"abstract_text": "ID: 42518684\nTitle: Nanoparticles Navigating the Blood-Brain Barrier for Neurodegenerative Therapy.\nAbstract: The blood-brain barrier (BBB) blocks most drugs from entering the brain. Over 98% of small-molecule drugs and nearly all biologics fail to cross this barrier. Nanoparticles (NPs) provide multiple ways to bypass the BBB. These include receptor-mediated transcytosis, adsorptive-mediated transport, and intranasal delivery. NPs can also modify disease-related pathways. For example, they promote amyloid-\u03b2 clearance, reduce tau phosphorylation, and reprogram neuroimmune responses. Many preclinical studies have shown promising results in Alzheimer's, Parkinson's, and Huntington's diseases. However, no NP-based therapy has moved beyond early-stage clinical trials. Several issues remain unresolved. Direct comparisons between different NP platforms are lacking. The long-term toxicity of NPs in the brain is not well understood. Animal models also do not accurately reflect human disease. We suggest that future work should focus on standardized characterization, better predictive models, and clinical trial designs that address NP diversity. Researchers should also compare NP therapies with existing treatments in a rigorous manner."

However, concerns exist regarding potential toxicity and cost-effectiveness, limiting their clinical applications. In contrast, plant-derived exosomes (PDEs), as natural nanovesicles, offer significant advantages as drug delivery carriers due to their large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers. In this work, we established a ginseng-derived exosome (G-Exo)-based CDDP delivery system (G-CDDP) and evaluated its anti-tumor efficacy both in vitro and in vivo. The results demonstrated that G-CDDP effectively targeted tumor site, inhibiting the proliferation and migration and promoting apoptosis in U-87MG tumor cells. Notably, the amount of CDDP in G-CDDP required for achieving the same cytotoxic effect on tumor cells was 12.66 times lower than that of free CDDP. In U-87MG tumor-bearing mice, G-CDDP effectively targeted tumor sites and exhibited significant therapeutic effect. Collectively, these findings highlight the potent anti-tumor activity of G-CDDP at reduced CDDP dosage, positioning it as a promising and efficient alternative to conventional drug treatments in clinical settings."

Using a multifaceted approach in mice, we examined tracer dynamics and the CSF outflow pathway from the subarachnoid space (SAS) to the nasal mucosa and identified a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations. Similar arachnoid fenestrations were found in cynomolgus monkeys. Fluorescent tracers in the SAS passed through arachnoid fenestrations into dural lymphatics, which traversed the cribriform plate foramina, joined the nasal lymphatics, and drained to the cervical lymph nodes. In aged mice, the known reduction in CSF outflow was accompanied by lymphatic atrophy in the olfactory dura and nasal mucosa and by fewer arachnoid fenestrations and smaller cribriform plate foramina. Importantly, the lymphatics and CSF clearance were restored to normal by intranasal delivery of vascular endothelial growth factor-C (VEGF-C), thereby documenting the reversibility of the aging-related impairment in CSF clearance."

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations."

Despite this commonality, most current therapeutic approaches in the field, such as anti-aggregate antibodies, are focused on individual diseases or single neuropathologies with only limited success. The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases. Thus, these proteins are predicted to participate in common pathogenic pathways shared across various neurodegenerative diseases. Importantly, recent discoveries of TMEM106B amyloid fibrils in varied neurodegenerative diseases and glycosphingolipid regulation by progranulin and TMEM106B further support their central roles in cross-disease neurodegenerative mechanisms. This review summarizes recent advances in progranulin and TMEM106B function within the endolysosomal system and neurodegenerative diseases. It describes preclinical models and therapeutic approaches for progranulin- and TMEM106B-associated diseases. We also discuss future direction leading to novel alternative therapies targeting shared mechanisms in neurodegenerative diseases."

However, mutations in TMEM106B increase its expression level, thus the molecular process linking these mutations to the apparent disruption in TMEM106B function remains mysterious. Recent new studies reported that TMEM106B proteins form intracellular amyloid filaments which universally exist in various neurodegenerative diseases, sometimes being the dominant form of protein aggregation. In light of these new findings, in this review we systematically examined previous efforts in understanding the function of TMEM106B in physiological and pathological conditions. We propose that TMEM106B aggregations could recruit normal TMEM106B proteins and interfere with their function. TMEM106B mutations could lead to lysosome dysfunction by promoting the aggregation of TMEM106B and reducing these aggregations may restore lysosomal function, providing a potential therapeutic target for various neurodegenerative diseases."

The estrogen decline increases vulnerability to mood disorders, but the molecular mechanisms underlying stress resilience remain unclear. Here, we identify hippocampal neuronal progranulin (PGRN), a secreted neuroprotective glycoprotein, as a key regulator of affective resilience under estrogen-deficient conditions. Ovariectomy (OVX) reduces hippocampal neuronal PGRN expression and induces anxiety- and depression-like behaviors, whereas estradiol supplementation restores both PGRN levels and behavior. Adeno-associated virus (AAV)-mediated overexpression of PGRN alleviates affective deficits across OVX, 4\u2011vinylcyclohexene diepoxide (4-VCD)-induced ovarian failure, and natural aging models, while neuronal, but not microglial, Grn deletion exacerbates stress susceptibility.

Intracerebral recombinant PGRN rescues OVX\u2011induced behavioral deficits, and the blood-brain barrier (BBB)-permeable fragment granulin-E (GRN\u2011E) confers similar protection after systemic administration.

Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood.

Nasal administration has emerged as a promising non-invasive route, bypassing the BBB via direct neural pathways (olfactory/trigeminal), systemic absorption, or lymphatic drainage. However, inherent nasal barriers like the mucus layer and epithelium limit its efficacy. This review distinguishes itself by integrating mechanistic insights into nasal transport pathways with the rational design of advanced nano-delivery systems. We first outline the challenges in CNS drug delivery and detail the nasal anatomy and transport pathways facilitating nose-to-brain delivery. Subsequently, we emphasize the critical properties required of advanced nano-carriers to improve mucosal penetration, prolong retention, and promote drug accumulation at cerebral injury sites. Following a detailed analysis of the advantages and limitations associated with nose-to-brain delivery, we consolidate recent advances in nasal nano-delivery systems for treating CNS disorders, emphasizing their capacity to improve brain-targeting efficiency, enhance therapeutic efficacy, reduce systemic toxicity, and enable previously undruggable CNS targets. Finally, we expand the discussion to encompass current challenges impeding clinical translation, including safety concerns, manufacturing scalability, and regulatory hurdles, while highlighting emerging trends such as artificial intelligence-driven formulation design. This comprehensive analysis aims to deepen the understanding of nasal-to-brain transport mechanisms and inform the future development of effective nasal formulations for improved neurological therapeutics."

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity."

While cobalt ions are linked to neurodegenerative diseases, the neurodevelopmental toxicity of Co3O4 NPs remains poorly understood. Ferroptosis, a process regulated by iron homeostasis, can be triggered by ferrous overload through ferritinophagy. This study explores how Co3O4 NPs induce ferritinophagy and their role in neurodevelopmental toxicity. Zebrafish larvae exposed to Co3O4 NPs at concentrations of 0, 5, and 50\u202fmg/L for up to 120\u202fh post-fertilization (hpf) exhibited dose-dependent developmental toxicity, including delayed hatching, increased malformations, and impaired motor behavior. Transgenic zebrafish models demonstrated neuronal shortening, reduced fluorescence, and altered neurotransmitter profiles, as supported by liquid chromatography-tandem mass spectrometry. Co3O4 NPs induced oxidative stress, leading to iron overload, lipid peroxidation (elevated MDA, depleted glutathione), and ferritinophagy activation, as evidenced by changes in genes and proteins related to iron metabolism (trf, fpn, slc7a11) and ferroptosis (GPX4, ACSL4, FTH1, NCOA4). Ferritinophagy was further confirmed using autophagy inhibitors, demonstrating its role in neurotoxicity. Additionally, Vitamin E (d-\u03b1-tocopherol), a lipid-soluble antioxidant that suppresses lipid peroxidation, reduced neurodevelopmental abnormalities, supporting that Co3O4 NP-induced toxicity occurs through ferritinophagy-mediated ferroptosis, leading to neurotransmitter dysregulation. These findings were corroborated in human neuroblastoma cells (SH-SY5Y/SK-N-SH). In conclusion, Co3O4 NPs disrupt iron homeostasis, activate ferritinophagy, and induce ferroptosis, resulting in neurotransmitter dysregulation and neurodevelopmental toxicity. These results provide new insights for assessing the neurodevelopmental toxicity and environmental risk of Co3O4 NPs and similar nanomaterials."

A pivotal feature of PD pathogenesis is the dual role of microglia, which shifts from maintaining neuronal homeostasis to driving neuroinflammation and neurodegeneration. The mechanisms underlying this functional transition and its consequences for disease progression require a comprehensive synthesis. A structured PubMed search was performed using the keywords \"Parkinson's disease\", \"microglia\", \"neuroinflammation\", \"\u03b1-synuclein\", \"polarization\", \"tunneling nanotubes (TNTs)\", \"NF-\u03baB\", and \"NLRP3\". Relevant combinations of these terms were also used. A total of 2952 records were retrieved up to December 2025. Of these, 147 studies were included based on relevance to microglial polarization, neuroinflammation, \u03b1-syn-related pathology, and intercellular communication mechanisms. In early PD stages, microglia exert neuroprotective effects by transferring excess neuronal \u03b1-syn via TNTs, delivering healthy mitochondria, and clearing \u03b1-syn through autophagy. With disease progression, accumulated \u03b1-syn promotes microglial polarization toward the M1 phenotype. This shift activates TLR2/4, TREM2, MHCII, and RAGE receptors, triggering NF-\u03baB/NLRP3 pathways, releasing pro-inflammatory cytokines, and generating NOX2-derived ROS. The resulting neuroinflammatory cascade not only damages dopaminergic neurons directly but also disrupts astrocyte function and blood-brain barrier integrity, creating a self-perpetuating cycle of inflammation and neurodegeneration. These findings support dysregulated microglial polarization as an important component of PD pathobiology, but the available evidence remains weighted toward preclinical models. Future work should better define the timing, heterogeneity, and clinical measurability of microglial state transitions before microglia-targeted strategies can be translated with confidence. Microglial polarization may represent a potential therapeutic direction in Parkinson's disease, although further mechanistic and clinical validation and more precise biomarker definition remain necessary."

Dysregulation of these processes is implicated in numerous diseases, including cancer, liver disorders, and neurodegenerative diseases. p62/Sequestosome 1 (SQSTM1) is a multifunctional protein that plays a central role in protein homeostasis and stress responses by regulating autophagy and signal transduction pathways. Through its multiple protein-interacting domains, p62 functions both as a scaffold for selective autophagic degradation and as a signaling hub. Since our previous review of p62 a decade ago, substantial progress has been made in elucidating its molecular functions and physiological roles. Notably, p62 undergoes liquid-liquid phase separation with ubiquitinated proteins to form membraneless condensates, termed p62 bodies, when cells are exposed to proteotoxic stress. By sequestering specific proteins, p62 bodies act as platforms for autophagy-dependent degradation and stress signaling. These findings have substantially revised our view of p62 function, which was previously considered primarily as a receptor simply linking ubiquitinated substrates to autophagic membranes and connecting signaling molecules. This conceptual shift from one-to-one molecular interactions to multivalent, multimolecular, higher-order assemblies has fundamentally redefined the functional landscape of p62. In this review, we highlight how p62 bodies integrate selective autophagy and stress signaling, with a particular emphasis on their emerging roles in disease pathogenesis and their potential as therapeutic targets."

Although \u03b1-syn aggregation is considered central to PD pathogenesis, increasing evidence suggests that \u03b1-syn abundance may be as important as its conformational state. Genetic studies have demonstrated an SNCA dosage effect, with gene duplication and triplication associated with progressively more severe familial PD phenotypes. Complementary evidence indicates that dysfunction of protein clearance pathways, particularly the autophagy-lysosome system, promotes intracellular \u03b1-syn accumulation and increases its neurotoxic potential. In this review, we propose \u03b1-syn multiplication as an integrative framework for interpreting PD pathogenesis. This concept extends beyond SNCA copy-number variation to encompass processes that increase the effective \u03b1-syn burden within neurons or across neural networks, including increased gene expression, impaired degradation, disrupted proteostasis, and pathological propagation. We summarize \u03b1-syn structural dynamics and the concentration-dependent distribution of monomeric, oligomeric, and fibrillar species. We then review evidence from SNCA gene-dosage studies and examine the role of the autophagy-lysosome pathway in regulating \u03b1-syn homeostasis, with particular emphasis on recent experimental findings demonstrating that autophagy deficiency exacerbates \u03b1-syn accumulation and neurodegeneration in human \u03b1-syn bacterial artificial chromosome transgenic mice. Collectively, the available genetic, biochemical, and experimental evidence supports a model in which the balance between \u03b1-syn production and clearance influences disease progression alongside protein misfolding. The interaction between increased protein burden and impaired clearance capacity provides a unifying mechanism linking familial and sporadic forms of PD. We propose that \u03b1-syn multiplication offers an integrative framework for understanding PD pathogenesis, provides a quantitative perspective on disease heterogeneity, and highlights therapeutic opportunities aimed at reducing \u03b1-syn burden and restoring proteostatic balance."

Mitophagy, the selective degradation of damaged or superfluous mitochondria, plays a central role in maintaining mitochondrial integrity and metabolic balance. This review provides a comprehensive overview of the best-characterized PINK1-PRKN/parkin-dependent mitophagy pathway and the expanding repertoire of PRKN-independent mechanisms, including additional ubiquitin-dependent, receptor-mediated, and lipid-mediated pathways.

Mechanistically, tumor-derived exosomes efficiently deliver circAP2B1 to tumor-associated macrophages (TAMs), where it serves as a distinct molecular scaffold that simultaneously binds the transcription factor ESRRA and the nuclear import receptor KPNA1, facilitating ternary complex formation and ESRRA nuclear translocation. Once in the nucleus, ESRRA directly activates the transcription of Mitofusin 2 (MFN2), a pivotal regulator of mitochondrial fusion, thereby enhancing mitochondrial oxidative phosphorylation, improving ATP production efficiency, and establishing a metabolically optimized intracellular environment that ultimately drives TAMs toward a pro-tumor M2 phenotype. Both in vitro and in vivo experiments demonstrate that targeted intervention of the circAP2B1/ESRRA/KPNA1/MFN2 signaling axis effectively reverses M2 polarization and markedly suppresses tumor progression. This study uncovers a novel exosomal circRNA-mediated metabolic-immune regulatory pathway and offers new avenues for the diagnosis and treatment of ESCC. The findings not only expand the understanding of circRNA functions in tumor immunity but also provide a theoretical basis for the development of therapies targeting the metabolic-immune axis."

Cycloheximide (CHX) is a global cytosolic translation inhibitor we previously reported to rescue PMD preclinical models, although its toxicity precluded clinical development. To identify specific mediators underlying CHX treatment benefit in PMD, SOMAscan-based proteomics was performed in complex I deficient and genetic disease fibroblast cell line models grown in galactose. Thrombopoietin (THPO) and insulin-like growth factor binding protein 5 (IGFBP5) were the only two differentially regulated proteins, together with ERK/MAPK pathway dysregulation, identified upon CHX treatment in PMD versus healthy control cells. THPO inhibition by siRNA or pharmacologic approaches rescued stress-induced viability loss in patient fibroblasts having diverse PMD gene etiologies, and significantly improved mitochondrial stress, linear growth, and neuromuscular function in a classical ndufs2 -/- C. elegans model. IGFBP5 overexpression by lentiviral or mRNA approaches rescued cell viability across distinct PMD gene etiologies, as did IGF1 pharmacologic inhibition across both PMD mutant and C. elegans models. MAPK pharmacologic inhibition rescued multiple distinct complex I disease cells' survival, as well as mitochondrial stress in SLC25A46 -/- C. elegans . Combination therapies targeting multiple of these glucose signaling pathway proteins, together with glucose and N-acetylcysteine, yielded superior therapeutic benefit in complex I disease cell and C. elegans models. Additionally, single or combined pharmacologic inhibition of THPO or IGF1 significantly enhanced primary and metastatic osteosarcoma cell death. Collectively, targeted small molecule and genetic modulation of THPO, IGF1, or MAPK recapitulated the significant therapeutic benefit of CHX in PMD, while avoiding global translation inhibition. These novel PMD therapies likely confer benefit by attenuating MAPK-driven autophagy and potentially promoting noncanonical glucose uptake, improving cellular energy balance. Overall, these glucose signaling cellular pathway targets hold broad therapeutic promise for PMD patients, warranting further clinical research development."

In recent years, compounds belonging to the 4H-pyran chemical class have attracted significant attention due to their pronounced antioxidant, anti-inflammatory, and cytoprotective properties. These molecules exhibit structural versatility, enabling modulation of multiple molecular targets involved in neuronal survival, redox homeostasis, and mitochondrial function. This review provides a comprehensive analysis of the pharmacological activity and molecular mechanisms of action of five 4H-pyran-based compounds-maltol, kojic acid, chelidonic acid, comenic acid, and meconic acid. Special attention is paid to their effects on signaling pathways that play a central role in maintaining neuronal integrity and resistance to stress factors. In particular, the review examines how these compounds regulate key intracellular cascades such as nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1)/antioxidant response element (ARE), Nrf2/PTEN-induced putative kinase 1 (PINK1)/Parkin, nuclear factor-kappa B (NF-\u03baB), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR), which are critically involved in controlling oxidative stress, mitochondrial autophagy, inflammation, and neuronal plasticity. The integrated evaluation of these mechanisms demonstrates that 4H-pyran-based acids can act as multitarget neuroprotective agents capable of influencing both primary metabolic processes and secondary signaling responses to neurotoxic stimuli. Their pleiotropic action highlights the promise of these compounds as molecular scaffolds for the development of novel drugs aimed at preventing or delaying the progression of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases."

Metagenomic analysis revealed distinct microbial community structures, with increased abundance of Akkermansia massiliensis, Alistipes onderdonkii, and Barnesiella intestinihominis in AD. Phageome analysis revealed increased richness and altered composition, with more Podoviridae and fewer Microviridae. Functional profiling identified shifts in microbial metabolic pathways involving tryptophan and short-chain fatty acid metabolism. Untargeted metabolomics revealed elevated fecal spermidine, taurocholate, and glycerophosphocholine levels in patients with AD. A random forest model combining metabolites, gut metabolic modules, and bacteriophages achieved good within-cohort classification (AUC = 0.83) but lacked external validation due to unavailable matched fecal metabolomic data. Overall, these findings link AD to coordinated disruptions across bacterial, viral, and metabolic gut layers, highlighting the need for external validation and mechanistic studies."

Exosomes derived from adipose-derived mesenchymal stem cells (ADMSC-Exo) have robust protective effects under non-otologic ischemic conditions. However, their otoprotective effects remain unclear. This study aimed to investigate the protective effects of human ADMSC-Exo against cochlear damage and mitochondrial dysfunction under oxygen-glucose deprivation (OGD), an in vitro and ex vivo model of cochlear ischemia. ADMSC-Exo attenuated OGD-induced cytotoxicity and apoptosis in HEI-OC1 cells and reduced the OGD-induced loss of cochlear hair cells in the organ of Corti explants. OGD caused a decrease in mitochondrial mass and mitochondrial membrane potential depolarization and impaired mitochondrial respiration in auditory cells. ADMSC-Exo preserved mitochondrial integrity and improved mitochondrial bioenergetic function following OGD exposure. These effects were accompanied by increased LC3-II conversion and formation of autolysosome-like structures and elevated expression of PINK1 and Parkin, indicating the activation of autophagy and mitophagy-related protective mechanisms. Importantly, 3-methyladenine, an autophagy inhibitor, attenuated the cytoprotective effect of ADMSC-Exo, supporting the involvement of autophagy in ADMSC-Exo-mediated protection. Collectively, these findings suggest that ADMSC-Exo protect against OGD-induced cochlear injury by promoting autophagy-associated mitochondrial protection."

This research investigates the role of autophagy in renal damage caused by GoAstV in goslings. The findings indicated that GoAstV infection in goslings resulted in characteristic clinical manifestations, with renal tissues displaying tubular swelling, inflammatory infiltration, and autophagosome formation. In vivo experiments demonstrated a significant upregulation of mRNA levels for autophagy-related factors, including AMPK, LC3A, ATG5, ATG7, P62, Beclin1, AMBRA1 and GABARAPL1, while mTOR and LC3B levels were notably decreased. At 3 dpi, the protein expression levels of ATG5, Beclin1, and LC3B II/I increased, while P62 levels decreased, suggesting autophagy activation. In vitro analyses revealed that GoAstV infection led to enhanced autophagy; however, the concurrent upregulation of LC3B II/I and P62 proteins suggested an obstruction in the autophagic flux. Upon the inhibition of autophagy with 3-methyladenine (3-MA, autophagy inhibitor), there was a significant reduction in the expression of autophagy-related factors, accompanied by a marked decrease in viral replication rates. In conclusion, GoAstV infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux. The virus exploits autophagosomes for replication, ultimately resulting in kidney damage. The application of 3-MA effectively inhibits this autophagic process and diminishes viral replication."

Methods: We applied genomic structural equation modeling to European-ancestry GWAS summary statistics for five constituent phenotypes: depressive symptoms, depression diagnosis, grip strength, appendicular lean mass, and walking pace. A Depression-Physical Function shared genetic factor was constructed as a cross-trait genetic covariance dimension and evaluated using LDSC-based validation and leave-one-trait-out sensitivity analyses. We then performed factor GWAS, FUMA locus annotation, Bayesian fine-mapping, MAGMA gene-based analysis, transcriptome-wide association analysis, pathway enrichment, CELLECT/MAGMA cell-type specificity analysis, partitioned heritability analysis, and gsMap spatial transcriptomic mapping. Results: The shared factor showed good model fit and retained 755,397 quality-controlled variants for downstream analysis. The factor was positively genetically correlated with depression-related traits and negatively correlated with physical-function-related traits. FUMA identified 245 genome-wide significant SNPs, 44 lead SNPs, and 38 genomic risk loci, with 127 positional mapped genes. Fine-mapping prioritized one high-confidence locus. MAGMA identified 19 Bonferroni-significant genes and 326 FDR-significant genes, while TWAS identified 322 FDR-significant expression-associated genes. Integrating FUMA positional mapping, MAGMA gene-level association and TWAS expression-level association prioritized eight convergent genes: TMEM106B, CENPW, DRD2, LRFN5, NCAPG, DCAF16, SGIP1, and FAM120A. Functional enrichment highlighted postsynaptic structure, neuron spine, synaptic plasticity, and synapse organization. CELLECT/MAGMA prioritized brain non-myeloid neurons and glial populations, with additional endocrine-metabolic and immune-hematopoietic signals. Spatial transcriptomic mapping localized top signals to brain and spinal cord regions in the embryonic neuro-muscle reference. Partitioned heritability analysis showed enrichment in conserved, intronic, promoter, and chromatin-related genomic annotations. Conclusions: These findings support a shared polygenic covariance dimension linking depression-related liability with reduced physical-function-related genetic propensity. Downstream analyses prioritized candidate loci, genes, and biological contexts, with enrichment patterns consistent with neuronal, synaptic, and regulatory genomic processes."

Endoplasmic reticulum stress (ERS) and autophagy are implicated in its pathogenesis, but the precise mechanisms remain unclear. This study aimed to identify ERS and autophagy-related key genes (ERS-RGs and ARGs) in MCD using bioinformatic and experimental approaches. Methods: Transcriptomic data from GSE216841 and GSE246206 were analyzed. ERS-RGs and ARGs were obtained from prior literature. Candidate genes were selected by integrating weighted gene coexpression network analysis and differential expression analysis. Feature genes were identified via protein-protein interaction network analysis and machine learning (Least Absolute Shrinkage and Selection Operator and Boruta). Key genes were validated by expression analysis and receiver operating characteristic evaluation. A multilayer perceptron (MLP) model was constructed, and regulatory networks, immune infiltration, and chemical compound prediction were analyzed. The expression levels of the identified key genes were preliminarily assessed in peripheral blood samples using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Results:LIG4 and ZRANB3 were identified as key genes, both significantly downregulated in the MCD group, and the gene-based MLP model effectively predicted MCD probability. Overall, 13 significantly different immune cell types (e.g., CD56+ natural killer and activated dendritic cells) were detected. Regulatory networks (transcription factor-messenger RNA (mRNA) and long non-coding RNA-microRNA-mRNA) and 8 common chemical compounds (e.g., bisphenol A, acetaminophen) targeting these genes were predicted. Notably, peripheral blood RT-qPCR analysis revealed significant LIG4 and ZRANB3 downregulation, suggesting a systemic expression signature. Conclusions:LIG4 and ZRANB3 are key genes associated with ERS and autophagy in MCD, providing insights for diagnosis and targeted therapy."

Nose-to-brain (N2B) delivery has emerged as a non-invasive strategy to transport therapeutics to the central nervous system through the olfactory and trigeminal pathways, thereby partially bypassing the blood-brain barrier. Recent advances in nanomedicine and biomaterial engineering have further improved this approach by enhancing drug stability, nasal residence, mucosal transport, and brain-targeting efficiency. This review examines nanocarrier-enabled N2B delivery strategies for AD from a mechanism-guided perspective, highlighting how AD-related pathological processes shape the selection of therapeutic cargos and formulation designs. We discuss recent progress in the intranasal delivery of repurposed small molecules, natural products, insulin-related agents, peptides and proteins, extracellular vesicles, antibodies, and nucleic acid-based therapeutics. We further summarize major nanocarrier and formulation platforms, including lipid-based systems, polymeric nanoparticles, micelles, extracellular vesicles, in situ gels, and device-assisted delivery technologies. Particular attention is given to the design parameters that influence N2B performance, including particle size distribution/PDI, surface charge, mucus interaction, cargo protection, targeting modification, biodistribution, and deposition reproducibility. Finally, we critically evaluate the translational challenges that continue to limit clinical application, including species differences in nasal anatomy, dose-volume restrictions, device-dependent variability, limited human pharmacokinetic evidence, manufacturing complexity, long-term safety, and regulatory requirements. By integrating disease mechanisms, nanocarrier design, and translational considerations, this review provides a structured perspective for developing more rational and clinically feasible N2B nanodelivery systems for AD."

Recent studies have demonstrated that the gut microbiota acts as an important metabolic regulator and may play a pivotal role in the onset and progression of PCOS. Patients with PCOS frequently exhibit gut microbiota dysbiosis, which is characterized by reduced microbial diversity, decreased levels of beneficial bacteria, increased levels of pathogenic bacteria, and altered metabolic byproducts. This imbalance may contribute to IR and ovarian dysfunction by activating the toll-like receptor 4/nuclear factor kappa B inflammatory pathway, inducing oxidative stress, and disrupting Wnt/\u03b2-catenin signaling. The Wnt/\u03b2-catenin signaling pathway, a key regulator of follicular development, is frequently aberrantly activated in PCOS. In this narrative review, we summarize the recent advances in understanding the roles of the gut microbiota and the Wnt/\u03b2-catenin signaling pathway in the pathogenesis of PCOS. To this end, we conducted a comprehensive literature search across PubMed, Web of Science, Embase, and Cochrane Library databases, covering publications from January 2012 to March 2026. Ninety-eight articles were included after screening. We further explored therapeutic strategies based on microbiome modulation and signaling pathway targeting, including probiotics, traditional Chinese medicine, ginsenosides, puerarin, fecal microbiota transplantation, and nanoparticle-based ginseng-derived exosomes, thereby providing novel insights into potential therapies for PCOS."

Bone marrow mesenchymal stem cells-derived-exosomes (BMSCs-Exos) regulate osteoclast differentiation and osteoporosis in recent studies. But the mechanisms are still unclear. This research aimed to explore the mechanisms of BMSCs-Exos in osteoclast differentiation and osteoporosis. Exosomes were extracted from BMSCs. THP-1\u202fcells were cultured and treated with BMSCs-Exos. Osteoclast- and autophagy-related gene expression was assessed by qPCR and Western blot, the regulation of YAP1 by RBM15B was analyzed by MeRIP and RNA pull-down, osteoclast differentiation was detected by TRAP staining. HE staining, immunohistochemical staining and micro-CT were employed to assess the impact of BMSCs-Exos on osteoporosis. BMSCs-Exos were internalized by THP-1\u202fcells, promoted YAP1 expression and autophagy, and inhibited osteoclast differentiation. Silencing of YAP1 in THP-1\u202fcells reversed BMSCs-Exos-induced autophagy and the inhibition of osteoclast differentiation; conversely, YAP1 overexpression produced opposite effects. BMSCs-Exos-delivered RBM15B promoted m6A methylation modification of YAP1.

This study examined region-specific proteomic alterations in exosome-enriched small extracellular vesicles (exosome-enriched sEVs) from the cortex and hippocampus induced by neonatal propofol exposure. Using a clinically relevant repeated-dose regimen, C57BL/6 mice received propofol (50\u00a0\u00a0mg/kg, P5-P7). At P21, exosome-enriched sEVs were isolated and analyzed by data-independent acquisition mass spectrometry. Candidate differentially expressed proteins (candidate DEPs) were defined by fold change (FC)\u00a0\u2265\u00a01.5 or\u00a0\u2264\u00a00.667 and nominal p\u00a0<\u00a00.05, followed by Gene Ontology (GO), KEGG pathways, Cluster of Orthologous Groups (COG), and domain enrichment analyses. After Benjamini-Hochberg correction, no protein reached q\u00a0<\u00a00.05, indicating that the exploratory findings were not significant. We identified 63 candidate DEPs in the hippocampus and 55 in the cortex. Hippocampal downregulated proteins enriched in synaptic vesicle cycling, oxidative phosphorylation, and apoptosis, suggesting synaptic-mitochondrial disruption; upregulated proteins associated with ER stress and chaperone-mediated autophagy, suggesting proteostatic adaptation. Cortical candidate DEPs reflected suppressed mitochondrial function alongside enhanced translation and cytoskeletal remodeling. These region- and direction-specific changes were consistently observed across all bioinformatic platforms. The hippocampus showed pronounced synaptic and mitochondrial alterations, while the cortex exhibited cytoskeletal changes and metabolic shifts. In conclusion, Propofol induces distinct neurotoxic proteomic signatures in the neonatal hippocampus and cortex, suggesting compartment-specific vulnerability and compensatory remodeling. Thus, exosome-enriched sEV proteomics offers a sensitive approach to detecting early anesthetic-induced neurodevelopmental disturbances."

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

It has been used clinically to treat oligoasthenozoospermia (OAS) for more than two decades, with proven efficacy and a favorable safety profile. However, its precise molecular mechanism has yet to be fully elucidated. The aim was to investigate the therapeutic efficacy and the underlying mechanism of YSTLF in treating OAS associated with the kidney deficiency and collateral obstruction pattern. The chemical constituents of YSTLF were identified by UHPLC-Q-Orbitrap HRMS, and molecular docking was performed between the ten most abundant compounds and AMPK/mTOR. Rat OAS models were established by combined GTW, adrenaline, and ice-water immersion. Pharmacodynamic effects were evaluated through general status, reproductive organ weights, sperm quality, coagulation parameters, and serum sex hormones. Testicular histopathology, ultrastructure, and autolysosomes were examined by HE staining and TEM. Apoptosis was detected by TUNEL staining, and autophagy/apoptosis-related protein expression by IHC. Integrated metabolomics and proteomics with KEGG enrichment were conducted. In GTW-injured GC-1spg cells treated with Compound C or rapamycin, CCK-8 assay assessed viability, flow cytometry evaluated apoptosis, immunofluorescence examined LC3B/cleaved caspase-3 expression and colocalization, and Western blotting/RT-qPCR validated AMPK/mTOR pathway key molecules. Among 307 identified compounds (mostly flavonoids), YSTLF improved general status, organ weights, and sperm quality in model rats. The ten most abundant compounds showed binding energies < -7.0\u202fkcal/mol for AMPK/mTOR. Sperm concentration and motility increased dose-dependently. PT and TT were prolonged, FIB decreased, and FSH, LH, T, PRL, and Inh-B were restored. H&E, TEM, and TUNEL revealed alleviated testicular pathology, improved ultrastructure, reduced autolysosomes, and decreased apoptosis. IHC showed downregulated Beclin1 and Bax, and upregulated p62 and Bcl-2. Multi-omics revealed co-enrichment of differential proteins/metabolites in autophagy and mTOR pathways. Western blot/RT-qPCR validated downregulated p-AMPK/AMPK, AMPK mRNA, LC3II, Beclin1, Bax, cleaved caspase-3, and cleaved caspase-3/caspase-3 ratio, alongside upregulated p-mTOR/mTOR, mTOR mRNA, p62, and Bcl-2. In vitro, GTW reduced viability concentration-/time-dependently (stable model: 10%/24\u202fh); YSTLF reversed this (optimal: 15%/24\u202fh), restored viability, reduced apoptosis, and decreased LC3B/cleaved caspase-3 fluorescence/colocalization, while downregulating p-AMPK, LC3II, Bax and upregulating p-mTOR, p62, Bcl-2. Compound C alone mimicked YSTLF's effects without additivity, whereas rapamycin aggravated GTW-induced viability loss, apoptosis, and autophagy/apoptosis co-activation. YSTLF improved spermatogenic function in rats with OAS (kidney deficiency and collateral obstruction pattern). Its mechanism of action involves regulation of the AMPK/mTOR signaling pathway and restoration of the balance between autophagy and apoptosis."

Sixty male C57BL/6 mice were randomized into 5 groups (n=12), including a control group, a LPS-induced ALI model group, a Dex treatment group, and two BBP treatment groups treated with low- (30 mg/kg) or high-dose (120 mg/kg) BBP.

In LPS-stimulated RAW264.7 cells, BBP (12.5 \u03bcg/mL) significantly reduced the levels of TNF-\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, NO and ROS, enhanced SOD activity, increased mRNA expressions of I\u03baB-\u03b1, Nrf-2, and HO-1, and lowered mRNA expressions of TNF-\u03b1, IL-1\u03b2, Keap-1, and NF-\u03baB (p65). The ALI mouse models showed severe lung pathologies and edema, increased BALF cell counts, and increased levels of TNF\u2011\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, and NO, lowered SOD activity with reduced protein expressions of I\u03baB-\u03b1, Nrf-2, and HO-1 and increased expressions of Keap-1 and p65. Treatment with high-dose BBP significantly ameliorated lung pathologies in the mouse models and improved the aberrant alterations in pulmonary expressions of inflammatory factors, oxidative stress-related indicators and the NF-\u03baB and Nrf-2/HO-1 pathways. BBP protects against LPS-induced ALI in mice possibly by targeting the Nrf-2/HO-1 and NF-\u03baB pathways, suggesting its potential as a therapeutic agent for ALI. \u76ee\u7684: \u63a2\u7a76\u718a\u80c6\u7c89\uff08BBP\uff09\u901a\u8fc7\u8c03\u63a7NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u5bf9\u8102\u591a\u7cd6\u8bf1\u5bfc\u7684\u6025\u6027\u80ba\u635f\u4f24\uff08ALI\uff09\u5c0f\u9f20\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u4f53\u5916\u5b9e\u9a8c:\u91c7\u7528\u8102\u591a\u7cd6\uff08LPS\uff09\u8bf1\u5bfcRAW264.7\u7ec6\u80de\u5efa\u7acb\u4f53\u5916\u6a21\u578b\uff0c\u8bbe\u7f6e\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001\u5730\u585e\u7c73\u677e\uff08Dex\uff0c25 \u03bcg/mL\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff086.25 \u03bcg/mL\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff0812.5 \u03bcg/mL\uff09\u3002\u4f53\u5185\u5b9e\u9a8c:\u5c0660\u53eaC57BL/6\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001Dex\u7ec4\uff085 mg/kg\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff0830 mg/kg\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff08120 mg/kg\uff09\uff0c12\u53ea/\u7ec4\u3002\u901a\u8fc7ELISA\u548c\u76f8\u5173\u8bd5\u5242\u76d2\u68c0\u6d4b\u7ec6\u80de\u548c\u80ba\u7ec4\u7ec7\u4e2d\u708e\u75c7\u4e0e\u6c27\u5316\u5e94\u6fc0\u6307\u6807;\u901a\u8fc7\u80ba\u7ec4\u7ec7\u75c5\u7406\u5206\u6790\u3001\u514d\u75ab\u7ec6\u80de\u8ba1\u6570\u548c\u80ba\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u7b49\u6307\u6807\u8bc4\u4ef7BBP\u5bf9ALI\u7684\u5e72\u9884\u4f5c\u7528\u3002\u901a\u8fc7qRT-PCR\u3001Western blotting\u548c\u514d\u75ab\u7ec4\u5316\u6cd5\u5206\u6790NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u76f8\u5173\u86cb\u767d\u4e0e\u57fa\u56e0\u7684\u8868\u8fbe\u53d8\u5316\u3002\u7ed3\u679c: \u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\u7ec4\uff0812.5\u03bcg/mL\uff09\u663e\u8457\u964d\u4f4eTNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u4e00\u6c27\u5316\u6c2e\uff08NO\uff09\u548c\u6d3b\u6027\u6c27\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff0c\u4e14I\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff0c\u800cTNF-\u03b1\u3001IL-1\u03b2\u3001Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff08P<0.05\uff0cP<0.01\uff0cP<0.001\uff09\u3002\u52a8\u7269\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u7ed3\u6784\u7d0a\u4e71\uff0c\u80ba\u6ce1\u58c1\u589e\u539a\uff0c\u80ba\u6ce1\u5185\u53ef\u89c1\u5927\u91cf\u708e\u75c7\u7ec6\u80de\u6d78\u6da6\uff0c\u80ba\u7ec4\u7ec7\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u53ca\u652f\u6c14\u7ba1\u80ba\u6ce1\u704c\u6d17\u6db2\uff08BALF\uff09\u603b\u7ec6\u80de\u6570\u5347\u9ad8\uff08P<0.01\uff09;\u80ba\u7ec4\u7ec7\u4e2d\u7684TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u542b\u91cf\u5347\u9ad8\uff0c\u800cSOD\u6d53\u5ea6\u964d\u4f4e\uff08P<0.01\uff0cP<0.001\uff09;\u4e14\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff0cKeap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\uff08120 mg/kg\uff09\u7ec4\u80fd\u6539\u5584\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u75c5\u7406\u635f\u4f24\u72b6\u6001\uff0c\u6539\u5584\u80ba\u80bf\u80c0\u7a0b\u5ea6\uff0c\u964d\u4f4eBALF\u603b\u7ec6\u80de\u6570\u3001TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09;\u540c\u65f6\uff0cBBP\u4e0a\u8c03\u4e86\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u5e76\u6291\u5236\u4e86Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09\u3002\u7ed3\u8bba: BBP\u53ef\u80fd\u901a\u8fc7\u4f5c\u7528\u4e8eNrf-2/HO-1\u548cNF-\u03baB\u4fe1\u53f7\u901a\u8def\u5bf9LPS\u8bf1\u5bfc\u7684ALI\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u540e\u7eed\u7814\u7a76\u6f5c\u5728\u7684\u6cbb\u7597ALI\u836f\u7269\u63d0\u4f9b\u4f9d\u636e\u3002."

This study aimed to provide randomised comparative evidence on the efficacy and safety of thiotepa-based HCT-ASCT versus non-myeloablative R-DeVIC consolidation after uniform MATRix induction in newly diagnosed PCNSL. This open-label, randomised, phase 3 trial was conducted across 56 university and academic non-university hospitals with established transplantation facilities in five European countries. Eligible for inclusion were untreated, immunocompetent patients with B-cell PCNSL, aged 18-65 years regardless of Eastern Cooperative Oncology Group (ECOG) performance status, or 66-70 years with ECOG performance status 0-2. Pretreatment corticosteroids were permitted. Exclusion criteria included lymphoma manifestation outside the CNS, and congenital or acquired immunodeficiency. Patients received four cycles of MATRix induction (comprising rituximab, high-dose cytarabine, and thiotepa, in addition to high-dose methotrexate). Patients reaching at least partial response were randomly assigned (1:1) to two cycles of R-DeVIC (rituximab plus dexamethasone, etoposide, ifosfamide, and carboplatin) or HCT-ASCT with carmustine and thiotepa. The primary endpoint was progression-free survival, assessed in the full analysis set (excluding patients with major violations of entry criteria). The safety analysis set contained all randomised patients who initiated therapy. This study is registered with ClinicalTrials.gov (NCT02531841) and the EU Clinical Trials Register (EudraCT number 2012-000620-17). The study is completed. Between July 16, 2014, and Aug 31, 2019, 368 patients were enrolled. 346 (94%) patients started induction treatment, and 230 were randomly assigned; 229 patients were analysed (R-DeVIC group, n=115; HCT-ASCT group, n=114). After a median follow-up of 45\u00b73 months, 3-year progression-free survival was significantly superior in the HCT-ASCT group (hazard ratio 0\u00b743 [95% CI 0\u00b727-0\u00b768]; p=0\u00b70003). The 3-year progression-free survival was 78% (95% CI 69-85) in the HCT-ASCT group compared with 51% (41-60) in the R-DeVIC group. The mean number of adverse events per patient was 9\u00b73 (SD 4\u00b74) in the R-DeVIC group and 14\u00b76 (5\u00b78) in the HCT-ASCT group. Fatal serious adverse events following consolidation treatment occurred in two patients in the R-DeVIC group (both acute myeloid leukaemia) and in five patients in the HCT-ASCT group (infections and infestations [n=4], pulmonary embolism [n=1]); all of these events apart from the pulmonary embolism were judged to be possibly related to treatment. In the largest randomised trial in untreated PCNSL to date, HCT-ASCT significantly improved progression-free and overall survival compared with non-myeloablative consolidation in patients who had completed induction treatment, establishing it as the preferred consolidation strategy in fit patients.

"abstract_text": "ID: 42484065\nTitle: Global Phosphoproteome Analysis Identifies CLK4 Co-Regulatory Pathways Driving Tumor-Specific Dysregulation.\nAbstract: Dual-specificity protein kinase CLK4 plays a pivotal role in regulating alternative mRNA splicing, DNA repair, and various cellular processes through precise phosphorylation. In this study, we analyzed 3825 global human cellular phosphoproteome studies, identifying 430 qualitative profiles and 55 quantitative differential datasets featuring high-confidence Class-1 phosphosites (localization probability \u2265 75%; A-score \u2265 13). Notably, S136 and S138 emerged as predominant phosphorylation sites outside the kinase domain. These sites showed frequent detection and differential expression in liver, lung, and head and neck cancers, as documented in PhosphositePlus. We identified a high-confidence set of co-regulated phosphoproteins, including SQSTM1, SRRT, RPS6, TP53BP1, TNKS1BP1, THUMPD1, OTUD4, and TCEA1. These proteins link CLK4 to critical pathways, including RNA splicing, autophagy, DNA damage response, and cancer progression. Binary interactors, including SRRM2, Interacts with SPT6 1 (IWS1), RBBP6, ZC3H18, BUD13, and DYRK1A, further connect CLK4 to RNA processing and splicing. Predicted downstream substrates, such as CCNL2, CDK11B, PRDX6, YTHDC1, RBM15, SRRM1, SFSWAP, HNRNPU, and DOCK7, highlight CLK4's broad regulatory scope. Upstream kinases were also predicted for S136 and S138. Site-resolved analyses revealed tumor-specific dysregulation of CLK4 phosphorylation at key residues. Co-occurring phosphosite alterations and nearby somatic mutations suggest disrupted CLK4 regulation in cancer. Overall, this study provides a comprehensive phosphoproteomic resource that maps CLK4's co-regulatory networks, paving the way for mechanistic investigations and targeted cancer therapies."

A total of 36 male SD rats were randomly assigned to sham operation, model and acupoint pair groups, with 12 rats in each group. The IDD model was established by annulus fibrosus puncture. After modeling, rats of the acupoint pair group received acupuncture stimulation of bilateral SI3 and GB30, with the acupuncture needles retained for 20 min, once daily for 14 consecutive days. Before and after modeling and after the intervention, the mechanical withdrawal reflex threshold (mechanic pain threshold) of the right foot was measured using VonFrey filaments, and the thermal pain threshold measured by using a thermal pain tester. The morphological characteristics of the intervertebral disc tissue were observed by H.E. staining. The contents of type \u2161 collagen (Collagen \u2161), Aggrecan, matrix metalloproteinase 3 (MMP3), matrix metalloproteinase 13 (MMP13), and transcription factor sex-determining region Y-box protein 9 (SOX9) in the nucleus pulposus tissue were detected by ELISA. The mRNA relative expression levels of SOX9 and MMP13 in the nucleus pulposus tissue were detected by real-time fluorescence quantitative PCR. The positive expression of microtubule-associated protein 1 light chain 3 (LC3) in the nucleus pulposus tissue was detected by immunofluorescence staining. The expression levels of PI3K/AKT/mTOR signaling pathway-related proteins and LC3- \u2161, Beclin1, and chaperone 1 (p62) in the nucleus pulposus tissue were detected by Western blot. After modeling, in contrast to the sham operation group, the model group showed a striking decrease in the mechanical and thermal pain thresholds on day 7 and 14, contents of Aggrecan, collagen \u2161 and SOX9, and the expression levels of SOX9 mRNA and p62 protein, ratios of p-PI3K/PI3K, p-AKT/AKT, and p-mTOR/mTOR in the nucleus pulposus tissue (P<0.001, P<0.01), and a notable increase in the contents of MMP3 and MMP13, and MMP13 mRNA expression level, LC3 immunofluorescence intensity, and protein expressions of LC3-\u2161 and Beclin 1 (P<0.001). Under light microscope, the nucleus pulposus cells in the model group was relatively small in the number and discorded in the distribution, with a large number of vacuoles and chaotic matrix arrangement, and the lumbar intervertebral discs showed obvious degeneration, and decrease in the height. In comparison with the model group, both the decrease and increase of the indexes mentioned above were all reversed in the acupoint pair group (P<0.001, P<0.01, P<0.05). The results of H.E. stain displayed that in the acupoint pair group, the arrangement of the nucleus pulposus cells was more regular, and the number of vacuoles was reduced. Acupuncture of acupoint pair SI3 and GB30 can mitigate pain and regulate the autophagy process of lumbar intervertebral disc nucleus cells, reduce the degree of degradation of cytoplasmic matrix, and thereby delay the progression of IDD, which may be associated with its function in activating PI3K/AKT/mTOR signaling pathway in IDD rats. \u76ee\u7684:

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

Panasenoside (PSS) is a flavonoid glycoside ioslated from Chinese Materia Medica GINSENG RADIX ET RHIZOMA which has been demonstrated with multiple biological activities. However, the pharmacological activity of PSS and the underlying mechanism are still unclear. We found that PSS promoted sub-intestinal vessel plexus (SIVs) growth in zebrafish. PSS ameliorated vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor II (VRI)-induced deficiency of intersegmental vessels (ISVs) in a concentration dependent manner by downregulation of mRNA expression of VEGF receptors, including Kdr/VEGFR-2 (kdr), VEGFR-1 (flt1), and Kdr-like/VEGFR-2 (kdrl), and up-regulation of VEGF (vegfaa). The angiogenesis effect of PSS on VRI-induced ISVs deficiency was suppressed by PI3K, AKT, MEK, ERK, P38, Sirtuin 1 (SIRT1), Nuclear factor erythroid-2-related factor 2 (NRF2) and Nicotinamide N-methyl transferase (NNMT) inhibitors. Activation of NRF2, SIRT1 and MNA significantly restored VRI-induced ISVs insufficiency. In addition, PSS protected against VRI-induced tube formation deficiency in human umbilical vascular endothelial cells (HUVECs). SIRT1, NRF2 and NNMT inhibitors or siRNA eliminated PSS promoting vascular endothelial cell tube formation. PSS also prevented SIRT1, NRF2 and NNMT inhibitors-induced vascular endothelial cell senescence. Furthermore, PSS upregulated the protein expression level of SIRT1 and downregulated its downstreams P53 and PGC-1\u03b1 in HUVECs with high potence of activating SIRT1 by binding with its active domine. In conclusion, PSS presented pro-angiogenesis effect by mitigating vascular endothelial cell ageing and the underlying mechanisms were involved in the PI3K/AKT/MAPKs, SIRT1/NRF2 and NNMT/MNA signaling pathway with SIRT1 acting as a key regulator. We identified the pro-angiogenesis and anti-vascular endothelial cell ageing effects of PSS for the first time, and PSS is a promising drug candidate for treating vascular deficiency associated diseases."

In this study, we examined the effects of glucosamine (GlcN), a hexosamine biosynthetic pathway intermediate, on autophagy and lipid accumulation using both human hepatocellular carcinoma (HepG2) cells and a high-fat diet (HFD)-induced NAFLD mouse model. GlcN treatment led to a dose- and time-dependent increase in the expression of autophagy-related markers LC3 and p62 at both mRNA and protein levels. Pharmacological inhibition of O-GlcNAcase (OGA) further enhanced autophagic activity, whereas inhibition of O-GlcNAc transferase (OGT) abrogated GlcN-induced autophagic responses, implicating O-GlcNAcylation as a key mediator of GlcN-driven autophagy induction. Functionally, GlcN significantly reduced palmitic acid (PA)-induced lipid accumulation in HepG2 cells and alleviated hepatic steatosis in HFD-fed mice, likely through enhancement of autophagic flux. These findings demonstrate that GlcN promotes lipid clearance in hepatocytes via O-GlcNAc-dependent autophagy and highlight its potential as a therapeutic agent for NAFLD and related metabolic disorders."

MERLIN-SUITE (https://github.com/Roy-lab/MERLIN-SUITE) represents a collection of algorithmic extensions based on MERLIN (Modular regulatory network learning with per gene information) a probabilistic framework that infers gene-specific and module-specific regulatory programs of co-regulated modules, capturing both detailed and modular aspects of transcriptional networks. While expression-based inference is effective, it often aligns poorly with experimentally validated regulatory interactions. MERLIN-P addresses this by integrating external regulatory priors, such as motif, ChIP, and perturbation data, to enhance biological relevance and predictive accuracy. MERLIN-P-TFA further advances the framework by incorporating regularized estimation of latent transcription factor activity (TFA), overcoming the limitation that TF mRNA levels may not represent protein activity. By integrating expression data, prior knowledge, and activity-aware modeling, this unified approach supports robust GRN reconstruction in both bulk and single-cell datasets. This chapter presents the MERLIN-SUITE with a focus on MERLIN-P-TFA and demonstrates its use on a single-cell, multi-modal dataset of mouse cellular reprogramming to infer GRNs and identify key regulators."

"abstract_text": "ID: 42311424\nTitle: Engineering Nanocarriers for Dopamine Stabilization and Targeted Brain Delivery: Mechanisms, Approaches and Translational Challenges.\nAbstract: Dopamine plays a central role in motor control, cognition, reward signaling, and neuroendocrine regulation, and its dysregulation is strongly associated with neurological disorders such as Parkinson's disease. However, conventional dopaminergic therapies remain limited by poor blood-brain barrier (BBB) penetration, rapid systemic metabolism, short half-life, peripheral toxicity, and dopamine oxidation-induced neurotoxicity. Nanomedicine-based drug delivery systems have emerged as promising strategies to overcome these limitations by enhancing dopamine stability, improving BBB transport, enabling controlled release, and facilitating targeted delivery to dopaminergic brain regions. This review comprehensively summarizes current advances in dopamine-targeted nanotherapeutics, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, dendrimers, inorganic nanoparticles, exosomes, and biomimetic vesicles. Particular emphasis is placed on the dual role of nanocarriers in both facilitating dopamine delivery and protecting dopamine from oxidative degradation and reactive oxygen species-associated toxicity. Among currently investigated platforms, polymeric nanoparticles, lipid-based nanocarriers, and exosome-inspired vesicles appear particularly promising due to their ability to improve dopamine stability, facilitate controlled release, enhance BBB penetration, and enable targeted brain delivery. The review additionally discusses receptor-mediated targeting strategies, intranasal delivery approaches, translational barriers, manufacturing scalability, long-term safety considerations, and regulatory challenges associated with clinical implementation. Finally, emerging future directions involving AI-assisted nanocarrier engineering, precision-targeted delivery systems, and stimuli-responsive nanomedicine are highlighted as promising approaches for the development of next-generation therapies for neurodegenerative disorders."

This complexity makes it challenging to identify the key genes and the specific alleles that confer tolerance. We used time-course expression analysis to profile gene and miRNA expression associated with salt tolerance in Pokkali, a salt-tolerant rice variety. We established a framework for studying transcription factor-target(mRNA/miRNA) interactions using gene co-expression and machine-learning models. Moreover, we developed a hypergeometric distribution-based method to elucidate the interactions of salt stress-related miRNA-targets. Using these approaches, we established co-expression (GCN) and gene regulatory networks (GRN) based on co-expression and TF/miRNA-target interactions. Hub genes with high connectivity in our networks were enriched for previously reported salt tolerance genes, a finding largely supported by subsequent haplotype analysis of 374 rice accessions. Finally, we functionally validated three crucial hub genes, OsCAF1B, OsADR3 and Ospdr9, by demonstrating their roles in salt tolerance using their knockout mutants. The crucial genes, haplotypes and networks for salt tolerance identified in this study (resource available at https://cbi.njau.edu.cn/RiceSALTnet) provide a foundation for breeding rice cultivars with enhanced salt tolerance."

"abstract_text": "ID: 42300978\nTitle: Next-generation intranasal delivery nano-platforms for targeted brain therapy of Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder that poses a growing global health burden. Effective drug delivery to the brain is largely constrained by the selective nature of the blood-brain barrier (BBB), which limits therapeutic efficacy of conventional oral medications. Intranasal administration has emerged as a noninvasive and promising route for direct nose-to-brain transport, circumventing BBB restrictions. This review explores the potential of intranasal drug delivery as an alternative approach for targeted brain therapy in Alzheimer's disease. It comprehensively discusses the mechanisms of nasal absorption, physiological and formulation-related barriers, and the role of advanced nanocarrier platforms in overcoming these limitations. Emphasis is placed on recent innovations involving polymeric, lipid-based, and vesicular carriers, along with the incorporation of mucoadhesive and permeation-enhancing agents. The present focus is enhancing bioavailability, prolonging drug residence time, and minimizing systemic toxicity. Surface modifications of nanocarriers further facilitates mucosal adhesion and enables effective nose-to-brain transport of encapsulated therapeutic agents. However, clinical translation remains challenging due to interindividual variability in nasal physiology, scalability constraints, and regulatory complexities. Future progress will depend on the rational design of multifunctional nanocarriers, integration of mucoadhesive and stimuli-responsive components, and the use of precision-based formulation strategies."

To overcome these limitations, a Lactoferrin (Lf)-functionalized BXP-loaded nanostructured lipid carrier (Lf-BXP-NLC) incorporated into a thermoresponsive in situ nasal gel was developed to enable sustained and receptor-mediated nose-to-brain transport. The optimized formulation demonstrated nanoscale particle size (<200\u00a0nm), narrow polydispersity, high entrapment efficiency (\u223c88%), and physiological gelation temperature (30-34\u00a0\u00b0C), with preserved physicochemical stability over 3\u00a0months. In vitro release and ex vivo permeation studies confirmed controlled drug release and enhanced mucosal transport. In vivo pharmacokinetic evaluation in rats revealed significantly improved brain exposure following intranasal administration, with approximately 1.9-fold higher AUCbrain compared with drug suspension and 1.97-fold greater exposure relative to intravenous delivery. A rapid brain Tmax (0.41\u00a0h) and direct transport percentage of\u00a0\u223c\u00a062% indicated dominant neuronal pathway involvement and reduced reliance on systemic circulation. Enhanced pharmacokinetics translated into pronounced pharmacodynamic benefits in ketamine-induced schizophrenia models, including significant attenuation of stereotypic behaviors, restoration of motor coordination, and near-normalization of neuromuscular performance. Cross-species validation in zebrafish further demonstrated substantial correction of anxiety-like behavior and cognitive impairment, reinforcing translational robustness. Importantly, no nasal ciliotoxicity was observed. Collectively, this multifunctional intranasal nanocarrier platform achieves rapid, sustained, and targeted brain delivery of BXP and offers a promising non-invasive strategy for precision neuropsychiatric therapy."

Understanding these modules and how they evolve over time can be accomplished by constructing gene regulatory networks (GRNs). To identify context-specific TF subnetworks, we developed ChEA-KG, which generates enriched TF regulatory subnetworks for input gene sets. ChEA-KG is based on a GRN connecting 1559 human TFs via 131\u2009181 signed and directed edges inferred from diverse published ChIP-seq (chromatin immunoprecipitation followed by sequencing) and mRNA (messenger RNA)-sequencing experiments. We demonstrate ChEA-KG's utility by applying it to uncover master regulators of aging, mechanisms of action (MoA) for drug classes, pan-cancer subtypes, and cell types from across 14 major human tissues. Next, we extend ChEA-KG to develop the webserver application ChEA-KG Time Series (ChEA-KG-TS), which identifies TF modules from time-series mRNA-sequencing datasets. Results from this workflow are automatically summarized as reports that include enrichment analysis, regulatory subnetworks, and UMAP projections of enriched TFs. We use ChEA-KG-TS to explain transient responses in two use cases. ChEA-KG and ChEA-KG-TS are available from\u00a0https://chea-kg.maayanlab.cloud/ and https://chea-kg-ts.maayanlab.cloud/."

Meyer) is a classic herbal medicine widely utilized in dermatological management, yet its precise therapeutic mechanisms have only recently begun to be fully elucidated. This review systematically synthesizes the pharmacological roles of ginseng's active components, including ginsenosides, polysaccharides, and gintonin, in maintaining skin homeostasis and treating various cutaneous pathologies. Emerging evidence suggests that the efficacy of ginseng extends beyond direct molecular interactions, exhibiting the distinct characteristics of \"indirect pharmacology.\" Specifically, parent ginsenosides function primarily as natural prodrugs that require microbial biotransformation into high-affinity active metabolites, such as Compound K and Rh2, to exert potent therapeutic effects. Functionally, these components regulate skin health by mobilizing endogenous host defense systems, particularly through the activation of the Nrf2/ARE antioxidant pathway and the suppression of inflammatory cascades via the NF-\u03baB, MAPK, and IL-1 signaling networks. Furthermore, they remodel the systemic microenvironment through the gut-skin axis, facilitating metabolic homeostasis to improve skin barrier function. Notably, biotransformation rates and ultimate therapeutic efficacy are highly dependent on individualized variables, such as host age, dietary patterns, and baseline disease states. This systemic regulation has demonstrated robust efficacy in intervening in complex pathologies, including atopic dermatitis, psoriasis, and skin cancer. Additionally, this article addresses the translational bottleneck of low bioavailability and evaluates recent advances in novel skin delivery systems, specifically those utilizing ginseng-derived exosomes. Collectively, this review provides a scientific framework for understanding the systemic actions of ginseng, supporting its development as a precision botanical therapy for dermatological applications."

Panax notoginseng, a traditional medicinal herb, exhibits well-documented cardioprotective properties; however, the therapeutic application of its bioactive constituents is constrained by poor bioavailability and potential toxicity. Plant-derived extracellular vesicles (EVs) have emerged as natural nanocarriers facilitating cross-kingdom delivery of bioactive metabolites. In this study, we investigated whether P. notoginseng-derived EVs (PEVs) could mitigate Dox-induced cardiotoxicity (DIC) and explored the underlying mechanisms. PEVs were isolated from P. notoginseng rhizomes and systematically characterized, with metabolite profiling performed by UPLC-MS. Cellular uptake, biodistribution, and cardioprotective effects were evaluated in Dox-injured cardiomyocytes and a chronic mouse model of DIC. Mechanistic insights were obtained using transcriptomic analysis, molecular docking, and biochemical assays. PEVs were stable nanosized vesicles enriched with characteristic P. notoginseng metabolites, including triterpenoid saponins and dencichine. PEVs were efficiently internalized by cardiomyocytes and preferentially accumulated in injured myocardium. Functionally, PEVs attenuated Dox-induced inflammation, apoptosis, myocardial atrophy, fibrosis, and cardiac dysfunction, with efficacy comparable to dexrazoxane. Mechanistically, transcriptomic and molecular analysis identified p53 as a central regulatory target. PEVs-derived metabolites targeted the p53 DNA-binding domain, suppressing p53 phosphorylation and transcriptional activation of pro-apoptotic and inflammatory genes. Notably, p53 activation attenuated PEVs-mediated protection, whereas p53 inhibition or silencing abolished additional protective effects, indicating a p53-dependent mechanism. PEVs protect against DIC by delivering bioactive metabolites to injured myocardium and inhibiting p53-driven oxidative, inflammatory, and apoptotic pathways, highlighting their potential as a phytomedicine-based cardioprotective strategy."

Consequently, this route has been extensively investigated for treating diverse brain disorders, ranging from acute conditions to neurodegenerative diseases. Despite the advantages and clinical approval of several nasal products, the need for effective disease-modifying therapies (DMTs) of brain disorders remains unmet. Given that most brain disorders involve region-specific or cell-type-specific pathological changes, and that off-target effects may result in central nervous system toxicity, precision nose-to-brain delivery is critical. A major challenge to its clinical translation remains the lack of predictive, human-relevant preclinical models.

The blood-brain barrier (BBB), systemic toxicity, and first-pass metabolism are key obstacles. These factors limit the effective drug delivery to the brain. Intranasal administration has emerged as a noninvasive strategy to bypass the BBB. This approach enables direct drug delivery to the brain through the olfactory and trigeminal nerve pathways, commonly referred to as nose-to-brain (N2B) delivery. In this context, chitosan (CS), a biocompatible and mucoadhesive polysaccharide with permeation-enhancing properties, has gained significant interest as a functional material for nanoparticle (NP) engineering. CS-based or CS-coated NP can prolong the residence time on the nasal mucosa and facilitate drug transport to the CNS. This review provides a comprehensive overview of recent advances in CS-based NP for N2B drug delivery across a range of CNS disorders, including neurodegenerative, neuropsychiatric, neoplastic, and infectious conditions. Particular attention is given to formulation strategies, mechanistic insights, and preclinical outcomes.

Despite its therapeutic potential in neurodegenerative disorders, including Parkinson's disease, cerebral ischemia, and epilepsy, its clinical translation in Alzheimer's disease (AD) is hindered by poor aqueous solubility, limited systemic bioavailability, and restricted blood-brain barrier (BBB) permeability. This study aimed to overcome these limitations by formulating a BER-loaded nanoemulsion (BER-NE) for intranasal (IN) delivery to achieve direct nose-to-brain (N2B) targeting. The optimized NE exhibited a droplet size of 138.5\u00a0\u00b1\u00a00.96\u00a0nm and a polydispersity index (PDI) of 0.203\u00a0\u00b1\u00a00.007, indicating a monodisperse system. The BER-NE demonstrated a drug content of 99.62\u00a0\u00b1\u00a01.02%, confirming efficient drug incorporation. In vitro studies on SH-SY5Y neuroblastoma cells demonstrated that BER-NE reduced reactive oxygen species (ROS) levels by 2.09-fold and restored mitochondrial membrane potential (MMP) with a 3.61-fold increase in red/green fluorescence intensity compared to SCOP-induced cells. Further, pharmacokinetic (PK) profiling revealed that IN BER-NE achieved a 3.2- and 3.6-fold increase in brain Cmax compared to BER-SUS IN and BER-NE IV, respectively. The IN BER-NE demonstrated a 1.7- and 1.9-fold increase in %DTE and %DTP compared to the IN SUS, which supports the efficient N2B delivery. Behavioral assessments demonstrated dose-dependent reversal of SCOP-induced cognitive, depressive, and motor impairments. Additionally, treatment with HD BER-NE and MD BER-NE via the IN route markedly reduced the nitrite accumulation by 4.3- and 3.5-fold compared to the SCOP group, indicating attenuation of nitrosative stress. Collectively, these findings underscore the potential of IN BER-NE as a targeted and non-invasive therapeutic strategy for the management of AD."

This study aimed to investigate the mechanistic basis of NST using long noncoding RNA (lncRNA) and messenger RNA (mRNA) transcriptomics. The metabolites of NST were analyzed. Additionally, its systemically absorbed metabolites (in plasma) and brain-distributed metabolites were identified using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The therapeutic effects of NST were evaluated in a mouse model of middle cerebral artery occlusion (MCAO) using neurological scoring, behavioral testing, cerebral blood flow, and brain tissue staining. LncRNA and mRNA expression profiles were analyzed using the Agilent Mouse competing endogenous RNA microarray, followed by gene ontology and Kyoto encyclopedia of genes and genomes enrichment analyses. Differentially expressed transcripts were validated using quantitative reverse transcription polymerase chain reaction (qRT-PCR). UHPLC-MS/MS analysis detected 129 metabolites in NST; 33 metabolites in plasma; and 17 metabolites in brain tissue of rats administered with NST. NST treatment significantly reduced neurological deficit scores (Longa score), decreased beam-crossing latency, and increased forelimb grip strength in middle MCAO mice, indicating improved neurological function. Additionally, NST treatment enhanced cerebral blood flow recovery, ameliorated pathological damage, restored neuronal architecture, and increased Nissl-stained neuron density in peri-infarct brain tissue. NST also attenuated cellular apoptosis by upregulating Bcl-2 expression and downregulating Bax protein levels, exerting neuroprotective effects. Notably, NST treatment reversed 177 out of 5,378 differentially expressed IncRNAs and 52 out of 5,540 differentially expressed mRNAs that were dysregulated between the model and sham groups. These NST-modulated IncRNAs participate in key biological processes, including synaptic modulation, apoptosis regulation, and neuronal function. A synaptic plasticity-associated lncRNA-mRNA coexpression network was developed using NST-reversed transcripts. Validation using qRT-PCR confirmed the upregulation of NONMMUT050688.2 and NONMMUT044667.2, and the downregulation of NONMMUT092269.1 and NONMMUT101071.1, the downregulation of Nrn1, the upregulation of Grn, and the downward trend in Rasd2 expression in MCAO mice. All these alterations were reversed through NST treatment. In vivo experiments confirmed the efficacy of NST in ameliorating memory deficits, mitigating synaptic structural damage, and upregulating key synaptic protein expression (SYN and PSD95) in mice. NST may protect against cerebral ischemia/reperfusion injury by modulating lncRNA and mRNA expressions to enhance synaptic plasticity, thereby preserving neuronal structure and function."

These include receptor-mediated transcytosis, adsorptive-mediated transport, and intranasal delivery. NPs can also modify disease-related pathways. For example, they promote amyloid-\u03b2 clearance, reduce tau phosphorylation, and reprogram neuroimmune responses. Many preclinical studies have shown promising results in Alzheimer's, Parkinson's, and Huntington's diseases. However, no NP-based therapy has moved beyond early-stage clinical trials. Several issues remain unresolved. Direct comparisons between different NP platforms are lacking. The long-term toxicity of NPs in the brain is not well understood. Animal models also do not accurately reflect human disease. We suggest that future work should focus on standardized characterization, better predictive models, and clinical trial designs that address NP diversity. Researchers should also compare NP therapies with existing treatments in a rigorous manner."

In contrast, plant-derived exosomes (PDEs), as natural nanovesicles, offer significant advantages as drug delivery carriers due to their large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers.

The results demonstrated that G-CDDP effectively targeted tumor site, inhibiting the proliferation and migration and promoting apoptosis in U-87MG tumor cells. Notably, the amount of CDDP in G-CDDP required for achieving the same cytotoxic effect on tumor cells was 12.66 times lower than that of free CDDP. In U-87MG tumor-bearing mice, G-CDDP effectively targeted tumor sites and exhibited significant therapeutic effect.

Using a multifaceted approach in mice, we examined tracer dynamics and the CSF outflow pathway from the subarachnoid space (SAS) to the nasal mucosa and identified a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations. Similar arachnoid fenestrations were found in cynomolgus monkeys. Fluorescent tracers in the SAS passed through arachnoid fenestrations into dural lymphatics, which traversed the cribriform plate foramina, joined the nasal lymphatics, and drained to the cervical lymph nodes. In aged mice, the known reduction in CSF outflow was accompanied by lymphatic atrophy in the olfactory dura and nasal mucosa and by fewer arachnoid fenestrations and smaller cribriform plate foramina. Importantly, the lymphatics and CSF clearance were restored to normal by intranasal delivery of vascular endothelial growth factor-C (VEGF-C), thereby documenting the reversibility of the aging-related impairment in CSF clearance."

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations."

The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases.

Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations.

Nasal administration has emerged as a promising non-invasive route, bypassing the BBB via direct neural pathways (olfactory/trigeminal), systemic absorption, or lymphatic drainage. However, inherent nasal barriers like the mucus layer and epithelium limit its efficacy. This review distinguishes itself by integrating mechanistic insights into nasal transport pathways with the rational design of advanced nano-delivery systems. We first outline the challenges in CNS drug delivery and detail the nasal anatomy and transport pathways facilitating nose-to-brain delivery. Subsequently, we emphasize the critical properties required of advanced nano-carriers to improve mucosal penetration, prolong retention, and promote drug accumulation at cerebral injury sites. Following a detailed analysis of the advantages and limitations associated with nose-to-brain delivery, we consolidate recent advances in nasal nano-delivery systems for treating CNS disorders, emphasizing their capacity to improve brain-targeting efficiency, enhance therapeutic efficacy, reduce systemic toxicity, and enable previously undruggable CNS targets. Finally, we expand the discussion to encompass current challenges impeding clinical translation, including safety concerns, manufacturing scalability, and regulatory hurdles, while highlighting emerging trends such as artificial intelligence-driven formulation design.

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity."

While cobalt ions are linked to neurodegenerative diseases, the neurodevelopmental toxicity of Co3O4 NPs remains poorly understood. Ferroptosis, a process regulated by iron homeostasis, can be triggered by ferrous overload through ferritinophagy. This study explores how Co3O4 NPs induce ferritinophagy and their role in neurodevelopmental toxicity. Zebrafish larvae exposed to Co3O4 NPs at concentrations of 0, 5, and 50\u202fmg/L for up to 120\u202fh post-fertilization (hpf) exhibited dose-dependent developmental toxicity, including delayed hatching, increased malformations, and impaired motor behavior. Transgenic zebrafish models demonstrated neuronal shortening, reduced fluorescence, and altered neurotransmitter profiles, as supported by liquid chromatography-tandem mass spectrometry. Co3O4 NPs induced oxidative stress, leading to iron overload, lipid peroxidation (elevated MDA, depleted glutathione), and ferritinophagy activation, as evidenced by changes in genes and proteins related to iron metabolism (trf, fpn, slc7a11) and ferroptosis (GPX4, ACSL4, FTH1, NCOA4). Ferritinophagy was further confirmed using autophagy inhibitors, demonstrating its role in neurotoxicity. Additionally, Vitamin E (d-\u03b1-tocopherol), a lipid-soluble antioxidant that suppresses lipid peroxidation, reduced neurodevelopmental abnormalities, supporting that Co3O4 NP-induced toxicity occurs through ferritinophagy-mediated ferroptosis, leading to neurotransmitter dysregulation. These findings were corroborated in human neuroblastoma cells (SH-SY5Y/SK-N-SH). In conclusion, Co3O4 NPs disrupt iron homeostasis, activate ferritinophagy, and induce ferroptosis, resulting in neurotransmitter dysregulation and neurodevelopmental toxicity. These results provide new insights for assessing the neurodevelopmental toxicity and environmental risk of Co3O4 NPs and similar nanomaterials."

"abstract_text": "ID: 42576524\nTitle: The Double-Edged Sword: A Structured Narrative Review of Microglial Phenotypic Transition as a Pivotal Driver and Therapeutic Target in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder primarily involving the loss of dopaminergic neurons and pathological \u03b1-synuclein (\u03b1-syn) aggregation. A pivotal feature of PD pathogenesis is the dual role of microglia, which shifts from maintaining neuronal homeostasis to driving neuroinflammation and neurodegeneration. The mechanisms underlying this functional transition and its consequences for disease progression require a comprehensive synthesis. A structured PubMed search was performed using the keywords \"Parkinson's disease\", \"microglia\", \"neuroinflammation\", \"\u03b1-synuclein\", \"polarization\", \"tunneling nanotubes (TNTs)\", \"NF-\u03baB\", and \"NLRP3\". Relevant combinations of these terms were also used. A total of 2952 records were retrieved up to December 2025. Of these, 147 studies were included based on relevance to microglial polarization, neuroinflammation, \u03b1-syn-related pathology, and intercellular communication mechanisms. In early PD stages, microglia exert neuroprotective effects by transferring excess neuronal \u03b1-syn via TNTs, delivering healthy mitochondria, and clearing \u03b1-syn through autophagy. With disease progression, accumulated \u03b1-syn promotes microglial polarization toward the M1 phenotype. This shift activates TLR2/4, TREM2, MHCII, and RAGE receptors, triggering NF-\u03baB/NLRP3 pathways, releasing pro-inflammatory cytokines, and generating NOX2-derived ROS. The resulting neuroinflammatory cascade not only damages dopaminergic neurons directly but also disrupts astrocyte function and blood-brain barrier integrity, creating a self-perpetuating cycle of inflammation and neurodegeneration. These findings support dysregulated microglial polarization as an important component of PD pathobiology, but the available evidence remains weighted toward preclinical models. Future work should better define the timing, heterogeneity, and clinical measurability of microglial state transitions before microglia-targeted strategies can be translated with confidence. Microglial polarization may represent a potential therapeutic direction in Parkinson's disease, although further mechanistic and clinical validation and more precise biomarker definition remain necessary."

Dysregulation of these processes is implicated in numerous diseases, including cancer, liver disorders, and neurodegenerative diseases. p62/Sequestosome 1 (SQSTM1) is a multifunctional protein that plays a central role in protein homeostasis and stress responses by regulating autophagy and signal transduction pathways. Through its multiple protein-interacting domains, p62 functions both as a scaffold for selective autophagic degradation and as a signaling hub. Since our previous review of p62 a decade ago, substantial progress has been made in elucidating its molecular functions and physiological roles. Notably, p62 undergoes liquid-liquid phase separation with ubiquitinated proteins to form membraneless condensates, termed p62 bodies, when cells are exposed to proteotoxic stress. By sequestering specific proteins, p62 bodies act as platforms for autophagy-dependent degradation and stress signaling. These findings have substantially revised our view of p62 function, which was previously considered primarily as a receptor simply linking ubiquitinated substrates to autophagic membranes and connecting signaling molecules. This conceptual shift from one-to-one molecular interactions to multivalent, multimolecular, higher-order assemblies has fundamentally redefined the functional landscape of p62. In this review, we highlight how p62 bodies integrate selective autophagy and stress signaling, with a particular emphasis on their emerging roles in disease pathogenesis and their potential as therapeutic targets."

Although \u03b1-syn aggregation is considered central to PD pathogenesis, increasing evidence suggests that \u03b1-syn abundance may be as important as its conformational state. Genetic studies have demonstrated an SNCA dosage effect, with gene duplication and triplication associated with progressively more severe familial PD phenotypes. Complementary evidence indicates that dysfunction of protein clearance pathways, particularly the autophagy-lysosome system, promotes intracellular \u03b1-syn accumulation and increases its neurotoxic potential. In this review, we propose \u03b1-syn multiplication as an integrative framework for interpreting PD pathogenesis. This concept extends beyond SNCA copy-number variation to encompass processes that increase the effective \u03b1-syn burden within neurons or across neural networks, including increased gene expression, impaired degradation, disrupted proteostasis, and pathological propagation. We summarize \u03b1-syn structural dynamics and the concentration-dependent distribution of monomeric, oligomeric, and fibrillar species. We then review evidence from SNCA gene-dosage studies and examine the role of the autophagy-lysosome pathway in regulating \u03b1-syn homeostasis, with particular emphasis on recent experimental findings demonstrating that autophagy deficiency exacerbates \u03b1-syn accumulation and neurodegeneration in human \u03b1-syn bacterial artificial chromosome transgenic mice. Collectively, the available genetic, biochemical, and experimental evidence supports a model in which the balance between \u03b1-syn production and clearance influences disease progression alongside protein misfolding. The interaction between increased protein burden and impaired clearance capacity provides a unifying mechanism linking familial and sporadic forms of PD. We propose that \u03b1-syn multiplication offers an integrative framework for understanding PD pathogenesis, provides a quantitative perspective on disease heterogeneity, and highlights therapeutic opportunities aimed at reducing \u03b1-syn burden and restoring proteostatic balance."

In this study, circular RNA circAP2B1 is identified as a critical regulatory molecule that is markedly upregulated in ESCC tissues and patient serum and strongly associated with poor prognosis. Mechanistically, tumor-derived exosomes efficiently deliver circAP2B1 to tumor-associated macrophages (TAMs), where it serves as a distinct molecular scaffold that simultaneously binds the transcription factor ESRRA and the nuclear import receptor KPNA1, facilitating ternary complex formation and ESRRA nuclear translocation. Once in the nucleus, ESRRA directly activates the transcription of Mitofusin 2 (MFN2), a pivotal regulator of mitochondrial fusion, thereby enhancing mitochondrial oxidative phosphorylation, improving ATP production efficiency, and establishing a metabolically optimized intracellular environment that ultimately drives TAMs toward a pro-tumor M2 phenotype. Both in vitro and in vivo experiments demonstrate that targeted intervention of the circAP2B1/ESRRA/KPNA1/MFN2 signaling axis effectively reverses M2 polarization and markedly suppresses tumor progression. This study uncovers a novel exosomal circRNA-mediated metabolic-immune regulatory pathway and offers new avenues for the diagnosis and treatment of ESCC. The findings not only expand the understanding of circRNA functions in tumor immunity but also provide a theoretical basis for the development of therapies targeting the metabolic-immune axis."

Exosomes derived from adipose-derived mesenchymal stem cells (ADMSC-Exo) have robust protective effects under non-otologic ischemic conditions. However, their otoprotective effects remain unclear. This study aimed to investigate the protective effects of human ADMSC-Exo against cochlear damage and mitochondrial dysfunction under oxygen-glucose deprivation (OGD), an in vitro and ex vivo model of cochlear ischemia. ADMSC-Exo attenuated OGD-induced cytotoxicity and apoptosis in HEI-OC1 cells and reduced the OGD-induced loss of cochlear hair cells in the organ of Corti explants. OGD caused a decrease in mitochondrial mass and mitochondrial membrane potential depolarization and impaired mitochondrial respiration in auditory cells. ADMSC-Exo preserved mitochondrial integrity and improved mitochondrial bioenergetic function following OGD exposure. These effects were accompanied by increased LC3-II conversion and formation of autolysosome-like structures and elevated expression of PINK1 and Parkin, indicating the activation of autophagy and mitophagy-related protective mechanisms. Importantly, 3-methyladenine, an autophagy inhibitor, attenuated the cytoprotective effect of ADMSC-Exo, supporting the involvement of autophagy in ADMSC-Exo-mediated protection. Collectively, these findings suggest that ADMSC-Exo protect against OGD-induced cochlear injury by promoting autophagy-associated mitochondrial protection."

