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

Mitochondria play dual roles in ferroptosis by integrating metabolic activity, redox balance, and mitochondrial quality control; thereby influencing reactive oxygen species generation and lipid peroxidation. Lysosomes regulate ferroptotic sensitivity through iron mobilization, inter-organelle iron transfer, lysosomal redox activity/lipid peroxidation, lysosomal signaling hub, and ferritinophagy. The ER contributes to ferroptosis by coordinating lipid biosynthesis, membrane polyunsaturated fatty acid composition, and unfolded protein response signaling, as well as by disrupting antioxidant defenses and iron homeostasis, especially during ER stress.

            "abstract_text": "ID: 42524084\nTitle: Ferroptosis regulatory networks as therapeutic sensitizers in combination therapy for hepatocellular carcinoma (Review).\nAbstract: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, and multidrug resistance remains a major barrier to effective treatment. Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. The present narrative review summarizes current evidence on ferroptosis-mediated sensitization mechanisms in combination therapy for HCC, focusing on core regulatory networks, including glutathione peroxidase 4, System Xc- and iron metabolism pathways, and their interactions with key signaling pathways, such as activating transcription factor 4/signal transducer and activator of transcription 3, p53 and Wnt/\u03b2-catenin. The current review also discusses the synergistic effects and molecular mechanisms of ferroptosis inducers combined with targeted therapy, chemotherapy and immunotherapy. Furthermore, the potential value of ferroptosis-related biomarkers for predicting treatment response and prognosis is evaluated, and unresolved mechanistic questions and barriers to clinical translation are highlighted. Finally, the present review outlines future research directions, including the development of targeted nanodelivery systems and biomarker-based clinical trials, to support more precise ferroptosis-based combination strategies for HCC."

Previous studies have demonstrated an association between increased level of iron in the lung and aging and age-related lung diseases including pulmonary fibrosis and asthma in the elderly (AIE). However, the mechanisms underlying the accumulation of iron with aging or AIE, or the cell types involved, remain understudied. In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling."

In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling."

Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis, cholesterol and phospholipid remodeling that impacts membrane integrity and lipid rafts, lipid droplet-mediated buffering of metabolic stress, fatty acid oxidation-dependent energy supply, and sphingolipid-regulated apoptosis. This review delineates pre-existing tumor lipid programs from IR-induced adaptive responses, highlighting that their contributions to radiosensitivity or radioresistance are contingent upon tumor lineage, genetic background, microenvironmental conditions, and treatment context. The coupling of cancer cells with their microenvironment through lipid interactions, encompassing intercellular lipid transfer, nutrient competition, paracrine lipid mediators, and exosome-mediated signaling, is identified as a central component of radioresistance. In conclusion, therapeutic opportunities are evaluated based on their translational maturity, encompassing a spectrum from mechanistic concepts and preclinical radiosensitization strategies to approaches with emerging clinical significance. This synthesis, focused on radiotherapy, seeks to elucidate how lipid vulnerabilities can be strategically and judiciously exploited to enhance radiation outcomes."

Notably, this study identified that SYNCRIP expression is significantly elevated in glioblastoma (GBM) and is associated with poor prognosis and tumor progression. Mechanistically, SYNCRIP upregulates SIRT1 expression at both the transcriptional and post-transcriptional levels by stabilizing SIRT1 mRNA. Meanwhile, loss of SYNCRIP leads to reduced SIRT1 expression, accumulation of reactive oxygen species (ROS), and induction of ferroptosis. Notably, restoration of SIRT1 rescues cells from ferroptotic cell death, supporting the critical role of SIRT1 in SYNCRIP-mediated ferroptosis resistance. SYNCRIP also enhances hexokinase 2 (HK2) expression through transcriptional activation and internal ribosome entry site (IRES)-mediated translation, thereby promoting glycolytic activity in GBM. Furthermore, depletion of SYNCRIP results in mitochondrial dysfunction and impairs GBM cell migration and invasion by downregulating epithelial-mesenchymal transition (EMT)-associated factors.

Most transformed cells arrest, yet survive when deprived of the essential amino acid methionine. We instead find that EBV transformed lymphoblastoid cell lines (LCLs), which model the EBV latency III program-driven B-cell lymphoproliferative diseases of immunosuppressed hosts, rapidly die upon methionine restriction. Methionine restriction elevated LCL lipid reactive oxygen species and triggered ferroptosis. Whereas methionine restriction hypomethylates the EBV genome and triggers viral reactivation in latency I Burkitt cells by lowering the cellular methylation potential, the LCL latency III program instead redirected methionine toward redox defense, without altering the SAM/SAH ratio. Stable-isotope tracing revealed that latency III strongly induces transsulfuration, synthesizing cysteine de novo to support glutathione pools. The EBV oncoprotein LMP2A, which mimics B-cell receptor signaling, supported newly infected human B cell cystathionine-\u03b2-synthase and cystathionine-\u03b3-lyase expression and methionine dependence, phenocopied by immunoglobulin crosslinking.

ZDHHC palmitoyltransferases and depalmitoylating enzymes, including acyl-protein thioesterases and palmitoyl-protein thioesterase 1, constitute a dynamic circuitry that governs the localization, stability, and signaling competence of key regulators of tumor growth, metabolic adaptation, and immune phenotype. Here, we synthesize recent structural and chemical biology advances that clarify how human ZDHHC enzymes achieve acyl-chain recognition and substrate engagement. Structural studies show that these enzymes adopt a four-transmembrane, \"tent-like\" fold, in which the helices create a membrane-embedded cavity for acyl-chain accommodation. We also discuss how ankyrin-repeat domains and accessory partners shape substrate recruitment and subcellular localization, and we highlight emerging high-throughput platforms that enable quantitative profiling of isoform- and site-selective modulators. We then discuss how ZDHHC-substrate circuits rewire canonical growth-factor signaling and epithelial-mesenchymal transition programs, metabolic and ferroptotic control nodes, innate immune sensing, and chromatin-linked regulation. These convergent mechanisms position ZDHHC-mediated S-palmitoylation as a context-dependent regulator of tumor progression, therapy response, ferroptosis sensitivity, and immune phenotype. Finally, we outline a translational framework encompassing clinical-stage PPT1 inhibitors, selective ABHD17 blockade, emerging ZDHHC modulators, substrate-competitive strategies targeting checkpoint palmitoylation, and selected comparator approaches affecting Wnt and Hedgehog ligand lipidation. Current evidence positions ZDHHC-mediated S-palmitoylation as a regulatory layer with potential biomarker and therapeutic relevance; however, not all reported ZDHHC-substrate associations carry equivalent evidentiary weight. Mechanisms supported by convergent site-directed, genetic, biochemical, functional, and in vivo evidence should be distinguished from associations inferred mainly from expression profiling, overexpression systems, single-model observations, or broad pharmacological perturbation. Clinical translation remains preliminary and is constrained by isoform selectivity, substrate redundancy, incomplete pharmacodynamic read-outs, and the absence of validated biomarker-guided patient stratification."

Celastrol has recognized anti-inflammatory activity, but its mechanism in RA remains incompletely defined. This study investigated whether the anti-arthritic effect of celastrol is associated, at least in part, with a PTGS2-associated ferroptosis-resistance pathway in FLS. Potential targets of celastrol in RA were identified through integrated bioinformatic analyses. Collagen-induced arthritis (CIA) rats and primary FLS were used to evaluate the effects of celastrol in vivo and in vitro. Joint pathology, inflammatory mediator expression, oxidative stress, iron accumulation, lipid peroxidation, and ferroptosis-related proteins were assessed. Loss- and gain-of-function experiments were performed to examine the functional role of PTGS2. Bioinformatic screening identified PTGS2 as a candidate functional mediator linking celastrol to RA. In CIA rats, celastrol reduced paw swelling, arthritis severity, synovial hyperplasia, inflammatory cell infiltration, and cartilage and bone destruction. In FLS, celastrol suppressed cell proliferation and migration and decreased the expression of pro-inflammatory cytokines. Mechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment. PTGS2 expression was markedly elevated in RA models and was downregulated by celastrol. PTGS2 overexpression attenuated the anti-inflammatory effects of celastrol and reversed several ferroptosis-associated changes, supporting a functional role for PTGS2 in this process. Celastrol alleviates synovial inflammation and experimental arthritis, at least in part, in association with PTGS2 modulation and attenuation of a ferroptosis-resistant phenotype in FLS. To our knowledge, these findings provide experimental evidence linking celastrol, PTGS2-associated regulation, and ferroptosis resistance in RA models."

Reciprocally, MIRI exacerbates hypertension by inducing oxidative stress, inflammatory responses, cardiomyocyte death, fibrosis-associated myocardial remodeling, and RAAS system disruption, forming a vicious feedback cycle. This study aimed to investigate the regulatory role and underlying molecular mechanism of the lactate-related signaling axis in cardiomyocyte ferroptosis during MIRI, and to identify novel potential therapeutic targets for interrupting this detrimental feedback loop. In vivo mouse MIRI models, in vitro cardiomyocyte oxygen\u2012glucose deprivation/reoxygenation (OGD/R) models, and spontaneously hypertensive rat (SHR) models were successfully established. Oxaloacetate and \u03b2-alanine were administered to inhibit lactate production and protein lactylation, respectively. Hematoxylin\u2012eosin (HE) and Masson staining were performed to evaluate myocardial histopathological damage and fibrosis. Immunohistochemistry (IHC) and Western blotting were used to detect the protein expression levels of lysine lactylation (Kla), H3K18la, alanyl-tRNA synthetase 1 (AARS1), and acyl-CoA synthetase long-chain family member 4 (ACSL4). An enzyme-linked immunosorbent assay (ELISA) was adopted to quantify the lactate content and ferroptosis-related marker levels. Transmission electron microscopy (TEM), immunofluorescence staining, and chromatin immunoprecipitation (ChIP) assays were separately utilized to observe the mitochondrial ultrastructure, assess cellular lipid peroxidation, and verify gene promoter enrichment. Lactate, Kla, and H3K18la levels were markedly elevated in the MIRI and OGD/R models, accompanied by severe myocardial injury, fibrosis, and excessive cardiomyocyte ferroptosis. Inhibition of lactate production effectively reduced lactylation levels and mitigated ferroptosis as well as myocardial structural damage. Mechanistically, H3K18la was enriched in the promoter region of ACSL4 to facilitate its transcriptional activation, and knockdown of ACSL4 markedly reversed OGD/R-triggered cardiomyocyte ferroptosis. AARS1 overexpression strengthened lactylation and ACSL4 expression to promote ferroptosis, while its mutant did not. Notably, hypertension aggravated MIRI, promotes further increases in the level of histone lactylation mediated by AARS1, and exacerbates ferroptosis. Pharmacological intervention with \u03b2-alanine blocked the lactate/AARS1/H3K18la/ACSL4 axis and attenuated MIRI-induced myocardial damage. Abnormal lactate accumulation facilitates H3K18la modification via AARS1-dependent regulation, which transcriptionally activates ACSL4 and modulates cardiomyocyte ferroptosis, ultimately contributing to the pathological progression of MIRI. Targeting the lactate/AARS1/H3K18la/ACSL4 regulatory axis is a promising and viable therapeutic strategy for MIRI intervention."

However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures. Key findings were further evaluated using an external human SCI-related cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and published single-cell RNA-seq data. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. External validation in a human SCI-related peripheral blood cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and single-cell reanalysis further supported the upregulation of CD14 and its association with myeloid inflammatory activation and pyroptosis-, necroptosis-, and ferroptosis-related signatures. Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI."

Ferroptosis, an iron-dependent and lipid peroxidation-driven mechanism of regulated cell death, has been associated with neurodevelopment and neurodegeneration, prompting interest in its potential role in ASD. This narrative review consolidates from molecular and clinical studies, animal models, and in vitro systems to assess ferroptosis as a candidate mechanistic pathway, biomarker source, and therapeutic target in ASD. Peripheral transcriptomic analyses reveal differentially expressed ferroptosis-related genes, ferroptosis-based molecular clusters, and immune-activated subtype in children with ASD, facilitating the development of ferroptosis-derived diagnostic and scoring models with modest yet reproducible discrimination. Clinical data associate maladaptive polyunsaturated fatty acid profiles, increased lipid peroxidation products, and adverse docosahexaenoic acid/arachidonic acid ratio with autistic social impairments, aligning with ferroptosis-prone conditions. In rodent models, genetic or pharmacological modulation of DDIT4-PI3K/Akt signaling, Nrf2/GPX4/xCT antioxidant systems, and ferritinophagy mitigates ASD-like social deficits, repetitive behaviors, anxiety-like phenotypes, and liver pathology. Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways, indicating subtype-specific ferroptosis resistance. These findings suggest a complex, context-dependent role of ferroptosis and ferroptosis resistance in ASD, interacting with immune dysregulation, redox imbalance, and peripheral organ involvement.

Ferroptosis, an iron-dependent form of regulated cell death, has emerged as a promising therapeutic avenue. However, the role of Ribonucleotide Reductase M2 (RRM2) in ferroptosis regulation and its relevance to LUAD progression remain incompletely understood. We integrated bulk transcriptomic, proteomic, WGCNA, and single-cell datasets to evaluate the clinical and biological relevance of RRM2 in LUAD. Functional validation was performed using RRM2 knockdown, ferroptosis-inducer sensitivity assays, ferroptosis-related biochemical assays, NRF2/GPX4 pathway analysis, rescue experiments, and xenograft models. RRM2 was significantly upregulated in LUAD tissues and was associated with poor overall survival. Single-cell analysis localized high RRM2 expression to a proliferative tumor cell subpopulation enriched in cell cycle- and immune-related pathways. Functionally, RRM2 knockdown suppressed LUAD cell proliferation and tumor growth and was accompanied by increased ROS, lipid ROS, Fe\u00b2\u207a, and MDA levels and decreased GSH levels. RRM2 depletion also increased ferroptosis-inducer sensitivity, with enhanced erastin and RSL3 sensitivity in A549 cells and clear RSL3 sensitization in PC9 cells. In parallel, RRM2 silencing was associated with reduced NRF2 and GPX4 expression, decreased NRF2 nuclear-to-cytosolic signal intensity, and increased ACSL4 expression. NRF2 overexpression partially restored GPX4 immunofluorescence intensity in RRM2-knockdown cells. Moreover, NRF2 overexpression or Ferr-1 treatment partially reversed the growth-suppressive effects induced by RRM2 deficiency in vitro and in vivo. RRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis. These findings support RRM2 as a candidate prognostic biomarker and a potential therapeutic target in LUAD, while the precise molecular relationship between RRM2 and the NRF2/GPX4 axis warrants further investigation."

An understanding of the specific roles of macrophage subsets in lung tumor initiation and progression could promote new therapeutic approaches for this deadly disease. Here, we show that KRAS G12D mutations in lung epithelium drive proliferation of resident, embryonically-derived alveolar macrophages, which then promote tumor cell proliferation and protection from ferroptosis, leading to tumor progression. Using genetically engineered mouse models of mutant KRAS G12D non-small cell lung cancer 12,13 , we found that alveolar macrophages accumulate by proliferation in response to tumor cell-secreted IL-34, recapitulating events observed in late embryonic lung development. Tumor alveolar macrophages in turn drive IGF-1-dependent tumor cell proliferation. Neutralization or deletion of IL-34 suppresses IGF-1 expression, reduces macrophage and tumor cell proliferation and inhibits tumor progression. High IL34 and IGF1 correlate with poor survival in KRAS G12D/V lung adenocarcinomas and in other solid tumors, indicating that bi-directional proliferative signaling between resident macrophages and tumor cells can drive human lung tumor progression. These studies identify resident macrophage-tumor cell interactions as key interception points for lung cancer therapy."

Ferroptosis, an iron-dependent, non-apoptotic form of regulated cell death characterized by the lethal accumulation of lipid peroxides, represents a pharmacologically significant vulnerability in cancers that are resistant to apoptosis and tolerant to drugs. The resistance to ferroptosis, induced by the aberrant overexpression of the epigenetic enzyme histone deacetylases (HDACs) and the sustained transcriptional activity of key antiferroptotic targets, particularly GPX4 and SLC7A11, is enforced through epigenetic mechanisms. This review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways. These pathways include the transcriptional silencing of SLC7A11 and subsequent glutathione depletion, disruption of intracellular iron homeostasis via ferroportin downregulation, enhancement of mitochondrial ROS-induced lipid peroxidation, and suppression of the HDAC3-NRF2-GPX4 antiferroptotic axis. The specific roles of HDAC1, HDAC3, and HDAC10 in colorectal, lung, gastric, and hematological cancers are elucidated. Additionally, the review discusses hybrid molecules of HDAC-ferroptosis, combination strategies with GPX4 inhibitors, and immunochemotherapy. Considerations such as isoform selectivity, biomarker development, and clinical translation are addressed, highlighting HDAC inhibitor-mediated ferroptosis sensitization as a promising strategy to overcome drug resistance in cancer.

With mutant KRAS being a key driver, small molecule inhibitors targeting KRAS or pan-RAS (KRASi) have demonstrated exciting preclinical and early clinical anti-tumor efficacy, and the pan-RAS(ON) inhibitor daraxonrasib (RMC-6236) recently achieved Phase 3 clinically meaningful improvements in patient survival compared to chemotherapy. But resistance to RAS/KRAS inhibitor inevitably develops, which limits and compromises the treatment outcome. In this study, we investigated the combination of stereotactic body radiation therapy (SBRT) and KRAS inhibition (MRTX1133 and daraxonrasib) in the treatment of preclinical PDAC models. We found that this combination strategy synergistically suppresses PDAC cell growth in vitro and enhances tumor control while minimizing local recurrence in orthotopically implanted KPC ( LSL-Kras G12D/+ ;Trp53 R172H/+ ;Pdx1-Cre ) murine PDAC tumors in vivo . As radiation therapy (RT) induces ferroptosis in multiple cancer types and mutant KRAS promotes various anti-ferroptotic mechanisms, we tested the role of ferroptosis in promoting tumor-control efficacy. Intriguingly, the addition of a ferroptosis inhibitor, liproxstatin-1, to the combination therapy significantly abrogated the in vivo synergism between SBRT and KRAS inhibition, suggesting that treatment-induced ferroptosis at least partially drives the synergistic efficacy of this combination strategy. Our study indicates that this SBRT-KRASi combination has the potential to overcome treatment resistance and improve outcomes in PDAC patients. These data directly support the design of a planned multi-center Phase 2 clinical trial with this combination strategy in locally advanced PDAC."

However, its associated cardiotoxicity poses a major challenge for its therapeutic use. There are numerous studies exploring the underlying cellular mechanisms behind Dox-induced cardiotoxicity. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity. Under normal physiology, cardiomyocytes maintain a highly regulated iron homeostasis, while the polyunsaturated fatty acid-rich membrane also renders it susceptible to peroxidation, a hallmark of ferroptosis. Dox-induced cardiotoxicity disrupts the coordinated control of iron metabolism, generating reactive oxygen species, propagating lipid peroxidation, and impairing mitochondrial function. Progressive structural damage and functional loss of cardiomyocytes culminate in permanent cardiac cell death. Therefore, targeting regulatory nodes of ferroptosis may be beneficial for ameliorating Dox-induced cytotoxicity. However, it is still not clear whether the ferroptotic process merely acts as an initiator or can further act as an amplifier to upregulate the downstream signaling molecules in this cell death cascade. This review offers an overview of perspectives on the ferroptotic pathway and introduces readers to a novel driver-amplifier concept. See also the graphical abstract(Fig. 1)."

However, the precise mechanism underlying LCD action against hepatocellular carcinoma (HCC) remains unclear, particularly regarding its regulation of cell death. In this study, we comprehensively explored the effects of LCD on HCC cells in vitro and investigated its role and mechanism of action in the induction of PANoptosis. Our results reveal that LCD exhibited potent anti-HCC activities by decreasing cell viability and significantly inhibiting clonogenic survival in HCC cell lines. Our results demonstrate that LCD triggered a substantial accumulation of reactive oxygen species and induced depolarization of the mitochondrial membrane, leading to profound mitochondrial dysfunction. We further confirmed that LCD activated a comprehensive PANoptosis program by synchronously upregulating the expression of apoptotic proteins (Bax, c-CASP3, and c-PARP1), pyroptotic proteins (c-CASP 1 and c-GSDMD), and the phosphorylation of necroptotic executioners (p-MLKL and p-RIPK1). Treatment with the ROS inhibitor (NAC), apoptosis inhibitor (ZVAD), or necroptosis inhibitor (Nec-1) significantly reduced the expression of PANoptosis-related proteins in LCD-treated cells. Furthermore, molecular docking simulations and cellular thermal shift assay (CETSA) assay confirmed the direct and stable binding of LCD to PANoptosis-related proteins. In summary, we show for the first time that LCD exerts favorable anti-HCC activities via the induction of PANoptosis through a ROS-dependent mechanism and potntial direct modulation of core executive proteins. This multi-target action suggests that LCD could be a novel candidate for the management of hepatocellular carcinoma."

Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. The present narrative review summarizes current evidence on ferroptosis-mediated sensitization mechanisms in combination therapy for HCC, focusing on core regulatory networks, including glutathione peroxidase 4, System Xc- and iron metabolism pathways, and their interactions with key signaling pathways, such as activating transcription factor 4/signal transducer and activator of transcription 3, p53 and Wnt/\u03b2-catenin. The current review also discusses the synergistic effects and molecular mechanisms of ferroptosis inducers combined with targeted therapy, chemotherapy and immunotherapy. Furthermore, the potential value of ferroptosis-related biomarkers for predicting treatment response and prognosis is evaluated, and unresolved mechanistic questions and barriers to clinical translation are highlighted. Finally, the present review outlines future research directions, including the development of targeted nanodelivery systems and biomarker-based clinical trials, to support more precise ferroptosis-based combination strategies for HCC."

This review delineates pre-existing tumor lipid programs from IR-induced adaptive responses, highlighting that their contributions to radiosensitivity or radioresistance are contingent upon tumor lineage, genetic background, microenvironmental conditions, and treatment context. The coupling of cancer cells with their microenvironment through lipid interactions, encompassing intercellular lipid transfer, nutrient competition, paracrine lipid mediators, and exosome-mediated signaling, is identified as a central component of radioresistance. In conclusion, therapeutic opportunities are evaluated based on their translational maturity, encompassing a spectrum from mechanistic concepts and preclinical radiosensitization strategies to approaches with emerging clinical significance.

Notably, this study identified that SYNCRIP expression is significantly elevated in glioblastoma (GBM) and is associated with poor prognosis and tumor progression. Mechanistically, SYNCRIP upregulates SIRT1 expression at both the transcriptional and post-transcriptional levels by stabilizing SIRT1 mRNA. Meanwhile, loss of SYNCRIP leads to reduced SIRT1 expression, accumulation of reactive oxygen species (ROS), and induction of ferroptosis. Notably, restoration of SIRT1 rescues cells from ferroptotic cell death, supporting the critical role of SIRT1 in SYNCRIP-mediated ferroptosis resistance. SYNCRIP also enhances hexokinase 2 (HK2) expression through transcriptional activation and internal ribosome entry site (IRES)-mediated translation, thereby promoting glycolytic activity in GBM. Furthermore, depletion of SYNCRIP results in mitochondrial dysfunction and impairs GBM cell migration and invasion by downregulating epithelial-mesenchymal transition (EMT)-associated factors.

Most transformed cells arrest, yet survive when deprived of the essential amino acid methionine. We instead find that EBV transformed lymphoblastoid cell lines (LCLs), which model the EBV latency III program-driven B-cell lymphoproliferative diseases of immunosuppressed hosts, rapidly die upon methionine restriction. Methionine restriction elevated LCL lipid reactive oxygen species and triggered ferroptosis. Whereas methionine restriction hypomethylates the EBV genome and triggers viral reactivation in latency I Burkitt cells by lowering the cellular methylation potential, the LCL latency III program instead redirected methionine toward redox defense, without altering the SAM/SAH ratio. Stable-isotope tracing revealed that latency III strongly induces transsulfuration, synthesizing cysteine de novo to support glutathione pools. The EBV oncoprotein LMP2A, which mimics B-cell receptor signaling, supported newly infected human B cell cystathionine-\u03b2-synthase and cystathionine-\u03b3-lyase expression and methionine dependence, phenocopied by immunoglobulin crosslinking.

ZDHHC palmitoyltransferases and depalmitoylating enzymes, including acyl-protein thioesterases and palmitoyl-protein thioesterase 1, constitute a dynamic circuitry that governs the localization, stability, and signaling competence of key regulators of tumor growth, metabolic adaptation, and immune phenotype. Here, we synthesize recent structural and chemical biology advances that clarify how human ZDHHC enzymes achieve acyl-chain recognition and substrate engagement. Structural studies show that these enzymes adopt a four-transmembrane, \"tent-like\" fold, in which the helices create a membrane-embedded cavity for acyl-chain accommodation. We also discuss how ankyrin-repeat domains and accessory partners shape substrate recruitment and subcellular localization, and we highlight emerging high-throughput platforms that enable quantitative profiling of isoform- and site-selective modulators. We then discuss how ZDHHC-substrate circuits rewire canonical growth-factor signaling and epithelial-mesenchymal transition programs, metabolic and ferroptotic control nodes, innate immune sensing, and chromatin-linked regulation. These convergent mechanisms position ZDHHC-mediated S-palmitoylation as a context-dependent regulator of tumor progression, therapy response, ferroptosis sensitivity, and immune phenotype. Finally, we outline a translational framework encompassing clinical-stage PPT1 inhibitors, selective ABHD17 blockade, emerging ZDHHC modulators, substrate-competitive strategies targeting checkpoint palmitoylation, and selected comparator approaches affecting Wnt and Hedgehog ligand lipidation. Current evidence positions ZDHHC-mediated S-palmitoylation as a regulatory layer with potential biomarker and therapeutic relevance; however, not all reported ZDHHC-substrate associations carry equivalent evidentiary weight. Mechanisms supported by convergent site-directed, genetic, biochemical, functional, and in vivo evidence should be distinguished from associations inferred mainly from expression profiling, overexpression systems, single-model observations, or broad pharmacological perturbation. Clinical translation remains preliminary and is constrained by isoform selectivity, substrate redundancy, incomplete pharmacodynamic read-outs, and the absence of validated biomarker-guided patient stratification."

Celastrol has recognized anti-inflammatory activity, but its mechanism in RA remains incompletely defined. This study investigated whether the anti-arthritic effect of celastrol is associated, at least in part, with a PTGS2-associated ferroptosis-resistance pathway in FLS. Potential targets of celastrol in RA were identified through integrated bioinformatic analyses. Collagen-induced arthritis (CIA) rats and primary FLS were used to evaluate the effects of celastrol in vivo and in vitro. Joint pathology, inflammatory mediator expression, oxidative stress, iron accumulation, lipid peroxidation, and ferroptosis-related proteins were assessed. Loss- and gain-of-function experiments were performed to examine the functional role of PTGS2. Bioinformatic screening identified PTGS2 as a candidate functional mediator linking celastrol to RA. In CIA rats, celastrol reduced paw swelling, arthritis severity, synovial hyperplasia, inflammatory cell infiltration, and cartilage and bone destruction. In FLS, celastrol suppressed cell proliferation and migration and decreased the expression of pro-inflammatory cytokines. Mechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment. PTGS2 expression was markedly elevated in RA models and was downregulated by celastrol. PTGS2 overexpression attenuated the anti-inflammatory effects of celastrol and reversed several ferroptosis-associated changes, supporting a functional role for PTGS2 in this process. Celastrol alleviates synovial inflammation and experimental arthritis, at least in part, in association with PTGS2 modulation and attenuation of a ferroptosis-resistant phenotype in FLS. To our knowledge, these findings provide experimental evidence linking celastrol, PTGS2-associated regulation, and ferroptosis resistance in RA models."

Reciprocally, MIRI exacerbates hypertension by inducing oxidative stress, inflammatory responses, cardiomyocyte death, fibrosis-associated myocardial remodeling, and RAAS system disruption, forming a vicious feedback cycle. This study aimed to investigate the regulatory role and underlying molecular mechanism of the lactate-related signaling axis in cardiomyocyte ferroptosis during MIRI, and to identify novel potential therapeutic targets for interrupting this detrimental feedback loop. In vivo mouse MIRI models, in vitro cardiomyocyte oxygen\u2012glucose deprivation/reoxygenation (OGD/R) models, and spontaneously hypertensive rat (SHR) models were successfully established. Oxaloacetate and \u03b2-alanine were administered to inhibit lactate production and protein lactylation, respectively. Hematoxylin\u2012eosin (HE) and Masson staining were performed to evaluate myocardial histopathological damage and fibrosis. Immunohistochemistry (IHC) and Western blotting were used to detect the protein expression levels of lysine lactylation (Kla), H3K18la, alanyl-tRNA synthetase 1 (AARS1), and acyl-CoA synthetase long-chain family member 4 (ACSL4). An enzyme-linked immunosorbent assay (ELISA) was adopted to quantify the lactate content and ferroptosis-related marker levels. Transmission electron microscopy (TEM), immunofluorescence staining, and chromatin immunoprecipitation (ChIP) assays were separately utilized to observe the mitochondrial ultrastructure, assess cellular lipid peroxidation, and verify gene promoter enrichment. Lactate, Kla, and H3K18la levels were markedly elevated in the MIRI and OGD/R models, accompanied by severe myocardial injury, fibrosis, and excessive cardiomyocyte ferroptosis. Inhibition of lactate production effectively reduced lactylation levels and mitigated ferroptosis as well as myocardial structural damage. Mechanistically, H3K18la was enriched in the promoter region of ACSL4 to facilitate its transcriptional activation, and knockdown of ACSL4 markedly reversed OGD/R-triggered cardiomyocyte ferroptosis. AARS1 overexpression strengthened lactylation and ACSL4 expression to promote ferroptosis, while its mutant did not. Notably, hypertension aggravated MIRI, promotes further increases in the level of histone lactylation mediated by AARS1, and exacerbates ferroptosis. Pharmacological intervention with \u03b2-alanine blocked the lactate/AARS1/H3K18la/ACSL4 axis and attenuated MIRI-induced myocardial damage. Abnormal lactate accumulation facilitates H3K18la modification via AARS1-dependent regulation, which transcriptionally activates ACSL4 and modulates cardiomyocyte ferroptosis, ultimately contributing to the pathological progression of MIRI. Targeting the lactate/AARS1/H3K18la/ACSL4 regulatory axis is a promising and viable therapeutic strategy for MIRI intervention."

However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures.

Pyroptosis, an inflammatory form of programmed cell death triggered by inflammasome activation, plays a critical role in various CVDs, including hypertension, ischemia\u2011reperfusion injury (I/R injury), atherosclerosis, and heart failure (HF). Despite rapid growth of the literature, no bibliometric analysis has specifically focused on this area. Data were retrieved from the Web of Science Core Collection (1998-April 27, 2025). Bibliometric and visual analyses were performed using CiteSpace and VOSviewer to examine publication trends, country/region, funding agency, institution, author, journal, subject category, co\u2011cited reference, keyword co\u2011occurrence, and emerging hotspots. A total of 4,511 documents (2,918 original articles and 1,593 reviews) were included. China contributed 2,259 publications (50.1% of total) with 56,326 citations; the United States contributed 1,022 publications (22.7%) with 79,057 citations and the highest country\u2011level h\u2011index (147); and Italy ranked third with 290 publications (6.4%). Harvard University and its affiliated institutions led in both publication quantity and impact (h\u2011index, citations per article).

Recent bursts (2024\u20112025) highlight \"pyroptosis\" and \"ferroptosis\" as emerging frontiers. This bibliometric study identifies NLRP3 as the central research focus in inflammasome\u2011driven pyroptosis research, with the strongest citation burst. The findings reveal a shift from basic mechanistic studies toward translational research, highlighting emerging priorities such as the crosstalk between pyroptosis and ferroptosis and the need for patient stratification in future clinical trials."

Ferroptosis, an iron-dependent and lipid peroxidation-driven mechanism of regulated cell death, has been associated with neurodevelopment and neurodegeneration, prompting interest in its potential role in ASD. This narrative review consolidates from molecular and clinical studies, animal models, and in vitro systems to assess ferroptosis as a candidate mechanistic pathway, biomarker source, and therapeutic target in ASD. Peripheral transcriptomic analyses reveal differentially expressed ferroptosis-related genes, ferroptosis-based molecular clusters, and immune-activated subtype in children with ASD, facilitating the development of ferroptosis-derived diagnostic and scoring models with modest yet reproducible discrimination. Clinical data associate maladaptive polyunsaturated fatty acid profiles, increased lipid peroxidation products, and adverse docosahexaenoic acid/arachidonic acid ratio with autistic social impairments, aligning with ferroptosis-prone conditions. In rodent models, genetic or pharmacological modulation of DDIT4-PI3K/Akt signaling, Nrf2/GPX4/xCT antioxidant systems, and ferritinophagy mitigates ASD-like social deficits, repetitive behaviors, anxiety-like phenotypes, and liver pathology. Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways, indicating subtype-specific ferroptosis resistance. These findings suggest a complex, context-dependent role of ferroptosis and ferroptosis resistance in ASD, interacting with immune dysregulation, redox imbalance, and peripheral organ involvement. Nevertheless, longitudinal and interventional studies integrating brain, peripheral, and cellular data are required to establish causality, define meaningful ferroptosis-related signatures, and evaluate the safety and efficacy of ferroptosis-modulating interventions."

Ferroptosis, an iron-dependent form of regulated cell death, has emerged as a promising therapeutic avenue. However, the role of Ribonucleotide Reductase M2 (RRM2) in ferroptosis regulation and its relevance to LUAD progression remain incompletely understood. We integrated bulk transcriptomic, proteomic, WGCNA, and single-cell datasets to evaluate the clinical and biological relevance of RRM2 in LUAD. Functional validation was performed using RRM2 knockdown, ferroptosis-inducer sensitivity assays, ferroptosis-related biochemical assays, NRF2/GPX4 pathway analysis, rescue experiments, and xenograft models. RRM2 was significantly upregulated in LUAD tissues and was associated with poor overall survival. Single-cell analysis localized high RRM2 expression to a proliferative tumor cell subpopulation enriched in cell cycle- and immune-related pathways. Functionally, RRM2 knockdown suppressed LUAD cell proliferation and tumor growth and was accompanied by increased ROS, lipid ROS, Fe\u00b2\u207a, and MDA levels and decreased GSH levels. RRM2 depletion also increased ferroptosis-inducer sensitivity, with enhanced erastin and RSL3 sensitivity in A549 cells and clear RSL3 sensitization in PC9 cells. In parallel, RRM2 silencing was associated with reduced NRF2 and GPX4 expression, decreased NRF2 nuclear-to-cytosolic signal intensity, and increased ACSL4 expression. NRF2 overexpression partially restored GPX4 immunofluorescence intensity in RRM2-knockdown cells. Moreover, NRF2 overexpression or Ferr-1 treatment partially reversed the growth-suppressive effects induced by RRM2 deficiency in vitro and in vivo. RRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis. These findings support RRM2 as a candidate prognostic biomarker and a potential therapeutic target in LUAD, while the precise molecular relationship between RRM2 and the NRF2/GPX4 axis warrants further investigation."

An understanding of the specific roles of macrophage subsets in lung tumor initiation and progression could promote new therapeutic approaches for this deadly disease. Here, we show that KRAS G12D mutations in lung epithelium drive proliferation of resident, embryonically-derived alveolar macrophages, which then promote tumor cell proliferation and protection from ferroptosis, leading to tumor progression. Using genetically engineered mouse models of mutant KRAS G12D non-small cell lung cancer 12,13 , we found that alveolar macrophages accumulate by proliferation in response to tumor cell-secreted IL-34, recapitulating events observed in late embryonic lung development. Tumor alveolar macrophages in turn drive IGF-1-dependent tumor cell proliferation. Neutralization or deletion of IL-34 suppresses IGF-1 expression, reduces macrophage and tumor cell proliferation and inhibits tumor progression. High IL34 and IGF1 correlate with poor survival in KRAS G12D/V lung adenocarcinomas and in other solid tumors, indicating that bi-directional proliferative signaling between resident macrophages and tumor cells can drive human lung tumor progression. These studies identify resident macrophage-tumor cell interactions as key interception points for lung cancer therapy."

Ferroptosis, an iron-dependent, non-apoptotic form of regulated cell death characterized by the lethal accumulation of lipid peroxides, represents a pharmacologically significant vulnerability in cancers that are resistant to apoptosis and tolerant to drugs. The resistance to ferroptosis, induced by the aberrant overexpression of the epigenetic enzyme histone deacetylases (HDACs) and the sustained transcriptional activity of key antiferroptotic targets, particularly GPX4 and SLC7A11, is enforced through epigenetic mechanisms. This review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways. These pathways include the transcriptional silencing of SLC7A11 and subsequent glutathione depletion, disruption of intracellular iron homeostasis via ferroportin downregulation, enhancement of mitochondrial ROS-induced lipid peroxidation, and suppression of the HDAC3-NRF2-GPX4 antiferroptotic axis. The specific roles of HDAC1, HDAC3, and HDAC10 in colorectal, lung, gastric, and hematological cancers are elucidated. Additionally, the review discusses hybrid molecules of HDAC-ferroptosis, combination strategies with GPX4 inhibitors, and immunochemotherapy. Considerations such as isoform selectivity, biomarker development, and clinical translation are addressed, highlighting HDAC inhibitor-mediated ferroptosis sensitization as a promising strategy to overcome drug resistance in cancer.

With mutant KRAS being a key driver, small molecule inhibitors targeting KRAS or pan-RAS (KRASi) have demonstrated exciting preclinical and early clinical anti-tumor efficacy, and the pan-RAS(ON) inhibitor daraxonrasib (RMC-6236) recently achieved Phase 3 clinically meaningful improvements in patient survival compared to chemotherapy. But resistance to RAS/KRAS inhibitor inevitably develops, which limits and compromises the treatment outcome. In this study, we investigated the combination of stereotactic body radiation therapy (SBRT) and KRAS inhibition (MRTX1133 and daraxonrasib) in the treatment of preclinical PDAC models. We found that this combination strategy synergistically suppresses PDAC cell growth in vitro and enhances tumor control while minimizing local recurrence in orthotopically implanted KPC ( LSL-Kras G12D/+ ;Trp53 R172H/+ ;Pdx1-Cre ) murine PDAC tumors in vivo . As radiation therapy (RT) induces ferroptosis in multiple cancer types and mutant KRAS promotes various anti-ferroptotic mechanisms, we tested the role of ferroptosis in promoting tumor-control efficacy. Intriguingly, the addition of a ferroptosis inhibitor, liproxstatin-1, to the combination therapy significantly abrogated the in vivo synergism between SBRT and KRAS inhibition, suggesting that treatment-induced ferroptosis at least partially drives the synergistic efficacy of this combination strategy. Our study indicates that this SBRT-KRASi combination has the potential to overcome treatment resistance and improve outcomes in PDAC patients. These data directly support the design of a planned multi-center Phase 2 clinical trial with this combination strategy in locally advanced PDAC."

However, its associated cardiotoxicity poses a major challenge for its therapeutic use. There are numerous studies exploring the underlying cellular mechanisms behind Dox-induced cardiotoxicity. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity. Under normal physiology, cardiomyocytes maintain a highly regulated iron homeostasis, while the polyunsaturated fatty acid-rich membrane also renders it susceptible to peroxidation, a hallmark of ferroptosis. Dox-induced cardiotoxicity disrupts the coordinated control of iron metabolism, generating reactive oxygen species, propagating lipid peroxidation, and impairing mitochondrial function. Progressive structural damage and functional loss of cardiomyocytes culminate in permanent cardiac cell death. Therefore, targeting regulatory nodes of ferroptosis may be beneficial for ameliorating Dox-induced cytotoxicity. However, it is still not clear whether the ferroptotic process merely acts as an initiator or can further act as an amplifier to upregulate the downstream signaling molecules in this cell death cascade. This review offers an overview of perspectives on the ferroptotic pathway and introduces readers to a novel driver-amplifier concept. See also the graphical abstract(Fig. 1)."

However, the precise mechanism underlying LCD action against hepatocellular carcinoma (HCC) remains unclear, particularly regarding its regulation of cell death. In this study, we comprehensively explored the effects of LCD on HCC cells in vitro and investigated its role and mechanism of action in the induction of PANoptosis. Our results reveal that LCD exhibited potent anti-HCC activities by decreasing cell viability and significantly inhibiting clonogenic survival in HCC cell lines. Our results demonstrate that LCD triggered a substantial accumulation of reactive oxygen species and induced depolarization of the mitochondrial membrane, leading to profound mitochondrial dysfunction. We further confirmed that LCD activated a comprehensive PANoptosis program by synchronously upregulating the expression of apoptotic proteins (Bax, c-CASP3, and c-PARP1), pyroptotic proteins (c-CASP 1 and c-GSDMD), and the phosphorylation of necroptotic executioners (p-MLKL and p-RIPK1). Treatment with the ROS inhibitor (NAC), apoptosis inhibitor (ZVAD), or necroptosis inhibitor (Nec-1) significantly reduced the expression of PANoptosis-related proteins in LCD-treated cells. Furthermore, molecular docking simulations and cellular thermal shift assay (CETSA) assay confirmed the direct and stable binding of LCD to PANoptosis-related proteins. In summary, we show for the first time that LCD exerts favorable anti-HCC activities via the induction of PANoptosis through a ROS-dependent mechanism and potntial direct modulation of core executive proteins. This multi-target action suggests that LCD could be a novel candidate for the management of hepatocellular carcinoma."

Rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation. In this review, we summarize the molecular mechanisms by which microglial ferroptosis mediates neuroinflammatory responses, with a focus on iron homeostasis disruption, lipid peroxidation and ROS amplification, collapse of the GPX4-dependent antioxidant defense, mitochondrial ROS generation, and inflammasome activation. We further classify related CNS diseases into three categories according to disease course and pathological features: chronic neurodegenerative and demyelinating diseases, acute CNS injuries, and neuropsychiatric or systemic inflammation-related brain dysfunction. Within this framework, we compare the pathological significance of microglial ferroptosis across different disease contexts. We also discuss potential therapeutic strategies targeting iron homeostasis, lipid peroxidation, antioxidant defenses, inflammatory amplification networks, and microglia-specific delivery systems. Finally, we address current challenges in the field, including insufficient cell-type specificity, inconsistent detection criteria, disease-stage heterogeneity, and barriers to clinical translation. This review provides an integrated perspective on the mechanisms by which microglial ferroptosis drives neuroinflammation and highlights its potential relevance for precision intervention in CNS diseases."

This study aimed to investigate the role of ferroptosis in CA-induced spinal cord injury and to evaluate the neuroprotective effects of edaravone. Asphyxial CA was induced in rats for 5\u202fmin, followed by resuscitation. Edaravone was administered immediately after the return of spontaneous circulation (ROSC). At 24\u202fh post-ROSC, The CA group exhibited significant hindlimb motor deficits and reduced survival rates. Histological analysis revealed selective injury of choline acetyltransferase (ChAT)-positive motor neurons in the lumbar spinal cord, accompanied by mitochondrial shrinkage and membrane rupture, which are characteristic of ferroptosis. Immunofluorescence demonstrated a selective upregulation of the pro-ferroptotic enzyme acyl-CoA synthetase long-chain family member 4 (ACSL4) specifically in ChAT-positive motor neurons, whereas glutathione peroxidase 4 (GPX4) expression remained relatively preserved. Edaravone treatment significantly improved neurological outcomes and survival, attenuated lipid peroxidation (evidenced by decreased malondialdehyde and preserved glutathione levels), and effectively suppressed ACSL4 upregulation in the motor neurons. Furthermore, edaravone mitigated neuroinflammation by reducing astrogliosis and microglial activation. These findings provide the first evidence that ACSL4-mediated ferroptosis is a key driver of acute spinal motor neuron injury following CA. Edaravone exerts potent neuroprotection by targeting this pathway, suggesting its therapeutic potential for ameliorating spinal cord injury in patients with CA."

However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse."

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma."

PANoptosis is a newly identified cell death mode that synergistically initiates pyroptosis, apoptosis and necroptosis via activation of PANoptosome. It is closely associated with oxidative stress, neuroinflammation, and secondary injury following TBI and SCI, yet the key pathogenic factors and mechanisms underlying PANoptosis remain incompletely elucidated. Mitochondria, as a central organelle for energy synthesis and oxidative stress, its health and homeostasis are the cornerstone of cell survival and biological function. Emerging evidence suggests that the loss of mitochondrial homeostasis plays a fundamental role in the activation and execution of PANoptosis across various cell types. Here, we review the detailed manifestations of mitochondrial homeostasis imbalance in TBI and SCI, such as impaired biogenesis, abnormal dynamics, mitophagy dysfunction, and mitochondria-derived vesicles. Meanwhile, we systematically analyze the characteristics and pathological effects of PANoptosis cascade following TBI and SCI, with a focus on the regulatory patterns, mechanisms, and potential targets of injured mitochondria driving PANoptosis. In addition, we discuss the advancements and future perspectives of mitochondria-based strategies for modulating PANoptosis in TBI and SCI. Taken together, despite considerable challenges in governing post-traumatic mitochondria homeostasis, its multiple targeting of the upstream PANoptosome and downstream cell death signaling offers a promising approach to improve the outcome of CNS trauma."

This study aims to investigate the regulatory role of anti-HMGB1 antibody in the depressive-like behaviour of D-SCI rats and to explore its underlying mechanisms. A depression model was established in rats 5\u2009weeks after SCI. The expression of HMGB1 and ferroptosis markers (MDA, GSH and iron ion deposition) in the hippocampus were examined in both the sham group and the D-SCI group. Subsequently, D-SCI rats were treated with an anti-HMGB1 antibody, and the depression-like behaviours of each group were assessed using open field and sucrose preference tests. Ferroptosis levels in the hippocampus, as well as the expression of ferroptosis-related proteins (ACSL4, SLC7A11 and GPX4), were also investigated. The co-localization of HMGB1 and NeuN in the rat hippocampus was detected by immunofluorescence double staining. Furthermore, at the cellular level, the effect of the anti-HMGB1 antibody on Erastin-induced ferroptosis in rat hippocampal neurons was analysed. The results indicated that compared to the sham group, the levels of HMGB1 and ferroptosis in the hippocampus of rats in the D-SCI group were significantly elevated. Administering anti-HMGB1 antibody to D-SCI rats could significantly augment their activity distance, movement speed and sucrose preference rate, while also suppressing the ferroptosis level and the expression of ferroptosis-related proteins in the hippocampus. Moreover, HMGB1 and NeuN were co-expressed in the rat hippocampus. The results from primary rat hippocampal neurons indicated that anti-HMGB1 antibody could inhibit erastin-induced ferroptosis in rat hippocampal neurons. Taken together, anti-HMGB1 antibody therapy can ameliorate depressive behaviour in D-SCI rats; the possible mechanism may involve the inhibition of ferroptosis in hippocampal neurons."

We investigated the role of sphingosine-1-phosphate receptor 2 (S1P2 receptor) in contusive spinal cord injury and evaluated the therapeutic effects of an S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) in a rat model of SCI. The SCI model was established using a 10\u2009g weight dropped onto the T10 vertebrae in female rats. After functional testing, spinal cords were harvested for biochemical and histopathological assays at different time points. Nissl and Prussian blue staining were used to analyse neuronal death. Neuronal ferroptosis in spinal cords was examined using transmission electron microscopy, and lipid peroxidation in the cultured neurones was analysed. After SCI, S1P (Sphingosine 1-phosphate) was released from crushed spinal cords and subsequently activated the neuronal S1P2 receptor to increase lipid peroxidation, which injured neurones via inducing neuronal ferroptosis through the P-ERK/ERK/ACSL4 pathway, resulting in limb paralysis. S1P2 receptor inhibition significantly blocked S1P2 receptor activation and attenuated neuronal ferroptosis. Thus, S1P2 receptor was a therapeutic target for the treatment of SCI. Systemic administration of the S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) effectively promoted locomotor function recovery by attenuating neuronal ferroptosis in rat spinal cords. S118 impeded neuronal ferroptosis by inhibiting lipid peroxidation. Contusive SCI is characterised by neuronal loss due to S1P2 receptor activation in spinal neurones. S1P2 receptor activation increases lipid peroxidation, which induces neuronal ferroptosis.

Primary microglia cells were extracted from neonatal 1-2 days C57BL/6 mice and divided into control group, Yoda1 (Piezo1 agonist) group, and Yoda1+GsMTx4 (Piezo1 inhibitor) group. Live/dead cell staining, reactive oxygen species (ROS) fluorescence staining, 5, 5', 6, 6'-tetrachloro-1, 1', 3, 3'-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) mitochondrial membrane potential detection, and transmission electron microscopy were utilized to assess microglial ferroptosis and mitochondrial functional characteristics. SPF female C57BL/6 mice aged 6 to 8 weeks were used to detect the expression of Piezo1 at different time points after SCI by Western blot, and the two time points with no significant change and the most significant change in Piezo1 expression after SCI were selected for subsequent experiments. T 8, T 9 SCI models were established by modified Allen's method, and were divided into sham operation group, injury group, and injury+shPiezo1 group (Piezo1-targeted interfering virus AAV-shPiezo1 was injected in situ to knock down the expression of Piezo1 14 days before modeling). Colocalization of Piezo1 with microglial markers purinergic receptor P2Y12 (P2ry12), and the expressions of glutathione peroxidase 4 (GPX4) and acyl coenzyme A synthetase long chain member 4 (ACSL4) were observed by immunofluorescence staining. Basso Mouse Scale (BMS) score was used to assess hindlimb motor function in mice. The level of ROS was detected by dihydroethidium (DHE) staining; the content of malondialdehyde (MDA) was detected by MDA kit; the levels of tumor necrosis factor \u03b1 (TNF-\u03b1) and interleukin 10 (IL-10) were detected by ELISA assay; the pathological morphology of spinal cord was observed by HE staining. In vitro experiments showed that compared with the control group, the Yoda1 group had typical ultrastructural changes of ferroptosis, such as increased microglial cell death, enhanced ROS fluorescence, mitochondrial membrane potential depolarization, mitochondrial shrinkage and mitochondrial cristae breakage (all P<0.05), while the GsMTx4 group could partially reverse the above effects ( P<0.05). In vivo experiments demonstrated that the expression of Piezo1 in spinal cord tissue was up-regulated sequentially after SCI, and reached the peak on the 7th day after SCI ( P<0.05), and it was mainly localized in P2ry12-positive microglia. Compared with the injury group, in the injury+shPiezo1 group, the expression of ferroptosis core protein GPX4 in microglia was increased, the expression of ACSL4 was decreased, the levels of ROS and MDA in spinal cord tissue were decreased ( P<0.05), the level of pro-inflammatory factor TNF-\u03b1 was decreased, and the level of anti-inflammatory factor IL-10 was increased ( P<0.05). In addition, the BMS score was significantly higher than that of the injury group ( P<0.05) from the 14th day after operation, and the spinal cord tissue structure was relatively well preserved, and the cavity area was reduced. SCI activates the Piezo1 channel in microglia, triggering mitochondrial dysfunction and mediating cellular ferroptosis, thereby aggravating secondary neuroinflammation. Targeted inhibition of Piezo1 effectively blocks the ferroptosis process, ameliorates the immune microenvironment, and promotes tissue repair and locomotor functional recovery after SCI. \u63a2\u7a76\u673a\u68b0\u654f\u611f\u6027\u79bb\u5b50\u901a\u9053Piezo1\u5728\u810a\u9ad3\u635f\u4f24\uff08spinal cord injury\uff0cSCI\uff09\u540e\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u4e2d\u7684\u4f5c\u7528\u673a\u5236\uff0c\u5e76\u8bc4\u4f30\u6291\u5236Piezo1\u5bf9\u6539\u5584\u635f\u4f24\u5fae\u73af\u5883\u53ca\u4fc3\u8fdb\u795e\u7ecf\u529f\u80fd\u6062\u590d\u7684\u5f71\u54cd\u3002. \u63d0\u53d6\u65b0\u751f1\uff5e2 d C57BL/6\u5c0f\u9f20\u539f\u4ee3\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001Yoda1\uff08Piezo1\u6fc0\u52a8\u5242\uff09\u7ec4\u53caYoda1+GsMTx4\uff08Piezo1\u6291\u5236\u5242\uff09\u7ec4\u3002\u5229\u7528\u6d3b\u6b7b\u7ec6\u80de\u67d3\u8272\u3001\u6d3b\u6027\u6c27\uff08reactive oxygen species\uff0cROS\uff09\u8367\u5149\u67d3\u8272\u30015\uff0c5\u2019\uff0c6\uff0c6\u2019-\u56db\u6c2f-1\uff0c1\u2019\uff0c3\uff0c3\u2019-\u56db\u4e59\u57fa\u82ef\u5e76\u54aa\u5511\u78b3\u82b1\u9752\u7898\u5316\u7269\uff085\uff0c5\u2019\uff0c6\uff0c6\u2019-tetrachloro-1\uff0c1\u2019\uff0c3\uff0c3\u2019-tetraethylbenzimidazolylcarbocyanine iodide\uff0cJC-1\uff09\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u68c0\u6d4b\u53ca\u900f\u5c04\u7535\u955c\u89c2\u5bdf\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u53ca\u7ebf\u7c92\u4f53\u529f\u80fd\u7279\u5f81\u3002\u53d66\uff5e8\u5468\u9f84SPF\u7ea7\u96cc\u6027C57BL/6\u5c0f\u9f20\uff0c\u91c7\u7528Western blot\u68c0\u6d4bPiezo1\u5728SCI\u540e\u4e0d\u540c\u65f6\u95f4\u70b9\u7684\u8868\u8fbe\u89c4\u5f8b\uff0c\u9009\u53d6\u635f\u4f24\u540ePiezo1\u8868\u8fbe\u672a\u89c1\u660e\u663e\u6539\u53d8\u53ca\u53d8\u5316\u6700\u663e\u8457\u76842\u4e2a\u65f6\u95f4\u70b9\u8fdb\u884c\u540e\u7eed\u5b9e\u9a8c\u3002\u91c7\u7528\u6539\u826fAllen\u6cd5\u5236\u5907T 8\u3001T 9 SCI\u6a21\u578b\uff1b\u5b9e\u9a8c\u5206\u4e3a\u5047\u624b\u672f\u7ec4\u3001\u635f\u4f24\u7ec4\u548c\u635f\u4f24+shPiezo1\u7ec4\uff08\u9020\u6a21\u524d14 d\u539f\u4f4d\u6ce8\u5c04\u9776\u5411Piezo1\u7684\u5e72\u6270\u75c5\u6bd2AAV-shPiezo1\u4ee5\u6572\u4f4ePiezo1\u8868\u8fbe\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u89c2\u5bdfPiezo1\u4e0e\u5c0f\u80f6\u8d28\u7ec6\u80de\u6807\u5fd7\u7269\u560c\u5464\u80fd\u53d7\u4f53P2Y12\uff08purinergic receptor P2Y12\uff0cP2ry12\uff09\u7684\u5171\u5b9a\u4f4d\u53ca\u8c37\u80f1\u7518\u80bd\u8fc7\u6c27\u5316\u7269\u91764\uff08glutathione peroxidase 4\uff0cGPX4\uff09\u3001\u9170\u57fa\u8f85\u9176A\u5408\u6210\u9176\u957f\u94fe\u5bb6\u65cf\u6210\u54584\uff08acyl coenzyme A synthetase long chain member 4\uff0cACSL4\uff09\u7684\u8868\u8fbe\uff1bBasso Mouse Scale\uff08BMS\uff09\u8bc4\u5206\u8bc4\u4f30\u5c0f\u9f20\u540e\u80a2\u8fd0\u52a8\u529f\u80fd\uff1b\u4e8c\u6c22\u4e59\u952d\uff08dihydroethidium\uff0cDHE\uff09\u67d3\u8272\u68c0\u6d4b\u7ec4\u7ec7ROS\u6c34\u5e73\uff1b\u4e19\u4e8c\u919b\uff08malondialdehyde\uff0cMDA\uff09\u8bd5\u5242\u76d2\u68c0\u6d4bMDA\u542b\u91cf\uff1bELISA\u68c0\u6d4b\u708e\u75c7\u56e0\u5b50TNF-\u03b1\u3001IL-10\u6c34\u5e73\uff1bHE\u67d3\u8272\u89c2\u5bdf\u810a\u9ad3\u7ec4\u7ec7\u75c5\u7406\u5f62\u6001\u3002. \u4f53\u5916\u5b9e\u9a8c\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cYoda1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u6b7b\u4ea1\u589e\u591a\u3001ROS\u8367\u5149\u589e\u5f3a\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u53bb\u6781\u5316\u3001\u7ebf\u7c92\u4f53\u51fa\u73b0\u76b1\u7f29\u53ca\u5d74\u65ad\u88c2\u7b49\u94c1\u6b7b\u4ea1\u5178\u578b\u8d85\u5fae\u7ed3\u6784\u6539\u53d8\uff08\u5747 P<0.05\uff09\uff1b\u800cGsMTx4\u7ec4\u53ef\u90e8\u5206\u9006\u8f6c\u4e0a\u8ff0\u6548\u5e94\uff08 P<0.05\uff09\u3002\u4f53\u5185\u5b9e\u9a8c\u793a\uff0cSCI\u540e\u810a\u9ad3\u7ec4\u7ec7\u4e2dPiezo1\u8868\u8fbe\u5448\u65f6\u5e8f\u6027\u4e0a\u8c03\uff0c\u672f\u540e7 d\u8fbe\u5cf0\u503c\uff08 P<0.05\uff09\uff0c\u4e14\u4e3b\u8981\u5b9a\u4f4d\u4e8eP2ry12\u9633\u6027\u5c0f\u80f6\u8d28\u7ec6\u80de\u3002\u4e0e\u635f\u4f24\u7ec4\u6bd4\u8f83\uff0c\u635f\u4f24+shPiezo1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u5185\u94c1\u6b7b\u4ea1\u6838\u5fc3\u86cb\u767dGPX4\u8868\u8fbe\u56de\u5347\u3001ACSL4\u8868\u8fbe\u4e0b\u964d\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5185ROS\u53caMDA\u6c34\u5e73\u964d\u4f4e\uff08 P<0.05\uff09\uff0c\u540c\u65f6\u4fc3\u708e\u56e0\u5b50TNF-\u03b1\u6c34\u5e73\u4e0b\u964d\u3001\u6297\u708e\u56e0\u5b50IL-10\u6c34\u5e73\u5347\u9ad8\uff08 P<0.05\uff09\uff1b\u6b64\u5916\uff0c\u81ea\u672f\u540e14 d\u8d77BMS\u8bc4\u5206\u663e\u8457\u9ad8\u4e8e\u635f\u4f24\u7ec4\uff08 P<0.05\uff09\uff0c\u4e14\u810a\u9ad3\u7ec4\u7ec7\u7ed3\u6784\u4fdd\u5b58\u76f8\u5bf9\u5b8c\u597d\uff0c\u7a7a\u6d1e\u9762\u79ef\u51cf\u5c0f\u3002.

In this study, we analyzed 188 ferroptosis-related differentially expressed genes (FRDEGs) at 7\u00a0day (7d) after SCI and identified GADD45A as a central gene in the post-SCI ferroptosis network, with a functional profile closely linked to apoptosis. GADD45A was markedly upregulated in injured spinal cord tissue. In vivo, GADD45A knockdown improved neurological recovery and promoted tissue repair by modulating markers of ferroptosis and apoptosis. In H2O2-treated PC12 cells, GADD45A knockdown reduced the expression of Cleaved Caspase-3, BAX, Cleaved Caspase-9, 4-HNE, and ACSL4, while increasing the expression of BCL-2, GPX4, FTH1, and FPN. It also attenuated H2O2-induced cellular injury. Mechanistically, GADD45A knockdown inhibited NF-\u03baB signaling and reduced nuclear translocation of NF-\u03baB-p65. These protective effects were reversed by the NF-\u03baB activator CU-T12-9. Collectively, these findings suggest that GADD45A promotes neuronal ferroptosis and apoptosis after SCI by regulating the NF-\u03baB pathway, and that GADD45A may be a potential therapeutic target for SCI."

In the central nervous system (CNS), most ferroptosis research has focused on neurons and glial cells, whereas the vulnerability of brain microvascular endothelial cells (BMECs) and its consequences for blood-brain barrier (BBB) integrity remain less clearly defined. Because BMECs form the vascular interface between the circulation and the brain parenchyma, ferroptotic injury in this cell population may represent an immunovascular mechanism through which endothelial redox stress is translated into barrier dysfunction and neuroinflammatory amplification. In this review, we summarize molecular pathways that may promote or restrain BMEC ferroptosis, including iron handling, antioxidant defense mediated by the solute carrier family 7 member 11 (SLC7A11)-glutathione peroxidase 4 (GPX4) axis and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, lipid peroxidation, and junctional remodeling. We then discuss how ferroptosis-associated endothelial injury may contribute to BBB leakage, damage-associated molecular pattern release, innate immune sensing, leukocyte recruitment, glial activation, and self-amplifying inflammatory feedback at the neurovascular interface. We organize the available literature according to the strength and cellular specificity of evidence, separating BMEC-specific findings, BBB-focused in vivo studies, indirect CNS evidence, and mechanistic analogies from non-CNS endothelial systems. Finally, we evaluate disease-specific evidence in ischemic stroke and selected neurodegenerative or inflammatory conditions, together with therapeutic strategies, BMEC-targeting considerations, candidate clinical biomarkers, and translational barriers for modulating endothelial ferroptosis. This review frames endothelial ferroptosis as a promising but incompletely established immunovascular link between BBB dysfunction and neuroinflammation, and highlights the need for BMEC-specific models, human BBB systems, endothelial ferroptosis biomarkers, biomarker-guided monitoring, BMEC-targeted delivery approaches, and careful evaluation of the physiological risks of systemic or prolonged ferroptosis blockade."

Ferroptosis, an iron-dependent form of regulated cell death, contributes significantly to this pathology. This study investigates the hypothesis that miR-10a-5p attenuates spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. A spinal cord I/R injury model was established in male Sprague-Dawley male rats via transient aortic occlusion. Intrathecal injections of the ferroptosis inhibitor Liproxstatin-1 (Lip-1), siRNA targeting ACSL4 or TAK1, and miR-10a-5p agomir/antagomir were administered prior to ischemia induction. Neurological function was assessed using Tarlov scores. Histopathological changes were evaluated by H&E, Nissl, and immunofluorescence staining. Mitochondrial ultrastructure was examined by transmission electron microscopy (TEM). Expression levels of ferroptosis-related markers (ACSL4, GPX4, COX2, FTH1), inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and lipid peroxidation products (MDA, 12-HETE, 15-HETE, LPO) were measured using Western blot, qPCR, and ELISA. The targeting relationship between miR-10a-5p and TAK1 was validated by dual-luciferase reporter assay. Spinal cord I/R injury induced significant neurological deficits, ferroptosis (evidenced by increased iron, MDA, ACSL4, and COX2; decreased GPX4 and GSH), lipid peroxidation, and inflammation. Lip-1 treatment ameliorated these changes. Knockdown of ACSL4 or TAK1 similarly inhibited ferroptosis, reduced inflammation, and improved motor function. Spinal cord I/R injury induced significant downregulation of miR-10a-5p. It directly targeted TAK1, as confirmed by luciferase assay. Consequently, miR-10a-5p overexpression suppressed TAK1/ACSL4 axis, mitigated lipid peroxidation and ferroptosis, and reduced pro-inflammatory cytokine levels (TNF-\u03b1 and IL-1\u03b2), leading to improved neurological outcomes. This study demonstrates that miR-10a-5p plays a protective role in spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. These findings highlight the potential of the miR-10a-5p/TAK1/ACSL4 axis as a novel therapeutic target for preventing and treating spinal cord I/R injury."

Although many therapeutic strategies have been explored to attenuate secondary injury, effective molecularly targeted interventions remain limited. Increasing evidence identifies signal transducer and activator of transcription 3 (STAT3) as a central signaling node in the neurochemical response to SCI. Recent studies indicate that STAT3 exhibits pronounced spatiotemporal and cell-type-specific activation after SCI. Depending on the upstream trigger and cellular compartment involved, STAT3 can amplify or restrain neuroinflammation, shape astrocyte and microglial reactivity, influence mitochondrial bioenergetics and oxidative stress, modulate ferroptosis and apoptosis, and alter the regenerative state of the injured spinal cord. In this review, we frame STAT3 not simply as a downstream effector of the JAK/STAT cascade, but as an integrative regulator of SCI neurochemistry that links cytokine-driven signaling to metabolic stress, glial remodeling, and axonal repair. We emphasize how injury phase, cell type, and subcellular localization influence STAT3-dependent outcomes, discuss emerging therapeutic strategies that converge on STAT3-centered pathways, and outline the key challenges that must be addressed for precise translational targeting."

Tetramethylpyrazine (TMP), a bioactive compound derived from traditional Chinese medicine, possesses a wide range of pharmacological activities and has demonstrated potential therapeutic effects in the treatment of SCI. Therefore, this article provides a comprehensive review of the mechanisms by which TMP promotes spinal cord repair. This review compiles a large body of in vitro, in vivo, and clinical studies, including a total of 86 publications documenting the effects of TMP on SCI. The results indicate that the mechanisms by which TMP exerts its effects in SCI treatment include promoting nerve regeneration, improving vascular dysfunction, exerting anti-inflammatory effects, inhibiting neuronal apoptosis, reducing oxidative stress, regulating iron metabolism, maintaining ion homeostasis, alleviating pyroptosis, and modulating autophagy. Through these mechanisms, TMP contributes to the restoration of spinal cord morphology, motor function, and electrophysiological parameters in experimental animal models. Clinical reports on the use of TMP injection for SCI are relatively limited, and its clinical efficacy requires further investigation. The combined application of nanotechnology or hydrogels provides an efficient targeted delivery and sustained-release system for TMP in the spinal cord, thereby significantly enhancing its bioavailability. Overall, TMP shows promising potential in SCI treatment and may serve as a valuable adjunctive therapeutic strategy."

Previous studies have demonstrated an association between increased level of iron in the lung and aging and age-related lung diseases including pulmonary fibrosis and asthma in the elderly (AIE). However, the mechanisms underlying the accumulation of iron with aging or AIE, or the cell types involved, remain understudied. In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling."

The present study aimed to develop a bioactive therapeutic platform based on an adipose-derived extracellular matrix (ECM) hydrogel incorporating cytokine-releasing PLGA microspheres to promote spinal cord repair. The hydrogel was fabricated from decellularized adipose tissue and combined with microspheres encapsulating interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and glial cell line-derived neurotrophic factor (GDNF) to achieve sustained cytokine delivery. Seventy-five male Sprague-Dawley rats were randomly allocated into five experimental groups, including control, SCI, hydrogel, microsphere, and Hydrogel\u2009+\u2009Mic groups. Tissue specimens were subsequently harvested from the lesion site for further analyses. In a rat model of SCI, treatment with the cytokine-releasing microsphere-loaded hydrogel significantly improved electrophysiological conduction and locomotor recovery compared with untreated SCI animals and groups receiving individual treatments. Molecular analyses demonstrated that the combined treatment markedly suppressed the expression of pro-inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Additionally, apoptosis-related markers showed substantial modulation, characterized by decreased Caspase-3 and Bax expression and increased Bcl-2 levels. The therapy also improved the oxidative balance by increasing antioxidant markers including GSH, SOD, and CAT while reducing the lipid peroxidation marker MDA. Furthermore, ferroptosis-associated biomarkers were significantly regulated, with elevated levels of GSH, GPX4, and SLC7A11 and reduced ACSL4 expression. Histological analyses revealed significant preservation of spinal cord architecture, reduced cavity formation, enhanced neuronal survival, and decreased glial activation in animals treated with the composite hydrogel system. Collectively, these findings demonstrate that adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres provides a multifunctional therapeutic strategy that attenuates inflammation, apoptosis, oxidative stress, and ferroptosis, ultimately promoting structural and functional recovery following spinal cord injury."

Rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation. In this review, we summarize the molecular mechanisms by which microglial ferroptosis mediates neuroinflammatory responses, with a focus on iron homeostasis disruption, lipid peroxidation and ROS amplification, collapse of the GPX4-dependent antioxidant defense, mitochondrial ROS generation, and inflammasome activation. We further classify related CNS diseases into three categories according to disease course and pathological features: chronic neurodegenerative and demyelinating diseases, acute CNS injuries, and neuropsychiatric or systemic inflammation-related brain dysfunction. Within this framework, we compare the pathological significance of microglial ferroptosis across different disease contexts. We also discuss potential therapeutic strategies targeting iron homeostasis, lipid peroxidation, antioxidant defenses, inflammatory amplification networks, and microglia-specific delivery systems. Finally, we address current challenges in the field, including insufficient cell-type specificity, inconsistent detection criteria, disease-stage heterogeneity, and barriers to clinical translation. This review provides an integrated perspective on the mechanisms by which microglial ferroptosis drives neuroinflammation and highlights its potential relevance for precision intervention in CNS diseases."

This study aimed to investigate the role of ferroptosis in CA-induced spinal cord injury and to evaluate the neuroprotective effects of edaravone. Asphyxial CA was induced in rats for 5\u202fmin, followed by resuscitation. Edaravone was administered immediately after the return of spontaneous circulation (ROSC). At 24\u202fh post-ROSC, The CA group exhibited significant hindlimb motor deficits and reduced survival rates. Histological analysis revealed selective injury of choline acetyltransferase (ChAT)-positive motor neurons in the lumbar spinal cord, accompanied by mitochondrial shrinkage and membrane rupture, which are characteristic of ferroptosis. Immunofluorescence demonstrated a selective upregulation of the pro-ferroptotic enzyme acyl-CoA synthetase long-chain family member 4 (ACSL4) specifically in ChAT-positive motor neurons, whereas glutathione peroxidase 4 (GPX4) expression remained relatively preserved. Edaravone treatment significantly improved neurological outcomes and survival, attenuated lipid peroxidation (evidenced by decreased malondialdehyde and preserved glutathione levels), and effectively suppressed ACSL4 upregulation in the motor neurons. Furthermore, edaravone mitigated neuroinflammation by reducing astrogliosis and microglial activation. These findings provide the first evidence that ACSL4-mediated ferroptosis is a key driver of acute spinal motor neuron injury following CA. Edaravone exerts potent neuroprotection by targeting this pathway, suggesting its therapeutic potential for ameliorating spinal cord injury in patients with CA."

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma."

PANoptosis is a newly identified cell death mode that synergistically initiates pyroptosis, apoptosis and necroptosis via activation of PANoptosome. It is closely associated with oxidative stress, neuroinflammation, and secondary injury following TBI and SCI, yet the key pathogenic factors and mechanisms underlying PANoptosis remain incompletely elucidated. Mitochondria, as a central organelle for energy synthesis and oxidative stress, its health and homeostasis are the cornerstone of cell survival and biological function. Emerging evidence suggests that the loss of mitochondrial homeostasis plays a fundamental role in the activation and execution of PANoptosis across various cell types. Here, we review the detailed manifestations of mitochondrial homeostasis imbalance in TBI and SCI, such as impaired biogenesis, abnormal dynamics, mitophagy dysfunction, and mitochondria-derived vesicles. Meanwhile, we systematically analyze the characteristics and pathological effects of PANoptosis cascade following TBI and SCI, with a focus on the regulatory patterns, mechanisms, and potential targets of injured mitochondria driving PANoptosis. In addition, we discuss the advancements and future perspectives of mitochondria-based strategies for modulating PANoptosis in TBI and SCI.

This study aims to investigate the regulatory role of anti-HMGB1 antibody in the depressive-like behaviour of D-SCI rats and to explore its underlying mechanisms. A depression model was established in rats 5\u2009weeks after SCI. The expression of HMGB1 and ferroptosis markers (MDA, GSH and iron ion deposition) in the hippocampus were examined in both the sham group and the D-SCI group. Subsequently, D-SCI rats were treated with an anti-HMGB1 antibody, and the depression-like behaviours of each group were assessed using open field and sucrose preference tests. Ferroptosis levels in the hippocampus, as well as the expression of ferroptosis-related proteins (ACSL4, SLC7A11 and GPX4), were also investigated. The co-localization of HMGB1 and NeuN in the rat hippocampus was detected by immunofluorescence double staining. Furthermore, at the cellular level, the effect of the anti-HMGB1 antibody on Erastin-induced ferroptosis in rat hippocampal neurons was analysed. The results indicated that compared to the sham group, the levels of HMGB1 and ferroptosis in the hippocampus of rats in the D-SCI group were significantly elevated. Administering anti-HMGB1 antibody to D-SCI rats could significantly augment their activity distance, movement speed and sucrose preference rate, while also suppressing the ferroptosis level and the expression of ferroptosis-related proteins in the hippocampus. Moreover, HMGB1 and NeuN were co-expressed in the rat hippocampus. The results from primary rat hippocampal neurons indicated that anti-HMGB1 antibody could inhibit erastin-induced ferroptosis in rat hippocampal neurons. Taken together, anti-HMGB1 antibody therapy can ameliorate depressive behaviour in D-SCI rats; the possible mechanism may involve the inhibition of ferroptosis in hippocampal neurons."

The SCI model was established using a 10\u2009g weight dropped onto the T10 vertebrae in female rats. After functional testing, spinal cords were harvested for biochemical and histopathological assays at different time points. Nissl and Prussian blue staining were used to analyse neuronal death. Neuronal ferroptosis in spinal cords was examined using transmission electron microscopy, and lipid peroxidation in the cultured neurones was analysed. After SCI, S1P (Sphingosine 1-phosphate) was released from crushed spinal cords and subsequently activated the neuronal S1P2 receptor to increase lipid peroxidation, which injured neurones via inducing neuronal ferroptosis through the P-ERK/ERK/ACSL4 pathway, resulting in limb paralysis. S1P2 receptor inhibition significantly blocked S1P2 receptor activation and attenuated neuronal ferroptosis. Thus, S1P2 receptor was a therapeutic target for the treatment of SCI. Systemic administration of the S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) effectively promoted locomotor function recovery by attenuating neuronal ferroptosis in rat spinal cords.

Primary microglia cells were extracted from neonatal 1-2 days C57BL/6 mice and divided into control group, Yoda1 (Piezo1 agonist) group, and Yoda1+GsMTx4 (Piezo1 inhibitor) group. Live/dead cell staining, reactive oxygen species (ROS) fluorescence staining, 5, 5', 6, 6'-tetrachloro-1, 1', 3, 3'-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) mitochondrial membrane potential detection, and transmission electron microscopy were utilized to assess microglial ferroptosis and mitochondrial functional characteristics. SPF female C57BL/6 mice aged 6 to 8 weeks were used to detect the expression of Piezo1 at different time points after SCI by Western blot, and the two time points with no significant change and the most significant change in Piezo1 expression after SCI were selected for subsequent experiments. T 8, T 9 SCI models were established by modified Allen's method, and were divided into sham operation group, injury group, and injury+shPiezo1 group (Piezo1-targeted interfering virus AAV-shPiezo1 was injected in situ to knock down the expression of Piezo1 14 days before modeling). Colocalization of Piezo1 with microglial markers purinergic receptor P2Y12 (P2ry12), and the expressions of glutathione peroxidase 4 (GPX4) and acyl coenzyme A synthetase long chain member 4 (ACSL4) were observed by immunofluorescence staining.

The level of ROS was detected by dihydroethidium (DHE) staining; the content of malondialdehyde (MDA) was detected by MDA kit; the levels of tumor necrosis factor \u03b1 (TNF-\u03b1) and interleukin 10 (IL-10) were detected by ELISA assay; the pathological morphology of spinal cord was observed by HE staining. In vitro experiments showed that compared with the control group, the Yoda1 group had typical ultrastructural changes of ferroptosis, such as increased microglial cell death, enhanced ROS fluorescence, mitochondrial membrane potential depolarization, mitochondrial shrinkage and mitochondrial cristae breakage (all P<0.05), while the GsMTx4 group could partially reverse the above effects ( P<0.05). In vivo experiments demonstrated that the expression of Piezo1 in spinal cord tissue was up-regulated sequentially after SCI, and reached the peak on the 7th day after SCI ( P<0.05), and it was mainly localized in P2ry12-positive microglia. Compared with the injury group, in the injury+shPiezo1 group, the expression of ferroptosis core protein GPX4 in microglia was increased, the expression of ACSL4 was decreased, the levels of ROS and MDA in spinal cord tissue were decreased ( P<0.05), the level of pro-inflammatory factor TNF-\u03b1 was decreased, and the level of anti-inflammatory factor IL-10 was increased ( P<0.05). In addition, the BMS score was significantly higher than that of the injury group ( P<0.05) from the 14th day after operation, and the spinal cord tissue structure was relatively well preserved, and the cavity area was reduced. SCI activates the Piezo1 channel in microglia, triggering mitochondrial dysfunction and mediating cellular ferroptosis, thereby aggravating secondary neuroinflammation. Targeted inhibition of Piezo1 effectively blocks the ferroptosis process, ameliorates the immune microenvironment, and promotes tissue repair and locomotor functional recovery after SCI. \u63a2\u7a76\u673a\u68b0\u654f\u611f\u6027\u79bb\u5b50\u901a\u9053Piezo1\u5728\u810a\u9ad3\u635f\u4f24\uff08spinal cord injury\uff0cSCI\uff09\u540e\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u4e2d\u7684\u4f5c\u7528\u673a\u5236\uff0c\u5e76\u8bc4\u4f30\u6291\u5236Piezo1\u5bf9\u6539\u5584\u635f\u4f24\u5fae\u73af\u5883\u53ca\u4fc3\u8fdb\u795e\u7ecf\u529f\u80fd\u6062\u590d\u7684\u5f71\u54cd\u3002. \u63d0\u53d6\u65b0\u751f1\uff5e2 d C57BL/6\u5c0f\u9f20\u539f\u4ee3\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001Yoda1\uff08Piezo1\u6fc0\u52a8\u5242\uff09\u7ec4\u53caYoda1+GsMTx4\uff08Piezo1\u6291\u5236\u5242\uff09\u7ec4\u3002\u5229\u7528\u6d3b\u6b7b\u7ec6\u80de\u67d3\u8272\u3001\u6d3b\u6027\u6c27\uff08reactive oxygen species\uff0cROS\uff09\u8367\u5149\u67d3\u8272\u30015\uff0c5\u2019\uff0c6\uff0c6\u2019-\u56db\u6c2f-1\uff0c1\u2019\uff0c3\uff0c3\u2019-\u56db\u4e59\u57fa\u82ef\u5e76\u54aa\u5511\u78b3\u82b1\u9752\u7898\u5316\u7269\uff085\uff0c5\u2019\uff0c6\uff0c6\u2019-tetrachloro-1\uff0c1\u2019\uff0c3\uff0c3\u2019-tetraethylbenzimidazolylcarbocyanine iodide\uff0cJC-1\uff09\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u68c0\u6d4b\u53ca\u900f\u5c04\u7535\u955c\u89c2\u5bdf\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u53ca\u7ebf\u7c92\u4f53\u529f\u80fd\u7279\u5f81\u3002\u53d66\uff5e8\u5468\u9f84SPF\u7ea7\u96cc\u6027C57BL/6\u5c0f\u9f20\uff0c\u91c7\u7528Western blot\u68c0\u6d4bPiezo1\u5728SCI\u540e\u4e0d\u540c\u65f6\u95f4\u70b9\u7684\u8868\u8fbe\u89c4\u5f8b\uff0c\u9009\u53d6\u635f\u4f24\u540ePiezo1\u8868\u8fbe\u672a\u89c1\u660e\u663e\u6539\u53d8\u53ca\u53d8\u5316\u6700\u663e\u8457\u76842\u4e2a\u65f6\u95f4\u70b9\u8fdb\u884c\u540e\u7eed\u5b9e\u9a8c\u3002\u91c7\u7528\u6539\u826fAllen\u6cd5\u5236\u5907T 8\u3001T 9 SCI\u6a21\u578b\uff1b\u5b9e\u9a8c\u5206\u4e3a\u5047\u624b\u672f\u7ec4\u3001\u635f\u4f24\u7ec4\u548c\u635f\u4f24+shPiezo1\u7ec4\uff08\u9020\u6a21\u524d14 d\u539f\u4f4d\u6ce8\u5c04\u9776\u5411Piezo1\u7684\u5e72\u6270\u75c5\u6bd2AAV-shPiezo1\u4ee5\u6572\u4f4ePiezo1\u8868\u8fbe\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u89c2\u5bdfPiezo1\u4e0e\u5c0f\u80f6\u8d28\u7ec6\u80de\u6807\u5fd7\u7269\u560c\u5464\u80fd\u53d7\u4f53P2Y12\uff08purinergic receptor P2Y12\uff0cP2ry12\uff09\u7684\u5171\u5b9a\u4f4d\u53ca\u8c37\u80f1\u7518\u80bd\u8fc7\u6c27\u5316\u7269\u91764\uff08glutathione peroxidase 4\uff0cGPX4\uff09\u3001\u9170\u57fa\u8f85\u9176A\u5408\u6210\u9176\u957f\u94fe\u5bb6\u65cf\u6210\u54584\uff08acyl coenzyme A synthetase long chain member 4\uff0cACSL4\uff09\u7684\u8868\u8fbe\uff1bBasso Mouse Scale\uff08BMS\uff09\u8bc4\u5206\u8bc4\u4f30\u5c0f\u9f20\u540e\u80a2\u8fd0\u52a8\u529f\u80fd\uff1b\u4e8c\u6c22\u4e59\u952d\uff08dihydroethidium\uff0cDHE\uff09\u67d3\u8272\u68c0\u6d4b\u7ec4\u7ec7ROS\u6c34\u5e73\uff1b\u4e19\u4e8c\u919b\uff08malondialdehyde\uff0cMDA\uff09\u8bd5\u5242\u76d2\u68c0\u6d4bMDA\u542b\u91cf\uff1bELISA\u68c0\u6d4b\u708e\u75c7\u56e0\u5b50TNF-\u03b1\u3001IL-10\u6c34\u5e73\uff1bHE\u67d3\u8272\u89c2\u5bdf\u810a\u9ad3\u7ec4\u7ec7\u75c5\u7406\u5f62\u6001\u3002. \u4f53\u5916\u5b9e\u9a8c\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cYoda1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u6b7b\u4ea1\u589e\u591a\u3001ROS\u8367\u5149\u589e\u5f3a\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u53bb\u6781\u5316\u3001\u7ebf\u7c92\u4f53\u51fa\u73b0\u76b1\u7f29\u53ca\u5d74\u65ad\u88c2\u7b49\u94c1\u6b7b\u4ea1\u5178\u578b\u8d85\u5fae\u7ed3\u6784\u6539\u53d8\uff08\u5747 P<0.05\uff09\uff1b\u800cGsMTx4\u7ec4\u53ef\u90e8\u5206\u9006\u8f6c\u4e0a\u8ff0\u6548\u5e94\uff08 P<0.05\uff09\u3002\u4f53\u5185\u5b9e\u9a8c\u793a\uff0cSCI\u540e\u810a\u9ad3\u7ec4\u7ec7\u4e2dPiezo1\u8868\u8fbe\u5448\u65f6\u5e8f\u6027\u4e0a\u8c03\uff0c\u672f\u540e7 d\u8fbe\u5cf0\u503c\uff08 P<0.05\uff09\uff0c\u4e14\u4e3b\u8981\u5b9a\u4f4d\u4e8eP2ry12\u9633\u6027\u5c0f\u80f6\u8d28\u7ec6\u80de\u3002\u4e0e\u635f\u4f24\u7ec4\u6bd4\u8f83\uff0c\u635f\u4f24+shPiezo1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u5185\u94c1\u6b7b\u4ea1\u6838\u5fc3\u86cb\u767dGPX4\u8868\u8fbe\u56de\u5347\u3001ACSL4\u8868\u8fbe\u4e0b\u964d\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5185ROS\u53caMDA\u6c34\u5e73\u964d\u4f4e\uff08 P<0.05\uff09\uff0c\u540c\u65f6\u4fc3\u708e\u56e0\u5b50TNF-\u03b1\u6c34\u5e73\u4e0b\u964d\u3001\u6297\u708e\u56e0\u5b50IL-10\u6c34\u5e73\u5347\u9ad8\uff08 P<0.05\uff09\uff1b\u6b64\u5916\uff0c\u81ea\u672f\u540e14 d\u8d77BMS\u8bc4\u5206\u663e\u8457\u9ad8\u4e8e\u635f\u4f24\u7ec4\uff08 P<0.05\uff09\uff0c\u4e14\u810a\u9ad3\u7ec4\u7ec7\u7ed3\u6784\u4fdd\u5b58\u76f8\u5bf9\u5b8c\u597d\uff0c\u7a7a\u6d1e\u9762\u79ef\u51cf\u5c0f\u3002.

In this study, we analyzed 188 ferroptosis-related differentially expressed genes (FRDEGs) at 7\u00a0day (7d) after SCI and identified GADD45A as a central gene in the post-SCI ferroptosis network, with a functional profile closely linked to apoptosis. GADD45A was markedly upregulated in injured spinal cord tissue. In vivo, GADD45A knockdown improved neurological recovery and promoted tissue repair by modulating markers of ferroptosis and apoptosis. In H2O2-treated PC12 cells, GADD45A knockdown reduced the expression of Cleaved Caspase-3, BAX, Cleaved Caspase-9, 4-HNE, and ACSL4, while increasing the expression of BCL-2, GPX4, FTH1, and FPN. It also attenuated H2O2-induced cellular injury. Mechanistically, GADD45A knockdown inhibited NF-\u03baB signaling and reduced nuclear translocation of NF-\u03baB-p65. These protective effects were reversed by the NF-\u03baB activator CU-T12-9. Collectively, these findings suggest that GADD45A promotes neuronal ferroptosis and apoptosis after SCI by regulating the NF-\u03baB pathway, and that GADD45A may be a potential therapeutic target for SCI."

In the central nervous system (CNS), most ferroptosis research has focused on neurons and glial cells, whereas the vulnerability of brain microvascular endothelial cells (BMECs) and its consequences for blood-brain barrier (BBB) integrity remain less clearly defined. Because BMECs form the vascular interface between the circulation and the brain parenchyma, ferroptotic injury in this cell population may represent an immunovascular mechanism through which endothelial redox stress is translated into barrier dysfunction and neuroinflammatory amplification. In this review, we summarize molecular pathways that may promote or restrain BMEC ferroptosis, including iron handling, antioxidant defense mediated by the solute carrier family 7 member 11 (SLC7A11)-glutathione peroxidase 4 (GPX4) axis and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, lipid peroxidation, and junctional remodeling. We then discuss how ferroptosis-associated endothelial injury may contribute to BBB leakage, damage-associated molecular pattern release, innate immune sensing, leukocyte recruitment, glial activation, and self-amplifying inflammatory feedback at the neurovascular interface. We organize the available literature according to the strength and cellular specificity of evidence, separating BMEC-specific findings, BBB-focused in vivo studies, indirect CNS evidence, and mechanistic analogies from non-CNS endothelial systems. Finally, we evaluate disease-specific evidence in ischemic stroke and selected neurodegenerative or inflammatory conditions, together with therapeutic strategies, BMEC-targeting considerations, candidate clinical biomarkers, and translational barriers for modulating endothelial ferroptosis. This review frames endothelial ferroptosis as a promising but incompletely established immunovascular link between BBB dysfunction and neuroinflammation, and highlights the need for BMEC-specific models, human BBB systems, endothelial ferroptosis biomarkers, biomarker-guided monitoring, BMEC-targeted delivery approaches, and careful evaluation of the physiological risks of systemic or prolonged ferroptosis blockade."

Although many therapeutic strategies have been explored to attenuate secondary injury, effective molecularly targeted interventions remain limited. Increasing evidence identifies signal transducer and activator of transcription 3 (STAT3) as a central signaling node in the neurochemical response to SCI. Recent studies indicate that STAT3 exhibits pronounced spatiotemporal and cell-type-specific activation after SCI. Depending on the upstream trigger and cellular compartment involved, STAT3 can amplify or restrain neuroinflammation, shape astrocyte and microglial reactivity, influence mitochondrial bioenergetics and oxidative stress, modulate ferroptosis and apoptosis, and alter the regenerative state of the injured spinal cord. In this review, we frame STAT3 not simply as a downstream effector of the JAK/STAT cascade, but as an integrative regulator of SCI neurochemistry that links cytokine-driven signaling to metabolic stress, glial remodeling, and axonal repair. We emphasize how injury phase, cell type, and subcellular localization influence STAT3-dependent outcomes, discuss emerging therapeutic strategies that converge on STAT3-centered pathways, and outline the key challenges that must be addressed for precise translational targeting."

Tetramethylpyrazine (TMP), a bioactive compound derived from traditional Chinese medicine, possesses a wide range of pharmacological activities and has demonstrated potential therapeutic effects in the treatment of SCI. Therefore, this article provides a comprehensive review of the mechanisms by which TMP promotes spinal cord repair. This review compiles a large body of in vitro, in vivo, and clinical studies, including a total of 86 publications documenting the effects of TMP on SCI. The results indicate that the mechanisms by which TMP exerts its effects in SCI treatment include promoting nerve regeneration, improving vascular dysfunction, exerting anti-inflammatory effects, inhibiting neuronal apoptosis, reducing oxidative stress, regulating iron metabolism, maintaining ion homeostasis, alleviating pyroptosis, and modulating autophagy. Through these mechanisms, TMP contributes to the restoration of spinal cord morphology, motor function, and electrophysiological parameters in experimental animal models. Clinical reports on the use of TMP injection for SCI are relatively limited, and its clinical efficacy requires further investigation. The combined application of nanotechnology or hydrogels provides an efficient targeted delivery and sustained-release system for TMP in the spinal cord, thereby significantly enhancing its bioavailability. Overall, TMP shows promising potential in SCI treatment and may serve as a valuable adjunctive therapeutic strategy."

Previous studies have demonstrated an association between increased level of iron in the lung and aging and age-related lung diseases including pulmonary fibrosis and asthma in the elderly (AIE). However, the mechanisms underlying the accumulation of iron with aging or AIE, or the cell types involved, remain understudied. In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling."

The present study aimed to develop a bioactive therapeutic platform based on an adipose-derived extracellular matrix (ECM) hydrogel incorporating cytokine-releasing PLGA microspheres to promote spinal cord repair. The hydrogel was fabricated from decellularized adipose tissue and combined with microspheres encapsulating interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and glial cell line-derived neurotrophic factor (GDNF) to achieve sustained cytokine delivery. Seventy-five male Sprague-Dawley rats were randomly allocated into five experimental groups, including control, SCI, hydrogel, microsphere, and Hydrogel\u2009+\u2009Mic groups. Tissue specimens were subsequently harvested from the lesion site for further analyses. In a rat model of SCI, treatment with the cytokine-releasing microsphere-loaded hydrogel significantly improved electrophysiological conduction and locomotor recovery compared with untreated SCI animals and groups receiving individual treatments. Molecular analyses demonstrated that the combined treatment markedly suppressed the expression of pro-inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Additionally, apoptosis-related markers showed substantial modulation, characterized by decreased Caspase-3 and Bax expression and increased Bcl-2 levels. The therapy also improved the oxidative balance by increasing antioxidant markers including GSH, SOD, and CAT while reducing the lipid peroxidation marker MDA. Furthermore, ferroptosis-associated biomarkers were significantly regulated, with elevated levels of GSH, GPX4, and SLC7A11 and reduced ACSL4 expression. Histological analyses revealed significant preservation of spinal cord architecture, reduced cavity formation, enhanced neuronal survival, and decreased glial activation in animals treated with the composite hydrogel system. Collectively, these findings demonstrate that adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres provides a multifunctional therapeutic strategy that attenuates inflammation, apoptosis, oxidative stress, and ferroptosis, ultimately promoting structural and functional recovery following spinal cord injury."

However, its direct involvement in cardiomyocyte injury mechanisms remains unclear. This study aimed to investigate the effects of Lp(a) on cardiomyocytes. A combination of in vitro cell culture and in vivo small animal models were used for investigations. Lp(a) induced ferroptosis through a redox-sensitive pathway via sequential p38 MAPK activation and p53-mediated transcriptional regulation. Exposure of AC16 human cardiomyocytes to Lp(a) triggered hallmark ferroptotic events, including intracellular Fe2+ accumulation, an increase in malondialdehyde (MDA) levels, and concurrent increases in p38 MAPK (p-p38) phosphorylation. Pharmacological blockade of p38 using SB203580 or siRNA-mediated p38 silencing significantly attenuated these ferroptotic markers, confirming the central role of p38 in sensitizing cardiomyocytes to ferroptosis. p38 activation drove the nuclear translocation of p53, with both pharmacological p53 inhibition (pifithrin-\u03b1) and genetic p53 knockdown effectively mitigating Lp(a)-induced lipid peroxidation and cell death. Furthermore, Lp(a) promoted an increase in intracellular reactive oxygen species (ROS) levels and initiated p38 phosphorylation, subsequently activating p53 to suppress SLC7A11 expression. These cellular findings were validated in vivo using Lp(a)-treated C57BL/6J mice, which recapitulated cardiac dysfunction, as indicated by characteristic ferroptotic markers: myocardial Fe2+/MDA elevation, glutathione/cysteine depletion, and p38-p53 axis activation. Lp(a) activates p38 by increasing intracellular ROS levels and promotes ferroptosis in cardiomyocytes via SLC7A11 inhibition, which depends on p53 activation."

The core pathological event of CaOx crystals is the damage of renal tubular epithelial cells (RTECs). Recent studies have shown that CaOx crystals can induce a variety of programmed cell death (PCD) pathways, such as apoptosis, pyroptosis, necroptosis, and ferroptosis, in RTECs at the same time, and there are complex compensations and crosstalk between these death pathways, resulting in the limited efficacy of a single targeting strategy. Therefore, exploring the mechanisms that can integrate the regulation of multiple cell death pathways has become an important direction in this field. PANoptosis is an inflammatory PCD mode driven by the PANoptosome complex, which synchronously triggers the characteristic events of three death pathways in the same cell through the cooperative integration of the core molecular components of pyroptosis, apoptosis, and necroptosis. In this process, cysteinyl aspartate-specific proteinase-8 (Caspase-8) and receptor-interacting serine/threonine kinase 3 (RIPK3), as the core components of the PANoptosome, jointly determine whether the cell goes to a single programmed death or an integrated PANoptosis. The limited studies' evidence supports that CaOx crystals induce concurrent activation of apoptosis, pyroptosis, and necroptosis, suggesting the possibility of PANoptosis in CaOx\u2011induced kidney injury. At the same time, the rupture of the cell membrane caused by PANoptosis, similar to other forms of PCD, releases a large number of damage-associated molecular patterns (DAMPs), which activate innate immunity to form an inflammatory cascade and further aggravates tissue damage. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. In the future, new biomarkers and multi-target intervention strategies should be developed based on PANoptosis, which is expected to open up a new path for the prevention and treatment of CaOx-induced kidney injury."

This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. Neural tissue is particularly sensitive to oxidative stress, mitochondrial dysfunction, immune-mediated inflammation, and blood-brain barrier disruption. These pathological changes are common in many forms of neural injury. Therefore, abnormal PANoptosis activation may provide a common mechanism linking different types of nervous system damage. This review summarizes the historical evolution, molecular mechanisms, disease-related roles, and intervention strategies of PANoptosis in neurological disorders. It focuses on PANoptosome assembly and key mechanistic nodes, including NOD-like receptor family pyrin domain-containing 3 (NLRP3), caspase-8, the receptor-interacting serine/threonine protein kinase 1 (RIPK1)/receptor-interacting serine/threonine protein kinase 3 (RIPK3)/mixed lineage kinase domain-like protein (MLKL) axis, gasdermin D (GSDMD), and Ninjurin 1 (NINJ1).

However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse."

Brains and spinal cords were collected 2-3\u00a0weeks post-injection or between 6-10 and 11-15\u00a0months of age. Immunohistochemical studies of transgene expression throughout the brain and spinal cord using an antibody selective for human APP (hAPP) revealed age-dependent accumulation of clusters of hAPP-positive granules in areas containing hAPP-labeled neuronal cell bodies. Surprisingly, there were also hAPP-positive granules in regions containing axons and synaptic terminals from hAPP expressing neurons. Moreover, tdT expressed by CSNs accumulated in the same granules as hAPP, and both tdT and hAPP were present in clusters of granules with other markers of AD pathology. Quantitative assessments confirmed age-related degeneration of layer V CSNs accompanied by progressive accumulation of clusters of tdT and hAPP-positive granules. Overall, our results indicate that accumulation of aggregated hAPP in areas containing axons and synaptic terminals from hAPP expressing neurons is a prominent feature of AD pathophysiology in 5xFAD mice and that accumulation of clusters of hAPP granules provides a secondary measure to track neurodegeneration of identified populations of genetically labeled neurons."

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma."

Building on our previous work, which identified compound 20 as a promising antioxidant and neuroprotective agent, the present study investigates the molecular mechanisms underlying its protective activity against amyloid-induced ferroptosis in human neuroblastoma SH-SY5Y cells exposed to A\u03b2(25-35). Compound 20 (3-(((4-hydroxybenzyl)(methyl)amino)methyl)-1-methyl-N-(2-(piperazin-1-yl)ethyl)-1H-indole-5-carboxamide) markedly counteracted A\u03b2(25-35)-induced ferroptotic damage by restoring intracellular glutathione levels, depleting the labile iron pool, and suppressing lipid peroxidation. In parallel, the compound significantly rescued mitochondrial membrane potential and attenuated endoplasmic reticulum (ER) expansion associated with ER stress, thereby preserving cellular homeostasis under oxidative challenge. These protective effects were further corroborated by real-time PCR analysis, which revealed the modulation of key genes involved in the oxidative stress response, endoplasmic reticulum stress, and inflammatory pathways. To gain a systems-level insight into these mechanisms, untargeted 1H-NMR metabolomic profiling was performed. This analysis confirmed the activation of antioxidant pathways and disclosed a significant modulation of energy metabolism and GABA-related pathways, both of which are closely linked to redox balance and neuronal resilience. Overall, these findings demonstrate that compound 20 drives metabolic reprogramming that orchestrates its multifactorial protective effect against A\u03b2(25-35)-induced ferroptosis by coordinating antioxidant defense, iron homeostasis, and ER stress mitigation."

The degenerative disc's harsh microenvironment promotes nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) death and hinders self repair. Mesencephalic astrocyte-derived neurotrophic factor (MANF), an atypical neurotrophic factor, has protective effects in degenerative diseases. However, its role in IDD is unclear. Assessment of MANF expression was conducted in both human nucleus pulposus tissues and a rat IVD puncture model. An in vitro model of degeneration was established by acid treatment of NP-MSCs, and the functional role of MANF was explored through its knockdown and overexpression. RNA sequencing was employed to identify downstream targets. The therapeutic potential of MANF-overexpressing NP-MSCs was evaluated in a rat puncture model. MANF expression was markedly downregulated in degenerated IVD tissues from both human patients and rat models. Correspondingly, in vitro experiments demonstrated that MANF knockdown exacerbated, while its overexpression mitigated, acid-induced apoptosis of NP-MSCs. Mechanistically, MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity, as demonstrated by the complete abolition of this protection upon treatment with the MAM uncoupler FATE1. Transcriptomic analysis and subsequent validation identified receptor expression-enhancing protein 1 (REEP1) as a critical downstream effector through which MANF safeguards MAM integrity. We further elucidated that MANF upregulates REEP1 expression by directly inhibiting miR-33b-5p. In vivo, transplantation of MANF-overexpressing NP-MSCs effectively attenuated IDD in a rat model. MANF protected NP-MSCs from acidosis by sustaining MAM integrity via the MiR-33b-5p/REEP1 axis. These findings reveal MANF's mechanism and therapeutic potential for IDD."

Increasing evidence indicates that regulated cell death (RCD) can act as an upstream amplifier in selected autoimmune settings, while in other settings it may mainly report downstream collateral injury caused by cytotoxic lymphocytes, immune complexes, complement activation, or tissue hypoxia. Accordingly, this review distinguishes causal death execution from associative pathway signatures and highlights the types of longitudinal, cell-type-resolved, and perturbational evidence needed to make that distinction. We summarize how apoptosis, necroptosis, pyroptosis, and ferroptosis operate as an interlocking network in autoimmune microenvironments, frequently co-existing as context-dependent mixed-death states driven by shared triggers such as cytokines, PRR ligands, and oxidative stress, and governed by decision hubs including RIPK1 and caspase-8. We highlight integrated concepts such as PANoptosis to explain pathway convergence and compensatory switching into parallel lytic branches when a single node is constrained. The review further connects mechanistic insights to translational priorities, emphasizing biomarker strategies that report pathway engagement, targeted modulation of executors or upstream sensing and cytokine circuits, and lesion-localized delivery approaches to improve the therapeutic window. Finally, we outline key gaps that must be addressed to enable precision interventions, including spatial and cell-type resolved validation of death programs, longitudinal profiling across flare-remission trajectories, and harmonized composite panels capable of capturing mixed-death dynamics in heterogeneous AIDs."

While metabolic reprogramming is linked to immune evasion, the precise mechanistic orchestration remains unclear. Here, utilizing single-cell transcriptomics and quantitative lactylome profiling, we show that elevated tumor lactate drives resistance by broadly suppressing PANoptosis. Mechanistically, under chemotherapeutic stress, the Lysine acetyltransferase 8 (KAT8) catalyzes the specific lactylation of the inner mitochondrial membrane ADP/ATP translocator 2 (ANT2)\u00a0at K92. Lactylated ANT2 recruits the phosphoglycerate mutase 5\u00a0(PGAM5) to dephosphorylate Cyclophilin D (CypD). This cascade restricts mitochondrial permeability transition pore (mPTP) opening, preserving mitochondrial homeostasis and averting immunogenic cell death. Crucially, a cell-penetrating competitive peptide targeting the KAT8-ANT2 interface effectively uncouples this metabolic lock, re-sensitizing TNBC tumors to cytotoxic stress and restoring chemo-immunotherapy efficacy in vivo. Our findings unveil a profound mechanistic link between the Warburg effect and mitochondrial homeostasis, establishing KAT8-mediated ANT2 lactylation as a targetable vulnerability to improve chemo-immunotherapy efficacy."

While these responses can be beneficial in host defense, aberrant activation of inflammatory, lytic cell death pathways can be pathogenic. Emerging evidence suggests that cellular metabolic disruption can promote inflammatory cell death, but the mechanistic connections between these processes are not well understood, limiting our ability to identify regulatory nodes that can be therapeutically targeted. Here, we found that intracellular levels of the metabolic cofactor nicotinamide adenine dinucleotide (NAD+) were depleted in response to cell death triggers that drive pyroptosis, necroptosis, PANoptosis, and ferroptosis. However, restoring NAD+ inhibited PANoptosis but not the other forms of cell death. Mechanistically, NAD+ restoration reduced the expression of PANoptotic sensors or regulators, including the transcription factor IRF1, a critical factor for innate immune sensor priming in PANoptosis. Our findings thereby suggest that NAD+ depletion is an early cell death signaling event and that restoring NAD+ levels specifically blocks PANoptosis by suppressing priming. Hence, targeting NAD+ metabolism represents a potential therapeutic strategy for infectious and inflammatory diseases associated with dysregulated PANoptosis."

While pharmacological, psychological, and physiotherapeutic approaches have been applied, including whole-body vibration (WBV), synaptic-level mechanisms of WBV remain largely unexplored. Here, we assessed the post-SCI pain-associated behavior index (PAB, based on established behavioral criteria) and compared synapse counts (SYN+, VGLUT1+, ChAT+, VGAT+), CGRP+- and SER+-structures, as well as astrocytic and microglial populations in the lumbar dorsal horn following thoracic SCI in WBV-treated and untreated rats. Animals received WBV from postoperative week 3 to 12, and outcomes were compared with non-treated controls. PAB was consistently reduced in WBV-treated animals. STED-microscopy quantification showed that WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals, as well as the number of SER\u2009+\u2009fibers. Conversely, WBV reduced CGRP\u2009+\u2009structures in the dorsal horn, decreased the density of CGRP\u2009+\u2009perisomatic and axo-axonic synapses, and lowered astrocytic and microglial populations. Our data indicate that the WBV-induced frequent (15-30\u2005Hz) muscle contractions and proprioceptive impulses contribute to spasticity modulation (via VGAT-related mechanisms) and attenuation of post-SCI hyperalgesia (CGRP-associated). Together with the reduced astro- and microglia amounts, the described synaptic alterations are considered essential prerequisites for better motor recovery. These findings provide preclinical evidence for the functional benefits of WBV in an animal SCI model and warrant further investigations to determine mechanisms underpinning this non-invasive, low-cost and easily applicable rehabilitation approach."

These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors."

Neuronal apoptosis constitutes a critical pathological event leading to neurological dysfunctions, which is further exacerbated by oxidative stress following SCI. Esculentoside A (EsA), a bioactive saponin isolated from Phytolaca esculenta, exhibits neuroprotective potential in our preliminary studies. However, whether EsA attenuates oxidative stress and neuronal apoptosis in SCI remains unclear. The current study aimed to investigate the protective potential of EsA against oxidative stress and neuronal apoptosis following SCI, and to elucidate the associated molecular mechanisms. SCI was modeled in rats via contusion using the PSI-IH 0400 Striker impactor, and rats were treated intraperitoneally with 10 mg/kg EsA once daily. The Basso, Beattie, and Bresnahan (BBB) scale, grid walk analysis, and footprint test were adopted to evaluate motor function dynamically. Histopathological alterations in spinal cord tissue were examined by Hematoxylin-eosin (HE), Luxol Fast Blue (LFB), and Nissl staining. Oxidative stress markers, including hydrogen peroxide (H2O2) and malondialdehyde (MDA), along with antioxidant enzymes glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD), were quantified in spinal cord homogenates using commercial assay kits. Western blot, immunofluorescence staining, and molecular docking were employed to investigate the underlying mechanisms. EsA significantly improved motor function and reduced histopathological damage in SCI rats. This neuroprotective effect was accompanied by a significant improvement in oxidative stress biomarkers and neuronal apoptosis in the injured spinal cord, coinciding with activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. In conclusion, EsA exerts a neuroprotective effect against SCI by modulating oxidative stress and neuronal apoptosis partially through activation of the Nrf2/HO-1 pathway, indicating its promise as a therapeutic agent for SCI."

However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse."

The core pathological event of CaOx crystals is the damage of renal tubular epithelial cells (RTECs). Recent studies have shown that CaOx crystals can induce a variety of programmed cell death (PCD) pathways, such as apoptosis, pyroptosis, necroptosis, and ferroptosis, in RTECs at the same time, and there are complex compensations and crosstalk between these death pathways, resulting in the limited efficacy of a single targeting strategy. Therefore, exploring the mechanisms that can integrate the regulation of multiple cell death pathways has become an important direction in this field. PANoptosis is an inflammatory PCD mode driven by the PANoptosome complex, which synchronously triggers the characteristic events of three death pathways in the same cell through the cooperative integration of the core molecular components of pyroptosis, apoptosis, and necroptosis. In this process, cysteinyl aspartate-specific proteinase-8 (Caspase-8) and receptor-interacting serine/threonine kinase 3 (RIPK3), as the core components of the PANoptosome, jointly determine whether the cell goes to a single programmed death or an integrated PANoptosis. The limited studies' evidence supports that CaOx crystals induce concurrent activation of apoptosis, pyroptosis, and necroptosis, suggesting the possibility of PANoptosis in CaOx\u2011induced kidney injury. At the same time, the rupture of the cell membrane caused by PANoptosis, similar to other forms of PCD, releases a large number of damage-associated molecular patterns (DAMPs), which activate innate immunity to form an inflammatory cascade and further aggravates tissue damage. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. In the future, new biomarkers and multi-target intervention strategies should be developed based on PANoptosis, which is expected to open up a new path for the prevention and treatment of CaOx-induced kidney injury."

It reflects the coordinated involvement of apoptosis, pyroptosis, and necroptosis, usually through the PANoptosome in a shared pathological environment. This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. Neural tissue is particularly sensitive to oxidative stress, mitochondrial dysfunction, immune-mediated inflammation, and blood-brain barrier disruption. These pathological changes are common in many forms of neural injury. Therefore, abnormal PANoptosis activation may provide a common mechanism linking different types of nervous system damage. This review summarizes the historical evolution, molecular mechanisms, disease-related roles, and intervention strategies of PANoptosis in neurological disorders. It focuses on PANoptosome assembly and key mechanistic nodes, including NOD-like receptor family pyrin domain-containing 3 (NLRP3), caspase-8, the receptor-interacting serine/threonine protein kinase 1 (RIPK1)/receptor-interacting serine/threonine protein kinase 3 (RIPK3)/mixed lineage kinase domain-like protein (MLKL) axis, gasdermin D (GSDMD), and Ninjurin 1 (NINJ1).

While metabolic reprogramming is linked to immune evasion, the precise mechanistic orchestration remains unclear. Here, utilizing single-cell transcriptomics and quantitative lactylome profiling, we show that elevated tumor lactate drives resistance by broadly suppressing PANoptosis. Mechanistically, under chemotherapeutic stress, the Lysine acetyltransferase 8 (KAT8) catalyzes the specific lactylation of the inner mitochondrial membrane ADP/ATP translocator 2 (ANT2)\u00a0at K92. Lactylated ANT2 recruits the phosphoglycerate mutase 5\u00a0(PGAM5) to dephosphorylate Cyclophilin D (CypD). This cascade restricts mitochondrial permeability transition pore (mPTP) opening, preserving mitochondrial homeostasis and averting immunogenic cell death. Crucially, a cell-penetrating competitive peptide targeting the KAT8-ANT2 interface effectively uncouples this metabolic lock, re-sensitizing TNBC tumors to cytotoxic stress and restoring chemo-immunotherapy efficacy in vivo. Our findings unveil a profound mechanistic link between the Warburg effect and mitochondrial homeostasis, establishing KAT8-mediated ANT2 lactylation as a targetable vulnerability to improve chemo-immunotherapy efficacy."

However, the mechanism of myocardial PANoptosis in myocardial ischemia-reperfusion (MI/R) remains unclear. Allicin is a promising drug for MI/R treatment, and the targets for myocardial PANoptosis remain to be explored. This study aims to clarify the mechanism of myocardial PANoptosis during MI/R and therapeutic targets of allicin. Sprague-Dawley rats were used to establish MI/R models. Allicin (3.6\u202fmg/kg) was injected via the tail vein 5\u202fmin before reperfusion. Myocardial damage (cardiac function, structure, cTnT, CK-MB and apoptosis), PANoptosome components (RIPK1/3, caspase-8, ASC and NLRP3), PANoptosis indicators (MLKL, GSDMD, IL-1\u03b2/18 and caspase-3) were assessed to evaluate the cardioprotective effects of allicin. Subsequently, the potential signaling pathway related to PANoptosis and therapeutic targets of allicin were screened through transcriptomic analysis, and TLR4 signaling was selected for verification. Then, H9C2 cells were used to establish an oxygen-glucose deprivation/reperfusion (OGD/R) model. The TLR4 inhibitor TAK-242, agonist RS09, and allicin were used to clarify the pathological role of TLR4 in myocardial PANoptosis and the therapeutic target of allicin by measuring the indicators of myocardial damage, PANoptosis and TLR4 expression. In vivo experiments revealed that allicin alleviated MI/R injury and reduced both myocardial PANoptosome components and PANoptosis. Based on transcriptomic analysis and published studies, the TLR4 signaling pathway was selected to verify the pathological role in PANoptosis and the therapeutic effects of allicin. In vitro experiments demonstrated that TLR4 activation further aggravated OGD/R-induced PANoptosis and increased TLR4 expression. Conversely, both allicin and the TLR4 inhibitor suppressed myocardial PANoptosis and TLR4 expression. Allicin can reduce myocardial PANoptosis and ameliorate MI/R injury by inhibiting TLR4 activation. These findings provide a new target and strategy for the treatment of MI/R injury."

Increasing evidence indicates that regulated cell death (RCD) can act as an upstream amplifier in selected autoimmune settings, while in other settings it may mainly report downstream collateral injury caused by cytotoxic lymphocytes, immune complexes, complement activation, or tissue hypoxia. Accordingly, this review distinguishes causal death execution from associative pathway signatures and highlights the types of longitudinal, cell-type-resolved, and perturbational evidence needed to make that distinction. We summarize how apoptosis, necroptosis, pyroptosis, and ferroptosis operate as an interlocking network in autoimmune microenvironments, frequently co-existing as context-dependent mixed-death states driven by shared triggers such as cytokines, PRR ligands, and oxidative stress, and governed by decision hubs including RIPK1 and caspase-8. We highlight integrated concepts such as PANoptosis to explain pathway convergence and compensatory switching into parallel lytic branches when a single node is constrained. The review further connects mechanistic insights to translational priorities, emphasizing biomarker strategies that report pathway engagement, targeted modulation of executors or upstream sensing and cytokine circuits, and lesion-localized delivery approaches to improve the therapeutic window. Finally, we outline key gaps that must be addressed to enable precision interventions, including spatial and cell-type resolved validation of death programs, longitudinal profiling across flare-remission trajectories, and harmonized composite panels capable of capturing mixed-death dynamics in heterogeneous AIDs."

While these responses can be beneficial in host defense, aberrant activation of inflammatory, lytic cell death pathways can be pathogenic. Emerging evidence suggests that cellular metabolic disruption can promote inflammatory cell death, but the mechanistic connections between these processes are not well understood, limiting our ability to identify regulatory nodes that can be therapeutically targeted. Here, we found that intracellular levels of the metabolic cofactor nicotinamide adenine dinucleotide (NAD+) were depleted in response to cell death triggers that drive pyroptosis, necroptosis, PANoptosis, and ferroptosis. However, restoring NAD+ inhibited PANoptosis but not the other forms of cell death. Mechanistically, NAD+ restoration reduced the expression of PANoptotic sensors or regulators, including the transcription factor IRF1, a critical factor for innate immune sensor priming in PANoptosis. Our findings thereby suggest that NAD+ depletion is an early cell death signaling event and that restoring NAD+ levels specifically blocks PANoptosis by suppressing priming. Hence, targeting NAD+ metabolism represents a potential therapeutic strategy for infectious and inflammatory diseases associated with dysregulated PANoptosis."

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma."

While pharmacological, psychological, and physiotherapeutic approaches have been applied, including whole-body vibration (WBV), synaptic-level mechanisms of WBV remain largely unexplored. Here, we assessed the post-SCI pain-associated behavior index (PAB, based on established behavioral criteria) and compared synapse counts (SYN+, VGLUT1+, ChAT+, VGAT+), CGRP+- and SER+-structures, as well as astrocytic and microglial populations in the lumbar dorsal horn following thoracic SCI in WBV-treated and untreated rats. Animals received WBV from postoperative week 3 to 12, and outcomes were compared with non-treated controls. PAB was consistently reduced in WBV-treated animals. STED-microscopy quantification showed that WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals, as well as the number of SER\u2009+\u2009fibers.

Our data indicate that the WBV-induced frequent (15-30\u2005Hz) muscle contractions and proprioceptive impulses contribute to spasticity modulation (via VGAT-related mechanisms) and attenuation of post-SCI hyperalgesia (CGRP-associated). Together with the reduced astro- and microglia amounts, the described synaptic alterations are considered essential prerequisites for better motor recovery. These findings provide preclinical evidence for the functional benefits of WBV in an animal SCI model and warrant further investigations to determine mechanisms underpinning this non-invasive, low-cost and easily applicable rehabilitation approach."

We previously showed that intensified interaction between mutant ATXN1 and Capicua (CIC) drives SCA1 pathogenesis in the cerebellum, whereas ATXN1 loss augments amyloid \u03b2 production in the hippocampus and cortex. CIC, however, forms a complex with ATXN1 and its paralog, Ataxin-1-like (ATXN1L), yet knockout of either yields completely different phenotypes. To determine whether this could be due to CIC having two isoforms, we generated mice bearing either the long (CIC-L) or short (CIC-S) isoform. Loss of CIC-L led to cognitive deficits, whereas loss of CIC-S caused early postnatal lethality, phenocopying ATXN1 and ATXN1L knockout mice, respectively. Furthermore, CIC-L preferentially interacts with ATXN1, and CIC-S with ATXN1L.

Neuronal apoptosis constitutes a critical pathological event leading to neurological dysfunctions, which is further exacerbated by oxidative stress following SCI. Esculentoside A (EsA), a bioactive saponin isolated from Phytolaca esculenta, exhibits neuroprotective potential in our preliminary studies. However, whether EsA attenuates oxidative stress and neuronal apoptosis in SCI remains unclear. The current study aimed to investigate the protective potential of EsA against oxidative stress and neuronal apoptosis following SCI, and to elucidate the associated molecular mechanisms. SCI was modeled in rats via contusion using the PSI-IH 0400 Striker impactor, and rats were treated intraperitoneally with 10 mg/kg EsA once daily. The Basso, Beattie, and Bresnahan (BBB) scale, grid walk analysis, and footprint test were adopted to evaluate motor function dynamically. Histopathological alterations in spinal cord tissue were examined by Hematoxylin-eosin (HE), Luxol Fast Blue (LFB), and Nissl staining. Oxidative stress markers, including hydrogen peroxide (H2O2) and malondialdehyde (MDA), along with antioxidant enzymes glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD), were quantified in spinal cord homogenates using commercial assay kits. Western blot, immunofluorescence staining, and molecular docking were employed to investigate the underlying mechanisms. EsA significantly improved motor function and reduced histopathological damage in SCI rats. This neuroprotective effect was accompanied by a significant improvement in oxidative stress biomarkers and neuronal apoptosis in the injured spinal cord, coinciding with activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway.

The degenerative disc's harsh microenvironment promotes nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) death and hinders self repair. Mesencephalic astrocyte-derived neurotrophic factor (MANF), an atypical neurotrophic factor, has protective effects in degenerative diseases. However, its role in IDD is unclear. Assessment of MANF expression was conducted in both human nucleus pulposus tissues and a rat IVD puncture model. An in vitro model of degeneration was established by acid treatment of NP-MSCs, and the functional role of MANF was explored through its knockdown and overexpression. RNA sequencing was employed to identify downstream targets. The therapeutic potential of MANF-overexpressing NP-MSCs was evaluated in a rat puncture model. MANF expression was markedly downregulated in degenerated IVD tissues from both human patients and rat models. Correspondingly, in vitro experiments demonstrated that MANF knockdown exacerbated, while its overexpression mitigated, acid-induced apoptosis of NP-MSCs. Mechanistically, MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity, as demonstrated by the complete abolition of this protection upon treatment with the MAM uncoupler FATE1. Transcriptomic analysis and subsequent validation identified receptor expression-enhancing protein 1 (REEP1) as a critical downstream effector through which MANF safeguards MAM integrity. We further elucidated that MANF upregulates REEP1 expression by directly inhibiting miR-33b-5p. In vivo, transplantation of MANF-overexpressing NP-MSCs effectively attenuated IDD in a rat model. MANF protected NP-MSCs from acidosis by sustaining MAM integrity via the MiR-33b-5p/REEP1 axis. These findings reveal MANF's mechanism and therapeutic potential for IDD."

Botulinum neurotoxin type A (BoNT/A) has shown anti-inflammatory and neuroprotective effects in acute SCI, but its potential in the chronic phase remains unclear. This study investigates whether combining BoNT/A with electrical muscle stimulation (EMS) enhances recovery in chronic SCI. Adult mice with severe thoracic SCI (paraplegic) underwent EMS (30\u00a0min/d for 10 non-consecutive days starting 3 d post-injury) or no stimulation. Fifteen days after SCI, animals received a single intrathecal injection of BoNT/A (15\u00a0pg/5\u00a0\u03bcl) or saline. Functional recovery was assessed up to 60 d as well as in moderate and mild SCI mice. NeP onset and maintenance were evaluated. Spinal cord tissue was analysed for astrocytic and microglial morphology, neuronal and oligodendroglial survival, myelin protein expression, and in vitro effects on oligodendrocyte precursor cells (OPCs). The phenotype of hindlimb muscles was evaluated through morphological and gene expression analyses. EMS was able to counteract muscle atrophy and fibrosis, and when combined with BoNT/A, also denervation. Moreover, the combination restored hindlimb motor function in chronic SCI, whereas BoNT/A or EMS alone were ineffective. NeP, a common comorbidity associated with SCI, was mitigated by BoNT/A treatment even when administered in the chronic phase. BoNT/A reduced astrocytic hypertrophy and excitatory synapse association and was associated with a morphology-based redistribution of microglial profiles toward a resting-like classification, decreased apoptosis, and increased neuronal and oligodendroglial survival. Myelin basic protein (MBP) expression was significantly elevated in vivo. In vitro, BoNT/A promoted OPC differentiation into myelinating oligodendrocytes, increased process complexity, and upregulated MBP, galactocerebroside C, proteolipid protein, and myelin oligodendrocyte glycoprotein under both proliferative and differentiating conditions. Cleaved synaptosomal-associated protein 25 colocalization with OPC confirmed direct BoNT/A internalization and activity. BoNT/A exerts neuroprotective effects in chronic SCI by reducing neuroinflammation and supporting neuronal and oligodendroglial preservation. When combined with EMS, it also promotes remyelination and improves muscle homeostasis, suggesting that early stimulation creates a permissive environment for recovery. These findings support the clinical evaluation of BoNT/A as a therapeutic strategy for chronic SCI."

LD function is tightly intertwined with liquid-liquid phase separation (LLPS) and epigenetic remodeling, bridging cellular metabolism to gene expression and cell fate control. LD biogenesis relies on ER lipid structures, phase-separated protein assemblies and lipid regulatory proteins. Via contacts with multiple organelles, LDs regulate lipid catabolism, ferroptosis, inflammation and chromatin accessibility, while their metabolites directly reshape epigenetic modifications and transcription. LLPS-driven biomolecular condensates further coordinate LD-linked metabolic and stress signaling. Dysregulated LD remodeling mediates metabolic flexibility, immune escape and drug resistance in obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), neurodegeneration, viral infection and cancer. This review summarizes progress in LD biogenesis and metabolism, dissects mechanistic crosstalk between LDs, LLPS and epigenetic control, and outlines LD-driven pathogenic reprogramming across human disorders. We also discuss therapeutic approaches targeting LD and LLPS pathways. Despite promising translational prospects, unresolved mechanistic and clinical hurdles persist.

These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors."

However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse."

Necroptosis, a caspase-independent inflammatory form of programmed cell death, has emerged as a critical driver of the pathogenesis of cardiovascular disorders, neurodegenerative diseases, and cancer. Concurrently, our understanding of mitochondrial biology has undergone a paradigm shift: mitochondria are no longer viewed merely as bioenergetic powerhouses, but as dynamic signalling hubs that orchestrate metabolic reprogramming, cellular homeostasis, and ultimate cell fate decisions. In this regard, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This review delineates the mechanistic interplay between necroptosis and mitochondrial dysfunction and systematically analyzes the key molecular mediators and pathological pathways through which mitochondrial dysregulation drives necroptotic activation. Furthermore, this review identifies actionable therapeutic targets and translational strategies for modulating necroptosis in related diseases."

The core pathological event of CaOx crystals is the damage of renal tubular epithelial cells (RTECs). Recent studies have shown that CaOx crystals can induce a variety of programmed cell death (PCD) pathways, such as apoptosis, pyroptosis, necroptosis, and ferroptosis, in RTECs at the same time, and there are complex compensations and crosstalk between these death pathways, resulting in the limited efficacy of a single targeting strategy. Therefore, exploring the mechanisms that can integrate the regulation of multiple cell death pathways has become an important direction in this field. PANoptosis is an inflammatory PCD mode driven by the PANoptosome complex, which synchronously triggers the characteristic events of three death pathways in the same cell through the cooperative integration of the core molecular components of pyroptosis, apoptosis, and necroptosis. In this process, cysteinyl aspartate-specific proteinase-8 (Caspase-8) and receptor-interacting serine/threonine kinase 3 (RIPK3), as the core components of the PANoptosome, jointly determine whether the cell goes to a single programmed death or an integrated PANoptosis. The limited studies' evidence supports that CaOx crystals induce concurrent activation of apoptosis, pyroptosis, and necroptosis, suggesting the possibility of PANoptosis in CaOx\u2011induced kidney injury. At the same time, the rupture of the cell membrane caused by PANoptosis, similar to other forms of PCD, releases a large number of damage-associated molecular patterns (DAMPs), which activate innate immunity to form an inflammatory cascade and further aggravates tissue damage. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. In the future, new biomarkers and multi-target intervention strategies should be developed based on PANoptosis, which is expected to open up a new path for the prevention and treatment of CaOx-induced kidney injury."

This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. Neural tissue is particularly sensitive to oxidative stress, mitochondrial dysfunction, immune-mediated inflammation, and blood-brain barrier disruption.

While metabolic reprogramming is linked to immune evasion, the precise mechanistic orchestration remains unclear. Here, utilizing single-cell transcriptomics and quantitative lactylome profiling, we show that elevated tumor lactate drives resistance by broadly suppressing PANoptosis. Mechanistically, under chemotherapeutic stress, the Lysine acetyltransferase 8 (KAT8) catalyzes the specific lactylation of the inner mitochondrial membrane ADP/ATP translocator 2 (ANT2)\u00a0at K92. Lactylated ANT2 recruits the phosphoglycerate mutase 5\u00a0(PGAM5) to dephosphorylate Cyclophilin D (CypD). This cascade restricts mitochondrial permeability transition pore (mPTP) opening, preserving mitochondrial homeostasis and averting immunogenic cell death. Crucially, a cell-penetrating competitive peptide targeting the KAT8-ANT2 interface effectively uncouples this metabolic lock, re-sensitizing TNBC tumors to cytotoxic stress and restoring chemo-immunotherapy efficacy in vivo. Our findings unveil a profound mechanistic link between the Warburg effect and mitochondrial homeostasis, establishing KAT8-mediated ANT2 lactylation as a targetable vulnerability to improve chemo-immunotherapy efficacy."

However, the mechanism of myocardial PANoptosis in myocardial ischemia-reperfusion (MI/R) remains unclear. Allicin is a promising drug for MI/R treatment, and the targets for myocardial PANoptosis remain to be explored. This study aims to clarify the mechanism of myocardial PANoptosis during MI/R and therapeutic targets of allicin. Sprague-Dawley rats were used to establish MI/R models. Allicin (3.6\u202fmg/kg) was injected via the tail vein 5\u202fmin before reperfusion. Myocardial damage (cardiac function, structure, cTnT, CK-MB and apoptosis), PANoptosome components (RIPK1/3, caspase-8, ASC and NLRP3), PANoptosis indicators (MLKL, GSDMD, IL-1\u03b2/18 and caspase-3) were assessed to evaluate the cardioprotective effects of allicin. Subsequently, the potential signaling pathway related to PANoptosis and therapeutic targets of allicin were screened through transcriptomic analysis, and TLR4 signaling was selected for verification. Then, H9C2 cells were used to establish an oxygen-glucose deprivation/reperfusion (OGD/R) model. The TLR4 inhibitor TAK-242, agonist RS09, and allicin were used to clarify the pathological role of TLR4 in myocardial PANoptosis and the therapeutic target of allicin by measuring the indicators of myocardial damage, PANoptosis and TLR4 expression. In vivo experiments revealed that allicin alleviated MI/R injury and reduced both myocardial PANoptosome components and PANoptosis. Based on transcriptomic analysis and published studies, the TLR4 signaling pathway was selected to verify the pathological role in PANoptosis and the therapeutic effects of allicin. In vitro experiments demonstrated that TLR4 activation further aggravated OGD/R-induced PANoptosis and increased TLR4 expression. Conversely, both allicin and the TLR4 inhibitor suppressed myocardial PANoptosis and TLR4 expression. Allicin can reduce myocardial PANoptosis and ameliorate MI/R injury by inhibiting TLR4 activation. These findings provide a new target and strategy for the treatment of MI/R injury."

Increasing evidence indicates that regulated cell death (RCD) can act as an upstream amplifier in selected autoimmune settings, while in other settings it may mainly report downstream collateral injury caused by cytotoxic lymphocytes, immune complexes, complement activation, or tissue hypoxia. Accordingly, this review distinguishes causal death execution from associative pathway signatures and highlights the types of longitudinal, cell-type-resolved, and perturbational evidence needed to make that distinction.

We highlight integrated concepts such as PANoptosis to explain pathway convergence and compensatory switching into parallel lytic branches when a single node is constrained. The review further connects mechanistic insights to translational priorities, emphasizing biomarker strategies that report pathway engagement, targeted modulation of executors or upstream sensing and cytokine circuits, and lesion-localized delivery approaches to improve the therapeutic window. Finally, we outline key gaps that must be addressed to enable precision interventions, including spatial and cell-type resolved validation of death programs, longitudinal profiling across flare-remission trajectories, and harmonized composite panels capable of capturing mixed-death dynamics in heterogeneous AIDs."

While these responses can be beneficial in host defense, aberrant activation of inflammatory, lytic cell death pathways can be pathogenic. Emerging evidence suggests that cellular metabolic disruption can promote inflammatory cell death, but the mechanistic connections between these processes are not well understood, limiting our ability to identify regulatory nodes that can be therapeutically targeted. Here, we found that intracellular levels of the metabolic cofactor nicotinamide adenine dinucleotide (NAD+) were depleted in response to cell death triggers that drive pyroptosis, necroptosis, PANoptosis, and ferroptosis. However, restoring NAD+ inhibited PANoptosis but not the other forms of cell death. Mechanistically, NAD+ restoration reduced the expression of PANoptotic sensors or regulators, including the transcription factor IRF1, a critical factor for innate immune sensor priming in PANoptosis. Our findings thereby suggest that NAD+ depletion is an early cell death signaling event and that restoring NAD+ levels specifically blocks PANoptosis by suppressing priming. Hence, targeting NAD+ metabolism represents a potential therapeutic strategy for infectious and inflammatory diseases associated with dysregulated PANoptosis."

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma."

While pharmacological, psychological, and physiotherapeutic approaches have been applied, including whole-body vibration (WBV), synaptic-level mechanisms of WBV remain largely unexplored. Here, we assessed the post-SCI pain-associated behavior index (PAB, based on established behavioral criteria) and compared synapse counts (SYN+, VGLUT1+, ChAT+, VGAT+), CGRP+- and SER+-structures, as well as astrocytic and microglial populations in the lumbar dorsal horn following thoracic SCI in WBV-treated and untreated rats. Animals received WBV from postoperative week 3 to 12, and outcomes were compared with non-treated controls. PAB was consistently reduced in WBV-treated animals. STED-microscopy quantification showed that WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals, as well as the number of SER\u2009+\u2009fibers.

Our data indicate that the WBV-induced frequent (15-30\u2005Hz) muscle contractions and proprioceptive impulses contribute to spasticity modulation (via VGAT-related mechanisms) and attenuation of post-SCI hyperalgesia (CGRP-associated). Together with the reduced astro- and microglia amounts, the described synaptic alterations are considered essential prerequisites for better motor recovery. These findings provide preclinical evidence for the functional benefits of WBV in an animal SCI model and warrant further investigations to determine mechanisms underpinning this non-invasive, low-cost and easily applicable rehabilitation approach."

