial injury. In vivo validation showed that HBF treatment effectively inhibited serum enzymatic biomarkers of general myocardial injury (aspartate aminotransferase, lactate dehydrogenase, and creatine kinase), myofibroblast activity (transforming growth factor beta 1 and \u03b1-smooth muscle actin), inflammatory cytokines (tumor necrosis factor-\u03b1 and interleukin-6), oxidative damage (superoxide dismutase, malondialdehyde, accumulated iron content, and TUNEL-positive cells). Mechanically, HBF may restore the dysregulation of the NRF2-ATF3-SRXN1 signal axis, leading to inhibition of ferroptosis-associated protein expression. Emodin, rhein, and lactiflorin were identified as the underlying representative BACs of HBF against myocardial injury due to the strong binding affinities between candidate BACs and key targets [Kelch-like ECH-associated protein 1 (KEAP1), ATF3, SRXN1, system Xc- (SLC3A2/SLC7A11), glutathione peroxidase 4 (GPX4), ferroportin (FPN), glutathione synthetase (GSS)]. Molecular dynamics simulations further verified these findings, revealing the stable binding among the three components and the key targets. HBF may attenuate ADR-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated ferroptosis, and emodin, rhein, and lactiflorin are potential representative BACs.\n\nID: 42487205\nTitle: Revealing the Dualistic Toxicity of 1,4-Naphthoquinone in Earthworms: Cytotoxic Damage in Coelomocytes and Spectroscopic Insights Into Catalase Activation.\nAbstract: 1,4-Naphthoquinone (1,4-NQ) is an important organic chemical intermediate and a byproduct of polycyclic aromatic hydrocarbons degradation, harmful to soil organisms like earthworms. The underlying toxic mechanisms in earthworms remain unclear, but research highlights coelomocytes and catalase (CAT) as crucial for studying its cytotoxic and proteotoxic effects. 1,4-NQ caused cell membrane damage, mitochondrial injury, and oxidative stress. Studies using spectroscopy, isothermal titration calorimetry, and molecular simulation revealed that 1,4-NQ increased cell membrane permeability, indicated by higher LDH release and decreased Na+K+-ATPase activity, leading to dose-dependent cytotoxicity. It also induced oxidative damage via ROS production, impacting MDA levels, mitochondrial function, membrane potential, and intracellular calcium. Additionally, 1,4-NQ weakened antioxidant defenses, affecting CAT activity and GSH levels. It interacted with CAT, altering its structure to decrease hydrophobicity and loosen its framework, which exposed the catalytic site for better interaction with H2O2. Consequently, 1,4-NQ directly activated CAT, reducing free radicals and oxidative damage in coelomocytes. While CAT activity increased at the molecular level, an overall inhibition was observed in coelomocytes, suggesting that cellular oxidative stress counteracted the direct molecular activation through unknown mechanisms that warrant further investigation.\n\nID: 42487016\nTitle: Hypoxia as an amplifier of synovial inflammation in rheumatoid arthritis.\nAbstract: Inflammatory arthritis is characterized by neovascularization, leukocyte extravasation and synovial hyperplasia, leading to joint destruction and functional disability. Although increased synovial angiogenesis is a hallmark of synovial inflammation, efficiency of the oxygen supply to the synovium is poor, leading to a hypoxic gradient that impacts differential cellular responses. This hypoxic gradient occurs as infiltrating cells and cells that reside within the joint increase their metabolic demand beyond what the highly dysregulated vasculature can supply. This hypoxic environment favours an increase in reactive oxygen species, leading to oxidative damage that further promotes inflammation. In this adverse microenvironment, synovial cells adapt to generate energy and switch their cellular metabolism from a resting regulatory state to a highly metabolically active state, enabling them to produce essential building blocks to support their proliferation. This metabolic shift results in the accumulation of metabolic intermediates that function as signalling molecules, which further dictate the inflammatory response. However, the synovium is a complex multicellular tissue, and the specific cellular reliance on oxygen and metabolites differs across the synovium. Cellular demands depend on anatomical location, cell-cell interactions and competition for nutrients. Understanding the complex interplay between hypoxia-induced signalling pathways, oxidative stress and inflammatory responses will provide a better insight into the underlying mechanisms of disease pathogenesis.\n\nID: 42486854\nTitle: Loss of Atp8a2 drives neurodegeneration through the dysregulation of spatiotemporal phosphatidylserine externalization in mature neurons.\nAbstract: Phosphatidylserine (PS) asymmetry in plasma membranes is critical for cellular functions and serves as an apoptotic signal in many cell types. However, in mature neurons, the molecular mechanisms governing PS distribution, its precise regulation, and its functional significance beyond apoptosis and development remain poorly understood - particularly in the context of neurodegeneration. Here, we mapped the spatiotemporal dynamics of PS exposure in mature hippocampal neurons under physiological and pathological conditions using time-lapse imaging, revealing specific PS externalization hotspots at dendritic branching points. Using multiple in vitro and in vivo neurodegeneration models combined with molecular modeling, RNA interference, pharmacological interventions, and biochemical assays, we identified Atp8a2 as the primary regulator of PS asymmetry in mature neurons beyond its known roles in development. Notably, Atp8a2 expression levels - rather than its flippase activity alone - were essential for maintaining neuronal structural integrity and viability. Atp8a2 expression was significantly altered by neurotoxic stimuli and in multiple mouse models of neurodegeneration. Reduced Atp8a2 expression led to increased PS exposure, compromised neuronal architecture, and heightened susceptibility to degeneration, whereas Atp8a2 overexpression conferred substantial neuroprotection. The distinction between Atp8a2's enzymatic activity and expression level reveals a mechanism of neuronal homeostasis linking PS regulation to structural integrity and survival, possibly through association with cytoskeletal protein networks. Thus, Atp8a2 expression is a critical determinant of mature neuronal viability, presenting a potential target for neuroprotective strategies in neurodegeneration.\n\nID: 42486508\nTitle: Discovery of double 1,2,4-oxadiazole derivatives as promising nematicides.\nAbstract: Plant parasitic nematodes severely impair agricultural and forestry production due to the lack of effective nematicides, causing significant yield losses and economic damage. For discovery of new and efficient nematicidal agents, we developed a series of double 1,2,4-oxadiazole derivatives from our previous studies. Bioassays revealed that compounds B10 and B12 displayed 100% mortality against Bursaphelenchus xylophilus, Aphelenchoides besseyi and Ditylenchus destructor at 50\u2009\u03bcg\u2009mL-1. In particular, compound B10 was the most potent against B.\u2009xylophilus, showing a median lethal concentration (LC50) of 5.85\u2009\u03bcg\u2009mL-1, which outperformed the lead compound tioxazafen (LC50\u2009=\u2009180.02\u2009\u03bcg\u2009mL-1) by a clear margin. Preliminary mechanistic investigations indicated that B10 significantly suppressed the feeding and reproductive capacity of B.\u2009xylophilus, and induced substantial accumulation of intracellular reactive oxygen species, lipofuscin and lipids, accompanied by elevating malondialdehyde levels and suppressed activities of antioxidant-related enzymes, and then triggerred oxidative damage by disrupting redox homeostasis. Transcriptome analysis indicated that B10 strongly affected gene expression, with most the differentially expressed genes mainly associated with the neuroactive ligand-receptor interaction pathway. These results were further supported by quantitative reverse-transcription PCR analysis and acetylcholinesterase activity assays.

To better understand the mechanisms underlying spinal cord radiosensitivity, we developed a three-dimensional human spinal cord organoid model derived from human-induced pluripotent stem cells using a neuroectodermal differentiation protocol that closely mimics embryonic spinal cord development. Mature spinal cord organoids were exposed to a clinically relevant 2\u2009Gy dose of ionizing radiation, and subsequent assessments included evaluation of DNA damage, astrocytic response, and neuronal functionality. The organoids successfully recapitulated key features of spinal cord development, including neural differentiation, spontaneous electrophysiological activity, and functional maturation. Radiation exposure led to pronounced DNA double-strand breaks, particularly in SOX2-expressing progenitor cells. Astrocyte hyperplasia was evident through increased GFAP expression, indicating a reactive gliosis response. Electrophysiological analysis revealed a marked reduction in spike frequency and burst activity, indicative of impaired neuronal function. Although partial recovery was observed over time, functional deficits persisted, suggesting sustained damage. This human spinal cord organoid model offers a physiologically relevant platform for studying radiation-induced spinal cord injury and provides valuable insights into the cellular and functional consequences of radiation exposure. It holds significant potential for advancing neuroprotective strategies and therapeutic interventions targeting radiation-induced damage in the central nervous system.\n\nID: 42486374\nTitle: Integrated biomarker profiling reveals synergistic toxicity of pesticide-nanoparticle mixtures in zebrafish.\nAbstract: Aquatic ecosystems are increasingly exposed to contaminant mixtures rather than single compounds, creating complex interactions that remain poorly understood in ecotoxicology. Agricultural pesticides and engineered nanoparticles are among the most pervasive stressors, often detected together in surface waters due to intensive farming practices and widespread industrial use. Spirotetramat (a systemic tetramic acid insecticide), methoxyfenozide (an ecdysone agonist), and zinc oxide nanoparticles (ZnO-NPs) were focused on as representative co-occurring contaminants with potential joint effects on aquatic organisms. To investigate their combined impacts, adult zebrafish (Danio rerio) were exposed for 21\u202fdays to single, binary, and ternary mixtures under sublethal conditions, and multibiomarker profiling was applied to integrate neurotoxicity, oxidative stress, endocrine disruption, and apoptosis. Sustained acetylcholinesterase inhibition indicated persistent neurotoxic stress, while GST and CAT induction, biphasic GPx regulation, and elevated TBARS, protein carbonyls, and 8-OHdG revealed overwhelmed antioxidant defenses and cumulative oxidative damage. Vitellogenin induction, particularly in males, provided clear evidence of endocrine disruption, and caspase-3 activation highlighted apoptotic stress compromising organismal resilience. Integrated biomarker response scores identified ternary mixtures as most disruptive, while joint toxicity analysis revealed synergistic interactions beyond additive expectations. Collectively, these findings provide mechanistic evidence that pesticide-nanoparticle mixtures intensify neurotoxicity, oxidative stress, endocrine disruption, and apoptosis in zebrafish. Our results underscore that mixture-based biomarker integration is critical for capturing ecologically relevant outcomes and advancing risk assessment of emerging contaminant combinations.\n\nID: 42486007\nTitle: Genetic and epigenetic alterations in human gametes following cryopreservation: human evidence and insights from mammalian animal models.\nAbstract: Cryopreservation of gametes is an integral component of assisted reproductive technologies and fertility preservation; however, exposure to ultra-low temperatures may be associated with structural, genetic, and epigenetic alterations relevant to reproductive outcomes and offspring health. Although this review focuses on human spermatozoa and oocytes, it also incorporates mechanistic and translational evidence from mammalian animal models, including mouse, bovine, buffalo, caprine, and porcine studies, where direct human evidence remains limited. This distinction is essential, as several mechanisms of cryodamage have been defined experimentally in animal models, necessitating careful consideration of their applicability to human gametes. Spermatozoa and oocytes differ substantially in structural organization, metabolic activity, and regulatory mechanisms, resulting in distinct patterns of cryosensitivity. In spermatozoa, limited cytoplasmic volume, high membrane polyunsaturated fatty acid content, and compacted chromatin increase susceptibility to osmotic stress, oxidative damage, and membrane destabilization during freezing-thawing. Reactive oxygen species are central mediators of sperm cryodamage, contributing to DNA fragmentation, chromatin decondensation, altered protamine-histone balance, and epigenetic changes involving DNA methylation, histone modifications, and RNA profiles. Oocytes are particularly sensitive to temperature fluctuations, cryoprotectant exposure, and spindle disruption because of their complex cytoskeletal organization, mitochondrial activity, and dynamic epigenetic regulation. Cryopreservation-associated damage to the meiotic apparatus, mitochondrial function, and chromatin architecture may promote aneuploidy, DNA strand breaks, and transcriptomic alterations. Overall, this review summarizes current evidence on genetic and epigenetic alterations associated with gamete cryopreservation, highlights mechanisms of cryodamage, and discusses their translational and clinical relevance.\n\nID: 42485996\nTitle: Ecotoxicological effects of combined exposure to bifenthrin and polyethylene microplastics on the earthworm Eisenia fetida.\nAbstract: Bifenthrin (BF) is a widely used insecticide, and polyethylene microplastics (PE MPs) are emerging contaminants in agricultural soils. However, the combined ecotoxicological effects of BF and PE MPs on soil organisms remain poorly understood. In this study, a controlled soil exposure experiment was conducted in which earthworms (Eisenia fetida) were exposed to BF (10\u202fmg/kg) and/or PE-MPs (30 \u03bcm, 2.5\u202fg/kg) for 14 and 28 days. The ecotoxicological effects were evaluated using integrated biochemical, histopathological, and transcriptomic approaches. Molecular dynamics simulations revealed that BF could spontaneously adsorb onto PE surfaces, with an adsorption energy of -30.58\u202fkcal/mol. Specifically, co-exposure to BF and PE-MPs significantly elevated ROS, which was 3.5% higher than in the BF group, and markedly inhibited AChE activity, which was 12.2% lower than in the BF group after 28 days, indicating enhanced oxidative stress and neurotoxicity. Prolonged exposure suppressed key antioxidants, including superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), indicating a transition from adaptive response to oxidative damage. Integrated biomarker analysis showed the highest IBR under co-exposure, with positive EAI values of 0.213 and 0.191 after 14 and 28 days, respectively, confirming persistent synergistic toxicity. Histopathological observations confirmed aggravated tissue injury, particularly in the intestinal epithelium and muscle layers, under combined exposure. Transcriptomic analysis revealed that co-exposure induced broader transcriptional perturbations involving stress-responsive signaling, membrane-associated dysfunction, and detoxification transport pathways. Overall, PE-MPs amplify BF toxicity through synergistic interactions, highlighting the importance of considering pollutant co-exposure and carrier effects in ecological risk assessment of contaminated soils.\n\nID: 42485859\nTitle: Symbiosis modulates pharmaceutical toxicity and contaminant fate in the Azolla-Nostoc system.\nAbstract: Pharmaceutical contamination in aquatic environments frequently occurs as complex mixtures; however, the extent to which biological interactions modify the toxicity and fate of contaminants remains poorly understood. Here, we investigated the physiological, biochemical, ecotoxicological, and phytoremediation responses of Azolla filiculoides cultivated in the presence (A+N) or absence (A-N) of Nostoc flagelliforme exposed to hydroxychloroquine (HCQ), ivermectin (IVE), and azithromycin (AZI), applied individually across environmentally relevant to elevated exposure concentrations (0-200\u00a0\u03bcg\u00a0L-1) and in fixed-ratio mixtures (2\u00a0\u03bcg\u00a0L-1 per compound). IVE induced the strongest physiological disruption, impairing photosynthetic performance, increasing oxidative stress, and destabilizing nitrogen metabolism, whereas HCQ produced intermediate effects and AZI caused comparatively weaker responses. Symbiosis was associated with higher ecotoxicological thresholds for several physiological endpoints, with threshold values differing by up to two orders of magnitude between A-N and A+N plants. Compared with A-N plants, A+N plants generally maintained higher photosynthetic performance, lower oxidative damage, and higher nitrogen-related metabolite concentrations, including elevated NH4+, glutamate, glutamine, and total-N concentrations. Symbiosis was also associated with differences in pharmaceutical fate in a compound-specific manner. For AZI and IVE, enhanced removal efficiency coincided with lower tissue accumulation, whereas HCQ exhibited both greater removal and higher internal retention under symbiotic conditions. Collectively, these findings indicate that symbiosis modulates pharmaceutical responses, ecotoxicological sensitivity, and contaminant fate in a compound-specific manner, highlighting the importance of biological interactions in shaping ecotoxicological responses and pharmaceutical attenuation in aquatic plant-microbe systems.\n\nID: 42485855\nTitle: Pharmacological inhibition of GPR84 attenuates acute ovarian ischemia-reperfusion injury in mice via activation of AMPK and suppression of the NLRP3 inflammasome.\nAbstract: Ovarian ischemia-reperfusion injury (OIRI) causes oxidative damage, inflammation, and tissue destruction, frequently causing tissue damage and inflammation. Although G protein-coupled receptor 84 (GPR84) operates as a modulator of immune cell activation across numerous pathological contexts, its specific contributions to OIRI pathophysiology remain insufficiently characterized. We therefore examined whether pharmacological blockade of GPR84 confers protection against OIRI and delineated the operative signaling networks. Utilizing a murine model of bilateral ovarian ischemia followed by reperfusion, we administered either PBI-4050 or BGT-004 to evaluate therapeutic efficacy. Our analyses revealed pronounced GPR84 upregulation within ovarian tissues subjected to ischemic insult. Tissue fractionation experiments showed that GPR84 upregulation occurred predominantly in CD45\u207a leukocytes. Both antagonistic compounds substantially mitigated histological deterioration while attenuating lipid peroxidation (malondialdehyde accumulation), oxidative radical generation (nitric oxide), and neutrophil infiltration (myeloperoxidase activity), concomitantly enhancing antioxidant defense (superoxide dismutase function) and curtailing secretion of IL-1\u03b2 and IL-18. Additionally, treatment suppressed NOX-4 expression and thwarted NLRP3 inflammasome assembly, reflected in diminished NLRP3 protein abundance and reduced caspase-1 cleavage. GPR84 blockade also reduced gasdermin D cleavage, indicating suppression of pyroptotic cell death. Mechanistically, GPR84 blockade reinstated AMPK\u03b1 phosphorylation status and restored phosphorylation of the downstream AMPK substrate acetyl-CoA carboxylase; however, co-administration of the AMPK antagonist Compound C with BGT-004 nullified these protective actions, suggesting that AMPK signaling contributes to therapeutic efficacy. The Compound C mechanistic validation was performed using BGT-004, the selective GPR84 antagonist, to avoid confounding from PBI-4050's GPR40 agonist activity. These observations collectively suggest that GPR84 antagonism ameliorates OIRI through AMPK-dependent suppression of NLRP3 inflammasome activity, identifying this receptor as a candidate for further investigation in ischemia-reperfusion injury.\n\nID: 42485580\nTitle: A Wheat-Specific miRNA, tae-miR5048, Fine-Tunes Plant Architecture and Drought Resilience Through Targeting Multiple Kinase Genes.\nAbstract: MicroRNAs (miRNAs) are key regulators of plant development and stress adaptation. While conserved miRNAs have been extensively characterized, the agronomic roles of lineage-specific miRNAs in crops remain largely unexplored. Here, we demonstrate that tae-miR5048, a wheat-specific miRNA, functions as a master regulator concurrently modulating plant architecture and drought tolerance. Overexpression of tae-miR5048 enhanced early root growth, accelerated reproductive transition, and optimized plant architecture and grain morphology without compromising grain yield. Conversely, CRISPR/Cas9-mediated knockout of TaMIR5048 homoeologs impaired root development and delayed flowering, yet promoted vegetative growth and grain yield potential, revealing a bidirectional regulatory role. Cytological analysis showed that tae-miR5048 optimizes plant height, flag leaf size and grain dimension by fine-tuning cell proliferation and expansion in a tissue-specific manner. Moreover, tae-miR5048 confers drought resilience throughout the growth cycle by elevating osmolyte accumulation to maintain tissue water status and alleviating oxidative damage through suppression of ROS production and membrane lipid peroxidation. Mechanistically, degradome sequencing, RLM\u20115' RACE, and transient co\u2011expression assays demonstrated that tae-miR5048 directly targets and downregulates multiple kinase genes, including receptor-like protein kinases and mitogen-activated protein kinases, thereby modulating key signalling hubs post-transcriptionally. Transcriptome profiling further revealed that tae-miR5048 fine-tunes architectural traits by regulating cellular growth-related genes and enhances drought tolerance through activation of stress-responsive and proline biosynthesis pathways. Collectively, our findings establish tae-miR5048 as a central integrator that balances plant architecture and drought adaptation, providing the first functional evidence for a lineage-specific miRNA as a promising target for breeding climate-resilient wheat varieties.\n\nID: 42484169\nTitle: Effects of Pine Needle Accumulation on Tadpole Development, Oxidative Stress and Genetic Damage in Odontophrynus reigi (Anura: Odontophrynidae).\nAbstract: Large extensions of the Atlantic Forest in Brazil and Argentina have been replaced by monoculture tree plantations (mainly Pinus spp.). Small changes in the chemistry of pools where leaf litter tend to accumulate can have major effects on amphibian physiology and ecology. This work studied effects of pine needles on Odontophrynus reigi tadpoles. We exposed tadpoles to different concentrations of pine needles (0, 0.5, 1.5 and 2.5 g/L). In tadpoles, we determined: 1) morphological endpoints, 2) growth rate and development stage, 3) oxidative stress parameters (catalase, glutathione-S-transferase, lipid peroxidation (LPO) and protein oxidation (PO)) and 4) genetic damage (micronucleus, erythrocytes nuclear abnormalities and mitotic index). Dissolved oxygen (DO), pH, ammonia and total phenols (TP) were determined in water. As pine needle concentration increased, DO, pH and ammonium decreased in water, and TP increased. All morphological endpoints increased as pine needle increased, except body width that decreased. Oxidative damage had opposite effects: LPO decreased 50%, and PO had a 3-fold increase at 2.5 g/L. Catalase and glutathione-S-transferase enzymatic activities did not change significantly. Mitotic index increased with pine needle concentration. These physiological responses, likely driven by changes in water chemistry, suggest a potential long-term cost for individuals inhabiting pine monocultures.\n\nID: 42484079\nTitle: Effects of Different Duration of High-Fat Feeding on the NAD+/Sirtuins/PGC1alpha Axis in Relation to Oxidative Stress in Rat Skeletal Muscle.\nAbstract: This study examined the effects of varying durations of high-fat diet (HFD) exposure on oxidative stress and the NAD+/Sirtuins/PGC1alpha signaling pathway in rat skeletal muscle. Thirty-two male Sprague-Dawley rats were randomly assigned to either a control group or HFD groups with exposure periods of 4, 8, or 12 weeks. Outcome measures included body weight, inflammatory markers (IL-6, TNF-alpha, MCP-1), oxidative stress parameters (MDA, SOD, GSH), apoptotic activity, and protein expression levels of key components within the signaling pathway. The results demonstrated that body weight and systemic inflammation progressively increased with the duration of HFD intake. Markers of oxidative stress became significantly elevated by week 8 and further deteriorated by week 12, characterized by increased malondialdehyde (MDA) levels, diminished antioxidant capacity (reduced SOD and GSH), and enhanced apoptosis. A reduction in Sirt3 expression and increased acetylation of PGC1alpha were detected at 8 weeks, while by 12 weeks, dysregulation extended across the entire NAD+/Sirt1/PGC1alpha pathway. These alterations were associated with exacerbated oxidative damage. The findings suggest that the duration of HFD exposure plays a critical role in the development of skeletal muscle oxidative stress through progressive and time-dependent impairment of the NAD+/Sirtuins/PGC1alpha pathway. Key words High-fat diet \" Skeletal muscle \" Oxidative stress \" Obesity \" NAD+ \" PGC1-alpha.\n\nID: 42483214\nTitle: Diquat-induced organ toxicity: a focus on regulated cell death pathways and mitochondrial dysfunction.\nAbstract: Diquat (1,1'-ethylene-2,2'-bipyridyl, DQ) is a herbicide widely used for weed control in both agricultural and non-cultivated areas. Although its acute toxicity is lower than that of paraquat, its high-water solubility and stability in acidic and neutral environments contribute to its prolonged environmental persistence. As DQ gradually replaces paraquat in agricultural practice, the incidence of DQ poisoning has increased significantly. DQ poisoning typically results from accidental ingestion, suicidal intake, or improper agricultural handling. To date, no specific antidote is available, and the high mortality associated with DQ poisoning presents a critical challenge for clinical management. Accumulating evidence indicates that the toxicity of DQ is primarily attributed to its capacity to generate reactive oxygen species (ROS), leading to oxidative stress and subsequent oxidative damage to lipids, proteins, and DNA, ultimately resulting in multi-organ dysfunction, with the kidneys and intestines being the primary target organs. The pathogenesis of DQ poisoning involves multiple factors, including oxidative stress imbalance, regulated cell death, mitochondrial dysfunction, and disturbances in energy metabolism. This review systematically examines the physicochemical properties, metabolic characteristics, biodistribution, and target organ toxicity of DQ, with a particular focus on the interplay between excessive ROS production and mitochondrial dysfunction in the context of oxidative stress. Furthermore, we provide an in-depth discussion on the roles of regulated cell death-including pyroptosis, ferroptosis, and mitophagy-and metabolic dysregulation in DQ-induced toxicity. In addition, this review summarizes the classical signaling pathways involved in organ dysfunction, current therapeutic strategies, and potential intervention targets, thereby offering a theoretical framework and future research directions for the management of DQ poisoning.\n\nID: 42482671\nTitle: Quaternary Ammonium-Functionalized Membrane-Anchored Photosensitizer against Multidrug-Resistant Bacterial Infections.\nAbstract: The discovery of new antimicrobial medications has not kept up with the evolution of bacterial resistance, and infections with drug-resistant bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA), continue to pose a serious threat to global public health. Antimicrobial photodynamic therapy (aPDT), as an alternative strategy, produces reactive oxygen species (ROS) under light activation and kills drug-resistant bacteria through oxidative damage. Nevertheless, conventional photosensitizers (PSs) are limited by aggregation-caused quenching, inadequate bacterial selectivity, and off-target cytotoxicity. Quaternary ammonium salts (QASs) can preferentially accumulate on bacterial membranes through electrostatic interactions and disrupt the bacterial membranes. The quaternary ammonium PS PK4, reported here has a triphenylamine unit that enhances ROS production. Under white light irradiation, PK4 produces abundant ROS that oxidatively damage bacterial membranes, while exhibiting high photostability and minimal dark toxicity. In an MRSA-infected wound model, PK4-mediated phototherapy can reduce inflammation, accelerate wound healing, and enhance collagen deposition without systemic toxicity, providing a promising aPDT strategy for combating drug-resistant bacterial infections.\n\nID: 42482407\nTitle: Modulatory effects of hesperidin on rotenone-induced neurotoxicity in Drosophila melanogaster.\nAbstract: Neurodegenerative disorders are closely associated with oxidative stress, mitochondrial dysfunction, and apoptosis. Rotenone, a potent inhibitor of mitochondrial complex I, is widely used to model Parkinson-like pathology because it induces oxidative damage and selective loss of dopaminergic neurons. In the present study, Drosophila melanogaster was employed to investigate rotenone-induced neurotoxicity and to evaluate the protective potential of hesperidin, a naturally occurring flavonoid known for its antioxidant and anti-apoptotic activities. Exposure to rotenone resulted in reduced survival rates, impaired locomotion and climbing ability, elevated reactive oxygen species (ROS) levels, increased protein oxidation, and heightened caspase-3 activity, reflecting neurodegenerative changes. Notably, co-treatment with hesperidin mitigated these adverse effects by enhancing motor performance, decreasing oxidative stress markers, and suppressing apoptotic signaling. Collectively, these findings suggest that hesperidin offers significant protection against rotenone-induced neurotoxicity in D. melanogaster, highlighting its potential as a therapeutic candidate for neurodegenerative disorders.\n\nID: 42482175\nTitle: Grx2 deficiency accelerates BMSC senescence and senile osteoporosis via CD36 S-glutathionylation.\nAbstract: Senile osteoporosis (SOP) is driven largely by bone marrow mesenchymal stem cell (BMSC) senescence and mitochondrial dysfunction. S-glutathionylation is an important redox modification regulating mitochondrial homeostasis, yet its role in skeletal aging remains unclear. The objective of this study is to systematically investigate the role of Grx2 deficiency-mediated CD36 S-glutathionylation in BMSC senescence and SOP development. Grx2, p53, and p21 expression in human and mouse BMSCs were analyzed by immunohistochemistry (IHC), western blotting (WB), and polymerase chain reaction (PCR). Aging-related and ovariectomy-induced osteoporosis models were established in Grx2-/- mice for bone metabolism and senescence assessments. BMSC senescence, osteogenesis, and adipogenesis were evaluated by SA-\u03b2-Gal and WB, ALP/ARS staining, and ORO staining. Transcriptomic and S-glutathionylated proteomic analyses were performed to identify underlying mechanisms. Fatty acid uptake was quantified using two-color flow cytometry. DAG and MDA levels were measured to assess lipid overload and oxidative injury. Mitochondrial structure and function were evaluated by TEM, Mitotracker, qPCR, NAD+/NADH, ATP, ROS, JC-1, and Seahorse assays. The PI3K/AKT pathway was assessed by WB. Co-IP confirmed CD36 S-glutathionylation, and molecular docking predicted C272 as the key modification site. CD36-C272S mutation and Grx2 overexpression were applied to validate functional mechanisms in vitro and in vivo. Grx2 deficiency, in both male and ovariectomized female mice, accelerates bone loss, inhibits osteoblast formation without altering osteoclast function, and exacerbates BMSC senescence. Through integrated transcriptomic and S-glutathionylated proteomic analysis, we identified the fatty acid transporter CD36 as a critical downstream target of Grx2. Notably, Grx2 deficiency markedly increases the S-glutathionylation of CD36, which not only enhances its fatty acid uptake capacity, leading to the accumulation of toxic lipid metabolites and oxidative damage, but also impairs mitochondrial energy metabolism by inhibiting the PI3K/AKT signaling pathway. Overexpression of Grx2 or the C272S mutation in CD36, which disrupts its S-glutathionylation, can break this harmful cycle and inhibit BMSC senescence. Grx2 deficiency-mediated CD36 S-glutathionylation drives BMSC senescence and SOP, providing new insight into the redox regulatory mechanisms underlying skeletal aging.\n\nID: 42482001\nTitle: Melatonin and circadian regulation of inflammatory-oxidative pathways in pediatric neurological disorders.\nAbstract: Circadian rhythms are intrinsic 24-hour cycles that regulate nearly all aspects of human physiology and play essential roles in brain development, immune regulation, and redox balance. Adult studies have explored the links between circadian rhythms and neurological or metabolic diseases, but research in pediatric populations remains limited. In infants and children, circadian systems undergo rapid maturation, and this developmental window is particularly vulnerable to disruption from maternal, environmental, or endogenous factors. The aim of this review is to examine how circadian mechanisms intersect with inflammatory and oxidative pathways in pediatric neurological disorders, highlighting both mechanistic insights and therapeutic potential. We conducted a narrative review of PubMed/MEDLINE and complementary sources, covering studies published between January 2016 and March 2025, with relevant studies selected for detailed synthesis. Evidence shows that oxidative stress and inflammation are exacerbated by immature circadian control, with glial circadian clocks, clock genes, and cytokine-melatonin interactions playing important roles. Melatonin is frequently identified as a key circadian-regulated mediator in pediatric conditions, including hypoxic-ischaemic encephalopathy, autism spectrum disorder, metabolic encephalopathies, and sepsis. Preclinical and translational studies demonstrate that melatonin reduces oxidative damage, maintains mitochondrial function, and modulates immune responses, while early clinical data indicate that it is safe and holds promise as an adjunctive therapy. The review further emphasizes that circadian regulation of oxidative stress is shaped by maternal signals, melatonin in breast milk, and environmental exposures in neonates, particularly in preterm infants. Despite growing evidence, major gaps remain, including the lack of pediatric-specific chronotherapy trials, standardized dosing protocols, and time-stamped biospecimen studies. We suggest a feasible roadmap for future melatonin-based pediatric chronotherapy trials, linking mechanistic insights to clinical application. Overall, advancing circadian biology, particularly through melatonin, offers a promising avenue for pediatric neuroprotection and opens new directions for chronotherapy in vulnerable populations.\n\nID: 42481931\nTitle: Green-synthesized lanthanum nanostructures modulate redox balance and phytochemical responses in lead-stressed Zataria multiflora.\nAbstract: Lead (Pb) toxicity disrupts redox homeostasis and impairs phytochemical stability in medicinal plants; however, nanomaterial-based approaches to alleviate oxidative stress under Pb stress have not been extensively studied. In the present study, lanthanum-based nanostructures (La-based NCs) were prepared using an eco-friendly method employing Arabic gum and spermine, and their efficacy in alleviating Pb-stress-induced oxidative damage in Zataria multiflora was investigated. The plants were subjected to different levels of Pb contamination (0, 250, 500, and 750\u00a0mg/kg) and then treated with La-based NCs at doses ranging from 0 to 200\u00a0ppm. The effect of Pb toxicity (750\u00a0mg/kg) led to an increase in indicators of oxidative stress, including H\u2082O\u2082 and MDA, along with a significant decrease in the activity of phytochemicals and antioxidant response. Treatment with La-based NCs significantly improved these effects dose-dependently, showing the optimal dose at 100\u00a0ppm. At 100\u00a0ppm of La-based NCs treatment, oxidative damage was decreased by 40-60%, whereas antioxidant responses were stimulated by 35-70%. Simultaneously, metabolic stability was enhanced through the recovery of essential oils and related phytochemical characteristics. Particularly, La-based NCs stabilized with Arabic gum consistently showed greater activity than those stabilized with spermine, suggesting a stabilization-mediated influence on redox reactions and plant-NCs interactions. This study demonstrates that green-synthesized La-based NCs have potential applications as modulators of oxidative stress and antioxidants within the plant system under Pb stress.\n\nID: 42481908\nTitle: A Study on the Effects of Intranasally Administered Liquid Crystalline Nanoparticles Loaded with Salvianolic Acid B in Vascular Dementia.\nAbstract: Salvianolic acid B (SalB) is a bioactive polyphenol with therapeutic potential for vascular dementia (VD), but poor penetration across the blood-brain barrier (BBB) and low bioavailability restrict its clinical translation. To address these problems, a SalB-loaded liquid crystalline nanoparticle delivery system (SalB-LCN) was constructed and systematically characterized in terms of its physicochemical properties. Meanwhile, an intranasal administration strategy was employed to bypass the BBB, and the therapeutic effects of SalB-LCN on VD were systematically evaluated. The results showed that SalB-LCN possessed favorable morphology and sustained-release properties, enabling stable encapsulation and continuous release of SalB. In vitro experiments demonstrated that SalB-LCN exhibited good biocompatibility and could alleviate oxidative damage in neuronal cells. In a bilateral common carotid artery occlusion-induced rat model of VD, SalB-LCN significantly improved learning and memory abilities, alleviated hippocampal neuronal morphological damage, and exhibited good in vivo biosafety. Further studies showed that SalB-LCN markedly lowered reactive oxygen species levels, suppressed IL-1\u03b2 and IL-18 production in hippocampal tissues, and reduced cell death as well as lactate dehydrogenase activity. In addition, SalB-LCN also suppressed NLRP3/Caspase-1/GSDMD signaling. In conclusion, intranasal delivery of SalB-LCN improved brain delivery by facilitating transport across the BBB and conferred neuroprotection against VD through modulation of oxidative stress, inflammation, and NLRP3/Caspase-1/GSDMD signaling, highlighting its translational potential as a nanomedicine-based therapeutic strategy.\n\nID: 42480866\nTitle: Glutathione S-transferase gene family analysis and enzymatic properties of three selenium-responsive members from selenium hyperaccumulator Cardamine hupingshanensis.\nAbstract: Selenium is an essential trace element for plant growth and development; however, excessive selenium stress induces the accumulation of reactive oxygen species, leading to oxidative damage and inhibition of normal plant growth. Cardamine hupingshanensis is a selenium\u2011hyperaccumulating plant species endemic to China, exhibiting strong tolerance and high capacity for accumulation in high\u2011selenium environments. Glutathione S\u2011transferases (GSTs) are important enzymes involved in diverse metabolic processes and stress responses, yet systematic identification and functional characterization of the GST gene family in this species remain incomplete. In this study, a genome\u2011wide identification of the GST gene family in C. hupingshanensis was performed using bioinformatics approaches, and the phylogenetic relationships, gene structures, conserved motifs, physicochemical properties, and subcellular localizations were systematically analyzed. A total of 61 ChGST genes were identified and classified into eight subfamilies, with the Tau and Phi subfamilies being the most abundant. Three representative Tau subfamily genes (ChGSTU4-3, ChGSTU16-1, and ChGSTU24), which exhibit divergent tissue\u2011specific and selenium\u2011responsive expression patterns and belong to separate phylogenetic clades, were selected for subsequent functional characterization. Prokaryotic recombinant expression vectors were constructed via gene cloning, and the recombinant proteins were expressed in Escherichia coli and purified. The temperature and pH adaptability, metal ion responses, and enzymatic kinetic parameters of the fusion proteins were determined, and their antioxidant activities were evaluated using the disk diffusion method. In vitro enzymatic assays showed that all three fusion proteins exhibited high catalytic activity in the range of 30-50 \u00b0C and pH 7.0-8.0. Different metal ions exerted distinct regulatory effects on ChGST enzyme activity: Na+, K+, and Ca2+ had negligible effects, whereas the other tested ions showed various degrees of inhibition. The disk diffusion assay demonstrated that ChGSTU4-3, ChGSTU16-1, and ChGSTU24 protected bacterial cells from oxidative stress induced by hydrogen peroxide. This study delineates the basic characteristics and in vitro functions of the GST gene family in C. hupingshanensis, providing preliminary experimental evidence that may contribute to understanding the molecular basis of selenium tolerance in this species, as well as a theoretical reference for mining stress\u2011responsive genes and for the bioremediation of selenium\u2011contaminated environments.\n\nID: 42480690\nTitle: Bisphenol S disrupts neuronal morphogenesis in human neural cells by overactivating NMDA receptor-Ca2+ signaling.\nAbstract: Bisphenol S (BPS), an emerging substitute of bisphenol A, is widely used in consumer products. However, its neurodevelopmental toxicity and underlying mechanisms remain poorly understood. Using a three-stage human embryonic stem cell (hESC-H9) neural differentiation model, cells were exposed to 375\u202f\u03bcM BPS, 375\u202f\u03bcM BPS\u00a0+\u00a05\u202f\u03bcM NMDAR inhibitor (MK801), 375\u202f\u03bcM BPS\u00a0+\u00a05\u202f\u03bcM ERK pathway inhibitor (U0126), and a 0.1% DMSO solvent control, respectively. High-content screening, qPCR, and Western blot were utilized to analyze neuromorphology, intracellular Ca2+ levels, and related genes/proteins expression. Results showed that NMDAR inhibition effectively rescued BPS-induced Ca2+ dyshomeostasis and deficits in neurite complexity. Both NMDAR and ERK inhibition exacerbated apoptosis at the precursor stage but effectively reduced it at post-maturation stages. Mechanistically, BPS hyperactivates NMDAR, leading to Ca2+ influx as the primary event, which suppresses BDNF and synaptic proteins, impairing synaptogenesis and promoting apoptosis. ERK is activated downstream but independently regulates neuronal morphology rather than serving as a linear executor of NMDAR-driven toxicity. Collectively, NMDAR is the pivotal mediator of BPS neurotoxicity, and the NMDAR-ERK axis involves both convergent and divergent mechanisms, underscoring the need for stage-specific neuroprotective strategies.\n\nID: 42480468\nTitle: Synergistic vacuum steam pulse blanching and gliding arc cold plasma pretreatment enhances drying efficiency and folate retention in Yardlong bean pods.\nAbstract: Yardlong bean (Vigna unguiculata subsp. sesquipedalis) pods are rich in folate and bioactive compounds but suffer quality deterioration during hot-air impingement drying. This study evaluated vacuum steam pulse blanching (VSPB), gliding arc cold plasma (CP; 30-120\u00a0s), hot water blanching, and sequential VSPB-assisted CP (B-CP) pretreatments for improving drying efficiency and quality retention. Among combined treatments, VSPB followed by 30\u00a0s CP exposure (B-CP30) was optimal because it significantly accelerated moisture removal while maintaining structural integrity and high folate retention (p\u00a0<\u00a00.05). B-CP30 enhanced surface porosity, reduced contact angle, improved membrane permeability, and promoted uniform moisture redistribution, thereby reducing drying resistance and shortening drying time compared with untreated samples (p\u00a0<\u00a00.05). Longer plasma exposures caused excessive structural and oxidative damage. Pretreatment significantly affected shrinkage, rehydration ratio, folate, total phenolics, and flavonoids after drying (p\u00a0<\u00a00.05). Short-duration B-CP is therefore promising for high-quality dried yardlong bean pods.\n\nID: 42480069\nTitle: Novel antioxidant effects of deuterated polyunsaturated fatty acids against lipid peroxidation in cell membranes: hypothesis paper.\nAbstract: Lipid peroxidation (LPO) has long been implicated in the pathogenesis of various diseases and the role of antioxidants against LPO has been studied extensively. Recently, novel antioxidant functions of deuterated polyunsaturated fatty acids (D-PUFAs) in preventing LPO in the membranes and in humans have been reported by many research groups. The preventive and therapeutic potential of D-PUFAs against LPO and related diseases has received considerable attention, but the underlying molecular mechanisms and dynamics remain elusive. This hypothesis article summarizes state of the art preventive effects of D-PUFAs against LPO and cell damage reported in the literature and discusses the plausible mechanisms of action with an emphasis on the effects of membrane properties. Interestingly, it was found that cholesterol and oleic acid as well as D-PUFAs did not inhibit LPO in homogeneous solution, but they all suppressed LPO in the liposomal membranes, cell membranes, and partially in vivo. It is speculated that D-PUFAs suppress LPO in the membranes, at least in part, by physically obstructing the reaction between lipid peroxyl radicals and phospholipid substrates as well as by chemical and biochemical mechanisms. However, the proposed mechanism remains a hypothesis which should be validated directly in future experimental studies. D-PUFAs which have high affinity for phospholipids suppress lipid peroxidation (LPO) in the membranes, but not in solution.The preventive effects of D-PUFAs against LPO and oxidative damage were observed consistently in experimental animals.The preventive effects of D-PUFAs against oxidative damage were partially observed in human clinical studies.D-PUFAs suppress LPO in the membranes not by scavenging radicals but by physically obstructing interactions between radicals and phospholipids.\n\nID: 42478934\nTitle: Deciphering the Formulation-Dependent Neurotoxicity of Irinotecan: An Integrated Pharmacovigilance and Mechanistic Study.\nAbstract: Irinotecan is a key chemotherapeutic agent, but its neurotoxicity limits its utility. Observed differences in neurotoxicity between conventional and liposomal formulations are poorly characterized mechanistically. This study aimed to systematically compare their neurotoxicity profiles and investigate the underlying mechanisms, testing the hypothesis that the parent drug irinotecan contributes directly to neurotoxicity. We employed a multi-dimensional strategy. Computational toxicology predicted neurotoxicity for irinotecan and its metabolite SN-38. Disproportionality analysis of the FDA Adverse Event Reporting System (FAERS) compared real-world neurotoxicity signals. Network pharmacology and molecular docking explored irinotecan's direct molecular targets and pathways. Multi-platform computational prediction confirmed high neurotoxicity risk for both irinotecan and SN-38. FAERS analysis revealed a distinct clinical profile: conventional irinotecan (C-Irinotecan) was associated with both central (CNS) and peripheral nervous system (PNS) adverse events, whereas liposomal irinotecan (L-Irinotecan) signals were confined to the periphery. This CNS-specific disparity, combined with pharmacokinetic evidence, implicated the parent drug. Network analysis identified eight core neural targets (e.g., AKT1, EGFR) with high binding affinity to irinotecan. Pathway enrichment highlighted the MAPK/p38 cascade as a central mechanism. This integrated analysis demonstrates a formulation-dependent neurotoxicity dichotomy for irinotecan. We propose and provide converging evidence for a novel paradigm: prototype irinotecan is a direct mediator of neurotoxicity, and its CNS access dictates central effects. These findings offer critical insights for formulation safety and neuroprotective strategies.\n\nID: 42478584\nTitle: Hydrogel-encapsulated nanoenzymes with pH-responsive multienzyme activity for residual tumor clearance.\nAbstract: Brain gliomas, marked by their invasive nature, proximity to vital brain areas, and diffuse growth patterns, make their complete surgical resection quite challenging. To address this, we developed a hydrogel nanocomposite (MCAG-Gel) tailored for postoperative glioma treatment, which is constructed by gel loading manganese-doped hollow cerium oxide nanoparticles (MnOx/CeOx, MC NPs) and the chemotherapeutic drug axitinib (AG). MCAG-Gel adheres to the post-surgery wound and is responsive to the weakly acidic tumor microenvironment (TME), releasing MC NPs and AG for chemotherapy. Interestingly, MC NPs exhibit peroxidase-like (POD) activity and catalase-like (CAT) activity in the TME, generating reactive oxygen species (ROS) to inhibit residual glioma cells while depleting glutathione to amplify oxidative stress and alleviate tumor hypoxia. Conversely, under physiological conditions, MC NPs exhibit CAT-like and superoxide dismutase (SOD)-like activities, scavenging ROS to protect normal tissues from oxidative damage. MCAG-Gel shows good biosafety and potent anti-tumor efficacy against postoperative residual tumors in a subcutaneously implanted glioblastoma model. Collectively, these findings highlight the potential of MCAG-Gel as a promising therapeutic strategy for clinical postoperative glioma treatment.\n\nID: 42478350\nTitle: Salinity and Phenol-Induced VBNC State of Quorum-Quenching Bacterium and Its Resuscitation Strategies for Biofilm Control in Industrial Wastewater Treatment.\nAbstract: Quorum quenching (QQ) is an effective biological strategy for mitigating membrane biofouling in membrane bioreactors (MBRs), yet the persistence of QQ bacteria under harsh industrial wastewater conditions remains poorly understood. Here, the induction, resuscitation and functional recovery of the viable but nonculturable (VBNC) state in the efficient QQ bacterium Brucella sp. ZJ1 was investigated under salinity and combined phenol-salinity stress. Combined stress markedly accelerated VBNC formation (36\u2009h vs. 10\u2009days under salinity alone) and caused greater oxidative damage, metabolic suppression, structural deterioration and loss of QQ activity. Salinity-induced VBNC cells recovered following stress removal, whereas phenol-salinity-induced cells required resuscitation-promoting factor (Rpf) for efficient revival. Rpf-mediated resuscitation substantially restored both QQ activity and biofilm inhibition capacity. Transcriptomic analysis revealed that VBNC formation was accompanied by coordinated repression of genes involved in central metabolism, DNA replication and protein biosynthesis, together with activation of osmotic adaptation, membrane transport, quorum sensing and oxidative stress response pathways. These findings demonstrate that the VBNC state is an active adaptive strategy that preserves the potential for functional recovery and provides new insights for improving the antifouling performance of QQ-based MBR systems treating high-strength industrial wastewater.\n\nID: 42492072\nTitle: Examining Mgat5 upregulation's protective effects and underlying mechanisms in spinal cord injury.\nAbstract: Secondary inflammation severely hinders recovery after spinal cord injury (SCI). This study investigates whether boosting Mgat5-mediated N-glycosylation via a lentiviral vector can reprogram the local immune microenvironment and foster functional repair. We engineered a lentiviral vector to overexpress Mgat5 (Lv-Mgat5) and validated it in rat dorsal root ganglion cells. Next, we established a contusion SCI model in rats, dividing them into sham, SCI, MP (methylprednisolone), Lv-vector, and Lv-Mgat5 groups. Motor recovery was evaluated using BBB and inclined plane tests. To uncover the mechanisms, we quantified N-glycan branching (PHA-L precipitation), inflammatory cytokines (ELISA), and regeneration markers (Western blot). Lv-Mgat5 effectively upregulated \u03b2-1,6-GlcNAc branching both in vitro and in vivo without cytotoxicity. Importantly, this targeted intervention modulated the injured spinal cord microenvironment toward an anti-inflammatory profile. We observed a significant drop in TNF-\u03b1 and IL-1\u03b2, alongside a surge in IL-10 (p\u2009<\u20090.05). Furthermore, GAP-43 expression remained robustly elevated. Consequently, rats treated with Lv-Mgat5 showed remarkable and sustained improvements in hindlimb motor function compared to vehicle controls (p\u2009<\u20090.01). Targeted Mgat5 upregulation effectively modulates the post-injury microenvironment. By reshaping the N-glycosylation profile, it attenuates secondary neuroinflammation and supports a regeneration-associated molecular response, offering a promising target for gene therapy after SCI.\n\nID: 42491970\nTitle: Discovery of novel indazole derivatives with anti-neuroinflammatory activity.\nAbstract: This study focuses on the critical role of microglia-mediated neuroinflammation in various neurological disorders. Utilizing the indazole heterocycle-a scaffold known for its structural plasticity and multi-target potential-as the core structure, a series of derivatives were designed and synthesized with the aim of screening and elucidating their anti-inflammatory activity and underlying mechanisms. The activities of the compounds were systematically evaluated in an in vitro LPS-stimulated BV-2 microglial model using Griess assay, MTT assay, qPCR, and western blotting. Among the 15 derivatives obtained, compound 5o exhibited the most potent anti-inflammatory activity (IC50 = 8.45 \u00b1 0.64 \u03bcM). Its mechanism of action involves the regulation of microglial polarization-significantly suppressing M1 phenotype markers such as NO, IL-1\u03b2, IL-6, TNF-\u03b1, iNOS, and COX-2. Further mechanistic studies revealed that this effect is mediated through positive regulation nuclear translocation of Nrf2. In summary, this study demonstrates that the indazole derivative 5o exerts anti-neuroinflammatory effects by inhibiting microglial M1 polarization, providing a promising lead compound and a robust pharmacological basis for the development of novel therapeutic strategies targeting neuroinflammatory diseases.\n\nID: 42491221\nTitle: Acupuncture-induced HSP70 upregulation in neuroprotection: mitochondrial and anti-apoptotic mechanisms.\nAbstract: Heat shock protein 70 (HSP70) represents a major stress-inducible chaperone, holding considerable significance in regulating the proteostasis, mitochondrial homeostasis, and apoptosis in the injured nervous system. Acupuncture has shown neuroprotective effects in multiple models of neurological diseases, yet the role of HSP70 as a mechanistic link between acupuncture stimulation and neuronal protection has not been systematically clarified. To this end, current evidence on acupuncture-induced HSP70 regulation is hereby summarized, and its potential contribution to neuroprotection is accordingly discussed, with particular emphasis on mitochondrial preservation and anti-apoptotic signaling. Available studies suggest that acupuncture-associated HSP70 upregulation is linked to enhanced cellular stress adaptation, reduced oxidative injury, stabilization of Bcl-2 family-dependent mitochondrial integrity, inhibition of cytochrome c release and apoptosome formation, and suppression of downstream caspase activation. In addition to these intracellular effects, emerging evidence also uncovers the involvement of HSP70 in neuroinflammatory regulation and neuron-glia communication, suggesting its broader role in shaping the injured neural microenvironment. However, current evidence remains largely associative, leaving several key issues unresolved, including questions of causal necessity, cell-specific regulation, intercellular trafficking, and neuroimmune integration. Overall, HSP70 may represent a promising integrative mediator of acupuncture-induced neuroprotection, yet its precise mechanistic function still warrants further experimental validation.\n\nID: 42491134\nTitle: Epitranscriptomic regulation by m6A in immunity and autoimmune disorders: emerging mechanisms and clinical perspectives.\nAbstract: Immune-mediated diseases arise from intricate interactions among genetic, environmental, and epigenetic factors that disrupt immune homeostasis. In recent years, epigenetic mechanisms have been widely explored as critical factors in autoreactivity. Among these modifications, N6-methyladenosine (m6A) RNA methylation stands out as a pivotal post-transcriptional regulator of immune cell function and autoimmune diseases (ADs) progression. This review outlines m6A regulation in immune microenvironments and its dual role in maintaining tolerance and promoting inflammation. This study highlights how m6A regulators, including writers (METTL3/14), erasers (FTO and ALKBH5), and readers (YTHDF1-3 and IGF2BP3), orchestrate immune cell dysfunction across systemic (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriasis) and organ-specific (multiple sclerosis (MS), inflammatory bowel disease (IBD), type 1 diabetes mellitus (T1DM), and autoimmune thyroid disease (AITD) ADs, revealing disease-specific epitranscriptomic regulatory patterns. Critically, we highlight recent therapeutic breakthroughs targeting m6A regulators, including METTL3 inhibition (STM2457) for Th17-driven MS and RA synovitis, ALKBH5 modulation (ALK-04) to mitigate psoriasis flares and neuroinflammation, FTO-targeting small molecules (Rhein) to prevent RA-associated bone erosion, and IGF2BP3 blockade (triptolide) to suppress RA fibroblast activity. Despite their promise, key challenges persist, including stage-specific effects (early vs. chronic), rare immune subset targeting (MDSCs in AIH), and concerns about the long-term safety of epitranscriptomic drugs. Future studies must address m6A dynamics in immune crosstalk to advance precision medicine strategies, particularly through combinatorial approaches with existing JAK inhibitors or checkpoint modulators.\n\nID: 42490925\nTitle: Sensory signaling mediates the systemic metabolic and neurological effects of epigallocatechin gallate.\nAbstract: Epigallocatechin gallate (EGCG), the primary green tea flavanol, is renowned for its diverse health benefits; however, its low systemic bioavailability presents a long-standing paradox in nutritional science. We hypothesized that EGCG exerts its physiological effects via oral chemosensory signaling pathways, independent of intestinal absorption. This study utilized wild-type and Skn-1a-/- mice (lacking bitter taste signaling) to evaluate acute metabolic responses. Furthermore, a chronic study using high-fat/high-sucrose diet (HFSD)-fed rats was conducted to investigate the long-term effects of EGCG on systemic metabolism, neuroinflammation, and adipose and skeletal muscle morphology. Acute oral administration of EGCG or the bitter tastant denatonium benzoate significantly attenuated glycemic excursions and elevated plasma glucagon-like peptide-1 (GLP-1) levels in wild-type mice. Crucially, these effects were completely abolished in Skn-1a-/- mice, identifying bitter taste receptors as essential mediators. In the chronic rat model, repeated oral EGCG treatment effectively reduced food intake, body weight gain, and adiposity. Beyond metabolic regulation, EGCG suppressed Iba-1 expression in the hippocampal dentate gyrus, indicating an anti-neuroinflammatory effect. Notably, EGCG increased the cross-sectional area of both the soleus and extensor digitorum longus muscles across all diet groups, mimicking the beneficial effects of physical exercise. These findings indicate that EGCG acts as a \"metabolic trigger\" through Skn-1a-dependent chemosensory pathways, primarily involving T2R signaling. By demonstrating that bitter-related chemosensory signaling regulates systemic homeostasis and provides neuroprotective effects, this study supports a new concept of \"sensory nutrition.\" This research positions gastrointestinal and oral chemosensors as a novel and non-invasive therapeutic target for managing metabolic syndrome and cognitive decline, overcoming the limitations of systemic bioavailability.\n\nID: 42490858\nTitle: Microbial metabolites at the nexus of gut-brain communication and neurodevelopmental disorders.\nAbstract: The microbiota-gut-brain axis (MGBA) has emerged as a critical regulator of neurodevelopment, with microbial metabolites serving as key signaling molecules that bridge the intestinal ecosystem and the central nervous system. This review gathers current evidence that connects disruptions in microbial metabolites to the pathogenesis of neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). Our comprehensive overview discusses major neuroactive metabolite classes-short-chain fatty acids (SCFAs), tryptophan derivatives, bile acids, and phenolic compounds-and their established roles functions in affecting neuroinflammation, epigenetic programming, synaptic function, and blood-brain barrier integrity. Converging evidence from human multi-omics studies and preclinical models frequently reported patterns of metabolic dysregulation in NDDs, including reduced SCFA production, altered kynurenine pathway metabolites, and accumulation of neurotoxic compounds such as para-cresol (p-cresol). However, substantial heterogeneity exists across studies, and causal evidence in humans remains predominantly associative. We further examine the critical early-life window during which the metabolite-producing microbiome is shaped by maternal factors, nutrition, and environmental exposures, with lasting consequences for neurodevelopmental trajectories. Finally, we discuss new intervention strategies such as probiotics, dietary substrates, fecal microbiota transplantation, and metabolite-based therapies, and propose a plan to transition from associative findings to causal, personalized approaches using microbial metabolites as biomarkers and therapeutic targets in child neurodevelopment.\n\nID: 42490679\nTitle: Platelet membrane biomimetic nanoparticle-based targeted delivery system of simvastatin for the treatment of ischemic stroke.\nAbstract: Blood-brain barrier (BBB) disruption and excessive neuroinflammation are pivotal drivers of cerebral ischemia-reperfusion injury. Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke.\n\nID: 42490144\nTitle: Progressive hypothalamic neuroinflammation in ovariectomized mice parallels aging-related transcriptomic changes in the female human hypothalamus.\nAbstract: The hypothalamic changes that occur after the loss of ovarian estrogen remain poorly characterized. Here, we performed a comprehensive temporal characterization of the mouse hypothalamus following ovariectomy (OVX), combining physiological measurements with bulk RNA-sequencing of the posterior hypothalamus (PH) and preoptic area (POA) at short-term (14 days) and long-term (4 months) post-OVX. Serum LH levels rose progressively and then declined, while core temperature peaked early and subsequently normalized, recapitulating the endocrine and thermoregulatory dynamics of reproductive aging in humans. Transcriptomic analysis revealed time-dependent activation of inflammatory pathways, glial markers, and KNDy neuron-related gene networks, with the most pronounced changes emerging at 4 months post-OVX, particularly in the PH. Immunofluorescence confirmed increased NKB release, declining KNDy neuronal activity, and heightened astrocytic reactivity in the arcuate nucleus after prolonged estrogen withdrawal. To contextualize these findings, we analyzed publicly available human hypothalamic RNA-seq data across chronological age. Age-related transcriptomic patterns in women, including progressive inflammatory signaling, glial activation, and altered KNDy gene expression, showed significant correlation with the OVX mouse model, particularly at the pathway level. These findings establish a temporal framework for hypothalamic molecular changes after estrogen withdrawal, identify conserved neuroinflammatory signatures across species, and provide a preclinical platform for testing interventions targeting menopausal-associated hypothalamic dysfunction.\n\nID: 42489872\nTitle: Mesenchymal Stem Cell-Based Therapy for Cerebellar Ataxia: From Bench to Bedside.\nAbstract: Cerebellar ataxia (CA) encompasses hereditary and acquired disorders unified by Purkinje cell loss and neuroinflammation, for which no disease-modifying therapy exists. Human mesenchymal stem cells (hMSCs) offer multimodal neuroprotection through paracrine secretion of neurotrophic factors and immunomodulatory mediators. We reviewed preclinical and clinical evidence for hMSC therapy across multiple CA etiologies, integrating findings from neuroinflammatory, toxic/developmental, and genetic mouse models alongside published clinical trials and case reports. A systematic literature search was conducted in PubMed/MEDLINE, Embase, and the Cochrane Library (search period: 2000-2026) using the following key terms: \"mesenchymal stem cell\" AND \"cerebellar ataxia\"; \"MSC\" AND \"spinocerebellar ataxia\"; \"hMSC\" AND \"Purkinje cell\"; \"stem cell therapy\" AND \"ataxia\". Inclusion criteria encompassed: peer-reviewed original research articles and reviews in English; in\u00a0vivo animal model studies; clinical trials, case series, and case reports. Studies addressing non-CA neurological conditions without CA-relevant data were excluded. hMSC transplantation consistently improved motor function, preserved Purkinje cell integrity, and attenuated neuroinflammation across LPS-induced, Ara-C-induced, and SCA2 transgenic models. A critical observation is that MSCs from CA patients exhibit markedly reduced anti-inflammatory secretome capacity compared with healthy-donor MSCs, justifying an allogeneic strategy. Therapeutic efficacy was maintained even after symptom onset in the SCA2 model. A published case report demonstrated safety and preliminary functional benefit of intrathecal allogeneic bone marrow-derived MSCs in a sporadic adult-onset ataxia patient. hMSC therapy targets convergent CA pathomechanisms-microglial suppression, neurotrophin restoration, and Purkinje cell preservation-through a paracrine rather than cell-replacement mechanism. Post-symptomatic efficacy and an emerging clinical evidence base support advancing toward placebo-controlled randomized trials.\n\nID: 42489789\nTitle: Therapeutic and research frontiers in fibromyalgia: integrating pathophysiology with innovative drug repurposing.\nAbstract: Fibromyalgia (FM) is a complex chronic pain syndrome characterized by widespread musculoskeletal pain, fatigue, sleep disturbance, psychological symptoms, and cognitive dysfunction, profoundly impairing quality of life. Despite its multifactorial nature, only a few pharmacological therapies have been approved by the Food and Drug Administration (FDA), and these mainly provide symptomatic relief. Many patients experience inadequate efficacy or intolerable adverse effects, emphasizing the need for further research and improved therapeutic strategies. This review highlights contributing factors in the pathophysiology of FM, including neurochemical alterations, central sensitization, neuroinflammation, oxidative stress, mitochondrial dysfunction, gut microbiota disturbances, and autoimmunity. While some of these factors are well-established, others remain under investigation. Therapeutic strategies are discussed alongside repurposed drugs in preclinical and clinical studies, including N-methyl-D-aspartate (NMDA) receptor antagonists, neurokinin-1 receptor antagonists, drugs targeting the gamma-aminobutyric acid (GABA) system, antiepileptics, antidepressants, opioids, cannabinoids, dopamine receptor agonists, melatonin receptor agonists, and antidiabetics. Future research frontiers in FM should focus on addressing comorbidities and targeting central sensitization by enhancing descending inhibitory pain pathways, suppressing neuroinflammation through NOD-like receptor protein 3 (NLRP3) inflammasome inhibition and promotion of anti-inflammatory glial polarization besides attenuating oxidative stress and mitochondrial dysfunction. Moreover, repurposing drugs from related pain conditions such as migraine and neuropathic pain offers new therapeutic opportunities. Accordingly, this multi-target strategy may facilitate the development of effective therapies for FM.\n\nID: 42489766\nTitle: Pentoxifylline targets TLR4/MyD88/NF-\u03baB signaling to ameliorate neuroinflammation and metabolic dysfunction in a rat model of chronic hypoperfusion-induced vascular cognitive impairment.\nAbstract: Vascular cognitive impairment (VCI) driven by chronic cerebral hypoperfusion lacks disease-modifying therapy. We tested whether pentoxifylline (PTX), a methylxanthine phosphodiesterase inhibitor with dual hemorheological and anti-inflammatory properties, attenuates VCI-like cognitive and inflammatory abnormalities in a rat model. Three-month-old male Sprague-Dawley rats underwent bilateral common carotid artery occlusion (BCCAO) or sham surgery. PTX (60\u00a0mg\u00a0kg\u207b1\u00a0day\u207b1, gavage) or vehicle was administered for 28\u00a0days starting 24\u00a0h post-operation. Spatial cognition was assessed with the Morris water maze; neuronal injury, microglial activation, and glucose metabolism were evaluated by histology, immunofluorescence, 1\u2078F-FDG PET/CT, and western blotting. Systemic and hippocampal cytokines were quantified by multiplex immunoassay; TLR4/MyD88/NF-\u03baB signaling was profiled by RNA-seq and western blotting. BCCAO induced progressive cognitive deficits without sustained weight loss, paralleled by CA1 neuronal damage, microglial proliferation, and marked elevations of IL-1\u03b2, IL-2, IL-17, and TNF-\u03b1 in plasma and hippocampus. PTX shortened escape latency, restored probe-trial platform crossings, preserved neuronal morphology, suppressed microglial Iba-1\u207a/Ki67\u207a expansion, and reduced all four cytokines. Mechanistically, PTX down-regulated TLR4, MyD88, and NF-\u03baB p65 mRNA and protein, reduced nuclear translocation of NF-\u03baB p65, and partially reversed frontal and hippocampal glucose hypometabolism. Peripheral IL-1\u03b2 and IL-17 levels correlated positively with cognitive impairment. Pentoxifylline concurrently mitigates hypoperfusion-associated neuroinflammation, neuronal injury, and glucose hypometabolism via inhibition of the TLR4/MyD88/NF-\u03baB axis, supporting PTX as a readily translatable candidate for early VCI intervention.\n\nID: 42489599\nTitle: Molecular Inflammatory Characteristics of Patients With Chronic Pain Under Burst Spinal Cord Stimulation: An Exploratory Study.\nAbstract: Spinal cord stimulation (SCS) has been reported to reduce chronic back and leg pain and improve functional capacity. However, its mechanism of action is not completely understood. One proposed mechanism involves the modulation of central and peripheral inflammatory circuits. This exploratory study enrolled 28 participants (11 healthy controls [HC] and 17 patients with chronic back and/or leg pain of various origin). Pain intensity (Numeric Rating Scale), sleep quality (Pittsburgh Sleep Quality Index), mood (Beck Depression Inventory), disability (Oswestry Disability Index), and levels of pro- and anti-inflammatory cytokines (adiponectin, ghrelin, interleukin [IL]-10, high-mobility group box 1-protein, tumor necrosis factor alpha, IL-6, IL-1\u03b2, leptin) were collected at baseline and after three months of burst SCS and compared with HC. A total of 11 men and six women (mean age 68.4 \u00b1 11.2 years) underwent permanent SCS implantation. Pain intensity significantly decreased at follow-up (p < 0.001), accompanied by improvements in sleep quality (p = 0.002), mood (p = 0.001), and disability (p < 0.001). At baseline, proinflammatory tumor necrosis factor alpha levels were significantly elevated (p = 0.006), whereas anti-inflammatory IL-10 levels were significantly reduced compared with HC (p = 0.004). At follow-up, IL-10 levels increased, attenuating the difference between patients and HC such that no statistical significance was observed. Levels of pro- and anti-inflammatory cytokines showed no significant correlations with clinical outcome measures. Consistent with previously published data, we found a proinflammatory profile in patients with chronic pain at baseline. After three months of burst SCS anti-inflammatory IL-10 was increased along with improved pain and functional capacity. However, a causal relationship between burst SCS and neuroinflammatory mediators in chronic back and/or leg pain could not be established.\n\nID: 42489531\nTitle: Biochemical modulators of synaptic plasticity: New horizons in Alzheimer's disease treatment.\nAbstract: Synaptic dysfunction is the earliest and most critical pathological feature of Alzheimer's disease (AD), directly contributing to cognitive decline. This review provides an integrative overview of the molecular and biochemical modulators governing synaptic plasticity and their disruption in AD. We discuss how the collective impairment of A\u03b2 aggregation, tau pathology, calcium imbalance, oxidative stress, and neuroinflammation affects dendritic spine morphology and synaptic connectivity. Particular attention is given to neurotrophins such as brain-derived neurotrophic factor and TrkB signaling, hormonal influences, likewise glucocorticoids, estrogens, testosterone, endocannabinoid pathways, lipid and cholesterol regulators like ApoE and lipid rafts, and epigenetic mechanisms that modulate synaptic resilience. We further evaluate the therapeutic potential of pharmacological agents, including cholinesterase inhibitors, NMDA receptor modulators, and multi-target directed ligands alongside nutraceuticals such as resveratrol, curcumin, omega-3 fatty acids, Withania somnifera, and Bacopa monnieri. Emerging technologies, including iPSC-derived neuronal models, optogenetics, and advanced neuroimaging biomarkers like SV2A PET, cerebrospinal fluid/plasma neurogranin, are also highlighted for their role in elucidating and monitoring synaptic integrity. Ultimately, targeting the biochemical modulators of synaptic plasticity offers a promising avenue for AD therapy, especially through combinatorial and precision-medicine strategies aimed at restoring synaptic function and cognitive performance.\n\nID: 42489248\nTitle: Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke-Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling.\nAbstract: Ischemic stroke induces oxidative stress, neuroinflammation, neuronal death, and synaptic dysfunction, leading to persistent motor and cognitive deficits. The human dental pulp stem cell (hDPSC) secretome is a promising cell-free therapeutic candidate containing neurotrophic, antioxidant, and immunomodulatory factors. Here, we investigated its therapeutic effects in a photothrombotic mouse model of ischemic stroke and CoCl2-induced hypoxic BV2 microglial cells. Proteomic profiling identified antioxidant-associated proteins, including SOD2, GSR, and GSTP1, and microglial phenotype-related candidates, including GRN, CSF1, and LRP1. hDPSC secretome treatment reduced stroke-induced infarct volume and attenuated stroke-increased neuronal apoptosis, neuronal ROS accumulation, and NF-\u03baB-associated inflammatory signaling in the cortex and hippocampus. It also shifted microglial marker expression toward an M2-associated profile and improved stroke-impaired hippocampal neurogenesis, vascular remodeling, and synaptic organization. Proteomic analyses further identified coordinated changes in pathways related to oxidative phosphorylation, inflammatory responses, calcium signaling, SNARE-associated vesicular transport, and ROBO-Rho-associated cytoskeletal remodeling. These molecular and cellular changes were associated with improved motor coordination, spatial learning and memory, contextual memory, and anxiety-like behavior. These findings support the hDPSC secretome as a cell-free therapeutic candidate for post-stroke functional recovery linked to redox, inflammatory, neurovascular, and synaptic remodeling.\n\nID: 42489215\nTitle: Prolonged systemic inflammation worsens impairments to astrocyte Ca2+ and functional hyperemia in Alzheimer's disease.\nAbstract: Chronic neuroinflammation in Alzheimer's disease (AD) alters astrocyte physiology and neurovascular unit function. AD patients frequently experience recurrent systemic inflammatory insults from comorbid conditions, which act as\u00a0\"secondary-hits\" believed to worsen cognitive decline. The impact of these secondary insults \u00a0on astrocyte-mediated neurovascular regulation remains unknown. We applied intravital two-photon microscopy to longitudinally investigate astrocytic Ca2 + dynamics and functional hyperemia during sensory stimulation in APP/PS1dE9 mice before and during secondary lipopolysaccharide (LPS)-induced systemic inflammation. AD mice exhibited diminished stimulation-evoked astrocytic Ca2 + activity, while functional hyperemia remained largely preserved. LPS further suppressed astrocytic Ca2 + responses and produced temporally specific vascular alterations, with AD and wild-type mice following divergent inflammatory trajectories. Our findings provide the first in vivo longitudinal characterization of how secondary systemic inflammation disrupts astrocyte-mediated neurovascular regulation. The selective vulnerability of astrocytic Ca2 + signaling relative to vascular output implicates recurrent inflammatory insults as a clinically relevant contributor to neurovascular dysfunction in preclinical AD.\n\nID: 42489128\nTitle: Photobiomodulation of immune crosstalk rescues neuroinflammation in Alzheimer's disease models.\nAbstract: Peripheral immune cell infiltration and crosstalk with brain-resident cells critically drive Alzheimer's disease (AD)-associated neuroinflammation, highlighting its therapeutic potential. Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement. Reprogramming central-peripheral immune crosstalk with PBM resolves neuroinflammation and restores cognition in AD models-a translatable strategy for combating neurodegeneration.\n\nID: 42488849\nTitle: Modulation of TH17 cell activity by REV-ERB agonists: path toward novel treatments for canine meningoencephalitis of unknown origin.\nAbstract: Meningoencephalitis of unknown origin (MUO) encompasses a heterogeneous group of non-infectious, presumed autoimmune, central nervous system diseases in dogs and remains a major therapeutic challenge in veterinary neurology. Mounting evidence from both experimental and clinical studies has highlighted the pivotal role of T helper 17 (Th17) cells and their proinflammatory cytokines, especially interleukin-17A (IL-17A), in mediating neuroinflammation similar to that seen in experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS) models. REV-ERBs are nuclear receptors that act as transcriptional repressors and regulate immune responses, circadian rhythm, and metabolism. Synthetic REV-ERB agonists, such as SR9009, SR9011, and SR12418, have demonstrated selective suppression of Th17 differentiation and function, reduction of disease severity, and improved safety profiles in preclinical autoimmune models. In addition to Th17 differentiation, REV-ERB's role in other components of the immunomodulating system is ever-growing. Preclinical and translational data support the further exploration of REV-ERB agonists as a potential addition to the targeted immunomodulatory therapies for canine MUO. By continuing to investigate REV-ERB compounds as a component of MUO therapy, researchers can assess their potential for improved efficacy and reduce the side effects associated with traditional immunosuppressive regimens. This review integrates mechanistic insights from immunology, circadian biology, and experimental models, and outlines future directions for clinical translation, highlighting the relevance of REV-ERB agonists in advancing veterinary neuroimmunology and in informing comparative approaches to human neuroautoimmune disease.\n\nID: 42488679\nTitle: Clinical and preclinical evidence of meningeal immunity and glymphatic pathways in stroke: a systematic review.\nAbstract: Glymphatic transport, meningeal lymphatic drainage, and meningeal immunity have been implicated in metabolic waste clearance, cerebral edema formation, and the regulation of neuroinflammation after stroke. However, the available evidence remains fragmented and has not been systematically integrated. This review was conducted in accordance with PRISMA guidelines. PubMed, Embase, Scopus, the Cochrane Library, and Web of Science were searched from database inception to April 3, 2026, for studies investigating glymphatic pathways, the meningeal lymphatic system, meningeal immune responses, and related imaging biomarkers in patients with clinical stroke or in experimental stroke models. Two investigators independently screened studies, extracted data, and assessed study quality. Because of substantial heterogeneity in study design, imaging methodology, experimental models, and outcome measures, findings were synthesized narratively. A total of 64 studies were included, comprising 17 clinical studies and 47 preclinical studies. Clinical studies, which were largely based on MRI-derived glymphatic imaging biomarkers, suggest that glymphatic dysfunction is associated with stroke severity, cognitive impairment, and clinical outcomes. Preclinical evidence indicates that AQP4 dysregulation, impaired meningeal lymphatic drainage, and border-associated immune activation may influence waste clearance, cerebral edema, inflammation, and tissue repair after stroke. Future studies should establish standardized imaging frameworks, conduct prospective longitudinal validation, define mechanistic differences across stroke subtypes, and facilitate the translation of targeted interventions. https://www.crd.york.ac.uk/PROSPERO/home, identifier CRD420261359988.\n\nID: 42488669\nTitle: Expanding the clinical spectrum of pediatric CASPR2 antibody-associated autoimmune encephalitis: a multicenter case series.\nAbstract: Contactin-associated protein-like 2 (CASPR2) antibody-associated autoimmune encephalitis is rare in children, and available clinical data are limited. Our aim is to describe the clinical spectrum, diagnostic findings, treatment, and outcomes of all pediatric CASPR2 antibody-associated encephalitis patients reported in Hungary. We present a retrospective case series including nine pediatric patients diagnosed with CASPR2 antibody-associated encephalitis across five centers. Clinical, laboratory, imaging, electrophysiological findings, treatment, and follow-up data were collected. The mean age at onset was 4.1 \u00b1 2.6 years. All patients were serum CASPR2 antibody-positive; two had CSF positivity. The most common symptoms included sleep disorder, irritability, aggressiveness, hypertension, tachycardia, abdominal pain, itching, exanthema, and weight loss. No specific abnormalities were detected on MRI, EEG, or laboratory testing. Immunotherapy led to favorable outcomes in nearly all patients, with one relapse during follow-up. This series expands the clinical spectrum of CASPR2-associated autoimmune encephalitis in children. The presenting symptoms in pediatric patients may differ not only from those observed in adults but also from other forms of autoimmune encephalitis. The diagnostic process is especially complex due to the variability and age-related evolution of clinical manifestations, which can be difficult to recognize in younger children and commonly contribute to diagnostic delay. Early recognition and immunotherapy are associated with favorable prognosis. This case series underscores the importance of recognizing the diverse spectrum of presenting symptoms and highlights the need for raising awareness of the clinical variability. Larger prospective studies are needed to define diagnostic, therapeutic strategies and prognostic factors in the pediatric population.\n\nID: 42488639\nTitle: Autoimmune signatures in neurodegenerative dementias: from peripheral immune activation to CNS pathology.\nAbstract: Neurodegenerative dementias, including Alzheimer's disease, Parkinson's disease dementia, dementia with Lewy bodies, and related tauopathies, are traditionally defined by protein aggregation, neuronal dysfunction, synaptic loss, and glial-mediated neuroinflammation. However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses.\n\nID: 42488574\nTitle: Developmentally sensitive neuropharmacological effects of dexamethasone in neonatal bronchopulmonary dysplasia-associated brain injury via microglial Acod1-itaconate/IL-1\u03b2 signaling.\nAbstract: Bronchopulmonary dysplasia (BPD) in preterm infants is frequently accompanied by neurodevelopmental impairment, yet the central neuropharmacological actions of dexamethasone (DEX), a commonly used therapy for severe or evolving BPD, remain incompletely understood. In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain.\n\nID: 42488571\nTitle: Immune-related mechanisms of fecal microbiota transplantation in the intestinal microenvironment as a potential intervention for autism spectrum disorder patients.\nAbstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by behavioral, cognitive, and motor impairments. There is increasing evidence linking ASD with an altered composition of the gut microbiota and chronic low-grade inflammation, suggesting a key role of the gut-brain axis (GBA) in the pathophysiological development of this condition. This mini review explores the molecular and immunological mechanisms underlying the associations between ASD and gut dysbiosis, with particular emphasis on the therapeutic potential of fecal microbiota transplantation (FMT). Dysbiosis can compromise the integrity of the intestinal barrier, increasing permeability and the translocation of pathogen-associated molecular patterns (PAMPs), such as lipopolysaccharides (LPS), thereby releasing inflammatory cytokines, including IL-6 and TNF-\u03b1. These mediators activate the mucosal immune pathways, such as the NF-\u03baB signaling and NLRP3 inflammasome, thereby contributing to neuroinflammation and elevating intestinal biomarker levels, such as S100B, RANTES, and calprotectin. Emerging evidence suggests that FMT may restore microbial diversity, promote the expansion of beneficial short-chain-fatty-acid-producing taxa, and reinforce intestinal tight junction proteins, thereby improving the integrity of the gut barrier. These effects may attenuate systemic inflammation, modulate central immune responses, regulate neurotransmitter levels, and improve gastrointestinal and behavioral outcomes in individuals with ASD. Despite these promising findings, current evidence remains limited by small sample sizes, methodological heterogeneity, and short follow-up periods. Hence, future research efforts should prioritize well-designed randomized controlled trials and the development of personalized microbial-based interventions to establish FMT as a safe and effective therapeutic strategy for ASD.\n\nID: 42488555\nTitle: Modeling Alzheimer's disease with brain organoids: mechanisms, applications, and future directions.\nAbstract: Human pluripotent stem cell-derived brain organoids have emerged as a transformative platform for modeling Alzheimer's disease (AD), thus addressing long-standing translational obstacles posed by the disease's complex etiology and interspecies differences. This review systematically examines methodological advances in brain organoid technology, from basic fabrication and brain-region-specific organoids to multicellular assembloids that incorporate microglia and vascular components, with an emphasis on strategies for overcoming fetal-like phenotypes. We surveyed literature published between 2018 and April 2026 that focused on human iPSC-derived organoid models that recapitulate core AD pathologies, including A\u03b2 plaques, tau tangles, neuroinflammation, and blood-brain barrier dysfunction. Key findings demonstrate that organoids effectively capture genotype-phenotype relationships for major AD genes (APP, PSEN1, PSEN2, and APOE\u03b54), enable the dissection of signaling pathway dysregulation (Wnt/\u03b2-catenin), and when combined with CRISPR editing and single-cell multi-omics, reveal cell-type-specific disease mechanisms. Organoids have also been successfully applied to patient-specific \"avatar\" models and high-throughput drug screening, thus advancing precision medicine approaches. However, current technological bottlenecks-including a lack of functional vascularization, batch-to-batch variability, and insufficient standardization-limit the full recapitulation of chronic, age-dependent AD pathology. This review critically evaluates these limitations, addresses ethical considerations surrounding neural organoids, and looks forward to future integration with artificial intelligence, spatial omics, and multi-organ systems to accelerate the translation of organoid-based discoveries into clinical applications.\n\nID: 42488470\nTitle: Electrochemical monitoring of early astrocytic responses underlying the synergistic effect of extracellular matrix softening and hypoxia.\nAbstract: Traumatic brain injury (TBI) disrupts central nervous system homeostasis, leading to extracellular matrix (ECM) softening and localized hypoxia and thus contributing to astrocytic activation and sustained neuroinflammation. But the interplay between ECM softening and hypoxia in regulating astrocytic activation and response remains elusive. To understand this, we developed an in vitro model incorporating tunable-stiffness hydrogels and a precise oxygen-control system to simulate the mechanical and hypoxic microenvironment of TBI. We characterized the activation-related proteins and cytokine production of astrocytes under the in vitro model, and found that soft ECM and hypoxia independently promote astrocytic activation and synergistically activate astrocytes via HIF-1\u03b1/YAP-NF-\u03baB signaling, resulting in astrocytic redox imbalance and neuroinflammation. We further used scanning electrochemical microscopy (SECM) to track the dynamic changes in glutathione (GSH) efflux and membrane integrity in live astrocytes in situ under pathophysiological conditions of ECM softening and hypoxia. The SECM results show that the combined ECM softening and hypoxia progressively impair cellular membrane integrity and promote GSH efflux of astrocytes, corresponding to the early changes in astrocytic function and indicative of an early activation-primed state to exacerbate secondary injury of astrocytes. Last, we found that the lovastatin (a neuroprotective agent) treatment can effectively attenuate astrocytic membrane impairment and decrease GSH efflux, proving the potential of lovastatin to mitigate inflammation and preserve neuroregulatory function. Our work observes the in situ and early state changes of astrocytes under a combined mechanical-hypoxic microenvironment for the first time. The findings offer mechanistic insights into TBI pathogenesis and highlight promising strategies for early therapeutic intervention.\n\nID: 42488186\nTitle: Apigenin for Depression and Anxiety: A Systematic Review of Preclinical Studies.\nAbstract: Depression and anxiety are debilitating disorders with complex pathophysiologies associated with neurotransmitter deficits, neuroinflammation, and oxidative stress. Apigenin, a dietary flavonoid, has therapeutic potential because of its neuroprotective properties. We assessed the antidepressant and anxiolytic effects of apigenin in rodent models, focusing on behavioral outcomes, mechanisms involving neuroinflammation, oxidative stress, and neurotransmitter balance, and relevant molecular pathways. A systematic search of PubMed, Scopus, and Embase was conducted through July 2025. In vivo rodent studies evaluating the effects of apigenin on depression or anxiety were included. Exclusion criteria comprised studies addressing other disorders, apigenin derivatives, or non-original research. Data on study design, model, treatment, outcomes, and mechanisms were extracted. Of 953 screened records, 21 studies met the inclusion criteria. Preclinical evidence consistently indicated that apigenin ameliorated depressive- and anxiety-like behaviors across diverse rodent models, frequently demonstrating effects comparable to or greater than those of conventional pharmacological treatments. Mechanistically, apigenin mediated its neuropsychological effects through multiple pathways, including reducing oxidative and nitrosative stress, inhibiting neuroinflammation, modulating monoaminergic neurotransmission, upregulating neurotrophic factors such as brain-derived neurotrophic factor (BDNF) and cAMP response element-binding protein (CREB), and regulating energy metabolism and neurogenesis. Apigenin exhibited a favorable safety profile across all included studies, even at high doses. In rodent models, apigenin exhibits substantial antidepressant and anxiolytic effects through complex mechanisms involving redox modulation, anti-inflammatory activity, neurotransmitter regulation, and neurotrophic support. These findings indicate that apigenin warrants further translational investigation and potential therapeutic development for treating depression and anxiety disorders.\n\nID: 42488002\nTitle: Associations of seminal plasma metal mixtures with sperm quality parameters and exploratory mediation analysis of urinary oxidative stress biomarkers: a cross-sectional study from the RHCC-AC preconception cohort.\nAbstract: There is increasing concern over the global decline in semen quality. However, the role of environmental metal exposure remains uncertain, and the underlying mechanisms are poorly understood. A cross-sectional cohort study included 425 men from the Reproductive Health of Childbearing Couples-Anhui Cohort (RHCC-AC). Seventeen metals in seminal plasma were quantified by ICP-MS. Eight urinary oxidative stress biomarkers were measured by UPLC-MS/MS. Sperm quality parameters included sperm concentration, progressive motility, total motility, abnormality rate, and sperm DNA fragmentation index (DFI). Weighted quantile sum (WQS) regression was applied to assess single and joint effects of metal mixtures. In addition, exploratory mediation analysis was conducted to examine the potential mediating role of oxidative stress in the associations between metal exposure and sperm quality. Single-metal analyses showed that Al was positively associated with sperm abnormality rate, whereas Co and Cu were inversely associated with progressive and total motility. As, Fe, and Se were positively associated with sperm concentration. In mixture analyses, Al was the primary contributor to increased sperm abnormality rate (positive-direction WQS: \u03b2\u00a0=\u00a00.014; 95% CI: 0.004-0.024; Al weight = 0.357). Co was the main contributor to reduced total motility (\u03b2 = -0.188; 95% CI: -0.309 to -0.067; Co weight = 0.419). Few significant associations were observed between metals and oxidative stress biomarkers. Among oxidative stress markers, dityrosine(diY) was positively associated with sperm abnormality rate, while D,L-ortho-tyrosine(D,L-o-tyrosine) was negatively associated with sperm concentration. Exploratory mediation analysis revealed that D,L-o-tyrosine significantly mediated the associations of seminal plasma Hg and V with sperm concentration, with mediated proportions of 11.8% and 13.0%, respectively. Seminal plasma metal mixtures, particularly Al and Co, were associated with sperm quality. Exploratory mediation analysis suggested potential indirect effects of D,L-o-tyrosine in the associations of Hg and V with sperm concentration, but these findings should be interpreted cautiously. Further studies using seminal or reproductive tract-specific oxidative stress biomarkers are warranted to clarify the role of oxidative stress in linking metal exposure to male reproductive system injury.\n\nID: 42487723\nTitle: Targeting cannabinoid receptor 1 for multiple sclerosis: molecular docking and dynamic insights of berberine and curcumin as potential therapeutic agents.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system characterized by demyelination, inflammation, and progressive neurodegeneration. Cannabinoid receptor 1 (CB1) plays a role in neuroprotection and modulation of inflammatory responses, making it a potential therapeutic target in MS. This study evaluated selected natural compounds as CB1 modulators using an integrated computational approach. Compounds were screened based on ADMET properties, followed by molecular docking and 100 ns molecular dynamics simulations. Berberine and curcumin demonstrated binding affinities of -7.9 kcal/mol and -9.4 kcal/mol, respectively. Key binding interactions involved residues VAL137, LEU404, PHE408, ARG405, and ARG409 for berberine, and MET363, LEU193, LEU359, TRP356, PHE189, PHE177, HIS178, PHE174, PHE379, ALA380, and SER383 for curcumin. Stability analyzes including RMSD, RMSF, secondary structure elements, and protein-ligand contacts, indicated stable complex formation. These findings suggest that berberine and curcumin may serve as potential lead candidates targeting CB1 and warrant further experimental validation in multiple sclerosis research.\n\nID: 42487693\nTitle: Microglial Sestrin2 alleviates depressive-like behaviors and cognitive impairment in a YTHDF1-dependent manner.\nAbstract: This study aims to investigate the role of microglial Sestrin2 in chronic unpredictable stress (CUS)-induced depressive-like behaviors and cognitive impairment in mice, and to explore the upstream molecular mechanism underlying the abnormal expression of microglial Sestrin2. Microglia-specific overexpression of Sestrin2 was achieved by injecting adeno-associated virus (AAV) into the CUS mouse hippocampus. Depressive-like behaviors were assessed using sucrose preference, tail suspension, and forced swim tests. Cognitive function was evaluated by the Morris water maze. Levels of IL-1\u03b2 and IL-6 in the hippocampus and cell supernatants were measured by ELISA. BV2 microglial cells were used for in vitro mechanistic studies. YTHDF1 siRNA and overexpressive lentivirus were used to regulate YTHDF1 expression in vitro. RNA immunoprecipitation was performed to demonstrate the physical interaction between YTHDF1 and Sestrin2 mRNA. Sestrin2 expression was significantly reduced in the hippocampus of CUS mice. Overexpression of Sestrin2 specifically in microglia ameliorated CUS-induced depressive-like behaviors, cognitive impairment, and inflammatory levels. YTHDF1 expression was also reduced in the CUS hippocampus. Mechanistically, YTHDF1 bound to Sestrin2 mRNA and knockdown of YTHDF1 decreased Sestrin2 expression. Molecular biology prediction results showed that positions 1943 and 2,114 of Sestrin2 mRNA are high-confidence N6-methyladenosine (m6A) modification sites. Mutation of the 2,114 site on Sestrin2 mRNA inhibited the effect of YTHDF1 on 3Flag expression. Furthermore, YTHDF1 knockdown promoted IL-1\u03b2 and IL-6 production in BV2 cells, which was reversed by Sestrin2 overexpression. Microglial Sestrin2 alleviates depressive-like behaviors, cognitive impairment and neuroinflammation. YTHDF1 regulates Sestrin2 expression via an m6A-dependent mechanism, and the YTHDF1-Sestrin2 axis may represent a novel therapeutic target for major depressive disorder.\n\nID: 42487585\nTitle: Depression in Epilepsy: Drug and Non-Drug Interventions Based on Multimodal Pathogenesis.\nAbstract: Depression is a common comorbidity in patients with epilepsy, significantly impacting their quality of life. However, the precise mechanisms underlying depression in epilepsy remain unclear. This review synthesizes the latest research on the pathogenesis of depression in epilepsy, focusing on abnormalities in monoamine neurotransmitters, neuroinflammation, HypothalamicPituitary-Adrenal (HPA) axis dysfunction, neurotrophic factors, mitochondrial dysfunction, and oxidative stress. The article explores the dual roles of antidepressants and antiepileptic drugs (AEDs) in the treatment of depression in epilepsy, highlighting drugs that may exacerbate either depression or seizure activity. The need for more nuanced treatment strategies, including the careful selection of antidepressants and AEDs, is emphasized. Additionally, non-drug interventions, such as Cognitive-Behavioral Therapy (CBT), neuromodulation techniques, and dietary modifications (anti-inflammatory and antioxidant foods), are reviewed as vital adjuncts to pharmacological treatments. This article aims to guide clinicians in choosing optimal treatment strategies and underscores the importance of timely depression screening, long-term management, and personalized therapy for patients with epilepsy and comorbid depression.\n\nID: 42486997\nTitle: Peripheral blood inflammatory biomarkers and response to vagus nerve stimulation in pediatric drug-resistant epilepsy: A retrospective cohort study.\nAbstract: Vagus Nerve Stimulation (VNS) is an established treatment for drug-resistant epilepsy (DRE) in children, but response rates vary significantly (50%-60%). Given that neuroinflammation is implicated in epilepsy and VNS may modulate systemic inflammation, this study explored associative links between routine blood inflammatory indices and VNS treatment response in pediatric DRE. We retrospectively analyzed 108 pediatric DRE patients who received VNS. Six peripheral inflammatory indices, namely neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammatory response index (SIRI), and pan-immune-inflammation value (PIV), were calculated at preoperative and post-titration 12\u00a0months. We used Multivariable Regression and Latent Change Score Models (LCSM) to assess the impact of baseline status and dynamic postoperative changes. Multivariable analyses revealed associations between inflammatory indices and VNS outcomes. The LCSM demonstrated that the associative roles of these indices were temporally distinct: VNS response showed significant correlations with the magnitude of postoperative change in Lymphocyte count (beta\u2009=\u2009\u2009-\u20090.73, p\u2009<\u20090.01), NLR (beta\u2009=\u20090.69, p\u2009<\u20090.01), and SIRI (beta\u2009=\u20090.75, p\u2009<\u20090.01), independent of baseline status. Conversely, the associative patterns of PIV and SII were primarily related to their initial baseline levels. \u00a0The efficacy of VNS in pediatric DRE is associated with systemic inflammatory dynamics. Postoperative changes in these inflammatory indices are associated with VNS treatment outcomes and may serve as a potential prognostic indicator for clinical response. \u2022 Vagus nerve stimulation (VNS) is an effective therapy for pediatric drug-resistant epilepsy (DRE), yet treatment response varies markedly across individuals. \u2022 Neuroinflammation is involved in epileptogenesis, and VNS may exert antiseizure effects via modulating systemic inflammation. \u2022 Peripheral inflammatory indices are easily accessible but their associative links with VNS response remain unclear. \u2022 This study first demonstrates that preoperative and postoperative dynamic changes in peripheral inflammatory biomarkers independently associate with VNS efficacy in children. \u2022 Latent change score modeling reveals that postoperative reductions in neutrophil-to-lymphocyte ratio (NLR) and systemic inflammatory response index (SIRI) correlate with favorable seizure outcomes, while baseline systemic immune-inflammation index (SII) and pan-immune-inflammation value (PIV) levels help identify favorable candidates. \u2022 These low-cost peripheral indices display correlative links with treatment outcomes and may provide preliminary reference information for auxiliary stratification and serial follow-up monitoring.\n\nID: 42486828\nTitle: [CHIR99021 alleviates neuroinflammation in a mouse model of Parkinson's disease by inhibiting the GSK-3\u03b2/NF-\u03baB pathway].\nAbstract: To investigate the effect of CHIR99021 for improving neuroinflammation in a mouse model of Parkinson's disease (PD) and the role of the GSK-3\u03b2/NF-\u03baB pathway in mediating this effect. In the cell experiment, induced SH-SY5Y cells were pretreated with 3 \u03bcmol/L CHIR99021 for 2 h prior to MPP+ treatment. In a male C57BL/6 mouse model of MPTP-induced PD, the effect of intraperitoneal injection of CHIR99021 for 7 days on motor function of the mice were assessed using behavioral tests. Western blotting and immunofluorescence staining were used to detect the changes in the GSK-3\u03b2/NF-\u03baB pathway, NLRP3 inflammasome and autophagy in both SH-SY5Y cells and the mouse models. MPP+-treated SH-SY5Y cells showed significantly downregulated expression of p-GSK-3\u03b2 protein and upregulated expressions of p-NF-\u03baB p65, ASC, NLPR3, and caspase-1, and these changes were obviously attenuated by pretreatment with CHIR99021. Compared with normal mice, the PD mouse models showed significantly decreased motor function and reduced TH neurons in the brain with lowered expression of p-GSK-3\u03b2, increased expression of p-NF-\u03baB p65 (Ser536), and upregulated ASC, NLPR3, and caspase-1 expressions. Treatment with CHIR99021 significantly increased the expression of p-GSK-3\u03b2, and reduced the expression of p-NF\u2011\u03baB p65 (Ser536), ASC, NLPR3, and caspase-1. CHIR99021 inhibits the GSK-3\u03b2/NF\u2011\u03baB signaling pathway to improve motor function of PD mice, reduce neuroinflammation, and activate autophagy to maintain the homeostasis of intracellular environment, suggesting that targeting GSK-3\u03b2, a potential multifunctional therapeutic target, can simultaneously regulate multiple key pathological links in PD. \u76ee\u7684: \u63a2\u8ba8CHIR99021\u6291\u5236GSK-3\u03b2/NF-\u03baB\u901a\u8def\u6539\u5584\u5e15\u91d1\u68ee\u75c5\u795e\u7ecf\u708e\u75c7\u7684\u4f5c\u7528\u3002\u65b9\u6cd5: SH-SY5Y\u7ec6\u80de\u52a0\u51651-\u7532\u57fa-4-\u82ef\u57fa\u5421\u5576\uff08MPP+\uff09\uff081 mmol/L\uff09\u57f9\u517b24 h\uff0c\u6784\u5efaMPP-PD\u7ec6\u80de\u6a21\u578b\uff0c\u6cbb\u7597\u7ec4SH-SY5Y\u7ec6\u80de\u5148\u7ecfCHIR99021\uff083\u03bcmol/L\uff09\u9884\u5904\u74062 h\uff0c\u518d\u52a0\u5165MPP+\uff081 mmol/L\uff09\u57f9\u517b24 h\u3002\u5c06\u91ce\u751f\u578b\uff08WT\uff09\u5c0f\u9f20\u8fde\u7eed5 d\u8179\u8154\u6ce8\u5c041-\u7532\u57fa-4-\u82ef\u57fa-1\uff0c2\uff0c3\uff0c6-\u56db\u6c22\u5421\u5576\uff08MPTP\uff09\u6784\u5efaMPTP-PD\u52a8\u7269\u6a21\u578b\uff0c\u6cbb\u7597\u7ec4\u8fde\u7eed7 d\u8179\u8154\u6ce8\u5c04CHIR99021\uff0c\u4ece\u7b2c3\u5929\u5f00\u59cb\u95f4\u969412 h\u518d\u8179\u8154\u6ce8\u5c04MPTP\uff0c\u8fde\u7eed\u6ce8\u5c045 d\u3002\u4ee5WT\u578b\u5c0f\u9f20\u4f5c\u5bf9\u7167\uff0c\u901a\u8fc7\u65f7\u573a\u5b9e\u9a8c\u3001\u722c\u6746\u5b9e\u9a8c\u3001\u75b2\u52b3\u8f6c\u68d2\u5b9e\u9a8c\u8bc4\u4f30\u5404\u7ec4\u8fd0\u52a8\u884c\u4e3a\u80fd\u529b\u3002\u901a\u8fc7Western blotting \u548c\u514d\u75ab\u8367\u5149\u68c0\u6d4bCHIR99021\u5728\u4f53\u5185\u548c\u4f53\u5916\u6291\u5236GSK-3\u03b2/NF-\u03baB\u901a\u8def\u4fe1\u53f7\u8c03\u63a7NLRP3\u708e\u75c7\u5c0f\u4f53\u6fc0\u6d3b\u548c\u7ec6\u80de\u81ea\u566c\u6539\u5584\u5e15\u91d1\u68ee\u75c5\u795e\u7ecf\u708e\u75c7\u7684\u4f5c\u7528\u3002\u7ed3\u679c: \u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cMPP\u207a-PD\u7ec6\u80de\u6a21\u578b\u4e2d\uff0cp-GSK-3\u03b2 \uff08Ser9\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u4e0b\u8c03\uff08P<0.01\uff09\uff0c\u800c\u603bGSK-3\u03b2\u86cb\u767d\u91cf\u5dee\u5f02\u6ca1\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\u3002p-NF-\u03baB p65 \uff08Ser536\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u4e0a\u8c03\uff08P<0.01\uff09\uff0c\u800c\u603bNF-\u03baB p65 \uff08Ser536\uff09\u86cb\u767d\u91cf\u5dee\u5f02\u6ca1\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\u3002\u540c\u65f6ASC\u3001NLPR3\u3001Caspase-1\u708e\u75c7\u5c0f\u4f53\u8868\u8fbe\u4e0a\u8c03\uff08P<0.01\uff09\u3002\u800c\u5728MPP\u207a+CHIR99021\u7ec4\u4e2d\uff0cp-GSK-3\u03b2\u3001NF-\u03baB\u53ca\u708e\u75c7\u5c0f\u4f53\u86cb\u767d\u8868\u8fbe\u4e0b\u8c03.\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cMPTP-PD\u5c0f\u9f20\u6a21\u578b\u4e2d\uff0c\u5c0f\u9f20\u8fd0\u52a8\u529f\u80fd\u4e0b\u964d\uff08P<0.001\uff09\uff0c\u8111\u5185TH\u795e\u7ecf\u5143\u51cf\u5c11\uff08P<0.01\uff09\u3002\u9ed1\u8d28\u90e8\u4f4d\u7684p-GSK-3\u03b2 \uff08Ser9\uff09\u6c34\u5e73\u540c\u6837\u964d\u4f4e\uff08P<0.01\uff09\uff0c\u603bGSK-3\u03b2\u86cb\u767d\u91cf\u53d8\u5316\u5dee\u5f02\u65e0\u7edf\u8ba1\u5b66\u610f\u4e49\u3002\u800cp-NF-\u03baB p65 \uff08Ser536\uff09\u6c34\u5e73\u540c\u6837\u663e\u8457\u5347\u9ad8\uff08P<0.01\uff09\uff0c\u603bNF-\u03baB p65\u86cb\u767d\u91cf\u8868\u8fbe\u53d8\u5316\u5dee\u5f02\u65e0\u7edf\u8ba1\u5b66\u610f\u4e49\uff0cASC\u3001NLPR3\u3001Caspase-1\u708e\u75c7\u5c0f\u4f53\u8868\u8fbe\u4e0a\u8c03\uff08P<0.01\uff09\u3002\u800cMPTP-CHIR99021\u7ec4\u8f83MPTP-PD\u7ec4\u76f8\u6bd4\uff0cp-GSK-3\u03b2\u3001NF-\u03baB\u53ca\u708e\u75c7\u5c0f\u4f53\u86cb\u767d\u8868\u8fbe\u4e0b\u8c03\uff08P<0.01\uff09\u3002\u7ed3\u8bba: CHIR99021\u901a\u8fc7\u6291\u5236GSK-3\u03b2/NF-\u03baB\u4fe1\u53f7\u901a\u8def\uff0c\u663e\u8457\u6539\u5584\u5e15\u91d1\u68ee\u75c5\uff08PD\uff09\u5c0f\u9f20\u7684\u8fd0\u52a8\u529f\u80fd\uff0c\u51cf\u8f7b\u795e\u7ecf\u708e\u75c7\uff0c\u5e76\u6fc0\u6d3b\u7ec6\u80de\u81ea\u566c\u4ee5\u7ef4\u6301\u7ec6\u80de\u5185\u73af\u5883\u7a33\u6001\u3002\u9776\u5411GSK-3\u03b2\u53ef\u540c\u65f6\u8c03\u63a7PD\u591a\u4e2a\u5173\u952e\u75c5\u7406\u73af\u8282\uff0c\u5177\u6709\u4f5c\u4e3a\u591a\u529f\u80fd\u6cbb\u7597\u9776\u70b9\u7684\u6f5c\u529b\u3002.\n\nID: 42486420\nTitle: Cerebrospinal fluid N-glycans as potential biosignatures for developmental and epileptic encephalopathy in children.\nAbstract: Epilepsy is the most prevalent neurological disorder in children, significantly impacting the growth and development of future generations. Despite substantial progress in biomarker discovery, numerous challenges persist in the accurate diagnosis and prognosis of pediatric epilepsy. Glycosylation is known to play a critical role in neuronal function and neuroinflammation, but the differential glycome profile associated with the onset and progression of pediatric epilepsy has not been investigated. This study investigates the alterations in N-glycan signatures present in plasma and cerebrospinal fluid (CSF) from individuals experiencing focal and generalized epilepsy and developmental and epileptic encephalopathies (DEE). Discriminative models demonstrate distinct N-glycome profiles in both plasma and CSF that effectively differentiate between control subjects and those with epilepsy, identifying a specific set of 11 N-glycans common to both biological fluids. Notably, we observed a significant elevation in mannosylation and mono-sialylation of CSF in cases of DEE. High mannosylated and mono-sialylated N-glycans exhibited strong diagnostic potential for DEE. The biosynthetic network of CSF N-glycans indicated that sialylation, galactosylation, and bisection are the primary contributors to the transition from controls to DEE. Furthermore, the abundance of sialylation, fucosylation, and bisection correlated positively with the levels of proteins and sugars in CSF. These findings identify N-glycosylation changes in CSF as biosignatures associated with pediatric epilepsy, especially DEE, and support further evaluation of glycoprotein N-glycome profiling for disease classification and clinical stratification.\n\nID: 42486342\nTitle: Estrogen's Master Switch: NF\u03baB-NLRP3, SIRT1-HMGB1, and TLR4 Triad Tamed for Brain Rescue in Ageing and Neurodegeneration.\nAbstract: Estrogen operates as a pleiotropic steroidal, neuroendocrine modulator to combat accelerated brain ageing and neurodegeneration by addressing a convergent inflammatory-metabolic trio. Estrogen receptor-dependent neural cellular signalling reduces TLR4-mediated immune priming and NF-\u03baB activation, preventing NLRP3 inflammasome assembly and pro-inflammatory cytokine release. Concurrently, estrogen increases SIRT1 activity, restoring metabolic and epigenetic equilibrium while inhibiting HMGB1 acetylation, translocation, extracellular release, and activation of the stress-response pathway. Coordinated regulation of the TLR4-NF\u03baB-NLRP3 and SIRT1-HMGB1 molecular triad reduces chronic neuroinflammation, preserves neuronal integrity, metabolic resilience, and slows persistent inflammation-driven brain ageing. This highlights estrogen and estrogen-based steroidal modulators as promising therapeutic candidates for reversing accelerated cognitive ageing and neurodegenerative disorders. However, a crucial research gap persists in the absence of a systems-level assessment of neurosteroids as a multi-target regulator of convergent innate immunological and metabolic signalling networks. The control of the TLR4-NF\u03baB-NLRP3 inflammasome axis and the SIRT1-HMGB1 metabolic-epigenetic checkpoint has not been well studied as an interrelated, steroidal druggable trifecta driving brain homeostasis and neurodegeneration. These pathways are often studied in isolation, despite overwhelming evidence that their bidirectional interplay contributes to persistent neuroinflammation, immunometabolic dysfunction, and cellular senescence. This review synthesises evidence from molecular endocrinology, biochemical, pre-clinical, and clinical models to advance a mechanistically integrated and therapeutically actionable framework that aligns into a unified endocrine, metabolic, and immune target-driven framework relevant to complex, inflammation-driven brain ageing, thereby offering a strong foundation and paving the way for future molecular target validation and disease-modifying, steroid-mimetic interventions against neurodegeneration.\n\nID: 42486320\nTitle: Repressor Element 1 Silencing Transcription Factor as a central regulator of autophagy and neuroinflammation in Alzheimer's disease.\nAbstract: Repressor element-1 silencing transcription factor (REST) is a critical epigenetic regulator involved in multiple cellular processes, including apoptosis, autophagy, and neuronal survival. By modulating the expression of neuronal and stress-response genes, REST contributes significantly to neuroprotection. REST is predominantly localised in the nucleus; however, in Alzheimer's Disease (AD), nuclear REST is reduced, leading to transcriptional dysregulation and contributing to AD pathology. The low levels of REST are associated with defective autophagy flux, including mitochondrial dysfunction and enhanced vulnerability to toxic protein aggregates, causing AD and other neurodegenerative disorders. Recent research shows that REST suppresses several apoptotic genes, modulating neuroinflammatory signalling and regulates autophagy. The specific regulatory mechanism of REST suggests new strategies for the prevention and treatment of AD and ageing. Despite REST's unique functions and importance in AD, its precise role and the molecular mechanisms underlying REST-mediated signalling pathways have not been comprehensively reviewed. The purpose of this review is to provide an overview of the structural and functional characteristics of REST, explore the mechanisms underlying REST-mediated autophagy, neuroinflammation and apoptosis in AD and discuss the emerging therapeutic implications of targeting REST.\n\nID: 42488318\nTitle: APC alterations in papillary thyroid carcinoma: molecular mechanisms, clinical implications, and future perspective.\nAbstract: Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer which is characterized by a complex of molecular panels involving genetic and signaling pathway alterations. The major molecular driver of PTC is MAPK signaling pathway, including BRAF, RAS, and RET/PTC, but new evidence suggests the role of Wnt/\u03b2-catenin signaling pathway dysregulation in thyroid tumor development and tumor progression. The adenomatous polyposis coli (APC) gene as an important tumor suppressor gene that negatively regulates \u03b2-catenin, has attracted attention due to its role in familial adenomatous polyposis (FAP)-associated thyroid carcinoma. This review summarizes the structure and biological function of APC gene, its role in Wnt/\u03b2-catenin signaling pathway, and its contribution to the molecular pathogenesis of PTC. Furthermore, the contribution of germline and somatic APC alterations to FAP-associated thyroid tumors, and the molecular mechanisms linking APC dysregulation to thyroid carcinogenesis are discussed. In addition, we reviewed the potential diagnostic, prognostic, and therapeutic implications of APC-related molecular alterations, including their relevance to molecular testing, precision medicine, genetic counseling, and surveillance strategies. Despite the uncommon prevalence of APC mutations in sporadic PTC, some studies suggest the role of APC-related molecular abnormalities in tumor progression and the emergence of aggressive clinicopathological disease subtypes. In addition, APC mutations may have significant clinical value when integrated with other molecular markers of thyroid carcinogenesis. However, the definite clinical significance of APC mutations in PTC emergence is not fully understood, and additional prospective and translational studies are required to elucidate their biological and clinical advantages in diagnosis, prognosis, targeted therapy, and individualized patient management.\n\nID: 42487683\nTitle: Molecular Pathogenesis and Therapeutic Response of Diffuse Large B Cell Lymphoma Genetic Subtypes.\nAbstract: Diffuse large B cell lymphoma (DLBCL) is a clinically and genetically heterogeneous disease. Molecular profiling studies in DLBCL have identified three distinct disease subtypes using gene expression profiling, whereas mutation analysis of tumors has identified at least six separate subtypes. Although each classifier predicts clinical responses to immunochemotherapy and targeted therapies, molecular profiling is not universally performed or uniformly implemented. In this review, we focus on the biology of the LymphGen algorithm defined genetic subtypes revealed by genomic, transcriptomic, and single-cell profiling. We highlight recent advances in understanding the major drivers of disease and discuss how different mutations promote common hallmarks of cancer that are vulnerable to precision medicine agents.\n\nID: 42486577\nTitle: Oral squamous cell carcinoma (OSCC): An overview.\nAbstract: Oral cavity cancer comprises malignancies arising from anatomical sites within the oral cavity, including the gingiva, buccal mucosa, anterior two-thirds of the tongue (oral or mobile tongue), hard palate, floor of the mouth, retromolar area, and mucosal surface of the lip. More than 90% of oral cavity cancers are histologically squamous cell carcinomas (oral squamous cell carcinoma, OSCC). Combined with mucosal lip cancer, oral cavity cancer ranks as the 19th most common cancer globally, with approximately 390000 new cases and 190000 deaths annually. However, the burden of OSCC varies geographically, with Melanesia and South-Central Asia showing a much higher disease incidence. Despite advances in diagnostic and therapeutic approaches over recent decades, OSCC mortality has remained largely unchanged, with only approximately 55-60% of patients surviving 5 years after diagnosis. Tobacco use (both smoking and smokeless forms) and alcohol consumption are among the most important risk factors for OSCC. This book chapter aims to provide a general introduction to OSCC, including its epidemiology, associated etiological factors, a proposed model of molecular pathogenesis, the diagnostic pathway, common treatment modalities, and prognostic factors.\n\nID: 42482228\nTitle: Long-read transcriptome sequencing reveals isoform signatures in preeclamptic placentas.\nAbstract: Preeclampsia is a major pregnancy-specific multisystem disorder that affects a substantial proportion of pregnancies globally and is a significant contributor to maternal and neonatal mortality. The molecular pathogenesis of this complex disease, however, remains elusive. Long-read sequencing technologies, with their ability to produce long, continuous reads, offer enhanced resolution for genomic studies. This study utilizes this technology to reveal novel insights at the isoform level in preeclamptic placentas. In this study, we enrolled six participants, including three with normotensive pregnancies and three with preeclamptic pregnancies. By integrating Oxford Nanopore Technologies (ONT) long-read sequencing, Illumina short-read RNA-Seq, ATAC-seq, and Whole-Genome Bisulfite Sequencing (WGBS) of placental tissues, we generated an isoform-resolved transcriptome. We identified a total of 48,175 isoforms, encompassing 19,584 previously unannotated splice variants from known genes and 2,744 novel isoforms from the newly identified loci. Furthermore, we found that epigenetic modifications in promoter regions trigger alternative first exon usage, leading to additional novel isoforms of key preeclampsia regulators (e.g., ADARG1). This study expands the known transcriptomic landscape of the human placenta, revealing tens of thousands of previously unannotated isoforms. Integration of cross-platform validation and multi-omics datasets not only confirmed the robustness of these findings but also provided insights into their potential biological functions. The resources generated here establish a valuable foundation for future investigations into placental development and the molecular mechanisms of preeclampsia.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n  --- END ACTUAL ABSTRACT FOR 42398690 ---\n\n- ERROR: You cited ID: 42406382 for the quote: \"Spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model.\"\n  FACT: Strict Misquote Detected!

