However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts.

"abstract_text": "ID: 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."

"abstract_text": "ID: 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."

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."

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."

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."

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."

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."

C57BL/6 mice were randomly divided into control (PBS), MNU-induced RP, and MNU+EGCG pretreatment groups. EGCG (50 mg/kg, intraperitoneal) was administered daily for 3 consecutive days prior to a single MNU injection (50 mg/kg). Retinal function was evaluated by scotopic electroretinography (ERG). Retinal structure was assessed using optical coherence tomography (OCT) and hematoxylin-eosin staining, with outer nuclear layer (ONL) thickness measurement. Mechanisms were explored via RNA sequencing, reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) validation of oxidative stress- and inflammation-related genes, and immunohistochemistry for microglial activation, astrocytic gliosis, and apoptosis markers. Compared with the MNU group, EGCG pretreatment significantly preserved scotopic ERG a-wave and b-wave amplitudes (P<0.001). OCT and histological analysis showed that EGCG markedly attenuated MNU-induced thinning of total retina and ONL (P<0.005, P<0.001, respectively). RNA sequencing identified 1147 differentially expressed genes modulated by EGCG, with significant upregulation of antioxidant genes (Nrf2, Sod1, Gpx4, Cat1, Ho-1) and downregulation of pro-inflammatory genes. Immunohistochemistry confirmed that EGCG significantly reduced microglial activation, glial fibrillary acidic protein (GFAP) expression, and cleaved caspase-3-positive cells (P<0.01 to P<0.001). EGCG exerts robust neuroprotective effects in MNU-induced RP through enhancement of antioxidant defenses, suppression of neuroinflammation, and preservation of retinal structure and function. These findings suggest EGCG as a promising candidate for adjuvant antioxidant therapy in RP."

Bax inhibitor 1 (BI1), an endoplasmic reticulum protein downregulated in ALS neuroprotective, represents a therapeutic target, but its metabolic regulatory mechanisms are incompletely understood. Using transcriptomics in skeletal muscle of ALS mice pre- and post-BI1 treatment, we identified BI1-regulated pathways. Structure-based virtual screening of FDA-approved compounds nominated lisinopril as a BI1 activator. Lisinopril upregulated BI1 protein expression, stabilizing mitochondrial membrane potential and protecting against SOD1G93A-induced apoptosis in NSC34 cells. Concurrently, it regulated TGF-\u03b21/mTOR-dependent autophagy, maintained NMJ integrity, and reshaped triglyceride/sphingolipid/glycerophospholipid metabolism to attenuate spinal cord pathology in ALS mice, promoting energy metabolism shift toward glucose oxidation. Additionally, lisinopril inhibited the TGF-\u03b21/Smad2/3 pathway to alleviate muscle fibrosis, downregulate Acp5/FN expression, and reduce type I collagen deposition. In conclusion, this study provides evidence that pharmacological activation of BI1 by lisinopril suppresses TGF-\u03b21, modulates lipid metabolism, and ameliorates ALS pathology, demonstrating promising therapeutic repurposing potential."

Rosmarinic acid (RA), a polyphenolic compound with antioxidant and neuroprotective properties, has not yet been evaluated for mitigating ISO-induced toxicity. In this study, Wistar albino rat pups were exposed to ISO (1.5% in 30% oxygen/air, 3-h) on postnatal days (P)7\u202f+P9\u202f+\u202fP11, and the protective effects of intranasal RA (25\u202fmg/kg) pretreatment (1-h before anesthesia) were investigated for the first time. Control groups received either oxygen alone or RA before oxygen exposure. On P12, hippocampal tissue was examined for detecting acute neuronal apoptosis, oxidative stress, inflammation, and stress-related proteins using histopathology and immunoblotting. Cognitive performance was assessed using Morris Water Maze tests that evaluated spatial learning (P28-P32) and both short- and long-term memory (P33, P60, P90). Repeated ISO exposure impaired learning and memory, increased anxiety-like behaviors, and caused hippocampal damage, along with elevated pro-apoptotic markers (Bax/Bcl-2 ratio, cleaved caspase-3, PARP1 fragments), redox imbalance and inflammation (reduced SOD1; increased GPX1, 4HNE, NF-\u03baB-p65, TNF-\u03b1). ISO also disrupted stress signaling by reducing p-HSF1, Hsp90, and Hsp60 levels, while raising Hsp70 and decreasing 14-3-3 isoforms. RA pretreatment countered these effects by restoring antioxidant and stress-response proteins, reducing inflammation and apoptosis, and maintaining neuronal integrity and cognitive function. No harmful effects were observed in the RA-only group. These findings suggest that intranasal RA pretreatment may be a preventive strategy against anesthesia-related neurotoxicity in pediatric patients."

Thus, novel synthetic quercetin derivatives (QDs) with improved properties and/or drug combinations should be designed and tested. In the present study, anticancer activity of fourteen newly synthesized QDs was investigated using four cellular models of melanoma, namely A375, MM370, G-361, and SH-4 cells. Thioquercetins (thioQ, thioQ(OAc)4, and thioQ(OAc)5), when used at low micromolar range, induced apoptotic cell death in melanoma cells compared to normal cells. Thioquercetins also reduced the population of spheroid-forming cells and suppressed the growth of A375 cells in 3D spheroid models. Thioquercetin-mediated antimelanoma action was potentiated upon heat shock protein 90 (HSP90) inhibition. Co-treatment with the HSP90 inhibitor 17-DMAG and thioquercetins augmented oxidative stress (increased superoxide production, decreased levels of antioxidant proteins SOD1, and PRDX1-2), and impaired the aryl hydrocarbon receptor (AhR)/cytochrome P450 1A1 (CYP1A1) signaling pathway-based detoxification of thioquercetins by the inhibition of AhR translocation to the nucleus and AhR-mediated stimulation of CYP1A1 expression leading to enhanced cytotoxic effects against melanoma cells. The senolytic activity of thioQ(OAc)4 with four acetylated hydroxy groups against cisplatin-induced senescent melanoma cells was also revealed in selected experimental settings. We suggest that the use of novel thioquercetin-based derivatives along with HSP90 inhibitors should be further validated in vivo and considered for the design of more effective antimelanoma strategies in the future."

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.

Peripheral blood samples were collected from ALS patients and healthy controls (HC) to establish the iPSC-derived motor neurons (MNs). Whole-cell patch-clamp recordings at different culture stages was made using an Axopatch 700B amplifier in combination with pClamp 11 software (Molecular Devices). The frequency of action potentials (APs) was recorded. Additionally, Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) Nick-End Labeling (TUNEL) was used to assess the apoptosis of MNs. ALS patient-derived MNs exhibited significantly higher firing rates compared to HCs at both 4-7 weeks (p = 0.004) and 7-9 weeks (p = 0.009). Further analysis revealed that SOD1-derived MNs showed significantly higher firing frequencies than sALS (p = 0.009) and HCs (p < 0.001) in 4-7 weeks.

NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS.

Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated 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."

Peripheral blood samples were collected from ALS patients and healthy controls (HC) to establish the iPSC-derived motor neurons (MNs). Whole-cell patch-clamp recordings at different culture stages was made using an Axopatch 700B amplifier in combination with pClamp 11 software (Molecular Devices). The frequency of action potentials (APs) was recorded. Additionally, Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) Nick-End Labeling (TUNEL) was used to assess the apoptosis of MNs. ALS patient-derived MNs exhibited significantly higher firing rates compared to HCs at both 4-7 weeks (p = 0.004) and 7-9 weeks (p = 0.009). Further analysis revealed that SOD1-derived MNs showed significantly higher firing frequencies than sALS (p = 0.009) and HCs (p < 0.001) in 4-7 weeks. In 7-9 weeks, it remained significant between SOD1 and HC-derived MNs (p = 0.015), but became insignificant between SOD1 and sALS (p = 0.855).

MNs derived from both patients with mutant SOD1 and sporadic ALS exhibited increased excitability compared to HCs. The increased excitability of MNs derived from ALS patients with mutant SOD1 occurred earlier, and over time, became consistent with the excitability observed in MNs derived from sporadic ALS. The apoptosis rates of MNs showed similar trends. iPSC-derived MNs from both sporadic and mutant ALS may serve as useful cell models for ALS in future studies."

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."

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."

C57BL/6 mice were randomly divided into control (PBS), MNU-induced RP, and MNU+EGCG pretreatment groups. EGCG (50 mg/kg, intraperitoneal) was administered daily for 3 consecutive days prior to a single MNU injection (50 mg/kg). Retinal function was evaluated by scotopic electroretinography (ERG). Retinal structure was assessed using optical coherence tomography (OCT) and hematoxylin-eosin staining, with outer nuclear layer (ONL) thickness measurement. Mechanisms were explored via RNA sequencing, reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) validation of oxidative stress- and inflammation-related genes, and immunohistochemistry for microglial activation, astrocytic gliosis, and apoptosis markers. Compared with the MNU group, EGCG pretreatment significantly preserved scotopic ERG a-wave and b-wave amplitudes (P<0.001). OCT and histological analysis showed that EGCG markedly attenuated MNU-induced thinning of total retina and ONL (P<0.005, P<0.001, respectively). RNA sequencing identified 1147 differentially expressed genes modulated by EGCG, with significant upregulation of antioxidant genes (Nrf2, Sod1, Gpx4, Cat1, Ho-1) and downregulation of pro-inflammatory genes. Immunohistochemistry confirmed that EGCG significantly reduced microglial activation, glial fibrillary acidic protein (GFAP) expression, and cleaved caspase-3-positive cells (P<0.01 to P<0.001). EGCG exerts robust neuroprotective effects in MNU-induced RP through enhancement of antioxidant defenses, suppression of neuroinflammation, and preservation of retinal structure and function. These findings suggest EGCG as a promising candidate for adjuvant antioxidant therapy in RP."

Bax inhibitor 1 (BI1), an endoplasmic reticulum protein downregulated in ALS neuroprotective, represents a therapeutic target, but its metabolic regulatory mechanisms are incompletely understood. Using transcriptomics in skeletal muscle of ALS mice pre- and post-BI1 treatment, we identified BI1-regulated pathways. Structure-based virtual screening of FDA-approved compounds nominated lisinopril as a BI1 activator. Lisinopril upregulated BI1 protein expression, stabilizing mitochondrial membrane potential and protecting against SOD1G93A-induced apoptosis in NSC34 cells. Concurrently, it regulated TGF-\u03b21/mTOR-dependent autophagy, maintained NMJ integrity, and reshaped triglyceride/sphingolipid/glycerophospholipid metabolism to attenuate spinal cord pathology in ALS mice, promoting energy metabolism shift toward glucose oxidation. Additionally, lisinopril inhibited the TGF-\u03b21/Smad2/3 pathway to alleviate muscle fibrosis, downregulate Acp5/FN expression, and reduce type I collagen deposition. In conclusion, this study provides evidence that pharmacological activation of BI1 by lisinopril suppresses TGF-\u03b21, modulates lipid metabolism, and ameliorates ALS pathology, demonstrating promising therapeutic repurposing potential."

Rosmarinic acid (RA), a polyphenolic compound with antioxidant and neuroprotective properties, has not yet been evaluated for mitigating ISO-induced toxicity. In this study, Wistar albino rat pups were exposed to ISO (1.5% in 30% oxygen/air, 3-h) on postnatal days (P)7\u202f+P9\u202f+\u202fP11, and the protective effects of intranasal RA (25\u202fmg/kg) pretreatment (1-h before anesthesia) were investigated for the first time. Control groups received either oxygen alone or RA before oxygen exposure. On P12, hippocampal tissue was examined for detecting acute neuronal apoptosis, oxidative stress, inflammation, and stress-related proteins using histopathology and immunoblotting. Cognitive performance was assessed using Morris Water Maze tests that evaluated spatial learning (P28-P32) and both short- and long-term memory (P33, P60, P90). Repeated ISO exposure impaired learning and memory, increased anxiety-like behaviors, and caused hippocampal damage, along with elevated pro-apoptotic markers (Bax/Bcl-2 ratio, cleaved caspase-3, PARP1 fragments), redox imbalance and inflammation (reduced SOD1; increased GPX1, 4HNE, NF-\u03baB-p65, TNF-\u03b1). ISO also disrupted stress signaling by reducing p-HSF1, Hsp90, and Hsp60 levels, while raising Hsp70 and decreasing 14-3-3 isoforms. RA pretreatment countered these effects by restoring antioxidant and stress-response proteins, reducing inflammation and apoptosis, and maintaining neuronal integrity and cognitive function. No harmful effects were observed in the RA-only group. These findings suggest that intranasal RA pretreatment may be a preventive strategy against anesthesia-related neurotoxicity in pediatric patients."

Thus, novel synthetic quercetin derivatives (QDs) with improved properties and/or drug combinations should be designed and tested. In the present study, anticancer activity of fourteen newly synthesized QDs was investigated using four cellular models of melanoma, namely A375, MM370, G-361, and SH-4 cells. Thioquercetins (thioQ, thioQ(OAc)4, and thioQ(OAc)5), when used at low micromolar range, induced apoptotic cell death in melanoma cells compared to normal cells. Thioquercetins also reduced the population of spheroid-forming cells and suppressed the growth of A375 cells in 3D spheroid models. Thioquercetin-mediated antimelanoma action was potentiated upon heat shock protein 90 (HSP90) inhibition. Co-treatment with the HSP90 inhibitor 17-DMAG and thioquercetins augmented oxidative stress (increased superoxide production, decreased levels of antioxidant proteins SOD1, and PRDX1-2), and impaired the aryl hydrocarbon receptor (AhR)/cytochrome P450 1A1 (CYP1A1) signaling pathway-based detoxification of thioquercetins by the inhibition of AhR translocation to the nucleus and AhR-mediated stimulation of CYP1A1 expression leading to enhanced cytotoxic effects against melanoma cells. The senolytic activity of thioQ(OAc)4 with four acetylated hydroxy groups against cisplatin-induced senescent melanoma cells was also revealed in selected experimental settings. We suggest that the use of novel thioquercetin-based derivatives along with HSP90 inhibitors should be further validated in vivo and considered for the design of more effective antimelanoma strategies in the future."

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."

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."

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."

Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS."

NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies."

The best-established histopathological sequence involves AL-related epithelial apoptosis, phagocytosis of apoptotic bodies by macrophages, and subsequent lipofuscin deposition. Emerging evidence suggests that the gut microbiota (GM) may contribute to this process by converting pharmacologically inactive anthraquinone glycosides into active anthrone metabolites, including rhein anthrone. This narrative review summarizes available MC-specific findings and clearly distinguishes them from mechanistic hypotheses extrapolated from constipation, intestinal barrier, and microbiome literature. We discuss microbial \u03b2-glucosidases and reductases involved in AL biotransformation, reported changes in microbial diversity and SCFA-producing taxa in MC or constipation-associated cohorts, and plausible links with barrier dysfunction, bile-acid metabolism, tryptophan-derived metabolites, and LPS-TLR4 signaling. We therefore present the \"Microbiota-Apoptosis Axis\" as a proposed framework rather than a validated causal pathway. Finally, we review GM-targeted strategies, including probiotics, synbiotics, and fecal microbiota transplantation, while emphasizing that direct clinical evidence in MC remains limited and that cessation of anthraquinone laxatives remains the primary management strategy."

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."

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."

"abstract_text": "ID: 42054746\nTitle: From necroptosis to neuroinflammation: Unraveling mechanisms and therapeutic targets in age-related cognitive decline.\nAbstract: Aging is the major risk factor for several chronic conditions, including cognitive decline and dementia. It is accompanied by profound immune alterations characterized by a progressive decline in immune competence, a process known as immunosenescence. The resulting dysregulation of immune function leads to the overproduction of proinflammatory cytokines and fuels a persistent, low-grade inflammatory state termed inflammaging. This chronic inflammation contributes to dysfunction across the central and peripheral nervous systems, promoting neuronal damage and accelerating neurodegenerative processes such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and other age-related cognitive disorders. Within this framework, prolonged activation of inflammatory pathways can trigger regulated forms of cell death. Among these, necroptosis has recently emerged as a potential mediator linking inflammaging to neurodegeneration. Its core molecular effectors, including the receptor-interacting protein kinases RIPK1 and RIPK3 and the mixed-lineage kinase domain-like protein (MLKL), are increasingly expressed in aged neural tissues, promoting the release of damage-associated molecular patterns (DAMPs) that amplify glial activation, oxidative stress, and blood-brain barrier disruption. Growing evidence suggests that necroptotic signaling may be upregulated in the aging brain and in neurodegenerative disorders, where it could contribute to neuronal loss and cognitive impairment. This review discusses the potential role of necroptosis in the continuum between inflammation and neurodegeneration, highlighting emerging diagnostic and therapeutic perspectives. Epigenetic and circulating biomarkers, such as phosphorylated MLKL and specific microRNAs, may support early detection, while pharmacological and nutraceutical strategies targeting necroptosis show promising neuroprotective effects in preclinical studies."

Evidence has shown that degeneration of cutaneous nerves may reflect neurodegenerative processes occurring within the central nervous system. Although skin biopsy is widely adopted in clinical practice, the procedure is invasive and requires multiple patients' tissue removals. Therefore, we developed a 3D innervated skin model by combining 3D printing of methacrylated hyaluronic acid as an innovative tool for better reproducing the dermis and epidermis and electrospinning of polylactic acid for mimicking skin innervation. Later, 3D artificial skin was colonized with a preneuronal cell line (SH-SY5Y) and fibroblasts isolated from skin biopsy of ALS patients at different disease stages. 3D skin possesses a porosity suitable for cell colonization and a high stability. Importantly, biological results reveal an increase of TAR DNA-binding protein 43 aggregates, NOD-like receptor pyrin domain containing protein 3, interleukin (IL)-18, IL-6, and nitrites in 3D skin of ALS patients, thus indicating pyroptosis activation linked to neurodegeneration.

However, the mechanism by which TDP-43 pathology disrupts microglial function and drives neuroinflammation remains unclear. In this study, we demonstrated that cytoplasmically mis-localized TDP-43 exacerbated neuroinflammation, induced cell death, and impaired phagocytic function in microglial cells, primarily through receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis. Pharmacological inhibition of RIPK3 with GSK872 markedly attenuated these pathological effects in vitro. These findings were further corroborated in a murine model with cytoplasmic TDP-43 mis-localization, where GSK872 treatment remarkably alleviated neuroinflammation and restored cognitive deficits. Mechanistically, our findings indicate that the nuclear depletion of TDP-43, resulted from its cytoplasmic mis-localization, impairs its ability to transcriptionally repress the Ripk3 gene, subsequently leading to RIPK3 upregulation and activation of RIPK3-dependent necroptosis. Collectively, our findings establish RIPK3-dependent necroptosis as a critical driver of TDP-43 pathology-mediated neuroinflammation and identified necroptosis as a promising therapeutic target in TDP-43-associated neurodegenerative disorders."

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.

Human AML MOLM-13 cells were treated with gradient concentrations (0, 120, 240, 480 \u03bcmol/L) of loganetin for 48 hours. CDK2 protein expression and its interaction with KLHL6 were analyzed by Western blot and co-immunoprecipitation (Co-IP), respectively. Cellular morphology was observed via Giemsa staining.

We hypothesized that a 2.5\u2009Gy dose would induce mitotic failure and cell death, whereas low doses (<1\u2009Gy) might elicit adaptive or hormetic responses. Human U-87\u2009MG glioblastoma cells were cultured on coated glass-bottom dishes, stained with Hoechst 33,342, and maintained at 37\u00b0C/5% CO\u2082. A custom agarose phantom with an embedded dish and metal grid enabled precise delivery of graded SRS doses. CT-based planning localized the dish in the Leksell Gamma Knife Perfexion\u00ae. A single 50% isodose shot delivered 2.5\u2009Gy at the central grid cell (C9), generating adjacent compartments with 2.0, 1.5, 1.0, 0.8, and 0.5\u2009Gy. Live confocal imaging was performed at baseline and at 0, 3, 6, and 24\u2009h post-irradiation. Total cell number and mitotic cells (condensed chromosomes) were quantified per field. Three independent experiments were analyzed using two-way ANOVA with Tukey's post hoc test (\u03b1\u2009=\u20090.05). At 2.5\u2009Gy, cell numbers declined to near zero by 6\u2009h (Mean normalized adherent nuclear count decreased to approximately 5% of baseline.), associated with marked nuclear abnormalities, including multinucleation and nuclear fragmentation. Mitotic figures were absent at all post-SRS time points. Intermediate doses (1.0-1.5\u2009Gy) caused a transient delay: cell counts increased (up to ~150% at 3-6\u2009h, p\u2009<\u20090.05) before declining by 24\u2009h. In contrast, low doses (0.5-0.8\u2009Gy) resulted in net proliferation. The 0.8\u2009Gy group showed a 182% increase in cell count at 24\u2009h (p\u2009=\u20090.01), with a peak mitotic fraction (~12%) at 6\u2009h versus ~2% in controls (p\u2009<\u20090.01). These findings are consistent with radiation hormesis. Two-way ANOVA confirmed significant effects of dose and time (p\u2009<\u20090.001). To our knowledge, this is the first study integrating live-cell imaging with GKRS isodose mapping to assess temporal cellular responses to stereotactic radiosurgery. Gamma Knife SRS induces a dose-dependent response in GBM cells: high doses abolish proliferation, whereas sub-therapeutic doses paradoxically stimulate cell-cycle progression. These findings highlight a potential clinical concern, as low-dose regions may transiently promote tumor growth, but may also be exploited to enhance radiosensitivity."

In the present study, we explored the effects and underlying mechanisms of SiNPs exposure during in vitro maturation (IVM) of porcine oocytes. The results showed that SiNPs significantly suppress porcine oocyte maturation as evidenced by decreased first polar body (PB1) release rate. Notably, SiNPs significantly induced abnormal expansion of cumulus cells and impaired gap junction intercellular communication (GJIC), accompanied by decreased Connexin 43 (CX43) expression and aberrant F-actin structure. Furthermore, DCFH-DA staining showed that SiNPs significantly increased reactive oxygen species (ROS) levels and malondialdehyde (MDA) content, and decreased the mRNA levels of antioxidant-related genes, including SOD1, SOD2, CAT, GPX1, PRDX2, and NRF2. JC-1 staining showed that SiNPs significantly induced mitochondrial dysfunction via diminished mitochondrial membrane potential (\u0394\u03a8m) and aberrant distribution, and decreased the mRNA levels of energy metabolism-related genes, such as NOX4 and COX2. Additionally, SiNPs significantly disrupted lysosomal function and cholesterol trafficking and decreased the mRNA levels of LDLR, NPC1, NPC2, and LAMP2, leading to reduced free cholesterol levels and the mRNA levels of estrogen synthesis-related genes, including STAR, CYP19A1, and HSD-3\u03b2. Collectively, SiNPs suppress porcine oocyte maturation, at least partly, through oxidative stress, metabolic disruption, and impaired cholesterol trafficking."

This study investigated the impact of 28 consecutive days of 5-lx ALAN exposure on hippocampal function in C57BL/6\u00a0J mice. We evaluated locomotor behavior, neuronal morphology, neurogenesis, oxidative stress, and circadian rhythms, revealing that ALAN induces cognitive impairment. ALAN exposure reduced Bmal1 expression, increased reactive oxygen species (ROS) and malondialdehyde accumulation, and disrupted the time-of-day-dependent differences expression of NRF2, SOD1, and GPX1. These alterations suppressed SOD and GPX enzymatic activity, leading to hippocampal oxidative damage. To clarify BMAL1's role, we used adeno-associated virus (AAV) to modulate Bmal1 expression in the hippocampus. ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression. These findings suggest that ALAN can contribute to memory impairment by disrupting hippocampal damage and impairing neurogenesis through its effect on Bmal1. This study identifies potential molecular targets for preventing and treating cognitive impairment and neurodegenerative disorders."

The ciliate Paramecium tetraurelia exhibits nuclear dimorphism, harboring two germline micronuclei (MICs) and one somatic macronucleus (MAC) within a single cell during vegetative growth. During sexual reproduction, the MICs undergo meiosis and the MAC deforms and fragments, providing a unique model to study the regulation of diverse nuclear events. Transcription factor DP (TFDP), which heterodimerizes with E2Fs, can bind to specific DNA motifs in promoters of cell cycle-regulated genes to activate or repress their expression. Here, we identified 16 TFDP homologs in P. tetraurelia, representing an exceptional gene family expansion accompanied by functional domain diversification. The functions of Tfdp1a and Tfdp1b, which are specifically expressed during sexual reproduction and localize in the old and new MACs, were further investigated. Their depletion resulted in meiotic arrest at metaphase in the MIC, failure of old MAC fragmentation, and abortive cytokinesis. Transcriptomic analysis revealed that TFDP1A/1B knockdown primarily causes gene downregulation, with\u2009>\u200960% of downregulated genes being specifically highly expressed during sexual reproduction. Functional annotation and enrichment analyses demonstrated significant downregulation of proteins involved in meiosis, DNA replication, and DNA repair. Critically, multiple downregulated meiotic regulators are essential for proper homologous chromosome segregation and sister chromatid separation, providing a mechanistic basis for the observed MIC meiotic arrest. This study uncovers Tfdp1a/1b as essential regulators of the distinctive meiotic process in P. tetraurelia, providing crucial insights into nuclear dynamics and the regulation of sexual reproduction in binucleate systems.

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."

Mounting evidence indicates that dysregulated iron metabolism and an imbalance in antioxidant defenses can induce ferroptosis in neurons and glial cells while simultaneously remodeling immune cell function, thereby establishing a bidirectional feedback loop that amplifies neuroinflammation and tissue damage. In neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), pro-inflammatory cytokines such as TNF-\u03b1 and IL-1\u03b2 released by activated microglia upregulate neuronal iron transporters (e.g., DMT1 and TfR1), promoting iron accumulation and ferroptotic cell death. In turn, damage-associated molecular patterns released from ferroptotic cells further potentiate immune activation, forming a self-amplifying cycle. In contrast, within the glioma microenvironment, CD8+ T cell-derived IFN-\u03b3 suppresses SLC7A11 expression in tumor cells, leading to glutathione depletion and glutathione peroxidase 4 inactivation, thereby triggering ferroptosis and modulating anti-tumor immunity. Although targeting ferroptosis or neuroimmune pathways has shown therapeutic promise in mitigating neurological deficits and enhancing anti-tumor responses, the underlying mechanisms governing ferroptosis-immune crosstalk remain inadequately characterized. Herein, this review systematically summarizes the key biological characteristics of ferroptosis and immune responses, with particular emphasis on their interplay across major CNS disorders (i.e., AD, PD, ALS, multiple sclerosis, stroke, and glioma). Furthermore, we discuss emerging therapeutic strategies encompassing small molecules, immunomodulatory approaches, and nanotechnology-based interventions, highlighting the ferroptosis-immune axis as a promising therapeutic target for CNS diseases."

Neurodegenerative diseases (NDs), including Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis, are characterized by oxidative stress, mitochondrial dysfunction, metabolic impairment, protein aggregation, and cytoskeletal instability-features that may provide a permissive intracellular context for disulfidptosis. However, its occurrence and pathological relevance in these disorders remain incompletely understood. In this review, we examine the potential involvement of disulfidptosis in neurodegenerative diseases from a disease-centered perspective. We emphasize that current evidence is largely indirect and based on mechanistic overlap rather than direct experimental validation in neural systems. Accordingly, we distinguish between direct evidence, indirect mechanistic support, and pathophysiological plausibility. We further discuss cell-type-specific susceptibility across neurons and glial cells, analyze its relationship with other cell death pathways, and consider potential therapeutic implications. Overall, disulfidptosis is best regarded as a context-dependent and emerging mechanism that may contribute to neuronal vulnerability under specific metabolic and redox constraints. Clarifying its disease relevance will be essential for determining its significance in neurodegeneration and its potential as a therapeutic target."

Beyond exporting Zn2+, recent evidence reveals that ZnT1 also transports Cu2+ and serves as a molecular hub linking zinc-copper interplay, redox balance, immune signaling and programmed cell death. This review summarizes current advances in ZnT1 structure, transport mechanism, regulatory networks and physiological roles across the gut-liver-immune-neuro-cardiovascular axis. We further outline its pathological involvement in Wilson disease, amyotrophic lateral sclerosis, cancer and inflammatory disorders, highlighting ferroptosis, cuproptosis and metabolic reprogramming as key downstream consequences of ZnT1 dysregulation. Emerging therapeutic approaches include small-molecule modulators, RNA-based regulation, antibody targeting and metal-based interventions. Although challenges remain-such as tissue specificity, systemic toxicity and biomarker development-ZnT1 is rapidly evolving from a basic transport protein to a promising precision medicine target. Continued efforts in structural biology, single-cell metallomics and targeted delivery systems will accelerate its clinical translation."

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."

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."

The resulting dysregulation of immune function leads to the overproduction of proinflammatory cytokines and fuels a persistent, low-grade inflammatory state termed inflammaging. This chronic inflammation contributes to dysfunction across the central and peripheral nervous systems, promoting neuronal damage and accelerating neurodegenerative processes such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and other age-related cognitive disorders. Within this framework, prolonged activation of inflammatory pathways can trigger regulated forms of cell death. Among these, necroptosis has recently emerged as a potential mediator linking inflammaging to neurodegeneration. Its core molecular effectors, including the receptor-interacting protein kinases RIPK1 and RIPK3 and the mixed-lineage kinase domain-like protein (MLKL), are increasingly expressed in aged neural tissues, promoting the release of damage-associated molecular patterns (DAMPs) that amplify glial activation, oxidative stress, and blood-brain barrier disruption. Growing evidence suggests that necroptotic signaling may be upregulated in the aging brain and in neurodegenerative disorders, where it could contribute to neuronal loss and cognitive impairment. This review discusses the potential role of necroptosis in the continuum between inflammation and neurodegeneration, highlighting emerging diagnostic and therapeutic perspectives. Epigenetic and circulating biomarkers, such as phosphorylated MLKL and specific microRNAs, may support early detection, while pharmacological and nutraceutical strategies targeting necroptosis show promising neuroprotective effects in preclinical studies."

Evidence has shown that degeneration of cutaneous nerves may reflect neurodegenerative processes occurring within the central nervous system. Although skin biopsy is widely adopted in clinical practice, the procedure is invasive and requires multiple patients' tissue removals. Therefore, we developed a 3D innervated skin model by combining 3D printing of methacrylated hyaluronic acid as an innovative tool for better reproducing the dermis and epidermis and electrospinning of polylactic acid for mimicking skin innervation. Later, 3D artificial skin was colonized with a preneuronal cell line (SH-SY5Y) and fibroblasts isolated from skin biopsy of ALS patients at different disease stages. 3D skin possesses a porosity suitable for cell colonization and a high stability. Importantly, biological results reveal an increase of TAR DNA-binding protein 43 aggregates, NOD-like receptor pyrin domain containing protein 3, interleukin (IL)-18, IL-6, and nitrites in 3D skin of ALS patients, thus indicating pyroptosis activation linked to neurodegeneration. This physiologically relevant 3D skin model reduces the need for repeated biopsies, allows standardized experimental conditions, and supports biomarker research and preclinical drug testing in ALS."

However, the mechanism by which TDP-43 pathology disrupts microglial function and drives neuroinflammation remains unclear. In this study, we demonstrated that cytoplasmically mis-localized TDP-43 exacerbated neuroinflammation, induced cell death, and impaired phagocytic function in microglial cells, primarily through receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis. Pharmacological inhibition of RIPK3 with GSK872 markedly attenuated these pathological effects in vitro. These findings were further corroborated in a murine model with cytoplasmic TDP-43 mis-localization, where GSK872 treatment remarkably alleviated neuroinflammation and restored cognitive deficits.

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."

We hypothesized that a 2.5\u2009Gy dose would induce mitotic failure and cell death, whereas low doses (<1\u2009Gy) might elicit adaptive or hormetic responses. Human U-87\u2009MG glioblastoma cells were cultured on coated glass-bottom dishes, stained with Hoechst 33,342, and maintained at 37\u00b0C/5% CO\u2082. A custom agarose phantom with an embedded dish and metal grid enabled precise delivery of graded SRS doses. CT-based planning localized the dish in the Leksell Gamma Knife Perfexion\u00ae. A single 50% isodose shot delivered 2.5\u2009Gy at the central grid cell (C9), generating adjacent compartments with 2.0, 1.5, 1.0, 0.8, and 0.5\u2009Gy. Live confocal imaging was performed at baseline and at 0, 3, 6, and 24\u2009h post-irradiation. Total cell number and mitotic cells (condensed chromosomes) were quantified per field. Three independent experiments were analyzed using two-way ANOVA with Tukey's post hoc test (\u03b1\u2009=\u20090.05). At 2.5\u2009Gy, cell numbers declined to near zero by 6\u2009h (Mean normalized adherent nuclear count decreased to approximately 5% of baseline.), associated with marked nuclear abnormalities, including multinucleation and nuclear fragmentation. Mitotic figures were absent at all post-SRS time points. Intermediate doses (1.0-1.5\u2009Gy) caused a transient delay: cell counts increased (up to ~150% at 3-6\u2009h, p\u2009<\u20090.05) before declining by 24\u2009h. In contrast, low doses (0.5-0.8\u2009Gy) resulted in net proliferation. The 0.8\u2009Gy group showed a 182% increase in cell count at 24\u2009h (p\u2009=\u20090.01), with a peak mitotic fraction (~12%) at 6\u2009h versus ~2% in controls (p\u2009<\u20090.01). These findings are consistent with radiation hormesis. Two-way ANOVA confirmed significant effects of dose and time (p\u2009<\u20090.001). To our knowledge, this is the first study integrating live-cell imaging with GKRS isodose mapping to assess temporal cellular responses to stereotactic radiosurgery. Gamma Knife SRS induces a dose-dependent response in GBM cells: high doses abolish proliferation, whereas sub-therapeutic doses paradoxically stimulate cell-cycle progression. These findings highlight a potential clinical concern, as low-dose regions may transiently promote tumor growth, but may also be exploited to enhance radiosensitivity."

In the present study, we explored the effects and underlying mechanisms of SiNPs exposure during in vitro maturation (IVM) of porcine oocytes. The results showed that SiNPs significantly suppress porcine oocyte maturation as evidenced by decreased first polar body (PB1) release rate. Notably, SiNPs significantly induced abnormal expansion of cumulus cells and impaired gap junction intercellular communication (GJIC), accompanied by decreased Connexin 43 (CX43) expression and aberrant F-actin structure.

This study investigated the impact of 28 consecutive days of 5-lx ALAN exposure on hippocampal function in C57BL/6\u00a0J mice. We evaluated locomotor behavior, neuronal morphology, neurogenesis, oxidative stress, and circadian rhythms, revealing that ALAN induces cognitive impairment. ALAN exposure reduced Bmal1 expression, increased reactive oxygen species (ROS) and malondialdehyde accumulation, and disrupted the time-of-day-dependent differences expression of NRF2, SOD1, and GPX1. These alterations suppressed SOD and GPX enzymatic activity, leading to hippocampal oxidative damage. To clarify BMAL1's role, we used adeno-associated virus (AAV) to modulate Bmal1 expression in the hippocampus. ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression. These findings suggest that ALAN can contribute to memory impairment by disrupting hippocampal damage and impairing neurogenesis through its effect on Bmal1. This study identifies potential molecular targets for preventing and treating cognitive impairment and neurodegenerative disorders."

The ciliate Paramecium tetraurelia exhibits nuclear dimorphism, harboring two germline micronuclei (MICs) and one somatic macronucleus (MAC) within a single cell during vegetative growth. During sexual reproduction, the MICs undergo meiosis and the MAC deforms and fragments, providing a unique model to study the regulation of diverse nuclear events. Transcription factor DP (TFDP), which heterodimerizes with E2Fs, can bind to specific DNA motifs in promoters of cell cycle-regulated genes to activate or repress their expression. Here, we identified 16 TFDP homologs in P. tetraurelia, representing an exceptional gene family expansion accompanied by functional domain diversification. The functions of Tfdp1a and Tfdp1b, which are specifically expressed during sexual reproduction and localize in the old and new MACs, were further investigated. Their depletion resulted in meiotic arrest at metaphase in the MIC, failure of old MAC fragmentation, and abortive cytokinesis. Transcriptomic analysis revealed that TFDP1A/1B knockdown primarily causes gene downregulation, with\u2009>\u200960% of downregulated genes being specifically highly expressed during sexual reproduction. Functional annotation and enrichment analyses demonstrated significant downregulation of proteins involved in meiosis, DNA replication, and DNA repair. Critically, multiple downregulated meiotic regulators are essential for proper homologous chromosome segregation and sister chromatid separation, providing a mechanistic basis for the observed MIC meiotic arrest. This study uncovers Tfdp1a/1b as essential regulators of the distinctive meiotic process in P. tetraurelia, providing crucial insights into nuclear dynamics and the regulation of sexual reproduction in binucleate systems.

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.

Mounting evidence indicates that dysregulated iron metabolism and an imbalance in antioxidant defenses can induce ferroptosis in neurons and glial cells while simultaneously remodeling immune cell function, thereby establishing a bidirectional feedback loop that amplifies neuroinflammation and tissue damage. In neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), pro-inflammatory cytokines such as TNF-\u03b1 and IL-1\u03b2 released by activated microglia upregulate neuronal iron transporters (e.g., DMT1 and TfR1), promoting iron accumulation and ferroptotic cell death. In turn, damage-associated molecular patterns released from ferroptotic cells further potentiate immune activation, forming a self-amplifying cycle. In contrast, within the glioma microenvironment, CD8+ T cell-derived IFN-\u03b3 suppresses SLC7A11 expression in tumor cells, leading to glutathione depletion and glutathione peroxidase 4 inactivation, thereby triggering ferroptosis and modulating anti-tumor immunity. Although targeting ferroptosis or neuroimmune pathways has shown therapeutic promise in mitigating neurological deficits and enhancing anti-tumor responses, the underlying mechanisms governing ferroptosis-immune crosstalk remain inadequately characterized. Herein, this review systematically summarizes the key biological characteristics of ferroptosis and immune responses, with particular emphasis on their interplay across major CNS disorders (i.e., AD, PD, ALS, multiple sclerosis, stroke, and glioma). Furthermore, we discuss emerging therapeutic strategies encompassing small molecules, immunomodulatory approaches, and nanotechnology-based interventions, highlighting the ferroptosis-immune axis as a promising therapeutic target for CNS diseases."

Neurodegenerative diseases (NDs), including Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis, are characterized by oxidative stress, mitochondrial dysfunction, metabolic impairment, protein aggregation, and cytoskeletal instability-features that may provide a permissive intracellular context for disulfidptosis. However, its occurrence and pathological relevance in these disorders remain incompletely understood. In this review, we examine the potential involvement of disulfidptosis in neurodegenerative diseases from a disease-centered perspective. We emphasize that current evidence is largely indirect and based on mechanistic overlap rather than direct experimental validation in neural systems. Accordingly, we distinguish between direct evidence, indirect mechanistic support, and pathophysiological plausibility. We further discuss cell-type-specific susceptibility across neurons and glial cells, analyze its relationship with other cell death pathways, and consider potential therapeutic implications. Overall, disulfidptosis is best regarded as a context-dependent and emerging mechanism that may contribute to neuronal vulnerability under specific metabolic and redox constraints. Clarifying its disease relevance will be essential for determining its significance in neurodegeneration and its potential as a therapeutic target."

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.

Although the precise pathogenesis of such diseases is complex and multifactorial, several molecular pathways have been implicated, including the aggregation of misfolded proteins, mitochondrial dysfunction, oxidative stress, neuroinflammation and disrupted iron homeostasis. Emerging evidence has underscored the pivotal role of ferroptosis, an iron\u2011dependent, non\u2011apoptotic form of cell death, in neurodegenerative disease progression. Ferritin, characterized by a 24\u2011subunit hollow sphere structure composed of heavy and light chains, plays a key role in the network regulating cerebral iron homeostasis. In response to cellular iron overload, ferritin expression is upregulated to sequester labile iron and mitigate Fenton reaction\u2011mediated toxicity, thus exerting a cytoprotective function. Paradoxically, ferritin can be degraded via ferritinophagy, a selective autophagic process that releases toxic ferrous iron and directly triggers ferroptosis.

Disruptions of MAM integrity and prolonged ER stress are well-recognized pathological features of amyotrophic lateral sclerosis (ALS), contributing to motor neuron dysfunction and degeneration. In this study, we evaluated the protective effects of pridopidine, a highly selective and potent S1R agonist currently in clinical development for Huntington's disease (HD) and ALS, using neural progenitor cells (NPCs) derived from induced pluripotent stem cells (iPSCs) from a patient with sporadic ALS. Exposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted mitochondrial membrane potential, upregulated expression of the mitochondrial apoptotic marker, BAX, increased caspase-3 activation, and reduced cell viability. Pridopidine significantly attenuated tunicamycin-induced BiP and CHOP expression in a biphasic, dose-dependent manner (with maximal efficacy at 1 \u00b5M), consistent with the typical pharmacology of S1R agonists. Pridopidine restored mitochondrial membrane potential, reduced mitochondrial apoptotic signaling, shown by decreased BAX expression and caspase-3 activation, and improved survival of ALS-NPCs under ER stress.

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 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."

DNA damage induces NAD+ loss and an increased NMN/NAD+ ratio by hyperactivating poly(ADP-ribose) polymerase 1 (PARP1), which triggers the parthanatos cell death pathway. Multiple mechanistically distinct DNA-damaging agents activate SARM1 and induce axon degeneration following PARP1 activation. Remarkably, SARM1 is required for key steps downstream of hyperactivated PARP1, which are pathognomonic of parthanatos, including mitochondrial depolarization, nuclear translocation of apoptosis-inducing factor (AIF), and cell death. Hence, SARM1 is an essential component of neuronal parthanatos. Moreover, complex neurodegenerative stimuli whose mechanisms include activation of parthanatos, such as 1-methyl-4-phenyl-pyridinium (MPP+) dopaminergic neuron toxicity and N-methyl-D-aspartate (NMDA) excitotoxicity, are potently protected by SARM1 inhibition. These findings place SARM1 at the nexus of multiple mechanisms driving neuronal cell death, thereby greatly expanding the potential clinical utility of SARM1 inhibitors beyond diseases of axon loss."

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates."

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."

This study evaluated the neuroprotective potential of caffeic acid phenethyl ester (CAPE) against MTME\u2009+\u20095-induced neurotoxicity in an ALS-like pathology model. CAPE (50 and 100\u00a0mg/kg., p.o.) demonstrated significant therapeutic efficacy by improving motor and cognitive deficits, restoring oxidative balance, and mitigating neuroinflammatory and apoptotic pathways. Behavioral assessments, including the open field, grip strength, forced swim, and Morris water maze, highlighted CAPE's ability to restore neuromuscular coordination and cognitive function in a dose-dependent manner. Cellular and Molecular analyses revealed that MTME+5 exposure significantly disrupted Klotho/SIRT-1/Nrf2/HO-1 antioxidant signaling, increased pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and elevated apoptotic markers (Bax, caspase-3) while depleting anti-inflammatory cytokines (IL-10) and neuroprotective proteins. Furthermore, CAPE treatment restored these parameters, reduced oxidative stress, and enhanced antioxidant defenses (SOD, CAT, r-GSH). Furthermore, CAPE normalized neurotransmitter imbalances, including acetylcholine, dopamine, GABA, serotonin, and glutamate, alleviating excitotoxicity. Histopathological and gross morphological analyses confirmed CAPE50 and CAPE100 ability to preserve neuronal and myelin integrity across key brain regions, including the cerebral cortex, hippocampus, striatum, midbrain, and cerebellum. CAPE also reduced methylmercury accumulation in the brain and cerebrospinal fluid, indicating detoxifying effects. Co-administration of vitamin B1 (VTB1(200)) further amplified CAPE's therapeutic efficacy. Complete blood count (CBC) analysis demonstrated MTME+5-induced hematological abnormalities, including reduced RBCs, hemoglobin, WBCs, and platelets, alongside elevated eosinophils and basophils.

Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS."

Disruption of ER function results in protein misfolding and ER stress, which activate the unfolded protein response (UPR). While the three canonical UPR branches, inositol-requiring enzyme 1 (IRE1), protein kinase RNA-like endoplasmic reticulum kinase (PERK), and activating transcription factor 6 (ATF6), have been extensively studied, the mechanisms that coordinate their activities and ultimately dictate survival or death remain poorly understood. Transmembrane P24 trafficking protein 9 (TMED9), a cargo receptor that cycles between the ER and Golgi, has been implicated in protein quality control under pathological conditions, but its physiological role in ER proteostasis and UPR signaling is unclear. The ER stress response was studied in cellular human models including normal epithelial cells and patient-derived pediatric glioma cultures. To define the regulatory mechanisms dictating TMED9 expression, quantitative Reverse Transcription polymerase chain reaction (qRT-PCR), luciferase reporter assay, and western blotting were employed. To elucidate TMED9 function, loss-of-function approaches, including clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9-mediated knockout and small interfering RNA knockdown were used in combination with RNA-seq and live imaging. Protein stability was tested by pulse-chase experiments, ubiquitination, and degradation analyses. To study the implications of TMED9 activation, we screened curated gene expression datasets from the European Molecular Biology Laboratory- European Bioinformatics Institute (EMBL-EBI) Expression Atlas and employed live-cell imaging-based assays and functional assays (cell viability, apoptosis, migration, and self-renewal). Our study uncovers a physiological role for TMED9 in ER proteostasis and UPR signaling. We show that, under ER stress, TMED9 expression is transcriptionally induced by the IRE1-spliced X-box binding protein 1 (XBP1s) pathway via a conserved unfolded protein response element (UPRE)-like element in its promoter. Removal of TMED9 selectively impairs ATF6 activation without altering IRE1 or PERK signaling, resulting in increased sensitivity to ER stress-induced apoptosis. Mechanistically, we identify TMED9 as a stress-induced stabilizer of ATF6 that prevents its ubiquitin-dependent proteasomal degradation. Functionally, TMED9 regulation is exploited by tumor cells, which sustain IRE1-XBP1s activity to upregulate TMED9, thereby enhancing survival under ER stress conditions. Collectively, our findings establish TMED9 as a critical regulator of ER stress adaptation. TMED9 emerges as a molecular mediator that links IRE1-dependent transcriptional response to ATF6 stabilization, ultimately supporting increased secretory demand under stress conditions and in cancer development."

A comparative study was conducted to analyze the effects of probiotics and IF on SD-induced neuropsychological disturbances and compromised muscle endurance. Forty albino Wistar rats were randomly assigned to four groups. The NSD group was maintained on a standard chow diet for 12\u00a0weeks. The SD group followed an SD regimen for 72\u00a0h per week over 8\u00a0weeks, starting from the fifth week. The SDP group received probiotics at a dose of colony-forming units (CFUs)/100\u00a0g/day for 4\u00a0weeks prior to SD, followed by 8\u00a0weeks of concurrent probiotic administration with SD. The SDIF group underwent an alternate-day fasting regimen for 4\u00a0weeks before SD, followed by 8\u00a0weeks of simultaneous SD combined with IF. Neuropsychological functions and exercise capacity were tested, and then the brains were carefully dissected, sectioned, and processed for hematoxylin and eosin, cresyl violet, and immunohistochemical staining. Inflammatory markers, including interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1), and hippocampal expression of the circadian locomotor output cycles kaput (CLOCK) gene, were significantly elevated in the SD group. Conversely, it showed significant decreases in endurance, exploratory behavior, hippocampal superoxide dismutase (SOD) activity, and fecal short-chain fatty acids (SCFAs). Histological analysis also revealed hippocampal gliosis, apoptosis, CA1 pyramidal cell degeneration, layer disorganization, and upregulation of glial fibrillary acidic protein (GFAP), NF-\u03baB, and cleaved caspase-3. Nevertheless, both probiotics and IF markedly reduced serum MDA, hippocampal CLOCK gene expression, gliosis, and apoptosis and enhanced memory performance. In addition, they significantly increased hippocampal SOD activity and SCFAs.

Mild cognitive impairment (MCI), a transitional stage between normal aging and the onset of dementia, is thought to represent an early phase of this pathological continuum. Studies at the cellular level suggest that the conditions impair the maintenance of established neuronal processes/networks and restrict their capacity for elongation or re-elongation. They may also attenuate the activation and process extension of quiescent neural progenitor or stem-like cells. These early cellular changes precede overt neurodegeneration in neural tissue and are likely to contribute to cognitive decline. They highlight the importance of in vitro models for identifying molecular targets involved in recovery from disease. In this study, we investigated the effects of aggregated A\u03b2 (25-35) on neuronal process elongation and associated intracellular events in the N1E-115 cell line, a widely used model of neuronal differentiation. Addition of aggregated A\u03b2 to cultured N1E-115 cells attenuated process elongation in a concentration-dependent manner. This morphological impairment was accompanied by decreased expression of neuronal differentiation markers. In contrast, at the half-maximal inhibitory concentration for process elongation, long-term cultured cells did not exhibit apparent process retraction or degenerative morphology. This mild but progressive impairment, without extensive cell death, is consistent with the cellular features of early-stage conditions rather than advanced Alzheimer's pathologies. Similar results were observed in primary cortical neurons. A\u03b2 also decreased the level of GTP-bound Ras and phosphorylation of the downstream mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK). Furthermore, treatment with hesperetin, a bioactive flavonoid compound, recovered the A\u03b2-induced inhibition of neuronal process elongation. Hesperetin also restored Ras and MAPK/ERK states, suggesting that its effects are associated, at least in part, with modulation of signaling through Ras and MAPK/ERK. Our findings suggest that hesperetin may serve as a useful molecular probe for modulating early cellular responses associated with Alzheimer's disease-related pathology. This in vitro model might serve as a useful platform for investigating the molecular target candidates involved in recovery from nervous system disorders."

The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made."

Tartrazine was reported to induce hepatotoxicity, however, the effects of tartrazine on nuclear factor erythroid two-related factor two (Nrf2) signaling and endoplasmic reticulum (ER) stress pathways in rat liver have not been investigated. Therefore, this study aimed to investigate the effects of tartrazine on Nrf2 signaling and ER stress pathways in rat liver, to examine the potential therapeutic effects of lycopene, quercetin, and silymarin, and to investigate the mechanisms through which they may mitigate tartrazine-induced liver injury. Rats were allocated into five experimental groups including a normal control group and a tartrazine group that received tartrazine (10 mg/kg) orally for 13 weeks. The lycopene, quercetin, and silymarin groups received tartrazine (10 mg/kg) for 13 weeks and were treated with lycopene (10 mg/kg), quercetin (50 mg/kg), and silymarin (150 mg/kg), respectively, for the last 8 weeks. Tartrazine-induced liver injury was characterized by increased alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase serum levels and histopathological changes in the liver. Furthermore, tartrazine suppressed hepatic Nrf2 signaling and induced ER stress. Hepatic levels of malonaldehyde and caspase-3 were increased, while the levels of superoxide dismutase activity and glutathione and B cell lymphoma-2 were decreased. Moreover, hepatic transforming growth factor-beta one levels and collagen deposition were increased. Treatment with lycopene, quercetin, and silymarin ameliorated the tartrazine-induced changes, upregulated Nrf2 signaling and alleviated ER stress. Our findings suggest that lycopene, quercetin, and silymarin may provide a promising therapeutic approach against tartrazine-induced liver injury."

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."

Our understanding of the mechanisms of irAE in the brain is still evolving, and we recently demonstrated that ICI (blockade of CTLA-4 and PD-1) perturbs hippocampal-dependent memory function by derailing neuro-immune homeostasis and compromising synaptic integrity. However, the spatial patterns and the cell-type-specific molecular mechanisms underlying ICI-related brain dysfunction remain not well-defined. To address this gap, we performed spatial transcriptomic profiling of the hippocampal region using multiplexed error-robust fluorescence in situ hybridization (MERFISH) to map gene expression at single-cell resolution. By integrating spatial single-cell data with bulk RNA-seq, we define the distribution of microglia, astrocytes, synaptic, and neuroinflammatory markers, and determine how ICI reshapes hippocampal cellular composition in a syngeneic murine melanoma model. MERFISH revealed upregulation of microglial, astrocytic, oligodendrocytic, and T cell markers post-ICI treatment, revealing unique pathways driving neuroinflammation, synaptic function, and cellular signaling. Furthermore, immunofluorescence analysis of postmortem brains from patients treated with ICI corroborates our findings of ICI-related immune activation of microglia. Finally, using a conditional deletion model, we show that T cells are indispensable for ICI-driven microglial activation. Altogether, our study provides a high-resolution spatial framework for understanding irAEs in brain function and a T cell-microglia crosstalk axis as a driving mechanism of dysregulated neuro-immune homeostasis during ICI."

Reduced oligodendroglial support has been implicated in ALS progression but remains mechanistically unexplained. Here, using a mutant superoxide dismutase 1 (SOD1-G37R) mouse model of familial ALS, Cre-mediated excision of the mutant SOD1 gene within the oligodendrocyte lineage prior to myelin compaction is shown to slow disease onset, improve motor performance, and prolong survival. In contrast, silencing mutant SOD1 expression within oligodendrocytes after myelin compaction failed to ameliorate disease phenotype. Electron microscopy is used to identify aggregation of mutant SOD1 within paranodal loops and the inner periaxonal tongue of 'myelinic nanochannels', narrow cytosolic compartments for the diffusion of metabolites and motor-driven transport processes. In a second mouse model (SOD1-G93A) of familial, SOD1 mutant-mediated ALS, we show that induction of excessive myelin compaction and myelinic channel collapse (by depletion of CNP from myelin) accelerates disease and diminishes survival. Our data support loss of myelinic channel integrity as a contributor to familial ALS disease initiation and progression, findings likely relevant to neurodegenerative disease involving other aggregation prone proteins that are expressed in myelinating oligodendrocytes. Oligodendrocytes have been implicated in the progression of amyotrophic lateral sclerosis (ALS) but the underlying mechanisms have remained obscure. Here we show in genetic mouse models that the familial ALS causing isoform of a ubiquitously expressed mutant enzyme (SOD1) aggregates in cytosolic channels within myelin that are responsible for delivery of transporters and nutrients necessary to support the axonal compartment. ALS disease progression was accelerated in mice when myelinic channels were collapsed by deleting CNP, a structural protein necessary for myelinic channel maintenance. Disruption of transport through myelinic channels by aggregation of mutant SOD1 may perturb oligodendrocyte support of motor axons and contribute to disease in this form of ALS."

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\nKaryoptosis is a distinct form of cell death regulated by the p38 kinase signaling pathway, involving nuclear degeneration and the cellular expulsion of nuclear material, which stands in contrast to classic apoptotic cascades. While the provided literature extensively links SOD1 mutations to apoptotic pathways in ALS\u2014characterized by protein misfolding, aggregation, and the upregulation of markers such as cleaved caspase-3\u2014it does not explicitly establish a causal association between SOD1 mutations and karyoptosis. The literature confirms that karyoptotic features are identified in patients with ALS/FTD pathology, but SOD1's specific role in the karyoptotic pathway remains uncharacterized in the provided dataset.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nKaryoptosis, a unique cell death mechanism mediated by LaminB1 stability and p38 kinase signaling, is observed in ALS/FTD pathology. SOD1-linked ALS is largely characterized by apoptosis, mitochondrial dysfunction, and excitotoxicity. This analysis assesses whether SOD1 links to karyoptosis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe provided literature establishes that karyoptosis is distinct from apoptosis. \"Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material.\" Regulation of this process is tied to specific kinases: \"We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation.\" Conversely, SOD1-related cell death in ALS is firmly rooted in apoptotic models: \"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).\" Although karyoptosis is a known feature of the broader ALS/FTD spectrum (\"We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology\"), current evidence does not explicitly map SOD1-mediated protein aggregation directly to the p38-LaminB1 karyoptotic pathway.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis operates via nuclear lamina destabilization rather than the classical mitochondrial or extrinsic apoptotic pathways.\n* SOD1 mutations represent a well-characterized genetic cause of ALS, but their signaling is primarily linked to caspase-3 dependent apoptosis.\n* The transition of motor neurons into \"disease-associated motor neurons\" (DMs) in SOD1 models suggests a complex, multiphasic state before cell death occurs.\n* While SOD1-ALS models exhibit increased apoptosis, non-SOD1 models (like FTD-associated proteinopathy) often show a wider range of cell death modalities.\n* The absence of SOD1 in the p38/LaminB1 karyoptosis literature suggests these may be parallel or divergent death programs in neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

It further evaluates the specific association between superoxide dismutase 1 (SOD1) and cell death mechanisms, including its role in apoptosis and its potential link to karyoptotic pathology in amyotrophic lateral sclerosis (ALS).\n\n### [INTRODUCTION & JUSTIFICATION]\nKaryoptosis constitutes a distinct form of cell death regulated by the p38 kinase signaling pathway, which controls the stability of the nuclear lamina protein LaminB1 via direct phosphorylation. In contrast, apoptosis in ALS-linked models often involves oxidative stress-mediated pathways and specific genetic contributions like SOD1 mutations. While SOD1 mutations are well-documented to induce apoptosis, direct empirical evidence linking SOD1 protein specifically to the induction of karyoptosis remains limited or absent in the provided dataset. Both processes appear to represent distinct, though sometimes convergent, pathways of neuronal loss in proteotoxic conditions.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the cellular expulsion of nuclear material, a morphological feature distinct from the chromatin condensation and membrane blebbing typical of classical apoptosis.\n* SOD1 mutations in ALS are traditionally linked to protein misfolding, aggregation, and the subsequent induction of apoptosis.\n* The p38 kinase signaling pathway serves as a regulatory switch for karyoptotic cell death by modulating nuclear lamina structural integrity.\n* Neurodegeneration in ALS/FTD pathology involves complex crosstalk between different regulated cell death forms, including apoptosis, ferroptosis, necroptosis, and karyoptosis.\n* Systemic iron homeostasis and the sequestration of labile iron by ferritin are critical, as their dysregulation triggers ferroptosis, which often overlaps with the stressors inducing apoptosis and karyoptosis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis evaluates the mechanistic differences between apoptosis and karyoptosis within the context of amyotrophic lateral sclerosis (ALS). It investigates the functional role of superoxide dismutase 1 (SOD1) in both regulated cell death pathways to determine if SOD1 pathology extends to karyoptotic neuronal death.\n\n### [INTRODUCTION & JUSTIFICATION]\nApoptosis and karyoptosis represent distinct cellular death modalities. Apoptosis is a well-characterized programmed cell death pathway, whereas karyoptosis is identified as a unique mechanism induced specifically by proteotoxic stress, characterized by nuclear degeneration and the cellular expulsion of nuclear material. Karyoptosis is mechanistically regulated by the p38 kinase signalling pathway, which modulates the stability of LaminB1 via direct phosphorylation. In contrast, apoptosis is frequently triggered by factors such as mitochondrial dysfunction, reactive oxygen species (ROS) accumulation, and dysregulated signaling axes.\n\nEvidence confirms that SOD1 is heavily implicated in ALS pathophysiology, both as a causal mutation and as a protein prone to toxic aggregation. SOD1 mutations are linked to apoptosis through pathways involving the BAX/Bcl-2 ratio, caspase-3 activation, and oxidative stress. Regarding karyoptosis, evidence indicates that karyoptotic features are present in ALS/FTD models where proteotoxic stress is the primary driver. While SOD1 aggregation is a classic hallmark of ALS pathology, its specific involvement as a direct mediator of the p38/LaminB1-driven karyoptotic pathway requires further specific mechanistic studies beyond the general understanding that proteotoxic stress\u2014often exacerbated by mutant proteins\u2014initiates karyoptosis. The literature establishes that karyoptotic features are observable in ALS/FTD contexts, providing a plausible, though not explicitly confirmed, intersection between SOD1-mediated proteotoxicity and karyoptotic death.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the direct expulsion of nuclear material, a morphological hallmark distinct from the apoptotic condensation patterns.\n* The p38 kinase pathway acts as a regulatory node for karyoptosis by modulating LaminB1 stability.\n* SOD1 aggregates in myelinic nanochannels contribute to oligodendrocyte-mediated axonal support loss, distinct from neuronal death.\n* Mutations in SOD1 directly destabilize the local protein structure, promoting $\\beta$-sheet-driven amyloid fibrillation.\n* Oxidative stress serves as a common upstream signal for both apoptosis and other cell death pathways, including PARP1-dependent parthanatos.\n* SARM1 is required for neuronal parthanatos, effectively bridging DNA damage-induced NAD+ loss and cell death.\n* COMMD1 knockdown enhances copper incorporation into SOD1, providing a potential strategy to prevent misfolding-induced apoptosis.\n* Karyoptotic death has been identified in post-mortem tissues of patients with FTD and Alzheimer's disease.\n* Proteasomal degradation of CHK1 in cells with TDP-43 or FUS inclusions links DNA damage accumulation to ALS pathogenesis.\n* Spatial sampling bias in spinal cord segments accounts for significant variability (60%) in reported motor neuron loss in ALS models.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"finalResponse": "To understand how cells die in ALS, think of your cells as having different \"emergency shutdown\" systems. \n\n**Apoptosis** is the body's standard, programmed \"clean\" shutdown. When a cell gets old or damaged\u2014like a cell containing a faulty SOD1 protein\u2014it triggers this self-destruct sequence. It breaks down in a controlled way so it doesn't harm its neighbors. This is very well-documented in ALS research [ID: 42156174].\n\n**Karyoptosis** is a different, more messy type of death. Instead of a controlled shutdown, this process happens when a cell is under severe stress, causing its nucleus (the control center) to essentially break apart and be pushed out of the cell [ID: 42350373]. \n\n**Key Takeaways:**\n* **Different Triggers:** While apoptosis is often linked to the SOD1 protein's failure to fold correctly, karyoptosis is triggered by a specific \"stress switch\" in the cell called the p38 kinase pathway, which causes the cell's structural support (the nuclear lamina) to collapse [ID: 42350373].\n* **The SOD1 Connection:** We know for sure that SOD1-related ALS triggers apoptosis [ID: 42156174]. However, the current scientific research does not yet show if SOD1 is also responsible for the \"karyoptosis\" type of death. They may be two completely separate paths that different motor neurons take toward failing in ALS [ID: 42350373]. \n\nIn simple terms: we know SOD1 triggers the \"standard\" suicide mode for cells, but we aren't yet sure if it triggers the \"nuclear collapse\" mode. They are both ways cells fail, but they seem to be driven by different internal alarm systems.",

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\nKaryoptosis is a distinct form of cell death regulated by the p38 kinase signaling pathway, involving nuclear degeneration and the cellular expulsion of nuclear material, which stands in contrast to classic apoptotic cascades. While the provided literature extensively links SOD1 mutations to apoptotic pathways in ALS\u2014characterized by protein misfolding, aggregation, and the upregulation of markers such as cleaved caspase-3\u2014it does not explicitly establish a causal association between SOD1 mutations and karyoptosis. The literature confirms that karyoptotic features are identified in patients with ALS/FTD pathology, but SOD1's specific role in the karyoptotic pathway remains uncharacterized in the provided dataset.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nKaryoptosis, a unique cell death mechanism mediated by LaminB1 stability and p38 kinase signaling, is observed in ALS/FTD pathology. SOD1-linked ALS is largely characterized by apoptosis, mitochondrial dysfunction, and excitotoxicity. This analysis assesses whether SOD1 links to karyoptosis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe provided literature establishes that karyoptosis is distinct from apoptosis. \"Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material.\" Regulation of this process is tied to specific kinases: \"We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation.\" Conversely, SOD1-related cell death in ALS is firmly rooted in apoptotic models: \"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).\" Although karyoptosis is a known feature of the broader ALS/FTD spectrum (\"We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology\"), current evidence does not explicitly map SOD1-mediated protein aggregation directly to the p38-LaminB1 karyoptotic pathway.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis operates via nuclear lamina destabilization rather than the classical mitochondrial or extrinsic apoptotic pathways.\n* SOD1 mutations represent a well-characterized genetic cause of ALS, but their signaling is primarily linked to caspase-3 dependent apoptosis.\n* The transition of motor neurons into \"disease-associated motor neurons\" (DMs) in SOD1 models suggests a complex, multiphasic state before cell death occurs.\n* While SOD1-ALS models exhibit increased apoptosis, non-SOD1 models (like FTD-associated proteinopathy) often show a wider range of cell death modalities.\n* The absence of SOD1 in the p38/LaminB1 karyoptosis literature suggests these may be parallel or divergent death programs in neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?)\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis assessment synthesizes current evidence on distinct cell death modalities in neurodegeneration, specifically differentiating karyoptosis from apoptosis. It further evaluates the specific association between superoxide dismutase 1 (SOD1) and cell death mechanisms, including its role in apoptosis and its potential link to karyoptotic pathology in amyotrophic lateral sclerosis (ALS).\n\n### [INTRODUCTION & JUSTIFICATION]\nKaryoptosis constitutes a distinct form of cell death regulated by the p38 kinase signaling pathway, which controls the stability of the nuclear lamina protein LaminB1 via direct phosphorylation. In contrast, apoptosis in ALS-linked models often involves oxidative stress-mediated pathways and specific genetic contributions like SOD1 mutations. While SOD1 mutations are well-documented to induce apoptosis, direct empirical evidence linking SOD1 protein specifically to the induction of karyoptosis remains limited or absent in the provided dataset. Both processes appear to represent distinct, though sometimes convergent, pathways of neuronal loss in proteotoxic conditions.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the cellular expulsion of nuclear material, a morphological feature distinct from the chromatin condensation and membrane blebbing typical of classical apoptosis.\n* SOD1 mutations in ALS are traditionally linked to protein misfolding, aggregation, and the subsequent induction of apoptosis.\n* The p38 kinase signaling pathway serves as a regulatory switch for karyoptotic cell death by modulating nuclear lamina structural integrity.\n* Neurodegeneration in ALS/FTD pathology involves complex crosstalk between different regulated cell death forms, including apoptosis, ferroptosis, necroptosis, and karyoptosis.\n* Systemic iron homeostasis and the sequestration of labile iron by ferritin are critical, as their dysregulation triggers ferroptosis, which often overlaps with the stressors inducing apoptosis and karyoptosis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis evaluates the mechanistic differences between apoptosis and karyoptosis within the context of amyotrophic lateral sclerosis (ALS). It investigates the functional role of superoxide dismutase 1 (SOD1) in both regulated cell death pathways to determine if SOD1 pathology extends to karyoptotic neuronal death.\n\n### [INTRODUCTION & JUSTIFICATION]\nApoptosis and karyoptosis represent distinct cellular death modalities. Apoptosis is a well-characterized programmed cell death pathway, whereas karyoptosis is identified as a unique mechanism induced specifically by proteotoxic stress, characterized by nuclear degeneration and the cellular expulsion of nuclear material. Karyoptosis is mechanistically regulated by the p38 kinase signalling pathway, which modulates the stability of LaminB1 via direct phosphorylation. In contrast, apoptosis is frequently triggered by factors such as mitochondrial dysfunction, reactive oxygen species (ROS) accumulation, and dysregulated signaling axes.\n\nEvidence confirms that SOD1 is heavily implicated in ALS pathophysiology, both as a causal mutation and as a protein prone to toxic aggregation. SOD1 mutations are linked to apoptosis through pathways involving the BAX/Bcl-2 ratio, caspase-3 activation, and oxidative stress. Regarding karyoptosis, evidence indicates that karyoptotic features are present in ALS/FTD models where proteotoxic stress is the primary driver. While SOD1 aggregation is a classic hallmark of ALS pathology, its specific involvement as a direct mediator of the p38/LaminB1-driven karyoptotic pathway requires further specific mechanistic studies beyond the general understanding that proteotoxic stress\u2014often exacerbated by mutant proteins\u2014initiates karyoptosis. The literature establishes that karyoptotic features are observable in ALS/FTD contexts, providing a plausible, though not explicitly confirmed, intersection between SOD1-mediated proteotoxicity and karyoptotic death.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the direct expulsion of nuclear material, a morphological hallmark distinct from the apoptotic condensation patterns.\n* The p38 kinase pathway acts as a regulatory node for karyoptosis by modulating LaminB1 stability.\n* SOD1 aggregates in myelinic nanochannels contribute to oligodendrocyte-mediated axonal support loss, distinct from neuronal death.\n* Mutations in SOD1 directly destabilize the local protein structure, promoting $\\beta$-sheet-driven amyloid fibrillation.\n* Oxidative stress serves as a common upstream signal for both apoptosis and other cell death pathways, including PARP1-dependent parthanatos.\n* SARM1 is required for neuronal parthanatos, effectively bridging DNA damage-induced NAD+ loss and cell death.\n* COMMD1 knockdown enhances copper incorporation into SOD1, providing a potential strategy to prevent misfolding-induced apoptosis.\n* Karyoptotic death has been identified in post-mortem tissues of patients with FTD and Alzheimer's disease.\n* Proteasomal degradation of CHK1 in cells with TDP-43 or FUS inclusions links DNA damage accumulation to ALS pathogenesis.\n* Spatial sampling bias in spinal cord segments accounts for significant variability (60%) in reported motor neuron loss in ALS models.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

(RIPK3)-dependent necroptosis.\nExposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted

Begin with a clear Yes or No. Is the synthesis 100% veridical with the validated quotes? Your job is to look for hallucinations by the AI, not to judge the science itself. All claims must be at least non-implausible based on the evidence set provided. Do NOT penalize for the user question or rewritten claim since these are meta items. Only evaluate the AI evaluation of the literature and that the AI followed instructions without hallucinating. List and justify your judgements. Do not use markdown. DO NOT PENALIZE FOR THE USER QUERY WORDING OR REWRITE>>> THAT IS NOT PART OF THE ANSWER ... THAT IS THE QUESTION OR CLAIM EVALUATED.\nAssistant: Yes. The synthesis provided is veridical with the validated quotes and the provided evidence set.\n\nMy evaluation of the AI's performance is as follows:\n\n1. Accuracy of Representation: The synthesis correctly distinguishes between karyoptosis, regulated by the p38/LaminB1 pathway [ID: 42350373], and apoptosis, which the text accurately links to SOD1-mediated protein misfolding, mitochondrial dysfunction, and caspase-3 activation [ID: 42156174].\n\n2. Handling of Missing Associations: The AI correctly identified that while karyoptosis occurs in ALS/FTD pathology [ID: 42350373], the provided literature does not explicitly establish a direct causal link between SOD1 mutations and the p38/LaminB1-mediated karyoptotic pathway. The AI avoided hallucinating a connection where none was explicitly stated in the source text.\n\n3. Adherence to Instructions: The AI followed all constraints, including the requirement for specific source ID citations and the avoidance of internal knowledge outside the provided modules.\n\n4. Non-implausibility: All claims made by the AI regarding the roles of p38, LaminB1, and SOD1 are supported by the provided text. The discussion regarding parallel death programs is a logical synthesis based on the provided evidence rather than a fabrication.\n\n5. Logic and Synthesis: The AI effectively mapped the literature to address the user's specific query without overstepping the bounds of the evidence. No hallucinations regarding scientific mechanisms were detected; the AI consistently cited the source material for every significant claim.\n\n\n=============================\nUser Request: ANSWER IN THIS LANGUAGE --->>> Answer in English only.

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."

Peripheral blood samples were collected from ALS patients and healthy controls (HC) to establish the iPSC-derived motor neurons (MNs). Whole-cell patch-clamp recordings at different culture stages was made using an Axopatch 700B amplifier in combination with pClamp 11 software (Molecular Devices). The frequency of action potentials (APs) was recorded. Additionally, Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) Nick-End Labeling (TUNEL) was used to assess the apoptosis of MNs. ALS patient-derived MNs exhibited significantly higher firing rates compared to HCs at both 4-7 weeks (p = 0.004) and 7-9 weeks (p = 0.009). Further analysis revealed that SOD1-derived MNs showed significantly higher firing frequencies than sALS (p = 0.009) and HCs (p < 0.001) in 4-7 weeks. In 7-9 weeks, it remained significant between SOD1 and HC-derived MNs (p = 0.015), but became insignificant between SOD1 and sALS (p = 0.855).

MNs derived from both patients with mutant SOD1 and sporadic ALS exhibited increased excitability compared to HCs. The increased excitability of MNs derived from ALS patients with mutant SOD1 occurred earlier, and over time, became consistent with the excitability observed in MNs derived from sporadic ALS. The apoptosis rates of MNs showed similar trends. iPSC-derived MNs from both sporadic and mutant ALS may serve as useful cell models for ALS in future studies."

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."

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."

C57BL/6 mice were randomly divided into control (PBS), MNU-induced RP, and MNU+EGCG pretreatment groups. EGCG (50 mg/kg, intraperitoneal) was administered daily for 3 consecutive days prior to a single MNU injection (50 mg/kg). Retinal function was evaluated by scotopic electroretinography (ERG). Retinal structure was assessed using optical coherence tomography (OCT) and hematoxylin-eosin staining, with outer nuclear layer (ONL) thickness measurement. Mechanisms were explored via RNA sequencing, reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) validation of oxidative stress- and inflammation-related genes, and immunohistochemistry for microglial activation, astrocytic gliosis, and apoptosis markers. Compared with the MNU group, EGCG pretreatment significantly preserved scotopic ERG a-wave and b-wave amplitudes (P<0.001). OCT and histological analysis showed that EGCG markedly attenuated MNU-induced thinning of total retina and ONL (P<0.005, P<0.001, respectively). RNA sequencing identified 1147 differentially expressed genes modulated by EGCG, with significant upregulation of antioxidant genes (Nrf2, Sod1, Gpx4, Cat1, Ho-1) and downregulation of pro-inflammatory genes. Immunohistochemistry confirmed that EGCG significantly reduced microglial activation, glial fibrillary acidic protein (GFAP) expression, and cleaved caspase-3-positive cells (P<0.01 to P<0.001). EGCG exerts robust neuroprotective effects in MNU-induced RP through enhancement of antioxidant defenses, suppression of neuroinflammation, and preservation of retinal structure and function. These findings suggest EGCG as a promising candidate for adjuvant antioxidant therapy in RP."

Bax inhibitor 1 (BI1), an endoplasmic reticulum protein downregulated in ALS neuroprotective, represents a therapeutic target, but its metabolic regulatory mechanisms are incompletely understood. Using transcriptomics in skeletal muscle of ALS mice pre- and post-BI1 treatment, we identified BI1-regulated pathways. Structure-based virtual screening of FDA-approved compounds nominated lisinopril as a BI1 activator. Lisinopril upregulated BI1 protein expression, stabilizing mitochondrial membrane potential and protecting against SOD1G93A-induced apoptosis in NSC34 cells. Concurrently, it regulated TGF-\u03b21/mTOR-dependent autophagy, maintained NMJ integrity, and reshaped triglyceride/sphingolipid/glycerophospholipid metabolism to attenuate spinal cord pathology in ALS mice, promoting energy metabolism shift toward glucose oxidation. Additionally, lisinopril inhibited the TGF-\u03b21/Smad2/3 pathway to alleviate muscle fibrosis, downregulate Acp5/FN expression, and reduce type I collagen deposition. In conclusion, this study provides evidence that pharmacological activation of BI1 by lisinopril suppresses TGF-\u03b21, modulates lipid metabolism, and ameliorates ALS pathology, demonstrating promising therapeutic repurposing potential."

Rosmarinic acid (RA), a polyphenolic compound with antioxidant and neuroprotective properties, has not yet been evaluated for mitigating ISO-induced toxicity. In this study, Wistar albino rat pups were exposed to ISO (1.5% in 30% oxygen/air, 3-h) on postnatal days (P)7\u202f+P9\u202f+\u202fP11, and the protective effects of intranasal RA (25\u202fmg/kg) pretreatment (1-h before anesthesia) were investigated for the first time. Control groups received either oxygen alone or RA before oxygen exposure. On P12, hippocampal tissue was examined for detecting acute neuronal apoptosis, oxidative stress, inflammation, and stress-related proteins using histopathology and immunoblotting. Cognitive performance was assessed using Morris Water Maze tests that evaluated spatial learning (P28-P32) and both short- and long-term memory (P33, P60, P90). Repeated ISO exposure impaired learning and memory, increased anxiety-like behaviors, and caused hippocampal damage, along with elevated pro-apoptotic markers (Bax/Bcl-2 ratio, cleaved caspase-3, PARP1 fragments), redox imbalance and inflammation (reduced SOD1; increased GPX1, 4HNE, NF-\u03baB-p65, TNF-\u03b1). ISO also disrupted stress signaling by reducing p-HSF1, Hsp90, and Hsp60 levels, while raising Hsp70 and decreasing 14-3-3 isoforms. RA pretreatment countered these effects by restoring antioxidant and stress-response proteins, reducing inflammation and apoptosis, and maintaining neuronal integrity and cognitive function. No harmful effects were observed in the RA-only group. These findings suggest that intranasal RA pretreatment may be a preventive strategy against anesthesia-related neurotoxicity in pediatric patients."