Spinocerebellar ataxia type 1 (SCA1) primarily affects the cerebellum, though Ataxin-1 (ATXN1) is widely expressed. We previously showed that intensified interaction between mutant ATXN1 and Capicua (CIC) drives SCA1 pathogenesis in the cerebellum, whereas ATXN1 loss augments amyloid \u03b2 production in the hippocampus and cortex. CIC, however, forms a complex with ATXN1 and its paralog, Ataxin-1-like (ATXN1L), yet knockout of either yields completely different phenotypes. To determine whether this could be due to CIC having two isoforms, we generated mice bearing either the long (CIC-L) or short (CIC-S) isoform. Loss of CIC-L led to cognitive deficits, whereas loss of CIC-S caused early postnatal lethality, phenocopying ATXN1 and ATXN1L knockout mice, respectively. Furthermore, CIC-L preferentially interacts with ATXN1, and CIC-S with ATXN1L. Our data underscore the importance of isoform-paralog interplay in studying regional vulnerability in neurodegenerative diseases."

The degenerative disc's harsh microenvironment promotes nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) death and hinders self repair. Mesencephalic astrocyte-derived neurotrophic factor (MANF), an atypical neurotrophic factor, has protective effects in degenerative diseases. However, its role in IDD is unclear. Assessment of MANF expression was conducted in both human nucleus pulposus tissues and a rat IVD puncture model. An in vitro model of degeneration was established by acid treatment of NP-MSCs, and the functional role of MANF was explored through its knockdown and overexpression. RNA sequencing was employed to identify downstream targets. The therapeutic potential of MANF-overexpressing NP-MSCs was evaluated in a rat puncture model. MANF expression was markedly downregulated in degenerated IVD tissues from both human patients and rat models. Correspondingly, in vitro experiments demonstrated that MANF knockdown exacerbated, while its overexpression mitigated, acid-induced apoptosis of NP-MSCs. Mechanistically, MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity, as demonstrated by the complete abolition of this protection upon treatment with the MAM uncoupler FATE1. Transcriptomic analysis and subsequent validation identified receptor expression-enhancing protein 1 (REEP1) as a critical downstream effector through which MANF safeguards MAM integrity. We further elucidated that MANF upregulates REEP1 expression by directly inhibiting miR-33b-5p. In vivo, transplantation of MANF-overexpressing NP-MSCs effectively attenuated IDD in a rat model. MANF protected NP-MSCs from acidosis by sustaining MAM integrity via the MiR-33b-5p/REEP1 axis. These findings reveal MANF's mechanism and therapeutic potential for IDD."

Botulinum neurotoxin type A (BoNT/A) has shown anti-inflammatory and neuroprotective effects in acute SCI, but its potential in the chronic phase remains unclear. This study investigates whether combining BoNT/A with electrical muscle stimulation (EMS) enhances recovery in chronic SCI. Adult mice with severe thoracic SCI (paraplegic) underwent EMS (30\u00a0min/d for 10 non-consecutive days starting 3 d post-injury) or no stimulation. Fifteen days after SCI, animals received a single intrathecal injection of BoNT/A (15\u00a0pg/5\u00a0\u03bcl) or saline. Functional recovery was assessed up to 60 d as well as in moderate and mild SCI mice. NeP onset and maintenance were evaluated. Spinal cord tissue was analysed for astrocytic and microglial morphology, neuronal and oligodendroglial survival, myelin protein expression, and in vitro effects on oligodendrocyte precursor cells (OPCs). The phenotype of hindlimb muscles was evaluated through morphological and gene expression analyses. EMS was able to counteract muscle atrophy and fibrosis, and when combined with BoNT/A, also denervation. Moreover, the combination restored hindlimb motor function in chronic SCI, whereas BoNT/A or EMS alone were ineffective. NeP, a common comorbidity associated with SCI, was mitigated by BoNT/A treatment even when administered in the chronic phase. BoNT/A reduced astrocytic hypertrophy and excitatory synapse association and was associated with a morphology-based redistribution of microglial profiles toward a resting-like classification, decreased apoptosis, and increased neuronal and oligodendroglial survival. Myelin basic protein (MBP) expression was significantly elevated in vivo. In vitro, BoNT/A promoted OPC differentiation into myelinating oligodendrocytes, increased process complexity, and upregulated MBP, galactocerebroside C, proteolipid protein, and myelin oligodendrocyte glycoprotein under both proliferative and differentiating conditions. Cleaved synaptosomal-associated protein 25 colocalization with OPC confirmed direct BoNT/A internalization and activity. BoNT/A exerts neuroprotective effects in chronic SCI by reducing neuroinflammation and supporting neuronal and oligodendroglial preservation. When combined with EMS, it also promotes remyelination and improves muscle homeostasis, suggesting that early stimulation creates a permissive environment for recovery. These findings support the clinical evaluation of BoNT/A as a therapeutic strategy for chronic SCI."

Mounting evidence redefines LDs as dynamic metabolic signaling hubs orchestrating cellular stress adaptation, with multifaceted roles in organelle crosstalk, metabolic reprogramming, redox balance and immune signaling. LD function is tightly intertwined with liquid-liquid phase separation (LLPS) and epigenetic remodeling, bridging cellular metabolism to gene expression and cell fate control. LD biogenesis relies on ER lipid structures, phase-separated protein assemblies and lipid regulatory proteins. Via contacts with multiple organelles, LDs regulate lipid catabolism, ferroptosis, inflammation and chromatin accessibility, while their metabolites directly reshape epigenetic modifications and transcription. LLPS-driven biomolecular condensates further coordinate LD-linked metabolic and stress signaling. Dysregulated LD remodeling mediates metabolic flexibility, immune escape and drug resistance in obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), neurodegeneration, viral infection and cancer. This review summarizes progress in LD biogenesis and metabolism, dissects mechanistic crosstalk between LDs, LLPS and epigenetic control, and outlines LD-driven pathogenic reprogramming across human disorders. We also discuss therapeutic approaches targeting LD and LLPS pathways. Despite promising translational prospects, unresolved mechanistic and clinical hurdles persist.

These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors."

However, the mechanism of myocardial PANoptosis in myocardial ischemia-reperfusion (MI/R) remains unclear. Allicin is a promising drug for MI/R treatment, and the targets for myocardial PANoptosis remain to be explored. This study aims to clarify the mechanism of myocardial PANoptosis during MI/R and therapeutic targets of allicin. Sprague-Dawley rats were used to establish MI/R models. Allicin (3.6\u202fmg/kg) was injected via the tail vein 5\u202fmin before reperfusion. Myocardial damage (cardiac function, structure, cTnT, CK-MB and apoptosis), PANoptosome components (RIPK1/3, caspase-8, ASC and NLRP3), PANoptosis indicators (MLKL, GSDMD, IL-1\u03b2/18 and caspase-3) were assessed to evaluate the cardioprotective effects of allicin. Subsequently, the potential signaling pathway related to PANoptosis and therapeutic targets of allicin were screened through transcriptomic analysis, and TLR4 signaling was selected for verification. Then, H9C2 cells were used to establish an oxygen-glucose deprivation/reperfusion (OGD/R) model. The TLR4 inhibitor TAK-242, agonist RS09, and allicin were used to clarify the pathological role of TLR4 in myocardial PANoptosis and the therapeutic target of allicin by measuring the indicators of myocardial damage, PANoptosis and TLR4 expression. In vivo experiments revealed that allicin alleviated MI/R injury and reduced both myocardial PANoptosome components and PANoptosis. Based on transcriptomic analysis and published studies, the TLR4 signaling pathway was selected to verify the pathological role in PANoptosis and the therapeutic effects of allicin. In vitro experiments demonstrated that TLR4 activation further aggravated OGD/R-induced PANoptosis and increased TLR4 expression. Conversely, both allicin and the TLR4 inhibitor suppressed myocardial PANoptosis and TLR4 expression. Allicin can reduce myocardial PANoptosis and ameliorate MI/R injury by inhibiting TLR4 activation. These findings provide a new target and strategy for the treatment of MI/R injury."

Its physiological and pathological roles span multiple medical domains, including oncology, neurodegeneration, and cardiovascular disease. Modulation of ferroptotic pathways, through iron homeostasis, antioxidant defense (e.g., GPX4/System Xc- axis), and lipid metabolism, offers a significant therapeutic frontier, particularly in overcoming treatment resistance.\n\n### [INTRODUCTION & JUSTIFICATION]\nFerroptosis is an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation. Emerging evidence indicates that susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets. Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **The Driver-Amplifier Concept:** In drug-induced cardiotoxicity (specifically Doxorubicin), ferroptosis is being re-evaluated not merely as an initiator, but potentially as a downstream amplifier of cardiac damage.\n*   **Cross-Organelle Coordination:** Sensitivity is not just cytoplasmic; mitochondria, lysosomes, and lipid droplets act as integrated rheostats for cell death execution.\n*   **Transcriptional Regulation of Lipid Metabolism:** Histone acylation (H3K18la) directly modulates ACSL4 to trigger ferroptosis in myocardial ischemia-reperfusion scenarios.\n*   **Viral Manipulation:** EBV latency III programs are found to redirect methionine metabolism toward redox defense, specifically inducing transsulfuration to sustain cysteine and glutathione pools, creating a targetable ferroptotic vulnerability.\n*   **Radiation Synergy:** Ferroptosis induction is a key driver of the synergistic efficacy observed in combined radiotherapy and KRAS inhibition in pancreatic cancer models.\n*   **Immune/Ferroptosis Crosstalk:** Ferroptosis-related transcriptional activities are dynamically activated alongside pyroptosis and necroptosis after spinal cord injury, suggesting a collaborative lytic cell death program.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While current evidence supports a strong association between CD14 expression, lytic cell death, and myeloid inflammatory responses, the direct causal role of CD14 in modulating these specific lipid peroxidation-dependent cell death pathways requires functional experimental confirmation.\n\n### [INTRODUCTION & JUSTIFICATION]\nSecondary injury following SCI involves complex, interconnected mechanisms including oxidative stress, inflammation, and programmed cell death. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI. Evidence from related models underscores that rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   CD14 is identified as the most robust candidate hub gene connecting lytic cell death signatures (pyroptosis, necroptosis, ferroptosis) to myeloid inflammatory activation post-SCI.\n*   Ferroptosis in microglia acts as an upstream driver of sustained neuroinflammation, linking iron dyshomeostasis and lipid peroxidation to inflammatory amplification.\n*   Ninjurin1 (NINJ1) functions as a terminal executor of plasma membrane rupture across multiple cell death modes, including ferroptosis and pyroptosis, positioning it as a structural nexus in lytic cell death.\n*   Recent data suggest that PANoptosis\u2014the synergistic activation of pyroptosis, apoptosis, and necroptosis via the PANoptosome\u2014is a major contributor to SCI secondary injury.\n*   Therapeutic modulation via adipose-derived ECM hydrogels loaded with cytokines or antioxidants (e.g., QM complexes) shows promise in suppressing ferroptosis and mitigating SCI-induced neuronal loss.\n*   Specific mechanosensitive channels like Piezo1 in microglia mediate mitochondrial dysfunction and ferroptosis, with their inhibition proving protective against secondary inflammatory damage.\n*   Sphingosine-1-phosphate receptor 2 (S1P2) signaling represents a distinct pathway driving neuronal ferroptosis following contusive SCI.\n*   GADD45A has been identified as a critical regulator that coordinates both ferroptosis and apoptosis via the NF-\u03baB pathway in SCI models.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Recent literature suggests that CD14 serves as a robust candidate hub gene associated with myeloid inflammatory activation and lytic cell death signatures. While direct clinical evidence for CD14 inhibition as a singular PANoptosome-blocking strategy remains in the exploratory phase, the integration of CD14 into the broader framework of lytic cell death regulation provides a compelling mechanistic target to mitigate the progressive neuroinflammatory feed-forward loop.\n\n### [INTRODUCTION & JUSTIFICATION]\nSecondary injury after spinal cord injury (SCI) is a multifaceted pathological process characterized by persistent inflammation, oxidative stress, and multiple forms of programmed cell death (PCD). The literature identifies that lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. Crucially, the discovery that CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures highlights its potential role as a gatekeeper of the inflammatory response. \n\nThe mechanism by which this cell death occurs involves a complex coordination between metabolic and inflammatory pathways. For instance, PLIN2 interacts with the mitochondrial outer membrane protein PGAM5 to regulate lipid droplet-mitochondria contacts. This relationship is critical, as Genetic deletion of Plin2 markedly reduced lipid droplet burden, attenuated neuroinflammation, and promoted neuronal survival and functional recovery in vivo. These metabolic perturbations are not isolated; rather, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This dysfunction facilitates the \"ferroptotic storm,\" described as Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. \n\nFurthermore, the integration of multiple cell death pathways into a unified, inflammatory lytic model\u2014PANoptosis\u2014offers a critical framework for therapeutic intervention. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. The rationale for targeting these pathways in the central nervous system is that This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. As CD14 appears as a primary coordinator of these myeloid-driven lytic signatures, its inhibition may interrupt the cross-talk between ferroptotic lipid signaling and PANoptosome assembly, thereby limiting the secondary inflammatory cascade.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   CD14 acts as an upstream candidate hub gene connecting myeloid activation to the execution of lytic cell death in SCI.\n*   The interaction between PLIN2 and PGAM5 provides a targetable metabolic switch that can mitigate the \"ferroptotic storm\" inherent in secondary injury.\n*   Mitochondrial dysfunction serves as a \"central rheostat\" that synchronizes the execution of necroptosis across different cellular models.\n*   PANoptosis provides a unifying conceptual model to resolve why single-pathway inhibition (e.g., anti-pyroptotic alone) often fails in clinical or complex models.\n*   Metabolic stress, specifically NAD+ depletion, selectively controls the susceptibility of cells to PANoptotic signaling.\n*   Bioactive interventions, such as BoNT/A or exercise-derived exosomes, demonstrate that structural and functional recovery requires simultaneous multi-axis modulation of inflammatory and apoptotic markers.\n*   The complexity of protein-ligand interactions, such as NADH recognition, highlights the necessity for precise, structural-based inhibitor design to manage neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets.\nFerroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms.\nWe found that iron accumulates with aging, but surprisingly decreases with AIE.\nIron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production.\nWithin the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis\nCollectively, these findings suggest that SYNCRIP is a key regulator of GBM progression by maintaining metabolic homeostasis and ferroptosis resistance, highlighting SYNCRIP as a potential therapeutic target in GBM.\nMethionine restriction elevated LCL lipid reactive oxygen species and triggered ferroptosis.\nThese convergent mechanisms position ZDHHC-mediated S-palmitoylation as a context-dependent regulator of tumor progression, therapy response, ferroptosis sensitivity, and immune phenotype.\nMechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment.\nMechanistically, H3K18la was enriched in the promoter region of ACSL4 to facilitate its transcriptional activation, and knockdown of ACSL4 markedly reversed OGD/R-triggered cardiomyocyte ferroptosis.\nPyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time.\nRecent bursts (2024\u20112025) highlight \"pyroptosis\" and \"ferroptosis\" as emerging frontiers.\nInduced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways\nRRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis.\nKRAS G12D mutations in lung epithelium drive proliferation of resident, embryonically-derived alveolar macrophages, which then promote tumor cell proliferation and protection from ferroptosis, leading to tumor progression.\nThis review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways.\nIntriguingly, the addition of a ferroptosis inhibitor, liproxstatin-1, to the combination therapy significantly abrogated the in vivo synergism between SBRT and KRAS inhibition, suggesting that treatment-induced ferroptosis at least partially drives the synergistic efficacy of this combination strategy.\nApart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity.\nFerroptosis is an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation.\nEmerging evidence indicates that susceptibility to

persisting over time.\nIntegrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index.\nEnrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways.\nHowever, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI.\nRather than being

Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. The present narrative review summarizes current evidence on ferroptosis-mediated sensitization mechanisms in combination therapy for HCC, focusing on core regulatory networks, including glutathione peroxidase 4, System Xc- and iron metabolism pathways, and their interactions with key signaling pathways, such as activating transcription factor 4/signal transducer and activator of transcription 3, p53 and Wnt/\u03b2-catenin. The current review also discusses the synergistic effects and molecular mechanisms of ferroptosis inducers combined with targeted therapy, chemotherapy and immunotherapy. Furthermore, the potential value of ferroptosis-related biomarkers for predicting treatment response and prognosis is evaluated, and unresolved mechanistic questions and barriers to clinical translation are highlighted. Finally, the present review outlines future research directions, including the development of targeted nanodelivery systems and biomarker-based clinical trials, to support more precise ferroptosis-based combination strategies for HCC."

Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis, cholesterol and phospholipid remodeling that impacts membrane integrity and lipid rafts, lipid droplet-mediated buffering of metabolic stress, fatty acid oxidation-dependent energy supply, and sphingolipid-regulated apoptosis. This review delineates pre-existing tumor lipid programs from IR-induced adaptive responses, highlighting that their contributions to radiosensitivity or radioresistance are contingent upon tumor lineage, genetic background, microenvironmental conditions, and treatment context. The coupling of cancer cells with their microenvironment through lipid interactions, encompassing intercellular lipid transfer, nutrient competition, paracrine lipid mediators, and exosome-mediated signaling, is identified as a central component of radioresistance. In conclusion, therapeutic opportunities are evaluated based on their translational maturity, encompassing a spectrum from mechanistic concepts and preclinical radiosensitization strategies to approaches with emerging clinical significance. This synthesis, focused on radiotherapy, seeks to elucidate how lipid vulnerabilities can be strategically and judiciously exploited to enhance radiation outcomes."

Notably, this study identified that SYNCRIP expression is significantly elevated in glioblastoma (GBM) and is associated with poor prognosis and tumor progression. Mechanistically, SYNCRIP upregulates SIRT1 expression at both the transcriptional and post-transcriptional levels by stabilizing SIRT1 mRNA. Meanwhile, loss of SYNCRIP leads to reduced SIRT1 expression, accumulation of reactive oxygen species (ROS), and induction of ferroptosis. Notably, restoration of SIRT1 rescues cells from ferroptotic cell death, supporting the critical role of SIRT1 in SYNCRIP-mediated ferroptosis resistance. SYNCRIP also enhances hexokinase 2 (HK2) expression through transcriptional activation and internal ribosome entry site (IRES)-mediated translation, thereby promoting glycolytic activity in GBM. Furthermore, depletion of SYNCRIP results in mitochondrial dysfunction and impairs GBM cell migration and invasion by downregulating epithelial-mesenchymal transition (EMT)-associated factors.

Most transformed cells arrest, yet survive when deprived of the essential amino acid methionine. We instead find that EBV transformed lymphoblastoid cell lines (LCLs), which model the EBV latency III program-driven B-cell lymphoproliferative diseases of immunosuppressed hosts, rapidly die upon methionine restriction. Methionine restriction elevated LCL lipid reactive oxygen species and triggered ferroptosis. Whereas methionine restriction hypomethylates the EBV genome and triggers viral reactivation in latency I Burkitt cells by lowering the cellular methylation potential, the LCL latency III program instead redirected methionine toward redox defense, without altering the SAM/SAH ratio. Stable-isotope tracing revealed that latency III strongly induces transsulfuration, synthesizing cysteine de novo to support glutathione pools. The EBV oncoprotein LMP2A, which mimics B-cell receptor signaling, supported newly infected human B cell cystathionine-\u03b2-synthase and cystathionine-\u03b3-lyase expression and methionine dependence, phenocopied by immunoglobulin crosslinking. In vivo , dietary methionine restriction impaired LCL xenograft outgrowth and depleted tumor cystine. Combined methioninase and cyst(e)inase administration blocked both cysteine sources, collapsed tumor glutathione levels, and triggered ferroptosis.

ZDHHC palmitoyltransferases and depalmitoylating enzymes, including acyl-protein thioesterases and palmitoyl-protein thioesterase 1, constitute a dynamic circuitry that governs the localization, stability, and signaling competence of key regulators of tumor growth, metabolic adaptation, and immune phenotype. Here, we synthesize recent structural and chemical biology advances that clarify how human ZDHHC enzymes achieve acyl-chain recognition and substrate engagement. Structural studies show that these enzymes adopt a four-transmembrane, \"tent-like\" fold, in which the helices create a membrane-embedded cavity for acyl-chain accommodation. We also discuss how ankyrin-repeat domains and accessory partners shape substrate recruitment and subcellular localization, and we highlight emerging high-throughput platforms that enable quantitative profiling of isoform- and site-selective modulators. We then discuss how ZDHHC-substrate circuits rewire canonical growth-factor signaling and epithelial-mesenchymal transition programs, metabolic and ferroptotic control nodes, innate immune sensing, and chromatin-linked regulation. These convergent mechanisms position ZDHHC-mediated S-palmitoylation as a context-dependent regulator of tumor progression, therapy response, ferroptosis sensitivity, and immune phenotype. Finally, we outline a translational framework encompassing clinical-stage PPT1 inhibitors, selective ABHD17 blockade, emerging ZDHHC modulators, substrate-competitive strategies targeting checkpoint palmitoylation, and selected comparator approaches affecting Wnt and Hedgehog ligand lipidation. Current evidence positions ZDHHC-mediated S-palmitoylation as a regulatory layer with potential biomarker and therapeutic relevance; however, not all reported ZDHHC-substrate associations carry equivalent evidentiary weight. Mechanisms supported by convergent site-directed, genetic, biochemical, functional, and in vivo evidence should be distinguished from associations inferred mainly from expression profiling, overexpression systems, single-model observations, or broad pharmacological perturbation. Clinical translation remains preliminary and is constrained by isoform selectivity, substrate redundancy, incomplete pharmacodynamic read-outs, and the absence of validated biomarker-guided patient stratification."

Celastrol has recognized anti-inflammatory activity, but its mechanism in RA remains incompletely defined. This study investigated whether the anti-arthritic effect of celastrol is associated, at least in part, with a PTGS2-associated ferroptosis-resistance pathway in FLS. Potential targets of celastrol in RA were identified through integrated bioinformatic analyses. Collagen-induced arthritis (CIA) rats and primary FLS were used to evaluate the effects of celastrol in vivo and in vitro. Joint pathology, inflammatory mediator expression, oxidative stress, iron accumulation, lipid peroxidation, and ferroptosis-related proteins were assessed. Loss- and gain-of-function experiments were performed to examine the functional role of PTGS2. Bioinformatic screening identified PTGS2 as a candidate functional mediator linking celastrol to RA. In CIA rats, celastrol reduced paw swelling, arthritis severity, synovial hyperplasia, inflammatory cell infiltration, and cartilage and bone destruction. In FLS, celastrol suppressed cell proliferation and migration and decreased the expression of pro-inflammatory cytokines. Mechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment. PTGS2 expression was markedly elevated in RA models and was downregulated by celastrol. PTGS2 overexpression attenuated the anti-inflammatory effects of celastrol and reversed several ferroptosis-associated changes, supporting a functional role for PTGS2 in this process. Celastrol alleviates synovial inflammation and experimental arthritis, at least in part, in association with PTGS2 modulation and attenuation of a ferroptosis-resistant phenotype in FLS. To our knowledge, these findings provide experimental evidence linking celastrol, PTGS2-associated regulation, and ferroptosis resistance in RA models."

Reciprocally, MIRI exacerbates hypertension by inducing oxidative stress, inflammatory responses, cardiomyocyte death, fibrosis-associated myocardial remodeling, and RAAS system disruption, forming a vicious feedback cycle. This study aimed to investigate the regulatory role and underlying molecular mechanism of the lactate-related signaling axis in cardiomyocyte ferroptosis during MIRI, and to identify novel potential therapeutic targets for interrupting this detrimental feedback loop. In vivo mouse MIRI models, in vitro cardiomyocyte oxygen\u2012glucose deprivation/reoxygenation (OGD/R) models, and spontaneously hypertensive rat (SHR) models were successfully established. Oxaloacetate and \u03b2-alanine were administered to inhibit lactate production and protein lactylation, respectively. Hematoxylin\u2012eosin (HE) and Masson staining were performed to evaluate myocardial histopathological damage and fibrosis. Immunohistochemistry (IHC) and Western blotting were used to detect the protein expression levels of lysine lactylation (Kla), H3K18la, alanyl-tRNA synthetase 1 (AARS1), and acyl-CoA synthetase long-chain family member 4 (ACSL4). An enzyme-linked immunosorbent assay (ELISA) was adopted to quantify the lactate content and ferroptosis-related marker levels. Transmission electron microscopy (TEM), immunofluorescence staining, and chromatin immunoprecipitation (ChIP) assays were separately utilized to observe the mitochondrial ultrastructure, assess cellular lipid peroxidation, and verify gene promoter enrichment. Lactate, Kla, and H3K18la levels were markedly elevated in the MIRI and OGD/R models, accompanied by severe myocardial injury, fibrosis, and excessive cardiomyocyte ferroptosis. Inhibition of lactate production effectively reduced lactylation levels and mitigated ferroptosis as well as myocardial structural damage. Mechanistically, H3K18la was enriched in the promoter region of ACSL4 to facilitate its transcriptional activation, and knockdown of ACSL4 markedly reversed OGD/R-triggered cardiomyocyte ferroptosis. AARS1 overexpression strengthened lactylation and ACSL4 expression to promote ferroptosis, while its mutant did not. Notably, hypertension aggravated MIRI, promotes further increases in the level of histone lactylation mediated by AARS1, and exacerbates ferroptosis. Pharmacological intervention with \u03b2-alanine blocked the lactate/AARS1/H3K18la/ACSL4 axis and attenuated MIRI-induced myocardial damage. Abnormal lactate accumulation facilitates H3K18la modification via AARS1-dependent regulation, which transcriptionally activates ACSL4 and modulates cardiomyocyte ferroptosis, ultimately contributing to the pathological progression of MIRI. Targeting the lactate/AARS1/H3K18la/ACSL4 regulatory axis is a promising and viable therapeutic strategy for MIRI intervention."

However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures. Key findings were further evaluated using an external human SCI-related cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and published single-cell RNA-seq data. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. External validation in a human SCI-related peripheral blood cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and single-cell reanalysis further supported the upregulation of CD14 and its association with myeloid inflammatory activation and pyroptosis-, necroptosis-, and ferroptosis-related signatures. Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI."

Ferroptosis, an iron-dependent and lipid peroxidation-driven mechanism of regulated cell death, has been associated with neurodevelopment and neurodegeneration, prompting interest in its potential role in ASD. This narrative review consolidates from molecular and clinical studies, animal models, and in vitro systems to assess ferroptosis as a candidate mechanistic pathway, biomarker source, and therapeutic target in ASD. Peripheral transcriptomic analyses reveal differentially expressed ferroptosis-related genes, ferroptosis-based molecular clusters, and immune-activated subtype in children with ASD, facilitating the development of ferroptosis-derived diagnostic and scoring models with modest yet reproducible discrimination. Clinical data associate maladaptive polyunsaturated fatty acid profiles, increased lipid peroxidation products, and adverse docosahexaenoic acid/arachidonic acid ratio with autistic social impairments, aligning with ferroptosis-prone conditions. In rodent models, genetic or pharmacological modulation of DDIT4-PI3K/Akt signaling, Nrf2/GPX4/xCT antioxidant systems, and ferritinophagy mitigates ASD-like social deficits, repetitive behaviors, anxiety-like phenotypes, and liver pathology. Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways, indicating subtype-specific ferroptosis resistance. These findings suggest a complex, context-dependent role of ferroptosis and ferroptosis resistance in ASD, interacting with immune dysregulation, redox imbalance, and peripheral organ involvement. Nevertheless, longitudinal and interventional studies integrating brain, peripheral, and cellular data are required to establish causality, define meaningful ferroptosis-related signatures, and evaluate the safety and efficacy of ferroptosis-modulating interventions."

Ferroptosis, an iron-dependent form of regulated cell death, has emerged as a promising therapeutic avenue. However, the role of Ribonucleotide Reductase M2 (RRM2) in ferroptosis regulation and its relevance to LUAD progression remain incompletely understood. We integrated bulk transcriptomic, proteomic, WGCNA, and single-cell datasets to evaluate the clinical and biological relevance of RRM2 in LUAD. Functional validation was performed using RRM2 knockdown, ferroptosis-inducer sensitivity assays, ferroptosis-related biochemical assays, NRF2/GPX4 pathway analysis, rescue experiments, and xenograft models. RRM2 was significantly upregulated in LUAD tissues and was associated with poor overall survival. Single-cell analysis localized high RRM2 expression to a proliferative tumor cell subpopulation enriched in cell cycle- and immune-related pathways. Functionally, RRM2 knockdown suppressed LUAD cell proliferation and tumor growth and was accompanied by increased ROS, lipid ROS, Fe\u00b2\u207a, and MDA levels and decreased GSH levels. RRM2 depletion also increased ferroptosis-inducer sensitivity, with enhanced erastin and RSL3 sensitivity in A549 cells and clear RSL3 sensitization in PC9 cells. In parallel, RRM2 silencing was associated with reduced NRF2 and GPX4 expression, decreased NRF2 nuclear-to-cytosolic signal intensity, and increased ACSL4 expression. NRF2 overexpression partially restored GPX4 immunofluorescence intensity in RRM2-knockdown cells. Moreover, NRF2 overexpression or Ferr-1 treatment partially reversed the growth-suppressive effects induced by RRM2 deficiency in vitro and in vivo. RRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis. These findings support RRM2 as a candidate prognostic biomarker and a potential therapeutic target in LUAD, while the precise molecular relationship between RRM2 and the NRF2/GPX4 axis warrants further investigation."

An understanding of the specific roles of macrophage subsets in lung tumor initiation and progression could promote new therapeutic approaches for this deadly disease. Here, we show that KRAS G12D mutations in lung epithelium drive proliferation of resident, embryonically-derived alveolar macrophages, which then promote tumor cell proliferation and protection from ferroptosis, leading to tumor progression. Using genetically engineered mouse models of mutant KRAS G12D non-small cell lung cancer 12,13 , we found that alveolar macrophages accumulate by proliferation in response to tumor cell-secreted IL-34, recapitulating events observed in late embryonic lung development. Tumor alveolar macrophages in turn drive IGF-1-dependent tumor cell proliferation. Neutralization or deletion of IL-34 suppresses IGF-1 expression, reduces macrophage and tumor cell proliferation and inhibits tumor progression. High IL34 and IGF1 correlate with poor survival in KRAS G12D/V lung adenocarcinomas and in other solid tumors, indicating that bi-directional proliferative signaling between resident macrophages and tumor cells can drive human lung tumor progression.

Ferroptosis, an iron-dependent, non-apoptotic form of regulated cell death characterized by the lethal accumulation of lipid peroxides, represents a pharmacologically significant vulnerability in cancers that are resistant to apoptosis and tolerant to drugs. The resistance to ferroptosis, induced by the aberrant overexpression of the epigenetic enzyme histone deacetylases (HDACs) and the sustained transcriptional activity of key antiferroptotic targets, particularly GPX4 and SLC7A11, is enforced through epigenetic mechanisms. This review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways. These pathways include the transcriptional silencing of SLC7A11 and subsequent glutathione depletion, disruption of intracellular iron homeostasis via ferroportin downregulation, enhancement of mitochondrial ROS-induced lipid peroxidation, and suppression of the HDAC3-NRF2-GPX4 antiferroptotic axis. The specific roles of HDAC1, HDAC3, and HDAC10 in colorectal, lung, gastric, and hematological cancers are elucidated. Additionally, the review discusses hybrid molecules of HDAC-ferroptosis, combination strategies with GPX4 inhibitors, and immunochemotherapy. Considerations such as isoform selectivity, biomarker development, and clinical translation are addressed, highlighting HDAC inhibitor-mediated ferroptosis sensitization as a promising strategy to overcome drug resistance in cancer.

With mutant KRAS being a key driver, small molecule inhibitors targeting KRAS or pan-RAS (KRASi) have demonstrated exciting preclinical and early clinical anti-tumor efficacy, and the pan-RAS(ON) inhibitor daraxonrasib (RMC-6236) recently achieved Phase 3 clinically meaningful improvements in patient survival compared to chemotherapy. But resistance to RAS/KRAS inhibitor inevitably develops, which limits and compromises the treatment outcome. In this study, we investigated the combination of stereotactic body radiation therapy (SBRT) and KRAS inhibition (MRTX1133 and daraxonrasib) in the treatment of preclinical PDAC models. We found that this combination strategy synergistically suppresses PDAC cell growth in vitro and enhances tumor control while minimizing local recurrence in orthotopically implanted KPC ( LSL-Kras G12D/+ ;Trp53 R172H/+ ;Pdx1-Cre ) murine PDAC tumors in vivo .

However, its associated cardiotoxicity poses a major challenge for its therapeutic use. There are numerous studies exploring the underlying cellular mechanisms behind Dox-induced cardiotoxicity. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity. Under normal physiology, cardiomyocytes maintain a highly regulated iron homeostasis, while the polyunsaturated fatty acid-rich membrane also renders it susceptible to peroxidation, a hallmark of ferroptosis. Dox-induced cardiotoxicity disrupts the coordinated control of iron metabolism, generating reactive oxygen species, propagating lipid peroxidation, and impairing mitochondrial function. Progressive structural damage and functional loss of cardiomyocytes culminate in permanent cardiac cell death. Therefore, targeting regulatory nodes of ferroptosis may be beneficial for ameliorating Dox-induced cytotoxicity. However, it is still not clear whether the ferroptotic process merely acts as an initiator or can further act as an amplifier to upregulate the downstream signaling molecules in this cell death cascade. This review offers an overview of perspectives on the ferroptotic pathway and introduces readers to a novel driver-amplifier concept. See also the graphical abstract(Fig. 1)."

However, the precise mechanism underlying LCD action against hepatocellular carcinoma (HCC) remains unclear, particularly regarding its regulation of cell death. In this study, we comprehensively explored the effects of LCD on HCC cells in vitro and investigated its role and mechanism of action in the induction of PANoptosis. Our results reveal that LCD exhibited potent anti-HCC activities by decreasing cell viability and significantly inhibiting clonogenic survival in HCC cell lines. Our results demonstrate that LCD triggered a substantial accumulation of reactive oxygen species and induced depolarization of the mitochondrial membrane, leading to profound mitochondrial dysfunction. We further confirmed that LCD activated a comprehensive PANoptosis program by synchronously upregulating the expression of apoptotic proteins (Bax, c-CASP3, and c-PARP1), pyroptotic proteins (c-CASP 1 and c-GSDMD), and the phosphorylation of necroptotic executioners (p-MLKL and p-RIPK1). Treatment with the ROS inhibitor (NAC), apoptosis inhibitor (ZVAD), or necroptosis inhibitor (Nec-1) significantly reduced the expression of PANoptosis-related proteins in LCD-treated cells. Furthermore, molecular docking simulations and cellular thermal shift assay (CETSA) assay confirmed the direct and stable binding of LCD to PANoptosis-related proteins. In summary, we show for the first time that LCD exerts favorable anti-HCC activities via the induction of PANoptosis through a ROS-dependent mechanism and potntial direct modulation of core executive proteins. This multi-target action suggests that LCD could be a novel candidate for the management of hepatocellular carcinoma."

Its physiological and pathological roles span multiple medical domains, including oncology, neurodegeneration, and cardiovascular disease. Modulation of ferroptotic pathways, through iron homeostasis, antioxidant defense (e.g., GPX4/System Xc- axis), and lipid metabolism, offers a significant therapeutic frontier, particularly in overcoming treatment resistance.\n\n### [INTRODUCTION & JUSTIFICATION]\nFerroptosis is an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation. Emerging evidence indicates that susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets. Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **The Driver-Amplifier Concept:** In drug-induced cardiotoxicity (specifically Doxorubicin), ferroptosis is being re-evaluated not merely as an initiator, but potentially as a downstream amplifier of cardiac damage.\n*   **Cross-Organelle Coordination:** Sensitivity is not just cytoplasmic; mitochondria, lysosomes, and lipid droplets act as integrated rheostats for cell death execution.\n*   **Transcriptional Regulation of Lipid Metabolism:** Histone acylation (H3K18la) directly modulates ACSL4 to trigger ferroptosis in myocardial ischemia-reperfusion scenarios.\n*   **Viral Manipulation:** EBV latency III programs are found to redirect methionine metabolism toward redox defense, specifically inducing transsulfuration to sustain cysteine and glutathione pools, creating a targetable ferroptotic vulnerability.\n*   **Radiation Synergy:** Ferroptosis induction is a key driver of the synergistic efficacy observed in combined radiotherapy and KRAS inhibition in pancreatic cancer models.\n*   **Immune/Ferroptosis Crosstalk:** Ferroptosis-related transcriptional activities are dynamically activated alongside pyroptosis and necroptosis after spinal cord injury, suggesting a collaborative lytic cell death program.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In this study, we identify Arachidonate 12-lipoxygenase (ALOX12) as a previously unrecognized ferroptosis-related tumor suppressive regulator with significant diagnostic and prognostic value in OC. By integrating Weighted Gene Co-expression Network Analysis (WGCNA), machine learning algorithms, and survival modeling, and validating our findings through in vitro and in vivo experiments, transcriptomic profiling, and biochemical assays, we systematically characterized the biological and mechanistic roles of ALOX12. Our analysis revealed that ALOX12 is markedly downregulated in OC tissues, with its low expression correlating with poor clinical outcomes. Functional experiments further demonstrated that ALOX12 suppresses OC cell proliferation, invasion, and migration, while promoting apoptosis and ferroptosis-associated lipid peroxidation. Mechanistically, transcriptome sequencing and protein assays pinpointed MAPK signaling as a key pathway modulated by ALOX12. Additionally, our experiments revealed that ALOX12 exerts its effects by regulating HSPA6 expression. Collectively, these findings highlight ALOX12 as a promising biomarker and potential therapeutic target, offering new insights into ferroptosis-associated signaling networks and their implications for improving the management of OC.\n\nID: 42526057\nTitle: Dysregulated Iron Metabolism In Remodeling of Aging Asthmatic Human Airways.\nAbstract: Iron is essential for cellular function, and lung cells are no exception. Previous studies have demonstrated an association between increased level of iron in the lung and aging and age-related lung diseases including pulmonary fibrosis and asthma in the elderly (AIE). However, the mechanisms underlying the accumulation of iron with aging or AIE, or the cell types involved, remain understudied. In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling.\n\nID: 42526049\nTitle: Subcellular Regulation of Ferroptosis: Roles of Individual Intracellular Organelles and Crosstalk.\nAbstract: Ferroptosis is an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation. Emerging evidence indicates that susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets. Mitochondria play dual roles in ferroptosis by integrating metabolic activity, redox balance, and mitochondrial quality control; thereby influencing reactive oxygen species generation and lipid peroxidation. Lysosomes regulate ferroptotic sensitivity through iron mobilization, inter-organelle iron transfer, lysosomal redox activity/lipid peroxidation, lysosomal signaling hub, and ferritinophagy. The ER contributes to ferroptosis by coordinating lipid biosynthesis, membrane polyunsaturated fatty acid composition, and unfolded protein response signaling, as well as by disrupting antioxidant defenses and iron homeostasis, especially during ER stress. Lipid droplets function as dynamic lipid reservoirs that buffer oxidizable fatty acids or, upon mobilization, supply substrates that fuel ferroptosis-associated lipid peroxidation. Here, we provide a comprehensive review of current mechanistic insights and recent advances in organelle-specific regulation and inter-organelle crosstalk during ferroptosis, highlighting emerging therapeutic opportunities and key experimental challenges. An integrated understanding of this multi-organelle regulatory network is essential for modulating ferroptosis in human diseases.\n\nID: 42525293\nTitle: Targeting autophagy in oral squamous cell carcinoma chemoresistance: molecular mechanisms, therapeutic strategies, and emerging nanotherapeutic approaches.\nAbstract: Autophagy is a lysosome-dependent recycling process that maintains cellular homeostasis and helps cells adapt to therapeutic stress. In oral squamous cell carcinoma (OSCC), dysregulated autophagy may promote chemoresistance by supporting metabolic adaptation, removing damaged cellular components, and limiting treatment-induced cell death. Its effects are nevertheless context dependent, as autophagy can also interact with apoptosis, ferroptosis, and other cytotoxic pathways. This review summarizes molecular mechanisms linking autophagy to OSCC chemoresistance, focusing on non-coding RNAs, p53/TP53, BECN1, ATG-related proteins, oncogenic signaling networks, and emerging biomolecular-condensate mechanisms. It also evaluates therapeutic strategies, including early- and late-stage autophagy inhibition, mTOR-targeted modulation, metabolic interventions, genetic approaches for mechanistic validation, ferroptosis-autophagy combinations, and nanotechnology-assisted delivery systems. Although promising effects have been reported in cell lines, drug-resistant derivatives, cancer stem cell-like populations, and xenograft models, OSCC-specific clinical evidence remains limited. Future progress will require rigorous assessment of autophagic flux, careful interpretation of related head and neck squamous cell carcinoma evidence, biomarker-guided patient stratification, and validation in clinically relevant models. Integrating autophagy biology with molecular stratification and rational combination therapy may help overcome chemoresistance in OSCC.\n\nID: 42525168\nTitle: Celastrol attenuates synovial inflammation and experimental arthritis by modulating PTGS2-associated ferroptosis resistance in fibroblast-like synoviocytes.\nAbstract: Rheumatoid arthritis (RA) is characterized by persistent synovial inflammation and aggressive activation of fibroblast-like synoviocytes (FLS). Celastrol has recognized anti-inflammatory activity, but its mechanism in RA remains incompletely defined. This study investigated whether the anti-arthritic effect of celastrol is associated, at least in part, with a PTGS2-associated ferroptosis-resistance pathway in FLS. Potential targets of celastrol in RA were identified through integrated bioinformatic analyses. Collagen-induced arthritis (CIA) rats and primary FLS were used to evaluate the effects of celastrol in vivo and in vitro. Joint pathology, inflammatory mediator expression, oxidative stress, iron accumulation, lipid peroxidation, and ferroptosis-related proteins were assessed. Loss- and gain-of-function experiments were performed to examine the functional role of PTGS2. Bioinformatic screening identified PTGS2 as a candidate functional mediator linking celastrol to RA. In CIA rats, celastrol reduced paw swelling, arthritis severity, synovial hyperplasia, inflammatory cell infiltration, and cartilage and bone destruction. In FLS, celastrol suppressed cell proliferation and migration and decreased the expression of pro-inflammatory cytokines. Mechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment. PTGS2 expression was markedly elevated in RA models and was downregulated by celastrol. PTGS2 overexpression attenuated the anti-inflammatory effects of celastrol and reversed several ferroptosis-associated changes, supporting a functional role for PTGS2 in this process. Celastrol alleviates synovial inflammation and experimental arthritis, at least in part, in association with PTGS2 modulation and attenuation of a ferroptosis-resistant phenotype in FLS. To our knowledge, these findings provide experimental evidence linking celastrol, PTGS2-associated regulation, and ferroptosis resistance in RA models.\n\nID: 42524611\nTitle: Exploring Lipid Metabolic Reprogramming: Mechanistic Insights and Implications for Tumor Radiotherapy.\nAbstract: Lipid metabolic reprogramming plays a crucial role in modulating tumor responses to radiotherapy by influencing radiation-induced oxidative damage, membrane repair, ferroptosis, energy stress, and immune regulation. Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis, cholesterol and phospholipid remodeling that impacts membrane integrity and lipid rafts, lipid droplet-mediated buffering of metabolic stress, fatty acid oxidation-dependent energy supply, and sphingolipid-regulated apoptosis. This review delineates pre-existing tumor lipid programs from IR-induced adaptive responses, highlighting that their contributions to radiosensitivity or radioresistance are contingent upon tumor lineage, genetic background, microenvironmental conditions, and treatment context. The coupling of cancer cells with their microenvironment through lipid interactions, encompassing intercellular lipid transfer, nutrient competition, paracrine lipid mediators, and exosome-mediated signaling, is identified as a central component of radioresistance. In conclusion, therapeutic opportunities are evaluated based on their translational maturity, encompassing a spectrum from mechanistic concepts and preclinical radiosensitization strategies to approaches with emerging clinical significance. This synthesis, focused on radiotherapy, seeks to elucidate how lipid vulnerabilities can be strategically and judiciously exploited to enhance radiation outcomes.\n\nID: 42524518\nTitle: ZDHHC-Mediated Protein S-Palmitoylation in Cancer: Epigenetic Interfaces, Structural Logic and Therapeutic Targeting.\nAbstract: Protein S-palmitoylation, the reversible thioesterification of cysteine side chains, is emerging as a druggable post-translational modification that couples membrane topology to oncogenic, metabolic, immune, and epigenetic networks in cancer. ZDHHC palmitoyltransferases and depalmitoylating enzymes, including acyl-protein thioesterases and palmitoyl-protein thioesterase 1, constitute a dynamic circuitry that governs the localization, stability, and signaling competence of key regulators of tumor growth, metabolic adaptation, and immune phenotype. Here, we synthesize recent structural and chemical biology advances that clarify how human ZDHHC enzymes achieve acyl-chain recognition and substrate engagement. Structural studies show that these enzymes adopt a four-transmembrane, \"tent-like\" fold, in which the helices create a membrane-embedded cavity for acyl-chain accommodation. We also discuss how ankyrin-repeat domains and accessory partners shape substrate recruitment and subcellular localization, and we highlight emerging high-throughput platforms that enable quantitative profiling of isoform- and site-selective modulators. We then discuss how ZDHHC-substrate circuits rewire canonical growth-factor signaling and epithelial-mesenchymal transition programs, metabolic and ferroptotic control nodes, innate immune sensing, and chromatin-linked regulation. These convergent mechanisms position ZDHHC-mediated S-palmitoylation as a context-dependent regulator of tumor progression, therapy response, ferroptosis sensitivity, and immune phenotype. Finally, we outline a translational framework encompassing clinical-stage PPT1 inhibitors, selective ABHD17 blockade, emerging ZDHHC modulators, substrate-competitive strategies targeting checkpoint palmitoylation, and selected comparator approaches affecting Wnt and Hedgehog ligand lipidation. Current evidence positions ZDHHC-mediated S-palmitoylation as a regulatory layer with potential biomarker and therapeutic relevance; however, not all reported ZDHHC-substrate associations carry equivalent evidentiary weight. Mechanisms supported by convergent site-directed, genetic, biochemical, functional, and in vivo evidence should be distinguished from associations inferred mainly from expression profiling, overexpression systems, single-model observations, or broad pharmacological perturbation. Clinical translation remains preliminary and is constrained by isoform selectivity, substrate redundancy, incomplete pharmacodynamic read-outs, and the absence of validated biomarker-guided patient stratification.\n\nID: 42524498\nTitle: SYNCRIP drives ferroptosis resistance and metabolic activation via SIRT1 and HK2 in glioblastoma.\nAbstract: Synaptotagmin-binding cytoplasmic RNA-interacting protein (SYNCRIP) is an RNA-binding protein (RBP) implicated in the pathogenesis of various cancers through involvement in regulating multiple cellular processes. Notably, this study identified that SYNCRIP expression is significantly elevated in glioblastoma (GBM) and is associated with poor prognosis and tumor progression. Mechanistically, SYNCRIP upregulates SIRT1 expression at both the transcriptional and post-transcriptional levels by stabilizing SIRT1 mRNA. Meanwhile, loss of SYNCRIP leads to reduced SIRT1 expression, accumulation of reactive oxygen species (ROS), and induction of ferroptosis. Notably, restoration of SIRT1 rescues cells from ferroptotic cell death, supporting the critical role of SIRT1 in SYNCRIP-mediated ferroptosis resistance. SYNCRIP also enhances hexokinase 2 (HK2) expression through transcriptional activation and internal ribosome entry site (IRES)-mediated translation, thereby promoting glycolytic activity in GBM. Furthermore, depletion of SYNCRIP results in mitochondrial dysfunction and impairs GBM cell migration and invasion by downregulating epithelial-mesenchymal transition (EMT)-associated factors. Collectively, these findings suggest that SYNCRIP is a key regulator of GBM progression by maintaining metabolic homeostasis and ferroptosis resistance, highlighting SYNCRIP as a potential therapeutic target in GBM.\n\nID: 42524322\nTitle: Long Non-Coding RNA PVT1 Promotes Doxorubicin Resistance by Inhibiting Ferroptosis in Breast Cancer.\nAbstract: There is growing evidence that long non-coding RNAs (lncRNAs) play crucial roles in cancer progression and therapy. Our previous study showed that the lncRNA plasmacytoma variant translocation 1 (PVT1) regulates tumor growth and metastasis in breast cancer (BC). As a conventional chemotherapeutic drug, doxorubicin (DOX) resistance continues to be a major challenge in BC treatment. This study aimed to explore the role and underlying mechanism of PVT1 in doxorubicin-resistant BC. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blotting (WB) were carried out to detect gene and protein expression levels. The extent of ferroptosis was measured based on the cellular glutathione (GSH) levels and total or lipid reactive oxygen species (ROS) levels. An in-situ tumor implantation model in nude mice was employed to validate the mechanism in vivo. Transcriptome analysis was conducted to identify downstream target genes. This study found that PVT1 was highly expressed in the plasma of drug-resistant patients and drug-resistant cell lines. Silencing PVT1 reduced cellular glutathione level, increased reactive oxygen species (ROS) and lipid peroxidation (LPO), while ferroptosis inhibition in rescue experiments partially reversed the oxidative stress. In-vivo study confirmed that silencing PVT1 increased the sensitivity of BC cells to doxorubicin treatment. Transcriptomic sequencing revealed that solute carrier family 3 member 2 (SLC3A2) was the most potential target gene of PVT1, which was confirmed in PVT1-silenced cell models. Mechanistically, PVT1 increased SLC3A2 expression, thus inhibiting ferroptosis and promoting doxorubicin resistance in BC, indicating that PVT1 could be a promising therapeutic target for doxorubicin-resistant BC patients.\n\nID: 42524207\nTitle: Arteannuin B Induces Ferroptosis in Colorectal Cancer Cells via GDF15/HMGCS1/GPX4 Axis.\nAbstract: Drug resistance in colorectal cancer (CRC) necessitates novel therapeutic strategies. This study investigated whether arteannuin B, a sesquiterpene lactone from Artemisia annua, induces ferroptosis in CRC cells and elucidated the underlying molecular mechanism. Anti-CRC effects were assessed via MTT assays and xenograft models. Proteomics identified differentially expressed proteins. Arteannuin B-induced ferroptosis was confirmed by measuring reactive oxygen species (ROS), lipid peroxidation, Fe\u00b2\u207a content, glutathione peroxidase 4 (GPX4) expression, and mitochondrial morphology. Mevalonate pathway regulation was evaluated by western blotting, dual-luciferase assay, and quantification of squalene, coenzyme Q10 (CoQ10), and cholesterol. The role of growth differentiation factor 15 (GDF15) was validated using shRNA knockdown and overexpression DLD-1 cells in vitro and in vivo. Arteannuin B showed significant anti-colorectal cancer activity both in vitro and in vivo. The proteomic analysis demonstrated that arteannuin B affected the mevalonate pathway and ferroptosis in DLD-1 cells, and strongly upregulated the expression of GDF15. Arteannuin B increased ROS, lipid peroxidation, malondialdehyde, and iron while decreasing GPX4 expression and causing mitochondrial shrinkage. Arteannuin B inhibited mevalonate pathway enzymes, particularly 3-hydroxy-3-methylglutaryl-CoA synthase 1 (HMGCS1), reducing squalene, CoQ10, and cholesterol. The knockdown of GDF15 weakened the inhibitory effect of arteannuin B on the mevalonate pathway and GPX4, and reduced the sensitivity of CRC cells to arteannuin B both in vitro and in vivo. Arteannuin B triggers ferroptosis-like cell death in CRC cells and suppresses xenograft growth, in association with inhibition of the mevalonate pathway. GDF15 contributes to arteannuin B-mediated suppression of HMGCS1 and GPX4 and to ferroptosis sensitivity.\n\nID: 42524197\nTitle: A Prognostic Risk Model for Hepatocellular Carcinoma Integrating Ferroptosis and Metabolic Reprogramming Signatures.\nAbstract: Hepatocellular carcinoma (HCC) continues to impose a heavy global health burden, with high incidence and mortality. The disease is highly heterogeneous and is commonly detected at late stages, which compromises treatment outcomes. Ferroptosis and metabolic reprogramming are increasingly recognized as key processes in HCC development; however, their roles in disease progression and therapeutic response remain incompletely understood. This research aimed to identify genes related to ferroptosis and metabolic reprogramming (FPMRRGs) that may serve as putative biomarkers and therapeutic targets in HCC. The Cancer Genome Atlas (TCGA), including 369 HCC specimens and 50 normal controls, along with two Gene Expression Omnibus (GEO) datasets (GSE10143 and GSE76427), were analyzed using R (v4.3.3). From a curated list of 451 FPMRRGs, differentially expressed genes (DEGs) between tumor and normal tissues were identified. Univariate Cox regression analysis was then conducted to explore their prognostic relevance and to define molecular subtypes of HCC. Specimens were categorized into 2 subtypes using ConsensusClusterPlus, and overall survival differences were evaluated via survival analysis. Functional and pathway enrichment analyses were conducted to investigate the functional roles of these genes. Immune-related features were evaluated using the Mann-Whitney U test. A prognostic risk model was constructed using least absolute shrinkage and selection operator (LASSO) regression followed by multivariate Cox analysis. Model performance was assessed using receiver operating characteristic (ROC) curves and calibration plots. Immune cell infiltration was estimated by single-sample GSEA, and pathway activity differences were examined using gene set variation analysis (GSVA). HCC specimens were divided into 2 molecular subtypes, which demonstrated obvious differences in overall survival and immune-related features, including immune checkpoint gene expression and tumor immune dysfunction and exclusion (TIDE) scores. A prognostic model based on 12 key FPMRRGs demonstrated good predictive performance for 1- and 3-year overall survival, with moderate performance for 5-year survival. The prognostic value and expression patterns of these genes were further validated across independent datasets. In addition, these genes were mainly enriched in pathways linked to fatty acid metabolism and HIF-1 signaling, and were closely associated with patterns of immune cell infiltration. This study identified numerous key genes linked to ferroptosis and metabolic reprogramming in HCC and developed a robust prognostic risk model. Our results offer new insight into the molecular basis of HCC and highlight potential biomarkers for more individualized treatment approaches. Further studies, particularly those combining clinical validation with functional experiments, are required to verify these findings and examine the therapeutic potential of targeting these pathways.\n\nID: 42524084\nTitle: Ferroptosis regulatory networks as therapeutic sensitizers in combination therapy for hepatocellular carcinoma (Review).\nAbstract: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, and multidrug resistance remains a major barrier to effective treatment. Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. The present narrative review summarizes current evidence on ferroptosis-mediated sensitization mechanisms in combination therapy for HCC, focusing on core regulatory networks, including glutathione peroxidase 4, System Xc- and iron metabolism pathways, and their interactions with key signaling pathways, such as activating transcription factor 4/signal transducer and activator of transcription 3, p53 and Wnt/\u03b2-catenin. The current review also discusses the synergistic effects and molecular mechanisms of ferroptosis inducers combined with targeted therapy, chemotherapy and immunotherapy. Furthermore, the potential value of ferroptosis-related biomarkers for predicting treatment response and prognosis is evaluated, and unresolved mechanistic questions and barriers to clinical translation are highlighted. Finally, the present review outlines future research directions, including the development of targeted nanodelivery systems and biomarker-based clinical trials, to support more precise ferroptosis-based combination strategies for HCC.\n\nID: 42524008\nTitle: Ferroptosis contributes to quercetin-induced anti-cancer activity through blockade of LGR4/NF-\u03baB/GPX4 axis in oral squamous cell carcinoma.\nAbstract: Oral squamous cell carcinoma (OSCC) is a malignancy that faces challenges such as chemotherapy resistance and side effects. There is an urgent need for effective, low-toxicity compounds to treat OSCC. Here, we examined whether quercetin induces ferroptosis in OSCC cells and explored the potential molecular mechanisms. The role of LGR4/NF-\u03baB/GPX4 in OSCC cells (CAL27 and SCC9) was studied through gene overexpression or RNA interference. Additionally, OSCC cell lines were treated with quercetin to examine its effects and underlying mechanisms in OSCC. Quercetin dose-dependently reduced the viability of OSCC cells, while co-treatment with the ferroptosis inhibitor liproxstatin-1 significantly counteracted quercetin-induced cell death. RNA-seq analysis showed that quercetin's inhibitory effect on OSCC cells is linked to ferroptosis induction. Quercetin concentration-dependently decreased GPX4 expression in OSCC cells by suppressing the LGR4/NF-\u03baB signaling pathway. LGR4-induced ferroptosis inhibition was counteracted by either quercetin or an NF-\u03baB inhibitor. Mechanistically, LGR4 could induce upregulation of IKK\u03b2, leading to I\u03baB\u03b1 ubiquitination and degradation, which promotes NF-\u03baB activation and GPX4 transcription, ultimately inhibiting ferroptosis in OSCC cells. Our findings indicate that ferroptosis may play a role in quercetin's anti-OSCC activity by blocking the LGR4/NF-\u03baB/GPX4 axis, which supports the potential use of quercetin as a therapeutic agent for OSCC.\n\nID: 42523794\nTitle: Programmed cell death mechanisms of traditional plant medicine in prostate cancer therapy.\nAbstract: Prostate cancer (PCa) is a prevalent malignancy in males with high morbidity and mortality. Although treatment modalities have evolved considerably, tumor resistance, recurrence, and metastasis persist, urgently requiring the exploration of alternative therapies for PCa. There is ongoing research on finding and identifying the use of traditional plant medicine (TPM). Cellular homeostasis comprises a sophisticated network of metabolic processes that functions cooperatively to preserve a stable intracellular environment. Programmed cell death (PCD) plays an important role in PCa mechanism. Thus, they represent an effective strategy for targeting PCa. TPM has been proven to induce PCD through multiple pathways and target in the treatment of PCa. Recent reviews have only focused on the one of the PCD, and autophagy, apoptosis, pyroptosis, ferroptosis, and necroptosis are not simultaneously reviewed. The search strategy: articles with the title containing \"prostate cancer\", \"therapeutic\", \"traditional medicine\", \"apoptosis\", \"pyroptosis\", autophagy\", \"in vivo/in vitro\", \"active ingredients\", \"Herbal\", \"real modules\", \"dose\", \"pathway\", \"effects/mechanisms\", \"extract\", \"pure compound\", \"drug type\", \"anticancer activity\", \"Chinese herbal compounds\", \"necroptosis\" and \"ferroptosis\" had been initially selected in the past five years databases of PubMed, Web of Science, and ScienceDirect. The references were screened according to the strategy. Forty-two drugs in the TPM have been chosen in this review. The plant extract, Chinese herbal compound, and pure compound of TPM exhibit significant anticancer activity against PCa by regulating multiple kinds of PCD. More importantly, PI3K/AKT/mTOR, AMPK/mTOR pathways, AKT1/Bcl2/NF-\u03baB, GPBAR1/NF-\u03baB, Keap1/Nrf2/ARE, PINK1/Parkin signaling pathways serve as critical molecular targets mediating the anticancer activities of TPMs in PCD. Autophagy, apoptosis, and ferroptosis are research hotspots, while pyroptosis and necroptosis are less explored. Apoptosis is co-detected with autophagy, or necroptosis. Ferroptosis is co-detected with necroptosis, or pyroptosis. Notably, the interrelationships between these cell death modes are rarely investigated in depth in the treatment of TPM in PCa. TPM has been induced apoptosis, ferroptosis, necroptosis in PCa. But the effect of TPM on the autophagy and pyroptosis need further evidence to clarify the mechanism. Hence, it is imperative to focus on elucidating the role of PCD modulators to refine therapeutic strategies of TPM in PCa.\n\nID: 42523681\nTitle: Hysterectomy accelerates sarcopenia risk in US women and mouse models.\nAbstract: Sarcopenia represents a clinical condition with particular prevalence among postmenopausal women. Hysterectomy is a common gynecological surgical procedure associated with various complications. However, the relationship between hysterectomy and sarcopenia remains poorly investigated. This study aimed to explore the association between hysterectomy and sarcopenia risk. Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES, 2001-2018) was utilized for analysis. Sarcopenia was defined using the Foundation for the National Institutes of Health (FNIH) criteria based on ALM/BMI < 0.512 in women. Multivariable logistic regression and propensity score matching were applied to assess the association between hysterectomy and sarcopenia. In parallel, a senescence-accelerated mouse model (SAMP8) was used to examine the effects of hysterectomy on muscle function and related molecular pathways, including markers of protein degradation and ferroptosis. In the NHANES cohort, hysterectomy was associated with an increased risk of sarcopenia after adjustment for covariates (OR\u00a0=\u00a01.35; 95% CI: 1.00-1.82; p\u00a0=\u00a00.049). The association was stronger in women who had undergone both hysterectomy and oophorectomy (OR\u00a0=\u00a02.06; 95% CI: 1.45-2.93; p\u00a0<\u00a00.001). In SAMP8 mice, hysterectomy was associated with reduced grip strength, shorter endurance time, and decreased muscle fiber size. Molecular analyses suggested activation of the FOXO1-MuRF-1/Atrogin-1 pathway and changes consistent with ferroptosis-related signaling. Hysterectomy appears to be associated with an increased risk of sarcopenia in women, and this association is supported by findings from an experimental mouse model. These results suggest potential involvement of muscle protein degradation and ferroptosis-related pathways, although further studies are needed to clarify causality.\n\nID: 42523460\nTitle: Adenine nucleotide translocase 2 (ANT2) deficiency reprograms ferroptosis in alveolar progenitor cells to promote emphysema.\nAbstract: Stem cell dysfunction and loss of renewal capacity are primary characteristics of tissue aging and decremental regeneration in response to injury. Alveolar type 2 cells (AT2) are key progenitor cells responsible for lung repair and are thought to be dysfunctional in diseases such as chronic obstructive pulmonary disease (COPD). AT2 cells are highly metabolic and rely on mitochondria, but how mitochondrial mechanisms influence their maintenance and cell fate is unclear. This gap is critical as no current therapies target lung repair or mitochondrial function in COPD. Here, we report that adenine nucleotide translocase 2 (ANT2), a key ATP/ADP transporter, is reduced in AT2 cells from COPD lungs, and that ANT2 loss impairs bioenergetics (ATP). We also identify, for the first time, ferroptotic susceptibility as a consequence of ANT2 loss in AT2 cells, leading to impaired self-renewal and progenitor capacity in alveolar organoids. Together, loss of ANT2 and the associated cellular dysfunction resulted in worsened lung damage or emphysema due to cigarette smoke in mice. Therapeutic restoration of ANT2 expression resulted in renewed AT2 stem cell function and prevention of emphysema by reducing oxidative stress and ferroptosis. These findings highlight the importance of ANT2 in metabolic regulation, plasticity, and cell resiliency of AT2 cells in the lung and that ANT2 is a potential target for lung repair.\n\nID: 42523398\nTitle: Concurrent Stereotactic Body Radiation Therapy and KRAS Inhibition Synergistically Improve Pre-clinical Pancreatic Cancer Treatment.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) is one of the most challenging cancers to treat due to the dismal survival rate, poor post-treatment outcome and profound resistance to a wide range of therapies. With mutant KRAS being a key driver, small molecule inhibitors targeting KRAS or pan-RAS (KRASi) have demonstrated exciting preclinical and early clinical anti-tumor efficacy, and the pan-RAS(ON) inhibitor daraxonrasib (RMC-6236) recently achieved Phase 3 clinically meaningful improvements in patient survival compared to chemotherapy. But resistance to RAS/KRAS inhibitor inevitably develops, which limits and compromises the treatment outcome. In this study, we investigated the combination of stereotactic body radiation therapy (SBRT) and KRAS inhibition (MRTX1133 and daraxonrasib) in the treatment of preclinical PDAC models. We found that this combination strategy synergistically suppresses PDAC cell growth in vitro and enhances tumor control while minimizing local recurrence in orthotopically implanted KPC ( LSL-Kras G12D/+ ;Trp53 R172H/+ ;Pdx1-Cre ) murine PDAC tumors in vivo . As radiation therapy (RT) induces ferroptosis in multiple cancer types and mutant KRAS promotes various anti-ferroptotic mechanisms, we tested the role of ferroptosis in promoting tumor-control efficacy. Intriguingly, the addition of a ferroptosis inhibitor, liproxstatin-1, to the combination therapy significantly abrogated the in vivo synergism between SBRT and KRAS inhibition, suggesting that treatment-induced ferroptosis at least partially drives the synergistic efficacy of this combination strategy. Our study indicates that this SBRT-KRASi combination has the potential to overcome treatment resistance and improve outcomes in PDAC patients. These data directly support the design of a planned multi-center Phase 2 clinical trial with this combination strategy in locally advanced PDAC.\n\nID: 42523372\nTitle: TIAR-dependent coordination of alternative splicing and lipid peroxidation is required for CML cell resistance to imatinib in the bone marrow stroma.\nAbstract: Chronic myeloid leukemia (CML) is treated with Abl1 tyrosine kinase inhibitors (TKIs). Quiescent cancer cells residing in the bone marrow (BM) can survive the treatment and cause CML relapse. We previously found that a subset of alternative splicing (AS) changes detected in CML cells surviving months of therapy are initiated within hours of treatment onset. Here, we investigated how AS in CML cells is modulated by the human BM microenvironment. By incorporating humanized BM niche models in vivo, we uncovered stroma-induced transcriptome adaptation that influences transcriptional regulation, transmembrane transport, lipid metabolism, the tricarboxylic acid cycle, and respiratory electron transport. We identified RNA-binding protein TIAR (T-cell intracellular antigen-related protein) as a key mediator of CML survival under TKI imatinib treatment. Our data show TIAR-dependent coordination of RNA processing with the metabolic program induced by stromal interaction. Quantitative nascent proteome analysis revealed that TIAR silencing affects the synthesis of metabolic enzymes and proteins involved in imatinib-induced erythroid differentiation. Besides, TIAR knockdown increased lipid peroxidation in untreated cells and decreased reduction potential in cells upon imatinib treatment. Taken together, TIAR deficiency reduces CML survival, possibly by inducing ferroptosis. These findings identify TIAR-dependent RNA processing within the BM niche as a previously unrecognized mechanism of CML therapy resistance and a potential therapeutic vulnerability.\n\nID: 42523303\nTitle: An IL-34-IGF-1 inflammatory axis fuels KRAS-mutant lung cancer progression.\nAbstract: Macrophages are innate immune cells of embryonic or adult origin with tissue specific roles in homeostasis, disease surveillance, and wound repair that can be co-opted to promote tumor growth and spread 1-11 . An understanding of the specific roles of macrophage subsets in lung tumor initiation and progression could promote new therapeutic approaches for this deadly disease. Here, we show that KRAS G12D mutations in lung epithelium drive proliferation of resident, embryonically-derived alveolar macrophages, which then promote tumor cell proliferation and protection from ferroptosis, leading to tumor progression. Using genetically engineered mouse models of mutant KRAS G12D non-small cell lung cancer 12,13 , we found that alveolar macrophages accumulate by proliferation in response to tumor cell-secreted IL-34, recapitulating events observed in late embryonic lung development. Tumor alveolar macrophages in turn drive IGF-1-dependent tumor cell proliferation. Neutralization or deletion of IL-34 suppresses IGF-1 expression, reduces macrophage and tumor cell proliferation and inhibits tumor progression. High IL34 and IGF1 correlate with poor survival in KRAS G12D/V lung adenocarcinomas and in other solid tumors, indicating that bi-directional proliferative signaling between resident macrophages and tumor cells can drive human lung tumor progression. These studies identify resident macrophage-tumor cell interactions as key interception points for lung cancer therapy.\n\nID: 42523280\nTitle: Epstein-Barr virus transformation creates a methionine-dependent ferroptosis vulnerability in B cells.\nAbstract: Epstein-Barr virus (EBV) causes over 200,000 cancers annually, including immunoblastic lymphomas in immunosuppressed hosts. Most transformed cells arrest, yet survive when deprived of the essential amino acid methionine. We instead find that EBV transformed lymphoblastoid cell lines (LCLs), which model the EBV latency III program-driven B-cell lymphoproliferative diseases of immunosuppressed hosts, rapidly die upon methionine restriction. Methionine restriction elevated LCL lipid reactive oxygen species and triggered ferroptosis. Whereas methionine restriction hypomethylates the EBV genome and triggers viral reactivation in latency I Burkitt cells by lowering the cellular methylation potential, the LCL latency III program instead redirected methionine toward redox defense, without altering the SAM/SAH ratio. Stable-isotope tracing revealed that latency III strongly induces transsulfuration, synthesizing cysteine de novo to support glutathione pools. The EBV oncoprotein LMP2A, which mimics B-cell receptor signaling, supported newly infected human B cell cystathionine-\u03b2-synthase and cystathionine-\u03b3-lyase expression and methionine dependence, phenocopied by immunoglobulin crosslinking. In vivo , dietary methionine restriction impaired LCL xenograft outgrowth and depleted tumor cystine. Combined methioninase and cyst(e)inase administration blocked both cysteine sources, collapsed tumor glutathione levels, and triggered ferroptosis. Our results define methionine metabolism as a targetable ferroptosis vulnerability of EBV-transformed B cells. Methionine restriction triggers EBV-transformed lymphoblastoid B cell ferroptosisEBV latency III induces transsulfuration to sustain LCL cysteine and glutathione Methioninase or dietary methionine restriction strongly impair LCL growth in vivo Methioninase plus cyst(e)inase collapses xenograft GSH levels and drives ferroptosis.\n\nID: 42523149\nTitle: Novel blood lncRNA biomarkers associated with clinical severity and specific cognitive dimensions in Alzheimer's disease.\nAbstract: BackgroundDifferential expression of long non-coding RNAs (lncRNAs) in brain, serum, and blood show strong potential to distinguish Alzheimer's disease (AD) from healthy controls.ObjectiveTo explore whether lncRNA signatures delineate AD pathology and map to distinct, multidimensional cognitive domains, enhancing specificity in assessing AD severity and progression.MethodsWe profiled 29,603 lncRNAs transcripts in blood samples from 15 AD patients and 15 healthy controls, alongside comprehensive neuropsychological assessments. Generalized Linear Models and Predictive Power Score analyses, with statistical prioritization, identified lncRNAs associated to AD neuropsychological architecture.ResultsSeveral lncRNAs share strongly associated with cognitive performance and AD severity, mapping to genes involved in key AD-related molecular processes, including synaptic and neurotransmitter regulation (e.g., EPHB1, CHRNA4, TEAD1), protein homeostasis and A\u03b2 pathology (e.g., FBXL2, FAM221A, APP), mitochondrial function and cellular stress (e.g., VDAC3, PPT2-EGFL8), neuroinflammation and immune regulation (e.g., TEAD1, EMX2OS, LY6E-DT), epigenetic and transcriptional control (e.g., PRDM2, DLEU1, FIRRE), neuronal excitability (e.g., KCNJ14), and neuroprotection and synaptic plasticity (e.g., SIL1). Novel associations included ferroptosis, DNA stability, microtubule dynamics, and dendritic orientation (e.g., BTB3, DICER1, GNG7, IBA57, NEAT1, POT1, SRD5A3).ConclusionsWe identify candidate lncRNA signatures that may serve as potential biomarkers and enhance our understanding of the molecular basis of the cognitive architecture in AD, opening new avenues for biomarker identification and targeted therapeutic strategies development. Validation in larger, diverse cohorts is essential to confirm their mechanistic contributions to AD.\n\nID: 42522960\nTitle: Lactate/AARS1-mediated H3K18la in the modulation of ACSL4 transcription to trigger ferroptosis in myocardial ischemia reperfusion.\nAbstract: Hypertension serves as a pivotal risk factor for myocardial ischemia reperfusion injury (MIRI). Reciprocally, MIRI exacerbates hypertension by inducing oxidative stress, inflammatory responses, cardiomyocyte death, fibrosis-associated myocardial remodeling, and RAAS system disruption, forming a vicious feedback cycle. This study aimed to investigate the regulatory role and underlying molecular mechanism of the lactate-related signaling axis in cardiomyocyte ferroptosis during MIRI, and to identify novel potential therapeutic targets for interrupting this detrimental feedback loop. In vivo mouse MIRI models, in vitro cardiomyocyte oxygen\u2012glucose deprivation/reoxygenation (OGD/R) models, and spontaneously hypertensive rat (SHR) models were successfully established. Oxaloacetate and \u03b2-alanine were administered to inhibit lactate production and protein lactylation, respectively. Hematoxylin\u2012eosin (HE) and Masson staining were performed to evaluate myocardial histopathological damage and fibrosis. Immunohistochemistry (IHC) and Western blotting were used to detect the protein expression levels of lysine lactylation (Kla), H3K18la, alanyl-tRNA synthetase 1 (AARS1), and acyl-CoA synthetase long-chain family member 4 (ACSL4). An enzyme-linked immunosorbent assay (ELISA) was adopted to quantify the lactate content and ferroptosis-related marker levels. Transmission electron microscopy (TEM), immunofluorescence staining, and chromatin immunoprecipitation (ChIP) assays were separately utilized to observe the mitochondrial ultrastructure, assess cellular lipid peroxidation, and verify gene promoter enrichment. Lactate, Kla, and H3K18la levels were markedly elevated in the MIRI and OGD/R models, accompanied by severe myocardial injury, fibrosis, and excessive cardiomyocyte ferroptosis. Inhibition of lactate production effectively reduced lactylation levels and mitigated ferroptosis as well as myocardial structural damage. Mechanistically, H3K18la was enriched in the promoter region of ACSL4 to facilitate its transcriptional activation, and knockdown of ACSL4 markedly reversed OGD/R-triggered cardiomyocyte ferroptosis. AARS1 overexpression strengthened lactylation and ACSL4 expression to promote ferroptosis, while its mutant did not. Notably, hypertension aggravated MIRI, promotes further increases in the level of histone lactylation mediated by AARS1, and exacerbates ferroptosis. Pharmacological intervention with \u03b2-alanine blocked the lactate/AARS1/H3K18la/ACSL4 axis and attenuated MIRI-induced myocardial damage. Abnormal lactate accumulation facilitates H3K18la modification via AARS1-dependent regulation, which transcriptionally activates ACSL4 and modulates cardiomyocyte ferroptosis, ultimately contributing to the pathological progression of MIRI. Targeting the lactate/AARS1/H3K18la/ACSL4 regulatory axis is a promising and viable therapeutic strategy for MIRI intervention.\n\nID: 42522408\nTitle: Comment on \"Ferroptosis-Related Signature Genes and Immune Landscape in Acute Exacerbation of Chronic Obstructive Pulmonary Disease\".\nAbstract: \n\nID: 42522134\nTitle: A Therapeutic Copper Hydrogel for Seborrheic Dermatitis: From Fungal Eradication to Skin Lesion Repair.\nAbstract: Seborrheic dermatitis (SD) is a chronic relapsing inflammatory dermatosis closely associated with Malassezia furfur overgrowth. Given the growing interest in metal-based antimicrobials, copper compounds were investigated here as potential anti-Malassezia agents for SD treatment. CuSO4 showed the strongest antifungal activity against M. furfur at 1\u00a0mM and rapidly reduced fungal viability. Mechanistic analyses revealed intracellular copper accumulation, elevated Fe2+ levels, increased reactive oxygen species generation, and enhanced lipid peroxidation, collectively suggesting an oxidative damage pattern with ferroptosis-like features. Based on its potent anti-Malassezia activity, a CuSO4-loaded xanthan gum/hyaluronic acid hydrogel (HG-Cu) was further developed for integrated local treatment of seborrheic dermatitis. HG-Cu exhibited viscous-flow behavior, high structural stability, and favorable biocompatibility. In a guinea pig model of M. furfur-induced seborrheic dermatitis, HG-Cu effectively suppressed fungal proliferation in lesions through sustained copper release. Histopathological analysis showed that HG-Cu markedly ameliorated skin lesions, reduced inflammatory infiltration, and promoted matrix reconstruction and skin repair by upregulating type III collagen (COL III) at the early stage and enhancing type I collagen (COL I) deposition at the later stage. Taken together, HG-Cu offers a promising localized therapeutic approach for seborrheic dermatitis by integrating sustained antifungal activity, inflammation control, and skin barrier restoration.\n\nID: 42521977\nTitle: Regulated cell death-induced coagulation dysfunction in sepsis.\nAbstract: Regulated cell death (RCD) has emerged as a pivotal upstream mediator supported by correlative preclinical and clinical evidence in the pathogenesis of sepsis-induced coagulopathy (SIC), a life-threatening complication strongly linked to increased mortality. RCD-guided phenotyping integrates pyroptosis, NETosis, ferroptosis, necroptosis, and PANoptosis pathways to systematically redefine SIC - from molecular signatures to targeted interventions. This review comprehensively examines how RCD-derived Damage-Associated Molecular Patterns (DAMPs) mediate coagulation dysfunction, explores subtype-specific biomarkers for patient stratification, and outlines phenotype-directed combination therapies. We further investigate unresolved challenges and future developments in RCD-guided precision immunomodulation, emphasizing the transformative potential of RCD-based frameworks to advance the clinical management of SIC by bridging insights from cell death and thrombosis research.\n\nID: 42521884\nTitle: Iron-ing out ferroptosis-mediated T cell dysfunction in cancer.\nAbstract: \n\nID: 42521833\nTitle: A genome-wide CRISPR screen in human prostate cancer cells reveals drivers of macrophage-mediated cell killing and positions AR as a tumor-intrinsic immunomodulator.\nAbstract: Macrophages are the most abundant immune cells in the prostate tumor microenvironment and capable of killing tumor cells, but tumor intrinsic modulators of resistance to the innate immune system are unknown. To identify genes essential for macrophage-mediated killing, we performed a genome-wide co-culture CRISPR screen and identified Androgen Receptor (AR), PRKCD, and multiple components of the NF-\u03baB pathway (IKBKB/IKBKG/CHUK) as tumor-intrinsic essential factors to allow for macrophage-mediated killing. Mechanistically, both AR and NF-\u03baB directly drive expression of PRKCD within cancer cells, functionally implicating all hits within one molecular pathway. Importantly, androgen deprivation and AR-inhibition both rendered tumor cells resistant to macrophage-mediated killing, which positions tumor-intrinsic AR signaling as a bona fide immunomodulatory pathway. Proteomic analyses showed a selective downregulation of the oxidative phosphorylation pathway in PRKCD- and IKBKG-KO cells, suggesting impaired mitochondrial function, which was confirmed by electron microscopy analyses. Finally, phosphoproteomic analyses revealed that all hits perturbing macrophage-mediated tumor cell eradication, impaired ferroptosis signaling in the tumor cells, which was confirmed transcriptionally using samples from a neoadjuvant phase II clinical trial with the AR-inhibitor enzalutamide. These data reveal immune protection from macrophages as an adverse consequence of hormonal therapy in prostate cancer patients.\n\nID: 42521170\nTitle: ROS-responsive chitosan/hyaluronan polyelectrolyte nanogels for targeted chemo-ferroptosis therapy against breast cancer.\nAbstract: Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, has emerged as a promising strategy for combination with chemotherapy in cancer treatment. However, the rational design of delivery systems capable of simultaneously inducing ferroptosis, enhancing chemotherapy efficacy, and reducing systemic toxicity remains a substantial challenge. Herein, we developed a reactive oxygen species (ROS)-responsive, ionically crosslinked chitosan/hyaluronan polyelectrolyte nanogel for targeted chemo-ferroptosis combination therapy. In this system, hyaluronic acid (HA) was first esterified with 1,2-bis (2-hydroxyethylthio) ethylene (BE) and subsequently conjugated with methotrexate (MTX) through a ROS-cleavable linkage, yielding an anionic HA-BE-MTX polymeric prodrug. Protonated chitosan (CS) served as the cationic polymeric component, while sodium tripolyphosphate (TPP) further stabilized the nanogel network through ionic crosslinking. Sorafenib (SOR), a ferroptosis inducer, was physically encapsulated during the ionotropic gelation process. The resulting R-NGMS nanogels were designed to maintain colloidal stability under physiological conditions and to undergo ROS-triggered network loosening and drug release in the tumor microenvironment, where oxidative stress is elevated. This dual-delivery system enabled ROS-responsive MTX release and SOR-mediated ferroptosis induction, thereby promoting ROS accumulation, glutathione depletion, GPX4 suppression, lipid peroxidation, and apoptosis in breast cancer cells. In vivo studies demonstrated that R-NGMS efficiently accumulated in 4T1 tumors through prolonged circulation and HA-CD44-mediated tumor targeting, achieving a tumor growth inhibition rate of 75.85% with reduced systemic toxicity compared with free drug treatment. These findings demonstrate that ionically crosslinked CS/HA-based polyelectrolyte nanogels provide an effective and selective platform for ROS-responsive chemo-ferroptosis combination therapy.\n\nID: 42521052\nTitle: Exploring Ferroptosis: Unraveling Its Potential Role in Autistic Spectrum Disorder.\nAbstract: Autism spectrum disorder (ASD) is a diverse neurodevelopmental disorder characterized by ambiguous etiological mechanisms and the absence of recognized disease-modifying pharmacotherapies. Ferroptosis, an iron-dependent and lipid peroxidation-driven mechanism of regulated cell death, has been associated with neurodevelopment and neurodegeneration, prompting interest in its potential role in ASD. This narrative review consolidates from molecular and clinical studies, animal models, and in vitro systems to assess ferroptosis as a candidate mechanistic pathway, biomarker source, and therapeutic target in ASD. Peripheral transcriptomic analyses reveal differentially expressed ferroptosis-related genes, ferroptosis-based molecular clusters, and immune-activated subtype in children with ASD, facilitating the development of ferroptosis-derived diagnostic and scoring models with modest yet reproducible discrimination. Clinical data associate maladaptive polyunsaturated fatty acid profiles, increased lipid peroxidation products, and adverse docosahexaenoic acid/arachidonic acid ratio with autistic social impairments, aligning with ferroptosis-prone conditions. In rodent models, genetic or pharmacological modulation of DDIT4-PI3K/Akt signaling, Nrf2/GPX4/xCT antioxidant systems, and ferritinophagy mitigates ASD-like social deficits, repetitive behaviors, anxiety-like phenotypes, and liver pathology. Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways, indicating subtype-specific ferroptosis resistance. These findings suggest a complex, context-dependent role of ferroptosis and ferroptosis resistance in ASD, interacting with immune dysregulation, redox imbalance, and peripheral organ involvement. Nevertheless, longitudinal and interventional studies integrating brain, peripheral, and cellular data are required to establish causality, define meaningful ferroptosis-related signatures, and evaluate the safety and efficacy of ferroptosis-modulating interventions.\n\nID: 42520529\nTitle: RRM2 promotes lung adenocarcinoma progression and is associated with ferroptosis-inducer sensitivity through the NRF2/GPX4 signaling axis.\nAbstract: Lung adenocarcinoma (LUAD) is a leading cause of cancer-related mortality, characterized by aggressive progression and therapy resistance. Ferroptosis, an iron-dependent form of regulated cell death, has emerged as a promising therapeutic avenue. However, the role of Ribonucleotide Reductase M2 (RRM2) in ferroptosis regulation and its relevance to LUAD progression remain incompletely understood. We integrated bulk transcriptomic, proteomic, WGCNA, and single-cell datasets to evaluate the clinical and biological relevance of RRM2 in LUAD. Functional validation was performed using RRM2 knockdown, ferroptosis-inducer sensitivity assays, ferroptosis-related biochemical assays, NRF2/GPX4 pathway analysis, rescue experiments, and xenograft models. RRM2 was significantly upregulated in LUAD tissues and was associated with poor overall survival. Single-cell analysis localized high RRM2 expression to a proliferative tumor cell subpopulation enriched in cell cycle- and immune-related pathways. Functionally, RRM2 knockdown suppressed LUAD cell proliferation and tumor growth and was accompanied by increased ROS, lipid ROS, Fe\u00b2\u207a, and MDA levels and decreased GSH levels. RRM2 depletion also increased ferroptosis-inducer sensitivity, with enhanced erastin and RSL3 sensitivity in A549 cells and clear RSL3 sensitization in PC9 cells. In parallel, RRM2 silencing was associated with reduced NRF2 and GPX4 expression, decreased NRF2 nuclear-to-cytosolic signal intensity, and increased ACSL4 expression. NRF2 overexpression partially restored GPX4 immunofluorescence intensity in RRM2-knockdown cells. Moreover, NRF2 overexpression or Ferr-1 treatment partially reversed the growth-suppressive effects induced by RRM2 deficiency in vitro and in vivo. RRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis. These findings support RRM2 as a candidate prognostic biomarker and a potential therapeutic target in LUAD, while the precise molecular relationship between RRM2 and the NRF2/GPX4 axis warrants further investigation.\n\nID: 42519304\nTitle: Dynamic activation of lytic cell death-related programs identifies CD14 as a candidate hub gene associated with secondary injury after spinal cord injury.\nAbstract: Secondary spinal cord injury (SCI) involves persistent inflammation, oxidative stress, and multiple forms of programmed cell death. However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures. Key findings were further evaluated using an external human SCI-related cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and published single-cell RNA-seq data. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. External validation in a human SCI-related peripheral blood cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and single-cell reanalysis further supported the upregulation of CD14 and its association with myeloid inflammatory activation and pyroptosis-, necroptosis-, and ferroptosis-related signatures. Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI.\n\nID: 42518779\nTitle: Amino Acid and Lipid Metabolism in Cancer: Mechanisms and Therapeutic Opportunities.\nAbstract: Metabolic reprogramming is a defining feature of cancer and a major contributor to immune escape. Beyond the well-defined glycolysis, dysregulated amino acid and lipid metabolism also regulate tumor growth, stress adaptation, and therapeutic resistance. Amino acids such as glutamine, arginine, tryptophan, methionine, serine, and cysteine shape biosynthesis, redox balance, one-carbon metabolism, epigenetic control, and nutrient competition in the tumor microenvironment. Lipid uptake, de novo lipogenesis, fatty acid oxidation, cholesterol remodeling, COX-PGE2 signaling, sphingolipid metabolism, and ferroptosis further influence antigen presentation, immune cell fitness, and checkpoint regulation. However, most studies still consider these metabolic axes separately, leaving the coordinated amino acid-lipid crosstalk across tumor and immune compartments insufficiently defined. This review synthesizes recent advances in amino acid metabolism, including the glutamine axis, arginine-polyamine biology, the tryptophan-kynurenine-AHR pathway, and methionine-dependent methylation programs. It then discusses lipid metabolic programs that regulate dendritic cell cross-presentation, suppressive myeloid polarization, CD8+ T cell exhaustion, PD-L1 palmitoylation, MHC-I stability, and lipid-peroxidation-linked ferroptosis. We further integrate nutrient competition, immunometabolic checkpoints, and dual metabolic targeting strategies with immune checkpoint blockade. This review provides a unified framework for identifying metabolic vulnerabilities, designing rational combination therapies and refining precision cancer immunotherapy.\n\nID: 42517944\nTitle: RNA cytosine modifications regulates musculoskeletal disorders.\nAbstract: The RNA cytosine modification (RCM), particularly 5-methylcytosine (m5C) and N4-acetylcytidine (ac4C) modification, represents a rapidly advancing frontier in recent epitranscriptomic research. These reversible modifications intervene in the process of RNA generation, thus playing a critical role in the post-transcriptional regulation of RNA, including nuclear export, ribosome assembly, translation, and stability, thereby modulating various fundamental biological processes, such as cellular proliferation, differentiation, and cell death. Musculoskeletal disorders (MSDs), including osteoarthritis (OA), osteoporosis (OP), rheumatoid arthritis (RA), osteosarcoma (OS), and intervertebral disc degeneration (IVDD), are a major class of debilitating conditions that affect the locomotor system. Emerging evidence has demonstrated that dysregulation of m5C or ac4C modification contributes significantly to MSD pathogenesis through multiple mechanisms, including chondrocyte pyroptosis, lipid droplet dynamics, macrophage polarization, osteogenic and osteoclastic differentiation, synovial hyperplasia and invasion, and tumor-associated metabolic reprogramming. Moreover, these modifications are mechanistically linked to key pathological hallmarks, such as immune cell infiltration, ferroptosis, autophagy, and aberrant mechanical compression transduction. Pharmacological targeting of m\u2075C- and ac\u2074C-regulatory enzymes has been indicated to have therapeutic potential in animal models of MSDs. Herein, we present this review that systematically addresses the molecular basis and current knowledge on the mechanisms underlying RCMs in a variety of MSDs, along with translational strategies targeting these epitranscriptomic pathways. Finally, we present our thoughts and comments on this topic.\n\nID: 42517904\nTitle: Bioactive adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres promotes spinal cord repair by suppressing inflammation, apoptosis, oxidative stress, and ferroptosis.\nAbstract: Spinal cord injury (SCI) is a devastating neurological condition characterized by severe neuronal loss, inflammation, oxidative stress, and various forms of regulated cell death that collectively impair functional recovery. The present study aimed to develop a bioactive therapeutic platform based on an adipose-derived extracellular matrix (ECM) hydrogel incorporating cytokine-releasing PLGA microspheres to promote spinal cord repair. The hydrogel was fabricated from decellularized adipose tissue and combined with microspheres encapsulating interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and glial cell line-derived neurotrophic factor (GDNF) to achieve sustained cytokine delivery. Seventy-five male Sprague-Dawley rats were randomly allocated into five experimental groups, including control, SCI, hydrogel, microsphere, and Hydrogel\u2009+\u2009Mic groups. Tissue specimens were subsequently harvested from the lesion site for further analyses. In a rat model of SCI, treatment with the cytokine-releasing microsphere-loaded hydrogel significantly improved electrophysiological conduction and locomotor recovery compared with untreated SCI animals and groups receiving individual treatments. Molecular analyses demonstrated that the combined treatment markedly suppressed the expression of pro-inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Additionally, apoptosis-related markers showed substantial modulation, characterized by decreased Caspase-3 and Bax expression and increased Bcl-2 levels. The therapy also improved the oxidative balance by increasing antioxidant markers including GSH, SOD, and CAT while reducing the lipid peroxidation marker MDA. Furthermore, ferroptosis-associated biomarkers were significantly regulated, with elevated levels of GSH, GPX4, and SLC7A11 and reduced ACSL4 expression. Histological analyses revealed significant preservation of spinal cord architecture, reduced cavity formation, enhanced neuronal survival, and decreased glial activation in animals treated with the composite hydrogel system. Collectively, these findings demonstrate that adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres provides a multifunctional therapeutic strategy that attenuates inflammation, apoptosis, oxidative stress, and ferroptosis, ultimately promoting structural and functional recovery following spinal cord injury.\n\nID: 42517861\nTitle: Senotherapeutics for Knee Osteoarthritis.\nAbstract: Osteoarthritis (OA) is a chronic disease that imposes a significant economic burden and deteriorates quality of life. Nevertheless, current therapeutic options for OA are limited to symptomatic remedies. As such, there is a high interest in novel methods for treating or preventing OA. One of the most promising medication modalities is through the clearance of cells that are cell cycle arrested but resistant to apoptosis, termed senescent cells. Additionally, these cells are also resistant to alternative programmed cell death modes, such as ferroptosis and pyroptosis. Senescent cells tend to accumulate with age due to increasing cellular and genetic damage. These cells can release inflammatory factors and signaling molecules termed senescence-associated secretory phenotype (SASP). In addition to triggering an inflammatory milieu in joints, SASP can also induce senescence in other cells through autocrine signaling. It has been shown via in vitro and in vivo tests that clearance of senescent cells through a class of drugs known as senolytics, or neutralization of SASP with senomorphics, can improve OA pathogenesis. Following these results, several clinical trials have been conducted to evaluate the efficacy of senotherapeutics against knee OA. Yet there remains a need for a comprehensive assessment of safety and optimization of senotherapeutic treatment regimens for knee OA. To this end, a better understanding of molecular mechanisms behind chondrocyte senescence and knee OA pathogenesis is necessary. Identification of novel compounds that can specifically target chondrocyte senescence pathways can assist in developing more effective therapies against OA.\n\nID: 42517390\nTitle: Targeting Ferroptosis-associated Histone Acylation for Amelioration of Neurological Disease.\nAbstract: Ferroptosis is an iron-dependent, lipid peroxidation-driven form of programmed cell death. There is substantial evidence supporting the critical role of ferroptosis in multiple neurological diseases, including stroke, Alzheimer's disease, Parkinson's disease, epilepsy, and traumatic brain injury. Histone acylation, an important epigenetic mechanism, effectively regulates ferroptosis. To date, the regulation of ferroptosis by histone acylation in neurological diseases has rarely been summarized. Therefore, this review discusses the key mechanisms by which histone acylation regulates ferroptosis, including iron metabolism, antioxidant defense, and lipid peroxidation. Additionally, we summarize the latest advances in understanding the role of histone acylation in ferroptosis and its relation to the emerging hallmarks of neurological diseases. Furthermore, we provide the prospect of targeting key regulatory factors of histone acylation, such as writers, erasers, and readers, for potential therapeutic strategies to ameliorate neurological diseases.\n\nID: 42517186\nTitle: Mitochondrial Dysfunction at the Crossroads of Necroptosis: Mechanisms, Molecular Mediators, and Therapeutic Opportunities.\nAbstract: The conceptual landscape of cell death has evolved beyond the traditional dichotomy of apoptosis and necrosis to encompass diverse regulated pathways including necroptosis, autophagy, ferroptosis, and pyroptosis. Necroptosis, a caspase-independent inflammatory form of programmed cell death, has emerged as a critical driver of the pathogenesis of cardiovascular disorders, neurodegenerative diseases, and cancer. Concurrently, our understanding of mitochondrial biology has undergone a paradigm shift: mitochondria are no longer viewed merely as bioenergetic powerhouses, but as dynamic signalling hubs that orchestrate metabolic reprogramming, cellular homeostasis, and ultimate cell fate decisions. In this regard, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This review delineates the mechanistic interplay between necroptosis and mitochondrial dysfunction and systematically analyzes the key molecular mediators and pathological pathways through which mitochondrial dysregulation drives necroptotic activation. Furthermore, this review identifies actionable therapeutic targets and translational strategies for modulating necroptosis in related diseases.\n\nID: 42517156\nTitle: Bibliometric Trends in Inflammasome\u2011Driven Pyroptosis and Cardiovascular Disease.\nAbstract: This bibliometric study provides the first comprehensive synthesis of inflammasome\u2011driven pyroptosis research in cardiovascular disease (CVD), systematically mapping its evolution. Pyroptosis, an inflammatory form of programmed cell death triggered by inflammasome activation, plays a critical role in various CVDs, including hypertension, ischemia\u2011reperfusion injury (I/R injury), atherosclerosis, and heart failure (HF). Despite rapid growth of the literature, no bibliometric analysis has specifically focused on this area. Data were retrieved from the Web of Science Core Collection (1998-April 27, 2025). Bibliometric and visual analyses were performed using CiteSpace and VOSviewer to examine publication trends, country/region, funding agency, institution, author, journal, subject category, co\u2011cited reference, keyword co\u2011occurrence, and emerging hotspots. A total of 4,511 documents (2,918 original articles and 1,593 reviews) were included. China contributed 2,259 publications (50.1% of total) with 56,326 citations; the United States contributed 1,022 publications (22.7%) with 79,057 citations and the highest country\u2011level h\u2011index (147); and Italy ranked third with 290 publications (6.4%). Harvard University and its affiliated institutions led in both publication quantity and impact (h\u2011index, citations per article). Keyword co\u2011occurrence identified four clusters: pyroptosis mechanisms, NLRP3 inflammasome, signaling pathways, and CVDs. Recent bursts (2024\u20112025) highlight \"pyroptosis\" and \"ferroptosis\" as emerging frontiers. This bibliometric study identifies NLRP3 as the central research focus in inflammasome\u2011driven pyroptosis research, with the strongest citation burst. The findings reveal a shift from basic mechanistic studies toward translational research, highlighting emerging priorities such as the crosstalk between pyroptosis and ferroptosis and the need for patient stratification in future clinical trials.\n\nID: 42517086\nTitle: Berberine-induced ferroptosis as a novel anti-cancer strategy: Molecular, epigenetic and translational perspectives.\nAbstract: Cancer cells frequently evade therapies that depend on apoptosis, necessitating the exploration of alternative cell death mechanisms. Ferroptosis, an iron-dependent regulated cell death characterized by lethal lipid peroxidation, has emerged as a promising strategy for cancer treatment. Recent studies have identified berberine, an isoquinoline alkaloid derived from Coptis chinensis and Berberis species, as an inducer of ferroptosis in various malignancies through its multitarget effects. This review systematically elucidates the molecular pathways through which berberine induces ferroptosis. These pathways include the inhibition of the System Xc-/glutathione/glutathione peroxidase 4 antioxidant axis, disruption of iron homeostasis via ferritinophagy, inhibition of mitochondrial complex I, and regulation of the upstream regulators p53, nuclear factor erythroid 2-related factor 2, and Gli1/signal transducer and activator of transcription 3 axis. Evidence specific to various cancer types, including nasopharyngeal, lung, colorectal, gastric, hepatocellular, pancreatic, prostate cancer, and osteosarcoma, was critically evaluated. Translational strategies, such as combination therapy, nanodelivery systems, and machine learning-directed structural optimization, have been examined. Additionally, the challenges of low bioavailability, resistance to ferroptosis, and complex immunological responses are discussed. Preclinical evidence suggests that berberine exhibits significant epigenetic activity, including the inhibition of DNA methyltransferases (DNMT1/DNMT3), histone modifications (H3K9me3 via SETDB1, H3K27me3 via EZH2), and modulation of oncogenic/tumor-suppressor microRNAs (e.g., miR-21, miR-155). These actions enhance its ferroptotic effects and may synergistically increase the sensitivity of cancer cells to lipid peroxidation. Although primarily based on preclinical findings, these epigenetic mechanisms represent a crucial and underexplored aspect of berberine's anticancer potential.

Ferroptosis, an iron-dependent, non-apoptotic form of regulated cell death characterized by the lethal accumulation of lipid peroxides, represents a pharmacologically significant vulnerability in cancers that are resistant to apoptosis and tolerant to drugs. The resistance to ferroptosis, induced by the aberrant overexpression of the epigenetic enzyme histone deacetylases (HDACs) and the sustained transcriptional activity of key antiferroptotic targets, particularly GPX4 and SLC7A11, is enforced through epigenetic mechanisms. This review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways. These pathways include the transcriptional silencing of SLC7A11 and subsequent glutathione depletion, disruption of intracellular iron homeostasis via ferroportin downregulation, enhancement of mitochondrial ROS-induced lipid peroxidation, and suppression of the HDAC3-NRF2-GPX4 antiferroptotic axis. The specific roles of HDAC1, HDAC3, and HDAC10 in colorectal, lung, gastric, and hematological cancers are elucidated. Additionally, the review discusses hybrid molecules of HDAC-ferroptosis, combination strategies with GPX4 inhibitors, and immunochemotherapy. Considerations such as isoform selectivity, biomarker development, and clinical translation are addressed, highlighting HDAC inhibitor-mediated ferroptosis sensitization as a promising strategy to overcome drug resistance in cancer.

However, its associated cardiotoxicity poses a major challenge for its therapeutic use. There are numerous studies exploring the underlying cellular mechanisms behind Dox-induced cardiotoxicity. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity. Under normal physiology, cardiomyocytes maintain a highly regulated iron homeostasis, while the polyunsaturated fatty acid-rich membrane also renders it susceptible to peroxidation, a hallmark of ferroptosis. Dox-induced cardiotoxicity disrupts the coordinated control of iron metabolism, generating reactive oxygen species, propagating lipid peroxidation, and impairing mitochondrial function. Progressive structural damage and functional loss of cardiomyocytes culminate in permanent cardiac cell death. Therefore, targeting regulatory nodes of ferroptosis may be beneficial for ameliorating Dox-induced cytotoxicity. However, it is still not clear whether the ferroptotic process merely acts as an initiator or can further act as an amplifier to upregulate the downstream signaling molecules in this cell death cascade. This review offers an overview of perspectives on the ferroptotic pathway and introduces readers to a novel driver-amplifier concept.

Because of its proximity to the plasma membrane, the outermost cellular barrier, CS can interact with the phospholipids forming the structural scaffold of this cellular membrane. We hypothesise that the lipid composition of the plasma membrane, and specifically the exposure of phosphatidylserine (PS) lipids (an event that is detected in cancer cells and also associated to apoptosis and inflammation), affects the structural conformation of CS at the cell surface. Experiments We combined experimental data obtained with different techniques, i.e., quartz crystal microbalance with dissipation monitoring, neutron reflectometry and infrared spectroscopy, with molecular dynamics (MD) simulations to investigate the adsorption of CS at the surface of lipid bilayers prepared with either phosphatidylcholine (PC) lipids or a mixture of PC and PS lipids. Experiments were designed to identify the molecular groups that are involved in the CS-lipid interaction. Findings Our results indicate that CS adsorbs and remains stably attached to the lipid bilayer without PS lipids, due to stabilising interactions between the negatively charged sulphate groups on CS and positively charged choline groups within PC. The addition of POPS strongly reduces the CS-bilayer association: detecting experimentally CS chains attached to the bilayer was challenging, and the MD simulations suggest a weaker binding of CS to a PC-PS membrane.\n\nID: 42526136\nTitle: The role and mechanism of S1PR2 in endothelial dysfunction and aortic lesions during gestational diabetes mellitus.\nAbstract: This study investigated the role of S1PR2 in gestational diabetes mellitus (GDM)-associated endothelial dysfunction and aortic lesions, and its relationship with advanced glycation end-products (AGEs) and the RhoA/ROCK1/eNOS pathway. Placental tissues and serum samples were collected from patients with GDM and healthy pregnant women to assess S1PR2 expression and AGEs levels. HUVECs were treated with high glucose (HG), osmotic control medium, JTE-013, S1PR2 siRNA, S1PR2 overexpression plasmid, or AGEs-BSA. Cell viability, apoptosis, endothelial permeability, reactive oxygen species (ROS), nitric oxide (NO), and RhoA/ROCK1/eNOS pathway proteins were examined. A GDM rat model was established using a high-fat diet combined with low-dose streptozotocin, followed by pyridoxamine or JTE-013 treatment. S1PR2 expression and serum AGEs levels were increased in GDM samples. HG impaired HUVEC viability, increased apoptosis, permeability, and ROS production, reduced NO content, activated RhoA/ROCK1 signaling, and decreased eNOS phosphorylation, while osmotic control showed no obvious effect. JTE-013 and S1PR2 knockdown alleviated endothelial injury, whereas S1PR2 overexpression aggravated these changes. AGEs-BSA upregulated S1PR2, increased ROS, and decreased NO. In GDM rats, pyridoxamine and JTE-013 reduced serum AGEs, aortic lipid deposition, vascular injury, and S1PR2/RhoA/ROCK1 pathway activation. S1PR2 promotes high-glucose-induced endothelial dysfunction and GDM-related aortic lesions, partly through the RhoA/ROCK1/eNOS axis. AGEs may contribute to S1PR2 upregulation, suggesting that AGE formation and S1PR2 are potential targets for GDM-associated vascular injury.\n\nID: 42526131\nTitle: Design, synthesis, and evaluation of anti-solid-tumor activity of niclosamide-based STAT3/HDAC dual-target inhibitors.\nAbstract: Inspired by reports that HDAC blockade can trigger compensatory activation of the LIFR-JAK1-STAT3 axis in solid tumors, we designed and synthesized a series of niclosamide-based STAT3/HDAC dual-target inhibitor candidates by incorporating a SAHA-derived hydroxamate zinc-binding group into the pleiotropic, STAT3-modulating niclosamide scaffold. Biological evaluation identified NS06 as the best-balanced analogue, with IC50 values of 1.49 and 1.41\u00a0\u03bcM against MDA-MB-231 and HCT116 cells, respectively. Mechanistic studies showed that NS06 bound STAT3 in vitro (SPR, KD\u00a0=\u00a05.82\u00a0\u03bcM), suppressed STAT3 phosphorylation, and inhibited HDAC1, HDAC3, and HDAC6 with IC50 values of 129.1, 451.2, and 230.4\u00a0nM, respectively, while showing limited inhibition of HDAC4 and HDAC11 in the primary screen. NS06 also increased histone H3 acetylation, induced apoptosis, and inhibited migration and colony formation. In addition, NS06 retained antiproliferative activity in a 3D tumor spheroid model and showed improved Caco-2 permeability together with moderate liver microsomal stability (t1/2\u00a0\u2248\u00a048.6\u00a0min in rat liver microsomes). Docking and 100-ns molecular dynamics simulations further supported chemically plausible binding modes in the HDAC1 catalytic pocket and the STAT3 SH2 domain. Overall, these findings support niclosamide as a tractable scaffold for mechanism-driven STAT3/HDAC dual-target inhibitor design and identify NS06 as a promising lead for further optimization against solid tumors.\n\nID: 42525869\nTitle: Modulation of Cyst Growth in Autosomal Dominant Polycystic Kidney Disease: Mechanistic Insights and Therapeutic Opportunities.\nAbstract: Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common inherited kidney disorders and is characterized by the progressive formation and expansion of fluid filled cysts, ultimately leading to kidney failure. Although caused by reduced dosage of the polycystin proteins, the disease phenotype arises from a broad disruption of epithelial physiology rather than a single linear pathway. Loss of polycystin function destabilizes epithelial homeostasis and sensitizes cyst lining cells to proliferative and secretory cues. A central consequence is the emergence of a self reinforcing signaling environment in which cyclic AMP, Ca2+, and purinergic pathways amplify one another, promoting chloride driven fluid secretion and epithelial proliferation. In parallel, cyst epithelia exhibit disturbed cell turnover, including altered proliferation, apoptosis, autophagy, and ferroptotic stress, which reshape luminal architecture and sustain a pro secretory microenvironment. Metabolic reprogramming, characterized by enhanced glycolysis, mitochondrial dysfunction, and redox imbalance, provides energetic support for these processes and further strengthens proliferative and secretory signaling. Hypoxia inducible factor 1\u03b1 (HIF 1\u03b1) integrates hypoxic, metabolic, and mechanical cues into transcriptional programs that reinforce cyst expansion. This review synthesizes these interconnected mechanisms and highlights potential therapeutic strategies, including restoration of polycystin expression, modulation of cAMP and purinergic signaling, inhibition of chloride secretion, metabolic targeting, and HIF 1\u03b1 pathway intervention. Together, these insights support a model in which cyst growth arises from mutually reinforcing signaling, metabolic, and transcriptional programs. Effective disease modification will likely require multi nodal therapeutic approaches that address this integrated network.\n\nID: 42525531\nTitle: High Glucose Supplementation Aggravates Experimental Autoimmune Epididymo-orchitis via Localized Th17 Skewing in the Male Reproductive Tract.\nAbstract: Chronic epididymo-orchitis contributes significantly to male infertility through immune cell infiltration and pro-inflammatory cytokine elevation. High glucose intake promotes Th17 differentiation and autoimmunity, but its effects on autoimmune testicular inflammation remain unclear. To determine whether chronic high glucose supplementation exacerbates experimental autoimmune epididymo-orchitis (EAEO), impairs spermatogenesis, and drives CD4+ T-cell dysregulation, particularly Th17 polarization, in the reproductive tract. EAEO was induced in male C57BL/6 mice with or without chronic 10% glucose supplementation in drinking water. Sperm parameters, ROS levels, apoptosis, and histopathology were evaluated. CD4+ T-cell subsets (Th1, Th17, Treg, TNF-\u03b1+ effector memory) were quantified by flow cytometry in testis, epididymis, spleen, and testicular inguinal lymph nodes (iLN) at days 30, 60, and 90 post-immunizations. High glucose intake accelerated EAEO progression, markedly worsening sperm concentration and motility, elevating sperm ROS, increasing germ cell apoptosis, and causing severe histopathological damage. In the reproductive tract, glucose induced an upward trend of CD4+ T cells and late-phase selective Th17 skewing (days 60-90), with significant IL-17A+CD4+ Teff increases and accompanying TNF-\u03b1+CD4+CD44+ Teff upregulation, while IFN-\u03b3+ Th1 responses remained modest. These pro-inflammatory changes were strictly localized, with no significant Th17, Th1, Treg, or TNF-\u03b1 alterations in spleen or iLN. Chronic high glucose exacerbates EAEO by intensifying oxidative stress, apoptosis, and tissue injury while promoting a late-phase, tissue-restricted Th17-biased CD4+ T-cell response in the testis and epididymis. These findings reveal a metabolic-immune axis that may accelerate immune-mediated male subfertility via localized Th17 mechanisms.\n\nID: 42525490\nTitle: Formulation and Evaluation of Etoposide-loaded Dextran polymeric nanoparticles fabricated with Hyaluronic acid for the treatment of colorectal cancer using network pharmacology, in-silico, in-vitro, and in-vivo approaches.\nAbstract: Etoposide (ETP), a Biopharmaceutics Classification System class IV drug with poor aqueous solubility, demonstrates limited therapeutic efficacy against colorectal cancer (CRC) because of inferior absorption and off-target effects. To deliver drugs specifically to cancer cells that overexpress CD44, this study developed hyaluronic acid (HA)-functionalized dextran (DEX) polymeric nanoparticles (ETP-DEX-HA-NPs). Optimised nanoparticles (174.7\u2009\u00b1\u20093.2\u2009nm, -12.83\u2009\u00b1\u20091.1\u2009mV) demonstrated significant entrapment efficiency (62.75\u2009\u00b1\u20092.32%) and drug loading (55.64\u2009\u00b1\u20093.86%), with partial amorphization validated by FTIR, XRD, Raman, NMR, and DSC analyses. The formulation exhibited prolonged, pH-responsive release, markedly improved solubility (P < 0.05), and greater cytotoxicity in HCT-116 cells (IC50: 6.83\u2009\u00b1\u20090.35 \u00b5g/mL compared to 41.89\u2009\u00b1\u20091.02 \u00b5g/mL for free ETP). It facilitated CD44-mediated uptake, enhanced apoptosis, induced G2/M arrest, elevated ROS production, and inhibited migration while preserving biocompatibility. Network pharmacology and molecular docking identified key interactions with CRC-related targets (e.g., TOP2A, BCL2). ETP-DEX-HA-NPs offer a promising, targeted nanoplatform that addresses ETP's limitations, boosting therapeutic efficacy and safety for CRC treatment.\n\nID: 42525372\nTitle: Quercetin exerts radioprotective effects against radiation-induced intestinal injury with involvement of the PI3K-AKT/Caspase-3 axis.\nAbstract: Radiation-induced intestinal injury (RIII) significantly limits the efficacy of abdominal and pelvic radiotherapy while also impairing patient quality of life. This condition is primarily driven by excessive reactive oxygen species (ROS) and dysregulation of Caspase-dependent apoptosis. Quercetin (QUE), a natural antioxidant flavonoid, exhibits radioprotective potential; however, the key signaling pathways it employs to regulate radiation-induced apoptosis remain to be elucidated. In vitro studies, IEC-6 cells (1-10\u00a0\u00b5g/mL QUE pretreatment followed by 0-8\u00a0Gy X-ray exposure) were conducted to analyze proliferation, clonogenic survival, ROS levels, apoptosis, and expression of RIII-related proteins and genes. Network pharmacology identified 47 overlapping targets associated with QUE and RIII, with AKT1 and CASP3 identified as hub targets, and the PI3K-AKT pathway recognized as a key regulatory pathway. A Caspase-3/7 inhibitor (HY-103346, H10) and AutoDock-Vina docking analysis were used to explore the involvement of Caspase-3-related apoptotic signaling. In vivo experiments using Drosophila melanogaster (W1118) involved groups subjected to control, 50\u00a0Gy irradiation alone, or 50\u00a0Gy combined with 1/5/10/50 \u00b5g/mL QUE. Lifespan, locomotor capacity, and intestinal ROS levels were assessed, including validation with DCP-1RNAi transgenic flies (DCP-1: Drosophila Caspase-3 homolog). In vitro findings revealed that QUE enhanced the viability of irradiated IEC-6 cells, reduced ROS and apoptosis, upregulated anti-apoptotic markers (p-AKT, p-PI3K and p-mTOR), and downregulated pro-apoptotic markers (cleaved-Caspase-3 and Cytochrome C), while H10 inhibited the effects of QUE. Molecular docking suggested a potential interaction between QUE and Caspase-3 through hydrogen bonds and hydrophobic interactions to inhibit its activation. In vivo, pre-irradiation gavage of 10\u00a0\u00b5g/mL QUE mitigated RIII in Drosophila, an effect that was abolished in DCP-1 knockdown flies. In summary, QUE protects against RIII by scavenging ROS and modulating apoptosis-related signaling, with evidence supporting the involvement of the PI3K-AKT/Caspase-3 axis, with the PI3K-AKT/Caspase-3 axis identified as central to these protective effects. This study underscores the clinical potential of QUE for RIII and offers insights into the targeting of apoptosis for radioprotection.\n\nID: 42525347\nTitle: KLF4 in Parkinson's Disease: Decoding the Molecular Puzzle of Neuroinflammation, Oxidative Stress, and Emerging Therapies.\nAbstract: Parkinson's disease (PD) is the most prevalent neurodegenerative movement condition. Tremors, stiffness, bradykinesia/akinesia, and postural instability are its primary motor symptoms; nevertheless, the clinical features also include non-motor and additional motor symptoms. Kr\u00fcppel-like factor 4 (KLF4), a zinc finger transcription factor, is present in several human tissues and performs a range of cell-dependent regulatory actions. Various neurological diseases, such as PD, Alzheimer's disease (AD), and Huntington's disease (HD), have been linked to KLF4, which regulates some neurophysiological and neuropathological processes in the brain. Recent data indicate that KLF4 plays a crucial regulatory role in the neurophysiological and neuropathological processes underlying PD, suggesting that it might be a viable therapeutic target for neurodegenerative diseases. This review focuses on the potential molecular mechanism underlying KLF4-mediated neuroinflammation, oxidative stress, mitochondrial dysfunction, and apoptosis. KLF4-mediated pathways are clarified by the information gathered here, and targeting them appears to be a viable therapeutic strategy for treating PD. Nevertheless, there is insufficient information on this subject, and more investigations are needed to fully understand the translational significance of the KLF4-oriented therapeutic strategy in PD.\n\nID: 42525298\nTitle: The impact of umbilical cord blood platelet lysate on human corneal endothelium during organ culture.\nAbstract: To evaluate whether umbilical cord blood platelet lysate (UCB-PL) can preserve the morphology and characteristics of human corneal endothelial cells during organ culture and serve as a xeno-free alternative to fetal bovine serum (FBS). Paired human donor corneas were cultured for 28\u00a0days in \u03b1-MEM-based medium supplemented with either 2% FBS or 2% UCB-PL. Endothelial morphology, cell density, viability, and mosaic regularity were assessed at predefined time points. Metabolic activity was evaluated by measuring pH, glucose, and lactate concentrations in the culture media. Endothelial integrity, apoptosis, and proliferation were analyzed by whole-mount immunofluorescence staining for ZO-1, Na\u207a/K\u207a-ATPase, caspase-3, and Ki-67. Corneas stored in UCB-PL-supplemented medium demonstrated endothelial morphology, cell density decline, and viability comparable to those observed in FBS-supplemented medium throughout the culture period. No significant differences were detected between groups at any time point. Metabolic analysis showed sustained glucose availability and expected lactate accumulation in both media, without evidence of nutrient depletion. Immunofluorescence confirmed preserved endothelial junctional organization and pump protein expression, with no signs of endothelial apoptosis or proliferation. In this pilot feasibility study, UCB-PL supported preservation of human corneal endothelial morphology and endothelial-associated protein expression during organ culture and demonstrated similar trends to FBS. These findings support further investigation of UCB-PL as a potential xeno-free alternative for corneal storage media.\n\nID: 42525295\nTitle: Integrated bioinformatics and experimental validation reveal that kaempferol ameliorates intervertebral disc degeneration via dual anti-inflammatory and anti-aging pathways.\nAbstract: Intervertebral disc degeneration (IVDD) is a degenerative disease characterized by degradation of the extracellular matrix (ECM) in the nucleus pulposus, disruption of the fibrous ring structure, and imbalance of the inflammatory microenvironment. It is the main cause of chronic low back pain. Its pathogenesis is closely related to cellular aging and immune inflammation. Aging nucleus pulposus cells release pro-inflammatory factors such as IL-6 and TNF-\u03b1 through the secretion of senescence associated secretory phenotype (SASP), recruiting M1 macrophages to infiltrate and forming a vicious cycle of \"aging inflammation matrix destruction.\" This study systematically analyzed the molecular mechanism by which kaempferol improves IVDD through multi-target regulation by integrating bioinformatics analysis, animal experiments, and cell models. Bioinformatics screening revealed significant abnormal expression of genes such as AURKB, CCNB1, AXL, NEK6, and PTK2 in IVDD degenerated tissues. Downregulation of CCNB1 induced G2/M phase arrest by inhibiting CDK1 activity, while activation of GSK3B inhibited the Wnt signaling pathway by phosphorylating \u03b2-catenin, exacerbating ECM catabolism. Proteomics further confirms that the NOX4 mediated ROS-p38 MAPK pathway promotes cell apoptosis and SASP secretion. Immune infiltration analysis showed that M1 macrophages were significantly enriched in degenerated intervertebral discs, and their secreted IL-6 and TNF-\u03b1 amplified the inflammatory cascade by activating the NF-\u03ba B pathway. Animal experiments have shown that intervention with kaempferol can partially restore the intervertebral disc height index (DHI), downregulate the levels of IL\u20111\u03b2 and TNF\u2011\u03b1, upregulate the expression of CCNB1 and AURKB (which were downregulated in the IVDD model), thereby alleviating G2/M phase arrest and promoting cell cycle progression, inhibit AXL and PTK2, and reduce macrophage infiltration. Mechanistically, kaempferol inhibits NOX4 activity by clearing ROS, blocking the vicious cycle of oxidative stress\u2011inflammation; by regulating the NEK6/NF\u2011\u03baB axis, the expression of MMP\u20113 and ADAMTS\u20114 is reduced, delaying ECM degradation; and improve the immune microenvironment by promoting macrophage polarization towards the M2 phenotype. In addition, kaempferol can reverse the metabolic imbalance mediated by GSK3B. This study reveals for the first time that kaempferol upregulates core gene networks such as AURKB and CCNB1 while suppressing AXL through the \"anti\u2011inflammatory anti\u2011aging\" dual pathway, thereby breaking the \"aging\u2011immunity\" crosstalk and restoring cell cycle homeostasis, providing a new strategy for natural compound intervention in IVDD treatment.\n\nID: 42525287\nTitle: Rutin attenuates acrylamide-induced oxidative liver injury.\nAbstract: Acrylamide (ACR) is an important chemical raw material, and its toxic effects have been confirmed in vitro and in vivo. However, only a few studies have investigated ACR-induced liver injury. As a naturally occurring flavonoid widely distributed across the plant kingdom, rutin (Rut) possesses notable pharmacological properties. This study aimed to demonstrate its therapeutic potential in mitigating ACR-induced hepatic injury in rats. Accordingly, an intervention model was established to explore the mechanistic basis of the protective effects of Rut against ACR-induced liver injury. The experimental design comprised five cohorts (n\u2009=\u200910), consisting of 50 male Sprague-Dawley rats randomly assigned to each group: (1) Control (0.5% CMC-Na\u2009+\u2009ddH2O), (2) ACR (20\u00a0mg/kg/day via gavage), (3) Rut-L (100\u00a0mg/kg)\u2009+\u2009ACR, (4) Rut-M (200\u00a0mg/kg)\u2009+\u2009ACR, and (5) Rut-H (400\u00a0mg/kg)\u2009+\u2009ACR. Interventions lasted for 21 days. The body weights of the animals were monitored daily. The liver coefficient (liver weight/body weight) was calculated after euthanasia. Commercial assay kits were used to determine serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities and hepatic Superoxide Dismutase (SOD), Glutathione (GSH), and Malondialdehyde (MDA) levels. Histopathological changes were assessed using Hematoxylin and eosin and Masson staining. Tumor Necrosis Factor-\u03b1 (TNF-\u03b1) and cleaved caspase-3 expression levels were analyzed using immunohistochemistry. Compared with the Control group, ACR exposure attenuated the rate of body weight accrual (P\u2009<\u20090.05) and the liver-to-body weight ratio (P\u2009<\u20090.05), elevated serum ALT (\u219134.8%, P\u2009<\u20090.05) and AST (\u219147.7%, P\u2009<\u20090.05), decreased hepatic SOD (\u219348.9%, P\u2009<\u20090.05) and GSH (\u219317.7%, P\u2009<\u20090.05), and increased MDA (\u219138.8%, P\u2009<\u20090.05). High-dose Rut reversed these effects by increasing body weight gain (P\u2009<\u20090.01), liver coefficient (\u219129.4%, P\u2009<\u20090.05), SOD (\u219132.1%, P\u2009<\u20090.05), and GSH (\u219112.1%, P\u2009<\u20090.05), while reducing ALT (\u219322.9%, P\u2009<\u20090.01), AST (\u219316.8%, P\u2009<\u20090.01), and MDA (\u21939.0%, P\u2009<\u20090.05) levels. Histopathological analysis demonstrated reduced hepatocyte necrosis and collagen deposition in the Rut-treated group. Immunohistochemistry revealed that ACR increased TNF-\u03b1 (\u2191121.4%, P\u2009<\u20090.001) and cleaved caspase-3 (\u219197.8%, P\u2009<\u20090.001) expression, which was suppressed by Rut (TNF-\u03b1: \u219348.2%, P\u2009<\u20090.01; cleaved caspase-3: \u219339.5%, P\u2009<\u20090.01). The effect sizes (Cohen's d) ranged from 1.2 to 3.6, indicating robust effects. Rut exhibits a marked protective effect against ACR-induced hepatic injury. Therefore, Rut may be considered a potential agent for preventing ACR-induced liver injury in rats.\n\nID: 42525181\nTitle: Age-related differences in liver damage and inflammation after femoral osteotomy.\nAbstract: Fractures of long bones such as the femur are a common and serious health concern in the elderly, triggering immune responses essential for healing but also affecting remote organs like the liver. With age, the risk of fractures and immune imbalance increases, raising the likelihood of organ damage, infections, and mortality. To better understand age-dependent hepatic responses to bone injury, this study investigates early immune responses in the liver following femoral osteotomy, used here as a reproducible model of fracture. In a mouse model, young (17-26\u00a0weeks old) and aged (64-72\u00a0weeks old) male C57BL/6J mice received a femoral osteotomy with external fixation (Fx) or a corresponding sham procedure. After 24\u00a0h, inflammation, apoptosis, tissue damage, and immune responsiveness of the liver were analyzed. Aged sham animals exhibited a higher inflammatory state in sham-operated animals (neutrophil infiltration, tumor necrosis factor (TNF), interleukin (IL)-1b, chemokine (C-X-C motif) ligand 1 (CXCL1)), without corresponding increases in caspase-3-positive cells, activation of c-Jun N-terminal kinase (JNK), expression of sirtuin (SIRT) 1 or 3, or the receptor for advanced glycation end products (RAGE). Fx did not increase liver damage in young mice but showed a trend toward greater damage in aged mice. Fx significantly increased hepatic neutrophil infiltration and CXCL1 as well as TNF concentrations in both age groups. Aged mice showed weaker activation of pro- and anti-inflammatory signaling pathways after osteotomy, with reduced RAGE expression, JNK activation, and less pronounced induction of SIRT1 and SIRT3. In summary, femur osteotomy induced liver inflammation in both young and aged animals; however, older animals exhibit higher apoptosis and a superimposed inflammatory response on top of already elevated baseline inflammation in sham conditions. Further, they did not adequately activate key regulators like RAGE, SIRT1, and JNK, which coordinate inflammation and repair. Observed dysregulations may underlie the increased vulnerability to post-traumatic complications in the elderly. Understanding these age-related deficits is essential to improving therapeutic strategies.\n\nID: 42525172\nTitle: The multifaceted role of SOCS3 in colorectal cancer: molecular mechanisms and clinical implications.\nAbstract: Colorectal cancer (CRC) remains a major cause of cancer-related mortality, particularly in advanced or metastatic disease. The Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway mediates cytokine-driven signaling, and its persistent activation contributes to tumor growth, invasion, immune escape, and therapeutic resistance. Suppressor of cytokine signaling 3 (SOCS3) is a key negative regulator of cytokine and growth factor signaling, especially the IL-6/JAK/STAT3 axis. This review summarizes the structure and physiological functions of SOCS3 and discusses its dysregulation in CRC initiation, progression, metastasis, prognosis, and treatment response. Current evidence indicates that SOCS3 is frequently downregulated in CRC through promoter methylation and post-transcriptional regulation by oncogenic microRNAs, leading to sustained STAT3 activation, increased proliferation, reduced apoptosis, and enhanced invasiveness. SOCS3 also interacts with MEK/ERK and PI3K/AKT signaling and influences the tumor microenvironment by regulating T-cell balance, PD-L1 expression, and macrophage activity. Clinically, reduced SOCS3 expression has been associated with lymph node metastasis, advanced TNM stage, and poorer prognosis, whereas higher SOCS3 levels may correlate with improved outcomes and chemosensitivity. Emerging therapeutic strategies include epigenetic modulation, JAK/STAT pathway inhibition, regulation of IL-6 signaling in adoptive T-cell therapy, AhR/IL-22 modulation, and FXR activation. Further translational studies are needed to validate SOCS3 as a biomarker and therapeutic target in CRC.\n\nID: 42525155\nTitle: LncRNA DNM3OS suppresses proliferation, invasion, and epithelial-mesenchymal transition in cervical cancer cells via miR-454-3p.\nAbstract: Cervical cancer (CC) persists as a major contributor to cancer-related deaths in the female population. Long non-coding RNAs have shown potential as biomarkers in tumors, but the function of DNM3OS in CC is unclear. This study investigates the prognostic value of DNM3OS in CC and its functional effects in tumor cells, aiming to identify a promising biomarker for this cancer. DNM3OS expression was measured in tumor and normal tissues from 152 patients with CC using RT-qPCR, and its association with progression-free survival and clinical parameters was analyzed. The role of DNM3OS on proliferation, invasion, apoptosis, and epithelial-mesenchymal transition (EMT) in CC cells was examined following overexpression or knockdown. The binding between miR-454-3p and DNM3OS was verified, and functional rescue experiments were conducted by upregulating miR-454-3p. DNM3OS was significantly downregulated in CC tissues, and its low expression was associated with larger tumor size, lymph node metastasis, and advanced FIGO stage. DNM3OS acted as an independent factor for prognosis, with its low expression correlating with poor progression-free survival in CC patients. DNM3OS directly bound to miR-454-3p. Overexpression of DNM3OS suppressed the proliferation, EMT, and invasion of CC cells, while promoting apoptosis. These antitumor effects were partially counteracted by miR-454-3p overexpression. Downregulation of DNM3OS predicts poor prognosis in CC, and DNM3OS suppresses the biological behavior of tumor cells by sponging miR-454-3p. DNM3OS may serve as a prognostic biomarker for CC.\n\nID: 42525141\nTitle: SOX9 knockdown alleviates A\u03b21\u201142\u2011induced neuroinflammation by regulating microglial polarization via inactivation of the ASK1/JNK signaling pathway.\nAbstract: Neuroinflammation driven by microglial polarization imbalance plays a key role in A\u03b2-induced neuronal injury, a core pathological feature of Alzheimer's disease (AD). The transcription factor SOX9 has been linked to AD progression, but its mechanism remains unclear. SOX9 expression was measured in peripheral blood mononuclear cells from 24 patients with AD and 24 age-matched healthy controls and correlated with Montreal Cognitive Assessment scores. An A\u03b21-42-stimulated BV-2 cell model was used to investigate the effects of SOX9 and apoptosis signal-regulating kinase 1 (ASK1) on microglial polarization. Neuronal injury was evaluated in a BV-2/SH-SY5Y co-culture system. The transcriptional regulation of ASK1 by SOX9 was examined using dual-luciferase reporter and chromatin immunoprecipitation assays. ASK1 overexpression and the ASK1 inhibitor GS-4997 were used for mechanistic validation. SOX9 expression was increased in peripheral blood mononuclear cells from patients with AD and was negatively correlated with cognitive function. SOX9 was also upregulated in A\u03b21-42-stimulated BV-2 cells. SOX9 overexpression enhanced M1-associated inflammatory markers and reduced M2-associated markers, whereas SOX9 knockdown produced the opposite effects. In the co-culture system, SOX9 knockdown increased SH-SY5Y cell viability, reduced LDH release and apoptosis, increased Bcl-2 expression, and decreased Bax and cleaved caspase-3 expression. SOX9 bound to the ASK1 promoter and promoted ASK1 transcription. SOX9 silencing suppressed ASK1, JNK, and p38 phosphorylation, while ASK1 overexpression reversed the effects of SOX9 knockdown on microglial polarization and neuronal injury. Consistently, GS-4997 blocked the pro-inflammatory and neurotoxic effects induced by SOX9 overexpression. SOX9 exacerbates AD neuroinflammation by promoting microglial M1 polarization via the ASK1/JNK signaling axis.\n\nID: 42525139\nTitle: TRIM24 Impediment suppresses VSMC modulation and attenuates neointimal hyperplasia via redox and autophagy pathways.\nAbstract: Excessive vascular smooth muscle cell (VSMC) proliferation/survival is a critical event underlying restenosis and vascular remodeling. Tripartite motif-containing 24 (TRIM24) is an oncogenic TRIM family protein with E3 ubiquitin ligase and transcriptional co-regulator functions. This study aimed to elucidate the critical role of TRIM24 in modulating VSMC functions and neointimal hyperplasia. Our in-silico network pharmacology analysis revealed that the TRIM24 inhibitor, IACS-9571, engages multiple hub genes and key pathways involved in VSMC proliferation, apoptosis, autophagy, migration, and extracellular matrix remodeling. Using Western blot and immunofluorescence analysis, we found that platelet-derived growth factor-BB (PDGF-BB) stimulation of murine primary aortic VSMCs, significantly upregulated TRIM24 expression. SiRNA-mediated knockdown of TRIM24 attenuated PDGF-BB-induced VSMC proliferation. Pharmacological inhibition of TRIM24 using IACS-9571 markedly suppressed PDGF-BB-induced VSMC proliferation, migration, and phenotypic switching. Furthermore, TRIM24 blockade enhanced autophagy in VSMCs, as evidenced by elevated LC3 and Beclin-1 protein levels, accumulation of LC3 puncta and transcriptional upregulation of autophagy-related genes, namely ATG7 and ATG4B. Also, TRIM24 inhibition reduced AKT and mTOR activation compared to PDGF-BB-stimulated VSMCs. Concurrently, TRIM24 inhibition elevated mitochondrial ROS levels, upregulated BAX expression, a pro-apoptotic gene, and significantly enhanced apoptosis, as confirmed by TUNEL and Annexin V/PI assays. In vivo, Immunofluorescence analysis demonstrated elevated TRIM24 expression within the neointimal regions. Perivascular application of the TRIM24 inhibitor prevented wire injury-induced neointimal hyperplasia. These findings identify TRIM24 as a key regulator of VSMC proliferation, migration, and phenotypic switching. Targeting TRIM24 promotes autophagy and induces apoptosis, offering a promising strategy to limit neointimal hyperplasia and pathological vascular remodeling.\n\nID: 42525132\nTitle: Immune cell-derived circulating extracellular vesicles mediate metabolic dysfunction in preclinical and clinical type 1 diabetes.\nAbstract: Type 1 diabetes (T1D) is an autoimmune disease that destroys insulin-producing \u03b2-cells. Extracellular vesicles (EVs), including exosomes, are now recognized as important mediators of intercellular communication in immune regulation and metabolic homeostasis. Yet how immune cell-derived circulating EVs contribute to metabolic dysfunction across the disease spectrum-from preclinical to clinical T1D-has not been systematically examined. We integrated four publicly available GEO datasets: GSE97123 (plasma-derived exosome miRNA profiling in long-duration T1D patients, n\u2009=\u200924), GSE92439 (T lymphocyte-derived exosome effects on pancreatic islets, n\u2009=\u20096), GSE316823 (ductal cell EV-mediated \u03b2-cell alterations, n\u2009=\u20098), and GSE160391 (cytokine-stressed islet and EV miRNA profiles, n\u2009=\u200948). Differential expression analysis was performed using Welch's t-test with Benjamini-Hochberg correction. Pathway enrichment, EV marker characterization, and cross-dataset integration were carried out to identify convergent mechanisms. In GSE97123, 292 differentially expressed miRNAs (p\u2009<\u20090.05) were identified in circulating exosomes from T1D patients compared with controls, with upregulation of pro-inflammatory mediators including miR-155-5p and miR-146a-5p. In GSE92439, T lymphocyte-derived exosomes altered 8,189 genes in pancreatic islets, with changes in insulin secretion, apoptosis, and immune recognition pathways. In GSE316823, cytokine-stimulated ductal cell EVs induced 599 differentially expressed genes in \u03b2-cells, with notable upregulation of HLA class I molecules (HLA-A, HLA-B, HLA-C) and inflammatory chemokines (CXCL9, CXCL10, CXCL11, IDO1, GBP4). In GSE160391, cytokine stress caused distinct miRNA packaging into EVs versus islet fractions, with miR-155-5p and miR-146a-5p as the only two miRNAs consistently upregulated in both compartments across sexes. Cross-dataset integration showed convergent dysregulation of antigen presentation, insulin signaling, and apoptotic pathways. Immune cell-derived EVs appear to transfer pro-inflammatory and metabolic-disruptive cargo to \u03b2-cells, supporting a pathogenic axis in T1D that has received limited attention. These findings suggest that EV-mediated communication could be a therapeutic target and that circulating EV miRNAs may serve as biomarkers for T1D progression.\n\nID: 42524981\nTitle: Time-dependent protective effects of syringic acid following testicular torsion-detorsion: an experimental rat model.\nAbstract: To investigate the protective effects of syringic acid (SA) against testicular ischemia-reperfusion (I/R) injury during different reperfusion periods in an experimental rat model. Forty-eight male Wistar albino rats were randomly assigned to six groups: control, sham, torsion/detorsion (T/D) 4 h, T/D + SA 4 h, T/D 24 h, and T/D + SA 24 h. Testicular torsion was induced by 720\u00b0 rotation of the left testis for 2 h, followed by detorsion and 4 or 24 h reperfusion. SA (10 mg/kg) was administered intraperitoneally 30 min before detorsion. Oxidative stress markers, histopathological alterations, and immunohistochemical expressions of apoptotic protease activating factor-1 (APAF-1) and inducible nitric oxide synthase were evaluated. T/D significantly decreased total antioxidant status and glutathione levels while increasing myeloperoxidase activity and APAF-1/inducible nitric oxide synthase (iNOS) expressions compared with controls (p < 0.001). SA treatment restored antioxidant capacity and attenuated inflammatory and apoptotic responses (p < 0.05). Histopathological analyses demonstrated lower Cosentino scores and higher Johnsen scores in SA-treated groups than in untreated T/D groups (p < 0.05). Malondialdehyde levels showed no significant intergroup differences. SA attenuates testicular I/R injury by reducing oxidative stress, inflammation, and apoptosis while preserving spermatogenic function and histological integrity.\n\nID: 42524858\nTitle: hUC-MSCs via \u03b2-NGF Alleviate Cognitive Impairment After Tibial Fracture Surgery by Regulating the STMN2/NMNAT2-SARM1-NF-\u03baB Signaling Pathway.\nAbstract: Perioperative neurocognitive disorders (PND) are common postoperative complications, particularly in elderly patients, marked by learning and memory deficits with limited treatment options. Human umbilical cord mesenchymal stem cells (hUC-MSCs) hold promise due to their neuroprotective and immunomodulatory effects, but their underlying mechanisms remain unclear. This study established a PND model in aged mice using tibial fracture intramedullary fixation surgery, followed by intravenous hUC-MSCs administration. Subsequently, behavioral tests, pathological examination, proteomic analysis, and other experiments were performed to verify the therapeutic effect and underlying mechanism of hUC-MSCs on PND in mice. hUC-MSCs significantly improved cognitive function in PND mice, reduced hippocampal neuronal apoptosis and neuroinflammation, and restored dendritic spine density. Mechanistically, hUC-MSCs secreted \u03b2-NGF to activate the TrkA signaling pathway, upregulate STMN2 and NMNAT2 expression, and inhibit the SARM1/NF-\u03baB pathway, thereby alleviating neuroinflammation and dendritic degeneration. Overexpression of SARM1 in the hippocampal CA1 region and \u03b2-NGF knockdown in hUC-MSCs both reversed the therapeutic effects of hUC-MSCs, confirming their critical roles. hUC-MSCs ameliorate PND pathology through the \u03b2-NGF-mediated STMN2/NMNAT2-SARM1-NF-\u03baB pathway, offering a novel cell-based therapeutic strategy for PND. Future research may focus on optimizing the secretory function of hUC-MSCs or developing small-molecule drugs targeting \u03b2-NGF to enhance therapeutic efficacy.\n\nID: 42524708\nTitle: Chemical Aspects of Controlled Cisplatin Release and Apoptosis via Nerium oleander Latex Nano-carriers in Breast Cancer Cells.\nAbstract: Plant-derived nano-carriers offer a sustainable and targeted strategy for cancer therapy. This study reports the synthesis and characterization of a latex-hybrid nano-carrier derived from Nerium oleander (LHNC), engineered for cisplatin (CDDP) delivery in breast cancer models. Physicochemical analyses confirmed stable, porous nanostructures with uniform particle size (\u223c120-150\u2009nm), moderate surface charge (+21\u2009mV), and high drug loading efficiency (\u223c85%). The system exhibited pH-responsive sustained release under acidic conditions, mimicking the tumor microenvironment. Biological evaluations demonstrated that LHNC/CDDP significantly enhanced cytotoxicity compared to free CDDP, reducing MCF-7 cell viability to \u223c38% at 24\u2009hrs. Mechanistic studies revealed elevated ROS generation, mitochondrial membrane depolarization, nuclear condensation, and caspase-mediated apoptosis. Flow cytometry confirmed pronounced G2/M arrest and increased apoptotic fractions, validating the pro-apoptotic and anti-proliferative effects of the nano-carrier. Comparative analyses across luminal (MCF-7), triple-negative (MDA-MB-231), and non-tumorigenic (MCF-10A) models highlighted selective cytotoxicity toward malignant cells while sparing normal epithelial cells. Collectively, these findings position LHNC/CDDP as a promising bioinspired nanocarrier platform that integrates natural polymer advantages with chemotherapeutic precision. While the in vitro data provide compelling proof-of-concept, translational application requires rigorous toxicological evaluation, dose optimization, and in vivo validation, particularly given the bioactive cardiac glycosides in N. oleander.\n\nID: 42524666\nTitle: Oridonin targets PRDX1 to promote apoptosis by inducing ROS-mediated ER stress and modulating autophagy.\nAbstract: Oridonin is a bioactive diterpenoid derived from the widely used traditional Chinese medicinal herb Rabdosia rubescens, exhibits broad-spectrum anti-cancer activity, with several derivatives currently in clinical trials. However, the molecular mechanism underlying its anticancer effects, especially its direct target proteins, remain to be fully elucidated. Here, we found that Oridonin promoted intracellular reactive oxygen species (ROS) accumulation, which in turn induced endoplasmic reticulum (ER) stress-mediated apoptosis. Moreover, ER stress was instrumental in inducing autophagy after Oridonin treatment, while blockade of autophagy further exacerbated Oridonin-induced cytotoxicity. Notably, using activity-based protein profiling (ABPP), we identified the anti-oxidant enzyme Peroxiredoxin 1 (PRDX1) as a key direct covalent target of Oridonin. By binding to Cysteine 173 of PRDX1, Oridonin increased intracellular ROS levels. Furthermore, PRDX1 over-expression mitigated, whereas PRDX1 knockdown potentiated, Oridonin-induced ROS accumulation, autophagy, and subsequently apoptosis. Overall, our results indicate that PRDX1 is a direct covalent binding target mediating Oridonin-induced apoptosis. These findings not only provide fresh insights into the core mechanism of Oridonin-induced cytotoxicity, but also highlight PRDX1 as a potential therapeutic target for renal cancer drug development.\n\nID: 42524664\nTitle: Therapeutic potential of hydrogen-rich water (HRW) in oxidative stress-related diseases.\nAbstract: Oxidative stress is a central mechanism in metabolic, cardiovascular, and neurodegenerative diseases, contributing to inflammation, mitochondrial dysfunction, and apoptosis. Consequently, redox-modulating therapies are increasingly explored as potential therapeutic strategies. This review evaluates the mechanistic basis, experimental evidence, and clinical applicability of hydrogen-rich water (HRW) in oxidative stress-related diseases. A structured literature search identified mechanistic, preclinical, and clinical studies investigating HRW or molecular hydrogen (H2) on oxidative stress, inflammation, mitochondrial regulation, and disease-related outcomes. Due to substantial methodological heterogeneity, findings were synthesized qualitatively. HRW has been proposed to selectively neutralize highly reactive species such as hydroxyl radicals (\u2022OH) and peroxynitrite (ONOO-) while preserving physiological reactive oxygen species signalling. Mechanistic studies demonstrate activation of nuclear factor erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE) pathways, suppression of nuclear factor kappa B (NF-\u03baB) and mitogen-activated protein kinase (MAPK) inflammatory cascades, modulation of JAK/STAT signalling, preservation of mitochondrial bioenergetics, and enhancement of autophagic regulation. Preclinical and clinical studies report improvements in glycaemic control, endothelial function, cardiometabolic health, neuroprotection, exercise performance, and treatment-related fatigue. Despite an excellent safety profile, standardization of HRW preparation and large multicentre randomized controlled trials (RCTs) remain necessary to establish clinical efficacy and translational potential.\n\nID: 42524636\nTitle: The mechanism of polycystic ovarian syndrome induced by circadian rhythm disturbance and the therapeutic effect of melatonin.\nAbstract: Environmental factors are crucial causes of polycystic ovary syndrome (PCOS). There is growing evidence of an association between circadian rhythm disturbance and PCOS, but the underlying molecular mechanisms This study aimed to explore the molecular mechanism of PCOS induced by circadian rhythm disturbance and evaluate the therapeutic potential of melatonin. A rat model of circadian rhythm disturbance was established via 24-h continuous light exposure. Rats were randomly divided into the Control group (normal circadian rhythm), Model group (continuous light exposure), and Model\u2005+\u2005Melatonin treatment group (continuous light exposure\u2005+\u2005melatonin). Reproductive endocrine indicators, ovarian histomorphology, and ovarian granulosa cell (GC) function were assessed. Additionally, circadian rhythms of serum hormones, autophagy-related markers (LC3), and hypothalamic clock genes were detected at six zeitgeber time (ZT) points. Autophagy and apoptosis levels in GCs, as well as the activation of MAPK and PI3K/Akt/mTOR pathways, were also detected. Continuous light exposure induced PCOS-like phenotypes in rats, characterized by disrupted estrous cycles, cystic ovarian changes, and loss of circadian rhythms in serum hormones, autophagy marker LC3, and hypothalamic clock genes. Moreover, continuous light exposure reduced GC viability, increased GC autophagy and apoptosis, activated the MAPK pathway, and inhibited the PI3K/Akt/mTOR pathway in GCs. Melatonin treatment significantly ameliorated these PCOS-like phenotypes. Our study showed circadian rhythm disturbance induced PCOS via MAPKs and PI3K/Akt/mTOR signaling pathways and increased autophagy level in rat ovarian GCs. Melatonin had a therapeutic effect on PCOS by reversing these signaling pathway abnormalities and reducing autophagy and apoptosis levels in GCs.\n\nID: 42524633\nTitle: Molecular and developmental consequences of heat stress on the bovine oocyte and embryo competence.\nAbstract: Seasonal heat stress (HS) is a pervasive environmental challenge with profound consequences for female reproductive physiology, affecting ovarian function, oocyte maturation, and early embryonic development. At the ovarian level, HS disrupts follicular growth, impairs steroidogenesis, and compromises granulosa cell function, thereby creating a suboptimal microenvironment that reduces oocyte competence. In oocytes, HS induces oxidative stress, mitochondrial dysfunction, endoplasmic reticulum (ER) stress, spindle abnormalities, chromosomal missegregation, and persistent epigenetic alterations. These disruptions extend into early embryonic development, where redox imbalance, apoptosis, ER stress, and altered lineage allocation reduce cleavage and blastocyst formation, compromise trophectoderm and inner cell mass integrity, and impair implantation potential. Maternal heat exposure further exacerbates embryonic vulnerability by altering the oviductal and uterine environment, reducing embryotrophic factors and antioxidant defenses, and ultimately influencing offspring phenotype and fertility, potentially across generations. Accordingly, this review aims to synthesize current knowledge on the physiological and molecular impacts of heat stress on ovarian function, oocyte maturation, and early embryonic development. To this end, we consider studies conducted under both in vivo and in vitro conditions, highlighting shared and distinct mechanisms of thermal stress at the organ and cellular levels to identify potential targets for intervention.\n\nID: 42524632\nTitle: The Marine Triterpene Stellettin B Triggers Mitochondrial-to-Nuclear Translocation of AIF/EndoG and Reverses Epithelial-Mesenchymal Transition to Inhibit Oral Cancer Progression.\nAbstract: Oral squamous cell carcinoma (OSCC) is associated with aggressive clinical behavior and poor outcomes. In this study, we investigated the anticancer efficacy and underlying mechanisms of Stellettin B, an isomalabaricane triterpene isolated from the marine sponge Jaspis stellifera, in OSCC cells. Our results demonstrate that Stellettin B significantly inhibited the proliferation of HSC-3 and OC-2 cells while sparing normal oral keratinocytes. Mechanistically, Stellettin B triggers a predominantly caspase-independent apoptotic program, evidenced by the pronounced mitochondrial-to-nuclear translocation of apoptosis-inducing factor (AIF) and endonuclease G (EndoG) following DNA damage, whereas classical caspase activation functions as a dispensable, secondary event. Furthermore, Stellettin B suppressed migration and invasion by reversing epithelial-mesenchymal transition (EMT), characterized by E-cadherin upregulation and downregulation of Vimentin, Snail, Slug, and \u03b2-catenin. Transcriptomic profiling further revealed significant suppression of mTORC1 signaling and EDIL3 expression. In conclusion, these findings demonstrate that Stellettin B exerts multimodal antitumor activity in OSCC and highlight its therapeutic potential as a marine-derived anticancer agent.\n\nID: 42524598\nTitle: Cleaning, Chasing and Calming: Promising Paradigms of Senotherapy in Aging-Related Diseases.\nAbstract: With the acceleration of global population aging, the pathological accumulation of senescent cells (SnCs) has been confirmed as the core biological mechanism driving multiple aging-related diseases. This article aims to systematically review the formation mechanism of SnCs and their pathological roles in various tissue lesions, and to specifically evaluate the progress of three cutting-edge intervention strategies (Senolytics, Immuno-senolytics and Senomorphics). Senolytics selectively induces programmed apoptosis in SnCs by antagonizing senescent cell anti-apoptotic pathways. Immuno-senolytics include vaccines, engineered cell therapy and specific antibodies, which utilize the immune surveillance mechanism to achieve efficient elimination of SnCs. Senomorphics precisely reshape the SASP profile by targeting signaling axis or interfering with epigenetic modifications. Although the strategies have demonstrated remarkable potential for reversing pathology, their clinical translation still faces challenges such as the heterogeneity of SnCs, the lack of specific markers, and potential off-target toxicity. Future research should focus on multidisciplinary collaboration, aiming to optimize spatiotemporal targeted delivery systems and combination drug regimens to build a safer and more precise anti-senescence treatment system.\n\nID: 42524594\nTitle: Targeting Ash1L-STING Axis Restores NK Cell Function and Ameliorates Immune-Mediated Bone Marrow Failure Diseases.\nAbstract: Aplastic anemia (AA) is an immune-mediated bone marrow failure (BMF) syndrome characterized by pancytopenia and bone marrow hypocellularity. While natural killer (NK) cell dysfunction contributes to AA pathogenesis, the epigenetic mechanisms linking genomic instability to inflammatory hyperactivation remain poorly defined. Here, we identify the histone methyltransferase Ash1L as a critical regulator of NK cell homeostasis in AA. Ash1L expression was markedly reduced in NK cells from AA patients and correlated with disease severity and elevated proinflammatory cytokines. Ash1L knockdown reduced NK cell viability, induced apoptosis and G1 cell-cycle arrest, and enhanced secretion of IL-6 and TNF-\u03b1. Mechanistically, Ash1L deficiency resulted in reduced H3K4 and H3K36 methylation, impairing activation of the ATM-CHK2-p53 signaling pathway, resulting in persistent \u03b3H2AX foci accumulation and aberrant activation of the cGAS-STING signaling pathway. Treatment with the natural compound Andrographolide (Andro) suppressed STING signaling, enhanced DNA damage repair efficiency, and partially restored NK cell function. In an immune-mediated BMF mouse model, Andro attenuated inflammatory responses, restored Ash1L expression in NK cells, inhibited STING pathway activation, and improved hematopoiesis. Collectively, these findings suggest that Ash1L acts as an epigenetic safeguard of genomic stability and inflammatory restraint in NK cells and highlight Andro as a potential therapeutic agent for AA and related immune-mediated BMF disorders.\n\nID: 42524582\nTitle: Licoricidin triggers reactive oxygen species-mediated PANoptosis in human hepatocellular carcinoma cells.\nAbstract: Licoricidin (LCD), a natural isoflavonoid compound extracted from Glycyrrhiza species, has been extensively demonstrated to possess diverse biological activities, including anti-inflammatory and potent anti-cancer effects. However, the precise mechanism underlying LCD action against hepatocellular carcinoma (HCC) remains unclear, particularly regarding its regulation of cell death. In this study, we comprehensively explored the effects of LCD on HCC cells in vitro and investigated its role and mechanism of action in the induction of PANoptosis. Our results reveal that LCD exhibited potent anti-HCC activities by decreasing cell viability and significantly inhibiting clonogenic survival in HCC cell lines. Our results demonstrate that LCD triggered a substantial accumulation of reactive oxygen species and induced depolarization of the mitochondrial membrane, leading to profound mitochondrial dysfunction. We further confirmed that LCD activated a comprehensive PANoptosis program by synchronously upregulating the expression of apoptotic proteins (Bax, c-CASP3, and c-PARP1), pyroptotic proteins (c-CASP 1 and c-GSDMD), and the phosphorylation of necroptotic executioners (p-MLKL and p-RIPK1). Treatment with the ROS inhibitor (NAC), apoptosis inhibitor (ZVAD), or necroptosis inhibitor (Nec-1) significantly reduced the expression of PANoptosis-related proteins in LCD-treated cells. Furthermore, molecular docking simulations and cellular thermal shift assay (CETSA) assay confirmed the direct and stable binding of LCD to PANoptosis-related proteins. In summary, we show for the first time that LCD exerts favorable anti-HCC activities via the induction of PANoptosis through a ROS-dependent mechanism and potntial direct modulation of core executive proteins. This multi-target action suggests that LCD could be a novel candidate for the management of hepatocellular carcinoma.\n\nID: 42524343\nTitle: tsRNA's Biological Function and its Potential Application in Disease Diagnosis and Prognosis.\nAbstract: Under physiological conditions, tsRNAs regulate mRNA transcription, reverse transcription, and protein translation to mediate cell apoptosis, cell cycle, and epigenetic regulation. Pathogenic tsRNAs are disease-specific or disease-related tsRNAs that are highly express in various diseases and may serve as diagnostic or potential diagnostic biomarkers. Specifically expressed tsRNAs in tumors were screened and obtained from the tumors. Although the mechanisms by which these oncogenic tsRNAs contribute to tumor development remain unclear, they have been shown to be applicable to tumor diagnosis and therapeutic prognosis. This article briefly summarizes pathogenic tsRNAs involved in various diseases and their biological functions. Oncogenic tsRNAs in tumors and their clinical applications have been elaborated upon. The molecular mechanisms of pathological tsRNAs in both general diseases and tumors need to be further investigated in future.\n\nID: 42524323\nTitle: Rab GTPases drive ligand-independent NOTCH1 activation via altered endocytic trafficking in chronic lymphocytic leukemia.\nAbstract: Clinically relevant NOTCH1 activation is frequently observed in chronic lymphocytic leukemia (CLL), even in the absence of gene mutations, raising questions about the underlying mechanisms. In CLL cells, NOTCH1 activation may occur through mutation-independent mechanisms involving ligand interaction or cell-intrinsic, ligand-independent pathways that are not yet fully elucidated. To explore ligand-independent activation, we examined the involvement of NOTCH1 endocytic trafficking in generating the active intracellular domain (N1-ICD) in CLL cells. Using proximity ligation assay, we demonstrated that the NOTCH1 extracellular domain (N1-ECD), transmembrane subunit (N1-TM), and N1-ICD colocalize with Rab5 and Rab7, indicating NOTCH1 internalization and cleavage within endosomal compartments. Experiments with the endocytosis inhibitor Pitstop-2 demonstrated that NOTCH1 internalization is essential for N1-ICD generation. We provided evidence that N1-ICD generation occurs in Rab5 and Rab7 endosomal membranes. Treatment with chloroquine reduced N1-ICD, due to impaired endosomal acidification affecting enzymatic activity. Presenilin-1, the catalytic subunit of the \u03b3-secretase complex responsible for N1-ICD generation, was found in early endosome compartments and colocalized with Rab5, Rab7, N1-TM, and N1-ICD. CLL cells expressing N1-ICD showed higher Rab5, Rab7, and presenilin-1 levels, increased Rab5 membrane association, and presenilin-1 activity versus N1-ICD-negative cells which showed increased lysosomal targeting. Silencing Rab5 or Rab7 by siRNA, or inhibiting Rab prenylation with psoromic acid, led to reduced N1-ICD levels and increased apoptosis in CLL cells. Interestingly, NOTCH1-mutated cases showed similar NOTCH1 trafficking. These findings identify for the first time a Rab-dependent endocytic trafficking as a key regulator of NOTCH1 activation and a potential therapeutic target in CLL.\n\nID: 42524317\nTitle: Inhibition of UBE2N enhances TRAIL-mediated apoptosis through upregulation of DR5 in cancer cells.\nAbstract: Tumor necrosis factor-related apoptosis-induced ligand (TRAIL) selectively induces apoptosis in cancer cells. However, many cancer cells are resistant to TRAIL because of downregulation of death receptors (DRs) and overexpression of anti-apoptotic proteins. Ubiquitin-conjugating enzyme E2N (UBE2N), also known as Ubc13, plays a central role in ubiquitin-mediated cellular activities. In this study, we aimed to explore the sensitization effect of UBE2N inhibition in TRAIL-mediated apoptosis in cancer cells. NSC697923 (a potent inhibitor of UBE2N) alone and TRAIL alone did not induce apoptosis in renal carcinoma Caki cells. However, combined treatment with NSC697923 and TRAIL significantly enhanced apoptotic cell death in cancer cells, but not in normal cells. Mechanistically, NSC697923 induced upregulation of DR5 mRNA and protein levels through CHOP-mediated DR5 transcriptional activation and ubiquitin-mediated DR5 stabilization. NSC697923-mediated DR5 mRNA upregulation was regulated by upregulation of CHOP expression, a key transcriptional factor of DR5. CHOP siRNA treatment inhibited NSC697923-mediated DR5 protein expression. Moreover, NSC697923 generated ROS, and pretreatment with ROS scavengers inhibited DR5 upregulation and NSC697923 plus TRAIL-mediated cell death. These findings suggest that UBE2N inhibitor enhances TRAIL-induced apoptosis by DR5 upregulation and UBE2N inhibition may serve as a potential strategy to overcome TRAIL resistance in cancer therapy.\n\nID: 42524252\nTitle: Integrating network pharmacology, molecular docking, and experimental validation to investigate the therapeutic effects and potential mechanisms of lycopene against pancreatic ductal adenocarcinoma.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) is an extremely aggressive tumor of the digestive system with a very low five-year survival rate. The limited efficacy and significant toxicity of existing chemotherapy regimens make the development of novel natural therapeutic agents an urgent priority. Lycopene is a natural carotenoid that has been shown to inhibit multiple cancers. However, research specifically targeting PDAC remains relatively scarce. This study first employed bibliometric analysis to examine the research landscape and emerging trends in lycopene-related cancer research from 2016 to 2026. Subsequently, network pharmacology methods are applied to screen potential lycopene targets and PDAC-related targets from databases such as CTD, ChEMBL and HERB. Following the identification of overlapping targets, drug-target and protein-protein interaction (PPI) networks are constructed, as well as a disease network. The mechanisms were explored using Gene Ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Molecular docking was used to predict the potential interactions between lycopene and representative hub targets, and molecular dynamics simulations were performed for selected high-ranking docking complexes to provide supportive information on complex-level conformational stability. In vitro experiments were then conducted to evaluate the predicted anti-PDAC effects and to perform focused validation of apoptosis-related proteins and the PI3K/Akt/P53 signaling axis. Publications on lycopene research in the field of cancer have shown a sustained upward trend. The focus of this research has gradually shifted from areas such as oxidative stress and antioxidant effects towards anti-cancer mechanisms. A total of 132 overlapping targets for lycopene's anti-PDAC activity were screened, leading to the identification of 10 core targets, including BCL2, AKT1, and TP53. GO enrichment analysis revealed that these targets are involved in biological processes such as the response to oxidative stress and cellular senescence. Meanwhile, KEGG enrichment analysis identified the PI3K-Akt signaling pathway as a key pathway. Molecular docking results showed that the binding energies of lycopene with core targets such as TP53 and BCL2 were below -4.5\u202fkcal/mol. Molecular dynamics simulations provided supportive evidence for the conformational stability of representative lycopene-target complexes. In vitro experiments showed that lycopene inhibited the proliferation and migration of PDAC cells and promoted apoptosis-associated cell death, accompanied by decreased p-PI3K and p-AKT expression and increased P53 expression. This study systematically combined bibliometrics, network pharmacology, molecular docking, representative molecular dynamics simulations, and focused experimental validation to explore the potential anti-PDAC activity of lycopene. The inflammation-related hub targets identified by network analysis provide additional hypotheses for future experimental investigation. These findings provide preliminary mechanistic evidence for further preclinical investigation of lycopene in PDAC, but its translational application will require optimized formulations, pharmacokinetic validation, and in vivo efficacy studies to overcome its limited bioavailability.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