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues.\n  --- END ACTUAL ABSTRACT FOR 42406382 ---\n\n- ERROR: You cited ID: 42458007 for the quote: \"The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline.\"\n  FACT: Strict Misquote Detected!

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS.

However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses.\n  --- END ACTUAL ABSTRACT FOR 42488639 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation.\" (Source: 42489267)\n- \"In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case.\" (Source: 42399152)\n- \"Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset.\" (Source: 42387584)\n- \"Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model.\" (Source: 42447123)\n- \"Peripheral immune cell infiltration and crosstalk with brain-resident cells critically drive Alzheimer's disease (AD)-associated neuroinflammation, highlighting its therapeutic potential.\" (Source: 42489128)\n- \"In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease.\" (Source: 42484074)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Evidence confirms that while therapeutic SOD1-lowering strategies like tofersen and siRNA-conjugates show promise, outcomes can be heterogenous, and targeting non-SOD1 pathways remains a critical frontier.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis of recent literature indicates that SOD1-targeting therapies have achieved reliable reduction of protein levels in human central nervous system tissues. However, the diagnostic and prognostic landscape is increasingly reliant on multimodal biomarkers, including neurofilament light chain (NfL) and neuromuscular ultrasound, to manage the clinical complexity of SOD1-ALS and potential therapeutic failures in non-SOD1 patient cohorts.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic landscape for SOD1-ALS has undergone rapid evolution, marked by the clinical validation of antisense oligonucleotides (ASOs) and siRNA-based strategies. The distribution of tofersen in human central nervous system tissues has been confirmed, showing that \"In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model.\" While these molecular interventions show efficacy in reducing protein levels\u2014confirmed as \"The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study\"\u2014the clinical response can be paradoxical. Specifically, the risk of misapplication in non-SOD1 populations is documented, as evidenced by a case where \"In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease.\" Beyond traditional genetics, research now encompasses systemic modulators, where \"Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Macrophagic Inclusions:** Clinical monitoring of ASO therapy reveals frequent, persistent inclusions in cerebrospinal fluid, though their functional impact on therapeutic success remains debated.\n*   **Imaging Markers:** Neuromuscular ultrasound can detect structural changes in nerves and muscles at the same time as, or earlier than, conventional electrophysiological tests in SOD1 models.\n*   **Peripheral Autophagy:** Platelet Factor 4 (PF4) serves as a circulating neuroprotective regulator that restores proteostasis specifically in SOD1-driven ALS models.\n*   **Cellular Quality Control:** SGK1 has been identified as a target for modulating microglial phagocytosis, with its inhibition offering survival benefits in SOD1-G93A models.\n*   **Cross-Pathology:** NOP56 downregulation is an early feature of SOD1-G93A models, suggesting a broader involvement in motor neuron protein homeostasis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

        "39645085": "ID: 39645085\nTitle: Lipid nanoparticles and transcranial focused ultrasound enhance the delivery of SOD1 antisense oligonucleotides to the murine brain for ALS therapy.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease with extremely limited therapeutic options. One key pathological feature of ALS is the abnormal accumulation of misfolded proteins within motor neurons. Hence, reducing the burden of misfolded protein has emerged as a promising therapeutic approach. Antisense oligonucleotides (ASOs) have the potential to effectively silence proteins with gain-of-function mutations, such as superoxide dismutase 1 (SOD1). However, ASO delivery to the central nervous system (CNS) is hindered by poor blood-brain barrier (BBB) penetration and the invasiveness of intrathecal administration. In the current study, we demonstrate effective systemic delivery of a next-generation SOD1 ASO (Tofersen) into the brain of wildtype and G93A-SOD1 transgenic C57BL/6 mice using calcium phosphate lipid nanoparticles (CaP lipid NPs). We show that transcranial focused ultrasound (FUS) with intravenously administered microbubbles can significantly enhance ASO-loaded nanoparticle delivery into the mouse brain. Magnetic resonance imaging (MRI) and immunohistological analysis showed reduced SOD1 expression in the FUS-exposed brain regions and increased motor neuron count in the spinal cord of treated mice suggesting decreased motor neuron degeneration. Importantly, the BBB opening was transient without evidence of structural changes, neuroinflammation or damage to the brain tissue, indicating that the treatment is well tolerated. Overall, our results highlight FUS-assisted nanoparticle delivery of ASOs as a promising non-invasive therapeutic strategy for the treatment of ALS and CNS diseases more broadly.",
        "39730482": "ID: 39730482\nTitle: Genetic epidemiology of amyotrophic lateral sclerosis in Cyprus: a population-based study.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating, uniformly lethal degenerative disease of motor neurons, presenting with relentlessly progressive muscle atrophy and weakness. More than fifty genes carrying causative or disease-modifying variants have been identified since the 1990s, when the first ALS-associated variant in the gene SOD1 was discovered. The most commonly mutated ALS genes in the European populations include the C9orf72, SOD1, TARDBP and FUS. Understanding the genetic causes of ALS within a population is becoming more significant, especially in light of the possible development of personalized medicine. Here, we provide clinical and genetic data on familial and sporadic ALS patients in a Greek-Cypriot population-based cohort. Eighty-nine ALS patients, including 21 familial ALS (fALS) (23.6%) and 68 sporadic ALS (sALS) (76.4%), provided the cohort for variant screening of the most common ALS-associated genes. Moreover, next-generation sequencing (NGS) was also performed to identify rare ALS variants, and in silico prediction tools were applied to predict the downstream effect of the variants detected in our study. The pathogenic hexanucleotide G4C2 repeat expansion in C9orf72 was the predominant genetic cause (22.47%) of ALS in our population, while variants in six additional ALS-associated genes were identified, including ALS2, TARDBP, FIG4, TBK1, GLT8D1, and BICD2.",
        "40009238": "ID: 40009238\nTitle: Advancements in genetic research and RNA therapy strategies for amyotrophic lateral sclerosis (ALS): current progress and future prospects.\nAbstract: This review explores the intricate landscape of neurodegenerative disease research, focusing on Amyotrophic Lateral Sclerosis (ALS) and the intersection of genetics and RNA biology to investigate the causative pathogenetic basis of this fatal disease. ALS is a severe neurodegenerative disease characterized by the progressive loss of motor neurons, leading to muscle weakness and paralysis. Despite significant research advances, the exact cause of ALS remains largely unknown. Thanks to the application of next-generation sequencing (NGS) approaches, it was possible to highlight the fundamental role of rare variants with large effect sizes and involvement of portions of non-coding RNA, providing valuable information on risk prediction, diagnosis, and treatment of age-related diseases, such as ALS. Genetic research has provided valuable insights into the pathophysiology of ALS, leading to the development of targeted therapies such as antisense oligonucleotides (ASOs). Regulatory agencies in several countries are evaluating the commercialization of Qalsody (Tofersen) for SOD1-associated ALS, highlighting the potential of gene-targeted therapies. Furthermore, the emerging significance of microRNAs (miRNAs) and long RNAs are of great interest. MiRNAs have emerged as promising biomarkers for diagnosing ALS and monitoring disease progression. Understanding the role of lncRNAs in the pathogenesis of ALS opens new avenues for therapeutic intervention. However, challenges remain in delivering RNA-based therapeutics to the central nervous system. Advances in genetic screening and personalized medicine hold promise for improving the management of ALS. Ongoing clinical trials use genomic approaches for patient stratification and drug targeting. Further research into the role of non-coding RNAs in the pathogenesis of ALS and their potential as therapeutic targets is crucial to the development of effective treatments for this devastating disease.",
        "40475252": "ID: 40475252\nTitle: Inhibitory effect of Fisetin against the aggregation process of SOD1 E100K mutant: computer-based drug design as a potential therapeutic for ALS disease.\nAbstract: Protein misfolding and aggregation in superoxide dismutase 1 (SOD1) are linked to the neurodegenerative disease amyotrophic lateral sclerosis (ALS). SOD1 mutations have a significant role in the pathophysiology and fast behavior of protopathic proteins in ALS illness. The E100K mutation may be useful in uncovering the pathogenic mechanism of SOD1 associated with ALS. According to several studies, giving small molecule inhibitors made from polyphenolic flavonoid compounds may be a viable treatment strategy for neurological conditions. Using molecular docking and MD simulations, we have identified a potential flavonoid drug that may successfully inhibit SOD1's amyloidogenic activity. Puerarin, Fisetin, and Peonidin provided intriguing pharmacological hints during the initial screening of flavonoids. The Fisetin-E100K complex had a larger residual energy contribution and substantial binding than other flavonoid compounds. The findings showed that, unlike other materials, Fisetin increased the structural stability, hydrophobicity, and flexibility of the mutant while reducing the amount of \u03b2-sheets. Furthermore, to distinguish aggregation in the mutant (unbound/bound) states, we displayed modifications in the free energy landscape (FEL). As a result, Fisetin was identified as having therapeutic potential against the E100K, which might make it a viable pharmacological option for the creation of inhibitors that lower the chance of ALS death.",
        "41196070": "ID: 41196070\nTitle: Unraveling the genetic landscape of ALS in Greece: identification of known and novel causative variants in a 353-patient cohort.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset, progressive, fatal neurodegenerative disorder characterized by progressive loss of motor neurons. Approximately 15% of individuals diagnosed with ALS have a known genetic variant that contributes to disease. Herein, we present clinical and genetic data of a large Greek ALS cohort. The cohort consisted of 353 Greek consecutive index patients with ALS, including 16 patients with related motor neuron disease (MND) subtypes (nine with PLS, four with PBP, and three with PMA). Next generation sequencing raw data (obtained from the NYGC ALS Consortium) were further analyzed and used to screen for causative variants in known implicated genes. Repeat expansions in C9ORF72 and ATXN2 were investigated using ExpansionHunter software, repeat-primed PCR and fragment analysis. Pathogenic repeat expansions in C9ORF72 were detected in 41 patients (11.6%). In addition, 30 patients (8.5%) carried a causative variant in one of the genes studied. Known causative variants were identified in 27 cases (nine in SQSTM1, seven in TARDBP, five in SOD1, three in NEK1 and one each in SETX, VCP, FUS), whereas novel causative variants were identified in three cases (SOD1, FIG4, TBK1). In total, 71 cases received a molecular genetic diagnosis (20.1%). Additionally, seven cases (2.0%) carried an intermediate repeat expansion (30-33 CAG) in ATXN2. Our results reveal the distinct genetic profile of Greek ALS patients. These findings will have an impact on genetic counseling, the design of diagnostic gene panels for the Greek population and on genotype-specific therapeutic interventions. Understanding the genetic causes of ALS in different populations is becoming increasingly important, especially with the advent of personalized medicine.",
        "41599628": "ID: 41599628\nTitle: C16-siRNAs in Focus: Development of ALN-APP, a Promising RNAi-Based Therapeutic for Alzheimer's Disease.\nAbstract: This review examines a small interfering RNA (siRNA) designed for intrathecal (IT) injection, which reduces the formation of amyloid beta precursor protein (APP), a critical factor in the pathology of Alzheimer's disease (AD). The siRNA, designated ALN-APP, incorporates a 16-carbon chain (C16-siRNA) to enhance its delivery to the central nervous system (CNS) while leveraging advancements in specificity and duration of action based on previously approved drugs by the Food and Drug Administration. The development of ALN-APP involved a comprehensive analysis of the optimal carbon chain length and its conjugation position to the siRNA. Preclinical studies conducted on male Sprague Dawley rats, mice, and non-human primates (NHPs) demonstrated the efficacy of ALN-APP. In rats, an IT injection of C16-siRNAs at a concentration of 30 mg/mL, delivering a dose of 0.9 mg, resulted in cranial distribution via cerebrospinal fluid and led to a 75% reduction in copper-zinc superoxide dismutase 1 (SOD1) mRNA levels. These effects were dose-dependent and persisted for three months across multiple brain regions. Furthermore, studies in NHPs indicated that soluble APP levels were reduced to below 25%, sustained for two months. In the cerebrovascular amyloid Nos2-/- (CVN) mouse model of AD, administration of 120 \u00b5g of siRNA via the intracerebroventricular route produced reductions in APP expression, with mRNA levels remaining suppressed for 60 days in the ventral cortex. Indeed, ALN-APP controlled neuropathology in 5xFAD mice by significantly reducing amyloid levels and brain neuroinflammation, with improved behaviors in the elevated plus maze. Following these promising results in animal models, ALN-APP advanced to a Phase 1 trial, designated ALN-APP-001, which assessed its safety and efficacy in 12 participants with early-onset Alzheimer's disease (EOAD). Initial findings revealed a 55% reduction in soluble APP\u03b1 and a 69% reduction in APP\u03b2 by day 15. These exploratory findings require further validation with larger cohorts and proper statistical analysis. In a subsequent cohort of 36 patients, administration of the 75 mg dose via IT injection led to mean reductions of 61.3% in soluble APP\u03b1 (sAPP\u03b1) and 73.5% in soluble APP\u03b2 (sAPP\u03b2) after one month. These silencing effects persisted for six months and were associated with important decreases in A\u03b242 and A\u03b240 levels. These results highlight the potential of ALN-APPs to address Alzheimer's pathology while maintaining a favorable safety profile. Whether ALN-APP succeeds in further clinical trials, key challenges include ensuring accessibility and affordability due to treatment costs, the need for specialized intrathecal administration, and establishing infrastructure for large-scale production of siRNAs. In conclusion, advancements in ALN-APP represent a promising strategy to reduce beta-amyloid formation in AD, with substantial biomarker reductions suggesting potential disease-modifying effects. Continued development may pave the way for innovative treatments for neurodegenerative diseases.",

PubMed, MEDLINE, Google Scholar, and ClinicalTrials.gov were searched using the keywords: Qalsody, BIIB067, antisense oligonucleotides, SOD1, and amyotrophic lateral sclerosis. Articles published from inception to November 2025 were included. English-language studies assessing the pharmacokinetics, pharmacology, efficacy, and safety of tofersen were included. Prescribing information and real-world evidence were also reviewed. Tofersen is an intrathecally administered antisense oligonucleotide targeting superoxide dismutase 1 (SOD1) mRNA. Early trials demonstrate dose-dependent reductions in cerebrospinal fluid (CSF) SOD1 protein levels of -33% and slower ALS Functional Rating Scale (ALSFRS-R) decline compared to placebo (-1.19 vs -5.63 points). In Phase 3 trials, tofersen reduced CSF SOD1 by 29% and plasma neurofilament light chain (NfL) by 60%, while biomarkers increased in the placebo group. There was no significant difference in ALSFRS-R decline between tofersen and placebo (-6.98 vs -8.14; P = 0.97). Real-world data show favorable patient-related outcomes and improvement in ALSFRS-R. Adverse effects are primarily lumbar puncture related with serious neurologic events documented in 7% of tofersen recipients.Relevance to Patient Care and Clinical Practice in Comparison to Existing Drugs:As the first Food and Drug Administration (FDA)-approved gene-directed therapy for SOD1 ALS, tofersen directly targets the underlying genetic cause. Barriers include the need for genetic confirmation and intrathecal administration. Tofersen provides a promising targeted treatment option for pathogenic SOD1 ALS. Ongoing studies will clarify its long-term clinical impact.",

This review consolidates current insights into the roles of EVs derived from motor neurons, muscle fibers, and Schwann cells in regulating NMJ integrity. In healthy states, EVs deliver trophic factors, structural proteins, and regulatory RNAs that promote the clustering of acetylcholine receptors, presynaptic stability, and axonal growth. Motor neuron EVs carry Wnt7a, synaptophysin, and PGC-1\u03b1, while muscle-derived EVs deliver miR-206, agrin, and caveolin-3. Schwann cell EVs contribute neurotrophic support via NRG1 and GDNF. In contrast, diseased or aged NMJs exhibit EV cargo dysregulation, marked by the presence of misfolded proteins (e.g., SOD1, TDP-43), pro-inflammatory cytokines, and reduced regenerative miRNAs. These changes contribute to synaptic dismantling, neuroinflammation, and impaired repair in conditions such as ALS, SMA, MG, and sarcopenia. The review highlights the bidirectional nature of EV signalling and its dynamic regulation by neuronal activity and stress. Emerging therapeutic strategies include engineering EVs to deliver protective cargo, targeting them to NMJ components, and designing biomaterial-based depots for sustained release. Furthermore, EV signatures in blood and muscle hold promise as non-invasive biomarkers for early detection of NMJ decline in ALS, SMA, MG, and sarcopenia. Despite promising preclinical data, challenges remain in EV characterization, targeting specificity, and clinical translation. This review underscores a paradigm shift: EVs are not passive byproducts but active messengers of neuromuscular health and disease, with realistic applications in diagnostics, regenerative therapy, and personalized medicine.",