Thus, novel synthetic quercetin derivatives (QDs) with improved properties and/or drug combinations should be designed and tested. In the present study, anticancer activity of fourteen newly synthesized QDs was investigated using four cellular models of melanoma, namely A375, MM370, G-361, and SH-4 cells. Thioquercetins (thioQ, thioQ(OAc)4, and thioQ(OAc)5), when used at low micromolar range, induced apoptotic cell death in melanoma cells compared to normal cells. Thioquercetins also reduced the population of spheroid-forming cells and suppressed the growth of A375 cells in 3D spheroid models. Thioquercetin-mediated antimelanoma action was potentiated upon heat shock protein 90 (HSP90) inhibition. Co-treatment with the HSP90 inhibitor 17-DMAG and thioquercetins augmented oxidative stress (increased superoxide production, decreased levels of antioxidant proteins SOD1, and PRDX1-2), and impaired the aryl hydrocarbon receptor (AhR)/cytochrome P450 1A1 (CYP1A1) signaling pathway-based detoxification of thioquercetins by the inhibition of AhR translocation to the nucleus and AhR-mediated stimulation of CYP1A1 expression leading to enhanced cytotoxic effects against melanoma cells. The senolytic activity of thioQ(OAc)4 with four acetylated hydroxy groups against cisplatin-induced senescent melanoma cells was also revealed in selected experimental settings. We suggest that the use of novel thioquercetin-based derivatives along with HSP90 inhibitors should be further validated in vivo and considered for the design of more effective antimelanoma strategies in the future."

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."

Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS."

"abstract_text": "ID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies."

The best-established histopathological sequence involves AL-related epithelial apoptosis, phagocytosis of apoptotic bodies by macrophages, and subsequent lipofuscin deposition. Emerging evidence suggests that the gut microbiota (GM) may contribute to this process by converting pharmacologically inactive anthraquinone glycosides into active anthrone metabolites, including rhein anthrone. This narrative review summarizes available MC-specific findings and clearly distinguishes them from mechanistic hypotheses extrapolated from constipation, intestinal barrier, and microbiome literature. We discuss microbial \u03b2-glucosidases and reductases involved in AL biotransformation, reported changes in microbial diversity and SCFA-producing taxa in MC or constipation-associated cohorts, and plausible links with barrier dysfunction, bile-acid metabolism, tryptophan-derived metabolites, and LPS-TLR4 signaling. We therefore present the \"Microbiota-Apoptosis Axis\" as a proposed framework rather than a validated causal pathway. Finally, we review GM-targeted strategies, including probiotics, synbiotics, and fecal microbiota transplantation, while emphasizing that direct clinical evidence in MC remains limited and that cessation of anthraquinone laxatives remains the primary management strategy."

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\nKaryoptosis is a distinct form of cell death regulated by the p38 kinase signaling pathway, involving nuclear degeneration and the cellular expulsion of nuclear material, which stands in contrast to classic apoptotic cascades. While the provided literature extensively links SOD1 mutations to apoptotic pathways in ALS\u2014characterized by protein misfolding, aggregation, and the upregulation of markers such as cleaved caspase-3\u2014it does not explicitly establish a causal association between SOD1 mutations and karyoptosis. The literature confirms that karyoptotic features are identified in patients with ALS/FTD pathology, but SOD1's specific role in the karyoptotic pathway remains uncharacterized in the provided dataset.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nKaryoptosis, a unique cell death mechanism mediated by LaminB1 stability and p38 kinase signaling, is observed in ALS/FTD pathology. SOD1-linked ALS is largely characterized by apoptosis, mitochondrial dysfunction, and excitotoxicity. This analysis assesses whether SOD1 links to karyoptosis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe provided literature establishes that karyoptosis is distinct from apoptosis. \"Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material.\" Regulation of this process is tied to specific kinases: \"We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation.\" Conversely, SOD1-related cell death in ALS is firmly rooted in apoptotic models: \"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).\" Although karyoptosis is a known feature of the broader ALS/FTD spectrum (\"We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology\"), current evidence does not explicitly map SOD1-mediated protein aggregation directly to the p38-LaminB1 karyoptotic pathway.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis operates via nuclear lamina destabilization rather than the classical mitochondrial or extrinsic apoptotic pathways.\n* SOD1 mutations represent a well-characterized genetic cause of ALS, but their signaling is primarily linked to caspase-3 dependent apoptosis.\n* The transition of motor neurons into \"disease-associated motor neurons\" (DMs) in SOD1 models suggests a complex, multiphasic state before cell death occurs.\n* While SOD1-ALS models exhibit increased apoptosis, non-SOD1 models (like FTD-associated proteinopathy) often show a wider range of cell death modalities.\n* The absence of SOD1 in the p38/LaminB1 karyoptosis literature suggests these may be parallel or divergent death programs in neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

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: 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 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), 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 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, 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: 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: 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: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.\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: 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: 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: 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: 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: 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\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: 42177227\nTitle: Nrf2/Bach1-ARE pathway are involved in the ameliorative effects of astaxanthin on D-galactose-induced liver and brain aging and injury.\nAbstract: Astaxanthin (ATX), a natural antioxidant whose benefits in age-related liver and kidney damage remain unclear. We established a D-galactose-induced ageing model in rats and observed the daily behaviour of the rats. Using staining methods to detect ROS, apoptosis and histopathological changes in liver and brain tissue. Determination of antioxidant levels of IL-2, IL-6 and AGES in rats. Assessment of cognitive function using the Morris water maze and ChAT. The mRNA and protein expression levels of Nrf2, Bach1, SOD1, SOD2, HO-1 were determined by real-time PCR and Western blotting. To investigate the role of the Nrf2/Bach1-ARE pathway, we used ML385, a specific inhibitor of the Nrf2 pathway, to treat rats in the inhibitor group. Aging rats showed impaired learning and memory, along with decreased levels of neurotransmitters and antioxidant enzymes. ATX and vitamin E (VE) interventions significantly alleviated these symptoms and activated the Nrf2/Bach1-ARE pathway in liver and brain tissues of aged SD rats. Furthermore, the protective effects of ATX were attenuated by the addition of the Nrf2 inhibitor ML385. ATX reduces oxidative stress and ameliorates liver and brain damage in aged rats via activation of the Nrf2/Bach1-ARE pathway.\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: 42158360\nTitle: Apoptosis-related gene model predicts the prognosis in patients with acute myeloid leukemia.\nAbstract: Acute myeloid leukemia (AML) is a hematological malignancy with a high mortality rate and heterogeneous prognosis. Traditional risk stratification is based on the genetic classification in the 2022 guidelines of the European Leukemia Net. However, the risks of some patients remain unclear, and other prognostic assessment methods are required to improve the risk assessment of these patients. Apoptosis-related genes (ARGs) play critical roles in regulating the survival and drug resistance of AML cells. Therefore, we collected gene expression and clinical data from patients with AML from The Cancer Genome Atlas Acute Myeloid Leukemia (TCGA-LAML) datasets to develop a risk assessment model based on 5 ARGs. Using the least absolute shrinkage and selection operator Cox regression (LASSO-Cox) model, we identified 5 key ARGs (DDIT4, HSP90B1, ENO1, SOD1, and SLC7A11) and constructed a 5-ARG prognostic model. Using this model, we successfully stratified patients in both TCGA-LAML training and independent external validation cohorts, with high-risk patients consistently exhibiting significantly poorer clinical outcomes. In addition, high-risk patients exhibited significant enrichment in pathways related to TP53 dysfunction, mechanistic target of rapamycin complex 1 (mTORC1) signaling activation, and pro-inflammatory responses, which were closely correlated with NPM1c-FLT3 co-mutations. Decitabine, sunitinib, and MK-1775 were identified as potential therapeutic agents. In summary, we established a 5-ARG prognostic model that may facilitate risk stratification and inform therapeutic decision-making in AML.\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: 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: 42096016\nTitle: Impact of melatonin injection in improving ovarian function in aged female pigeon.\nAbstract: Melatonin (MT) has been shown to extend laying period in aged hens, but its effects on aging pigeons remain unclear. 36 pairs of 5-year-old White King pigeons were assigned to either a treatment group receiving 1\u00a0mg of MT for five days or a control group given saline. The effect of MT injection on egg production in pigeon, assess histological characteristics of follicles, antioxidant parameters level and the related gene mRNA levels, steroid hormone levels and the expressions of synthesis genes on the fifth day of the laying interval. MT treatment significantly improved various aspects of egg quality. Moreover, MT increased follicle diameter and granulosa cell layer (GCL) thickness (P\u2009<\u20090.05). MT levels were elevated in plasma and hierarchy follicles yolks (P\u2009<\u20090.05). Progesterone concentrations rose in plasma (P\u2009<\u20090.05), however, estradiol levels decreased in plasma, F1 and F2 yolks (P\u2009<\u20090.05). MT also reduced ROS and MDA levels in plasma and F1 yolk (P\u2009<\u20090.05). Meanwhile, activities of SOD, TAC, and GSH-PX were significantly increased (P\u2009<\u20090.05). MT upregulated SOD1, CAT, and BCL2 mRNA levels in ovary and F1 GCL (P\u2009<\u20090.05). MT significantly increased ovarian expressions of HSD3B1 and CYP11A1, reducing HSD17B1 mRNA levels (P\u2009<\u20090.05); In F1 and F2 GCL, CYP11A1, CYP17A1, and CYP19A1 expressions were all elevated (P\u2009<\u20090.05). These findings suggest that MT promotes hierarchy follicle maturation, reduces apoptosis, thus extending egg-laying period in aging pigeons.\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: 42085907\nTitle: Bmal1 regulates hippocampal oxidative damage in cognitive memory impairment induced by artificial light at night in mice.\nAbstract: Artificial light at night (ALAN) has emerged as a significant public health concern, yet its effects on cognitive impairment remain poorly understood. This study investigated the impact of 28 consecutive days of 5-lx ALAN exposure on hippocampal function in C57BL/6\u00a0J mice. We evaluated locomotor behavior, neuronal morphology, neurogenesis, oxidative stress, and circadian rhythms, revealing that ALAN induces cognitive impairment. ALAN exposure reduced Bmal1 expression, increased reactive oxygen species (ROS) and malondialdehyde accumulation, and disrupted the time-of-day-dependent differences expression of NRF2, SOD1, and GPX1. These alterations suppressed SOD and GPX enzymatic activity, leading to hippocampal oxidative damage. To clarify BMAL1's role, we used adeno-associated virus (AAV) to modulate Bmal1 expression in the hippocampus. ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression. These findings suggest that ALAN can contribute to memory impairment by disrupting hippocampal damage and impairing neurogenesis through its effect on Bmal1. This study identifies potential molecular targets for preventing and treating cognitive impairment and neurodegenerative disorders.\n\nID: 42076688\nTitle: Protective Effects Assessment of Combined Extracts from Periplaneta americana Residues and Cybister chinensis Motschulsky on Feline Renal Cells: In Vitro Evidence Related to Inflammation, Oxidative Stress, and Fibrosis.\nAbstract: With the rising prevalence of feline kidney diseases, effective preventive and therapeutic strategies are urgently needed. This study evaluated the effects of Cybister chinensis extracts (CCME) and Periplaneta americana residue extracts (PAE) on inflammation-associated, oxidative stress-related, and fibrosis-related responses in Crandell-Rees Feline Kidney (CRFK) cells. Using MTT assays, flow cytometry, and qPCR, we assessed cytoprotection in models of lipopolysaccharide (LPS)-, hydrogen peroxide (H2O2)-, and palmitic acid (PA)-induced injury. Preliminary HPLC fingerprint analysis of three batches of a combined extract from Periplaneta americana residues and Cybister chinensis Motschulsky (CPCE) revealed similar chromatographic profiles, indicating good batch-to-batch consistency. Within non-cytotoxic ranges, CPCE increased cell viability and reduced apoptosis in injured CRFK cells. Anti-inflammatory effects were evidenced by significant downregulation of TNF-\u03b1 and IL-6 mRNA. Potential antioxidant-related effects were suggested by decreased expression of oxidative stress-responsive genes SOD1, CAT, and GSTP1. In the PA model, anti-fibrotic potential was supported by reduced TGFB1 expression, accompanied by improvements in inflammatory and oxidative stress markers, and by decreased levels of fibrosis-associated markers \u03b1-SMA, COL I, and HCB III. These findings suggest that CPCE exerts cytoprotective effects in vitro, potentially through modulation of inflammation, oxidative stress, and fibrosis.\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: 41996822\nTitle: Physiological and transcriptomic responses of the gills in Gymnocypris eckloni under acute and chronic hypoxia stress.\nAbstract: With the intensification of global warming and environmental pollution, hypoxia is an unavoidable environmental factor in aquatic ecosystems and has multiple adverse effects on fish. Gymnocypris eckloni, a representative species of the Qinghai-Tibetan Plateau, exhibits excellent adaptability to hypoxic environments, however, little is known about the hypoxic adaptation mechanisms of G. eckloni. Herein, effects of acute hypoxia for 12\u00a0h (H12S) and chronic hypoxia for different durations (H24S, H96S and H168S) on biochemical parameters and transcriptome of G. eckloni gills were investigated. We found that the gills suffered severe oxidative damage and increased anaerobic glycolysis was observed across all groups, and aerobic glycolysis was elevated in H12S. Inflammatory response, apoptosis and translation process were markedly suppressed, and signal transmission and protein synthesis process were strengthened under acute hypoxia stress. Through STEM and WGCNA, we identified several key hub genes (egln, akt, pdk1, foxo1, pfk, gapdh, gk, bax, casp8, il-8 and il-1\u03b2) related to hypoxia from 3608 DEGs, and expression of akt, gk, sdh, gapdh and ldh was significantly upregulated under hypoxia stress, and sod1, cat, bax, casp8 and ccl8 showed an opposite trend. Enrichment analysis revealed that most DEGs were significantly enriched in MAPK signaling pathway, cytokine-cytokine receptor interaction, FoxO signaling pathway, mTOR signaling pathway, glycolysis/gluconeogenesis and apoptosis. The study revealed the differences in the molecular mechanisms of G. eckloni in responding to acute and chronic hypoxia stress, and provided valuable genetic resources for breeding hypoxic-tolerant fish.\n\nID: 41983194\nTitle: Dynamic changes in excitability and viability of sporadic and SOD1-related amyotrophic lateral sclerosis iPSC-derived motor neurons.\nAbstract: To explore the dynamic changes in excitability and viability of induced pluripotent stem cells (iPSC)-derived motor neurons from sporadic amyotrophic lateral sclerosis (ALS) and compare them with SOD1-related ALS patients and healthy control. Peripheral blood samples were collected from ALS patients and healthy controls (HC) to establish the iPSC-derived motor neurons (MNs). Whole-cell patch-clamp recordings at different culture stages was made using an Axopatch 700B amplifier in combination with pClamp 11 software (Molecular Devices). The frequency of action potentials (APs) was recorded. Additionally, Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) Nick-End Labeling (TUNEL) was used to assess the apoptosis of MNs. ALS patient-derived MNs exhibited significantly higher firing rates compared to HCs at both 4-7 weeks (p = 0.004) and 7-9 weeks (p = 0.009). Further analysis revealed that SOD1-derived MNs showed significantly higher firing frequencies than sALS (p = 0.009) and HCs (p < 0.001) in 4-7 weeks. In 7-9 weeks, it remained significant between SOD1 and HC-derived MNs (p = 0.015), but became insignificant between SOD1 and sALS (p = 0.855). The apoptotic rate of sALS (Day 30: 61.37% \u00b1 9.63%; Day 60: 78.41% \u00b1 6.63%) and SOD1 (Day 30: 73.69% \u00b1 8.81%; Day 60: 60.37% \u00b1 11.53%) -derived MNs was significantly higher than those of HCs at both Day 30 (30.72% \u00b1 7.57%) and Day 60 (50.85% \u00b1 19.36%) (p < 0.001). MNs derived from both patients with mutant SOD1 and sporadic ALS exhibited increased excitability compared to HCs. The increased excitability of MNs derived from ALS patients with mutant SOD1 occurred earlier, and over time, became consistent with the excitability observed in MNs derived from sporadic ALS. The apoptosis rates of MNs showed similar trends. iPSC-derived MNs from both sporadic and mutant ALS may serve as useful cell models for ALS in future studies.\n\nID: 41968900\nTitle: Selective Radioprotection by the Fusion Antioxidant Enzyme GS1XR Via an MMP-2/9-Cleavable Cell-Penetrating Switch.\nAbstract: Radiotherapy is central to cancer treatment but radiation-induced oxidative stress also damages normal tissues. To achieve selective radioprotection of normal tissues, we systematically evaluated, in\u00a0vitro and in\u00a0vivo, the antioxidant and radioprotective performance of a previously engineered fusion antioxidant enzyme, GS1XR (GST-SOD1-X-R9). GS1XR efficiently enters normal cells in low matrix metalloproteinases (MMP)-2/9 environments, scavenges radiation-induced reactive oxygen species (ROS), maintains the Nrf2 antioxidant pathway, suppresses apoptosis, and increases clonogenic survival. In contrast, in 3D tumor microenvironments with high MMP-2/9, cleavage of the X peptide removes R9, resulting in a loss of transmembrane capacity and a pronounced reduction in intracellular ROS scavenging. Animal studies further showed that GS1XR significantly alleviates whole-body irradiation-induced hematopoietic injury and, in tumor-bearing models receiving radiotherapy, does not compromise radiotherapy-mediated tumor control. Collectively, GS1XR couples microenvironment-responsive cell entry with enzymatic antioxidation to achieve selective radioprotection while preserving radiotherapy-mediated tumor control.\n\nID: 41967508\nTitle: Toxicological Assessment and Physiological Responses to Dichloro-Octylisothiazolinone and Octylisothiazolinone in Zebrafish Larvae.\nAbstract: The widespread presence of isothiazolinones in aquatic environments has raised concerns regarding their potential effects on nontarget organisms. In this study, the toxicity of 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) and 2-octyl-2H-isothiazol-3-one (OIT), tested individually and in combination, was investigated using the zebrafish (Danio rerio) fish embryo toxicity (FET) test coupled with targeted gene expression analysis. Acute toxicity was evaluated over 96\u2009h after fertilization, and median lethal concentrations (LC\u2085\u2080) were determined. DCOIT exhibited higher intrinsic toxicity (LC\u2085\u2080\u2009=\u20090.015\u2009mg/L) compared to OIT (LC\u2085\u2080\u2009=\u20090.14\u2009mg/L), while the mixture showed increased toxicity (LC\u2085\u2080\u2009=\u20090.006\u2009mg/L). Sublethal developmental effects included pericardial and yolk sac edema following DCOIT exposure and depigmentation in larvae exposed to higher concentrations of OIT. To gain insight into potential molecular responses, the expression of selected genes related to inflammation, oxidative stress, and apoptosis was assessed by qRT-PCR at sublethal concentrations. Exposure to both single compounds and their mixture resulted in the modulation of pro-inflammatory markers (tnf-\u03b1 and il-1\u03b2), antioxidant enzymes (sod-1 and cat), and apoptosis-related genes (casp3 and tp53), with generally stronger responses observed at higher concentrations and under mixture exposure. Overall, the results indicate that early life stages of zebrafish are sensitive to both DCOIT and OIT, and that combined exposure can enhance toxicity and molecular responses. Moreover, early developmental exposure to isothiazolinones is associated with the activation of inflammation-related molecular pathways, highlighting their potential risk for aquatic ecosystems.\n\nID: 41924369\nTitle: Epigallocatechin gallate in N-methyl-N-nitrosourea-induced retinitis pigmentosa mouse model.\nAbstract: To investigate the therapeutic efficacy and underlying mechanisms of epigallocatechin gallate (EGCG), a major green tea catechin with potent antioxidant properties, in an N-methyl-N-nitrosourea (MNU)-induced mouse model of retinitis pigmentosa (RP). C57BL/6 mice were randomly divided into control (PBS), MNU-induced RP, and MNU+EGCG pretreatment groups. EGCG (50 mg/kg, intraperitoneal) was administered daily for 3 consecutive days prior to a single MNU injection (50 mg/kg). Retinal function was evaluated by scotopic electroretinography (ERG). Retinal structure was assessed using optical coherence tomography (OCT) and hematoxylin-eosin staining, with outer nuclear layer (ONL) thickness measurement. Mechanisms were explored via RNA sequencing, reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) validation of oxidative stress- and inflammation-related genes, and immunohistochemistry for microglial activation, astrocytic gliosis, and apoptosis markers. Compared with the MNU group, EGCG pretreatment significantly preserved scotopic ERG a-wave and b-wave amplitudes (P<0.001). OCT and histological analysis showed that EGCG markedly attenuated MNU-induced thinning of total retina and ONL (P<0.005, P<0.001, respectively). RNA sequencing identified 1147 differentially expressed genes modulated by EGCG, with significant upregulation of antioxidant genes (Nrf2, Sod1, Gpx4, Cat1, Ho-1) and downregulation of pro-inflammatory genes. Immunohistochemistry confirmed that EGCG significantly reduced microglial activation, glial fibrillary acidic protein (GFAP) expression, and cleaved caspase-3-positive cells (P<0.01 to P<0.001). EGCG exerts robust neuroprotective effects in MNU-induced RP through enhancement of antioxidant defenses, suppression of neuroinflammation, and preservation of retinal structure and function. These findings suggest EGCG as a promising candidate for adjuvant antioxidant therapy in RP.\n\nID: 41922126\nTitle: The neuroprotective role of eugenol against glyphosate-induced toxicity in rats: Modulation of oxidative stress, inflammation, ER stress and apoptotic signaling pathways.\nAbstract: Glyphosate (GLY) is a widely used herbicide, particularly in agriculture, and its residues in plants and soil can induce toxic effects in various organisms, including humans, with the brain being especially vulnerable. Eugenol (EU), a natural antioxidant found in cloves, has demonstrated protective effects against different toxic substances. This experimental study explored whether eugenol could mitigate neurological damage triggered by glyphosate exposure in rats. A total of forty male Sprague-Dawley rats were allocated into five experimental groups consisting of control, eugenol (100\u202fmg/kg), glyphosate (150\u202fmg/kg), EU50 combined with glyphosate (50\u202fmg/kg + 150\u202fmg/kg), and EU100 combined with glyphosate (100\u202fmg/kg + 150\u202fmg/kg). Animals received the respective treatments by oral gavage for a period of seven days. Motor and anxiety-related behaviors were evaluated using behaviour tests, after which brain tissues were processed for histopathological analysis. Biochemical analyses included ELISA assessment of oxidative stress markers (MDA, SOD1, GSH, and GPx1), RT-PCR analysis of endoplasmic reticulum (ER) stress- and apoptosis-related genes (GRP78, ATF4, CHOP, PI3K/AKT/mTOR, BAX, and Bcl-2), Western blot evaluation of inflammatory and antioxidant signaling pathways (TLR4/NF-\u03baB and Nrf2/HO-1/SIRT1), and immunohistochemical and immunofluorescence analyses of neuroplasticity, circadian rhythm, and autophagy markers (BDNF, BMAL1, CLOCK, Beclin-1, and LC3A/B). GLY exposure significantly increased lipid peroxidation (MDA), ER stress markers (GRP78 and CHOP), pro-inflammatory mediators (TLR4, NF-\u03baB, TNF-\u03b1, and IL-1\u03b2), apoptotic signaling (BAX and caspase-3), and autophagy-related proteins, while suppressing antioxidant pathway components. Glyphosate exposure induced behavioral impairments accompanied by increased oxidative stress, inflammatory activation, endoplasmic reticulum stress, apoptosis, and dysregulated autophagy in cerebral cortex tissue. EU treatment dose-dependently attenuated these molecular and histopathological alterations, restored antioxidant and cellular stress responses, and significantly improved behavioral performance, indicating a protective role against GLY-induced neurotoxicity. Overall, EU may represent a promising therapeutic candidate for mitigating herbicide-induced brain injury.\n\nID: 41917198\nTitle: Lisinopril activates BI1 to reprogram lipid metabolism and restore autophagy in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) involves disrupted lipid metabolism. Bax inhibitor 1 (BI1), an endoplasmic reticulum protein downregulated in ALS neuroprotective, represents a therapeutic target, but its metabolic regulatory mechanisms are incompletely understood. Using transcriptomics in skeletal muscle of ALS mice pre- and post-BI1 treatment, we identified BI1-regulated pathways. Structure-based virtual screening of FDA-approved compounds nominated lisinopril as a BI1 activator. Lisinopril upregulated BI1 protein expression, stabilizing mitochondrial membrane potential and protecting against SOD1G93A-induced apoptosis in NSC34 cells. Concurrently, it regulated TGF-\u03b21/mTOR-dependent autophagy, maintained NMJ integrity, and reshaped triglyceride/sphingolipid/glycerophospholipid metabolism to attenuate spinal cord pathology in ALS mice, promoting energy metabolism shift toward glucose oxidation. Additionally, lisinopril inhibited the TGF-\u03b21/Smad2/3 pathway to alleviate muscle fibrosis, downregulate Acp5/FN expression, and reduce type I collagen deposition. In conclusion, this study provides evidence that pharmacological activation of BI1 by lisinopril suppresses TGF-\u03b21, modulates lipid metabolism, and ameliorates ALS pathology, demonstrating promising therapeutic repurposing potential.\n\nID: 41905503\nTitle: Intranasal rosmarinic acid reduces cognitive and hippocampal damage from repeated neonatal isoflurane exposure by regulating apoptotic/oxidative/inflammatory responses, and heat-shock and 14-3-3 proteins.\nAbstract: Repeated or prolonged exposure to general anesthetics like isoflurane (ISO) during neurodevelopment can lead to long-term neurocognitive and behavioral deficits, particularly because pediatric brains lack adequate antioxidant defenses, and no preventive therapies currently exist. Rosmarinic acid (RA), a polyphenolic compound with antioxidant and neuroprotective properties, has not yet been evaluated for mitigating ISO-induced toxicity. In this study, Wistar albino rat pups were exposed to ISO (1.5% in 30% oxygen/air, 3-h) on postnatal days (P)7\u202f+P9\u202f+\u202fP11, and the protective effects of intranasal RA (25\u202fmg/kg) pretreatment (1-h before anesthesia) were investigated for the first time. Control groups received either oxygen alone or RA before oxygen exposure. On P12, hippocampal tissue was examined for detecting acute neuronal apoptosis, oxidative stress, inflammation, and stress-related proteins using histopathology and immunoblotting. Cognitive performance was assessed using Morris Water Maze tests that evaluated spatial learning (P28-P32) and both short- and long-term memory (P33, P60, P90). Repeated ISO exposure impaired learning and memory, increased anxiety-like behaviors, and caused hippocampal damage, along with elevated pro-apoptotic markers (Bax/Bcl-2 ratio, cleaved caspase-3, PARP1 fragments), redox imbalance and inflammation (reduced SOD1; increased GPX1, 4HNE, NF-\u03baB-p65, TNF-\u03b1). ISO also disrupted stress signaling by reducing p-HSF1, Hsp90, and Hsp60 levels, while raising Hsp70 and decreasing 14-3-3 isoforms. RA pretreatment countered these effects by restoring antioxidant and stress-response proteins, reducing inflammation and apoptosis, and maintaining neuronal integrity and cognitive function. No harmful effects were observed in the RA-only group. These findings suggest that intranasal RA pretreatment may be a preventive strategy against anesthesia-related neurotoxicity in pediatric patients.\n\nID: 41903067\nTitle: HSP90 inhibition potentiates oxidant-based antimelanoma action of novel thioquercetin derivatives by compromising AhR/CYP1A1 pathway.\nAbstract: Quercetin, a plant-derived dietary flavonoid, has multifunctional biological activities, including anticancer action; however, its applications may be restricted due to limited bioavailability. Thus, novel synthetic quercetin derivatives (QDs) with improved properties and/or drug combinations should be designed and tested. In the present study, anticancer activity of fourteen newly synthesized QDs was investigated using four cellular models of melanoma, namely A375, MM370, G-361, and SH-4 cells. Thioquercetins (thioQ, thioQ(OAc)4, and thioQ(OAc)5), when used at low micromolar range, induced apoptotic cell death in melanoma cells compared to normal cells. Thioquercetins also reduced the population of spheroid-forming cells and suppressed the growth of A375 cells in 3D spheroid models. Thioquercetin-mediated antimelanoma action was potentiated upon heat shock protein 90 (HSP90) inhibition. Co-treatment with the HSP90 inhibitor 17-DMAG and thioquercetins augmented oxidative stress (increased superoxide production, decreased levels of antioxidant proteins SOD1, and PRDX1-2), and impaired the aryl hydrocarbon receptor (AhR)/cytochrome P450 1A1 (CYP1A1) signaling pathway-based detoxification of thioquercetins by the inhibition of AhR translocation to the nucleus and AhR-mediated stimulation of CYP1A1 expression leading to enhanced cytotoxic effects against melanoma cells. The senolytic activity of thioQ(OAc)4 with four acetylated hydroxy groups against cisplatin-induced senescent melanoma cells was also revealed in selected experimental settings. We suggest that the use of novel thioquercetin-based derivatives along with HSP90 inhibitors should be further validated in vivo and considered for the design of more effective antimelanoma strategies in the future.\n\nID: 41898728\nTitle: Disturbances in Central Sensitization Are Associated with Disease Severity and Alterations in Gene Expression Measured in the Peripheral Blood Mononuclear Cells of Patients with Rheumatoid Arthritis.\nAbstract: Rheumatoid arthritis (RA) is a chronic autoimmune rheumatic disease of unknown etiolgy, characterized by erosive polyarthritis that leads to joint destruction and systemic inflammatory lesions in internal organs. Pain is a primary symptom of RA and a major contributor to psychological disturbances, which influence patients' subjective evaluation of their condition. These psychological issues may stem from disruptions in central pain regulation mechanisms, such as central sensitization (CS), which can also affect central metabolic processes. The objective was to investigate how the severity of central sensitization, measured by the Central Sensitization Inventory (CSI) questionnaire (Part 1), impacts clinical and neuropsychiatric parameters, as well as the expression of genes related to inflammation, tissue destruction, carbohydrate metabolism, and fatty acid metabolism in peripheral blood mononuclear cells (PBMCs) in patients with RA. Methods involved collecting blood samples from 59 RA patients (mean age 52.0 years). Clinical status was assessed using the DAS28 index and serum levels of CRP, ASPA, and RF. Neuropsychiatric parameters were evaluated through questionnaires measuring CS severity score (CSI), pain intensity (VAS, BPI), neuropathic pain (PainDETECT), anxiety and depression (HADS), fatigue (FSS, FACIT-F), fibromyalgia symptoms (FIRST), and pain catastrophizing. Protein expression in PBMCs was measured by ELISA, while gene expression was analyzed using quantitative real-time RT-PCR. All patients exhibited moderate to high disease activity. Participants were divided into four subgroups according to their CSI scores: subclinical (0-29 points), mild (30-39 points), moderate (40-49 points), and severe/extreme (50-100 points). Higher CSI scores correlated with significant increases in neuropsychiatric symptoms and a notable decrease in vitality. However, clinical parameters showed no significant differences among the subgroups. Gene expression analysis revealed upregulation of genes involved in the pentose phosphate pathway (G6PD), antioxidant defense (SOD1), fatty acid metabolism (FASN, CPT1B), apoptosis (CASP3), and tissue destruction and hypernociception (MMP-9) compared to healthy controls. The pro-inflammatory cytokine IL-1\u03b2 expression was comparable to controls, while TNF\u03b1 expression was elevated only in patients with severe/extreme CS scores. These findings suggest that CS-related disturbances may contribute to increased disease severity in RA, even in patients receiving active antirheumatic treatment. At the cellular level, disease severity appears linked to dysregulated expression of genes governing central metabolic processes, despite low expression of pro-inflammatory cytokine genes.\n\nID: 41890274\nTitle: Excitotoxicity in amyotrophic lateral sclerosis: a key pathogenic mechanism.\nAbstract: Amyotrophic lateral sclerosis is a complex neurodegenerative disease affecting motor neurons, characterized by the involvement of various factors, including oxidative stress, inflammatory processes, glutamate excitotoxicity, mitochondrial dysfunction, protein aggregation, axonal transport abnormalities, and apoptosis. The complexity of amyotrophic lateral sclerosis arises from its multifactorial aetiology involving diverse genetic, protein, metabolic, and cellular alterations. Mutations of different genes, such as SOD1, C9ORF72, TARDBP, and FUS, have been identified as critical contributors to disease pathophysiology through their facilitation of aberrant protein misfolding and aggregation. All these factors disrupt glutamate homeostasis, leading to calcium-mediated neurotoxicity. Under oxidative stress, motor neurons exhibit a diminished capacity to regulate calcium influx, along with impaired functioning of the mitochondria and endoplasmic reticulum, further compromising cellular integrity. Dysregulation of glutamate signalling also triggers astrocytic stress responses, leading to reduced glutamate clearance, thus worsening neuronal damage through excitotoxic mechanisms. These factors contribute to the excessive production of reactive oxygen species, which exacerbates glutamate imbalance and establishes a detrimental cycle of neuronal damage and glial dysfunction, ultimately intensifying excitotoxicity. This review aims to highlight the role of excitotoxicity in motor neuronal degeneration and to explore the molecular mechanisms underlying the pathogenesis of amyotrophic lateral sclerosis. It also examines current therapeutic approaches, including approved treatments and ongoing clinical trials to reduce excitotoxicity, while emphasizing the urgent need for novel, targeted strategies. Given the lack of definitive diagnostic tools and curative therapies, advancing our understanding of the molecular mechanisms driving excitotoxicity and neurodegeneration is, therefore, crucial for the development of more effective, disease-modifying treatments to slow amyotrophic lateral sclerosis progression.\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: 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: 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: 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: 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: 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: 42265995\nTitle: Two Patients With Juvenile-Onset, Rapidly Progressive Amyotrophic Lateral Sclerosis Associated With an SOD1 Variant (p.Asp125Gly) With Incomplete Penetrance.\nAbstract: Amyotrophic lateral sclerosis (ALS) patients are rarely encountered before age 25\u2009years, often associated with genetic variants. SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies.\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: 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: 42186501\nTitle: SOD1 amyotrophic lateral sclerosis associated with Neurosarcoidosis: a case report and review of the literature.\nAbstract: We describe a 37-year-old man with coexisting amyotrophic lateral sclerosis (ALS) caused by a mutation in superoxide dismutase 1 (SOD1) and probable neurosarcoid myeloradiculitis. The concurrence of the two rare conditions posed significant diagnostic and therapeutic challenges. We discuss the diagnostic timeline, therapeutic interventions, outcomes over half a decade of care, and a review of relevant literature.\n\nID: 42183665\nTitle: Expanding the phenotypic spectrum of SOD1\u2011related ALS: upper motor neuron predominance in a p.D91A case.\nAbstract: Mutations in superoxide dismutase 1 SOD1 are the second most common genetic cause of ALS, usually associated with prevalent lower motor neuron phenotypes. We describe a 66-year-old woman with slowly progressive spastic paraparesis, initially diagnosed as primary lateral sclerosis, who carried a heterozygous p.D91A mutation. Clinical and neurophysiological findings indicated predominant upper motor neuron involvement, an unusual presentation for this mutation. This case broadens the SOD1 phenotypic spectrum and highlights the importance of early genetic testing in atypical motor syndromes, given the availability of targeted therapies where diagnostic delay may limit benefit. Amyotrophic lateral sclerosis (ALS) is a disease that affects the nerve cells that control muscle movement. Some of these nerve cells (called \u201clower motor neurons\u201d) send signals directly to muscles, allowing us to move. In some people, ALS is caused by changes in specific genes, including one called SOD1.We describe the case of a 66-year-old woman who gradually developed stiffness and weakness in her legs. Because her symptoms mainly involved stiffness and progressed slowly, she was initially diagnosed with primary lateral sclerosis (PLS), a condition that affects a different group of nerve cells (the \u201cupper motor neurons\u201d) and usually has a slower course. At that time, she underwent genetic testing, but only for genes linked to hereditary spastic paraplegia, a different group of disorders, and no mutations were found.When she was later evaluated in our center, additional tests\u2014including electromyography (a test that studies muscle and nerve function) and detailed neurological examination\u2014suggested ALS. Genetic analysis then identified a specific mutation in the SOD1 gene (called p.D91A).Interestingly, her symptoms were mainly related to upper motor neuron involvement, which is unusual for this mutation.This case shows that SOD1-related ALS can present in unexpected ways, making diagnosis challenging. It also highlights the importance of considering broader genetic testing, even in patients without a family history or with atypical symptoms. Early diagnosis is increasingly important, as new treatments are now available and may be more effective when started sooner.\n\nID: 42178013\nTitle: Design, synthesis, and inhibition of oxidative, amyloidogenic, and cholinergic dysfunction of saxagliptin-derived schiff bases against STZ-induced sporadic AD-like pathology.\nAbstract: Alzheimer's disease (AD) shares significant pathological convergence with diabetes, primarily through insulin resistance. This leads to oxidative stress, neuronal inflammation, plaque formation, cholinergic dysfunction, and impaired neuronal survival. Herein, we report 10 Saxagliptin (SXG, a potent DPP-IV inhibitor)-derived Schiff base derivatives that were virtually designed and screened. Five leads were prioritized using ADMET profiling and molecular docking, then synthesized via Schiff base condensation with selected aryl aldehydes to target AD progression associated with diabetes. Structural integrity, redox activity, and stability were confirmed by comprehensive characterization, including chromatographic and spectroscopic analyses, DFT calculations, and in vitro antioxidant assays. Neuroprotective potential was thus assessed in vivo by inducing AD-like pathology in rats with a single i.p. dose of STZ at 45\u202fmg/kg, thereby reproducing brain insulin resistance, oxidative-nitrosative stress, and cholinergic dysfunction. Significant neurodegeneration in STZ-treated rats was evidenced by behavioral analyses, biochemical markers (AChE, A\u03b242), oxidative stress indices (SOD, CAT, GSH, GPx, MDA, NO, MPO), and hippocampal histology. Treatment with SXG and derivatives at 0.5\u202fmg/kg, orally, resulted in significant restoration of antioxidant defenses, inhibition of lipid peroxidation and NO overproduction, reduction of inflammatory oxidative bursts, and improved cognition in treated groups. Remarkably, derivatives 3c and 3e showed superior free-radical scavenging and greater regulation of redox biomarkers, which were associated with healthy, defined hippocampal cytoarchitecture and reduced neuronal pyknosis and necrosis compared with SXG. Additionally, 3e showed strong therapeutic efficacy by targeting oxidative stress, cholinergic, and amyloidogenic pathways synchronously.\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: 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: 42039583\nTitle: A standardized framework resolves ambiguity in motor neuron loss across neurodegenerative diseases.\nAbstract: Motor neuron (MN) loss is a hallmark of neurodegenerative disorders, yet its assessment remains variable, confounding mechanistic and therapeutic interpretation. To address this, we conducted a systematic review and meta-analysis of spinal muscular atrophy (SMA) mouse studies, revealing 60% variability in reported MN loss, largely attributable to nonspecific spinal cord sampling. Using a whole-segment approach with tissue clearing, MN tracing, and multimodal imaging, we confirmed segment-dependent differences in MN counts. Common MN markers (SMI-32, Nissl) lacked specificity, whereas choline acetyltransferase (ChAT) provided robust labeling in murine and human spinal cords. Deep learning-based whole-mount segmentation enabled unbiased MN quantification and validated manual counts. Integrating analysis with computational modeling established segment sampling as a key driver of variability and revealed degeneration patterns: widespread MN loss in amyotrophic lateral sclerosis (ALS), selective MN loss in severe SMA, and preservation in mild SMA models. These findings establish a framework for reproducible MN quantification.\n\nID: 41996987\nTitle: Decoding RNA splicing pathology: Alternative splicing in amyotrophic lateral sclerosis and its therapeutic potential.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive motor neuron loss, leading to muscle weakness, paralysis, and respiratory failure. Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival.\n\nID: 41957276\nTitle: Elimination of senescent cells fails to attenuate disease progression in an ALS mouse model.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder involving progressive motor neuron degeneration, resulting in muscle weakness and paralysis. Current therapeutic options provide only modest benefit, and the etiology of ALS remains incompletely understood. Emerging evidence implicates cellular senescence in the central nervous system (CNS) of ALS pathogenesis, with senescent astrocytes identified in both animal models and patients. We employed transgenic mice overexpressing the human superoxide dismutase 1 gene with a glycine-to-alanine substitution at codon 93 (hSOD1G93A) as the experimental model. To eliminate senescent cells, mouse-derived natural killer group 2, member D (NKG2D) chimeric antigen receptor T (CAR-T) cells were engineered to target NKG2D ligands (NKG2DLs) + senescent cells. The efficacy of senescent cell clearance was assessed by SA-\u03b2-gal staining on frozen tissue sections and by quantifying the expression of senescence-associated markers (e.g., p16INK4a, p21). Disease progression in mice was evaluated by monitoring changes in body weight, behavioral performance, and motor function. We found that NKG2DLs+ senescent cells accumulate in symptomatic transgenic mice. NKG2D CAR-T cells can selectively eliminate senescent cell populations in symptomatic hSOD1G93A mice. A single infusion effectively reduced senescent cell burden and suppressed Senescence-Associated Secretory Phenotype (SASP) features within central nervous system tissues. However, no significant improvements in motor function or survival were observed. These results indicate that while senescence is a pathogenic feature of ALS, it operates within an integrated disease network. Early senolytic intervention or combinatorial approaches may represent promising future strategies for ALS.\n\nID: 41954708\nTitle: Synergistic Neuroprotection of MFSD2A Overexpression and DHA Supplementation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron loss, with limited effective therapies. Docosahexaenoic acid (DHA) exhibits neuroprotective effects, but its limited transport across the blood-brain barrier (BBB) restricts clinical utility. Major facilitator superfamily domain-containing protein 2A (MFSD2A) is the primary transporter of DHA into the central nervous system, yet its role in ALS remains unclear. This study investigated the therapeutic potential and mechanisms of MFSD2A overexpression combined with DHA supplementation in male SOD1^G93A ALS mice. We found that MFSD2A expression was markedly reduced in ALS mice and correlated with impaired motor function and neuronal damage. DHA supplementation or MFSD2A overexpression partially improved behavioral deficits, while their combination produced synergistic benefits. Histological analyses revealed attenuated neuronal degeneration and reduced muscle fibrosis following combined treatment. Furthermore, MFSD2A physically interacted with the E3 ubiquitin ligase TRIM21, regulating glycolytic metabolism by modulating key enzymes (GLUT1, HK2, LDHA, PDK1) and products (lactate/pyruvate and NADH/NADPH ratio). TRIM21 knockdown reversed MFSD2A-mediated neuroprotection and impaired glycolytic metabolism, indicating its critical role in this pathway. The combined intervention also suppressed systemic inflammation and oxidative stress by decreasing pro-inflammatory cytokines (TNF-\u03b1, IL-6, IL-1\u03b2) and restoring antioxidant enzyme activities (GSH-Px), while reducing lipid peroxidation (MDA). These findings suggest that MFSD2A facilitates DHA's neuroprotective effects by enhancing glycolytic metabolism and mitigating neuroinflammation. This study highlights MFSD2A and DHA as promising therapeutic targets in ALS and provides novel insights into overcoming BBB transport limitations for neurodegenerative disease treatment.\n\nID: 41903869\nTitle: Targeting ME1 rescues redox-metabolic coordination in ALS: A core effector of NRF2-directed therapy.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron loss, muscle weakness, and respiratory failure, with dysregulated energy metabolism and oxidative stress representing core pathological features. Epidemiological studies indicate geographical variations in incidence, and recent multi-omics evidence identifies a hypermetabolic state and mitochondrial dysfunction as key drivers of disease progression. The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2), which regulates antioxidant response and metabolism, represents a promising therapeutic target; however, the exploration of specific activators remains insufficient. This study evaluated the efficacy and mechanism of a novel KEAP1-NRF2 activator, MKL01351, in SOD1 G93A transgenic mice and NSC-34 motor neuron-like ALS models. Behavioral analyses demonstrated that MKL01351 significantly delayed disease onset, improved motor coordination in the rotarod and hanging tests, and extended survival. The compound alleviated oxidative stress by reducing malondialdehyde (MDA) levels and restoring the reduced glutathione/oxidized glutathione (GSH/GSSG) ratio, while also ameliorating the energy deficit by modulating glycolytic and mitochondrial functions, as confirmed by Seahorse analysis. Mechanistic investigations revealed that MKL01351 activated the NRF2 pathway, upregulating downstream targets such as NQO1 and HO-1, and specifically enhanced the expression of malic enzyme 1 (ME1). Loss-of-function experiments confirmed that ME1 knockdown abolished the protective effects, indicating that the NRF2-ME1 axis is a central hub for the synergistic regulation of metabolic and oxidative homeostasis. In conclusion, MKL01351 concurrently ameliorates oxidative stress and metabolic dysregulation via the NRF2-ME1 signaling pathway, offering a novel neuroprotective strategy for ALS treatment.\n\nID: 41890591\nTitle: Axonal transport impairment as an upstream mechanism in amyotrophic lateral sclerosis pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive loss of upper and lower motor neurons. Despite marked genetic and pathological heterogeneity, a unifying pathogenic framework remains lacking. We propose that axonal transport impairment represents an early and convergent but genotype-modulated upstream vulnerability in ALS, contributing to distal synaptic failure, bioenergetic stress, protein aggregation, neuroinflammation, and neuronal death. Across many ALS models, including SOD1, TARDBP (TDP-43), FUS, and C9orf72, transport deficits are frequently detectable in presymptomatic stages, often preceding overt motor neuron loss or clinical manifestation, although temporal ordering varies by molecular subtype. Human data from induced pluripotent stem cell-derived motor neurons and neuroimaging in mutation carriers further support early transport dysfunction in both familial and sporadic ALS. We synthesize genetic, cellular, and systems-level evidence demonstrating that diverse ALS-associated mutations converge on intracellular trafficking machinery through distinct but interacting mechanisms, disrupting long-range cargo delivery and clearance in motor neurons. This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation. This model generates testable predictions regarding presymptomatic transport biomarkers and the timing of therapeutic intervention. We discuss implications for biomarker development and therapeutic strategy, proposing restoration of axonal transport as a central component of rational multimodal disease modification in ALS.\n\nID: 41850233\nTitle: Identification of tofersen PD-response biomarkers in VALOR clinical trial CSF via multiplexed quantitative proteomics.\nAbstract: Tofersen, the first approved genetically targeted therapy for amyotrophic lateral sclerosis (ALS), demonstrates significant lowering of plasma neurofilament in adults carrying mutations in the superoxide dismutase 1 (SOD1) gene; however, additional biomarkers of treatment response in ALS are lacking. Here, we analyze longitudinally collected cerebrospinal fluid (CSF) samples from the phase 3 VALOR clinical trial to identify candidate tofersen treatment-response biomarkers in SOD1-ALS via quantitative proteomics. We observe significant modulation from baseline abundance for 56 proteins in tofersen-treated participants relative to placebo, including CSF GPNMB, which is significantly and continuously elevated across all post-baseline timepoints. We orthogonally confirm this observation by GPNMB immunoassay in independent tofersen-treated cohorts. Taken together, these data identify pharmacodynamic-response biomarkers of tofersen treatment that can be measured as early as 4 weeks post-treatment in SOD1-ALS patients and demonstrate the utility of leveraging unbiased proteomic screening integrated with targeted validation methods to identify pharmacodynamic-response biomarkers in clinical trial patient samples.\n\nID: 41839426\nTitle: High-throughput screening of ALS patient iPSC-derived spinal motor neurons identifies novel compounds that increase neurofilament light chain expression.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease primarily affecting motor neurons both in the spinal cord and brain. The cardinal pathology of ALS is motor neuron-selective inclusion of proteins such as TDP43, SOD1, C9orf72-derived dipeptide repeats, or FUS due to the mutations in the genes encoding them. Both familial and sporadic forms of ALS also show neurofilament (NF) aggregates, attributed to an imbalance in subunit expression, particularly a decrease in neurofilament light chain (NF-L) levels. Current FDA-approved treatments extend survival for only a few months, highlighting the urgent need for new therapies. In this study, we developed a cell-based reporter system for high-throughput screening by engineering induced pluripotent stem cells (iPSCs) derived from ALS patients and differentiating them into spinal motor neurons. We screened over 6000 compounds using these reporter iPSC-derived motor neurons and identified a novel compound that increases NF-L expression by >50 %. However, this novel compound also inhibits TGF-\u03b2 signaling, prompting us to optimize its activity through a hit-to-lead chemistry analysis. In our subsequent investigations, we identified an additional compound that does not affect TGF-\u03b2 signaling and outperforms the original compound in both in vitro and in vivo drug metabolism and pharmacokinetics assays. Our study highlights the utility of iPSC-derived neurons in disease modeling and illustrates how they can be employed to discover new compounds for therapeutic development through extensive screening in disease-relevant settings.\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: 41785390\nTitle: Gadolinium enhancement of the cauda equina in a case of familial ALS with p.S135G SOD1 mutation.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder characterized by motor neuron degeneration. Gadolinium enhancement of the cauda equina is typically associated with inflammatory diseases. We report a case of familial ALS with a Cu/Zn superoxide dismutase (SOD1) gene mutation showing marked gadolinium enhancement of the lumbar nerve roots. To date, only a few cases of ALS with gadolinium enhancement of the nerve roots have been reported. To our knowledge, this is the first reported case of ALS with an p.S135G SOD1 mutation exhibiting gadolinium enhancement in the cauda equina.\n\nID: 41776544\nTitle: Intranasal administration of human mesenchymal stromal cell-derived small extracellular vesicles delays disease progression in the SOD1(G93A) mouse model.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron loss, with no established disease-modifying therapy. Mesenchymal stem/stromal cells (MSCs) have been reported to exert neuroprotective effects in models of injury and disease, acting primarily through release of small extracellular vesicles (sEVs). MSC-derived sEVs (MSC-sEVs) have therefore attracted attention as a potential cell-free therapeutic approach for treating neurological conditions such as ALS. Because MSC-sEVs can cross both the nasal epithelial barrier and blood-brain barrier to reach the central nervous system (CNS), intranasal administration represents an attractive approach for repeated delivery of MSC-sEVs for long-term administration. In this study, we administered bone marrow-derived MSC-sEVs or vehicle intranasally to a SOD1(G93A) transgenic mouse model of ALS; the large majority of the sEVs had surface markers for exosomes. Dosing was for three consecutive days per week beginning one day after onset of neurological symptoms and continuing until a moribund state. Neurological score and body weight were recorded daily. Although total survival time and post-onset survival duration were not significantly prolonged by MSC-sEV treatment, MSC-sEV treatment significantly delayed progression from a mild symptom phase (NeuroScore 1) to more severe symptoms (NeuroScore 2) compared with vehicle-treated controls and showed a trend toward slower weight loss. These findings indicate that intranasal administration of MSC-sEVs can delay functional deterioration and prolong the mild impairment stage in an ALS mouse model. If translatable to human patients, such preservation of neurological function could represent a clinically meaningful outcome.\n\nID: 41766077\nTitle: Respiratory Onset Amyotrophic Lateral Sclerosis in a Patient With C9orf72 Expansion.\nAbstract: Respiratory-onset amyotrophic lateral sclerosis (ALS) is uncommon, accounting for less than 5% of all patients with ALS. Familial ALS is also uncommon, with the most common variant being related to a C9orf72 hexanucleotide repeat expansion. Respiratory-onset ALS in familial ALS is rare, with few cases discussed in the literature related to ERBB4, SOD1, and FUS variants. Here we present a case of respiratory-onset ALS related to a C9orf72 repeat expansion, expanding the spectrum of associated phenotypes associated with C9orf72 expansions and highlighting the importance of genetic testing in patients living with ALS.\n\nID: 41764146\nTitle: Neuroinflammation and Oxidative Stress in SOD1 Animal Models of ALS: A Meta-analysis Study of Their Effects on Disease Onset and Progression.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a multifactorial neurodegenerative disorder characterized by progressive motor neuron degeneration. Among the key mechanisms implicated in ALS pathogenesis, neuroinflammation and oxidative stress have emerged as prominent contributors to disease progression. This systematic review with meta-analysis involved 344 preclinical studies conducted on SOD1 animal models of ALS, to quantitatively evaluate the effects of treatments targeting neuroinflammation and oxidative stress on functional outcomes such as disease onset, survival, motor neuron degeneration, and locomotion. Data extraction and validation were performed using a combination of a large language model and human review. Results show that while most interventions led to reduced astrogliosis, M1 microgliosis, and oxidative stress, and increased M2 microgliosis, these effects were more strongly associated with improved survival and motor outcomes than with delayed disease onset. The analysis also revealed that treatment timing significantly influences outcomes, with interventions initiated during the late pre-onset window showing the highest efficacy. Furthermore, sex differences were noted, with male mice displaying better outcomes in progression metrics but worse in the age at onset. Overall, this meta-analysis indicates that inflammation and oxidative stress are important contributors to ALS progression in SOD1 animal models, identifies potentially critical therapeutic windows, and supports the consideration of sex-balanced and stage-specific treatment strategies at the preclinical level.\n\nID: 41723979\nTitle: Allicin improves motor neuron survival in amyotrophic lateral sclerosis by reducing neuroinflammation and modulating gut microbiota.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of motor neurons (MNs). Allicin, a defensive molecule in garlic with anti-inflammatory and gut microbiota-modulating properties, has shown therapeutic potential in animal models of various diseases including Alzheimer's disease (AD). However, its possible therapeutic role in ALS remains unclear. The purpose of this study is to investigate the therapeutic effect of allicin in ALS transgenic SOD1G93A mice. Starting at 60 days of age, SOD1G93A mice received oral gavage of allicin (10\u202fmg/kg) on alternate days, while the control group received an equal volume of normal saline (NS) on the same schedule. Twelve mice per group were used for monitoring disease onset and survival. Nissl staining and choline acetyltransferase (ChAT) immunofluorescence were used to quantify MNs in the anterior horn. Microglial activation was analyzed by immunofluorescence staining for Iba1, ARG1, and CD86. The mRNA expression levels of IL-10, TGF-\u03b2, IL-1\u03b2, and TNF-\u03b1 were examined using qPCR. Additionally, fecal samples were collected for 16S rDNA sequencing to evaluate changes in gut microbiota composition. We observed that allicin treatment failed to prolong the onset time and survival period of SOD1G93A mice, but it extended the disease duration. Nissl staining analysis revealed that allicin treatment delayed the loss of spinal MNs, a finding corroborated by ChAT immunofluorescence. Furthermore, allicin treatment significantly reduced neuroinflammation and improved gut microbiota. Taken together, although allicin may prolong disease duration in ALS, it did not improve overall survival or delay disease onset. Therefore, its potential disease-modifying effects require further validation.\n\nID: 41710977\nTitle: BTK inhibition suppresses neuroinflammation and neurodegeneration in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis(ALS) is a devastating neurodegenerative disorder with limited therapeutic interventions. Neuroinflammation represents a central pathogenic mechanism in ALS, yet the upstream molecular regulators that integrate multiple inflammatory cascades remain poorly understood. Here, we investigated whether Bruton's tyrosine kinase (BTK), which integrates DNA-sensing and Toll-like receptor signals upstream of the cGAS-STING-NF-\u03baB cascade, serves as a key regulatory node in ALS pathogenesis. Public RNA-seq datasets of motor neurons and post-mortem tissues from ALS patients were utilized to identify BTK expression patterns. SOD1-mutant human induced pluripotent stem cells (hiPSC) were differentiated into motor neurons (hiPSC-MNs) and microglia (hiPSC-MGs). NF-\u03baB dysregulation was profiled by scRNA-seq (hiPSC-MGs) and bulk RNA-seq (hiPSC-MNs). DNA damage (\u03b3H2AX), inflammatory signalling (western blot/ELISA) and phagocytosis (pH-rodo uptake) were quantified, and MG-conditioned medium was tested for MN toxicity. Monocultures and MN-MG co-cultures received zanubrutinib (3 \u00b5M, 12 h). SOD1-G93A mice were administered zanubrutinib (30 mg/kg, daily) from 2.5 months; motor performance, survival, spinal histology and PI3K-AKT-mTOR activity were assessed after 2 months of treatment. ALS spinal cord and cortex tissues of patients, as well as SOD1-mutant hiPSC-MGs and hiPSC-MNs, demonstrated elevated BTK phosphorylation with increased p-STING, p-TBK1, and nuclear NF-\u03baB accumulation. ALS hiPSC-MGs exhibited inflammatory activation, NLRP3 induction, and impaired phagocytosis, while ALS hiPSC-MNs showed DNA damage and caspase-3-mediated apoptosis. Conditioned medium from inflammatory microglia amplified neuronal STING-NF-\u03baB activity and apoptosis, demonstrating non-cell-autonomous toxicity. The STING inhibitor H-151 reduced neuronal p-STING/p-TBK1/NF-\u03baB and apoptosis, confirming pathway causality. Pharmacological BTK inhibition reduced DNA damage in ALS hiPSC-MNs by 61.4% (p<0.05), restored phagocytosis in ALS hiPSC-MGs to 87.2% of control levels (p<0.01), and prevented neuronal apoptosis induced by microglial conditioned medium. In SOD1-G93A mice, BTK blockade extended median survival from 158 to 173 days (p<0.01, log-rank test), improved motor function, and attenuated neuroinflammation while moderately rebalancing PI3K-AKT-mTOR signaling without impairing autophagy-lysosome dynamics. We identify BTK as a critical upstream regulator of the dysregulated cGAS-STING-NF-\u03baB signalling axis characteristic of ALS pathogenesis. BTK orchestrates both cell-autonomous dysfunction in motor neurons and non-cell-autonomous toxicity through microglial activation, representing a convergent regulatory node that integrates multiple pathogenic pathways. These mechanistic insights provide a molecular framework for understanding ALS neuroinflammation and establish a rational basis for BTK-targeted therapeutic intervention in neurodegeneration.\n\nID: 41702846\nTitle: Efficient induction of motor neuron disease in transgenic G93A SOD1 mice by prion-like seeding.\nAbstract: Mutations in superoxide dismutase 1 (SOD1) cause paralysis in familial amyotrophic lateral sclerosis and promote its misfolding into neurotoxic aggregates. Previous studies have shown that mice expressing the ALS-causing G85R variant of SOD1 develop paralysis much faster after intraspinal injection of spinal homogenates from paralysed G85R SOD1 mice. These findings, and other studies in cell models, established the prionoid templating properties of misfolded mutant SOD1. Previously, however, we noted that the widely used Gur1-G93A SOD1 mice, which express at high levels and develop paralysis by 6\u2009months of age, were resistant to seeding by homogenates from paralysed G93A mice. A line of G93A mice that expresses at very low levels (VLE-G93A) was responsive to seeding but at low efficiency. The poor susceptibility of G93A-SOD1 mice to seeding was not what we expected if prion-like propagation is essential to SOD1 ALS pathogenesis. In our prior studies, seeding homogenates from paralysed G93A-SOD1 mice were injected into the spine of newborn mice, leading us to question whether older G93A SOD1 mice might be more susceptible to seeding. Here, we establish that adult VLE G93A SOD1 mice (up to 12\u2009months of age) injected intrathecally with seeding homogenates containing misfolded G93A or G85R SOD1 developed accelerated motor neuron disease efficiently. Thus, we demonstrate that both the route and age of inoculation can influence the efficiency of SOD1 seeding to induce motor neuron disease in VLE G93A-SOD1 mice. These data, together with our earlier reports, suggest that prion-like templating contributes to disease progression in SOD1-ALS.\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: 41670738\nTitle: Treating SOD1-ALS with tofersen results in nonprogressive chronic ALS-a case series from Iceland.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder. We describe four patients with hereditary ALS caused by the p.Gly94Ser SOD1 mutation who were treated monthly with the intrathecal antisense oligonucleotide tofersen in a clinical setting at Landspitali University Hospital of Iceland. After initiating treatment 15-26\u00a0months ago, no significant clinical deterioration was observed, and three patients showed signs of clinical improvement, with some recovery of motor function. All four patients currently present with chronic nonprogressive ALS, a phenotype not previously observed or documented. Concomitantly, the concentration of neurofilament light chain (Nf-L) in the cerebrospinal fluid decreased to the normal range. This clinical benefit and decrease in Nf-L levels were detected regardless of the patient's initial ALSFRS-R score. No serious adverse events were observed. Notably, we observed a clinically meaningful effect in two patients who had been ill for several years before treatment was instituted, raising questions about who should receive treatment and the biology of paresis and motor neuron cell loss in patients with ALS. Although only a minority of ALS patients carry a SOD1 mutation, the advent of this new precision medicine has profound implications for ALS management.\n\nID: 41664997\nTitle: N-Truncated Superoxide Dismutase-1 in Cerebrospinal Fluid Is Folded and Active.\nAbstract: Mutations in the antioxidant enzyme superoxide dismutase-1 (SOD1) are a well-established cause of amyotrophic lateral sclerosis (ALS). The mutations promote SOD1 misfolding, resulting in protein aggregation and motor neuron degeneration. SOD1 is normally a structurally stable enzyme, and the mechanisms underlying SOD1 misfolding remain poorly understood. Approximately one third of SOD1 in cerebrospinal fluid (CSF) exhibits an N-terminal truncation, the biological significance of which remains unclear. This is remarkable given the dramatic effects ALS-linked C-terminal truncations have on the enzyme. In this study, we identified the truncation site and investigated its impact on SOD1 stability and enzymatic activity. Edman degradation revealed the cleavage site between Asn-26 and Gly-27, generating a 26-residue peptide that was confirmed by mass spectrometry. We analyzed postmortem tissues from different parts of the central nervous system (CNS), including the choroid plexus, and found only trace amounts of N-terminally truncated SOD1. Biochemical characterization of the SOD1 in CSF was done by size exclusion chromatography, ion exchange chromatography, and mass spectrometry. Our findings demonstrate that SOD1 in CSF retains full enzymatic activity, that the N-terminally truncated variant is mainly present in heterodimers with native SOD1 subunits, and that the dimer remains folded and active, with both fragments of the truncated SOD1 fixed after proteolysis. Truncated SOD1 was absent in human plasma. In mice, only transgenically expressed human SOD1 underwent truncation in CSF, whereas endogenous murine SOD1 remained intact. Lastly, the N-terminal truncation does not induce misfolding, unlike the destabilizing effects observed with C-terminal truncations. The location where the truncation takes place and the underlying mechanism could not be identified. Whether the N-truncated SOD1 variant contributes to ALS pathogenesis remains to be determined.\n\nID: 41651252\nTitle: Novel extracellular vesicle release pathway facilitated by toxic superoxide dismutase 1 oligomers.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that results in paralysis and death within three to five years. Mutations in over forty different proteins have been linked to ALS, raising debate over whether ALS is a single disease or multiple disorders with similar symptoms. Mutations in Cu,Zn superoxide dismutase 1 (SOD1) are found in only 2-3% of ALS cases, yet misfolded SOD1 appears in both sporadic (sALS) and familial (fALS) patients. Furthermore, mutations in TDP-43 or FUS increase levels of misfolded SOD1 on extracellular vesicles (EVs). Small EVs isolated from ALS patient samples have been shown to cause death of wild-type motor neurons and myotubes, supporting the theory that EVs play a role in spreading disease. We hypothesize that the previously identified toxic trimeric SOD1 spreads via EVs in ALS and influences the distribution of other ALS-related proteins, suggesting a common mechanism. To test this, we isolate EVs from motor neuron-like cells expressing mutations that stabilize trimers. We then perform a sandwich enzyme-linked immunosorbent assay (ELISA) using a CD9 capture antibody to measure whether misfolded SOD1 and 17 other ALS-related proteins increase or decrease on EVs with trimer stabilization. We identify which EV release pathway is affected by trimeric SOD1 using endocytosis and exocytosis inhibitors and analyze altered protein interaction pathways through co-immunoprecipitation and mass spectrometry proteomics. Our results show that VAPB, VCP, and Stathmin-2 increase on EVs when trimers are stabilized. The common pathway linking these ALS-associated proteins and SOD1 appears to involve multiple mechanisms, including the Caveolae endocytosis pathway, pointing to a novel hybrid EV release pathway in ALS. Overall, our findings show that trimeric SOD1 influences EV cargo and spread in ALS.\n\nID: 41649802\nTitle: Naringin Mitigates Synergistic Brain Aging Model Induced by D-Galactose and Gamma Radiation via Targeting Oxidative Stress, Inflammation and Senescence.\nAbstract: Brain aging is a multifactorial process driven by oxidative stress, chronic inflammation, and cellular senescence, culminating in neurodegeneration and cognitive decline. In this study, we established a robust aging model by synergistically combining d-galactose and acute gamma-irradiation (6\u2009Gy), intensified senescence-associated phenotypes in rat brain tissue. Rats were divided into four groups: Group I: negative control; group II (naringin-treated): rats were given naringin (50\u2009mg/kg; p.o.) for 1 week; group III (Rad+ D-galactose): rats were exposed to whole-body gamma radiation (6\u2009Gy) and then received D-galactose (300\u2009mg/kg b. wt. i.p.) for 7 days; group IV (Rad+ D-galactose+ naringin): as in group III, then naringin (50\u2009mg/kg b. wt. p.o.) for 1 week. This model exhibited elevated levels in IL-6, TNF-\u03b1, p16INK4A, p21CIP1 and retinoblastoma protein (Rb) levels, as well as upregulated NF-\u03baBp65 protein expression in brain tissue. Remarkably, naringin supplementation reversed the pathological signatures, restoring antioxidant balance, suppressing inflammatory mediators, and modulating apoptotic pathways. Histological hallmarks such as gliosis, neurophagia, and pyknosis, as well as immunohistological staining of caspase-3 and p53 expression, confirmed the aforementioned consequences. Collectively, these findings highlight naringin's therapeutic potential in mitigating brain aging by targeting oxidative stress, inflammation, and apoptosis. This study offers a robust experimental framework for investigating senescence and supports naringin as a promising candidate for intervention in age-related neurodegenerative disorders.\n\nID: 41621017\nTitle: Genetic commonalities between rare subtypes of ALS and CMT: insights into molecular mechanisms of neurodegeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) and Charcot-Marie-Tooth disease (CMT) are two distinct neurodegenerative disorders. While ALS is characterised by rapidly progressive motor neuron degeneration, leading to severe complications and death, CMT as a peripheral neuropathy is less severe, and patients have a longer life span, although with a compromised quality of life. Despite their clinical differences, current knowledge suggests that familial ALS (fALS) and CMT may share common genetic and molecular mechanisms. We aimed to identify shared genes mutations and molecular pathways between fALS and CMT through a literature and database search. Thirteen genes were identified, involved in distinct cellular processes: axonal transport (DYNC1H1, KIF5A, SPG11, DCTN1), protein homeostasis (NEFH, VCP, SOD1), RNA metabolism (GARS, SETX), cellular stress response (HSPB1, FIG4), and mitochondrial function (MFN2, CHCHD10). While these linkages to the two diseases are rare for each gene, understanding possible mechanistic commonalities at the molecular level can initiate new research directions, help in identifying additional common genes between neurodegenerative disorders, and improve diagnostics.\n\nID: 41616251\nTitle: A gut-activated NHR-86-CYP pathway mediates the neuroprotective effects of Enterococcus faecium probiotics in a nematode model of amyotrophic lateral sclerosis.\nAbstract: Neurodegenerative diseases are often associated with oxidative stress, and while probiotics may influence neuronal health, the underlying mechanisms remain poorly understood. Using the sod-1 A4VM amyotrophic lateral sclerosis (ALS) model in Caenorhabditis elegans, we investigated the protective effects of the probiotic Enterococcus faecium against oxidative stress-induced neurodegeneration. Animals fed E. faecium showed reduced motor neuron degeneration under oxidative stress compared to those maintained on a standard Escherichia coli diet. Transcriptome analysis revealed a significant enrichment of oxidoreductase genes, including cytochrome P450 (cyp) genes. RNAi-mediated knockdown of cyp genes impaired E. faecium-mediated neuroprotection, and this loss correlated with increased reactive oxygen species (ROS) levels. We identified the conserved nuclear hormone receptor NHR-86 as a key regulator of cyp gene expression and neuroprotection. Loss of nhr-86 abolished the probiotic's protective benefits, while transgenic expression of nhr-86 restored cyp induction and neuronal resilience. Importantly, intestinal expression of NHR-86 was sufficient to restore CYP induction and neuronal resilience, whereas neuronal knockdown had no effect, indicating that gut NHR-86 activity is essential for this protective pathway. These findings reveal a previously uncharacterized NHR-CYP regulatory axis activated by an intestinal probiotic, highlighting a mechanistic link between microbial signals and host neuroprotection.\n\nID: 41601590\nTitle: Apolipoprotein A1 reduces blood-spinal cord barrier leakage, improves astrocytic coverage, and enhances motor neuron survival to restore the neurovascular unit in ALS mice.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive, age-related motor neuron degenerative disease with multiple causal factors. Dyslipidemia has been identified as an important pathological element. Impaired lipid protein metabolism manifests in ALS patients and in an ALS mouse model. Apolipoprotein components are the primary regulators of plasma lipid metabolism. Apolipoprotein A1 (ApoA1), a high-density lipoprotein, acts as an antioxidant and reduces inflammation, preventing blood vessel injury. However, the effects of ApoA1 upon the ALS-damaged endothelium in the CNS are unknown. The objective of the study was to determine the effect(s) of injecting ApoA1 into G93A SOD1 mice at the early symptomatic stage. A single dose of ApoA1 or media was systemically administered into 13-week-old G93A SOD1 male and female mice. Body weight and tests of motor function were evaluated weekly for 4\u202fweeks post-injection. Permeability of spinal cord capillaries was determined by Evans blue (EB) fluorescent dye injected into mice at 17\u202fweeks of age. Immunohistochemical analyses determined the statuses of glial cells and ApoA1 distributions in ALS mice cervical/lumbar spinal cords. Motor neurons in cervical/lumbar spinal cord ventral horns of ApoA1-treated and media-injected ALS mice were stained with cresyl violet for histological analyses. ApoA1 injected into G93A SOD1 mice at the early symptomatic stage significantly benefited both male and female animals by (1) delaying behavioral disease progression; (2) reducing EB capillary leakage into spinal cord parenchyma; (3) lessening astrogliosis and microgliosis; (4) protein incorporation into capillary endothelium and motor neurons; and (5) improving survival of motor neurons in the spinal cord. Our novel data showed that systemically administered ApoA1 benefited ALS mice of both sexes, likely by beneficial effects on damaged microvessels, possibly engendering restoration of neurovascular unit integrity. Moreover, an anti-inflammatory ApoA1 effect was demonstrated by the reduction of glial cell activation, potentially mitigating vascular injury. The results of our preclinical study suggest that ApoA1 may be a potential protein-mediated therapeutic for restoring vascular function. Our novel strategy may lead to future clinical trials, furthering our goal of effectively treating ALS patients.\n\nID: 41599384\nTitle: Standardized Hydroxytyrosol-Enriched Olive Pomace Juice Modulates Metabolic and Neurotrophic Signaling Pathways to Attenuate Neuroinflammation and Protect Neuronal Cells.\nAbstract: Olive pomace (OP), a by-product of olive oil production, is a sustainable resource rich in bioactive compounds with potential applications in cosmetics and pharmaceuticals. This study investigates the protective effects of olive pomace juice (OPJ) against H2O2-induced neuronal damage and LPS-induced inflammatory responses in HT22 and BV2 cells, respectively. OPJ suppressed H2O2-induced cell death and exerted anti-apoptotic effects by reducing the BAX/BCL2 ratio and caspase-3 cleavage. OPJ also mitigated neurodegenerative hallmarks by decreasing amyloid fibrils formation and inhibiting \u03b2-secretase and acetylcholinesterase (AChE) activity. Mechanistically, OPJ enhanced antioxidant response by upregulating Nrf2 and its downstream molecule HO-1, along with increasing mRNA levels of antioxidant enzymes, including catalase, SOD1, and GPx. OPJ further activated AMPK\u03b1-SIRT1-PGC1\u03b1 signaling and CREB-BDNF-TrkB signaling, suggesting modulation of key antioxidant, anti-apoptotic, and neurotrophic pathways. In BV2 cells, OPJ downregulated pro-inflammatory cytokines (IL-6 and IL-1\u03b2) and decreased iNOS and COX-2 expression through suppression of NF-\u03baB and MAPK signaling pathways. HPLC analysis identified hydroxytyrosol (10.92%) as the major active compound in OPJ, which compared with tyrosol (2.18%), and hydroxytyrosol exhibited greater neuroprotective and anti-inflammatory effects than tyrosol. This study highlights the potential of OPJ and its major compound, hydroxytyrosol, as functional agents for mitigating neurodegeneration-related cellular response, supporting its application in the food and pharmaceutical industries.\n\nID: 41596266\nTitle: Modulation of the miR-485-3p/PGC-1\u03b1 Pathway by ASO-Loaded Nanoparticles Attenuates ALS Pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron degeneration with limited treatment options. In this study, we investigated the pathological role of microRNA-485-3p (miR-485-3p) in ALS, particularly its regulation of PGC-1\u03b1, a transcriptional coactivator essential for mitochondrial function and neuroprotection. We also evaluated the therapeutic potential of BMD-001S, a nanoparticle-based formulation encapsulating an antisense oligonucleotide targeting miR-485-3p. Our results demonstrated that miR-485-3p expression was significantly elevated in both SOD1G93A-expressing HMC3 microglial cells and in the spinal cords of SOD1G93A transgenic mice at late disease stages, implicating its contribution to ALS pathogenesis. Intravenous administration of BMD-001S effectively reduced miR-485-3p levels and restored PGC-1\u03b1 mRNA and PGC-1\u03b1 protein expression in the spinal cord. These molecular changes were associated with notable therapeutic outcomes, including reduced SOD1 protein aggregation, decreased neuroinflammation, and lower neurofilament light chain concentrations in cerebrospinal fluid. Moreover, BMD-001S treatment was associated with improvements in electrophysiological parameters and preservation of neuromuscular junction integrity during the observation period in SOD1G93A transgenic mice. Taken together, these findings suggest that miR-485-3p/PGC-1\u03b1 pathway is a promising therapeutic target in ALS and support the potential of BMD-001S as a novel treatment strategy for the disease.\n\nID: 41592170\nTitle: The genetics of autosomal recessive ALS: a review of the common forms and their phenotypes.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease marked by progressive degeneration of upper and lower motor neurons. Most forms of ALS associated with a suspected causal variant are inherited in an autosomal dominant manner. However, there is an important subset of autosomal recessive (AR) variants, often associated with early-onset or atypical clinical features. Advances in genetic sequencing have led to increased recognition of AR ALS. In this review, we focus on four key confirmed AR ALS-associated genes, which appear to be most common-ALS2, SPG11, OPTN, and the D90A variant of SOD1-reviewing their pathophysiology and unique clinical manifestations. We also highlight very rare AR mutations implicated in ALS, including SYNE1, ATP13A2, and FUS, and some associated with overlap syndromes or debated pathogenicity including SIGMAR1, ERLIN1, and ERLIN2. These genes are involved in an array of processes including axonal transport, endosomal trafficking, oxidative stress response, and autophagy, suggesting distinct mechanisms of motor neuron degeneration. Some forms of AR ALS more frequently present with juvenile onset and slower progression, but other genes are associated with broader phenotypic spectra. This includes overlap with hereditary spastic paraplegia (HSP) and hereditary ataxias. Understanding these AR forms of ALS may enhance diagnostic precision, improve prognostication, and may pave the way for targeted gene therapies. This review underscores the emerging significance of AR inheritance in ALS and calls for deeper investigation into its molecular and clinical dimensions.\n\nID: 42419281\nTitle: Sealing and healing: A two-step model for plasma membrane repair.\nAbstract: Plasma membrane damage can cause cell death and is associated with neurodegeneration. In this issue of Developmental Cell, Heffner et al. show that annexin A11 (ANXA11) first plugs membrane lesions, before ESCRT-III is recruited to extrude the damaged patch-a two-step repair mechanism compromised by ALS- and FTD-linked mutations.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42389275\nTitle: Role of gut microbiota in melanosis coli: from anthraquinone biotransformation to mucosal homeostasis dysbiosis.\nAbstract: Melanosis coli (MC) is a benign and usually reversible condition characterized by brownish-black pigmentation of the colonic mucosa and is commonly associated with chronic exposure to anthraquinone laxatives (ALs). The best-established histopathological sequence involves AL-related epithelial apoptosis, phagocytosis of apoptotic bodies by macrophages, and subsequent lipofuscin deposition. Emerging evidence suggests that the gut microbiota (GM) may contribute to this process by converting pharmacologically inactive anthraquinone glycosides into active anthrone metabolites, including rhein anthrone. This narrative review summarizes available MC-specific findings and clearly distinguishes them from mechanistic hypotheses extrapolated from constipation, intestinal barrier, and microbiome literature. We discuss microbial \u03b2-glucosidases and reductases involved in AL biotransformation, reported changes in microbial diversity and SCFA-producing taxa in MC or constipation-associated cohorts, and plausible links with barrier dysfunction, bile-acid metabolism, tryptophan-derived metabolites, and LPS-TLR4 signaling. We therefore present the \"Microbiota-Apoptosis Axis\" as a proposed framework rather than a validated causal pathway. Finally, we review GM-targeted strategies, including probiotics, synbiotics, and fecal microbiota transplantation, while emphasizing that direct clinical evidence in MC remains limited and that cessation of anthraquinone laxatives remains the primary management strategy.\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: 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: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\n\nID: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology.\n\nID: 42332177\nTitle: Trace Elements Dyshomeostasis and Toxic Metals Neurotoxicity in Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, are defined by the progressive loss of neurons through interconnected pathological mechanisms, including oxidative stress, mitochondrial dysfunction, protein aggregation, and neuroinflammation. Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases.\n\nID: 42310292\nTitle: Impact of BECLIN1 haploinsufficiency on goblet cell function and susceptibility to colitis.\nAbstract: BECLIN1 is a central regulator of autophagy and endocytic trafficking essential for epithelial homoeostasis. While complete intestinal epithelial loss of BECLIN1 causes fatal enteritis originating in the small intestine, the consequences of its partial loss in the gut remain unclear. Given that BECLIN1 expression can vary in human disease, we investigated whether reduced BECLIN1 is sufficient to impair gut barrier function. Heterozygous Becn1 deletion (Becn1IEC+/-) in the mouse intestinal epithelium caused subtle but significant defects. These included shortened small intestines and altered epithelial architecture, despite preservation of basal autophagy, implicating trafficking-related functions. Supporting this conclusion, Becn1IEC+/- small intestinal epithelial cells showed modest increases in RAB5+ve vesicles, redistribution of E-CADHERIN and F-actin along lateral membranes and altered apico-basal cell morphology. Given the absence of overt small intestinal epithelial disruption or inflammation, as seen with complete loss of BECLIN1, we next addressed whether BECLIN1 insufficiency manifests a phenotype under stress or in other gut regions. Indeed, in the colon, Becn1IEC+/- mice exhibited reduced colonic crypt length, baseline goblet cell loss and reduced mucin production, particularly in mature goblet cells, indicating vulnerability of the mucus barrier. When challenged with dextran sulfate sodium (DSS), Becn1IEC+/- mice exhibited greater weight loss, higher disease activity, more severe histological colitis, and disproportionate loss of neutral mucins, with inflammation confined to the mucosa. Together, these findings show that BECLIN1 insufficiency does not trigger spontaneous inflammation but destabilises epithelial organisation and barrier defence, thereby sensitising the gut to inflammatory challenge and further positioning BECLIN1 as a threshold-dependent determinant of intestinal resilience.\n\nID: 42304926\nTitle: Linking Neurodegeneration and Age-related Macular Degeneration: Unified Pathways and Intervention Strategies.\nAbstract: Age-related macular degeneration (AMD) is caused by the degeneration of photoreceptors and retinal pigment epithelium (RPE) along with drusen deposition and is the leading cause of vision loss in older adults. Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n\nID: 42274555\nTitle: Polypharmacology of Pathway Crosstalk in Neurodegenerative Diseases: Chemical Modulation of Interconnected Signaling Networks.\nAbstract: Neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS), arise from highly interconnected molecular and cellular abnormalities that progressively lead to neuronal dysfunction, synaptic failure, and cell death. This review provides a unified framework to understand the interrelated molecular mechanisms driving these diseases, with a focus on identifying key disease-specific intervention nodes. Core contributors include oxidative stress, mitochondrial dysfunction, protein aggregation, neuroinflammation, and emerging roles of peroxisomal dysfunction in redox imbalance, lipid dysregulation, and inflammatory amplification. Single-target therapies often show limited efficacy due to the complex, interconnected nature of these pathways. In contrast, polypharmacology, which targets multiple disease-relevant mechanisms simultaneously, offers a more promising therapeutic strategy. This review critically examines how pathway crosstalk drives neurodegenerative progression, with particular emphasis on mitochondrial-ROS-inflammatory signaling, aggregation-proteostasis failure, synaptic-neuroimmune dysfunction, and gut-brain communication. It evaluates various multi-node intervention strategies, including multi-target-directed ligands (MTDLs), molecular hybrids, natural products, drug repurposing, and nanocarrier-based delivery systems. Advances in network pharmacology, artificial intelligence (AI), bioinformatics, and multi-omics have enhanced the identification of actionable therapeutic nodes, candidate compounds, and brain-targeted delivery platforms. Notably, the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathways-play distinct roles in neuroinflammation, amplifying neuronal damage by releasing inflammatory cytokines and inducing mitochondrial dysfunction. However, successful translation into clinical practice remains constrained by challenges such as blood-brain barrier penetration, patient heterogeneity, and biomarker limitations. The review advocates for a shift towards mechanism-informed, patient-stratified polypharmacological strategies to better address the network pathology of neurodegeneration, despite significant translational hurdles.\n\nID: 42261159\nTitle: The Pivotal Role of HDAC6 in Amyotrophic Lateral Sclerosis: Neuroprotective Protagonist or Degenerative Adversary?\nAbstract: The review specifically examines the pivotal role of HDAC6 in the pathophysiological pathway of Amyotrophic Lateral Sclerosis (ALS), an escalating neurodegenerative ailment marked by the discerning damage to motor neurons. Several lines of evidence implicate inadequate proteostasis in significantly influencing neuronal degeneration. The accumulation of misfolded proteins and proteotoxicity are highlighted as significant factors in ALS pathophysiology. Key pathological hallmarks include ubiquitin-positive inclusions, disrupted RNA metabolism, cytoskeletal perturbations, and compromised axonal transport systems. HDAC6 dysregulation disrupts axonal transport, impairing mitochondrial function and increasing oxidative stress, leading to rapid motor neuron damage and cell death. The enzyme's aberrant deacetylation of \u03b1-tubulin destabilizes microtubules and impairs intracellular trafficking. Despite HDAC6's participation in these unfavorable processes, it also exerts neuroprotective properties. It deacetylates tubulin, promoting efficient axonal transport and autophagic clearance. HDAC6 helps form aggresomes and stress granules, which are essential for cellular defence against proteotoxic stress. Through its zinc finger ubiquitin-binding domain, HDAC6 interacts with polyubiquitinated proteins, facilitating their autophagic degradation. HDAC6 inhibition can boost autophagic flux and reduce protein aggregation, while its activation may amplify the protective effects. This dichotomous behaviour of HDAC6 may pose an obstacle to the design of targeted therapy. Illuminating the complex mechanisms through which HDAC6 influences neurodegeneration and neuroprotection is important before constructing effective treatments for ALS. The review provides a clear understanding of the complex role of HDAC6 in ALS pathogenesis and highlights potential strategies to improve the prognosis of people affected by this neurological illness.\n\nID: 42246025\nTitle: Editorial: Regulated cell death and neurological diseases.\nAbstract: \n\nID: 42243993\nTitle: Hyperoside protects against poly-GR-mediated neurodegeneration via regulation of mitochondrial fission and oxidative stress in C9orf72-associated ALS.\nAbstract: Arginine-rich poly-glycine-arginine (poly-GR), a toxic dipeptide repeat protein generated from C9orf72 hexanucleotide repeat expansion, drives mitochondrial dysfunction, oxidative stress, and neuronal loss in amyotrophic lateral sclerosis (ALS). Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS.\n\nID: 42242586\nTitle: Early-onset neuroinflammation drives neurodegeneration caused by lysosomal PI(3,5)P2 insufficiency.\nAbstract: Phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2] is a lysosomal signaling lipid whose deficiency, caused by mutations in the PIKfyve complex subunits FIG4 or VAC14, underlies a spectrum of fatal neurologic diseases including Charcot-Marie-Tooth type 4J (CMT4J) and amyotrophic lateral sclerosis (ALS). To map the molecular consequences of PI(3,5)P2 insufficiency in the brain, we performed quantitative proteomic and transcriptomic analyses of three mouse lines bearing distinct loss-of-function mutations in Fig4 or Vac14, examining the brain at the presymptomatic and end stages. Strikingly, profound neuroinflammation was already present at postnatal day 5 (before significant neurodegeneration), characterized by complement activation, interferon signaling, and parenchymal infiltration of peripheral myeloid cells and T-cells. Isolated mutant microglia exhibited a markedly pro-oxidative transcriptional state with elevated reactive oxygen species, a partly non-cell-autonomous phenotype, being present in microglia from mice with conditional Fig4 inactivation in just neurons and astrocytes. Comparison of early (P5) and late (P25) proteomics data revealed that PI(3,5)P2 insufficiency impairs developmental remodeling of the brain proteome: proteins typically upregulated during postnatal maturation failed to accumulate, implicating lysosomal function in neurodevelopment. We identify coordinated elevation of p53, Fas receptor, inflammatory caspases, Gasdermin D, RIPK1, and ZBP1, consistent with multifactorial inflammatory cell death with features of apoptosis, pyroptosis, and necroptosis. Many of the dysregulated proteins are encoded by genes mutated in lysosomal storage disorders, ALS, CMT, Alzheimer's and Parkinson diseases, extending the pathogenic relevance of PI(3,5)P2 insufficiency. Together, these findings establish that early neuroinflammation is a defining - and likely initiating - feature of neurodegeneration caused by disruption of lysosomal PI(3,5)P2.\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=======================================================\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.