However, the precise mechanism underlying LCD action against hepatocellular carcinoma (HCC) remains unclear, particularly regarding its regulation of cell death. In this study, we comprehensively explored the effects of LCD on HCC cells in vitro and investigated its role and mechanism of action in the induction of PANoptosis. Our results reveal that LCD exhibited potent anti-HCC activities by decreasing cell viability and significantly inhibiting clonogenic survival in HCC cell lines. Our results demonstrate that LCD triggered a substantial accumulation of reactive oxygen species and induced depolarization of the mitochondrial membrane, leading to profound mitochondrial dysfunction. We further confirmed that LCD activated a comprehensive PANoptosis program by synchronously upregulating the expression of apoptotic proteins (Bax, c-CASP3, and c-PARP1), pyroptotic proteins (c-CASP 1 and c-GSDMD), and the phosphorylation of necroptotic executioners (p-MLKL and p-RIPK1). Treatment with the ROS inhibitor (NAC), apoptosis inhibitor (ZVAD), or necroptosis inhibitor (Nec-1) significantly reduced the expression of PANoptosis-related proteins in LCD-treated cells. Furthermore, molecular docking simulations and cellular thermal shift assay (CETSA) assay confirmed the direct and stable binding of LCD to PANoptosis-related proteins. In summary, we show for the first time that LCD exerts favorable anti-HCC activities via the induction of PANoptosis through a ROS-dependent mechanism and potntial direct modulation of core executive proteins. This multi-target action suggests that LCD could be a novel candidate for the management of hepatocellular carcinoma.\n  --- END ACTUAL ABSTRACT FOR 42524582 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Ferroptosis is an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation.\" (Source: 42526049)\n- \"Emerging evidence indicates that susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets.\" (Source: 42526049)\n- \"Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms.\" (Source: 42524084)\n- \"We found that iron accumulates with aging, but surprisingly decreases with AIE.\" (Source: 42526057)\n- \"Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production.\" (Source: 42526057)\n- \"Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis\" (Source: 42524611)\n- \"Collectively, these findings suggest that SYNCRIP is a key regulator of GBM progression by maintaining metabolic homeostasis and ferroptosis resistance, highlighting SYNCRIP as a potential therapeutic target in GBM.\" (Source: 42524498)\n- \"Methionine restriction elevated LCL lipid reactive oxygen species and triggered ferroptosis.\" (Source: 42523280)\n- \"These convergent mechanisms position ZDHHC-mediated S-palmitoylation as a context-dependent regulator of tumor progression, therapy response, ferroptosis sensitivity, and immune phenotype.\" (Source: 42524518)\n- \"Mechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment.\" (Source: 42525168)\n- \"Mechanistically, H3K18la was enriched in the promoter region of ACSL4 to facilitate its transcriptional activation, and knockdown of ACSL4 markedly reversed OGD/R-triggered cardiomyocyte ferroptosis.\" (Source: 42522960)\n- \"Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time.\" (Source: 42519304)\n- \"Recent bursts (2024\u20112025) highlight \"pyroptosis\" and \"ferroptosis\" as emerging frontiers.\" (Source: 42517156)\n- \"Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways\" (Source: 42521052)\n- \"RRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis.\" (Source: 42520529)\n- \"KRAS G12D mutations in lung epithelium drive proliferation of resident, embryonically-derived alveolar macrophages, which then promote tumor cell proliferation and protection from ferroptosis, leading to tumor progression.\" (Source: 42523303)\n- \"This review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways.\" (Source: 42517085)\n- \"Intriguingly, the addition of a ferroptosis inhibitor, liproxstatin-1, to the combination therapy significantly abrogated the in vivo synergism between SBRT and KRAS inhibition, suggesting that treatment-induced ferroptosis at least partially drives the synergistic efficacy of this combination strategy.\" (Source: 42523398)\n- \"Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity.\" (Source: 42517079)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Its physiological and pathological roles span multiple medical domains, including oncology, neurodegeneration, and cardiovascular disease. Modulation of ferroptotic pathways, through iron homeostasis, antioxidant defense (e.g., GPX4/System Xc- axis), and lipid metabolism, offers a significant therapeutic frontier, particularly in overcoming treatment resistance.\n\n### [INTRODUCTION & JUSTIFICATION]\nFerroptosis is an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation. Emerging evidence indicates that susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets. Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **The Driver-Amplifier Concept:** In drug-induced cardiotoxicity (specifically Doxorubicin), ferroptosis is being re-evaluated not merely as an initiator, but potentially as a downstream amplifier of cardiac damage.\n*   **Cross-Organelle Coordination:** Sensitivity is not just cytoplasmic; mitochondria, lysosomes, and lipid droplets act as integrated rheostats for cell death execution.\n*   **Transcriptional Regulation of Lipid Metabolism:** Histone acylation (H3K18la) directly modulates ACSL4 to trigger ferroptosis in myocardial ischemia-reperfusion scenarios.\n*   **Viral Manipulation:** EBV latency III programs are found to redirect methionine metabolism toward redox defense, specifically inducing transsulfuration to sustain cysteine and glutathione pools, creating a targetable ferroptotic vulnerability.\n*   **Radiation Synergy:** Ferroptosis induction is a key driver of the synergistic efficacy observed in combined radiotherapy and KRAS inhibition in pancreatic cancer models.\n*   **Immune/Ferroptosis Crosstalk:** Ferroptosis-related transcriptional activities are dynamically activated alongside pyroptosis and necroptosis after spinal cord injury, suggesting a collaborative lytic cell death program.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation. In this review, we summarize the molecular mechanisms by which microglial ferroptosis mediates neuroinflammatory responses, with a focus on iron homeostasis disruption, lipid peroxidation and ROS amplification, collapse of the GPX4-dependent antioxidant defense, mitochondrial ROS generation, and inflammasome activation. We further classify related CNS diseases into three categories according to disease course and pathological features: chronic neurodegenerative and demyelinating diseases, acute CNS injuries, and neuropsychiatric or systemic inflammation-related brain dysfunction. Within this framework, we compare the pathological significance of microglial ferroptosis across different disease contexts. We also discuss potential therapeutic strategies targeting iron homeostasis, lipid peroxidation, antioxidant defenses, inflammatory amplification networks, and microglia-specific delivery systems. Finally, we address current challenges in the field, including insufficient cell-type specificity, inconsistent detection criteria, disease-stage heterogeneity, and barriers to clinical translation. This review provides an integrated perspective on the mechanisms by which microglial ferroptosis drives neuroinflammation and highlights its potential relevance for precision intervention in CNS diseases."

This study aimed to investigate the role of ferroptosis in CA-induced spinal cord injury and to evaluate the neuroprotective effects of edaravone. Asphyxial CA was induced in rats for 5\u202fmin, followed by resuscitation. Edaravone was administered immediately after the return of spontaneous circulation (ROSC). At 24\u202fh post-ROSC, The CA group exhibited significant hindlimb motor deficits and reduced survival rates. Histological analysis revealed selective injury of choline acetyltransferase (ChAT)-positive motor neurons in the lumbar spinal cord, accompanied by mitochondrial shrinkage and membrane rupture, which are characteristic of ferroptosis. Immunofluorescence demonstrated a selective upregulation of the pro-ferroptotic enzyme acyl-CoA synthetase long-chain family member 4 (ACSL4) specifically in ChAT-positive motor neurons, whereas glutathione peroxidase 4 (GPX4) expression remained relatively preserved. Edaravone treatment significantly improved neurological outcomes and survival, attenuated lipid peroxidation (evidenced by decreased malondialdehyde and preserved glutathione levels), and effectively suppressed ACSL4 upregulation in the motor neurons. Furthermore, edaravone mitigated neuroinflammation by reducing astrogliosis and microglial activation. These findings provide the first evidence that ACSL4-mediated ferroptosis is a key driver of acute spinal motor neuron injury following CA. Edaravone exerts potent neuroprotection by targeting this pathway, suggesting its therapeutic potential for ameliorating spinal cord injury in patients with CA."

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma."

PANoptosis is a newly identified cell death mode that synergistically initiates pyroptosis, apoptosis and necroptosis via activation of PANoptosome. It is closely associated with oxidative stress, neuroinflammation, and secondary injury following TBI and SCI, yet the key pathogenic factors and mechanisms underlying PANoptosis remain incompletely elucidated. Mitochondria, as a central organelle for energy synthesis and oxidative stress, its health and homeostasis are the cornerstone of cell survival and biological function. Emerging evidence suggests that the loss of mitochondrial homeostasis plays a fundamental role in the activation and execution of PANoptosis across various cell types. Here, we review the detailed manifestations of mitochondrial homeostasis imbalance in TBI and SCI, such as impaired biogenesis, abnormal dynamics, mitophagy dysfunction, and mitochondria-derived vesicles. Meanwhile, we systematically analyze the characteristics and pathological effects of PANoptosis cascade following TBI and SCI, with a focus on the regulatory patterns, mechanisms, and potential targets of injured mitochondria driving PANoptosis. In addition, we discuss the advancements and future perspectives of mitochondria-based strategies for modulating PANoptosis in TBI and SCI. Taken together, despite considerable challenges in governing post-traumatic mitochondria homeostasis, its multiple targeting of the upstream PANoptosome and downstream cell death signaling offers a promising approach to improve the outcome of CNS trauma."

This study aims to investigate the regulatory role of anti-HMGB1 antibody in the depressive-like behaviour of D-SCI rats and to explore its underlying mechanisms. A depression model was established in rats 5\u2009weeks after SCI. The expression of HMGB1 and ferroptosis markers (MDA, GSH and iron ion deposition) in the hippocampus were examined in both the sham group and the D-SCI group. Subsequently, D-SCI rats were treated with an anti-HMGB1 antibody, and the depression-like behaviours of each group were assessed using open field and sucrose preference tests. Ferroptosis levels in the hippocampus, as well as the expression of ferroptosis-related proteins (ACSL4, SLC7A11 and GPX4), were also investigated. The co-localization of HMGB1 and NeuN in the rat hippocampus was detected by immunofluorescence double staining. Furthermore, at the cellular level, the effect of the anti-HMGB1 antibody on Erastin-induced ferroptosis in rat hippocampal neurons was analysed. The results indicated that compared to the sham group, the levels of HMGB1 and ferroptosis in the hippocampus of rats in the D-SCI group were significantly elevated. Administering anti-HMGB1 antibody to D-SCI rats could significantly augment their activity distance, movement speed and sucrose preference rate, while also suppressing the ferroptosis level and the expression of ferroptosis-related proteins in the hippocampus. Moreover, HMGB1 and NeuN were co-expressed in the rat hippocampus. The results from primary rat hippocampal neurons indicated that anti-HMGB1 antibody could inhibit erastin-induced ferroptosis in rat hippocampal neurons. Taken together, anti-HMGB1 antibody therapy can ameliorate depressive behaviour in D-SCI rats; the possible mechanism may involve the inhibition of ferroptosis in hippocampal neurons."

We investigated the role of sphingosine-1-phosphate receptor 2 (S1P2 receptor) in contusive spinal cord injury and evaluated the therapeutic effects of an S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) in a rat model of SCI. The SCI model was established using a 10\u2009g weight dropped onto the T10 vertebrae in female rats. After functional testing, spinal cords were harvested for biochemical and histopathological assays at different time points. Nissl and Prussian blue staining were used to analyse neuronal death. Neuronal ferroptosis in spinal cords was examined using transmission electron microscopy, and lipid peroxidation in the cultured neurones was analysed. After SCI, S1P (Sphingosine 1-phosphate) was released from crushed spinal cords and subsequently activated the neuronal S1P2 receptor to increase lipid peroxidation, which injured neurones via inducing neuronal ferroptosis through the P-ERK/ERK/ACSL4 pathway, resulting in limb paralysis. S1P2 receptor inhibition significantly blocked S1P2 receptor activation and attenuated neuronal ferroptosis. Thus, S1P2 receptor was a therapeutic target for the treatment of SCI. Systemic administration of the S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) effectively promoted locomotor function recovery by attenuating neuronal ferroptosis in rat spinal cords. S118 impeded neuronal ferroptosis by inhibiting lipid peroxidation. Contusive SCI is characterised by neuronal loss due to S1P2 receptor activation in spinal neurones. S1P2 receptor activation increases lipid peroxidation, which induces neuronal ferroptosis. S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) improves locomotor functional recovery by preserving the spinal cord structure after SCI."

Primary microglia cells were extracted from neonatal 1-2 days C57BL/6 mice and divided into control group, Yoda1 (Piezo1 agonist) group, and Yoda1+GsMTx4 (Piezo1 inhibitor) group. Live/dead cell staining, reactive oxygen species (ROS) fluorescence staining, 5, 5', 6, 6'-tetrachloro-1, 1', 3, 3'-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) mitochondrial membrane potential detection, and transmission electron microscopy were utilized to assess microglial ferroptosis and mitochondrial functional characteristics. SPF female C57BL/6 mice aged 6 to 8 weeks were used to detect the expression of Piezo1 at different time points after SCI by Western blot, and the two time points with no significant change and the most significant change in Piezo1 expression after SCI were selected for subsequent experiments. T 8, T 9 SCI models were established by modified Allen's method, and were divided into sham operation group, injury group, and injury+shPiezo1 group (Piezo1-targeted interfering virus AAV-shPiezo1 was injected in situ to knock down the expression of Piezo1 14 days before modeling). Colocalization of Piezo1 with microglial markers purinergic receptor P2Y12 (P2ry12), and the expressions of glutathione peroxidase 4 (GPX4) and acyl coenzyme A synthetase long chain member 4 (ACSL4) were observed by immunofluorescence staining. Basso Mouse Scale (BMS) score was used to assess hindlimb motor function in mice. The level of ROS was detected by dihydroethidium (DHE) staining; the content of malondialdehyde (MDA) was detected by MDA kit; the levels of tumor necrosis factor \u03b1 (TNF-\u03b1) and interleukin 10 (IL-10) were detected by ELISA assay; the pathological morphology of spinal cord was observed by HE staining. In vitro experiments showed that compared with the control group, the Yoda1 group had typical ultrastructural changes of ferroptosis, such as increased microglial cell death, enhanced ROS fluorescence, mitochondrial membrane potential depolarization, mitochondrial shrinkage and mitochondrial cristae breakage (all P<0.05), while the GsMTx4 group could partially reverse the above effects ( P<0.05). In vivo experiments demonstrated that the expression of Piezo1 in spinal cord tissue was up-regulated sequentially after SCI, and reached the peak on the 7th day after SCI ( P<0.05), and it was mainly localized in P2ry12-positive microglia. Compared with the injury group, in the injury+shPiezo1 group, the expression of ferroptosis core protein GPX4 in microglia was increased, the expression of ACSL4 was decreased, the levels of ROS and MDA in spinal cord tissue were decreased ( P<0.05), the level of pro-inflammatory factor TNF-\u03b1 was decreased, and the level of anti-inflammatory factor IL-10 was increased ( P<0.05). In addition, the BMS score was significantly higher than that of the injury group ( P<0.05) from the 14th day after operation, and the spinal cord tissue structure was relatively well preserved, and the cavity area was reduced. SCI activates the Piezo1 channel in microglia, triggering mitochondrial dysfunction and mediating cellular ferroptosis, thereby aggravating secondary neuroinflammation. Targeted inhibition of Piezo1 effectively blocks the ferroptosis process, ameliorates the immune microenvironment, and promotes tissue repair and locomotor functional recovery after SCI. \u63a2\u7a76\u673a\u68b0\u654f\u611f\u6027\u79bb\u5b50\u901a\u9053Piezo1\u5728\u810a\u9ad3\u635f\u4f24\uff08spinal cord injury\uff0cSCI\uff09\u540e\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u4e2d\u7684\u4f5c\u7528\u673a\u5236\uff0c\u5e76\u8bc4\u4f30\u6291\u5236Piezo1\u5bf9\u6539\u5584\u635f\u4f24\u5fae\u73af\u5883\u53ca\u4fc3\u8fdb\u795e\u7ecf\u529f\u80fd\u6062\u590d\u7684\u5f71\u54cd\u3002. \u63d0\u53d6\u65b0\u751f1\uff5e2 d C57BL/6\u5c0f\u9f20\u539f\u4ee3\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001Yoda1\uff08Piezo1\u6fc0\u52a8\u5242\uff09\u7ec4\u53caYoda1+GsMTx4\uff08Piezo1\u6291\u5236\u5242\uff09\u7ec4\u3002\u5229\u7528\u6d3b\u6b7b\u7ec6\u80de\u67d3\u8272\u3001\u6d3b\u6027\u6c27\uff08reactive oxygen species\uff0cROS\uff09\u8367\u5149\u67d3\u8272\u30015\uff0c5\u2019\uff0c6\uff0c6\u2019-\u56db\u6c2f-1\uff0c1\u2019\uff0c3\uff0c3\u2019-\u56db\u4e59\u57fa\u82ef\u5e76\u54aa\u5511\u78b3\u82b1\u9752\u7898\u5316\u7269\uff085\uff0c5\u2019\uff0c6\uff0c6\u2019-tetrachloro-1\uff0c1\u2019\uff0c3\uff0c3\u2019-tetraethylbenzimidazolylcarbocyanine iodide\uff0cJC-1\uff09\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u68c0\u6d4b\u53ca\u900f\u5c04\u7535\u955c\u89c2\u5bdf\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u53ca\u7ebf\u7c92\u4f53\u529f\u80fd\u7279\u5f81\u3002\u53d66\uff5e8\u5468\u9f84SPF\u7ea7\u96cc\u6027C57BL/6\u5c0f\u9f20\uff0c\u91c7\u7528Western blot\u68c0\u6d4bPiezo1\u5728SCI\u540e\u4e0d\u540c\u65f6\u95f4\u70b9\u7684\u8868\u8fbe\u89c4\u5f8b\uff0c\u9009\u53d6\u635f\u4f24\u540ePiezo1\u8868\u8fbe\u672a\u89c1\u660e\u663e\u6539\u53d8\u53ca\u53d8\u5316\u6700\u663e\u8457\u76842\u4e2a\u65f6\u95f4\u70b9\u8fdb\u884c\u540e\u7eed\u5b9e\u9a8c\u3002\u91c7\u7528\u6539\u826fAllen\u6cd5\u5236\u5907T 8\u3001T 9 SCI\u6a21\u578b\uff1b\u5b9e\u9a8c\u5206\u4e3a\u5047\u624b\u672f\u7ec4\u3001\u635f\u4f24\u7ec4\u548c\u635f\u4f24+shPiezo1\u7ec4\uff08\u9020\u6a21\u524d14 d\u539f\u4f4d\u6ce8\u5c04\u9776\u5411Piezo1\u7684\u5e72\u6270\u75c5\u6bd2AAV-shPiezo1\u4ee5\u6572\u4f4ePiezo1\u8868\u8fbe\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u89c2\u5bdfPiezo1\u4e0e\u5c0f\u80f6\u8d28\u7ec6\u80de\u6807\u5fd7\u7269\u560c\u5464\u80fd\u53d7\u4f53P2Y12\uff08purinergic receptor P2Y12\uff0cP2ry12\uff09\u7684\u5171\u5b9a\u4f4d\u53ca\u8c37\u80f1\u7518\u80bd\u8fc7\u6c27\u5316\u7269\u91764\uff08glutathione peroxidase 4\uff0cGPX4\uff09\u3001\u9170\u57fa\u8f85\u9176A\u5408\u6210\u9176\u957f\u94fe\u5bb6\u65cf\u6210\u54584\uff08acyl coenzyme A synthetase long chain member 4\uff0cACSL4\uff09\u7684\u8868\u8fbe\uff1bBasso Mouse Scale\uff08BMS\uff09\u8bc4\u5206\u8bc4\u4f30\u5c0f\u9f20\u540e\u80a2\u8fd0\u52a8\u529f\u80fd\uff1b\u4e8c\u6c22\u4e59\u952d\uff08dihydroethidium\uff0cDHE\uff09\u67d3\u8272\u68c0\u6d4b\u7ec4\u7ec7ROS\u6c34\u5e73\uff1b\u4e19\u4e8c\u919b\uff08malondialdehyde\uff0cMDA\uff09\u8bd5\u5242\u76d2\u68c0\u6d4bMDA\u542b\u91cf\uff1bELISA\u68c0\u6d4b\u708e\u75c7\u56e0\u5b50TNF-\u03b1\u3001IL-10\u6c34\u5e73\uff1bHE\u67d3\u8272\u89c2\u5bdf\u810a\u9ad3\u7ec4\u7ec7\u75c5\u7406\u5f62\u6001\u3002. \u4f53\u5916\u5b9e\u9a8c\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cYoda1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u6b7b\u4ea1\u589e\u591a\u3001ROS\u8367\u5149\u589e\u5f3a\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u53bb\u6781\u5316\u3001\u7ebf\u7c92\u4f53\u51fa\u73b0\u76b1\u7f29\u53ca\u5d74\u65ad\u88c2\u7b49\u94c1\u6b7b\u4ea1\u5178\u578b\u8d85\u5fae\u7ed3\u6784\u6539\u53d8\uff08\u5747 P<0.05\uff09\uff1b\u800cGsMTx4\u7ec4\u53ef\u90e8\u5206\u9006\u8f6c\u4e0a\u8ff0\u6548\u5e94\uff08 P<0.05\uff09\u3002\u4f53\u5185\u5b9e\u9a8c\u793a\uff0cSCI\u540e\u810a\u9ad3\u7ec4\u7ec7\u4e2dPiezo1\u8868\u8fbe\u5448\u65f6\u5e8f\u6027\u4e0a\u8c03\uff0c\u672f\u540e7 d\u8fbe\u5cf0\u503c\uff08 P<0.05\uff09\uff0c\u4e14\u4e3b\u8981\u5b9a\u4f4d\u4e8eP2ry12\u9633\u6027\u5c0f\u80f6\u8d28\u7ec6\u80de\u3002\u4e0e\u635f\u4f24\u7ec4\u6bd4\u8f83\uff0c\u635f\u4f24+shPiezo1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u5185\u94c1\u6b7b\u4ea1\u6838\u5fc3\u86cb\u767dGPX4\u8868\u8fbe\u56de\u5347\u3001ACSL4\u8868\u8fbe\u4e0b\u964d\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5185ROS\u53caMDA\u6c34\u5e73\u964d\u4f4e\uff08 P<0.05\uff09\uff0c\u540c\u65f6\u4fc3\u708e\u56e0\u5b50TNF-\u03b1\u6c34\u5e73\u4e0b\u964d\u3001\u6297\u708e\u56e0\u5b50IL-10\u6c34\u5e73\u5347\u9ad8\uff08 P<0.05\uff09\uff1b\u6b64\u5916\uff0c\u81ea\u672f\u540e14 d\u8d77BMS\u8bc4\u5206\u663e\u8457\u9ad8\u4e8e\u635f\u4f24\u7ec4\uff08 P<0.05\uff09\uff0c\u4e14\u810a\u9ad3\u7ec4\u7ec7\u7ed3\u6784\u4fdd\u5b58\u76f8\u5bf9\u5b8c\u597d\uff0c\u7a7a\u6d1e\u9762\u79ef\u51cf\u5c0f\u3002.

In this study, we analyzed 188 ferroptosis-related differentially expressed genes (FRDEGs) at 7\u00a0day (7d) after SCI and identified GADD45A as a central gene in the post-SCI ferroptosis network, with a functional profile closely linked to apoptosis. GADD45A was markedly upregulated in injured spinal cord tissue. In vivo, GADD45A knockdown improved neurological recovery and promoted tissue repair by modulating markers of ferroptosis and apoptosis. In H2O2-treated PC12 cells, GADD45A knockdown reduced the expression of Cleaved Caspase-3, BAX, Cleaved Caspase-9, 4-HNE, and ACSL4, while increasing the expression of BCL-2, GPX4, FTH1, and FPN. It also attenuated H2O2-induced cellular injury. Mechanistically, GADD45A knockdown inhibited NF-\u03baB signaling and reduced nuclear translocation of NF-\u03baB-p65. These protective effects were reversed by the NF-\u03baB activator CU-T12-9. Collectively, these findings suggest that GADD45A promotes neuronal ferroptosis and apoptosis after SCI by regulating the NF-\u03baB pathway, and that GADD45A may be a potential therapeutic target for SCI."

In the central nervous system (CNS), most ferroptosis research has focused on neurons and glial cells, whereas the vulnerability of brain microvascular endothelial cells (BMECs) and its consequences for blood-brain barrier (BBB) integrity remain less clearly defined. Because BMECs form the vascular interface between the circulation and the brain parenchyma, ferroptotic injury in this cell population may represent an immunovascular mechanism through which endothelial redox stress is translated into barrier dysfunction and neuroinflammatory amplification. In this review, we summarize molecular pathways that may promote or restrain BMEC ferroptosis, including iron handling, antioxidant defense mediated by the solute carrier family 7 member 11 (SLC7A11)-glutathione peroxidase 4 (GPX4) axis and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, lipid peroxidation, and junctional remodeling. We then discuss how ferroptosis-associated endothelial injury may contribute to BBB leakage, damage-associated molecular pattern release, innate immune sensing, leukocyte recruitment, glial activation, and self-amplifying inflammatory feedback at the neurovascular interface. We organize the available literature according to the strength and cellular specificity of evidence, separating BMEC-specific findings, BBB-focused in vivo studies, indirect CNS evidence, and mechanistic analogies from non-CNS endothelial systems. Finally, we evaluate disease-specific evidence in ischemic stroke and selected neurodegenerative or inflammatory conditions, together with therapeutic strategies, BMEC-targeting considerations, candidate clinical biomarkers, and translational barriers for modulating endothelial ferroptosis. This review frames endothelial ferroptosis as a promising but incompletely established immunovascular link between BBB dysfunction and neuroinflammation, and highlights the need for BMEC-specific models, human BBB systems, endothelial ferroptosis biomarkers, biomarker-guided monitoring, BMEC-targeted delivery approaches, and careful evaluation of the physiological risks of systemic or prolonged ferroptosis blockade."

Although many therapeutic strategies have been explored to attenuate secondary injury, effective molecularly targeted interventions remain limited. Increasing evidence identifies signal transducer and activator of transcription 3 (STAT3) as a central signaling node in the neurochemical response to SCI. Recent studies indicate that STAT3 exhibits pronounced spatiotemporal and cell-type-specific activation after SCI. Depending on the upstream trigger and cellular compartment involved, STAT3 can amplify or restrain neuroinflammation, shape astrocyte and microglial reactivity, influence mitochondrial bioenergetics and oxidative stress, modulate ferroptosis and apoptosis, and alter the regenerative state of the injured spinal cord. In this review, we frame STAT3 not simply as a downstream effector of the JAK/STAT cascade, but as an integrative regulator of SCI neurochemistry that links cytokine-driven signaling to metabolic stress, glial remodeling, and axonal repair. We emphasize how injury phase, cell type, and subcellular localization influence STAT3-dependent outcomes, discuss emerging therapeutic strategies that converge on STAT3-centered pathways, and outline the key challenges that must be addressed for precise translational targeting."

Tetramethylpyrazine (TMP), a bioactive compound derived from traditional Chinese medicine, possesses a wide range of pharmacological activities and has demonstrated potential therapeutic effects in the treatment of SCI. Therefore, this article provides a comprehensive review of the mechanisms by which TMP promotes spinal cord repair. This review compiles a large body of in vitro, in vivo, and clinical studies, including a total of 86 publications documenting the effects of TMP on SCI. The results indicate that the mechanisms by which TMP exerts its effects in SCI treatment include promoting nerve regeneration, improving vascular dysfunction, exerting anti-inflammatory effects, inhibiting neuronal apoptosis, reducing oxidative stress, regulating iron metabolism, maintaining ion homeostasis, alleviating pyroptosis, and modulating autophagy. Through these mechanisms, TMP contributes to the restoration of spinal cord morphology, motor function, and electrophysiological parameters in experimental animal models. Clinical reports on the use of TMP injection for SCI are relatively limited, and its clinical efficacy requires further investigation. The combined application of nanotechnology or hydrogels provides an efficient targeted delivery and sustained-release system for TMP in the spinal cord, thereby significantly enhancing its bioavailability. Overall, TMP shows promising potential in SCI treatment and may serve as a valuable adjunctive therapeutic strategy."

Previous studies have demonstrated an association between increased level of iron in the lung and aging and age-related lung diseases including pulmonary fibrosis and asthma in the elderly (AIE). However, the mechanisms underlying the accumulation of iron with aging or AIE, or the cell types involved, remain understudied. In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling."

The present study aimed to develop a bioactive therapeutic platform based on an adipose-derived extracellular matrix (ECM) hydrogel incorporating cytokine-releasing PLGA microspheres to promote spinal cord repair. The hydrogel was fabricated from decellularized adipose tissue and combined with microspheres encapsulating interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and glial cell line-derived neurotrophic factor (GDNF) to achieve sustained cytokine delivery. Seventy-five male Sprague-Dawley rats were randomly allocated into five experimental groups, including control, SCI, hydrogel, microsphere, and Hydrogel\u2009+\u2009Mic groups. Tissue specimens were subsequently harvested from the lesion site for further analyses. In a rat model of SCI, treatment with the cytokine-releasing microsphere-loaded hydrogel significantly improved electrophysiological conduction and locomotor recovery compared with untreated SCI animals and groups receiving individual treatments. Molecular analyses demonstrated that the combined treatment markedly suppressed the expression of pro-inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Additionally, apoptosis-related markers showed substantial modulation, characterized by decreased Caspase-3 and Bax expression and increased Bcl-2 levels. The therapy also improved the oxidative balance by increasing antioxidant markers including GSH, SOD, and CAT while reducing the lipid peroxidation marker MDA. Furthermore, ferroptosis-associated biomarkers were significantly regulated, with elevated levels of GSH, GPX4, and SLC7A11 and reduced ACSL4 expression. Histological analyses revealed significant preservation of spinal cord architecture, reduced cavity formation, enhanced neuronal survival, and decreased glial activation in animals treated with the composite hydrogel system. Collectively, these findings demonstrate that adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres provides a multifunctional therapeutic strategy that attenuates inflammation, apoptosis, oxidative stress, and ferroptosis, ultimately promoting structural and functional recovery following spinal cord injury."

In this study, we aimed to identify and validate key genes associated with necroptosis in SCI using bulk RNA-seq data, followed by differential analysis and weighted gene coexpression network analysis (WGCNA). We identified several candidate necroptosis-related genes, and further least absolute shrinkage and selection operator (LASSO) regression highlighted five SCI-necroptosis differentially expressed genes (DEGs): toll-like receptor 4 (Tlr4), Nlrp3, Il1b, Tnfaip3, and Stat4. These genes were validated using RT-qPCR and western blot experiments. Our analysis revealed that necroptosis scores were significantly elevated following SCI. Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) analysis revealed that Tlr4 was upregulated in myeloid cells (microglia and macrophages) and played a pivotal role in triggering downstream necroptosis, which was confirmed by protein levels.

However, its direct involvement in cardiomyocyte injury mechanisms remains unclear. This study aimed to investigate the effects of Lp(a) on cardiomyocytes. A combination of in vitro cell culture and in vivo small animal models were used for investigations. Lp(a) induced ferroptosis through a redox-sensitive pathway via sequential p38 MAPK activation and p53-mediated transcriptional regulation. Exposure of AC16 human cardiomyocytes to Lp(a) triggered hallmark ferroptotic events, including intracellular Fe2+ accumulation, an increase in malondialdehyde (MDA) levels, and concurrent increases in p38 MAPK (p-p38) phosphorylation. Pharmacological blockade of p38 using SB203580 or siRNA-mediated p38 silencing significantly attenuated these ferroptotic markers, confirming the central role of p38 in sensitizing cardiomyocytes to ferroptosis. p38 activation drove the nuclear translocation of p53, with both pharmacological p53 inhibition (pifithrin-\u03b1) and genetic p53 knockdown effectively mitigating Lp(a)-induced lipid peroxidation and cell death. Furthermore, Lp(a) promoted an increase in intracellular reactive oxygen species (ROS) levels and initiated p38 phosphorylation, subsequently activating p53 to suppress SLC7A11 expression. These cellular findings were validated in vivo using Lp(a)-treated C57BL/6J mice, which recapitulated cardiac dysfunction, as indicated by characteristic ferroptotic markers: myocardial Fe2+/MDA elevation, glutathione/cysteine depletion, and p38-p53 axis activation. Lp(a) activates p38 by increasing intracellular ROS levels and promotes ferroptosis in cardiomyocytes via SLC7A11 inhibition, which depends on p53 activation."

While current evidence supports a strong association between CD14 expression, lytic cell death, and myeloid inflammatory responses, the direct causal role of CD14 in modulating these specific lipid peroxidation-dependent cell death pathways requires functional experimental confirmation.\n\n### [INTRODUCTION & JUSTIFICATION]\nSecondary injury following SCI involves complex, interconnected mechanisms including oxidative stress, inflammation, and programmed cell death. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI. Evidence from related models underscores that rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   CD14 is identified as the most robust candidate hub gene connecting lytic cell death signatures (pyroptosis, necroptosis, ferroptosis) to myeloid inflammatory activation post-SCI.\n*   Ferroptosis in microglia acts as an upstream driver of sustained neuroinflammation, linking iron dyshomeostasis and lipid peroxidation to inflammatory amplification.\n*   Ninjurin1 (NINJ1) functions as a terminal executor of plasma membrane rupture across multiple cell death modes, including ferroptosis and pyroptosis, positioning it as a structural nexus in lytic cell death.\n*   Recent data suggest that PANoptosis\u2014the synergistic activation of pyroptosis, apoptosis, and necroptosis via the PANoptosome\u2014is a major contributor to SCI secondary injury.\n*   Therapeutic modulation via adipose-derived ECM hydrogels loaded with cytokines or antioxidants (e.g., QM complexes) shows promise in suppressing ferroptosis and mitigating SCI-induced neuronal loss.\n*   Specific mechanosensitive channels like Piezo1 in microglia mediate mitochondrial dysfunction and ferroptosis, with their inhibition proving protective against secondary inflammatory damage.\n*   Sphingosine-1-phosphate receptor 2 (S1P2) signaling represents a distinct pathway driving neuronal ferroptosis following contusive SCI.\n*   GADD45A has been identified as a critical regulator that coordinates both ferroptosis and apoptosis via the NF-\u03baB pathway in SCI models.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures. Key findings were further evaluated using an external human SCI-related cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and published single-cell RNA-seq data. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. External validation in a human SCI-related peripheral blood cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and single-cell reanalysis further supported the upregulation of CD14 and its association with myeloid inflammatory activation and pyroptosis-, necroptosis-, and ferroptosis-related signatures. Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI.\n\nID: 42510609\nTitle: Plant-Derived Natural Compounds and Nrf2-Centered Redox Signaling in Intracerebral Hemorrhage: Evidence Grading, Mechanistic Boundaries, and Translational Challenges.\nAbstract: Intracerebral hemorrhage (ICH) is a devastating stroke subtype in which secondary brain injury is driven by oxidative stress, iron overload, ferroptosis, neuroinflammation, blood-brain barrier disruption, and defective hematoma clearance. Nrf2 is a redox-sensitive transcription factor that coordinates antioxidant defense, iron handling, inflammatory regulation, and neurovascular unit protection through downstream effectors such as HO-1, NQO1, GPX4, and SLC7A11. Plant-derived natural compounds have been widely investigated in experimental ICH models; however, increased Nrf2 expression or nuclear translocation alone does not establish Nrf2-dependent neuroprotection. Here, we critically appraise preclinical evidence linking plant-derived natural compounds to Nrf2-centered signaling in ICH and classify the evidence into three levels: causal Nrf2-dependent evidence, Nrf2-associated evidence, and indirect or context-transferred evidence. Representative flavonoids, phenolics, terpenoids, lignans, steroidal lactones, and other bioactive compounds are evaluated with attention to ICH-model relevance, causal pathway validation, pharmacokinetic limitations, brain exposure, and therapeutic window. Current evidence indicates that only a limited subset of compounds has been validated by genetic or pharmacological Nrf2 inhibition, whereas most remain supported by pathway association rather than causality, and preclinical studies rely predominantly on young healthy rodent models with early post-ICH intervention. Notably, no compound currently reaches relatively high translational priority because perihematomal brain exposure, delayed-treatment efficacy, and long-term safety evidence remain largely unavailable. We therefore propose an evidence-based prioritization framework integrating Nrf2 causality, ICH-specific efficacy, brain bioavailability, and translational readiness. This review clarifies the mechanistic boundaries of Nrf2-targeted natural compounds and outlines priorities for rigorous translational research in ICH.\n\nID: 42496936\nTitle: Neurotoxic effects of dietary glutamate in glaucoma and potential nutritional and pharmacological therapies: a scoping review.\nAbstract: To synthesize the available evidence on the relationship between dietary glutamate or glutamatergic metabolism and glaucomatous neurodegeneration, with emphasis on biomarkers, retinal injury mechanisms, and nutritional, antioxidant, or pharmacological strategies with neuroprotective potential. This study was conducted as a systematic and bibliometric literature review following the PRISMA 2020 logic of identification, screening, eligibility, and inclusion. Searches were performed in Web of Science, Scopus, and PubMed for studies published in English between 2020 and 2025. The search strategy combined terms related to glaucoma or ocular neurodegeneration, the glutamatergic axis, and biomarkers, mechanisms, or interventions. After screening and full-text assessment, 39 studies were included in the systematic synthesis. Due to methodological heterogeneity, the evidence was synthesized narratively and comparatively, without meta-analysis. The included studies were organized into six thematic clusters: metabolomic, transcriptomic, and diagnostic biomarkers; pharmacological and neuroprotective interventions; nutritional, antioxidant, and natural-compound neuroprotection; oxidative stress, mitochondrial dysfunction, and regulated cell death; neuroinflammation and glia-mediated retinal injury; and glutamatergic excitotoxicity and neurotransmitter imbalance. The evidence indicates that glutamate-related mechanisms in glaucoma are mainly associated with endogenous glutamatergic metabolism, excitotoxicity, impaired glutamate clearance, glutamate-glutamine homeostasis, oxidative and nitrosative stress, mitochondrial dysfunction, ferroptosis, neuroinflammation, and retinal ganglion cell vulnerability. None of the 39 included studies directly evaluated dietary glutamate or monosodium glutamate as the main exposure. The available evidence does not support a direct conclusion that dietary glutamate or MSG intake contributes to glaucoma onset or progression. Instead, current findings mainly support an indirect mechanistic relationship between endogenous glutamatergic dysregulation and glaucomatous neurodegeneration. Pharmacological, antioxidant, metabolic, and natural-compound strategies show neuroprotective potential, particularly in experimental models, but clinical and translational studies are still needed to clarify the role of dietary exposure, glutamate-glutamine metabolism, and targeted neuroprotective interventions in glaucoma.\n\nID: 42485915\nTitle: Stearoyl CoA desaturase 1 deficiency increases ferroptosis susceptibility in chicken embryonic liver cells.\nAbstract: Ferroptosis is an iron-dependent form of programmed cell death driven by lipid peroxidation. It is increasingly recognized as a contributor to liver cell injury. Stearoyl-CoA desaturase 1 (SCD1) is a rate-limiting enzyme in monounsaturated fatty acid synthesis. It plays a key role in maintaining lipid homeostasis and may affect cellular susceptibility to ferroptosis. However, it remains unclear whether SCD1 restrains ferroptosis-associated injury in chicken embryonic liver (CEL) cells. Therefore, this study aimed to investigate the role of SCD1 in regulating ferroptosis susceptibility and cellular injury related to ferroptosis in CEL cells, with a focus on its effects on lipid metabolism, oxidative stress, and iron homeostasis. The results showed that SCD1 knockdown reduced intracellular lipid droplet area, triglyceride, and total cholesterol levels in CEL cells (P < 0.05). In addition, SCD1 knockdown induced mitochondrial ultrastructural changes associated with ferroptosis, including mitochondrial shrinkage, increased membrane density, and cristae disruption. It also aggravated oxidative stress, as shown by increased reactive oxygen species, oxidized glutathione, and malondialdehyde levels and decreased glutathione content (P < 0.05). SCD1 knockdown reduced cell viability, whereas oleic acid or ferrostatin-1 treatment partially reversed this decrease (P < 0.05). Moreover, SCD1 knockdown increased ACSL4 expression and decreased SLC7A11, GPX4, and Nrf2 expression at both the mRNA and protein levels (P < 0.05). SCD1 knockdown further reduced mitochondrial membrane potential and increased lipid peroxidation, intracellular Fe\u00b2\u207a levels, and total iron content (P < 0.05). In contrast, SCD1 overexpression increased lipid accumulation, reduced reactive oxygen species levels, increased glutathione content, increased SLC7A11, GPX4, and Nrf2 expression, and decreased ACSL4 protein expression (P < 0.05) without significantly affecting ACSL4 mRNA expression. These findings suggest that SCD1 regulates the susceptibility of CEL cells to ferroptosis and exerts a protective effect by improving lipid metabolism, antioxidant defenses, and mitochondrial function, indicating that SCD1 is a key regulatory factor in maintaining the homeostasis and health of chicken liver.\n\nID: 42474555\nTitle: Neural network-enhanced investigation of ferroptosis and druggability in early-onset alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder which is multifactorial in nature. Some of its characteristics are slow cognitive decline, memory problems and behavioral changes. AD patient brains show a progressive synaptic toxicity, autophagy, neuroinflammation, excess generation of reactive oxygen species (ROS), neuronal death and oxidative stress, which occurs due to disrupted metal homeostasis along with tau and amyloid-\u03b2 protein deposition. Notably, lipid peroxidation, iron buildup and elevated oxidative stress in AD brains suggest a possible molecular\u00a0connection between ferroptosis and AD neurodegeneration. This study explores the genetic and bioinformatics perspective on the relationship between ferroptosis and AD aiming to identify potential therapeutic potential biomarkers using Neural network (NN) and Machine learning models. Six ferroptosis related genes were found to be differentially expressed in AD. Further machine learning analysis shortlisted four key biomarker genes. An NN-based diagnostic prediction model was developed and validated using AUC-ROC anaysis, which gave high diagnostic values (AUC- 0.92) in the analysis. The findings highlight a strong correlation between ferroptosis and altered metabolic functions in AD. miRNA-gene interaction analysis revealed that two biomarker genes, CYBB and ACSL4 can be regulated by several regulatory miRNAs i.e., hsa-miR-146-5p, hsa-miR-106b-5p, hsa-miR-223-3p, hsa-miR-155-5p, hsa-miR-34a-5p, hsa-miR-125b-5p and hsa-miR-27a-3p suggesting their potential as early diagnostic potential biomarkers. Immune microenvironment analysis revealed strong neuroinflammatory responses in AD with increased infiltration of macrophages (M0, M1 and M2), monocytes and multiple T cell subsets. This heightened immune activity may be driven by ferroptosis-induced oxidative stress contributing to neuronal death. Furthermore, druggability of these targets was evaluated and several drugs were identified that may be potentially repurposed for therapeutic intervention in AD pathogenesis. This study presents a diagnostic predictive model integrating gene expression, miRNA regulation and immune infiltration analysis, offering a novel perspective on early AD detection. The identified ferroptosis-related potential biomarkers and regulatory miRNAs could serve as valuable tools for clinical diagnosis and targeted therapeutic intervention, advancing personalized treatment strategies for Alzheimer's disease.\n\nID: 42468577\nTitle: Targeting neuroinflammation and neurodegeneration in Parkinson's disease: Emerging natural and synthetic therapeutic strategies.\nAbstract: Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder worldwide. It is associated with the ongoing degeneration of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies that contain \u03b1-synuclein. These pathological changes lead to abnormalities of motor symptoms (tremor, rigidity, bradykinesia) and non-motor symptoms (cognitive decline, sleep abnormalities, psychiatric abnormalities). The pathogenesis of PD is complex and multifactorial, involving interconnected mechanisms such as oxidative stress, mitochondrial dysfunction, neuroinflammation, impaired autophagy, ferroptosis, and genetic factors. To develop effective therapeutic interventions, these pathways need to be understood. Current treatments, such as levodopa and deep-brain stimulation (DBS), are symptom-based and do not break disease progression. Thus, considerable research efforts have been geared towards finding disease-modifying therapeutic strategies. Natural bioactive compounds, gene-based therapies, stem cell-based therapies, and nanotechnology-assisted drug delivery systems are promising alternatives as suggested by recent advances. Antioxidant compounds like curcumin, resveratrol, and epigallocatechin gallate (EGCG) show promising antioxidant and neuroprotective effects, and nanomedicine provides boosted delivery to the brain and targeted drug distribution. In future clinical applications, these new strategies could help to more effectively and permanently manage PD.\n\nID: 42455768\nTitle: A multi-target nano-therapy against cerebral ischemia/reperfusion injury via combinatorial inhibition of neuroinflammation and pyroptosis.\nAbstract: Background & purpose: ischemic stroke reperfusion injury involves a vicious cycle of neuroinflammation, pyroptosis, and oxidative stress. Single-target therapies have limited efficacy. In this study, we aimed to develop an actively targeted, multi-drug combinatorial nano-platform for coordinated intervention against ischemia/reperfusion (I/R) injury. Methods: we synthesized CX3CL1-functionalized ZIF-8 nanoparticles co-loaded with disulfiram (DFL, a GSDMD-N pore inhibitor), paquinimod (PAQ, a TLR4/NF-\u03baB inhibitor), and siNINJ1 (inhibiting membrane rupture). The nanoparticles were systematically characterized. Their neuroprotective effects and mechanisms were evaluated using a transient middle cerebral artery occlusion (tMCAO) mouse model and an oxygen-glucose deprivation/reoxygenation (OGD/R) co-culture model in vitro. Results: the nanoparticles exhibited pH-responsive release and active targeting to the ischemic penumbra. In vivo and in vitro results demonstrated that they synergistically inhibited the TLR4/NF-\u03baB/NLRP3 signaling axis and pyroptosis execution (GSDMD, caspase-1), promoted microglial polarization towards the M2 phenotype, reduced pro-inflammatory cytokines (IL-6, TNF-\u03b1), and alleviated oxidative stress and neuronal apoptosis, ultimately leading to significantly reduced infarct volume and improved neurological recovery. Conclusion: we successfully developed an \"active targeting-multi-drug synergy-cascade intervention\" nano-therapeutic platform that effectively mitigates cerebral I/R injury through multi-pathway coordination, offering a novel combinatory strategy for ischemic stroke treatment.\n\nID: 42451075\nTitle: Maltol Protects Neuronal Cells by Alleviating Chronic Neuroinflammation, Pyroptosis, and Ferroptosis via HSP70 Upregulation in Microglia.\nAbstract: Objectives: Neuroinflammation is recognized as a significant characteristic of Alzheimer's disease (AD). Currently, there is a notable absence of effective pharmacological agents to prevent or treat neuroinflammatory processes associated with AD. Heat shock protein 70 (HSP70) is pivotal in the progression of neuroinflammation. In this study, we explored the potential of maltol, a Maillard reaction product derived from red ginseng, as a therapeutic agent for neuroinflammation. Methods: In vitro, HMC3 microglial cell models were developed to examine the regulatory effects of gradient concentrations of maltol (12.5, 25, 50 \u03bcM) on the TLR4/MyD88/NF-\u03baB p65 signaling pathway, neuroinflammation, and pyroptosis. Analyses of the GEO database and Gene Set Enrichment Analysis (GSEA) were performed to identify the core targets of maltol, followed by HSP70 gene silencing experiments to validate the targeted regulatory mechanism. Results: Maltol significantly mitigated LPS-induced neuronal damage and cognitive deficits in mice. It effectively suppressed microglia-mediated neuroinflammation and pyroptosis, reversed oxidative stress-induced neuronal ferroptosis, and inhibited neuronal apoptosis. In vitro experiments demonstrated that maltol obstructed TLR4/MyD88 binding, thereby inhibiting NF-\u03baB p65-mediated neuroinflammation and pyroptosis, while also alleviating excessive ROS accumulation to enhance oxidative stress and ferroptosis. Bioinformatics analysis identified HSP70 as a crucial target for the anti-inflammatory and antioxidant effects of maltol. Subsequent gene silencing experiments confirmed that maltol exerted its inhibitory effects on LPS-induced neuroinflammation and pyroptosis in an HSP70-dependent manner. Conclusions: Maltol exhibits significant protective effects against Alzheimer's disease-related neuroinflammation, oxidative stress, pyroptosis, and ferroptosis through the targeting of HSP70. This study elucidates the molecular mechanisms by which maltol improves neuroinflammatory injury and provides a novel theoretical foundation and therapeutic strategy for the intervention of Alzheimer's disease neuroinflammation using traditional Chinese medicine.\n\nID: 42448018\nTitle: Senegenin mitigates neuroinflammation, pyroptosis, and apoptosis in cerebral ischemia via inhibiting STING and downstream inflammatory pathway.\nAbstract: Ischemic stroke continues to be a major cause of mortality and persistent disability, with neuroinflammation at the central stage of cell death signaling. The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders.\n\nID: 42446837\nTitle: Molecular Regulation of Pyroptosis in Alzheimer's Disease: Linking Neuroinflammation, Cell Death, and Therapeutic Targeting.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by profound cognitive decline, wherein chronic neuroinflammation plays a pivotal pathogenic role. Central to this inflammatory milieu is pyroptosis, a highly inflammatory form of programmed lytic cell death mediated by gasdermin proteins. This comprehensive review provides an in-depth synthesis of the cellular and molecular mechanisms underlying pyroptosis in AD. We detail the distinct roles of microglia as primary initiators responding to amyloid-beta (A\u03b2) and tau aggregates, alongside the specific vulnerabilities of neurons facing oxidative stress, astrocytes impacting metabolic support, and endothelial cells whose pyroptotic death contributes directly to blood-brain barrier disruption. At the molecular level, the priming and activation of the NLRP3 and NLRP1 inflammasomes by diverse triggers, including classical markers like A\u03b2, environmental neurotoxicants and metabolic stressors, converge on caspase-1 and caspase-8 activation. This cascade culminates in gasdermin D (GSDMD) and gasdermin E (GSDME) pore formation, leading to cellular lysis and the massive release of pro-inflammatory cytokines such as IL-1\u03b2 and IL-18. Furthermore, this paper explores the emerging and critical concept of PANoptosis, highlighting the intricate crosstalk between pyroptosis, apoptosis, and necroptosis within PANoptosome complexes triggered by mitochondrial dysfunction. We evaluate current and prospective therapeutic strategies, ranging from multi-target natural and traditional herbal remedies to advanced nanomedicine, synthetic small molecules, and epigenetic gene therapies. By integrating insights from blood-based pyroptosis-associated molecular signatures and advanced targeted drug delivery systems, we emphasize the critical need for personalized, multi-targeted approaches to successfully harness pyroptosis modulation in the clinical management and treatment of AD.\n\nID: 42443164\nTitle: Lineage-specific Nrf2 signaling orchestrates distinct neuroprotective mechanisms in acute ischemic stroke.\nAbstract: Nuclear factor erythroid 2-related factor 2 (Nrf2), a key antioxidant transcription factor, shows neuroprotective potential in ischemic stroke (IS); however, its cell type-specific functions across different neural lineages remain partially understood. This study innovatively employs a comparative knockout paradigm, utilizing neural lineage knockout (Nrf2flox/flox; Nestin-Cre, targeting neural progenitor cells and their derived lineages) and astrocyte-biased knockout (Nrf2flox/flox; GFAP-Cre) mouse models, combined with an in vitro co-culture system, to elucidate the lineage-dependent and differential protective mechanisms of Nrf2 in acute IS (AIS). Results demonstrated that both knockout models exacerbated neurological deficits, increased cerebral infarct volumes, and reduced cerebral blood flow. However, a marked phenotypic divergence was observed. The Nestin-Cre model exhibited more severe neurological deterioration, associated with dysregulated iron metabolism, enhanced lipid peroxidation, and aggravated neuroinflammation, suggesting a predominant role for neuronal Nrf2 in counteracting ferroptosis and neuroinflammatory responses. In contrast, the GFAP-Cre model did not induce ferroptosis but promoted neurotoxic A1-type astrocyte polarization and enhanced inflammatory injury via NF-\u03baB pathway activation. This finding underscores the unique function of astrocytic Nrf2 in modulating the neuroinflammatory microenvironment. These cell-type-specific effects were further validated in an in vitro oxygen-glucose deprivation/reoxygenation (OGD/R) model. Through this cross-lineage comparative analysis, our study systematically elucidates, for the first time, the distinct protective mechanisms of Nrf2 in neurons and astrocytes, thereby advancing understanding of its functional heterogeneity and providing a novel theoretical basis for developing cell-type-biased, Nrf2-targeted therapeutic strategies.\n\nID: 42439630\nTitle: Redox-Mitochondria-Immune Network Dysregulation in Schizophrenia: From Selective Cellular Vulnerability to Circuit Dysfunction.\nAbstract: Oxidative stress has been recognized as a repeatedly validated pathophysiological factor in schizophrenia, but its mechanistic role and translational relevance remain incompletely defined. Prior work has advanced redox dysregulation, neuroinflammation, and NMDA receptor hypofunction as a putative central hub in schizophrenia. This narrative review proposes an evidence-weighted redox-mitochondria-immune framework that integrates peripheral biomarkers, magnetic resonance spectroscopy, postmortem findings, and preclinical mechanisms while explicitly distinguishing established observations from candidate pathways. Existing studies support increased oxidative damage and altered antioxidant buffering in schizophrenia, particularly involving the glutathione system. However, these abnormalities are neither uniform across disease stages nor equally represented across patient subgroups, and may be markedly prominent only in certain biological subgroups. Mechanistically, redox imbalance may interact with mitochondrial bioenergetic deficits and innate immune signaling; however, pathway-specific links such as cGAS-STING activation, nitrosative/peroxynitrite stress, and GPx4-ferroptosis should currently be treated as testable extensions rather than validated human mechanisms in schizophrenia. Importantly, the pathological consequences of oxidative stress are unlikely to be cell-type neutral. Parvalbumin-positive interneurons and oligodendrocyte lineage cells are more vulnerable because of their high metabolic load, limited antioxidant buffering capacity, and lipid/iron-related susceptibility, thereby providing a mechanistic bridge to excitation-inhibition imbalance, myelin abnormalities, and reduced circuit synchrony. Microglial redox-inflammatory signaling may further exacerbate these processes. On the basis of this framework, we argue that the key for future research is not to continue demonstrating the universality of oxidative stress, but to improve the translational efficiency. Biomarker-guided stratification, stage-sensitive study designs, and cell-type-informed therapeutic strategies may therefore provide a more productive path toward redox-targeted interventions in schizophrenia.\n\nID: 42427876\nTitle: Grey matter degeneration during multiple sclerosis is linked to activation of neuronal necroptosis by oxidized phosphatidylcholines.\nAbstract: Oxidized phosphatidylcholines (OxPCs) are biomarkers of oxidative stress found in grey matter (GM) lesions during multiple sclerosis (MS), yet their distinct role in GM neurodegeneration remains undefined. Here we report that stereotaxic OxPC deposition in the mouse spinal cord GM induces age dependent neuroinflammation and neurodegeneration. Microglia are the predominant macrophages responding to OxPC induced GM lesions and help to mitigate acute neurodegeneration. Neuronal necroptosis activation in mouse GM lesions and neuronal upregulation of OxPCs and necroptosis activation in MS GM lesions suggest OxPC induced necroptosis promote GM degeneration during MS. In support, necroptosis inhibition ameliorates OxPC induced GM neuron loss. Finally, iron(ii)-containing heme deposition in the GM induces both OxPC formation and neuronal necroptosis activation, suggesting an endogenous upstream mechanism for generating neurotoxic OxPCs. These results highlight a plausible link between heme deposition, lipid peroxidation, and neuronal loss, and that necroptosis inhibition could help prevent GM neurodegeneration during MS.\n\nID: 42421041\nTitle: Advances in electroacupuncture for perioperative neurocognitive disorders: mechanisms and clinical evidence.\nAbstract: Perioperative neurocognitive disorders (PND), including postoperative delirium, delayed neurocognitive recovery, and postoperative cognitive dysfunction, are common complications in older surgical patients and are associated with impaired recovery, reduced quality of life, and increased postoperative morbidity. Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND.\n\nID: 42403480\nTitle: The ferroptosis-mediated domino effect: metabolic crosstalk from intervertebral disc degeneration to spinal deformity and cord injury: a mini review.\nAbstract: Spinal degeneration, spinal deformity, and spinal cord injury (SCI) are classically managed as discrete biomechanical or neurological entities. However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse.\n\nID: 42391929\nTitle: Development of potent BChE/Nrf2 modulators for Alzheimer's disease treatment via dual suppression of ferroptosis.\nAbstract: Targeting multiple pathological mechanisms holds significant potential for Alzheimer's disease (AD) therapy. Here, we designed 50 hybrids combining the benzimidazole-aminofurazan scaffold of a BChE inhibitor (S06-1064) with the 1,2,4-oxadiazole moiety of an Nrf2 activator (6). After four optimization rounds, S27-1046 and S27-1047 emerged as potent, selective BChE inhibitors and Nrf2 activators (S27-1046: eqBChE IC50\u202f=\u202f2.51\u202f\u00b1\u202f1.51\u202fnM, hBChE IC50\u202f=\u202f128.30\u202f\u00b1\u202f16.89\u202fnM, FP IC50\u202f=\u202f188.20\u202f\u00b1\u202f57.11\u202fnM, 4.73-fold ARE induced fold at 20\u202f\u03bcM; S27-1047: eqBChE IC50\u202f=\u202f7.16\u202f\u00b1\u202f2.96\u202fnM, hBChE IC50\u202f=\u202f296.10\u202f\u00b1\u202f55.78\u202fnM, FP IC50\u202f=\u202f36.87\u202f\u00b1\u202f23.07\u202fnM, 7.42-fold ARE induced fold at 20\u202f\u03bcM). They directly bind Keap1, disrupt Keap1-Nrf2 interaction, enhance antioxidant enzyme expression, and activate the GSH-GPX4 axis to inhibit A\u03b2-induced ferroptosis. Both compounds also protect against oxidative stress and neuroinflammation. S27-1047 showed superior Nrf2 activation and Keap1 binding, thus was selected for in vivo evaluation. In an A\u03b2-induced AD mouse model, S27-1047 significantly improved cognition, outperforming mono- or combination therapies. It has 12.62% oral bioavailability and crosses the BBB. This work presents multi-target agents targeting BChE, Nrf2, and ferroptosis for effective AD therapy.\n\nID: 42386088\nTitle: Trifluoro-icaritin mitigates spared nerve injury-induced neuropathic pain by upregulating spinal \u03b17nAChR through suppressing ferroptosis.\nAbstract: Epimedium spp. Has served as a traditional analgesic herbal medicine in Chinese medicine for over two thousand years. Its active metabolite, icariin (ICT), along with its fluorinated derivative, trifluoro-icaritin (ICTF), has been shown in our previous research to alleviate neuropathic pain induced by spared nerve injury (SNI) through an \u03b17 nicotinic acetylcholine receptor (\u03b17nAChR)-dependent pathway. Neuropathic pain remains a significant and unresolved health issue. Ferroptosis has recently been identified as a key, yet insufficiently explored, aspect, and the interaction between ferroptosis and the spinal cholinergic anti-inflammatory receptor \u03b17nAChR remains entirely unknown. This study aims to investigate whether ferroptosis serves as a critical mechanistic link between \u03b17nAChR and the analgesic effects of ICTF. A spared nerve injury (SNI) rat model was established to investigate neuropathic pain. Pain-related behaviors were assessed through paw withdrawal threshold (PWT) and CatWalk gait analysis. Western blotting and immunofluorescence were employed to detect protein expression and co-localization. Moreover, transcriptomic sequencing of spinal cord tissue was conducted to identify candidate pathways. To establish causality, two independent reverse validation approaches were utilized, including the administration of the ferroptosis agonist Erastin and intrathecal injection of adeno-associated virus to knock down \u03b17nAChR. Transcriptomic analysis revealed a significant enrichment of ferroptosis-associated gene signatures in SNI rat spinal cords, characterized by marked upregulation of pro-ferroptotic genes, including Cybb, Sat1, and Hmox1. Concurrently, SNI markedly decreased neuronal expression of \u03b17nAChR and the ferroptosis-inhibitory enzyme GPX4. Treatment with ICTF (5.0\u202fmg/kg, intraperitoneally), the optimal dosage screened in our prior study, effectively counteracted these alterations, accompanied by attenuation of iron overload, lipid peroxidation, and oxidative stress within the spinal cord. Reverse validation further demonstrated that Erastin abolished the analgesic and motor-improving effects of ICTF, while concurrently suppressing \u03b17nAChR and GPX4 expression. Moreover, \u03b17nAChR knockdown produced comparable effects, negating ICTF-mediated benefits and further reducing GPX4 levels. We found that spinal ferroptosis is markedly activated in SNI rats, thereby exacerbating neuroinflammation and mechanical allodynia. Importantly, ferroptosis suppresses the expression of \u03b17nAChR, while ICTF interrupts this vicious cycle by upregulating \u03b17nAChR, inhibiting ferroptosis-related iron accumulation, lipid peroxidation, and the downregulation of GPX4, ultimately alleviating SNI-induced neuropathic pain. This study offers a scientific interpretation of the traditional use of Epimedium-derived active compounds for treating neuropathic pain at the modern molecular mechanism level.\n\nID: 42385643\nTitle: Vagus nerve stimulation alleviates anxiety by inhibiting ferroptosis-related neuronal damage through \u03b17nAChR.\nAbstract: Anxiety disorder is a highly prevalent mental health issue globally; however, existing therapeutic approaches have limitations such as significant side effects and poor compliance. Vagus nerve stimulation (VNS) has been used to treat emotional distress, while the underlying mechanisms remain elusive. A chronic restraint stress (CRS)-induced mouse anxiety model in vivo and a corticosterone (CORT)-induced neuronal cell death model in vitro were employed, followed by treatment with vagus nerve stimulation and \u03b17nAChR agonists or antagonists. Anxiety levels were assessed using the open field test (OFT), elevated plus maze (EPM), and novelty-suppressed feeding test (NSFT). Histopathological staining and immunofluorescence staining were performed to detect the pathological changes of neuronal injury in anxiety disorders. Western blot was conducted to measure the protein expression levels of GPX4, SLC7A11, and ACSL4. Enzyme-linked immunosorbent assay (ELISA) was used to measure the expression levels of anxiety-related pro-inflammatory cytokines, while quantitative real-time polymerase chain reaction (qPCR) was employed to detect the mRNA expression levels of GPX4, SLC7A11, and ACSL4. In this study, we found that VNS significantly alleviated anxiety-like behaviors, reduced hippocampal ferroptosis-related damage and inflammatory responses in anxiety mice. \u03b17nAChR antagonist abolished VNS-mediated protective effects against ferroptosis-related neuronal damage and anxiety, while \u03b17nAChR agonists produced similar anxiolytic effects to VNS. Mechanistically, VNS activated \u03b17nAChR signaling, thereby upregulating the expression of GPX4 and SLC7A11, inhibiting ACSL4-mediated lipid peroxidation, and ultimately suppressing anxiety-induced ferroptosis-related neuronal damage. This study reveals a novel mechanism underlying the anxiolytic effect of VNS, that is, by activating \u03b17nAChR signal, VNS inhibits CRS-induced ferroptosis-related neural damage. Our findings provide new insights into mechanism of anxiety disorders and lay a theoretical foundation for the clinical application of VNS.\n\nID: 42382985\nTitle: Ferroptosis in intracerebral hemorrhage: a bibliometric overview of mechanisms and future directions.\nAbstract: Research on ferroptosis in intracerebral hemorrhage (ICH) has expanded rapidly in recent years, but the overall knowledge structure and research trends of this field remain unclear. A total of 254 publications related to ferroptosis in ICH from the Web of Science Core Collection and Scopus databases (2014-2025) were analyzed using Bibliometrix, VOSviewer, and CiteSpace. Bibliometric analyses were performed to evaluate publication trends, research hotspots, collaboration networks, and emerging themes. Publication output increased markedly after 2020, reflecting growing attention to ferroptosis-related brain injury after ICH. China contributed nearly 80% of the publications, although international collaboration remained relatively limited. Keyword evolution and co-citation analyses showed that the research focus gradually shifted from general cell death pathways toward more specific mechanisms involving iron metabolism, lipid peroxidation, GPX4-mediated antioxidant regulation, and neuroinflammation. Several highly cited studies published after 2017 played important roles in shaping the development of this field. Recent studies have increasingly focused on downstream pathological processes and potential therapeutic strategies. This study summarizes the major research themes and evolving directions of ferroptosis research in ICH and provides a useful reference for future mechanistic and translational studies.\n\nID: 42377703\nTitle: Clemastine ameliorates ulcerative colitis-induced cognitive impairment by restoring PI3K/Akt/GSK-3\u03b2 signaling and suppressing ferroptosis.\nAbstract: Ulcerative colitis (UC) is a refractory inflammatory bowel disease with ongoing colonic inflammation and extra-intestinal manifestations, including cognitive impairment. In this study, we evaluated the peripheral and central effects of clemastine on cognitive impairment induced by UC using an acetic acid (1\u00a0ml, 4% v/v) model with emphasis on the role of PI3K/Akt/GSK-3\u03b2 signaling, ferroptosis, and autophagy in its possible mediated neuroprotection. Clemastine revealed a dose-dependent improvement of colonic damage linked with UC, as demonstrated by inhibition of TNF-\u03b1, IL-1\u03b2, and caspase-3 levels along with upregulation of claudin-1 expression. Importantly, the preservation of gut membrane integrity was associated with amelioration of UC-induced systemic inflammation together with restoration of PI3K/Akt/GSK-3\u03b2 signaling in the brain. Additionally, the neuroprotective actions of clemastine included the prevention of neuronal injury and death as evidenced by inhibition of oxidative stress markers and microglial activation (Iba-1 expression), which could exacerbate the neuroinflammatory response. Concurrently, inhibition of the pathological autophagic dysfunction and ferroptosis profile by clemastine, as clarified by LC3-II downregulation and LC3-I and GPX4 upregulation, led to behavioral and cognitive improvements, which were proven by decreased levels of A\u03b2 and tau protein. Importantly, by crossing the BBB, clemastine could exert additional anti-inflammatory and neuroprotective effects by affecting the central assessed pathways. In conclusion, these findings clarify the pivotal role of clemastine in the management of colonic inflammation-associated cognitive decline through modulating multiple and interacting peripheral and central pathways to provide its potent neuroprotection.\n\nID: 42348969\nTitle: Neurotoxicity of antimony: A review of epidemiological evidence and the underlying molecular mechanisms.\nAbstract: Antimony (Sb) is a toxic metalloid and a global pollutant. Sb exposure is known to cause pulmonary, cardiovascular, liver and kidney damage, as well as cancer. In addition, data showing neurotoxic effects of Sb have been also obtained recently. Therefore, the objective of the present review was to discuss existing epidemiological findings linking Sb exposure to brain diseases and the underlying molecular mechanisms of Sb neurotoxicity. Laboratory findings revealed neurotoxic effects of high-dose Sb exposure. Specifically, in vitro and in vivo studies show that Sb induces neuronal apoptosis through induction of oxidative stress, altered Akt/mTOR and Wnt/\u03b2-catenin signaling, and potentially increased Ca2\u202f+ flux. Activation of ferroptosis due to reactive oxygen species (ROS) overproduction, autophagic GPX4 degradation, and NCOA4-mediated ferritinophagy also appear to mediate Sb neurotoxicity. Other mechanisms linked to adverse effects of Sb in brain include altered neurotransmitter metabolism, neuroinflammation, as well as impaired gut-brain axis and neurogenesis. Epidemiological findings show also that Sb exposure, both in single metal and multiple metal exposure models, is associated with increased risk of depression, sleep disorders, anxiety, cognitive dysfunction, and neurodevelopmental disorders like autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD), although controversial data exist. Evidence showing that maternal Sb exposure is also associated with adverse neurodevelopmental outcome in children also exists. While the precise role of Sb exposure in development of neurological diseases has yet to be established due to limited data, a complex of epidemiological and laboratory findings show that Sb should be considered a potential environmental neurotoxicant.\n\nID: 42341849\nTitle: Microglial ferroptosis mediated neuroinflammation in central nervous system diseases.\nAbstract: Microglial ferroptosis has become an important pathological mechanism in studies of central nervous system (CNS) diseases. Rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation. In this review, we summarize the molecular mechanisms by which microglial ferroptosis mediates neuroinflammatory responses, with a focus on iron homeostasis disruption, lipid peroxidation and ROS amplification, collapse of the GPX4-dependent antioxidant defense, mitochondrial ROS generation, and inflammasome activation. We further classify related CNS diseases into three categories according to disease course and pathological features: chronic neurodegenerative and demyelinating diseases, acute CNS injuries, and neuropsychiatric or systemic inflammation-related brain dysfunction. Within this framework, we compare the pathological significance of microglial ferroptosis across different disease contexts. We also discuss potential therapeutic strategies targeting iron homeostasis, lipid peroxidation, antioxidant defenses, inflammatory amplification networks, and microglia-specific delivery systems. Finally, we address current challenges in the field, including insufficient cell-type specificity, inconsistent detection criteria, disease-stage heterogeneity, and barriers to clinical translation. This review provides an integrated perspective on the mechanisms by which microglial ferroptosis drives neuroinflammation and highlights its potential relevance for precision intervention in CNS diseases.\n\nID: 42341847\nTitle: Edaravone attenuates ACSL4-dependent ferroptosis in spinal motor neurons following cardiac arrest in rats.\nAbstract: The contribution of acute spinal motor neuron injury following cardiac arrest (CA) remains poorly understood. This study aimed to investigate the role of ferroptosis in CA-induced spinal cord injury and to evaluate the neuroprotective effects of edaravone. Asphyxial CA was induced in rats for 5\u202fmin, followed by resuscitation. Edaravone was administered immediately after the return of spontaneous circulation (ROSC). At 24\u202fh post-ROSC, The CA group exhibited significant hindlimb motor deficits and reduced survival rates. Histological analysis revealed selective injury of choline acetyltransferase (ChAT)-positive motor neurons in the lumbar spinal cord, accompanied by mitochondrial shrinkage and membrane rupture, which are characteristic of ferroptosis. Immunofluorescence demonstrated a selective upregulation of the pro-ferroptotic enzyme acyl-CoA synthetase long-chain family member 4 (ACSL4) specifically in ChAT-positive motor neurons, whereas glutathione peroxidase 4 (GPX4) expression remained relatively preserved. Edaravone treatment significantly improved neurological outcomes and survival, attenuated lipid peroxidation (evidenced by decreased malondialdehyde and preserved glutathione levels), and effectively suppressed ACSL4 upregulation in the motor neurons. Furthermore, edaravone mitigated neuroinflammation by reducing astrogliosis and microglial activation. These findings provide the first evidence that ACSL4-mediated ferroptosis is a key driver of acute spinal motor neuron injury following CA. Edaravone exerts potent neuroprotection by targeting this pathway, suggesting its therapeutic potential for ameliorating spinal cord injury in patients with CA.\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: 42517904\nTitle: Bioactive adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres promotes spinal cord repair by suppressing inflammation, apoptosis, oxidative stress, and ferroptosis.\nAbstract: Spinal cord injury (SCI) is a devastating neurological condition characterized by severe neuronal loss, inflammation, oxidative stress, and various forms of regulated cell death that collectively impair functional recovery. The present study aimed to develop a bioactive therapeutic platform based on an adipose-derived extracellular matrix (ECM) hydrogel incorporating cytokine-releasing PLGA microspheres to promote spinal cord repair. The hydrogel was fabricated from decellularized adipose tissue and combined with microspheres encapsulating interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and glial cell line-derived neurotrophic factor (GDNF) to achieve sustained cytokine delivery. Seventy-five male Sprague-Dawley rats were randomly allocated into five experimental groups, including control, SCI, hydrogel, microsphere, and Hydrogel\u2009+\u2009Mic groups. Tissue specimens were subsequently harvested from the lesion site for further analyses. In a rat model of SCI, treatment with the cytokine-releasing microsphere-loaded hydrogel significantly improved electrophysiological conduction and locomotor recovery compared with untreated SCI animals and groups receiving individual treatments. Molecular analyses demonstrated that the combined treatment markedly suppressed the expression of pro-inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Additionally, apoptosis-related markers showed substantial modulation, characterized by decreased Caspase-3 and Bax expression and increased Bcl-2 levels. The therapy also improved the oxidative balance by increasing antioxidant markers including GSH, SOD, and CAT while reducing the lipid peroxidation marker MDA. Furthermore, ferroptosis-associated biomarkers were significantly regulated, with elevated levels of GSH, GPX4, and SLC7A11 and reduced ACSL4 expression. Histological analyses revealed significant preservation of spinal cord architecture, reduced cavity formation, enhanced neuronal survival, and decreased glial activation in animals treated with the composite hydrogel system. Collectively, these findings demonstrate that adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres provides a multifunctional therapeutic strategy that attenuates inflammation, apoptosis, oxidative stress, and ferroptosis, ultimately promoting structural and functional recovery following spinal cord injury.\n\nID: 42510583\nTitle: Omega-3 Fatty Acids Attenuate Neuropathic Pain by Modulating Ferroptotic Stress, Selenoamino Acid Metabolism, and Lipid Remodeling.\nAbstract: Neuropathic pain (NP) arises from diverse conditions, including peripheral nerve injury, spinal cord injury (SCI), and painful diabetic neuropathy, yet these disorders share oxidative stress, mitochondrial dysfunction, lipid dysregulation, and altered neuronal excitability. We investigated whether dietary omega-3 polyunsaturated fatty acids modulate ferroptotic stress-associated pathways, defined as lipid peroxidation susceptibility and impaired antioxidant defense rather than overt ferroptotic cell death. Female Sprague-Dawley rats received either a soy oil control diet (SOD) or fish oil omega-3-enriched diet (FOD) before chronic constriction injury (CCI). Behavioral outcomes were assessed using Hargreaves and CatWalk testing, followed by dorsal root ganglion (DRG) RNA sequencing, RT-PCR, and GPX4 ELISA. Previously generated SCI metabolomics and human diabetic serum metabolomic/lipidomic datasets were re-analyzed for shared pathways. FOD attenuated CCI-induced thermal hypersensitivity and improved gait parameters. DRG transcriptomics showed reduced injury-associated transcriptional disruption, enrichment of selenoamino acid metabolism, nonsense-mediated decay, and ribosomal quality-control pathways, and reduced mitochondrial dysfunction pathway activity. Omega-3 increased Gpx1/Gpx4 expression and GPX4 protein, reduced pain-associated genes including Scn10a, Piezo2, Trpa1, and Oprm1, and aligned with selenoamino acid enrichment in SCI and human datasets. Human lipidomics showed MG/DG/PC/PE pathway remodeling. These findings support ferroptotic stress as a plausible shared downstream mechanism modulated by omega-3 supplementation across NP models.\n\nID: 42499235\nTitle: Multiomics Profiling Identifies Tlr4 as a Therapeutic Target of Necroptosis in Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) leads to a complex cascade of cellular events, among which necroptosis plays a critical role in exacerbating neuronal injury and inflammation. In this study, we aimed to identify and validate key genes associated with necroptosis in SCI using bulk RNA-seq data, followed by differential analysis and weighted gene coexpression network analysis (WGCNA). We identified several candidate necroptosis-related genes, and further least absolute shrinkage and selection operator (LASSO) regression highlighted five SCI-necroptosis differentially expressed genes (DEGs): toll-like receptor 4 (Tlr4), Nlrp3, Il1b, Tnfaip3, and Stat4. These genes were validated using RT-qPCR and western blot experiments. Our analysis revealed that necroptosis scores were significantly elevated following SCI. Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) analysis revealed that Tlr4 was upregulated in myeloid cells (microglia and macrophages) and played a pivotal role in triggering downstream necroptosis, which was confirmed by protein levels. In vitro and in vivo experiments confirmed that Tlr4 inhibition attenuated necroptosis and inflammation. This study is the first to establish Tlr4 as a direct upstream regulator of the pRIPK1/pRIPK3/pMLKL necroptotic axis in SCI, distinct from its role as a general inflammatory mediator, suggesting Tlr4 as a promising therapeutic target for functional recovery.\n\nID: 42486345\nTitle: Novel role of GADD45A in synergistic regulation of neuronal ferroptosis and apoptosis after spinal cord injury via NF-\u03baB signaling.\nAbstract: Ferroptosis and apoptosis are major mechanisms of neuronal injury after spinal cord injury (SCI), but regulators that coordinate both processes remain poorly defined. In this study, we analyzed 188 ferroptosis-related differentially expressed genes (FRDEGs) at 7\u00a0day (7d) after SCI and identified GADD45A as a central gene in the post-SCI ferroptosis network, with a functional profile closely linked to apoptosis. GADD45A was markedly upregulated in injured spinal cord tissue. In vivo, GADD45A knockdown improved neurological recovery and promoted tissue repair by modulating markers of ferroptosis and apoptosis. In H2O2-treated PC12 cells, GADD45A knockdown reduced the expression of Cleaved Caspase-3, BAX, Cleaved Caspase-9, 4-HNE, and ACSL4, while increasing the expression of BCL-2, GPX4, FTH1, and FPN. It also attenuated H2O2-induced cellular injury. Mechanistically, GADD45A knockdown inhibited NF-\u03baB signaling and reduced nuclear translocation of NF-\u03baB-p65. These protective effects were reversed by the NF-\u03baB activator CU-T12-9. Collectively, these findings suggest that GADD45A promotes neuronal ferroptosis and apoptosis after SCI by regulating the NF-\u03baB pathway, and that GADD45A may be a potential therapeutic target for SCI.\n\nID: 42464547\nTitle: [Mechanisms of Piezo1-mediated microglial ferroptosis in inhibiting spinal cord injury repair].\nAbstract: To investigate the mechanism of the mechanosensitive ion channel Piezo1 in microglial ferroptosis following spinal cord injury (SCI), and to assess the effects of Piezo1 inhibition on ameliorating the injury microenvironment and promoting neurological functional recovery. Primary microglia cells were extracted from neonatal 1-2 days C57BL/6 mice and divided into control group, Yoda1 (Piezo1 agonist) group, and Yoda1+GsMTx4 (Piezo1 inhibitor) group. Live/dead cell staining, reactive oxygen species (ROS) fluorescence staining, 5, 5', 6, 6'-tetrachloro-1, 1', 3, 3'-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) mitochondrial membrane potential detection, and transmission electron microscopy were utilized to assess microglial ferroptosis and mitochondrial functional characteristics. SPF female C57BL/6 mice aged 6 to 8 weeks were used to detect the expression of Piezo1 at different time points after SCI by Western blot, and the two time points with no significant change and the most significant change in Piezo1 expression after SCI were selected for subsequent experiments. T 8, T 9 SCI models were established by modified Allen's method, and were divided into sham operation group, injury group, and injury+shPiezo1 group (Piezo1-targeted interfering virus AAV-shPiezo1 was injected in situ to knock down the expression of Piezo1 14 days before modeling). Colocalization of Piezo1 with microglial markers purinergic receptor P2Y12 (P2ry12), and the expressions of glutathione peroxidase 4 (GPX4) and acyl coenzyme A synthetase long chain member 4 (ACSL4) were observed by immunofluorescence staining. Basso Mouse Scale (BMS) score was used to assess hindlimb motor function in mice. The level of ROS was detected by dihydroethidium (DHE) staining; the content of malondialdehyde (MDA) was detected by MDA kit; the levels of tumor necrosis factor \u03b1 (TNF-\u03b1) and interleukin 10 (IL-10) were detected by ELISA assay; the pathological morphology of spinal cord was observed by HE staining. In vitro experiments showed that compared with the control group, the Yoda1 group had typical ultrastructural changes of ferroptosis, such as increased microglial cell death, enhanced ROS fluorescence, mitochondrial membrane potential depolarization, mitochondrial shrinkage and mitochondrial cristae breakage (all P<0.05), while the GsMTx4 group could partially reverse the above effects ( P<0.05). In vivo experiments demonstrated that the expression of Piezo1 in spinal cord tissue was up-regulated sequentially after SCI, and reached the peak on the 7th day after SCI ( P<0.05), and it was mainly localized in P2ry12-positive microglia. Compared with the injury group, in the injury+shPiezo1 group, the expression of ferroptosis core protein GPX4 in microglia was increased, the expression of ACSL4 was decreased, the levels of ROS and MDA in spinal cord tissue were decreased ( P<0.05), the level of pro-inflammatory factor TNF-\u03b1 was decreased, and the level of anti-inflammatory factor IL-10 was increased ( P<0.05). In addition, the BMS score was significantly higher than that of the injury group ( P<0.05) from the 14th day after operation, and the spinal cord tissue structure was relatively well preserved, and the cavity area was reduced. SCI activates the Piezo1 channel in microglia, triggering mitochondrial dysfunction and mediating cellular ferroptosis, thereby aggravating secondary neuroinflammation. Targeted inhibition of Piezo1 effectively blocks the ferroptosis process, ameliorates the immune microenvironment, and promotes tissue repair and locomotor functional recovery after SCI. \u63a2\u7a76\u673a\u68b0\u654f\u611f\u6027\u79bb\u5b50\u901a\u9053Piezo1\u5728\u810a\u9ad3\u635f\u4f24\uff08spinal cord injury\uff0cSCI\uff09\u540e\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u4e2d\u7684\u4f5c\u7528\u673a\u5236\uff0c\u5e76\u8bc4\u4f30\u6291\u5236Piezo1\u5bf9\u6539\u5584\u635f\u4f24\u5fae\u73af\u5883\u53ca\u4fc3\u8fdb\u795e\u7ecf\u529f\u80fd\u6062\u590d\u7684\u5f71\u54cd\u3002. \u63d0\u53d6\u65b0\u751f1\uff5e2 d C57BL/6\u5c0f\u9f20\u539f\u4ee3\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001Yoda1\uff08Piezo1\u6fc0\u52a8\u5242\uff09\u7ec4\u53caYoda1+GsMTx4\uff08Piezo1\u6291\u5236\u5242\uff09\u7ec4\u3002\u5229\u7528\u6d3b\u6b7b\u7ec6\u80de\u67d3\u8272\u3001\u6d3b\u6027\u6c27\uff08reactive oxygen species\uff0cROS\uff09\u8367\u5149\u67d3\u8272\u30015\uff0c5\u2019\uff0c6\uff0c6\u2019-\u56db\u6c2f-1\uff0c1\u2019\uff0c3\uff0c3\u2019-\u56db\u4e59\u57fa\u82ef\u5e76\u54aa\u5511\u78b3\u82b1\u9752\u7898\u5316\u7269\uff085\uff0c5\u2019\uff0c6\uff0c6\u2019-tetrachloro-1\uff0c1\u2019\uff0c3\uff0c3\u2019-tetraethylbenzimidazolylcarbocyanine iodide\uff0cJC-1\uff09\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u68c0\u6d4b\u53ca\u900f\u5c04\u7535\u955c\u89c2\u5bdf\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u53ca\u7ebf\u7c92\u4f53\u529f\u80fd\u7279\u5f81\u3002\u53d66\uff5e8\u5468\u9f84SPF\u7ea7\u96cc\u6027C57BL/6\u5c0f\u9f20\uff0c\u91c7\u7528Western blot\u68c0\u6d4bPiezo1\u5728SCI\u540e\u4e0d\u540c\u65f6\u95f4\u70b9\u7684\u8868\u8fbe\u89c4\u5f8b\uff0c\u9009\u53d6\u635f\u4f24\u540ePiezo1\u8868\u8fbe\u672a\u89c1\u660e\u663e\u6539\u53d8\u53ca\u53d8\u5316\u6700\u663e\u8457\u76842\u4e2a\u65f6\u95f4\u70b9\u8fdb\u884c\u540e\u7eed\u5b9e\u9a8c\u3002\u91c7\u7528\u6539\u826fAllen\u6cd5\u5236\u5907T 8\u3001T 9 SCI\u6a21\u578b\uff1b\u5b9e\u9a8c\u5206\u4e3a\u5047\u624b\u672f\u7ec4\u3001\u635f\u4f24\u7ec4\u548c\u635f\u4f24+shPiezo1\u7ec4\uff08\u9020\u6a21\u524d14 d\u539f\u4f4d\u6ce8\u5c04\u9776\u5411Piezo1\u7684\u5e72\u6270\u75c5\u6bd2AAV-shPiezo1\u4ee5\u6572\u4f4ePiezo1\u8868\u8fbe\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u89c2\u5bdfPiezo1\u4e0e\u5c0f\u80f6\u8d28\u7ec6\u80de\u6807\u5fd7\u7269\u560c\u5464\u80fd\u53d7\u4f53P2Y12\uff08purinergic receptor P2Y12\uff0cP2ry12\uff09\u7684\u5171\u5b9a\u4f4d\u53ca\u8c37\u80f1\u7518\u80bd\u8fc7\u6c27\u5316\u7269\u91764\uff08glutathione peroxidase 4\uff0cGPX4\uff09\u3001\u9170\u57fa\u8f85\u9176A\u5408\u6210\u9176\u957f\u94fe\u5bb6\u65cf\u6210\u54584\uff08acyl coenzyme A synthetase long chain member 4\uff0cACSL4\uff09\u7684\u8868\u8fbe\uff1bBasso Mouse Scale\uff08BMS\uff09\u8bc4\u5206\u8bc4\u4f30\u5c0f\u9f20\u540e\u80a2\u8fd0\u52a8\u529f\u80fd\uff1b\u4e8c\u6c22\u4e59\u952d\uff08dihydroethidium\uff0cDHE\uff09\u67d3\u8272\u68c0\u6d4b\u7ec4\u7ec7ROS\u6c34\u5e73\uff1b\u4e19\u4e8c\u919b\uff08malondialdehyde\uff0cMDA\uff09\u8bd5\u5242\u76d2\u68c0\u6d4bMDA\u542b\u91cf\uff1bELISA\u68c0\u6d4b\u708e\u75c7\u56e0\u5b50TNF-\u03b1\u3001IL-10\u6c34\u5e73\uff1bHE\u67d3\u8272\u89c2\u5bdf\u810a\u9ad3\u7ec4\u7ec7\u75c5\u7406\u5f62\u6001\u3002. \u4f53\u5916\u5b9e\u9a8c\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cYoda1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u6b7b\u4ea1\u589e\u591a\u3001ROS\u8367\u5149\u589e\u5f3a\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u53bb\u6781\u5316\u3001\u7ebf\u7c92\u4f53\u51fa\u73b0\u76b1\u7f29\u53ca\u5d74\u65ad\u88c2\u7b49\u94c1\u6b7b\u4ea1\u5178\u578b\u8d85\u5fae\u7ed3\u6784\u6539\u53d8\uff08\u5747 P<0.05\uff09\uff1b\u800cGsMTx4\u7ec4\u53ef\u90e8\u5206\u9006\u8f6c\u4e0a\u8ff0\u6548\u5e94\uff08 P<0.05\uff09\u3002\u4f53\u5185\u5b9e\u9a8c\u793a\uff0cSCI\u540e\u810a\u9ad3\u7ec4\u7ec7\u4e2dPiezo1\u8868\u8fbe\u5448\u65f6\u5e8f\u6027\u4e0a\u8c03\uff0c\u672f\u540e7 d\u8fbe\u5cf0\u503c\uff08 P<0.05\uff09\uff0c\u4e14\u4e3b\u8981\u5b9a\u4f4d\u4e8eP2ry12\u9633\u6027\u5c0f\u80f6\u8d28\u7ec6\u80de\u3002\u4e0e\u635f\u4f24\u7ec4\u6bd4\u8f83\uff0c\u635f\u4f24+shPiezo1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u5185\u94c1\u6b7b\u4ea1\u6838\u5fc3\u86cb\u767dGPX4\u8868\u8fbe\u56de\u5347\u3001ACSL4\u8868\u8fbe\u4e0b\u964d\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5185ROS\u53caMDA\u6c34\u5e73\u964d\u4f4e\uff08 P<0.05\uff09\uff0c\u540c\u65f6\u4fc3\u708e\u56e0\u5b50TNF-\u03b1\u6c34\u5e73\u4e0b\u964d\u3001\u6297\u708e\u56e0\u5b50IL-10\u6c34\u5e73\u5347\u9ad8\uff08 P<0.05\uff09\uff1b\u6b64\u5916\uff0c\u81ea\u672f\u540e14 d\u8d77BMS\u8bc4\u5206\u663e\u8457\u9ad8\u4e8e\u635f\u4f24\u7ec4\uff08 P<0.05\uff09\uff0c\u4e14\u810a\u9ad3\u7ec4\u7ec7\u7ed3\u6784\u4fdd\u5b58\u76f8\u5bf9\u5b8c\u597d\uff0c\u7a7a\u6d1e\u9762\u79ef\u51cf\u5c0f\u3002.