Recent studies have demonstrated that the gut microbiota acts as an important metabolic regulator and may play a pivotal role in the onset and progression of PCOS. Patients with PCOS frequently exhibit gut microbiota dysbiosis, which is characterized by reduced microbial diversity, decreased levels of beneficial bacteria, increased levels of pathogenic bacteria, and altered metabolic byproducts. This imbalance may contribute to IR and ovarian dysfunction by activating the toll-like receptor 4/nuclear factor kappa B inflammatory pathway, inducing oxidative stress, and disrupting Wnt/\u03b2-catenin signaling. The Wnt/\u03b2-catenin signaling pathway, a key regulator of follicular development, is frequently aberrantly activated in PCOS. In this narrative review, we summarize the recent advances in understanding the roles of the gut microbiota and the Wnt/\u03b2-catenin signaling pathway in the pathogenesis of PCOS. To this end, we conducted a comprehensive literature search across PubMed, Web of Science, Embase, and Cochrane Library databases, covering publications from January 2012 to March 2026. Ninety-eight articles were included after screening. We further explored therapeutic strategies based on microbiome modulation and signaling pathway targeting, including probiotics, traditional Chinese medicine, ginsenosides, puerarin, fecal microbiota transplantation, and nanoparticle-based ginseng-derived exosomes, thereby providing novel insights into potential therapies for PCOS."

Bone marrow mesenchymal stem cells-derived-exosomes (BMSCs-Exos) regulate osteoclast differentiation and osteoporosis in recent studies. But the mechanisms are still unclear. This research aimed to explore the mechanisms of BMSCs-Exos in osteoclast differentiation and osteoporosis. Exosomes were extracted from BMSCs. THP-1\u202fcells were cultured and treated with BMSCs-Exos. Osteoclast- and autophagy-related gene expression was assessed by qPCR and Western blot, the regulation of YAP1 by RBM15B was analyzed by MeRIP and RNA pull-down, osteoclast differentiation was detected by TRAP staining. HE staining, immunohistochemical staining and micro-CT were employed to assess the impact of BMSCs-Exos on osteoporosis. BMSCs-Exos were internalized by THP-1\u202fcells, promoted YAP1 expression and autophagy, and inhibited osteoclast differentiation. Silencing of YAP1 in THP-1\u202fcells reversed BMSCs-Exos-induced autophagy and the inhibition of osteoclast differentiation; conversely, YAP1 overexpression produced opposite effects. BMSCs-Exos-delivered RBM15B promoted m6A methylation modification of YAP1. Silencing of RBM15B in BMSCs blocked the impact of BMSCs-Exos on autophagy and osteoclast differentiation, whereas RBM15B overexpression exerted opposing influences. Furthermore, BMSCs-Exos suppressed osteoclast differentiation and alleviated osteoporosis in vivo through RBM15B/YAP1 mediated autophagy. BMSCs-Exos promoted m6A methylation modification of YAP1 by delivering RBM15B mRNA to enhance YAP1 RNA stability, promoted autophagy, and inhibited osteoclast differentiation and alleviated osteoporosis."

This study examined region-specific proteomic alterations in exosome-enriched small extracellular vesicles (exosome-enriched sEVs) from the cortex and hippocampus induced by neonatal propofol exposure. Using a clinically relevant repeated-dose regimen, C57BL/6 mice received propofol (50\u00a0\u00a0mg/kg, P5-P7). At P21, exosome-enriched sEVs were isolated and analyzed by data-independent acquisition mass spectrometry. Candidate differentially expressed proteins (candidate DEPs) were defined by fold change (FC)\u00a0\u2265\u00a01.5 or\u00a0\u2264\u00a00.667 and nominal p\u00a0<\u00a00.05, followed by Gene Ontology (GO), KEGG pathways, Cluster of Orthologous Groups (COG), and domain enrichment analyses. After Benjamini-Hochberg correction, no protein reached q\u00a0<\u00a00.05, indicating that the exploratory findings were not significant. We identified 63 candidate DEPs in the hippocampus and 55 in the cortex. Hippocampal downregulated proteins enriched in synaptic vesicle cycling, oxidative phosphorylation, and apoptosis, suggesting synaptic-mitochondrial disruption; upregulated proteins associated with ER stress and chaperone-mediated autophagy, suggesting proteostatic adaptation. Cortical candidate DEPs reflected suppressed mitochondrial function alongside enhanced translation and cytoskeletal remodeling. These region- and direction-specific changes were consistently observed across all bioinformatic platforms. The hippocampus showed pronounced synaptic and mitochondrial alterations, while the cortex exhibited cytoskeletal changes and metabolic shifts. In conclusion, Propofol induces distinct neurotoxic proteomic signatures in the neonatal hippocampus and cortex, suggesting compartment-specific vulnerability and compensatory remodeling. Thus, exosome-enriched sEV proteomics offers a sensitive approach to detecting early anesthetic-induced neurodevelopmental disturbances."

These sites showed frequent detection and differential expression in liver, lung, and head and neck cancers, as documented in PhosphositePlus. We identified a high-confidence set of co-regulated phosphoproteins, including SQSTM1, SRRT, RPS6, TP53BP1, TNKS1BP1, THUMPD1, OTUD4, and TCEA1. These proteins link CLK4 to critical pathways, including RNA splicing, autophagy, DNA damage response, and cancer progression. Binary interactors, including SRRM2, Interacts with SPT6 1 (IWS1), RBBP6, ZC3H18, BUD13, and DYRK1A, further connect CLK4 to RNA processing and splicing.

Intranasal administration has emerged as a noninvasive and promising route for direct nose-to-brain transport, circumventing BBB restrictions. This review explores the potential of intranasal drug delivery as an alternative approach for targeted brain therapy in Alzheimer's disease. It comprehensively discusses the mechanisms of nasal absorption, physiological and formulation-related barriers, and the role of advanced nanocarrier platforms in overcoming these limitations. Emphasis is placed on recent innovations involving polymeric, lipid-based, and vesicular carriers, along with the incorporation of mucoadhesive and permeation-enhancing agents. The present focus is enhancing bioavailability, prolonging drug residence time, and minimizing systemic toxicity. Surface modifications of nanocarriers further facilitates mucosal adhesion and enables effective nose-to-brain transport of encapsulated therapeutic agents. However, clinical translation remains challenging due to interindividual variability in nasal physiology, scalability constraints, and regulatory complexities.

Microglial dysfunction has been implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Impaired lysosomal function, particularly defective lysosomal acidification, leads to the accumulation of undegraded material, thereby promoting neuroinflammation and neuronal damage. This review examines the mechanisms governing lysosomal acidification in microglia and evaluates its potential as both a therapeutic target and a prognostic biomarker in neurodegenerative diseases. The literature on microglial lysosomal acidification, lysosomal pH regulation, autophagy, and neurodegeneration was searched in PubMed, Scopus, and Web of Science. Relevant mechanistic, preclinical, and translational studies were critically appraised and synthesized. Lysosomal acidification is increasingly recognized as a key regulator of microglial function and homeostasis. Defective acidification, driven by dysregulation of the vacuolar H+-ATPase (V-ATPase) proton pump, TFEB/TFE3 signaling pathways, and lysosomal ion channels such as TRPML1 and TMEM175, impairs autophagic flux and substrate degradation, facilitating the accumulation of neurotoxic aggregates including amyloid-\u03b2 and \u03b1-synuclein. Emerging evidence suggests that the degree of microglial lysosomal acidification may serve as a prognostic biomarker for disease progression and therapeutic response. Restoration or enhancement of lysosomal acidification through pharmacological modulation of lysosomal pH, activation of autophagy, or targeting of key regulatory pathways has been shown to re-establish microglial homeostasis, attenuate neuroinflammation, and confer neuroprotection in preclinical models. Restoration of microglial lysosomal acidification represents a promising therapeutic strategy for neurodegenerative diseases. A deeper understanding of the molecular mechanisms regulating lysosomal acidification in microglia may facilitate the identification of novel biomarkers and therapeutic targets, ultimately contributing to the development of innovative interventions for neurodegenerative disorders."

This research investigates the role of autophagy in renal damage caused by GoAstV in goslings. The findings indicated that GoAstV infection in goslings resulted in characteristic clinical manifestations, with renal tissues displaying tubular swelling, inflammatory infiltration, and autophagosome formation. In vivo experiments demonstrated a significant upregulation of mRNA levels for autophagy-related factors, including AMPK, LC3A, ATG5, ATG7, P62, Beclin1, AMBRA1 and GABARAPL1, while mTOR and LC3B levels were notably decreased. At 3 dpi, the protein expression levels of ATG5, Beclin1, and LC3B II/I increased, while P62 levels decreased, suggesting autophagy activation. In vitro analyses revealed that GoAstV infection led to enhanced autophagy; however, the concurrent upregulation of LC3B II/I and P62 proteins suggested an obstruction in the autophagic flux. Upon the inhibition of autophagy with 3-methyladenine (3-MA, autophagy inhibitor), there was a significant reduction in the expression of autophagy-related factors, accompanied by a marked decrease in viral replication rates. In conclusion, GoAstV infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux. The virus exploits autophagosomes for replication, ultimately resulting in kidney damage. The application of 3-MA effectively inhibits this autophagic process and diminishes viral replication."

Circular RNAs (circRNAs), characterized by their covalently bonded single-stranded loop configuration, have been identified as functional regulators across various cancer types. Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression."

MicroRNAs (miRNAs), which are critical post-transcriptional regulators, have emerged as important modulators of animal behavior. This study investigated the molecular basis of aggression in pigs ( Sus scrofa), focusing on miRNA-mediated regulation. Hypothalamic miRNA-sequencing of the most aggressive ( n=4) and least aggressive ( n=4) piglets identified nine differentially expressed miRNAs. Among these, miR-27a was significantly upregulated in aggressive individuals. Functional assays demonstrated that both porcine miR-27a and its human ( Homo sapiens) ortholog has-miR-27a-3p, suppressed autophagy, apoptosis, and neuronal plasticity in primary porcine neurons and human SH-SY5Y neuroblastoma cells. To clarify the underlying mechanisms, mRNA-sequencing was performed on porcine neurons transfected with miR-27a mimics or negative controls, identifying 436 differentially expressed genes (84 upregulated and 352 downregulated). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses highlighted eight genes- CBL, PRKCA, SLC38A1, ZBTB16, AANAT, CYP1A1, SLC7A11, and NTRK2-associated with tryptophan metabolism, oxidative stress, and long-term synaptic depression. Bioinformatic analysis and dual-luciferase reporter assays confirmed that miR-27a directly targets the 3'-UTR of PRKCA, thereby suppressing of autophagy, apoptosis, and neuronal plasticity. In vivo, intrahypothalamic injection of mmu-miR-27a-3p in mice ( Mus musculus) reduced motor function and social dominance, and placed the mice at a competitive disadvantage, while supressing neuronal autophagy, apoptosis and plasticity. \u968f\u7740\u96c6\u7ea6\u5316\u52a8\u7269\u751f\u4ea7\u7684\u666e\u53ca\uff0c\u4eba\u4eec\u5bf9\u52a8\u7269\u798f\u5229\u7684\u5173\u6ce8\u65e5\u76ca\u589e\u52a0\u3002\u653b\u51fb\u884c\u4e3a\u4f5c\u4e3a\u5f71\u54cd\u52a8\u7269\u798f\u5229\u7684\u91cd\u8981\u56e0\u7d20\uff0c\u5bf9\u63d0\u5347\u798f\u5229\u6c34\u5e73\u548c\u751f\u4ea7\u6548\u7387\u81f3\u5173\u91cd\u8981\u3002\u800c\u4f5c\u4e3a\u8f6c\u5f55\u540e\u8c03\u63a7\u7684\u5173\u952e\u5206\u5b50miRNA\u5df2\u6210\u4e3a\u52a8\u7269\u884c\u4e3a\u7684\u91cd\u8981\u8c03\u8282\u56e0\u5b50\u3002\u8be5\u7814\u7a76\u65e8\u5728\u4ece\u5206\u5b50\u5c42\u9762\u89e3\u6790\u732a\u653b\u51fb\u884c\u4e3a\u7684\u5f62\u6210\u673a\u5236\uff0c\u91cd\u70b9\u5173\u6ce8 miRNA \u4ecb\u5bfc\u7684\u8c03\u63a7\u4f5c\u7528\u3002\u901a\u8fc7\u5bf9\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\uff08 n = 4\uff09\u548c\u8f83\u5f31\uff08 n = 4\uff09\u4ed4\u732a\u4e0b\u4e18\u8111\u8fdb\u884c miRNA \u6d4b\u5e8f\uff0c\u5171\u9274\u5b9a\u51fa 9 \u79cd\u5dee\u5f02\u8868\u8fbe\u7684 miRNA\u3002\u5176\u4e2d\uff0cmiR-27a \u5728\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\u7684\u4e2a\u4f53\u4e2d\u663e\u8457\u4e0a\u8c03\u3002\u7ec6\u80de\u529f\u80fd\u5b66\u9a8c\u8bc1\u8868\u660e\uff0cssc-miR-27a \u53ca\u5176hsa-miR-27a-3p \u80fd\u591f\u6291\u5236\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u548c\u4eba\u795e\u7ecf\u6bcd\u7ec6\u80de\u7624\u7ec6\u80de\u7cfb\uff08SH-SY5Y\uff09 \u7684\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002\u4e3a\u4e86\u8fdb\u4e00\u6b65\u63a2\u7a76 miR-27a \u5bf9\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u7684\u8c03\u63a7\u4f5c\u7528\uff0c\u901a\u8fc7\u5bf9\u8f6c\u67d3 miR-27a \u6a21\u62df\u7269\u548c\u9634\u6027\u5bf9\u7167\u7684\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u8fdb\u884c mRNA-seq\uff0c\u5171\u9274\u5b9a\u51fa 436 \u4e2a\u5dee\u5f02\u8868\u8fbe\u57fa\u56e0\uff0884 \u4e2a\u4e0a\u8c03\uff0c352 \u4e2a\u4e0b\u8c03\uff09\u3002\u5bcc\u96c6\u5206\u6790\uff08GO\u3001KEGG\u3001PPI\uff09\u53d1\u73b0\u67098\u4e2a\u57fa\u56e0\u2014\u2014 CBL\u3001 PRKCA\u3001 SLC38A1\u3001 ZBTB16\u3001 AANAT\u3001 CYP1A1\u3001 SLC7A11 \u548c NTRK2\uff0c\u4e0e\u8272\u6c28\u9178\u4ee3\u8c22\u3001\u6c27\u5316\u5e94\u6fc0\u548c\u957f\u671f\u7a81\u89e6\u6291\u5236\u7b49\u901a\u8def\u76f8\u5173\u3002\u751f\u7269\u4fe1\u606f\u5b66\u548c\u53cc\u8367\u5149\u7d20\u9176\u62a5\u544a\u57fa\u56e0\u68c0\u6d4b\u8868\u660e\uff0cmiR-27a \u76f4\u63a5\u9776\u5411 PRKCA \u7684 3'-UTR\uff0c\u4ecb\u5bfc\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u7684\u6291\u5236\u3002\u6d3b\u4f53\u5b9e\u9a8c\u8868\u660e\uff0c\u5c0f\u9f20\u4e0b\u4e18\u8111\u5185\u6ce8\u5c04 mmu-miR-27a-3p \u4f1a\u964d\u4f4e\u5176\u8fd0\u52a8\u529f\u80fd\uff0c\u524a\u5f31\u5176\u793e\u4f1a\u652f\u914d\u5730\u4f4d\uff0c\u5e76\u4f7f\u5176\u5904\u4e8e\u7ade\u4e89\u52a3\u52bf\uff0c\u540c\u65f6\u6291\u5236\u5c0f\u9f20\u795e\u7ecf\u5143\u7684\u81ea\u566c\u3001\u7ec6\u80de\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002."

Selenium nanoparticles (Se-NPs) are neuroactive agents owing to their antioxidant and anti-inflammatory activities. Additionally, physical and mental activities (Ph&M) exert neuroprotective effects by optimizing the release of both neurotransmitters and growth factors. However, their neuroprotective effects against SI-induced depression are still poorly investigated. We aim to explore the neuroprotective effect of Se-NPs, Ph&M, and their combination to guard against the harmful effects of SI-induced depression in a rat model. Fifty Sprague Dawley rats were randomly allocated into five groups: control, SI, Ph&M, orally administered Se-NPs (0.1\u00a0mg/kg), and a combination group. Neuroprotective activity was quantitatively estimated pharmacologically, biochemically, histologically, and behaviorally. SI caused behavioral and biochemical alteration in the rat model, decreasing neurotransmitter levels, increasing the transcription of inflammatory response genes (TLR4 and NF-\u03baB), and consequently increasing the production of the cytokines TNF-\u03b1 and IL-1\u03b2. It also activated the proinflammatory NLRP3/caspase-1 pathway. The ER stress parameters PERK, CHOP, and GRP78 were significantly elevated. Impairment of autophagy and increased neurodegeneration were detected via the decline of AMPK/SIRT-1/Beclin-1 PI3K/AKT gene expression and m-TOR overexpression. Decreased expression of TrkB and CREB mRNA and consequent decline in brain-derived neurotropic factor were recorded. SI caused a drastic drop in Wnt3a and \u03b2-catenin levels and increased GSK3\u03b2 activity affecting neuroplasticity and cognitive functions. Administration of Se-NPs and/or application of Ph&M, especially their combination, provided significant protection against prior SI effects. Se-NPs and Ph&M, especially their combination, showed promising protective effects against neuroinflammation, oxidative stress, apoptosis and subsequent alterations of test animal behaviors precipitated by SI."

We investigated the role of CNOT11 in cellular stress responses using siRNA-mediated knockdown, immunoblotting, immunoprecipitation, transcriptomic analysis, quantitative RT-PCR, ELISA, cycloheximide chase assays, actinomycin D treatment, and poly(A) tail analysis. CNOT11 depletion did not markedly alter the expression of other CCR4-NOT subunits but reduced the association of CNOT10 with the complex. CNOT11 knockdown was associated with LC3-II accumulation, transcriptional upregulation of autophagy-related genes, and changes in AMPK/ULK1 signaling. Increased IL-6 expression and secretion and enhanced STAT1 and STAT3 phosphorylation were also observed. IL-6 knockdown or STAT3 inhibition partially attenuated LC3-II accumulation. Increased IL-6 expression was associated with elevated transcription, without detectable changes in mRNA stability or poly(A) tail length. These findings suggest that CNOT11 depletion is associated with LC3-II accumulation and other autophagy-related responses, with IL-6-JAK-STAT signaling contributing partially to this phenotype. Definitive assessment of autophagic flux and the causal positioning of IL-6 signaling will require further studies using gold-standard flux assays and IL-6 rescue or neutralization approaches."

Conversely, phase-separated condensates have also been associated with aberrant protein misfolding and subsequent aggregation in neurodegenerative disease-related processes. Protein phase separation and phase transitions involve the formation of heterogeneous and dynamic assemblies that can evolve into gel-like or semi-crystalline states, which are challenging to characterize using high-resolution structural biology techniques. Solid-state nuclear magnetic resonance (NMR) spectroscopy now offers a broad arsenal of methods to probe the structural and dynamic features of viscous condensates, elastic solids, coacervates and rigid protein assemblies. This review provides an overview of solid-state NMR approaches that are readily applicable and discusses potential methodological developments to investigate protein condensates and coacervates as well as to study protein phase separation and phase transitions."

However, liver sinusoidal endothelium-mediated nanoparticle elimination remains far less understood than liver macrophage uptake despite both processes being involved in hepatic detoxification. Using water-soluble Au25(o-MBA)18 (o-MBA: o-mercaptobenzoic acids) with optimized local hydrophobicity for weak protein-binding affinity and high endothelium targeting as probes, we report an exosome-mediated systemic clearance for endocytosed nanoclusters in sinusoidal endothelial cells. Au25(o-MBA)18 can effectively avoid phagocytosis by liver macrophage, are initially endocytosed by sinusoidal endothelial cells through clathrin-dependent endocytosis, processed through endosomal pathways, and released as exosomes containing nanoclusters into the bloodstream. During the exosome biogenesis, Au25(o-MBA)18 progressively transform into flower-like aggregates (approximately 100 nm). These circulating exosomes traverse the glomerular membrane through autophagy in glomerular endothelial cells and podocytes before urinary excretion. Here, this exosome-mediated pathway converts exogenous ultrasmall gold nanoparticles into biocompatible endogenous exosome-enveloped cargos for systemic circulation with reduced toxicity, providing a foundation for developing next generation of safe and effective nanomedicines."

Previously reported mouse models exhibited reduced birthrate and survival of affected males, greatly limiting their experimental utility. Here we describe a new mouse model carrying the clinically relevant Sms p.Gly56Ser (SmsG56S) allele in which viable males are recovered at Mendelian ratios, enabling generation of adequately powered cohorts. Hemizygous males produce markedly reduced SMS protein across tissues, recreating the biochemical hallmark of SRS, an elevated spermidine:spermine ratio. SmsG56S/Y males exhibit reduced body size, altered body composition, decreased locomotor and exploratory behaviors, and reduced seizure threshold, aligning with clinical features reported in SRS patients. Serum LDL, HDL, and cholesterol levels were reduced, while brain histology revealed modest region-specific astrocytic changes. Comprehensive polyamine profiling revealed tissue-specific biochemical disturbances, highlighting putrescine elevation in the brain and informing development of translational strategies and windows for intervention. Overall, this improved model reproduces multiple key aspects of the human SRS phenotype and provides a robust platform for mechanistic studies and preclinical evaluation of therapies."

The estrogen decline increases vulnerability to mood disorders, but the molecular mechanisms underlying stress resilience remain unclear. Here, we identify hippocampal neuronal progranulin (PGRN), a secreted neuroprotective glycoprotein, as a key regulator of affective resilience under estrogen-deficient conditions. Ovariectomy (OVX) reduces hippocampal neuronal PGRN expression and induces anxiety- and depression-like behaviors, whereas estradiol supplementation restores both PGRN levels and behavior. Adeno-associated virus (AAV)-mediated overexpression of PGRN alleviates affective deficits across OVX, 4\u2011vinylcyclohexene diepoxide (4-VCD)-induced ovarian failure, and natural aging models, while neuronal, but not microglial, Grn deletion exacerbates stress susceptibility. Mechanistically, PGRN restores lysosomal protease activity, normalizes autophagic flux, activates AMP-activated protein kinase (AMPK) phosphorylation, and rescues mushroom spine loss, thereby restoring cellular and synaptic homeostasis. Intracerebral recombinant PGRN rescues OVX\u2011induced behavioral deficits, and the blood-brain barrier (BBB)-permeable fragment granulin-E (GRN\u2011E) confers similar protection after systemic administration.

As a key transcription factor in reproductive modulation, the specific role of GATA4 in the testicular microenvironment of Bactrian camels remains unclear. This study investigates the expression patterns of GATA4 in the testicular tissue during estrus and anestrus phases, alongside its potential regulatory effects on Sertoli cells (SCs) function. Utilizing mRNA sequencing, we analyzed testicular samples in estrus (n\u202f=\u202f3) and anestrus (n\u202f=\u202f3), identifying 291 differentially expressed genes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed that GATA4 was involved in reproduction-related processes, including tight junction formation, autophagy, and cell cycle regulation. Notably, validation showed that GATA4 expression was significantly upregulated in testicular tissue during the anestrus period, with its protein localized primarily in SCs. Gain- and loss-of-function assays revealed that altered GATA4 expression is associated with changes in autophagy-related marker profiles, evidenced by a lower LC3II/LC3I ratio, decreased Beclin-1, and increased P62 expression level. Silencing GATA4 induced opposite alterations in these autophagy-associated molecular markers, and these molecular changes are associated with modified mTOR/NF-\u03baB pathway expression. Additionally, GATA4 influences SCs apoptosis and G0/G1 cell cycle arrest and these cellular phenotypic changes are accompanied by alterations in the PI3K/AKT pathway, which correlates with changed levels of BAX, Caspase-3, BCL2, and CDK1. And moreover, GATA4 modulates the expression of the tight junction markers ZO-1 and Occludin, and these remodeling events are associated with modified WNT1/\u03b2-catenin signaling. In conclusion, GATA4 exhibits dynamic expression patterns throughout the reproductive cycle, which correlates with the modulation of multiple biological processes in SCs, including autophagy-related marker remodeling, apoptosis regulation, and tight junction marker remodeling. This study's findings provide a key molecular target for elucidating the seasonal reproductive mechanism and reproductive regulation of Bactrian camels and enrich the current understanding of reproductive regulatory mechanisms in this species."

Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC).

Autophagy is essential for endothelial homeostasis, yet its role in aldosterone-mediated vascular dysfunction remains unclear. We tested whether aldosterone impairs autophagic flux and whether restoring autophagy via Beclin1 (BCN1) activation protects vascular and cardiac function. Endothelial and vascular responses to aldosterone were assessed in wild-type mice, BCN1 gain-of-function mice (Becn1), and mice treated with spermidine or a BCN1-activating TB-peptide. Vascular function, nitric oxide (NO)/reactive oxygen species (ROS) production, autophagy markers, endothelial migration, and cardiac fibrosis were evaluated using wire myography, fluorescence assays, Western blotting, confocal microscopy, migration assays, and histology. Aldosterone impaired endothelium-dependent relaxation, decreased NO, increased ROS, and disrupted autophagic flux in an MR-dependent manner, indicated by LC3 accumulation and reduced p62 and BCN1 expression. Spermidine restored endothelial function and normalized NO and ROS levels. BCN1 gain-of-function mice were protected from aldosterone-induced endothelial dysfunction and exhibited reduced coronary and myocardial fibrosis. TB-peptide activation of BCN1 enhanced autophagic flux, improved vascular function, decreased cardiac fibrosis, and rescued endothelial migration impaired by aldosterone. Aldosterone induces endothelial dysfunction by suppressing autophagic flux through MR activation. Genetic or pharmacologic enhancement of BCN1-dependent autophagy restores endothelial homeostasis and prevents vascular and cardiac injury, identifying autophagy activation as a promising therapeutic approach for cardiovascular diseases associated with mineralocorticoid excess."

The pathophysiology of SCI involves many aspects. Current treatments, such as early decompression and glucocorticoids, target single pathways and show limited efficacy with safety concerns. In this context, interventions based on the incretin system are now considered attractive candidates for SCI intervention. This review comprehensively outlines the mechanisms underlying microenvironmental imbalance following SCI and explores glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists as promising options. These agents, recognized for their role in managing diabetes and body weight, demonstrate substantial pleiotropic effects beyond simple glycemic regulation. These beneficial actions include neuroprotection, anti-inflammatory effects, and the promotion of tissue repair. Preclinical SCI studies have indicated that GLP-1 receptor agonists and GIP receptor agonists reduce inflammation by shifting microglia/macrophages to anti-inflammatory phenotypes, suppress apoptosis, increase autophagy, alleviate oxidative stress, promote axonal regeneration, improve the injury microenvironment, and have the potential to regulate immune cells. Related research in other neurological disorders supports these mechanisms, with dual agonists showing superior efficacy. GLP-1 receptor agonists and GIP receptor agonists suggest significant potential to address the multifaceted pathology and associated metabolic complications of SCI. Current evidence highlights the importance of mechanistic elucidation, dose optimization, the development of innovative delivery systems such as nanoparticles, and further validation in large animal and human studies."

Research indicates that IF enhances insulin sensitivity, facilitates weight reduction and stimulates cellular repair pathways, including autophagy. Physiological adaptations to fasting are reflected in favorable alterations in biomarkers and metabolic processes. This review examines the current evidence on IF by analyzing studies retrieved through schematic searches of the MEDLINE via PubMed database, Embase and ScienceDirect using specific keyword combinations. It focuses on commonly practiced regimens- Time-restricted eating (TRE) (16/8 method), Alternate-day fasting (ADF), the 5:2 intermittent energy-restriction diet and One meal a day (OMAD) approaches and explores their effects on cardiovascular function, metabolic regulation, cognitive performance and longevity. Various IF regimens including the TRE (16/8 method), ADF, the 5:2 diet and OMAD approaches are discussed in relation to their effects on cardiovascular health, cognitive function, metabolic regulation, aging and longevity. While most finding highlight significant health benefits, inconsistencies and methodological limitations are also reported. Mechanistically, IF orchestrates a coordinated metabolic response through modulation of key nutrient sensing pathway such as AMP activated protein kinase (AMPK), mechanistic target of rapamycin (mTOR) and unc-51-like kinase 1 (ULK1). These cascades interact with Sirtuins (SIRT1/3), peroxisome proliferator activated receptor gamma coactivator-1\u03b1 (PGC-1\u03b1) and the transcription factor EB (TFEB) to regulate autophagy, mitochondrial biogenesis, oxidative stress defense and cellular repair. Clinically, these molecular events underpin improvements in glycaemic control, lipid metabolism and inflammatory balance, supporting the therapeutic potential of IF for cardiometabolic disorders, neuroprotection and healthy aging."

No definitive methods exist to repair damaged neurons. Vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) are two neuroprotective agents that work synergistically. However, these large molecular proteins have difficulty crossing the blood-brain barrier (BBB). Extracellular vesicles (EVs) offer superior targeting and low immunogenicity, making them excellent carriers. In this study we examined the protective effects of VEGF and NGF in a cell model and evaluated the therapeutic potential of VEGF-NGF contained within EVs in PD rats. EVs were isolated using sequential differential centrifugation and characterized using transmission electron microscopy, nanoparticle tracking analysis, and western blotting (WB). VEGF and NGF were loaded into the EVs using a saponin-assisted method to create VEGF@EVs, NGF@EVs, and VEGF/NGF@EVs. The viability of 6-hydroxydopamine hydrochloride (6-OHDA)-induced SH-SY5Y cells was measured using the cell counting kit-8 assay before and after treatment with VEGF and NGF. Autophagy levels were assessed using WB, and the role of autophagy was further explored using the autophagy inhibitor chloroquine. Unilateral PD rat models were established via stereotactic injection of 6-OHDA into male Sprague-Dawley rats. Behavioral changes were monitored before and after treatment. Neuronal recovery, neurotransmitter levels, and autophagy levels in the rat brains were evaluated using immunohistochemistry, enzyme-linked immunosorbent assay, and WB. VEGF/NGF@EVs significantly enhanced the viability of 6-OHDA-induced SH-SY5Y cells. A complete autophagic process was identified as essential for this protective effect. The intranasal administration of VEGF/NGF@EVs improved motor behavior in PD rats, with performance better than that of single growth factor treatments. The number of tyrosine hydroxylase (TH)-positive neurons, TH protein expression, and dopamine content were significantly increased. In addition, the level of autophagy in the rat substantia nigra was elevated. VEGF/NGF@EVs exert protective effects in both in vitro and in vivo 6-OHDA-induced PD models by promoting autophagy, demonstrating greater efficacy than either growth factor alone. By transplanting VEGF/NGF@EVs into PD rats, we showed that these vesicles can effectively cross the BBB and deliver targeted therapy to the central nervous system. This study highlights the significant potential of EV-mediated protein transplantation strategies for treating neurological disorders."

Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities."

Despite advances in antiseizure medications, effective epilepsy management remains challenging because of pharmacoresistance, limited blood-brain barrier (BBB) permeability, inadequate intracerebral drug accumulation, and systemic toxicity. Moreover, currently available therapies primarily provide symptomatic seizure control without addressing the fundamental pathological processes involved in epileptogenesis, neuroinflammation, oxidative stress, and neuronal degeneration. Intranasal administration has emerged as an attractive non-invasive approach for direct brain targeting, enabling therapeutic agents to circumvent BBB-associated transport barriers and access the central nervous system through the olfactory and trigeminal neural pathways. In this context, biodegradable nanomedicine platforms have gained considerable attention due to their favorable biocompatibility, controlled drug release, enhanced mucosal permeation, and potential for targeted intracerebral delivery. This review provides a comprehensive and critical overview of recent advances in intranasal biodegradable nanomedicine for epilepsy, integrating current knowledge on disease pathophysiology, biological and pharmaceutical barriers, nose-to-brain transport mechanisms, biodegradable nanoparticle platforms, and emerging functionalization strategies. Importantly, the review critically evaluates the current evidence, distinguishing encouraging preclinical findings and discusses the major translational challenges that continue to hinder clinical implementation. Finally, future perspectives are highlighted to identify opportunities for developing safer, more effective, and clinically translatable therapies for epilepsy management."

Among those, the short isoform of Nuclear Receptor Coactivator 7 (NCOA7-AS) has been shown to inhibit IAV entry and more especially the fusion between endosomal and viral membranes. Ectopic expression of NCOA7-AS leads to the increased acidification of the endolysosomal pathway, putatively through NCOA7-AS interaction with the vacuolar ATPase (V-ATPase). However, the precise mechanism of action of NCOA7-AS is not fully understood. Here, we identified the cellular partners of NCOA7-AS by mass spectrometry, including the V-ATPase subunits known to interact with NCOA7-AS. A point mutation disrupting the interaction with the V-ATPase led to loss of antiviral activity against IAV, demonstrating that V-ATPase engagement is required for the antiviral phenotype. Moreover, sorting nexin (SNX) 1/2/5/6 were identified as novel partners of NCOA7-AS. These proteins are involved in retrograde transport of cellular cargoes from endosomes to the trans-Golgi network. We revealed that SNX5/6 interacted directly with NCOA7-AS and were essential for NCOA7-AS antiviral activity against IAV. Interestingly, crystal structures of NCOA7-AS/SNX5 complexes showed that the SNX5-interaction motif in NCOA7-AS was similar to those found in known cargoes of SNX5/6. In addition, we could pinpoint several critical residues that were important for binding and antiviral activity. Collectively, our study identifies novel essential partners for NCOA7-AS antiviral activity and the structural basis for their interaction."

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."

Moreover, we discuss the potential role of TMEM106B as an important modifier of the protein TDP-43 neuropathology associated with the GRN mutation in this case. The patient underwent detailed clinical assessment, serial neuropsychological evaluation, brain MRI, cerebrospinal fluid analysis, whole-exome sequencing, and next generation sequencing. A postmortem neuropathologic examination was performed to confirm the diagnosis. The patient presented slowly progressive paresthesia, cerebellar ataxia, dysarthria, and later cognitive and behavioral changes. Genetic testing revealed a heterozygous PRNP P102L variant and an unpenetrated GRN p.R110X variant; a protective TMEM106B polymorphism associated with TDP-43 pathology was also identified. Neuroimaging demonstrated progressive cerebellar and parietal atrophy with asymmetric left frontal opercular and insular involvement. The clinical course was dominated by a cerebellar GSS phenotype. The patient died 4 years after symptom onset. Neuropathology confirmed GSS, nevertheless without detectable TDP-43-associated neuropathology. This case highlights the diagnostic complexity of rare neurodegenerative disorders and illustrates that pathogenic variants may not influence phenotypic expression. Comprehensive genetic testing should be considered in atypical cases, as certain genetic variants may contribute to phenotypic variability and represent potential modifiers of phenotypic expression."

However, accumulating evidence over the past several decades has established them as the three principal endogenous gasotransmitters that regulate a wide spectrum of physiological and pathological processes. Unlike conventional signaling molecules, gasotransmitters diffuse freely across biological membranes and exert potent biological effects through receptor-independent mechanisms, including redox-sensitive post-translational modifications and modulation of heme-containing proteins. Although the individual functions of NO, CO, and H2S have been extensively reviewed, emerging studies indicate that these gaseous mediators rarely operate in isolation. Instead, they form a highly integrated signaling network characterized by direct chemical interactions, reciprocal enzymatic regulation, and convergence upon common downstream pathways. In this mini-review, we propose the concept of a \"Gasotransmitter Trio Network,\" emphasizing the molecular crosstalk among NO, CO, and H2S as a fundamental determinant of cellular homeostasis. We first summarize the biosynthetic pathways and major signaling mechanisms of the gasotransmitter trio, including S-nitrosylation, persulfidation, and heme-dependent regulation. We then discuss recent advances revealing how interactions among these gases generate novel bioactive intermediates and coordinate redox signaling. Particular attention is given to the emerging roles of gasotransmitters in regulating ferroptosis, autophagy, and mitophagy by modulating iron metabolism, lipid peroxidation, mitochondrial quality control, and antioxidant defense systems. These findings support a unified framework in which gasotransmitters function as master regulators of cellular fate under conditions of physiological and pathological stress. Finally, we highlight recent progress in stimuli-responsive donors, CO-releasing molecules (CORMs), NO-releasing materials (NORMs), H2S donors, and advanced nanoplatforms that enable spatiotemporally controlled gas delivery. We propose that future therapeutic strategies will increasingly rely on programmable multi-gas systems that recapitulate endogenous gasotransmitter networks. Collectively, this review provides a systems-level perspective on gasotransmitter biology and outlines emerging opportunities for the development of precision gas medicine in cardiovascular, neurodegenerative, inflammatory, metabolic, and malignant diseases."

Shikonin, a natural anti-tumor compound, exerts anti-BCa activity, yet its direct molecular target and underlying mechanism remain undefined. This study aimed to identify the direct target of shikonin in BCa and to elucidate the mechanism by which shikonin suppresses tumor progression. The anti-BCa effects of shikonin were assessed in vitro and in vivo. Drug affinity responsive target stability (DARTS) combined with 4D quantitative proteomics identified shikonin's direct target, which was validated by molecular docking and cellular thermal shift assay (CETSA). Gain- and loss-of-function experiments and ER-phagy-related assays elucidated the underlying molecular mechanism. Shikonin inhibited BCa cell proliferation, migration, invasion and induced senescence in vitro, and suppressed tumor growth in vivo with no obvious toxicity. Deoxyribonuclease 2 (DNASE2) was identified as shikonin's direct target; shikonin promoted DNASE2 ubiquitination and degradation without altering its mRNA level. DNASE2 was highly expressed in BCa and correlated with poor prognosis, and its knockdown mimicked and enhanced shikonin's anti-BCa effects. Mechanistically, shikonin targeted DNASE2 to downregulate Reticulon 3 (RTN3), thereby inhibiting RTN3-dependent endoplasmic reticulum autophagy (ER-phagy) in BCa. This study first identifies DNASE2 as the direct target of shikonin in BCa, and reveals that shikonin exerts anti-BCa activity by promoting DNASE2 ubiquitination/degradation to inhibit the DNASE2/RTN3 axis-mediated ER-phagy. The DNASE2/RTN3 axis is a novel ER-phagy regulatory node in BCa, providing a potential therapeutic target for BCa treatment."

Here, we investigate whether the CT Receptor plays a role in cancer cell survival. In cancer cell lines, knockdown of CALCR disrupts the cell cycle and induces apoptosis, supporting an essential pro-survival role. The CALCR gene produces three main transcripts in humans, of which Transcript 1 encodes CALCRb mRNA including exon 10 and is translated into the CTb Receptor isoform, and Transcripts 2 and 3 which are translated into the CTa Receptor. CALCRb expression is conserved across a diverse range of mammalian species. We examined the expression of all CT Receptor isoforms (CALCRtotal) and CALCRb expression in four high-grade glioma stem-like cell lines and in U-87 MG glioblastoma cells. Using qPCR, we observed stable levels of both CALCRtotal and CALCRb expression under conditions of autophagy or apoptosis, consistent with a requirement for CALCRb in cell survival. As alternative splicing (AS) of key genes in cancers confers tumour resilience, we investigated AS of CALCR transcript 2 using long-read nanopore sequencing. Unexpectedly, we discovered a novel AS event causing inclusion of exon 10 within Transcript 2 in all glioblastoma cell lines investigated. This finding, together with stable CALCRb expression under cellular stress and the finding by other groups confirming that knockdown of CT Receptor compromises cell survival, implicates the CTb Receptor as a potential oncoprotein."

How the predicted regulatory potential of these miRNAs differs among the milks of different animals most relevant to human nutrition has not been systematically compared. Here, we performed an integrative in silico analysis of publicly available small-RNA sequencing data from 29 milk and milk-cell samples of human, cow, goat, and donkey origin. miRNAs were quantified against human (hsa) miRBase references-thereby restricting the analysis to evolutionarily conserved miRNAs with human orthologs-and their predicted effect on the human transcriptome was modeled by integrating predicted (mirDIP database) and experimentally supported (TarBase v9 database) miRNA-target interactions into a per-gene, per-species weighted targeting score. Because miRNAs act predominantly as repressors, this score is read as a prediction of which genes would be post-transcriptionally down-regulated in a recipient. miR-148a-3p dominated the exosomal spectrum of all four species (human, cow, goat, and donkey; \u224821.5% of pooled abundance), and the twenty most abundant miRNAs accounted for roughly three quarters of the signal. Of 4577 robustly targeted genes, a 1809-gene conserved \"pan-milk\" core showed the highest cross-species targeting and was enriched for transcriptional regulation, PI3K-Akt, MAPK, and TGF-\u03b2/SMAD signaling, autophagy and-strikingly-the components of the RNA-interference machinery itself.

Across categories, we observed a reproducible confidence-exclusivity trade-off. We emphasize that these results are computational predictions that assume dietary miRNA uptake and do not constitute experimental validation. We provide the complete targetome as a hypothesis-generating resource to prioritize candidate genes, pathways, and milk types for future functional, nutritional, and epigenetic investigation. Across the 29 samples from the four species, miRNA composition segregated by species (silhouette width = 0.82, a cluster-separation measure ranging from -1 to 1, with values near 1 indicating well-separated groups) and the category structure exceeded a permutation null, indicating that the between-species signal is robust to differences in dataset origin and milk state."

On the other hand, excessive and prolonged ER stress leads to apoptosis. However, the relationships between different UPR branches and apoptosis or autophagy vary in cancer cells of different origins and depend on the extent and nature of the stress signal. This study was designed to establish the role of ER stress sensors protein kinase RNA-like endoplasmic reticulum kinase (PERK) and inositol-requiring enzyme 1 (IRE1\u03b1) in apoptosis or autophagy signaling in T-lymphoblastic leukemia MOLT-3 cells via the RNA interference method. The cells were transfected with small interfering RNAs (si-PERK, si-IRE1\u03b1, or si-Cont) for 6 h and further cultured under normal conditions for 72 h to provide an insight into chronic effects of the gene silencing. The expression of apoptosis and autophagy effectors at the mRNA and protein levels was compared using RT-PCR and Western blot assays, respectively. Transfection of the cells with PERK siRNA led to a significant decrease in PERK protein and gene expression, and decreased phosphorylation of its downstream effector eukaryotic initiation factor 2\u03b1 (eIF2\u03b1). PERK silencing was accompanied by activation of apoptosis-related genes and proteins-BCL2-associated X (Bax), caspase-3, C/EBP homologous protein (CHOP), while the levels of autophagy markers (Unc-51 like autophagy activating kinase 1 (ULK1), Beclin-1, and microtubule-associated proteins 1A/1B light chain 3 (LC3A/B)) remained stable. In contrast, treatment of the cells with si-IRE1\u03b1 reduced the content of IRE1\u03b1, X-box-binding protein 1 (sXBP1), and glucose-regulated protein 78 (GRP78) proteins, but increased ERN1 gene expression. IRE1\u03b1 RNA interference did not affect the levels of the pro-apoptotic marker Bax, but suppressed caspase-3, CHOP, c-Jun N-terminal kinase (JNK), and autophagy signaling molecules (ULK1, Beclin-1, LC3A/B) at both the transcriptional and translational levels. These results indicate that the PERK pathway is an important contributor to the survival of MOLT-3 cells under basal ER stress, while PERK depletion compromises the resistance of cells to UPR-mediated apoptosis. The IRE1\u03b1 UPR branch is directly linked with autophagy-dependent signaling, although IRE1\u03b1 knockdown exerted a more complicated influence on the cells, probably via activation of multiple pro-death and compensatory pro-survival regulatory mechanisms."

Many preclinical studies have shown promising results in Alzheimer's, Parkinson's, and Huntington's diseases. However, no NP-based therapy has moved beyond early-stage clinical trials. Several issues remain unresolved. Direct comparisons between different NP platforms are lacking. The long-term toxicity of NPs in the brain is not well understood. Animal models also do not accurately reflect human disease. We suggest that future work should focus on standardized characterization, better predictive models, and clinical trial designs that address NP diversity. Researchers should also compare NP therapies with existing treatments in a rigorous manner."

In contrast, plant-derived exosomes (PDEs), as natural nanovesicles, offer significant advantages as drug delivery carriers due to their large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers.

In U-87MG tumor-bearing mice, G-CDDP effectively targeted tumor sites and exhibited significant therapeutic effect.

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations."

Despite this commonality, most current therapeutic approaches in the field, such as anti-aggregate antibodies, are focused on individual diseases or single neuropathologies with only limited success. The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases. Thus, these proteins are predicted to participate in common pathogenic pathways shared across various neurodegenerative diseases. Importantly, recent discoveries of TMEM106B amyloid fibrils in varied neurodegenerative diseases and glycosphingolipid regulation by progranulin and TMEM106B further support their central roles in cross-disease neurodegenerative mechanisms. This review summarizes recent advances in progranulin and TMEM106B function within the endolysosomal system and neurodegenerative diseases. It describes preclinical models and therapeutic approaches for progranulin- and TMEM106B-associated diseases. We also discuss future direction leading to novel alternative therapies targeting shared mechanisms in neurodegenerative diseases."

Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC).

Nasal administration has emerged as a promising non-invasive route, bypassing the BBB via direct neural pathways (olfactory/trigeminal), systemic absorption, or lymphatic drainage. However, inherent nasal barriers like the mucus layer and epithelium limit its efficacy. This review distinguishes itself by integrating mechanistic insights into nasal transport pathways with the rational design of advanced nano-delivery systems. We first outline the challenges in CNS drug delivery and detail the nasal anatomy and transport pathways facilitating nose-to-brain delivery. Subsequently, we emphasize the critical properties required of advanced nano-carriers to improve mucosal penetration, prolong retention, and promote drug accumulation at cerebral injury sites. Following a detailed analysis of the advantages and limitations associated with nose-to-brain delivery, we consolidate recent advances in nasal nano-delivery systems for treating CNS disorders, emphasizing their capacity to improve brain-targeting efficiency, enhance therapeutic efficacy, reduce systemic toxicity, and enable previously undruggable CNS targets. Finally, we expand the discussion to encompass current challenges impeding clinical translation, including safety concerns, manufacturing scalability, and regulatory hurdles, while highlighting emerging trends such as artificial intelligence-driven formulation design. This comprehensive analysis aims to deepen the understanding of nasal-to-brain transport mechanisms and inform the future development of effective nasal formulations for improved neurological therapeutics."

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity."

While cobalt ions are linked to neurodegenerative diseases, the neurodevelopmental toxicity of Co3O4 NPs remains poorly understood. Ferroptosis, a process regulated by iron homeostasis, can be triggered by ferrous overload through ferritinophagy. This study explores how Co3O4 NPs induce ferritinophagy and their role in neurodevelopmental toxicity. Zebrafish larvae exposed to Co3O4 NPs at concentrations of 0, 5, and 50\u202fmg/L for up to 120\u202fh post-fertilization (hpf) exhibited dose-dependent developmental toxicity, including delayed hatching, increased malformations, and impaired motor behavior. Transgenic zebrafish models demonstrated neuronal shortening, reduced fluorescence, and altered neurotransmitter profiles, as supported by liquid chromatography-tandem mass spectrometry. Co3O4 NPs induced oxidative stress, leading to iron overload, lipid peroxidation (elevated MDA, depleted glutathione), and ferritinophagy activation, as evidenced by changes in genes and proteins related to iron metabolism (trf, fpn, slc7a11) and ferroptosis (GPX4, ACSL4, FTH1, NCOA4). Ferritinophagy was further confirmed using autophagy inhibitors, demonstrating its role in neurotoxicity. Additionally, Vitamin E (d-\u03b1-tocopherol), a lipid-soluble antioxidant that suppresses lipid peroxidation, reduced neurodevelopmental abnormalities, supporting that Co3O4 NP-induced toxicity occurs through ferritinophagy-mediated ferroptosis, leading to neurotransmitter dysregulation. These findings were corroborated in human neuroblastoma cells (SH-SY5Y/SK-N-SH). In conclusion, Co3O4 NPs disrupt iron homeostasis, activate ferritinophagy, and induce ferroptosis, resulting in neurotransmitter dysregulation and neurodevelopmental toxicity. These results provide new insights for assessing the neurodevelopmental toxicity and environmental risk of Co3O4 NPs and similar nanomaterials."

"abstract_text": "ID: 42576524\nTitle: The Double-Edged Sword: A Structured Narrative Review of Microglial Phenotypic Transition as a Pivotal Driver and Therapeutic Target in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder primarily involving the loss of dopaminergic neurons and pathological \u03b1-synuclein (\u03b1-syn) aggregation. A pivotal feature of PD pathogenesis is the dual role of microglia, which shifts from maintaining neuronal homeostasis to driving neuroinflammation and neurodegeneration. The mechanisms underlying this functional transition and its consequences for disease progression require a comprehensive synthesis. A structured PubMed search was performed using the keywords \"Parkinson's disease\", \"microglia\", \"neuroinflammation\", \"\u03b1-synuclein\", \"polarization\", \"tunneling nanotubes (TNTs)\", \"NF-\u03baB\", and \"NLRP3\". Relevant combinations of these terms were also used. A total of 2952 records were retrieved up to December 2025. Of these, 147 studies were included based on relevance to microglial polarization, neuroinflammation, \u03b1-syn-related pathology, and intercellular communication mechanisms. In early PD stages, microglia exert neuroprotective effects by transferring excess neuronal \u03b1-syn via TNTs, delivering healthy mitochondria, and clearing \u03b1-syn through autophagy. With disease progression, accumulated \u03b1-syn promotes microglial polarization toward the M1 phenotype. This shift activates TLR2/4, TREM2, MHCII, and RAGE receptors, triggering NF-\u03baB/NLRP3 pathways, releasing pro-inflammatory cytokines, and generating NOX2-derived ROS. The resulting neuroinflammatory cascade not only damages dopaminergic neurons directly but also disrupts astrocyte function and blood-brain barrier integrity, creating a self-perpetuating cycle of inflammation and neurodegeneration. These findings support dysregulated microglial polarization as an important component of PD pathobiology, but the available evidence remains weighted toward preclinical models. Future work should better define the timing, heterogeneity, and clinical measurability of microglial state transitions before microglia-targeted strategies can be translated with confidence. Microglial polarization may represent a potential therapeutic direction in Parkinson's disease, although further mechanistic and clinical validation and more precise biomarker definition remain necessary."

Dysregulation of these processes is implicated in numerous diseases, including cancer, liver disorders, and neurodegenerative diseases. p62/Sequestosome 1 (SQSTM1) is a multifunctional protein that plays a central role in protein homeostasis and stress responses by regulating autophagy and signal transduction pathways. Through its multiple protein-interacting domains, p62 functions both as a scaffold for selective autophagic degradation and as a signaling hub. Since our previous review of p62 a decade ago, substantial progress has been made in elucidating its molecular functions and physiological roles. Notably, p62 undergoes liquid-liquid phase separation with ubiquitinated proteins to form membraneless condensates, termed p62 bodies, when cells are exposed to proteotoxic stress. By sequestering specific proteins, p62 bodies act as platforms for autophagy-dependent degradation and stress signaling. These findings have substantially revised our view of p62 function, which was previously considered primarily as a receptor simply linking ubiquitinated substrates to autophagic membranes and connecting signaling molecules. This conceptual shift from one-to-one molecular interactions to multivalent, multimolecular, higher-order assemblies has fundamentally redefined the functional landscape of p62. In this review, we highlight how p62 bodies integrate selective autophagy and stress signaling, with a particular emphasis on their emerging roles in disease pathogenesis and their potential as therapeutic targets."

Although \u03b1-syn aggregation is considered central to PD pathogenesis, increasing evidence suggests that \u03b1-syn abundance may be as important as its conformational state. Genetic studies have demonstrated an SNCA dosage effect, with gene duplication and triplication associated with progressively more severe familial PD phenotypes. Complementary evidence indicates that dysfunction of protein clearance pathways, particularly the autophagy-lysosome system, promotes intracellular \u03b1-syn accumulation and increases its neurotoxic potential. In this review, we propose \u03b1-syn multiplication as an integrative framework for interpreting PD pathogenesis. This concept extends beyond SNCA copy-number variation to encompass processes that increase the effective \u03b1-syn burden within neurons or across neural networks, including increased gene expression, impaired degradation, disrupted proteostasis, and pathological propagation. We summarize \u03b1-syn structural dynamics and the concentration-dependent distribution of monomeric, oligomeric, and fibrillar species. We then review evidence from SNCA gene-dosage studies and examine the role of the autophagy-lysosome pathway in regulating \u03b1-syn homeostasis, with particular emphasis on recent experimental findings demonstrating that autophagy deficiency exacerbates \u03b1-syn accumulation and neurodegeneration in human \u03b1-syn bacterial artificial chromosome transgenic mice. Collectively, the available genetic, biochemical, and experimental evidence supports a model in which the balance between \u03b1-syn production and clearance influences disease progression alongside protein misfolding. The interaction between increased protein burden and impaired clearance capacity provides a unifying mechanism linking familial and sporadic forms of PD. We propose that \u03b1-syn multiplication offers an integrative framework for understanding PD pathogenesis, provides a quantitative perspective on disease heterogeneity, and highlights therapeutic opportunities aimed at reducing \u03b1-syn burden and restoring proteostatic balance."

In this study, circular RNA circAP2B1 is identified as a critical regulatory molecule that is markedly upregulated in ESCC tissues and patient serum and strongly associated with poor prognosis. Mechanistically, tumor-derived exosomes efficiently deliver circAP2B1 to tumor-associated macrophages (TAMs), where it serves as a distinct molecular scaffold that simultaneously binds the transcription factor ESRRA and the nuclear import receptor KPNA1, facilitating ternary complex formation and ESRRA nuclear translocation. Once in the nucleus, ESRRA directly activates the transcription of Mitofusin 2 (MFN2), a pivotal regulator of mitochondrial fusion, thereby enhancing mitochondrial oxidative phosphorylation, improving ATP production efficiency, and establishing a metabolically optimized intracellular environment that ultimately drives TAMs toward a pro-tumor M2 phenotype. Both in vitro and in vivo experiments demonstrate that targeted intervention of the circAP2B1/ESRRA/KPNA1/MFN2 signaling axis effectively reverses M2 polarization and markedly suppresses tumor progression. This study uncovers a novel exosomal circRNA-mediated metabolic-immune regulatory pathway and offers new avenues for the diagnosis and treatment of ESCC. The findings not only expand the understanding of circRNA functions in tumor immunity but also provide a theoretical basis for the development of therapies targeting the metabolic-immune axis."

Exosomes derived from adipose-derived mesenchymal stem cells (ADMSC-Exo) have robust protective effects under non-otologic ischemic conditions. However, their otoprotective effects remain unclear. This study aimed to investigate the protective effects of human ADMSC-Exo against cochlear damage and mitochondrial dysfunction under oxygen-glucose deprivation (OGD), an in vitro and ex vivo model of cochlear ischemia. ADMSC-Exo attenuated OGD-induced cytotoxicity and apoptosis in HEI-OC1 cells and reduced the OGD-induced loss of cochlear hair cells in the organ of Corti explants. OGD caused a decrease in mitochondrial mass and mitochondrial membrane potential depolarization and impaired mitochondrial respiration in auditory cells. ADMSC-Exo preserved mitochondrial integrity and improved mitochondrial bioenergetic function following OGD exposure. These effects were accompanied by increased LC3-II conversion and formation of autolysosome-like structures and elevated expression of PINK1 and Parkin, indicating the activation of autophagy and mitophagy-related protective mechanisms. Importantly, 3-methyladenine, an autophagy inhibitor, attenuated the cytoprotective effect of ADMSC-Exo, supporting the involvement of autophagy in ADMSC-Exo-mediated protection. Collectively, these findings suggest that ADMSC-Exo protect against OGD-induced cochlear injury by promoting autophagy-associated mitochondrial protection."

Recent studies have demonstrated that the gut microbiota acts as an important metabolic regulator and may play a pivotal role in the onset and progression of PCOS. Patients with PCOS frequently exhibit gut microbiota dysbiosis, which is characterized by reduced microbial diversity, decreased levels of beneficial bacteria, increased levels of pathogenic bacteria, and altered metabolic byproducts. This imbalance may contribute to IR and ovarian dysfunction by activating the toll-like receptor 4/nuclear factor kappa B inflammatory pathway, inducing oxidative stress, and disrupting Wnt/\u03b2-catenin signaling. The Wnt/\u03b2-catenin signaling pathway, a key regulator of follicular development, is frequently aberrantly activated in PCOS.

To this end, we conducted a comprehensive literature search across PubMed, Web of Science, Embase, and Cochrane Library databases, covering publications from January 2012 to March 2026.

Bone marrow mesenchymal stem cells-derived-exosomes (BMSCs-Exos) regulate osteoclast differentiation and osteoporosis in recent studies. But the mechanisms are still unclear. This research aimed to explore the mechanisms of BMSCs-Exos in osteoclast differentiation and osteoporosis. Exosomes were extracted from BMSCs. THP-1\u202fcells were cultured and treated with BMSCs-Exos. Osteoclast- and autophagy-related gene expression was assessed by qPCR and Western blot, the regulation of YAP1 by RBM15B was analyzed by MeRIP and RNA pull-down, osteoclast differentiation was detected by TRAP staining. HE staining, immunohistochemical staining and micro-CT were employed to assess the impact of BMSCs-Exos on osteoporosis. BMSCs-Exos were internalized by THP-1\u202fcells, promoted YAP1 expression and autophagy, and inhibited osteoclast differentiation.

Hippocampal downregulated proteins enriched in synaptic vesicle cycling, oxidative phosphorylation, and apoptosis, suggesting synaptic-mitochondrial disruption; upregulated proteins associated with ER stress and chaperone-mediated autophagy, suggesting proteostatic adaptation. Cortical candidate DEPs reflected suppressed mitochondrial function alongside enhanced translation and cytoskeletal remodeling. These region- and direction-specific changes were consistently observed across all bioinformatic platforms. The hippocampus showed pronounced synaptic and mitochondrial alterations, while the cortex exhibited cytoskeletal changes and metabolic shifts. In conclusion, Propofol induces distinct neurotoxic proteomic signatures in the neonatal hippocampus and cortex, suggesting compartment-specific vulnerability and compensatory remodeling.

Emphasis is placed on recent innovations involving polymeric, lipid-based, and vesicular carriers, along with the incorporation of mucoadhesive and permeation-enhancing agents. The present focus is enhancing bioavailability, prolonging drug residence time, and minimizing systemic toxicity. Surface modifications of nanocarriers further facilitates mucosal adhesion and enables effective nose-to-brain transport of encapsulated therapeutic agents. However, clinical translation remains challenging due to interindividual variability in nasal physiology, scalability constraints, and regulatory complexities. Future progress will depend on the rational design of multifunctional nanocarriers, integration of mucoadhesive and stimuli-responsive components, and the use of precision-based formulation strategies."

Understanding these modules and how they evolve over time can be accomplished by constructing gene regulatory networks (GRNs). To identify context-specific TF subnetworks, we developed ChEA-KG, which generates enriched TF regulatory subnetworks for input gene sets. ChEA-KG is based on a GRN connecting 1559 human TFs via 131\u2009181 signed and directed edges inferred from diverse published ChIP-seq (chromatin immunoprecipitation followed by sequencing) and mRNA (messenger RNA)-sequencing experiments. We demonstrate ChEA-KG's utility by applying it to uncover master regulators of aging, mechanisms of action (MoA) for drug classes, pan-cancer subtypes, and cell types from across 14 major human tissues. Next, we extend ChEA-KG to develop the webserver application ChEA-KG Time Series (ChEA-KG-TS), which identifies TF modules from time-series mRNA-sequencing datasets. Results from this workflow are automatically summarized as reports that include enrichment analysis, regulatory subnetworks, and UMAP projections of enriched TFs.

However, the blood-brain barrier (BBB) prevents over 98% of therapeutics from reaching brain tissue. Intranasal delivery provides a promising alternative by exploiting olfactory and trigeminal nerve pathways to circumvent the BBB. This review surveys recent advances in nose-to-brain delivery technologies, from carrier design to evaluation methods. Polymeric and lipid-based nanocarriers show enhanced mucosal penetration and prolonged residence time, and microneedle platforms further enable controlled drug release with minimal discomfort. To evaluate these delivery strategies, sensor-integrated organ-on-chip models provide more physiologically relevant testing than static cultures. Although persistent challenges such as rapid mucociliary clearance and formulation stability remain, combining nanotechnology with microfluidic devices and computational modeling shows potential for developing patient-specific therapeutics."

Consequently, this route has been extensively investigated for treating diverse brain disorders, ranging from acute conditions to neurodegenerative diseases. Despite the advantages and clinical approval of several nasal products, the need for effective disease-modifying therapies (DMTs) of brain disorders remains unmet. Given that most brain disorders involve region-specific or cell-type-specific pathological changes, and that off-target effects may result in central nervous system toxicity, precision nose-to-brain delivery is critical. A major challenge to its clinical translation remains the lack of predictive, human-relevant preclinical models. Therefore, this review explores the challenges in nose-to-brain drug delivery development, highlights advanced intranasal delivery strategies for treating brain disorders, and discusses emerging in vitro models for evaluating nose-to-brain delivery efficiency. The work aims to promote the development and clinical translation of intranasal brain-targeted therapeutics."

The blood-brain barrier (BBB), systemic toxicity, and first-pass metabolism are key obstacles. These factors limit the effective drug delivery to the brain. Intranasal administration has emerged as a noninvasive strategy to bypass the BBB. This approach enables direct drug delivery to the brain through the olfactory and trigeminal nerve pathways, commonly referred to as nose-to-brain (N2B) delivery. In this context, chitosan (CS), a biocompatible and mucoadhesive polysaccharide with permeation-enhancing properties, has gained significant interest as a functional material for nanoparticle (NP) engineering. CS-based or CS-coated NP can prolong the residence time on the nasal mucosa and facilitate drug transport to the CNS. This review provides a comprehensive overview of recent advances in CS-based NP for N2B drug delivery across a range of CNS disorders, including neurodegenerative, neuropsychiatric, neoplastic, and infectious conditions. Particular attention is given to formulation strategies, mechanistic insights, and preclinical outcomes. Recent patent applications are surveyed to underscore the translational potential and commercial interest in this technology. Collectively, CS-based NPs effectively address major therapeutic barriers, establishing a transformative and innovative platform in CNS drug delivery."

"abstract_text": "ID: 42546981\nTitle: New insights on microglial lysosomal acidification: A therapeutic target of neurodegenerative diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), maintain brain homeostasis and respond to pathological insults. Microglial dysfunction has been implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Impaired lysosomal function, particularly defective lysosomal acidification, leads to the accumulation of undegraded material, thereby promoting neuroinflammation and neuronal damage. This review examines the mechanisms governing lysosomal acidification in microglia and evaluates its potential as both a therapeutic target and a prognostic biomarker in neurodegenerative diseases. The literature on microglial lysosomal acidification, lysosomal pH regulation, autophagy, and neurodegeneration was searched in PubMed, Scopus, and Web of Science. Relevant mechanistic, preclinical, and translational studies were critically appraised and synthesized. Lysosomal acidification is increasingly recognized as a key regulator of microglial function and homeostasis. Defective acidification, driven by dysregulation of the vacuolar H+-ATPase (V-ATPase) proton pump, TFEB/TFE3 signaling pathways, and lysosomal ion channels such as TRPML1 and TMEM175, impairs autophagic flux and substrate degradation, facilitating the accumulation of neurotoxic aggregates including amyloid-\u03b2 and \u03b1-synuclein. Emerging evidence suggests that the degree of microglial lysosomal acidification may serve as a prognostic biomarker for disease progression and therapeutic response. Restoration or enhancement of lysosomal acidification through pharmacological modulation of lysosomal pH, activation of autophagy, or targeting of key regulatory pathways has been shown to re-establish microglial homeostasis, attenuate neuroinflammation, and confer neuroprotection in preclinical models. Restoration of microglial lysosomal acidification represents a promising therapeutic strategy for neurodegenerative diseases. A deeper understanding of the molecular mechanisms regulating lysosomal acidification in microglia may facilitate the identification of novel biomarkers and therapeutic targets, ultimately contributing to the development of innovative interventions for neurodegenerative disorders."

This research investigates the role of autophagy in renal damage caused by GoAstV in goslings. The findings indicated that GoAstV infection in goslings resulted in characteristic clinical manifestations, with renal tissues displaying tubular swelling, inflammatory infiltration, and autophagosome formation. In vivo experiments demonstrated a significant upregulation of mRNA levels for autophagy-related factors, including AMPK, LC3A, ATG5, ATG7, P62, Beclin1, AMBRA1 and GABARAPL1, while mTOR and LC3B levels were notably decreased. At 3 dpi, the protein expression levels of ATG5, Beclin1, and LC3B II/I increased, while P62 levels decreased, suggesting autophagy activation. In vitro analyses revealed that GoAstV infection led to enhanced autophagy; however, the concurrent upregulation of LC3B II/I and P62 proteins suggested an obstruction in the autophagic flux. Upon the inhibition of autophagy with 3-methyladenine (3-MA, autophagy inhibitor), there was a significant reduction in the expression of autophagy-related factors, accompanied by a marked decrease in viral replication rates. In conclusion, GoAstV infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux. The virus exploits autophagosomes for replication, ultimately resulting in kidney damage. The application of 3-MA effectively inhibits this autophagic process and diminishes viral replication."

Selenium nanoparticles (Se-NPs) are neuroactive agents owing to their antioxidant and anti-inflammatory activities. Additionally, physical and mental activities (Ph&M) exert neuroprotective effects by optimizing the release of both neurotransmitters and growth factors. However, their neuroprotective effects against SI-induced depression are still poorly investigated. We aim to explore the neuroprotective effect of Se-NPs, Ph&M, and their combination to guard against the harmful effects of SI-induced depression in a rat model. Fifty Sprague Dawley rats were randomly allocated into five groups: control, SI, Ph&M, orally administered Se-NPs (0.1\u00a0mg/kg), and a combination group. Neuroprotective activity was quantitatively estimated pharmacologically, biochemically, histologically, and behaviorally. SI caused behavioral and biochemical alteration in the rat model, decreasing neurotransmitter levels, increasing the transcription of inflammatory response genes (TLR4 and NF-\u03baB), and consequently increasing the production of the cytokines TNF-\u03b1 and IL-1\u03b2. It also activated the proinflammatory NLRP3/caspase-1 pathway. The ER stress parameters PERK, CHOP, and GRP78 were significantly elevated. Impairment of autophagy and increased neurodegeneration were detected via the decline of AMPK/SIRT-1/Beclin-1 PI3K/AKT gene expression and m-TOR overexpression. Decreased expression of TrkB and CREB mRNA and consequent decline in brain-derived neurotropic factor were recorded. SI caused a drastic drop in Wnt3a and \u03b2-catenin levels and increased GSK3\u03b2 activity affecting neuroplasticity and cognitive functions. Administration of Se-NPs and/or application of Ph&M, especially their combination, provided significant protection against prior SI effects.

We investigated the role of CNOT11 in cellular stress responses using siRNA-mediated knockdown, immunoblotting, immunoprecipitation, transcriptomic analysis, quantitative RT-PCR, ELISA, cycloheximide chase assays, actinomycin D treatment, and poly(A) tail analysis. CNOT11 depletion did not markedly alter the expression of other CCR4-NOT subunits but reduced the association of CNOT10 with the complex. CNOT11 knockdown was associated with LC3-II accumulation, transcriptional upregulation of autophagy-related genes, and changes in AMPK/ULK1 signaling. Increased IL-6 expression and secretion and enhanced STAT1 and STAT3 phosphorylation were also observed. IL-6 knockdown or STAT3 inhibition partially attenuated LC3-II accumulation. Increased IL-6 expression was associated with elevated transcription, without detectable changes in mRNA stability or poly(A) tail length. These findings suggest that CNOT11 depletion is associated with LC3-II accumulation and other autophagy-related responses, with IL-6-JAK-STAT signaling contributing partially to this phenotype. Definitive assessment of autophagic flux and the causal positioning of IL-6 signaling will require further studies using gold-standard flux assays and IL-6 rescue or neutralization approaches."

Conversely, phase-separated condensates have also been associated with aberrant protein misfolding and subsequent aggregation in neurodegenerative disease-related processes. Protein phase separation and phase transitions involve the formation of heterogeneous and dynamic assemblies that can evolve into gel-like or semi-crystalline states, which are challenging to characterize using high-resolution structural biology techniques. Solid-state nuclear magnetic resonance (NMR) spectroscopy now offers a broad arsenal of methods to probe the structural and dynamic features of viscous condensates, elastic solids, coacervates and rigid protein assemblies.

However, liver sinusoidal endothelium-mediated nanoparticle elimination remains far less understood than liver macrophage uptake despite both processes being involved in hepatic detoxification. Using water-soluble Au25(o-MBA)18 (o-MBA: o-mercaptobenzoic acids) with optimized local hydrophobicity for weak protein-binding affinity and high endothelium targeting as probes, we report an exosome-mediated systemic clearance for endocytosed nanoclusters in sinusoidal endothelial cells. Au25(o-MBA)18 can effectively avoid phagocytosis by liver macrophage, are initially endocytosed by sinusoidal endothelial cells through clathrin-dependent endocytosis, processed through endosomal pathways, and released as exosomes containing nanoclusters into the bloodstream. During the exosome biogenesis, Au25(o-MBA)18 progressively transform into flower-like aggregates (approximately 100 nm). These circulating exosomes traverse the glomerular membrane through autophagy in glomerular endothelial cells and podocytes before urinary excretion. Here, this exosome-mediated pathway converts exogenous ultrasmall gold nanoparticles into biocompatible endogenous exosome-enveloped cargos for systemic circulation with reduced toxicity, providing a foundation for developing next generation of safe and effective nanomedicines."

Previously reported mouse models exhibited reduced birthrate and survival of affected males, greatly limiting their experimental utility. Here we describe a new mouse model carrying the clinically relevant Sms p.Gly56Ser (SmsG56S) allele in which viable males are recovered at Mendelian ratios, enabling generation of adequately powered cohorts. Hemizygous males produce markedly reduced SMS protein across tissues, recreating the biochemical hallmark of SRS, an elevated spermidine:spermine ratio. SmsG56S/Y males exhibit reduced body size, altered body composition, decreased locomotor and exploratory behaviors, and reduced seizure threshold, aligning with clinical features reported in SRS patients. Serum LDL, HDL, and cholesterol levels were reduced, while brain histology revealed modest region-specific astrocytic changes. Comprehensive polyamine profiling revealed tissue-specific biochemical disturbances, highlighting putrescine elevation in the brain and informing development of translational strategies and windows for intervention. Overall, this improved model reproduces multiple key aspects of the human SRS phenotype and provides a robust platform for mechanistic studies and preclinical evaluation of therapies."

The estrogen decline increases vulnerability to mood disorders, but the molecular mechanisms underlying stress resilience remain unclear. Here, we identify hippocampal neuronal progranulin (PGRN), a secreted neuroprotective glycoprotein, as a key regulator of affective resilience under estrogen-deficient conditions. Ovariectomy (OVX) reduces hippocampal neuronal PGRN expression and induces anxiety- and depression-like behaviors, whereas estradiol supplementation restores both PGRN levels and behavior. Adeno-associated virus (AAV)-mediated overexpression of PGRN alleviates affective deficits across OVX, 4\u2011vinylcyclohexene diepoxide (4-VCD)-induced ovarian failure, and natural aging models, while neuronal, but not microglial, Grn deletion exacerbates stress susceptibility. Mechanistically, PGRN restores lysosomal protease activity, normalizes autophagic flux, activates AMP-activated protein kinase (AMPK) phosphorylation, and rescues mushroom spine loss, thereby restoring cellular and synaptic homeostasis. Intracerebral recombinant PGRN rescues OVX\u2011induced behavioral deficits, and the blood-brain barrier (BBB)-permeable fragment granulin-E (GRN\u2011E) confers similar protection after systemic administration.

As a key transcription factor in reproductive modulation, the specific role of GATA4 in the testicular microenvironment of Bactrian camels remains unclear. This study investigates the expression patterns of GATA4 in the testicular tissue during estrus and anestrus phases, alongside its potential regulatory effects on Sertoli cells (SCs) function. Utilizing mRNA sequencing, we analyzed testicular samples in estrus (n\u202f=\u202f3) and anestrus (n\u202f=\u202f3), identifying 291 differentially expressed genes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed that GATA4 was involved in reproduction-related processes, including tight junction formation, autophagy, and cell cycle regulation. Notably, validation showed that GATA4 expression was significantly upregulated in testicular tissue during the anestrus period, with its protein localized primarily in SCs. Gain- and loss-of-function assays revealed that altered GATA4 expression is associated with changes in autophagy-related marker profiles, evidenced by a lower LC3II/LC3I ratio, decreased Beclin-1, and increased P62 expression level. Silencing GATA4 induced opposite alterations in these autophagy-associated molecular markers, and these molecular changes are associated with modified mTOR/NF-\u03baB pathway expression. Additionally, GATA4 influences SCs apoptosis and G0/G1 cell cycle arrest and these cellular phenotypic changes are accompanied by alterations in the PI3K/AKT pathway, which correlates with changed levels of BAX, Caspase-3, BCL2, and CDK1. And moreover, GATA4 modulates the expression of the tight junction markers ZO-1 and Occludin, and these remodeling events are associated with modified WNT1/\u03b2-catenin signaling. In conclusion, GATA4 exhibits dynamic expression patterns throughout the reproductive cycle, which correlates with the modulation of multiple biological processes in SCs, including autophagy-related marker remodeling, apoptosis regulation, and tight junction marker remodeling. This study's findings provide a key molecular target for elucidating the seasonal reproductive mechanism and reproductive regulation of Bactrian camels and enrich the current understanding of reproductive regulatory mechanisms in this species."

Autophagy is essential for endothelial homeostasis, yet its role in aldosterone-mediated vascular dysfunction remains unclear. We tested whether aldosterone impairs autophagic flux and whether restoring autophagy via Beclin1 (BCN1) activation protects vascular and cardiac function. Endothelial and vascular responses to aldosterone were assessed in wild-type mice, BCN1 gain-of-function mice (Becn1), and mice treated with spermidine or a BCN1-activating TB-peptide. Vascular function, nitric oxide (NO)/reactive oxygen species (ROS) production, autophagy markers, endothelial migration, and cardiac fibrosis were evaluated using wire myography, fluorescence assays, Western blotting, confocal microscopy, migration assays, and histology. Aldosterone impaired endothelium-dependent relaxation, decreased NO, increased ROS, and disrupted autophagic flux in an MR-dependent manner, indicated by LC3 accumulation and reduced p62 and BCN1 expression. Spermidine restored endothelial function and normalized NO and ROS levels. BCN1 gain-of-function mice were protected from aldosterone-induced endothelial dysfunction and exhibited reduced coronary and myocardial fibrosis. TB-peptide activation of BCN1 enhanced autophagic flux, improved vascular function, decreased cardiac fibrosis, and rescued endothelial migration impaired by aldosterone. Aldosterone induces endothelial dysfunction by suppressing autophagic flux through MR activation. Genetic or pharmacologic enhancement of BCN1-dependent autophagy restores endothelial homeostasis and prevents vascular and cardiac injury, identifying autophagy activation as a promising therapeutic approach for cardiovascular diseases associated with mineralocorticoid excess."

The pathophysiology of SCI involves many aspects. Current treatments, such as early decompression and glucocorticoids, target single pathways and show limited efficacy with safety concerns. In this context, interventions based on the incretin system are now considered attractive candidates for SCI intervention. This review comprehensively outlines the mechanisms underlying microenvironmental imbalance following SCI and explores glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists as promising options. These agents, recognized for their role in managing diabetes and body weight, demonstrate substantial pleiotropic effects beyond simple glycemic regulation. These beneficial actions include neuroprotection, anti-inflammatory effects, and the promotion of tissue repair. Preclinical SCI studies have indicated that GLP-1 receptor agonists and GIP receptor agonists reduce inflammation by shifting microglia/macrophages to anti-inflammatory phenotypes, suppress apoptosis, increase autophagy, alleviate oxidative stress, promote axonal regeneration, improve the injury microenvironment, and have the potential to regulate immune cells. Related research in other neurological disorders supports these mechanisms, with dual agonists showing superior efficacy. GLP-1 receptor agonists and GIP receptor agonists suggest significant potential to address the multifaceted pathology and associated metabolic complications of SCI. Current evidence highlights the importance of mechanistic elucidation, dose optimization, the development of innovative delivery systems such as nanoparticles, and further validation in large animal and human studies."

Physiological adaptations to fasting are reflected in favorable alterations in biomarkers and metabolic processes. This review examines the current evidence on IF by analyzing studies retrieved through schematic searches of the MEDLINE via PubMed database, Embase and ScienceDirect using specific keyword combinations. It focuses on commonly practiced regimens- Time-restricted eating (TRE) (16/8 method), Alternate-day fasting (ADF), the 5:2 intermittent energy-restriction diet and One meal a day (OMAD) approaches and explores their effects on cardiovascular function, metabolic regulation, cognitive performance and longevity. Various IF regimens including the TRE (16/8 method), ADF, the 5:2 diet and OMAD approaches are discussed in relation to their effects on cardiovascular health, cognitive function, metabolic regulation, aging and longevity. While most finding highlight significant health benefits, inconsistencies and methodological limitations are also reported. Mechanistically, IF orchestrates a coordinated metabolic response through modulation of key nutrient sensing pathway such as AMP activated protein kinase (AMPK), mechanistic target of rapamycin (mTOR) and unc-51-like kinase 1 (ULK1). These cascades interact with Sirtuins (SIRT1/3), peroxisome proliferator activated receptor gamma coactivator-1\u03b1 (PGC-1\u03b1) and the transcription factor EB (TFEB) to regulate autophagy, mitochondrial biogenesis, oxidative stress defense and cellular repair.