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 --- END ACTUAL ABSTRACT FOR 42346121 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material.\" (Source: 42350373)\n- \"We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation.\" (Source: 42350373)\n- \"Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients.\" (Source: 42350373)\n- \"We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology.\" (Source: 42350373)\n- \"Fluoride exposure caused a dose-dependent downregulation of antioxidant and ER stress-related genes and concurrent upregulation of the pro-apoptotic genes.\" (Source: 42165865)\n- \"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.\" (Source: 42184491)\n- \"Nrf2 knockdown via lentiviral shRNA or pharmacological inhibition with brusatol significantly exacerbated BDE-47-induced apoptosis and immune dysfunction\" (Source: 42194024)\n- \"Acridine orange (AO) staining showed increased apoptosis-related fluorescence signals in the head region, with AO-positive puncta density differing significantly among groups.\" (Source: 42190857)\n- \"Histopathological analysis revealed structural damage in hippocampus and cerebral cortex, including neuronal shrinkage, vacuolization, and apoptotic features.\" (Source: 42165865)\n- \"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.\" (Source: 42008072)\n- \"Immunohistochemistry confirmed that EGCG significantly reduced microglial activation, glial fibrillary acidic protein (GFAP) expression, and cleaved caspase-3-positive cells (P<0.01 to P<0.001).\" (Source: 41924369)\n- \"Lisinopril upregulated BI1 protein expression, stabilizing mitochondrial membrane potential and protecting against SOD1G93A-induced apoptosis in NSC34 cells.\" (Source: 41917198)\n- \"Repeated ISO exposure impaired learning and memory, increased anxiety-like behaviors, and caused hippocampal damage, along with elevated pro-apoptotic markers (Bax/Bcl-2 ratio, cleaved caspase-3, PARP1 fragments)\" (Source: 41905503)\n- \"Thioquercetins (thioQ, thioQ(OAc)4, and thioQ(OAc)5), when used at low micromolar range, induced apoptotic cell death in melanoma cells compared to normal cells.\" (Source: 41903067)\n- \"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).\" (Source: 42156174)\n- \"The apoptotic rate of sALS (Day 30: 61.37% \u00b1 9.63%; Day 60: 78.41% \u00b1 6.63%) and SOD1 (Day 30: 73.69% \u00b1 8.81%; Day 60: 60.37% \u00b1 11.53%) -derived MNs was significantly higher than those of HCs at both Day 30 (30.72% \u00b1 7.57%) and Day 60 (50.85% \u00b1 19.36%) (p < 0.001).\" (Source: 41983194)\n- \"The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43.\" (Source: 42351313)\n- \"Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions.\" (Source: 42243993)\n- \"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.\" (Source: 42194024)\n\n\nINSTRUCTION: Study the actual abstracts provided.

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\nKaryoptosis is a distinct form of cell death regulated by the p38 kinase signaling pathway, involving nuclear degeneration and the cellular expulsion of nuclear material, which stands in contrast to classic apoptotic cascades. While the provided literature extensively links SOD1 mutations to apoptotic pathways in ALS\u2014characterized by protein misfolding, aggregation, and the upregulation of markers such as cleaved caspase-3\u2014it does not explicitly establish a causal association between SOD1 mutations and karyoptosis. The literature confirms that karyoptotic features are identified in patients with ALS/FTD pathology, but SOD1's specific role in the karyoptotic pathway remains uncharacterized in the provided dataset.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nKaryoptosis, a unique cell death mechanism mediated by LaminB1 stability and p38 kinase signaling, is observed in ALS/FTD pathology. SOD1-linked ALS is largely characterized by apoptosis, mitochondrial dysfunction, and excitotoxicity. This analysis assesses whether SOD1 links to karyoptosis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe provided literature establishes that karyoptosis is distinct from apoptosis. \"Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material.\" Regulation of this process is tied to specific kinases: \"We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation.\" Conversely, SOD1-related cell death in ALS is firmly rooted in apoptotic models: \"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).\" Although karyoptosis is a known feature of the broader ALS/FTD spectrum (\"We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology\"), current evidence does not explicitly map SOD1-mediated protein aggregation directly to the p38-LaminB1 karyoptotic pathway.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis operates via nuclear lamina destabilization rather than the classical mitochondrial or extrinsic apoptotic pathways.\n* SOD1 mutations represent a well-characterized genetic cause of ALS, but their signaling is primarily linked to caspase-3 dependent apoptosis.\n* The transition of motor neurons into \"disease-associated motor neurons\" (DMs) in SOD1 models suggests a complex, multiphasic state before cell death occurs.\n* While SOD1-ALS models exhibit increased apoptosis, non-SOD1 models (like FTD-associated proteinopathy) often show a wider range of cell death modalities.\n* The absence of SOD1 in the p38/LaminB1 karyoptosis literature suggests these may be parallel or divergent death programs in neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

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."

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."

It is accompanied by profound immune alterations characterized by a progressive decline in immune competence, a process known as immunosenescence. The resulting dysregulation of immune function leads to the overproduction of proinflammatory cytokines and fuels a persistent, low-grade inflammatory state termed inflammaging. This chronic inflammation contributes to dysfunction across the central and peripheral nervous systems, promoting neuronal damage and accelerating neurodegenerative processes such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and other age-related cognitive disorders. Within this framework, prolonged activation of inflammatory pathways can trigger regulated forms of cell death. Among these, necroptosis has recently emerged as a potential mediator linking inflammaging to neurodegeneration. Its core molecular effectors, including the receptor-interacting protein kinases RIPK1 and RIPK3 and the mixed-lineage kinase domain-like protein (MLKL), are increasingly expressed in aged neural tissues, promoting the release of damage-associated molecular patterns (DAMPs) that amplify glial activation, oxidative stress, and blood-brain barrier disruption. Growing evidence suggests that necroptotic signaling may be upregulated in the aging brain and in neurodegenerative disorders, where it could contribute to neuronal loss and cognitive impairment. This review discusses the potential role of necroptosis in the continuum between inflammation and neurodegeneration, highlighting emerging diagnostic and therapeutic perspectives. Epigenetic and circulating biomarkers, such as phosphorylated MLKL and specific microRNAs, may support early detection, while pharmacological and nutraceutical strategies targeting necroptosis show promising neuroprotective effects in preclinical studies."

Evidence has shown that degeneration of cutaneous nerves may reflect neurodegenerative processes occurring within the central nervous system. Although skin biopsy is widely adopted in clinical practice, the procedure is invasive and requires multiple patients' tissue removals. Therefore, we developed a 3D innervated skin model by combining 3D printing of methacrylated hyaluronic acid as an innovative tool for better reproducing the dermis and epidermis and electrospinning of polylactic acid for mimicking skin innervation. Later, 3D artificial skin was colonized with a preneuronal cell line (SH-SY5Y) and fibroblasts isolated from skin biopsy of ALS patients at different disease stages. 3D skin possesses a porosity suitable for cell colonization and a high stability. Importantly, biological results reveal an increase of TAR DNA-binding protein 43 aggregates, NOD-like receptor pyrin domain containing protein 3, interleukin (IL)-18, IL-6, and nitrites in 3D skin of ALS patients, thus indicating pyroptosis activation linked to neurodegeneration.

However, the mechanism by which TDP-43 pathology disrupts microglial function and drives neuroinflammation remains unclear. In this study, we demonstrated that cytoplasmically mis-localized TDP-43 exacerbated neuroinflammation, induced cell death, and impaired phagocytic function in microglial cells, primarily through receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis. Pharmacological inhibition of RIPK3 with GSK872 markedly attenuated these pathological effects in vitro. These findings were further corroborated in a murine model with cytoplasmic TDP-43 mis-localization, where GSK872 treatment remarkably alleviated neuroinflammation and restored cognitive deficits. Mechanistically, our findings indicate that the nuclear depletion of TDP-43, resulted from its cytoplasmic mis-localization, impairs its ability to transcriptionally repress the Ripk3 gene, subsequently leading to RIPK3 upregulation and activation of RIPK3-dependent necroptosis. Collectively, our findings establish RIPK3-dependent necroptosis as a critical driver of TDP-43 pathology-mediated neuroinflammation and identified necroptosis as a promising therapeutic target in TDP-43-associated neurodegenerative disorders."

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.

We hypothesized that a 2.5\u2009Gy dose would induce mitotic failure and cell death, whereas low doses (<1\u2009Gy) might elicit adaptive or hormetic responses. Human U-87\u2009MG glioblastoma cells were cultured on coated glass-bottom dishes, stained with Hoechst 33,342, and maintained at 37\u00b0C/5% CO\u2082. A custom agarose phantom with an embedded dish and metal grid enabled precise delivery of graded SRS doses. CT-based planning localized the dish in the Leksell Gamma Knife Perfexion\u00ae. A single 50% isodose shot delivered 2.5\u2009Gy at the central grid cell (C9), generating adjacent compartments with 2.0, 1.5, 1.0, 0.8, and 0.5\u2009Gy. Live confocal imaging was performed at baseline and at 0, 3, 6, and 24\u2009h post-irradiation. Total cell number and mitotic cells (condensed chromosomes) were quantified per field. Three independent experiments were analyzed using two-way ANOVA with Tukey's post hoc test (\u03b1\u2009=\u20090.05). At 2.5\u2009Gy, cell numbers declined to near zero by 6\u2009h (Mean normalized adherent nuclear count decreased to approximately 5% of baseline.), associated with marked nuclear abnormalities, including multinucleation and nuclear fragmentation. Mitotic figures were absent at all post-SRS time points. Intermediate doses (1.0-1.5\u2009Gy) caused a transient delay: cell counts increased (up to ~150% at 3-6\u2009h, p\u2009<\u20090.05) before declining by 24\u2009h. In contrast, low doses (0.5-0.8\u2009Gy) resulted in net proliferation. The 0.8\u2009Gy group showed a 182% increase in cell count at 24\u2009h (p\u2009=\u20090.01), with a peak mitotic fraction (~12%) at 6\u2009h versus ~2% in controls (p\u2009<\u20090.01). These findings are consistent with radiation hormesis. Two-way ANOVA confirmed significant effects of dose and time (p\u2009<\u20090.001). To our knowledge, this is the first study integrating live-cell imaging with GKRS isodose mapping to assess temporal cellular responses to stereotactic radiosurgery. Gamma Knife SRS induces a dose-dependent response in GBM cells: high doses abolish proliferation, whereas sub-therapeutic doses paradoxically stimulate cell-cycle progression. These findings highlight a potential clinical concern, as low-dose regions may transiently promote tumor growth, but may also be exploited to enhance radiosensitivity."

The results showed that SiNPs significantly suppress porcine oocyte maturation as evidenced by decreased first polar body (PB1) release rate. Notably, SiNPs significantly induced abnormal expansion of cumulus cells and impaired gap junction intercellular communication (GJIC), accompanied by decreased Connexin 43 (CX43) expression and aberrant F-actin structure.

This study investigated the impact of 28 consecutive days of 5-lx ALAN exposure on hippocampal function in C57BL/6\u00a0J mice. We evaluated locomotor behavior, neuronal morphology, neurogenesis, oxidative stress, and circadian rhythms, revealing that ALAN induces cognitive impairment. ALAN exposure reduced Bmal1 expression, increased reactive oxygen species (ROS) and malondialdehyde accumulation, and disrupted the time-of-day-dependent differences expression of NRF2, SOD1, and GPX1. These alterations suppressed SOD and GPX enzymatic activity, leading to hippocampal oxidative damage. To clarify BMAL1's role, we used adeno-associated virus (AAV) to modulate Bmal1 expression in the hippocampus. ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression. These findings suggest that ALAN can contribute to memory impairment by disrupting hippocampal damage and impairing neurogenesis through its effect on Bmal1. This study identifies potential molecular targets for preventing and treating cognitive impairment and neurodegenerative disorders."

The ciliate Paramecium tetraurelia exhibits nuclear dimorphism, harboring two germline micronuclei (MICs) and one somatic macronucleus (MAC) within a single cell during vegetative growth. During sexual reproduction, the MICs undergo meiosis and the MAC deforms and fragments, providing a unique model to study the regulation of diverse nuclear events. Transcription factor DP (TFDP), which heterodimerizes with E2Fs, can bind to specific DNA motifs in promoters of cell cycle-regulated genes to activate or repress their expression. Here, we identified 16 TFDP homologs in P. tetraurelia, representing an exceptional gene family expansion accompanied by functional domain diversification. The functions of Tfdp1a and Tfdp1b, which are specifically expressed during sexual reproduction and localize in the old and new MACs, were further investigated. Their depletion resulted in meiotic arrest at metaphase in the MIC, failure of old MAC fragmentation, and abortive cytokinesis. Transcriptomic analysis revealed that TFDP1A/1B knockdown primarily causes gene downregulation, with\u2009>\u200960% of downregulated genes being specifically highly expressed during sexual reproduction.

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.

Mounting evidence indicates that dysregulated iron metabolism and an imbalance in antioxidant defenses can induce ferroptosis in neurons and glial cells while simultaneously remodeling immune cell function, thereby establishing a bidirectional feedback loop that amplifies neuroinflammation and tissue damage. In neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), pro-inflammatory cytokines such as TNF-\u03b1 and IL-1\u03b2 released by activated microglia upregulate neuronal iron transporters (e.g., DMT1 and TfR1), promoting iron accumulation and ferroptotic cell death. In turn, damage-associated molecular patterns released from ferroptotic cells further potentiate immune activation, forming a self-amplifying cycle. In contrast, within the glioma microenvironment, CD8+ T cell-derived IFN-\u03b3 suppresses SLC7A11 expression in tumor cells, leading to glutathione depletion and glutathione peroxidase 4 inactivation, thereby triggering ferroptosis and modulating anti-tumor immunity. Although targeting ferroptosis or neuroimmune pathways has shown therapeutic promise in mitigating neurological deficits and enhancing anti-tumor responses, the underlying mechanisms governing ferroptosis-immune crosstalk remain inadequately characterized. Herein, this review systematically summarizes the key biological characteristics of ferroptosis and immune responses, with particular emphasis on their interplay across major CNS disorders (i.e., AD, PD, ALS, multiple sclerosis, stroke, and glioma). Furthermore, we discuss emerging therapeutic strategies encompassing small molecules, immunomodulatory approaches, and nanotechnology-based interventions, highlighting the ferroptosis-immune axis as a promising therapeutic target for CNS diseases."

In this review, we examine the potential involvement of disulfidptosis in neurodegenerative diseases from a disease-centered perspective. We emphasize that current evidence is largely indirect and based on mechanistic overlap rather than direct experimental validation in neural systems. Accordingly, we distinguish between direct evidence, indirect mechanistic support, and pathophysiological plausibility. We further discuss cell-type-specific susceptibility across neurons and glial cells, analyze its relationship with other cell death pathways, and consider potential therapeutic implications. Overall, disulfidptosis is best regarded as a context-dependent and emerging mechanism that may contribute to neuronal vulnerability under specific metabolic and redox constraints. Clarifying its disease relevance will be essential for determining its significance in neurodegeneration and its potential as a therapeutic target."

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.

Ferritin, characterized by a 24\u2011subunit hollow sphere structure composed of heavy and light chains, plays a key role in the network regulating cerebral iron homeostasis. In response to cellular iron overload, ferritin expression is upregulated to sequester labile iron and mitigate Fenton reaction\u2011mediated toxicity, thus exerting a cytoprotective function. Paradoxically, ferritin can be degraded via ferritinophagy, a selective autophagic process that releases toxic ferrous iron and directly triggers ferroptosis. This review systematically reviews the role of ferritin within the iron homeostasis network to elucidate the connection between the dysregulation of iron metabolism and the pathological mechanisms of neurodegenerative diseases. The study focused on the potential role of ferritin as a biomarker for early diagnosis, therapeutic strategies targeting ferritin pathways to restore iron homeostasis and the clinical translational value of magnetic resonance imaging\u2011based non\u2011invasive quantification of cerebral iron deposition. It is crucial to elucidate the multidimensional roles of ferritin in neurodegeneration to provide a theoretical foundation for precision diagnostic and therapeutic approaches."

However, the mechanism by which TDP-43 pathology disrupts microglial function and drives neuroinflammation remains unclear. In this study, we demonstrated that cytoplasmically mis-localized TDP-43 exacerbated neuroinflammation, induced cell death, and impaired phagocytic function in microglial cells, primarily through receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis. Pharmacological inhibition of RIPK3 with GSK872 markedly attenuated these pathological effects in vitro. These findings were further corroborated in a murine model with cytoplasmic TDP-43 mis-localization, where GSK872 treatment remarkably alleviated neuroinflammation and restored cognitive deficits. Mechanistically, our findings indicate that the nuclear depletion of TDP-43, resulted from its cytoplasmic mis-localization, impairs its ability to transcriptionally repress the Ripk3 gene, subsequently leading to RIPK3 upregulation and activation of RIPK3-dependent necroptosis. Collectively, our findings establish RIPK3-dependent necroptosis as a critical driver of TDP-43 pathology-mediated neuroinflammation and identified necroptosis as a promising therapeutic target in TDP-43-associated neurodegenerative disorders."

Disruptions of MAM integrity and prolonged ER stress are well-recognized pathological features of amyotrophic lateral sclerosis (ALS), contributing to motor neuron dysfunction and degeneration. In this study, we evaluated the protective effects of pridopidine, a highly selective and potent S1R agonist currently in clinical development for Huntington's disease (HD) and ALS, using neural progenitor cells (NPCs) derived from induced pluripotent stem cells (iPSCs) from a patient with sporadic ALS. Exposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted mitochondrial membrane potential, upregulated expression of the mitochondrial apoptotic marker, BAX, increased caspase-3 activation, and reduced cell viability. Pridopidine significantly attenuated tunicamycin-induced BiP and CHOP expression in a biphasic, dose-dependent manner (with maximal efficacy at 1 \u00b5M), consistent with the typical pharmacology of S1R agonists. Pridopidine restored mitochondrial membrane potential, reduced mitochondrial apoptotic signaling, shown by decreased BAX expression and caspase-3 activation, and improved survival of ALS-NPCs under ER stress. Co-treatment with the selective S1R antagonist, NE-100, attenuated these effects, supporting an S1R-mediated mechanism of action for pridopidine. Together, these results demonstrate that S1R activation by pridopidine mitigates ER-stress-induced mitochondrial dysfunction and cell loss in ALS-NPCs, resulting in enhanced survival of NPCs supporting the therapeutic potential of pridopidine in ALS."

SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?)\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis assessment synthesizes current evidence on distinct cell death modalities in neurodegeneration, specifically differentiating karyoptosis from apoptosis. It further evaluates the specific association between superoxide dismutase 1 (SOD1) and cell death mechanisms, including its role in apoptosis and its potential link to karyoptotic pathology in amyotrophic lateral sclerosis (ALS).\n\n### [INTRODUCTION & JUSTIFICATION]\nKaryoptosis constitutes a distinct form of cell death regulated by the p38 kinase signaling pathway, which controls the stability of the nuclear lamina protein LaminB1 via direct phosphorylation. In contrast, apoptosis in ALS-linked models often involves oxidative stress-mediated pathways and specific genetic contributions like SOD1 mutations. While SOD1 mutations are well-documented to induce apoptosis, direct empirical evidence linking SOD1 protein specifically to the induction of karyoptosis remains limited or absent in the provided dataset. Both processes appear to represent distinct, though sometimes convergent, pathways of neuronal loss in proteotoxic conditions.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the cellular expulsion of nuclear material, a morphological feature distinct from the chromatin condensation and membrane blebbing typical of classical apoptosis.\n* SOD1 mutations in ALS are traditionally linked to protein misfolding, aggregation, and the subsequent induction of apoptosis.\n* The p38 kinase signaling pathway serves as a regulatory switch for karyoptotic cell death by modulating nuclear lamina structural integrity.\n* Neurodegeneration in ALS/FTD pathology involves complex crosstalk between different regulated cell death forms, including apoptosis, ferroptosis, necroptosis, and karyoptosis.\n* Systemic iron homeostasis and the sequestration of labile iron by ferritin are critical, as their dysregulation triggers ferroptosis, which often overlaps with the stressors inducing apoptosis and karyoptosis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

HGC-27 cell xenografts were established in Balb/c-nu mice. After tumor formation, mice were allocated into a low-dose(7.5 g\u00b7kg~(-1) per day) JHJD group, a high-dose(15 g\u00b7kg~(-1) per day) JHJD group, and a model group. The mice in the JHJD groups were administrated with corresponding doses of JHJD and those in the model group with an equal volume of normal saline by gavage. The body mass, subcutaneous xenograft volume, and tissue mass of the mice were measured, and the tumor inhibition rate was calculated. The pathological changes of the xenograft tissue in each group were observed under a microscope after hematoxylin-eosin(HE) staining. The ROS level in the tissue was measured by a ROS kit, and the mRNA levels of PARP1 and GSDME in the xenograft were determined by RT-qPCR. HGC-27 cells were assigned into 5%, 10%, and 15% blank serum groups and 5%, 10%, and 15% JHJD-containing serum groups. Cell viability was detected by the CCK-8 assay, and intracellular ROS levels were quantified by the ROS kit. The morphological changes of cells were observed under a microscope. The protein levels of PARP1 and GSDME were determined by Western blot. The lactate dehydrogenase(LDH) release rate and adenosine triphosphate(ATP) levels in the cell supernatant were determined by LDH and ATP kits, and high mobility group box-1 protein(HMGB1) levels in the cell supernatant were determined by ELISA. In vivo experiments revealed that the low-and high-dose JHJD groups had lower volume and mass of subcutaneous xenografts than the model group(P<0.05), with the tumor inhibition rates of 20.43% and 30.75%, respectively. HE staining showed that cells in the model group exhibited pleomorphism, clustered arrangement, and nuclear division. Cells in the low-dose JHJD group showed reduced nuclear volume, deeply stained nuclei, lack of mitotic figures, and numerous vacuoles. Cells in the high-dose JHJD group showed nuclear pyknosis, nuclear fragmentation, and numerous cell debris. The mRNA levels of PARP1 and GSDME and the levels of ROS in the tissue in both the low-dose and high-dose JHJD groups raised compared with those in the model group(P<0.05). In vitro experiments showed that serum containing JHJD at all concentrations inhibited the proliferation of HGC-27 cells at the time points of 24, 48, and 72 h(P<0.05), and the inhibitory effect increased in a concentration-dependent manner. Morphological features of pyroptosis, including swelling, rupture, and release of vesicular contents at the cell edges, were induced by JHJD-containing serum to varying degrees, being the most pronounced in the 15% JHJD-containing serum group. The ROS levels and the protein levels of PARP1 and GSDME in all JHJD-containing serum groups were higher than those in the 5% blank serum group(P<0.05), and the differences between JHJD-containing serum groups were significant(P<0.05). Compared with the 5% blank serum group, JHJD-containing serum increased the LDH release rate and the ATP and HMGB1 levels in the supernatant(P<0.05) in a concentration-dependent manner, and the differences between groups were significant(P<0.05). In conclusion, JHJD may inhibit the proliferation of gastric cancer HGC-27 cells by inducing pyroptosis through upregulating the ROS/PARP1/GSDME pathway.\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 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), 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 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, 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: 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: 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: 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: 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: 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: 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: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.\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: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology.\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: 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: 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: 42304808\nTitle: Amyotrophic Lateral Sclerosis Recovery: A New Model System of Care Integrating Neuromuscular Rehabilitation With Clinical Stabilization in ALS.\nAbstract: There is currently no consensus on how to define recovery for individuals with amyotrophic lateral sclerosis (ALS). Tofersen treatment for superoxide dismutase-1-related (SOD1) ALS marks a pivot in clinical management: for the first time, clinicians can target disease stabilization and functional recovery in some individuals. This advancement shifts the focus of ALS care toward optimizing functional recovery alongside symptomatic management. However, there are no evidence-based guidelines for prescribing neuromuscular rehabilitation (NMR) to improve functional recovery. Building on our preliminary single-center data of integrated NMR with tofersen, we propose a new ALS Recovery Model System of Care, utilizing a hub-and-spoke infrastructure to combine NMR with novel therapies. This model aims to define ALS recovery, characterize recovery profiles, standardize NMR protocols, and establish a rehabilitation framework adaptable to future disease-stabilizing therapies.\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: 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: 42265995\nTitle: Two Patients With Juvenile-Onset, Rapidly Progressive Amyotrophic Lateral Sclerosis Associated With an SOD1 Variant (p.Asp125Gly) With Incomplete Penetrance.\nAbstract: Amyotrophic lateral sclerosis (ALS) patients are rarely encountered before age 25\u2009years, often associated with genetic variants. SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies.\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: 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: 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: 42416895\nTitle: The Eight\u2011Chop Technique in Cataract Surgery: A Conceptual and Narrative Review of a Segmentation\u2011First Strategy.\nAbstract: To review the conceptual evolution, mechanical principles, and clinical performance of the Eight-Chop Technique and to clarify its role within contemporary cataract surgery. This narrative, concept\u2011driven review summarizes the historical development of nuclear fragmentation strategies, including sculpting-based techniques, divide-and-conquer, chop-based methods, femtosecond laser-assisted cataract surgery, and prechop techniques. A non\u2011systematic literature search of PubMed and Google Scholar was performed for articles published between 1991 and 2025 using combinations of the terms \"cataract\", \"phacoemulsification\", \"nuclear fragmentation\", \"phaco-chop\", \"prechop\", and \"eight-chop\". Adult human cataract surgery studies and key conceptual articles on nuclear segmentation and intraoperative fluidics were selectively included. Because most available clinical reports originate from the originating surgeon and closely affiliated groups, the evidence base is limited and heterogeneous, and formal systematic evidence synthesis was not attempted. Particular attention was directed toward the wedge-induced fracture mechanism, geometric optimization through eightfold nuclear division, and compatibility with modern fluidics systems. Published clinical studies together with the author's clinical experience were reviewed across a broad spectrum of cataract subtypes. In both standard cataracts and challenging conditions-including hard nuclear cataracts, white cataracts, small pupils, shallow anterior chamber, microcornea, diabetic eyes, and pseudoexfoliation syndrome-the Eight-Chop Technique has been reported to be associated with reduced phaco time, cumulative dissipated energy, and irrigation volume compared with conventional techniques. Corneal endothelial cell density loss was generally limited to approximately 0.9-6.7%, even in high-risk subgroups. Postoperative intraocular pressure also demonstrated sustained reduction during mid- to long-term follow-up. These findings are encouraging but preliminary and may partly reflect surgeon experience, case selection, and contemporary phacoemulsification platforms. The Eight\u2011Chop Technique is a segmentation\u2011first nuclear fragmentation strategy based on complete in\u2011the\u2011bag prefragmentation using a wedge\u2011induced fracture mechanism. Its conceptual compatibility with modern fluidics systems, including active fluidics platforms, may contribute to improved anterior chamber stability and a minimally invasive surgical profile. However, because current evidence is derived largely from single\u2011surgeon and closely affiliated studies, the clinical advantages of the Eight\u2011Chop Technique should be regarded as provisional. Independent, multicenter validation and randomized comparative trials are required before definitive conclusions can be drawn regarding its overall clinical superiority and generalizability.\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: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42399370\nTitle: Therapeutic targeting of the conserved region within the low-complexity domain of TDP-43 is neuroprotective and extends survival in amyotrophic lateral sclerosis mice.\nAbstract: Autosomal dominant mutations in TARDBP, encoding TAR DNA-binding protein 43 (TDP-43), cause amyotrophic lateral sclerosis (ALS), and TDP-43 pathology is a hallmark of multiple aging-associated neurodegenerative diseases. Despite its pathological role, effective therapies remain limited by the lack of safe, potent molecules targeting TDP-43 neurotoxicity. Here we show that the conserved \u03b1-helical region spanning residues 320-340 (conserved region or CR) is a therapeutically actionable target for TDP-43 neurotoxicity. Deletion of CR markedly suppressed TDP-43-induced neuronal death. Structure-based virtual screening identified XL20, a brain-penetrant small molecule that engages CR and confers neuroprotection without affecting TDP-43 splicing activity. XL20 alleviated motor neuron loss, extended survival in TDP-43 p.Ala315Thr ALS mice and enhanced neuronal function in p.Gln331Lys induced pluripotent stem cell-derived human ALS motor neurons. Mechanistically, targeting CR suppressed TDP-43 mitochondrial localization and restored mitochondrial function, likely through liquid-liquid phase separation. Our findings highlight CR as a therapeutic target for TDP-43-associated neurodegeneration and support CR-binding small molecules as therapeutic candidates.\n\nID: 42392815\nTitle: [Effect of schaftoside in inhibiting aspirin-induced gastric mucosal injury by targeting PYGB].\nAbstract: This study investigated the effect and mechanism of schaftoside(Xftg) against aspirin-induced gastric mucosal injury in mice. Aspirin-induced human gastric mucosal epithelial cell(GES-1) model and gastric mucosal injury model of mice were employed. The CCK-8 assay was used to detect the impact of different concentrations of Xftg on the viability of GES-1. Cell morphology was detected by using Hoechst 33342 fluorescent staining. Hematoxylin-eosin(HE) staining was employed to observe the mouse gastric tissue morphology. The expression levels of zonula occludens-1(ZO-1) and Occludin were detected by immunofluorescence. Mucin 2(MUC2) expression was measured via immunohistochemistry. Levels of interleukin(IL)-6, IL-1\u03b2, tumor necrosis factor-\u03b1(TNF-\u03b1), cyclooxygenase(COX)-1, and prostaglandin E2(PGE2) in serum were determined by enzyme-linked immunosorbent assay(ELISA). Target proteins were screened by using limited enzymatic digestion. The level of glycogen phosphorylase B(PYGB) in gastric tissue was determined by ELISA. Protein expression in gastric tissues was detected by Western blot. The results show that Xftg in vitro increases the viability and ameliorates nuclear fragmentation of aspirin-induced GES-1. In vivo, Xftg alleviates the weight loss of model mice with gastric mucosa injury and pathological damage of the gastric mucosa. It also increases the expression of Occludin and ZO-1 proteins in gastric tissue, normalizes MUC2 protein expression, elevates levels of COX-1 and PGE2 in serum, and reduces levels of IL-6, IL-1\u03b2, and TNF-\u03b1 in serum. PYGB is identified as a potential target of Xftg by using limited enzymatic digestion. ELISA and Western blot experiments confirm that Xftg significantly downregulates PYGB protein expression in the gastric tissue of mice. In conclusion, Xftg may inhibit aspirin-induced gastric mucosal injury effect by targeting PYGB and downregulating PYGB protein expression.\n\nID: 42391810\nTitle: Assessing the cytotoxic effects of group IX metal N-heterocyclic carbene complexes of iridium and rhodium on B16-F10 melanoma and non-cancerous RAW 264.7 cells.\nAbstract: The development of highly effective and selective anticancer agents remains a central challenge in oncological research. Herein, we report a systematic evaluation of the anticancer activity of a series of rhodium- and iridium-based NHC (N-heterocyclic carbene) complexes (complexes 1, 3, 5-7), including the novel complex 3, as well as two imidazole-containing complexes (2 and 4). Their cytotoxic profiles were investigated against B16-F10 melanoma cells and benchmarked against non-cancerous RAW 264.7 macrophage cells to assess cancer selectivity. Cytotoxicity of complexes 1-7 was quantified using the crystal violet assay following exposure to 0.01\u00a0mM and 0.1\u00a0mM concentrations over 24, 48, and 72\u00a0h. Half-maximal inhibitory concentrations (IC50) were determined to establish comparative selectivity and potency indices. Mechanistic insight was further obtained through morphological assessment of treated cells at IC50 values using polarised light optical differential interference contrast (PlasDIC) microscopy. At 0.1\u00a0mM, all complexes induced a pronounced reduction in B16-F10 cell viability, with complexes 2 and 3 emerging as the most potent, achieving >90% inhibition after 72\u00a0h. Notably, early time-point IC50 values (24\u00a0h) revealed marked cytotoxicity in melanoma cells (complex 2: 0.04\u00a0mM; complex 3: 0.05\u00a0mM), while eliciting minimal effects in RAW 264.7 macrophages, indicating selective anti-cancer activity. Morphological analysis of B16-F10 cells demonstrated features consistent with both apoptosis (membrane blebbing, apoptotic bodies, nuclear fragmentation) and necrosis (cell swelling, debris). Cell cycle analysis demonstrated a general increase in the S phase in B16-F10 cells, indicative of replication stress or cell cycle arrest, whereas no significant changes were observed in RAW 264.7 cells. Collectively, complexes 2, 3, and 5, display a compelling combination of potency and selectivity towards B16-F10 melanoma cells, with reduced cytotoxicity towards non-cancerous RAW 264.7 cells. These results support the continued development of NHC-based metal complexes as promising selective anticancer agents and warrant further mechanistic and in vivo investigation.\n\nID: 42390647\nTitle: Real-time confocal imaging for evaluation of dose-dependent effects of gamma knife radiosurgery on U87 glioblastoma cell line.\nAbstract: To characterize, in real time, how single-fraction low-dose Gamma Knife stereotactic radiosurgery (GKRS) affects proliferation and cell-cycle dynamics in glioblastoma (GBM) cells across a range of doses. We hypothesized that a 2.5\u2009Gy dose would induce mitotic failure and cell death, whereas low doses (<1\u2009Gy) might elicit adaptive or hormetic responses. Human U-87\u2009MG glioblastoma cells were cultured on coated glass-bottom dishes, stained with Hoechst 33,342, and maintained at 37\u00b0C/5% CO\u2082. A custom agarose phantom with an embedded dish and metal grid enabled precise delivery of graded SRS doses. CT-based planning localized the dish in the Leksell Gamma Knife Perfexion\u00ae. A single 50% isodose shot delivered 2.5\u2009Gy at the central grid cell (C9), generating adjacent compartments with 2.0, 1.5, 1.0, 0.8, and 0.5\u2009Gy. Live confocal imaging was performed at baseline and at 0, 3, 6, and 24\u2009h post-irradiation. Total cell number and mitotic cells (condensed chromosomes) were quantified per field. Three independent experiments were analyzed using two-way ANOVA with Tukey's post hoc test (\u03b1\u2009=\u20090.05). At 2.5\u2009Gy, cell numbers declined to near zero by 6\u2009h (Mean normalized adherent nuclear count decreased to approximately 5% of baseline.), associated with marked nuclear abnormalities, including multinucleation and nuclear fragmentation. Mitotic figures were absent at all post-SRS time points. Intermediate doses (1.0-1.5\u2009Gy) caused a transient delay: cell counts increased (up to ~150% at 3-6\u2009h, p\u2009<\u20090.05) before declining by 24\u2009h. In contrast, low doses (0.5-0.8\u2009Gy) resulted in net proliferation. The 0.8\u2009Gy group showed a 182% increase in cell count at 24\u2009h (p\u2009=\u20090.01), with a peak mitotic fraction (~12%) at 6\u2009h versus ~2% in controls (p\u2009<\u20090.01). These findings are consistent with radiation hormesis. Two-way ANOVA confirmed significant effects of dose and time (p\u2009<\u20090.001). To our knowledge, this is the first study integrating live-cell imaging with GKRS isodose mapping to assess temporal cellular responses to stereotactic radiosurgery. Gamma Knife SRS induces a dose-dependent response in GBM cells: high doses abolish proliferation, whereas sub-therapeutic doses paradoxically stimulate cell-cycle progression. These findings highlight a potential clinical concern, as low-dose regions may transiently promote tumor growth, but may also be exploited to enhance radiosensitivity.\n\nID: 42385702\nTitle: Recurrent patterns of TOP1-mediated neuronal genomic damage shared by major neurodegenerative disorders.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD) represent two major categories of neurodegenerative disorders-TAR DNA-binding protein 43 (TDP-43) and tau proteinopathies-for which the mechanisms driving neuronal death remain unclear. Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.\n\nID: 42352309\nTitle: Mitochondrial Dynamics and SLC25 Transporters in Neurodegeneration: From Mechanisms to Therapeutic Opportunities.\nAbstract: Neurodegenerative diseases are increasingly recognized as disorders of due to disrupted cellular homeostasis, with mitochondrial dysfunction playing a central and early role in disease progression. This review explores the intricate relationship between mitochondrial function and neuronal health, emphasizing the pivotal role of the solute carrier family 25 (SLC25) transporters in maintaining mitochondrial homeostasis. We provide a comprehensive overview of mitochondrial biology in the central nervous system, including energy metabolism, calcium signaling, redox regulation, organelle interactions and mitochondrial dynamics. We delve into the SLC25 transporter family, highlighting their transport mechanisms, substrates and roles in brain metabolism and neuroprotection. SLC25 on one hand and proteins involved in the regulation of mitochondrial morphology and calcium signaling on the other hand are two sides of the same coin influencing each other. A critical analysis follows, examining how mitochondrial dysfunction contributes to mitochondrial abnormalities in a spectrum of neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, ALS and rare mitochondrial encephalopathies. Finally, we assess emerging therapeutic strategies targeting mitochondrial pathways and SLC25 function, including metabolic modulation, gene therapies, antioxidants and pharmacological agents. This review underscores mitochondria and the SLC25 transporters as promising targets for disease-modifying interventions in neurodegeneration and raises key questions about the causality between mitochondrial failure and neuronal death.\n\nID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\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: 42327318\nTitle: Mutant SOD1 expressed by oligodendrocytes aggregates in myelinic nanochannels and accelerates disease progression in familial ALS mice.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a highly debilitating and fatal disease characterized by the progressive loss of motor neurons. Reduced oligodendroglial support has been implicated in ALS progression but remains mechanistically unexplained. Here, using a mutant superoxide dismutase 1 (SOD1-G37R) mouse model of familial ALS, Cre-mediated excision of the mutant SOD1 gene within the oligodendrocyte lineage prior to myelin compaction is shown to slow disease onset, improve motor performance, and prolong survival. In contrast, silencing mutant SOD1 expression within oligodendrocytes after myelin compaction failed to ameliorate disease phenotype. Electron microscopy is used to identify aggregation of mutant SOD1 within paranodal loops and the inner periaxonal tongue of 'myelinic nanochannels', narrow cytosolic compartments for the diffusion of metabolites and motor-driven transport processes. In a second mouse model (SOD1-G93A) of familial, SOD1 mutant-mediated ALS, we show that induction of excessive myelin compaction and myelinic channel collapse (by depletion of CNP from myelin) accelerates disease and diminishes survival. Our data support loss of myelinic channel integrity as a contributor to familial ALS disease initiation and progression, findings likely relevant to neurodegenerative disease involving other aggregation prone proteins that are expressed in myelinating oligodendrocytes. Oligodendrocytes have been implicated in the progression of amyotrophic lateral sclerosis (ALS) but the underlying mechanisms have remained obscure. Here we show in genetic mouse models that the familial ALS causing isoform of a ubiquitously expressed mutant enzyme (SOD1) aggregates in cytosolic channels within myelin that are responsible for delivery of transporters and nutrients necessary to support the axonal compartment. ALS disease progression was accelerated in mice when myelinic channels were collapsed by deleting CNP, a structural protein necessary for myelinic channel maintenance. Disruption of transport through myelinic channels by aggregation of mutant SOD1 may perturb oligodendrocyte support of motor axons and contribute to disease in this form of ALS.\n\nID: 42324741\nTitle: Impacts of curcumin nanoemulgel on cell viability and apoptotic pathways: a comprehensive study of ROS generation across different skin cancer cell lines.\nAbstract: Conventional curcumin formulations, such as gels, creams, and oral dosage forms, have poor solubility and bioavailability, limiting its therapeutic efficiency. Therefore, the primary objective of this research work was to formulate a curcumin nanoemulgel to increase the solubility and therapeutic efficacy of curcumin and evaluate its cytotoxic, apoptotic, and Reactive oxygen species (ROS) activities against various cell lines. A curcumin nanoemulgel was formulated by adding the optimized curcumin nanoemulsion to plain carbopol gel and then subjected to various evaluation studies. The optimized curcumin nanoemulgel exhibited better growth suppression of cancer cell lines, especially in A431 squamous cell carcinoma cells, with an inhibition percentage of 66.52\u2009\u00b1\u20091.3% an IC50 value of 123.30\u2009\u00b5M. Flow cytometry analysis revealed that curcumin nanoemulgel promoted apoptosis, with larger percentages of late apoptotic cells in A431 cells. The dual AO/EB fluorescence microscopy revealed distinctive apoptotic characteristics, including chromatin condensation, nuclear fragmentation, membrane blebbing, and the formation of apoptotic bodies. All of these results demonstrate that the nanoemulgel formulation is a superior therapeutic choice as it not only enhances curcumin's anticancer effectiveness but also ensures its safety in healthy cells.\n\nID: 42278136\nTitle: Antioxidant Activity of Stallion Spermatozoa After Cryopreservation with Natural Antioxidant-Supplemented Extenders.\nAbstract: Cryopreservation of stallion semen is associated with oxidative stress (OS), which can impair sperm function and fertility. This study evaluated antioxidant activities in seminal plasma and sperm cytosols and investigated their relationships with selected sperm functional parameters following cryopreservation, with or without antioxidant supplementation. Semen was collected from ten fertile stallions and processed using a split-ejaculate design, including fresh semen and six freezing treatments: HF-20 extender alone; HF-20 supplemented with matcha, spirulina, horseradish, or quercetin; and a commercial extender (INRA Freeze). Total antioxidant capacity (FRAP) and enzymatic activities (superoxide dismutase, SOD; catalase, CAT; and glutathione reductase, GR) were measured in seminal plasma and sperm lysates. Linear regression analyses revealed significant associations between seminal plasma and fresh spermatozoa with respect to SOD and GR activities. In frozen-thawed semen, FRAP and CAT activities differed between samples cryopreserved with and without antioxidant supplementation. Significant correlations were observed among antioxidant activities, sperm kinetics, OS markers, and DNA fragmentation indices. Principal component analysis provided an exploratory overview of multidimensional patterns of covariation among sperm kinetics, redox balance, and nuclear fragmentation, explaining for 73% of the total variance. Overall, the results suggest complex associations between the antioxidant system and sperm quality and indicate that antioxidant supplementation of freezing extenders may modulate the redox status of stallion sperm after thawing.\n\nID: 42236747\nTitle: Targeting mitophagy for neuroprotection: mechanisms and therapeutic opportunities.\nAbstract: Mitochondria are essential for neuronal energy production, cellular homeostasis, and overall neuronal function. Due to their high metabolic demands and limited regenerative capacity, neurons are particularly vulnerable to mitochondrial dysfunction, which leads to ATP depletion, excessive reactive oxygen species (ROS) production, and calcium imbalance-ultimately causing oxidative stress, metabolic disruption, and neuronal death. Mitophagy is a selective process that removes damaged mitochondria through the autophagy-lysosome pathway. As a key mechanism of mitochondrial quality control, mitophagy preserves energy production, limits oxidative damage, and maintains mitochondrial network integrity. This process is regulated by pathways such as PINK1-Parkin and receptor-mediated mechanisms involving BNIP3 and FUNDC1, all of which help sustain cellular health by preventing mitochondrial dysfunction. Impaired mitophagy is a common feature of several neurodegenerative diseases, including Alzheimer's, Parkinson's, amyotrophic lateral sclerosis (ALS), and Huntington's disease, exacerbating mitochondrial damage and neuronal stress. Emerging therapeutic strategies that target mitophagy-ranging from pharmacological agents and gene therapies to dietary interventions-show promise in restoring mitochondrial quality and protecting neurons from degeneration. Nevertheless, challenges remain in translating these findings into effective clinical treatments. Mitophagy represents a critical mechanism for preserving neuronal integrity and offers a compelling target for innovative therapies against neurodegenerative disorders.\n\nID: 42227424\nTitle: [Loganetin Induces AML Cell Differentiation and Chromosomal Instability via KLHL6-Mediated CDK2 Ubiquitination Degradation].\nAbstract: To investigate how loganetin, an active compound from Cornus officinalis, inhibits acute myeloid leukemia (AML) by regulating CDK2 ubiquitination-mediated degradation. Human AML MOLM-13 cells were treated with gradient concentrations (0, 120, 240, 480 \u03bcmol/L) of loganetin for 48 hours. CDK2 protein expression and its interaction with KLHL6 were analyzed by Western blot and co-immunoprecipitation (Co-IP), respectively. Cellular morphology was observed via Giemsa staining. Intracellular oxidative stress was evaluated by NBT assay. An AML mouse model was established by tail-vein injection of MOLM-13 cells (1\u00d7107/mL, 2\u00d7106 cells/mouse); bone marrow cells were analyzed by flow cytometry for hCD45+ and CD11b+ surface markers. Loganetin dose-dependently induced KLHL6-mediated CDK2 ubiquitination and degradation. The Western blot analysis results showed that the level of CDK2 protein significantly decreased with the increase of loganetin concentration (P <0.01), Co-IP confirmed that the CDK2-KLHL6 interaction was enhanced in a dose-dependent manner. Giemsa staining revealed morphological changes (e.g., multinucleated cells, nuclear fragmentation) indicative of chromosome instability in high-concentration groups (480 \u03bcmol/L). NBT assay demonstrated elevated intracellular oxidative stress (P <0.01), accompanied by downregulation of PRDX2 and upregulation of MAFB. In vivo, treated mice showed reduced bone marrow hCD45+ AML cells (P <0.05) and increased CD11b+ differentiated cells (P <0.05), and the splenomegaly was alleviated. Loganetin promotes AML cell differentiation by degrading CDK2 via KLHL6-mediated ubiquitination, synergistically enhancing oxidative stressand genomic instability. \u9a6c\u94b1\u82f7\u5143\u901a\u8fc7KLHL6\u4ecb\u5bfcCDK2\u6cdb\u7d20\u5316\u964d\u89e3\u8bf1\u5bfcAML\u7ec6\u80de\u5206\u5316\u53ca\u67d3\u8272\u4f53\u4e0d\u7a33\u5b9a\u6027. \u63a2\u7a76\u5c71\u8331\u8438\u6d3b\u6027\u6210\u5206\u9a6c\u94b1\u82f7\u5143\u8c03\u63a7CDK2\u6cdb\u7d20\u5316\u964d\u89e3\u6291\u5236\u6025\u6027\u9ad3\u7cfb\u767d\u8840\u75c5\uff08AML\uff09\u7684\u4f5c\u7528\u673a\u5236\u3002. \u91c7\u7528\u68af\u5ea6\u6d53\u5ea6\uff080\u3001120\u3001240\u3001480 \u03bcmol/L\uff09\u9a6c\u94b1\u82f7\u5143\u5904\u7406MOLM-13\u7ec6\u80de48 h\uff0cWestern blot\u68c0\u6d4bCDK2\u86cb\u767d\u8868\u8fbe\uff0cCo-IP\u68c0\u6d4bCDK2\u4e0eKLHL6\u76f8\u4e92\u4f5c\u7528\uff1b\u5409\u59c6\u8428\u67d3\u8272\u89c2\u5bdf\u7ec6\u80de\u5f62\u6001\u53d8\u5316\uff1bNBT\u5b9e\u9a8c\u8bc4\u4f30\u7ec6\u80de\u6c27\u5316\u5e94\u6fc0\u6c34\u5e73\u3002\u5efa\u7acb\u5c0f\u9f20AML\u6a21\u578b\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u5206\u6790\u9aa8\u9ad3\u7ec6\u80de\u8868\u9762hCD45+\u53caCD11b+\u7684\u8868\u8fbe\u3002. \u9a6c\u94b1\u82f7\u5143\u5242\u91cf\u4f9d\u8d56\u6027\u8bf1\u5bfcKLHL6\u4ecb\u5bfc\u7684CDK2\u6cdb\u7d20\u5316\u964d\u89e3\u3002Western blot\u5206\u6790\u7ed3\u679c\u663e\u793a\uff0cCDK2\u86cb\u767d\u6c34\u5e73\u968f\u9a6c\u94b1\u82f7\u5143\u6d53\u5ea6\u5347\u9ad8\u663e\u8457\u4e0b\u964d(P < 0.01)\uff0cCo-IP\u8bc1\u5b9eCDK2\u4e0eKLHL6\u7684\u76f8\u4e92\u4f5c\u7528\u589e\u5f3a\u3002\u5409\u59c6\u8428\u67d3\u8272\u793a\u9ad8\u6d53\u5ea6\u7ec4(480 \u03bcmol/L)\u7ec6\u80de\u51fa\u73b0\u591a\u6838\u3001\u6838\u788e\u88c2\u7b49\u67d3\u8272\u4f53\u4e0d\u7a33\u5b9a\u6027\u7279\u5f81\uff1bNBT\u5b9e\u9a8c\u8868\u660e\u6c27\u5316\u5e94\u6fc0\u6c34\u5e73\u663e\u8457\u5347\u9ad8(480 \u03bcmol/L\u7ec4OD560\u503c\u8fbe\u5cf0\u503c\uff0cP < 0.01)\uff0c\u4f34\u968fPRDX2\u8868\u8fbe\u4e0b\u8c03\u4e0eMAFB\u8868\u8fbe\u4e0a\u8c03\uff1b\u4f53\u5185\u5b9e\u9a8c\u663e\u793a\uff0c\u9a6c\u94b1\u82f7\u5143\u6cbb\u7597\u7ec4\u5c0f\u9f20\u9aa8\u9ad3hCD45+AML\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e(P < 0.05)\uff0cCD11b+\u5206\u5316\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8(P < 0.05)\uff0c\u813e\u810f\u80bf\u5927\u7a0b\u5ea6\u51cf\u8f7b\u3002. \u9a6c\u94b1\u82f7\u5143\u901a\u8fc7\u964d\u89e3CDK2\u534f\u540c\u8bf1\u5bfc\u6c27\u5316\u5e94\u6fc0\u4e0e\u57fa\u56e0\u7ec4\u4e0d\u7a33\u5b9a\u6027\u589e\u52a0\uff0c\u4fc3\u8fdbAML\u7ec6\u80de\u5206\u5316\uff0c\u4e3aAML\u6cbb\u7597\u63d0\u4f9b\u601d\u8def\u3002.\n\nID: 42186564\nTitle: Dual roles of two Tfdps in germline nuclear meiosis and somatic nuclear fragmentation during sexual reproduction in the unicellular organism Paramecium tetraurelia.\nAbstract: Meiosis is regulated by phase-specific genes to orchestrate nuclear and cytoskeletal dynamics essential for sexual reproduction. The ciliate Paramecium tetraurelia exhibits nuclear dimorphism, harboring two germline micronuclei (MICs) and one somatic macronucleus (MAC) within a single cell during vegetative growth. During sexual reproduction, the MICs undergo meiosis and the MAC deforms and fragments, providing a unique model to study the regulation of diverse nuclear events. Transcription factor DP (TFDP), which heterodimerizes with E2Fs, can bind to specific DNA motifs in promoters of cell cycle-regulated genes to activate or repress their expression. Here, we identified 16 TFDP homologs in P. tetraurelia, representing an exceptional gene family expansion accompanied by functional domain diversification. The functions of Tfdp1a and Tfdp1b, which are specifically expressed during sexual reproduction and localize in the old and new MACs, were further investigated. Their depletion resulted in meiotic arrest at metaphase in the MIC, failure of old MAC fragmentation, and abortive cytokinesis. Transcriptomic analysis revealed that TFDP1A/1B knockdown primarily causes gene downregulation, with\u2009>\u200960% of downregulated genes being specifically highly expressed during sexual reproduction. Functional annotation and enrichment analyses demonstrated significant downregulation of proteins involved in meiosis, DNA replication, and DNA repair. Critically, multiple downregulated meiotic regulators are essential for proper homologous chromosome segregation and sister chromatid separation, providing a mechanistic basis for the observed MIC meiotic arrest. This study uncovers Tfdp1a/1b as essential regulators of the distinctive meiotic process in P. tetraurelia, providing crucial insights into nuclear dynamics and the regulation of sexual reproduction in binucleate systems.