We investigated the role of sphingosine-1-phosphate receptor 2 (S1P2 receptor) in contusive spinal cord injury and evaluated the therapeutic effects of an S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) in a rat model of SCI. The SCI model was established using a 10\u2009g weight dropped onto the T10 vertebrae in female rats. After functional testing, spinal cords were harvested for biochemical and histopathological assays at different time points. Nissl and Prussian blue staining were used to analyse neuronal death. Neuronal ferroptosis in spinal cords was examined using transmission electron microscopy, and lipid peroxidation in the cultured neurones was analysed. After SCI, S1P (Sphingosine 1-phosphate) was released from crushed spinal cords and subsequently activated the neuronal S1P2 receptor to increase lipid peroxidation, which injured neurones via inducing neuronal ferroptosis through the P-ERK/ERK/ACSL4 pathway, resulting in limb paralysis. S1P2 receptor inhibition significantly blocked S1P2 receptor activation and attenuated neuronal ferroptosis. Thus, S1P2 receptor was a therapeutic target for the treatment of SCI. Systemic administration of the S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) effectively promoted locomotor function recovery by attenuating neuronal ferroptosis in rat spinal cords. S118 impeded neuronal ferroptosis by inhibiting lipid peroxidation. Contusive SCI is characterised by neuronal loss due to S1P2 receptor activation in spinal neurones. S1P2 receptor activation increases lipid peroxidation, which induces neuronal ferroptosis. S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) improves locomotor functional recovery by preserving the spinal cord structure after SCI.\n\nID: 42381706\nTitle: Pyroptosis as a novel therapeutic target in glioblastoma multiforme: Mechanisms, molecular insights, and therapeutic potential.\nAbstract: Glioblastoma multiforme (GBM) is the most malignant type of primary brain tumor. Its clinical management is challenging due to its heterogeneity, highly malignant nature, and insensitivity to standard treatments. While current strategies for GBM treatments are based on inducing apoptosis in GBM cells, some GBM tumors showed resistance to this type of cell death. Recent evidence indicates that pyroptosis is a novel, promising therapeutic method for overcoming tumor cells' resistance to cancer treatment. This inflammatory programmed cell death type is mediated by the cleavage of gasdermin proteins. Based on the evidence, inducing pyroptosis is negatively associated with GBM growth and development; the exact molecular mechanisms and the signaling pathways underlying pyroptosis are not fully understood. This review presents the different pathways of pyroptosis and its role in GBM growth regulating and illustrates various drugs and components that modulate pyroptosis in GBM tumors. It also investigates the regulatory roles of noncoding RNAs in pyroptosis modulation in GBM tumors, providing promising therapeutic approaches that target pyroptosis as a novel strategy for GBM treatment.\n\nID: 42349221\nTitle: Corrigendum to \"Salvigenin mitigates neuronal ferroptosis by binding to PI3K and enhancing the interaction between VCP and PI3K in the repair of spinal cord injury\" [Phytomedicine, Volume 147, 2025, 157181].\nAbstract: \n\nID: 42337999\nTitle: Anti-HMGB1 Antibody Therapy Ameliorates Depression Following Spinal Cord Injury in Rats by Inhibiting Ferroptosis.\nAbstract: Depression following spinal cord injury (D-SCI) refers to a depressive state that occurs in an individual after a major spinal cord injury (SCI), characterized mainly by low mood and reduced interest. This study aims to investigate the regulatory role of anti-HMGB1 antibody in the depressive-like behaviour of D-SCI rats and to explore its underlying mechanisms. A depression model was established in rats 5\u2009weeks after SCI. The expression of HMGB1 and ferroptosis markers (MDA, GSH and iron ion deposition) in the hippocampus were examined in both the sham group and the D-SCI group. Subsequently, D-SCI rats were treated with an anti-HMGB1 antibody, and the depression-like behaviours of each group were assessed using open field and sucrose preference tests. Ferroptosis levels in the hippocampus, as well as the expression of ferroptosis-related proteins (ACSL4, SLC7A11 and GPX4), were also investigated. The co-localization of HMGB1 and NeuN in the rat hippocampus was detected by immunofluorescence double staining. Furthermore, at the cellular level, the effect of the anti-HMGB1 antibody on Erastin-induced ferroptosis in rat hippocampal neurons was analysed. The results indicated that compared to the sham group, the levels of HMGB1 and ferroptosis in the hippocampus of rats in the D-SCI group were significantly elevated. Administering anti-HMGB1 antibody to D-SCI rats could significantly augment their activity distance, movement speed and sucrose preference rate, while also suppressing the ferroptosis level and the expression of ferroptosis-related proteins in the hippocampus. Moreover, HMGB1 and NeuN were co-expressed in the rat hippocampus. The results from primary rat hippocampal neurons indicated that anti-HMGB1 antibody could inhibit erastin-induced ferroptosis in rat hippocampal neurons. Taken together, anti-HMGB1 antibody therapy can ameliorate depressive behaviour in D-SCI rats; the possible mechanism may involve the inhibition of ferroptosis in hippocampal neurons.\n\nID: 42327731\nTitle: Endothelial ferroptosis in blood-brain barrier dysfunction and neuroinflammation: mechanisms and immune-vascular crosstalk.\nAbstract: Ferroptosis is an iron-dependent form of regulated cell death driven by phospholipid peroxidation. In the central nervous system (CNS), most ferroptosis research has focused on neurons and glial cells, whereas the vulnerability of brain microvascular endothelial cells (BMECs) and its consequences for blood-brain barrier (BBB) integrity remain less clearly defined. Because BMECs form the vascular interface between the circulation and the brain parenchyma, ferroptotic injury in this cell population may represent an immunovascular mechanism through which endothelial redox stress is translated into barrier dysfunction and neuroinflammatory amplification. In this review, we summarize molecular pathways that may promote or restrain BMEC ferroptosis, including iron handling, antioxidant defense mediated by the solute carrier family 7 member 11 (SLC7A11)-glutathione peroxidase 4 (GPX4) axis and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, lipid peroxidation, and junctional remodeling. We then discuss how ferroptosis-associated endothelial injury may contribute to BBB leakage, damage-associated molecular pattern release, innate immune sensing, leukocyte recruitment, glial activation, and self-amplifying inflammatory feedback at the neurovascular interface. We organize the available literature according to the strength and cellular specificity of evidence, separating BMEC-specific findings, BBB-focused in vivo studies, indirect CNS evidence, and mechanistic analogies from non-CNS endothelial systems. Finally, we evaluate disease-specific evidence in ischemic stroke and selected neurodegenerative or inflammatory conditions, together with therapeutic strategies, BMEC-targeting considerations, candidate clinical biomarkers, and translational barriers for modulating endothelial ferroptosis. This review frames endothelial ferroptosis as a promising but incompletely established immunovascular link between BBB dysfunction and neuroinflammation, and highlights the need for BMEC-specific models, human BBB systems, endothelial ferroptosis biomarkers, biomarker-guided monitoring, BMEC-targeted delivery approaches, and careful evaluation of the physiological risks of systemic or prolonged ferroptosis blockade.\n\nID: 42320701\nTitle: miR-10a-5p Attenuates spinal cord ischemia/reperfusion injury by targeting transforming growth factor beta-activated kinase 1 to suppress Acyl-CoA synthetase long-chain family member 4-mediated ferroptosis in male rats.\nAbstract: Spinal cord ischemia/reperfusion (I/R) injury is a severe complication following thoracoabdominal aortic surgeries, often leading to paraplegia. Ferroptosis, an iron-dependent form of regulated cell death, contributes significantly to this pathology. This study investigates the hypothesis that miR-10a-5p attenuates spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. A spinal cord I/R injury model was established in male Sprague-Dawley male rats via transient aortic occlusion. Intrathecal injections of the ferroptosis inhibitor Liproxstatin-1 (Lip-1), siRNA targeting ACSL4 or TAK1, and miR-10a-5p agomir/antagomir were administered prior to ischemia induction. Neurological function was assessed using Tarlov scores. Histopathological changes were evaluated by H&E, Nissl, and immunofluorescence staining. Mitochondrial ultrastructure was examined by transmission electron microscopy (TEM). Expression levels of ferroptosis-related markers (ACSL4, GPX4, COX2, FTH1), inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and lipid peroxidation products (MDA, 12-HETE, 15-HETE, LPO) were measured using Western blot, qPCR, and ELISA. The targeting relationship between miR-10a-5p and TAK1 was validated by dual-luciferase reporter assay. Spinal cord I/R injury induced significant neurological deficits, ferroptosis (evidenced by increased iron, MDA, ACSL4, and COX2; decreased GPX4 and GSH), lipid peroxidation, and inflammation. Lip-1 treatment ameliorated these changes. Knockdown of ACSL4 or TAK1 similarly inhibited ferroptosis, reduced inflammation, and improved motor function. Spinal cord I/R injury induced significant downregulation of miR-10a-5p. It directly targeted TAK1, as confirmed by luciferase assay. Consequently, miR-10a-5p overexpression suppressed TAK1/ACSL4 axis, mitigated lipid peroxidation and ferroptosis, and reduced pro-inflammatory cytokine levels (TNF-\u03b1 and IL-1\u03b2), leading to improved neurological outcomes. This study demonstrates that miR-10a-5p plays a protective role in spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. These findings highlight the potential of the miR-10a-5p/TAK1/ACSL4 axis as a novel therapeutic target for preventing and treating spinal cord I/R injury.\n\nID: 42317798\nTitle: LXR\u03b1/SCD1-Mediated Endoplasmic Reticulum-Mitochondria Crosstalk in Inhibiting Neuronal Ferroptosis after Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) causes extensive neuronal loss, in which ferroptosis is critically involved. Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma.\n\nID: 42313317\nTitle: Mechanisms ofra Tetmethylpyrazine in spinal cord injury: a narrative review.\nAbstract: Spinal cord injury (SCI) is characterized by irreversible loss of motor and sensory function, imposing a substantial burden on patients and their families. Tetramethylpyrazine (TMP), a bioactive compound derived from traditional Chinese medicine, possesses a wide range of pharmacological activities and has demonstrated potential therapeutic effects in the treatment of SCI. Therefore, this article provides a comprehensive review of the mechanisms by which TMP promotes spinal cord repair. This review compiles a large body of in vitro, in vivo, and clinical studies, including a total of 86 publications documenting the effects of TMP on SCI. The results indicate that the mechanisms by which TMP exerts its effects in SCI treatment include promoting nerve regeneration, improving vascular dysfunction, exerting anti-inflammatory effects, inhibiting neuronal apoptosis, reducing oxidative stress, regulating iron metabolism, maintaining ion homeostasis, alleviating pyroptosis, and modulating autophagy. Through these mechanisms, TMP contributes to the restoration of spinal cord morphology, motor function, and electrophysiological parameters in experimental animal models. Clinical reports on the use of TMP injection for SCI are relatively limited, and its clinical efficacy requires further investigation. The combined application of nanotechnology or hydrogels provides an efficient targeted delivery and sustained-release system for TMP in the spinal cord, thereby significantly enhancing its bioavailability. Overall, TMP shows promising potential in SCI treatment and may serve as a valuable adjunctive therapeutic strategy.\n\nID: 42313207\nTitle: STAT3 Signaling in Spinal Cord Injury: Neurochemical Mechanisms Linking Neuroinflammation, Mitochondrial Stress, and Glial Remodeling.\nAbstract: Spinal cord injury (SCI) is a devastating neurological disorder marked by profound disturbances in cytokine signaling, redox balance, mitochondrial homeostasis, and glial-neuronal communication. Although many therapeutic strategies have been explored to attenuate secondary injury, effective molecularly targeted interventions remain limited. Increasing evidence identifies signal transducer and activator of transcription 3 (STAT3) as a central signaling node in the neurochemical response to SCI. Recent studies indicate that STAT3 exhibits pronounced spatiotemporal and cell-type-specific activation after SCI. Depending on the upstream trigger and cellular compartment involved, STAT3 can amplify or restrain neuroinflammation, shape astrocyte and microglial reactivity, influence mitochondrial bioenergetics and oxidative stress, modulate ferroptosis and apoptosis, and alter the regenerative state of the injured spinal cord. In this review, we frame STAT3 not simply as a downstream effector of the JAK/STAT cascade, but as an integrative regulator of SCI neurochemistry that links cytokine-driven signaling to metabolic stress, glial remodeling, and axonal repair. We emphasize how injury phase, cell type, and subcellular localization influence STAT3-dependent outcomes, discuss emerging therapeutic strategies that converge on STAT3-centered pathways, and outline the key challenges that must be addressed for precise translational targeting.\n\nID: 42302937\nTitle: Chinese herbal and natural compounds for Parkinson's disease: Myth or truth.\nAbstract: Parkinson's disease is a common neurodegenerative disorder with a complex pathogenesis, which limits the application of single-target inhibitors. At present, the main Western therapeutic drugs for Parkinson's disease include dopamine precursors, dopamine receptor agonists, monoamine oxidase inhibitors (MAO-B), catechol-O-methyltransferase (COMT) inhibitors and anticholinergic drugs. These treatments have limited efficacy and obvious toxic and side effects. In recent years, with the deepening of research on Parkinson's disease, traditional Chinese medicine (TCM) and its active components have played an increasingly important role in clinical treatment. A large number of studies have shown that TCM and its active components exert anti-Parkinsonian effects by inhibiting ferroptosis, regulating autophagy and apoptosis, exerting anti-inflammatory and antioxidant effects, and enhancing neuronal protection. To show that traditional medicine is a promising strategy for the treatment of Parkinson's disease, and to lay a foundation for exploring the specific mechanisms of traditional Chinese medicine in the prevention and treatment of this disease. This study conducted a bibliometric analysis of Chinese and foreign databases to screen the core traditional Chinese medicines currently used clinically for Parkinson's disease, and further analyzed the specific mechanisms of action of the selected core herbs in the treatment of Parkinson's disease. Bibliometric analysis identified core TCM herbs clinically used for Parkinson's disease. The specific mechanisms of these core herbs against Parkinson's disease were clarified at the molecular level, involving inhibition of ferroptosis, regulation of autophagy and apoptosis, anti-inflammatory and antioxidant effects, and enhancement of neuroprotection. This study provides data support for the subsequent research and clinical application of traditional Chinese medicine in Parkinson's disease, and deepens the molecular understanding of the efficacy of traditional Chinese medicine, verifying that traditional medicine is a promising therapeutic strategy for Parkinson's disease.\n\nID: 42297112\nTitle: Astrocyte-derived exosome-mediated siRNA delivery combined with quercetin-Mn complex promotes neural repair in spinal cord injury.\nAbstract: Neuroinflammation and oxidative stress are pivotal drivers of neurological dysfunction following spinal cord injury (SCI). Consequently, precise modulation of pathological glial cells and amelioration of the neuronal microenvironment represent a promising therapeutic strategy. Herein, we developed an injectable, self-healing hydrogel system composed of oxidized sodium alginate, carboxymethyl chitosan, and tannic acid (OCT) for the sustained co-delivery of a Quercetin-Manganese complex (QM) and astrocyte-derived extracellular vesicles encapsulating siRNA (AEVs@siRNA). RNA sequencing revealed significant enrichment of the TNF and chemokine signaling pathways in SCI mice, with a notable upregulation of Serpina3n. This gene, predominantly expressed in astrocytes, modulates their reactive polarization. Leveraging the innate tropism of astrocyte-derived extracellular vesicles, we achieved targeted delivery of Serpina3n-targeting siRNA to astrocytes at the lesion site. This approach effectively suppressed the expression of Serpina3n, inhibiting the transition to a neurotoxic A1 phenotype and alleviating neuronal damage. Concurrently, the sustained release of QM NPs potently scavenged reactive oxygen species, significantly mitigating neuronal ferroptosis. Further mechanistic investigations demonstrated that this combinatorial system attenuated neuroinflammation by inhibiting NF-\u03baB p65 signaling to reduce A1 astrocyte activation, and protected neurons by regulating the SLC7A11/GPX4 axis to counteract apoptosis and ferroptosis, both in vitro and in vivo. Consequently, this targeted delivery system represents a promising approach for enhancing therapeutic efficacy and promoting neural repair following SCI.\n\nID: 42292377\nTitle: Digging deeper into NINJ1: its multifaceted role in central nervous system diseases.\nAbstract: Ninjurin1 (NINJ1) is a cell-surface molecule that has gained considerable attention for its role in mediating plasma membrane rupture (PMR). Originally identified as an adhesion molecule induced after nerve injury, NINJ1 is now recognized as a common terminal executor of PMR across multiple forms of lytic cell death, including pyroptosis, necroptosis, and ferroptosis. This function positions NINJ1 as a key link between cell death and inflammatory activation. However, the precise role of NINJ1 in the central nervous system (CNS) remains unclear. This review systematically outlines the molecular structure, expression, activation, and regulation of NINJ1, with a focus on its multifaceted roles in CNS disorders, including multiple sclerosis, ischemic stroke, traumatic brain injury, spinal cord injury, neuropsychiatric disorders and neurodegenerative diseases. We also highlight critical knowledge gaps, particularly regarding cell type-specific functions in the CNS. Finally, we evaluate therapeutic strategies targeting NINJ1 (including monoclonal antibodies, functional peptides, and small-molecule inhibitors)\u00a0and their potential applications in neurological diseases. By integrating current evidence and identifying unresolved questions, this review aims to provide a foundation for future mechanistic and translational studies of NINJ1 in the CNS.\n\nID: 42289170\nTitle: Mitochondrial homeostasis imbalance-triggered PANoptosis in traumatic brain and spinal cord injury: from mechanism to therapeutic strategies.\nAbstract: Traumatic injury to the central nervous system (CNS), also known as traumatic brain injury (TBI) and spinal cord injury (SCI), is characterized by high disability and mortality worldwide. PANoptosis is a newly identified cell death mode that synergistically initiates pyroptosis, apoptosis and necroptosis via activation of PANoptosome. It is closely associated with oxidative stress, neuroinflammation, and secondary injury following TBI and SCI, yet the key pathogenic factors and mechanisms underlying PANoptosis remain incompletely elucidated. Mitochondria, as a central organelle for energy synthesis and oxidative stress, its health and homeostasis are the cornerstone of cell survival and biological function. Emerging evidence suggests that the loss of mitochondrial homeostasis plays a fundamental role in the activation and execution of PANoptosis across various cell types. Here, we review the detailed manifestations of mitochondrial homeostasis imbalance in TBI and SCI, such as impaired biogenesis, abnormal dynamics, mitophagy dysfunction, and mitochondria-derived vesicles. Meanwhile, we systematically analyze the characteristics and pathological effects of PANoptosis cascade following TBI and SCI, with a focus on the regulatory patterns, mechanisms, and potential targets of injured mitochondria driving PANoptosis. In addition, we discuss the advancements and future perspectives of mitochondria-based strategies for modulating PANoptosis in TBI and SCI. Taken together, despite considerable challenges in governing post-traumatic mitochondria homeostasis, its multiple targeting of the upstream PANoptosome and downstream cell death signaling offers a promising approach to improve the outcome of CNS trauma.\n\nID: 42286867\nTitle: Hydrogen Sulfide Rescues Microglia From HIV Tat-Driven Ferroptosis: Implications for HIV-Associated Neuroinflammation.\nAbstract: HIV transactivator of transcription (Tat) protein induces oxidative stress, neuroinflammation, and glial dysfunction in NeuroHIV. Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, has emerged as a contributor to HIV-associated neurocognitive disorders. This study aimed to determine whether hydrogen sulfide (H2S) mitigates HIV Tat-induced ferroptosis in microglial cells. BV2 microglial cells were pretreated with sodium hydrosulfide (NaHS; 100\u2009\u03bcM), an H2S donor, followed by exposure to recombinant HIV Tat (100\u2009ng/mL, 48\u2009h). Ferroptotic indices, including cytosolic Fe2+ accumulation, lipid peroxidation, reactive oxygen species (ROS) generation, and cell membrane damage, were assessed using fluorescence-based assays and lactate dehydrogenase (LDH) release. Expression of ferroptosis-related and antioxidant proteins was analyzed by western blotting, and proinflammatory cytokine release was quantified by qPCR. NaHS pretreatment significantly attenuated HIV Tat-induced Fe2+ accumulation, ROS generation, lipid peroxidation, and LDH release. Mechanistically, NaHS suppressed pro-ferroptotic mediators, acyl-CoA synthetase long-chain family member 4 (ACSL4) and 4-hydroxynonenal (4-HNE), while restoring solute carrier family 7-member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4) expression. NaHS also reduced HIV Tat-induced IL1\u03b2, IL6, and TNF\u03b1 secretion. These findings demonstrate that H2S protects HIV Tat-exposed microglia by suppressing ferroptosis and restoring cellular homeostasis. Collectively, these results identify H2S signaling as a promising mechanistic target for further investigation in NeuroHIV-associated neuroinflammation.\n\nID: 42276195\nTitle: Therapeutic effect and mechanism of pirfenidone in bladder fibrosis after spinal cord injury.\nAbstract: Pirfenidone (PFD), a broad-spectrum anti-fibrotic agent, shows therapeutic potential in various fibrotic diseases. However, its effect on neurogenic bladder fibrosis following spinal cord injury (SCI) and its association with ferroptosis remain unclear. This study aimed to investigate the therapeutic efficacy of PFD against bladder fibrosis after SCI and to preliminarily analyze its potential link with ferroptosis using a rat SCI model and a Transforming Growth Factor-\u03b21 (TGF-\u03b21)-induced fibrotic model in Simian Virus 40-Transformed Human Urothelial Cells (SV-HUC-1). In SCI rats, PFD treatment significantly improved urodynamic parameters, while markedly reducing collagen deposition, inflammatory infiltration, and the progression of epithelial-mesenchymal transition (EMT) in bladder tissue. In the cellular model, PFD effectively attenuated TGF-\u03b21-induced fibrotic responses. Mechanistically, network pharmacology analysis predicted that PFD could modulate the TGF-\u03b21 signaling and lipid peroxidation pathways. In vivo experiments confirmed that PFD reversed the dysregulation of key ferroptosis-related molecules, and in vitro studies demonstrated that PFD antagonized Erastin-induced ferroptosis, an effect comparable to the ferroptosis inhibitor Ferrostatin-1 (Fer-1). However, in the TGF-\u03b21-induced fibrotic model, inhibition of ferroptosis alone only partially ameliorated the fibrotic phenotype, and its effect was weaker than that of PFD. This study demonstrates that PFD can effectively alleviate bladder fibrosis after SCI, and its therapeutic effect may be associated with the ferroptosis pathway. These findings suggest that PFD likely exerts its anti-fibrotic action through multi-pathway synergy, with ferroptosis inhibition representing an important contributing pathway supported by the current data, providing a new theoretical basis for treating neurogenic bladder fibrosis.\n\nID: 42274008\nTitle: USP5-C-MAF Axis Regulates Autophagy-Dependent Neuronal Ferroptosis in Spinal Cord Injury Therapeutics.\nAbstract: Spinal cord injury (SCI) is a severe secondary injury that often results in impaired motor function, imposing a significant burden on both individuals and society. Therefore, there is an urgent need for new therapeutic targets and strategies to address this challenge. To construct a mouse model of SCI, an aneurysm clip was used in\u00a0vivo to clamp the abdominal aorta below the left renal artery in C57BL/6J mice. After 60\u2009min, the aneurysm clip was removed to restore blood flow. In\u00a0vitro, primary neuronal cells were subjected to OGD/R to mimic the conditions of SCI. Cell viability was assessed using the CCK-8 assay, and the levels of neuronal death, autophagy, and ferroptosis were determined using a combination of WB, IF, and transmission electron microscopy. IP/MS and Co-IP techniques were employed for the identification and validation of proteins interacting with USP5. Neurons exhibit significant ferroptosis in the SCI mice. USP5 is markedly upregulated in SCI neurons and mediates neural ferroptosis. In\u00a0vitro experiments demonstrate that overexpression of USP5 promotes neuronal ferroptosis, whereas knockout of USP5 significantly reduces it, with consistent results observed in\u00a0vivo. Notably, the upregulation of USP5 expression markedly increases the accumulation of autophagosomes and autophagic flux in neurons, which may represent a potential mechanism by which USP5 mediates neuronal ferroptosis. Further investigations utilizing IP/MS and Co-IP confirmed the interaction between USP5 and c-MAF. Additionally, Western blot analysis revealed that USP5, through its deubiquitinating enzyme activity, enhances c-MAF protein stability, thereby activating autophagy and subsequently promoting neuronal ferroptosis. In summary, our results indicate a close relationship between ferroptosis and SCI. USP5 regulates c-MAF expression through deubiquitination, thereby activating autophagy-dependent ferroptosis in neurons and mediating the progression of SCI. USP5 may serve as a potential therapeutic target for SCI.\n\nID: 42526049\nTitle: Subcellular Regulation of Ferroptosis: Roles of Individual Intracellular Organelles and Crosstalk.\nAbstract: Ferroptosis is an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation. Emerging evidence indicates that susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets. Mitochondria play dual roles in ferroptosis by integrating metabolic activity, redox balance, and mitochondrial quality control; thereby influencing reactive oxygen species generation and lipid peroxidation. Lysosomes regulate ferroptotic sensitivity through iron mobilization, inter-organelle iron transfer, lysosomal redox activity/lipid peroxidation, lysosomal signaling hub, and ferritinophagy. The ER contributes to ferroptosis by coordinating lipid biosynthesis, membrane polyunsaturated fatty acid composition, and unfolded protein response signaling, as well as by disrupting antioxidant defenses and iron homeostasis, especially during ER stress. Lipid droplets function as dynamic lipid reservoirs that buffer oxidizable fatty acids or, upon mobilization, supply substrates that fuel ferroptosis-associated lipid peroxidation. Here, we provide a comprehensive review of current mechanistic insights and recent advances in organelle-specific regulation and inter-organelle crosstalk during ferroptosis, highlighting emerging therapeutic opportunities and key experimental challenges. An integrated understanding of this multi-organelle regulatory network is essential for modulating ferroptosis in human diseases.\n\nID: 42525293\nTitle: Targeting autophagy in oral squamous cell carcinoma chemoresistance: molecular mechanisms, therapeutic strategies, and emerging nanotherapeutic approaches.\nAbstract: Autophagy is a lysosome-dependent recycling process that maintains cellular homeostasis and helps cells adapt to therapeutic stress. In oral squamous cell carcinoma (OSCC), dysregulated autophagy may promote chemoresistance by supporting metabolic adaptation, removing damaged cellular components, and limiting treatment-induced cell death. Its effects are nevertheless context dependent, as autophagy can also interact with apoptosis, ferroptosis, and other cytotoxic pathways. This review summarizes molecular mechanisms linking autophagy to OSCC chemoresistance, focusing on non-coding RNAs, p53/TP53, BECN1, ATG-related proteins, oncogenic signaling networks, and emerging biomolecular-condensate mechanisms. It also evaluates therapeutic strategies, including early- and late-stage autophagy inhibition, mTOR-targeted modulation, metabolic interventions, genetic approaches for mechanistic validation, ferroptosis-autophagy combinations, and nanotechnology-assisted delivery systems. Although promising effects have been reported in cell lines, drug-resistant derivatives, cancer stem cell-like populations, and xenograft models, OSCC-specific clinical evidence remains limited. Future progress will require rigorous assessment of autophagic flux, careful interpretation of related head and neck squamous cell carcinoma evidence, biomarker-guided patient stratification, and validation in clinically relevant models. Integrating autophagy biology with molecular stratification and rational combination therapy may help overcome chemoresistance in OSCC.\n\nID: 42525165\nTitle: From astrocyte cholesterol synthesis to synaptic dysfunction: mechanisms of neuron-glia lipid coupling.\nAbstract: The brain contains a large proportion of the body's cholesterol, highlighting its importance in central nervous system function. Cholesterol supports neuronal membrane structure, synapse formation, synaptic vesicle activity, receptor signaling, and myelin integrity. Because the blood-brain barrier limits the entry of peripheral lipoproteins, the brain relies mainly on local cholesterol synthesis, transport, recycling, and turnover. This review examines the mechanisms that regulate astrocyte-to-neuron cholesterol transfer and explains how defects in SREBP-dependent synthesis, ApoE lipidation, ABC transporter-mediated export, neuronal uptake, intracellular trafficking, and cholesterol turnover contribute to synaptic dysfunction and neurodegeneration. In the adult brain, astrocytes are an important source of cholesterol for neurons. Astrocytic cholesterol synthesis is regulated by sterol regulatory element-binding proteins, which control the expression of key cholesterol-biosynthetic genes. Astrocytes release cholesterol in ApoE-containing lipoprotein particles through ATP-binding cassette transporters. Neurons acquire astrocyte-derived cholesterol through LDLR/LRP1, redistribute it via NPC1/NPC2, and eliminate excess cholesterol as 24 S-hydroxycholesterol through CYP46A1. Disruption of this pathway impairs membrane organization, lipid raft signaling, synaptic function, and neuronal survival. These disturbances are associated with Alzheimer's disease, Huntington's disease, and multiple sclerosis.\n\nID: 42524582\nTitle: Licoricidin triggers reactive oxygen species-mediated PANoptosis in human hepatocellular carcinoma cells.\nAbstract: Licoricidin (LCD), a natural isoflavonoid compound extracted from Glycyrrhiza species, has been extensively demonstrated to possess diverse biological activities, including anti-inflammatory and potent anti-cancer effects. However, the precise mechanism underlying LCD action against hepatocellular carcinoma (HCC) remains unclear, particularly regarding its regulation of cell death. In this study, we comprehensively explored the effects of LCD on HCC cells in vitro and investigated its role and mechanism of action in the induction of PANoptosis. Our results reveal that LCD exhibited potent anti-HCC activities by decreasing cell viability and significantly inhibiting clonogenic survival in HCC cell lines. Our results demonstrate that LCD triggered a substantial accumulation of reactive oxygen species and induced depolarization of the mitochondrial membrane, leading to profound mitochondrial dysfunction. We further confirmed that LCD activated a comprehensive PANoptosis program by synchronously upregulating the expression of apoptotic proteins (Bax, c-CASP3, and c-PARP1), pyroptotic proteins (c-CASP 1 and c-GSDMD), and the phosphorylation of necroptotic executioners (p-MLKL and p-RIPK1). Treatment with the ROS inhibitor (NAC), apoptosis inhibitor (ZVAD), or necroptosis inhibitor (Nec-1) significantly reduced the expression of PANoptosis-related proteins in LCD-treated cells. Furthermore, molecular docking simulations and cellular thermal shift assay (CETSA) assay confirmed the direct and stable binding of LCD to PANoptosis-related proteins. In summary, we show for the first time that LCD exerts favorable anti-HCC activities via the induction of PANoptosis through a ROS-dependent mechanism and potntial direct modulation of core executive proteins. This multi-target action suggests that LCD could be a novel candidate for the management of hepatocellular carcinoma.\n\nID: 42524498\nTitle: SYNCRIP drives ferroptosis resistance and metabolic activation via SIRT1 and HK2 in glioblastoma.\nAbstract: Synaptotagmin-binding cytoplasmic RNA-interacting protein (SYNCRIP) is an RNA-binding protein (RBP) implicated in the pathogenesis of various cancers through involvement in regulating multiple cellular processes. Notably, this study identified that SYNCRIP expression is significantly elevated in glioblastoma (GBM) and is associated with poor prognosis and tumor progression. Mechanistically, SYNCRIP upregulates SIRT1 expression at both the transcriptional and post-transcriptional levels by stabilizing SIRT1 mRNA. Meanwhile, loss of SYNCRIP leads to reduced SIRT1 expression, accumulation of reactive oxygen species (ROS), and induction of ferroptosis. Notably, restoration of SIRT1 rescues cells from ferroptotic cell death, supporting the critical role of SIRT1 in SYNCRIP-mediated ferroptosis resistance. SYNCRIP also enhances hexokinase 2 (HK2) expression through transcriptional activation and internal ribosome entry site (IRES)-mediated translation, thereby promoting glycolytic activity in GBM. Furthermore, depletion of SYNCRIP results in mitochondrial dysfunction and impairs GBM cell migration and invasion by downregulating epithelial-mesenchymal transition (EMT)-associated factors. Collectively, these findings suggest that SYNCRIP is a key regulator of GBM progression by maintaining metabolic homeostasis and ferroptosis resistance, highlighting SYNCRIP as a potential therapeutic target in GBM.\n\nID: 42524318\nTitle: Photoactivated iridium(III) complexes drive pyroptosis-necroptosis synergy for multi-network photoimmunotherapy of renal cell carcinoma.\nAbstract: Recurrence and metastasis are the leading causes of mortality in renal cell carcinoma (RCC), and its intrinsic drug resistance further limits effective therapeutic options. Synergistic activation of multiple regulated cell death pathways has recently emerged as a novel approach to overcome therapeutic resistance. Here, we developed two mitochondria-targeted iridium(III) photosensitizers, Ir-MT1 and Ir-MT2, for synergistic photoimmunotherapy of RCC. Upon white-light irradiation, Ir-MT1/2 induced severe mitochondrial damage and dysfunction, leading to massive release of mitochondrial contents. Mitochondrial DNA leakage activated the cGAS-stimulator of interferon genes pathway and caspase-1-mediated pyroptosis cascade, whereas excessive Ca2+ efflux promoted RIPK1/RIPK3 phosphorylation and induced necroptosis. These death signals facilitated pore formation by gasdermin D and mixed lineage kinase domain-like protein in the plasma membrane, resulting in membrane rupture, release of damage-associated molecular patterns, and immunogenic cell death synergistically. In vivo, Ir-MT1/2 not only effectively suppressed primary tumor growth but also eliminated distant tumors through activation of anti-tumor immunity, exhibiting potent therapeutic efficacy and favorable biosafety. Overall, our work provides the evidence that a single iridium complex can simultaneously trigger pyroptosis-necroptosis synergy, overcoming intrinsic drug resistance and offering a promising strategy for multi-network systemic therapy of RCC.\n\nID: 42524207\nTitle: Arteannuin B Induces Ferroptosis in Colorectal Cancer Cells via GDF15/HMGCS1/GPX4 Axis.\nAbstract: Drug resistance in colorectal cancer (CRC) necessitates novel therapeutic strategies. This study investigated whether arteannuin B, a sesquiterpene lactone from Artemisia annua, induces ferroptosis in CRC cells and elucidated the underlying molecular mechanism. Anti-CRC effects were assessed via MTT assays and xenograft models. Proteomics identified differentially expressed proteins. Arteannuin B-induced ferroptosis was confirmed by measuring reactive oxygen species (ROS), lipid peroxidation, Fe\u00b2\u207a content, glutathione peroxidase 4 (GPX4) expression, and mitochondrial morphology. Mevalonate pathway regulation was evaluated by western blotting, dual-luciferase assay, and quantification of squalene, coenzyme Q10 (CoQ10), and cholesterol. The role of growth differentiation factor 15 (GDF15) was validated using shRNA knockdown and overexpression DLD-1 cells in vitro and in vivo. Arteannuin B showed significant anti-colorectal cancer activity both in vitro and in vivo. The proteomic analysis demonstrated that arteannuin B affected the mevalonate pathway and ferroptosis in DLD-1 cells, and strongly upregulated the expression of GDF15. Arteannuin B increased ROS, lipid peroxidation, malondialdehyde, and iron while decreasing GPX4 expression and causing mitochondrial shrinkage. Arteannuin B inhibited mevalonate pathway enzymes, particularly 3-hydroxy-3-methylglutaryl-CoA synthase 1 (HMGCS1), reducing squalene, CoQ10, and cholesterol. The knockdown of GDF15 weakened the inhibitory effect of arteannuin B on the mevalonate pathway and GPX4, and reduced the sensitivity of CRC cells to arteannuin B both in vitro and in vivo. Arteannuin B triggers ferroptosis-like cell death in CRC cells and suppresses xenograft growth, in association with inhibition of the mevalonate pathway. GDF15 contributes to arteannuin B-mediated suppression of HMGCS1 and GPX4 and to ferroptosis sensitivity.\n\nID: 42524084\nTitle: Ferroptosis regulatory networks as therapeutic sensitizers in combination therapy for hepatocellular carcinoma (Review).\nAbstract: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, and multidrug resistance remains a major barrier to effective treatment. Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. The present narrative review summarizes current evidence on ferroptosis-mediated sensitization mechanisms in combination therapy for HCC, focusing on core regulatory networks, including glutathione peroxidase 4, System Xc- and iron metabolism pathways, and their interactions with key signaling pathways, such as activating transcription factor 4/signal transducer and activator of transcription 3, p53 and Wnt/\u03b2-catenin. The current review also discusses the synergistic effects and molecular mechanisms of ferroptosis inducers combined with targeted therapy, chemotherapy and immunotherapy. Furthermore, the potential value of ferroptosis-related biomarkers for predicting treatment response and prognosis is evaluated, and unresolved mechanistic questions and barriers to clinical translation are highlighted. Finally, the present review outlines future research directions, including the development of targeted nanodelivery systems and biomarker-based clinical trials, to support more precise ferroptosis-based combination strategies for HCC.\n\nID: 42524008\nTitle: Ferroptosis contributes to quercetin-induced anti-cancer activity through blockade of LGR4/NF-\u03baB/GPX4 axis in oral squamous cell carcinoma.\nAbstract: Oral squamous cell carcinoma (OSCC) is a malignancy that faces challenges such as chemotherapy resistance and side effects. There is an urgent need for effective, low-toxicity compounds to treat OSCC. Here, we examined whether quercetin induces ferroptosis in OSCC cells and explored the potential molecular mechanisms. The role of LGR4/NF-\u03baB/GPX4 in OSCC cells (CAL27 and SCC9) was studied through gene overexpression or RNA interference. Additionally, OSCC cell lines were treated with quercetin to examine its effects and underlying mechanisms in OSCC. Quercetin dose-dependently reduced the viability of OSCC cells, while co-treatment with the ferroptosis inhibitor liproxstatin-1 significantly counteracted quercetin-induced cell death. RNA-seq analysis showed that quercetin's inhibitory effect on OSCC cells is linked to ferroptosis induction. Quercetin concentration-dependently decreased GPX4 expression in OSCC cells by suppressing the LGR4/NF-\u03baB signaling pathway. LGR4-induced ferroptosis inhibition was counteracted by either quercetin or an NF-\u03baB inhibitor. Mechanistically, LGR4 could induce upregulation of IKK\u03b2, leading to I\u03baB\u03b1 ubiquitination and degradation, which promotes NF-\u03baB activation and GPX4 transcription, ultimately inhibiting ferroptosis in OSCC cells. Our findings indicate that ferroptosis may play a role in quercetin's anti-OSCC activity by blocking the LGR4/NF-\u03baB/GPX4 axis, which supports the potential use of quercetin as a therapeutic agent for OSCC.\n\nID: 42523794\nTitle: Programmed cell death mechanisms of traditional plant medicine in prostate cancer therapy.\nAbstract: Prostate cancer (PCa) is a prevalent malignancy in males with high morbidity and mortality. Although treatment modalities have evolved considerably, tumor resistance, recurrence, and metastasis persist, urgently requiring the exploration of alternative therapies for PCa. There is ongoing research on finding and identifying the use of traditional plant medicine (TPM). Cellular homeostasis comprises a sophisticated network of metabolic processes that functions cooperatively to preserve a stable intracellular environment. Programmed cell death (PCD) plays an important role in PCa mechanism. Thus, they represent an effective strategy for targeting PCa. TPM has been proven to induce PCD through multiple pathways and target in the treatment of PCa. Recent reviews have only focused on the one of the PCD, and autophagy, apoptosis, pyroptosis, ferroptosis, and necroptosis are not simultaneously reviewed. The search strategy: articles with the title containing \"prostate cancer\", \"therapeutic\", \"traditional medicine\", \"apoptosis\", \"pyroptosis\", autophagy\", \"in vivo/in vitro\", \"active ingredients\", \"Herbal\", \"real modules\", \"dose\", \"pathway\", \"effects/mechanisms\", \"extract\", \"pure compound\", \"drug type\", \"anticancer activity\", \"Chinese herbal compounds\", \"necroptosis\" and \"ferroptosis\" had been initially selected in the past five years databases of PubMed, Web of Science, and ScienceDirect. The references were screened according to the strategy. Forty-two drugs in the TPM have been chosen in this review. The plant extract, Chinese herbal compound, and pure compound of TPM exhibit significant anticancer activity against PCa by regulating multiple kinds of PCD. More importantly, PI3K/AKT/mTOR, AMPK/mTOR pathways, AKT1/Bcl2/NF-\u03baB, GPBAR1/NF-\u03baB, Keap1/Nrf2/ARE, PINK1/Parkin signaling pathways serve as critical molecular targets mediating the anticancer activities of TPMs in PCD. Autophagy, apoptosis, and ferroptosis are research hotspots, while pyroptosis and necroptosis are less explored. Apoptosis is co-detected with autophagy, or necroptosis. Ferroptosis is co-detected with necroptosis, or pyroptosis. Notably, the interrelationships between these cell death modes are rarely investigated in depth in the treatment of TPM in PCa. TPM has been induced apoptosis, ferroptosis, necroptosis in PCa. But the effect of TPM on the autophagy and pyroptosis need further evidence to clarify the mechanism. Hence, it is imperative to focus on elucidating the role of PCD modulators to refine therapeutic strategies of TPM in PCa.\n\nID: 42523442\nTitle: Supplementation via DAF-16 and pnk-1 driven pantothenate-coenzyme A flux improves disease related stress resistance in C. elegans.\nAbstract: Metabolic pathways are increasingly recognized as tractable targets in aging and disease. Building on prior work demonstrating that supplementation with low-molecular weight metabolites (amino acids, vitamins, and their intermediates) can extend lifespan in Caenorhabditis elegans , we focused on pantothenate (vitamin B 5 ), which is dysregulated in sarcopenic muscle and in several neurodegenerative and metabolic disorders. Pantothenate is the obligate precursor of coenzyme A through a short, highly conserved biosynthetic pathway in which loss-of-function mutations can cause neurodegeneration with brain iron accumulation. In C. elegans , the longevity curtailing transcription factor DAF-16/FOXO has a conserved binding element in the promoter region of pnk-1 , encoding the first enzyme (PNK-1) in the coenzyme A pathway, and pnk-1 is markedly upregulated in long-lived daf-2 (insulin/-like receptor) mutants, implicating coenzyme A metabolism in longevity. Here, we demonstrate that CoA levels naturally increase during early life and decrease towards older age in C. elegans . Dietary pantothenate supplementation increases coenzyme A levels with minimal effects on lifespan but systemic effects on lipid metabolism, mitochondrial dynamics, and muscle structure under basal conditions. Under DAF-16-associated stress conditions, including heat and oxidative stress, pnk-1 expression is upregulated and pantothenate supplementation robustly extends lifespan and improves mobility. Finally, we demonstrate dysregulation of daf-16 and pnk-1 expression in amyotrophic lateral sclerosis (ALS) models, in which pantothenate supplementation confers both lifespan extension and cholinergic neuroprotection.\n\nID: 42523149\nTitle: Novel blood lncRNA biomarkers associated with clinical severity and specific cognitive dimensions in Alzheimer's disease.\nAbstract: BackgroundDifferential expression of long non-coding RNAs (lncRNAs) in brain, serum, and blood show strong potential to distinguish Alzheimer's disease (AD) from healthy controls.ObjectiveTo explore whether lncRNA signatures delineate AD pathology and map to distinct, multidimensional cognitive domains, enhancing specificity in assessing AD severity and progression.MethodsWe profiled 29,603 lncRNAs transcripts in blood samples from 15 AD patients and 15 healthy controls, alongside comprehensive neuropsychological assessments. Generalized Linear Models and Predictive Power Score analyses, with statistical prioritization, identified lncRNAs associated to AD neuropsychological architecture.ResultsSeveral lncRNAs share strongly associated with cognitive performance and AD severity, mapping to genes involved in key AD-related molecular processes, including synaptic and neurotransmitter regulation (e.g., EPHB1, CHRNA4, TEAD1), protein homeostasis and A\u03b2 pathology (e.g., FBXL2, FAM221A, APP), mitochondrial function and cellular stress (e.g., VDAC3, PPT2-EGFL8), neuroinflammation and immune regulation (e.g., TEAD1, EMX2OS, LY6E-DT), epigenetic and transcriptional control (e.g., PRDM2, DLEU1, FIRRE), neuronal excitability (e.g., KCNJ14), and neuroprotection and synaptic plasticity (e.g., SIL1). Novel associations included ferroptosis, DNA stability, microtubule dynamics, and dendritic orientation (e.g., BTB3, DICER1, GNG7, IBA57, NEAT1, POT1, SRD5A3).ConclusionsWe identify candidate lncRNA signatures that may serve as potential biomarkers and enhance our understanding of the molecular basis of the cognitive architecture in AD, opening new avenues for biomarker identification and targeted therapeutic strategies development. Validation in larger, diverse cohorts is essential to confirm their mechanistic contributions to AD.\n\nID: 42523103\nTitle: Heme-copper-A\u03b2 mediated dopamine oxidation through self-sustaining redox cycling.\nAbstract: Alzheimer's disease is characterized by progressive neurodegeneration, with A\u03b2 peptides playing a critical role in disease pathology. Beyond their aggregation into plaques, A\u03b2 peptides can interact with redox-active cofactors such as copper and heme, forming complexes capable of catalyzing ROS generation. While Cu-A\u03b2 is known to oxidise catecholamines like dopamine through redox cycling, the functional implications of ternary heme-Cu-A\u03b2 assemblies remain poorly understood. In this study, we demonstrate that the heme-Cu-A\u03b2 complex catalyzes dopamine oxidation more efficiently than Cu-A\u03b2 alone, driven by a self-sustaining cooperative redox cascade involving Cu-mediated H2O2 generation and subsequent heme-mediated peroxidase-like activity in the presence of the endogenously produced H2O2. Moreover, kinetic analysis and mutant studies reveal the critical contributions of Arg5 in modulating the redox behavior of the complex. These findings establish the heme-Cu-A\u03b2 complex as a potent catalytic assembly capable of altering dopamine homeostasis under oxidative stress, offering new insights into A\u03b2-mediated neurotoxicity in Alzheimer's disease.\n\nID: 42522950\nTitle: Nanomaterials Enable Spatiotemporally Controlled Ultrasound-Triggered Pyroptosis for Cancer Immunotherapy.\nAbstract: Pyroptosis, a highly inflammatory form of programmed cell death (PCD), holds exceptional promise for activating antitumor immunity. However, achieving precise and tumor-selective pyroptosis induction while preserving normal tissue integrity remains a major translational hurdle. Ultrasound has emerged as an ideal exogenous stimulus for this purpose, owing to its noninvasiveness, deep tissue penetration, and precise spatiotemporal control. Through integration with tailored nanomaterials, ultrasound energy can be specifically converted into localized biochemical signals at the tumor site, thereby triggering pyroptosis that potently stimulates antitumor immunity. This review systematically elucidates how rational nanomaterial design enables ultrasound-triggered pyroptosis (sonopyroptosis) through distinct mechanisms, including sonodynamic, sonopiezocatalytic, enzyme-mimetic, and multimodal synergistic pathways. It further delineates the ensuing immune cascade, from innate immune activation and adaptive T cell responses to the remodeling of the immunosuppressive tumor microenvironment (TME), and evaluates the synergistic potential of this approach with emerging immunotherapies such as immune checkpoint blockade (ICB) and cGAS-STING pathway activation. Finally, key challenges in clinical translation are outlined, and future perspectives are proposed to accelerate the development of nanomaterial-mediated ultrasound-triggered pyroptosis for cancer immunotherapy.\n\nID: 42521977\nTitle: Regulated cell death-induced coagulation dysfunction in sepsis.\nAbstract: Regulated cell death (RCD) has emerged as a pivotal upstream mediator supported by correlative preclinical and clinical evidence in the pathogenesis of sepsis-induced coagulopathy (SIC), a life-threatening complication strongly linked to increased mortality. RCD-guided phenotyping integrates pyroptosis, NETosis, ferroptosis, necroptosis, and PANoptosis pathways to systematically redefine SIC - from molecular signatures to targeted interventions. This review comprehensively examines how RCD-derived Damage-Associated Molecular Patterns (DAMPs) mediate coagulation dysfunction, explores subtype-specific biomarkers for patient stratification, and outlines phenotype-directed combination therapies. We further investigate unresolved challenges and future developments in RCD-guided precision immunomodulation, emphasizing the transformative potential of RCD-based frameworks to advance the clinical management of SIC by bridging insights from cell death and thrombosis research.\n\nID: 42521170\nTitle: ROS-responsive chitosan/hyaluronan polyelectrolyte nanogels for targeted chemo-ferroptosis therapy against breast cancer.\nAbstract: Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, has emerged as a promising strategy for combination with chemotherapy in cancer treatment. However, the rational design of delivery systems capable of simultaneously inducing ferroptosis, enhancing chemotherapy efficacy, and reducing systemic toxicity remains a substantial challenge. Herein, we developed a reactive oxygen species (ROS)-responsive, ionically crosslinked chitosan/hyaluronan polyelectrolyte nanogel for targeted chemo-ferroptosis combination therapy. In this system, hyaluronic acid (HA) was first esterified with 1,2-bis (2-hydroxyethylthio) ethylene (BE) and subsequently conjugated with methotrexate (MTX) through a ROS-cleavable linkage, yielding an anionic HA-BE-MTX polymeric prodrug. Protonated chitosan (CS) served as the cationic polymeric component, while sodium tripolyphosphate (TPP) further stabilized the nanogel network through ionic crosslinking. Sorafenib (SOR), a ferroptosis inducer, was physically encapsulated during the ionotropic gelation process. The resulting R-NGMS nanogels were designed to maintain colloidal stability under physiological conditions and to undergo ROS-triggered network loosening and drug release in the tumor microenvironment, where oxidative stress is elevated. This dual-delivery system enabled ROS-responsive MTX release and SOR-mediated ferroptosis induction, thereby promoting ROS accumulation, glutathione depletion, GPX4 suppression, lipid peroxidation, and apoptosis in breast cancer cells. In vivo studies demonstrated that R-NGMS efficiently accumulated in 4T1 tumors through prolonged circulation and HA-CD44-mediated tumor targeting, achieving a tumor growth inhibition rate of 75.85% with reduced systemic toxicity compared with free drug treatment. These findings demonstrate that ionically crosslinked CS/HA-based polyelectrolyte nanogels provide an effective and selective platform for ROS-responsive chemo-ferroptosis combination therapy.\n\nID: 42521052\nTitle: Exploring Ferroptosis: Unraveling Its Potential Role in Autistic Spectrum Disorder.\nAbstract: Autism spectrum disorder (ASD) is a diverse neurodevelopmental disorder characterized by ambiguous etiological mechanisms and the absence of recognized disease-modifying pharmacotherapies. Ferroptosis, an iron-dependent and lipid peroxidation-driven mechanism of regulated cell death, has been associated with neurodevelopment and neurodegeneration, prompting interest in its potential role in ASD. This narrative review consolidates from molecular and clinical studies, animal models, and in vitro systems to assess ferroptosis as a candidate mechanistic pathway, biomarker source, and therapeutic target in ASD. Peripheral transcriptomic analyses reveal differentially expressed ferroptosis-related genes, ferroptosis-based molecular clusters, and immune-activated subtype in children with ASD, facilitating the development of ferroptosis-derived diagnostic and scoring models with modest yet reproducible discrimination. Clinical data associate maladaptive polyunsaturated fatty acid profiles, increased lipid peroxidation products, and adverse docosahexaenoic acid/arachidonic acid ratio with autistic social impairments, aligning with ferroptosis-prone conditions. In rodent models, genetic or pharmacological modulation of DDIT4-PI3K/Akt signaling, Nrf2/GPX4/xCT antioxidant systems, and ferritinophagy mitigates ASD-like social deficits, repetitive behaviors, anxiety-like phenotypes, and liver pathology. Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways, indicating subtype-specific ferroptosis resistance. These findings suggest a complex, context-dependent role of ferroptosis and ferroptosis resistance in ASD, interacting with immune dysregulation, redox imbalance, and peripheral organ involvement. Nevertheless, longitudinal and interventional studies integrating brain, peripheral, and cellular data are required to establish causality, define meaningful ferroptosis-related signatures, and evaluate the safety and efficacy of ferroptosis-modulating interventions.\n\nID: 42520640\nTitle: Ultrasmall nanosonocatalyst induces PANoptosis to suppress ovarian cancer: From patient-derived organoids to in vivo models.\nAbstract: Ovarian cancer represents one of the most lethal gynecological malignancies, marked by a high recurrence rate and dismal prognosis. Existing targeted treatments face challenges such as limited applicability, modest effectiveness, and considerable costs, underscoring the demand for novel therapeutic alternatives. Growing research suggests that triggering a significant intracellular reactive oxygen species (ROS) surge can selectively induce oxidative destruction and death in tumor cells with compromised redox balance, while largely sparing normal cells. In this work, we designed lanthanum-doped zinc sulfide (ZnS:La) nanocrystals as an efficient sonocatalyst to augment sonodynamic treatment for ovarian cancer. Under ultrasound exposure, ZnS:La demonstrated improved charge separation and a notable boost in ROS generation, leading to substantial oxidative injury in cancer cells. Concurrently, the slow release of La3+ ions contributed to lysosomal membrane disruption, increasing cellular susceptibility to oxidative stress. These processes promoted the formation of PANoptosomes and initiated PANoptosis-a synergistic type of programmed cell death encompassing apoptosis, pyroptosis, and necroptosis. In evaluations using patient-derived organoids, subcutaneous grafts, and orthotopic ovarian tumor models, ultrasound-activated ZnS:La consistently inhibited tumor progression and spread. This study introduces a powerful sonocatalyst-based approach to engage multiple programmed cell death mechanisms, highlighting a potential new direction for ovarian cancer therapy.\n\nID: 42520529\nTitle: RRM2 promotes lung adenocarcinoma progression and is associated with ferroptosis-inducer sensitivity through the NRF2/GPX4 signaling axis.\nAbstract: Lung adenocarcinoma (LUAD) is a leading cause of cancer-related mortality, characterized by aggressive progression and therapy resistance. Ferroptosis, an iron-dependent form of regulated cell death, has emerged as a promising therapeutic avenue. However, the role of Ribonucleotide Reductase M2 (RRM2) in ferroptosis regulation and its relevance to LUAD progression remain incompletely understood. We integrated bulk transcriptomic, proteomic, WGCNA, and single-cell datasets to evaluate the clinical and biological relevance of RRM2 in LUAD. Functional validation was performed using RRM2 knockdown, ferroptosis-inducer sensitivity assays, ferroptosis-related biochemical assays, NRF2/GPX4 pathway analysis, rescue experiments, and xenograft models. RRM2 was significantly upregulated in LUAD tissues and was associated with poor overall survival. Single-cell analysis localized high RRM2 expression to a proliferative tumor cell subpopulation enriched in cell cycle- and immune-related pathways. Functionally, RRM2 knockdown suppressed LUAD cell proliferation and tumor growth and was accompanied by increased ROS, lipid ROS, Fe\u00b2\u207a, and MDA levels and decreased GSH levels. RRM2 depletion also increased ferroptosis-inducer sensitivity, with enhanced erastin and RSL3 sensitivity in A549 cells and clear RSL3 sensitization in PC9 cells. In parallel, RRM2 silencing was associated with reduced NRF2 and GPX4 expression, decreased NRF2 nuclear-to-cytosolic signal intensity, and increased ACSL4 expression. NRF2 overexpression partially restored GPX4 immunofluorescence intensity in RRM2-knockdown cells. Moreover, NRF2 overexpression or Ferr-1 treatment partially reversed the growth-suppressive effects induced by RRM2 deficiency in vitro and in vivo. RRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis. These findings support RRM2 as a candidate prognostic biomarker and a potential therapeutic target in LUAD, while the precise molecular relationship between RRM2 and the NRF2/GPX4 axis warrants further investigation.\n\nID: 42517944\nTitle: RNA cytosine modifications regulates musculoskeletal disorders.\nAbstract: The RNA cytosine modification (RCM), particularly 5-methylcytosine (m5C) and N4-acetylcytidine (ac4C) modification, represents a rapidly advancing frontier in recent epitranscriptomic research. These reversible modifications intervene in the process of RNA generation, thus playing a critical role in the post-transcriptional regulation of RNA, including nuclear export, ribosome assembly, translation, and stability, thereby modulating various fundamental biological processes, such as cellular proliferation, differentiation, and cell death. Musculoskeletal disorders (MSDs), including osteoarthritis (OA), osteoporosis (OP), rheumatoid arthritis (RA), osteosarcoma (OS), and intervertebral disc degeneration (IVDD), are a major class of debilitating conditions that affect the locomotor system. Emerging evidence has demonstrated that dysregulation of m5C or ac4C modification contributes significantly to MSD pathogenesis through multiple mechanisms, including chondrocyte pyroptosis, lipid droplet dynamics, macrophage polarization, osteogenic and osteoclastic differentiation, synovial hyperplasia and invasion, and tumor-associated metabolic reprogramming. Moreover, these modifications are mechanistically linked to key pathological hallmarks, such as immune cell infiltration, ferroptosis, autophagy, and aberrant mechanical compression transduction. Pharmacological targeting of m\u2075C- and ac\u2074C-regulatory enzymes has been indicated to have therapeutic potential in animal models of MSDs. Herein, we present this review that systematically addresses the molecular basis and current knowledge on the mechanisms underlying RCMs in a variety of MSDs, along with translational strategies targeting these epitranscriptomic pathways. Finally, we present our thoughts and comments on this topic.\n\nID: 42517861\nTitle: Senotherapeutics for Knee Osteoarthritis.\nAbstract: Osteoarthritis (OA) is a chronic disease that imposes a significant economic burden and deteriorates quality of life. Nevertheless, current therapeutic options for OA are limited to symptomatic remedies. As such, there is a high interest in novel methods for treating or preventing OA. One of the most promising medication modalities is through the clearance of cells that are cell cycle arrested but resistant to apoptosis, termed senescent cells. Additionally, these cells are also resistant to alternative programmed cell death modes, such as ferroptosis and pyroptosis. Senescent cells tend to accumulate with age due to increasing cellular and genetic damage. These cells can release inflammatory factors and signaling molecules termed senescence-associated secretory phenotype (SASP). In addition to triggering an inflammatory milieu in joints, SASP can also induce senescence in other cells through autocrine signaling. It has been shown via in vitro and in vivo tests that clearance of senescent cells through a class of drugs known as senolytics, or neutralization of SASP with senomorphics, can improve OA pathogenesis. Following these results, several clinical trials have been conducted to evaluate the efficacy of senotherapeutics against knee OA. Yet there remains a need for a comprehensive assessment of safety and optimization of senotherapeutic treatment regimens for knee OA. To this end, a better understanding of molecular mechanisms behind chondrocyte senescence and knee OA pathogenesis is necessary. Identification of novel compounds that can specifically target chondrocyte senescence pathways can assist in developing more effective therapies against OA.\n\nID: 42517390\nTitle: Targeting Ferroptosis-associated Histone Acylation for Amelioration of Neurological Disease.\nAbstract: Ferroptosis is an iron-dependent, lipid peroxidation-driven form of programmed cell death. There is substantial evidence supporting the critical role of ferroptosis in multiple neurological diseases, including stroke, Alzheimer's disease, Parkinson's disease, epilepsy, and traumatic brain injury. Histone acylation, an important epigenetic mechanism, effectively regulates ferroptosis. To date, the regulation of ferroptosis by histone acylation in neurological diseases has rarely been summarized. Therefore, this review discusses the key mechanisms by which histone acylation regulates ferroptosis, including iron metabolism, antioxidant defense, and lipid peroxidation. Additionally, we summarize the latest advances in understanding the role of histone acylation in ferroptosis and its relation to the emerging hallmarks of neurological diseases. Furthermore, we provide the prospect of targeting key regulatory factors of histone acylation, such as writers, erasers, and readers, for potential therapeutic strategies to ameliorate neurological diseases.\n\nID: 42517186\nTitle: Mitochondrial Dysfunction at the Crossroads of Necroptosis: Mechanisms, Molecular Mediators, and Therapeutic Opportunities.\nAbstract: The conceptual landscape of cell death has evolved beyond the traditional dichotomy of apoptosis and necrosis to encompass diverse regulated pathways including necroptosis, autophagy, ferroptosis, and pyroptosis. Necroptosis, a caspase-independent inflammatory form of programmed cell death, has emerged as a critical driver of the pathogenesis of cardiovascular disorders, neurodegenerative diseases, and cancer. Concurrently, our understanding of mitochondrial biology has undergone a paradigm shift: mitochondria are no longer viewed merely as bioenergetic powerhouses, but as dynamic signalling hubs that orchestrate metabolic reprogramming, cellular homeostasis, and ultimate cell fate decisions. In this regard, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This review delineates the mechanistic interplay between necroptosis and mitochondrial dysfunction and systematically analyzes the key molecular mediators and pathological pathways through which mitochondrial dysregulation drives necroptotic activation. Furthermore, this review identifies actionable therapeutic targets and translational strategies for modulating necroptosis in related diseases.\n\nID: 42517156\nTitle: Bibliometric Trends in Inflammasome\u2011Driven Pyroptosis and Cardiovascular Disease.\nAbstract: This bibliometric study provides the first comprehensive synthesis of inflammasome\u2011driven pyroptosis research in cardiovascular disease (CVD), systematically mapping its evolution. Pyroptosis, an inflammatory form of programmed cell death triggered by inflammasome activation, plays a critical role in various CVDs, including hypertension, ischemia\u2011reperfusion injury (I/R injury), atherosclerosis, and heart failure (HF). Despite rapid growth of the literature, no bibliometric analysis has specifically focused on this area. Data were retrieved from the Web of Science Core Collection (1998-April 27, 2025). Bibliometric and visual analyses were performed using CiteSpace and VOSviewer to examine publication trends, country/region, funding agency, institution, author, journal, subject category, co\u2011cited reference, keyword co\u2011occurrence, and emerging hotspots. A total of 4,511 documents (2,918 original articles and 1,593 reviews) were included. China contributed 2,259 publications (50.1% of total) with 56,326 citations; the United States contributed 1,022 publications (22.7%) with 79,057 citations and the highest country\u2011level h\u2011index (147); and Italy ranked third with 290 publications (6.4%). Harvard University and its affiliated institutions led in both publication quantity and impact (h\u2011index, citations per article). Keyword co\u2011occurrence identified four clusters: pyroptosis mechanisms, NLRP3 inflammasome, signaling pathways, and CVDs. Recent bursts (2024\u20112025) highlight \"pyroptosis\" and \"ferroptosis\" as emerging frontiers. This bibliometric study identifies NLRP3 as the central research focus in inflammasome\u2011driven pyroptosis research, with the strongest citation burst. The findings reveal a shift from basic mechanistic studies toward translational research, highlighting emerging priorities such as the crosstalk between pyroptosis and ferroptosis and the need for patient stratification in future clinical trials.\n\nID: 42517086\nTitle: Berberine-induced ferroptosis as a novel anti-cancer strategy: Molecular, epigenetic and translational perspectives.\nAbstract: Cancer cells frequently evade therapies that depend on apoptosis, necessitating the exploration of alternative cell death mechanisms. Ferroptosis, an iron-dependent regulated cell death characterized by lethal lipid peroxidation, has emerged as a promising strategy for cancer treatment. Recent studies have identified berberine, an isoquinoline alkaloid derived from Coptis chinensis and Berberis species, as an inducer of ferroptosis in various malignancies through its multitarget effects. This review systematically elucidates the molecular pathways through which berberine induces ferroptosis. These pathways include the inhibition of the System Xc-/glutathione/glutathione peroxidase 4 antioxidant axis, disruption of iron homeostasis via ferritinophagy, inhibition of mitochondrial complex I, and regulation of the upstream regulators p53, nuclear factor erythroid 2-related factor 2, and Gli1/signal transducer and activator of transcription 3 axis. Evidence specific to various cancer types, including nasopharyngeal, lung, colorectal, gastric, hepatocellular, pancreatic, prostate cancer, and osteosarcoma, was critically evaluated. Translational strategies, such as combination therapy, nanodelivery systems, and machine learning-directed structural optimization, have been examined. Additionally, the challenges of low bioavailability, resistance to ferroptosis, and complex immunological responses are discussed. Preclinical evidence suggests that berberine exhibits significant epigenetic activity, including the inhibition of DNA methyltransferases (DNMT1/DNMT3), histone modifications (H3K9me3 via SETDB1, H3K27me3 via EZH2), and modulation of oncogenic/tumor-suppressor microRNAs (e.g., miR-21, miR-155). These actions enhance its ferroptotic effects and may synergistically increase the sensitivity of cancer cells to lipid peroxidation. Although primarily based on preclinical findings, these epigenetic mechanisms represent a crucial and underexplored aspect of berberine's anticancer potential.

Ferroptosis, an iron-dependent, non-apoptotic form of regulated cell death characterized by the lethal accumulation of lipid peroxides, represents a pharmacologically significant vulnerability in cancers that are resistant to apoptosis and tolerant to drugs. The resistance to ferroptosis, induced by the aberrant overexpression of the epigenetic enzyme histone deacetylases (HDACs) and the sustained transcriptional activity of key antiferroptotic targets, particularly GPX4 and SLC7A11, is enforced through epigenetic mechanisms. This review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways. These pathways include the transcriptional silencing of SLC7A11 and subsequent glutathione depletion, disruption of intracellular iron homeostasis via ferroportin downregulation, enhancement of mitochondrial ROS-induced lipid peroxidation, and suppression of the HDAC3-NRF2-GPX4 antiferroptotic axis. The specific roles of HDAC1, HDAC3, and HDAC10 in colorectal, lung, gastric, and hematological cancers are elucidated. Additionally, the review discusses hybrid molecules of HDAC-ferroptosis, combination strategies with GPX4 inhibitors, and immunochemotherapy. Considerations such as isoform selectivity, biomarker development, and clinical translation are addressed, highlighting HDAC inhibitor-mediated ferroptosis sensitization as a promising strategy to overcome drug resistance in cancer. See also the graphical abstract(Fig. 1).\n\nID: 42517079\nTitle: Doxorubicin-induced cardiotoxicity: Is ferroptosis the primary driver or a downstream amplifier?\nAbstract: Doxorubicin (Dox) is one of the most effective anticancer agents used to treat a wide range of solid tumors as well as hematological malignancies. However, its associated cardiotoxicity poses a major challenge for its therapeutic use. There are numerous studies exploring the underlying cellular mechanisms behind Dox-induced cardiotoxicity. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity. Under normal physiology, cardiomyocytes maintain a highly regulated iron homeostasis, while the polyunsaturated fatty acid-rich membrane also renders it susceptible to peroxidation, a hallmark of ferroptosis. Dox-induced cardiotoxicity disrupts the coordinated control of iron metabolism, generating reactive oxygen species, propagating lipid peroxidation, and impairing mitochondrial function. Progressive structural damage and functional loss of cardiomyocytes culminate in permanent cardiac cell death. Therefore, targeting regulatory nodes of ferroptosis may be beneficial for ameliorating Dox-induced cytotoxicity. However, it is still not clear whether the ferroptotic process merely acts as an initiator or can further act as an amplifier to upregulate the downstream signaling molecules in this cell death cascade. This review offers an overview of perspectives on the ferroptotic pathway and introduces readers to a novel driver-amplifier concept. See also the graphical abstract(Fig. 1).\n\nID: 42517042\nTitle: Mechanistic insights into lipoprotein(a)-induced cardiomyocyte ferroptosis via ROS/p38/p53 signaling.\nAbstract: Lipoprotein(a) [Lp(a)], a low-density lipoprotein-like molecule covalently linked to apolipoprotein (a), is a residual cardiovascular risk factor with established atherogenic and antifibrinolytic properties. However, its direct involvement in cardiomyocyte injury mechanisms remains unclear. This study aimed to investigate the effects of Lp(a) on cardiomyocytes. A combination of in vitro cell culture and in vivo small animal models were used for investigations. Lp(a) induced ferroptosis through a redox-sensitive pathway via sequential p38 MAPK activation and p53-mediated transcriptional regulation. Exposure of AC16 human cardiomyocytes to Lp(a) triggered hallmark ferroptotic events, including intracellular Fe2+ accumulation, an increase in malondialdehyde (MDA) levels, and concurrent increases in p38 MAPK (p-p38) phosphorylation. Pharmacological blockade of p38 using SB203580 or siRNA-mediated p38 silencing significantly attenuated these ferroptotic markers, confirming the central role of p38 in sensitizing cardiomyocytes to ferroptosis. p38 activation drove the nuclear translocation of p53, with both pharmacological p53 inhibition (pifithrin-\u03b1) and genetic p53 knockdown effectively mitigating Lp(a)-induced lipid peroxidation and cell death. Furthermore, Lp(a) promoted an increase in intracellular reactive oxygen species (ROS) levels and initiated p38 phosphorylation, subsequently activating p53 to suppress SLC7A11 expression. These cellular findings were validated in vivo using Lp(a)-treated C57BL/6J mice, which recapitulated cardiac dysfunction, as indicated by characteristic ferroptotic markers: myocardial Fe2+/MDA elevation, glutathione/cysteine depletion, and p38-p53 axis activation. Lp(a) activates p38 by increasing intracellular ROS levels and promotes ferroptosis in cardiomyocytes via SLC7A11 inhibition, which depends on p53 activation.\n\nID: 42516559\nTitle: Cimicifuga foetida L. polysaccharide alleviates ulcerative colitis by inhibiting pyroptosis and regulating gut microbiota.\nAbstract: Cimicifuga foetida L. is widely applied in the clinical treatment of ulcerative colitis (UC); however, its active components and mechanisms have not been deeply investigated. The objective of this study is to investigate the potential bioactive constituents of C. foetida L. for the treatment of UC, and elucidate its therapeutic mechanism. The crude polysaccharide of C. foetida L. was extracted by hot water and purified by DEAE Sepharose\u2122 Fast Flow column to obtain, and named SM05. The structure was determined by HPLC, FT-IR and SEM. The effect of polysaccharide (SM05) on the mouse UC model and its mechanism of action were investigated using a dextran sodium sulfate (DSS)-induced UC model. Changes in body weight, disease activity index, colon length, organ index, histopathological injury, cytokine expression and intestinal tight junction proteins were measured to evaluate the effect of SM05 on UC. IHC, RT-qPCR, and 16s rDNA sequencing were performed to elucidate the underlying mechanism. SM05 is mainly composed of mannose, glucose, galactose, and arabinose. SM05 exerts antioxidant effects by activating the Nrf2/Keap1 pathway, thereby inhibiting the NLRP3-induced pyroptosis pathway. This reduces abnormal intestinal cell death and the secretion of inflammatory cytokines, thus protecting the intestinal barrier and suppressing further inflammation. Additionally, SM05 modulates the gut microbiota structure in mice with ulcerative colitis by reducing pathogenic bacteria (e.g., Bacteroides and Desulfovibrio) that damage the intestinal barrier and increasing the abundance of beneficial bacteria (e.g., Akkermansia and Saccharibacteria), thereby alleviating the progression of ulcerative colitis. In the preliminary biological assessment, the polysaccharide subfraction SM05 alleviated the symptoms of UC induced by DSS. This effect may be related to the activation of the Nrf2/Keap1 pathway, the inhibition of pyroptosis, and the regulation of the intestinal microbiota.\n\nID: 42515900\nTitle: Targeting Ferroptosis in Adenocarcinoma of the Esophagogastric Junction: From a Natural Compound to Clinical Translation.\nAbstract: Ferroptosis-cell death driven by iron-is gaining traction in oncology. A study published in Current Cancer Drug Targets (CCDT) shows that a natural compound, Macranthoside B (MB), inhibits the activity of Adenocarcinoma of the Esophagogastric Junction (AEG) and that NRF2-mediated ferroptosis is involved in its regulation. This editorial discusses the mechanistic implications of that study, with particular attention to the NRF2/NCOA4-related ferritinophagy axis, while also emphasizing the limitations that should be addressed before clinical translation. Although the findings provide a useful preclinical rationale for exploring ferroptosis-oriented therapeutic strategies in AEG, key questions remain regarding the validation of the causal pathway, pharmacokinetics, systemic toxicity, tumor selectivity, model representativeness, and biomarker-based patient stratification. Therefore, Macranthoside B should currently be viewed as a promising experimental compound rather than a clinically established therapeutic candidate. Further in vivo studies and carefully designed translational investigations are required to determine whether this natural compound can be advanced toward AEG treatment.\n\nID: 42515887\nTitle: Establishment and Validation of a Necroptosis-Related Long Noncoding RNA Prognostic Model for Non-Small Cell Lung Cancer.\nAbstract: Non-small cell lung cancer (NSCLC) accounts for over 85% of lung cancers, and current immunotherapies benefit only a subset of patients. Necroptosis, a regulated form of necrotic cell death, has emerged as a potential therapeutic axis in tumours resistant to apoptosis. This study aimed to develop and validate a necroptosis-related long noncoding RNA (lncRNA) prognostic signature for NSCLC and to explore its associations with tumour immune contexture and predicted drug sensitivity. RNA-seq and clinical data from TCGA and GTEx (1,128 tumours; 110 normal lung samples; 1,027 patients after filtering) were analysed. Necroptosis-related lncRNAs were identified by co-expression analysis with 67 necroptosis genes (Pearson r > 0.4, P < .001). Candidate lncRNAs associated with overall survival were selected by univariable Cox regression, refined through LASSO-penalised Cox regression with 10-fold cross-validation repeated 1,000 times, and further filtered by multivariable Cox analysis to construct the final risk model. Model performance was evaluated using time-dependent ROC curves and a clinical nomogram. QRT-PCR validated differential expression in A549 and NCI-H1299 versus BEAS-2B cell lines. Immune profiling was performed using seven deconvolution algorithms and single-sample GSEA (ssGSEA). Consensus clustering was applied to classify tumour immune phenotypes, and drug sensitivity was estimated using the pRRophetic algorithm. A 12-lncRNA signature stratified overall survival across training, test, and whole cohorts and remained independent of tumour stage in multivariable analysis. Time-dependent ROC curves yielded AUCs of 0.684, 0.652, and 0.624 at 1, 3, and 5 years, respectively. A nomogram integrating the risk score with clinicopathological variables demonstrated strong calibration. qRT-PCR confirmed differential expression of the model lncRNAs between NSCLC and normal bronchial epithelial cell lines. GSEA revealed enrichment of metabolic programmes in low-risk tumours and adhesion/cytoskeletal pathways in high-risk tumours. Immune deconvolution indicated a mixed immune milieu in high-risk tumours, with increased infiltration estimates concurrent with elevated expression of inhibitory checkpoints. Consensus clustering defined two groups: an inflamed \"hot-like\" cluster with higher immune/stromal scores and lower predicted IC50 values for multiple targeted and cytotoxic agents, and a comparatively \"cold-like\" cluster. The 12-lncRNA risk model captures biologically distinct tumour states characterised by divergent pathway activation, distinct immune microenvironmental composition, and predicted drug-sensitivity profiles. The co-occurrence of immune infiltration and inhibitory checkpoint enrichment in high-risk tumours suggests immune dysfunction rather than effective antitumour immunity, with direct implications for immunotherapy stratification. This necroptosis-related lncRNA signature provides a framework for prognostic prediction, tumour immune phenotyping, and therapeutic prioritisation in NSCLC. Prospective external validation and mechanistic functional studies are warranted to confirm clinical applicability.\n\nID: 42515796\nTitle: From Whole-Plant Phytochemistry to Precision Oncology: A Paradigm-Shifting Systematic Review of Lycium barbarum L. (Goji Berries).\nAbstract: Medicinal and edible plants are promising resources for low-toxicity therapeutics and precision nutrition. Lycium barbarum L. (goji berry), a quintessential medicine-food homologous herb with 2000 years of ethnopharmacological use, has attracted global attention. However, existing studies are limited by fruit-centric bias, lack of correlation between processing methods, component properties and bioactivities, and incomplete antitumor mechanistic understanding. This systematic review establishes a holistic research paradigm that integrates whole-plant resource utilization, processing-property-bioactivity associations, multi-target pharmacology, and clinical translation. We delineate tissue-specific distributions of core bioactives (polysaccharides, phenolics, carotenoids, alkaloids) and their synergistic networks underlying antioxidant, anti-inflammatory, hypoglycemic, and immunomodulatory effects. Critically, we systematically summarize preclinical evidence for the antitumor potential of goji berries, identifying four proposed non-overlapping cell death pathways (apoptosis, cell cycle arrest, ferroptosis, autophagy) and proposed unique roles in reversing multi-drug resistance, alleviating chemoradiotherapy toxicity, and serving as biocompatible nanocarriers, all of which remain predominantly at the preclinical stage. We further propose a three-stage evidence-based roadmap to address key translational bottlenecks. This review bridges the gap between traditional ethnopharmacology and modern precision nutrition, providing a scientific foundation for the sustainable development of the global goji berry industry.\n\nID: 42515756\nTitle: Neuroprotective Effects of Choline Alfoscerate in Experimental Diabetic Peripheral Neuropathy.\nAbstract: Background/Objectives: Diabetic peripheral neuropathy (DPN) is a common and debilitating complication of diabetes mellitus characterized by progressive nerve degeneration and chronic neuropathic pain. Current therapies, including pregabalin, primarily provide symptomatic pain relief and have limited effects on preventing structural nerve damage. Therefore, the development of disease-modifying therapies remains an important unmet clinical need. This study investigated the neuroprotective effects of choline alfoscerate (CA) and its ability to attenuate mechanical hypersensitivity in a streptozotocin (STZ)-induced rat model of DPN. Methods: Diabetes was induced in rats using STZ, and administration protocols were optimized to establish sustained hyperglycemia while minimizing mortality. CA treatment was initiated immediately after STZ administration and continued throughout the study period. Mechanical sensitivity was assessed using the von Frey test. Histopathological examination of sciatic nerves was performed to evaluate structural alterations, and serum biochemical and lipid parameters were analyzed to assess systemic metabolic changes. Results: STZ-treated diabetic rats developed persistent hyperglycemia, mechanical allodynia, elevated serum triglyceride levels, and marked structural deterioration of sciatic nerve fascicles. CA treatment significantly increased paw withdrawal thresholds despite sustained hyperglycemia, indicating attenuation of mechanical hypersensitivity independent of glycemic control. Histopathological evaluation demonstrated reduced nerve fiber degeneration, attenuation of edema-like changes, and preservation of sciatic nerve architecture in CA-treated animals. In addition, CA significantly reduced serum triglyceride levels compared with diabetic controls. Conclusions: CA attenuated mechanical hypersensitivity and exerted neuroprotective effects in STZ-induced diabetic rats. These benefits occurred independently of glucose lowering and were accompanied by improvements in nerve morphology and lipid metabolism. The findings suggest that CA may represent a promising therapeutic candidate for preserving peripheral nerve integrity and attenuating neuropathic progression in diabetic peripheral neuropathy.\n\nID: 42515753\nTitle: Context-Dependent Modulation of Ferroptosis by Metformin: Mechanisms, Therapeutic Implications and Open Questions.\nAbstract: Ferroptosis is an iron-dependent regulated form of cell death characterized by lethal lipid peroxidation and is increasingly implicated in cancer, neurodegenerative diseases, cardiovascular injury, and metabolic disorders. Metformin, a widely prescribed antidiabetic biguanide, exerts pleiotropic effects beyond glucose lowering and has emerged as a context-dependent regulator of ferroptosis. In malignant cells, metformin may enhance ferroptotic susceptibility through activation of AMP-activated protein kinase (AMPK), suppression of mechanistic target of rapamycin (mTOR) signaling and SLC7A11, induction of ferritinophagy, mitochondrial complex I stress, and promotion of lipid peroxidation. Conversely, in normal or stressed non-malignant tissues, metformin may limit ferroptotic injury by activating nuclear factor erythroid 2-related factor 2 (NRF2), supporting glutathione peroxidase 4 (GPX4) and SLC7A11-dependent antioxidant defenses, improving mitochondrial quality control, and stabilizing iron homeostasis. This review synthesizes the molecular basis of this duality, evaluates therapeutic opportunities in oncology and cytoprotection, and outlines biomarker-driven and clinical trial strategies required for translation. Overall, metformin should not be regarded as a universal ferroptosis inducer or inhibitor, but rather as a context-dependent metabolic regulator whose effects are shaped by cell type, dose, exposure duration, transporter expression, iron status, and antioxidant capacity.\n\nID: 42515709\nTitle: TCM-Derived Small Molecules Targeting Metabolic Vulnerabilities in NSCLC: Ferroptosis-Centered Mechanisms and Emerging Cuproptosis- and Disulfidptosis-Related Vulnerabilities.\nAbstract: Non-small cell lung cancer (NSCLC) remains the leading cause of cancer-related mortality worldwide and is characterized by therapeutic resistance, metabolic plasticity, and immune evasion. Accumulating evidence indicates that metabolic reprogramming not only supports tumor growth but also creates exploitable vulnerabilities linked to regulated cell death. Traditional Chinese medicine (TCM)-derived small molecules have attracted increasing attention owing to their structural diversity, multitarget properties, and broad pharmacological activities. In this review, we summarize recent advances in TCM-derived compounds targeting metabolism-associated regulated cell death in NSCLC, with a primary focus on ferroptosis and a cautious discussion of emerging cuproptosis- and disulfidptosis-related mechanisms. Ferroptosis has been extensively investigated in this context, with natural compounds shown to induce cell death through coordinated regulation of cystine transport, glutathione metabolism, GPX4 activity, iron homeostasis, and lipid peroxidation. In parallel, emerging studies suggest that certain natural products may influence copper-dependent cell death pathways and metabolic states associated with disulfide stress. These processes are closely linked to distinct metabolic features of NSCLC, including lipid dependency, copper homeostasis, and glucose utilization. Finally, we discuss major challenges for clinical translation, including poor bioavailability, off-target toxicity, insufficient biomarker stratification, and limited high-quality evidence, and highlight emerging strategies such as nanodelivery systems, structural optimization, and targeted protein degradation approaches. Overall, TCM-derived small molecules represent a promising source of metabolism-targeted therapeutics and provide a foundation for further exploration of regulated cell death in NSCLC. Current evidence is strongest for ferroptosis induction, whereas cuproptosis- and disulfidptosis-related mechanisms remain emerging areas that require further experimental validation in NSCLC models.\n\nID: 42515190\nTitle: Oxidative Stress in Biotoxin-Induced Liver Injury: From ROS Generation to Cell Death and Therapeutic Intervention.\nAbstract: Exposure to diverse naturally occurring biotoxins-originating from fungal, plant, and algal sources-poses a severe and escalating threat to global public health. The liver, due to its pivotal role in toxin metabolism, faces an increased risk of injury from toxin accumulation. Although extensive research has been conducted on toxin-induced hepatic injury, the heterogeneity of oxidative stress mechanisms across different injury phenotypes (such as necrosis, steatosis, and fibrosis) remains poorly understood. This review systematically addresses this gap by establishing oxidative stress as the central, convergent mechanism underlying biotoxin-induced liver injury. By critically comparing representative toxins, we examine the role of oxidative stress in various biotoxin-induced hepatic injury phenotypes and their underlying molecular mechanisms. Furthermore, we discuss the specific involvement of interconnected signaling cascades-specifically the Nrf2, NF-\u03baB and MAPK pathways-in orchestrating different modes of cell death (including apoptosis, ferroptosis, and necroptosis), and summarize antagonistic strategies for biotoxin-induced hepatic injury from an oxidative stress perspective, highlighting their translational potential and providing a robust rationale for developing broad-spectrum, redox-targeted therapies.\n\nID: 42514879\nTitle: Dual Targeting of AChE Inhibition and GPX4 Binding by Plant-Derived Compounds for the Treatment of Alzheimer's Disease: Insights from Molecular Docking and Molecular Dynamics Simulations.\nAbstract: Background/Objectives: Alzheimer's disease (AD) is primarily characterized by cholinergic dysfunction, for which acetylcholinesterase (AChE) inhibition remains the mainstay of symptomatic treatment. However, additional hypotheses such as ferroptosis-an iron-dependent form of regulated cell death-have gained prominence in explaining disease progression. Glutathione peroxidase 4 (GPX4), a critical antioxidant enzyme, plays a protective role by suppressing ferroptotic pathways. In this context, identifying phytochemicals capable of inhibiting AChE and exhibiting activator-like binding toward GPX4 may provide a dual therapeutic benefit. This study aimed to identify such dual-acting compounds through a structure-based virtual screening approach. Methods: A total of 3014 natural compounds were collected from three curated databases: NPACT, HIT, and HIM. Molecular docking was performed against GPX4 (7U4I) and AChE (7D9Q). Compounds demonstrating high affinity for both targets were shortlisted. Z-score normalization and statistical ranking were used to select the best two dual-target compounds. Results: Out of 3014 compounds, 68 showed dual-binding potential. Among these, NPACT00189 (docking scores: -6.720 kcal/mol for GPX4; -8.983 kcal/mol for AChE) and NPACT01210 (docking scores: -5.813 kcal/mol for GPX4; -9.640 kcal/mol for AChE) were identified as top candidates based on docking scores. Molecular dynamics (MD) simulations were conducted for both compounds for 250 ns on the AChE binding site and the allosteric site of GPX4. The results indicated that NPACT00189 maintained stable interactions throughout the simulation period at both targets, indicating its dual-targeting potential. Conclusions: NPACT00189 represents a promising dual-target candidate for further investigation in AD therapy. Its potential requires confirmation through comprehensive in vitro and in vivo studies.\n\nID: 42526093\nTitle: Ecotoxicological responses of aquatic macrophytes to 2,4-D: A global synthesis of species sensitivity and ecological risk.\nAbstract: The widespread use of 2,4-dichlorophenoxyacetic acid (2,4-D) has raised concern about its persistence, mobility, and effects on non-target aquatic vegetation in freshwater ecosystems. Here, we provide a global synthesis of the ecotoxicological responses of aquatic macrophytes to 2,4-D based on a PRISMA-guided systematic review of 86 peer-reviewed studies published between 1947 and 2025. A consistent gradient of species-specific sensitivity was observed across macrophyte growth forms. The submerged species Myriophyllum spicatum showed high susceptibility, with EC\u2085\u2080 values of 0.04-0.182 mg/L and marked growth inhibition at low concentrations, whereas floating species such as Lemna minor and Pontederia crassipes were more tolerant, requiring higher concentrations (7.08 to >100 and 8.1 mg/L, respectively) to produce comparable effects. Importantly, this sensitivity ranking was consistent across laboratory and field experimental settings. These interspecific differences likely reflect variation in herbicide uptake, translocation, and detoxification capacity associated with growth form. The overlap between EC\u2085\u2080 values for M. spicatum and regulatory thresholds for 2,4-D in surface waters suggests that current limits may be insufficient to protect sensitive submerged macrophyte communities. Regarding remediation, L. minor and Salvinia natans emerged as the most promising candidates for phytoremediation, while P. crassipes showed limited capacity to reduce herbicide concentrations in water. Despite advances, no study directly compared oxidative stress biomarkers between submerged and floating species, representing a critical gap in understanding the biochemical basis of the sensitivity gradient. Overall, this synthesis highlights the need to account for taxon-dependent sensitivity when evaluating the ecological risks of 2,4-D and provides a basis for improving regulatory frameworks and management of herbicide contamination in freshwater ecosystems.\n\nID: 42526092\nTitle: Multi-omics analysis of the gut-liver axis reveals the health hazards of embryonic egg exposure to zearalenone in chicks.\nAbstract: Zearalenone (ZEN), a widespread Fusarium-derived mycotoxin, poses health risks to animals and humans through contaminated food chains. However, its transgenerational effects following embryonic egg exposure on avian development and chick health remain poorly characterized.This study employed embryonic egg injection and multi-omics approaches to evaluate the impacts of ZEN (0, 5, 50, or 500 \u03bcg/egg) administered to Hy-line Brown eggs on day 5 of incubation. ZEN exposure significantly decreased hatchability and initial chick weight. During the 20-day post-hatch period, it induced dose-dependent reductions in net weight, average daily gain, and average daily feed intake, while increasing the feed conversion ratio.Histopathology showed intestinal inflammation and structural damage, coupled with gut microbiota dysbiosis, notably an elevated abundance of pathogenic bacteria such as Escherichia coli. ZEN also caused liver injury, manifested by elevated serum biochemical indices, oxidative stress, and inflammatory responses. Hepatic metabolomics revealed pronounced alterations in metabolites and pathways associated with lipid metabolism, autophagy, and antioxidant defense.Correlation analyses indicated interconnections between gut microbiota dysbiosis and hepatic metabolic disturbances, suggesting mediation of ZEN developmental toxicity via the gut-liver axis. These results elucidate novel mechanisms of ZEN embryotoxicity and underscore the need to control ZEN contamination in poultry production.\n\nID: 42526085\nTitle: Ferroptosis-associated ALOX12 suppresses ovarian cancer progression through MAPK signaling pathway.\nAbstract: Ovarian cancer (OC) persists as a highly fatal gynecologic tumor, underscoring the urgent need for dependable diagnostic markers and innovative therapeutic strategies. In this study, we identify Arachidonate 12-lipoxygenase (ALOX12) as a previously unrecognized ferroptosis-related tumor suppressive regulator with significant diagnostic and prognostic value in OC. By integrating Weighted Gene Co-expression Network Analysis (WGCNA), machine learning algorithms, and survival modeling, and validating our findings through in vitro and in vivo experiments, transcriptomic profiling, and biochemical assays, we systematically characterized the biological and mechanistic roles of ALOX12. Our analysis revealed that ALOX12 is markedly downregulated in OC tissues, with its low expression correlating with poor clinical outcomes. Functional experiments further demonstrated that ALOX12 suppresses OC cell proliferation, invasion, and migration, while promoting apoptosis and ferroptosis-associated lipid peroxidation. Mechanistically, transcriptome sequencing and protein assays pinpointed MAPK signaling as a key pathway modulated by ALOX12. Additionally, our experiments revealed that ALOX12 exerts its effects by regulating HSPA6 expression. Collectively, these findings highlight ALOX12 as a promising biomarker and potential therapeutic target, offering new insights into ferroptosis-associated signaling networks and their implications for improving the management of OC.\n\nID: 42526057\nTitle: Dysregulated Iron Metabolism In Remodeling of Aging Asthmatic Human Airways.\nAbstract: Iron is essential for cellular function, and lung cells are no exception. Previous studies have demonstrated an association between increased level of iron in the lung and aging and age-related lung diseases including pulmonary fibrosis and asthma in the elderly (AIE). However, the mechanisms underlying the accumulation of iron with aging or AIE, or the cell types involved, remain understudied. In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling.\n\nID: 42525666\nTitle: Correction to \"Dendrobium nobile Lindl polysaccharides attenuate UVB-induced photodamage by regulating oxidative stress, inflammation and MMPs expression in mice model\".\nAbstract: \n\nID: 42525549\nTitle: Association between oxidative balance score and gallstone risk and gallbladder surgery: A cross-sectional study.\nAbstract: ObjectiveTo examine the association between oxidative balance score and the risks of gallstones and gallbladder surgery in US adults, addressing the lack of reliable oxidative stress-related indicators for gallstone prediction.MethodsA cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey 2017-2020. Multivariate logistic regression, subgroup analyses, and smoothed curve fitting models were applied to investigate the relationship between oxidative balance scores and gallstone outcomes, adjusting for age, sex, race, and health conditions.ResultsHigher oxidative balance score was significantly associated with lower risks of gallstones and gallbladder surgery. Each 1-unit increase in the oxidative balance score corresponded to a 2.6% reduction in gallstone risk (odds ratio\u2009=\u20090.974; 95% confidence interval: 0.958, 0.990) and a 3.3% reduction in gallbladder surgery risk (odds ratio\u2009=\u20090.967; 95% confidence interval: 0.950, 0.983). Subgroup and dose-response analyses confirmed these consistent, negative associations.ConclusionsHigher oxidative balance score is independently associated with a reduced prevalence of gallstones and gallbladder surgery. Furthermore, maintaining a higher antioxidant status may play a role in the management of gallstone disease risk.\n\nID: 42525531\nTitle: High Glucose Supplementation Aggravates Experimental Autoimmune Epididymo-orchitis via Localized Th17 Skewing in the Male Reproductive Tract.\nAbstract: Chronic epididymo-orchitis contributes significantly to male infertility through immune cell infiltration and pro-inflammatory cytokine elevation. High glucose intake promotes Th17 differentiation and autoimmunity, but its effects on autoimmune testicular inflammation remain unclear. To determine whether chronic high glucose supplementation exacerbates experimental autoimmune epididymo-orchitis (EAEO), impairs spermatogenesis, and drives CD4+ T-cell dysregulation, particularly Th17 polarization, in the reproductive tract. EAEO was induced in male C57BL/6 mice with or without chronic 10% glucose supplementation in drinking water. Sperm parameters, ROS levels, apoptosis, and histopathology were evaluated. CD4+ T-cell subsets (Th1, Th17, Treg, TNF-\u03b1+ effector memory) were quantified by flow cytometry in testis, epididymis, spleen, and testicular inguinal lymph nodes (iLN) at days 30, 60, and 90 post-immunizations. High glucose intake accelerated EAEO progression, markedly worsening sperm concentration and motility, elevating sperm ROS, increasing germ cell apoptosis, and causing severe histopathological damage. In the reproductive tract, glucose induced an upward trend of CD4+ T cells and late-phase selective Th17 skewing (days 60-90), with significant IL-17A+CD4+ Teff increases and accompanying TNF-\u03b1+CD4+CD44+ Teff upregulation, while IFN-\u03b3+ Th1 responses remained modest. These pro-inflammatory changes were strictly localized, with no significant Th17, Th1, Treg, or TNF-\u03b1 alterations in spleen or iLN. Chronic high glucose exacerbates EAEO by intensifying oxidative stress, apoptosis, and tissue injury while promoting a late-phase, tissue-restricted Th17-biased CD4+ T-cell response in the testis and epididymis. These findings reveal a metabolic-immune axis that may accelerate immune-mediated male subfertility via localized Th17 mechanisms.\n\nID: 42525507\nTitle: An expanded apolipoprotein D family provides spider mites with dual-layer protection against dietary oxidative stress.\nAbstract: Plant defense has driven the evolution of species-dependent adaptive strategies in many herbivores, but the molecular mechanisms of adaptation in most arthropods remain largely unknown. The two-spotted spider mite (Tetranychus urticae) is a generalist herbivore that feeds by sucking the contents of mesophyll cells, a feeding strategy distinct from that of phloem-feeding insects. Here, we show the unexpected differential expression of apolipoprotein D (ApoD) genes during feeding when mites are transferred to different host plant species, as well as extreme gene family expansion (64 ApoD paralogs, the largest reported in any organism). We find that ApoD proteins protect mites against reactive oxygen species (ROS) during feeding, and we identify a dual-layer mechanism by which ApoD proteins counteract plant ROS defenses during ingestion and digestion. First, the salivary protein TuApoD2 is secreted during the ingestion of mesophyll cell contents, where it interacts with glycolate oxidase 2 (GOX2) to inhibit H2O2 generation. After ingestion, TuApoD33 in the gut cells also interacts with GOX2 to maintain the inhibition of H2O2 generation. These findings suggest that the evolutionary expansion of the ApoD gene family is a key component of the molecular arms race between herbivorous mites and host plants.\n\nID: 42525501\nTitle: Altered Distribution of CD14+ Macrophages and Reduced ROS Activity in Preeclamptic Placentas.\nAbstract: Pregnancy requires a delicate balance between maternal immune tolerance and protective responses, with macrophages playing a pivotal role in placental development and immune regulation. Preeclampsia, a hypertensive disorder that affects 5%-8% of pregnancies, is associated with immune dysregulation, oxidative stress, and impaired placental remodeling. In this study, we investigated the distribution of CD14+ and CD11b+ cells and the production of reactive oxygen species (ROS) in placental tissues from healthy pregnancies and preeclampsia cases, from areas near the umbilical cord and the delivery channel and divided into maternal, maternal/fetal and fetal zones, of each area. Immunofluorescence analysis revealed that in healthy placentas, CD14+ macrophages were heterogeneously distributed with enrichment in the fetal section near the delivery channel, whereas in preeclamptic placentas these cells accumulated predominantly in the umbilical cord region. No significant differences were observed for CD11b+ cells, although a tendency toward increased numbers was noted in preeclamptic tissues. ROS analysis showed no statistically significant changes, but preeclamptic placentas exhibited weaker fluorescence intensity, indicating reduced ROS activity. These findings suggest that altered CD14+ and CD11b+ cells localization, together with diminished ROS signaling, may contribute to the pathophysiology of preeclampsia by impairing immune regulation and placental vascular remodeling.\n\nID: 42525467\nTitle: Specific neurotoxicity of local anaesthetics revisited: An evidence-based narrative review.\nAbstract: Local anaesthetics are essential to regional anaesthesia but may exert neurotoxic effects on peripheral nerves under specific conditions. Although perioperative nerve injury is increasingly recognised, the contribution of local-anaesthetic neurotoxicity, the relative toxicity of different agents and concentrations, and the influence of patient-related risk factors remain incompletely defined. This evidence-based narrative review synthesises experimental and clinical data on peripheral nerve neurotoxicity associated with local anaesthetics and discusses implications for clinical practice and future research. A prospectively registered search was conducted across major biomedical databases for studies published between 1990 and 2024. Experimental evidence consistently demonstrates dose-dependent and time-dependent neurotoxicity for all clinically used local anaesthetics, characterised by ultrastructural damage, oxidative stress, mitochondrial dysfunction and activation of apoptotic and intracellular signalling pathways. Relative toxicity varies between agents and concentrations, with lidocaine and bupivacaine often appearing more potent than ropivacaine or chloroprocaine in preclinical models, while findings for articaine remain heterogeneous. Diabetic and metabolically compromised nerves exhibit increased susceptibility, supporting a 'two-hit' model of injury. In contrast, clinical evidence directly linking specific agents, concentrations or exposure durations to permanent peripheral nerve injury is limited, and such injuries are typically multifactorial. Overall, chemical neurotoxicity should be considered one component of a broader perioperative risk profile. Risk mitigation should prioritise avoidance of intraneural injection, adherence to recommended doses and cautious use of high concentrations or prolonged exposure, particularly in vulnerable nerves. Further research should integrate mechanistic and clinical outcomes while accounting for patient-level risk factors.\n\nID: 42525347\nTitle: KLF4 in Parkinson's Disease: Decoding the Molecular Puzzle of Neuroinflammation, Oxidative Stress, and Emerging Therapies.\nAbstract: Parkinson's disease (PD) is the most prevalent neurodegenerative movement condition. Tremors, stiffness, bradykinesia/akinesia, and postural instability are its primary motor symptoms; nevertheless, the clinical features also include non-motor and additional motor symptoms. Kr\u00fcppel-like factor 4 (KLF4), a zinc finger transcription factor, is present in several human tissues and performs a range of cell-dependent regulatory actions. Various neurological diseases, such as PD, Alzheimer's disease (AD), and Huntington's disease (HD), have been linked to KLF4, which regulates some neurophysiological and neuropathological processes in the brain. Recent data indicate that KLF4 plays a crucial regulatory role in the neurophysiological and neuropathological processes underlying PD, suggesting that it might be a viable therapeutic target for neurodegenerative diseases. This review focuses on the potential molecular mechanism underlying KLF4-mediated neuroinflammation, oxidative stress, mitochondrial dysfunction, and apoptosis. KLF4-mediated pathways are clarified by the information gathered here, and targeting them appears to be a viable therapeutic strategy for treating PD. Nevertheless, there is insufficient information on this subject, and more investigations are needed to fully understand the translational significance of the KLF4-oriented therapeutic strategy in PD.\n\nID: 42525318\nTitle: Arbutin mediated neuroprotection in zebrafish model of traumatic brain injury via modulating Nrf2/NF-\u03baB pathway.\nAbstract: Traumatic Brain Injury (TBI) is a major cause of mortality and disability worldwide and is associated with oxidative stress, neuroinflammation, and neurotransmitter imbalance. Arbutin, a naturally occurring glycoside with known antioxidant and anti-inflammatory properties, has the potential to modulate neurochemical alterations following brain injury. The present study was designed to evaluate the neuroprotective effects of arbutin in a zebrafish model of TBI induced by a novel non-invasive mechanical impact method termed \"force-induced TBI.\" Adult zebrafish were randomly divided into seven groups (n\u2009=\u200914 per group): normal control, TBI control, arbutin per se, arbutin-treated groups (25, 50, and 100\u00a0mg/kg, i.p.), and a co-treatment group receiving arbutin (100\u00a0mg/kg) co-administrated with chrysin (25\u00a0mg/kg), a known modulator of the Nrf2/NF-\u03baB signaling pathway. Behavioural assessments, including the open field test, novel tank diving test (NTDT), T-maze, and novel object recognition test (NORT), were conducted on days 1, 4, and 7 to evaluate locomotion activity, anxiety-like behaviour, spatial memory, and recognition ability, respectively. Following behavioural evaluation, brain tissues were analysed for oxidative stress markers (MDA, nitrite, GSH, and SOD), neurotransmitter levels (GABA and glutamate), pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, and IL-6), and histopathological alterations. Immunohistochemical analysis of Nrf2 and NF-\u03baB was also performed. The results demonstrated that arbutin significantly improved behavioural performance, restored oxidative balance, normalized neurotransmitter levels, and attenuated neuroinflammatory responses. Furthermore, arbutin treatment was associated with increased Nrf2 immunoreactivity and reduced NF-\u03baB immunoreactivity in a dose-dependent manner. The co-treatment with chrysin also exhibited protective effects, supporting its potential modulatory role in oxidative stress and these effects are associated with modulation of oxidative stress, neuroinflammation, neurotransmitter imbalance, and Nrf2/NF-\u03baB immunoreactivity. These findings suggest that arbutin possesses neuroprotective potential against secondary brain injury and is associated with modulation of oxidative stress, inflammatory responses, and Nrf2/NF-\u03baB immunoreactivity.\n\nID: 42525317\nTitle: Rutin as a multi-target anti-inflammatory phytochemical in arthritic disorders: pharmacological mechanisms and therapeutic potential.\nAbstract: Rutin, a bioactive flavonoid widely present in medicinal plants such as Fagopyrum esculentum, Ruta graveolens, and citrus species, has been traditionally used for inflammatory conditions, including joint disorders. Despite its long-standing ethnomedicinal use, a comprehensive mechanistic understanding of its role across different types of arthritis remains limited. This review aims to systematically evaluate the pharmacological effects and molecular mechanisms of rutin in rheumatoid arthritis, gouty arthritis, osteoarthritis, and Psoriasis, integrating ethnopharmacological relevance with modern experimental evidence. A comprehensive literature search was conducted across databases including PubMed, Scopus, and Web of Science. Preclinical in vivo, in vitro, and mechanistic studies investigating rutin in arthritic models were included. Data were synthesized to identify key molecular targets, signaling pathways, and therapeutic outcomes. Rutin demonstrated significant anti-arthritic effects across multiple models. In rheumatoid arthritis, rutin reduced inflammatory cytokines (TNF-\u03b1, IL-6), oxidative stress, and joint damage via inhibition of NF-\u03baB and iNOS signaling. In gout, rutin lowered uric acid levels by inhibiting xanthine oxidase and suppressing NLRP3 inflammasome activation. In osteoarthritis, rutin protected cartilage integrity by modulating extracellular matrix degradation and regulating NF-\u03baB/MAPK, SIRT1, and RhoA/ROCK pathways. In Psoriasis, rutin attenuated keratinocyte proliferation and inflammation through JAK/STAT inhibition and activation of the Nrf2 antioxidant pathway. Additionally, advanced delivery systems such as nanoparticles and hydrogels enhanced its bioavailability and therapeutic efficacy. Rutin exhibits multi-target anti-arthritic potential supported by both traditional use and modern pharmacological evidence. Its ability to modulate key inflammatory and oxidative pathways highlights its potential as a phytopharmaceutical candidate for arthritis management. Further clinical validation and standardization are required to translate these findings into therapeutic applications.\n\nID: 42525304\nTitle: Chlorpyrifos-induced toxicity in scenedesmus sp. t24 and synechococcus sp. d24.\nAbstract: The widespread use of chlorpyrifos, an organophosphate insecticide, raises concerns regarding its impact on non-target aquatic organisms. This study evaluated the toxicological responses of Synechococcus sp. D24 and Scenedesmus sp. T24 exposed to chlorpyrifos at 0.01-10\u00a0mg/L. Growth inhibition, chlorophyll a content, photosynthetic efficiency (Fv/Fm), and superoxide dismutase (SOD) activity were assessed to determine physiological stress. Scenedesmus sp. T24 showed high sensitivity, exhibiting strong reductions in growth, chlorophyll a, and Fv/Fm even at low concentrations, accompanied by a continual decline in SOD activity. In contrast, Synechococcus sp. D24 demonstrated greater tolerance, with moderate physiological alterations and a biphasic SOD response indicating possible adaptation at low exposure levels. The EC\u2085\u2080 values (0.95\u00a0\u00b5g/L and 9.5\u00a0\u00b5g/L, respectively) confirmed clear species-specific differences. These results highlight the ecological risks of chlorpyrifos contamination and support the use of microalgae as sensitive bioindicators in aquatic toxicology and environmental monitoring.\n\nID: 42525297\nTitle: Norcantharidin attenuates amiodarone-induced pulmonary fibrosis via modulating miRNA-30a/GSK-3\u03b2/\u03b2-catenin and oxidative-inflammatory pathways.\nAbstract: Amiodarone-induced pulmonary fibrosis (AIPF) is characterized by inflammation, oxidative stress, microRNA dysregulation, fibroblast activation, and excessive extracellular matrix deposition. Norcantharidin (NCTD), a small-molecule compound with reported anti-inflammatory, antioxidant, and antifibrotic properties, has attracted attention as a potential therapeutic agent. To investigate the protective effects of NCTD against AIPF in rats. Eighteen rats were randomly divided into three groups (n\u2009=\u20096 each): a negative control group receiving vehicle, an amiodarone group, and an NCTD-treated group receiving 0.1\u00a0mg/kg intraperitoneally for six weeks. Pulmonary fibrosis was induced by oral administration of 50\u00a0mg/kg amiodarone for five weeks. Lung injury was assessed using hematoxylin and eosin staining and semi-quantitative scoring, collagen deposition was evaluated by Masson's trichrome staining, and immunohistochemistry was performed for fibronectin and \u03b1-smooth muscle actin (\u03b1-SMA). Molecular and biochemical markers including tumor necrosis factor (TNF)-\u03b1, \u03b2-catenin, interleukin (IL)-1\u03b2, malondialdehyde (MDA), and glutathione (GSH) were measured, while glycogen synthase kinase (GSK)-3\u03b2 was assessed by Western blot, and miRNA-30a by quantitative PCR. Amiodarone significantly increased lung injury scores, collagen deposition, \u03b1-SMA, fibronectin, TNF-\u03b1, IL-1\u03b2, MDA, GSK-3\u03b2, and \u03b2-catenin, while reducing GSH and miRNA-30a levels. NCTD treatment markedly reversed these alterations, restoring \u03b1-SMA, fibronectin, TNF-\u03b1, IL-1\u03b2, MDA, GSK-3\u03b2, and \u03b2-catenin, while increasing GSH and miRNA-30a toward normal. Histologically, NCTD preserved alveolar architecture, reduced peribronchiolar inflammation, and normalized collagen distribution. These results demonstrate that NCTD exerts potent antifibrotic, anti-inflammatory, and antioxidant effects in AIPF, likely through modulation of oxidative stress, inflammatory cytokines, microRNA expression, and the GSK-3\u03b2/\u03b2-catenin signaling pathway, highlighting its potential as a therapeutic agent for drug-induced lung injury.\n\nID: 42525295\nTitle: Integrated bioinformatics and experimental validation reveal that kaempferol ameliorates intervertebral disc degeneration via dual anti-inflammatory and anti-aging pathways.\nAbstract: Intervertebral disc degeneration (IVDD) is a degenerative disease characterized by degradation of the extracellular matrix (ECM) in the nucleus pulposus, disruption of the fibrous ring structure, and imbalance of the inflammatory microenvironment. It is the main cause of chronic low back pain. Its pathogenesis is closely related to cellular aging and immune inflammation. Aging nucleus pulposus cells release pro-inflammatory factors such as IL-6 and TNF-\u03b1 through the secretion of senescence associated secretory phenotype (SASP), recruiting M1 macrophages to infiltrate and forming a vicious cycle of \"aging inflammation matrix destruction.\" This study systematically analyzed the molecular mechanism by which kaempferol improves IVDD through multi-target regulation by integrating bioinformatics analysis, animal experiments, and cell models. Bioinformatics screening revealed significant abnormal expression of genes such as AURKB, CCNB1, AXL, NEK6, and PTK2 in IVDD degenerated tissues. Downregulation of CCNB1 induced G2/M phase arrest by inhibiting CDK1 activity, while activation of GSK3B inhibited the Wnt signaling pathway by phosphorylating \u03b2-catenin, exacerbating ECM catabolism. Proteomics further confirms that the NOX4 mediated ROS-p38 MAPK pathway promotes cell apoptosis and SASP secretion. Immune infiltration analysis showed that M1 macrophages were significantly enriched in degenerated intervertebral discs, and their secreted IL-6 and TNF-\u03b1 amplified the inflammatory cascade by activating the NF-\u03ba B pathway. Animal experiments have shown that intervention with kaempferol can partially restore the intervertebral disc height index (DHI), downregulate the levels of IL\u20111\u03b2 and TNF\u2011\u03b1, upregulate the expression of CCNB1 and AURKB (which were downregulated in the IVDD model), thereby alleviating G2/M phase arrest and promoting cell cycle progression, inhibit AXL and PTK2, and reduce macrophage infiltration. Mechanistically, kaempferol inhibits NOX4 activity by clearing ROS, blocking the vicious cycle of oxidative stress\u2011inflammation; by regulating the NEK6/NF\u2011\u03baB axis, the expression of MMP\u20113 and ADAMTS\u20114 is reduced, delaying ECM degradation; and improve the immune microenvironment by promoting macrophage polarization towards the M2 phenotype. In addition, kaempferol can reverse the metabolic imbalance mediated by GSK3B. This study reveals for the first time that kaempferol upregulates core gene networks such as AURKB and CCNB1 while suppressing AXL through the \"anti\u2011inflammatory anti\u2011aging\" dual pathway, thereby breaking the \"aging\u2011immunity\" crosstalk and restoring cell cycle homeostasis, providing a new strategy for natural compound intervention in IVDD treatment.\n\nID: 42525287\nTitle: Rutin attenuates acrylamide-induced oxidative liver injury.\nAbstract: Acrylamide (ACR) is an important chemical raw material, and its toxic effects have been confirmed in vitro and in vivo. However, only a few studies have investigated ACR-induced liver injury. As a naturally occurring flavonoid widely distributed across the plant kingdom, rutin (Rut) possesses notable pharmacological properties. This study aimed to demonstrate its therapeutic potential in mitigating ACR-induced hepatic injury in rats. Accordingly, an intervention model was established to explore the mechanistic basis of the protective effects of Rut against ACR-induced liver injury. The experimental design comprised five cohorts (n\u2009=\u200910), consisting of 50 male Sprague-Dawley rats randomly assigned to each group: (1) Control (0.5% CMC-Na\u2009+\u2009ddH2O), (2) ACR (20\u00a0mg/kg/day via gavage), (3) Rut-L (100\u00a0mg/kg)\u2009+\u2009ACR, (4) Rut-M (200\u00a0mg/kg)\u2009+\u2009ACR, and (5) Rut-H (400\u00a0mg/kg)\u2009+\u2009ACR. Interventions lasted for 21 days. The body weights of the animals were monitored daily. The liver coefficient (liver weight/body weight) was calculated after euthanasia. Commercial assay kits were used to determine serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities and hepatic Superoxide Dismutase (SOD), Glutathione (GSH), and Malondialdehyde (MDA) levels. Histopathological changes were assessed using Hematoxylin and eosin and Masson staining. Tumor Necrosis Factor-\u03b1 (TNF-\u03b1) and cleaved caspase-3 expression levels were analyzed using immunohistochemistry. Compared with the Control group, ACR exposure attenuated the rate of body weight accrual (P\u2009<\u20090.05) and the liver-to-body weight ratio (P\u2009<\u20090.05), elevated serum ALT (\u219134.8%, P\u2009<\u20090.05) and AST (\u219147.7%, P\u2009<\u20090.05), decreased hepatic SOD (\u219348.9%, P\u2009<\u20090.05) and GSH (\u219317.7%, P\u2009<\u20090.05), and increased MDA (\u219138.8%, P\u2009<\u20090.05). High-dose Rut reversed these effects by increasing body weight gain (P\u2009<\u20090.01), liver coefficient (\u219129.4%, P\u2009<\u20090.05), SOD (\u219132.1%, P\u2009<\u20090.05), and GSH (\u219112.1%, P\u2009<\u20090.05), while reducing ALT (\u219322.9%, P\u2009<\u20090.01), AST (\u219316.8%, P\u2009<\u20090.01), and MDA (\u21939.0%, P\u2009<\u20090.05) levels. Histopathological analysis demonstrated reduced hepatocyte necrosis and collagen deposition in the Rut-treated group. Immunohistochemistry revealed that ACR increased TNF-\u03b1 (\u2191121.4%, P\u2009<\u20090.001) and cleaved caspase-3 (\u219197.8%, P\u2009<\u20090.001) expression, which was suppressed by Rut (TNF-\u03b1: \u219348.2%, P\u2009<\u20090.01; cleaved caspase-3: \u219339.5%, P\u2009<\u20090.01). The effect sizes (Cohen's d) ranged from 1.2 to 3.6, indicating robust effects. Rut exhibits a marked protective effect against ACR-induced hepatic injury. Therefore, Rut may be considered a potential agent for preventing ACR-induced liver injury in rats.\n\nID: 42525230\nTitle: Effects of Acute Hypoxic Exposure on Ovarian Function in Female Mice.\nAbstract: To investigate the effects of acute high-altitude hypoxia on ovarian function and ovarian tissue transcriptomics in female mice, providing experimental evidence for elucidating the mechanisms underlying female reproductive damage caused by acute high-altitude hypoxia. Sixty female mice were randomized into three groups (20 mice each): control (CON, 500\u00a0m, conventional housing for 14 d), 7 d hypoxic exposure (LO1) and 14 d hypoxic exposure (LO2). LO1 and LO2 were kept in a low-pressure hypoxic chamber simulating 5500\u00a0m. Serum reproductive hormones (AMH, FSH, LH, E2) and oxidative stress markers were detected; ovarian indices were calculated and ovarian histopathology examined. Additionally, transcriptome sequencing and functional enrichment analysis of differentially expressed genes were conducted on ovarian tissues. Compared with CON, LO1 and LO2 showed markedly decreased serum AMH, LH and E2 (P\u2009<\u20090.01), sharply elevated FSH (P\u2009<\u20090.001), increased malondialdehyde (P\u2009<\u20090.001), reduced superoxide dismutase activity (P\u2009<\u20090.01), first increased then decreased total antioxidant capacity (P\u2009<\u20090.001), and lower ovarian index (P\u2009<\u20090.01). Histology showed ovarian atrophy and ischemic congestion, with fewer primary, secondary and mature follicles (P\u2009<\u20090.05) and more atretic follicles in LO2 (P\u2009<\u20090.05). Transcriptome sequencing found 234 significantly differentially expressed genes, whose co-differentially expressed ones were enriched in oxygen transport/oxidative stress and steroid hormone synthesis pathways. Acute high-altitude hypoxia impairs ovarian reserve function and disrupts follicular development in female mice, potentially through oxidative stress imbalance and dysregulation of genes involved in steroid hormone synthesis pathways.\n\nID: 42525168\nTitle: Celastrol attenuates synovial inflammation and experimental arthritis by modulating PTGS2-associated ferroptosis resistance in fibroblast-like synoviocytes.\nAbstract: Rheumatoid arthritis (RA) is characterized by persistent synovial inflammation and aggressive activation of fibroblast-like synoviocytes (FLS). Celastrol has recognized anti-inflammatory activity, but its mechanism in RA remains incompletely defined. This study investigated whether the anti-arthritic effect of celastrol is associated, at least in part, with a PTGS2-associated ferroptosis-resistance pathway in FLS. Potential targets of celastrol in RA were identified through integrated bioinformatic analyses. Collagen-induced arthritis (CIA) rats and primary FLS were used to evaluate the effects of celastrol in vivo and in vitro. Joint pathology, inflammatory mediator expression, oxidative stress, iron accumulation, lipid peroxidation, and ferroptosis-related proteins were assessed. Loss- and gain-of-function experiments were performed to examine the functional role of PTGS2. Bioinformatic screening identified PTGS2 as a candidate functional mediator linking celastrol to RA. In CIA rats, celastrol reduced paw swelling, arthritis severity, synovial hyperplasia, inflammatory cell infiltration, and cartilage and bone destruction. In FLS, celastrol suppressed cell proliferation and migration and decreased the expression of pro-inflammatory cytokines. Mechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment. PTGS2 expression was markedly elevated in RA models and was downregulated by celastrol. PTGS2 overexpression attenuated the anti-inflammatory effects of celastrol and reversed several ferroptosis-associated changes, supporting a functional role for PTGS2 in this process. Celastrol alleviates synovial inflammation and experimental arthritis, at least in part, in association with PTGS2 modulation and attenuation of a ferroptosis-resistant phenotype in FLS. To our knowledge, these findings provide experimental evidence linking celastrol, PTGS2-associated regulation, and ferroptosis resistance in RA models.\n\nID: 42525154\nTitle: L-Arginine effectively alleviates doxorubicin-induced cardiac dysfunction by inhibiting myocardial fibrosis.\nAbstract: The clinical use of doxorubicin (DOX), a widely used and effective antitumor drug, is limited by its cardiotoxicity. Currently, safe and effective strategies for preventing doxorubicin-induced cardiotoxicity (DIC) remain limited. Therefore, this study aimed to investigate the potential cardioprotective effects and possible underlying mechanisms of L-arginine (L-Arg) against DIC. To investigate the cardioprotective effects and underlying mechanisms of L-Arg, three complementary experimental models were used: male Sprague-Dawley rats (n\u2009=\u20096 per group), male AMPK\u03b12 knockout (AMPK\u03b12 KO) mice (n\u2009=\u20096 per group), and H9c2 cardiomyocytes. A DIC model was induced in rats by intraperitoneal injection of DOX (2.5\u00a0mg/kg/week) for 6 weeks. Serum nitric oxide (NO) and lactate dehydrogenase (LDH) levels were measured to assess oxidative stress and myocardial injury. Cardiac morphology, inflammation, and fibrosis were evaluated by histological staining and protein expression analyses, whereas miR-29b-3p expression was determined by RT-qPCR. AMPK\u03b12-deficient models and miR-29b-3p gain- and loss-of-function models were used to investigate the underlying mechanisms. Compared with the DOX group, L-Arg significantly improved cardiac function and morphology, reduced oxidative stress, myocardial injury, inflammation, and fibrosis, and increased miR-29b-3p expression (all P\u2009<\u20090.05). Moreover, miR-29b-3p overexpression enhanced, whereas miR-29b-3p inhibition attenuated, the cardioprotective effects of L-Arg (all P\u2009<\u20090.05). These protective effects were also markedly attenuated by AMPK\u03b12 deficiency (P\u2009<\u20090.05). L-Arg alleviates DIC by improving cardiac function, reducing oxidative stress, inflammation, and fibrosis, and increasing miR-29b-3p expression. These cardioprotective effects are associated with AMPK\u03b12 activation and enhanced miR-29b-3p expression.\n\nID: 42525146\nTitle: NSAIDs in the environment: a 2020-2025 review of impacts on plant and algal Physiology.\nAbstract: Non-steroidal anti-inflammatory drugs (NSAIDs) belong to the most frequently detected pharmaceutical pollutants in aquatic ecosystems, raising growing concern about their effects on non-target primary producers. Unlike earlier reviews, based mainly on data collected before the year 2020, when environmental exposure levels were substantially lower, this work synthesizes research conducted over the last five years (2020-2025), a period that includes the SARS-CoV-2 pandemic. The pandemic was associated with a sharp global increase in the consumption of NSAIDs, resulting in their markedly elevated environmental loads. Consequently, the studies assessed in this review reflect plant and algal responses under significantly higher contamination pressures than those reported in pre-pandemic decades, offering a new perspective on their phytotoxic potential. A systematic literature search retrieved over 5,000 records, from which the most relevant experimental studies were selected for detailed evaluation. The compiled evidence demonstrates that NSAIDs adversely affect photosynthesis, induce ultrastructural damage to chloroplasts, and compromise mitochondrial respiration, including alterations in membrane potential and ATP production. Exposure to NSAIDs triggers oxidative stress responses, characterized by reactive oxygen species overproduction, lipid peroxidation, and variable changes in antioxidant enzyme activity. Beyond primary metabolism, numerous reports document disruptions in growth patterns, root system architecture, mineral balance, and secondary metabolite biosynthesis. By integrating the most up-to-date findings from a period of exceptionally intense pharmaceutical pollution, this review provides a novel and more realistic assessment of the ecological risks posed by NSAIDs. It underscores the urgency of developing stricter environmental quality standards and highlights key directions for future research under contemporary contamination scenarios.\n\nID: 42524981\nTitle: Time-dependent protective effects of syringic acid following testicular torsion-detorsion: an experimental rat model.\nAbstract: To investigate the protective effects of syringic acid (SA) against testicular ischemia-reperfusion (I/R) injury during different reperfusion periods in an experimental rat model. Forty-eight male Wistar albino rats were randomly assigned to six groups: control, sham, torsion/detorsion (T/D) 4 h, T/D + SA 4 h, T/D 24 h, and T/D + SA 24 h. Testicular torsion was induced by 720\u00b0 rotation of the left testis for 2 h, followed by detorsion and 4 or 24 h reperfusion. SA (10 mg/kg) was administered intraperitoneally 30 min before detorsion. Oxidative stress markers, histopathological alterations, and immunohistochemical expressions of apoptotic protease activating factor-1 (APAF-1) and inducible nitric oxide synthase were evaluated. T/D significantly decreased total antioxidant status and glutathione levels while increasing myeloperoxidase activity and APAF-1/inducible nitric oxide synthase (iNOS) expressions compared with controls (p < 0.001). SA treatment restored antioxidant capacity and attenuated inflammatory and apoptotic responses (p < 0.05). Histopathological analyses demonstrated lower Cosentino scores and higher Johnsen scores in SA-treated groups than in untreated T/D groups (p < 0.05). Malondialdehyde levels showed no significant intergroup differences. SA attenuates testicular I/R injury by reducing oxidative stress, inflammation, and apoptosis while preserving spermatogenic function and histological integrity.\n\nID: 42524884\nTitle: Innovative Test Strip-Based Colorimetric Sensors Integrated With Affinity Chromatography: Acetylcholinesterase Inhibitor Screening Breakthrough in Lycium Barbarum Leaves.\nAbstract: Current Alzheimer's drugs exhibit limited effectiveness, highlighting the necessity for multi-target treatments. This study developed an innovative and efficient screening platform combining hydrogen peroxide test strip-based colorimetric sensing with affinity chromatography for rapid identification of acetylcholinesterase (AChE) inhibitors from complex herbal medicines. Applying this strategy, from Lycium barbarum leaves, we identified three potent inhibitors: chlorogenic acid, N-acetyl-N'-caffeoylputrescine (NANCP), and N-caffeoylputrescine (NCP), with IC50 ranging from 55.7 to 143.2\u00a0\u00b5m. Molecular analyses confirmed their stable binding to AChE. In a D-galactose and AlCl3-induced Alzheimer's disease (AD) mouse model, NCP treatment significantly rescued cognitive deficits in AD mice, with the spontaneous alternation rate in the Y-maze test improved by up to 50%. It markedly reduced cerebral A\u03b2 levels (by 54%) and pro-inflammatory cytokines, including TNF-\u03b1, IL-1\u03b2, and IL-6, alleviated oxidative stress, and attenuated hippocampal neuronal damage. Mechanistically, NCP modulated glycerophospholipid metabolism, reshaped gut microbiota, and targeted the proteasome-autophagy pathway, revealing a multi-faceted synergistic mechanism. The research offers a new screening tool for AChE inhibitors and highlights a promising natural multi-target candidate, NCP, for AD therapy.\n\nID: 42524834\nTitle: Redox-sensitive factors as targets of thiol compounds to hinder SARS-CoV-2 replication and inflammatory response.\nAbstract: SARS-CoV-2 has undergone rapid genetic evolution, leading to the emergence of new variants with distinct mutations impacting global public health. Upon infection, the virus triggers a robust inflammatory response characterized by the release of pro-inflammatory cytokines, which play a central role in lung injury. It also alters the host antioxidant response, causing oxidative stress that supports viral replication and cytokine overproduction. This study investigated key pathogenic effectors in Calu-3 and A549-ACE2/TMPRSS2 cells infected with SARS-CoV-2 variants, focusing on replication kinetics, cellular redox state, and inflammatory cytokine profile. A dramatic redox alteration in terms of glutathione (GSH) and Cysteine (Cys) was observed at 48 h p.i., along with a strong pro-inflammatory cytokine response , likely via activation of the JNK/AP-1 signaling pathway. To counteract these effects, two thiol molecules were tested: I-152, a monothiol conjugate of N-Acetyl-Cysteine (NAC) and \u03b2-mercaptoethylamine (MEA) and its dithiol derivative, I-152SdAc. Thiols restored GSH balance by enhancing the expression of Nrf2-mediated genes, such as glutamate-Cys ligase modifier subunit (GCLM), and counteracted AP-1-mediated pathway, resulting in a significant reduction of inflammation and viral replication. Antiviral and anti-inflammatory activities of thiols were confirmed in NHBE cells. These findings highlight that redox imbalance is a key pathogenetic event in SARS-CoV-2 infection. Notably, besides Nrf2 and AP-1, other redox-sensitive factors, such as the CHAC glutathione-specific gamma-glutamyl-cyclotransferase 1 (CHAC1), seem to contribute to the pathogenesis and may represent a new potential therapeutic target of redox active compounds. Therefore, the thiol-derived molecules act as broadly effective compounds by limiting virus replication and inflammation.\n\nID: 42524713\nTitle: Stage-Adaptive Janus Microneedle System for Redox-Immune Regulation and Mitochondrial Protection in Infected Diabetic Wound Healing.\nAbstract: Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia-driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage-adaptive Janus microneedle patch (MN-FeSAC-PPE) to enable a staged therapeutic process from early antibacterial intervention to subsequent redox-immune microenvironment remodeling and regenerative tissue repair. This stage-adaptive design integrates Fe single-atom nanozymes (Fe-SACs) into the microneedle base to rapidly kill bacteria using near-infrared light, which activates reactive oxygen species (ROS) production, enabling rapid antibacterial activity against wound pathogens. Meanwhile, propolis extract-loaded (PPE) tips deliver antioxidant bioactive compounds into the wound bed to mitigate oxidative stress, modulate the redox-immune microenvironment, and support the inflammatory-to-regenerative transition. In vitro, MN-FeSAC-PPE enhanced antioxidant defense, suppressed pro-inflammatory factors, and protected fibroblasts from oxidative stress-induced mitochondrial dysfunction. Transcriptomic analysis further supported reduced inflammatory signaling and enhanced metabolism-related programs. In S. aureus-infected diabetic wounds, NIR-activated MN-FeSAC-PPE accelerated wound closure, promoted angiogenesis and collagen remodeling, and alleviated inflammation. These findings establish a stageadaptive redox-immune and bioenergetic regulatory microneedle platform for infected diabetic wound repair.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse.\n  --- END ACTUAL ABSTRACT FOR 42403480 ---\n\n- ERROR: You cited ID: 42320701 for the quote: \"Spinal cord I/R injury induced significant neurological deficits, ferroptosis... lipid peroxidation, and inflammation.

Ferroptosis, an iron-dependent form of regulated cell death, contributes significantly to this pathology. This study investigates the hypothesis that miR-10a-5p attenuates spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. A spinal cord I/R injury model was established in male Sprague-Dawley male rats via transient aortic occlusion. Intrathecal injections of the ferroptosis inhibitor Liproxstatin-1 (Lip-1), siRNA targeting ACSL4 or TAK1, and miR-10a-5p agomir/antagomir were administered prior to ischemia induction. Neurological function was assessed using Tarlov scores. Histopathological changes were evaluated by H&E, Nissl, and immunofluorescence staining. Mitochondrial ultrastructure was examined by transmission electron microscopy (TEM). Expression levels of ferroptosis-related markers (ACSL4, GPX4, COX2, FTH1), inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and lipid peroxidation products (MDA, 12-HETE, 15-HETE, LPO) were measured using Western blot, qPCR, and ELISA. The targeting relationship between miR-10a-5p and TAK1 was validated by dual-luciferase reporter assay. Spinal cord I/R injury induced significant neurological deficits, ferroptosis (evidenced by increased iron, MDA, ACSL4, and COX2; decreased GPX4 and GSH), lipid peroxidation, and inflammation. Lip-1 treatment ameliorated these changes. Knockdown of ACSL4 or TAK1 similarly inhibited ferroptosis, reduced inflammation, and improved motor function. Spinal cord I/R injury induced significant downregulation of miR-10a-5p. It directly targeted TAK1, as confirmed by luciferase assay. Consequently, miR-10a-5p overexpression suppressed TAK1/ACSL4 axis, mitigated lipid peroxidation and ferroptosis, and reduced pro-inflammatory cytokine levels (TNF-\u03b1 and IL-1\u03b2), leading to improved neurological outcomes. This study demonstrates that miR-10a-5p plays a protective role in spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. These findings highlight the potential of the miR-10a-5p/TAK1/ACSL4 axis as a novel therapeutic target for preventing and treating spinal cord I/R injury.\n  --- END ACTUAL ABSTRACT FOR 42320701 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time.\" (Source: 42519304)\n- \"Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index.\" (Source: 42519304)\n- \"Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways.\" (Source: 42519304)\n- \"However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI.\" (Source: 42519304)\n- \"Rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation.\" (Source: 42341849)\n- \"These findings provide the first evidence that ACSL4-mediated ferroptosis is a key driver of acute spinal motor neuron injury following CA.\" (Source: 42341847)\n- \"We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis.\" (Source: 42317798)\n- \"Ninjurin1 (NINJ1) is a cell-surface molecule that has gained considerable attention for its role in mediating plasma membrane rupture (PMR).

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]\nThe claim that coordinate activation of lytic cell death programs (ferroptosis, pyroptosis, and necroptosis) in response to spinal cord injury is mediated by metabolic modulation of CD14, suggesting that targeting the CD14-dependent lipid peroxidation axis can attenuate secondary inflammatory neurodegeneration, is partially supported by the literature but requires further functional validation to confirm direct causality.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nTranscriptomic and multi-model analysis in spinal cord injury (SCI) indicates that pyroptosis, necroptosis, and ferroptosis are persistently activated, and CD14 is identified as a hub gene linked to these signatures and myeloid inflammatory activation. While current evidence supports a strong association between CD14 expression, lytic cell death, and myeloid inflammatory responses, the direct causal role of CD14 in modulating these specific lipid peroxidation-dependent cell death pathways requires functional experimental confirmation.\n\n### [INTRODUCTION & JUSTIFICATION]\nSecondary injury following SCI involves complex, interconnected mechanisms including oxidative stress, inflammation, and programmed cell death. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI. Evidence from related models underscores that rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   CD14 is identified as the most robust candidate hub gene connecting lytic cell death signatures (pyroptosis, necroptosis, ferroptosis) to myeloid inflammatory activation post-SCI.\n*   Ferroptosis in microglia acts as an upstream driver of sustained neuroinflammation, linking iron dyshomeostasis and lipid peroxidation to inflammatory amplification.\n*   Ninjurin1 (NINJ1) functions as a terminal executor of plasma membrane rupture across multiple cell death modes, including ferroptosis and pyroptosis, positioning it as a structural nexus in lytic cell death.\n*   Recent data suggest that PANoptosis\u2014the synergistic activation of pyroptosis, apoptosis, and necroptosis via the PANoptosome\u2014is a major contributor to SCI secondary injury.\n*   Therapeutic modulation via adipose-derived ECM hydrogels loaded with cytokines or antioxidants (e.g., QM complexes) shows promise in suppressing ferroptosis and mitigating SCI-induced neuronal loss.\n*   Specific mechanosensitive channels like Piezo1 in microglia mediate mitochondrial dysfunction and ferroptosis, with their inhibition proving protective against secondary inflammatory damage.\n*   Sphingosine-1-phosphate receptor 2 (S1P2) signaling represents a distinct pathway driving neuronal ferroptosis following contusive SCI.\n*   GADD45A has been identified as a critical regulator that coordinates both ferroptosis and apoptosis via the NF-\u03baB pathway in SCI models.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

in acute SCI, its surge likely triggers systemic inflammatory signaling pathways (such as TLR4/NF-\u03baB), whereas in chronic stages, it may function as a feedback node perpetuating lytic death cycles through continued lipid peroxidation susceptibility.\",\n  \"co-activation_kinetics\": \"Data indicate that pyroptosis and ferroptosis begin in the acute phase and persist. CD14 currently appears as a robust co-expressed hub gene rather than a proven upstream trigger; it is most likely a participant in the inflammatory feedback loop that serves to maintain the activation state of these death programs.\"\n}\n###JSON_END###",

However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse."

Necroptosis, a caspase-independent inflammatory form of programmed cell death, has emerged as a critical driver of the pathogenesis of cardiovascular disorders, neurodegenerative diseases, and cancer. Concurrently, our understanding of mitochondrial biology has undergone a paradigm shift: mitochondria are no longer viewed merely as bioenergetic powerhouses, but as dynamic signalling hubs that orchestrate metabolic reprogramming, cellular homeostasis, and ultimate cell fate decisions. In this regard, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This review delineates the mechanistic interplay between necroptosis and mitochondrial dysfunction and systematically analyzes the key molecular mediators and pathological pathways through which mitochondrial dysregulation drives necroptotic activation. Furthermore, this review identifies actionable therapeutic targets and translational strategies for modulating necroptosis in related diseases."

The core pathological event of CaOx crystals is the damage of renal tubular epithelial cells (RTECs). Recent studies have shown that CaOx crystals can induce a variety of programmed cell death (PCD) pathways, such as apoptosis, pyroptosis, necroptosis, and ferroptosis, in RTECs at the same time, and there are complex compensations and crosstalk between these death pathways, resulting in the limited efficacy of a single targeting strategy. Therefore, exploring the mechanisms that can integrate the regulation of multiple cell death pathways has become an important direction in this field. PANoptosis is an inflammatory PCD mode driven by the PANoptosome complex, which synchronously triggers the characteristic events of three death pathways in the same cell through the cooperative integration of the core molecular components of pyroptosis, apoptosis, and necroptosis. In this process, cysteinyl aspartate-specific proteinase-8 (Caspase-8) and receptor-interacting serine/threonine kinase 3 (RIPK3), as the core components of the PANoptosome, jointly determine whether the cell goes to a single programmed death or an integrated PANoptosis. The limited studies' evidence supports that CaOx crystals induce concurrent activation of apoptosis, pyroptosis, and necroptosis, suggesting the possibility of PANoptosis in CaOx\u2011induced kidney injury. At the same time, the rupture of the cell membrane caused by PANoptosis, similar to other forms of PCD, releases a large number of damage-associated molecular patterns (DAMPs), which activate innate immunity to form an inflammatory cascade and further aggravates tissue damage. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. In the future, new biomarkers and multi-target intervention strategies should be developed based on PANoptosis, which is expected to open up a new path for the prevention and treatment of CaOx-induced kidney injury."

It reflects the coordinated involvement of apoptosis, pyroptosis, and necroptosis, usually through the PANoptosome in a shared pathological environment. This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. Neural tissue is particularly sensitive to oxidative stress, mitochondrial dysfunction, immune-mediated inflammation, and blood-brain barrier disruption. These pathological changes are common in many forms of neural injury. Therefore, abnormal PANoptosis activation may provide a common mechanism linking different types of nervous system damage. This review summarizes the historical evolution, molecular mechanisms, disease-related roles, and intervention strategies of PANoptosis in neurological disorders. It focuses on PANoptosome assembly and key mechanistic nodes, including NOD-like receptor family pyrin domain-containing 3 (NLRP3), caspase-8, the receptor-interacting serine/threonine protein kinase 1 (RIPK1)/receptor-interacting serine/threonine protein kinase 3 (RIPK3)/mixed lineage kinase domain-like protein (MLKL) axis, gasdermin D (GSDMD), and Ninjurin 1 (NINJ1).

While metabolic reprogramming is linked to immune evasion, the precise mechanistic orchestration remains unclear. Here, utilizing single-cell transcriptomics and quantitative lactylome profiling, we show that elevated tumor lactate drives resistance by broadly suppressing PANoptosis. Mechanistically, under chemotherapeutic stress, the Lysine acetyltransferase 8 (KAT8) catalyzes the specific lactylation of the inner mitochondrial membrane ADP/ATP translocator 2 (ANT2)\u00a0at K92. Lactylated ANT2 recruits the phosphoglycerate mutase 5\u00a0(PGAM5) to dephosphorylate Cyclophilin D (CypD). This cascade restricts mitochondrial permeability transition pore (mPTP) opening, preserving mitochondrial homeostasis and averting immunogenic cell death. Crucially, a cell-penetrating competitive peptide targeting the KAT8-ANT2 interface effectively uncouples this metabolic lock, re-sensitizing TNBC tumors to cytotoxic stress and restoring chemo-immunotherapy efficacy in vivo. Our findings unveil a profound mechanistic link between the Warburg effect and mitochondrial homeostasis, establishing KAT8-mediated ANT2 lactylation as a targetable vulnerability to improve chemo-immunotherapy efficacy."

Allicin (3.6\u202fmg/kg) was injected via the tail vein 5\u202fmin before reperfusion. Myocardial damage (cardiac function, structure, cTnT, CK-MB and apoptosis), PANoptosome components (RIPK1/3, caspase-8, ASC and NLRP3), PANoptosis indicators (MLKL, GSDMD, IL-1\u03b2/18 and caspase-3) were assessed to evaluate the cardioprotective effects of allicin. Subsequently, the potential signaling pathway related to PANoptosis and therapeutic targets of allicin were screened through transcriptomic analysis, and TLR4 signaling was selected for verification. Then, H9C2 cells were used to establish an oxygen-glucose deprivation/reperfusion (OGD/R) model. The TLR4 inhibitor TAK-242, agonist RS09, and allicin were used to clarify the pathological role of TLR4 in myocardial PANoptosis and the therapeutic target of allicin by measuring the indicators of myocardial damage, PANoptosis and TLR4 expression. In vivo experiments revealed that allicin alleviated MI/R injury and reduced both myocardial PANoptosome components and PANoptosis. Based on transcriptomic analysis and published studies, the TLR4 signaling pathway was selected to verify the pathological role in PANoptosis and the therapeutic effects of allicin. In vitro experiments demonstrated that TLR4 activation further aggravated OGD/R-induced PANoptosis and increased TLR4 expression. Conversely, both allicin and the TLR4 inhibitor suppressed myocardial PANoptosis and TLR4 expression. Allicin can reduce myocardial PANoptosis and ameliorate MI/R injury by inhibiting TLR4 activation. These findings provide a new target and strategy for the treatment of MI/R injury."

Increasing evidence indicates that regulated cell death (RCD) can act as an upstream amplifier in selected autoimmune settings, while in other settings it may mainly report downstream collateral injury caused by cytotoxic lymphocytes, immune complexes, complement activation, or tissue hypoxia. Accordingly, this review distinguishes causal death execution from associative pathway signatures and highlights the types of longitudinal, cell-type-resolved, and perturbational evidence needed to make that distinction. We summarize how apoptosis, necroptosis, pyroptosis, and ferroptosis operate as an interlocking network in autoimmune microenvironments, frequently co-existing as context-dependent mixed-death states driven by shared triggers such as cytokines, PRR ligands, and oxidative stress, and governed by decision hubs including RIPK1 and caspase-8. We highlight integrated concepts such as PANoptosis to explain pathway convergence and compensatory switching into parallel lytic branches when a single node is constrained. The review further connects mechanistic insights to translational priorities, emphasizing biomarker strategies that report pathway engagement, targeted modulation of executors or upstream sensing and cytokine circuits, and lesion-localized delivery approaches to improve the therapeutic window. Finally, we outline key gaps that must be addressed to enable precision interventions, including spatial and cell-type resolved validation of death programs, longitudinal profiling across flare-remission trajectories, and harmonized composite panels capable of capturing mixed-death dynamics in heterogeneous AIDs."

While these responses can be beneficial in host defense, aberrant activation of inflammatory, lytic cell death pathways can be pathogenic. Emerging evidence suggests that cellular metabolic disruption can promote inflammatory cell death, but the mechanistic connections between these processes are not well understood, limiting our ability to identify regulatory nodes that can be therapeutically targeted. Here, we found that intracellular levels of the metabolic cofactor nicotinamide adenine dinucleotide (NAD+) were depleted in response to cell death triggers that drive pyroptosis, necroptosis, PANoptosis, and ferroptosis. However, restoring NAD+ inhibited PANoptosis but not the other forms of cell death. Mechanistically, NAD+ restoration reduced the expression of PANoptotic sensors or regulators, including the transcription factor IRF1, a critical factor for innate immune sensor priming in PANoptosis. Our findings thereby suggest that NAD+ depletion is an early cell death signaling event and that restoring NAD+ levels specifically blocks PANoptosis by suppressing priming. Hence, targeting NAD+ metabolism represents a potential therapeutic strategy for infectious and inflammatory diseases associated with dysregulated PANoptosis."

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma."

While pharmacological, psychological, and physiotherapeutic approaches have been applied, including whole-body vibration (WBV), synaptic-level mechanisms of WBV remain largely unexplored. Here, we assessed the post-SCI pain-associated behavior index (PAB, based on established behavioral criteria) and compared synapse counts (SYN+, VGLUT1+, ChAT+, VGAT+), CGRP+- and SER+-structures, as well as astrocytic and microglial populations in the lumbar dorsal horn following thoracic SCI in WBV-treated and untreated rats. Animals received WBV from postoperative week 3 to 12, and outcomes were compared with non-treated controls. PAB was consistently reduced in WBV-treated animals. STED-microscopy quantification showed that WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals, as well as the number of SER\u2009+\u2009fibers.

Our data indicate that the WBV-induced frequent (15-30\u2005Hz) muscle contractions and proprioceptive impulses contribute to spasticity modulation (via VGAT-related mechanisms) and attenuation of post-SCI hyperalgesia (CGRP-associated). Together with the reduced astro- and microglia amounts, the described synaptic alterations are considered essential prerequisites for better motor recovery. These findings provide preclinical evidence for the functional benefits of WBV in an animal SCI model and warrant further investigations to determine mechanisms underpinning this non-invasive, low-cost and easily applicable rehabilitation approach."

We previously showed that intensified interaction between mutant ATXN1 and Capicua (CIC) drives SCA1 pathogenesis in the cerebellum, whereas ATXN1 loss augments amyloid \u03b2 production in the hippocampus and cortex. CIC, however, forms a complex with ATXN1 and its paralog, Ataxin-1-like (ATXN1L), yet knockout of either yields completely different phenotypes. To determine whether this could be due to CIC having two isoforms, we generated mice bearing either the long (CIC-L) or short (CIC-S) isoform. Loss of CIC-L led to cognitive deficits, whereas loss of CIC-S caused early postnatal lethality, phenocopying ATXN1 and ATXN1L knockout mice, respectively. Furthermore, CIC-L preferentially interacts with ATXN1, and CIC-S with ATXN1L.

The degenerative disc's harsh microenvironment promotes nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) death and hinders self repair. Mesencephalic astrocyte-derived neurotrophic factor (MANF), an atypical neurotrophic factor, has protective effects in degenerative diseases. However, its role in IDD is unclear. Assessment of MANF expression was conducted in both human nucleus pulposus tissues and a rat IVD puncture model. An in vitro model of degeneration was established by acid treatment of NP-MSCs, and the functional role of MANF was explored through its knockdown and overexpression. RNA sequencing was employed to identify downstream targets. The therapeutic potential of MANF-overexpressing NP-MSCs was evaluated in a rat puncture model. MANF expression was markedly downregulated in degenerated IVD tissues from both human patients and rat models. Correspondingly, in vitro experiments demonstrated that MANF knockdown exacerbated, while its overexpression mitigated, acid-induced apoptosis of NP-MSCs. Mechanistically, MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity, as demonstrated by the complete abolition of this protection upon treatment with the MAM uncoupler FATE1. Transcriptomic analysis and subsequent validation identified receptor expression-enhancing protein 1 (REEP1) as a critical downstream effector through which MANF safeguards MAM integrity. We further elucidated that MANF upregulates REEP1 expression by directly inhibiting miR-33b-5p. In vivo, transplantation of MANF-overexpressing NP-MSCs effectively attenuated IDD in a rat model. MANF protected NP-MSCs from acidosis by sustaining MAM integrity via the MiR-33b-5p/REEP1 axis. These findings reveal MANF's mechanism and therapeutic potential for IDD."

Botulinum neurotoxin type A (BoNT/A) has shown anti-inflammatory and neuroprotective effects in acute SCI, but its potential in the chronic phase remains unclear. This study investigates whether combining BoNT/A with electrical muscle stimulation (EMS) enhances recovery in chronic SCI. Adult mice with severe thoracic SCI (paraplegic) underwent EMS (30\u00a0min/d for 10 non-consecutive days starting 3 d post-injury) or no stimulation. Fifteen days after SCI, animals received a single intrathecal injection of BoNT/A (15\u00a0pg/5\u00a0\u03bcl) or saline. Functional recovery was assessed up to 60 d as well as in moderate and mild SCI mice. NeP onset and maintenance were evaluated. Spinal cord tissue was analysed for astrocytic and microglial morphology, neuronal and oligodendroglial survival, myelin protein expression, and in vitro effects on oligodendrocyte precursor cells (OPCs). The phenotype of hindlimb muscles was evaluated through morphological and gene expression analyses. EMS was able to counteract muscle atrophy and fibrosis, and when combined with BoNT/A, also denervation. Moreover, the combination restored hindlimb motor function in chronic SCI, whereas BoNT/A or EMS alone were ineffective. NeP, a common comorbidity associated with SCI, was mitigated by BoNT/A treatment even when administered in the chronic phase. BoNT/A reduced astrocytic hypertrophy and excitatory synapse association and was associated with a morphology-based redistribution of microglial profiles toward a resting-like classification, decreased apoptosis, and increased neuronal and oligodendroglial survival. Myelin basic protein (MBP) expression was significantly elevated in vivo. In vitro, BoNT/A promoted OPC differentiation into myelinating oligodendrocytes, increased process complexity, and upregulated MBP, galactocerebroside C, proteolipid protein, and myelin oligodendrocyte glycoprotein under both proliferative and differentiating conditions. Cleaved synaptosomal-associated protein 25 colocalization with OPC confirmed direct BoNT/A internalization and activity. BoNT/A exerts neuroprotective effects in chronic SCI by reducing neuroinflammation and supporting neuronal and oligodendroglial preservation. When combined with EMS, it also promotes remyelination and improves muscle homeostasis, suggesting that early stimulation creates a permissive environment for recovery. These findings support the clinical evaluation of BoNT/A as a therapeutic strategy for chronic SCI."