Targeting SOD1 expression represents a viable therapeutic strategy. Assess the safety and potential efficacy of SOD1 silencing by intrathecal administration of a U1 Adaptor oligonucleotide targeting canine SOD1 (U1cSOD1) in healthy and DM-diseased dogs. Seven purpose-bred healthy adult dogs, 1 dog with stage III DM and 4 dogs with Stage I DM. Healthy dogs and the stage III DM dog received a single intrathecal dose of U1cSOD1 or a vehicle and were euthanized 5 or 30\u00a0days later. Four stage I DM-affected dogs received monthly intrathecal injections of U1cSOD1 for up to 10\u00a0months. Physical and neurologic examinations, blood tests, cerebrospinal fluid analysis, as well as pharmacokinetic, pharmacodynamic, and histopathologic analyses were performed in all dogs. In dogs receiving U1cSOD1, spinal cord SOD1 RNA expression near the injection site was decreased to a median of 37% of normal (range, 21%-79%). Dogs tolerated the procedure and test agent well, exhibiting no adverse effects clinically or histopathologically. Two of 34 injections were aborted because of high intrathecal pressure. Monthly intrathecal injections of U1cSOD1 in DM-affected dogs are safe and decrease spinal cord SOD1 expression by >50% but an alternative administration route would be preferred. This first test of U1 Adaptor technology in dogs with a naturally occurring disease shows potential for therapeutic intervention in a fatal disease without a current cure.",
        "41821425": "ID: 41821425\nTitle: Tofersen treatment in SOD1 p.Leu145Phe ALS: real-world outcomes in a genetically homogeneous Croatian cohort.\nAbstract: Background: Antisense oligonucleotide tofersen targets SOD1 mRNA and reduces production of misfolded SOD1 protein, with demonstrated biomarker and functional signals in clinical trials and open-label extensions. Real-world reports from genetically heterogeneous SOD1 ALS cohorts describe variable functional trajectories. Data from genetically homogeneous founder populations remain limited. We investigated clinical trajectories in a cohort carrying the same pathogenic SOD1 variant to better characterize mutation-specific patterns in a real-world setting. Methods: We conducted a single-center observational study at the National Referral Center for Neuromuscular Diseases and Clinical Electromyoneurography (UHC Zagreb, Croatia). Eight adults with genetically confirmed SOD1 p.Leu145Phe ALS received intrathecal tofersen according to the approved regimen. ALS Functional Rating Scale-Revised (ALSFRS-R) scores were recorded at each dosing visit, and longitudinal slopes were calculated using linear regression. Safety and tolerability were evaluated descriptively. Biomarker and formal respiratory measurements were not routinely available. Results: All patients exhibited lower limb-onset, predominantly lower motor neuron phenotypes consistent with a slow-progressing founder variant. Median age at symptom onset was 60\u2009years, and median therapeutic delay was 48\u2009months. Median on-treatment ALSFRS-R slope was -0.28 points/month (range +0.04 to -0.57). Two patients demonstrated stable trajectories, while the remainder showed gradual decline. These patterns fall within the slower range reported in heterogeneous real-world SOD1 cohorts and are consistent with the known natural history of this mutation. Tofersen was well tolerated, with no serious treatment-related adverse events. Conclusions: In this genetically homogeneous SOD1 p.Leu145Phe cohort, functional trajectories during tofersen therapy reflected the mutation's slow-progressing phenotype. These findings provide real-world clinical context but do not permit conclusions regarding treatment efficacy. Further mutation-specific studies incorporating prospective baseline assessment and biomarker monitoring are needed to clarify therapeutic impact.",
        "41870290": "ID: 41870290\nTitle: Scalable assay to identify inhibitors of prion-like propagation of protein misfolding as potential therapeutics for neurodegeneration.\nAbstract: Protein misfolding is linked to many neurodegenerative diseases. In some cases, misfolding can propagate through a prion-like mechanism whereby natively folded molecules are converted into more copies of the misfolded isoform. Prion-like propagation of misfolding is an attractive therapeutic target, but difficulties with assaying conversion directly and simply have severely limited efforts to find drugs targeting conversion of disease-related proteins. Here, we demonstrate a scalable enzymatic assay for testing potential inhibitors of prion-like conversion in superoxide dismutase-1 (SOD1), whose misfolding is linked to amyotrophic lateral sclerosis (ALS). We tested several small-molecule inhibitors of SOD1 aggregation to determine if they also inhibited prion-like conversion. We found that some compounds, like telbivudine and cisplatin, did indeed significantly delay conversion, but others, like baicalein and quercetin, had little effect. Surprisingly, some compounds, like two statins tested, actually accelerated conversion, suggesting that they might act to promote ALS progression. These results underline the fact that conversion and aggregation are distinct biophysical processes. The ability of the assay to identify compounds effective at delaying prion-like conversion holds out promise for applications in future drug discovery efforts that target propagated misfolding specifically.",

To explore the genetic circuit by which the highly prevalent human opportunistic yeast Candida albicans controls sulfur utilization, we characterized the transcriptional landscape associated with sulfur starvation in this fungus. We identified many desulfonation enzymes that were differentially modulated and showed that Jlp12, a sulfonate/\u03b1-ketoglutarate dioxygenase, was critical for the utilization of different sulfur sources found in many niches of the human host. We also uncovered that the zinc-finger transcription factor Met32 acts as a master regulator, modulating genes involved in sulfur utilization, including Jlp12. Importantly, we found that C. albicans Met32 exclusively regulates sulfur utilization genes, while in the Saccharomyces cerevisiae lineage, it controls methionine biosynthesis. This work also identified Seo13 as the first major facilitator superfamily transporter in fungi to transport the alternative sulfur source glutathione, under the direct control of Met32. Furthermore, we showed that Met32 modulates C. albicans tolerance to sulfite excess by tuning the basal transcriptional level of the superoxide dismutase Sod1. This underscores the dual role of Met32 in the breakdown of sulfur-containing metabolites and the neutralization of the resulting reactive sulfur species (RSS). Our study delineates a new mechanism by which fungal pathogens utilize sulfur sources and neutralize RSS and underscores its importance in fungal fitness in vivo. Candida albicans is the most prevalent fungal colonizer of humans, and it is also the first cause of disseminated fungal infections leading to a high mortality rate. The ability of this yeast to metabolize a plethora of carbon and nitrogen sources inside the host is a critical asset for both the commensal and the pathogenic lifestyles of this yeast. Thus, these pathways represent attractive targets for antifungal therapy. While sulfur is an essential nutritional element for all living organisms, its contribution to fungal virulence remains understudied. Here, we describe new players of sulfur utilization metabolism in C. albicans and underline their importance in supporting fungal virulence. This work emphasizes the significance of targeting sulfur metabolic flexibility to manage fungal infections.",

In this study, we investigated the anticancer activity and molecular mechanisms of RS-PP-059, a derivative of 14-deoxy-12-hydroxyandrographolide, in colorectal cancer cells. RS-PP-059 exhibited potent cytotoxicity and selectivity toward HT-29 cells, suppressing viability and clonogenic growth. The compound induced apoptotic cell death, as shown by increased Annexin V-positive cells, PARP-1 cleavage, p53 activation, and \u03b3-H2AX accumulation, indicating DNA damage, and was accompanied by a reduction in total caspase-3 protein levels. Mechanistically, RS-PP-059 triggered endoplasmic reticulum (ER) stress and unfolded protein response (UPR), upregulating key markers including GRP78, IRE1\u03b1, CHOP, and spliced XBP1 (XBP1s) at both mRNA and protein levels. Co-treatment with the ER stress inhibitor 4-phenylbutyrate (4-PBA) only partially reversed these effects, suggesting robust ER stress activation by RS-PP-059. In parallel, RS-PP-059 increased intracellular reactive oxygen species (ROS) in a time-dependent manner, accompanied by differential regulation of antioxidant genes with strong induction of HO-1 and suppression of CAT, SOD1, and GPX-1. Importantly, pretreatment with N-acetyl-L-cysteine (NAC) abolished ROS accumulation, ER stress activation, apoptosis, and loss of viability, confirming the ROS-dependent mechanism. In conclusion, our findings demonstrate that RS-PP-059 exerts potent anticancer effects in colorectal cancer cells by promoting ROS-mediated ER stress, leading to DNA damage and apoptosis.",

Eyes from 6-8-week- and 9-month-old male and female C57BL/6J wild-type (WT) and xCT knockout (KO) mice -a model of accelerated aging-were examined with the Micron IV slit lamp, OCT attachments and iCare\u00ae TONOLAB. Droplet digital PCR was carried out to measure antioxidant genes SOD1, CAT, GPX1, GPX4, PRDX6, TXNRD1, GCLC, and GSR in WT and xCT KO corneas. Immunohistochemistry was used to visualise oxidative stress markers 4-Hydroxynonenal and 8-Hydroxydeoxyguanosine in the different layers of the WT and xCT KO corneas. WT and xCT KO corneas were transparent with age, with both showing an age-related decrease in IOP. Sex-dependent differences were seen in antioxidant genes between WT and xCT KO corneas. Male xCT KO corneas showed increased CAT, GPX1 and GPX4 at 6-8-weeks relative to WT. xCT KO corneas revealed increased GPX1 in both sexes at 9 months of age while female 9-month-old xCT KO corneas showed increased GPX4 compared to WT. TXNRD and GCLC was reduced in 6-8-week-old female xCT KO corneas. 4-HNE levels were unchanged, but 8-OhDG was elevated in xCT KO corneas across ages and sexes, especially in males and notably in the endothelium. This study reveals age and sex dependent differences in the expression of antioxidant defence genes and oxidative stress markers in the mouse cornea highlighting the importance of biological sex when studying corneal diseases that involve oxidative stress as an underlying mechanism.",

Aerobic exercise has been shown to improve NAFLD, although its underlying mechanisms remain incompletely understood. This study utilized ApoE-/- mice to investigate the role of Sestrin2 in aerobic exercise-induced amelioration of NAFLD. Methods: Random assignment of C57BL/6J and ApoE-/- mice yielded four groups: C (control), CE (aerobic exercise), AS (ApoE-/- control), and AE (ApoE-/- aerobic exercise). Aerobic exercise lasting 12 weeks was administered to the CE and AE groups. Serum biomarkers were analyzed by ELISA, liver tissue morphology was assessed via HE and ORO staining, and macrophage polarization was evaluated through immunofluorescence. Additionally, mRNA and protein expression levels were measured by qPCR and Western blot. Results: Aerobic exercise reduced liver wet weight, lipid accumulation, and steatosis in ApoE-/- mice. Aerobic exercise attenuates hepatic oxidative stress, and upregulated the expression of regulation oxidative stress related gene and proteins of Nrf2, HO-1, CAT, and SOD1 in ApoE-/- mice. Aerobic exercise promoted a shift in macrophage polarization from the pro-inflammatory M1 phenotype toward the anti-inflammatory M2 phenotype in the liver, and significantly reduced TNF-\u03b1 and IL-1\u03b2 levels, accompanied by upregulation of Sestrin2 expression, enhanced AMPK phosphorylation, inhibited mTORC1 in the liver. Conclusions: These findings suggest that aerobic exercise alleviates oxidative stress and inflammation in NAFLD, with Sestrin2 activation playing a central role.",

The usefulness of zebrafish in modelling human neurological disorders is supported by the similarity of their brains' anatomical and neurochemical characteristics, including comparable divisions of the forebrain, midbrain, and hindbrain, as well as dopaminergic, serotonergic, glutamatergic, and GABAergic pathways. Zebrafish have been used to successfully model several neurodegenerative diseases, including Alzheimer's disease (via tau phosphorylation and amyloid-beta aggregation), Parkinson's disease (via dopaminergic neuronal loss and alpha-synuclein pathology), Huntington's disease (via polyglutamine-expanded huntingtin), and amyotrophic lateral sclerosis (via mutant SOD1 and TDP- 43 transgenes). They have also been used to study multiple sclerosis, spinocerebellar ataxias, and Rett syndrome, enabling mechanistic exploration and preclinical drug discovery. This review crucially depicts how zebrafish models provide an affordable, morally acceptable, and scalable platform for early-stage neurodegeneration research. These models complement, rather than replace, rodent- and human-derived systems. Additionally, we will review how to bridge the gap between therapeutic screening and basic mechanistic findings, highlighting their increasing significance in the neuroscience research continuum.",

However, treating these disorders with conventional strategies is a major challenge. The approval of gene targeted therapy for spinal muscular atrophy (SMA) has laid the foundation for developing highly personalized therapies for other neurodegenerative disorders. As intensive research and efforts to advance gene targeted therapies continue, this review provides an overview of viral and non-viral vectors and delivery methods, as well as treatment strategies, including gene addition, replacement, editing, silencing, and splice modulation. Gene targeted approaches and clinical trials for SMA and amyotrophic lateral sclerosis (ALS) have demonstrated success, and additional studies are in progress. The design of efficient clinical trials which facilitate successful translation into clinical practice is of critical importance. Key considerations include the selection of appropriate disease models, understanding the natural history of the disease, and establishing well-defined outcome measures to assess prognosis of the disease and therapeutic efficacy. Finally, the precision of CRISPR-based gene editing offers the potential for one-time corrective therapies for monogenic disorders like SMA and SOD1-ALS.",

This study tested a photoelectrocatalytic (PEC) water treatment system, integrated into a standard recirculating aquaculture system (RAS), to improve water quality and evaluated ocular health in Oncorhynchus mykiss (rainbow trout) reared at 30 kg/m3 for 28 days, with particular emphasis on the cornea as an indicator of fish welfare. Ocular analyses focused on the cornea and retina, two anatomically and functionally distinct structures. PEC significantly reduced ammonia levels and modulated nitrate concentrations compared to the control group (CTR), represented by a standard RAS. No differences in growth performance or body condition were observed between groups. Corneal integrity was assessed using optical coherence tomography, histology, and mucous cell staining to evaluate epithelial structure and protective responses. Corneal tissue was examined to detect local oxidative effects through morphological analysis and immunohistochemistry for 8-hydroxy-2'-deoxyguanosine (8-OHdG). Alcian Blu-Periodic Acid-Schiff (AB-PAS) staining did not reveal significant differences in mucin-producing cells among groups. CTR fish exhibited epithelial disruption and increased 8-OHdG immunoreactivity, whereas fish reared in the RAS equipped with the PEC system, ensuring improved water quality, showed preserved corneal architecture despite mild oxidative stress. Molecular analysis of ocular tissues revealed no differential expression of oxidative stress-related genes, such as GPx1, GR, or sod1, in the two groups. Overall, these findings support the use of the cornea as a sensitive indicator of sublethal environmental stress in farmed fish and suggest that PEC treatment may contribute to improved water quality management and welfare monitoring in intensive aquaculture systems.",

Using a primary screening assay that monitors the function of this pathway, we prioritized a cyanobacterial extract from the Red Sea that decreased secretion of a bioluminescent reporter, Gaussia luciferase (GLuc), in living cells. A comparison of LCMS2 data against the GNPS database revealed a match for macrocyclic depsipeptide hoiamide A (1). Biological testing confirmed the ability of 1 to induce a mixed, non-lethal stress response in human U87-MG glioblastoma cells; analysis of stress markers by qRT-PCR revealed early upregulation of superoxide dismutase 1 (SOD1) and C/EBP-homologous protein (CHOP) relative to the control. Co-treatment of cells with 1 (100 nM to 3 \u03bcM) and antioxidant N-acetylcysteine afforded full protection from 1-induced decreases in GLuc secretion. We report that terminally differentiated human SH-SY5Y neuroblastoma cells, with a neuron-like phenotype, are highly sensitive to nanomolar concentrations of 1, whereas undifferentiated cells remained viable at 3 \u03bcM. These results expand the known biology of hoiamides and suggest that neurotoxic potential of 1 is likely due to an inherent failure of neurons to adapt to the loss of redox homeostasis and sustained ER stress.",

However, their oral supplementation is often limited by poor stability in the acidic gastric environment and low intestinal absorption. Here, we report the synthesis of methionine-coated-ZnO (Met-ZnO), ascorbic acid-coated Cu2O (AA-Cu2O), and dextran-coated MnO2 (Dex-MnO2) nanominerals, followed by encapsulation into pH-responsive microcapsules (NMs-MCap) for targeted intestinal delivery. The nanomineral mixture demonstrated strong antioxidant activity at physiological pH by scavenging superoxide radicals, hydrogen peroxide, and ABTS\u2022+ radicals. In intestinal epithelial (IEC-6)\u00a0cells, nanominerals significantly alleviated BSO-induced oxidative stress, reducing apoptosis, necrosis, and intracellular ROS accumulation. Oral administration of NMs-MCap in Zn, Cu, and Mn-deficient rats elevated mineral levels in blood and liver, mitigated BSO-induced oxidative damage, reduced lipid peroxidation and pro-inflammatory cytokines, and preserved tissue architecture. Importantly, oral supplementation restored SOD1 and SOD2 expression in key organs, supporting enhanced endogenous antioxidant defense. Metagenomic analysis revealed that mineral deficiency, combined with oxidative stress, caused gut dysbiosis, reducing beneficial taxa and enriching opportunistic ones. Nanomineral supplementation restored microbial balance, increased SCFA-producing bacteria, and improved antioxidant and metal-handling functions, establishing NMs-MCap as a safe, targeted antioxidant strategy supporting host health.",

This review provides an overview of fluid, imaging, electrophysiological, and genetic biomarkers, explicitly linking each modality to early detection, patient stratification, disease monitoring, therapeutic development, and clinical trial design. Fluid biomarkers (i.e., neurofilament light chain, phosphorylated neurofilament heavy chain, inflammatory cytokines, microRNAs, and proteins in blood or cerebrospinal fluid) reflect neuronal injury and/or disease activity, enabling early identification of pres-ymptomatic individuals and longitudinal tracking of neurodegeneration. Imaging biomarkers, such as structural and diffusion MRI of the motor cortex, corticospinal tracts, and spinal cord, as well as PET imaging neuroinflammation or metabolism, provide objective measures of MN degeneration and extra-motor involvement. Electrophysiological biomarkers, including high-density electromyography, motor unit number, transcranial magnetic stimulation, and electrical impedance myography, quantitatively assess upper and lower MN loss and functional reserve. Genetic biomarkers, encompassing variants in genes such as C9orf72, SOD1, FUS, and TARDBP, enable presymptomatic screening and molecular stratification. In this context, transposable elements have emerged as an additional layer linking genomic variation and RNA dysregulation. We highlight the importance of multimodal and stage-specific biomarker integration to improve diagnostic accuracy and illuminate distinct disease phases. This approach supports stratification by progression rate or molecular subtype, enrichment of clinical trial cohorts, and the development of surrogate endpoints. We conclude by discussing current challenges, including disease heterogeneity and assay standardization, and outline future directions toward biomarker-driven precision medicine in ALS.",
        "42125835": "ID: 42125835\nTitle: Tracking Protein Misfolding and Oligomerization: A Temperature-Controlled Ion Mobility-Mass Spectrometry Approach.\nAbstract: Aberrant protein oligomerization is a hallmark of neurodegenerative disorders, yet the conformational and kinetic underpinnings of early aggregation remain poorly understood due to the inability of structural techniques to capture transient, low-abundance oligomeric intermediates. This necessitates the development of a methodology that can characterize the conformational states related to protein unfolding and thus allow for the investigation of the molecular mechanism responsible for disease progression. Here, we demonstrate how temperature-controlled nanoelectrospray ionization (TC-nESI) combined with high-resolution ion mobility-mass spectrometry (IM-MS), surface-induced dissociation (SID), and limited proteolysis can be used to define the misfolding and oligomerization landscape of bovine Cu/Zn superoxide dismutase (SOD1). This integrative approach enables real-time detection of coexisting intermediates, and captures molecular events including metal-induced stability, monomer unfolding and assembly into heterogeneous soluble oligomers. Our results reveal that both holo- and apo-SOD1 undergo dimer dissociation followed by monomer misfolding and assembly into heterogeneous non-native oligomers, and that slow thermal ramping promotes the accumulation of misfolded monomers and higher-order complexes. Apo-SOD1 that lacks stabilizing metal cofactors, forms more compact and kinetically distinct oligomers via monomeric, dimeric and trimeric intermediates. Proteolysis and heat-induced fragmentation identify loops V, VI, VII, and the C-terminus as key labile regions contributing to oligomer interface formation, predominantly through hydrophobic interactions. Our findings establish a mechanistically rich model for early aggregation and demonstrate the capability of TC-nESI-IM-MS to temporally and structurally resolve misfolding transitions and oligomeric populations in a single experiment. This platform provides a framework to dissect oligomerization pathways relevant to neurodegenerative diseases.",

The mechanisms regulating TDP43 solubility remain incompletely understood. Here, we report that TDP43 undergoes S-acylation primarily at the Cys244 residue by the S-acyltransferase zDHHC23. This S-acylation maintains the liquid-like properties of TDP43 by reducing the aberrant interaction with poly(ADP-ribose) polymerase 1 (PARP1) and PARylated proteins, thereby countering the pathological condensation of TDP43. S-acylation-deficient TDP43 inclusions sequester the translational machinery and inhibit cytoplasmic protein translation, ultimately resulting in neurotoxicity. Importantly, TDP43 S-acylation is decreased in the familial ALS-associated TDP43 mutants as well as in SOD1-G93A mice and C9orf72-ALS induced pluripotent stem cell (iPSC)-derived neurons, suggesting the widespread involvement of TDP43 S-acylation in ALS pathogenesis. Our findings reveal an undescribed modification of TDP43 and provide deeper insight into the regulation of TDP43 pathological condensation in ALS.",

Although considered multifactorial with an unclear aetiology, it is believed that the interplay between genetic and environmental factors, with neuroinflammation playing a key role in disease progression, contributes to its development. There is currently no effective treatment for ALS. Curcumin has been recently highlighted for its potential therapeutic role in treating neurodegenerative diseases. Curcumin phospholipids, a highly bioavailable form of curcumin that allow the curcumin to be absorbed into the bloodstream more effectively than standard curcumin extracts, is considered as a natural cytokine-suppressive anti-inflammatory compound (CSAID) that is well-known for its therapeutic properties and is considered safe for humans and rodents at low to moderate concentrations. In this study, we investigated whether a long-term feeding regimen incorporating curcuminoids phospholipids-enriched diet early in disease progression could mitigate motor deficits and affect the lifespan of the SOD1 mouse model of familial ALS (fALS). Our results indicate sex-differences regarding the effect of curcumin supplementation on motor deficits and anxiety-like behaviour. While long-term feeding with curcuminoids phospholipids enriched diet had a complex effect on SOD1 female mice expressed as reduced anxiety like behaviour and motor deficits at the walking beam test, it had no effect on SOD1 male mice. Moreover, curcuminoids supplementation had a limited effect on disease onset and progression in SOD1 mice model for fALS.",

Ferroptosis, a new form of cell death resulting from iron-dependent lipid peroxidation, is closely related to cancer. However, whether CCS regulates ferroptosis in ovarian cancer is unknown, and its underlying mechanisms have not been reported. Here, we report that highly expressed CCS contributes to ovarian cancer tumor growth. Moreover, suppressing CCS induced ferroptosis in ovarian cancer cells and increased their sensitivity to ferroptosis inducers. Mechanistically, high CCS expression was found to reduce intracellular copper ion levels and increase Solute Carrier Family 7 Member 11 (SLC7A11) or Glutathione Peroxidase 4 (GPX4) expression by increasing p53 ubiquitination, thus affecting ferroptosis. Additionally, DC_AC50, a small-molecule inhibitor of CCS that targets its copper transport interface, regulates ferroptosis and ovarian cancer growth. Analysis of clinical data revealed a positive correlation between high CCS expression and high SLC7A11 and GPX4 expression in ovarian cancer patients. In summary, our study reveals that CCS protects ovarian cancer cells from ferroptosis by promoting SLC7A11 and GPX4 expression in a p53-dependent manner.",

However, copper dyshomeostasis-induced redox activity makes the brain vulnerable to oxidative and proteostatic stress. Cuproptosis, a recently characterized form of programmed cell death, is triggered by copper binding to lipoylated enzymes of the tricarboxylic acid cycle, resulting in proteotoxic stress, mitochondrial dysfunction, and cell death. Given that mitochondria are central to copper handling and the primary site of cuproptosis, we examine mitochondrial pathways and key cuproptosis-related genes. We also assess disease-specific signatures of copper imbalance. In Alzheimer's disease, excess copper binds to amyloid-\u03b2, promoting aggregation and neurotoxicity. In Parkinson's disease, copper-bound \u03b1-synuclein fosters aggregation, while copper-driven redox cycling elevates reactive oxygen species. Cuproptosis worsens mitochondrial vulnerability in Parkinson's disease and impairs cellular stress responses in Huntington's disease. In amyotrophic lateral sclerosis, superoxide dismutase 1-related defects compromise antioxidant defenses alongside copper-dependent mitochondrial dysfunction. In prion diseases, copper facilitates prion protein misfolding and toxicity. Across these disorders, common features include mitochondrial dysfunction and cuproptosis hallmarks-such as enhanced protein lipoylation, elevated reactive oxygen species, impaired electron transport chain activity, fragile Fe-S clusters, and increased reliance on the tricarboxylic acid cycle-which collectively increase neuronal susceptibility to copper dyshomeostasis. Clarifying and understanding the critical roles of copper metabolism not only elucidates the pathogenesis of neurodegenerative diseases but also offers alternative therapeutic strategies. This review uniquely integrates the mitochondria-centered cuproptosis axis with copper dyshomeostasis across Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, and prion diseases, mapping convergent vulnerabilities to mechanism-grounded interventions and outlining testable translational routes.",

Sirtuin 1 (SIRT1), a key regulator of oxidative stress and cellular senescence, may play a protective role against plastic-induced retinal injury, but its role remains unclear. In this study, human retinal pigment epithelial (RPE) cells and rat retinas were directly exposed to polystyrene microplastics (PS-MPs, 2\u00a0\u03bcm) and nanoplastics (PS-NPs, 50\u00a0nm), with and without SIRT activator SRT1720. In vitro analyses included cell viability, intracellular reactive oxygen species (ROS), SIRT1 expression, antioxidant enzyme levels (SOD1, SOD2, CAT), and senescence were assessed. In vivo, rats received intravitreal injections of plastic particles, with or without SRT1720 and oxidative stress-related markers, SIRT1 expression, and senescence were evaluated in retinal tissues 7 days after injection. Results showed that PS-MPs and PS-NPs reduced RPE cell viability in a dose- and time-dependent manner, suppressed SIRT1 and antioxidant enzymes, and increased ROS and senescence. PS-NPs induced stronger ROS and senescence than PS-MPs in vitro. Co-treatment with SRT1720 restored SIRT1 expression, improved antioxidant responses, and attenuated ROS and senescence. In vivo, both particle types induced retinal changes similar to those observed in cell experiments. However, there was no significant toxicity difference between PS-MPs and PS-NPs. In conclusion, PS-MPs or PS-NPs promote oxidative stress and senescence in RPE cells and retinal tissue via downregulation of SIRT1 and antioxidant defenses, while SRT1720 provides protective effects. These findings SIRT1 as a potential therapeutic target for plastic-induced retinal injury.",

Copper metabolism domain containing 1 (COMMD1), a gene implicated in copper homeostasis, has not been thoroughly characterized in the context of ALS pathogenesis. In this study, we identified elevated COMMD1 expression in ALS, potentially contributing to diminished copper incorporation into SOD1. Knockdown of COMMD1 enhanced palmitoylation of the copper chaperone for SOD1 (CCS), facilitating its membrane translocation and promoting copper loading into SOD1, thereby conferring neuroprotection in ALS. Mechanistically, we established that COMMD1 knockdown augments CCS palmitoylation via activation of the hypoxia-inducible factor 1 subunit alpha (HIF-1\u03b1)/fatty acid synthase (FASN) signaling axis. In vivo investigations utilizing male hSOD1G93A transgenic mice demonstrated that COMMD1 deficiency markedly ameliorated the deterioration of motor function and prolonged survival duration. These findings collectively suggest that COMMD1 represents a potential therapeutic target for ALS intervention.",

The review discusses the intricate pathophysiology of ALS, such as the alterations caused by the genetic mutations of the C9orf72 and SOD1 genes, the misfolding and aggregation of proteins, oxidative stress, the excitotoxicity of glutamate, neuroinflammation, malfunctions in mitochondria, and axonal transport. Heterogeneity of the disease makes the development of biomarkers in ALS challenging; however, some promising candidates have been identified. Protein aggregation markers, including TDP-43 and SOD1, oxidative stress markers, such as 8-oxodG, neuroinflammatory markers, such as CRP and MCP-1, and neurological injury markers, such as NfL and pNfH, have potential in diagnosis, monitoring, and prediction. The miRNAs and particular metabolites can also provide clues to the molecular basis of ALS. The creation of biomarkers is challenged by the presence of a significant amount of disease heterogeneity and the lack of animal model reliability. The review highlights the importance of further research on biomarkers aimed at improving the diagnosis, treatment, and development of drugs for ALS. It supports the concept of a systematic biomarker development process, including genetic testing and molecular subgroup analysis, to enhance diagnostic accuracy and prognostic prediction capabilities. Exploring the interrelationship between the pathological process of ALS and the treatment based on multi-biomarker strategies is crucial for achieving effective management of this disease. As our understanding of ALS deepens, we expect to discover more new biomarkers in the future. This will significantly improve the diagnosis, treatment, and overall management of this devastating diseas.",

Integrating scientific research with clinical informatics into clinical practice facilitates novel methodologies for patient care. Computational pathology is a burgeoning subspecialty in pathology that promises a better-integrated solution to histopathological images and clinical informatics. Deep-learning methods in computational pathology have demonstrated considerable advances in automated histopathological image analysis. However, convolutional neural networks (CNNs) face fundamental limitations when dealing with the significant morphological heterogeneity present in disease tissues. Conventional CNNs use fixed convolutional kernels, which restrict their effectiveness in adaptively extracting features from histopathological images that exhibit diverse pathological patterns, staining intensities, and tissue architecture. To address this substantial limitation, we present an optimized variant of Omni-Dimensional Dynamic Convolution (ODConv) networks for distinguishing diseased tissue from healthy tissue. Compared with prior dynamic convolution methods that attend to a single kernel dimension, ODConv applies multi-dimensional attention across spatial positions, input channels, output channels, and kernel candidates, enabling more flexible and adaptive feature extraction. We evaluated our approach on wheat-germ agglutinin-stained and hematoxylin and eosin-stained skeletal muscle images from multiple disease models, including G93A*SOD1 transgenic mice (amyotrophic lateral sclerosis) and Akita mice (Type I diabetes). ODConv, trained entirely from scratch without ImageNet pretraining, achieved competitive classification performance relative to seven fine-tuned pretrained architectures across both staining modalities, demonstrating the effectiveness of omni-dimensional dynamic kernels in learning discriminative morphological representations directly from domain data. The study reports strong statistical agreement metrics, proving effective class balance handling and stable decision boundaries. These findings confirm ODConv as a strong computational pathology framework that advances automated diagnosis of neurodegenerative and metabolic skeletal muscle disorders.",

However, chronic exposure to elevated fluoride levels has been linked to adverse neurological effects. Despite its widespread environmental presence, the molecular mechanisms underlying fluoride-induced neurotoxicity remain incompletely understood. This study aimed to elucidate the effects of fluoride on oxidative stress, endoplasmic reticulum (ER) stress, apoptosis, and associated histopathological alterations in brain tissue. Forty Sprague-Dawley rats were randomly assigned to four groups (n\u2009=\u200910 per group; 5 male\u2009+\u20095 female) and administered sodium fluoride (NaF) in drinking water at concentrations of\u2009<\u20090.5\u00a0ppm (control), 50\u00a0ppm, 150\u00a0ppm, and 300\u00a0ppm for 90 consecutive days. The expression of antioxidant genes (SOD1 and GCLC), ER stress, and apoptosis-related genes (XBP1, GRP78, BCL-2, and BAX) was quantified using real-time quantitative PCR (RT-qPCR), and histopathological analysis of the brain tissues was performed. Fluoride exposure caused a dose-dependent downregulation of antioxidant and ER stress-related genes and concurrent upregulation of the pro-apoptotic genes. Histopathological analysis revealed structural damage in hippocampus and cerebral cortex, including neuronal shrinkage, vacuolization, and apoptotic features. These findings indicate that prolonged NaF exposure impairs antioxidant defenses, induces ER stress, and activates apoptotic pathways, thereby contributing to neuronal damage. This study provides mechanistic insights into fluoride-induced neurotoxicity and highlights the need for further research on potential therapeutic strategies targeting oxidative and ER stress pathways.",

However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system.",

Mutations in the superoxide dismutase 1 (SOD1) gene account for approximately 2% of ALS cases and are associated with toxic protein misfolding and aggregation. Tofersen is an antisense oligonucleotide therapy designed to reduce the synthesis of mutant SOD1 protein through targeted mRNA degradation. While this strategy represents a gene-specific therapeutic approach for a subset of ALS patients, evidence regarding its efficacy, effectiveness and long-term outcomes continues to be evaluated in clinical trials and post-marketing studies. First, to describe the molecular mechanisms underlying SOD1-associated ALS and second, to analyze the therapeutic development, clinical outcomes, and regulatory evolution of tofersen. A narrative review was conducted in PubMed on preclinical and clinical studies published from 2016 through late 2025, complemented by an analysis of public registries and regulatory documentation. Clinical trials were identified through ClinicalTrials.gov and the Clinical Trials Information System (CTIS), and official reports from the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) were reviewed to contextualize their development and regulatory evaluation. Fifty-three publications were identified, of which 20 met predefined inclusion criteria after screening and full-text review. Preclinical studies showed reduced mutant SOD1 expression and prolonged survival in transgenic models. Phase I-II trials demonstrated safety, favorable pharmacokinetics, and dose-dependent reductions in SOD1 in the cerebrospinal fluid and plasma neurofilament light chain (NfL) levels. Although the phase III VALOR trial did not meet the primary ALSFRS-R endpoint (a validated questionnaire-based functional rating scale-revised for determining ALS disease progression) at 28 weeks, significant reductions in the surrogate biomarker NfL indicated target engagement and supported accelerated regulatory approval. Extension data suggested potential clinical benefit with early treatment. Ongoing studies, including ATLAS in presymptomatic carriers, and real-world European data support continued evaluation, alongside accelerated regulatory approvals by FDA and EMA. Tofersen marks a paradigm shift in ALS management, establishing the foundation for precision medicine in neurodegenerative diseases. Its ongoing evaluation in the ATLAS trial will determine whether early intervention can prevent or delay disease onset in presymptomatic SOD1 mutation carriers.",

Melatonin (MT) plays an important role in plant stress tolerance. This study examined how exogenous MT improves drought tolerance in red raspberry at the squaring stage. It focused on changes in photosynthetic performance, antioxidant capacity, leaves anatomical structure, gene expression, and hormone homeostasis. Drought stress significantly reduced photosynthetic performance, antioxidant enzyme activities, and hormone homeostasis in red raspberry, and altered leaves anatomical structure. Exogenous MT treatment, particularly at 150\u00a0\u03bcmol L\u207b1, effectively alleviated these drought-induced effects. MT increased net photosynthetic rate and stomatal conductance, reduced oxidative damage, and promoted osmotic accumulation. At the anatomical level, MT-treated leaves showed more compact spongy tissue, increased palisade tissue and leaves thickness under drought stress. Transcriptomic and metabolomic analyses further revealed coordinated molecular changes under MT treatment. These changes mainly involved photosynthesis, carbohydrate and starch metabolism, plant hormone signaling, and amino acid metabolism. Genes related to photosynthetic function (PNSL3 and PNSB4), carbohydrate metabolism (glgc and PYG), antioxidant defense (SOD1 and sodC), and auxin signaling (AUX1 and SAUR) showed marked expression changes under MT treatment. Metabolite profiling also revealed changes in sugars, amino acids, phenolic compounds, and hormone-related compounds. Several transcription factor families, including bHLH, MYB-related, NAC, WRKY, and ERF, showed strong responses to MT. These changes were associated with transcriptional regulation and metabolic adjustment under drought stress. Exogenous MT significantly improved drought tolerance in red raspberry at the squaring stage, with 150\u00a0\u03bcmol L\u207b1 showing the best overall performance. This protective effect was associated with improved photosynthetic performance, enhanced antioxidant capacity, and better maintenance of leaves structure. Integrated transcriptomic and metabolomic analyses further revealed changes in hormone-related and metabolic pathways. These findings indicate that MT enhanced drought tolerance in red raspberry through coordinated physiological, anatomical, and molecular responses.",

Brazilin, a bioactive compound from Caesalpinia sappan, has been reported to exert anticancer activities, yet its effects on intercellular communication under lipid-enriched conditions remain unclear. Here, we profiled brazilin-induced cytotoxic responses in HepG2 cells using real-time imaging-based monitoring of cell morphology, number, and area, together with viability assays. Brazilin reduced HepG2 viability in a concentration-dependent manner and suppressed pro-survival signaling (Akt phosphorylation and Bcl-2), accompanied by caspase-3 cleavage and increased Annexin V positivity, indicating apoptosis-associated cytotoxicity. We then isolated extracellular vesicles released from brazilin-treated HepG2 cells and confirmed exosome-like characteristics by TEM, exosomal marker expression (CD9/CD63/CD81), and nanoparticle tracking analysis. Notably, in palmitate/oleate-loaded HepG2 cells, exosomes derived from brazilin-treated cells modulated metabolic and stress-associated proteins, including reduced CPT1A and SOD1 levels and increased p27 expression, consistent with altered fatty-acid oxidation-related signaling under lipid accumulation. Collectively, these findings suggest that brazilin exerts direct cytotoxic effects in HepG2 cells and that exosomes released upon brazilin exposure may contribute to metabolic signaling changes in lipid-loaded cancer cells.",

However, its potential neurodevelopmental toxicity in aquatic organisms remains insufficiently characterized. In this study, zebrafish embryos were exposed to esketamine hydrochloride during early development, and its toxic effects were evaluated using an integrated framework combining developmental, behavioral, histological, transcriptomic, oxidative stress-related, and apoptosis-related endpoints. Early-life esketamine exposure altered multiple developmental indicators, including head length, eye depth, interocular distance, and body length, and disrupted locomotor regulation at later stages, particularly light-dark responsiveness and spatial preference. Histological examination further revealed exposure-related alterations in brain tissue organization. Transcriptomic profiling identified coordinated changes in pathways associated with redox homeostasis, protein synthesis, and phototransduction-related signaling. Targeted validation demonstrated significant upregulation of oxidative stress-related genes, including sod1 and sod2, while ELISA-based assays showed exposure-dependent alterations in SOD, CAT, GSH, and MDA levels. Acridine orange (AO) staining showed increased apoptosis-related fluorescence signals in the head region, with AO-positive puncta density differing significantly among groups. Integrative correlation analysis further linked developmental, behavioral, oxidative stress-related, and apoptosis-related endpoints. Notably, these effects occurred in the absence of overt lethality. Collectively, these findings demonstrate that esketamine interferes with neurodevelopmental and behavioral processes in zebrafish larvae and support the incorporation of early-life neurobehavioral endpoints into risk assessment frameworks for neuroactive pharmaceuticals.",

This study evaluated the protective effects of cashew apple bagasse (CAB) and its hydroethanolic extract (HECAB) in rats fed a high-fat, high-carbohydrate (HFHC) diet. The proximate composition of CAB and the phenolic profile and antioxidant capacity of HECAB were characterized. Male Wistar rats were assigned to four groups and fed for 19 weeks with a standard diet, an HFHC diet, or an HFHC diet supplemented with CAB or HECAB. Anthropometric, biochemical, histological, immunohistochemical, and immunoblot analyses were performed. HECAB showed high phenolic content and marked radical-scavenging activity, and untargeted UPLC-QTOF-MS analysis yielded 12 putative secondary metabolite annotations (levels 3-4) based on accurate mass, isotope distributions, MS/MS fragmentation patterns, and predefined acceptance criteria. Relative to the standard diet group, the HFHC diet induced metabolic and hepatic alterations consistent with early-stage MASLD. Compared with HFHC, both CAB and HECAB reduced serum insulin and HOMA-IR, attenuated hepatic steatosis, increased SOD1 and CAT, and reduced NF-\u03baB, IL-6, TNF-\u03b1, and IL-1\u03b2, whereas GPx1 remained unchanged. Both interventions also enhanced NRF2 and HO-1 compared to HFHC, with stronger nuclear positivity in the HECAB group, while CAB showed the clearest association with IL-10 restoration. These findings are consistent with modulation of antioxidant defense- and inflammatory-related pathways in early-stage MASLD and support further investigation of cashew apple bagasse as a valorized functional ingredient. However, because classical oxidative damage markers were not measured, these results should not be interpreted as direct evidence of reduced oxidative stress. In addition, the detected metabolites should be interpreted as putative annotations rather than definitive compound identifications.",

This study evaluated serum levels of 8-epi-prostaglandin F2\u03b1 (8-epi-PGF2\u03b1), an isoprostane generated through non-enzymatic lipid oxidation, and examined its relationship with antioxidant enzymes and clinical disease activity in ulcerative colitis (UC) and Crohn's disease (CD). Methods: Eighty-seven patients (55 UC and 32 CD) were assessed for serum 8-epi-PGF2\u03b1, superoxide dismutase 1 (SOD1), and glutathione peroxidase 1 (GPX1), and classified as having mild, moderate, or severe disease. Statistical analyses included comparative analysis, two-way ANOVA, multiple linear regression, and Ridge logistic regression. To address potential dietary confounding, total energy intake, Mediterranean Diet Score (MDS), and antioxidant supplement use were incorporated into the regression models. Results: Serum levels of 8-epi-PGF2\u03b1 and GPX1 were significantly higher in UC than in CD (\u03c1 = 0.001 and p = 0.042), and both increased with greater disease severity (p < 0.001 and p = 0.001). In UC, 8-epi-PGF2\u03b1 positively correlated with high-sensitivity C-reactive protein (hs-CRP), white blood cells (WBC), and Truelove-Witts Index (TWI), and negatively with hemoglobin (False Discovery Rate (FDR)-adjusted q < 0.100). In CD, it correlated with the Harvey-Bradshaw Index (HBI) and disease duration (FDR-adjusted q < 0.050). Inter-biomarker analyses showed a strong association between 8-epi-PGF2\u03b1 and GPX1 in UC (\u03c1 = 0.677, p < 0.0001, FDR < 0.0001), suggesting coordinated activation of oxidative and antioxidant pathways. The observed associations remained consistent after adjustment for dietary factors, supporting the robustness of the findings. Because these results are cross-sectional, they cannot establish causality and should be interpreted with caution. Conclusions: Nevertheless, 8-epi-PGF2\u03b1 emerges as a promising non-invasive biomarker for assessing oxidative stress and disease activity in IBD, with potential clinical applicability for patient monitoring and therapeutic evaluation.",

Previous studies have demonstrated that 2,2',4,4'-tetrabromodiphenyl ether (BDE-47), a prevalent congener, induces apoptosis, impairs phagocytic function, and triggers aberrant immune-inflammatory reactions in RAW264.7 macrophages via the induction of elevated intracellular reactive oxygen species (ROS). However, the underlying regulatory mechanism remains unclear. The nuclear factor erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE) signaling pathway is a key cellular defense system against oxidative stress. In this study, we investigated the role of the Nrf2/ARE pathway in BDE-47-induced macrophage immunotoxicity. Network toxicology analysis identified Nrf2 as a hub gene within the BDE-47-associated immunotoxicity network. Molecular docking and molecular dynamics simulations suggested a potential interaction between BDE-47 and the Keap1-Nrf2 complex, with moderate binding affinity. Experimental studies in RAW264.7 cells showed that BDE-47 exposure activated the Nrf2/ARE pathway, as evidenced by Nrf2 nuclear translocation and the differential upregulation of downstream genes (GCLC, GCLM, HO-1, NQO1, SOD1, and CAT). Importantly, Nrf2 knockdown via lentiviral shRNA or pharmacological inhibition with brusatol significantly exacerbated BDE-47-induced apoptosis and immune dysfunction, including enhanced pro-inflammatory cytokine production and impaired phagocytosis. These results demonstrate that Nrf2/ARE pathway activation represents an adaptive antioxidant response and contributes to limiting BDE-47-induced cytotoxicity and immune impairment in macrophages.",

While progress has been made in understanding molecular pathways involved in suicide, much more work is needed to identify clinically useful biomarkers of suicidality. Disturbed cellular proteostasis and aggregation of specific misfolded proteins are established pathological factors of neurodegenerative diseases. Increasing evidence also suggests that such aggregates often occur in patients with chronic mental illnesses. Recently, genes related to disturbed proteostasis showed differential methylation in individuals who died by suicide compared to controls. These include five genes encoding proteins that aggregate in neurodegenerative and/or mental illness: CRMP1 (also called DPYSL1), DISC1, MAPT (encoding the Tau protein), PRKN (also called PARK2, encoding Parkin), and SOD1. Given the possibility that altered methylation in these genes could affect expression of the proteins they encode, we aimed to review evidence for whether disturbed proteostasis may be a point of overlap between suicidality, neurodegenerative disease, and/or mental illnesses. Epigenetic changes in most of these genes also occur in other neurological disorders. Autophagy, and, to a lesser extent, the ubiquitin-proteasome system, are emerging as potentially impaired in individuals with suicidal tendencies and individuals who died by suicide. Based on this accumulated data, we hypothesise that disturbed proteostasis is likely to be a pathological component of suicidality. It is also plausible that this may lead to the accumulation of aggregated proteins in a similar manner to, and potentially overlapping with, those seen in major mental illnesses. If true, this would have consequences for potential identification of biomarkers for suicidality and should be a priority for future research in the field.",

While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS.",

We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression.

To analyze spatiotemporal cellular dynamics in amyotrophic lateral sclerosis, we performed single-nucleus ribonucleic acid sequencing and spatial transcriptomics analysis of cervical spinal cords from wild-type control mice and SOD1-G93A transgenic mice in the pre-symptomatic (d50), early symptomatic (d90), and late-stage (d130) phases of disease. Single-nucleus ribonucleic acid sequencing identified 17 cell clusters and showed that progressive neuronal loss occurred over time, paralleled by glial expansion. Spatial transcriptomics mapped these clusters anatomically onto oligodendrocytes in white matter, neurons in horns, and diffuse astrocytes/microglia. Subcluster analysis demonstrated neuronal heterogeneity, with early mitochondrial stress in ventral motor neurons evolving into synaptic dysfunction, transient maturation peaks in interneurons, and amplified age-related decline in amyotrophic lateral sclerosis. Astrocyte and oligodendrocyte subclusters, which were originally misclustered due to spot-level contamination, were reinterpreted to highlight A1-reactive states and progenitor expansions, validated by immunohistochemistry detection of serum/glucocorticoid regulated kinase 1. Temporal profiles tracked the transition from compensatory to inflammatory gliosis, while gene signatures were linked to human amyotrophic lateral sclerosis cohorts, including complement activation and mitochondrial dysfunction. This study provides a high-resolution spatiotemporal cellular map of amyotrophic lateral sclerosis pathogenesis through the integration of single-nucleus and spatial transcriptomics, uncovering early mitochondrial impairment in neurons, delineating the trajectory of neurotoxic glial states, and identifying compensatory progenitor responses, to highlight the highly intricate interaction between glial reactivity and neuronal susceptibility that drives the pathogenesis of ALS.",

Caffeic acid (CA), a dietary polyphenol, has demonstrated antioxidant and neuroprotective effects. This study evaluated the protective role of CA under diabetic-like conditions using an in vitro glucolipotoxicity model in HT-22 hippocampal neurons exposed to high glucose and oleic acid (HG\u2009+\u2009OA). CA was administered at low (5 \u00b5M) and high (25 \u00b5M) concentrations prior to HG\u2009+\u2009OA treatment. CA significantly enhanced neuronal viability and restored the expression of neurogenesis markers (Nestin, DCX, NeuN) and synaptic proteins (PSD-95, Synaptophysin). Furthermore, CA elevated antioxidant enzyme levels (Nrf2, catalase, SOD-1), regulated apoptosis through increased Bcl-2 and decreased BAX expression, and attenuated inflammatory responses. Pyroptosis was also suppressed, as evidenced by reduced gasdermin D (GSDMD) expression. These findings suggest that CA confers multifactorial neuroprotection against glucolipotoxic injury, and may serve as a dietary modulator for mitigating diabetes-associated cognitive decline in vitro.",

Previous studies revealed that the abnormal alterations of some non-motor neurons (non-MN) were a potential pathogenesis of sALS. Therefore, this study aims to search the potential evidences of non-MN in the pathogenesis of ALS via exploring potential relationships between 5-hydroxytryptamine (5-HT) neurons and the development of ALS. We employed fluorescent immunohistochemistry to investigate the altered distribution patterns of 5-HT and tryptophan hydroxylase 2 in the spinal cord and brainstem of Tg(SOD1*G93A)1Gur (TG) and wild-type (WT) mice. Additionally, we used western blot to analyze the expression levels of 5-hydroxytryptamine receptor 1A (5-HTR1A) and 5-HTR2A. Our findings revealed that 5-HT synapses were primarily distributed in the funiculus lateralis, anterior horn, posterior horn, central lateral column, and the area around the central canal of cervical, thoracic, and lumbar segments, and raphe nucleus as well as lateral paragigantocellular nucleus, and gradually reduced following age increase in WT mice. However, 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem gradually increased following the progression of disease and presented a significantly negative correlation between the increased distribution of 5-HT synapses and neurons and the reduction of neural cell number (positively correlated with the increase in neural cell death) at the onset and/or progression stage of TG mice. 5-HTR1A significantly increased, while 5-HTR2A significantly decreased at the onset stage of TG mice. Our study speculated that the distribution changes of 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem play a potential protective role in the pathogenesis of sALS through a compensatory 5-HT increase.",

Why these neurons are particularly vulnerable in ALS remains\u00a0unclear, as does why certain MN groups\u00a0remain resistant\u00a0throughout the disease course. We investigated the role\u00a0of the human leukocyte antigens (HLAs) and beta2-microglobulin (\u03b22m) in MN susceptibility to ALS, given their reported involvement in\u00a0both prolonging and shortening disease\u00a0progression. Loss of HLAs in ALS has also been\u00a0shown to increase MNs vulnerability to toxicity exerted by activated astrocytes. RNA\u00a0sequencing of control tissues\u00a0demonstrated that disease-resistant oculomotor neurons (OMNs) and Onuf's MNs exhibited \u03b22m and HLA mRNA levels comparable\u00a0to those of\u00a0vulnerable spinal MNs, suggesting that\u00a0baseline differences in these transcripts do not explain the differential vulnerabilities\u00a0of\u00a0these MN groups. However, HLA protein levels showed an inverse correlation with spinal MN size, with the large MNs, those lost early in ALS, displaying the\u00a0lowest HLA expression. HLA protein levels were also reduced in spinal MNs from\u00a0end-stage ALS patient\u00a0tissues, while remaining relatively\u00a0unchanged in OMNs. In contrast, spinal MNs uniquely exhibited significant upregulation of \u03b22m and HLA-C transcripts during disease, likely reflecting a protective compensatory response. Together,\u00a0these findings suggest that \u03b22m and HLAs may contribute to spinal MN\u00a0vulnerability in ALS. To assess their functional role, \u03b22m\u00a0knockout mice were crossbred\u00a0with SOD1G93A ALS mice. Loss of \u03b22m\u00a0did not alter life span\u00a0of the ALS mice, but led to\u00a0partial preservation of lumbrical muscle\u00a0innervation that\u00a0was insufficient to maintain motor function. Analysis of GFAP immunoreactivity revealed marked neuroinflammation activation\u00a0in the\u00a0spinal cords of \u03b22m knockout mice. As these mice retain normal MN numbers\u00a0and life-span, this indicates that loss of functional MHC-I, even in the presence of\u00a0astrocyte activation, is insufficient to cause MN disease. Furthermore, \u03b22m knockout significantly increased GFAP activation in SOD1G93A mice, but did not further exacerbate disease progression, suggesting\u00a0that loss of functional MHC-I does not necessarily render MNs more vulnerable to\u00a0astrocyte toxicity. Overall,\u00a0these findings indicate that \u03b22m and HLAs are dynamically regulated in ALS, and may influence MN vulnerability, but they are not major disease\u00a0modifiers in ALS.",

Here, we have profiled motor neuron microRNAs (miRNAs) during motor neuron degeneration in vivo to gain a better understanding of ALS pathophysiology. We demonstrate that one miRNA, miR-146a, is downregulated in diseased motor neurons despite upregulation in bulk tissue. Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit. A corresponding reduction in spinal cord gliosis but not motor neuron loss was observed. Finally, we observed that a proportion of miR-146a knockout animals develop spontaneous paralysis, motor neuron loss and chronic neuroinflammation with advanced age. Together these findings demonstrate that a single miRNA influences multiple aspects of motor neuron disease and highlights the complex role for neuroinflammation in ALS pathogenesis.",

This technique is an innovative technology that utilizes photosensitizers and generates active oxygen species. This study aimed to investigate the effectiveness of aPDT against multidrug-resistant (MDR) Pseudomonas aeruginosa using a nanoemulsion containing zinc phthalocyanine (NE/ZnPc) in a burn wound model under both in in vitro and in vivo conditions. Optimization of PDT conditions -across different drug concentrations, different incubation times, different doses of laser radiation -was performed in vitro, and then the anti-biofilm effects of the optimal concentration against clinical isolates of MDR P. aeruginosa were investigated. Under in vivo conditions, male rats were divided into seven groups: Control, burn wound group, bacterial-infected burn wound, infected burn wound with laser treatment, infected wound treated with laser and drug (optimal concentration), infected wound treated with drug alone, and infected wound treated with nanoemulsion alone. The area of the burn wound was measured at the beginning and end of the experiment. Pieces of skin tissue were collected to perform histological studies and measure the expression of EGFR and SOD1 genes. Based on the results, the drug at a concentration of 40 \u00b5g/mL encapsulated in nanoemulsion, a laser dose of 13 J/cm2, and the incubation time of 2 hours were selected as optimal conditions. Under these conditions, 80% biofilm inhibition was observed. According to the histological results, NE/ZnPc-mediated aPDT and laser radiation reduced the burn wound area, significantly accelerated the wound healing process, increased EGFR gene expression, and decreased SOD1 gene expression to normal levels. The promising antibacterial and anti-biofilm activity of NE/ClZnlPc-mediated aPDT against MDR P. aeruginosa, along with the increased expression of EGFR and SOD1 levels in infected rat wounds, indicate that this treatment may be served as an alternative approach to eradicate MDR bacteria.",

In this study, we investigated the acute and delayed effects of HS on the brain, kidneys, and liver of rats to identify molecular targets for therapy of the consequences of shock. Blood acid-base balance and electrocardiography (ECG) parameters were studied in rats in the acute phase of HS. Gene expression of antioxidant enzymes (Gpx1, Sod1, Cat, Nfe2l2) and inflammatory markers (Ptprc, Cxcl1, Cd86, Itgal, Il1b, Il6, Tnf, Tlr2, Cox2, Cst7, Ccl3, Il10) in brain, kidney, and liver tissues was analyzed, as well as the amount of protein markers for kidney damage (NGAL, KIM-1) in urine 24 h after HS. In addition, markers for the activation of astrocytes (Gfap) and microglia (Aif1) as well as neuronal markers (Eno2, Tubb3) in brain tissue were analyzed. Biochemical markers for liver and kidney damage and total antioxidant activity were determined in blood serum. Acute HS caused decompensated lactic acidosis, arterial hypotension and characteristic changes in the ECG. Although no pronounced inflammatory response was detected in brain, kidney and liver tissue in the late phase after acute blood loss, the brain and liver tissue were more susceptible to the adverse effects of acute blood loss than the kidneys according to a number of indicators. This points to the need to develop targeted strategies to protect organs in the postresuscitation period by targeting specific molecular targets in specific tissues.",

Human cerebral microvascular endothelial cells (hCMECs) were cultured and treated with 17\u03b2-estradiol (100 nM), the primary and most biologically active endogenous form of estrogen in humans, for 24 h. Intracellular reactive oxygen species production was significantly lower (\u223c15%; P > 0.01) in hCMECs treated with 17\u03b2-estradiol; however, antioxidant proteins superoxide dismutase-1 (28.6\u2009\u00b1\u200911.0 vs. 36.2\u2009\u00b1\u200911.9 AU) and catalase (33.6\u2009\u00b1\u200914.0 vs. 32.1\u2009\u00b1\u200914.7 AU) were not significantly altered by 17\u03b2-estradiol. Although, there were no significant differences in the basal intracellular expression of either total caspase-3 (159.8\u2009\u00b1\u200984.9 vs. 143.6\u2009\u00b1\u200939.2 AU) or active caspase-3 (13.5\u2009\u00b1\u20094.5 vs. 15.4\u2009\u00b1\u20096.7 AU) between untreated and 17\u03b2-estradiol-treated hCMECs; the increase in active caspase-3 in response to the apoptosis stimulus staurosporine was significantly lower (\u223c30%; P = 0.02) in 17\u03b2-estradiol-treated (from 15.5\u2009\u00b1\u20096.7 to 184.5\u2009\u00b1\u200943.8 AU) compared with untreated (from 13.5\u2009\u00b1\u20094.5 to 257.6\u2009\u00b1\u200934.4 pg/mL) hCMECs. t-PA release in response to thrombin was significantly higher (P = 0.02) in 17\u03b2-estradiol-treated (from 41.6\u2009\u00b1\u200910.8 to 61.1\u2009\u00b1\u20099.2 pg/mL; \u223c45% increase) compared with untreated (43.4\u2009\u00b1\u20099.2 to 48.0\u2009\u00b1\u200911.5 pg/mL; \u223c10% increase) hCMECs. In summary, 17\u03b2-estradiol decreases oxidative stress, enhances apoptotic resistance, and increases fibrinolytic capacity in human brain microvascular endothelial cells in vitro. Reduced risk of cerebrovascular disease and thrombotic events attributed to estrogen may be mediated, in part, by these beneficial endothelial effects.NEW & NOTEWORTHY The cerebrovascular protective effects of estrogen are diverse, complex, and not fully understood. This study provides novel data demonstrating that 17\u03b2-estradiol decreases oxidative stress, enhances apoptotic resistance, and increases fibrinolytic capacity in human brain microvascular endothelial cells in vitro. These changes in endothelial cell phenotype have been linked (clinically and epidemiologically) to less cerebrovascular dysfunction and reduced ischemic stroke risk.",

Oxidative stress-an excess of reactive oxygen species (ROS) over antioxidant defenses-may underlie LF remodeling, but tissue-level evidence is limited. LF from patients with LSS (n\u2009=\u2009180) and controls (n\u2009=\u2009102) underwent transcriptomic microarray and microRNA (miRNA) profiling, reverse-transcription quantitative PCR (RT-qPCR), enzyme-linked immunosorbent assay (ELISA), and biochemical assays of thiobarbituric acid-reactive substances (TBARS), total glutathione (GSH), and glutathione peroxidase (GPx) activity. Protein-protein interaction (PPI) and functional enrichment analyses were performed. Among 14,130 oxidative-stress-related transcripts, 8,197 were differentially expressed (p\u2009<\u20090.05). Redox-sensitive inflammatory mediators were upregulated, including tumor necrosis factor (TNF), interleukin-1\u03b2 (IL-1B), interleukin-6 (IL-6), and C-X-C motif chemokine ligand 8 (CXCL8), alongside mitogen-activated protein kinases (MAPK8/JNK1, MAPK14/p38\u03b1, MAPK1/ERK2) and superoxide dismutase 2 (SOD2) and peroxiredoxin-1 (PRDX1). Antioxidant defenses-catalase (CAT), superoxide dismutases SOD1/SOD3, glutathione peroxidase-1 (GPX1), and sirtuin-3 (SIRT3)-were downregulated. RT-qPCR confirmed these trends. ELISA demonstrated higher MAPK8 and IL-6 and lower SIRT3 and GPX1 in hypertrophic LF (all p\u2009<\u20090.05). Biochemically, LSS tissue showed increased TBARS and GPx activity and decreased GSH versus controls; oxidative imbalance intensified with greater pain and higher body mass index. Selected miRNAs (e.g., hsa-miR-3163\u2192MAPK8, hsa-miR-4291\u2192SIRT3) were reduced. PPI networks were highly enriched (p\u2009<\u20091\u2009\u00d7\u200910\u207b\u00b9\u2076). Notably, MAPK8, SIRT3, GPX1, and IL-6 dysregulation was independent of pain category. LF in LSS exhibits a persistent ROS-driven, MAPK-amplified inflammatory program with mitochondrial vulnerability (SIRT3 loss) and impaired peroxide detoxification (GPX1 decline). This oxidative signature likely sustains fibrosis and LF thickening and nominates MAPK8-SIRT3-GPX1-IL-6 as candidate biomarkers and therapeutic targets.",

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.",

Here we show that copper deficiency is a nutrient vulnerability in steatotic liver disease and that selective liver-targeted copper supplementation can reduce excess lipid accumulation. Analysis of steatotic patient and mouse tissues identify widespread alterations in hepatic copper homeostasis markers. Integrated multi-omics analyses reveal that copper induces lipolysis of PLIN2-containing lipid droplets while lipid importer CD36 is downregulated. We show that copper inhibits cAMP hydrolase activity of PDE3B, thus activating PKA-mediated HSL and AMPK activation upstream of lipolysis. Fatty acids liberated through lipolysis are subsequently degraded via enhanced mitochondrial fatty acid oxidation, supported by energetic rewiring toward oxidative phosphorylation (OXPHOS) with increased copper-dependent complex IV and SOD1 activity. Our findings establish a multi-pronged mechanism by which hepatic copper supplementation coordinately regulates lipid metabolism in response to steatosis and unveils a therapeutic metallomedicine strategy to rewire lipid regulation. Liver-targeted copper supplementation reduces diet-induced liver steatosis by dual activation of lipolysis and fatty acid degradation pathways.",

We examined synaptic plasticity, the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses, dendritic spine morphology, and the putative excitatory/inhibitory (E/I) ratio in the B2 barrel of the somatosensory cortex in female mice of an ALS mouse model. Transgenic mice, B6SJL-Tg (SOD1*G93A)1Gur/J, were used as the ALS model, and wild-type (WT) B6SJL/F1 mice served as controls. ALS mice were allocated to experimental groups based on disease stage (pre-symptomatic, onset, or terminal) and training condition (swim-trained or untrained). Swim training was applied after the first onset of symptoms (clinical score 1). We analyzed and quantified the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses and E/I ratios using serial electron micrographs to understand how these parameters change during disease progression and whether swim training influences this process. Our results showed stage-dependent alterations in asymmetric (putative excitatory) and symmetric (putative inhibitory) synaptic architecture in ALS. The obtained data showed an increase in the excitatory synaptic density in the presymptomatic ALS mice. This finding is consistent with previous reports of early cortical hyperexcitability and may reflect structural alterations associated with an initial increase in excitatory synapses before disease onset. Importantly, we report here an increase in inhibitory synapses at disease onset. TEM-based synaptic density quantification revealed reduced excitatory synapse density in the B2 barrel of the somatosensory cortex of trained ALS mice compared to WT controls, alongside a trend toward a reduced putative excitatory/inhibitory synaptic ratio. However, as no significant differences were detected between trained and untrained ALS mice, the contribution of swim training to these alterations remains unclear. Notably, swim training was not associated with detectable adverse effects on somatosensory cortex ultrastructure, excitatory synapse density, or the putative excitatory/inhibitory ratio, supporting previous observations that swim training is well tolerated under these experimental conditions. To our knowledge, these results provide the first TEM-based ultrastructural characterization of synaptic architecture in swim-trained SOD1-G93A mice, although further studies are needed to establish the underlying mechanisms and therapeutic relevance in ALS.",

Sixteen participants from a cross-sectional study were classified into high-fiber (n\u2009=\u20098) and low-fiber (n\u2009=\u20098) intake groups based on dietary assessment. Although these groups corresponded to vegan and omnivorous patterns, respectively, classification was based on fiber intake. Groups were matched for age, sex, socioeconomic status, while major dietary differences inherent to vegan and omnivorous patterns were explicitly considered in the interpretation. Stimulated whole saliva was collected under standardized fasting conditions. Human proteomic and microbial metaproteomic analyses were performed using bottom-up DIA-PASEF. Differentially abundant proteins, enriched pathways, and metaproteomic profiles were identified using bioinformatic analyses. From 3,332 identified proteins, 1,566 were quantifiable, and 66 were differentially abundant between groups (FDR [False Discovery Rate]\u2009<\u20090.05). Multivariate analyses revealed separation according to dietary patterns differing in fiber intake: high-fiber exhibited enrichment of homeostasis, lipid metabolism, and cytoprotective pathways, with increased abundance of PRP-1/2, CA6, APOA1, and HYOU1. Low-fiber showed enrichment of immune and oxidative stress pathways, with higher SOD1, GPX1, ANXA2, ANXA8, and S100A8. Metaproteomics analysis revealed no major taxonomic differences but greater interindividual variability in the low-fiber intake group. Dietary patterns characterized by different dietary fiber intake appear associated with distinct salivary proteomic signatures. Although the contribution of other co-occurring dietary factors cannot be excluded, these findings, based on a small, highly selected cohort, suggest that fiber-rich dietary patterns may support oral homeostasis through host-driven molecular pathways rather than major shifts in microbial composition. Our findings strengthen the rationale for considering dietary patterns with high-fiber intake not only as a systemic health determinant but also as a modulator of salivary molecular functions relevant to oral disease prevention and personalized care.",

There is limited information on cardiopulmonary effects of GSR specifically in a health relevant size fraction. This study evaluates the acute cardiopulmonary effects of GSR (particles \u22642.5\u202f\u00b5m; GSR PM2.5) and investigates the role of the receptor for advanced glycation end-products (RAGE) signaling cascade in the mediation of inflammation and oxidative stress using wild-type (WT) and RAGE knockout (RKO) mice. GSR PM2.5 collected during a law enforcement pistol training contained characteristic GSR markers (lead, copper, and 2,4- dinitrotoluene). Right ventricle measurements were lower in the GSR PM2.5 treated animals compared to the control indicating potential pulmonary vasodilation regardless of genotype. Lead content in the heart was significantly higher in the GSR PM2.5 exposed mice, indicating systemic circulation. Inflammatory markers (NF-\u03baB, TNF-\u03b1, SOD-1 and 2) in the lungs of RKO animals were significantly lower compared to the WT groups. The cardiovascular effects, differential inflammatory expression, and influence of RAGE signaling pathway on the cardiorespiratory response to GSR PM2.5 highlight the need for further investigation of longer exposure durations, mechanistic influences, and a more extensive chemical characterization of GSR PM2.5 in toxicological assessments.",

The P66R mutation in SOD1 destabilizes local structure and promotes \u03b2-sheet-driven fibrillation, which makes it a suitable model for exploring approaches for reducing pathogenic aggregation. Here, we evaluate silymarin, a polyphenolic compound with known antioxidant and neuroprotective properties, for its potential to inhibit P66R-hSOD1 aggregation. ThT fluorescence and transmission electron microscopy analyses demonstrate a significant decrease in amyloid fibril formation in the presence of silymarin; in addition, FTIR spectroscopy confirms the suppression of \u03b2-sheet formation. Fluorescence quenching and ANS binding assays indicate a moderate-affinity binding between silymarin and the mutant protein, along with a reduction in surface hydrophobicity. Hemolysis assays confirm its protective effect against membrane damage induced by aggregates, while molecular docking and dynamic simulations indicate that silymarin stabilizes aggregation-prone areas with hydrogen bonding and hydrophobic interactions, thereby promoting compact conformations and reducing solvent-exposed surfaces. The findings identified silymarin as an effective anti-amyloidogenic agent that reduces \u03b2-sheet accumulation and fibril formation while also decreasing cytotoxicity, highlighting its potential as a therapeutic candidate for ALS.",