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: 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: 42136278\nTitle: Therapeutic Insights into Natural Products for Modulating Neurodegenerative Disease Pathways.\nAbstract: Neurodegenerative Disorders (NDs), such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and Amyotrophic Lateral Sclerosis (ALS), are chronic and progressive conditions marked by the gradual loss of neuronal structure and function. These disorders lead to cognitive, motor, and sensory decline, significantly reducing quality of life and posing a major global health burden due to rising healthcare costs and the absence of curative therapies. This review aims to comprehensively explore the therapeutic potential of natural products in targeting cellular and molecular mechanisms underlying NDs, highlighting their neuroprotective roles and potential for disease modification. A comprehensive literature review was conducted using databases including PubMed, Scopus, Web of Science, and Google Scholar. Peer-reviewed articles, clinical trials, and experimental studies were analyzed to evaluate the therapeutic potential of natural products and their bioactive compounds in the management of NDs. ND pathogenesis involves oxidative stress, neuroinflammation, mitochondrial dysfunction, and abnormal protein aggregation, ultimately leading to neuronal death. Current therapies largely provide symptomatic relief without altering disease progression. Natural products from plants, fungi, and marine sources demonstrate strong neuroprotective potential through multitargeted mechanisms. Bioactive compounds such as flavonoids, alkaloids, terpenoids, and polyphenols exhibit antioxidant, anti-inflammatory, anti-apoptotic, and neuroprotective activities. Key molecules, including curcumin, resveratrol, luteolin, quercetin, and catechins, modulate signaling pathways such as NF-\u03baB, MAPK, PI3K/AKT, Nrf2, apoptosis, and autophagy, thereby reducing amyloid-beta aggregation, protecting dopaminergic neurons, improving mitochondrial function, and enhancing cognition in preclinical and clinical studies. Natural products represent promising candidates for disease modification in NDs due to their multi-pathway actions and relatively low toxicity. However, major limitations, such as poor bioavailability, pharmacokinetic variability, and the lack of standardized formulations, hinder clinical translation. Innovative strategies, including advanced drug-delivery systems, structural modifications, and synergistic formulations, are needed to overcome these barriers. Natural products hold significant therapeutic potential in managing neurodegenerative diseases by targeting multiple pathological mechanisms. Their integration into ND treatment could provide safer and more effective alternatives, but further well-designed clinical trials are essential to establish their efficacy and facilitate clinical application.\n\nID: 42126665\nTitle: Howell-jolly body-like inclusions in multiple leukocyte lineages: an underrecognized morphologic feature in a case of severe sepsis.\nAbstract: Howell-Jolly body-like inclusions (HJBLI) are most commonly observed in myelodysplastic syndromes, viral infections, or during immunosuppressive therapy. They predominantly appear in neutrophils, with occurrence across multiple leukocyte lineages being uncommon. We report a rare case of multilineage HJBLI in a patient with severe sepsis, describe the associated morphological features, and discuss the clinical relevance to prevent misinterpretation in routine practice. We present the case of a 23-year-old female patient with incomplete abortion complicated by severe\u00a0Escherichia coli sepsis, corroborated by positive blood and vaginal cultures alongside markedly elevated procalcitonin and C-reactive protein levels. Peripheral blood smears (\u00d71000 magnification) revealed round, densely basophilic inclusions morphologically consistent with HJBLI in neutrophils, eosinophils, and monocytes, with up to five inclusions per monocyte. Concomitant toxic changes, including prominent toxic granulation, D\u00f6hle bodies, and cytoplasmic vacuolization, were evident. Multilineage HJBLI can be detected in the setting of severe sepsis, likely resulting from sepsis-induced nuclear fragmentation and dyspoiesis. This expands HJBLI's disease spectrum; familiarity with this morphology improves accurate recognition in routine hematological examinations.\n\nID: 42110700\nTitle: A new class of indole-based HDAC8 inhibitors as potential anti-lung cancer agents: in silico design, synthesis, biological assessment and binding interaction analysis.\nAbstract: A novel series of indole-based hydroxamic acids was designed, synthesized, and evaluated as promising HDAC8 inhibitors for lung cancer therapy. In silico analyses, including classification-based QSAR, chemical space networks, and scaffold diversity analysis on 2078 HDAC8 inhibitors uncovered essential molecular features for strong HDAC8 potency, informing the design of 12 derivatives. Docking studies ranked the top two candidates, which were subsequently derivatized, synthesized and evaluated through HDAC8 enzymatic and cytotoxicity assays. Several compounds proved highly active, with 6c exhibiting superior HDAC8 inhibition, strong antiproliferative activity against A549 cells, and minimal impact on HEK-293 normal cells. Mechanistic studies demonstrated apoptosis induction, G2/M arrest, ROS generation, and increased nuclear fragmentation. Western blot analysis confirmed intracellular HDAC8 inhibition through elevated SMC3 acetylation, while 500 ns molecular dynamics simulations supported stable binding of 6c within the HDAC8 active site. Collectively, these findings identify compound 6c as a promising HDAC8 inhibitor and potential lead candidate for the development of novel anti-lung cancer agents targeting epigenetic pathways. This work provides insights that might advance efforts to develop effective non-platinum anticancer agents.\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: 42097486\nTitle: Conjecture for a free radical epimerization process in Alzheimer, Parkinson, Lewy body, amyotrophic lateral sclerosis, progressive Supranuclear Palsy and Creutzfeldt Jakob diseases.\nAbstract: Brain protease-resistant misfolded proteins have been described in Alzheimer (AD), Parkinson (PD), Lewy Body (LBD), Amyotrophic Lateral Sclerosis (ALS), Progressive Supranuclear Palsy (PSP) and Creutzfeldt Jakob (CJD) diseases. The role of free radicals in generating these protease resistant structures has been experimentally demonstrated in prion bovine spongiform encephalopathy (BSE), when manganese is substituted for copper (Cu), in bovine brain homogenates in reductive medium, while Cu protective effect against free radicals can be restored by Cu supplementation in oxidative medium. These facts can suggest a free radical-induced epimerization process in neuroprotein misfolding leading to the transformation of physiological L-amino acid brain proteins into abnormal D-structures which will be deposited in the brain as observed in neurodegenerative diseased brains. A blood Cu increase, not ceruloplasmin (CP) bound correlated with a Cu increase in the cerebrospinal fluid (CSF) and a Cu decrease in the brain have been described in AD, PD, ALS, or CJD. This indicates that following neuronal death, Cu might be expelled from brain proteins and subsequent to redistribution between brain, CSF and blood, it will result a brain Cu deficiency and a decrease in Cu brain protection against free radicals. In the aim of repairing this deficiency and slow down the neurodegenerative disease process, a brain Cu complexes vectorization through the blood-brain barrier might restore brain Cu homeostasis.\n\nID: 42086533\nTitle: Proteasomal-dependent CHK1 degradation leads to DNA damage accumulation in ALS cellular model systems.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterised by the aggregation of TDP-43 and mutant FUS in the cytoplasm of affected motor neurons. Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates.\n\nID: 42072687\nTitle: Transcriptomic Analysis Reveals the Beneficial Effects of Spermidine in an ALS Mouse Model.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease marked by progressive degeneration of motor neurons and skeletal muscle. Gene expression analysis of the spinal cord and gastrocnemius of the SOD1-G93A ALS mouse model revealed a strong increase in inflammatory pathways and, specifically in the ALS gastrocnemius, a decrease in mitochondrial transcription and an increase in ribosomal protein expression. Treatment of ALS mice with the polyamine spermidine (SPD), a promising molecule in combating neurodegeneration and muscle atrophy, is able to partially restore the expression of more than four thousand genes in gastrocnemius tissue, including the mitochondrial regulator Pgc1\u03b1, as well as all the mitochondrial encoded genes and a large class of ribosomal proteins. SPD enhanced mitochondrial bioenergetics, as evidenced by Seahorse experiments, and delayed muscle weakness in vivo, as shown by grip strength records. These findings suggest that SPD can act as a potential supplement in the therapeutic strategy for ALS, offering a foundation for further research to improve patient outcomes.\n\nID: 42070160\nTitle: miRNAs in Amyotrophic Lateral Sclerosis: Tiny Molecules, Tremendous Impact.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder distinguished by progressive motor neuron degeneration, with diverse clinical manifestations and complex genetic and environmental triggers. The variability in disease progression underscores the necessity for tailored diagnostic and therapeutic approaches. MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression, have emerged as promising biomarkers and therapeutic targets in ALS. Dysregulation of specific miRNAs has been linked to mechanisms of ALS, including neuromuscular dysfunction, neuroinflammation, and neuronal survival/apoptosis. The potential of miRNA-based therapies, such as mimics and inhibitors, offers a more integrated approach by modulating entire disease networks, rather than targeting isolated pathways. However, challenges persist, particularly in delivering these therapies efficiently across the blood-brain barrier and minimizing off-target effects. Current delivery strategies involving nanoparticles, viral vectors, and exosome-based approaches require optimization for clinical use. This review synthesizes the latest research on miRNA-mediated mechanisms in ALS, evaluating their diagnostic, prognostic, and therapeutic potential, while highlighting the current limitations in clinical validation. It underscores the importance of standardized methodologies, multi-omics integration, and rigorous validation to facilitate the clinical translation of miRNA-based strategies. Standardized protocols and multicenter validation in large cohorts are essential to confirm the diagnostic accuracy of miRNAs, paving the way for their clinical application in ALS precision medicine.\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: 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: 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: 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: 42148083\nTitle: Ferroptosis-immune crosstalk in CNS diseases: mechanisms and translational insights.\nAbstract: Ferroptosis is a form of regulated cell death driven by iron-dependent lipid peroxidation, which plays a pivotal role in regulating the inflammatory-immune microenvironment of central nervous system (CNS) diseases. Mounting evidence indicates that dysregulated iron metabolism and an imbalance in antioxidant defenses can induce ferroptosis in neurons and glial cells while simultaneously remodeling immune cell function, thereby establishing a bidirectional feedback loop that amplifies neuroinflammation and tissue damage. In neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), pro-inflammatory cytokines such as TNF-\u03b1 and IL-1\u03b2 released by activated microglia upregulate neuronal iron transporters (e.g., DMT1 and TfR1), promoting iron accumulation and ferroptotic cell death. In turn, damage-associated molecular patterns released from ferroptotic cells further potentiate immune activation, forming a self-amplifying cycle. In contrast, within the glioma microenvironment, CD8+ T cell-derived IFN-\u03b3 suppresses SLC7A11 expression in tumor cells, leading to glutathione depletion and glutathione peroxidase 4 inactivation, thereby triggering ferroptosis and modulating anti-tumor immunity. Although targeting ferroptosis or neuroimmune pathways has shown therapeutic promise in mitigating neurological deficits and enhancing anti-tumor responses, the underlying mechanisms governing ferroptosis-immune crosstalk remain inadequately characterized. Herein, this review systematically summarizes the key biological characteristics of ferroptosis and immune responses, with particular emphasis on their interplay across major CNS disorders (i.e., AD, PD, ALS, multiple sclerosis, stroke, and glioma). Furthermore, we discuss emerging therapeutic strategies encompassing small molecules, immunomodulatory approaches, and nanotechnology-based interventions, highlighting the ferroptosis-immune axis as a promising therapeutic target for CNS diseases.\n\nID: 42123994\nTitle: Long-Chain Fatty Acids as Drivers of Neuroinflammation in Neurodegeneration: Mechanistic Links to Lipid Peroxidation, Ferroptosis, and Mitochondrial Dysfunction.\nAbstract: Background: Neurodegenerative diseases (NDs) are mainly considered disorders marked by severe immunometabolic imbalance, characterized by ongoing neuroinflammation and glial activation. While mitochondrial dysfunction and oxidative stress are well-known features, the upstream metabolic factors linking these pathological processes remain poorly understood. Methods: In this review, we examined recent preclinical and clinical studies exploring the connections between lipid metabolism, glial immunometabolism, and regulated cell death pathways. Our focus was on how long-chain fatty acids (LCFAs) facilitate communication among mitochondria, reactive oxygen species (ROS), and ferroptosis in Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). Results: New evidence shifts LCFAs from merely being passive indicators of cellular damage to active, upstream regulators of the neuroimmune response. Existing research shows that excess LCFA intake can overload astrocytic mitochondrial oxidative phosphorylation, leading to abnormal lipid droplet buildup and reactive astrogliosis. This lipid-driven reactivity promotes microglial polarization toward a persistent pro-inflammatory state. Notably, high levels of specific LCFAs, especially arachidonic acid, increase ROS production and lipid peroxidation. This lipotoxic environment ultimately triggers ferroptosis, an iron-dependent form of cell death shared across multiple NDs. Conclusions: The harmful interaction among mitochondrial dysfunction, lipid peroxidation, and ferroptosis is driven by an imbalance in LCFA levels. Addressing current challenges, such as the complex effects of polyunsaturated fatty acid supplementation, requires advanced techniques like single-cell multi-omics and artificial intelligence. Understanding this intricate lipidomic-transcriptomic crosstalk is crucial for moving toward personalized neuroimmunometabolism and developing new treatments to prevent ferroptosis.\n\nID: 42092406\nTitle: TRIM16 attenuates TDP43-mediated oxidative injury by coordinating Nrf2 activation and TFR1 autophagic degradation.\nAbstract: TAR DNA-binding protein 43 (TDP43) aggregation is a well-established pathological hallmark of amyotrophic lateral sclerosis (ALS) and related neurodegenerative disorders, contributing significantly to oxidative stress and neuronal injury. Here, we report that the M337V mutation in TDP43 exacerbates its proteotoxicity relative to the wild-type protein. Concurrently, multi-omics analysis revealed a pronounced downregulation of TRIM16 in motor neuron-like cells expressing either wild-type or M337V mutant TDP43. Functional studies demonstrated that TRIM16 overexpression effectively mitigated oxidative stress, restored mitochondrial integrity, and suppressed ferroptosis. Mechanistically, TRIM16 promoted the ubiquitination and degradation of Keap1, thereby facilitating the activation of Nrf2-mediated antioxidant genes. Furthermore, we identified the iron import receptor TFR1 as a novel ubiquitination substrate of TRIM16. TRIM16 mediated the ubiquitination of TFR1 and targeted it for p62-dependent autophagic degradation, which in turn reduced iron accumulation and lipid peroxidation. Collectively, our findings establish TRIM16 as a pivotal suppressor of TDP43-induced toxicity by orchestrating dual cytoprotective pathways to enhance cellular resilience, highlighting its promising therapeutic potential for TDP43 proteinopathy.\n\nID: 42085907\nTitle: Bmal1 regulates hippocampal oxidative damage in cognitive memory impairment induced by artificial light at night in mice.\nAbstract: Artificial light at night (ALAN) has emerged as a significant public health concern, yet its effects on cognitive impairment remain poorly understood. This study investigated the impact of 28 consecutive days of 5-lx ALAN exposure on hippocampal function in C57BL/6\u00a0J mice. We evaluated locomotor behavior, neuronal morphology, neurogenesis, oxidative stress, and circadian rhythms, revealing that ALAN induces cognitive impairment. ALAN exposure reduced Bmal1 expression, increased reactive oxygen species (ROS) and malondialdehyde accumulation, and disrupted the time-of-day-dependent differences expression of NRF2, SOD1, and GPX1. These alterations suppressed SOD and GPX enzymatic activity, leading to hippocampal oxidative damage. To clarify BMAL1's role, we used adeno-associated virus (AAV) to modulate Bmal1 expression in the hippocampus. ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression. These findings suggest that ALAN can contribute to memory impairment by disrupting hippocampal damage and impairing neurogenesis through its effect on Bmal1. This study identifies potential molecular targets for preventing and treating cognitive impairment and neurodegenerative disorders.\n\nID: 42074133\nTitle: Pridopidine Protects ALS Patient-Derived Neural Progenitor Cells via Sigma-1 Receptor Activation.\nAbstract: The sigma-1 receptor (S1R) is an endoplasmic reticulum (ER)-resident protein enriched at the mitochondria-associated ER membranes (MAMs) that supports ER homeostasis, preserves mitochondrial function, and enhances cell survival under stress. Disruptions of MAM integrity and prolonged ER stress are well-recognized pathological features of amyotrophic lateral sclerosis (ALS), contributing to motor neuron dysfunction and degeneration. In this study, we evaluated the protective effects of pridopidine, a highly selective and potent S1R agonist currently in clinical development for Huntington's disease (HD) and ALS, using neural progenitor cells (NPCs) derived from induced pluripotent stem cells (iPSCs) from a patient with sporadic ALS. Exposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted mitochondrial membrane potential, upregulated expression of the mitochondrial apoptotic marker, BAX, increased caspase-3 activation, and reduced cell viability. Pridopidine significantly attenuated tunicamycin-induced BiP and CHOP expression in a biphasic, dose-dependent manner (with maximal efficacy at 1 \u00b5M), consistent with the typical pharmacology of S1R agonists. Pridopidine restored mitochondrial membrane potential, reduced mitochondrial apoptotic signaling, shown by decreased BAX expression and caspase-3 activation, and improved survival of ALS-NPCs under ER stress. Co-treatment with the selective S1R antagonist, NE-100, attenuated these effects, supporting an S1R-mediated mechanism of action for pridopidine. Together, these results demonstrate that S1R activation by pridopidine mitigates ER-stress-induced mitochondrial dysfunction and cell loss in ALS-NPCs, resulting in enhanced survival of NPCs supporting the therapeutic potential of pridopidine in ALS.\n\nID: 42073997\nTitle: Impact of Oxidative Stress-Driven Ferroptosis in Neurodegeneration.\nAbstract: Ferroptosis is an iron-dependent cell death driven by lipid peroxidation and failure of cellular antioxidant defenses. It is triggered by oxidative stress and can be aggravated by aging, inflammation, and dysregulation of iron homeostasis. In the central nervous system, iron dyshomeostasis, mitochondrial dysfunction, and membrane lipid remodeling can amplify oxidative injury and increase susceptibility to ferroptotic damage, particularly in vulnerable neurons. There is growing evidence that ferroptosis-related processes are linked to Alzheimer's disease, Parkinson's disease, Huntington's disease, and Amyotrophic Lateral Sclerosis. This review addresses novel approaches to track ferroptosis in vivo, such as imaging and biomarker techniques, and important molecular mechanisms linking iron metabolism, reactive oxygen species, and PUFA-driven lipid peroxidation to neuronal damage. We also explore upstream transcriptional control via NRF2, iron chelation and iron-handling modulation, inhibition of lipid peroxidation, and reinforcement of the System Xc-GSH-GPX4 and CoQ10-linked defense pathways. Subsequently, we highlight translational issues that need attention to further progress ferroptosis-targeted therapies for neurodegenerative disease.\n\nID: 42054746\nTitle: From necroptosis to neuroinflammation: Unraveling mechanisms and therapeutic targets in age-related cognitive decline.\nAbstract: Aging is the major risk factor for several chronic conditions, including cognitive decline and dementia. It is accompanied by profound immune alterations characterized by a progressive decline in immune competence, a process known as immunosenescence. The resulting dysregulation of immune function leads to the overproduction of proinflammatory cytokines and fuels a persistent, low-grade inflammatory state termed inflammaging. This chronic inflammation contributes to dysfunction across the central and peripheral nervous systems, promoting neuronal damage and accelerating neurodegenerative processes such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and other age-related cognitive disorders. Within this framework, prolonged activation of inflammatory pathways can trigger regulated forms of cell death. Among these, necroptosis has recently emerged as a potential mediator linking inflammaging to neurodegeneration. Its core molecular effectors, including the receptor-interacting protein kinases RIPK1 and RIPK3 and the mixed-lineage kinase domain-like protein (MLKL), are increasingly expressed in aged neural tissues, promoting the release of damage-associated molecular patterns (DAMPs) that amplify glial activation, oxidative stress, and blood-brain barrier disruption. Growing evidence suggests that necroptotic signaling may be upregulated in the aging brain and in neurodegenerative disorders, where it could contribute to neuronal loss and cognitive impairment. This review discusses the potential role of necroptosis in the continuum between inflammation and neurodegeneration, highlighting emerging diagnostic and therapeutic perspectives. Epigenetic and circulating biomarkers, such as phosphorylated MLKL and specific microRNAs, may support early detection, while pharmacological and nutraceutical strategies targeting necroptosis show promising neuroprotective effects in preclinical studies.\n\nID: 42031063\nTitle: Disulfidptosis in neurodegenerative diseases: From redox imbalance to neuronal dysfunction.\nAbstract: Disulfidptosis is a recently identified form of regulated cell death driven by disulfide stress and cytoskeletal collapse under conditions of impaired reducing capacity. Neurodegenerative diseases (NDs), including Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis, are characterized by oxidative stress, mitochondrial dysfunction, metabolic impairment, protein aggregation, and cytoskeletal instability-features that may provide a permissive intracellular context for disulfidptosis. However, its occurrence and pathological relevance in these disorders remain incompletely understood. In this review, we examine the potential involvement of disulfidptosis in neurodegenerative diseases from a disease-centered perspective. We emphasize that current evidence is largely indirect and based on mechanistic overlap rather than direct experimental validation in neural systems. Accordingly, we distinguish between direct evidence, indirect mechanistic support, and pathophysiological plausibility. We further discuss cell-type-specific susceptibility across neurons and glial cells, analyze its relationship with other cell death pathways, and consider potential therapeutic implications. Overall, disulfidptosis is best regarded as a context-dependent and emerging mechanism that may contribute to neuronal vulnerability under specific metabolic and redox constraints. Clarifying its disease relevance will be essential for determining its significance in neurodegeneration and its potential as a therapeutic target.\n\nID: 41968900\nTitle: Selective Radioprotection by the Fusion Antioxidant Enzyme GS1XR Via an MMP-2/9-Cleavable Cell-Penetrating Switch.\nAbstract: Radiotherapy is central to cancer treatment but radiation-induced oxidative stress also damages normal tissues. To achieve selective radioprotection of normal tissues, we systematically evaluated, in\u00a0vitro and in\u00a0vivo, the antioxidant and radioprotective performance of a previously engineered fusion antioxidant enzyme, GS1XR (GST-SOD1-X-R9). GS1XR efficiently enters normal cells in low matrix metalloproteinases (MMP)-2/9 environments, scavenges radiation-induced reactive oxygen species (ROS), maintains the Nrf2 antioxidant pathway, suppresses apoptosis, and increases clonogenic survival. In contrast, in 3D tumor microenvironments with high MMP-2/9, cleavage of the X peptide removes R9, resulting in a loss of transmembrane capacity and a pronounced reduction in intracellular ROS scavenging. Animal studies further showed that GS1XR significantly alleviates whole-body irradiation-induced hematopoietic injury and, in tumor-bearing models receiving radiotherapy, does not compromise radiotherapy-mediated tumor control. Collectively, GS1XR couples microenvironment-responsive cell entry with enzymatic antioxidation to achieve selective radioprotection while preserving radiotherapy-mediated tumor control.\n\nID: 41962408\nTitle: Tanshinone IIA alleviates ferroptosis and oxidative injury in chronic experimental colitis through Nrf2 activation.\nAbstract: This study aims to explore the mechanism by which Tanshinone IIA (Tan IIA) inhibits ferroptosis and oxidative injury in TNBS-induced Inflammatory Bowel Disease (IBD) in mice. Experimental colitis was induced by the rectal administration of 2,4,6-Trinitrobenzenesulfonic acid (TNBS). Primary intestinal cells, luciferase reporter assay and nuclear factor erythroid 2-related factor 2(Nrf2)-null mice were used to clarify if Tan IIA ameliorates ferroptosis and oxidative injury in TNBS-induced colitis dependent on Nrf2. Tan IIA (20\u202fmg/kg) ameliorated colonic weight/length ratio, pathological scores and fibrosis in TNBS-induced mice. Moreover, Tan IIA reduced pro-inflammatory factors and increased the expression of tight junction proteins, likely contributing to the improvement of colonic barrier integrity. Tan IIA significantly induced the expression of Nrf2 target genes in primary intestinal epithelial cells and activated Nrf2 luciferase reporter activities in HCT116\u202fcells. In TNBS-induced wild-type mice but not in Nrf2-null mice, Tan IIA significantly improved ferroptosis and oxidative injury as revealed by decreased ferritin light chain (FTL) level and upregulated Nrf2 downstream genes heme oxygenase-1 (HO-1) and superoxide dismutase 1 (SOD1) expression. In conclusion, Tan IIA significantly alleviates colonic ferroptosis and oxidative injury induced by TNBS in mice through modulation of the Nrf2 signaling.\n\nID: 41922126\nTitle: The neuroprotective role of eugenol against glyphosate-induced toxicity in rats: Modulation of oxidative stress, inflammation, ER stress and apoptotic signaling pathways.\nAbstract: Glyphosate (GLY) is a widely used herbicide, particularly in agriculture, and its residues in plants and soil can induce toxic effects in various organisms, including humans, with the brain being especially vulnerable. Eugenol (EU), a natural antioxidant found in cloves, has demonstrated protective effects against different toxic substances. This experimental study explored whether eugenol could mitigate neurological damage triggered by glyphosate exposure in rats. A total of forty male Sprague-Dawley rats were allocated into five experimental groups consisting of control, eugenol (100\u202fmg/kg), glyphosate (150\u202fmg/kg), EU50 combined with glyphosate (50\u202fmg/kg + 150\u202fmg/kg), and EU100 combined with glyphosate (100\u202fmg/kg + 150\u202fmg/kg). Animals received the respective treatments by oral gavage for a period of seven days. Motor and anxiety-related behaviors were evaluated using behaviour tests, after which brain tissues were processed for histopathological analysis. Biochemical analyses included ELISA assessment of oxidative stress markers (MDA, SOD1, GSH, and GPx1), RT-PCR analysis of endoplasmic reticulum (ER) stress- and apoptosis-related genes (GRP78, ATF4, CHOP, PI3K/AKT/mTOR, BAX, and Bcl-2), Western blot evaluation of inflammatory and antioxidant signaling pathways (TLR4/NF-\u03baB and Nrf2/HO-1/SIRT1), and immunohistochemical and immunofluorescence analyses of neuroplasticity, circadian rhythm, and autophagy markers (BDNF, BMAL1, CLOCK, Beclin-1, and LC3A/B). GLY exposure significantly increased lipid peroxidation (MDA), ER stress markers (GRP78 and CHOP), pro-inflammatory mediators (TLR4, NF-\u03baB, TNF-\u03b1, and IL-1\u03b2), apoptotic signaling (BAX and caspase-3), and autophagy-related proteins, while suppressing antioxidant pathway components. Glyphosate exposure induced behavioral impairments accompanied by increased oxidative stress, inflammatory activation, endoplasmic reticulum stress, apoptosis, and dysregulated autophagy in cerebral cortex tissue. EU treatment dose-dependently attenuated these molecular and histopathological alterations, restored antioxidant and cellular stress responses, and significantly improved behavioral performance, indicating a protective role against GLY-induced neurotoxicity. Overall, EU may represent a promising therapeutic candidate for mitigating herbicide-induced brain injury.\n\nID: 41905503\nTitle: Intranasal rosmarinic acid reduces cognitive and hippocampal damage from repeated neonatal isoflurane exposure by regulating apoptotic/oxidative/inflammatory responses, and heat-shock and 14-3-3 proteins.\nAbstract: Repeated or prolonged exposure to general anesthetics like isoflurane (ISO) during neurodevelopment can lead to long-term neurocognitive and behavioral deficits, particularly because pediatric brains lack adequate antioxidant defenses, and no preventive therapies currently exist. Rosmarinic acid (RA), a polyphenolic compound with antioxidant and neuroprotective properties, has not yet been evaluated for mitigating ISO-induced toxicity. In this study, Wistar albino rat pups were exposed to ISO (1.5% in 30% oxygen/air, 3-h) on postnatal days (P)7\u202f+P9\u202f+\u202fP11, and the protective effects of intranasal RA (25\u202fmg/kg) pretreatment (1-h before anesthesia) were investigated for the first time. Control groups received either oxygen alone or RA before oxygen exposure. On P12, hippocampal tissue was examined for detecting acute neuronal apoptosis, oxidative stress, inflammation, and stress-related proteins using histopathology and immunoblotting. Cognitive performance was assessed using Morris Water Maze tests that evaluated spatial learning (P28-P32) and both short- and long-term memory (P33, P60, P90). Repeated ISO exposure impaired learning and memory, increased anxiety-like behaviors, and caused hippocampal damage, along with elevated pro-apoptotic markers (Bax/Bcl-2 ratio, cleaved caspase-3, PARP1 fragments), redox imbalance and inflammation (reduced SOD1; increased GPX1, 4HNE, NF-\u03baB-p65, TNF-\u03b1). ISO also disrupted stress signaling by reducing p-HSF1, Hsp90, and Hsp60 levels, while raising Hsp70 and decreasing 14-3-3 isoforms. RA pretreatment countered these effects by restoring antioxidant and stress-response proteins, reducing inflammation and apoptosis, and maintaining neuronal integrity and cognitive function. No harmful effects were observed in the RA-only group. These findings suggest that intranasal RA pretreatment may be a preventive strategy against anesthesia-related neurotoxicity in pediatric patients.\n\nID: 41903067\nTitle: HSP90 inhibition potentiates oxidant-based antimelanoma action of novel thioquercetin derivatives by compromising AhR/CYP1A1 pathway.\nAbstract: Quercetin, a plant-derived dietary flavonoid, has multifunctional biological activities, including anticancer action; however, its applications may be restricted due to limited bioavailability. Thus, novel synthetic quercetin derivatives (QDs) with improved properties and/or drug combinations should be designed and tested. In the present study, anticancer activity of fourteen newly synthesized QDs was investigated using four cellular models of melanoma, namely A375, MM370, G-361, and SH-4 cells. Thioquercetins (thioQ, thioQ(OAc)4, and thioQ(OAc)5), when used at low micromolar range, induced apoptotic cell death in melanoma cells compared to normal cells. Thioquercetins also reduced the population of spheroid-forming cells and suppressed the growth of A375 cells in 3D spheroid models. Thioquercetin-mediated antimelanoma action was potentiated upon heat shock protein 90 (HSP90) inhibition. Co-treatment with the HSP90 inhibitor 17-DMAG and thioquercetins augmented oxidative stress (increased superoxide production, decreased levels of antioxidant proteins SOD1, and PRDX1-2), and impaired the aryl hydrocarbon receptor (AhR)/cytochrome P450 1A1 (CYP1A1) signaling pathway-based detoxification of thioquercetins by the inhibition of AhR translocation to the nucleus and AhR-mediated stimulation of CYP1A1 expression leading to enhanced cytotoxic effects against melanoma cells. The senolytic activity of thioQ(OAc)4 with four acetylated hydroxy groups against cisplatin-induced senescent melanoma cells was also revealed in selected experimental settings. We suggest that the use of novel thioquercetin-based derivatives along with HSP90 inhibitors should be further validated in vivo and considered for the design of more effective antimelanoma strategies in the future.\n\nID: 41894255\nTitle: Destabilized Soluble SOD1 Species as Potential Determinants of Disease Severity in Familial Amyotrophic Lateral Sclerosis.\nAbstract: Mutations in the Cu/Zn superoxide dismutase (SOD1) gene are linked to familial amyotrophic lateral sclerosis (ALS), yet the identity of the toxic molecular species remains unclear. We investigated the relationship between protein misfolding and pathogenicity by expressing GFP-tagged wild-type and mutant SOD1 (A4V, H46R, G93A) in mouse hippocampal HT22 cells. Western blotting under nonreducing conditions suggested that A4V, associated with rapid disease progression, was largely depleted of properly folded soluble SOD1 and instead produced highly destabilized soluble species. In contrast, H46R, associated with a milder phenotype, showed a moderate reduction in properly folded soluble SOD1 and generated partially folded/native-like conformers. G93A exhibited biochemical characteristics intermediate between those of A4V and H46R. A4V also showed a pronounced loss of GFP fluorescence, indicating severe structural destabilization; the extent of fluorescence loss in A4V, G93A, and H46R broadly correlated with clinical severity. Neither CuATSM nor ebselen\u2500targeting metal binding and disulfide formation, respectively\u2500rescued fluorescence, suggesting broader defects in SOD1 maturation. Nevertheless, both compounds inhibited ferroptosis, a nonapoptotic form of cell death characterized by iron-dependent lipid peroxidation, in HT22 cells, indicating alternative neuroprotective mechanisms. These findings identify destabilized soluble SOD1 species as a key toxic entity in ALS and highlight the utility of GFP-tagged constructs for evaluating folding status and screening therapeutic candidates.\n\nID: 41870605\nTitle: CILP Inhibits hyaline cartilage fibrosis and chondrocyte ferroptosis via keap1-Nrf2 axis in early osteoarthritis exercise therapy.\nAbstract: BACKGROUND: By analyzing the single-cell RNA-Seq libraries we established of OA joints during exercise therapy, we found cartilage intermediate zone might participate in early OA exercise therapy. METHODS: Early OA rat model was established by 4-week anterior cruciate ligament transection (ACLT). The radiomics was used to evaluate the relative damaged and undamaged area in OA patients\u2019 cartilage. We overexpressed and knocked down CILP in early OA chondrocyte to explore its potential mechanism. The quantitative proteomics was used to examine the protein profiles of the CILP-treated chondorcyte. The Yeast One-Hybrid Assay, Co-Immunoprecipitation (Co-IP), Nrf2 cytosol-nuclei fractionation and ubiquitination assay were used to investigate the potential mechanism in CILP intervention. Western blot, ROS, JC-1, Ferrous ion, MDA and GSH detection, transmission electron microscopy (TEM) were used to explored the therapeutic effect of CILP on OA. RESULTS: Moderate exercise up-regulates CILP in the articular cartilage intermediate zone. CILP recovers the ratio of type II / I collagen, Sox9, \u03b1-SMA expression and competitively bind to Keap1 protein and reduce the stability of Keap1-Nrf2 dimer, thereby reducing the degree of Nrf2 ubiquitination and promoting Nrf2 nuclear translocation. Nrf2 nuclear translocation activated SLC7A11, HO-1, GPX4 and SOD-1 expression, then decreased the MDA contents, but increased GSH content, which ultimately inhibited chondrocytes ferroptosis and promoted hyalinization of fibrocartilage. CONCLUSION: Exercise induced cartilage intermediate zone and CILP-Keap1-Nrf2 axis inhibits hyaline cartilage fibrosis and chondrocyte ferroptosis to alleviate early osteoarthritis.\n\nID: 41861196\nTitle: Mitochondrial dysfunction and programmed cell death in Alzheimer's disease: A retrospective bioinformatics study.\nAbstract: Alzheimer's disease (AD) is a major cause of dementia, and this paper explores the unclear roles of mitochondrial dysfunction and programmed cell death in AD. Differentially expressed genes (DEGs) were identified using AD datasets GSE63061 and GSE63060 from the Gene Expression Omnibus. DEGs were intersected with mitochondria-related genes and programmed cell death-related genes to obtain DEGs (in AD) intersected with mitochondrial-related genes and DEGs (in AD) intersected with programmed cell death-related genes. Correlation analysis of these DEGs was used to identify candidate genes. Machine learning algorithms were applied to key genes, followed by functional enrichment, network construction, immune infiltration analysis, drug prediction, and expression validation. Two key genes, superoxide dismutase 1 (SOD1) and translocase of the outer mitochondrial membrane 7 (TOMM7), were identified and linked to pathways like ribosome and chemokine signaling. A strong positive correlation (0.76, P\u2005<\u2005.001) was found between them. Immune analysis showed differences in 11 immune cells between AD and controls, with TOMM7 positively linked to activated CD8 T cells and negatively to myeloid-derived suppressor cells. SOD1 and TOMM7 are regulated by 4 miRNAs and 71 long noncoding RNAs (lncRNAs). Seventeen potential AD drugs, including urea and nitric oxide, were predicted. Two key genes, SOD1 and TOMM7, related to mitochondria and PCD, were identified as potential targets for understanding AD's etiology, detection, and therapeutic approaches.\n\nID: 41846014\nTitle: The role of IRF5 in Microglia-Mediated neuroinflammation in ALS.\nAbstract: The occurrence and development of amyotrophic lateral sclerosis (ALS) involve neuroinflammatory responses, in which microglial activation plays a critical role. IRF5, a key regulator of inflammatory responses, is implicated in the disease mechanisms of various conditions. However, its mechanism in ALS remains unclear. This study found that IRF5 expression was significantly increased in hSOD1-G93A transgenic ALS mice and cell models, primarily localized in activated microglia. Silencing IRF5 altered microglial polarization, suppressed the release of inflammatory factors, enhanced phagocytic function, and reduced motor neuron apoptosis in a co-culture system. Mechanistic studies suggested that IRF5 may regulate microglial function through the NF-\u03baB signaling pathway. This study reveals the key role of IRF5 in microglia-mediated neuroinflammation and neuronal damage in ALS, indicating that targeting IRF5 could represent a promising treatment strategy for this disease.\n\nID: 41833275\nTitle: The role of zinc transporter 1 (ZnT1) in health and disease: From molecular mechanisms to therapeutic opportunities.\nAbstract: Zinc transporter 1 (ZnT1/SLC30A1) is a major plasma membrane-localized zinc efflux transporter and acts as a central regulator of cellular metal homeostasis. Beyond exporting Zn2+, recent evidence reveals that ZnT1 also transports Cu2+ and serves as a molecular hub linking zinc-copper interplay, redox balance, immune signaling and programmed cell death. This review summarizes current advances in ZnT1 structure, transport mechanism, regulatory networks and physiological roles across the gut-liver-immune-neuro-cardiovascular axis. We further outline its pathological involvement in Wilson disease, amyotrophic lateral sclerosis, cancer and inflammatory disorders, highlighting ferroptosis, cuproptosis and metabolic reprogramming as key downstream consequences of ZnT1 dysregulation. Emerging therapeutic approaches include small-molecule modulators, RNA-based regulation, antibody targeting and metal-based interventions. Although challenges remain-such as tissue specificity, systemic toxicity and biomarker development-ZnT1 is rapidly evolving from a basic transport protein to a promising precision medicine target. Continued efforts in structural biology, single-cell metallomics and targeted delivery systems will accelerate its clinical translation.\n\nID: 41828703\nTitle: Violet-Blue Light Photobiological Effect on Cultured Corneal and Pigment Retinal Cells.\nAbstract: Artificial optical radiation, spanning from 100 nm to 1 mm, encompasses ultraviolet (UV) and infrared (IR) light. UV light is well known for its risks on the skin and eyes. Recently, there has been growing interest in light at 405 nm (violet-blue light, VBL) due to its antimicrobial properties and perceived safety for mammalian cells when administered in controlled amounts. This research delved into the impact of 405 nm VBL on corneal and retinal pigment epithelial cell cultures. ARPE-19 and corneal BCE C/D 1b cells were exposed to VBL for varying doses, according at different exposure times, to evaluate cell viability, oxidative stress levels and apoptotic indicators. A 3D printed prototype with 14 LEDs centred at 405 nm wavelength was used to ensure uniform distribution of light during exposure. Cell viability was assessed using the MTT assay, measurement of oxygen species (ROS) production was carried out, and Western blot analysis was employed to study catalase and SOD-1 expression and apoptotic marker activation. Exposure to 405 nm VBL for both term (3 h) and prolonged durations (9 h) led to a weak decrease in cell viability in ARPE-19 cells, whereas the effect on BCE C/D 1b cells was negligible. There was no increase in ROS production, with catalase and SOD-1 expression remaining stable, suggesting no pro-oxidative stress effects in these models. Moreover, no activation of caspase-3 and accumulation of cytochrome C were found. Based on our results, exposure to 405 nm light at regulated levels does not pose a threat to the viability of the tested cell lines and does not lead to oxidative stress and apoptosis under these conditions. These results suggest a favourable cytocompatibility profile for these specific ocular cell models, laying a foundation for further investigations into its ocular safety.\n\nID: 41823531\nTitle: Ferritin in ferroptosis: Implications for neurodegenerative diseases (Review).\nAbstract: Neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis, are characterized by progressive loss of neurons. Although the precise pathogenesis of such diseases is complex and multifactorial, several molecular pathways have been implicated, including the aggregation of misfolded proteins, mitochondrial dysfunction, oxidative stress, neuroinflammation and disrupted iron homeostasis. Emerging evidence has underscored the pivotal role of ferroptosis, an iron\u2011dependent, non\u2011apoptotic form of cell death, in neurodegenerative disease progression. Ferritin, characterized by a 24\u2011subunit hollow sphere structure composed of heavy and light chains, plays a key role in the network regulating cerebral iron homeostasis. In response to cellular iron overload, ferritin expression is upregulated to sequester labile iron and mitigate Fenton reaction\u2011mediated toxicity, thus exerting a cytoprotective function. Paradoxically, ferritin can be degraded via ferritinophagy, a selective autophagic process that releases toxic ferrous iron and directly triggers ferroptosis. This review systematically reviews the role of ferritin within the iron homeostasis network to elucidate the connection between the dysregulation of iron metabolism and the pathological mechanisms of neurodegenerative diseases. The study focused on the potential role of ferritin as a biomarker for early diagnosis, therapeutic strategies targeting ferritin pathways to restore iron homeostasis and the clinical translational value of magnetic resonance imaging\u2011based non\u2011invasive quantification of cerebral iron deposition. It is crucial to elucidate the multidimensional roles of ferritin in neurodegeneration to provide a theoretical foundation for precision diagnostic and therapeutic approaches.\n\nID: 41807703\nTitle: TDP-43 pathology triggers neuroinflammation and cognitive impairment by inducing microglial necroptosis.\nAbstract: Pathological TAR DNA-binding protein-43 (TDP-43) is a defining feature of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and Alzheimer's disease (AD). However, the mechanism by which TDP-43 pathology disrupts microglial function and drives neuroinflammation remains unclear. In this study, we demonstrated that cytoplasmically mis-localized TDP-43 exacerbated neuroinflammation, induced cell death, and impaired phagocytic function in microglial cells, primarily through receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis. Pharmacological inhibition of RIPK3 with GSK872 markedly attenuated these pathological effects in vitro. These findings were further corroborated in a murine model with cytoplasmic TDP-43 mis-localization, where GSK872 treatment remarkably alleviated neuroinflammation and restored cognitive deficits. Mechanistically, our findings indicate that the nuclear depletion of TDP-43, resulted from its cytoplasmic mis-localization, impairs its ability to transcriptionally repress the Ripk3 gene, subsequently leading to RIPK3 upregulation and activation of RIPK3-dependent necroptosis. Collectively, our findings establish RIPK3-dependent necroptosis as a critical driver of TDP-43 pathology-mediated neuroinflammation and identified necroptosis as a promising therapeutic target in TDP-43-associated neurodegenerative disorders.\n\nID: 41789732\nTitle: 3D Artificial Skin Model As a Novel Strategy for the Detection of Pyroptosis-Cascade Activation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a severe adult-onset neurodegenerative disease with limited treatment approaches. Evidence has shown that degeneration of cutaneous nerves may reflect neurodegenerative processes occurring within the central nervous system. Although skin biopsy is widely adopted in clinical practice, the procedure is invasive and requires multiple patients' tissue removals. Therefore, we developed a 3D innervated skin model by combining 3D printing of methacrylated hyaluronic acid as an innovative tool for better reproducing the dermis and epidermis and electrospinning of polylactic acid for mimicking skin innervation. Later, 3D artificial skin was colonized with a preneuronal cell line (SH-SY5Y) and fibroblasts isolated from skin biopsy of ALS patients at different disease stages. 3D skin possesses a porosity suitable for cell colonization and a high stability. Importantly, biological results reveal an increase of TAR DNA-binding protein 43 aggregates, NOD-like receptor pyrin domain containing protein 3, interleukin (IL)-18, IL-6, and nitrites in 3D skin of ALS patients, thus indicating pyroptosis activation linked to neurodegeneration. This physiologically relevant 3D skin model reduces the need for repeated biopsies, allows standardized experimental conditions, and supports biomarker research and preclinical drug testing in ALS.\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: 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: 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: 42312577\nTitle: Thalamic Nuclei Atrophy in Type 1 Diabetes Mellitus Across Disease Duration.\nAbstract: Thalamic volume loss is one of the most consistent neuroimaging findings in type 1 diabetes mellitus (T1DM). However, the thalamus comprises multiple nuclei with distinct functions, and whether specific nuclei show differential vulnerability remains unclear. To investigate the characteristics of intra-thalamic nuclear atrophy in T1DM and evaluate its association with disease duration. 3.0\u2009T/T1-weighted magnetization-prepared-rapid-acquisition-of-gradient-echo (MPRAGE). Prospective. Forty-two subjects with T1DM (18-68\u2009years, 17 males/25 females) and 39 healthy controls (18-69\u2009years, 16 males/23 females). Multi-atlas-based segmentation was used to quantify volumes of 20 thalamic nuclei. Additionally, volumes of anatomical and functional subregions were derived based on topographic and functional nuclear classifications. Group differences were assessed using general linear models. Associations between thalamic volume loss and disease duration were evaluated via partial correlations and exponential regression models to estimate duration-related atrophy rates. p value <\u20090.05 was considered significant. Participants with T1DM showed significant bilateral reductions in total thalamic volume (left: 7.6%, Cohen's d\u2009=\u20090.91; right: 8.0%, Cohen's d\u2009=\u20090.95). The most pronounced atrophy was observed in the anterior, medial, and lateral thalamic subregions, with volume reductions of 15.8%, 8.6%, and 7.3%, respectively, particularly in cognition- and motor-related nuclei (9.4% and 9.2%, respectively). Longer disease duration was significantly associated with smaller thalamic volumes in the bilateral whole thalamus (rleft\u2009=\u2009-0.48 and rright\u2009=\u2009-0.46), as well as in the Pul (rleft\u2009=\u2009-0.64 and rright\u2009=\u2009-0.57), VLp (rleft\u2009=\u2009-0.39 and rright\u2009=\u2009-0.38), and MD-Pf nuclei (rleft\u2009=\u2009-0.55 and rright\u2009=\u2009-0.37), and in the left LGN (r\u2009=\u2009-0.43). Estimated disease-duration-related annualized atrophy rates exceeded age-related rates in several left-sided nuclei, including the MD-Pf (-0.67%), Pul (-0.69%), and LGN (-0.75%). T1DM is associated with spatially heterogeneous atrophy of thalamic nuclei, with preferential involvement of the anterior, medial, and lateral subregions. Disease duration seems to accelerate neurodegenerative changes. 2. Stage 2. This study investigated changes in thalamic nuclei associated with type 1 diabetes mellitus (T1DM). Previous studies have not clarified whether all thalamic nuclei are equally affected in T1DM. Thalamic structural changes were compared between patients with T1DM and healthy controls, and their associations with disease duration were analyzed. Patients with T1DM showed spatially heterogeneous volume loss across thalamic nuclei, with greater shrinkage in cognitive\u2010 and motor\u2010related subregions. Longer disease duration was associated with accelerated neurodegenerative changes. These findings extend previous research on generalized thalamic atrophy and provide valuable insights into the neuroanatomical basis of clinical symptoms in T1DM.\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: 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: 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: 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: 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\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: 42177227\nTitle: Nrf2/Bach1-ARE pathway are involved in the ameliorative effects of astaxanthin on D-galactose-induced liver and brain aging and injury.\nAbstract: Astaxanthin (ATX), a natural antioxidant whose benefits in age-related liver and kidney damage remain unclear. We established a D-galactose-induced ageing model in rats and observed the daily behaviour of the rats. Using staining methods to detect ROS, apoptosis and histopathological changes in liver and brain tissue. Determination of antioxidant levels of IL-2, IL-6 and AGES in rats. Assessment of cognitive function using the Morris water maze and ChAT. The mRNA and protein expression levels of Nrf2, Bach1, SOD1, SOD2, HO-1 were determined by real-time PCR and Western blotting. To investigate the role of the Nrf2/Bach1-ARE pathway, we used ML385, a specific inhibitor of the Nrf2 pathway, to treat rats in the inhibitor group. Aging rats showed impaired learning and memory, along with decreased levels of neurotransmitters and antioxidant enzymes. ATX and vitamin E (VE) interventions significantly alleviated these symptoms and activated the Nrf2/Bach1-ARE pathway in liver and brain tissues of aged SD rats. Furthermore, the protective effects of ATX were attenuated by the addition of the Nrf2 inhibitor ML385. ATX reduces oxidative stress and ameliorates liver and brain damage in aged rats via activation of the Nrf2/Bach1-ARE pathway.\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: 42158360\nTitle: Apoptosis-related gene model predicts the prognosis in patients with acute myeloid leukemia.\nAbstract: Acute myeloid leukemia (AML) is a hematological malignancy with a high mortality rate and heterogeneous prognosis. Traditional risk stratification is based on the genetic classification in the 2022 guidelines of the European Leukemia Net. However, the risks of some patients remain unclear, and other prognostic assessment methods are required to improve the risk assessment of these patients. Apoptosis-related genes (ARGs) play critical roles in regulating the survival and drug resistance of AML cells. Therefore, we collected gene expression and clinical data from patients with AML from The Cancer Genome Atlas Acute Myeloid Leukemia (TCGA-LAML) datasets to develop a risk assessment model based on 5 ARGs. Using the least absolute shrinkage and selection operator Cox regression (LASSO-Cox) model, we identified 5 key ARGs (DDIT4, HSP90B1, ENO1, SOD1, and SLC7A11) and constructed a 5-ARG prognostic model. Using this model, we successfully stratified patients in both TCGA-LAML training and independent external validation cohorts, with high-risk patients consistently exhibiting significantly poorer clinical outcomes. In addition, high-risk patients exhibited significant enrichment in pathways related to TP53 dysfunction, mechanistic target of rapamycin complex 1 (mTORC1) signaling activation, and pro-inflammatory responses, which were closely correlated with NPM1c-FLT3 co-mutations. Decitabine, sunitinib, and MK-1775 were identified as potential therapeutic agents. In summary, we established a 5-ARG prognostic model that may facilitate risk stratification and inform therapeutic decision-making in AML.\n\nID: 42105621\nTitle: Silica nanoparticles suppress porcine oocyte maturation via oxidative stress, metabolic dysfunction, and impaired cholesterol trafficking.\nAbstract: Silica nanoparticles (SiNPs), as common feed additives, are widely applied in livestock diets and pose potential risks to reproductive health owing to their tissue accumulation. In the present study, we explored the effects and underlying mechanisms of SiNPs exposure during in vitro maturation (IVM) of porcine oocytes. The results showed that SiNPs significantly suppress porcine oocyte maturation as evidenced by decreased first polar body (PB1) release rate. Notably, SiNPs significantly induced abnormal expansion of cumulus cells and impaired gap junction intercellular communication (GJIC), accompanied by decreased Connexin 43 (CX43) expression and aberrant F-actin structure. Furthermore, DCFH-DA staining showed that SiNPs significantly increased reactive oxygen species (ROS) levels and malondialdehyde (MDA) content, and decreased the mRNA levels of antioxidant-related genes, including SOD1, SOD2, CAT, GPX1, PRDX2, and NRF2. JC-1 staining showed that SiNPs significantly induced mitochondrial dysfunction via diminished mitochondrial membrane potential (\u0394\u03a8m) and aberrant distribution, and decreased the mRNA levels of energy metabolism-related genes, such as NOX4 and COX2. Additionally, SiNPs significantly disrupted lysosomal function and cholesterol trafficking and decreased the mRNA levels of LDLR, NPC1, NPC2, and LAMP2, leading to reduced free cholesterol levels and the mRNA levels of estrogen synthesis-related genes, including STAR, CYP19A1, and HSD-3\u03b2. Collectively, SiNPs suppress porcine oocyte maturation, at least partly, through oxidative stress, metabolic disruption, and impaired cholesterol trafficking.\n\nID: 42096016\nTitle: Impact of melatonin injection in improving ovarian function in aged female pigeon.\nAbstract: Melatonin (MT) has been shown to extend laying period in aged hens, but its effects on aging pigeons remain unclear. 36 pairs of 5-year-old White King pigeons were assigned to either a treatment group receiving 1\u00a0mg of MT for five days or a control group given saline. The effect of MT injection on egg production in pigeon, assess histological characteristics of follicles, antioxidant parameters level and the related gene mRNA levels, steroid hormone levels and the expressions of synthesis genes on the fifth day of the laying interval. MT treatment significantly improved various aspects of egg quality. Moreover, MT increased follicle diameter and granulosa cell layer (GCL) thickness (P\u2009<\u20090.05). MT levels were elevated in plasma and hierarchy follicles yolks (P\u2009<\u20090.05). Progesterone concentrations rose in plasma (P\u2009<\u20090.05), however, estradiol levels decreased in plasma, F1 and F2 yolks (P\u2009<\u20090.05). MT also reduced ROS and MDA levels in plasma and F1 yolk (P\u2009<\u20090.05). Meanwhile, activities of SOD, TAC, and GSH-PX were significantly increased (P\u2009<\u20090.05). MT upregulated SOD1, CAT, and BCL2 mRNA levels in ovary and F1 GCL (P\u2009<\u20090.05). MT significantly increased ovarian expressions of HSD3B1 and CYP11A1, reducing HSD17B1 mRNA levels (P\u2009<\u20090.05); In F1 and F2 GCL, CYP11A1, CYP17A1, and CYP19A1 expressions were all elevated (P\u2009<\u20090.05). These findings suggest that MT promotes hierarchy follicle maturation, reduces apoptosis, thus extending egg-laying period in aging pigeons.\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: 42076688\nTitle: Protective Effects Assessment of Combined Extracts from Periplaneta americana Residues and Cybister chinensis Motschulsky on Feline Renal Cells: In Vitro Evidence Related to Inflammation, Oxidative Stress, and Fibrosis.\nAbstract: With the rising prevalence of feline kidney diseases, effective preventive and therapeutic strategies are urgently needed. This study evaluated the effects of Cybister chinensis extracts (CCME) and Periplaneta americana residue extracts (PAE) on inflammation-associated, oxidative stress-related, and fibrosis-related responses in Crandell-Rees Feline Kidney (CRFK) cells. Using MTT assays, flow cytometry, and qPCR, we assessed cytoprotection in models of lipopolysaccharide (LPS)-, hydrogen peroxide (H2O2)-, and palmitic acid (PA)-induced injury. Preliminary HPLC fingerprint analysis of three batches of a combined extract from Periplaneta americana residues and Cybister chinensis Motschulsky (CPCE) revealed similar chromatographic profiles, indicating good batch-to-batch consistency. Within non-cytotoxic ranges, CPCE increased cell viability and reduced apoptosis in injured CRFK cells. Anti-inflammatory effects were evidenced by significant downregulation of TNF-\u03b1 and IL-6 mRNA. Potential antioxidant-related effects were suggested by decreased expression of oxidative stress-responsive genes SOD1, CAT, and GSTP1. In the PA model, anti-fibrotic potential was supported by reduced TGFB1 expression, accompanied by improvements in inflammatory and oxidative stress markers, and by decreased levels of fibrosis-associated markers \u03b1-SMA, COL I, and HCB III. These findings suggest that CPCE exerts cytoprotective effects in vitro, potentially through modulation of inflammation, oxidative stress, and fibrosis.\n\nID: 42008451\nTitle: Preclinical study of red dragon fruit (Hylocereus polyrhizus) betacyanins in the G93A mutant hSOD1 mouse model of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by loss of cortical and spinal motor neurons, oxidative stress, neuroinflammation, and mitochondrial dysfunction. Betacyanins, betalain pigments found in red dragon fruit and beetroot, display powerful anti-inflammatory and free-radical scavenging properties which may help ameliorate ALS pathology and slow disease progression. The present study characterized the therapeutic effects of a betacyanin-rich red dragon fruit extract (DFE) in the G93A mutant hSOD1 transgenic mouse model of ALS. Mice were treated orally with 5% (v/v) DFE in drinking water ad libitum, from disease onset until end-stage. DFE treatment had a statistically significant effect on survival, with an approximate 13-day extension of median lifespan in the treated G93A mutant hSOD1 group. Treatment with DFE also significantly preserved muscle strength and endurance, as assessed by grip strength and rotarod behavioral testing. This was associated with a modest but statistically significant preservation of gastrocnemius muscle weight in the DFE-treated group. Histopathological analyses demonstrated improvements in NMJ size and complexity, an increase in surviving spinal cord motor neurons, and a reduction in spinal cord astrogliosis in G93A mutant hSOD1 mice treated with DFE, when compared to their untreated mutant littermates. Overall, these findings indicate that DFE, or purified betacyanin compounds, should be investigated further as potential therapeutic agents for patients with SOD1-related ALS. Additional preclinical studies in non-SOD1 models of ALS will need to be completed to determine the potential benefit of betacyanin compounds in sporadic ALS.\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: 41996987\nTitle: Decoding RNA splicing pathology: Alternative splicing in amyotrophic lateral sclerosis and its therapeutic potential.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive motor neuron loss, leading to muscle weakness, paralysis, and respiratory failure. Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival.\n\nID: 41996822\nTitle: Physiological and transcriptomic responses of the gills in Gymnocypris eckloni under acute and chronic hypoxia stress.\nAbstract: With the intensification of global warming and environmental pollution, hypoxia is an unavoidable environmental factor in aquatic ecosystems and has multiple adverse effects on fish. Gymnocypris eckloni, a representative species of the Qinghai-Tibetan Plateau, exhibits excellent adaptability to hypoxic environments, however, little is known about the hypoxic adaptation mechanisms of G. eckloni. Herein, effects of acute hypoxia for 12\u00a0h (H12S) and chronic hypoxia for different durations (H24S, H96S and H168S) on biochemical parameters and transcriptome of G. eckloni gills were investigated. We found that the gills suffered severe oxidative damage and increased anaerobic glycolysis was observed across all groups, and aerobic glycolysis was elevated in H12S. Inflammatory response, apoptosis and translation process were markedly suppressed, and signal transmission and protein synthesis process were strengthened under acute hypoxia stress. Through STEM and WGCNA, we identified several key hub genes (egln, akt, pdk1, foxo1, pfk, gapdh, gk, bax, casp8, il-8 and il-1\u03b2) related to hypoxia from 3608 DEGs, and expression of akt, gk, sdh, gapdh and ldh was significantly upregulated under hypoxia stress, and sod1, cat, bax, casp8 and ccl8 showed an opposite trend. Enrichment analysis revealed that most DEGs were significantly enriched in MAPK signaling pathway, cytokine-cytokine receptor interaction, FoxO signaling pathway, mTOR signaling pathway, glycolysis/gluconeogenesis and apoptosis. The study revealed the differences in the molecular mechanisms of G. eckloni in responding to acute and chronic hypoxia stress, and provided valuable genetic resources for breeding hypoxic-tolerant fish.\n\nID: 41983194\nTitle: Dynamic changes in excitability and viability of sporadic and SOD1-related amyotrophic lateral sclerosis iPSC-derived motor neurons.\nAbstract: To explore the dynamic changes in excitability and viability of induced pluripotent stem cells (iPSC)-derived motor neurons from sporadic amyotrophic lateral sclerosis (ALS) and compare them with SOD1-related ALS patients and healthy control. Peripheral blood samples were collected from ALS patients and healthy controls (HC) to establish the iPSC-derived motor neurons (MNs). Whole-cell patch-clamp recordings at different culture stages was made using an Axopatch 700B amplifier in combination with pClamp 11 software (Molecular Devices). The frequency of action potentials (APs) was recorded. Additionally, Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) Nick-End Labeling (TUNEL) was used to assess the apoptosis of MNs. ALS patient-derived MNs exhibited significantly higher firing rates compared to HCs at both 4-7 weeks (p = 0.004) and 7-9 weeks (p = 0.009). Further analysis revealed that SOD1-derived MNs showed significantly higher firing frequencies than sALS (p = 0.009) and HCs (p < 0.001) in 4-7 weeks. In 7-9 weeks, it remained significant between SOD1 and HC-derived MNs (p = 0.015), but became insignificant between SOD1 and sALS (p = 0.855). The apoptotic rate of sALS (Day 30: 61.37% \u00b1 9.63%; Day 60: 78.41% \u00b1 6.63%) and SOD1 (Day 30: 73.69% \u00b1 8.81%; Day 60: 60.37% \u00b1 11.53%) -derived MNs was significantly higher than those of HCs at both Day 30 (30.72% \u00b1 7.57%) and Day 60 (50.85% \u00b1 19.36%) (p < 0.001). MNs derived from both patients with mutant SOD1 and sporadic ALS exhibited increased excitability compared to HCs. The increased excitability of MNs derived from ALS patients with mutant SOD1 occurred earlier, and over time, became consistent with the excitability observed in MNs derived from sporadic ALS. The apoptosis rates of MNs showed similar trends. iPSC-derived MNs from both sporadic and mutant ALS may serve as useful cell models for ALS in future studies.\n\nID: 41981505\nTitle: Alkaline sphingomyelinase (ENPP7) attenuates DSS-induced colitis by modulating FOXO1-mediated antioxidative stress responses.\nAbstract: BACKGROUND: Alkaline sphingomyelinase (alk-SMase), also known as ectonucleotide pyrophosphatase/phosphodiesterase 7 (ENPP7), is an intestinal enzyme involved in sphingolipid metabolism and has been implicated in the regulation of inflammation. However, its role in intestinal inflammation and the underlying mechanisms remain unclear. This study aimed to investigate the role of ENPP7 in dextran sulfate sodium (DSS)-induced colitis, with a particular focus on oxidative stress and FOXO1-related signaling pathways. METHODS: ENPP7 knockout (KO) and wild-type (WT) mice were used to establish a DSS-induced colitis model. Disease severity was assessed by body weight change, disease activity index (DAI), colon length, histopathological analysis, and plasma oxidative stress markers. Levels of pro-inflammatory cytokines and antioxidant enzymes were measured using standard biochemical assays. In vitro, polarized Caco-2 cells were subjected to ENPP7 knockdown and FOXO1 overexpression to evaluate their roles in antioxidative responses. RESULTS: ENPP7 deficiency significantly aggravated DSS-induced colitis, as evidenced by greater body weight loss, higher DAI scores, and shorter colon length. This effect was accompanied by reduced FOXO1 expression, and was associated with diminished antioxidant defense and mitochondrial dysfunction-related alterations. Additionally, KO mice showed increased levels of pro-inflammatory cytokines (IL-1\u03b2 and TNF-\u03b1) and decreased activities of antioxidant enzymes (CAT and SOD1) in intestinal mucosal tissues compared with WT mice. In Caco-2 cells, ENPP7 knockdown reduced FOXO1 expression, which was associated with impaired antioxidant capacity, whereas FOXO1 overexpression partially reversed these effects. CONCLUSIONS: ENPP7 attenuates DSS-induced colitis, at least in part, by modulating FOXO1-mediated antioxidant responses, thereby influencing oxidative stress and inflammatory processes. These findings highlight ENPP7 as a potential therapeutic target for ulcerative colitis, although further mechanistic and clinical studies are warranted.\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.

The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.\n --- END ACTUAL ABSTRACT FOR 42350373 ---\n\n- ERROR: You cited ID: 42350385 for the quote: \"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).\"\n FACT: Strict Misquote Detected!

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 --- END ACTUAL ABSTRACT FOR 42350385 ---\n\n- ERROR: You cited ID: 42375949 for the quote: \"The hypothyroid model showed elevated MDA levels and cleaved caspase-3, as well as a higher Bax/Bcl-2 ratio.\"\n FACT: Strict Misquote Detected!

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 --- END ACTUAL ABSTRACT FOR 42375949 ---\n\n- ERROR: You cited ID: 42227424 for the quote: \"Giemsa staining revealed morphological changes (e.g., multinucleated cells, nuclear fragmentation) indicative of chromosome instability.\"\n FACT: Strict Misquote Detected!

Human AML MOLM-13 cells were treated with gradient concentrations (0, 120, 240, 480 \u03bcmol/L) of loganetin for 48 hours. CDK2 protein expression and its interaction with KLHL6 were analyzed by Western blot and co-immunoprecipitation (Co-IP), respectively. Cellular morphology was observed via Giemsa staining. Intracellular oxidative stress was evaluated by NBT assay. An AML mouse model was established by tail-vein injection of MOLM-13 cells (1\u00d7107/mL, 2\u00d7106 cells/mouse); bone marrow cells were analyzed by flow cytometry for hCD45+ and CD11b+ surface markers. Loganetin dose-dependently induced KLHL6-mediated CDK2 ubiquitination and degradation. The Western blot analysis results showed that the level of CDK2 protein significantly decreased with the increase of loganetin concentration (P <0.01), Co-IP confirmed that the CDK2-KLHL6 interaction was enhanced in a dose-dependent manner. Giemsa staining revealed morphological changes (e.g., multinucleated cells, nuclear fragmentation) indicative of chromosome instability in high-concentration groups (480 \u03bcmol/L). NBT assay demonstrated elevated intracellular oxidative stress (P <0.01), accompanied by downregulation of PRDX2 and upregulation of MAFB. In vivo, treated mice showed reduced bone marrow hCD45+ AML cells (P <0.05) and increased CD11b+ differentiated cells (P <0.05), and the splenomegaly was alleviated. Loganetin promotes AML cell differentiation by degrading CDK2 via KLHL6-mediated ubiquitination, synergistically enhancing oxidative stressand genomic instability. \u9a6c\u94b1\u82f7\u5143\u901a\u8fc7KLHL6\u4ecb\u5bfcCDK2\u6cdb\u7d20\u5316\u964d\u89e3\u8bf1\u5bfcAML\u7ec6\u80de\u5206\u5316\u53ca\u67d3\u8272\u4f53\u4e0d\u7a33\u5b9a\u6027. \u63a2\u7a76\u5c71\u8331\u8438\u6d3b\u6027\u6210\u5206\u9a6c\u94b1\u82f7\u5143\u8c03\u63a7CDK2\u6cdb\u7d20\u5316\u964d\u89e3\u6291\u5236\u6025\u6027\u9ad3\u7cfb\u767d\u8840\u75c5\uff08AML\uff09\u7684\u4f5c\u7528\u673a\u5236\u3002. \u91c7\u7528\u68af\u5ea6\u6d53\u5ea6\uff080\u3001120\u3001240\u3001480 \u03bcmol/L\uff09\u9a6c\u94b1\u82f7\u5143\u5904\u7406MOLM-13\u7ec6\u80de48 h\uff0cWestern blot\u68c0\u6d4bCDK2\u86cb\u767d\u8868\u8fbe\uff0cCo-IP\u68c0\u6d4bCDK2\u4e0eKLHL6\u76f8\u4e92\u4f5c\u7528\uff1b\u5409\u59c6\u8428\u67d3\u8272\u89c2\u5bdf\u7ec6\u80de\u5f62\u6001\u53d8\u5316\uff1bNBT\u5b9e\u9a8c\u8bc4\u4f30\u7ec6\u80de\u6c27\u5316\u5e94\u6fc0\u6c34\u5e73\u3002\u5efa\u7acb\u5c0f\u9f20AML\u6a21\u578b\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u5206\u6790\u9aa8\u9ad3\u7ec6\u80de\u8868\u9762hCD45+\u53caCD11b+\u7684\u8868\u8fbe\u3002. \u9a6c\u94b1\u82f7\u5143\u5242\u91cf\u4f9d\u8d56\u6027\u8bf1\u5bfcKLHL6\u4ecb\u5bfc\u7684CDK2\u6cdb\u7d20\u5316\u964d\u89e3\u3002Western blot\u5206\u6790\u7ed3\u679c\u663e\u793a\uff0cCDK2\u86cb\u767d\u6c34\u5e73\u968f\u9a6c\u94b1\u82f7\u5143\u6d53\u5ea6\u5347\u9ad8\u663e\u8457\u4e0b\u964d(P < 0.01)\uff0cCo-IP\u8bc1\u5b9eCDK2\u4e0eKLHL6\u7684\u76f8\u4e92\u4f5c\u7528\u589e\u5f3a\u3002\u5409\u59c6\u8428\u67d3\u8272\u793a\u9ad8\u6d53\u5ea6\u7ec4(480 \u03bcmol/L)\u7ec6\u80de\u51fa\u73b0\u591a\u6838\u3001\u6838\u788e\u88c2\u7b49\u67d3\u8272\u4f53\u4e0d\u7a33\u5b9a\u6027\u7279\u5f81\uff1bNBT\u5b9e\u9a8c\u8868\u660e\u6c27\u5316\u5e94\u6fc0\u6c34\u5e73\u663e\u8457\u5347\u9ad8(480 \u03bcmol/L\u7ec4OD560\u503c\u8fbe\u5cf0\u503c\uff0cP < 0.01)\uff0c\u4f34\u968fPRDX2\u8868\u8fbe\u4e0b\u8c03\u4e0eMAFB\u8868\u8fbe\u4e0a\u8c03\uff1b\u4f53\u5185\u5b9e\u9a8c\u663e\u793a\uff0c\u9a6c\u94b1\u82f7\u5143\u6cbb\u7597\u7ec4\u5c0f\u9f20\u9aa8\u9ad3hCD45+AML\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e(P < 0.05)\uff0cCD11b+\u5206\u5316\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8(P < 0.05)\uff0c\u813e\u810f\u80bf\u5927\u7a0b\u5ea6\u51cf\u8f7b\u3002. \u9a6c\u94b1\u82f7\u5143\u901a\u8fc7\u964d\u89e3CDK2\u534f\u540c\u8bf1\u5bfc\u6c27\u5316\u5e94\u6fc0\u4e0e\u57fa\u56e0\u7ec4\u4e0d\u7a33\u5b9a\u6027\u589e\u52a0\uff0c\u4fc3\u8fdbAML\u7ec6\u80de\u5206\u5316\uff0c\u4e3aAML\u6cbb\u7597\u63d0\u4f9b\u601d\u8def\u3002.\n --- END ACTUAL ABSTRACT FOR 42227424 ---\n\n- ERROR: You cited ID: 41833275 for the quote: \"We further outline its pathological involvement in... amyotrophic lateral sclerosis... highlighting ferroptosis, cuproptosis and metabolic reprogramming as key downstream consequences.\"\n FACT: Ellipses (...) are strictly forbidden.

Beyond exporting Zn2+, recent evidence reveals that ZnT1 also transports Cu2+ and serves as a molecular hub linking zinc-copper interplay, redox balance, immune signaling and programmed cell death. This review summarizes current advances in ZnT1 structure, transport mechanism, regulatory networks and physiological roles across the gut-liver-immune-neuro-cardiovascular axis. We further outline its pathological involvement in Wilson disease, amyotrophic lateral sclerosis, cancer and inflammatory disorders, highlighting ferroptosis, cuproptosis and metabolic reprogramming as key downstream consequences of ZnT1 dysregulation. Emerging therapeutic approaches include small-molecule modulators, RNA-based regulation, antibody targeting and metal-based interventions. Although challenges remain-such as tissue specificity, systemic toxicity and biomarker development-ZnT1 is rapidly evolving from a basic transport protein to a promising precision medicine target. Continued efforts in structural biology, single-cell metallomics and targeted delivery systems will accelerate its clinical translation.\n --- END ACTUAL ABSTRACT FOR 41833275 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation.\" (Source: 42350373)\n- \"We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology.\" (Source: 42350373)\n- \"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).\" (Source: 42156174)\n- \"Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis.\" (Source: 42171198)\n- \"Among these, necroptosis has recently emerged as a potential mediator linking inflammaging to neurodegeneration.\" (Source: 42054746)\n- \"biological results reveal an increase of TAR DNA-binding protein 43 aggregates, NOD-like receptor pyrin domain containing protein 3, interleukin (IL)-18, IL-6, and nitrites in 3D skin of ALS patients, thus indicating pyroptosis activation linked to neurodegeneration.\" (Source: 41789732)\n- \"Pharmacological inhibition of RIPK3 with GSK872 markedly attenuated these pathological effects in vitro.\" (Source: 41807703)\n- \"mitigated apoptosis by modulating Bax/Bcl-2 balance and reducing TUNEL-positive cells.\" (Source: 42278291)\n- \"At 2.5 Gy, cell numbers declined to near zero by 6 h (Mean normalized adherent nuclear count decreased to approximately 5% of baseline.), associated with marked nuclear abnormalities, including multinucleation and nuclear fragmentation.\" (Source: 42390647)\n- \"SiNPs significantly increased reactive oxygen species (ROS) levels and malondialdehyde (MDA) content, and decreased the mRNA levels of antioxidant-related genes, including SOD1, SOD2, CAT, GPX1, PRDX2, and NRF2.\" (Source: 42105621)\n- \"ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression.\" (Source: 42085907)\n- \"During sexual reproduction, the MICs undergo meiosis and the MAC deforms and fragments, providing a unique model to study the regulation of diverse nuclear events.\" (Source: 42186564)\n- \"Compared with control cells, STC2-overexpressing cells exhibited higher cell viability, reduced ROS accumulation, and decreased cell death.\" (Source: 42353187)\n- \"Ferroptosis is a form of regulated cell death driven by iron-dependent lipid peroxidation, which plays a pivotal role in regulating the inflammatory-immune microenvironment of central nervous system (CNS) diseases.\" (Source: 42148083)\n- \"Disulfidptosis is a recently identified form of regulated cell death driven by disulfide stress and cytoskeletal collapse under conditions of impaired reducing capacity.\" (Source: 42031063)\n\n\nINSTRUCTION: Study the actual abstracts provided.

It further evaluates the specific association between superoxide dismutase 1 (SOD1) and cell death mechanisms, including its role in apoptosis and its potential link to karyoptotic pathology in amyotrophic lateral sclerosis (ALS).\n\n### [INTRODUCTION & JUSTIFICATION]\nKaryoptosis constitutes a distinct form of cell death regulated by the p38 kinase signaling pathway, which controls the stability of the nuclear lamina protein LaminB1 via direct phosphorylation. In contrast, apoptosis in ALS-linked models often involves oxidative stress-mediated pathways and specific genetic contributions like SOD1 mutations. While SOD1 mutations are well-documented to induce apoptosis, direct empirical evidence linking SOD1 protein specifically to the induction of karyoptosis remains limited or absent in the provided dataset. Both processes appear to represent distinct, though sometimes convergent, pathways of neuronal loss in proteotoxic conditions.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the cellular expulsion of nuclear material, a morphological feature distinct from the chromatin condensation and membrane blebbing typical of classical apoptosis.\n* SOD1 mutations in ALS are traditionally linked to protein misfolding, aggregation, and the subsequent induction of apoptosis.\n* The p38 kinase signaling pathway serves as a regulatory switch for karyoptotic cell death by modulating nuclear lamina structural integrity.\n* Neurodegeneration in ALS/FTD pathology involves complex crosstalk between different regulated cell death forms, including apoptosis, ferroptosis, necroptosis, and karyoptosis.\n* Systemic iron homeostasis and the sequestration of labile iron by ferritin are critical, as their dysregulation triggers ferroptosis, which often overlaps with the stressors inducing apoptosis and karyoptosis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"abstract_text": "ID: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material.

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 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.

DNA damage induces NAD+ loss and an increased NMN/NAD+ ratio by hyperactivating poly(ADP-ribose) polymerase 1 (PARP1), which triggers the parthanatos cell death pathway. Multiple mechanistically distinct DNA-damaging agents activate SARM1 and induce axon degeneration following PARP1 activation. Remarkably, SARM1 is required for key steps downstream of hyperactivated PARP1, which are pathognomonic of parthanatos, including mitochondrial depolarization, nuclear translocation of apoptosis-inducing factor (AIF), and cell death. Hence, SARM1 is an essential component of neuronal parthanatos. Moreover, complex neurodegenerative stimuli whose mechanisms include activation of parthanatos, such as 1-methyl-4-phenyl-pyridinium (MPP+) dopaminergic neuron toxicity and N-methyl-D-aspartate (NMDA) excitotoxicity, are potently protected by SARM1 inhibition. These findings place SARM1 at the nexus of multiple mechanisms driving neuronal cell death, thereby greatly expanding the potential clinical utility of SARM1 inhibitors beyond diseases of axon loss."

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates."

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.

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.

This study evaluated the neuroprotective potential of caffeic acid phenethyl ester (CAPE) against MTME\u2009+\u20095-induced neurotoxicity in an ALS-like pathology model. CAPE (50 and 100\u00a0mg/kg., p.o.) demonstrated significant therapeutic efficacy by improving motor and cognitive deficits, restoring oxidative balance, and mitigating neuroinflammatory and apoptotic pathways. Behavioral assessments, including the open field, grip strength, forced swim, and Morris water maze, highlighted CAPE's ability to restore neuromuscular coordination and cognitive function in a dose-dependent manner. Cellular and Molecular analyses revealed that MTME+5 exposure significantly disrupted Klotho/SIRT-1/Nrf2/HO-1 antioxidant signaling, increased pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and elevated apoptotic markers (Bax, caspase-3) while depleting anti-inflammatory cytokines (IL-10) and neuroprotective proteins.

Furthermore, CAPE normalized neurotransmitter imbalances, including acetylcholine, dopamine, GABA, serotonin, and glutamate, alleviating excitotoxicity.

Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS."

Disruption of ER function results in protein misfolding and ER stress, which activate the unfolded protein response (UPR). While the three canonical UPR branches, inositol-requiring enzyme 1 (IRE1), protein kinase RNA-like endoplasmic reticulum kinase (PERK), and activating transcription factor 6 (ATF6), have been extensively studied, the mechanisms that coordinate their activities and ultimately dictate survival or death remain poorly understood. Transmembrane P24 trafficking protein 9 (TMED9), a cargo receptor that cycles between the ER and Golgi, has been implicated in protein quality control under pathological conditions, but its physiological role in ER proteostasis and UPR signaling is unclear. The ER stress response was studied in cellular human models including normal epithelial cells and patient-derived pediatric glioma cultures. To define the regulatory mechanisms dictating TMED9 expression, quantitative Reverse Transcription polymerase chain reaction (qRT-PCR), luciferase reporter assay, and western blotting were employed. To elucidate TMED9 function, loss-of-function approaches, including clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9-mediated knockout and small interfering RNA knockdown were used in combination with RNA-seq and live imaging. Protein stability was tested by pulse-chase experiments, ubiquitination, and degradation analyses. To study the implications of TMED9 activation, we screened curated gene expression datasets from the European Molecular Biology Laboratory- European Bioinformatics Institute (EMBL-EBI) Expression Atlas and employed live-cell imaging-based assays and functional assays (cell viability, apoptosis, migration, and self-renewal). Our study uncovers a physiological role for TMED9 in ER proteostasis and UPR signaling. We show that, under ER stress, TMED9 expression is transcriptionally induced by the IRE1-spliced X-box binding protein 1 (XBP1s) pathway via a conserved unfolded protein response element (UPRE)-like element in its promoter. Removal of TMED9 selectively impairs ATF6 activation without altering IRE1 or PERK signaling, resulting in increased sensitivity to ER stress-induced apoptosis. Mechanistically, we identify TMED9 as a stress-induced stabilizer of ATF6 that prevents its ubiquitin-dependent proteasomal degradation. Functionally, TMED9 regulation is exploited by tumor cells, which sustain IRE1-XBP1s activity to upregulate TMED9, thereby enhancing survival under ER stress conditions. Collectively, our findings establish TMED9 as a critical regulator of ER stress adaptation. TMED9 emerges as a molecular mediator that links IRE1-dependent transcriptional response to ATF6 stabilization, ultimately supporting increased secretory demand under stress conditions and in cancer development."

A comparative study was conducted to analyze the effects of probiotics and IF on SD-induced neuropsychological disturbances and compromised muscle endurance. Forty albino Wistar rats were randomly assigned to four groups. The NSD group was maintained on a standard chow diet for 12\u00a0weeks. The SD group followed an SD regimen for 72\u00a0h per week over 8\u00a0weeks, starting from the fifth week. The SDP group received probiotics at a dose of colony-forming units (CFUs)/100\u00a0g/day for 4\u00a0weeks prior to SD, followed by 8\u00a0weeks of concurrent probiotic administration with SD. The SDIF group underwent an alternate-day fasting regimen for 4\u00a0weeks before SD, followed by 8\u00a0weeks of simultaneous SD combined with IF. Neuropsychological functions and exercise capacity were tested, and then the brains were carefully dissected, sectioned, and processed for hematoxylin and eosin, cresyl violet, and immunohistochemical staining. Inflammatory markers, including interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1), and hippocampal expression of the circadian locomotor output cycles kaput (CLOCK) gene, were significantly elevated in the SD group. Conversely, it showed significant decreases in endurance, exploratory behavior, hippocampal superoxide dismutase (SOD) activity, and fecal short-chain fatty acids (SCFAs). Histological analysis also revealed hippocampal gliosis, apoptosis, CA1 pyramidal cell degeneration, layer disorganization, and upregulation of glial fibrillary acidic protein (GFAP), NF-\u03baB, and cleaved caspase-3.

Mild cognitive impairment (MCI), a transitional stage between normal aging and the onset of dementia, is thought to represent an early phase of this pathological continuum. Studies at the cellular level suggest that the conditions impair the maintenance of established neuronal processes/networks and restrict their capacity for elongation or re-elongation. They may also attenuate the activation and process extension of quiescent neural progenitor or stem-like cells. These early cellular changes precede overt neurodegeneration in neural tissue and are likely to contribute to cognitive decline. They highlight the importance of in vitro models for identifying molecular targets involved in recovery from disease. In this study, we investigated the effects of aggregated A\u03b2 (25-35) on neuronal process elongation and associated intracellular events in the N1E-115 cell line, a widely used model of neuronal differentiation. Addition of aggregated A\u03b2 to cultured N1E-115 cells attenuated process elongation in a concentration-dependent manner. This morphological impairment was accompanied by decreased expression of neuronal differentiation markers. In contrast, at the half-maximal inhibitory concentration for process elongation, long-term cultured cells did not exhibit apparent process retraction or degenerative morphology. This mild but progressive impairment, without extensive cell death, is consistent with the cellular features of early-stage conditions rather than advanced Alzheimer's pathologies. Similar results were observed in primary cortical neurons. A\u03b2 also decreased the level of GTP-bound Ras and phosphorylation of the downstream mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK). Furthermore, treatment with hesperetin, a bioactive flavonoid compound, recovered the A\u03b2-induced inhibition of neuronal process elongation. Hesperetin also restored Ras and MAPK/ERK states, suggesting that its effects are associated, at least in part, with modulation of signaling through Ras and MAPK/ERK. Our findings suggest that hesperetin may serve as a useful molecular probe for modulating early cellular responses associated with Alzheimer's disease-related pathology. This in vitro model might serve as a useful platform for investigating the molecular target candidates involved in recovery from nervous system disorders."

These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made."

Tartrazine was reported to induce hepatotoxicity, however, the effects of tartrazine on nuclear factor erythroid two-related factor two (Nrf2) signaling and endoplasmic reticulum (ER) stress pathways in rat liver have not been investigated. Therefore, this study aimed to investigate the effects of tartrazine on Nrf2 signaling and ER stress pathways in rat liver, to examine the potential therapeutic effects of lycopene, quercetin, and silymarin, and to investigate the mechanisms through which they may mitigate tartrazine-induced liver injury. Rats were allocated into five experimental groups including a normal control group and a tartrazine group that received tartrazine (10 mg/kg) orally for 13 weeks. The lycopene, quercetin, and silymarin groups received tartrazine (10 mg/kg) for 13 weeks and were treated with lycopene (10 mg/kg), quercetin (50 mg/kg), and silymarin (150 mg/kg), respectively, for the last 8 weeks. Tartrazine-induced liver injury was characterized by increased alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase serum levels and histopathological changes in the liver. Furthermore, tartrazine suppressed hepatic Nrf2 signaling and induced ER stress. Hepatic levels of malonaldehyde and caspase-3 were increased, while the levels of superoxide dismutase activity and glutathione and B cell lymphoma-2 were decreased. Moreover, hepatic transforming growth factor-beta one levels and collagen deposition were increased. Treatment with lycopene, quercetin, and silymarin ameliorated the tartrazine-induced changes, upregulated Nrf2 signaling and alleviated ER stress. Our findings suggest that lycopene, quercetin, and silymarin may provide a promising therapeutic approach against tartrazine-induced liver injury."

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."

Our understanding of the mechanisms of irAE in the brain is still evolving, and we recently demonstrated that ICI (blockade of CTLA-4 and PD-1) perturbs hippocampal-dependent memory function by derailing neuro-immune homeostasis and compromising synaptic integrity. However, the spatial patterns and the cell-type-specific molecular mechanisms underlying ICI-related brain dysfunction remain not well-defined. To address this gap, we performed spatial transcriptomic profiling of the hippocampal region using multiplexed error-robust fluorescence in situ hybridization (MERFISH) to map gene expression at single-cell resolution. By integrating spatial single-cell data with bulk RNA-seq, we define the distribution of microglia, astrocytes, synaptic, and neuroinflammatory markers, and determine how ICI reshapes hippocampal cellular composition in a syngeneic murine melanoma model. MERFISH revealed upregulation of microglial, astrocytic, oligodendrocytic, and T cell markers post-ICI treatment, revealing unique pathways driving neuroinflammation, synaptic function, and cellular signaling. Furthermore, immunofluorescence analysis of postmortem brains from patients treated with ICI corroborates our findings of ICI-related immune activation of microglia. Finally, using a conditional deletion model, we show that T cells are indispensable for ICI-driven microglial activation. Altogether, our study provides a high-resolution spatial framework for understanding irAEs in brain function and a T cell-microglia crosstalk axis as a driving mechanism of dysregulated neuro-immune homeostasis during ICI."

Reduced oligodendroglial support has been implicated in ALS progression but remains mechanistically unexplained. Here, using a mutant superoxide dismutase 1 (SOD1-G37R) mouse model of familial ALS, Cre-mediated excision of the mutant SOD1 gene within the oligodendrocyte lineage prior to myelin compaction is shown to slow disease onset, improve motor performance, and prolong survival. In contrast, silencing mutant SOD1 expression within oligodendrocytes after myelin compaction failed to ameliorate disease phenotype. Electron microscopy is used to identify aggregation of mutant SOD1 within paranodal loops and the inner periaxonal tongue of 'myelinic nanochannels', narrow cytosolic compartments for the diffusion of metabolites and motor-driven transport processes. In a second mouse model (SOD1-G93A) of familial, SOD1 mutant-mediated ALS, we show that induction of excessive myelin compaction and myelinic channel collapse (by depletion of CNP from myelin) accelerates disease and diminishes survival. Our data support loss of myelinic channel integrity as a contributor to familial ALS disease initiation and progression, findings likely relevant to neurodegenerative disease involving other aggregation prone proteins that are expressed in myelinating oligodendrocytes. Oligodendrocytes have been implicated in the progression of amyotrophic lateral sclerosis (ALS) but the underlying mechanisms have remained obscure. Here we show in genetic mouse models that the familial ALS causing isoform of a ubiquitously expressed mutant enzyme (SOD1) aggregates in cytosolic channels within myelin that are responsible for delivery of transporters and nutrients necessary to support the axonal compartment. ALS disease progression was accelerated in mice when myelinic channels were collapsed by deleting CNP, a structural protein necessary for myelinic channel maintenance. Disruption of transport through myelinic channels by aggregation of mutant SOD1 may perturb oligodendrocyte support of motor axons and contribute to disease in this form of ALS."

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"How does karyoptosis occur compared to apoptosis? SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis evaluates the mechanistic differences between apoptosis and karyoptosis within the context of amyotrophic lateral sclerosis (ALS). It investigates the functional role of superoxide dismutase 1 (SOD1) in both regulated cell death pathways to determine if SOD1 pathology extends to karyoptotic neuronal death.\n\n### [INTRODUCTION & JUSTIFICATION]\nApoptosis and karyoptosis represent distinct cellular death modalities. Apoptosis is a well-characterized programmed cell death pathway, whereas karyoptosis is identified as a unique mechanism induced specifically by proteotoxic stress, characterized by nuclear degeneration and the cellular expulsion of nuclear material. Karyoptosis is mechanistically regulated by the p38 kinase signalling pathway, which modulates the stability of LaminB1 via direct phosphorylation. In contrast, apoptosis is frequently triggered by factors such as mitochondrial dysfunction, reactive oxygen species (ROS) accumulation, and dysregulated signaling axes.\n\nEvidence confirms that SOD1 is heavily implicated in ALS pathophysiology, both as a causal mutation and as a protein prone to toxic aggregation. SOD1 mutations are linked to apoptosis through pathways involving the BAX/Bcl-2 ratio, caspase-3 activation, and oxidative stress. Regarding karyoptosis, evidence indicates that karyoptotic features are present in ALS/FTD models where proteotoxic stress is the primary driver. While SOD1 aggregation is a classic hallmark of ALS pathology, its specific involvement as a direct mediator of the p38/LaminB1-driven karyoptotic pathway requires further specific mechanistic studies beyond the general understanding that proteotoxic stress\u2014often exacerbated by mutant proteins\u2014initiates karyoptosis. The literature establishes that karyoptotic features are observable in ALS/FTD contexts, providing a plausible, though not explicitly confirmed, intersection between SOD1-mediated proteotoxicity and karyoptotic death.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the direct expulsion of nuclear material, a morphological hallmark distinct from the apoptotic condensation patterns.\n* The p38 kinase pathway acts as a regulatory node for karyoptosis by modulating LaminB1 stability.\n* SOD1 aggregates in myelinic nanochannels contribute to oligodendrocyte-mediated axonal support loss, distinct from neuronal death.\n* Mutations in SOD1 directly destabilize the local protein structure, promoting $\\beta$-sheet-driven amyloid fibrillation.\n* Oxidative stress serves as a common upstream signal for both apoptosis and other cell death pathways, including PARP1-dependent parthanatos.\n* SARM1 is required for neuronal parthanatos, effectively bridging DNA damage-induced NAD+ loss and cell death.\n* COMMD1 knockdown enhances copper incorporation into SOD1, providing a potential strategy to prevent misfolding-induced apoptosis.\n* Karyoptotic death has been identified in post-mortem tissues of patients with FTD and Alzheimer's disease.\n* Proteasomal degradation of CHK1 in cells with TDP-43 or FUS inclusions links DNA damage accumulation to ALS pathogenesis.\n* Spatial sampling bias in spinal cord segments accounts for significant variability (60%) in reported motor neuron loss in ALS models.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This review clarifies the dual function of poly(ADP-ribose) polymerase 1 (PARP1) in AD pathogenesis, emphasizing its role in mediating parthanatos, a unique caspase-independent cell death mechanism. We analyze contemporary literature regarding PARP1 expression, parthanatos signaling, and pharmaceutical treatments in AD models. In addition, PARP1 exhibits context-dependent duality: its physiological nuclear expression in hippocampus neurons is essential for memory consolidation and decreases early in cognitive impairment, suggesting a correlative association with synaptic malfunction. In contrast, overactivity of PARP1 resulting from A\u03b2-induced oxidative stress and DNA damage induces neurodegeneration via multiple pathways, including NAD+/ATP exhaustion leading to metabolism collapse, creation of the AIF-MIF complex promoting parthanatos, NF-\u03baB-induced neuroinflammation, dysregulation of mitophagy, and disruption of the neuroprotective SIRT1 signaling pathway. The overactivity contributes to a positive feedback loop, where PARP1 intensifies A\u03b2 and tau protein accumulation while simultaneously disrupting the BBB. In preclinical models of AD, genetic knockout, pharmacologic agents such as PJ34 and MC2050, or precursors of NAD+ such as nicotinamide and NMN attenuate A\u03b2 deposition, normalize metabolism, and ameliorate cognitive decline. The PARP1/parthanatos pathway is at the center of the confluence of oxidative stress, DNA damage, metabolism disorder, and neuroinflammation in AD. Metformin and other PARP1 inhibitors offer intriguing treatment options. PARP1's cell-type- and intracellular location-dependent activity necessitates careful consideration of context, dose, and disease stage while developing therapies. The present understanding in this review could inform future research on PARP1 regulation in AD clinical practice.\n\nID: 42406192\nTitle: Dissecting PANoptosis in the Nervous System: A Unified Cell-Death Mechanism Driving Neuroimmune Activation and Chronic Neuroinflammation.\nAbstract: PANoptosis, a collective form of programmed cell death that includes apoptosis, necroptosis, and pyroptosis, is turning out to be a key player in the neuroimmune activation and sustaining chronic neuroinflammation in the nervous system. PANoptosis, in contrast to single cell death mechanisms, is a web of events coordinating neuronal death, glial cell changes, and inflammatory signals, being implicated in the initiation and progression of neurodegenerative and neuroinflammatory diseases. This review compiles current knowledge of the molecular pathways of PANoptotic signaling, its interaction with autophagy and immune pathways, and the in vivo models utilized for its pathogenic role in the central nervous system. We also tackle translational hurdles such as biomarker identification, therapeutic safety, disease, stage precision, and patient heterogeneity, which all point to the necessity of highly accurate interventions. Moreover, novel techniques combining systems biology, AI-based target identification, and personalized neuroimmunomodulation may effectively harness PANoptosis regulation to be both controlled and disease-specific. Through bridging the gap between the mechanistic insights and the translational perspectives, this review points out that PANoptosis provides a comprehensive basis for neuroimmune-associated pathology and represents a viable target for novel therapeutic approaches to counteract both chronic neuroinflammation and neurodegeneration.\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: 42402732\nTitle: Alcohol-induced structural and cellular brain alterations: molecular and histopathological mechanisms.\nAbstract: Chronic alcohol consumption is a leading cause of acquired neurodegeneration with well-documented structural and ultrastructural brain alterations. This review analyzes the cellular and molecular mechanisms underlying alcohol neurotoxicity, integrating findings from animal models, human post-mortem studies, and neuroimaging investigations. Ethanol crosses the blood-brain barrier and generates toxic metabolites including acetaldehyde and reactive oxygen species, triggering oxidative stress, lipid peroxidation, and mitochondrial dysfunction. Chronic exposure induces glutamatergic and gamma-aminobutyric acid (GABA)ergic adaptations leading to excitotoxicity during withdrawal. Cell death occurs through apoptotic, necrotic, and necroptotic pathways, while microglial and astrocytic activation perpetuates neuroinflammation. Histopathological (HP) changes include selective neuronal loss in the prefrontal cortex, hippocampus, and cerebellum, dendritic simplification, and synaptic alterations. White matter pathology manifests as demyelination and axonal degeneration. Associated thiamine deficiency produces characteristic lesions in the mammillary bodies, thalamus, and cerebellar vermis. Neuroimaging techniques provide valuable HP correlates and biomarkers for disease monitoring. While some changes demonstrate partial reversibility with abstinence through remyelination and synaptic plasticity, extensive neuronal loss remains irreversible. Understanding these mechanisms is essential for developing neuroprotective therapeutic strategies.\n\nID: 42400823\nTitle: Update on Genetic Chorea.\nAbstract: Chorea is a symptom of numerous pathophysiologically and clinically heterogeneous genetic conditions.