LD function is tightly intertwined with liquid-liquid phase separation (LLPS) and epigenetic remodeling, bridging cellular metabolism to gene expression and cell fate control. LD biogenesis relies on ER lipid structures, phase-separated protein assemblies and lipid regulatory proteins. Via contacts with multiple organelles, LDs regulate lipid catabolism, ferroptosis, inflammation and chromatin accessibility, while their metabolites directly reshape epigenetic modifications and transcription. LLPS-driven biomolecular condensates further coordinate LD-linked metabolic and stress signaling. Dysregulated LD remodeling mediates metabolic flexibility, immune escape and drug resistance in obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), neurodegeneration, viral infection and cancer.

Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition.

Recent literature suggests that CD14 serves as a robust candidate hub gene associated with myeloid inflammatory activation and lytic cell death signatures. While direct clinical evidence for CD14 inhibition as a singular PANoptosome-blocking strategy remains in the exploratory phase, the integration of CD14 into the broader framework of lytic cell death regulation provides a compelling mechanistic target to mitigate the progressive neuroinflammatory feed-forward loop.\n\n### [INTRODUCTION & JUSTIFICATION]\nSecondary injury after spinal cord injury (SCI) is a multifaceted pathological process characterized by persistent inflammation, oxidative stress, and multiple forms of programmed cell death (PCD). The literature identifies that lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. Crucially, the discovery that CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures highlights its potential role as a gatekeeper of the inflammatory response. \n\nThe mechanism by which this cell death occurs involves a complex coordination between metabolic and inflammatory pathways. For instance, PLIN2 interacts with the mitochondrial outer membrane protein PGAM5 to regulate lipid droplet-mitochondria contacts. This relationship is critical, as Genetic deletion of Plin2 markedly reduced lipid droplet burden, attenuated neuroinflammation, and promoted neuronal survival and functional recovery in vivo. These metabolic perturbations are not isolated; rather, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This dysfunction facilitates the \"ferroptotic storm,\" described as Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. \n\nFurthermore, the integration of multiple cell death pathways into a unified, inflammatory lytic model\u2014PANoptosis\u2014offers a critical framework for therapeutic intervention. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. The rationale for targeting these pathways in the central nervous system is that This concept may be especially useful in neurological diseases.

Benth. Ethanol Extract Attenuates LPS-Induced Neuroinflammation and Behavioral Deficits by Modulating TLR4/NF-\u03baB/NLRP3 Signaling Pathway.\nAbstract: Glycine tabacina (Labill.) Benth is commonly known as \"Yan-Dou\" and is a folk medicinal herb in China used to alleviate rheumatism. Although its anti-inflammatory and antioxidant activities have been reported, its effects on microglia-driven neuroinflammation, neuronal protection, and neuroinflammation-associated behavioral impairment have not been investigated. An LPS-stimulated microglial activation model was established using BV2 cells to evaluate the anti-neuroinflammation activity of Glycine tabacina extract (GTE) and to explore its underlying mechanisms. Neuroprotective efficacy was assessed using a BV2-HT22 conditioned interaction model to determine whether GTE mitigates microglia-mediated neuronal injury. A zebrafish model was used to examine the effects of GTE on LPS-induced neuroinflammatory phenotypes and behavioral deficits. GTE significantly inhibited LPS-induced neuroinflammation in BV2 microglia. GTE also showed a strong neuroprotective effect by suppressing HT22 cell death in the BV2-HT22 conditioned interaction model. Mechanistic assays indicated that the neuroprotective effects of GTE were associated with the inhibition of TLR4/NF-\u03baB/NLRP3 signaling cascade. In vivo studies showed that GTE mitigated LPS-stimulated neuroinflammatory phenotypes in both peripheral and central compartments and significantly improved behavioral performance in zebrafish. The results of this study demonstrate remarkable neuroprotective and anti-neuroinflammatory effects of GTE through regulation of the TLR4/NF-\u03baB/NLRP3 signaling pathway and highlight its potential as a therapeutic candidate for neuroinflammation-related CNS disorders.\n\nID: 42451075\nTitle: Maltol Protects Neuronal Cells by Alleviating Chronic Neuroinflammation, Pyroptosis, and Ferroptosis via HSP70 Upregulation in Microglia.\nAbstract: Objectives: Neuroinflammation is recognized as a significant characteristic of Alzheimer's disease (AD). Currently, there is a notable absence of effective pharmacological agents to prevent or treat neuroinflammatory processes associated with AD. Heat shock protein 70 (HSP70) is pivotal in the progression of neuroinflammation. In this study, we explored the potential of maltol, a Maillard reaction product derived from red ginseng, as a therapeutic agent for neuroinflammation. Methods: In vitro, HMC3 microglial cell models were developed to examine the regulatory effects of gradient concentrations of maltol (12.5, 25, 50 \u03bcM) on the TLR4/MyD88/NF-\u03baB p65 signaling pathway, neuroinflammation, and pyroptosis. Analyses of the GEO database and Gene Set Enrichment Analysis (GSEA) were performed to identify the core targets of maltol, followed by HSP70 gene silencing experiments to validate the targeted regulatory mechanism. Results: Maltol significantly mitigated LPS-induced neuronal damage and cognitive deficits in mice. It effectively suppressed microglia-mediated neuroinflammation and pyroptosis, reversed oxidative stress-induced neuronal ferroptosis, and inhibited neuronal apoptosis. In vitro experiments demonstrated that maltol obstructed TLR4/MyD88 binding, thereby inhibiting NF-\u03baB p65-mediated neuroinflammation and pyroptosis, while also alleviating excessive ROS accumulation to enhance oxidative stress and ferroptosis. Bioinformatics analysis identified HSP70 as a crucial target for the anti-inflammatory and antioxidant effects of maltol. Subsequent gene silencing experiments confirmed that maltol exerted its inhibitory effects on LPS-induced neuroinflammation and pyroptosis in an HSP70-dependent manner. Conclusions: Maltol exhibits significant protective effects against Alzheimer's disease-related neuroinflammation, oxidative stress, pyroptosis, and ferroptosis through the targeting of HSP70. This study elucidates the molecular mechanisms by which maltol improves neuroinflammatory injury and provides a novel theoretical foundation and therapeutic strategy for the intervention of Alzheimer's disease neuroinflammation using traditional Chinese medicine.\n\nID: 42259394\nTitle: Natural monomer compounds in neurodegenerative diseases: Targeting ferroptosis and neuroinflammation.\nAbstract: Neurodegenerative diseases (NDDs), including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, are characterized by progressive neuronal loss driven by oxidative stress, mitochondrial dysfunction, and chronic neuroinflammation. Ferroptosis, an iron-dependent and lipid peroxidation-associated form of regulated cell death, has recently been identified as a key contributor to neuronal vulnerability. Emerging evidence demonstrates that purified natural monomer compounds derived from medicinal plants exert potent neuroprotective effects by targeting ferroptosis and neuroinflammatory pathways. Representative agents such as curcumin, baicalin, resveratrol, and ginsenoside Rg1 activate nuclear factor E2-related factor-2 and glutathione peroxidase 4 signaling to preserve redox balance, while suppressing microglia-mediated inflammation through inhibition of toll-like receptor 4 pathways. This review highlights the interplay between ferroptosis and neuroinflammation in NDDs, summarizes the regulatory effects of bioactive herbal monomer compounds, and discusses recent advances in multi-omics profiling, nano-delivery strategies, and translational research. By modulating the ferroptosis-neuroinflammation axis, these compounds may represent promising therapeutic candidates for NDDs.\n\nID: 42233256\nTitle: Eicosapentaenoic acid intake modulates programmed cell death protein 1 receptors to prevent chronic pain and comorbid depression in mice.\nAbstract: Fibromyalgia is a frequently treatment-refractory chronic musculoskeletal pain disorder that often results in clinical depression; however, the role of neuroinflammatory signaling in comorbid depression remains unclear, including the contributions of anti-inflammatory omega-3 fatty acids like eicosapentaenoic acid (EPA). This study examined the efficacy of EPA ingestion for reducing chronic pain and depression comorbidity (CPDC) in a mouse model established using intermittent cold stress. Our results showed that oral EPA could alleviate mechanical and thermal hyperalgesia in CPDC mice. The preventive effect of EPA on depressive symptoms in CPDC mice was further confirmed. Western blot and immunofluorescence staining revealed that EPA can inhibit the enhanced neuroinflammatory signaling concomitant with increased astrocyte and microglia activation and elevated levels of inflammatory signaling factors high-mobility group box 1 (HMGB1) and S100B in the CPDC mice. Alternatively, oral EPA can increase the attenuated expression of the pain-inhibiting programmed cell death protein 1 (PD-1) receptor. EPA intake can further alleviate inflammation-associated toll-like receptor 4 (TLR4) and downstream signaling molecules myeloid differentiation primary response 88 (MyD88), TNF receptor associated factor 6 (TRAF6), and activated (phosphorylated) nuclear factor kappa-light-chain-enhancer of activated B cells (pNF\u03baB) in CPDC mouse brain. A similar response also observed in transient receptor potential vanilloid 1 gene knockout mice. This demonstration that oral EPA can prevent CPDC by inhibiting neuroinflammatory pathways could facilitate improved treatment strategies for CPDC.\n\nID: 41890219\nTitle: The influence of TLR4 signaling on retinal ganglion cell survival and angiogenic response in a mouse model of oxygen-induced retinopathy.\nAbstract: Retinopathy of prematurity (ROP) is a critical concern in neonatal care and potentially leads to vision impairment. Despite advancements in anti-VEGF treatments, the mechanisms driving pathological vitreoretinal neovascularization remain unclear. I examined the role of Toll-like receptor 4 (TLR4) in modulating inflammatory cytokines, angiogenesis, and neuronal cell protection in a mouse model of oxygen-induced retinopathy (OIR). C57BL/6J TLR4-/- mice were subjected to OIR by exposure to 75% oxygen from postnatal days 7 to 12 (P7 to P12) following approved protocols. I used immunohistochemistry to assess TLR4 expression at P19, real-time quantitative PCR for proinflammatory cytokines at P19, ex vivo fluorescent vascular imaging to evaluate retinal vascular changes at P19, and retinal neuronal cells death evaluated by whole-mounted retina stained with cresyl violet at P47. Statistical significance was determined using one-way ANOVA (p\u202f<\u202f0.05). Immunofluorescence demonstrated TLR4 expression in microglia in OIR retinas of wild-type mice but not in controls. Real-time PCR revealed significant upregulation of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP1) in OIR retinas, which was mitigated in TLR4-/- mice. Retinal angiogenesis significantly increased in wild-type OIR mice, whereas TLR4 knockdown inhibited these changes. Additionally, OIR caused approximately 30% neuronal cell death in the retinal ganglion cell layer, which was largely prevented in the TLR4-/- mice. These findings underscore TLR4's pivotal role in the regulation of inflammatory responses and angiogenesis in ROP. Targeting TLR4 may represent a novel therapeutic approach to preserve retinal integrity and improve visual outcomes in at-risk populations, particularly in premature infants.\n\nID: 41723296\nTitle: Sinensetin attenuates post-stroke depression via dual modulation of TLR4/NF-\u03baB-NRF2/GPX4 pathways.\nAbstract: Post-stroke depression (PSD) is a complex neuropsychiatric complication driven by neuroinflammation and ferroptosis, yet effective therapies remain limited. Sinensetin (SIN), a polymethoxylated flavone derived from citrus fruits, possesses potent anti-inflammatory and antioxidant properties. However, its therapeutic efficacy and underlying mechanisms in PSD have not been explored. To investigate this, a mouse model of PSD was established by combining photothrombotic stroke with low-dose lipopolysaccharide (LPS) administration. Mice were treated with SIN (25 and 50\u00a0mg/kg) for 14 days. Depressive-like behaviors were assessed using the sucrose preference test (SPT), tail suspension test (TST), and forced swimming test (FST). Crucially, protein-level validation was performed using quantitative immunofluorescence (for glial activation) and ELISA (for serum cytokines and pathway markers), complemented by qPCR and molecular docking/dynamics (MD) simulations. SIN treatment significantly alleviated depressive-like behaviors and restored cerebral blood flow in PSD mice. Quantitative immunofluorescence and ELISA analyses revealed that SIN effectively suppressed the hyperactivation of microglia (IBA1) and astrocytes (GFAP) in the hippocampus and reduced serum concentrations of pro-inflammatory cytokines (TNF-\u03b1, IL-6, IL-1\u03b2). Mechanistically, SIN inhibited the TLR4/NF-\u03baB signaling pathway by suppressing NF-\u03baB nuclear translocation and concurrently activated the NRF2/GPX4 antioxidant axis, thereby mitigating lipid peroxidation and neuronal ferroptosis. Additionally, molecular docking and MD simulations predicted energetically favorable interactions between SIN and key targets (e.g., TLR4, KEAP1), providing supportive evidence for its multi-target mechanism. Our findings demonstrate that SIN exerts neuroprotective effects in PSD by dually modulating TLR4/NF-\u03baB-mediated neuroinflammation and NRF2/GPX4-dependent ferroptosis. These results highlight SIN as a promising natural therapeutic candidate for the treatment of depression following stroke.\n\nID: 41702081\nTitle: Neuronal TLR4 upregulation activates the cGAS-STING pathway to induce ferroptosis in EAE mice.\nAbstract: Progressive neurofunctional impairment in multiple sclerosis (MS) is largely driven by neuronal damage and loss, yet the underlying molecular mechanisms remain poorly understood. This study aimed to investigate the role of neuronal Toll-like receptor 4 (TLR4) in promoting ferroptosis, an iron-dependent cell death pathway, during experimental autoimmune encephalomyelitis (EAE). We leveraged a MOG35-55-induced EAE mouse model (n\u00a0=\u00a010 per group) alongside in vitro LPS-stimulated SH-SY5Y mono- and co-culture systems (n\u00a0=\u00a03 biological replicates) to interrogate the crosstalk between TLR4 signaling and ferroptosis. This link was comprehensively evaluated via biochemical assays, Western blotting, RT-qPCR, co-immunoprecipitation, immunofluorescence analyses, and transmission electron microscopy. Furthermore, we mechanistically dissected the underlying signaling cascades using siRNA-mediated gene silencing and co-immunoprecipitation. Both in vivo and in vitro models recapitulated classical ferroptosis features, including NCOA4-mediated ferritinophagy, lipid peroxidation, and iron overload. Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism. Observations indicate that the TLR4 signaling contributes to ferroptosis even within the complex inflammatory microenvironment of microglia-neuron co-cultures. In EAE mice, pharmacological blockade of ferroptosis via Liproxstatin-1 appeared to ameliorate clinical severity, associated with restored neuronal GPX4 expression in the brain and spinal cord, and concomitantly suppressed lipid peroxidation. This study proposes a specific TLR4-mtDNA-cGAS-STING-NCOA4 signaling cascade that may facilitate neuronal ferroptosis in EAE mice. These findings suggest a novel mechanism of neuronal injury in MS and underscore that targeting this intrinsic neuronal pathway could represent a promising therapeutic strategy to ameliorate progressive neurodegeneration.\n\nID: 41008336\nTitle: Electroacupuncture Attenuates Fibromyalgia Pain Through Increased PD-1 Expression in Female Mice.\nAbstract: Fibromyalgia causes chronic long-term pain, with symptoms lasting for months to years. Given the lack of evidence-based methods for diagnosing and assessing fibromyalgia, it ranks among the most difficult chronic pain conditions to treat. Programmed cell death ligand 1 (PD-L1) can inhibit acute and chronic pain transmission by inhibiting neuronal ion channels. Here, we aimed to explore the analgesic efficacy and mechanism of PD-L1/PD1 in an intermittent cold stress-induced fibromyalgia pain mouse model. Von Frey and Hargreaves tests were performed, showing that the mouse model exhibited mechanical (day 4: 2.08 \u00b1 0.13 g, n = 9) and thermal hyperalgesia (day 4: 3.93 \u00b1 0.45 s, n = 9). Electroacupuncture (EA) or intraventricular PD-L1 injection effectively alleviated the nociceptive response and led to low PD-1 levels in the mouse dorsal root ganglia, spinal cord, thalamus, somatosensory cortex, and cerebellum, as measured through Western blots. In contrast, the pain-related kinase levels increased after fibromyalgia induction; these effects were reversed by EA and PD-L1 via the inhibition of microglia/astrocytes and Toll-like receptor 4. Our results show that EA can treat fibromyalgia pain in mice through effects on the PD-L1/PD1 pathway, indicating its potential as a therapeutic target in fibromyalgia.\n\nID: 40884073\nTitle: RIPK3 regulates microglial polarization through the TLR4/MyD88 pathway in neuropathic pain.\nAbstract: Peripheral nerve injury activates microglia in the spinal, promoting microglial polarization and facilitating neuropathic pain progression. Necroptosis, a form of cell death, plays a crucial role in various neurological diseases and receptor-interacting protein kinases 3(RIPK3) a key molecular in the process. This study investigates to explore that RIPK3 regulates microglial polarization through the TLR4/MyD88 signaling pathway in neuropathic pain. By using a chronic constriction injury (CCI) model in mice, we found that peripheral nerve injury promoted M1 polarization and activated the TLR4/MyD88 pathway in spinal cord; in BV-2 microglia models, TNF-\u03b1/Z-VAD co-induction triggered M1 polarization through TLR4/MyD88 pathway, TLR4 antagonists suppressed these effects both in vivo and in vitro. Administration of GSK'872 (RIPK3 inhibitor) inhibited TLR4/MyD88 pathway, reduced microglial M1 polarization, promoted microglial M2 polarization and alleviated CCI-induced hyperalgesia. These findings suggest that necroptosis is a key cellular mechanism in peripheral injury-induced neuropathic pain and that RIPK3 regulates microglial polarization via the TLR4/MyD88 pathway, providing a new target for neuropathic pain treatment and clinical prevention.\n\nID: 40829879\nTitle: Elevated expression of galectin-3 in microglia exacerbated neuron apoptosis via promoting TNF-\u03b1 release through the TLR4/NF-\u03baB signaling pathway.\nAbstract: High blood levels of galectin-3 (Gal-3) predict poor outcomes after intracerebral hemorrhage (ICH). Our previous study also showed that Gal-3 could aggravate ICH-induced brain injury through increasing neuroinflammatory activation and nerve cell death. In this study, we focus on the role of Gal-3 in nerve cell death after ICH. An ICH mice model and an in vitro co-stimulation model were established to study Gal-3's effect on neuron cell death via toll-like receptor 4 (TLR4)/nuclear factor kappa-B (NF-\u03baB) pathway. Western blot and immunofluorescence (IF) staining were applied for neuron apoptosis evaluation. Enzyme-linked immunosorbent assay (ELISA) was used to measure the production of neuroinflammation factors. Gal-3 expression in microglia was increased and positively correlated with the severity of neurological impairment after ICH. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and NeuN (or MAP2) double staining assay results revealed that the increasing of neuron cell apoptosis after Gal-3 treatment both in in vivo and in vitro co-stimulation experiments could be reversed by treatment with Gal-3 inhibitor MCP, TLR4 inhibitor TAK-242, NF-\u03baB inhibitor PDTC, or TNF-\u03b1 inhibitor C87 effectively. ELISA results revealed the same trends of TNF-\u03b1 release changes from microglia after Gal-3 or inhibitor treatment both in vivo and in vitro. WB results confirmed the Gal-3's role on apoptosis by the expression level of proteins such as FADD, Apaf-1, Bax, Cytochrome C, Caspase-8, and cleaved-Caspase-3 in neuron cells. The upregulation of Gal-3 in microglia after ICH could aggravate neuron cell apoptosis through increasing TNF-\u03b1 release via TLR4/NF-\u03baB pathway.\n\nID: 40816450\nTitle: Understanding the influence of TLR-mediated immune system on necroptosis-induced neurodegeneration in Parkinson's disease.\nAbstract: Neurodegeneration is a hallmark of various neurological disorders, including Parkinson's disease (PD), Alzheimer's disease (AD), stroke, and neurotropic viral infections. Although the precise etiology remains unclear, multiple pathological mechanisms contribute to disease progression, including mitochondrial dysfunction, protein aggregation, calcium excitotoxicity, endoplasmic reticulum (ER) stress, oxidative stress, immune system activation, and neuroinflammation. Among these, the immune response plays a crucial role in disease pathogenesis, acting as a defense mechanism against damage-associated molecular patterns (DAMPs), pathogen-associated molecular patterns (PAMPs), and toxic molecular species. Chronic immune activation, particularly of microglia, is a defining feature of neuroinflammation, which involves both innate and adaptive immune responses. In the central nervous system (CNS), microglia-mediated neuroinflammation leads to the release of proinflammatory cytokines, exacerbating neuronal damage. Necroptosis, a regulated form of programmed cell death, has been implicated in neuroinflammatory disorders, including PD. Persistent microglial activation in response to aggregated proteins stimulates various microglial receptors, which includes Toll-like receptor 4 (TLR4), that play a pivotal role in necroptosis activation via the myeloid differentiating primary response gene 88 (MYD88)-independent pathway. This review explores how immune system-mediated receptor activation triggers cell death pathways, with a focus on TLR-induced necroptosis in PD. In addition, we also discuss various downstream molecular mechanisms linking TLR signaling to necroptosis and discuss the potential of TLRs as therapeutic targets, offering insights for developing neuroprotective strategies in neurodegenerative diseases (NDDS).\n\nID: 40749850\nTitle: Nanoparticles loaded with a CSF1R antagonist selectively depletes microglial cells and modulates inflammation in spinal cord injury.\nAbstract: Neuroinflammation is a principal event occurring after spinal cord injury (SCI). M1-like microglia are key players in the inflammatory response after injury. We hypothesize that the depletion of this microglia subtype would shift the M2/M1-like microglia balance toward a more pro-resolutive environment, favorable to SCI repair. The colony-stimulating factor 1 receptor (CSF1R) antagonist PLX5622 has been used to deplete microglia in the central nervous system. Although PLX5622 can freely cross the blood-brain barrier after systemic administration, it requires solubilization in DMSO, an organic solvent toxic for the central nervous system, while the low drug concentration that accumulates at the SCI hampers its effectiveness. Systemic administration of PLX5622 can induce side effects due to off-target accumulation. In this study, for the first time, we specifically depleted M1-like microglia by designing polymeric nanoparticles loaded with PLX5622 (PLX NPs) to locally treat spinal cord contusion. PLX NP was prepared using a microfluidic-assisted approach showing high encapsulation efficiency (approx. 84\u00a0%), nanosized dimensions (100\u00a0nm), and batch-to-batch reproducibility. PLX NP displayed selective activity in depleting M1-like microglial cells in both resting and lipopolysaccharide (LPS)-activated mixed microglial cell models while preserving non-targeted glial cells. Furthermore, locally administered PLX NP downregulated proinflammatory cytokines (e.g., TNF-\u03b1, IL-6, and IL-1\u03b2), increasing the M2/M1-like microglia ratio, thus reducing inflammation in a SCI contusion model. Our data support the hypothesis that local treatment with PLX NP, a formulation with a high translational value, reduces neuroinflammation and shifts the microglia population toward a pro-resolutive phenotype, with potential applications in SCI and central nervous system inflammatory diseases.\n\nID: 40551989\nTitle: PANoptosis: Cross-Talk Among Apoptosis, Necroptosis, and Pyroptosis in Neurological Disorders.\nAbstract: Cell death mechanisms play a critical role in organismal development and homeostasis, primarily categorized into energy-dependent programmed cell death (PCD) and energy-independent necrotic cell death. PCD, regulated through various forms such as apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagic cell death, is essential for maintaining tissue stability and eliminating abnormal cells. Dysregulation of PCD is associated with numerous diseases, including cancer and neurodegenerative disorders. Recent studies have revealed extensive crosstalk and coordination among classical cell death pathways, leading to the identification of a novel programmed cell death mode termed PANoptosis. PANoptosis involves the dynamic assembly of the PANoptosome complex, which simultaneously activates apoptosis, pyroptosis, and necroptosis pathways in response to pathogen infection or tissue damage. In neurological diseases, PANoptosis exhibits dual roles: it can eliminate pathogen-infected cells but may also exacerbate neuroinflammation and neuronal death, contributing to the progression of neurodegenerative disorders. This review critically evaluates the molecular mechanisms of PANoptosis, its dual roles in neurological diseases (eg, Alzheimer's disease, Parkinson's disease, stroke, and glioma), and potential therapeutic strategies targeting PANoptosis, including small-molecule inhibitors, genome editing, and delivery technologies. By addressing conflicting evidence and outstanding questions, this review aims to provide a comprehensive framework for future research and clinical applications. Future research should focus on elucidating the molecular regulatory networks of PANoptosis, developing specific inhibitors, and advancing clinical applications to provide novel insights into the precise treatment of neurological diseases.\n\nID: 39852551\nTitle: Deep-Sea-Derived Isobisvertinol Targets TLR4 to Exhibit Neuroprotective Activity via Anti-Inflammatory and Ferroptosis-Inhibitory Effects.\nAbstract: Neuroinflammation and neuronal cell death are leading causes of death in the elderly and underlie various neurodegenerative diseases. These diseases involve complex pathophysiological mechanisms, including inflammatory responses, oxidative stress, and ferroptosis. Compounds derived from deep-sea fungi exhibit low toxicity and potent neuroprotective effects, offering a promising source for drug development. In this study, we isolated 44 natural products from deep-sea-derived fungi and identified isobisvertinol (17) as a compound with anti-inflammatory and ferroptosis-inhibiting effects. Using LPS-induced microglial inflammation and RSL3-induced neuronal ferroptosis models, we found that 17 targets TLR4 to provide neuroprotection. Molecular docking studies revealed that 17 inhibits TLR4 activation by occupying the hydrophobic pocket at the TLR4-MD2 binding site. Additionally, 17 suppresses TLR4, reducing p38 MAPK phosphorylation, and inhibits ferroptosis by decreasing lipid peroxidation and modulating mitochondrial membrane potential. Metabolomic analysis showed that 17 rescues alterations in multiple metabolic pathways induced by RSL3 and increases levels of antioxidant metabolites, including glutamine, glutamate, and glutathione. In summary, our results indicate that isobisvertinol (17) targets TLR4 in neural cells to reduce inflammation and inhibit p38 MAPK phosphorylation, while regulating metabolic pathways, mainly GSH synthesis, to provide antioxidant effects and prevent ferroptosis in neurons.\n\nID: 39830563\nTitle: Role of Adenosine A1 Receptor in Sleep Deprivation-Induced Neuroinflammation: Insights on Rapid Eye Movement Sleep and Fear Extinction Memory Recall in Rats.\nAbstract: Sleep deprivation (SD), stemming from a myriad of aetiologies, is a prevalent health condition frequently overlooked. It typically impairs memory consolidation and synaptic plasticity, potentially through neuroinflammatory mechanisms and adenosinergic signalling. It is still unclear whether the adenosine A1 receptor (A1R) modulates SD-induced neurological deficits in the hippocampus. This study aims to evaluate the effects of SD on fear extinction memory recall and emotional behaviour in male Sprague Dawley rats; to investigate the role of A1R antagonism by the administration of 8-cyclopentyltheophylline (8-CPT), an A1R antagonist during 48-hour SD in mitigating neuroinflammation and synaptic plasticity deficits induced by SD; and to assess changes in hippocampal neurogenesis, neuronal cell death, and sleep architecture in response to A1R antagonism during SD. A total of 39 animals were used in the study, and they were divided into three experimental groups: 1) cage control (CC; n = 13); 2) SD for 48 hours (SD; n = 13); 3) SD for 48 hours+ 8-CPT (20 mg/kg/day in 20% DMSO divided into two doses, morning and evening, i.p.; n = 13). 'n' refers to the sample size/number of animals in each group. Rats were subjected to SD after cued fear extinction training for 48 hours followed by fear extinction memory recall test, anxious-depressive-like behaviours by open field test (OFT), sucrose preference test, and forced swim test (FST). Levels of adenosine in the hippocampus were quantified by high-performance liquid chromatography. Protein levels of interleukin-6 (IL-6) and IL-10 were quantified by enzyme-linked immunosorbent assay (ELISA). Expression levels of proteins and genes of interest were analysed using immunohistochemistry and real-time polymerase chain reaction (RT-PCR), respectively. Sleep architecture was assessed by recording electroencephalography (EEG), electromyography, and electrooculography from rats. Administration of CPT during SD reversed extinction recall impairments (p = 0.01), improved line crossings in OFT, sucrose preference (p < 0.01), and reduced immobility during the FST (p < 0.01). Immunohistochemical analysis of DG, CA3, and CA1 regions of the hippocampus revealed a significant upregulation of A1R expression in the SD and SD+CPT groups (p < 0.001, n = 5). Expression of post-synaptic density protein (PSD-95) and synaptophysin increased and a marked reduction in the Toll-like receptor-4\u00a0(TLR-4) expression in activated microglia in the SD+CPT group. 8-CPT partially restored SD-induced decline in serotonin and brain-derived neurotrophic factor. SD-induced neuronal apoptosis through caspase-3 and the P-p38 mitogen-activated protein kinase pathway was partially reversed by 8-CPT. RT-PCR results showed that A1R antagonism attenuated gene expression of pro-inflammatory cytokines (IL-1\u03b2, TNF\u03b1, p-NF\u03baB s536, and IL-6) and increased anti-inflammatory cytokines (IL-1ra, IL-4, IL-10, IL-11, and IL-13) during SD. EEG recordings revealed that A1R antagonism increased REM sleep without affecting non-REM sleep during SD, leaving rebound sleep unaffected.\u00a0 Conclusion: These findings highlight the role of A1R antagonism in restoring fear extinction memory recall, synaptic plasticity, adult neurogenesis, neuronal cell death, and attenuating neuroinflammation during SD, paving the way for the further exploration of its therapeutic potential in sleep-related cognitive deficits.\n\nID: 39342323\nTitle: AIBP controls TLR4 inflammarafts and mitochondrial dysfunction in a mouse model of Alzheimer's disease.\nAbstract: Microglia-driven neuroinflammation plays an important role in the development of Alzheimer's disease. Microglia activation is accompanied by the formation and chronic expression of TLR4 inflammarafts, defined as enlarged and cholesterol-rich lipid rafts serving as an assembly platform for TLR4 dimers and complexes of other inflammatory receptors. The secreted apoA-I binding protein (APOA1BP or AIBP) binds TLR4 and selectively targets cholesterol depletion machinery to TLR4 inflammaraft-expressing inflammatory, but not homeostatic microglia. Here we demonstrated that amyloid-beta (A\u03b2) induced formation of TLR4 inflammarafts in microglia in vitro and in the brain of APP/PS1 mice. Mitochondria in Apoa1bp-/- APP/PS1 microglia were hyperbranched and cupped, which was accompanied by increased reactive oxygen species and the dilated endoplasmic reticulum. The size and number of A\u03b2 plaques and neuronal cell death were significantly increased, and the animal survival was decreased in Apoa1bp-/-APP/PS1 compared to APP/PS1 female mice. These results suggest that AIBP exerts control of TLR4 inflammarafts and mitochondrial dynamics in microglia and plays a protective role in Alzheimer's disease associated oxidative stress and neurodegeneration.\n\nID: 39218334\nTitle: Formononetin inhibits neuroinflammation in BV2 microglia induced by glucose and oxygen deprivation reperfusion through TLR4/NF-\u03baB signaling pathway.\nAbstract: Ischemic stroke, caused by diminished or interrupted cerebral blood flow, triggers the activation of microglial cells and subsequent inflammatory responses. Formononetin (FMN) has been observed to inhibit BV2 microglial cell activation and alleviate ensuing neuroinflammatory reactions. Despite extensive research, the precise underlying mechanism remains unclear. To investigate the neuroinflammatory response following FMN-mediated inhibition of BV2 microglial activation, we employed an in vitro oxygen-glucose deprivation/reperfusion (OGD/R) model. BV2 microglial cells were categorized into four groups: control, FMN, OGD/R, and OGD/R+FMN. Cell viability was assessed using the CCK-8 assay, while flow cytometry assessed M1 and M2 cell populations within BV2 cells. Immunofluorescence was utilized to detect the expression levels of apoptosis-inducing factor (AIF), p53, Toll-like receptor 4 (TLR4), and NF-\u03baB p65. Western blotting (WB) was conducted to quantify p65/p-p65, I\u03baB-\u03b1/p-I\u03baB-\u03b1, and TLR4 protein levels in each group. Additionally, ELISA was employed to measure IL-1\u03b2 and TNF-\u03b1 levels in cell supernatants from each group. The results revealed a significant increase in the proportion of iNOS/CD206-positive M1/M2 cells in the OGD/R group compared to the control group (p\u00a0<\u00a00.05). There was also a notable increase in nuclear translocation of NF-\u03baB p65 and elevated expression of inflammatory factors IL-1\u03b2 and TNF-\u03b1 in cell supernatants. Moreover, levels of p-p65, p-I\u03baB-\u03b1, and TLR4 proteins were significantly elevated in the OGD/R group (p\u00a0<\u00a00.05). However, the addition of FMN reversed these effects. Specifically, FMN administration notably attenuated cell death and inflammation in BV2 microglia induced by OGD/R through modulation of the TLR4/NF-\u03baB signaling pathway.These findings suggest that FMN may serve as a potential therapeutic agent against neuroinflammation associated with ischemic stroke by targeting microglial activation pathways.\n\nID: 39147737\nTitle: Toll-like receptor 4 deficiency in Purkinje neurons drives cerebellar ataxia by impairing the BK channel-mediated after-hyperpolarization and cytosolic calcium homeostasis.\nAbstract: Toll-like receptor (TLR) 4 contributes to be the induction of neuroinflammation by recognizing pathology-associated ligands and activating microglia. In addition, numerous physiological signaling factors act as agonists or antagonists of TLR4 expressed by non-immune cells. Recently, TLR4 was found to be highly expressed in cerebellar Purkinje neurons (PNs) and involved in the maintenance of motor coordination through non-immune pathways, but the precise mechanisms remain unclear. Here we report that mice with PN specific TLR4 deletion (TLR4PKO mice) exhibited motor impairments consistent with cerebellar ataxia, reduced PN dendritic arborization and spine density, fewer parallel fiber (PF) - PN and climbing fiber (CF) - PN synapses, reduced BK channel expression, and impaired BK-mediated after-hyperpolarization, collectively leading to abnormal PN firing. Moreover, the impaired PN firing in TLR4PKO mice could be rescued with BK channel opener. The PNs of TLR4PKO mice also exhibited abnormal mitochondrial structure, disrupted mitochondrial endoplasmic reticulum tethering, and reduced cytosolic calcium, changes that may underly abnormal PN firing and ultimately drive ataxia. These results identify a previously unknown role for TLR4 in regulating PN firing and maintaining cerebellar function.\n\nID: 38834844\nTitle: DL-3-n-Butylphthalide Ameliorates Post-stroke Emotional Disorders by Suppressing Neuroinflammation and PANoptosis.\nAbstract: Post-stroke emotional disorders such as post-stroke anxiety and post-stroke depression are typical symptoms in patients with stroke. They are closely associated with poor prognosis and low quality of life. The State Food and Drug Administration of China has approved DL-3-n-butylphthalide (NBP) as a treatment for ischemic stroke (IS). Clinical research has shown that NBP alleviates anxiety and depressive symptoms in patients with IS. Therefore, this study explored the role and molecular mechanisms of NBP in cases of post-stroke emotional disorders using network pharmacology and experimental validation. The results showed that NBP treatment significantly increased the percentage of time spent in the center of the middle cerebral artery occlusion (MCAO) rats in the open field test and the percentage of sucrose consumption in the sucrose preference test. Network pharmacology results suggest that NBP may regulate neuroinflammation and cell death. Further experiments revealed that NBP inhibited the toll-like receptor 4/nuclear factor kappa B signaling pathway, decreased the level of pro-inflammatory cytokines, including tumor necrosis factor-\u03b1, interleukin-1\u03b2, and interleukin-6, and M1-type microglia markers (CD68, inducible nitric oxide synthase), and reduced the expression of PANoptosis-related molecules including caspase-1, caspase-3, caspase-8, gasdermin D, and mixed lineage kinase domain-like protein in the hippocampus of the MACO rats. These findings demonstrate that the mechanisms through which NBP ameliorates post-stroke emotional disorders in rats are associated with inhibiting neuroinflammation and PANoptosis, providing a new strategy and experimental basis for treating post-stroke emotional disorders.\n\nID: 38800857\nTitle: Nobiletin derivative, 5-acetoxy-6,7,8,3',4'-pentamethoxyflavone, inhibits neuroinflammation through the inhibition of TLR4/MyD88/MAPK signaling pathways and STAT3 in microglia.\nAbstract: Microglia in the central nervous system regulate neuroinflammation that leads to a wide range of neuropathological alterations. The present study investigated the anti-neuroinflammatory properties of nobiletin (Nob) derivative, 5-acetoxy-6,7,8,3',4'-pentamethoxyflavone (5-Ac-Nob), in lipopolysaccharide (LPS)-activated BV2 microglia. By using the MTT assay, Griess method, flow cytometry, and enzyme-linked immunosorbent assay (ELISA), we determined the cell viability, the levels of nitric oxide (NO), reactive oxygen species (ROS), and pro-inflammatory factors (interleukin 1 beta; IL-1\u03b2, interleukin 6; IL-6, tumor necrosis factor alpha; TNF-\u03b1 and prostaglandin E2; PGE2) in LPS-stimulated BV2 microglia. Toll-like receptor 4 (TLR4)-mediated myeloid differentiation primary response gene 88 (MyD88)/nuclear factor-kappa B (NF-\u03baB), mitogen-activated protein kinase (MAPK) signaling pathway and signal transducer and activator of transcription 3 (STAT3) were measured by western blotting. Analysis of NO generation and mRNA of pro-inflammatory cytokines was confirmed in the zebrafish model. 5-Ac-Nob reduced cell death, the levels of NO, ROS, inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), and pro-inflammatory factors in LPS-activated BV-2 microglial cells. TLR4-mediated MyD88/NF-\u03baB and MAPK pathway (p38, ERK and JNK) after exposure to 5-Ac-Nob was also suppressed. Moreover, 5-Ac-Nob inhibited phosphorylated STAT3 proteins expression in LPS-induced BV-2 microglial cells. Furthermore, we confirmed that 5-Ac-Nob decreased LPS-induced NO generation and mRNA of pro-inflammatory cytokines in the zebrafish model. Our findings suggest that 5-Ac-Nob represses neuroinflammatory responses by inhibiting TLR4-mediated signaling pathway and STAT3. As a result of these findings, 5-Ac-Nob has potential as an anti-inflammatory agent against microglia-mediated neuroinflammatory disorders.\n\nID: 38597275\nTitle: Emodin relieves morphine-stimulated BV2 microglial activation and inflammation through the TLR4/NF-\u03baB/NLRP3 pathway.\nAbstract: The objective of this study is to disclose the role of emodin, a natural anthraquinone derivative that has been proposed to suppress microglial activation and inflammation, in morphine tolerance. Here, cell counting kit-8 method assayed the viability of BV2 microglial cells treated by ascending concentrations of emodin. In emodin-pretreated BV2 microglial cells challenged with morphine with or without transfection of toll-like receptor 4 (TLR4) overexpression plasmids, transwell assay measured cell migration. Immunofluorescence staining and western blot detected the expression of microglial markers. Inflammatory levels were subjected to ELISA and western blot. BODIPY 581/591 C11 assay estimated lipid reactive oxygen species activity. Iron assay kit examined total iron content. Western blot tested the expression of ferroptosis- and TLR4/nuclear factor-kappaB (NF-\u03baB)/NOD-like receptor 3 (NLRP3) pathway-associated proteins. Molecular docking predicted the binding affinity of emodin to TLR4. Emodin was noted to obstruct the migration, activation, inflammatory response, and ferroptosis of BV2 microglial cells induced by morphine. In addition, emodin had a high binding affinity with TLR4 and inactivated TLR4/NF-\u03baB/NLRP3 pathway in morphine-challenged BV2 microglial cells. Upregulation of TLR4 partially countervailed the protective role of emodin against morphine-elicited BV2 microglial cell migration, activation, inflammation, and ferroptosis. Accordingly, emodin might target TLR4 and act as an inactivator of TLR4/NF-\u03baB/NLRP3 pathway, thus inhibiting BV2 microglial activation and inflammation to mitigate morphine tolerance.\n\nID: 38274789\nTitle: Mechanisms of immune response and cell death in ischemic stroke and their regulation by natural compounds.\nAbstract: Ischemic stroke (IS), which is the third foremost cause of disability and death worldwide, has inflammation and cell death as its main pathological features. IS can lead to neuronal cell death and release factors such as damage-related molecular patterns, stimulating the immune system to release inflammatory mediators, thereby resulting in inflammation and exacerbating brain damage. Currently, there are a limited number of treatment methods for IS, which is a fact necessitating the discovery of new treatment targets. For this review, current research on inflammation and cell death in ischemic stroke was summarized. The complex roles and pathways of the principal immune cells (microglia, astrocyte, neutrophils, T lymphocytes, and monocytes/macrophage) in the immune system after IS in inflammation are discussed. The mechanisms of immune cell interactions and the cytokines involved in these interactions are summarized. Moreover, the cell death mechanisms (pyroptosis, apoptosis, necroptosis, PANoptosis, and ferroptosis) and pathways after IS are explored. Finally, a summary is provided of the mechanism of action of natural pharmacological active ingredients in the treatment of IS. Despite significant recent progress in research on IS, there remain many challenges that need to be overcome.\n\nID: 37952561\nTitle: Spatiotemporal expression patterns of ZBP1 in the brain of mouse experimental stroke model.\nAbstract: Z-DNA binding protein 1 (ZBP1) is a cytosolic nucleic acid sensor, functioning as a critical mediator of inflammation and cell death pathways. Since neuroinflammation could occur in response to damage-associated molecular patterns (DAMPs), ZBP1 might be involved in neuroinflammation after stroke. However, the spatiotemporal expression profile of ZBP1 in the post-stroke brain remains to be elucidated. The aim of this study is to demonstrate the spatiotemporal expression patterns of ZBP1 in the post-stroke brain using a mouse photothrombotic stroke model. Real-time PCR assays showed that ZBP1 is induced on days 3-14 post stroke. ZBP1 immunoreactivity was observed in Iba1-positive microglia/macrophages in peri-infarct regions by immunohistochemistry. ZBP1-positive cells were spread in layers surrounding the infarct core by 7-14 days post stroke. Interestingly, ZBP1 immunoreactivity was also detected in CD206-positive border-associated macrophages (BAMs) in the meninges. Furthermore, ZBP1-expressing cells were positive for antibodies against inflammatory mediators such as Toll-like receptor 4 (TLR4), Toll/IL-1R domain-containing adaptor-inducing IFN-\u03b2 (TRIF), and receptor-interacting serine/threonine-protein kinase 1 (RIPK1). Morphological analysis with confocal microscopy showed that the co-localization signals of ZBP1 and its adaptor, TRIF, are increased by glucose oxidase (GOx) treatment, which has been reported to induce mitochondrial DNA (mtDNA) release. These results suggest that ZBP1 is induced in peri-infarct microglia/macrophages and may be involved in DAMPs-mediated neuroinflammation involving mtDNA in the post-infarct brain.\n\nID: 37915571\nTitle: Novel insight into cGAS-STING pathway in ischemic stroke: from pre- to post-disease.\nAbstract: Ischemic stroke, a primary cause of disability and the second leading cause of mortality, has emerged as an urgent public health issue. Growing evidence suggests that the Cyclic GMP-AMP synthase (cGAS)- Stimulator of interferon genes (STING) pathway, a component of innate immunity, is closely associated with microglia activation, neuroinflammation, and regulated cell death in ischemic stroke. However, the mechanisms underlying this pathway remain inadequately understood. This article comprehensively reviews the existing literature on the cGAS-STING pathway and its multifaceted relationship with ischemic stroke. Initially, it examines how various risk factors and pre-disease mechanisms such as metabolic dysfunction and senescence (e.g., hypertension, hyperglycemia, hyperlipidemia) affect the cGAS-STING pathway in relation to ischemic stroke. Subsequently, we explore in depth the potential pathophysiological relationship between this pathway and oxidative stress, endoplasmic reticulum stress, neuroinflammation as well as regulated cell death including ferroptosis and PANoptosis following cerebral ischemia injury. Finally, it suggests that intervention targeting the cGAS-STING pathway may serve as promising therapeutic strategies for addressing neuroinflammation associated with ischemic stroke. Taken together, this review concludes that targeting the microglia cGAS-STING pathway may shed light on the exploration of new therapeutic strategies against ischemic stroke.\n\nID: 37698533\nTitle: Galectin-3 promotes brain injury by modulating the phenotype of microglia via binding TLR-4 after intracerebral hemorrhage.\nAbstract: Intracerebral hemorrhage (ICH) is a stroke subtype with high mortality and disability rate, and neuroinflammation is involved in secondary brain injury. Galectin-3 (Gal-3) is one of the scaffold proteins of Galectins. Studies have indicated that Gal-3 plays an important role in the physiological and pathological state of the nervous system. Here we focus on the role of Gal-3 in ICH, especially in neuroinflammation. Injection of autologous blood into the right basal ganglia was used to simulate ICH injury, and the level of Gal-3 in brain was regulated by related means. The changes of Gal-3 were detected by western blot and immunofluorescence, the level of neuroinflammation by immunofluorescence staining and ELISA. Apoptosis and neuron loss were detected by TUNEL staining FJB staining and Nissl staining, and neurological deficits were judged by neurobehavioral tests. The protein level of Gal-3 increased at 24 h after ICH. Downregulation of Gal-3 level can reduce the infiltration of M1-type microglia and peripheral inflammatory cells, thus alleviating post-ICH neuroinflammation, and reducing cell apoptosis and neuron loss in brain tissue. ICH-induced neurological damage was rescued. Meanwhile, the promotion in the expression level of Gal-3 increased neuroinflammatory activation and nerve cell death, aggravating ICH-induced brain injury. This study proves that Gal-3 is involved in neuroinflammation and nerve damage after ICH. Gal-3 expression should not be encouraged early on to prevent neuroinflammation. which provides a new possibility for clinical treatment for ICH patients.\n\nID: 37277081\nTitle: Saikosaponin B2 ameliorates depression-induced microglia activation by inhibiting ferroptosis-mediated neuroinflammation and ER stress.\nAbstract: Saikosaponins B2 (SSB2) is one of the main active components isolated from Radix Bupleuri (Bupleurum chinense DC.), a herb widely used of traditional Chinese medicine. It has been used for the treatment of depression for more than two thousand years. However, the molecular mechanisms remain to be determined. In this study, we evaluated the anti-inflammatory effect and elucidated underlying molecular mechanisms of SSB2 in LPS-induced primary microglia and CUMS-induced mice model of depression. The effects of SSB2 treatment were investigated both in vitro and in vivo. The chronic unpredictable mild stimulation (CUMS) procedure was applied to establish the animal model of depression. Behavioural tests were used to evaluate the depressive-like behaviors in CUMS-exposed mice, including sucrose preference test, open field test, tail suspension test, and forced swimming test. The GPX4 gene of microglia was silenced using shRNA, and inflammatory cytokines were determined by Western Blot and immunofluorescence analysis. Endoplasmic reticulum stress and ferroptosis-related markers were detected by qPCR, flow cytometry and confocal microscopy. SSB2 reversed depressive-like behaviours in CUMS-exposed mice and relieved central neuroinflammation and ameliorated hippocampal neural damage. SSB2 alleviated LPS-induced activation of microglia through the TLR4/NF-\u03baB pathway. LPS-induced ferroptosis, with increased levels of ROS, intracellular Fe2+, mitochondrial membrane potential, lipid peroxidation, GSH, SLC7A11, FTH, GPX4 and Nrf2, and decreased transcription levels of ACSL4 and TFR1, was attenuated with SSB2 treatment in primary microglia cells. GPX4 knockdown activated ferroptosis, induced endoplasmic reticulum (ER) stress, and abrogated the protective effects of SSB2. Further, SSB2 attenuated ER stress, balanced calcium homeostasis, reduced lipid peroxidation and intracellular Fe2+ content by regulating the level of intracellular Ca2+. Our study suggested that SSB2 treatment can inhibit ferroptosis, maintain calcium homeostasis, relieve endoplasmic reticulum stress and attenuate central neuroinflammation. SSB2 exhibited anti-ferroptosis and anti-neuroinflammatory effects through the TLR4/NF-\u03baB pathway in a GPX4-dependent manner.\n\nID: 36803990\nTitle: Regulatory T cells alleviate myelin loss and cognitive dysfunction by regulating neuroinflammation and microglial pyroptosis via TLR4/MyD88/NF-\u03baB pathway in LPC-induced demyelination.\nAbstract: Demyelination occurs in multiple central nervous system (CNS) disorders and is tightly associated with neuroinflammation. Pyroptosis is a form of pro-inflammatory and lytic cell death which has been observed in CNS diseases recently. Regulatory T cells (Tregs) have exhibited immunoregulatory and protective effects in CNS diseases. However, the roles of Tregs in pyroptosis and their involvement in LPC-induced demyelination have not been explicated. In our study, Foxp3-diphtheria toxin receptor (DTR) mice treated with diphtheria toxin (DT) or PBS were subjected to two-site lysophosphatidylcholine (LPC) injection. Immunofluorescence, western blot, Luxol fast blue (LFB) staining, quantitative real-time PCR (qRT-PCR) and neurobehavior assessments were performed to evaluate the severity of demyelination, neuroinflammation and pyroptosis. Pyroptosis inhibitor was further used to investigate the role of pyroptosis in LPC-induced demyelination. RNA-sequencing was applied to explore the potential regulatory mechanism underlying the involvement of Tregs in LPC-induced demyelination and pyroptosis. Our results showed that depletion of Tregs aggravated microgliosis, inflammatory responses, immune cells infiltration and led to exacerbated myelin injury as well as cognitive defects in LPC-induced demyelination. Microglial pyroptosis was observed after LPC-induced demyelination, which was aggravated by Tregs depletion. Inhibition of pyroptosis by VX765 reversed myelin injury and cognitive function exacerbated by Tregs depletion. RNA-sequencing showed TLR4/myeloid differentiation marker 88 (MyD88) as the central molecules in Tregs-pyroptosis pathway, and refraining TLR4/MyD88/NF-\u03baB pathway alleviated the aggravated pyroptosis induced by Tregs depletion. In conclusion, our findings for the first time indicate that Tregs alleviate myelin loss and improve cognitive function by inhibiting pyroptosis in microglia via TLR4/MyD88/NF-\u03baB pathway in LPC-induced demyelination.\n\nID: 36766838\nTitle: Prothymosin \u03b1 Plays Role as a Brain Guardian through Ecto-F1 ATPase-P2Y12 Complex and TLR4/MD2.\nAbstract: Prothymosin alpha (ProT\u03b1) was discovered to be a necrosis inhibitor from the conditioned medium of a primary culture of rat cortical neurons under starved conditions. This protein carries out a neuronal cell-death-mode switch from necrosis to apoptosis, which is, in turn, suppressed by a variety of neurotrophic factors (NTFs). This type of NTF-assisted survival action of ProT\u03b1 is reproduced in cerebral and retinal ischemia-reperfusion models. Further studies that used a retinal ischemia-reperfusion model revealed that ProT\u03b1 protects retinal cells via ecto-F1 ATPase coupled with the Gi-coupled P2Y12 receptor and Toll-like receptor 4 (TLR4)/MD2 coupled with a Toll-IL-1 receptor domain-containing adaptor inducing IFN-\u03b2 (TRIF). In cerebral ischemia-reperfusion models, ProT\u03b1 has additional survival mechanisms via an inhibition of matrix metalloproteases in microglia and vascular endothelial cells. Heterozygous or conditional ProT\u03b1 knockout mice show phenotypes of anxiety, memory learning impairment, and a loss of neurogenesis. There are many reports that ProT\u03b1 has multiple intracellular functions for cell survival and proliferation through a variety of protein-protein interactions. Overall, it is suggested that ProT\u03b1 plays a key role as a brain guardian against ischemia stress through a cell-death-mode switch assisted by NTFs and a role of neurogenesis.\n\nID: 36765034\nTitle: IRAK-M suppresses the activation of microglial NLRP3 inflammasome and GSDMD-mediated pyroptosis through inhibiting IRAK1 phosphorylation during experimental autoimmune encephalomyelitis.\nAbstract: The activation of the NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) inflammasome triggers pyroptosis proinflammatory cell death in experimental autoimmune encephalomyelitis (EAE). However, the underlying mechanisms of the inflammatory processes of microglia in EAE remain unclear. Our previous studies suggested that interleukin-1 receptor-associated kinase (IRAK)-M down-regulates the toll-like receptor 4/interleukin-1 receptor signaling pathway. Here, we used IRAK-M knockout (IRAK-M-/-) mice and their microglia to dissect the role of IRAK-M in EAE. We found that deletion of IRAK-M increased the incidence rate and exacerbated the clinical symptoms in EAE mice. We then found that IRAK-M deficiency promoted the activation of microglia, activated NLRP3 inflammasomes, and enhanced GSDMD-mediated pyroptosis in the microglia of EAE. In contrast, over-expression of IRAK-M exerted inhibitory effects on neuroinflammation, NLRP3 activation, and pyroptosis. Moreover, IRAK-M deficiency enhanced the phosphorylation of IRAK1, while IRAK-M over-expression downregulated the level of phosphorylated IRAK1. Finally, we found upregulated binding of IRAK1 and TNF receptor-associated factor 6 (TRAF6) in IRAK-M-/- EAE mice compared to WT mice, which was blocked in AAVIRAK-M EAE mice. Our study reveals a complex signaling network of IRAK-M, which negatively regulates microglial NLRP3 inflammasomes and pyroptosis by inhibiting IRAK1 phosphorylation during EAE. These findings suggest a potential target for the novel therapeutic approaches of multiple sclerosis (MS)/EAE and NLRP3-related inflammatory diseases.\n\nID: 36754162\nTitle: Menstrual blood-derived endometrial stem cells inhibit neuroinflammation by regulating microglia through the TLR4/MyD88/NLRP3/Casp1 pathway.\nAbstract: Neuroinflammation is a common response in various neurological disorders. Mesenchymal stem cell-based treatment has become a promising therapy for neuroinflammation-associated diseases. However, the effects of mesenchymal stem cells are controversial, and the underlying mechanism is incompletely understood. In the present study, menstrual blood-derived endometrial stem cells were intravenously transplanted into a mouse model of neuroinflammation established by peripheral injection of lipopolysaccharide. Microglial cells challenged with lipopolysaccharide were cultured with conditioned medium from endometrial stem cells. The levels of cytokines were detected by enzyme-linked immunosorbent assay. Cell proliferation and death were detected by Cell Counting Kit 8 and flow cytometry, respectively. The expression levels of Toll-like receptor 4 (TLR4), myeloid differentiation primary response gene 88 (MyD88), NLR family pyrin domain containing 3 (NLRP3) and caspase 1 (Casp1) were evaluated by western blotting. The results showed that intravenous transplantation of endometrial stem cells downregulated proinflammatory factors and upregulated anti-inflammatory factors in the brain of mice with neuroinflammation. Conditioned medium suppressed the inflammatory reaction and hyperactivation of microglial cells and protected microglial cells from cell death induced by lipopolysaccharide in vitro. The expression of TLR4, MyD88, NLRP3 and Casp1 in the brain of mice with neuroinflammation and in lipopolysaccharide-stimulated microglial cells was downregulated by endometrial stem cells and conditioned medium, respectively. These data suggested that menstrual blood-derived endometrial stem cells may suppress neuroinflammatory reactions partially by regulating microglia through the TLR4/MyD88/NLRP3/Casp1 signalling pathway. Our findings may be very useful for the development of an alternative stem cell-based therapy for neuroinflammation-associated disorders.\n\nID: 42519304\nTitle: Dynamic activation of lytic cell death-related programs identifies CD14 as a candidate hub gene associated with secondary injury after spinal cord injury.\nAbstract: Secondary spinal cord injury (SCI) involves persistent inflammation, oxidative stress, and multiple forms of programmed cell death. However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures. Key findings were further evaluated using an external human SCI-related cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and published single-cell RNA-seq data. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. External validation in a human SCI-related peripheral blood cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and single-cell reanalysis further supported the upregulation of CD14 and its association with myeloid inflammatory activation and pyroptosis-, necroptosis-, and ferroptosis-related signatures. Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI.\n\nID: 42518142\nTitle: MicroRNAs in Spinal Cord Injury: Molecular and Translational Insights.\nAbstract: Spinal cord injury (SCI) is characterized by complex molecular and cellular disturbances that contribute to progressive tissue damage and neurological dysfunction. Among the regulatory mechanisms implicated, microRNAs (miRNAs), which are small noncoding RNAs that regulate gene expression posttranscriptionally, have emerged as central components of several injury-related pathways. This review synthesizes current knowledge regarding the regulatory functions of miRNAs and evaluates their potential as therapeutic targets. Recent experimental and preclinical studies were analyzed to identify key miRNAs associated with injury-induced molecular responses and to assess advances in miRNA-based therapeutic strategies, including the use of miRNA mimics, inhibitors, and delivery systems. Several miRNAs, including miR-21, miR-223, miR-124, and miR-219, can regulate essential biological processes such as apoptosis, neuroinflammation, oxidative stress, glial activation, and remyelination. miR-21 and miR-223 exhibited context-dependent roles in neuroinflammation, apoptosis, and vascular repair, while miR-124 could modulate microglial activity and miR-219 facilitates oligodendrocyte differentiation and myelin restoration. Experimental therapeutic approaches employing viral vectors, nanoparticles, stem cell-based delivery, and exosome systems have resulted in enhanced tissue preservation, angiogenesis, and functional outcomes in preclinical models. miRNAs serve as critical molecular regulators and represent promising therapeutic targets. Nevertheless, clinical translation is constrained by challenges such as delivery barriers, off-target effects, and the complexity of miRNA-mediated regulatory networks. Advances in delivery technologies and research focused on precise miRNA regulation may support the development of effective neuroprotective and regenerative therapies.\n\nID: 42517904\nTitle: Bioactive adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres promotes spinal cord repair by suppressing inflammation, apoptosis, oxidative stress, and ferroptosis.\nAbstract: Spinal cord injury (SCI) is a devastating neurological condition characterized by severe neuronal loss, inflammation, oxidative stress, and various forms of regulated cell death that collectively impair functional recovery. The present study aimed to develop a bioactive therapeutic platform based on an adipose-derived extracellular matrix (ECM) hydrogel incorporating cytokine-releasing PLGA microspheres to promote spinal cord repair. The hydrogel was fabricated from decellularized adipose tissue and combined with microspheres encapsulating interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and glial cell line-derived neurotrophic factor (GDNF) to achieve sustained cytokine delivery. Seventy-five male Sprague-Dawley rats were randomly allocated into five experimental groups, including control, SCI, hydrogel, microsphere, and Hydrogel\u2009+\u2009Mic groups. Tissue specimens were subsequently harvested from the lesion site for further analyses. In a rat model of SCI, treatment with the cytokine-releasing microsphere-loaded hydrogel significantly improved electrophysiological conduction and locomotor recovery compared with untreated SCI animals and groups receiving individual treatments. Molecular analyses demonstrated that the combined treatment markedly suppressed the expression of pro-inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Additionally, apoptosis-related markers showed substantial modulation, characterized by decreased Caspase-3 and Bax expression and increased Bcl-2 levels. The therapy also improved the oxidative balance by increasing antioxidant markers including GSH, SOD, and CAT while reducing the lipid peroxidation marker MDA. Furthermore, ferroptosis-associated biomarkers were significantly regulated, with elevated levels of GSH, GPX4, and SLC7A11 and reduced ACSL4 expression. Histological analyses revealed significant preservation of spinal cord architecture, reduced cavity formation, enhanced neuronal survival, and decreased glial activation in animals treated with the composite hydrogel system. Collectively, these findings demonstrate that adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres provides a multifunctional therapeutic strategy that attenuates inflammation, apoptosis, oxidative stress, and ferroptosis, ultimately promoting structural and functional recovery following spinal cord injury.\n\nID: 42510583\nTitle: Omega-3 Fatty Acids Attenuate Neuropathic Pain by Modulating Ferroptotic Stress, Selenoamino Acid Metabolism, and Lipid Remodeling.\nAbstract: Neuropathic pain (NP) arises from diverse conditions, including peripheral nerve injury, spinal cord injury (SCI), and painful diabetic neuropathy, yet these disorders share oxidative stress, mitochondrial dysfunction, lipid dysregulation, and altered neuronal excitability. We investigated whether dietary omega-3 polyunsaturated fatty acids modulate ferroptotic stress-associated pathways, defined as lipid peroxidation susceptibility and impaired antioxidant defense rather than overt ferroptotic cell death. Female Sprague-Dawley rats received either a soy oil control diet (SOD) or fish oil omega-3-enriched diet (FOD) before chronic constriction injury (CCI). Behavioral outcomes were assessed using Hargreaves and CatWalk testing, followed by dorsal root ganglion (DRG) RNA sequencing, RT-PCR, and GPX4 ELISA. Previously generated SCI metabolomics and human diabetic serum metabolomic/lipidomic datasets were re-analyzed for shared pathways. FOD attenuated CCI-induced thermal hypersensitivity and improved gait parameters. DRG transcriptomics showed reduced injury-associated transcriptional disruption, enrichment of selenoamino acid metabolism, nonsense-mediated decay, and ribosomal quality-control pathways, and reduced mitochondrial dysfunction pathway activity. Omega-3 increased Gpx1/Gpx4 expression and GPX4 protein, reduced pain-associated genes including Scn10a, Piezo2, Trpa1, and Oprm1, and aligned with selenoamino acid enrichment in SCI and human datasets. Human lipidomics showed MG/DG/PC/PE pathway remodeling. These findings support ferroptotic stress as a plausible shared downstream mechanism modulated by omega-3 supplementation across NP models.\n\nID: 42503354\nTitle: Lgals3high Macrophages Orchestrate Neuroinflammation and Extracellular Matrix Remodelling via NF-\u03baB Pathway in Acute Spinal Cord Injury.\nAbstract: Acute spinal cord injury (ASCI) causes severe dysfunction, with secondary ECM remodelling being more destructive than primary injury. Macrophages regulate neuroinflammation and ECM remodelling in ASCI. Studies shown ECM related gene Lgals3 regulate macrophage polarization across various diseases. However, the role of Lgals3 in ASCI-related ECM remodelling and neuroinflammation remains unclear. We integrated Single-cell RNA Sequencing (ScRNA-seq) analysis with in vitro and in vivo experiments. An ECM-related gene set was constructed for bioinformatic analyses of cell clustering, pseudotime trajectory, cell-cell communication, and transcription factor activity. LPS+IFN-\u03b3-induced RAW264.7 macrophages were treated with the Lgals3 inhibitor GB1107, and the Lgals3/NF-\u03baB/p65/Ccl2 axis was further dissected by siRNA-mediated Lgals3 knockdown, pharmacological NF-\u03baB inhibition with QNZ, and TNF-\u03b1-mediated NF-\u03baB reactivation rescue. ASCI models in SD rats were assessed via multiplex immunohistochemistry (mIHC), histology, TUNEL, western blot, and qRT-PCR. Seven cell types were identified in the ASCI microenvironment, with macrophages showing the most upregulated ECM-related genes. Four ECM-associated macrophage subtypes were defined; Lgals3high macrophages (Mac-1), characterized by high Lgals3 and Ccl2 expression, dominated early-phase ASCI. Mac-1 exhibited the strongest intercellular communication with prominent CCL signalling pathway activation. Lgals3, Ccl2, and p65 were specifically upregulated in M1 macrophages post-ASCI, with p65 nuclear translocation. GB1107 inhibited NF-\u03baB, promoted M1-to-M2 polarization, reduced inflammatory infiltration and ECM remodelling, and decreased apoptosis. Mechanistically, siRNA-mediated Lgals3 silencing suppressed NF-\u03baB/p65 activation and Ccl2 expression while inducing Arg1; this phenotype was recapitulated by NF-\u03baB inhibition and reversed by TNF-\u03b1-driven NF-\u03baB reactivation, validating the Lgals3/NF-\u03baB/p65/Ccl2 axis as the obligate regulatory backbone of macrophage polarization. Lgals3high macrophages are core drivers of ECM remodelling in ASCI via a Lgals3/NF-\u03baB/p65/Ccl2 signalling axis that couples M1 polarization with monocyte recruitment. GB1107 disrupts this axis, reprograms macrophages from M1 to M2, attenuates inflammatory infiltration and ECM remodelling, and reduces apoptosis. GB1107 exerts therapeutic effects by regulating macrophage polarization and ECM remodelling, providing a novel \"immune-matrix\" dual-targeting strategy.\n\nID: 42499235\nTitle: Multiomics Profiling Identifies Tlr4 as a Therapeutic Target of Necroptosis in Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) leads to a complex cascade of cellular events, among which necroptosis plays a critical role in exacerbating neuronal injury and inflammation. In this study, we aimed to identify and validate key genes associated with necroptosis in SCI using bulk RNA-seq data, followed by differential analysis and weighted gene coexpression network analysis (WGCNA). We identified several candidate necroptosis-related genes, and further least absolute shrinkage and selection operator (LASSO) regression highlighted five SCI-necroptosis differentially expressed genes (DEGs): toll-like receptor 4 (Tlr4), Nlrp3, Il1b, Tnfaip3, and Stat4. These genes were validated using RT-qPCR and western blot experiments. Our analysis revealed that necroptosis scores were significantly elevated following SCI. Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) analysis revealed that Tlr4 was upregulated in myeloid cells (microglia and macrophages) and played a pivotal role in triggering downstream necroptosis, which was confirmed by protein levels. In vitro and in vivo experiments confirmed that Tlr4 inhibition attenuated necroptosis and inflammation. This study is the first to establish Tlr4 as a direct upstream regulator of the pRIPK1/pRIPK3/pMLKL necroptotic axis in SCI, distinct from its role as a general inflammatory mediator, suggesting Tlr4 as a promising therapeutic target for functional recovery.\n\nID: 42486345\nTitle: Novel role of GADD45A in synergistic regulation of neuronal ferroptosis and apoptosis after spinal cord injury via NF-\u03baB signaling.\nAbstract: Ferroptosis and apoptosis are major mechanisms of neuronal injury after spinal cord injury (SCI), but regulators that coordinate both processes remain poorly defined. In this study, we analyzed 188 ferroptosis-related differentially expressed genes (FRDEGs) at 7\u00a0day (7d) after SCI and identified GADD45A as a central gene in the post-SCI ferroptosis network, with a functional profile closely linked to apoptosis. GADD45A was markedly upregulated in injured spinal cord tissue. In vivo, GADD45A knockdown improved neurological recovery and promoted tissue repair by modulating markers of ferroptosis and apoptosis. In H2O2-treated PC12 cells, GADD45A knockdown reduced the expression of Cleaved Caspase-3, BAX, Cleaved Caspase-9, 4-HNE, and ACSL4, while increasing the expression of BCL-2, GPX4, FTH1, and FPN. It also attenuated H2O2-induced cellular injury. Mechanistically, GADD45A knockdown inhibited NF-\u03baB signaling and reduced nuclear translocation of NF-\u03baB-p65. These protective effects were reversed by the NF-\u03baB activator CU-T12-9. Collectively, these findings suggest that GADD45A promotes neuronal ferroptosis and apoptosis after SCI by regulating the NF-\u03baB pathway, and that GADD45A may be a potential therapeutic target for SCI.\n\nID: 42479245\nTitle: Seipin modulates Alzheimer's disease pathogenesis by regulating ferroptosis through a glycine-mediated metabolic pathway.\nAbstract: Alzheimer's disease (AD) remains an incurable neurodegenerative disorder with an elusive pathogenesis, where emerging evidence implicates metabolic dysregulation and ferroptosis in neuronal loss. Although the BSCL2 gene, which encodes Seipin, is crucial for lipid metabolism, its specific role in the progression of AD remains undefined. This study employed Mendelian randomization (MR) analysis, in vivo APP/PS1 mouse models, and in vitro BV2 microglial assays to elucidate the mechanistic axis linking BSCL2, metabolites, and ferroptosis in AD. MR analysis demonstrated a causal relationship between genetically predicted elevated BSCL2 expression and an increased risk of AD, partially mediated by glycine. Supporting these genetic findings, stereotactic knockdown of Seipin in the hippocampus of APP/PS1 mice significantly ameliorated cognitive deficits without inducing systemic metabolic toxicity. Mechanistically, Seipin deficiency reduced ferroptosis in both AD mouse brains and A\u03b2-stimulated microglia, as evidenced by the upregulation of anti-ferroptotic markers (GPX4, Nrf2, HO-1) and the suppression of pro-ferroptotic effectors (ACSL4, NCOA4). Moreover, glycine supplementation partially ameliorated the aggravated ferroptotic phenotype caused by Seipin overexpression, indicating a functional feedback mechanism in which glycine facilitates glutathione synthesis to mitigate Seipin-induced lipid peroxidation. These findings collectively identify Seipin as a novel regulator of ferroptosis in the pathogenesis of AD and underscore the potential of the BSCL2-glycine-ferroptosis axis as a therapeutic target. Future research should aim to elucidate the specific molecular interactions between Seipin and the iron-handling machinery and to validate glycine-based interventions in clinical settings as a means to prevent neurodegeneration.\n\nID: 42477269\nTitle: Betulinic Acid Promotes Motor Function Recovery After Spinal Cord Injury by Inhibiting Apoptosis Through Myc/NF-\u03baB Signaling Pathway.\nAbstract: Spinal cord injury (SCI) imposes a remarkable burden on affected cases and their families, while current treatment options remain insufficient. This study aimed to identify and validate the molecular targets, signaling pathways, and mechanisms by which Betulinic acid (BA) exerts its therapeutic effects on SCI, providing new directions for clinical intervention. In vivo, Kunming mice underwent behavioral tests, Nissl staining, and Hematoxylin-eosin staining to evaluate motor function recovery and determine the expression levels of relevant biomarkers. Bioinformatics analyses were employed to investigate the genes involved in the SCI-BA interaction, elucidating key signaling pathways, followed by molecular docking of potential target genes. In vitro, lipopolysaccharide was used to induce a secondary SCI condition in cultured astrocytes, enabling the evaluation of BA's effects on inflammatory and apoptotic responses. The results demonstrated that BA could significantly promote motor function recovery and reduce the expression levels of inflammation-related cytokines, including IL-1\u03b2, IL-6, and TNF-\u03b1, in SCI mice. Through bioinformatics analysis, Myc was identified as a key target of BA in SCI, and NF-\u03baB and apoptosis pathways could be implicated in its mechanism of action. Both in vitro and in vivo experiments confirmed that BA could target Myc to modulate the inflammatory response in astrocytes, reducing the activation of RELA and MAPK14. In conclusion, these findings indicate that BA attenuates neuroinflammation and apoptosis via Myc and the NF-\u03baB signaling pathway, thereby promoting functional recovery following SCI.\n\nID: 42464547\nTitle: [Mechanisms of Piezo1-mediated microglial ferroptosis in inhibiting spinal cord injury repair].\nAbstract: To investigate the mechanism of the mechanosensitive ion channel Piezo1 in microglial ferroptosis following spinal cord injury (SCI), and to assess the effects of Piezo1 inhibition on ameliorating the injury microenvironment and promoting neurological functional recovery. Primary microglia cells were extracted from neonatal 1-2 days C57BL/6 mice and divided into control group, Yoda1 (Piezo1 agonist) group, and Yoda1+GsMTx4 (Piezo1 inhibitor) group. Live/dead cell staining, reactive oxygen species (ROS) fluorescence staining, 5, 5', 6, 6'-tetrachloro-1, 1', 3, 3'-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) mitochondrial membrane potential detection, and transmission electron microscopy were utilized to assess microglial ferroptosis and mitochondrial functional characteristics. SPF female C57BL/6 mice aged 6 to 8 weeks were used to detect the expression of Piezo1 at different time points after SCI by Western blot, and the two time points with no significant change and the most significant change in Piezo1 expression after SCI were selected for subsequent experiments. T 8, T 9 SCI models were established by modified Allen's method, and were divided into sham operation group, injury group, and injury+shPiezo1 group (Piezo1-targeted interfering virus AAV-shPiezo1 was injected in situ to knock down the expression of Piezo1 14 days before modeling). Colocalization of Piezo1 with microglial markers purinergic receptor P2Y12 (P2ry12), and the expressions of glutathione peroxidase 4 (GPX4) and acyl coenzyme A synthetase long chain member 4 (ACSL4) were observed by immunofluorescence staining. Basso Mouse Scale (BMS) score was used to assess hindlimb motor function in mice. The level of ROS was detected by dihydroethidium (DHE) staining; the content of malondialdehyde (MDA) was detected by MDA kit; the levels of tumor necrosis factor \u03b1 (TNF-\u03b1) and interleukin 10 (IL-10) were detected by ELISA assay; the pathological morphology of spinal cord was observed by HE staining. In vitro experiments showed that compared with the control group, the Yoda1 group had typical ultrastructural changes of ferroptosis, such as increased microglial cell death, enhanced ROS fluorescence, mitochondrial membrane potential depolarization, mitochondrial shrinkage and mitochondrial cristae breakage (all P<0.05), while the GsMTx4 group could partially reverse the above effects ( P<0.05). In vivo experiments demonstrated that the expression of Piezo1 in spinal cord tissue was up-regulated sequentially after SCI, and reached the peak on the 7th day after SCI ( P<0.05), and it was mainly localized in P2ry12-positive microglia. Compared with the injury group, in the injury+shPiezo1 group, the expression of ferroptosis core protein GPX4 in microglia was increased, the expression of ACSL4 was decreased, the levels of ROS and MDA in spinal cord tissue were decreased ( P<0.05), the level of pro-inflammatory factor TNF-\u03b1 was decreased, and the level of anti-inflammatory factor IL-10 was increased ( P<0.05). In addition, the BMS score was significantly higher than that of the injury group ( P<0.05) from the 14th day after operation, and the spinal cord tissue structure was relatively well preserved, and the cavity area was reduced. SCI activates the Piezo1 channel in microglia, triggering mitochondrial dysfunction and mediating cellular ferroptosis, thereby aggravating secondary neuroinflammation. Targeted inhibition of Piezo1 effectively blocks the ferroptosis process, ameliorates the immune microenvironment, and promotes tissue repair and locomotor functional recovery after SCI. \u63a2\u7a76\u673a\u68b0\u654f\u611f\u6027\u79bb\u5b50\u901a\u9053Piezo1\u5728\u810a\u9ad3\u635f\u4f24\uff08spinal cord injury\uff0cSCI\uff09\u540e\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u4e2d\u7684\u4f5c\u7528\u673a\u5236\uff0c\u5e76\u8bc4\u4f30\u6291\u5236Piezo1\u5bf9\u6539\u5584\u635f\u4f24\u5fae\u73af\u5883\u53ca\u4fc3\u8fdb\u795e\u7ecf\u529f\u80fd\u6062\u590d\u7684\u5f71\u54cd\u3002. \u63d0\u53d6\u65b0\u751f1\uff5e2 d C57BL/6\u5c0f\u9f20\u539f\u4ee3\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001Yoda1\uff08Piezo1\u6fc0\u52a8\u5242\uff09\u7ec4\u53caYoda1+GsMTx4\uff08Piezo1\u6291\u5236\u5242\uff09\u7ec4\u3002\u5229\u7528\u6d3b\u6b7b\u7ec6\u80de\u67d3\u8272\u3001\u6d3b\u6027\u6c27\uff08reactive oxygen species\uff0cROS\uff09\u8367\u5149\u67d3\u8272\u30015\uff0c5\u2019\uff0c6\uff0c6\u2019-\u56db\u6c2f-1\uff0c1\u2019\uff0c3\uff0c3\u2019-\u56db\u4e59\u57fa\u82ef\u5e76\u54aa\u5511\u78b3\u82b1\u9752\u7898\u5316\u7269\uff085\uff0c5\u2019\uff0c6\uff0c6\u2019-tetrachloro-1\uff0c1\u2019\uff0c3\uff0c3\u2019-tetraethylbenzimidazolylcarbocyanine iodide\uff0cJC-1\uff09\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u68c0\u6d4b\u53ca\u900f\u5c04\u7535\u955c\u89c2\u5bdf\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u53ca\u7ebf\u7c92\u4f53\u529f\u80fd\u7279\u5f81\u3002\u53d66\uff5e8\u5468\u9f84SPF\u7ea7\u96cc\u6027C57BL/6\u5c0f\u9f20\uff0c\u91c7\u7528Western blot\u68c0\u6d4bPiezo1\u5728SCI\u540e\u4e0d\u540c\u65f6\u95f4\u70b9\u7684\u8868\u8fbe\u89c4\u5f8b\uff0c\u9009\u53d6\u635f\u4f24\u540ePiezo1\u8868\u8fbe\u672a\u89c1\u660e\u663e\u6539\u53d8\u53ca\u53d8\u5316\u6700\u663e\u8457\u76842\u4e2a\u65f6\u95f4\u70b9\u8fdb\u884c\u540e\u7eed\u5b9e\u9a8c\u3002\u91c7\u7528\u6539\u826fAllen\u6cd5\u5236\u5907T 8\u3001T 9 SCI\u6a21\u578b\uff1b\u5b9e\u9a8c\u5206\u4e3a\u5047\u624b\u672f\u7ec4\u3001\u635f\u4f24\u7ec4\u548c\u635f\u4f24+shPiezo1\u7ec4\uff08\u9020\u6a21\u524d14 d\u539f\u4f4d\u6ce8\u5c04\u9776\u5411Piezo1\u7684\u5e72\u6270\u75c5\u6bd2AAV-shPiezo1\u4ee5\u6572\u4f4ePiezo1\u8868\u8fbe\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u89c2\u5bdfPiezo1\u4e0e\u5c0f\u80f6\u8d28\u7ec6\u80de\u6807\u5fd7\u7269\u560c\u5464\u80fd\u53d7\u4f53P2Y12\uff08purinergic receptor P2Y12\uff0cP2ry12\uff09\u7684\u5171\u5b9a\u4f4d\u53ca\u8c37\u80f1\u7518\u80bd\u8fc7\u6c27\u5316\u7269\u91764\uff08glutathione peroxidase 4\uff0cGPX4\uff09\u3001\u9170\u57fa\u8f85\u9176A\u5408\u6210\u9176\u957f\u94fe\u5bb6\u65cf\u6210\u54584\uff08acyl coenzyme A synthetase long chain member 4\uff0cACSL4\uff09\u7684\u8868\u8fbe\uff1bBasso Mouse Scale\uff08BMS\uff09\u8bc4\u5206\u8bc4\u4f30\u5c0f\u9f20\u540e\u80a2\u8fd0\u52a8\u529f\u80fd\uff1b\u4e8c\u6c22\u4e59\u952d\uff08dihydroethidium\uff0cDHE\uff09\u67d3\u8272\u68c0\u6d4b\u7ec4\u7ec7ROS\u6c34\u5e73\uff1b\u4e19\u4e8c\u919b\uff08malondialdehyde\uff0cMDA\uff09\u8bd5\u5242\u76d2\u68c0\u6d4bMDA\u542b\u91cf\uff1bELISA\u68c0\u6d4b\u708e\u75c7\u56e0\u5b50TNF-\u03b1\u3001IL-10\u6c34\u5e73\uff1bHE\u67d3\u8272\u89c2\u5bdf\u810a\u9ad3\u7ec4\u7ec7\u75c5\u7406\u5f62\u6001\u3002. \u4f53\u5916\u5b9e\u9a8c\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cYoda1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u6b7b\u4ea1\u589e\u591a\u3001ROS\u8367\u5149\u589e\u5f3a\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u53bb\u6781\u5316\u3001\u7ebf\u7c92\u4f53\u51fa\u73b0\u76b1\u7f29\u53ca\u5d74\u65ad\u88c2\u7b49\u94c1\u6b7b\u4ea1\u5178\u578b\u8d85\u5fae\u7ed3\u6784\u6539\u53d8\uff08\u5747 P<0.05\uff09\uff1b\u800cGsMTx4\u7ec4\u53ef\u90e8\u5206\u9006\u8f6c\u4e0a\u8ff0\u6548\u5e94\uff08 P<0.05\uff09\u3002\u4f53\u5185\u5b9e\u9a8c\u793a\uff0cSCI\u540e\u810a\u9ad3\u7ec4\u7ec7\u4e2dPiezo1\u8868\u8fbe\u5448\u65f6\u5e8f\u6027\u4e0a\u8c03\uff0c\u672f\u540e7 d\u8fbe\u5cf0\u503c\uff08 P<0.05\uff09\uff0c\u4e14\u4e3b\u8981\u5b9a\u4f4d\u4e8eP2ry12\u9633\u6027\u5c0f\u80f6\u8d28\u7ec6\u80de\u3002\u4e0e\u635f\u4f24\u7ec4\u6bd4\u8f83\uff0c\u635f\u4f24+shPiezo1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u5185\u94c1\u6b7b\u4ea1\u6838\u5fc3\u86cb\u767dGPX4\u8868\u8fbe\u56de\u5347\u3001ACSL4\u8868\u8fbe\u4e0b\u964d\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5185ROS\u53caMDA\u6c34\u5e73\u964d\u4f4e\uff08 P<0.05\uff09\uff0c\u540c\u65f6\u4fc3\u708e\u56e0\u5b50TNF-\u03b1\u6c34\u5e73\u4e0b\u964d\u3001\u6297\u708e\u56e0\u5b50IL-10\u6c34\u5e73\u5347\u9ad8\uff08 P<0.05\uff09\uff1b\u6b64\u5916\uff0c\u81ea\u672f\u540e14 d\u8d77BMS\u8bc4\u5206\u663e\u8457\u9ad8\u4e8e\u635f\u4f24\u7ec4\uff08 P<0.05\uff09\uff0c\u4e14\u810a\u9ad3\u7ec4\u7ec7\u7ed3\u6784\u4fdd\u5b58\u76f8\u5bf9\u5b8c\u597d\uff0c\u7a7a\u6d1e\u9762\u79ef\u51cf\u5c0f\u3002.