Superoxide dismutase (SOD), a key enzymatic defence against reactive oxygen species (ROS), plays a central role in maintaining cardiovascular integrity through regulation of oxidative stress across cytosolic (SOD1), mitochondrial (SOD2) and extracellular (SOD3) compartments. Impairment of SOD function contributes directly to endothelial dysfunction, myocardial injury and vascular remodelling. Curcumin (Cur), a pleiotropic polyphenol derived from Curcuma longa, has emerged as a potent modulator of SOD activity and expression. Evidence from preclinical models consistently demonstrates that Cur enhances SOD-dependent antioxidant defences, thereby attenuating oxidative damage, inflammation, apoptosis and fibrosis across multiple CVD contexts, including myocardial infarction, cardiomyopathy, hypertension and diabetic complications. While Cur also influences additional signalling pathways, such as NF-\u03baB, PI3K/AKT and Nrf2, these effects are increasingly understood to converge on SOD-mediated redox regulation. Recent advances in nanodelivery systems have further improved Cur bioavailability and its capacity to modulate SOD activity in\u00a0vivo. However, despite robust preclinical evidence, clinical validation remains limited. This review synthesizes current mechanistic and translational evidence, positioning SOD as the central mediator of Cur's cardioprotective effects and highlights key gaps in clinical translation.",

This study investigated the toxic effect of different molecular weight PAHs on eukaryote model organism (Saccharomyces cerevisiae) exploiting oxidative stress biomarkers as endpoint indicators. Yeast cells were treated with environmentally relevant concentrations of phenanthrene (PHE), fluoranthene (FLA), and benzo[ghi]perylene (BghiP) for 24\u202fh. Benzo[a]pyrene (BaP) was used as a positive control. Subsequently, expression of genes related to oxidative stress responses, cytotoxicity via targeted analysis of antioxidant mutants, generation of reactive oxygen species (ROS), superoxide dismutase (SOD) activity, and glutathione (GSH) content were assessed. The results demonstrated that viability of S. cerevisiae was related to the molecular weight of PAHs. Oxidative stress related genes SOD1 and SOD2 were found to be prominently expressed. According to the redox mechanism of action, BghiP and BaP triggered ROS formation and induced an increasing activity of SOD. Furthermore, PAH exposure significantly affected the glutathione levels. In summary, PAHs clearly caused oxidative stress. Among PAH samples, the more benzene ring contained more toxicity level exerted in yeast cells.",

Heavy dependence on fungicides is neither sustainable nor environmentally safe, creating an urgent need for innovative strategies to enhance crop resilience. Defense priming, a phenomenon in which prior exposure to a mild stimulus enables plants to mount faster and stronger defenses upon subsequent stress offers a promising alternative. Pathogens or pathogen-derived molecules such as PAMPs and effectors are known to serve as effective priming stimuli in plants. In this study, we hypothesized that attenuated spores of B. sorokiniana could act as a priming stimulus to enhance resistance against spot blotch in wheat. By applying a low-dose spore suspension, we sought to establish pathogen-mediated priming as a green vaccination strategy, wherein controlled pre-exposure to attenuated inoculum enhances inducible resistance without imposing detectable growth penalties. Priming significantly reduced disease severity, with primed plants (P\u2009+\u2009B) showing a 2.6-fold lower percent disease index compared to non-primed controls (B). Biochemical analyses revealed enhanced photosynthetic pigments (Chlorophyll a 2.6-fold, Chlorophyll b 3.3-fold, Carotenoids 1.56-fold), increased antioxidant defenses (Superoxide Dismutase 1.4-fold, Catalase 1.4-fold, and Ascorbate peroxidase 1.5-fold, ascorbic acid 2.8-fold, proline 1.6-fold), reduced lipid peroxidation (4.1-fold decrease), and higher phenolic content (1.8-fold) along with elevated PAL (1.9-fold) and POX (1.5-fold) activity. Yield traits also improved, including 1.4-fold higher spike number, 2.0-fold greater spikelet fertility, and a 1.2-fold increase in thousand grain weight (TGW). Strikingly, these benefits were transmitted to the F1 generation, demonstrating that pathogen-mediated defense priming can induce intergenerational immune priming (IGIP). Taken together, our findings establish pathogen-mediated green vaccination as a sustainable strategy to enhance wheat resilience and provide durable protection against spot blotch.",

More than 40 genes have been implicated in familial ALS, which represents about 10% of ALS cases. Some genes, including C9orf72, SOD1, FUS and TARDBP are undoubtedly considered causative, but many others have uncertain pathogenicity and low penetrance. Here, we described the cases of two siblings affected by ALS and carrying both an ATXN2 heterozygous 32 CAG trinucleotide repeat expansion and a novel NEK1 heterozygous c.1674_1677dup. The segregation of both variants in this large family with thirteen siblings may support a role for these variants as susceptibility alleles within an oligogenic model. Our review of the literature suggests that NEK1 variants are frequently found in combination with other variants and repeats expansion in the ATXN2 gene appears to be more associated with monogenic ALS, but also frequently combined with C9orf72 repeat expansion.",

Oxidative stress, particularly reactive oxygen species (ROS), has been implicated in its pathophysiology, but direct human evidence remains scarce. Here, we evaluated ROS- and nitric oxide (NO)-related pathways in bladder mucosa from women with IC/BPS (n\u2009=\u20095) and controls (n\u2009=\u20097). Gene expression of NO-cGMP components, NADPH oxidases (NOX1-5), and antioxidant enzymes was assessed by qPCR. Baseline NO and superoxide (   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  ) levels were quantified using histochemical assays, and the effects of pharmacological inhibitors of NOS, iNOS and NOX enzymes were examined. IC/BPS samples displayed increased expression of PDE5A (3.1-fold) and p47phox (1.6-fold), along with reduced SOD1 expression (0.39-fold), consistent with an oxidative imbalance. Although baseline   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  did not differ between groups, NOS inhibition with L-NAME markedly reduced   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  generation, with a greater effect in IC/BPS tissue (85% reduction). Conversely, selective iNOS inhibition (1400\u2009W) increased   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  levels in IC/BPS biopsies. These findings suggest altered NOS-dependent redox regulation in the IC/BPS mucosa. Despite the limited sample size inherent to human biopsy studies, these results provide preliminary evidence of redox dysregulation in IC/BPS mucosa and highlight   O 2 -  $$ {\\mathrm{O}}_2^{-} $$  as a relevant mediator. They support further investigation into therapeutic strategies targeting NOS redox balance and cGMP signalling.",

EAM was induced in Dark Agouti rats by immunization with porcine myosin. Fifty animals were allocated to five groups: healthy controls, untreated EAM, and EAM treated with LBE (50, 100, or 200 mg/kg) for six weeks. Hemodynamic parameters were monitored, and echocardiography assessed cardiac structure and function. Inflammatory, oxidative, fibrotic, and apoptotic markers were analyzed. Immunological profiling revealed that LBE significantly decreased proinflammatory cytokines (IL-1, IL-6, TNF-\u03b1, IL-4, IL-17) while restoring anti-inflammatory IL-10 levels (p < 0.05). Antioxidant activity was confirmed by reduced levels of O2-, H2O2, and TBARS, accompanied by significant increases in SOD, CAT, and GSH activity (p < 0.05), and upregulation of SOD1 and SOD2 gene expression. Additionally, LBE (200 mg/kg) markedly reversed fibrotic remodeling through suppression of TGF-\u03b2 expression and collagen deposition, as shown by Sirius Red staining, and mitigated apoptosis by modulating Bax/Bcl-2 balance and reducing TUNEL-positive cells. Collectively, these findings suggest that LBE exerts strong cardioprotective effects in EAM by regulating inflammatory, oxidative, fibrotic, and apoptotic pathways, thereby preventing myocarditis progression toward DCM.",

Sanghuangporus sanghuang (SS), a medicinal fungus extensively studied in microbiology and biotechnology, is known to produce bioactive metabolites with antioxidant properties; however, its functional role in the auditory system has not been established. This study investigated the otoprotective potential of SS extract against oxidative and acoustic stress using complementary in vitro, ex vivo, and in vivo models. In H2O2-treated UB-OC1 auditory cells, SS (25-200 \u03bcg/mL) dose-dependently restored cell viability and significantly reduced intracellular reactive oxygen species accumulation. Western blot analysis demonstrated that SS suppressed the expression of apoptotic markers, including cleaved caspase-3 and cytochrome C. At the molecular level, SS upregulated Nrf2 and HO-1 expression at both mRNA and protein levels, without a significant change in Keap1 expression, indicating activation of endogenous antioxidant defense via the Nrf2/HO-1 signaling axis. Consequently, downstream antioxidant genes such as SOD1 and NQO1 were significantly upregulated. In ex vivo cochlear explant cultures, SS preserved hair cell integrity against H2O2-induced damage, as confirmed by phalloidin staining. In a murine NIHL model, oral administration of SS attenuated ABR threshold shifts, maintained Wave I amplitudes, and preserved the structural organization of outer hair cells across all cochlear turns. Collectively, these findings demonstrate that SS confers otoprotection by modulating the Nrf2/HO-1 antioxidant axis and mitigating oxidative stress-induced sensory cell injury, supporting the potential of SS as a fungal-derived functional bioactive resource for redox-associated cochlear protection.",

We previously showed in transgenic mice and postmortem human tissues that PC and PAD2 are altered in amyotrophic lateral sclerosis (ALS), a neurodegenerative disease characterized by motor neurons loss, paralysis, and death. Herein, we investigated the role of PAD2 in ALS by PAD2 knockout in a SOD1-ALS mouse model. To investigate the role of PAD2-induced citrullination in ALS pathogenesis, we generated PAD2 knockout (PAD2KO) in SOD1 G93A ALS mouse model and investigated the consequent modulation on the neuropathology and clinical symptoms, using molecular biology techniques such as qPCR, Western blotting, confocal microscopy, and electron microscopy. Additionally, we identified C3 as being citrullinated in human ALS using ionFinder. Our results show that PAD2KO blocked the increased PC and reduced myelin basic protein (MBP) aggregates in the ALS model. PAD2KO also improved motor neuron survival and the integrity of myelin, axons, and neuromuscular junctions, and reduced microgliosis in the white matter and C3 protein levels in astrocytes. Clinically, data from monitoring the body weight changes suggests that PAD2KO modulates the course of the disease in the ALS mouse model, accelerating the onset while slowing the progression after the onset, and modestly extending the survival of male mice. These results show that PAD2 is responsible for the increased PC in ALS and PC contributes to neuroinflammation and degeneration of motor neurons and myelinated axons. The modest modulation of the disease phenotype suggests that the role of PC in ALS is complex, involving altered PC in numerous proteins and in multiple cell types. Future studies are needed to investigate how PC modulates individual protein functions in various cell types to understand the contribution of PC to ALS pathogenesis.",

Chrysin (CHR) has multiple medicinal effects such as antioxidant, anti-inflammatory, and anti-apoptosis. This research seeks to investigate whether CHR can protect against pressure overload-induced myocardial remodeling and to explore the underlying mechanism. Transverse aortic constriction (TAC) surgery was conducted to establish a model of cardiac hypertrophy on male C57BL/6J mice. A model of cardiomyocyte hypertrophy in H9C2 cells induced by angiotensin II (Ang II) was also established. The results showed that CHR significantly improved survival and cardiac function, reduced myocardial hypertrophy and fibrosis, inhibited the expression of inflammatory mediators TNF-\u03b1 and IL-1\u03b2, suppressed cell apoptosis rate, downregulated the levels of Bcl-2 Associated X protein (BAX) and Cleaved-Caspase-3, and upregulated B-cell lymphoma/leukemia 2 (BCL-2) expression in TAC surgical mice or Ang II-treated H9C2 cells. CHR could also upregulate the levels of antioxidant enzymes SOD1 and HO-1 by mediating the nuclear translocation and expression of NRF2 to counteract oxidative stress response. The further mechanism investigation utilizing bioinformatics analysis and western blot revealed that the disease of heart failure is associated with the phosphatidylinositol\u20113\u2011kinase (PI3K)/serine/threonine-protein kinase B (AKT) signaling pathway. Collectively, our findings demonstrated that CHR might exert the improvement effects on pressure overload-induced myocardial remodeling with hypertrophy and fibrosis through regulating the PI3K/AKT/NRF2 pathway-mediated oxidative stress response to alleviate myocardial cell inflammation and apoptosis, suggesting that CHR may be a promising therapeutic agent for cardiac diseases induced by pressure overload.",

Prior to U.S. Food and Drug Administration (FDA) approval, tofersen was made available through expanded access protocol. This study describes the clinical and operational experience of administering tofersen through expanded access protocols at a single academic medical center in the U.S. Individuals with symptomatic SOD1(+) ALS (\u2265\u200918\u2009years), who were ineligible for traditional ALS clinical trials, received tofersen via bedside lumbar punctures at Massachusetts General Hospital. Treatment was provided through single-patient and intermediate-sized expanded access protocols prior to FDA approval. Demographic and clinical characteristics, referral-to-treatment timelines, safety outcomes, and operational costs were collected. Eleven individuals with SOD1(+) ALS received monthly intrathecal tofersen over a two-year period (July 2021 to July 2023). Most participants were female, and 81.8% had leg-onset ALS. The mean (SD) referral-to-first dose duration was 36 (22.4) days. A total of 120 doses were administered over a two-year period. Tofersen was safe and well tolerated, with no treatment-related serious adverse events. Operational costs totaled $336,620, supported by philanthropy and insurance.

Improving the stress resistance of sugarcane has always been one of the important directions in sugarcane breeding. Erianthus fulvus, a wild relative of sugarcane, exhibits remarkable stress tolerance. Therefore, fully exploring the excellent stress-tolerance genes in E. fulvus can provide important candidate genes for improving the stress resistance of sugarcane in future molecular breeding programs. The evolutionary characteristics of EfMYB124, a gene induced by low temperature and drought, were analysed. Moreover, the gene was successfully transferred into Arabidopsis thaliana, and the degree of damage, physiological responses, and stress-induced gene expression of the transgenic plants under stress were investigated. EfMYB124 is most closely related to At1R-MYB in group A1, and the members of this group have the potential to function in response to adverse stress. Numerous syntenic genes of EfMYB124 were identified in the sugarcane genome. Under drought and low-temperature treatments, the EfMYB124-transgenic plants exhibited relatively mild external damage. Moreover, the activities or contents of three antioxidant enzymes (CAT, POD, and SOD) and Pro in these plants increased rapidly, while the production of MDA decreased. Further analysis revealed that EfMYB124 could specifically regulate the expression of cold stress-related genes (CBF1, CBF3, COR15a, and COR4) and drought stress-related genes (RD29A, P5CS1, SOD1, and CAT2). Additionally, EfMYB124 represses the basal expression levels of key ABA signaling-related genes, including NCED3, ABI5, ABF2, and RD29B. In summary, this study has initially confirmed that EfMYB124 plays a positive role in regulating plants' resistance to drought and low temperatures. These key findings lay a solid foundation for us to further analyze the function of EfMYB and study its upstream and downstream interaction relationships. Meanwhile, they provide the necessary scientific reference for the future application of this gene in the genetic improvement of stress tolerance trait breeding in sugarcane.",

Research suggests that oxidative stress (OS) is critically implicated in its development and progression. Curcumin (Cur), a natural polyphenol derived from turmeric, exhibits potent antioxidant properties and has been extensively investigated for treating OS-related disorders. Consequently, this study aims to explore the potential of Cur to mitigate DBD. In vitro, a high glucose (HG)-stimulated bladder smooth muscle cell (BSMC) model was established and treated with Cur. Cell viability was assessed by Cell Counting Kit-8 (CCK-8) assay. Intracellular reactive oxygen species (ROS) levels and the apoptosis rate were measured by flow cytometry. Protein expression was evaluated using Western blot (WB) and immunofluorescence. In vivo, rats were fed a high-fat and high-sugar diet and then induced into a diabetic rat model using streptozotocin. Subsequently, Cur was administered to these rats by oral gavage. Bladder function was assessed through urodynamic testing and histopathological examination. Protein expression in bladder tissue was analyzed by WB. Cur demonstrated a protective effect against HG-induced injury in BSMC, enhancing cell viability and reducing ROS generation. It inhibited kelch-like ECH-associated protein 1 (Keap1) expression, thereby promoting the expression of nuclear factor erythroid 2-related factor 2 (NRF2) and its downstream effectors, heme oxygenase-1 (HO-1) and superoxide dismutase 1 (SOD1). Additionally, Cur decreased the apoptotic rate, suppressed the expression of B-cell lymphoma 2 (BCL-2)-associated X protein (BAX) and cysteine-aspartic acid protease 3 (caspase-3), and upregulated BCL-2. In diabetic rats, Cur ameliorated bladder dysfunction, as evidenced by reduced maximum micturition pressure and prolonged micturition intervals. Histological analyses revealed attenuated bladder tissue fibrosis and apoptosis, concomitant with suppressed Keap1 and elevated expression of NRF2, HO-1, and SOD1 in the bladder tissue. Cur alleviates OS and thereby ameliorates DBD in diabetic rats by regulating the Keap1/NRF2/HO-1 pathway, which highlights its therapeutic potential for DBD.",

About half of FUS-ALS (52.2%), but none of SOD1-ALS patients demonstrated pathological IFN scores. The IFN score significantly correlated with the ALSFRS-R slope and inversely with the time to severe event as a survival surrogate in this genetic ALS cohort.

Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.",

HS response in cattle reproductive cumulus cells remain understudied due to limited cell lines and comprehensive omics data. This study aims to establish immortalized cumulus cells from Hanwoo cattle as a HS model and explores their HS response using molecular markers including transcriptomics and proteomics approaches. Immortalized cumulus cells were established from primary cumulus isolated from fresh Hanwoo cattle follicles by using piggyBac transposon-mediated SV40T expression system. HS condition was optimized using reactive oxygen species (ROS) detection, quantitative reverse-transcription polymerase chain reaction, and Western blotting on oxidative and endoplasmic reticulum stress markers under different HS and recovery periods (4 h, 12 h, and 24 h). Transcriptomic and proteomic data were generated to identify HS-related differentially expressed genes (DEG) and proteins (DEP) utilized for gene ontology (GO) and pathway enrichment analysis. We established the first immortalized cumulus cell line with high specificity (99% CD44[+]) for in vitro HS study. ROS accumulation was observed at 4 h HS, leading to immediate upregulation of HSP70 and BiP proteins, with oxidative stress gene expression (SOD1, CAT, GPX1) peaked at 12 h HS. We identified 754 DEGs (fold change\u2265|2|) and 357 DEPs (fold change\u2265|1.5|) related to HS in the cumulus cell line. Enrichment analysis exhibited upregulation in GO and pathways related to protein unfolding and cellular response to HS, respectively, from both the DEG and DEP list. Downregulated DEG and DEP showed significant enrichment in GO related to the extracellular matrix, potentially affecting cumulus-oocyte complex communication for reproductive function. The cumulus cell line serves as a robust in vitro model for studying HS response in cattle reproductive system. The multi-omics data could help clarify the comprehensive HS response and identify possible molecular targets to mitigate negative HS effects in the future.",

This study investigated the potential of Lactiplantibacillus plantarum HY7715 to attenuate oxidative stress-induced neurobiological aging-related changes using H2O2-induced HT22 hippocampal cells and a restraint-stressed mouse model. In HT22 cells, HY7715 reduced reactive oxygen species accumulation, decreased 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels, and lowered the proportion of senescence-associated \u03b2-galactosidase-positive cells. These effects were accompanied by suppression of p53/p21 signaling and restoration of Tert expression. In restraint-stressed mice, HY7715 reduced the number of p21-positive cells in the hippocampus, significantly lowered p53 expression, restored Tert expression, reduced Il-6 expression, and improved antioxidant-related gene expression, including Gpx1 and Sod1. Microbiome analysis showed that HY7715 reshaped the stress-altered gut microbiota toward a Lactobacillus-enriched profile and reduced the abundance of Lachnospiraceae, Acetatifactor, Desulfovibrio, and Oscillibacter. Collectively, these findings suggest that HY7715 may attenuate oxidative stress-induced neurobiological aging-related changes by modulating senescence-associated molecular markers and stress-altered gut microbiota, highlighting its potential as a candidate for supporting healthy brain aging.",

Here, we present SKALE 2.0, a phase-resolved geometric deep learning framework that represents proteins as multimodal structural graphs and learns mutation-induced aggregation phenotypes directly from three-dimensional topology. Across SOD1, TDP-43, MAPT, and PRNP, SKALE 2.0 recovered a conserved latent transition from nucleation to elongation while resolving distinct mutation-specific phase sensitivities. Representative protein language model, AlphaFold-derived feature, and non-phase-aware structural baselines failed to recover both phase-dependent mutation modulation and phase separability, indicating that explicit phase conditioning is essential. The learned geometry showed that nucleation is preferentially coupled to buried hydrophobic perturbations, whereas elongation is shaped by solvent-accessible interfaces that support fibril propagation. This framework explains how pathogenic variants can remain globally folded yet acquire aggregation competence through localized structural rewiring. Recombinant SOD1 experiments validated predicted suppressor, enhancer, and phase-switch mutations, demonstrating that initiation and propagation can be tuned independently. SKALE 2.0 links atomic topology to phase-specific assembly kinetics and enables a constraint-aware design of aggregation suppressors.",

This study evaluated the impact of a commercial HS-based product on immunity and oxidative status of Apis mellifera. Newly emerged worker bees were kept under laboratory conditions and fed sugar syrup supplemented with 0.5% HS for seven days, while the control group received unsupplemented syrup. Effects of HS were evaluated by analysing the expression of selected immune-related genes, quantifying antimicrobial peptides (AMPs), measuring the activity of antioxidant enzymes, evaluating lipid peroxidation, and characterising hemocyte populations. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. HS supplementation significantly increased relative gene expression of superoxide dismutase 1 and prophenoloxidase, while expression of genes for apidaecin and defensin 1 decreased. Similarly, catalase enzymatic activity was significantly decreased in the HS group. No significant changes were detected in gene expression for other AMPs and relative abundance of AMPs, or other antioxidant parameters. HS supplementation significantly increased the proportion of medium granular hemocytes (p\u2009<\u20090.05) at the expense of high granular cells (p\u2009<\u20090.01). In conclusion, the 7-day administration of HS at 0.5% did not adversely affect bee health and modulated selected immune parameters. The biological significance of these immunomodulatory effects requires confirmation through challenge studies and field trials under natural conditions.",

The encapsulation efficiency of Nanofenac-L was >\u200997% with sustained drug release, releasing around 65% of the diclofenac in 48\u00a0h. The therapeutic potential of Nanofenac-L was evaluated in rat intervertebral disc-derived nucleus pulposus cells.\u00a0Nanofenac-L was found to be more effective than free Diclofenac Sodium (DCF-Na) in terms of anti-inflammatory activity, which was confirmed with significant suppression of COX-2 and Substance P. Furthermore, Nanofenac-L increased the expression of antioxidant genes in cells, such as SOD1, GPX1 and PRDX1. Preventive treatment was found to have shown therapeutic value whereas the curative treatment yielded a significant therapeutic effect indicating the possibility of Nanofenac-L to alleviate inflammation as well as to slow down disease progression. Altogether, these results suggest that Nanofenac-L could represent a promising long-lasting anti-inflammatory, pain relieving and antioxidant nanotherapeutic.

The mutations in the SPAST gene, which encodes the microtubule-severing protein spastin, are responsible for about 40% of all HSP cases. To date, the cellular and molecular mechanisms linking mutant spastin protein to UMN vulnerability in HSP patients remain unknown and there are no disease modifying therapies. To address this knowledge gap, we isolated pure populations of corticospinal motor neurons (CSMN; a.k.a. UMN in mice) from SPASTC448Y-UeGFP reporter mice at two pre-symptomatic time points and performed bottom-up proteomic analyses to reveal changes in their proteome that informs the underlying causes of their initial vulnerability. We find dynamic changes in their proteome and that limitations with cytoarchitectural integrity and stability of key organelles contribute to their neuronal vulnerability. Since the compound NU-9 was shown to improve similar cellular problems in CSMN that are diseased due to misfolded SOD1 toxicity and TDP-43 pathology, we further investigated its effect on the well-established pathological features of HSP that are recapitulated in the SPASTC448Y mice. We find that NU-9 treatment (100\u00a0mg/kg, for 100\u00a0days) significantly prevented degeneration of corticospinal axons, restored the integrity of mitochondria and endoplasmic reticulum, and reduced the presence of electron-dense accumulations in the CSMN of SPASTC448Y mice.",

Several recent genetic studies have found disease-causing variants in 50%-85% of patients with fALS and 10%-15% of those with sALS. The aim of our study is to review our clinical experience with sponsored genetic testing (i.e., pharmaceutical company-sponsored and cost-free to patient) since its inception. We reviewed the medical records on all ALS patients seen at our Center who consented to sponsored genetic testing from August 2021 through October 2025. Of the 170 medical records reviewed, 22 patients (12.9%) tested positive for a disease-causing variant in a known autosomal dominant disorder. Thirteen of 35 patients with fALS (37.1%) were found to have a disease-causing variant, in contrast to 9 of 135 patients (6.7%) with sALS. Of the 22 disease-causing variants found, the following genes were involved in decreasing frequency: C9orf72 11 (50%), SOD1 6 (27.3%), FUS 2 (9.1%), and one each (4.5%) of SQSTM1, TARDBP, and TBK1. Twenty-eight patients (16.5%) harbored 29 variants of uncertain significance (VUS). Results of testing led to medically actionable activities including genetic counseling for patients and at-risk family members with positive results, and treatment (i.e., intrathecal tofersen) for the two patients harboring pathogenic SOD1 variants. The lower diagnostic yields than previously published for fALS and sALS patients likely are related to lower numbers of genes tested in the sponsored genetic panels, and these are expected to improve as more genes are added.",

To contrast the effects of aging and oxidative stress on nerve conduction, synaptic transmission, and muscle excitability, we developed an easily accessible adult abdominal neuromuscular preparation, utilizing the male-specific Muscle of Lawrence (MOL) in Drosophila . The large size of MOL facilitated analyses of presynaptic nerve signals and postsynaptic responses that could result in sizable excitatory junctional potentials (EJPs) evoking full-blown muscle action potentials (APs) which were terminated rapidly by a characteristic afterhyperpolarization (AHP). Aged wild-type (WT) individuals (80 days or older) exhibited diminished neuromuscular transmission, mainly reflecting declines in motor axon conduction, with synaptic transmission remaining largely intact (since robust EJPs could still be evoked when nerve terminals were directly stimulated electrotonically). Additionally, muscle APs showed enhanced depolarizing peaks and weakened AHPs during current injection, suggesting weakening in repolarizing K + currents. Chronologically younger Sod1 mutants (up to 30 days) displayed similar trends of neuromuscular changes, confirming a major role of oxidative stress in aging. However, certain distinctions exist in muscle membrane properties and transmitter release machinery. A clear increase in muscle membrane resistance was seen in Sod1 but not in aged WT. Additionally, unlike normal spontaneous release of synaptic vesicles leading to miniature EJPs (mEJPs), extremely enlarged spontaneous transmitter discharges occurred in aged WT but was never seen in Sod1 , indicating a distinct, aging-specific alteration in transmitter release regulation. Notably, our work revealed considerable variation among individuals, ranging from transmission failure to largely intact neuromuscular functions, demonstrating the stochastic nature of functional declines due to aging and oxidative stress. Moreover, this study uncovered a well-defined common vulnerability, i.e. weakening of the Ca 2+ -activated BK current that caused drastic reduction in AHP in both aged WT and Sod1 mutants, as confirmed by their diminishing sensitivity to the BK channel blocker paxilline, which caused striking alterations in the AHP in WT control.",

Genes such as ACE, SOD1 and PER3 play important roles in regulating essential biological functions. These genes are involved in key physiological pathways, including blood pressure regulation, oxidative stress response and circadian rhythm maintenance, and genetic variants within them may influence susceptibility to cancer. Therefore, this study investigates the association between polymorphisms in the ACE, SOD1 and PER3 genes and the risk of breast cancer, with the aim of evaluating how these genetic variations relate to breast cancer susceptibility and clinical outcomes in Jordanian women. Blood samples of 300 women diagnosed with breast cancer, along with 300 healthy participants, were collected, and DNA was extracted from them. Genetic variants in the ACE (rs1799752), SOD1 (rs36232792) and PER3 (rs57875989) genes are examined through employing direct PCR to amplify the target regions. The ACE (rs1799752) variant was observed to be associated with breast cancer susceptibility, with the I/I genotype increasing risk of breast cancer (OR = 5.138, 95% CI = 1.38-19.03, p = 0.014). No associations were observed for SOD1 (rs36232792) and PER3 (rs57875989) variants. The rs1799752 polymorphism is suggested to have the potential of serving as a biomarker for breast cancer susceptibility in Jordanian women, as it is associated with elevating the risk.",

Although BAFF is a well-known protein in B-cell functions, its role in bronchial cell function remains undefined. Polyinosinic-polycytidylic acid (Poly (I:C)), a synthetic double-stranded RNA, serves as a model for viral infection that binds to toll-like receptor (TLR) 3 to trigger intracellular signal pathways. In this study, we investigated the effect of Poly (I:C)-induced BAFF expression on airway cell migration using Beas-2B human bronchial epithelial cells. Poly (I:C) increased BAFF expression and cell migration, along with the increased expression of N-cadherin, Vimentin and Slug (SNAI2), which are three primary markers for epithelial-mesenchymal transition (EMT). Cell migration was attenuated by small interfering RNA (siRNA) against BAFF, which also inhibited the expression of these EMT markers. Phosphorylation of c-Jun N-terminal kinase (JNK) was enhanced by Poly (I:C) and inhibited by SP600125, JNK inhibitor, leading to a decreased expression of BAFF and aforementioned EMT markers. Poly (I:C) increased reactive oxygen species (ROS), resulting in a ROS-dependent up-regulation of antioxidants (Catalase, superoxide dismutase (SOD)1 and heme oxygenase (HMOX)1) and Nrf2. Pre-treatment with N-acetylcysteine (NAC), ROS scavenger, inhibited Nrf2 activation and JNK phosphorylation. The increase in Nrf2 levels induced by Poly (I:C) was also attenuated by SP600125. Additionally, while NAC treatment inhibited BAFF expression, it caused little change in the expression of the three EMT markers. Increased BAFF expression was confirmed by Nrf2 binding to the BAFF promoter or an increase in the luciferase activity of BAFF promoter co-transfected with Nrf2 plasmids. Treatment with recombinant BAFF protein also increased cell migration and EMT marker expression. Taken together, our results demonstrate that Poly (I:C) promotes a regenerative migration of bronchial epithelial cells by inducing BAFF expression through the ROS-dependent JNK-Nrf2 signaling axis.",

Compounds 3a and 3b were tested utilizing the MTT study to evaluate their in vitro cytotoxic activity against healthy human embryonic kidney, lung cancer, breast cancer, and human liver cancer cell lines. It was determined that compound 3b exhibited high levels of cytotoxic activity against both liver and breast cancer cell lines, with IC50 values of 10.83 and 11.55 \u00b5M, respectively. Also, to elucidate the anticancer mechanism of compounds, pro-apoptotic BAX and BiD, anti-apoptotic BCL2 and BCL-xl, oxidant enzymes PRDX1 and SOD1 levels were examined by RT-qPCR. Moreover, cellular oxidative stress levels were spectrophotometrically measured, and cellular senescence was evaluated via the senescence-associated \u03b2-galactosidase test. DFT calculations and RDG, ELF, and LOL analyses were performed to demonstrate the reactivity of these compounds. Compounds significantly down-regulated anti-apoptotic genes, whereas mRNA levels of pro-apoptotic genes were up-regulated in MCF-7 cells. Moreover, oxidative stress status was significantly increased depending on the compound treatment. Consistently, PRDX1 and SOD1 levels were also significantly up-regulated. Furthermore, cellular senescence was significantly induced by the compounds. Fluorescence spectroscopy demonstrated strong binding of both compounds with CT-DNA, characterized by static quenching mechanism and binding constants of 6.02\u2009\u00d7\u2009106M-\u20091(for 3a) and 8.69\u2009\u00d7\u2009106M-\u20091(for 3b), suggesting an intercalative binding mode. In contrast, moderate affinity toward BSA indicated suitable transport characteristics with reduced nonspecific protein binding. Molecular docking studies supported the experimental findings. These combined results verify the potential of the synthesized derivatives as promising candidates for further investigation as biologically active anticancer agents.",

Vulnerable alpha motor neurons showed thousands of molecular changes, marking a transition into a distinct cell state we named \"disease-associated motor neurons\" (DMs). We identified transcription factor networks that govern how healthy cells transition into DMs and those associated with motor neuron subtype-selective vulnerability. Upregulation of DM-associated transcription factors in human motor neurons induced key features of DMs, demonstrating an active regulatory component. Human ALS spinal cord single-nucleus RNA sequencing data demonstrated conservation of the DM signature in alpha motor neurons, and human orthologs of regions differentially accessible in SOD1-G93A mouse motor neurons were enriched for ALS genetic risk variants. Together, these findings establish a conserved, genetically linked motor neuron signature in ALS.",

UPLC-MS analysis showed that anthraquinones and trans-THSG progressively decreased with increasing cycles and stabilized after five cycles, whereas cassialactone-8-O-\u03b2-D-glucoside and hyperoside emerged as new components during processing. In a low-dose LPS-sensitized mouse model mimicking immune-idiosyncratic liver injury, PMR processed for three or more cycles significantly alleviated liver damage. In an acetaminophen (APAP)-induced acute liver injury model, PMR processed for 5-7 cycles exhibited the strongest hepatoprotective effects. Spectrum-effect correlation analysis identified twelve constituents (e.g., emodin-8-O-\u03b2-D-glucoside) associated with liver injury, involving targets related to drug metabolism (CYP3A4), membrane transporters (ABCB1, SLC2A1), and oxidative stress (SOD1). Five components (e.g., cassialactone-8-O-\u03b2-D-glucoside) were linked to hepatoprotection, potentially through modulation of synthetic function (ALB) and inflammatory response (TNF, EGFR, HSP90AA1). The Cellular Thermal Shift Assay (CETSA) was employed to validate the molecular docking results, demonstrating that emodin-8-O-\u03b2-D-glucopyranoside and physcion-8-O-\u03b2-D-glucoside significantly enhanced the thermal stability of TP53. In parallel, emodin and hyperoside were confirmed to increase the thermal stability of albumin (ALB). Overall, processing PMR with black bean decoction for 5-7 cycles is optimal for reducing hepatic risk while preserving or enhancing hepatoprotective activity. These findings support a risk-benefit-oriented processing standard and propose candidate quality markers for standardized manufacturing, including trans-THSG, emodin, aloe-emodin, cassialactone-8-O-\u03b2-D-glucoside, and hyperoside.",
        "42343420": "ID: 42343420\nTitle: Immune checkpoint LAG-3 governs stage-dependent and disease-associated microglial modules in ALS model mice.\nAbstract: Immune checkpoint molecules, inhibitory receptors originally characterized in T cell biology, have recently emerged as regulators of microglial function in neurodegeneration, yet their roles in amyotrophic lateral sclerosis (ALS) remain unexplored. Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration.",

Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1\u03b2, \u03b3 interferon (IFN-\u03b3), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1\u03b2, IFN-\u03b3, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1\u03b2 and IFN-\u03b3 decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05).

While dexmedetomidine (DEX) exhibits acute neuroprotective properties, its long-term impact on developmental trajectories during recovery remains incompletely understood. This study examined whether a single neonatal dose of DEX modulates hippocampal neurogenesis following hyperoxia across defined postnatal stages. Six-day-old Wistar rats were exposed to 80% oxygen for 24 h and evaluated at postnatal days (P) 9, 11, and 14 after recovery in room air. Mechanistically, hyperoxia permanently triggered apoptotic cascades, evidenced by sustained transcript upregulation and increased histological apoptosis and cell loss across the cortex and hippocampus, while disrupting the hippocampal progenitor niche, suppressing key differentiation factors (Sox2, Tbr2, Prox1, Calb1) and altering mature NeuN expression. Likewise, markers for autophagy (Atg5/12, Beclin1), neurotrophins (BDNF, NGF, NT3), and plasticity markers (Nrp1, Sem3a) showed reduced expression. Proactive treatment with DEX (5 \u00b5g/kg) significantly reversed these detrimental patterns. First, DEX elicited a robust antioxidant response (Nrf2, SOD1, SOD3 induction). Second, DEX effectively suppressed hyperoxia-induced programmed cell death and tissue degeneration up to P14. Crucially, this dual protection sustained the neurogenic niche, safeguarding autophagy processes as well as neurotrophic and neuronal plasticity mediators, while showing excellent safety under normoxia. In conclusion, a single dose of DEX mitigates acute oxygen injury and exhibits beneficial, stage-specific effects within hippocampal neurogenic niches during the postnatal phase, highlighting its potential to preserve neurodevelopmental trajectories.",
        "42350385": "ID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.",
        "42351978": "ID: 42351978\nTitle: Loss of NRF2 During Aging Contributes to Myocardial Functional Decline.\nAbstract: Aging is a significant risk factor for cardiovascular diseases. The prevalence of heart failure increases with age, making it a leading cause of morbidity and mortality. We investigated age-associated changes in expression of Nuclear Factor (Erythroid-derived 2)-Like 2 (NFE2L2 or NRF2) in the myocardium of humans, rhesus monkeys, Fischer rats, and C57BL/6 mice. NRF2 is a transcription factor that orchestrates the expression of genes involved in antioxidant and detoxification responses. Analyses of RNA-seq data from the Genotype-Tissue Expression (GTEx) project, which contains left ventricular samples from 294 male donors, revealed a trend of age-associated declines in NRF2 transcripts and several of its downstream genes (SOD1, SOD2, CAT, GCLM, and AKR1B). Age-dependent decreases in NRF2 protein expression were observed in the myocardium of Rhesus monkeys and Fischer rats. To determine whether NRF2 loss contributes to myocardial aging, we evaluated cardiac function of NRF2 knockout mice (KO) at 19 and 24 months of age. At 19 months, the NRF2 KO mice exhibited diastolic dysfunction, characterized by an increased end-diastolic volume (EDV) and end-systolic volume (ESV), accompanied by a reduced ejection fraction (EF) and fractional shortening (FS), indicative of early onset of heart failure. The NRF2 KO mice displayed premature aging phenotypes and had reduced lifespans. Our findings support the trend of NRF2 signaling decline with age, and that loss of NRF2 accelerates the maladaptive cardiac remodeling and functional deterioration associated with aging.",
        "42351996": "ID: 42351996\nTitle: Metabolic Responses of Melanocytes and Melanoma Cells to UVA Radiation and Phytocannabinoids Exposure.\nAbstract: Ultraviolet A (UVA) radiation disrupts the redox balance of melanocytes and may lead to the development of melanoma, highlighting the need for new skin protection strategies. This study assessed the effect of phytocannabinoids [cannabigerol (CBG), cannabidiol (CBD), and CBG + CBD] on redox homeostasis in control and UVA-exposed melanocytes and in melanoma cells (SK-Mel-5). UVA radiation increased the activity of prooxidant enzymes in both melanocytes and SK-Mel-5 cells and, consequently, the level of reactive oxygen species (ROS) (approx. 2-fold). It also activated nuclear factor erythroid 2 (Nrf2), as reflected by increased expression of heme oxygenase 1 (HO-1) (melanocytes approx. 2-fold; SK-Mel-5 approx. 7-fold). Concomitantly, antioxidant mechanisms were impaired, as demonstrated by reduced superoxide dismutase (SOD1/SOD2) activity and impaired glutathione and thioredoxin function. These changes were accompanied by increased levels of oxidative damage markers (isoprostanes, 4-hydroxynonenal-4-HNE, and 4-HNE-protein adducts) (43-100%) and increased inflammatory signaling, including increased expression of nuclear factor kappa B (NF-\u03baB) subunits (melanocytes: p52 ~2-fold, p65 ~75%; SK-Mel-5: ~4-4.5-fold) and tumor necrosis factor alpha (TNF-\u03b1; ~30%). Phytocannabinoid treatment modulated these UVA-induced changes. In SK-Mel-5 cells, phytocannabinoids normalized the activity of prooxidant enzymes and consequently reduced ROS levels (~30%). They also reduced Nrf2 activation and HO-1 expression; however, CBG increased HO-1 level in melanocytes (~25-40%). Furthermore, phytocannabinoids enhanced antioxidant defense by increasing SOD activity, particularly in melanocytes (~10-40%), and restoring the glutathione and thioredoxin systems. Markers of oxidative damage were reduced by approximately 23-37% after treatment. Furthermore, phytocannabinoids attenuated NF-\u03baB activation (p52 ~18-28%, p65 ~25-29% in melanocytes; ~20% in SK-Mel-5), while TNF-\u03b1 levels remained unchanged. The effects in non-irradiated cells were modest (<15%). These results suggest that phytocannabinoid-mediated modulation of redox balance may stabilize melanocytes exposed to UVA radiation and potentially reduce the risk of neoplastic transformation. However, the observed protective effects in SK-Mel-5 cells require further investigation and detailed molecular analysis.",

Fruit Polysaccharides Promote Longevity in Caenorhabditis elegans via Modulation of SKN-1 and IIS Pathway.\nAbstract: In this study, polysaccharides from Ficus carica L. fruits (FCPs) were extracted using a deep eutectic solvent (DES)-based ultrasound-assisted extraction (UAE) method. The physicochemical properties of the FCPs were then characterized, and the anti-aging effects of FCPs were evaluated in Caenorhabditis elegans (C. elegans). It was demonstrated that FCPs significantly extended the lifespan of the nematodes, while improving locomotor activity without affecting the body size or reproductive capacity. Meanwhile, FCPs reduced lipofuscin accumulation, decreased intracellular reactive oxygen species (ROS) levels, and increased the survival of C. elegans under oxidative stress. Moreover, FCPs upregulated the expression of antioxidant genes sod-1, sod-3, ctl-2, ctl-3 and gst-4. The expression of skinhead-1 (skn-1), a homologue gene of mammalian nuclear factor erythroid 2-related factor (Nrf) in C. elegans, was also elevated upon FCPs treatment. Knockdown of skn-1 expression by RNA interference abolished the lifespan extension and ROS reduction in FCPs-treated C. elegans, indicating that the SKN-1-mediated signaling was essential for the anti-aging effects of FCPs. Additionally, FCPs caused downregulation of the key components of the insulin/IGF-1 signaling (IIS) pathway, age-1, akt-1, and akt-2. Overall, these results suggested that FCPs promoted longevity in C. elegans via modulation of SKN-1 and IIS pathway.",
        "42352031": "ID: 42352031\nTitle: Statin-Induced Coenzyme Q Deficiency Induces Metabolic Reprogramming in Astrocytes.\nAbstract: Statins are commonly used cholesterol-lowering drugs, but their effects on astrocyte oxidative metabolism are poorly understood. To investigate this, rat astrocytes were exposed to 200 nM atorvastatin or simvastatin for 6 days and then assessed for changes in coenzyme Q (CoQ) homeostasis, mitochondrial function, and energy metabolism. Both statins comparably decreased cellular CoQ9 and CoQ10 levels (~35%), with greater losses of their reduced antioxidant forms (60-75%). Lower intracellular and mitochondrial levels of reactive oxygen species (ROS) were accompanied by the upregulation of nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant pathways (superoxide dismutase 1 and glutathione reductase) and metabolic stress response factors, including hypoxia-inducible factor 1-alpha (HIF1\u03b1) and brain-derived neurotrophic factor (BDNF). Both statins promoted glycolytic reprogramming, mitochondrial fission, and biogenesis while impairing oxidative phosphorylation, as evidenced by reduced ATP-linked respiration, increased proton leak, and lower ATP levels. These findings suggest that statin-treated astrocytes adapt by prioritizing redox homeostasis over ATP production. CoQ10 supplementation increased cellular CoQ10 levels and restored ATP levels without further decreasing ROS, suggesting that its primary benefit is bioenergetic support, not additional antioxidant protection. Overall, statin-induced CoQ deficiency induces adaptive metabolic remodeling of astrocytes, while CoQ10 supplementation may help maintain energy metabolism under these conditions.",
        "42352067": "ID: 42352067\nTitle: Urate as a CO3\u2022- Scavenger and Regulator of SOD-1 and OGG1 Enzymes: Insights from DFT, Molecular Docking, and Molecular Dynamics.\nAbstract: The potency of urate, an abundant human plasma antioxidant, in preventing oxidative damage caused by the carbonate radical anion CO3\u2022-, was studied using quantum chemical calculations. The influence of microhydration of CO3\u2022-/CO32- and urate-/urate\u2022 couples on the thermodynamic and kinetics of the one-electron oxidation process was investigated. Depending on the degree of microhydration, the estimated rate constant for one-electron transfer is in the range of 2.0-7.3 \u00d7 109 M-1 s-1, in good agreement with the experimental value of 1.3 \u00d7 109 M-1 s-1. Modeling using vertical detachment energy and electron affinity, the driving forces of single electron transfer revealed urate(H2O)6- and CO3(H2O)9\u2022- clusters as the most likely existing species in water. Molecular docking revealed a favorable interaction of urate with the catalytic pocket of SOD1. Urate binds more strongly to the anionic active center of SOD1 than the reference inhibitor LSC-1, indicating its potency to prevent HCO3--supported CO3\u2022- formation. In contrast, the known OGG1 inhibitor TH13264 shows substantially stronger binding than urate, indicating urate's weaker affinity toward the DNA repair enzyme catalytic pocket. The molecular dynamics data indicate that urate binding does not destabilize either SOD1 or OGG1. In light of increasing evidence that the major source of oxidative stress could be CO3\u2022-, rather than the commonly assumed hydroxyl radical HO\u2022, the obtained results indicate the inherent ability of plasma to combat oxidative stress induced by this selective, milder oxidant. Such an ability with respect to the non-selective, highly reactive HO\u2022 does not exist in vivo.",
        "42353064": "ID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.",
        "42353187": "ID: 42353187\nTitle: Overexpression of Stanniocalcin 2 Protects Differentiated QM7 Cells from H2O2-Induced Oxidative Damage.\nAbstract: Oxidative stress, caused by excessive reactive oxygen species (ROS) accumulation, is a major factor in muscle cell damage and muscle atrophy-related disorders. Although Stanniocalcin 2 (STC2) is involved in cellular stress and exhibits cytoprotective effects in various cell types, its role in skeletal muscle cells during oxidative stress is unclear. This study investigated the effects of STC2 overexpression in quail muscle (QM7) cells exposed to H2O2-induced oxidative stress. STC2 expression was upregulated in non-transfected QM7 cells following H2O2 treatment. Stable STC2-overexpressing cells were differentiated for 4 days, and then assessed for cell viability, ROS accumulation, cell death, and myotube morphology following H2O2 treatment. Compared with control cells, STC2-overexpressing cells exhibited higher cell viability, reduced ROS accumulation, and decreased cell death. STC2 overexpression also attenuated the H2O2-induced reduction in MyHC protein expression. Antioxidant-related genes, including Superoxide Dismutase 1, Glutathione Peroxidase 1, Heme Oxygenase 1, and NAD(P)H Quinone Dehydrogenase 1, were significantly upregulated in STC2-overexpressing cells. Compared with the control cells, nuclear factor erythroid 2-related factor 2 protein levels were not increased in STC2-overexpressing cells under oxidative stress conditions. These findings suggest that STC2 overexpression alleviates oxidative stress-induced cellular damage and may contribute to protective antioxidant responses in muscle cells.",

This study investigated the impact of inflammation, vascular calcification, and statin therapy on redox balance in blood and carotid artery plaques, aiming to identify potential biomarkers for disease assessment. Thirty-two patients undergoing carotid endarterectomy provided 34 plaque samples. Enzyme activities in plaque/erythrocytes and -SH group concentration in plasma/plaque were measured. Pathological analysis was performed to determine inflammation/calcification grade, the presence of mast cells and plaque composition. The results showed that mast cells were associated with reduced non-protein -SH groups, indicating selective thiol consumption and serving as a qualitative marker of oxidative burden. Reduced catalase activity in erythrocytes was associated with advanced calcification, pointing to long-standing systemic oxidative stress. Statin therapy enhanced systemic superoxide-dismutase 1 activity, increased -SH groups, and modulated plaque-specific glutathione reductase activity, attenuating sex-related differences in redox regulation. These findings highlight the complex interplay between systemic and local oxidative processes in atherosclerosis through alterations in redox-related biomarkers such as plasma -SH group concentrations and catalase activity.",

Resveratrol, a natural polyphenol with antioxidant properties, has been proposed as a cytoprotective compound, although the molecular mechanisms underlying its effects remain incompletely understood. Here, we investigated whether the protective action of resveratrol against hydrogen peroxide-induced oxidative stress is mediated by adenosine receptor signalling and activation of the Nrf2 pathway in HeLa cells. Methods: Cells were treated with resveratrol alone or in combination with selective adenosine receptor antagonists and oxidant challenge, and cell viability, ROS production, receptor involvement, and Nrf2 expression and localization were analyzed. Results: Resveratrol at a non-toxic concentration significantly protected HeLa cells against oxidative damage, reduced ROS accumulation, promoted Nrf2 nuclear translocation and gene expression, and enhanced the gene expression of antioxidant enzymes such as SOD1, catalase, HO-1, and NQO1. Pharmacological blockade of the A2A receptor prevented this protective effect, whereas the inhibition of A1 and A3 receptors enhanced it and avoided the increased SOD1, catalase, HO-1, and NQO1 gene expression promoted by resveratrol alone. Moreover, A2A antagonism was associated with reduced PKA levels, consistent with the involvement of the cAMP/PKA signalling axis. Conclusions: Taken together, these observations support a model in which adenosine A2A receptor signalling contributes to resveratrol-associated cytoprotection and Nrf2 activation in a human non-neuronal cell model. Our findings therefore provide mechanistic insight into resveratrol-adenosine receptor interactions and generate hypotheses to be tested in disease-relevant neuronal systems.",

Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.",

However, the mechanisms underlying their antioxidative action remain largely unknown. In this study, the protective role of APS in H2O2-induced oxidative damage and associated mechanism were investigated in large yellow croaker head kidney (LYCK) cells. We found that the APS significantly inhibited H2O2-induced cytotoxicity, ROS accumulation, and mitochondrial damage, thereby alleviating subsequent apoptosis and pyroptosis. Further studies showed that APS activated the Keap1-Nrf2 antioxidant signaling pathway, thus up-regulating the downstream antioxidant genes (SOD-1, CAT, HO-1, and GR), enhancing SOD-1 and CAT activities and T-AOC level, and decreasing MDA content. Mechanistically, APS activate this antioxidant signaling pathway by inducing the expression of microRNA-183 (miR-183-5p). The produced miR-183-5p binds to the 3'UTR of Keap1 mRNA and promotes its degradation, leading to consequent Nrf2 activation. Our results therefore unveil the mechanism by which APS alleviate oxidative damage in a fish cell model, and provide the theoretical basis for their application in aquaculture.",

As most clinical trials were performed in Type 2 DM, the effects of SGLT2 inhibition in Type 1 DM are not completely clarified. To evaluate the effects of long-standing SGLT2 inhibitor dapagliflozin on the protein profile in rats with a Type 1 DM model. Male Wistar rats were divided into Control (C), DM, and DM treated with dapagliflozin (DM+DAPA) for 30 weeks. DM was induced by a single injection of streptozotocin (40\u202fmg/kg); dapagliflozin was added to chow (5\u202fmg/kg/day). Label-free mass spectrometry was used to assess left ventricular proteome. The bioinformatic tools used were STRING, Cytoscape, Cluster Marker, and ClueGO. ANOVA and Tukey or Kruskal-Wallis and Dunn. Dapagliflozin attenuated body weight loss (C 574\u202f\u00b1\u202f43; DM 339\u202f\u00b1\u202f31*; DM+DAPA 413\u202f\u00b1\u202f30*# g; p\u202f<\u202f0.05 * vs C; # vs DM) and reduced glycemia [C 108 (101-111); DM 554 (529-562)*; DM\u202f+\u202fDAPA 343 (237-416)*# mg/dL; p\u202f<\u202f0.05 * vs C; # vs DM]. Most proteins identified in the networks downregulated in DM vs C were upregulated in DM\u202f+\u202fDAPA vs DM. Proteins related to energy metabolism (CKm, Ak1, Atp5pf, Mdh1, Idh2), excitation-contraction coupling (Actc1, Casq2, Serca1, Serca2a), and oxidative stress (Sod1, Sod2) were upregulated in DM\u202f+\u202fDAPA. KEGG pathways enriched in DM vs Control included gap junction, necroptosis, and fatty acid degradation (upregulated), and Alzheimer's disease, cardiac contraction, and glycolysis/gluconeogenesis (downregulated). In DM\u202f+\u202fDAPA vs DM, upregulated pathways included Parkinson's disease, cardiac contraction, citrate cycle, necroptosis, and cyclic guanosine monophosphate-dependent protein kinase (PKG) signaling pathway; downregulated proteins were linked to ketone body metabolism.

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care.",

Current treatment still relies largely on broad immunosuppression, underscoring the need for mechanism-informed target discovery across GN phenotypes. We performed a program-guided integrative multi-omics study by combining cis-expression quantitative trait loci and cis-protein quantitative trait loci with GN genome-wide association datasets from UK Biobank, the GWAS Catalog, and FinnGen. Candidate genes were organized into four predefined mechanistic programs: cytokine/TNF signaling, cell-cycle/senescence-repair balance, complement/innate immune activation, and regulated cell-death/redox stress. Six GN-related outcomes were analyzed. Bayesian colocalization, cross-dataset meta-analysis, mouse knockout annotation, drug-repurposing assessment, network pharmacology, and rule-based evidence scoring were used to refine target prioritization. Integrative screening identified 42 transcriptomic and 12 proteomic putative targets, with the strongest enrichment in non-proliferative glomerulonephritis and primary membranoproliferative glomerulonephritis. Bayesian colocalization supported PPP2R1B in non-proliferative glomerulonephritis, SOD1 in IgA nephropathy, and CDK4 in primary membranoproliferative glomerulonephritis. Among 42 transcriptomic gene-outcome pairs taken forward, 11 were supported by cross-dataset meta-analysis. Proteomic meta-analysis supported several cross-dataset signals, including protective associations of ANXA5, GSR, and TNFRSF1B with glomerulonephritis. Across outcomes, complement/innate immunity and cytokine/TNF signaling formed the dominant shared backbone. After separating MHC-region signals for cautious interpretation, 31 non-MHC targets were retained for primary prioritization, with PPP2R1B, CDK4, and SOD1 comprising the top tier. This mechanism-centered integrative multi-omics study delineates shared and phenotype-enriched biological programs across the GN spectrum and identifies a prioritized set of candidate targets for future validation and therapeutic development.",
        "42374077": "ID: 42374077\nTitle: Clarifying the molecular mechanisms underlying the lethal in vitro cellular effects and mild organismal phenotype of SOD1 loss.\nAbstract: SOD1 is the superoxide dismutase localized principally to the cytoplasm. It is found in all cell types, is extremely abundant, and highly efficient at converting superoxide (O2\u00b7-) to hydrogen peroxide (H2O2). SOD1 and its homologues in the mitochondrial matrix (SOD2) and extracellular environment (SOD3) are the only enzymes that act directly on superoxide. Surprisingly, Sod1-/- knockout mice exhibit only a mild phenotype. In contrast, Sod1-/- cells cannot survive and multiply in vitro. One possibility for the mild in vivo phenotype is that a subtle genome-wide mechanism of developmental compensation attenuates the phenotype. Conversely, many different mechanisms have been proposed to explain the lethality in vitro and the difficulties of rescuing it with antioxidants. Here, we aim to determine the cause of the severe in vitro phenotype of Sod1-/- cells and whether the mild in vivo phenotype of Sod1-/- mice reflects developmental compensation. We provide evidence that the lethality in vitro is directly due to superoxide toxicity and not to more indirect mechanisms. Furthermore, we created a floxed Sod1 gene to compare acute adult-onset organism-wide removal of the protein with constitutive absence in mice and derived cells. We observed no phenotypic differences between acute and chronic loss of SOD1. We discuss how these observations can be reconciled with the evolutionary conservation of high levels of expression of a broadly expressed, high catalytic rate enzyme.",

This study aimed to assess the effect of cinnamon oil (CO) in broiler diets on growth efficiency, hematological parameters, gene expression, and histological condition. Two hundred sixteen one-day-old broilers were assigned to three treatments in a fully randomized design, with each treatment subdivided into six replicates of 12 chicks. The first treatment is a control group, and the second and third are basic diets with 0.3% and 0.6% CO, respectively. The 0.3% CO group had a higher final body weight, with no significant differences (p \u2265 0.05) in body weight and body weight gain. Birds in this group consumed less FI, leading to a notable improvement in feed conversion rate compared to the control. Additionally, 0.3% CO significantly (p \u2264 0.05) reduced total cholesterol levels without major impacts on most blood parameters, although mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration increased in treated groups. Significant changes were observed in lipase and amylase levels, as well as higher catalase levels and lower malondialdehyde levels. Both 0.3% and 0.6% CO treatments (p \u2264 0.05) increased IGF-1, IL-10, and superoxide dismutase 1 levels, with the 0.6% concentration showing the highest levels. IL-1\u03b2 levels remained low, indicating a specific effect of CO supplementation. Moreover, in the 0.3% CO group, CO supplementation enhanced intestinal absorption by increasing villus height and crypt depth. Adding 0.3% CO to the diet improves feed efficiency, lowers cholesterol, improves blood parameters, lowers inflammation, boosts antioxidant enzymes, and optimally improves intestinal structure, which is beneficial for poultry health and performance.",

Currently, many people and animals are globally facing micronutrient deficiency, especially in lands with poor soils in organic matter and nutrients. Egyptian soil and, consequently, crops were found to be deficient in micronutrients to varying degrees. This study aimed to investigate the potential fertility-enhancing effects of the microalgae Chlorella vulgaris (CV) on male rats fed a salt-deficient diet. Forty-five adult rats (15 rats each) were divided into three groups (G1, G2, and G3). G1 received a normal balanced diet, G2 received a salt-deprived diet (SD), and G3 was supplemented with SD plus Chlorella 1% of the diet (SD + CV). After eight successive weeks of treatment, the animals were fasted overnight, anesthetized, and sacrificed. The collected plasma was analyzed for organ function-related constituents, oxidative biomarkers, and testosterone levels. Epididymal sperms were also examined. Samples of testis were analyzed for quantitative gene expression of GPX4, SOD1, and SPATA6 genes. Additionally, histopathological examination was performed for testis, liver, and kidney samples. The results obtained from the current study revealed that the plasma of the SD group had higher levels of oxidative biomarkers and inflammatory cytokines, elevated urea, creatinine, and uric acid levels, and liver enzymes, and lower testosterone levels than the normal control group. In addition, lower sperm motility and higher abnormality and downregulation of SPATA6 genes and degenerative changes were found in the testes, liver, and kidneys. The administration of (SD + CV) restored these alterations. CV could be used as a supplement to compensate for nutrient or salt deficiency and correct the resultant disorders, especially reproductive affections, in males.",

However, the seminal plasma mechanisms that sustain sperm function under these conditions in goats remain poorly understood. This study aimed to evaluate semen quality and characterize the seminal-plasma proteome of Saanen bucks raised under Indonesia's tropical conditions to identify molecular adaptations associated with fertility resilience. Three healthy bucks (five ejaculates each) were examined using computer-assisted sperm analysis (CASA) for sperm motility, viability, abnormality, membrane and acrosome integrity, and kinematics. Seminal-plasma proteins were separated by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and annotated through Gene Ontology enrichment. While most semen traits and kinematics were comparable among bucks, abnormality and acrosome integrity differed significantly (p < 0.05). A conserved extracellular, vesicle-associated proteome was identified-including BSP1, BSP3, BSP5, ANXA5, ALB, HSPA1A, HSP90AA1, CLU, GPX5, and SOD1-with minor inter-individual variation in LTF, FN1, SPP1, and A2M. Enrichment (FDR < 0.05) highlighted the extracellular region, vesicle, and cytokine-regulatory pathways. This study provides the first proteomic evidence of seminal plasma adaptation to THS in Saanen bucks, revealing a stable core of chaperone, antioxidant, and membrane-coating proteins that safeguard sperm function.

Three groups of mice were studied. Two groups underwent cecal ligation and puncture to induce polymicrobial sepsis. One received vehicle and the other liraglutide via intraperitoneal injection starting 24\u00a0h before the procedure and continuing twice daily until euthanasia. A third group underwent sham surgery and served as control. Forty-eight hours after sepsis induction, mice were euthanized and retinas were isolated for ex vivo assessment of vascular function by videomicroscopy. In addition, reactive oxygen species (ROS) formation and gene expression were evaluated using dihydroethidium staining, quantitative real-time PCR, and immunostaining of NADPH oxidase (NOX)1 and NOX2, respectively. Endothelium-dependent vasodilation to acetylcholine was markedly impaired in retinal arterioles of septic, vehicle-treated mice but was partially preserved in liraglutide-treated septic mice. In contrast, vasodilation to the endothelium-independent vasodilator sodium nitroprusside was similar across all groups. Dihydroethidium staining revealed increased ROS signals in retinal arterioles, the ganglion cell layer, the inner and outer nuclear layers, and the optic nerve of septic, vehicle-treated mice. These increases were attenuated by liraglutide treatment. Furthermore, retinal mRNA expression of NOX1 was significantly upregulated in septic, vehicle-treated mice but remained at control levels in liraglutide-treated septic mice. . In addition, mRNA levels of SOD2, nNOS, and PAI-1 were increased, whereas NOX4, COX-2, and UCP-2 were decreased in septic, vehicle-treated mice. Liraglutide treatment was associated with increased mRNA expression for the antioxidant enzymes SOD1 and SOD3, reduced expression for MCP-1, ICAM-1 and PAI-1 mRNA levels and restoration of UCP-2 mRNA expression. Immunoreactivity for NOX1, but not NOX2, was increased in retinal blood vessels of septic mice. Treatment with liraglutide attenuates endothelial dysfunction, reduces oxidative stress, and suppresses NOX1 upregulation in the retina during polymicrobial sepsis. These findings highlight the preventive and therapeutic potential of GLP-1 receptor agonists for retinal vascular complications associated with sepsis and systemic inflammation.",

Nevertheless, the precise connection between ROS levels and apoptotic markers in thyroid dysfunction remains unclear. To explore the relationship between ROS levels and intrinsic apoptotic (IA) markers in thyroid homogenates derived from hypothyroidism and hyperthyroidism mouse models. Eighteen male Wistar rats, each weighing 240 \u00b1 10 g, were allocated to three groups of six rats. Hypothyroidism and hyperthyroidism were induced over 8 weeks using 0.05% Propylthiouracil (PTU) and 0.0012% Levothyroxine (L-Thy), respectively. T3, T4, and thyroid-stimulating hormone levels were measured, and thyroid size and body weights were recorded. The levels of ROS markers [MDA, glutathione (GSH), SOD-1, CAT, and GPX) and IA markers (Bax, Bcl-2, and caspase-3) were assessed in tissue homogenates. A gradual weight loss was observed in the hyperthyroidism group compared with the control group. The hypothyroid model showed elevated MDA levels and cleaved caspase-3, as well as a higher Bax/Bcl-2 ratio, whereas GSH, SOD-1, CAT, GPX, and Bcl-2 levels were lower than those in the control group (p < 0.05). In contrast, no changes were observed in the hyperthyroid models. Thyroid hormone levels are inversely correlated with ROS and positively correlated with antioxidant levels.