No definitive methods exist to repair damaged neurons. Vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) are two neuroprotective agents that work synergistically. However, these large molecular proteins have difficulty crossing the blood-brain barrier (BBB). Extracellular vesicles (EVs) offer superior targeting and low immunogenicity, making them excellent carriers. In this study we examined the protective effects of VEGF and NGF in a cell model and evaluated the therapeutic potential of VEGF-NGF contained within EVs in PD rats. EVs were isolated using sequential differential centrifugation and characterized using transmission electron microscopy, nanoparticle tracking analysis, and western blotting (WB). VEGF and NGF were loaded into the EVs using a saponin-assisted method to create VEGF@EVs, NGF@EVs, and VEGF/NGF@EVs. The viability of 6-hydroxydopamine hydrochloride (6-OHDA)-induced SH-SY5Y cells was measured using the cell counting kit-8 assay before and after treatment with VEGF and NGF. Autophagy levels were assessed using WB, and the role of autophagy was further explored using the autophagy inhibitor chloroquine. Unilateral PD rat models were established via stereotactic injection of 6-OHDA into male Sprague-Dawley rats. Behavioral changes were monitored before and after treatment. Neuronal recovery, neurotransmitter levels, and autophagy levels in the rat brains were evaluated using immunohistochemistry, enzyme-linked immunosorbent assay, and WB. VEGF/NGF@EVs significantly enhanced the viability of 6-OHDA-induced SH-SY5Y cells. A complete autophagic process was identified as essential for this protective effect. The intranasal administration of VEGF/NGF@EVs improved motor behavior in PD rats, with performance better than that of single growth factor treatments. The number of tyrosine hydroxylase (TH)-positive neurons, TH protein expression, and dopamine content were significantly increased. In addition, the level of autophagy in the rat substantia nigra was elevated. VEGF/NGF@EVs exert protective effects in both in vitro and in vivo 6-OHDA-induced PD models by promoting autophagy, demonstrating greater efficacy than either growth factor alone. By transplanting VEGF/NGF@EVs into PD rats, we showed that these vesicles can effectively cross the BBB and deliver targeted therapy to the central nervous system. This study highlights the significant potential of EV-mediated protein transplantation strategies for treating neurological disorders."

Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities."

Among those, the short isoform of Nuclear Receptor Coactivator 7 (NCOA7-AS) has been shown to inhibit IAV entry and more especially the fusion between endosomal and viral membranes. Ectopic expression of NCOA7-AS leads to the increased acidification of the endolysosomal pathway, putatively through NCOA7-AS interaction with the vacuolar ATPase (V-ATPase). However, the precise mechanism of action of NCOA7-AS is not fully understood. Here, we identified the cellular partners of NCOA7-AS by mass spectrometry, including the V-ATPase subunits known to interact with NCOA7-AS. A point mutation disrupting the interaction with the V-ATPase led to loss of antiviral activity against IAV, demonstrating that V-ATPase engagement is required for the antiviral phenotype. Moreover, sorting nexin (SNX) 1/2/5/6 were identified as novel partners of NCOA7-AS. These proteins are involved in retrograde transport of cellular cargoes from endosomes to the trans-Golgi network. We revealed that SNX5/6 interacted directly with NCOA7-AS and were essential for NCOA7-AS antiviral activity against IAV. Interestingly, crystal structures of NCOA7-AS/SNX5 complexes showed that the SNX5-interaction motif in NCOA7-AS was similar to those found in known cargoes of SNX5/6. In addition, we could pinpoint several critical residues that were important for binding and antiviral activity. Collectively, our study identifies novel essential partners for NCOA7-AS antiviral activity and the structural basis for their interaction."

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."

Moreover, we discuss the potential role of TMEM106B as an important modifier of the protein TDP-43 neuropathology associated with the GRN mutation in this case. The patient underwent detailed clinical assessment, serial neuropsychological evaluation, brain MRI, cerebrospinal fluid analysis, whole-exome sequencing, and next generation sequencing. A postmortem neuropathologic examination was performed to confirm the diagnosis. The patient presented slowly progressive paresthesia, cerebellar ataxia, dysarthria, and later cognitive and behavioral changes. Genetic testing revealed a heterozygous PRNP P102L variant and an unpenetrated GRN p.R110X variant; a protective TMEM106B polymorphism associated with TDP-43 pathology was also identified. Neuroimaging demonstrated progressive cerebellar and parietal atrophy with asymmetric left frontal opercular and insular involvement. The clinical course was dominated by a cerebellar GSS phenotype. The patient died 4 years after symptom onset. Neuropathology confirmed GSS, nevertheless without detectable TDP-43-associated neuropathology. This case highlights the diagnostic complexity of rare neurodegenerative disorders and illustrates that pathogenic variants may not influence phenotypic expression. Comprehensive genetic testing should be considered in atypical cases, as certain genetic variants may contribute to phenotypic variability and represent potential modifiers of phenotypic expression."

Here, we investigate whether the CT Receptor plays a role in cancer cell survival. In cancer cell lines, knockdown of CALCR disrupts the cell cycle and induces apoptosis, supporting an essential pro-survival role. The CALCR gene produces three main transcripts in humans, of which Transcript 1 encodes CALCRb mRNA including exon 10 and is translated into the CTb Receptor isoform, and Transcripts 2 and 3 which are translated into the CTa Receptor. CALCRb expression is conserved across a diverse range of mammalian species. We examined the expression of all CT Receptor isoforms (CALCRtotal) and CALCRb expression in four high-grade glioma stem-like cell lines and in U-87 MG glioblastoma cells. Using qPCR, we observed stable levels of both CALCRtotal and CALCRb expression under conditions of autophagy or apoptosis, consistent with a requirement for CALCRb in cell survival. As alternative splicing (AS) of key genes in cancers confers tumour resilience, we investigated AS of CALCR transcript 2 using long-read nanopore sequencing. Unexpectedly, we discovered a novel AS event causing inclusion of exon 10 within Transcript 2 in all glioblastoma cell lines investigated. This finding, together with stable CALCRb expression under cellular stress and the finding by other groups confirming that knockdown of CT Receptor compromises cell survival, implicates the CTb Receptor as a potential oncoprotein."

Circular RNAs (circRNAs), characterized by their covalently bonded single-stranded loop configuration, have been identified as functional regulators across various cancer types. Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression."

MicroRNAs (miRNAs), which are critical post-transcriptional regulators, have emerged as important modulators of animal behavior. This study investigated the molecular basis of aggression in pigs ( Sus scrofa), focusing on miRNA-mediated regulation. Hypothalamic miRNA-sequencing of the most aggressive ( n=4) and least aggressive ( n=4) piglets identified nine differentially expressed miRNAs. Among these, miR-27a was significantly upregulated in aggressive individuals. Functional assays demonstrated that both porcine miR-27a and its human ( Homo sapiens) ortholog has-miR-27a-3p, suppressed autophagy, apoptosis, and neuronal plasticity in primary porcine neurons and human SH-SY5Y neuroblastoma cells. To clarify the underlying mechanisms, mRNA-sequencing was performed on porcine neurons transfected with miR-27a mimics or negative controls, identifying 436 differentially expressed genes (84 upregulated and 352 downregulated). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses highlighted eight genes- CBL, PRKCA, SLC38A1, ZBTB16, AANAT, CYP1A1, SLC7A11, and NTRK2-associated with tryptophan metabolism, oxidative stress, and long-term synaptic depression. Bioinformatic analysis and dual-luciferase reporter assays confirmed that miR-27a directly targets the 3'-UTR of PRKCA, thereby suppressing of autophagy, apoptosis, and neuronal plasticity. In vivo, intrahypothalamic injection of mmu-miR-27a-3p in mice ( Mus musculus) reduced motor function and social dominance, and placed the mice at a competitive disadvantage, while supressing neuronal autophagy, apoptosis and plasticity. \u968f\u7740\u96c6\u7ea6\u5316\u52a8\u7269\u751f\u4ea7\u7684\u666e\u53ca\uff0c\u4eba\u4eec\u5bf9\u52a8\u7269\u798f\u5229\u7684\u5173\u6ce8\u65e5\u76ca\u589e\u52a0\u3002\u653b\u51fb\u884c\u4e3a\u4f5c\u4e3a\u5f71\u54cd\u52a8\u7269\u798f\u5229\u7684\u91cd\u8981\u56e0\u7d20\uff0c\u5bf9\u63d0\u5347\u798f\u5229\u6c34\u5e73\u548c\u751f\u4ea7\u6548\u7387\u81f3\u5173\u91cd\u8981\u3002\u800c\u4f5c\u4e3a\u8f6c\u5f55\u540e\u8c03\u63a7\u7684\u5173\u952e\u5206\u5b50miRNA\u5df2\u6210\u4e3a\u52a8\u7269\u884c\u4e3a\u7684\u91cd\u8981\u8c03\u8282\u56e0\u5b50\u3002\u8be5\u7814\u7a76\u65e8\u5728\u4ece\u5206\u5b50\u5c42\u9762\u89e3\u6790\u732a\u653b\u51fb\u884c\u4e3a\u7684\u5f62\u6210\u673a\u5236\uff0c\u91cd\u70b9\u5173\u6ce8 miRNA \u4ecb\u5bfc\u7684\u8c03\u63a7\u4f5c\u7528\u3002\u901a\u8fc7\u5bf9\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\uff08 n = 4\uff09\u548c\u8f83\u5f31\uff08 n = 4\uff09\u4ed4\u732a\u4e0b\u4e18\u8111\u8fdb\u884c miRNA \u6d4b\u5e8f\uff0c\u5171\u9274\u5b9a\u51fa 9 \u79cd\u5dee\u5f02\u8868\u8fbe\u7684 miRNA\u3002\u5176\u4e2d\uff0cmiR-27a \u5728\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\u7684\u4e2a\u4f53\u4e2d\u663e\u8457\u4e0a\u8c03\u3002\u7ec6\u80de\u529f\u80fd\u5b66\u9a8c\u8bc1\u8868\u660e\uff0cssc-miR-27a \u53ca\u5176hsa-miR-27a-3p \u80fd\u591f\u6291\u5236\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u548c\u4eba\u795e\u7ecf\u6bcd\u7ec6\u80de\u7624\u7ec6\u80de\u7cfb\uff08SH-SY5Y\uff09 \u7684\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002\u4e3a\u4e86\u8fdb\u4e00\u6b65\u63a2\u7a76 miR-27a \u5bf9\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u7684\u8c03\u63a7\u4f5c\u7528\uff0c\u901a\u8fc7\u5bf9\u8f6c\u67d3 miR-27a \u6a21\u62df\u7269\u548c\u9634\u6027\u5bf9\u7167\u7684\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u8fdb\u884c mRNA-seq\uff0c\u5171\u9274\u5b9a\u51fa 436 \u4e2a\u5dee\u5f02\u8868\u8fbe\u57fa\u56e0\uff0884 \u4e2a\u4e0a\u8c03\uff0c352 \u4e2a\u4e0b\u8c03\uff09\u3002\u5bcc\u96c6\u5206\u6790\uff08GO\u3001KEGG\u3001PPI\uff09\u53d1\u73b0\u67098\u4e2a\u57fa\u56e0\u2014\u2014 CBL\u3001 PRKCA\u3001 SLC38A1\u3001 ZBTB16\u3001 AANAT\u3001 CYP1A1\u3001 SLC7A11 \u548c NTRK2\uff0c\u4e0e\u8272\u6c28\u9178\u4ee3\u8c22\u3001\u6c27\u5316\u5e94\u6fc0\u548c\u957f\u671f\u7a81\u89e6\u6291\u5236\u7b49\u901a\u8def\u76f8\u5173\u3002\u751f\u7269\u4fe1\u606f\u5b66\u548c\u53cc\u8367\u5149\u7d20\u9176\u62a5\u544a\u57fa\u56e0\u68c0\u6d4b\u8868\u660e\uff0cmiR-27a \u76f4\u63a5\u9776\u5411 PRKCA \u7684 3'-UTR\uff0c\u4ecb\u5bfc\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u7684\u6291\u5236\u3002\u6d3b\u4f53\u5b9e\u9a8c\u8868\u660e\uff0c\u5c0f\u9f20\u4e0b\u4e18\u8111\u5185\u6ce8\u5c04 mmu-miR-27a-3p \u4f1a\u964d\u4f4e\u5176\u8fd0\u52a8\u529f\u80fd\uff0c\u524a\u5f31\u5176\u793e\u4f1a\u652f\u914d\u5730\u4f4d\uff0c\u5e76\u4f7f\u5176\u5904\u4e8e\u7ade\u4e89\u52a3\u52bf\uff0c\u540c\u65f6\u6291\u5236\u5c0f\u9f20\u795e\u7ecf\u5143\u7684\u81ea\u566c\u3001\u7ec6\u80de\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002."

Despite advances in antiseizure medications, effective epilepsy management remains challenging because of pharmacoresistance, limited blood-brain barrier (BBB) permeability, inadequate intracerebral drug accumulation, and systemic toxicity. Moreover, currently available therapies primarily provide symptomatic seizure control without addressing the fundamental pathological processes involved in epileptogenesis, neuroinflammation, oxidative stress, and neuronal degeneration. Intranasal administration has emerged as an attractive non-invasive approach for direct brain targeting, enabling therapeutic agents to circumvent BBB-associated transport barriers and access the central nervous system through the olfactory and trigeminal neural pathways. In this context, biodegradable nanomedicine platforms have gained considerable attention due to their favorable biocompatibility, controlled drug release, enhanced mucosal permeation, and potential for targeted intracerebral delivery. This review provides a comprehensive and critical overview of recent advances in intranasal biodegradable nanomedicine for epilepsy, integrating current knowledge on disease pathophysiology, biological and pharmaceutical barriers, nose-to-brain transport mechanisms, biodegradable nanoparticle platforms, and emerging functionalization strategies. Importantly, the review critically evaluates the current evidence, distinguishing encouraging preclinical findings and discusses the major translational challenges that continue to hinder clinical implementation. Finally, future perspectives are highlighted to identify opportunities for developing safer, more effective, and clinically translatable therapies for epilepsy management."

However, accumulating evidence over the past several decades has established them as the three principal endogenous gasotransmitters that regulate a wide spectrum of physiological and pathological processes. Unlike conventional signaling molecules, gasotransmitters diffuse freely across biological membranes and exert potent biological effects through receptor-independent mechanisms, including redox-sensitive post-translational modifications and modulation of heme-containing proteins. Although the individual functions of NO, CO, and H2S have been extensively reviewed, emerging studies indicate that these gaseous mediators rarely operate in isolation. Instead, they form a highly integrated signaling network characterized by direct chemical interactions, reciprocal enzymatic regulation, and convergence upon common downstream pathways. In this mini-review, we propose the concept of a \"Gasotransmitter Trio Network,\" emphasizing the molecular crosstalk among NO, CO, and H2S as a fundamental determinant of cellular homeostasis. We first summarize the biosynthetic pathways and major signaling mechanisms of the gasotransmitter trio, including S-nitrosylation, persulfidation, and heme-dependent regulation. We then discuss recent advances revealing how interactions among these gases generate novel bioactive intermediates and coordinate redox signaling. Particular attention is given to the emerging roles of gasotransmitters in regulating ferroptosis, autophagy, and mitophagy by modulating iron metabolism, lipid peroxidation, mitochondrial quality control, and antioxidant defense systems. These findings support a unified framework in which gasotransmitters function as master regulators of cellular fate under conditions of physiological and pathological stress. Finally, we highlight recent progress in stimuli-responsive donors, CO-releasing molecules (CORMs), NO-releasing materials (NORMs), H2S donors, and advanced nanoplatforms that enable spatiotemporally controlled gas delivery. We propose that future therapeutic strategies will increasingly rely on programmable multi-gas systems that recapitulate endogenous gasotransmitter networks. Collectively, this review provides a systems-level perspective on gasotransmitter biology and outlines emerging opportunities for the development of precision gas medicine in cardiovascular, neurodegenerative, inflammatory, metabolic, and malignant diseases."

Shikonin, a natural anti-tumor compound, exerts anti-BCa activity, yet its direct molecular target and underlying mechanism remain undefined. This study aimed to identify the direct target of shikonin in BCa and to elucidate the mechanism by which shikonin suppresses tumor progression. The anti-BCa effects of shikonin were assessed in vitro and in vivo. Drug affinity responsive target stability (DARTS) combined with 4D quantitative proteomics identified shikonin's direct target, which was validated by molecular docking and cellular thermal shift assay (CETSA). Gain- and loss-of-function experiments and ER-phagy-related assays elucidated the underlying molecular mechanism. Shikonin inhibited BCa cell proliferation, migration, invasion and induced senescence in vitro, and suppressed tumor growth in vivo with no obvious toxicity. Deoxyribonuclease 2 (DNASE2) was identified as shikonin's direct target; shikonin promoted DNASE2 ubiquitination and degradation without altering its mRNA level. DNASE2 was highly expressed in BCa and correlated with poor prognosis, and its knockdown mimicked and enhanced shikonin's anti-BCa effects. Mechanistically, shikonin targeted DNASE2 to downregulate Reticulon 3 (RTN3), thereby inhibiting RTN3-dependent endoplasmic reticulum autophagy (ER-phagy) in BCa. This study first identifies DNASE2 as the direct target of shikonin in BCa, and reveals that shikonin exerts anti-BCa activity by promoting DNASE2 ubiquitination/degradation to inhibit the DNASE2/RTN3 axis-mediated ER-phagy. The DNASE2/RTN3 axis is a novel ER-phagy regulatory node in BCa, providing a potential therapeutic target for BCa treatment."

How the predicted regulatory potential of these miRNAs differs among the milks of different animals most relevant to human nutrition has not been systematically compared. Here, we performed an integrative in silico analysis of publicly available small-RNA sequencing data from 29 milk and milk-cell samples of human, cow, goat, and donkey origin. miRNAs were quantified against human (hsa) miRBase references-thereby restricting the analysis to evolutionarily conserved miRNAs with human orthologs-and their predicted effect on the human transcriptome was modeled by integrating predicted (mirDIP database) and experimentally supported (TarBase v9 database) miRNA-target interactions into a per-gene, per-species weighted targeting score. Because miRNAs act predominantly as repressors, this score is read as a prediction of which genes would be post-transcriptionally down-regulated in a recipient. miR-148a-3p dominated the exosomal spectrum of all four species (human, cow, goat, and donkey; \u224821.5% of pooled abundance), and the twenty most abundant miRNAs accounted for roughly three quarters of the signal. Of 4577 robustly targeted genes, a 1809-gene conserved \"pan-milk\" core showed the highest cross-species targeting and was enriched for transcriptional regulation, PI3K-Akt, MAPK, and TGF-\u03b2/SMAD signaling, autophagy and-strikingly-the components of the RNA-interference machinery itself. Species-restricted gene sets recapitulated biologically plausible programs, including a human-biased neuronal/axon-guidance and chromatin module, a donkey-biased transcriptional, epithelial, and immune (CD47) module, and a ruminant lipid/cholesterol and insulin-mTOR module. Across categories, we observed a reproducible confidence-exclusivity trade-off. We emphasize that these results are computational predictions that assume dietary miRNA uptake and do not constitute experimental validation. We provide the complete targetome as a hypothesis-generating resource to prioritize candidate genes, pathways, and milk types for future functional, nutritional, and epigenetic investigation. Across the 29 samples from the four species, miRNA composition segregated by species (silhouette width = 0.82, a cluster-separation measure ranging from -1 to 1, with values near 1 indicating well-separated groups) and the category structure exceeded a permutation null, indicating that the between-species signal is robust to differences in dataset origin and milk state."

On the other hand, excessive and prolonged ER stress leads to apoptosis. However, the relationships between different UPR branches and apoptosis or autophagy vary in cancer cells of different origins and depend on the extent and nature of the stress signal. This study was designed to establish the role of ER stress sensors protein kinase RNA-like endoplasmic reticulum kinase (PERK) and inositol-requiring enzyme 1 (IRE1\u03b1) in apoptosis or autophagy signaling in T-lymphoblastic leukemia MOLT-3 cells via the RNA interference method. The cells were transfected with small interfering RNAs (si-PERK, si-IRE1\u03b1, or si-Cont) for 6 h and further cultured under normal conditions for 72 h to provide an insight into chronic effects of the gene silencing. The expression of apoptosis and autophagy effectors at the mRNA and protein levels was compared using RT-PCR and Western blot assays, respectively. Transfection of the cells with PERK siRNA led to a significant decrease in PERK protein and gene expression, and decreased phosphorylation of its downstream effector eukaryotic initiation factor 2\u03b1 (eIF2\u03b1). PERK silencing was accompanied by activation of apoptosis-related genes and proteins-BCL2-associated X (Bax), caspase-3, C/EBP homologous protein (CHOP), while the levels of autophagy markers (Unc-51 like autophagy activating kinase 1 (ULK1), Beclin-1, and microtubule-associated proteins 1A/1B light chain 3 (LC3A/B)) remained stable. In contrast, treatment of the cells with si-IRE1\u03b1 reduced the content of IRE1\u03b1, X-box-binding protein 1 (sXBP1), and glucose-regulated protein 78 (GRP78) proteins, but increased ERN1 gene expression. IRE1\u03b1 RNA interference did not affect the levels of the pro-apoptotic marker Bax, but suppressed caspase-3, CHOP, c-Jun N-terminal kinase (JNK), and autophagy signaling molecules (ULK1, Beclin-1, LC3A/B) at both the transcriptional and translational levels. These results indicate that the PERK pathway is an important contributor to the survival of MOLT-3 cells under basal ER stress, while PERK depletion compromises the resistance of cells to UPR-mediated apoptosis. The IRE1\u03b1 UPR branch is directly linked with autophagy-dependent signaling, although IRE1\u03b1 knockdown exerted a more complicated influence on the cells, probably via activation of multiple pro-death and compensatory pro-survival regulatory mechanisms."

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]\nHypothesis: Intranasal delivery of Spermidine-modified Ginseng Extracellular Vesicles (S-GEVs) loaded with GRN mRNA exploits the cribriform plate anatomy to bypass the blood-brain barrier, providing a neuro-targeted delivery system for progranulin gene therapy that acts synergistically with spermidine-induced autophagy to suppress pathological TMEM106B amyloid accumulation and restore endolysosomal homeostasis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe proposed hypothesis posits that a composite nanotherapeutic consisting of ginseng-derived extracellular vesicles (GEVs) functionalized with spermidine and loaded with *GRN* mRNA could ameliorate neurodegenerative conditions characterized by *GRN* haploinsufficiency and TMEM106B protein aggregation. The conceptual framework relies on three intersecting domains: (1) nasal-to-brain delivery mechanisms circumventing the blood-brain barrier (BBB), (2) the intrinsic neuroprotective and autophagy-inducing properties of spermidine, and (3) the endolysosomal roles of PGRN and TMEM106B. While the evidence validates these individual components, the specific synergy of an S-GEV/GRN mRNA delivery system remains a novel, untested computational framework.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent evidence confirms that the blood-brain barrier (BBB) presents a formidable obstacle to neurotherapeutics, with \"over 98% of small-molecule drugs and nearly all biologics fail to cross this barrier.\" Intranasal delivery offers a non-invasive bypass, as identified by the presence of \"a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations\" which facilitate drainage to the cervical lymph nodes. Ginseng-derived exosomes have been characterized as \"natural nanovesicles\" offering \"large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers.\" \n\nRegarding the therapeutic cargo, *GRN* mutations and TMEM106B aggregation are central to neurodegeneration, as \"The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases.\" Furthermore, \"Recent new studies reported that TMEM106B proteins form intracellular amyloid filaments which universally exist in various neurodegenerative diseases, sometimes being the dominant form of protein aggregation.\" Restoration of progranulin is hypothesized to alleviate lysosomal dysfunction. Concurrent induction of autophagy is essential, as \"Spermidine, a naturally occurring polyamine, has emerged as a candidate modulator of brain aging because it regulates autophagy, mitochondrial function, oxidative balance, and neuroinflammatory signaling.\" The integration of these elements into a single S-GEV platform represents a sophisticated, if currently unverified, therapeutic modality.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* TMEM106B aggregation is not merely a loss-of-function event but involves the formation of universal intracellular amyloid filaments across multiple neurodegenerative diseases.\n* Nasal delivery routes, specifically through arachnoid fenestrations at the olfactory bulb, are increasingly recognized as viable channels for protein and nucleic acid transport.\n* Ginseng-derived exosomes are effectively serving as \"natural nanocarriers\" capable of cross-kingdom delivery of metabolites and therapeutics.\n* Spermidine's efficacy as a neuroprotector is dosage-dependent, where \"low doses has the potential to be a general-purpose neuroprotector.\"\n* Autophagic flux, regulated by proteins such as Beclin-1 and the mTOR/AMPK axis, is a critical regulatory node for both progranulin and TMEM106B-associated pathologies.\n* The TMEM106B/progranulin endolysosomal-lipid axis is essential for metabolic homeostasis; its disruption leads to protein accumulation.\n* Emerging \"Gasotransmitter Trio Networks\" (NO, CO, H2S) modulate autophagy and mitophagy alongside the protein-based pathways of *GRN* and TMEM106B.\n* Recent proteomics studies confirm that CLK4 regulates autophagy-related proteins (e.g., SQSTM1) in cancer and degenerative models, highlighting broader splicing/autophagy interactions.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Over 98% of small-molecule drugs and nearly all biologics fail to cross this barrier. Nanoparticles (NPs) provide multiple ways to bypass the BBB. These include receptor-mediated transcytosis, adsorptive-mediated transport, and intranasal delivery. NPs can also modify disease-related pathways. For example, they promote amyloid-\u03b2 clearance, reduce tau phosphorylation, and reprogram neuroimmune responses. Many preclinical studies have shown promising results in Alzheimer's, Parkinson's, and Huntington's diseases. However, no NP-based therapy has moved beyond early-stage clinical trials. Several issues remain unresolved. Direct comparisons between different NP platforms are lacking. The long-term toxicity of NPs in the brain is not well understood. Animal models also do not accurately reflect human disease. We suggest that future work should focus on standardized characterization, better predictive models, and clinical trial designs that address NP diversity. Researchers should also compare NP therapies with existing treatments in a rigorous manner."

However, concerns exist regarding potential toxicity and cost-effectiveness, limiting their clinical applications. In contrast, plant-derived exosomes (PDEs), as natural nanovesicles, offer significant advantages as drug delivery carriers due to their large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers. In this work, we established a ginseng-derived exosome (G-Exo)-based CDDP delivery system (G-CDDP) and evaluated its anti-tumor efficacy both in vitro and in vivo. The results demonstrated that G-CDDP effectively targeted tumor site, inhibiting the proliferation and migration and promoting apoptosis in U-87MG tumor cells. Notably, the amount of CDDP in G-CDDP required for achieving the same cytotoxic effect on tumor cells was 12.66 times lower than that of free CDDP. In U-87MG tumor-bearing mice, G-CDDP effectively targeted tumor sites and exhibited significant therapeutic effect. Collectively, these findings highlight the potent anti-tumor activity of G-CDDP at reduced CDDP dosage, positioning it as a promising and efficient alternative to conventional drug treatments in clinical settings."

Using a multifaceted approach in mice, we examined tracer dynamics and the CSF outflow pathway from the subarachnoid space (SAS) to the nasal mucosa and identified a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations. Similar arachnoid fenestrations were found in cynomolgus monkeys. Fluorescent tracers in the SAS passed through arachnoid fenestrations into dural lymphatics, which traversed the cribriform plate foramina, joined the nasal lymphatics, and drained to the cervical lymph nodes. In aged mice, the known reduction in CSF outflow was accompanied by lymphatic atrophy in the olfactory dura and nasal mucosa and by fewer arachnoid fenestrations and smaller cribriform plate foramina. Importantly, the lymphatics and CSF clearance were restored to normal by intranasal delivery of vascular endothelial growth factor-C (VEGF-C), thereby documenting the reversibility of the aging-related impairment in CSF clearance."

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations."

Despite this commonality, most current therapeutic approaches in the field, such as anti-aggregate antibodies, are focused on individual diseases or single neuropathologies with only limited success. The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases. Thus, these proteins are predicted to participate in common pathogenic pathways shared across various neurodegenerative diseases. Importantly, recent discoveries of TMEM106B amyloid fibrils in varied neurodegenerative diseases and glycosphingolipid regulation by progranulin and TMEM106B further support their central roles in cross-disease neurodegenerative mechanisms. This review summarizes recent advances in progranulin and TMEM106B function within the endolysosomal system and neurodegenerative diseases. It describes preclinical models and therapeutic approaches for progranulin- and TMEM106B-associated diseases. We also discuss future direction leading to novel alternative therapies targeting shared mechanisms in neurodegenerative diseases."

"abstract_text": "ID: 42541426\nTitle: Neuroprotective Potential of Spermidine in Drosophila sws Neurodegenerative Model.\nAbstract: Neurodegenerative disorders are characterized by progressive neuronal loss and functional decline, yet effective interventions remain limited. The polyamine spermidine was suggested to exert neuroprotective effects, but its concentration-dependent impact on longevity, neuronal integrity, and behavior remains still not well studied. Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC). Our results suggest that spermidine at low doses has the potential to be a general-purpose neuroprotector."

Nasal administration has emerged as a promising non-invasive route, bypassing the BBB via direct neural pathways (olfactory/trigeminal), systemic absorption, or lymphatic drainage. However, inherent nasal barriers like the mucus layer and epithelium limit its efficacy. This review distinguishes itself by integrating mechanistic insights into nasal transport pathways with the rational design of advanced nano-delivery systems. We first outline the challenges in CNS drug delivery and detail the nasal anatomy and transport pathways facilitating nose-to-brain delivery. Subsequently, we emphasize the critical properties required of advanced nano-carriers to improve mucosal penetration, prolong retention, and promote drug accumulation at cerebral injury sites. Following a detailed analysis of the advantages and limitations associated with nose-to-brain delivery, we consolidate recent advances in nasal nano-delivery systems for treating CNS disorders, emphasizing their capacity to improve brain-targeting efficiency, enhance therapeutic efficacy, reduce systemic toxicity, and enable previously undruggable CNS targets. Finally, we expand the discussion to encompass current challenges impeding clinical translation, including safety concerns, manufacturing scalability, and regulatory hurdles, while highlighting emerging trends such as artificial intelligence-driven formulation design. This comprehensive analysis aims to deepen the understanding of nasal-to-brain transport mechanisms and inform the future development of effective nasal formulations for improved neurological therapeutics."

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity."

While cobalt ions are linked to neurodegenerative diseases, the neurodevelopmental toxicity of Co3O4 NPs remains poorly understood. Ferroptosis, a process regulated by iron homeostasis, can be triggered by ferrous overload through ferritinophagy. This study explores how Co3O4 NPs induce ferritinophagy and their role in neurodevelopmental toxicity. Zebrafish larvae exposed to Co3O4 NPs at concentrations of 0, 5, and 50\u202fmg/L for up to 120\u202fh post-fertilization (hpf) exhibited dose-dependent developmental toxicity, including delayed hatching, increased malformations, and impaired motor behavior. Transgenic zebrafish models demonstrated neuronal shortening, reduced fluorescence, and altered neurotransmitter profiles, as supported by liquid chromatography-tandem mass spectrometry. Co3O4 NPs induced oxidative stress, leading to iron overload, lipid peroxidation (elevated MDA, depleted glutathione), and ferritinophagy activation, as evidenced by changes in genes and proteins related to iron metabolism (trf, fpn, slc7a11) and ferroptosis (GPX4, ACSL4, FTH1, NCOA4). Ferritinophagy was further confirmed using autophagy inhibitors, demonstrating its role in neurotoxicity. Additionally, Vitamin E (d-\u03b1-tocopherol), a lipid-soluble antioxidant that suppresses lipid peroxidation, reduced neurodevelopmental abnormalities, supporting that Co3O4 NP-induced toxicity occurs through ferritinophagy-mediated ferroptosis, leading to neurotransmitter dysregulation. These findings were corroborated in human neuroblastoma cells (SH-SY5Y/SK-N-SH). In conclusion, Co3O4 NPs disrupt iron homeostasis, activate ferritinophagy, and induce ferroptosis, resulting in neurotransmitter dysregulation and neurodevelopmental toxicity. These results provide new insights for assessing the neurodevelopmental toxicity and environmental risk of Co3O4 NPs and similar nanomaterials."

A pivotal feature of PD pathogenesis is the dual role of microglia, which shifts from maintaining neuronal homeostasis to driving neuroinflammation and neurodegeneration. The mechanisms underlying this functional transition and its consequences for disease progression require a comprehensive synthesis. A structured PubMed search was performed using the keywords \"Parkinson's disease\", \"microglia\", \"neuroinflammation\", \"\u03b1-synuclein\", \"polarization\", \"tunneling nanotubes (TNTs)\", \"NF-\u03baB\", and \"NLRP3\". Relevant combinations of these terms were also used. A total of 2952 records were retrieved up to December 2025. Of these, 147 studies were included based on relevance to microglial polarization, neuroinflammation, \u03b1-syn-related pathology, and intercellular communication mechanisms. In early PD stages, microglia exert neuroprotective effects by transferring excess neuronal \u03b1-syn via TNTs, delivering healthy mitochondria, and clearing \u03b1-syn through autophagy. With disease progression, accumulated \u03b1-syn promotes microglial polarization toward the M1 phenotype. This shift activates TLR2/4, TREM2, MHCII, and RAGE receptors, triggering NF-\u03baB/NLRP3 pathways, releasing pro-inflammatory cytokines, and generating NOX2-derived ROS. The resulting neuroinflammatory cascade not only damages dopaminergic neurons directly but also disrupts astrocyte function and blood-brain barrier integrity, creating a self-perpetuating cycle of inflammation and neurodegeneration. These findings support dysregulated microglial polarization as an important component of PD pathobiology, but the available evidence remains weighted toward preclinical models. Future work should better define the timing, heterogeneity, and clinical measurability of microglial state transitions before microglia-targeted strategies can be translated with confidence. Microglial polarization may represent a potential therapeutic direction in Parkinson's disease, although further mechanistic and clinical validation and more precise biomarker definition remain necessary."

Dysregulation of these processes is implicated in numerous diseases, including cancer, liver disorders, and neurodegenerative diseases. p62/Sequestosome 1 (SQSTM1) is a multifunctional protein that plays a central role in protein homeostasis and stress responses by regulating autophagy and signal transduction pathways. Through its multiple protein-interacting domains, p62 functions both as a scaffold for selective autophagic degradation and as a signaling hub. Since our previous review of p62 a decade ago, substantial progress has been made in elucidating its molecular functions and physiological roles. Notably, p62 undergoes liquid-liquid phase separation with ubiquitinated proteins to form membraneless condensates, termed p62 bodies, when cells are exposed to proteotoxic stress. By sequestering specific proteins, p62 bodies act as platforms for autophagy-dependent degradation and stress signaling. These findings have substantially revised our view of p62 function, which was previously considered primarily as a receptor simply linking ubiquitinated substrates to autophagic membranes and connecting signaling molecules. This conceptual shift from one-to-one molecular interactions to multivalent, multimolecular, higher-order assemblies has fundamentally redefined the functional landscape of p62. In this review, we highlight how p62 bodies integrate selective autophagy and stress signaling, with a particular emphasis on their emerging roles in disease pathogenesis and their potential as therapeutic targets."

Although \u03b1-syn aggregation is considered central to PD pathogenesis, increasing evidence suggests that \u03b1-syn abundance may be as important as its conformational state. Genetic studies have demonstrated an SNCA dosage effect, with gene duplication and triplication associated with progressively more severe familial PD phenotypes. Complementary evidence indicates that dysfunction of protein clearance pathways, particularly the autophagy-lysosome system, promotes intracellular \u03b1-syn accumulation and increases its neurotoxic potential. In this review, we propose \u03b1-syn multiplication as an integrative framework for interpreting PD pathogenesis. This concept extends beyond SNCA copy-number variation to encompass processes that increase the effective \u03b1-syn burden within neurons or across neural networks, including increased gene expression, impaired degradation, disrupted proteostasis, and pathological propagation. We summarize \u03b1-syn structural dynamics and the concentration-dependent distribution of monomeric, oligomeric, and fibrillar species. We then review evidence from SNCA gene-dosage studies and examine the role of the autophagy-lysosome pathway in regulating \u03b1-syn homeostasis, with particular emphasis on recent experimental findings demonstrating that autophagy deficiency exacerbates \u03b1-syn accumulation and neurodegeneration in human \u03b1-syn bacterial artificial chromosome transgenic mice. Collectively, the available genetic, biochemical, and experimental evidence supports a model in which the balance between \u03b1-syn production and clearance influences disease progression alongside protein misfolding. The interaction between increased protein burden and impaired clearance capacity provides a unifying mechanism linking familial and sporadic forms of PD. We propose that \u03b1-syn multiplication offers an integrative framework for understanding PD pathogenesis, provides a quantitative perspective on disease heterogeneity, and highlights therapeutic opportunities aimed at reducing \u03b1-syn burden and restoring proteostatic balance."

In this study, circular RNA circAP2B1 is identified as a critical regulatory molecule that is markedly upregulated in ESCC tissues and patient serum and strongly associated with poor prognosis. Mechanistically, tumor-derived exosomes efficiently deliver circAP2B1 to tumor-associated macrophages (TAMs), where it serves as a distinct molecular scaffold that simultaneously binds the transcription factor ESRRA and the nuclear import receptor KPNA1, facilitating ternary complex formation and ESRRA nuclear translocation. Once in the nucleus, ESRRA directly activates the transcription of Mitofusin 2 (MFN2), a pivotal regulator of mitochondrial fusion, thereby enhancing mitochondrial oxidative phosphorylation, improving ATP production efficiency, and establishing a metabolically optimized intracellular environment that ultimately drives TAMs toward a pro-tumor M2 phenotype. Both in vitro and in vivo experiments demonstrate that targeted intervention of the circAP2B1/ESRRA/KPNA1/MFN2 signaling axis effectively reverses M2 polarization and markedly suppresses tumor progression. This study uncovers a novel exosomal circRNA-mediated metabolic-immune regulatory pathway and offers new avenues for the diagnosis and treatment of ESCC. The findings not only expand the understanding of circRNA functions in tumor immunity but also provide a theoretical basis for the development of therapies targeting the metabolic-immune axis."

Exosomes derived from adipose-derived mesenchymal stem cells (ADMSC-Exo) have robust protective effects under non-otologic ischemic conditions. However, their otoprotective effects remain unclear. This study aimed to investigate the protective effects of human ADMSC-Exo against cochlear damage and mitochondrial dysfunction under oxygen-glucose deprivation (OGD), an in vitro and ex vivo model of cochlear ischemia. ADMSC-Exo attenuated OGD-induced cytotoxicity and apoptosis in HEI-OC1 cells and reduced the OGD-induced loss of cochlear hair cells in the organ of Corti explants. OGD caused a decrease in mitochondrial mass and mitochondrial membrane potential depolarization and impaired mitochondrial respiration in auditory cells. ADMSC-Exo preserved mitochondrial integrity and improved mitochondrial bioenergetic function following OGD exposure. These effects were accompanied by increased LC3-II conversion and formation of autolysosome-like structures and elevated expression of PINK1 and Parkin, indicating the activation of autophagy and mitophagy-related protective mechanisms. Importantly, 3-methyladenine, an autophagy inhibitor, attenuated the cytoprotective effect of ADMSC-Exo, supporting the involvement of autophagy in ADMSC-Exo-mediated protection. Collectively, these findings suggest that ADMSC-Exo protect against OGD-induced cochlear injury by promoting autophagy-associated mitochondrial protection."

Recent studies have demonstrated that the gut microbiota acts as an important metabolic regulator and may play a pivotal role in the onset and progression of PCOS. Patients with PCOS frequently exhibit gut microbiota dysbiosis, which is characterized by reduced microbial diversity, decreased levels of beneficial bacteria, increased levels of pathogenic bacteria, and altered metabolic byproducts. This imbalance may contribute to IR and ovarian dysfunction by activating the toll-like receptor 4/nuclear factor kappa B inflammatory pathway, inducing oxidative stress, and disrupting Wnt/\u03b2-catenin signaling. The Wnt/\u03b2-catenin signaling pathway, a key regulator of follicular development, is frequently aberrantly activated in PCOS. In this narrative review, we summarize the recent advances in understanding the roles of the gut microbiota and the Wnt/\u03b2-catenin signaling pathway in the pathogenesis of PCOS. To this end, we conducted a comprehensive literature search across PubMed, Web of Science, Embase, and Cochrane Library databases, covering publications from January 2012 to March 2026. Ninety-eight articles were included after screening. We further explored therapeutic strategies based on microbiome modulation and signaling pathway targeting, including probiotics, traditional Chinese medicine, ginsenosides, puerarin, fecal microbiota transplantation, and nanoparticle-based ginseng-derived exosomes, thereby providing novel insights into potential therapies for PCOS."

Bone marrow mesenchymal stem cells-derived-exosomes (BMSCs-Exos) regulate osteoclast differentiation and osteoporosis in recent studies. But the mechanisms are still unclear. This research aimed to explore the mechanisms of BMSCs-Exos in osteoclast differentiation and osteoporosis. Exosomes were extracted from BMSCs. THP-1\u202fcells were cultured and treated with BMSCs-Exos. Osteoclast- and autophagy-related gene expression was assessed by qPCR and Western blot, the regulation of YAP1 by RBM15B was analyzed by MeRIP and RNA pull-down, osteoclast differentiation was detected by TRAP staining. HE staining, immunohistochemical staining and micro-CT were employed to assess the impact of BMSCs-Exos on osteoporosis. BMSCs-Exos were internalized by THP-1\u202fcells, promoted YAP1 expression and autophagy, and inhibited osteoclast differentiation. Silencing of YAP1 in THP-1\u202fcells reversed BMSCs-Exos-induced autophagy and the inhibition of osteoclast differentiation; conversely, YAP1 overexpression produced opposite effects. BMSCs-Exos-delivered RBM15B promoted m6A methylation modification of YAP1. Silencing of RBM15B in BMSCs blocked the impact of BMSCs-Exos on autophagy and osteoclast differentiation, whereas RBM15B overexpression exerted opposing influences. Furthermore, BMSCs-Exos suppressed osteoclast differentiation and alleviated osteoporosis in vivo through RBM15B/YAP1 mediated autophagy.

This study examined region-specific proteomic alterations in exosome-enriched small extracellular vesicles (exosome-enriched sEVs) from the cortex and hippocampus induced by neonatal propofol exposure. Using a clinically relevant repeated-dose regimen, C57BL/6 mice received propofol (50\u00a0\u00a0mg/kg, P5-P7).

Intranasal administration has emerged as a noninvasive and promising route for direct nose-to-brain transport, circumventing BBB restrictions. This review explores the potential of intranasal drug delivery as an alternative approach for targeted brain therapy in Alzheimer's disease. It comprehensively discusses the mechanisms of nasal absorption, physiological and formulation-related barriers, and the role of advanced nanocarrier platforms in overcoming these limitations. Emphasis is placed on recent innovations involving polymeric, lipid-based, and vesicular carriers, along with the incorporation of mucoadhesive and permeation-enhancing agents. The present focus is enhancing bioavailability, prolonging drug residence time, and minimizing systemic toxicity. Surface modifications of nanocarriers further facilitates mucosal adhesion and enables effective nose-to-brain transport of encapsulated therapeutic agents. However, clinical translation remains challenging due to interindividual variability in nasal physiology, scalability constraints, and regulatory complexities. Future progress will depend on the rational design of multifunctional nanocarriers, integration of mucoadhesive and stimuli-responsive components, and the use of precision-based formulation strategies."

Consequently, this route has been extensively investigated for treating diverse brain disorders, ranging from acute conditions to neurodegenerative diseases. Despite the advantages and clinical approval of several nasal products, the need for effective disease-modifying therapies (DMTs) of brain disorders remains unmet.

A major challenge to its clinical translation remains the lack of predictive, human-relevant preclinical models. Therefore, this review explores the challenges in nose-to-brain drug delivery development, highlights advanced intranasal delivery strategies for treating brain disorders, and discusses emerging in vitro models for evaluating nose-to-brain delivery efficiency. The work aims to promote the development and clinical translation of intranasal brain-targeted therapeutics."

The blood-brain barrier (BBB), systemic toxicity, and first-pass metabolism are key obstacles. These factors limit the effective drug delivery to the brain. Intranasal administration has emerged as a noninvasive strategy to bypass the BBB. This approach enables direct drug delivery to the brain through the olfactory and trigeminal nerve pathways, commonly referred to as nose-to-brain (N2B) delivery. In this context, chitosan (CS), a biocompatible and mucoadhesive polysaccharide with permeation-enhancing properties, has gained significant interest as a functional material for nanoparticle (NP) engineering. CS-based or CS-coated NP can prolong the residence time on the nasal mucosa and facilitate drug transport to the CNS. This review provides a comprehensive overview of recent advances in CS-based NP for N2B drug delivery across a range of CNS disorders, including neurodegenerative, neuropsychiatric, neoplastic, and infectious conditions. Particular attention is given to formulation strategies, mechanistic insights, and preclinical outcomes. Recent patent applications are surveyed to underscore the translational potential and commercial interest in this technology. Collectively, CS-based NPs effectively address major therapeutic barriers, establishing a transformative and innovative platform in CNS drug delivery."

"abstract_text": "ID: 42546981\nTitle: New insights on microglial lysosomal acidification: A therapeutic target of neurodegenerative diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), maintain brain homeostasis and respond to pathological insults. Microglial dysfunction has been implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Impaired lysosomal function, particularly defective lysosomal acidification, leads to the accumulation of undegraded material, thereby promoting neuroinflammation and neuronal damage. This review examines the mechanisms governing lysosomal acidification in microglia and evaluates its potential as both a therapeutic target and a prognostic biomarker in neurodegenerative diseases. The literature on microglial lysosomal acidification, lysosomal pH regulation, autophagy, and neurodegeneration was searched in PubMed, Scopus, and Web of Science. Relevant mechanistic, preclinical, and translational studies were critically appraised and synthesized. Lysosomal acidification is increasingly recognized as a key regulator of microglial function and homeostasis. Defective acidification, driven by dysregulation of the vacuolar H+-ATPase (V-ATPase) proton pump, TFEB/TFE3 signaling pathways, and lysosomal ion channels such as TRPML1 and TMEM175, impairs autophagic flux and substrate degradation, facilitating the accumulation of neurotoxic aggregates including amyloid-\u03b2 and \u03b1-synuclein. Emerging evidence suggests that the degree of microglial lysosomal acidification may serve as a prognostic biomarker for disease progression and therapeutic response. Restoration or enhancement of lysosomal acidification through pharmacological modulation of lysosomal pH, activation of autophagy, or targeting of key regulatory pathways has been shown to re-establish microglial homeostasis, attenuate neuroinflammation, and confer neuroprotection in preclinical models. Restoration of microglial lysosomal acidification represents a promising therapeutic strategy for neurodegenerative diseases. A deeper understanding of the molecular mechanisms regulating lysosomal acidification in microglia may facilitate the identification of novel biomarkers and therapeutic targets, ultimately contributing to the development of innovative interventions for neurodegenerative disorders."

This research investigates the role of autophagy in renal damage caused by GoAstV in goslings. The findings indicated that GoAstV infection in goslings resulted in characteristic clinical manifestations, with renal tissues displaying tubular swelling, inflammatory infiltration, and autophagosome formation. In vivo experiments demonstrated a significant upregulation of mRNA levels for autophagy-related factors, including AMPK, LC3A, ATG5, ATG7, P62, Beclin1, AMBRA1 and GABARAPL1, while mTOR and LC3B levels were notably decreased. At 3 dpi, the protein expression levels of ATG5, Beclin1, and LC3B II/I increased, while P62 levels decreased, suggesting autophagy activation. In vitro analyses revealed that GoAstV infection led to enhanced autophagy; however, the concurrent upregulation of LC3B II/I and P62 proteins suggested an obstruction in the autophagic flux. Upon the inhibition of autophagy with 3-methyladenine (3-MA, autophagy inhibitor), there was a significant reduction in the expression of autophagy-related factors, accompanied by a marked decrease in viral replication rates. In conclusion, GoAstV infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux. The virus exploits autophagosomes for replication, ultimately resulting in kidney damage. The application of 3-MA effectively inhibits this autophagic process and diminishes viral replication."

Selenium nanoparticles (Se-NPs) are neuroactive agents owing to their antioxidant and anti-inflammatory activities. Additionally, physical and mental activities (Ph&M) exert neuroprotective effects by optimizing the release of both neurotransmitters and growth factors. However, their neuroprotective effects against SI-induced depression are still poorly investigated. We aim to explore the neuroprotective effect of Se-NPs, Ph&M, and their combination to guard against the harmful effects of SI-induced depression in a rat model. Fifty Sprague Dawley rats were randomly allocated into five groups: control, SI, Ph&M, orally administered Se-NPs (0.1\u00a0mg/kg), and a combination group. Neuroprotective activity was quantitatively estimated pharmacologically, biochemically, histologically, and behaviorally. SI caused behavioral and biochemical alteration in the rat model, decreasing neurotransmitter levels, increasing the transcription of inflammatory response genes (TLR4 and NF-\u03baB), and consequently increasing the production of the cytokines TNF-\u03b1 and IL-1\u03b2. It also activated the proinflammatory NLRP3/caspase-1 pathway. The ER stress parameters PERK, CHOP, and GRP78 were significantly elevated. Impairment of autophagy and increased neurodegeneration were detected via the decline of AMPK/SIRT-1/Beclin-1 PI3K/AKT gene expression and m-TOR overexpression. Decreased expression of TrkB and CREB mRNA and consequent decline in brain-derived neurotropic factor were recorded. SI caused a drastic drop in Wnt3a and \u03b2-catenin levels and increased GSK3\u03b2 activity affecting neuroplasticity and cognitive functions. Administration of Se-NPs and/or application of Ph&M, especially their combination, provided significant protection against prior SI effects.

We investigated the role of CNOT11 in cellular stress responses using siRNA-mediated knockdown, immunoblotting, immunoprecipitation, transcriptomic analysis, quantitative RT-PCR, ELISA, cycloheximide chase assays, actinomycin D treatment, and poly(A) tail analysis. CNOT11 depletion did not markedly alter the expression of other CCR4-NOT subunits but reduced the association of CNOT10 with the complex. CNOT11 knockdown was associated with LC3-II accumulation, transcriptional upregulation of autophagy-related genes, and changes in AMPK/ULK1 signaling. Increased IL-6 expression and secretion and enhanced STAT1 and STAT3 phosphorylation were also observed. IL-6 knockdown or STAT3 inhibition partially attenuated LC3-II accumulation. Increased IL-6 expression was associated with elevated transcription, without detectable changes in mRNA stability or poly(A) tail length. These findings suggest that CNOT11 depletion is associated with LC3-II accumulation and other autophagy-related responses, with IL-6-JAK-STAT signaling contributing partially to this phenotype. Definitive assessment of autophagic flux and the causal positioning of IL-6 signaling will require further studies using gold-standard flux assays and IL-6 rescue or neutralization approaches."

However, liver sinusoidal endothelium-mediated nanoparticle elimination remains far less understood than liver macrophage uptake despite both processes being involved in hepatic detoxification. Using water-soluble Au25(o-MBA)18 (o-MBA: o-mercaptobenzoic acids) with optimized local hydrophobicity for weak protein-binding affinity and high endothelium targeting as probes, we report an exosome-mediated systemic clearance for endocytosed nanoclusters in sinusoidal endothelial cells. Au25(o-MBA)18 can effectively avoid phagocytosis by liver macrophage, are initially endocytosed by sinusoidal endothelial cells through clathrin-dependent endocytosis, processed through endosomal pathways, and released as exosomes containing nanoclusters into the bloodstream. During the exosome biogenesis, Au25(o-MBA)18 progressively transform into flower-like aggregates (approximately 100 nm). These circulating exosomes traverse the glomerular membrane through autophagy in glomerular endothelial cells and podocytes before urinary excretion. Here, this exosome-mediated pathway converts exogenous ultrasmall gold nanoparticles into biocompatible endogenous exosome-enveloped cargos for systemic circulation with reduced toxicity, providing a foundation for developing next generation of safe and effective nanomedicines."

Previously reported mouse models exhibited reduced birthrate and survival of affected males, greatly limiting their experimental utility. Here we describe a new mouse model carrying the clinically relevant Sms p.Gly56Ser (SmsG56S) allele in which viable males are recovered at Mendelian ratios, enabling generation of adequately powered cohorts. Hemizygous males produce markedly reduced SMS protein across tissues, recreating the biochemical hallmark of SRS, an elevated spermidine:spermine ratio. SmsG56S/Y males exhibit reduced body size, altered body composition, decreased locomotor and exploratory behaviors, and reduced seizure threshold, aligning with clinical features reported in SRS patients. Serum LDL, HDL, and cholesterol levels were reduced, while brain histology revealed modest region-specific astrocytic changes. Comprehensive polyamine profiling revealed tissue-specific biochemical disturbances, highlighting putrescine elevation in the brain and informing development of translational strategies and windows for intervention. Overall, this improved model reproduces multiple key aspects of the human SRS phenotype and provides a robust platform for mechanistic studies and preclinical evaluation of therapies."

The estrogen decline increases vulnerability to mood disorders, but the molecular mechanisms underlying stress resilience remain unclear. Here, we identify hippocampal neuronal progranulin (PGRN), a secreted neuroprotective glycoprotein, as a key regulator of affective resilience under estrogen-deficient conditions. Ovariectomy (OVX) reduces hippocampal neuronal PGRN expression and induces anxiety- and depression-like behaviors, whereas estradiol supplementation restores both PGRN levels and behavior. Adeno-associated virus (AAV)-mediated overexpression of PGRN alleviates affective deficits across OVX, 4\u2011vinylcyclohexene diepoxide (4-VCD)-induced ovarian failure, and natural aging models, while neuronal, but not microglial, Grn deletion exacerbates stress susceptibility. Mechanistically, PGRN restores lysosomal protease activity, normalizes autophagic flux, activates AMP-activated protein kinase (AMPK) phosphorylation, and rescues mushroom spine loss, thereby restoring cellular and synaptic homeostasis. Intracerebral recombinant PGRN rescues OVX\u2011induced behavioral deficits, and the blood-brain barrier (BBB)-permeable fragment granulin-E (GRN\u2011E) confers similar protection after systemic administration.

As a key transcription factor in reproductive modulation, the specific role of GATA4 in the testicular microenvironment of Bactrian camels remains unclear. This study investigates the expression patterns of GATA4 in the testicular tissue during estrus and anestrus phases, alongside its potential regulatory effects on Sertoli cells (SCs) function. Utilizing mRNA sequencing, we analyzed testicular samples in estrus (n\u202f=\u202f3) and anestrus (n\u202f=\u202f3), identifying 291 differentially expressed genes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed that GATA4 was involved in reproduction-related processes, including tight junction formation, autophagy, and cell cycle regulation. Notably, validation showed that GATA4 expression was significantly upregulated in testicular tissue during the anestrus period, with its protein localized primarily in SCs. Gain- and loss-of-function assays revealed that altered GATA4 expression is associated with changes in autophagy-related marker profiles, evidenced by a lower LC3II/LC3I ratio, decreased Beclin-1, and increased P62 expression level. Silencing GATA4 induced opposite alterations in these autophagy-associated molecular markers, and these molecular changes are associated with modified mTOR/NF-\u03baB pathway expression. Additionally, GATA4 influences SCs apoptosis and G0/G1 cell cycle arrest and these cellular phenotypic changes are accompanied by alterations in the PI3K/AKT pathway, which correlates with changed levels of BAX, Caspase-3, BCL2, and CDK1. And moreover, GATA4 modulates the expression of the tight junction markers ZO-1 and Occludin, and these remodeling events are associated with modified WNT1/\u03b2-catenin signaling. In conclusion, GATA4 exhibits dynamic expression patterns throughout the reproductive cycle, which correlates with the modulation of multiple biological processes in SCs, including autophagy-related marker remodeling, apoptosis regulation, and tight junction marker remodeling. This study's findings provide a key molecular target for elucidating the seasonal reproductive mechanism and reproductive regulation of Bactrian camels and enrich the current understanding of reproductive regulatory mechanisms in this species."

Autophagy is essential for endothelial homeostasis, yet its role in aldosterone-mediated vascular dysfunction remains unclear. We tested whether aldosterone impairs autophagic flux and whether restoring autophagy via Beclin1 (BCN1) activation protects vascular and cardiac function. Endothelial and vascular responses to aldosterone were assessed in wild-type mice, BCN1 gain-of-function mice (Becn1), and mice treated with spermidine or a BCN1-activating TB-peptide. Vascular function, nitric oxide (NO)/reactive oxygen species (ROS) production, autophagy markers, endothelial migration, and cardiac fibrosis were evaluated using wire myography, fluorescence assays, Western blotting, confocal microscopy, migration assays, and histology. Aldosterone impaired endothelium-dependent relaxation, decreased NO, increased ROS, and disrupted autophagic flux in an MR-dependent manner, indicated by LC3 accumulation and reduced p62 and BCN1 expression. Spermidine restored endothelial function and normalized NO and ROS levels. BCN1 gain-of-function mice were protected from aldosterone-induced endothelial dysfunction and exhibited reduced coronary and myocardial fibrosis. TB-peptide activation of BCN1 enhanced autophagic flux, improved vascular function, decreased cardiac fibrosis, and rescued endothelial migration impaired by aldosterone.

The pathophysiology of SCI involves many aspects. Current treatments, such as early decompression and glucocorticoids, target single pathways and show limited efficacy with safety concerns. In this context, interventions based on the incretin system are now considered attractive candidates for SCI intervention. This review comprehensively outlines the mechanisms underlying microenvironmental imbalance following SCI and explores glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists as promising options. These agents, recognized for their role in managing diabetes and body weight, demonstrate substantial pleiotropic effects beyond simple glycemic regulation. These beneficial actions include neuroprotection, anti-inflammatory effects, and the promotion of tissue repair. Preclinical SCI studies have indicated that GLP-1 receptor agonists and GIP receptor agonists reduce inflammation by shifting microglia/macrophages to anti-inflammatory phenotypes, suppress apoptosis, increase autophagy, alleviate oxidative stress, promote axonal regeneration, improve the injury microenvironment, and have the potential to regulate immune cells. Related research in other neurological disorders supports these mechanisms, with dual agonists showing superior efficacy. GLP-1 receptor agonists and GIP receptor agonists suggest significant potential to address the multifaceted pathology and associated metabolic complications of SCI.

Physiological adaptations to fasting are reflected in favorable alterations in biomarkers and metabolic processes. This review examines the current evidence on IF by analyzing studies retrieved through schematic searches of the MEDLINE via PubMed database, Embase and ScienceDirect using specific keyword combinations. It focuses on commonly practiced regimens- Time-restricted eating (TRE) (16/8 method), Alternate-day fasting (ADF), the 5:2 intermittent energy-restriction diet and One meal a day (OMAD) approaches and explores their effects on cardiovascular function, metabolic regulation, cognitive performance and longevity. Various IF regimens including the TRE (16/8 method), ADF, the 5:2 diet and OMAD approaches are discussed in relation to their effects on cardiovascular health, cognitive function, metabolic regulation, aging and longevity. While most finding highlight significant health benefits, inconsistencies and methodological limitations are also reported. Mechanistically, IF orchestrates a coordinated metabolic response through modulation of key nutrient sensing pathway such as AMP activated protein kinase (AMPK), mechanistic target of rapamycin (mTOR) and unc-51-like kinase 1 (ULK1). These cascades interact with Sirtuins (SIRT1/3), peroxisome proliferator activated receptor gamma coactivator-1\u03b1 (PGC-1\u03b1) and the transcription factor EB (TFEB) to regulate autophagy, mitochondrial biogenesis, oxidative stress defense and cellular repair.

No definitive methods exist to repair damaged neurons. Vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) are two neuroprotective agents that work synergistically. However, these large molecular proteins have difficulty crossing the blood-brain barrier (BBB). Extracellular vesicles (EVs) offer superior targeting and low immunogenicity, making them excellent carriers. In this study we examined the protective effects of VEGF and NGF in a cell model and evaluated the therapeutic potential of VEGF-NGF contained within EVs in PD rats. EVs were isolated using sequential differential centrifugation and characterized using transmission electron microscopy, nanoparticle tracking analysis, and western blotting (WB). VEGF and NGF were loaded into the EVs using a saponin-assisted method to create VEGF@EVs, NGF@EVs, and VEGF/NGF@EVs. The viability of 6-hydroxydopamine hydrochloride (6-OHDA)-induced SH-SY5Y cells was measured using the cell counting kit-8 assay before and after treatment with VEGF and NGF. Autophagy levels were assessed using WB, and the role of autophagy was further explored using the autophagy inhibitor chloroquine. Unilateral PD rat models were established via stereotactic injection of 6-OHDA into male Sprague-Dawley rats. Behavioral changes were monitored before and after treatment. Neuronal recovery, neurotransmitter levels, and autophagy levels in the rat brains were evaluated using immunohistochemistry, enzyme-linked immunosorbent assay, and WB. VEGF/NGF@EVs significantly enhanced the viability of 6-OHDA-induced SH-SY5Y cells. A complete autophagic process was identified as essential for this protective effect. The intranasal administration of VEGF/NGF@EVs improved motor behavior in PD rats, with performance better than that of single growth factor treatments. The number of tyrosine hydroxylase (TH)-positive neurons, TH protein expression, and dopamine content were significantly increased. In addition, the level of autophagy in the rat substantia nigra was elevated. VEGF/NGF@EVs exert protective effects in both in vitro and in vivo 6-OHDA-induced PD models by promoting autophagy, demonstrating greater efficacy than either growth factor alone. By transplanting VEGF/NGF@EVs into PD rats, we showed that these vesicles can effectively cross the BBB and deliver targeted therapy to the central nervous system.

Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities."

Among those, the short isoform of Nuclear Receptor Coactivator 7 (NCOA7-AS) has been shown to inhibit IAV entry and more especially the fusion between endosomal and viral membranes. Ectopic expression of NCOA7-AS leads to the increased acidification of the endolysosomal pathway, putatively through NCOA7-AS interaction with the vacuolar ATPase (V-ATPase). However, the precise mechanism of action of NCOA7-AS is not fully understood. Here, we identified the cellular partners of NCOA7-AS by mass spectrometry, including the V-ATPase subunits known to interact with NCOA7-AS. A point mutation disrupting the interaction with the V-ATPase led to loss of antiviral activity against IAV, demonstrating that V-ATPase engagement is required for the antiviral phenotype. Moreover, sorting nexin (SNX) 1/2/5/6 were identified as novel partners of NCOA7-AS. These proteins are involved in retrograde transport of cellular cargoes from endosomes to the trans-Golgi network. We revealed that SNX5/6 interacted directly with NCOA7-AS and were essential for NCOA7-AS antiviral activity against IAV. Interestingly, crystal structures of NCOA7-AS/SNX5 complexes showed that the SNX5-interaction motif in NCOA7-AS was similar to those found in known cargoes of SNX5/6. In addition, we could pinpoint several critical residues that were important for binding and antiviral activity. Collectively, our study identifies novel essential partners for NCOA7-AS antiviral activity and the structural basis for their interaction."

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."

Moreover, we discuss the potential role of TMEM106B as an important modifier of the protein TDP-43 neuropathology associated with the GRN mutation in this case. The patient underwent detailed clinical assessment, serial neuropsychological evaluation, brain MRI, cerebrospinal fluid analysis, whole-exome sequencing, and next generation sequencing. A postmortem neuropathologic examination was performed to confirm the diagnosis. The patient presented slowly progressive paresthesia, cerebellar ataxia, dysarthria, and later cognitive and behavioral changes. Genetic testing revealed a heterozygous PRNP P102L variant and an unpenetrated GRN p.R110X variant; a protective TMEM106B polymorphism associated with TDP-43 pathology was also identified. Neuroimaging demonstrated progressive cerebellar and parietal atrophy with asymmetric left frontal opercular and insular involvement. The clinical course was dominated by a cerebellar GSS phenotype. The patient died 4 years after symptom onset. Neuropathology confirmed GSS, nevertheless without detectable TDP-43-associated neuropathology. This case highlights the diagnostic complexity of rare neurodegenerative disorders and illustrates that pathogenic variants may not influence phenotypic expression. Comprehensive genetic testing should be considered in atypical cases, as certain genetic variants may contribute to phenotypic variability and represent potential modifiers of phenotypic expression."

Here, we investigate whether the CT Receptor plays a role in cancer cell survival. In cancer cell lines, knockdown of CALCR disrupts the cell cycle and induces apoptosis, supporting an essential pro-survival role. The CALCR gene produces three main transcripts in humans, of which Transcript 1 encodes CALCRb mRNA including exon 10 and is translated into the CTb Receptor isoform, and Transcripts 2 and 3 which are translated into the CTa Receptor. CALCRb expression is conserved across a diverse range of mammalian species. We examined the expression of all CT Receptor isoforms (CALCRtotal) and CALCRb expression in four high-grade glioma stem-like cell lines and in U-87 MG glioblastoma cells. Using qPCR, we observed stable levels of both CALCRtotal and CALCRb expression under conditions of autophagy or apoptosis, consistent with a requirement for CALCRb in cell survival. As alternative splicing (AS) of key genes in cancers confers tumour resilience, we investigated AS of CALCR transcript 2 using long-read nanopore sequencing. Unexpectedly, we discovered a novel AS event causing inclusion of exon 10 within Transcript 2 in all glioblastoma cell lines investigated. This finding, together with stable CALCRb expression under cellular stress and the finding by other groups confirming that knockdown of CT Receptor compromises cell survival, implicates the CTb Receptor as a potential oncoprotein."

Circular RNAs (circRNAs), characterized by their covalently bonded single-stranded loop configuration, have been identified as functional regulators across various cancer types. Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression."

MicroRNAs (miRNAs), which are critical post-transcriptional regulators, have emerged as important modulators of animal behavior. This study investigated the molecular basis of aggression in pigs ( Sus scrofa), focusing on miRNA-mediated regulation. Hypothalamic miRNA-sequencing of the most aggressive ( n=4) and least aggressive ( n=4) piglets identified nine differentially expressed miRNAs. Among these, miR-27a was significantly upregulated in aggressive individuals. Functional assays demonstrated that both porcine miR-27a and its human ( Homo sapiens) ortholog has-miR-27a-3p, suppressed autophagy, apoptosis, and neuronal plasticity in primary porcine neurons and human SH-SY5Y neuroblastoma cells. To clarify the underlying mechanisms, mRNA-sequencing was performed on porcine neurons transfected with miR-27a mimics or negative controls, identifying 436 differentially expressed genes (84 upregulated and 352 downregulated). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses highlighted eight genes- CBL, PRKCA, SLC38A1, ZBTB16, AANAT, CYP1A1, SLC7A11, and NTRK2-associated with tryptophan metabolism, oxidative stress, and long-term synaptic depression. Bioinformatic analysis and dual-luciferase reporter assays confirmed that miR-27a directly targets the 3'-UTR of PRKCA, thereby suppressing of autophagy, apoptosis, and neuronal plasticity.

Despite advances in antiseizure medications, effective epilepsy management remains challenging because of pharmacoresistance, limited blood-brain barrier (BBB) permeability, inadequate intracerebral drug accumulation, and systemic toxicity. Moreover, currently available therapies primarily provide symptomatic seizure control without addressing the fundamental pathological processes involved in epileptogenesis, neuroinflammation, oxidative stress, and neuronal degeneration. Intranasal administration has emerged as an attractive non-invasive approach for direct brain targeting, enabling therapeutic agents to circumvent BBB-associated transport barriers and access the central nervous system through the olfactory and trigeminal neural pathways. In this context, biodegradable nanomedicine platforms have gained considerable attention due to their favorable biocompatibility, controlled drug release, enhanced mucosal permeation, and potential for targeted intracerebral delivery. This review provides a comprehensive and critical overview of recent advances in intranasal biodegradable nanomedicine for epilepsy, integrating current knowledge on disease pathophysiology, biological and pharmaceutical barriers, nose-to-brain transport mechanisms, biodegradable nanoparticle platforms, and emerging functionalization strategies. Importantly, the review critically evaluates the current evidence, distinguishing encouraging preclinical findings and discusses the major translational challenges that continue to hinder clinical implementation. Finally, future perspectives are highlighted to identify opportunities for developing safer, more effective, and clinically translatable therapies for epilepsy management."

However, accumulating evidence over the past several decades has established them as the three principal endogenous gasotransmitters that regulate a wide spectrum of physiological and pathological processes. Unlike conventional signaling molecules, gasotransmitters diffuse freely across biological membranes and exert potent biological effects through receptor-independent mechanisms, including redox-sensitive post-translational modifications and modulation of heme-containing proteins. Although the individual functions of NO, CO, and H2S have been extensively reviewed, emerging studies indicate that these gaseous mediators rarely operate in isolation. Instead, they form a highly integrated signaling network characterized by direct chemical interactions, reciprocal enzymatic regulation, and convergence upon common downstream pathways. In this mini-review, we propose the concept of a \"Gasotransmitter Trio Network,\" emphasizing the molecular crosstalk among NO, CO, and H2S as a fundamental determinant of cellular homeostasis. We first summarize the biosynthetic pathways and major signaling mechanisms of the gasotransmitter trio, including S-nitrosylation, persulfidation, and heme-dependent regulation. We then discuss recent advances revealing how interactions among these gases generate novel bioactive intermediates and coordinate redox signaling. Particular attention is given to the emerging roles of gasotransmitters in regulating ferroptosis, autophagy, and mitophagy by modulating iron metabolism, lipid peroxidation, mitochondrial quality control, and antioxidant defense systems. These findings support a unified framework in which gasotransmitters function as master regulators of cellular fate under conditions of physiological and pathological stress. Finally, we highlight recent progress in stimuli-responsive donors, CO-releasing molecules (CORMs), NO-releasing materials (NORMs), H2S donors, and advanced nanoplatforms that enable spatiotemporally controlled gas delivery. We propose that future therapeutic strategies will increasingly rely on programmable multi-gas systems that recapitulate endogenous gasotransmitter networks. Collectively, this review provides a systems-level perspective on gasotransmitter biology and outlines emerging opportunities for the development of precision gas medicine in cardiovascular, neurodegenerative, inflammatory, metabolic, and malignant diseases."

Shikonin, a natural anti-tumor compound, exerts anti-BCa activity, yet its direct molecular target and underlying mechanism remain undefined. This study aimed to identify the direct target of shikonin in BCa and to elucidate the mechanism by which shikonin suppresses tumor progression. The anti-BCa effects of shikonin were assessed in vitro and in vivo. Drug affinity responsive target stability (DARTS) combined with 4D quantitative proteomics identified shikonin's direct target, which was validated by molecular docking and cellular thermal shift assay (CETSA). Gain- and loss-of-function experiments and ER-phagy-related assays elucidated the underlying molecular mechanism. Shikonin inhibited BCa cell proliferation, migration, invasion and induced senescence in vitro, and suppressed tumor growth in vivo with no obvious toxicity. Deoxyribonuclease 2 (DNASE2) was identified as shikonin's direct target; shikonin promoted DNASE2 ubiquitination and degradation without altering its mRNA level. DNASE2 was highly expressed in BCa and correlated with poor prognosis, and its knockdown mimicked and enhanced shikonin's anti-BCa effects. Mechanistically, shikonin targeted DNASE2 to downregulate Reticulon 3 (RTN3), thereby inhibiting RTN3-dependent endoplasmic reticulum autophagy (ER-phagy) in BCa. This study first identifies DNASE2 as the direct target of shikonin in BCa, and reveals that shikonin exerts anti-BCa activity by promoting DNASE2 ubiquitination/degradation to inhibit the DNASE2/RTN3 axis-mediated ER-phagy. The DNASE2/RTN3 axis is a novel ER-phagy regulatory node in BCa, providing a potential therapeutic target for BCa treatment."

How the predicted regulatory potential of these miRNAs differs among the milks of different animals most relevant to human nutrition has not been systematically compared. Here, we performed an integrative in silico analysis of publicly available small-RNA sequencing data from 29 milk and milk-cell samples of human, cow, goat, and donkey origin. miRNAs were quantified against human (hsa) miRBase references-thereby restricting the analysis to evolutionarily conserved miRNAs with human orthologs-and their predicted effect on the human transcriptome was modeled by integrating predicted (mirDIP database) and experimentally supported (TarBase v9 database) miRNA-target interactions into a per-gene, per-species weighted targeting score. Because miRNAs act predominantly as repressors, this score is read as a prediction of which genes would be post-transcriptionally down-regulated in a recipient. miR-148a-3p dominated the exosomal spectrum of all four species (human, cow, goat, and donkey; \u224821.5% of pooled abundance), and the twenty most abundant miRNAs accounted for roughly three quarters of the signal.

Species-restricted gene sets recapitulated biologically plausible programs, including a human-biased neuronal/axon-guidance and chromatin module, a donkey-biased transcriptional, epithelial, and immune (CD47) module, and a ruminant lipid/cholesterol and insulin-mTOR module. Across categories, we observed a reproducible confidence-exclusivity trade-off. We emphasize that these results are computational predictions that assume dietary miRNA uptake and do not constitute experimental validation. We provide the complete targetome as a hypothesis-generating resource to prioritize candidate genes, pathways, and milk types for future functional, nutritional, and epigenetic investigation. Across the 29 samples from the four species, miRNA composition segregated by species (silhouette width = 0.82, a cluster-separation measure ranging from -1 to 1, with values near 1 indicating well-separated groups) and the category structure exceeded a permutation null, indicating that the between-species signal is robust to differences in dataset origin and milk state."

On the other hand, excessive and prolonged ER stress leads to apoptosis. However, the relationships between different UPR branches and apoptosis or autophagy vary in cancer cells of different origins and depend on the extent and nature of the stress signal. This study was designed to establish the role of ER stress sensors protein kinase RNA-like endoplasmic reticulum kinase (PERK) and inositol-requiring enzyme 1 (IRE1\u03b1) in apoptosis or autophagy signaling in T-lymphoblastic leukemia MOLT-3 cells via the RNA interference method. The cells were transfected with small interfering RNAs (si-PERK, si-IRE1\u03b1, or si-Cont) for 6 h and further cultured under normal conditions for 72 h to provide an insight into chronic effects of the gene silencing. The expression of apoptosis and autophagy effectors at the mRNA and protein levels was compared using RT-PCR and Western blot assays, respectively. Transfection of the cells with PERK siRNA led to a significant decrease in PERK protein and gene expression, and decreased phosphorylation of its downstream effector eukaryotic initiation factor 2\u03b1 (eIF2\u03b1). PERK silencing was accompanied by activation of apoptosis-related genes and proteins-BCL2-associated X (Bax), caspase-3, C/EBP homologous protein (CHOP), while the levels of autophagy markers (Unc-51 like autophagy activating kinase 1 (ULK1), Beclin-1, and microtubule-associated proteins 1A/1B light chain 3 (LC3A/B)) remained stable.

IRE1\u03b1 RNA interference did not affect the levels of the pro-apoptotic marker Bax, but suppressed caspase-3, CHOP, c-Jun N-terminal kinase (JNK), and autophagy signaling molecules (ULK1, Beclin-1, LC3A/B) at both the transcriptional and translational levels. These results indicate that the PERK pathway is an important contributor to the survival of MOLT-3 cells under basal ER stress, while PERK depletion compromises the resistance of cells to UPR-mediated apoptosis. The IRE1\u03b1 UPR branch is directly linked with autophagy-dependent signaling, although IRE1\u03b1 knockdown exerted a more complicated influence on the cells, probably via activation of multiple pro-death and compensatory pro-survival regulatory mechanisms."