We investigated the role of sphingosine-1-phosphate receptor 2 (S1P2 receptor) in contusive spinal cord injury and evaluated the therapeutic effects of an S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) in a rat model of SCI. The SCI model was established using a 10\u2009g weight dropped onto the T10 vertebrae in female rats. After functional testing, spinal cords were harvested for biochemical and histopathological assays at different time points. Nissl and Prussian blue staining were used to analyse neuronal death. Neuronal ferroptosis in spinal cords was examined using transmission electron microscopy, and lipid peroxidation in the cultured neurones was analysed. After SCI, S1P (Sphingosine 1-phosphate) was released from crushed spinal cords and subsequently activated the neuronal S1P2 receptor to increase lipid peroxidation, which injured neurones via inducing neuronal ferroptosis through the P-ERK/ERK/ACSL4 pathway, resulting in limb paralysis. S1P2 receptor inhibition significantly blocked S1P2 receptor activation and attenuated neuronal ferroptosis. Thus, S1P2 receptor was a therapeutic target for the treatment of SCI. Systemic administration of the S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) effectively promoted locomotor function recovery by attenuating neuronal ferroptosis in rat spinal cords. S118 impeded neuronal ferroptosis by inhibiting lipid peroxidation. Contusive SCI is characterised by neuronal loss due to S1P2 receptor activation in spinal neurones. S1P2 receptor activation increases lipid peroxidation, which induces neuronal ferroptosis. S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) improves locomotor functional recovery by preserving the spinal cord structure after SCI.\n\nID: 42431350\nTitle: Development and characterization of a novel transgenic strain to selectively label neurons that degenerate in 5xFAD mice.\nAbstract: This paper describes a novel double transgenic-based platform developed by crossing a murine model of Alzheimer's disease (AD), 5xFAD mice with RosatdTomato (tdT) reporter mice, to track degeneration of specific populations of neurons. 5xFAD+/-/RosatdT mice received intra-spinal cord injections of AAV-retrograde (rg)/Cre at 2-4\u00a0months of age to retrogradely transduce and induce tdT expression by corticospinal neurons (CSNs) in layer V of the sensorimotor cortex as well as neurons in the red nucleus and reticular formation that project to the spinal cord. Brains and spinal cords were collected 2-3\u00a0weeks post-injection or between 6-10 and 11-15\u00a0months of age. Immunohistochemical studies of transgene expression throughout the brain and spinal cord using an antibody selective for human APP (hAPP) revealed age-dependent accumulation of clusters of hAPP-positive granules in areas containing hAPP-labeled neuronal cell bodies. Surprisingly, there were also hAPP-positive granules in regions containing axons and synaptic terminals from hAPP expressing neurons. Moreover, tdT expressed by CSNs accumulated in the same granules as hAPP, and both tdT and hAPP were present in clusters of granules with other markers of AD pathology. Quantitative assessments confirmed age-related degeneration of layer V CSNs accompanied by progressive accumulation of clusters of tdT and hAPP-positive granules. Overall, our results indicate that accumulation of aggregated hAPP in areas containing axons and synaptic terminals from hAPP expressing neurons is a prominent feature of AD pathophysiology in 5xFAD mice and that accumulation of clusters of hAPP granules provides a secondary measure to track neurodegeneration of identified populations of genetically labeled neurons.\n\nID: 42426407\nTitle: MANF safeguards mitochondria-associated endoplasmic reticulum membrane integrity in nucleus pulposus-derived mesenchymal stem cells to maintain homeostasis of the intervertebral disc.\nAbstract: Intervertebral disc (IVD) degeneration (IDD) is a leading cause of low back pain, with limited treatment options. The degenerative disc's harsh microenvironment promotes nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) death and hinders self repair. Mesencephalic astrocyte-derived neurotrophic factor (MANF), an atypical neurotrophic factor, has protective effects in degenerative diseases. However, its role in IDD is unclear. Assessment of MANF expression was conducted in both human nucleus pulposus tissues and a rat IVD puncture model. An in vitro model of degeneration was established by acid treatment of NP-MSCs, and the functional role of MANF was explored through its knockdown and overexpression. RNA sequencing was employed to identify downstream targets. The therapeutic potential of MANF-overexpressing NP-MSCs was evaluated in a rat puncture model. MANF expression was markedly downregulated in degenerated IVD tissues from both human patients and rat models. Correspondingly, in vitro experiments demonstrated that MANF knockdown exacerbated, while its overexpression mitigated, acid-induced apoptosis of NP-MSCs. Mechanistically, MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity, as demonstrated by the complete abolition of this protection upon treatment with the MAM uncoupler FATE1. Transcriptomic analysis and subsequent validation identified receptor expression-enhancing protein 1 (REEP1) as a critical downstream effector through which MANF safeguards MAM integrity. We further elucidated that MANF upregulates REEP1 expression by directly inhibiting miR-33b-5p. In vivo, transplantation of MANF-overexpressing NP-MSCs effectively attenuated IDD in a rat model. MANF protected NP-MSCs from acidosis by sustaining MAM integrity via the MiR-33b-5p/REEP1 axis. These findings reveal MANF's mechanism and therapeutic potential for IDD.\n\nID: 42422221\nTitle: Esculentoside A mitigates oxidative stress and neuronal apoptosis in spinal cord injury by modulating the Nrf2/HO-1 pathway.\nAbstract: Spinal cord injury (SCI) is a profoundly disabling condition affecting the central nervous system. Neuronal apoptosis constitutes a critical pathological event leading to neurological dysfunctions, which is further exacerbated by oxidative stress following SCI. Esculentoside A (EsA), a bioactive saponin isolated from Phytolaca esculenta, exhibits neuroprotective potential in our preliminary studies. However, whether EsA attenuates oxidative stress and neuronal apoptosis in SCI remains unclear. The current study aimed to investigate the protective potential of EsA against oxidative stress and neuronal apoptosis following SCI, and to elucidate the associated molecular mechanisms. SCI was modeled in rats via contusion using the PSI-IH 0400 Striker impactor, and rats were treated intraperitoneally with 10 mg/kg EsA once daily. The Basso, Beattie, and Bresnahan (BBB) scale, grid walk analysis, and footprint test were adopted to evaluate motor function dynamically. Histopathological alterations in spinal cord tissue were examined by Hematoxylin-eosin (HE), Luxol Fast Blue (LFB), and Nissl staining. Oxidative stress markers, including hydrogen peroxide (H2O2) and malondialdehyde (MDA), along with antioxidant enzymes glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD), were quantified in spinal cord homogenates using commercial assay kits. Western blot, immunofluorescence staining, and molecular docking were employed to investigate the underlying mechanisms. EsA significantly improved motor function and reduced histopathological damage in SCI rats. This neuroprotective effect was accompanied by a significant improvement in oxidative stress biomarkers and neuronal apoptosis in the injured spinal cord, coinciding with activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. In conclusion, EsA exerts a neuroprotective effect against SCI by modulating oxidative stress and neuronal apoptosis partially through activation of the Nrf2/HO-1 pathway, indicating its promise as a therapeutic agent for SCI.\n\nID: 42406829\nTitle: Association of Serum lncRNA CASC11 with Injury Severity and Inflammation in Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) is a severe central nervous system trauma. This single-center, observational and in vitro study investigated the diagnostic potential of CASC11 and its possible regulatory mechanism in SCI\u00a0using clinical serum samples and lipopolysaccharide-stimulated cell models. CASC11, miR-130b-5p, and SPP1 levels were measured by real-time quantitative polymerase chain reaction (RT-qPCR). Cellular functions and targeting relationships were assessed via cell counting kit-8 (CCK-8), flow cytometry, western blot, enzyme-linked immunosorbent assay (ELISA), dual-luciferase reporter, and RNA immunoprecipitation (RIP) assays. CASC11 was highly expressed in SCI and associated with inflammation as a potential diagnostic biomarker. In lipopolysaccharide (LPS)-treated PC-12 cells, silencing CASC11 alleviated suppressed cell activity, apoptosis, and inflammation, which was reversed by miR-130b-5p inhibitor. These findings suggest that CASC11 is associated with SCI severity, while in vitro data indicate its involvement in inflammatory and apoptotic responses through the CASC11/miR-130b-5p/SPP1 axis. This study is limited by its single-center design and lack of in vivo validation.\n\nID: 42404113\nTitle: The role of microglial Tim-3 in neuroinflammation and functional recovery after spinal cord injury.\nAbstract: T-cell immunoglobulin and mucin domain-containing molecule 3 (Tim-3), an immune checkpoint molecule, is highly expressed in microglia and its expression dynamically increases during central nervous system (CNS) development. Although its immunomodulatory functions are well-established, its role in inflammation following spinal cord injury (SCI) remains unclear. This study aimed to elucidate the regulatory role of microglial Tim-3 in the sterile inflammatory response after SCI and to explore its potential as a therapeutic target. A SCI model was established using C57BL/6 mice. Microglial Tim-3 function was investigated through adeno-associated virus-mediated Tim-3 overexpression and intervention with the Nrf2 agonist Oltipraz. Luxol fast blue (LFB) and Nissl staining were used to assess lesional area and tissue structure. Basso Mouse Scale (BMS) scoring and the sucrose preference test (SPT) were employed to evaluate motor function recovery and depressive-like behavior. Immunofluorescence was performed to analyze glial activation and neurodegeneration. Expression levels of inflammatory factors were measured by enzyme-linked immunosorbent assay (ELISA) and western blot (WB). Microglia-specific Tim-3 overexpression promoted microglial proliferation and activation, inducing upregulation of iNOS and robust production of pro-inflammatory cytokines. This exacerbated neural tissue damage and motor dysfunction, whereas depressive-like behaviors were not significantly affected. These effects were partially reversed by the Nrf2 agonist. AAV-mediated microglial Tim-3 overexpression exacerbates neuroinflammation and functional impairment after SCI, potentially through an association with the Nrf2/HMGB1 signaling axis. Targeting microglial Tim-3 may represent a promising therapeutic strategy for SCI.\n\nID: 42403480\nTitle: The ferroptosis-mediated domino effect: metabolic crosstalk from intervertebral disc degeneration to spinal deformity and cord injury: a mini review.\nAbstract: Spinal degeneration, spinal deformity, and spinal cord injury (SCI) are classically managed as discrete biomechanical or neurological entities. However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse.\n\nID: 42401982\nTitle: PBAE nanoparticle-mediated delivery of ASCL1 and NGN2 genes for astroglia-to-neuron reprogramming to remodel glial scar for spinal cord injury repair.\nAbstract: Irreversible loss of neuronal cells elicited by neurotraumatic injuries or neurodegenerative disorders is particularly devastating due to the limited regenerative capacity of the central nervous system (CNS). Cell reprogramming-based therapies have emerged as promising therapeutic avenues for neuronal replenishment. However, their therapeutic potential in neural regeneration still faces formidable challenges, including risks of viral vector gene delivery, potential damage from cell transplantation, and significant glial scar (GS) formation following CNS injury. Therefore, developing an optimal approach that simultaneously replaces lost neurons and overcomes these persistent obstacles is crucial for neural regeneration and functional recovery. We engineered a non-viral gene delivery platform using biodegradable poly(\u03b2-amino ester) (PBAE) nanoparticles (NPs) to effectively co-deliver plasmids encoding proneural transcription factors ASCL1 and NGN2 directly to astroglia (ATG) within GS region, in combination with neural induction. The biochemical and physiological properties of reprogrammed ATGs were characterized both in vivo and in vitro. The therapeutic potential of PBAE-A/N delivery was assessed in spinal cord injury (SCI) animal models through behavioral evaluations. Finally, the molecular mechanisms underlying ASCL1/NGN2-mediated ATG-to-neuron reprogramming were investigated. PBAE-mediated delivery of ASCL1/NGN2 plasmids effectively reprogrammed resident ATGs within GSs into functional neurons, as evidenced by the acquisition of neuronal morphology and biochemical phenotype (neuronal marker expression), loss of ATG characteristics, scar remodeling, and functionality indistinguishable from those of genuine neurons, including specialized calcium signaling, synaptic activity, and action potential firing. Critically, local administration of PBAE-ASCL1/NGN2 NPs into the GS region of the injured spinal cord significantly ameliorated neurological deficits. Mechanistically, this reprogramming event likely involved the modulation of downstream targeting signaling mediated by Cend1, RanBPM, and Dyrk1, along with crosstalk with the Notch1/Cyclin D1 axis. This study demonstrates that PBAE-mediated ASCL1/NGN2 delivery enables in situ reprogramming of ATG into functional neurons while actively dissolving GSs, thereby addressing both neuronal loss and GS barriers in CNS repair. The identified Cend1/RanBPM/Dyrk1 signaling and its crosstalk with Notch1/Cyclin D1 axis provide mechanistic insights into the events. Collectively, this work presents a novel therapeutic alternative for CNS repair and neurodegeneration by simultaneously replacing lost neurons and eliminating endogenous GSs through in situ cell reprogramming.\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: 42398338\nTitle: MiR-425-5p modulation of CREB1 affects inflammatory response and motor recovery after spinal cord injury.\nAbstract: This study aimed to investigate whether miR-425-5p contributes to post-spinal cord injury (SCI) inflammation and motor dysfunction by targeting CREB1. SCI rat models and H2O2-treated C8-D1A/C8-B4 cellular models were established. miR-425-5p and CREB1 were manipulated using inhibitors/antagomirs and siRNAs. Expression levels of miR-425-5p, IL-6, IL-1\u03b2, TNF-\u03b1, CREB1, and caspase-3 were measured using RT-qPCR. Cell apoptosis was evaluated by flow cytometry. Western blot analysis was performed to assess total CREB1 (t-CREB1) and phosphorylated CREB1 (p-CREB1) levels. Bioinformatics predictions were used to determine the targeting relationship between miR-425-5p and CREB1. BBB locomotor rating scale was employed to quantify motor function recovery in rats. miR-425-5p expression was markedly up-regulated in the H2O2-induced cell model, whereas CREB1 was down-regulated. CREB1 is a target of miR-425-5p. Inhibition of miR-425-5p significantly reduced apoptosis, suppressed pro-inflammatory cytokine expression, thereby promoting motor recovery; these effects were partially reversed by CREB1 knockdown. In SCI rats, miR-425-5p antagomir treatment alleviated inflammation and promoted motor function recovery; these beneficial effects were partially suppressed by co-administration of si-CREB1 to knockdown CREB1. MiR-425-5p upregulation in SCI directly suppresses CREB1 expression, subsequently exacerbating neuroinflammation, which in turn impairs functional recovery.\n\nID: 42393750\nTitle: Microglial checkpoint collapse in Alzheimer's disease: a tri-axial framework for biomarker-informed neuroimmune therapy.\nAbstract: Anti-amyloid antibodies have validated amyloid-\u03b2 (A\u03b2) as a disease-relevant target in Alzheimer's disease (AD), but their modest clinical effect, efficacy largely restricted to early disease, and amyloid-related imaging abnormalities (ARIA) indicate that A\u03b2 removal alone does not resolve the glial, lipid, and inflammatory programmes that sustain neurodegeneration. Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.\n\nID: 42390651\nTitle: Electroacupuncture-modulated DHCR24 facilitates spinal cord injury recovery by attenuating apoptosis and neuroinflammation via the Wnt signaling pathway.\nAbstract: Spinal cord injury (SCI) is a highly disabling condition affecting the central nervous system (CNS). Neuroinflammation and neuronal apoptosis are two critical factors in the pathological process of SCI. Although electroacupuncture (EA) has been reported to alleviate neuroinflammation in brain injury, the underlying molecular mechanism remains unclear. Transcriptome sequencing of spinal cord tissues was performed to identify potential key factors and pathways involved in EA post-SCI. DHCR24, a cholesterol synthesis regulator, was selected as a key candidate and DHCR24 was downregulated after SCI (log2FC = -1.6, P\u2009<\u20090.01), and this downregulation was notably reversed by EA treatment (log2FC\u2009=\u20091.04, P\u2009<\u20090.01). We investigated the neuroprotective effect of DHCR24 against neuron death and neuroinflammation in SCI, with a particular focus on its effects on the Wnt signaling pathway. SCI-induced DHCR24 downregulation was associated with decreased expression of the axonal regeneration marker NF and increased activation of Iba1/CCR7-positive microglia, accompanied by enhanced neuronal apoptosis and inflammatory factor release. Importantly, functional validation experiments demonstrated that DHCR24 was required for the therapeutic effects of EA. Complementary in vitro studies in LPS/IFN-\u03b3-stimulated BV2 microglia cells confirmed the role of DHCR24 in microglial polarization and neuronal survival, likely via Wnt signaling activation. Integrating transcriptomic and mechanistic evidence, we demonstrate that DHCR2 promotes Wnt pathway activation, reduces neuronal apoptosis and neuroinflammation, and ultimately enhances spinal cord repair. This study provides evidence supporting the potential clinical application of EA in SCI recovery and identifies DHCR24 may be a key mechanistic target underlying its therapeutic effects.\n\nID: 42388246\nTitle: A translational preclinical strategy for chronic spinal cord injury: neuroprotective and regenerative potential of botulinum neurotoxin type A combined with muscle atrophy prevention via electrostimulation.\nAbstract: Spinal cord injury (SCI) triggers persistent neuroinflammation, gliosis, neuronal loss, and demyelination, leading to motor deficits and neuropathic pain (NeP). Botulinum neurotoxin type A (BoNT/A) has shown anti-inflammatory and neuroprotective effects in acute SCI, but its potential in the chronic phase remains unclear. This study investigates whether combining BoNT/A with electrical muscle stimulation (EMS) enhances recovery in chronic SCI. Adult mice with severe thoracic SCI (paraplegic) underwent EMS (30\u00a0min/d for 10 non-consecutive days starting 3 d post-injury) or no stimulation. Fifteen days after SCI, animals received a single intrathecal injection of BoNT/A (15\u00a0pg/5\u00a0\u03bcl) or saline. Functional recovery was assessed up to 60 d as well as in moderate and mild SCI mice. NeP onset and maintenance were evaluated. Spinal cord tissue was analysed for astrocytic and microglial morphology, neuronal and oligodendroglial survival, myelin protein expression, and in vitro effects on oligodendrocyte precursor cells (OPCs). The phenotype of hindlimb muscles was evaluated through morphological and gene expression analyses. EMS was able to counteract muscle atrophy and fibrosis, and when combined with BoNT/A, also denervation. Moreover, the combination restored hindlimb motor function in chronic SCI, whereas BoNT/A or EMS alone were ineffective. NeP, a common comorbidity associated with SCI, was mitigated by BoNT/A treatment even when administered in the chronic phase. BoNT/A reduced astrocytic hypertrophy and excitatory synapse association and was associated with a morphology-based redistribution of microglial profiles toward a resting-like classification, decreased apoptosis, and increased neuronal and oligodendroglial survival. Myelin basic protein (MBP) expression was significantly elevated in vivo. In vitro, BoNT/A promoted OPC differentiation into myelinating oligodendrocytes, increased process complexity, and upregulated MBP, galactocerebroside C, proteolipid protein, and myelin oligodendrocyte glycoprotein under both proliferative and differentiating conditions. Cleaved synaptosomal-associated protein 25 colocalization with OPC confirmed direct BoNT/A internalization and activity. BoNT/A exerts neuroprotective effects in chronic SCI by reducing neuroinflammation and supporting neuronal and oligodendroglial preservation. When combined with EMS, it also promotes remyelination and improves muscle homeostasis, suggesting that early stimulation creates a permissive environment for recovery. These findings support the clinical evaluation of BoNT/A as a therapeutic strategy for chronic SCI.\n\nID: 42381706\nTitle: Pyroptosis as a novel therapeutic target in glioblastoma multiforme: Mechanisms, molecular insights, and therapeutic potential.\nAbstract: Glioblastoma multiforme (GBM) is the most malignant type of primary brain tumor. Its clinical management is challenging due to its heterogeneity, highly malignant nature, and insensitivity to standard treatments. While current strategies for GBM treatments are based on inducing apoptosis in GBM cells, some GBM tumors showed resistance to this type of cell death. Recent evidence indicates that pyroptosis is a novel, promising therapeutic method for overcoming tumor cells' resistance to cancer treatment. This inflammatory programmed cell death type is mediated by the cleavage of gasdermin proteins. Based on the evidence, inducing pyroptosis is negatively associated with GBM growth and development; the exact molecular mechanisms and the signaling pathways underlying pyroptosis are not fully understood. This review presents the different pathways of pyroptosis and its role in GBM growth regulating and illustrates various drugs and components that modulate pyroptosis in GBM tumors. It also investigates the regulatory roles of noncoding RNAs in pyroptosis modulation in GBM tumors, providing promising therapeutic approaches that target pyroptosis as a novel strategy for GBM treatment.\n\nID: 42381337\nTitle: Extracellular Vesicles from Mesenchymal Stem Cells Alleviate Spinal Cord Injury via the miR-486-5p/PTEN/PI3K/AKT Pathway.\nAbstract: Spinal Cord Injury (SCI) is a severe central nervous system disorder with limited effective treatments. Mesenchymal stem cell (MSC)-derived exosomes have emerged as important mediators of intercellular communication and carry microRNAs with potential neuroprotective properties. This study aimed to explore the role and underlying mechanism of human umbilical cord MSC (hUMSC)-derived exosomal miR-486-5p in experimental SCI. Exosomes were isolated from hUMSCs and characterized by transmission electron microscopy, nanoparticle tracking analysis, and exosomal marker expression. A rat SCI model and an LPS-induced PC12 cell inflammatory injury model were established. Histological injury and apoptosis were assessed by HE staining and TUNEL assay. Inflammatory cytokine levels were measured by ELISA. Cell viability, apoptosis, and gene and protein expression were evaluated using CCK-8 assay, flow cytometry, qPCR, and western blotting. A dual-luciferase reporter assay was performed to validate the interaction between miR-486-5p and PTEN. hUMSC-derived exosomes attenuated spinal cord tissue damage, reduced neuronal apoptosis, and suppressed inflammatory cytokine production in vivo and in vitro. Inhibition of exosomal miR-486-5p partially reversed these protective effects. Mechanistically, miR-486-5p directly targeted the 3'-UTR of PTEN, leading to reduced PTEN expression and enhanced phosphorylation of AKT and mTOR. These findings indicate that exosomal miR-486-5p contributes to the regulation of apoptosis- and inflammation-associated molecular events following SCI, primarily through modulation of the PTEN/AKT/mTOR signaling pathway. Given the experimental design, these results should be interpreted as mechanistic insights rather than evidence of functional recovery. hUMSC-derived exosomal miR-486-5p alleviates apoptosis and inflammation following SCI by targeting PTEN and activating the AKT/mTOR pathway. These findings provide mechanistic support for the potential application of exosome-based miRNA therapy in SCI.\n\nID: 42378634\nTitle: Lactate-Driven Restriction of Mitochondrial Permeability Transition Promotes Resistance to Chemo-Immunotherapy by Suppressing Tumor PANoptosis.\nAbstract: Intrinsic resistance limits chemo-immunotherapy efficacy in triple-negative breast cancer (TNBC). While metabolic reprogramming is linked to immune evasion, the precise mechanistic orchestration remains unclear. Here, utilizing single-cell transcriptomics and quantitative lactylome profiling, we show that elevated tumor lactate drives resistance by broadly suppressing PANoptosis. Mechanistically, under chemotherapeutic stress, the Lysine acetyltransferase 8 (KAT8) catalyzes the specific lactylation of the inner mitochondrial membrane ADP/ATP translocator 2 (ANT2)\u00a0at K92. Lactylated ANT2 recruits the phosphoglycerate mutase 5\u00a0(PGAM5) to dephosphorylate Cyclophilin D (CypD). This cascade restricts mitochondrial permeability transition pore (mPTP) opening, preserving mitochondrial homeostasis and averting immunogenic cell death. Crucially, a cell-penetrating competitive peptide targeting the KAT8-ANT2 interface effectively uncouples this metabolic lock, re-sensitizing TNBC tumors to cytotoxic stress and restoring chemo-immunotherapy efficacy in vivo. Our findings unveil a profound mechanistic link between the Warburg effect and mitochondrial homeostasis, establishing KAT8-mediated ANT2 lactylation as a targetable vulnerability to improve chemo-immunotherapy efficacy.\n\nID: 42374452\nTitle: A zinc-coordinated cascade-responsive therapeutic nanoassembly for remodeling the pathological microenvironment and restoring mitochondrial homeostasis in spinal cord injury.\nAbstract: Secondary injury after spinal cord injury (SCI) is sustained by coupled oxidative stress and inflammation, which drives neuronal apoptosis and bioenergetic failure. Here, a cascade-responsive Zn2+-centered nanoassembly (Zn-PC/PA@Gel) is constructed through stepwise coordination among Zn2+, procyanidin (PC), and polyarginine (PA) to form a core-shell architecture with a Zn2+-procyanidin core (Zn-PC) and a Zn2+-polyarginine shell (Zn-PA). In a reactive oxygen species (ROS) rich injury microenvironment, oxidation of guanidino groups in the polyarginine shell enables in situ nitric oxide (NO) release and weakens Zn2+ coordination, triggering controlled shell disassembly for early modulation of local inflammation and tissue microenvironment. The subsequent release of PC and Zn2+ provides continuous antioxidant protection. Zn2+ further restores mitochondrial quality control by regulating the STAT3-FOXO3a-SOD2 axis, thus enhancing mitochondrial autophagy, enhancing endogenous antioxidant defense, and restoring mitochondrial homeostasis and energy metabolism. In a mouse spinal cord contusion model, Zn-PC/PA@Gel mitigated inflammation and oxidative stress, alleviated the burden of mitochondrial dysfunction, protected neurons, and promoted motor recovery, resulting in a Basso Mouse Scale (BMS) score of 7.0 on day 28. Overall, these results support Zn2+ coordinated cascade therapy nanoassembly, which combines microenvironmental regulation with mitochondrial homeostatic recovery to reduce secondary injury after SCI and promote locomotor improvement.\n\nID: 42368710\nTitle: Mild photothermal therapy ameliorates neurogenic bladder after sacral spinal cord injury via multi-target effects.\nAbstract: Neurogenic bladder (NB) is a devastating complication following sacral spinal cord injury (SSCI), often leading to urinary incontinence, recurrent infections, and progressive renal dysfunction, which severely impair patients' quality of life and survival. Current therapeutic options remain largely palliative and fail to reverse the underlying neurogenic pathology. This study employed mild photothermal therapy (MPTT) to treat SSCI-induced NB in rats and systematically investigated its efficacy and mechanisms. Results showed that MPTT effectively improved bladder morphology and urodynamic parameters, with more significant effects observed in early intervention. Mechanistically, MPTT inhibited bladder fibrosis, alleviated chronic inflammation, restored the balance between cell proliferation and apoptosis, promoted functional angiogenesis, and repaired structural damage and function of bladder nerve fibers. MPTT ameliorates SSCI-NB function through multi-target effects, and its time-dependent therapeutic efficacy suggests the necessity of early and repeated interventions, providing experimental and theoretical evidence for new NB treatment strategies.\n\nID: 42349221\nTitle: Corrigendum to \"Salvigenin mitigates neuronal ferroptosis by binding to PI3K and enhancing the interaction between VCP and PI3K in the repair of spinal cord injury\" [Phytomedicine, Volume 147, 2025, 157181].\nAbstract: \n\nID: 42341847\nTitle: Edaravone attenuates ACSL4-dependent ferroptosis in spinal motor neurons following cardiac arrest in rats.\nAbstract: The contribution of acute spinal motor neuron injury following cardiac arrest (CA) remains poorly understood. This study aimed to investigate the role of ferroptosis in CA-induced spinal cord injury and to evaluate the neuroprotective effects of edaravone. Asphyxial CA was induced in rats for 5\u202fmin, followed by resuscitation. Edaravone was administered immediately after the return of spontaneous circulation (ROSC). At 24\u202fh post-ROSC, The CA group exhibited significant hindlimb motor deficits and reduced survival rates. Histological analysis revealed selective injury of choline acetyltransferase (ChAT)-positive motor neurons in the lumbar spinal cord, accompanied by mitochondrial shrinkage and membrane rupture, which are characteristic of ferroptosis. Immunofluorescence demonstrated a selective upregulation of the pro-ferroptotic enzyme acyl-CoA synthetase long-chain family member 4 (ACSL4) specifically in ChAT-positive motor neurons, whereas glutathione peroxidase 4 (GPX4) expression remained relatively preserved. Edaravone treatment significantly improved neurological outcomes and survival, attenuated lipid peroxidation (evidenced by decreased malondialdehyde and preserved glutathione levels), and effectively suppressed ACSL4 upregulation in the motor neurons. Furthermore, edaravone mitigated neuroinflammation by reducing astrogliosis and microglial activation. These findings provide the first evidence that ACSL4-mediated ferroptosis is a key driver of acute spinal motor neuron injury following CA. Edaravone exerts potent neuroprotection by targeting this pathway, suggesting its therapeutic potential for ameliorating spinal cord injury in patients with CA.\n\nID: 42337999\nTitle: Anti-HMGB1 Antibody Therapy Ameliorates Depression Following Spinal Cord Injury in Rats by Inhibiting Ferroptosis.\nAbstract: Depression following spinal cord injury (D-SCI) refers to a depressive state that occurs in an individual after a major spinal cord injury (SCI), characterized mainly by low mood and reduced interest. This study aims to investigate the regulatory role of anti-HMGB1 antibody in the depressive-like behaviour of D-SCI rats and to explore its underlying mechanisms. A depression model was established in rats 5\u2009weeks after SCI. The expression of HMGB1 and ferroptosis markers (MDA, GSH and iron ion deposition) in the hippocampus were examined in both the sham group and the D-SCI group. Subsequently, D-SCI rats were treated with an anti-HMGB1 antibody, and the depression-like behaviours of each group were assessed using open field and sucrose preference tests. Ferroptosis levels in the hippocampus, as well as the expression of ferroptosis-related proteins (ACSL4, SLC7A11 and GPX4), were also investigated. The co-localization of HMGB1 and NeuN in the rat hippocampus was detected by immunofluorescence double staining. Furthermore, at the cellular level, the effect of the anti-HMGB1 antibody on Erastin-induced ferroptosis in rat hippocampal neurons was analysed. The results indicated that compared to the sham group, the levels of HMGB1 and ferroptosis in the hippocampus of rats in the D-SCI group were significantly elevated. Administering anti-HMGB1 antibody to D-SCI rats could significantly augment their activity distance, movement speed and sucrose preference rate, while also suppressing the ferroptosis level and the expression of ferroptosis-related proteins in the hippocampus. Moreover, HMGB1 and NeuN were co-expressed in the rat hippocampus. The results from primary rat hippocampal neurons indicated that anti-HMGB1 antibody could inhibit erastin-induced ferroptosis in rat hippocampal neurons. Taken together, anti-HMGB1 antibody therapy can ameliorate depressive behaviour in D-SCI rats; the possible mechanism may involve the inhibition of ferroptosis in hippocampal neurons.\n\nID: 42332524\nTitle: Investigation of potential targets and mechanisms of naringenin in the treatment of spinal cord injury: A network pharmacology, molecular docking, and molecular dynamics simulation study.\nAbstract: Spinal cord injury (SCI) is a disease that causes significant functional impairment and high mortality, imposing a heavy economic burden on patients and society. In this in-silico study, we investigated the potential therapeutic targets and underlying mechanisms of naringenin (NAR) in SCI by integrating network pharmacology, molecular docking, and molecular dynamics (MD) simulation. The intersection of NAR and SCI targets was used to construct a protein-protein interaction network using the STRING database. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and Wiki Pathway enrichment analyses were performed using the DAVID bioinformatics resource. Finally, we used molecular docking and MD simulation to study the binding interactions between NAR and the core targets. The results show that the core targets of NAR for spinal cord injury include estrogen receptor 1, AKT serine/threonine kinase 1, B-cell lymphoma 2, PPARG, MAPK8, mechanistic target of rapamycin, protein kinase cAMP-activated catalytic subunit alpha, and HRas proto-oncogene, GTPase. These targets and associated biological processes provide multiple mechanisms supporting NAR's action. In addition, enrichment analysis indicates that the AMPK, FoxO, and PI3K-Akt-mechanistic target of rapamycin signaling pathways, autophagy, and apoptosis are the main pathways through which NAR acts in SCI. Molecular docking results show that the binding energy between NAR and key proteins ranges from -7.1 to -8.2 kcal/mol, providing a molecular basis for NAR's treatment of SCI. Molecular dynamics simulation results indicate that the AKT serine/threonine kinase 1-NAR and B-cell lymphoma 2-NAR complexes exhibit good stability. In summary, this study systematically predicts the key targets and signaling pathways through which NAR may act in SCI, providing a theoretical basis for future mechanistic and translational research. However, because the findings are based on computational analyses alone, further in vitro and in vivo validation is required.\n\nID: 42331045\nTitle: Inadvertent p75NTR signaling might cause inconsistencies in the neuroprotection offered by mesenchymal stem cells.\nAbstract: Bone marrow-derived mesenchymal stromal cells (BMSCs) have been shown to enhance regeneration and repair, even in challenging neurological conditions such as spinal cord injury (SCI). However, their clinical application for SCI remains inconsistent, likely due to variability in therapeutic outcomes. In our laboratory experiments, we observed similar inconsistencies, including instances where the presence of BMSCs compromised the survival of co-cultured neurons subjected to oxidative stress in vitro. The present study was carried out to find answers for such paradoxical effects caused by BMSCs using an in vitro model involving primary cultured neurons and BMSCs. Both neurons and BMSCs were found to upregulate brain-derived neurotrophic factor (BDNF) production under oxidative stress. To simulate BMSC-mediated release, we introduced exogenous mature BDNF (mBDNF) to stressed neurons in cultures, which unexpectedly led to apoptosis. Observations suggest the possibility of mBDNF-p75 neurotrophin receptor (p75NTR) mediated cell death signaling. Notably, administration of a p75NTR inhibitor (LM11A-31, a small molecule) partially alleviated these detrimental effects. Given the growing interest in BMSC-based therapies, these findings underscore concerns regarding the variability of their effects and the potential for unintended neurotoxicity. Addressing these inconsistencies through further studies will be critical to ensuring the safety and efficacy of BMSC applications in clinical settings. In this regard, concomitant inhibition of p75NTR using small molecules such as LM11A-31 may have potential to avoid contradictory effects of BMSC transplantations caused by unpredictable release of excess BDNF in the transplanted site.\n\nID: 42327493\nTitle: Exercise-derived exosomal miR-151-3p: An innovative anti-inflammatory and antioxidant therapeutic for spinal cord injury.\nAbstract: Exercise (Exe) training is a cornerstone of multimodal rehabilitation of patients with spinal cord injury (SCI), yet the precise mechanisms through which it exerts its therapeutic benefits remain unclear. Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy.\n\nID: 42317798\nTitle: LXR\u03b1/SCD1-Mediated Endoplasmic Reticulum-Mitochondria Crosstalk in Inhibiting Neuronal Ferroptosis after Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) causes extensive neuronal loss, in which ferroptosis is critically involved. Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma.\n\nID: 42317583\nTitle: Neural stem cell-derived extracellular vesicles drive early neuroprotective and anti-apoptotic responses in spinal cord injury organotypic slices.\nAbstract: Spinal cord injury (SCI) is a devastating neurological condition with limited regenerative capacity. Stem cell-based approaches have emerged as promising strategies due to their neuroprotective and immunomodulatory properties, largely mediated by small extracellular vesicles (sEVs) and their molecular cargo, including miRNAs. In this study, we aimed to evaluate the neuroprotective and anti-apoptotic potential of sEVs derived from SPC-01 and iMR-90 neural stem cell sources using an in vitro rat model of SCI. sEVs were isolated from SPC-01 and iMR-90 culture media and characterized by MADLS and Western blot. Spinal cord slices (SCS) were used as an in vitro SCI model with three groups: control, SCI, and SCI treated with sEVs. Injury was induced at 18-20\u202fdays in vitro, followed by immediate sEV application. After 72\u202fh, tissue samples were collected and analyzed to assess proteins associated with apoptosis, cytoskeletal integrity, and survival signaling pathways. SCI induced cytoskeletal disruption and increased apoptotic markers. sEV treatment attenuated these changes, reducing injury-associated proteins toward baseline levels. Both SPC-01- and iMR-90-derived sEVs showed neuroprotective effects. This was associated with modulation of key pathways, including decreased PTEN, increased STAT3 phosphorylation, and elevated Bcl-xL. Reduced Nogo-A and normalized RhoA levels further indicate attenuation of inhibitory signaling and improved cytoskeletal stability. Overall, sEVs promoted early neuroprotective responses and reduced pathology-associated protein expression in the SCI model. Neural stem cell-derived sEVs promote neuroprotection in vitro by modulating PTEN/STAT3 signaling, reducing apoptosis, and stabilizing cytoskeletal dynamics. Although limited to early injury responses in an in vitro model, these findings support sEVs as a promising cell-free therapeutic strategy for SCI.\n\nID: 42521977\nTitle: Regulated cell death-induced coagulation dysfunction in sepsis.\nAbstract: Regulated cell death (RCD) has emerged as a pivotal upstream mediator supported by correlative preclinical and clinical evidence in the pathogenesis of sepsis-induced coagulopathy (SIC), a life-threatening complication strongly linked to increased mortality. RCD-guided phenotyping integrates pyroptosis, NETosis, ferroptosis, necroptosis, and PANoptosis pathways to systematically redefine SIC - from molecular signatures to targeted interventions. This review comprehensively examines how RCD-derived Damage-Associated Molecular Patterns (DAMPs) mediate coagulation dysfunction, explores subtype-specific biomarkers for patient stratification, and outlines phenotype-directed combination therapies. We further investigate unresolved challenges and future developments in RCD-guided precision immunomodulation, emphasizing the transformative potential of RCD-based frameworks to advance the clinical management of SIC by bridging insights from cell death and thrombosis research.\n\nID: 42521052\nTitle: Exploring Ferroptosis: Unraveling Its Potential Role in Autistic Spectrum Disorder.\nAbstract: Autism spectrum disorder (ASD) is a diverse neurodevelopmental disorder characterized by ambiguous etiological mechanisms and the absence of recognized disease-modifying pharmacotherapies. Ferroptosis, an iron-dependent and lipid peroxidation-driven mechanism of regulated cell death, has been associated with neurodevelopment and neurodegeneration, prompting interest in its potential role in ASD. This narrative review consolidates from molecular and clinical studies, animal models, and in vitro systems to assess ferroptosis as a candidate mechanistic pathway, biomarker source, and therapeutic target in ASD. Peripheral transcriptomic analyses reveal differentially expressed ferroptosis-related genes, ferroptosis-based molecular clusters, and immune-activated subtype in children with ASD, facilitating the development of ferroptosis-derived diagnostic and scoring models with modest yet reproducible discrimination. Clinical data associate maladaptive polyunsaturated fatty acid profiles, increased lipid peroxidation products, and adverse docosahexaenoic acid/arachidonic acid ratio with autistic social impairments, aligning with ferroptosis-prone conditions. In rodent models, genetic or pharmacological modulation of DDIT4-PI3K/Akt signaling, Nrf2/GPX4/xCT antioxidant systems, and ferritinophagy mitigates ASD-like social deficits, repetitive behaviors, anxiety-like phenotypes, and liver pathology. Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways, indicating subtype-specific ferroptosis resistance. These findings suggest a complex, context-dependent role of ferroptosis and ferroptosis resistance in ASD, interacting with immune dysregulation, redox imbalance, and peripheral organ involvement. Nevertheless, longitudinal and interventional studies integrating brain, peripheral, and cellular data are required to establish causality, define meaningful ferroptosis-related signatures, and evaluate the safety and efficacy of ferroptosis-modulating interventions.\n\nID: 42520640\nTitle: Ultrasmall nanosonocatalyst induces PANoptosis to suppress ovarian cancer: From patient-derived organoids to in vivo models.\nAbstract: Ovarian cancer represents one of the most lethal gynecological malignancies, marked by a high recurrence rate and dismal prognosis. Existing targeted treatments face challenges such as limited applicability, modest effectiveness, and considerable costs, underscoring the demand for novel therapeutic alternatives. Growing research suggests that triggering a significant intracellular reactive oxygen species (ROS) surge can selectively induce oxidative destruction and death in tumor cells with compromised redox balance, while largely sparing normal cells. In this work, we designed lanthanum-doped zinc sulfide (ZnS:La) nanocrystals as an efficient sonocatalyst to augment sonodynamic treatment for ovarian cancer. Under ultrasound exposure, ZnS:La demonstrated improved charge separation and a notable boost in ROS generation, leading to substantial oxidative injury in cancer cells. Concurrently, the slow release of La3+ ions contributed to lysosomal membrane disruption, increasing cellular susceptibility to oxidative stress. These processes promoted the formation of PANoptosomes and initiated PANoptosis-a synergistic type of programmed cell death encompassing apoptosis, pyroptosis, and necroptosis. In evaluations using patient-derived organoids, subcutaneous grafts, and orthotopic ovarian tumor models, ultrasound-activated ZnS:La consistently inhibited tumor progression and spread. This study introduces a powerful sonocatalyst-based approach to engage multiple programmed cell death mechanisms, highlighting a potential new direction for ovarian cancer therapy.\n\nID: 42518995\nTitle: Neuroprotective potential of the natural polyphenol Procyanidin B2 in spinal cord injury: a comprehensive study utilizing machine learning, network pharmacology, and in vivo validation.\nAbstract: The secondary injury cascade following spinal cord injury (SCI) drives severe inflammation and tissue destruction. Although the natural polyphenol Procyanidin B2 (PCB2) has well-documented neuroprotective properties, its specific therapeutic efficacy in SCI, as well as its precise therapeutic targets and immunomodulatory mechanisms, remain unclear. We applied an integrated bioinformatics and in vivo approach. Target predictions were cross-referenced with SCI transcriptomic profiles from GEO datasets. Four machine learning algorithms were used to isolate core regulatory genes. Single-cell RNA sequencing mapped the primary target's distribution, and molecular docking estimated binding affinities. Mechanistic predictions were validated in a rat T10 spinal cord contusion model via Basso-Beattie-Bresnahan (BBB) scoring, histology, immunofluorescence, and Western blot. Network pharmacology initially yielded 59 shared targets, with functional enrichment pointing to PCB2's broad involvement in Toll-like receptor and p53 signaling, as well as tissue remodeling. This suggests its potential for multi-target anti-inflammatory and anti-apoptotic intervention. Machine learning algorithms then pinpointed Caspase-1 (CASP1) as the central regulatory node. Single-cell RNA sequencing showed that CASP1 expression surges specifically within macrophages and microglia following injury. Molecular docking supported a robust interaction (-7.2 kcal/mol) between PCB2 and the active pocket of CASP1. In our rat model, administering PCB2 notably hastened the return of bladder control and increased BBB locomotor scores. Histology confirmed that treated animals had smaller lesion volumes, better myelin integrity, and less inflammatory cell infiltration. At the molecular level, PCB2 significantly suppresses CASP1 expression, thereby blunting secondary damage. PCB2 demonstrates significant neuroprotective effects in SCI. Its mechanism primarily involves targeting CASP1 in myeloid cells, to lower its expression, thereby shifting the microenvironment toward repair, providing a translational basis for utilizing natural polyphenols like PCB2 in managing secondary spinal cord trauma and supporting overall central nervous system health.\n\nID: 42517186\nTitle: Mitochondrial Dysfunction at the Crossroads of Necroptosis: Mechanisms, Molecular Mediators, and Therapeutic Opportunities.\nAbstract: The conceptual landscape of cell death has evolved beyond the traditional dichotomy of apoptosis and necrosis to encompass diverse regulated pathways including necroptosis, autophagy, ferroptosis, and pyroptosis. Necroptosis, a caspase-independent inflammatory form of programmed cell death, has emerged as a critical driver of the pathogenesis of cardiovascular disorders, neurodegenerative diseases, and cancer. Concurrently, our understanding of mitochondrial biology has undergone a paradigm shift: mitochondria are no longer viewed merely as bioenergetic powerhouses, but as dynamic signalling hubs that orchestrate metabolic reprogramming, cellular homeostasis, and ultimate cell fate decisions. In this regard, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This review delineates the mechanistic interplay between necroptosis and mitochondrial dysfunction and systematically analyzes the key molecular mediators and pathological pathways through which mitochondrial dysregulation drives necroptotic activation. Furthermore, this review identifies actionable therapeutic targets and translational strategies for modulating necroptosis in related diseases.\n\nID: 42510529\nTitle: Metabolic Reprogramming Associated with Ferroptosis Protection by an Indole-Based Antioxidant in A\u03b2(25-35)-Treated SH-SY5Y Cells.\nAbstract: Ferroptosis has emerged as a critical mechanism linking iron dysregulation, oxidative stress, and neurodegeneration in amyloid-associated pathologies. Building on our previous work, which identified compound 20 as a promising antioxidant and neuroprotective agent, the present study investigates the molecular mechanisms underlying its protective activity against amyloid-induced ferroptosis in human neuroblastoma SH-SY5Y cells exposed to A\u03b2(25-35). Compound 20 (3-(((4-hydroxybenzyl)(methyl)amino)methyl)-1-methyl-N-(2-(piperazin-1-yl)ethyl)-1H-indole-5-carboxamide) markedly counteracted A\u03b2(25-35)-induced ferroptotic damage by restoring intracellular glutathione levels, depleting the labile iron pool, and suppressing lipid peroxidation. In parallel, the compound significantly rescued mitochondrial membrane potential and attenuated endoplasmic reticulum (ER) expansion associated with ER stress, thereby preserving cellular homeostasis under oxidative challenge. These protective effects were further corroborated by real-time PCR analysis, which revealed the modulation of key genes involved in the oxidative stress response, endoplasmic reticulum stress, and inflammatory pathways. To gain a systems-level insight into these mechanisms, untargeted 1H-NMR metabolomic profiling was performed. This analysis confirmed the activation of antioxidant pathways and disclosed a significant modulation of energy metabolism and GABA-related pathways, both of which are closely linked to redox balance and neuronal resilience. Overall, these findings demonstrate that compound 20 drives metabolic reprogramming that orchestrates its multifactorial protective effect against A\u03b2(25-35)-induced ferroptosis by coordinating antioxidant defense, iron homeostasis, and ER stress mitigation.\n\nID: 42508713\nTitle: PNU-120596, an \u03b17 nicotinic acetylcholine receptor positive allosteric modulator, attenuates microglial activation and protects dopaminergic neurons from inflammatory injury independently of canonical \u03b17 nicotinic acetylcholine receptor signaling.\nAbstract: Neuroinflammation plays an important role in the pathogenesis of Parkinson's disease, with microglial overactivation contributing to dopaminergic neuronal loss. Recent studies indicate that \u03b17 nicotinic acetylcholine (nACh) receptors modulate the inflammatory responses of immune cells. Although \u03b17 nACh receptors are expressed in microglia, their precise role in microglial activation is unclear. In this study, we determined whether \u03b17 nACh receptor stimulation could protect dopaminergic neurons from inflammation-induced injury. Nicotine and PNU-120596, an \u03b17 nACh receptor positive allosteric modulator, significantly attenuated dopaminergic neurotoxicity in primary mesencephalic cultures treated with inflammatory stimuli. However, only PNU-120596 inhibited microglial activation, and this effect was not reversed following treatment with an \u03b17 nACh receptor antagonist, suggesting a mechanism distinct from the classical \u03b17 nACh receptor-mediated signaling. PNU-120596 suppressed inducible nitric oxide synthase (iNOS) expression and signal transducer and activator of transcription 1 (STAT1) phosphorylation, but did not alter the nuclear translocation of nuclear factor-\u03baB. Moreover, in BV2 cells, which lack detectable full-length \u03b17 nACh receptor mRNA, PNU-120596 also suppressed iNOS expression and STAT1 phosphorylation. These results suggest that PNU-120596 exerts anti-inflammatory and neuroprotective effects independently of canonical pathways that are not dependent on classical \u03b17 nACh receptor-mediated signaling.\n\nID: 42506907\nTitle: NAD+ depletion links metabolic stress to drive innate immune priming and selectively control PANoptosis.\nAbstract: The innate immune system can detect infection, tissue damage, and other homeostatic disruptions to initiate an immune response, drive inflammation, and promote programmed cell death. While these responses can be beneficial in host defense, aberrant activation of inflammatory, lytic cell death pathways can be pathogenic. Emerging evidence suggests that cellular metabolic disruption can promote inflammatory cell death, but the mechanistic connections between these processes are not well understood, limiting our ability to identify regulatory nodes that can be therapeutically targeted. Here, we found that intracellular levels of the metabolic cofactor nicotinamide adenine dinucleotide (NAD+) were depleted in response to cell death triggers that drive pyroptosis, necroptosis, PANoptosis, and ferroptosis. However, restoring NAD+ inhibited PANoptosis but not the other forms of cell death. Mechanistically, NAD+ restoration reduced the expression of PANoptotic sensors or regulators, including the transcription factor IRF1, a critical factor for innate immune sensor priming in PANoptosis. Our findings thereby suggest that NAD+ depletion is an early cell death signaling event and that restoring NAD+ levels specifically blocks PANoptosis by suppressing priming. Hence, targeting NAD+ metabolism represents a potential therapeutic strategy for infectious and inflammatory diseases associated with dysregulated PANoptosis.\n\nID: 42505382\nTitle: Lipid Droplets as Metabolic-Epigenetic Signaling Hubs: Interplay Between Phase Separation, Cellular Adaptation, and Disease.\nAbstract: Lipid droplets (LDs) were long thought to be passive organelles merely for neutral lipid storage. Mounting evidence redefines LDs as dynamic metabolic signaling hubs orchestrating cellular stress adaptation, with multifaceted roles in organelle crosstalk, metabolic reprogramming, redox balance and immune signaling. LD function is tightly intertwined with liquid-liquid phase separation (LLPS) and epigenetic remodeling, bridging cellular metabolism to gene expression and cell fate control. LD biogenesis relies on ER lipid structures, phase-separated protein assemblies and lipid regulatory proteins. Via contacts with multiple organelles, LDs regulate lipid catabolism, ferroptosis, inflammation and chromatin accessibility, while their metabolites directly reshape epigenetic modifications and transcription. LLPS-driven biomolecular condensates further coordinate LD-linked metabolic and stress signaling. Dysregulated LD remodeling mediates metabolic flexibility, immune escape and drug resistance in obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), neurodegeneration, viral infection and cancer. This review summarizes progress in LD biogenesis and metabolism, dissects mechanistic crosstalk between LDs, LLPS and epigenetic control, and outlines LD-driven pathogenic reprogramming across human disorders. We also discuss therapeutic approaches targeting LD and LLPS pathways. Despite promising translational prospects, unresolved mechanistic and clinical hurdles persist. Further research on LD biology will reshape our framework linking metabolism, chromatin regulation and stress adaptation.\n\nID: 42501927\nTitle: Programmed cell death in autoimmune diseases.\nAbstract: Autoimmune diseases (AIDs) are chronic inflammatory disorders in which loss of self-tolerance intersects with tissue stress and damage. Increasing evidence indicates that regulated cell death (RCD) can act as an upstream amplifier in selected autoimmune settings, while in other settings it may mainly report downstream collateral injury caused by cytotoxic lymphocytes, immune complexes, complement activation, or tissue hypoxia. Accordingly, this review distinguishes causal death execution from associative pathway signatures and highlights the types of longitudinal, cell-type-resolved, and perturbational evidence needed to make that distinction. We summarize how apoptosis, necroptosis, pyroptosis, and ferroptosis operate as an interlocking network in autoimmune microenvironments, frequently co-existing as context-dependent mixed-death states driven by shared triggers such as cytokines, PRR ligands, and oxidative stress, and governed by decision hubs including RIPK1 and caspase-8. We highlight integrated concepts such as PANoptosis to explain pathway convergence and compensatory switching into parallel lytic branches when a single node is constrained. The review further connects mechanistic insights to translational priorities, emphasizing biomarker strategies that report pathway engagement, targeted modulation of executors or upstream sensing and cytokine circuits, and lesion-localized delivery approaches to improve the therapeutic window. Finally, we outline key gaps that must be addressed to enable precision interventions, including spatial and cell-type resolved validation of death programs, longitudinal profiling across flare-remission trajectories, and harmonized composite panels capable of capturing mixed-death dynamics in heterogeneous AIDs.\n\nID: 42501804\nTitle: Sequential delivery of STING inhibitor and rapamycin by a Sr-Zn mesoporous bioactive glass platform for spinal cord injury repair.\nAbstract: Spinal cord injury (SCI) leads to permanent neurological deficits, primarily due to immune dysregulation following trauma. Current biomaterial-based interventions often fail to address the dual need for acute inflammation control and long-term immune tolerance. Herein, we present a multifunctional Sr-Zn mesoporous bioactive glass (MBG) system that enables spatiotemporal immunoreprogramming. Rapamycin (Ra) is first loaded into MBG pores to induce Treg differentiation via mTOR inhibition. STING inhibitor H-151 is then adsorbed onto a polydopamine (PDA) coating for early suppression of cGAS-STING signaling. Finally, a CCL22-mimetic peptide is grafted for CCR4-mediated Treg recruitment. Meanwhile, sustained Sr2+/Zn2+ release provides bioactive ionic cues that support immune remodeling and neural repair. This sequential design first polarizes microglia/macrophages toward an anti-inflammatory M2 phenotype and then enriches Tregs to sustain an immunosuppressive niche, while concurrently facilitating neuroregenerative remodeling. In vitro, the system regulates STING and mTOR pathways, induces Treg generation, and enhances neural stem cell differentiation and neuronal outgrowth. In a mouse SCI model, the injectable MBG-hydrogel hybrid reduces lesion volume, promotes remyelination, axonal regrowth, and motor function. Treg depletion or CCR4 blockade abrogates therapeutic benefits, confirming the role of adaptive immunity. This study offers a dual-arm immunoengineering strategy that couples innate suppression and adaptive tolerance, opening new avenues for CNS regeneration.\n\nID: 42500791\nTitle: Association of sTREM2 and YKL-40 With Alzheimer's Disease Progression: A Systematic Review.\nAbstract: Neuroinflammation is recognized as a core feature of Alzheimer's disease (AD). Soluble triggering receptor expressed on myeloid cells 2 (sTREM2) and chitinase-3-like protein 1 (YKL-40) are fluid biomarkers of microglial and astrocytic reactivity associated with AD progression. However, their coupling to amyloid and tau pathology, stage-specific roles, and prognostic utility remain unclear. This systematic review synthesized evidence from 2021 to 2025 on associations of sTREM2 and YKL-40 with AD progression. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. PubMed/Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Institute of Electrical and Electronics Engineers (IEEE) Xplore, and Web of Science were searched (Jan 2021-Dec 2025), with citation searching. Duplicates were removed using EndNote X21 (Clarivate, London, UK). Two independent reviewers screened records using the Population, Intervention, Comparison, Outcomes, and Study Design (PICOS) criteria, with disagreements resolved by a third reviewer. Original human studies measuring sTREM2 and/or YKL-40 across the AD spectrum were included. Methodological quality was assessed using the Newcastle-Ottawa Scale (NOS). Due to heterogeneity in study design and outcomes, a narrative synthesis was performed. Thirteen studies were included: seven on sTREM2, five on YKL-40, and one on both. Six were low risk of bias, and seven were moderate. Cerebrospinal fluid (CSF) sTREM2 showed a biphasic pattern across disease stages, with early potential neuroprotective associations and later correlation with cortical atrophy and cognitive decline. A sex-APOE \u03b54 interaction was observed, with higher levels in female carriers. YKL-40 showed weak amyloid associations but strong coupling with tau pathology and neurodegeneration, influenced by vascular risk factors. Plasma YKL-40 predicted incident dementia and cognitive decline, and serum YKL-40 differentiated early dementia from controls with good diagnostic performance. sTREM2 and YKL-40 represent biologically distinct but complementary neuroinflammatory pathways in AD. sTREM2 reflects a stage-dependent microglial response, while YKL-40 reflects tau-associated astrocytic activation modulated by vascular factors. Longitudinal studies with concurrent biomarker assessment are needed to clarify their combined prognostic value.\n\nID: 42498720\nTitle: PLIN2-PGAM5-regulated lipid droplet-mitochondria contacts drive microglial neuroinflammation after spinal cord injury via fatty acid metabolic reprogramming.\nAbstract: Persistent neuroinflammation is a hallmark of central nervous system (CNS) injury, driving neuronal loss and functional deficits. While microglial lipid metabolic reprogramming, particularly lipid droplet accumulation, has been implicated in chronic inflammation, the underlying mechanisms remain poorly understood. Using single-cell transcriptomics, we identified a previously defined lipid droplet-accumulating microglia (LDAM) subpopulation in spinal cord injury (SCI), characterized by elevated PLIN2 expression. Genetic deletion of Plin2 markedly reduced lipid droplet burden, attenuated neuroinflammation, and promoted neuronal survival and functional recovery in vivo. Mechanistically, PLIN2 interacts with the mitochondrial outer membrane protein PGAM5 to regulate lipid droplet-mitochondria contacts. This interaction inverts canonical metabolic flux by redirecting fatty acids from mitochondria back to lipid droplets, thereby suppressing \u03b2-oxidation and inducing mitochondrial dysfunction, which subsequently triggers STING-dependent inflammation. Notably, the PLIN2 220-392 domain is essential for PGAM5 binding and contact formation; disrupting this interaction attenuates STING signaling and enhances neuroprotection and functional recovery in vivo. Our findings identify the PLIN2-PGAM5 as a critical metabolic-immune pathway and suggest that targeting organelle-contact-mediated metabolic reprogramming represents a potential therapeutic strategy for CNS injury.\n\nID: 42497212\nTitle: Cell-type-specific m1A dynamics are associated with microglial phenotypic transformation and neuronal metabolic adaptation during spinal cord injury.\nAbstract: m1A (N1-methyladenosine) is an important epigenetic mechanism that regulates the onset and progression of many diseases, including spinal cord injury (SCI). To investigate the overall changes in m1A levels following SCI, we analyzed transcriptomic sequencing data from SCI samples and assigned m1A scores based on the levels of m1A regulatory factors. In this study, the m1A score is an inferred proxy calculated from the expression of m1A regulator genes (writers/erasers/readers). It does not directly measure RNA m1A modification levels. Our results show that the m1A score increased within the first day after SCI and then decreased, falling below baseline by day 3 and day 7. Further analysis revealed that microglia and neurons are the two cell types with the most significant changes in the m1A score. In microglia, m1A score decreased at all time points, whereas in neurons, m1A score increased at all time points. Additionally, through pseudotime analysis and function enrichment analysis, the m1A score may be associated with the phenotypic transition of microglia and neuronal energy metabolism, and this was further validated by conducting studies both in vivo and in vitro. In a word, our study unveils the characteristic changes of m1A at both the bulk and single-cell levels following SCI, and suggests potential links to neuronal function and supports the rationale for further studies exploring m1A-related regulators as therapeutic targets in SCI.\n\nID: 42496936\nTitle: Neurotoxic effects of dietary glutamate in glaucoma and potential nutritional and pharmacological therapies: a scoping review.\nAbstract: To synthesize the available evidence on the relationship between dietary glutamate or glutamatergic metabolism and glaucomatous neurodegeneration, with emphasis on biomarkers, retinal injury mechanisms, and nutritional, antioxidant, or pharmacological strategies with neuroprotective potential. This study was conducted as a systematic and bibliometric literature review following the PRISMA 2020 logic of identification, screening, eligibility, and inclusion. Searches were performed in Web of Science, Scopus, and PubMed for studies published in English between 2020 and 2025. The search strategy combined terms related to glaucoma or ocular neurodegeneration, the glutamatergic axis, and biomarkers, mechanisms, or interventions. After screening and full-text assessment, 39 studies were included in the systematic synthesis. Due to methodological heterogeneity, the evidence was synthesized narratively and comparatively, without meta-analysis. The included studies were organized into six thematic clusters: metabolomic, transcriptomic, and diagnostic biomarkers; pharmacological and neuroprotective interventions; nutritional, antioxidant, and natural-compound neuroprotection; oxidative stress, mitochondrial dysfunction, and regulated cell death; neuroinflammation and glia-mediated retinal injury; and glutamatergic excitotoxicity and neurotransmitter imbalance. The evidence indicates that glutamate-related mechanisms in glaucoma are mainly associated with endogenous glutamatergic metabolism, excitotoxicity, impaired glutamate clearance, glutamate-glutamine homeostasis, oxidative and nitrosative stress, mitochondrial dysfunction, ferroptosis, neuroinflammation, and retinal ganglion cell vulnerability. None of the 39 included studies directly evaluated dietary glutamate or monosodium glutamate as the main exposure. The available evidence does not support a direct conclusion that dietary glutamate or MSG intake contributes to glaucoma onset or progression. Instead, current findings mainly support an indirect mechanistic relationship between endogenous glutamatergic dysregulation and glaucomatous neurodegeneration. Pharmacological, antioxidant, metabolic, and natural-compound strategies show neuroprotective potential, particularly in experimental models, but clinical and translational studies are still needed to clarify the role of dietary exposure, glutamate-glutamine metabolism, and targeted neuroprotective interventions in glaucoma.\n\nID: 42494410\nTitle: Immuno-engineered conductive hydrogels: Bridging neural signaling and microenvironmental remodeling for neural repair.\nAbstract: Nervous system injuries and diseases present formidable regenerative challenges, largely due to hostile inflammatory microenvironments that impede endogenous repair mechanisms. Conductive nanocomposite hydrogels have emerged as a transformative class of immuno-engineered biomaterials designed to actively overcome these barriers. Beyond providing electroactive scaffolds to restore neural signaling, these advanced platforms integrate functional nanomaterials (e.g., carbon-based, MXene, and conductive polymers) within biocompatible polymer networks to facilitate targeted immunomodulation. Their core scientific significance lies in their synergistic capacity to simultaneously scavenge pathological reactive oxygen species (ROS) and steer macrophage polarization towards a pro-regenerative phenotype, thereby reprogramming the inhibitory injury niche into a permissive, pro-healing milieu. This review systematically elucidates the design principles spanning crosslinking strategies to nanomaterial selection that underpin these dual functions. We critically summarize recent breakthroughs in applying these multifunctional hydrogels to treat spinal cord injury, traumatic brain injury, stroke, and peripheral nerve defects, where they demonstrate enhanced functional recovery. By bridging the fields of conductive biomaterials and immunomodulation, this work not only surveys the state-of-the-art but also provides a unified framework for developing next-generation therapeutic platforms that couple bioelectronic cues with precise immune modulation, offering a novel paradigm for neural regeneration medicine.\n\nID: 42491529\nTitle: Metal-dependent regulated cell death: Molecular architecture and translational frontiers.\nAbstract: Intracellular metal dyshomeostasis has emerged as a key regulator of specialized regulated cell death (RCD) programs, challenging classical views that regard necrosis as entirely accidental. This review systematically delineates the molecular architecture and translational trajectories underlying metal-dependent RCD, including iron-driven ferroptosis, copper-mediated cuproptosis, and additional emerging modalities such as calcicoptosis, necrosis by sodium overload (NECSO), and the newly designated zincoptosis, mnoptosis, and coptosis. We examined distinct execution mechanisms, ranging from membrane lipid peroxidation and lipoylation-targeted proteotoxic stress to organelle-specific bioenergetic failure, which arise following disruption of compartmentalized metal-buffering networks. To bridge the persistent knowledge gap between foundational metallobiology and clinical application, we evaluated a bidirectional therapeutic framework: exploiting synthetic lethality and metabolic gating via clinical inducers (e.g., sorafenib, elesclomol) to selectively eliminate therapy-resistant malignancies while deploying targeted pathway inhibitors and systemic agonists (e.g., dipyridamole, omaveloxolone) to limit pathological tissue degeneration in ischemic and neurodegenerative disorders. Recognizing that off-target multiorgan toxicity and complex in vivo crosstalk among interconnected death pathways (e.g., disulfidptosis and PANoptosis) represent major translational challenges, we assessed advanced materials-science strategies designed to overcome these barriers. Specifically, we highlighted the integration of single-atom catalysts, stimuli-responsive nanomedicines, and biomimetic carriers engineered to spatiotemporally confine catalytic oxidative flux. Finally, we examined the systemic immunological consequences of targeted metal dysregulation, detailing how metal-induced immunogenic cell death and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway hyperactivation reshape immunosuppressive microenvironments and modulate sterile inflammation, thereby enhancing responsiveness to immune checkpoint blockade, providing a definitive molecular blueprint for next-generation precision therapeutics.\n\nID: 42490372\nTitle: Conformational diversity and interaction signatures of NADH across protein families.\nAbstract: Nicotinamide adenine dinucleotide (NADH) is a ubiquitous redox cofactor that participates in a wide range of enzymatic and regulatory processes. These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors.\n\nID: 42488529\nTitle: Targeting Interleukin-6 Signaling with Reactive-Oxygen-Species-Responsive Hydrogel to Promote Regeneration after Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) triggers an excessive inflammatory response, characterized by the up-regulation of various inflammatory factors that impede neural regeneration and functional recovery. Interleukin-6 (IL-6) is an early and critical inflammatory mediator observed in lesions post-SCI. Antagonizing the signaling pathway presents a promising strategy to mitigate early inflammation and secondary injury after trauma. Here, we identified specific activation of the IL-6 receptor in neurons and microglia in lesions, indicating their responsiveness to early up-regulated IL-6 signaling within the microenvironment. In\u00a0vitro, neutralizing IL-6 signaling in microglia effectively alleviated their inhibitory effects on neuronal axon growth in conditioned media. Building on this, we developed a reactive-oxygen-species-responsive hydrogel for the sustained local delivery of tocilizumab, an IL-6 receptor antagonist, and implanted it in a complete transection SCI model. In\u00a0vivo, sustained IL-6 receptor blockade effectively reduced early inflammatory cell infiltration, modulated microglial polarization toward an anti-inflammatory phenotype, and fostered neuronal regeneration within the lesion. Importantly, this therapeutic intervention promoted long-term hind limb functional recovery in SCI mice. This study underscores the therapeutic potential of precisely targeting early inflammatory cytokine signaling pathways, particularly IL-6, to improve outcomes after SCI.\n\nID: 42484540\nTitle: Whole-Body Vibration After Compressive Spinal Cord-Injury in Rats Restores Dorsal Horn Synaptic Relations and Alleviates Pain-Associated Behavior.\nAbstract: Spinal cord injury (SCI) induces neuronal loss and demyelination, leading to maladaptive neuronal circuits that drive persistent central neuropathic pain (PCNP). While pharmacological, psychological, and physiotherapeutic approaches have been applied, including whole-body vibration (WBV), synaptic-level mechanisms of WBV remain largely unexplored. Here, we assessed the post-SCI pain-associated behavior index (PAB, based on established behavioral criteria) and compared synapse counts (SYN+, VGLUT1+, ChAT+, VGAT+), CGRP+- and SER+-structures, as well as astrocytic and microglial populations in the lumbar dorsal horn following thoracic SCI in WBV-treated and untreated rats. Animals received WBV from postoperative week 3 to 12, and outcomes were compared with non-treated controls. PAB was consistently reduced in WBV-treated animals. STED-microscopy quantification showed that WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals, as well as the number of SER\u2009+\u2009fibers. Conversely, WBV reduced CGRP\u2009+\u2009structures in the dorsal horn, decreased the density of CGRP\u2009+\u2009perisomatic and axo-axonic synapses, and lowered astrocytic and microglial populations. Our data indicate that the WBV-induced frequent (15-30\u2005Hz) muscle contractions and proprioceptive impulses contribute to spasticity modulation (via VGAT-related mechanisms) and attenuation of post-SCI hyperalgesia (CGRP-associated). Together with the reduced astro- and microglia amounts, the described synaptic alterations are considered essential prerequisites for better motor recovery. These findings provide preclinical evidence for the functional benefits of WBV in an animal SCI model and warrant further investigations to determine mechanisms underpinning this non-invasive, low-cost and easily applicable rehabilitation approach.\n\nID: 42481642\nTitle: D-dopachrome tautomerase promotes astrocytic cholesterol 25-hydroxylase expression through the ERK/NF-\u03baB pathway following rat spinal cord injury.\nAbstract: Astrocytes act as crucial cellular centres of cholesterol synthesis and metabolism and help maintain homeostasis in the healthy CNS. Spinal cord injury (SCI) results in abnormalities in astrocytic cholesterol metabolism and excessive oxysterol accumulation, contributing to the activation of inflammation. However, the relevant regulatory mechanism involved in aberrant cholesterol metabolism by astrocytes has not been fully elucidated. In the present study, we demonstrated that SCI-induced D-DT protein levels increased synchronously with CH25H expression. Administration of the D-DT inhibitor 4-CPPC markedly decreased CH25H expression in astrocytes following SCI. D-DT facilitates CH25H production in astrocytes by activating the intracellular ERK/NF-\u03baB pathway through binding to the CD74 receptor. Conditioned culture medium from astrocytes following the knockdown of astrocyte CH25H expression by siRNA reduced microglial migration. The inhibition of D-DT or CH25H activity reduces microglia/macrophage accumulation at the lesion site and improves motor functional recovery following SCI. Our results reveal a novel function of D-DT-mediated astrocytic CH25H activation, which modulates pathological microenvironments through the activation of inflammation. These data may provide a potential therapeutic strategy for CNS inflammation-associated diseases.\n\nID: 42481419\nTitle: Isoform-paralog specificity and tissue-dependent vulnerabilities in neurological disorders.\nAbstract: A long-standing observation in studies of neurological disorders is that broadly expressed disease genes can cause dysfunctions that are limited to certain brain regions or cell types. In this issue of Genes & Development, Lee et al. (doi:10.1101/gad.353596.125) address the mystery of this selective vulnerability by studying ATXN1-CIC interactions implicated in spinocerebellar ataxia type 1. They provide compelling evidence that specific ATXN1 paralogs preferentially interact with specific CIC isoforms tissue-dependently. Whereas ATXN1-CIC-L complexes regulate hippocampal gene expression and learning, ATXN1L-CIC-S complexes regulate lung alveolarization, postnatal survival, and hydrocephalus risk. This work thus demonstrates the potential contribution of isoform-paralog specificity to tissue-specific vulnerabilities in neurological disorders.\n\nID: 42480533\nTitle: Dual-function PROTAC suppresses ferroptosis and restores neuronal function via brain-targeted delivery.\nAbstract: Targeted protein degradation (TPD) via proteolysis-targeting chimeras (PROTACs) offers a promising strategy for modulating disease-associated proteins, yet effective brain-preferred protein degradation remains challenging. Herein, we report a dual-function PROTAC, dACSL4, and its nose-to-brain delivery for brain-preferred protein degradation and therapeutic suppression of ferroptosis in neurodegeneration. dACSL4 selectively degrades acyl-CoA synthetase long-chain family member 4 (ACSL4) while concurrently activating peroxisome proliferator-activated receptor \u03b3 (PPAR\u03b3), thereby coordinating lipid metabolism and oxidative stress to suppress neuronal ferroptosis. dACSL4 achieved up to 30-fold greater protection against neuronal ferroptosis compared to conventional ferroptosis inhibitors. Intranasal delivery of dACSL4 using biodegradable lipid nanoparticles (BAmP-TK12) enabled brain-preferred ACSL4 degradation and PPAR\u03b3 activation, reducing lipid peroxidation and preserving dopaminergic neurons in a Parkinson's disease model, ultimately improving motor function. Our findings establish a modular strategy for brain-preferred protein degradation and highlight the therapeutic potential of dual-function degraders for ferroptosis suppression in neurodegenerative diseases.\n\nID: 42476928\nTitle: Alzheimer's Disease: A Review of Molecular Mechanisms and Interventions Targeting A\u03b2-Binding Receptors.\nAbstract: In the pathogenesis of Alzheimer's disease (AD), the aggregation of A\u03b2 peptides into A\u03b2 oligomers (A\u03b2Os) plays a critical neurotoxic role. By binding to various cell membrane receptors, A\u03b2Os can trigger abnormal intracellular signaling transduction, leading to neuronal damage. This article systematically summarizes the interaction mechanisms of nearly ten A\u03b2O-binding receptors and focuses on reviewing recent therapeutic strategies aimed at neuroprotection through interventions in A\u03b2O-receptor interactions or by blocking/modulating relevant receptor signaling pathways. The discussed content provides a molecular theoretical foundation and research perspectives for the rational design of anti-AD drugs targeting A\u03b2O receptors.\n\nID: 42476817\nTitle: Functional divergence of Capicua isoforms explains differential tissue vulnerability in neurological disease.\nAbstract: Many neurological diseases impact specific brain regions despite widespread expression of the disease-related protein. Spinocerebellar ataxia type 1 (SCA1) primarily affects the cerebellum, though Ataxin-1 (ATXN1) is widely expressed. We previously showed that intensified interaction between mutant ATXN1 and Capicua (CIC) drives SCA1 pathogenesis in the cerebellum, whereas ATXN1 loss augments amyloid \u03b2 production in the hippocampus and cortex. CIC, however, forms a complex with ATXN1 and its paralog, Ataxin-1-like (ATXN1L), yet knockout of either yields completely different phenotypes. To determine whether this could be due to CIC having two isoforms, we generated mice bearing either the long (CIC-L) or short (CIC-S) isoform. Loss of CIC-L led to cognitive deficits, whereas loss of CIC-S caused early postnatal lethality, phenocopying ATXN1 and ATXN1L knockout mice, respectively. Furthermore, CIC-L preferentially interacts with ATXN1, and CIC-S with ATXN1L. Our data underscore the importance of isoform-paralog interplay in studying regional vulnerability in neurodegenerative diseases.\n\nID: 42474555\nTitle: Neural network-enhanced investigation of ferroptosis and druggability in early-onset alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder which is multifactorial in nature. Some of its characteristics are slow cognitive decline, memory problems and behavioral changes. AD patient brains show a progressive synaptic toxicity, autophagy, neuroinflammation, excess generation of reactive oxygen species (ROS), neuronal death and oxidative stress, which occurs due to disrupted metal homeostasis along with tau and amyloid-\u03b2 protein deposition. Notably, lipid peroxidation, iron buildup and elevated oxidative stress in AD brains suggest a possible molecular\u00a0connection between ferroptosis and AD neurodegeneration. This study explores the genetic and bioinformatics perspective on the relationship between ferroptosis and AD aiming to identify potential therapeutic potential biomarkers using Neural network (NN) and Machine learning models. Six ferroptosis related genes were found to be differentially expressed in AD. Further machine learning analysis shortlisted four key biomarker genes. An NN-based diagnostic prediction model was developed and validated using AUC-ROC anaysis, which gave high diagnostic values (AUC- 0.92) in the analysis. The findings highlight a strong correlation between ferroptosis and altered metabolic functions in AD. miRNA-gene interaction analysis revealed that two biomarker genes, CYBB and ACSL4 can be regulated by several regulatory miRNAs i.e., hsa-miR-146-5p, hsa-miR-106b-5p, hsa-miR-223-3p, hsa-miR-155-5p, hsa-miR-34a-5p, hsa-miR-125b-5p and hsa-miR-27a-3p suggesting their potential as early diagnostic potential biomarkers. Immune microenvironment analysis revealed strong neuroinflammatory responses in AD with increased infiltration of macrophages (M0, M1 and M2), monocytes and multiple T cell subsets. This heightened immune activity may be driven by ferroptosis-induced oxidative stress contributing to neuronal death. Furthermore, druggability of these targets was evaluated and several drugs were identified that may be potentially repurposed for therapeutic intervention in AD pathogenesis. This study presents a diagnostic predictive model integrating gene expression, miRNA regulation and immune infiltration analysis, offering a novel perspective on early AD detection. The identified ferroptosis-related potential biomarkers and regulatory miRNAs could serve as valuable tools for clinical diagnosis and targeted therapeutic intervention, advancing personalized treatment strategies for Alzheimer's disease.\n\nID: 42468674\nTitle: Allicin alleviates myocardial PANoptosis during ischemia-reperfusion by inhibiting TLR4 activation.\nAbstract: PANoptosis is a newly identified form of programmed cell death characterized by necroptosis, pyroptosis, and apoptosis. However, the mechanism of myocardial PANoptosis in myocardial ischemia-reperfusion (MI/R) remains unclear. Allicin is a promising drug for MI/R treatment, and the targets for myocardial PANoptosis remain to be explored. This study aims to clarify the mechanism of myocardial PANoptosis during MI/R and therapeutic targets of allicin. Sprague-Dawley rats were used to establish MI/R models. Allicin (3.6\u202fmg/kg) was injected via the tail vein 5\u202fmin before reperfusion. Myocardial damage (cardiac function, structure, cTnT, CK-MB and apoptosis), PANoptosome components (RIPK1/3, caspase-8, ASC and NLRP3), PANoptosis indicators (MLKL, GSDMD, IL-1\u03b2/18 and caspase-3) were assessed to evaluate the cardioprotective effects of allicin. Subsequently, the potential signaling pathway related to PANoptosis and therapeutic targets of allicin were screened through transcriptomic analysis, and TLR4 signaling was selected for verification. Then, H9C2 cells were used to establish an oxygen-glucose deprivation/reperfusion (OGD/R) model. The TLR4 inhibitor TAK-242, agonist RS09, and allicin were used to clarify the pathological role of TLR4 in myocardial PANoptosis and the therapeutic target of allicin by measuring the indicators of myocardial damage, PANoptosis and TLR4 expression. In vivo experiments revealed that allicin alleviated MI/R injury and reduced both myocardial PANoptosome components and PANoptosis. Based on transcriptomic analysis and published studies, the TLR4 signaling pathway was selected to verify the pathological role in PANoptosis and the therapeutic effects of allicin. In vitro experiments demonstrated that TLR4 activation further aggravated OGD/R-induced PANoptosis and increased TLR4 expression. Conversely, both allicin and the TLR4 inhibitor suppressed myocardial PANoptosis and TLR4 expression. Allicin can reduce myocardial PANoptosis and ameliorate MI/R injury by inhibiting TLR4 activation. These findings provide a new target and strategy for the treatment of MI/R injury.\n\nID: 42468577\nTitle: Targeting neuroinflammation and neurodegeneration in Parkinson's disease: Emerging natural and synthetic therapeutic strategies.\nAbstract: Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder worldwide. It is associated with the ongoing degeneration of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies that contain \u03b1-synuclein. These pathological changes lead to abnormalities of motor symptoms (tremor, rigidity, bradykinesia) and non-motor symptoms (cognitive decline, sleep abnormalities, psychiatric abnormalities). The pathogenesis of PD is complex and multifactorial, involving interconnected mechanisms such as oxidative stress, mitochondrial dysfunction, neuroinflammation, impaired autophagy, ferroptosis, and genetic factors. To develop effective therapeutic interventions, these pathways need to be understood. Current treatments, such as levodopa and deep-brain stimulation (DBS), are symptom-based and do not break disease progression. Thus, considerable research efforts have been geared towards finding disease-modifying therapeutic strategies. Natural bioactive compounds, gene-based therapies, stem cell-based therapies, and nanotechnology-assisted drug delivery systems are promising alternatives as suggested by recent advances. Antioxidant compounds like curcumin, resveratrol, and epigallocatechin gallate (EGCG) show promising antioxidant and neuroprotective effects, and nanomedicine provides boosted delivery to the brain and targeted drug distribution. In future clinical applications, these new strategies could help to more effectively and permanently manage PD.\n\nID: 42461929\nTitle: Long-Acting RXR Agonism Preserves Retinal Function and Modulates Inflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss and is associated with reduced nuclear retinoid X receptor (RXR) activity. Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy.\n\nID: 42458498\nTitle: TREM2 in neurodegenerative diseases and acute neurological injuries: mechanisms to targeted therapies.\nAbstract: Triggering receptor expressed on myeloid cells 2 (TREM2) is a critical myeloid receptor expressed on the surface of central nervous system microglia, capable of integrating signals from lipids, damage-associated molecular patterns, and abnormal protein aggregates to regulate phagocytosis, metabolic adaptation, inflammatory remodeling, and pathology-associated responses. Accumulating evidence indicates that TREM2 is neither uniformly protective nor uniformly pathogenic; rather, its biological effects are highly context-dependent, governed collectively by disease stage, pathological substrates, cellular compartments, and the local microenvironment. By coupling with TYROBP/DAP12 or DAP10, TREM2 actively drives the state remodeling of pathology-associated microglia. It profoundly influences the onset and progression of neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS), as well as acute central nervous system injuries, including ischemic stroke, spinal cord injury (SCI), and traumatic brain injury (TBI). Concurrently, soluble TREM2 (sTREM2) holds significant potential not only as a biomarker but also as a context-dependent effector molecule actively participating in pathological regulation. This review synthesizes current advancements by focusing on four core themes: the structural and signaling logic of the TREM2 axis; its regulation of disease-associated microglia (DAM) remodeling; the cross-disease significance of sTREM2; and the mechanistic basis for the divergent outcomes observed with TREM2-targeted therapies across different experimental models and disease stages. The objective is to elucidate the context-dependent roles of TREM2 by analyzing consensus mechanisms, sources of discrepancy, and translational implications, thereby providing a theoretical framework and strategic direction for more precise TREM2-targeted interventions.\n\nID: 42456380\nTitle: Therapeutic potential of PANoptosis in calcium oxalate crystal-induced kidney injury: An integrated view of cell death pathways.\nAbstract: Calcium oxalate (CaOx) stones account for more than 80% of kidney stones and are one of the most common diseases in the urinary system. The core pathological event of CaOx crystals is the damage of renal tubular epithelial cells (RTECs). Recent studies have shown that CaOx crystals can induce a variety of programmed cell death (PCD) pathways, such as apoptosis, pyroptosis, necroptosis, and ferroptosis, in RTECs at the same time, and there are complex compensations and crosstalk between these death pathways, resulting in the limited efficacy of a single targeting strategy. Therefore, exploring the mechanisms that can integrate the regulation of multiple cell death pathways has become an important direction in this field. PANoptosis is an inflammatory PCD mode driven by the PANoptosome complex, which synchronously triggers the characteristic events of three death pathways in the same cell through the cooperative integration of the core molecular components of pyroptosis, apoptosis, and necroptosis. In this process, cysteinyl aspartate-specific proteinase-8 (Caspase-8) and receptor-interacting serine/threonine kinase 3 (RIPK3), as the core components of the PANoptosome, jointly determine whether the cell goes to a single programmed death or an integrated PANoptosis. The limited studies' evidence supports that CaOx crystals induce concurrent activation of apoptosis, pyroptosis, and necroptosis, suggesting the possibility of PANoptosis in CaOx\u2011induced kidney injury. At the same time, the rupture of the cell membrane caused by PANoptosis, similar to other forms of PCD, releases a large number of damage-associated molecular patterns (DAMPs), which activate innate immunity to form an inflammatory cascade and further aggravates tissue damage. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. In the future, new biomarkers and multi-target intervention strategies should be developed based on PANoptosis, which is expected to open up a new path for the prevention and treatment of CaOx-induced kidney injury.\n\nID: 42453609\nTitle: PANoptosis in neurological disorders: from inflammatory cell death mechanisms to neuroprotective strategies.\nAbstract: PANoptosis is now regarded as an inflammatory form of programmed cell death (PCD). It reflects the coordinated involvement of apoptosis, pyroptosis, and necroptosis, usually through the PANoptosome in a shared pathological environment. This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. Neural tissue is particularly sensitive to oxidative stress, mitochondrial dysfunction, immune-mediated inflammation, and blood-brain barrier disruption. These pathological changes are common in many forms of neural injury. Therefore, abnormal PANoptosis activation may provide a common mechanism linking different types of nervous system damage. This review summarizes the historical evolution, molecular mechanisms, disease-related roles, and intervention strategies of PANoptosis in neurological disorders. It focuses on PANoptosome assembly and key mechanistic nodes, including NOD-like receptor family pyrin domain-containing 3 (NLRP3), caspase-8, the receptor-interacting serine/threonine protein kinase 1 (RIPK1)/receptor-interacting serine/threonine protein kinase 3 (RIPK3)/mixed lineage kinase domain-like protein (MLKL) axis, gasdermin D (GSDMD), and Ninjurin 1 (NINJ1). It also highlights current translational limitations, such as disease heterogeneity, incomplete cell-specific validation, and insufficient clinical evidence.\n\nID: 42450339\nTitle: The Immunologic Function of the Choroid Plexus: A Gateway to Immunomodulatory Therapy in Injury Models of the Central Nervous System.\nAbstract: Over time, our understanding of the central nervous system (CNS) as an immunologically privileged site where immune-cell infiltration takes place has changed; research has transformed the dominant view, showing that the CNS is an immunologically specialized tissue featuring complex interactions between the immune system and CNS processes, where the choroid plexus (CP) has an essential role in regulating neuronal tissue homeostasis and immune-cell trafficking. Although immune-cell entry into the CNS is tightly controlled, small numbers of antigen-experienced lymphocytes can access cerebrospinal fluid (CSF) compartments for immune surveillance under normal conditions. During an injury, such as cerebral ischemia or spinal cord damage, dendritic cell precursors infiltrate the CNS, suggesting their involvement in modulating lymphocyte activity. However, the immunoregulatory function of the CP alone is insufficient to prevent damage. Injury can trigger a cascade of events including activation of microglia toward a pro-inflammatory M1 phenotype, infiltration of peripheral immune cells across the blood-brain barrier (BBB), and uncontrolled neuroinflammation. T cells play a critical role in this process. Th1 cells exacerbate inflammation upon recognizing neural antigens, whereas Th2 cells promote recovery by releasing neurotrophic factors. This highlights the dual role of inflammation in CNS injury and repair.\n\nID: 42450046\nTitle: Time-Resolved Label-Free Proteomics of SHK-1 Cells After Renibacterium salmoninarum Inoculation Reveals Early Host-Cell Remodeling.\nAbstract: Renibacterium salmoninarum, the etiological agent of bacterial kidney disease, is a facultative intracellular pathogen whose interaction with salmonid phagocytic cells remains poorly resolved at the protein level. Here, we aimed to define the temporal protein-abundance architecture of SHK-1 macrophage-like cells after R. salmoninarum inoculation and to test whether this response supports broad canonical cell-death pathway engagement. We used label-free quantitative LC-MS/MS proteomics to profile SHK-1 cells over a 48 h post-inoculation time course. Because the design included a single non-infected T0 baseline, analyses were framed as baseline-referenced post-inoculation comparisons rather than a fully controlled mock time course. Of 6842 proteins retained for statistical modeling, 2254 were strictly differentially abundant in at least one contrast relative to T0 (adjusted p < 0.05 and |log2FC| \u2265 0.585). Perturbation was strongest at 1-2 h and progressively contracted at later time points. Among 1278 recurrent proteins, k-means clustering resolved four temporal modules capturing coordinated remodeling of lysosomal, immunometabolic, cytoskeletal, stress-response, and antioxidant programs. A curated cell-death panel spanning apoptosis, pyroptosis, necroptosis, ferroptosis, and PANoptosis yielded only three detected markers; CASP3 and MLKL met the strict threshold, whereas ACSL4 remained sub-threshold. Overall, early host-cell remodeling, rather than broad canonical death-program execution, was the predominant proteomic signature of SHK-1 cells during the first 48 h after R. salmoninarum inoculation.\n\nID: 42449982\nTitle: Role of Supraspinal Neuroinflammation in Chronic Pain After Experimental Spinal Cord Injury-A Systematic Review.\nAbstract: Spinal cord injury (SCI) is a major cause of long-term disability and is frequently accompanied by chronic pain, substantially reducing quality of life. Although spinal neuroinflammation is a recognized contributor to neuropathic pain, the role of supraspinal neuroinflammation remains less well defined. This systematic review critically evaluated experimental evidence linking SCI-induced supraspinal neuroinflammation with pain-related behaviors in animal models. A systematic literature search in PubMed, Web of Science Core Collection, and Scopus identified studies published over the last 20 years using rodent SCI models that assessed both supraspinal neuroinflammatory markers and pain-related behaviors. After screening, nine studies met the predefined criteria. The analyzed studies suggested that SCI is associated with supraspinal neuroinflammatory alterations, including increased microglial and astrocytic activation and upregulation of pro-inflammatory cytokines and chemokine-related pathways, in several brain regions. In intervention studies, reduced neuroinflammation was accompanied by improvement in mechanical or thermal pain-related behaviors. However, considerable methodological heterogeneity and moderate to high risk of bias were observed. Current evidence suggests an association between supraspinal neuroinflammatory alterations and chronic pain-related behaviors after SCI, but the limited number of studies and methodological variability restrict firm conclusions. Further well-designed experimental studies are needed to clarify underlying mechanisms.\n\nID: 42446837\nTitle: Molecular Regulation of Pyroptosis in Alzheimer's Disease: Linking Neuroinflammation, Cell Death, and Therapeutic Targeting.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by profound cognitive decline, wherein chronic neuroinflammation plays a pivotal pathogenic role. Central to this inflammatory milieu is pyroptosis, a highly inflammatory form of programmed lytic cell death mediated by gasdermin proteins. This comprehensive review provides an in-depth synthesis of the cellular and molecular mechanisms underlying pyroptosis in AD. We detail the distinct roles of microglia as primary initiators responding to amyloid-beta (A\u03b2) and tau aggregates, alongside the specific vulnerabilities of neurons facing oxidative stress, astrocytes impacting metabolic support, and endothelial cells whose pyroptotic death contributes directly to blood-brain barrier disruption. At the molecular level, the priming and activation of the NLRP3 and NLRP1 inflammasomes by diverse triggers, including classical markers like A\u03b2, environmental neurotoxicants and metabolic stressors, converge on caspase-1 and caspase-8 activation. This cascade culminates in gasdermin D (GSDMD) and gasdermin E (GSDME) pore formation, leading to cellular lysis and the massive release of pro-inflammatory cytokines such as IL-1\u03b2 and IL-18. Furthermore, this paper explores the emerging and critical concept of PANoptosis, highlighting the intricate crosstalk between pyroptosis, apoptosis, and necroptosis within PANoptosome complexes triggered by mitochondrial dysfunction. We evaluate current and prospective therapeutic strategies, ranging from multi-target natural and traditional herbal remedies to advanced nanomedicine, synthetic small molecules, and epigenetic gene therapies. By integrating insights from blood-based pyroptosis-associated molecular signatures and advanced targeted drug delivery systems, we emphasize the critical need for personalized, multi-targeted approaches to successfully harness pyroptosis modulation in the clinical management and treatment of AD.\n\nID: 42437012\nTitle: Taurochenodeoxycholic acid alleviates MPP+/MPTP-induced neurotoxicity in vitro and in vivo by suppressing ferroptosis via TGR5/cGAS/STING signaling pathway.\nAbstract: Parkinson's disease (PD) is characterized by progressive loss of dopaminergic neurons in the substantia nigra, with ferroptosis emerging as critical pathogenic mechanisms. Recent evidence suggests that STING activation can induce neuronal ferroptosis through autophagic degradation of GPX4. Taurochenodeoxycholic acid (TCDCA), a naturally occurring bile acid, has demonstrated neuroprotective properties through activation of Takeda G protein-coupled receptor 5 (TGR5). However, whether TCDCA can improve PD by modulating the cGAS-STING-ferroptosis axis remains unexplored. We investigated the effects of TCDCA treatment on motor function, dopaminergic neuronal survival, oxidative stress markers, ferroptosis-related proteins (GPX4, SLC7A11, ACSL4), and cGAS-STING signaling components in the substantia nigra of male mice subjected to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration and in MPP\u207a-treated SH-SY5Y cells. Behavioral assessments demonstrated that TCDCA significantly improved motor dysfunction in both open field and pole tests. TCDCA treatment markedly increased tyrosine hydroxylase-positive neurons and reduced oxidative stress markers including malondialdehyde and ferrous iron levels while restoring superoxide dismutase activity and glutathione content in the substantia nigra. Results showed that TCDCA upregulated TGR5 expression and concurrently suppressed cGAS and STING activation in both in vivo and in vitro PD models. Importantly, TCDCA treatment significantly enhanced the expression of anti-ferroptotic proteins GPX4 and SLC7A11 while reducing pro-ferroptotic ACSL4. These neuroprotective effects were associated with TGR5 upregulation and cGAS-STING pathway suppression. Our findings demonstrate that TCDCA alleviates PD-related neurodegeneration by inhibiting cGAS-STING-mediated ferroptosis through TGR5 activation, suggesting that TCDCA holds promise as a candidate drug for the treatment of PD.\n\nID: 42510899\nTitle: Stem Cell-Based Strategies for Fibrotic and Neurogenic Bladder Disorders: Current Evidence, Translational Challenges, and Future Directions.\nAbstract: Progressive bladder fibrosis and impaired detrusor function represent converging pathological endpoints across diverse bladder disorders, including bladder outlet obstruction (BOO) associated with benign prostatic hyperplasia, spinal cord injury (SCI)-induced neurogenic bladder, radiation cystitis, and interstitial cystitis/bladder pain syndrome. Conventional therapies primarily manage symptoms and rarely reverse established fibrosis or restore durable bladder homeostasis. Mesenchymal stem/stromal cells (MSCs) have attracted considerable interest as therapeutic agents owing to their antifibrotic, immunomodulatory, angiogenic, and trophic paracrine activities. This review synthesises six key studies from our group and places them within the broader international literature on bladder regenerative medicine: (i) feasibility of superparamagnetic iron oxide (SPIO)-based molecular MRI tracking of transplanted human MSCs (hMSCs) in the bladder; (ii) SPIO-hMSC therapy for BOO-associated fibrosis with concurrent MRI monitoring; (iii) hepatocyte growth factor (HGF)-overexpressing engineered hMSC (B10.HGF) therapy in BOO; (iv) hMSC transplantation into the SCI-injured bladder wall monitored by MRI; (v) systematic review and meta-analysis of stem cell therapy effects on urodynamic outcomes in SCI models; and (vi) HGF-overexpressing hMSC therapy for BOO-induced underactive bladder. These six key studies are contextualised within the broader literature addressing cell sources, biomaterial-assisted delivery platforms, mechanistic pathways, emerging clinical evidence, and the evolving regulatory landscape for cell-based advanced therapy medicinal products. Key translational challenges include product standardisation, long-term durability, and mechanism-linked potency assay development.\n\nID: 42446158\nTitle: Host immune determinants of stromal vascular fraction graft survival: Toward a concept of SVF therapy resistance - A systematic narrative review.\nAbstract: Stromal vascular fraction (SVF)-based therapies and autologous fat grafting have emerged as promising regenerative strategies due to their pro-angiogenic, immunomodulatory, and trophic properties. However, despite encouraging preclinical and clinical findings, therapeutic outcomes remain highly heterogeneous, with marked variability in graft retention and functional efficacy between patients. Increasing evidence suggests that this variability cannot be explained solely by procedural factors or cellular composition, but may also depend on host-related immune and microenvironmental determinants. This review explores the biological mechanisms governing SVF engraftment and introduces the emerging concept of \"SVF therapy resistance,\" defined as the failure of autologous regenerative therapies resulting from maladaptive interactions between transplanted stromal cells and the host tissue environment. Particular attention is given to sterile inflammation, innate immune activation, and early graft-host interactions. Following transplantation, tissue injury and ischemia induce the release of danger-associated molecular patterns (DAMPs), triggering neutrophil recruitment, macrophage activation, complement signaling, and inflammatory remodeling. While controlled inflammatory responses may support tissue repair and angiogenesis, excessive neutrophil activation, neutrophil extracellular trap (NET) formation, persistent pro-inflammatory macrophage polarization, and impaired vascular adaptation may compromise graft survival and regenerative efficacy. The review further discusses how SVF processing, inflammatory priming, stromal cell heterogeneity, and donor-related factors-including obesity, aging, metabolic dysfunction, and chronic inflammation-may influence therapeutic responsiveness. Emerging evidence from mesenchymal stromal cell biology suggests that stromal cells are highly sensitive to inflammatory licensing and microenvironmental cues. Candidate biomarkers and immune profiling strategies capable of identifying responders and non-responders to SVF-based therapies are also reviewed. Finally, these mechanisms are discussed in spinal cord injury, a condition characterized by chronic inflammation and vascular dysfunction. Overall, this review proposes a translational framework linking innate immunity, sterile inflammation, angiogenesis, and stromal cell heterogeneity to the variability of SVF therapy outcomes, highlighting the need for personalized regenerative medicine approaches.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures. Key findings were further evaluated using an external human SCI-related cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and published single-cell RNA-seq data. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. External validation in a human SCI-related peripheral blood cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and single-cell reanalysis further supported the upregulation of CD14 and its association with myeloid inflammatory activation and pyroptosis-, necroptosis-, and ferroptosis-related signatures. Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI.\n  --- END ACTUAL ABSTRACT FOR 42519304 ---\n\n- ERROR: You cited ID: 42499235 for the quote: \"We identified several candidate necroptosis-related genes... toll-like receptor 4 (Tlr4), Nlrp3, Il1b, Tnfaip3, and Stat4.\"\n  FACT: Ellipses (...) are strictly forbidden.

In this study, we aimed to identify and validate key genes associated with necroptosis in SCI using bulk RNA-seq data, followed by differential analysis and weighted gene coexpression network analysis (WGCNA). We identified several candidate necroptosis-related genes, and further least absolute shrinkage and selection operator (LASSO) regression highlighted five SCI-necroptosis differentially expressed genes (DEGs): toll-like receptor 4 (Tlr4), Nlrp3, Il1b, Tnfaip3, and Stat4. These genes were validated using RT-qPCR and western blot experiments. Our analysis revealed that necroptosis scores were significantly elevated following SCI. Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) analysis revealed that Tlr4 was upregulated in myeloid cells (microglia and macrophages) and played a pivotal role in triggering downstream necroptosis, which was confirmed by protein levels. In vitro and in vivo experiments confirmed that Tlr4 inhibition attenuated necroptosis and inflammation. This study is the first to establish Tlr4 as a direct upstream regulator of the pRIPK1/pRIPK3/pMLKL necroptotic axis in SCI, distinct from its role as a general inflammatory mediator, suggesting Tlr4 as a promising therapeutic target for functional recovery.\n  --- END ACTUAL ABSTRACT FOR 42499235 ---\n\n- ERROR: You cited ID: 42498720 for the quote: \"Genetic deletion of Plin2 markedly reduced lipid droplet burden, attenuated neuroinflammation, and promoted neuronal survival.\"\n  FACT: Strict Misquote Detected!

While microglial lipid metabolic reprogramming, particularly lipid droplet accumulation, has been implicated in chronic inflammation, the underlying mechanisms remain poorly understood. Using single-cell transcriptomics, we identified a previously defined lipid droplet-accumulating microglia (LDAM) subpopulation in spinal cord injury (SCI), characterized by elevated PLIN2 expression. Genetic deletion of Plin2 markedly reduced lipid droplet burden, attenuated neuroinflammation, and promoted neuronal survival and functional recovery in vivo. Mechanistically, PLIN2 interacts with the mitochondrial outer membrane protein PGAM5 to regulate lipid droplet-mitochondria contacts. This interaction inverts canonical metabolic flux by redirecting fatty acids from mitochondria back to lipid droplets, thereby suppressing \u03b2-oxidation and inducing mitochondrial dysfunction, which subsequently triggers STING-dependent inflammation. Notably, the PLIN2 220-392 domain is essential for PGAM5 binding and contact formation; disrupting this interaction attenuates STING signaling and enhances neuroprotection and functional recovery in vivo. Our findings identify the PLIN2-PGAM5 as a critical metabolic-immune pathway and suggest that targeting organelle-contact-mediated metabolic reprogramming represents a potential therapeutic strategy for CNS injury.\n  --- END ACTUAL ABSTRACT FOR 42498720 ---\n\n- ERROR: You cited ID: 42521977 for the quote: \"RCD-guided phenotyping integrates pyroptosis, NETosis, ferroptosis, necroptosis, and PANoptosis pathways to systematically redefine SIC.\"\n  FACT: Strict Misquote Detected!

Brains and spinal cords were collected 2-3\u00a0weeks post-injection or between 6-10 and 11-15\u00a0months of age. Immunohistochemical studies of transgene expression throughout the brain and spinal cord using an antibody selective for human APP (hAPP) revealed age-dependent accumulation of clusters of hAPP-positive granules in areas containing hAPP-labeled neuronal cell bodies. Surprisingly, there were also hAPP-positive granules in regions containing axons and synaptic terminals from hAPP expressing neurons. Moreover, tdT expressed by CSNs accumulated in the same granules as hAPP, and both tdT and hAPP were present in clusters of granules with other markers of AD pathology. Quantitative assessments confirmed age-related degeneration of layer V CSNs accompanied by progressive accumulation of clusters of tdT and hAPP-positive granules. Overall, our results indicate that accumulation of aggregated hAPP in areas containing axons and synaptic terminals from hAPP expressing neurons is a prominent feature of AD pathophysiology in 5xFAD mice and that accumulation of clusters of hAPP granules provides a secondary measure to track neurodegeneration of identified populations of genetically labeled neurons.\n  --- END ACTUAL ABSTRACT FOR 42431350 ---\n\n- ERROR: You cited ID: 42317798 for the quote: \"Mechanistically, SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis.\"\n  FACT: Strict Misquote Detected!

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma.\n  --- END ACTUAL ABSTRACT FOR 42317798 ---\n\n- ERROR: You cited ID: 42510529 for the quote: \"Compound 20... markedly counteracted A\u03b2(25-35)-induced ferroptotic damage by restoring intracellular glutathione levels, depleting the labile iron pool, and suppressing lipid peroxidation.\"\n  FACT: Ellipses (...) are strictly forbidden.

Building on our previous work, which identified compound 20 as a promising antioxidant and neuroprotective agent, the present study investigates the molecular mechanisms underlying its protective activity against amyloid-induced ferroptosis in human neuroblastoma SH-SY5Y cells exposed to A\u03b2(25-35). Compound 20 (3-(((4-hydroxybenzyl)(methyl)amino)methyl)-1-methyl-N-(2-(piperazin-1-yl)ethyl)-1H-indole-5-carboxamide) markedly counteracted A\u03b2(25-35)-induced ferroptotic damage by restoring intracellular glutathione levels, depleting the labile iron pool, and suppressing lipid peroxidation. In parallel, the compound significantly rescued mitochondrial membrane potential and attenuated endoplasmic reticulum (ER) expansion associated with ER stress, thereby preserving cellular homeostasis under oxidative challenge. These protective effects were further corroborated by real-time PCR analysis, which revealed the modulation of key genes involved in the oxidative stress response, endoplasmic reticulum stress, and inflammatory pathways. To gain a systems-level insight into these mechanisms, untargeted 1H-NMR metabolomic profiling was performed. This analysis confirmed the activation of antioxidant pathways and disclosed a significant modulation of energy metabolism and GABA-related pathways, both of which are closely linked to redox balance and neuronal resilience. Overall, these findings demonstrate that compound 20 drives metabolic reprogramming that orchestrates its multifactorial protective effect against A\u03b2(25-35)-induced ferroptosis by coordinating antioxidant defense, iron homeostasis, and ER stress mitigation.\n  --- END ACTUAL ABSTRACT FOR 42510529 ---\n\n- ERROR: You cited ID: 42426407 for the quote: \"MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity.\"\n  FACT: Strict Misquote Detected!

The degenerative disc's harsh microenvironment promotes nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) death and hinders self repair. Mesencephalic astrocyte-derived neurotrophic factor (MANF), an atypical neurotrophic factor, has protective effects in degenerative diseases. However, its role in IDD is unclear. Assessment of MANF expression was conducted in both human nucleus pulposus tissues and a rat IVD puncture model. An in vitro model of degeneration was established by acid treatment of NP-MSCs, and the functional role of MANF was explored through its knockdown and overexpression. RNA sequencing was employed to identify downstream targets. The therapeutic potential of MANF-overexpressing NP-MSCs was evaluated in a rat puncture model. MANF expression was markedly downregulated in degenerated IVD tissues from both human patients and rat models. Correspondingly, in vitro experiments demonstrated that MANF knockdown exacerbated, while its overexpression mitigated, acid-induced apoptosis of NP-MSCs. Mechanistically, MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity, as demonstrated by the complete abolition of this protection upon treatment with the MAM uncoupler FATE1. Transcriptomic analysis and subsequent validation identified receptor expression-enhancing protein 1 (REEP1) as a critical downstream effector through which MANF safeguards MAM integrity. We further elucidated that MANF upregulates REEP1 expression by directly inhibiting miR-33b-5p. In vivo, transplantation of MANF-overexpressing NP-MSCs effectively attenuated IDD in a rat model. MANF protected NP-MSCs from acidosis by sustaining MAM integrity via the MiR-33b-5p/REEP1 axis. These findings reveal MANF's mechanism and therapeutic potential for IDD.\n  --- END ACTUAL ABSTRACT FOR 42426407 ---\n\n- ERROR: You cited ID: 42501927 for the quote: \"We summarize how apoptosis, necroptosis, pyroptosis, and ferroptosis operate as an interlocking network in autoimmune microenvironments, frequently co-existing as context-dependent mixed-death states.\"\n  FACT: Strict Misquote Detected!

Increasing evidence indicates that regulated cell death (RCD) can act as an upstream amplifier in selected autoimmune settings, while in other settings it may mainly report downstream collateral injury caused by cytotoxic lymphocytes, immune complexes, complement activation, or tissue hypoxia. Accordingly, this review distinguishes causal death execution from associative pathway signatures and highlights the types of longitudinal, cell-type-resolved, and perturbational evidence needed to make that distinction. We summarize how apoptosis, necroptosis, pyroptosis, and ferroptosis operate as an interlocking network in autoimmune microenvironments, frequently co-existing as context-dependent mixed-death states driven by shared triggers such as cytokines, PRR ligands, and oxidative stress, and governed by decision hubs including RIPK1 and caspase-8. We highlight integrated concepts such as PANoptosis to explain pathway convergence and compensatory switching into parallel lytic branches when a single node is constrained. The review further connects mechanistic insights to translational priorities, emphasizing biomarker strategies that report pathway engagement, targeted modulation of executors or upstream sensing and cytokine circuits, and lesion-localized delivery approaches to improve the therapeutic window. Finally, we outline key gaps that must be addressed to enable precision interventions, including spatial and cell-type resolved validation of death programs, longitudinal profiling across flare-remission trajectories, and harmonized composite panels capable of capturing mixed-death dynamics in heterogeneous AIDs.\n  --- END ACTUAL ABSTRACT FOR 42501927 ---\n\n- ERROR: You cited ID: 42506907 for the quote: \"restoring NAD+ inhibited PANoptosis but not the other forms of cell death.

While these responses can be beneficial in host defense, aberrant activation of inflammatory, lytic cell death pathways can be pathogenic. Emerging evidence suggests that cellular metabolic disruption can promote inflammatory cell death, but the mechanistic connections between these processes are not well understood, limiting our ability to identify regulatory nodes that can be therapeutically targeted. Here, we found that intracellular levels of the metabolic cofactor nicotinamide adenine dinucleotide (NAD+) were depleted in response to cell death triggers that drive pyroptosis, necroptosis, PANoptosis, and ferroptosis. However, restoring NAD+ inhibited PANoptosis but not the other forms of cell death. Mechanistically, NAD+ restoration reduced the expression of PANoptotic sensors or regulators, including the transcription factor IRF1, a critical factor for innate immune sensor priming in PANoptosis. Our findings thereby suggest that NAD+ depletion is an early cell death signaling event and that restoring NAD+ levels specifically blocks PANoptosis by suppressing priming. Hence, targeting NAD+ metabolism represents a potential therapeutic strategy for infectious and inflammatory diseases associated with dysregulated PANoptosis.\n  --- END ACTUAL ABSTRACT FOR 42506907 ---\n\n- ERROR: You cited ID: 42484540 for the quote: \"WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals... reduced CGRP\u2009+\u2009structures in the dorsal horn.\"\n  FACT: Ellipses (...) are strictly forbidden.

Here, we assessed the post-SCI pain-associated behavior index (PAB, based on established behavioral criteria) and compared synapse counts (SYN+, VGLUT1+, ChAT+, VGAT+), CGRP+- and SER+-structures, as well as astrocytic and microglial populations in the lumbar dorsal horn following thoracic SCI in WBV-treated and untreated rats. Animals received WBV from postoperative week 3 to 12, and outcomes were compared with non-treated controls. PAB was consistently reduced in WBV-treated animals. STED-microscopy quantification showed that WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals, as well as the number of SER\u2009+\u2009fibers. Conversely, WBV reduced CGRP\u2009+\u2009structures in the dorsal horn, decreased the density of CGRP\u2009+\u2009perisomatic and axo-axonic synapses, and lowered astrocytic and microglial populations. Our data indicate that the WBV-induced frequent (15-30\u2005Hz) muscle contractions and proprioceptive impulses contribute to spasticity modulation (via VGAT-related mechanisms) and attenuation of post-SCI hyperalgesia (CGRP-associated). Together with the reduced astro- and microglia amounts, the described synaptic alterations are considered essential prerequisites for better motor recovery. These findings provide preclinical evidence for the functional benefits of WBV in an animal SCI model and warrant further investigations to determine mechanisms underpinning this non-invasive, low-cost and easily applicable rehabilitation approach.\n  --- END ACTUAL ABSTRACT FOR 42484540 ---\n\n- ERROR: You cited ID: 42490372 for the quote: \"these studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate.\"\n  FACT: Strict Misquote Detected!

These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors.\n  --- END ACTUAL ABSTRACT FOR 42490372 ---\n\n- ERROR: You cited ID: 42422221 for the quote: \"EsA exerts a neuroprotective effect against SCI by modulating oxidative stress and neuronal apoptosis partially through activation of the Nrf2/HO-1 pathway.\"\n  FACT: Strict Misquote Detected!

Neuronal apoptosis constitutes a critical pathological event leading to neurological dysfunctions, which is further exacerbated by oxidative stress following SCI. Esculentoside A (EsA), a bioactive saponin isolated from Phytolaca esculenta, exhibits neuroprotective potential in our preliminary studies. However, whether EsA attenuates oxidative stress and neuronal apoptosis in SCI remains unclear. The current study aimed to investigate the protective potential of EsA against oxidative stress and neuronal apoptosis following SCI, and to elucidate the associated molecular mechanisms. SCI was modeled in rats via contusion using the PSI-IH 0400 Striker impactor, and rats were treated intraperitoneally with 10 mg/kg EsA once daily. The Basso, Beattie, and Bresnahan (BBB) scale, grid walk analysis, and footprint test were adopted to evaluate motor function dynamically. Histopathological alterations in spinal cord tissue were examined by Hematoxylin-eosin (HE), Luxol Fast Blue (LFB), and Nissl staining. Oxidative stress markers, including hydrogen peroxide (H2O2) and malondialdehyde (MDA), along with antioxidant enzymes glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD), were quantified in spinal cord homogenates using commercial assay kits. Western blot, immunofluorescence staining, and molecular docking were employed to investigate the underlying mechanisms. EsA significantly improved motor function and reduced histopathological damage in SCI rats. This neuroprotective effect was accompanied by a significant improvement in oxidative stress biomarkers and neuronal apoptosis in the injured spinal cord, coinciding with activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. In conclusion, EsA exerts a neuroprotective effect against SCI by modulating oxidative stress and neuronal apoptosis partially through activation of the Nrf2/HO-1 pathway, indicating its promise as a therapeutic agent for SCI.\n  --- END ACTUAL ABSTRACT FOR 42422221 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury.\" (Source: 42519304)\n- \"PLIN2 interacts with the mitochondrial outer membrane protein PGAM5 to regulate lipid droplet-mitochondria contacts.\" (Source: 42498720)\n- \"PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury.\" (Source: 42456380)\n- \"This concept may be especially useful in neurological diseases.

Recent literature suggests that CD14 serves as a robust candidate hub gene associated with myeloid inflammatory activation and lytic cell death signatures. While direct clinical evidence for CD14 inhibition as a singular PANoptosome-blocking strategy remains in the exploratory phase, the integration of CD14 into the broader framework of lytic cell death regulation provides a compelling mechanistic target to mitigate the progressive neuroinflammatory feed-forward loop.\n\n### [INTRODUCTION & JUSTIFICATION]\nSecondary injury after spinal cord injury (SCI) is a multifaceted pathological process characterized by persistent inflammation, oxidative stress, and multiple forms of programmed cell death (PCD). The literature identifies that lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. Crucially, the discovery that CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures highlights its potential role as a gatekeeper of the inflammatory response. \n\nThe mechanism by which this cell death occurs involves a complex coordination between metabolic and inflammatory pathways. For instance, PLIN2 interacts with the mitochondrial outer membrane protein PGAM5 to regulate lipid droplet-mitochondria contacts. This relationship is critical, as Genetic deletion of Plin2 markedly reduced lipid droplet burden, attenuated neuroinflammation, and promoted neuronal survival and functional recovery in vivo. These metabolic perturbations are not isolated; rather, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This dysfunction facilitates the \"ferroptotic storm,\" described as Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. \n\nFurthermore, the integration of multiple cell death pathways into a unified, inflammatory lytic model\u2014PANoptosis\u2014offers a critical framework for therapeutic intervention. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. The rationale for targeting these pathways in the central nervous system is that This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. As CD14 appears as a primary coordinator of these myeloid-driven lytic signatures, its inhibition may interrupt the cross-talk between ferroptotic lipid signaling and PANoptosome assembly, thereby limiting the secondary inflammatory cascade.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   CD14 acts as an upstream candidate hub gene connecting myeloid activation to the execution of lytic cell death in SCI.\n*   The interaction between PLIN2 and PGAM5 provides a targetable metabolic switch that can mitigate the \"ferroptotic storm\" inherent in secondary injury.\n*   Mitochondrial dysfunction serves as a \"central rheostat\" that synchronizes the execution of necroptosis across different cellular models.\n*   PANoptosis provides a unifying conceptual model to resolve why single-pathway inhibition (e.g., anti-pyroptotic alone) often fails in clinical or complex models.\n*   Metabolic stress, specifically NAD+ depletion, selectively controls the susceptibility of cells to PANoptotic signaling.\n*   Bioactive interventions, such as BoNT/A or exercise-derived exosomes, demonstrate that structural and functional recovery requires simultaneous multi-axis modulation of inflammatory and apoptotic markers.\n*   The complexity of protein-ligand interactions, such as NADH recognition, highlights the necessity for precise, structural-based inhibitor design to manage neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Mesenchymal stem cell-based treatment has become a promising therapy for neuroinflammation-associated diseases. However, the effects of mesenchymal stem cells are controversial, and the underlying mechanism is incompletely understood. In the present study, menstrual blood-derived endometrial stem cells were intravenously transplanted into a mouse model of neuroinflammation established by peripheral injection of lipopolysaccharide. Microglial cells challenged with lipopolysaccharide were cultured with conditioned medium from endometrial stem cells. The levels of cytokines were detected by enzyme-linked immunosorbent assay. Cell proliferation and death were detected by Cell Counting Kit 8 and flow cytometry, respectively. The expression levels of Toll-like receptor 4 (TLR4), myeloid differentiation primary response gene 88 (MyD88), NLR family pyrin domain containing 3 (NLRP3) and caspase 1 (Casp1) were evaluated by western blotting. The results showed that intravenous transplantation of endometrial stem cells downregulated proinflammatory factors and upregulated anti-inflammatory factors in the brain of mice with neuroinflammation. Conditioned medium suppressed the inflammatory reaction and hyperactivation of microglial cells and protected microglial cells from cell death induced by lipopolysaccharide in vitro. The expression of TLR4, MyD88, NLRP3 and Casp1 in the brain of mice with neuroinflammation and in lipopolysaccharide-stimulated microglial cells was downregulated by endometrial stem cells and conditioned medium, respectively. These data suggested that menstrual blood-derived endometrial stem cells may suppress neuroinflammatory reactions partially by regulating microglia through the TLR4/MyD88/NLRP3/Casp1 signalling pathway. Our findings may be very useful for the development of an alternative stem cell-based therapy for neuroinflammation-associated disorders.",
        "36765034": "ID: 36765034\nTitle: IRAK-M suppresses the activation of microglial NLRP3 inflammasome and GSDMD-mediated pyroptosis through inhibiting IRAK1 phosphorylation during experimental autoimmune encephalomyelitis.\nAbstract: The activation of the NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) inflammasome triggers pyroptosis proinflammatory cell death in experimental autoimmune encephalomyelitis (EAE). However, the underlying mechanisms of the inflammatory processes of microglia in EAE remain unclear. Our previous studies suggested that interleukin-1 receptor-associated kinase (IRAK)-M down-regulates the toll-like receptor 4/interleukin-1 receptor signaling pathway. Here, we used IRAK-M knockout (IRAK-M-/-) mice and their microglia to dissect the role of IRAK-M in EAE. We found that deletion of IRAK-M increased the incidence rate and exacerbated the clinical symptoms in EAE mice. We then found that IRAK-M deficiency promoted the activation of microglia, activated NLRP3 inflammasomes, and enhanced GSDMD-mediated pyroptosis in the microglia of EAE. In contrast, over-expression of IRAK-M exerted inhibitory effects on neuroinflammation, NLRP3 activation, and pyroptosis. Moreover, IRAK-M deficiency enhanced the phosphorylation of IRAK1, while IRAK-M over-expression downregulated the level of phosphorylated IRAK1. Finally, we found upregulated binding of IRAK1 and TNF receptor-associated factor 6 (TRAF6) in IRAK-M-/- EAE mice compared to WT mice, which was blocked in AAVIRAK-M EAE mice. Our study reveals a complex signaling network of IRAK-M, which negatively regulates microglial NLRP3 inflammasomes and pyroptosis by inhibiting IRAK1 phosphorylation during EAE. These findings suggest a potential target for the novel therapeutic approaches of multiple sclerosis (MS)/EAE and NLRP3-related inflammatory diseases.",

This protein carries out a neuronal cell-death-mode switch from necrosis to apoptosis, which is, in turn, suppressed by a variety of neurotrophic factors (NTFs). This type of NTF-assisted survival action of ProT\u03b1 is reproduced in cerebral and retinal ischemia-reperfusion models. Further studies that used a retinal ischemia-reperfusion model revealed that ProT\u03b1 protects retinal cells via ecto-F1 ATPase coupled with the Gi-coupled P2Y12 receptor and Toll-like receptor 4 (TLR4)/MD2 coupled with a Toll-IL-1 receptor domain-containing adaptor inducing IFN-\u03b2 (TRIF). In cerebral ischemia-reperfusion models, ProT\u03b1 has additional survival mechanisms via an inhibition of matrix metalloproteases in microglia and vascular endothelial cells. Heterozygous or conditional ProT\u03b1 knockout mice show phenotypes of anxiety, memory learning impairment, and a loss of neurogenesis. There are many reports that ProT\u03b1 has multiple intracellular functions for cell survival and proliferation through a variety of protein-protein interactions. Overall, it is suggested that ProT\u03b1 plays a key role as a brain guardian against ischemia stress through a cell-death-mode switch assisted by NTFs and a role of neurogenesis.",
        "36803990": "ID: 36803990\nTitle: Regulatory T cells alleviate myelin loss and cognitive dysfunction by regulating neuroinflammation and microglial pyroptosis via TLR4/MyD88/NF-\u03baB pathway in LPC-induced demyelination.\nAbstract: Demyelination occurs in multiple central nervous system (CNS) disorders and is tightly associated with neuroinflammation. Pyroptosis is a form of pro-inflammatory and lytic cell death which has been observed in CNS diseases recently. Regulatory T cells (Tregs) have exhibited immunoregulatory and protective effects in CNS diseases. However, the roles of Tregs in pyroptosis and their involvement in LPC-induced demyelination have not been explicated. In our study, Foxp3-diphtheria toxin receptor (DTR) mice treated with diphtheria toxin (DT) or PBS were subjected to two-site lysophosphatidylcholine (LPC) injection. Immunofluorescence, western blot, Luxol fast blue (LFB) staining, quantitative real-time PCR (qRT-PCR) and neurobehavior assessments were performed to evaluate the severity of demyelination, neuroinflammation and pyroptosis. Pyroptosis inhibitor was further used to investigate the role of pyroptosis in LPC-induced demyelination. RNA-sequencing was applied to explore the potential regulatory mechanism underlying the involvement of Tregs in LPC-induced demyelination and pyroptosis. Our results showed that depletion of Tregs aggravated microgliosis, inflammatory responses, immune cells infiltration and led to exacerbated myelin injury as well as cognitive defects in LPC-induced demyelination. Microglial pyroptosis was observed after LPC-induced demyelination, which was aggravated by Tregs depletion. Inhibition of pyroptosis by VX765 reversed myelin injury and cognitive function exacerbated by Tregs depletion. RNA-sequencing showed TLR4/myeloid differentiation marker 88 (MyD88) as the central molecules in Tregs-pyroptosis pathway, and refraining TLR4/MyD88/NF-\u03baB pathway alleviated the aggravated pyroptosis induced by Tregs depletion. In conclusion, our findings for the first time indicate that Tregs alleviate myelin loss and improve cognitive function by inhibiting pyroptosis in microglia via TLR4/MyD88/NF-\u03baB pathway in LPC-induced demyelination.",
        "37277081": "ID: 37277081\nTitle: Saikosaponin B2 ameliorates depression-induced microglia activation by inhibiting ferroptosis-mediated neuroinflammation and ER stress.\nAbstract: Saikosaponins B2 (SSB2) is one of the main active components isolated from Radix Bupleuri (Bupleurum chinense DC.), a herb widely used of traditional Chinese medicine. It has been used for the treatment of depression for more than two thousand years. However, the molecular mechanisms remain to be determined. In this study, we evaluated the anti-inflammatory effect and elucidated underlying molecular mechanisms of SSB2 in LPS-induced primary microglia and CUMS-induced mice model of depression. The effects of SSB2 treatment were investigated both in vitro and in vivo. The chronic unpredictable mild stimulation (CUMS) procedure was applied to establish the animal model of depression. Behavioural tests were used to evaluate the depressive-like behaviors in CUMS-exposed mice, including sucrose preference test, open field test, tail suspension test, and forced swimming test. The GPX4 gene of microglia was silenced using shRNA, and inflammatory cytokines were determined by Western Blot and immunofluorescence analysis. Endoplasmic reticulum stress and ferroptosis-related markers were detected by qPCR, flow cytometry and confocal microscopy. SSB2 reversed depressive-like behaviours in CUMS-exposed mice and relieved central neuroinflammation and ameliorated hippocampal neural damage. SSB2 alleviated LPS-induced activation of microglia through the TLR4/NF-\u03baB pathway. LPS-induced ferroptosis, with increased levels of ROS, intracellular Fe2+, mitochondrial membrane potential, lipid peroxidation, GSH, SLC7A11, FTH, GPX4 and Nrf2, and decreased transcription levels of ACSL4 and TFR1, was attenuated with SSB2 treatment in primary microglia cells. GPX4 knockdown activated ferroptosis, induced endoplasmic reticulum (ER) stress, and abrogated the protective effects of SSB2. Further, SSB2 attenuated ER stress, balanced calcium homeostasis, reduced lipid peroxidation and intracellular Fe2+ content by regulating the level of intracellular Ca2+. Our study suggested that SSB2 treatment can inhibit ferroptosis, maintain calcium homeostasis, relieve endoplasmic reticulum stress and attenuate central neuroinflammation. SSB2 exhibited anti-ferroptosis and anti-neuroinflammatory effects through the TLR4/NF-\u03baB pathway in a GPX4-dependent manner.",

Galectin-3 (Gal-3) is one of the scaffold proteins of Galectins. Studies have indicated that Gal-3 plays an important role in the physiological and pathological state of the nervous system. Here we focus on the role of Gal-3 in ICH, especially in neuroinflammation. Injection of autologous blood into the right basal ganglia was used to simulate ICH injury, and the level of Gal-3 in brain was regulated by related means. The changes of Gal-3 were detected by western blot and immunofluorescence, the level of neuroinflammation by immunofluorescence staining and ELISA. Apoptosis and neuron loss were detected by TUNEL staining FJB staining and Nissl staining, and neurological deficits were judged by neurobehavioral tests. The protein level of Gal-3 increased at 24 h after ICH. Downregulation of Gal-3 level can reduce the infiltration of M1-type microglia and peripheral inflammatory cells, thus alleviating post-ICH neuroinflammation, and reducing cell apoptosis and neuron loss in brain tissue. ICH-induced neurological damage was rescued. Meanwhile, the promotion in the expression level of Gal-3 increased neuroinflammatory activation and nerve cell death, aggravating ICH-induced brain injury. This study proves that Gal-3 is involved in neuroinflammation and nerve damage after ICH. Gal-3 expression should not be encouraged early on to prevent neuroinflammation. which provides a new possibility for clinical treatment for ICH patients.",

Growing evidence suggests that the Cyclic GMP-AMP synthase (cGAS)- Stimulator of interferon genes (STING) pathway, a component of innate immunity, is closely associated with microglia activation, neuroinflammation, and regulated cell death in ischemic stroke. However, the mechanisms underlying this pathway remain inadequately understood. This article comprehensively reviews the existing literature on the cGAS-STING pathway and its multifaceted relationship with ischemic stroke. Initially, it examines how various risk factors and pre-disease mechanisms such as metabolic dysfunction and senescence (e.g., hypertension, hyperglycemia, hyperlipidemia) affect the cGAS-STING pathway in relation to ischemic stroke. Subsequently, we explore in depth the potential pathophysiological relationship between this pathway and oxidative stress, endoplasmic reticulum stress, neuroinflammation as well as regulated cell death including ferroptosis and PANoptosis following cerebral ischemia injury. Finally, it suggests that intervention targeting the cGAS-STING pathway may serve as promising therapeutic strategies for addressing neuroinflammation associated with ischemic stroke. Taken together, this review concludes that targeting the microglia cGAS-STING pathway may shed light on the exploration of new therapeutic strategies against ischemic stroke.",

Since neuroinflammation could occur in response to damage-associated molecular patterns (DAMPs), ZBP1 might be involved in neuroinflammation after stroke. However, the spatiotemporal expression profile of ZBP1 in the post-stroke brain remains to be elucidated. The aim of this study is to demonstrate the spatiotemporal expression patterns of ZBP1 in the post-stroke brain using a mouse photothrombotic stroke model. Real-time PCR assays showed that ZBP1 is induced on days 3-14 post stroke. ZBP1 immunoreactivity was observed in Iba1-positive microglia/macrophages in peri-infarct regions by immunohistochemistry. ZBP1-positive cells were spread in layers surrounding the infarct core by 7-14 days post stroke. Interestingly, ZBP1 immunoreactivity was also detected in CD206-positive border-associated macrophages (BAMs) in the meninges. Furthermore, ZBP1-expressing cells were positive for antibodies against inflammatory mediators such as Toll-like receptor 4 (TLR4), Toll/IL-1R domain-containing adaptor-inducing IFN-\u03b2 (TRIF), and receptor-interacting serine/threonine-protein kinase 1 (RIPK1). Morphological analysis with confocal microscopy showed that the co-localization signals of ZBP1 and its adaptor, TRIF, are increased by glucose oxidase (GOx) treatment, which has been reported to induce mitochondrial DNA (mtDNA) release. These results suggest that ZBP1 is induced in peri-infarct microglia/macrophages and may be involved in DAMPs-mediated neuroinflammation involving mtDNA in the post-infarct brain.",

IS can lead to neuronal cell death and release factors such as damage-related molecular patterns, stimulating the immune system to release inflammatory mediators, thereby resulting in inflammation and exacerbating brain damage. Currently, there are a limited number of treatment methods for IS, which is a fact necessitating the discovery of new treatment targets. For this review, current research on inflammation and cell death in ischemic stroke was summarized. The complex roles and pathways of the principal immune cells (microglia, astrocyte, neutrophils, T lymphocytes, and monocytes/macrophage) in the immune system after IS in inflammation are discussed. The mechanisms of immune cell interactions and the cytokines involved in these interactions are summarized. Moreover, the cell death mechanisms (pyroptosis, apoptosis, necroptosis, PANoptosis, and ferroptosis) and pathways after IS are explored. Finally, a summary is provided of the mechanism of action of natural pharmacological active ingredients in the treatment of IS. Despite significant recent progress in research on IS, there remain many challenges that need to be overcome.",

Here, cell counting kit-8 method assayed the viability of BV2 microglial cells treated by ascending concentrations of emodin. In emodin-pretreated BV2 microglial cells challenged with morphine with or without transfection of toll-like receptor 4 (TLR4) overexpression plasmids, transwell assay measured cell migration. Immunofluorescence staining and western blot detected the expression of microglial markers. Inflammatory levels were subjected to ELISA and western blot. BODIPY 581/591 C11 assay estimated lipid reactive oxygen species activity. Iron assay kit examined total iron content. Western blot tested the expression of ferroptosis- and TLR4/nuclear factor-kappaB (NF-\u03baB)/NOD-like receptor 3 (NLRP3) pathway-associated proteins. Molecular docking predicted the binding affinity of emodin to TLR4. Emodin was noted to obstruct the migration, activation, inflammatory response, and ferroptosis of BV2 microglial cells induced by morphine. In addition, emodin had a high binding affinity with TLR4 and inactivated TLR4/NF-\u03baB/NLRP3 pathway in morphine-challenged BV2 microglial cells. Upregulation of TLR4 partially countervailed the protective role of emodin against morphine-elicited BV2 microglial cell migration, activation, inflammation, and ferroptosis. Accordingly, emodin might target TLR4 and act as an inactivator of TLR4/NF-\u03baB/NLRP3 pathway, thus inhibiting BV2 microglial activation and inflammation to mitigate morphine tolerance.",

The present study investigated the anti-neuroinflammatory properties of nobiletin (Nob) derivative, 5-acetoxy-6,7,8,3',4'-pentamethoxyflavone (5-Ac-Nob), in lipopolysaccharide (LPS)-activated BV2 microglia. By using the MTT assay, Griess method, flow cytometry, and enzyme-linked immunosorbent assay (ELISA), we determined the cell viability, the levels of nitric oxide (NO), reactive oxygen species (ROS), and pro-inflammatory factors (interleukin 1 beta; IL-1\u03b2, interleukin 6; IL-6, tumor necrosis factor alpha; TNF-\u03b1 and prostaglandin E2; PGE2) in LPS-stimulated BV2 microglia. Toll-like receptor 4 (TLR4)-mediated myeloid differentiation primary response gene 88 (MyD88)/nuclear factor-kappa B (NF-\u03baB), mitogen-activated protein kinase (MAPK) signaling pathway and signal transducer and activator of transcription 3 (STAT3) were measured by western blotting. Analysis of NO generation and mRNA of pro-inflammatory cytokines was confirmed in the zebrafish model. 5-Ac-Nob reduced cell death, the levels of NO, ROS, inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), and pro-inflammatory factors in LPS-activated BV-2 microglial cells. TLR4-mediated MyD88/NF-\u03baB and MAPK pathway (p38, ERK and JNK) after exposure to 5-Ac-Nob was also suppressed. Moreover, 5-Ac-Nob inhibited phosphorylated STAT3 proteins expression in LPS-induced BV-2 microglial cells. Furthermore, we confirmed that 5-Ac-Nob decreased LPS-induced NO generation and mRNA of pro-inflammatory cytokines in the zebrafish model. Our findings suggest that 5-Ac-Nob represses neuroinflammatory responses by inhibiting TLR4-mediated signaling pathway and STAT3. As a result of these findings, 5-Ac-Nob has potential as an anti-inflammatory agent against microglia-mediated neuroinflammatory disorders.",

They are closely associated with poor prognosis and low quality of life. The State Food and Drug Administration of China has approved DL-3-n-butylphthalide (NBP) as a treatment for ischemic stroke (IS). Clinical research has shown that NBP alleviates anxiety and depressive symptoms in patients with IS. Therefore, this study explored the role and molecular mechanisms of NBP in cases of post-stroke emotional disorders using network pharmacology and experimental validation. The results showed that NBP treatment significantly increased the percentage of time spent in the center of the middle cerebral artery occlusion (MCAO) rats in the open field test and the percentage of sucrose consumption in the sucrose preference test. Network pharmacology results suggest that NBP may regulate neuroinflammation and cell death. Further experiments revealed that NBP inhibited the toll-like receptor 4/nuclear factor kappa B signaling pathway, decreased the level of pro-inflammatory cytokines, including tumor necrosis factor-\u03b1, interleukin-1\u03b2, and interleukin-6, and M1-type microglia markers (CD68, inducible nitric oxide synthase), and reduced the expression of PANoptosis-related molecules including caspase-1, caspase-3, caspase-8, gasdermin D, and mixed lineage kinase domain-like protein in the hippocampus of the MACO rats. These findings demonstrate that the mechanisms through which NBP ameliorates post-stroke emotional disorders in rats are associated with inhibiting neuroinflammation and PANoptosis, providing a new strategy and experimental basis for treating post-stroke emotional disorders.",

In addition, numerous physiological signaling factors act as agonists or antagonists of TLR4 expressed by non-immune cells. Recently, TLR4 was found to be highly expressed in cerebellar Purkinje neurons (PNs) and involved in the maintenance of motor coordination through non-immune pathways, but the precise mechanisms remain unclear. Here we report that mice with PN specific TLR4 deletion (TLR4PKO mice) exhibited motor impairments consistent with cerebellar ataxia, reduced PN dendritic arborization and spine density, fewer parallel fiber (PF) - PN and climbing fiber (CF) - PN synapses, reduced BK channel expression, and impaired BK-mediated after-hyperpolarization, collectively leading to abnormal PN firing. Moreover, the impaired PN firing in TLR4PKO mice could be rescued with BK channel opener. The PNs of TLR4PKO mice also exhibited abnormal mitochondrial structure, disrupted mitochondrial endoplasmic reticulum tethering, and reduced cytosolic calcium, changes that may underly abnormal PN firing and ultimately drive ataxia. These results identify a previously unknown role for TLR4 in regulating PN firing and maintaining cerebellar function.",

Formononetin (FMN) has been observed to inhibit BV2 microglial cell activation and alleviate ensuing neuroinflammatory reactions. Despite extensive research, the precise underlying mechanism remains unclear. To investigate the neuroinflammatory response following FMN-mediated inhibition of BV2 microglial activation, we employed an in vitro oxygen-glucose deprivation/reperfusion (OGD/R) model. BV2 microglial cells were categorized into four groups: control, FMN, OGD/R, and OGD/R+FMN. Cell viability was assessed using the CCK-8 assay, while flow cytometry assessed M1 and M2 cell populations within BV2 cells. Immunofluorescence was utilized to detect the expression levels of apoptosis-inducing factor (AIF), p53, Toll-like receptor 4 (TLR4), and NF-\u03baB p65. Western blotting (WB) was conducted to quantify p65/p-p65, I\u03baB-\u03b1/p-I\u03baB-\u03b1, and TLR4 protein levels in each group. Additionally, ELISA was employed to measure IL-1\u03b2 and TNF-\u03b1 levels in cell supernatants from each group. The results revealed a significant increase in the proportion of iNOS/CD206-positive M1/M2 cells in the OGD/R group compared to the control group (p\u00a0<\u00a00.05). There was also a notable increase in nuclear translocation of NF-\u03baB p65 and elevated expression of inflammatory factors IL-1\u03b2 and TNF-\u03b1 in cell supernatants. Moreover, levels of p-p65, p-I\u03baB-\u03b1, and TLR4 proteins were significantly elevated in the OGD/R group (p\u00a0<\u00a00.05). However, the addition of FMN reversed these effects. Specifically, FMN administration notably attenuated cell death and inflammation in BV2 microglia induced by OGD/R through modulation of the TLR4/NF-\u03baB signaling pathway.These findings suggest that FMN may serve as a potential therapeutic agent against neuroinflammation associated with ischemic stroke by targeting microglial activation pathways.",

Microglia activation is accompanied by the formation and chronic expression of TLR4 inflammarafts, defined as enlarged and cholesterol-rich lipid rafts serving as an assembly platform for TLR4 dimers and complexes of other inflammatory receptors. The secreted apoA-I binding protein (APOA1BP or AIBP) binds TLR4 and selectively targets cholesterol depletion machinery to TLR4 inflammaraft-expressing inflammatory, but not homeostatic microglia. Here we demonstrated that amyloid-beta (A\u03b2) induced formation of TLR4 inflammarafts in microglia in vitro and in the brain of APP/PS1 mice. Mitochondria in Apoa1bp-/- APP/PS1 microglia were hyperbranched and cupped, which was accompanied by increased reactive oxygen species and the dilated endoplasmic reticulum. The size and number of A\u03b2 plaques and neuronal cell death were significantly increased, and the animal survival was decreased in Apoa1bp-/-APP/PS1 compared to APP/PS1 female mice. These results suggest that AIBP exerts control of TLR4 inflammarafts and mitochondrial dynamics in microglia and plays a protective role in Alzheimer's disease associated oxidative stress and neurodegeneration.",

It typically impairs memory consolidation and synaptic plasticity, potentially through neuroinflammatory mechanisms and adenosinergic signalling. It is still unclear whether the adenosine A1 receptor (A1R) modulates SD-induced neurological deficits in the hippocampus. This study aims to evaluate the effects of SD on fear extinction memory recall and emotional behaviour in male Sprague Dawley rats; to investigate the role of A1R antagonism by the administration of 8-cyclopentyltheophylline (8-CPT), an A1R antagonist during 48-hour SD in mitigating neuroinflammation and synaptic plasticity deficits induced by SD; and to assess changes in hippocampal neurogenesis, neuronal cell death, and sleep architecture in response to A1R antagonism during SD. A total of 39 animals were used in the study, and they were divided into three experimental groups: 1) cage control (CC; n = 13); 2) SD for 48 hours (SD; n = 13); 3) SD for 48 hours+ 8-CPT (20 mg/kg/day in 20% DMSO divided into two doses, morning and evening, i.p.; n = 13). 'n' refers to the sample size/number of animals in each group. Rats were subjected to SD after cued fear extinction training for 48 hours followed by fear extinction memory recall test, anxious-depressive-like behaviours by open field test (OFT), sucrose preference test, and forced swim test (FST). Levels of adenosine in the hippocampus were quantified by high-performance liquid chromatography. Protein levels of interleukin-6 (IL-6) and IL-10 were quantified by enzyme-linked immunosorbent assay (ELISA). Expression levels of proteins and genes of interest were analysed using immunohistochemistry and real-time polymerase chain reaction (RT-PCR), respectively. Sleep architecture was assessed by recording electroencephalography (EEG), electromyography, and electrooculography from rats. Administration of CPT during SD reversed extinction recall impairments (p = 0.01), improved line crossings in OFT, sucrose preference (p < 0.01), and reduced immobility during the FST (p < 0.01). Immunohistochemical analysis of DG, CA3, and CA1 regions of the hippocampus revealed a significant upregulation of A1R expression in the SD and SD+CPT groups (p < 0.001, n = 5). Expression of post-synaptic density protein (PSD-95) and synaptophysin increased and a marked reduction in the Toll-like receptor-4\u00a0(TLR-4) expression in activated microglia in the SD+CPT group. 8-CPT partially restored SD-induced decline in serotonin and brain-derived neurotrophic factor. SD-induced neuronal apoptosis through caspase-3 and the P-p38 mitogen-activated protein kinase pathway was partially reversed by 8-CPT. RT-PCR results showed that A1R antagonism attenuated gene expression of pro-inflammatory cytokines (IL-1\u03b2, TNF\u03b1, p-NF\u03baB s536, and IL-6) and increased anti-inflammatory cytokines (IL-1ra, IL-4, IL-10, IL-11, and IL-13) during SD. EEG recordings revealed that A1R antagonism increased REM sleep without affecting non-REM sleep during SD, leaving rebound sleep unaffected.\u00a0 Conclusion: These findings highlight the role of A1R antagonism in restoring fear extinction memory recall, synaptic plasticity, adult neurogenesis, neuronal cell death, and attenuating neuroinflammation during SD, paving the way for the further exploration of its therapeutic potential in sleep-related cognitive deficits.",

These diseases involve complex pathophysiological mechanisms, including inflammatory responses, oxidative stress, and ferroptosis. Compounds derived from deep-sea fungi exhibit low toxicity and potent neuroprotective effects, offering a promising source for drug development. In this study, we isolated 44 natural products from deep-sea-derived fungi and identified isobisvertinol (17) as a compound with anti-inflammatory and ferroptosis-inhibiting effects. Using LPS-induced microglial inflammation and RSL3-induced neuronal ferroptosis models, we found that 17 targets TLR4 to provide neuroprotection. Molecular docking studies revealed that 17 inhibits TLR4 activation by occupying the hydrophobic pocket at the TLR4-MD2 binding site. Additionally, 17 suppresses TLR4, reducing p38 MAPK phosphorylation, and inhibits ferroptosis by decreasing lipid peroxidation and modulating mitochondrial membrane potential. Metabolomic analysis showed that 17 rescues alterations in multiple metabolic pathways induced by RSL3 and increases levels of antioxidant metabolites, including glutamine, glutamate, and glutathione. In summary, our results indicate that isobisvertinol (17) targets TLR4 in neural cells to reduce inflammation and inhibit p38 MAPK phosphorylation, while regulating metabolic pathways, mainly GSH synthesis, to provide antioxidant effects and prevent ferroptosis in neurons.",

PCD, regulated through various forms such as apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagic cell death, is essential for maintaining tissue stability and eliminating abnormal cells. Dysregulation of PCD is associated with numerous diseases, including cancer and neurodegenerative disorders. Recent studies have revealed extensive crosstalk and coordination among classical cell death pathways, leading to the identification of a novel programmed cell death mode termed PANoptosis. PANoptosis involves the dynamic assembly of the PANoptosome complex, which simultaneously activates apoptosis, pyroptosis, and necroptosis pathways in response to pathogen infection or tissue damage. In neurological diseases, PANoptosis exhibits dual roles: it can eliminate pathogen-infected cells but may also exacerbate neuroinflammation and neuronal death, contributing to the progression of neurodegenerative disorders. This review critically evaluates the molecular mechanisms of PANoptosis, its dual roles in neurological diseases (eg, Alzheimer's disease, Parkinson's disease, stroke, and glioma), and potential therapeutic strategies targeting PANoptosis, including small-molecule inhibitors, genome editing, and delivery technologies. By addressing conflicting evidence and outstanding questions, this review aims to provide a comprehensive framework for future research and clinical applications. Future research should focus on elucidating the molecular regulatory networks of PANoptosis, developing specific inhibitors, and advancing clinical applications to provide novel insights into the precise treatment of neurological diseases.",

M1-like microglia are key players in the inflammatory response after injury. We hypothesize that the depletion of this microglia subtype would shift the M2/M1-like microglia balance toward a more pro-resolutive environment, favorable to SCI repair. The colony-stimulating factor 1 receptor (CSF1R) antagonist PLX5622 has been used to deplete microglia in the central nervous system. Although PLX5622 can freely cross the blood-brain barrier after systemic administration, it requires solubilization in DMSO, an organic solvent toxic for the central nervous system, while the low drug concentration that accumulates at the SCI hampers its effectiveness. Systemic administration of PLX5622 can induce side effects due to off-target accumulation. In this study, for the first time, we specifically depleted M1-like microglia by designing polymeric nanoparticles loaded with PLX5622 (PLX NPs) to locally treat spinal cord contusion. PLX NP was prepared using a microfluidic-assisted approach showing high encapsulation efficiency (approx. 84\u00a0%), nanosized dimensions (100\u00a0nm), and batch-to-batch reproducibility. PLX NP displayed selective activity in depleting M1-like microglial cells in both resting and lipopolysaccharide (LPS)-activated mixed microglial cell models while preserving non-targeted glial cells. Furthermore, locally administered PLX NP downregulated proinflammatory cytokines (e.g., TNF-\u03b1, IL-6, and IL-1\u03b2), increasing the M2/M1-like microglia ratio, thus reducing inflammation in a SCI contusion model. Our data support the hypothesis that local treatment with PLX NP, a formulation with a high translational value, reduces neuroinflammation and shifts the microglia population toward a pro-resolutive phenotype, with potential applications in SCI and central nervous system inflammatory diseases.",

Although the precise etiology remains unclear, multiple pathological mechanisms contribute to disease progression, including mitochondrial dysfunction, protein aggregation, calcium excitotoxicity, endoplasmic reticulum (ER) stress, oxidative stress, immune system activation, and neuroinflammation. Among these, the immune response plays a crucial role in disease pathogenesis, acting as a defense mechanism against damage-associated molecular patterns (DAMPs), pathogen-associated molecular patterns (PAMPs), and toxic molecular species. Chronic immune activation, particularly of microglia, is a defining feature of neuroinflammation, which involves both innate and adaptive immune responses. In the central nervous system (CNS), microglia-mediated neuroinflammation leads to the release of proinflammatory cytokines, exacerbating neuronal damage. Necroptosis, a regulated form of programmed cell death, has been implicated in neuroinflammatory disorders, including PD. Persistent microglial activation in response to aggregated proteins stimulates various microglial receptors, which includes Toll-like receptor 4 (TLR4), that play a pivotal role in necroptosis activation via the myeloid differentiating primary response gene 88 (MYD88)-independent pathway. This review explores how immune system-mediated receptor activation triggers cell death pathways, with a focus on TLR-induced necroptosis in PD. In addition, we also discuss various downstream molecular mechanisms linking TLR signaling to necroptosis and discuss the potential of TLRs as therapeutic targets, offering insights for developing neuroprotective strategies in neurodegenerative diseases (NDDS).",

Our previous study also showed that Gal-3 could aggravate ICH-induced brain injury through increasing neuroinflammatory activation and nerve cell death. In this study, we focus on the role of Gal-3 in nerve cell death after ICH. An ICH mice model and an in vitro co-stimulation model were established to study Gal-3's effect on neuron cell death via toll-like receptor 4 (TLR4)/nuclear factor kappa-B (NF-\u03baB) pathway. Western blot and immunofluorescence (IF) staining were applied for neuron apoptosis evaluation. Enzyme-linked immunosorbent assay (ELISA) was used to measure the production of neuroinflammation factors. Gal-3 expression in microglia was increased and positively correlated with the severity of neurological impairment after ICH. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and NeuN (or MAP2) double staining assay results revealed that the increasing of neuron cell apoptosis after Gal-3 treatment both in in vivo and in vitro co-stimulation experiments could be reversed by treatment with Gal-3 inhibitor MCP, TLR4 inhibitor TAK-242, NF-\u03baB inhibitor PDTC, or TNF-\u03b1 inhibitor C87 effectively. ELISA results revealed the same trends of TNF-\u03b1 release changes from microglia after Gal-3 or inhibitor treatment both in vivo and in vitro. WB results confirmed the Gal-3's role on apoptosis by the expression level of proteins such as FADD, Apaf-1, Bax, Cytochrome C, Caspase-8, and cleaved-Caspase-3 in neuron cells.

This study investigates to explore that RIPK3 regulates microglial polarization through the TLR4/MyD88 signaling pathway in neuropathic pain. By using a chronic constriction injury (CCI) model in mice, we found that peripheral nerve injury promoted M1 polarization and activated the TLR4/MyD88 pathway in spinal cord; in BV-2 microglia models, TNF-\u03b1/Z-VAD co-induction triggered M1 polarization through TLR4/MyD88 pathway, TLR4 antagonists suppressed these effects both in vivo and in vitro. Administration of GSK'872 (RIPK3 inhibitor) inhibited TLR4/MyD88 pathway, reduced microglial M1 polarization, promoted microglial M2 polarization and alleviated CCI-induced hyperalgesia. These findings suggest that necroptosis is a key cellular mechanism in peripheral injury-induced neuropathic pain and that RIPK3 regulates microglial polarization via the TLR4/MyD88 pathway, providing a new target for neuropathic pain treatment and clinical prevention.",

Given the lack of evidence-based methods for diagnosing and assessing fibromyalgia, it ranks among the most difficult chronic pain conditions to treat. Programmed cell death ligand 1 (PD-L1) can inhibit acute and chronic pain transmission by inhibiting neuronal ion channels. Here, we aimed to explore the analgesic efficacy and mechanism of PD-L1/PD1 in an intermittent cold stress-induced fibromyalgia pain mouse model. Von Frey and Hargreaves tests were performed, showing that the mouse model exhibited mechanical (day 4: 2.08 \u00b1 0.13 g, n = 9) and thermal hyperalgesia (day 4: 3.93 \u00b1 0.45 s, n = 9). Electroacupuncture (EA) or intraventricular PD-L1 injection effectively alleviated the nociceptive response and led to low PD-1 levels in the mouse dorsal root ganglia, spinal cord, thalamus, somatosensory cortex, and cerebellum, as measured through Western blots. In contrast, the pain-related kinase levels increased after fibromyalgia induction; these effects were reversed by EA and PD-L1 via the inhibition of microglia/astrocytes and Toll-like receptor 4. Our results show that EA can treat fibromyalgia pain in mice through effects on the PD-L1/PD1 pathway, indicating its potential as a therapeutic target in fibromyalgia.",

This study aimed to investigate the role of neuronal Toll-like receptor 4 (TLR4) in promoting ferroptosis, an iron-dependent cell death pathway, during experimental autoimmune encephalomyelitis (EAE). We leveraged a MOG35-55-induced EAE mouse model (n\u00a0=\u00a010 per group) alongside in vitro LPS-stimulated SH-SY5Y mono- and co-culture systems (n\u00a0=\u00a03 biological replicates) to interrogate the crosstalk between TLR4 signaling and ferroptosis. This link was comprehensively evaluated via biochemical assays, Western blotting, RT-qPCR, co-immunoprecipitation, immunofluorescence analyses, and transmission electron microscopy. Furthermore, we mechanistically dissected the underlying signaling cascades using siRNA-mediated gene silencing and co-immunoprecipitation. Both in vivo and in vitro models recapitulated classical ferroptosis features, including NCOA4-mediated ferritinophagy, lipid peroxidation, and iron overload. Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism. Observations indicate that the TLR4 signaling contributes to ferroptosis even within the complex inflammatory microenvironment of microglia-neuron co-cultures. In EAE mice, pharmacological blockade of ferroptosis via Liproxstatin-1 appeared to ameliorate clinical severity, associated with restored neuronal GPX4 expression in the brain and spinal cord, and concomitantly suppressed lipid peroxidation. This study proposes a specific TLR4-mtDNA-cGAS-STING-NCOA4 signaling cascade that may facilitate neuronal ferroptosis in EAE mice. These findings suggest a novel mechanism of neuronal injury in MS and underscore that targeting this intrinsic neuronal pathway could represent a promising therapeutic strategy to ameliorate progressive neurodegeneration.",

Sinensetin (SIN), a polymethoxylated flavone derived from citrus fruits, possesses potent anti-inflammatory and antioxidant properties. However, its therapeutic efficacy and underlying mechanisms in PSD have not been explored. To investigate this, a mouse model of PSD was established by combining photothrombotic stroke with low-dose lipopolysaccharide (LPS) administration. Mice were treated with SIN (25 and 50\u00a0mg/kg) for 14 days. Depressive-like behaviors were assessed using the sucrose preference test (SPT), tail suspension test (TST), and forced swimming test (FST). Crucially, protein-level validation was performed using quantitative immunofluorescence (for glial activation) and ELISA (for serum cytokines and pathway markers), complemented by qPCR and molecular docking/dynamics (MD) simulations. SIN treatment significantly alleviated depressive-like behaviors and restored cerebral blood flow in PSD mice. Quantitative immunofluorescence and ELISA analyses revealed that SIN effectively suppressed the hyperactivation of microglia (IBA1) and astrocytes (GFAP) in the hippocampus and reduced serum concentrations of pro-inflammatory cytokines (TNF-\u03b1, IL-6, IL-1\u03b2). Mechanistically, SIN inhibited the TLR4/NF-\u03baB signaling pathway by suppressing NF-\u03baB nuclear translocation and concurrently activated the NRF2/GPX4 antioxidant axis, thereby mitigating lipid peroxidation and neuronal ferroptosis. Additionally, molecular docking and MD simulations predicted energetically favorable interactions between SIN and key targets (e.g., TLR4, KEAP1), providing supportive evidence for its multi-target mechanism. Our findings demonstrate that SIN exerts neuroprotective effects in PSD by dually modulating TLR4/NF-\u03baB-mediated neuroinflammation and NRF2/GPX4-dependent ferroptosis. These results highlight SIN as a promising natural therapeutic candidate for the treatment of depression following stroke.",

Despite advancements in anti-VEGF treatments, the mechanisms driving pathological vitreoretinal neovascularization remain unclear. I examined the role of Toll-like receptor 4 (TLR4) in modulating inflammatory cytokines, angiogenesis, and neuronal cell protection in a mouse model of oxygen-induced retinopathy (OIR). C57BL/6J TLR4-/- mice were subjected to OIR by exposure to 75% oxygen from postnatal days 7 to 12 (P7 to P12) following approved protocols. I used immunohistochemistry to assess TLR4 expression at P19, real-time quantitative PCR for proinflammatory cytokines at P19, ex vivo fluorescent vascular imaging to evaluate retinal vascular changes at P19, and retinal neuronal cells death evaluated by whole-mounted retina stained with cresyl violet at P47. Statistical significance was determined using one-way ANOVA (p\u202f<\u202f0.05). Immunofluorescence demonstrated TLR4 expression in microglia in OIR retinas of wild-type mice but not in controls. Real-time PCR revealed significant upregulation of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP1) in OIR retinas, which was mitigated in TLR4-/- mice. Retinal angiogenesis significantly increased in wild-type OIR mice, whereas TLR4 knockdown inhibited these changes. Additionally, OIR caused approximately 30% neuronal cell death in the retinal ganglion cell layer, which was largely prevented in the TLR4-/- mice. These findings underscore TLR4's pivotal role in the regulation of inflammatory responses and angiogenesis in ROP. Targeting TLR4 may represent a novel therapeutic approach to preserve retinal integrity and improve visual outcomes in at-risk populations, particularly in premature infants.",

This study examined the efficacy of EPA ingestion for reducing chronic pain and depression comorbidity (CPDC) in a mouse model established using intermittent cold stress. Our results showed that oral EPA could alleviate mechanical and thermal hyperalgesia in CPDC mice. The preventive effect of EPA on depressive symptoms in CPDC mice was further confirmed. Western blot and immunofluorescence staining revealed that EPA can inhibit the enhanced neuroinflammatory signaling concomitant with increased astrocyte and microglia activation and elevated levels of inflammatory signaling factors high-mobility group box 1 (HMGB1) and S100B in the CPDC mice. Alternatively, oral EPA can increase the attenuated expression of the pain-inhibiting programmed cell death protein 1 (PD-1) receptor. EPA intake can further alleviate inflammation-associated toll-like receptor 4 (TLR4) and downstream signaling molecules myeloid differentiation primary response 88 (MyD88), TNF receptor associated factor 6 (TRAF6), and activated (phosphorylated) nuclear factor kappa-light-chain-enhancer of activated B cells (pNF\u03baB) in CPDC mouse brain. A similar response also observed in transient receptor potential vanilloid 1 gene knockout mice. This demonstration that oral EPA can prevent CPDC by inhibiting neuroinflammatory pathways could facilitate improved treatment strategies for CPDC.",

Ferroptosis, an iron-dependent and lipid peroxidation-associated form of regulated cell death, has recently been identified as a key contributor to neuronal vulnerability. Emerging evidence demonstrates that purified natural monomer compounds derived from medicinal plants exert potent neuroprotective effects by targeting ferroptosis and neuroinflammatory pathways. Representative agents such as curcumin, baicalin, resveratrol, and ginsenoside Rg1 activate nuclear factor E2-related factor-2 and glutathione peroxidase 4 signaling to preserve redox balance, while suppressing microglia-mediated inflammation through inhibition of toll-like receptor 4 pathways. This review highlights the interplay between ferroptosis and neuroinflammation in NDDs, summarizes the regulatory effects of bioactive herbal monomer compounds, and discusses recent advances in multi-omics profiling, nano-delivery strategies, and translational research. By modulating the ferroptosis-neuroinflammation axis, these compounds may represent promising therapeutic candidates for NDDs.",

Therefore, there is an urgent need for new therapeutic targets and strategies to address this challenge. To construct a mouse model of SCI, an aneurysm clip was used in\u00a0vivo to clamp the abdominal aorta below the left renal artery in C57BL/6J mice. After 60\u2009min, the aneurysm clip was removed to restore blood flow. In\u00a0vitro, primary neuronal cells were subjected to OGD/R to mimic the conditions of SCI. Cell viability was assessed using the CCK-8 assay, and the levels of neuronal death, autophagy, and ferroptosis were determined using a combination of WB, IF, and transmission electron microscopy. IP/MS and Co-IP techniques were employed for the identification and validation of proteins interacting with USP5. Neurons exhibit significant ferroptosis in the SCI mice. USP5 is markedly upregulated in SCI neurons and mediates neural ferroptosis. In\u00a0vitro experiments demonstrate that overexpression of USP5 promotes neuronal ferroptosis, whereas knockout of USP5 significantly reduces it, with consistent results observed in\u00a0vivo. Notably, the upregulation of USP5 expression markedly increases the accumulation of autophagosomes and autophagic flux in neurons, which may represent a potential mechanism by which USP5 mediates neuronal ferroptosis. Further investigations utilizing IP/MS and Co-IP confirmed the interaction between USP5 and c-MAF. Additionally, Western blot analysis revealed that USP5, through its deubiquitinating enzyme activity, enhances c-MAF protein stability, thereby activating autophagy and subsequently promoting neuronal ferroptosis. In summary, our results indicate a close relationship between ferroptosis and SCI. USP5 regulates c-MAF expression through deubiquitination, thereby activating autophagy-dependent ferroptosis in neurons and mediating the progression of SCI. USP5 may serve as a potential therapeutic target for SCI.",

However, its effect on neurogenic bladder fibrosis following spinal cord injury (SCI) and its association with ferroptosis remain unclear. This study aimed to investigate the therapeutic efficacy of PFD against bladder fibrosis after SCI and to preliminarily analyze its potential link with ferroptosis using a rat SCI model and a Transforming Growth Factor-\u03b21 (TGF-\u03b21)-induced fibrotic model in Simian Virus 40-Transformed Human Urothelial Cells (SV-HUC-1). In SCI rats, PFD treatment significantly improved urodynamic parameters, while markedly reducing collagen deposition, inflammatory infiltration, and the progression of epithelial-mesenchymal transition (EMT) in bladder tissue. In the cellular model, PFD effectively attenuated TGF-\u03b21-induced fibrotic responses. Mechanistically, network pharmacology analysis predicted that PFD could modulate the TGF-\u03b21 signaling and lipid peroxidation pathways. In vivo experiments confirmed that PFD reversed the dysregulation of key ferroptosis-related molecules, and in vitro studies demonstrated that PFD antagonized Erastin-induced ferroptosis, an effect comparable to the ferroptosis inhibitor Ferrostatin-1 (Fer-1). However, in the TGF-\u03b21-induced fibrotic model, inhibition of ferroptosis alone only partially ameliorated the fibrotic phenotype, and its effect was weaker than that of PFD. This study demonstrates that PFD can effectively alleviate bladder fibrosis after SCI, and its therapeutic effect may be associated with the ferroptosis pathway. These findings suggest that PFD likely exerts its anti-fibrotic action through multi-pathway synergy, with ferroptosis inhibition representing an important contributing pathway supported by the current data, providing a new theoretical basis for treating neurogenic bladder fibrosis.",

Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, has emerged as a contributor to HIV-associated neurocognitive disorders. This study aimed to determine whether hydrogen sulfide (H2S) mitigates HIV Tat-induced ferroptosis in microglial cells. BV2 microglial cells were pretreated with sodium hydrosulfide (NaHS; 100\u2009\u03bcM), an H2S donor, followed by exposure to recombinant HIV Tat (100\u2009ng/mL, 48\u2009h). Ferroptotic indices, including cytosolic Fe2+ accumulation, lipid peroxidation, reactive oxygen species (ROS) generation, and cell membrane damage, were assessed using fluorescence-based assays and lactate dehydrogenase (LDH) release. Expression of ferroptosis-related and antioxidant proteins was analyzed by western blotting, and proinflammatory cytokine release was quantified by qPCR. NaHS pretreatment significantly attenuated HIV Tat-induced Fe2+ accumulation, ROS generation, lipid peroxidation, and LDH release. Mechanistically, NaHS suppressed pro-ferroptotic mediators, acyl-CoA synthetase long-chain family member 4 (ACSL4) and 4-hydroxynonenal (4-HNE), while restoring solute carrier family 7-member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4) expression. NaHS also reduced HIV Tat-induced IL1\u03b2, IL6, and TNF\u03b1 secretion. These findings demonstrate that H2S protects HIV Tat-exposed microglia by suppressing ferroptosis and restoring cellular homeostasis. Collectively, these results identify H2S signaling as a promising mechanistic target for further investigation in NeuroHIV-associated neuroinflammation.",

PANoptosis is a newly identified cell death mode that synergistically initiates pyroptosis, apoptosis and necroptosis via activation of PANoptosome. It is closely associated with oxidative stress, neuroinflammation, and secondary injury following TBI and SCI, yet the key pathogenic factors and mechanisms underlying PANoptosis remain incompletely elucidated. Mitochondria, as a central organelle for energy synthesis and oxidative stress, its health and homeostasis are the cornerstone of cell survival and biological function. Emerging evidence suggests that the loss of mitochondrial homeostasis plays a fundamental role in the activation and execution of PANoptosis across various cell types. Here, we review the detailed manifestations of mitochondrial homeostasis imbalance in TBI and SCI, such as impaired biogenesis, abnormal dynamics, mitophagy dysfunction, and mitochondria-derived vesicles. Meanwhile, we systematically analyze the characteristics and pathological effects of PANoptosis cascade following TBI and SCI, with a focus on the regulatory patterns, mechanisms, and potential targets of injured mitochondria driving PANoptosis. In addition, we discuss the advancements and future perspectives of mitochondria-based strategies for modulating PANoptosis in TBI and SCI. Taken together, despite considerable challenges in governing post-traumatic mitochondria homeostasis, its multiple targeting of the upstream PANoptosome and downstream cell death signaling offers a promising approach to improve the outcome of CNS trauma.",

Originally identified as an adhesion molecule induced after nerve injury, NINJ1 is now recognized as a common terminal executor of PMR across multiple forms of lytic cell death, including pyroptosis, necroptosis, and ferroptosis. This function positions NINJ1 as a key link between cell death and inflammatory activation. However, the precise role of NINJ1 in the central nervous system (CNS) remains unclear. This review systematically outlines the molecular structure, expression, activation, and regulation of NINJ1, with a focus on its multifaceted roles in CNS disorders, including multiple sclerosis, ischemic stroke, traumatic brain injury, spinal cord injury, neuropsychiatric disorders and neurodegenerative diseases. We also highlight critical knowledge gaps, particularly regarding cell type-specific functions in the CNS. Finally, we evaluate therapeutic strategies targeting NINJ1 (including monoclonal antibodies, functional peptides, and small-molecule inhibitors)\u00a0and their potential applications in neurological diseases.

Consequently, precise modulation of pathological glial cells and amelioration of the neuronal microenvironment represent a promising therapeutic strategy. Herein, we developed an injectable, self-healing hydrogel system composed of oxidized sodium alginate, carboxymethyl chitosan, and tannic acid (OCT) for the sustained co-delivery of a Quercetin-Manganese complex (QM) and astrocyte-derived extracellular vesicles encapsulating siRNA (AEVs@siRNA). RNA sequencing revealed significant enrichment of the TNF and chemokine signaling pathways in SCI mice, with a notable upregulation of Serpina3n. This gene, predominantly expressed in astrocytes, modulates their reactive polarization. Leveraging the innate tropism of astrocyte-derived extracellular vesicles, we achieved targeted delivery of Serpina3n-targeting siRNA to astrocytes at the lesion site. This approach effectively suppressed the expression of Serpina3n, inhibiting the transition to a neurotoxic A1 phenotype and alleviating neuronal damage. Concurrently, the sustained release of QM NPs potently scavenged reactive oxygen species, significantly mitigating neuronal ferroptosis. Further mechanistic investigations demonstrated that this combinatorial system attenuated neuroinflammation by inhibiting NF-\u03baB p65 signaling to reduce A1 astrocyte activation, and protected neurons by regulating the SLC7A11/GPX4 axis to counteract apoptosis and ferroptosis, both in vitro and in vivo. Consequently, this targeted delivery system represents a promising approach for enhancing therapeutic efficacy and promoting neural repair following SCI.",

At present, the main Western therapeutic drugs for Parkinson's disease include dopamine precursors, dopamine receptor agonists, monoamine oxidase inhibitors (MAO-B), catechol-O-methyltransferase (COMT) inhibitors and anticholinergic drugs. These treatments have limited efficacy and obvious toxic and side effects. In recent years, with the deepening of research on Parkinson's disease, traditional Chinese medicine (TCM) and its active components have played an increasingly important role in clinical treatment. A large number of studies have shown that TCM and its active components exert anti-Parkinsonian effects by inhibiting ferroptosis, regulating autophagy and apoptosis, exerting anti-inflammatory and antioxidant effects, and enhancing neuronal protection. To show that traditional medicine is a promising strategy for the treatment of Parkinson's disease, and to lay a foundation for exploring the specific mechanisms of traditional Chinese medicine in the prevention and treatment of this disease. This study conducted a bibliometric analysis of Chinese and foreign databases to screen the core traditional Chinese medicines currently used clinically for Parkinson's disease, and further analyzed the specific mechanisms of action of the selected core herbs in the treatment of Parkinson's disease. Bibliometric analysis identified core TCM herbs clinically used for Parkinson's disease. The specific mechanisms of these core herbs against Parkinson's disease were clarified at the molecular level, involving inhibition of ferroptosis, regulation of autophagy and apoptosis, anti-inflammatory and antioxidant effects, and enhancement of neuroprotection. This study provides data support for the subsequent research and clinical application of traditional Chinese medicine in Parkinson's disease, and deepens the molecular understanding of the efficacy of traditional Chinese medicine, verifying that traditional medicine is a promising therapeutic strategy for Parkinson's disease.",

Although many therapeutic strategies have been explored to attenuate secondary injury, effective molecularly targeted interventions remain limited. Increasing evidence identifies signal transducer and activator of transcription 3 (STAT3) as a central signaling node in the neurochemical response to SCI. Recent studies indicate that STAT3 exhibits pronounced spatiotemporal and cell-type-specific activation after SCI. Depending on the upstream trigger and cellular compartment involved, STAT3 can amplify or restrain neuroinflammation, shape astrocyte and microglial reactivity, influence mitochondrial bioenergetics and oxidative stress, modulate ferroptosis and apoptosis, and alter the regenerative state of the injured spinal cord. In this review, we frame STAT3 not simply as a downstream effector of the JAK/STAT cascade, but as an integrative regulator of SCI neurochemistry that links cytokine-driven signaling to metabolic stress, glial remodeling, and axonal repair. We emphasize how injury phase, cell type, and subcellular localization influence STAT3-dependent outcomes, discuss emerging therapeutic strategies that converge on STAT3-centered pathways, and outline the key challenges that must be addressed for precise translational targeting.",

Tetramethylpyrazine (TMP), a bioactive compound derived from traditional Chinese medicine, possesses a wide range of pharmacological activities and has demonstrated potential therapeutic effects in the treatment of SCI. Therefore, this article provides a comprehensive review of the mechanisms by which TMP promotes spinal cord repair. This review compiles a large body of in vitro, in vivo, and clinical studies, including a total of 86 publications documenting the effects of TMP on SCI. The results indicate that the mechanisms by which TMP exerts its effects in SCI treatment include promoting nerve regeneration, improving vascular dysfunction, exerting anti-inflammatory effects, inhibiting neuronal apoptosis, reducing oxidative stress, regulating iron metabolism, maintaining ion homeostasis, alleviating pyroptosis, and modulating autophagy. Through these mechanisms, TMP contributes to the restoration of spinal cord morphology, motor function, and electrophysiological parameters in experimental animal models. Clinical reports on the use of TMP injection for SCI are relatively limited, and its clinical efficacy requires further investigation. The combined application of nanotechnology or hydrogels provides an efficient targeted delivery and sustained-release system for TMP in the spinal cord, thereby significantly enhancing its bioavailability. Overall, TMP shows promising potential in SCI treatment and may serve as a valuable adjunctive therapeutic strategy.",

Stem cell-based approaches have emerged as promising strategies due to their neuroprotective and immunomodulatory properties, largely mediated by small extracellular vesicles (sEVs) and their molecular cargo, including miRNAs. In this study, we aimed to evaluate the neuroprotective and anti-apoptotic potential of sEVs derived from SPC-01 and iMR-90 neural stem cell sources using an in vitro rat model of SCI. sEVs were isolated from SPC-01 and iMR-90 culture media and characterized by MADLS and Western blot. Spinal cord slices (SCS) were used as an in vitro SCI model with three groups: control, SCI, and SCI treated with sEVs. Injury was induced at 18-20\u202fdays in vitro, followed by immediate sEV application. After 72\u202fh, tissue samples were collected and analyzed to assess proteins associated with apoptosis, cytoskeletal integrity, and survival signaling pathways. SCI induced cytoskeletal disruption and increased apoptotic markers. sEV treatment attenuated these changes, reducing injury-associated proteins toward baseline levels. Both SPC-01- and iMR-90-derived sEVs showed neuroprotective effects. This was associated with modulation of key pathways, including decreased PTEN, increased STAT3 phosphorylation, and elevated Bcl-xL. Reduced Nogo-A and normalized RhoA levels further indicate attenuation of inhibitory signaling and improved cytoskeletal stability. Overall, sEVs promoted early neuroprotective responses and reduced pathology-associated protein expression in the SCI model. Neural stem cell-derived sEVs promote neuroprotection in vitro by modulating PTEN/STAT3 signaling, reducing apoptosis, and stabilizing cytoskeletal dynamics. Although limited to early injury responses in an in vitro model, these findings support sEVs as a promising cell-free therapeutic strategy for SCI.",

Although lipid transport at endoplasmic reticulum-mitochondria contact sites (ERMCSs) has been implicated in facilitating ferroptosis, the neuron-specific regulatory mechanisms remain elusive. Here, we show that neuronal ferroptosis is characterized by excessive ERMCS formation. Mechanistically, a systematic screening revealed the down-regulation of stearoyl-CoA desaturase 1 (SCD1), a critical enzyme in the synthesis of monounsaturated fatty acids (MUFAs) in neurons, following SCI (in vivo) or erastin treatment (in vitro). We demonstrated that SCD1 deficiency is the driving force behind aberrant ERMCS expansion, leading to increased lipid peroxidation and neuronal ferroptosis. Conversely, SCD1 overexpression could reverse these effects. Furthermore, we identified liver X receptor alpha (LXR\u03b1) as a direct transcriptional activator of SCD1. Pharmacological activation of LXR\u03b1 with T0901317 upregulated SCD1 expression, which in turn restrained ERMCS formation, elevated MUFA levels, and ultimately inhibited neuronal ferroptosis. In murine SCI models, both adeno-associated virus-mediated neuronal SCD1 overexpression and LXR\u03b1 agonist treatment effectively mitigated excessive ERMCS, reduced lesion size, preserved neuronal architecture, and improved functional recovery. Collectively, our study establishes the LXR\u03b1-SCD1 axis as a novel and druggable pathway for reducing neuronal loss and improving functional recovery by modulating ERMCS-dependent lipid exchange dynamics, revealing promising therapeutic targets after central nervous system trauma.",

Ferroptosis, an iron-dependent form of regulated cell death, contributes significantly to this pathology. This study investigates the hypothesis that miR-10a-5p attenuates spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. A spinal cord I/R injury model was established in male Sprague-Dawley male rats via transient aortic occlusion. Intrathecal injections of the ferroptosis inhibitor Liproxstatin-1 (Lip-1), siRNA targeting ACSL4 or TAK1, and miR-10a-5p agomir/antagomir were administered prior to ischemia induction. Neurological function was assessed using Tarlov scores. Histopathological changes were evaluated by H&E, Nissl, and immunofluorescence staining. Mitochondrial ultrastructure was examined by transmission electron microscopy (TEM). Expression levels of ferroptosis-related markers (ACSL4, GPX4, COX2, FTH1), inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and lipid peroxidation products (MDA, 12-HETE, 15-HETE, LPO) were measured using Western blot, qPCR, and ELISA. The targeting relationship between miR-10a-5p and TAK1 was validated by dual-luciferase reporter assay. Spinal cord I/R injury induced significant neurological deficits, ferroptosis (evidenced by increased iron, MDA, ACSL4, and COX2; decreased GPX4 and GSH), lipid peroxidation, and inflammation. Lip-1 treatment ameliorated these changes. Knockdown of ACSL4 or TAK1 similarly inhibited ferroptosis, reduced inflammation, and improved motor function. Spinal cord I/R injury induced significant downregulation of miR-10a-5p. It directly targeted TAK1, as confirmed by luciferase assay. Consequently, miR-10a-5p overexpression suppressed TAK1/ACSL4 axis, mitigated lipid peroxidation and ferroptosis, and reduced pro-inflammatory cytokine levels (TNF-\u03b1 and IL-1\u03b2), leading to improved neurological outcomes. This study demonstrates that miR-10a-5p plays a protective role in spinal cord I/R injury by targeting TAK1, thereby suppressing ACSL4-mediated ferroptosis and neuroinflammation. These findings highlight the potential of the miR-10a-5p/TAK1/ACSL4 axis as a novel therapeutic target for preventing and treating spinal cord I/R injury.",

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy.",

In the central nervous system (CNS), most ferroptosis research has focused on neurons and glial cells, whereas the vulnerability of brain microvascular endothelial cells (BMECs) and its consequences for blood-brain barrier (BBB) integrity remain less clearly defined. Because BMECs form the vascular interface between the circulation and the brain parenchyma, ferroptotic injury in this cell population may represent an immunovascular mechanism through which endothelial redox stress is translated into barrier dysfunction and neuroinflammatory amplification. In this review, we summarize molecular pathways that may promote or restrain BMEC ferroptosis, including iron handling, antioxidant defense mediated by the solute carrier family 7 member 11 (SLC7A11)-glutathione peroxidase 4 (GPX4) axis and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, lipid peroxidation, and junctional remodeling. We then discuss how ferroptosis-associated endothelial injury may contribute to BBB leakage, damage-associated molecular pattern release, innate immune sensing, leukocyte recruitment, glial activation, and self-amplifying inflammatory feedback at the neurovascular interface. We organize the available literature according to the strength and cellular specificity of evidence, separating BMEC-specific findings, BBB-focused in vivo studies, indirect CNS evidence, and mechanistic analogies from non-CNS endothelial systems. Finally, we evaluate disease-specific evidence in ischemic stroke and selected neurodegenerative or inflammatory conditions, together with therapeutic strategies, BMEC-targeting considerations, candidate clinical biomarkers, and translational barriers for modulating endothelial ferroptosis. This review frames endothelial ferroptosis as a promising but incompletely established immunovascular link between BBB dysfunction and neuroinflammation, and highlights the need for BMEC-specific models, human BBB systems, endothelial ferroptosis biomarkers, biomarker-guided monitoring, BMEC-targeted delivery approaches, and careful evaluation of the physiological risks of systemic or prolonged ferroptosis blockade.",

However, their clinical application for SCI remains inconsistent, likely due to variability in therapeutic outcomes. In our laboratory experiments, we observed similar inconsistencies, including instances where the presence of BMSCs compromised the survival of co-cultured neurons subjected to oxidative stress in vitro. The present study was carried out to find answers for such paradoxical effects caused by BMSCs using an in vitro model involving primary cultured neurons and BMSCs. Both neurons and BMSCs were found to upregulate brain-derived neurotrophic factor (BDNF) production under oxidative stress. To simulate BMSC-mediated release, we introduced exogenous mature BDNF (mBDNF) to stressed neurons in cultures, which unexpectedly led to apoptosis. Observations suggest the possibility of mBDNF-p75 neurotrophin receptor (p75NTR) mediated cell death signaling. Notably, administration of a p75NTR inhibitor (LM11A-31, a small molecule) partially alleviated these detrimental effects. Given the growing interest in BMSC-based therapies, these findings underscore concerns regarding the variability of their effects and the potential for unintended neurotoxicity. Addressing these inconsistencies through further studies will be critical to ensuring the safety and efficacy of BMSC applications in clinical settings. In this regard, concomitant inhibition of p75NTR using small molecules such as LM11A-31 may have potential to avoid contradictory effects of BMSC transplantations caused by unpredictable release of excess BDNF in the transplanted site.",

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.",

In this in-silico study, we investigated the potential therapeutic targets and underlying mechanisms of naringenin (NAR) in SCI by integrating network pharmacology, molecular docking, and molecular dynamics (MD) simulation. The intersection of NAR and SCI targets was used to construct a protein-protein interaction network using the STRING database. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and Wiki Pathway enrichment analyses were performed using the DAVID bioinformatics resource. Finally, we used molecular docking and MD simulation to study the binding interactions between NAR and the core targets. The results show that the core targets of NAR for spinal cord injury include estrogen receptor 1, AKT serine/threonine kinase 1, B-cell lymphoma 2, PPARG, MAPK8, mechanistic target of rapamycin, protein kinase cAMP-activated catalytic subunit alpha, and HRas proto-oncogene, GTPase. These targets and associated biological processes provide multiple mechanisms supporting NAR's action. In addition, enrichment analysis indicates that the AMPK, FoxO, and PI3K-Akt-mechanistic target of rapamycin signaling pathways, autophagy, and apoptosis are the main pathways through which NAR acts in SCI. Molecular docking results show that the binding energy between NAR and key proteins ranges from -7.1 to -8.2 kcal/mol, providing a molecular basis for NAR's treatment of SCI. Molecular dynamics simulation results indicate that the AKT serine/threonine kinase 1-NAR and B-cell lymphoma 2-NAR complexes exhibit good stability. In summary, this study systematically predicts the key targets and signaling pathways through which NAR may act in SCI, providing a theoretical basis for future mechanistic and translational research. However, because the findings are based on computational analyses alone, further in vitro and in vivo validation is required.",

This study aims to investigate the regulatory role of anti-HMGB1 antibody in the depressive-like behaviour of D-SCI rats and to explore its underlying mechanisms. A depression model was established in rats 5\u2009weeks after SCI. The expression of HMGB1 and ferroptosis markers (MDA, GSH and iron ion deposition) in the hippocampus were examined in both the sham group and the D-SCI group. Subsequently, D-SCI rats were treated with an anti-HMGB1 antibody, and the depression-like behaviours of each group were assessed using open field and sucrose preference tests. Ferroptosis levels in the hippocampus, as well as the expression of ferroptosis-related proteins (ACSL4, SLC7A11 and GPX4), were also investigated. The co-localization of HMGB1 and NeuN in the rat hippocampus was detected by immunofluorescence double staining. Furthermore, at the cellular level, the effect of the anti-HMGB1 antibody on Erastin-induced ferroptosis in rat hippocampal neurons was analysed. The results indicated that compared to the sham group, the levels of HMGB1 and ferroptosis in the hippocampus of rats in the D-SCI group were significantly elevated. Administering anti-HMGB1 antibody to D-SCI rats could significantly augment their activity distance, movement speed and sucrose preference rate, while also suppressing the ferroptosis level and the expression of ferroptosis-related proteins in the hippocampus. Moreover, HMGB1 and NeuN were co-expressed in the rat hippocampus. The results from primary rat hippocampal neurons indicated that anti-HMGB1 antibody could inhibit erastin-induced ferroptosis in rat hippocampal neurons. Taken together, anti-HMGB1 antibody therapy can ameliorate depressive behaviour in D-SCI rats; the possible mechanism may involve the inhibition of ferroptosis in hippocampal neurons.",

This study aimed to investigate the role of ferroptosis in CA-induced spinal cord injury and to evaluate the neuroprotective effects of edaravone. Asphyxial CA was induced in rats for 5\u202fmin, followed by resuscitation. Edaravone was administered immediately after the return of spontaneous circulation (ROSC). At 24\u202fh post-ROSC, The CA group exhibited significant hindlimb motor deficits and reduced survival rates. Histological analysis revealed selective injury of choline acetyltransferase (ChAT)-positive motor neurons in the lumbar spinal cord, accompanied by mitochondrial shrinkage and membrane rupture, which are characteristic of ferroptosis. Immunofluorescence demonstrated a selective upregulation of the pro-ferroptotic enzyme acyl-CoA synthetase long-chain family member 4 (ACSL4) specifically in ChAT-positive motor neurons, whereas glutathione peroxidase 4 (GPX4) expression remained relatively preserved. Edaravone treatment significantly improved neurological outcomes and survival, attenuated lipid peroxidation (evidenced by decreased malondialdehyde and preserved glutathione levels), and effectively suppressed ACSL4 upregulation in the motor neurons. Furthermore, edaravone mitigated neuroinflammation by reducing astrogliosis and microglial activation. These findings provide the first evidence that ACSL4-mediated ferroptosis is a key driver of acute spinal motor neuron injury following CA. Edaravone exerts potent neuroprotection by targeting this pathway, suggesting its therapeutic potential for ameliorating spinal cord injury in patients with CA.",

Rather than being viewed only as an endpoint of cell death, ferroptosis in microglia is increasingly recognized as a process that links iron dyshomeostasis, lipid peroxidation, oxidative stress, and immune-inflammatory activation, thereby contributing to the sustained amplification of neuroinflammation. In this review, we summarize the molecular mechanisms by which microglial ferroptosis mediates neuroinflammatory responses, with a focus on iron homeostasis disruption, lipid peroxidation and ROS amplification, collapse of the GPX4-dependent antioxidant defense, mitochondrial ROS generation, and inflammasome activation. We further classify related CNS diseases into three categories according to disease course and pathological features: chronic neurodegenerative and demyelinating diseases, acute CNS injuries, and neuropsychiatric or systemic inflammation-related brain dysfunction. Within this framework, we compare the pathological significance of microglial ferroptosis across different disease contexts. We also discuss potential therapeutic strategies targeting iron homeostasis, lipid peroxidation, antioxidant defenses, inflammatory amplification networks, and microglia-specific delivery systems. Finally, we address current challenges in the field, including insufficient cell-type specificity, inconsistent detection criteria, disease-stage heterogeneity, and barriers to clinical translation. This review provides an integrated perspective on the mechanisms by which microglial ferroptosis drives neuroinflammation and highlights its potential relevance for precision intervention in CNS diseases.",

Sb exposure is known to cause pulmonary, cardiovascular, liver and kidney damage, as well as cancer. In addition, data showing neurotoxic effects of Sb have been also obtained recently. Therefore, the objective of the present review was to discuss existing epidemiological findings linking Sb exposure to brain diseases and the underlying molecular mechanisms of Sb neurotoxicity. Laboratory findings revealed neurotoxic effects of high-dose Sb exposure. Specifically, in vitro and in vivo studies show that Sb induces neuronal apoptosis through induction of oxidative stress, altered Akt/mTOR and Wnt/\u03b2-catenin signaling, and potentially increased Ca2\u202f+ flux. Activation of ferroptosis due to reactive oxygen species (ROS) overproduction, autophagic GPX4 degradation, and NCOA4-mediated ferritinophagy also appear to mediate Sb neurotoxicity. Other mechanisms linked to adverse effects of Sb in brain include altered neurotransmitter metabolism, neuroinflammation, as well as impaired gut-brain axis and neurogenesis. Epidemiological findings show also that Sb exposure, both in single metal and multiple metal exposure models, is associated with increased risk of depression, sleep disorders, anxiety, cognitive dysfunction, and neurodevelopmental disorders like autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD), although controversial data exist. Evidence showing that maternal Sb exposure is also associated with adverse neurodevelopmental outcome in children also exists. While the precise role of Sb exposure in development of neurological diseases has yet to be established due to limited data, a complex of epidemiological and laboratory findings show that Sb should be considered a potential environmental neurotoxicant.",

Current therapeutic options remain largely palliative and fail to reverse the underlying neurogenic pathology. This study employed mild photothermal therapy (MPTT) to treat SSCI-induced NB in rats and systematically investigated its efficacy and mechanisms. Results showed that MPTT effectively improved bladder morphology and urodynamic parameters, with more significant effects observed in early intervention. Mechanistically, MPTT inhibited bladder fibrosis, alleviated chronic inflammation, restored the balance between cell proliferation and apoptosis, promoted functional angiogenesis, and repaired structural damage and function of bladder nerve fibers. MPTT ameliorates SSCI-NB function through multi-target effects, and its time-dependent therapeutic efficacy suggests the necessity of early and repeated interventions, providing experimental and theoretical evidence for new NB treatment strategies.",

Here, a cascade-responsive Zn2+-centered nanoassembly (Zn-PC/PA@Gel) is constructed through stepwise coordination among Zn2+, procyanidin (PC), and polyarginine (PA) to form a core-shell architecture with a Zn2+-procyanidin core (Zn-PC) and a Zn2+-polyarginine shell (Zn-PA). In a reactive oxygen species (ROS) rich injury microenvironment, oxidation of guanidino groups in the polyarginine shell enables in situ nitric oxide (NO) release and weakens Zn2+ coordination, triggering controlled shell disassembly for early modulation of local inflammation and tissue microenvironment. The subsequent release of PC and Zn2+ provides continuous antioxidant protection. Zn2+ further restores mitochondrial quality control by regulating the STAT3-FOXO3a-SOD2 axis, thus enhancing mitochondrial autophagy, enhancing endogenous antioxidant defense, and restoring mitochondrial homeostasis and energy metabolism. In a mouse spinal cord contusion model, Zn-PC/PA@Gel mitigated inflammation and oxidative stress, alleviated the burden of mitochondrial dysfunction, protected neurons, and promoted motor recovery, resulting in a Basso Mouse Scale (BMS) score of 7.0 on day 28. Overall, these results support Zn2+ coordinated cascade therapy nanoassembly, which combines microenvironmental regulation with mitochondrial homeostatic recovery to reduce secondary injury after SCI and promote locomotor improvement.",

In this study, we evaluated the peripheral and central effects of clemastine on cognitive impairment induced by UC using an acetic acid (1\u00a0ml, 4% v/v) model with emphasis on the role of PI3K/Akt/GSK-3\u03b2 signaling, ferroptosis, and autophagy in its possible mediated neuroprotection. Clemastine revealed a dose-dependent improvement of colonic damage linked with UC, as demonstrated by inhibition of TNF-\u03b1, IL-1\u03b2, and caspase-3 levels along with upregulation of claudin-1 expression. Importantly, the preservation of gut membrane integrity was associated with amelioration of UC-induced systemic inflammation together with restoration of PI3K/Akt/GSK-3\u03b2 signaling in the brain. Additionally, the neuroprotective actions of clemastine included the prevention of neuronal injury and death as evidenced by inhibition of oxidative stress markers and microglial activation (Iba-1 expression), which could exacerbate the neuroinflammatory response. Concurrently, inhibition of the pathological autophagic dysfunction and ferroptosis profile by clemastine, as clarified by LC3-II downregulation and LC3-I and GPX4 upregulation, led to behavioral and cognitive improvements, which were proven by decreased levels of A\u03b2 and tau protein. Importantly, by crossing the BBB, clemastine could exert additional anti-inflammatory and neuroprotective effects by affecting the central assessed pathways. In conclusion, these findings clarify the pivotal role of clemastine in the management of colonic inflammation-associated cognitive decline through modulating multiple and interacting peripheral and central pathways to provide its potent neuroprotection.",

While metabolic reprogramming is linked to immune evasion, the precise mechanistic orchestration remains unclear. Here, utilizing single-cell transcriptomics and quantitative lactylome profiling, we show that elevated tumor lactate drives resistance by broadly suppressing PANoptosis. Mechanistically, under chemotherapeutic stress, the Lysine acetyltransferase 8 (KAT8) catalyzes the specific lactylation of the inner mitochondrial membrane ADP/ATP translocator 2 (ANT2)\u00a0at K92. Lactylated ANT2 recruits the phosphoglycerate mutase 5\u00a0(PGAM5) to dephosphorylate Cyclophilin D (CypD). This cascade restricts mitochondrial permeability transition pore (mPTP) opening, preserving mitochondrial homeostasis and averting immunogenic cell death. Crucially, a cell-penetrating competitive peptide targeting the KAT8-ANT2 interface effectively uncouples this metabolic lock, re-sensitizing TNBC tumors to cytotoxic stress and restoring chemo-immunotherapy efficacy in vivo. Our findings unveil a profound mechanistic link between the Warburg effect and mitochondrial homeostasis, establishing KAT8-mediated ANT2 lactylation as a targetable vulnerability to improve chemo-immunotherapy efficacy.",

Mesenchymal stem cell (MSC)-derived exosomes have emerged as important mediators of intercellular communication and carry microRNAs with potential neuroprotective properties. This study aimed to explore the role and underlying mechanism of human umbilical cord MSC (hUMSC)-derived exosomal miR-486-5p in experimental SCI. Exosomes were isolated from hUMSCs and characterized by transmission electron microscopy, nanoparticle tracking analysis, and exosomal marker expression. A rat SCI model and an LPS-induced PC12 cell inflammatory injury model were established. Histological injury and apoptosis were assessed by HE staining and TUNEL assay. Inflammatory cytokine levels were measured by ELISA. Cell viability, apoptosis, and gene and protein expression were evaluated using CCK-8 assay, flow cytometry, qPCR, and western blotting. A dual-luciferase reporter assay was performed to validate the interaction between miR-486-5p and PTEN. hUMSC-derived exosomes attenuated spinal cord tissue damage, reduced neuronal apoptosis, and suppressed inflammatory cytokine production in vivo and in vitro. Inhibition of exosomal miR-486-5p partially reversed these protective effects. Mechanistically, miR-486-5p directly targeted the 3'-UTR of PTEN, leading to reduced PTEN expression and enhanced phosphorylation of AKT and mTOR. These findings indicate that exosomal miR-486-5p contributes to the regulation of apoptosis- and inflammation-associated molecular events following SCI, primarily through modulation of the PTEN/AKT/mTOR signaling pathway. Given the experimental design, these results should be interpreted as mechanistic insights rather than evidence of functional recovery. hUMSC-derived exosomal miR-486-5p alleviates apoptosis and inflammation following SCI by targeting PTEN and activating the AKT/mTOR pathway. These findings provide mechanistic support for the potential application of exosome-based miRNA therapy in SCI.",

Its clinical management is challenging due to its heterogeneity, highly malignant nature, and insensitivity to standard treatments. While current strategies for GBM treatments are based on inducing apoptosis in GBM cells, some GBM tumors showed resistance to this type of cell death. Recent evidence indicates that pyroptosis is a novel, promising therapeutic method for overcoming tumor cells' resistance to cancer treatment. This inflammatory programmed cell death type is mediated by the cleavage of gasdermin proteins. Based on the evidence, inducing pyroptosis is negatively associated with GBM growth and development; the exact molecular mechanisms and the signaling pathways underlying pyroptosis are not fully understood. This review presents the different pathways of pyroptosis and its role in GBM growth regulating and illustrates various drugs and components that modulate pyroptosis in GBM tumors. It also investigates the regulatory roles of noncoding RNAs in pyroptosis modulation in GBM tumors, providing promising therapeutic approaches that target pyroptosis as a novel strategy for GBM treatment.",

A total of 254 publications related to ferroptosis in ICH from the Web of Science Core Collection and Scopus databases (2014-2025) were analyzed using Bibliometrix, VOSviewer, and CiteSpace. Bibliometric analyses were performed to evaluate publication trends, research hotspots, collaboration networks, and emerging themes. Publication output increased markedly after 2020, reflecting growing attention to ferroptosis-related brain injury after ICH. China contributed nearly 80% of the publications, although international collaboration remained relatively limited. Keyword evolution and co-citation analyses showed that the research focus gradually shifted from general cell death pathways toward more specific mechanisms involving iron metabolism, lipid peroxidation, GPX4-mediated antioxidant regulation, and neuroinflammation.