Recently, nanomaterials have been introduced as part of feed additives to enhance the health of birds. This study aimed to evaluate the effects of dietary Nano-Se supplementation on broiler chicken growth performance, serum antioxidant status, and hepatic expression of oxidative stress-related genes. In total, 250 1-day-old Ross 308 broiler chicks were reared for up to 42 days. Birds were randomly assigned to five treatments (n = 50 birds/treatment; 5 replicates of 10 birds each) in a completely randomized design as follows: firsttreatment (T1; basal diet, control), second treatment (T2; basal diet + 0.3 mg/kg organic Se), third treatment (T3; basal diet + 0.3 mg/kg Nano-Se), fourth treatment (T4; basal diet + 0.6 mg/kg Nano-Se), and fifth treatment (T5; basal diet + 0.9 mg/kg Nano-Se). Growth performance was recorded weekly. On day 42, blood samples were collected for biochemical analysis of antioxidant enzymes, including glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC), and Malondialdehyde (MDA). Liver tissue was harvested for quantitative real-time Polymerase chain reaction analysis of glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), catalase (CAT), nuclear factor 2 (Nrf2), and heme oxygenase-1 (HO-1) gene expression. T4 showed a significant improvement in the final weight and feed conversion ratio. A significant increase in serum GPx activity was observed for T4 compared to T1 at 59.6% (125.3 vs.\u00a078.5 U/ml; p < 0.001), respectively. SOD activity and TAC were both increased by 49.1% (42.5 vs.\u00a028.5 U/ml; p < 0.001), and was 46.2% (2.85 vs.\u00a01.95 mM Trolox equivalents, p < 0.001) in T4 compared with T1. Likewise, MDA concentration was decreased in T4 by 44.4% compared with that in T1 (3.25 vs.\u00a05.85 nmol/ml, p < 0.001), respectively. Additionally, hepatic gene expression analysis revealed a significant upregulation of Nrf2 (3.80-fold), HO-1 (4.20-fold), GPX1 (3.45-fold), SOD1 (3.15-fold), and CAT (2.95-fold) in T4 (p < 0.001). In conclusion, dietary supplementation with 0.6 mg/kg of nano-Se effectively enhanced the Nrf2-mediated antioxidant defense system, reduced oxidative stress, and enhanced growth performance in broiler chicken. These findings support the use of nano-Se as a superior alternative to conventional selenium sources in the diet and could improve the productive and physiological aspects of broilers.",

While human sperm freezing is clinically routine, preserving nonhuman primate sperm remains challenging due to species-specific characteristics and low post-thaw viability. This study aims to investigate the proteomic changes in rhesus macaque sperm before and after cryopreservation, focusing on identifying the molecular mechanisms behind cryoinjury. Semen was collected from six sexually mature male rhesus macaques (6-10 years) using rectal electroejaculation. Motility parameters were quantified pre- and postcryopreservation using computer-assisted semen analysis (CASA) with vapor-phase liquid nitrogen protocols. Data-independent acquisition (DIA) quantitative proteomics, combined with LC-MS/MS, was used to profile global protein expression changes. Differential protein analysis was performed using multibioinformatics tools for functional annotation and network modeling. Papanicolaou and acridine orange (AO) staining were used to assess sperm morphology and DNA integrity, while reactive oxygen species (ROS) assay and immunofluorescence were employed to validate the proteomic analysis results. We identified 512 differentially expressed proteins (32 upregulated, 480 downregulated), which are predominantly enriched in pathways related to metabolic reprogramming, oxidative stress response, and protein homeostasis. Immunofluorescence staining further confirmed markedly reduced levels of SOD1, PGK2, PKC\u2011alpha, and phospho\u2011tyrosine in sperm after freeze-thaw cycling. These molecular hubs are associated with sperm motility and functional stability and may be essential for regulating energy metabolism, oxidative balance, and proteotoxicity during cryopreservation-induced stress in rhesus macaque sperm. Cryopreservation induces profound proteomic remodeling in rhesus macaque sperm, mitochondrial electron transport, and metabolic homeostasis. Our findings reveal conserved and species-specific cryoinjury mechanisms, offering molecular targets for optimizing cryopreservation protocols in nonhuman primates to advance reproductive conservation strategies.",

This study examined the acute toxicity by exposing adult zebrafish to three concentrations (1, 5, and 10\u2009mg/L) of ciprofloxacin (CIP) and levonadifloxacin (LND) for 96\u2009h. Behavioral, histological, biochemical, and transcriptional changes were assessed. In the novel tank-dive test, both antibiotics induced concentration- and time-dependent anxiogenic behaviors, such as reduced exploration, decreased total distance traveled, and less time in the upper zone. Histopathological analysis showed progressive tissue damage beginning in the gill epithelium and spreading to the intestine and muscle. Overall, lesion severity increased with higher concentrations and was consistently higher in CIP-exposed fish. Antioxidant enzyme activity exhibited significant changes in superoxide dismutase, catalase, and glutathione peroxidase 1. Early increase in enzyme levels at 48\u2009h coincided with reduced transcription of sod1, cat1, and gpx1a. At 96\u2009h, transcription levels increased while protein levels remained stable. Pathway analysis grouped these genes within interconnected oxidative stress networks rather than cell death pathways. Overall, the results indicate that exposure to both fluoroquinolones for 96\u2009h causes a staged oxidative stress response, along with behavioral disruptions and tissue damage. CIP caused stronger immediate biological effects than LND at the same concentrations, although both antibiotics disturbed organismal homeostasis at sublethal levels. These findings highlight the ecological importance of short-term antibiotic contamination and demonstrate the value of multiple endpoints for detecting early toxic effects in aquatic organisms.",

While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years).

To enhance its therapeutic potential, we developed a vesicular CO-releasing system based on a carbonyl metallosurfactant (PCOL6) and soy phosphatidylcholine (SPC) and evaluated its physicochemical properties, as well as its in silico and in vivo effects on inflammation-induced nociception and muscle impairment in male C57BL/6 mice. The metallosomes exhibited a uniform size distribution, stability upon dilution, and a predominantly single membrane, indicating their suitability for therapeutic applications. Computational simulations revealed that PCOL6 can mix with phospholipids to form stable lamellar structures with thinner and more disordered bilayers than those of pure phospholipid membranes. In vivo experiments showed that acute administration of PCOL6/SPC vesicles inhibited complete Freund's adjuvant (CFA)-induced allodynia faster and longer than tricarbonyldichlororuthenium (II) dimer, Ru2Cl4(CO)6 (CORM-2). Repeated metallosome treatment was also more effective than CORM-2 at reducing allodynia, hyperalgesia, and inflammation-related muscle deficits. Both CO releasers normalized CFA-induced NOD-like receptor protein 3 inflammasome overexpression, increased heme oxygenase 1 (HO-1) and NAD(P)H quinone dehydrogenase 1 expression, and maintained elevated superoxide dismutase 1 levels in paw tissues; notably, HO-1 induction was greater in PCOL6/SPC-treated mice. These findings suggest that PCOL6/SPC metallosomes represent a promising therapeutic strategy for chronic inflammatory pain. Vesicles bearing a CO-releasing metallosurfactant (PCOL6) inhibit inflammatory pain.The analgesic effect of PCOL6/SPC is higher and lasts longer than that of CORM-2.PCOL6/SPC exerts anti-inflammatory and antioxidant effects.",

In this study, the effects of \u03b2CD-modified with dimethylolpropionic acid (Bis-MPA) dendrons (\u03b2CD-m2G and \u03b2CD-m3G) were evaluated in SVGp12 (non-tumor astrocytes) and A172 (glioblastoma) cells. The dendronized systems exhibited low cytotoxicity (>75% viability) even at high concentrations (90\u00a0\u03bcM, p\u00a0<\u00a00.05). Morphological analyses revealed lipid inclusion bodies (LIBs), suggesting that after intracellular uptake, the dendronized containers promote their formation. \u03b2CD-m3G occupies 12% of the cell volume in SVGp12 and 17% in A172 (p\u00a0<\u00a00.05). Ultrastructural evaluation showed increased smooth endoplasmic reticulum (SER), a finding consistent with enhanced lipid metabolism. Importantly, cell differentiation and endoplasmic reticulum stress, evaluated by the expression of Aquaporin-4 and calnexin, were not impaired (p\u00a0>\u00a00.05). A twofold increase in mGlu-5 expression (p\u00a0<\u00a00.001) was observed in both cell lines due primarily to the \u03b2CD-m3G container. Because neither container induces oxidative stress in the SVGp12 cell line, cell proliferation increases from 41% to 48% (p\u00a0<\u00a00.001) due to \u03b2CD-m2G and \u03b2CD-m3G, respectively. These cells also increased Caspase9 expression (p\u00a0<\u00a00.001), suggesting control of proliferation. However, \u03b2CD increased NRF2 expression by 4.3-fold (p\u00a0<\u00a00.0001) and the expression of SOD1, HMOX1, and PRDX1. \u03b2CD increases 1.8-fold-ROS in A172 cells (p\u00a0<\u00a00.001) versus control. 3.5-fold expression of NRF2 was observed in the presence of NAC (p\u00a0<\u00a00.001). These suggest that only \u03b2CD increases NRF2 and ROS as an adaptive response of A172 cells. The incorporation of amphiphilic dendritic groups enables efficient cellular uptake of \u03b2CD-dendronized containers.",

Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200\u202f\u03bcg/mL (carvacrol) and 240\u202f\u03bcg/mL (quercetin) to 17\u202f\u03bcg/mL and 10.9\u202f\u03bcg/mL, respectively (FICI\u202f=\u202f0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by \u223c64.4% (vs. \u223c56.5% for carvacrol and \u223c51.5% for quercetin alone) and inducing apoptosis-like cell death with robust metacaspase activation supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established.",

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.",
        "42390843": "ID: 42390843\nTitle: Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis.\nAbstract: Superoxide dismutase 1 (SOD1), a copper-dependent antioxidant, is essential for redox homeostasis, and its decline drives renal senescence and fibrosis. However, the mechanisms linking profibrotic signaling to SOD1 inhibition remain unclear. Here, we identified a pathological copper-COMMD1-SOD1 axis in which intracellular copper overload paradoxically suppressed SOD1 activity. In kidney tissues from chronic kidney disease (CKD) patients and complementary in vivo and in vitro fibrotic models, we consistently observed a reduction in SOD1 activity accompanied by elevated intracellular copper levels.\u00a0Lowering intracellular copper levels restored SOD1 activity, suppressed reactive oxygen species (ROS) accumulation, and alleviated cell senescence and fibrosis. Mechanistically, pathological copper overload impaired SOD1 homodimerization, the essential final step in its activation. We identified copper metabolism MURR1 domain containing 1 (COMMD1) as a key copper-sensitive mediator of this process. Copper overload acted upstream, simultaneously upregulating COMMD1 expression and enhancing its binding affinity to SOD1. This enhanced COMMD1-SOD1 interaction directly disrupted SOD1 homodimer assembly and enzymatic function. Collectively, these findings redefined the regulatory role of copper in SOD1 activity and uncovered a previously unrecognized mechanism by which pathological copper overload paradoxically suppressed SOD1 activity via COMMD1-dependent disruption of SOD1 homodimerization, providing new insight into the pathophysiology of copper dyshomeostasis-associated diseases.",

While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.",

Furthermore, the formed assemblies act as key players in developing and fostering neurotoxic processes, with distinct mechanisms depending on the stage of the amyloid cascade. Particularly, the oligomer intermediates are now considered as the main drivers of neurotoxicity, thus requiring an early antiaggregant therapeutic intervention to achieve a significant neuroprotective efficacy. Among different strategies, direct interaction at early stages preventing aggregation is quite intricate due to the considered undruggability of misfolded monomers. In this context, a covalent approach targeting specific functional nucleophilic residues within disordered proteins can offer an intriguing opportunity to overcome these weaknesses. Therefore, in this review, we outline covalent modulators of misfolding and aggregation processes reported to date, referring to the major misfolded proteins in the neurodegenerative context (i.e., \u03b2-amyloid, tau, \u03b1-synuclein, and superoxide dismutase 1) to highlight their potential both as valuable pharmacological tools or therapeutic perspectives.",
        "42398690": "ID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.",

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.",

The Ce doping effectively prevented hemin aggregation, facilitated electron transfer, enhanced photocatalytic activity, and created a high adsorption capacity for tetracyclines (TCs). Taking advantage of the photo-sensitivity of TCs, a \"turn-on\" colorimetric sensing platform based on Ce-hemin nanozymes and smartphone-readout was constructed for visual analysis of TCs. This sensor offers a wide detection range and a low limit of detection (0.11\u00a0\u03bcM). The mechanism of the \"turn-on\" colorimetric performance was systematically discussed, which involves the abundant generation of superoxide radical anion (\u00b7O2-) species through photoexcitation of the surface complex between TCs and Ce-hemin. Furthermore, machine learning was employed for the accurate classification and identification of two representative TCs and chloramphenicol. Thus, this work provides an environmentally friendly strategy for the detection of TCs without H2O2, and also broadens the application of photo-responsive nanozymes in colorimetric sensors.",

Published estimates of the penetrance of specific ALS/FTD variants, including the C9orf72 repeat expansion, have varied widely. However, it is now apparent that most pathogenic variants identified in clinical testing exhibit reduced penetrance.

Existing detection methods (e.g., HPLC, GC-MS) rely on sophisticated instruments and complex procedures, limiting their practicality. Colorimetric sensors based on nanozymes offer simplicity and rapidity but often suffer from poor selectivity because of interference from structural isomers (catechol and resorcinol). The development of a high-performance nanozyme with synergistic activity and selective HQ detection remains a critical challenge. A bimetallic nanozyme (Cu-MOF@CoNPs) was engineered via a \"ship-in-a-bottle\" strategy, which successfully confined cobalt nanoparticles (Co NPs) within a porous copper-organic framework (Cu-MOF) scaffold. Characterization (SEM, XRD, FTIR, and XPS) confirmed the successful integration of Co NPs into the Cu-MOF matrix, preserving structural integrity through a pillaring effect while enhancing active site exposure. The composite exhibited superior peroxidase-like activity, with Michaelis constants (Km) of 0.39\u202fmM (TMB) and 0.18 mM\u202f(H2O2), indicating higher substrate affinity than that of natural horseradish peroxidase (HRP). Catalysis was driven by synergistic Cu-Co electron transfer, generating holes (h+) and superoxide radicals (\u2022O2-). A \"signal-off\" colorimetric sensor was constructed on the basis of the HQinduced reduction of oxidized TMB (oxTMB), achieving a linear range of 0.2-12\u202f\u03bcM, a low detection limit of 65\u202fnM, and high selectivity for HQ over structural isomers (catechol and resorcinol) due to steric confinement and favorable redox kinetics, as verified through expanded interference studies. Practical applicability was validated in tap water, lake water, soil extracts, and cosmetic samples, with recoveries of 94-110% and relative standard deviations <3.5%. The Cu-MOF@CoNPs nanozyme-based sensor provides a cost-effective, portable platform for onsite HQ detection in environmental and consumer safety monitoring. Its high sensitivity, selectivity, and stability highlight the potential of hierarchical MOF-confined bimetallic nanozymes as robust tools for reliable phenolic pollutant analysis.",

Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot.",

Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.",

Autopsy tissue donors have provided the first opportunity to study the distribution of intrathecally administered tofersen in human central nervous system tissues. To determine the tissue distribution of tofersen and to provide the first estimates of SOD1 reduction in human somatic motor systems tissues. This was a cross-sectional autopsy tissue case series conducted between 2018 and 2026. Autopsies were performed at 3 US academic medical institutions. Tissue samples from 8 deceased patients who lived with SOD1-ALS, participated in tofersen clinical trials (ClinicalTrials.gov Identifiers NCT02623699 [An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 (Tofersen) in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS)] and NCT03070119 [Long-Term Evaluation of BIIB067 (Tofersen)]) or the Expanded Access Program, and whose families authorized autopsies were eligible for this study. All autopsy tissue donors known at the time of this study were included (none were excluded). Analyses were conducted between August 2020 and January 2026. Participants received multiple intrathecal 20- to 100-mg tofersen doses. Tofersen tissue concentrations were measured using hybridization enzyme-linked immunosorbent assay (ELISA). SOD1 messenger RNA (mRNA) and protein reduction estimates, defined as percentage SOD1 levels in this study's recently treated autopsy tissue donors compared to a cohort of samples from tofersen-naive SOD1-ALS autopsy tissue donors, were measured using quantitative reverse transcription polymerase chain reaction (PCR) and ELISA. Histological localization of tofersen and SOD1 transcripts were studied using immunohistochemistry and in situ hybridization assays. In 8 tofersen-treated autopsy tissue donors (5 male and 3 female donors; age range, 42-66 years), spinal cord and motor cortical tissue tofersen concentrations strongly correlated with predictions based on individual dosing histories and a preclinical pharmacokinetic model. For 3 recently treated autopsy tissue donors, reductions in lumbar spinal cord tissue SOD1 mRNA and protein levels ranged from 45% to 84% despite not having been administered 1 to 2 scheduled doses before autopsy. Residual somatic motor neurons demonstrated tofersen transduction and low SOD1 mRNA probe hybridization. Misfolded SOD1 protein inclusions were detected in residual motor neurons of tofersen-naive SOD1-ALS tissue donor controls and tofersen-treated tissue donors. Meningeal and perivascular lymphocytic immune responses were observed in 5 recently treated tissue donors but were not apparent in tissue donors with remote final tofersen doses. This case series presents the first emerging autopsy tissue data confirming the predicted distribution of tofersen and robust SOD1 protein reduction in human somatic motor systems tissues.",

Historically, testing was routinely offered to those with familial ALS (fALS), but inconsistently to those with sporadic ALS (sALS). We evaluated changes in genetic testing and counseling practices among Canadian ALS physicians over a five-year period spanning pivotal clinical trial results and regulatory approval of tofersen. Members of the Canadian ALS Research Network were surveyed in 2020, 2022, and 2025 about genetic testing practices for symptomatic and asymptomatic individuals, gene panel composition, access to genetic counseling, and perceived drivers of change. Clinics offering genetic testing for sALS increased from 33% of clinics in 2020 and 57% in 2022 to 100% of respondents in 2025. Genetic testing for patients with a family history (fALS) was near-universal across all timepoints.

This study examined the in vitro effects of SN on UVB-induced damage and skin-related cellular responses in human keratinocytes. Cell viability assays, gene expression analysis, luciferase reporter assays, immunoblotting, scratch wound-healing assays, and LC-Q-TOF-MS analysis were conducted. SN showed no significant cytotoxicity in HaCaT or HEK293T cells at concentrations up to 75 \u03bcg/mL. In UVB-irradiated HaCaT cells, SN improved cell viability, suppressed MMP-1 expression, increased HAS-1 expression, and modulated UVB-responsive stress-related markers, including SOD-1, Nrf2, and HO-1. SN also promoted wound closure in keratinocytes and was associated with changes in NF-\u03baB-, AP-1-, CREB-, and MAPK-related signaling responses under the tested conditions. LC-Q-TOF-MS analysis tentatively identified several candidate constituents, including pectolinarin and aloeresin-related compounds. Collectively, these findings suggest that SN exerts multiple beneficial in vitro effects in keratinocyte-based assays, warranting further mechanistic investigation and validation in advanced experimental models.",

However, direct evidence linking oxidative stress to impaired hepatic function in human biliary atresia (BA) remains limited. To address this, we performed bulk RNA sequencing to investigate (1) alterations in hepatic oxidative stress and antioxidant defense mechanisms and (2) transcriptomic changes associated with impaired hepatic function in BA. Total RNA was extracted from liver samples of patients with BA and non-BA cholestasis. Bulk RNA sequencing and transcriptomic analyses were performed, focusing on redox-related pathways and genes linked to hepatic function. Dual oxidases 1 and 2 were significantly upregulated in BA. In contrast, key ROS-metabolizing enzymes such as catalase, glutathione synthetase, and superoxide dismutase 1 and 2 were downregulated, indicating redox imbalance in BA livers. Excessive ROS can lead to the denaturation of cellular proteins and damage to organelles, which are normally degraded via autophagy and proteasomes. However, both autophagy and proteasome functions were impaired in BA, contributing to sustained inflammation and further ROS production. Transcriptomic analyses also revealed repression of core liver transcription and splicing factors, indicating injury-associated alterations in hepatic transcription programs. BA is characterized by a redox imbalance and dysfunctional protein clearance, forming a vicious cycle of ROS accumulation and inflammation. These changes likely contribute to liver fibrosis and the progressive loss of hepatic function in BA.",

Here, we report hydroxyl-functionalized three-dimensional covalent organic framework (COF) membranes that regulate proton-coupled electron transfer within ordered nanochannels. Phenolic hydroxyl groups are precisely embedded in the membrane pores as internal proton reservoirs, while the continuous COF framework provides pathways for photogenerated electron transport. By tuning hydroxyl density, the dihydroxylated COF-2OH membrane establishes an optimal proton-management microenvironment, promoting O2 adsorption, charge separation, superoxide/*OOH intermediate formation, and dynamic proton recycling. Under one-sun irradiation in pure water and ambient air, COF-2OH achieves an H2O2 production rate of 21.79\u00a0mmol g- 1 h- 1 without sacrificial agents or cocatalysts, greatly outperforming the corresponding powder catalyst. Mechanistic experiments and simulations reveal that membrane confinement and hydroxyl-mediated proton buffering jointly synchronize proton and electron fluxes during continuous photocatalysis. The free-standing membrane can also be integrated into a tubular Al2O3-supported reactor for in situ H2O2-driven photo-Fenton degradation of organic pollutants. This work establishes proton-managing COF membranes as programmable reaction interfaces for efficient solar H2O2 production and integrated water treatment.",

Photocatalytic NH3 oxidation over TiO2 is a promising strategy for air purification but is hindered by poor selectivity, often leading to the formation of toxic NOx byproducts due to the complex reaction network involving multiple competing pathways and intermediates. This study addresses this selectivity issue by designing a modified TiO2 photocatalyst through a synergistic defect-dopant engineering approach. Through controlled doping and defect engineering, we demonstrate that N doping and OVs distinctly modulate the reaction mechanism and products' selectivity. Nitrogen doping thermodynamically promotes N2 formation by stabilizing NH2 intermediates and facilitating their selective coupling with NO, whereas OVs kinetically facilitate NH3 and O2 dissociation, promoting superoxide-mediated oxidation, leading to overoxidized products such as NOx and nitrate/nitrite HNOx- species. An optimal N-doped TiO2 catalyst achieves 87% NH3 conversion with 80% N2 selectivity and minimal NOx emission (\u223c5 ppm), while exhibiting excellent stability over multiple cycles. This work elucidates a defect-dopant strategy that optimizes kinetic and thermodynamic aspects of NH3 oxidation, providing a design principle for selective photocatalytic nitrogen management toward sustainable air purification.",

We cloned six immune-related cytokines from Amur tigers (Panthera tigris altaica), with sequence analysis revealing >90% identity across Felidae. Among all tested cytokines, IL-15 demonstrated superior and sustained lymphocyte-stimulatory activity at 200\u202fng/mL. To investigate antiviral potential, F81\u202fcells were pretreated with IL-15 and challenged with feline panleukopenia virus (FPV). Mechanistic studies revealed that IL-15 attenuated virus-induced apoptosis by modulating key regulatory proteins: downregulating pro-apoptotic factors (Bax, Caspase3/9, p53, Cytc) while upregulating anti-apoptotic Bcl-2. Additionally, IL-15 preserved mitochondrial integrity by maintaining membrane potential, enhancing fusion proteins (MFN1/MFN2), and suppressing fission protein Drp1. IL-15 also strengthened cellular antioxidant defenses through increased SOD1/SOD2 expression, significantly reducing reactive oxygen species (ROS) accumulation. These protective effects persisted for 48\u202fh post-infection, demonstrating sustained cytoprotective effects. These findings reveal species-specific IL-15-mediated antiviral mechanisms within the Felidae family and provide comparative insights into how immune defenses are optimized in species with constrained evolutionary history, with implications for understanding carnivore immune evolution and conservation medicine.",

The C9orf72 protein forms a complex with SMCR8 and WDR41 (CSW), which functions as a GTPase-activating protein (GAP) regulating ARF1 and RAB small GTPases. While these findings implicated ARF1-GAP dysregulation in ALS/FTD and supported ARF1 suppression as potential intervention, small molecules that modulate ARF1-CSW interactions are lacking. In this study, we demonstrated upregulation of tyrosine-phosphorylated (Tyr-782) ASAP1 (also known as AMAP1, DDEF1, or Centaurin \u03b24), an ARF-GAP, in human motor cortex of both sporadic ALS and ALS with C9orf72 mutations. Ectopic C9orf72 expression partially mimicked the effects of a known ARF1 inhibitor brefeldin A to disperse Golgi apparatus. Computer-aided rational drug design with high-throughput in-silico screening identified MCULE-5095997944 (Named as SCC944) as a ARF1-CSW modulator. SCC944 binds directly to ARF1 and reduced GTP-bound ARF1 levels upon ARF1 activation. SCC944 demonstrated brefeldin A-like ARF1-dependent alteration of organelle organization including Golgi, microtubules, and mitochondria, but also a protein trafficking pattern that is distinct from brefeldin A mechanism. These studies identified the first small molecule targeting ARF1-CSW interaction and further support ARF1 modulation as a potential therapeutic approach for ALS/FTD.",

Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.",

Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the \u03b11 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.",

However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI. Male Wistar rats were divided into four experimental groups: Sham, Infarct, Sham+MitoQ, and Infarct+MitoQ. MitoQ was administered orally (8\u2009mg/kg/dia) for 7\u2009days. Hemodynamic parameters, infarct area, papillary muscle contractility, cardiomyocyte mechanics, Ca2+ transients, and total and mitochondrial superoxide (DHE and MitoSOX) were assessed. After 7\u2009days of MI, rats exhibited impaired contractility, altered inotropic response to extracellular Ca2+, cardiomyocyte hypertrophy, and increased total and ROSm. MitoQ prevented body weight loss and significantly improved hemodynamic parameters compared to the Infarct group. In papillary muscles, MitoQ restored basal isometric force and the inotropic response to extracellular Ca2+. In cardiomyocytes, it attenuated hypertrophy, preserved shortening, and reduced ([Ca2+]i) transient amplitude. MitoQ significantly decreased total and mitochondrial O2\u2022- production. It selectively reduced NOX1 expression under simulated conditions but did not significantly affect NOX2, SOD1, or catalase expression in the context of MI. MitoQ prevented contractile dysfunction, suggesting that mitochondrial oxidative stress plays a decisive role in myocardial dysfunction during the acute phase of MI. Targeting antioxidant therapy to the mitochondria represents a promising strategy for preventing post-infarction heart failure and opens new perspectives for the development of more effective interventions in the treatment of cardiovascular diseases.",

The molecular mechanisms underlying the responses of Trichoderma to combined abiotic stresses remain insufficiently understood. In this study, the stress-tolerant Trichoderma viride strain Tv-1511 was analyzed using RNA sequencing to characterize its transcriptomic responses under PEG-simulated drought stress, and the resulting data were integrated with previously generated transcriptomic datasets from high-temperature (42\u00a0\u00b0C, 24\u00a0h) and salinity (300 mmol/L NaCl, 72\u00a0h) treatments. Under 50% Polyethylene glycol (PEG)-simulated drought, 4510 differentially expressed genes were identified and enriched in secondary metabolite biosynthesis and \u03b2-lactam antibiotic synthesis based on Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. Integrating these drought stress data with the high-temperature and salinity datasets revealed 36 commonly upregulated and 29 commonly downregulated genes across triple stresses, primarily involved in redox processes and secondary metabolite synthesis. RT-qPCR validation indicated that Trichoderma mounts a synergistic response to multiple stresses by activating genes like MET17, ALDH (aminoglycoside synthesis), and FeSOD, Cu/ZnSOD, GCLC, GLO1, GST. These findings elucidate key transcriptomic mechanisms underlying Trichoderma responses to single and combined abiotic stresses and provide a theoretical foundation for the targeted improvement of stress-tolerant strains to enhance their agricultural and industrial utility.",

However, enhancing oxygen adsorption and activation as well as substrate adsorption capability in aqueous-phase to optimize catalytic oxidation performance remains a significant challenge. Herein, a Pt/Zr-CeO2 catalyst was prepared via a single-atom doping strategy. Characterization revealed that Zr atoms were successfully incorporated into the CeO2 lattice, markedly increasing the oxygen vacancy concentration and enhancing the surface Lewis acidity. This dual modulation not only creates abundant sites for molecular oxygen activation but also facilitates efficient adsorption of aldehyde and hydroxyl groups of glucose. Mechanistic studies indicate that the enhanced oxygen vacancies promote the generation of superoxide radicals (O2-). These radicals are further converted into peroxide species (O22-) under aqueous conditions and induce the formation of hydroxyl radicals (OH), which synergistically activate CH and OH bonds of glucose. The synergy between oxygen vacancies and Lewis acid sites enables the highly selective production of glucaric acid under mild conditions. Meanwhile, the catalyst exhibits excellent stability during cycling tests, with no obvious deactivation. This study demonstrates that single-atom Zr doping is an effective strategy for modulating the defect chemistry and surface acidity of CeO2-based catalysts, providing new insights into the design of high-performance oxidation catalysts for biomass valorization.",

In this study, the effects of salt stress (150 mM NaCl), PEG-induced drought stress (4% PEG-8000), and their combined application on the in vitro responses of dragon fruit (Hylocereus undatus) were evaluated at morphophysiological, molecular, and machine learning levels. The selected NaCl and PEG concentrations were used to impose moderate-to-severe salinity and osmotic stress conditions previously reported to affect pitaya growth and physiology. Cladode explants were exposed to stress treatments for 14 days, after which visual stress score, lateral shoot number, stem length, root length, stem diameter, fresh weight, dry weight, root number, and SPAD value were measured. In addition, the expression levels of five stress-responsive genes (HuERF1, HuTZF3, Cu/Zn-SOD, CAT, and NCED) were analyzed using RT-qPCR. Salt stress and, more prominently, the combined salt-drought treatment markedly impaired plant growth and physiological performance. Compared with the control, the combined treatment reduced root length by approximately 87%, fresh weight by 67%, root number by 54%, and SPAD value by 46%, indicating severe inhibition of root development, biomass accumulation, and chlorophyll-related performance. Gene expression analysis revealed strong induction of HuERF1 and Cu/Zn-SOD under salt-containing treatments, suggesting activation of stress-signaling and antioxidant defense responses, whereas NCED showed the highest upregulation under PEG-induced osmotic stress and combined stress, indicating the involvement of ABA-mediated osmotic adjustment. In contrast, CAT expression remained relatively stable across treatments. Morphological data were further analyzed using a Random Forest classifier, which distinguished stress treatments with an overall accuracy of approximately 73%. Feature importance analysis identified SPAD value, visual stress score, lateral shoot number, root number, and fresh weight as the most informative morphophysiological variables for treatment discrimination. Overall, these results demonstrate that salinity and drought, especially in combination, substantially affect growth performance and stress-responsive gene regulation in H. undatus, and highlight the potential of machine learning for identifying phenotypic signatures associated with abiotic stress responses.",

However, studies investigating the toxic effects of Cd on crucian carp (Carassius auratus) are relatively few. This study aimed to evaluate the toxic effects of Cd by assessing hematological parameters, antioxidant responses, and the expression of stress-related genes in C.\u00a0auratus exposed to waterborne Cd. A total of 180 healthy C.\u00a0auratus (19.43 \u00b1\u00a01.5 cm and 170.00 \u00b1\u00a03.04 g) were exposed to Cd at concentrations of 0, 2, and 4 mg/L for 8 weeks, with three replicates per treatment. The exposure to Cd resulted in significant reductions in red blood cell (RBC) count, hemoglobin (Hb) concentration, and hematocrit (Hct) values. Moreover, the levels of total superoxide dismutase (T-SOD), catalase (CAT), and glutathione peroxidase (GPx) in the liver also decreased significantly, whereas malondialdehyde (MDA) content was increased significantly. The expression levels of CAT, copper (Cu)/zinc (Zn)-superoxide dismutase (Cu/Zn-SOD), heat shock protein 70 (HSP70), heat shock protein 90 (HSP90), and metallothionein (MT2) genes were significantly upregulated. Overall, Cd exposure adversely affected the hematological parameters, induced oxidative stress, and altered the expression levels of stress-related genes.

However, the role of NOP56 in mammalian neurodevelopment and disease remains poorly defined. We investigated NOP56 pathobiology using both in vitro induced pluripotent stem cell-derived neurons and in vivo NOP56 knockout mouse models. NOP56 expression significantly decreased both in the spinocerebellar ataxia type 36 patients induced pluripotent cells and induced pluripotent cell-derived neurons, which suggests the possibility that the NOP56 loss of function is involved in the spinocerebellar ataxia type 36 phenotype. Therefore, we generated and validated the NOP56 knockout mouse phenotype. Homozygous NOP56 deletion resulted in total embryonic lethality; no NOP56-/- progeny was viable at birth. Heterozygous knockouts showed clasping at 8 months of age and had a larger body size with aging, although there was no significant difference in survival between heterozygous and wild type. Heterozygous knockout mice showed deterioration in rotarod performance and a decrease in exploration behavior. Immunohistochemical analysis of the heterozygous knockouts revealed widespread, significant central nervous system abnormalities, particularly cerebellar degeneration, accompanied by motor cortex and spinal cord disturbances. Widespread ubiquitin-positive inclusions were detected in the cerebellum, motor cortex, and anterior spinal cord of the heterozygous knockout mice at the 12-month age, and it was positive from the 6-month age in the cerebellum. Colocalizations of TDP-43 and ubiquitin were observed in the motor cortex, spinal cord, and cerebellum. Along with findings from previous reports showing early downregulation of NOP56 in SOD1 G93A transgenic mice, this finding indicates that NOP56 might be involved in a wide range of motor neuron diseases. The pathological characteristics of the NOP56 heterozygous knockouts are like those of a patient with spinocerebellar ataxia type 36. Results reveal that NOP56 is indispensable for mammalian embryogenesis and central nervous system maintenance, and that its reduction contributes to molecular pathology in spinocerebellar ataxia type 36. These findings uncover a convergent neurodegenerative mechanism and identify NOP56 as a potential therapeutic target.Clinical trial registrationThis study was registered with the Japan Clinical Trials Registry (http//umin.ac.jp/ctr/index/htm), under the number UMIN000047097.",

In genetic counseling, children of mutation carriers are often told that they have a 50% risk of carrying the mutation, but this figure does not take into account the fact that penetrance is age-related, with a unimodal distribution of disease onset around 58 years of age. Using a Bayesian approach, we developed a theory to calculate the probability of carrying the mutation for asymptomatic relatives (children/siblings and grandchildren/niblings) as well as the probability of developing ALS/FDT within a given time frame, based on their age. Using published data on age-related penetrance, we then calculated these probabilities and developed an online simulator that makes it easy to calculate them on a case-by-case basis. The conditional probabilities obtained can be very different from Mendelian values. For example, a 70-year-old asymptomatic child born to a carrier has approximately a 6% risk of being a carrier, which is far from 50%. For grandchildren, taking into account both their age and that of their parents also leads to figures that are much lower than those obtained if only their age were considered. For consultands, the decision to undergo testing is based in part on risk estimates. In this regard, the refined estimates and simulator we propose may prove to be valuable tools for genetic counseling for families affected by ALS/FTD linked to the C9orf72RE mutation. In addition, the formulas used in this study could also be used to calculate risk estimates for other diseases caused by autosomal dominant mutations with age-dependent penetrance.",

Current therapeutic strategies are often unsatisfactory due to limited efficacy or adverse effects. This study investigated the protective effects and potential molecular mechanisms of Ganoderma lucidum (GL) polysaccharides and triterpenoids against testicular injury in high-fat diet-induced obese male rats. After 12-week GL intervention, reproductive function in obese male rats showed improvement: GL increased litter size, improved sperm motility, reduced sperm DNA fragmentation, and restored serum testosterone, inhibin B, and leptin levels. It also alleviated testicular histopathological damage, downregulated PPT1, and maintained vimentin expression. Notably, GL facilitated delayed fertility recovery and showed a trend toward improved cumulative reproductive success, although fixed-time pregnancy rates were not significantly changed. Mechanistically, GL is associated with enhanced Nrf2 pathway activity, increased SOD1, HO-1, NQO1, and GPX4 levels, and decreased MDA and ROS accumulation, thereby attenuating oxidative stress. It preserved mitochondrial integrity, suppressed germ cell apoptosis (downregulating Bax and caspase-3, upregulating Bcl-2), and promoted cell proliferation. These findings indicate that GL polysaccharides and triterpenoids effectively ameliorate obesity-induced testicular dysfunction, and these beneficial effects are associated with Nrf2-mediated antioxidant responses, mitochondrial homeostasis, apoptosis regulation, and hormonal balance. GL may serve as a promising candidate for obesity-related male infertility.",

This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65\u2009years, the mean age at diagnosis was 53\u2009years, and the mortality occurred around 59\u2009years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOE\u03b54, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD.

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.",

Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.",

The polyphenolic compound resveratrol, known for its antioxidant properties, has been widely studied for its potential anti-aging effects. In this study, we investigated the age-dependent effects of resveratrol in Caenorhabditis elegans (C. elegans). Treatment with resveratrol for four consecutive days in young worms (adulthood day 1-4) significantly enhanced lifespan, healthspan, and reduced reactive oxygen species (ROS) generation. In contrast, the same treatment in middle-aged worms (adulthood day 8-11) unexpectedly impaired these phenotypes. Genetic experiments using mutant strains and RNA interference revealed that the gerosuppressor daf-16 and its downstream antioxidant sod-3 mediate these age-specific effects, as deletion of daf-16 or silencing of sod-3 eliminated the age-dependent opposing responses. Transcriptomic analysis identified distinct gene expression patterns between young and middle-aged worms, with the daf-16-regulated gene dod-6 being up-regulated in young worms but down-regulated in middle-aged worms. Silencing dod-6 abolished the age-dependent opposing effects on lifespan, healthspan, and ROS generation. Further studies confirmed that daf-16 regulates sod-3 through dod-6. Then, the divergent effects of resveratrol were validated in human fibroblast BJ cells: resveratrol reduced \u03b2-galactosidase staining and pro-inflammatory cytokine expression in normal cells but exacerbated these markers in D-galactose-induced senescent cells. Together, these findings demonstrate that resveratrol exerts anti-aging effects in young organisms but promotes aging in middle-aged organisms, likely through differential regulation of the daf-16/dod-6/sod-3 axis. This study highlights the importance of understanding age-related drug susceptibility to develop safer and more effective anti-aging interventions.",

However, the extent to which microbial indicators of dysbiosis covary with host oxidative stress and epithelial apoptotic responses during pregnancy remains unclear. In this analytical cross-sectional study, 220 pregnant women were screened at a referral gynecology clinic in Faisalabad, Pakistan; 168 met the eligibility criteria and had concordant modified Amsel and Nugent classifications (56 BV-positive, 112 BV-negative). Cervicovaginal secretions, vaginal swabs, and serum were analyzed for microbial, oxidative stress, and host-response markers. Epithelial-enriched cervicovaginal specimens passing predefined quality criteria (n\u202f=\u202f142) were used for apoptosis-related gene expression and caspase-3/7 activity assays. Targeted microbial quantification focused on Lactobacillus and Acinetobacter spp. Associations between bacterial burden and host markers were evaluated using correlation and regression analyses with the Benjamini-Hochberg false-discovery-rate correction, where applicable. BV-positive participants exhibited a lower Lactobacillus spp. burden and a higher Acinetobacter spp., burden than BV-negative controls. They also showed higher cervicovaginal malondialdehyde and H2O2 concentrations and lower superoxide dismutase and catalase activities (all FDR-adjusted q\u202f<\u202f10-13). Epithelial-enriched specimens from BV-positive participants demonstrated a higher BAX/BCL2 ratio, increased caspase-3/7 activity, increased expression of BAX, CASP9, CASP3, SOD2, and HMOX1, and reduced BCL2 expression. Higher Acinetobacter spp. burden covaried with greater local oxidative stress and increased epithelial apoptosis-associated signaling, although these associations were attenuated after adjustment for BV status. BV in pregnancy was associated with concurrent differences in cervicovaginal microbial indicators, oxidative stress, and epithelial apoptosis-related responses, supporting an integrated host-microbe response at the cervicovaginal interface. These findings provide a foundation for future longitudinal and mechanistic studies investigating host-microbe interactions in pregnancy-associated BV.",

Ficus deltoidea (FD), a medicinal plant rich in flavonoids vitexin and isovitexin, possesses potent antioxidant and anti-inflammatory properties, yet its neuroprotective efficacy in AD remains incompletely characterized. This study investigated the protective effects of FD in a D-galactose- and aluminum chloride (AlCl3)-induced oxidative stress-driven AD-like rat model using behavioral, histological, ultrastructural, and biochemical approaches. Fifty-four male Wistar rats were assigned to six groups: control, AD-like model, donepezil (1\u00a0mg/kg), and FD-treated groups (50, 100, and 200\u00a0mg/kg) for 10\u00a0weeks. Anxiety-like behavior and spatial working memory were assessed using the elevated plus maze (EPM) and T-maze tests, respectively. Hippocampal neuronal integrity was evaluated by hematoxylin and eosin (H&E) staining and transmission electron microscopy (TEM), while oxidative stress biomarkers (MDA, CAT, T-SOD, CuZn-SOD, and HO-1) were quantified using ELISA. FD treatment, particularly at 200\u00a0mg/kg, significantly improved spatial working memory and normalized anxiety-related behavior, with treatment responses approaching those observed in the donepezil-treated group. Histological analyses revealed preservation of pyramidal neurons across CA1, CA2, CA3, and dentate gyrus subregions, while ultrastructural studies demonstrated marked protection of mitochondrial integrity, myelin sheath organization, and smooth endoplasmic reticulum morphology. Biochemically, FD significantly reduced lipid peroxidation and enhanced endogenous antioxidant defenses. In conclusion, FD exerted significant neuroprotective effects characterized by preservation of hippocampal structure, maintenance of neuronal ultrastructure, and restoration of redox homeostasis in an oxidative stress-driven AD-like model. These findings demonstrate that FD mitigates oxidative stress-associated neuronal injury and cognitive impairment in a D-galactose and AlCl3-induced AD-like rat model, supporting its potential as a phytotherapeutic candidate for oxidative stress-related neurodegeneration. However, further studies are required to determine its effects on canonical Alzheimer's disease pathologies, including amyloid and tau abnormalities.",

This work studies the metabolic effects of elevated phosphate on muscle. C2C12 cells were differentiated in the absence or presence of 10 mM \u03b2-glycerophosphate (BGP), an exogenous phosphate donor. In addition, quadriceps muscles from four experimental groups of male C57BL/6J mice were analyzed: young (5 months) and old (24 months) fed with standard diet; old mice fed with hypophosphatemic diet or supplemented with the phosphate binder Velphoro\u00ae, for the last three months of life. Mice were stratified according to sarcopenia degree based on muscle mass, strength and physical performance. Protein levels were determined by immunoblotting and mRNA expression by RT-qPCR. ATP levels were measured by luminescence and L-lactate production, citrate synthase and cytochrome c oxidase activities by colorimetric assays. Mitochondrial content, membrane potential and reactive oxygen species (ROS) were determined by fluorescence assay. BGP-treated cells showed increased glucose transporter 1 (GLUT1) and decreased NADH Dehydrogenase (CI-NDUFB8) protein expression, elevated hexokinase II (HK2), phosphoglycerate kinase 1 (PGK1) and lactate dehydrogenase A (LDHA) mRNA levels, reduced ATP levels, increased lactate production, and decreased mitochondrial enzyme activities. Moreover, BGP increased ROS, diminished mitochondrial membrane potential, and altered fusion-fission dynamics and mitophagy. In aged quadriceps, oxidative phosphorylation (OXPHOS) subunits and superoxide dismutase 2 (SOD2) expression were reduced. The hypophosphatemic diet improved all parameters, whereas Velphoro\u00ae selectively increased Mitochondrial cytochrome C oxidase subunit 1 (CIV-MTCO1) expression. Several altered mitochondrial markers are associated with sarcopenia degree. Altogether, hyperphosphatemia induces metabolic changes that scale with the sarcopenic degree. Our findings show a relevant association between hyperphosphatemia and mitochondrial dysfunction, and they support the potential benefit of phosphate reduction as a strategy to prevent or mitigate sarcopenia.",
        "42449957": "ID: 42449957\nTitle: Molecular Mechanisms of Photobiomodulation in Retinal Diseases: Cytochrome c Oxidase, Mitochondrial Bioenergetics and Cytoprotective Signalling.\nAbstract: Photobiomodulation (PBM) is a non-invasive therapeutic strategy that uses red and near-infrared (NIR) light in the 590-950 nm range to modulate the cellular and molecular pathways involved in retinal homeostasis. At the molecular level, PBM acts primarily through photon absorption by cytochrome c oxidase (CcO, complex IV of the mitochondrial electron transport chain), whose four metal centres-two copper (CuA and CuB) and two heme groups (heme a and heme a3)-absorb light across approximately 600-1000 nm. Photon capture promotes photodissociation of inhibitory nitric oxide (NO) from the binuclear CuB-heme a3 centre, accelerates electron transfer, restores the proton-motive force and increases ATP synthesis. These primary events trigger a coordinated molecular programme that includes (i) transient mitochondrial reactive oxygen species (ROS) bursts that activate the Nrf2/Keap1/ARE axis and upregulate phase II antioxidant enzymes (HO-1, NQO1, GCLC, SOD2, catalase, GPx); (ii) calcium- and cAMP-dependent secondary signalling that converges on PI3K/Akt, MAPK/ERK, AMPK and mTOR pathways; (iii) suppression of NF-\u03baB-driven cytokine production (TNF-\u03b1, IL-1\u03b2, IL-6) and of NLRP3 inflammasome activation; (iv) downregulation of the HIF-1\u03b1/VEGF axis, particularly at 590 nm; (v) anti-apoptotic remodelling of the Bcl-2/Bax ratio with reduced cytochrome c release and caspase-3/9 activation; and (vi) PGC-1\u03b1/TFAM/NRF1-driven mitochondrial biogenesis, alongside restoration of fission/fusion homeostasis (Drp1, Mfn1/2, Opa1) and PINK1/Parkin-mediated mitophagy. Wavelength specificity has a defined molecular basis: 590 nm modulates VEGF signalling and RPE pump activity, 660 nm interacts with the CuB centre and enhances O2 binding at CcO, and 850 nm is absorbed by CuA and supports electron entry into complex IV. A second molecular axis is the bidirectional crosstalk between PBM and the circadian system: mitochondrial respiration, ATP turnover and CcO activity oscillate over the 24 h cycle under the control of the BMAL1/CLOCK and PER/CRY core machinery, the NAD+/SIRT1-SIRT3 axis and REV-ERB\u03b1. Preliminary preclinical and human observations suggest that NIR-induced bioenergetic and functional gains may be coupled to this rhythm, with greater benefit reported when light is delivered in the morning window (\u224808:00-11:00); this time dependence should be regarded as an emerging hypothesis rather than an established clinical principle. The clinical evidence is unevenly developed across indications. It is most robust for non-exudative age-related macular degeneration, where multiwavelength PBM (590/660/850 nm; Valeda Light Delivery System) has shown disease-modifying potential in randomized controlled trials (LIGHTSITE I-III and the LIGHTSITE IIIB extension), with sustained BCVA gains and reduced incidence of geographic atrophy over 24 months and beyond. Evidence for retinitis pigmentosa, central serous chorioretinopathy and, with red-light monotherapy, childhood myopia is at present limited to small or short-term studies and remains preliminary. This narrative review synthesizes the molecular machinery engaged by PBM, integrates clinical findings across retinal diseases and discusses how chronotherapeutic delivery of light, aligned with the molecular clock, may further optimize therapeutic efficacy.",
        "42450113": "ID: 42450113\nTitle: Serum Copper-to-Zinc Ratio and Oxidative Stress Are Associated with Anemia in Older Adults with Cardiovascular-Kidney-Metabolic Syndrome.\nAbstract: Chronic oxidative stress is a molecular hallmark of cardiovascular-kidney-metabolic (CKM) syndrome, yet its contribution to CKM-associated anemia beyond erythropoietin deficiency and iron restriction is poorly characterized. The serum copper-to-zinc (Cu/Zn) ratio reflects impaired Cu/Zn-SOD1 antioxidant capacity and inflammatory trace-element imbalance, but its relationships with circulating redox biomarkers and its hematological relevance in CKM syndrome has never been explored in a community-dwelling cohort of older adults. We analyzed 2391 NHANES 2011-2016 participants \u2265 50 years of age with CKM stage I-IV. To explore whether the serum Cu/Zn ratio was associated with oxidative stress and immunomodulatory biomarkers as well as with the odds of anemia, we used survey-weighted Spearman correlations, linear regression (outcome: hemoglobin), and logistic regression (outcome: anemia); multivariate models were adjusted for a panel of antioxidant or immunomodulatory biomarkers (selenium, vitamin D), pro-oxidant biomarkers (lead, cadmium, cotinine, uric acid), red cell distribution width (RDW) as a composite biomarker of erythrocyte stress, neutrophil-to-lymphocyte ratio (NLR), CKM stage, and comorbidities. The molecular targets of the nine biomarkers were mapped onto a protein-protein interaction network using the STRING database v12.0 to contextualize regression findings within a systems biology framework. Anemia was present in 205 participants (8.6%). The Cu/Zn ratio was inversely correlated with the antioxidant marker selenium (r = -0.19; p < 0.001) and positively correlated with the pro-oxidant markers RDW (r = +0.21; p < 0.001) and cadmium (r = +0.10; p < 0.001), consistent with its role as a hub within the CKM redox network. In fully adjusted models, a higher Cu/Zn ratio was independently associated with prevalent anemia (OR = 2.94; 95% CI: 1.61-5.37) and lower hemoglobin (\u03b2 = -0.55 g/dL); among included biomarkers, selenium and cadmium were independently protective (OR = 0.76 per 10 \u00b5g/L and 0.23 per \u00b5g/dL, respectively), and RDW and uric acid were independently harmful (OR = 2.20 per 1% and 1.33 per mg/dL, respectively). The Cu/Zn ratio correlated with both antioxidant depletion and pro-oxidant accumulation in CKM syndrome and was independently associated with anemia within this oxidative network. Together with selenium, cadmium, RDW, and uric acid, it defines an oxidative stress-driven hematological pathway that may contribute to the development and progression of anemia in patients with CKM syndrome.",

Microvesicles (MV-enriched fraction), a subtype of extracellular vesicles, and the stress-responsive antioxidant protein Sestrin2 (SESN2) have emerged as important contributors to these processes. This study investigated the role of the MV-enriched fraction in endothelial cell communication under diabetic conditions, with a particular focus on oxidative stress signaling. To model diabetic injury, EA.hy926 endothelial cells were treated with methylglyoxal (MGO), and the resulting MV-enriched fraction was isolated and then applied to two recipient models: na\u00efve endothelial cells and SESN2 knockdown (KD) cells. Protein expression of key antioxidant markers, including endothelial nitric oxide synthase (eNOS), was assessed by Western blot. Nitric oxide (NO) bioavailability was quantified via nitrite measurement using 2,3-diaminonaphthalene (DAN), while mitochondrial and cytosolic ROS levels were evaluated using MitoSOX and dihydroethidium (DHE), respectively. Results demonstrated that the MV-enriched fraction derived from diabetic conditions triggers a complex antioxidant response in healthy endothelial cells, characterized by upregulation of SESN2, superoxide dismutase 1 (SOD1), and heme oxygenase-1 (HO-1). This suggests a compensatory mechanism that mitigates oxidative stress. Notably, SESN2 KD cells exhibited increased ROS production and reduced NO levels upon MV treatment, underscoring the essential role of SESN2 in maintaining redox homeostasis. Overall, this study highlights the dual role of the MV-enriched fraction as a mediator of both protective and detrimental redox signaling in diabetic endothelial dysfunction and suggests potential therapeutic targets for managing diabetic vascular complications.",

However, the global transcriptomic landscape underlying stress-induced hepatic injury remains incompletely understood. In this study, we employed a methionine-choline-deficient (MCD) diet-induced murine model to characterize the phenotypic and transcriptomic alterations associated with liver injury. Male C57BL/6J mice were fed either a control or MCD diet, and hepatotoxicity was assessed by survival analysis, body and liver weight measurements, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, histopathological examination, RNA sequencing, quantitative real-time PCR (qRT-PCR), and tumor necrosis factor-alpha (TNF-\u03b1) enzyme-linked immunosorbent assay (ELISA). MCD feeding markedly reduced survival and body weight while inducing hepatomegaly and significant elevations in serum ALT and AST, indicating severe hepatocellular injury. Histopathological analysis demonstrated hepatic steatosis, hepatocellular ballooning, and lobular inflammation without histological evidence of fibrosis. Transcriptomic profiling revealed extensive gene expression remodeling, characterized by activation of inflammatory pathways, enrichment of MAPK-related signaling, dysregulation of lipid metabolism, suppression of antioxidant defense systems, impairment of cytochrome P450-mediated detoxification, and upregulation of apoptosis-associated genes. qRT-PCR further validated the differential expression of representative genes involved in inflammatory signaling (Tlr4, Nfkb1, Nlrp3, and Casp1), MAPK signaling (Fos), xenobiotic metabolism (Cyp4f18), lipid metabolism (Apoa4 and Lpl), extracellular matrix remodeling (Mmp12), and oxidative stress responses (Sod1 and Gstp1). In addition, elevated serum TNF-\u03b1 levels provided protein-level evidence supporting activation of the TLR4/NF-\u03baB/TNF-\u03b1/NLRP3 inflammatory axis. Although fibrosis-associated transcriptional responses were detected, the absence of histological fibrosis suggests transcriptional priming of fibrogenic pathways rather than established fibrogenesis. Collectively, these findings provide a transcriptomic framework linking oxidative stress, impaired detoxification, inflammatory activation, and stress-responsive signaling to MCD-induced hepatic injury. The MCD model provides a valuable experimental platform for characterizing hepatic stress-response transcriptomes and for generating hypotheses that can subsequently be evaluated in environmentally relevant toxicological models. Nevertheless, caution should be exercised when extrapolating these findings to obesity-associated human MASLD, as the MCD model lacks key metabolic features of the human disease, including obesity and insulin resistance. Therefore, the present findings should be interpreted primarily as transcriptomic signatures of stress-induced hepatic injury rather than as a direct representation of the pathophysiological processes underlying human obesity-associated MASLD.",

This study investigated the potential effects of dietary Artemisia ordosica Krasch (ARI) supplementation on muscle n-3 PUFA deposition in Albas White Cashmere goats, possibly mediated through the regulation of antioxidant capacity, lipid oxidation, and metabolism. Under the present experimental conditions, ARI supplementation did not significantly affect growth performance, but significantly reduced ruminal C18:0 content (p < 0.05) and increased n-3 PUFA levels (C18:3n3, C22:6n3) in rumen fluid, plasma, liver, and Longissimus dorsi, and the consequent elevation of the muscle PUFA-to-saturated fatty acid ratio (P/S; p < 0.05). Concurrently, ARI supplementation enhanced ruminal and systemic antioxidant capacity, as evidenced by increased glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities, elevated total antioxidant capacity (T-AOC), and upregulated expression of antioxidant-related genes (GSR, GOR, SOD2). Integrated multi-omics analyses revealed that these improvements may be associated with the reduced relative abundance of the core biohydrogenating bacterium s_Butyrivibrio_fibrisolvens and de novo saturated fatty acid synthesis, and potential involvement of the AMPK signaling pathway, with downregulation of FASN; coordinated upregulation of CD36, ACSL3/4, and ELOVL6/7; and upregulation of PPARGC1A, collectively suggesting a promotion of FA oxidation and n-3 PUFA deposition. Collectively, these findings suggest that ARI-promoted n-3 PUFA enrichment in goat meat may be associated with the coordinated modulation of ruminal biohydrogenation, systemic antioxidant capacity, and intermediary lipid metabolism, providing a potential nutritional strategy for developing functional cashmere goat meat.",

However, the post-transcriptional mechanisms underlying senescence-associated collagen decline remain poorly understood. Here, we investigated the effects of chlorella hot water extract (CHWE) on mitochondrial function and collagen production in senescent human fibroblasts. CHWE restored mitochondrial membrane potential, ATP production, and redox balance through upregulation of SOD2. Notably, CHWE increased collagen protein levels without altering COL1A1 mRNA, indicating post-transcriptional regulation. miRNA profiling across young, senescent, and CHWE-treated senescent fibroblasts revealed that miR-193a-5p was upregulated during senescence (1.73-fold) and normalized by CHWE treatment. Functional validation confirmed that miR-193a-5p mimic suppressed COL1A1 protein. These findings identify a senescence-miR-193a-5p-COL1A1 axis in which age-dependent miR-193a-5p accumulation represses collagen translation, and CHWE reverses this process. By simultaneously restoring mitochondrial bioenergetic capacity and relieving miRNA-mediated translational repression, CHWE promotes efficient collagen recovery in senescent cells through complementary mechanisms. This study reveals a translational regulatory mechanism of collagen decline during cellular aging and highlights CHWE as a functional food supplement and a potential multi-target agent for age-related tissue deterioration.",

This study investigated whether apigenin protects against cisplatin-induced cardiac injury via modulation of CD38-Sirt3 signaling. Male Sprague Dawley rats were assigned to three groups, (1) Control, (2) Cisplatin (5 mg/kg), and (3) Pretreatment with apigenin (50 mg/kg/day) plus cisplatin groups. Then, left ventricular (LV) function, cardiac injury, oxidative stress, inflammation, apoptosis, and CD38-Sirt3 signaling-related proteins were assessed. Cisplatin impaired LV function and induced cardiac injury, oxidative stress, inflammation, and apoptosis in rats. These changes were accompanied by increased cardiac CD38 and decreased cardiac Sirt3 and SOD2 expression. Apigenin significantly improved LV function (%LVEF and %LVFS), reduced cardiac injury (LDH, CK-MB), attenuated oxidative stress, suppressed inflammatory responses (TNF-\u03b1, IL-1\u03b2, p-NF-\u03baB, TLR-4), and inhibited apoptosis (Bax/Bcl-2, cleaved caspase-3). Notably, apigenin improved cardiac SOD2 expression and reversed the alteration of CD38-Sirt3 signaling in cisplatin-treated rats. This study provides evidence that cisplatin-induced cardiotoxicity is associated with alterations in CD38-Sirt3 signaling. Apigenin attenuated LV dysfunction and cardiac injury, reduced oxidative stress, inflammation, and apoptosis, potentially through CD38-Sirt3 signaling. These findings highlight the cardioprotective potential of apigenin against cisplatin-induced cardiotoxicity.",

In this study, sodium salt-assisted modification was adopted to treat ZIF-8, and the chlorine-doped derived carbon materials HNC-Tx-Cl were prepared for peroxymonosulfate activation and tetracycline degradation in water. Compared with NC-800 fabricated by direct calcination of ZIF-8 at 800 \u00b0C, HNC-800-Cl synthesized via NaCl-assisted calcination exhibits more abundant pore structures and richer carbon defects, with a specific surface area of 1115 m2/g and a high graphitic defect ratio ID/IG of 1.20. Catalytic tests reveal that HNC-800-Cl achieves 93.39% tetracycline removal within 90 min at a catalyst dosage of 0.05 g L-1 and PMS concentration of 0.1 mM. The system possesses a strong anti-interference ability toward complex water environments, maintaining a favorable degradation performance in the presence of coexisting anions, natural organic matter and actual water matrices. It also exhibits outstanding cycling stability, retaining a removal rate of 80.34% after five recycling runs. Radical quenching experiments and EPR characterization verify that superoxide radical (\u00b7O2-) is the dominant reactive species during tetracycline degradation. Both the radical and non-radical pathways are clarified to illustrate the mechanisms of PMS activation and pollutant degradation. This work provides a novel catalytic material strategy to overcome the deficiencies of conventional PMS-AOPs, and offers a new perspective for structural regulation and non-metallic doping modification of ZIF-8-derived carbon materials.",

Transplantation of adipose-derived stem cells (ADSCs) may be an effective therapeutic strategy for delaying progression or restoring neurological function in ALS. We evaluated the safety and therapeutic efficacy of intravenous (i.v.) and intracerebral (i.c.) ADSC injection in a late-stage ALS patient and in a SOD1 transgenic (Tg) mouse model. Magnetic resonance imaging (MRI) and computed tomography (CT) were conducted to examine potential cerebral hemorrhage and tumor generation in the treated patient. In addition, maximal inspiratory pressure, maximal expiratory pressure, tidal volume, and respiratory rate were measured as indices of respiratory function. ADSC transplantation was safe, with MRI and CT showing no hemorrhage or tumorigenesis up to 12 months. The patient's Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score improved from 7 to 9 at 3 months and remained above baseline for 6 months. Respiratory function was preserved during this period. In SOD1 Tg mice, i.c. and i.v. ADSC infusion significantly prolonged survival (165.0 \u00b1 10.4 and 147.3 \u00b1 4.5 days vs. 129.7 \u00b1 3.9 days) and improved motor scores (P < 0.01).