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]\nHypothesis: Intranasal delivery of Spermidine-modified Ginseng Extracellular Vesicles (S-GEVs) loaded with GRN mRNA exploits the cribriform plate anatomy to bypass the blood-brain barrier, providing a neuro-targeted delivery system for progranulin gene therapy that acts synergistically with spermidine-induced autophagy to suppress pathological TMEM106B amyloid accumulation and restore endolysosomal homeostasis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe proposed hypothesis posits that a composite nanotherapeutic consisting of ginseng-derived extracellular vesicles (GEVs) functionalized with spermidine and loaded with *GRN* mRNA could ameliorate neurodegenerative conditions characterized by *GRN* haploinsufficiency and TMEM106B protein aggregation. The conceptual framework relies on three intersecting domains: (1) nasal-to-brain delivery mechanisms circumventing the blood-brain barrier (BBB), (2) the intrinsic neuroprotective and autophagy-inducing properties of spermidine, and (3) the endolysosomal roles of PGRN and TMEM106B. While the evidence validates these individual components, the specific synergy of an S-GEV/GRN mRNA delivery system remains a novel, untested computational framework.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent evidence confirms that the blood-brain barrier (BBB) presents a formidable obstacle to neurotherapeutics, with \"over 98% of small-molecule drugs and nearly all biologics fail to cross this barrier.\" Intranasal delivery offers a non-invasive bypass, as identified by the presence of \"a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations\" which facilitate drainage to the cervical lymph nodes. Ginseng-derived exosomes have been characterized as \"natural nanovesicles\" offering \"large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers.\" \n\nRegarding the therapeutic cargo, *GRN* mutations and TMEM106B aggregation are central to neurodegeneration, as \"The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases.\" Furthermore, \"Recent new studies reported that TMEM106B proteins form intracellular amyloid filaments which universally exist in various neurodegenerative diseases, sometimes being the dominant form of protein aggregation.\" Restoration of progranulin is hypothesized to alleviate lysosomal dysfunction. Concurrent induction of autophagy is essential, as \"Spermidine, a naturally occurring polyamine, has emerged as a candidate modulator of brain aging because it regulates autophagy, mitochondrial function, oxidative balance, and neuroinflammatory signaling.\" The integration of these elements into a single S-GEV platform represents a sophisticated, if currently unverified, therapeutic modality.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* TMEM106B aggregation is not merely a loss-of-function event but involves the formation of universal intracellular amyloid filaments across multiple neurodegenerative diseases.\n* Nasal delivery routes, specifically through arachnoid fenestrations at the olfactory bulb, are increasingly recognized as viable channels for protein and nucleic acid transport.\n* Ginseng-derived exosomes are effectively serving as \"natural nanocarriers\" capable of cross-kingdom delivery of metabolites and therapeutics.\n* Spermidine's efficacy as a neuroprotector is dosage-dependent, where \"low doses has the potential to be a general-purpose neuroprotector.\"\n* Autophagic flux, regulated by proteins such as Beclin-1 and the mTOR/AMPK axis, is a critical regulatory node for both progranulin and TMEM106B-associated pathologies.\n* The TMEM106B/progranulin endolysosomal-lipid axis is essential for metabolic homeostasis; its disruption leads to protein accumulation.\n* Emerging \"Gasotransmitter Trio Networks\" (NO, CO, H2S) modulate autophagy and mitophagy alongside the protein-based pathways of *GRN* and TMEM106B.\n* Recent proteomics studies confirm that CLK4 regulates autophagy-related proteins (e.g., SQSTM1) in cancer and degenerative models, highlighting broader splicing/autophagy interactions.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Most reported pathogenic mutations are nonsense, frameshift, or splicing mutations, resulting in a premature stop codon, degradation of mutated mRNA and consequent protein haploinsufficiency. In this study, we analysed four subjects with FTD who had low plasma progranulin levels but no mutation detectable by sequencing of GRN, to disclose the underlying genetic cause of disease. Multiplex ligation-dependent probe amplification (MLPA) method was applied to search for rearrangements in GRN. Region-specific polymerase chain reaction (PCR) and Sanger sequencing were performed to define the breakpoint. Quantitative real-time PCR (qRT-PCR) on GRN mRNA and haplotype sharing analysis were also performed. MLPA revealed in all the subjects the same heterozygous deletion, and a possible common ancestor was suggested by haplotype sharing. PCR and sequencing allowed us to define the size of the deletion (3028\u00a0bp), that removes part of GRN promoter, exon 1 including the transcription start site and most of the intron 1, and the breakpoints. qRT-PCR showed reduced level of mRNA, confirming the pathological nature of the deletion. In this study, we described a GRN heterozygous gross deletion which removes the consensus sequences for transcription factors and the transcription start site, leading to a reduced levels of plasma progranulin. Our study indicates that GRN rearrangements, although not common, should be investigated in patients with FTD who show low plasma progranulin levels but no GRN mutations detectable by DNA sequencing.\n\nID: 42518684\nTitle: Nanoparticles Navigating the Blood-Brain Barrier for Neurodegenerative Therapy.\nAbstract: The blood-brain barrier (BBB) blocks most drugs from entering the brain. Over 98% of small-molecule drugs and nearly all biologics fail to cross this barrier. Nanoparticles (NPs) provide multiple ways to bypass the BBB. These include receptor-mediated transcytosis, adsorptive-mediated transport, and intranasal delivery. NPs can also modify disease-related pathways. For example, they promote amyloid-\u03b2 clearance, reduce tau phosphorylation, and reprogram neuroimmune responses. Many preclinical studies have shown promising results in Alzheimer's, Parkinson's, and Huntington's diseases. However, no NP-based therapy has moved beyond early-stage clinical trials. Several issues remain unresolved. Direct comparisons between different NP platforms are lacking. The long-term toxicity of NPs in the brain is not well understood. Animal models also do not accurately reflect human disease. We suggest that future work should focus on standardized characterization, better predictive models, and clinical trial designs that address NP diversity. Researchers should also compare NP therapies with existing treatments in a rigorous manner.\n\nID: 42518653\nTitle: Magnesium-containing intramedullary nails promote fracture healing in type 2 diabetic animal model via recruiting regulatory T cells into the fracture callus.\nAbstract: Magnesium-containing intramedullary nails (Mg-IMN) have been shown to promote fracture healing across various types of fractures, including osteoporotic and atypical femoral fractures. However, their role in the challenging chronic inflammatory type 2 diabetes (T2D) fracture healing remains unclear. In this study, we investigated the effect of Mg-IMN on fracture healing in a T2D mouse model and explored the involvement of regulatory T cells (Tregs) in this process. Our results demonstrated that Mg-IMN promotes fracture healing in Leprdb/db T2D mice. At 5 days post-fracture, flow cytometry showed an increased number of Tregs in the fracture callus. Notably, depletion of Tregs via injection of PC61 neutralizing antibody abolished the promotive effect of Mg-IMN, indicating the critical role of Tregs in this process. Bulk RNA sequencing of the bone callus at 5 days post-fracture revealed significant enrichment of pathways related to chemokine signaling and CCR chemokine receptor interactions, suggesting a mechanism of Treg recruitment. Transwell migration assays in vitro preliminarily indicated the chemotactic effect of CCL19 and CCL21 in recruiting Tregs. Furthermore, Mg2+ treatment enhanced the mRNA expression levels of amphiregulin (Areg) and granulin (Grn) in Tregs, as indicated by qRT-PCR analysis. These findings may pave the way for new applications of Mg-IMN in fracture repair and provide unique insights into osteoimmunology during the complex process of T2D fracture healing.\n\nID: 42511573\nTitle: Evolution of Recurrent Myxofibrosarcoma of the Thoracic Wall at Single-Cell Resolution: A Case Report.\nAbstract: Myxofibrosarcoma (MFS) is a common yet understudied type of soft tissue sarcoma. It is characterized by diverse cellular morphology, unusual growth patterns, and a propensity for local tumor recurrences. A 76-year-old patient underwent multiple surgical removals of MFS recurrences of the thoracic cavity and surrounding tissues with the subsequent development of metastases. Single-cell RNA sequencing was used to analyze the earlier (R7) and later (R8) MFS recurrences, with R8 removed less than a year before the detection of metastases in the lungs. The earlier MFS recurrence displays tumor clusters with multiple immunomodulatory markers (DKK1, APP, CD24, GRN) and genes involved in lipid metabolism and cell stress (DDIT3, ABCA1, ABCA10, ATF4, NEU1), combined with an anti-inflammatory TME. The later MFS recurrence shifts to a functionally less diverse phenotype, enriched in fibroblast-typical markers (POSTN, NES, COL1A1/A2), and a pro-inflammatory TME. The proliferative (MKI67, TOP2A, BUB1B) and mRNA splicing and processing (SNRNP70, SRSF2/5/11, RSRP1, LUC7L/7L3, SRRM1/2) tumor clusters are observed in both MFS recurrences, and their signatures match the previous data on primary MFS tumor populations. ScRNA-seq analysis of two subsequent MFS recurrences from one patient show a change from functionally diverse to more uniform ECM remodeling enriched tumor populations, an accompanying shift to the pro-inflammatory TME, and the presence of two common tumor clusters enriched in proliferative and mRNA-processing gene signatures.\n\nID: 42481908\nTitle: A Study on the Effects of Intranasally Administered Liquid Crystalline Nanoparticles Loaded with Salvianolic Acid B in Vascular Dementia.\nAbstract: Salvianolic acid B (SalB) is a bioactive polyphenol with therapeutic potential for vascular dementia (VD), but poor penetration across the blood-brain barrier (BBB) and low bioavailability restrict its clinical translation. To address these problems, a SalB-loaded liquid crystalline nanoparticle delivery system (SalB-LCN) was constructed and systematically characterized in terms of its physicochemical properties. Meanwhile, an intranasal administration strategy was employed to bypass the BBB, and the therapeutic effects of SalB-LCN on VD were systematically evaluated. The results showed that SalB-LCN possessed favorable morphology and sustained-release properties, enabling stable encapsulation and continuous release of SalB. In vitro experiments demonstrated that SalB-LCN exhibited good biocompatibility and could alleviate oxidative damage in neuronal cells. In a bilateral common carotid artery occlusion-induced rat model of VD, SalB-LCN significantly improved learning and memory abilities, alleviated hippocampal neuronal morphological damage, and exhibited good in vivo biosafety. Further studies showed that SalB-LCN markedly lowered reactive oxygen species levels, suppressed IL-1\u03b2 and IL-18 production in hippocampal tissues, and reduced cell death as well as lactate dehydrogenase activity. In addition, SalB-LCN also suppressed NLRP3/Caspase-1/GSDMD signaling. In conclusion, intranasal delivery of SalB-LCN improved brain delivery by facilitating transport across the BBB and conferred neuroprotection against VD through modulation of oxidative stress, inflammation, and NLRP3/Caspase-1/GSDMD signaling, highlighting its translational potential as a nanomedicine-based therapeutic strategy.\n\nID: 42480526\nTitle: CSF clearance through arachnoid fenestrations to olfactory meningeal lymphatics.\nAbstract: Meningeal (dural) lymphatics are essential for cerebrospinal fluid (CSF) clearance to cervical lymph nodes, yet the precise pathway is incompletely understood. Using a multifaceted approach in mice, we examined tracer dynamics and the CSF outflow pathway from the subarachnoid space (SAS) to the nasal mucosa and identified a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations. Similar arachnoid fenestrations were found in cynomolgus monkeys. Fluorescent tracers in the SAS passed through arachnoid fenestrations into dural lymphatics, which traversed the cribriform plate foramina, joined the nasal lymphatics, and drained to the cervical lymph nodes. In aged mice, the known reduction in CSF outflow was accompanied by lymphatic atrophy in the olfactory dura and nasal mucosa and by fewer arachnoid fenestrations and smaller cribriform plate foramina. Importantly, the lymphatics and CSF clearance were restored to normal by intranasal delivery of vascular endothelial growth factor-C (VEGF-C), thereby documenting the reversibility of the aging-related impairment in CSF clearance.\n\nID: 42428020\nTitle: MERLIN-SUITE: Probabilistic modular GRN inference from multi-omics data integrating regulatory priors and transcription factor activity.\nAbstract: Accurately reconstructing gene regulatory networks (GRNs) is essential for understanding transcriptional processes in development and disease. MERLIN-SUITE (https://github.com/Roy-lab/MERLIN-SUITE) represents a collection of algorithmic extensions based on MERLIN (Modular regulatory network learning with per gene information) a probabilistic framework that infers gene-specific and module-specific regulatory programs of co-regulated modules, capturing both detailed and modular aspects of transcriptional networks. While expression-based inference is effective, it often aligns poorly with experimentally validated regulatory interactions. MERLIN-P addresses this by integrating external regulatory priors, such as motif, ChIP, and perturbation data, to enhance biological relevance and predictive accuracy. MERLIN-P-TFA further advances the framework by incorporating regularized estimation of latent transcription factor activity (TFA), overcoming the limitation that TF mRNA levels may not represent protein activity. By integrating expression data, prior knowledge, and activity-aware modeling, this unified approach supports robust GRN reconstruction in both bulk and single-cell datasets. This chapter presents the MERLIN-SUITE with a focus on MERLIN-P-TFA and demonstrates its use on a single-cell, multi-modal dataset of mouse cellular reprogramming to infer GRNs and identify key regulators.\n\nID: 42399983\nTitle: Regional mapping of CSF1R-positive microglia in neurodegenerative diseases and progressive MS, with exploratory presynaptic marker analyses.\nAbstract: Microglial colony-stimulating factor-1 receptor (CSF1R) is a therapeutic and imaging target, yet the regional, disease-specific distribution of CSF1R-positive microglia in the human brain remains incompletely defined, limiting interpretation of emerging CSF1R-PET signals. We sought to build a cross-disease, multi-region, quantitative map of CSF1R-positive microglia in neurodegenerative conditions and progressive multiple sclerosis (MS) lesions, with an exploratory comparison to presynaptic marker burden. CSF1R mRNA\u2011positive microglia were quantified by RNAscope across six cortical regions (MFG, IFG, ITG, AG, CA1, EC) in early\u2011onset Alzheimer's disease (EOAD), late\u2011onset AD (LOAD), progressive supranuclear palsy (PSP), and frontotemporal lobar degeneration with TDP-43 inclusions due to progranulin mutation (FTLD\u2011GRN), and in primary and secondary progressive MS (PPMS, SPMS) within cortical gray\u2011matter plaques, plaque-adjacent gray matter and white matter. Positivity was defined a priori as\u2009\u2265\u20093 puncta with housekeeping\u2011probe pass and negative\u2011control verification, counting blinded, and densities were cortical\u2011thickness corrected. Iba-1 immunolabeling verified microglial identity. Western blot provided protein\u2011level verification. We explored ROI\u2011level associations of CSF1R with SV2A and synaptophysin previously measured in the same regions/cases. In neurodegeneration, increases were smaller and region\u2011specific (e.g., EOAD-ITG/CA1; LOAD-AG; PSP-AG; FTLD\u2011GRN-IFG/ITG/AG/EC), with minimal white\u2011matter change. In progressive MS, gray-matter CSF1R-positive microglia densities did not differ from controls, whereas SPMS white matter was increased. Exploratory analysis showed that CSF1R and SV2A were positively associated across ROIs in neurodegenerative diseases (e.g., PSP approximately \u03c1\u2009=\u20090.66), and weakest in LOAD; synaptophysin showed similar patterns, suggesting that regions with higher CSF1R-positive microglia density can coincide with relative preservation of presynaptic markers. A cross\u2011disease, region\u2011resolved map reveals region\u2011specific changes in CSF1R\u2009+\u2009cell density in neurodegeneration, but only white matter in MS. These findings provide the histological context needed to interpret future CSF1R\u2011PET. Prospective studies pairing CSF1R\u2011PET with SV2A\u2011PET and multiplex tissue profiling are warranted to define microglial states and synaptic outcomes in vivo.\n\nID: 42311424\nTitle: Engineering Nanocarriers for Dopamine Stabilization and Targeted Brain Delivery: Mechanisms, Approaches and Translational Challenges.\nAbstract: Dopamine plays a central role in motor control, cognition, reward signaling, and neuroendocrine regulation, and its dysregulation is strongly associated with neurological disorders such as Parkinson's disease. However, conventional dopaminergic therapies remain limited by poor blood-brain barrier (BBB) penetration, rapid systemic metabolism, short half-life, peripheral toxicity, and dopamine oxidation-induced neurotoxicity. Nanomedicine-based drug delivery systems have emerged as promising strategies to overcome these limitations by enhancing dopamine stability, improving BBB transport, enabling controlled release, and facilitating targeted delivery to dopaminergic brain regions. This review comprehensively summarizes current advances in dopamine-targeted nanotherapeutics, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, dendrimers, inorganic nanoparticles, exosomes, and biomimetic vesicles. Particular emphasis is placed on the dual role of nanocarriers in both facilitating dopamine delivery and protecting dopamine from oxidative degradation and reactive oxygen species-associated toxicity. Among currently investigated platforms, polymeric nanoparticles, lipid-based nanocarriers, and exosome-inspired vesicles appear particularly promising due to their ability to improve dopamine stability, facilitate controlled release, enhance BBB penetration, and enable targeted brain delivery. The review additionally discusses receptor-mediated targeting strategies, intranasal delivery approaches, translational barriers, manufacturing scalability, long-term safety considerations, and regulatory challenges associated with clinical implementation. Finally, emerging future directions involving AI-assisted nanocarrier engineering, precision-targeted delivery systems, and stimuli-responsive nanomedicine are highlighted as promising approaches for the development of next-generation therapies for neurodegenerative disorders.\n\nID: 42302287\nTitle: Network-based analysis of crucial genes for salt tolerance in rice.\nAbstract: Rice responds to salt stress by modulating a vast array of genes integrated into a sophisticated regulatory network. This complexity makes it challenging to identify the key genes and the specific alleles that confer tolerance. We used time-course expression analysis to profile gene and miRNA expression associated with salt tolerance in Pokkali, a salt-tolerant rice variety. We established a framework for studying transcription factor-target(mRNA/miRNA) interactions using gene co-expression and machine-learning models. Moreover, we developed a hypergeometric distribution-based method to elucidate the interactions of salt stress-related miRNA-targets. Using these approaches, we established co-expression (GCN) and gene regulatory networks (GRN) based on co-expression and TF/miRNA-target interactions. Hub genes with high connectivity in our networks were enriched for previously reported salt tolerance genes, a finding largely supported by subsequent haplotype analysis of 374 rice accessions. Finally, we functionally validated three crucial hub genes, OsCAF1B, OsADR3 and Ospdr9, by demonstrating their roles in salt tolerance using their knockout mutants. The crucial genes, haplotypes and networks for salt tolerance identified in this study (resource available at https://cbi.njau.edu.cn/RiceSALTnet) provide a foundation for breeding rice cultivars with enhanced salt tolerance.\n\nID: 42300978\nTitle: Next-generation intranasal delivery nano-platforms for targeted brain therapy of Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder that poses a growing global health burden. Effective drug delivery to the brain is largely constrained by the selective nature of the blood-brain barrier (BBB), which limits therapeutic efficacy of conventional oral medications. Intranasal administration has emerged as a noninvasive and promising route for direct nose-to-brain transport, circumventing BBB restrictions. This review explores the potential of intranasal drug delivery as an alternative approach for targeted brain therapy in Alzheimer's disease. It comprehensively discusses the mechanisms of nasal absorption, physiological and formulation-related barriers, and the role of advanced nanocarrier platforms in overcoming these limitations. Emphasis is placed on recent innovations involving polymeric, lipid-based, and vesicular carriers, along with the incorporation of mucoadhesive and permeation-enhancing agents. The present focus is enhancing bioavailability, prolonging drug residence time, and minimizing systemic toxicity. Surface modifications of nanocarriers further facilitates mucosal adhesion and enables effective nose-to-brain transport of encapsulated therapeutic agents. However, clinical translation remains challenging due to interindividual variability in nasal physiology, scalability constraints, and regulatory complexities. Future progress will depend on the rational design of multifunctional nanocarriers, integration of mucoadhesive and stimuli-responsive components, and the use of precision-based formulation strategies.\n\nID: 42242508\nTitle: In situ nasal gel loaded with Lactoferrin-Coated Brexpiprazole nanostructured lipid carriers for Schizophrenia: Cross-Species validation in Ketamine-Induced rat and zebrafish models.\nAbstract: Brexpiprazole (BXP), a third-generation antipsychotic, exhibits limited brain delivery following oral administration due to first-pass metabolism and blood-brain barrier constraints. To overcome these limitations, a Lactoferrin (Lf)-functionalized BXP-loaded nanostructured lipid carrier (Lf-BXP-NLC) incorporated into a thermoresponsive in situ nasal gel was developed to enable sustained and receptor-mediated nose-to-brain transport. The optimized formulation demonstrated nanoscale particle size (<200\u00a0nm), narrow polydispersity, high entrapment efficiency (\u223c88%), and physiological gelation temperature (30-34\u00a0\u00b0C), with preserved physicochemical stability over 3\u00a0months. In vitro release and ex vivo permeation studies confirmed controlled drug release and enhanced mucosal transport. In vivo pharmacokinetic evaluation in rats revealed significantly improved brain exposure following intranasal administration, with approximately 1.9-fold higher AUCbrain compared with drug suspension and 1.97-fold greater exposure relative to intravenous delivery. A rapid brain Tmax (0.41\u00a0h) and direct transport percentage of\u00a0\u223c\u00a062% indicated dominant neuronal pathway involvement and reduced reliance on systemic circulation. Enhanced pharmacokinetics translated into pronounced pharmacodynamic benefits in ketamine-induced schizophrenia models, including significant attenuation of stereotypic behaviors, restoration of motor coordination, and near-normalization of neuromuscular performance. Cross-species validation in zebrafish further demonstrated substantial correction of anxiety-like behavior and cognitive impairment, reinforcing translational robustness. Importantly, no nasal ciliotoxicity was observed. Collectively, this multifunctional intranasal nanocarrier platform achieves rapid, sustained, and targeted brain delivery of BXP and offers a promising non-invasive strategy for precision neuropsychiatric therapy.\n\nID: 42163770\nTitle: ChEA-KG and ChEA-KG-TS: a network-based transcription factor enrichment analysis tool with an accompanying time-series workflow.\nAbstract: Transcription factor (TF) modules interact to regulate key biological processes and cell-state transitions in normal physiology and disease. Understanding these modules and how they evolve over time can be accomplished by constructing gene regulatory networks (GRNs). To identify context-specific TF subnetworks, we developed ChEA-KG, which generates enriched TF regulatory subnetworks for input gene sets. ChEA-KG is based on a GRN connecting 1559 human TFs via 131\u2009181 signed and directed edges inferred from diverse published ChIP-seq (chromatin immunoprecipitation followed by sequencing) and mRNA (messenger RNA)-sequencing experiments. We demonstrate ChEA-KG's utility by applying it to uncover master regulators of aging, mechanisms of action (MoA) for drug classes, pan-cancer subtypes, and cell types from across 14 major human tissues. Next, we extend ChEA-KG to develop the webserver application ChEA-KG Time Series (ChEA-KG-TS), which identifies TF modules from time-series mRNA-sequencing datasets. Results from this workflow are automatically summarized as reports that include enrichment analysis, regulatory subnetworks, and UMAP projections of enriched TFs. We use ChEA-KG-TS to explain transient responses in two use cases. ChEA-KG and ChEA-KG-TS are available from\u00a0https://chea-kg.maayanlab.cloud/ and https://chea-kg-ts.maayanlab.cloud/.\n\nID: 42076632\nTitle: Advanced Sensing and Delivery Technologies for Nose-to-Brain Administration: From Nanocarriers to Sensor-Integrated Organ-on-Chips.\nAbstract: Central nervous system (CNS) disorders represent a growing healthcare burden, and various drugs are developed for their treatment. However, the blood-brain barrier (BBB) prevents over 98% of therapeutics from reaching brain tissue. Intranasal delivery provides a promising alternative by exploiting olfactory and trigeminal nerve pathways to circumvent the BBB. This review surveys recent advances in nose-to-brain delivery technologies, from carrier design to evaluation methods. Polymeric and lipid-based nanocarriers show enhanced mucosal penetration and prolonged residence time, and microneedle platforms further enable controlled drug release with minimal discomfort. To evaluate these delivery strategies, sensor-integrated organ-on-chip models provide more physiologically relevant testing than static cultures. Although persistent challenges such as rapid mucociliary clearance and formulation stability remain, combining nanotechnology with microfluidic devices and computational modeling shows potential for developing patient-specific therapeutics.\n\nID: 42034268\nTitle: Precision nose-to-brain therapeutics: Advances in drug delivery systems and emerging preclinical models.\nAbstract: Intranasal administration has emerged as a promising non-invasive route for brain-targeted drug delivery, primarily due to its unique ability to bypass the blood-brain barrier (BBB) and facilitate direct brain targeting via neural pathways. Consequently, this route has been extensively investigated for treating diverse brain disorders, ranging from acute conditions to neurodegenerative diseases. Despite the advantages and clinical approval of several nasal products, the need for effective disease-modifying therapies (DMTs) of brain disorders remains unmet. Given that most brain disorders involve region-specific or cell-type-specific pathological changes, and that off-target effects may result in central nervous system toxicity, precision nose-to-brain delivery is critical. A major challenge to its clinical translation remains the lack of predictive, human-relevant preclinical models. Therefore, this review explores the challenges in nose-to-brain drug delivery development, highlights advanced intranasal delivery strategies for treating brain disorders, and discusses emerging in vitro models for evaluating nose-to-brain delivery efficiency. The work aims to promote the development and clinical translation of intranasal brain-targeted therapeutics.\n\nID: 42024000\nTitle: Chitosan-Based Nanoparticles for Nose-to-Brain Drug Delivery: A Real Path toward Effective CNS Therapy?\nAbstract: Treating central nervous system (CNS) disorders remains a major clinical challenge. The blood-brain barrier (BBB), systemic toxicity, and first-pass metabolism are key obstacles. These factors limit the effective drug delivery to the brain. Intranasal administration has emerged as a noninvasive strategy to bypass the BBB. This approach enables direct drug delivery to the brain through the olfactory and trigeminal nerve pathways, commonly referred to as nose-to-brain (N2B) delivery. In this context, chitosan (CS), a biocompatible and mucoadhesive polysaccharide with permeation-enhancing properties, has gained significant interest as a functional material for nanoparticle (NP) engineering. CS-based or CS-coated NP can prolong the residence time on the nasal mucosa and facilitate drug transport to the CNS. This review provides a comprehensive overview of recent advances in CS-based NP for N2B drug delivery across a range of CNS disorders, including neurodegenerative, neuropsychiatric, neoplastic, and infectious conditions. Particular attention is given to formulation strategies, mechanistic insights, and preclinical outcomes. Recent patent applications are surveyed to underscore the translational potential and commercial interest in this technology. Collectively, CS-based NPs effectively address major therapeutic barriers, establishing a transformative and innovative platform in CNS drug delivery.\n\nID: 42012729\nTitle: Spermidine in the aging brain: mechanisms, preclinical evidence, and clinical perspectives.\nAbstract: Spermidine, a naturally occurring polyamine, has emerged as a candidate modulator of brain aging because it regulates autophagy, mitochondrial function, oxidative balance, and neuroinflammatory signaling. This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations.\n\nID: 41875607\nTitle: Nose-to-brain delivery of berberine-loaded nanoemulsion: Amelioration of brain targeting, behavioral, pharmacokinetic, and biodistribution insights for Alzheimer's intervention.\nAbstract: Berberine (BER), a benzylisoquinoline alkaloid, has garnered attention for its multifaceted pharmacological properties, including pronounced antioxidant, anti-inflammatory, and neuroprotective effects. Despite its therapeutic potential in neurodegenerative disorders, including Parkinson's disease, cerebral ischemia, and epilepsy, its clinical translation in Alzheimer's disease (AD) is hindered by poor aqueous solubility, limited systemic bioavailability, and restricted blood-brain barrier (BBB) permeability. This study aimed to overcome these limitations by formulating a BER-loaded nanoemulsion (BER-NE) for intranasal (IN) delivery to achieve direct nose-to-brain (N2B) targeting. The optimized NE exhibited a droplet size of 138.5\u00a0\u00b1\u00a00.96\u00a0nm and a polydispersity index (PDI) of 0.203\u00a0\u00b1\u00a00.007, indicating a monodisperse system. The BER-NE demonstrated a drug content of 99.62\u00a0\u00b1\u00a01.02%, confirming efficient drug incorporation. In vitro studies on SH-SY5Y neuroblastoma cells demonstrated that BER-NE reduced reactive oxygen species (ROS) levels by 2.09-fold and restored mitochondrial membrane potential (MMP) with a 3.61-fold increase in red/green fluorescence intensity compared to SCOP-induced cells. Further, pharmacokinetic (PK) profiling revealed that IN BER-NE achieved a 3.2- and 3.6-fold increase in brain Cmax compared to BER-SUS IN and BER-NE IV, respectively. The IN BER-NE demonstrated a 1.7- and 1.9-fold increase in %DTE and %DTP compared to the IN SUS, which supports the efficient N2B delivery. Behavioral assessments demonstrated dose-dependent reversal of SCOP-induced cognitive, depressive, and motor impairments. Additionally, treatment with HD BER-NE and MD BER-NE via the IN route markedly reduced the nitrite accumulation by 4.3- and 3.5-fold compared to the SCOP group, indicating attenuation of nitrosative stress. Collectively, these findings underscore the potential of IN BER-NE as a targeted and non-invasive therapeutic strategy for the management of AD.\n\nID: 41873359\nTitle: Intranasal Nano-Delivery Systems: Emerging Strategies for Central Nervous System Disease Therapeutics.\nAbstract: The rising global incidence of central nervous system (CNS) diseases, exacerbated by the formidable blood-brain barrier (BBB) hindering effective drug delivery, necessitates novel therapeutic strategies. Nasal administration has emerged as a promising non-invasive route, bypassing the BBB via direct neural pathways (olfactory/trigeminal), systemic absorption, or lymphatic drainage. However, inherent nasal barriers like the mucus layer and epithelium limit its efficacy. This review distinguishes itself by integrating mechanistic insights into nasal transport pathways with the rational design of advanced nano-delivery systems. We first outline the challenges in CNS drug delivery and detail the nasal anatomy and transport pathways facilitating nose-to-brain delivery. Subsequently, we emphasize the critical properties required of advanced nano-carriers to improve mucosal penetration, prolong retention, and promote drug accumulation at cerebral injury sites. Following a detailed analysis of the advantages and limitations associated with nose-to-brain delivery, we consolidate recent advances in nasal nano-delivery systems for treating CNS disorders, emphasizing their capacity to improve brain-targeting efficiency, enhance therapeutic efficacy, reduce systemic toxicity, and enable previously undruggable CNS targets. Finally, we expand the discussion to encompass current challenges impeding clinical translation, including safety concerns, manufacturing scalability, and regulatory hurdles, while highlighting emerging trends such as artificial intelligence-driven formulation design. This comprehensive analysis aims to deepen the understanding of nasal-to-brain transport mechanisms and inform the future development of effective nasal formulations for improved neurological therapeutics.\n\nID: 41868129\nTitle: IncRNAs transcriptomics elucidates the potential mechanism of Naoshuantong capsule in alleviating synaptic dysfunction in a murine model of cerebral ischemia/reperfusion injury.\nAbstract: Naoshuantong capsule (NST), a Traditional Chinese Medicine formulation, is used for ischemic stroke treatment; however, its molecular mechanisms are unclear. This study aimed to investigate the mechanistic basis of NST using long noncoding RNA (lncRNA) and messenger RNA (mRNA) transcriptomics. The metabolites of NST were analyzed. Additionally, its systemically absorbed metabolites (in plasma) and brain-distributed metabolites were identified using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The therapeutic effects of NST were evaluated in a mouse model of middle cerebral artery occlusion (MCAO) using neurological scoring, behavioral testing, cerebral blood flow, and brain tissue staining. LncRNA and mRNA expression profiles were analyzed using the Agilent Mouse competing endogenous RNA microarray, followed by gene ontology and Kyoto encyclopedia of genes and genomes enrichment analyses. Differentially expressed transcripts were validated using quantitative reverse transcription polymerase chain reaction (qRT-PCR). UHPLC-MS/MS analysis detected 129 metabolites in NST; 33 metabolites in plasma; and 17 metabolites in brain tissue of rats administered with NST. NST treatment significantly reduced neurological deficit scores (Longa score), decreased beam-crossing latency, and increased forelimb grip strength in middle MCAO mice, indicating improved neurological function. Additionally, NST treatment enhanced cerebral blood flow recovery, ameliorated pathological damage, restored neuronal architecture, and increased Nissl-stained neuron density in peri-infarct brain tissue. NST also attenuated cellular apoptosis by upregulating Bcl-2 expression and downregulating Bax protein levels, exerting neuroprotective effects. Notably, NST treatment reversed 177 out of 5,378 differentially expressed IncRNAs and 52 out of 5,540 differentially expressed mRNAs that were dysregulated between the model and sham groups. These NST-modulated IncRNAs participate in key biological processes, including synaptic modulation, apoptosis regulation, and neuronal function. A synaptic plasticity-associated lncRNA-mRNA coexpression network was developed using NST-reversed transcripts. Validation using qRT-PCR confirmed the upregulation of NONMMUT050688.2 and NONMMUT044667.2, and the downregulation of NONMMUT092269.1 and NONMMUT101071.1, the downregulation of Nrn1, the upregulation of Grn, and the downward trend in Rasd2 expression in MCAO mice. All these alterations were reversed through NST treatment. In vivo experiments confirmed the efficacy of NST in ameliorating memory deficits, mitigating synaptic structural damage, and upregulating key synaptic protein expression (SYN and PSD95) in mice. NST may protect against cerebral ischemia/reperfusion injury by modulating lncRNA and mRNA expressions to enhance synaptic plasticity, thereby preserving neuronal structure and function.\n\nID: 41828589\nTitle: From Polyphenols to Prodrugs: Bridging the Blood-Brain Barrier with Nanomedicine and Neurotherapeutics.\nAbstract: Central nervous system disorders drive disability, yet many neuroactive candidates fail because the brain is a hard compartment to dose. Plant-derived molecules spanning polyphenols, alkaloids, terpenoids, and cannabinoids are attractive because their pleiotropic actions can engage oxidative stress, neuroinflammation, and circuit dysfunction. In practice, the blood-brain barrier (BBB) restricts most native phytochemicals through tight-junction selectivity, rapid metabolism, low solubility, and transporter-mediated efflux. Key gaps include poor standardization of exposure metrics, limited human-relevant BBB models, and few head-to-head studies that compare delivery platforms on the same payload and outcome. This review tackles the mismatch between mechanistic promise and reliable brain exposure that stalls translation. The objectives are to link phytochemical liabilities to enabling strategies in nanomedicine, alternative routes, and transporter-targeted prodrugs, and to propose decision-grade endpoints for translation. We synthesize evidence on BBB transport logic, nanocarrier families, targeting ligands, intranasal delivery, focused ultrasound-mediated opening, and prodrug approaches that hijack influx transporters, while foregrounding safety and chemistry, manufacturing, and controls (CMC) constraints. Here we highlight that effective neurotherapeutics emerge when chemistry, carrier, route, and measurement are co-designed rather than optimized in isolation. This framework can guide platform selection, de-risk first in-human studies, and sharpen trial endpoints. More broadly, it offers a transferable playbook for barrier-limited drug development across neurology, psychiatry, and oncology.\n\nID: 41820617\nTitle: ZAP targets aberrant mRNA transcripts encoding proteins with defective signal peptides for degradation.\nAbstract: The endoplasmic reticulum (ER) is an important site for accurate folding and processing of secretory and membrane proteins. Signal peptides within such proteins are recognized by the signal recognition particle (SRP), which guides them to the ER. When this process is impaired, cells rely on quality control mechanisms to prevent the accumulation of misfolded or mislocalized proteins. One of these mechanisms, known as regulation of aberrant protein production (RAPP), detects nascent proteins with aberrant signal peptides and degrades their mRNA templates. Using functional genetic screens, we identify the zinc finger antiviral protein (ZAP) as a key component of the RAPP pathway. Proteomics and enhanced UV-crosslinking and immunoprecipitation (eCLIP) experiments reveal that the short isoform ZAP-S associates with SRP components and facilitates degradation of aberrant mRNAs. ZAP-S recognizes faulty proteins early in their biogenesis and targets their corresponding mRNAs for degradation. Loss of ZAP activates the unfolded protein response and the downstream integrated stress response, highlighting its central role in safeguarding protein targeting and maintaining cellular homeostasis.\n\nID: 42534522\nTitle: Ginseng-derived exosomes loaded in fibrin gel promote retinal ganglion cell survival in glaucoma by exerting anti-inflammatory effects through modulating microglial polarization.\nAbstract: Glaucoma is the leading cause of irreversible blindness globally. Chronic neuroinflammation drives progressive retinal ganglion cell (RGC) loss independent of intraocular pressure, yet safe, sustained and precise neuroprotective modulation of the retinal inflammatory microenvironment remains a significant challenge. We developed an injectable fibrin gel delivery system loaded with ginseng-derived exosomes (GE-fibrin gel, GE-gel) to modulate microglial polarization, reduce retinal inflammation and promote RGC survival. In vitro, GE showed strong antioxidant and anti-apoptotic effects by getting rid of reactive oxygen species caused by oxidative stress and lowering apoptosis in R28 cells. Both GE and GE-gel stopped lipopolysaccharide from causing pro-inflammatory M1 polarization of microglia and increased anti-inflammatory M2 phenotypic change. Intravitreal injection of GE-gel suppressed pro-inflammatory microglial activation, diminished neuroinflammation and improved the survival of RGCs in a chronic ocular hypertension rat model. These results show that GE-gel could promote microglial polarization, change the immune environment in the retina and protect RGCs functionally over the long term. This approach may hopefully provide promising solutions for rapid and effective glaucoma therapy.\n\nID: 42501555\nTitle: Gut microbiota and polycystic ovary syndrome: Pathogenesis and novel therapeutic approaches.\nAbstract: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women that is characterized by a complex pathogenesis involving multiple mechanisms, including hyperandrogenism, ovulatory dysfunction, insulin resistance (IR), and chronic inflammation. Recent studies have demonstrated that the gut microbiota acts as an important metabolic regulator and may play a pivotal role in the onset and progression of PCOS. Patients with PCOS frequently exhibit gut microbiota dysbiosis, which is characterized by reduced microbial diversity, decreased levels of beneficial bacteria, increased levels of pathogenic bacteria, and altered metabolic byproducts. This imbalance may contribute to IR and ovarian dysfunction by activating the toll-like receptor 4/nuclear factor kappa B inflammatory pathway, inducing oxidative stress, and disrupting Wnt/\u03b2-catenin signaling. The Wnt/\u03b2-catenin signaling pathway, a key regulator of follicular development, is frequently aberrantly activated in PCOS. In this narrative review, we summarize the recent advances in understanding the roles of the gut microbiota and the Wnt/\u03b2-catenin signaling pathway in the pathogenesis of PCOS. To this end, we conducted a comprehensive literature search across PubMed, Web of Science, Embase, and Cochrane Library databases, covering publications from January 2012 to March 2026. Ninety-eight articles were included after screening. We further explored therapeutic strategies based on microbiome modulation and signaling pathway targeting, including probiotics, traditional Chinese medicine, ginsenosides, puerarin, fecal microbiota transplantation, and nanoparticle-based ginseng-derived exosomes, thereby providing novel insights into potential therapies for PCOS.\n\nID: 42098749\nTitle: Research progress on the mechanisms of Panax ginseng and its active components in maintaining skin homeostasis and disease intervention.\nAbstract: Panax ginseng (Panax ginseng C.A. Meyer) is a classic herbal medicine widely utilized in dermatological management, yet its precise therapeutic mechanisms have only recently begun to be fully elucidated. This review systematically synthesizes the pharmacological roles of ginseng's active components, including ginsenosides, polysaccharides, and gintonin, in maintaining skin homeostasis and treating various cutaneous pathologies. Emerging evidence suggests that the efficacy of ginseng extends beyond direct molecular interactions, exhibiting the distinct characteristics of \"indirect pharmacology.\" Specifically, parent ginsenosides function primarily as natural prodrugs that require microbial biotransformation into high-affinity active metabolites, such as Compound K and Rh2, to exert potent therapeutic effects. Functionally, these components regulate skin health by mobilizing endogenous host defense systems, particularly through the activation of the Nrf2/ARE antioxidant pathway and the suppression of inflammatory cascades via the NF-\u03baB, MAPK, and IL-1 signaling networks. Furthermore, they remodel the systemic microenvironment through the gut-skin axis, facilitating metabolic homeostasis to improve skin barrier function. Notably, biotransformation rates and ultimate therapeutic efficacy are highly dependent on individualized variables, such as host age, dietary patterns, and baseline disease states. This systemic regulation has demonstrated robust efficacy in intervening in complex pathologies, including atopic dermatitis, psoriasis, and skin cancer. Additionally, this article addresses the translational bottleneck of low bioavailability and evaluates recent advances in novel skin delivery systems, specifically those utilizing ginseng-derived exosomes. Collectively, this review provides a scientific framework for understanding the systemic actions of ginseng, supporting its development as a precision botanical therapy for dermatological applications.\n\nID: 42090956\nTitle: Panax notoginseng-derived extracellular vesicles alleviate doxorubicin-induced cardiotoxicity by suppressing p53 activation.\nAbstract: Doxorubicin (Dox) is a highly effective chemotherapeutic agent, but its clinical use is limited by cumulative cardiotoxicity. Panax notoginseng, a traditional medicinal herb, exhibits well-documented cardioprotective properties; however, the therapeutic application of its bioactive constituents is constrained by poor bioavailability and potential toxicity. Plant-derived extracellular vesicles (EVs) have emerged as natural nanocarriers facilitating cross-kingdom delivery of bioactive metabolites. In this study, we investigated whether P. notoginseng-derived EVs (PEVs) could mitigate Dox-induced cardiotoxicity (DIC) and explored the underlying mechanisms. PEVs were isolated from P. notoginseng rhizomes and systematically characterized, with metabolite profiling performed by UPLC-MS. Cellular uptake, biodistribution, and cardioprotective effects were evaluated in Dox-injured cardiomyocytes and a chronic mouse model of DIC. Mechanistic insights were obtained using transcriptomic analysis, molecular docking, and biochemical assays. PEVs were stable nanosized vesicles enriched with characteristic P. notoginseng metabolites, including triterpenoid saponins and dencichine. PEVs were efficiently internalized by cardiomyocytes and preferentially accumulated in injured myocardium. Functionally, PEVs attenuated Dox-induced inflammation, apoptosis, myocardial atrophy, fibrosis, and cardiac dysfunction, with efficacy comparable to dexrazoxane. Mechanistically, transcriptomic and molecular analysis identified p53 as a central regulatory target. PEVs-derived metabolites targeted the p53 DNA-binding domain, suppressing p53 phosphorylation and transcriptional activation of pro-apoptotic and inflammatory genes. Notably, p53 activation attenuated PEVs-mediated protection, whereas p53 inhibition or silencing abolished additional protective effects, indicating a p53-dependent mechanism. PEVs protect against DIC by delivering bioactive metabolites to injured myocardium and inhibiting p53-driven oxidative, inflammatory, and apoptotic pathways, highlighting their potential as a phytomedicine-based cardioprotective strategy.\n\nID: 41798903\nTitle: Erratum: Ginseng-Derived Exosomes Attenuate Immune Evasion in NSCLC via PD-L1 Modulation [Corrigendum].\nAbstract: [This corrects the article DOI: 10.2147/CMAR.S540462.].\n\nID: 41772638\nTitle: Synergistic delivery of ginseng exosomes and biomimetic melanosomes via temporally controlled hydrogel microneedles restrain the pathologic triad of vitiligo.\nAbstract: Vitiligo pathogenesis involves progressive melanocyte loss and keratinocyte dysfunction, which are driven primarily by oxidative stress resulting from excessive ROS accumulation. We engineered a temporally controlled hydrogel microneedle system that integrates ginseng-derived exosomes (G-Exos) with biomimetic polydopamine nanoparticles (PDA@PEGs) to concurrently target the pathogenic triad of vitiligo, including oxidative stress, inflammation, and melanocyte deficiency. This system employs methacrylated hyaluronic acid (HAMA) hydrogel microneedles for rapid PDA@PEG release while utilizing glyceryl monostearate micelles to achieve matrix metalloproteinase-9 (MMP-9)-responsive G-Exo release at inflammatory foci, enabling intelligent spatiotemporal control. Functionally, G-Exos help restore redox homeostasis and suppress inflammation through bioactive constituents, thereby protecting melanocytes and enhancing keratinocyte proliferation. Moreover, PDA@PEG promotes repigmentation through the dual mechanisms of exogenous melanin deposition and endogenous melanogenesis stimulation. In murine models, this strategy achieves significant repigmentation within 3 weeks by activating follicular stem cells, upregulating melanogenic markers (Tyr/Mc1r), increasing antioxidant defense (ApoE), and suppressing inflammatory signaling (IL-17). This natural-biomimetic hybrid design leverages biocompatible materials to co-target multiple pathological axes, offering a novel self-adaptive approach for microenvironmental rehabilitation in vitiligo.\n\nID: 41628353\nTitle: Ginseng-Derived Exosomes-Loaded Thermosensitive Hydrogel for the Treatment of Periodontitis.\nAbstract: Periodontitis represents a persistent inflammatory condition marked by the irreversible destruction of the alveolar bone, eventually leading to tooth loss. The ideal treatment for periodontitis involves three key steps: antibacterial treatment, inflammation control, and periodontal regeneration, ultimately leading to the complete restoration of alveolar bone and the full recovery of periodontal function. However, current periodontitis treatments cannot comprehensively solve these issues. In this study, a ginseng-derived exosomes (GEXs)-loaded injectable hydrogel (GEXs@Gel) was designed. GEXs@Gel was thermosensitive with good fluidity, capable of conforming to the intricate contours of periodontal pockets, while withstanding the persistent wash of gingival crevicular fluid. In vitro studies showed that GEXs and GEXs@Gel can inhibit the growth of periodontal pathogenic bacteria, effectively remove biofilms, promote the polarization of macrophages to the anti-inflammatory (M2) phenotype, and alleviate cellular oxidative stress. In particular, GEXs@Gel had the functions of promoting bone/angiogenesis and regeneration. In vivo studies showed that GEXs@Gel effectively inhibited inflammation, promoted alveolar bone regeneration, and effectively reversed periodontitis. In summary, GEXs@Gel offers a promising strategy for the treatment of periodontitis.\n\nID: 41560797\nTitle: Targeting single-cell multiomics-identified vascular impairment: Panax notoginseng extracellular vesicles-loaded adhesive QBK-2/EVs promotes angiogenesis in diabetic wound healing.\nAbstract: Diabetic skin wounds, a severe complication affecting over 18.6 million people globally, are characterized by high amputation and mortality rates. However, the cellular heterogeneity of diabetic wounds and the specific molecular mechanisms underlying their impaired healing remain unclear. Furthermore, treatment strategies based on medicinal plants targeting these pathological mechanisms are lacking. This study explored diabetic wound pathogenesis using single-cell RNA sequencing (scRNA-seq), revealing a 52\u00a0% reduction in vascular endothelial cells (ECs) and a decreased abundance of proliferative ECs in diabetic wound tissues, which contributed to impaired vascular repair. Network pharmacology and RT-qPCR identified E-selectin (SELE) as the key target of Panax notoginseng in the treatment of diabetic wounds, which was corroborated by molecular docking. Plant-derived extracellular vesicles (EVs) represent a class of superior bioactive nanomaterials compared to traditional extracts, exhibiting high delivery efficiency, molecular transport capacity, and biocompatibility, enabling cross-species communication essential for therapeutic applications. To further overcome limitations associated with plant-derived extracts (e.g., short half-life), we isolated Panax notoginseng EVs and subsequently loaded them into a hydrogel via dynamic borate ester bonds formed between quaternized chitosan-phenylboronic acid (QCS-BA) and konjac glucomannan (KGM), ultimately generating the QBK-2/EVs composite system. This hydrogel not only effectively encapsulated and continuously released EVs, but also exhibited good injectability, self-healing property, tissue adhesion (42.83\u00a0kPa), and ROS/pH-responsive degradation. In vitro, QBK-2/EVs enhanced human umbilical vein endothelial cell proliferation, migration, and tube formation by downregulating SELE and upregulating angiogenesis markers (CD31, F-actin). In vivo, QBK-2/EVs accelerated wound healing in diabetic mice, promoted hemostasis, increased collagen deposition, and enhanced microvessel density (CD31), while simultaneously reducing the expression of SELE. Overall, this work establishes a mechanism-driven strategy for diabetic wound treatment through synergistic exosome-mediated angiogenesis and hydrogel-based delivery.\n\nID: 41507517\nTitle: Anti-obesity Effects of Panax ginseng-derived exosomes via AMPK-mediated inhibition of adipocyte differentiation and lipogenesis.\nAbstract: This study investigated the anti-obesity potential of Panax ginseng-derived exosomes (PGE) by evaluating their influence on energy metabolism, adipogenesis, and lipid accumulation. PGEs were isolated using a tangential flow filtration system, yielding particles with an average diameter of 159.5\u00a0nm and a concentration of 3.9\u2009\u00d7\u20091012 particles/mL. In 3T3-L1 preadipocytes, PGE treatment resulted in a 72.1% reduction in lipid accumulation, as demonstrated by Oil Red O staining, indicating significant inhibition of adipogenic differentiation. Elevated expression of surface markers TET-8 (147.2%) verified the exosomal nature of the isolated vesicles. To determine their role in adipocyte differentiation, we analyzed gene and protein expression of key adipogenic markers-peroxisome proliferator-activated receptor gamma (PPAR-\u03b3), CCAAT/enhancer-binding protein alpha and beta, and fatty acid-binding protein 4-revealing reductions of 23.6-35.6% and 26.7-35.2%, respectively. These results indicate downregulation of transcriptional and translational pathways driving adipogenesis. Lipogenic regulators, including sterol regulatory element-binding protein 1c, acetyl-CoA carboxylase, and fatty acid synthase, were also suppressed by 24.9-41.0% (gene) and 22.8-24.5% (protein), indicating impaired fatty acid synthesis. Conversely, AMP-activated protein kinase (AMPK) expression increased by up to 53.8% (gene) and 47.9% (protein), implying activation of energy homeostasis signaling. Immunofluorescence analysis showed a reduction in the MitoTracker/DAPI ratio (57.7-60.0%) and an increase in the F-actin/DAPI ratio (39.5-60.8%), indicating decreased mitochondrial activity and enhanced cytoskeletal integrity. These molecular changes were accompanied by AMPK activation and PPAR-\u03b3 inhibition. Collectively, these findings underscore the potential of PGEs as bioactive agents for obesity management by concurrently inhibiting adipogenesis and lipogenesis, providing a strong basis for their application in anti-obesity functional foods and pharmaceutical products.\n\nID: 41491215\nTitle: Endothelial-targeted modification of ginseng-derived exosomes for IL-6 SiRNA delivery ameliorates hepatic ischemia-reperfusion injury.\nAbstract: Liver ischemia-reperfusion injury (IRI) serves as a critical pathological basis for post-hepatectomy liver failure and graft dysfunction following liver transplantation. Excessive inflammatory responses, oxidative stress, and cell death are key mechanisms underlying IRI. The lack of multi-targeted therapies contributes to the current insufficiency in clinical IRI management. This study developed endothelial-targeting VHPKQHR peptide (VHP)-modified ginseng-derived exosomes (G-Exos) loaded with IL-6 small interfering RNA (Si-IL6) (siRNA@VG-Exos) to mitigate liver IRI. VHP modification facilitated the targeted delivery of siRNA@VG-Exos to damaged endothelium, promoting their accumulation and subsequent release at the IRI site. siRNA@VG-Exos effectively reduced hepatic inflammatory cytokine release, enhanced T-SOD and CAT expression while suppressing MDA generation, thereby alleviating oxidative stress. Furthermore, they promoted the restoration of mitochondrial membrane potential, maintaining mitochondrial homeostasis. Si-IL6 additionally suppressed IL-6 expression in liver tissue, synergistically enhancing the anti-inflammatory effect of G-Exos. Moreover, siRNA@VG-Exos inhibited CD86 expression and promoted CD206 expression in hepatic macrophages, facilitating their polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype and modulating immunity. Ultimately, siRNA@VG-Exos reduced hepatic necrotic areas, lowered ALT and AST levels, and restored liver tissue function. Further sequencing analysis indicated that siRNA@VG-Exos alleviates liver IRI by inhibiting immune and inflammatory responses and oxidative stress damage. Therefore, siRNA@VG-Exos provides a novel targeted strategy for the treatment of liver IRI.\n\nID: 41482856\nTitle: Nose to Brain Delivery of Curcumin Loaded Therapeutic Nanostructures for Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases are progressive disorders that damage and eventually kill neurons in the central nervous system (CNS). In recent years, various research has been done on reliable and effective treatment methods for the most common neurodegenerative diseases such as Parkinson's, Alzheimer, and Migraine diseases. Different neurodegenerative disorders such as Huntington's disease, Alzheimer's disease, Parkinson's disease, amyotrophic, Lewy body disease can be treated by curcumin, which is a strong antioxidant polyphenol with neuroprotective and anti-amyloid properties. However, Blood-brain barrier (BBB) and blood cerebrospinal fluid barrier restricts the permeation of curcumin to the brain leads poor distribution of the drug in brain tissue. The intranasal pathway holds promise for enhancing the treatment of CNS disorders since it bypasses the BBB and increases the brain bioavailability of drug. As nanotechnology continues to improve, research on the delivery of drug through intranasal route has grown significantly in last 10 years. Several nanocarriers have been developed such as nano-emulsions, microspheres, dendrimers, liposomes, carbon-based nanoformulation, and nanoparticles to deliver curcumin to the brain via intranasal route for the treatment of neurodegenerative diseases. This study provided a thorough analysis of several curcumin nano-formulations used in intranasal pathway as a novel treatment for neurodegenerative diseases.\n\nID: 41360253\nTitle: An EGCG-enhanced pH/ROS dual-responsive hyaluronic acid hydrogel loaded with ginseng-derived exosomes for diabetic oral ulcers treatment.\nAbstract: Oral ulcers (OU) are prone to recurrence, and are often manifested by the accompanying bacterial infections which may induce a vicious cycle of oxidative stress and inflammatory responses. Traditional treatment methods have limited effects, including being eliminated in the moist and dynamic environment of the mouth, and are prone to various side effects or the development of drug resistance. In this study, we designed borate ester-based and Schiff base-cross-linked hydrogel (OPEC), and loaded ginseng-derived exosome (GEX@OPEC) for the treatment of OU. OPEC hydrogel is composed of phenylboronic acid-functionalized hyaluronic acid oxide (OHA-PBA), epigallocatechin gallate (EGCG), and carboxymethyl chitosan (CMCS). The addition of EGCG enhances its borate cross-linking network and improves the adhesion of the hydrogel. GEX is connected to OPEC through hydrogen bonds and loaded into the hydrogel, further enhancing its gel network. GEX@OPEC exhibited excellent biocompatibility and degradability, ensuring safe oral use of the hydrogel. GEX@OPEC can release EGCG and GEX in response to pH and ROS to exert therapeutic effects. Our research results showed that GEX@OPEC had excellent antibacterial properties, anti-inflammatory and antioxidant stress effects, as well as angiogenic properties, which can effectively promote the healing of OU in diabetic rat models simulating OU. To sum up, GEX@OPEC has good application prospects in the treatment of diabetic OU.\n\nID: 40916157\nTitle: Novel Copper Superparticle-Based Bragg Scattering Coupling Luminescence Strategy for Detection of Ginseng Exosomal miRNA.\nAbstract: Ginseng exosomes are a kind of promising extracellular vesicle containing unique bioactive components. However, the investigation on ginseng-derived exosomes is still in the initial stage. This study developed a photonic crystal-based Bragg scattering coupling electrochemiluminescence (BSC-ECL) biosensor for detection of miRNA396a-3p in exosome-like nanoparticles (GENs) and ginseng exosomes (Gexos). First, copper nanoclusters were engineered into Cu superparticles with \u03c0-\u03c0 stacking of 2,6-dimethylbenzenethiol ligands via a ligand-mediated self-assembly strategy. The prepared Cu superparticles with significantly enhanced luminescence intensity and stability can be used as a nanoprobe. Furthermore, the Bragg scattering law was utilized to modulate the ECL intensity of the Cu superparticles. Due to the highly periodic structure of MIL-96-based photonic crystals, multiple scattering pathways in photonic crystals greatly increased the effective photon flux of Cu superparticles, thus creating a positive feedback loop between photon absorption and emission. Therefore, this cascade amplification mechanism ultimately led to significant BSC-ECL enhancement. The BSC-ECL provided a new quantitative analysis method for key miRNA detection in plant extracellular vesicles, which revealed distinct miRNA concentrations in GENs and Gexos. The method also demonstrated considerable potential in areas such as ginseng quality control, product development, and bioanalysis applications.\n\nID: 40730695\nTitle: Intranasal delivery route for neurodegenerative diseases: recent insights and future directions.\nAbstract: Neurodegenerative diseases are increasingly significant causes of mortality and morbidity worldwide, particularly among the elderly. Despite their widespread prevalence, effective treatment options remain inadequate. A significant challenge contributing to this therapeutic gap is the impermeability of the blood-brain barrier to many drugs. Thus, developing new strategies to bypass this barrier and deliver therapeutic agents to the central nervous system (CNS) is crucial. The intranasal (IN) route has emerged as a promising approach in animal models of neurodegenerative diseases. This method of administration is gaining attention as a viable alternative for delivering various pharmacological agents, including proteins, miRNA, and oligonucleotides, to the CNS. It offers advantages over oral and intravenous routes. However, translating IN formulations from preclinical models to clinical practice presents several challenges. Assessing the adequacy of current clinical trials in evaluating IN delivery efficacy is crucial. Furthermore, the introduction of novel formulations such as nanoparticles sparks excitement for enhancing the effectiveness of IN drug administration compared to traditional free drug solutions. This review summarizes recent advancements in delivering therapeutic molecules to the CNS to treat neurodegenerative diseases. We explore critical strategies to overcome the blood-brain barrier obstacle, focusing on recent progress using the IN route as a potential avenue for effective neurodegenerative disease therapies. Additionally, we will delve into the preclinical studies that have provided the basis for the clinical trials conducted.\n\nID: 40727589\nTitle: Ginseng-Derived Exosomes Attenuate Immune Evasion in NSCLC via PD-L1 Modulation.\nAbstract: Non-small cell lung cancer (NSCLC) is a major cause of cancer-related death worldwide. While PD-1/PD-L1 immune checkpoint blockade has shown promise, its efficacy is often limited by tumor-induced immune evasion. Ginseng-derived exosomes (G-Exos), as natural plant-based nanocarriers, may offer a novel strategy for immunomodulation. This study investigated the potential of G-Exos to regulate PD-L1 expression and enhance anti-tumor immunity in NSCLC. Exosomes were isolated from ginseng cell cultures and characterized via transmission electron microscopy and nanoparticle tracking analysis. Uptake by NSCLC cells was confirmed using PKH26 labeling. In vitro, NSCLC cells were co-cultured with activated T cells to evaluate cytotoxicity (colony formation), cytokine secretion [enzyme-linked immunosorbent assay (ELISA)], and T-cell activation (flow cytometry). PD-L1 expression was assessed by quantitative polymerase chain reaction (qPCR) and Western blot. In vivo, C57BL/6 mice (n = 20) bearing Lewis lung carcinoma (LLC) tumors were randomized into four groups (n = 5/group): PBS, G-Exos (10\u00a0\u03bcg), anti-PD-L1 (8\u00a0\u03bcg), or combination therapy. Treatments were administered intravenously every other day for 20 days. Tumor growth was measured, and tissues were analyzed by immunohistochemistry and flow cytometry. G-Exos were efficiently internalized by NSCLC cells and demonstrated immunostimulatory properties in vitro. They enhanced T-cell-mediated cytotoxicity, as reflected by reduced tumor colony formation, and promoted immune activation, evidenced by increased IL-2 and IFN-\u03b3 secretion and a higher proportion of CD8\u207a T cells expressing TNF-\u03b1 and perforin. Mechanistically, G-Exos downregulated PD-L1 expression at both transcriptional and translational levels in NSCLC cells. In vivo, G-Exos treatment significantly inhibited tumor growth and, when combined with anti-PD-L1 monoclonal antibody, exhibited a synergistic effect characterized by greater tumor suppression and increased infiltration of cytotoxic CD8\u207a T cells in the tumor microenvironment. Ginseng-derived exosomes downregulate PD-L1 and enhance T-cell function, counteracting immune evasion in NSCLC. Their synergy with anti-PD-L1 therapy supports their potential as adjuvant nanotherapeutics in cancer immunotherapy.\n\nID: 40713630\nTitle: The role of endolysosomal progranulin and TMEM106B in neurodegenerative diseases.\nAbstract: Although different neurodegenerative diseases are defined by distinct pathological proteins, they share many common features including protein aggregation. Despite this commonality, most current therapeutic approaches in the field, such as anti-aggregate antibodies, are focused on individual diseases or single neuropathologies with only limited success. The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases. Thus, these proteins are predicted to participate in common pathogenic pathways shared across various neurodegenerative diseases. Importantly, recent discoveries of TMEM106B amyloid fibrils in varied neurodegenerative diseases and glycosphingolipid regulation by progranulin and TMEM106B further support their central roles in cross-disease neurodegenerative mechanisms. This review summarizes recent advances in progranulin and TMEM106B function within the endolysosomal system and neurodegenerative diseases. It describes preclinical models and therapeutic approaches for progranulin- and TMEM106B-associated diseases. We also discuss future direction leading to novel alternative therapies targeting shared mechanisms in neurodegenerative diseases.\n\nID: 40672793\nTitle: Treatment of Postinflammatory Hyperpigmentation Following Acne With Microneedling and Panax Ginseng-Derived Exosomes.\nAbstract: This case report evaluated the efficacy of microneedling therapy system (MTS) combined with topical exosome therapy for the treatment of postinflammatory hyperpigmentation (PIH) following acne. Two patients were included in the study: a 32-year-old woman with scattered PIH on her forehead, cheeks, nose, and perioral area, and a 37-year-old man with hyperpigmentation on both cheeks. Both patients underwent 3 sessions of MTS spaced 3 weeks apart, followed by the immediate application of a topical exosome (P198 RECORE SB PLUS, P198 ExoNature, Primoris International Co., Ltd., Seoul, Republic of Korea). PIH severity was assessed using the PIH severity scale, with baseline scores of grade 2 (mild) for both patients. One month after the final session, posttreatment scores improved to grade 1 (trace) for both patients, as evaluated by 2 dermatologists. Both patients demonstrated significant improvements in hyperpigmentation and overall skin tone. The female patient achieved a more even complexion with visible lightening in affected areas, whereas the male patient experienced a marked reduction in cheek pigmentation. Both patients expressed high satisfaction with the results, and no adverse effects were reported. These findings suggest that the combination of MTS and topical exosomes is a promising, safe approach for managing PIH, particularly in individuals with darker skin types prone to pigmentation disorders.\n\nID: 40585387\nTitle: Multifunctional DNA hydrogels with light-triggered gas-therapy and controlled G-Exos release for infected wound healing.\nAbstract: Infectious wound healing remains a significant medical challenge due to chronic inflammation and bacterial colonization. Effective antimicrobial and anti-inflammatory therapies are essential to facilitate wound recovery. Herein, we introduce a highly biocompatible, ROS-responsive DNA hydrogel (LGAH), modified with aggregation-induced emission luminogens (AIEgen) and incorporating ginseng-derived exosomes (G-Exos) and nitric oxide (NO) donor-L-arginine (L-Arg) to promote healing of infected wounds. The hydrogel degrades in response to elevated ROS levels, releasing therapeutic agents. Upon laser irradiation, AIEgen generates 1O2, which activates L-Arg to produce NO, leading to a synergistic antimicrobial effect. NO is particularly effective at inhibiting bacterial growth and promoting angiogenesis, supporting wound healing. G-Exos modulate immune responses, reduce inflammation, and promote the transition from the inflammatory to the proliferative phase. They also enhance cell proliferation, migration, and collagen production, which are key to tissue regeneration. In vivo experiments demonstrated that LGAH significantly accelerates S. aureus-infected wound healing by modulating the wound microenvironment and promoting tissue regeneration. Transcriptomic analysis revealed that LGAH down-regulates gene expression in inflammation and immune response signaling pathways while up-regulating genes related to energy metabolism. Biosafety evaluations at cellular and animal levels have demonstrated that LGAH possesses excellent biocompatibility and biodegradability, making it ideal for tissue repair and regeneration. This multifunctional DNA hydrogel system offers a safe and promising strategy for the clinical treatment of infected wounds.\n\nID: 40520058\nTitle: Advancements in Nanotherapeutics for the Treatment of Depression via Intranasal Pathway: A Review.\nAbstract: Depression is a complex psychiatric disorder marked by persistent emotional disturbances such as sadness, hopelessness, and fatigue, frequently accompanied by psychosocial impairments. Current treatment approaches are hindered by limited efficacy, poor patient adherence, and the inability of many therapeutic agents to effectively penetrate the blood-brain barrier (BBB). The BBB, a selective and protective interface between the bloodstream and brain tissue, restricts drug delivery to the central nervous system (CNS), resulting in suboptimal concentrations of antidepressants at the target site and delayed therapeutic responses. This review explores the limitations of conventional drug delivery systems for depression and highlights the intranasal route as a promising non-invasive alternative for direct brain targeting. Intranasal delivery bypasses hepatic first-pass metabolism and systemic degradation, offering rapid drug absorption and CNS access through olfactory and trigeminal neural pathways. Among emerging strategies, nanotherapeutics have gained increasing attention due to their capacity to improve solubility, protect labile compounds, and provide sustained drug release. Nanoparticles can encapsulate both hydrophilic and lipophilic drugs, enhancing their pharmacokinetics and stability. When administered intranasally, these nanocarriers can directly reach the brain, potentially reducing dosage frequency and enhancing therapeutic outcomes, while minimizing systemic side effects. This review focuses on the latest advancements in intranasal nanotherapeutic formulations for depression, such as polymeric nanoparticles, nanoemulsions, solid lipid nanoparticles, and nanostructured lipid carriers. The synergistic integration of nanotechnology and targeted CNS delivery offers a transformative approach to overcome the challenges posed by the BBB and improve depression management. While preclinical findings are promising, further clinical studies are necessary to confirm safety, efficacy, and long-term outcomes. Overall, intranasal nanotherapeutics represent a compelling direction for the development of next-generation antidepressant therapies, aiming to achieve faster onset, improved adherence, and enhanced quality of life for patients suffering from depression.\n\nID: 40121965\nTitle: Edible ginseng-derived exosomes as drug delivery vehicles reduce the dose and improve the anti-cancer effect of CDDP.\nAbstract: Nanotechnology and nanomaterials have emerged as promising tools for the delivery of anti-tumor drug cisplatin (CDDP). However, concerns exist regarding potential toxicity and cost-effectiveness, limiting their clinical applications. In contrast, plant-derived exosomes (PDEs), as natural nanovesicles, offer significant advantages as drug delivery carriers due to their large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers. In this work, we established a ginseng-derived exosome (G-Exo)-based CDDP delivery system (G-CDDP) and evaluated its anti-tumor efficacy both in vitro and in vivo. The results demonstrated that G-CDDP effectively targeted tumor site, inhibiting the proliferation and migration and promoting apoptosis in U-87MG tumor cells. Notably, the amount of CDDP in G-CDDP required for achieving the same cytotoxic effect on tumor cells was 12.66 times lower than that of free CDDP. In U-87MG tumor-bearing mice, G-CDDP effectively targeted tumor sites and exhibited significant therapeutic effect. Collectively, these findings highlight the potent anti-tumor activity of G-CDDP at reduced CDDP dosage, positioning it as a promising and efficient alternative to conventional drug treatments in clinical settings.\n\nID: 39740230\nTitle: The Cardioprotective Effect of Ginseng Derived Exosomes via Inhibition of Oxidative Stress and Apoptosis.\nAbstract: Ginsenosides possess potential protective effects against cisplatin (CDDP)-induced toxicity, but the limited bioavailability of ginsenosides hampered their therapeutic application. Ginseng exosomes (G-Exo), which are active ingredients in ginseng, exhibit excellent biocompatibility and low immunogenicity. Here, G-Exo were isolated from ginseng roots through a combination of ultracentrifugation and sucrose gradient centrifugation techniques. Subsequently, the potential protective effect of G-Exo on CDDP induced cardiotoxicity, and its underlying mechanisms were explored. The findings demonstrated that G-Exo effectively mitigated CDDP-induced oxidative stress and apoptosis in vitro. Moreover, in vivo experiments revealed that G-Exo significantly inhibited the increases in serum cardiac troponin T (cTnT), creatine kinase (CK), and lactate dehydrogenase (LDH) levels in mice induced by CDDP. Histological assessment and tissue staining further corroborated that G-Exo alleviated the cardiac tissue damage and apoptosis caused by CDDP. Mechanistically, G-Exo were found to alleviate CDDP-induced apoptosis through blocking the MAPK signaling. Collectively, these results suggest that G-Exo hold the potential to mitigate cisplatin-induced cardiac injury by regulating the MAPK pathway, thereby highlighting the therapeutic potential of G-Exo as a protective agent against CDDP-induced cardiotoxicity.\n\nID: 39587576\nTitle: Chinese herbal medicine-derived extracellular vesicles as novel biotherapeutic tools: present and future.\nAbstract: Extracellular vesicles (EVs) are phospholipid bilayer-enclosed biological particles that are secreted by almost all living cells including animals, plants, and microorganisms. Chinese herbal medicines (CHM) have a long history of using plant-based remedies to treat and prevent human diseases. Chinese herbal medicine-derived extracellular vesicle (CHMEV) generic term refers to nanoscale membrane structures isolated from medicinal plants such as ginseng, ginger, and Panax notoginseng. In recent years, CHMEVs have garnered substantial attention as a novel class of functional components due to their high bioavailability, safety, easy accessibility, and diverse therapeutic effects, indicating their great potential for development as a new dosage form of CHM. Research on CHMEVs in traditional Chinese medicine (TCM) has become a prominent area of interest, opening new avenues for further exploration into the therapeutic effects and functional mechanisms of CHM. Nonetheless, as an emerging field, there is much unknown about these vesicles, and current research remains inconsistent. The review comprehensively summarizes the biogenesis, isolation methods, and physical, and biochemical characterizations of CHMEVs. Additionally, we highlight their biomedical applications as therapeutic agents and drug delivery carriers, including anti-inflammatory, anticancer, regenerative, and antiaging activities. Finally, we propose current challenges and future perspectives. By summarizing the existing literature, we aim to offer valuable clues and inspiration for future CHMEV research, thereby facilitating research standardization of CHMEVs in the treatment of human diseases and drug discovery.\n\nID: 39411956\nTitle: To Explore Nasal-Brain Lymphatic System for Brain-Targeted Drug Delivery and to Treat Neurodegenerative Diseases.\nAbstract: Brain-related Neurodegenerative Disorders (NDD) are the leading cause of low life expectancy globally. Brain-targeted drug delivery is required for treating most the NDD via bypassing the blood-brain barrier, and hepatic first-pass metabolism. The nasal-brain drug delivery route has the advantage of locally enhancing drug delivery to the brain, mainly through the olfactory route rather than systemic circulation. To overcome the limitations of nasal-brain drug delivery, a nanocarrier approach and mucoadhesive polymers are needed. Notwithstanding these constraints, various nanotechnology techniques have been created, including polymeric micelles, liposomes, polymeric nanoparticles, solid lipid nanoparticles, & nano-emulsions. This review aims to explore the intranasal pathway for drug delivery through the nasal-brain lymphatic systems, considering brain anatomy and physiology along with a drug formulation design approach.\n\nID: 38132480\nTitle: Improvement in Yield of Extracellular Vesicles Derived from Edelweiss Callus Treated with LED Light and Enhancement of Skin Anti-Aging Indicators.\nAbstract: The process of skin aging is currently recognized as a disease, and extracellular vesicles (EVs) are being used to care for it. While various EVs are present in the market, there is a growing need for research on improving skin conditions through microbial and plant-derived EVs. Edelweiss is a medicinal plant and is currently an endangered species. Callus culture is a method used to protect rare medicinal plants, and recently, research on EVs using callus culture has been underway. In this study, the researchers used LED light to increase the productivity of Edelweiss EVs and confirmed that productivity was enhanced by LED exposure. Additionally, improvements in skin anti-aging indicators were observed. Notably, M-LED significantly elevated callus fresh and dry weight, with a DW/FW ratio of 4.11%, indicating enhanced proliferation. Furthermore, M-LED boosted secondary metabolite production, including a 20% increase in total flavonoids and phenolics. The study explores the influence of M-LED on EV production, revealing a 2.6-fold increase in concentration compared to darkness. This effect is consistent across different plant species (Centella asiatica, Panax ginseng), demonstrating the universality of the phenomenon. M-LED-treated EVs exhibit a concentration-dependent inhibition of reactive oxygen species (ROS) production, surpassing dark-cultured EVs. Extracellular melanin content analysis reveals M-LED-cultured EVs' efficacy in reducing melanin production. Additionally, the expression of key skin proteins (FLG, AQP3, COL1) is significantly higher in fibroblasts treated with M-LED-cultured EVs. These results are expected to provide valuable insights into research on improving the productivity of plant-derived EVs and enhancing skin treatment using plant-derived EVs.\n\nID: 40395512\nTitle: TDP-43 Secretion via Extracellular Vesicles Is Regulated by Macroautophagy.\nAbstract: The pathological accumulation of the nuclear protein TDP-43 (TAR DNA-binding protein 43 kDa) in the cytoplasm is characteristic of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD-TDP), and its spread through the brain and spinal cord is closely associated with the progression of these two diseases. However, the mechanisms through which the TDP-43 pathology propagates throughout the central nervous system remain unclear. We recently reported the role of (macro)autophagy in the secretion of TDP-43 via extracellular vesicles (EVs). We found that among the autophagy modulators, bafilomycin A1 (Baf) and GRN (granulin precursor) deficiency impair the formation of autolysosomes and promote the secretion of TDP-43 by EVs. TDP-43 loading on EVs involves autophagy-related proteins and the knockdown of TDP-43 augmented Baf-induced EV release. Thus, our results suggest that the loss-of-function of TDP-43 accelerates release of EVs possibly derived from autophagosomes, which may mediate cell-to-cell spread of the TDP-43 pathology.\n\nID: 37720571\nTitle: Amelioration of colitis progression by ginseng-derived exosome-like nanoparticles through suppression of inflammatory cytokines.\nAbstract: Damage to the healthy intestinal epithelial layer and regulation of the intestinal immune system, closely interrelated, are considered pivotal parts of the curative treatment for inflammatory bowel disease (IBD). Plant-based diets and phytochemicals can support the immune microenvironment in the intestinal epithelial barrier for a balanced immune system by improving the intestinal microecological balance and may have therapeutic potential in colitis. However, there have been only a few reports on the therapeutic potential of plant-derived exosome-like nanoparticles (PENs) and the underlying mechanism in colitis. This study aimed to assess the therapeutic effect of PENs from Panax ginseng, ginseng-derived exosome-like nanoparticles (GENs), in a mouse model of IBD, with a focus on the intestinal immune microenvironment. To evaluate the anti-inflammatory effect of GENs on acute colitis, we treated GENs in Caco2 and lipopolysaccharide (LPS) -induced RAW 264.7 macrophages and analyzed the gene expression of pro-inflammatory cytokines and anti-inflammatory cytokines such as TNF-\u03b1, IL-6, and IL-10 by real-time PCR (RT-PCR). Furthermore, we further examined bacterial DNA from feces and determined the alteration of gut microbiota composition in DSS-induced colitis mice after administration of GENs through 16S rRNA gene sequencing analysis. GENs with low toxicity showed a long-lasting intestinal retention effect for 48 h, which could lead to effective suppression of pro-inflammatory cytokines such as TNF-\u03b1 and IL-6 production through inhibition of NF-\u03baB in DSS-induced colitis. As a result, it showed longer colon length and suppressed thickening of the colon wall in the mice treated with GENs. Due to the amelioration of the progression of DSS-induced colitis with GENs treatment, the prolonged survival rate was observed for 17 days compared to 9 days in the PBS-treated group. In the gut microbiota analysis, the ratio of Firmicutes/Bacteroidota was decreased, which means GENs have therapeutic effectiveness against IBD. Ingesting GENs would be expected to slow colitis progression, strengthen the gut microbiota, and maintain gut homeostasis by preventing bacterial dysbiosis. GENs have a therapeutic effect on colitis through modulation of the intestinal microbiota and immune microenvironment. GENs not only ameliorate the inflammation in the damaged intestine by downregulating pro-inflammatory cytokines but also help balance the microbiota on the intestinal barrier and thereby improve the digestive system.\n\nID: 37563705\nTitle: TMEM106B aggregation in neurodegenerative diseases: linking genetics to function.\nAbstract: Mutations of the gene TMEM106B are risk factors for diverse neurodegenerative diseases. Previous understanding of the underlying mechanism focused on the impairment of lysosome biogenesis caused by TMEM106B loss-of-function. However, mutations in TMEM106B increase its expression level, thus the molecular process linking these mutations to the apparent disruption in TMEM106B function remains mysterious. Recent new studies reported that TMEM106B proteins form intracellular amyloid filaments which universally exist in various neurodegenerative diseases, sometimes being the dominant form of protein aggregation. In light of these new findings, in this review we systematically examined previous efforts in understanding the function of TMEM106B in physiological and pathological conditions. We propose that TMEM106B aggregations could recruit normal TMEM106B proteins and interfere with their function. TMEM106B mutations could lead to lysosome dysfunction by promoting the aggregation of TMEM106B and reducing these aggregations may restore lysosomal function, providing a potential therapeutic target for various neurodegenerative diseases.\n\nID: 37542285\nTitle: Anti-glioma effect of ginseng-derived exosomes-like nanoparticles by active blood-brain-barrier penetration and tumor microenvironment modulation.\nAbstract: Inhibition of tumor growth and normalization of immune responses in the tumor microenvironment (TME) are critical issues for improving cancer therapy. However, in the treatment of glioma, effective nanomedicine has limited access to the brain because of the blood-brain barrier (BBB). Previously, we demonstrated nano-sized ginseng-derived exosome-like nanoparticles (GENs) consisting of phospholipids including various bioactive components, and evaluated anti-tumor immune responses in T cells and Tregs to inhibit tumor progression. It was found that the enhanced targeting ability of GENs to the BBB and glioma induced a significant therapeutic effect and exhibited strong efficacy in recruiting M1 macrophage expression in the TME. GENs were demonstrated to be successful candidates in glioma therapeutics both in vitro and in vivo, suggesting excellent potential for inhibiting glioma progression and regulating tumor-associated macrophages (TAMs).\n\nID: 37519873\nTitle: Transcranial application of magnetic pulses for improving brain drug delivery efficiency via intranasal injection of magnetic nanoparticles.\nAbstract: As the blood-brain barrier (BBB) hinders efficient drug delivery to the brain, drug delivery via the intranasal pathway, bypassing the BBB, has received considerable attention. However, intranasal administration still has anatomical and physiological limitations, necessitating further solutions to enhance effectiveness. In this study, we used transcranial magnetic stimulation (TMS) on fluorescent magnetic nanoparticles (MNPs) of different sizes (50, 100, and 300 nm) to facilitate MNP's transportation and delivery to the brain parenchyma. To validate this concept, anesthetized rats were intranasally injected with the MNPs, and TMS was applied to the center of the head. As the result, a two-fold increase in brain MNP delivery was achieved using TMS compared with passive intranasal administration. In addition, histological analysis that was performed to investigate the safety revealed no gross or microscopic damages to major organs caused by the nanoparticles. While future studies should establish the delivery conditions in humans, we expect an easy clinical translation in terms of device safety, similar to the use of conventional TMS. The strategy reported herein is the first critical step towards effective drug transportation to the brain.\n\nID: 35159272\nTitle: Cerebrospinal Fluid EV Concentration and Size Are Altered in Alzheimer's Disease and Dementia with Lewy Bodies.\nAbstract: Alzheimer's disease (AD), dementia with Lewy bodies (DLB) and frontotemporal dementia (FTD) represent the three major neurodegenerative dementias characterized by abnormal brain protein accumulation. In this study, we investigated extracellular vesicles (EVs) and neurotrophic factors in the cerebrospinal fluid (CSF) of 120 subjects: 36 with AD, 30 with DLB, 34 with FTD and 20 controls. Specifically, CSF EVs were analyzed by Nanoparticle Tracking Analysis and neurotrophic factors were measured with ELISA. We found higher EV concentration and lower EV size in AD and DLB groups compared to the controls. Classification tree analysis demonstrated EV size as the best parameter able to discriminate the patients from the controls (96.7% vs. 3.3%, respectively). The diagnostic performance of the EV concentration/size ratio resulted in a fair discrimination level with an area under the curve of 0.74. Moreover, the EV concentration/size ratio was associated with the p-Tau181/A\u03b242 ratio in AD patients. In addition, we described altered levels of cystatin C and progranulin in the DLB and AD groups. We did not find any correlation between neurotrophic factors and EV parameters. In conclusion, the results of this study suggest a common involvement of the endosomal pathway in neurodegenerative dementias, giving important insight into the molecular mechanisms underlying these pathologies.\n\nID: 34586821\nTitle: Plant Exosomes As Novel Nanoplatforms for MicroRNA Transfer Stimulate Neural Differentiation of Stem Cells In Vitro and In Vivo.\nAbstract: Differentiation of bone marrow derived mesenchymal stem cells (BMSCs) into functional neural cells has been widely investigated for treating neural diseases. However, the limited neural differentiation of BMSCs remains a big challenge to overcome. Herein, for the first time, ginseng-derived exosomes (G-Exos) were demonstrated to have excellent efficiency in stimulating the neural differentiation of BMSCs by transferring the incorporated miRNAs to BMSCs efficiently. In vivo, a photo-cross-linkable hydrogel with chemokine and G-Exos loaded shows strong efficacy in recruiting and directing the neural differentiation of BMSCs in the program. G-Exos were demonstrated to be promising nanoplatforms in transferring plant-derived miRNAs to mammalian stem cells for neural differentiation both in vitro and in vivo, possessing great potential in neural regenerative medicine.\n\nID: 33796852\nTitle: Fronto-temporal dementia risk gene TMEM106B has opposing effects in different lysosomal storage disorders.\nAbstract: TMEM106B is a transmembrane protein localized to the endo-lysosomal compartment. Genome-wide association studies have identified TMEM106B as a risk modifier of Alzheimer's disease and frontotemporal lobar degeneration, especially with progranulin haploinsufficiency. We recently demonstrated that TMEM106B loss rescues progranulin null mouse phenotypes including lysosomal enzyme dysregulation, neurodegeneration and behavioural alterations. However, the reason whether TMEM106B is involved in other neurodegenerative lysosomal diseases is unknown. Here, we evaluate the potential role of TMEM106B in modifying the progression of lysosomal storage disorders using progranulin-independent models of Gaucher disease and neuronal ceroid lipofuscinosis. To study Gaucher disease, we employ a pharmacological approach using the inhibitor conduritol B epoxide in wild-type and hypomorphic Tmem106b-/- mice. TMEM106B depletion ameliorates neuronal degeneration and some behavioural abnormalities in the pharmacological model of Gaucher disease, similar to its effect on certain progranulin null phenotypes. In order to examine the role of TMEM106B in neuronal ceroid lipofuscinosis, we crossbred Tmem106b-/- mice with Ppt1-/-, a genetic model of the disease. In contrast to its conduritol B epoxide-rescuing effect, TMEM106B loss exacerbates Purkinje cell degeneration and motor deficits in Ppt1-/- mice. Mechanistically, TMEM106B is known to interact with subunits of the vacuolar ATPase and influence lysosomal acidification. In the pharmacological Gaucher disease model, the acidified lysosomal compartment is enhanced and TMEM106B loss rescues in vivo phenotypes. In contrast, gene-edited neuronal loss of Ppt1 causes a reduction in vacuolar ATPase levels and impairment of the acidified lysosomal compartment, and TMEM106B deletion exacerbates the mouse Ppt1-/- phenotype. Our findings indicate that TMEM106B differentially modulates the progression of the lysosomal storage disorders Gaucher disease and neuronal ceroid lipofuscinosis. The effect of TMEM106B in neurodegeneration varies depending on vacuolar ATPase state and modulation of lysosomal pH. These data suggest TMEM106B as a target for correcting lysosomal pH alterations, and in particular for therapeutic intervention in Gaucher disease and neuronal ceroid lipofuscinosis.\n\nID: 42595562\nTitle: Lysosome-targeted protein degradation platforms for spatiotemporally controlled degradation.\nAbstract: Lysosome-targeted protein degradation (LTPD) represents a therapeutic strategy that degrades membrane and extracellular target proteins through the endolysosomal pathway. LTPD chimeras are molecular degraders that mediate LTPD, but their in vivo performance is limited by poor spatiotemporal control of degradation-existing chimeras have suboptimal pharmacokinetics, tissue selectivity, and endolysosomal trafficking. To overcome these hurdles associated with chimeras, LTPD platforms have emerged. LTPD platforms function as chimera-loaded systems for targeted delivery and controlled release of chimeras, or as platform-based degraders that mediate disease-targeted and on-demand degradation without chimeras. We discuss how LTPD platforms spatiotemporally control degradation and describe their therapeutic applications. In particular, we summarize the design principles of LTPD platforms to address the stringent requirements imposed by the LTPD process. These principles may contribute to the rational design of LTPD platforms.\n\nID: 42595252\nTitle: URG7-Driven Homeostatic Adaptation Protects SH-SY5Y Cells from 6-OHDA Neurotoxicity.\nAbstract: Parkinson's disease (PD) is characterized by progressive dopaminergic neurodegeneration associated with oxidative stress, mitochondrial dysfunction, endoplasmic reticulum (ER) stress, and impaired proteostasis. In this study, we investigated the role of Up-Regulated Gene 7 (URG7), an ER-resident protein, in regulating cellular stress responses in SH-SY5Y neuroblastoma cells exposed to 6-hydroxydopamine (6-OHDA), a widely used in vitro model of PD. URG7 overexpression significantly enhanced activation of the adaptive unfolded protein response (UPR), particularly the PERK/eIF2\u03b1/ATF4 pathway, while limiting ER stress-induced damage. Moreover, URG7 promoted protein quality control mechanisms by stimulating both the ubiquitin-proteasome system and autophagy, as demonstrated by increased ubiquitination, proteasome activity, and upregulation of Beclin-1 and LC3-II. URG7 also prevented intracellular calcium overload and reduced the expression of proteins involved in the SOCE pathway, thereby preserving calcium homeostasis under oxidative stress conditions. In addition, URG7 attenuated G1 cell cycle arrest and reduced the expression of pro-apoptotic markers, including p53, p21, Bax, and cleaved PARP, while promoting pro-survival signaling pathways such as AKT and ERK1/2. Collectively, these findings identify URG7 as an important regulator of adaptive stress responses and suggest its possible involvement in neuroprotective mechanisms associated with neurodegenerative disorders characterized by oxidative stress.\n\nID: 42588134\nTitle: Natural Bioactive Compounds Targeting Key Hallmarks of Aging: Functional Food Potential of Spermidine, Fisetin, Berberine, and Urolithin A.\nAbstract: Naturally derived bioactive compounds that modulate aging-associated mechanisms have attracted growing research interest, yet few reviews examine how such compounds might act together. This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations.\n\nID: 42587819\nTitle: Autophagy at the Crossroads of Protein and RNA Toxicity in Repeat Expansion Cerebellar Ataxias.\nAbstract: Repeat expansion cerebellar ataxias comprise a genetically and mechanistically heterogeneous group of neurodegenerative disorders unified by the pathological expansion of short tandem repeats (STRs) beyond a disease-causing threshold. Depending on their genomic localization, these expansions can lead to toxic protein gain-of-function, as in polyglutamine (polyQ) cerebellar ataxias, or to RNA-mediated toxicity and repeat-associated non-AUG (RAN) translation, for which recent evidence supports a major pathogenic role in non-coding spinocerebellar ataxias (SCAs). Despite these distinct upstream mechanisms, disruption of neuronal homeostasis occurs through converging pathogenic processes, including proteostasis impairment, transcriptional dysregulation, and mitochondrial dysfunction, leading to progressive neuronal loss. Importantly, impaired autophagy has been consistently reported across multiple repeat expansion ataxias, including both dominant SCAs and recessive conditions, such as Friedreich's ataxia, suggesting that impairment of this pathway may represent a shared downstream event in disease progression. Indeed, in polyQ cerebella ataxias, the accumulation of misfolded and aggregation-prone proteins places a substantial burden on cellular quality control systems, particularly the ubiquitin-proteasome system and autophagy. Similarly, in non-coding SCAs, toxic RNA species and RAN-derived peptides might interfere with protein clearance mechanisms and contribute to cellular stress. In this review, we will discuss the evidence supporting autophagy impairment as a convergent pathogenic pathway in repeat expansion cerebellar ataxias.\n\nID: 42586468\nTitle: Cobalt oxide nanoparticles induce neurodevelopmental toxicity through ferritinophagy-mediated ferroptosis: Evidence from zebrafish and cell models.\nAbstract: Cobalt oxide nanoparticles (Co3O4 NPs) are widely used in lithium batteries and semiconductors, and are often detected in water, soil, and occupational environments. While cobalt ions are linked to neurodegenerative diseases, the neurodevelopmental toxicity of Co3O4 NPs remains poorly understood. Ferroptosis, a process regulated by iron homeostasis, can be triggered by ferrous overload through ferritinophagy. This study explores how Co3O4 NPs induce ferritinophagy and their role in neurodevelopmental toxicity. Zebrafish larvae exposed to Co3O4 NPs at concentrations of 0, 5, and 50\u202fmg/L for up to 120\u202fh post-fertilization (hpf) exhibited dose-dependent developmental toxicity, including delayed hatching, increased malformations, and impaired motor behavior. Transgenic zebrafish models demonstrated neuronal shortening, reduced fluorescence, and altered neurotransmitter profiles, as supported by liquid chromatography-tandem mass spectrometry. Co3O4 NPs induced oxidative stress, leading to iron overload, lipid peroxidation (elevated MDA, depleted glutathione), and ferritinophagy activation, as evidenced by changes in genes and proteins related to iron metabolism (trf, fpn, slc7a11) and ferroptosis (GPX4, ACSL4, FTH1, NCOA4). Ferritinophagy was further confirmed using autophagy inhibitors, demonstrating its role in neurotoxicity. Additionally, Vitamin E (d-\u03b1-tocopherol), a lipid-soluble antioxidant that suppresses lipid peroxidation, reduced neurodevelopmental abnormalities, supporting that Co3O4 NP-induced toxicity occurs through ferritinophagy-mediated ferroptosis, leading to neurotransmitter dysregulation. These findings were corroborated in human neuroblastoma cells (SH-SY5Y/SK-N-SH). In conclusion, Co3O4 NPs disrupt iron homeostasis, activate ferritinophagy, and induce ferroptosis, resulting in neurotransmitter dysregulation and neurodevelopmental toxicity. These results provide new insights for assessing the neurodevelopmental toxicity and environmental risk of Co3O4 NPs and similar nanomaterials.\n\nID: 42586275\nTitle: SGLT2 inhibitor alleviates hydrocephalus post intracerebral hemorrhage through enhancing autophagy via activating MEK/ERK pathway.\nAbstract: To investigate the neurovascular protective effects and underlying mechanisms of the SGLT2 inhibitor dapagliflozin on post-hemorrhagic hydrocephalus (PHH) following intracerebral hemorrhage (ICH). An ICH-induced PHH rat model was established. Rats were treated with varying doses of dapagliflozin to evaluate dose-response neuroprotection. To elucidate the underlying molecular pathways, selective autophagy and MEK inhibitors were subsequently administered. Dapagliflozin dose-dependently attenuated ventricular enlargement, improved neurological deficits, and reduced neuroinflammation post-ICH. Crucially, autophagy inhibition reversed these benefits, concurrently impairing glymphatic clearance, reducing cerebral blood flow (CBF), and disrupting neurovascular unit (NVU) integrity. Furthermore, MEK inhibition counteracted the dapagliflozin-induced enhancement of autophagy, confirming the MEK/ERK pathway's regulatory role. Dapagliflozin mitigates PHH by activating the MEK/ERK pathway to enhance autophagy. This mechanistic axis is essential for maintaining NVU integrity, improving glymphatic permeability, and increasing CBF perfusion, presenting SGLT2 inhibition as a promising translational therapy for ICH complications.\n\nID: 42580438\nTitle: Current Clinical Evidence on Nose-to-Brain Drug Delivery.\nAbstract: Intranasal delivery is increasingly recognised as a promising strategy for direct drug transport to the brain via the nose-to-brain pathway, bypassing the blood-brain barrier and improving therapeutic efficacy. This approach has shown potential in the treatment of neurological disorders, including Alzheimer's disease, Parkinson's disease, epilepsy, multiple sclerosis, and acute psychiatric conditions, as well as in emergencies such as anxiety attacks and migraine episodes. Recent clinical studies investigating intranasal formulations of rivastigmine, insulin, and olanzapine, among other drugs, have provided encouraging evidence supporting the clinical translation of this delivery strategy. In addition, FDA-approved intranasal products indicated for central nervous system disorders, including diazepam and midazolam for seizure management, and triptans for migraine, demonstrate the growing clinical relevance of intranasal drug delivery. Both preclinical and clinical studies have reported encouraging outcomes, particularly when intranasal delivery is combined with nanoformulations and specialised delivery devices designed to enhance olfactory deposition. Intranasal administration is non-invasive, painless, and may improve patient adherence while enhancing brain bioavailability. Nevertheless, further well-designed clinical studies are required to establish the long-term safety, efficacy, and clinical applicability of this delivery strategy.\n\nID: 42578428\nTitle: LPR-1-Mediated targeted intranasal delivery of lentinan-loaded polymeric nanocarriers for GBM therapy via modulation of apoptotic signalling.\nAbstract: To develop and evaluate a lactoferrin (Lf)-functionalized polyethylene glycol (PEG)-grafted chitosan (CS) nanocarriers (NCs) for low-density lipoprotein receptor-related protein-1 (LRP1)-mediated intranasal delivery of lentinan (LNT) to enhance brain targeting and anti-glioblastoma (GBM) efficacy. Lf-LNT-PEG-CS-NCs were prepared, optimized, and characterized for particle size, entrapment efficiency, coating efficiency, and release behavior. Ex vivo permeation, cellular uptake, cytotoxicity, apoptosis, pharmacokinetic, and biodistribution studies were performed using U87 MG cells and Wistar rats. The optimized NCs exhibited a particle size of 205.3\u2009\u00b1\u200911\u2009nm, entrapment efficiency of 71.52\u2009\u00b1\u20090.98%, and coating efficiency of 92.42\u2009\u00b1\u20090.94%, with sustained drug release for 36\u2009h. The permeation increased by 2.86-fold, while cellular uptake reached 78.38\u2009\u00b1\u20093.76%. Treatment significantly reduced U87 MG cell viability (84.21\u2009\u00b1\u20092.75% inhibition) and induced apoptosis with 64.55\u2009\u00b1\u20092.28% G0/G1 arrest, accompanied by reduced COX-2 (55.81\u2009\u00b1\u20092.91%) and Bcl-2 (59.65\u2009\u00b1\u20091.95%) expression and increased caspase-3 (73.10\u2009\u00b1\u20092.91%). Intranasal administration achieved a CSF Cmax of 46.72\u2009\u00b1\u20093.78\u2009\u03bcg/mL and brain accumulation of 42.83\u2009\u00b1\u20092.59\u2009\u03bcg/mL. LRP-1-targeted Lf-LNT-PEG-CS-NCs significantly enhanced intranasal brain delivery, cellular uptake, and apoptotic activity of LNT, demonstrating a promising noninvasive platform for targeted GBM therapy.\n\nID: 42577161\nTitle: \u03b1-Synuclein burden amplification in Parkinson's disease: a unified genetic, molecular, and cellular framework.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized pathologically by the accumulation and propagation of \u03b1-synuclein (\u03b1-syn). Although \u03b1-syn aggregation is considered central to PD pathogenesis, increasing evidence suggests that \u03b1-syn abundance may be as important as its conformational state. Genetic studies have demonstrated an SNCA dosage effect, with gene duplication and triplication associated with progressively more severe familial PD phenotypes. Complementary evidence indicates that dysfunction of protein clearance pathways, particularly the autophagy-lysosome system, promotes intracellular \u03b1-syn accumulation and increases its neurotoxic potential. In this review, we propose \u03b1-syn multiplication as an integrative framework for interpreting PD pathogenesis. This concept extends beyond SNCA copy-number variation to encompass processes that increase the effective \u03b1-syn burden within neurons or across neural networks, including increased gene expression, impaired degradation, disrupted proteostasis, and pathological propagation. We summarize \u03b1-syn structural dynamics and the concentration-dependent distribution of monomeric, oligomeric, and fibrillar species. We then review evidence from SNCA gene-dosage studies and examine the role of the autophagy-lysosome pathway in regulating \u03b1-syn homeostasis, with particular emphasis on recent experimental findings demonstrating that autophagy deficiency exacerbates \u03b1-syn accumulation and neurodegeneration in human \u03b1-syn bacterial artificial chromosome transgenic mice. Collectively, the available genetic, biochemical, and experimental evidence supports a model in which the balance between \u03b1-syn production and clearance influences disease progression alongside protein misfolding. The interaction between increased protein burden and impaired clearance capacity provides a unifying mechanism linking familial and sporadic forms of PD. We propose that \u03b1-syn multiplication offers an integrative framework for understanding PD pathogenesis, provides a quantitative perspective on disease heterogeneity, and highlights therapeutic opportunities aimed at reducing \u03b1-syn burden and restoring proteostatic balance.\n\nID: 42576648\nTitle: p62/SQSTM1: From an autophagy receptor to a condensate organizer of selective autophagy and stress signaling.\nAbstract: Upon exposure to stress, cells activate a variety of stress-response and quality-control mechanisms to maintain homeostasis. Dysregulation of these processes is implicated in numerous diseases, including cancer, liver disorders, and neurodegenerative diseases. p62/Sequestosome 1 (SQSTM1) is a multifunctional protein that plays a central role in protein homeostasis and stress responses by regulating autophagy and signal transduction pathways. Through its multiple protein-interacting domains, p62 functions both as a scaffold for selective autophagic degradation and as a signaling hub. Since our previous review of p62 a decade ago, substantial progress has been made in elucidating its molecular functions and physiological roles. Notably, p62 undergoes liquid-liquid phase separation with ubiquitinated proteins to form membraneless condensates, termed p62 bodies, when cells are exposed to proteotoxic stress. By sequestering specific proteins, p62 bodies act as platforms for autophagy-dependent degradation and stress signaling. These findings have substantially revised our view of p62 function, which was previously considered primarily as a receptor simply linking ubiquitinated substrates to autophagic membranes and connecting signaling molecules. This conceptual shift from one-to-one molecular interactions to multivalent, multimolecular, higher-order assemblies has fundamentally redefined the functional landscape of p62. In this review, we highlight how p62 bodies integrate selective autophagy and stress signaling, with a particular emphasis on their emerging roles in disease pathogenesis and their potential as therapeutic targets.\n\nID: 42576524\nTitle: The Double-Edged Sword: A Structured Narrative Review of Microglial Phenotypic Transition as a Pivotal Driver and Therapeutic Target in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder primarily involving the loss of dopaminergic neurons and pathological \u03b1-synuclein (\u03b1-syn) aggregation. A pivotal feature of PD pathogenesis is the dual role of microglia, which shifts from maintaining neuronal homeostasis to driving neuroinflammation and neurodegeneration. The mechanisms underlying this functional transition and its consequences for disease progression require a comprehensive synthesis. A structured PubMed search was performed using the keywords \"Parkinson's disease\", \"microglia\", \"neuroinflammation\", \"\u03b1-synuclein\", \"polarization\", \"tunneling nanotubes (TNTs)\", \"NF-\u03baB\", and \"NLRP3\". Relevant combinations of these terms were also used. A total of 2952 records were retrieved up to December 2025. Of these, 147 studies were included based on relevance to microglial polarization, neuroinflammation, \u03b1-syn-related pathology, and intercellular communication mechanisms. In early PD stages, microglia exert neuroprotective effects by transferring excess neuronal \u03b1-syn via TNTs, delivering healthy mitochondria, and clearing \u03b1-syn through autophagy. With disease progression, accumulated \u03b1-syn promotes microglial polarization toward the M1 phenotype. This shift activates TLR2/4, TREM2, MHCII, and RAGE receptors, triggering NF-\u03baB/NLRP3 pathways, releasing pro-inflammatory cytokines, and generating NOX2-derived ROS. The resulting neuroinflammatory cascade not only damages dopaminergic neurons directly but also disrupts astrocyte function and blood-brain barrier integrity, creating a self-perpetuating cycle of inflammation and neurodegeneration. These findings support dysregulated microglial polarization as an important component of PD pathobiology, but the available evidence remains weighted toward preclinical models. Future work should better define the timing, heterogeneity, and clinical measurability of microglial state transitions before microglia-targeted strategies can be translated with confidence. Microglial polarization may represent a potential therapeutic direction in Parkinson's disease, although further mechanistic and clinical validation and more precise biomarker definition remain necessary.\n\nID: 42570971\nTitle: Brain-targeted intranasal aripiprazole via modified chitosan nanoparticles: controlled release, pharmacokinetics, and pharmacodynamics.\nAbstract: Schizophrenia remains one of the most disabling mental disorders, and effective therapy is still limited by the difficulty of delivering drugs across the blood-brain barrier. Aripiprazole (Ari), a first-line atypical antipsychotic, exhibits restricted clinical performance due to poor solubility, extensive hepatic metabolism, and limited brain exposure. Herein, a novel intranasal nanocarrier system was developed to enable direct and sustained delivery of Ari to the brain. Chitosan nanoparticles (Cs-NPs) surface-modified with sodium dodecyl sulfate (SDS) were prepared by the ionic gelation method and optimized using a Box-Behnken design to evaluate the effects of SDS concentration, pH, and chitosan-to-tripolyphosphate ratio on particle size, zeta potential, and drug entrapment. The optimized formulation showed a mean particle size of ~\u2009200\u00a0nm, a positive surface charge, and an entrapment efficiency of 76.98\u2009\u00b1\u20097.6%. Transmission electron microscopy confirmed spherical morphology, while the in vitro release profile exhibited an initial burst followed by a sustained phase, indicating controlled-release behavior. Pharmacokinetic evaluation using LC-MS/MS revealed significantly enhanced Ari bioavailability and brain uptake following intranasal administration of the optimized Cs-NPs compared with oral, intravenous, and intranasal solutions. Pharmacodynamic testing in a ketamine-induced psychosis rat model (open-field and forced-swim tests) demonstrated improved antipsychotic efficacy. Neurochemical analysis showed restoration of dopamine and \u03b3-aminobutyric acid levels, while histopathological findings confirmed structural improvement in hippocampal and cortical regions. Collectively, these results highlight the potential of modified Cs-NPs as a controlled-release, nose-to-brain delivery platform that enhances the therapeutic performance of Ari for the management of schizophrenia.\n\nID: 42552039\nTitle: Molecular insights of peroxisome proliferator-activated receptor-\u03b3 signalling in amyotrophic lateral sclerosis and Huntington's disease.\nAbstract: Progressive neuronal loss is a hallmark of neurodegenerative diseases like Huntingtons disease (HD) and Amyotrophic lateral sclerosis (ALS) which are caused by convergent mechanisms such as oxidative stress, mitochondrial dysfunction, neuroinflammation, impaired autophagy and dysregulated cell death pathways. Both conditions share significant disruptions in metabolic and inflammatory signalling despite having different genetic origins and clinical manifestations; underscoring the necessity of pathway-oriented treatment approaches. In the central nervous system, peroxisome proliferator-activated receptor-\u03b3 (PPAR-\u03b3), a ligand-activated nuclear receptor has become an important regulator of inflammation, redox homeostasis, mitochondrial biogenesis and cellular stress responses. After giving a thorough overview of PPAR-\u03b3 structure activation and transcriptional regulation and the PGC-1\u03b1-mediated mitochondrial biogenesis axis, this chapter delves deeply into its interactions with major signalling pathways such as NF-\u03baB, Wnt/\u03b2-catenin Nrf2/ARE and the autophagy-apoptosis networks. With a focus on experimental data showing PPAR-\u03b3 signaling's neuroprotective, anti-inflammatory, antioxidant and metabolic regulatory roles the pathophysiology of ALS and HD is critically investigated. Lastly the need for improved biomarkers, tailored multi-target strategies and selective modulators is highlighted in the discussion of current therapeutic limitations and translational difficulties.\n\nID: 42565117\nTitle: Beyond the genetic code: orchestrating epigenetic and immune landscapes with multivalent mRNA-exosome vaccines.\nAbstract: mRNA therapeutics are transitioning from transient anti-viral vaccines into precise cancer immunotherapies capable of orchestrating potent antigen-specific T-cell and humoral responses. However, therapeutic resistance within immunologically \"cold\" tumors remains a formidable barrier, necessitating multiaxial optimization across transcript architecture, neoantigen selection, delivery vector engineering, and tumor microenvironment (TME) reprogramming. This review synthesizes critical breakthroughs in mRNA biochemistry-including chemical nucleotide modifications, optimized untranslated regions, structural codon adjustments, and stringent purification methodologies-that extend transcript longevity while limiting off-target reactogenicity to maximize functional antigen expression. We evaluate multiomic neoantigen discovery workflows leveraging genomics, transcriptomics, immunoproteomics, and computational HLA-binding algorithms to refine patient-specific target selection. Next, we dissect advanced lipid nanoparticles, surface-functionalized biomaterials, and engineered extracellular vesicles optimized to enhance antigen-presenting cell tropism and lymphoid homing. We further detail how vaccine-induced cytokine fluxes actively remodel the TME, successfully reversing local immune tolerance and driving robust effector leukocyte infiltration into the tumor stroma. Specifically, we highlight the convergence of mRNA-mediated cytokine signaling and epigenetic imprinting, which cooperatively induce trained immunity for durable preventive surveillance. Finally, we delineate rational combinations with immune checkpoint blockades while addressing translational challenges: identifying predictive biomarkers, mapping presentation kinetics, and structuring adaptive clinical trial frameworks.\n\nID: 42564130\nTitle: Effects of transmembrane protein 106B genetic variations on disease progression in Parkinson's disease.\nAbstract: Transmembrane protein 106B (TMEM106B) variations not only act as genetic modifiers of the risk of developing frontotemporal lobar degeneration but also correlate with the heterogeneity of clinicopathological phenotypes in other neurodegenerative diseases. However, the roles of TMEM106B in Parkinson's disease (PD) are sparsely explored. This study aims to explore whether TMEM106B variants influence the trajectories of clinical phenotypes in PD. We longitudinally followed 241 PD patients and genotyped their single nucleotide polymorphism (SNP) of rs3173615. Patients were categorized according to rs3173615 genotypes into GG (major allele homozygotes), GC (heterozygotes), and CC (minor allele homozygotes) groups. All patients completed clinical evaluations and neuropsychological tests at baseline and every follow-up. Linear mixed-effects models were adopted to evaluate the association between rs3173615 genotypes and longitudinal disease progression in PD. At baseline, both the GG and GC groups presented less severe excessive daytime sleepiness than the CC group, and no association between the remaining clinical characteristics and the genotypes of rs3173615 was observed among the three groups. Longitudinally, compared with the CC group, the GC group manifested a significantly faster exacerbation of depression, visuospatial function and quality of life (QoL), and the GG group showed the same tendency as the GC group, though without statistical significance. TMEM106B rs3173615 is a genetic modifier for the trajectory of depression, visuospatial function and QoL in PD. Our findings suggest the potential involvement of TMEM106B in the pathogenesis of disease progression in PD, especially in the deterioration of depression, cognition and QoL.\n\nID: 42561602\nTitle: Insulin resistance as a driver of neuroinflammation and oxidative stress in Alzheimer's disease: Mechanistic links and therapeutic approaches.\nAbstract: Alzheimer's disease (AD) is a complex, multifactorial neurodegenerative disorder characterized by the accumulation of amyloid-\u03b2 plaques and hyperphosphorylated tau protein aggregates, leading to progressive cognitive decline. Growing evidence suggests that AD may also be considered a metabolic disorder closely associated with insulin resistance (IR). Impaired insulin signaling disrupts the PI3K/Akt and GSK3-\u03b2 pathways, resulting in synaptic dysfunction, neuronal loss, and aberrant protein phosphorylation. Moreover, IR contributes to mitochondrial dysfunction, oxidative stress, and chronic neuroinflammation within the central nervous system (CNS). These metabolic alterations, together with impaired energy homeostasis, dysregulate intracellular signaling cascades and exacerbate amyloid and tau pathology. This narrative review examines the mechanistic interplay among insulin resistance, oxidative stress, and neuroinflammation in AD, with particular emphasis on the shared cellular pathways that underlie disease progression. In addition, it summarizes emerging therapeutic strategies targeting insulin signaling, including pharmacological insulin-sensitizing agents, incretin-based therapies, lifestyle interventions, and bioactive natural compounds. The review also highlights advances in intranasal delivery strategies, which have emerged as a promising approach for enhancing brain targeting and improving therapeutic efficacy. Despite substantial progress, the precise mechanisms linking insulin resistance to neurodegeneration remain incompletely understood. Further mechanistic and translational studies are urgently required to elucidate these interactions and advance the development of effective therapeutic interventions.\n\nID: 42560023\nTitle: Evaluation of Antisense Oligonucleotide-Associated Neuronal Lysosomal Changes.\nAbstract: Antisense oligonucleotides (ASOs) are a rapidly growing therapeutic modality that directly modulate splicing or expression of disease-causing genes. ASOs are internalized through various endocytic mechanisms that converge on the endolysosomal pathway. Our work here aims to evaluate changes to the endolysosomal system following repeated ASO exposure. Histological examinations of nonhuman primates following repeated intrathecal administration of ASOs reveal dose-related neuronal microvesicular vacuolation in the hippocampus, cortex, and spinal cord. These changes are not associated with any neuronal degenerative changes or glial activation. Examination by electron microscopy reveals lysosomes containing stacked membranous material. We established an induced pluripotent stem cell-derived motor neuron (iPSC-MN) model that recapitulates these lysosome changes. ASO exposure did not cause any changes in iPSC-MN viability. To characterize lysosomal changes, we isolated lysosomes from iPSC-MNs after ASO treatment and quantified their protein and lipid contents by liquid chromatography-mass spectrometry. Our lipidomics studies documented increases in bis(monoacylglycerol)phosphate and lactosylceramide following ASO administration; proteomic analysis showed changes in several proteins, including decreases in four lysosomal hydrolases (Carboxypeptidase Q, \u00df-galactosidase, Cathepsin A, and \u03b1-l-Fucosidase). Altogether, this work advances our understanding of the cellular consequences following prolonged ASO administration and may guide further investigations to characterize these effects.\n\nID: 42560011\nTitle: Molecular switches of SQSTM1: the impact of post-translational modifications on autophagy and neurodegeneration.\nAbstract: SQSTM1/p62 (sequestosome 1) is an important receptor protein involved in many cellular signaling processes, including macroautophagy/autophagy. It is a molecular hub for cellular homeostasis and cellular responses. Within autophagy, SQSTM1 targets ubiquitinated cargo for degradation, maintaining cellular proteostasis. Structurally, SQSTM1 consists of several domains that facilitate its binding to ubiquitinated cargo, the formation of SQSTM1 aggregate inclusions, interactions with MAP1LC3/LC3, and the mediation of clearance via the autophagy pathway. Beyond its structure, post-translational modifications of SQSTM1 dynamically regulate its function within a cell. Post-translational modifications - such as phosphorylation, ubiquitination, acetylation, S-acylation, and S-nitrosylation - are crucial for regulating SQSTM1 function, localization, and interaction with autophagic components, thereby influencing SQSTM1's role in the autophagy pathway. Understanding the role of these protein modifications in modulating autophagy may provide better insight into developing therapeutic strategies for diseases with dysregulated autophagy, such as neurodegenerative diseases. This review will discuss the role of these post-translational modifications in controlling SQSTM1's localization and function in autophagy.Abbreviations: ABHD = \u03b1/\u03b2-hydrolase domain; AD = Alzheimer Disease; ALS = amyotrophic lateral sclerosis; ATG = autophagy related ; CSNK2/CK2 = casein kinase 2; HD = Huntington Disease; HDAC/KDAC = histone deacetylase/lysine deacetylase; HTT = huntingtin; KAT = lysine acetyltransferase; KEAP1 = kelch like ECH associated protein 1; KIR = KEAP1-interacting region; LIR = LC3-interacting region; LYPLA/APT = lysophospholipase/acyl-protein thioesterase; MAP1LC3/LC3 = microtubule associated protein 1 light chain 3; MEF = mouse embryonic fibroblast; mHTT = mutant huntingtin; MTORC1 = MTOR complex 1; NBR1 = NBR1 autophagy cargo receptor; NEDD4 = NEDD4 E3 ubiquitin protein ligase ; NO = nitric oxide; NFE2L2/Nrf2 = nuclear factor erythroid 2-factor 2; PAT = palmitoyl acyltransferase; PB1 = Phox-BEM1 domain; PE = phosphatidylethanolamine; PLEKHM1 = pleckstrin homology and RUN domain containing M1; PLK2 = polo like kinase 2; PRKA/PKA = protein kinase cAMP-activated; PPT1 = palmitoyl-protein thioesterase 1; RB1CC1 = RB1 inducible coiled-coil 1; SNCA/\u03b1-synuclein = synuclein alpha; SNO = S-nitrosothiol; SOD1 = superoxide dismutase 1; SQSTM1 = sequestosome 1; TARDBP/TDP-43 = TAR DNA binding protein ; TBK1 = TANK binding kinase 1; TAX1BP1 = Tax1 binding protein 1; TRIM = tripartite motif containing ; UBA = ubiquitin-associated domain; UBE = ubiquitin-conjugating enzyme; ULK1 = unc-51 like autophagy activating kinase 1; UPS =ubiquitin-proteasome system; USP8 = ubiquitin specific peptidase 8; ZDHHC = zDHHC palmitoyltransferase.\n\nID: 42556751\nTitle: Intranasal Pacritinib-loaded nanoemulsion for Glioblastoma management: In Vitro, ex Vivo, 3D spheroid and In vivo brain biodistribution studies.\nAbstract: Pacritinib (PAC), a potent inhibitor of JAK2, is currently being explored as a potential therapeutic agent against GBM, which is an aggressive and vascularized brain tumor, resistant to many therapies. The therapeutic potential of PAC is hindered due to its poor water solubility and low brain bioavailability. In the current study, a PAC-loaded nanoemulsion (PAC-NE) was formulated to deliver the drug through the intranasal (IN) route for better solubilization, nasal absorption, and brain targeting. The optimized formulation of PAC-NE exhibited a mean droplet size of 18.78\u202f\u00b1\u202f0.4\u202fnm and a polydispersity index (PDI) value of 0.183\u202f\u00b1\u202f0.007, representing a highly homogenous and uniform NE, which is appropriate for nasal administration. In vitro evaluation of the anticancer efficacy in 2D cell culture and 3D tumor spheroid model (3DS) proved that PAC-NE greatly improved the cellular uptake, cytotoxicity, and tumor spheroid inhibition activity compared with free PAC. In addition, ex vivo nasal permeation was greatly improved by the optimized formulation, showing a flux value of 1.27\u202f\u00b1\u202f0.06\u202f\u00b5g/cm2/h and a permeability coefficient value of 2.4\u202f\u00d7\u202f10\u207b7\u202f\u00b1\u202f0.19\u202fcm/s, which were significantly higher than that of the plain drug. Moreover, the histopathological examination demonstrated no sign of damage to the nasal mucosa. Pharmacokinetics analysis following IN application revealed that the optimized NE depicted greater brain-targeting ability, where there was an improvement in %DTE by 1.99-fold and in %DTP by 2.75-fold in comparison to free PAC. Overall, from the above observations, it can be concluded that PAC-NE is a non-invasive delivery system which shows promising results for better brain delivery thereby supporting the clinical translation of PAC for GBM therapy.\n\nID: 42548880\nTitle: Dapagliflozin and cognitive impairment: pharmacological mechanisms, translational evidence, and future directions.\nAbstract: Cognitive impairment increasingly emerges at the intersection of type 2 diabetes mellitus, vascular brain injury, chronic kidney disease, heart failure, and neurodegeneration, prompting interest in therapies that modify shared metabolic and inflammatory drivers of brain vulnerability. Dapagliflozin, a sodium-glucose cotransporter 2 inhibitor widely used in type 2 diabetes and cardiorenal disease, has attracted attention as a candidate modulator of cognitive decline because its established peripheral pharmacology extends beyond glucose lowering to include natriuresis, blood pressure reduction, weight loss, improved insulin resistance, reduced oxidative and inflammatory stress, and favorable cardiorenal effects. In this review, we examine the pharmacological basis by which these systemic actions could influence the neurovascular unit, mitochondrial homeostasis, glial activation, autophagy-related signaling, and synaptic plasticity pathways implicated in cognitive impairment. We summarize preclinical evidence suggesting that dapagliflozin can improve cognitive performance and modulate pathways such as AMPK-mTOR, Wnt/\u03b2-catenin, CREB/BDNF, oxidative stress responses, and neuroinflammatory signaling in experimental models, while also critically evaluating the limitations of these models. We then assess the current human evidence, distinguishing observational studies that suggest lower dementia risk from randomized clinical evidence that has not yet established a definitive cognition-related benefit. We argue that dapagliflozin should currently be viewed not as a proven cognitive therapeutic, but as a mechanistically plausible metabolic-neurovascular intervention whose relevance may be greatest in metabolically vulnerable phenotypes. Finally, we outline key translational challenges, including uncertainty regarding direct central target engagement, the need for biomarker-enriched trial designs, and the importance of integrating pharmacological, vascular, and neurodegenerative frameworks in future studies.\n\nID: 42548587\nTitle: Autophagy in ischemic stroke: pathophysiology, therapeutics, and challenges ahead.\nAbstract: Autophagy is a fundamental cellular homeostatic process that exerts a dual, context-dependent influence on the pathophysiology of ischemic stroke. Functioning as both a neuroprotective survival mechanism and a neurotoxic pathway, autophagy presents a complex therapeutic challenge as well as a potential target for molecular intervention. This narrative review synthesizes preclinical and emerging clinical evidence to summarize key mechanisms regulating autophagy in ischemic injury, evaluate therapeutic strategies, and identify promising molecular pathways and druggable targets for translational development. In the early ischemic phase, moderate autophagic activation facilitates neuronal survival by clearing damaged mitochondria and protein aggregates, thereby reducing oxidative stress and modulating neuroinflammation. This protective response is primarily mediated by regulators such as Beclin-1, the conversion of LC3-I to LC3-II, and the energy-sensing AMP-activated protein kinase pathway. Conversely, sustained or excessive autophagy, particularly during late-stage reperfusion, exacerbates neuronal injury through impaired lysosomal fusion, autophagosome accumulation, and the triggering of autophagic cell death and ferroptosis. Preclinical evidence highlights a critical Goldilocks zone of activation, suggesting that therapeutic success hinges on maintaining autophagic flux within narrow physiological limits. Advancing these therapies into clinical practice requires precise spatiotemporal modulation, potentially as an adjunct to mechanical thrombectomy, as well as the development of robust, real-time biomarkers. A comprehensive understanding of the molecular and genetic determinants of autophagy, including sex-specific responses, is essential to bridge the translational gap and establish autophagy as a viable target for precision stroke medicine.\n\nID: 42546981\nTitle: New insights on microglial lysosomal acidification: A therapeutic target of neurodegenerative diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), maintain brain homeostasis and respond to pathological insults. Microglial dysfunction has been implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Impaired lysosomal function, particularly defective lysosomal acidification, leads to the accumulation of undegraded material, thereby promoting neuroinflammation and neuronal damage. This review examines the mechanisms governing lysosomal acidification in microglia and evaluates its potential as both a therapeutic target and a prognostic biomarker in neurodegenerative diseases. The literature on microglial lysosomal acidification, lysosomal pH regulation, autophagy, and neurodegeneration was searched in PubMed, Scopus, and Web of Science. Relevant mechanistic, preclinical, and translational studies were critically appraised and synthesized. Lysosomal acidification is increasingly recognized as a key regulator of microglial function and homeostasis. Defective acidification, driven by dysregulation of the vacuolar H+-ATPase (V-ATPase) proton pump, TFEB/TFE3 signaling pathways, and lysosomal ion channels such as TRPML1 and TMEM175, impairs autophagic flux and substrate degradation, facilitating the accumulation of neurotoxic aggregates including amyloid-\u03b2 and \u03b1-synuclein. Emerging evidence suggests that the degree of microglial lysosomal acidification may serve as a prognostic biomarker for disease progression and therapeutic response. Restoration or enhancement of lysosomal acidification through pharmacological modulation of lysosomal pH, activation of autophagy, or targeting of key regulatory pathways has been shown to re-establish microglial homeostasis, attenuate neuroinflammation, and confer neuroprotection in preclinical models. Restoration of microglial lysosomal acidification represents a promising therapeutic strategy for neurodegenerative diseases. A deeper understanding of the molecular mechanisms regulating lysosomal acidification in microglia may facilitate the identification of novel biomarkers and therapeutic targets, ultimately contributing to the development of innovative interventions for neurodegenerative disorders.\n\nID: 42546774\nTitle: Catalpol protects against MPP+-induced neurotoxicity by targeting PINK1/DJ-1-mediated mitophagy and the TrkB/Akt/BDNF/Bcl-2 axis.\nAbstract: Parkinson's disease (PD) is a prevalent neurodegenerative disorder characterized by dopaminergic neuronal death of unclear etiology. While levodopa remains the gold standard for managing PD motor symptoms, it lacks disease-modifying efficacy, necessitating new neuroprotective therapies. Mitochondrial dysfunction and impaired autophagy are key hallmarks of PD. This study utilized 1-methyl-4-phenylpyridinium (MPP+)-treated SH-SY5Y cells to investigate the neuroprotective mechanisms of catalpol, an iridoid glycoside derived from Rehmannia glutinosa. We found that catalpol attenuated MPP+-induced neurotoxicity, mitochondrial membrane depolarization, and ATP depletion. This protection was critically dependent on autophagy; it was enhanced by the activator rapamycin but abolished by the inhibitor wortmannin and the autophagosome-lysosome fusion inhibitor bafilomycin A1. Catalpol activated autophagy by increasing autophagosome formation, elevating Beclin 1 and LC3-II levels, and promoting p62 degradation. Furthermore, catalpol reversed MPP+-induced mitophagy suppression and restored the regulatory protein PINK1 and DJ-1 expression. Given that Akt/BDNF/Bcl-2 and TrkB/BDNF pathways promote neuronal survival, we investigated their involvement. We found that the TrkB agonist 7,8-DHF mimicked catalpol's neuroprotection against MPP+-induced neurotoxicity, whereas the pan-Trk inhibitor GNF-5837 abolished it. Western blotting demonstrated that catalpol reversed MPP+-mediated suppression of TrkB and Akt phosphorylation, as well as BDNF and Bcl-2 expression. Molecular docking indicated that catalpol may interact with the TrkB ligand-binding domain as 7,8-DHF and shares key binding residues. Our findings suggest that catalpol exerts neuroprotection via a dual mechanism: preserving mitochondrial function through PINK1/DJ-1-mediated mitophagy and activating the TrkB/Akt/BDNF/Bcl-2 survival pathway, potentially by interacting with the TrkB receptor, highlighting its therapeutic potential for PD.\n\nID: 42544642\nTitle: Microneedling-assisted Panax ginseng exosome protocol for vulvovaginal symptoms and vulvar skin tone changes: A preliminary pilot observational study.\nAbstract: BackgroundNonhormonal approaches for vulvovaginal symptoms and vulvar skin concerns are increasingly being explored. However, clinical evidence for combined microneedling-assisted topical protocols in this setting remains limited.ObjectivesThis preliminary pilot observational study explored the short-term feasibility, patient-reported outcomes, tolerability, and qualitative photographic findings associated with a combined microneedling-assisted Panax ginseng exosome protocol with adjunctive inner gel use.DesignSingle-arm preliminary pilot observational study.MethodsFourteen women (mean age, 48.6 years; range, 24-63 years) underwent three treatment sessions at 2-week intervals, followed by a final assessment 2 weeks after the third treatment session, resulting in a total study duration of 6 weeks from baseline to final follow-up for each participant. Microneedling was performed on the vulvar area using a 2-mm dermaroller, followed by topical application of a Panax ginseng exosome formulation. Participants also used an adjunctive inner gel between visits. Outcomes included the Vulvovaginal Symptom Questionnaire (VSQ), the Day-to-Day Impact of Vaginal Aging (DIVA) questionnaire, procedural pain assessed using a visual analogue scale (VAS), safety observations, and qualitative clinical photographic assessment.ResultsTotal VSQ score decreased after treatment (mean change, -2.86; 95% confidence interval [CI], -4.76 to -0.95; p = 0.00648). Total DIVA score also decreased (mean change, -5.43; 95% CI, -9.55 to -1.30; p = 0.0138), with significant improvement in the daily activities domain (median change, -2.0; p = 0.00849). The emotion and sexual life domains showed directional decreases but did not reach statistical significance. Procedure-related pain was transient and generally decreased within 30 minutes after treatment. Clinical photographs showed qualitative observational changes in pigmentation intensity and skin tone uniformity. No serious adverse events were observed during the short follow-up period.ConclusionThis small uncontrolled pilot study found that the combined microneedling-assisted Panax ginseng exosome protocol with adjunctive inner gel use was associated with short-term improvements in patient-reported vulvovaginal symptoms and qualitative vulvar skin tone observations. Because of the single-arm design, small sample size, combined intervention, subjective photographic assessment, and short follow-up, these findings should be interpreted as preliminary and hypothesis-generating. Many women experience vulvovaginal symptoms such as dryness, itching, irritation, discomfort, or pain during sexual activity. Some women also have concerns about changes in vulvar skin tone. This small pilot study looked at a combined nonhormonal treatment using microneedling, a topical Panax ginseng exosome product, and home use of an inner gel. Fourteen women took part. Each participant received three treatment sessions, 2 weeks apart, and had a final assessment 2 weeks after the third session. The total study duration was 6 weeks. After treatment, participants reported lower vulvovaginal symptom scores and lower daily impact scores. The daily activities score improved, while emotional well-being and sexual life scores showed decreasing trends but did not significantly improve. Treatment-related pain was temporary and generally decreased within 30 minutes. No serious adverse events were observed during the short follow-up period. Clinical photographs showed visual changes in skin tone in some cases, but these photographs were not measured using objective color tests or blinded grading. Because this study included only 14 participants, had no control group, used a combined treatment, and had short follow-up, the findings should be considered preliminary. Larger controlled studies are needed to confirm safety, durability, and clinical usefulness.\n\nID: 42542064\nTitle: Integrating UHPLC-HRMS with SSA-BP neural network identifies optimal components of Astragali Radix\u2011Salviae Miltiorrhizae combination for mitigating cerebral ischemia-reperfusion injury via mitophagy and ferroptosis pathways.\nAbstract: Astragali Radix (Huangqi) and Salvia miltiorrhiza (Danshen) represent a frequently paired herbal combination in traditional Chinese medicine for tonifying Qi and promoting blood circulation. Previous pharmacological investigations have shown that phytochemicals derived from these herbs exhibit neuroprotective properties against cerebral ischemia-reperfusion (CI/R) injury. Nevertheless, the underlying principles governing the combined application of Huangqi and Danshen (QD) and the molecular pathways involved in their therapeutic efficacy remain unexplored in ischemic stroke management. This study sought to systematically investigate the bioactive components in the QD formulation and elucidate their mechanisms of action against cerebral ischemic injury. The therapeutic effects of QD were evaluated in a mouse model of middle cerebral artery occlusion (MCAO). UHPLCHRMS was used to identify QD-derived components in blood and brain tissues. An SSA-BP neural network was constructed to predict the optimal combination of active ingredients. 4D label-free proteomics, coupled with GO and KEGG enrichment analyses, was performed to identify key pathways. Molecular docking and molecular dynamics simulations were used to validate candidate targets. Mitochondrial function and iron homeostasis were assessed by measuring ROS, mitochondrial membrane potential (\u0394\u03a8m), ATP, complex I activity, Fe2+, and the GSH/GSSG ratio. Western blotting and immunofluorescence were used to detect FUNDC1, Nrf2, SLC7A11, NCOA4, p62, FTH1, UQCRC2, and GPX4. The autophagy inhibitor 3-MA was used for mechanistic validation. For cellular studies, HT22 cells were subjected to oxygen-glucose deprivation/reoxygenation (OGD/R), and QD was added during reoxygenation. Cell viability and cytotoxicity were assessed using CCK-8 and LDH assays, respectively. ROS, \u0394\u03a8m, Fe2+, and GSH were measured using commercial kits. Western blotting was used to analyze FUNDC1, UQCRC2, LC3-II/I, p62, GPX4, SLC7A11, NCOA4, Nrf2, and FTH1. siFUNDC1 was transfected 48 h before OGD/R to assess FUNDC1 dependency. Among the tested ratios (1:1, 2:1, 3:1, 3:2, and 2:3), the 3:2 QD combination was the most effective, significantly improving neurological function, reducing infarct size, and alleviating neuronal damage in MCAO mice. UHPLCHRMS identified 21 compounds absorbed into the bloodstream, seven of which were detected in brain tissue. Astragaloside IV, astragaloside II, lithospermic acid, tanshinone IIA, and calycosin were identified as key active components. Their combination, predicted by the SSA-BP neural network, exerted significant neuroprotection in vivo. Proteomics revealed 124 differentially expressed proteins, with GO and KEGG enrichment analyses identifying mitophagy and ferroptosis as the primary therapeutic pathways. Molecular docking and dynamics analyses revealed high-affinity binding interactions between QD constituents and key targets, including FUNDC1, UQCRC2, GPX4, and SLC7A11. QD upregulated FUNDC1, UQCRC2, GPX4, SLC7A11, Nrf2, and FTH1 and downregulated p62 and NCOA4; these effects were partially reversed by 3-MA. In HT22 cells, QD improved cell viability, reduced LDH release, restored \u0394\u03a8m and GSH levels, and attenuated ROS and Fe\u00b2\u207a accumulation following OGD/R. The protein expression changes were consistent with those observed in vivo. Knockdown of FUNDC1 largely blocked the protective effects of QD, confirming that FUNDC1 is essential for QD-mediated neuroprotection. QD ameliorates MCAO-induced cerebral ischemic injury via mitophagy and ferroptosis pathways, offering a novel therapeutic perspective for treating ischemic stroke with traditional Chinese medicine that tonifies Qi and promotes blood circulation.\n\nID: 42541636\nTitle: The Glial Autophagy-Lysosomal-Inflammation Axis in Alzheimer's Disease: a Unifying Mechanistic Framework.\nAbstract: Recent studies suggest that impairment of the glial autophagy-lysosomal pathway (ALP) critically contributes to the sustained neuroinflammatory response and neurodegenerative processes in Alzheimer's disease (AD). Glial cells, comprising microglia, astrocytes, oligodendrocytes, and ependymal cells, serve as key immune regulators in the central nervous system, where they are essential for maintaining ALP homeostasis, promoting proteostasis, and modulating neuroinflammatory responses. Here, we systematically review the regulatory roles of glial ALP in AD pathology, emphasizing its involvement in amyloid accumulation, tau hyperphosphorylation, synaptic impairment, white matter damage, and mitochondrial as well as other organelle dysfunction, and provide an in-depth analysis of key signaling pathways including TFEB, mTOR, and NLRP3. Furthermore, we outline therapeutic strategies aimed at restoring lysosomal function, regulating autophagic flux, and suppressing inflammation, along with a discussion of the multi-target regulatory potential of acupuncture and natural bioactive agents. We also highlight emerging ALP-associated biomarkers and their potential utility in early diagnosis and treatment response assessment. The objective of this review is to uncover the mechanistic interplay between glial ALP dysregulation and the pathological cascade of AD, offering a conceptual framework for the development of novel therapeutics that integrate neuroprotection with immune modulation.\n\nID: 42541586\nTitle: Research progress of traditional Chinese medicine interventions for aging-related nervous system diseases.\nAbstract: Aging-related neurological disorders, including stroke, Alzheimer's disease (AD), Parkinson's disease (PD), epilepsy, and various neuroinflammatory conditions, affect over three billion individuals worldwide and constitute leading causes of morbidity, disability, and socioeconomic burdens. Aging contributes not only to the increased incidence of these disorders but also to their progression through interconnected mechanisms, including endothelial dysfunction, oxidative stress, chronic inflammation, mitochondrial dysfunction, cellular senescence, metabolic imbalance, and gut microbiota dysbiosis. These processes collectively impair neuronal survival, synaptic plasticity, and cognitive and motor functions. Traditional Chinese medicine (TCM), with its characteristic multi-component and multi-target therapeutic strategies, has emerged as a promising approach to counteract age-associated neurological decline. Accumulating preclinical studies suggest that TCM interventions may exert neuroprotective, anti-inflammatory, and antioxidant effects, modulate autophagy, restore metabolic homeostasis, and potentially delay cellular senescence. However,\u00a0high-quality clinical evidence on safety and efficacy remains limited. This review summarizes current insights into the molecular interplay between aging and neurological disorders and highlights the therapeutic potential of TCM in targeting hallmarks of aging, providing perspectives for integrative prevention and treatment strategies for neurodegenerative and neurovascular diseases.\n\nID: 42541426\nTitle: Neuroprotective Potential of Spermidine in Drosophila sws Neurodegenerative Model.\nAbstract: Neurodegenerative disorders are characterized by progressive neuronal loss and functional decline, yet effective interventions remain limited. The polyamine spermidine was suggested to exert neuroprotective effects, but its concentration-dependent impact on longevity, neuronal integrity, and behavior remains still not well studied. Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC). Our results suggest that spermidine at low doses has the potential to be a general-purpose neuroprotector.\n\nID: 42539249\nTitle: KIF1A-mediated trafficking is required for neuronal autophagy in human neurons.\nAbstract: Mutations in the molecular motor protein KIF1A result in a spectrum of neurodevelopmental and neurodegenerative disorders termed KIF1A-Associated Neurological Disorder (KAND). KIF1A mutations variably disrupt synaptic vesicle trafficking, but the effects of KIF1A mutations on other trafficking pathways remain unexplored. Autophagy is a conserved pathway required for neuronal homeostasis. We investigated the role of KIF1A in autophagy using gene-edited human IPSC-derived neurons. KIF1A loss inhibited the trafficking of ATG9, a transmembrane lipid scramblase necessary for autophagosome biogenesis. This deficit significantly reduced autophagosome biogenesis and the density of axonal autophagosomes. KIF1A loss also depleted lysosomes from the axon, inhibiting autophagosome maturation. In neurons gene-edited to heterozygously express a pathogenic variant linked to a Rett-like syndrome in KAND patients, we also noted significant deficits in autophagy and lysosomal trafficking. Together, these results suggest that KIF1A-mediated transport is critical to neuronal autophagy and that deficits in autophagy may contribute to pathogenesis in KAND.\n\nID: 42538987\nTitle: GENETIC AND PHARMACOLOGIC ACTIVATION OF BECLIN1 PREVENTS ALDOSTERONE-INDUCED CARDIOVASCULAR DAMAGE.\nAbstract: Aldosterone promotes endothelial dysfunction and cardiovascular injury through mineralocorticoid receptor (MR) activation. Autophagy is essential for endothelial homeostasis, yet its role in aldosterone-mediated vascular dysfunction remains unclear. We tested whether aldosterone impairs autophagic flux and whether restoring autophagy via Beclin1 (BCN1) activation protects vascular and cardiac function. Endothelial and vascular responses to aldosterone were assessed in wild-type mice, BCN1 gain-of-function mice (Becn1), and mice treated with spermidine or a BCN1-activating TB-peptide. Vascular function, nitric oxide (NO)/reactive oxygen species (ROS) production, autophagy markers, endothelial migration, and cardiac fibrosis were evaluated using wire myography, fluorescence assays, Western blotting, confocal microscopy, migration assays, and histology. Aldosterone impaired endothelium-dependent relaxation, decreased NO, increased ROS, and disrupted autophagic flux in an MR-dependent manner, indicated by LC3 accumulation and reduced p62 and BCN1 expression. Spermidine restored endothelial function and normalized NO and ROS levels. BCN1 gain-of-function mice were protected from aldosterone-induced endothelial dysfunction and exhibited reduced coronary and myocardial fibrosis. TB-peptide activation of BCN1 enhanced autophagic flux, improved vascular function, decreased cardiac fibrosis, and rescued endothelial migration impaired by aldosterone. Aldosterone induces endothelial dysfunction by suppressing autophagic flux through MR activation. Genetic or pharmacologic enhancement of BCN1-dependent autophagy restores endothelial homeostasis and prevents vascular and cardiac injury, identifying autophagy activation as a promising therapeutic approach for cardiovascular diseases associated with mineralocorticoid excess.\n\nID: 42538520\nTitle: The Pleiotropic Therapeutic Perspectives of GLP-1 and GIP Receptor Agonists in Spinal Cord Injury: A Narrative Review.\nAbstract: Spinal cord injury (SCI) constitutes a major global health challenge. The pathophysiology of SCI involves many aspects. Current treatments, such as early decompression and glucocorticoids, target single pathways and show limited efficacy with safety concerns. In this context, interventions based on the incretin system are now considered attractive candidates for SCI intervention. This review comprehensively outlines the mechanisms underlying microenvironmental imbalance following SCI and explores glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists as promising options. These agents, recognized for their role in managing diabetes and body weight, demonstrate substantial pleiotropic effects beyond simple glycemic regulation. These beneficial actions include neuroprotection, anti-inflammatory effects, and the promotion of tissue repair. Preclinical SCI studies have indicated that GLP-1 receptor agonists and GIP receptor agonists reduce inflammation by shifting microglia/macrophages to anti-inflammatory phenotypes, suppress apoptosis, increase autophagy, alleviate oxidative stress, promote axonal regeneration, improve the injury microenvironment, and have the potential to regulate immune cells. Related research in other neurological disorders supports these mechanisms, with dual agonists showing superior efficacy. GLP-1 receptor agonists and GIP receptor agonists suggest significant potential to address the multifaceted pathology and associated metabolic complications of SCI. Current evidence highlights the importance of mechanistic elucidation, dose optimization, the development of innovative delivery systems such as nanoparticles, and further validation in large animal and human studies.\n\nID: 42538401\nTitle: Intermittent fasting: Impact, mechanisms and cautions across medical and lifestyle domains.\nAbstract: Intermittent fasting (IF) has emerged as a promising dietary approach with prospective advantages for clinical as well as non-clinical applications. Research indicates that IF enhances insulin sensitivity, facilitates weight reduction and stimulates cellular repair pathways, including autophagy. Physiological adaptations to fasting are reflected in favorable alterations in biomarkers and metabolic processes. This review examines the current evidence on IF by analyzing studies retrieved through schematic searches of the MEDLINE via PubMed database, Embase and ScienceDirect using specific keyword combinations. It focuses on commonly practiced regimens- Time-restricted eating (TRE) (16/8 method), Alternate-day fasting (ADF), the 5:2 intermittent energy-restriction diet and One meal a day (OMAD) approaches and explores their effects on cardiovascular function, metabolic regulation, cognitive performance and longevity. Various IF regimens including the TRE (16/8 method), ADF, the 5:2 diet and OMAD approaches are discussed in relation to their effects on cardiovascular health, cognitive function, metabolic regulation, aging and longevity. While most finding highlight significant health benefits, inconsistencies and methodological limitations are also reported. Mechanistically, IF orchestrates a coordinated metabolic response through modulation of key nutrient sensing pathway such as AMP activated protein kinase (AMPK), mechanistic target of rapamycin (mTOR) and unc-51-like kinase 1 (ULK1). These cascades interact with Sirtuins (SIRT1/3), peroxisome proliferator activated receptor gamma coactivator-1\u03b1 (PGC-1\u03b1) and the transcription factor EB (TFEB) to regulate autophagy, mitochondrial biogenesis, oxidative stress defense and cellular repair. Clinically, these molecular events underpin improvements in glycaemic control, lipid metabolism and inflammatory balance, supporting the therapeutic potential of IF for cardiometabolic disorders, neuroprotection and healthy aging.\n\nID: 42533617\nTitle: Mitophagy in neurodegeneration: crosstalk between PRKN/parkin-dependent and PRKN-independent pathways.\nAbstract: Mitochondrial quality control is essential for cellular homeostasis, particularly in neurons, where mitochondrial dysfunction is implicated in the pathogenesis of neurodegenerative diseases. Mitophagy, the selective degradation of damaged or superfluous mitochondria, plays a central role in maintaining mitochondrial integrity and metabolic balance. This review provides a comprehensive overview of the best-characterized PINK1-PRKN/parkin-dependent mitophagy pathway and the expanding repertoire of PRKN-independent mechanisms, including additional ubiquitin-dependent, receptor-mediated, and lipid-mediated pathways. We explore how these pathways intersect and compensate for one another, highlighting the complexity and adaptability of mitochondrial quality control networks. Furthermore, we discuss how dysregulated mitophagy contributes to the onset and progression of neurodegenerative diseases. By examining the interplay between mitophagy pathways and their regulation under physiological and pathological conditions, this review underscores the therapeutic potential of targeting mitophagy in neurodegeneration. Future studies should aim to decode the spatiotemporal dynamics of these pathways to uncover novel opportunities for clinical intervention.Abbreviations: AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; AMBRA1: autophagy and beclin 1 regulator 1; AMFR/GP78: autocrine motility factor receptor; AMPK: AMP-activated protein kinase; ARIH1: ariadne RBR E3 ubiquitin protein ligase 1; ATG: autophagy related; A\u03b2: amyloid beta; BCL2L13: BCL2 like 13; BNIP3: BCL2 interacting protein 3; BNIP3L/NIX: BCL2 interacting protein 3 like; CALCOCO2/NDP52: calcium binding and coiled-coil domain 2; CAMc: core autophagy machinery components; CSNK2/CK2: casein kinase 2; DUB: deubiquitinase; DNM1L/DRP1: dynamin 1 like; FKBP8: FKBP prolyl isomerase 8; FUNDC1: FUN14 domain containing 1; GABARAP: GABA type A receptor-associated protein; GLP-1: glucagon-like peptide 1; HD: Huntington disease; HUWE1: HECT, UBA and WWE domain containing E3 ubiquitin protein ligase 1; IMM: inner mitochondrial membrane; iPSC: induced pluripotent stem cell; LIR: LC3-interacting region; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARCHF5: membrane associated ring-CH-type finger 5; MCL1: MCL1 apoptosis regulator, BCL2 family member; MDV: mitochondria-derived vesicle; MFN1: mitofusin 1; MFN2: mitofusin 2; MQC: mitochondrial quality control; mtDNA: mitochondrial DNA; MUL1: mitochondrial E3 ubiquitin protein ligase 1; NBR1: NBR1 autophagy cargo receptor; OMM: outer mitochondrial membrane; OMMAD: outer mitochondrial membrane-associated degradation; OPA1: OPA1 mitochondrial dynamin like GTPase; OPTN: optineurin; OXPHOS: oxidative phosphorylation; PARL: presenilin associated rhomboid like; PD: Parkinson disease; PE: phosphatidylethanolamine; PG: phagophore; PGAM5: PGAM family member 5, mitochondrial serine/threonine protein phosphatase; PINK1: PTEN induced kinase 1; PPARGC1A/PGC-1\u03b1: PPARG coactivator 1 alpha; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PtdIns3K: phosphatidylinositol 3-kinase; RB1CC1/FIP200: RB1 inducible coiled-coil 1; RHOT1/Miro1: ras homolog family member T1; ROS: reactive oxygen species; SIAH1: siah E3 ubiquitin protein ligase 1; SMURF1: SMAD specific E3 ubiquitin protein ligase 1; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TAX1BP1: Tax1 binding protein 1; TBK1: TANK binding kinase 1; TCA: tricarboxylic acid cycle; TFAM: transcription factor A, mitochondrial; TIMM: translocase of inner mitochondrial membrane; TOMM: translocase of outer mitochondrial membrane; Ub: ubiquitin; ULK1: unc-51 like autophagy activating kinase 1; UPRmt: mitochondrial unfolded protein response; UPS: ubiquitin-proteasome system; USP30: ubiquitin specific peptidase 30; VCP: valosin containing protein; VDAC: voltage dependent anion channel; WIPI: WD repeat domain, phosphoinositide interacting.\n\nID: 42530260\nTitle: Neuroprotective Properties and Molecular Mechanisms of Action of 4H-Pyran-Based Acids.\nAbstract: The development of effective neuroprotective agents remains one of the most urgent and complex challenges in modern medical and biological research, given the increasing prevalence of neurodegenerative diseases and the limited efficacy of existing therapeutic options. In recent years, compounds belonging to the 4H-pyran chemical class have attracted significant attention due to their pronounced antioxidant, anti-inflammatory, and cytoprotective properties. These molecules exhibit structural versatility, enabling modulation of multiple molecular targets involved in neuronal survival, redox homeostasis, and mitochondrial function. This review provides a comprehensive analysis of the pharmacological activity and molecular mechanisms of action of five 4H-pyran-based compounds-maltol, kojic acid, chelidonic acid, comenic acid, and meconic acid. Special attention is paid to their effects on signaling pathways that play a central role in maintaining neuronal integrity and resistance to stress factors. In particular, the review examines how these compounds regulate key intracellular cascades such as nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1)/antioxidant response element (ARE), Nrf2/PTEN-induced putative kinase 1 (PINK1)/Parkin, nuclear factor-kappa B (NF-\u03baB), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR), which are critically involved in controlling oxidative stress, mitochondrial autophagy, inflammation, and neuronal plasticity. The integrated evaluation of these mechanisms demonstrates that 4H-pyran-based acids can act as multitarget neuroprotective agents capable of influencing both primary metabolic processes and secondary signaling responses to neurotoxic stimuli. Their pleiotropic action highlights the promise of these compounds as molecular scaffolds for the development of novel drugs aimed at preventing or delaying the progression of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases.\n\nID: 42530044\nTitle: Extracellular Vesicle-Mediated Delivery of VEGF and NGF Protects Dopaminergic Neurons in 6-OHDA-Induced Parkinson's Disease Models.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disorder marked by motor dysfunction. No definitive methods exist to repair damaged neurons. Vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) are two neuroprotective agents that work synergistically. However, these large molecular proteins have difficulty crossing the blood-brain barrier (BBB). Extracellular vesicles (EVs) offer superior targeting and low immunogenicity, making them excellent carriers. In this study we examined the protective effects of VEGF and NGF in a cell model and evaluated the therapeutic potential of VEGF-NGF contained within EVs in PD rats. EVs were isolated using sequential differential centrifugation and characterized using transmission electron microscopy, nanoparticle tracking analysis, and western blotting (WB). VEGF and NGF were loaded into the EVs using a saponin-assisted method to create VEGF@EVs, NGF@EVs, and VEGF/NGF@EVs. The viability of 6-hydroxydopamine hydrochloride (6-OHDA)-induced SH-SY5Y cells was measured using the cell counting kit-8 assay before and after treatment with VEGF and NGF. Autophagy levels were assessed using WB, and the role of autophagy was further explored using the autophagy inhibitor chloroquine. Unilateral PD rat models were established via stereotactic injection of 6-OHDA into male Sprague-Dawley rats. Behavioral changes were monitored before and after treatment. Neuronal recovery, neurotransmitter levels, and autophagy levels in the rat brains were evaluated using immunohistochemistry, enzyme-linked immunosorbent assay, and WB. VEGF/NGF@EVs significantly enhanced the viability of 6-OHDA-induced SH-SY5Y cells. A complete autophagic process was identified as essential for this protective effect. The intranasal administration of VEGF/NGF@EVs improved motor behavior in PD rats, with performance better than that of single growth factor treatments. The number of tyrosine hydroxylase (TH)-positive neurons, TH protein expression, and dopamine content were significantly increased. In addition, the level of autophagy in the rat substantia nigra was elevated. VEGF/NGF@EVs exert protective effects in both in vitro and in vivo 6-OHDA-induced PD models by promoting autophagy, demonstrating greater efficacy than either growth factor alone. By transplanting VEGF/NGF@EVs into PD rats, we showed that these vesicles can effectively cross the BBB and deliver targeted therapy to the central nervous system. This study highlights the significant potential of EV-mediated protein transplantation strategies for treating neurological disorders.\n\nID: 42529163\nTitle: The endo-lysosomal-lipid axis: bidirectional interactions between membrane trafficking dysfunction and lipid metabolic disorders.\nAbstract: The endo-lysosomal system is a central regulator of intracellular trafficking, cargo degradation, and metabolic homeostasis. Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities.\n\nID: 42524508\nTitle: Intranasal Biodegradable Nanomedicine for Epilepsy Management: Targeting the Brain Beyond the Blood-Brain Barrier.\nAbstract: Epilepsy is a common chronic neurological disorder characterized by recurrent, unprovoked seizures arising from abnormal neuronal hyperexcitability and hypersynchronous electrical activity within the brain. Despite advances in antiseizure medications, effective epilepsy management remains challenging because of pharmacoresistance, limited blood-brain barrier (BBB) permeability, inadequate intracerebral drug accumulation, and systemic toxicity. Moreover, currently available therapies primarily provide symptomatic seizure control without addressing the fundamental pathological processes involved in epileptogenesis, neuroinflammation, oxidative stress, and neuronal degeneration. Intranasal administration has emerged as an attractive non-invasive approach for direct brain targeting, enabling therapeutic agents to circumvent BBB-associated transport barriers and access the central nervous system through the olfactory and trigeminal neural pathways. In this context, biodegradable nanomedicine platforms have gained considerable attention due to their favorable biocompatibility, controlled drug release, enhanced mucosal permeation, and potential for targeted intracerebral delivery. This review provides a comprehensive and critical overview of recent advances in intranasal biodegradable nanomedicine for epilepsy, integrating current knowledge on disease pathophysiology, biological and pharmaceutical barriers, nose-to-brain transport mechanisms, biodegradable nanoparticle platforms, and emerging functionalization strategies. Importantly, the review critically evaluates the current evidence, distinguishing encouraging preclinical findings and discusses the major translational challenges that continue to hinder clinical implementation. Finally, future perspectives are highlighted to identify opportunities for developing safer, more effective, and clinically translatable therapies for epilepsy management.\n\nID: 42520939\nTitle: SNX-BAR proteins 5 and 6 are required for NCOA7-AS antiviral activity against influenza A virus.\nAbstract: Interferon-induced antiviral proteins act on the first line of defence against viruses, including influenza A virus (IAV). Among those, the short isoform of Nuclear Receptor Coactivator 7 (NCOA7-AS) has been shown to inhibit IAV entry and more especially the fusion between endosomal and viral membranes. Ectopic expression of NCOA7-AS leads to the increased acidification of the endolysosomal pathway, putatively through NCOA7-AS interaction with the vacuolar ATPase (V-ATPase). However, the precise mechanism of action of NCOA7-AS is not fully understood. Here, we identified the cellular partners of NCOA7-AS by mass spectrometry, including the V-ATPase subunits known to interact with NCOA7-AS. A point mutation disrupting the interaction with the V-ATPase led to loss of antiviral activity against IAV, demonstrating that V-ATPase engagement is required for the antiviral phenotype. Moreover, sorting nexin (SNX) 1/2/5/6 were identified as novel partners of NCOA7-AS. These proteins are involved in retrograde transport of cellular cargoes from endosomes to the trans-Golgi network. We revealed that SNX5/6 interacted directly with NCOA7-AS and were essential for NCOA7-AS antiviral activity against IAV. Interestingly, crystal structures of NCOA7-AS/SNX5 complexes showed that the SNX5-interaction motif in NCOA7-AS was similar to those found in known cargoes of SNX5/6. In addition, we could pinpoint several critical residues that were important for binding and antiviral activity. Collectively, our study identifies novel essential partners for NCOA7-AS antiviral activity and the structural basis for their interaction.\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: 42516551\nTitle: Gerstmann-Str\u00e4ussler-Scheinker syndrome with unexpected concomitant GRN variant: case report.\nAbstract: The objective is to report a patient with Gerstmann-Str\u00e4ussler-Scheinker syndrome caused by a pathogenic PRNP P102L variant harboring an unexpected concomitant pathogenic GRN variant p.R110X and to discuss the potential contribution of combined genetic pathology to the clinical and neuroimaging phenotype confirmed by autopsy. Moreover, we discuss the potential role of TMEM106B as an important modifier of the protein TDP-43 neuropathology associated with the GRN mutation in this case. The patient underwent detailed clinical assessment, serial neuropsychological evaluation, brain MRI, cerebrospinal fluid analysis, whole-exome sequencing, and next generation sequencing. A postmortem neuropathologic examination was performed to confirm the diagnosis. The patient presented slowly progressive paresthesia, cerebellar ataxia, dysarthria, and later cognitive and behavioral changes. Genetic testing revealed a heterozygous PRNP P102L variant and an unpenetrated GRN p.R110X variant; a protective TMEM106B polymorphism associated with TDP-43 pathology was also identified. Neuroimaging demonstrated progressive cerebellar and parietal atrophy with asymmetric left frontal opercular and insular involvement. The clinical course was dominated by a cerebellar GSS phenotype. The patient died 4 years after symptom onset. Neuropathology confirmed GSS, nevertheless without detectable TDP-43-associated neuropathology. This case highlights the diagnostic complexity of rare neurodegenerative disorders and illustrates that pathogenic variants may not influence phenotypic expression. Comprehensive genetic testing should be considered in atypical cases, as certain genetic variants may contribute to phenotypic variability and represent potential modifiers of phenotypic expression.\n\nID: 42511591\nTitle: Intracellular Crosstalk of the Gasotransmitter Trio (NO, CO, H2S) in Cardiovascular Health and Disease: From Molecular Signaling to Precision Gas Medicine.\nAbstract: Nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S) were once regarded solely as toxic environmental gases. However, accumulating evidence over the past several decades has established them as the three principal endogenous gasotransmitters that regulate a wide spectrum of physiological and pathological processes. Unlike conventional signaling molecules, gasotransmitters diffuse freely across biological membranes and exert potent biological effects through receptor-independent mechanisms, including redox-sensitive post-translational modifications and modulation of heme-containing proteins. Although the individual functions of NO, CO, and H2S have been extensively reviewed, emerging studies indicate that these gaseous mediators rarely operate in isolation. Instead, they form a highly integrated signaling network characterized by direct chemical interactions, reciprocal enzymatic regulation, and convergence upon common downstream pathways. In this mini-review, we propose the concept of a \"Gasotransmitter Trio Network,\" emphasizing the molecular crosstalk among NO, CO, and H2S as a fundamental determinant of cellular homeostasis. We first summarize the biosynthetic pathways and major signaling mechanisms of the gasotransmitter trio, including S-nitrosylation, persulfidation, and heme-dependent regulation. We then discuss recent advances revealing how interactions among these gases generate novel bioactive intermediates and coordinate redox signaling. Particular attention is given to the emerging roles of gasotransmitters in regulating ferroptosis, autophagy, and mitophagy by modulating iron metabolism, lipid peroxidation, mitochondrial quality control, and antioxidant defense systems. These findings support a unified framework in which gasotransmitters function as master regulators of cellular fate under conditions of physiological and pathological stress. Finally, we highlight recent progress in stimuli-responsive donors, CO-releasing molecules (CORMs), NO-releasing materials (NORMs), H2S donors, and advanced nanoplatforms that enable spatiotemporally controlled gas delivery. We propose that future therapeutic strategies will increasingly rely on programmable multi-gas systems that recapitulate endogenous gasotransmitter networks. Collectively, this review provides a systems-level perspective on gasotransmitter biology and outlines emerging opportunities for the development of precision gas medicine in cardiovascular, neurodegenerative, inflammatory, metabolic, and malignant diseases.\n\nID: 42596071\nTitle: An expanding role for ATG8s and ATG8 E3-like ligases in maintaining membrane integrity.\nAbstract: Endolysosomal membranes are frequently damaged by pathogenic stress associated with aging, infection, and neurodegeneration, and failure to repair such damage leads to inflammation and cell death. Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity.\n\nID: 42594755\nTitle: Shikonin inhibits bladder cancer progression by targeting deoxyribonuclease 2 to suppress reticulon 3-dependent endoplasmic reticulum autophagy.\nAbstract: Bladder cancer (BCa) is a prevalent urinary malignancy with unmet clinical therapeutic needs. Shikonin, a natural anti-tumor compound, exerts anti-BCa activity, yet its direct molecular target and underlying mechanism remain undefined. This study aimed to identify the direct target of shikonin in BCa and to elucidate the mechanism by which shikonin suppresses tumor progression. The anti-BCa effects of shikonin were assessed in vitro and in vivo. Drug affinity responsive target stability (DARTS) combined with 4D quantitative proteomics identified shikonin's direct target, which was validated by molecular docking and cellular thermal shift assay (CETSA). Gain- and loss-of-function experiments and ER-phagy-related assays elucidated the underlying molecular mechanism. Shikonin inhibited BCa cell proliferation, migration, invasion and induced senescence in vitro, and suppressed tumor growth in vivo with no obvious toxicity. Deoxyribonuclease 2 (DNASE2) was identified as shikonin's direct target; shikonin promoted DNASE2 ubiquitination and degradation without altering its mRNA level. DNASE2 was highly expressed in BCa and correlated with poor prognosis, and its knockdown mimicked and enhanced shikonin's anti-BCa effects. Mechanistically, shikonin targeted DNASE2 to downregulate Reticulon 3 (RTN3), thereby inhibiting RTN3-dependent endoplasmic reticulum autophagy (ER-phagy) in BCa. This study first identifies DNASE2 as the direct target of shikonin in BCa, and reveals that shikonin exerts anti-BCa activity by promoting DNASE2 ubiquitination/degradation to inhibit the DNASE2/RTN3 axis-mediated ER-phagy. The DNASE2/RTN3 axis is a novel ER-phagy regulatory node in BCa, providing a potential therapeutic target for BCa treatment.\n\nID: 42592647\nTitle: Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U-87 MG cells.\nAbstract: Glioblastoma (GBM) is a highly lethal brain cancer in which the calcitonin receptor (CT Receptor), encoded by the CALCR gene, is expressed in 78-88% of patient biopsies. Here, we investigate whether the CT Receptor plays a role in cancer cell survival. In cancer cell lines, knockdown of CALCR disrupts the cell cycle and induces apoptosis, supporting an essential pro-survival role. The CALCR gene produces three main transcripts in humans, of which Transcript 1 encodes CALCRb mRNA including exon 10 and is translated into the CTb Receptor isoform, and Transcripts 2 and 3 which are translated into the CTa Receptor. CALCRb expression is conserved across a diverse range of mammalian species. We examined the expression of all CT Receptor isoforms (CALCRtotal) and CALCRb expression in four high-grade glioma stem-like cell lines and in U-87 MG glioblastoma cells. Using qPCR, we observed stable levels of both CALCRtotal and CALCRb expression under conditions of autophagy or apoptosis, consistent with a requirement for CALCRb in cell survival. As alternative splicing (AS) of key genes in cancers confers tumour resilience, we investigated AS of CALCR transcript 2 using long-read nanopore sequencing. Unexpectedly, we discovered a novel AS event causing inclusion of exon 10 within Transcript 2 in all glioblastoma cell lines investigated. This finding, together with stable CALCRb expression under cellular stress and the finding by other groups confirming that knockdown of CT Receptor compromises cell survival, implicates the CTb Receptor as a potential oncoprotein.\n\nID: 42589605\nTitle: Conserved Core and Species-Specific Signatures in the Milk Exosomal microRNA Targetome: A Preliminary Comparative In Silico Analysis of Human, Cow, Goat and Donkey Milk.\nAbstract: Milk-derived extracellular vesicles (EVs) transport microRNAs (miRNAs) that are unusually stable and have been proposed to survive digestion and modulate gene expression in the consumer, although their dietary bioavailability and physiological relevance remain debated. How the predicted regulatory potential of these miRNAs differs among the milks of different animals most relevant to human nutrition has not been systematically compared. Here, we performed an integrative in silico analysis of publicly available small-RNA sequencing data from 29 milk and milk-cell samples of human, cow, goat, and donkey origin. miRNAs were quantified against human (hsa) miRBase references-thereby restricting the analysis to evolutionarily conserved miRNAs with human orthologs-and their predicted effect on the human transcriptome was modeled by integrating predicted (mirDIP database) and experimentally supported (TarBase v9 database) miRNA-target interactions into a per-gene, per-species weighted targeting score. Because miRNAs act predominantly as repressors, this score is read as a prediction of which genes would be post-transcriptionally down-regulated in a recipient. miR-148a-3p dominated the exosomal spectrum of all four species (human, cow, goat, and donkey; \u224821.5% of pooled abundance), and the twenty most abundant miRNAs accounted for roughly three quarters of the signal. Of 4577 robustly targeted genes, a 1809-gene conserved \"pan-milk\" core showed the highest cross-species targeting and was enriched for transcriptional regulation, PI3K-Akt, MAPK, and TGF-\u03b2/SMAD signaling, autophagy and-strikingly-the components of the RNA-interference machinery itself. Species-restricted gene sets recapitulated biologically plausible programs, including a human-biased neuronal/axon-guidance and chromatin module, a donkey-biased transcriptional, epithelial, and immune (CD47) module, and a ruminant lipid/cholesterol and insulin-mTOR module. Across categories, we observed a reproducible confidence-exclusivity trade-off. We emphasize that these results are computational predictions that assume dietary miRNA uptake and do not constitute experimental validation. We provide the complete targetome as a hypothesis-generating resource to prioritize candidate genes, pathways, and milk types for future functional, nutritional, and epigenetic investigation. Across the 29 samples from the four species, miRNA composition segregated by species (silhouette width = 0.82, a cluster-separation measure ranging from -1 to 1, with values near 1 indicating well-separated groups) and the category structure exceeded a permutation null, indicating that the between-species signal is robust to differences in dataset origin and milk state.\n\nID: 42589242\nTitle: Differential Effects of PERK and IRE1\u03b1 Silencing on Expression of Apoptosis and Autophagy Markers in T-Lymphoblastic Leukemia MOLT-3 Cells.\nAbstract: Cancer cells are able to survive under conditions of high endoplasmic reticulum (ER) stress by activating the adaptive unfolded protein response (UPR), which is closely linked with autophagy. On the other hand, excessive and prolonged ER stress leads to apoptosis. However, the relationships between different UPR branches and apoptosis or autophagy vary in cancer cells of different origins and depend on the extent and nature of the stress signal. This study was designed to establish the role of ER stress sensors protein kinase RNA-like endoplasmic reticulum kinase (PERK) and inositol-requiring enzyme 1 (IRE1\u03b1) in apoptosis or autophagy signaling in T-lymphoblastic leukemia MOLT-3 cells via the RNA interference method. The cells were transfected with small interfering RNAs (si-PERK, si-IRE1\u03b1, or si-Cont) for 6 h and further cultured under normal conditions for 72 h to provide an insight into chronic effects of the gene silencing. The expression of apoptosis and autophagy effectors at the mRNA and protein levels was compared using RT-PCR and Western blot assays, respectively. Transfection of the cells with PERK siRNA led to a significant decrease in PERK protein and gene expression, and decreased phosphorylation of its downstream effector eukaryotic initiation factor 2\u03b1 (eIF2\u03b1). PERK silencing was accompanied by activation of apoptosis-related genes and proteins-BCL2-associated X (Bax), caspase-3, C/EBP homologous protein (CHOP), while the levels of autophagy markers (Unc-51 like autophagy activating kinase 1 (ULK1), Beclin-1, and microtubule-associated proteins 1A/1B light chain 3 (LC3A/B)) remained stable. In contrast, treatment of the cells with si-IRE1\u03b1 reduced the content of IRE1\u03b1, X-box-binding protein 1 (sXBP1), and glucose-regulated protein 78 (GRP78) proteins, but increased ERN1 gene expression. IRE1\u03b1 RNA interference did not affect the levels of the pro-apoptotic marker Bax, but suppressed caspase-3, CHOP, c-Jun N-terminal kinase (JNK), and autophagy signaling molecules (ULK1, Beclin-1, LC3A/B) at both the transcriptional and translational levels. These results indicate that the PERK pathway is an important contributor to the survival of MOLT-3 cells under basal ER stress, while PERK depletion compromises the resistance of cells to UPR-mediated apoptosis. The IRE1\u03b1 UPR branch is directly linked with autophagy-dependent signaling, although IRE1\u03b1 knockdown exerted a more complicated influence on the cells, probably via activation of multiple pro-death and compensatory pro-survival regulatory mechanisms.\n\nID: 42589086\nTitle: SELENOT, a Key Membrane-Bound Selenoprotein, Mediates Selenium's Protection Against Lead-Induced Renal Aging in Chickens by Modulating Inflammation and Autophagy.\nAbstract: Lead (Pb) pollution is a global public health issue, yet the mechanisms underlying Pb-induced kidney aging remain poorly understood. Selenium (Se), an essential trace element critical for kidney health, primarily exerts its physiological roles via selenoproteins; among them, membrane-bound selenoproteins strategically localized at the endoplasmic reticulum and plasma membrane, have emerged as potential molecular links in Se-mediated protection. In this study, Hyline chicken models (treated with 350.00 mg/L Pb or/and 1.00 mg/kg Se) and HK-2 cell models (treated with 200 \u03bcM Pb or/and 2.5 \u03bcM Se) were established to investigate the protective mechanism of Se to Pb poisoning in kidneys, with emphasis on membrane-bound selenoproteins and kidney aging. Results showed that Pb significantly decreased (p < 0.05) membrane-bound selenoproteins and induced kidney aging. Inflammation and autophagy were involved, as Pb significantly increased (p < 0.05) pro-inflammatory cytokines interleukin-4 (IL-4) and interleukin-12\u03b2 (IL-12\u03b2), and autophagy-related genes autophagy related 5 (ATG5), BCL2 interacting coiled coil protein 1 (Beclin 1), and microtubule-associated protein 1A/1B-light chain 3 (LC3-II) while significantly suppressing (p < 0.05) interleukin-2 (IL-2) and mammalian target of rapamycin (mTOR). Se had a relieving effect on it, as evidenced by significantly reversing (p < 0.05) the changes in the above indicators. Interestingly, Selenoprotein T (SELENOT), as a hub membrane-bound selenoprotein, is sensitive to Pb poisoning (Pb exposure decreased SELENOT mRNA expression to 56%, 34%, and 19% of the control levels at 30, 60, and 90 days, respectively). Knockdown of SELENOT aggravated Pb-induced inflammation, autophagy, and cellular senescence, meaning that SELENOT protected against kidney aging via suppressing inflammation and autophagy under Pb stress. These findings establish membrane-bound selenoproteins as essential molecular hubs that orchestrate inflammation resolution and autophagy in Se's antagonism against Pb-induced kidney aging, highlighting promising therapeutic targets for nephropathy.\n\nID: 42587750\nTitle: The E. coli High-Pathogenicity Island Downregulates PI3K/Akt/mTOR Expression and Induces Autophagy in the Mouse Intestine.\nAbstract: The high-pathogenicity island (HPI) is a major virulence determinant in pathogenic Escherichia coli (E. coli), contributing to severe inflammation and tissue damage. Autophagy plays a critical role in clearing intracellular pathogens and modulating inflammation, but whether HPI manipulates this process remains unknown. Here, using a swine-pathogenic E. coli strain and its HPI-deficient mutant (\u0394irp2) generated by CRISPR/Cas9, we investigated the interplay between HPI and autophagy in RAW264.7 macrophages and a mouse intestinal infection model. We found that HPI+ infection induced autophagic activation, as evidenced by increased LC3 puncta (immunofluorescence), upregulated Beclin-1 and autophagy-related gene mRNA levels (qPCR), and downregulated phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) expression at both mRNA (qPCR) and protein (immunohistochemistry) levels. In a mouse model, HPI+ infection upregulated intestinal Microfold (M) cell markers and secretory Immunoglobulin A (IgA), triggered robust production of pro-inflammatory cytokines, and induced more severe tissue pathology than the HPI-deficient mutant. Pharmacological activation of autophagy with rapamycin alleviated HPI-induced inflammation and injury, whereas inhibition of autophagy by 3-methyladenine (3-MA) or Beclin-1 silencing exacerbated damage. These findings suggest that HPI induces autophagy, but the endogenous autophagic response is insufficient to counteract HPI-induced pathology; pharmacological enhancement of autophagy partially alleviated this insufficiency and reduced tissue damage. Notably, Beclin-1 knockdown blunted HPI-induced upregulation of PI3K and autophagy-related genes, suggesting a role for Beclin-1 in the transcriptional regulation of these responses. In conclusion, HPI simultaneously exerts direct pro-inflammatory effects and induces Beclin-1-dependent autophagy. Enhancing this autophagic response pharmacologically, rather than relying on the endogenous level triggered by HPI alone, limits excessive tissue damage. Thus, boosting autophagy may represent a promising therapeutic strategy against HPI-bearing pathogenic E. coli infections.\n\nID: 42586046\nTitle: Wiring autophagy: Neural circuits regulate lysosomal homeostasis in muscle.\nAbstract: Autophagy is commonly viewed as a cell-autonomous degradative process governed by intracellular metabolic and stress signals,1 but how autophagy is coordinated across tissues in multicellular organisms remains unclear. Zheng et al. 2 identify two parallel neuronal circuits that non-cell-autonomously regulate muscle autophagy in C. elegans, revealing an unexpected role for the nervous system in orchestrating peripheral autophagy.\n\nID: 42585801\nTitle: The decline of progranulin expression in cochlear Microglia-Like Cells accelerates the progression of age-related hearing loss.\nAbstract: Accumulating evidence indicates that crosstalk between immune cells and intrinsic cochlear cells is critical for maintaining auditory homeostasis. However, the activation profile of cochlear microglia-like cells (MLCs) and their mechanistic role in age-related hearing loss (ARHL) remain poorly defined. Here, we show that MLCs are robustly activated in the cochlea of aged mice, and that pharmacologic depletion of cochlear MLCs significantly attenuates ARHL progression. To dissect the mechanisms underlying MLC-driven cochlear damage in ARHL, we leveraged the single-cell transcriptomic landscape of the aged mouse cochlea previously generated by our research group, and conducted the related functional validation. We identified prominent age-related alterations in cochlear MLCs, and revealed that AAV-mediated (via posterior semicircular canal microinjection) upregulation of progranulin (GRN) in MLCs mitigates aging-associated oxidative stress damage in the cochlea. Collectively, our work demonstrates that targeting GRN signaling in cochlear MLCs alleviates aging-related oxidative stress in the cochlea, and thereby delays ARHL progression.\n\nID: 42580595\nTitle: The mechanism of SOX4/IGF2BP3/TRIB3 axis inhibiting autophagy and aggravating liver injury in sepsis.\nAbstract: Sepsis-associated liver injury (SALI) is a serious complication with limited treatment options. While protective autophagy is often suppressed in sepsis, the underlying mechanisms remain unclear. This study investigated whether the SOX4/IGF2BP3/TRIB3 pathway contributes to liver dysfunction by suppressing cytoprotective autophagy. In vitro experiments were performed using LPS-treated mouse primary hepatocytes, with measurements of SOX4, IGF2BP3, and TRIB3 expression by RT-qPCR and Western blot, cell viability by CCK-8, autophagic flux by mRFP-GFP-LC3 probe, and molecular interactions via luciferase reporter, ChIP, RIP, and RNA stability assays. In vivo, a murine sepsis model was established by cecal ligation and puncture. Clinically, mRNA levels of SOX4, IGF2BP3, and TRIB3 were measured in peripheral blood mononuclear cells from sepsis patients and correlated with clinical scores and outcomes. We found that the SOX4/IGF2BP3/TRIB3 axis was upregulated in septic hepatocytes, and its knockdown alleviated LPS-induced injury and impaired autophagic flux. SOX4 transcriptionally activated IGF2BP3, which stabilized TRIB3 mRNA in an m6A-dependent manner. Rescue experiments confirmed that this axis exacerbated LPS-induced hepatocyte injury by suppressing autophagic flux. Inhibition of SOX4 or IGF2BP3 alleviated liver injury and improved survival in septic mice. Clinically, circulating SOX4, IGF2BP3, and TRIB3 levels stratified the presence and severity of SALI and provided high-precision prognostic information. In conclusion, in SALI, SOX4 upregulates IGF2BP3, which stabilizes TRIB3 mRNA in an m6A-dependent manner. Accumulation of TRIB3 protein suppresses cytoprotective autophagy, ultimately leading to hepatocyte death and liver dysfunction.\n\nID: 42577954\nTitle: Protective effects of royal jelly on testicular tissue damage in rats treated with methotrexate: the relationship between oxidative stress and autophagy.\nAbstract: The present study evaluated the protective effects of royal jelly (RJ) on methotrexate (MTX)-induced testicular damage in rats, focusing on oxidative stress and autophagy. Methotrexate, a folic acid analogue used in cancer and autoimmune treatments, impairs spermatogenesis via oxidative stress and apoptosis. Twenty-four male Wistar rats were randomized into four groups: Control (normal saline, 35 days), MTX (0.30 mg kg-1, gavage, three times per week, 35 days), MTX + RJ (0.30 mg kg-1 MTX + 0.10 mg kg-1 RJ, gavage, three times per week, 35 days), and RJ (0.10 mg kg-1, gavage, three times per week, 35 days). After 35 days, rats were euthanized and testicular tissue was analyzed via histopathology, immunohistochemistry for LC3-I/II expression in germ cells and qRT-PCR for mRNA expression of autophagy-related genes (Beclin-1, Atg7, LC3-I). Histopathological findings revealed that MTX caused severe interstitial edema, coagulative necrosis and disrupted spermatogenesis with reduced seminiferous tubule diameter, epithelial thickness, tubular differentiation index (TDI) and spermiogenesis index. Co-administration of RJ significantly improved seminiferous tubule morphology, diameter, epithelial thickness, TDI and spermiogenesis index. Immunohistochemistry showed a significant increase in LC3-I/II+ germ cells (spermatogonia, spermatocytes, spermatids) in the MTX group which was markedly reduced in the MTX + RJ group. Similarly, qRT-PCR analysis demonstrated elevated mRNA levels of Beclin-1, Atg7, and LC3-I in the MTX group which were significantly reduced in the MTX + RJ group. These findings suggested that RJ mitigated MTX-induced testicular damage by reducing oxidative stress and autophagy, thereby, preserving spermatogenesis and testicular integrity.\n\nID: 42576802\nTitle: Mechanism of Autophagic Extracellular Vesicles Revealed.\nAbstract: Recent work by Mao and colleagues identifies a distinct class of small extracellular vesicles, termed autophagic extracellular vesicles (AEVs), generated from amphisomes upon autophagy induction. In this commentary, we discuss how this study provides important mechanistic insight into the coupling between autophagy and secretion. AEVs are molecularly and functionally distinct from canonical exosomes, being enriched in autophagy-related components such as LC3 and p62, and dependent on core ATG machinery for their biogenesis. Notably, their secretion is enhanced by autophagy induction and contributes to intercellular communication, particularly in the context of viral infection. These findings position amphisomes as critical sorting hubs that direct cargo toward either degradation or secretion, thereby integrating autophagic and endolysosomal pathways. We further highlight how these results intersect with prior evidence implicating SNARE-dependent mechanisms, including VAMP7 and stress-responsive regulators such as GRASP55, in unconventional secretion. Finally, we discuss key unresolved questions, particularly the mechanisms underlying the generation of small intraluminal vesicles within amphisomes and the role of ESCRT machinery in this process. Overall, the identification of AEVs adds a new layer of complexity to extracellular vesicle biology and opens new avenues for understanding how autophagy contributes to intercellular signaling in health and disease.\n\nID: 42573717\nTitle: Selenium Nanoparticles Alleviate Intestinal Epithelial Barrier Dysfunction by Coordinating Mitochondria-lysosome Communication under Dual Organelle Stress.\nAbstract: Intestinal barrier homeostasis is closely associated with coordinated signaling between mitochondria and lysosomes. Although our previous studies demonstrated the barrier-protective effects of biogenic selenium nanoparticles (SeNPs), the inter-organelle signaling mechanisms underlying this protection under dual-organelle stress remain unclear. In the present study, we established a targeted dual-injury model in IPEC-J2 cells using chloroquine (CQ) and 2,4-dinitrophenol (DNP) to investigate the signaling events governing mitochondria-lysosome communication. Combined exposure to CQ and DNP profoundly disrupted organelle homeostasis, as evidenced by severe adenosine triphosphate (ATP) depletion, elevated intracellular reactive oxygen species (ROS) and mitochondrial superoxide production, impaired lysosomal acidification, and altered autophagy-related processes. These synergistic insults ultimately promoted apoptosis, induced tight junction disassembly, and increased epithelial permeability. Notably, SeNPs pretreatment significantly upregulated the mRNA expression of key selenoproteins, including SELENOF, SELENOS, and SELENOP, and restored the activities of the selenium-dependent antioxidant enzymes glutathione peroxidase (GPx) and thioredoxin reductase (TrxR). This restoration of antioxidant capacity attenuated intracellular ROS and mitochondrial superoxide accumulation and restored the bioenergetic support required for autophagy-related processes and lysosomal acidification. Mechanistically, restoration of intracellular redox homeostasis by SeNPs prevented oxidative stress-induced dissociation of the TBC1D15/Rab7/Fis1 complex, a key tethering axis involved in mitochondria-lysosome communication. Stabilization of this complex was accompanied by improved autophagy-lysosome homeostasis and preservation of intestinal epithelial barrier integrity. Collectively, these findings demonstrate that biogenic SeNPs preserve intestinal epithelial barrier integrity under dual-organelle stress by enhancing selenoprotein-mediated antioxidant defense, thereby stabilizing mitochondria-lysosome tethering and restoring inter-organelle communication.\n\nID: 42568173\nTitle: CircHECTD1 Promotes Cholangiocarcinoma Progression Through Interaction With SFPQ to Induce Autophagy.\nAbstract: Cholangiocarcinoma (CCA) constitutes a highly malignant tumor type demonstrating rising global incidence rates. Circular RNAs (circRNAs), characterized by their covalently bonded single-stranded loop configuration, have been identified as functional regulators across various cancer types. Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression.\n\nID: 42564319\nTitle: Exosomal MicroRNAs as Emerging Liquid Biopsy Biomarkers in Glioma: Diagnostic, Prognostic, and Therapeutic Implications for Neuro-Oncology.\nAbstract: Glioblastoma remains the most aggressive malignant brain tumor, with limited survival despite advances in surgery, radiotherapy, and chemotherapy. Current diagnostic modalities are insufficient for early detection and precise monitoring of disease progression, prompting interest in liquid biopsy-based biomarkers. Exosomal microRNAs (miRNAs) have been highlighted as significant biomarkers due to their stability and involvement in tumor progression. This narrative review evaluates current evidence regarding the diagnostic, prognostic, and therapeutic significance of exosomal and extracellular vesicle-associated miRNAs in brain tumors, particularly gliomas. Data were collected from PubMed and Google Scholar, and eight original articles published between 2016 and 2026 were included after careful screening. The findings demonstrated dysregulated expression of exosomal miRNAs, including miR-29b, miR-210, miR-301a, miR-454-3p, and miR-2276-5p, which were significantly associated with tumor grade, recurrence, survival, and treatment response. The majority of studies reported strong diagnostic performance, with receiver operating characteristic/area under the curve values ranging from 0.80 to 0.93, while mechanistic analyses implicated these miRNAs in oncogenic pathways, including PTEN/AKT signaling, hypoxia-mediated progression, autophagy regulation, and angiogenesis. Overall, exosomal miRNAs demonstrate considerable potential as noninvasive biomarkers for prognostication and therapeutic targeting, while their dynamic preoperative alterations further suggest utility in disease monitoring.\n\nID: 42559728\nTitle: Nanoparticle-Mediated TIPE1 mRNA Delivery Enhances Paclitaxel Sensitivity in Triple-Negative Breast Cancer by Modulating RAB7A Ubiquitination-Associated Stability and Autophagy.\nAbstract: Acquired paclitaxel (PTX) resistance remains a major obstacle in triple-negative breast cancer (TNBC) treatment. This study investigated TIPE1's role in regulating autophagy and PTX sensitivity and developed ROS-responsive TIPE1 mRNA-loaded nanoparticles (TIPE1m NPs) as a therapeutic strategy. PTX-resistant TNBC cell lines were established, and integrated transcriptomic and proteomic analyses were performed. TIPE1 was downregulated in resistant cells, while higher TNFAIP8L1 expression in public breast cancer cohorts was associated with better survival and improved PTX response. Mechanistically, TIPE1 overexpression was associated with ubiquitination-related reduction in the stability of the small GTPase RAB7A, leading to impaired autophagic flux, increased ROS accumulation, and enhanced PTX-induced apoptosis. Conversely, TIPE1 knockdown stabilized RAB7A, enhanced autophagy, and increased PTX tolerance. ROS-responsive TIPE1m NPs were constructed to restore TIPE1 expression in resistant cells. TIPE1m NPs suppressed autophagy, increased ROS, and enhanced PTX-induced apoptosis in vitro. In PTX-resistant xenografts, combined TIPE1m NPs and PTX treatment suppressed tumor growth without obvious systemic toxicity. These findings identify the TIPE1-RAB7A-autophagy axis as a potential therapeutic target and support TIPE1 mRNA delivery as a strategy to overcome PTX resistance in TNBC.\n\nID: 42545381\nTitle: Circular RNAs orchestrate molecular networks in osteoarthritis: From miRNA sponging to epigenetic and exosome-mediated regulation.\nAbstract: Osteoarthritis (OA) is a progressive degenerative joint disorder characterized by cartilage breakdown, chronic inflammation, and impaired tissue homeostasis, representing a major global health burden with limited disease-modifying therapies. In recent years, circular RNAs (circRNAs), a class of covalently closed non-coding RNAs, have emerged as critical regulators of gene expression in OA pathogenesis. Due to their high stability, tissue specificity, and evolutionary conservation, circRNAs have attracted increasing attention as key molecular modulators of cartilage homeostasis and potential therapeutic targets. This review comprehensively summarizes current advances in the molecular mechanisms of circRNAs in OA, with a particular focus on their roles as competing endogenous RNAs (ceRNAs), epigenetic regulators, and mediators of intercellular communication via exosomes. Current evidence indicates that circRNAs participate in multiple pathological processes associated with OA, including extracellular matrix (ECM) degradation, chondrocyte apoptosis, autophagy dysfunction, inflammatory signaling, and mitochondrial stress, primarily through modulation of signaling pathways such as NF-\u03baB, PI3K/AKT, PTEN, and SIRT. Emerging evidence further highlights their involvement in epigenetic regulation via DNA methylation machinery and their participation in exosome-mediated intercellular communication within the joint microenvironment. Importantly, circRNAs exhibit dual functional roles, acting either as pathogenic amplifiers of cartilage degeneration or as protective regulators that promote chondrocyte survival and tissue repair. This functional versatility underscores their potential as both diagnostic biomarkers and therapeutic targets in OA. Moreover, advances in extracellular vesicle-based delivery systems and synthetic RNA engineering provide promising strategies for translating circRNA biology into clinical applications. Despite these advances, challenges remain regarding mechanistic complexity, tissue-specific functions, and efficient in vivo delivery systems. A deeper understanding of circRNA regulatory networks may facilitate the development of next-generation RNA-based precision therapies for osteoarthritis.\n\nID: 42539973\nTitle: CNOT11 depletion is associated with autophagy-related responses and IL-6-JAK-STAT signaling in cancer cells.\nAbstract: The CCR4-NOT complex is a central regulator of deadenylation-mediated mRNA decay, yet the role of its vertebrate-specific subunit CNOT11 remains unclear. We investigated the role of CNOT11 in cellular stress responses using siRNA-mediated knockdown, immunoblotting, immunoprecipitation, transcriptomic analysis, quantitative RT-PCR, ELISA, cycloheximide chase assays, actinomycin D treatment, and poly(A) tail analysis. CNOT11 depletion did not markedly alter the expression of other CCR4-NOT subunits but reduced the association of CNOT10 with the complex. CNOT11 knockdown was associated with LC3-II accumulation, transcriptional upregulation of autophagy-related genes, and changes in AMPK/ULK1 signaling. Increased IL-6 expression and secretion and enhanced STAT1 and STAT3 phosphorylation were also observed. IL-6 knockdown or STAT3 inhibition partially attenuated LC3-II accumulation. Increased IL-6 expression was associated with elevated transcription, without detectable changes in mRNA stability or poly(A) tail length. These findings suggest that CNOT11 depletion is associated with LC3-II accumulation and other autophagy-related responses, with IL-6-JAK-STAT signaling contributing partially to this phenotype. Definitive assessment of autophagic flux and the causal positioning of IL-6 signaling will require further studies using gold-standard flux assays and IL-6 rescue or neutralization approaches.\n\nID: 42539297\nTitle: Targeted modulation of IGFBP5/IGF1, THPO, and P38 MAPK signaling are potent therapeutic strategies generalizable for mitochondrial respiratory chain disease and osteosarcoma.\nAbstract: Primary mitochondrial diseases (PMD) have limited disease-modifying therapies, currently applicable to only 3 of over 400 discrete gene disorders. Cycloheximide (CHX) is a global cytosolic translation inhibitor we previously reported to rescue PMD preclinical models, although its toxicity precluded clinical development. To identify specific mediators underlying CHX treatment benefit in PMD, SOMAscan-based proteomics was performed in complex I deficient and genetic disease fibroblast cell line models grown in galactose. Thrombopoietin (THPO) and insulin-like growth factor binding protein 5 (IGFBP5) were the only two differentially regulated proteins, together with ERK/MAPK pathway dysregulation, identified upon CHX treatment in PMD versus healthy control cells. THPO inhibition by siRNA or pharmacologic approaches rescued stress-induced viability loss in patient fibroblasts having diverse PMD gene etiologies, and significantly improved mitochondrial stress, linear growth, and neuromuscular function in a classical ndufs2 -/- C. elegans model. IGFBP5 overexpression by lentiviral or mRNA approaches rescued cell viability across distinct PMD gene etiologies, as did IGF1 pharmacologic inhibition across both PMD mutant and C. elegans models. MAPK pharmacologic inhibition rescued multiple distinct complex I disease cells' survival, as well as mitochondrial stress in SLC25A46 -/- C. elegans . Combination therapies targeting multiple of these glucose signaling pathway proteins, together with glucose and N-acetylcysteine, yielded superior therapeutic benefit in complex I disease cell and C. elegans models. Additionally, single or combined pharmacologic inhibition of THPO or IGF1 significantly enhanced primary and metastatic osteosarcoma cell death. Collectively, targeted small molecule and genetic modulation of THPO, IGF1, or MAPK recapitulated the significant therapeutic benefit of CHX in PMD, while avoiding global translation inhibition. These novel PMD therapies likely confer benefit by attenuating MAPK-driven autophagy and potentially promoting noncanonical glucose uptake, improving cellular energy balance. Overall, these glucose signaling cellular pathway targets hold broad therapeutic promise for PMD patients, warranting further clinical research development.\n\nID: 42539135\nTitle: Progranulin haploinsufficiency remodels the cerebral microvasculature and neurovascular unit.\nAbstract: Progranulin (PGRN) deficiency is a major genetic cause of frontotemporal dementia (FTD), yet its impact on cerebrovascular function remains understudied. Here, we show that PGRN deficiency contributes to cerebral microvascular perfusion and induces alterations within the neurovascular unit. In vivo two-photon imaging revealed increased capillary stalling and reductions in cerebral blood flow (CBF), driven in part by increased leucocyte-capillary interactions and elevated endothelial ICAM-1 expression. Transcriptomic profiling of isolated cerebral microvessels demonstrated coordinated upregulation of immune and extracellular matrix pathways alongside suppression of angiogenic and stress-response programs, indicative of endothelial activation. Cross-species analyses identified partial conservation of these vascular signatures in endothelial cells from human FTD-GRN patients, associated with dysregulated angiogenic and inflammatory signaling. Despite altered tight junction organization and reduced solute carrier transporter expression, blood-brain barrier (BBB) permeability remained largely intact, suggesting functional rather than structural BBB disruption, as well as. These vascular changes were accompanied by broad alterations in the morphology of astrocytes, pericytes, and microglial cells. Here we determined a novel role for progranulin in cerebrovascular homeostasis and established microvascular dysfunction as a key driver of FTD-GRN pathophysiology.\n\nID: 42537606\nTitle: Solid-state NMR methods to investigate biomolecular condensates, protein phase transition, phase separation and coacervates.\nAbstract: The formation of biomolecular condensates has been linked to a broad range of essential cellular processes, including immune signaling cascades, mRNA transport, and autophagy. Conversely, phase-separated condensates have also been associated with aberrant protein misfolding and subsequent aggregation in neurodegenerative disease-related processes. Protein phase separation and phase transitions involve the formation of heterogeneous and dynamic assemblies that can evolve into gel-like or semi-crystalline states, which are challenging to characterize using high-resolution structural biology techniques. Solid-state nuclear magnetic resonance (NMR) spectroscopy now offers a broad arsenal of methods to probe the structural and dynamic features of viscous condensates, elastic solids, coacervates and rigid protein assemblies. This review provides an overview of solid-state NMR approaches that are readily applicable and discusses potential methodological developments to investigate protein condensates and coacervates as well as to study protein phase separation and phase transitions.\n\nID: 42536443\nTitle: Liver sinusoidal endothelium mediates systemic clearance of ultrasmall gold nanoparticles through secretion of circulating exosomes.\nAbstract: Liver sinusoidal endothelium featuring a unique discontinuous lining and robust endocytic activity is vital for nanoparticle retention, clearance, and translocation. However, liver sinusoidal endothelium-mediated nanoparticle elimination remains far less understood than liver macrophage uptake despite both processes being involved in hepatic detoxification. Using water-soluble Au25(o-MBA)18 (o-MBA: o-mercaptobenzoic acids) with optimized local hydrophobicity for weak protein-binding affinity and high endothelium targeting as probes, we report an exosome-mediated systemic clearance for endocytosed nanoclusters in sinusoidal endothelial cells. Au25(o-MBA)18 can effectively avoid phagocytosis by liver macrophage, are initially endocytosed by sinusoidal endothelial cells through clathrin-dependent endocytosis, processed through endosomal pathways, and released as exosomes containing nanoclusters into the bloodstream. During the exosome biogenesis, Au25(o-MBA)18 progressively transform into flower-like aggregates (approximately 100 nm). These circulating exosomes traverse the glomerular membrane through autophagy in glomerular endothelial cells and podocytes before urinary excretion. Here, this exosome-mediated pathway converts exogenous ultrasmall gold nanoparticles into biocompatible endogenous exosome-enveloped cargos for systemic circulation with reduced toxicity, providing a foundation for developing next generation of safe and effective nanomedicines.\n\nID: 42533576\nTitle: Molecular mechanisms of the hypothalamus miR-27a/ PRKCA pathway in regulating neuronal function and aggression-related behavior.\nAbstract: The intensification of livestock production has heightened public concern about animal welfare, with aggressive behavior recognized as a key determinant of both welfare and productivity. MicroRNAs (miRNAs), which are critical post-transcriptional regulators, have emerged as important modulators of animal behavior. This study investigated the molecular basis of aggression in pigs ( Sus scrofa), focusing on miRNA-mediated regulation. Hypothalamic miRNA-sequencing of the most aggressive ( n=4) and least aggressive ( n=4) piglets identified nine differentially expressed miRNAs. Among these, miR-27a was significantly upregulated in aggressive individuals. Functional assays demonstrated that both porcine miR-27a and its human ( Homo sapiens) ortholog has-miR-27a-3p, suppressed autophagy, apoptosis, and neuronal plasticity in primary porcine neurons and human SH-SY5Y neuroblastoma cells. To clarify the underlying mechanisms, mRNA-sequencing was performed on porcine neurons transfected with miR-27a mimics or negative controls, identifying 436 differentially expressed genes (84 upregulated and 352 downregulated). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses highlighted eight genes- CBL, PRKCA, SLC38A1, ZBTB16, AANAT, CYP1A1, SLC7A11, and NTRK2-associated with tryptophan metabolism, oxidative stress, and long-term synaptic depression. Bioinformatic analysis and dual-luciferase reporter assays confirmed that miR-27a directly targets the 3'-UTR of PRKCA, thereby suppressing of autophagy, apoptosis, and neuronal plasticity. In vivo, intrahypothalamic injection of mmu-miR-27a-3p in mice ( Mus musculus) reduced motor function and social dominance, and placed the mice at a competitive disadvantage, while supressing neuronal autophagy, apoptosis and plasticity. \u968f\u7740\u96c6\u7ea6\u5316\u52a8\u7269\u751f\u4ea7\u7684\u666e\u53ca\uff0c\u4eba\u4eec\u5bf9\u52a8\u7269\u798f\u5229\u7684\u5173\u6ce8\u65e5\u76ca\u589e\u52a0\u3002\u653b\u51fb\u884c\u4e3a\u4f5c\u4e3a\u5f71\u54cd\u52a8\u7269\u798f\u5229\u7684\u91cd\u8981\u56e0\u7d20\uff0c\u5bf9\u63d0\u5347\u798f\u5229\u6c34\u5e73\u548c\u751f\u4ea7\u6548\u7387\u81f3\u5173\u91cd\u8981\u3002\u800c\u4f5c\u4e3a\u8f6c\u5f55\u540e\u8c03\u63a7\u7684\u5173\u952e\u5206\u5b50miRNA\u5df2\u6210\u4e3a\u52a8\u7269\u884c\u4e3a\u7684\u91cd\u8981\u8c03\u8282\u56e0\u5b50\u3002\u8be5\u7814\u7a76\u65e8\u5728\u4ece\u5206\u5b50\u5c42\u9762\u89e3\u6790\u732a\u653b\u51fb\u884c\u4e3a\u7684\u5f62\u6210\u673a\u5236\uff0c\u91cd\u70b9\u5173\u6ce8 miRNA \u4ecb\u5bfc\u7684\u8c03\u63a7\u4f5c\u7528\u3002\u901a\u8fc7\u5bf9\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\uff08 n = 4\uff09\u548c\u8f83\u5f31\uff08 n = 4\uff09\u4ed4\u732a\u4e0b\u4e18\u8111\u8fdb\u884c miRNA \u6d4b\u5e8f\uff0c\u5171\u9274\u5b9a\u51fa 9 \u79cd\u5dee\u5f02\u8868\u8fbe\u7684 miRNA\u3002\u5176\u4e2d\uff0cmiR-27a \u5728\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\u7684\u4e2a\u4f53\u4e2d\u663e\u8457\u4e0a\u8c03\u3002\u7ec6\u80de\u529f\u80fd\u5b66\u9a8c\u8bc1\u8868\u660e\uff0cssc-miR-27a \u53ca\u5176hsa-miR-27a-3p \u80fd\u591f\u6291\u5236\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u548c\u4eba\u795e\u7ecf\u6bcd\u7ec6\u80de\u7624\u7ec6\u80de\u7cfb\uff08SH-SY5Y\uff09 \u7684\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002\u4e3a\u4e86\u8fdb\u4e00\u6b65\u63a2\u7a76 miR-27a \u5bf9\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u7684\u8c03\u63a7\u4f5c\u7528\uff0c\u901a\u8fc7\u5bf9\u8f6c\u67d3 miR-27a \u6a21\u62df\u7269\u548c\u9634\u6027\u5bf9\u7167\u7684\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u8fdb\u884c mRNA-seq\uff0c\u5171\u9274\u5b9a\u51fa 436 \u4e2a\u5dee\u5f02\u8868\u8fbe\u57fa\u56e0\uff0884 \u4e2a\u4e0a\u8c03\uff0c352 \u4e2a\u4e0b\u8c03\uff09\u3002\u5bcc\u96c6\u5206\u6790\uff08GO\u3001KEGG\u3001PPI\uff09\u53d1\u73b0\u67098\u4e2a\u57fa\u56e0\u2014\u2014 CBL\u3001 PRKCA\u3001 SLC38A1\u3001 ZBTB16\u3001 AANAT\u3001 CYP1A1\u3001 SLC7A11 \u548c NTRK2\uff0c\u4e0e\u8272\u6c28\u9178\u4ee3\u8c22\u3001\u6c27\u5316\u5e94\u6fc0\u548c\u957f\u671f\u7a81\u89e6\u6291\u5236\u7b49\u901a\u8def\u76f8\u5173\u3002\u751f\u7269\u4fe1\u606f\u5b66\u548c\u53cc\u8367\u5149\u7d20\u9176\u62a5\u544a\u57fa\u56e0\u68c0\u6d4b\u8868\u660e\uff0cmiR-27a \u76f4\u63a5\u9776\u5411 PRKCA \u7684 3'-UTR\uff0c\u4ecb\u5bfc\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u7684\u6291\u5236\u3002\u6d3b\u4f53\u5b9e\u9a8c\u8868\u660e\uff0c\u5c0f\u9f20\u4e0b\u4e18\u8111\u5185\u6ce8\u5c04 mmu-miR-27a-3p \u4f1a\u964d\u4f4e\u5176\u8fd0\u52a8\u529f\u80fd\uff0c\u524a\u5f31\u5176\u793e\u4f1a\u652f\u914d\u5730\u4f4d\uff0c\u5e76\u4f7f\u5176\u5904\u4e8e\u7ade\u4e89\u52a3\u52bf\uff0c\u540c\u65f6\u6291\u5236\u5c0f\u9f20\u795e\u7ecf\u5143\u7684\u81ea\u566c\u3001\u7ec6\u80de\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002.\n\nID: 42533566\nTitle: An improved SMS p.Gly56Ser mouse model of Snyder-Robinson syndrome reveals phenotypic parallels with clinical features.\nAbstract: Snyder-Robinson syndrome (SRS), a rare X-linked disorder caused by pathogenic variants in spermine synthase (SMS), results in spermine deficiency and excessive spermidine accumulation. Previously reported mouse models exhibited reduced birthrate and survival of affected males, greatly limiting their experimental utility. Here we describe a new mouse model carrying the clinically relevant Sms p.Gly56Ser (SmsG56S) allele in which viable males are recovered at Mendelian ratios, enabling generation of adequately powered cohorts. Hemizygous males produce markedly reduced SMS protein across tissues, recreating the biochemical hallmark of SRS, an elevated spermidine:spermine ratio. SmsG56S/Y males exhibit reduced body size, altered body composition, decreased locomotor and exploratory behaviors, and reduced seizure threshold, aligning with clinical features reported in SRS patients. Serum LDL, HDL, and cholesterol levels were reduced, while brain histology revealed modest region-specific astrocytic changes. Comprehensive polyamine profiling revealed tissue-specific biochemical disturbances, highlighting putrescine elevation in the brain and informing development of translational strategies and windows for intervention. Overall, this improved model reproduces multiple key aspects of the human SRS phenotype and provides a robust platform for mechanistic studies and preclinical evaluation of therapies.\n\nID: 42533037\nTitle: Hippocampal neuronal progranulin mediates estrogen\u2011deficiency\u2011induced affective vulnerability and lysosomal-autophagic dysfunction.\nAbstract: Perimenopausal women typically face a heightened risk of emotional disturbances, including anxiety and depression. The estrogen decline increases vulnerability to mood disorders, but the molecular mechanisms underlying stress resilience remain unclear. Here, we identify hippocampal neuronal progranulin (PGRN), a secreted neuroprotective glycoprotein, as a key regulator of affective resilience under estrogen-deficient conditions. Ovariectomy (OVX) reduces hippocampal neuronal PGRN expression and induces anxiety- and depression-like behaviors, whereas estradiol supplementation restores both PGRN levels and behavior. Adeno-associated virus (AAV)-mediated overexpression of PGRN alleviates affective deficits across OVX, 4\u2011vinylcyclohexene diepoxide (4-VCD)-induced ovarian failure, and natural aging models, while neuronal, but not microglial, Grn deletion exacerbates stress susceptibility. Mechanistically, PGRN restores lysosomal protease activity, normalizes autophagic flux, activates AMP-activated protein kinase (AMPK) phosphorylation, and rescues mushroom spine loss, thereby restoring cellular and synaptic homeostasis. Intracerebral recombinant PGRN rescues OVX\u2011induced behavioral deficits, and the blood-brain barrier (BBB)-permeable fragment granulin-E (GRN\u2011E) confers similar protection after systemic administration. Collectively, these findings demonstrate that hippocampal neuronal PGRN links estrogen signaling to lysosomal-autophagy pathways and synaptic plasticity, and highlight PGRN or its active fragments as promising therapeutic targets for perimenopausal depression and anxiety.\n\nID: 42531677\nTitle: GATA4 modulates autophagy, apoptosis and tight junction marker remodeling in Bactrian camel Sertoli cells.\nAbstract: Bactrian camels exhibit distinct seasonal estrus, with periodic testicular functional fluctuations regulating their reproductive activity. As a key transcription factor in reproductive modulation, the specific role of GATA4 in the testicular microenvironment of Bactrian camels remains unclear. This study investigates the expression patterns of GATA4 in the testicular tissue during estrus and anestrus phases, alongside its potential regulatory effects on Sertoli cells (SCs) function. Utilizing mRNA sequencing, we analyzed testicular samples in estrus (n\u202f=\u202f3) and anestrus (n\u202f=\u202f3), identifying 291 differentially expressed genes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed that GATA4 was involved in reproduction-related processes, including tight junction formation, autophagy, and cell cycle regulation. Notably, validation showed that GATA4 expression was significantly upregulated in testicular tissue during the anestrus period, with its protein localized primarily in SCs. Gain- and loss-of-function assays revealed that altered GATA4 expression is associated with changes in autophagy-related marker profiles, evidenced by a lower LC3II/LC3I ratio, decreased Beclin-1, and increased P62 expression level. Silencing GATA4 induced opposite alterations in these autophagy-associated molecular markers, and these molecular changes are associated with modified mTOR/NF-\u03baB pathway expression. Additionally, GATA4 influences SCs apoptosis and G0/G1 cell cycle arrest and these cellular phenotypic changes are accompanied by alterations in the PI3K/AKT pathway, which correlates with changed levels of BAX, Caspase-3, BCL2, and CDK1. And moreover, GATA4 modulates the expression of the tight junction markers ZO-1 and Occludin, and these remodeling events are associated with modified WNT1/\u03b2-catenin signaling. In conclusion, GATA4 exhibits dynamic expression patterns throughout the reproductive cycle, which correlates with the modulation of multiple biological processes in SCs, including autophagy-related marker remodeling, apoptosis regulation, and tight junction marker remodeling. This study's findings provide a key molecular target for elucidating the seasonal reproductive mechanism and reproductive regulation of Bactrian camels and enrich the current understanding of reproductive regulatory mechanisms in this species.\n\nID: 42523917\nTitle: Neuroprotective potential of selenium nanoparticles and/or physical and mental activities against social isolation-induced depression in a rat model: inflammatory, oxidative stress, apoptotic, and neurotransmission modulatory pathways.\nAbstract: Social isolation (SI), attributable to modern lifestyles and fast-growing technology, is a leading cause of depression. Selenium nanoparticles (Se-NPs) are neuroactive agents owing to their antioxidant and anti-inflammatory activities. Additionally, physical and mental activities (Ph&M) exert neuroprotective effects by optimizing the release of both neurotransmitters and growth factors. However, their neuroprotective effects against SI-induced depression are still poorly investigated. We aim to explore the neuroprotective effect of Se-NPs, Ph&M, and their combination to guard against the harmful effects of SI-induced depression in a rat model. Fifty Sprague Dawley rats were randomly allocated into five groups: control, SI, Ph&M, orally administered Se-NPs (0.1\u00a0mg/kg), and a combination group. Neuroprotective activity was quantitatively estimated pharmacologically, biochemically, histologically, and behaviorally. SI caused behavioral and biochemical alteration in the rat model, decreasing neurotransmitter levels, increasing the transcription of inflammatory response genes (TLR4 and NF-\u03baB), and consequently increasing the production of the cytokines TNF-\u03b1 and IL-1\u03b2. It also activated the proinflammatory NLRP3/caspase-1 pathway. The ER stress parameters PERK, CHOP, and GRP78 were significantly elevated. Impairment of autophagy and increased neurodegeneration were detected via the decline of AMPK/SIRT-1/Beclin-1 PI3K/AKT gene expression and m-TOR overexpression. Decreased expression of TrkB and CREB mRNA and consequent decline in brain-derived neurotropic factor were recorded. SI caused a drastic drop in Wnt3a and \u03b2-catenin levels and increased GSK3\u03b2 activity affecting neuroplasticity and cognitive functions. Administration of Se-NPs and/or application of Ph&M, especially their combination, provided significant protection against prior SI effects. Se-NPs and Ph&M, especially their combination, showed promising protective effects against neuroinflammation, oxidative stress, apoptosis and subsequent alterations of test animal behaviors precipitated by SI.\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: 42520681\nTitle: PNPT1-induced mitochondrial dysfunction drives osteoclast activation via post-transcriptional Nrf2 suppression and lipid peroxidation signaling.\nAbstract: Polynucleotide phosphorylase 1 (PNPT1) functions as a crucial mitochondrial enzyme; nevertheless, its potential genetic correlation with osteoporosis and its specific regulatory impact on osteoclastogenesis remain to be elucidated. We executed a two-sample Mendelian randomization (MR) strategy to interrogate the causal link connecting PNPT1 expression to osteoporosis risk. For in vivo substantiation, we utilized both an ovariectomized (OVX) murine model and an adeno-associated virus (AAV)-driven overexpression system. Extensive in vitro assays employing RANKL-stimulated RAW264.7 macrophages were conducted to evaluate osteoclast differentiation, mitochondrial dynamics, autophagic flux, and intracellular oxidative stress through molecular and morphological analyses. MR evaluations pinpointed genetically predicted elevated PNPT1 expression as a potential genetic risk factor for osteoporosis. In vivo observations revealed a significant surge of PNPT1 within the osteoclast precursors of OVX subjects. In vitro, the ectopic overexpression of PNPT1 significantly enhanced osteoclastogenesis and bone degradation while simultaneously triggering severe mitochondrial depolarization alongside the accumulation of reactive oxygen species (ROS). On the contrary, targeted Pnpt1 silencing markedly suppressed osteoclast maturation. Mechanistic probes demonstrated that PNPT1 disrupted autophagic flux, marked by p62 accumulation. Notably, even with a compensatory transcriptional rise in Nrf2 mRNA, PNPT1 overexpression provoked a marked downregulation of Nrf2 and xCT proteins, suggesting a potent post-transcriptional suppression of the cellular antioxidant shield. This uncoupling invariably precipitated sub-lethal lipid peroxidation that amplifies osteoclastogenic signaling. Concordantly, AAV-mediated systemic PNPT1 amplification aggravated trabecular bone deterioration in vivo. Guided by our MR findings and validated through our functional models, PNPT1 emerges as a potential genetic risk factor for osteoporosis. By inciting mitochondrial damage, provoking ROS buildup, and decoupling the protective autophagy-Nrf2/xCT axis, PNPT1 promotes osteoclastogenesis, thereby introducing a promising immunopharmacological target for restraining pathological bone resorption.\n\nID: 42519007\nTitle: Multi-omics profiling reveals gut microbiome signatures associated with cognitive decline in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is increasingly being linked to gut microbial dysbiosis via the gut-brain axis. We applied integrated metagenomics and metabolomics to characterize gut microecology in 28 patients with AD and 33 controls. Metagenomic analysis revealed distinct microbial community structures, with increased abundance of Akkermansia massiliensis, Alistipes onderdonkii, and Barnesiella intestinihominis in AD. Phageome analysis revealed increased richness and altered composition, with more Podoviridae and fewer Microviridae. Functional profiling identified shifts in microbial metabolic pathways involving tryptophan and short-chain fatty acid metabolism. Untargeted metabolomics revealed elevated fecal spermidine, taurocholate, and glycerophosphocholine levels in patients with AD. A random forest model combining metabolites, gut metabolic modules, and bacteriophages achieved good within-cohort classification (AUC = 0.83) but lacked external validation due to unavailable matched fecal metabolomic data. Overall, these findings link AD to coordinated disruptions across bacterial, viral, and metabolic gut layers, highlighting the need for external validation and mechanistic studies.\n\nID: 42511454\nTitle: Adipose-Derived Mesenchymal Stem Cell Exosomes Attenuate Oxygen-Glucose Deprivation-Induced Cochlear Damage by Inducing Autophagy-Associated Signaling.\nAbstract: Ischemia plays a critical role in the pathogenesis of sensorineural hearing loss through the induction of severe cochlear apoptosis and mitochondrial dysfunction. Exosomes derived from adipose-derived mesenchymal stem cells (ADMSC-Exo) have robust protective effects under non-otologic ischemic conditions. However, their otoprotective effects remain unclear. This study aimed to investigate the protective effects of human ADMSC-Exo against cochlear damage and mitochondrial dysfunction under oxygen-glucose deprivation (OGD), an in vitro and ex vivo model of cochlear ischemia. ADMSC-Exo attenuated OGD-induced cytotoxicity and apoptosis in HEI-OC1 cells and reduced the OGD-induced loss of cochlear hair cells in the organ of Corti explants. OGD caused a decrease in mitochondrial mass and mitochondrial membrane potential depolarization and impaired mitochondrial respiration in auditory cells. ADMSC-Exo preserved mitochondrial integrity and improved mitochondrial bioenergetic function following OGD exposure. These effects were accompanied by increased LC3-II conversion and formation of autolysosome-like structures and elevated expression of PINK1 and Parkin, indicating the activation of autophagy and mitophagy-related protective mechanisms. Importantly, 3-methyladenine, an autophagy inhibitor, attenuated the cytoprotective effect of ADMSC-Exo, supporting the involvement of autophagy in ADMSC-Exo-mediated protection. Collectively, these findings suggest that ADMSC-Exo protect against OGD-induced cochlear injury by promoting autophagy-associated mitochondrial protection.\n\nID: 42511092\nTitle: Role of Autophagy in Goose Astrovirus-Induced Renal Injury in Goslings.\nAbstract: Goose astrovirus (GoAstV) is a newly identified virus affecting geese, leading to goose gout, which is marked by urate deposits in organs and joints. This research investigates the role of autophagy in renal damage caused by GoAstV in goslings. The findings indicated that GoAstV infection in goslings resulted in characteristic clinical manifestations, with renal tissues displaying tubular swelling, inflammatory infiltration, and autophagosome formation. In vivo experiments demonstrated a significant upregulation of mRNA levels for autophagy-related factors, including AMPK, LC3A, ATG5, ATG7, P62, Beclin1, AMBRA1 and GABARAPL1, while mTOR and LC3B levels were notably decreased. At 3 dpi, the protein expression levels of ATG5, Beclin1, and LC3B II/I increased, while P62 levels decreased, suggesting autophagy activation. In vitro analyses revealed that GoAstV infection led to enhanced autophagy; however, the concurrent upregulation of LC3B II/I and P62 proteins suggested an obstruction in the autophagic flux. Upon the inhibition of autophagy with 3-methyladenine (3-MA, autophagy inhibitor), there was a significant reduction in the expression of autophagy-related factors, accompanied by a marked decrease in viral replication rates. In conclusion, GoAstV infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux. The virus exploits autophagosomes for replication, ultimately resulting in kidney damage. The application of 3-MA effectively inhibits this autophagic process and diminishes viral replication.\n\nID: 42510853\nTitle: Multilayer Genomic Characterization of a Shared Genetic Factor Linking Depression-Related Liability and Reduced Physical Function.\nAbstract: Background: Depression-related liability is frequently accompanied by reduced physical function, yet the shared genetic architecture linking mood-related traits and physical-function decline remains incompletely characterized. Methods: We applied genomic structural equation modeling to European-ancestry GWAS summary statistics for five constituent phenotypes: depressive symptoms, depression diagnosis, grip strength, appendicular lean mass, and walking pace. A Depression-Physical Function shared genetic factor was constructed as a cross-trait genetic covariance dimension and evaluated using LDSC-based validation and leave-one-trait-out sensitivity analyses. We then performed factor GWAS, FUMA locus annotation, Bayesian fine-mapping, MAGMA gene-based analysis, transcriptome-wide association analysis, pathway enrichment, CELLECT/MAGMA cell-type specificity analysis, partitioned heritability analysis, and gsMap spatial transcriptomic mapping. Results: The shared factor showed good model fit and retained 755,397 quality-controlled variants for downstream analysis. The factor was positively genetically correlated with depression-related traits and negatively correlated with physical-function-related traits. FUMA identified 245 genome-wide significant SNPs, 44 lead SNPs, and 38 genomic risk loci, with 127 positional mapped genes. Fine-mapping prioritized one high-confidence locus. MAGMA identified 19 Bonferroni-significant genes and 326 FDR-significant genes, while TWAS identified 322 FDR-significant expression-associated genes. Integrating FUMA positional mapping, MAGMA gene-level association and TWAS expression-level association prioritized eight convergent genes: TMEM106B, CENPW, DRD2, LRFN5, NCAPG, DCAF16, SGIP1, and FAM120A. Functional enrichment highlighted postsynaptic structure, neuron spine, synaptic plasticity, and synapse organization. CELLECT/MAGMA prioritized brain non-myeloid neurons and glial populations, with additional endocrine-metabolic and immune-hematopoietic signals. Spatial transcriptomic mapping localized top signals to brain and spinal cord regions in the embryonic neuro-muscle reference. Partitioned heritability analysis showed enrichment in conserved, intronic, promoter, and chromatin-related genomic annotations. Conclusions: These findings support a shared polygenic covariance dimension linking depression-related liability with reduced physical-function-related genetic propensity. Downstream analyses prioritized candidate loci, genes, and biological contexts, with enrichment patterns consistent with neuronal, synaptic, and regulatory genomic processes.\n\nID: 42510787\nTitle: Identification and Preliminary Clinical Assessment of Key Genes Related to Endoplasmic Reticulum Stress and Autophagy in Minimal Change Disease.\nAbstract: Background: Minimal change disease (MCD) is a leading cause of childhood nephrotic syndrome. Endoplasmic reticulum stress (ERS) and autophagy are implicated in its pathogenesis, but the precise mechanisms remain unclear. This study aimed to identify ERS and autophagy-related key genes (ERS-RGs and ARGs) in MCD using bioinformatic and experimental approaches. Methods: Transcriptomic data from GSE216841 and GSE246206 were analyzed. ERS-RGs and ARGs were obtained from prior literature. Candidate genes were selected by integrating weighted gene coexpression network analysis and differential expression analysis. Feature genes were identified via protein-protein interaction network analysis and machine learning (Least Absolute Shrinkage and Selection Operator and Boruta). Key genes were validated by expression analysis and receiver operating characteristic evaluation. A multilayer perceptron (MLP) model was constructed, and regulatory networks, immune infiltration, and chemical compound prediction were analyzed. The expression levels of the identified key genes were preliminarily assessed in peripheral blood samples using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Results:LIG4 and ZRANB3 were identified as key genes, both significantly downregulated in the MCD group, and the gene-based MLP model effectively predicted MCD probability. Overall, 13 significantly different immune cell types (e.g., CD56+ natural killer and activated dendritic cells) were detected. Regulatory networks (transcription factor-messenger RNA (mRNA) and long non-coding RNA-microRNA-mRNA) and 8 common chemical compounds (e.g., bisphenol A, acetaminophen) targeting these genes were predicted. Notably, peripheral blood RT-qPCR analysis revealed significant LIG4 and ZRANB3 downregulation, suggesting a systemic expression signature. Conclusions:LIG4 and ZRANB3 are key genes associated with ERS and autophagy in MCD, providing insights for diagnosis and targeted therapy.\n\nID: 42507332\nTitle: Disease mechanisms and translational barriers guide nanocarrier design for nose to brain delivery in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder with limited disease-modifying treatment options, partly because many therapeutic agents show insufficient brain exposure and dose-limiting systemic adverse effects after conventional administration. Nose-to-brain (N2B) delivery has emerged as a non-invasive strategy to transport therapeutics to the central nervous system through the olfactory and trigeminal pathways, thereby partially bypassing the blood-brain barrier. Recent advances in nanomedicine and biomaterial engineering have further improved this approach by enhancing drug stability, nasal residence, mucosal transport, and brain-targeting efficiency. This review examines nanocarrier-enabled N2B delivery strategies for AD from a mechanism-guided perspective, highlighting how AD-related pathological processes shape the selection of therapeutic cargos and formulation designs. We discuss recent progress in the intranasal delivery of repurposed small molecules, natural products, insulin-related agents, peptides and proteins, extracellular vesicles, antibodies, and nucleic acid-based therapeutics. We further summarize major nanocarrier and formulation platforms, including lipid-based systems, polymeric nanoparticles, micelles, extracellular vesicles, in situ gels, and device-assisted delivery technologies. Particular attention is given to the design parameters that influence N2B performance, including particle size distribution/PDI, surface charge, mucus interaction, cargo protection, targeting modification, biodistribution, and deposition reproducibility. Finally, we critically evaluate the translational challenges that continue to limit clinical application, including species differences in nasal anatomy, dose-volume restrictions, device-dependent variability, limited human pharmacokinetic evidence, manufacturing complexity, long-term safety, and regulatory requirements. By integrating disease mechanisms, nanocarrier design, and translational considerations, this review provides a structured perspective for developing more rational and clinically feasible N2B nanodelivery systems for AD.\n\nID: 42503062\nTitle: Integrated miRNA-mRNA-degradome analysis unveils the key regulatory mechanism of ginseng under temperature-water stress.\nAbstract: MYB and bHLH are the key transcription factors to coordinate the balance between antioxidant system and secondary metabolism under combined temperature-water stress. Low temperature and drought severely impede medicinal plant growth and secondary metabolite accumulation. Identifying key regulatory genes or modules and clarifying their molecular mechanisms is critical for advancing the ginseng industry. Using ginseng hairy roots, we established a composite stress system combining 5\u00a0\u00b0C with 10-30% polyethylene glycol. We assessed effects on ginseng hairy roots growth, ginsenoside content, and stress-related physiological responses, and performed miRNA, transcriptome, and degradome sequencing analysis. Low-temperature and mild-drought (LTD) treatment significantly promoted ginsenoside accumulation, peaking on day 8, and enhanced antioxidant enzyme activity, indicating robust stress tolerance. Co-analysis identified four miRNAs, mtr-MIR159a-p3_2ss16GT17CT_1, mtr-MIR159a-p3_2ss16GT17CT_2, ptc-miR319a_L\u2009+\u20091R-1, and stu-miR482c_2ss12AT18GA that target MYB and bHLH transcription factor family and exhibit negative expression correlations. These miRNAs likely act as central regulators of ginsenoside biosynthesis under combined temperature-water stress, providing mechanistic insights into how ecological factors modulate ginsenoside production.\n\nID: 42492605\nTitle: Exosomes from bone marrow mesenchymal stem cells inhibit osteoclast differentiation and alleviate osteoporosis via RBM15B/YAP1 to induce autophagy.\nAbstract: Osteoporosis develops primarily as a result of an imbalance between osteoclastic bone resorption and osteoblastic bone formation. Bone marrow mesenchymal stem cells-derived-exosomes (BMSCs-Exos) regulate osteoclast differentiation and osteoporosis in recent studies. But the mechanisms are still unclear. This research aimed to explore the mechanisms of BMSCs-Exos in osteoclast differentiation and osteoporosis. Exosomes were extracted from BMSCs. THP-1\u202fcells were cultured and treated with BMSCs-Exos. Osteoclast- and autophagy-related gene expression was assessed by qPCR and Western blot, the regulation of YAP1 by RBM15B was analyzed by MeRIP and RNA pull-down, osteoclast differentiation was detected by TRAP staining. HE staining, immunohistochemical staining and micro-CT were employed to assess the impact of BMSCs-Exos on osteoporosis. BMSCs-Exos were internalized by THP-1\u202fcells, promoted YAP1 expression and autophagy, and inhibited osteoclast differentiation. Silencing of YAP1 in THP-1\u202fcells reversed BMSCs-Exos-induced autophagy and the inhibition of osteoclast differentiation; conversely, YAP1 overexpression produced opposite effects. BMSCs-Exos-delivered RBM15B promoted m6A methylation modification of YAP1. Silencing of RBM15B in BMSCs blocked the impact of BMSCs-Exos on autophagy and osteoclast differentiation, whereas RBM15B overexpression exerted opposing influences. Furthermore, BMSCs-Exos suppressed osteoclast differentiation and alleviated osteoporosis in vivo through RBM15B/YAP1 mediated autophagy. BMSCs-Exos promoted m6A methylation modification of YAP1 by delivering RBM15B mRNA to enhance YAP1 RNA stability, promoted autophagy, and inhibited osteoclast differentiation and alleviated osteoporosis.\n\nID: 42492603\nTitle: Neonatal propofol exposure induces region-specific neurotoxic proteomic signatures in mouse cortex and hippocampus.\nAbstract: Neonatal propofol exposure has been implicated in long-term neurodevelopmental impairments; however, region-specific molecular mechanisms remain unclear. This study examined region-specific proteomic alterations in exosome-enriched small extracellular vesicles (exosome-enriched sEVs) from the cortex and hippocampus induced by neonatal propofol exposure. Using a clinically relevant repeated-dose regimen, C57BL/6 mice received propofol (50\u00a0\u00a0mg/kg, P5-P7). At P21, exosome-enriched sEVs were isolated and analyzed by data-independent acquisition mass spectrometry. Candidate differentially expressed proteins (candidate DEPs) were defined by fold change (FC)\u00a0\u2265\u00a01.5 or\u00a0\u2264\u00a00.667 and nominal p\u00a0<\u00a00.05, followed by Gene Ontology (GO), KEGG pathways, Cluster of Orthologous Groups (COG), and domain enrichment analyses. After Benjamini-Hochberg correction, no protein reached q\u00a0<\u00a00.05, indicating that the exploratory findings were not significant. We identified 63 candidate DEPs in the hippocampus and 55 in the cortex. Hippocampal downregulated proteins enriched in synaptic vesicle cycling, oxidative phosphorylation, and apoptosis, suggesting synaptic-mitochondrial disruption; upregulated proteins associated with ER stress and chaperone-mediated autophagy, suggesting proteostatic adaptation. Cortical candidate DEPs reflected suppressed mitochondrial function alongside enhanced translation and cytoskeletal remodeling. These region- and direction-specific changes were consistently observed across all bioinformatic platforms. The hippocampus showed pronounced synaptic and mitochondrial alterations, while the cortex exhibited cytoskeletal changes and metabolic shifts. In conclusion, Propofol induces distinct neurotoxic proteomic signatures in the neonatal hippocampus and cortex, suggesting compartment-specific vulnerability and compensatory remodeling. Thus, exosome-enriched sEV proteomics offers a sensitive approach to detecting early anesthetic-induced neurodevelopmental disturbances.\n\nID: 42491593\nTitle: The role of endoplasmic reticulum stress-mediated autophagy in cadmium-induced liver injury in rats.\nAbstract: Cadmium (Cd) is a widespread toxicant with high bioaccumulation potential. This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage.\n\nID: 42488829\nTitle: Challenges and opportunities for ginseng-based medicines in treating cardiac fibrosis from mechanistic insights to clinical translation.\nAbstract: Cardiac fibrosis, characterized by excessive extracellular matrix (ECM) deposition and progressive myocardial remodeling, is a common pathological outcome of various cardiovascular diseases and lacks effective targeted anti-fibrotic therapies. Panax ginseng and its related preparations, including major ginsenosides (e.g., Rb1, Rg1, and Rg3), standardized extracts, and compound formulas, have garnered growing interest owing to their multi-component, multi-target pharmacological activities and integrative regulatory effects. This review systematically summarizes recent advances in the basic and clinical research of ginseng-based medicines in the prevention and treatment of cardiac fibrosis. Preclinical evidence demonstrates that ginseng and its active constituents attenuate key pathological processes, including oxidative stress, inflammatory responses, apoptosis, and autophagy dysregulation, primarily through modulation of signaling pathways such as TGF-\u03b2/Smad, NF-\u03baB, and PI3K/Akt. These regulatory effects collectively contribute to the inhibition of fibroblast activation, reduction of collagen deposition, and improvement of myocardial structure and function. Emerging clinical studies further suggested potential benefits in improving cardiac function and modulating fibrosis-related biomarkers in patients with hypertension, coronary heart disease, and heart failure (HF). Despite these promising findings, several challenges hinder clinical translation, including low oral bioavailability, the mechanistic complexity of compound formulas, and insufficient high-quality clinical evidence. Future investigations should integrate novel drug delivery strategies, systems pharmacology approaches to elucidate holistic mechanisms, and well-designed randomized controlled trials to facilitate the development of ginseng-based medicines as potential therapeutic agents for cardiac fibrosis.\n\nID: 42486831\nTitle: [Natural bear bile powder attenuates lipopolysaccharide-induced acute lung injury in mice by regulating the NF-\u03baB and Nrf-2/HO-1 signaling pathways].\nAbstract: To investigate the mechanism that mediates the protective effect of bear bile powder (BBP) against lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. Cultured RAW264.7 cells were pretreated with, different concentrations of BBP, or dexamethasone (Dex) for 1 h before LPS challenge. Sixty male C57BL/6 mice were randomized into 5 groups (n=12), including a control group, a LPS-induced ALI model group, a Dex treatment group, and two BBP treatment groups treated with low- (30 mg/kg) or high-dose (120 mg/kg) BBP. The levels of inflammatory factors and oxidative stress-related indicators in the cells and mouse lung tissues were determined, and mouse lung histopathology, wet/dry weight ratio, and BALF cell count were examined; the expressions of NF-\u03baB and Nrf-2/HO-1 pathways were detected using qPCR, Western blotting, and immunohistochemistry. In LPS-stimulated RAW264.7 cells, BBP (12.5 \u03bcg/mL) significantly reduced the levels of TNF-\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, NO and ROS, enhanced SOD activity, increased mRNA expressions of I\u03baB-\u03b1, Nrf-2, and HO-1, and lowered mRNA expressions of TNF-\u03b1, IL-1\u03b2, Keap-1, and NF-\u03baB (p65). The ALI mouse models showed severe lung pathologies and edema, increased BALF cell counts, and increased levels of TNF\u2011\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, and NO, lowered SOD activity with reduced protein expressions of I\u03baB-\u03b1, Nrf-2, and HO-1 and increased expressions of Keap-1 and p65. Treatment with high-dose BBP significantly ameliorated lung pathologies in the mouse models and improved the aberrant alterations in pulmonary expressions of inflammatory factors, oxidative stress-related indicators and the NF-\u03baB and Nrf-2/HO-1 pathways. BBP protects against LPS-induced ALI in mice possibly by targeting the Nrf-2/HO-1 and NF-\u03baB pathways, suggesting its potential as a therapeutic agent for ALI. \u76ee\u7684: \u63a2\u7a76\u718a\u80c6\u7c89\uff08BBP\uff09\u901a\u8fc7\u8c03\u63a7NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u5bf9\u8102\u591a\u7cd6\u8bf1\u5bfc\u7684\u6025\u6027\u80ba\u635f\u4f24\uff08ALI\uff09\u5c0f\u9f20\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u4f53\u5916\u5b9e\u9a8c:\u91c7\u7528\u8102\u591a\u7cd6\uff08LPS\uff09\u8bf1\u5bfcRAW264.7\u7ec6\u80de\u5efa\u7acb\u4f53\u5916\u6a21\u578b\uff0c\u8bbe\u7f6e\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001\u5730\u585e\u7c73\u677e\uff08Dex\uff0c25 \u03bcg/mL\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff086.25 \u03bcg/mL\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff0812.5 \u03bcg/mL\uff09\u3002\u4f53\u5185\u5b9e\u9a8c:\u5c0660\u53eaC57BL/6\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001Dex\u7ec4\uff085 mg/kg\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff0830 mg/kg\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff08120 mg/kg\uff09\uff0c12\u53ea/\u7ec4\u3002\u901a\u8fc7ELISA\u548c\u76f8\u5173\u8bd5\u5242\u76d2\u68c0\u6d4b\u7ec6\u80de\u548c\u80ba\u7ec4\u7ec7\u4e2d\u708e\u75c7\u4e0e\u6c27\u5316\u5e94\u6fc0\u6307\u6807;\u901a\u8fc7\u80ba\u7ec4\u7ec7\u75c5\u7406\u5206\u6790\u3001\u514d\u75ab\u7ec6\u80de\u8ba1\u6570\u548c\u80ba\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u7b49\u6307\u6807\u8bc4\u4ef7BBP\u5bf9ALI\u7684\u5e72\u9884\u4f5c\u7528\u3002\u901a\u8fc7qRT-PCR\u3001Western blotting\u548c\u514d\u75ab\u7ec4\u5316\u6cd5\u5206\u6790NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u76f8\u5173\u86cb\u767d\u4e0e\u57fa\u56e0\u7684\u8868\u8fbe\u53d8\u5316\u3002\u7ed3\u679c: \u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\u7ec4\uff0812.5\u03bcg/mL\uff09\u663e\u8457\u964d\u4f4eTNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u4e00\u6c27\u5316\u6c2e\uff08NO\uff09\u548c\u6d3b\u6027\u6c27\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff0c\u4e14I\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff0c\u800cTNF-\u03b1\u3001IL-1\u03b2\u3001Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff08P<0.05\uff0cP<0.01\uff0cP<0.001\uff09\u3002\u52a8\u7269\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u7ed3\u6784\u7d0a\u4e71\uff0c\u80ba\u6ce1\u58c1\u589e\u539a\uff0c\u80ba\u6ce1\u5185\u53ef\u89c1\u5927\u91cf\u708e\u75c7\u7ec6\u80de\u6d78\u6da6\uff0c\u80ba\u7ec4\u7ec7\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u53ca\u652f\u6c14\u7ba1\u80ba\u6ce1\u704c\u6d17\u6db2\uff08BALF\uff09\u603b\u7ec6\u80de\u6570\u5347\u9ad8\uff08P<0.01\uff09;\u80ba\u7ec4\u7ec7\u4e2d\u7684TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u542b\u91cf\u5347\u9ad8\uff0c\u800cSOD\u6d53\u5ea6\u964d\u4f4e\uff08P<0.01\uff0cP<0.001\uff09;\u4e14\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff0cKeap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\uff08120 mg/kg\uff09\u7ec4\u80fd\u6539\u5584\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u75c5\u7406\u635f\u4f24\u72b6\u6001\uff0c\u6539\u5584\u80ba\u80bf\u80c0\u7a0b\u5ea6\uff0c\u964d\u4f4eBALF\u603b\u7ec6\u80de\u6570\u3001TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09;\u540c\u65f6\uff0cBBP\u4e0a\u8c03\u4e86\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u5e76\u6291\u5236\u4e86Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09\u3002\u7ed3\u8bba: BBP\u53ef\u80fd\u901a\u8fc7\u4f5c\u7528\u4e8eNrf-2/HO-1\u548cNF-\u03baB\u4fe1\u53f7\u901a\u8def\u5bf9LPS\u8bf1\u5bfc\u7684ALI\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u540e\u7eed\u7814\u7a76\u6f5c\u5728\u7684\u6cbb\u7597ALI\u836f\u7269\u63d0\u4f9b\u4f9d\u636e\u3002.\n\nID: 42486454\nTitle: Yishen Tongluo formula regulates apoptosis and autophagy in testicular spermatogenic cells of oligoasthenozoospermic rats via the AMPK/mTOR pathway.\nAbstract: Yishen Tongluo Formula (YSTLF) is a modern compound formula derived from the traditional Chinese medicine (TCM) theory of \"kidney deficiency and collateral obstruction\", and consists of seven Chinese medicinal herbs. It has been used clinically to treat oligoasthenozoospermia (OAS) for more than two decades, with proven efficacy and a favorable safety profile. However, its precise molecular mechanism has yet to be fully elucidated. The aim was to investigate the therapeutic efficacy and the underlying mechanism of YSTLF in treating OAS associated with the kidney deficiency and collateral obstruction pattern. The chemical constituents of YSTLF were identified by UHPLC-Q-Orbitrap HRMS, and molecular docking was performed between the ten most abundant compounds and AMPK/mTOR. Rat OAS models were established by combined GTW, adrenaline, and ice-water immersion. Pharmacodynamic effects were evaluated through general status, reproductive organ weights, sperm quality, coagulation parameters, and serum sex hormones. Testicular histopathology, ultrastructure, and autolysosomes were examined by HE staining and TEM. Apoptosis was detected by TUNEL staining, and autophagy/apoptosis-related protein expression by IHC. Integrated metabolomics and proteomics with KEGG enrichment were conducted. In GTW-injured GC-1spg cells treated with Compound C or rapamycin, CCK-8 assay assessed viability, flow cytometry evaluated apoptosis, immunofluorescence examined LC3B/cleaved caspase-3 expression and colocalization, and Western blotting/RT-qPCR validated AMPK/mTOR pathway key molecules. Among 307 identified compounds (mostly flavonoids), YSTLF improved general status, organ weights, and sperm quality in model rats. The ten most abundant compounds showed binding energies < -7.0\u202fkcal/mol for AMPK/mTOR. Sperm concentration and motility increased dose-dependently. PT and TT were prolonged, FIB decreased, and FSH, LH, T, PRL, and Inh-B were restored. H&E, TEM, and TUNEL revealed alleviated testicular pathology, improved ultrastructure, reduced autolysosomes, and decreased apoptosis. IHC showed downregulated Beclin1 and Bax, and upregulated p62 and Bcl-2. Multi-omics revealed co-enrichment of differential proteins/metabolites in autophagy and mTOR pathways. Western blot/RT-qPCR validated downregulated p-AMPK/AMPK, AMPK mRNA, LC3II, Beclin1, Bax, cleaved caspase-3, and cleaved caspase-3/caspase-3 ratio, alongside upregulated p-mTOR/mTOR, mTOR mRNA, p62, and Bcl-2. In vitro, GTW reduced viability concentration-/time-dependently (stable model: 10%/24\u202fh); YSTLF reversed this (optimal: 15%/24\u202fh), restored viability, reduced apoptosis, and decreased LC3B/cleaved caspase-3 fluorescence/colocalization, while downregulating p-AMPK, LC3II, Bax and upregulating p-mTOR, p62, Bcl-2. Compound C alone mimicked YSTLF's effects without additivity, whereas rapamycin aggravated GTW-induced viability loss, apoptosis, and autophagy/apoptosis co-activation. YSTLF improved spermatogenic function in rats with OAS (kidney deficiency and collateral obstruction pattern). Its mechanism of action involves regulation of the AMPK/mTOR signaling pathway and restoration of the balance between autophagy and apoptosis.\n\nID: 42486133\nTitle: High-dose chemotherapy followed by autologous stem-cell transplantation versus non-myeloablative consolidation in primary CNS lymphoma (MATRix/IELSG43): a randomised phase 3 trial.\nAbstract: Consolidation therapy for primary CNS lymphoma (PCNSL) includes high-dose chemotherapy with autologous stem-cell transplantation (HCT-ASCT), yet its efficacy compared with non-myeloablative chemoimmunotherapy remains uncertain. This study aimed to provide randomised comparative evidence on the efficacy and safety of thiotepa-based HCT-ASCT versus non-myeloablative R-DeVIC consolidation after uniform MATRix induction in newly diagnosed PCNSL. This open-label, randomised, phase 3 trial was conducted across 56 university and academic non-university hospitals with established transplantation facilities in five European countries. Eligible for inclusion were untreated, immunocompetent patients with B-cell PCNSL, aged 18-65 years regardless of Eastern Cooperative Oncology Group (ECOG) performance status, or 66-70 years with ECOG performance status 0-2. Pretreatment corticosteroids were permitted. Exclusion criteria included lymphoma manifestation outside the CNS, and congenital or acquired immunodeficiency. Patients received four cycles of MATRix induction (comprising rituximab, high-dose cytarabine, and thiotepa, in addition to high-dose methotrexate). Patients reaching at least partial response were randomly assigned (1:1) to two cycles of R-DeVIC (rituximab plus dexamethasone, etoposide, ifosfamide, and carboplatin) or HCT-ASCT with carmustine and thiotepa. The primary endpoint was progression-free survival, assessed in the full analysis set (excluding patients with major violations of entry criteria). The safety analysis set contained all randomised patients who initiated therapy. This study is registered with ClinicalTrials.gov (NCT02531841) and the EU Clinical Trials Register (EudraCT number 2012-000620-17). The study is completed. Between July 16, 2014, and Aug 31, 2019, 368 patients were enrolled. 346 (94%) patients started induction treatment, and 230 were randomly assigned; 229 patients were analysed (R-DeVIC group, n=115; HCT-ASCT group, n=114). After a median follow-up of 45\u00b73 months, 3-year progression-free survival was significantly superior in the HCT-ASCT group (hazard ratio 0\u00b743 [95% CI 0\u00b727-0\u00b768]; p=0\u00b70003). The 3-year progression-free survival was 78% (95% CI 69-85) in the HCT-ASCT group compared with 51% (41-60) in the R-DeVIC group. The mean number of adverse events per patient was 9\u00b73 (SD 4\u00b74) in the R-DeVIC group and 14\u00b76 (5\u00b78) in the HCT-ASCT group. Fatal serious adverse events following consolidation treatment occurred in two patients in the R-DeVIC group (both acute myeloid leukaemia) and in five patients in the HCT-ASCT group (infections and infestations [n=4], pulmonary embolism [n=1]); all of these events apart from the pulmonary embolism were judged to be possibly related to treatment. In the largest randomised trial in untreated PCNSL to date, HCT-ASCT significantly improved progression-free and overall survival compared with non-myeloablative consolidation in patients who had completed induction treatment, establishing it as the preferred consolidation strategy in fit patients.