Several novel genetic conditions have been linked to chorea over the last 3 years, including mutations in FTH1, NAA60, ACBD6 or TOR1AIP2. Also, novel phenotypes have been established and linked to chorea, such as Adult-onset Neurodegeneration in Nucleotide Excision Repair Disorder (NERD-ND). Major advances have been made in understanding of the pathophysiological role of somatic instability in HD. Striatal pallidal neurons (SPNs) with 150-500\u2009+\u2009CAG repeats seem to lose positive and then negative features of neuronal identity, de-repress senescence/apoptosis genes, ultimately leading to cell death. Improved recognition of the genetic background of chorea leads to more effective diagnostic processes, better prognostication and improved personalized treatment. The findings on somatic instability in HD suggest that neurodegeneration in HD is an asynchronous DNA process for >95% of a neuron's life, with majority of neurons in all disease stages having a HTT gene which is not biologically harmful. This has potential major therapeutic implications not only in HD but also in other neurological repeat expansion disorders.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42400671\nTitle: Correction: Non-canonical cell death in neurodegeneration: emerging mechanisms and therapeutic Frontiers.\nAbstract: \n\nID: 42398881\nTitle: Mitochondrial Dysfunction and Diabetic Retinopathy: Research Progress from Pathogenic Mechanisms to Therapeutic Targets.\nAbstract: Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes mellitus (DM) and remains a major cause of visual impairment and blindness in adults. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.\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: 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 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), 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 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, 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: 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: 42383006\nTitle: Dysregulation of sphingolipid-metabolizing enzymes in Friedreich's ataxia: In vitro and in vivo insights into therapeutic targeting.\nAbstract: Friedreich's ataxia (FRDA) is an inherited neurodegenerative disorder caused by a GAA repeat expansion within the FXN gene, leading to reduced frataxin levels. This deficiency results in mitochondrial dysregulation, oxidative stress, and progressive cell death. Currently, only one approved treatment exists for FRDA in the United States, Canada, and the European Union, which improves neurological outcomes but has not been fully evaluated for broader disease symptoms. Therefore, identifying new therapeutic targets remains essential. Sphingolipids are increasingly recognized for their roles in neurodegeneration with emerging evidence indicating their dysregulation in FRDA. Here, we investigate whether sphingolipid-metabolizing enzymes are similarly affected and assess the therapeutic potential of targeting them. Our findings demonstrate that these enzymes are dysregulated across multiple FRDA models. Importantly, their modulation in vitro and in vivo significantly reduces mitochondrial dysfunction, enhances frataxin expression, and improves key pathological features of the disease, highlighting sphingolipid metabolism as a promising therapeutic target for FRDA.\n\nID: 42381015\nTitle: Genetically predicted CXCL16 expression is associated with Parkinson's disease risk and peripheral immune cell dysregulation: a two-sample mendelian randomization study.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder with limited disease-modifying therapies. PANoptosis, an integrated form of programmed cell death involving apoptosis, pyroptosis, and necroptosis, has been implicated in neuroinflammation-related neurodegeneration. However, the roles of PANoptosis-related genes in PD remain unclear. We performed two-sample Mendelian randomization (MR) using cis-eQTL instruments from the eQTLGen Consortium for 30 PANoptosis-related genes, with PD GWAS data from Nalls et al. 2019 as the outcome. Instrumental variables were selected using a hierarchical strategy, with genome-wide significant cis-eQTLs as primary instruments and a relaxed threshold applied only for genes with fewer than three independent SNPs. Sensitivity analyses included MR-Egger, weighted median, MR-PRESSO, MR-RAPS, and leave-one-out analyses. SMR/HEIDI testing and two-step MR mediation using 731 peripheral immune traits were also performed. Genetically predicted higher CXCL16 expression was associated with increased PD risk (OR\u2009=\u20091.115, 95% CI 1.060-1.173, p\u2009=\u20092.4\u2009\u00d7\u200910-5), while higher FADD expression was associated with reduced PD risk (OR\u2009=\u20090.861, 95% CI 0.790-0.939, p\u2009=\u20097.1\u2009\u00d7\u200910-4). CASP1 and IFI27 were nominally significant and considered exploratory. Sensitivity analyses were directionally consistent, although MR-Egger estimates were imprecise. SMR/HEIDI supported CXCL16. Exploratory mediation analysis identified 63/66 candidate immune mediators after FDR correction. These findings provide MR-based genetic evidence linking CXCL16 expression to PD risk, with exploratory mediation through peripheral immune phenotypes. The CXCL16-immune cell-PD axis warrants further experimental validation.\n\nID: 42380289\nTitle: SARM1 base-exchange inhibitors induce SARM1 activation and neurodegeneration at low doses.\nAbstract: SARM1 has emerged as a promising therapeutic target in neurology due to its central role in axonal degeneration and its amenability to different modes of small molecule inhibition. One chemical approach to modulate SARM1 involves orthosteric inhibition via a SARM1-mediated base-exchange reaction between a small molecule and nicotinamide adenine dinucleotide (NAD+), the substrate of SARM1, to generate the active inhibitor. Here, we report that subinhibitory concentrations of SARM1 base-exchange inhibitors (BEIs) paradoxically increase SARM1 activity and worsen SARM1-induced cell death and neuronal damage in vitro. Low dose administration of RO-7529, a SARM1 BEI, exacerbated experimental autoimmune encephalomyelitis (EAE)-induced neurodegeneration in vivo. Our data highlight a unique pharmacological feature of SARM1 BEIs that may limit their therapeutic application in disorders associated with SARM1 activation and axonal degeneration.\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: 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: 42362957\nTitle: Decoding PANoptosis: Crosstalk of cell death pathways in immunity and inflammation.\nAbstract: PANoptosis is an emerging regulated cell death that integrates the molecular machinery of apoptosis, necroptosis, and pyroptosis into a combined, highly coordinated process. Defined as a distinct, integrative form of cell death, PANoptosis simultaneously engages these three pathways through a multiprotein scaffold known as the PANoptosome, ensuring robust elimination of infected, damaged, or transformed cells. Initially described in response to viral infections, PANoptosis is now recognized as a critical regulator of immune defense, inflammation, and tissue homeostasis, with broad implications for infectious diseases, cancer, autoimmune disorders, neurodegeneration, and ischemia-reperfusion injury. This review provides a comprehensive overview of the molecular composition of the PANoptosome, key triggers of PANoptosis, and its morphological and biochemical hallmarks. We further discuss its dual roles as both a protective and pathogenic mechanism, highlighting context-dependent contributions to host defense and disease progression. Finally, we examine therapeutic opportunities, including small-molecule inhibitors and gene-editing approaches, and outline current challenges, such as the identification of reliable biomarkers and the need for precision-targeted strategies. By integrating recent advances, this review highlights PANoptosis as a conceptual shift in cell death biology and a promising avenue for novel interventions in inflammation-driven diseases.\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: 42353197\nTitle: Hesperetin Rescues Amyloid Beta-Induced Defects in Neurite Outgrowth Under In Vitro Mild Cognitive Impairment-like Cellular Conditions.\nAbstract: Accumulation of aggregated amyloid beta (A\u03b2) species is a defining pathological hallmark of Alzheimer's disease and is associated with extensive neuronal structural abnormalities. Mild cognitive impairment (MCI), a transitional stage between normal aging and the onset of dementia, is thought to represent an early phase of this pathological continuum. Studies at the cellular level suggest that the conditions impair the maintenance of established neuronal processes/networks and restrict their capacity for elongation or re-elongation. They may also attenuate the activation and process extension of quiescent neural progenitor or stem-like cells. These early cellular changes precede overt neurodegeneration in neural tissue and are likely to contribute to cognitive decline. They highlight the importance of in vitro models for identifying molecular targets involved in recovery from disease. In this study, we investigated the effects of aggregated A\u03b2 (25-35) on neuronal process elongation and associated intracellular events in the N1E-115 cell line, a widely used model of neuronal differentiation. Addition of aggregated A\u03b2 to cultured N1E-115 cells attenuated process elongation in a concentration-dependent manner. This morphological impairment was accompanied by decreased expression of neuronal differentiation markers. In contrast, at the half-maximal inhibitory concentration for process elongation, long-term cultured cells did not exhibit apparent process retraction or degenerative morphology. This mild but progressive impairment, without extensive cell death, is consistent with the cellular features of early-stage conditions rather than advanced Alzheimer's pathologies. Similar results were observed in primary cortical neurons. A\u03b2 also decreased the level of GTP-bound Ras and phosphorylation of the downstream mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK). Furthermore, treatment with hesperetin, a bioactive flavonoid compound, recovered the A\u03b2-induced inhibition of neuronal process elongation. Hesperetin also restored Ras and MAPK/ERK states, suggesting that its effects are associated, at least in part, with modulation of signaling through Ras and MAPK/ERK. Our findings suggest that hesperetin may serve as a useful molecular probe for modulating early cellular responses associated with Alzheimer's disease-related pathology. This in vitro model might serve as a useful platform for investigating the molecular target candidates involved in recovery from nervous system disorders.\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: 42352319\nTitle: Protein Palmitoylation as a Molecular Switch Linking Regulated Cell Death and Disease.\nAbstract: Regulated cell death is essential for tissue homeostasis, immune defense, and disease progression, yet the lipid-based regulatory mechanisms that coordinate cell death signaling remain incompletely understood. Protein palmitoylation is a dynamic and reversible lipid post-translational modification that controls protein membrane association, trafficking, stability, and signaling complex assembly. This review summarizes the regulatory roles of palmitoylation and depalmitoylation in major forms of regulated cell death, including apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagy-related cell death. Particular attention is given to representative palmitoylated substrates, including Fas cell surface death receptor (Fas), receptor-interacting protein kinase 1 (RIPK1), NLR family pyrin domain containing 3 (NLRP3), gasdermin D (GSDMD), glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), autophagy-related 16 like 1 (ATG16L1), and Beclin1. These substrates illustrate how palmitoylation links membrane organization, metabolic status, inflammatory signaling, and cell fate decisions. Disease-oriented evidence further indicates that dysregulated palmitoylation contributes to cancer, neurodegenerative diseases, and inflammatory or immune-related disorders by modulating cell death resistance, inflammatory amplification, immune evasion, or impaired proteostasis. Current challenges include limited quantitative information on palmitoylation dynamics, incomplete evidence for some enzyme-substrate relationships, and insufficient distinction between disease-driving and secondary palmitoylation events. Targeting zinc finger Asp-His-His-Cys (zDHHC) palmitoyl acyltransferases, depalmitoylating enzymes, or specific palmitoylated substrates may provide new therapeutic opportunities. Overall, this review positions protein palmitoylation as a dynamic molecular switch linking lipid metabolism, membrane signaling, regulated cell death, and disease remodeling.\n\nID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\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: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.\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: 42345513\nTitle: Battling Parkinson's and Alzheimer's: The Neuroprotective Power of Carnosic Acid.\nAbstract: Neurodegenerative disorders have recently emerged as one of the most difficult worldwide health challenges. Neuronal cell injury is a major factor in neurodegenerative diseases. There seems to be rising interest in developing effective neuroprotective drugs from natural sources. Nutraceuticals, or compounds produced from natural sources have shown neuroprotective effects in both in vitro and in vivo models of neuronal cell death and neurodegeneration. Carnosic acid (CA), a natural compound majorly obtained from rosemary and other herbs, has emerged as a promising neuroprotective agent in neurodegenerative diseases, particularly Alzheimer's and Parkinson's. This review covers the latest findings on the methods by which carnosic acid mitigates key pathological features such as oxidative stress, neuroinflammation, apoptosis, and protein aggregation as well as other pathways related to Parkinson's and Alzheimer's disease induction. Furthermore, we describe preclinical and clinical research that demonstrates the ability of carnosic acid to improve cognitive function and motor performance. This study will give a detailed overview of carnosic acid as a possible therapeutic agent, opening the path for future research into viable therapies for Alzheimer's and Parkinson's disorders.\n\nID: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology.\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: 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: 42332177\nTitle: Trace Elements Dyshomeostasis and Toxic Metals Neurotoxicity in Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, are defined by the progressive loss of neurons through interconnected pathological mechanisms, including oxidative stress, mitochondrial dysfunction, protein aggregation, and neuroinflammation. Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases.\n\nID: 42331789\nTitle: PARylation in Parkinson's disease: a bridge between Lewy body formation and neuronal cell death.\nAbstract: Poly-ADP-ribosylation (PARylation), catalyzed by the enzyme PARP1, involves the addition of poly-ADP-ribose polymers (PAR) and has been associated with \u03b1-synuclein aggregation in Parkinson's disease (PD) models. This study aimed to unravel the role of PARylation in \u03b1-synuclein aggregation and neuronal cell death in the complex environment of post-mortem human PD brains. Using high-resolution imaging and 3D reconstruction analysis, we observed that PAR accumulate in the cytoplasm in regions affected by PD pathology, preceding the formation of \u03b1-synuclein oligomers. Additionally, we found that PAR and stress granules contribute to the formation of Lewy bodies. Increased colocalization of PAR with mitochondria in the substantia nigra of PD patients, along with the presence of PAR-positive condensed DNA, further suggests a role in neuronal cell death. Collectively, our findings reveal a critical involvement of PARylation in the pathological mechanisms underlying neurodegeneration in PD and position PARylation as a potential therapeutic target.\n\nID: 42327318\nTitle: Mutant SOD1 expressed by oligodendrocytes aggregates in myelinic nanochannels and accelerates disease progression in familial ALS mice.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a highly debilitating and fatal disease characterized by the progressive loss of motor neurons. Reduced oligodendroglial support has been implicated in ALS progression but remains mechanistically unexplained. Here, using a mutant superoxide dismutase 1 (SOD1-G37R) mouse model of familial ALS, Cre-mediated excision of the mutant SOD1 gene within the oligodendrocyte lineage prior to myelin compaction is shown to slow disease onset, improve motor performance, and prolong survival. In contrast, silencing mutant SOD1 expression within oligodendrocytes after myelin compaction failed to ameliorate disease phenotype. Electron microscopy is used to identify aggregation of mutant SOD1 within paranodal loops and the inner periaxonal tongue of 'myelinic nanochannels', narrow cytosolic compartments for the diffusion of metabolites and motor-driven transport processes. In a second mouse model (SOD1-G93A) of familial, SOD1 mutant-mediated ALS, we show that induction of excessive myelin compaction and myelinic channel collapse (by depletion of CNP from myelin) accelerates disease and diminishes survival. Our data support loss of myelinic channel integrity as a contributor to familial ALS disease initiation and progression, findings likely relevant to neurodegenerative disease involving other aggregation prone proteins that are expressed in myelinating oligodendrocytes. Oligodendrocytes have been implicated in the progression of amyotrophic lateral sclerosis (ALS) but the underlying mechanisms have remained obscure. Here we show in genetic mouse models that the familial ALS causing isoform of a ubiquitously expressed mutant enzyme (SOD1) aggregates in cytosolic channels within myelin that are responsible for delivery of transporters and nutrients necessary to support the axonal compartment. ALS disease progression was accelerated in mice when myelinic channels were collapsed by deleting CNP, a structural protein necessary for myelinic channel maintenance. Disruption of transport through myelinic channels by aggregation of mutant SOD1 may perturb oligodendrocyte support of motor axons and contribute to disease in this form of ALS.\n\nID: 42327312\nTitle: Spatial Transcriptomics reveals a T cell-mediated microglial activation axis of neurodegeneration following immune checkpoint inhibition.\nAbstract: Immune checkpoint inhibitor (ICI) combinations that block cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1) signaling have revolutionized cancer care but also exert a range of immune-related adverse events (irAE) in various tissues, including the brain. Our understanding of the mechanisms of irAE in the brain is still evolving, and we recently demonstrated that ICI (blockade of CTLA-4 and PD-1) perturbs hippocampal-dependent memory function by derailing neuro-immune homeostasis and compromising synaptic integrity. However, the spatial patterns and the cell-type-specific molecular mechanisms underlying ICI-related brain dysfunction remain not well-defined. To address this gap, we performed spatial transcriptomic profiling of the hippocampal region using multiplexed error-robust fluorescence in situ hybridization (MERFISH) to map gene expression at single-cell resolution. By integrating spatial single-cell data with bulk RNA-seq, we define the distribution of microglia, astrocytes, synaptic, and neuroinflammatory markers, and determine how ICI reshapes hippocampal cellular composition in a syngeneic murine melanoma model. MERFISH revealed upregulation of microglial, astrocytic, oligodendrocytic, and T cell markers post-ICI treatment, revealing unique pathways driving neuroinflammation, synaptic function, and cellular signaling. Furthermore, immunofluorescence analysis of postmortem brains from patients treated with ICI corroborates our findings of ICI-related immune activation of microglia. Finally, using a conditional deletion model, we show that T cells are indispensable for ICI-driven microglial activation. Altogether, our study provides a high-resolution spatial framework for understanding irAEs in brain function and a T cell-microglia crosstalk axis as a driving mechanism of dysregulated neuro-immune homeostasis during ICI.\n\nID: 42416408\nTitle: The SGLT2i \"canagliflozin\" and the DPP-4i \"sitagliptin\" mitigate hypertensive nephropathy in adult male rats by modulating the Ang II/RAGE/Nox4/NLRP3 cascade.\nAbstract: Hypertensive nephropathy (HN) with progressive renal damage is a common consequence of arterial hypertension (HTN). This study addresses the renoprotective attributes of the sodium-glucose cotransporter-2 inhibitor canagliflozin (Cana) and the dipeptidyl peptidase-4 inhibitor sitagliptin (Sita) on HN. Twenty-four adult male Wistar rats were categorized into four groups (six per group): control (CTRL), hypertensive nephropathy (HN); rats were given L-NAME (50 mg/kg, i.p., once a day), HN + Cana; rats were given L-NAME injections alongside oral Cana 10 mg/kg, and HN + Sita; rats were provided Sita 10 mg/kg concurrently with L-NAME injection. All regimens were given once a day for five consecutive weeks. Various physiological, biochemical, molecular, and histological parameters were evaluated. Administration of Cana and Sita alleviated HN, as demonstrated by the notable improvements in renal functions, plasma angiotensin II, and systolic blood pressure. Additionally, a noticeable improvement in renal superoxide dismutase, malondialdehyde, NOD-like receptor family pyrin domain containing 3 inflammasome, interleukin (IL)-1\u03b2/-10, caspase 1, advanced glycation end products (AGEs), and relative expression of receptors for AGEs and nicotinamide adenine dinucleotide phosphate oxidase 4 was detected. Substantial enhancement in the microscopic structure of renal tissues, attenuated renal fibrosis, and decreased immunoreactivity of BAX and tumor necrosis factor-\u03b1 highlighted these protective attributes. Both Sita and Cana successfully attenuated HTN and subsequent HN, thereby restoring renal function; however, Sita's protective profile was more favorable. These results implied that Sita and Cana might provide renoprotective impacts for kidney damage triggered by HTN in rats. However, additional research to investigate their possible modes of action is necessary.\n\nID: 42414763\nTitle: Atraric acid enhances neuronal survival and cognition against D-galactose-induced neurodegeneration via BDNF/TrkB/AKT signaling.\nAbstract: Aging-induced neurodegeneration is characterized by cognitive impairment, elevated oxidative stress, neuroinflammation, synaptic loss, and neuronal death. Atraric acid (AA), a phenolic compound obtained from lichens, is reported to have potent anti-inflammatory and antioxidant effects in various disease models. However, aging-induced cognitive impairment and dementia are still not elucidated. To fill this gap, we investigated AA (20\u00a0mg/kg/day, intraperitoneally (i.p.) for 4\u00a0weeks) against D-galactose (D-gal) (120\u00a0mg/kg/day, i.p. for 8\u00a0weeks)-induced brain senescence and memory dysfunction in mice. Behavioral tests, including NOR, MWM, and Y-maze, were conducted to assess cognitive function, followed by biochemical and immunofluorescence analyses. AA restored the BDNF/TrkB/Akt signaling axis disrupted by D-gal administration. Furthermore, immunoblotting for Nrf-2 and HO-1 revealed elevated expression in the mouse cortex and hippocampus. AA also enhanced antioxidant enzymes, including glutathione (GSH), glutathione S-transferase (GST), catalase (CAT), and superoxide dismutase (SOD), while reducing lipid peroxidation (LPO), thereby supporting its antioxidant role. Moreover, D-gal enhanced NF-kB-mediated neuroinflammation, apoptotic markers including caspase-3 and PARP-1, and suppressed synaptic proteins (SNAP-23 and PSD-95). Interestingly, these expression aberrations were reversed upon AA administration. Histological analyses using Nissl and Fluoro-Jade B staining further supported neuronal protection in the cortex and hippocampus. Collectively, these findings suggest that AA exerts neuroprotective effects against D-gal-induced aging and cognitive decline by reducing oxidative stress, neuroinflammation, neuronal apoptosis, and enhancing synaptic plasticity through BDNF/TrkB/Akt/CREB signaling.\n\nID: 42402988\nTitle: Agmatine Attenuates Methotrexate-Induced Hepatotoxicity: Targeting Oxidative Stress, Inflammation, and Apoptotic Pathways.\nAbstract: Drug-induced hepatic insult is the most frequent antecedent of liver dysfunction. The folic acid antagonist, Methotrexate (MTRX), has tremendous applications in the treatment of various tumors, autoimmune disorders, and inflammatory diseases, but hepatotoxicity limits its clinical use. This study aimed to investigate the role of AGM against MTRX-induced hepatotoxicity and its possible underlying mechanistic pathways. Mice were pre-treated with AGM (14\u2009mg/kg, orally) and administered a single injection of MTRX (20\u2009mg/kg, i.p.) on Day 6. MTRX-induced hepatic injury was evidenced by marked increase in serum hepatotoxicity markers, decreased hepatic reduced glutathione (GSH) level and superoxide dismutase (SOD) activity, and hepatic interleukin (IL)-10 content, besides increased levels of malondialdehyde (MDA), nitric oxide (NO), tumor necrosis factor-alpha (TNF-\u03b1), IL-6, c-Jun N-terminal kinase (JNK), BCL2-associated X protein (BAX), and Caspase-3. Moreover, MTRX increased hepatic expression of nuclear factor kappa-B (NF-\u03baB), and inducible nitric oxide synthase (iNOS), AGM pretreated group revealed a substantial elevation in hepatic antioxidant markers, besides marked reduction in the serum levels of hepatotoxicity markers and hepatic content of MDA, NO, NF-\u03baB, TNF-\u03b1, IL-6, iNOS, JNK, BAX, and Caspase-3. Furthermore, the protective effect of AGM was affirmed by liver histological examination. Therefore, AGM attenuates MTRX's liver injury by mitigating oxidative stress, inflammation, and apoptosis. These findings suggest that AGM could be considered as a potential adjuvant in MTRX-induced toxicity.\n\nID: 42369229\nTitle: BMX-001 acts as a selective chemoradioprotector in rectal cancer.\nAbstract: Colorectal cancer is a common yet survivable malignancy, partly due to the addition of chemoradiation to treatment regimens. Many patients suffer treatment-related side effects such as pain, diarrhea, and myelosuppression, and increasing tolerance of treatment has the potential to improve outcomes. BMX-001, a superoxide dismutase mimetic, is currently in clinical trials as a selective radioprotector for anal and rectal cancer; however, the mechanism by which BMX-001 exerts selective radioprotection of healthy tissue over cancer tissue, particularly when administered at physiologically achievable doses, is not well understood. BMX-001 was given before and during chemoradiation and did not interfere with chemoradiation-induced cancer cell killing in mouse models. In vitro, BMX-001 still induced cancer cell killing in the presence of exogenous catalase, suggesting that BMX-001's anti-tumor activity is not solely reliant on hydrogen peroxide production. BMX-001 exerted robust acute radioprotection in radiation mouse models five and nine days post-radiation. To assess whether BMX-001's protection is contingent on Nrf2 expression, we evaluated the effect of BMX-001 on 5-FU treated mouse bone marrow, where Nrf2 is crucial to maintaining hematopoietic stem cell niches. Interestingly, BMX-001 could still exert some chemoprotection in mice without functional Nrf2. To assess whether BMX-001 had any functional effects on protein oxidation status, we performed mass spectrometry analysis to evaluate sulfenylated proteins in bone marrow treated with 5-FU in wildtype mice and mice without Nrf2. We found that BMX-001 given before 5-FU treatment resulted in the sulfenylation of CRTC2 and CBP, two proteins involved in CREB signaling and known to enhance Nrf2 activity. We also found that BMX-001 with 5-FU treatment enhanced DPYD sulfenylation, a protein known to detoxify 5-FU, and ALDH7A1 sulfenylation, a protein known to detoxify aldehydes. Together, these results suggest that BMX-001 can protect against oxidative stress in normal tissue via Nrf2 dependent and independent mechanisms.\n\nID: 42361413\nTitle: Colchicine attenuates diet-induced early aortic vascular remodeling in mice via modulation of inflammatory and cell death-associated pathways.\nAbstract: Atherosclerosis (AS) contributes to cardiovascular diseases (CVDs) through inflammation and oxidative stress, with inflammation-associated cell death pathways as drivers of vascular injury. This study aimed to investigate the protective effects of colchicine on diet- induced vascular remodeling, focusing on caspase-1-dependent inflammatory signaling, caspase-3/gasdermin E (GSDME)-mediated cell death pathways, and toll-like receptor 4 (TLR4) signaling modulation. Forty adult male C57BL/6 mice were categorized into four groups: control, colchicine-treated (0.25\u202fmg/kg/day, i.p.), hypercholesterolemic, and hypercholesterolemic plus colchicine (0.25\u202fmg/kg/day, i.p.). Mice were sacrificed after 12 weeks, and blood samples were collected. Thoracic aortic specimens were prepared for subsequent biochemical, molecular, histological, and ultrastructural analysis. Colchicine administration significantly improved serum lipid profiles and modulated tissue oxidative stress by decreasing (1.8-fold) malondialdehyde (MDA) levels and increasing (1.75-fold) superoxide dismutase (SOD) levels. Colchicine significantly downregulated the mRNA expression levels of caspase-1 (2.4-fold), interleukin-1 beta (IL-1\u03b2) (3.6-fold), specificity protein 1 (SP1) (3.0-fold), signal transducer and activator of transcription 3 (STAT3) (2.4-fold), GSDME (3.3-fold), and TLR4 (2.6-fold) in the aortic samples, accompanied by near-normal immunohistochemical expression of caspase-3 and IL-1\u03b2. Furthermore, colchicine effectively preserved aortic wall structure, diminished fibrosis, and attenuated ultrastructural damage associated with inflammatory cell death. Colchicine displays protective effects against diet-induced vascular remodeling in mice, associated with the modulation of inflammatory and cell death pathway markers, alongside ultrastructural improvements. These findings support its therapeutic potential for mitigating vascular injury relevant to atherosclerosis, though further mechanistic validation is required.\n\nID: 42359160\nTitle: Repurposing the Antibiotic Tigecycline to Inhibit Tumor Growth and Hormone Secretion in Somatotroph Pituitary Neuroendocrine Tumors.\nAbstract: This investigation employed the rat GH3 somatotroph pituitary neuroendocrine tumor (PitNET) cell line to assess the effects of the antibiotic tigecycline and to preliminarily elucidate its potential molecular mechanisms. GH3 cells were exposed to tigecycline ranging from 6.25 to 100\u2009\u03bcM. Cell viability and IC50 were determined using the CCK-8 assay, and spheroid growth was monitored by measuring diameters. To assess apoptosis, cells were subjected to Annexin V-FITC/PI staining and nuclear morphology observation after DAPI staining. Meanwhile, the cell cycle distribution was profiled via flow cytometry following propidium iodide (PI) staining. The expression of proteins related to the Akt/mTOR pathway, apoptosis, and growth hormone (GH) was evaluated by Western blot. GH secretion was quantified using ELISA. Tigecycline dose and time dependently suppressed GH3 cell proliferation, with IC50 values of 22.45\u2009\u03bcM at 48\u2009h and 9.037\u2009\u03bcM at 72\u2009h. It also impeded three-dimensional spheroid growth. Mechanistically, treatment induced G0/G1 phase arrest, significantly suppressed the Akt/mTOR signaling pathway (evidenced by reduced phosphorylation of Akt and mTOR), and activated the intrinsic apoptotic pathway, marked by a rise in the Bax/Bcl-2 ratio and heightened cleaved caspase-3 expression. Additionally, tigecycline significantly attenuated both intracellular synthesis and extracellular secretion of GH. These findings indicate that tigecycline exerts potent antiproliferative and antisecretory effects on GH3 cells, likely through Akt/mTOR pathway inhibition, cell cycle arrest, and apoptosis induction. These results provide an experimental foundation for considering tigecycline as a potential therapeutic agent for GH-secreting PitNET.\n\nID: 42358374\nTitle: Comparative neuroprotective and exercise capacity effects of prophylactic intermittent fasting and probiotics in sleep-deprived rats: insights into anti-inflammatory marker modulation and CLOCK gene regulation.\nAbstract: Prophylactic probiotics and intermittent fasting (IF) substantially modulate the neuropsychological functions and exercise capacity in rats subjected to sleep deprivation (SD). A comparative study was conducted to analyze the effects of probiotics and IF on SD-induced neuropsychological disturbances and compromised muscle endurance. Forty albino Wistar rats were randomly assigned to four groups. The NSD group was maintained on a standard chow diet for 12\u00a0weeks. The SD group followed an SD regimen for 72\u00a0h per week over 8\u00a0weeks, starting from the fifth week. The SDP group received probiotics at a dose of colony-forming units (CFUs)/100\u00a0g/day for 4\u00a0weeks prior to SD, followed by 8\u00a0weeks of concurrent probiotic administration with SD. The SDIF group underwent an alternate-day fasting regimen for 4\u00a0weeks before SD, followed by 8\u00a0weeks of simultaneous SD combined with IF. Neuropsychological functions and exercise capacity were tested, and then the brains were carefully dissected, sectioned, and processed for hematoxylin and eosin, cresyl violet, and immunohistochemical staining. Inflammatory markers, including interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1), and hippocampal expression of the circadian locomotor output cycles kaput (CLOCK) gene, were significantly elevated in the SD group. Conversely, it showed significant decreases in endurance, exploratory behavior, hippocampal superoxide dismutase (SOD) activity, and fecal short-chain fatty acids (SCFAs). Histological analysis also revealed hippocampal gliosis, apoptosis, CA1 pyramidal cell degeneration, layer disorganization, and upregulation of glial fibrillary acidic protein (GFAP), NF-\u03baB, and cleaved caspase-3. Nevertheless, both probiotics and IF markedly reduced serum MDA, hippocampal CLOCK gene expression, gliosis, and apoptosis and enhanced memory performance. In addition, they significantly increased hippocampal SOD activity and SCFAs. These findings indicate that prophylactic probiotics decrease cognitive disruption and impaired muscle endurance caused by SD through CLOCK gene regulation compared to that with IF. This highlights the need for further research to elucidate these mechanisms. Histological findings also supported these results, showing improved neuronal structure in the hippocampus following probiotic treatment.\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: 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: 42257417\nTitle: Investigating the hepato-nephroprotective effects of deferoxamine in lead-induced toxicity of rats.\nAbstract: Lead is a well-known toxic heavy metal with detrimental effects on various tissues and organs. Chelation therapy remains the principal therapeutic strategy for reducing lead toxicity through enhancement of metal elimination from blood and tissues. Deferoxamine (DFO), an iron chelator, has demonstrated protective effects against multiple heavy metals. This study evaluates the hepatoprotective and nephroprotective effects of DFO following lead-induced toxicity in Wistar rats. Six groups were studied: a control group receiving 2\u2009mL/kg of normal saline, and five lead-exposed groups (40\u2009mg/kg lead acetate for one week) treated with saline, DFO (200\u2009mg/kg), DFO (400\u2009mg/kg), EDTA (50\u2009mg/kg), or a combination of DFO (400\u2009mg/kg) and EDTA (50\u2009mg/kg) for one-week post-poisoning. Oxidative stress markers, cell viability, DNA damage, and histopathological changes in liver, kidney, and blood samples were assessed. The results demonstrated that DFO alone or in combination with EDTA significantly reduced oxidative stress, improved antioxidant enzyme levels (glutathione, catalase, and superoxide dismutase), decreased malondialdehyde levels, minimized DNA damage, and enhanced cell viability compared to untreated lead-poisoned rats. Histological analysis corroborated these findings, showing marked tissue protection. DFO at 400\u2009mg/kg, alone or combined with EDTA, showed the strongest protection against lead-induced hepatotoxicity and nephrotoxicity.\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: 42191406\nTitle: Eugenol enhances the in vitro maturation of dromedary camel oocytes.\nAbstract: During in vitro embryo production, oxidative stress can compromise oocyte competence and subsequent embryo development. Phenolic antioxidants derived from plants, including eugenol (EG), represent a promising strategy to reduce the detrimental effects of reactive oxygen species (ROS) accumulation and improve embryo development outcome. This study investigated the concentration-dependent effects of EG on the in vitro maturation (IVM) of dromedary camel cumulus-oocyte complexes (COCs). COCs were cultured in IVM medium containing 0 (control), 10, 20, 40, and 80\u00a0\u03bcM EG. Supplementation with 10 or 20\u00a0\u03bcM EG significantly increased oocyte maturation rates compared with control, whereas supplementation with 40 or 80\u00a0\u03bcM EG provided no additional benefit. Immunofluorescence analysis showed that all EG-treated groups exhibited a significant increase in lipid content and mitochondrial activity. However, the effect was significantly greater at 10 and 20\u00a0\u03bcM. Assessment of the spent IVM media showed that superoxide dismutase (SOD) and catalase (CAT) levels were significantly increased at 20\u00a0\u03bcM EG, while malondialdehyde (MDA) levels were reduced at 10 and 20\u00a0\u03bcM relative to the control. Additionally, cumulus cells recovered from oocytes matured with 10 and 20\u00a0\u03bcM EG displayed increased transcript levels of BCL2, CAT, IGF1, and SOD1 genes. Collectively, these findings indicate that EG at 10 and 20\u00a0\u03bcM may enhance IVM of camel oocytes by promoting nuclear maturation, cumulus expansion, mitochondrial activity, and lipid accumulation, accompanied by increased transcript levels of BCL2, CAT, IGF1, and SOD1.\n\nID: 42185681\nTitle: The possible effects of folic acid and postbiotic yeast on doxorubicin-induced cardiotoxicity in rats: interactions among the gut microbiota, antioxidants, and NLrp3 activities.\nAbstract: Doxorubicin (DOX) cardiotoxicity is a common adverse effect and is dose dependent. Folic acid (FA) and E-yeast (a deactivated form of Saccharomyces cerevisiae combined with wheat germ oil) are natural dietary supplements that may help mitigate these adverse effects. To compare the cardioprotective, antioxidant, anti-inflammatory, histological, and gut microbiota-modulating effects of FA and E-yeast on DOX-induced cardiac toxicity in rats. Twenty-four rats were divided into four groups: control, DOX-treated, FA\u2009+\u2009DOX, and E-yeast\u2009+\u2009DOX. The cardiac biomarkers lactate dehydrogenase and creatine kinase-MB (LDH, CK-MB), oxidative stress markers (malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPX), inflammatory mediators (IL-6, TNF-\u03b1, IFN-\u03b3, NLrp3), and fecal short-chain fatty acids (SCFAs) (acetic, butanoic, and propionic acids) were measured. In addition, left ventricular echocardiography and cardiac and colonic histology, including cardiac NADPH oxidase 4 (NOX4) expression, were assessed. DOX induced cardiac dysfunction, as shown by increased cardiac enzymes, left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic diameter (LVEDD) and decreased ejection fraction and SCFAs. Additionally, it increased the levels of MDA, IL-6, TNF-\u03b1, IFN-\u03b3, and NLrp3. Folic acid restored cardiac, echocardiographic, oxidative, and inflammatory parameters to normal levels, whereas E-yeast only partially improved these parameters. SCFAs were restored to normal by both treatments. Histologically, DOX caused cardiomyocyte degeneration, necrosis, and increased NOX4 expression, resulting in degenerative disruption of the colonic mucosa. Folic acid was more effective at preserving the myocardial architecture and NOX4 expression, whereas E-yeast was more effective at minimizing colonic degenerative lesions. Folic acid demonstrated a more pronounced healing effect than did E-yeast on DOX-induced cardiac alterations.\n\nID: 42177838\nTitle: Obesity suppresses neutrophil-dependent itaconate signaling promoting ferroptosis in acute pancreatitis.\nAbstract: Obesity is a well-established risk factor for increased severity and mortality in acute pancreatitis. However, the mechanisms by which obesity alters pancreatic immune regulation and favors the progression of acute pancreatitis are not elucidated yet. Here, we identify a neutrophil-driven immune-metabolic pathway that controls ferroptosis during pancreatic inflammation. We show that infiltrating myeloid cells represent the principal source of the immunometabolite itaconate during acute pancreatitis. Through paracrine transfer via the SLC13A3 transporter, myeloid-derived itaconate protects pancreatic acinar cells from ferroptosis by sustaining NRF2-dependent antioxidant responses. Obesity disrupts this protective axis by suppressing ACOD1 expression in infiltrating neutrophils. Proteomic profiling of pancreatic neutrophils from obese mice confirmed reduced ACOD1 abundance and decreased expression of enzymes linked to the tricarboxylic acid cycle and pyruvate metabolism. This metabolic reprogramming limits itaconate production and weakens NRF2-driven redox defenses, leading to downregulation of the xCT-GPX4 ferroptosis-protective pathway and increased lipid peroxidation in the pancreas of obese mice with pancreatitis. Pharmacological restoration of itaconate signaling with the cell-permeable derivative 4-octyl itaconate reactivates NRF2 signaling, the xCT-GPX4 antioxidant axis, and the trans-sulfuration pathway, mitigating pancreatic injury. Together, these findings identify neutrophil-derived itaconate as a key modulator of ferroptosis susceptibility and reveal immune cell metabolism as a critical determinant of obesity-associated severity in acute pancreatitis.\n\nID: 42164935\nTitle: Hibiscus sabdariffa calyx extract induces anti-proliferative and anti-migratory effects in ovarian cancer.\nAbstract: Plant bioactives are necessary for human health owing to their many biological impacts. Hibiscus sabdariffa Linn calyx extract is known for its anti-inflammatory, antimicrobial, and antioxidant properties. Extracellular matrix 1 (ECM1) is a glycoprotein with distinct biological activities ranging from immunological to physiological roles. The impact of calyx extract on ECM1 in ovarian cancer has not been thoroughly investigated, particularly in cell proliferation inhibition and apoptosis. MTT assay was performed to determine anticancer activity in Rosella extract. The cell and nuclear morphology were examined along with colony formation, and migration assay. The effect of the extract on the molecules involved in the cell signaling mechanism was evaluated using western blotting and PCR. Calyx extract cytotoxicity presented by the MTT assay at a 2.8\u00a0mg IC50 value, with atypical nuclear morphology and reduced cell migration. Rosella crude extract influences ECM1 glycoprotein, AKT1, and Cyclin D1 suppressing colony-forming ability. Apoptosis gets triggered, resulting in upregulation of different caspases, BID, and suppression of Bcl-2. The Rosella crude extract inhibited cell growth in OVCAR3 cells regulating the ECM1/AKT1/Cyclin D1 pathway, suggesting a potential approach for treating ovarian cancer.

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: 42144025\nTitle: Lycopene, quercetin, and silymarin alleviate tartrazine-induced liver injury via modulating Nrf2 signaling and endoplasmic reticulum stress pathways.\nAbstract: Tartrazine is a synthetic lemon-yellow azo dye that is widely used as a coloring agent in food products, drugs, and cosmetics. Tartrazine was reported to induce hepatotoxicity, however, the effects of tartrazine on nuclear factor erythroid two-related factor two (Nrf2) signaling and endoplasmic reticulum (ER) stress pathways in rat liver have not been investigated. Therefore, this study aimed to investigate the effects of tartrazine on Nrf2 signaling and ER stress pathways in rat liver, to examine the potential therapeutic effects of lycopene, quercetin, and silymarin, and to investigate the mechanisms through which they may mitigate tartrazine-induced liver injury. Rats were allocated into five experimental groups including a normal control group and a tartrazine group that received tartrazine (10 mg/kg) orally for 13 weeks. The lycopene, quercetin, and silymarin groups received tartrazine (10 mg/kg) for 13 weeks and were treated with lycopene (10 mg/kg), quercetin (50 mg/kg), and silymarin (150 mg/kg), respectively, for the last 8 weeks. Tartrazine-induced liver injury was characterized by increased alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase serum levels and histopathological changes in the liver. Furthermore, tartrazine suppressed hepatic Nrf2 signaling and induced ER stress. Hepatic levels of malonaldehyde and caspase-3 were increased, while the levels of superoxide dismutase activity and glutathione and B cell lymphoma-2 were decreased. Moreover, hepatic transforming growth factor-beta one levels and collagen deposition were increased. Treatment with lycopene, quercetin, and silymarin ameliorated the tartrazine-induced changes, upregulated Nrf2 signaling and alleviated ER stress. Our findings suggest that lycopene, quercetin, and silymarin may provide a promising therapeutic approach against tartrazine-induced liver injury.\n\nID: 42128709\nTitle: MitoSafe hypothesis: safeguarding mitochondrial morphology and innate immunity.\nAbstract: Mitochondria divide and fuse, and the balance between these processes maintains mitochondrial morphology and function. Although the core fusion and division machinery is well established, how cells sense mitochondrial morphology and actively adjust it remains unclear. In this Opinion article, we propose a new conceptual framework, termed 'Mitochondrial Safeguard (MitoSafe)', in which cells monitor mitochondrial size and rebalance division and fusion through four branches: activation of fusion or inhibition of division in small mitochondria and activation of division or inhibition of fusion in enlarged mitochondria. Recent findings show that fusion is suppressed once mitochondria exceed a healthy size threshold. Dysregulation of this branch of MitoSafe, involving Parkin, PINK1, SLC25A3, SOD1, and cytochrome-c oxidase, causes mitochondrial enlargement, mitochondrial DNA release, and stimulator of interferon genes (STING)-mediated inflammation.\n\nID: 42120462\nTitle: Hyaluronic acid/kaempferol-functionalized Fe\u2083O\u2084 nanoparticles promote ROS-associated apoptosis and modulate caspase-8/BCRT1 axis in triple-negative breast cancer.\nAbstract: Hyaluronic acid receptor targeting is an innovative approach in cancer treatment. This work aims to characterize anticancer properties of Fe3O4 nanoparticles functionalized with glucose and co-conjugated with hyaluronic acid (HA) and Kaempferol (KAE) in triple negative breast cancer (TNBC) cells. The Fe3O4@Glu-HA-KAE NPs were characterized by FT-IR, XRD, EDS, SEM, TEM, DLS and zeta potential analyses. Cytotoxicity in MDA-MB-231 cells was evaluated using MTT assays. Apoptosis and cell cycle changes were analyzed by flow cytometry, Nuclear morphology was examined via AO/PI staining, and ROS production was measured in treated and control groups The FT-IR, XRD and EDS analyses confirmed the correct synthesis of Fe3O4@Glu-HA-KAE NPs. The NPs were spherical with a particle size of 10-60\u00a0nm in their dried form and an average diameter of 276\u00a0nm and a surface charge of -39.7 mV. Fe3O4@Glu-HA-KAE NPs exhibited dose- and time-dependent toxicity against TNBC cells and the 24-hour and 48-hour IC50 of the NPs in the MDA-B-231 cells were 215 and 149\u00a0\u00b5g/mL, respectively. In addition, the NPs caused cell cycle arrest at the sub-G1 phase, and increased cell apoptosis percentage to 65.1-68.1%. The synthesized NPs triggered significant nuclear alterations, enhanced ROS generation, and elevated cell death in TNBC cells.Furthermore, exposure to Fe\u2083O\u2084@Glu-HA-KAE NPs led to a 1.41-fold increase in Caspase-8 expression, while BCRT1 lncRNA transcript levels were markedly reduced to 0.73-fold, indicating that apoptosis-related mechanisms contribute to the observed cytotoxicity. This work demonstrates efficient anticancer properties of Fe3O4@Glu-HA-KAE NPs against TNBC cells, representing an innovative approach to combat TNBC.\n\nID: 42119666\nTitle: FSH mediated endocrine disruption potential of Dibutyl phthalate in cultured ovine ovarian granulosa cells: Cytotoxicity, oxidative stress, steroidogenesis, cell senescence, and expression of related key developmental genes.\nAbstract: Di-n-butyl phthalate (DBP) is a widely used phthalate ester recognized for its endocrine-disrupting properties and potential reproductive toxicity. The present study aimed to evaluate the concentration-dependent effects of DBP on morphology, cytotoxicity, oxidative stress, cell senescence, steroidogenesis and expression of related key developmental genes in cultured ovine granulosa cells in the presence of FSH. Granulosa cells were isolated from slaughterhouse-derived ovine ovaries and cultured in vitro with exposure to DBP at concentrations of 0, 1, 10, 25, 50, and 100\u202f\u00b5M. Cytotoxic responses were assessed by evaluating nuclear damage, reactive oxygen species (ROS) generation, apoptosis, and cellular senescence. In addition, expression levels of key steroidogenic genes (CYP11A1, CYP17A1, CYP19A1, STAR, HSD3B1, HSD17B1), hormonereceptors (ESR1, ESR2, PGR, FSHR), and pro-apoptotic and anti-apoptotic markers (BAX, CASP3, BCL2) were measured using quantitative PCR. Estradiol and progesterone levels were quantified in culture media to evaluate functional steroidogenic output. The results revealed that DBP exposure caused a concentration-dependent increase in ROS levels, apoptosis-related gene expression, and signs of cellular senescence, particularly at concentrations \u2265\u202f25\u202f\u00b5M. Interestingly, estradiol production increased significantly with increasing DBP concentration, despite the presence of cellular stress. Gene expression analysis showed a marked upregulation of ESR1, FSHR, and CYP19A1, while ESR2 and the other key steroidogenic genes remained unchanged. These findings suggested that DBP might altered estrogenic activity through selective modulation of estrogen and FSH receptor signaling rather than through global transcriptional activation of steroidogenic enzymes. Moreover, alterations in mitochondrial membrane potential and nuclear morphology suggested the subcellular stress responses to DBP. In conclusion, DBP exerted dual effects on ovine granulosa cells by inducing oxidative stress and cellular dysfunction while simultaneously enhancing estradiol synthesis through selective receptor pathways. FSH stimulated steroidogenesis in GCs culture in the presence of DBP, yet it was unable to mitigate DBP-induced cell toxicity.\n\nID: 42096291\nTitle: Activation of the impaired NAMPT/SIRT7/SOD2 axis restores alveolar progenitor cell renewal in idiopathic pulmonary fibrosis.\nAbstract: Alveolar type 2 (AT2) progenitor cell exhaustion and impaired regenerative capacity are key pathogenic hallmarks in idiopathic pulmonary fibrosis (IPF). Nicotinamide adenine dinucleotide (NAD+) functions as a central regulator of cellular energy metabolism. We have previously reported that downregulation of NAD+-dependent sirtuin signaling contributes to the impaired progenitor cell function of IPF AT2 cells. In this study, we found that a key NAD+ biosynthesis enzyme, nicotinamide phosphoribosyltransferase (NAMPT), was significantly downregulated in IPF AT2 cells. NAMPT deficiency impaired AT2 renewal and enhanced lung fibrosis through downregulation of SIRT7 and SOD2, which resulted in increased oxidative stress, mitochondrial dysfunction, accumulated aberrant transitional cells, and impaired differentiation from AT2 to alveolar type 1 (AT1) cells. A mouse model with AT2-specific deletion of Nampt showed severely impaired AT2 renewal capacity and increased susceptibility to bleomycin lung injury. Activation of NAMPT by small-molecule activators promoted IPF AT2 renewal and reversed lung fibrosis in WT mice. NAMPT activation is a potentially promising therapeutic strategy for restoring AT2 progenitor cell function and halting or reversing progressive pulmonary fibrosis.\n\nID: 42095090\nTitle: Neuromuscular junction innervation and motor function are preserved by restoring muscarinic signaling in perisynaptic glia in ALS.\nAbstract: Neuromuscular junction (NMJ) denervation is an early pathological event in amyotrophic lateral sclerosis (ALS) causing motor dysfunction and paralysis. Glial cells at the NMJ, perisynaptic Schwann cells (PSCs), ensure a balance between maintenance and repair via muscarinic receptor signaling. However, in ALS mouse models, PSCs show an aberrant muscarinic hyperactivation. We posited that this excessive activation impairs the PSC capacity to support NMJ repair in ALS. Beginning at symptoms onset, SOD1 G37R mice received daily oral administration of darifenacin, a clinically approved type 3 muscarinic receptor antagonist, to reduce PSC hyperactivation. The treatment improved locomotion and preserved NMJ innervation in male mice, with comparable effects observed in females, and extended survival in males. Functional benefits were supported by signs of glial repair and enhanced survival of lumbar motor neurons. These preclinical data indicate that pathological PSC hyperactivity contributes to NMJ denervation in ALS and support therapeutic strategies targeting NMJs in ALS.\n\nID: 42088408\nTitle: Acute anti-proliferative and anti-migratory effects of cannabidiol on C6 rat glioma, SH-SY5Y human neuroblastoma, and HT22 mouse hippocampal neuronal cell cultures.\nAbstract: The treatment of central nervous system tumors remains challenging owing to their highly proliferative nature, aggressiveness, and poor prognosis. Additionally, existing treatment methods have several problems, including high risk of complications, systemic side effects, and impact on patients' quality of life. Recently, cannabidiol (CBD), a non-psychoactive cannabinoid found in Cannabis sativa, has emerged as an alternative therapeutic medication because of its potential antitumor activity with fewer side effects. We evaluated the cell viability, clonogenicity, migration, apoptotic nuclear morphology, and cell cycle phases of C6 rat glioma, SH-SY5Y human neuroblastoma, and HT22 immortalized mouse hippocampus neuronal cultures treated with CBD ranged between 0 and 10\u00a0\u03bcg/mL. CBD concentrations exceeding 5\u00a0\u03bcg/mL induced significant reductions in cell viability in C6 glioma and SH-SY5Y neuroblastoma cultures, accompanied by decreased clonogenicity in both cultures at 10\u00a0\u03bcg/mL. A scratch assay for cell migration revealed that 5\u00a0\u03bcg/mL CBD suppressed C6 glioma cell migration. Additionally, late apoptotic nuclear morphology was observed in C6 glioma cultures treated with 10\u00a0\u03bcg/mL cannabidiol. Similarly, HT22 hippocampal neuronal cultures exhibited decreased cell viability and clonogenicity, with apparent nuclear signs of apoptosis at CBD concentrations over 5\u00a0\u03bcg/mL. Notably, CBD disrupted HT22 cell migration at concentrations of 2.5 and 5\u00a0\u03bcg/mL. Proteomic profiling of C6 glioma revealed upregulation of ribosomal proteins, molecular chaperones, and modulators of cytoskeletal dynamics upon treatment with 1\u00a0\u03bcg/mL CBD. In comparison, treatment with 2.5\u00a0\u03bcg/mL CBD led to marked downregulation of endoplasmic reticulum chaperones, mitochondrial ATP synthase, and cytoskeletal regulators. Our findings confirm the sensitivity of glioma, neuroblastoma, and hippocampal neuronal cultures to CBD, providing valuable insights for further research into its therapeutic potential against glioma, neuroblastoma, and neuronal disorders.\n\nID: 42049434\nTitle: Microarray Analysis of Human Abdominal Aortic Aneurysm With Emphasis on Cardiovascular Genes Revealed Differentially Expressed Genes.\nAbstract: We examined gene expression profiles in abdominal aortic aneurysm (AAA) lesions vs. normal aortas by cDNA microarray and real-time quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR). Phosphorus (32P)-labeled cDNA from AAA specimens (mean AAA size 6.65 cm) and normal aortas were hybridized with a 588-gene microarray primarily of the cardiovascular system. The results were validated by qRT-PCR. A total of 35 out of the 588 genes were differentially expressed, with either log2 ratio of AAAs/controls \u22651 (upregulated; 20 genes) or \u2264-1 (downregulated; 15 genes) in AAA lesions vs. normal aorta, and 25 of these were significantly different (71%). Expression of matrix metalloproteinase 9, TIMP metallopeptidase inhibitor 3, collagen type I \u03b1 1 chain (COL1A1), COL6A3, COL15A1, intercellular adhesion molecule 1 (ICAM1), ICAM2, decorin, endoglin, apolipoprotein D (APOD), APOE, phospholipid transfer protein, calcium and integrin binding 1 (CIB1), phospholipase A2 group IIA, von Willebrand factor, serpin family B member 6 (SERPINB6), urokinase-type plasminogen activator, H19, C-C motif chemokine ligand 2, and platelet-derived growth factor receptor beta was upregulated in AAA vs. normal aorta. Expression of collagen type IV \u03b1 4 chain (COL4A4), COL11A2, gap junction protein \u03b1 1 (GJA1), biglycan, integrin subunit \u03b1 8, galectin-1, low-density lipoprotein receptor-related protein 1, acetyl-CoA acyltransferase, serpin family E member 1, melanoma cellular adhesion molecule, sodium channel epithelial 1 subunit beta (SCNN1B), natriuretic peptide receptor 1 (NPR1), superoxide dismutase 3, actinin \u03b1 1 (ACTN1) and cardiac phospholamban (PLN) was downregulated. Eleven genes differentially expressed (p\u22640.05) in AAA lesions vs. normal aortas were not reported previously: upregulated: COL6A3, COL15A1, ICAM2, APOD, CIB and SERPINB6; downregulated: GJA1, SCNN1B, NPR1, ACTN1 and PLN. Remaining results confirmed previous reports regarding 21 genes differentially expressed in AAA. qRT-PCR results were in general in agreement with microarray results.\n\nID: 42045773\nTitle: Caffeic Acid Phenethyl Ester Enhanced the Klotho/SIRT1/Nrf2/HO-1 Axis to Protect Against Methylmercury-Induced ALS-Like Neurodegeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by motor neuron degeneration, oxidative stress, and neuroinflammation. This study evaluated the neuroprotective potential of caffeic acid phenethyl ester (CAPE) against MTME\u2009+\u20095-induced neurotoxicity in an ALS-like pathology model. CAPE (50 and 100\u00a0mg/kg., p.o.) demonstrated significant therapeutic efficacy by improving motor and cognitive deficits, restoring oxidative balance, and mitigating neuroinflammatory and apoptotic pathways. Behavioral assessments, including the open field, grip strength, forced swim, and Morris water maze, highlighted CAPE's ability to restore neuromuscular coordination and cognitive function in a dose-dependent manner. Cellular and Molecular analyses revealed that MTME+5 exposure significantly disrupted Klotho/SIRT-1/Nrf2/HO-1 antioxidant signaling, increased pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and elevated apoptotic markers (Bax, caspase-3) while depleting anti-inflammatory cytokines (IL-10) and neuroprotective proteins. Furthermore, CAPE treatment restored these parameters, reduced oxidative stress, and enhanced antioxidant defenses (SOD, CAT, r-GSH). Furthermore, CAPE normalized neurotransmitter imbalances, including acetylcholine, dopamine, GABA, serotonin, and glutamate, alleviating excitotoxicity. Histopathological and gross morphological analyses confirmed CAPE50 and CAPE100 ability to preserve neuronal and myelin integrity across key brain regions, including the cerebral cortex, hippocampus, striatum, midbrain, and cerebellum. CAPE also reduced methylmercury accumulation in the brain and cerebrospinal fluid, indicating detoxifying effects. Co-administration of vitamin B1 (VTB1(200)) further amplified CAPE's therapeutic efficacy. Complete blood count (CBC) analysis demonstrated MTME+5-induced hematological abnormalities, including reduced RBCs, hemoglobin, WBCs, and platelets, alongside elevated eosinophils and basophils. CAPE treatment normalized these parameters, indicating systemic recovery. These findings establish CAPE as a promising neuroprotective agent for ALS, capable of targeting neurocomplications.\n\nID: 42039583\nTitle: A standardized framework resolves ambiguity in motor neuron loss across neurodegenerative diseases.\nAbstract: Motor neuron (MN) loss is a hallmark of neurodegenerative disorders, yet its assessment remains variable, confounding mechanistic and therapeutic interpretation. To address this, we conducted a systematic review and meta-analysis of spinal muscular atrophy (SMA) mouse studies, revealing 60% variability in reported MN loss, largely attributable to nonspecific spinal cord sampling. Using a whole-segment approach with tissue clearing, MN tracing, and multimodal imaging, we confirmed segment-dependent differences in MN counts. Common MN markers (SMI-32, Nissl) lacked specificity, whereas choline acetyltransferase (ChAT) provided robust labeling in murine and human spinal cords. Deep learning-based whole-mount segmentation enabled unbiased MN quantification and validated manual counts. Integrating analysis with computational modeling established segment sampling as a key driver of variability and revealed degeneration patterns: widespread MN loss in amyotrophic lateral sclerosis (ALS), selective MN loss in severe SMA, and preservation in mild SMA models. These findings establish a framework for reproducible MN quantification.\n\nID: 42011356\nTitle: Protective effect of pomegranate seed oil against lead acetate-induced toxicity on the hippocampus and bone marrow in rats.\nAbstract: Lead poisoning is one of the oldest occupational and environmental diseases in the world. It can enter the body by being absorbed in water, air, and food. Oxidative stress is one of the mechanisms responsible for lead toxicity. Anti-inflammatory and antioxidant properties are the primary effects of pomegranate seed oil (PSO). This research is designed to determine the impact of PSO on damage to the hippocampus, bone, and bone marrow in rats triggered by lead acetate. Thirty-two adult male rats were subjected to this study. The animals were divided into four groups at random after they had acclimated. The control group received 1 ml/kg of normal saline for 21 days. Animals in the Pb group received 500 ppm of lead acetate in drinking water for 21 days. Pb+ PSO 0.4 ml/kg and Pb+ PSO 0.8 ml/kg received 0.4 or 0.8 ml/kg of PSO intraperitoneally, concomitant with exposure to lead acetate for 21 days. Blood, bone, bone marrow, and hippocampus samples were taken after the treatment for measuring malondialdehyde (MDA), thiol content and superoxide dismutase (SOD). Our results revealed that 0.8 ml/kg of PSO significantly decreased malondialdehyde in bone marrow, serum, and hippocampus. It also could increase thiol in serum and superoxide dismutase in bone marrow. PSO could protect against lead-induced damage in bone, bone marrow, and hippocampus of treated animals through reduction of oxidative stress.\n\nID: 42004538\nTitle: Structural and morphological modulation of the myocardium by Dioscorea bulbifera saponins in experimentally induced cardiotoxicity.\nAbstract: This study investigated the ameliorative potential of a saponin derived from Dioscorea bulbifera bulbils in mitigating experimentally induced cardiotoxicity in adult male Wistar rats. Forty-eight rats were divided into eight groups (n\u202f=\u202f6). Group A received distilled water, and Group B received doxorubicin (10\u202fmg/kg). Groups C and D received SRF (50 or 100\u202fmg/kg) for 14 days. Groups E and F received doxorubicin with SRF, while Groups G and H were pretreated with SRF before doxorubicin on day 15. Blood and heart tissues were collected for analysis after euthanasia. Rats in the doxorubicin-only group (Group B) exhibited significant elevations in serum cardiac injury markers, including lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB), along with increased systolic and diastolic blood pressures and elevated malondialdehyde (MDA) levels. Conversely, activities of key antioxidant enzymes-superoxide dismutase (SOD) and catalase (CAT)-were markedly reduced. Enhanced glycogen accumulation, Caspase-3 activation, and CD4 expression further indicated heightened oxidative stress and apoptosis. Treatment with SRF, particularly in the pre- and co-administration protocols, significantly attenuated these alterations. The saponin-rich fraction of Dioscorea bulbifera bulbils demonstrated substantial cardioprotective potential against doxorubicin-induced cardiac injury, likely through its antioxidant and anti-apoptotic mechanisms.\n\nID: 42003614\nTitle: Vacuolar iron export alters the synergy between doxycycline and fluconazole by affecting cidal ROS levels in Candida albicans.\nAbstract: Fungal infections are combatted using three main classes of antifungals, of which the azoles, considered to be fungistatic, are the most widely used. Slow growth of Candida albicans at supra-minimal inhibitory concentrations (MIC) of fluconazole (FLC), termed tolerance, is routinely observed. A combination therapy resulting in the eradication of this fungistatic character would be a valid therapeutic strategy, and indeed, the synergistic combination of the antibiotic doxycycline and FLC has such an effect. We hypothesized that iron-requiring mitochondrial functions may be the targets of the synergistic combination. The proteome enriched for mitochondria obtained from FLC + Fe-treated cells hinted that iron alleviated the FLC stress and that intracellular iron homeostasis, more specifically the vacuolar iron exporter Smf3, might be a key factor during FLC treatment, as its expression was induced. Moreover, a ROS assay revealed that a smf3\u0394/\u0394 strain treated with FLC accumulated ROS to a similar extent as that displayed by the WT undergoing a FLC+DOX combination treatment. Thus, deletion of SMF3 mimics the addition of doxycycline in wild-type cells. The ROS accumulation can be attenuated through overexpression of the mitochondrial superoxide dismutase SOD2, and this restored the synergy between DOX and FLC in the smf3\u0394/\u0394 background. ROS accumulation, in part through altered iron availability from the vacuolar storage pool, is thus the molecular mechanism underlying the synergy between doxycycline and FLC. Furthermore, no effect on either cidality or tolerance was observed in the smf3\u0394/\u0394 strain, highlighting that synergy is not necessarily an indication of cidal therapies.IMPORTANCEAzoles are widely used against Candida albicans, yet many cells survive above the minimal inhibitory concentrations (MIC) by growing slowly, which can prolong infection and foster resistance. We show that intracellular iron homeostasis alters the fluconazole characteristics by affecting ROS accumulation in mitochondria, and that this is the molecular mechanism underlying the combination therapy of fluconazole and doxycycline. These results place iron release from the vacuole at the center of azole responses, suggesting novel ways to boost azole efficacy.\n\nID: 42001273\nTitle: Protective Effects of Daucus carota and Piper nigrum Extracts against Methotrexate-Induced Testicular Damage in Rats.\nAbstract: This research aimed to investigate the effects of alcoholic extracts from Daucus carota and Piper nigrum on testicular damage induced by methotrexate (MTX) in rats. In this experimental study, a total of 49 rats were randomly divided into seven groups, receiving MTX (20 mg/kg) alone and in conjunction with different doses of Daucus carota extract (200 and 400 mg/kg), Piper nigrum extract (15 and 7.5 mg/kg), a combination of Pipe nigrum at 7.5 mg/kg, and Daucus carota at 200 mg/kg, and a control group. The extracts were given orally through gavage starting one day before MTX treatment and continuing for two weeks. The study measured blood testosterone levels, Johnson's index, and seminiferous tubule diameter from tissue sections. It also assessed markers of oxidative stress [reactive oxygen species (ROS), Nitrite, malondialdehyde (MDA), glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), as well as levels of myeloperoxidase (MPO), mitochondrial membrane potential (MMP), and the consistency of testicular tissue. The MTX-exposed group exhibited remarkable testicular tissue damage, as indicated by increased ROS, MDA, and Nitrite levels compared to the control group. Moreover, there were notable reductions in CAT, GSH, SOD, testosterone levels, Johnson index, and seminiferous tubule diameter in the MTX-treated rats. However, treatment with Pipe nigrum and the combination of Pipe nigrum with Daucus carota extracts significantly reduced testicular damage and reduced oxidative stress markers compared to the MTX group. The study suggests that alcoholic extracts of Daucus carota and Pipe nigrum may help alleviate the harmful effects of MTX on testicular tissue, potentially offering a therapeutic option for male infertility due to chemotherapyrelated testicular damage.\n\nID: 42000032\nTitle: Effects of Chinese herbal mixture extract on growth, immunity, antioxidant status, and modulates rumen microbiota in weaned lambs.\nAbstract: The weaning process in lambs induces physiological stress that heightens susceptibility to pathogens and environmental challenges. This study investigated the effects of a Chinese Herbal Mixture Extract (CHE) comprising honeysuckle, astragalus, M. officinalis and tangerine peel as a dietary supplement in weaned lambs. Forty-eight 60-day-old lambs were randomly assigned to four groups: control (CON, basal diet), and basal diet supplemented with 0.1% (LCHE), 0.2% (MCHE), or 0.4% CHE (HCHE) for 56 days. Growth performance, immunity, antioxidant status, biochemical parameters, organ histology and rumen microbiota were evaluated. Data were analyzed by one-way ANOVA. Compared with CON, MCHE and HCHE significantly increased average daily gain (ADG) and decreased the feed-to-gain ratio (F/G) (P\u202f<\u202f0.05). In addition, apparent digestibility of crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) was improved (P\u202f<\u202f0.05). These groups showed growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels (P\u202f<\u202f0.05), increased immunoglobulin (IgA, IgG) concentrations and superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) activities (P\u202f<\u202f0.05), and reduced malondialdehyde (MDA) (P\u202f<\u202f0.05). The HCHE increased serum total protein (TP) and calcium (Ca) at day 56 (P\u202f<\u202f0.05). Dietary CHE supplementation (0.1% - 0.4%) increased the villus height-to-crypt depth ratio (P\u202f<\u202f0.05), with no significant pathological lesions observed in major organs upon histological examination. Microbiota analysis showed that CHE reshaped rumen microbiota, increased the relative abundance of Euryarchaeota (P\u202f<\u202f0.05), which have a positive effect on enhancing carbohydrate and lipid metabolic pathways based on inferred functional potential. Dietary CHE supplementation alleviated weaning stress and enhanced growth performance in lambs by improving immune function, antioxidant capacity and rumen microbiota composition.\n\nID: 41983194\nTitle: Dynamic changes in excitability and viability of sporadic and SOD1-related amyotrophic lateral sclerosis iPSC-derived motor neurons.\nAbstract: To explore the dynamic changes in excitability and viability of induced pluripotent stem cells (iPSC)-derived motor neurons from sporadic amyotrophic lateral sclerosis (ALS) and compare them with SOD1-related ALS patients and healthy control. Peripheral blood samples were collected from ALS patients and healthy controls (HC) to establish the iPSC-derived motor neurons (MNs). Whole-cell patch-clamp recordings at different culture stages was made using an Axopatch 700B amplifier in combination with pClamp 11 software (Molecular Devices). The frequency of action potentials (APs) was recorded. Additionally, Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) Nick-End Labeling (TUNEL) was used to assess the apoptosis of MNs. ALS patient-derived MNs exhibited significantly higher firing rates compared to HCs at both 4-7 weeks (p = 0.004) and 7-9 weeks (p = 0.009). Further analysis revealed that SOD1-derived MNs showed significantly higher firing frequencies than sALS (p = 0.009) and HCs (p < 0.001) in 4-7 weeks. In 7-9 weeks, it remained significant between SOD1 and HC-derived MNs (p = 0.015), but became insignificant between SOD1 and sALS (p = 0.855). The apoptotic rate of sALS (Day 30: 61.37% \u00b1 9.63%; Day 60: 78.41% \u00b1 6.63%) and SOD1 (Day 30: 73.69% \u00b1 8.81%; Day 60: 60.37% \u00b1 11.53%) -derived MNs was significantly higher than those of HCs at both Day 30 (30.72% \u00b1 7.57%) and Day 60 (50.85% \u00b1 19.36%) (p < 0.001). MNs derived from both patients with mutant SOD1 and sporadic ALS exhibited increased excitability compared to HCs. The increased excitability of MNs derived from ALS patients with mutant SOD1 occurred earlier, and over time, became consistent with the excitability observed in MNs derived from sporadic ALS. The apoptosis rates of MNs showed similar trends. iPSC-derived MNs from both sporadic and mutant ALS may serve as useful cell models for ALS in future studies.\n\nID: 41968605\nTitle: An Integrated Nanozyme-Exosome Platform for Multi-Targeted Therapy of Metabolic-Associated Steatotic Liver Disease.\nAbstract: Metabolic-associated steatotic liver disease (MASLD) is a prevalent chronic liver disorder driven by a complex interplay of lipid accumulation, oxidative stress, and inflammation, for which effective targeted therapies remain limited. To address this multifactorial pathology, we developed an integrated nano-therapeutic platform, termed CMEPA, that unites three complementary components: a copper-based nanozyme with dual superoxide dismutase (SOD)- and catalase (CAT)-like activities, human umbilical cord mesenchymal stem cell-derived exosomes (UC-MSC-Exos) enriched in regulatory microRNAs, and a hepatocyte-targeting antibody against ASGR1. In vitro, CMEPA efficiently scavenged reactive oxygen species (ROS), significantly reduced lipid droplet accumulation, and suppressed apoptosis in palmitic acid-challenged hepatocytes. In vivo, CMEPA exhibited preferential hepatic accumulation and an excellent biosafety profile, with no observable systemic toxicity. Therapeutic evaluation in a diet-induced murine MASLD model revealed that CMEPA administration significantly improved serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride, and cholesterol levels, alleviated hepatic steatosis as confirmed by histopathology, enhanced endogenous SOD and CAT activities, and attenuated inflammatory and lipogenic signaling pathways, as revealed by transcriptomic analysis. Collectively, these results establish CMEPA as a robust, multi-modal nano-therapeutic strategy that integrates catalytic antioxidation, exosome-mediated gene regulation, and active hepatocyte targeting, offering a promising translational approach for MASLD treatment.\n\nID: 41960705\nTitle: Protective effect of nebivolol on bleomycin-induced lung fibrosis via suppressing TLR4/IL-1\u03b2/MMP-2 and TGF-\u03b2/HSP47 signaling pathways in rats.\nAbstract: Idiopathic pulmonary fibrosis (IPF), a potentially fatal illness, significantly alters normal lung structure and function, resulting in severe respiratory failure and death. As of yet, no curable remedy has been revealed. Nebivolol is a third-generation \u03b2-blocker that has numerous cytoprotective properties and is used to treat heart failure and hypertension. Its potential ability to prevent bleomycin-induced IPF has not been studied. The aim of the current study is to investigate the antifibrotic effect of nebivolol against bleomycin-induced lung fibrosis. Twenty-four male Wistar rats were randomly divided into four groups (n\u2009=\u20096 per group): control, bleomycin, nebivolol, and nebivolol\u2009+\u2009bleomycin. Pulmonary fibrosis was induced by bleomycin administration, while nebivolol was given seven days prior to a single intratracheal injection of bleomycin, daily orally for 21\u2009days. At the end of the study, lung injury and fibrosis were evaluated using histopathological analysis, lung wet/dry ratio, bronchoalveolar lavage fluid protein content, oxidative stress markers, inflammatory cytokines, and fibrosis-related signaling. Nebivolol significantly decreased the histopathological injuries demonstrated through lung tissue sections stained by hematoxylin/eosin and silver. It considerably decreased the lung wet/dry ratio, as well as the total protein level in bronchoalveolar lavage fluid. Further, nebivolol restored superoxide dismutase activity and suppressed elevated malondialdehyde levels, rebalancing the disrupted oxidative indicators. Nebivolol is additionally known to have anti-inflammatory effects, as demonstrated by a decrease in cytokine levels, including tumor necrosis factor-alpha (TNF-\u03b1), interleukin-1 beta (IL-1\u03b2), and interleukin-6 (IL-6), while boosting the secretion of the anti-inflammatory mediator endothelial nitric oxide synthase. In addition, nebivolol's anti-inflammatory properties were obvious by its suppressing effect on Toll-like receptor 4 (TLR4) level and the matrix metalloproteinase-2 (MMP-2) expression. Finally, nebivolol mitigated the progression of the fibrotic cascade, as indicated by reducing the elevated levels of transforming growth factor beta (TGF-\u03b2) and heat shock protein 47 (HSP47). Nebivolol treatment exhibited remarkable protective effects on bleomycin-mediated IPF in rats via suppressing TLR4/IL-1\u03b2/MMP-2 and TGF-\u03b2/HSP47 signaling pathways. This study might provide an innovative therapeutic approach to prevent the devastating lung scarring associated with IPF.\n\nID: 41959547\nTitle: Fabrication of methotrexate conjugated multi-walled carbon nanotubes for the evaluation of cytotoxic potential at biochemical and molecular level modulating BAX, BCL-2 and telomerase expression.\nAbstract: Cancer is one of the leading causes of mortality all across the world, and the clinical applications of numerous chemotherapeutic agents are limited by major side effects. Among these, methotrexate (MTX) is a widely used anticancer drug which exhibits certain limitations related to biocompatibility and solubility. Therefore, to address these limitations, MTX was covalently conjugated to multi-walled carbon nanotubes (MWCNTs) to develop a stable and targeted nanotherapeutic system. MWCNTs were first subjected to purification followed by carboxylation which was validated through dispersion solubility test. MTX-MWCNT was then subjected to characterization to validate successful conjugation after which the cytotoxic potential of MTX-MWCNT was assessed by cell viability assay on MCF-7 (hormone-positive breast cancer), MDA-MB 231 (triple-negative breast cancer), and HeLa (cervical cancer) cells. The evaluation of safety profile and hemocompatibility was done using non-cancerous HEK 293T (human embryonic kidney) cells and in vitro hemolysis assay respectively. The cytotoxic potential of MTX-MWCNT was assessed through cell viability assay which demonstrated a dose-dependent reduction in cancer cell viability after treatment with MTX-MWCNTs with minimal toxicity toward normal cells and blood. The anti-angiogenic potential of MTX-MWCNT was also tested further through ex vivo chick chorioallantoic membrane (CAM) assay which revealed significant reduction in vessel branching. The cytotoxic activity of MTX-MWCNT was also confirmed by biochemical assays, including cell proliferation assay, glucose estimation assay, and total antioxidant status (TAS). Moreover, the cytotoxic potential of MTX-MWCNT was further assessed at the gene level through quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis which demonstrated upregulation of the pro-apoptotic BAX gene and downregulation of the anti-apoptotic BCL-2 gene. Furthermore, kit-based enzyme-linked immunosorbent assay (ELISA) quantification further confirmed increased BAX, decreased BCL-2, and reduced telomerase protein expression. Lastly, the alteration in nuclear morphology in all three cancer cells post treatment with MTX-MWCNTs was evaluated through 4',6-diamidino-2-phenylindole (DAPI) staining followed by fluorescence microscopy. Collectively, the obtained findings highlight that MTX-MWCNT efficiently induces apoptosis and inhibits angiogenesis while maintaining significant biosafety, establishing it as an emerging nanoscale platform for targeted cancer therapy.\n\nID: 42389275\nTitle: Role of gut microbiota in melanosis coli: from anthraquinone biotransformation to mucosal homeostasis dysbiosis.\nAbstract: Melanosis coli (MC) is a benign and usually reversible condition characterized by brownish-black pigmentation of the colonic mucosa and is commonly associated with chronic exposure to anthraquinone laxatives (ALs). The best-established histopathological sequence involves AL-related epithelial apoptosis, phagocytosis of apoptotic bodies by macrophages, and subsequent lipofuscin deposition. Emerging evidence suggests that the gut microbiota (GM) may contribute to this process by converting pharmacologically inactive anthraquinone glycosides into active anthrone metabolites, including rhein anthrone. This narrative review summarizes available MC-specific findings and clearly distinguishes them from mechanistic hypotheses extrapolated from constipation, intestinal barrier, and microbiome literature. We discuss microbial \u03b2-glucosidases and reductases involved in AL biotransformation, reported changes in microbial diversity and SCFA-producing taxa in MC or constipation-associated cohorts, and plausible links with barrier dysfunction, bile-acid metabolism, tryptophan-derived metabolites, and LPS-TLR4 signaling. We therefore present the \"Microbiota-Apoptosis Axis\" as a proposed framework rather than a validated causal pathway. Finally, we review GM-targeted strategies, including probiotics, synbiotics, and fecal microbiota transplantation, while emphasizing that direct clinical evidence in MC remains limited and that cessation of anthraquinone laxatives remains the primary management strategy.\n\nID: 42301485\nTitle: Copper homeostasis and cuproptosis in cancer: mitochondrial metabolic dependency and nanomedicine-based therapeutic strategies.\nAbstract: Copper (Cu), as an essential trace element, is involved in a variety of key biological processes, such as mitochondrial respiratory chain, antioxidant defense, and cellular signal transduction. It is also potentially toxic while maintaining life activities: once intracellular free copper increases or becomes imbalanced, it may trigger a cascade of stress responses, including protein misfolding, disruption of redox homeostasis, and mitochondrial dysfunction. Therefore, the body maintains copper homeostasis through fine-tuned uptake, transport, storage, and efflux systems, ensuring copper remains in dynamic balance. Tumor cells often undergo adaptive changes in metal ion homeostasis in response to metabolic reprogramming and microenvironmental selective pressures. Abnormal copper metabolism has been considered closely related to tumor development, invasion, metastasis, and treatment tolerance. In recent years, cuproptosis has provided a new theoretical framework for studying the relationship between copper and tumors. Our manuscript expounds on the therapeutic value of copper and cuproptosis in tumor progression and treatment, providing a new entry point for updating accurate cancer treatment strategies.\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: 42250949\nTitle: Calcium overload induces reactive oxygen species to enhance glioblastoma radiosensitivity.\nAbstract: Radiotherapy is the primary treatment of glioblastoma, but its efficacy is often limited by tumor cell resistance to radiation. Radiotherapy mainly has its cytotoxic effect through the formation of reactive oxygen species and the damage to DNA. Nevertheless, to overcome the effects of reactive oxygen species- mediated oxidative damage and endoplasmic reticulum stress, tumor cells may activate the repair mechanisms to stress and improve antioxidant defenses. This study innovatively proposes the use of the calcium ionophore ionomycin as a radiosensitizer in glioblastoma. We used U87MG and U251 cell lines as well as subcutaneous xenograft mice as models, and conducted a combined intervention of ionomycin and radiotherapy. Mechanistically, ionomycin selectively disrupted endoplasmic reticulum calcium homeostasis, inducing severe and sustained endoplasmic reticulum stress. When combined with radiotherapy, this led to a marked surge in intracellular reactive oxygen species, and significantly enhanced apoptosis. In vitro, the combination treatment synergistically reduced cell viability, clonogenicity, and proliferation compared with either monotherapy. In vivo, ionomycin combined with radiotherapy substantially suppressed tumor growth and increased intratumoral reactive oxygen species levels and apoptosis. These findings indicate that ionomycin converts repairable adaptive stress into irreversible lethal damage by amplifying reactive oxygen species through an endoplasmic reticulum stress-reactive oxygen species vicious cycle, thereby overcoming antioxidant defenses and enhancing glioblastoma radiosensitivity. JOURNAL/mgres/04.03/01612956-990000000-00103/inline-graphic1/v/2026-06-06T092807Z/r/image-tiff.\n\nID: 42246025\nTitle: Editorial: Regulated cell death and neurological diseases.\nAbstract: \n\nID: 42243993\nTitle: Hyperoside protects against poly-GR-mediated neurodegeneration via regulation of mitochondrial fission and oxidative stress in C9orf72-associated ALS.\nAbstract: Arginine-rich poly-glycine-arginine (poly-GR), a toxic dipeptide repeat protein generated from C9orf72 hexanucleotide repeat expansion, drives mitochondrial dysfunction, oxidative stress, and neuronal loss in amyotrophic lateral sclerosis (ALS). Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS.\n\nID: 42242586\nTitle: Early-onset neuroinflammation drives neurodegeneration caused by lysosomal PI(3,5)P2 insufficiency.\nAbstract: Phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2] is a lysosomal signaling lipid whose deficiency, caused by mutations in the PIKfyve complex subunits FIG4 or VAC14, underlies a spectrum of fatal neurologic diseases including Charcot-Marie-Tooth type 4J (CMT4J) and amyotrophic lateral sclerosis (ALS). To map the molecular consequences of PI(3,5)P2 insufficiency in the brain, we performed quantitative proteomic and transcriptomic analyses of three mouse lines bearing distinct loss-of-function mutations in Fig4 or Vac14, examining the brain at the presymptomatic and end stages. Strikingly, profound neuroinflammation was already present at postnatal day 5 (before significant neurodegeneration), characterized by complement activation, interferon signaling, and parenchymal infiltration of peripheral myeloid cells and T-cells. Isolated mutant microglia exhibited a markedly pro-oxidative transcriptional state with elevated reactive oxygen species, a partly non-cell-autonomous phenotype, being present in microglia from mice with conditional Fig4 inactivation in just neurons and astrocytes. Comparison of early (P5) and late (P25) proteomics data revealed that PI(3,5)P2 insufficiency impairs developmental remodeling of the brain proteome: proteins typically upregulated during postnatal maturation failed to accumulate, implicating lysosomal function in neurodevelopment. We identify coordinated elevation of p53, Fas receptor, inflammatory caspases, Gasdermin D, RIPK1, and ZBP1, consistent with multifactorial inflammatory cell death with features of apoptosis, pyroptosis, and necroptosis. Many of the dysregulated proteins are encoded by genes mutated in lysosomal storage disorders, ALS, CMT, Alzheimer's and Parkinson diseases, extending the pathogenic relevance of PI(3,5)P2 insufficiency. Together, these findings establish that early neuroinflammation is a defining - and likely initiating - feature of neurodegeneration caused by disruption of lysosomal PI(3,5)P2.\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: 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\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: 42177227\nTitle: Nrf2/Bach1-ARE pathway are involved in the ameliorative effects of astaxanthin on D-galactose-induced liver and brain aging and injury.\nAbstract: Astaxanthin (ATX), a natural antioxidant whose benefits in age-related liver and kidney damage remain unclear. We established a D-galactose-induced ageing model in rats and observed the daily behaviour of the rats. Using staining methods to detect ROS, apoptosis and histopathological changes in liver and brain tissue. Determination of antioxidant levels of IL-2, IL-6 and AGES in rats. Assessment of cognitive function using the Morris water maze and ChAT. The mRNA and protein expression levels of Nrf2, Bach1, SOD1, SOD2, HO-1 were determined by real-time PCR and Western blotting. To investigate the role of the Nrf2/Bach1-ARE pathway, we used ML385, a specific inhibitor of the Nrf2 pathway, to treat rats in the inhibitor group. Aging rats showed impaired learning and memory, along with decreased levels of neurotransmitters and antioxidant enzymes. ATX and vitamin E (VE) interventions significantly alleviated these symptoms and activated the Nrf2/Bach1-ARE pathway in liver and brain tissues of aged SD rats. Furthermore, the protective effects of ATX were attenuated by the addition of the Nrf2 inhibitor ML385. ATX reduces oxidative stress and ameliorates liver and brain damage in aged rats via activation of the Nrf2/Bach1-ARE pathway.\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: 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: 42158360\nTitle: Apoptosis-related gene model predicts the prognosis in patients with acute myeloid leukemia.\nAbstract: Acute myeloid leukemia (AML) is a hematological malignancy with a high mortality rate and heterogeneous prognosis. Traditional risk stratification is based on the genetic classification in the 2022 guidelines of the European Leukemia Net. However, the risks of some patients remain unclear, and other prognostic assessment methods are required to improve the risk assessment of these patients. Apoptosis-related genes (ARGs) play critical roles in regulating the survival and drug resistance of AML cells. Therefore, we collected gene expression and clinical data from patients with AML from The Cancer Genome Atlas Acute Myeloid Leukemia (TCGA-LAML) datasets to develop a risk assessment model based on 5 ARGs. Using the least absolute shrinkage and selection operator Cox regression (LASSO-Cox) model, we identified 5 key ARGs (DDIT4, HSP90B1, ENO1, SOD1, and SLC7A11) and constructed a 5-ARG prognostic model. Using this model, we successfully stratified patients in both TCGA-LAML training and independent external validation cohorts, with high-risk patients consistently exhibiting significantly poorer clinical outcomes. In addition, high-risk patients exhibited significant enrichment in pathways related to TP53 dysfunction, mechanistic target of rapamycin complex 1 (mTORC1) signaling activation, and pro-inflammatory responses, which were closely correlated with NPM1c-FLT3 co-mutations. Decitabine, sunitinib, and MK-1775 were identified as potential therapeutic agents. In summary, we established a 5-ARG prognostic model that may facilitate risk stratification and inform therapeutic decision-making in AML.\n\nID: 42136278\nTitle: Therapeutic Insights into Natural Products for Modulating Neurodegenerative Disease Pathways.\nAbstract: Neurodegenerative Disorders (NDs), such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and Amyotrophic Lateral Sclerosis (ALS), are chronic and progressive conditions marked by the gradual loss of neuronal structure and function. These disorders lead to cognitive, motor, and sensory decline, significantly reducing quality of life and posing a major global health burden due to rising healthcare costs and the absence of curative therapies. This review aims to comprehensively explore the therapeutic potential of natural products in targeting cellular and molecular mechanisms underlying NDs, highlighting their neuroprotective roles and potential for disease modification. A comprehensive literature review was conducted using databases including PubMed, Scopus, Web of Science, and Google Scholar. Peer-reviewed articles, clinical trials, and experimental studies were analyzed to evaluate the therapeutic potential of natural products and their bioactive compounds in the management of NDs. ND pathogenesis involves oxidative stress, neuroinflammation, mitochondrial dysfunction, and abnormal protein aggregation, ultimately leading to neuronal death. Current therapies largely provide symptomatic relief without altering disease progression. Natural products from plants, fungi, and marine sources demonstrate strong neuroprotective potential through multitargeted mechanisms. Bioactive compounds such as flavonoids, alkaloids, terpenoids, and polyphenols exhibit antioxidant, anti-inflammatory, anti-apoptotic, and neuroprotective activities. Key molecules, including curcumin, resveratrol, luteolin, quercetin, and catechins, modulate signaling pathways such as NF-\u03baB, MAPK, PI3K/AKT, Nrf2, apoptosis, and autophagy, thereby reducing amyloid-beta aggregation, protecting dopaminergic neurons, improving mitochondrial function, and enhancing cognition in preclinical and clinical studies. Natural products represent promising candidates for disease modification in NDs due to their multi-pathway actions and relatively low toxicity. However, major limitations, such as poor bioavailability, pharmacokinetic variability, and the lack of standardized formulations, hinder clinical translation. Innovative strategies, including advanced drug-delivery systems, structural modifications, and synergistic formulations, are needed to overcome these barriers. Natural products hold significant therapeutic potential in managing neurodegenerative diseases by targeting multiple pathological mechanisms. Their integration into ND treatment could provide safer and more effective alternatives, but further well-designed clinical trials are essential to establish their efficacy and facilitate clinical application.\n\nID: 42114427\nTitle: Ecotoxicological implications of environmental neurotoxin \u03b2-N-methylamino-L-alanine (BMAA) in fishes: An emerging concern.\nAbstract: Harmful algal blooms (HABs), intensified by climate change, eutrophication, and altered hydrological regimes, are expanding globally, releasing cyanotoxins that threaten aquatic ecosystems and human health. \u03b2-N-methylamino-L-alanine (BMAA), a non-protein amino acid with neurotoxic potential, has been recognized as a global emerging concern. Following exposure, BMAA is present in both free and protein-bound forms, forming an endogenous toxin reservoir that exacerbates potential neurotoxicity in aquatic organisms and humans. Its presence in aquatic food webs not only elevates ecological risks for wildlife but also raises potential human health concerns, particularly its potential association with neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), Alzheimer's disease, and the ALS/Parkinsonism-dementia complex. This review aims to explore current knowledge of the ecotoxicological impacts of BMAA in fishes, focusing on developmental, behavioural and cognitive perturbations, along with their mechanistic underpinnings. BMAA exposure induces developmental abnormalities, including convulsions, spinal axis malformations, pericardial edema, and altered heart rate, as well as neurodevelopmental impairments, such as reduced motor neuron length and altered neuromuscular colocalization in fishes. Additionally, BMAA exposure affects a wide array of behaviours in fishes, including motor coordination, locomotion, feeding, startle responses, anxiety-like behaviours, and cognitive performance, primarily through excitotoxicity, oxidative stress, apoptosis, metabolic disruption, neuroendocrine modulation, and dysregulated neurotransmitter signalling. Future research should focus on more environmentally relevant exposure scenarios, elucidating BMAA toxicokinetics, and investigating cyanotoxin co-exposure toxicity in fishes. Advancing integrative phenotypic endpoints and knowledge of molecular mechanisms of BMAA toxicity in aquatic organisms is essential for effective ecological risk assessments and for developing regulatory standards to safeguard aquatic ecosystems and human health.\n\nID: 42096016\nTitle: Impact of melatonin injection in improving ovarian function in aged female pigeon.\nAbstract: Melatonin (MT) has been shown to extend laying period in aged hens, but its effects on aging pigeons remain unclear. 36 pairs of 5-year-old White King pigeons were assigned to either a treatment group receiving 1\u00a0mg of MT for five days or a control group given saline. The effect of MT injection on egg production in pigeon, assess histological characteristics of follicles, antioxidant parameters level and the related gene mRNA levels, steroid hormone levels and the expressions of synthesis genes on the fifth day of the laying interval. MT treatment significantly improved various aspects of egg quality. Moreover, MT increased follicle diameter and granulosa cell layer (GCL) thickness (P\u2009<\u20090.05). MT levels were elevated in plasma and hierarchy follicles yolks (P\u2009<\u20090.05). Progesterone concentrations rose in plasma (P\u2009<\u20090.05), however, estradiol levels decreased in plasma, F1 and F2 yolks (P\u2009<\u20090.05). MT also reduced ROS and MDA levels in plasma and F1 yolk (P\u2009<\u20090.05). Meanwhile, activities of SOD, TAC, and GSH-PX were significantly increased (P\u2009<\u20090.05). MT upregulated SOD1, CAT, and BCL2 mRNA levels in ovary and F1 GCL (P\u2009<\u20090.05). MT significantly increased ovarian expressions of HSD3B1 and CYP11A1, reducing HSD17B1 mRNA levels (P\u2009<\u20090.05); In F1 and F2 GCL, CYP11A1, CYP17A1, and CYP19A1 expressions were all elevated (P\u2009<\u20090.05). These findings suggest that MT promotes hierarchy follicle maturation, reduces apoptosis, thus extending egg-laying period in aging pigeons.\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: 42086533\nTitle: Proteasomal-dependent CHK1 degradation leads to DNA damage accumulation in ALS cellular model systems.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterised by the aggregation of TDP-43 and mutant FUS in the cytoplasm of affected motor neurons. Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates.\n\nID: 42085907\nTitle: Bmal1 regulates hippocampal oxidative damage in cognitive memory impairment induced by artificial light at night in mice.\nAbstract: Artificial light at night (ALAN) has emerged as a significant public health concern, yet its effects on cognitive impairment remain poorly understood. This study investigated the impact of 28 consecutive days of 5-lx ALAN exposure on hippocampal function in C57BL/6\u00a0J mice. We evaluated locomotor behavior, neuronal morphology, neurogenesis, oxidative stress, and circadian rhythms, revealing that ALAN induces cognitive impairment. ALAN exposure reduced Bmal1 expression, increased reactive oxygen species (ROS) and malondialdehyde accumulation, and disrupted the time-of-day-dependent differences expression of NRF2, SOD1, and GPX1. These alterations suppressed SOD and GPX enzymatic activity, leading to hippocampal oxidative damage. To clarify BMAL1's role, we used adeno-associated virus (AAV) to modulate Bmal1 expression in the hippocampus. ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression. These findings suggest that ALAN can contribute to memory impairment by disrupting hippocampal damage and impairing neurogenesis through its effect on Bmal1. This study identifies potential molecular targets for preventing and treating cognitive impairment and neurodegenerative disorders.\n\nID: 42076688\nTitle: Protective Effects Assessment of Combined Extracts from Periplaneta americana Residues and Cybister chinensis Motschulsky on Feline Renal Cells: In Vitro Evidence Related to Inflammation, Oxidative Stress, and Fibrosis.\nAbstract: With the rising prevalence of feline kidney diseases, effective preventive and therapeutic strategies are urgently needed. This study evaluated the effects of Cybister chinensis extracts (CCME) and Periplaneta americana residue extracts (PAE) on inflammation-associated, oxidative stress-related, and fibrosis-related responses in Crandell-Rees Feline Kidney (CRFK) cells. Using MTT assays, flow cytometry, and qPCR, we assessed cytoprotection in models of lipopolysaccharide (LPS)-, hydrogen peroxide (H2O2)-, and palmitic acid (PA)-induced injury. Preliminary HPLC fingerprint analysis of three batches of a combined extract from Periplaneta americana residues and Cybister chinensis Motschulsky (CPCE) revealed similar chromatographic profiles, indicating good batch-to-batch consistency. Within non-cytotoxic ranges, CPCE increased cell viability and reduced apoptosis in injured CRFK cells. Anti-inflammatory effects were evidenced by significant downregulation of TNF-\u03b1 and IL-6 mRNA. Potential antioxidant-related effects were suggested by decreased expression of oxidative stress-responsive genes SOD1, CAT, and GSTP1. In the PA model, anti-fibrotic potential was supported by reduced TGFB1 expression, accompanied by improvements in inflammatory and oxidative stress markers, and by decreased levels of fibrosis-associated markers \u03b1-SMA, COL I, and HCB III. These findings suggest that CPCE exerts cytoprotective effects in vitro, potentially through modulation of inflammation, oxidative stress, and fibrosis.\n\nID: 42074133\nTitle: Pridopidine Protects ALS Patient-Derived Neural Progenitor Cells via Sigma-1 Receptor Activation.\nAbstract: The sigma-1 receptor (S1R) is an endoplasmic reticulum (ER)-resident protein enriched at the mitochondria-associated ER membranes (MAMs) that supports ER homeostasis, preserves mitochondrial function, and enhances cell survival under stress. Disruptions of MAM integrity and prolonged ER stress are well-recognized pathological features of amyotrophic lateral sclerosis (ALS), contributing to motor neuron dysfunction and degeneration. In this study, we evaluated the protective effects of pridopidine, a highly selective and potent S1R agonist currently in clinical development for Huntington's disease (HD) and ALS, using neural progenitor cells (NPCs) derived from induced pluripotent stem cells (iPSCs) from a patient with sporadic ALS. Exposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted mitochondrial membrane potential, upregulated expression of the mitochondrial apoptotic marker, BAX, increased caspase-3 activation, and reduced cell viability. Pridopidine significantly attenuated tunicamycin-induced BiP and CHOP expression in a biphasic, dose-dependent manner (with maximal efficacy at 1 \u00b5M), consistent with the typical pharmacology of S1R agonists. Pridopidine restored mitochondrial membrane potential, reduced mitochondrial apoptotic signaling, shown by decreased BAX expression and caspase-3 activation, and improved survival of ALS-NPCs under ER stress. Co-treatment with the selective S1R antagonist, NE-100, attenuated these effects, supporting an S1R-mediated mechanism of action for pridopidine. Together, these results demonstrate that S1R activation by pridopidine mitigates ER-stress-induced mitochondrial dysfunction and cell loss in ALS-NPCs, resulting in enhanced survival of NPCs supporting the therapeutic potential of pridopidine in ALS.\n\nID: 42070160\nTitle: miRNAs in Amyotrophic Lateral Sclerosis: Tiny Molecules, Tremendous Impact.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder distinguished by progressive motor neuron degeneration, with diverse clinical manifestations and complex genetic and environmental triggers. The variability in disease progression underscores the necessity for tailored diagnostic and therapeutic approaches. MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression, have emerged as promising biomarkers and therapeutic targets in ALS. Dysregulation of specific miRNAs has been linked to mechanisms of ALS, including neuromuscular dysfunction, neuroinflammation, and neuronal survival/apoptosis. The potential of miRNA-based therapies, such as mimics and inhibitors, offers a more integrated approach by modulating entire disease networks, rather than targeting isolated pathways. However, challenges persist, particularly in delivering these therapies efficiently across the blood-brain barrier and minimizing off-target effects. Current delivery strategies involving nanoparticles, viral vectors, and exosome-based approaches require optimization for clinical use. This review synthesizes the latest research on miRNA-mediated mechanisms in ALS, evaluating their diagnostic, prognostic, and therapeutic potential, while highlighting the current limitations in clinical validation. It underscores the importance of standardized methodologies, multi-omics integration, and rigorous validation to facilitate the clinical translation of miRNA-based strategies. Standardized protocols and multicenter validation in large cohorts are essential to confirm the diagnostic accuracy of miRNAs, paving the way for their clinical application in ALS precision medicine.\n\nID: 42062868\nTitle: IRE1-XBP1driven induction of TMED9 stabilizes ATF6 during ER stress to promote cell survival.\nAbstract: The endoplasmic reticulum (ER) plays a central role in protein homeostasis by facilitating the folding, modification, and quality control of secretory and membrane proteins. Disruption of ER function results in protein misfolding and ER stress, which activate the unfolded protein response (UPR). While the three canonical UPR branches, inositol-requiring enzyme 1 (IRE1), protein kinase RNA-like endoplasmic reticulum kinase (PERK), and activating transcription factor 6 (ATF6), have been extensively studied, the mechanisms that coordinate their activities and ultimately dictate survival or death remain poorly understood. Transmembrane P24 trafficking protein 9 (TMED9), a cargo receptor that cycles between the ER and Golgi, has been implicated in protein quality control under pathological conditions, but its physiological role in ER proteostasis and UPR signaling is unclear. The ER stress response was studied in cellular human models including normal epithelial cells and patient-derived pediatric glioma cultures. To define the regulatory mechanisms dictating TMED9 expression, quantitative Reverse Transcription polymerase chain reaction (qRT-PCR), luciferase reporter assay, and western blotting were employed. To elucidate TMED9 function, loss-of-function approaches, including clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9-mediated knockout and small interfering RNA knockdown were used in combination with RNA-seq and live imaging. Protein stability was tested by pulse-chase experiments, ubiquitination, and degradation analyses. To study the implications of TMED9 activation, we screened curated gene expression datasets from the European Molecular Biology Laboratory- European Bioinformatics Institute (EMBL-EBI) Expression Atlas and employed live-cell imaging-based assays and functional assays (cell viability, apoptosis, migration, and self-renewal). Our study uncovers a physiological role for TMED9 in ER proteostasis and UPR signaling. We show that, under ER stress, TMED9 expression is transcriptionally induced by the IRE1-spliced X-box binding protein 1 (XBP1s) pathway via a conserved unfolded protein response element (UPRE)-like element in its promoter. Removal of TMED9 selectively impairs ATF6 activation without altering IRE1 or PERK signaling, resulting in increased sensitivity to ER stress-induced apoptosis. Mechanistically, we identify TMED9 as a stress-induced stabilizer of ATF6 that prevents its ubiquitin-dependent proteasomal degradation. Functionally, TMED9 regulation is exploited by tumor cells, which sustain IRE1-XBP1s activity to upregulate TMED9, thereby enhancing survival under ER stress conditions. Collectively, our findings establish TMED9 as a critical regulator of ER stress adaptation. TMED9 emerges as a molecular mediator that links IRE1-dependent transcriptional response to ATF6 stabilization, ultimately supporting increased secretory demand under stress conditions and in cancer development.\n\nID: 42057546\nTitle: mTOR Signalling in Neurodegenerative Disorders: Unveiling Key Factors, Mechanistic Insights, and Possible Therapeutic Interventions.\nAbstract: Neurodegenerative diseases (NDDs) are defined by the gradual degeneration of neuronal cells, wherein the accumulation of misfolded proteins can lead to memory impairments, motor dysfunctions, and other deteriorations. Despite the widespread impact, there are currently no viable pharmaceuticals to treat these disorders. The mTOR protein is a crucial regulator of cell survival, growth, autophagy, and apoptosis. Targeted modulation of mTOR signaling holds promise for mitigating neurodegeneration in Alzheimer's, Huntington's, ALS, and Parkinson's disease. Understanding its interactions with pathways such as PI3K/Akt, AMPK, and SIRT1 is essential for developing effective therapeutics.\n\nID: 42055490\nTitle: Raloxifene Beyond Osteoporosis: Unlocking Neurorestoration Through Remyelination, Inflammatory Regulation, and Neuroimmune Modulation in CNS Pathologies.\nAbstract: Raloxifene, a selective estrogen receptor modulator (SERM), has emerged as a promising candidate for repurposing in neurodegenerative and neuropsychiatric disorders. Traditionally approved for osteoporosis and breast cancer prevention, its tissue-selective estrogen receptor modulation underpins its potential therapeutic applications. This review critically examines the pharmacological, preclinical, and clinical evidence supporting raloxifene's neuroprotective and neuropsychiatric effects, as well as its mechanisms of action, safety profile, and clinical limitations. Raloxifene exerts neuroprotective effects by targeting estrogen receptors, including ER\u03b1, ER\u03b2, and GPER, modulating genomic and non-genomic pathways. These pathways regulate oxidative stress, mitochondrial stability, neuroinflammation, and apoptosis-core features of neurological disorders such as Alzheimer's (AD), Parkinson's (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS). Preclinical studies demonstrate raloxifene's ability to reduce amyloid-\u03b2 aggregation in AD, protect dopaminergic neurons in PD, mitigate demyelination in MS, and decrease protein aggregation in ALS. Additionally, raloxifene exhibits positive effects on memory, attention, and negative symptoms in schizophrenia, alongside antidepressant and anxiolytic properties. Although promising, raloxifene's clinical translation faces challenges. Existing trials are limited by small sample sizes, heterogeneous designs, and a lack of long-term data. Most studies focus on postmenopausal women, leaving gaps regarding effects in men, premenopausal women, and younger populations. Furthermore, discrepancies between preclinical and clinical dosing complicate its therapeutic optimization. Future research should explore sex-specific effects, optimize CNS-targeted dosing strategies, and employ biomarkers for neuroprotection and inflammation. Long-term trials are essential to evaluate its disease-modifying potential. Raloxifene represents a promising repurposing candidate for CNS disorders, however, its therapeutic role remains to be established through robust clinical validation.\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: 41997149\nTitle: SARM1 executes neuronal parthanatos and promotes excitotoxic cell death.\nAbstract: The nicotinamide adenine dinucleotide (NAD+) hydrolase sterile alpha and Toll/interleukin-1 receptor motif-containing 1 (SARM1) is the central executioner of pathological axon degeneration and is allosterically activated by an increased nicotinamide mononucleotide (NMN)/NAD+ ratio. DNA damage induces NAD+ loss and an increased NMN/NAD+ ratio by hyperactivating poly(ADP-ribose) polymerase 1 (PARP1), which triggers the parthanatos cell death pathway. Multiple mechanistically distinct DNA-damaging agents activate SARM1 and induce axon degeneration following PARP1 activation. Remarkably, SARM1 is required for key steps downstream of hyperactivated PARP1, which are pathognomonic of parthanatos, including mitochondrial depolarization, nuclear translocation of apoptosis-inducing factor (AIF), and cell death. Hence, SARM1 is an essential component of neuronal parthanatos. Moreover, complex neurodegenerative stimuli whose mechanisms include activation of parthanatos, such as 1-methyl-4-phenyl-pyridinium (MPP+) dopaminergic neuron toxicity and N-methyl-D-aspartate (NMDA) excitotoxicity, are potently protected by SARM1 inhibition. These findings place SARM1 at the nexus of multiple mechanisms driving neuronal cell death, thereby greatly expanding the potential clinical utility of SARM1 inhibitors beyond diseases of axon loss.\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.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"How does karyoptosis occur compared to apoptosis? SOD1 seems to be associated with apoptosis in some ALS phenotypes, but is SOD1 associated with ALS pathological karyoptosis as well?\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis evaluates the mechanistic differences between apoptosis and karyoptosis within the context of amyotrophic lateral sclerosis (ALS). It investigates the functional role of superoxide dismutase 1 (SOD1) in both regulated cell death pathways to determine if SOD1 pathology extends to karyoptotic neuronal death.\n\n### [INTRODUCTION & JUSTIFICATION]\nApoptosis and karyoptosis represent distinct cellular death modalities. Apoptosis is a well-characterized programmed cell death pathway, whereas karyoptosis is identified as a unique mechanism induced specifically by proteotoxic stress, characterized by nuclear degeneration and the cellular expulsion of nuclear material. Karyoptosis is mechanistically regulated by the p38 kinase signalling pathway, which modulates the stability of LaminB1 via direct phosphorylation. In contrast, apoptosis is frequently triggered by factors such as mitochondrial dysfunction, reactive oxygen species (ROS) accumulation, and dysregulated signaling axes.\n\nEvidence confirms that SOD1 is heavily implicated in ALS pathophysiology, both as a causal mutation and as a protein prone to toxic aggregation. SOD1 mutations are linked to apoptosis through pathways involving the BAX/Bcl-2 ratio, caspase-3 activation, and oxidative stress. Regarding karyoptosis, evidence indicates that karyoptotic features are present in ALS/FTD models where proteotoxic stress is the primary driver. While SOD1 aggregation is a classic hallmark of ALS pathology, its specific involvement as a direct mediator of the p38/LaminB1-driven karyoptotic pathway requires further specific mechanistic studies beyond the general understanding that proteotoxic stress\u2014often exacerbated by mutant proteins\u2014initiates karyoptosis. The literature establishes that karyoptotic features are observable in ALS/FTD contexts, providing a plausible, though not explicitly confirmed, intersection between SOD1-mediated proteotoxicity and karyoptotic death.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Karyoptosis involves the direct expulsion of nuclear material, a morphological hallmark distinct from the apoptotic condensation patterns.\n* The p38 kinase pathway acts as a regulatory node for karyoptosis by modulating LaminB1 stability.\n* SOD1 aggregates in myelinic nanochannels contribute to oligodendrocyte-mediated axonal support loss, distinct from neuronal death.\n* Mutations in SOD1 directly destabilize the local protein structure, promoting $\\beta$-sheet-driven amyloid fibrillation.\n* Oxidative stress serves as a common upstream signal for both apoptosis and other cell death pathways, including PARP1-dependent parthanatos.\n* SARM1 is required for neuronal parthanatos, effectively bridging DNA damage-induced NAD+ loss and cell death.\n* COMMD1 knockdown enhances copper incorporation into SOD1, providing a potential strategy to prevent misfolding-induced apoptosis.\n* Karyoptotic death has been identified in post-mortem tissues of patients with FTD and Alzheimer's disease.\n* Proteasomal degradation of CHK1 in cells with TDP-43 or FUS inclusions links DNA damage accumulation to ALS pathogenesis.\n* Spatial sampling bias in spinal cord segments accounts for significant variability (60%) in reported motor neuron loss in ALS models.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Most forms of ALS associated with a suspected causal variant are inherited in an autosomal dominant manner. However, there is an important subset of autosomal recessive (AR) variants, often associated with early-onset or atypical clinical features. Advances in genetic sequencing have led to increased recognition of AR ALS. In this review, we focus on four key confirmed AR ALS-associated genes, which appear to be most common-ALS2, SPG11, OPTN, and the D90A variant of SOD1-reviewing their pathophysiology and unique clinical manifestations. We also highlight very rare AR mutations implicated in ALS, including SYNE1, ATP13A2, and FUS, and some associated with overlap syndromes or debated pathogenicity including SIGMAR1, ERLIN1, and ERLIN2. These genes are involved in an array of processes including axonal transport, endosomal trafficking, oxidative stress response, and autophagy, suggesting distinct mechanisms of motor neuron degeneration. Some forms of AR ALS more frequently present with juvenile onset and slower progression, but other genes are associated with broader phenotypic spectra. This includes overlap with hereditary spastic paraplegia (HSP) and hereditary ataxias. Understanding these AR forms of ALS may enhance diagnostic precision, improve prognostication, and may pave the way for targeted gene therapies. This review underscores the emerging significance of AR inheritance in ALS and calls for deeper investigation into its molecular and clinical dimensions.",