In this study, we investigated the protective effects of ERG on high-fat diet (HFD)-induced cardiac fibrosis in the spontaneously hypertensive rats (SHR). ERG treatment (50 mg/kg daily, for 10 weeks) attenuated cardiac remodelling, as evidenced by reduced levels of the fibrosis markers hydroxyproline, \u03b1-smooth muscle actin, and galectin-3 increased by HFD. HFD induced obesity and altered plasma concentrations of metabolic hormones (thyroxine, leptin, and FGF21) and these changes were not affected by ERG. ERG suppressed SMAD-2 expression, indicating inhibition of TGF\u03b2-driven profibrotic signalling, and favourably modulated extracellular matrix composition by reducing the collagen I content as well as the collagen I/collagen III ratio. In parallel, ERG enhanced antioxidant defence, as shown by upregulated expression of Sod2, which encodes mitochondrial superoxide dismutase, and reduced expression of the profibrotic Nox4, thereby demonstrating protective actions in the heart. ERG supplementation prevented the HFD-induced increase in the neutrophil-to-lymphocyte ratio, which is a biomarker of the stress response and immune burden. In summary, ERG attenuated HFD-induced maladaptive cardiac remodelling in SHR rats by modulating extracellular matrix composition and reducing fibrosis markers, likely by mitigating the pro-oxidative state. These findings suggest that ERG supplementation could serve as an adjunctive strategy to prevent cardiovascular disease in individuals with hypertension who consume a Western-type diet.",

Here we developed RAG-17, an siRNA-targeting SOD1, using an accessory oligonucleotide conjugate platform for enhanced central nervous system (CNS) delivery. Preclinically, RAG-17 rescued motor neuron degeneration, delayed disease progression, preserved motor function and extended survival in SOD1G93A ALS rodents, even with advanced-stage treatment. In cynomolgus monkeys, intrathecal RAG-17 led to dose-dependent, durable reductions in SOD1 mRNA (CNS) and protein (cerebrospinal fluid (CSF)). In a first-in-human trial in patients with SOD1-ALS (n\u2009=\u20096), participants were assigned to two cohorts-cohort 1 (n\u2009=\u20093) received an initial 60\u2009mg dose (seven doses total) and cohort 2 (n\u2009=\u20093) received an initial 90\u2009mg dose (six doses total). The dose was escalated in 30\u2009mg steps to maintenance doses of 150\u2009mg (n\u2009=\u20095) or 180\u2009mg (n\u2009=\u20091). Thus, the primary safety endpoint was met, showing acceptable safety and tolerability. Treatment-emergent adverse events (TEAEs) occurred in 33% of participants (two of six). All TEAEs were mild to moderate, including muscle tremor (two patients) and elevated alanine aminotransferase (one patient), all of which resolved. No serious adverse events were reported. Furthermore, no other clinically meaningful changes were observed in laboratory parameters, vital signs, the ALS Functional Rating Scale-Revised score, physical or neurological examinations or ECG. The key secondary endpoints showed CSF SOD1 reductions of 69% (cohort 1, day 240) and 56% (cohort 2, day 210), and plasma neurofilament light chain reductions of 62% (cohort 1) and 52% (cohort 2), from baseline; no patient required invasive mechanical ventilation or died by the end of the study. These results demonstrate a favorable safety outcome, supporting the continued clinical evaluation of RAG-17 for SOD1-ALS. ClinicalTrials.gov registration: NCT05903690 .",

Dehydrocostus lactone (DHE), a blood-brain barrier-permeable sesquiterpene lactone with established anti-inflammatory activity, represents a promising but unexplored therapeutic candidate for ALS/FTD. The therapeutic effects of DHE were evaluated in primary mouse and human astrocytes expressing ALS/FTD-associated RNA-binding protein pathology, ALS patient-derived fibroblasts, and primary cortical neurons exposed to astrocyte-conditioned medium. Drosophila models expressing mutant FUS or TDP-43 in glial cells were used to assess locomotor performance and survival. Molecular analyses examined nuclear factor kappa B (NF-\u03baB) signaling, nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant responses, protein aggregation, mitochondrial function, and inflammatory mediator production. Plasma concentrations of inflammatory cytokines and chemokines were measured in patients with sporadic ALS. DHE exerted neuroprotective effects through a dual mechanism involving suppression of NF-\u03baB-dependent inflammatory signaling and activation of NRF2-mediated antioxidant pathways in astrocytes exhibiting FUS or TDP-43 proteinopathy. DHE attenuated astrocyte-mediated neurotoxicity and improved neuronal mitochondrial function in conditioned-medium assays. In addition, DHE reduced pathological FUS accumulation in FUS P525L-expressing astrocytes and in stress-challenged patient-derived fibroblasts. In Drosophila models, DHE significantly improved locomotor function and extended survival. Translationally, the chemokines CXCL10, CCL3, and CCL19 were elevated in plasma from patients with ALS, were induced by FUS or TDP-43 pathology in astrocytes, and were suppressed by DHE treatment, supporting the clinical relevance of the inflammatory pathways targeted by DHE. DHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms. The consistent therapeutic effects observed across mouse and human cellular models, patient-derived samples, and in vivo Drosophila models support further investigation of DHE as a potential therapeutic strategy for ALS/FTD and highlight astrocyte-mediated signaling pathways as actionable targets in neurodegenerative disease.",

Here, we integrated network toxicology, machine learning, immune infiltration analysis, single-cell RNA sequencing, molecular docking, molecular dynamics simulation, and in vitro assays to define the mechanisms linking long-term PFOA exposure to osteosarcoma. We identified 28 shared targets between PFOA-associated proteins and osteosarcoma-related genes, which were mainly enriched in oxidative stress, immune regulation, and metabolic reprogramming pathways. Machine learning prioritized nine candidate hub genes, including PNP, SOD2, MAT1A, RELA, PSAT1, CXCL12, PHGDH, PDK4, and CFD, with PHGDH, PSAT1, PDK4, and MAT1A suggesting a metabolism-related axis relevant to PFOA-associated osteosarcoma alterations. Single-cell and immune analyses showed distinct cell-type-specific expression patterns of these genes and their close associations with the tumor immune microenvironment. Molecular docking and molecular dynamics simulations further suggested potential structural compatibility between PFOA and several prioritized hub proteins. Experimentally, prolonged exposure to non-cytotoxic concentrations of PFOA enhanced osteosarcoma cell proliferation and invasion, whereas high concentrations were cytotoxic. Collectively, these findings suggest that long-term PFOA exposure may promote osteosarcoma progression by coupling environmental stress with metabolic reprogramming and immune dysregulation.",

The nanofibers were fabricated by electrospinning and characterized by FTIR and SEM, confirming successful incorporation of the extract and morphological changes in fiber structure. MTT and LDH assays showed that both formulations maintained cell viability under oxidative stress, while scratch assays indicated enhanced fibroblast migration. RT-qPCR results demonstrated that PVP-F\u00a0+\u00a0ME significantly downregulated CoCl\u2082-induced expression of HIF-1\u03b1, IL-1\u03b2, IL-6, and TNF-\u03b1, and normalized antioxidant-related genes such as SOD2 and GPx. Antibacterial testing revealed selective activity against Gram-positive bacteria (Staphylococcus aureus and Enterococcus faecalis). Overall, the findings suggest that PVP-based nanofibers, particularly when enriched with madimak extract, provide protective, anti-inflammatory, and antimicrobial effects with potential applications in wound healing.",

Nevertheless, the molecular mechanism of placental dysfunction in GDM are still not clear, especially the role of ferroptosis and its interplay with oxidative stress, inflammation, and angiogenesis. Placental tissues from GDM pregnancies were examined to assess oxidative stress, antioxidant defense, ferroptosis regulation, inflammatory signaling, and angiogenic pathways. Expression levels of key molecular markers were evaluated, and correlation analyses were performed to identify mechanistic interrelationships. GDM placenta demonstrated elevated oxidative stress markers, including P22PHOX and TXNIP, accompanied by reduced antioxidant markers, such as HO-1, NQO1, SOD2, and CAT, indicating impaired cellular defense. Ferroptosis regulation was disrupted, as anti-ferroptotic markers GPX4, SLC7A11, and NRF2 were significantly downregulated, while pro-ferroptotic markers TFR1 and ACSL4 were increased, suggesting enhanced iron accumulation and lipid peroxidation. This was accompanied by heightened inflammation, evidenced by increased IL-6, IL-1\u03b2, TNF-\u03b1, and NF-\u03baB activation, alongside reduced IL-10 expression. Furthermore, angiogenesis was impaired, reflected by decreased VEGFA, HIF-1\u03b1, and SDF-1\u03b1 levels, highlighting poor vascular development in the placenta. Additionally, Correlation analyses demonstrated strong associations between ferroptosis markers and oxidative stress, inflammatory, and angiogenic pathways, suggesting the possible presence of an interconnected regulatory network. These findings identify ferroptosis as a central regulator of GDM-associated placental dysfunction, through a possible interconnected network of oxidative stress, inflammation, and impaired angiogenesis. Targeting ferroptosis may offer a possible therapeutic option to restore placental function and improve maternal-fetal outcomes in GDM.",

Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.",

The antioxidant machinery may play a crucial role in this area; however, this has been neglected in previous research. The main aim of this study was to assess the effect of ELF-EMF exposure (5\u2009days, 1\u2009Hz, 100\u2009mT, 2\u2009h/day) on ROS levels, expression levels of antioxidant genes, and apoptosis induction in different breast cancer molecular subtypes with different p53 statuses. DCFH-DA results revealed that the ROS level increased in all three cell lines (SKBR-3, MDA-MB-231, and MCF-7); this increase was much greater in SKBR-3 (up to 5-fold compared to its sham exposure). This result was concurrent with the annexin V/PI results; SKBR-3\u2009cells showed much more apoptosis induction (about 78%), compared with the others (22% or 11% in the other two cells). On the other hand, the mRNA expression level of SOD1 and SOD2 increased significantly in the MDA-MB-231, in addition to these two genes, the expression level of SOD3 and GSR increased in the MCF-7\u2009cells but not in the SKBR-3. Taken together, our results confirmed that ELF-EMF induced ROS-dependent apoptosis, especially in HER-2-enriched breast cancer cells (the SKBR-3), in a p53-independent manner. Other molecular subtypes (MDA-MB-231 as TNBC, or MCF-7 as luminal A) showed resistance against the ROS level increasing and subsequent apoptosis induction by using antioxidant genes, especially SOD1.",

While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.",

In this study, we performed an integrated analysis of the SK-MEL-30 melanoma cell line using function-focused quantitative proteomics and amino acid profiling. Proteins were quantified using a label-free normalized spectral abundance factor (NSAF) approach, while intracellular amino acids were measured by LC-MS/MS. Functional enrichment analyses based on KEGG and Gene Ontology were used to associate protein expression patterns with metabolic pathways. A total of 148 proteins were identified, predominantly representing high-abundance and functionally relevant components of metabolic and structural pathways. Key cytoskeletal proteins, including vimentin and S100A11, were among the most abundant, consistent with a mesenchymal-like and potentially invasive phenotype. Metabolic profiling revealed elevated expression of glycolytic enzymes such as PKM and LDHA, consistent with a glycolytic shift. Increased levels of l-glutamine and l-glutamic acid, together with GOT2 expression, suggest an active glutamine aspartate axis supporting tricarboxylic acid cycle activity and nitrogen metabolism. In addition, elevated levels of stress-response proteins, including HSP90 and SOD2, indicate a proteostatic network adapted to metabolic stress. Although the proteome coverage is lower than that reported in large-scale deep proteomic studies, the NSAF-based workflow was designed to capture the most abundant and functionally relevant proteins, providing a focused overview of the major metabolic and structural characteristics of SK-MEL-30 melanoma cells. Overall, this integrative analysis highlights the coordination between metabolic reprogramming and cytoskeletal organization in SK-MEL-30\u202fcells and suggests that glutamine-dependent metabolic pathways warrant further investigation as potential therapeutic targets in melanoma.",

This study focused on yellow cheek carp (Elopichthys bambusa, initial body weight: 221.36\u00a0\u00b1\u00a06.75\u00a0g; initial body length: 28.47\u00a0\u00b1\u00a00.56\u00a0cm) to explore how short-term (8\u00a0days) and long-term (28\u00a0days) starvation influence intestinal morphology, expression of key functional genes, and gut microbiota composition. Additionally, Spearman's rank correlation analyses were conducted to explore potential host-microbe interactions. The results showed that short-term starvation did not significantly affect intestinal muscle layer thickness or villus height, but markedly upregulated genes associated with autophagy and apoptosis such as bcl-2-associated X protein 2 (bax2), bcl-2-like protein 1 (bcl2l1), and cysteine-aspartic acid protease 8(casp8). It also increased microbial diversity and altered the composition of dominant gut microbiota. In contrast, long-term starvation significantly suppressed the expression of copper/zinc superoxide dismutase (Cu-Zn sod), casp3a, and casp9, increased the number of goblet cells, inhibited muscle layer development, and weakened the correlation between gut microbes and host gene expression. In summary, short-term starvation appears to maintain intestinal homeostasis through activation of autophagy- and apoptosis-related pathways in conjunction with microbial restructuring. However, prolonged starvation inhibited muscularis development, increased goblet cell density, downregulated antioxidant and immune-related gene expression, and weakened the associations between the host and its microbiota. These findings provide new insights into starvation-induced physiological responses and contribute to gut health management strategies in aquaculture.",

Here, the induction, resuscitation and functional recovery of the viable but nonculturable (VBNC) state in the efficient QQ bacterium Brucella sp. ZJ1 was investigated under salinity and combined phenol-salinity stress. Combined stress markedly accelerated VBNC formation (36\u2009h vs. 10\u2009days under salinity alone) and caused greater oxidative damage, metabolic suppression, structural deterioration and loss of QQ activity. Salinity-induced VBNC cells recovered following stress removal, whereas phenol-salinity-induced cells required resuscitation-promoting factor (Rpf) for efficient revival. Rpf-mediated resuscitation substantially restored both QQ activity and biofilm inhibition capacity. Transcriptomic analysis revealed that VBNC formation was accompanied by coordinated repression of genes involved in central metabolism, DNA replication and protein biosynthesis, together with activation of osmotic adaptation, membrane transport, quorum sensing and oxidative stress response pathways. These findings demonstrate that the VBNC state is an active adaptive strategy that preserves the potential for functional recovery and provides new insights for improving the antifouling performance of QQ-based MBR systems treating high-strength industrial wastewater.",

To address this, we developed a hydrogel nanocomposite (MCAG-Gel) tailored for postoperative glioma treatment, which is constructed by gel loading manganese-doped hollow cerium oxide nanoparticles (MnOx/CeOx, MC NPs) and the chemotherapeutic drug axitinib (AG). MCAG-Gel adheres to the post-surgery wound and is responsive to the weakly acidic tumor microenvironment (TME), releasing MC NPs and AG for chemotherapy. Interestingly, MC NPs exhibit peroxidase-like (POD) activity and catalase-like (CAT) activity in the TME, generating reactive oxygen species (ROS) to inhibit residual glioma cells while depleting glutathione to amplify oxidative stress and alleviate tumor hypoxia. Conversely, under physiological conditions, MC NPs exhibit CAT-like and superoxide dismutase (SOD)-like activities, scavenging ROS to protect normal tissues from oxidative damage. MCAG-Gel shows good biosafety and potent anti-tumor efficacy against postoperative residual tumors in a subcutaneously implanted glioblastoma model. Collectively, these findings highlight the potential of MCAG-Gel as a promising therapeutic strategy for clinical postoperative glioma treatment.",

Observed differences in neurotoxicity between conventional and liposomal formulations are poorly characterized mechanistically. This study aimed to systematically compare their neurotoxicity profiles and investigate the underlying mechanisms, testing the hypothesis that the parent drug irinotecan contributes directly to neurotoxicity. We employed a multi-dimensional strategy. Computational toxicology predicted neurotoxicity for irinotecan and its metabolite SN-38. Disproportionality analysis of the FDA Adverse Event Reporting System (FAERS) compared real-world neurotoxicity signals. Network pharmacology and molecular docking explored irinotecan's direct molecular targets and pathways. Multi-platform computational prediction confirmed high neurotoxicity risk for both irinotecan and SN-38. FAERS analysis revealed a distinct clinical profile: conventional irinotecan (C-Irinotecan) was associated with both central (CNS) and peripheral nervous system (PNS) adverse events, whereas liposomal irinotecan (L-Irinotecan) signals were confined to the periphery. This CNS-specific disparity, combined with pharmacokinetic evidence, implicated the parent drug. Network analysis identified eight core neural targets (e.g., AKT1, EGFR) with high binding affinity to irinotecan. Pathway enrichment highlighted the MAPK/p38 cascade as a central mechanism. This integrated analysis demonstrates a formulation-dependent neurotoxicity dichotomy for irinotecan. We propose and provide converging evidence for a novel paradigm: prototype irinotecan is a direct mediator of neurotoxicity, and its CNS access dictates central effects. These findings offer critical insights for formulation safety and neuroprotective strategies.",

The present study was designed to evaluate how a six-week regimen of hypoxia exposure and SIT influences redox balance and myokine production in the skeletal muscle of high-fat diet (HFD) (21% fat, 1.5% (w/w) cholesterol; 43% (w/w) sucrose-free carbohydrate, 4.554\u00a0kcal/g)-fed atherosclerotic ApoE-/- mice. Forty male ApoE-/- mice fed a HFD were randomly assigned to four groups: Control-Normoxia, Control-Hypoxia, SIT-Normoxia, and SIT-Hypoxia. The hypoxia protocol involved exposures to 11.2% oxygen three times (40\u00a0min each) per week. Key assessment parameters included plasma lipid profiles, skeletal muscle reactive oxygen species (ROS), protein carbonyls, key components of the Nrf2 antioxidant pathway, glutathione metabolism, and myokine-related markers. Compared with the control group, both hypoxia and SIT-Normoxia significantly reduced levels of ROS, protein carbonyls, and Vegfa165 mRNA expression in the skeletal muscle. Hypoxia alone enhanced the levels of GSH-synthesizing enzymes and promoted myokine production. SIT-Normoxia improved plasma lipid profiles, activated the Nrf2 pathway, enhanced the GSH system, and upregulated myokines. SIT under hypoxia further reduced ROS and Vegfa165 while increasing plasma HDL-C and levels of SOD1 protein in the skeletal muscle, but failed to synergistically activate the Nrf2 pathway or enhance GSH production. Paradoxically, both intervention combinations suppressed the mRNA expression of myokine precursor Fndc5, BAIBA-synthesizing enzyme Hadh and Hadha. Overall, six weeks of isolated hypoxia exposure or SIT training independently reduced oxidative stress and promoted beneficial myokine responses in the skeletal muscle of ApoE-/- mice fed a HFD. The wild-type (WT) mice fed a low-fat diet (LFD) was included to validate successful induction of hyperlipidemia, vascular remodeling, and skeletal muscle oxidative stress in ApoE-/- mice after six weeks of HFD feeding.",

Recently, novel antioxidant functions of deuterated polyunsaturated fatty acids (D-PUFAs) in preventing LPO in the membranes and in humans have been reported by many research groups. The preventive and therapeutic potential of D-PUFAs against LPO and related diseases has received considerable attention, but the underlying molecular mechanisms and dynamics remain elusive. This hypothesis article summarizes state of the art preventive effects of D-PUFAs against LPO and cell damage reported in the literature and discusses the plausible mechanisms of action with an emphasis on the effects of membrane properties. Interestingly, it was found that cholesterol and oleic acid as well as D-PUFAs did not inhibit LPO in homogeneous solution, but they all suppressed LPO in the liposomal membranes, cell membranes, and partially in vivo. It is speculated that D-PUFAs suppress LPO in the membranes, at least in part, by physically obstructing the reaction between lipid peroxyl radicals and phospholipid substrates as well as by chemical and biochemical mechanisms. However, the proposed mechanism remains a hypothesis which should be validated directly in future experimental studies. D-PUFAs which have high affinity for phospholipids suppress lipid peroxidation (LPO) in the membranes, but not in solution.The preventive effects of D-PUFAs against LPO and oxidative damage were observed consistently in experimental animals.The preventive effects of D-PUFAs against oxidative damage were partially observed in human clinical studies.D-PUFAs suppress LPO in the membranes not by scavenging radicals but by physically obstructing interactions between radicals and phospholipids.",

This study evaluated vacuum steam pulse blanching (VSPB), gliding arc cold plasma (CP; 30-120\u00a0s), hot water blanching, and sequential VSPB-assisted CP (B-CP) pretreatments for improving drying efficiency and quality retention. Among combined treatments, VSPB followed by 30\u00a0s CP exposure (B-CP30) was optimal because it significantly accelerated moisture removal while maintaining structural integrity and high folate retention (p\u00a0<\u00a00.05). B-CP30 enhanced surface porosity, reduced contact angle, improved membrane permeability, and promoted uniform moisture redistribution, thereby reducing drying resistance and shortening drying time compared with untreated samples (p\u00a0<\u00a00.05). Longer plasma exposures caused excessive structural and oxidative damage. Pretreatment significantly affected shrinkage, rehydration ratio, folate, total phenolics, and flavonoids after drying (p\u00a0<\u00a00.05). Short-duration B-CP is therefore promising for high-quality dried yardlong bean pods.",

However, its neurodevelopmental toxicity and underlying mechanisms remain poorly understood. Using a three-stage human embryonic stem cell (hESC-H9) neural differentiation model, cells were exposed to 375\u202f\u03bcM BPS, 375\u202f\u03bcM BPS\u00a0+\u00a05\u202f\u03bcM NMDAR inhibitor (MK801), 375\u202f\u03bcM BPS\u00a0+\u00a05\u202f\u03bcM ERK pathway inhibitor (U0126), and a 0.1% DMSO solvent control, respectively. High-content screening, qPCR, and Western blot were utilized to analyze neuromorphology, intracellular Ca2+ levels, and related genes/proteins expression. Results showed that NMDAR inhibition effectively rescued BPS-induced Ca2+ dyshomeostasis and deficits in neurite complexity. Both NMDAR and ERK inhibition exacerbated apoptosis at the precursor stage but effectively reduced it at post-maturation stages. Mechanistically, BPS hyperactivates NMDAR, leading to Ca2+ influx as the primary event, which suppresses BDNF and synaptic proteins, impairing synaptogenesis and promoting apoptosis. ERK is activated downstream but independently regulates neuronal morphology rather than serving as a linear executor of NMDAR-driven toxicity. Collectively, NMDAR is the pivotal mediator of BPS neurotoxicity, and the NMDAR-ERK axis involves both convergent and divergent mechanisms, underscoring the need for stage-specific neuroprotective strategies.",

Natural antioxidant enzymes, chiefly superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), are the principal enzymatic defenses against oxidative stress, but their clinical use is limited by poor stability, short half-life, and high cost. Nanozymes, producible at scale with tunable, stable activity, offer a promising alternative. This review is organized around a mechanistic distinction essential to the literature but frequently blurred: antioxidant nanozymes, which net-scavenge ROS through reversible redox cycling, versus pro-oxidant nanozymes, which net-generate ROS through Fenton-type chemistry. Cerium oxide nanoparticles (CeO2 NPs) are examined as the prototypical antioxidant nanozyme, their SOD- and CAT-like activities arising from reversible Ce3+/Ce4+ cycling and oxygen-vacancy chemistry at the surface, with the Ce3+/Ce4+ ratio determining which activity predominates. Magnetite nanoparticles (Fe3O4 NPs) are examined as the prototypical pro-oxidant nanozyme, dominated by peroxidase-like Fenton chemistry driven by surface Fe2+/Fe3+ cycling that generates hydroxyl radicals, exploited for antibacterial and antitumour applications, with CAT-/SOD-like activity arising only as a secondary, concentration- and pH-dependent behaviour. Beyond mechanism, this review surveys the expanding application space for both classes, including ROS/analyte sensing, antibacterial therapy against resistant pathogens, diabetic wound healing, treatment of ROS-associated disease, and catalysis by related metal-oxide nanocatalysts. By keeping the two tracks mechanistically distinct, this review provides a clearer framework for rational nanozyme-based therapeutic design.",

Cardamine hupingshanensis is a selenium\u2011hyperaccumulating plant species endemic to China, exhibiting strong tolerance and high capacity for accumulation in high\u2011selenium environments. Glutathione S\u2011transferases (GSTs) are important enzymes involved in diverse metabolic processes and stress responses, yet systematic identification and functional characterization of the GST gene family in this species remain incomplete. In this study, a genome\u2011wide identification of the GST gene family in C. hupingshanensis was performed using bioinformatics approaches, and the phylogenetic relationships, gene structures, conserved motifs, physicochemical properties, and subcellular localizations were systematically analyzed. A total of 61 ChGST genes were identified and classified into eight subfamilies, with the Tau and Phi subfamilies being the most abundant. Three representative Tau subfamily genes (ChGSTU4-3, ChGSTU16-1, and ChGSTU24), which exhibit divergent tissue\u2011specific and selenium\u2011responsive expression patterns and belong to separate phylogenetic clades, were selected for subsequent functional characterization. Prokaryotic recombinant expression vectors were constructed via gene cloning, and the recombinant proteins were expressed in Escherichia coli and purified. The temperature and pH adaptability, metal ion responses, and enzymatic kinetic parameters of the fusion proteins were determined, and their antioxidant activities were evaluated using the disk diffusion method. In vitro enzymatic assays showed that all three fusion proteins exhibited high catalytic activity in the range of 30-50 \u00b0C and pH 7.0-8.0. Different metal ions exerted distinct regulatory effects on ChGST enzyme activity: Na+, K+, and Ca2+ had negligible effects, whereas the other tested ions showed various degrees of inhibition. The disk diffusion assay demonstrated that ChGSTU4-3, ChGSTU16-1, and ChGSTU24 protected bacterial cells from oxidative stress induced by hydrogen peroxide. This study delineates the basic characteristics and in vitro functions of the GST gene family in C. hupingshanensis, providing preliminary experimental evidence that may contribute to understanding the molecular basis of selenium tolerance in this species, as well as a theoretical reference for mining stress\u2011responsive genes and for the bioremediation of selenium\u2011contaminated environments.",

Previously we showed that ATCV-1 infects mouse macrophages, stimulates production of inflammatory cytokines, and accelerates motor neuron disease in the Amyotrophic Lateral Sclerosis (ALS) model SOD1-G93A transgenic mice. This, coupled with significantly elevated levels of serum IgG1 antibody to ATCV-1 in ALS patients compared with healthy controls, suggests involvement of ATCV-1 in ALS. Herein, using serum and CSF from a different ALS cohort we again show elevated antibodies to ATCV-1 in ALS patients compared with healthy controls. To assess ATCV-1 in human macrophages, we challenged immature (IMM), M0, M1, and M2 human THP-1 macrophage cells containing an Interferon Stimulated Response Element (ISRE) promoter-reporter with ATCV-1 or its Major Capsid protein (MCP) glycans. ATCV-1 infected M1 THP-1 to a greater degree than IMM, M0, or M2 THP-1. The initial high ISRE-promoter activity of M1 THP-1 was suppressed by the MCP-Glycans of ATCV-1. M0, but not IMM or M2 THP-1 produced IL-6 in response to ATCV-1 or its MCP-glycan, while high levels of IL-6 from unchallenged M1 THP-1 increased further by ATCV-1 or its MCP glycan. In contrast, ATCV-1 or its MCP-Glycan significantly reduced the high levels of IL-10 produced by M2 THP-1. Thus, antibody to ATCV-1 in ALS patients and the susceptibility of human M1 macrophages to ATCV-1 infection with boosted inflammatory cytokine and diminished anti-inflammatory cytokine production suggest that ATCV-1 may contribute to ALS motor neuron disease.",

To address these problems, a SalB-loaded liquid crystalline nanoparticle delivery system (SalB-LCN) was constructed and systematically characterized in terms of its physicochemical properties. Meanwhile, an intranasal administration strategy was employed to bypass the BBB, and the therapeutic effects of SalB-LCN on VD were systematically evaluated. The results showed that SalB-LCN possessed favorable morphology and sustained-release properties, enabling stable encapsulation and continuous release of SalB. In vitro experiments demonstrated that SalB-LCN exhibited good biocompatibility and could alleviate oxidative damage in neuronal cells. In a bilateral common carotid artery occlusion-induced rat model of VD, SalB-LCN significantly improved learning and memory abilities, alleviated hippocampal neuronal morphological damage, and exhibited good in vivo biosafety. Further studies showed that SalB-LCN markedly lowered reactive oxygen species levels, suppressed IL-1\u03b2 and IL-18 production in hippocampal tissues, and reduced cell death as well as lactate dehydrogenase activity. In addition, SalB-LCN also suppressed NLRP3/Caspase-1/GSDMD signaling. In conclusion, intranasal delivery of SalB-LCN improved brain delivery by facilitating transport across the BBB and conferred neuroprotection against VD through modulation of oxidative stress, inflammation, and NLRP3/Caspase-1/GSDMD signaling, highlighting its translational potential as a nanomedicine-based therapeutic strategy.",

In the present study, lanthanum-based nanostructures (La-based NCs) were prepared using an eco-friendly method employing Arabic gum and spermine, and their efficacy in alleviating Pb-stress-induced oxidative damage in Zataria multiflora was investigated. The plants were subjected to different levels of Pb contamination (0, 250, 500, and 750\u00a0mg/kg) and then treated with La-based NCs at doses ranging from 0 to 200\u00a0ppm. The effect of Pb toxicity (750\u00a0mg/kg) led to an increase in indicators of oxidative stress, including H\u2082O\u2082 and MDA, along with a significant decrease in the activity of phytochemicals and antioxidant response. Treatment with La-based NCs significantly improved these effects dose-dependently, showing the optimal dose at 100\u00a0ppm. At 100\u00a0ppm of La-based NCs treatment, oxidative damage was decreased by 40-60%, whereas antioxidant responses were stimulated by 35-70%. Simultaneously, metabolic stability was enhanced through the recovery of essential oils and related phytochemical characteristics. Particularly, La-based NCs stabilized with Arabic gum consistently showed greater activity than those stabilized with spermine, suggesting a stabilization-mediated influence on redox reactions and plant-NCs interactions. This study demonstrates that green-synthesized La-based NCs have potential applications as modulators of oxidative stress and antioxidants within the plant system under Pb stress.",

Adult studies have explored the links between circadian rhythms and neurological or metabolic diseases, but research in pediatric populations remains limited. In infants and children, circadian systems undergo rapid maturation, and this developmental window is particularly vulnerable to disruption from maternal, environmental, or endogenous factors. The aim of this review is to examine how circadian mechanisms intersect with inflammatory and oxidative pathways in pediatric neurological disorders, highlighting both mechanistic insights and therapeutic potential. We conducted a narrative review of PubMed/MEDLINE and complementary sources, covering studies published between January 2016 and March 2025, with relevant studies selected for detailed synthesis. Evidence shows that oxidative stress and inflammation are exacerbated by immature circadian control, with glial circadian clocks, clock genes, and cytokine-melatonin interactions playing important roles. Melatonin is frequently identified as a key circadian-regulated mediator in pediatric conditions, including hypoxic-ischaemic encephalopathy, autism spectrum disorder, metabolic encephalopathies, and sepsis. Preclinical and translational studies demonstrate that melatonin reduces oxidative damage, maintains mitochondrial function, and modulates immune responses, while early clinical data indicate that it is safe and holds promise as an adjunctive therapy. The review further emphasizes that circadian regulation of oxidative stress is shaped by maternal signals, melatonin in breast milk, and environmental exposures in neonates, particularly in preterm infants. Despite growing evidence, major gaps remain, including the lack of pediatric-specific chronotherapy trials, standardized dosing protocols, and time-stamped biospecimen studies. We suggest a feasible roadmap for future melatonin-based pediatric chronotherapy trials, linking mechanistic insights to clinical application. Overall, advancing circadian biology, particularly through melatonin, offers a promising avenue for pediatric neuroprotection and opens new directions for chronotherapy in vulnerable populations.",

S-glutathionylation is an important redox modification regulating mitochondrial homeostasis, yet its role in skeletal aging remains unclear. The objective of this study is to systematically investigate the role of Grx2 deficiency-mediated CD36 S-glutathionylation in BMSC senescence and SOP development. Grx2, p53, and p21 expression in human and mouse BMSCs were analyzed by immunohistochemistry (IHC), western blotting (WB), and polymerase chain reaction (PCR). Aging-related and ovariectomy-induced osteoporosis models were established in Grx2-/- mice for bone metabolism and senescence assessments. BMSC senescence, osteogenesis, and adipogenesis were evaluated by SA-\u03b2-Gal and WB, ALP/ARS staining, and ORO staining. Transcriptomic and S-glutathionylated proteomic analyses were performed to identify underlying mechanisms. Fatty acid uptake was quantified using two-color flow cytometry. DAG and MDA levels were measured to assess lipid overload and oxidative injury. Mitochondrial structure and function were evaluated by TEM, Mitotracker, qPCR, NAD+/NADH, ATP, ROS, JC-1, and Seahorse assays. The PI3K/AKT pathway was assessed by WB. Co-IP confirmed CD36 S-glutathionylation, and molecular docking predicted C272 as the key modification site. CD36-C272S mutation and Grx2 overexpression were applied to validate functional mechanisms in vitro and in vivo. Grx2 deficiency, in both male and ovariectomized female mice, accelerates bone loss, inhibits osteoblast formation without altering osteoclast function, and exacerbates BMSC senescence. Through integrated transcriptomic and S-glutathionylated proteomic analysis, we identified the fatty acid transporter CD36 as a critical downstream target of Grx2. Notably, Grx2 deficiency markedly increases the S-glutathionylation of CD36, which not only enhances its fatty acid uptake capacity, leading to the accumulation of toxic lipid metabolites and oxidative damage, but also impairs mitochondrial energy metabolism by inhibiting the PI3K/AKT signaling pathway. Overexpression of Grx2 or the C272S mutation in CD36, which disrupts its S-glutathionylation, can break this harmful cycle and inhibit BMSC senescence. Grx2 deficiency-mediated CD36 S-glutathionylation drives BMSC senescence and SOP, providing new insight into the redox regulatory mechanisms underlying skeletal aging.",

The molecular pathogenesis of this complex disease, however, remains elusive. Long-read sequencing technologies, with their ability to produce long, continuous reads, offer enhanced resolution for genomic studies. This study utilizes this technology to reveal novel insights at the isoform level in preeclamptic placentas. In this study, we enrolled six participants, including three with normotensive pregnancies and three with preeclamptic pregnancies. By integrating Oxford Nanopore Technologies (ONT) long-read sequencing, Illumina short-read RNA-Seq, ATAC-seq, and Whole-Genome Bisulfite Sequencing (WGBS) of placental tissues, we generated an isoform-resolved transcriptome. We identified a total of 48,175 isoforms, encompassing 19,584 previously unannotated splice variants from known genes and 2,744 novel isoforms from the newly identified loci. Furthermore, we found that epigenetic modifications in promoter regions trigger alternative first exon usage, leading to additional novel isoforms of key preeclampsia regulators (e.g., ADARG1). This study expands the known transcriptomic landscape of the human placenta, revealing tens of thousands of previously unannotated isoforms. Integration of cross-platform validation and multi-omics datasets not only confirmed the robustness of these findings but also provided insights into their potential biological functions. The resources generated here establish a valuable foundation for future investigations into placental development and the molecular mechanisms of preeclampsia.",

Rotenone, a potent inhibitor of mitochondrial complex I, is widely used to model Parkinson-like pathology because it induces oxidative damage and selective loss of dopaminergic neurons. In the present study, Drosophila melanogaster was employed to investigate rotenone-induced neurotoxicity and to evaluate the protective potential of hesperidin, a naturally occurring flavonoid known for its antioxidant and anti-apoptotic activities. Exposure to rotenone resulted in reduced survival rates, impaired locomotion and climbing ability, elevated reactive oxygen species (ROS) levels, increased protein oxidation, and heightened caspase-3 activity, reflecting neurodegenerative changes. Notably, co-treatment with hesperidin mitigated these adverse effects by enhancing motor performance, decreasing oxidative stress markers, and suppressing apoptotic signaling. Collectively, these findings suggest that hesperidin offers significant protection against rotenone-induced neurotoxicity in D. melanogaster, highlighting its potential as a therapeutic candidate for neurodegenerative disorders.",

Maternal autoantibodies may elicit systemic exaggerated immune responses involving type I interferon (IFN) signalling cascade, yet peripheral circulating immunity in CHB pathogenesis remains poorly understood. To investigate this, we performed single-cell RNA sequencing (scRNA-seq), followed by differential expression gene (DEG) analysis, SCENIC analysis, pseudotime analysis and cell communication analysis, to characterize systemic immune alterations in foetuses with CHB treated with dexamethasone and validated key findings by real-time quantitative PCR (qPCR) and flow cytometry. Compared with controls, CHB foetuses exhibited a markedly activated inflammatory response involving both IFN and NF-\u03baB pathways. Although monocytes showed significant changes in cellular proportions, upregulated DEGs and interferon-stimulated genes, prioritized cellular responses and enhanced intercellular interactions. Notably, THBS1+CD14+ monocytes had a pro-inflammatory phenotype with upregulated NLRP3 inflammasome-related genes and maturation toward a pro-inflammatory state, and Thbs1 conditional knockout mice showed reduced IL-1\u03b2 levels in BMDMs. Additionally, dexamethasone-treated monocytes had downregulated SOD2 (anti-apoptotic) levels compared to controls, confirmed by qPCR, and flow cytometry verified that dexamethasone promoted monocyte apoptosis. In conclusion, the peripheral immune system in CHB is characterized by innate immune activation driven mainly by monocytes, along with systemic inflammation including IFN signalling. THBS1+/CD14+ monocytes represent a distinct proinflammatory phenotype potentially linked to NLRP3-mediated inflammatory responses.",

Antimicrobial photodynamic therapy (aPDT), as an alternative strategy, produces reactive oxygen species (ROS) under light activation and kills drug-resistant bacteria through oxidative damage. Nevertheless, conventional photosensitizers (PSs) are limited by aggregation-caused quenching, inadequate bacterial selectivity, and off-target cytotoxicity. Quaternary ammonium salts (QASs) can preferentially accumulate on bacterial membranes through electrostatic interactions and disrupt the bacterial membranes. The quaternary ammonium PS PK4, reported here has a triphenylamine unit that enhances ROS production. Under white light irradiation, PK4 produces abundant ROS that oxidatively damage bacterial membranes, while exhibiting high photostability and minimal dark toxicity. In an MRSA-infected wound model, PK4-mediated phototherapy can reduce inflammation, accelerate wound healing, and enhance collagen deposition without systemic toxicity, providing a promising aPDT strategy for combating drug-resistant bacterial infections.",
        "42483214": "ID: 42483214\nTitle: Diquat-induced organ toxicity: a focus on regulated cell death pathways and mitochondrial dysfunction.\nAbstract: Diquat (1,1'-ethylene-2,2'-bipyridyl, DQ) is a herbicide widely used for weed control in both agricultural and non-cultivated areas. Although its acute toxicity is lower than that of paraquat, its high-water solubility and stability in acidic and neutral environments contribute to its prolonged environmental persistence. As DQ gradually replaces paraquat in agricultural practice, the incidence of DQ poisoning has increased significantly. DQ poisoning typically results from accidental ingestion, suicidal intake, or improper agricultural handling. To date, no specific antidote is available, and the high mortality associated with DQ poisoning presents a critical challenge for clinical management. Accumulating evidence indicates that the toxicity of DQ is primarily attributed to its capacity to generate reactive oxygen species (ROS), leading to oxidative stress and subsequent oxidative damage to lipids, proteins, and DNA, ultimately resulting in multi-organ dysfunction, with the kidneys and intestines being the primary target organs. The pathogenesis of DQ poisoning involves multiple factors, including oxidative stress imbalance, regulated cell death, mitochondrial dysfunction, and disturbances in energy metabolism. This review systematically examines the physicochemical properties, metabolic characteristics, biodistribution, and target organ toxicity of DQ, with a particular focus on the interplay between excessive ROS production and mitochondrial dysfunction in the context of oxidative stress. Furthermore, we provide an in-depth discussion on the roles of regulated cell death-including pyroptosis, ferroptosis, and mitophagy-and metabolic dysregulation in DQ-induced toxicity. In addition, this review summarizes the classical signaling pathways involved in organ dysfunction, current therapeutic strategies, and potential intervention targets, thereby offering a theoretical framework and future research directions for the management of DQ poisoning.",

This study aimed to elucidate the mechanisms underlying mTOR inhibitor resistance and to evaluate the therapeutic potential of multidrug combinations in \u03b2-catenin-mutant HCC. MHCC97H and SNU449 cells were transfected with 4EBP1WT, 4EBP1A4, or HSP90\u03b2 expression plasmids and then treated with rapamycin to assess their effects on ferroptosis and rapamycin sensitivity. The role of 4EBP1 in regulating ferroptosis was further explored by Western blotting, co-immunoprecipitation, and immunofluorescence. The inhibitory effects of mTOR inhibitors (rapamycin, MLN0128), ERK inhibitors (PD901), and their combination (MLN0128 + PD901) on tumor cells were evaluated. HCC mouse models were generated via hydrodynamic tail vein injection of c-Met/\u03b2-catenin\u0394N90 or c-Met/\u03b2-catenin\u0394N90/4EBP1A4 plasmids to evaluate the therapeutic effects of the four treatment regimens. Rapamycin more potently inhibited mTOR/RPS6 than mTOR/4EBP1 and concurrently induced ferroptosis. 4EBP1A4 promoted ferroptosis and potentiated rapamycin efficacy. Mechanistically, 4EBP1A4 competitively bound HSP90\u03b2, displacing Keap1, thereby increasing Keap1-Nrf2 complex formation and promoting Nrf2 degradation. Furthermore, rapamycin, MLN0128, PD901, and their combination reduced p-4EBP1 levels, induced ferroptosis, and inhibited HCC cell proliferation, thereby suppressing tumor growth, with the combination exhibiting the strongest effect. 4EBP1A4 enhances Nrf2 ubiquitination and degradation via the HSP90\u03b2/Keap1 axis, relieving mTOR-mediated ferroptosis suppression and synergistically improving rapamycin efficacy. Additionally, rapamycin, MLN0128, and PD901 suppress HCC progression by inducing ferroptosis, with their combination showing superior potency.",

Here, we report transgenic melon (Cucumis melo) plants overexpressing miR398 and miR408 precursors, two conserved miRNAs involved in copper-related regulatory pathways and associated with stress response. Engineered plants exhibited enhanced vegetative development, including stem elongation, internode formation, root architecture, and leaf production. The significant increased accumulation of well-processed miR398 and miR408, along with the downregulation of their respective targets (Copper/Zinc Superoxide Dismutase and Basic Blue Protein) demonstrates the functional activity of the transgenes. Sequencing analysis revealed a positive correlation in the accumulation of miR398 and miR408, suggesting a coordinated accumulation pattern with interdependent miRNA regulation, potentially independent of conventional transcription factor activity. Transgenic plants showed improved tolerance to drought, salinity, heat, and cold stress, validating the role of miR398 and miR408 as master regulators of abiotic stress resilience in melon. This work highlights the potential of biotechnological strategies based on engineering Cu-related miRNAs to enhance crop performance under different adverse environments, thereby contributing to agricultural sustainability in the face of climate change.",

This study purified two polysaccharides (GSP1 and GSP2) from Ganoderma sinense, a traditional Chinese medicine, and investigated their potential therapeutic effects against AD. GSP1 and GSP2 were purified and characterized for key physicochemical properties, including monosaccharide composition and molecular weight. In vitro neuroprotective efficacy was evaluated using glutamate-challenged SH-SY5Y cells. For in vivo assessment, an AlCl\u2083/D-galactose induced AD mouse model was established to quantify cognitive/memory enhancement. Multiomic analysis of the gut microbiota, Short-Chain Fatty Acid (SCFAs) metabolomics, and behavioural tests were conducted to elucidate the therapeutic mechanisms of GSP1. Both GSP1 and GSP2 conferred neuroprotection against toxin-induced damage. Notably, GSP1 demonstrated superior efficacy compared with GSP2, significantly enhancing cognitive/ memory performance and reducing amyloid-\u03b2 plaque deposition. Furthermore, GSP1 changed gut microbial diversity and SCFA metabolic profiles. Critical genus-level correlations emerged: Turicibacter, Jeotgalicoccus, and Staphylococcus were positively associated with therapeutic outcomes, whereas Odoribacter was negatively associated. Natural polysaccharides, particularly GSP1, demonstrate therapeutic potential against AD by modulating gut microbiota. Mechanistically, this effect is linked to reshaping microbial communities and affecting the production of neuroprotective SCFAs. Although these findings position GSP1 as a promising AD therapeutic candidate, deeper exploration of gut-brain axis mechanisms remains essential for clinical translation. GSP1 emerges as a promising therapeutic candidate for AD, offering a new approach to developing AD-targeted pharmaceuticals and nutraceuticals.",

Methods: Case report. Results: In a 72-year-old male with non-SOD1 ALS, rapid decline on the ALS functional rating scale revised (ALSFRS-R) and a rise in serum neurofilament light chain (NfL) concentration were observed following 3 loading doses of an SOD1 ASO before the patient succumbed to disease. The time from symptom onset to death was 9\u2009months. Discussion: While treatment was initiated relatively late (\u223c7\u2009months) after symptom onset and follow-up duration was short, the observed increase (as opposed to a reduction) in serum NfL and accompanying rapid functional decline, suggest the lack of a therapeutic effect in someone with fast progressing non-SOD1 ALS.",

Thirty-two male Sprague-Dawley rats were randomly assigned to either a control group or HFD groups with exposure periods of 4, 8, or 12 weeks. Outcome measures included body weight, inflammatory markers (IL-6, TNF-alpha, MCP-1), oxidative stress parameters (MDA, SOD, GSH), apoptotic activity, and protein expression levels of key components within the signaling pathway. The results demonstrated that body weight and systemic inflammation progressively increased with the duration of HFD intake. Markers of oxidative stress became significantly elevated by week 8 and further deteriorated by week 12, characterized by increased malondialdehyde (MDA) levels, diminished antioxidant capacity (reduced SOD and GSH), and enhanced apoptosis. A reduction in Sirt3 expression and increased acetylation of PGC1alpha were detected at 8 weeks, while by 12 weeks, dysregulation extended across the entire NAD+/Sirt1/PGC1alpha pathway. These alterations were associated with exacerbated oxidative damage. The findings suggest that the duration of HFD exposure plays a critical role in the development of skeletal muscle oxidative stress through progressive and time-dependent impairment of the NAD+/Sirtuins/PGC1alpha pathway.

Small changes in the chemistry of pools where leaf litter tend to accumulate can have major effects on amphibian physiology and ecology. This work studied effects of pine needles on Odontophrynus reigi tadpoles. We exposed tadpoles to different concentrations of pine needles (0, 0.5, 1.5 and 2.5 g/L). In tadpoles, we determined: 1) morphological endpoints, 2) growth rate and development stage, 3) oxidative stress parameters (catalase, glutathione-S-transferase, lipid peroxidation (LPO) and protein oxidation (PO)) and 4) genetic damage (micronucleus, erythrocytes nuclear abnormalities and mitotic index). Dissolved oxygen (DO), pH, ammonia and total phenols (TP) were determined in water. As pine needle concentration increased, DO, pH and ammonium decreased in water, and TP increased. All morphological endpoints increased as pine needle increased, except body width that decreased. Oxidative damage had opposite effects: LPO decreased 50%, and PO had a 3-fold increase at 2.5 g/L. Catalase and glutathione-S-transferase enzymatic activities did not change significantly. Mitotic index increased with pine needle concentration. These physiological responses, likely driven by changes in water chemistry, suggest a potential long-term cost for individuals inhabiting pine monocultures.",

We hypothesized that common GBA polymorphisms would be associated with subtle parkinsonian features, mild cognitive impairment, and \"silent\" Lewy body (LB) pathology in aging individuals without a clinical diagnosis of parkinsonism. The most prevalent GBA variants, T369M and E326K, appear in the general population at rates of approximately 0.6% and 1%, respectively. We evaluated 845 participants from the Oregon Alzheimer's Disease Research Center (OADRC) with SNP data generated by the National Centralized Repository of Alzheimer's Disease (NCRAD). Twenty-one subjects were E326K carriers and eighteen were T369M carriers. Clinical measures and postmortem neuropathology were compared between each SNP group and non-carriers. Although there were no statistically significant clinical differences related to synucleinopathy across groups, neuropathological analyses revealed a significantly higher prevalence of LB pathology in E326K carriers compared to T369M carriers. When stratifying each genetic group by LB status (LB+ or LB-), LB+ E326K carriers demonstrated a significant reduction in Mini-Mental State Examination (MMSE) scores compared with LB- non-carriers and a modest decrease compared with T369M carriers. These preliminary findings from a small, uni-center cohort suggest that the E326K GBA polymorphism may predict LB pathology and subtle cognitive decline in aging individuals who lack overt parkinsonian symptoms. Further validation in a larger cohort is warranted. Identifying at-risk individuals through targeted genetic screening may ultimately support earlier intervention and preventative care strategies. Understanding How Two Common GBA Gene Variants Affect Brain Aging in People Without Parkinson's Disease: What We Learned by Comparing Thinking Abilities and Brain Changes in Older AdultsThis study explored whether two common changes in the GBA gene, called E326K and T369M, influence how the brain ages in people who never developed Parkinson's disease during life. We wanted to learn whether these genetic differences affect thinking or memory and whether they are linked to changes in the brain that are usually seen only after symptoms appear. This question matters because many people now learn about their genetic risks through medical or consumer testing, yet doctors often do not have clear information about what these results mean for older adults who have no symptoms. To study this, we followed a large group of older adults who completed yearly thinking and movement tests and then donated their brains for research. This approach allowed us to compare their everyday functioning with the actual brain changes seen under the microscope. We found that people with the E326K variant showed more of the protein buildup typically linked to Parkinson's disease, even though they never showed the disease in life. They also tended to have lower memory scores. This suggests that E326K may contribute to \u201csilent\u201d brain changes long before symptoms appear. In contrast, people with the T369M variant did not show these harmful changes. They had no signs of Parkinson's-related protein buildup and tended to have fewer Alzheimer's-related changes as well, along with slightly better memory performance. These findings show that not all GBA variants act the same way. One variant may increase risk for early, hidden brain changes, while another may be neutral or even somewhat protective. Understanding these differences can help doctors better explain genetic test results, guide decisions about monitoring and follow-up, and support future research aimed at early prevention of brain diseases.",

Increasing evidence suggests that reduced clearance of metabolic waste and pathological proteins from the brain also contributes to disease onset and progression. Previous studies have often considered choroid plexus (CP) function, glymphatic exchange, and meningeal lymphatic drainage as separate clearance processes. A continuous framework linking these structures and functions is still lacking. This review integrates recent clinical and experimental evidence and proposes the brain clearance continuum as an interpretative framework. It describes three interlinked functional interfaces: the upstream choroid plexus-cerebrospinal fluid (CP-CSF) inflow interface, the midstream parenchymal perivascular exchange interface, and the downstream meningeal lymphatic outflow interface. Under physiological conditions, these interfaces support CSF movement, parenchymal solute exchange, and the outward removal of metabolic waste. In AD, disrupted CSF homeostasis, impaired perivascular exchange, and obstructed meningeal lymphatic outflow may interact, leading to serial failure of the brain clearance continuum. This process is closely associated with A\u03b2/tau accumulation, vascular dysfunction, neuroinflammation, and cognitive decline. We also summarise potential therapeutic strategies directed at different clearance interfaces, whilst emphasising that most evidence remains preclinical or exploratory. The brain clearance continuum provides a systematic framework for understanding clearance failure in AD. It may also offer a theoretical basis for future mechanistic studies and therapeutic development that are stratified by clearance interface and disease stage.",

This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap. To overcome the current therapeutic plateau, we advocate for multinode interventions that combine amyloid-targeting therapies with clearance-enhancing agents, supported by a readiness-tiered imaging strategy-standardized proxies such as DTI-ALPS and PVS burden as enrichment/secondary endpoints and dynamic contrast-enhanced MRI for mechanistic proof-of-concept.",

While conserved miRNAs have been extensively characterized, the agronomic roles of lineage-specific miRNAs in crops remain largely unexplored. Here, we demonstrate that tae-miR5048, a wheat-specific miRNA, functions as a master regulator concurrently modulating plant architecture and drought tolerance. Overexpression of tae-miR5048 enhanced early root growth, accelerated reproductive transition, and optimized plant architecture and grain morphology without compromising grain yield. Conversely, CRISPR/Cas9-mediated knockout of TaMIR5048 homoeologs impaired root development and delayed flowering, yet promoted vegetative growth and grain yield potential, revealing a bidirectional regulatory role. Cytological analysis showed that tae-miR5048 optimizes plant height, flag leaf size and grain dimension by fine-tuning cell proliferation and expansion in a tissue-specific manner. Moreover, tae-miR5048 confers drought resilience throughout the growth cycle by elevating osmolyte accumulation to maintain tissue water status and alleviating oxidative damage through suppression of ROS production and membrane lipid peroxidation. Mechanistically, degradome sequencing, RLM\u20115' RACE, and transient co\u2011expression assays demonstrated that tae-miR5048 directly targets and downregulates multiple kinase genes, including receptor-like protein kinases and mitogen-activated protein kinases, thereby modulating key signalling hubs post-transcriptionally. Transcriptome profiling further revealed that tae-miR5048 fine-tunes architectural traits by regulating cellular growth-related genes and enhances drought tolerance through activation of stress-responsive and proline biosynthesis pathways. Collectively, our findings establish tae-miR5048 as a central integrator that balances plant architecture and drought adaptation, providing the first functional evidence for a lineage-specific miRNA as a promising target for breeding climate-resilient wheat varieties.",

Although multiple pathological processes have been individually implicated, the mechanisms linking neurotransmitter deficits, proteinopathies, circuit vulnerability, and neurodegeneration remain insufficiently integrated. Here, we synthesize current evidence on the pathophysiology of cognitive impairment in PD, emphasizing the convergence of dopaminergic, cholinergic, noradrenergic and serotonergic dysfunction with \u03b1-synuclein, tau and amyloid-\u03b2 pathology. We highlight the hippocampus - particularly the CA2 subregion - as a critical anatomical hub connecting synaptic dysfunction, memory impairment, and dementia progression. Accumulating evidence identifies oxidative stress and neuroinflammation as central drivers across these pathological domains. Among endogenous sources of reactive oxygen species, NADPH oxidases (NOX), especially Nox4, emerge as key regulators of redox imbalance, protein aggregation and glial-neuronal interactions. Increased Nox4 activity correlates with hippocampal damage and cognitive decline, whereas experimental inhibition of Nox4 preserves synaptic integrity and improves memory performance in preclinical models. By integrating molecular, cellular and systems-level findings, this review positions redox dysregulation - and NOX-dependent signaling in particular - as a unifying mechanism underlying cognitive decline in PD, and discusses emerging therapeutic strategies targeting redox pathways, highlighting NOX modulation as a promising approach to modify the course of Parkinson's disease-associated cognitive impairment.",
        "42485855": "ID: 42485855\nTitle: Pharmacological inhibition of GPR84 attenuates acute ovarian ischemia-reperfusion injury in mice via activation of AMPK and suppression of the NLRP3 inflammasome.\nAbstract: Ovarian ischemia-reperfusion injury (OIRI) causes oxidative damage, inflammation, and tissue destruction, frequently causing tissue damage and inflammation. Although G protein-coupled receptor 84 (GPR84) operates as a modulator of immune cell activation across numerous pathological contexts, its specific contributions to OIRI pathophysiology remain insufficiently characterized. We therefore examined whether pharmacological blockade of GPR84 confers protection against OIRI and delineated the operative signaling networks. Utilizing a murine model of bilateral ovarian ischemia followed by reperfusion, we administered either PBI-4050 or BGT-004 to evaluate therapeutic efficacy. Our analyses revealed pronounced GPR84 upregulation within ovarian tissues subjected to ischemic insult. Tissue fractionation experiments showed that GPR84 upregulation occurred predominantly in CD45\u207a leukocytes. Both antagonistic compounds substantially mitigated histological deterioration while attenuating lipid peroxidation (malondialdehyde accumulation), oxidative radical generation (nitric oxide), and neutrophil infiltration (myeloperoxidase activity), concomitantly enhancing antioxidant defense (superoxide dismutase function) and curtailing secretion of IL-1\u03b2 and IL-18. Additionally, treatment suppressed NOX-4 expression and thwarted NLRP3 inflammasome assembly, reflected in diminished NLRP3 protein abundance and reduced caspase-1 cleavage. GPR84 blockade also reduced gasdermin D cleavage, indicating suppression of pyroptotic cell death. Mechanistically, GPR84 blockade reinstated AMPK\u03b1 phosphorylation status and restored phosphorylation of the downstream AMPK substrate acetyl-CoA carboxylase; however, co-administration of the AMPK antagonist Compound C with BGT-004 nullified these protective actions, suggesting that AMPK signaling contributes to therapeutic efficacy. The Compound C mechanistic validation was performed using BGT-004, the selective GPR84 antagonist, to avoid confounding from PBI-4050's GPR40 agonist activity. These observations collectively suggest that GPR84 antagonism ameliorates OIRI through AMPK-dependent suppression of NLRP3 inflammasome activity, identifying this receptor as a candidate for further investigation in ischemia-reperfusion injury.",
        "42485859": "ID: 42485859\nTitle: Symbiosis modulates pharmaceutical toxicity and contaminant fate in the Azolla-Nostoc system.\nAbstract: Pharmaceutical contamination in aquatic environments frequently occurs as complex mixtures; however, the extent to which biological interactions modify the toxicity and fate of contaminants remains poorly understood. Here, we investigated the physiological, biochemical, ecotoxicological, and phytoremediation responses of Azolla filiculoides cultivated in the presence (A+N) or absence (A-N) of Nostoc flagelliforme exposed to hydroxychloroquine (HCQ), ivermectin (IVE), and azithromycin (AZI), applied individually across environmentally relevant to elevated exposure concentrations (0-200\u00a0\u03bcg\u00a0L-1) and in fixed-ratio mixtures (2\u00a0\u03bcg\u00a0L-1 per compound). IVE induced the strongest physiological disruption, impairing photosynthetic performance, increasing oxidative stress, and destabilizing nitrogen metabolism, whereas HCQ produced intermediate effects and AZI caused comparatively weaker responses. Symbiosis was associated with higher ecotoxicological thresholds for several physiological endpoints, with threshold values differing by up to two orders of magnitude between A-N and A+N plants. Compared with A-N plants, A+N plants generally maintained higher photosynthetic performance, lower oxidative damage, and higher nitrogen-related metabolite concentrations, including elevated NH4+, glutamate, glutamine, and total-N concentrations. Symbiosis was also associated with differences in pharmaceutical fate in a compound-specific manner. For AZI and IVE, enhanced removal efficiency coincided with lower tissue accumulation, whereas HCQ exhibited both greater removal and higher internal retention under symbiotic conditions. Collectively, these findings indicate that symbiosis modulates pharmaceutical responses, ecotoxicological sensitivity, and contaminant fate in a compound-specific manner, highlighting the importance of biological interactions in shaping ecotoxicological responses and pharmaceutical attenuation in aquatic plant-microbe systems.",
        "42485915": "ID: 42485915\nTitle: Stearoyl CoA desaturase 1 deficiency increases ferroptosis susceptibility in chicken embryonic liver cells.\nAbstract: Ferroptosis is an iron-dependent form of programmed cell death driven by lipid peroxidation. It is increasingly recognized as a contributor to liver cell injury. Stearoyl-CoA desaturase 1 (SCD1) is a rate-limiting enzyme in monounsaturated fatty acid synthesis. It plays a key role in maintaining lipid homeostasis and may affect cellular susceptibility to ferroptosis. However, it remains unclear whether SCD1 restrains ferroptosis-associated injury in chicken embryonic liver (CEL) cells. Therefore, this study aimed to investigate the role of SCD1 in regulating ferroptosis susceptibility and cellular injury related to ferroptosis in CEL cells, with a focus on its effects on lipid metabolism, oxidative stress, and iron homeostasis. The results showed that SCD1 knockdown reduced intracellular lipid droplet area, triglyceride, and total cholesterol levels in CEL cells (P < 0.05). In addition, SCD1 knockdown induced mitochondrial ultrastructural changes associated with ferroptosis, including mitochondrial shrinkage, increased membrane density, and cristae disruption. It also aggravated oxidative stress, as shown by increased reactive oxygen species, oxidized glutathione, and malondialdehyde levels and decreased glutathione content (P < 0.05). SCD1 knockdown reduced cell viability, whereas oleic acid or ferrostatin-1 treatment partially reversed this decrease (P < 0.05). Moreover, SCD1 knockdown increased ACSL4 expression and decreased SLC7A11, GPX4, and Nrf2 expression at both the mRNA and protein levels (P < 0.05). SCD1 knockdown further reduced mitochondrial membrane potential and increased lipid peroxidation, intracellular Fe\u00b2\u207a levels, and total iron content (P < 0.05). In contrast, SCD1 overexpression increased lipid accumulation, reduced reactive oxygen species levels, increased glutathione content, increased SLC7A11, GPX4, and Nrf2 expression, and decreased ACSL4 protein expression (P < 0.05) without significantly affecting ACSL4 mRNA expression. These findings suggest that SCD1 regulates the susceptibility of CEL cells to ferroptosis and exerts a protective effect by improving lipid metabolism, antioxidant defenses, and mitochondrial function, indicating that SCD1 is a key regulatory factor in maintaining the homeostasis and health of chicken liver.",

However, the combined ecotoxicological effects of BF and PE MPs on soil organisms remain poorly understood. In this study, a controlled soil exposure experiment was conducted in which earthworms (Eisenia fetida) were exposed to BF (10\u202fmg/kg) and/or PE-MPs (30 \u03bcm, 2.5\u202fg/kg) for 14 and 28 days. The ecotoxicological effects were evaluated using integrated biochemical, histopathological, and transcriptomic approaches. Molecular dynamics simulations revealed that BF could spontaneously adsorb onto PE surfaces, with an adsorption energy of -30.58\u202fkcal/mol. Specifically, co-exposure to BF and PE-MPs significantly elevated ROS, which was 3.5% higher than in the BF group, and markedly inhibited AChE activity, which was 12.2% lower than in the BF group after 28 days, indicating enhanced oxidative stress and neurotoxicity. Prolonged exposure suppressed key antioxidants, including superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), indicating a transition from adaptive response to oxidative damage. Integrated biomarker analysis showed the highest IBR under co-exposure, with positive EAI values of 0.213 and 0.191 after 14 and 28 days, respectively, confirming persistent synergistic toxicity. Histopathological observations confirmed aggravated tissue injury, particularly in the intestinal epithelium and muscle layers, under combined exposure. Transcriptomic analysis revealed that co-exposure induced broader transcriptional perturbations involving stress-responsive signaling, membrane-associated dysfunction, and detoxification transport pathways. Overall, PE-MPs amplify BF toxicity through synergistic interactions, highlighting the importance of considering pollutant co-exposure and carrier effects in ecological risk assessment of contaminated soils.",

Although this review focuses on human spermatozoa and oocytes, it also incorporates mechanistic and translational evidence from mammalian animal models, including mouse, bovine, buffalo, caprine, and porcine studies, where direct human evidence remains limited. This distinction is essential, as several mechanisms of cryodamage have been defined experimentally in animal models, necessitating careful consideration of their applicability to human gametes. Spermatozoa and oocytes differ substantially in structural organization, metabolic activity, and regulatory mechanisms, resulting in distinct patterns of cryosensitivity. In spermatozoa, limited cytoplasmic volume, high membrane polyunsaturated fatty acid content, and compacted chromatin increase susceptibility to osmotic stress, oxidative damage, and membrane destabilization during freezing-thawing. Reactive oxygen species are central mediators of sperm cryodamage, contributing to DNA fragmentation, chromatin decondensation, altered protamine-histone balance, and epigenetic changes involving DNA methylation, histone modifications, and RNA profiles. Oocytes are particularly sensitive to temperature fluctuations, cryoprotectant exposure, and spindle disruption because of their complex cytoskeletal organization, mitochondrial activity, and dynamic epigenetic regulation. Cryopreservation-associated damage to the meiotic apparatus, mitochondrial function, and chromatin architecture may promote aneuploidy, DNA strand breaks, and transcriptomic alterations. Overall, this review summarizes current evidence on genetic and epigenetic alterations associated with gamete cryopreservation, highlights mechanisms of cryodamage, and discusses their translational and clinical relevance.",

In our previous work, a series of merocyanine fluorescent probes were designed, synthesized and evaluated for the imaging of A\u03b2 plaques. Here, we further identified the representative probe D4, which not only demonstrates the characteristics of a highly sensitive fluorescent probe for real-time imaging of A\u03b2 content in the brain of APP/PS1 mice, but also exhibited the ability to treat AD, including inhibition of A\u03b2 aggregation (inhibition rate: 89.5%), antioxidant activity (3.4 times that of Trolox); AChE inhibitory activity (IC50\u00a0=\u00a00.5\u00a0\u00b1\u00a00.0\u00a0\u03bcM) and the capacity to cross the BBB (Pe\u00a0=\u00a08.6\u00a0\u00b1\u00a00.7). Additionally, D4 dramatically attenuates A\u03b2-induced SH-SY5Y cell death by preventing the generation of ROS, and intravenous administration of 0.5\u00a0mg/kg D4 for 15\u00a0days significantly improved the cognitive ability of 7-month-old APP/PS1 mice by protecting hippocampal and cortex neurons from necrosis, attenuating oxidative stress in the hippocampus and cortex, and reducing A\u03b2 burden deposition. These findings strongly suggest that D4 owns a high theranostic potential for treating AD.",

By modulating the expression of neuronal and stress-response genes, REST contributes significantly to neuroprotection. REST is predominantly localised in the nucleus; however, in Alzheimer's Disease (AD), nuclear REST is reduced, leading to transcriptional dysregulation and contributing to AD pathology. The low levels of REST are associated with defective autophagy flux, including mitochondrial dysfunction and enhanced vulnerability to toxic protein aggregates, causing AD and other neurodegenerative disorders. Recent research shows that REST suppresses several apoptotic genes, modulating neuroinflammatory signalling and regulates autophagy. The specific regulatory mechanism of REST suggests new strategies for the prevention and treatment of AD and ageing. Despite REST's unique functions and importance in AD, its precise role and the molecular mechanisms underlying REST-mediated signalling pathways have not been comprehensively reviewed. The purpose of this review is to provide an overview of the structural and functional characteristics of REST, explore the mechanisms underlying REST-mediated autophagy, neuroinflammation and apoptosis in AD and discuss the emerging therapeutic implications of targeting REST.",

These two enzymes play central roles in cellular NADPH generation. In pepper fruit, two genes were identified in the transcriptome, designated Ca6PGDH1 and Ca6PGDH2, which appear to encode a peroxisomal and a plastidial putative isozyme, respectively. During ripening, Ca6PGDH1 exhibited only minor changes in its expression, whereas Ca6PGDH2 was markedly downregulated. The expression patterns of both genes diverged in response to exposure to a nitric oxide (NO)-enriched atmosphere and melatonin, while both NO and melatonin treatments partially mitigated the downregulation of Ca6PGDH2 but not that of Ca6PGDH1. At the enzymatic level, the total 6PGDH activity exhibited a modest decline during ripening. Isoenzymatic analysis using non-denaturing polyacrylamide gel electrophoresis revealed three distinct isozymes, designated 6PGDH I to III, in order of increasing electrophoretic mobility. In vitro assays examining the effects of various reducing agents, including glutathione (GSH) and L-cysteine (L-Cys), as well as signaling molecules such as NO, peroxynitrite (ONOO-), hydrogen sulfide (H2S), and cyanide, showed that the NO donors and H2S exerted inhibitory effects on some isozymes, with the strongest inhibition observed for Ca6PGDH III whereas reducing compounds (GSH and Cys) protected against these inhibitory effects. Together, these results highlight Ca6PGDH as a redox-sensitive enzyme that may contribute to metabolic and signaling homeostasis during pepper fruit ripening.",

Soluble amyloid-\u03b2 oligomers (A\u03b2Os) are important contributors to these early synaptic alterations by disrupting excitatory neurotransmission and impairing hippocampal function. Metformin (Met), a widely used antidiabetic drug, has recently gained attention for its potential neuroprotective properties; however, its effects on hippocampal synaptic transmission and plasticity under amyloid-induced stress remain incompletely understood. In the present study, we investigated the effects of orally administered Met (200 mg/kg/day) on basal excitatory synaptic transmission, presynaptic release probability, and long-term synaptic plasticity in hippocampal slices from rats subjected to stereotaxic injection of A\u03b2Os into the CA1 region. Using field electrophysiological recordings, we show that Met significantly enhances basal excitatory synaptic transmission, increases presynaptic release probability, potentiates long-term potentiation (LTP), and attenuates long-term depression (LTD). Notably, Met prevented the impairments in synaptic transmission and plasticity induced by A\u03b2Os, maintaining synaptic responses at levels comparable to those observed in control animals. Together, these findings indicate that Met modulates hippocampal synaptic function and preserves physiological forms of synaptic plasticity under amyloid-induced stress conditions. Our results identify synaptic transmission and plasticity as functionally relevant targets of Met action and support further investigation of Met as a potential strategy for preserving synaptic function during the early stages of AD.",

Estrogen receptor-dependent neural cellular signalling reduces TLR4-mediated immune priming and NF-\u03baB activation, preventing NLRP3 inflammasome assembly and pro-inflammatory cytokine release. Concurrently, estrogen increases SIRT1 activity, restoring metabolic and epigenetic equilibrium while inhibiting HMGB1 acetylation, translocation, extracellular release, and activation of the stress-response pathway. Coordinated regulation of the TLR4-NF\u03baB-NLRP3 and SIRT1-HMGB1 molecular triad reduces chronic neuroinflammation, preserves neuronal integrity, metabolic resilience, and slows persistent inflammation-driven brain ageing. This highlights estrogen and estrogen-based steroidal modulators as promising therapeutic candidates for reversing accelerated cognitive ageing and neurodegenerative disorders. However, a crucial research gap persists in the absence of a systems-level assessment of neurosteroids as a multi-target regulator of convergent innate immunological and metabolic signalling networks. The control of the TLR4-NF\u03baB-NLRP3 inflammasome axis and the SIRT1-HMGB1 metabolic-epigenetic checkpoint has not been well studied as an interrelated, steroidal druggable trifecta driving brain homeostasis and neurodegeneration. These pathways are often studied in isolation, despite overwhelming evidence that their bidirectional interplay contributes to persistent neuroinflammation, immunometabolic dysfunction, and cellular senescence. This review synthesises evidence from molecular endocrinology, biochemical, pre-clinical, and clinical models to advance a mechanistically integrated and therapeutically actionable framework that aligns into a unified endocrine, metabolic, and immune target-driven framework relevant to complex, inflammation-driven brain ageing, thereby offering a strong foundation and paving the way for future molecular target validation and disease-modifying, steroid-mimetic interventions against neurodegeneration.",