In this study, we analyzed 3825 global human cellular phosphoproteome studies, identifying 430 qualitative profiles and 55 quantitative differential datasets featuring high-confidence Class-1 phosphosites (localization probability \u2265 75%; A-score \u2265 13). Notably, S136 and S138 emerged as predominant phosphorylation sites outside the kinase domain. These sites showed frequent detection and differential expression in liver, lung, and head and neck cancers, as documented in PhosphositePlus. We identified a high-confidence set of co-regulated phosphoproteins, including SQSTM1, SRRT, RPS6, TP53BP1, TNKS1BP1, THUMPD1, OTUD4, and TCEA1. These proteins link CLK4 to critical pathways, including RNA splicing, autophagy, DNA damage response, and cancer progression. Binary interactors, including SRRM2, Interacts with SPT6 1 (IWS1), RBBP6, ZC3H18, BUD13, and DYRK1A, further connect CLK4 to RNA processing and splicing. Predicted downstream substrates, such as CCNL2, CDK11B, PRDX6, YTHDC1, RBM15, SRRM1, SFSWAP, HNRNPU, and DOCK7, highlight CLK4's broad regulatory scope. Upstream kinases were also predicted for S136 and S138. Site-resolved analyses revealed tumor-specific dysregulation of CLK4 phosphorylation at key residues. Co-occurring phosphosite alterations and nearby somatic mutations suggest disrupted CLK4 regulation in cancer. Overall, this study provides a comprehensive phosphoproteomic resource that maps CLK4's co-regulatory networks, paving the way for mechanistic investigations and targeted cancer therapies.\n\nID: 42482577\nTitle: [Mechanism of acupuncture at \"Houxi\"(SI3) and \"Huantiao\"(GB30) in influencing autophagy of nucleus pulposus cells by regulating PI3K/AKT/mTOR signaling pathway in rats with lumbar intervertebral disc degeneration].\nAbstract: To observe the effect of acupuncture at the acupoint pair \"Houxi\"(SI3) and \"Huantiao\"(GB30) on the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway and autophagy of nucleus pulposus cells in a rat model of intervertebral disc degeneration (IDD), so as to explore its underlying mechanism in delaying IDD. A total of 36 male SD rats were randomly assigned to sham operation, model and acupoint pair groups, with 12 rats in each group. The IDD model was established by annulus fibrosus puncture. After modeling, rats of the acupoint pair group received acupuncture stimulation of bilateral SI3 and GB30, with the acupuncture needles retained for 20 min, once daily for 14 consecutive days. Before and after modeling and after the intervention, the mechanical withdrawal reflex threshold (mechanic pain threshold) of the right foot was measured using VonFrey filaments, and the thermal pain threshold measured by using a thermal pain tester. The morphological characteristics of the intervertebral disc tissue were observed by H.E. staining. The contents of type \u2161 collagen (Collagen \u2161), Aggrecan, matrix metalloproteinase 3 (MMP3), matrix metalloproteinase 13 (MMP13), and transcription factor sex-determining region Y-box protein 9 (SOX9) in the nucleus pulposus tissue were detected by ELISA. The mRNA relative expression levels of SOX9 and MMP13 in the nucleus pulposus tissue were detected by real-time fluorescence quantitative PCR. The positive expression of microtubule-associated protein 1 light chain 3 (LC3) in the nucleus pulposus tissue was detected by immunofluorescence staining. The expression levels of PI3K/AKT/mTOR signaling pathway-related proteins and LC3- \u2161, Beclin1, and chaperone 1 (p62) in the nucleus pulposus tissue were detected by Western blot. After modeling, in contrast to the sham operation group, the model group showed a striking decrease in the mechanical and thermal pain thresholds on day 7 and 14, contents of Aggrecan, collagen \u2161 and SOX9, and the expression levels of SOX9 mRNA and p62 protein, ratios of p-PI3K/PI3K, p-AKT/AKT, and p-mTOR/mTOR in the nucleus pulposus tissue (P<0.001, P<0.01), and a notable increase in the contents of MMP3 and MMP13, and MMP13 mRNA expression level, LC3 immunofluorescence intensity, and protein expressions of LC3-\u2161 and Beclin 1 (P<0.001). Under light microscope, the nucleus pulposus cells in the model group was relatively small in the number and discorded in the distribution, with a large number of vacuoles and chaotic matrix arrangement, and the lumbar intervertebral discs showed obvious degeneration, and decrease in the height. In comparison with the model group, both the decrease and increase of the indexes mentioned above were all reversed in the acupoint pair group (P<0.001, P<0.01, P<0.05). The results of H.E. stain displayed that in the acupoint pair group, the arrangement of the nucleus pulposus cells was more regular, and the number of vacuoles was reduced. Acupuncture of acupoint pair SI3 and GB30 can mitigate pain and regulate the autophagy process of lumbar intervertebral disc nucleus cells, reduce the degree of degradation of cytoplasmic matrix, and thereby delay the progression of IDD, which may be associated with its function in activating PI3K/AKT/mTOR signaling pathway in IDD rats. \u76ee\u7684:

42481898\nTitle: Adipose-Derived Mesenchymal Stem Cells and Their Exosomes Ameliorate Sperm-related Abnormalities, Hormonal Imbalance, and Disrupted Testicular Autophagy in A Diet-Induced Murine Model for Non-Alcoholic Fatty Liver Disease.\nAbstract: Non-alcoholic fatty liver disease (NAFLD), a common metabolic disorder, is increasingly linked to impaired male reproductive health. This study investigates the therapeutic potential of adipose-derived mesenchymal stem cells (AD-MSCs) and their exosomes (AD-MSCs-Exo) in ameliorating NAFLD-induced testicular dysfunction in a murine model. Male C57BL/6 mice were divided into four groups: [n\u2009=\u20098 per group: control, high-fat diet (HFD), HFD\u2009+\u2009AD-MSCs, and HFD\u2009+\u2009AD-MSCs-Exo]. Sperm parameters according to the WHO Laboratory Manual, hormonal profiles via ELISA, and expression of genes involved in autophagy and spermatogenesis were assessed using qRT-PCR. HFD-induced NAFLD significantly reduced sperm count (P\u2009=\u20090.036), motility (P\u2009<\u20090.0001), viability (P\u2009=\u20090.023), and normal morphology (P\u2009=\u20090.015) while increasing DNA fragmentation (P\u2009=\u20090.004). Moreover, in the HFD group, LH and total testosterone levels decreased significantly (P\u2009=\u20090.0002 and P\u2009<\u20090.0001), whereas estradiol levels increased significantly (P\u2009=\u20090.0001) compared with controls. Expression of STAR was significantly downregulated (P\u2009=\u20090.0001); conversely, the relative fold changes of BECN1 (P\u2009=\u20090.0003), MAP-LC3b-a (P\u2009=\u20090.0002), and SQSTM-1/p62 (P\u2009=\u20090.005) were significantly enhanced in the HFD group compared to the controls. Treatment with AD-MSCs or AD-MSCs-Exo improved sperm quantity and quality and balanced hormonal levels. AD-MSCs showed slightly greater modulation of key autophagy genes (BECN1, MAP-LC3b-a, and SQSTM1/p62), whereas exosomes were more effective in hormonal restoration (especially testosterone) and in enhancing genes related to steroidogenesis (especially INHBB). AD-MSCs and their exosomes improve sperm-related abnormalities, hormonal imbalance, and testicular autophagy dysregulation in the NAFLD model. These findings support their potential as therapeutic agents for NAFLD-induced male infertility, highlighting translational relevance while noting the need for further clinical validation.\n\nID: 42480904\nTitle: Niclosamide ethanolamine induces malignant phyllodes tumor cell death via mTOR-TFEB axis-mediated lysosomal biogenesis and functional uncoupling.\nAbstract: Breast malignant phyllodes tumor (MPT) is a fibroepithelial neoplasm characterized by high recurrence rates. Currently, no effective therapeutic agents are available, and surgery remains the mainstay of treatment for MPT. Niclosamide ethanolamine (NEN), an antiparasitic agent, has recently demonstrated broad-spectrum antitumor activity against various solid malignancies. This study aimed to evaluate the antitumor efficacy of NEN against MPT and elucidate the underlying molecular mechanisms. The effects of NEN on MPT cell proliferation and migration were assessed using CCK-8, wound healing, and Transwell migration assays. Ultrastructural alterations following NEN treatment were examined by transmission electron microscopy. Bioinformatics analyses, quantitative real-time PCR (qPCR), Western blotting, and immunofluorescence staining were employed to investigate the molecular mechanisms underlying NEN-mediated modulation of autophagy and lysosomal function. NEN significantly inhibited MPT cell proliferation and migration. Transmission electron microscopy revealed the accumulation of numerous autolysosomal structures in NEN-treated cells. Mechanistically, NEN suppressed mTOR phosphorylation, promoted nuclear translocation of transcription factor EB (TFEB), and induced lysosomal biogenesis. However, lysosomal function was compromised, as evidenced by elevated luminal pH, impaired cathepsin D maturation, and lysosomal membrane permeabilization, ultimately resulting in autophagic flux blockade at the degradation stage. Furthermore, lysosomal cathepsin leakage activated the mitochondrial apoptotic pathway, culminating in caspase-3-dependent apoptosis. NEN effectively kills MPT cells by inducing \"lysosomal biogenesis-function uncoupling.\" This study is the first to reveal a novel anti-MPT mechanism that targets the mTOR-TFEB-lysosome axis and disrupts lysosomal homeostasis, providing a potential drug candidate for the treatment of MPT.\n\nID: 42480145\nTitle: Panasenoside promotes angiogenesis and mitigates vascular endothelial cell senescence via SIRT1 activation.\nAbstract: Angiogenesis is a crucial process in ischemia diseases like coronary heart disease, stroke and wound healing. Panasenoside (PSS) is a flavonoid glycoside ioslated from Chinese Materia Medica GINSENG RADIX ET RHIZOMA which has been demonstrated with multiple biological activities. However, the pharmacological activity of PSS and the underlying mechanism are still unclear. We found that PSS promoted sub-intestinal vessel plexus (SIVs) growth in zebrafish. PSS ameliorated vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor II (VRI)-induced deficiency of intersegmental vessels (ISVs) in a concentration dependent manner by downregulation of mRNA expression of VEGF receptors, including Kdr/VEGFR-2 (kdr), VEGFR-1 (flt1), and Kdr-like/VEGFR-2 (kdrl), and up-regulation of VEGF (vegfaa). The angiogenesis effect of PSS on VRI-induced ISVs deficiency was suppressed by PI3K, AKT, MEK, ERK, P38, Sirtuin 1 (SIRT1), Nuclear factor erythroid-2-related factor 2 (NRF2) and Nicotinamide N-methyl transferase (NNMT) inhibitors. Activation of NRF2, SIRT1 and MNA significantly restored VRI-induced ISVs insufficiency. In addition, PSS protected against VRI-induced tube formation deficiency in human umbilical vascular endothelial cells (HUVECs). SIRT1, NRF2 and NNMT inhibitors or siRNA eliminated PSS promoting vascular endothelial cell tube formation. PSS also prevented SIRT1, NRF2 and NNMT inhibitors-induced vascular endothelial cell senescence. Furthermore, PSS upregulated the protein expression level of SIRT1 and downregulated its downstreams P53 and PGC-1\u03b1 in HUVECs with high potence of activating SIRT1 by binding with its active domine. In conclusion, PSS presented pro-angiogenesis effect by mitigating vascular endothelial cell ageing and the underlying mechanisms were involved in the PI3K/AKT/MAPKs, SIRT1/NRF2 and NNMT/MNA signaling pathway with SIRT1 acting as a key regulator. We identified the pro-angiogenesis and anti-vascular endothelial cell ageing effects of PSS for the first time, and PSS is a promising drug candidate for treating vascular deficiency associated diseases.\n\nID: 42478918\nTitle: Glucosamine Promotes Autophagy and Attenuates Hepatic Steatosis Via O-GlcNAcylation-Mediated Mechanisms.\nAbstract: Autophagy is a key cellular process regulating lipid turnover and maintaining hepatic homeostasis, and its impairment is closely associated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD). In this study, we examined the effects of glucosamine (GlcN), a hexosamine biosynthetic pathway intermediate, on autophagy and lipid accumulation using both human hepatocellular carcinoma (HepG2) cells and a high-fat diet (HFD)-induced NAFLD mouse model. GlcN treatment led to a dose- and time-dependent increase in the expression of autophagy-related markers LC3 and p62 at both mRNA and protein levels. Pharmacological inhibition of O-GlcNAcase (OGA) further enhanced autophagic activity, whereas inhibition of O-GlcNAc transferase (OGT) abrogated GlcN-induced autophagic responses, implicating O-GlcNAcylation as a key mediator of GlcN-driven autophagy induction. Functionally, GlcN significantly reduced palmitic acid (PA)-induced lipid accumulation in HepG2 cells and alleviated hepatic steatosis in HFD-fed mice, likely through enhancement of autophagic flux. These findings demonstrate that GlcN promotes lipid clearance in hepatocytes via O-GlcNAc-dependent autophagy and highlight its potential as a therapeutic agent for NAFLD and related metabolic disorders.\n\nID: 42593127\nTitle: Progress on rotator cuff tendon-to-bone interface tissue regeneration and repair.\nAbstract: Tendon-bone interface (TBI) injuries, typified by rotator cuff tears, are common musculoskeletal disorders. Their intrinsic healing capacity is limited by pathological conditions such as local hypoxia, oxidative stress, and secondary fatty infiltration, which prevent spontaneous restoration of the native four-zone gradient architecture. As a result, functional tissue is often replaced by fibrovascular scar tissue with inferior mechanical properties. Because surgical repair alone cannot precisely recreate this complex interface, highly biomimetic tissue-engineered regenerative strategies have emerged as a promising alternative. Beginning with the anatomy of the rotator cuff and the key challenges in treating rotator cuff injuries, this review summarizes the spatiotemporal complexity, physiological vulnerability, and rehabilitation challenges of the TBI. It further discusses the structural composition, fabrication methods, mechanisms of action, and clinical applications of tissue-engineered strategies for TBI regeneration. These approaches use scaffolds based on hydrogels, decellularized matrices, polymers, collagen, and nanoparticles, which can be functionally engineered through graded architectures, aligned structures, mineralization cues, and tailored interfacial properties. In parallel, active components such as stem cells, exosomes, and bioactive factors can be incorporated to recreate a three-dimensional microenvironment that supports tissue regeneration, attenuates inflammation, regulates bone metabolic homeostasis, and promotes vascular regeneration. Although substantial progress has been made in tissue-engineered repair of rotator cuff injuries, future studies should place greater emphasis on digitally enabled and coordinated scaffold design, more robust safety assessment, and quantitative evaluation of therapeutic efficacy. Mechanistic studies and translational research will also be essential to bridge the gap between basic research and clinical application.\n\nID: 42591088\nTitle: Chlorogenic acid inhibits intestinal lipid uptake and promotes adipose lipid catabolism via epithelium-derived exosomes in ob/ob mice.\nAbstract: Chlorogenic acid has been widely reported to regulate lipid metabolism and alleviate obesity; however, its effects on intestinal lipid uptake and adipose tissue catabolism, as well as the underlying mechanisms, remain incompletely understood. In the present study, diabetic ob/ob mice were treated with chlorogenic acid, which significantly improved metabolic parameters, including body weight, serum triglyceride levels, glucose tolerance, and insulin sensitivity. Notably, chlorogenic acid reduced intestinal lipid content and downregulated the expression of genes involved in lipid transportation. Concurrently, epididymal adipose tissue weight was decreased, accompanied by enhanced expression of genes associated with lipid catabolism. Mechanistically, chlorogenic acid decreased triglyceride level and suppressed PPAR\u03b3 protein expression in IPEC-J2 cells. Activation of PPAR\u03b3 attenuated the inhibitory effects of chlorogenic acid on lipid accumulation, indicating a critical role of PPAR\u03b3 signaling. In addition, chlorogenic acid altered the concentration of epithelial cell-derived exosomes. These exosomes reduced triglyceride levels and modulated the expression of lipid metabolism-related genes in 3T3-L1 cells. Collectively, our findings suggest that chlorogenic acid may exert metabolic benefits, at least in part, through a coordinated intestine-adipose axis and provide preliminary evidence supporting a potential role for exosome-mediated inter-organ communication in the regulation of lipid homeostasis.\n\nID: 42589633\nTitle: Exosomes as Emerging Therapeutic and Diagnostic Platforms: Biological Functions, Clinical Applications, and Translational Challenges.\nAbstract: Exosomes are small membrane-bound extracellular vesicles of endosomal origin that play pivotal roles in intercellular communication by transferring proteins, lipids, metabolites, and nucleic acids. Increasing evidence indicates that these vesicles participate in diverse physiological and pathological processes, including immune regulation, tissue repair, tumor progression, neurodegeneration, and cardiovascular homeostasis. Their distinctive biological properties have consequently generated considerable interest in their development as diagnostic tools, therapeutic agents, and drug-delivery platforms. Recent progress in exosome biology and biogenesis, together with technological advances in vesicle isolation, characterization, engineering, and large-scale production, has accelerated their preclinical development and early clinical translation. Nevertheless, substantial challenges-including donor-cell heterogeneity, low production yields, insufficiently standardized protocols, and regulatory uncertainty-must be addressed before widespread clinical implementation can be achieved. This narrative review integrates current knowledge of exosome biology, diagnostic and therapeutic applications, and engineering strategies. It further examines major translational barriers and outlines future priorities for advancing exosome-based technologies toward precision medicine.\n\nID: 42589601\nTitle: Grape-Derived Exosome-like Nanoparticles Ameliorate Prediabetes in Mice via Amino Acid Metabolic Reprogramming.\nAbstract: This study investigates the effects of grape-derived exosomes on prediabetic mice and elucidates their underlying mechanisms through an integrated metabolomics approach. A prediabetic mouse model was established, with 18 mice randomly assigned to three groups: model control group, grape exosome treatment group, and antioxidant nutrient supplementation group. Therapeutic efficacy was assessed using fasting plasma glucose (FPG) and homeostasis model assessment of \u03b2-cell function (HOMA-\u03b2). Intestinal content metabolites were profiled via both untargeted ultra-high performance liquid chromatography coupled with orbitrap electrospray mass spectrometry (UHPLC-OE-MS) and targeted metabolomics analyses. Grape exosomes effectively mitigated prediabetes progression. Untargeted metabolomics revealed 1222 downregulated and 425 upregulated metabolites in the grape exosome group relative to the model control group, among which riboflavin (upregulated) was potentially associated with amino acid metabolism. Targeted metabolomics identified 23 upregulated and 41 downregulated metabolites, with glycine showing a significant elevation. Notably, both the grape exosome group and antioxidant nutrient supplementation group exhibited increased glycine levels and shared enriched metabolic pathways, including D-glutamine and D-glutamate metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, as well as valine, leucine, and isoleucine biosynthesis. Integrated untargeted and targeted metabolomics analysis demonstrates that grape exosomes ameliorate diabetes-related metabolic disorders and slow the progression of prediabetes, indicating that grape-derived exosomes have great potential as a functional intervention agent for early glucose metabolism dysfunction.\n\nID: 42589286\nTitle: Exercise and Ferroptosis in Neurodegenerative Diseases: Direct Evidence, Mechanistic Links, and Translational Gaps.\nAbstract: Ferroptosis is an iron-dependent form of regulated cell death characterized by iron dyshomeostasis, glutathione depletion, glutathione peroxidase 4 dysfunction, and excessive lipid peroxidation. Exercise is a safe and accessible non-pharmacological intervention with broad neuroprotective potential, but the evidentiary basis linking exercise specifically to ferroptosis is uneven. Only a limited subset of studies directly combines an exercise intervention with ferroptosis-related outcomes in neurodegenerative models; much of the proposed pathway architecture is inferred from pharmacological, cellular, observational, or acute neurological injury studies. This review therefore separates direct exercise evidence from exercise-related supporting evidence and non-exercise mechanistic evidence. The most directly relevant findings, concentrated largely in aerobic exercise models, show exercise-associated changes in brain iron handling, the cystine/glutamate antiporter-glutathione peroxidase 4 antioxidant system, and lipoxygenase-dependent lipid peroxidation. Supporting studies suggest additional peripheral-to-central mechanisms involving muscle-derived exosomes, exercise-associated changes in systemic and cerebral iron handling, and inflammatory regulation. Bone marrow hematopoiesis, adult neurogenesis, synaptic plasticity, and astrocyte-controlled iron traffic are incorporated as biologically plausible but incompletely tested links. Evidence for resistance training, high-intensity interval training, mind-body exercise, and human disease remains insufficient. The central limitation is therefore not pathway plausibility but the scarcity of exercise-specific causal experiments demonstrating that ferroptosis suppression is required for neuroprotection.\n\nID: 42563691\nTitle: XBP1 signaling from tumor metabolic stress to myeloid driven immunotherapy resistance (Review).\nAbstract: The tumor microenvironment (TME) is a complex ecosystem with harsh conditions, such as hypoxia, nutrient deprivation, metabolic acidosis and oxidative stress, that promote tumor progression and shape immune responses. In this environment, endoplasmic reticulum stress and the unfolded protein response are activated, with the transcription factor X\u2011box binding protein 1 (XBP1) serving a key role. XBP1 not only maintains cell protein homeostasis, but also modulates the generation, metabolic adaptation and immunosuppressive function of myeloid\u2011derived suppressor cells (MDSCs). The TME and tumor\u2011derived factors, such as exosomes, remotely activate XBP1 in MDSCs, enhancing their survival and immunosuppressive capability by reprogramming lipid and glucose metabolism and upregulating the expression of arginase\u20111, inducible nitric oxide synthase, reactive oxygen species and immunosuppressive cytokines. The present review aimed to describe the TME stress\u2011XBP1\u2011MDSC\u2011immunosuppression axis, its molecular mechanisms and the role of XBP1 in MDSC heterogeneity and plasticity. Targeting XBP1 may enhance the efficacy of existing therapies, particularly immune checkpoint blockade, by alleviating MDSC\u2011mediated immunosuppression, offering a novel paradigm for understanding and reversing tumor immune escape.\n\nID: 42556769\nTitle: Mitochondria-enriched BMSC exosomes restore microglia-neuron cross-talk in Parkinson's disease via PINK1/parkin and PI3K/Akt/mTOR pathways.\nAbstract: Mitochondrial dysfunction and neuroinflammation drive dopaminergic neuron loss in Parkinson's disease (PD). While BMSC-derived small extracellular vesicles (BMSC-Exo) are neuroprotective, their ability to repair mitochondrial deficits is limited. We engineered mitochondrial-enriched sEVs (Exo-Mito) to evaluate their effects on microglia-neuron interactions in a PD-relevant model. BMSC-Exo-Mito were characterized via TEM, NTA, and immunoblotting. Their therapeutic efficacy was assessed using an MPP\u00a0+\u00a0-induced BV2/SH-SY5Y transwell co-culture model. Assessments included ROS levels, mitochondrial membrane potential, ATP quantification, mitophagy flux, and signaling pathway analysis. Exo-Mito significantly restored mitochondrial homeostasis by reducing ROS, preserving membrane potential, and increasing ATP production. Mechanistically, Exo-Mito enhanced PINK1/Parkin-dependent mitophagy and PGC-1alpha/TFAM-mediated biogenesis. In BV2 microglia, Exo-Mito suppressed the NF-kappaB/NLRP3 axis, reduced proinflammatory cytokines, and promoted M2 polarization. In SH-SY5Y cells with dopaminergic phenotype, Exo-Mito was associated with reactivated PI3K/Akt/mTOR signaling, preserved tyrosine hydroxylase expression, and inhibited apoptosis. Functionally, Exo-Mito improved SH-SY5Y cell and restored microglial migratory capacity, showing superior efficacy to unmodified BMSC-Exo. Mitochondria-enriched BMSC sEVs protect SH-SY5Y cells by coordinating mitochondrial quality control and modulating neuroinflammation. These findings support Exo-Mito as a promising cell-free therapeutic strategy for Parkinson's disease.\n\nID: 42549970\nTitle: Condensates on the Move: Midbody Remnants as Large, Translation-Competent Extracellular Vesicles.\nAbstract: Recent work has expanded understanding of extracellular vesicle (EV) biology by identifying midbody remnants (MBRs) as large, translationally competent vesicles released during mitosis. MBRs contain ribosomes, mitochondria, translation factors, and selected mRNAs and small RNAs concentrated within a condensate\u2011like ribonucleoprotein core and can support protein synthesis after extracellular release. These features distinguish MBRs from more extensively studied exosomes and microvesicles yet also place them within a broader continuum of large EVs with organelle\u2011rich, cell\u2011like properties. This review summarizes current knowledge of MBR biogenesis, molecular organization, and translation competency; contrasts MBRs with canonical EVs and other large EVs; and discusses possible roles in development, tissue homeostasis, disease, and brain function. Particular emphasis is placed on outstanding mechanistic and physiological questions, including how MBR translation is regulated, which recipient cells interact with endogenous MBRs, and whether translation\u2011competent EVs offer practical advantages over existing EV platforms for therapeutic or biotechnological applications.\n\nID: 42536806\nTitle: Tumor-Derived Exosomal circAP2B1 Induces M2 Macrophage Polarization by Enhancing Mitochondrial Homeostasis to Promote Esophageal Squamous Cell Carcinoma Progression.\nAbstract: Esophageal squamous cell carcinoma (ESCC) remodels the immunosuppressive tumor microenvironment via exosome-mediated intercellular communication. In this study, circular RNA circAP2B1 is identified as a critical regulatory molecule that is markedly upregulated in ESCC tissues and patient serum and strongly associated with poor prognosis. Mechanistically, tumor-derived exosomes efficiently deliver circAP2B1 to tumor-associated macrophages (TAMs), where it serves as a distinct molecular scaffold that simultaneously binds the transcription factor ESRRA and the nuclear import receptor KPNA1, facilitating ternary complex formation and ESRRA nuclear translocation. Once in the nucleus, ESRRA directly activates the transcription of Mitofusin 2 (MFN2), a pivotal regulator of mitochondrial fusion, thereby enhancing mitochondrial oxidative phosphorylation, improving ATP production efficiency, and establishing a metabolically optimized intracellular environment that ultimately drives TAMs toward a pro-tumor M2 phenotype. Both in vitro and in vivo experiments demonstrate that targeted intervention of the circAP2B1/ESRRA/KPNA1/MFN2 signaling axis effectively reverses M2 polarization and markedly suppresses tumor progression. This study uncovers a novel exosomal circRNA-mediated metabolic-immune regulatory pathway and offers new avenues for the diagnosis and treatment of ESCC. The findings not only expand the understanding of circRNA functions in tumor immunity but also provide a theoretical basis for the development of therapies targeting the metabolic-immune axis.\n\nID: 42530066\nTitle: FDX1 expression promotes DSF/Cu-induced cuproptosis in gastric cancer cells.\nAbstract: Gastric cancer (GC) is a prevalent malignant tumor that warrants the development of drugs and therapeutic targets. Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC. Moreover, the combination of NK cell exosomes with DSF/Cu improved the therapeutic effect of DSF/Cu, which helps to promote the targeted therapy of GC and improve clinical applicability.\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.