In this study, we investigated the pathological role of microRNA-485-3p (miR-485-3p) in ALS, particularly its regulation of PGC-1\u03b1, a transcriptional coactivator essential for mitochondrial function and neuroprotection. We also evaluated the therapeutic potential of BMD-001S, a nanoparticle-based formulation encapsulating an antisense oligonucleotide targeting miR-485-3p. Our results demonstrated that miR-485-3p expression was significantly elevated in both SOD1G93A-expressing HMC3 microglial cells and in the spinal cords of SOD1G93A transgenic mice at late disease stages, implicating its contribution to ALS pathogenesis. Intravenous administration of BMD-001S effectively reduced miR-485-3p levels and restored PGC-1\u03b1 mRNA and PGC-1\u03b1 protein expression in the spinal cord. These molecular changes were associated with notable therapeutic outcomes, including reduced SOD1 protein aggregation, decreased neuroinflammation, and lower neurofilament light chain concentrations in cerebrospinal fluid. Moreover, BMD-001S treatment was associated with improvements in electrophysiological parameters and preservation of neuromuscular junction integrity during the observation period in SOD1G93A transgenic mice. Taken together, these findings suggest that miR-485-3p/PGC-1\u03b1 pathway is a promising therapeutic target in ALS and support the potential of BMD-001S as a novel treatment strategy for the disease.",
"41599384": "ID: 41599384\nTitle: Standardized Hydroxytyrosol-Enriched Olive Pomace Juice Modulates Metabolic and Neurotrophic Signaling Pathways to Attenuate Neuroinflammation and Protect Neuronal Cells.\nAbstract: Olive pomace (OP), a by-product of olive oil production, is a sustainable resource rich in bioactive compounds with potential applications in cosmetics and pharmaceuticals. This study investigates the protective effects of olive pomace juice (OPJ) against H2O2-induced neuronal damage and LPS-induced inflammatory responses in HT22 and BV2 cells, respectively. OPJ suppressed H2O2-induced cell death and exerted anti-apoptotic effects by reducing the BAX/BCL2 ratio and caspase-3 cleavage. OPJ also mitigated neurodegenerative hallmarks by decreasing amyloid fibrils formation and inhibiting \u03b2-secretase and acetylcholinesterase (AChE) activity. Mechanistically, OPJ enhanced antioxidant response by upregulating Nrf2 and its downstream molecule HO-1, along with increasing mRNA levels of antioxidant enzymes, including catalase, SOD1, and GPx. OPJ further activated AMPK\u03b1-SIRT1-PGC1\u03b1 signaling and CREB-BDNF-TrkB signaling, suggesting modulation of key antioxidant, anti-apoptotic, and neurotrophic pathways. In BV2 cells, OPJ downregulated pro-inflammatory cytokines (IL-6 and IL-1\u03b2) and decreased iNOS and COX-2 expression through suppression of NF-\u03baB and MAPK signaling pathways. HPLC analysis identified hydroxytyrosol (10.92%) as the major active compound in OPJ, which compared with tyrosol (2.18%), and hydroxytyrosol exhibited greater neuroprotective and anti-inflammatory effects than tyrosol. This study highlights the potential of OPJ and its major compound, hydroxytyrosol, as functional agents for mitigating neurodegeneration-related cellular response, supporting its application in the food and pharmaceutical industries.",
"41601590": "ID: 41601590\nTitle: Apolipoprotein A1 reduces blood-spinal cord barrier leakage, improves astrocytic coverage, and enhances motor neuron survival to restore the neurovascular unit in ALS mice.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive, age-related motor neuron degenerative disease with multiple causal factors. Dyslipidemia has been identified as an important pathological element. Impaired lipid protein metabolism manifests in ALS patients and in an ALS mouse model. Apolipoprotein components are the primary regulators of plasma lipid metabolism. Apolipoprotein A1 (ApoA1), a high-density lipoprotein, acts as an antioxidant and reduces inflammation, preventing blood vessel injury. However, the effects of ApoA1 upon the ALS-damaged endothelium in the CNS are unknown. The objective of the study was to determine the effect(s) of injecting ApoA1 into G93A SOD1 mice at the early symptomatic stage. A single dose of ApoA1 or media was systemically administered into 13-week-old G93A SOD1 male and female mice. Body weight and tests of motor function were evaluated weekly for 4\u202fweeks post-injection. Permeability of spinal cord capillaries was determined by Evans blue (EB) fluorescent dye injected into mice at 17\u202fweeks of age. Immunohistochemical analyses determined the statuses of glial cells and ApoA1 distributions in ALS mice cervical/lumbar spinal cords. Motor neurons in cervical/lumbar spinal cord ventral horns of ApoA1-treated and media-injected ALS mice were stained with cresyl violet for histological analyses. ApoA1 injected into G93A SOD1 mice at the early symptomatic stage significantly benefited both male and female animals by (1) delaying behavioral disease progression; (2) reducing EB capillary leakage into spinal cord parenchyma; (3) lessening astrogliosis and microgliosis; (4) protein incorporation into capillary endothelium and motor neurons; and (5) improving survival of motor neurons in the spinal cord. Our novel data showed that systemically administered ApoA1 benefited ALS mice of both sexes, likely by beneficial effects on damaged microvessels, possibly engendering restoration of neurovascular unit integrity. Moreover, an anti-inflammatory ApoA1 effect was demonstrated by the reduction of glial cell activation, potentially mitigating vascular injury. The results of our preclinical study suggest that ApoA1 may be a potential protein-mediated therapeutic for restoring vascular function. Our novel strategy may lead to future clinical trials, furthering our goal of effectively treating ALS patients.",

Using the sod-1 A4VM amyotrophic lateral sclerosis (ALS) model in Caenorhabditis elegans, we investigated the protective effects of the probiotic Enterococcus faecium against oxidative stress-induced neurodegeneration. Animals fed E. faecium showed reduced motor neuron degeneration under oxidative stress compared to those maintained on a standard Escherichia coli diet. Transcriptome analysis revealed a significant enrichment of oxidoreductase genes, including cytochrome P450 (cyp) genes. RNAi-mediated knockdown of cyp genes impaired E. faecium-mediated neuroprotection, and this loss correlated with increased reactive oxygen species (ROS) levels. We identified the conserved nuclear hormone receptor NHR-86 as a key regulator of cyp gene expression and neuroprotection. Loss of nhr-86 abolished the probiotic's protective benefits, while transgenic expression of nhr-86 restored cyp induction and neuronal resilience. Importantly, intestinal expression of NHR-86 was sufficient to restore CYP induction and neuronal resilience, whereas neuronal knockdown had no effect, indicating that gut NHR-86 activity is essential for this protective pathway. These findings reveal a previously uncharacterized NHR-CYP regulatory axis activated by an intestinal probiotic, highlighting a mechanistic link between microbial signals and host neuroprotection.",

While ALS is characterised by rapidly progressive motor neuron degeneration, leading to severe complications and death, CMT as a peripheral neuropathy is less severe, and patients have a longer life span, although with a compromised quality of life. Despite their clinical differences, current knowledge suggests that familial ALS (fALS) and CMT may share common genetic and molecular mechanisms. We aimed to identify shared genes mutations and molecular pathways between fALS and CMT through a literature and database search. Thirteen genes were identified, involved in distinct cellular processes: axonal transport (DYNC1H1, KIF5A, SPG11, DCTN1), protein homeostasis (NEFH, VCP, SOD1), RNA metabolism (GARS, SETX), cellular stress response (HSPB1, FIG4), and mitochondrial function (MFN2, CHCHD10). While these linkages to the two diseases are rare for each gene, understanding possible mechanistic commonalities at the molecular level can initiate new research directions, help in identifying additional common genes between neurodegenerative disorders, and improve diagnostics.",

In this study, we established a robust aging model by synergistically combining d-galactose and acute gamma-irradiation (6\u2009Gy), intensified senescence-associated phenotypes in rat brain tissue. Rats were divided into four groups: Group I: negative control; group II (naringin-treated): rats were given naringin (50\u2009mg/kg; p.o.) for 1 week; group III (Rad+ D-galactose): rats were exposed to whole-body gamma radiation (6\u2009Gy) and then received D-galactose (300\u2009mg/kg b. wt. i.p.) for 7 days; group IV (Rad+ D-galactose+ naringin): as in group III, then naringin (50\u2009mg/kg b. wt. p.o.) for 1 week. This model exhibited elevated levels in IL-6, TNF-\u03b1, p16INK4A, p21CIP1 and retinoblastoma protein (Rb) levels, as well as upregulated NF-\u03baBp65 protein expression in brain tissue. Remarkably, naringin supplementation reversed the pathological signatures, restoring antioxidant balance, suppressing inflammatory mediators, and modulating apoptotic pathways. Histological hallmarks such as gliosis, neurophagia, and pyknosis, as well as immunohistological staining of caspase-3 and p53 expression, confirmed the aforementioned consequences. Collectively, these findings highlight naringin's therapeutic potential in mitigating brain aging by targeting oxidative stress, inflammation, and apoptosis. This study offers a robust experimental framework for investigating senescence and supports naringin as a promising candidate for intervention in age-related neurodegenerative disorders.",
"41651252": "ID: 41651252\nTitle: Novel extracellular vesicle release pathway facilitated by toxic superoxide dismutase 1 oligomers.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that results in paralysis and death within three to five years. Mutations in over forty different proteins have been linked to ALS, raising debate over whether ALS is a single disease or multiple disorders with similar symptoms. Mutations in Cu,Zn superoxide dismutase 1 (SOD1) are found in only 2-3% of ALS cases, yet misfolded SOD1 appears in both sporadic (sALS) and familial (fALS) patients. Furthermore, mutations in TDP-43 or FUS increase levels of misfolded SOD1 on extracellular vesicles (EVs). Small EVs isolated from ALS patient samples have been shown to cause death of wild-type motor neurons and myotubes, supporting the theory that EVs play a role in spreading disease. We hypothesize that the previously identified toxic trimeric SOD1 spreads via EVs in ALS and influences the distribution of other ALS-related proteins, suggesting a common mechanism. To test this, we isolate EVs from motor neuron-like cells expressing mutations that stabilize trimers. We then perform a sandwich enzyme-linked immunosorbent assay (ELISA) using a CD9 capture antibody to measure whether misfolded SOD1 and 17 other ALS-related proteins increase or decrease on EVs with trimer stabilization. We identify which EV release pathway is affected by trimeric SOD1 using endocytosis and exocytosis inhibitors and analyze altered protein interaction pathways through co-immunoprecipitation and mass spectrometry proteomics. Our results show that VAPB, VCP, and Stathmin-2 increase on EVs when trimers are stabilized. The common pathway linking these ALS-associated proteins and SOD1 appears to involve multiple mechanisms, including the Caveolae endocytosis pathway, pointing to a novel hybrid EV release pathway in ALS. Overall, our findings show that trimeric SOD1 influences EV cargo and spread in ALS.",
"41664997": "ID: 41664997\nTitle: N-Truncated Superoxide Dismutase-1 in Cerebrospinal Fluid Is Folded and Active.\nAbstract: Mutations in the antioxidant enzyme superoxide dismutase-1 (SOD1) are a well-established cause of amyotrophic lateral sclerosis (ALS). The mutations promote SOD1 misfolding, resulting in protein aggregation and motor neuron degeneration. SOD1 is normally a structurally stable enzyme, and the mechanisms underlying SOD1 misfolding remain poorly understood. Approximately one third of SOD1 in cerebrospinal fluid (CSF) exhibits an N-terminal truncation, the biological significance of which remains unclear. This is remarkable given the dramatic effects ALS-linked C-terminal truncations have on the enzyme. In this study, we identified the truncation site and investigated its impact on SOD1 stability and enzymatic activity. Edman degradation revealed the cleavage site between Asn-26 and Gly-27, generating a 26-residue peptide that was confirmed by mass spectrometry. We analyzed postmortem tissues from different parts of the central nervous system (CNS), including the choroid plexus, and found only trace amounts of N-terminally truncated SOD1. Biochemical characterization of the SOD1 in CSF was done by size exclusion chromatography, ion exchange chromatography, and mass spectrometry. Our findings demonstrate that SOD1 in CSF retains full enzymatic activity, that the N-terminally truncated variant is mainly present in heterodimers with native SOD1 subunits, and that the dimer remains folded and active, with both fragments of the truncated SOD1 fixed after proteolysis. Truncated SOD1 was absent in human plasma. In mice, only transgenically expressed human SOD1 underwent truncation in CSF, whereas endogenous murine SOD1 remained intact. Lastly, the N-terminal truncation does not induce misfolding, unlike the destabilizing effects observed with C-terminal truncations. The location where the truncation takes place and the underlying mechanism could not be identified. Whether the N-truncated SOD1 variant contributes to ALS pathogenesis remains to be determined.",

We describe four patients with hereditary ALS caused by the p.Gly94Ser SOD1 mutation who were treated monthly with the intrathecal antisense oligonucleotide tofersen in a clinical setting at Landspitali University Hospital of Iceland. After initiating treatment 15-26\u00a0months ago, no significant clinical deterioration was observed, and three patients showed signs of clinical improvement, with some recovery of motor function. All four patients currently present with chronic nonprogressive ALS, a phenotype not previously observed or documented. Concomitantly, the concentration of neurofilament light chain (Nf-L) in the cerebrospinal fluid decreased to the normal range. This clinical benefit and decrease in Nf-L levels were detected regardless of the patient's initial ALSFRS-R score. No serious adverse events were observed. Notably, we observed a clinically meaningful effect in two patients who had been ill for several years before treatment was instituted, raising questions about who should receive treatment and the biology of paresis and motor neuron cell loss in patients with ALS. Although only a minority of ALS patients carry a SOD1 mutation, the advent of this new precision medicine has profound implications for ALS management.",
"41686369": "ID: 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.",
"41702846": "ID: 41702846\nTitle: Efficient induction of motor neuron disease in transgenic G93A SOD1 mice by prion-like seeding.\nAbstract: Mutations in superoxide dismutase 1 (SOD1) cause paralysis in familial amyotrophic lateral sclerosis and promote its misfolding into neurotoxic aggregates. Previous studies have shown that mice expressing the ALS-causing G85R variant of SOD1 develop paralysis much faster after intraspinal injection of spinal homogenates from paralysed G85R SOD1 mice. These findings, and other studies in cell models, established the prionoid templating properties of misfolded mutant SOD1. Previously, however, we noted that the widely used Gur1-G93A SOD1 mice, which express at high levels and develop paralysis by 6\u2009months of age, were resistant to seeding by homogenates from paralysed G93A mice. A line of G93A mice that expresses at very low levels (VLE-G93A) was responsive to seeding but at low efficiency. The poor susceptibility of G93A-SOD1 mice to seeding was not what we expected if prion-like propagation is essential to SOD1 ALS pathogenesis. In our prior studies, seeding homogenates from paralysed G93A-SOD1 mice were injected into the spine of newborn mice, leading us to question whether older G93A SOD1 mice might be more susceptible to seeding. Here, we establish that adult VLE G93A SOD1 mice (up to 12\u2009months of age) injected intrathecally with seeding homogenates containing misfolded G93A or G85R SOD1 developed accelerated motor neuron disease efficiently. Thus, we demonstrate that both the route and age of inoculation can influence the efficiency of SOD1 seeding to induce motor neuron disease in VLE G93A-SOD1 mice. These data, together with our earlier reports, suggest that prion-like templating contributes to disease progression in SOD1-ALS.",

Neuroinflammation represents a central pathogenic mechanism in ALS, yet the upstream molecular regulators that integrate multiple inflammatory cascades remain poorly understood. Here, we investigated whether Bruton's tyrosine kinase (BTK), which integrates DNA-sensing and Toll-like receptor signals upstream of the cGAS-STING-NF-\u03baB cascade, serves as a key regulatory node in ALS pathogenesis. Public RNA-seq datasets of motor neurons and post-mortem tissues from ALS patients were utilized to identify BTK expression patterns. SOD1-mutant human induced pluripotent stem cells (hiPSC) were differentiated into motor neurons (hiPSC-MNs) and microglia (hiPSC-MGs). NF-\u03baB dysregulation was profiled by scRNA-seq (hiPSC-MGs) and bulk RNA-seq (hiPSC-MNs). DNA damage (\u03b3H2AX), inflammatory signalling (western blot/ELISA) and phagocytosis (pH-rodo uptake) were quantified, and MG-conditioned medium was tested for MN toxicity. Monocultures and MN-MG co-cultures received zanubrutinib (3 \u00b5M, 12 h). SOD1-G93A mice were administered zanubrutinib (30 mg/kg, daily) from 2.5 months; motor performance, survival, spinal histology and PI3K-AKT-mTOR activity were assessed after 2 months of treatment. ALS spinal cord and cortex tissues of patients, as well as SOD1-mutant hiPSC-MGs and hiPSC-MNs, demonstrated elevated BTK phosphorylation with increased p-STING, p-TBK1, and nuclear NF-\u03baB accumulation. ALS hiPSC-MGs exhibited inflammatory activation, NLRP3 induction, and impaired phagocytosis, while ALS hiPSC-MNs showed DNA damage and caspase-3-mediated apoptosis. Conditioned medium from inflammatory microglia amplified neuronal STING-NF-\u03baB activity and apoptosis, demonstrating non-cell-autonomous toxicity. The STING inhibitor H-151 reduced neuronal p-STING/p-TBK1/NF-\u03baB and apoptosis, confirming pathway causality. Pharmacological BTK inhibition reduced DNA damage in ALS hiPSC-MNs by 61.4% (p<0.05), restored phagocytosis in ALS hiPSC-MGs to 87.2% of control levels (p<0.01), and prevented neuronal apoptosis induced by microglial conditioned medium. In SOD1-G93A mice, BTK blockade extended median survival from 158 to 173 days (p<0.01, log-rank test), improved motor function, and attenuated neuroinflammation while moderately rebalancing PI3K-AKT-mTOR signaling without impairing autophagy-lysosome dynamics. We identify BTK as a critical upstream regulator of the dysregulated cGAS-STING-NF-\u03baB signalling axis characteristic of ALS pathogenesis. BTK orchestrates both cell-autonomous dysfunction in motor neurons and non-cell-autonomous toxicity through microglial activation, representing a convergent regulatory node that integrates multiple pathogenic pathways. These mechanistic insights provide a molecular framework for understanding ALS neuroinflammation and establish a rational basis for BTK-targeted therapeutic intervention in neurodegeneration.",
"41723979": "ID: 41723979\nTitle: Allicin improves motor neuron survival in amyotrophic lateral sclerosis by reducing neuroinflammation and modulating gut microbiota.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of motor neurons (MNs). Allicin, a defensive molecule in garlic with anti-inflammatory and gut microbiota-modulating properties, has shown therapeutic potential in animal models of various diseases including Alzheimer's disease (AD). However, its possible therapeutic role in ALS remains unclear. The purpose of this study is to investigate the therapeutic effect of allicin in ALS transgenic SOD1G93A mice. Starting at 60 days of age, SOD1G93A mice received oral gavage of allicin (10\u202fmg/kg) on alternate days, while the control group received an equal volume of normal saline (NS) on the same schedule. Twelve mice per group were used for monitoring disease onset and survival. Nissl staining and choline acetyltransferase (ChAT) immunofluorescence were used to quantify MNs in the anterior horn. Microglial activation was analyzed by immunofluorescence staining for Iba1, ARG1, and CD86. The mRNA expression levels of IL-10, TGF-\u03b2, IL-1\u03b2, and TNF-\u03b1 were examined using qPCR. Additionally, fecal samples were collected for 16S rDNA sequencing to evaluate changes in gut microbiota composition. We observed that allicin treatment failed to prolong the onset time and survival period of SOD1G93A mice, but it extended the disease duration. Nissl staining analysis revealed that allicin treatment delayed the loss of spinal MNs, a finding corroborated by ChAT immunofluorescence. Furthermore, allicin treatment significantly reduced neuroinflammation and improved gut microbiota. Taken together, although allicin may prolong disease duration in ALS, it did not improve overall survival or delay disease onset. Therefore, its potential disease-modifying effects require further validation.",

Among the key mechanisms implicated in ALS pathogenesis, neuroinflammation and oxidative stress have emerged as prominent contributors to disease progression. This systematic review with meta-analysis involved 344 preclinical studies conducted on SOD1 animal models of ALS, to quantitatively evaluate the effects of treatments targeting neuroinflammation and oxidative stress on functional outcomes such as disease onset, survival, motor neuron degeneration, and locomotion. Data extraction and validation were performed using a combination of a large language model and human review. Results show that while most interventions led to reduced astrogliosis, M1 microgliosis, and oxidative stress, and increased M2 microgliosis, these effects were more strongly associated with improved survival and motor outcomes than with delayed disease onset. The analysis also revealed that treatment timing significantly influences outcomes, with interventions initiated during the late pre-onset window showing the highest efficacy. Furthermore, sex differences were noted, with male mice displaying better outcomes in progression metrics but worse in the age at onset. Overall, this meta-analysis indicates that inflammation and oxidative stress are important contributors to ALS progression in SOD1 animal models, identifies potentially critical therapeutic windows, and supports the consideration of sex-balanced and stage-specific treatment strategies at the preclinical level.",

Mesenchymal stem/stromal cells (MSCs) have been reported to exert neuroprotective effects in models of injury and disease, acting primarily through release of small extracellular vesicles (sEVs). MSC-derived sEVs (MSC-sEVs) have therefore attracted attention as a potential cell-free therapeutic approach for treating neurological conditions such as ALS. Because MSC-sEVs can cross both the nasal epithelial barrier and blood-brain barrier to reach the central nervous system (CNS), intranasal administration represents an attractive approach for repeated delivery of MSC-sEVs for long-term administration. In this study, we administered bone marrow-derived MSC-sEVs or vehicle intranasally to a SOD1(G93A) transgenic mouse model of ALS; the large majority of the sEVs had surface markers for exosomes. Dosing was for three consecutive days per week beginning one day after onset of neurological symptoms and continuing until a moribund state. Neurological score and body weight were recorded daily. Although total survival time and post-onset survival duration were not significantly prolonged by MSC-sEV treatment, MSC-sEV treatment significantly delayed progression from a mild symptom phase (NeuroScore 1) to more severe symptoms (NeuroScore 2) compared with vehicle-treated controls and showed a trend toward slower weight loss. These findings indicate that intranasal administration of MSC-sEVs can delay functional deterioration and prolong the mild impairment stage in an ALS mouse model. If translatable to human patients, such preservation of neurological function could represent a clinically meaningful outcome.",

Evidence has shown that degeneration of cutaneous nerves may reflect neurodegenerative processes occurring within the central nervous system. Although skin biopsy is widely adopted in clinical practice, the procedure is invasive and requires multiple patients' tissue removals. Therefore, we developed a 3D innervated skin model by combining 3D printing of methacrylated hyaluronic acid as an innovative tool for better reproducing the dermis and epidermis and electrospinning of polylactic acid for mimicking skin innervation. Later, 3D artificial skin was colonized with a preneuronal cell line (SH-SY5Y) and fibroblasts isolated from skin biopsy of ALS patients at different disease stages. 3D skin possesses a porosity suitable for cell colonization and a high stability. Importantly, biological results reveal an increase of TAR DNA-binding protein 43 aggregates, NOD-like receptor pyrin domain containing protein 3, interleukin (IL)-18, IL-6, and nitrites in 3D skin of ALS patients, thus indicating pyroptosis activation linked to neurodegeneration. This physiologically relevant 3D skin model reduces the need for repeated biopsies, allows standardized experimental conditions, and supports biomarker research and preclinical drug testing in ALS.",

However, the mechanism by which TDP-43 pathology disrupts microglial function and drives neuroinflammation remains unclear. In this study, we demonstrated that cytoplasmically mis-localized TDP-43 exacerbated neuroinflammation, induced cell death, and impaired phagocytic function in microglial cells, primarily through receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis. Pharmacological inhibition of RIPK3 with GSK872 markedly attenuated these pathological effects in vitro. These findings were further corroborated in a murine model with cytoplasmic TDP-43 mis-localization, where GSK872 treatment remarkably alleviated neuroinflammation and restored cognitive deficits. Mechanistically, our findings indicate that the nuclear depletion of TDP-43, resulted from its cytoplasmic mis-localization, impairs its ability to transcriptionally repress the Ripk3 gene, subsequently leading to RIPK3 upregulation and activation of RIPK3-dependent necroptosis. Collectively, our findings establish RIPK3-dependent necroptosis as a critical driver of TDP-43 pathology-mediated neuroinflammation and identified necroptosis as a promising therapeutic target in TDP-43-associated neurodegenerative disorders.",

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.",

Although the precise pathogenesis of such diseases is complex and multifactorial, several molecular pathways have been implicated, including the aggregation of misfolded proteins, mitochondrial dysfunction, oxidative stress, neuroinflammation and disrupted iron homeostasis. Emerging evidence has underscored the pivotal role of ferroptosis, an iron\u2011dependent, non\u2011apoptotic form of cell death, in neurodegenerative disease progression. Ferritin, characterized by a 24\u2011subunit hollow sphere structure composed of heavy and light chains, plays a key role in the network regulating cerebral iron homeostasis. In response to cellular iron overload, ferritin expression is upregulated to sequester labile iron and mitigate Fenton reaction\u2011mediated toxicity, thus exerting a cytoprotective function. Paradoxically, ferritin can be degraded via ferritinophagy, a selective autophagic process that releases toxic ferrous iron and directly triggers ferroptosis. This review systematically reviews the role of ferritin within the iron homeostasis network to elucidate the connection between the dysregulation of iron metabolism and the pathological mechanisms of neurodegenerative diseases. The study focused on the potential role of ferritin as a biomarker for early diagnosis, therapeutic strategies targeting ferritin pathways to restore iron homeostasis and the clinical translational value of magnetic resonance imaging\u2011based non\u2011invasive quantification of cerebral iron deposition. It is crucial to elucidate the multidimensional roles of ferritin in neurodegeneration to provide a theoretical foundation for precision diagnostic and therapeutic approaches.",

UV light is well known for its risks on the skin and eyes. Recently, there has been growing interest in light at 405 nm (violet-blue light, VBL) due to its antimicrobial properties and perceived safety for mammalian cells when administered in controlled amounts. This research delved into the impact of 405 nm VBL on corneal and retinal pigment epithelial cell cultures. ARPE-19 and corneal BCE C/D 1b cells were exposed to VBL for varying doses, according at different exposure times, to evaluate cell viability, oxidative stress levels and apoptotic indicators. A 3D printed prototype with 14 LEDs centred at 405 nm wavelength was used to ensure uniform distribution of light during exposure. Cell viability was assessed using the MTT assay, measurement of oxygen species (ROS) production was carried out, and Western blot analysis was employed to study catalase and SOD-1 expression and apoptotic marker activation. Exposure to 405 nm VBL for both term (3 h) and prolonged durations (9 h) led to a weak decrease in cell viability in ARPE-19 cells, whereas the effect on BCE C/D 1b cells was negligible. There was no increase in ROS production, with catalase and SOD-1 expression remaining stable, suggesting no pro-oxidative stress effects in these models. Moreover, no activation of caspase-3 and accumulation of cytochrome C were found. Based on our results, exposure to 405 nm light at regulated levels does not pose a threat to the viability of the tested cell lines and does not lead to oxidative stress and apoptosis under these conditions. These results suggest a favourable cytocompatibility profile for these specific ocular cell models, laying a foundation for further investigations into its ocular safety.",

Beyond exporting Zn2+, recent evidence reveals that ZnT1 also transports Cu2+ and serves as a molecular hub linking zinc-copper interplay, redox balance, immune signaling and programmed cell death. This review summarizes current advances in ZnT1 structure, transport mechanism, regulatory networks and physiological roles across the gut-liver-immune-neuro-cardiovascular axis. We further outline its pathological involvement in Wilson disease, amyotrophic lateral sclerosis, cancer and inflammatory disorders, highlighting ferroptosis, cuproptosis and metabolic reprogramming as key downstream consequences of ZnT1 dysregulation. Emerging therapeutic approaches include small-molecule modulators, RNA-based regulation, antibody targeting and metal-based interventions. Although challenges remain-such as tissue specificity, systemic toxicity and biomarker development-ZnT1 is rapidly evolving from a basic transport protein to a promising precision medicine target. Continued efforts in structural biology, single-cell metallomics and targeted delivery systems will accelerate its clinical translation.",

The cardinal pathology of ALS is motor neuron-selective inclusion of proteins such as TDP43, SOD1, C9orf72-derived dipeptide repeats, or FUS due to the mutations in the genes encoding them. Both familial and sporadic forms of ALS also show neurofilament (NF) aggregates, attributed to an imbalance in subunit expression, particularly a decrease in neurofilament light chain (NF-L) levels. Current FDA-approved treatments extend survival for only a few months, highlighting the urgent need for new therapies. In this study, we developed a cell-based reporter system for high-throughput screening by engineering induced pluripotent stem cells (iPSCs) derived from ALS patients and differentiating them into spinal motor neurons. We screened over 6000 compounds using these reporter iPSC-derived motor neurons and identified a novel compound that increases NF-L expression by >50 %. However, this novel compound also inhibits TGF-\u03b2 signaling, prompting us to optimize its activity through a hit-to-lead chemistry analysis. In our subsequent investigations, we identified an additional compound that does not affect TGF-\u03b2 signaling and outperforms the original compound in both in vitro and in vivo drug metabolism and pharmacokinetics assays. Our study highlights the utility of iPSC-derived neurons in disease modeling and illustrates how they can be employed to discover new compounds for therapeutic development through extensive screening in disease-relevant settings.",

IRF5, a key regulator of inflammatory responses, is implicated in the disease mechanisms of various conditions. However, its mechanism in ALS remains unclear. This study found that IRF5 expression was significantly increased in hSOD1-G93A transgenic ALS mice and cell models, primarily localized in activated microglia. Silencing IRF5 altered microglial polarization, suppressed the release of inflammatory factors, enhanced phagocytic function, and reduced motor neuron apoptosis in a co-culture system. Mechanistic studies suggested that IRF5 may regulate microglial function through the NF-\u03baB signaling pathway. This study reveals the key role of IRF5 in microglia-mediated neuroinflammation and neuronal damage in ALS, indicating that targeting IRF5 could represent a promising treatment strategy for this disease.",

Here, we analyze longitudinally collected cerebrospinal fluid (CSF) samples from the phase 3 VALOR clinical trial to identify candidate tofersen treatment-response biomarkers in SOD1-ALS via quantitative proteomics. We observe significant modulation from baseline abundance for 56 proteins in tofersen-treated participants relative to placebo, including CSF GPNMB, which is significantly and continuously elevated across all post-baseline timepoints. We orthogonally confirm this observation by GPNMB immunoassay in independent tofersen-treated cohorts. Taken together, these data identify pharmacodynamic-response biomarkers of tofersen treatment that can be measured as early as 4 weeks post-treatment in SOD1-ALS patients and demonstrate the utility of leveraging unbiased proteomic screening integrated with targeted validation methods to identify pharmacodynamic-response biomarkers in clinical trial patient samples.",

Differentially expressed genes (DEGs) were identified using AD datasets GSE63061 and GSE63060 from the Gene Expression Omnibus. DEGs were intersected with mitochondria-related genes and programmed cell death-related genes to obtain DEGs (in AD) intersected with mitochondrial-related genes and DEGs (in AD) intersected with programmed cell death-related genes. Correlation analysis of these DEGs was used to identify candidate genes. Machine learning algorithms were applied to key genes, followed by functional enrichment, network construction, immune infiltration analysis, drug prediction, and expression validation. Two key genes, superoxide dismutase 1 (SOD1) and translocase of the outer mitochondrial membrane 7 (TOMM7), were identified and linked to pathways like ribosome and chemokine signaling. A strong positive correlation (0.76, P\u2005<\u2005.001) was found between them. Immune analysis showed differences in 11 immune cells between AD and controls, with TOMM7 positively linked to activated CD8 T cells and negatively to myeloid-derived suppressor cells. SOD1 and TOMM7 are regulated by 4 miRNAs and 71 long noncoding RNAs (lncRNAs). Seventeen potential AD drugs, including urea and nitric oxide, were predicted. Two key genes, SOD1 and TOMM7, related to mitochondria and PCD, were identified as potential targets for understanding AD's etiology, detection, and therapeutic approaches.",

METHODS: Early OA rat model was established by 4-week anterior cruciate ligament transection (ACLT). The radiomics was used to evaluate the relative damaged and undamaged area in OA patients\u2019 cartilage. We overexpressed and knocked down CILP in early OA chondrocyte to explore its potential mechanism. The quantitative proteomics was used to examine the protein profiles of the CILP-treated chondorcyte. The Yeast One-Hybrid Assay, Co-Immunoprecipitation (Co-IP), Nrf2 cytosol-nuclei fractionation and ubiquitination assay were used to investigate the potential mechanism in CILP intervention. Western blot, ROS, JC-1, Ferrous ion, MDA and GSH detection, transmission electron microscopy (TEM) were used to explored the therapeutic effect of CILP on OA. RESULTS: Moderate exercise up-regulates CILP in the articular cartilage intermediate zone. CILP recovers the ratio of type II / I collagen, Sox9, \u03b1-SMA expression and competitively bind to Keap1 protein and reduce the stability of Keap1-Nrf2 dimer, thereby reducing the degree of Nrf2 ubiquitination and promoting Nrf2 nuclear translocation. Nrf2 nuclear translocation activated SLC7A11, HO-1, GPX4 and SOD-1 expression, then decreased the MDA contents, but increased GSH content, which ultimately inhibited chondrocytes ferroptosis and promoted hyalinization of fibrocartilage. CONCLUSION: Exercise induced cartilage intermediate zone and CILP-Keap1-Nrf2 axis inhibits hyaline cartilage fibrosis and chondrocyte ferroptosis to alleviate early osteoarthritis.",
"41890274": "ID: 41890274\nTitle: Excitotoxicity in amyotrophic lateral sclerosis: a key pathogenic mechanism.\nAbstract: Amyotrophic lateral sclerosis is a complex neurodegenerative disease affecting motor neurons, characterized by the involvement of various factors, including oxidative stress, inflammatory processes, glutamate excitotoxicity, mitochondrial dysfunction, protein aggregation, axonal transport abnormalities, and apoptosis. The complexity of amyotrophic lateral sclerosis arises from its multifactorial aetiology involving diverse genetic, protein, metabolic, and cellular alterations. Mutations of different genes, such as SOD1, C9ORF72, TARDBP, and FUS, have been identified as critical contributors to disease pathophysiology through their facilitation of aberrant protein misfolding and aggregation. All these factors disrupt glutamate homeostasis, leading to calcium-mediated neurotoxicity. Under oxidative stress, motor neurons exhibit a diminished capacity to regulate calcium influx, along with impaired functioning of the mitochondria and endoplasmic reticulum, further compromising cellular integrity. Dysregulation of glutamate signalling also triggers astrocytic stress responses, leading to reduced glutamate clearance, thus worsening neuronal damage through excitotoxic mechanisms. These factors contribute to the excessive production of reactive oxygen species, which exacerbates glutamate imbalance and establishes a detrimental cycle of neuronal damage and glial dysfunction, ultimately intensifying excitotoxicity. This review aims to highlight the role of excitotoxicity in motor neuronal degeneration and to explore the molecular mechanisms underlying the pathogenesis of amyotrophic lateral sclerosis. It also examines current therapeutic approaches, including approved treatments and ongoing clinical trials to reduce excitotoxicity, while emphasizing the urgent need for novel, targeted strategies. Given the lack of definitive diagnostic tools and curative therapies, advancing our understanding of the molecular mechanisms driving excitotoxicity and neurodegeneration is, therefore, crucial for the development of more effective, disease-modifying treatments to slow amyotrophic lateral sclerosis progression.",
"41890591": "ID: 41890591\nTitle: Axonal transport impairment as an upstream mechanism in amyotrophic lateral sclerosis pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive loss of upper and lower motor neurons. Despite marked genetic and pathological heterogeneity, a unifying pathogenic framework remains lacking. We propose that axonal transport impairment represents an early and convergent but genotype-modulated upstream vulnerability in ALS, contributing to distal synaptic failure, bioenergetic stress, protein aggregation, neuroinflammation, and neuronal death. Across many ALS models, including SOD1, TARDBP (TDP-43), FUS, and C9orf72, transport deficits are frequently detectable in presymptomatic stages, often preceding overt motor neuron loss or clinical manifestation, although temporal ordering varies by molecular subtype. Human data from induced pluripotent stem cell-derived motor neurons and neuroimaging in mutation carriers further support early transport dysfunction in both familial and sporadic ALS. We synthesize genetic, cellular, and systems-level evidence demonstrating that diverse ALS-associated mutations converge on intracellular trafficking machinery through distinct but interacting mechanisms, disrupting long-range cargo delivery and clearance in motor neurons. This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation. This model generates testable predictions regarding presymptomatic transport biomarkers and the timing of therapeutic intervention. We discuss implications for biomarker development and therapeutic strategy, proposing restoration of axonal transport as a central component of rational multimodal disease modification in ALS.",
"41894255": "ID: 41894255\nTitle: Destabilized Soluble SOD1 Species as Potential Determinants of Disease Severity in Familial Amyotrophic Lateral Sclerosis.\nAbstract: Mutations in the Cu/Zn superoxide dismutase (SOD1) gene are linked to familial amyotrophic lateral sclerosis (ALS), yet the identity of the toxic molecular species remains unclear. We investigated the relationship between protein misfolding and pathogenicity by expressing GFP-tagged wild-type and mutant SOD1 (A4V, H46R, G93A) in mouse hippocampal HT22 cells. Western blotting under nonreducing conditions suggested that A4V, associated with rapid disease progression, was largely depleted of properly folded soluble SOD1 and instead produced highly destabilized soluble species. In contrast, H46R, associated with a milder phenotype, showed a moderate reduction in properly folded soluble SOD1 and generated partially folded/native-like conformers. G93A exhibited biochemical characteristics intermediate between those of A4V and H46R. A4V also showed a pronounced loss of GFP fluorescence, indicating severe structural destabilization; the extent of fluorescence loss in A4V, G93A, and H46R broadly correlated with clinical severity. Neither CuATSM nor ebselen\u2500targeting metal binding and disulfide formation, respectively\u2500rescued fluorescence, suggesting broader defects in SOD1 maturation. Nevertheless, both compounds inhibited ferroptosis, a nonapoptotic form of cell death characterized by iron-dependent lipid peroxidation, in HT22 cells, indicating alternative neuroprotective mechanisms. These findings identify destabilized soluble SOD1 species as a key toxic entity in ALS and highlight the utility of GFP-tagged constructs for evaluating folding status and screening therapeutic candidates.",
"41898728": "ID: 41898728\nTitle: Disturbances in Central Sensitization Are Associated with Disease Severity and Alterations in Gene Expression Measured in the Peripheral Blood Mononuclear Cells of Patients with Rheumatoid Arthritis.\nAbstract: Rheumatoid arthritis (RA) is a chronic autoimmune rheumatic disease of unknown etiolgy, characterized by erosive polyarthritis that leads to joint destruction and systemic inflammatory lesions in internal organs. Pain is a primary symptom of RA and a major contributor to psychological disturbances, which influence patients' subjective evaluation of their condition. These psychological issues may stem from disruptions in central pain regulation mechanisms, such as central sensitization (CS), which can also affect central metabolic processes. The objective was to investigate how the severity of central sensitization, measured by the Central Sensitization Inventory (CSI) questionnaire (Part 1), impacts clinical and neuropsychiatric parameters, as well as the expression of genes related to inflammation, tissue destruction, carbohydrate metabolism, and fatty acid metabolism in peripheral blood mononuclear cells (PBMCs) in patients with RA. Methods involved collecting blood samples from 59 RA patients (mean age 52.0 years). Clinical status was assessed using the DAS28 index and serum levels of CRP, ASPA, and RF. Neuropsychiatric parameters were evaluated through questionnaires measuring CS severity score (CSI), pain intensity (VAS, BPI), neuropathic pain (PainDETECT), anxiety and depression (HADS), fatigue (FSS, FACIT-F), fibromyalgia symptoms (FIRST), and pain catastrophizing. Protein expression in PBMCs was measured by ELISA, while gene expression was analyzed using quantitative real-time RT-PCR. All patients exhibited moderate to high disease activity. Participants were divided into four subgroups according to their CSI scores: subclinical (0-29 points), mild (30-39 points), moderate (40-49 points), and severe/extreme (50-100 points). Higher CSI scores correlated with significant increases in neuropsychiatric symptoms and a notable decrease in vitality. However, clinical parameters showed no significant differences among the subgroups. Gene expression analysis revealed upregulation of genes involved in the pentose phosphate pathway (G6PD), antioxidant defense (SOD1), fatty acid metabolism (FASN, CPT1B), apoptosis (CASP3), and tissue destruction and hypernociception (MMP-9) compared to healthy controls. The pro-inflammatory cytokine IL-1\u03b2 expression was comparable to controls, while TNF\u03b1 expression was elevated only in patients with severe/extreme CS scores. These findings suggest that CS-related disturbances may contribute to increased disease severity in RA, even in patients receiving active antirheumatic treatment. At the cellular level, disease severity appears linked to dysregulated expression of genes governing central metabolic processes, despite low expression of pro-inflammatory cytokine genes.",

Thus, novel synthetic quercetin derivatives (QDs) with improved properties and/or drug combinations should be designed and tested. In the present study, anticancer activity of fourteen newly synthesized QDs was investigated using four cellular models of melanoma, namely A375, MM370, G-361, and SH-4 cells. Thioquercetins (thioQ, thioQ(OAc)4, and thioQ(OAc)5), when used at low micromolar range, induced apoptotic cell death in melanoma cells compared to normal cells. Thioquercetins also reduced the population of spheroid-forming cells and suppressed the growth of A375 cells in 3D spheroid models. Thioquercetin-mediated antimelanoma action was potentiated upon heat shock protein 90 (HSP90) inhibition. Co-treatment with the HSP90 inhibitor 17-DMAG and thioquercetins augmented oxidative stress (increased superoxide production, decreased levels of antioxidant proteins SOD1, and PRDX1-2), and impaired the aryl hydrocarbon receptor (AhR)/cytochrome P450 1A1 (CYP1A1) signaling pathway-based detoxification of thioquercetins by the inhibition of AhR translocation to the nucleus and AhR-mediated stimulation of CYP1A1 expression leading to enhanced cytotoxic effects against melanoma cells. The senolytic activity of thioQ(OAc)4 with four acetylated hydroxy groups against cisplatin-induced senescent melanoma cells was also revealed in selected experimental settings. We suggest that the use of novel thioquercetin-based derivatives along with HSP90 inhibitors should be further validated in vivo and considered for the design of more effective antimelanoma strategies in the future.",

Epidemiological studies indicate geographical variations in incidence, and recent multi-omics evidence identifies a hypermetabolic state and mitochondrial dysfunction as key drivers of disease progression. The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2), which regulates antioxidant response and metabolism, represents a promising therapeutic target; however, the exploration of specific activators remains insufficient. This study evaluated the efficacy and mechanism of a novel KEAP1-NRF2 activator, MKL01351, in SOD1 G93A transgenic mice and NSC-34 motor neuron-like ALS models. Behavioral analyses demonstrated that MKL01351 significantly delayed disease onset, improved motor coordination in the rotarod and hanging tests, and extended survival. The compound alleviated oxidative stress by reducing malondialdehyde (MDA) levels and restoring the reduced glutathione/oxidized glutathione (GSH/GSSG) ratio, while also ameliorating the energy deficit by modulating glycolytic and mitochondrial functions, as confirmed by Seahorse analysis. Mechanistic investigations revealed that MKL01351 activated the NRF2 pathway, upregulating downstream targets such as NQO1 and HO-1, and specifically enhanced the expression of malic enzyme 1 (ME1). Loss-of-function experiments confirmed that ME1 knockdown abolished the protective effects, indicating that the NRF2-ME1 axis is a central hub for the synergistic regulation of metabolic and oxidative homeostasis. In conclusion, MKL01351 concurrently ameliorates oxidative stress and metabolic dysregulation via the NRF2-ME1 signaling pathway, offering a novel neuroprotective strategy for ALS treatment.",