Vagus nerve stimulation (VNS) has been used to treat emotional distress, while the underlying mechanisms remain elusive. A chronic restraint stress (CRS)-induced mouse anxiety model in vivo and a corticosterone (CORT)-induced neuronal cell death model in vitro were employed, followed by treatment with vagus nerve stimulation and \u03b17nAChR agonists or antagonists. Anxiety levels were assessed using the open field test (OFT), elevated plus maze (EPM), and novelty-suppressed feeding test (NSFT). Histopathological staining and immunofluorescence staining were performed to detect the pathological changes of neuronal injury in anxiety disorders. Western blot was conducted to measure the protein expression levels of GPX4, SLC7A11, and ACSL4. Enzyme-linked immunosorbent assay (ELISA) was used to measure the expression levels of anxiety-related pro-inflammatory cytokines, while quantitative real-time polymerase chain reaction (qPCR) was employed to detect the mRNA expression levels of GPX4, SLC7A11, and ACSL4. In this study, we found that VNS significantly alleviated anxiety-like behaviors, reduced hippocampal ferroptosis-related damage and inflammatory responses in anxiety mice. \u03b17nAChR antagonist abolished VNS-mediated protective effects against ferroptosis-related neuronal damage and anxiety, while \u03b17nAChR agonists produced similar anxiolytic effects to VNS. Mechanistically, VNS activated \u03b17nAChR signaling, thereby upregulating the expression of GPX4 and SLC7A11, inhibiting ACSL4-mediated lipid peroxidation, and ultimately suppressing anxiety-induced ferroptosis-related neuronal damage. This study reveals a novel mechanism underlying the anxiolytic effect of VNS, that is, by activating \u03b17nAChR signal, VNS inhibits CRS-induced ferroptosis-related neural damage. Our findings provide new insights into mechanism of anxiety disorders and lay a theoretical foundation for the clinical application of VNS.",

Its active metabolite, icariin (ICT), along with its fluorinated derivative, trifluoro-icaritin (ICTF), has been shown in our previous research to alleviate neuropathic pain induced by spared nerve injury (SNI) through an \u03b17 nicotinic acetylcholine receptor (\u03b17nAChR)-dependent pathway. Neuropathic pain remains a significant and unresolved health issue. Ferroptosis has recently been identified as a key, yet insufficiently explored, aspect, and the interaction between ferroptosis and the spinal cholinergic anti-inflammatory receptor \u03b17nAChR remains entirely unknown. This study aims to investigate whether ferroptosis serves as a critical mechanistic link between \u03b17nAChR and the analgesic effects of ICTF. A spared nerve injury (SNI) rat model was established to investigate neuropathic pain. Pain-related behaviors were assessed through paw withdrawal threshold (PWT) and CatWalk gait analysis. Western blotting and immunofluorescence were employed to detect protein expression and co-localization. Moreover, transcriptomic sequencing of spinal cord tissue was conducted to identify candidate pathways. To establish causality, two independent reverse validation approaches were utilized, including the administration of the ferroptosis agonist Erastin and intrathecal injection of adeno-associated virus to knock down \u03b17nAChR. Transcriptomic analysis revealed a significant enrichment of ferroptosis-associated gene signatures in SNI rat spinal cords, characterized by marked upregulation of pro-ferroptotic genes, including Cybb, Sat1, and Hmox1. Concurrently, SNI markedly decreased neuronal expression of \u03b17nAChR and the ferroptosis-inhibitory enzyme GPX4. Treatment with ICTF (5.0\u202fmg/kg, intraperitoneally), the optimal dosage screened in our prior study, effectively counteracted these alterations, accompanied by attenuation of iron overload, lipid peroxidation, and oxidative stress within the spinal cord. Reverse validation further demonstrated that Erastin abolished the analgesic and motor-improving effects of ICTF, while concurrently suppressing \u03b17nAChR and GPX4 expression. Moreover, \u03b17nAChR knockdown produced comparable effects, negating ICTF-mediated benefits and further reducing GPX4 levels. We found that spinal ferroptosis is markedly activated in SNI rats, thereby exacerbating neuroinflammation and mechanical allodynia. Importantly, ferroptosis suppresses the expression of \u03b17nAChR, while ICTF interrupts this vicious cycle by upregulating \u03b17nAChR, inhibiting ferroptosis-related iron accumulation, lipid peroxidation, and the downregulation of GPX4, ultimately alleviating SNI-induced neuropathic pain. This study offers a scientific interpretation of the traditional use of Epimedium-derived active compounds for treating neuropathic pain at the modern molecular mechanism level.",

Botulinum neurotoxin type A (BoNT/A) has shown anti-inflammatory and neuroprotective effects in acute SCI, but its potential in the chronic phase remains unclear. This study investigates whether combining BoNT/A with electrical muscle stimulation (EMS) enhances recovery in chronic SCI. Adult mice with severe thoracic SCI (paraplegic) underwent EMS (30\u00a0min/d for 10 non-consecutive days starting 3 d post-injury) or no stimulation. Fifteen days after SCI, animals received a single intrathecal injection of BoNT/A (15\u00a0pg/5\u00a0\u03bcl) or saline. Functional recovery was assessed up to 60 d as well as in moderate and mild SCI mice. NeP onset and maintenance were evaluated. Spinal cord tissue was analysed for astrocytic and microglial morphology, neuronal and oligodendroglial survival, myelin protein expression, and in vitro effects on oligodendrocyte precursor cells (OPCs). The phenotype of hindlimb muscles was evaluated through morphological and gene expression analyses. EMS was able to counteract muscle atrophy and fibrosis, and when combined with BoNT/A, also denervation. Moreover, the combination restored hindlimb motor function in chronic SCI, whereas BoNT/A or EMS alone were ineffective. NeP, a common comorbidity associated with SCI, was mitigated by BoNT/A treatment even when administered in the chronic phase. BoNT/A reduced astrocytic hypertrophy and excitatory synapse association and was associated with a morphology-based redistribution of microglial profiles toward a resting-like classification, decreased apoptosis, and increased neuronal and oligodendroglial survival. Myelin basic protein (MBP) expression was significantly elevated in vivo. In vitro, BoNT/A promoted OPC differentiation into myelinating oligodendrocytes, increased process complexity, and upregulated MBP, galactocerebroside C, proteolipid protein, and myelin oligodendrocyte glycoprotein under both proliferative and differentiating conditions. Cleaved synaptosomal-associated protein 25 colocalization with OPC confirmed direct BoNT/A internalization and activity. BoNT/A exerts neuroprotective effects in chronic SCI by reducing neuroinflammation and supporting neuronal and oligodendroglial preservation. When combined with EMS, it also promotes remyelination and improves muscle homeostasis, suggesting that early stimulation creates a permissive environment for recovery. These findings support the clinical evaluation of BoNT/A as a therapeutic strategy for chronic SCI.",

Neuroinflammation and neuronal apoptosis are two critical factors in the pathological process of SCI. Although electroacupuncture (EA) has been reported to alleviate neuroinflammation in brain injury, the underlying molecular mechanism remains unclear. Transcriptome sequencing of spinal cord tissues was performed to identify potential key factors and pathways involved in EA post-SCI. DHCR24, a cholesterol synthesis regulator, was selected as a key candidate and DHCR24 was downregulated after SCI (log2FC = -1.6, P\u2009<\u20090.01), and this downregulation was notably reversed by EA treatment (log2FC\u2009=\u20091.04, P\u2009<\u20090.01). We investigated the neuroprotective effect of DHCR24 against neuron death and neuroinflammation in SCI, with a particular focus on its effects on the Wnt signaling pathway. SCI-induced DHCR24 downregulation was associated with decreased expression of the axonal regeneration marker NF and increased activation of Iba1/CCR7-positive microglia, accompanied by enhanced neuronal apoptosis and inflammatory factor release. Importantly, functional validation experiments demonstrated that DHCR24 was required for the therapeutic effects of EA. Complementary in vitro studies in LPS/IFN-\u03b3-stimulated BV2 microglia cells confirmed the role of DHCR24 in microglial polarization and neuronal survival, likely via Wnt signaling activation. Integrating transcriptomic and mechanistic evidence, we demonstrate that DHCR2 promotes Wnt pathway activation, reduces neuronal apoptosis and neuroinflammation, and ultimately enhances spinal cord repair. This study provides evidence supporting the potential clinical application of EA in SCI recovery and identifies DHCR24 may be a key mechanistic target underlying its therapeutic effects.",

Here, we designed 50 hybrids combining the benzimidazole-aminofurazan scaffold of a BChE inhibitor (S06-1064) with the 1,2,4-oxadiazole moiety of an Nrf2 activator (6). After four optimization rounds, S27-1046 and S27-1047 emerged as potent, selective BChE inhibitors and Nrf2 activators (S27-1046: eqBChE IC50\u202f=\u202f2.51\u202f\u00b1\u202f1.51\u202fnM, hBChE IC50\u202f=\u202f128.30\u202f\u00b1\u202f16.89\u202fnM, FP IC50\u202f=\u202f188.20\u202f\u00b1\u202f57.11\u202fnM, 4.73-fold ARE induced fold at 20\u202f\u03bcM; S27-1047: eqBChE IC50\u202f=\u202f7.16\u202f\u00b1\u202f2.96\u202fnM, hBChE IC50\u202f=\u202f296.10\u202f\u00b1\u202f55.78\u202fnM, FP IC50\u202f=\u202f36.87\u202f\u00b1\u202f23.07\u202fnM, 7.42-fold ARE induced fold at 20\u202f\u03bcM). They directly bind Keap1, disrupt Keap1-Nrf2 interaction, enhance antioxidant enzyme expression, and activate the GSH-GPX4 axis to inhibit A\u03b2-induced ferroptosis. Both compounds also protect against oxidative stress and neuroinflammation. S27-1047 showed superior Nrf2 activation and Keap1 binding, thus was selected for in vivo evaluation. In an A\u03b2-induced AD mouse model, S27-1047 significantly improved cognition, outperforming mono- or combination therapies. It has 12.62% oral bioavailability and crosses the BBB. This work presents multi-target agents targeting BChE, Nrf2, and ferroptosis for effective AD therapy.",

Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.",

SCI rat models and H2O2-treated C8-D1A/C8-B4 cellular models were established. miR-425-5p and CREB1 were manipulated using inhibitors/antagomirs and siRNAs. Expression levels of miR-425-5p, IL-6, IL-1\u03b2, TNF-\u03b1, CREB1, and caspase-3 were measured using RT-qPCR. Cell apoptosis was evaluated by flow cytometry. Western blot analysis was performed to assess total CREB1 (t-CREB1) and phosphorylated CREB1 (p-CREB1) levels. Bioinformatics predictions were used to determine the targeting relationship between miR-425-5p and CREB1. BBB locomotor rating scale was employed to quantify motor function recovery in rats. miR-425-5p expression was markedly up-regulated in the H2O2-induced cell model, whereas CREB1 was down-regulated. CREB1 is a target of miR-425-5p. Inhibition of miR-425-5p significantly reduced apoptosis, suppressed pro-inflammatory cytokine expression, thereby promoting motor recovery; these effects were partially reversed by CREB1 knockdown. In SCI rats, miR-425-5p antagomir treatment alleviated inflammation and promoted motor function recovery; these beneficial effects were partially suppressed by co-administration of si-CREB1 to knockdown CREB1. MiR-425-5p upregulation in SCI directly suppresses CREB1 expression, subsequently exacerbating neuroinflammation, which in turn impairs functional recovery.",

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.",

Cell reprogramming-based therapies have emerged as promising therapeutic avenues for neuronal replenishment. However, their therapeutic potential in neural regeneration still faces formidable challenges, including risks of viral vector gene delivery, potential damage from cell transplantation, and significant glial scar (GS) formation following CNS injury. Therefore, developing an optimal approach that simultaneously replaces lost neurons and overcomes these persistent obstacles is crucial for neural regeneration and functional recovery. We engineered a non-viral gene delivery platform using biodegradable poly(\u03b2-amino ester) (PBAE) nanoparticles (NPs) to effectively co-deliver plasmids encoding proneural transcription factors ASCL1 and NGN2 directly to astroglia (ATG) within GS region, in combination with neural induction. The biochemical and physiological properties of reprogrammed ATGs were characterized both in vivo and in vitro. The therapeutic potential of PBAE-A/N delivery was assessed in spinal cord injury (SCI) animal models through behavioral evaluations. Finally, the molecular mechanisms underlying ASCL1/NGN2-mediated ATG-to-neuron reprogramming were investigated. PBAE-mediated delivery of ASCL1/NGN2 plasmids effectively reprogrammed resident ATGs within GSs into functional neurons, as evidenced by the acquisition of neuronal morphology and biochemical phenotype (neuronal marker expression), loss of ATG characteristics, scar remodeling, and functionality indistinguishable from those of genuine neurons, including specialized calcium signaling, synaptic activity, and action potential firing. Critically, local administration of PBAE-ASCL1/NGN2 NPs into the GS region of the injured spinal cord significantly ameliorated neurological deficits. Mechanistically, this reprogramming event likely involved the modulation of downstream targeting signaling mediated by Cend1, RanBPM, and Dyrk1, along with crosstalk with the Notch1/Cyclin D1 axis. This study demonstrates that PBAE-mediated ASCL1/NGN2 delivery enables in situ reprogramming of ATG into functional neurons while actively dissolving GSs, thereby addressing both neuronal loss and GS barriers in CNS repair. The identified Cend1/RanBPM/Dyrk1 signaling and its crosstalk with Notch1/Cyclin D1 axis provide mechanistic insights into the events. Collectively, this work presents a novel therapeutic alternative for CNS repair and neurodegeneration by simultaneously replacing lost neurons and eliminating endogenous GSs through in situ cell reprogramming.",
        "42403480": "ID: 42403480\nTitle: The ferroptosis-mediated domino effect: metabolic crosstalk from intervertebral disc degeneration to spinal deformity and cord injury: a mini review.\nAbstract: Spinal degeneration, spinal deformity, and spinal cord injury (SCI) are classically managed as discrete biomechanical or neurological entities. However, emerging evidence reveals them as an interconnected pathological continuum. This mini-review introduces the \"ferroptosis-mediated domino effect\" as the core metabolic driver linking these conditions. The cascade initiates within the avascular intervertebral disc, where aberrant mechanotransduction (e.g., via Piezo1) provokes severe oxidative stress and subsequent ferroptosis, leading to extracellular matrix degradation and structural collapse. The ensuing spinal deformity chronically compresses the spinal microvasculature, disrupting the blood-spinal cord barrier (BSCB) and facilitating localized iron deposition. This chronic ischemic insult generates a metabolically \"primed\" spinal cord characterized by extreme vulnerability. Upon secondary acute trauma, the sudden influx of heme and labile iron ignites an uncontrollable \"ferroptotic storm,\" synergizing with neuroinflammation to drive irreversible neural loss. Finally, we evaluate cutting-edge translational interventions-including reactive oxygen species (ROS)-responsive nanoparticles and nanozyme-loaded hydrogels-that offer spatiotemporal precision to halt this pathological crosstalk. By dismantling disciplinary silos, this framework advocates for next-generation, dual-action therapeutic strategies that simultaneously restore biomechanical stability and mitigate metabolic collapse.",

Although its immunomodulatory functions are well-established, its role in inflammation following spinal cord injury (SCI) remains unclear. This study aimed to elucidate the regulatory role of microglial Tim-3 in the sterile inflammatory response after SCI and to explore its potential as a therapeutic target. A SCI model was established using C57BL/6 mice. Microglial Tim-3 function was investigated through adeno-associated virus-mediated Tim-3 overexpression and intervention with the Nrf2 agonist Oltipraz. Luxol fast blue (LFB) and Nissl staining were used to assess lesional area and tissue structure. Basso Mouse Scale (BMS) scoring and the sucrose preference test (SPT) were employed to evaluate motor function recovery and depressive-like behavior. Immunofluorescence was performed to analyze glial activation and neurodegeneration. Expression levels of inflammatory factors were measured by enzyme-linked immunosorbent assay (ELISA) and western blot (WB). Microglia-specific Tim-3 overexpression promoted microglial proliferation and activation, inducing upregulation of iNOS and robust production of pro-inflammatory cytokines. This exacerbated neural tissue damage and motor dysfunction, whereas depressive-like behaviors were not significantly affected. These effects were partially reversed by the Nrf2 agonist. AAV-mediated microglial Tim-3 overexpression exacerbates neuroinflammation and functional impairment after SCI, potentially through an association with the Nrf2/HMGB1 signaling axis. Targeting microglial Tim-3 may represent a promising therapeutic strategy for SCI.",

CASC11, miR-130b-5p, and SPP1 levels were measured by real-time quantitative polymerase chain reaction (RT-qPCR). Cellular functions and targeting relationships were assessed via cell counting kit-8 (CCK-8), flow cytometry, western blot, enzyme-linked immunosorbent assay (ELISA), dual-luciferase reporter, and RNA immunoprecipitation (RIP) assays. CASC11 was highly expressed in SCI and associated with inflammation as a potential diagnostic biomarker. In lipopolysaccharide (LPS)-treated PC-12 cells, silencing CASC11 alleviated suppressed cell activity, apoptosis, and inflammation, which was reversed by miR-130b-5p inhibitor. These findings suggest that CASC11 is associated with SCI severity, while in vitro data indicate its involvement in inflammatory and apoptotic responses through the CASC11/miR-130b-5p/SPP1 axis.

Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND.",

Neuronal apoptosis constitutes a critical pathological event leading to neurological dysfunctions, which is further exacerbated by oxidative stress following SCI. Esculentoside A (EsA), a bioactive saponin isolated from Phytolaca esculenta, exhibits neuroprotective potential in our preliminary studies. However, whether EsA attenuates oxidative stress and neuronal apoptosis in SCI remains unclear. The current study aimed to investigate the protective potential of EsA against oxidative stress and neuronal apoptosis following SCI, and to elucidate the associated molecular mechanisms. SCI was modeled in rats via contusion using the PSI-IH 0400 Striker impactor, and rats were treated intraperitoneally with 10 mg/kg EsA once daily. The Basso, Beattie, and Bresnahan (BBB) scale, grid walk analysis, and footprint test were adopted to evaluate motor function dynamically. Histopathological alterations in spinal cord tissue were examined by Hematoxylin-eosin (HE), Luxol Fast Blue (LFB), and Nissl staining. Oxidative stress markers, including hydrogen peroxide (H2O2) and malondialdehyde (MDA), along with antioxidant enzymes glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD), were quantified in spinal cord homogenates using commercial assay kits. Western blot, immunofluorescence staining, and molecular docking were employed to investigate the underlying mechanisms. EsA significantly improved motor function and reduced histopathological damage in SCI rats. This neuroprotective effect was accompanied by a significant improvement in oxidative stress biomarkers and neuronal apoptosis in the injured spinal cord, coinciding with activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. In conclusion, EsA exerts a neuroprotective effect against SCI by modulating oxidative stress and neuronal apoptosis partially through activation of the Nrf2/HO-1 pathway, indicating its promise as a therapeutic agent for SCI.",

The degenerative disc's harsh microenvironment promotes nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) death and hinders self repair. Mesencephalic astrocyte-derived neurotrophic factor (MANF), an atypical neurotrophic factor, has protective effects in degenerative diseases. However, its role in IDD is unclear. Assessment of MANF expression was conducted in both human nucleus pulposus tissues and a rat IVD puncture model. An in vitro model of degeneration was established by acid treatment of NP-MSCs, and the functional role of MANF was explored through its knockdown and overexpression. RNA sequencing was employed to identify downstream targets. The therapeutic potential of MANF-overexpressing NP-MSCs was evaluated in a rat puncture model. MANF expression was markedly downregulated in degenerated IVD tissues from both human patients and rat models. Correspondingly, in vitro experiments demonstrated that MANF knockdown exacerbated, while its overexpression mitigated, acid-induced apoptosis of NP-MSCs. Mechanistically, MANF attenuated mitochondrial dysfunction and ER stress of NP-MSCs under acidic conditions by maintaining MAM integrity, as demonstrated by the complete abolition of this protection upon treatment with the MAM uncoupler FATE1. Transcriptomic analysis and subsequent validation identified receptor expression-enhancing protein 1 (REEP1) as a critical downstream effector through which MANF safeguards MAM integrity. We further elucidated that MANF upregulates REEP1 expression by directly inhibiting miR-33b-5p. In vivo, transplantation of MANF-overexpressing NP-MSCs effectively attenuated IDD in a rat model. MANF protected NP-MSCs from acidosis by sustaining MAM integrity via the MiR-33b-5p/REEP1 axis. These findings reveal MANF's mechanism and therapeutic potential for IDD.",

Here we report that stereotaxic OxPC deposition in the mouse spinal cord GM induces age dependent neuroinflammation and neurodegeneration. Microglia are the predominant macrophages responding to OxPC induced GM lesions and help to mitigate acute neurodegeneration. Neuronal necroptosis activation in mouse GM lesions and neuronal upregulation of OxPCs and necroptosis activation in MS GM lesions suggest OxPC induced necroptosis promote GM degeneration during MS. In support, necroptosis inhibition ameliorates OxPC induced GM neuron loss. Finally, iron(ii)-containing heme deposition in the GM induces both OxPC formation and neuronal necroptosis activation, suggesting an endogenous upstream mechanism for generating neurotoxic OxPCs. These results highlight a plausible link between heme deposition, lipid peroxidation, and neuronal loss, and that necroptosis inhibition could help prevent GM neurodegeneration during MS.",

Brains and spinal cords were collected 2-3\u00a0weeks post-injection or between 6-10 and 11-15\u00a0months of age. Immunohistochemical studies of transgene expression throughout the brain and spinal cord using an antibody selective for human APP (hAPP) revealed age-dependent accumulation of clusters of hAPP-positive granules in areas containing hAPP-labeled neuronal cell bodies. Surprisingly, there were also hAPP-positive granules in regions containing axons and synaptic terminals from hAPP expressing neurons. Moreover, tdT expressed by CSNs accumulated in the same granules as hAPP, and both tdT and hAPP were present in clusters of granules with other markers of AD pathology. Quantitative assessments confirmed age-related degeneration of layer V CSNs accompanied by progressive accumulation of clusters of tdT and hAPP-positive granules. Overall, our results indicate that accumulation of aggregated hAPP in areas containing axons and synaptic terminals from hAPP expressing neurons is a prominent feature of AD pathophysiology in 5xFAD mice and that accumulation of clusters of hAPP granules provides a secondary measure to track neurodegeneration of identified populations of genetically labeled neurons.",

Recent evidence suggests that STING activation can induce neuronal ferroptosis through autophagic degradation of GPX4. Taurochenodeoxycholic acid (TCDCA), a naturally occurring bile acid, has demonstrated neuroprotective properties through activation of Takeda G protein-coupled receptor 5 (TGR5). However, whether TCDCA can improve PD by modulating the cGAS-STING-ferroptosis axis remains unexplored. We investigated the effects of TCDCA treatment on motor function, dopaminergic neuronal survival, oxidative stress markers, ferroptosis-related proteins (GPX4, SLC7A11, ACSL4), and cGAS-STING signaling components in the substantia nigra of male mice subjected to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration and in MPP\u207a-treated SH-SY5Y cells. Behavioral assessments demonstrated that TCDCA significantly improved motor dysfunction in both open field and pole tests. TCDCA treatment markedly increased tyrosine hydroxylase-positive neurons and reduced oxidative stress markers including malondialdehyde and ferrous iron levels while restoring superoxide dismutase activity and glutathione content in the substantia nigra. Results showed that TCDCA upregulated TGR5 expression and concurrently suppressed cGAS and STING activation in both in vivo and in vitro PD models. Importantly, TCDCA treatment significantly enhanced the expression of anti-ferroptotic proteins GPX4 and SLC7A11 while reducing pro-ferroptotic ACSL4. These neuroprotective effects were associated with TGR5 upregulation and cGAS-STING pathway suppression. Our findings demonstrate that TCDCA alleviates PD-related neurodegeneration by inhibiting cGAS-STING-mediated ferroptosis through TGR5 activation, suggesting that TCDCA holds promise as a candidate drug for the treatment of PD.",

Prior work has advanced redox dysregulation, neuroinflammation, and NMDA receptor hypofunction as a putative central hub in schizophrenia. This narrative review proposes an evidence-weighted redox-mitochondria-immune framework that integrates peripheral biomarkers, magnetic resonance spectroscopy, postmortem findings, and preclinical mechanisms while explicitly distinguishing established observations from candidate pathways. Existing studies support increased oxidative damage and altered antioxidant buffering in schizophrenia, particularly involving the glutathione system. However, these abnormalities are neither uniform across disease stages nor equally represented across patient subgroups, and may be markedly prominent only in certain biological subgroups. Mechanistically, redox imbalance may interact with mitochondrial bioenergetic deficits and innate immune signaling; however, pathway-specific links such as cGAS-STING activation, nitrosative/peroxynitrite stress, and GPx4-ferroptosis should currently be treated as testable extensions rather than validated human mechanisms in schizophrenia. Importantly, the pathological consequences of oxidative stress are unlikely to be cell-type neutral. Parvalbumin-positive interneurons and oligodendrocyte lineage cells are more vulnerable because of their high metabolic load, limited antioxidant buffering capacity, and lipid/iron-related susceptibility, thereby providing a mechanistic bridge to excitation-inhibition imbalance, myelin abnormalities, and reduced circuit synchrony. Microglial redox-inflammatory signaling may further exacerbate these processes. On the basis of this framework, we argue that the key for future research is not to continue demonstrating the universality of oxidative stress, but to improve the translational efficiency. Biomarker-guided stratification, stage-sensitive study designs, and cell-type-informed therapeutic strategies may therefore provide a more productive path toward redox-targeted interventions in schizophrenia.",

This study innovatively employs a comparative knockout paradigm, utilizing neural lineage knockout (Nrf2flox/flox; Nestin-Cre, targeting neural progenitor cells and their derived lineages) and astrocyte-biased knockout (Nrf2flox/flox; GFAP-Cre) mouse models, combined with an in vitro co-culture system, to elucidate the lineage-dependent and differential protective mechanisms of Nrf2 in acute IS (AIS). Results demonstrated that both knockout models exacerbated neurological deficits, increased cerebral infarct volumes, and reduced cerebral blood flow. However, a marked phenotypic divergence was observed. The Nestin-Cre model exhibited more severe neurological deterioration, associated with dysregulated iron metabolism, enhanced lipid peroxidation, and aggravated neuroinflammation, suggesting a predominant role for neuronal Nrf2 in counteracting ferroptosis and neuroinflammatory responses. In contrast, the GFAP-Cre model did not induce ferroptosis but promoted neurotoxic A1-type astrocyte polarization and enhanced inflammatory injury via NF-\u03baB pathway activation. This finding underscores the unique function of astrocytic Nrf2 in modulating the neuroinflammatory microenvironment. These cell-type-specific effects were further validated in an in vitro oxygen-glucose deprivation/reoxygenation (OGD/R) model. Through this cross-lineage comparative analysis, our study systematically elucidates, for the first time, the distinct protective mechanisms of Nrf2 in neurons and astrocytes, thereby advancing understanding of its functional heterogeneity and providing a novel theoretical basis for developing cell-type-biased, Nrf2-targeted therapeutic strategies.",

However, despite encouraging preclinical and clinical findings, therapeutic outcomes remain highly heterogeneous, with marked variability in graft retention and functional efficacy between patients. Increasing evidence suggests that this variability cannot be explained solely by procedural factors or cellular composition, but may also depend on host-related immune and microenvironmental determinants. This review explores the biological mechanisms governing SVF engraftment and introduces the emerging concept of \"SVF therapy resistance,\" defined as the failure of autologous regenerative therapies resulting from maladaptive interactions between transplanted stromal cells and the host tissue environment. Particular attention is given to sterile inflammation, innate immune activation, and early graft-host interactions. Following transplantation, tissue injury and ischemia induce the release of danger-associated molecular patterns (DAMPs), triggering neutrophil recruitment, macrophage activation, complement signaling, and inflammatory remodeling. While controlled inflammatory responses may support tissue repair and angiogenesis, excessive neutrophil activation, neutrophil extracellular trap (NET) formation, persistent pro-inflammatory macrophage polarization, and impaired vascular adaptation may compromise graft survival and regenerative efficacy. The review further discusses how SVF processing, inflammatory priming, stromal cell heterogeneity, and donor-related factors-including obesity, aging, metabolic dysfunction, and chronic inflammation-may influence therapeutic responsiveness. Emerging evidence from mesenchymal stromal cell biology suggests that stromal cells are highly sensitive to inflammatory licensing and microenvironmental cues. Candidate biomarkers and immune profiling strategies capable of identifying responders and non-responders to SVF-based therapies are also reviewed. Finally, these mechanisms are discussed in spinal cord injury, a condition characterized by chronic inflammation and vascular dysfunction. Overall, this review proposes a translational framework linking innate immunity, sterile inflammation, angiogenesis, and stromal cell heterogeneity to the variability of SVF therapy outcomes, highlighting the need for personalized regenerative medicine approaches.",

Central to this inflammatory milieu is pyroptosis, a highly inflammatory form of programmed lytic cell death mediated by gasdermin proteins. This comprehensive review provides an in-depth synthesis of the cellular and molecular mechanisms underlying pyroptosis in AD. We detail the distinct roles of microglia as primary initiators responding to amyloid-beta (A\u03b2) and tau aggregates, alongside the specific vulnerabilities of neurons facing oxidative stress, astrocytes impacting metabolic support, and endothelial cells whose pyroptotic death contributes directly to blood-brain barrier disruption. At the molecular level, the priming and activation of the NLRP3 and NLRP1 inflammasomes by diverse triggers, including classical markers like A\u03b2, environmental neurotoxicants and metabolic stressors, converge on caspase-1 and caspase-8 activation. This cascade culminates in gasdermin D (GSDMD) and gasdermin E (GSDME) pore formation, leading to cellular lysis and the massive release of pro-inflammatory cytokines such as IL-1\u03b2 and IL-18. Furthermore, this paper explores the emerging and critical concept of PANoptosis, highlighting the intricate crosstalk between pyroptosis, apoptosis, and necroptosis within PANoptosome complexes triggered by mitochondrial dysfunction. We evaluate current and prospective therapeutic strategies, ranging from multi-target natural and traditional herbal remedies to advanced nanomedicine, synthetic small molecules, and epigenetic gene therapies. By integrating insights from blood-based pyroptosis-associated molecular signatures and advanced targeted drug delivery systems, we emphasize the critical need for personalized, multi-targeted approaches to successfully harness pyroptosis modulation in the clinical management and treatment of AD.",

The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders.",

We investigated the role of sphingosine-1-phosphate receptor 2 (S1P2 receptor) in contusive spinal cord injury and evaluated the therapeutic effects of an S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) in a rat model of SCI. The SCI model was established using a 10\u2009g weight dropped onto the T10 vertebrae in female rats. After functional testing, spinal cords were harvested for biochemical and histopathological assays at different time points. Nissl and Prussian blue staining were used to analyse neuronal death. Neuronal ferroptosis in spinal cords was examined using transmission electron microscopy, and lipid peroxidation in the cultured neurones was analysed. After SCI, S1P (Sphingosine 1-phosphate) was released from crushed spinal cords and subsequently activated the neuronal S1P2 receptor to increase lipid peroxidation, which injured neurones via inducing neuronal ferroptosis through the P-ERK/ERK/ACSL4 pathway, resulting in limb paralysis. S1P2 receptor inhibition significantly blocked S1P2 receptor activation and attenuated neuronal ferroptosis. Thus, S1P2 receptor was a therapeutic target for the treatment of SCI. Systemic administration of the S1P2 receptor antagonist S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) effectively promoted locomotor function recovery by attenuating neuronal ferroptosis in rat spinal cords. S118 impeded neuronal ferroptosis by inhibiting lipid peroxidation. Contusive SCI is characterised by neuronal loss due to S1P2 receptor activation in spinal neurones. S1P2 receptor activation increases lipid peroxidation, which induces neuronal ferroptosis. S118 (C\u2081\u2089H\u2081\u2084Cl2FN\u2087O) improves locomotor functional recovery by preserving the spinal cord structure after SCI.",

Although spinal neuroinflammation is a recognized contributor to neuropathic pain, the role of supraspinal neuroinflammation remains less well defined. This systematic review critically evaluated experimental evidence linking SCI-induced supraspinal neuroinflammation with pain-related behaviors in animal models. A systematic literature search in PubMed, Web of Science Core Collection, and Scopus identified studies published over the last 20 years using rodent SCI models that assessed both supraspinal neuroinflammatory markers and pain-related behaviors. After screening, nine studies met the predefined criteria. The analyzed studies suggested that SCI is associated with supraspinal neuroinflammatory alterations, including increased microglial and astrocytic activation and upregulation of pro-inflammatory cytokines and chemokine-related pathways, in several brain regions. In intervention studies, reduced neuroinflammation was accompanied by improvement in mechanical or thermal pain-related behaviors. However, considerable methodological heterogeneity and moderate to high risk of bias were observed. Current evidence suggests an association between supraspinal neuroinflammatory alterations and chronic pain-related behaviors after SCI, but the limited number of studies and methodological variability restrict firm conclusions. Further well-designed experimental studies are needed to clarify underlying mechanisms.",

Here, we aimed to define the temporal protein-abundance architecture of SHK-1 macrophage-like cells after R. salmoninarum inoculation and to test whether this response supports broad canonical cell-death pathway engagement. We used label-free quantitative LC-MS/MS proteomics to profile SHK-1 cells over a 48 h post-inoculation time course. Because the design included a single non-infected T0 baseline, analyses were framed as baseline-referenced post-inoculation comparisons rather than a fully controlled mock time course. Of 6842 proteins retained for statistical modeling, 2254 were strictly differentially abundant in at least one contrast relative to T0 (adjusted p < 0.05 and |log2FC| \u2265 0.585). Perturbation was strongest at 1-2 h and progressively contracted at later time points. Among 1278 recurrent proteins, k-means clustering resolved four temporal modules capturing coordinated remodeling of lysosomal, immunometabolic, cytoskeletal, stress-response, and antioxidant programs. A curated cell-death panel spanning apoptosis, pyroptosis, necroptosis, ferroptosis, and PANoptosis yielded only three detected markers; CASP3 and MLKL met the strict threshold, whereas ACSL4 remained sub-threshold. Overall, early host-cell remodeling, rather than broad canonical death-program execution, was the predominant proteomic signature of SHK-1 cells during the first 48 h after R. salmoninarum inoculation.",
        "42450339": "ID: 42450339\nTitle: The Immunologic Function of the Choroid Plexus: A Gateway to Immunomodulatory Therapy in Injury Models of the Central Nervous System.\nAbstract: Over time, our understanding of the central nervous system (CNS) as an immunologically privileged site where immune-cell infiltration takes place has changed; research has transformed the dominant view, showing that the CNS is an immunologically specialized tissue featuring complex interactions between the immune system and CNS processes, where the choroid plexus (CP) has an essential role in regulating neuronal tissue homeostasis and immune-cell trafficking. Although immune-cell entry into the CNS is tightly controlled, small numbers of antigen-experienced lymphocytes can access cerebrospinal fluid (CSF) compartments for immune surveillance under normal conditions. During an injury, such as cerebral ischemia or spinal cord damage, dendritic cell precursors infiltrate the CNS, suggesting their involvement in modulating lymphocyte activity. However, the immunoregulatory function of the CP alone is insufficient to prevent damage. Injury can trigger a cascade of events including activation of microglia toward a pro-inflammatory M1 phenotype, infiltration of peripheral immune cells across the blood-brain barrier (BBB), and uncontrolled neuroinflammation. T cells play a critical role in this process. Th1 cells exacerbate inflammation upon recognizing neural antigens, whereas Th2 cells promote recovery by releasing neurotrophic factors. This highlights the dual role of inflammation in CNS injury and repair.",

Currently, there is a notable absence of effective pharmacological agents to prevent or treat neuroinflammatory processes associated with AD. Heat shock protein 70 (HSP70) is pivotal in the progression of neuroinflammation. In this study, we explored the potential of maltol, a Maillard reaction product derived from red ginseng, as a therapeutic agent for neuroinflammation. Methods: In vitro, HMC3 microglial cell models were developed to examine the regulatory effects of gradient concentrations of maltol (12.5, 25, 50 \u03bcM) on the TLR4/MyD88/NF-\u03baB p65 signaling pathway, neuroinflammation, and pyroptosis. Analyses of the GEO database and Gene Set Enrichment Analysis (GSEA) were performed to identify the core targets of maltol, followed by HSP70 gene silencing experiments to validate the targeted regulatory mechanism. Results: Maltol significantly mitigated LPS-induced neuronal damage and cognitive deficits in mice. It effectively suppressed microglia-mediated neuroinflammation and pyroptosis, reversed oxidative stress-induced neuronal ferroptosis, and inhibited neuronal apoptosis. In vitro experiments demonstrated that maltol obstructed TLR4/MyD88 binding, thereby inhibiting NF-\u03baB p65-mediated neuroinflammation and pyroptosis, while also alleviating excessive ROS accumulation to enhance oxidative stress and ferroptosis. Bioinformatics analysis identified HSP70 as a crucial target for the anti-inflammatory and antioxidant effects of maltol. Subsequent gene silencing experiments confirmed that maltol exerted its inhibitory effects on LPS-induced neuroinflammation and pyroptosis in an HSP70-dependent manner. Conclusions: Maltol exhibits significant protective effects against Alzheimer's disease-related neuroinflammation, oxidative stress, pyroptosis, and ferroptosis through the targeting of HSP70. This study elucidates the molecular mechanisms by which maltol improves neuroinflammatory injury and provides a novel theoretical foundation and therapeutic strategy for the intervention of Alzheimer's disease neuroinflammation using traditional Chinese medicine.",
        "42453609": "ID: 42453609\nTitle: PANoptosis in neurological disorders: from inflammatory cell death mechanisms to neuroprotective strategies.\nAbstract: PANoptosis is now regarded as an inflammatory form of programmed cell death (PCD). It reflects the coordinated involvement of apoptosis, pyroptosis, and necroptosis, usually through the PANoptosome in a shared pathological environment. This concept may be especially useful in neurological diseases. It helps explain why neuronal death, sustained inflammatory activation, and tissue injury often develop together and reinforce one another. Neural tissue is particularly sensitive to oxidative stress, mitochondrial dysfunction, immune-mediated inflammation, and blood-brain barrier disruption. These pathological changes are common in many forms of neural injury. Therefore, abnormal PANoptosis activation may provide a common mechanism linking different types of nervous system damage. This review summarizes the historical evolution, molecular mechanisms, disease-related roles, and intervention strategies of PANoptosis in neurological disorders. It focuses on PANoptosome assembly and key mechanistic nodes, including NOD-like receptor family pyrin domain-containing 3 (NLRP3), caspase-8, the receptor-interacting serine/threonine protein kinase 1 (RIPK1)/receptor-interacting serine/threonine protein kinase 3 (RIPK3)/mixed lineage kinase domain-like protein (MLKL) axis, gasdermin D (GSDMD), and Ninjurin 1 (NINJ1). It also highlights current translational limitations, such as disease heterogeneity, incomplete cell-specific validation, and insufficient clinical evidence.",

Single-target therapies have limited efficacy. In this study, we aimed to develop an actively targeted, multi-drug combinatorial nano-platform for coordinated intervention against ischemia/reperfusion (I/R) injury. Methods: we synthesized CX3CL1-functionalized ZIF-8 nanoparticles co-loaded with disulfiram (DFL, a GSDMD-N pore inhibitor), paquinimod (PAQ, a TLR4/NF-\u03baB inhibitor), and siNINJ1 (inhibiting membrane rupture). The nanoparticles were systematically characterized. Their neuroprotective effects and mechanisms were evaluated using a transient middle cerebral artery occlusion (tMCAO) mouse model and an oxygen-glucose deprivation/reoxygenation (OGD/R) co-culture model in vitro. Results: the nanoparticles exhibited pH-responsive release and active targeting to the ischemic penumbra. In vivo and in vitro results demonstrated that they synergistically inhibited the TLR4/NF-\u03baB/NLRP3 signaling axis and pyroptosis execution (GSDMD, caspase-1), promoted microglial polarization towards the M2 phenotype, reduced pro-inflammatory cytokines (IL-6, TNF-\u03b1), and alleviated oxidative stress and neuronal apoptosis, ultimately leading to significantly reduced infarct volume and improved neurological recovery. Conclusion: we successfully developed an \"active targeting-multi-drug synergy-cascade intervention\" nano-therapeutic platform that effectively mitigates cerebral I/R injury through multi-pathway coordination, offering a novel combinatory strategy for ischemic stroke treatment.",
        "42456380": "ID: 42456380\nTitle: Therapeutic potential of PANoptosis in calcium oxalate crystal-induced kidney injury: An integrated view of cell death pathways.\nAbstract: Calcium oxalate (CaOx) stones account for more than 80% of kidney stones and are one of the most common diseases in the urinary system. The core pathological event of CaOx crystals is the damage of renal tubular epithelial cells (RTECs). Recent studies have shown that CaOx crystals can induce a variety of programmed cell death (PCD) pathways, such as apoptosis, pyroptosis, necroptosis, and ferroptosis, in RTECs at the same time, and there are complex compensations and crosstalk between these death pathways, resulting in the limited efficacy of a single targeting strategy. Therefore, exploring the mechanisms that can integrate the regulation of multiple cell death pathways has become an important direction in this field. PANoptosis is an inflammatory PCD mode driven by the PANoptosome complex, which synchronously triggers the characteristic events of three death pathways in the same cell through the cooperative integration of the core molecular components of pyroptosis, apoptosis, and necroptosis. In this process, cysteinyl aspartate-specific proteinase-8 (Caspase-8) and receptor-interacting serine/threonine kinase 3 (RIPK3), as the core components of the PANoptosome, jointly determine whether the cell goes to a single programmed death or an integrated PANoptosis. The limited studies' evidence supports that CaOx crystals induce concurrent activation of apoptosis, pyroptosis, and necroptosis, suggesting the possibility of PANoptosis in CaOx\u2011induced kidney injury. At the same time, the rupture of the cell membrane caused by PANoptosis, similar to other forms of PCD, releases a large number of damage-associated molecular patterns (DAMPs), which activate innate immunity to form an inflammatory cascade and further aggravates tissue damage. PANoptosis, with multi-target characteristics, provides a new idea to overcome the bottleneck of single-target strategy for CaOx-induced kidney injury. In the future, new biomarkers and multi-target intervention strategies should be developed based on PANoptosis, which is expected to open up a new path for the prevention and treatment of CaOx-induced kidney injury.",

Accumulating evidence indicates that TREM2 is neither uniformly protective nor uniformly pathogenic; rather, its biological effects are highly context-dependent, governed collectively by disease stage, pathological substrates, cellular compartments, and the local microenvironment. By coupling with TYROBP/DAP12 or DAP10, TREM2 actively drives the state remodeling of pathology-associated microglia. It profoundly influences the onset and progression of neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS), as well as acute central nervous system injuries, including ischemic stroke, spinal cord injury (SCI), and traumatic brain injury (TBI). Concurrently, soluble TREM2 (sTREM2) holds significant potential not only as a biomarker but also as a context-dependent effector molecule actively participating in pathological regulation. This review synthesizes current advancements by focusing on four core themes: the structural and signaling logic of the TREM2 axis; its regulation of disease-associated microglia (DAM) remodeling; the cross-disease significance of sTREM2; and the mechanistic basis for the divergent outcomes observed with TREM2-targeted therapies across different experimental models and disease stages. The objective is to elucidate the context-dependent roles of TREM2 by analyzing consensus mechanisms, sources of discrepancy, and translational implications, thereby providing a theoretical framework and strategic direction for more precise TREM2-targeted interventions.",

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy.",

Primary microglia cells were extracted from neonatal 1-2 days C57BL/6 mice and divided into control group, Yoda1 (Piezo1 agonist) group, and Yoda1+GsMTx4 (Piezo1 inhibitor) group. Live/dead cell staining, reactive oxygen species (ROS) fluorescence staining, 5, 5', 6, 6'-tetrachloro-1, 1', 3, 3'-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) mitochondrial membrane potential detection, and transmission electron microscopy were utilized to assess microglial ferroptosis and mitochondrial functional characteristics. SPF female C57BL/6 mice aged 6 to 8 weeks were used to detect the expression of Piezo1 at different time points after SCI by Western blot, and the two time points with no significant change and the most significant change in Piezo1 expression after SCI were selected for subsequent experiments. T 8, T 9 SCI models were established by modified Allen's method, and were divided into sham operation group, injury group, and injury+shPiezo1 group (Piezo1-targeted interfering virus AAV-shPiezo1 was injected in situ to knock down the expression of Piezo1 14 days before modeling). Colocalization of Piezo1 with microglial markers purinergic receptor P2Y12 (P2ry12), and the expressions of glutathione peroxidase 4 (GPX4) and acyl coenzyme A synthetase long chain member 4 (ACSL4) were observed by immunofluorescence staining. Basso Mouse Scale (BMS) score was used to assess hindlimb motor function in mice. The level of ROS was detected by dihydroethidium (DHE) staining; the content of malondialdehyde (MDA) was detected by MDA kit; the levels of tumor necrosis factor \u03b1 (TNF-\u03b1) and interleukin 10 (IL-10) were detected by ELISA assay; the pathological morphology of spinal cord was observed by HE staining. In vitro experiments showed that compared with the control group, the Yoda1 group had typical ultrastructural changes of ferroptosis, such as increased microglial cell death, enhanced ROS fluorescence, mitochondrial membrane potential depolarization, mitochondrial shrinkage and mitochondrial cristae breakage (all P<0.05), while the GsMTx4 group could partially reverse the above effects ( P<0.05). In vivo experiments demonstrated that the expression of Piezo1 in spinal cord tissue was up-regulated sequentially after SCI, and reached the peak on the 7th day after SCI ( P<0.05), and it was mainly localized in P2ry12-positive microglia. Compared with the injury group, in the injury+shPiezo1 group, the expression of ferroptosis core protein GPX4 in microglia was increased, the expression of ACSL4 was decreased, the levels of ROS and MDA in spinal cord tissue were decreased ( P<0.05), the level of pro-inflammatory factor TNF-\u03b1 was decreased, and the level of anti-inflammatory factor IL-10 was increased ( P<0.05). In addition, the BMS score was significantly higher than that of the injury group ( P<0.05) from the 14th day after operation, and the spinal cord tissue structure was relatively well preserved, and the cavity area was reduced. SCI activates the Piezo1 channel in microglia, triggering mitochondrial dysfunction and mediating cellular ferroptosis, thereby aggravating secondary neuroinflammation. Targeted inhibition of Piezo1 effectively blocks the ferroptosis process, ameliorates the immune microenvironment, and promotes tissue repair and locomotor functional recovery after SCI. \u63a2\u7a76\u673a\u68b0\u654f\u611f\u6027\u79bb\u5b50\u901a\u9053Piezo1\u5728\u810a\u9ad3\u635f\u4f24\uff08spinal cord injury\uff0cSCI\uff09\u540e\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u4e2d\u7684\u4f5c\u7528\u673a\u5236\uff0c\u5e76\u8bc4\u4f30\u6291\u5236Piezo1\u5bf9\u6539\u5584\u635f\u4f24\u5fae\u73af\u5883\u53ca\u4fc3\u8fdb\u795e\u7ecf\u529f\u80fd\u6062\u590d\u7684\u5f71\u54cd\u3002. \u63d0\u53d6\u65b0\u751f1\uff5e2 d C57BL/6\u5c0f\u9f20\u539f\u4ee3\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001Yoda1\uff08Piezo1\u6fc0\u52a8\u5242\uff09\u7ec4\u53caYoda1+GsMTx4\uff08Piezo1\u6291\u5236\u5242\uff09\u7ec4\u3002\u5229\u7528\u6d3b\u6b7b\u7ec6\u80de\u67d3\u8272\u3001\u6d3b\u6027\u6c27\uff08reactive oxygen species\uff0cROS\uff09\u8367\u5149\u67d3\u8272\u30015\uff0c5\u2019\uff0c6\uff0c6\u2019-\u56db\u6c2f-1\uff0c1\u2019\uff0c3\uff0c3\u2019-\u56db\u4e59\u57fa\u82ef\u5e76\u54aa\u5511\u78b3\u82b1\u9752\u7898\u5316\u7269\uff085\uff0c5\u2019\uff0c6\uff0c6\u2019-tetrachloro-1\uff0c1\u2019\uff0c3\uff0c3\u2019-tetraethylbenzimidazolylcarbocyanine iodide\uff0cJC-1\uff09\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u68c0\u6d4b\u53ca\u900f\u5c04\u7535\u955c\u89c2\u5bdf\u5c0f\u80f6\u8d28\u7ec6\u80de\u94c1\u6b7b\u4ea1\u53ca\u7ebf\u7c92\u4f53\u529f\u80fd\u7279\u5f81\u3002\u53d66\uff5e8\u5468\u9f84SPF\u7ea7\u96cc\u6027C57BL/6\u5c0f\u9f20\uff0c\u91c7\u7528Western blot\u68c0\u6d4bPiezo1\u5728SCI\u540e\u4e0d\u540c\u65f6\u95f4\u70b9\u7684\u8868\u8fbe\u89c4\u5f8b\uff0c\u9009\u53d6\u635f\u4f24\u540ePiezo1\u8868\u8fbe\u672a\u89c1\u660e\u663e\u6539\u53d8\u53ca\u53d8\u5316\u6700\u663e\u8457\u76842\u4e2a\u65f6\u95f4\u70b9\u8fdb\u884c\u540e\u7eed\u5b9e\u9a8c\u3002\u91c7\u7528\u6539\u826fAllen\u6cd5\u5236\u5907T 8\u3001T 9 SCI\u6a21\u578b\uff1b\u5b9e\u9a8c\u5206\u4e3a\u5047\u624b\u672f\u7ec4\u3001\u635f\u4f24\u7ec4\u548c\u635f\u4f24+shPiezo1\u7ec4\uff08\u9020\u6a21\u524d14 d\u539f\u4f4d\u6ce8\u5c04\u9776\u5411Piezo1\u7684\u5e72\u6270\u75c5\u6bd2AAV-shPiezo1\u4ee5\u6572\u4f4ePiezo1\u8868\u8fbe\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u89c2\u5bdfPiezo1\u4e0e\u5c0f\u80f6\u8d28\u7ec6\u80de\u6807\u5fd7\u7269\u560c\u5464\u80fd\u53d7\u4f53P2Y12\uff08purinergic receptor P2Y12\uff0cP2ry12\uff09\u7684\u5171\u5b9a\u4f4d\u53ca\u8c37\u80f1\u7518\u80bd\u8fc7\u6c27\u5316\u7269\u91764\uff08glutathione peroxidase 4\uff0cGPX4\uff09\u3001\u9170\u57fa\u8f85\u9176A\u5408\u6210\u9176\u957f\u94fe\u5bb6\u65cf\u6210\u54584\uff08acyl coenzyme A synthetase long chain member 4\uff0cACSL4\uff09\u7684\u8868\u8fbe\uff1bBasso Mouse Scale\uff08BMS\uff09\u8bc4\u5206\u8bc4\u4f30\u5c0f\u9f20\u540e\u80a2\u8fd0\u52a8\u529f\u80fd\uff1b\u4e8c\u6c22\u4e59\u952d\uff08dihydroethidium\uff0cDHE\uff09\u67d3\u8272\u68c0\u6d4b\u7ec4\u7ec7ROS\u6c34\u5e73\uff1b\u4e19\u4e8c\u919b\uff08malondialdehyde\uff0cMDA\uff09\u8bd5\u5242\u76d2\u68c0\u6d4bMDA\u542b\u91cf\uff1bELISA\u68c0\u6d4b\u708e\u75c7\u56e0\u5b50TNF-\u03b1\u3001IL-10\u6c34\u5e73\uff1bHE\u67d3\u8272\u89c2\u5bdf\u810a\u9ad3\u7ec4\u7ec7\u75c5\u7406\u5f62\u6001\u3002. \u4f53\u5916\u5b9e\u9a8c\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cYoda1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u6b7b\u4ea1\u589e\u591a\u3001ROS\u8367\u5149\u589e\u5f3a\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u53bb\u6781\u5316\u3001\u7ebf\u7c92\u4f53\u51fa\u73b0\u76b1\u7f29\u53ca\u5d74\u65ad\u88c2\u7b49\u94c1\u6b7b\u4ea1\u5178\u578b\u8d85\u5fae\u7ed3\u6784\u6539\u53d8\uff08\u5747 P<0.05\uff09\uff1b\u800cGsMTx4\u7ec4\u53ef\u90e8\u5206\u9006\u8f6c\u4e0a\u8ff0\u6548\u5e94\uff08 P<0.05\uff09\u3002\u4f53\u5185\u5b9e\u9a8c\u793a\uff0cSCI\u540e\u810a\u9ad3\u7ec4\u7ec7\u4e2dPiezo1\u8868\u8fbe\u5448\u65f6\u5e8f\u6027\u4e0a\u8c03\uff0c\u672f\u540e7 d\u8fbe\u5cf0\u503c\uff08 P<0.05\uff09\uff0c\u4e14\u4e3b\u8981\u5b9a\u4f4d\u4e8eP2ry12\u9633\u6027\u5c0f\u80f6\u8d28\u7ec6\u80de\u3002\u4e0e\u635f\u4f24\u7ec4\u6bd4\u8f83\uff0c\u635f\u4f24+shPiezo1\u7ec4\u5c0f\u80f6\u8d28\u7ec6\u80de\u5185\u94c1\u6b7b\u4ea1\u6838\u5fc3\u86cb\u767dGPX4\u8868\u8fbe\u56de\u5347\u3001ACSL4\u8868\u8fbe\u4e0b\u964d\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5185ROS\u53caMDA\u6c34\u5e73\u964d\u4f4e\uff08 P<0.05\uff09\uff0c\u540c\u65f6\u4fc3\u708e\u56e0\u5b50TNF-\u03b1\u6c34\u5e73\u4e0b\u964d\u3001\u6297\u708e\u56e0\u5b50IL-10\u6c34\u5e73\u5347\u9ad8\uff08 P<0.05\uff09\uff1b\u6b64\u5916\uff0c\u81ea\u672f\u540e14 d\u8d77BMS\u8bc4\u5206\u663e\u8457\u9ad8\u4e8e\u635f\u4f24\u7ec4\uff08 P<0.05\uff09\uff0c\u4e14\u810a\u9ad3\u7ec4\u7ec7\u7ed3\u6784\u4fdd\u5b58\u76f8\u5bf9\u5b8c\u597d\uff0c\u7a7a\u6d1e\u9762\u79ef\u51cf\u5c0f\u3002.

        "42468577": "ID: 42468577\nTitle: Targeting neuroinflammation and neurodegeneration in Parkinson's disease: Emerging natural and synthetic therapeutic strategies.\nAbstract: Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder worldwide. It is associated with the ongoing degeneration of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies that contain \u03b1-synuclein. These pathological changes lead to abnormalities of motor symptoms (tremor, rigidity, bradykinesia) and non-motor symptoms (cognitive decline, sleep abnormalities, psychiatric abnormalities). The pathogenesis of PD is complex and multifactorial, involving interconnected mechanisms such as oxidative stress, mitochondrial dysfunction, neuroinflammation, impaired autophagy, ferroptosis, and genetic factors. To develop effective therapeutic interventions, these pathways need to be understood. Current treatments, such as levodopa and deep-brain stimulation (DBS), are symptom-based and do not break disease progression. Thus, considerable research efforts have been geared towards finding disease-modifying therapeutic strategies. Natural bioactive compounds, gene-based therapies, stem cell-based therapies, and nanotechnology-assisted drug delivery systems are promising alternatives as suggested by recent advances. Antioxidant compounds like curcumin, resveratrol, and epigallocatechin gallate (EGCG) show promising antioxidant and neuroprotective effects, and nanomedicine provides boosted delivery to the brain and targeted drug distribution. In future clinical applications, these new strategies could help to more effectively and permanently manage PD.",

However, the mechanism of myocardial PANoptosis in myocardial ischemia-reperfusion (MI/R) remains unclear. Allicin is a promising drug for MI/R treatment, and the targets for myocardial PANoptosis remain to be explored. This study aims to clarify the mechanism of myocardial PANoptosis during MI/R and therapeutic targets of allicin. Sprague-Dawley rats were used to establish MI/R models. Allicin (3.6\u202fmg/kg) was injected via the tail vein 5\u202fmin before reperfusion. Myocardial damage (cardiac function, structure, cTnT, CK-MB and apoptosis), PANoptosome components (RIPK1/3, caspase-8, ASC and NLRP3), PANoptosis indicators (MLKL, GSDMD, IL-1\u03b2/18 and caspase-3) were assessed to evaluate the cardioprotective effects of allicin. Subsequently, the potential signaling pathway related to PANoptosis and therapeutic targets of allicin were screened through transcriptomic analysis, and TLR4 signaling was selected for verification. Then, H9C2 cells were used to establish an oxygen-glucose deprivation/reperfusion (OGD/R) model. The TLR4 inhibitor TAK-242, agonist RS09, and allicin were used to clarify the pathological role of TLR4 in myocardial PANoptosis and the therapeutic target of allicin by measuring the indicators of myocardial damage, PANoptosis and TLR4 expression. In vivo experiments revealed that allicin alleviated MI/R injury and reduced both myocardial PANoptosome components and PANoptosis. Based on transcriptomic analysis and published studies, the TLR4 signaling pathway was selected to verify the pathological role in PANoptosis and the therapeutic effects of allicin. In vitro experiments demonstrated that TLR4 activation further aggravated OGD/R-induced PANoptosis and increased TLR4 expression. Conversely, both allicin and the TLR4 inhibitor suppressed myocardial PANoptosis and TLR4 expression. Allicin can reduce myocardial PANoptosis and ameliorate MI/R injury by inhibiting TLR4 activation. These findings provide a new target and strategy for the treatment of MI/R injury.",
        "42474555": "ID: 42474555\nTitle: Neural network-enhanced investigation of ferroptosis and druggability in early-onset alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder which is multifactorial in nature. Some of its characteristics are slow cognitive decline, memory problems and behavioral changes. AD patient brains show a progressive synaptic toxicity, autophagy, neuroinflammation, excess generation of reactive oxygen species (ROS), neuronal death and oxidative stress, which occurs due to disrupted metal homeostasis along with tau and amyloid-\u03b2 protein deposition. Notably, lipid peroxidation, iron buildup and elevated oxidative stress in AD brains suggest a possible molecular\u00a0connection between ferroptosis and AD neurodegeneration. This study explores the genetic and bioinformatics perspective on the relationship between ferroptosis and AD aiming to identify potential therapeutic potential biomarkers using Neural network (NN) and Machine learning models. Six ferroptosis related genes were found to be differentially expressed in AD. Further machine learning analysis shortlisted four key biomarker genes. An NN-based diagnostic prediction model was developed and validated using AUC-ROC anaysis, which gave high diagnostic values (AUC- 0.92) in the analysis. The findings highlight a strong correlation between ferroptosis and altered metabolic functions in AD. miRNA-gene interaction analysis revealed that two biomarker genes, CYBB and ACSL4 can be regulated by several regulatory miRNAs i.e., hsa-miR-146-5p, hsa-miR-106b-5p, hsa-miR-223-3p, hsa-miR-155-5p, hsa-miR-34a-5p, hsa-miR-125b-5p and hsa-miR-27a-3p suggesting their potential as early diagnostic potential biomarkers. Immune microenvironment analysis revealed strong neuroinflammatory responses in AD with increased infiltration of macrophages (M0, M1 and M2), monocytes and multiple T cell subsets. This heightened immune activity may be driven by ferroptosis-induced oxidative stress contributing to neuronal death. Furthermore, druggability of these targets was evaluated and several drugs were identified that may be potentially repurposed for therapeutic intervention in AD pathogenesis. This study presents a diagnostic predictive model integrating gene expression, miRNA regulation and immune infiltration analysis, offering a novel perspective on early AD detection. The identified ferroptosis-related potential biomarkers and regulatory miRNAs could serve as valuable tools for clinical diagnosis and targeted therapeutic intervention, advancing personalized treatment strategies for Alzheimer's disease.",
        "42476817": "ID: 42476817\nTitle: Functional divergence of Capicua isoforms explains differential tissue vulnerability in neurological disease.\nAbstract: Many neurological diseases impact specific brain regions despite widespread expression of the disease-related protein. Spinocerebellar ataxia type 1 (SCA1) primarily affects the cerebellum, though Ataxin-1 (ATXN1) is widely expressed. We previously showed that intensified interaction between mutant ATXN1 and Capicua (CIC) drives SCA1 pathogenesis in the cerebellum, whereas ATXN1 loss augments amyloid \u03b2 production in the hippocampus and cortex. CIC, however, forms a complex with ATXN1 and its paralog, Ataxin-1-like (ATXN1L), yet knockout of either yields completely different phenotypes. To determine whether this could be due to CIC having two isoforms, we generated mice bearing either the long (CIC-L) or short (CIC-S) isoform. Loss of CIC-L led to cognitive deficits, whereas loss of CIC-S caused early postnatal lethality, phenocopying ATXN1 and ATXN1L knockout mice, respectively. Furthermore, CIC-L preferentially interacts with ATXN1, and CIC-S with ATXN1L. Our data underscore the importance of isoform-paralog interplay in studying regional vulnerability in neurodegenerative diseases.",

By binding to various cell membrane receptors, A\u03b2Os can trigger abnormal intracellular signaling transduction, leading to neuronal damage. This article systematically summarizes the interaction mechanisms of nearly ten A\u03b2O-binding receptors and focuses on reviewing recent therapeutic strategies aimed at neuroprotection through interventions in A\u03b2O-receptor interactions or by blocking/modulating relevant receptor signaling pathways. The discussed content provides a molecular theoretical foundation and research perspectives for the rational design of anti-AD drugs targeting A\u03b2O receptors.",

This study aimed to identify and validate the molecular targets, signaling pathways, and mechanisms by which Betulinic acid (BA) exerts its therapeutic effects on SCI, providing new directions for clinical intervention. In vivo, Kunming mice underwent behavioral tests, Nissl staining, and Hematoxylin-eosin staining to evaluate motor function recovery and determine the expression levels of relevant biomarkers. Bioinformatics analyses were employed to investigate the genes involved in the SCI-BA interaction, elucidating key signaling pathways, followed by molecular docking of potential target genes. In vitro, lipopolysaccharide was used to induce a secondary SCI condition in cultured astrocytes, enabling the evaluation of BA's effects on inflammatory and apoptotic responses. The results demonstrated that BA could significantly promote motor function recovery and reduce the expression levels of inflammation-related cytokines, including IL-1\u03b2, IL-6, and TNF-\u03b1, in SCI mice. Through bioinformatics analysis, Myc was identified as a key target of BA in SCI, and NF-\u03baB and apoptosis pathways could be implicated in its mechanism of action. Both in vitro and in vivo experiments confirmed that BA could target Myc to modulate the inflammatory response in astrocytes, reducing the activation of RELA and MAPK14. In conclusion, these findings indicate that BA attenuates neuroinflammation and apoptosis via Myc and the NF-\u03baB signaling pathway, thereby promoting functional recovery following SCI.",
        "42479245": "ID: 42479245\nTitle: Seipin modulates Alzheimer's disease pathogenesis by regulating ferroptosis through a glycine-mediated metabolic pathway.\nAbstract: Alzheimer's disease (AD) remains an incurable neurodegenerative disorder with an elusive pathogenesis, where emerging evidence implicates metabolic dysregulation and ferroptosis in neuronal loss. Although the BSCL2 gene, which encodes Seipin, is crucial for lipid metabolism, its specific role in the progression of AD remains undefined. This study employed Mendelian randomization (MR) analysis, in vivo APP/PS1 mouse models, and in vitro BV2 microglial assays to elucidate the mechanistic axis linking BSCL2, metabolites, and ferroptosis in AD. MR analysis demonstrated a causal relationship between genetically predicted elevated BSCL2 expression and an increased risk of AD, partially mediated by glycine. Supporting these genetic findings, stereotactic knockdown of Seipin in the hippocampus of APP/PS1 mice significantly ameliorated cognitive deficits without inducing systemic metabolic toxicity. Mechanistically, Seipin deficiency reduced ferroptosis in both AD mouse brains and A\u03b2-stimulated microglia, as evidenced by the upregulation of anti-ferroptotic markers (GPX4, Nrf2, HO-1) and the suppression of pro-ferroptotic effectors (ACSL4, NCOA4). Moreover, glycine supplementation partially ameliorated the aggravated ferroptotic phenotype caused by Seipin overexpression, indicating a functional feedback mechanism in which glycine facilitates glutathione synthesis to mitigate Seipin-induced lipid peroxidation. These findings collectively identify Seipin as a novel regulator of ferroptosis in the pathogenesis of AD and underscore the potential of the BSCL2-glycine-ferroptosis axis as a therapeutic target. Future research should aim to elucidate the specific molecular interactions between Seipin and the iron-handling machinery and to validate glycine-based interventions in clinical settings as a means to prevent neurodegeneration.",

Herein, we report a dual-function PROTAC, dACSL4, and its nose-to-brain delivery for brain-preferred protein degradation and therapeutic suppression of ferroptosis in neurodegeneration. dACSL4 selectively degrades acyl-CoA synthetase long-chain family member 4 (ACSL4) while concurrently activating peroxisome proliferator-activated receptor \u03b3 (PPAR\u03b3), thereby coordinating lipid metabolism and oxidative stress to suppress neuronal ferroptosis. dACSL4 achieved up to 30-fold greater protection against neuronal ferroptosis compared to conventional ferroptosis inhibitors. Intranasal delivery of dACSL4 using biodegradable lipid nanoparticles (BAmP-TK12) enabled brain-preferred ACSL4 degradation and PPAR\u03b3 activation, reducing lipid peroxidation and preserving dopaminergic neurons in a Parkinson's disease model, ultimately improving motor function. Our findings establish a modular strategy for brain-preferred protein degradation and highlight the therapeutic potential of dual-function degraders for ferroptosis suppression in neurodegenerative diseases.",
        "42481419": "ID: 42481419\nTitle: Isoform-paralog specificity and tissue-dependent vulnerabilities in neurological disorders.\nAbstract: A long-standing observation in studies of neurological disorders is that broadly expressed disease genes can cause dysfunctions that are limited to certain brain regions or cell types. In this issue of Genes & Development, Lee et al. (doi:10.1101/gad.353596.125) address the mystery of this selective vulnerability by studying ATXN1-CIC interactions implicated in spinocerebellar ataxia type 1. They provide compelling evidence that specific ATXN1 paralogs preferentially interact with specific CIC isoforms tissue-dependently. Whereas ATXN1-CIC-L complexes regulate hippocampal gene expression and learning, ATXN1L-CIC-S complexes regulate lung alveolarization, postnatal survival, and hydrocephalus risk. This work thus demonstrates the potential contribution of isoform-paralog specificity to tissue-specific vulnerabilities in neurological disorders.",

Spinal cord injury (SCI) results in abnormalities in astrocytic cholesterol metabolism and excessive oxysterol accumulation, contributing to the activation of inflammation. However, the relevant regulatory mechanism involved in aberrant cholesterol metabolism by astrocytes has not been fully elucidated. In the present study, we demonstrated that SCI-induced D-DT protein levels increased synchronously with CH25H expression. Administration of the D-DT inhibitor 4-CPPC markedly decreased CH25H expression in astrocytes following SCI. D-DT facilitates CH25H production in astrocytes by activating the intracellular ERK/NF-\u03baB pathway through binding to the CD74 receptor. Conditioned culture medium from astrocytes following the knockdown of astrocyte CH25H expression by siRNA reduced microglial migration. The inhibition of D-DT or CH25H activity reduces microglia/macrophage accumulation at the lesion site and improves motor functional recovery following SCI. Our results reveal a novel function of D-DT-mediated astrocytic CH25H activation, which modulates pathological microenvironments through the activation of inflammation. These data may provide a potential therapeutic strategy for CNS inflammation-associated diseases.",

While pharmacological, psychological, and physiotherapeutic approaches have been applied, including whole-body vibration (WBV), synaptic-level mechanisms of WBV remain largely unexplored. Here, we assessed the post-SCI pain-associated behavior index (PAB, based on established behavioral criteria) and compared synapse counts (SYN+, VGLUT1+, ChAT+, VGAT+), CGRP+- and SER+-structures, as well as astrocytic and microglial populations in the lumbar dorsal horn following thoracic SCI in WBV-treated and untreated rats. Animals received WBV from postoperative week 3 to 12, and outcomes were compared with non-treated controls. PAB was consistently reduced in WBV-treated animals. STED-microscopy quantification showed that WBV increased the linear density of VGAT\u2009+\u2009and VGLUT1\u2009+\u2009perisomatic terminals, as well as the number of SER\u2009+\u2009fibers. Conversely, WBV reduced CGRP\u2009+\u2009structures in the dorsal horn, decreased the density of CGRP\u2009+\u2009perisomatic and axo-axonic synapses, and lowered astrocytic and microglial populations. Our data indicate that the WBV-induced frequent (15-30\u2005Hz) muscle contractions and proprioceptive impulses contribute to spasticity modulation (via VGAT-related mechanisms) and attenuation of post-SCI hyperalgesia (CGRP-associated). Together with the reduced astro- and microglia amounts, the described synaptic alterations are considered essential prerequisites for better motor recovery. These findings provide preclinical evidence for the functional benefits of WBV in an animal SCI model and warrant further investigations to determine mechanisms underpinning this non-invasive, low-cost and easily applicable rehabilitation approach.",

It is increasingly recognized as a contributor to liver cell injury. Stearoyl-CoA desaturase 1 (SCD1) is a rate-limiting enzyme in monounsaturated fatty acid synthesis. It plays a key role in maintaining lipid homeostasis and may affect cellular susceptibility to ferroptosis. However, it remains unclear whether SCD1 restrains ferroptosis-associated injury in chicken embryonic liver (CEL) cells. Therefore, this study aimed to investigate the role of SCD1 in regulating ferroptosis susceptibility and cellular injury related to ferroptosis in CEL cells, with a focus on its effects on lipid metabolism, oxidative stress, and iron homeostasis. The results showed that SCD1 knockdown reduced intracellular lipid droplet area, triglyceride, and total cholesterol levels in CEL cells (P < 0.05). In addition, SCD1 knockdown induced mitochondrial ultrastructural changes associated with ferroptosis, including mitochondrial shrinkage, increased membrane density, and cristae disruption. It also aggravated oxidative stress, as shown by increased reactive oxygen species, oxidized glutathione, and malondialdehyde levels and decreased glutathione content (P < 0.05). SCD1 knockdown reduced cell viability, whereas oleic acid or ferrostatin-1 treatment partially reversed this decrease (P < 0.05). Moreover, SCD1 knockdown increased ACSL4 expression and decreased SLC7A11, GPX4, and Nrf2 expression at both the mRNA and protein levels (P < 0.05). SCD1 knockdown further reduced mitochondrial membrane potential and increased lipid peroxidation, intracellular Fe\u00b2\u207a levels, and total iron content (P < 0.05). In contrast, SCD1 overexpression increased lipid accumulation, reduced reactive oxygen species levels, increased glutathione content, increased SLC7A11, GPX4, and Nrf2 expression, and decreased ACSL4 protein expression (P < 0.05) without significantly affecting ACSL4 mRNA expression. These findings suggest that SCD1 regulates the susceptibility of CEL cells to ferroptosis and exerts a protective effect by improving lipid metabolism, antioxidant defenses, and mitochondrial function, indicating that SCD1 is a key regulatory factor in maintaining the homeostasis and health of chicken liver.",
        "42486345": "ID: 42486345\nTitle: Novel role of GADD45A in synergistic regulation of neuronal ferroptosis and apoptosis after spinal cord injury via NF-\u03baB signaling.\nAbstract: Ferroptosis and apoptosis are major mechanisms of neuronal injury after spinal cord injury (SCI), but regulators that coordinate both processes remain poorly defined. In this study, we analyzed 188 ferroptosis-related differentially expressed genes (FRDEGs) at 7\u00a0day (7d) after SCI and identified GADD45A as a central gene in the post-SCI ferroptosis network, with a functional profile closely linked to apoptosis. GADD45A was markedly upregulated in injured spinal cord tissue. In vivo, GADD45A knockdown improved neurological recovery and promoted tissue repair by modulating markers of ferroptosis and apoptosis. In H2O2-treated PC12 cells, GADD45A knockdown reduced the expression of Cleaved Caspase-3, BAX, Cleaved Caspase-9, 4-HNE, and ACSL4, while increasing the expression of BCL-2, GPX4, FTH1, and FPN. It also attenuated H2O2-induced cellular injury. Mechanistically, GADD45A knockdown inhibited NF-\u03baB signaling and reduced nuclear translocation of NF-\u03baB-p65. These protective effects were reversed by the NF-\u03baB activator CU-T12-9. Collectively, these findings suggest that GADD45A promotes neuronal ferroptosis and apoptosis after SCI by regulating the NF-\u03baB pathway, and that GADD45A may be a potential therapeutic target for SCI.",

Interleukin-6 (IL-6) is an early and critical inflammatory mediator observed in lesions post-SCI. Antagonizing the signaling pathway presents a promising strategy to mitigate early inflammation and secondary injury after trauma. Here, we identified specific activation of the IL-6 receptor in neurons and microglia in lesions, indicating their responsiveness to early up-regulated IL-6 signaling within the microenvironment. In\u00a0vitro, neutralizing IL-6 signaling in microglia effectively alleviated their inhibitory effects on neuronal axon growth in conditioned media. Building on this, we developed a reactive-oxygen-species-responsive hydrogel for the sustained local delivery of tocilizumab, an IL-6 receptor antagonist, and implanted it in a complete transection SCI model. In\u00a0vivo, sustained IL-6 receptor blockade effectively reduced early inflammatory cell infiltration, modulated microglial polarization toward an anti-inflammatory phenotype, and fostered neuronal regeneration within the lesion. Importantly, this therapeutic intervention promoted long-term hind limb functional recovery in SCI mice. This study underscores the therapeutic potential of precisely targeting early inflammatory cytokine signaling pathways, particularly IL-6, to improve outcomes after SCI.",
        "42490372": "ID: 42490372\nTitle: Conformational diversity and interaction signatures of NADH across protein families.\nAbstract: Nicotinamide adenine dinucleotide (NADH) is a ubiquitous redox cofactor that participates in a wide range of enzymatic and regulatory processes. These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors.",

This review systematically delineates the molecular architecture and translational trajectories underlying metal-dependent RCD, including iron-driven ferroptosis, copper-mediated cuproptosis, and additional emerging modalities such as calcicoptosis, necrosis by sodium overload (NECSO), and the newly designated zincoptosis, mnoptosis, and coptosis. We examined distinct execution mechanisms, ranging from membrane lipid peroxidation and lipoylation-targeted proteotoxic stress to organelle-specific bioenergetic failure, which arise following disruption of compartmentalized metal-buffering networks. To bridge the persistent knowledge gap between foundational metallobiology and clinical application, we evaluated a bidirectional therapeutic framework: exploiting synthetic lethality and metabolic gating via clinical inducers (e.g., sorafenib, elesclomol) to selectively eliminate therapy-resistant malignancies while deploying targeted pathway inhibitors and systemic agonists (e.g., dipyridamole, omaveloxolone) to limit pathological tissue degeneration in ischemic and neurodegenerative disorders. Recognizing that off-target multiorgan toxicity and complex in vivo crosstalk among interconnected death pathways (e.g., disulfidptosis and PANoptosis) represent major translational challenges, we assessed advanced materials-science strategies designed to overcome these barriers. Specifically, we highlighted the integration of single-atom catalysts, stimuli-responsive nanomedicines, and biomimetic carriers engineered to spatiotemporally confine catalytic oxidative flux. Finally, we examined the systemic immunological consequences of targeted metal dysregulation, detailing how metal-induced immunogenic cell death and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway hyperactivation reshape immunosuppressive microenvironments and modulate sterile inflammation, thereby enhancing responsiveness to immune checkpoint blockade, providing a definitive molecular blueprint for next-generation precision therapeutics.",

Conductive nanocomposite hydrogels have emerged as a transformative class of immuno-engineered biomaterials designed to actively overcome these barriers. Beyond providing electroactive scaffolds to restore neural signaling, these advanced platforms integrate functional nanomaterials (e.g., carbon-based, MXene, and conductive polymers) within biocompatible polymer networks to facilitate targeted immunomodulation. Their core scientific significance lies in their synergistic capacity to simultaneously scavenge pathological reactive oxygen species (ROS) and steer macrophage polarization towards a pro-regenerative phenotype, thereby reprogramming the inhibitory injury niche into a permissive, pro-healing milieu. This review systematically elucidates the design principles spanning crosslinking strategies to nanomaterial selection that underpin these dual functions. We critically summarize recent breakthroughs in applying these multifunctional hydrogels to treat spinal cord injury, traumatic brain injury, stroke, and peripheral nerve defects, where they demonstrate enhanced functional recovery. By bridging the fields of conductive biomaterials and immunomodulation, this work not only surveys the state-of-the-art but also provides a unified framework for developing next-generation therapeutic platforms that couple bioelectronic cues with precise immune modulation, offering a novel paradigm for neural regeneration medicine.",

This study was conducted as a systematic and bibliometric literature review following the PRISMA 2020 logic of identification, screening, eligibility, and inclusion. Searches were performed in Web of Science, Scopus, and PubMed for studies published in English between 2020 and 2025. The search strategy combined terms related to glaucoma or ocular neurodegeneration, the glutamatergic axis, and biomarkers, mechanisms, or interventions. After screening and full-text assessment, 39 studies were included in the systematic synthesis. Due to methodological heterogeneity, the evidence was synthesized narratively and comparatively, without meta-analysis. The included studies were organized into six thematic clusters: metabolomic, transcriptomic, and diagnostic biomarkers; pharmacological and neuroprotective interventions; nutritional, antioxidant, and natural-compound neuroprotection; oxidative stress, mitochondrial dysfunction, and regulated cell death; neuroinflammation and glia-mediated retinal injury; and glutamatergic excitotoxicity and neurotransmitter imbalance. The evidence indicates that glutamate-related mechanisms in glaucoma are mainly associated with endogenous glutamatergic metabolism, excitotoxicity, impaired glutamate clearance, glutamate-glutamine homeostasis, oxidative and nitrosative stress, mitochondrial dysfunction, ferroptosis, neuroinflammation, and retinal ganglion cell vulnerability. None of the 39 included studies directly evaluated dietary glutamate or monosodium glutamate as the main exposure. The available evidence does not support a direct conclusion that dietary glutamate or MSG intake contributes to glaucoma onset or progression. Instead, current findings mainly support an indirect mechanistic relationship between endogenous glutamatergic dysregulation and glaucomatous neurodegeneration. Pharmacological, antioxidant, metabolic, and natural-compound strategies show neuroprotective potential, particularly in experimental models, but clinical and translational studies are still needed to clarify the role of dietary exposure, glutamate-glutamine metabolism, and targeted neuroprotective interventions in glaucoma.",

To investigate the overall changes in m1A levels following SCI, we analyzed transcriptomic sequencing data from SCI samples and assigned m1A scores based on the levels of m1A regulatory factors. In this study, the m1A score is an inferred proxy calculated from the expression of m1A regulator genes (writers/erasers/readers). It does not directly measure RNA m1A modification levels. Our results show that the m1A score increased within the first day after SCI and then decreased, falling below baseline by day 3 and day 7. Further analysis revealed that microglia and neurons are the two cell types with the most significant changes in the m1A score. In microglia, m1A score decreased at all time points, whereas in neurons, m1A score increased at all time points. Additionally, through pseudotime analysis and function enrichment analysis, the m1A score may be associated with the phenotypic transition of microglia and neuronal energy metabolism, and this was further validated by conducting studies both in vivo and in vitro. In a word, our study unveils the characteristic changes of m1A at both the bulk and single-cell levels following SCI, and suggests potential links to neuronal function and supports the rationale for further studies exploring m1A-related regulators as therapeutic targets in SCI.",

While microglial lipid metabolic reprogramming, particularly lipid droplet accumulation, has been implicated in chronic inflammation, the underlying mechanisms remain poorly understood. Using single-cell transcriptomics, we identified a previously defined lipid droplet-accumulating microglia (LDAM) subpopulation in spinal cord injury (SCI), characterized by elevated PLIN2 expression. Genetic deletion of Plin2 markedly reduced lipid droplet burden, attenuated neuroinflammation, and promoted neuronal survival and functional recovery in vivo. Mechanistically, PLIN2 interacts with the mitochondrial outer membrane protein PGAM5 to regulate lipid droplet-mitochondria contacts. This interaction inverts canonical metabolic flux by redirecting fatty acids from mitochondria back to lipid droplets, thereby suppressing \u03b2-oxidation and inducing mitochondrial dysfunction, which subsequently triggers STING-dependent inflammation. Notably, the PLIN2 220-392 domain is essential for PGAM5 binding and contact formation; disrupting this interaction attenuates STING signaling and enhances neuroprotection and functional recovery in vivo. Our findings identify the PLIN2-PGAM5 as a critical metabolic-immune pathway and suggest that targeting organelle-contact-mediated metabolic reprogramming represents a potential therapeutic strategy for CNS injury.",

In this study, we aimed to identify and validate key genes associated with necroptosis in SCI using bulk RNA-seq data, followed by differential analysis and weighted gene coexpression network analysis (WGCNA). We identified several candidate necroptosis-related genes, and further least absolute shrinkage and selection operator (LASSO) regression highlighted five SCI-necroptosis differentially expressed genes (DEGs): toll-like receptor 4 (Tlr4), Nlrp3, Il1b, Tnfaip3, and Stat4. These genes were validated using RT-qPCR and western blot experiments. Our analysis revealed that necroptosis scores were significantly elevated following SCI. Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) analysis revealed that Tlr4 was upregulated in myeloid cells (microglia and macrophages) and played a pivotal role in triggering downstream necroptosis, which was confirmed by protein levels. In vitro and in vivo experiments confirmed that Tlr4 inhibition attenuated necroptosis and inflammation. This study is the first to establish Tlr4 as a direct upstream regulator of the pRIPK1/pRIPK3/pMLKL necroptotic axis in SCI, distinct from its role as a general inflammatory mediator, suggesting Tlr4 as a promising therapeutic target for functional recovery.",

Soluble triggering receptor expressed on myeloid cells 2 (sTREM2) and chitinase-3-like protein 1 (YKL-40) are fluid biomarkers of microglial and astrocytic reactivity associated with AD progression. However, their coupling to amyloid and tau pathology, stage-specific roles, and prognostic utility remain unclear. This systematic review synthesized evidence from 2021 to 2025 on associations of sTREM2 and YKL-40 with AD progression. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. PubMed/Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Institute of Electrical and Electronics Engineers (IEEE) Xplore, and Web of Science were searched (Jan 2021-Dec 2025), with citation searching. Duplicates were removed using EndNote X21 (Clarivate, London, UK). Two independent reviewers screened records using the Population, Intervention, Comparison, Outcomes, and Study Design (PICOS) criteria, with disagreements resolved by a third reviewer. Original human studies measuring sTREM2 and/or YKL-40 across the AD spectrum were included. Methodological quality was assessed using the Newcastle-Ottawa Scale (NOS). Due to heterogeneity in study design and outcomes, a narrative synthesis was performed. Thirteen studies were included: seven on sTREM2, five on YKL-40, and one on both. Six were low risk of bias, and seven were moderate. Cerebrospinal fluid (CSF) sTREM2 showed a biphasic pattern across disease stages, with early potential neuroprotective associations and later correlation with cortical atrophy and cognitive decline. A sex-APOE \u03b54 interaction was observed, with higher levels in female carriers. YKL-40 showed weak amyloid associations but strong coupling with tau pathology and neurodegeneration, influenced by vascular risk factors. Plasma YKL-40 predicted incident dementia and cognitive decline, and serum YKL-40 differentiated early dementia from controls with good diagnostic performance. sTREM2 and YKL-40 represent biologically distinct but complementary neuroinflammatory pathways in AD. sTREM2 reflects a stage-dependent microglial response, while YKL-40 reflects tau-associated astrocytic activation modulated by vascular factors. Longitudinal studies with concurrent biomarker assessment are needed to clarify their combined prognostic value.",

Current biomaterial-based interventions often fail to address the dual need for acute inflammation control and long-term immune tolerance. Herein, we present a multifunctional Sr-Zn mesoporous bioactive glass (MBG) system that enables spatiotemporal immunoreprogramming. Rapamycin (Ra) is first loaded into MBG pores to induce Treg differentiation via mTOR inhibition. STING inhibitor H-151 is then adsorbed onto a polydopamine (PDA) coating for early suppression of cGAS-STING signaling. Finally, a CCL22-mimetic peptide is grafted for CCR4-mediated Treg recruitment. Meanwhile, sustained Sr2+/Zn2+ release provides bioactive ionic cues that support immune remodeling and neural repair. This sequential design first polarizes microglia/macrophages toward an anti-inflammatory M2 phenotype and then enriches Tregs to sustain an immunosuppressive niche, while concurrently facilitating neuroregenerative remodeling. In vitro, the system regulates STING and mTOR pathways, induces Treg generation, and enhances neural stem cell differentiation and neuronal outgrowth. In a mouse SCI model, the injectable MBG-hydrogel hybrid reduces lesion volume, promotes remyelination, axonal regrowth, and motor function. Treg depletion or CCR4 blockade abrogates therapeutic benefits, confirming the role of adaptive immunity. This study offers a dual-arm immunoengineering strategy that couples innate suppression and adaptive tolerance, opening new avenues for CNS regeneration.",

Increasing evidence indicates that regulated cell death (RCD) can act as an upstream amplifier in selected autoimmune settings, while in other settings it may mainly report downstream collateral injury caused by cytotoxic lymphocytes, immune complexes, complement activation, or tissue hypoxia. Accordingly, this review distinguishes causal death execution from associative pathway signatures and highlights the types of longitudinal, cell-type-resolved, and perturbational evidence needed to make that distinction. We summarize how apoptosis, necroptosis, pyroptosis, and ferroptosis operate as an interlocking network in autoimmune microenvironments, frequently co-existing as context-dependent mixed-death states driven by shared triggers such as cytokines, PRR ligands, and oxidative stress, and governed by decision hubs including RIPK1 and caspase-8. We highlight integrated concepts such as PANoptosis to explain pathway convergence and compensatory switching into parallel lytic branches when a single node is constrained. The review further connects mechanistic insights to translational priorities, emphasizing biomarker strategies that report pathway engagement, targeted modulation of executors or upstream sensing and cytokine circuits, and lesion-localized delivery approaches to improve the therapeutic window. Finally, we outline key gaps that must be addressed to enable precision interventions, including spatial and cell-type resolved validation of death programs, longitudinal profiling across flare-remission trajectories, and harmonized composite panels capable of capturing mixed-death dynamics in heterogeneous AIDs.",

Macrophages regulate neuroinflammation and ECM remodelling in ASCI. Studies shown ECM related gene Lgals3 regulate macrophage polarization across various diseases. However, the role of Lgals3 in ASCI-related ECM remodelling and neuroinflammation remains unclear. We integrated Single-cell RNA Sequencing (ScRNA-seq) analysis with in vitro and in vivo experiments. An ECM-related gene set was constructed for bioinformatic analyses of cell clustering, pseudotime trajectory, cell-cell communication, and transcription factor activity. LPS+IFN-\u03b3-induced RAW264.7 macrophages were treated with the Lgals3 inhibitor GB1107, and the Lgals3/NF-\u03baB/p65/Ccl2 axis was further dissected by siRNA-mediated Lgals3 knockdown, pharmacological NF-\u03baB inhibition with QNZ, and TNF-\u03b1-mediated NF-\u03baB reactivation rescue. ASCI models in SD rats were assessed via multiplex immunohistochemistry (mIHC), histology, TUNEL, western blot, and qRT-PCR. Seven cell types were identified in the ASCI microenvironment, with macrophages showing the most upregulated ECM-related genes. Four ECM-associated macrophage subtypes were defined; Lgals3high macrophages (Mac-1), characterized by high Lgals3 and Ccl2 expression, dominated early-phase ASCI. Mac-1 exhibited the strongest intercellular communication with prominent CCL signalling pathway activation. Lgals3, Ccl2, and p65 were specifically upregulated in M1 macrophages post-ASCI, with p65 nuclear translocation. GB1107 inhibited NF-\u03baB, promoted M1-to-M2 polarization, reduced inflammatory infiltration and ECM remodelling, and decreased apoptosis. Mechanistically, siRNA-mediated Lgals3 silencing suppressed NF-\u03baB/p65 activation and Ccl2 expression while inducing Arg1; this phenotype was recapitulated by NF-\u03baB inhibition and reversed by TNF-\u03b1-driven NF-\u03baB reactivation, validating the Lgals3/NF-\u03baB/p65/Ccl2 axis as the obligate regulatory backbone of macrophage polarization. Lgals3high macrophages are core drivers of ECM remodelling in ASCI via a Lgals3/NF-\u03baB/p65/Ccl2 signalling axis that couples M1 polarization with monocyte recruitment. GB1107 disrupts this axis, reprograms macrophages from M1 to M2, attenuates inflammatory infiltration and ECM remodelling, and reduces apoptosis. GB1107 exerts therapeutic effects by regulating macrophage polarization and ECM remodelling, providing a novel \"immune-matrix\" dual-targeting strategy.",

Mounting evidence redefines LDs as dynamic metabolic signaling hubs orchestrating cellular stress adaptation, with multifaceted roles in organelle crosstalk, metabolic reprogramming, redox balance and immune signaling. LD function is tightly intertwined with liquid-liquid phase separation (LLPS) and epigenetic remodeling, bridging cellular metabolism to gene expression and cell fate control. LD biogenesis relies on ER lipid structures, phase-separated protein assemblies and lipid regulatory proteins. Via contacts with multiple organelles, LDs regulate lipid catabolism, ferroptosis, inflammation and chromatin accessibility, while their metabolites directly reshape epigenetic modifications and transcription. LLPS-driven biomolecular condensates further coordinate LD-linked metabolic and stress signaling. Dysregulated LD remodeling mediates metabolic flexibility, immune escape and drug resistance in obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), neurodegeneration, viral infection and cancer. This review summarizes progress in LD biogenesis and metabolism, dissects mechanistic crosstalk between LDs, LLPS and epigenetic control, and outlines LD-driven pathogenic reprogramming across human disorders. We also discuss therapeutic approaches targeting LD and LLPS pathways. Despite promising translational prospects, unresolved mechanistic and clinical hurdles persist.

While these responses can be beneficial in host defense, aberrant activation of inflammatory, lytic cell death pathways can be pathogenic. Emerging evidence suggests that cellular metabolic disruption can promote inflammatory cell death, but the mechanistic connections between these processes are not well understood, limiting our ability to identify regulatory nodes that can be therapeutically targeted. Here, we found that intracellular levels of the metabolic cofactor nicotinamide adenine dinucleotide (NAD+) were depleted in response to cell death triggers that drive pyroptosis, necroptosis, PANoptosis, and ferroptosis. However, restoring NAD+ inhibited PANoptosis but not the other forms of cell death. Mechanistically, NAD+ restoration reduced the expression of PANoptotic sensors or regulators, including the transcription factor IRF1, a critical factor for innate immune sensor priming in PANoptosis. Our findings thereby suggest that NAD+ depletion is an early cell death signaling event and that restoring NAD+ levels specifically blocks PANoptosis by suppressing priming. Hence, targeting NAD+ metabolism represents a potential therapeutic strategy for infectious and inflammatory diseases associated with dysregulated PANoptosis.",

Recent studies indicate that \u03b17 nicotinic acetylcholine (nACh) receptors modulate the inflammatory responses of immune cells. Although \u03b17 nACh receptors are expressed in microglia, their precise role in microglial activation is unclear. In this study, we determined whether \u03b17 nACh receptor stimulation could protect dopaminergic neurons from inflammation-induced injury. Nicotine and PNU-120596, an \u03b17 nACh receptor positive allosteric modulator, significantly attenuated dopaminergic neurotoxicity in primary mesencephalic cultures treated with inflammatory stimuli. However, only PNU-120596 inhibited microglial activation, and this effect was not reversed following treatment with an \u03b17 nACh receptor antagonist, suggesting a mechanism distinct from the classical \u03b17 nACh receptor-mediated signaling. PNU-120596 suppressed inducible nitric oxide synthase (iNOS) expression and signal transducer and activator of transcription 1 (STAT1) phosphorylation, but did not alter the nuclear translocation of nuclear factor-\u03baB. Moreover, in BV2 cells, which lack detectable full-length \u03b17 nACh receptor mRNA, PNU-120596 also suppressed iNOS expression and STAT1 phosphorylation. These results suggest that PNU-120596 exerts anti-inflammatory and neuroprotective effects independently of canonical pathways that are not dependent on classical \u03b17 nACh receptor-mediated signaling.",

Building on our previous work, which identified compound 20 as a promising antioxidant and neuroprotective agent, the present study investigates the molecular mechanisms underlying its protective activity against amyloid-induced ferroptosis in human neuroblastoma SH-SY5Y cells exposed to A\u03b2(25-35). Compound 20 (3-(((4-hydroxybenzyl)(methyl)amino)methyl)-1-methyl-N-(2-(piperazin-1-yl)ethyl)-1H-indole-5-carboxamide) markedly counteracted A\u03b2(25-35)-induced ferroptotic damage by restoring intracellular glutathione levels, depleting the labile iron pool, and suppressing lipid peroxidation. In parallel, the compound significantly rescued mitochondrial membrane potential and attenuated endoplasmic reticulum (ER) expansion associated with ER stress, thereby preserving cellular homeostasis under oxidative challenge. These protective effects were further corroborated by real-time PCR analysis, which revealed the modulation of key genes involved in the oxidative stress response, endoplasmic reticulum stress, and inflammatory pathways. To gain a systems-level insight into these mechanisms, untargeted 1H-NMR metabolomic profiling was performed. This analysis confirmed the activation of antioxidant pathways and disclosed a significant modulation of energy metabolism and GABA-related pathways, both of which are closely linked to redox balance and neuronal resilience. Overall, these findings demonstrate that compound 20 drives metabolic reprogramming that orchestrates its multifactorial protective effect against A\u03b2(25-35)-induced ferroptosis by coordinating antioxidant defense, iron homeostasis, and ER stress mitigation.",

We investigated whether dietary omega-3 polyunsaturated fatty acids modulate ferroptotic stress-associated pathways, defined as lipid peroxidation susceptibility and impaired antioxidant defense rather than overt ferroptotic cell death. Female Sprague-Dawley rats received either a soy oil control diet (SOD) or fish oil omega-3-enriched diet (FOD) before chronic constriction injury (CCI). Behavioral outcomes were assessed using Hargreaves and CatWalk testing, followed by dorsal root ganglion (DRG) RNA sequencing, RT-PCR, and GPX4 ELISA. Previously generated SCI metabolomics and human diabetic serum metabolomic/lipidomic datasets were re-analyzed for shared pathways. FOD attenuated CCI-induced thermal hypersensitivity and improved gait parameters. DRG transcriptomics showed reduced injury-associated transcriptional disruption, enrichment of selenoamino acid metabolism, nonsense-mediated decay, and ribosomal quality-control pathways, and reduced mitochondrial dysfunction pathway activity. Omega-3 increased Gpx1/Gpx4 expression and GPX4 protein, reduced pain-associated genes including Scn10a, Piezo2, Trpa1, and Oprm1, and aligned with selenoamino acid enrichment in SCI and human datasets. Human lipidomics showed MG/DG/PC/PE pathway remodeling. These findings support ferroptotic stress as a plausible shared downstream mechanism modulated by omega-3 supplementation across NP models.",

Nrf2 is a redox-sensitive transcription factor that coordinates antioxidant defense, iron handling, inflammatory regulation, and neurovascular unit protection through downstream effectors such as HO-1, NQO1, GPX4, and SLC7A11. Plant-derived natural compounds have been widely investigated in experimental ICH models; however, increased Nrf2 expression or nuclear translocation alone does not establish Nrf2-dependent neuroprotection. Here, we critically appraise preclinical evidence linking plant-derived natural compounds to Nrf2-centered signaling in ICH and classify the evidence into three levels: causal Nrf2-dependent evidence, Nrf2-associated evidence, and indirect or context-transferred evidence. Representative flavonoids, phenolics, terpenoids, lignans, steroidal lactones, and other bioactive compounds are evaluated with attention to ICH-model relevance, causal pathway validation, pharmacokinetic limitations, brain exposure, and therapeutic window. Current evidence indicates that only a limited subset of compounds has been validated by genetic or pharmacological Nrf2 inhibition, whereas most remain supported by pathway association rather than causality, and preclinical studies rely predominantly on young healthy rodent models with early post-ICH intervention. Notably, no compound currently reaches relatively high translational priority because perihematomal brain exposure, delayed-treatment efficacy, and long-term safety evidence remain largely unavailable. We therefore propose an evidence-based prioritization framework integrating Nrf2 causality, ICH-specific efficacy, brain bioavailability, and translational readiness. This review clarifies the mechanistic boundaries of Nrf2-targeted natural compounds and outlines priorities for rigorous translational research in ICH.",

Conventional therapies primarily manage symptoms and rarely reverse established fibrosis or restore durable bladder homeostasis. Mesenchymal stem/stromal cells (MSCs) have attracted considerable interest as therapeutic agents owing to their antifibrotic, immunomodulatory, angiogenic, and trophic paracrine activities. This review synthesises six key studies from our group and places them within the broader international literature on bladder regenerative medicine: (i) feasibility of superparamagnetic iron oxide (SPIO)-based molecular MRI tracking of transplanted human MSCs (hMSCs) in the bladder; (ii) SPIO-hMSC therapy for BOO-associated fibrosis with concurrent MRI monitoring; (iii) hepatocyte growth factor (HGF)-overexpressing engineered hMSC (B10.HGF) therapy in BOO; (iv) hMSC transplantation into the SCI-injured bladder wall monitored by MRI; (v) systematic review and meta-analysis of stem cell therapy effects on urodynamic outcomes in SCI models; and (vi) HGF-overexpressing hMSC therapy for BOO-induced underactive bladder. These six key studies are contextualised within the broader literature addressing cell sources, biomaterial-assisted delivery platforms, mechanistic pathways, emerging clinical evidence, and the evolving regulatory landscape for cell-based advanced therapy medicinal products. Key translational challenges include product standardisation, long-term durability, and mechanism-linked potency assay development.",

Ethanol Extract Attenuates LPS-Induced Neuroinflammation and Behavioral Deficits by Modulating TLR4/NF-\u03baB/NLRP3 Signaling Pathway.\nAbstract: Glycine tabacina (Labill.) Benth is commonly known as \"Yan-Dou\" and is a folk medicinal herb in China used to alleviate rheumatism. Although its anti-inflammatory and antioxidant activities have been reported, its effects on microglia-driven neuroinflammation, neuronal protection, and neuroinflammation-associated behavioral impairment have not been investigated. An LPS-stimulated microglial activation model was established using BV2 cells to evaluate the anti-neuroinflammation activity of Glycine tabacina extract (GTE) and to explore its underlying mechanisms. Neuroprotective efficacy was assessed using a BV2-HT22 conditioned interaction model to determine whether GTE mitigates microglia-mediated neuronal injury. A zebrafish model was used to examine the effects of GTE on LPS-induced neuroinflammatory phenotypes and behavioral deficits. GTE significantly inhibited LPS-induced neuroinflammation in BV2 microglia. GTE also showed a strong neuroprotective effect by suppressing HT22 cell death in the BV2-HT22 conditioned interaction model. Mechanistic assays indicated that the neuroprotective effects of GTE were associated with the inhibition of TLR4/NF-\u03baB/NLRP3 signaling cascade. In vivo studies showed that GTE mitigated LPS-stimulated neuroinflammatory phenotypes in both peripheral and central compartments and significantly improved behavioral performance in zebrafish. The results of this study demonstrate remarkable neuroprotective and anti-neuroinflammatory effects of GTE through regulation of the TLR4/NF-\u03baB/NLRP3 signaling pathway and highlight its potential as a therapeutic candidate for neuroinflammation-related CNS disorders.",

However, additional hypotheses such as ferroptosis-an iron-dependent form of regulated cell death-have gained prominence in explaining disease progression. Glutathione peroxidase 4 (GPX4), a critical antioxidant enzyme, plays a protective role by suppressing ferroptotic pathways. In this context, identifying phytochemicals capable of inhibiting AChE and exhibiting activator-like binding toward GPX4 may provide a dual therapeutic benefit. This study aimed to identify such dual-acting compounds through a structure-based virtual screening approach. Methods: A total of 3014 natural compounds were collected from three curated databases: NPACT, HIT, and HIM. Molecular docking was performed against GPX4 (7U4I) and AChE (7D9Q). Compounds demonstrating high affinity for both targets were shortlisted. Z-score normalization and statistical ranking were used to select the best two dual-target compounds. Results: Out of 3014 compounds, 68 showed dual-binding potential. Among these, NPACT00189 (docking scores: -6.720 kcal/mol for GPX4; -8.983 kcal/mol for AChE) and NPACT01210 (docking scores: -5.813 kcal/mol for GPX4; -9.640 kcal/mol for AChE) were identified as top candidates based on docking scores. Molecular dynamics (MD) simulations were conducted for both compounds for 250 ns on the AChE binding site and the allosteric site of GPX4. The results indicated that NPACT00189 maintained stable interactions throughout the simulation period at both targets, indicating its dual-targeting potential. Conclusions: NPACT00189 represents a promising dual-target candidate for further investigation in AD therapy. Its potential requires confirmation through comprehensive in vitro and in vivo studies.",

The liver, due to its pivotal role in toxin metabolism, faces an increased risk of injury from toxin accumulation. Although extensive research has been conducted on toxin-induced hepatic injury, the heterogeneity of oxidative stress mechanisms across different injury phenotypes (such as necrosis, steatosis, and fibrosis) remains poorly understood. This review systematically addresses this gap by establishing oxidative stress as the central, convergent mechanism underlying biotoxin-induced liver injury. By critically comparing representative toxins, we examine the role of oxidative stress in various biotoxin-induced hepatic injury phenotypes and their underlying molecular mechanisms. Furthermore, we discuss the specific involvement of interconnected signaling cascades-specifically the Nrf2, NF-\u03baB and MAPK pathways-in orchestrating different modes of cell death (including apoptosis, ferroptosis, and necroptosis), and summarize antagonistic strategies for biotoxin-induced hepatic injury from an oxidative stress perspective, highlighting their translational potential and providing a robust rationale for developing broad-spectrum, redox-targeted therapies.",

Accumulating evidence indicates that metabolic reprogramming not only supports tumor growth but also creates exploitable vulnerabilities linked to regulated cell death. Traditional Chinese medicine (TCM)-derived small molecules have attracted increasing attention owing to their structural diversity, multitarget properties, and broad pharmacological activities. In this review, we summarize recent advances in TCM-derived compounds targeting metabolism-associated regulated cell death in NSCLC, with a primary focus on ferroptosis and a cautious discussion of emerging cuproptosis- and disulfidptosis-related mechanisms. Ferroptosis has been extensively investigated in this context, with natural compounds shown to induce cell death through coordinated regulation of cystine transport, glutathione metabolism, GPX4 activity, iron homeostasis, and lipid peroxidation. In parallel, emerging studies suggest that certain natural products may influence copper-dependent cell death pathways and metabolic states associated with disulfide stress. These processes are closely linked to distinct metabolic features of NSCLC, including lipid dependency, copper homeostasis, and glucose utilization. Finally, we discuss major challenges for clinical translation, including poor bioavailability, off-target toxicity, insufficient biomarker stratification, and limited high-quality evidence, and highlight emerging strategies such as nanodelivery systems, structural optimization, and targeted protein degradation approaches. Overall, TCM-derived small molecules represent a promising source of metabolism-targeted therapeutics and provide a foundation for further exploration of regulated cell death in NSCLC. Current evidence is strongest for ferroptosis induction, whereas cuproptosis- and disulfidptosis-related mechanisms remain emerging areas that require further experimental validation in NSCLC models.",

Metformin, a widely prescribed antidiabetic biguanide, exerts pleiotropic effects beyond glucose lowering and has emerged as a context-dependent regulator of ferroptosis. In malignant cells, metformin may enhance ferroptotic susceptibility through activation of AMP-activated protein kinase (AMPK), suppression of mechanistic target of rapamycin (mTOR) signaling and SLC7A11, induction of ferritinophagy, mitochondrial complex I stress, and promotion of lipid peroxidation. Conversely, in normal or stressed non-malignant tissues, metformin may limit ferroptotic injury by activating nuclear factor erythroid 2-related factor 2 (NRF2), supporting glutathione peroxidase 4 (GPX4) and SLC7A11-dependent antioxidant defenses, improving mitochondrial quality control, and stabilizing iron homeostasis. This review synthesizes the molecular basis of this duality, evaluates therapeutic opportunities in oncology and cytoprotection, and outlines biomarker-driven and clinical trial strategies required for translation. Overall, metformin should not be regarded as a universal ferroptosis inducer or inhibitor, but rather as a context-dependent metabolic regulator whose effects are shaped by cell type, dose, exposure duration, transporter expression, iron status, and antioxidant capacity.",

Current therapies, including pregabalin, primarily provide symptomatic pain relief and have limited effects on preventing structural nerve damage. Therefore, the development of disease-modifying therapies remains an important unmet clinical need. This study investigated the neuroprotective effects of choline alfoscerate (CA) and its ability to attenuate mechanical hypersensitivity in a streptozotocin (STZ)-induced rat model of DPN. Methods: Diabetes was induced in rats using STZ, and administration protocols were optimized to establish sustained hyperglycemia while minimizing mortality. CA treatment was initiated immediately after STZ administration and continued throughout the study period. Mechanical sensitivity was assessed using the von Frey test. Histopathological examination of sciatic nerves was performed to evaluate structural alterations, and serum biochemical and lipid parameters were analyzed to assess systemic metabolic changes. Results: STZ-treated diabetic rats developed persistent hyperglycemia, mechanical allodynia, elevated serum triglyceride levels, and marked structural deterioration of sciatic nerve fascicles. CA treatment significantly increased paw withdrawal thresholds despite sustained hyperglycemia, indicating attenuation of mechanical hypersensitivity independent of glycemic control. Histopathological evaluation demonstrated reduced nerve fiber degeneration, attenuation of edema-like changes, and preservation of sciatic nerve architecture in CA-treated animals. In addition, CA significantly reduced serum triglyceride levels compared with diabetic controls. Conclusions: CA attenuated mechanical hypersensitivity and exerted neuroprotective effects in STZ-induced diabetic rats. These benefits occurred independently of glucose lowering and were accompanied by improvements in nerve morphology and lipid metabolism. The findings suggest that CA may represent a promising therapeutic candidate for preserving peripheral nerve integrity and attenuating neuropathic progression in diabetic peripheral neuropathy.",

(Goji Berries).\nAbstract: Medicinal and edible plants are promising resources for low-toxicity therapeutics and precision nutrition. Lycium barbarum L. (goji berry), a quintessential medicine-food homologous herb with 2000 years of ethnopharmacological use, has attracted global attention. However, existing studies are limited by fruit-centric bias, lack of correlation between processing methods, component properties and bioactivities, and incomplete antitumor mechanistic understanding. This systematic review establishes a holistic research paradigm that integrates whole-plant resource utilization, processing-property-bioactivity associations, multi-target pharmacology, and clinical translation. We delineate tissue-specific distributions of core bioactives (polysaccharides, phenolics, carotenoids, alkaloids) and their synergistic networks underlying antioxidant, anti-inflammatory, hypoglycemic, and immunomodulatory effects. Critically, we systematically summarize preclinical evidence for the antitumor potential of goji berries, identifying four proposed non-overlapping cell death pathways (apoptosis, cell cycle arrest, ferroptosis, autophagy) and proposed unique roles in reversing multi-drug resistance, alleviating chemoradiotherapy toxicity, and serving as biocompatible nanocarriers, all of which remain predominantly at the preclinical stage. We further propose a three-stage evidence-based roadmap to address key translational bottlenecks. This review bridges the gap between traditional ethnopharmacology and modern precision nutrition, providing a scientific foundation for the sustainable development of the global goji berry industry.",

Necroptosis, a regulated form of necrotic cell death, has emerged as a potential therapeutic axis in tumours resistant to apoptosis. This study aimed to develop and validate a necroptosis-related long noncoding RNA (lncRNA) prognostic signature for NSCLC and to explore its associations with tumour immune contexture and predicted drug sensitivity. RNA-seq and clinical data from TCGA and GTEx (1,128 tumours; 110 normal lung samples; 1,027 patients after filtering) were analysed. Necroptosis-related lncRNAs were identified by co-expression analysis with 67 necroptosis genes (Pearson r > 0.4, P < .001). Candidate lncRNAs associated with overall survival were selected by univariable Cox regression, refined through LASSO-penalised Cox regression with 10-fold cross-validation repeated 1,000 times, and further filtered by multivariable Cox analysis to construct the final risk model. Model performance was evaluated using time-dependent ROC curves and a clinical nomogram. QRT-PCR validated differential expression in A549 and NCI-H1299 versus BEAS-2B cell lines. Immune profiling was performed using seven deconvolution algorithms and single-sample GSEA (ssGSEA). Consensus clustering was applied to classify tumour immune phenotypes, and drug sensitivity was estimated using the pRRophetic algorithm. A 12-lncRNA signature stratified overall survival across training, test, and whole cohorts and remained independent of tumour stage in multivariable analysis. Time-dependent ROC curves yielded AUCs of 0.684, 0.652, and 0.624 at 1, 3, and 5 years, respectively. A nomogram integrating the risk score with clinicopathological variables demonstrated strong calibration. qRT-PCR confirmed differential expression of the model lncRNAs between NSCLC and normal bronchial epithelial cell lines. GSEA revealed enrichment of metabolic programmes in low-risk tumours and adhesion/cytoskeletal pathways in high-risk tumours. Immune deconvolution indicated a mixed immune milieu in high-risk tumours, with increased infiltration estimates concurrent with elevated expression of inhibitory checkpoints. Consensus clustering defined two groups: an inflamed \"hot-like\" cluster with higher immune/stromal scores and lower predicted IC50 values for multiple targeted and cytotoxic agents, and a comparatively \"cold-like\" cluster. The 12-lncRNA risk model captures biologically distinct tumour states characterised by divergent pathway activation, distinct immune microenvironmental composition, and predicted drug-sensitivity profiles. The co-occurrence of immune infiltration and inhibitory checkpoint enrichment in high-risk tumours suggests immune dysfunction rather than effective antitumour immunity, with direct implications for immunotherapy stratification. This necroptosis-related lncRNA signature provides a framework for prognostic prediction, tumour immune phenotyping, and therapeutic prioritisation in NSCLC. Prospective external validation and mechanistic functional studies are warranted to confirm clinical applicability.",

A study published in Current Cancer Drug Targets (CCDT) shows that a natural compound, Macranthoside B (MB), inhibits the activity of Adenocarcinoma of the Esophagogastric Junction (AEG) and that NRF2-mediated ferroptosis is involved in its regulation. This editorial discusses the mechanistic implications of that study, with particular attention to the NRF2/NCOA4-related ferritinophagy axis, while also emphasizing the limitations that should be addressed before clinical translation. Although the findings provide a useful preclinical rationale for exploring ferroptosis-oriented therapeutic strategies in AEG, key questions remain regarding the validation of the causal pathway, pharmacokinetics, systemic toxicity, tumor selectivity, model representativeness, and biomarker-based patient stratification. Therefore, Macranthoside B should currently be viewed as a promising experimental compound rather than a clinically established therapeutic candidate.

The objective of this study is to investigate the potential bioactive constituents of C. foetida L. for the treatment of UC, and elucidate its therapeutic mechanism. The crude polysaccharide of C. foetida L. was extracted by hot water and purified by DEAE Sepharose\u2122 Fast Flow column to obtain, and named SM05. The structure was determined by HPLC, FT-IR and SEM. The effect of polysaccharide (SM05) on the mouse UC model and its mechanism of action were investigated using a dextran sodium sulfate (DSS)-induced UC model. Changes in body weight, disease activity index, colon length, organ index, histopathological injury, cytokine expression and intestinal tight junction proteins were measured to evaluate the effect of SM05 on UC. IHC, RT-qPCR, and 16s rDNA sequencing were performed to elucidate the underlying mechanism. SM05 is mainly composed of mannose, glucose, galactose, and arabinose. SM05 exerts antioxidant effects by activating the Nrf2/Keap1 pathway, thereby inhibiting the NLRP3-induced pyroptosis pathway. This reduces abnormal intestinal cell death and the secretion of inflammatory cytokines, thus protecting the intestinal barrier and suppressing further inflammation. Additionally, SM05 modulates the gut microbiota structure in mice with ulcerative colitis by reducing pathogenic bacteria (e.g., Bacteroides and Desulfovibrio) that damage the intestinal barrier and increasing the abundance of beneficial bacteria (e.g., Akkermansia and Saccharibacteria), thereby alleviating the progression of ulcerative colitis. In the preliminary biological assessment, the polysaccharide subfraction SM05 alleviated the symptoms of UC induced by DSS. This effect may be related to the activation of the Nrf2/Keap1 pathway, the inhibition of pyroptosis, and the regulation of the intestinal microbiota.",

However, its direct involvement in cardiomyocyte injury mechanisms remains unclear. This study aimed to investigate the effects of Lp(a) on cardiomyocytes. A combination of in vitro cell culture and in vivo small animal models were used for investigations. Lp(a) induced ferroptosis through a redox-sensitive pathway via sequential p38 MAPK activation and p53-mediated transcriptional regulation. Exposure of AC16 human cardiomyocytes to Lp(a) triggered hallmark ferroptotic events, including intracellular Fe2+ accumulation, an increase in malondialdehyde (MDA) levels, and concurrent increases in p38 MAPK (p-p38) phosphorylation. Pharmacological blockade of p38 using SB203580 or siRNA-mediated p38 silencing significantly attenuated these ferroptotic markers, confirming the central role of p38 in sensitizing cardiomyocytes to ferroptosis. p38 activation drove the nuclear translocation of p53, with both pharmacological p53 inhibition (pifithrin-\u03b1) and genetic p53 knockdown effectively mitigating Lp(a)-induced lipid peroxidation and cell death. Furthermore, Lp(a) promoted an increase in intracellular reactive oxygen species (ROS) levels and initiated p38 phosphorylation, subsequently activating p53 to suppress SLC7A11 expression. These cellular findings were validated in vivo using Lp(a)-treated C57BL/6J mice, which recapitulated cardiac dysfunction, as indicated by characteristic ferroptotic markers: myocardial Fe2+/MDA elevation, glutathione/cysteine depletion, and p38-p53 axis activation. Lp(a) activates p38 by increasing intracellular ROS levels and promotes ferroptosis in cardiomyocytes via SLC7A11 inhibition, which depends on p53 activation.",

However, its associated cardiotoxicity poses a major challenge for its therapeutic use. There are numerous studies exploring the underlying cellular mechanisms behind Dox-induced cardiotoxicity. Apart from the well-established apoptosis and necrosis pathways, ferroptosis is a recently identified regulated cell death pathway being studied in the context of drug-induced cardiotoxicity. Under normal physiology, cardiomyocytes maintain a highly regulated iron homeostasis, while the polyunsaturated fatty acid-rich membrane also renders it susceptible to peroxidation, a hallmark of ferroptosis. Dox-induced cardiotoxicity disrupts the coordinated control of iron metabolism, generating reactive oxygen species, propagating lipid peroxidation, and impairing mitochondrial function. Progressive structural damage and functional loss of cardiomyocytes culminate in permanent cardiac cell death. Therefore, targeting regulatory nodes of ferroptosis may be beneficial for ameliorating Dox-induced cytotoxicity. However, it is still not clear whether the ferroptotic process merely acts as an initiator or can further act as an amplifier to upregulate the downstream signaling molecules in this cell death cascade. This review offers an overview of perspectives on the ferroptotic pathway and introduces readers to a novel driver-amplifier concept. See also the graphical abstract(Fig. 1).",

Ferroptosis, an iron-dependent, non-apoptotic form of regulated cell death characterized by the lethal accumulation of lipid peroxides, represents a pharmacologically significant vulnerability in cancers that are resistant to apoptosis and tolerant to drugs. The resistance to ferroptosis, induced by the aberrant overexpression of the epigenetic enzyme histone deacetylases (HDACs) and the sustained transcriptional activity of key antiferroptotic targets, particularly GPX4 and SLC7A11, is enforced through epigenetic mechanisms. This review examines the extant preclinical and translational data, demonstrating that HDAC inhibitors predispose cancer cells to ferroptosis through four mechanistically convergent pathways. These pathways include the transcriptional silencing of SLC7A11 and subsequent glutathione depletion, disruption of intracellular iron homeostasis via ferroportin downregulation, enhancement of mitochondrial ROS-induced lipid peroxidation, and suppression of the HDAC3-NRF2-GPX4 antiferroptotic axis. The specific roles of HDAC1, HDAC3, and HDAC10 in colorectal, lung, gastric, and hematological cancers are elucidated. Additionally, the review discusses hybrid molecules of HDAC-ferroptosis, combination strategies with GPX4 inhibitors, and immunochemotherapy. Considerations such as isoform selectivity, biomarker development, and clinical translation are addressed, highlighting HDAC inhibitor-mediated ferroptosis sensitization as a promising strategy to overcome drug resistance in cancer.

Ferroptosis, an iron-dependent regulated cell death characterized by lethal lipid peroxidation, has emerged as a promising strategy for cancer treatment. Recent studies have identified berberine, an isoquinoline alkaloid derived from Coptis chinensis and Berberis species, as an inducer of ferroptosis in various malignancies through its multitarget effects. This review systematically elucidates the molecular pathways through which berberine induces ferroptosis. These pathways include the inhibition of the System Xc-/glutathione/glutathione peroxidase 4 antioxidant axis, disruption of iron homeostasis via ferritinophagy, inhibition of mitochondrial complex I, and regulation of the upstream regulators p53, nuclear factor erythroid 2-related factor 2, and Gli1/signal transducer and activator of transcription 3 axis. Evidence specific to various cancer types, including nasopharyngeal, lung, colorectal, gastric, hepatocellular, pancreatic, prostate cancer, and osteosarcoma, was critically evaluated. Translational strategies, such as combination therapy, nanodelivery systems, and machine learning-directed structural optimization, have been examined. Additionally, the challenges of low bioavailability, resistance to ferroptosis, and complex immunological responses are discussed. Preclinical evidence suggests that berberine exhibits significant epigenetic activity, including the inhibition of DNA methyltransferases (DNMT1/DNMT3), histone modifications (H3K9me3 via SETDB1, H3K27me3 via EZH2), and modulation of oncogenic/tumor-suppressor microRNAs (e.g., miR-21, miR-155). These actions enhance its ferroptotic effects and may synergistically increase the sensitivity of cancer cells to lipid peroxidation.