Previous understanding of the underlying mechanism focused on the impairment of lysosome biogenesis caused by TMEM106B loss-of-function. However, mutations in TMEM106B increase its expression level, thus the molecular process linking these mutations to the apparent disruption in TMEM106B function remains mysterious. Recent new studies reported that TMEM106B proteins form intracellular amyloid filaments which universally exist in various neurodegenerative diseases, sometimes being the dominant form of protein aggregation. In light of these new findings, in this review we systematically examined previous efforts in understanding the function of TMEM106B in physiological and pathological conditions. We propose that TMEM106B aggregations could recruit normal TMEM106B proteins and interfere with their function. TMEM106B mutations could lead to lysosome dysfunction by promoting the aggregation of TMEM106B and reducing these aggregations may restore lysosomal function, providing a potential therapeutic target for various neurodegenerative diseases.\n --- END ACTUAL ABSTRACT FOR 37563705 ---\n\n- ERROR: You cited ID: 42533037 for the quote: \"Hippocampal neuronal progranulin (PGRN), a secreted neuroprotective glycoprotein, as a key regulator of affective resilience...

Mitophagy, the selective degradation of damaged or superfluous mitochondria, plays a central role in maintaining mitochondrial integrity and metabolic balance. This review provides a comprehensive overview of the best-characterized PINK1-PRKN/parkin-dependent mitophagy pathway and the expanding repertoire of PRKN-independent mechanisms, including additional ubiquitin-dependent, receptor-mediated, and lipid-mediated pathways. We explore how these pathways intersect and compensate for one another, highlighting the complexity and adaptability of mitochondrial quality control networks. Furthermore, we discuss how dysregulated mitophagy contributes to the onset and progression of neurodegenerative diseases. By examining the interplay between mitophagy pathways and their regulation under physiological and pathological conditions, this review underscores the therapeutic potential of targeting mitophagy in neurodegeneration. Future studies should aim to decode the spatiotemporal dynamics of these pathways to uncover novel opportunities for clinical intervention.Abbreviations: AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; AMBRA1: autophagy and beclin 1 regulator 1; AMFR/GP78: autocrine motility factor receptor; AMPK: AMP-activated protein kinase; ARIH1: ariadne RBR E3 ubiquitin protein ligase 1; ATG: autophagy related; A\u03b2: amyloid beta; BCL2L13: BCL2 like 13; BNIP3: BCL2 interacting protein 3; BNIP3L/NIX: BCL2 interacting protein 3 like; CALCOCO2/NDP52: calcium binding and coiled-coil domain 2; CAMc: core autophagy machinery components; CSNK2/CK2: casein kinase 2; DUB: deubiquitinase; DNM1L/DRP1: dynamin 1 like; FKBP8: FKBP prolyl isomerase 8; FUNDC1: FUN14 domain containing 1; GABARAP: GABA type A receptor-associated protein; GLP-1: glucagon-like peptide 1; HD: Huntington disease; HUWE1: HECT, UBA and WWE domain containing E3 ubiquitin protein ligase 1; IMM: inner mitochondrial membrane; iPSC: induced pluripotent stem cell; LIR: LC3-interacting region; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARCHF5: membrane associated ring-CH-type finger 5; MCL1: MCL1 apoptosis regulator, BCL2 family member; MDV: mitochondria-derived vesicle; MFN1: mitofusin 1; MFN2: mitofusin 2; MQC: mitochondrial quality control; mtDNA: mitochondrial DNA; MUL1: mitochondrial E3 ubiquitin protein ligase 1; NBR1: NBR1 autophagy cargo receptor; OMM: outer mitochondrial membrane; OMMAD: outer mitochondrial membrane-associated degradation; OPA1: OPA1 mitochondrial dynamin like GTPase; OPTN: optineurin; OXPHOS: oxidative phosphorylation; PARL: presenilin associated rhomboid like; PD: Parkinson disease; PE: phosphatidylethanolamine; PG: phagophore; PGAM5: PGAM family member 5, mitochondrial serine/threonine protein phosphatase; PINK1: PTEN induced kinase 1; PPARGC1A/PGC-1\u03b1: PPARG coactivator 1 alpha; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PtdIns3K: phosphatidylinositol 3-kinase; RB1CC1/FIP200: RB1 inducible coiled-coil 1; RHOT1/Miro1: ras homolog family member T1; ROS: reactive oxygen species; SIAH1: siah E3 ubiquitin protein ligase 1; SMURF1: SMAD specific E3 ubiquitin protein ligase 1; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TAX1BP1: Tax1 binding protein 1; TBK1: TANK binding kinase 1; TCA: tricarboxylic acid cycle; TFAM: transcription factor A, mitochondrial; TIMM: translocase of inner mitochondrial membrane; TOMM: translocase of outer mitochondrial membrane; Ub: ubiquitin; ULK1: unc-51 like autophagy activating kinase 1; UPRmt: mitochondrial unfolded protein response; UPS: ubiquitin-proteasome system; USP30: ubiquitin specific peptidase 30; VCP: valosin containing protein; VDAC: voltage dependent anion channel; WIPI: WD repeat domain, phosphoinositide interacting.\n --- END ACTUAL ABSTRACT FOR 42533617 ---\n\n- ERROR: You cited ID: 42539297 for the quote: \"targeted small molecule and genetic modulation of THPO, IGF1, or MAPK recapitulated the significant therapeutic benefit of CHX in PMD.\"\n FACT: Strict Misquote Detected!

Cycloheximide (CHX) is a global cytosolic translation inhibitor we previously reported to rescue PMD preclinical models, although its toxicity precluded clinical development. To identify specific mediators underlying CHX treatment benefit in PMD, SOMAscan-based proteomics was performed in complex I deficient and genetic disease fibroblast cell line models grown in galactose. Thrombopoietin (THPO) and insulin-like growth factor binding protein 5 (IGFBP5) were the only two differentially regulated proteins, together with ERK/MAPK pathway dysregulation, identified upon CHX treatment in PMD versus healthy control cells. THPO inhibition by siRNA or pharmacologic approaches rescued stress-induced viability loss in patient fibroblasts having diverse PMD gene etiologies, and significantly improved mitochondrial stress, linear growth, and neuromuscular function in a classical ndufs2 -/- C. elegans model. IGFBP5 overexpression by lentiviral or mRNA approaches rescued cell viability across distinct PMD gene etiologies, as did IGF1 pharmacologic inhibition across both PMD mutant and C. elegans models. MAPK pharmacologic inhibition rescued multiple distinct complex I disease cells' survival, as well as mitochondrial stress in SLC25A46 -/- C. elegans . Combination therapies targeting multiple of these glucose signaling pathway proteins, together with glucose and N-acetylcysteine, yielded superior therapeutic benefit in complex I disease cell and C. elegans models. Additionally, single or combined pharmacologic inhibition of THPO or IGF1 significantly enhanced primary and metastatic osteosarcoma cell death. Collectively, targeted small molecule and genetic modulation of THPO, IGF1, or MAPK recapitulated the significant therapeutic benefit of CHX in PMD, while avoiding global translation inhibition. These novel PMD therapies likely confer benefit by attenuating MAPK-driven autophagy and potentially promoting noncanonical glucose uptake, improving cellular energy balance. Overall, these glucose signaling cellular pathway targets hold broad therapeutic promise for PMD patients, warranting further clinical research development.\n --- END ACTUAL ABSTRACT FOR 42539297 ---\n\n- ERROR: You cited ID: 42530260 for the quote: \"The integrated evaluation of these mechanisms demonstrates that 4H-pyran-based acids can act as multitarget neuroprotective agents.\"\n FACT: Strict Misquote Detected!

In recent years, compounds belonging to the 4H-pyran chemical class have attracted significant attention due to their pronounced antioxidant, anti-inflammatory, and cytoprotective properties. These molecules exhibit structural versatility, enabling modulation of multiple molecular targets involved in neuronal survival, redox homeostasis, and mitochondrial function. This review provides a comprehensive analysis of the pharmacological activity and molecular mechanisms of action of five 4H-pyran-based compounds-maltol, kojic acid, chelidonic acid, comenic acid, and meconic acid. Special attention is paid to their effects on signaling pathways that play a central role in maintaining neuronal integrity and resistance to stress factors. In particular, the review examines how these compounds regulate key intracellular cascades such as nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1)/antioxidant response element (ARE), Nrf2/PTEN-induced putative kinase 1 (PINK1)/Parkin, nuclear factor-kappa B (NF-\u03baB), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR), which are critically involved in controlling oxidative stress, mitochondrial autophagy, inflammation, and neuronal plasticity. The integrated evaluation of these mechanisms demonstrates that 4H-pyran-based acids can act as multitarget neuroprotective agents capable of influencing both primary metabolic processes and secondary signaling responses to neurotoxic stimuli. Their pleiotropic action highlights the promise of these compounds as molecular scaffolds for the development of novel drugs aimed at preventing or delaying the progression of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases.\n --- END ACTUAL ABSTRACT FOR 42530260 ---\n\n- ERROR: You cited ID: 42519007 for the quote: \"Integrated metagenomics and metabolomics to characterize gut microecology in 28 patients with AD and 33 controls.\"\n FACT: Strict Misquote Detected!

We applied integrated metagenomics and metabolomics to characterize gut microecology in 28 patients with AD and 33 controls. Metagenomic analysis revealed distinct microbial community structures, with increased abundance of Akkermansia massiliensis, Alistipes onderdonkii, and Barnesiella intestinihominis in AD. Phageome analysis revealed increased richness and altered composition, with more Podoviridae and fewer Microviridae. Functional profiling identified shifts in microbial metabolic pathways involving tryptophan and short-chain fatty acid metabolism. Untargeted metabolomics revealed elevated fecal spermidine, taurocholate, and glycerophosphocholine levels in patients with AD. A random forest model combining metabolites, gut metabolic modules, and bacteriophages achieved good within-cohort classification (AUC = 0.83) but lacked external validation due to unavailable matched fecal metabolomic data. Overall, these findings link AD to coordinated disruptions across bacterial, viral, and metabolic gut layers, highlighting the need for external validation and mechanistic studies.\n --- END ACTUAL ABSTRACT FOR 42519007 ---\n\n- ERROR: You cited ID: 42511092 for the quote: \"Goose astrovirus (GoAstV) infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux.\"\n FACT: Strict Misquote Detected!

This research investigates the role of autophagy in renal damage caused by GoAstV in goslings. The findings indicated that GoAstV infection in goslings resulted in characteristic clinical manifestations, with renal tissues displaying tubular swelling, inflammatory infiltration, and autophagosome formation. In vivo experiments demonstrated a significant upregulation of mRNA levels for autophagy-related factors, including AMPK, LC3A, ATG5, ATG7, P62, Beclin1, AMBRA1 and GABARAPL1, while mTOR and LC3B levels were notably decreased. At 3 dpi, the protein expression levels of ATG5, Beclin1, and LC3B II/I increased, while P62 levels decreased, suggesting autophagy activation. In vitro analyses revealed that GoAstV infection led to enhanced autophagy; however, the concurrent upregulation of LC3B II/I and P62 proteins suggested an obstruction in the autophagic flux. Upon the inhibition of autophagy with 3-methyladenine (3-MA, autophagy inhibitor), there was a significant reduction in the expression of autophagy-related factors, accompanied by a marked decrease in viral replication rates. In conclusion, GoAstV infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux. The virus exploits autophagosomes for replication, ultimately resulting in kidney damage. The application of 3-MA effectively inhibits this autophagic process and diminishes viral replication.\n --- END ACTUAL ABSTRACT FOR 42511092 ---\n\n- ERROR: You cited ID: 42510853 for the quote: \"Integrating FUMA positional mapping, MAGMA gene-level association and TWAS expression-level association prioritized eight convergent genes: TMEM106B...

Methods: We applied genomic structural equation modeling to European-ancestry GWAS summary statistics for five constituent phenotypes: depressive symptoms, depression diagnosis, grip strength, appendicular lean mass, and walking pace. A Depression-Physical Function shared genetic factor was constructed as a cross-trait genetic covariance dimension and evaluated using LDSC-based validation and leave-one-trait-out sensitivity analyses. We then performed factor GWAS, FUMA locus annotation, Bayesian fine-mapping, MAGMA gene-based analysis, transcriptome-wide association analysis, pathway enrichment, CELLECT/MAGMA cell-type specificity analysis, partitioned heritability analysis, and gsMap spatial transcriptomic mapping. Results: The shared factor showed good model fit and retained 755,397 quality-controlled variants for downstream analysis. The factor was positively genetically correlated with depression-related traits and negatively correlated with physical-function-related traits. FUMA identified 245 genome-wide significant SNPs, 44 lead SNPs, and 38 genomic risk loci, with 127 positional mapped genes. Fine-mapping prioritized one high-confidence locus. MAGMA identified 19 Bonferroni-significant genes and 326 FDR-significant genes, while TWAS identified 322 FDR-significant expression-associated genes. Integrating FUMA positional mapping, MAGMA gene-level association and TWAS expression-level association prioritized eight convergent genes: TMEM106B, CENPW, DRD2, LRFN5, NCAPG, DCAF16, SGIP1, and FAM120A. Functional enrichment highlighted postsynaptic structure, neuron spine, synaptic plasticity, and synapse organization. CELLECT/MAGMA prioritized brain non-myeloid neurons and glial populations, with additional endocrine-metabolic and immune-hematopoietic signals. Spatial transcriptomic mapping localized top signals to brain and spinal cord regions in the embryonic neuro-muscle reference. Partitioned heritability analysis showed enrichment in conserved, intronic, promoter, and chromatin-related genomic annotations. Conclusions: These findings support a shared polygenic covariance dimension linking depression-related liability with reduced physical-function-related genetic propensity. Downstream analyses prioritized candidate loci, genes, and biological contexts, with enrichment patterns consistent with neuronal, synaptic, and regulatory genomic processes.\n --- END ACTUAL ABSTRACT FOR 42510853 ---\n\n- ERROR: You cited ID: 42510787 for the quote: \"LIG4 and ZRANB3 were identified as key genes... associated with ERS and autophagy in MCD.\"\n FACT: Ellipses (...) are strictly forbidden.

Endoplasmic reticulum stress (ERS) and autophagy are implicated in its pathogenesis, but the precise mechanisms remain unclear. This study aimed to identify ERS and autophagy-related key genes (ERS-RGs and ARGs) in MCD using bioinformatic and experimental approaches. Methods: Transcriptomic data from GSE216841 and GSE246206 were analyzed. ERS-RGs and ARGs were obtained from prior literature. Candidate genes were selected by integrating weighted gene coexpression network analysis and differential expression analysis. Feature genes were identified via protein-protein interaction network analysis and machine learning (Least Absolute Shrinkage and Selection Operator and Boruta). Key genes were validated by expression analysis and receiver operating characteristic evaluation. A multilayer perceptron (MLP) model was constructed, and regulatory networks, immune infiltration, and chemical compound prediction were analyzed. The expression levels of the identified key genes were preliminarily assessed in peripheral blood samples using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Results:LIG4 and ZRANB3 were identified as key genes, both significantly downregulated in the MCD group, and the gene-based MLP model effectively predicted MCD probability. Overall, 13 significantly different immune cell types (e.g., CD56+ natural killer and activated dendritic cells) were detected. Regulatory networks (transcription factor-messenger RNA (mRNA) and long non-coding RNA-microRNA-mRNA) and 8 common chemical compounds (e.g., bisphenol A, acetaminophen) targeting these genes were predicted. Notably, peripheral blood RT-qPCR analysis revealed significant LIG4 and ZRANB3 downregulation, suggesting a systemic expression signature. Conclusions:LIG4 and ZRANB3 are key genes associated with ERS and autophagy in MCD, providing insights for diagnosis and targeted therapy.\n --- END ACTUAL ABSTRACT FOR 42510787 ---\n\n- ERROR: You cited ID: 42507332 for the quote: \"Nose-to-brain (N2B) delivery has emerged as a non-invasive strategy to transport therapeutics to the central nervous system through the olfactory and trigeminal pathways.\"\n FACT: Strict Misquote Detected!

Nose-to-brain (N2B) delivery has emerged as a non-invasive strategy to transport therapeutics to the central nervous system through the olfactory and trigeminal pathways, thereby partially bypassing the blood-brain barrier. Recent advances in nanomedicine and biomaterial engineering have further improved this approach by enhancing drug stability, nasal residence, mucosal transport, and brain-targeting efficiency. This review examines nanocarrier-enabled N2B delivery strategies for AD from a mechanism-guided perspective, highlighting how AD-related pathological processes shape the selection of therapeutic cargos and formulation designs. We discuss recent progress in the intranasal delivery of repurposed small molecules, natural products, insulin-related agents, peptides and proteins, extracellular vesicles, antibodies, and nucleic acid-based therapeutics. We further summarize major nanocarrier and formulation platforms, including lipid-based systems, polymeric nanoparticles, micelles, extracellular vesicles, in situ gels, and device-assisted delivery technologies. Particular attention is given to the design parameters that influence N2B performance, including particle size distribution/PDI, surface charge, mucus interaction, cargo protection, targeting modification, biodistribution, and deposition reproducibility. Finally, we critically evaluate the translational challenges that continue to limit clinical application, including species differences in nasal anatomy, dose-volume restrictions, device-dependent variability, limited human pharmacokinetic evidence, manufacturing complexity, long-term safety, and regulatory requirements. By integrating disease mechanisms, nanocarrier design, and translational considerations, this review provides a structured perspective for developing more rational and clinically feasible N2B nanodelivery systems for AD.\n --- END ACTUAL ABSTRACT FOR 42507332 ---\n\n- ERROR: You cited ID: 42488829 for the quote: \"Preclinical evidence demonstrates that ginseng and its active constituents attenuate key pathological processes, including oxidative stress, inflammatory responses, apoptosis, and autophagy dysregulation.\"\n FACT: Strict Misquote Detected!

Panax ginseng and its related preparations, including major ginsenosides (e.g., Rb1, Rg1, and Rg3), standardized extracts, and compound formulas, have garnered growing interest owing to their multi-component, multi-target pharmacological activities and integrative regulatory effects. This review systematically summarizes recent advances in the basic and clinical research of ginseng-based medicines in the prevention and treatment of cardiac fibrosis. Preclinical evidence demonstrates that ginseng and its active constituents attenuate key pathological processes, including oxidative stress, inflammatory responses, apoptosis, and autophagy dysregulation, primarily through modulation of signaling pathways such as TGF-\u03b2/Smad, NF-\u03baB, and PI3K/Akt. These regulatory effects collectively contribute to the inhibition of fibroblast activation, reduction of collagen deposition, and improvement of myocardial structure and function. Emerging clinical studies further suggested potential benefits in improving cardiac function and modulating fibrosis-related biomarkers in patients with hypertension, coronary heart disease, and heart failure (HF). Despite these promising findings, several challenges hinder clinical translation, including low oral bioavailability, the mechanistic complexity of compound formulas, and insufficient high-quality clinical evidence. Future investigations should integrate novel drug delivery strategies, systems pharmacology approaches to elucidate holistic mechanisms, and well-designed randomized controlled trials to facilitate the development of ginseng-based medicines as potential therapeutic agents for cardiac fibrosis.\n --- END ACTUAL ABSTRACT FOR 42488829 ---\n\n- ERROR: You cited ID: 42486454 for the quote: \"YSTLF's mechanism of action involves regulation of the AMPK/mTOR signaling pathway and restoration of the balance between autophagy and apoptosis.\"\n FACT: Strict Misquote Detected!

It has been used clinically to treat oligoasthenozoospermia (OAS) for more than two decades, with proven efficacy and a favorable safety profile. However, its precise molecular mechanism has yet to be fully elucidated. The aim was to investigate the therapeutic efficacy and the underlying mechanism of YSTLF in treating OAS associated with the kidney deficiency and collateral obstruction pattern. The chemical constituents of YSTLF were identified by UHPLC-Q-Orbitrap HRMS, and molecular docking was performed between the ten most abundant compounds and AMPK/mTOR. Rat OAS models were established by combined GTW, adrenaline, and ice-water immersion. Pharmacodynamic effects were evaluated through general status, reproductive organ weights, sperm quality, coagulation parameters, and serum sex hormones. Testicular histopathology, ultrastructure, and autolysosomes were examined by HE staining and TEM. Apoptosis was detected by TUNEL staining, and autophagy/apoptosis-related protein expression by IHC. Integrated metabolomics and proteomics with KEGG enrichment were conducted. In GTW-injured GC-1spg cells treated with Compound C or rapamycin, CCK-8 assay assessed viability, flow cytometry evaluated apoptosis, immunofluorescence examined LC3B/cleaved caspase-3 expression and colocalization, and Western blotting/RT-qPCR validated AMPK/mTOR pathway key molecules. Among 307 identified compounds (mostly flavonoids), YSTLF improved general status, organ weights, and sperm quality in model rats. The ten most abundant compounds showed binding energies < -7.0\u202fkcal/mol for AMPK/mTOR. Sperm concentration and motility increased dose-dependently. PT and TT were prolonged, FIB decreased, and FSH, LH, T, PRL, and Inh-B were restored. H&E, TEM, and TUNEL revealed alleviated testicular pathology, improved ultrastructure, reduced autolysosomes, and decreased apoptosis. IHC showed downregulated Beclin1 and Bax, and upregulated p62 and Bcl-2. Multi-omics revealed co-enrichment of differential proteins/metabolites in autophagy and mTOR pathways. Western blot/RT-qPCR validated downregulated p-AMPK/AMPK, AMPK mRNA, LC3II, Beclin1, Bax, cleaved caspase-3, and cleaved caspase-3/caspase-3 ratio, alongside upregulated p-mTOR/mTOR, mTOR mRNA, p62, and Bcl-2. In vitro, GTW reduced viability concentration-/time-dependently (stable model: 10%/24\u202fh); YSTLF reversed this (optimal: 15%/24\u202fh), restored viability, reduced apoptosis, and decreased LC3B/cleaved caspase-3 fluorescence/colocalization, while downregulating p-AMPK, LC3II, Bax and upregulating p-mTOR, p62, Bcl-2. Compound C alone mimicked YSTLF's effects without additivity, whereas rapamycin aggravated GTW-induced viability loss, apoptosis, and autophagy/apoptosis co-activation. YSTLF improved spermatogenic function in rats with OAS (kidney deficiency and collateral obstruction pattern). Its mechanism of action involves regulation of the AMPK/mTOR signaling pathway and restoration of the balance between autophagy and apoptosis.\n --- END ACTUAL ABSTRACT FOR 42486454 ---\n\n- ERROR: You cited ID: 42486831 for the quote: \"BBP protects against LPS-induced ALI in mice possibly by targeting the Nrf-2/HO-1 and NF-\u03baB pathways.\"\n FACT: Strict Misquote Detected!

Cultured RAW264.7 cells were pretreated with, different concentrations of BBP, or dexamethasone (Dex) for 1 h before LPS challenge. Sixty male C57BL/6 mice were randomized into 5 groups (n=12), including a control group, a LPS-induced ALI model group, a Dex treatment group, and two BBP treatment groups treated with low- (30 mg/kg) or high-dose (120 mg/kg) BBP. The levels of inflammatory factors and oxidative stress-related indicators in the cells and mouse lung tissues were determined, and mouse lung histopathology, wet/dry weight ratio, and BALF cell count were examined; the expressions of NF-\u03baB and Nrf-2/HO-1 pathways were detected using qPCR, Western blotting, and immunohistochemistry. In LPS-stimulated RAW264.7 cells, BBP (12.5 \u03bcg/mL) significantly reduced the levels of TNF-\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, NO and ROS, enhanced SOD activity, increased mRNA expressions of I\u03baB-\u03b1, Nrf-2, and HO-1, and lowered mRNA expressions of TNF-\u03b1, IL-1\u03b2, Keap-1, and NF-\u03baB (p65). The ALI mouse models showed severe lung pathologies and edema, increased BALF cell counts, and increased levels of TNF\u2011\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, and NO, lowered SOD activity with reduced protein expressions of I\u03baB-\u03b1, Nrf-2, and HO-1 and increased expressions of Keap-1 and p65. Treatment with high-dose BBP significantly ameliorated lung pathologies in the mouse models and improved the aberrant alterations in pulmonary expressions of inflammatory factors, oxidative stress-related indicators and the NF-\u03baB and Nrf-2/HO-1 pathways. BBP protects against LPS-induced ALI in mice possibly by targeting the Nrf-2/HO-1 and NF-\u03baB pathways, suggesting its potential as a therapeutic agent for ALI. \u76ee\u7684: \u63a2\u7a76\u718a\u80c6\u7c89\uff08BBP\uff09\u901a\u8fc7\u8c03\u63a7NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u5bf9\u8102\u591a\u7cd6\u8bf1\u5bfc\u7684\u6025\u6027\u80ba\u635f\u4f24\uff08ALI\uff09\u5c0f\u9f20\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u4f53\u5916\u5b9e\u9a8c:\u91c7\u7528\u8102\u591a\u7cd6\uff08LPS\uff09\u8bf1\u5bfcRAW264.7\u7ec6\u80de\u5efa\u7acb\u4f53\u5916\u6a21\u578b\uff0c\u8bbe\u7f6e\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001\u5730\u585e\u7c73\u677e\uff08Dex\uff0c25 \u03bcg/mL\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff086.25 \u03bcg/mL\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff0812.5 \u03bcg/mL\uff09\u3002\u4f53\u5185\u5b9e\u9a8c:\u5c0660\u53eaC57BL/6\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001Dex\u7ec4\uff085 mg/kg\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff0830 mg/kg\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff08120 mg/kg\uff09\uff0c12\u53ea/\u7ec4\u3002\u901a\u8fc7ELISA\u548c\u76f8\u5173\u8bd5\u5242\u76d2\u68c0\u6d4b\u7ec6\u80de\u548c\u80ba\u7ec4\u7ec7\u4e2d\u708e\u75c7\u4e0e\u6c27\u5316\u5e94\u6fc0\u6307\u6807;\u901a\u8fc7\u80ba\u7ec4\u7ec7\u75c5\u7406\u5206\u6790\u3001\u514d\u75ab\u7ec6\u80de\u8ba1\u6570\u548c\u80ba\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u7b49\u6307\u6807\u8bc4\u4ef7BBP\u5bf9ALI\u7684\u5e72\u9884\u4f5c\u7528\u3002\u901a\u8fc7qRT-PCR\u3001Western blotting\u548c\u514d\u75ab\u7ec4\u5316\u6cd5\u5206\u6790NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u76f8\u5173\u86cb\u767d\u4e0e\u57fa\u56e0\u7684\u8868\u8fbe\u53d8\u5316\u3002\u7ed3\u679c: \u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\u7ec4\uff0812.5\u03bcg/mL\uff09\u663e\u8457\u964d\u4f4eTNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u4e00\u6c27\u5316\u6c2e\uff08NO\uff09\u548c\u6d3b\u6027\u6c27\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff0c\u4e14I\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff0c\u800cTNF-\u03b1\u3001IL-1\u03b2\u3001Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff08P<0.05\uff0cP<0.01\uff0cP<0.001\uff09\u3002\u52a8\u7269\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u7ed3\u6784\u7d0a\u4e71\uff0c\u80ba\u6ce1\u58c1\u589e\u539a\uff0c\u80ba\u6ce1\u5185\u53ef\u89c1\u5927\u91cf\u708e\u75c7\u7ec6\u80de\u6d78\u6da6\uff0c\u80ba\u7ec4\u7ec7\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u53ca\u652f\u6c14\u7ba1\u80ba\u6ce1\u704c\u6d17\u6db2\uff08BALF\uff09\u603b\u7ec6\u80de\u6570\u5347\u9ad8\uff08P<0.01\uff09;\u80ba\u7ec4\u7ec7\u4e2d\u7684TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u542b\u91cf\u5347\u9ad8\uff0c\u800cSOD\u6d53\u5ea6\u964d\u4f4e\uff08P<0.01\uff0cP<0.001\uff09;\u4e14\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff0cKeap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\uff08120 mg/kg\uff09\u7ec4\u80fd\u6539\u5584\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u75c5\u7406\u635f\u4f24\u72b6\u6001\uff0c\u6539\u5584\u80ba\u80bf\u80c0\u7a0b\u5ea6\uff0c\u964d\u4f4eBALF\u603b\u7ec6\u80de\u6570\u3001TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09;\u540c\u65f6\uff0cBBP\u4e0a\u8c03\u4e86\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u5e76\u6291\u5236\u4e86Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09\u3002\u7ed3\u8bba: BBP\u53ef\u80fd\u901a\u8fc7\u4f5c\u7528\u4e8eNrf-2/HO-1\u548cNF-\u03baB\u4fe1\u53f7\u901a\u8def\u5bf9LPS\u8bf1\u5bfc\u7684ALI\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u540e\u7eed\u7814\u7a76\u6f5c\u5728\u7684\u6cbb\u7597ALI\u836f\u7269\u63d0\u4f9b\u4f9d\u636e\u3002.\n --- END ACTUAL ABSTRACT FOR 42486831 ---\n\n- ERROR: You cited ID: 42486133 for the quote: \"In the largest randomised trial in untreated PCNSL to date, HCT-ASCT significantly improved progression-free and overall survival compared with non-myeloablative consolidation.\"\n FACT: Strict Misquote Detected!

This study aimed to provide randomised comparative evidence on the efficacy and safety of thiotepa-based HCT-ASCT versus non-myeloablative R-DeVIC consolidation after uniform MATRix induction in newly diagnosed PCNSL. This open-label, randomised, phase 3 trial was conducted across 56 university and academic non-university hospitals with established transplantation facilities in five European countries. Eligible for inclusion were untreated, immunocompetent patients with B-cell PCNSL, aged 18-65 years regardless of Eastern Cooperative Oncology Group (ECOG) performance status, or 66-70 years with ECOG performance status 0-2. Pretreatment corticosteroids were permitted. Exclusion criteria included lymphoma manifestation outside the CNS, and congenital or acquired immunodeficiency. Patients received four cycles of MATRix induction (comprising rituximab, high-dose cytarabine, and thiotepa, in addition to high-dose methotrexate). Patients reaching at least partial response were randomly assigned (1:1) to two cycles of R-DeVIC (rituximab plus dexamethasone, etoposide, ifosfamide, and carboplatin) or HCT-ASCT with carmustine and thiotepa. The primary endpoint was progression-free survival, assessed in the full analysis set (excluding patients with major violations of entry criteria). The safety analysis set contained all randomised patients who initiated therapy. This study is registered with ClinicalTrials.gov (NCT02531841) and the EU Clinical Trials Register (EudraCT number 2012-000620-17). The study is completed. Between July 16, 2014, and Aug 31, 2019, 368 patients were enrolled. 346 (94%) patients started induction treatment, and 230 were randomly assigned; 229 patients were analysed (R-DeVIC group, n=115; HCT-ASCT group, n=114). After a median follow-up of 45\u00b73 months, 3-year progression-free survival was significantly superior in the HCT-ASCT group (hazard ratio 0\u00b743 [95% CI 0\u00b727-0\u00b768]; p=0\u00b70003). The 3-year progression-free survival was 78% (95% CI 69-85) in the HCT-ASCT group compared with 51% (41-60) in the R-DeVIC group. The mean number of adverse events per patient was 9\u00b73 (SD 4\u00b74) in the R-DeVIC group and 14\u00b76 (5\u00b78) in the HCT-ASCT group. Fatal serious adverse events following consolidation treatment occurred in two patients in the R-DeVIC group (both acute myeloid leukaemia) and in five patients in the HCT-ASCT group (infections and infestations [n=4], pulmonary embolism [n=1]); all of these events apart from the pulmonary embolism were judged to be possibly related to treatment. In the largest randomised trial in untreated PCNSL to date, HCT-ASCT significantly improved progression-free and overall survival compared with non-myeloablative consolidation in patients who had completed induction treatment, establishing it as the preferred consolidation strategy in fit patients.

A total of 36 male SD rats were randomly assigned to sham operation, model and acupoint pair groups, with 12 rats in each group. The IDD model was established by annulus fibrosus puncture. After modeling, rats of the acupoint pair group received acupuncture stimulation of bilateral SI3 and GB30, with the acupuncture needles retained for 20 min, once daily for 14 consecutive days. Before and after modeling and after the intervention, the mechanical withdrawal reflex threshold (mechanic pain threshold) of the right foot was measured using VonFrey filaments, and the thermal pain threshold measured by using a thermal pain tester. The morphological characteristics of the intervertebral disc tissue were observed by H.E. staining. The contents of type \u2161 collagen (Collagen \u2161), Aggrecan, matrix metalloproteinase 3 (MMP3), matrix metalloproteinase 13 (MMP13), and transcription factor sex-determining region Y-box protein 9 (SOX9) in the nucleus pulposus tissue were detected by ELISA. The mRNA relative expression levels of SOX9 and MMP13 in the nucleus pulposus tissue were detected by real-time fluorescence quantitative PCR. The positive expression of microtubule-associated protein 1 light chain 3 (LC3) in the nucleus pulposus tissue was detected by immunofluorescence staining. The expression levels of PI3K/AKT/mTOR signaling pathway-related proteins and LC3- \u2161, Beclin1, and chaperone 1 (p62) in the nucleus pulposus tissue were detected by Western blot. After modeling, in contrast to the sham operation group, the model group showed a striking decrease in the mechanical and thermal pain thresholds on day 7 and 14, contents of Aggrecan, collagen \u2161 and SOX9, and the expression levels of SOX9 mRNA and p62 protein, ratios of p-PI3K/PI3K, p-AKT/AKT, and p-mTOR/mTOR in the nucleus pulposus tissue (P<0.001, P<0.01), and a notable increase in the contents of MMP3 and MMP13, and MMP13 mRNA expression level, LC3 immunofluorescence intensity, and protein expressions of LC3-\u2161 and Beclin 1 (P<0.001). Under light microscope, the nucleus pulposus cells in the model group was relatively small in the number and discorded in the distribution, with a large number of vacuoles and chaotic matrix arrangement, and the lumbar intervertebral discs showed obvious degeneration, and decrease in the height. In comparison with the model group, both the decrease and increase of the indexes mentioned above were all reversed in the acupoint pair group (P<0.001, P<0.01, P<0.05). The results of H.E. stain displayed that in the acupoint pair group, the arrangement of the nucleus pulposus cells was more regular, and the number of vacuoles was reduced. Acupuncture of acupoint pair SI3 and GB30 can mitigate pain and regulate the autophagy process of lumbar intervertebral disc nucleus cells, reduce the degree of degradation of cytoplasmic matrix, and

To address these problems, a SalB-loaded liquid crystalline nanoparticle delivery system (SalB-LCN) was constructed and systematically characterized in terms of its physicochemical properties. Meanwhile, an intranasal administration strategy was employed to bypass the BBB, and the therapeutic effects of SalB-LCN on VD were systematically evaluated. The results showed that SalB-LCN possessed favorable morphology and sustained-release properties, enabling stable encapsulation and continuous release of SalB. In vitro experiments demonstrated that SalB-LCN exhibited good biocompatibility and could alleviate oxidative damage in neuronal cells. In a bilateral common carotid artery occlusion-induced rat model of VD, SalB-LCN significantly improved learning and memory abilities, alleviated hippocampal neuronal morphological damage, and exhibited good in vivo biosafety. Further studies showed that SalB-LCN markedly lowered reactive oxygen species levels, suppressed IL-1\u03b2 and IL-18 production in hippocampal tissues, and reduced cell death as well as lactate dehydrogenase activity. In addition, SalB-LCN also suppressed NLRP3/Caspase-1/GSDMD signaling. In conclusion, intranasal delivery of SalB-LCN improved brain delivery by facilitating transport across the BBB and conferred neuroprotection against VD through modulation of oxidative stress, inflammation, and NLRP3/Caspase-1/GSDMD signaling, highlighting its translational potential as a nanomedicine-based therapeutic strategy.\n --- END ACTUAL ABSTRACT FOR 42481908 ---\n\n- ERROR: You cited ID: 42480145 for the quote: \"PSS presented pro-angiogenesis effect by mitigating vascular endothelial cell ageing and the underlying mechanisms were involved in the PI3K/AKT/MAPKs, SIRT1/NRF2 and NNMT/MNA signaling pathway.\"\n FACT: Strict Misquote Detected!

Panasenoside (PSS) is a flavonoid glycoside ioslated from Chinese Materia Medica GINSENG RADIX ET RHIZOMA which has been demonstrated with multiple biological activities. However, the pharmacological activity of PSS and the underlying mechanism are still unclear. We found that PSS promoted sub-intestinal vessel plexus (SIVs) growth in zebrafish. PSS ameliorated vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor II (VRI)-induced deficiency of intersegmental vessels (ISVs) in a concentration dependent manner by downregulation of mRNA expression of VEGF receptors, including Kdr/VEGFR-2 (kdr), VEGFR-1 (flt1), and Kdr-like/VEGFR-2 (kdrl), and up-regulation of VEGF (vegfaa). The angiogenesis effect of PSS on VRI-induced ISVs deficiency was suppressed by PI3K, AKT, MEK, ERK, P38, Sirtuin 1 (SIRT1), Nuclear factor erythroid-2-related factor 2 (NRF2) and Nicotinamide N-methyl transferase (NNMT) inhibitors. Activation of NRF2, SIRT1 and MNA significantly restored VRI-induced ISVs insufficiency. In addition, PSS protected against VRI-induced tube formation deficiency in human umbilical vascular endothelial cells (HUVECs). SIRT1, NRF2 and NNMT inhibitors or siRNA eliminated PSS promoting vascular endothelial cell tube formation. PSS also prevented SIRT1, NRF2 and NNMT inhibitors-induced vascular endothelial cell senescence. Furthermore, PSS upregulated the protein expression level of SIRT1 and downregulated its downstreams P53 and PGC-1\u03b1 in HUVECs with high potence of activating SIRT1 by binding with its active domine. In conclusion, PSS presented pro-angiogenesis effect by mitigating vascular endothelial cell ageing and the underlying mechanisms were involved in the PI3K/AKT/MAPKs, SIRT1/NRF2 and NNMT/MNA signaling pathway with SIRT1 acting as a key regulator. We identified the pro-angiogenesis and anti-vascular endothelial cell ageing effects of PSS for the first time, and PSS is a promising drug candidate for treating vascular deficiency associated diseases.\n --- END ACTUAL ABSTRACT FOR 42480145 ---\n\n- ERROR: You cited ID: 42478918 for the quote: \"GlcN promotes lipid clearance in hepatocytes via O-GlcNAc-dependent autophagy and highlight its potential as a therapeutic agent for NAFLD.\"\n FACT: Strict Misquote Detected!

In this study, we examined the effects of glucosamine (GlcN), a hexosamine biosynthetic pathway intermediate, on autophagy and lipid accumulation using both human hepatocellular carcinoma (HepG2) cells and a high-fat diet (HFD)-induced NAFLD mouse model. GlcN treatment led to a dose- and time-dependent increase in the expression of autophagy-related markers LC3 and p62 at both mRNA and protein levels. Pharmacological inhibition of O-GlcNAcase (OGA) further enhanced autophagic activity, whereas inhibition of O-GlcNAc transferase (OGT) abrogated GlcN-induced autophagic responses, implicating O-GlcNAcylation as a key mediator of GlcN-driven autophagy induction. Functionally, GlcN significantly reduced palmitic acid (PA)-induced lipid accumulation in HepG2 cells and alleviated hepatic steatosis in HFD-fed mice, likely through enhancement of autophagic flux. These findings demonstrate that GlcN promotes lipid clearance in hepatocytes via O-GlcNAc-dependent autophagy and highlight its potential as a therapeutic agent for NAFLD and related metabolic disorders.\n --- END ACTUAL ABSTRACT FOR 42478918 ---\n\n- ERROR: You cited ID: 42428020 for the quote: \"MERLIN-SUITE (https://github.com/Roy-lab/MERLIN-SUITE) represents a collection of algorithmic extensions based on MERLIN... a probabilistic framework that infers gene-specific and module-specific regulatory programs.\"\n FACT: Ellipses (...) are strictly forbidden.

MERLIN-SUITE (https://github.com/Roy-lab/MERLIN-SUITE) represents a collection of algorithmic extensions based on MERLIN (Modular regulatory network learning with per gene information) a probabilistic framework that infers gene-specific and module-specific regulatory programs of co-regulated modules, capturing both detailed and modular aspects of transcriptional networks. While expression-based inference is effective, it often aligns poorly with experimentally validated regulatory interactions. MERLIN-P addresses this by integrating external regulatory priors, such as motif, ChIP, and perturbation data, to enhance biological relevance and predictive accuracy. MERLIN-P-TFA further advances the framework by incorporating regularized estimation of latent transcription factor activity (TFA), overcoming the limitation that TF mRNA levels may not represent protein activity. By integrating expression data, prior knowledge, and activity-aware modeling, this unified approach supports robust GRN reconstruction in both bulk and single-cell datasets. This chapter presents the MERLIN-SUITE with a focus on MERLIN-P-TFA and demonstrates its use on a single-cell, multi-modal dataset of mouse cellular reprogramming to infer GRNs and identify key regulators.\n --- END ACTUAL ABSTRACT FOR 42428020 ---\n\n- ERROR: You cited ID: 42311424 for the quote: \"Nanomedicine-based drug delivery systems have emerged as promising strategies to overcome these limitations by enhancing dopamine stability, improving BBB transport, enabling controlled release.\"\n FACT: Strict Misquote Detected!

However, conventional dopaminergic therapies remain limited by poor blood-brain barrier (BBB) penetration, rapid systemic metabolism, short half-life, peripheral toxicity, and dopamine oxidation-induced neurotoxicity. Nanomedicine-based drug delivery systems have emerged as promising strategies to overcome these limitations by enhancing dopamine stability, improving BBB transport, enabling controlled release, and facilitating targeted delivery to dopaminergic brain regions. This review comprehensively summarizes current advances in dopamine-targeted nanotherapeutics, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, dendrimers, inorganic nanoparticles, exosomes, and biomimetic vesicles. Particular emphasis is placed on the dual role of nanocarriers in both facilitating dopamine delivery and protecting dopamine from oxidative degradation and reactive oxygen species-associated toxicity. Among currently investigated platforms, polymeric nanoparticles, lipid-based nanocarriers, and exosome-inspired vesicles appear particularly promising due to their ability to improve dopamine stability, facilitate controlled release, enhance BBB penetration, and enable targeted brain delivery. The review additionally discusses receptor-mediated targeting strategies, intranasal delivery approaches, translational barriers, manufacturing scalability, long-term safety considerations, and regulatory challenges associated with clinical implementation. Finally, emerging future directions involving AI-assisted nanocarrier engineering, precision-targeted delivery systems, and stimuli-responsive nanomedicine are highlighted as promising approaches for the development of next-generation therapies for neurodegenerative disorders.\n --- END ACTUAL ABSTRACT FOR 42311424 ---\n\n- ERROR: You cited ID: 42242508 for the quote: \"Lactoferrin (Lf)-functionalized BXP-loaded nanostructured lipid carrier (Lf-BXP-NLC)... enabled sustained and receptor-mediated nose-to-brain transport.\"\n FACT: Ellipses (...) are strictly forbidden.

To overcome these limitations, a Lactoferrin (Lf)-functionalized BXP-loaded nanostructured lipid carrier (Lf-BXP-NLC) incorporated into a thermoresponsive in situ nasal gel was developed to enable sustained and receptor-mediated nose-to-brain transport. The optimized formulation demonstrated nanoscale particle size (<200 nm), narrow polydispersity, high entrapment efficiency (\u223c88%), and physiological gelation temperature (30-34 \u00b0C), with preserved physicochemical stability over 3 months. In vitro release and ex vivo permeation studies confirmed controlled drug release and enhanced mucosal transport. In vivo pharmacokinetic evaluation in rats revealed significantly improved brain exposure following intranasal administration, with approximately 1.9-fold higher AUCbrain compared with drug suspension and 1.97-fold greater exposure relative to intravenous delivery. A rapid brain Tmax (0.41 h) and direct transport percentage of \u223c 62% indicated dominant neuronal pathway involvement and reduced reliance on systemic circulation. Enhanced pharmacokinetics translated into pronounced pharmacodynamic benefits in ketamine-induced schizophrenia models, including significant attenuation of stereotypic behaviors, restoration of motor coordination, and near-normalization of neuromuscular performance.

Meyer) is a classic herbal medicine widely utilized in dermatological management, yet its precise therapeutic mechanisms have only recently begun to be fully elucidated. This review systematically synthesizes the pharmacological roles of ginseng's active components, including ginsenosides, polysaccharides, and gintonin, in maintaining skin homeostasis and treating various cutaneous pathologies. Emerging evidence suggests that the efficacy of ginseng extends beyond direct molecular interactions, exhibiting the distinct characteristics of \"indirect pharmacology.\" Specifically, parent ginsenosides function primarily as natural prodrugs that require microbial biotransformation into high-affinity active metabolites, such as Compound K and Rh2, to exert potent therapeutic effects. Functionally, these components regulate skin health by mobilizing endogenous host defense systems, particularly through the activation of the Nrf2/ARE antioxidant pathway and the suppression of inflammatory cascades via the NF-\u03baB, MAPK, and IL-1 signaling networks. Furthermore, they remodel the systemic microenvironment through the gut-skin axis, facilitating metabolic homeostasis to improve skin barrier function. Notably, biotransformation rates and ultimate therapeutic efficacy are highly dependent on individualized variables, such as host age, dietary patterns, and baseline disease states. This systemic regulation has demonstrated robust efficacy in intervening in complex pathologies, including atopic dermatitis, psoriasis, and skin cancer. Additionally, this article addresses the translational bottleneck of low bioavailability and evaluates recent advances in novel skin delivery systems, specifically those utilizing ginseng-derived exosomes. Collectively, this review provides a scientific framework for understanding the systemic actions of ginseng, supporting its development as a precision botanical therapy for dermatological applications.\n --- END ACTUAL ABSTRACT FOR 42098749 ---\n\n- ERROR: You cited ID: 42090956 for the quote: \"PEVs protect against DIC by delivering bioactive metabolites to injured myocardium and inhibiting p53-driven oxidative, inflammatory, and apoptotic pathways.\"\n FACT: Strict Misquote Detected!

Panax notoginseng, a traditional medicinal herb, exhibits well-documented cardioprotective properties; however, the therapeutic application of its bioactive constituents is constrained by poor bioavailability and potential toxicity. Plant-derived extracellular vesicles (EVs) have emerged as natural nanocarriers facilitating cross-kingdom delivery of bioactive metabolites. In this study, we investigated whether P. notoginseng-derived EVs (PEVs) could mitigate Dox-induced cardiotoxicity (DIC) and explored the underlying mechanisms. PEVs were isolated from P. notoginseng rhizomes and systematically characterized, with metabolite profiling performed by UPLC-MS. Cellular uptake, biodistribution, and cardioprotective effects were evaluated in Dox-injured cardiomyocytes and a chronic mouse model of DIC. Mechanistic insights were obtained using transcriptomic analysis, molecular docking, and biochemical assays. PEVs were stable nanosized vesicles enriched with characteristic P. notoginseng metabolites, including triterpenoid saponins and dencichine. PEVs were efficiently internalized by cardiomyocytes and preferentially accumulated in injured myocardium. Functionally, PEVs attenuated Dox-induced inflammation, apoptosis, myocardial atrophy, fibrosis, and cardiac dysfunction, with efficacy comparable to dexrazoxane. Mechanistically, transcriptomic and molecular analysis identified p53 as a central regulatory target. PEVs-derived metabolites targeted the p53 DNA-binding domain, suppressing p53 phosphorylation and transcriptional activation of pro-apoptotic and inflammatory genes. Notably, p53 activation attenuated PEVs-mediated protection, whereas p53 inhibition or silencing abolished additional protective effects, indicating a p53-dependent mechanism. PEVs protect against DIC by delivering bioactive metabolites to injured myocardium and inhibiting p53-driven oxidative, inflammatory, and apoptotic pathways, highlighting their potential as a phytomedicine-based cardioprotective strategy.\n --- END ACTUAL ABSTRACT FOR 42090956 ---\n\n- ERROR: You cited ID: 41875607 for the quote: \"IN BER-NE achieved a 3.2- and 3.6-fold increase in brain Cmax compared to BER-SUS IN and BER-NE IV.\"\n FACT: Strict Misquote Detected!

Despite its therapeutic potential in neurodegenerative disorders, including Parkinson's disease, cerebral ischemia, and epilepsy, its clinical translation in Alzheimer's disease (AD) is hindered by poor aqueous solubility, limited systemic bioavailability, and restricted blood-brain barrier (BBB) permeability. This study aimed to overcome these limitations by formulating a BER-loaded nanoemulsion (BER-NE) for intranasal (IN) delivery to achieve direct nose-to-brain (N2B) targeting. The optimized NE exhibited a droplet size of 138.5 \u00b1 0.96 nm and a polydispersity index (PDI) of 0.203 \u00b1 0.007, indicating a monodisperse system. The BER-NE demonstrated a drug content of 99.62 \u00b1 1.02%, confirming efficient drug incorporation. In vitro studies on SH-SY5Y neuroblastoma cells demonstrated that BER-NE reduced reactive oxygen species (ROS) levels by 2.09-fold and restored mitochondrial membrane potential (MMP) with a 3.61-fold increase in red/green fluorescence intensity compared to SCOP-induced cells. Further, pharmacokinetic (PK) profiling revealed that IN BER-NE achieved a 3.2- and 3.6-fold increase in brain Cmax compared to BER-SUS IN and BER-NE IV, respectively. The IN BER-NE demonstrated a 1.7- and 1.9-fold increase in %DTE and %DTP compared to the IN SUS, which supports the efficient N2B delivery. Behavioral assessments demonstrated dose-dependent reversal of SCOP-induced cognitive, depressive, and motor impairments. Additionally, treatment with HD BER-NE and MD BER-NE via the IN route markedly reduced the nitrite accumulation by 4.3- and 3.5-fold compared to the SCOP group, indicating attenuation of nitrosative stress. Collectively, these findings underscore the potential of IN BER-NE as a targeted and non-invasive therapeutic strategy for the management of AD.\n --- END ACTUAL ABSTRACT FOR 41875607 ---\n\n- ERROR: You cited ID: 41868129 for the quote: \"NST treatment may protect against cerebral ischemia/reperfusion injury by modulating lncRNA and mRNA expressions to enhance synaptic plasticity.\"\n FACT: Strict Misquote Detected!

This study aimed to investigate the mechanistic basis of NST using long noncoding RNA (lncRNA) and messenger RNA (mRNA) transcriptomics. The metabolites of NST were analyzed. Additionally, its systemically absorbed metabolites (in plasma) and brain-distributed metabolites were identified using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The therapeutic effects of NST were evaluated in a mouse model of middle cerebral artery occlusion (MCAO) using neurological scoring, behavioral testing, cerebral blood flow, and brain tissue staining. LncRNA and mRNA expression profiles were analyzed using the Agilent Mouse competing endogenous RNA microarray, followed by gene ontology and Kyoto encyclopedia of genes and genomes enrichment analyses. Differentially expressed transcripts were validated using quantitative reverse transcription polymerase chain reaction (qRT-PCR). UHPLC-MS/MS analysis detected 129 metabolites in NST; 33 metabolites in plasma; and 17 metabolites in brain tissue of rats administered with NST. NST treatment significantly reduced neurological deficit scores (Longa score), decreased beam-crossing latency, and increased forelimb grip strength in middle MCAO mice, indicating improved neurological function. Additionally, NST treatment enhanced cerebral blood flow recovery, ameliorated pathological damage, restored neuronal architecture, and increased Nissl-stained neuron density in peri-infarct brain tissue. NST also attenuated cellular apoptosis by upregulating Bcl-2 expression and downregulating Bax protein levels, exerting neuroprotective effects. Notably, NST treatment reversed 177 out of 5,378 differentially expressed IncRNAs and 52 out of 5,540 differentially expressed mRNAs that were dysregulated between the model and sham groups. These NST-modulated IncRNAs participate in key biological processes, including synaptic modulation, apoptosis regulation, and neuronal function. A synaptic plasticity-associated lncRNA-mRNA coexpression network was developed using NST-reversed transcripts. Validation using qRT-PCR confirmed the upregulation of NONMMUT050688.2 and NONMMUT044667.2, and the downregulation of NONMMUT092269.1 and NONMMUT101071.1, the downregulation of Nrn1, the upregulation of Grn, and the downward trend in Rasd2 expression in MCAO mice. All these alterations were reversed through NST treatment. In vivo experiments confirmed the efficacy of NST in ameliorating memory deficits, mitigating synaptic structural damage, and upregulating key synaptic protein expression (SYN and PSD95) in mice. NST may protect against cerebral ischemia/reperfusion injury by modulating lncRNA and mRNA expressions to enhance synaptic plasticity, thereby preserving neuronal structure and function.\n --- END ACTUAL ABSTRACT FOR 41868129 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"The blood-brain barrier (BBB) blocks most drugs from entering the brain.

Circular RNAs (circRNAs), characterized by their covalently bonded single-stranded loop configuration, have been identified as functional regulators across various cancer types. Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression.\n --- END ACTUAL ABSTRACT FOR 42568173 ---\n\n- ERROR: You cited ID: 42533576 for the quote: \"SmsG56S/Y males exhibit reduced body size, altered body composition, decreased locomotor and exploratory behaviors, and reduced seizure threshold, aligning with clinical features reported in SRS patients.\"\n FACT: Quote was found in context but NOT in the specific abstract mapped to ID '42533576'.\n \n Below is the complete, true text of ID 42533576 that you MUST read. \n Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n \n --- BEGIN ACTUAL ABSTRACT FOR 42533576 ---\n ID: 42533576\nTitle: Molecular mechanisms of the hypothalamus miR-27a/ PRKCA pathway in regulating neuronal function and aggression-related behavior.\nAbstract: The intensification of livestock production has heightened public concern about animal welfare, with aggressive behavior recognized as a key determinant of both welfare and productivity. MicroRNAs (miRNAs), which are critical post-transcriptional regulators, have emerged as important modulators of animal behavior. This study investigated the molecular basis of aggression in pigs ( Sus scrofa), focusing on miRNA-mediated regulation. Hypothalamic miRNA-sequencing of the most aggressive ( n=4) and least aggressive ( n=4) piglets identified nine differentially expressed miRNAs. Among these, miR-27a was significantly upregulated in aggressive individuals. Functional assays demonstrated that both porcine miR-27a and its human ( Homo sapiens) ortholog has-miR-27a-3p, suppressed autophagy, apoptosis, and neuronal plasticity in primary porcine neurons and human SH-SY5Y neuroblastoma cells. To clarify the underlying mechanisms, mRNA-sequencing was performed on porcine neurons transfected with miR-27a mimics or negative controls, identifying 436 differentially expressed genes (84 upregulated and 352 downregulated). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses highlighted eight genes- CBL, PRKCA, SLC38A1, ZBTB16, AANAT, CYP1A1, SLC7A11, and NTRK2-associated with tryptophan metabolism, oxidative stress, and long-term synaptic depression. Bioinformatic analysis and dual-luciferase reporter assays confirmed that miR-27a directly targets the 3'-UTR of PRKCA, thereby suppressing of autophagy, apoptosis, and neuronal plasticity.