Rosmarinic acid (RA), a polyphenolic compound with antioxidant and neuroprotective properties, has not yet been evaluated for mitigating ISO-induced toxicity. In this study, Wistar albino rat pups were exposed to ISO (1.5% in 30% oxygen/air, 3-h) on postnatal days (P)7\u202f+P9\u202f+\u202fP11, and the protective effects of intranasal RA (25\u202fmg/kg) pretreatment (1-h before anesthesia) were investigated for the first time. Control groups received either oxygen alone or RA before oxygen exposure. On P12, hippocampal tissue was examined for detecting acute neuronal apoptosis, oxidative stress, inflammation, and stress-related proteins using histopathology and immunoblotting. Cognitive performance was assessed using Morris Water Maze tests that evaluated spatial learning (P28-P32) and both short- and long-term memory (P33, P60, P90). Repeated ISO exposure impaired learning and memory, increased anxiety-like behaviors, and caused hippocampal damage, along with elevated pro-apoptotic markers (Bax/Bcl-2 ratio, cleaved caspase-3, PARP1 fragments), redox imbalance and inflammation (reduced SOD1; increased GPX1, 4HNE, NF-\u03baB-p65, TNF-\u03b1). ISO also disrupted stress signaling by reducing p-HSF1, Hsp90, and Hsp60 levels, while raising Hsp70 and decreasing 14-3-3 isoforms. RA pretreatment countered these effects by restoring antioxidant and stress-response proteins, reducing inflammation and apoptosis, and maintaining neuronal integrity and cognitive function. No harmful effects were observed in the RA-only group. These findings suggest that intranasal RA pretreatment may be a preventive strategy against anesthesia-related neurotoxicity in pediatric patients.",

Bax inhibitor 1 (BI1), an endoplasmic reticulum protein downregulated in ALS neuroprotective, represents a therapeutic target, but its metabolic regulatory mechanisms are incompletely understood. Using transcriptomics in skeletal muscle of ALS mice pre- and post-BI1 treatment, we identified BI1-regulated pathways. Structure-based virtual screening of FDA-approved compounds nominated lisinopril as a BI1 activator. Lisinopril upregulated BI1 protein expression, stabilizing mitochondrial membrane potential and protecting against SOD1G93A-induced apoptosis in NSC34 cells. Concurrently, it regulated TGF-\u03b21/mTOR-dependent autophagy, maintained NMJ integrity, and reshaped triglyceride/sphingolipid/glycerophospholipid metabolism to attenuate spinal cord pathology in ALS mice, promoting energy metabolism shift toward glucose oxidation. Additionally, lisinopril inhibited the TGF-\u03b21/Smad2/3 pathway to alleviate muscle fibrosis, downregulate Acp5/FN expression, and reduce type I collagen deposition. In conclusion, this study provides evidence that pharmacological activation of BI1 by lisinopril suppresses TGF-\u03b21, modulates lipid metabolism, and ameliorates ALS pathology, demonstrating promising therapeutic repurposing potential.",

Eugenol (EU), a natural antioxidant found in cloves, has demonstrated protective effects against different toxic substances. This experimental study explored whether eugenol could mitigate neurological damage triggered by glyphosate exposure in rats. A total of forty male Sprague-Dawley rats were allocated into five experimental groups consisting of control, eugenol (100\u202fmg/kg), glyphosate (150\u202fmg/kg), EU50 combined with glyphosate (50\u202fmg/kg + 150\u202fmg/kg), and EU100 combined with glyphosate (100\u202fmg/kg + 150\u202fmg/kg). Animals received the respective treatments by oral gavage for a period of seven days. Motor and anxiety-related behaviors were evaluated using behaviour tests, after which brain tissues were processed for histopathological analysis. Biochemical analyses included ELISA assessment of oxidative stress markers (MDA, SOD1, GSH, and GPx1), RT-PCR analysis of endoplasmic reticulum (ER) stress- and apoptosis-related genes (GRP78, ATF4, CHOP, PI3K/AKT/mTOR, BAX, and Bcl-2), Western blot evaluation of inflammatory and antioxidant signaling pathways (TLR4/NF-\u03baB and Nrf2/HO-1/SIRT1), and immunohistochemical and immunofluorescence analyses of neuroplasticity, circadian rhythm, and autophagy markers (BDNF, BMAL1, CLOCK, Beclin-1, and LC3A/B). GLY exposure significantly increased lipid peroxidation (MDA), ER stress markers (GRP78 and CHOP), pro-inflammatory mediators (TLR4, NF-\u03baB, TNF-\u03b1, and IL-1\u03b2), apoptotic signaling (BAX and caspase-3), and autophagy-related proteins, while suppressing antioxidant pathway components. Glyphosate exposure induced behavioral impairments accompanied by increased oxidative stress, inflammatory activation, endoplasmic reticulum stress, apoptosis, and dysregulated autophagy in cerebral cortex tissue. EU treatment dose-dependently attenuated these molecular and histopathological alterations, restored antioxidant and cellular stress responses, and significantly improved behavioral performance, indicating a protective role against GLY-induced neurotoxicity. Overall, EU may represent a promising therapeutic candidate for mitigating herbicide-induced brain injury.",

C57BL/6 mice were randomly divided into control (PBS), MNU-induced RP, and MNU+EGCG pretreatment groups. EGCG (50 mg/kg, intraperitoneal) was administered daily for 3 consecutive days prior to a single MNU injection (50 mg/kg). Retinal function was evaluated by scotopic electroretinography (ERG). Retinal structure was assessed using optical coherence tomography (OCT) and hematoxylin-eosin staining, with outer nuclear layer (ONL) thickness measurement. Mechanisms were explored via RNA sequencing, reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) validation of oxidative stress- and inflammation-related genes, and immunohistochemistry for microglial activation, astrocytic gliosis, and apoptosis markers. Compared with the MNU group, EGCG pretreatment significantly preserved scotopic ERG a-wave and b-wave amplitudes (P<0.001). OCT and histological analysis showed that EGCG markedly attenuated MNU-induced thinning of total retina and ONL (P<0.005, P<0.001, respectively). RNA sequencing identified 1147 differentially expressed genes modulated by EGCG, with significant upregulation of antioxidant genes (Nrf2, Sod1, Gpx4, Cat1, Ho-1) and downregulation of pro-inflammatory genes. Immunohistochemistry confirmed that EGCG significantly reduced microglial activation, glial fibrillary acidic protein (GFAP) expression, and cleaved caspase-3-positive cells (P<0.01 to P<0.001). EGCG exerts robust neuroprotective effects in MNU-induced RP through enhancement of antioxidant defenses, suppression of neuroinflammation, and preservation of retinal structure and function. These findings suggest EGCG as a promising candidate for adjuvant antioxidant therapy in RP.",

Docosahexaenoic acid (DHA) exhibits neuroprotective effects, but its limited transport across the blood-brain barrier (BBB) restricts clinical utility. Major facilitator superfamily domain-containing protein 2A (MFSD2A) is the primary transporter of DHA into the central nervous system, yet its role in ALS remains unclear. This study investigated the therapeutic potential and mechanisms of MFSD2A overexpression combined with DHA supplementation in male SOD1^G93A ALS mice. We found that MFSD2A expression was markedly reduced in ALS mice and correlated with impaired motor function and neuronal damage. DHA supplementation or MFSD2A overexpression partially improved behavioral deficits, while their combination produced synergistic benefits. Histological analyses revealed attenuated neuronal degeneration and reduced muscle fibrosis following combined treatment. Furthermore, MFSD2A physically interacted with the E3 ubiquitin ligase TRIM21, regulating glycolytic metabolism by modulating key enzymes (GLUT1, HK2, LDHA, PDK1) and products (lactate/pyruvate and NADH/NADPH ratio). TRIM21 knockdown reversed MFSD2A-mediated neuroprotection and impaired glycolytic metabolism, indicating its critical role in this pathway. The combined intervention also suppressed systemic inflammation and oxidative stress by decreasing pro-inflammatory cytokines (TNF-\u03b1, IL-6, IL-1\u03b2) and restoring antioxidant enzyme activities (GSH-Px), while reducing lipid peroxidation (MDA). These findings suggest that MFSD2A facilitates DHA's neuroprotective effects by enhancing glycolytic metabolism and mitigating neuroinflammation. This study highlights MFSD2A and DHA as promising therapeutic targets in ALS and provides novel insights into overcoming BBB transport limitations for neurodegenerative disease treatment.",

Current therapeutic options provide only modest benefit, and the etiology of ALS remains incompletely understood. Emerging evidence implicates cellular senescence in the central nervous system (CNS) of ALS pathogenesis, with senescent astrocytes identified in both animal models and patients. We employed transgenic mice overexpressing the human superoxide dismutase 1 gene with a glycine-to-alanine substitution at codon 93 (hSOD1G93A) as the experimental model. To eliminate senescent cells, mouse-derived natural killer group 2, member D (NKG2D) chimeric antigen receptor T (CAR-T) cells were engineered to target NKG2D ligands (NKG2DLs) + senescent cells. The efficacy of senescent cell clearance was assessed by SA-\u03b2-gal staining on frozen tissue sections and by quantifying the expression of senescence-associated markers (e.g., p16INK4a, p21). Disease progression in mice was evaluated by monitoring changes in body weight, behavioral performance, and motor function. We found that NKG2DLs+ senescent cells accumulate in symptomatic transgenic mice. NKG2D CAR-T cells can selectively eliminate senescent cell populations in symptomatic hSOD1G93A mice. A single infusion effectively reduced senescent cell burden and suppressed Senescence-Associated Secretory Phenotype (SASP) features within central nervous system tissues. However, no significant improvements in motor function or survival were observed. These results indicate that while senescence is a pathogenic feature of ALS, it operates within an integrated disease network. Early senolytic intervention or combinatorial approaches may represent promising future strategies for ALS.",

Among these, methotrexate (MTX) is a widely used anticancer drug which exhibits certain limitations related to biocompatibility and solubility. Therefore, to address these limitations, MTX was covalently conjugated to multi-walled carbon nanotubes (MWCNTs) to develop a stable and targeted nanotherapeutic system. MWCNTs were first subjected to purification followed by carboxylation which was validated through dispersion solubility test. MTX-MWCNT was then subjected to characterization to validate successful conjugation after which the cytotoxic potential of MTX-MWCNT was assessed by cell viability assay on MCF-7 (hormone-positive breast cancer), MDA-MB 231 (triple-negative breast cancer), and HeLa (cervical cancer) cells. The evaluation of safety profile and hemocompatibility was done using non-cancerous HEK 293T (human embryonic kidney) cells and in vitro hemolysis assay respectively. The cytotoxic potential of MTX-MWCNT was assessed through cell viability assay which demonstrated a dose-dependent reduction in cancer cell viability after treatment with MTX-MWCNTs with minimal toxicity toward normal cells and blood. The anti-angiogenic potential of MTX-MWCNT was also tested further through ex vivo chick chorioallantoic membrane (CAM) assay which revealed significant reduction in vessel branching. The cytotoxic activity of MTX-MWCNT was also confirmed by biochemical assays, including cell proliferation assay, glucose estimation assay, and total antioxidant status (TAS). Moreover, the cytotoxic potential of MTX-MWCNT was further assessed at the gene level through quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis which demonstrated upregulation of the pro-apoptotic BAX gene and downregulation of the anti-apoptotic BCL-2 gene. Furthermore, kit-based enzyme-linked immunosorbent assay (ELISA) quantification further confirmed increased BAX, decreased BCL-2, and reduced telomerase protein expression. Lastly, the alteration in nuclear morphology in all three cancer cells post treatment with MTX-MWCNTs was evaluated through 4',6-diamidino-2-phenylindole (DAPI) staining followed by fluorescence microscopy. Collectively, the obtained findings highlight that MTX-MWCNT efficiently induces apoptosis and inhibits angiogenesis while maintaining significant biosafety, establishing it as an emerging nanoscale platform for targeted cancer therapy.",

As of yet, no curable remedy has been revealed. Nebivolol is a third-generation \u03b2-blocker that has numerous cytoprotective properties and is used to treat heart failure and hypertension. Its potential ability to prevent bleomycin-induced IPF has not been studied. The aim of the current study is to investigate the antifibrotic effect of nebivolol against bleomycin-induced lung fibrosis. Twenty-four male Wistar rats were randomly divided into four groups (n\u2009=\u20096 per group): control, bleomycin, nebivolol, and nebivolol\u2009+\u2009bleomycin. Pulmonary fibrosis was induced by bleomycin administration, while nebivolol was given seven days prior to a single intratracheal injection of bleomycin, daily orally for 21\u2009days. At the end of the study, lung injury and fibrosis were evaluated using histopathological analysis, lung wet/dry ratio, bronchoalveolar lavage fluid protein content, oxidative stress markers, inflammatory cytokines, and fibrosis-related signaling. Nebivolol significantly decreased the histopathological injuries demonstrated through lung tissue sections stained by hematoxylin/eosin and silver. It considerably decreased the lung wet/dry ratio, as well as the total protein level in bronchoalveolar lavage fluid. Further, nebivolol restored superoxide dismutase activity and suppressed elevated malondialdehyde levels, rebalancing the disrupted oxidative indicators. Nebivolol is additionally known to have anti-inflammatory effects, as demonstrated by a decrease in cytokine levels, including tumor necrosis factor-alpha (TNF-\u03b1), interleukin-1 beta (IL-1\u03b2), and interleukin-6 (IL-6), while boosting the secretion of the anti-inflammatory mediator endothelial nitric oxide synthase. In addition, nebivolol's anti-inflammatory properties were obvious by its suppressing effect on Toll-like receptor 4 (TLR4) level and the matrix metalloproteinase-2 (MMP-2) expression. Finally, nebivolol mitigated the progression of the fibrotic cascade, as indicated by reducing the elevated levels of transforming growth factor beta (TGF-\u03b2) and heat shock protein 47 (HSP47). Nebivolol treatment exhibited remarkable protective effects on bleomycin-mediated IPF in rats via suppressing TLR4/IL-1\u03b2/MMP-2 and TGF-\u03b2/HSP47 signaling pathways. This study might provide an innovative therapeutic approach to prevent the devastating lung scarring associated with IPF.",

Experimental colitis was induced by the rectal administration of 2,4,6-Trinitrobenzenesulfonic acid (TNBS). Primary intestinal cells, luciferase reporter assay and nuclear factor erythroid 2-related factor 2(Nrf2)-null mice were used to clarify if Tan IIA ameliorates ferroptosis and oxidative injury in TNBS-induced colitis dependent on Nrf2. Tan IIA (20\u202fmg/kg) ameliorated colonic weight/length ratio, pathological scores and fibrosis in TNBS-induced mice. Moreover, Tan IIA reduced pro-inflammatory factors and increased the expression of tight junction proteins, likely contributing to the improvement of colonic barrier integrity. Tan IIA significantly induced the expression of Nrf2 target genes in primary intestinal epithelial cells and activated Nrf2 luciferase reporter activities in HCT116\u202fcells. In TNBS-induced wild-type mice but not in Nrf2-null mice, Tan IIA significantly improved ferroptosis and oxidative injury as revealed by decreased ferritin light chain (FTL) level and upregulated Nrf2 downstream genes heme oxygenase-1 (HO-1) and superoxide dismutase 1 (SOD1) expression. In conclusion, Tan IIA significantly alleviates colonic ferroptosis and oxidative injury induced by TNBS in mice through modulation of the Nrf2 signaling.",

In this study, the toxicity of 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) and 2-octyl-2H-isothiazol-3-one (OIT), tested individually and in combination, was investigated using the zebrafish (Danio rerio) fish embryo toxicity (FET) test coupled with targeted gene expression analysis. Acute toxicity was evaluated over 96\u2009h after fertilization, and median lethal concentrations (LC\u2085\u2080) were determined. DCOIT exhibited higher intrinsic toxicity (LC\u2085\u2080\u2009=\u20090.015\u2009mg/L) compared to OIT (LC\u2085\u2080\u2009=\u20090.14\u2009mg/L), while the mixture showed increased toxicity (LC\u2085\u2080\u2009=\u20090.006\u2009mg/L). Sublethal developmental effects included pericardial and yolk sac edema following DCOIT exposure and depigmentation in larvae exposed to higher concentrations of OIT. To gain insight into potential molecular responses, the expression of selected genes related to inflammation, oxidative stress, and apoptosis was assessed by qRT-PCR at sublethal concentrations. Exposure to both single compounds and their mixture resulted in the modulation of pro-inflammatory markers (tnf-\u03b1 and il-1\u03b2), antioxidant enzymes (sod-1 and cat), and apoptosis-related genes (casp3 and tp53), with generally stronger responses observed at higher concentrations and under mixture exposure. Overall, the results indicate that early life stages of zebrafish are sensitive to both DCOIT and OIT, and that combined exposure can enhance toxicity and molecular responses. Moreover, early developmental exposure to isothiazolinones is associated with the activation of inflammation-related molecular pathways, highlighting their potential risk for aquatic ecosystems.",

To address this multifactorial pathology, we developed an integrated nano-therapeutic platform, termed CMEPA, that unites three complementary components: a copper-based nanozyme with dual superoxide dismutase (SOD)- and catalase (CAT)-like activities, human umbilical cord mesenchymal stem cell-derived exosomes (UC-MSC-Exos) enriched in regulatory microRNAs, and a hepatocyte-targeting antibody against ASGR1. In vitro, CMEPA efficiently scavenged reactive oxygen species (ROS), significantly reduced lipid droplet accumulation, and suppressed apoptosis in palmitic acid-challenged hepatocytes. In vivo, CMEPA exhibited preferential hepatic accumulation and an excellent biosafety profile, with no observable systemic toxicity. Therapeutic evaluation in a diet-induced murine MASLD model revealed that CMEPA administration significantly improved serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride, and cholesterol levels, alleviated hepatic steatosis as confirmed by histopathology, enhanced endogenous SOD and CAT activities, and attenuated inflammatory and lipogenic signaling pathways, as revealed by transcriptomic analysis. Collectively, these results establish CMEPA as a robust, multi-modal nano-therapeutic strategy that integrates catalytic antioxidation, exosome-mediated gene regulation, and active hepatocyte targeting, offering a promising translational approach for MASLD treatment.",

To achieve selective radioprotection of normal tissues, we systematically evaluated, in\u00a0vitro and in\u00a0vivo, the antioxidant and radioprotective performance of a previously engineered fusion antioxidant enzyme, GS1XR (GST-SOD1-X-R9). GS1XR efficiently enters normal cells in low matrix metalloproteinases (MMP)-2/9 environments, scavenges radiation-induced reactive oxygen species (ROS), maintains the Nrf2 antioxidant pathway, suppresses apoptosis, and increases clonogenic survival. In contrast, in 3D tumor microenvironments with high MMP-2/9, cleavage of the X peptide removes R9, resulting in a loss of transmembrane capacity and a pronounced reduction in intracellular ROS scavenging. Animal studies further showed that GS1XR significantly alleviates whole-body irradiation-induced hematopoietic injury and, in tumor-bearing models receiving radiotherapy, does not compromise radiotherapy-mediated tumor control. Collectively, GS1XR couples microenvironment-responsive cell entry with enzymatic antioxidation to achieve selective radioprotection while preserving radiotherapy-mediated tumor control.",
"41981505": "ID: 41981505\nTitle: Alkaline sphingomyelinase (ENPP7) attenuates DSS-induced colitis by modulating FOXO1-mediated antioxidative stress responses.\nAbstract: BACKGROUND: Alkaline sphingomyelinase (alk-SMase), also known as ectonucleotide pyrophosphatase/phosphodiesterase 7 (ENPP7), is an intestinal enzyme involved in sphingolipid metabolism and has been implicated in the regulation of inflammation. However, its role in intestinal inflammation and the underlying mechanisms remain unclear. This study aimed to investigate the role of ENPP7 in dextran sulfate sodium (DSS)-induced colitis, with a particular focus on oxidative stress and FOXO1-related signaling pathways. METHODS: ENPP7 knockout (KO) and wild-type (WT) mice were used to establish a DSS-induced colitis model. Disease severity was assessed by body weight change, disease activity index (DAI), colon length, histopathological analysis, and plasma oxidative stress markers. Levels of pro-inflammatory cytokines and antioxidant enzymes were measured using standard biochemical assays. In vitro, polarized Caco-2 cells were subjected to ENPP7 knockdown and FOXO1 overexpression to evaluate their roles in antioxidative responses. RESULTS: ENPP7 deficiency significantly aggravated DSS-induced colitis, as evidenced by greater body weight loss, higher DAI scores, and shorter colon length. This effect was accompanied by reduced FOXO1 expression, and was associated with diminished antioxidant defense and mitochondrial dysfunction-related alterations. Additionally, KO mice showed increased levels of pro-inflammatory cytokines (IL-1\u03b2 and TNF-\u03b1) and decreased activities of antioxidant enzymes (CAT and SOD1) in intestinal mucosal tissues compared with WT mice. In Caco-2 cells, ENPP7 knockdown reduced FOXO1 expression, which was associated with impaired antioxidant capacity, whereas FOXO1 overexpression partially reversed these effects. CONCLUSIONS: ENPP7 attenuates DSS-induced colitis, at least in part, by modulating FOXO1-mediated antioxidant responses, thereby influencing oxidative stress and inflammatory processes. These findings highlight ENPP7 as a potential therapeutic target for ulcerative colitis, although further mechanistic and clinical studies are warranted.",

Peripheral blood samples were collected from ALS patients and healthy controls (HC) to establish the iPSC-derived motor neurons (MNs). Whole-cell patch-clamp recordings at different culture stages was made using an Axopatch 700B amplifier in combination with pClamp 11 software (Molecular Devices). The frequency of action potentials (APs) was recorded. Additionally, Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) Nick-End Labeling (TUNEL) was used to assess the apoptosis of MNs. ALS patient-derived MNs exhibited significantly higher firing rates compared to HCs at both 4-7 weeks (p = 0.004) and 7-9 weeks (p = 0.009). Further analysis revealed that SOD1-derived MNs showed significantly higher firing frequencies than sALS (p = 0.009) and HCs (p < 0.001) in 4-7 weeks. In 7-9 weeks, it remained significant between SOD1 and HC-derived MNs (p = 0.015), but became insignificant between SOD1 and sALS (p = 0.855). The apoptotic rate of sALS (Day 30: 61.37% \u00b1 9.63%; Day 60: 78.41% \u00b1 6.63%) and SOD1 (Day 30: 73.69% \u00b1 8.81%; Day 60: 60.37% \u00b1 11.53%) -derived MNs was significantly higher than those of HCs at both Day 30 (30.72% \u00b1 7.57%) and Day 60 (50.85% \u00b1 19.36%) (p < 0.001). MNs derived from both patients with mutant SOD1 and sporadic ALS exhibited increased excitability compared to HCs. The increased excitability of MNs derived from ALS patients with mutant SOD1 occurred earlier, and over time, became consistent with the excitability observed in MNs derived from sporadic ALS. The apoptosis rates of MNs showed similar trends. iPSC-derived MNs from both sporadic and mutant ALS may serve as useful cell models for ALS in future studies.",

Gymnocypris eckloni, a representative species of the Qinghai-Tibetan Plateau, exhibits excellent adaptability to hypoxic environments, however, little is known about the hypoxic adaptation mechanisms of G. eckloni. Herein, effects of acute hypoxia for 12\u00a0h (H12S) and chronic hypoxia for different durations (H24S, H96S and H168S) on biochemical parameters and transcriptome of G. eckloni gills were investigated. We found that the gills suffered severe oxidative damage and increased anaerobic glycolysis was observed across all groups, and aerobic glycolysis was elevated in H12S. Inflammatory response, apoptosis and translation process were markedly suppressed, and signal transmission and protein synthesis process were strengthened under acute hypoxia stress. Through STEM and WGCNA, we identified several key hub genes (egln, akt, pdk1, foxo1, pfk, gapdh, gk, bax, casp8, il-8 and il-1\u03b2) related to hypoxia from 3608 DEGs, and expression of akt, gk, sdh, gapdh and ldh was significantly upregulated under hypoxia stress, and sod1, cat, bax, casp8 and ccl8 showed an opposite trend. Enrichment analysis revealed that most DEGs were significantly enriched in MAPK signaling pathway, cytokine-cytokine receptor interaction, FoxO signaling pathway, mTOR signaling pathway, glycolysis/gluconeogenesis and apoptosis. The study revealed the differences in the molecular mechanisms of G. eckloni in responding to acute and chronic hypoxia stress, and provided valuable genetic resources for breeding hypoxic-tolerant fish.",
"41996987": "ID: 41996987\nTitle: Decoding RNA splicing pathology: Alternative splicing in amyotrophic lateral sclerosis and its therapeutic potential.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive motor neuron loss, leading to muscle weakness, paralysis, and respiratory failure. Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival.",
"41997149": "ID: 41997149\nTitle: SARM1 executes neuronal parthanatos and promotes excitotoxic cell death.\nAbstract: The nicotinamide adenine dinucleotide (NAD+) hydrolase sterile alpha and Toll/interleukin-1 receptor motif-containing 1 (SARM1) is the central executioner of pathological axon degeneration and is allosterically activated by an increased nicotinamide mononucleotide (NMN)/NAD+ ratio. DNA damage induces NAD+ loss and an increased NMN/NAD+ ratio by hyperactivating poly(ADP-ribose) polymerase 1 (PARP1), which triggers the parthanatos cell death pathway. Multiple mechanistically distinct DNA-damaging agents activate SARM1 and induce axon degeneration following PARP1 activation. Remarkably, SARM1 is required for key steps downstream of hyperactivated PARP1, which are pathognomonic of parthanatos, including mitochondrial depolarization, nuclear translocation of apoptosis-inducing factor (AIF), and cell death. Hence, SARM1 is an essential component of neuronal parthanatos. Moreover, complex neurodegenerative stimuli whose mechanisms include activation of parthanatos, such as 1-methyl-4-phenyl-pyridinium (MPP+) dopaminergic neuron toxicity and N-methyl-D-aspartate (NMDA) excitotoxicity, are potently protected by SARM1 inhibition. These findings place SARM1 at the nexus of multiple mechanisms driving neuronal cell death, thereby greatly expanding the potential clinical utility of SARM1 inhibitors beyond diseases of axon loss.",

This study investigated the effects of a Chinese Herbal Mixture Extract (CHE) comprising honeysuckle, astragalus, M. officinalis and tangerine peel as a dietary supplement in weaned lambs. Forty-eight 60-day-old lambs were randomly assigned to four groups: control (CON, basal diet), and basal diet supplemented with 0.1% (LCHE), 0.2% (MCHE), or 0.4% CHE (HCHE) for 56 days. Growth performance, immunity, antioxidant status, biochemical parameters, organ histology and rumen microbiota were evaluated. Data were analyzed by one-way ANOVA. Compared with CON, MCHE and HCHE significantly increased average daily gain (ADG) and decreased the feed-to-gain ratio (F/G) (P\u202f<\u202f0.05). In addition, apparent digestibility of crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) was improved (P\u202f<\u202f0.05). These groups showed growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels (P\u202f<\u202f0.05), increased immunoglobulin (IgA, IgG) concentrations and superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) activities (P\u202f<\u202f0.05), and reduced malondialdehyde (MDA) (P\u202f<\u202f0.05). The HCHE increased serum total protein (TP) and calcium (Ca) at day 56 (P\u202f<\u202f0.05). Dietary CHE supplementation (0.1% - 0.4%) increased the villus height-to-crypt depth ratio (P\u202f<\u202f0.05), with no significant pathological lesions observed in major organs upon histological examination. Microbiota analysis showed that CHE reshaped rumen microbiota, increased the relative abundance of Euryarchaeota (P\u202f<\u202f0.05), which have a positive effect on enhancing carbohydrate and lipid metabolic pathways based on inferred functional potential.

In this experimental study, a total of 49 rats were randomly divided into seven groups, receiving MTX (20 mg/kg) alone and in conjunction with different doses of Daucus carota extract (200 and 400 mg/kg), Piper nigrum extract (15 and 7.5 mg/kg), a combination of Pipe nigrum at 7.5 mg/kg, and Daucus carota at 200 mg/kg, and a control group. The extracts were given orally through gavage starting one day before MTX treatment and continuing for two weeks. The study measured blood testosterone levels, Johnson's index, and seminiferous tubule diameter from tissue sections. It also assessed markers of oxidative stress [reactive oxygen species (ROS), Nitrite, malondialdehyde (MDA), glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), as well as levels of myeloperoxidase (MPO), mitochondrial membrane potential (MMP), and the consistency of testicular tissue. The MTX-exposed group exhibited remarkable testicular tissue damage, as indicated by increased ROS, MDA, and Nitrite levels compared to the control group. Moreover, there were notable reductions in CAT, GSH, SOD, testosterone levels, Johnson index, and seminiferous tubule diameter in the MTX-treated rats. However, treatment with Pipe nigrum and the combination of Pipe nigrum with Daucus carota extracts significantly reduced testicular damage and reduced oxidative stress markers compared to the MTX group. The study suggests that alcoholic extracts of Daucus carota and Pipe nigrum may help alleviate the harmful effects of MTX on testicular tissue, potentially offering a therapeutic option for male infertility due to chemotherapyrelated testicular damage.",
"42003614": "ID: 42003614\nTitle: Vacuolar iron export alters the synergy between doxycycline and fluconazole by affecting cidal ROS levels in Candida albicans.\nAbstract: Fungal infections are combatted using three main classes of antifungals, of which the azoles, considered to be fungistatic, are the most widely used. Slow growth of Candida albicans at supra-minimal inhibitory concentrations (MIC) of fluconazole (FLC), termed tolerance, is routinely observed. A combination therapy resulting in the eradication of this fungistatic character would be a valid therapeutic strategy, and indeed, the synergistic combination of the antibiotic doxycycline and FLC has such an effect. We hypothesized that iron-requiring mitochondrial functions may be the targets of the synergistic combination. The proteome enriched for mitochondria obtained from FLC + Fe-treated cells hinted that iron alleviated the FLC stress and that intracellular iron homeostasis, more specifically the vacuolar iron exporter Smf3, might be a key factor during FLC treatment, as its expression was induced. Moreover, a ROS assay revealed that a smf3\u0394/\u0394 strain treated with FLC accumulated ROS to a similar extent as that displayed by the WT undergoing a FLC+DOX combination treatment. Thus, deletion of SMF3 mimics the addition of doxycycline in wild-type cells. The ROS accumulation can be attenuated through overexpression of the mitochondrial superoxide dismutase SOD2, and this restored the synergy between DOX and FLC in the smf3\u0394/\u0394 background. ROS accumulation, in part through altered iron availability from the vacuolar storage pool, is thus the molecular mechanism underlying the synergy between doxycycline and FLC. Furthermore, no effect on either cidality or tolerance was observed in the smf3\u0394/\u0394 strain, highlighting that synergy is not necessarily an indication of cidal therapies.IMPORTANCEAzoles are widely used against Candida albicans, yet many cells survive above the minimal inhibitory concentrations (MIC) by growing slowly, which can prolong infection and foster resistance. We show that intracellular iron homeostasis alters the fluconazole characteristics by affecting ROS accumulation in mitochondria, and that this is the molecular mechanism underlying the combination therapy of fluconazole and doxycycline. These results place iron release from the vacuole at the center of azole responses, suggesting novel ways to boost azole efficacy.",

Forty-eight rats were divided into eight groups (n\u202f=\u202f6). Group A received distilled water, and Group B received doxorubicin (10\u202fmg/kg). Groups C and D received SRF (50 or 100\u202fmg/kg) for 14 days. Groups E and F received doxorubicin with SRF, while Groups G and H were pretreated with SRF before doxorubicin on day 15. Blood and heart tissues were collected for analysis after euthanasia. Rats in the doxorubicin-only group (Group B) exhibited significant elevations in serum cardiac injury markers, including lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB), along with increased systolic and diastolic blood pressures and elevated malondialdehyde (MDA) levels. Conversely, activities of key antioxidant enzymes-superoxide dismutase (SOD) and catalase (CAT)-were markedly reduced. Enhanced glycogen accumulation, Caspase-3 activation, and CD4 expression further indicated heightened oxidative stress and apoptosis. Treatment with SRF, particularly in the pre- and co-administration protocols, significantly attenuated these alterations.

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.",

Betacyanins, betalain pigments found in red dragon fruit and beetroot, display powerful anti-inflammatory and free-radical scavenging properties which may help ameliorate ALS pathology and slow disease progression. The present study characterized the therapeutic effects of a betacyanin-rich red dragon fruit extract (DFE) in the G93A mutant hSOD1 transgenic mouse model of ALS. Mice were treated orally with 5% (v/v) DFE in drinking water ad libitum, from disease onset until end-stage. DFE treatment had a statistically significant effect on survival, with an approximate 13-day extension of median lifespan in the treated G93A mutant hSOD1 group. Treatment with DFE also significantly preserved muscle strength and endurance, as assessed by grip strength and rotarod behavioral testing. This was associated with a modest but statistically significant preservation of gastrocnemius muscle weight in the DFE-treated group. Histopathological analyses demonstrated improvements in NMJ size and complexity, an increase in surviving spinal cord motor neurons, and a reduction in spinal cord astrogliosis in G93A mutant hSOD1 mice treated with DFE, when compared to their untreated mutant littermates. Overall, these findings indicate that DFE, or purified betacyanin compounds, should be investigated further as potential therapeutic agents for patients with SOD1-related ALS. Additional preclinical studies in non-SOD1 models of ALS will need to be completed to determine the potential benefit of betacyanin compounds in sporadic ALS.",

This research is designed to determine the impact of PSO on damage to the hippocampus, bone, and bone marrow in rats triggered by lead acetate. Thirty-two adult male rats were subjected to this study. The animals were divided into four groups at random after they had acclimated. The control group received 1 ml/kg of normal saline for 21 days. Animals in the Pb group received 500 ppm of lead acetate in drinking water for 21 days. Pb+ PSO 0.4 ml/kg and Pb+ PSO 0.8 ml/kg received 0.4 or 0.8 ml/kg of PSO intraperitoneally, concomitant with exposure to lead acetate for 21 days. Blood, bone, bone marrow, and hippocampus samples were taken after the treatment for measuring malondialdehyde (MDA), thiol content and superoxide dismutase (SOD). Our results revealed that 0.8 ml/kg of PSO significantly decreased malondialdehyde in bone marrow, serum, and hippocampus. It also could increase thiol in serum and superoxide dismutase in bone marrow. PSO could protect against lead-induced damage in bone, bone marrow, and hippocampus of treated animals through reduction of oxidative stress.",

Neurodegenerative diseases (NDs), including Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis, are characterized by oxidative stress, mitochondrial dysfunction, metabolic impairment, protein aggregation, and cytoskeletal instability-features that may provide a permissive intracellular context for disulfidptosis. However, its occurrence and pathological relevance in these disorders remain incompletely understood. In this review, we examine the potential involvement of disulfidptosis in neurodegenerative diseases from a disease-centered perspective. We emphasize that current evidence is largely indirect and based on mechanistic overlap rather than direct experimental validation in neural systems. Accordingly, we distinguish between direct evidence, indirect mechanistic support, and pathophysiological plausibility. We further discuss cell-type-specific susceptibility across neurons and glial cells, analyze its relationship with other cell death pathways, and consider potential therapeutic implications. Overall, disulfidptosis is best regarded as a context-dependent and emerging mechanism that may contribute to neuronal vulnerability under specific metabolic and redox constraints. Clarifying its disease relevance will be essential for determining its significance in neurodegeneration and its potential as a therapeutic target.",

To address this, we conducted a systematic review and meta-analysis of spinal muscular atrophy (SMA) mouse studies, revealing 60% variability in reported MN loss, largely attributable to nonspecific spinal cord sampling. Using a whole-segment approach with tissue clearing, MN tracing, and multimodal imaging, we confirmed segment-dependent differences in MN counts. Common MN markers (SMI-32, Nissl) lacked specificity, whereas choline acetyltransferase (ChAT) provided robust labeling in murine and human spinal cords. Deep learning-based whole-mount segmentation enabled unbiased MN quantification and validated manual counts. Integrating analysis with computational modeling established segment sampling as a key driver of variability and revealed degeneration patterns: widespread MN loss in amyotrophic lateral sclerosis (ALS), selective MN loss in severe SMA, and preservation in mild SMA models. These findings establish a framework for reproducible MN quantification.",

This study evaluated the neuroprotective potential of caffeic acid phenethyl ester (CAPE) against MTME\u2009+\u20095-induced neurotoxicity in an ALS-like pathology model. CAPE (50 and 100\u00a0mg/kg., p.o.) demonstrated significant therapeutic efficacy by improving motor and cognitive deficits, restoring oxidative balance, and mitigating neuroinflammatory and apoptotic pathways. Behavioral assessments, including the open field, grip strength, forced swim, and Morris water maze, highlighted CAPE's ability to restore neuromuscular coordination and cognitive function in a dose-dependent manner. Cellular and Molecular analyses revealed that MTME+5 exposure significantly disrupted Klotho/SIRT-1/Nrf2/HO-1 antioxidant signaling, increased pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and elevated apoptotic markers (Bax, caspase-3) while depleting anti-inflammatory cytokines (IL-10) and neuroprotective proteins. Furthermore, CAPE treatment restored these parameters, reduced oxidative stress, and enhanced antioxidant defenses (SOD, CAT, r-GSH). Furthermore, CAPE normalized neurotransmitter imbalances, including acetylcholine, dopamine, GABA, serotonin, and glutamate, alleviating excitotoxicity. Histopathological and gross morphological analyses confirmed CAPE50 and CAPE100 ability to preserve neuronal and myelin integrity across key brain regions, including the cerebral cortex, hippocampus, striatum, midbrain, and cerebellum. CAPE also reduced methylmercury accumulation in the brain and cerebrospinal fluid, indicating detoxifying effects. Co-administration of vitamin B1 (VTB1(200)) further amplified CAPE's therapeutic efficacy. Complete blood count (CBC) analysis demonstrated MTME+5-induced hematological abnormalities, including reduced RBCs, hemoglobin, WBCs, and platelets, alongside elevated eosinophils and basophils. CAPE treatment normalized these parameters, indicating systemic recovery. These findings establish CAPE as a promising neuroprotective agent for ALS, capable of targeting neurocomplications.",

Phosphorus (32P)-labeled cDNA from AAA specimens (mean AAA size 6.65 cm) and normal aortas were hybridized with a 588-gene microarray primarily of the cardiovascular system. The results were validated by qRT-PCR. A total of 35 out of the 588 genes were differentially expressed, with either log2 ratio of AAAs/controls \u22651 (upregulated; 20 genes) or \u2264-1 (downregulated; 15 genes) in AAA lesions vs. normal aorta, and 25 of these were significantly different (71%).

"42054746": "ID: 42054746\nTitle: From necroptosis to neuroinflammation: Unraveling mechanisms and therapeutic targets in age-related cognitive decline.\nAbstract: Aging is the major risk factor for several chronic conditions, including cognitive decline and dementia. It is accompanied by profound immune alterations characterized by a progressive decline in immune competence, a process known as immunosenescence. The resulting dysregulation of immune function leads to the overproduction of proinflammatory cytokines and fuels a persistent, low-grade inflammatory state termed inflammaging. This chronic inflammation contributes to dysfunction across the central and peripheral nervous systems, promoting neuronal damage and accelerating neurodegenerative processes such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and other age-related cognitive disorders. Within this framework, prolonged activation of inflammatory pathways can trigger regulated forms of cell death. Among these, necroptosis has recently emerged as a potential mediator linking inflammaging to neurodegeneration. Its core molecular effectors, including the receptor-interacting protein kinases RIPK1 and RIPK3 and the mixed-lineage kinase domain-like protein (MLKL), are increasingly expressed in aged neural tissues, promoting the release of damage-associated molecular patterns (DAMPs) that amplify glial activation, oxidative stress, and blood-brain barrier disruption. Growing evidence suggests that necroptotic signaling may be upregulated in the aging brain and in neurodegenerative disorders, where it could contribute to neuronal loss and cognitive impairment. This review discusses the potential role of necroptosis in the continuum between inflammation and neurodegeneration, highlighting emerging diagnostic and therapeutic perspectives. Epigenetic and circulating biomarkers, such as phosphorylated MLKL and specific microRNAs, may support early detection, while pharmacological and nutraceutical strategies targeting necroptosis show promising neuroprotective effects in preclinical studies.",

Traditionally approved for osteoporosis and breast cancer prevention, its tissue-selective estrogen receptor modulation underpins its potential therapeutic applications. This review critically examines the pharmacological, preclinical, and clinical evidence supporting raloxifene's neuroprotective and neuropsychiatric effects, as well as its mechanisms of action, safety profile, and clinical limitations. Raloxifene exerts neuroprotective effects by targeting estrogen receptors, including ER\u03b1, ER\u03b2, and GPER, modulating genomic and non-genomic pathways. These pathways regulate oxidative stress, mitochondrial stability, neuroinflammation, and apoptosis-core features of neurological disorders such as Alzheimer's (AD), Parkinson's (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS). Preclinical studies demonstrate raloxifene's ability to reduce amyloid-\u03b2 aggregation in AD, protect dopaminergic neurons in PD, mitigate demyelination in MS, and decrease protein aggregation in ALS. Additionally, raloxifene exhibits positive effects on memory, attention, and negative symptoms in schizophrenia, alongside antidepressant and anxiolytic properties. Although promising, raloxifene's clinical translation faces challenges. Existing trials are limited by small sample sizes, heterogeneous designs, and a lack of long-term data. Most studies focus on postmenopausal women, leaving gaps regarding effects in men, premenopausal women, and younger populations. Furthermore, discrepancies between preclinical and clinical dosing complicate its therapeutic optimization. Future research should explore sex-specific effects, optimize CNS-targeted dosing strategies, and employ biomarkers for neuroprotection and inflammation. Long-term trials are essential to evaluate its disease-modifying potential. Raloxifene represents a promising repurposing candidate for CNS disorders, however, its therapeutic role remains to be established through robust clinical validation.",

Despite the widespread impact, there are currently no viable pharmaceuticals to treat these disorders. The mTOR protein is a crucial regulator of cell survival, growth, autophagy, and apoptosis.

"42062868": "ID: 42062868\nTitle: IRE1-XBP1driven induction of TMED9 stabilizes ATF6 during ER stress to promote cell survival.\nAbstract: The endoplasmic reticulum (ER) plays a central role in protein homeostasis by facilitating the folding, modification, and quality control of secretory and membrane proteins. Disruption of ER function results in protein misfolding and ER stress, which activate the unfolded protein response (UPR). While the three canonical UPR branches, inositol-requiring enzyme 1 (IRE1), protein kinase RNA-like endoplasmic reticulum kinase (PERK), and activating transcription factor 6 (ATF6), have been extensively studied, the mechanisms that coordinate their activities and ultimately dictate survival or death remain poorly understood. Transmembrane P24 trafficking protein 9 (TMED9), a cargo receptor that cycles between the ER and Golgi, has been implicated in protein quality control under pathological conditions, but its physiological role in ER proteostasis and UPR signaling is unclear. The ER stress response was studied in cellular human models including normal epithelial cells and patient-derived pediatric glioma cultures. To define the regulatory mechanisms dictating TMED9 expression, quantitative Reverse Transcription polymerase chain reaction (qRT-PCR), luciferase reporter assay, and western blotting were employed. To elucidate TMED9 function, loss-of-function approaches, including clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9-mediated knockout and small interfering RNA knockdown were used in combination with RNA-seq and live imaging. Protein stability was tested by pulse-chase experiments, ubiquitination, and degradation analyses. To study the implications of TMED9 activation, we screened curated gene expression datasets from the European Molecular Biology Laboratory- European Bioinformatics Institute (EMBL-EBI) Expression Atlas and employed live-cell imaging-based assays and functional assays (cell viability, apoptosis, migration, and self-renewal). Our study uncovers a physiological role for TMED9 in ER proteostasis and UPR signaling. We show that, under ER stress, TMED9 expression is transcriptionally induced by the IRE1-spliced X-box binding protein 1 (XBP1s) pathway via a conserved unfolded protein response element (UPRE)-like element in its promoter. Removal of TMED9 selectively impairs ATF6 activation without altering IRE1 or PERK signaling, resulting in increased sensitivity to ER stress-induced apoptosis. Mechanistically, we identify TMED9 as a stress-induced stabilizer of ATF6 that prevents its ubiquitin-dependent proteasomal degradation. Functionally, TMED9 regulation is exploited by tumor cells, which sustain IRE1-XBP1s activity to upregulate TMED9, thereby enhancing survival under ER stress conditions. Collectively, our findings establish TMED9 as a critical regulator of ER stress adaptation. TMED9 emerges as a molecular mediator that links IRE1-dependent transcriptional response to ATF6 stabilization, ultimately supporting increased secretory demand under stress conditions and in cancer development.",

The variability in disease progression underscores the necessity for tailored diagnostic and therapeutic approaches. MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression, have emerged as promising biomarkers and therapeutic targets in ALS. Dysregulation of specific miRNAs has been linked to mechanisms of ALS, including neuromuscular dysfunction, neuroinflammation, and neuronal survival/apoptosis. The potential of miRNA-based therapies, such as mimics and inhibitors, offers a more integrated approach by modulating entire disease networks, rather than targeting isolated pathways. However, challenges persist, particularly in delivering these therapies efficiently across the blood-brain barrier and minimizing off-target effects. Current delivery strategies involving nanoparticles, viral vectors, and exosome-based approaches require optimization for clinical use. This review synthesizes the latest research on miRNA-mediated mechanisms in ALS, evaluating their diagnostic, prognostic, and therapeutic potential, while highlighting the current limitations in clinical validation. It underscores the importance of standardized methodologies, multi-omics integration, and rigorous validation to facilitate the clinical translation of miRNA-based strategies. Standardized protocols and multicenter validation in large cohorts are essential to confirm the diagnostic accuracy of miRNAs, paving the way for their clinical application in ALS precision medicine.",

Gene expression analysis of the spinal cord and gastrocnemius of the SOD1-G93A ALS mouse model revealed a strong increase in inflammatory pathways and, specifically in the ALS gastrocnemius, a decrease in mitochondrial transcription and an increase in ribosomal protein expression. Treatment of ALS mice with the polyamine spermidine (SPD), a promising molecule in combating neurodegeneration and muscle atrophy, is able to partially restore the expression of more than four thousand genes in gastrocnemius tissue, including the mitochondrial regulator Pgc1\u03b1, as well as all the mitochondrial encoded genes and a large class of ribosomal proteins. SPD enhanced mitochondrial bioenergetics, as evidenced by Seahorse experiments, and delayed muscle weakness in vivo, as shown by grip strength records. These findings suggest that SPD can act as a potential supplement in the therapeutic strategy for ALS, offering a foundation for further research to improve patient outcomes.",
"42073997": "ID: 42073997\nTitle: Impact of Oxidative Stress-Driven Ferroptosis in Neurodegeneration.\nAbstract: Ferroptosis is an iron-dependent cell death driven by lipid peroxidation and failure of cellular antioxidant defenses. It is triggered by oxidative stress and can be aggravated by aging, inflammation, and dysregulation of iron homeostasis. In the central nervous system, iron dyshomeostasis, mitochondrial dysfunction, and membrane lipid remodeling can amplify oxidative injury and increase susceptibility to ferroptotic damage, particularly in vulnerable neurons. There is growing evidence that ferroptosis-related processes are linked to Alzheimer's disease, Parkinson's disease, Huntington's disease, and Amyotrophic Lateral Sclerosis. This review addresses novel approaches to track ferroptosis in vivo, such as imaging and biomarker techniques, and important molecular mechanisms linking iron metabolism, reactive oxygen species, and PUFA-driven lipid peroxidation to neuronal damage. We also explore upstream transcriptional control via NRF2, iron chelation and iron-handling modulation, inhibition of lipid peroxidation, and reinforcement of the System Xc-GSH-GPX4 and CoQ10-linked defense pathways. Subsequently, we highlight translational issues that need attention to further progress ferroptosis-targeted therapies for neurodegenerative disease.",
"42074133": "ID: 42074133\nTitle: Pridopidine Protects ALS Patient-Derived Neural Progenitor Cells via Sigma-1 Receptor Activation.\nAbstract: The sigma-1 receptor (S1R) is an endoplasmic reticulum (ER)-resident protein enriched at the mitochondria-associated ER membranes (MAMs) that supports ER homeostasis, preserves mitochondrial function, and enhances cell survival under stress. Disruptions of MAM integrity and prolonged ER stress are well-recognized pathological features of amyotrophic lateral sclerosis (ALS), contributing to motor neuron dysfunction and degeneration. In this study, we evaluated the protective effects of pridopidine, a highly selective and potent S1R agonist currently in clinical development for Huntington's disease (HD) and ALS, using neural progenitor cells (NPCs) derived from induced pluripotent stem cells (iPSCs) from a patient with sporadic ALS. Exposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted mitochondrial membrane potential, upregulated expression of the mitochondrial apoptotic marker, BAX, increased caspase-3 activation, and reduced cell viability. Pridopidine significantly attenuated tunicamycin-induced BiP and CHOP expression in a biphasic, dose-dependent manner (with maximal efficacy at 1 \u00b5M), consistent with the typical pharmacology of S1R agonists. Pridopidine restored mitochondrial membrane potential, reduced mitochondrial apoptotic signaling, shown by decreased BAX expression and caspase-3 activation, and improved survival of ALS-NPCs under ER stress. Co-treatment with the selective S1R antagonist, NE-100, attenuated these effects, supporting an S1R-mediated mechanism of action for pridopidine. Together, these results demonstrate that S1R activation by pridopidine mitigates ER-stress-induced mitochondrial dysfunction and cell loss in ALS-NPCs, resulting in enhanced survival of NPCs supporting the therapeutic potential of pridopidine in ALS.",

This study evaluated the effects of Cybister chinensis extracts (CCME) and Periplaneta americana residue extracts (PAE) on inflammation-associated, oxidative stress-related, and fibrosis-related responses in Crandell-Rees Feline Kidney (CRFK) cells. Using MTT assays, flow cytometry, and qPCR, we assessed cytoprotection in models of lipopolysaccharide (LPS)-, hydrogen peroxide (H2O2)-, and palmitic acid (PA)-induced injury. Preliminary HPLC fingerprint analysis of three batches of a combined extract from Periplaneta americana residues and Cybister chinensis Motschulsky (CPCE) revealed similar chromatographic profiles, indicating good batch-to-batch consistency. Within non-cytotoxic ranges, CPCE increased cell viability and reduced apoptosis in injured CRFK cells. Anti-inflammatory effects were evidenced by significant downregulation of TNF-\u03b1 and IL-6 mRNA. Potential antioxidant-related effects were suggested by decreased expression of oxidative stress-responsive genes SOD1, CAT, and GSTP1. In the PA model, anti-fibrotic potential was supported by reduced TGFB1 expression, accompanied by improvements in inflammatory and oxidative stress markers, and by decreased levels of fibrosis-associated markers \u03b1-SMA, COL I, and HCB III.

This study investigated the impact of 28 consecutive days of 5-lx ALAN exposure on hippocampal function in C57BL/6\u00a0J mice. We evaluated locomotor behavior, neuronal morphology, neurogenesis, oxidative stress, and circadian rhythms, revealing that ALAN induces cognitive impairment. ALAN exposure reduced Bmal1 expression, increased reactive oxygen species (ROS) and malondialdehyde accumulation, and disrupted the time-of-day-dependent differences expression of NRF2, SOD1, and GPX1. These alterations suppressed SOD and GPX enzymatic activity, leading to hippocampal oxidative damage. To clarify BMAL1's role, we used adeno-associated virus (AAV) to modulate Bmal1 expression in the hippocampus. ALAN increased hippocampal apoptosis, which was exacerbated by Bmal1 knockdown and mitigated by its overexpression. These findings suggest that ALAN can contribute to memory impairment by disrupting hippocampal damage and impairing neurogenesis through its effect on Bmal1. This study identifies potential molecular targets for preventing and treating cognitive impairment and neurodegenerative disorders.",

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates.",

Additionally, existing treatment methods have several problems, including high risk of complications, systemic side effects, and impact on patients' quality of life. Recently, cannabidiol (CBD), a non-psychoactive cannabinoid found in Cannabis sativa, has emerged as an alternative therapeutic medication because of its potential antitumor activity with fewer side effects. We evaluated the cell viability, clonogenicity, migration, apoptotic nuclear morphology, and cell cycle phases of C6 rat glioma, SH-SY5Y human neuroblastoma, and HT22 immortalized mouse hippocampus neuronal cultures treated with CBD ranged between 0 and 10\u00a0\u03bcg/mL. CBD concentrations exceeding 5\u00a0\u03bcg/mL induced significant reductions in cell viability in C6 glioma and SH-SY5Y neuroblastoma cultures, accompanied by decreased clonogenicity in both cultures at 10\u00a0\u03bcg/mL. A scratch assay for cell migration revealed that 5\u00a0\u03bcg/mL CBD suppressed C6 glioma cell migration. Additionally, late apoptotic nuclear morphology was observed in C6 glioma cultures treated with 10\u00a0\u03bcg/mL cannabidiol. Similarly, HT22 hippocampal neuronal cultures exhibited decreased cell viability and clonogenicity, with apparent nuclear signs of apoptosis at CBD concentrations over 5\u00a0\u03bcg/mL. Notably, CBD disrupted HT22 cell migration at concentrations of 2.5 and 5\u00a0\u03bcg/mL. Proteomic profiling of C6 glioma revealed upregulation of ribosomal proteins, molecular chaperones, and modulators of cytoskeletal dynamics upon treatment with 1\u00a0\u03bcg/mL CBD. In comparison, treatment with 2.5\u00a0\u03bcg/mL CBD led to marked downregulation of endoplasmic reticulum chaperones, mitochondrial ATP synthase, and cytoskeletal regulators. Our findings confirm the sensitivity of glioma, neuroblastoma, and hippocampal neuronal cultures to CBD, providing valuable insights for further research into its therapeutic potential against glioma, neuroblastoma, and neuronal disorders.",

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.

Here, we report that the M337V mutation in TDP43 exacerbates its proteotoxicity relative to the wild-type protein. Concurrently, multi-omics analysis revealed a pronounced downregulation of TRIM16 in motor neuron-like cells expressing either wild-type or M337V mutant TDP43. Functional studies demonstrated that TRIM16 overexpression effectively mitigated oxidative stress, restored mitochondrial integrity, and suppressed ferroptosis. Mechanistically, TRIM16 promoted the ubiquitination and degradation of Keap1, thereby facilitating the activation of Nrf2-mediated antioxidant genes. Furthermore, we identified the iron import receptor TFR1 as a novel ubiquitination substrate of TRIM16. TRIM16 mediated the ubiquitination of TFR1 and targeted it for p62-dependent autophagic degradation, which in turn reduced iron accumulation and lipid peroxidation. Collectively, our findings establish TRIM16 as a pivotal suppressor of TDP43-induced toxicity by orchestrating dual cytoprotective pathways to enhance cellular resilience, highlighting its promising therapeutic potential for TDP43 proteinopathy.",

Glial cells at the NMJ, perisynaptic Schwann cells (PSCs), ensure a balance between maintenance and repair via muscarinic receptor signaling. However, in ALS mouse models, PSCs show an aberrant muscarinic hyperactivation. We posited that this excessive activation impairs the PSC capacity to support NMJ repair in ALS. Beginning at symptoms onset, SOD1 G37R mice received daily oral administration of darifenacin, a clinically approved type 3 muscarinic receptor antagonist, to reduce PSC hyperactivation. The treatment improved locomotion and preserved NMJ innervation in male mice, with comparable effects observed in females, and extended survival in males. Functional benefits were supported by signs of glial repair and enhanced survival of lumbar motor neurons. These preclinical data indicate that pathological PSC hyperactivity contributes to NMJ denervation in ALS and support therapeutic strategies targeting NMJs in ALS.",

MT levels were elevated in plasma and hierarchy follicles yolks (P\u2009<\u20090.05). Progesterone concentrations rose in plasma (P\u2009<\u20090.05), however, estradiol levels decreased in plasma, F1 and F2 yolks (P\u2009<\u20090.05). MT also reduced ROS and MDA levels in plasma and F1 yolk (P\u2009<\u20090.05). Meanwhile, activities of SOD, TAC, and GSH-PX were significantly increased (P\u2009<\u20090.05). MT upregulated SOD1, CAT, and BCL2 mRNA levels in ovary and F1 GCL (P\u2009<\u20090.05). MT significantly increased ovarian expressions of HSD3B1 and CYP11A1, reducing HSD17B1 mRNA levels (P\u2009<\u20090.05); In F1 and F2 GCL, CYP11A1, CYP17A1, and CYP19A1 expressions were all elevated (P\u2009<\u20090.05). These findings suggest that MT promotes hierarchy follicle maturation, reduces apoptosis, thus extending egg-laying period in aging pigeons.",

Nicotinamide adenine dinucleotide (NAD+) functions as a central regulator of cellular energy metabolism. We have previously reported that downregulation of NAD+-dependent sirtuin signaling contributes to the impaired progenitor cell function of IPF AT2 cells. In this study, we found that a key NAD+ biosynthesis enzyme, nicotinamide phosphoribosyltransferase (NAMPT), was significantly downregulated in IPF AT2 cells. NAMPT deficiency impaired AT2 renewal and enhanced lung fibrosis through downregulation of SIRT7 and SOD2, which resulted in increased oxidative stress, mitochondrial dysfunction, accumulated aberrant transitional cells, and impaired differentiation from AT2 to alveolar type 1 (AT1) cells. A mouse model with AT2-specific deletion of Nampt showed severely impaired AT2 renewal capacity and increased susceptibility to bleomycin lung injury. Activation of NAMPT by small-molecule activators promoted IPF AT2 renewal and reversed lung fibrosis in WT mice. NAMPT activation is a potentially promising therapeutic strategy for restoring AT2 progenitor cell function and halting or reversing progressive pulmonary fibrosis.",

The role of free radicals in generating these protease resistant structures has been experimentally demonstrated in prion bovine spongiform encephalopathy (BSE), when manganese is substituted for copper (Cu), in bovine brain homogenates in reductive medium, while Cu protective effect against free radicals can be restored by Cu supplementation in oxidative medium. These facts can suggest a free radical-induced epimerization process in neuroprotein misfolding leading to the transformation of physiological L-amino acid brain proteins into abnormal D-structures which will be deposited in the brain as observed in neurodegenerative diseased brains. A blood Cu increase, not ceruloplasmin (CP) bound correlated with a Cu increase in the cerebrospinal fluid (CSF) and a Cu decrease in the brain have been described in AD, PD, ALS, or CJD. This indicates that following neuronal death, Cu might be expelled from brain proteins and subsequent to redistribution between brain, CSF and blood, it will result a brain Cu deficiency and a decrease in Cu brain protection against free radicals. In the aim of repairing this deficiency and slow down the neurodegenerative disease process, a brain Cu complexes vectorization through the blood-brain barrier might restore brain Cu homeostasis.",

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.",

In the present study, we explored the effects and underlying mechanisms of SiNPs exposure during in vitro maturation (IVM) of porcine oocytes. The results showed that SiNPs significantly suppress porcine oocyte maturation as evidenced by decreased first polar body (PB1) release rate. Notably, SiNPs significantly induced abnormal expansion of cumulus cells and impaired gap junction intercellular communication (GJIC), accompanied by decreased Connexin 43 (CX43) expression and aberrant F-actin structure. Furthermore, DCFH-DA staining showed that SiNPs significantly increased reactive oxygen species (ROS) levels and malondialdehyde (MDA) content, and decreased the mRNA levels of antioxidant-related genes, including SOD1, SOD2, CAT, GPX1, PRDX2, and NRF2. JC-1 staining showed that SiNPs significantly induced mitochondrial dysfunction via diminished mitochondrial membrane potential (\u0394\u03a8m) and aberrant distribution, and decreased the mRNA levels of energy metabolism-related genes, such as NOX4 and COX2. Additionally, SiNPs significantly disrupted lysosomal function and cholesterol trafficking and decreased the mRNA levels of LDLR, NPC1, NPC2, and LAMP2, leading to reduced free cholesterol levels and the mRNA levels of estrogen synthesis-related genes, including STAR, CYP19A1, and HSD-3\u03b2. Collectively, SiNPs suppress porcine oocyte maturation, at least partly, through oxidative stress, metabolic disruption, and impaired cholesterol trafficking.",

In silico analyses, including classification-based QSAR, chemical space networks, and scaffold diversity analysis on 2078 HDAC8 inhibitors uncovered essential molecular features for strong HDAC8 potency, informing the design of 12 derivatives. Docking studies ranked the top two candidates, which were subsequently derivatized, synthesized and evaluated through HDAC8 enzymatic and cytotoxicity assays. Several compounds proved highly active, with 6c exhibiting superior HDAC8 inhibition, strong antiproliferative activity against A549 cells, and minimal impact on HEK-293 normal cells. Mechanistic studies demonstrated apoptosis induction, G2/M arrest, ROS generation, and increased nuclear fragmentation. Western blot analysis confirmed intracellular HDAC8 inhibition through elevated SMC3 acetylation, while 500 ns molecular dynamics simulations supported stable binding of 6c within the HDAC8 active site. Collectively, these findings identify compound 6c as a promising HDAC8 inhibitor and potential lead candidate for the development of novel anti-lung cancer agents targeting epigenetic pathways. This work provides insights that might advance efforts to develop effective non-platinum anticancer agents.",

Following exposure, BMAA is present in both free and protein-bound forms, forming an endogenous toxin reservoir that exacerbates potential neurotoxicity in aquatic organisms and humans. Its presence in aquatic food webs not only elevates ecological risks for wildlife but also raises potential human health concerns, particularly its potential association with neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), Alzheimer's disease, and the ALS/Parkinsonism-dementia complex. This review aims to explore current knowledge of the ecotoxicological impacts of BMAA in fishes, focusing on developmental, behavioural and cognitive perturbations, along with their mechanistic underpinnings. BMAA exposure induces developmental abnormalities, including convulsions, spinal axis malformations, pericardial edema, and altered heart rate, as well as neurodevelopmental impairments, such as reduced motor neuron length and altered neuromuscular colocalization in fishes. Additionally, BMAA exposure affects a wide array of behaviours in fishes, including motor coordination, locomotion, feeding, startle responses, anxiety-like behaviours, and cognitive performance, primarily through excitotoxicity, oxidative stress, apoptosis, metabolic disruption, neuroendocrine modulation, and dysregulated neurotransmitter signalling. Future research should focus on more environmentally relevant exposure scenarios, elucidating BMAA toxicokinetics, and investigating cyanotoxin co-exposure toxicity in fishes. Advancing integrative phenotypic endpoints and knowledge of molecular mechanisms of BMAA toxicity in aquatic organisms is essential for effective ecological risk assessments and for developing regulatory standards to safeguard aquatic ecosystems and human health.",

The present study aimed to evaluate the concentration-dependent effects of DBP on morphology, cytotoxicity, oxidative stress, cell senescence, steroidogenesis and expression of related key developmental genes in cultured ovine granulosa cells in the presence of FSH. Granulosa cells were isolated from slaughterhouse-derived ovine ovaries and cultured in vitro with exposure to DBP at concentrations of 0, 1, 10, 25, 50, and 100\u202f\u00b5M. Cytotoxic responses were assessed by evaluating nuclear damage, reactive oxygen species (ROS) generation, apoptosis, and cellular senescence. In addition, expression levels of key steroidogenic genes (CYP11A1, CYP17A1, CYP19A1, STAR, HSD3B1, HSD17B1), hormonereceptors (ESR1, ESR2, PGR, FSHR), and pro-apoptotic and anti-apoptotic markers (BAX, CASP3, BCL2) were measured using quantitative PCR. Estradiol and progesterone levels were quantified in culture media to evaluate functional steroidogenic output. The results revealed that DBP exposure caused a concentration-dependent increase in ROS levels, apoptosis-related gene expression, and signs of cellular senescence, particularly at concentrations \u2265\u202f25\u202f\u00b5M. Interestingly, estradiol production increased significantly with increasing DBP concentration, despite the presence of cellular stress. Gene expression analysis showed a marked upregulation of ESR1, FSHR, and CYP19A1, while ESR2 and the other key steroidogenic genes remained unchanged. These findings suggested that DBP might altered estrogenic activity through selective modulation of estrogen and FSH receptor signaling rather than through global transcriptional activation of steroidogenic enzymes. Moreover, alterations in mitochondrial membrane potential and nuclear morphology suggested the subcellular stress responses to DBP. In conclusion, DBP exerted dual effects on ovine granulosa cells by inducing oxidative stress and cellular dysfunction while simultaneously enhancing estradiol synthesis through selective receptor pathways. FSH stimulated steroidogenesis in GCs culture in the presence of DBP, yet it was unable to mitigate DBP-induced cell toxicity.",

This work aims to characterize anticancer properties of Fe3O4 nanoparticles functionalized with glucose and co-conjugated with hyaluronic acid (HA) and Kaempferol (KAE) in triple negative breast cancer (TNBC) cells. The Fe3O4@Glu-HA-KAE NPs were characterized by FT-IR, XRD, EDS, SEM, TEM, DLS and zeta potential analyses. Cytotoxicity in MDA-MB-231 cells was evaluated using MTT assays. Apoptosis and cell cycle changes were analyzed by flow cytometry, Nuclear morphology was examined via AO/PI staining, and ROS production was measured in treated and control groups The FT-IR, XRD and EDS analyses confirmed the correct synthesis of Fe3O4@Glu-HA-KAE NPs. The NPs were spherical with a particle size of 10-60\u00a0nm in their dried form and an average diameter of 276\u00a0nm and a surface charge of -39.7 mV. Fe3O4@Glu-HA-KAE NPs exhibited dose- and time-dependent toxicity against TNBC cells and the 24-hour and 48-hour IC50 of the NPs in the MDA-B-231 cells were 215 and 149\u00a0\u00b5g/mL, respectively. In addition, the NPs caused cell cycle arrest at the sub-G1 phase, and increased cell apoptosis percentage to 65.1-68.1%. The synthesized NPs triggered significant nuclear alterations, enhanced ROS generation, and elevated cell death in TNBC cells.Furthermore, exposure to Fe\u2083O\u2084@Glu-HA-KAE NPs led to a 1.41-fold increase in Caspase-8 expression, while BCRT1 lncRNA transcript levels were markedly reduced to 0.73-fold, indicating that apoptosis-related mechanisms contribute to the observed cytotoxicity. This work demonstrates efficient anticancer properties of Fe3O4@Glu-HA-KAE NPs against TNBC cells, representing an innovative approach to combat TNBC.",
"42123994": "ID: 42123994\nTitle: Long-Chain Fatty Acids as Drivers of Neuroinflammation in Neurodegeneration: Mechanistic Links to Lipid Peroxidation, Ferroptosis, and Mitochondrial Dysfunction.\nAbstract: Background: Neurodegenerative diseases (NDs) are mainly considered disorders marked by severe immunometabolic imbalance, characterized by ongoing neuroinflammation and glial activation. While mitochondrial dysfunction and oxidative stress are well-known features, the upstream metabolic factors linking these pathological processes remain poorly understood. Methods: In this review, we examined recent preclinical and clinical studies exploring the connections between lipid metabolism, glial immunometabolism, and regulated cell death pathways. Our focus was on how long-chain fatty acids (LCFAs) facilitate communication among mitochondria, reactive oxygen species (ROS), and ferroptosis in Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). Results: New evidence shifts LCFAs from merely being passive indicators of cellular damage to active, upstream regulators of the neuroimmune response. Existing research shows that excess LCFA intake can overload astrocytic mitochondrial oxidative phosphorylation, leading to abnormal lipid droplet buildup and reactive astrogliosis. This lipid-driven reactivity promotes microglial polarization toward a persistent pro-inflammatory state. Notably, high levels of specific LCFAs, especially arachidonic acid, increase ROS production and lipid peroxidation. This lipotoxic environment ultimately triggers ferroptosis, an iron-dependent form of cell death shared across multiple NDs. Conclusions: The harmful interaction among mitochondrial dysfunction, lipid peroxidation, and ferroptosis is driven by an imbalance in LCFA levels. Addressing current challenges, such as the complex effects of polyunsaturated fatty acid supplementation, requires advanced techniques like single-cell multi-omics and artificial intelligence. Understanding this intricate lipidomic-transcriptomic crosstalk is crucial for moving toward personalized neuroimmunometabolism and developing new treatments to prevent ferroptosis.",

They predominantly appear in neutrophils, with occurrence across multiple leukocyte lineages being uncommon. We report a rare case of multilineage HJBLI in a patient with severe sepsis, describe the associated morphological features, and discuss the clinical relevance to prevent misinterpretation in routine practice. We present the case of a 23-year-old female patient with incomplete abortion complicated by severe\u00a0Escherichia coli sepsis, corroborated by positive blood and vaginal cultures alongside markedly elevated procalcitonin and C-reactive protein levels. Peripheral blood smears (\u00d71000 magnification) revealed round, densely basophilic inclusions morphologically consistent with HJBLI in neutrophils, eosinophils, and monocytes, with up to five inclusions per monocyte. Concomitant toxic changes, including prominent toxic granulation, D\u00f6hle bodies, and cytoplasmic vacuolization, were evident. Multilineage HJBLI can be detected in the setting of severe sepsis, likely resulting from sepsis-induced nuclear fragmentation and dyspoiesis. This expands HJBLI's disease spectrum; familiarity with this morphology improves accurate recognition in routine hematological examinations.",

Although the core fusion and division machinery is well established, how cells sense mitochondrial morphology and actively adjust it remains unclear. In this Opinion article, we propose a new conceptual framework, termed 'Mitochondrial Safeguard (MitoSafe)', in which cells monitor mitochondrial size and rebalance division and fusion through four branches: activation of fusion or inhibition of division in small mitochondria and activation of division or inhibition of fusion in enlarged mitochondria. Recent findings show that fusion is suppressed once mitochondria exceed a healthy size threshold. Dysregulation of this branch of MitoSafe, involving Parkin, PINK1, SLC25A3, SOD1, and cytochrome-c oxidase, causes mitochondrial enlargement, mitochondrial DNA release, and stimulator of interferon genes (STING)-mediated inflammation.",

These disorders lead to cognitive, motor, and sensory decline, significantly reducing quality of life and posing a major global health burden due to rising healthcare costs and the absence of curative therapies. This review aims to comprehensively explore the therapeutic potential of natural products in targeting cellular and molecular mechanisms underlying NDs, highlighting their neuroprotective roles and potential for disease modification. A comprehensive literature review was conducted using databases including PubMed, Scopus, Web of Science, and Google Scholar. Peer-reviewed articles, clinical trials, and experimental studies were analyzed to evaluate the therapeutic potential of natural products and their bioactive compounds in the management of NDs. ND pathogenesis involves oxidative stress, neuroinflammation, mitochondrial dysfunction, and abnormal protein aggregation, ultimately leading to neuronal death. Current therapies largely provide symptomatic relief without altering disease progression. Natural products from plants, fungi, and marine sources demonstrate strong neuroprotective potential through multitargeted mechanisms. Bioactive compounds such as flavonoids, alkaloids, terpenoids, and polyphenols exhibit antioxidant, anti-inflammatory, anti-apoptotic, and neuroprotective activities. Key molecules, including curcumin, resveratrol, luteolin, quercetin, and catechins, modulate signaling pathways such as NF-\u03baB, MAPK, PI3K/AKT, Nrf2, apoptosis, and autophagy, thereby reducing amyloid-beta aggregation, protecting dopaminergic neurons, improving mitochondrial function, and enhancing cognition in preclinical and clinical studies. Natural products represent promising candidates for disease modification in NDs due to their multi-pathway actions and relatively low toxicity. However, major limitations, such as poor bioavailability, pharmacokinetic variability, and the lack of standardized formulations, hinder clinical translation. Innovative strategies, including advanced drug-delivery systems, structural modifications, and synergistic formulations, are needed to overcome these barriers. Natural products hold significant therapeutic potential in managing neurodegenerative diseases by targeting multiple pathological mechanisms. Their integration into ND treatment could provide safer and more effective alternatives, but further well-designed clinical trials are essential to establish their efficacy and facilitate clinical application.",

Tartrazine was reported to induce hepatotoxicity, however, the effects of tartrazine on nuclear factor erythroid two-related factor two (Nrf2) signaling and endoplasmic reticulum (ER) stress pathways in rat liver have not been investigated. Therefore, this study aimed to investigate the effects of tartrazine on Nrf2 signaling and ER stress pathways in rat liver, to examine the potential therapeutic effects of lycopene, quercetin, and silymarin, and to investigate the mechanisms through which they may mitigate tartrazine-induced liver injury. Rats were allocated into five experimental groups including a normal control group and a tartrazine group that received tartrazine (10 mg/kg) orally for 13 weeks. The lycopene, quercetin, and silymarin groups received tartrazine (10 mg/kg) for 13 weeks and were treated with lycopene (10 mg/kg), quercetin (50 mg/kg), and silymarin (150 mg/kg), respectively, for the last 8 weeks. Tartrazine-induced liver injury was characterized by increased alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase serum levels and histopathological changes in the liver. Furthermore, tartrazine suppressed hepatic Nrf2 signaling and induced ER stress. Hepatic levels of malonaldehyde and caspase-3 were increased, while the levels of superoxide dismutase activity and glutathione and B cell lymphoma-2 were decreased. Moreover, hepatic transforming growth factor-beta one levels and collagen deposition were increased. Treatment with lycopene, quercetin, and silymarin ameliorated the tartrazine-induced changes, upregulated Nrf2 signaling and alleviated ER stress. Our findings suggest that lycopene, quercetin, and silymarin may provide a promising therapeutic approach against tartrazine-induced liver injury.",

Mounting evidence indicates that dysregulated iron metabolism and an imbalance in antioxidant defenses can induce ferroptosis in neurons and glial cells while simultaneously remodeling immune cell function, thereby establishing a bidirectional feedback loop that amplifies neuroinflammation and tissue damage. In neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), pro-inflammatory cytokines such as TNF-\u03b1 and IL-1\u03b2 released by activated microglia upregulate neuronal iron transporters (e.g., DMT1 and TfR1), promoting iron accumulation and ferroptotic cell death. In turn, damage-associated molecular patterns released from ferroptotic cells further potentiate immune activation, forming a self-amplifying cycle. In contrast, within the glioma microenvironment, CD8+ T cell-derived IFN-\u03b3 suppresses SLC7A11 expression in tumor cells, leading to glutathione depletion and glutathione peroxidase 4 inactivation, thereby triggering ferroptosis and modulating anti-tumor immunity. Although targeting ferroptosis or neuroimmune pathways has shown therapeutic promise in mitigating neurological deficits and enhancing anti-tumor responses, the underlying mechanisms governing ferroptosis-immune crosstalk remain inadequately characterized. Herein, this review systematically summarizes the key biological characteristics of ferroptosis and immune responses, with particular emphasis on their interplay across major CNS disorders (i.e., AD, PD, ALS, multiple sclerosis, stroke, and glioma). Furthermore, we discuss emerging therapeutic strategies encompassing small molecules, immunomodulatory approaches, and nanotechnology-based interventions, highlighting the ferroptosis-immune axis as a promising therapeutic target for CNS diseases.",
"42148602": "ID: 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.",

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.

Traditional risk stratification is based on the genetic classification in the 2022 guidelines of the European Leukemia Net. However, the risks of some patients remain unclear, and other prognostic assessment methods are required to improve the risk assessment of these patients. Apoptosis-related genes (ARGs) play critical roles in regulating the survival and drug resistance of AML cells. Therefore, we collected gene expression and clinical data from patients with AML from The Cancer Genome Atlas Acute Myeloid Leukemia (TCGA-LAML) datasets to develop a risk assessment model based on 5 ARGs. Using the least absolute shrinkage and selection operator Cox regression (LASSO-Cox) model, we identified 5 key ARGs (DDIT4, HSP90B1, ENO1, SOD1, and SLC7A11) and constructed a 5-ARG prognostic model. Using this model, we successfully stratified patients in both TCGA-LAML training and independent external validation cohorts, with high-risk patients consistently exhibiting significantly poorer clinical outcomes. In addition, high-risk patients exhibited significant enrichment in pathways related to TP53 dysfunction, mechanistic target of rapamycin complex 1 (mTORC1) signaling activation, and pro-inflammatory responses, which were closely correlated with NPM1c-FLT3 co-mutations. Decitabine, sunitinib, and MK-1775 were identified as potential therapeutic agents. In summary, we established a 5-ARG prognostic model that may facilitate risk stratification and inform therapeutic decision-making in AML.",

The effect of the extract on the molecules involved in the cell signaling mechanism was evaluated using western blotting and PCR. Calyx extract cytotoxicity presented by the MTT assay at a 2.8\u00a0mg IC50 value, with atypical nuclear morphology and reduced cell migration. Rosella crude extract influences ECM1 glycoprotein, AKT1, and Cyclin D1 suppressing colony-forming ability. Apoptosis gets triggered, resulting in upregulation of different caspases, BID, and suppression of Bcl-2.