Pyroptosis, an inflammatory form of programmed cell death triggered by inflammasome activation, plays a critical role in various CVDs, including hypertension, ischemia\u2011reperfusion injury (I/R injury), atherosclerosis, and heart failure (HF). Despite rapid growth of the literature, no bibliometric analysis has specifically focused on this area. Data were retrieved from the Web of Science Core Collection (1998-April 27, 2025). Bibliometric and visual analyses were performed using CiteSpace and VOSviewer to examine publication trends, country/region, funding agency, institution, author, journal, subject category, co\u2011cited reference, keyword co\u2011occurrence, and emerging hotspots. A total of 4,511 documents (2,918 original articles and 1,593 reviews) were included. China contributed 2,259 publications (50.1% of total) with 56,326 citations; the United States contributed 1,022 publications (22.7%) with 79,057 citations and the highest country\u2011level h\u2011index (147); and Italy ranked third with 290 publications (6.4%). Harvard University and its affiliated institutions led in both publication quantity and impact (h\u2011index, citations per article). Keyword co\u2011occurrence identified four clusters: pyroptosis mechanisms, NLRP3 inflammasome, signaling pathways, and CVDs. Recent bursts (2024\u20112025) highlight \"pyroptosis\" and \"ferroptosis\" as emerging frontiers. This bibliometric study identifies NLRP3 as the central research focus in inflammasome\u2011driven pyroptosis research, with the strongest citation burst. The findings reveal a shift from basic mechanistic studies toward translational research, highlighting emerging priorities such as the crosstalk between pyroptosis and ferroptosis and the need for patient stratification in future clinical trials.",

Necroptosis, a caspase-independent inflammatory form of programmed cell death, has emerged as a critical driver of the pathogenesis of cardiovascular disorders, neurodegenerative diseases, and cancer. Concurrently, our understanding of mitochondrial biology has undergone a paradigm shift: mitochondria are no longer viewed merely as bioenergetic powerhouses, but as dynamic signalling hubs that orchestrate metabolic reprogramming, cellular homeostasis, and ultimate cell fate decisions. In this regard, a growing body of evidence suggests that mitochondrial dysfunction is a central rheostat that enables necroptotic execution. This review delineates the mechanistic interplay between necroptosis and mitochondrial dysfunction and systematically analyzes the key molecular mediators and pathological pathways through which mitochondrial dysregulation drives necroptotic activation. Furthermore, this review identifies actionable therapeutic targets and translational strategies for modulating necroptosis in related diseases.",

There is substantial evidence supporting the critical role of ferroptosis in multiple neurological diseases, including stroke, Alzheimer's disease, Parkinson's disease, epilepsy, and traumatic brain injury. Histone acylation, an important epigenetic mechanism, effectively regulates ferroptosis. To date, the regulation of ferroptosis by histone acylation in neurological diseases has rarely been summarized. Therefore, this review discusses the key mechanisms by which histone acylation regulates ferroptosis, including iron metabolism, antioxidant defense, and lipid peroxidation. Additionally, we summarize the latest advances in understanding the role of histone acylation in ferroptosis and its relation to the emerging hallmarks of neurological diseases. Furthermore, we provide the prospect of targeting key regulatory factors of histone acylation, such as writers, erasers, and readers, for potential therapeutic strategies to ameliorate neurological diseases.",

Nevertheless, current therapeutic options for OA are limited to symptomatic remedies. As such, there is a high interest in novel methods for treating or preventing OA. One of the most promising medication modalities is through the clearance of cells that are cell cycle arrested but resistant to apoptosis, termed senescent cells. Additionally, these cells are also resistant to alternative programmed cell death modes, such as ferroptosis and pyroptosis. Senescent cells tend to accumulate with age due to increasing cellular and genetic damage. These cells can release inflammatory factors and signaling molecules termed senescence-associated secretory phenotype (SASP). In addition to triggering an inflammatory milieu in joints, SASP can also induce senescence in other cells through autocrine signaling. It has been shown via in vitro and in vivo tests that clearance of senescent cells through a class of drugs known as senolytics, or neutralization of SASP with senomorphics, can improve OA pathogenesis. Following these results, several clinical trials have been conducted to evaluate the efficacy of senotherapeutics against knee OA. Yet there remains a need for a comprehensive assessment of safety and optimization of senotherapeutic treatment regimens for knee OA. To this end, a better understanding of molecular mechanisms behind chondrocyte senescence and knee OA pathogenesis is necessary. Identification of novel compounds that can specifically target chondrocyte senescence pathways can assist in developing more effective therapies against OA.",

The present study aimed to develop a bioactive therapeutic platform based on an adipose-derived extracellular matrix (ECM) hydrogel incorporating cytokine-releasing PLGA microspheres to promote spinal cord repair. The hydrogel was fabricated from decellularized adipose tissue and combined with microspheres encapsulating interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and glial cell line-derived neurotrophic factor (GDNF) to achieve sustained cytokine delivery. Seventy-five male Sprague-Dawley rats were randomly allocated into five experimental groups, including control, SCI, hydrogel, microsphere, and Hydrogel\u2009+\u2009Mic groups. Tissue specimens were subsequently harvested from the lesion site for further analyses. In a rat model of SCI, treatment with the cytokine-releasing microsphere-loaded hydrogel significantly improved electrophysiological conduction and locomotor recovery compared with untreated SCI animals and groups receiving individual treatments. Molecular analyses demonstrated that the combined treatment markedly suppressed the expression of pro-inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Additionally, apoptosis-related markers showed substantial modulation, characterized by decreased Caspase-3 and Bax expression and increased Bcl-2 levels. The therapy also improved the oxidative balance by increasing antioxidant markers including GSH, SOD, and CAT while reducing the lipid peroxidation marker MDA. Furthermore, ferroptosis-associated biomarkers were significantly regulated, with elevated levels of GSH, GPX4, and SLC7A11 and reduced ACSL4 expression. Histological analyses revealed significant preservation of spinal cord architecture, reduced cavity formation, enhanced neuronal survival, and decreased glial activation in animals treated with the composite hydrogel system. Collectively, these findings demonstrate that adipose-derived ECM hydrogel loaded with cytokine-releasing microspheres provides a multifunctional therapeutic strategy that attenuates inflammation, apoptosis, oxidative stress, and ferroptosis, ultimately promoting structural and functional recovery following spinal cord injury.",

These reversible modifications intervene in the process of RNA generation, thus playing a critical role in the post-transcriptional regulation of RNA, including nuclear export, ribosome assembly, translation, and stability, thereby modulating various fundamental biological processes, such as cellular proliferation, differentiation, and cell death. Musculoskeletal disorders (MSDs), including osteoarthritis (OA), osteoporosis (OP), rheumatoid arthritis (RA), osteosarcoma (OS), and intervertebral disc degeneration (IVDD), are a major class of debilitating conditions that affect the locomotor system. Emerging evidence has demonstrated that dysregulation of m5C or ac4C modification contributes significantly to MSD pathogenesis through multiple mechanisms, including chondrocyte pyroptosis, lipid droplet dynamics, macrophage polarization, osteogenic and osteoclastic differentiation, synovial hyperplasia and invasion, and tumor-associated metabolic reprogramming. Moreover, these modifications are mechanistically linked to key pathological hallmarks, such as immune cell infiltration, ferroptosis, autophagy, and aberrant mechanical compression transduction. Pharmacological targeting of m\u2075C- and ac\u2074C-regulatory enzymes has been indicated to have therapeutic potential in animal models of MSDs. Herein, we present this review that systematically addresses the molecular basis and current knowledge on the mechanisms underlying RCMs in a variety of MSDs, along with translational strategies targeting these epitranscriptomic pathways. Finally, we present our thoughts and comments on this topic.",

Among the regulatory mechanisms implicated, microRNAs (miRNAs), which are small noncoding RNAs that regulate gene expression posttranscriptionally, have emerged as central components of several injury-related pathways. This review synthesizes current knowledge regarding the regulatory functions of miRNAs and evaluates their potential as therapeutic targets. Recent experimental and preclinical studies were analyzed to identify key miRNAs associated with injury-induced molecular responses and to assess advances in miRNA-based therapeutic strategies, including the use of miRNA mimics, inhibitors, and delivery systems. Several miRNAs, including miR-21, miR-223, miR-124, and miR-219, can regulate essential biological processes such as apoptosis, neuroinflammation, oxidative stress, glial activation, and remyelination. miR-21 and miR-223 exhibited context-dependent roles in neuroinflammation, apoptosis, and vascular repair, while miR-124 could modulate microglial activity and miR-219 facilitates oligodendrocyte differentiation and myelin restoration. Experimental therapeutic approaches employing viral vectors, nanoparticles, stem cell-based delivery, and exosome systems have resulted in enhanced tissue preservation, angiogenesis, and functional outcomes in preclinical models. miRNAs serve as critical molecular regulators and represent promising therapeutic targets. Nevertheless, clinical translation is constrained by challenges such as delivery barriers, off-target effects, and the complexity of miRNA-mediated regulatory networks. Advances in delivery technologies and research focused on precise miRNA regulation may support the development of effective neuroprotective and regenerative therapies.",

Beyond the well-defined glycolysis, dysregulated amino acid and lipid metabolism also regulate tumor growth, stress adaptation, and therapeutic resistance. Amino acids such as glutamine, arginine, tryptophan, methionine, serine, and cysteine shape biosynthesis, redox balance, one-carbon metabolism, epigenetic control, and nutrient competition in the tumor microenvironment. Lipid uptake, de novo lipogenesis, fatty acid oxidation, cholesterol remodeling, COX-PGE2 signaling, sphingolipid metabolism, and ferroptosis further influence antigen presentation, immune cell fitness, and checkpoint regulation. However, most studies still consider these metabolic axes separately, leaving the coordinated amino acid-lipid crosstalk across tumor and immune compartments insufficiently defined. This review synthesizes recent advances in amino acid metabolism, including the glutamine axis, arginine-polyamine biology, the tryptophan-kynurenine-AHR pathway, and methionine-dependent methylation programs. It then discusses lipid metabolic programs that regulate dendritic cell cross-presentation, suppressive myeloid polarization, CD8+ T cell exhaustion, PD-L1 palmitoylation, MHC-I stability, and lipid-peroxidation-linked ferroptosis. We further integrate nutrient competition, immunometabolic checkpoints, and dual metabolic targeting strategies with immune checkpoint blockade. This review provides a unified framework for identifying metabolic vulnerabilities, designing rational combination therapies and refining precision cancer immunotherapy.",

Although the natural polyphenol Procyanidin B2 (PCB2) has well-documented neuroprotective properties, its specific therapeutic efficacy in SCI, as well as its precise therapeutic targets and immunomodulatory mechanisms, remain unclear. We applied an integrated bioinformatics and in vivo approach. Target predictions were cross-referenced with SCI transcriptomic profiles from GEO datasets. Four machine learning algorithms were used to isolate core regulatory genes. Single-cell RNA sequencing mapped the primary target's distribution, and molecular docking estimated binding affinities. Mechanistic predictions were validated in a rat T10 spinal cord contusion model via Basso-Beattie-Bresnahan (BBB) scoring, histology, immunofluorescence, and Western blot. Network pharmacology initially yielded 59 shared targets, with functional enrichment pointing to PCB2's broad involvement in Toll-like receptor and p53 signaling, as well as tissue remodeling. This suggests its potential for multi-target anti-inflammatory and anti-apoptotic intervention. Machine learning algorithms then pinpointed Caspase-1 (CASP1) as the central regulatory node. Single-cell RNA sequencing showed that CASP1 expression surges specifically within macrophages and microglia following injury. Molecular docking supported a robust interaction (-7.2 kcal/mol) between PCB2 and the active pocket of CASP1. In our rat model, administering PCB2 notably hastened the return of bladder control and increased BBB locomotor scores. Histology confirmed that treated animals had smaller lesion volumes, better myelin integrity, and less inflammatory cell infiltration. At the molecular level, PCB2 significantly suppresses CASP1 expression, thereby blunting secondary damage. PCB2 demonstrates significant neuroprotective effects in SCI. Its mechanism primarily involves targeting CASP1 in myeloid cells, to lower its expression, thereby shifting the microenvironment toward repair, providing a translational basis for utilizing natural polyphenols like PCB2 in managing secondary spinal cord trauma and supporting overall central nervous system health.",
        "42519304": "ID: 42519304\nTitle: Dynamic activation of lytic cell death-related programs identifies CD14 as a candidate hub gene associated with secondary injury after spinal cord injury.\nAbstract: Secondary spinal cord injury (SCI) involves persistent inflammation, oxidative stress, and multiple forms of programmed cell death. However, the dynamic activation of lytic cell death-related programs and their key regulatory nodes during SCI progression remain unclear. Public transcriptomic datasets were analyzed using single-sample gene set enrichment analysis (ssGSEA) to assess pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities, and integrated lytic cell death-related indices were constructed. Differential expression analysis, weighted gene co-expression network analysis, functional enrichment, and multiple machine learning models were combined to identify candidate hub genes associated with lytic cell death-related signatures. Key findings were further evaluated using an external human SCI-related cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and published single-cell RNA-seq data. Pyroptosis-, necroptosis-, and ferroptosis-related transcriptional activities were all increased after SCI, with activation beginning in the acute phase and persisting over time. Enrichment analyses showed that lytic cell death-associated genes were mainly involved in inflammatory responses, immune regulation, myeloid activation, and related signaling pathways. Integrated multi-model analysis identified CD14 as the most robust candidate hub gene associated with the lytic cell death index. External validation in a human SCI-related peripheral blood cohort, RT-qPCR and immunofluorescence validation in a rat SCI model, and single-cell reanalysis further supported the upregulation of CD14 and its association with myeloid inflammatory activation and pyroptosis-, necroptosis-, and ferroptosis-related signatures. Lytic cell death-related programs are dynamically and persistently activated after SCI and are closely associated with immune-inflammatory responses during secondary injury. CD14 was identified as a candidate hub gene associated with myeloid inflammatory activation and lytic cell death-related signatures. However, the current findings are primarily associative, and further functional studies are required to determine whether CD14 directly modulates lytic cell death-related pathways and contributes to secondary injury progression after SCI.",

Ferroptosis, an iron-dependent form of regulated cell death, has emerged as a promising therapeutic avenue. However, the role of Ribonucleotide Reductase M2 (RRM2) in ferroptosis regulation and its relevance to LUAD progression remain incompletely understood. We integrated bulk transcriptomic, proteomic, WGCNA, and single-cell datasets to evaluate the clinical and biological relevance of RRM2 in LUAD. Functional validation was performed using RRM2 knockdown, ferroptosis-inducer sensitivity assays, ferroptosis-related biochemical assays, NRF2/GPX4 pathway analysis, rescue experiments, and xenograft models. RRM2 was significantly upregulated in LUAD tissues and was associated with poor overall survival. Single-cell analysis localized high RRM2 expression to a proliferative tumor cell subpopulation enriched in cell cycle- and immune-related pathways. Functionally, RRM2 knockdown suppressed LUAD cell proliferation and tumor growth and was accompanied by increased ROS, lipid ROS, Fe\u00b2\u207a, and MDA levels and decreased GSH levels. RRM2 depletion also increased ferroptosis-inducer sensitivity, with enhanced erastin and RSL3 sensitivity in A549 cells and clear RSL3 sensitization in PC9 cells. In parallel, RRM2 silencing was associated with reduced NRF2 and GPX4 expression, decreased NRF2 nuclear-to-cytosolic signal intensity, and increased ACSL4 expression. NRF2 overexpression partially restored GPX4 immunofluorescence intensity in RRM2-knockdown cells. Moreover, NRF2 overexpression or Ferr-1 treatment partially reversed the growth-suppressive effects induced by RRM2 deficiency in vitro and in vivo. RRM2 is associated with LUAD progression, ferroptosis-inducer sensitivity, and ferroptosis-related phenotypes, potentially through modulation of the NRF2/GPX4 axis. These findings support RRM2 as a candidate prognostic biomarker and a potential therapeutic target in LUAD, while the precise molecular relationship between RRM2 and the NRF2/GPX4 axis warrants further investigation.",

Existing targeted treatments face challenges such as limited applicability, modest effectiveness, and considerable costs, underscoring the demand for novel therapeutic alternatives. Growing research suggests that triggering a significant intracellular reactive oxygen species (ROS) surge can selectively induce oxidative destruction and death in tumor cells with compromised redox balance, while largely sparing normal cells. In this work, we designed lanthanum-doped zinc sulfide (ZnS:La) nanocrystals as an efficient sonocatalyst to augment sonodynamic treatment for ovarian cancer. Under ultrasound exposure, ZnS:La demonstrated improved charge separation and a notable boost in ROS generation, leading to substantial oxidative injury in cancer cells. Concurrently, the slow release of La3+ ions contributed to lysosomal membrane disruption, increasing cellular susceptibility to oxidative stress. These processes promoted the formation of PANoptosomes and initiated PANoptosis-a synergistic type of programmed cell death encompassing apoptosis, pyroptosis, and necroptosis. In evaluations using patient-derived organoids, subcutaneous grafts, and orthotopic ovarian tumor models, ultrasound-activated ZnS:La consistently inhibited tumor progression and spread. This study introduces a powerful sonocatalyst-based approach to engage multiple programmed cell death mechanisms, highlighting a potential new direction for ovarian cancer therapy.",

Ferroptosis, an iron-dependent and lipid peroxidation-driven mechanism of regulated cell death, has been associated with neurodevelopment and neurodegeneration, prompting interest in its potential role in ASD. This narrative review consolidates from molecular and clinical studies, animal models, and in vitro systems to assess ferroptosis as a candidate mechanistic pathway, biomarker source, and therapeutic target in ASD. Peripheral transcriptomic analyses reveal differentially expressed ferroptosis-related genes, ferroptosis-based molecular clusters, and immune-activated subtype in children with ASD, facilitating the development of ferroptosis-derived diagnostic and scoring models with modest yet reproducible discrimination. Clinical data associate maladaptive polyunsaturated fatty acid profiles, increased lipid peroxidation products, and adverse docosahexaenoic acid/arachidonic acid ratio with autistic social impairments, aligning with ferroptosis-prone conditions. In rodent models, genetic or pharmacological modulation of DDIT4-PI3K/Akt signaling, Nrf2/GPX4/xCT antioxidant systems, and ferritinophagy mitigates ASD-like social deficits, repetitive behaviors, anxiety-like phenotypes, and liver pathology. Induced pluripotent stem cell-derived neural progenitors from autistic children with megalencephaly exhibit heightened oxidative and iron stress, alongside active resistance to ferroptosis mediated by upregulated GPX4 and selenoprotein pathways, indicating subtype-specific ferroptosis resistance. These findings suggest a complex, context-dependent role of ferroptosis and ferroptosis resistance in ASD, interacting with immune dysregulation, redox imbalance, and peripheral organ involvement. Nevertheless, longitudinal and interventional studies integrating brain, peripheral, and cellular data are required to establish causality, define meaningful ferroptosis-related signatures, and evaluate the safety and efficacy of ferroptosis-modulating interventions.",

However, the rational design of delivery systems capable of simultaneously inducing ferroptosis, enhancing chemotherapy efficacy, and reducing systemic toxicity remains a substantial challenge. Herein, we developed a reactive oxygen species (ROS)-responsive, ionically crosslinked chitosan/hyaluronan polyelectrolyte nanogel for targeted chemo-ferroptosis combination therapy. In this system, hyaluronic acid (HA) was first esterified with 1,2-bis (2-hydroxyethylthio) ethylene (BE) and subsequently conjugated with methotrexate (MTX) through a ROS-cleavable linkage, yielding an anionic HA-BE-MTX polymeric prodrug. Protonated chitosan (CS) served as the cationic polymeric component, while sodium tripolyphosphate (TPP) further stabilized the nanogel network through ionic crosslinking. Sorafenib (SOR), a ferroptosis inducer, was physically encapsulated during the ionotropic gelation process. The resulting R-NGMS nanogels were designed to maintain colloidal stability under physiological conditions and to undergo ROS-triggered network loosening and drug release in the tumor microenvironment, where oxidative stress is elevated. This dual-delivery system enabled ROS-responsive MTX release and SOR-mediated ferroptosis induction, thereby promoting ROS accumulation, glutathione depletion, GPX4 suppression, lipid peroxidation, and apoptosis in breast cancer cells. In vivo studies demonstrated that R-NGMS efficiently accumulated in 4T1 tumors through prolonged circulation and HA-CD44-mediated tumor targeting, achieving a tumor growth inhibition rate of 75.85% with reduced systemic toxicity compared with free drug treatment. These findings demonstrate that ionically crosslinked CS/HA-based polyelectrolyte nanogels provide an effective and selective platform for ROS-responsive chemo-ferroptosis combination therapy.",

To identify genes essential for macrophage-mediated killing, we performed a genome-wide co-culture CRISPR screen and identified Androgen Receptor (AR), PRKCD, and multiple components of the NF-\u03baB pathway (IKBKB/IKBKG/CHUK) as tumor-intrinsic essential factors to allow for macrophage-mediated killing. Mechanistically, both AR and NF-\u03baB directly drive expression of PRKCD within cancer cells, functionally implicating all hits within one molecular pathway. Importantly, androgen deprivation and AR-inhibition both rendered tumor cells resistant to macrophage-mediated killing, which positions tumor-intrinsic AR signaling as a bona fide immunomodulatory pathway. Proteomic analyses showed a selective downregulation of the oxidative phosphorylation pathway in PRKCD- and IKBKG-KO cells, suggesting impaired mitochondrial function, which was confirmed by electron microscopy analyses. Finally, phosphoproteomic analyses revealed that all hits perturbing macrophage-mediated tumor cell eradication, impaired ferroptosis signaling in the tumor cells, which was confirmed transcriptionally using samples from a neoadjuvant phase II clinical trial with the AR-inhibitor enzalutamide. These data reveal immune protection from macrophages as an adverse consequence of hormonal therapy in prostate cancer patients.",

Given the growing interest in metal-based antimicrobials, copper compounds were investigated here as potential anti-Malassezia agents for SD treatment. CuSO4 showed the strongest antifungal activity against M. furfur at 1\u00a0mM and rapidly reduced fungal viability. Mechanistic analyses revealed intracellular copper accumulation, elevated Fe2+ levels, increased reactive oxygen species generation, and enhanced lipid peroxidation, collectively suggesting an oxidative damage pattern with ferroptosis-like features. Based on its potent anti-Malassezia activity, a CuSO4-loaded xanthan gum/hyaluronic acid hydrogel (HG-Cu) was further developed for integrated local treatment of seborrheic dermatitis. HG-Cu exhibited viscous-flow behavior, high structural stability, and favorable biocompatibility. In a guinea pig model of M. furfur-induced seborrheic dermatitis, HG-Cu effectively suppressed fungal proliferation in lesions through sustained copper release. Histopathological analysis showed that HG-Cu markedly ameliorated skin lesions, reduced inflammatory infiltration, and promoted matrix reconstruction and skin repair by upregulating type III collagen (COL III) at the early stage and enhancing type I collagen (COL I) deposition at the later stage. Taken together, HG-Cu offers a promising localized therapeutic approach for seborrheic dermatitis by integrating sustained antifungal activity, inflammation control, and skin barrier restoration.",

However, achieving precise and tumor-selective pyroptosis induction while preserving normal tissue integrity remains a major translational hurdle. Ultrasound has emerged as an ideal exogenous stimulus for this purpose, owing to its noninvasiveness, deep tissue penetration, and precise spatiotemporal control. Through integration with tailored nanomaterials, ultrasound energy can be specifically converted into localized biochemical signals at the tumor site, thereby triggering pyroptosis that potently stimulates antitumor immunity. This review systematically elucidates how rational nanomaterial design enables ultrasound-triggered pyroptosis (sonopyroptosis) through distinct mechanisms, including sonodynamic, sonopiezocatalytic, enzyme-mimetic, and multimodal synergistic pathways. It further delineates the ensuing immune cascade, from innate immune activation and adaptive T cell responses to the remodeling of the immunosuppressive tumor microenvironment (TME), and evaluates the synergistic potential of this approach with emerging immunotherapies such as immune checkpoint blockade (ICB) and cGAS-STING pathway activation. Finally, key challenges in clinical translation are outlined, and future perspectives are proposed to accelerate the development of nanomaterial-mediated ultrasound-triggered pyroptosis for cancer immunotherapy.",

Reciprocally, MIRI exacerbates hypertension by inducing oxidative stress, inflammatory responses, cardiomyocyte death, fibrosis-associated myocardial remodeling, and RAAS system disruption, forming a vicious feedback cycle. This study aimed to investigate the regulatory role and underlying molecular mechanism of the lactate-related signaling axis in cardiomyocyte ferroptosis during MIRI, and to identify novel potential therapeutic targets for interrupting this detrimental feedback loop. In vivo mouse MIRI models, in vitro cardiomyocyte oxygen\u2012glucose deprivation/reoxygenation (OGD/R) models, and spontaneously hypertensive rat (SHR) models were successfully established. Oxaloacetate and \u03b2-alanine were administered to inhibit lactate production and protein lactylation, respectively. Hematoxylin\u2012eosin (HE) and Masson staining were performed to evaluate myocardial histopathological damage and fibrosis. Immunohistochemistry (IHC) and Western blotting were used to detect the protein expression levels of lysine lactylation (Kla), H3K18la, alanyl-tRNA synthetase 1 (AARS1), and acyl-CoA synthetase long-chain family member 4 (ACSL4). An enzyme-linked immunosorbent assay (ELISA) was adopted to quantify the lactate content and ferroptosis-related marker levels. Transmission electron microscopy (TEM), immunofluorescence staining, and chromatin immunoprecipitation (ChIP) assays were separately utilized to observe the mitochondrial ultrastructure, assess cellular lipid peroxidation, and verify gene promoter enrichment. Lactate, Kla, and H3K18la levels were markedly elevated in the MIRI and OGD/R models, accompanied by severe myocardial injury, fibrosis, and excessive cardiomyocyte ferroptosis. Inhibition of lactate production effectively reduced lactylation levels and mitigated ferroptosis as well as myocardial structural damage. Mechanistically, H3K18la was enriched in the promoter region of ACSL4 to facilitate its transcriptional activation, and knockdown of ACSL4 markedly reversed OGD/R-triggered cardiomyocyte ferroptosis. AARS1 overexpression strengthened lactylation and ACSL4 expression to promote ferroptosis, while its mutant did not. Notably, hypertension aggravated MIRI, promotes further increases in the level of histone lactylation mediated by AARS1, and exacerbates ferroptosis. Pharmacological intervention with \u03b2-alanine blocked the lactate/AARS1/H3K18la/ACSL4 axis and attenuated MIRI-induced myocardial damage. Abnormal lactate accumulation facilitates H3K18la modification via AARS1-dependent regulation, which transcriptionally activates ACSL4 and modulates cardiomyocyte ferroptosis, ultimately contributing to the pathological progression of MIRI. Targeting the lactate/AARS1/H3K18la/ACSL4 regulatory axis is a promising and viable therapeutic strategy for MIRI intervention.",

Beyond their aggregation into plaques, A\u03b2 peptides can interact with redox-active cofactors such as copper and heme, forming complexes capable of catalyzing ROS generation. While Cu-A\u03b2 is known to oxidise catecholamines like dopamine through redox cycling, the functional implications of ternary heme-Cu-A\u03b2 assemblies remain poorly understood. In this study, we demonstrate that the heme-Cu-A\u03b2 complex catalyzes dopamine oxidation more efficiently than Cu-A\u03b2 alone, driven by a self-sustaining cooperative redox cascade involving Cu-mediated H2O2 generation and subsequent heme-mediated peroxidase-like activity in the presence of the endogenously produced H2O2. Moreover, kinetic analysis and mutant studies reveal the critical contributions of Arg5 in modulating the redox behavior of the complex. These findings establish the heme-Cu-A\u03b2 complex as a potent catalytic assembly capable of altering dopamine homeostasis under oxidative stress, offering new insights into A\u03b2-mediated neurotoxicity in Alzheimer's disease.",

Generalized Linear Models and Predictive Power Score analyses, with statistical prioritization, identified lncRNAs associated to AD neuropsychological architecture.ResultsSeveral lncRNAs share strongly associated with cognitive performance and AD severity, mapping to genes involved in key AD-related molecular processes, including synaptic and neurotransmitter regulation (e.g., EPHB1, CHRNA4, TEAD1), protein homeostasis and A\u03b2 pathology (e.g., FBXL2, FAM221A, APP), mitochondrial function and cellular stress (e.g., VDAC3, PPT2-EGFL8), neuroinflammation and immune regulation (e.g., TEAD1, EMX2OS, LY6E-DT), epigenetic and transcriptional control (e.g., PRDM2, DLEU1, FIRRE), neuronal excitability (e.g., KCNJ14), and neuroprotection and synaptic plasticity (e.g., SIL1). Novel associations included ferroptosis, DNA stability, microtubule dynamics, and dendritic orientation (e.g., BTB3, DICER1, GNG7, IBA57, NEAT1, POT1, SRD5A3).ConclusionsWe identify candidate lncRNA signatures that may serve as potential biomarkers and enhance our understanding of the molecular basis of the cognitive architecture in AD, opening new avenues for biomarker identification and targeted therapeutic strategies development. Validation in larger, diverse cohorts is essential to confirm their mechanistic contributions to AD.",

Most transformed cells arrest, yet survive when deprived of the essential amino acid methionine. We instead find that EBV transformed lymphoblastoid cell lines (LCLs), which model the EBV latency III program-driven B-cell lymphoproliferative diseases of immunosuppressed hosts, rapidly die upon methionine restriction. Methionine restriction elevated LCL lipid reactive oxygen species and triggered ferroptosis. Whereas methionine restriction hypomethylates the EBV genome and triggers viral reactivation in latency I Burkitt cells by lowering the cellular methylation potential, the LCL latency III program instead redirected methionine toward redox defense, without altering the SAM/SAH ratio. Stable-isotope tracing revealed that latency III strongly induces transsulfuration, synthesizing cysteine de novo to support glutathione pools. The EBV oncoprotein LMP2A, which mimics B-cell receptor signaling, supported newly infected human B cell cystathionine-\u03b2-synthase and cystathionine-\u03b3-lyase expression and methionine dependence, phenocopied by immunoglobulin crosslinking. In vivo , dietary methionine restriction impaired LCL xenograft outgrowth and depleted tumor cystine. Combined methioninase and cyst(e)inase administration blocked both cysteine sources, collapsed tumor glutathione levels, and triggered ferroptosis. Our results define methionine metabolism as a targetable ferroptosis vulnerability of EBV-transformed B cells.

An understanding of the specific roles of macrophage subsets in lung tumor initiation and progression could promote new therapeutic approaches for this deadly disease. Here, we show that KRAS G12D mutations in lung epithelium drive proliferation of resident, embryonically-derived alveolar macrophages, which then promote tumor cell proliferation and protection from ferroptosis, leading to tumor progression. Using genetically engineered mouse models of mutant KRAS G12D non-small cell lung cancer 12,13 , we found that alveolar macrophages accumulate by proliferation in response to tumor cell-secreted IL-34, recapitulating events observed in late embryonic lung development. Tumor alveolar macrophages in turn drive IGF-1-dependent tumor cell proliferation. Neutralization or deletion of IL-34 suppresses IGF-1 expression, reduces macrophage and tumor cell proliferation and inhibits tumor progression. High IL34 and IGF1 correlate with poor survival in KRAS G12D/V lung adenocarcinomas and in other solid tumors, indicating that bi-directional proliferative signaling between resident macrophages and tumor cells can drive human lung tumor progression. These studies identify resident macrophage-tumor cell interactions as key interception points for lung cancer therapy.",

Quiescent cancer cells residing in the bone marrow (BM) can survive the treatment and cause CML relapse. We previously found that a subset of alternative splicing (AS) changes detected in CML cells surviving months of therapy are initiated within hours of treatment onset. Here, we investigated how AS in CML cells is modulated by the human BM microenvironment. By incorporating humanized BM niche models in vivo, we uncovered stroma-induced transcriptome adaptation that influences transcriptional regulation, transmembrane transport, lipid metabolism, the tricarboxylic acid cycle, and respiratory electron transport. We identified RNA-binding protein TIAR (T-cell intracellular antigen-related protein) as a key mediator of CML survival under TKI imatinib treatment. Our data show TIAR-dependent coordination of RNA processing with the metabolic program induced by stromal interaction. Quantitative nascent proteome analysis revealed that TIAR silencing affects the synthesis of metabolic enzymes and proteins involved in imatinib-induced erythroid differentiation. Besides, TIAR knockdown increased lipid peroxidation in untreated cells and decreased reduction potential in cells upon imatinib treatment. Taken together, TIAR deficiency reduces CML survival, possibly by inducing ferroptosis. These findings identify TIAR-dependent RNA processing within the BM niche as a previously unrecognized mechanism of CML therapy resistance and a potential therapeutic vulnerability.",

With mutant KRAS being a key driver, small molecule inhibitors targeting KRAS or pan-RAS (KRASi) have demonstrated exciting preclinical and early clinical anti-tumor efficacy, and the pan-RAS(ON) inhibitor daraxonrasib (RMC-6236) recently achieved Phase 3 clinically meaningful improvements in patient survival compared to chemotherapy. But resistance to RAS/KRAS inhibitor inevitably develops, which limits and compromises the treatment outcome. In this study, we investigated the combination of stereotactic body radiation therapy (SBRT) and KRAS inhibition (MRTX1133 and daraxonrasib) in the treatment of preclinical PDAC models. We found that this combination strategy synergistically suppresses PDAC cell growth in vitro and enhances tumor control while minimizing local recurrence in orthotopically implanted KPC ( LSL-Kras G12D/+ ;Trp53 R172H/+ ;Pdx1-Cre ) murine PDAC tumors in vivo . As radiation therapy (RT) induces ferroptosis in multiple cancer types and mutant KRAS promotes various anti-ferroptotic mechanisms, we tested the role of ferroptosis in promoting tumor-control efficacy. Intriguingly, the addition of a ferroptosis inhibitor, liproxstatin-1, to the combination therapy significantly abrogated the in vivo synergism between SBRT and KRAS inhibition, suggesting that treatment-induced ferroptosis at least partially drives the synergistic efficacy of this combination strategy. Our study indicates that this SBRT-KRASi combination has the potential to overcome treatment resistance and improve outcomes in PDAC patients. These data directly support the design of a planned multi-center Phase 2 clinical trial with this combination strategy in locally advanced PDAC.",

Building on prior work demonstrating that supplementation with low-molecular weight metabolites (amino acids, vitamins, and their intermediates) can extend lifespan in Caenorhabditis elegans , we focused on pantothenate (vitamin B 5 ), which is dysregulated in sarcopenic muscle and in several neurodegenerative and metabolic disorders. Pantothenate is the obligate precursor of coenzyme A through a short, highly conserved biosynthetic pathway in which loss-of-function mutations can cause neurodegeneration with brain iron accumulation. In C. elegans , the longevity curtailing transcription factor DAF-16/FOXO has a conserved binding element in the promoter region of pnk-1 , encoding the first enzyme (PNK-1) in the coenzyme A pathway, and pnk-1 is markedly upregulated in long-lived daf-2 (insulin/-like receptor) mutants, implicating coenzyme A metabolism in longevity. Here, we demonstrate that CoA levels naturally increase during early life and decrease towards older age in C. elegans . Dietary pantothenate supplementation increases coenzyme A levels with minimal effects on lifespan but systemic effects on lipid metabolism, mitochondrial dynamics, and muscle structure under basal conditions. Under DAF-16-associated stress conditions, including heat and oxidative stress, pnk-1 expression is upregulated and pantothenate supplementation robustly extends lifespan and improves mobility. Finally, we demonstrate dysregulation of daf-16 and pnk-1 expression in amyotrophic lateral sclerosis (ALS) models, in which pantothenate supplementation confers both lifespan extension and cholinergic neuroprotection.",

Alveolar type 2 cells (AT2) are key progenitor cells responsible for lung repair and are thought to be dysfunctional in diseases such as chronic obstructive pulmonary disease (COPD). AT2 cells are highly metabolic and rely on mitochondria, but how mitochondrial mechanisms influence their maintenance and cell fate is unclear. This gap is critical as no current therapies target lung repair or mitochondrial function in COPD. Here, we report that adenine nucleotide translocase 2 (ANT2), a key ATP/ADP transporter, is reduced in AT2 cells from COPD lungs, and that ANT2 loss impairs bioenergetics (ATP). We also identify, for the first time, ferroptotic susceptibility as a consequence of ANT2 loss in AT2 cells, leading to impaired self-renewal and progenitor capacity in alveolar organoids. Together, loss of ANT2 and the associated cellular dysfunction resulted in worsened lung damage or emphysema due to cigarette smoke in mice. Therapeutic restoration of ANT2 expression resulted in renewed AT2 stem cell function and prevention of emphysema by reducing oxidative stress and ferroptosis. These findings highlight the importance of ANT2 in metabolic regulation, plasticity, and cell resiliency of AT2 cells in the lung and that ANT2 is a potential target for lung repair.",

Hysterectomy is a common gynecological surgical procedure associated with various complications. However, the relationship between hysterectomy and sarcopenia remains poorly investigated. This study aimed to explore the association between hysterectomy and sarcopenia risk. Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES, 2001-2018) was utilized for analysis. Sarcopenia was defined using the Foundation for the National Institutes of Health (FNIH) criteria based on ALM/BMI < 0.512 in women. Multivariable logistic regression and propensity score matching were applied to assess the association between hysterectomy and sarcopenia. In parallel, a senescence-accelerated mouse model (SAMP8) was used to examine the effects of hysterectomy on muscle function and related molecular pathways, including markers of protein degradation and ferroptosis. In the NHANES cohort, hysterectomy was associated with an increased risk of sarcopenia after adjustment for covariates (OR\u00a0=\u00a01.35; 95% CI: 1.00-1.82; p\u00a0=\u00a00.049). The association was stronger in women who had undergone both hysterectomy and oophorectomy (OR\u00a0=\u00a02.06; 95% CI: 1.45-2.93; p\u00a0<\u00a00.001). In SAMP8 mice, hysterectomy was associated with reduced grip strength, shorter endurance time, and decreased muscle fiber size. Molecular analyses suggested activation of the FOXO1-MuRF-1/Atrogin-1 pathway and changes consistent with ferroptosis-related signaling. Hysterectomy appears to be associated with an increased risk of sarcopenia in women, and this association is supported by findings from an experimental mouse model. These results suggest potential involvement of muscle protein degradation and ferroptosis-related pathways, although further studies are needed to clarify causality.",

Although treatment modalities have evolved considerably, tumor resistance, recurrence, and metastasis persist, urgently requiring the exploration of alternative therapies for PCa. There is ongoing research on finding and identifying the use of traditional plant medicine (TPM). Cellular homeostasis comprises a sophisticated network of metabolic processes that functions cooperatively to preserve a stable intracellular environment. Programmed cell death (PCD) plays an important role in PCa mechanism. Thus, they represent an effective strategy for targeting PCa. TPM has been proven to induce PCD through multiple pathways and target in the treatment of PCa. Recent reviews have only focused on the one of the PCD, and autophagy, apoptosis, pyroptosis, ferroptosis, and necroptosis are not simultaneously reviewed. The search strategy: articles with the title containing \"prostate cancer\", \"therapeutic\", \"traditional medicine\", \"apoptosis\", \"pyroptosis\", autophagy\", \"in vivo/in vitro\", \"active ingredients\", \"Herbal\", \"real modules\", \"dose\", \"pathway\", \"effects/mechanisms\", \"extract\", \"pure compound\", \"drug type\", \"anticancer activity\", \"Chinese herbal compounds\", \"necroptosis\" and \"ferroptosis\" had been initially selected in the past five years databases of PubMed, Web of Science, and ScienceDirect. The references were screened according to the strategy. Forty-two drugs in the TPM have been chosen in this review. The plant extract, Chinese herbal compound, and pure compound of TPM exhibit significant anticancer activity against PCa by regulating multiple kinds of PCD. More importantly, PI3K/AKT/mTOR, AMPK/mTOR pathways, AKT1/Bcl2/NF-\u03baB, GPBAR1/NF-\u03baB, Keap1/Nrf2/ARE, PINK1/Parkin signaling pathways serve as critical molecular targets mediating the anticancer activities of TPMs in PCD. Autophagy, apoptosis, and ferroptosis are research hotspots, while pyroptosis and necroptosis are less explored. Apoptosis is co-detected with autophagy, or necroptosis. Ferroptosis is co-detected with necroptosis, or pyroptosis. Notably, the interrelationships between these cell death modes are rarely investigated in depth in the treatment of TPM in PCa. TPM has been induced apoptosis, ferroptosis, necroptosis in PCa. But the effect of TPM on the autophagy and pyroptosis need further evidence to clarify the mechanism. Hence, it is imperative to focus on elucidating the role of PCD modulators to refine therapeutic strategies of TPM in PCa.",

There is an urgent need for effective, low-toxicity compounds to treat OSCC. Here, we examined whether quercetin induces ferroptosis in OSCC cells and explored the potential molecular mechanisms. The role of LGR4/NF-\u03baB/GPX4 in OSCC cells (CAL27 and SCC9) was studied through gene overexpression or RNA interference. Additionally, OSCC cell lines were treated with quercetin to examine its effects and underlying mechanisms in OSCC. Quercetin dose-dependently reduced the viability of OSCC cells, while co-treatment with the ferroptosis inhibitor liproxstatin-1 significantly counteracted quercetin-induced cell death. RNA-seq analysis showed that quercetin's inhibitory effect on OSCC cells is linked to ferroptosis induction. Quercetin concentration-dependently decreased GPX4 expression in OSCC cells by suppressing the LGR4/NF-\u03baB signaling pathway. LGR4-induced ferroptosis inhibition was counteracted by either quercetin or an NF-\u03baB inhibitor. Mechanistically, LGR4 could induce upregulation of IKK\u03b2, leading to I\u03baB\u03b1 ubiquitination and degradation, which promotes NF-\u03baB activation and GPX4 transcription, ultimately inhibiting ferroptosis in OSCC cells. Our findings indicate that ferroptosis may play a role in quercetin's anti-OSCC activity by blocking the LGR4/NF-\u03baB/GPX4 axis, which supports the potential use of quercetin as a therapeutic agent for OSCC.",

Ferroptosis, an iron-dependent form of programmed cell death driven by lipid peroxide accumulation, has emerged as a potential therapeutic strategy for HCC because it may bypass apoptosis-related resistance mechanisms. The present narrative review summarizes current evidence on ferroptosis-mediated sensitization mechanisms in combination therapy for HCC, focusing on core regulatory networks, including glutathione peroxidase 4, System Xc- and iron metabolism pathways, and their interactions with key signaling pathways, such as activating transcription factor 4/signal transducer and activator of transcription 3, p53 and Wnt/\u03b2-catenin. The current review also discusses the synergistic effects and molecular mechanisms of ferroptosis inducers combined with targeted therapy, chemotherapy and immunotherapy. Furthermore, the potential value of ferroptosis-related biomarkers for predicting treatment response and prognosis is evaluated, and unresolved mechanistic questions and barriers to clinical translation are highlighted. Finally, the present review outlines future research directions, including the development of targeted nanodelivery systems and biomarker-based clinical trials, to support more precise ferroptosis-based combination strategies for HCC.",

The disease is highly heterogeneous and is commonly detected at late stages, which compromises treatment outcomes. Ferroptosis and metabolic reprogramming are increasingly recognized as key processes in HCC development; however, their roles in disease progression and therapeutic response remain incompletely understood. This research aimed to identify genes related to ferroptosis and metabolic reprogramming (FPMRRGs) that may serve as putative biomarkers and therapeutic targets in HCC. The Cancer Genome Atlas (TCGA), including 369 HCC specimens and 50 normal controls, along with two Gene Expression Omnibus (GEO) datasets (GSE10143 and GSE76427), were analyzed using R (v4.3.3). From a curated list of 451 FPMRRGs, differentially expressed genes (DEGs) between tumor and normal tissues were identified. Univariate Cox regression analysis was then conducted to explore their prognostic relevance and to define molecular subtypes of HCC. Specimens were categorized into 2 subtypes using ConsensusClusterPlus, and overall survival differences were evaluated via survival analysis. Functional and pathway enrichment analyses were conducted to investigate the functional roles of these genes. Immune-related features were evaluated using the Mann-Whitney U test. A prognostic risk model was constructed using least absolute shrinkage and selection operator (LASSO) regression followed by multivariate Cox analysis. Model performance was assessed using receiver operating characteristic (ROC) curves and calibration plots. Immune cell infiltration was estimated by single-sample GSEA, and pathway activity differences were examined using gene set variation analysis (GSVA). HCC specimens were divided into 2 molecular subtypes, which demonstrated obvious differences in overall survival and immune-related features, including immune checkpoint gene expression and tumor immune dysfunction and exclusion (TIDE) scores. A prognostic model based on 12 key FPMRRGs demonstrated good predictive performance for 1- and 3-year overall survival, with moderate performance for 5-year survival. The prognostic value and expression patterns of these genes were further validated across independent datasets. In addition, these genes were mainly enriched in pathways linked to fatty acid metabolism and HIF-1 signaling, and were closely associated with patterns of immune cell infiltration. This study identified numerous key genes linked to ferroptosis and metabolic reprogramming in HCC and developed a robust prognostic risk model. Our results offer new insight into the molecular basis of HCC and highlight potential biomarkers for more individualized treatment approaches. Further studies, particularly those combining clinical validation with functional experiments, are required to verify these findings and examine the therapeutic potential of targeting these pathways.",

This study investigated whether arteannuin B, a sesquiterpene lactone from Artemisia annua, induces ferroptosis in CRC cells and elucidated the underlying molecular mechanism. Anti-CRC effects were assessed via MTT assays and xenograft models. Proteomics identified differentially expressed proteins. Arteannuin B-induced ferroptosis was confirmed by measuring reactive oxygen species (ROS), lipid peroxidation, Fe\u00b2\u207a content, glutathione peroxidase 4 (GPX4) expression, and mitochondrial morphology. Mevalonate pathway regulation was evaluated by western blotting, dual-luciferase assay, and quantification of squalene, coenzyme Q10 (CoQ10), and cholesterol. The role of growth differentiation factor 15 (GDF15) was validated using shRNA knockdown and overexpression DLD-1 cells in vitro and in vivo. Arteannuin B showed significant anti-colorectal cancer activity both in vitro and in vivo. The proteomic analysis demonstrated that arteannuin B affected the mevalonate pathway and ferroptosis in DLD-1 cells, and strongly upregulated the expression of GDF15. Arteannuin B increased ROS, lipid peroxidation, malondialdehyde, and iron while decreasing GPX4 expression and causing mitochondrial shrinkage. Arteannuin B inhibited mevalonate pathway enzymes, particularly 3-hydroxy-3-methylglutaryl-CoA synthase 1 (HMGCS1), reducing squalene, CoQ10, and cholesterol. The knockdown of GDF15 weakened the inhibitory effect of arteannuin B on the mevalonate pathway and GPX4, and reduced the sensitivity of CRC cells to arteannuin B both in vitro and in vivo. Arteannuin B triggers ferroptosis-like cell death in CRC cells and suppresses xenograft growth, in association with inhibition of the mevalonate pathway. GDF15 contributes to arteannuin B-mediated suppression of HMGCS1 and GPX4 and to ferroptosis sensitivity.",

The limited efficacy and significant toxicity of existing chemotherapy regimens make the development of novel natural therapeutic agents an urgent priority. Lycopene is a natural carotenoid that has been shown to inhibit multiple cancers. However, research specifically targeting PDAC remains relatively scarce. This study first employed bibliometric analysis to examine the research landscape and emerging trends in lycopene-related cancer research from 2016 to 2026. Subsequently, network pharmacology methods are applied to screen potential lycopene targets and PDAC-related targets from databases such as CTD, ChEMBL and HERB. Following the identification of overlapping targets, drug-target and protein-protein interaction (PPI) networks are constructed, as well as a disease network. The mechanisms were explored using Gene Ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Molecular docking was used to predict the potential interactions between lycopene and representative hub targets, and molecular dynamics simulations were performed for selected high-ranking docking complexes to provide supportive information on complex-level conformational stability. In vitro experiments were then conducted to evaluate the predicted anti-PDAC effects and to perform focused validation of apoptosis-related proteins and the PI3K/Akt/P53 signaling axis. Publications on lycopene research in the field of cancer have shown a sustained upward trend. The focus of this research has gradually shifted from areas such as oxidative stress and antioxidant effects towards anti-cancer mechanisms. A total of 132 overlapping targets for lycopene's anti-PDAC activity were screened, leading to the identification of 10 core targets, including BCL2, AKT1, and TP53. GO enrichment analysis revealed that these targets are involved in biological processes such as the response to oxidative stress and cellular senescence. Meanwhile, KEGG enrichment analysis identified the PI3K-Akt signaling pathway as a key pathway. Molecular docking results showed that the binding energies of lycopene with core targets such as TP53 and BCL2 were below -4.5\u202fkcal/mol. Molecular dynamics simulations provided supportive evidence for the conformational stability of representative lycopene-target complexes. In vitro experiments showed that lycopene inhibited the proliferation and migration of PDAC cells and promoted apoptosis-associated cell death, accompanied by decreased p-PI3K and p-AKT expression and increased P53 expression. This study systematically combined bibliometrics, network pharmacology, molecular docking, representative molecular dynamics simulations, and focused experimental validation to explore the potential anti-PDAC activity of lycopene. The inflammation-related hub targets identified by network analysis provide additional hypotheses for future experimental investigation. These findings provide preliminary mechanistic evidence for further preclinical investigation of lycopene in PDAC, but its translational application will require optimized formulations, pharmacokinetic validation, and in vivo efficacy studies to overcome its limited bioavailability.",

However, many cancer cells are resistant to TRAIL because of downregulation of death receptors (DRs) and overexpression of anti-apoptotic proteins. Ubiquitin-conjugating enzyme E2N (UBE2N), also known as Ubc13, plays a central role in ubiquitin-mediated cellular activities. In this study, we aimed to explore the sensitization effect of UBE2N inhibition in TRAIL-mediated apoptosis in cancer cells. NSC697923 (a potent inhibitor of UBE2N) alone and TRAIL alone did not induce apoptosis in renal carcinoma Caki cells. However, combined treatment with NSC697923 and TRAIL significantly enhanced apoptotic cell death in cancer cells, but not in normal cells. Mechanistically, NSC697923 induced upregulation of DR5 mRNA and protein levels through CHOP-mediated DR5 transcriptional activation and ubiquitin-mediated DR5 stabilization. NSC697923-mediated DR5 mRNA upregulation was regulated by upregulation of CHOP expression, a key transcriptional factor of DR5. CHOP siRNA treatment inhibited NSC697923-mediated DR5 protein expression. Moreover, NSC697923 generated ROS, and pretreatment with ROS scavengers inhibited DR5 upregulation and NSC697923 plus TRAIL-mediated cell death. These findings suggest that UBE2N inhibitor enhances TRAIL-induced apoptosis by DR5 upregulation and UBE2N inhibition may serve as a potential strategy to overcome TRAIL resistance in cancer therapy.",

Synergistic activation of multiple regulated cell death pathways has recently emerged as a novel approach to overcome therapeutic resistance. Here, we developed two mitochondria-targeted iridium(III) photosensitizers, Ir-MT1 and Ir-MT2, for synergistic photoimmunotherapy of RCC. Upon white-light irradiation, Ir-MT1/2 induced severe mitochondrial damage and dysfunction, leading to massive release of mitochondrial contents. Mitochondrial DNA leakage activated the cGAS-stimulator of interferon genes pathway and caspase-1-mediated pyroptosis cascade, whereas excessive Ca2+ efflux promoted RIPK1/RIPK3 phosphorylation and induced necroptosis. These death signals facilitated pore formation by gasdermin D and mixed lineage kinase domain-like protein in the plasma membrane, resulting in membrane rupture, release of damage-associated molecular patterns, and immunogenic cell death synergistically. In vivo, Ir-MT1/2 not only effectively suppressed primary tumor growth but also eliminated distant tumors through activation of anti-tumor immunity, exhibiting potent therapeutic efficacy and favorable biosafety. Overall, our work provides the evidence that a single iridium complex can simultaneously trigger pyroptosis-necroptosis synergy, overcoming intrinsic drug resistance and offering a promising strategy for multi-network systemic therapy of RCC.",

Quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blotting (WB) were carried out to detect gene and protein expression levels. The extent of ferroptosis was measured based on the cellular glutathione (GSH) levels and total or lipid reactive oxygen species (ROS) levels. An in-situ tumor implantation model in nude mice was employed to validate the mechanism in vivo. Transcriptome analysis was conducted to identify downstream target genes. This study found that PVT1 was highly expressed in the plasma of drug-resistant patients and drug-resistant cell lines. Silencing PVT1 reduced cellular glutathione level, increased reactive oxygen species (ROS) and lipid peroxidation (LPO), while ferroptosis inhibition in rescue experiments partially reversed the oxidative stress. In-vivo study confirmed that silencing PVT1 increased the sensitivity of BC cells to doxorubicin treatment. Transcriptomic sequencing revealed that solute carrier family 3 member 2 (SLC3A2) was the most potential target gene of PVT1, which was confirmed in PVT1-silenced cell models. Mechanistically, PVT1 increased SLC3A2 expression, thus inhibiting ferroptosis and promoting doxorubicin resistance in BC, indicating that PVT1 could be a promising therapeutic target for doxorubicin-resistant BC patients.",

In CLL cells, NOTCH1 activation may occur through mutation-independent mechanisms involving ligand interaction or cell-intrinsic, ligand-independent pathways that are not yet fully elucidated. To explore ligand-independent activation, we examined the involvement of NOTCH1 endocytic trafficking in generating the active intracellular domain (N1-ICD) in CLL cells. Using proximity ligation assay, we demonstrated that the NOTCH1 extracellular domain (N1-ECD), transmembrane subunit (N1-TM), and N1-ICD colocalize with Rab5 and Rab7, indicating NOTCH1 internalization and cleavage within endosomal compartments. Experiments with the endocytosis inhibitor Pitstop-2 demonstrated that NOTCH1 internalization is essential for N1-ICD generation. We provided evidence that N1-ICD generation occurs in Rab5 and Rab7 endosomal membranes. Treatment with chloroquine reduced N1-ICD, due to impaired endosomal acidification affecting enzymatic activity. Presenilin-1, the catalytic subunit of the \u03b3-secretase complex responsible for N1-ICD generation, was found in early endosome compartments and colocalized with Rab5, Rab7, N1-TM, and N1-ICD. CLL cells expressing N1-ICD showed higher Rab5, Rab7, and presenilin-1 levels, increased Rab5 membrane association, and presenilin-1 activity versus N1-ICD-negative cells which showed increased lysosomal targeting. Silencing Rab5 or Rab7 by siRNA, or inhibiting Rab prenylation with psoromic acid, led to reduced N1-ICD levels and increased apoptosis in CLL cells. Interestingly, NOTCH1-mutated cases showed similar NOTCH1 trafficking. These findings identify for the first time a Rab-dependent endocytic trafficking as a key regulator of NOTCH1 activation and a potential therapeutic target in CLL.",

Pathogenic tsRNAs are disease-specific or disease-related tsRNAs that are highly express in various diseases and may serve as diagnostic or potential diagnostic biomarkers. Specifically expressed tsRNAs in tumors were screened and obtained from the tumors. Although the mechanisms by which these oncogenic tsRNAs contribute to tumor development remain unclear, they have been shown to be applicable to tumor diagnosis and therapeutic prognosis. This article briefly summarizes pathogenic tsRNAs involved in various diseases and their biological functions. Oncogenic tsRNAs in tumors and their clinical applications have been elaborated upon. The molecular mechanisms of pathological tsRNAs in both general diseases and tumors need to be further investigated in future.",

Notably, this study identified that SYNCRIP expression is significantly elevated in glioblastoma (GBM) and is associated with poor prognosis and tumor progression. Mechanistically, SYNCRIP upregulates SIRT1 expression at both the transcriptional and post-transcriptional levels by stabilizing SIRT1 mRNA. Meanwhile, loss of SYNCRIP leads to reduced SIRT1 expression, accumulation of reactive oxygen species (ROS), and induction of ferroptosis. Notably, restoration of SIRT1 rescues cells from ferroptotic cell death, supporting the critical role of SIRT1 in SYNCRIP-mediated ferroptosis resistance. SYNCRIP also enhances hexokinase 2 (HK2) expression through transcriptional activation and internal ribosome entry site (IRES)-mediated translation, thereby promoting glycolytic activity in GBM. Furthermore, depletion of SYNCRIP results in mitochondrial dysfunction and impairs GBM cell migration and invasion by downregulating epithelial-mesenchymal transition (EMT)-associated factors. Collectively, these findings suggest that SYNCRIP is a key regulator of GBM progression by maintaining metabolic homeostasis and ferroptosis resistance, highlighting SYNCRIP as a potential therapeutic target in GBM.",

ZDHHC palmitoyltransferases and depalmitoylating enzymes, including acyl-protein thioesterases and palmitoyl-protein thioesterase 1, constitute a dynamic circuitry that governs the localization, stability, and signaling competence of key regulators of tumor growth, metabolic adaptation, and immune phenotype. Here, we synthesize recent structural and chemical biology advances that clarify how human ZDHHC enzymes achieve acyl-chain recognition and substrate engagement. Structural studies show that these enzymes adopt a four-transmembrane, \"tent-like\" fold, in which the helices create a membrane-embedded cavity for acyl-chain accommodation. We also discuss how ankyrin-repeat domains and accessory partners shape substrate recruitment and subcellular localization, and we highlight emerging high-throughput platforms that enable quantitative profiling of isoform- and site-selective modulators. We then discuss how ZDHHC-substrate circuits rewire canonical growth-factor signaling and epithelial-mesenchymal transition programs, metabolic and ferroptotic control nodes, innate immune sensing, and chromatin-linked regulation. These convergent mechanisms position ZDHHC-mediated S-palmitoylation as a context-dependent regulator of tumor progression, therapy response, ferroptosis sensitivity, and immune phenotype. Finally, we outline a translational framework encompassing clinical-stage PPT1 inhibitors, selective ABHD17 blockade, emerging ZDHHC modulators, substrate-competitive strategies targeting checkpoint palmitoylation, and selected comparator approaches affecting Wnt and Hedgehog ligand lipidation. Current evidence positions ZDHHC-mediated S-palmitoylation as a regulatory layer with potential biomarker and therapeutic relevance; however, not all reported ZDHHC-substrate associations carry equivalent evidentiary weight. Mechanisms supported by convergent site-directed, genetic, biochemical, functional, and in vivo evidence should be distinguished from associations inferred mainly from expression profiling, overexpression systems, single-model observations, or broad pharmacological perturbation. Clinical translation remains preliminary and is constrained by isoform selectivity, substrate redundancy, incomplete pharmacodynamic read-outs, and the absence of validated biomarker-guided patient stratification.",

However, the precise mechanism underlying LCD action against hepatocellular carcinoma (HCC) remains unclear, particularly regarding its regulation of cell death. In this study, we comprehensively explored the effects of LCD on HCC cells in vitro and investigated its role and mechanism of action in the induction of PANoptosis. Our results reveal that LCD exhibited potent anti-HCC activities by decreasing cell viability and significantly inhibiting clonogenic survival in HCC cell lines. Our results demonstrate that LCD triggered a substantial accumulation of reactive oxygen species and induced depolarization of the mitochondrial membrane, leading to profound mitochondrial dysfunction. We further confirmed that LCD activated a comprehensive PANoptosis program by synchronously upregulating the expression of apoptotic proteins (Bax, c-CASP3, and c-PARP1), pyroptotic proteins (c-CASP 1 and c-GSDMD), and the phosphorylation of necroptotic executioners (p-MLKL and p-RIPK1). Treatment with the ROS inhibitor (NAC), apoptosis inhibitor (ZVAD), or necroptosis inhibitor (Nec-1) significantly reduced the expression of PANoptosis-related proteins in LCD-treated cells. Furthermore, molecular docking simulations and cellular thermal shift assay (CETSA) assay confirmed the direct and stable binding of LCD to PANoptosis-related proteins. In summary, we show for the first time that LCD exerts favorable anti-HCC activities via the induction of PANoptosis through a ROS-dependent mechanism and potntial direct modulation of core executive proteins. This multi-target action suggests that LCD could be a novel candidate for the management of hepatocellular carcinoma.",

While natural killer (NK) cell dysfunction contributes to AA pathogenesis, the epigenetic mechanisms linking genomic instability to inflammatory hyperactivation remain poorly defined. Here, we identify the histone methyltransferase Ash1L as a critical regulator of NK cell homeostasis in AA. Ash1L expression was markedly reduced in NK cells from AA patients and correlated with disease severity and elevated proinflammatory cytokines. Ash1L knockdown reduced NK cell viability, induced apoptosis and G1 cell-cycle arrest, and enhanced secretion of IL-6 and TNF-\u03b1. Mechanistically, Ash1L deficiency resulted in reduced H3K4 and H3K36 methylation, impairing activation of the ATM-CHK2-p53 signaling pathway, resulting in persistent \u03b3H2AX foci accumulation and aberrant activation of the cGAS-STING signaling pathway. Treatment with the natural compound Andrographolide (Andro) suppressed STING signaling, enhanced DNA damage repair efficiency, and partially restored NK cell function. In an immune-mediated BMF mouse model, Andro attenuated inflammatory responses, restored Ash1L expression in NK cells, inhibited STING pathway activation, and improved hematopoiesis. Collectively, these findings suggest that Ash1L acts as an epigenetic safeguard of genomic stability and inflammatory restraint in NK cells and highlight Andro as a potential therapeutic agent for AA and related immune-mediated BMF disorders.",

This article aims to systematically review the formation mechanism of SnCs and their pathological roles in various tissue lesions, and to specifically evaluate the progress of three cutting-edge intervention strategies (Senolytics, Immuno-senolytics and Senomorphics). Senolytics selectively induces programmed apoptosis in SnCs by antagonizing senescent cell anti-apoptotic pathways. Immuno-senolytics include vaccines, engineered cell therapy and specific antibodies, which utilize the immune surveillance mechanism to achieve efficient elimination of SnCs. Senomorphics precisely reshape the SASP profile by targeting signaling axis or interfering with epigenetic modifications. Although the strategies have demonstrated remarkable potential for reversing pathology, their clinical translation still faces challenges such as the heterogeneity of SnCs, the lack of specific markers, and potential off-target toxicity. Future research should focus on multidisciplinary collaboration, aiming to optimize spatiotemporal targeted delivery systems and combination drug regimens to build a safer and more precise anti-senescence treatment system.",

Within the context of ionizing radiation, lipid pathways of particular significance include iron-dependent lipid peroxidation and ferroptosis, cholesterol and phospholipid remodeling that impacts membrane integrity and lipid rafts, lipid droplet-mediated buffering of metabolic stress, fatty acid oxidation-dependent energy supply, and sphingolipid-regulated apoptosis. This review delineates pre-existing tumor lipid programs from IR-induced adaptive responses, highlighting that their contributions to radiosensitivity or radioresistance are contingent upon tumor lineage, genetic background, microenvironmental conditions, and treatment context. The coupling of cancer cells with their microenvironment through lipid interactions, encompassing intercellular lipid transfer, nutrient competition, paracrine lipid mediators, and exosome-mediated signaling, is identified as a central component of radioresistance. In conclusion, therapeutic opportunities are evaluated based on their translational maturity, encompassing a spectrum from mechanistic concepts and preclinical radiosensitization strategies to approaches with emerging clinical significance. This synthesis, focused on radiotherapy, seeks to elucidate how lipid vulnerabilities can be strategically and judiciously exploited to enhance radiation outcomes.",

In this study, we investigated the anticancer efficacy and underlying mechanisms of Stellettin B, an isomalabaricane triterpene isolated from the marine sponge Jaspis stellifera, in OSCC cells. Our results demonstrate that Stellettin B significantly inhibited the proliferation of HSC-3 and OC-2 cells while sparing normal oral keratinocytes. Mechanistically, Stellettin B triggers a predominantly caspase-independent apoptotic program, evidenced by the pronounced mitochondrial-to-nuclear translocation of apoptosis-inducing factor (AIF) and endonuclease G (EndoG) following DNA damage, whereas classical caspase activation functions as a dispensable, secondary event. Furthermore, Stellettin B suppressed migration and invasion by reversing epithelial-mesenchymal transition (EMT), characterized by E-cadherin upregulation and downregulation of Vimentin, Snail, Slug, and \u03b2-catenin. Transcriptomic profiling further revealed significant suppression of mTORC1 signaling and EDIL3 expression. In conclusion, these findings demonstrate that Stellettin B exerts multimodal antitumor activity in OSCC and highlight its therapeutic potential as a marine-derived anticancer agent.",
        "42524633": "ID: 42524633\nTitle: Molecular and developmental consequences of heat stress on the bovine oocyte and embryo competence.\nAbstract: Seasonal heat stress (HS) is a pervasive environmental challenge with profound consequences for female reproductive physiology, affecting ovarian function, oocyte maturation, and early embryonic development. At the ovarian level, HS disrupts follicular growth, impairs steroidogenesis, and compromises granulosa cell function, thereby creating a suboptimal microenvironment that reduces oocyte competence. In oocytes, HS induces oxidative stress, mitochondrial dysfunction, endoplasmic reticulum (ER) stress, spindle abnormalities, chromosomal missegregation, and persistent epigenetic alterations. These disruptions extend into early embryonic development, where redox imbalance, apoptosis, ER stress, and altered lineage allocation reduce cleavage and blastocyst formation, compromise trophectoderm and inner cell mass integrity, and impair implantation potential. Maternal heat exposure further exacerbates embryonic vulnerability by altering the oviductal and uterine environment, reducing embryotrophic factors and antioxidant defenses, and ultimately influencing offspring phenotype and fertility, potentially across generations. Accordingly, this review aims to synthesize current knowledge on the physiological and molecular impacts of heat stress on ovarian function, oocyte maturation, and early embryonic development. To this end, we consider studies conducted under both in vivo and in vitro conditions, highlighting shared and distinct mechanisms of thermal stress at the organ and cellular levels to identify potential targets for intervention.",

There is growing evidence of an association between circadian rhythm disturbance and PCOS, but the underlying molecular mechanisms This study aimed to explore the molecular mechanism of PCOS induced by circadian rhythm disturbance and evaluate the therapeutic potential of melatonin. A rat model of circadian rhythm disturbance was established via 24-h continuous light exposure. Rats were randomly divided into the Control group (normal circadian rhythm), Model group (continuous light exposure), and Model\u2005+\u2005Melatonin treatment group (continuous light exposure\u2005+\u2005melatonin). Reproductive endocrine indicators, ovarian histomorphology, and ovarian granulosa cell (GC) function were assessed. Additionally, circadian rhythms of serum hormones, autophagy-related markers (LC3), and hypothalamic clock genes were detected at six zeitgeber time (ZT) points. Autophagy and apoptosis levels in GCs, as well as the activation of MAPK and PI3K/Akt/mTOR pathways, were also detected. Continuous light exposure induced PCOS-like phenotypes in rats, characterized by disrupted estrous cycles, cystic ovarian changes, and loss of circadian rhythms in serum hormones, autophagy marker LC3, and hypothalamic clock genes. Moreover, continuous light exposure reduced GC viability, increased GC autophagy and apoptosis, activated the MAPK pathway, and inhibited the PI3K/Akt/mTOR pathway in GCs. Melatonin treatment significantly ameliorated these PCOS-like phenotypes. Our study showed circadian rhythm disturbance induced PCOS via MAPKs and PI3K/Akt/mTOR signaling pathways and increased autophagy level in rat ovarian GCs. Melatonin had a therapeutic effect on PCOS by reversing these signaling pathway abnormalities and reducing autophagy and apoptosis levels in GCs.",

Consequently, redox-modulating therapies are increasingly explored as potential therapeutic strategies. This review evaluates the mechanistic basis, experimental evidence, and clinical applicability of hydrogen-rich water (HRW) in oxidative stress-related diseases. A structured literature search identified mechanistic, preclinical, and clinical studies investigating HRW or molecular hydrogen (H2) on oxidative stress, inflammation, mitochondrial regulation, and disease-related outcomes. Due to substantial methodological heterogeneity, findings were synthesized qualitatively. HRW has been proposed to selectively neutralize highly reactive species such as hydroxyl radicals (\u2022OH) and peroxynitrite (ONOO-) while preserving physiological reactive oxygen species signalling. Mechanistic studies demonstrate activation of nuclear factor erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE) pathways, suppression of nuclear factor kappa B (NF-\u03baB) and mitogen-activated protein kinase (MAPK) inflammatory cascades, modulation of JAK/STAT signalling, preservation of mitochondrial bioenergetics, and enhancement of autophagic regulation. Preclinical and clinical studies report improvements in glycaemic control, endothelial function, cardiometabolic health, neuroprotection, exercise performance, and treatment-related fatigue. Despite an excellent safety profile, standardization of HRW preparation and large multicentre randomized controlled trials (RCTs) remain necessary to establish clinical efficacy and translational potential.",

However, the molecular mechanism underlying its anticancer effects, especially its direct target proteins, remain to be fully elucidated. Here, we found that Oridonin promoted intracellular reactive oxygen species (ROS) accumulation, which in turn induced endoplasmic reticulum (ER) stress-mediated apoptosis. Moreover, ER stress was instrumental in inducing autophagy after Oridonin treatment, while blockade of autophagy further exacerbated Oridonin-induced cytotoxicity. Notably, using activity-based protein profiling (ABPP), we identified the anti-oxidant enzyme Peroxiredoxin 1 (PRDX1) as a key direct covalent target of Oridonin. By binding to Cysteine 173 of PRDX1, Oridonin increased intracellular ROS levels. Furthermore, PRDX1 over-expression mitigated, whereas PRDX1 knockdown potentiated, Oridonin-induced ROS accumulation, autophagy, and subsequently apoptosis. Overall, our results indicate that PRDX1 is a direct covalent binding target mediating Oridonin-induced apoptosis. These findings not only provide fresh insights into the core mechanism of Oridonin-induced cytotoxicity, but also highlight PRDX1 as a potential therapeutic target for renal cancer drug development.",

This study reports the synthesis and characterization of a latex-hybrid nano-carrier derived from Nerium oleander (LHNC), engineered for cisplatin (CDDP) delivery in breast cancer models. Physicochemical analyses confirmed stable, porous nanostructures with uniform particle size (\u223c120-150\u2009nm), moderate surface charge (+21\u2009mV), and high drug loading efficiency (\u223c85%). The system exhibited pH-responsive sustained release under acidic conditions, mimicking the tumor microenvironment. Biological evaluations demonstrated that LHNC/CDDP significantly enhanced cytotoxicity compared to free CDDP, reducing MCF-7 cell viability to \u223c38% at 24\u2009hrs. Mechanistic studies revealed elevated ROS generation, mitochondrial membrane depolarization, nuclear condensation, and caspase-mediated apoptosis. Flow cytometry confirmed pronounced G2/M arrest and increased apoptotic fractions, validating the pro-apoptotic and anti-proliferative effects of the nano-carrier. Comparative analyses across luminal (MCF-7), triple-negative (MDA-MB-231), and non-tumorigenic (MCF-10A) models highlighted selective cytotoxicity toward malignant cells while sparing normal epithelial cells. Collectively, these findings position LHNC/CDDP as a promising bioinspired nanocarrier platform that integrates natural polymer advantages with chemotherapeutic precision. While the in vitro data provide compelling proof-of-concept, translational application requires rigorous toxicological evaluation, dose optimization, and in vivo validation, particularly given the bioactive cardiac glycosides in N. oleander.",

Here, we engineered a stage-adaptive Janus microneedle patch (MN-FeSAC-PPE) to enable a staged therapeutic process from early antibacterial intervention to subsequent redox-immune microenvironment remodeling and regenerative tissue repair. This stage-adaptive design integrates Fe single-atom nanozymes (Fe-SACs) into the microneedle base to rapidly kill bacteria using near-infrared light, which activates reactive oxygen species (ROS) production, enabling rapid antibacterial activity against wound pathogens. Meanwhile, propolis extract-loaded (PPE) tips deliver antioxidant bioactive compounds into the wound bed to mitigate oxidative stress, modulate the redox-immune microenvironment, and support the inflammatory-to-regenerative transition. In vitro, MN-FeSAC-PPE enhanced antioxidant defense, suppressed pro-inflammatory factors, and protected fibroblasts from oxidative stress-induced mitochondrial dysfunction. Transcriptomic analysis further supported reduced inflammatory signaling and enhanced metabolism-related programs. In S. aureus-infected diabetic wounds, NIR-activated MN-FeSAC-PPE accelerated wound closure, promoted angiogenesis and collagen remodeling, and alleviated inflammation.

Upon infection, the virus triggers a robust inflammatory response characterized by the release of pro-inflammatory cytokines, which play a central role in lung injury. It also alters the host antioxidant response, causing oxidative stress that supports viral replication and cytokine overproduction. This study investigated key pathogenic effectors in Calu-3 and A549-ACE2/TMPRSS2 cells infected with SARS-CoV-2 variants, focusing on replication kinetics, cellular redox state, and inflammatory cytokine profile. A dramatic redox alteration in terms of glutathione (GSH) and Cysteine (Cys) was observed at 48 h p.i., along with a strong pro-inflammatory cytokine response , likely via activation of the JNK/AP-1 signaling pathway. To counteract these effects, two thiol molecules were tested: I-152, a monothiol conjugate of N-Acetyl-Cysteine (NAC) and \u03b2-mercaptoethylamine (MEA) and its dithiol derivative, I-152SdAc. Thiols restored GSH balance by enhancing the expression of Nrf2-mediated genes, such as glutamate-Cys ligase modifier subunit (GCLM), and counteracted AP-1-mediated pathway, resulting in a significant reduction of inflammation and viral replication. Antiviral and anti-inflammatory activities of thiols were confirmed in NHBE cells. These findings highlight that redox imbalance is a key pathogenetic event in SARS-CoV-2 infection. Notably, besides Nrf2 and AP-1, other redox-sensitive factors, such as the CHAC glutathione-specific gamma-glutamyl-cyclotransferase 1 (CHAC1), seem to contribute to the pathogenesis and may represent a new potential therapeutic target of redox active compounds. Therefore, the thiol-derived molecules act as broadly effective compounds by limiting virus replication and inflammation.",

Human umbilical cord mesenchymal stem cells (hUC-MSCs) hold promise due to their neuroprotective and immunomodulatory effects, but their underlying mechanisms remain unclear. This study established a PND model in aged mice using tibial fracture intramedullary fixation surgery, followed by intravenous hUC-MSCs administration. Subsequently, behavioral tests, pathological examination, proteomic analysis, and other experiments were performed to verify the therapeutic effect and underlying mechanism of hUC-MSCs on PND in mice. hUC-MSCs significantly improved cognitive function in PND mice, reduced hippocampal neuronal apoptosis and neuroinflammation, and restored dendritic spine density. Mechanistically, hUC-MSCs secreted \u03b2-NGF to activate the TrkA signaling pathway, upregulate STMN2 and NMNAT2 expression, and inhibit the SARM1/NF-\u03baB pathway, thereby alleviating neuroinflammation and dendritic degeneration. Overexpression of SARM1 in the hippocampal CA1 region and \u03b2-NGF knockdown in hUC-MSCs both reversed the therapeutic effects of hUC-MSCs, confirming their critical roles. hUC-MSCs ameliorate PND pathology through the \u03b2-NGF-mediated STMN2/NMNAT2-SARM1-NF-\u03baB pathway, offering a novel cell-based therapeutic strategy for PND.

This study developed an innovative and efficient screening platform combining hydrogen peroxide test strip-based colorimetric sensing with affinity chromatography for rapid identification of acetylcholinesterase (AChE) inhibitors from complex herbal medicines. Applying this strategy, from Lycium barbarum leaves, we identified three potent inhibitors: chlorogenic acid, N-acetyl-N'-caffeoylputrescine (NANCP), and N-caffeoylputrescine (NCP), with IC50 ranging from 55.7 to 143.2\u00a0\u00b5m. Molecular analyses confirmed their stable binding to AChE. In a D-galactose and AlCl3-induced Alzheimer's disease (AD) mouse model, NCP treatment significantly rescued cognitive deficits in AD mice, with the spontaneous alternation rate in the Y-maze test improved by up to 50%. It markedly reduced cerebral A\u03b2 levels (by 54%) and pro-inflammatory cytokines, including TNF-\u03b1, IL-1\u03b2, and IL-6, alleviated oxidative stress, and attenuated hippocampal neuronal damage.

Forty-eight male Wistar albino rats were randomly assigned to six groups: control, sham, torsion/detorsion (T/D) 4 h, T/D + SA 4 h, T/D 24 h, and T/D + SA 24 h. Testicular torsion was induced by 720\u00b0 rotation of the left testis for 2 h, followed by detorsion and 4 or 24 h reperfusion. SA (10 mg/kg) was administered intraperitoneally 30 min before detorsion. Oxidative stress markers, histopathological alterations, and immunohistochemical expressions of apoptotic protease activating factor-1 (APAF-1) and inducible nitric oxide synthase were evaluated. T/D significantly decreased total antioxidant status and glutathione levels while increasing myeloperoxidase activity and APAF-1/inducible nitric oxide synthase (iNOS) expressions compared with controls (p < 0.001). SA treatment restored antioxidant capacity and attenuated inflammatory and apoptotic responses (p < 0.05). Histopathological analyses demonstrated lower Cosentino scores and higher Johnsen scores in SA-treated groups than in untreated T/D groups (p < 0.05).

In GSE97123, 292 differentially expressed miRNAs (p\u2009<\u20090.05) were identified in circulating exosomes from T1D patients compared with controls, with upregulation of pro-inflammatory mediators including miR-155-5p and miR-146a-5p. In GSE92439, T lymphocyte-derived exosomes altered 8,189 genes in pancreatic islets, with changes in insulin secretion, apoptosis, and immune recognition pathways. In GSE316823, cytokine-stimulated ductal cell EVs induced 599 differentially expressed genes in \u03b2-cells, with notable upregulation of HLA class I molecules (HLA-A, HLA-B, HLA-C) and inflammatory chemokines (CXCL9, CXCL10, CXCL11, IDO1, GBP4). In GSE160391, cytokine stress caused distinct miRNA packaging into EVs versus islet fractions, with miR-155-5p and miR-146a-5p as the only two miRNAs consistently upregulated in both compartments across sexes. Cross-dataset integration showed convergent dysregulation of antigen presentation, insulin signaling, and apoptotic pathways. Immune cell-derived EVs appear to transfer pro-inflammatory and metabolic-disruptive cargo to \u03b2-cells, supporting a pathogenic axis in T1D that has received limited attention. These findings suggest that EV-mediated communication could be a therapeutic target and that circulating EV miRNAs may serve as biomarkers for T1D progression.",

Tripartite motif-containing 24 (TRIM24) is an oncogenic TRIM family protein with E3 ubiquitin ligase and transcriptional co-regulator functions. This study aimed to elucidate the critical role of TRIM24 in modulating VSMC functions and neointimal hyperplasia. Our in-silico network pharmacology analysis revealed that the TRIM24 inhibitor, IACS-9571, engages multiple hub genes and key pathways involved in VSMC proliferation, apoptosis, autophagy, migration, and extracellular matrix remodeling. Using Western blot and immunofluorescence analysis, we found that platelet-derived growth factor-BB (PDGF-BB) stimulation of murine primary aortic VSMCs, significantly upregulated TRIM24 expression. SiRNA-mediated knockdown of TRIM24 attenuated PDGF-BB-induced VSMC proliferation. Pharmacological inhibition of TRIM24 using IACS-9571 markedly suppressed PDGF-BB-induced VSMC proliferation, migration, and phenotypic switching. Furthermore, TRIM24 blockade enhanced autophagy in VSMCs, as evidenced by elevated LC3 and Beclin-1 protein levels, accumulation of LC3 puncta and transcriptional upregulation of autophagy-related genes, namely ATG7 and ATG4B. Also, TRIM24 inhibition reduced AKT and mTOR activation compared to PDGF-BB-stimulated VSMCs. Concurrently, TRIM24 inhibition elevated mitochondrial ROS levels, upregulated BAX expression, a pro-apoptotic gene, and significantly enhanced apoptosis, as confirmed by TUNEL and Annexin V/PI assays. In vivo, Immunofluorescence analysis demonstrated elevated TRIM24 expression within the neointimal regions. Perivascular application of the TRIM24 inhibitor prevented wire injury-induced neointimal hyperplasia. These findings identify TRIM24 as a key regulator of VSMC proliferation, migration, and phenotypic switching. Targeting TRIM24 promotes autophagy and induces apoptosis, offering a promising strategy to limit neointimal hyperplasia and pathological vascular remodeling.",

The transcription factor SOX9 has been linked to AD progression, but its mechanism remains unclear. SOX9 expression was measured in peripheral blood mononuclear cells from 24 patients with AD and 24 age-matched healthy controls and correlated with Montreal Cognitive Assessment scores. An A\u03b21-42-stimulated BV-2 cell model was used to investigate the effects of SOX9 and apoptosis signal-regulating kinase 1 (ASK1) on microglial polarization. Neuronal injury was evaluated in a BV-2/SH-SY5Y co-culture system. The transcriptional regulation of ASK1 by SOX9 was examined using dual-luciferase reporter and chromatin immunoprecipitation assays. ASK1 overexpression and the ASK1 inhibitor GS-4997 were used for mechanistic validation. SOX9 expression was increased in peripheral blood mononuclear cells from patients with AD and was negatively correlated with cognitive function. SOX9 was also upregulated in A\u03b21-42-stimulated BV-2 cells. SOX9 overexpression enhanced M1-associated inflammatory markers and reduced M2-associated markers, whereas SOX9 knockdown produced the opposite effects. In the co-culture system, SOX9 knockdown increased SH-SY5Y cell viability, reduced LDH release and apoptosis, increased Bcl-2 expression, and decreased Bax and cleaved caspase-3 expression. SOX9 bound to the ASK1 promoter and promoted ASK1 transcription. SOX9 silencing suppressed ASK1, JNK, and p38 phosphorylation, while ASK1 overexpression reversed the effects of SOX9 knockdown on microglial polarization and neuronal injury. Consistently, GS-4997 blocked the pro-inflammatory and neurotoxic effects induced by SOX9 overexpression. SOX9 exacerbates AD neuroinflammation by promoting microglial M1 polarization via the ASK1/JNK signaling axis.",

Unlike earlier reviews, based mainly on data collected before the year 2020, when environmental exposure levels were substantially lower, this work synthesizes research conducted over the last five years (2020-2025), a period that includes the SARS-CoV-2 pandemic. The pandemic was associated with a sharp global increase in the consumption of NSAIDs, resulting in their markedly elevated environmental loads. Consequently, the studies assessed in this review reflect plant and algal responses under significantly higher contamination pressures than those reported in pre-pandemic decades, offering a new perspective on their phytotoxic potential. A systematic literature search retrieved over 5,000 records, from which the most relevant experimental studies were selected for detailed evaluation. The compiled evidence demonstrates that NSAIDs adversely affect photosynthesis, induce ultrastructural damage to chloroplasts, and compromise mitochondrial respiration, including alterations in membrane potential and ATP production. Exposure to NSAIDs triggers oxidative stress responses, characterized by reactive oxygen species overproduction, lipid peroxidation, and variable changes in antioxidant enzyme activity. Beyond primary metabolism, numerous reports document disruptions in growth patterns, root system architecture, mineral balance, and secondary metabolite biosynthesis. By integrating the most up-to-date findings from a period of exceptionally intense pharmaceutical pollution, this review provides a novel and more realistic assessment of the ecological risks posed by NSAIDs. It underscores the urgency of developing stricter environmental quality standards and highlights key directions for future research under contemporary contamination scenarios.",

Currently, safe and effective strategies for preventing doxorubicin-induced cardiotoxicity (DIC) remain limited. Therefore, this study aimed to investigate the potential cardioprotective effects and possible underlying mechanisms of L-arginine (L-Arg) against DIC. To investigate the cardioprotective effects and underlying mechanisms of L-Arg, three complementary experimental models were used: male Sprague-Dawley rats (n\u2009=\u20096 per group), male AMPK\u03b12 knockout (AMPK\u03b12 KO) mice (n\u2009=\u20096 per group), and H9c2 cardiomyocytes. A DIC model was induced in rats by intraperitoneal injection of DOX (2.5\u00a0mg/kg/week) for 6 weeks. Serum nitric oxide (NO) and lactate dehydrogenase (LDH) levels were measured to assess oxidative stress and myocardial injury. Cardiac morphology, inflammation, and fibrosis were evaluated by histological staining and protein expression analyses, whereas miR-29b-3p expression was determined by RT-qPCR. AMPK\u03b12-deficient models and miR-29b-3p gain- and loss-of-function models were used to investigate the underlying mechanisms. Compared with the DOX group, L-Arg significantly improved cardiac function and morphology, reduced oxidative stress, myocardial injury, inflammation, and fibrosis, and increased miR-29b-3p expression (all P\u2009<\u20090.05). Moreover, miR-29b-3p overexpression enhanced, whereas miR-29b-3p inhibition attenuated, the cardioprotective effects of L-Arg (all P\u2009<\u20090.05). These protective effects were also markedly attenuated by AMPK\u03b12 deficiency (P\u2009<\u20090.05). L-Arg alleviates DIC by improving cardiac function, reducing oxidative stress, inflammation, and fibrosis, and increasing miR-29b-3p expression. These cardioprotective effects are associated with AMPK\u03b12 activation and enhanced miR-29b-3p expression.",

Long non-coding RNAs have shown potential as biomarkers in tumors, but the function of DNM3OS in CC is unclear. This study investigates the prognostic value of DNM3OS in CC and its functional effects in tumor cells, aiming to identify a promising biomarker for this cancer. DNM3OS expression was measured in tumor and normal tissues from 152 patients with CC using RT-qPCR, and its association with progression-free survival and clinical parameters was analyzed. The role of DNM3OS on proliferation, invasion, apoptosis, and epithelial-mesenchymal transition (EMT) in CC cells was examined following overexpression or knockdown. The binding between miR-454-3p and DNM3OS was verified, and functional rescue experiments were conducted by upregulating miR-454-3p. DNM3OS was significantly downregulated in CC tissues, and its low expression was associated with larger tumor size, lymph node metastasis, and advanced FIGO stage. DNM3OS acted as an independent factor for prognosis, with its low expression correlating with poor progression-free survival in CC patients. DNM3OS directly bound to miR-454-3p. Overexpression of DNM3OS suppressed the proliferation, EMT, and invasion of CC cells, while promoting apoptosis. These antitumor effects were partially counteracted by miR-454-3p overexpression. Downregulation of DNM3OS predicts poor prognosis in CC, and DNM3OS suppresses the biological behavior of tumor cells by sponging miR-454-3p. DNM3OS may serve as a prognostic biomarker for CC.",

Cholesterol supports neuronal membrane structure, synapse formation, synaptic vesicle activity, receptor signaling, and myelin integrity. Because the blood-brain barrier limits the entry of peripheral lipoproteins, the brain relies mainly on local cholesterol synthesis, transport, recycling, and turnover. This review examines the mechanisms that regulate astrocyte-to-neuron cholesterol transfer and explains how defects in SREBP-dependent synthesis, ApoE lipidation, ABC transporter-mediated export, neuronal uptake, intracellular trafficking, and cholesterol turnover contribute to synaptic dysfunction and neurodegeneration. In the adult brain, astrocytes are an important source of cholesterol for neurons. Astrocytic cholesterol synthesis is regulated by sterol regulatory element-binding proteins, which control the expression of key cholesterol-biosynthetic genes. Astrocytes release cholesterol in ApoE-containing lipoprotein particles through ATP-binding cassette transporters. Neurons acquire astrocyte-derived cholesterol through LDLR/LRP1, redistribute it via NPC1/NPC2, and eliminate excess cholesterol as 24 S-hydroxycholesterol through CYP46A1. Disruption of this pathway impairs membrane organization, lipid raft signaling, synaptic function, and neuronal survival. These disturbances are associated with Alzheimer's disease, Huntington's disease, and multiple sclerosis.",

Celastrol has recognized anti-inflammatory activity, but its mechanism in RA remains incompletely defined. This study investigated whether the anti-arthritic effect of celastrol is associated, at least in part, with a PTGS2-associated ferroptosis-resistance pathway in FLS. Potential targets of celastrol in RA were identified through integrated bioinformatic analyses. Collagen-induced arthritis (CIA) rats and primary FLS were used to evaluate the effects of celastrol in vivo and in vitro. Joint pathology, inflammatory mediator expression, oxidative stress, iron accumulation, lipid peroxidation, and ferroptosis-related proteins were assessed. Loss- and gain-of-function experiments were performed to examine the functional role of PTGS2. Bioinformatic screening identified PTGS2 as a candidate functional mediator linking celastrol to RA. In CIA rats, celastrol reduced paw swelling, arthritis severity, synovial hyperplasia, inflammatory cell infiltration, and cartilage and bone destruction. In FLS, celastrol suppressed cell proliferation and migration and decreased the expression of pro-inflammatory cytokines. Mechanistically, the combined changes in intracellular iron, lipid peroxidation, mitochondrial function, and ferroptosis-related proteins supported attenuation of a ferroptosis-resistant phenotype after celastrol treatment. PTGS2 expression was markedly elevated in RA models and was downregulated by celastrol. PTGS2 overexpression attenuated the anti-inflammatory effects of celastrol and reversed several ferroptosis-associated changes, supporting a functional role for PTGS2 in this process. Celastrol alleviates synovial inflammation and experimental arthritis, at least in part, in association with PTGS2 modulation and attenuation of a ferroptosis-resistant phenotype in FLS. To our knowledge, these findings provide experimental evidence linking celastrol, PTGS2-associated regulation, and ferroptosis resistance in RA models.",

The Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway mediates cytokine-driven signaling, and its persistent activation contributes to tumor growth, invasion, immune escape, and therapeutic resistance. Suppressor of cytokine signaling 3 (SOCS3) is a key negative regulator of cytokine and growth factor signaling, especially the IL-6/JAK/STAT3 axis. This review summarizes the structure and physiological functions of SOCS3 and discusses its dysregulation in CRC initiation, progression, metastasis, prognosis, and treatment response. Current evidence indicates that SOCS3 is frequently downregulated in CRC through promoter methylation and post-transcriptional regulation by oncogenic microRNAs, leading to sustained STAT3 activation, increased proliferation, reduced apoptosis, and enhanced invasiveness. SOCS3 also interacts with MEK/ERK and PI3K/AKT signaling and influences the tumor microenvironment by regulating T-cell balance, PD-L1 expression, and macrophage activity. Clinically, reduced SOCS3 expression has been associated with lymph node metastasis, advanced TNM stage, and poorer prognosis, whereas higher SOCS3 levels may correlate with improved outcomes and chemosensitivity. Emerging therapeutic strategies include epigenetic modulation, JAK/STAT pathway inhibition, regulation of IL-6 signaling in adoptive T-cell therapy, AhR/IL-22 modulation, and FXR activation. Further translational studies are needed to validate SOCS3 as a biomarker and therapeutic target in CRC.",
        "42525181": "ID: 42525181\nTitle: Age-related differences in liver damage and inflammation after femoral osteotomy.\nAbstract: Fractures of long bones such as the femur are a common and serious health concern in the elderly, triggering immune responses essential for healing but also affecting remote organs like the liver. With age, the risk of fractures and immune imbalance increases, raising the likelihood of organ damage, infections, and mortality. To better understand age-dependent hepatic responses to bone injury, this study investigates early immune responses in the liver following femoral osteotomy, used here as a reproducible model of fracture. In a mouse model, young (17-26\u00a0weeks old) and aged (64-72\u00a0weeks old) male C57BL/6J mice received a femoral osteotomy with external fixation (Fx) or a corresponding sham procedure. After 24\u00a0h, inflammation, apoptosis, tissue damage, and immune responsiveness of the liver were analyzed. Aged sham animals exhibited a higher inflammatory state in sham-operated animals (neutrophil infiltration, tumor necrosis factor (TNF), interleukin (IL)-1b, chemokine (C-X-C motif) ligand 1 (CXCL1)), without corresponding increases in caspase-3-positive cells, activation of c-Jun N-terminal kinase (JNK), expression of sirtuin (SIRT) 1 or 3, or the receptor for advanced glycation end products (RAGE). Fx did not increase liver damage in young mice but showed a trend toward greater damage in aged mice. Fx significantly increased hepatic neutrophil infiltration and CXCL1 as well as TNF concentrations in both age groups. Aged mice showed weaker activation of pro- and anti-inflammatory signaling pathways after osteotomy, with reduced RAGE expression, JNK activation, and less pronounced induction of SIRT1 and SIRT3. In summary, femur osteotomy induced liver inflammation in both young and aged animals; however, older animals exhibit higher apoptosis and a superimposed inflammatory response on top of already elevated baseline inflammation in sham conditions. Further, they did not adequately activate key regulators like RAGE, SIRT1, and JNK, which coordinate inflammation and repair. Observed dysregulations may underlie the increased vulnerability to post-traumatic complications in the elderly. Understanding these age-related deficits is essential to improving therapeutic strategies.",

Sixty female mice were randomized into three groups (20 mice each): control (CON, 500\u00a0m, conventional housing for 14 d), 7 d hypoxic exposure (LO1) and 14 d hypoxic exposure (LO2). LO1 and LO2 were kept in a low-pressure hypoxic chamber simulating 5500\u00a0m. Serum reproductive hormones (AMH, FSH, LH, E2) and oxidative stress markers were detected; ovarian indices were calculated and ovarian histopathology examined. Additionally, transcriptome sequencing and functional enrichment analysis of differentially expressed genes were conducted on ovarian tissues. Compared with CON, LO1 and LO2 showed markedly decreased serum AMH, LH and E2 (P\u2009<\u20090.01), sharply elevated FSH (P\u2009<\u20090.001), increased malondialdehyde (P\u2009<\u20090.001), reduced superoxide dismutase activity (P\u2009<\u20090.01), first increased then decreased total antioxidant capacity (P\u2009<\u20090.001), and lower ovarian index (P\u2009<\u20090.01). Histology showed ovarian atrophy and ischemic congestion, with fewer primary, secondary and mature follicles (P\u2009<\u20090.05) and more atretic follicles in LO2 (P\u2009<\u20090.05). Transcriptome sequencing found 234 significantly differentially expressed genes, whose co-differentially expressed ones were enriched in oxygen transport/oxidative stress and steroid hormone synthesis pathways. Acute high-altitude hypoxia impairs ovarian reserve function and disrupts follicular development in female mice, potentially through oxidative stress imbalance and dysregulation of genes involved in steroid hormone synthesis pathways.",

However, only a few studies have investigated ACR-induced liver injury. As a naturally occurring flavonoid widely distributed across the plant kingdom, rutin (Rut) possesses notable pharmacological properties. This study aimed to demonstrate its therapeutic potential in mitigating ACR-induced hepatic injury in rats. Accordingly, an intervention model was established to explore the mechanistic basis of the protective effects of Rut against ACR-induced liver injury. The experimental design comprised five cohorts (n\u2009=\u200910), consisting of 50 male Sprague-Dawley rats randomly assigned to each group: (1) Control (0.5% CMC-Na\u2009+\u2009ddH2O), (2) ACR (20\u00a0mg/kg/day via gavage), (3) Rut-L (100\u00a0mg/kg)\u2009+\u2009ACR, (4) Rut-M (200\u00a0mg/kg)\u2009+\u2009ACR, and (5) Rut-H (400\u00a0mg/kg)\u2009+\u2009ACR. Interventions lasted for 21 days. The body weights of the animals were monitored daily. The liver coefficient (liver weight/body weight) was calculated after euthanasia. Commercial assay kits were used to determine serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities and hepatic Superoxide Dismutase (SOD), Glutathione (GSH), and Malondialdehyde (MDA) levels. Histopathological changes were assessed using Hematoxylin and eosin and Masson staining. Tumor Necrosis Factor-\u03b1 (TNF-\u03b1) and cleaved caspase-3 expression levels were analyzed using immunohistochemistry. Compared with the Control group, ACR exposure attenuated the rate of body weight accrual (P\u2009<\u20090.05) and the liver-to-body weight ratio (P\u2009<\u20090.05), elevated serum ALT (\u219134.8%, P\u2009<\u20090.05) and AST (\u219147.7%, P\u2009<\u20090.05), decreased hepatic SOD (\u219348.9%, P\u2009<\u20090.05) and GSH (\u219317.7%, P\u2009<\u20090.05), and increased MDA (\u219138.8%, P\u2009<\u20090.05). High-dose Rut reversed these effects by increasing body weight gain (P\u2009<\u20090.01), liver coefficient (\u219129.4%, P\u2009<\u20090.05), SOD (\u219132.1%, P\u2009<\u20090.05), and GSH (\u219112.1%, P\u2009<\u20090.05), while reducing ALT (\u219322.9%, P\u2009<\u20090.01), AST (\u219316.8%, P\u2009<\u20090.01), and MDA (\u21939.0%, P\u2009<\u20090.05) levels. Histopathological analysis demonstrated reduced hepatocyte necrosis and collagen deposition in the Rut-treated group. Immunohistochemistry revealed that ACR increased TNF-\u03b1 (\u2191121.4%, P\u2009<\u20090.001) and cleaved caspase-3 (\u219197.8%, P\u2009<\u20090.001) expression, which was suppressed by Rut (TNF-\u03b1: \u219348.2%, P\u2009<\u20090.01; cleaved caspase-3: \u219339.5%, P\u2009<\u20090.01). The effect sizes (Cohen's d) ranged from 1.2 to 3.6, indicating robust effects. Rut exhibits a marked protective effect against ACR-induced hepatic injury. Therefore, Rut may be considered a potential agent for preventing ACR-induced liver injury in rats.",

In oral squamous cell carcinoma (OSCC), dysregulated autophagy may promote chemoresistance by supporting metabolic adaptation, removing damaged cellular components, and limiting treatment-induced cell death. Its effects are nevertheless context dependent, as autophagy can also interact with apoptosis, ferroptosis, and other cytotoxic pathways. This review summarizes molecular mechanisms linking autophagy to OSCC chemoresistance, focusing on non-coding RNAs, p53/TP53, BECN1, ATG-related proteins, oncogenic signaling networks, and emerging biomolecular-condensate mechanisms. It also evaluates therapeutic strategies, including early- and late-stage autophagy inhibition, mTOR-targeted modulation, metabolic interventions, genetic approaches for mechanistic validation, ferroptosis-autophagy combinations, and nanotechnology-assisted delivery systems. Although promising effects have been reported in cell lines, drug-resistant derivatives, cancer stem cell-like populations, and xenograft models, OSCC-specific clinical evidence remains limited. Future progress will require rigorous assessment of autophagic flux, careful interpretation of related head and neck squamous cell carcinoma evidence, biomarker-guided patient stratification, and validation in clinically relevant models. Integrating autophagy biology with molecular stratification and rational combination therapy may help overcome chemoresistance in OSCC.",

It is the main cause of chronic low back pain. Its pathogenesis is closely related to cellular aging and immune inflammation. Aging nucleus pulposus cells release pro-inflammatory factors such as IL-6 and TNF-\u03b1 through the secretion of senescence associated secretory phenotype (SASP), recruiting M1 macrophages to infiltrate and forming a vicious cycle of \"aging inflammation matrix destruction.\" This study systematically analyzed the molecular mechanism by which kaempferol improves IVDD through multi-target regulation by integrating bioinformatics analysis, animal experiments, and cell models. Bioinformatics screening revealed significant abnormal expression of genes such as AURKB, CCNB1, AXL, NEK6, and PTK2 in IVDD degenerated tissues. Downregulation of CCNB1 induced G2/M phase arrest by inhibiting CDK1 activity, while activation of GSK3B inhibited the Wnt signaling pathway by phosphorylating \u03b2-catenin, exacerbating ECM catabolism. Proteomics further confirms that the NOX4 mediated ROS-p38 MAPK pathway promotes cell apoptosis and SASP secretion. Immune infiltration analysis showed that M1 macrophages were significantly enriched in degenerated intervertebral discs, and their secreted IL-6 and TNF-\u03b1 amplified the inflammatory cascade by activating the NF-\u03ba B pathway. Animal experiments have shown that intervention with kaempferol can partially restore the intervertebral disc height index (DHI), downregulate the levels of IL\u20111\u03b2 and TNF\u2011\u03b1, upregulate the expression of CCNB1 and AURKB (which were downregulated in the IVDD model), thereby alleviating G2/M phase arrest and promoting cell cycle progression, inhibit AXL and PTK2, and reduce macrophage infiltration. Mechanistically, kaempferol inhibits NOX4 activity by clearing ROS, blocking the vicious cycle of oxidative stress\u2011inflammation; by regulating the NEK6/NF\u2011\u03baB axis, the expression of MMP\u20113 and ADAMTS\u20114 is reduced, delaying ECM degradation; and improve the immune microenvironment by promoting macrophage polarization towards the M2 phenotype. In addition, kaempferol can reverse the metabolic imbalance mediated by GSK3B. This study reveals for the first time that kaempferol upregulates core gene networks such as AURKB and CCNB1 while suppressing AXL through the \"anti\u2011inflammatory anti\u2011aging\" dual pathway, thereby breaking the \"aging\u2011immunity\" crosstalk and restoring cell cycle homeostasis, providing a new strategy for natural compound intervention in IVDD treatment.",

Norcantharidin (NCTD), a small-molecule compound with reported anti-inflammatory, antioxidant, and antifibrotic properties, has attracted attention as a potential therapeutic agent. To investigate the protective effects of NCTD against AIPF in rats. Eighteen rats were randomly divided into three groups (n\u2009=\u20096 each): a negative control group receiving vehicle, an amiodarone group, and an NCTD-treated group receiving 0.1\u00a0mg/kg intraperitoneally for six weeks. Pulmonary fibrosis was induced by oral administration of 50\u00a0mg/kg amiodarone for five weeks. Lung injury was assessed using hematoxylin and eosin staining and semi-quantitative scoring, collagen deposition was evaluated by Masson's trichrome staining, and immunohistochemistry was performed for fibronectin and \u03b1-smooth muscle actin (\u03b1-SMA). Molecular and biochemical markers including tumor necrosis factor (TNF)-\u03b1, \u03b2-catenin, interleukin (IL)-1\u03b2, malondialdehyde (MDA), and glutathione (GSH) were measured, while glycogen synthase kinase (GSK)-3\u03b2 was assessed by Western blot, and miRNA-30a by quantitative PCR. Amiodarone significantly increased lung injury scores, collagen deposition, \u03b1-SMA, fibronectin, TNF-\u03b1, IL-1\u03b2, MDA, GSK-3\u03b2, and \u03b2-catenin, while reducing GSH and miRNA-30a levels.

Histologically, NCTD preserved alveolar architecture, reduced peribronchiolar inflammation, and normalized collagen distribution. These results demonstrate that NCTD exerts potent antifibrotic, anti-inflammatory, and antioxidant effects in AIPF, likely through modulation of oxidative stress, inflammatory cytokines, microRNA expression, and the GSK-3\u03b2/\u03b2-catenin signaling pathway, highlighting its potential as a therapeutic agent for drug-induced lung injury.",

Paired human donor corneas were cultured for 28\u00a0days in \u03b1-MEM-based medium supplemented with either 2% FBS or 2% UCB-PL. Endothelial morphology, cell density, viability, and mosaic regularity were assessed at predefined time points. Metabolic activity was evaluated by measuring pH, glucose, and lactate concentrations in the culture media. Endothelial integrity, apoptosis, and proliferation were analyzed by whole-mount immunofluorescence staining for ZO-1, Na\u207a/K\u207a-ATPase, caspase-3, and Ki-67. Corneas stored in UCB-PL-supplemented medium demonstrated endothelial morphology, cell density decline, and viability comparable to those observed in FBS-supplemented medium throughout the culture period. No significant differences were detected between groups at any time point. Metabolic analysis showed sustained glucose availability and expected lactate accumulation in both media, without evidence of nutrient depletion. Immunofluorescence confirmed preserved endothelial junctional organization and pump protein expression, with no signs of endothelial apoptosis or proliferation. In this pilot feasibility study, UCB-PL supported preservation of human corneal endothelial morphology and endothelial-associated protein expression during organ culture and demonstrated similar trends to FBS. These findings support further investigation of UCB-PL as a potential xeno-free alternative for corneal storage media.",

This study evaluated the toxicological responses of Synechococcus sp. D24 and Scenedesmus sp. T24 exposed to chlorpyrifos at 0.01-10\u00a0mg/L. Growth inhibition, chlorophyll a content, photosynthetic efficiency (Fv/Fm), and superoxide dismutase (SOD) activity were assessed to determine physiological stress. Scenedesmus sp. T24 showed high sensitivity, exhibiting strong reductions in growth, chlorophyll a, and Fv/Fm even at low concentrations, accompanied by a continual decline in SOD activity. In contrast, Synechococcus sp. D24 demonstrated greater tolerance, with moderate physiological alterations and a biphasic SOD response indicating possible adaptation at low exposure levels. The EC\u2085\u2080 values (0.95\u00a0\u00b5g/L and 9.5\u00a0\u00b5g/L, respectively) confirmed clear species-specific differences.

Despite its long-standing ethnomedicinal use, a comprehensive mechanistic understanding of its role across different types of arthritis remains limited. This review aims to systematically evaluate the pharmacological effects and molecular mechanisms of rutin in rheumatoid arthritis, gouty arthritis, osteoarthritis, and Psoriasis, integrating ethnopharmacological relevance with modern experimental evidence. A comprehensive literature search was conducted across databases including PubMed, Scopus, and Web of Science. Preclinical in vivo, in vitro, and mechanistic studies investigating rutin in arthritic models were included. Data were synthesized to identify key molecular targets, signaling pathways, and therapeutic outcomes. Rutin demonstrated significant anti-arthritic effects across multiple models. In rheumatoid arthritis, rutin reduced inflammatory cytokines (TNF-\u03b1, IL-6), oxidative stress, and joint damage via inhibition of NF-\u03baB and iNOS signaling. In gout, rutin lowered uric acid levels by inhibiting xanthine oxidase and suppressing NLRP3 inflammasome activation. In osteoarthritis, rutin protected cartilage integrity by modulating extracellular matrix degradation and regulating NF-\u03baB/MAPK, SIRT1, and RhoA/ROCK pathways. In Psoriasis, rutin attenuated keratinocyte proliferation and inflammation through JAK/STAT inhibition and activation of the Nrf2 antioxidant pathway. Additionally, advanced delivery systems such as nanoparticles and hydrogels enhanced its bioavailability and therapeutic efficacy. Rutin exhibits multi-target anti-arthritic potential supported by both traditional use and modern pharmacological evidence. Its ability to modulate key inflammatory and oxidative pathways highlights its potential as a phytopharmaceutical candidate for arthritis management. Further clinical validation and standardization are required to translate these findings into therapeutic applications.",

Arbutin, a naturally occurring glycoside with known antioxidant and anti-inflammatory properties, has the potential to modulate neurochemical alterations following brain injury. The present study was designed to evaluate the neuroprotective effects of arbutin in a zebrafish model of TBI induced by a novel non-invasive mechanical impact method termed \"force-induced TBI.\" Adult zebrafish were randomly divided into seven groups (n\u2009=\u200914 per group): normal control, TBI control, arbutin per se, arbutin-treated groups (25, 50, and 100\u00a0mg/kg, i.p.), and a co-treatment group receiving arbutin (100\u00a0mg/kg) co-administrated with chrysin (25\u00a0mg/kg), a known modulator of the Nrf2/NF-\u03baB signaling pathway. Behavioural assessments, including the open field test, novel tank diving test (NTDT), T-maze, and novel object recognition test (NORT), were conducted on days 1, 4, and 7 to evaluate locomotion activity, anxiety-like behaviour, spatial memory, and recognition ability, respectively. Following behavioural evaluation, brain tissues were analysed for oxidative stress markers (MDA, nitrite, GSH, and SOD), neurotransmitter levels (GABA and glutamate), pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, and IL-6), and histopathological alterations. Immunohistochemical analysis of Nrf2 and NF-\u03baB was also performed. The results demonstrated that arbutin significantly improved behavioural performance, restored oxidative balance, normalized neurotransmitter levels, and attenuated neuroinflammatory responses. Furthermore, arbutin treatment was associated with increased Nrf2 immunoreactivity and reduced NF-\u03baB immunoreactivity in a dose-dependent manner. The co-treatment with chrysin also exhibited protective effects, supporting its potential modulatory role in oxidative stress and these effects are associated with modulation of oxidative stress, neuroinflammation, neurotransmitter imbalance, and Nrf2/NF-\u03baB immunoreactivity. These findings suggest that arbutin possesses neuroprotective potential against secondary brain injury and is associated with modulation of oxidative stress, inflammatory responses, and Nrf2/NF-\u03baB immunoreactivity.",

Tremors, stiffness, bradykinesia/akinesia, and postural instability are its primary motor symptoms; nevertheless, the clinical features also include non-motor and additional motor symptoms. Kr\u00fcppel-like factor 4 (KLF4), a zinc finger transcription factor, is present in several human tissues and performs a range of cell-dependent regulatory actions. Various neurological diseases, such as PD, Alzheimer's disease (AD), and Huntington's disease (HD), have been linked to KLF4, which regulates some neurophysiological and neuropathological processes in the brain. Recent data indicate that KLF4 plays a crucial regulatory role in the neurophysiological and neuropathological processes underlying PD, suggesting that it might be a viable therapeutic target for neurodegenerative diseases. This review focuses on the potential molecular mechanism underlying KLF4-mediated neuroinflammation, oxidative stress, mitochondrial dysfunction, and apoptosis. KLF4-mediated pathways are clarified by the information gathered here, and targeting them appears to be a viable therapeutic strategy for treating PD. Nevertheless, there is insufficient information on this subject, and more investigations are needed to fully understand the translational significance of the KLF4-oriented therapeutic strategy in PD.",

This condition is primarily driven by excessive reactive oxygen species (ROS) and dysregulation of Caspase-dependent apoptosis. Quercetin (QUE), a natural antioxidant flavonoid, exhibits radioprotective potential; however, the key signaling pathways it employs to regulate radiation-induced apoptosis remain to be elucidated. In vitro studies, IEC-6 cells (1-10\u00a0\u00b5g/mL QUE pretreatment followed by 0-8\u00a0Gy X-ray exposure) were conducted to analyze proliferation, clonogenic survival, ROS levels, apoptosis, and expression of RIII-related proteins and genes. Network pharmacology identified 47 overlapping targets associated with QUE and RIII, with AKT1 and CASP3 identified as hub targets, and the PI3K-AKT pathway recognized as a key regulatory pathway. A Caspase-3/7 inhibitor (HY-103346, H10) and AutoDock-Vina docking analysis were used to explore the involvement of Caspase-3-related apoptotic signaling. In vivo experiments using Drosophila melanogaster (W1118) involved groups subjected to control, 50\u00a0Gy irradiation alone, or 50\u00a0Gy combined with 1/5/10/50 \u00b5g/mL QUE. Lifespan, locomotor capacity, and intestinal ROS levels were assessed, including validation with DCP-1RNAi transgenic flies (DCP-1: Drosophila Caspase-3 homolog). In vitro findings revealed that QUE enhanced the viability of irradiated IEC-6 cells, reduced ROS and apoptosis, upregulated anti-apoptotic markers (p-AKT, p-PI3K and p-mTOR), and downregulated pro-apoptotic markers (cleaved-Caspase-3 and Cytochrome C), while H10 inhibited the effects of QUE. Molecular docking suggested a potential interaction between QUE and Caspase-3 through hydrogen bonds and hydrophobic interactions to inhibit its activation. In vivo, pre-irradiation gavage of 10\u00a0\u00b5g/mL QUE mitigated RIII in Drosophila, an effect that was abolished in DCP-1 knockdown flies. In summary, QUE protects against RIII by scavenging ROS and modulating apoptosis-related signaling, with evidence supporting the involvement of the PI3K-AKT/Caspase-3 axis, with the PI3K-AKT/Caspase-3 axis identified as central to these protective effects. This study underscores the clinical potential of QUE for RIII and offers insights into the targeting of apoptosis for radioprotection.",

Although perioperative nerve injury is increasingly recognised, the contribution of local-anaesthetic neurotoxicity, the relative toxicity of different agents and concentrations, and the influence of patient-related risk factors remain incompletely defined. This evidence-based narrative review synthesises experimental and clinical data on peripheral nerve neurotoxicity associated with local anaesthetics and discusses implications for clinical practice and future research. A prospectively registered search was conducted across major biomedical databases for studies published between 1990 and 2024. Experimental evidence consistently demonstrates dose-dependent and time-dependent neurotoxicity for all clinically used local anaesthetics, characterised by ultrastructural damage, oxidative stress, mitochondrial dysfunction and activation of apoptotic and intracellular signalling pathways. Relative toxicity varies between agents and concentrations, with lidocaine and bupivacaine often appearing more potent than ropivacaine or chloroprocaine in preclinical models, while findings for articaine remain heterogeneous. Diabetic and metabolically compromised nerves exhibit increased susceptibility, supporting a 'two-hit' model of injury. In contrast, clinical evidence directly linking specific agents, concentrations or exposure durations to permanent peripheral nerve injury is limited, and such injuries are typically multifactorial. Overall, chemical neurotoxicity should be considered one component of a broader perioperative risk profile. Risk mitigation should prioritise avoidance of intraneural injection, adherence to recommended doses and cautious use of high concentrations or prolonged exposure, particularly in vulnerable nerves. Further research should integrate mechanistic and clinical outcomes while accounting for patient-level risk factors.",

To deliver drugs specifically to cancer cells that overexpress CD44, this study developed hyaluronic acid (HA)-functionalized dextran (DEX) polymeric nanoparticles (ETP-DEX-HA-NPs). Optimised nanoparticles (174.7\u2009\u00b1\u20093.2\u2009nm, -12.83\u2009\u00b1\u20091.1\u2009mV) demonstrated significant entrapment efficiency (62.75\u2009\u00b1\u20092.32%) and drug loading (55.64\u2009\u00b1\u20093.86%), with partial amorphization validated by FTIR, XRD, Raman, NMR, and DSC analyses.

It facilitated CD44-mediated uptake, enhanced apoptosis, induced G2/M arrest, elevated ROS production, and inhibited migration while preserving biocompatibility. Network pharmacology and molecular docking identified key interactions with CRC-related targets (e.g., TOP2A, BCL2).

Preeclampsia, a hypertensive disorder that affects 5%-8% of pregnancies, is associated with immune dysregulation, oxidative stress, and impaired placental remodeling. In this study, we investigated the distribution of CD14+ and CD11b+ cells and the production of reactive oxygen species (ROS) in placental tissues from healthy pregnancies and preeclampsia cases, from areas near the umbilical cord and the delivery channel and divided into maternal, maternal/fetal and fetal zones, of each area. Immunofluorescence analysis revealed that in healthy placentas, CD14+ macrophages were heterogeneously distributed with enrichment in the fetal section near the delivery channel, whereas in preeclamptic placentas these cells accumulated predominantly in the umbilical cord region. No significant differences were observed for CD11b+ cells, although a tendency toward increased numbers was noted in preeclamptic tissues. ROS analysis showed no statistically significant changes, but preeclamptic placentas exhibited weaker fluorescence intensity, indicating reduced ROS activity. These findings suggest that altered CD14+ and CD11b+ cells localization, together with diminished ROS signaling, may contribute to the pathophysiology of preeclampsia by impairing immune regulation and placental vascular remodeling.",

The two-spotted spider mite (Tetranychus urticae) is a generalist herbivore that feeds by sucking the contents of mesophyll cells, a feeding strategy distinct from that of phloem-feeding insects. Here, we show the unexpected differential expression of apolipoprotein D (ApoD) genes during feeding when mites are transferred to different host plant species, as well as extreme gene family expansion (64 ApoD paralogs, the largest reported in any organism). We find that ApoD proteins protect mites against reactive oxygen species (ROS) during feeding, and we identify a dual-layer mechanism by which ApoD proteins counteract plant ROS defenses during ingestion and digestion. First, the salivary protein TuApoD2 is secreted during the ingestion of mesophyll cell contents, where it interacts with glycolate oxidase 2 (GOX2) to inhibit H2O2 generation. After ingestion, TuApoD33 in the gut cells also interacts with GOX2 to maintain the inhibition of H2O2 generation. These findings suggest that the evolutionary expansion of the ApoD gene family is a key component of the molecular arms race between herbivorous mites and host plants.",

High glucose intake promotes Th17 differentiation and autoimmunity, but its effects on autoimmune testicular inflammation remain unclear. To determine whether chronic high glucose supplementation exacerbates experimental autoimmune epididymo-orchitis (EAEO), impairs spermatogenesis, and drives CD4+ T-cell dysregulation, particularly Th17 polarization, in the reproductive tract. EAEO was induced in male C57BL/6 mice with or without chronic 10% glucose supplementation in drinking water. Sperm parameters, ROS levels, apoptosis, and histopathology were evaluated. CD4+ T-cell subsets (Th1, Th17, Treg, TNF-\u03b1+ effector memory) were quantified by flow cytometry in testis, epididymis, spleen, and testicular inguinal lymph nodes (iLN) at days 30, 60, and 90 post-immunizations. High glucose intake accelerated EAEO progression, markedly worsening sperm concentration and motility, elevating sperm ROS, increasing germ cell apoptosis, and causing severe histopathological damage. In the reproductive tract, glucose induced an upward trend of CD4+ T cells and late-phase selective Th17 skewing (days 60-90), with significant IL-17A+CD4+ Teff increases and accompanying TNF-\u03b1+CD4+CD44+ Teff upregulation, while IFN-\u03b3+ Th1 responses remained modest. These pro-inflammatory changes were strictly localized, with no significant Th17, Th1, Treg, or TNF-\u03b1 alterations in spleen or iLN. Chronic high glucose exacerbates EAEO by intensifying oxidative stress, apoptosis, and tissue injury while promoting a late-phase, tissue-restricted Th17-biased CD4+ T-cell response in the testis and epididymis. These findings reveal a metabolic-immune axis that may accelerate immune-mediated male subfertility via localized Th17 mechanisms.",

Multivariate logistic regression, subgroup analyses, and smoothed curve fitting models were applied to investigate the relationship between oxidative balance scores and gallstone outcomes, adjusting for age, sex, race, and health conditions.ResultsHigher oxidative balance score was significantly associated with lower risks of gallstones and gallbladder surgery. Each 1-unit increase in the oxidative balance score corresponded to a 2.6% reduction in gallstone risk (odds ratio\u2009=\u20090.974; 95% confidence interval: 0.958, 0.990) and a 3.3% reduction in gallbladder surgery risk (odds ratio\u2009=\u20090.967; 95% confidence interval: 0.950, 0.983). Subgroup and dose-response analyses confirmed these consistent, negative associations.ConclusionsHigher oxidative balance score is independently associated with a reduced prevalence of gallstones and gallbladder surgery. Furthermore, maintaining a higher antioxidant status may play a role in the management of gallstone disease risk.",

Although caused by reduced dosage of the polycystin proteins, the disease phenotype arises from a broad disruption of epithelial physiology rather than a single linear pathway. Loss of polycystin function destabilizes epithelial homeostasis and sensitizes cyst lining cells to proliferative and secretory cues. A central consequence is the emergence of a self reinforcing signaling environment in which cyclic AMP, Ca2+, and purinergic pathways amplify one another, promoting chloride driven fluid secretion and epithelial proliferation. In parallel, cyst epithelia exhibit disturbed cell turnover, including altered proliferation, apoptosis, autophagy, and ferroptotic stress, which reshape luminal architecture and sustain a pro secretory microenvironment. Metabolic reprogramming, characterized by enhanced glycolysis, mitochondrial dysfunction, and redox imbalance, provides energetic support for these processes and further strengthens proliferative and secretory signaling. Hypoxia inducible factor 1\u03b1 (HIF 1\u03b1) integrates hypoxic, metabolic, and mechanical cues into transcriptional programs that reinforce cyst expansion. This review synthesizes these interconnected mechanisms and highlights potential therapeutic strategies, including restoration of polycystin expression, modulation of cAMP and purinergic signaling, inhibition of chloride secretion, metabolic targeting, and HIF 1\u03b1 pathway intervention. Together, these insights support a model in which cyst growth arises from mutually reinforcing signaling, metabolic, and transcriptional programs. Effective disease modification will likely require multi nodal therapeutic approaches that address this integrated network.",

Emerging evidence indicates that susceptibility to ferroptosis is not governed solely by cytosolic signaling pathways, but instead results from the coordinated actions of multiple intracellular organelles, including mitochondria, lysosomes, the endoplasmic reticulum (ER), and lipid droplets. Mitochondria play dual roles in ferroptosis by integrating metabolic activity, redox balance, and mitochondrial quality control; thereby influencing reactive oxygen species generation and lipid peroxidation. Lysosomes regulate ferroptotic sensitivity through iron mobilization, inter-organelle iron transfer, lysosomal redox activity/lipid peroxidation, lysosomal signaling hub, and ferritinophagy. The ER contributes to ferroptosis by coordinating lipid biosynthesis, membrane polyunsaturated fatty acid composition, and unfolded protein response signaling, as well as by disrupting antioxidant defenses and iron homeostasis, especially during ER stress. Lipid droplets function as dynamic lipid reservoirs that buffer oxidizable fatty acids or, upon mobilization, supply substrates that fuel ferroptosis-associated lipid peroxidation. Here, we provide a comprehensive review of current mechanistic insights and recent advances in organelle-specific regulation and inter-organelle crosstalk during ferroptosis, highlighting emerging therapeutic opportunities and key experimental challenges. An integrated understanding of this multi-organelle regulatory network is essential for modulating ferroptosis in human diseases.",

Previous studies have demonstrated an association between increased level of iron in the lung and aging and age-related lung diseases including pulmonary fibrosis and asthma in the elderly (AIE). However, the mechanisms underlying the accumulation of iron with aging or AIE, or the cell types involved, remain understudied. In the context of asthma, airway smooth muscle is a key cell type contributing to contractility as well as airway remodeling (proliferation, fibrosis). In this study we characterized iron level and regulation in human (hASM) from young (<45 yr), old (\u226565 yr) and AIE (\u226565 yr) male/female patients, and investigated the contribution of iron overload in hASM to airway remodeling. Cells were treated with ferric ammonium citrate (FAC) (100 \u03bcM; 72h) or iron chelator deferoxamine (DFO) (100 \u00b5M; 72h). Basal levels of intracellular ferrous iron (Fe2+) were determined using the fluorescent dye FerroOrange. Cell lysates were analyzed for iron accumulation, antioxidant, lipid peroxidation, and extracellular matrix (ECM) markers, and cell proliferation was assessed. We found that iron accumulates with aging, but surprisingly decreases with AIE. hASM from AIE patients showed activated antioxidant pathways and lipid peroxidation, while FAC-exposure impaired iron metabolism and enhanced ECM deposition. Iron depletion mitigated the antioxidant response, lipid peroxidation, cell proliferation, ECM production. These findings suggest that iron metabolism in hASM contributes to cell hyperplasia and ECM, while in aging and particularly AIE, counter-regulatory changes in iron metabolism and antioxidant pathways occur, overall promoting airway remodeling.",

In this study, we identify Arachidonate 12-lipoxygenase (ALOX12) as a previously unrecognized ferroptosis-related tumor suppressive regulator with significant diagnostic and prognostic value in OC. By integrating Weighted Gene Co-expression Network Analysis (WGCNA), machine learning algorithms, and survival modeling, and validating our findings through in vitro and in vivo experiments, transcriptomic profiling, and biochemical assays, we systematically characterized the biological and mechanistic roles of ALOX12. Our analysis revealed that ALOX12 is markedly downregulated in OC tissues, with its low expression correlating with poor clinical outcomes. Functional experiments further demonstrated that ALOX12 suppresses OC cell proliferation, invasion, and migration, while promoting apoptosis and ferroptosis-associated lipid peroxidation. Mechanistically, transcriptome sequencing and protein assays pinpointed MAPK signaling as a key pathway modulated by ALOX12. Additionally, our experiments revealed that ALOX12 exerts its effects by regulating HSPA6 expression. Collectively, these findings highlight ALOX12 as a promising biomarker and potential therapeutic target, offering new insights into ferroptosis-associated signaling networks and their implications for improving the management of OC.",

However, its transgenerational effects following embryonic egg exposure on avian development and chick health remain poorly characterized.This study employed embryonic egg injection and multi-omics approaches to evaluate the impacts of ZEN (0, 5, 50, or 500 \u03bcg/egg) administered to Hy-line Brown eggs on day 5 of incubation. ZEN exposure significantly decreased hatchability and initial chick weight. During the 20-day post-hatch period, it induced dose-dependent reductions in net weight, average daily gain, and average daily feed intake, while increasing the feed conversion ratio.Histopathology showed intestinal inflammation and structural damage, coupled with gut microbiota dysbiosis, notably an elevated abundance of pathogenic bacteria such as Escherichia coli. ZEN also caused liver injury, manifested by elevated serum biochemical indices, oxidative stress, and inflammatory responses. Hepatic metabolomics revealed pronounced alterations in metabolites and pathways associated with lipid metabolism, autophagy, and antioxidant defense.Correlation analyses indicated interconnections between gut microbiota dysbiosis and hepatic metabolic disturbances, suggesting mediation of ZEN developmental toxicity via the gut-liver axis.

Here, we provide a global synthesis of the ecotoxicological responses of aquatic macrophytes to 2,4-D based on a PRISMA-guided systematic review of 86 peer-reviewed studies published between 1947 and 2025. A consistent gradient of species-specific sensitivity was observed across macrophyte growth forms. The submerged species Myriophyllum spicatum showed high susceptibility, with EC\u2085\u2080 values of 0.04-0.182 mg/L and marked growth inhibition at low concentrations, whereas floating species such as Lemna minor and Pontederia crassipes were more tolerant, requiring higher concentrations (7.08 to >100 and 8.1 mg/L, respectively) to produce comparable effects. Importantly, this sensitivity ranking was consistent across laboratory and field experimental settings. These interspecific differences likely reflect variation in herbicide uptake, translocation, and detoxification capacity associated with growth form. The overlap between EC\u2085\u2080 values for M. spicatum and regulatory thresholds for 2,4-D in surface waters suggests that current limits may be insufficient to protect sensitive submerged macrophyte communities. Regarding remediation, L. minor and Salvinia natans emerged as the most promising candidates for phytoremediation, while P. crassipes showed limited capacity to reduce herbicide concentrations in water. Despite advances, no study directly compared oxidative stress biomarkers between submerged and floating species, representing a critical gap in understanding the biochemical basis of the sensitivity gradient. Overall, this synthesis highlights the need to account for taxon-dependent sensitivity when evaluating the ecological risks of 2,4-D and provides a basis for improving regulatory frameworks and management of herbicide contamination in freshwater ecosystems.",

Biological evaluation identified NS06 as the best-balanced analogue, with IC50 values of 1.49 and 1.41\u00a0\u03bcM against MDA-MB-231 and HCT116 cells, respectively. Mechanistic studies showed that NS06 bound STAT3 in vitro (SPR, KD\u00a0=\u00a05.82\u00a0\u03bcM), suppressed STAT3 phosphorylation, and inhibited HDAC1, HDAC3, and HDAC6 with IC50 values of 129.1, 451.2, and 230.4\u00a0nM, respectively, while showing limited inhibition of HDAC4 and HDAC11 in the primary screen. NS06 also increased histone H3 acetylation, induced apoptosis, and inhibited migration and colony formation. In addition, NS06 retained antiproliferative activity in a 3D tumor spheroid model and showed improved Caco-2 permeability together with moderate liver microsomal stability (t1/2\u00a0\u2248\u00a048.6\u00a0min in rat liver microsomes). Docking and 100-ns molecular dynamics simulations further supported chemically plausible binding modes in the HDAC1 catalytic pocket and the STAT3 SH2 domain. Overall, these findings support niclosamide as a tractable scaffold for mechanism-driven STAT3/HDAC dual-target inhibitor design and identify NS06 as a promising lead for further optimization against solid tumors.",
        "42526136": "ID: 42526136\nTitle: The role and mechanism of S1PR2 in endothelial dysfunction and aortic lesions during gestational diabetes mellitus.\nAbstract: This study investigated the role of S1PR2 in gestational diabetes mellitus (GDM)-associated endothelial dysfunction and aortic lesions, and its relationship with advanced glycation end-products (AGEs) and the RhoA/ROCK1/eNOS pathway. Placental tissues and serum samples were collected from patients with GDM and healthy pregnant women to assess S1PR2 expression and AGEs levels. HUVECs were treated with high glucose (HG), osmotic control medium, JTE-013, S1PR2 siRNA, S1PR2 overexpression plasmid, or AGEs-BSA. Cell viability, apoptosis, endothelial permeability, reactive oxygen species (ROS), nitric oxide (NO), and RhoA/ROCK1/eNOS pathway proteins were examined. A GDM rat model was established using a high-fat diet combined with low-dose streptozotocin, followed by pyridoxamine or JTE-013 treatment. S1PR2 expression and serum AGEs levels were increased in GDM samples. HG impaired HUVEC viability, increased apoptosis, permeability, and ROS production, reduced NO content, activated RhoA/ROCK1 signaling, and decreased eNOS phosphorylation, while osmotic control showed no obvious effect. JTE-013 and S1PR2 knockdown alleviated endothelial injury, whereas S1PR2 overexpression aggravated these changes. AGEs-BSA upregulated S1PR2, increased ROS, and decreased NO. In GDM rats, pyridoxamine and JTE-013 reduced serum AGEs, aortic lipid deposition, vascular injury, and S1PR2/RhoA/ROCK1 pathway activation. S1PR2 promotes high-glucose-induced endothelial dysfunction and GDM-related aortic lesions, partly through the RhoA/ROCK1/eNOS axis. AGEs may contribute to S1PR2 upregulation, suggesting that AGE formation and S1PR2 are potential targets for GDM-associated vascular injury.",
        "42526143": "ID: 42526143\nTitle: Phosphatidylserine lipids reduce the adsorption of chondroitin sulphate at the membrane surface.\nAbstract: Hypothesis Chondroitin sulphate (CS) is a linear polysaccharide typically found on the surface of cells and contributing to the structure of the extracellular matrix. Because of its proximity to the plasma membrane, the outermost cellular barrier, CS can interact with the phospholipids forming the structural scaffold of this cellular membrane. We hypothesise that the lipid composition of the plasma membrane, and specifically the exposure of phosphatidylserine (PS) lipids (an event that is detected in cancer cells and also associated to apoptosis and inflammation), affects the structural conformation of CS at the cell surface. Experiments We combined experimental data obtained with different techniques, i.e., quartz crystal microbalance with dissipation monitoring, neutron reflectometry and infrared spectroscopy, with molecular dynamics (MD) simulations to investigate the adsorption of CS at the surface of lipid bilayers prepared with either phosphatidylcholine (PC) lipids or a mixture of PC and PS lipids. Experiments were designed to identify the molecular groups that are involved in the CS-lipid interaction. Findings Our results indicate that CS adsorbs and remains stably attached to the lipid bilayer without PS lipids, due to stabilising interactions between the negatively charged sulphate groups on CS and positively charged choline groups within PC. The addition of POPS strongly reduces the CS-bilayer association: detecting experimentally CS chains attached to the bilayer was challenging, and the MD simulations suggest a weaker binding of CS to a PC-PS membrane."