Agricultural pesticides and engineered nanoparticles are among the most pervasive stressors, often detected together in surface waters due to intensive farming practices and widespread industrial use. Spirotetramat (a systemic tetramic acid insecticide), methoxyfenozide (an ecdysone agonist), and zinc oxide nanoparticles (ZnO-NPs) were focused on as representative co-occurring contaminants with potential joint effects on aquatic organisms. To investigate their combined impacts, adult zebrafish (Danio rerio) were exposed for 21\u202fdays to single, binary, and ternary mixtures under sublethal conditions, and multibiomarker profiling was applied to integrate neurotoxicity, oxidative stress, endocrine disruption, and apoptosis. Sustained acetylcholinesterase inhibition indicated persistent neurotoxic stress, while GST and CAT induction, biphasic GPx regulation, and elevated TBARS, protein carbonyls, and 8-OHdG revealed overwhelmed antioxidant defenses and cumulative oxidative damage. Vitellogenin induction, particularly in males, provided clear evidence of endocrine disruption, and caspase-3 activation highlighted apoptotic stress compromising organismal resilience. Integrated biomarker response scores identified ternary mixtures as most disruptive, while joint toxicity analysis revealed synergistic interactions beyond additive expectations. Collectively, these findings provide mechanistic evidence that pesticide-nanoparticle mixtures intensify neurotoxicity, oxidative stress, endocrine disruption, and apoptosis in zebrafish. Our results underscore that mixture-based biomarker integration is critical for capturing ecologically relevant outcomes and advancing risk assessment of emerging contaminant combinations.",

Despite substantial progress in biomarker discovery, numerous challenges persist in the accurate diagnosis and prognosis of pediatric epilepsy. Glycosylation is known to play a critical role in neuronal function and neuroinflammation, but the differential glycome profile associated with the onset and progression of pediatric epilepsy has not been investigated. This study investigates the alterations in N-glycan signatures present in plasma and cerebrospinal fluid (CSF) from individuals experiencing focal and generalized epilepsy and developmental and epileptic encephalopathies (DEE). Discriminative models demonstrate distinct N-glycome profiles in both plasma and CSF that effectively differentiate between control subjects and those with epilepsy, identifying a specific set of 11 N-glycans common to both biological fluids. Notably, we observed a significant elevation in mannosylation and mono-sialylation of CSF in cases of DEE. High mannosylated and mono-sialylated N-glycans exhibited strong diagnostic potential for DEE. The biosynthetic network of CSF N-glycans indicated that sialylation, galactosylation, and bisection are the primary contributors to the transition from controls to DEE. Furthermore, the abundance of sialylation, fucosylation, and bisection correlated positively with the levels of proteins and sugars in CSF. These findings identify N-glycosylation changes in CSF as biosignatures associated with pediatric epilepsy, especially DEE, and support further evaluation of glycoprotein N-glycome profiling for disease classification and clinical stratification.",

The triterpenoid partition of Cimicifugae Rhizoma, named as 'Ximingting', is commercially used for perimenopausal syndrome. However, the anti-asthma constituents and mechanism of Cimicifugae Rhizoma, and the therapeutic effect of 'Ximingting' on asthma remain unknown. This study aims to illustrate anti-asthma constituents of Cimicifugae Rhizoma and 'Ximingting', and explored the underlying molecular mechanisms. The ethyl acetate fraction of Cimicifugae Rhizoma extract (EAEC) was prepared accroding to the manufacturing process of 'Ximingting'. The chemical composition of EAEC were analyzed by UPLC-MS/MS. An ovalbumin (OVA)-induced asthma mouse model was used for evaluateing the bioassay in vivo. Network pharmacology was adopted for predicting anti-asthmatic targets/pathways, validated by molecular docking, ELISA, Western blot, qRT-PCR, immunofluorescence, and flow cytometry. Fifty-eight constituents (mainly triterpenoids) were identified in EAEC. EAEC significantly attenuated OVA-induced airway inflammatory infiltration, reduced inflammatory cytokines, and restored Th1/Th2 balance in mice. Network pharmacology indicated that anti-asthmatic effect of EAEC was related to inflammation, oxidative stress, and T-cell differentiation. Further experiments demonstrated that EAEC activated Keap1-Nrf2 signaling to enhance antioxidant capacity, and inhibited STAT6 phosphorylation and GATA3 expression, thereby blocking CD4 T cell differentiation into Th2 cells. Triterpenoids in Cimicifugae Rhizoma exert anti-asthmatic effects by activating Keap1-Nrf2 pathway against oxidative stress and regulating STAT6/GATA3 pathway to balance immunity. These findings reveal the anti-asthmatic mechanism of Cimicifugae Rhizoma and suggest the potential of 'Ximingting' for further anti-asthmatic investigation.",

To better understand the mechanisms underlying spinal cord radiosensitivity, we developed a three-dimensional human spinal cord organoid model derived from human-induced pluripotent stem cells using a neuroectodermal differentiation protocol that closely mimics embryonic spinal cord development. Mature spinal cord organoids were exposed to a clinically relevant 2\u2009Gy dose of ionizing radiation, and subsequent assessments included evaluation of DNA damage, astrocytic response, and neuronal functionality. The organoids successfully recapitulated key features of spinal cord development, including neural differentiation, spontaneous electrophysiological activity, and functional maturation. Radiation exposure led to pronounced DNA double-strand breaks, particularly in SOX2-expressing progenitor cells. Astrocyte hyperplasia was evident through increased GFAP expression, indicating a reactive gliosis response. Electrophysiological analysis revealed a marked reduction in spike frequency and burst activity, indicative of impaired neuronal function. Although partial recovery was observed over time, functional deficits persisted, suggesting sustained damage. This human spinal cord organoid model offers a physiologically relevant platform for studying radiation-induced spinal cord injury and provides valuable insights into the cellular and functional consequences of radiation exposure. It holds significant potential for advancing neuroprotective strategies and therapeutic interventions targeting radiation-induced damage in the central nervous system.",

For discovery of new and efficient nematicidal agents, we developed a series of double 1,2,4-oxadiazole derivatives from our previous studies. Bioassays revealed that compounds B10 and B12 displayed 100% mortality against Bursaphelenchus xylophilus, Aphelenchoides besseyi and Ditylenchus destructor at 50\u2009\u03bcg\u2009mL-1. In particular, compound B10 was the most potent against B.\u2009xylophilus, showing a median lethal concentration (LC50) of 5.85\u2009\u03bcg\u2009mL-1, which outperformed the lead compound tioxazafen (LC50\u2009=\u2009180.02\u2009\u03bcg\u2009mL-1) by a clear margin. Preliminary mechanistic investigations indicated that B10 significantly suppressed the feeding and reproductive capacity of B.\u2009xylophilus, and induced substantial accumulation of intracellular reactive oxygen species, lipofuscin and lipids, accompanied by elevating malondialdehyde levels and suppressed activities of antioxidant-related enzymes, and then triggerred oxidative damage by disrupting redox homeostasis. Transcriptome analysis indicated that B10 strongly affected gene expression, with most the differentially expressed genes mainly associated with the neuroactive ligand-receptor interaction pathway. These results were further supported by quantitative reverse-transcription PCR analysis and acetylcholinesterase activity assays. The present work indicated that double 1,2,4-oxadiazole compound B10 is a promising nematicide for managing nematode diseases. \u00a9 2026 Society of Chemical Industry.",
        "42486577": "ID: 42486577\nTitle: Oral squamous cell carcinoma (OSCC): An overview.\nAbstract: Oral cavity cancer comprises malignancies arising from anatomical sites within the oral cavity, including the gingiva, buccal mucosa, anterior two-thirds of the tongue (oral or mobile tongue), hard palate, floor of the mouth, retromolar area, and mucosal surface of the lip. More than 90% of oral cavity cancers are histologically squamous cell carcinomas (oral squamous cell carcinoma, OSCC). Combined with mucosal lip cancer, oral cavity cancer ranks as the 19th most common cancer globally, with approximately 390000 new cases and 190000 deaths annually. However, the burden of OSCC varies geographically, with Melanesia and South-Central Asia showing a much higher disease incidence. Despite advances in diagnostic and therapeutic approaches over recent decades, OSCC mortality has remained largely unchanged, with only approximately 55-60% of patients surviving 5 years after diagnosis. Tobacco use (both smoking and smokeless forms) and alcohol consumption are among the most important risk factors for OSCC. This book chapter aims to provide a general introduction to OSCC, including its epidemiology, associated etiological factors, a proposed model of molecular pathogenesis, the diagnostic pathway, common treatment modalities, and prognostic factors.",

Participants with concurrent plasma biomarkers, 3D T1-weighted MRI, and amyloid assessments were included. Logistic Regression, Decision Tree, and Support Vector Machine models were constructed using clinical, plasma, MRI, and combined features. Performance was evaluated via internal validation and external testing in a cognitively unimpaired cohort using AUC, calibration curves, and decision curve analysis. The prognostic value of the model-derived A\u03b2 risk probability was assessed using Cox regression in an independent longitudinal MCI cohort.ResultsThe optimal Logistic Regression model incorporated APOE \u03b54 status, Mini-Mental State Examination score, plasma p-Tau217, A\u03b242/A\u03b240 ratio, and bilateral hippocampal and left amygdalar volumes. The combined model achieved an AUC of 0.875 in internal validation and maintained robust performance in the external unimpaired cohort (AUC\u2009=\u20090.883), outperforming single-modality models. The predicted A\u03b2-positive risk probability effectively stratified disease progression risk in MCI patients (C-index\u2009=\u20090.771).ConclusionsA multimodal model integrating plasma and MRI features accurately predicts A\u03b2 pathology and progression risk, offering a practical non-invasive tool for early Alzheimer's disease screening and risk stratification.",

In the cell experiment, induced SH-SY5Y cells were pretreated with 3 \u03bcmol/L CHIR99021 for 2 h prior to MPP+ treatment. In a male C57BL/6 mouse model of MPTP-induced PD, the effect of intraperitoneal injection of CHIR99021 for 7 days on motor function of the mice were assessed using behavioral tests. Western blotting and immunofluorescence staining were used to detect the changes in the GSK-3\u03b2/NF-\u03baB pathway, NLRP3 inflammasome and autophagy in both SH-SY5Y cells and the mouse models. MPP+-treated SH-SY5Y cells showed significantly downregulated expression of p-GSK-3\u03b2 protein and upregulated expressions of p-NF-\u03baB p65, ASC, NLPR3, and caspase-1, and these changes were obviously attenuated by pretreatment with CHIR99021. Compared with normal mice, the PD mouse models showed significantly decreased motor function and reduced TH neurons in the brain with lowered expression of p-GSK-3\u03b2, increased expression of p-NF-\u03baB p65 (Ser536), and upregulated ASC, NLPR3, and caspase-1 expressions. Treatment with CHIR99021 significantly increased the expression of p-GSK-3\u03b2, and reduced the expression of p-NF\u2011\u03baB p65 (Ser536), ASC, NLPR3, and caspase-1. CHIR99021 inhibits the GSK-3\u03b2/NF\u2011\u03baB signaling pathway to improve motor function of PD mice, reduce neuroinflammation, and activate autophagy to maintain the homeostasis of intracellular environment, suggesting that targeting GSK-3\u03b2, a potential multifunctional therapeutic target, can simultaneously regulate multiple key pathological links in PD. \u76ee\u7684: \u63a2\u8ba8CHIR99021\u6291\u5236GSK-3\u03b2/NF-\u03baB\u901a\u8def\u6539\u5584\u5e15\u91d1\u68ee\u75c5\u795e\u7ecf\u708e\u75c7\u7684\u4f5c\u7528\u3002\u65b9\u6cd5: SH-SY5Y\u7ec6\u80de\u52a0\u51651-\u7532\u57fa-4-\u82ef\u57fa\u5421\u5576\uff08MPP+\uff09\uff081 mmol/L\uff09\u57f9\u517b24 h\uff0c\u6784\u5efaMPP-PD\u7ec6\u80de\u6a21\u578b\uff0c\u6cbb\u7597\u7ec4SH-SY5Y\u7ec6\u80de\u5148\u7ecfCHIR99021\uff083\u03bcmol/L\uff09\u9884\u5904\u74062 h\uff0c\u518d\u52a0\u5165MPP+\uff081 mmol/L\uff09\u57f9\u517b24 h\u3002\u5c06\u91ce\u751f\u578b\uff08WT\uff09\u5c0f\u9f20\u8fde\u7eed5 d\u8179\u8154\u6ce8\u5c041-\u7532\u57fa-4-\u82ef\u57fa-1\uff0c2\uff0c3\uff0c6-\u56db\u6c22\u5421\u5576\uff08MPTP\uff09\u6784\u5efaMPTP-PD\u52a8\u7269\u6a21\u578b\uff0c\u6cbb\u7597\u7ec4\u8fde\u7eed7 d\u8179\u8154\u6ce8\u5c04CHIR99021\uff0c\u4ece\u7b2c3\u5929\u5f00\u59cb\u95f4\u969412 h\u518d\u8179\u8154\u6ce8\u5c04MPTP\uff0c\u8fde\u7eed\u6ce8\u5c045 d\u3002\u4ee5WT\u578b\u5c0f\u9f20\u4f5c\u5bf9\u7167\uff0c\u901a\u8fc7\u65f7\u573a\u5b9e\u9a8c\u3001\u722c\u6746\u5b9e\u9a8c\u3001\u75b2\u52b3\u8f6c\u68d2\u5b9e\u9a8c\u8bc4\u4f30\u5404\u7ec4\u8fd0\u52a8\u884c\u4e3a\u80fd\u529b\u3002\u901a\u8fc7Western blotting \u548c\u514d\u75ab\u8367\u5149\u68c0\u6d4bCHIR99021\u5728\u4f53\u5185\u548c\u4f53\u5916\u6291\u5236GSK-3\u03b2/NF-\u03baB\u901a\u8def\u4fe1\u53f7\u8c03\u63a7NLRP3\u708e\u75c7\u5c0f\u4f53\u6fc0\u6d3b\u548c\u7ec6\u80de\u81ea\u566c\u6539\u5584\u5e15\u91d1\u68ee\u75c5\u795e\u7ecf\u708e\u75c7\u7684\u4f5c\u7528\u3002\u7ed3\u679c: \u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cMPP\u207a-PD\u7ec6\u80de\u6a21\u578b\u4e2d\uff0cp-GSK-3\u03b2 \uff08Ser9\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u4e0b\u8c03\uff08P<0.01\uff09\uff0c\u800c\u603bGSK-3\u03b2\u86cb\u767d\u91cf\u5dee\u5f02\u6ca1\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\u3002p-NF-\u03baB p65 \uff08Ser536\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u4e0a\u8c03\uff08P<0.01\uff09\uff0c\u800c\u603bNF-\u03baB p65 \uff08Ser536\uff09\u86cb\u767d\u91cf\u5dee\u5f02\u6ca1\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\u3002\u540c\u65f6ASC\u3001NLPR3\u3001Caspase-1\u708e\u75c7\u5c0f\u4f53\u8868\u8fbe\u4e0a\u8c03\uff08P<0.01\uff09\u3002\u800c\u5728MPP\u207a+CHIR99021\u7ec4\u4e2d\uff0cp-GSK-3\u03b2\u3001NF-\u03baB\u53ca\u708e\u75c7\u5c0f\u4f53\u86cb\u767d\u8868\u8fbe\u4e0b\u8c03.\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cMPTP-PD\u5c0f\u9f20\u6a21\u578b\u4e2d\uff0c\u5c0f\u9f20\u8fd0\u52a8\u529f\u80fd\u4e0b\u964d\uff08P<0.001\uff09\uff0c\u8111\u5185TH\u795e\u7ecf\u5143\u51cf\u5c11\uff08P<0.01\uff09\u3002\u9ed1\u8d28\u90e8\u4f4d\u7684p-GSK-3\u03b2 \uff08Ser9\uff09\u6c34\u5e73\u540c\u6837\u964d\u4f4e\uff08P<0.01\uff09\uff0c\u603bGSK-3\u03b2\u86cb\u767d\u91cf\u53d8\u5316\u5dee\u5f02\u65e0\u7edf\u8ba1\u5b66\u610f\u4e49\u3002\u800cp-NF-\u03baB p65 \uff08Ser536\uff09\u6c34\u5e73\u540c\u6837\u663e\u8457\u5347\u9ad8\uff08P<0.01\uff09\uff0c\u603bNF-\u03baB p65\u86cb\u767d\u91cf\u8868\u8fbe\u53d8\u5316\u5dee\u5f02\u65e0\u7edf\u8ba1\u5b66\u610f\u4e49\uff0cASC\u3001NLPR3\u3001Caspase-1\u708e\u75c7\u5c0f\u4f53\u8868\u8fbe\u4e0a\u8c03\uff08P<0.01\uff09\u3002\u800cMPTP-CHIR99021\u7ec4\u8f83MPTP-PD\u7ec4\u76f8\u6bd4\uff0cp-GSK-3\u03b2\u3001NF-\u03baB\u53ca\u708e\u75c7\u5c0f\u4f53\u86cb\u767d\u8868\u8fbe\u4e0b\u8c03\uff08P<0.01\uff09\u3002\u7ed3\u8bba: CHIR99021\u901a\u8fc7\u6291\u5236GSK-3\u03b2/NF-\u03baB\u4fe1\u53f7\u901a\u8def\uff0c\u663e\u8457\u6539\u5584\u5e15\u91d1\u68ee\u75c5\uff08PD\uff09\u5c0f\u9f20\u7684\u8fd0\u52a8\u529f\u80fd\uff0c\u51cf\u8f7b\u795e\u7ecf\u708e\u75c7\uff0c\u5e76\u6fc0\u6d3b\u7ec6\u80de\u81ea\u566c\u4ee5\u7ef4\u6301\u7ec6\u80de\u5185\u73af\u5883\u7a33\u6001\u3002\u9776\u5411GSK-3\u03b2\u53ef\u540c\u65f6\u8c03\u63a7PD\u591a\u4e2a\u5173\u952e\u75c5\u7406\u73af\u8282\uff0c\u5177\u6709\u4f5c\u4e3a\u591a\u529f\u80fd\u6cbb\u7597\u9776\u70b9\u7684\u6f5c\u529b\u3002.",

Cultured RAW264.7 cells were pretreated with, different concentrations of BBP, or dexamethasone (Dex) for 1 h before LPS challenge. Sixty male C57BL/6 mice were randomized into 5 groups (n=12), including a control group, a LPS-induced ALI model group, a Dex treatment group, and two BBP treatment groups treated with low- (30 mg/kg) or high-dose (120 mg/kg) BBP. The levels of inflammatory factors and oxidative stress-related indicators in the cells and mouse lung tissues were determined, and mouse lung histopathology, wet/dry weight ratio, and BALF cell count were examined; the expressions of NF-\u03baB and Nrf-2/HO-1 pathways were detected using qPCR, Western blotting, and immunohistochemistry. In LPS-stimulated RAW264.7 cells, BBP (12.5 \u03bcg/mL) significantly reduced the levels of TNF-\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, NO and ROS, enhanced SOD activity, increased mRNA expressions of I\u03baB-\u03b1, Nrf-2, and HO-1, and lowered mRNA expressions of TNF-\u03b1, IL-1\u03b2, Keap-1, and NF-\u03baB (p65). The ALI mouse models showed severe lung pathologies and edema, increased BALF cell counts, and increased levels of TNF\u2011\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, and NO, lowered SOD activity with reduced protein expressions of I\u03baB-\u03b1, Nrf-2, and HO-1 and increased expressions of Keap-1 and p65. Treatment with high-dose BBP significantly ameliorated lung pathologies in the mouse models and improved the aberrant alterations in pulmonary expressions of inflammatory factors, oxidative stress-related indicators and the NF-\u03baB and Nrf-2/HO-1 pathways. BBP protects against LPS-induced ALI in mice possibly by targeting the Nrf-2/HO-1 and NF-\u03baB pathways, suggesting its potential as a therapeutic agent for ALI. \u76ee\u7684: \u63a2\u7a76\u718a\u80c6\u7c89\uff08BBP\uff09\u901a\u8fc7\u8c03\u63a7NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u5bf9\u8102\u591a\u7cd6\u8bf1\u5bfc\u7684\u6025\u6027\u80ba\u635f\u4f24\uff08ALI\uff09\u5c0f\u9f20\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u4f53\u5916\u5b9e\u9a8c:\u91c7\u7528\u8102\u591a\u7cd6\uff08LPS\uff09\u8bf1\u5bfcRAW264.7\u7ec6\u80de\u5efa\u7acb\u4f53\u5916\u6a21\u578b\uff0c\u8bbe\u7f6e\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001\u5730\u585e\u7c73\u677e\uff08Dex\uff0c25 \u03bcg/mL\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff086.25 \u03bcg/mL\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff0812.5 \u03bcg/mL\uff09\u3002\u4f53\u5185\u5b9e\u9a8c:\u5c0660\u53eaC57BL/6\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001Dex\u7ec4\uff085 mg/kg\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff0830 mg/kg\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff08120 mg/kg\uff09\uff0c12\u53ea/\u7ec4\u3002\u901a\u8fc7ELISA\u548c\u76f8\u5173\u8bd5\u5242\u76d2\u68c0\u6d4b\u7ec6\u80de\u548c\u80ba\u7ec4\u7ec7\u4e2d\u708e\u75c7\u4e0e\u6c27\u5316\u5e94\u6fc0\u6307\u6807;\u901a\u8fc7\u80ba\u7ec4\u7ec7\u75c5\u7406\u5206\u6790\u3001\u514d\u75ab\u7ec6\u80de\u8ba1\u6570\u548c\u80ba\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u7b49\u6307\u6807\u8bc4\u4ef7BBP\u5bf9ALI\u7684\u5e72\u9884\u4f5c\u7528\u3002\u901a\u8fc7qRT-PCR\u3001Western blotting\u548c\u514d\u75ab\u7ec4\u5316\u6cd5\u5206\u6790NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u76f8\u5173\u86cb\u767d\u4e0e\u57fa\u56e0\u7684\u8868\u8fbe\u53d8\u5316\u3002\u7ed3\u679c: \u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\u7ec4\uff0812.5\u03bcg/mL\uff09\u663e\u8457\u964d\u4f4eTNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u4e00\u6c27\u5316\u6c2e\uff08NO\uff09\u548c\u6d3b\u6027\u6c27\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff0c\u4e14I\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff0c\u800cTNF-\u03b1\u3001IL-1\u03b2\u3001Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff08P<0.05\uff0cP<0.01\uff0cP<0.001\uff09\u3002\u52a8\u7269\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u7ed3\u6784\u7d0a\u4e71\uff0c\u80ba\u6ce1\u58c1\u589e\u539a\uff0c\u80ba\u6ce1\u5185\u53ef\u89c1\u5927\u91cf\u708e\u75c7\u7ec6\u80de\u6d78\u6da6\uff0c\u80ba\u7ec4\u7ec7\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u53ca\u652f\u6c14\u7ba1\u80ba\u6ce1\u704c\u6d17\u6db2\uff08BALF\uff09\u603b\u7ec6\u80de\u6570\u5347\u9ad8\uff08P<0.01\uff09;\u80ba\u7ec4\u7ec7\u4e2d\u7684TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u542b\u91cf\u5347\u9ad8\uff0c\u800cSOD\u6d53\u5ea6\u964d\u4f4e\uff08P<0.01\uff0cP<0.001\uff09;\u4e14\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff0cKeap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\uff08120 mg/kg\uff09\u7ec4\u80fd\u6539\u5584\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u75c5\u7406\u635f\u4f24\u72b6\u6001\uff0c\u6539\u5584\u80ba\u80bf\u80c0\u7a0b\u5ea6\uff0c\u964d\u4f4eBALF\u603b\u7ec6\u80de\u6570\u3001TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09;\u540c\u65f6\uff0cBBP\u4e0a\u8c03\u4e86\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u5e76\u6291\u5236\u4e86Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09\u3002\u7ed3\u8bba: BBP\u53ef\u80fd\u901a\u8fc7\u4f5c\u7528\u4e8eNrf-2/HO-1\u548cNF-\u03baB\u4fe1\u53f7\u901a\u8def\u5bf9LPS\u8bf1\u5bfc\u7684ALI\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u540e\u7eed\u7814\u7a76\u6f5c\u5728\u7684\u6cbb\u7597ALI\u836f\u7269\u63d0\u4f9b\u4f9d\u636e\u3002.",
        "42486854": "ID: 42486854\nTitle: Loss of Atp8a2 drives neurodegeneration through the dysregulation of spatiotemporal phosphatidylserine externalization in mature neurons.\nAbstract: Phosphatidylserine (PS) asymmetry in plasma membranes is critical for cellular functions and serves as an apoptotic signal in many cell types. However, in mature neurons, the molecular mechanisms governing PS distribution, its precise regulation, and its functional significance beyond apoptosis and development remain poorly understood - particularly in the context of neurodegeneration. Here, we mapped the spatiotemporal dynamics of PS exposure in mature hippocampal neurons under physiological and pathological conditions using time-lapse imaging, revealing specific PS externalization hotspots at dendritic branching points. Using multiple in vitro and in vivo neurodegeneration models combined with molecular modeling, RNA interference, pharmacological interventions, and biochemical assays, we identified Atp8a2 as the primary regulator of PS asymmetry in mature neurons beyond its known roles in development. Notably, Atp8a2 expression levels - rather than its flippase activity alone - were essential for maintaining neuronal structural integrity and viability. Atp8a2 expression was significantly altered by neurotoxic stimuli and in multiple mouse models of neurodegeneration. Reduced Atp8a2 expression led to increased PS exposure, compromised neuronal architecture, and heightened susceptibility to degeneration, whereas Atp8a2 overexpression conferred substantial neuroprotection. The distinction between Atp8a2's enzymatic activity and expression level reveals a mechanism of neuronal homeostasis linking PS regulation to structural integrity and survival, possibly through association with cytoskeletal protein networks. Thus, Atp8a2 expression is a critical determinant of mature neuronal viability, presenting a potential target for neuroprotective strategies in neurodegeneration.",

However, implementation in primary care and community settings remains limited. Building dementia-prepared health systems requires scalable and adaptive pathways that integrate subjective, digital and biological indicators, while accounting for heterogeneity in risk,\u00a0education and age. CogScreen I was a cluster-randomized trial conducted in Munich senior centers from March 2023 to March 2024. Recruitment focused on community-dwelling adults aged\u2009\u2265\u200960\u00a0years reporting subjective cognitive concerns. Centers were randomized to: (A) the Subjective Cognitive Decline Questionnaire\u00a0(SCD-Q) only, (B) SCD-Q plus digital cognitive testing, or (C) SCD-Q plus digital testing plus blood biomarkers (A\u03b21-42/1-40, pTau181, GFAP, NfL). The primary endpoints were feasibility and acceptability, assessed through structured questionnaires and follow-up interviews with participants and general practitioners. Secondary endpoints examined latent cognitive structures and biomarker associations. Exploratory factor and clustering analyses revealed multimodal subgroups across subjective, digital, and biological measures, which informed a hypothesis-generating three-tier adaptive detection framework (low, medium, high intensity). Among the 473 participants (mean age 74.1\u2009\u00b1\u20097.6\u00a0years; 66% female; 63% with tertiary education), both feasibility and acceptability were high: Participants described the assessments as personally relevant, clearly communicated, and medically meaningful, and appreciated the added value of digital testing and biomarkers. Digital cognitive testing and biomarkers captured distinct latent dimensions of learning/working memory, psychomotor attention, and glial and amyloid pathology. Exploratory multimodal clustering identified three dementia risk profiles-low concern, intermediate, and at risk-which informed an adaptive, tiered detection model. Notably, subjective cognitive concerns assessed by the SCD-Q were strongly associated with overall subjective symptom burden, supporting the use of brief self-report questionnaires as a pragmatic and scalable first-step stratification approach in community-based dementia detection. Community-based, tiered detection pathways for cognitive decline are feasible, acceptable, and meaningful to older adults. Exploratory multimodal profiling suggests that combining subjective, digital, and biological measures may support individualized assessment strategies. However, limited GP engagement highlights the need for stronger integration with primary care to ensure downstream diagnostics and prevention pathways. The proposed framework remains hypothesis-generating and requires prospective validation.Clinical trials registeredCogScreen has been registered at clinical trials (NCT06191952, 2023-12-20).",
        "42486997": "ID: 42486997\nTitle: Peripheral blood inflammatory biomarkers and response to vagus nerve stimulation in pediatric drug-resistant epilepsy: A retrospective cohort study.\nAbstract: Vagus Nerve Stimulation (VNS) is an established treatment for drug-resistant epilepsy (DRE) in children, but response rates vary significantly (50%-60%). Given that neuroinflammation is implicated in epilepsy and VNS may modulate systemic inflammation, this study explored associative links between routine blood inflammatory indices and VNS treatment response in pediatric DRE. We retrospectively analyzed 108 pediatric DRE patients who received VNS. Six peripheral inflammatory indices, namely neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammatory response index (SIRI), and pan-immune-inflammation value (PIV), were calculated at preoperative and post-titration 12\u00a0months. We used Multivariable Regression and Latent Change Score Models (LCSM) to assess the impact of baseline status and dynamic postoperative changes. Multivariable analyses revealed associations between inflammatory indices and VNS outcomes. The LCSM demonstrated that the associative roles of these indices were temporally distinct: VNS response showed significant correlations with the magnitude of postoperative change in Lymphocyte count (beta\u2009=\u2009\u2009-\u20090.73, p\u2009<\u20090.01), NLR (beta\u2009=\u20090.69, p\u2009<\u20090.01), and SIRI (beta\u2009=\u20090.75, p\u2009<\u20090.01), independent of baseline status. Conversely, the associative patterns of PIV and SII were primarily related to their initial baseline levels. \u00a0The efficacy of VNS in pediatric DRE is associated with systemic inflammatory dynamics. Postoperative changes in these inflammatory indices are associated with VNS treatment outcomes and may serve as a potential prognostic indicator for clinical response. \u2022 Vagus nerve stimulation (VNS) is an effective therapy for pediatric drug-resistant epilepsy (DRE), yet treatment response varies markedly across individuals. \u2022 Neuroinflammation is involved in epileptogenesis, and VNS may exert antiseizure effects via modulating systemic inflammation. \u2022 Peripheral inflammatory indices are easily accessible but their associative links with VNS response remain unclear. \u2022 This study first demonstrates that preoperative and postoperative dynamic changes in peripheral inflammatory biomarkers independently associate with VNS efficacy in children. \u2022 Latent change score modeling reveals that postoperative reductions in neutrophil-to-lymphocyte ratio (NLR) and systemic inflammatory response index (SIRI) correlate with favorable seizure outcomes, while baseline systemic immune-inflammation index (SII) and pan-immune-inflammation value (PIV) levels help identify favorable candidates. \u2022 These low-cost peripheral indices display correlative links with treatment outcomes and may provide preliminary reference information for auxiliary stratification and serial follow-up monitoring.",
        "42487016": "ID: 42487016\nTitle: Hypoxia as an amplifier of synovial inflammation in rheumatoid arthritis.\nAbstract: Inflammatory arthritis is characterized by neovascularization, leukocyte extravasation and synovial hyperplasia, leading to joint destruction and functional disability. Although increased synovial angiogenesis is a hallmark of synovial inflammation, efficiency of the oxygen supply to the synovium is poor, leading to a hypoxic gradient that impacts differential cellular responses. This hypoxic gradient occurs as infiltrating cells and cells that reside within the joint increase their metabolic demand beyond what the highly dysregulated vasculature can supply. This hypoxic environment favours an increase in reactive oxygen species, leading to oxidative damage that further promotes inflammation. In this adverse microenvironment, synovial cells adapt to generate energy and switch their cellular metabolism from a resting regulatory state to a highly metabolically active state, enabling them to produce essential building blocks to support their proliferation. This metabolic shift results in the accumulation of metabolic intermediates that function as signalling molecules, which further dictate the inflammatory response. However, the synovium is a complex multicellular tissue, and the specific cellular reliance on oxygen and metabolites differs across the synovium. Cellular demands depend on anatomical location, cell-cell interactions and competition for nutrients. Understanding the complex interplay between hypoxia-induced signalling pathways, oxidative stress and inflammatory responses will provide a better insight into the underlying mechanisms of disease pathogenesis.",

This study aimed to investigate the synergistic effects of bone marrow mesenchymal stem cells (BMSC)-derived exosomal METTL3 and Sevoflurane (Sev) in alleviating pulmonary I/R injury through ferroptosis regulation. In our study, pulmonary I/R injury models were established in mice and lung microvascular endothelial cells (LMECs). Commercial kits were used to measure myeloperoxidase (MPO), glutathione (GSH), malondialdehyde (MDA), and iron content. Lipid peroxidation was determined using the BODIPY 581/591 C11 probe by flow cytometry. Total m6A modification was measured by the commercial kit and m6A dot blot, while m6A modification of USP7 mRNA was analyzed by MeRIP and polysome profiling. The interaction between proteins or RNAs was analyzed by Co-IP, FISH combined with immunofluorescence, RNA pull-down, RIP, or dual-luciferase reporter assay. We proved Sev preconditioning mitigated ferroptosis in pulmonary I/R injury by activating the Nrf2 pathway. Co-treatment with BMSC-derived exosomes potentiated the protective effects of Sev by promoting USP7-mediated Nrf2 deubiquitination modification. Mechanistically, BMSC-derived exosomal METTL3 promoted USP7 mRNA translation through YTHDC2-dependent m6A modification. Also, METTL3 knockdown in exosomes suppressed the Nrf2 pathway and exacerbated ferroptosis, while METTL3 overexpression showed opposite effects. YTHDC2 knockdown abolished these protective effects caused by METTL3-overexpressed exosomes. In conclusion, BMSC-derived exosomal METTL3 reinforced the protective effects of Sev by promoting USP7 mRNA translation via YTHDC2-dependent m6A modification. Upregulated USP7 subsequently facilitated Nrf2 deubiquitination, thereby inhibiting ferroptosis and protecting against pulmonary I/R injury.",
        "42487073": "ID: 42487073\nTitle: Immunomodulatory effects of ultrasonically lysed Bifidobacterium breve on Pam3CSK4-stimulated J774A.1 macrophages via SIRT1/NRF2 activation and NF-\u03baB suppression.\nAbstract: Bacterial lysates, which contain cell wall components and intracellular metabolites, have emerged as important modulators of macrophage immune function through interactions with pattern recognition receptors (PRRs). Ultrasonication is an effective technique for extracting these bioactive constituents. The goal of this work was to examine the immunomodulatory and cytoprotective effects of ultrasonically lysed Bifidobacterium breve (BB-UL) in J774A.1 macrophages activated by Pam3CSK4. J774A.1 macrophages were pre-exposed to BB-UL (equivalent to 10\u2078 CFU/mL) for 12\u00a0h before stimulation with Pam3CSK4 (500 ng/mL). Cell viability was determined via the MTT assay, intracellular reactive oxygen species (ROS) were quantified using the DCFDA assay, and apoptosis was assessed with Annexin V-FITC/PI staining. Gene expression levels of Sirt1, Nfe2l2, Hmox1, Rela, Il1b, Il6, Tnf, Bax, and Bcl2 were analyzed by RT-qPCR, while secreted cytokines were measured using ELISA. Statistical significance was evaluated using one-way ANOVA followed by Tukey's post hoc test (n\u2009=\u20093). Pam3CSK4 exposure significantly decreased cell viability to approximately 50% of control levels, whereas BB-UL pretreatment restored viability to around 80-85% (p\u2009<\u20090.01 vs. Pam3CSK4), indicating a protective effect. Pam3CSK4 also induced a substantial increase in intracellular ROS (~\u20093-fold vs. control), which was reduced by approximately 40% following BB-UL treatment (p\u2009<\u20090.05-0.01). Similarly, late apoptosis increased from ~\u20093-4% in control cells to ~\u200915% upon stimulation, while BB-UL pretreatment decreased this value to approximately 8% (p\u2009<\u20090.01). At the molecular level, Pam3CSK4 downregulated Sirt1 (~\u20090.5-fold) and Nfe2l2 (~\u20090.55-fold), while upregulating Rela (~\u20092.5-fold). BB-UL partially restored Sirt1 (~\u20090.7-fold) and Nfe2l2 (~\u20090.75-fold) expression and reduced NF-\u03baB activation (~\u20091.8-fold vs. control, p\u2009<\u20090.05). Additionally, BB-UL increased Hmox1 expression (~\u20090.9-fold) and favorably regulated apoptosis-related genes by decreasing Bax (~\u20091.5-fold) and increasing Bcl2 (~\u20090.8-fold), thereby improving the Bax/Bcl2 ratio. Following BB-UL pretreatment, elevated levels of pro-inflammatory cytokines (Il1b, Il6, and Tnf) caused by Pam3CSK4 were considerably decreased at both gene and protein levels (p\u2009<\u20090.05-0.01). In Pam3CSK4-stimulated macrophages, ultrasonically lysed B. breve had notable cytoprotective, antioxidant, and anti-inflammatory properties. Reduced oxidative stress, apoptosis, and inflammatory cytokine production were associated with modulation of SIRT1, NRF2, HO-1, and NF-\u03baB-related gene expression. These findings suggest that BB-UL may represent a promising postbiotic candidate for modulating macrophage-mediated inflammatory responses.",

The underlying toxic mechanisms in earthworms remain unclear, but research highlights coelomocytes and catalase (CAT) as crucial for studying its cytotoxic and proteotoxic effects. 1,4-NQ caused cell membrane damage, mitochondrial injury, and oxidative stress. Studies using spectroscopy, isothermal titration calorimetry, and molecular simulation revealed that 1,4-NQ increased cell membrane permeability, indicated by higher LDH release and decreased Na+K+-ATPase activity, leading to dose-dependent cytotoxicity. It also induced oxidative damage via ROS production, impacting MDA levels, mitochondrial function, membrane potential, and intracellular calcium. Additionally, 1,4-NQ weakened antioxidant defenses, affecting CAT activity and GSH levels. It interacted with CAT, altering its structure to decrease hydrophobicity and loosen its framework, which exposed the catalytic site for better interaction with H2O2. Consequently, 1,4-NQ directly activated CAT, reducing free radicals and oxidative damage in coelomocytes. While CAT activity increased at the molecular level, an overall inhibition was observed in coelomocytes, suggesting that cellular oxidative stress counteracted the direct molecular activation through unknown mechanisms that warrant further investigation.",

There were time effects for the activity of citrate synthase and mitochondrial enzyme complexes I and IV (P\u00a0<\u00a00.05) and the protein abundance of p-AMPK (P\u00a0<\u00a00.05) in muscle after training. These responses did not differ between the CWI and ACT groups. Evaluation of muscle oxidative capacity using near-infrared spectroscopy showed slower oxygen desaturation during a 10\u00a0s isometric contraction, and greater oxygen consumption during 50 isokinetic contractions after training in the CWI group (P\u00a0<\u00a00.05). In conclusion, CWI after resistance exercise does not alter acute redox-related transcription or chronic mitochondrial adaptations, whereas it might improve muscle oxygen kinetics.",

Yougui Pills (YGPs), a classical traditional Chinese medicine formula, are widely applied in clinical OP management, yet the cellular and molecular mechanisms underlying their anti-osteoporotic effects remain incompletely defined. This study aimed to elucidate the bone-protective role of YGPs in OP and explore the underlying mechanism, focusing on oxidative stress modulation in MSCs and the Nrf2/HO-1 signalling pathway. The bioactive components of YGPs and YGP-containing serum were characterized via UPLC. In vivo, an ovariectomy (OVX) mouse model was established to evaluate YGPs' effects on bone mass, trabecular microstructure and osteogenesis using micro-CT, histological and immunohistochemical assays; public GEO datasets were re-analysed to profile transcriptomic alterations and oxidative stress signatures in OP-derived MSCs. In vitro, H2O2 was used to induce ROS accumulation and oxidative injury in MSCs, with assessments of cell proliferation, apoptosis, ROS levels, migration and osteogenic differentiation. Network pharmacology and siRNA-mediated gene silencing were conducted for target prediction and mechanistic validation. In vivo results showed that YGP treatment significantly ameliorated OVX-induced osteopenia, increased bone mineral density, improved trabecular microstructure, and upregulated osteogenic markers (ALP, OCN, Runx2, COL1A1). Transcriptomic re-analysis revealed upregulated oxidative stress markers in OP MSCs, consistent with In vitro findings that YGPs attenuated H2O2-triggered ROS overproduction, suppressed apoptosis and ectopic lipid deposition, and enhanced MSC proliferation, migration and osteogenic differentiation. Mechanistically, YGPs activated the Nrf2/HO-1 signalling axis, while Nrf2 knockdown abrogated YGPs' cytoprotective and pro-osteogenic effects. In conclusion, YGPs mitigate oxidative stress-induced MSC dysfunction and promote osteogenesis via the Nrf2/HO-1 pathway, supporting YGPs as a promising therapeutic candidate for OP.",

This narrative review examines whether a categorical distinction between iPD and \"toxic parkinsonism\" is defensible on diagnostic, pathological, neuroimaging, epidemiological, causal-inference, and legal grounds. The 2024 NSD-ISS (Neuronal \u03b1-synuclein disease Integrated Staging System) and SynNeurGe (Synuclein-Neurodegeneration-Gene) frameworks challenge categorical use of the \"idiopathic\" label by defining Parkinson's disease (PD)-related disease biologically, irrespective of etiology. Nonhuman primate studies show that chronic low-dose manganese exposure can produce nigrostriatal deficits and \u03b1-synuclein aggregation overlapping with PD biology. Dichotomous use of FP-CIT dopamine transporter imaging or levodopa responsiveness to separate manganese poisoning from iPD is therefore scientifically unsound, as chronic welding exposure can induce presynaptic dysfunction and treatment responses indistinguishable from PD. Epidemiological findings diverge methodologically: direct clinical examination has reported elevated parkinsonism prevalence among welders, whereas administrative cohorts have generally found no increased PD risk. This divergence is plausibly explained by differences in case ascertainment, exposure assessment, healthy-worker-survivor selection, and disease latency. Bradford Hill and Rothman frameworks support a causal interpretation, although validated biomarkers and dose-response thresholds remain undefined. Under Korea's Industrial Accident Compensation Insurance Act, causation is evaluated as a \"proximate causal relationship\" rather than strict scientific proof. A multi-hit model integrating genetic predisposition, aging, and cumulative environmental exposure supports recognition under this standard, and compensation eligibility should not depend on whether the diagnosis label is 'PD' or 'parkinsonism.' When parkinsonian symptoms occur in welders with at least approximately 20,000 exposure-weighted welding hours, or with substantial high-intensity exposure such as confined-space welding, inadequate ventilation, or flux-cored arc welding, occupational contribution should be considered under a weight-of-evidence approach. This criterion is sufficient for recognition but is not a necessary condition.",

In this study, serum miR-199a-5p levels were markedly elevated in AMI patients and positively correlated with myocardial injury markers cardiac troponin I and creatine kinase-MB, while H/R stimulation similarly upregulated miR-199a-5p expression in AC16 cardiomyocytes. Functional experiments demonstrated that miR-199a-5p overexpression exacerbated oxidative stress and ferroptosis, as evidenced by increased lactate dehydrogenase release, malondialdehyde production, Fe\u00b2+ accumulation, lipid peroxidation, and glutathione depletion, whereas miR-199a-5p inhibition conferred significant protection against H/R-induced injury. Mechanistically, heat shock protein \u03b2\u20111 (HSPB1) was identified as a direct downstream target of miR-199a-5p, with HSPB1 overexpression alleviating and its silencing aggravating ferroptotic responses under H/R conditions. Rescue assays further confirmed that HSPB1 mediates the pro-ferroptotic effects of miR-199a-5p. At the molecular level, the miR-199a-5p/HSPB1 axis regulated key ferroptosis-related proteins, including ACSL4, SLC7A11, and GPX4, and disrupted Keap1/Nrf2/ARE antioxidant signaling during H/R injury. Collectively, these findings indicate that miR-199a-5p aggravates H/R-induced cardiomyocyte ferroptosis by suppressing HSPB1 and impairing Nrf2-dependent antioxidant defense, suggesting that circulating miR-199a-5p may serve as a biomarker of myocardial injury and a potential therapeutic target in ischemic heart disease.",

A cationic bovine serum albumin (cBSA)-induced mouse model of MN was established, followed by PM2.5 exposure. Renal injury was assessed using hematological indicators, hematoxylin-eosin staining, and periodic acid-Schiff staining. Levels of inflammatory factors and ferroptosis indicators were assessed by enzyme-linked immunosorbent assay and western blot. An in\u00a0vitro MN-like model was created by stimulating differentiated MPC5 podocytes with puromycin aminonucleoside (PAN), followed by PM2.5 treatment. DNA methylation levels were determined using quantitative methylation-specific polymerase chain reaction. Podocytes were pretreated with GKT137831 or ferrostatin-1 for in\u00a0vitro rescue experiments. PM2.5 exposure significantly aggravated renal injury in cBSA-induced MN mice, as indicated by increased levels of urinary total protein, serum creatinine, and blood urea nitrogen; the deposition of IgG and C3; and histopathological alterations. Furthermore, PM2.5 increased levels of ferroptosis and inflammation in the renal tissues of cBSA-induced MN mice, accompanied by the activation of the NOX4/NRF2 axis. In PAN and PM2.5 co-treated MPC5 cells, NOX4 expression was elevated, whereas its methylation level was reduced. Overexpression of DNMT1 reversed the PM2.5-induced suppression of NOX4 methylation. Notably, pretreatment with GKT137831 or ferrostatin-1 attenuated the PM2.5-mediated reduction in cell viability and prevented the activation of ferroptosis and pro-inflammatory phenotypes in PAN-stimulated MPC5 cells. In conclusion, PM2.5 promotes ferroptosis and inflammation through an epigenetically regulated NOX4/NRF2 axis, thereby exacerbating renal injury in MN.",

Agardhiella subulata extracts are known for their antioxidant and hepatoprotective properties, yet their effects against DEHP-induced testicular toxicity remain unclear. This study investigated the extraction, characterization, and protective effects of A. subulata sulfated polysaccharide (ASP) against DEHP-induced testicular damage. Autoclave-assisted extraction yielded 40.4% ASP. Chemical and structural characterization using HPLC and NMR identified ASP as a sulfated carrageenan predominantly composed of \u03b2-Gal4S and DA2S, with minor impurities. In mice exposed to DEHP (200\u00a0mg/kg/day) for 10 weeks, ASP treatment (50 or 200\u00a0mg/kg/day via oral gavage) significantly improved testicular weight, sperm count, and motility, while alleviating seminiferous tubule atrophy and germinal epithelium degeneration. ASP attenuated oxidative stress by normalizing MDA, SOD, and GSH levels. Mechanistically, ASP activated the Nrf2/HO-1 antioxidant signaling pathway, suppressed caspase-3 and caspase-8 expression, reduced inflammation, and enhanced steroidogenesis by increasing stAR and 3\u03b2-HSD expression and serum testosterone levels. Overall, these findings demonstrate that ASP effectively mitigated DEHP-induced testicular toxicity through antioxidant, anti-apoptotic, anti-inflammatory, and steroidogenic mechanisms. These findings suggest that ASP is a promising natural agent for protecting against DEHP-induced reproductive toxicity and improving testicular function. Thereby supporting SDG goals 3, 12, and 15.",

However, the precise mechanisms underlying depression in epilepsy remain unclear. This review synthesizes the latest research on the pathogenesis of depression in epilepsy, focusing on abnormalities in monoamine neurotransmitters, neuroinflammation, HypothalamicPituitary-Adrenal (HPA) axis dysfunction, neurotrophic factors, mitochondrial dysfunction, and oxidative stress. The article explores the dual roles of antidepressants and antiepileptic drugs (AEDs) in the treatment of depression in epilepsy, highlighting drugs that may exacerbate either depression or seizure activity. The need for more nuanced treatment strategies, including the careful selection of antidepressants and AEDs, is emphasized. Additionally, non-drug interventions, such as Cognitive-Behavioral Therapy (CBT), neuromodulation techniques, and dietary modifications (anti-inflammatory and antioxidant foods), are reviewed as vital adjuncts to pharmacological treatments. This article aims to guide clinicians in choosing optimal treatment strategies and underscores the importance of timely depression screening, long-term management, and personalized therapy for patients with epilepsy and comorbid depression.",

Ferroptosis and mitochondrial biogenesis indicators were measured at various time points following MCAO. Various methods, including transmission electron microscopy, immunofluorescence assay, enzyme-linked immunosorbent assay, Western blotting assays, and real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR), were employed to evaluate the impact of NTF on mitochondrial biogenesis and ferroptosis in vivo and in vitro. IS significantly inhibits mitochondrial biogenesis and increases neuronal ferroptosis, with brain damage worsening over time. MCAO groups showed reduced expression of Nrf2, TFAM, ATP, CISD2, FPN, GPX4, SOD, and HO-1, alongside elevated Fe\u00b2\u207a, ROS, and LPO (P < 0.05) compared to the control group. Both sulforaphane and NTF treatment reversed these effects; NTF treatment effectively increased the expression of Nrf2, TFAM, FtMt, CISD1, CISD2, FPN, and GPX4 while inhibiting the levels of Fe2+, ROS, and LPO. (P < 0.05). This finding clarifies mitochondrial biogenesis's crucial role, proposes a new \"pathway + molecule\" strategy for IS treatment, and supports NTF's clinical potential, though larger animal models and long-term safety studies are needed. In the context of IS, reduced mitochondrial biogenesis plays an important role in ferroptosis. Targeting the Nrf2/TFAM signaling pathway may improve mitochondrial biogenesis in IS. Furthermore, NTF can mitigate ferroptosis by promoting mitochondrial biogenesis through the Nrf2/TFAM signaling pathway.",

However, its clinical utility is hindered by poor aqueous solubility and low bioavailability. To address these limitations, Curcumin-loaded Solid Self-Emulsifying Drug Delivery Systems (C-SSEDDS) have been formulated to improve pharmacokinetics and neuronal targeting. Despite these advancements, the molecular mechanisms underlying curcumin in Alzheimer's Disease (AD)-related neuronal senescence remain poorly understood. Therefore, this study provides novel molecular insights into the therapeutic potential of C-SSEDDS for targeting neuronal senescence- like features in the AD context. An in vitro model of neuronal senescence-like features was established by exposing SK-N-SH cells to 0.075 \u03bcM A\u03b225-35 for 24 hours, resulting in a 20-30% decline in cell viability. Subsequently, cells were post-treated with C-SSEDDS at optimized non-toxic concentrations (0.1, 1, and 10 \u03bcg/mL curcumin equivalent) and 10 \u03bcg/mL commercial curcumin for 24, 48, and 72 hours in A\u03b225-35-free media. The study comprehensively assessed cell viability, morphological alterations, and key biomarkers associated with neuronal senescence-like features, including senescence- associated beta-galactosidase (SA-\u03b2-gal) positive cells, Reactive Oxygen Species (ROS) levels, NLRP3, Sirt-1, and synaptophysin expression. C-SSEDDS post-treatment significantly improved cell viability, reduced apoptotic cells, and decreased SA-\u03b2-gal positive cells in A\u03b225-35-induced senescence-like SK-N-SH cells compared to the untreated A\u03b225-35 group. It also effectively decreased intracellular ROS level and NLRP3 expression, and markedly upregulated Sirt-1 and synaptophysin expression. Notably, CSSEDDS demonstrated therapeutic efficacy superior to commercial curcumin and comparable to N-acetylcysteine (NAC). In SK-N-SH cells exhibiting senescence-like features, the C-SSEDDS formulation effectively counteracts A\u03b225-35-induced damage. It mitigates key drivers of cellular stress, including oxidative stress, inflammation-related markers, and apoptosis, while also enhancing Sirt-1 activity and promoting synaptic plasticity. C-SSEDDS demonstrates significant potential as a promising therapeutic strategy against A\u03b225-35 -induced neuronal stress and senescence-like changes in AD.",

Microglia-specific overexpression of Sestrin2 was achieved by injecting adeno-associated virus (AAV) into the CUS mouse hippocampus. Depressive-like behaviors were assessed using sucrose preference, tail suspension, and forced swim tests. Cognitive function was evaluated by the Morris water maze. Levels of IL-1\u03b2 and IL-6 in the hippocampus and cell supernatants were measured by ELISA. BV2 microglial cells were used for in vitro mechanistic studies. YTHDF1 siRNA and overexpressive lentivirus were used to regulate YTHDF1 expression in vitro. RNA immunoprecipitation was performed to demonstrate the physical interaction between YTHDF1 and Sestrin2 mRNA. Sestrin2 expression was significantly reduced in the hippocampus of CUS mice. Overexpression of Sestrin2 specifically in microglia ameliorated CUS-induced depressive-like behaviors, cognitive impairment, and inflammatory levels. YTHDF1 expression was also reduced in the CUS hippocampus. Mechanistically, YTHDF1 bound to Sestrin2 mRNA and knockdown of YTHDF1 decreased Sestrin2 expression. Molecular biology prediction results showed that positions 1943 and 2,114 of Sestrin2 mRNA are high-confidence N6-methyladenosine (m6A) modification sites. Mutation of the 2,114 site on Sestrin2 mRNA inhibited the effect of YTHDF1 on 3Flag expression. Furthermore, YTHDF1 knockdown promoted IL-1\u03b2 and IL-6 production in BV2 cells, which was reversed by Sestrin2 overexpression. Microglial Sestrin2 alleviates depressive-like behaviors, cognitive impairment and neuroinflammation. YTHDF1 regulates Sestrin2 expression via an m6A-dependent mechanism, and the YTHDF1-Sestrin2 axis may represent a novel therapeutic target for major depressive disorder.",

Cannabinoid receptor 1 (CB1) plays a role in neuroprotection and modulation of inflammatory responses, making it a potential therapeutic target in MS. This study evaluated selected natural compounds as CB1 modulators using an integrated computational approach. Compounds were screened based on ADMET properties, followed by molecular docking and 100 ns molecular dynamics simulations. Berberine and curcumin demonstrated binding affinities of -7.9 kcal/mol and -9.4 kcal/mol, respectively. Key binding interactions involved residues VAL137, LEU404, PHE408, ARG405, and ARG409 for berberine, and MET363, LEU193, LEU359, TRP356, PHE189, PHE177, HIS178, PHE174, PHE379, ALA380, and SER383 for curcumin.

However, the role of environmental metal exposure remains uncertain, and the underlying mechanisms are poorly understood. A cross-sectional cohort study included 425 men from the Reproductive Health of Childbearing Couples-Anhui Cohort (RHCC-AC). Seventeen metals in seminal plasma were quantified by ICP-MS. Eight urinary oxidative stress biomarkers were measured by UPLC-MS/MS. Sperm quality parameters included sperm concentration, progressive motility, total motility, abnormality rate, and sperm DNA fragmentation index (DFI). Weighted quantile sum (WQS) regression was applied to assess single and joint effects of metal mixtures. In addition, exploratory mediation analysis was conducted to examine the potential mediating role of oxidative stress in the associations between metal exposure and sperm quality. Single-metal analyses showed that Al was positively associated with sperm abnormality rate, whereas Co and Cu were inversely associated with progressive and total motility. As, Fe, and Se were positively associated with sperm concentration. In mixture analyses, Al was the primary contributor to increased sperm abnormality rate (positive-direction WQS: \u03b2\u00a0=\u00a00.014; 95% CI: 0.004-0.024; Al weight = 0.357). Co was the main contributor to reduced total motility (\u03b2 = -0.188; 95% CI: -0.309 to -0.067; Co weight = 0.419). Few significant associations were observed between metals and oxidative stress biomarkers. Among oxidative stress markers, dityrosine(diY) was positively associated with sperm abnormality rate, while D,L-ortho-tyrosine(D,L-o-tyrosine) was negatively associated with sperm concentration. Exploratory mediation analysis revealed that D,L-o-tyrosine significantly mediated the associations of seminal plasma Hg and V with sperm concentration, with mediated proportions of 11.8% and 13.0%, respectively. Seminal plasma metal mixtures, particularly Al and Co, were associated with sperm quality. Exploratory mediation analysis suggested potential indirect effects of D,L-o-tyrosine in the associations of Hg and V with sperm concentration, but these findings should be interpreted cautiously. Further studies using seminal or reproductive tract-specific oxidative stress biomarkers are warranted to clarify the role of oxidative stress in linking metal exposure to male reproductive system injury.",

Apigenin, a dietary flavonoid, has therapeutic potential because of its neuroprotective properties. We assessed the antidepressant and anxiolytic effects of apigenin in rodent models, focusing on behavioral outcomes, mechanisms involving neuroinflammation, oxidative stress, and neurotransmitter balance, and relevant molecular pathways. A systematic search of PubMed, Scopus, and Embase was conducted through July 2025. In vivo rodent studies evaluating the effects of apigenin on depression or anxiety were included. Exclusion criteria comprised studies addressing other disorders, apigenin derivatives, or non-original research. Data on study design, model, treatment, outcomes, and mechanisms were extracted. Of 953 screened records, 21 studies met the inclusion criteria. Preclinical evidence consistently indicated that apigenin ameliorated depressive- and anxiety-like behaviors across diverse rodent models, frequently demonstrating effects comparable to or greater than those of conventional pharmacological treatments. Mechanistically, apigenin mediated its neuropsychological effects through multiple pathways, including reducing oxidative and nitrosative stress, inhibiting neuroinflammation, modulating monoaminergic neurotransmission, upregulating neurotrophic factors such as brain-derived neurotrophic factor (BDNF) and cAMP response element-binding protein (CREB), and regulating energy metabolism and neurogenesis. Apigenin exhibited a favorable safety profile across all included studies, even at high doses. In rodent models, apigenin exhibits substantial antidepressant and anxiolytic effects through complex mechanisms involving redox modulation, anti-inflammatory activity, neurotransmitter regulation, and neurotrophic support. These findings indicate that apigenin warrants further translational investigation and potential therapeutic development for treating depression and anxiety disorders.",

The major molecular driver of PTC is MAPK signaling pathway, including BRAF, RAS, and RET/PTC, but new evidence suggests the role of Wnt/\u03b2-catenin signaling pathway dysregulation in thyroid tumor development and tumor progression. The adenomatous polyposis coli (APC) gene as an important tumor suppressor gene that negatively regulates \u03b2-catenin, has attracted attention due to its role in familial adenomatous polyposis (FAP)-associated thyroid carcinoma. This review summarizes the structure and biological function of APC gene, its role in Wnt/\u03b2-catenin signaling pathway, and its contribution to the molecular pathogenesis of PTC. Furthermore, the contribution of germline and somatic APC alterations to FAP-associated thyroid tumors, and the molecular mechanisms linking APC dysregulation to thyroid carcinogenesis are discussed. In addition, we reviewed the potential diagnostic, prognostic, and therapeutic implications of APC-related molecular alterations, including their relevance to molecular testing, precision medicine, genetic counseling, and surveillance strategies. Despite the uncommon prevalence of APC mutations in sporadic PTC, some studies suggest the role of APC-related molecular abnormalities in tumor progression and the emergence of aggressive clinicopathological disease subtypes. In addition, APC mutations may have significant clinical value when integrated with other molecular markers of thyroid carcinogenesis. However, the definite clinical significance of APC mutations in PTC emergence is not fully understood, and additional prospective and translational studies are required to elucidate their biological and clinical advantages in diagnosis, prognosis, targeted therapy, and individualized patient management.",

But the interplay between ECM softening and hypoxia in regulating astrocytic activation and response remains elusive. To understand this, we developed an in vitro model incorporating tunable-stiffness hydrogels and a precise oxygen-control system to simulate the mechanical and hypoxic microenvironment of TBI. We characterized the activation-related proteins and cytokine production of astrocytes under the in vitro model, and found that soft ECM and hypoxia independently promote astrocytic activation and synergistically activate astrocytes via HIF-1\u03b1/YAP-NF-\u03baB signaling, resulting in astrocytic redox imbalance and neuroinflammation. We further used scanning electrochemical microscopy (SECM) to track the dynamic changes in glutathione (GSH) efflux and membrane integrity in live astrocytes in situ under pathophysiological conditions of ECM softening and hypoxia. The SECM results show that the combined ECM softening and hypoxia progressively impair cellular membrane integrity and promote GSH efflux of astrocytes, corresponding to the early changes in astrocytic function and indicative of an early activation-primed state to exacerbate secondary injury of astrocytes. Last, we found that the lovastatin (a neuroprotective agent) treatment can effectively attenuate astrocytic membrane impairment and decrease GSH efflux, proving the potential of lovastatin to mitigate inflammation and preserve neuroregulatory function. Our work observes the in situ and early state changes of astrocytes under a combined mechanical-hypoxic microenvironment for the first time. The findings offer mechanistic insights into TBI pathogenesis and highlight promising strategies for early therapeutic intervention.",

This review systematically examines methodological advances in brain organoid technology, from basic fabrication and brain-region-specific organoids to multicellular assembloids that incorporate microglia and vascular components, with an emphasis on strategies for overcoming fetal-like phenotypes. We surveyed literature published between 2018 and April 2026 that focused on human iPSC-derived organoid models that recapitulate core AD pathologies, including A\u03b2 plaques, tau tangles, neuroinflammation, and blood-brain barrier dysfunction. Key findings demonstrate that organoids effectively capture genotype-phenotype relationships for major AD genes (APP, PSEN1, PSEN2, and APOE\u03b54), enable the dissection of signaling pathway dysregulation (Wnt/\u03b2-catenin), and when combined with CRISPR editing and single-cell multi-omics, reveal cell-type-specific disease mechanisms. Organoids have also been successfully applied to patient-specific \"avatar\" models and high-throughput drug screening, thus advancing precision medicine approaches. However, current technological bottlenecks-including a lack of functional vascularization, batch-to-batch variability, and insufficient standardization-limit the full recapitulation of chronic, age-dependent AD pathology. This review critically evaluates these limitations, addresses ethical considerations surrounding neural organoids, and looks forward to future integration with artificial intelligence, spatial omics, and multi-organ systems to accelerate the translation of organoid-based discoveries into clinical applications.",

Given the complex, multiple pathogeneses of acute liver inflammatory injury (ALIs), this study investigates BARI in a non-sterile murine model of fulminant hepatic failure to address existing management gaps. Mice were exposed to a toxic challenge with a single dose of lipopolysaccharide (LPS, 80 \u03bcg/kg, ip) and D-galactosamine (D-GaIN, 800 mg/kg, ip) on day 3. BARI (10 and 20 mg/kg, po) were administered prophylactically from day 1 to day 3 with the last dose of BARI given 2 h before LPS/D-GaIN. Investigations revealed substantial lowering in liver function indices in BARI-treated groups after the pathogenic elevation in the LPS/D-GaIN group. These results coincided with remarkable reduction of necrosis and an improvement of hepatic architecture identified by the H&E staining in the BARI-treated groups compared to the disrupted histological features with substantial infiltration of inflammatory cells. The inflammatory cells observed in the LPS/ D-GaIN group represent a major source of ROS that contributes to nitrosative stress via the respiratory burst (NO), peroxidation of the PUFA of the cell membrane (MDA), and consumption of the cellular antioxidant molecules (TAC). This oxidative condition was reversed in BARI groups together with reestablishment of the antioxidant axis of Nrf2/HO-1 showing a remarkable capacity to restore redox equilibrium. The observed ameliorative potential of BARI is probably attributed to inhibition of IL-6 transcription, as confirmed by the inhibited activation of the transcription factor NF-\u03baB, with subsequent inhibition of JAK2/STAT3. While curbing apoptosis as evidenced by reduced levels of cleaved caspase-3, BARI presented its ability to preserve the level of PI3K/AKT/ mTOR signaling. These findings highlight the protective capacity of BARI and its value for repurpose in medical management of acute liver failure.",

There is increasing evidence linking ASD with an altered composition of the gut microbiota and chronic low-grade inflammation, suggesting a key role of the gut-brain axis (GBA) in the pathophysiological development of this condition. This mini review explores the molecular and immunological mechanisms underlying the associations between ASD and gut dysbiosis, with particular emphasis on the therapeutic potential of fecal microbiota transplantation (FMT). Dysbiosis can compromise the integrity of the intestinal barrier, increasing permeability and the translocation of pathogen-associated molecular patterns (PAMPs), such as lipopolysaccharides (LPS), thereby releasing inflammatory cytokines, including IL-6 and TNF-\u03b1. These mediators activate the mucosal immune pathways, such as the NF-\u03baB signaling and NLRP3 inflammasome, thereby contributing to neuroinflammation and elevating intestinal biomarker levels, such as S100B, RANTES, and calprotectin. Emerging evidence suggests that FMT may restore microbial diversity, promote the expansion of beneficial short-chain-fatty-acid-producing taxa, and reinforce intestinal tight junction proteins, thereby improving the integrity of the gut barrier. These effects may attenuate systemic inflammation, modulate central immune responses, regulate neurotransmitter levels, and improve gastrointestinal and behavioral outcomes in individuals with ASD. Despite these promising findings, current evidence remains limited by small sample sizes, methodological heterogeneity, and short follow-up periods. Hence, future research efforts should prioritize well-designed randomized controlled trials and the development of personalized microbial-based interventions to establish FMT as a safe and effective therapeutic strategy for ASD.",