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.",
"42173382": "ID: 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.",

We established a D-galactose-induced ageing model in rats and observed the daily behaviour of the rats. Using staining methods to detect ROS, apoptosis and histopathological changes in liver and brain tissue. Determination of antioxidant levels of IL-2, IL-6 and AGES in rats. Assessment of cognitive function using the Morris water maze and ChAT. The mRNA and protein expression levels of Nrf2, Bach1, SOD1, SOD2, HO-1 were determined by real-time PCR and Western blotting. To investigate the role of the Nrf2/Bach1-ARE pathway, we used ML385, a specific inhibitor of the Nrf2 pathway, to treat rats in the inhibitor group. Aging rats showed impaired learning and memory, along with decreased levels of neurotransmitters and antioxidant enzymes. ATX and vitamin E (VE) interventions significantly alleviated these symptoms and activated the Nrf2/Bach1-ARE pathway in liver and brain tissues of aged SD rats. Furthermore, the protective effects of ATX were attenuated by the addition of the Nrf2 inhibitor ML385. ATX reduces oxidative stress and ameliorates liver and brain damage in aged rats via activation of the Nrf2/Bach1-ARE pathway.",
"42177838": "ID: 42177838\nTitle: Obesity suppresses neutrophil-dependent itaconate signaling promoting ferroptosis in acute pancreatitis.\nAbstract: Obesity is a well-established risk factor for increased severity and mortality in acute pancreatitis. However, the mechanisms by which obesity alters pancreatic immune regulation and favors the progression of acute pancreatitis are not elucidated yet. Here, we identify a neutrophil-driven immune-metabolic pathway that controls ferroptosis during pancreatic inflammation. We show that infiltrating myeloid cells represent the principal source of the immunometabolite itaconate during acute pancreatitis. Through paracrine transfer via the SLC13A3 transporter, myeloid-derived itaconate protects pancreatic acinar cells from ferroptosis by sustaining NRF2-dependent antioxidant responses. Obesity disrupts this protective axis by suppressing ACOD1 expression in infiltrating neutrophils. Proteomic profiling of pancreatic neutrophils from obese mice confirmed reduced ACOD1 abundance and decreased expression of enzymes linked to the tricarboxylic acid cycle and pyruvate metabolism. This metabolic reprogramming limits itaconate production and weakens NRF2-driven redox defenses, leading to downregulation of the xCT-GPX4 ferroptosis-protective pathway and increased lipid peroxidation in the pancreas of obese mice with pancreatitis. Pharmacological restoration of itaconate signaling with the cell-permeable derivative 4-octyl itaconate reactivates NRF2 signaling, the xCT-GPX4 antioxidant axis, and the trans-sulfuration pathway, mitigating pancreatic injury. Together, these findings identify neutrophil-derived itaconate as a key modulator of ferroptosis susceptibility and reveal immune cell metabolism as a critical determinant of obesity-associated severity in acute pancreatitis.",
"42178013": "ID: 42178013\nTitle: Design, synthesis, and inhibition of oxidative, amyloidogenic, and cholinergic dysfunction of saxagliptin-derived schiff bases against STZ-induced sporadic AD-like pathology.\nAbstract: Alzheimer's disease (AD) shares significant pathological convergence with diabetes, primarily through insulin resistance. This leads to oxidative stress, neuronal inflammation, plaque formation, cholinergic dysfunction, and impaired neuronal survival. Herein, we report 10 Saxagliptin (SXG, a potent DPP-IV inhibitor)-derived Schiff base derivatives that were virtually designed and screened. Five leads were prioritized using ADMET profiling and molecular docking, then synthesized via Schiff base condensation with selected aryl aldehydes to target AD progression associated with diabetes. Structural integrity, redox activity, and stability were confirmed by comprehensive characterization, including chromatographic and spectroscopic analyses, DFT calculations, and in vitro antioxidant assays. Neuroprotective potential was thus assessed in vivo by inducing AD-like pathology in rats with a single i.p. dose of STZ at 45\u202fmg/kg, thereby reproducing brain insulin resistance, oxidative-nitrosative stress, and cholinergic dysfunction. Significant neurodegeneration in STZ-treated rats was evidenced by behavioral analyses, biochemical markers (AChE, A\u03b242), oxidative stress indices (SOD, CAT, GSH, GPx, MDA, NO, MPO), and hippocampal histology. Treatment with SXG and derivatives at 0.5\u202fmg/kg, orally, resulted in significant restoration of antioxidant defenses, inhibition of lipid peroxidation and NO overproduction, reduction of inflammatory oxidative bursts, and improved cognition in treated groups. Remarkably, derivatives 3c and 3e showed superior free-radical scavenging and greater regulation of redox biomarkers, which were associated with healthy, defined hippocampal cytoarchitecture and reduced neuronal pyknosis and necrosis compared with SXG. Additionally, 3e showed strong therapeutic efficacy by targeting oxidative stress, cholinergic, and amyloidogenic pathways synchronously.",
"42183665": "ID: 42183665\nTitle: Expanding the phenotypic spectrum of SOD1\u2011related ALS: upper motor neuron predominance in a p.D91A case.\nAbstract: Mutations in superoxide dismutase 1 SOD1 are the second most common genetic cause of ALS, usually associated with prevalent lower motor neuron phenotypes. We describe a 66-year-old woman with slowly progressive spastic paraparesis, initially diagnosed as primary lateral sclerosis, who carried a heterozygous p.D91A mutation. Clinical and neurophysiological findings indicated predominant upper motor neuron involvement, an unusual presentation for this mutation. This case broadens the SOD1 phenotypic spectrum and highlights the importance of early genetic testing in atypical motor syndromes, given the availability of targeted therapies where diagnostic delay may limit benefit. Amyotrophic lateral sclerosis (ALS) is a disease that affects the nerve cells that control muscle movement. Some of these nerve cells (called \u201clower motor neurons\u201d) send signals directly to muscles, allowing us to move. In some people, ALS is caused by changes in specific genes, including one called SOD1.We describe the case of a 66-year-old woman who gradually developed stiffness and weakness in her legs. Because her symptoms mainly involved stiffness and progressed slowly, she was initially diagnosed with primary lateral sclerosis (PLS), a condition that affects a different group of nerve cells (the \u201cupper motor neurons\u201d) and usually has a slower course. At that time, she underwent genetic testing, but only for genes linked to hereditary spastic paraplegia, a different group of disorders, and no mutations were found.When she was later evaluated in our center, additional tests\u2014including electromyography (a test that studies muscle and nerve function) and detailed neurological examination\u2014suggested ALS. Genetic analysis then identified a specific mutation in the SOD1 gene (called p.D91A).Interestingly, her symptoms were mainly related to upper motor neuron involvement, which is unusual for this mutation.This case shows that SOD1-related ALS can present in unexpected ways, making diagnosis challenging. It also highlights the importance of considering broader genetic testing, even in patients without a family history or with atypical symptoms. Early diagnosis is increasingly important, as new treatments are now available and may be more effective when started sooner.",
"42184491": "ID: 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.",

Folic acid (FA) and E-yeast (a deactivated form of Saccharomyces cerevisiae combined with wheat germ oil) are natural dietary supplements that may help mitigate these adverse effects. To compare the cardioprotective, antioxidant, anti-inflammatory, histological, and gut microbiota-modulating effects of FA and E-yeast on DOX-induced cardiac toxicity in rats. Twenty-four rats were divided into four groups: control, DOX-treated, FA\u2009+\u2009DOX, and E-yeast\u2009+\u2009DOX. The cardiac biomarkers lactate dehydrogenase and creatine kinase-MB (LDH, CK-MB), oxidative stress markers (malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPX), inflammatory mediators (IL-6, TNF-\u03b1, IFN-\u03b3, NLrp3), and fecal short-chain fatty acids (SCFAs) (acetic, butanoic, and propionic acids) were measured. In addition, left ventricular echocardiography and cardiac and colonic histology, including cardiac NADPH oxidase 4 (NOX4) expression, were assessed. DOX induced cardiac dysfunction, as shown by increased cardiac enzymes, left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic diameter (LVEDD) and decreased ejection fraction and SCFAs. Additionally, it increased the levels of MDA, IL-6, TNF-\u03b1, IFN-\u03b3, and NLrp3. Folic acid restored cardiac, echocardiographic, oxidative, and inflammatory parameters to normal levels, whereas E-yeast only partially improved these parameters. SCFAs were restored to normal by both treatments. Histologically, DOX caused cardiomyocyte degeneration, necrosis, and increased NOX4 expression, resulting in degenerative disruption of the colonic mucosa. Folic acid was more effective at preserving the myocardial architecture and NOX4 expression, whereas E-yeast was more effective at minimizing colonic degenerative lesions. Folic acid demonstrated a more pronounced healing effect than did E-yeast on DOX-induced cardiac alterations.",

"42186564": "ID: 42186564\nTitle: Dual roles of two Tfdps in germline nuclear meiosis and somatic nuclear fragmentation during sexual reproduction in the unicellular organism Paramecium tetraurelia.\nAbstract: Meiosis is regulated by phase-specific genes to orchestrate nuclear and cytoskeletal dynamics essential for sexual reproduction. The ciliate Paramecium tetraurelia exhibits nuclear dimorphism, harboring two germline micronuclei (MICs) and one somatic macronucleus (MAC) within a single cell during vegetative growth. During sexual reproduction, the MICs undergo meiosis and the MAC deforms and fragments, providing a unique model to study the regulation of diverse nuclear events. Transcription factor DP (TFDP), which heterodimerizes with E2Fs, can bind to specific DNA motifs in promoters of cell cycle-regulated genes to activate or repress their expression. Here, we identified 16 TFDP homologs in P. tetraurelia, representing an exceptional gene family expansion accompanied by functional domain diversification. The functions of Tfdp1a and Tfdp1b, which are specifically expressed during sexual reproduction and localize in the old and new MACs, were further investigated. Their depletion resulted in meiotic arrest at metaphase in the MIC, failure of old MAC fragmentation, and abortive cytokinesis. Transcriptomic analysis revealed that TFDP1A/1B knockdown primarily causes gene downregulation, with\u2009>\u200960% of downregulated genes being specifically highly expressed during sexual reproduction. Functional annotation and enrichment analyses demonstrated significant downregulation of proteins involved in meiosis, DNA replication, and DNA repair. Critically, multiple downregulated meiotic regulators are essential for proper homologous chromosome segregation and sister chromatid separation, providing a mechanistic basis for the observed MIC meiotic arrest. This study uncovers Tfdp1a/1b as essential regulators of the distinctive meiotic process in P. tetraurelia, providing crucial insights into nuclear dynamics and the regulation of sexual reproduction in binucleate systems.

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.",

Phenolic antioxidants derived from plants, including eugenol (EG), represent a promising strategy to reduce the detrimental effects of reactive oxygen species (ROS) accumulation and improve embryo development outcome. This study investigated the concentration-dependent effects of EG on the in vitro maturation (IVM) of dromedary camel cumulus-oocyte complexes (COCs). COCs were cultured in IVM medium containing 0 (control), 10, 20, 40, and 80\u00a0\u03bcM EG. Supplementation with 10 or 20\u00a0\u03bcM EG significantly increased oocyte maturation rates compared with control, whereas supplementation with 40 or 80\u00a0\u03bcM EG provided no additional benefit. Immunofluorescence analysis showed that all EG-treated groups exhibited a significant increase in lipid content and mitochondrial activity. However, the effect was significantly greater at 10 and 20\u00a0\u03bcM. Assessment of the spent IVM media showed that superoxide dismutase (SOD) and catalase (CAT) levels were significantly increased at 20\u00a0\u03bcM EG, while malondialdehyde (MDA) levels were reduced at 10 and 20\u00a0\u03bcM relative to the control. Additionally, cumulus cells recovered from oocytes matured with 10 and 20\u00a0\u03bcM EG displayed increased transcript levels of BCL2, CAT, IGF1, and SOD1 genes. Collectively, these findings indicate that EG at 10 and 20\u00a0\u03bcM may enhance IVM of camel oocytes by promoting nuclear maturation, cumulus expansion, mitochondrial activity, and lipid accumulation, accompanied by increased transcript levels of BCL2, CAT, IGF1, and SOD1.",

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.",

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.",

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.",

Human AML MOLM-13 cells were treated with gradient concentrations (0, 120, 240, 480 \u03bcmol/L) of loganetin for 48 hours. CDK2 protein expression and its interaction with KLHL6 were analyzed by Western blot and co-immunoprecipitation (Co-IP), respectively. Cellular morphology was observed via Giemsa staining. Intracellular oxidative stress was evaluated by NBT assay. An AML mouse model was established by tail-vein injection of MOLM-13 cells (1\u00d7107/mL, 2\u00d7106 cells/mouse); bone marrow cells were analyzed by flow cytometry for hCD45+ and CD11b+ surface markers. Loganetin dose-dependently induced KLHL6-mediated CDK2 ubiquitination and degradation. The Western blot analysis results showed that the level of CDK2 protein significantly decreased with the increase of loganetin concentration (P <0.01), Co-IP confirmed that the CDK2-KLHL6 interaction was enhanced in a dose-dependent manner. Giemsa staining revealed morphological changes (e.g., multinucleated cells, nuclear fragmentation) indicative of chromosome instability in high-concentration groups (480 \u03bcmol/L).

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.",
"42236747": "ID: 42236747\nTitle: Targeting mitophagy for neuroprotection: mechanisms and therapeutic opportunities.\nAbstract: Mitochondria are essential for neuronal energy production, cellular homeostasis, and overall neuronal function. Due to their high metabolic demands and limited regenerative capacity, neurons are particularly vulnerable to mitochondrial dysfunction, which leads to ATP depletion, excessive reactive oxygen species (ROS) production, and calcium imbalance-ultimately causing oxidative stress, metabolic disruption, and neuronal death. Mitophagy is a selective process that removes damaged mitochondria through the autophagy-lysosome pathway. As a key mechanism of mitochondrial quality control, mitophagy preserves energy production, limits oxidative damage, and maintains mitochondrial network integrity. This process is regulated by pathways such as PINK1-Parkin and receptor-mediated mechanisms involving BNIP3 and FUNDC1, all of which help sustain cellular health by preventing mitochondrial dysfunction. Impaired mitophagy is a common feature of several neurodegenerative diseases, including Alzheimer's, Parkinson's, amyotrophic lateral sclerosis (ALS), and Huntington's disease, exacerbating mitochondrial damage and neuronal stress. Emerging therapeutic strategies that target mitophagy-ranging from pharmacological agents and gene therapies to dietary interventions-show promise in restoring mitochondrial quality and protecting neurons from degeneration. Nevertheless, challenges remain in translating these findings into effective clinical treatments. Mitophagy represents a critical mechanism for preserving neuronal integrity and offers a compelling target for innovative therapies against neurodegenerative disorders.",
"42240799": "ID: 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.",
"42242586": "ID: 42242586\nTitle: Early-onset neuroinflammation drives neurodegeneration caused by lysosomal PI(3,5)P2 insufficiency.\nAbstract: Phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2] is a lysosomal signaling lipid whose deficiency, caused by mutations in the PIKfyve complex subunits FIG4 or VAC14, underlies a spectrum of fatal neurologic diseases including Charcot-Marie-Tooth type 4J (CMT4J) and amyotrophic lateral sclerosis (ALS). To map the molecular consequences of PI(3,5)P2 insufficiency in the brain, we performed quantitative proteomic and transcriptomic analyses of three mouse lines bearing distinct loss-of-function mutations in Fig4 or Vac14, examining the brain at the presymptomatic and end stages. Strikingly, profound neuroinflammation was already present at postnatal day 5 (before significant neurodegeneration), characterized by complement activation, interferon signaling, and parenchymal infiltration of peripheral myeloid cells and T-cells. Isolated mutant microglia exhibited a markedly pro-oxidative transcriptional state with elevated reactive oxygen species, a partly non-cell-autonomous phenotype, being present in microglia from mice with conditional Fig4 inactivation in just neurons and astrocytes. Comparison of early (P5) and late (P25) proteomics data revealed that PI(3,5)P2 insufficiency impairs developmental remodeling of the brain proteome: proteins typically upregulated during postnatal maturation failed to accumulate, implicating lysosomal function in neurodevelopment. We identify coordinated elevation of p53, Fas receptor, inflammatory caspases, Gasdermin D, RIPK1, and ZBP1, consistent with multifactorial inflammatory cell death with features of apoptosis, pyroptosis, and necroptosis. Many of the dysregulated proteins are encoded by genes mutated in lysosomal storage disorders, ALS, CMT, Alzheimer's and Parkinson diseases, extending the pathogenic relevance of PI(3,5)P2 insufficiency. Together, these findings establish that early neuroinflammation is a defining - and likely initiating - feature of neurodegeneration caused by disruption of lysosomal PI(3,5)P2.",

Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS.",

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.",
"42250949": "ID: 42250949\nTitle: Calcium overload induces reactive oxygen species to enhance glioblastoma radiosensitivity.\nAbstract: Radiotherapy is the primary treatment of glioblastoma, but its efficacy is often limited by tumor cell resistance to radiation. Radiotherapy mainly has its cytotoxic effect through the formation of reactive oxygen species and the damage to DNA. Nevertheless, to overcome the effects of reactive oxygen species- mediated oxidative damage and endoplasmic reticulum stress, tumor cells may activate the repair mechanisms to stress and improve antioxidant defenses. This study innovatively proposes the use of the calcium ionophore ionomycin as a radiosensitizer in glioblastoma. We used U87MG and U251 cell lines as well as subcutaneous xenograft mice as models, and conducted a combined intervention of ionomycin and radiotherapy. Mechanistically, ionomycin selectively disrupted endoplasmic reticulum calcium homeostasis, inducing severe and sustained endoplasmic reticulum stress. When combined with radiotherapy, this led to a marked surge in intracellular reactive oxygen species, and significantly enhanced apoptosis. In vitro, the combination treatment synergistically reduced cell viability, clonogenicity, and proliferation compared with either monotherapy. In vivo, ionomycin combined with radiotherapy substantially suppressed tumor growth and increased intratumoral reactive oxygen species levels and apoptosis. These findings indicate that ionomycin converts repairable adaptive stress into irreversible lethal damage by amplifying reactive oxygen species through an endoplasmic reticulum stress-reactive oxygen species vicious cycle, thereby overcoming antioxidant defenses and enhancing glioblastoma radiosensitivity.

"42252558": "ID: 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.",

Chelation therapy remains the principal therapeutic strategy for reducing lead toxicity through enhancement of metal elimination from blood and tissues. Deferoxamine (DFO), an iron chelator, has demonstrated protective effects against multiple heavy metals. This study evaluates the hepatoprotective and nephroprotective effects of DFO following lead-induced toxicity in Wistar rats. Six groups were studied: a control group receiving 2\u2009mL/kg of normal saline, and five lead-exposed groups (40\u2009mg/kg lead acetate for one week) treated with saline, DFO (200\u2009mg/kg), DFO (400\u2009mg/kg), EDTA (50\u2009mg/kg), or a combination of DFO (400\u2009mg/kg) and EDTA (50\u2009mg/kg) for one-week post-poisoning. Oxidative stress markers, cell viability, DNA damage, and histopathological changes in liver, kidney, and blood samples were assessed. The results demonstrated that DFO alone or in combination with EDTA significantly reduced oxidative stress, improved antioxidant enzyme levels (glutathione, catalase, and superoxide dismutase), decreased malondialdehyde levels, minimized DNA damage, and enhanced cell viability compared to untreated lead-poisoned rats. Histological analysis corroborated these findings, showing marked tissue protection. DFO at 400\u2009mg/kg, alone or combined with EDTA, showed the strongest protection against lead-induced hepatotoxicity and nephrotoxicity.",
"42261159": "ID: 42261159\nTitle: The Pivotal Role of HDAC6 in Amyotrophic Lateral Sclerosis: Neuroprotective Protagonist or Degenerative Adversary?\nAbstract: The review specifically examines the pivotal role of HDAC6 in the pathophysiological pathway of Amyotrophic Lateral Sclerosis (ALS), an escalating neurodegenerative ailment marked by the discerning damage to motor neurons. Several lines of evidence implicate inadequate proteostasis in significantly influencing neuronal degeneration. The accumulation of misfolded proteins and proteotoxicity are highlighted as significant factors in ALS pathophysiology. Key pathological hallmarks include ubiquitin-positive inclusions, disrupted RNA metabolism, cytoskeletal perturbations, and compromised axonal transport systems. HDAC6 dysregulation disrupts axonal transport, impairing mitochondrial function and increasing oxidative stress, leading to rapid motor neuron damage and cell death. The enzyme's aberrant deacetylation of \u03b1-tubulin destabilizes microtubules and impairs intracellular trafficking. Despite HDAC6's participation in these unfavorable processes, it also exerts neuroprotective properties. It deacetylates tubulin, promoting efficient axonal transport and autophagic clearance. HDAC6 helps form aggresomes and stress granules, which are essential for cellular defence against proteotoxic stress. Through its zinc finger ubiquitin-binding domain, HDAC6 interacts with polyubiquitinated proteins, facilitating their autophagic degradation. HDAC6 inhibition can boost autophagic flux and reduce protein aggregation, while its activation may amplify the protective effects. This dichotomous behaviour of HDAC6 may pose an obstacle to the design of targeted therapy. Illuminating the complex mechanisms through which HDAC6 influences neurodegeneration and neuroprotection is important before constructing effective treatments for ALS. The review provides a clear understanding of the complex role of HDAC6 in ALS pathogenesis and highlights potential strategies to improve the prognosis of people affected by this neurological illness.",

SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies.",

This review provides a unified framework to understand the interrelated molecular mechanisms driving these diseases, with a focus on identifying key disease-specific intervention nodes. Core contributors include oxidative stress, mitochondrial dysfunction, protein aggregation, neuroinflammation, and emerging roles of peroxisomal dysfunction in redox imbalance, lipid dysregulation, and inflammatory amplification. Single-target therapies often show limited efficacy due to the complex, interconnected nature of these pathways. In contrast, polypharmacology, which targets multiple disease-relevant mechanisms simultaneously, offers a more promising therapeutic strategy. This review critically examines how pathway crosstalk drives neurodegenerative progression, with particular emphasis on mitochondrial-ROS-inflammatory signaling, aggregation-proteostasis failure, synaptic-neuroimmune dysfunction, and gut-brain communication. It evaluates various multi-node intervention strategies, including multi-target-directed ligands (MTDLs), molecular hybrids, natural products, drug repurposing, and nanocarrier-based delivery systems. Advances in network pharmacology, artificial intelligence (AI), bioinformatics, and multi-omics have enhanced the identification of actionable therapeutic nodes, candidate compounds, and brain-targeted delivery platforms. Notably, the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathways-play distinct roles in neuroinflammation, amplifying neuronal damage by releasing inflammatory cytokines and inducing mitochondrial dysfunction. However, successful translation into clinical practice remains constrained by challenges such as blood-brain barrier penetration, patient heterogeneity, and biomarker limitations. The review advocates for a shift towards mechanism-informed, patient-stratified polypharmacological strategies to better address the network pathology of neurodegeneration, despite significant translational hurdles.",

This study evaluated antioxidant activities in seminal plasma and sperm cytosols and investigated their relationships with selected sperm functional parameters following cryopreservation, with or without antioxidant supplementation. Semen was collected from ten fertile stallions and processed using a split-ejaculate design, including fresh semen and six freezing treatments: HF-20 extender alone; HF-20 supplemented with matcha, spirulina, horseradish, or quercetin; and a commercial extender (INRA Freeze). Total antioxidant capacity (FRAP) and enzymatic activities (superoxide dismutase, SOD; catalase, CAT; and glutathione reductase, GR) were measured in seminal plasma and sperm lysates. Linear regression analyses revealed significant associations between seminal plasma and fresh spermatozoa with respect to SOD and GR activities. In frozen-thawed semen, FRAP and CAT activities differed between samples cryopreserved with and without antioxidant supplementation. Significant correlations were observed among antioxidant activities, sperm kinetics, OS markers, and DNA fragmentation indices. Principal component analysis provided an exploratory overview of multidimensional patterns of covariation among sperm kinetics, redox balance, and nuclear fragmentation, explaining for 73% of the total variance. Overall, the results suggest complex associations between the antioxidant system and sperm quality and indicate that antioxidant supplementation of freezing extenders may modulate the redox status of stallion sperm after thawing.",

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.

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.",
"42299014": "ID: 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.",

It is also potentially toxic while maintaining life activities: once intracellular free copper increases or becomes imbalanced, it may trigger a cascade of stress responses, including protein misfolding, disruption of redox homeostasis, and mitochondrial dysfunction. Therefore, the body maintains copper homeostasis through fine-tuned uptake, transport, storage, and efflux systems, ensuring copper remains in dynamic balance. Tumor cells often undergo adaptive changes in metal ion homeostasis in response to metabolic reprogramming and microenvironmental selective pressures. Abnormal copper metabolism has been considered closely related to tumor development, invasion, metastasis, and treatment tolerance. In recent years, cuproptosis has provided a new theoretical framework for studying the relationship between copper and tumors. Our manuscript expounds on the therapeutic value of copper and cuproptosis in tumor progression and treatment, providing a new entry point for updating accurate cancer treatment strategies.",

Tofersen treatment for superoxide dismutase-1-related (SOD1) ALS marks a pivot in clinical management: for the first time, clinicians can target disease stabilization and functional recovery in some individuals. This advancement shifts the focus of ALS care toward optimizing functional recovery alongside symptomatic management. However, there are no evidence-based guidelines for prescribing neuromuscular rehabilitation (NMR) to improve functional recovery. Building on our preliminary single-center data of integrated NMR with tofersen, we propose a new ALS Recovery Model System of Care, utilizing a hub-and-spoke infrastructure to combine NMR with novel therapies. This model aims to define ALS recovery, characterize recovery profiles, standardize NMR protocols, and establish a rehabilitation framework adaptable to future disease-stabilizing therapies.",

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.",

While complete intestinal epithelial loss of BECLIN1 causes fatal enteritis originating in the small intestine, the consequences of its partial loss in the gut remain unclear. Given that BECLIN1 expression can vary in human disease, we investigated whether reduced BECLIN1 is sufficient to impair gut barrier function. Heterozygous Becn1 deletion (Becn1IEC+/-) in the mouse intestinal epithelium caused subtle but significant defects. These included shortened small intestines and altered epithelial architecture, despite preservation of basal autophagy, implicating trafficking-related functions. Supporting this conclusion, Becn1IEC+/- small intestinal epithelial cells showed modest increases in RAB5+ve vesicles, redistribution of E-CADHERIN and F-actin along lateral membranes and altered apico-basal cell morphology. Given the absence of overt small intestinal epithelial disruption or inflammation, as seen with complete loss of BECLIN1, we next addressed whether BECLIN1 insufficiency manifests a phenotype under stress or in other gut regions. Indeed, in the colon, Becn1IEC+/- mice exhibited reduced colonic crypt length, baseline goblet cell loss and reduced mucin production, particularly in mature goblet cells, indicating vulnerability of the mucus barrier. When challenged with dextran sulfate sodium (DSS), Becn1IEC+/- mice exhibited greater weight loss, higher disease activity, more severe histological colitis, and disproportionate loss of neutral mucins, with inflammation confined to the mucosa. Together, these findings show that BECLIN1 insufficiency does not trigger spontaneous inflammation but destabilises epithelial organisation and barrier defence, thereby sensitising the gut to inflammatory challenge and further positioning BECLIN1 as a threshold-dependent determinant of intestinal resilience.",

However, the thalamus comprises multiple nuclei with distinct functions, and whether specific nuclei show differential vulnerability remains unclear. To investigate the characteristics of intra-thalamic nuclear atrophy in T1DM and evaluate its association with disease duration. 3.0\u2009T/T1-weighted magnetization-prepared-rapid-acquisition-of-gradient-echo (MPRAGE). Prospective. Forty-two subjects with T1DM (18-68\u2009years, 17 males/25 females) and 39 healthy controls (18-69\u2009years, 16 males/23 females). Multi-atlas-based segmentation was used to quantify volumes of 20 thalamic nuclei. Additionally, volumes of anatomical and functional subregions were derived based on topographic and functional nuclear classifications. Group differences were assessed using general linear models. Associations between thalamic volume loss and disease duration were evaluated via partial correlations and exponential regression models to estimate duration-related atrophy rates. p value <\u20090.05 was considered significant. Participants with T1DM showed significant bilateral reductions in total thalamic volume (left: 7.6%, Cohen's d\u2009=\u20090.91; right: 8.0%, Cohen's d\u2009=\u20090.95). The most pronounced atrophy was observed in the anterior, medial, and lateral thalamic subregions, with volume reductions of 15.8%, 8.6%, and 7.3%, respectively, particularly in cognition- and motor-related nuclei (9.4% and 9.2%, respectively). Longer disease duration was significantly associated with smaller thalamic volumes in the bilateral whole thalamus (rleft\u2009=\u2009-0.48 and rright\u2009=\u2009-0.46), as well as in the Pul (rleft\u2009=\u2009-0.64 and rright\u2009=\u2009-0.57), VLp (rleft\u2009=\u2009-0.39 and rright\u2009=\u2009-0.38), and MD-Pf nuclei (rleft\u2009=\u2009-0.55 and rright\u2009=\u2009-0.37), and in the left LGN (r\u2009=\u2009-0.43). Estimated disease-duration-related annualized atrophy rates exceeded age-related rates in several left-sided nuclei, including the MD-Pf (-0.67%), Pul (-0.69%), and LGN (-0.75%). T1DM is associated with spatially heterogeneous atrophy of thalamic nuclei, with preferential involvement of the anterior, medial, and lateral subregions. Disease duration seems to accelerate neurodegenerative changes. 2. Stage 2. This study investigated changes in thalamic nuclei associated with type 1 diabetes mellitus (T1DM). Previous studies have not clarified whether all thalamic nuclei are equally affected in T1DM. Thalamic structural changes were compared between patients with T1DM and healthy controls, and their associations with disease duration were analyzed. Patients with T1DM showed spatially heterogeneous volume loss across thalamic nuclei, with greater shrinkage in cognitive\u2010 and motor\u2010related subregions.

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.",

Therefore, the primary objective of this research work was to formulate a curcumin nanoemulgel to increase the solubility and therapeutic efficacy of curcumin and evaluate its cytotoxic, apoptotic, and Reactive oxygen species (ROS) activities against various cell lines. A curcumin nanoemulgel was formulated by adding the optimized curcumin nanoemulsion to plain carbopol gel and then subjected to various evaluation studies. The optimized curcumin nanoemulgel exhibited better growth suppression of cancer cell lines, especially in A431 squamous cell carcinoma cells, with an inhibition percentage of 66.52\u2009\u00b1\u20091.3% an IC50 value of 123.30\u2009\u00b5M. Flow cytometry analysis revealed that curcumin nanoemulgel promoted apoptosis, with larger percentages of late apoptotic cells in A431 cells. The dual AO/EB fluorescence microscopy revealed distinctive apoptotic characteristics, including chromatin condensation, nuclear fragmentation, membrane blebbing, and the formation of apoptotic bodies. All of these results demonstrate that the nanoemulgel formulation is a superior therapeutic choice as it not only enhances curcumin's anticancer effectiveness but also ensures its safety in healthy cells.",

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.",

Our understanding of the mechanisms of irAE in the brain is still evolving, and we recently demonstrated that ICI (blockade of CTLA-4 and PD-1) perturbs hippocampal-dependent memory function by derailing neuro-immune homeostasis and compromising synaptic integrity. However, the spatial patterns and the cell-type-specific molecular mechanisms underlying ICI-related brain dysfunction remain not well-defined. To address this gap, we performed spatial transcriptomic profiling of the hippocampal region using multiplexed error-robust fluorescence in situ hybridization (MERFISH) to map gene expression at single-cell resolution. By integrating spatial single-cell data with bulk RNA-seq, we define the distribution of microglia, astrocytes, synaptic, and neuroinflammatory markers, and determine how ICI reshapes hippocampal cellular composition in a syngeneic murine melanoma model. MERFISH revealed upregulation of microglial, astrocytic, oligodendrocytic, and T cell markers post-ICI treatment, revealing unique pathways driving neuroinflammation, synaptic function, and cellular signaling. Furthermore, immunofluorescence analysis of postmortem brains from patients treated with ICI corroborates our findings of ICI-related immune activation of microglia. Finally, using a conditional deletion model, we show that T cells are indispensable for ICI-driven microglial activation. Altogether, our study provides a high-resolution spatial framework for understanding irAEs in brain function and a T cell-microglia crosstalk axis as a driving mechanism of dysregulated neuro-immune homeostasis during ICI.",
"42327318": "ID: 42327318\nTitle: Mutant SOD1 expressed by oligodendrocytes aggregates in myelinic nanochannels and accelerates disease progression in familial ALS mice.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a highly debilitating and fatal disease characterized by the progressive loss of motor neurons. Reduced oligodendroglial support has been implicated in ALS progression but remains mechanistically unexplained. Here, using a mutant superoxide dismutase 1 (SOD1-G37R) mouse model of familial ALS, Cre-mediated excision of the mutant SOD1 gene within the oligodendrocyte lineage prior to myelin compaction is shown to slow disease onset, improve motor performance, and prolong survival. In contrast, silencing mutant SOD1 expression within oligodendrocytes after myelin compaction failed to ameliorate disease phenotype. Electron microscopy is used to identify aggregation of mutant SOD1 within paranodal loops and the inner periaxonal tongue of 'myelinic nanochannels', narrow cytosolic compartments for the diffusion of metabolites and motor-driven transport processes. In a second mouse model (SOD1-G93A) of familial, SOD1 mutant-mediated ALS, we show that induction of excessive myelin compaction and myelinic channel collapse (by depletion of CNP from myelin) accelerates disease and diminishes survival. Our data support loss of myelinic channel integrity as a contributor to familial ALS disease initiation and progression, findings likely relevant to neurodegenerative disease involving other aggregation prone proteins that are expressed in myelinating oligodendrocytes. Oligodendrocytes have been implicated in the progression of amyotrophic lateral sclerosis (ALS) but the underlying mechanisms have remained obscure. Here we show in genetic mouse models that the familial ALS causing isoform of a ubiquitously expressed mutant enzyme (SOD1) aggregates in cytosolic channels within myelin that are responsible for delivery of transporters and nutrients necessary to support the axonal compartment. ALS disease progression was accelerated in mice when myelinic channels were collapsed by deleting CNP, a structural protein necessary for myelinic channel maintenance.

This study aimed to unravel the role of PARylation in \u03b1-synuclein aggregation and neuronal cell death in the complex environment of post-mortem human PD brains. Using high-resolution imaging and 3D reconstruction analysis, we observed that PAR accumulate in the cytoplasm in regions affected by PD pathology, preceding the formation of \u03b1-synuclein oligomers. Additionally, we found that PAR and stress granules contribute to the formation of Lewy bodies. Increased colocalization of PAR with mitochondria in the substantia nigra of PD patients, along with the presence of PAR-positive condensed DNA, further suggests a role in neuronal cell death. Collectively, our findings reveal a critical involvement of PARylation in the pathological mechanisms underlying neurodegeneration in PD and position PARylation as a potential therapeutic target.",
"42332177": "ID: 42332177\nTitle: Trace Elements Dyshomeostasis and Toxic Metals Neurotoxicity in Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, are defined by the progressive loss of neurons through interconnected pathological mechanisms, including oxidative stress, mitochondrial dysfunction, protein aggregation, and neuroinflammation. Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases.",

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.",
"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). 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.",
"42343570": "ID: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology.",

Neuronal cell injury is a major factor in neurodegenerative diseases. There seems to be rising interest in developing effective neuroprotective drugs from natural sources. Nutraceuticals, or compounds produced from natural sources have shown neuroprotective effects in both in vitro and in vivo models of neuronal cell death and neurodegeneration. Carnosic acid (CA), a natural compound majorly obtained from rosemary and other herbs, has emerged as a promising neuroprotective agent in neurodegenerative diseases, particularly Alzheimer's and Parkinson's. This review covers the latest findings on the methods by which carnosic acid mitigates key pathological features such as oxidative stress, neuroinflammation, apoptosis, and protein aggregation as well as other pathways related to Parkinson's and Alzheimer's disease induction. Furthermore, we describe preclinical and clinical research that demonstrates the ability of carnosic acid to improve cognitive function and motor performance. This study will give a detailed overview of carnosic acid as a possible therapeutic agent, opening the path for future research into viable therapies for Alzheimer's and Parkinson's disorders.",

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.",
"42350373": "ID: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.",

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.",
"42351313": "ID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.",

This review explores the intricate relationship between mitochondrial function and neuronal health, emphasizing the pivotal role of the solute carrier family 25 (SLC25) transporters in maintaining mitochondrial homeostasis. We provide a comprehensive overview of mitochondrial biology in the central nervous system, including energy metabolism, calcium signaling, redox regulation, organelle interactions and mitochondrial dynamics. We delve into the SLC25 transporter family, highlighting their transport mechanisms, substrates and roles in brain metabolism and neuroprotection. SLC25 on one hand and proteins involved in the regulation of mitochondrial morphology and calcium signaling on the other hand are two sides of the same coin influencing each other. A critical analysis follows, examining how mitochondrial dysfunction contributes to mitochondrial abnormalities in a spectrum of neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, ALS and rare mitochondrial encephalopathies. Finally, we assess emerging therapeutic strategies targeting mitochondrial pathways and SLC25 function, including metabolic modulation, gene therapies, antioxidants and pharmacological agents. This review underscores mitochondria and the SLC25 transporters as promising targets for disease-modifying interventions in neurodegeneration and raises key questions about the causality between mitochondrial failure and neuronal death.",

Protein palmitoylation is a dynamic and reversible lipid post-translational modification that controls protein membrane association, trafficking, stability, and signaling complex assembly. This review summarizes the regulatory roles of palmitoylation and depalmitoylation in major forms of regulated cell death, including apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagy-related cell death. Particular attention is given to representative palmitoylated substrates, including Fas cell surface death receptor (Fas), receptor-interacting protein kinase 1 (RIPK1), NLR family pyrin domain containing 3 (NLRP3), gasdermin D (GSDMD), glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), autophagy-related 16 like 1 (ATG16L1), and Beclin1. These substrates illustrate how palmitoylation links membrane organization, metabolic status, inflammatory signaling, and cell fate decisions. Disease-oriented evidence further indicates that dysregulated palmitoylation contributes to cancer, neurodegenerative diseases, and inflammatory or immune-related disorders by modulating cell death resistance, inflammatory amplification, immune evasion, or impaired proteostasis. Current challenges include limited quantitative information on palmitoylation dynamics, incomplete evidence for some enzyme-substrate relationships, and insufficient distinction between disease-driving and secondary palmitoylation events. Targeting zinc finger Asp-His-His-Cys (zDHHC) palmitoyl acyltransferases, depalmitoylating enzymes, or specific palmitoylated substrates may provide new therapeutic opportunities. Overall, this review positions protein palmitoylation as a dynamic molecular switch linking lipid metabolism, membrane signaling, regulated cell death, and disease remodeling.",
"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.",

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.",
"42353197": "ID: 42353197\nTitle: Hesperetin Rescues Amyloid Beta-Induced Defects in Neurite Outgrowth Under In Vitro Mild Cognitive Impairment-like Cellular Conditions.\nAbstract: Accumulation of aggregated amyloid beta (A\u03b2) species is a defining pathological hallmark of Alzheimer's disease and is associated with extensive neuronal structural abnormalities. Mild cognitive impairment (MCI), a transitional stage between normal aging and the onset of dementia, is thought to represent an early phase of this pathological continuum. Studies at the cellular level suggest that the conditions impair the maintenance of established neuronal processes/networks and restrict their capacity for elongation or re-elongation. They may also attenuate the activation and process extension of quiescent neural progenitor or stem-like cells. These early cellular changes precede overt neurodegeneration in neural tissue and are likely to contribute to cognitive decline. They highlight the importance of in vitro models for identifying molecular targets involved in recovery from disease. In this study, we investigated the effects of aggregated A\u03b2 (25-35) on neuronal process elongation and associated intracellular events in the N1E-115 cell line, a widely used model of neuronal differentiation. Addition of aggregated A\u03b2 to cultured N1E-115 cells attenuated process elongation in a concentration-dependent manner. This morphological impairment was accompanied by decreased expression of neuronal differentiation markers. In contrast, at the half-maximal inhibitory concentration for process elongation, long-term cultured cells did not exhibit apparent process retraction or degenerative morphology. This mild but progressive impairment, without extensive cell death, is consistent with the cellular features of early-stage conditions rather than advanced Alzheimer's pathologies. Similar results were observed in primary cortical neurons. A\u03b2 also decreased the level of GTP-bound Ras and phosphorylation of the downstream mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK). Furthermore, treatment with hesperetin, a bioactive flavonoid compound, recovered the A\u03b2-induced inhibition of neuronal process elongation. Hesperetin also restored Ras and MAPK/ERK states, suggesting that its effects are associated, at least in part, with modulation of signaling through Ras and MAPK/ERK. Our findings suggest that hesperetin may serve as a useful molecular probe for modulating early cellular responses associated with Alzheimer's disease-related pathology. This in vitro model might serve as a useful platform for investigating the molecular target candidates involved in recovery from nervous system disorders.",

A comparative study was conducted to analyze the effects of probiotics and IF on SD-induced neuropsychological disturbances and compromised muscle endurance. Forty albino Wistar rats were randomly assigned to four groups. The NSD group was maintained on a standard chow diet for 12\u00a0weeks. The SD group followed an SD regimen for 72\u00a0h per week over 8\u00a0weeks, starting from the fifth week. The SDP group received probiotics at a dose of colony-forming units (CFUs)/100\u00a0g/day for 4\u00a0weeks prior to SD, followed by 8\u00a0weeks of concurrent probiotic administration with SD. The SDIF group underwent an alternate-day fasting regimen for 4\u00a0weeks before SD, followed by 8\u00a0weeks of simultaneous SD combined with IF. Neuropsychological functions and exercise capacity were tested, and then the brains were carefully dissected, sectioned, and processed for hematoxylin and eosin, cresyl violet, and immunohistochemical staining. Inflammatory markers, including interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1), and hippocampal expression of the circadian locomotor output cycles kaput (CLOCK) gene, were significantly elevated in the SD group. Conversely, it showed significant decreases in endurance, exploratory behavior, hippocampal superoxide dismutase (SOD) activity, and fecal short-chain fatty acids (SCFAs). Histological analysis also revealed hippocampal gliosis, apoptosis, CA1 pyramidal cell degeneration, layer disorganization, and upregulation of glial fibrillary acidic protein (GFAP), NF-\u03baB, and cleaved caspase-3. Nevertheless, both probiotics and IF markedly reduced serum MDA, hippocampal CLOCK gene expression, gliosis, and apoptosis and enhanced memory performance. In addition, they significantly increased hippocampal SOD activity and SCFAs. These findings indicate that prophylactic probiotics decrease cognitive disruption and impaired muscle endurance caused by SD through CLOCK gene regulation compared to that with IF. This highlights the need for further research to elucidate these mechanisms. Histological findings also supported these results, showing improved neuronal structure in the hippocampus following probiotic treatment.",

GH3 cells were exposed to tigecycline ranging from 6.25 to 100\u2009\u03bcM. Cell viability and IC50 were determined using the CCK-8 assay, and spheroid growth was monitored by measuring diameters. To assess apoptosis, cells were subjected to Annexin V-FITC/PI staining and nuclear morphology observation after DAPI staining. Meanwhile, the cell cycle distribution was profiled via flow cytometry following propidium iodide (PI) staining. The expression of proteins related to the Akt/mTOR pathway, apoptosis, and growth hormone (GH) was evaluated by Western blot. GH secretion was quantified using ELISA. Tigecycline dose and time dependently suppressed GH3 cell proliferation, with IC50 values of 22.45\u2009\u03bcM at 48\u2009h and 9.037\u2009\u03bcM at 72\u2009h. It also impeded three-dimensional spheroid growth. Mechanistically, treatment induced G0/G1 phase arrest, significantly suppressed the Akt/mTOR signaling pathway (evidenced by reduced phosphorylation of Akt and mTOR), and activated the intrinsic apoptotic pathway, marked by a rise in the Bax/Bcl-2 ratio and heightened cleaved caspase-3 expression. Additionally, tigecycline significantly attenuated both intracellular synthesis and extracellular secretion of GH. These findings indicate that tigecycline exerts potent antiproliferative and antisecretory effects on GH3 cells, likely through Akt/mTOR pathway inhibition, cell cycle arrest, and apoptosis induction. These results provide an experimental foundation for considering tigecycline as a potential therapeutic agent for GH-secreting PitNET.",

This study aimed to investigate the protective effects of colchicine on diet- induced vascular remodeling, focusing on caspase-1-dependent inflammatory signaling, caspase-3/gasdermin E (GSDME)-mediated cell death pathways, and toll-like receptor 4 (TLR4) signaling modulation. Forty adult male C57BL/6 mice were categorized into four groups: control, colchicine-treated (0.25\u202fmg/kg/day, i.p.), hypercholesterolemic, and hypercholesterolemic plus colchicine (0.25\u202fmg/kg/day, i.p.). Mice were sacrificed after 12 weeks, and blood samples were collected. Thoracic aortic specimens were prepared for subsequent biochemical, molecular, histological, and ultrastructural analysis. Colchicine administration significantly improved serum lipid profiles and modulated tissue oxidative stress by decreasing (1.8-fold) malondialdehyde (MDA) levels and increasing (1.75-fold) superoxide dismutase (SOD) levels. Colchicine significantly downregulated the mRNA expression levels of caspase-1 (2.4-fold), interleukin-1 beta (IL-1\u03b2) (3.6-fold), specificity protein 1 (SP1) (3.0-fold), signal transducer and activator of transcription 3 (STAT3) (2.4-fold), GSDME (3.3-fold), and TLR4 (2.6-fold) in the aortic samples, accompanied by near-normal immunohistochemical expression of caspase-3 and IL-1\u03b2. Furthermore, colchicine effectively preserved aortic wall structure, diminished fibrosis, and attenuated ultrastructural damage associated with inflammatory cell death. Colchicine displays protective effects against diet-induced vascular remodeling in mice, associated with the modulation of inflammatory and cell death pathway markers, alongside ultrastructural improvements. These findings support its therapeutic potential for mitigating vascular injury relevant to atherosclerosis, though further mechanistic validation is required.",

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.",

Defined as a distinct, integrative form of cell death, PANoptosis simultaneously engages these three pathways through a multiprotein scaffold known as the PANoptosome, ensuring robust elimination of infected, damaged, or transformed cells. Initially described in response to viral infections, PANoptosis is now recognized as a critical regulator of immune defense, inflammation, and tissue homeostasis, with broad implications for infectious diseases, cancer, autoimmune disorders, neurodegeneration, and ischemia-reperfusion injury. This review provides a comprehensive overview of the molecular composition of the PANoptosome, key triggers of PANoptosis, and its morphological and biochemical hallmarks. We further discuss its dual roles as both a protective and pathogenic mechanism, highlighting context-dependent contributions to host defense and disease progression. Finally, we examine therapeutic opportunities, including small-molecule inhibitors and gene-editing approaches, and outline current challenges, such as the identification of reliable biomarkers and the need for precision-targeted strategies. By integrating recent advances, this review highlights PANoptosis as a conceptual shift in cell death biology and a promising avenue for novel interventions in inflammation-driven diseases.",

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.

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.

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.",

Many patients suffer treatment-related side effects such as pain, diarrhea, and myelosuppression, and increasing tolerance of treatment has the potential to improve outcomes. BMX-001, a superoxide dismutase mimetic, is currently in clinical trials as a selective radioprotector for anal and rectal cancer; however, the mechanism by which BMX-001 exerts selective radioprotection of healthy tissue over cancer tissue, particularly when administered at physiologically achievable doses, is not well understood. BMX-001 was given before and during chemoradiation and did not interfere with chemoradiation-induced cancer cell killing in mouse models. In vitro, BMX-001 still induced cancer cell killing in the presence of exogenous catalase, suggesting that BMX-001's anti-tumor activity is not solely reliant on hydrogen peroxide production. BMX-001 exerted robust acute radioprotection in radiation mouse models five and nine days post-radiation. To assess whether BMX-001's protection is contingent on Nrf2 expression, we evaluated the effect of BMX-001 on 5-FU treated mouse bone marrow, where Nrf2 is crucial to maintaining hematopoietic stem cell niches. Interestingly, BMX-001 could still exert some chemoprotection in mice without functional Nrf2. To assess whether BMX-001 had any functional effects on protein oxidation status, we performed mass spectrometry analysis to evaluate sulfenylated proteins in bone marrow treated with 5-FU in wildtype mice and mice without Nrf2. We found that BMX-001 given before 5-FU treatment resulted in the sulfenylation of CRTC2 and CBP, two proteins involved in CREB signaling and known to enhance Nrf2 activity. We also found that BMX-001 with 5-FU treatment enhanced DPYD sulfenylation, a protein known to detoxify 5-FU, and ALDH7A1 sulfenylation, a protein known to detoxify aldehydes. Together, these results suggest that BMX-001 can protect against oxidative stress in normal tissue via Nrf2 dependent and independent mechanisms.",

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.",

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.",

However, the roles of PANoptosis-related genes in PD remain unclear. We performed two-sample Mendelian randomization (MR) using cis-eQTL instruments from the eQTLGen Consortium for 30 PANoptosis-related genes, with PD GWAS data from Nalls et al. 2019 as the outcome. Instrumental variables were selected using a hierarchical strategy, with genome-wide significant cis-eQTLs as primary instruments and a relaxed threshold applied only for genes with fewer than three independent SNPs. Sensitivity analyses included MR-Egger, weighted median, MR-PRESSO, MR-RAPS, and leave-one-out analyses. SMR/HEIDI testing and two-step MR mediation using 731 peripheral immune traits were also performed. Genetically predicted higher CXCL16 expression was associated with increased PD risk (OR\u2009=\u20091.115, 95% CI 1.060-1.173, p\u2009=\u20092.4\u2009\u00d7\u200910-5), while higher FADD expression was associated with reduced PD risk (OR\u2009=\u20090.861, 95% CI 0.790-0.939, p\u2009=\u20097.1\u2009\u00d7\u200910-4). CASP1 and IFI27 were nominally significant and considered exploratory. Sensitivity analyses were directionally consistent, although MR-Egger estimates were imprecise. SMR/HEIDI supported CXCL16. Exploratory mediation analysis identified 63/66 candidate immune mediators after FDR correction. These findings provide MR-based genetic evidence linking CXCL16 expression to PD risk, with exploratory mediation through peripheral immune phenotypes. The CXCL16-immune cell-PD axis warrants further experimental validation.",

This deficiency results in mitochondrial dysregulation, oxidative stress, and progressive cell death. Currently, only one approved treatment exists for FRDA in the United States, Canada, and the European Union, which improves neurological outcomes but has not been fully evaluated for broader disease symptoms. Therefore, identifying new therapeutic targets remains essential. Sphingolipids are increasingly recognized for their roles in neurodegeneration with emerging evidence indicating their dysregulation in FRDA. Here, we investigate whether sphingolipid-metabolizing enzymes are similarly affected and assess the therapeutic potential of targeting them. Our findings demonstrate that these enzymes are dysregulated across multiple FRDA models. Importantly, their modulation in vitro and in vivo significantly reduces mitochondrial dysfunction, enhances frataxin expression, and improves key pathological features of the disease, highlighting sphingolipid metabolism as a promising therapeutic target for FRDA.",

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). 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.",
"42385702": "ID: 42385702\nTitle: Recurrent patterns of TOP1-mediated neuronal genomic damage shared by major neurodegenerative disorders.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD) represent two major categories of neurodegenerative disorders-TAR DNA-binding protein 43 (TDP-43) and tau proteinopathies-for which the mechanisms driving neuronal death remain unclear. Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.",

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 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), 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 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, 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.",
"42389275": "ID: 42389275\nTitle: Role of gut microbiota in melanosis coli: from anthraquinone biotransformation to mucosal homeostasis dysbiosis.\nAbstract: Melanosis coli (MC) is a benign and usually reversible condition characterized by brownish-black pigmentation of the colonic mucosa and is commonly associated with chronic exposure to anthraquinone laxatives (ALs). The best-established histopathological sequence involves AL-related epithelial apoptosis, phagocytosis of apoptotic bodies by macrophages, and subsequent lipofuscin deposition. Emerging evidence suggests that the gut microbiota (GM) may contribute to this process by converting pharmacologically inactive anthraquinone glycosides into active anthrone metabolites, including rhein anthrone. This narrative review summarizes available MC-specific findings and clearly distinguishes them from mechanistic hypotheses extrapolated from constipation, intestinal barrier, and microbiome literature. We discuss microbial \u03b2-glucosidases and reductases involved in AL biotransformation, reported changes in microbial diversity and SCFA-producing taxa in MC or constipation-associated cohorts, and plausible links with barrier dysfunction, bile-acid metabolism, tryptophan-derived metabolites, and LPS-TLR4 signaling. We therefore present the \"Microbiota-Apoptosis Axis\" as a proposed framework rather than a validated causal pathway. Finally, we review GM-targeted strategies, including probiotics, synbiotics, and fecal microbiota transplantation, while emphasizing that direct clinical evidence in MC remains limited and that cessation of anthraquinone laxatives remains the primary management strategy.",

We hypothesized that a 2.5\u2009Gy dose would induce mitotic failure and cell death, whereas low doses (<1\u2009Gy) might elicit adaptive or hormetic responses. Human U-87\u2009MG glioblastoma cells were cultured on coated glass-bottom dishes, stained with Hoechst 33,342, and maintained at 37\u00b0C/5% CO\u2082. A custom agarose phantom with an embedded dish and metal grid enabled precise delivery of graded SRS doses. CT-based planning localized the dish in the Leksell Gamma Knife Perfexion\u00ae. A single 50% isodose shot delivered 2.5\u2009Gy at the central grid cell (C9), generating adjacent compartments with 2.0, 1.5, 1.0, 0.8, and 0.5\u2009Gy. Live confocal imaging was performed at baseline and at 0, 3, 6, and 24\u2009h post-irradiation. Total cell number and mitotic cells (condensed chromosomes) were quantified per field. Three independent experiments were analyzed using two-way ANOVA with Tukey's post hoc test (\u03b1\u2009=\u20090.05). At 2.5\u2009Gy, cell numbers declined to near zero by 6\u2009h (Mean normalized adherent nuclear count decreased to approximately 5% of baseline.), associated with marked nuclear abnormalities, including multinucleation and nuclear fragmentation. Mitotic figures were absent at all post-SRS time points. Intermediate doses (1.0-1.5\u2009Gy) caused a transient delay: cell counts increased (up to ~150% at 3-6\u2009h, p\u2009<\u20090.05) before declining by 24\u2009h. In contrast, low doses (0.5-0.8\u2009Gy) resulted in net proliferation. The 0.8\u2009Gy group showed a 182% increase in cell count at 24\u2009h (p\u2009=\u20090.01), with a peak mitotic fraction (~12%) at 6\u2009h versus ~2% in controls (p\u2009<\u20090.01). These findings are consistent with radiation hormesis. Two-way ANOVA confirmed significant effects of dose and time (p\u2009<\u20090.001). To our knowledge, this is the first study integrating live-cell imaging with GKRS isodose mapping to assess temporal cellular responses to stereotactic radiosurgery. Gamma Knife SRS induces a dose-dependent response in GBM cells: high doses abolish proliferation, whereas sub-therapeutic doses paradoxically stimulate cell-cycle progression. These findings highlight a potential clinical concern, as low-dose regions may transiently promote tumor growth, but may also be exploited to enhance radiosensitivity.",

Herein, we report a systematic evaluation of the anticancer activity of a series of rhodium- and iridium-based NHC (N-heterocyclic carbene) complexes (complexes 1, 3, 5-7), including the novel complex 3, as well as two imidazole-containing complexes (2 and 4). Their cytotoxic profiles were investigated against B16-F10 melanoma cells and benchmarked against non-cancerous RAW 264.7 macrophage cells to assess cancer selectivity. Cytotoxicity of complexes 1-7 was quantified using the crystal violet assay following exposure to 0.01\u00a0mM and 0.1\u00a0mM concentrations over 24, 48, and 72\u00a0h. Half-maximal inhibitory concentrations (IC50) were determined to establish comparative selectivity and potency indices. Mechanistic insight was further obtained through morphological assessment of treated cells at IC50 values using polarised light optical differential interference contrast (PlasDIC) microscopy. At 0.1\u00a0mM, all complexes induced a pronounced reduction in B16-F10 cell viability, with complexes 2 and 3 emerging as the most potent, achieving >90% inhibition after 72\u00a0h. Notably, early time-point IC50 values (24\u00a0h) revealed marked cytotoxicity in melanoma cells (complex 2: 0.04\u00a0mM; complex 3: 0.05\u00a0mM), while eliciting minimal effects in RAW 264.7 macrophages, indicating selective anti-cancer activity. Morphological analysis of B16-F10 cells demonstrated features consistent with both apoptosis (membrane blebbing, apoptotic bodies, nuclear fragmentation) and necrosis (cell swelling, debris). Cell cycle analysis demonstrated a general increase in the S phase in B16-F10 cells, indicative of replication stress or cell cycle arrest, whereas no significant changes were observed in RAW 264.7 cells. Collectively, complexes 2, 3, and 5, display a compelling combination of potency and selectivity towards B16-F10 melanoma cells, with reduced cytotoxicity towards non-cancerous RAW 264.7 cells. These results support the continued development of NHC-based metal complexes as promising selective anticancer agents and warrant further mechanistic and in vivo investigation.",

HGC-27 cell xenografts were established in Balb/c-nu mice. After tumor formation, mice were allocated into a low-dose(7.5 g\u00b7kg~(-1) per day) JHJD group, a high-dose(15 g\u00b7kg~(-1) per day) JHJD group, and a model group. The mice in the JHJD groups were administrated with corresponding doses of JHJD and those in the model group with an equal volume of normal saline by gavage. The body mass, subcutaneous xenograft volume, and tissue mass of the mice were measured, and the tumor inhibition rate was calculated. The pathological changes of the xenograft tissue in each group were observed under a microscope after hematoxylin-eosin(HE) staining. The ROS level in the tissue was measured by a ROS kit, and the mRNA levels of PARP1 and GSDME in the xenograft were determined by RT-qPCR. HGC-27 cells were assigned into 5%, 10%, and 15% blank serum groups and 5%, 10%, and 15% JHJD-containing serum groups. Cell viability was detected by the CCK-8 assay, and intracellular ROS levels were quantified by the ROS kit. The morphological changes of cells were observed under a microscope. The protein levels of PARP1 and GSDME were determined by Western blot. The lactate dehydrogenase(LDH) release rate and adenosine triphosphate(ATP) levels in the cell supernatant were determined by LDH and ATP kits, and high mobility group box-1 protein(HMGB1) levels in the cell supernatant were determined by ELISA. In vivo experiments revealed that the low-and high-dose JHJD groups had lower volume and mass of subcutaneous xenografts than the model group(P<0.05), with the tumor inhibition rates of 20.43% and 30.75%, respectively. HE staining showed that cells in the model group exhibited pleomorphism, clustered arrangement, and nuclear division. Cells in the low-dose JHJD group showed reduced nuclear volume, deeply stained nuclei, lack of mitotic figures, and numerous vacuoles. Cells in the high-dose JHJD group showed nuclear pyknosis, nuclear fragmentation, and numerous cell debris. The mRNA levels of PARP1 and GSDME and the levels of ROS in the tissue in both the low-dose and high-dose JHJD groups raised compared with those in the model group(P<0.05). In vitro experiments showed that serum containing JHJD at all concentrations inhibited the proliferation of HGC-27 cells at the time points of 24, 48, and 72 h(P<0.05), and the inhibitory effect increased in a concentration-dependent manner. Morphological features of pyroptosis, including swelling, rupture, and release of vesicular contents at the cell edges, were induced by JHJD-containing serum to varying degrees, being the most pronounced in the 15% JHJD-containing serum group. The ROS levels and the protein levels of PARP1 and GSDME in all JHJD-containing serum groups were higher than those in the 5% blank serum group(P<0.05), and the differences between JHJD-containing serum groups were significant(P<0.05). Compared with the 5% blank serum group, JHJD-containing serum increased the LDH release rate and the ATP and HMGB1 levels in the supernatant(P<0.05) in a concentration-dependent manner, and the differences between groups were significant(P<0.05). In conclusion, JHJD may inhibit the proliferation of gastric cancer HGC-27 cells by inducing pyroptosis through upregulating the ROS/PARP1/GSDME pathway.",

Aspirin-induced human gastric mucosal epithelial cell(GES-1) model and gastric mucosal injury model of mice were employed. The CCK-8 assay was used to detect the impact of different concentrations of Xftg on the viability of GES-1. Cell morphology was detected by using Hoechst 33342 fluorescent staining. Hematoxylin-eosin(HE) staining was employed to observe the mouse gastric tissue morphology. The expression levels of zonula occludens-1(ZO-1) and Occludin were detected by immunofluorescence. Mucin 2(MUC2) expression was measured via immunohistochemistry. Levels of interleukin(IL)-6, IL-1\u03b2, tumor necrosis factor-\u03b1(TNF-\u03b1), cyclooxygenase(COX)-1, and prostaglandin E2(PGE2) in serum were determined by enzyme-linked immunosorbent assay(ELISA). Target proteins were screened by using limited enzymatic digestion. The level of glycogen phosphorylase B(PYGB) in gastric tissue was determined by ELISA. Protein expression in gastric tissues was detected by Western blot. The results show that Xftg in vitro increases the viability and ameliorates nuclear fragmentation of aspirin-induced GES-1. In vivo, Xftg alleviates the weight loss of model mice with gastric mucosa injury and pathological damage of the gastric mucosa. It also increases the expression of Occludin and ZO-1 proteins in gastric tissue, normalizes MUC2 protein expression, elevates levels of COX-1 and PGE2 in serum, and reduces levels of IL-6, IL-1\u03b2, and TNF-\u03b1 in serum. PYGB is identified as a potential target of Xftg by using limited enzymatic digestion. ELISA and Western blot experiments confirm that Xftg significantly downregulates PYGB protein expression in the gastric tissue of mice. In conclusion, Xftg may inhibit aspirin-induced gastric mucosal injury effect by targeting PYGB and downregulating PYGB protein expression.",
"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.",
"42398881": "ID: 42398881\nTitle: Mitochondrial Dysfunction and Diabetic Retinopathy: Research Progress from Pathogenic Mechanisms to Therapeutic Targets.\nAbstract: Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes mellitus (DM) and remains a major cause of visual impairment and blindness in adults. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.",

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.",

Despite its pathological role, effective therapies remain limited by the lack of safe, potent molecules targeting TDP-43 neurotoxicity. Here we show that the conserved \u03b1-helical region spanning residues 320-340 (conserved region or CR) is a therapeutically actionable target for TDP-43 neurotoxicity. Deletion of CR markedly suppressed TDP-43-induced neuronal death. Structure-based virtual screening identified XL20, a brain-penetrant small molecule that engages CR and confers neuroprotection without affecting TDP-43 splicing activity. XL20 alleviated motor neuron loss, extended survival in TDP-43 p.Ala315Thr ALS mice and enhanced neuronal function in p.Gln331Lys induced pluripotent stem cell-derived human ALS motor neurons. Mechanistically, targeting CR suppressed TDP-43 mitochondrial localization and restored mitochondrial function, likely through liquid-liquid phase separation. Our findings highlight CR as a therapeutic target for TDP-43-associated neurodegeneration and support CR-binding small molecules as therapeutic candidates.",

Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.",
"42400823": "ID: 42400823\nTitle: Update on Genetic Chorea.\nAbstract: Chorea is a symptom of numerous pathophysiologically and clinically heterogeneous genetic conditions. A number of developments have been made in this field over the last years linked to improved genomic testing, large cohort collaborations and improved understanding of the molecular mechanisms. This review aims to provide an update on the new genetic conditions and phenotypes linked to chorea disorders, their modification factors and pathophysiological background. Several novel genetic conditions have been linked to chorea over the last 3 years, including mutations in FTH1, NAA60, ACBD6 or TOR1AIP2. Also, novel phenotypes have been established and linked to chorea, such as Adult-onset Neurodegeneration in Nucleotide Excision Repair Disorder (NERD-ND). Major advances have been made in understanding of the pathophysiological role of somatic instability in HD. Striatal pallidal neurons (SPNs) with 150-500\u2009+\u2009CAG repeats seem to lose positive and then negative features of neuronal identity, de-repress senescence/apoptosis genes, ultimately leading to cell death. Improved recognition of the genetic background of chorea leads to more effective diagnostic processes, better prognostication and improved personalized treatment. The findings on somatic instability in HD suggest that neurodegeneration in HD is an asynchronous DNA process for >95% of a neuron's life, with majority of neurons in all disease stages having a HTT gene which is not biologically harmful. This has potential major therapeutic implications not only in HD but also in other neurological repeat expansion disorders.",
"42402732": "ID: 42402732\nTitle: Alcohol-induced structural and cellular brain alterations: molecular and histopathological mechanisms.\nAbstract: Chronic alcohol consumption is a leading cause of acquired neurodegeneration with well-documented structural and ultrastructural brain alterations. This review analyzes the cellular and molecular mechanisms underlying alcohol neurotoxicity, integrating findings from animal models, human post-mortem studies, and neuroimaging investigations. Ethanol crosses the blood-brain barrier and generates toxic metabolites including acetaldehyde and reactive oxygen species, triggering oxidative stress, lipid peroxidation, and mitochondrial dysfunction. Chronic exposure induces glutamatergic and gamma-aminobutyric acid (GABA)ergic adaptations leading to excitotoxicity during withdrawal. Cell death occurs through apoptotic, necrotic, and necroptotic pathways, while microglial and astrocytic activation perpetuates neuroinflammation. Histopathological (HP) changes include selective neuronal loss in the prefrontal cortex, hippocampus, and cerebellum, dendritic simplification, and synaptic alterations. White matter pathology manifests as demyelination and axonal degeneration. Associated thiamine deficiency produces characteristic lesions in the mammillary bodies, thalamus, and cerebellar vermis. Neuroimaging techniques provide valuable HP correlates and biomarkers for disease monitoring. While some changes demonstrate partial reversibility with abstinence through remyelination and synaptic plasticity, extensive neuronal loss remains irreversible. Understanding these mechanisms is essential for developing neuroprotective therapeutic strategies.",
"42402967": "ID: 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.",

The folic acid antagonist, Methotrexate (MTRX), has tremendous applications in the treatment of various tumors, autoimmune disorders, and inflammatory diseases, but hepatotoxicity limits its clinical use. This study aimed to investigate the role of AGM against MTRX-induced hepatotoxicity and its possible underlying mechanistic pathways. Mice were pre-treated with AGM (14\u2009mg/kg, orally) and administered a single injection of MTRX (20\u2009mg/kg, i.p.) on Day 6. MTRX-induced hepatic injury was evidenced by marked increase in serum hepatotoxicity markers, decreased hepatic reduced glutathione (GSH) level and superoxide dismutase (SOD) activity, and hepatic interleukin (IL)-10 content, besides increased levels of malondialdehyde (MDA), nitric oxide (NO), tumor necrosis factor-alpha (TNF-\u03b1), IL-6, c-Jun N-terminal kinase (JNK), BCL2-associated X protein (BAX), and Caspase-3. Moreover, MTRX increased hepatic expression of nuclear factor kappa-B (NF-\u03baB), and inducible nitric oxide synthase (iNOS), AGM pretreated group revealed a substantial elevation in hepatic antioxidant markers, besides marked reduction in the serum levels of hepatotoxicity markers and hepatic content of MDA, NO, NF-\u03baB, TNF-\u03b1, IL-6, iNOS, JNK, BAX, and Caspase-3. Furthermore, the protective effect of AGM was affirmed by liver histological examination. Therefore, AGM attenuates MTRX's liver injury by mitigating oxidative stress, inflammation, and apoptosis. These findings suggest that AGM could be considered as a potential adjuvant in MTRX-induced toxicity.",
"42406192": "ID: 42406192\nTitle: Dissecting PANoptosis in the Nervous System: A Unified Cell-Death Mechanism Driving Neuroimmune Activation and Chronic Neuroinflammation.\nAbstract: PANoptosis, a collective form of programmed cell death that includes apoptosis, necroptosis, and pyroptosis, is turning out to be a key player in the neuroimmune activation and sustaining chronic neuroinflammation in the nervous system. PANoptosis, in contrast to single cell death mechanisms, is a web of events coordinating neuronal death, glial cell changes, and inflammatory signals, being implicated in the initiation and progression of neurodegenerative and neuroinflammatory diseases. This review compiles current knowledge of the molecular pathways of PANoptotic signaling, its interaction with autophagy and immune pathways, and the in vivo models utilized for its pathogenic role in the central nervous system. We also tackle translational hurdles such as biomarker identification, therapeutic safety, disease, stage precision, and patient heterogeneity, which all point to the necessity of highly accurate interventions. Moreover, novel techniques combining systems biology, AI-based target identification, and personalized neuroimmunomodulation may effectively harness PANoptosis regulation to be both controlled and disease-specific. Through bridging the gap between the mechanistic insights and the translational perspectives, this review points out that PANoptosis provides a comprehensive basis for neuroimmune-associated pathology and represents a viable target for novel therapeutic approaches to counteract both chronic neuroinflammation and neurodegeneration.",
"42406382": "ID: 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.",
"42413719": "ID: 42413719\nTitle: Targeting PARP1-dependent parthanatos in Alzheimer's disease: Mechanisms and therapeutic opportunities.\nAbstract: Alzheimer's disease (AD) is the predominant cause of dementia globally. This review clarifies the dual function of poly(ADP-ribose) polymerase 1 (PARP1) in AD pathogenesis, emphasizing its role in mediating parthanatos, a unique caspase-independent cell death mechanism. We analyze contemporary literature regarding PARP1 expression, parthanatos signaling, and pharmaceutical treatments in AD models. In addition, PARP1 exhibits context-dependent duality: its physiological nuclear expression in hippocampus neurons is essential for memory consolidation and decreases early in cognitive impairment, suggesting a correlative association with synaptic malfunction. In contrast, overactivity of PARP1 resulting from A\u03b2-induced oxidative stress and DNA damage induces neurodegeneration via multiple pathways, including NAD+/ATP exhaustion leading to metabolism collapse, creation of the AIF-MIF complex promoting parthanatos, NF-\u03baB-induced neuroinflammation, dysregulation of mitophagy, and disruption of the neuroprotective SIRT1 signaling pathway. The overactivity contributes to a positive feedback loop, where PARP1 intensifies A\u03b2 and tau protein accumulation while simultaneously disrupting the BBB. In preclinical models of AD, genetic knockout, pharmacologic agents such as PJ34 and MC2050, or precursors of NAD+ such as nicotinamide and NMN attenuate A\u03b2 deposition, normalize metabolism, and ameliorate cognitive decline. The PARP1/parthanatos pathway is at the center of the confluence of oxidative stress, DNA damage, metabolism disorder, and neuroinflammation in AD. Metformin and other PARP1 inhibitors offer intriguing treatment options. PARP1's cell-type- and intracellular location-dependent activity necessitates careful consideration of context, dose, and disease stage while developing therapies. The present understanding in this review could inform future research on PARP1 regulation in AD clinical practice.",
"42414763": "ID: 42414763\nTitle: Atraric acid enhances neuronal survival and cognition against D-galactose-induced neurodegeneration via BDNF/TrkB/AKT signaling.\nAbstract: Aging-induced neurodegeneration is characterized by cognitive impairment, elevated oxidative stress, neuroinflammation, synaptic loss, and neuronal death. Atraric acid (AA), a phenolic compound obtained from lichens, is reported to have potent anti-inflammatory and antioxidant effects in various disease models. However, aging-induced cognitive impairment and dementia are still not elucidated. To fill this gap, we investigated AA (20\u00a0mg/kg/day, intraperitoneally (i.p.) for 4\u00a0weeks) against D-galactose (D-gal) (120\u00a0mg/kg/day, i.p. for 8\u00a0weeks)-induced brain senescence and memory dysfunction in mice. Behavioral tests, including NOR, MWM, and Y-maze, were conducted to assess cognitive function, followed by biochemical and immunofluorescence analyses. AA restored the BDNF/TrkB/Akt signaling axis disrupted by D-gal administration. Furthermore, immunoblotting for Nrf-2 and HO-1 revealed elevated expression in the mouse cortex and hippocampus. AA also enhanced antioxidant enzymes, including glutathione (GSH), glutathione S-transferase (GST), catalase (CAT), and superoxide dismutase (SOD), while reducing lipid peroxidation (LPO), thereby supporting its antioxidant role. Moreover, D-gal enhanced NF-kB-mediated neuroinflammation, apoptotic markers including caspase-3 and PARP-1, and suppressed synaptic proteins (SNAP-23 and PSD-95). Interestingly, these expression aberrations were reversed upon AA administration. Histological analyses using Nissl and Fluoro-Jade B staining further supported neuronal protection in the cortex and hippocampus. Collectively, these findings suggest that AA exerts neuroprotective effects against D-gal-induced aging and cognitive decline by reducing oxidative stress, neuroinflammation, neuronal apoptosis, and enhancing synaptic plasticity through BDNF/TrkB/Akt/CREB signaling.",
"42416408": "ID: 42416408\nTitle: The SGLT2i \"canagliflozin\" and the DPP-4i \"sitagliptin\" mitigate hypertensive nephropathy in adult male rats by modulating the Ang II/RAGE/Nox4/NLRP3 cascade.\nAbstract: Hypertensive nephropathy (HN) with progressive renal damage is a common consequence of arterial hypertension (HTN). This study addresses the renoprotective attributes of the sodium-glucose cotransporter-2 inhibitor canagliflozin (Cana) and the dipeptidyl peptidase-4 inhibitor sitagliptin (Sita) on HN. Twenty-four adult male Wistar rats were categorized into four groups (six per group): control (CTRL), hypertensive nephropathy (HN); rats were given L-NAME (50 mg/kg, i.p., once a day), HN + Cana; rats were given L-NAME injections alongside oral Cana 10 mg/kg, and HN + Sita; rats were provided Sita 10 mg/kg concurrently with L-NAME injection. All regimens were given once a day for five consecutive weeks. Various physiological, biochemical, molecular, and histological parameters were evaluated. Administration of Cana and Sita alleviated HN, as demonstrated by the notable improvements in renal functions, plasma angiotensin II, and systolic blood pressure. Additionally, a noticeable improvement in renal superoxide dismutase, malondialdehyde, NOD-like receptor family pyrin domain containing 3 inflammasome, interleukin (IL)-1\u03b2/-10, caspase 1, advanced glycation end products (AGEs), and relative expression of receptors for AGEs and nicotinamide adenine dinucleotide phosphate oxidase 4 was detected. Substantial enhancement in the microscopic structure of renal tissues, attenuated renal fibrosis, and decreased immunoreactivity of BAX and tumor necrosis factor-\u03b1 highlighted these protective attributes. Both Sita and Cana successfully attenuated HTN and subsequent HN, thereby restoring renal function; however, Sita's protective profile was more favorable. These results implied that Sita and Cana might provide renoprotective impacts for kidney damage triggered by HTN in rats. However, additional research to investigate their possible modes of action is necessary.",
"42416895": "ID: 42416895\nTitle: The Eight\u2011Chop Technique in Cataract Surgery: A Conceptual and Narrative Review of a Segmentation\u2011First Strategy.\nAbstract: To review the conceptual evolution, mechanical principles, and clinical performance of the Eight-Chop Technique and to clarify its role within contemporary cataract surgery. This narrative, concept\u2011driven review summarizes the historical development of nuclear fragmentation strategies, including sculpting-based techniques, divide-and-conquer, chop-based methods, femtosecond laser-assisted cataract surgery, and prechop techniques. A non\u2011systematic literature search of PubMed and Google Scholar was performed for articles published between 1991 and 2025 using combinations of the terms \"cataract\", \"phacoemulsification\", \"nuclear fragmentation\", \"phaco-chop\", \"prechop\", and \"eight-chop\". Adult human cataract surgery studies and key conceptual articles on nuclear segmentation and intraoperative fluidics were selectively included. Because most available clinical reports originate from the originating surgeon and closely affiliated groups, the evidence base is limited and heterogeneous, and formal systematic evidence synthesis was not attempted. Particular attention was directed toward the wedge-induced fracture mechanism, geometric optimization through eightfold nuclear division, and compatibility with modern fluidics systems. Published clinical studies together with the author's clinical experience were reviewed across a broad spectrum of cataract subtypes. In both standard cataracts and challenging conditions-including hard nuclear cataracts, white cataracts, small pupils, shallow anterior chamber, microcornea, diabetic eyes, and pseudoexfoliation syndrome-the Eight-Chop Technique has been reported to be associated with reduced phaco time, cumulative dissipated energy, and irrigation volume compared with conventional techniques. Corneal endothelial cell density loss was generally limited to approximately 0.9-6.7%, even in high-risk subgroups. Postoperative intraocular pressure also demonstrated sustained reduction during mid- to long-term follow-up. These findings are encouraging but preliminary and may partly reflect surgeon experience, case selection, and contemporary phacoemulsification platforms. The Eight\u2011Chop Technique is a segmentation\u2011first nuclear fragmentation strategy based on complete in\u2011the\u2011bag prefragmentation using a wedge\u2011induced fracture mechanism. Its conceptual compatibility with modern fluidics systems, including active fluidics platforms, may contribute to improved anterior chamber stability and a minimally invasive surgical profile. However, because current evidence is derived largely from single\u2011surgeon and closely affiliated studies, the clinical advantages of the Eight\u2011Chop Technique should be regarded as provisional. Independent, multicenter validation and randomized comparative trials are required before definitive conclusions can be drawn regarding its overall clinical superiority and generalizability.",