In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain.",

However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses.",

Despite significant advances in reperfusion strategies and pharmacotherapy, persistent inflammation and adverse ventricular remodeling continue to underlie poor long-term clinical outcomes. Macrophages serve as central orchestrators of post-MI healing, coordinating the clearance of necrotic debris, resolution of inflammation, remodeling of the extracellular matrix, and maturation of the fibrotic scar. However, the conventional M1/M2 dichotomy fails to fully capture the dynamic, phenotypically heterogeneous, and metabolically constrained macrophage states that emerge during infarct healing. In this review, we synthesize current evidence supporting a trajectory-based framework for macrophage reprogramming following MI and emphasize mitochondrial fitness as a critical determinant governing the transition from sustained inflammation to reparative resolution. We summarize key metabolic checkpoints regulating this functional shift-including glycolytic rewiring, tricarboxylic acid (TCA) cycle remodeling, mitochondrial reactive oxygen species (mtROS) accumulation, efferocytosis, oxidative phosphorylation (OXPHOS), fatty acid oxidation (FAO), and mitochondrial quality control. Furthermore, we advance the hypothesis that SIRT3-the principal mitochondrial NAD+-dependent deacetylase-may act as a central regulatory node linking mitochondrial protein acetylation to macrophage state transitions after MI. Specifically, we outline a staged dual-axis working model, generated from convergent but largely indirect evidence, in which the SOD2-mtROS axis is more closely linked to early nonresolving inflammation, whereas the PDHA1-metabolic flexibility axis may be more relevant to efferocytosis-associated reparative transition. We further highlight NAD+ availability as an upstream limiting factor that may constrain SIRT3 activity in macrophages under ischemic-inflammatory stress. Finally, we critically evaluate the current evidence hierarchy, human translatability, therapeutic strategies, and key translational challenges-emphasizing considerations of timing, cellular specificity, delivery modalities, and target engagement. Although macrophage-specific causal evidence in myocardial infarction (MI) remains sparse, this framework is intended as a mechanistically coherent and experimentally tractable working hypothesis to guide future investigations into macrophage immunometabolism and mitochondrial-targeted interventions in post-infarction cardiac repair. Accordingly, the proposed framework should be viewed as a testable working hypothesis rather than a settled causal model of macrophage fate control in MI.",

Our aim is to describe the clinical spectrum, diagnostic findings, treatment, and outcomes of all pediatric CASPR2 antibody-associated encephalitis patients reported in Hungary. We present a retrospective case series including nine pediatric patients diagnosed with CASPR2 antibody-associated encephalitis across five centers. Clinical, laboratory, imaging, electrophysiological findings, treatment, and follow-up data were collected. The mean age at onset was 4.1 \u00b1 2.6 years. All patients were serum CASPR2 antibody-positive; two had CSF positivity. The most common symptoms included sleep disorder, irritability, aggressiveness, hypertension, tachycardia, abdominal pain, itching, exanthema, and weight loss. No specific abnormalities were detected on MRI, EEG, or laboratory testing. Immunotherapy led to favorable outcomes in nearly all patients, with one relapse during follow-up. This series expands the clinical spectrum of CASPR2-associated autoimmune encephalitis in children. The presenting symptoms in pediatric patients may differ not only from those observed in adults but also from other forms of autoimmune encephalitis. The diagnostic process is especially complex due to the variability and age-related evolution of clinical manifestations, which can be difficult to recognize in younger children and commonly contribute to diagnostic delay. Early recognition and immunotherapy are associated with favorable prognosis. This case series underscores the importance of recognizing the diverse spectrum of presenting symptoms and highlights the need for raising awareness of the clinical variability. Larger prospective studies are needed to define diagnostic, therapeutic strategies and prognostic factors in the pediatric population.",

However, the available evidence remains fragmented and has not been systematically integrated. This review was conducted in accordance with PRISMA guidelines. PubMed, Embase, Scopus, the Cochrane Library, and Web of Science were searched from database inception to April 3, 2026, for studies investigating glymphatic pathways, the meningeal lymphatic system, meningeal immune responses, and related imaging biomarkers in patients with clinical stroke or in experimental stroke models. Two investigators independently screened studies, extracted data, and assessed study quality. Because of substantial heterogeneity in study design, imaging methodology, experimental models, and outcome measures, findings were synthesized narratively. A total of 64 studies were included, comprising 17 clinical studies and 47 preclinical studies. Clinical studies, which were largely based on MRI-derived glymphatic imaging biomarkers, suggest that glymphatic dysfunction is associated with stroke severity, cognitive impairment, and clinical outcomes. Preclinical evidence indicates that AQP4 dysregulation, impaired meningeal lymphatic drainage, and border-associated immune activation may influence waste clearance, cerebral edema, inflammation, and tissue repair after stroke. Future studies should establish standardized imaging frameworks, conduct prospective longitudinal validation, define mechanistic differences across stroke subtypes, and facilitate the translation of targeted interventions. https://www.crd.york.ac.uk/PROSPERO/home, identifier CRD420261359988.",
        "42488724": "ID: 42488724\nTitle: BDNF-amyloid-\u03b2 Axis in Alzheimer's disease: molecular mechanisms and therapeutic perspectives.\nAbstract: Alzheimer's disease (AD), the most common cause of dementia in older adults, is characterized by progressive cognitive decline, synaptic dysfunction, and neuronal loss. Among the multifactorial mechanisms implicated in AD, reciprocal interactions between brain-derived neurotrophic factor (BDNF) and amyloid-\u03b2 (A\u03b2) have attracted increasing attention as a convergent axis linking amyloid pathology to impaired neurotrophic support. BDNF promotes neuronal resilience, synaptic plasticity, and cognitive function primarily through the activation of its high-affinity receptor, tropomyosin receptor kinase B (TrkB), and downstream signaling pathways, including PI3K-Akt and MAPK/ERK. Human postmortem and biomarker studies mainly support associations between reduced BDNF signaling, synaptic dysfunction, and AD-related pathology. In contrast, cell-based and animal studies provide mechanistic evidence that BDNF/TrkB signaling may influence amyloid precursor protein (APP) processing and neuronal resistance to A\u03b2-induced stress. Conversely, mechanistic studies indicate that A\u03b2 accumulation can suppress CREB-dependent BDNF expression, disturb BDNF transport, and impair TrkB receptor function. Thus, the BDNF-A\u03b2 relationship is better interpreted as a stage- and context-dependent pathogenic coupling rather than a simple causal loop. This review synthesizes evidence from human studies, animal models, and cellular systems to clarify how BDNF-A\u03b2 dysregulation contributes to AD progression and to discuss the translational potential of BDNF-oriented interventions.",

In a genetic Val66Met rat model, we compared the effects of a high-enrichment/high-complexity early-life environment (HE) and a low-enrichment/low-complexity environment (LE). Body weight was higher in both male and female HE rats compared to LE rats. Anxiety-like behavior on a plus maze or in an open field was enhanced in both male and female HE rats compared to LE rats. In contrast, following HE, only in females, adrenal weight was higher, and in the forced swim test, immobility was lower, and swimming was higher. Body weight and behavioral changes did not differ between BDNF genotypes. Fear conditioning and extinction were not affected. The effect of HE vs. LE condition on expression of BDNF, the antioxidant transcription factor, NRF2, and the glucocorticoid receptor, NR3C1, in the ventral hippocampus varied depending on genotype, and most of these changes were again only seen in females. There were no effects on the expression of the stress markers, SGK1 and FKBP5, or the mineralocorticoid receptor, NR3C2. These results show persistent effects of early-life environment on anxiety-like behavior and gene expression of BDNF and stress markers in adulthood, with some effects showing sex- and Val66Met genotype specificity. These results may be important for our understanding of factors involved in the development of clinical anxiety and depression, and also have implications for animal welfare in the laboratory setting.",
        "42488758": "ID: 42488758\nTitle: Substantia Nigra MRI markers are lower in Alzheimer's disease and are linked to general cognitive function.\nAbstract: Individuals with Alzheimer's disease dementia show Alzheimer's disease pathology and a heterogeneous degeneration of the Substantia Nigra (SN) post-mortem. However, it is unclear how SN degeneration is related to cognitive dysfunction across the Alzheimer's disease dementia continuum. In this study, using data from the prospective DZNE-Longitudinal Cognitive Impairment and Dementia Study (DELCODE), we investigated whether in vivo SN MRI measures are lower in individuals with clinically defined Alzheimer's disease dementia than in healthy control subjects (HC) and if they are associated with hippocampal functional activity during the processing of novel visual stimuli and subsequent recognition memory. One hundred and sixty DELCODE participants (69\u2005years \u00b1 6\u2005years, 88 men), including 79 HC, 70 individuals with subjective cognitive decline (SCD), 17 individuals with mild cognitive impairment (MCI) and 10 individuals with Alzheimer's disease dementia, completed a scene novelty and encoding task and a 3T SN-sensitive MRI scan, from which the two in vivo SN measures MRI contrast and volume were calculated and harmonized between scanner sites while preserving diagnostic group differences. For 71 individuals, CSF levels of phosphoTau, total tau and amyloid-beta 42/40 ratio (A\u00df42/40) were available. All individuals completed a neuropsychological task battery from which a global cognitive score was calculated. In separate models, we assessed the relationship between SN MRI markers and CSF levels of Alzheimer's disease, the global cognitive score, hippocampal novelty activation and recognition memory while accounting for age, sex, years of education and total intracranial volume (TIV). SN volume but not SN MRI contrast was lower in individuals with clinical Alzheimer's disease dementia [one-way analyses of covariance (ANCOVA); F(156,4) = 5.6665, P = 0.0010, n = 160]. SN MRI contrast and volume were not associated with A\u00df42/40, ptau and total tau CSF levels (all P > 0.1) or hippocampal novelty activation (all P > 0.1). Moreover, SN volume was positively associated with recognition memory (R 2 = 0.07, P < 0.001, n = 159), global cognition (R 2= 0.38, P < 0.0001, n = 160) and years of education (R 2 = 0.03, P = 0.036, n = 160). Our study emphasizes the potential of using in vivo SN MRI markers to study the impact of SN degeneration on general cognitive impairment and recognition memory in an Alzheimer's disease dementia cohort. Our results motivate future longitudinal studies to explore how SN volume and SN contrast change with disease progression, how these are differentially associated with cognitive decline, and how SN volume and SN contrast might be related to other dopamine-dependent cognitive functions and dysfunctions.",

Panax ginseng and its related preparations, including major ginsenosides (e.g., Rb1, Rg1, and Rg3), standardized extracts, and compound formulas, have garnered growing interest owing to their multi-component, multi-target pharmacological activities and integrative regulatory effects. This review systematically summarizes recent advances in the basic and clinical research of ginseng-based medicines in the prevention and treatment of cardiac fibrosis. Preclinical evidence demonstrates that ginseng and its active constituents attenuate key pathological processes, including oxidative stress, inflammatory responses, apoptosis, and autophagy dysregulation, primarily through modulation of signaling pathways such as TGF-\u03b2/Smad, NF-\u03baB, and PI3K/Akt. These regulatory effects collectively contribute to the inhibition of fibroblast activation, reduction of collagen deposition, and improvement of myocardial structure and function. Emerging clinical studies further suggested potential benefits in improving cardiac function and modulating fibrosis-related biomarkers in patients with hypertension, coronary heart disease, and heart failure (HF). Despite these promising findings, several challenges hinder clinical translation, including low oral bioavailability, the mechanistic complexity of compound formulas, and insufficient high-quality clinical evidence. Future investigations should integrate novel drug delivery strategies, systems pharmacology approaches to elucidate holistic mechanisms, and well-designed randomized controlled trials to facilitate the development of ginseng-based medicines as potential therapeutic agents for cardiac fibrosis.",

Numerous studies have shown that Huashi Baidu formula (HBF) may exert a satisfactory effect on myocardial function repair. This study aims to reveal the underlying mechanisms and main bioactive compounds (BACs) of HBF against myocardial injury. Firstly, this study established an ADR-induced mouse model to assess the protective effects of HBF against myocardial injury. Subsequently, transcriptomic profiling was conducted to screen the differentially expressed genes among the HBF treatment, ADR-induced model, and normal control groups. Following the construction and analysis of protein-protein interactions, gene set enrichment analysis, and co-expression matrix, the key targets of HBF against myocardial injury were screened and further validated based on the ADR-induced mouse model. An integrative approach combining network mapping, molecular docking, and molecular dynamics simulation was performed to identify the representative BACs. Based on an ADR-induced myocardial injury mouse model, HBF significantly ameliorated myocardial injury by improving body weight loss, decreasing mortality, and rescuing severe cardiac fibrosis. A total of 361 ADR-related genes and 42 HBF therapeutic effect-related genes were identified with the thresholds P\u00a0<\u00a00.05 and fold change (FC)\u00a0>\u00a01.2 or\u00a0<\u00a00.833. Transcriptomic profiling-based networks demonstrated that the nuclear factor erythroid 2-related factor 2 (NRF2)-cyclic AMP-dependent transcription factor ATF-3 (ATF3)-sulfiredoxin-1 (SRXN1) axis-mediated ferroptosis was the key target of HBF against myocardial injury. In vivo validation showed that HBF treatment effectively inhibited serum enzymatic biomarkers of general myocardial injury (aspartate aminotransferase, lactate dehydrogenase, and creatine kinase), myofibroblast activity (transforming growth factor beta 1 and \u03b1-smooth muscle actin), inflammatory cytokines (tumor necrosis factor-\u03b1 and interleukin-6), oxidative damage (superoxide dismutase, malondialdehyde, accumulated iron content, and TUNEL-positive cells). Mechanically, HBF may restore the dysregulation of the NRF2-ATF3-SRXN1 signal axis, leading to inhibition of ferroptosis-associated protein expression. Emodin, rhein, and lactiflorin were identified as the underlying representative BACs of HBF against myocardial injury due to the strong binding affinities between candidate BACs and key targets [Kelch-like ECH-associated protein 1 (KEAP1), ATF3, SRXN1, system Xc- (SLC3A2/SLC7A11), glutathione peroxidase 4 (GPX4), ferroportin (FPN), glutathione synthetase (GSS)]. Molecular dynamics simulations further verified these findings, revealing the stable binding among the three components and the key targets. HBF may attenuate ADR-induced myocardial injury via modulating NRF2-ATF3-SRXN1 axis-mediated ferroptosis, and emodin, rhein, and lactiflorin are potential representative BACs.",

Mounting evidence from both experimental and clinical studies has highlighted the pivotal role of T helper 17 (Th17) cells and their proinflammatory cytokines, especially interleukin-17A (IL-17A), in mediating neuroinflammation similar to that seen in experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS) models. REV-ERBs are nuclear receptors that act as transcriptional repressors and regulate immune responses, circadian rhythm, and metabolism. Synthetic REV-ERB agonists, such as SR9009, SR9011, and SR12418, have demonstrated selective suppression of Th17 differentiation and function, reduction of disease severity, and improved safety profiles in preclinical autoimmune models. In addition to Th17 differentiation, REV-ERB's role in other components of the immunomodulating system is ever-growing. Preclinical and translational data support the further exploration of REV-ERB agonists as a potential addition to the targeted immunomodulatory therapies for canine MUO. By continuing to investigate REV-ERB compounds as a component of MUO therapy, researchers can assess their potential for improved efficacy and reduce the side effects associated with traditional immunosuppressive regimens. This review integrates mechanistic insights from immunology, circadian biology, and experimental models, and outlines future directions for clinical translation, highlighting the relevance of REV-ERB agonists in advancing veterinary neuroimmunology and in informing comparative approaches to human neuroautoimmune disease.",

Yangxin Tongluo decoction (YXTLD), a traditional Chinese medicine (TCM) formula, is clinically used for such conditions, but its therapeutic effects and underlying mechanisms remain unclear. This study investigated the protective role of YXTLD against sepsis-associated cardiac dysfunction and its relationship with the Nrf2 signaling pathway. An in vivo model of sepsis was established in male C57BL/6 mice via intraperitoneal lipopolysaccharide (LPS) injection. Cardiac function was assessed by echocardiography and serum biomarkers (creatine kinase [CK], lactate dehydrogenase [LDH]). In vitro, LPS-stimulated H9c2 cardiomyocytes were treated with various doses of YXTLD. Cell viability, inflammation (interleukin [IL]-1\u03b2, IL-6, TNF-\u03b1), oxidative stress (reactive oxygen species [ROS], malondialdehyde [MDA], catalase [CAT], glutathione [GSH]), and apoptosis were evaluated. The involvement of the Nrf2 pathway was examined using western blotting. In vivo dosage: YXTLD was administered intraperitoneally five times prior to LPS induction and continued after induction (total of seven doses over 48\u2009h). In vitro concentrations: low (50 \u03bcg/mL), medium (100 \u03bcg/mL), and high (150 \u03bcg/mL) YXTLD. YXTLD significantly improved cardiac function and alleviated myocardial injury in septic mice, as evidenced by increased ejection fraction (EF; 97.87%\u2009\u00b1\u20091.20% vs. 79.05%\u2009\u00b1\u20093.04%) and fractional shortening (FS; 74.99%\u2009\u00b1\u20095.58% vs. 41.98%\u2009\u00b1\u20092.72%), together with reduced serum CK (188.60\u2009\u00b1\u200981.16 vs. 566.75\u2009\u00b1\u2009186.24\u2009U/L) and LDH (179.70\u2009\u00b1\u200954.47 vs. 463.65\u2009\u00b1\u2009197.58\u2009U/L) levels compared with the LPS group (all p\u2009 < 0.05). In LPS-stimulated H9c2 cells, YXTLD dose-dependently enhanced cell viability, suppressed the expression of pro-inflammatory cytokines (IL-6, IL-1\u03b2, and TNF-\u03b1), reduced ROS production and lipid peroxidation, restored antioxidant capacity, and inhibited apoptosis. At 50\u2009\u03bcg/mL, YXTLD markedly decreased IL-6, IL-1\u03b2, and TNF-\u03b1 levels by ~78%, 63%, and 92%, respectively (all p < 0.05). ROS and apoptotic cell proportions were progressively reduced with increasing YXTLD concentrations, reaching reductions of ~82% and 95%, respectively, at 150\u2009\u03bcg/mL (p < 0.001). Mechanistically, YXTLD activated the Nrf2 signaling pathway by promoting nuclear Nrf2 translocation and upregulating its downstream antioxidant proteins, including heme oxygenase-1 (HO-1), NAD(P)H quinone dehydrogenase 1 (NQO1), and glutamate-cysteine ligase modifier (GCLM). YXTLD also restored CAT and GSH levels while reducing MDA accumulation, indicating attenuation of oxidative stress. YXTLD protects against sepsis-induced cardiac dysfunction by attenuating inflammation, oxidative stress, and apoptosis through activation of the Nrf2 signaling pathway. These findings provide a pharmacological basis for YXTLD as a potential therapeutic strategy for sepsis-associated cardiac dysfunction.",

Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement. Reprogramming central-peripheral immune crosstalk with PBM resolves neuroinflammation and restores cognition in AD models-a translatable strategy for combating neurodegeneration.",

AD patients frequently experience recurrent systemic inflammatory insults from comorbid conditions, which act as\u00a0\"secondary-hits\" believed to worsen cognitive decline. The impact of these secondary insults \u00a0on astrocyte-mediated neurovascular regulation remains unknown. We applied intravital two-photon microscopy to longitudinally investigate astrocytic Ca2 + dynamics and functional hyperemia during sensory stimulation in APP/PS1dE9 mice before and during secondary lipopolysaccharide (LPS)-induced systemic inflammation. AD mice exhibited diminished stimulation-evoked astrocytic Ca2 + activity, while functional hyperemia remained largely preserved. LPS further suppressed astrocytic Ca2 + responses and produced temporally specific vascular alterations, with AD and wild-type mice following divergent inflammatory trajectories. Our findings provide the first in vivo longitudinal characterization of how secondary systemic inflammation disrupts astrocyte-mediated neurovascular regulation. The selective vulnerability of astrocytic Ca2 + signaling relative to vascular output implicates recurrent inflammatory insults as a clinically relevant contributor to neurovascular dysfunction in preclinical AD.",

The human dental pulp stem cell (hDPSC) secretome is a promising cell-free therapeutic candidate containing neurotrophic, antioxidant, and immunomodulatory factors. Here, we investigated its therapeutic effects in a photothrombotic mouse model of ischemic stroke and CoCl2-induced hypoxic BV2 microglial cells. Proteomic profiling identified antioxidant-associated proteins, including SOD2, GSR, and GSTP1, and microglial phenotype-related candidates, including GRN, CSF1, and LRP1. hDPSC secretome treatment reduced stroke-induced infarct volume and attenuated stroke-increased neuronal apoptosis, neuronal ROS accumulation, and NF-\u03baB-associated inflammatory signaling in the cortex and hippocampus. It also shifted microglial marker expression toward an M2-associated profile and improved stroke-impaired hippocampal neurogenesis, vascular remodeling, and synaptic organization. Proteomic analyses further identified coordinated changes in pathways related to oxidative phosphorylation, inflammatory responses, calcium signaling, SNARE-associated vesicular transport, and ROBO-Rho-associated cytoskeletal remodeling. These molecular and cellular changes were associated with improved motor coordination, spatial learning and memory, contextual memory, and anxiety-like behavior. These findings support the hDPSC secretome as a cell-free therapeutic candidate for post-stroke functional recovery linked to redox, inflammatory, neurovascular, and synaptic remodeling.",

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.",

Here, we report a strategy to rewire the pyroptotic pathway by bypassing Casp-3 to directly activate gasdermin D (GSDMD). We identify a small-molecule agonist, (E)-2,3-diiodobut-2-ene-1,4-diol (DIBDO), which undergoes deiodination to release iodide ions upon activation by the tumor-abundant nucleophile glutathione, thereby catalytically generating singlet oxygen and molecular iodine. This cascade induces oxidative damage that downregulates key mediators of caspase-9 and caspase-8 pathways, thereby down-regulating Casp-3 activation. This mechanism selectively triggers GSDMD-mediated pyroptosis, provoking robust immunogenic cell death and inflammatory cytokine release to reconfigure the tumor immune microenvironment. In murine tumor models, DIBDO enhances tumor infiltration of cytotoxic T cells and synergizes with checkpoint blockade therapy to suppress both primary and distal tumors. It can also serve as an in situ or exogenous vaccine to elicit potent and durable antitumor immunity. This work presents a paradigm-shifting approach to cancer immunotherapy by decoupling pyroptosis from Casp-3 dependence, offering a promising avenue to expand the scope of immunogenic cell death-based treatments.",

However, the specific impact of Hsa21 genes on these risks is not yet fully understood.ObjectiveTo investigate how triplication of mouse chromosome 16 (Mmu16), homologous to Hsa21, affects amyloid-\u03b2 (A\u03b2) accumulation in the brain and epileptic seizures in AD-DS model mice.MethodsTo generate AD-DS model mice, we crossed a mouse model of aspects of AD-an APPswe/PS1dE9 mouse exhibiting brain A\u03b2 accumulation and sudden death associated with epileptic seizures with DS mouse models carrying an extra copy of partial segments of mouse chromosome 16. We used three DS model lines: Ts1Cje, harboring a triplicated region encoding \u223c70 Hsa21-homologous genes (Scaf4-Zbtb21); Ts1Rhr with triplication of the Cbr3-Fam3b region; and a newly developed Ts1Kei mouse carrying an extra copy of the Scaf4-Cbr1 region. A\u03b2 accumulation was assessed by immunohistochemistry and enzyme-linked immunosorbent assay.ResultsCompared with APPswe/PS1dE9 mice, A\u03b2 deposition and insoluble A\u03b2 levels in the brain decreased in APPswe/PS1dE9-Ts1Cje mice but not in APPswe/PS1dE9-Ts1Rhr mice. The high mortality in APPswe/PS1dE9 mice was suppressed by either Ts1Cje- or Ts1Rhr-triplicated region. Despite a tendency for decreased A\u03b2 accumulation in APPswe/PS1dE9-Ts1Kei mice, the study could not be finished due to the extremely high mortality.ConclusionsThe trisomic region in Ts1Kei mice is suggested to harbor genes associated with decreased A\u03b2 accumulation. Alternatively, the trisomic region in Ts1Rhr mice contains genes suppressing sudden death in APPswe/PS1dE9 mice.",

Participants were classified into irritability-positive (+) and irritability-negative (-) groups based on assessment of irritability.We used Linear mixed-effects models to assess irritability-related cognitive trajectory, Cox regression to estimate cognitive decline, mediation analysis to test the effect of amyloid-\u03b2 (A\u03b2) on the relationship between irritability and cognitive decline, and enrichment analysis to identify the underlying pathological mechanisms of irritability.ResultsIrritability was associated with increased cognitive decline in both ADNI (HR\u2009=\u20091.49, 95% CI: 1.12-1.98) and UKB (HR\u2009=\u20091.09, 95% CI: 1.04-1.15) cohorts, with baseline irritability linked to faster Mini-Mental State Examination decline (2.76 versus 1.88). Mediation analysis showed that cerebrospinal fluid (CSF) A\u03b2 mediated 19-24% of irritability's effect on cognitive decline, while precuneus A\u03b2 pathology mediated 30-41%. Imaging analysis revealed significant thinning of the left precuneus cortex in individuals with irritability. Proteomic analysis indicated underlying pathways involving enhanced energy metabolism and suppressed signal transduction, with modifiable factors (air pollution and physical inactivity) associated with irritability-related pathological proteins.ConclusionsOur findings indicate that irritability is significantly associated with cognitive decline. This association may be driven by mechanisms involving precuneus pathology, increased energy metabolism, and suppressed signal transduction, though these results warrant confirmation in future studies.",

Extracellular A\u03b2 deposition in the isocortex is observed before substantial NFD develops, but in the allocortex (temporal lobe) there are no A\u03b2 deposits in 50% of subjects despite extensive NFD. Cytoskeletal lesions in the allocortex consist of atrophic grid cells, abundant pretangles, neuropil threads, neurofibrillary tangles, and neuritic plaques; isocortical sites show either no NFD at all or only minimal NFD presenting as solitary pretangles or tangles, neuropil threads, or droplet degeneration spheres from ferroptotic neurons. Presence of degenerating grid neurons in entorhinal cortex coincides with microglial apoptosis.ConclusionsNeuroprotection via ferritin expression and A\u03b2 deposition is more effective in the isocortex than in allocortex. Findings support the hypothesis that degeneration or death of neuroprotective microglia promotes neuronal degeneration.",

This review provides an integrative overview of the molecular and biochemical modulators governing synaptic plasticity and their disruption in AD. We discuss how the collective impairment of A\u03b2 aggregation, tau pathology, calcium imbalance, oxidative stress, and neuroinflammation affects dendritic spine morphology and synaptic connectivity. Particular attention is given to neurotrophins such as brain-derived neurotrophic factor and TrkB signaling, hormonal influences, likewise glucocorticoids, estrogens, testosterone, endocannabinoid pathways, lipid and cholesterol regulators like ApoE and lipid rafts, and epigenetic mechanisms that modulate synaptic resilience. We further evaluate the therapeutic potential of pharmacological agents, including cholinesterase inhibitors, NMDA receptor modulators, and multi-target directed ligands alongside nutraceuticals such as resveratrol, curcumin, omega-3 fatty acids, Withania somnifera, and Bacopa monnieri. Emerging technologies, including iPSC-derived neuronal models, optogenetics, and advanced neuroimaging biomarkers like SV2A PET, cerebrospinal fluid/plasma neurogranin, are also highlighted for their role in elucidating and monitoring synaptic integrity. Ultimately, targeting the biochemical modulators of synaptic plasticity offers a promising avenue for AD therapy, especially through combinatorial and precision-medicine strategies aimed at restoring synaptic function and cognitive performance.",

However, its mechanism of action is not completely understood. One proposed mechanism involves the modulation of central and peripheral inflammatory circuits. This exploratory study enrolled 28 participants (11 healthy controls [HC] and 17 patients with chronic back and/or leg pain of various origin). Pain intensity (Numeric Rating Scale), sleep quality (Pittsburgh Sleep Quality Index), mood (Beck Depression Inventory), disability (Oswestry Disability Index), and levels of pro- and anti-inflammatory cytokines (adiponectin, ghrelin, interleukin [IL]-10, high-mobility group box 1-protein, tumor necrosis factor alpha, IL-6, IL-1\u03b2, leptin) were collected at baseline and after three months of burst SCS and compared with HC. A total of 11 men and six women (mean age 68.4 \u00b1 11.2 years) underwent permanent SCS implantation. Pain intensity significantly decreased at follow-up (p < 0.001), accompanied by improvements in sleep quality (p = 0.002), mood (p = 0.001), and disability (p < 0.001). At baseline, proinflammatory tumor necrosis factor alpha levels were significantly elevated (p = 0.006), whereas anti-inflammatory IL-10 levels were significantly reduced compared with HC (p = 0.004). At follow-up, IL-10 levels increased, attenuating the difference between patients and HC such that no statistical significance was observed. Levels of pro- and anti-inflammatory cytokines showed no significant correlations with clinical outcome measures. Consistent with previously published data, we found a proinflammatory profile in patients with chronic pain at baseline. After three months of burst SCS anti-inflammatory IL-10 was increased along with improved pain and functional capacity. However, a causal relationship between burst SCS and neuroinflammatory mediators in chronic back and/or leg pain could not be established.",

This study investigates the neurotoxicity of NM-300K AgNPs, which are Representative Manufactured Nanomaterials (RMNs), through in vitro assays using NG108-15 neuronal cells and in vivo experiments with BALB/c and Kunming mice. In vitro results showed an IC50 value of 100 \u00b5g mL-1 for NG108-15 cells, with a sub-lethal concentration of 25 \u00b5g mL-1 selected for further analysis. Proteomic analysis identified 96 significantly upregulated proteins, indicating activation of stress response pathways. Behavioral assessments revealed that mice exposed to 0.5 mg kg-1 day-1 AgNPs exhibited cognitive deficits, while those receiving 10 mg kg-1 day-1 displayed hyperactivity and increased anxiety-like behaviors. Histopathological examinations indicated neuronal vacuolation and loss in the CA3 region of the hippocampus, correlating with behavioral impairments. Biomarker analysis demonstrated significant oxidative stress, as evidenced by elevated reactive oxygen species (ROS) levels, increased interleukin-6, and increased Nrf2 levels. Exposure to high doses of AgNPs also led to reduced total antioxidant capacity (T-AOC), decreased glutathione (GSH), and elevated tumor necrosis factor-alpha (TNF-\u03b1), indicating an inflammatory response and activation of apoptotic pathways (caspase-3), suggesting that exposure to AgNPs can lead to neuronal dysfunction and cell death. These findings contribute to understanding the neurotoxic mechanisms of AgNPs, highlighting the need for thorough risk assessments and regulatory measures to mitigate potential health impacts associated with nanoparticle exposure.",

Mercuric chloride (HgCl2) is a toxic inorganic heavy metal compound that induces significant hematotoxic, hepatotoxic, neurotoxic, nephrotoxic, and genotoxic effects in biological systems. Therapeutic strategies targeting HgCl2-induced liver damage remain inadequately investigated. This study evaluated Man's protective effect against HgCl2-induced acute liver injury and the possible molecular mechanisms of hepatic protection effects in mice. Adult male BALB/c mice were administered two doses of Man (50 and 100 mg/kg, PO) 2 h before daily injections of HgCl2 (3 mg/kg, IP) for seven consecutive days. The results indicated Man's protective capabilities, as shown by marked improvement in hepatic histological abnormalities caused by HgCl2, along with the normalization of blood liver enzyme levels (ALT, AST, and LDH). These protective effects can be attributed to (i) cellular oxidative balance restoration via Nrf2 activation, TAC recovery, and NO and MDA reduction; (ii) suppression of pro-inflammatory signaling (NF-\u03baB, NLRP3, IL-1\u03b2, and Casp-1); (iii) apoptotic-proliferative homeostasis restoration via Bax downregulation and Bcl-2 upregulation; and (iv) endoplasmic reticulum stress attenuation (PERK and CHOP). In conclusion, Man could be considered as a potential protective agent against HgCl2-induced liver injury through controlling oxidative stress, inflammation, and apoptosis.",

Alterations in membrane fatty acid composition, particularly the imbalance between pro-inflammatory arachidonic acid (AA) and anti-inflammatory eicosapentaenoic acid (EPA), contribute significantly to disease progression. Despite the anti-inflammatory properties of EPA are well established, its clinical application is limited by poor bioavailability. Therefore, this study investigated the therapeutic efficacy and molecular mechanisms of an EPA-loaded silica nanoemulsion (EPA-NE) in a diethylnitrosamine (DEN)-induced rat model of hepatic fibroinflammation. Thirty-two male Wistar albino rats were randomly allocated into four groups: control, DEN-induced hepatic fibroinflammation, DEN\u2009+\u2009EPA, and DEN\u2009+\u2009EPA-NE. Biochemical, molecular, histopathological, and bioinformatic analyses were performed to evaluate treatment outcomes. Both EPA and EPA-NE significantly restored membrane EPA/AA homeostasis, increasing the EPA/AA ratio, and attenuated hepatic injury. EPA and EPA-NE reduced serum homocysteine levels by 57.4% and 72.3%, respectively, and suppressed NF-\u03baB levels by 27.5% and 54.5%, respectively, compared with the DEN group (P\u2009<\u20090.0001). Moreover, EPA and EPA-NE enhanced antioxidant defenses, as evidenced by increased hepatic catalase activity by 1.7-fold and twofold, respectively, while reducing malondialdehyde levels by 23.1% and 46.2% (P\u2009<\u20090.0001), respectively. Molecular analyses demonstrated significant downregulation of PKC\u03b1 expression and upregulation of Nrf2 and miR-34a expression, indicating attenuation of inflammatory and oxidative stress pathways. Histopathological examination further confirmed the marked reduction of hepatic fibroinflammatory alterations following treatment, with EPA-NE exhibiting superior efficacy compared with EPA. In conclusion, EPA-loaded silica nanoemulsion effectively attenuated DEN-induced hepatic fibroinflammation, restored fatty acid homeostasis, reduced homocysteine levels, and modulated molecular markers associated with oxidative stress and inflammation. These findings suggest that nanoemulsion-based delivery enhances the biological activity of EPA and support the potential of EPA-NE as a promising therapeutic strategy for hepatic fibroinflammation.",

We tested whether pentoxifylline (PTX), a methylxanthine phosphodiesterase inhibitor with dual hemorheological and anti-inflammatory properties, attenuates VCI-like cognitive and inflammatory abnormalities in a rat model. Three-month-old male Sprague-Dawley rats underwent bilateral common carotid artery occlusion (BCCAO) or sham surgery. PTX (60\u00a0mg\u00a0kg\u207b1\u00a0day\u207b1, gavage) or vehicle was administered for 28\u00a0days starting 24\u00a0h post-operation. Spatial cognition was assessed with the Morris water maze; neuronal injury, microglial activation, and glucose metabolism were evaluated by histology, immunofluorescence, 1\u2078F-FDG PET/CT, and western blotting. Systemic and hippocampal cytokines were quantified by multiplex immunoassay; TLR4/MyD88/NF-\u03baB signaling was profiled by RNA-seq and western blotting. BCCAO induced progressive cognitive deficits without sustained weight loss, paralleled by CA1 neuronal damage, microglial proliferation, and marked elevations of IL-1\u03b2, IL-2, IL-17, and TNF-\u03b1 in plasma and hippocampus. PTX shortened escape latency, restored probe-trial platform crossings, preserved neuronal morphology, suppressed microglial Iba-1\u207a/Ki67\u207a expansion, and reduced all four cytokines. Mechanistically, PTX down-regulated TLR4, MyD88, and NF-\u03baB p65 mRNA and protein, reduced nuclear translocation of NF-\u03baB p65, and partially reversed frontal and hippocampal glucose hypometabolism. Peripheral IL-1\u03b2 and IL-17 levels correlated positively with cognitive impairment. Pentoxifylline concurrently mitigates hypoperfusion-associated neuroinflammation, neuronal injury, and glucose hypometabolism via inhibition of the TLR4/MyD88/NF-\u03baB axis, supporting PTX as a readily translatable candidate for early VCI intervention.",

Despite its multifactorial nature, only a few pharmacological therapies have been approved by the Food and Drug Administration (FDA), and these mainly provide symptomatic relief. Many patients experience inadequate efficacy or intolerable adverse effects, emphasizing the need for further research and improved therapeutic strategies. This review highlights contributing factors in the pathophysiology of FM, including neurochemical alterations, central sensitization, neuroinflammation, oxidative stress, mitochondrial dysfunction, gut microbiota disturbances, and autoimmunity. While some of these factors are well-established, others remain under investigation. Therapeutic strategies are discussed alongside repurposed drugs in preclinical and clinical studies, including N-methyl-D-aspartate (NMDA) receptor antagonists, neurokinin-1 receptor antagonists, drugs targeting the gamma-aminobutyric acid (GABA) system, antiepileptics, antidepressants, opioids, cannabinoids, dopamine receptor agonists, melatonin receptor agonists, and antidiabetics. Future research frontiers in FM should focus on addressing comorbidities and targeting central sensitization by enhancing descending inhibitory pain pathways, suppressing neuroinflammation through NOD-like receptor protein 3 (NLRP3) inflammasome inhibition and promotion of anti-inflammatory glial polarization besides attenuating oxidative stress and mitochondrial dysfunction. Moreover, repurposing drugs from related pain conditions such as migraine and neuropathic pain offers new therapeutic opportunities. Accordingly, this multi-target strategy may facilitate the development of effective therapies for FM.",

In this study, we evaluated the hepatotoxic effects of polystyrene nanoplastics (PsNPs) and gentamicin (GEN), administered alone or in combination, and investigated the underlying molecular mechanisms using both in vivo and in silico approaches. Our findings demonstrated that co-exposure to PsNPs and GEN induces combined treatment response in liver by triggering oxidative stress, inflammation and apoptosis responses, associated with a dysregulation of genes related to oxidative stress (NRF2), inflammation (TNF-\u03b1, IL-1\u03b2), and apoptosis (Bax, Bcl-2, caspase-9, and caspase-3). Molecular docking analyses further supported these observations by revealing strong binding affinities of nanoplastics with key proteins involved in oxidative stress and inflammatory pathways. Our results revealed that co-exposure of adult rats to PsNPs and GEN induces an adverse effect on hepatic function. This study provides new evidence on the combined toxicity of polystyrene nanoplastics and pharmaceutical pollutants on liver function, suggesting a potential co-exposure-associated effect interaction between these contaminants.",

Human mesenchymal stem cells (hMSCs) offer multimodal neuroprotection through paracrine secretion of neurotrophic factors and immunomodulatory mediators. We reviewed preclinical and clinical evidence for hMSC therapy across multiple CA etiologies, integrating findings from neuroinflammatory, toxic/developmental, and genetic mouse models alongside published clinical trials and case reports. A systematic literature search was conducted in PubMed/MEDLINE, Embase, and the Cochrane Library (search period: 2000-2026) using the following key terms: \"mesenchymal stem cell\" AND \"cerebellar ataxia\"; \"MSC\" AND \"spinocerebellar ataxia\"; \"hMSC\" AND \"Purkinje cell\"; \"stem cell therapy\" AND \"ataxia\". Inclusion criteria encompassed: peer-reviewed original research articles and reviews in English; in\u00a0vivo animal model studies; clinical trials, case series, and case reports. Studies addressing non-CA neurological conditions without CA-relevant data were excluded. hMSC transplantation consistently improved motor function, preserved Purkinje cell integrity, and attenuated neuroinflammation across LPS-induced, Ara-C-induced, and SCA2 transgenic models. A critical observation is that MSCs from CA patients exhibit markedly reduced anti-inflammatory secretome capacity compared with healthy-donor MSCs, justifying an allogeneic strategy. Therapeutic efficacy was maintained even after symptom onset in the SCA2 model. A published case report demonstrated safety and preliminary functional benefit of intrathecal allogeneic bone marrow-derived MSCs in a sporadic adult-onset ataxia patient. hMSC therapy targets convergent CA pathomechanisms-microglial suppression, neurotrophin restoration, and Purkinje cell preservation-through a paracrine rather than cell-replacement mechanism. Post-symptomatic efficacy and an emerging clinical evidence base support advancing toward placebo-controlled randomized trials.",

Unlike prior reviews focused predominantly on aggregation as an isolated endpoint, this review proposes a neurodevelopmental-neurodegenerative continuum as an interpretive framework, suggesting that \u03b1-Syn's physiological roles in synaptic development and circuit maturation may be linked to its later pathological behaviour. Within this context, we discuss recent advances in small-molecule strategies targeting key stages of \u03b1-Syn pathology, including synthesis, misfolding, aggregation, post-translational modification, and clearance. These include translation and misfolding inhibitors, aggregation modulators such as minzasolmin (UCB0599), epigallocatechin gallate and anle138b, as well as compounds that enhance \u03b1-Syn degradation through autophagy-lysosomal and ubiquitin-proteasome pathways. Additional strategies targeting proteostasis and mitochondrial dysfunction are also considered. Beyond its pathogenic role, \u03b1-Syn contributes to synaptic vesicle trafficking, neurotransmitter release, and neuronal maturation, and disruption of these functions may increase vulnerability to later neurodegeneration. In conclusion, small-molecule-based therapies represent a promising multi-targeted strategy for PD; however, key translational challenges and unresolved questions remain, including optimisation of pharmacokinetics, target specificity, and blood-brain barrier (BBB) penetration and validation in clinical settings.",

This study evaluated the effect of gamete co-incubation duration (2-h intervals from 2 to 24\u00a0h) on embryo development and blastocyst competence. A total of 3680 cumulus-oocyte complexes (COCs) were recovered from 1163 buffalo ovaries. Grade A and B COCs (n\u2009=\u20092390) were matured in vitro, and 2324 matured oocytes were subjected to IVF using different gamete co-incubation durations, followed by culture of 2012 presumptive embryos for 7 days. Cleavage, blastocyst development, and developmental competence were assessed using RT-qPCR. Cleavage rate was significantly affected (P\u2009<\u20090.05), increasing from 65.2% at 2\u00a0h to 100% at 8\u00a0h and remaining comparable between 10 and 24\u00a0h (81.7-97.1%). Blastocyst development increased progressively, reaching the highest rates at 16-20\u00a0h (53.2-54.9%; P\u2009>\u20090.05), before declining significantly at 22\u00a0h (32.7%) and 24\u00a0h (28.0%). Embryonic arrest was significantly lower in the 16-20\u00a0h groups. Blastocysts produced after 16-20\u00a0h exhibited higher (P\u2009<\u20090.05) expression of HSPB1, SOD2, GPX3, GDF9, BMP15, STAR, and BCL2, with lower BAX and CASP3 expression, indicating enhanced developmental competence. Although blastocysts developed following as little as 2\u00a0h of gamete co-incubation, a duration of 16\u00a0h produced outcomes comparable to the conventional 20-h protocol. Therefore, 16-20\u00a0h represents the optimal gamete co-incubation window for maximizing blastocyst yield and developmental competence in buffalo IVF.",

This study explored the protective role of exogenous trehalose (25, 50, and 75\u2009mM) in mitigating arsenic-induced physiological and biochemical disturbances in Brassica juncea at 30, 60, and 90\u2009d after sowing. As stress significantly reduced photosynthetic pigments, including chlorophyll a (up to 72.91%), chlorophyll b (77.71%), total chlorophyll (56.49%), carotenoids (33%-43%), xanthophylls (42%-43%), and anthocyanins (38.82%). Concurrently, oxidative stress markers increased markedly, with malondialdehyde rising by 22%-46% and hydrogen peroxide (H\u2082O\u2082) by 12%-59%, indicating severe ROS-induced cellular damage. Foliar application of trehalose effectively alleviated these negative effects in a dose-dependent manner. Trehalose (75\u2009mM) showed the highest efficacy, enhancing chlorophyll a by 49%-88%, chlorophyll b by 56%-78%, total chlorophyll by 52%-66%, carotenoids by 42%-48%, and xanthophylls by 44%-58% compared to As-stressed plants. It also substantially improved the anthocyanin content and decreased MDA levels by 25%-29%, reflecting reduced lipid peroxidation and improved antioxidant defense. While H\u2082O\u2082 levels displayed some variability, trehalose consistently moderated its accumulation under As stress. Overall, trehalose significantly restored the pigment profiles, reduced oxidative damage, and enhanced stress tolerance, with 75\u2009mM emerging as the most effective concentration. These results highlight trehalose as a promising and eco-friendly strategy to improve plant resilience and productivity under arsenic-contaminated conditions.",
        "42490144": "ID: 42490144\nTitle: Progressive hypothalamic neuroinflammation in ovariectomized mice parallels aging-related transcriptomic changes in the female human hypothalamus.\nAbstract: The hypothalamic changes that occur after the loss of ovarian estrogen remain poorly characterized. Here, we performed a comprehensive temporal characterization of the mouse hypothalamus following ovariectomy (OVX), combining physiological measurements with bulk RNA-sequencing of the posterior hypothalamus (PH) and preoptic area (POA) at short-term (14 days) and long-term (4 months) post-OVX. Serum LH levels rose progressively and then declined, while core temperature peaked early and subsequently normalized, recapitulating the endocrine and thermoregulatory dynamics of reproductive aging in humans. Transcriptomic analysis revealed time-dependent activation of inflammatory pathways, glial markers, and KNDy neuron-related gene networks, with the most pronounced changes emerging at 4 months post-OVX, particularly in the PH. Immunofluorescence confirmed increased NKB release, declining KNDy neuronal activity, and heightened astrocytic reactivity in the arcuate nucleus after prolonged estrogen withdrawal. To contextualize these findings, we analyzed publicly available human hypothalamic RNA-seq data across chronological age. Age-related transcriptomic patterns in women, including progressive inflammatory signaling, glial activation, and altered KNDy gene expression, showed significant correlation with the OVX mouse model, particularly at the pathway level. These findings establish a temporal framework for hypothalamic molecular changes after estrogen withdrawal, identify conserved neuroinflammatory signatures across species, and provide a preclinical platform for testing interventions targeting menopausal-associated hypothalamic dysfunction.",

This study sought to identify and evaluate diagnostic plasma protein biomarkers for SLE. We analyzed plasma protein profiles, polygenic risk scores (PRS), and clinical data from 544 SLE cases and 48,036 controls in the UK Biobank. Using LASSO regression, we identified 35 high-confidence SLE-associated proteins and derived a protein risk score (ProtRS). The ProtRS model achieved exceptional diagnostic performance (AUC\u2009=\u20090.91), significantly outperforming models based on PRS or clinical factors alone. Notably, a cost-optimized 5-protein panel (TRIM21, SOD2, KLK3, IL15, ADIPOQ) retained high accuracy (AUC\u2009=\u20090.82) while reducing costs by ~87%. ProtRS also demonstrated the highest population attributable fraction (96.34%), underscoring its dominant contribution to SLE burden. This study establishes a protein-driven framework for early SLE detection, offering tiered diagnostic solutions to balance accuracy and cost. The findings underscore the translational potential of protein biomarkers in bridging theoretical research and clinical practice.",

Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke.",

This review gathers current evidence that connects disruptions in microbial metabolites to the pathogenesis of neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). Our comprehensive overview discusses major neuroactive metabolite classes-short-chain fatty acids (SCFAs), tryptophan derivatives, bile acids, and phenolic compounds-and their established roles functions in affecting neuroinflammation, epigenetic programming, synaptic function, and blood-brain barrier integrity. Converging evidence from human multi-omics studies and preclinical models frequently reported patterns of metabolic dysregulation in NDDs, including reduced SCFA production, altered kynurenine pathway metabolites, and accumulation of neurotoxic compounds such as para-cresol (p-cresol). However, substantial heterogeneity exists across studies, and causal evidence in humans remains predominantly associative. We further examine the critical early-life window during which the metabolite-producing microbiome is shaped by maternal factors, nutrition, and environmental exposures, with lasting consequences for neurodevelopmental trajectories. Finally, we discuss new intervention strategies such as probiotics, dietary substrates, fecal microbiota transplantation, and metabolite-based therapies, and propose a plan to transition from associative findings to causal, personalized approaches using microbial metabolites as biomarkers and therapeutic targets in child neurodevelopment.",
        "42490925": "ID: 42490925\nTitle: Sensory signaling mediates the systemic metabolic and neurological effects of epigallocatechin gallate.\nAbstract: Epigallocatechin gallate (EGCG), the primary green tea flavanol, is renowned for its diverse health benefits; however, its low systemic bioavailability presents a long-standing paradox in nutritional science. We hypothesized that EGCG exerts its physiological effects via oral chemosensory signaling pathways, independent of intestinal absorption. This study utilized wild-type and Skn-1a-/- mice (lacking bitter taste signaling) to evaluate acute metabolic responses. Furthermore, a chronic study using high-fat/high-sucrose diet (HFSD)-fed rats was conducted to investigate the long-term effects of EGCG on systemic metabolism, neuroinflammation, and adipose and skeletal muscle morphology. Acute oral administration of EGCG or the bitter tastant denatonium benzoate significantly attenuated glycemic excursions and elevated plasma glucagon-like peptide-1 (GLP-1) levels in wild-type mice. Crucially, these effects were completely abolished in Skn-1a-/- mice, identifying bitter taste receptors as essential mediators. In the chronic rat model, repeated oral EGCG treatment effectively reduced food intake, body weight gain, and adiposity. Beyond metabolic regulation, EGCG suppressed Iba-1 expression in the hippocampal dentate gyrus, indicating an anti-neuroinflammatory effect. Notably, EGCG increased the cross-sectional area of both the soleus and extensor digitorum longus muscles across all diet groups, mimicking the beneficial effects of physical exercise. These findings indicate that EGCG acts as a \"metabolic trigger\" through Skn-1a-dependent chemosensory pathways, primarily involving T2R signaling. By demonstrating that bitter-related chemosensory signaling regulates systemic homeostasis and provides neuroprotective effects, this study supports a new concept of \"sensory nutrition.\" This research positions gastrointestinal and oral chemosensors as a novel and non-invasive therapeutic target for managing metabolic syndrome and cognitive decline, overcoming the limitations of systemic bioavailability.",

Large language models (LLMs) may improve scalable pharmacovigilance. We analyzed 20,123 clinical documents from 46 patients who received at least one dose of anti-A\u03b2 therapy (June 24, 2024-July 30, 2025) at a large mid-Atlantic health-care system. We compared standard expert review versus an LLM-augmented workflow applied to the same documents. Expert reviewers annotated therapy-related AEs (e.g., amyloid-related imaging abnormalities with edema or hemorrhage, headache, syncope, hypersensitivity, gastrointestinal symptoms, infusion reactions). Discordant cases were adjudicated to establish a reference label. After adjudication, 76% (35/46) patients had an AE. The LLM-augmented workflow achieved 100% sensitivity (positive predictive value [PPV] 89.7%) versus expert review 88.6% sensitivity (PPV 100%). Findings provide preliminary indications that LLMs may serve as a pharmacovigilance signal detection tool, with a need for further validation and evaluation of clinical integration.",
        "42491038": "ID: 42491038\nTitle: Progress in traditional Chinese medicine for chemotherapy-induced nausea and vomiting, based on the theory of \"Fuzheng Quxie\" and \"Hewei Jiangni\".\nAbstract: Chemotherapy-induced nausea and vomiting (CINV) is among the most prevalent adverse reactions in cancer treatment. It significantly diminishes the quality of life of patients and their treatment compliance. Traditional Chinese medicine (TCM) exhibits unique characteristics and potential for the prevention and treatment of CINV. This review summarizes the latest research progress on TCM for CINV, encompassing the theoretical foundation, mechanism of action, and clinical evidence. \"Fuzheng Quxie\" formulas (reinforcing healthy Qi and eliminating pathogenic factors) and herbs (e.g., Liu-Jun-Zi-Tang, ginseng) enhance the body's tolerance to chemotherapy by enhancing immunity, reducing inflammation and oxidative damage, and promoting tissue repair. \"Hewei Jiangni\" formulas (harmonizing the stomach and directing rebellious Qi downward), including Xiao-Ban-Xia-Tang, ginger, and external therapies (e.g., acupuncture, moxibustion, acupoint application) directly alleviate nausea and vomiting by regulating gastrointestinal motility, antagonizing emesis-related receptors, and inhibiting inflammatory pathways. Clinical research shows that combining TCM with conventional antiemetic regimens improves the control of delayed CINV and enhances patients' quality of life, while maintaining a favorable safety profile. However, current evidence remains limited by small sample sizes, insufficient mechanistic investigations, and lack of standardized treatment plans. Future research should prioritize high-quality and large-sample clinical trials and clarify its mechanism of action using modern scientific approaches, so as to promote the standardized and efficient application of TCM for the prevention and treatment of CINV.",

One hundred fifty participants in the AIBL study underwent both 18F-Florbetapir (FBP) and NAV A\u03b2 PET scans. PET scans were assessed by six nuclear medicine physicians against Centiloid (CL) quantification. An optimized reference region was utilized for FBP as it improved CL-visual read correlations. Inter-reader agreement of visual assessment was measured using Fleiss' Kappa. Mean peak accuracy for visual read exceeded 95% for both NAV and FBP. However, peak accuracy for NAV visual reads was achieved at 14-15CL compared to 38-46CL for FBP. Higher inter-reader agreement was observed for NAV compared to FBP. For mild to moderate elevation in A\u03b2, visual read of NAV is more sensitive and consistent than visual read of FBP by both experienced and novice readers.",
        "42491134": "ID: 42491134\nTitle: Epitranscriptomic regulation by m6A in immunity and autoimmune disorders: emerging mechanisms and clinical perspectives.\nAbstract: Immune-mediated diseases arise from intricate interactions among genetic, environmental, and epigenetic factors that disrupt immune homeostasis. In recent years, epigenetic mechanisms have been widely explored as critical factors in autoreactivity. Among these modifications, N6-methyladenosine (m6A) RNA methylation stands out as a pivotal post-transcriptional regulator of immune cell function and autoimmune diseases (ADs) progression. This review outlines m6A regulation in immune microenvironments and its dual role in maintaining tolerance and promoting inflammation. This study highlights how m6A regulators, including writers (METTL3/14), erasers (FTO and ALKBH5), and readers (YTHDF1-3 and IGF2BP3), orchestrate immune cell dysfunction across systemic (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriasis) and organ-specific (multiple sclerosis (MS), inflammatory bowel disease (IBD), type 1 diabetes mellitus (T1DM), and autoimmune thyroid disease (AITD) ADs, revealing disease-specific epitranscriptomic regulatory patterns. Critically, we highlight recent therapeutic breakthroughs targeting m6A regulators, including METTL3 inhibition (STM2457) for Th17-driven MS and RA synovitis, ALKBH5 modulation (ALK-04) to mitigate psoriasis flares and neuroinflammation, FTO-targeting small molecules (Rhein) to prevent RA-associated bone erosion, and IGF2BP3 blockade (triptolide) to suppress RA fibroblast activity. Despite their promise, key challenges persist, including stage-specific effects (early vs. chronic), rare immune subset targeting (MDSCs in AIH), and concerns about the long-term safety of epitranscriptomic drugs. Future studies must address m6A dynamics in immune crosstalk to advance precision medicine strategies, particularly through combinatorial approaches with existing JAK inhibitors or checkpoint modulators.",
        "42491177": "ID: 42491177\nTitle: From metabolism to genome integrity: NRF2 as a key mediator of cancer therapy response.\nAbstract: Metabolic rewiring in cancer is sustained by deregulated intracellular signaling, frequently due to genetic mutation of oncogenes, tumor suppressors or oncometabolite genes. These mutations strongly affect the activity of Transcription Factors (TFs) and epigenetic remodelling factors, ultimately leading to different metabolic subtypes. Of note, several metabolites have been proposed to significantly modulate gene expression through post-translational modifications of metabolic enzymes, TFs and histones, sustaining the intracellular feedback loop in cancer cells. Among the TFs involved in metabolic reprogramming of cancer cells, NRF2, a well-characterized factor in the oxidative stress response, emerged as a crucial player. NRF2 is at the crossroads of critical intracellular pathways linking metabolism, DNA damage and chromatin remodelling. These findings point to NRF2 as a pivotal player in cancer therapy resistance, making it a promising target to ameliorate patient survival. Remarkably, high expression and transcriptional activity of NRF2 have been demonstrated in several cancer types, where its expression and activity correlate with poor patient survival. Unfortunately, direct molecular targeting of TFs is still challenging. Therefore, identifying signaling pathways that either drive NRF2 deregulation or are sustained by its hyperactivation has emerged as an alternative strategy to enhance NRF2 targetability and ultimately improve therapeutic outcomes. Here, we aim to summarize the current knowledge on the role of NRF2 in resistance to cancer therapy, focusing on its regulation of gene expression, metabolism, and immune response in cancer, while exploring potential functional links between metabolic rewiring, chromatin remodelling and DNA damage response proficiency.",
        "42491221": "ID: 42491221\nTitle: Acupuncture-induced HSP70 upregulation in neuroprotection: mitochondrial and anti-apoptotic mechanisms.\nAbstract: Heat shock protein 70 (HSP70) represents a major stress-inducible chaperone, holding considerable significance in regulating the proteostasis, mitochondrial homeostasis, and apoptosis in the injured nervous system. Acupuncture has shown neuroprotective effects in multiple models of neurological diseases, yet the role of HSP70 as a mechanistic link between acupuncture stimulation and neuronal protection has not been systematically clarified. To this end, current evidence on acupuncture-induced HSP70 regulation is hereby summarized, and its potential contribution to neuroprotection is accordingly discussed, with particular emphasis on mitochondrial preservation and anti-apoptotic signaling. Available studies suggest that acupuncture-associated HSP70 upregulation is linked to enhanced cellular stress adaptation, reduced oxidative injury, stabilization of Bcl-2 family-dependent mitochondrial integrity, inhibition of cytochrome c release and apoptosome formation, and suppression of downstream caspase activation. In addition to these intracellular effects, emerging evidence also uncovers the involvement of HSP70 in neuroinflammatory regulation and neuron-glia communication, suggesting its broader role in shaping the injured neural microenvironment. However, current evidence remains largely associative, leaving several key issues unresolved, including questions of causal necessity, cell-specific regulation, intercellular trafficking, and neuroimmune integration. Overall, HSP70 may represent a promising integrative mediator of acupuncture-induced neuroprotection, yet its precise mechanistic function still warrants further experimental validation.",

To explore potential immune alterations associated with PD, we analyzed plasma antibody responses against a panel of viral and host synthetic linear epitopes in PD patients (n = 50) and healthy controls (HCs) (n = 54). Antibody levels against Interferon Regulatory Factor 5 (IRF5), Cathepsin B (CTSB), L-asparaginase (ASRGL1), Human Endogenous Retrovirus type K (HERV-K), Interferon-\u03b1 (IFN-\u03b1), Interferon- \u03c9 (IFN-\u03c9), \u03b1-synuclein, Herpes Simplex Virus type 1 (HSV-1), olfactory receptor proteins (OLF-R), and Dickkopf-related protein 3 (DKK3) were measured. PD patients showed significantly higher antibody levels against IRF5, CTSB, ASRGL1, and HSV-1 compared with controls, while antibodies against HERV-K were significantly lower. No differences were observed for IFN-\u03b1, IFN-\u03c9, \u03b1-synuclein, OLF-R, or DKK3. Correlation analysis revealed several associations among antibody responses. IRF5 antibodies correlated positively with CTSB, ASRGL1, HERV-K, IFN-\u03b1, IFN-\u03c9, and HSV-1. CTSB correlated with IFN-\u03b1, IFN-\u03c9, HSV-1, OLF-R, and DKK3, while ASRGL1 correlated with HERV-K and IFN-\u03c9. IFN-\u03b1 correlated with IFN-\u03c9, HSV-1, and DKK3, and IFN-\u03c9 correlated with HSV-1 and DKK3. HSV-1 antibodies were also associated with OLF-R and DKK3. Notably, HERV-K antibodies showed a negative correlation with DKK3. Stratification analyses indicated that antibody levels against HERV-K were higher in patients with milder disease stages accordingly with Hoehn and Yahr scale (HY 1-4) compared with HY 5, whereas IFN-\u03b1 antibodies were increased in HY5 patients. Female patients generally showed lower antibody levels than males for different targets. No differences were observed according to disease duration. Overall, these findings indicate that PD patients display selective changes in antibody responses involving antiviral and host proteins. These targets may represent potential biomarkers of immune alterations in PD, although further studies are required to clarify the underlying biological mechanisms.",
        "42491765": "ID: 42491765\nTitle: Glabridin ameliorates oxidative stress and inflammation in a bovine intestinal cell line and a colitis mouse model.\nAbstract: Oxidative stress (OS) adversely affects the intestinal health and mucosal barrier function in dairy cows. Glabridin (Glab), a natural flavonoid derived from licorice, has been shown to mitigate stress-related damage due to its antioxidant properties. This study aims to assess the impact of Glab on OS-induced damage in the bovine immortalized cell line (BIECs-21), validate its effectiveness in vivo, and elucidate the underlying mechanisms. The in vitro OS model of BIECs-21 was established using 400 \u03bcM H2O2. The study evaluated cell viability, lactate dehydrogenase (LDH) activity, oxidative markers, inflammatory responses, and apoptosis in BIECs-21 under various treatment conditions. Additionally, the effects of Glab were investigated in a murine model of experimental colitis induced by dextran sulfate sodium (DSS). Glab improved cell viability, reduced LDH release, and mitigated the adverse effects of H2O2 on total anti-oxidation capacity (T-AOC), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) levels. qRT-PCR analysis revealed that H2O2 exposure resulted in decreased expression of nuclear factor erythroid 2-related factor 2 (Nrf2), superoxide dismutase 1 (SOD1), NADPH quinine oxidoreductase-1 (NQO1), and heme oxygenase-1 (HO-1), while it increased the expression of nuclear factor-kappa B (NF-\u03baB), tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-6 (IL-6), and interleukin-8 (IL-8), ultimately leading to apoptosis in BIECs-21. Notably, Glab supplementation partially reversed these effects. Similar benefits of Glab were observed in a DSS-induced colitis mouse model. Glab reduces OS-induced apoptosis in vitro and in vivo by enhancing antioxidant capacity and reducing inflammation.",

Utilizing the indazole heterocycle-a scaffold known for its structural plasticity and multi-target potential-as the core structure, a series of derivatives were designed and synthesized with the aim of screening and elucidating their anti-inflammatory activity and underlying mechanisms. The activities of the compounds were systematically evaluated in an in vitro LPS-stimulated BV-2 microglial model using Griess assay, MTT assay, qPCR, and western blotting. Among the 15 derivatives obtained, compound 5o exhibited the most potent anti-inflammatory activity (IC50 = 8.45 \u00b1 0.64 \u03bcM). Its mechanism of action involves the regulation of microglial polarization-significantly suppressing M1 phenotype markers such as NO, IL-1\u03b2, IL-6, TNF-\u03b1, iNOS, and COX-2. Further mechanistic studies revealed that this effect is mediated through positive regulation nuclear translocation of Nrf2. In summary, this study demonstrates that the indazole derivative 5o exerts anti-neuroinflammatory effects by inhibiting microglial M1 polarization, providing a promising lead compound and a robust pharmacological basis for the development of novel therapeutic strategies targeting neuroinflammatory diseases.",
        "42492072": "ID: 42492072\nTitle: Examining Mgat5 upregulation's protective effects and underlying mechanisms in spinal cord injury.\nAbstract: Secondary inflammation severely hinders recovery after spinal cord injury (SCI). This study investigates whether boosting Mgat5-mediated N-glycosylation via a lentiviral vector can reprogram the local immune microenvironment and foster functional repair. We engineered a lentiviral vector to overexpress Mgat5 (Lv-Mgat5) and validated it in rat dorsal root ganglion cells. Next, we established a contusion SCI model in rats, dividing them into sham, SCI, MP (methylprednisolone), Lv-vector, and Lv-Mgat5 groups. Motor recovery was evaluated using BBB and inclined plane tests. To uncover the mechanisms, we quantified N-glycan branching (PHA-L precipitation), inflammatory cytokines (ELISA), and regeneration markers (Western blot). Lv-Mgat5 effectively upregulated \u03b2-1,6-GlcNAc branching both in vitro and in vivo without cytotoxicity. Importantly, this targeted intervention modulated the injured spinal cord microenvironment toward an anti-inflammatory profile. We observed a significant drop in TNF-\u03b1 and IL-1\u03b2, alongside a surge in IL-10 (p\u2009<\u20090.05). Furthermore, GAP-43 expression remained robustly elevated. Consequently, rats treated with Lv-Mgat5 showed remarkable and sustained improvements in hindlimb motor function compared to vehicle controls (p\u2009<\u20090.01). Targeted Mgat5 upregulation effectively modulates the post-injury microenvironment. By reshaping the N-glycosylation profile, it attenuates secondary neuroinflammation and supports a regeneration-associated molecular response, offering a promising target for gene therapy after SCI."