Despite advances in antiseizure medications, effective epilepsy management remains challenging because of pharmacoresistance, limited blood-brain barrier (BBB) permeability, inadequate intracerebral drug accumulation, and systemic toxicity. Moreover, currently available therapies primarily provide symptomatic seizure control without addressing the fundamental pathological processes involved in epileptogenesis, neuroinflammation, oxidative stress, and neuronal degeneration. Intranasal administration has emerged as an attractive non-invasive approach for direct brain targeting, enabling therapeutic agents to circumvent BBB-associated transport barriers and access the central nervous system through the olfactory and trigeminal neural pathways. In this context, biodegradable nanomedicine platforms have gained considerable attention due to their favorable biocompatibility, controlled drug release, enhanced mucosal permeation, and potential for targeted intracerebral delivery. This review provides a comprehensive and critical overview of recent advances in intranasal biodegradable nanomedicine for epilepsy, integrating current knowledge on disease pathophysiology, biological and pharmaceutical barriers, nose-to-brain transport mechanisms, biodegradable nanoparticle platforms, and emerging functionalization strategies. Importantly, the review critically evaluates the current evidence, distinguishing encouraging preclinical findings and discusses the major translational challenges that continue to hinder clinical implementation. Finally, future perspectives are highlighted to identify opportunities for developing safer, more effective, and clinically translatable therapies for epilepsy management.\n --- END ACTUAL ABSTRACT FOR 42524508 ---\n\n- ERROR: You cited ID: 42511591 for the quote: \"We propose the concept of a \"Gasotransmitter Trio Network,\" emphasizing the molecular crosstalk among NO, CO, and H2S as a fundamental determinant of cellular homeostasis.\"\n FACT: Strict Misquote Detected!

However, accumulating evidence over the past several decades has established them as the three principal endogenous gasotransmitters that regulate a wide spectrum of physiological and pathological processes. Unlike conventional signaling molecules, gasotransmitters diffuse freely across biological membranes and exert potent biological effects through receptor-independent mechanisms, including redox-sensitive post-translational modifications and modulation of heme-containing proteins. Although the individual functions of NO, CO, and H2S have been extensively reviewed, emerging studies indicate that these gaseous mediators rarely operate in isolation. Instead, they form a highly integrated signaling network characterized by direct chemical interactions, reciprocal enzymatic regulation, and convergence upon common downstream pathways. In this mini-review, we propose the concept of a \"Gasotransmitter Trio Network,\" emphasizing the molecular crosstalk among NO, CO, and H2S as a fundamental determinant of cellular homeostasis. We first summarize the biosynthetic pathways and major signaling mechanisms of the gasotransmitter trio, including S-nitrosylation, persulfidation, and heme-dependent regulation. We then discuss recent advances revealing how interactions among these gases generate novel bioactive intermediates and coordinate redox signaling. Particular attention is given to the emerging roles of gasotransmitters in regulating ferroptosis, autophagy, and mitophagy by modulating iron metabolism, lipid peroxidation, mitochondrial quality control, and antioxidant defense systems. These findings support a unified framework in which gasotransmitters function as master regulators of cellular fate under conditions of physiological and pathological stress. Finally, we highlight recent progress in stimuli-responsive donors, CO-releasing molecules (CORMs), NO-releasing materials (NORMs), H2S donors, and advanced nanoplatforms that enable spatiotemporally controlled gas delivery. We propose that future therapeutic strategies will increasingly rely on programmable multi-gas systems that recapitulate endogenous gasotransmitter networks. Collectively, this review provides a systems-level perspective on gasotransmitter biology and outlines emerging opportunities for the development of precision gas medicine in cardiovascular, neurodegenerative, inflammatory, metabolic, and malignant diseases.\n --- END ACTUAL ABSTRACT FOR 42511591 ---\n\n- ERROR: You cited ID: 42594755 for the quote: \"Shikonin exerts anti-BCa activity, yet its direct molecular target and underlying mechanism remain undefined.\"\n FACT: Strict Misquote Detected!

Shikonin, a natural anti-tumor compound, exerts anti-BCa activity, yet its direct molecular target and underlying mechanism remain undefined. This study aimed to identify the direct target of shikonin in BCa and to elucidate the mechanism by which shikonin suppresses tumor progression. The anti-BCa effects of shikonin were assessed in vitro and in vivo. Drug affinity responsive target stability (DARTS) combined with 4D quantitative proteomics identified shikonin's direct target, which was validated by molecular docking and cellular thermal shift assay (CETSA). Gain- and loss-of-function experiments and ER-phagy-related assays elucidated the underlying molecular mechanism. Shikonin inhibited BCa cell proliferation, migration, invasion and induced senescence in vitro, and suppressed tumor growth in vivo with no obvious toxicity. Deoxyribonuclease 2 (DNASE2) was identified as shikonin's direct target; shikonin promoted DNASE2 ubiquitination and degradation without altering its mRNA level. DNASE2 was highly expressed in BCa and correlated with poor prognosis, and its knockdown mimicked and enhanced shikonin's anti-BCa effects. Mechanistically, shikonin targeted DNASE2 to downregulate Reticulon 3 (RTN3), thereby inhibiting RTN3-dependent endoplasmic reticulum autophagy (ER-phagy) in BCa. This study first identifies DNASE2 as the direct target of shikonin in BCa, and reveals that shikonin exerts anti-BCa activity by promoting DNASE2 ubiquitination/degradation to inhibit the DNASE2/RTN3 axis-mediated ER-phagy. The DNASE2/RTN3 axis is a novel ER-phagy regulatory node in BCa, providing a potential therapeutic target for BCa treatment.\n --- END ACTUAL ABSTRACT FOR 42594755 ---\n\n- ERROR: You cited ID: 42589605 for the quote: \"Of 4577 robustly targeted genes, a 1809-gene conserved \"pan-milk\" core showed the highest cross-species targeting and was enriched for transcriptional regulation.\"\n FACT: Strict Misquote Detected!

How the predicted regulatory potential of these miRNAs differs among the milks of different animals most relevant to human nutrition has not been systematically compared. Here, we performed an integrative in silico analysis of publicly available small-RNA sequencing data from 29 milk and milk-cell samples of human, cow, goat, and donkey origin. miRNAs were quantified against human (hsa) miRBase references-thereby restricting the analysis to evolutionarily conserved miRNAs with human orthologs-and their predicted effect on the human transcriptome was modeled by integrating predicted (mirDIP database) and experimentally supported (TarBase v9 database) miRNA-target interactions into a per-gene, per-species weighted targeting score. Because miRNAs act predominantly as repressors, this score is read as a prediction of which genes would be post-transcriptionally down-regulated in a recipient. miR-148a-3p dominated the exosomal spectrum of all four species (human, cow, goat, and donkey; \u224821.5% of pooled abundance), and the twenty most abundant miRNAs accounted for roughly three quarters of the signal. Of 4577 robustly targeted genes, a 1809-gene conserved \"pan-milk\" core showed the highest cross-species targeting and was enriched for transcriptional regulation, PI3K-Akt, MAPK, and TGF-\u03b2/SMAD signaling, autophagy and-strikingly-the components of the RNA-interference machinery itself. Species-restricted gene sets recapitulated biologically plausible programs, including a human-biased neuronal/axon-guidance and chromatin module, a donkey-biased transcriptional, epithelial, and immune (CD47) module, and a ruminant lipid/cholesterol and insulin-mTOR module. Across categories, we observed a reproducible confidence-exclusivity trade-off. We emphasize that these results are computational predictions that assume dietary miRNA uptake and do not constitute experimental validation. We provide the complete targetome as a hypothesis-generating resource to prioritize candidate genes, pathways, and milk types for future functional, nutritional, and epigenetic investigation. Across the 29 samples from the four species, miRNA composition segregated by species (silhouette width = 0.82, a cluster-separation measure ranging from -1 to 1, with values near 1 indicating well-separated groups) and the category structure exceeded a permutation null, indicating that the between-species signal is robust to differences in dataset origin and milk state.\n --- END ACTUAL ABSTRACT FOR 42589605 ---\n\n- ERROR: You cited ID: 42589242 for the quote: \"PERK silencing was accompanied by activation of apoptosis-related genes and proteins-BCL2-associated X (Bax), caspase-3, C/EBP homologous protein (CHOP).\"\n FACT: Strict Misquote Detected!

On the other hand, excessive and prolonged ER stress leads to apoptosis. However, the relationships between different UPR branches and apoptosis or autophagy vary in cancer cells of different origins and depend on the extent and nature of the stress signal. This study was designed to establish the role of ER stress sensors protein kinase RNA-like endoplasmic reticulum kinase (PERK) and inositol-requiring enzyme 1 (IRE1\u03b1) in apoptosis or autophagy signaling in T-lymphoblastic leukemia MOLT-3 cells via the RNA interference method. The cells were transfected with small interfering RNAs (si-PERK, si-IRE1\u03b1, or si-Cont) for 6 h and further cultured under normal conditions for 72 h to provide an insight into chronic effects of the gene silencing. The expression of apoptosis and autophagy effectors at the mRNA and protein levels was compared using RT-PCR and Western blot assays, respectively. Transfection of the cells with PERK siRNA led to a significant decrease in PERK protein and gene expression, and decreased phosphorylation of its downstream effector eukaryotic initiation factor 2\u03b1 (eIF2\u03b1). PERK silencing was accompanied by activation of apoptosis-related genes and proteins-BCL2-associated X (Bax), caspase-3, C/EBP homologous protein (CHOP), while the levels of autophagy markers (Unc-51 like autophagy activating kinase 1 (ULK1), Beclin-1, and microtubule-associated proteins 1A/1B light chain 3 (LC3A/B)) remained stable. In contrast, treatment of the cells with si-IRE1\u03b1 reduced the content of IRE1\u03b1, X-box-binding protein 1 (sXBP1), and glucose-regulated protein 78 (GRP78) proteins, but increased ERN1 gene expression. IRE1\u03b1 RNA interference did not affect the levels of the pro-apoptotic marker Bax, but suppressed caspase-3, CHOP, c-Jun N-terminal kinase (JNK), and autophagy signaling molecules (ULK1, Beclin-1, LC3A/B) at both the transcriptional and translational levels. These results indicate that the PERK pathway is an important contributor to the survival of MOLT-3 cells under basal ER stress, while PERK depletion compromises the resistance of cells to UPR-mediated apoptosis. The IRE1\u03b1 UPR branch is directly linked with autophagy-dependent signaling, although IRE1\u03b1 knockdown exerted a more complicated influence on the cells, probably via activation of multiple pro-death and compensatory pro-survival regulatory mechanisms.\n --- END ACTUAL ABSTRACT FOR 42589242 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"The blood-brain barrier (BBB) blocks most drugs from entering the brain.

"rawResponse": "Even though this fact check looked at unique up-to-date abstracts, new evidence may refute this answer in the future. Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. 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]\nHypothesis: Intranasal delivery of Spermidine-modified Ginseng Extracellular Vesicles (S-GEVs) loaded with GRN mRNA exploits the cribriform plate anatomy to bypass the blood-brain barrier, providing a neuro-targeted delivery system for progranulin gene therapy that acts synergistically with spermidine-induced autophagy to suppress pathological TMEM106B amyloid accumulation and restore endolysosomal homeostasis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe proposed hypothesis posits that a composite nanotherapeutic consisting of ginseng-derived extracellular vesicles (GEVs) functionalized with spermidine and loaded with *GRN* mRNA could ameliorate neurodegenerative conditions characterized by *GRN* haploinsufficiency and TMEM106B protein aggregation. The conceptual framework relies on three intersecting domains: (1) nasal-to-brain delivery mechanisms circumventing the blood-brain barrier (BBB), (2) the intrinsic neuroprotective and autophagy-inducing properties of spermidine, and (3) the endolysosomal roles of PGRN and TMEM106B. While the evidence validates these individual components, the specific synergy of an S-GEV/GRN mRNA delivery system remains a novel, untested computational framework.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent evidence confirms that the blood-brain barrier (BBB) presents a formidable obstacle to neurotherapeutics, with \"over 98% of small-molecule drugs and nearly all biologics fail to cross this barrier.\" Intranasal delivery offers a non-invasive bypass, as identified by the presence of \"a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations\" which facilitate drainage to the cervical lymph nodes. Ginseng-derived exosomes have been characterized as \"natural nanovesicles\" offering \"large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers.\" \n\nRegarding the therapeutic cargo, *GRN* mutations and TMEM106B aggregation are central to neurodegeneration, as \"The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases.\" Furthermore, \"Recent new studies reported that TMEM106B proteins form intracellular amyloid filaments which universally exist in various neurodegenerative diseases, sometimes being the dominant form of protein aggregation.\" Restoration of progranulin is hypothesized to alleviate lysosomal dysfunction. Concurrent induction of autophagy is essential, as \"Spermidine, a naturally occurring polyamine, has emerged as a candidate modulator of brain aging because it regulates autophagy, mitochondrial function, oxidative balance, and neuroinflammatory signaling.\" The integration of these elements into a single S-GEV platform represents a sophisticated, if currently unverified, therapeutic modality.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* TMEM106B aggregation is not merely a loss-of-function event but involves the formation of universal intracellular amyloid filaments across multiple neurodegenerative diseases.\n* Nasal delivery routes, specifically through arachnoid fenestrations at the olfactory bulb, are increasingly recognized as viable channels for protein and nucleic acid transport.\n* Ginseng-derived exosomes are effectively serving as \"natural nanocarriers\" capable of cross-kingdom delivery of metabolites and therapeutics.\n* Spermidine's efficacy as a neuroprotector is dosage-dependent, where \"low doses has the potential to be a general-purpose neuroprotector.\"\n* Autophagic flux, regulated by proteins such as Beclin-1 and the mTOR/AMPK axis, is a critical regulatory node for both progranulin and TMEM106B-associated pathologies.\n* The TMEM106B/progranulin endolysosomal-lipid axis is essential for metabolic homeostasis; its disruption leads to protein accumulation.\n* Emerging \"Gasotransmitter Trio Networks\" (NO, CO, H2S) modulate autophagy and mitophagy alongside the protein-based pathways of *GRN* and TMEM106B.\n* Recent proteomics studies confirm that CLK4 regulates autophagy-related proteins (e.g., SQSTM1) in cancer and degenerative models, highlighting broader splicing/autophagy interactions.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"33796852": "ID: 33796852\nTitle: Fronto-temporal dementia risk gene TMEM106B has opposing effects in different lysosomal storage disorders.\nAbstract: TMEM106B is a transmembrane protein localized to the endo-lysosomal compartment. Genome-wide association studies have identified TMEM106B as a risk modifier of Alzheimer's disease and frontotemporal lobar degeneration, especially with progranulin haploinsufficiency. We recently demonstrated that TMEM106B loss rescues progranulin null mouse phenotypes including lysosomal enzyme dysregulation, neurodegeneration and behavioural alterations. However, the reason whether TMEM106B is involved in other neurodegenerative lysosomal diseases is unknown. Here, we evaluate the potential role of TMEM106B in modifying the progression of lysosomal storage disorders using progranulin-independent models of Gaucher disease and neuronal ceroid lipofuscinosis. To study Gaucher disease, we employ a pharmacological approach using the inhibitor conduritol B epoxide in wild-type and hypomorphic Tmem106b-/- mice. TMEM106B depletion ameliorates neuronal degeneration and some behavioural abnormalities in the pharmacological model of Gaucher disease, similar to its effect on certain progranulin null phenotypes. In order to examine the role of TMEM106B in neuronal ceroid lipofuscinosis, we crossbred Tmem106b-/- mice with Ppt1-/-, a genetic model of the disease. In contrast to its conduritol B epoxide-rescuing effect, TMEM106B loss exacerbates Purkinje cell degeneration and motor deficits in Ppt1-/- mice. Mechanistically, TMEM106B is known to interact with subunits of the vacuolar ATPase and influence lysosomal acidification. In the pharmacological Gaucher disease model, the acidified lysosomal compartment is enhanced and TMEM106B loss rescues in vivo phenotypes. In contrast, gene-edited neuronal loss of Ppt1 causes a reduction in vacuolar ATPase levels and impairment of the acidified lysosomal compartment, and TMEM106B deletion exacerbates the mouse Ppt1-/- phenotype. Our findings indicate that TMEM106B differentially modulates the progression of the lysosomal storage disorders Gaucher disease and neuronal ceroid lipofuscinosis. The effect of TMEM106B in neurodegeneration varies depending on vacuolar ATPase state and modulation of lysosomal pH. These data suggest TMEM106B as a target for correcting lysosomal pH alterations, and in particular for therapeutic intervention in Gaucher disease and neuronal ceroid lipofuscinosis.",

However, the limited neural differentiation of BMSCs remains a big challenge to overcome. Herein, for the first time, ginseng-derived exosomes (G-Exos) were demonstrated to have excellent efficiency in stimulating the neural differentiation of BMSCs by transferring the incorporated miRNAs to BMSCs efficiently. In vivo, a photo-cross-linkable hydrogel with chemokine and G-Exos loaded shows strong efficacy in recruiting and directing the neural differentiation of BMSCs in the program. G-Exos were demonstrated to be promising nanoplatforms in transferring plant-derived miRNAs to mammalian stem cells for neural differentiation both in vitro and in vivo, possessing great potential in neural regenerative medicine.",

In this study, we investigated extracellular vesicles (EVs) and neurotrophic factors in the cerebrospinal fluid (CSF) of 120 subjects: 36 with AD, 30 with DLB, 34 with FTD and 20 controls. Specifically, CSF EVs were analyzed by Nanoparticle Tracking Analysis and neurotrophic factors were measured with ELISA. We found higher EV concentration and lower EV size in AD and DLB groups compared to the controls. Classification tree analysis demonstrated EV size as the best parameter able to discriminate the patients from the controls (96.7% vs. 3.3%, respectively). The diagnostic performance of the EV concentration/size ratio resulted in a fair discrimination level with an area under the curve of 0.74. Moreover, the EV concentration/size ratio was associated with the p-Tau181/A\u03b242 ratio in AD patients. In addition, we described altered levels of cystatin C and progranulin in the DLB and AD groups. We did not find any correlation between neurotrophic factors and EV parameters. In conclusion, the results of this study suggest a common involvement of the endosomal pathway in neurodegenerative dementias, giving important insight into the molecular mechanisms underlying these pathologies.",
"37519873": "ID: 37519873\nTitle: Transcranial application of magnetic pulses for improving brain drug delivery efficiency via intranasal injection of magnetic nanoparticles.\nAbstract: As the blood-brain barrier (BBB) hinders efficient drug delivery to the brain, drug delivery via the intranasal pathway, bypassing the BBB, has received considerable attention. However, intranasal administration still has anatomical and physiological limitations, necessitating further solutions to enhance effectiveness. In this study, we used transcranial magnetic stimulation (TMS) on fluorescent magnetic nanoparticles (MNPs) of different sizes (50, 100, and 300 nm) to facilitate MNP's transportation and delivery to the brain parenchyma. To validate this concept, anesthetized rats were intranasally injected with the MNPs, and TMS was applied to the center of the head. As the result, a two-fold increase in brain MNP delivery was achieved using TMS compared with passive intranasal administration. In addition, histological analysis that was performed to investigate the safety revealed no gross or microscopic damages to major organs caused by the nanoparticles. While future studies should establish the delivery conditions in humans, we expect an easy clinical translation in terms of device safety, similar to the use of conventional TMS. The strategy reported herein is the first critical step towards effective drug transportation to the brain.",

However, in the treatment of glioma, effective nanomedicine has limited access to the brain because of the blood-brain barrier (BBB). Previously, we demonstrated nano-sized ginseng-derived exosome-like nanoparticles (GENs) consisting of phospholipids including various bioactive components, and evaluated anti-tumor immune responses in T cells and Tregs to inhibit tumor progression. It was found that the enhanced targeting ability of GENs to the BBB and glioma induced a significant therapeutic effect and exhibited strong efficacy in recruiting M1 macrophage expression in the TME. GENs were demonstrated to be successful candidates in glioma therapeutics both in vitro and in vivo, suggesting excellent potential for inhibiting glioma progression and regulating tumor-associated macrophages (TAMs).",
"37563705": "ID: 37563705\nTitle: TMEM106B aggregation in neurodegenerative diseases: linking genetics to function.\nAbstract: Mutations of the gene TMEM106B are risk factors for diverse neurodegenerative diseases. Previous understanding of the underlying mechanism focused on the impairment of lysosome biogenesis caused by TMEM106B loss-of-function. However, mutations in TMEM106B increase its expression level, thus the molecular process linking these mutations to the apparent disruption in TMEM106B function remains mysterious. Recent new studies reported that TMEM106B proteins form intracellular amyloid filaments which universally exist in various neurodegenerative diseases, sometimes being the dominant form of protein aggregation. In light of these new findings, in this review we systematically examined previous efforts in understanding the function of TMEM106B in physiological and pathological conditions. We propose that TMEM106B aggregations could recruit normal TMEM106B proteins and interfere with their function. TMEM106B mutations could lead to lysosome dysfunction by promoting the aggregation of TMEM106B and reducing these aggregations may restore lysosomal function, providing a potential therapeutic target for various neurodegenerative diseases.",
"37720571": "ID: 37720571\nTitle: Amelioration of colitis progression by ginseng-derived exosome-like nanoparticles through suppression of inflammatory cytokines.\nAbstract: Damage to the healthy intestinal epithelial layer and regulation of the intestinal immune system, closely interrelated, are considered pivotal parts of the curative treatment for inflammatory bowel disease (IBD). Plant-based diets and phytochemicals can support the immune microenvironment in the intestinal epithelial barrier for a balanced immune system by improving the intestinal microecological balance and may have therapeutic potential in colitis. However, there have been only a few reports on the therapeutic potential of plant-derived exosome-like nanoparticles (PENs) and the underlying mechanism in colitis. This study aimed to assess the therapeutic effect of PENs from Panax ginseng, ginseng-derived exosome-like nanoparticles (GENs), in a mouse model of IBD, with a focus on the intestinal immune microenvironment. To evaluate the anti-inflammatory effect of GENs on acute colitis, we treated GENs in Caco2 and lipopolysaccharide (LPS) -induced RAW 264.7 macrophages and analyzed the gene expression of pro-inflammatory cytokines and anti-inflammatory cytokines such as TNF-\u03b1, IL-6, and IL-10 by real-time PCR (RT-PCR). Furthermore, we further examined bacterial DNA from feces and determined the alteration of gut microbiota composition in DSS-induced colitis mice after administration of GENs through 16S rRNA gene sequencing analysis. GENs with low toxicity showed a long-lasting intestinal retention effect for 48 h, which could lead to effective suppression of pro-inflammatory cytokines such as TNF-\u03b1 and IL-6 production through inhibition of NF-\u03baB in DSS-induced colitis. As a result, it showed longer colon length and suppressed thickening of the colon wall in the mice treated with GENs. Due to the amelioration of the progression of DSS-induced colitis with GENs treatment, the prolonged survival rate was observed for 17 days compared to 9 days in the PBS-treated group. In the gut microbiota analysis, the ratio of Firmicutes/Bacteroidota was decreased, which means GENs have therapeutic effectiveness against IBD. Ingesting GENs would be expected to slow colitis progression, strengthen the gut microbiota, and maintain gut homeostasis by preventing bacterial dysbiosis. GENs have a therapeutic effect on colitis through modulation of the intestinal microbiota and immune microenvironment. GENs not only ameliorate the inflammation in the damaged intestine by downregulating pro-inflammatory cytokines but also help balance the microbiota on the intestinal barrier and thereby improve the digestive system.",
"38132480": "ID: 38132480\nTitle: Improvement in Yield of Extracellular Vesicles Derived from Edelweiss Callus Treated with LED Light and Enhancement of Skin Anti-Aging Indicators.\nAbstract: The process of skin aging is currently recognized as a disease, and extracellular vesicles (EVs) are being used to care for it. While various EVs are present in the market, there is a growing need for research on improving skin conditions through microbial and plant-derived EVs. Edelweiss is a medicinal plant and is currently an endangered species. Callus culture is a method used to protect rare medicinal plants, and recently, research on EVs using callus culture has been underway. In this study, the researchers used LED light to increase the productivity of Edelweiss EVs and confirmed that productivity was enhanced by LED exposure. Additionally, improvements in skin anti-aging indicators were observed. Notably, M-LED significantly elevated callus fresh and dry weight, with a DW/FW ratio of 4.11%, indicating enhanced proliferation. Furthermore, M-LED boosted secondary metabolite production, including a 20% increase in total flavonoids and phenolics. The study explores the influence of M-LED on EV production, revealing a 2.6-fold increase in concentration compared to darkness. This effect is consistent across different plant species (Centella asiatica, Panax ginseng), demonstrating the universality of the phenomenon. M-LED-treated EVs exhibit a concentration-dependent inhibition of reactive oxygen species (ROS) production, surpassing dark-cultured EVs. Extracellular melanin content analysis reveals M-LED-cultured EVs' efficacy in reducing melanin production. Additionally, the expression of key skin proteins (FLG, AQP3, COL1) is significantly higher in fibroblasts treated with M-LED-cultured EVs. These results are expected to provide valuable insights into research on improving the productivity of plant-derived EVs and enhancing skin treatment using plant-derived EVs.",
"39411956": "ID: 39411956\nTitle: To Explore Nasal-Brain Lymphatic System for Brain-Targeted Drug Delivery and to Treat Neurodegenerative Diseases.\nAbstract: Brain-related Neurodegenerative Disorders (NDD) are the leading cause of low life expectancy globally. Brain-targeted drug delivery is required for treating most the NDD via bypassing the blood-brain barrier, and hepatic first-pass metabolism. The nasal-brain drug delivery route has the advantage of locally enhancing drug delivery to the brain, mainly through the olfactory route rather than systemic circulation. To overcome the limitations of nasal-brain drug delivery, a nanocarrier approach and mucoadhesive polymers are needed. Notwithstanding these constraints, various nanotechnology techniques have been created, including polymeric micelles, liposomes, polymeric nanoparticles, solid lipid nanoparticles, & nano-emulsions. This review aims to explore the intranasal pathway for drug delivery through the nasal-brain lymphatic systems, considering brain anatomy and physiology along with a drug formulation design approach.",
"39587576": "ID: 39587576\nTitle: Chinese herbal medicine-derived extracellular vesicles as novel biotherapeutic tools: present and future.\nAbstract: Extracellular vesicles (EVs) are phospholipid bilayer-enclosed biological particles that are secreted by almost all living cells including animals, plants, and microorganisms. Chinese herbal medicines (CHM) have a long history of using plant-based remedies to treat and prevent human diseases. Chinese herbal medicine-derived extracellular vesicle (CHMEV) generic term refers to nanoscale membrane structures isolated from medicinal plants such as ginseng, ginger, and Panax notoginseng. In recent years, CHMEVs have garnered substantial attention as a novel class of functional components due to their high bioavailability, safety, easy accessibility, and diverse therapeutic effects, indicating their great potential for development as a new dosage form of CHM. Research on CHMEVs in traditional Chinese medicine (TCM) has become a prominent area of interest, opening new avenues for further exploration into the therapeutic effects and functional mechanisms of CHM. Nonetheless, as an emerging field, there is much unknown about these vesicles, and current research remains inconsistent. The review comprehensively summarizes the biogenesis, isolation methods, and physical, and biochemical characterizations of CHMEVs. Additionally, we highlight their biomedical applications as therapeutic agents and drug delivery carriers, including anti-inflammatory, anticancer, regenerative, and antiaging activities. Finally, we propose current challenges and future perspectives. By summarizing the existing literature, we aim to offer valuable clues and inspiration for future CHMEV research, thereby facilitating research standardization of CHMEVs in the treatment of human diseases and drug discovery.",
"39740230": "ID: 39740230\nTitle: The Cardioprotective Effect of Ginseng Derived Exosomes via Inhibition of Oxidative Stress and Apoptosis.\nAbstract: Ginsenosides possess potential protective effects against cisplatin (CDDP)-induced toxicity, but the limited bioavailability of ginsenosides hampered their therapeutic application. Ginseng exosomes (G-Exo), which are active ingredients in ginseng, exhibit excellent biocompatibility and low immunogenicity. Here, G-Exo were isolated from ginseng roots through a combination of ultracentrifugation and sucrose gradient centrifugation techniques. Subsequently, the potential protective effect of G-Exo on CDDP induced cardiotoxicity, and its underlying mechanisms were explored. The findings demonstrated that G-Exo effectively mitigated CDDP-induced oxidative stress and apoptosis in vitro. Moreover, in vivo experiments revealed that G-Exo significantly inhibited the increases in serum cardiac troponin T (cTnT), creatine kinase (CK), and lactate dehydrogenase (LDH) levels in mice induced by CDDP. Histological assessment and tissue staining further corroborated that G-Exo alleviated the cardiac tissue damage and apoptosis caused by CDDP. Mechanistically, G-Exo were found to alleviate CDDP-induced apoptosis through blocking the MAPK signaling. Collectively, these results suggest that G-Exo hold the potential to mitigate cisplatin-induced cardiac injury by regulating the MAPK pathway, thereby highlighting the therapeutic potential of G-Exo as a protective agent against CDDP-induced cardiotoxicity.",

However, concerns exist regarding potential toxicity and cost-effectiveness, limiting their clinical applications. In contrast, plant-derived exosomes (PDEs), as natural nanovesicles, offer significant advantages as drug delivery carriers due to their large-scale production, biocompatibility, and ability to efficiently transport therapeutic drug across cellular barriers. In this work, we established a ginseng-derived exosome (G-Exo)-based CDDP delivery system (G-CDDP) and evaluated its anti-tumor efficacy both in vitro and in vivo. The results demonstrated that G-CDDP effectively targeted tumor site, inhibiting the proliferation and migration and promoting apoptosis in U-87MG tumor cells. Notably, the amount of CDDP in G-CDDP required for achieving the same cytotoxic effect on tumor cells was 12.66 times lower than that of free CDDP. In U-87MG tumor-bearing mice, G-CDDP effectively targeted tumor sites and exhibited significant therapeutic effect. Collectively, these findings highlight the potent anti-tumor activity of G-CDDP at reduced CDDP dosage, positioning it as a promising and efficient alternative to conventional drug treatments in clinical settings.",
"40395512": "ID: 40395512\nTitle: TDP-43 Secretion via Extracellular Vesicles Is Regulated by Macroautophagy.\nAbstract: The pathological accumulation of the nuclear protein TDP-43 (TAR DNA-binding protein 43 kDa) in the cytoplasm is characteristic of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD-TDP), and its spread through the brain and spinal cord is closely associated with the progression of these two diseases. However, the mechanisms through which the TDP-43 pathology propagates throughout the central nervous system remain unclear. We recently reported the role of (macro)autophagy in the secretion of TDP-43 via extracellular vesicles (EVs). We found that among the autophagy modulators, bafilomycin A1 (Baf) and GRN (granulin precursor) deficiency impair the formation of autolysosomes and promote the secretion of TDP-43 by EVs. TDP-43 loading on EVs involves autophagy-related proteins and the knockdown of TDP-43 augmented Baf-induced EV release. Thus, our results suggest that the loss-of-function of TDP-43 accelerates release of EVs possibly derived from autophagosomes, which may mediate cell-to-cell spread of the TDP-43 pathology.",

Current treatment approaches are hindered by limited efficacy, poor patient adherence, and the inability of many therapeutic agents to effectively penetrate the blood-brain barrier (BBB). The BBB, a selective and protective interface between the bloodstream and brain tissue, restricts drug delivery to the central nervous system (CNS), resulting in suboptimal concentrations of antidepressants at the target site and delayed therapeutic responses. This review explores the limitations of conventional drug delivery systems for depression and highlights the intranasal route as a promising non-invasive alternative for direct brain targeting. Intranasal delivery bypasses hepatic first-pass metabolism and systemic degradation, offering rapid drug absorption and CNS access through olfactory and trigeminal neural pathways. Among emerging strategies, nanotherapeutics have gained increasing attention due to their capacity to improve solubility, protect labile compounds, and provide sustained drug release. Nanoparticles can encapsulate both hydrophilic and lipophilic drugs, enhancing their pharmacokinetics and stability. When administered intranasally, these nanocarriers can directly reach the brain, potentially reducing dosage frequency and enhancing therapeutic outcomes, while minimizing systemic side effects. This review focuses on the latest advancements in intranasal nanotherapeutic formulations for depression, such as polymeric nanoparticles, nanoemulsions, solid lipid nanoparticles, and nanostructured lipid carriers. The synergistic integration of nanotechnology and targeted CNS delivery offers a transformative approach to overcome the challenges posed by the BBB and improve depression management. While preclinical findings are promising, further clinical studies are necessary to confirm safety, efficacy, and long-term outcomes. Overall, intranasal nanotherapeutics represent a compelling direction for the development of next-generation antidepressant therapies, aiming to achieve faster onset, improved adherence, and enhanced quality of life for patients suffering from depression.",

Effective antimicrobial and anti-inflammatory therapies are essential to facilitate wound recovery. Herein, we introduce a highly biocompatible, ROS-responsive DNA hydrogel (LGAH), modified with aggregation-induced emission luminogens (AIEgen) and incorporating ginseng-derived exosomes (G-Exos) and nitric oxide (NO) donor-L-arginine (L-Arg) to promote healing of infected wounds. The hydrogel degrades in response to elevated ROS levels, releasing therapeutic agents. Upon laser irradiation, AIEgen generates 1O2, which activates L-Arg to produce NO, leading to a synergistic antimicrobial effect. NO is particularly effective at inhibiting bacterial growth and promoting angiogenesis, supporting wound healing. G-Exos modulate immune responses, reduce inflammation, and promote the transition from the inflammatory to the proliferative phase. They also enhance cell proliferation, migration, and collagen production, which are key to tissue regeneration. In vivo experiments demonstrated that LGAH significantly accelerates S. aureus-infected wound healing by modulating the wound microenvironment and promoting tissue regeneration. Transcriptomic analysis revealed that LGAH down-regulates gene expression in inflammation and immune response signaling pathways while up-regulating genes related to energy metabolism. Biosafety evaluations at cellular and animal levels have demonstrated that LGAH possesses excellent biocompatibility and biodegradability, making it ideal for tissue repair and regeneration. This multifunctional DNA hydrogel system offers a safe and promising strategy for the clinical treatment of infected wounds.",

Two patients were included in the study: a 32-year-old woman with scattered PIH on her forehead, cheeks, nose, and perioral area, and a 37-year-old man with hyperpigmentation on both cheeks. Both patients underwent 3 sessions of MTS spaced 3 weeks apart, followed by the immediate application of a topical exosome (P198 RECORE SB PLUS, P198 ExoNature, Primoris International Co., Ltd., Seoul, Republic of Korea). PIH severity was assessed using the PIH severity scale, with baseline scores of grade 2 (mild) for both patients. One month after the final session, posttreatment scores improved to grade 1 (trace) for both patients, as evaluated by 2 dermatologists. Both patients demonstrated significant improvements in hyperpigmentation and overall skin tone. The female patient achieved a more even complexion with visible lightening in affected areas, whereas the male patient experienced a marked reduction in cheek pigmentation. Both patients expressed high satisfaction with the results, and no adverse effects were reported. These findings suggest that the combination of MTS and topical exosomes is a promising, safe approach for managing PIH, particularly in individuals with darker skin types prone to pigmentation disorders.",

Despite this commonality, most current therapeutic approaches in the field, such as anti-aggregate antibodies, are focused on individual diseases or single neuropathologies with only limited success. The endolysosomal proteins progranulin and TMEM106B were both initially associated with frontotemporal lobar degeneration but have subsequently also been linked to other neurodegenerative diseases. Thus, these proteins are predicted to participate in common pathogenic pathways shared across various neurodegenerative diseases. Importantly, recent discoveries of TMEM106B amyloid fibrils in varied neurodegenerative diseases and glycosphingolipid regulation by progranulin and TMEM106B further support their central roles in cross-disease neurodegenerative mechanisms. This review summarizes recent advances in progranulin and TMEM106B function within the endolysosomal system and neurodegenerative diseases. It describes preclinical models and therapeutic approaches for progranulin- and TMEM106B-associated diseases.

While PD-1/PD-L1 immune checkpoint blockade has shown promise, its efficacy is often limited by tumor-induced immune evasion. Ginseng-derived exosomes (G-Exos), as natural plant-based nanocarriers, may offer a novel strategy for immunomodulation. This study investigated the potential of G-Exos to regulate PD-L1 expression and enhance anti-tumor immunity in NSCLC. Exosomes were isolated from ginseng cell cultures and characterized via transmission electron microscopy and nanoparticle tracking analysis. Uptake by NSCLC cells was confirmed using PKH26 labeling. In vitro, NSCLC cells were co-cultured with activated T cells to evaluate cytotoxicity (colony formation), cytokine secretion [enzyme-linked immunosorbent assay (ELISA)], and T-cell activation (flow cytometry). PD-L1 expression was assessed by quantitative polymerase chain reaction (qPCR) and Western blot. In vivo, C57BL/6 mice (n = 20) bearing Lewis lung carcinoma (LLC) tumors were randomized into four groups (n = 5/group): PBS, G-Exos (10\u00a0\u03bcg), anti-PD-L1 (8\u00a0\u03bcg), or combination therapy. Treatments were administered intravenously every other day for 20 days. Tumor growth was measured, and tissues were analyzed by immunohistochemistry and flow cytometry. G-Exos were efficiently internalized by NSCLC cells and demonstrated immunostimulatory properties in vitro. They enhanced T-cell-mediated cytotoxicity, as reflected by reduced tumor colony formation, and promoted immune activation, evidenced by increased IL-2 and IFN-\u03b3 secretion and a higher proportion of CD8\u207a T cells expressing TNF-\u03b1 and perforin. Mechanistically, G-Exos downregulated PD-L1 expression at both transcriptional and translational levels in NSCLC cells. In vivo, G-Exos treatment significantly inhibited tumor growth and, when combined with anti-PD-L1 monoclonal antibody, exhibited a synergistic effect characterized by greater tumor suppression and increased infiltration of cytotoxic CD8\u207a T cells in the tumor microenvironment. Ginseng-derived exosomes downregulate PD-L1 and enhance T-cell function, counteracting immune evasion in NSCLC. Their synergy with anti-PD-L1 therapy supports their potential as adjuvant nanotherapeutics in cancer immunotherapy.",

Despite their widespread prevalence, effective treatment options remain inadequate. A significant challenge contributing to this therapeutic gap is the impermeability of the blood-brain barrier to many drugs. Thus, developing new strategies to bypass this barrier and deliver therapeutic agents to the central nervous system (CNS) is crucial. The intranasal (IN) route has emerged as a promising approach in animal models of neurodegenerative diseases. This method of administration is gaining attention as a viable alternative for delivering various pharmacological agents, including proteins, miRNA, and oligonucleotides, to the CNS. It offers advantages over oral and intravenous routes. However, translating IN formulations from preclinical models to clinical practice presents several challenges. Assessing the adequacy of current clinical trials in evaluating IN delivery efficacy is crucial. Furthermore, the introduction of novel formulations such as nanoparticles sparks excitement for enhancing the effectiveness of IN drug administration compared to traditional free drug solutions. This review summarizes recent advancements in delivering therapeutic molecules to the CNS to treat neurodegenerative diseases. We explore critical strategies to overcome the blood-brain barrier obstacle, focusing on recent progress using the IN route as a potential avenue for effective neurodegenerative disease therapies. Additionally, we will delve into the preclinical studies that have provided the basis for the clinical trials conducted.",

However, the investigation on ginseng-derived exosomes is still in the initial stage. This study developed a photonic crystal-based Bragg scattering coupling electrochemiluminescence (BSC-ECL) biosensor for detection of miRNA396a-3p in exosome-like nanoparticles (GENs) and ginseng exosomes (Gexos). First, copper nanoclusters were engineered into Cu superparticles with \u03c0-\u03c0 stacking of 2,6-dimethylbenzenethiol ligands via a ligand-mediated self-assembly strategy. The prepared Cu superparticles with significantly enhanced luminescence intensity and stability can be used as a nanoprobe. Furthermore, the Bragg scattering law was utilized to modulate the ECL intensity of the Cu superparticles. Due to the highly periodic structure of MIL-96-based photonic crystals, multiple scattering pathways in photonic crystals greatly increased the effective photon flux of Cu superparticles, thus creating a positive feedback loop between photon absorption and emission. Therefore, this cascade amplification mechanism ultimately led to significant BSC-ECL enhancement. The BSC-ECL provided a new quantitative analysis method for key miRNA detection in plant extracellular vesicles, which revealed distinct miRNA concentrations in GENs and Gexos. The method also demonstrated considerable potential in areas such as ginseng quality control, product development, and bioanalysis applications.",

Traditional treatment methods have limited effects, including being eliminated in the moist and dynamic environment of the mouth, and are prone to various side effects or the development of drug resistance. In this study, we designed borate ester-based and Schiff base-cross-linked hydrogel (OPEC), and loaded ginseng-derived exosome (GEX@OPEC) for the treatment of OU. OPEC hydrogel is composed of phenylboronic acid-functionalized hyaluronic acid oxide (OHA-PBA), epigallocatechin gallate (EGCG), and carboxymethyl chitosan (CMCS). The addition of EGCG enhances its borate cross-linking network and improves the adhesion of the hydrogel. GEX is connected to OPEC through hydrogen bonds and loaded into the hydrogel, further enhancing its gel network. GEX@OPEC exhibited excellent biocompatibility and degradability, ensuring safe oral use of the hydrogel. GEX@OPEC can release EGCG and GEX in response to pH and ROS to exert therapeutic effects. Our research results showed that GEX@OPEC had excellent antibacterial properties, anti-inflammatory and antioxidant stress effects, as well as angiogenic properties, which can effectively promote the healing of OU in diabetic rat models simulating OU. To sum up, GEX@OPEC has good application prospects in the treatment of diabetic OU.",

Different neurodegenerative disorders such as Huntington's disease, Alzheimer's disease, Parkinson's disease, amyotrophic, Lewy body disease can be treated by curcumin, which is a strong antioxidant polyphenol with neuroprotective and anti-amyloid properties. However, Blood-brain barrier (BBB) and blood cerebrospinal fluid barrier restricts the permeation of curcumin to the brain leads poor distribution of the drug in brain tissue. The intranasal pathway holds promise for enhancing the treatment of CNS disorders since it bypasses the BBB and increases the brain bioavailability of drug. As nanotechnology continues to improve, research on the delivery of drug through intranasal route has grown significantly in last 10 years. Several nanocarriers have been developed such as nano-emulsions, microspheres, dendrimers, liposomes, carbon-based nanoformulation, and nanoparticles to deliver curcumin to the brain via intranasal route for the treatment of neurodegenerative diseases.

Excessive inflammatory responses, oxidative stress, and cell death are key mechanisms underlying IRI. The lack of multi-targeted therapies contributes to the current insufficiency in clinical IRI management. This study developed endothelial-targeting VHPKQHR peptide (VHP)-modified ginseng-derived exosomes (G-Exos) loaded with IL-6 small interfering RNA (Si-IL6) (siRNA@VG-Exos) to mitigate liver IRI. VHP modification facilitated the targeted delivery of siRNA@VG-Exos to damaged endothelium, promoting their accumulation and subsequent release at the IRI site. siRNA@VG-Exos effectively reduced hepatic inflammatory cytokine release, enhanced T-SOD and CAT expression while suppressing MDA generation, thereby alleviating oxidative stress. Furthermore, they promoted the restoration of mitochondrial membrane potential, maintaining mitochondrial homeostasis. Si-IL6 additionally suppressed IL-6 expression in liver tissue, synergistically enhancing the anti-inflammatory effect of G-Exos. Moreover, siRNA@VG-Exos inhibited CD86 expression and promoted CD206 expression in hepatic macrophages, facilitating their polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype and modulating immunity. Ultimately, siRNA@VG-Exos reduced hepatic necrotic areas, lowered ALT and AST levels, and restored liver tissue function. Further sequencing analysis indicated that siRNA@VG-Exos alleviates liver IRI by inhibiting immune and inflammatory responses and oxidative stress damage. Therefore, siRNA@VG-Exos provides a novel targeted strategy for the treatment of liver IRI.",

PGEs were isolated using a tangential flow filtration system, yielding particles with an average diameter of 159.5\u00a0nm and a concentration of 3.9\u2009\u00d7\u20091012 particles/mL. In 3T3-L1 preadipocytes, PGE treatment resulted in a 72.1% reduction in lipid accumulation, as demonstrated by Oil Red O staining, indicating significant inhibition of adipogenic differentiation. Elevated expression of surface markers TET-8 (147.2%) verified the exosomal nature of the isolated vesicles. To determine their role in adipocyte differentiation, we analyzed gene and protein expression of key adipogenic markers-peroxisome proliferator-activated receptor gamma (PPAR-\u03b3), CCAAT/enhancer-binding protein alpha and beta, and fatty acid-binding protein 4-revealing reductions of 23.6-35.6% and 26.7-35.2%, respectively. These results indicate downregulation of transcriptional and translational pathways driving adipogenesis. Lipogenic regulators, including sterol regulatory element-binding protein 1c, acetyl-CoA carboxylase, and fatty acid synthase, were also suppressed by 24.9-41.0% (gene) and 22.8-24.5% (protein), indicating impaired fatty acid synthesis. Conversely, AMP-activated protein kinase (AMPK) expression increased by up to 53.8% (gene) and 47.9% (protein), implying activation of energy homeostasis signaling. Immunofluorescence analysis showed a reduction in the MitoTracker/DAPI ratio (57.7-60.0%) and an increase in the F-actin/DAPI ratio (39.5-60.8%), indicating decreased mitochondrial activity and enhanced cytoskeletal integrity. These molecular changes were accompanied by AMPK activation and PPAR-\u03b3 inhibition.

However, the cellular heterogeneity of diabetic wounds and the specific molecular mechanisms underlying their impaired healing remain unclear. Furthermore, treatment strategies based on medicinal plants targeting these pathological mechanisms are lacking. This study explored diabetic wound pathogenesis using single-cell RNA sequencing (scRNA-seq), revealing a 52\u00a0% reduction in vascular endothelial cells (ECs) and a decreased abundance of proliferative ECs in diabetic wound tissues, which contributed to impaired vascular repair. Network pharmacology and RT-qPCR identified E-selectin (SELE) as the key target of Panax notoginseng in the treatment of diabetic wounds, which was corroborated by molecular docking. Plant-derived extracellular vesicles (EVs) represent a class of superior bioactive nanomaterials compared to traditional extracts, exhibiting high delivery efficiency, molecular transport capacity, and biocompatibility, enabling cross-species communication essential for therapeutic applications. To further overcome limitations associated with plant-derived extracts (e.g., short half-life), we isolated Panax notoginseng EVs and subsequently loaded them into a hydrogel via dynamic borate ester bonds formed between quaternized chitosan-phenylboronic acid (QCS-BA) and konjac glucomannan (KGM), ultimately generating the QBK-2/EVs composite system. This hydrogel not only effectively encapsulated and continuously released EVs, but also exhibited good injectability, self-healing property, tissue adhesion (42.83\u00a0kPa), and ROS/pH-responsive degradation. In vitro, QBK-2/EVs enhanced human umbilical vein endothelial cell proliferation, migration, and tube formation by downregulating SELE and upregulating angiogenesis markers (CD31, F-actin). In vivo, QBK-2/EVs accelerated wound healing in diabetic mice, promoted hemostasis, increased collagen deposition, and enhanced microvessel density (CD31), while simultaneously reducing the expression of SELE. Overall, this work establishes a mechanism-driven strategy for diabetic wound treatment through synergistic exosome-mediated angiogenesis and hydrogel-based delivery.",

We engineered a temporally controlled hydrogel microneedle system that integrates ginseng-derived exosomes (G-Exos) with biomimetic polydopamine nanoparticles (PDA@PEGs) to concurrently target the pathogenic triad of vitiligo, including oxidative stress, inflammation, and melanocyte deficiency. This system employs methacrylated hyaluronic acid (HAMA) hydrogel microneedles for rapid PDA@PEG release while utilizing glyceryl monostearate micelles to achieve matrix metalloproteinase-9 (MMP-9)-responsive G-Exo release at inflammatory foci, enabling intelligent spatiotemporal control. Functionally, G-Exos help restore redox homeostasis and suppress inflammation through bioactive constituents, thereby protecting melanocytes and enhancing keratinocyte proliferation. Moreover, PDA@PEG promotes repigmentation through the dual mechanisms of exogenous melanin deposition and endogenous melanogenesis stimulation. In murine models, this strategy achieves significant repigmentation within 3 weeks by activating follicular stem cells, upregulating melanogenic markers (Tyr/Mc1r), increasing antioxidant defense (ApoE), and suppressing inflammatory signaling (IL-17).

Signal peptides within such proteins are recognized by the signal recognition particle (SRP), which guides them to the ER. When this process is impaired, cells rely on quality control mechanisms to prevent the accumulation of misfolded or mislocalized proteins. One of these mechanisms, known as regulation of aberrant protein production (RAPP), detects nascent proteins with aberrant signal peptides and degrades their mRNA templates. Using functional genetic screens, we identify the zinc finger antiviral protein (ZAP) as a key component of the RAPP pathway. Proteomics and enhanced UV-crosslinking and immunoprecipitation (eCLIP) experiments reveal that the short isoform ZAP-S associates with SRP components and facilitates degradation of aberrant mRNAs. ZAP-S recognizes faulty proteins early in their biogenesis and targets their corresponding mRNAs for degradation. Loss of ZAP activates the unfolded protein response and the downstream integrated stress response, highlighting its central role in safeguarding protein targeting and maintaining cellular homeostasis.",

Plant-derived molecules spanning polyphenols, alkaloids, terpenoids, and cannabinoids are attractive because their pleiotropic actions can engage oxidative stress, neuroinflammation, and circuit dysfunction. In practice, the blood-brain barrier (BBB) restricts most native phytochemicals through tight-junction selectivity, rapid metabolism, low solubility, and transporter-mediated efflux. Key gaps include poor standardization of exposure metrics, limited human-relevant BBB models, and few head-to-head studies that compare delivery platforms on the same payload and outcome. This review tackles the mismatch between mechanistic promise and reliable brain exposure that stalls translation. The objectives are to link phytochemical liabilities to enabling strategies in nanomedicine, alternative routes, and transporter-targeted prodrugs, and to propose decision-grade endpoints for translation. We synthesize evidence on BBB transport logic, nanocarrier families, targeting ligands, intranasal delivery, focused ultrasound-mediated opening, and prodrug approaches that hijack influx transporters, while foregrounding safety and chemistry, manufacturing, and controls (CMC) constraints. Here we highlight that effective neurotherapeutics emerge when chemistry, carrier, route, and measurement are co-designed rather than optimized in isolation. This framework can guide platform selection, de-risk first in-human studies, and sharpen trial endpoints. More broadly, it offers a transferable playbook for barrier-limited drug development across neurology, psychiatry, and oncology.",

This study aimed to investigate the mechanistic basis of NST using long noncoding RNA (lncRNA) and messenger RNA (mRNA) transcriptomics. The metabolites of NST were analyzed. Additionally, its systemically absorbed metabolites (in plasma) and brain-distributed metabolites were identified using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The therapeutic effects of NST were evaluated in a mouse model of middle cerebral artery occlusion (MCAO) using neurological scoring, behavioral testing, cerebral blood flow, and brain tissue staining. LncRNA and mRNA expression profiles were analyzed using the Agilent Mouse competing endogenous RNA microarray, followed by gene ontology and Kyoto encyclopedia of genes and genomes enrichment analyses. Differentially expressed transcripts were validated using quantitative reverse transcription polymerase chain reaction (qRT-PCR). UHPLC-MS/MS analysis detected 129 metabolites in NST; 33 metabolites in plasma; and 17 metabolites in brain tissue of rats administered with NST. NST treatment significantly reduced neurological deficit scores (Longa score), decreased beam-crossing latency, and increased forelimb grip strength in middle MCAO mice, indicating improved neurological function. Additionally, NST treatment enhanced cerebral blood flow recovery, ameliorated pathological damage, restored neuronal architecture, and increased Nissl-stained neuron density in peri-infarct brain tissue. NST also attenuated cellular apoptosis by upregulating Bcl-2 expression and downregulating Bax protein levels, exerting neuroprotective effects. Notably, NST treatment reversed 177 out of 5,378 differentially expressed IncRNAs and 52 out of 5,540 differentially expressed mRNAs that were dysregulated between the model and sham groups. These NST-modulated IncRNAs participate in key biological processes, including synaptic modulation, apoptosis regulation, and neuronal function. A synaptic plasticity-associated lncRNA-mRNA coexpression network was developed using NST-reversed transcripts. Validation using qRT-PCR confirmed the upregulation of NONMMUT050688.2 and NONMMUT044667.2, and the downregulation of NONMMUT092269.1 and NONMMUT101071.1, the downregulation of Nrn1, the upregulation of Grn, and the downward trend in Rasd2 expression in MCAO mice. All these alterations were reversed through NST treatment. In vivo experiments confirmed the efficacy of NST in ameliorating memory deficits, mitigating synaptic structural damage, and upregulating key synaptic protein expression (SYN and PSD95) in mice.

This review distinguishes itself by integrating mechanistic insights into nasal transport pathways with the rational design of advanced nano-delivery systems. We first outline the challenges in CNS drug delivery and detail the nasal anatomy and transport pathways facilitating nose-to-brain delivery. Subsequently, we emphasize the critical properties required of advanced nano-carriers to improve mucosal penetration, prolong retention, and promote drug accumulation at cerebral injury sites. Following a detailed analysis of the advantages and limitations associated with nose-to-brain delivery, we consolidate recent advances in nasal nano-delivery systems for treating CNS disorders, emphasizing their capacity to improve brain-targeting efficiency, enhance therapeutic efficacy, reduce systemic toxicity, and enable previously undruggable CNS targets. Finally, we expand the discussion to encompass current challenges impeding clinical translation, including safety concerns, manufacturing scalability, and regulatory hurdles, while highlighting emerging trends such as artificial intelligence-driven formulation design. This comprehensive analysis aims to deepen the understanding of nasal-to-brain transport mechanisms and inform the future development of effective nasal formulations for improved neurological therapeutics.",
"41875607": "ID: 41875607\nTitle: Nose-to-brain delivery of berberine-loaded nanoemulsion: Amelioration of brain targeting, behavioral, pharmacokinetic, and biodistribution insights for Alzheimer's intervention.\nAbstract: Berberine (BER), a benzylisoquinoline alkaloid, has garnered attention for its multifaceted pharmacological properties, including pronounced antioxidant, anti-inflammatory, and neuroprotective effects. Despite its therapeutic potential in neurodegenerative disorders, including Parkinson's disease, cerebral ischemia, and epilepsy, its clinical translation in Alzheimer's disease (AD) is hindered by poor aqueous solubility, limited systemic bioavailability, and restricted blood-brain barrier (BBB) permeability. This study aimed to overcome these limitations by formulating a BER-loaded nanoemulsion (BER-NE) for intranasal (IN) delivery to achieve direct nose-to-brain (N2B) targeting. The optimized NE exhibited a droplet size of 138.5\u00a0\u00b1\u00a00.96\u00a0nm and a polydispersity index (PDI) of 0.203\u00a0\u00b1\u00a00.007, indicating a monodisperse system. The BER-NE demonstrated a drug content of 99.62\u00a0\u00b1\u00a01.02%, confirming efficient drug incorporation. In vitro studies on SH-SY5Y neuroblastoma cells demonstrated that BER-NE reduced reactive oxygen species (ROS) levels by 2.09-fold and restored mitochondrial membrane potential (MMP) with a 3.61-fold increase in red/green fluorescence intensity compared to SCOP-induced cells. Further, pharmacokinetic (PK) profiling revealed that IN BER-NE achieved a 3.2- and 3.6-fold increase in brain Cmax compared to BER-SUS IN and BER-NE IV, respectively. The IN BER-NE demonstrated a 1.7- and 1.9-fold increase in %DTE and %DTP compared to the IN SUS, which supports the efficient N2B delivery. Behavioral assessments demonstrated dose-dependent reversal of SCOP-induced cognitive, depressive, and motor impairments. Additionally, treatment with HD BER-NE and MD BER-NE via the IN route markedly reduced the nitrite accumulation by 4.3- and 3.5-fold compared to the SCOP group, indicating attenuation of nitrosative stress. Collectively, these findings underscore the potential of IN BER-NE as a targeted and non-invasive therapeutic strategy for the management of AD.",

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations.",

The blood-brain barrier (BBB), systemic toxicity, and first-pass metabolism are key obstacles. These factors limit the effective drug delivery to the brain. Intranasal administration has emerged as a noninvasive strategy to bypass the BBB. This approach enables direct drug delivery to the brain through the olfactory and trigeminal nerve pathways, commonly referred to as nose-to-brain (N2B) delivery. In this context, chitosan (CS), a biocompatible and mucoadhesive polysaccharide with permeation-enhancing properties, has gained significant interest as a functional material for nanoparticle (NP) engineering. CS-based or CS-coated NP can prolong the residence time on the nasal mucosa and facilitate drug transport to the CNS. This review provides a comprehensive overview of recent advances in CS-based NP for N2B drug delivery across a range of CNS disorders, including neurodegenerative, neuropsychiatric, neoplastic, and infectious conditions. Particular attention is given to formulation strategies, mechanistic insights, and preclinical outcomes. Recent patent applications are surveyed to underscore the translational potential and commercial interest in this technology.

Consequently, this route has been extensively investigated for treating diverse brain disorders, ranging from acute conditions to neurodegenerative diseases. Despite the advantages and clinical approval of several nasal products, the need for effective disease-modifying therapies (DMTs) of brain disorders remains unmet. Given that most brain disorders involve region-specific or cell-type-specific pathological changes, and that off-target effects may result in central nervous system toxicity, precision nose-to-brain delivery is critical. A major challenge to its clinical translation remains the lack of predictive, human-relevant preclinical models. Therefore, this review explores the challenges in nose-to-brain drug delivery development, highlights advanced intranasal delivery strategies for treating brain disorders, and discusses emerging in vitro models for evaluating nose-to-brain delivery efficiency. The work aims to promote the development and clinical translation of intranasal brain-targeted therapeutics.",

However, the blood-brain barrier (BBB) prevents over 98% of therapeutics from reaching brain tissue. Intranasal delivery provides a promising alternative by exploiting olfactory and trigeminal nerve pathways to circumvent the BBB. This review surveys recent advances in nose-to-brain delivery technologies, from carrier design to evaluation methods. Polymeric and lipid-based nanocarriers show enhanced mucosal penetration and prolonged residence time, and microneedle platforms further enable controlled drug release with minimal discomfort. To evaluate these delivery strategies, sensor-integrated organ-on-chip models provide more physiologically relevant testing than static cultures. Although persistent challenges such as rapid mucociliary clearance and formulation stability remain, combining nanotechnology with microfluidic devices and computational modeling shows potential for developing patient-specific therapeutics.",

Panax notoginseng, a traditional medicinal herb, exhibits well-documented cardioprotective properties; however, the therapeutic application of its bioactive constituents is constrained by poor bioavailability and potential toxicity. Plant-derived extracellular vesicles (EVs) have emerged as natural nanocarriers facilitating cross-kingdom delivery of bioactive metabolites. In this study, we investigated whether P. notoginseng-derived EVs (PEVs) could mitigate Dox-induced cardiotoxicity (DIC) and explored the underlying mechanisms. PEVs were isolated from P. notoginseng rhizomes and systematically characterized, with metabolite profiling performed by UPLC-MS. Cellular uptake, biodistribution, and cardioprotective effects were evaluated in Dox-injured cardiomyocytes and a chronic mouse model of DIC. Mechanistic insights were obtained using transcriptomic analysis, molecular docking, and biochemical assays. PEVs were stable nanosized vesicles enriched with characteristic P. notoginseng metabolites, including triterpenoid saponins and dencichine. PEVs were efficiently internalized by cardiomyocytes and preferentially accumulated in injured myocardium. Functionally, PEVs attenuated Dox-induced inflammation, apoptosis, myocardial atrophy, fibrosis, and cardiac dysfunction, with efficacy comparable to dexrazoxane. Mechanistically, transcriptomic and molecular analysis identified p53 as a central regulatory target. PEVs-derived metabolites targeted the p53 DNA-binding domain, suppressing p53 phosphorylation and transcriptional activation of pro-apoptotic and inflammatory genes. Notably, p53 activation attenuated PEVs-mediated protection, whereas p53 inhibition or silencing abolished additional protective effects, indicating a p53-dependent mechanism. PEVs protect against DIC by delivering bioactive metabolites to injured myocardium and inhibiting p53-driven oxidative, inflammatory, and apoptotic pathways, highlighting their potential as a phytomedicine-based cardioprotective strategy.",

Meyer) is a classic herbal medicine widely utilized in dermatological management, yet its precise therapeutic mechanisms have only recently begun to be fully elucidated. This review systematically synthesizes the pharmacological roles of ginseng's active components, including ginsenosides, polysaccharides, and gintonin, in maintaining skin homeostasis and treating various cutaneous pathologies. Emerging evidence suggests that the efficacy of ginseng extends beyond direct molecular interactions, exhibiting the distinct characteristics of \"indirect pharmacology.\" Specifically, parent ginsenosides function primarily as natural prodrugs that require microbial biotransformation into high-affinity active metabolites, such as Compound K and Rh2, to exert potent therapeutic effects. Functionally, these components regulate skin health by mobilizing endogenous host defense systems, particularly through the activation of the Nrf2/ARE antioxidant pathway and the suppression of inflammatory cascades via the NF-\u03baB, MAPK, and IL-1 signaling networks. Furthermore, they remodel the systemic microenvironment through the gut-skin axis, facilitating metabolic homeostasis to improve skin barrier function. Notably, biotransformation rates and ultimate therapeutic efficacy are highly dependent on individualized variables, such as host age, dietary patterns, and baseline disease states. This systemic regulation has demonstrated robust efficacy in intervening in complex pathologies, including atopic dermatitis, psoriasis, and skin cancer. Additionally, this article addresses the translational bottleneck of low bioavailability and evaluates recent advances in novel skin delivery systems, specifically those utilizing ginseng-derived exosomes. Collectively, this review provides a scientific framework for understanding the systemic actions of ginseng, supporting its development as a precision botanical therapy for dermatological applications.",

Understanding these modules and how they evolve over time can be accomplished by constructing gene regulatory networks (GRNs). To identify context-specific TF subnetworks, we developed ChEA-KG, which generates enriched TF regulatory subnetworks for input gene sets. ChEA-KG is based on a GRN connecting 1559 human TFs via 131\u2009181 signed and directed edges inferred from diverse published ChIP-seq (chromatin immunoprecipitation followed by sequencing) and mRNA (messenger RNA)-sequencing experiments. We demonstrate ChEA-KG's utility by applying it to uncover master regulators of aging, mechanisms of action (MoA) for drug classes, pan-cancer subtypes, and cell types from across 14 major human tissues. Next, we extend ChEA-KG to develop the webserver application ChEA-KG Time Series (ChEA-KG-TS), which identifies TF modules from time-series mRNA-sequencing datasets. Results from this workflow are automatically summarized as reports that include enrichment analysis, regulatory subnetworks, and UMAP projections of enriched TFs. We use ChEA-KG-TS to explain transient responses in two use cases. ChEA-KG and ChEA-KG-TS are available from\u00a0https://chea-kg.maayanlab.cloud/ and https://chea-kg-ts.maayanlab.cloud/.",

To overcome these limitations, a Lactoferrin (Lf)-functionalized BXP-loaded nanostructured lipid carrier (Lf-BXP-NLC) incorporated into a thermoresponsive in situ nasal gel was developed to enable sustained and receptor-mediated nose-to-brain transport. The optimized formulation demonstrated nanoscale particle size (<200\u00a0nm), narrow polydispersity, high entrapment efficiency (\u223c88%), and physiological gelation temperature (30-34\u00a0\u00b0C), with preserved physicochemical stability over 3\u00a0months. In vitro release and ex vivo permeation studies confirmed controlled drug release and enhanced mucosal transport. In vivo pharmacokinetic evaluation in rats revealed significantly improved brain exposure following intranasal administration, with approximately 1.9-fold higher AUCbrain compared with drug suspension and 1.97-fold greater exposure relative to intravenous delivery. A rapid brain Tmax (0.41\u00a0h) and direct transport percentage of\u00a0\u223c\u00a062% indicated dominant neuronal pathway involvement and reduced reliance on systemic circulation. Enhanced pharmacokinetics translated into pronounced pharmacodynamic benefits in ketamine-induced schizophrenia models, including significant attenuation of stereotypic behaviors, restoration of motor coordination, and near-normalization of neuromuscular performance. Cross-species validation in zebrafish further demonstrated substantial correction of anxiety-like behavior and cognitive impairment, reinforcing translational robustness. Importantly, no nasal ciliotoxicity was observed. Collectively, this multifunctional intranasal nanocarrier platform achieves rapid, sustained, and targeted brain delivery of BXP and offers a promising non-invasive strategy for precision neuropsychiatric therapy.",

Effective drug delivery to the brain is largely constrained by the selective nature of the blood-brain barrier (BBB), which limits therapeutic efficacy of conventional oral medications. Intranasal administration has emerged as a noninvasive and promising route for direct nose-to-brain transport, circumventing BBB restrictions. This review explores the potential of intranasal drug delivery as an alternative approach for targeted brain therapy in Alzheimer's disease. It comprehensively discusses the mechanisms of nasal absorption, physiological and formulation-related barriers, and the role of advanced nanocarrier platforms in overcoming these limitations. Emphasis is placed on recent innovations involving polymeric, lipid-based, and vesicular carriers, along with the incorporation of mucoadhesive and permeation-enhancing agents. The present focus is enhancing bioavailability, prolonging drug residence time, and minimizing systemic toxicity. Surface modifications of nanocarriers further facilitates mucosal adhesion and enables effective nose-to-brain transport of encapsulated therapeutic agents. However, clinical translation remains challenging due to interindividual variability in nasal physiology, scalability constraints, and regulatory complexities. Future progress will depend on the rational design of multifunctional nanocarriers, integration of mucoadhesive and stimuli-responsive components, and the use of precision-based formulation strategies.",

This complexity makes it challenging to identify the key genes and the specific alleles that confer tolerance. We used time-course expression analysis to profile gene and miRNA expression associated with salt tolerance in Pokkali, a salt-tolerant rice variety. We established a framework for studying transcription factor-target(mRNA/miRNA) interactions using gene co-expression and machine-learning models. Moreover, we developed a hypergeometric distribution-based method to elucidate the interactions of salt stress-related miRNA-targets. Using these approaches, we established co-expression (GCN) and gene regulatory networks (GRN) based on co-expression and TF/miRNA-target interactions. Hub genes with high connectivity in our networks were enriched for previously reported salt tolerance genes, a finding largely supported by subsequent haplotype analysis of 374 rice accessions. Finally, we functionally validated three crucial hub genes, OsCAF1B, OsADR3 and Ospdr9, by demonstrating their roles in salt tolerance using their knockout mutants. The crucial genes, haplotypes and networks for salt tolerance identified in this study (resource available at https://cbi.njau.edu.cn/RiceSALTnet) provide a foundation for breeding rice cultivars with enhanced salt tolerance.",

However, conventional dopaminergic therapies remain limited by poor blood-brain barrier (BBB) penetration, rapid systemic metabolism, short half-life, peripheral toxicity, and dopamine oxidation-induced neurotoxicity. Nanomedicine-based drug delivery systems have emerged as promising strategies to overcome these limitations by enhancing dopamine stability, improving BBB transport, enabling controlled release, and facilitating targeted delivery to dopaminergic brain regions. This review comprehensively summarizes current advances in dopamine-targeted nanotherapeutics, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, dendrimers, inorganic nanoparticles, exosomes, and biomimetic vesicles. Particular emphasis is placed on the dual role of nanocarriers in both facilitating dopamine delivery and protecting dopamine from oxidative degradation and reactive oxygen species-associated toxicity. Among currently investigated platforms, polymeric nanoparticles, lipid-based nanocarriers, and exosome-inspired vesicles appear particularly promising due to their ability to improve dopamine stability, facilitate controlled release, enhance BBB penetration, and enable targeted brain delivery. The review additionally discusses receptor-mediated targeting strategies, intranasal delivery approaches, translational barriers, manufacturing scalability, long-term safety considerations, and regulatory challenges associated with clinical implementation. Finally, emerging future directions involving AI-assisted nanocarrier engineering, precision-targeted delivery systems, and stimuli-responsive nanomedicine are highlighted as promising approaches for the development of next-generation therapies for neurodegenerative disorders.",

We sought to build a cross-disease, multi-region, quantitative map of CSF1R-positive microglia in neurodegenerative conditions and progressive multiple sclerosis (MS) lesions, with an exploratory comparison to presynaptic marker burden. CSF1R mRNA\u2011positive microglia were quantified by RNAscope across six cortical regions (MFG, IFG, ITG, AG, CA1, EC) in early\u2011onset Alzheimer's disease (EOAD), late\u2011onset AD (LOAD), progressive supranuclear palsy (PSP), and frontotemporal lobar degeneration with TDP-43 inclusions due to progranulin mutation (FTLD\u2011GRN), and in primary and secondary progressive MS (PPMS, SPMS) within cortical gray\u2011matter plaques, plaque-adjacent gray matter and white matter. Positivity was defined a priori as\u2009\u2265\u20093 puncta with housekeeping\u2011probe pass and negative\u2011control verification, counting blinded, and densities were cortical\u2011thickness corrected. Iba-1 immunolabeling verified microglial identity. Western blot provided protein\u2011level verification. We explored ROI\u2011level associations of CSF1R with SV2A and synaptophysin previously measured in the same regions/cases. In neurodegeneration, increases were smaller and region\u2011specific (e.g., EOAD-ITG/CA1; LOAD-AG; PSP-AG; FTLD\u2011GRN-IFG/ITG/AG/EC), with minimal white\u2011matter change. In progressive MS, gray-matter CSF1R-positive microglia densities did not differ from controls, whereas SPMS white matter was increased. Exploratory analysis showed that CSF1R and SV2A were positively associated across ROIs in neurodegenerative diseases (e.g., PSP approximately \u03c1\u2009=\u20090.66), and weakest in LOAD; synaptophysin showed similar patterns, suggesting that regions with higher CSF1R-positive microglia density can coincide with relative preservation of presynaptic markers. A cross\u2011disease, region\u2011resolved map reveals region\u2011specific changes in CSF1R\u2009+\u2009cell density in neurodegeneration, but only white matter in MS. These findings provide the histological context needed to interpret future CSF1R\u2011PET. Prospective studies pairing CSF1R\u2011PET with SV2A\u2011PET and multiplex tissue profiling are warranted to define microglial states and synaptic outcomes in vivo.",

MERLIN-SUITE (https://github.com/Roy-lab/MERLIN-SUITE) represents a collection of algorithmic extensions based on MERLIN (Modular regulatory network learning with per gene information) a probabilistic framework that infers gene-specific and module-specific regulatory programs of co-regulated modules, capturing both detailed and modular aspects of transcriptional networks. While expression-based inference is effective, it often aligns poorly with experimentally validated regulatory interactions. MERLIN-P addresses this by integrating external regulatory priors, such as motif, ChIP, and perturbation data, to enhance biological relevance and predictive accuracy. MERLIN-P-TFA further advances the framework by incorporating regularized estimation of latent transcription factor activity (TFA), overcoming the limitation that TF mRNA levels may not represent protein activity. By integrating expression data, prior knowledge, and activity-aware modeling, this unified approach supports robust GRN reconstruction in both bulk and single-cell datasets. This chapter presents the MERLIN-SUITE with a focus on MERLIN-P-TFA and demonstrates its use on a single-cell, multi-modal dataset of mouse cellular reprogramming to infer GRNs and identify key regulators.",

In this study, we examined the effects of glucosamine (GlcN), a hexosamine biosynthetic pathway intermediate, on autophagy and lipid accumulation using both human hepatocellular carcinoma (HepG2) cells and a high-fat diet (HFD)-induced NAFLD mouse model. GlcN treatment led to a dose- and time-dependent increase in the expression of autophagy-related markers LC3 and p62 at both mRNA and protein levels. Pharmacological inhibition of O-GlcNAcase (OGA) further enhanced autophagic activity, whereas inhibition of O-GlcNAc transferase (OGT) abrogated GlcN-induced autophagic responses, implicating O-GlcNAcylation as a key mediator of GlcN-driven autophagy induction. Functionally, GlcN significantly reduced palmitic acid (PA)-induced lipid accumulation in HepG2 cells and alleviated hepatic steatosis in HFD-fed mice, likely through enhancement of autophagic flux. These findings demonstrate that GlcN promotes lipid clearance in hepatocytes via O-GlcNAc-dependent autophagy and highlight its potential as a therapeutic agent for NAFLD and related metabolic disorders.",
"42480145": "ID: 42480145\nTitle: Panasenoside promotes angiogenesis and mitigates vascular endothelial cell senescence via SIRT1 activation.\nAbstract: Angiogenesis is a crucial process in ischemia diseases like coronary heart disease, stroke and wound healing. Panasenoside (PSS) is a flavonoid glycoside ioslated from Chinese Materia Medica GINSENG RADIX ET RHIZOMA which has been demonstrated with multiple biological activities. However, the pharmacological activity of PSS and the underlying mechanism are still unclear. We found that PSS promoted sub-intestinal vessel plexus (SIVs) growth in zebrafish. PSS ameliorated vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor II (VRI)-induced deficiency of intersegmental vessels (ISVs) in a concentration dependent manner by downregulation of mRNA expression of VEGF receptors, including Kdr/VEGFR-2 (kdr), VEGFR-1 (flt1), and Kdr-like/VEGFR-2 (kdrl), and up-regulation of VEGF (vegfaa). The angiogenesis effect of PSS on VRI-induced ISVs deficiency was suppressed by PI3K, AKT, MEK, ERK, P38, Sirtuin 1 (SIRT1), Nuclear factor erythroid-2-related factor 2 (NRF2) and Nicotinamide N-methyl transferase (NNMT) inhibitors. Activation of NRF2, SIRT1 and MNA significantly restored VRI-induced ISVs insufficiency. In addition, PSS protected against VRI-induced tube formation deficiency in human umbilical vascular endothelial cells (HUVECs). SIRT1, NRF2 and NNMT inhibitors or siRNA eliminated PSS promoting vascular endothelial cell tube formation. PSS also prevented SIRT1, NRF2 and NNMT inhibitors-induced vascular endothelial cell senescence. Furthermore, PSS upregulated the protein expression level of SIRT1 and downregulated its downstreams P53 and PGC-1\u03b1 in HUVECs with high potence of activating SIRT1 by binding with its active domine. In conclusion, PSS presented pro-angiogenesis effect by mitigating vascular endothelial cell ageing and the underlying mechanisms were involved in the PI3K/AKT/MAPKs, SIRT1/NRF2 and NNMT/MNA signaling pathway with SIRT1 acting as a key regulator. We identified the pro-angiogenesis and anti-vascular endothelial cell ageing effects of PSS for the first time, and PSS is a promising drug candidate for treating vascular deficiency associated diseases.",

Using a multifaceted approach in mice, we examined tracer dynamics and the CSF outflow pathway from the subarachnoid space (SAS) to the nasal mucosa and identified a discrete arachnoid region surrounding the olfactory bulbs with abundant fenestrations. Similar arachnoid fenestrations were found in cynomolgus monkeys. Fluorescent tracers in the SAS passed through arachnoid fenestrations into dural lymphatics, which traversed the cribriform plate foramina, joined the nasal lymphatics, and drained to the cervical lymph nodes. In aged mice, the known reduction in CSF outflow was accompanied by lymphatic atrophy in the olfactory dura and nasal mucosa and by fewer arachnoid fenestrations and smaller cribriform plate foramina. Importantly, the lymphatics and CSF clearance were restored to normal by intranasal delivery of vascular endothelial growth factor-C (VEGF-C), thereby documenting the reversibility of the aging-related impairment in CSF clearance.",

Currently, no effective therapeutic agents are available, and surgery remains the mainstay of treatment for MPT. Niclosamide ethanolamine (NEN), an antiparasitic agent, has recently demonstrated broad-spectrum antitumor activity against various solid malignancies. This study aimed to evaluate the antitumor efficacy of NEN against MPT and elucidate the underlying molecular mechanisms. The effects of NEN on MPT cell proliferation and migration were assessed using CCK-8, wound healing, and Transwell migration assays. Ultrastructural alterations following NEN treatment were examined by transmission electron microscopy. Bioinformatics analyses, quantitative real-time PCR (qPCR), Western blotting, and immunofluorescence staining were employed to investigate the molecular mechanisms underlying NEN-mediated modulation of autophagy and lysosomal function. NEN significantly inhibited MPT cell proliferation and migration. Transmission electron microscopy revealed the accumulation of numerous autolysosomal structures in NEN-treated cells. Mechanistically, NEN suppressed mTOR phosphorylation, promoted nuclear translocation of transcription factor EB (TFEB), and induced lysosomal biogenesis. However, lysosomal function was compromised, as evidenced by elevated luminal pH, impaired cathepsin D maturation, and lysosomal membrane permeabilization, ultimately resulting in autophagic flux blockade at the degradation stage. Furthermore, lysosomal cathepsin leakage activated the mitochondrial apoptotic pathway, culminating in caspase-3-dependent apoptosis. NEN effectively kills MPT cells by inducing \"lysosomal biogenesis-function uncoupling.\" This study is the first to reveal a novel anti-MPT mechanism that targets the mTOR-TFEB-lysosome axis and disrupts lysosomal homeostasis, providing a potential drug candidate for the treatment of MPT.",

This study investigates the therapeutic potential of adipose-derived mesenchymal stem cells (AD-MSCs) and their exosomes (AD-MSCs-Exo) in ameliorating NAFLD-induced testicular dysfunction in a murine model. Male C57BL/6 mice were divided into four groups: [n\u2009=\u20098 per group: control, high-fat diet (HFD), HFD\u2009+\u2009AD-MSCs, and HFD\u2009+\u2009AD-MSCs-Exo]. Sperm parameters according to the WHO Laboratory Manual, hormonal profiles via ELISA, and expression of genes involved in autophagy and spermatogenesis were assessed using qRT-PCR. HFD-induced NAFLD significantly reduced sperm count (P\u2009=\u20090.036), motility (P\u2009<\u20090.0001), viability (P\u2009=\u20090.023), and normal morphology (P\u2009=\u20090.015) while increasing DNA fragmentation (P\u2009=\u20090.004). Moreover, in the HFD group, LH and total testosterone levels decreased significantly (P\u2009=\u20090.0002 and P\u2009<\u20090.0001), whereas estradiol levels increased significantly (P\u2009=\u20090.0001) compared with controls. Expression of STAR was significantly downregulated (P\u2009=\u20090.0001); conversely, the relative fold changes of BECN1 (P\u2009=\u20090.0003), MAP-LC3b-a (P\u2009=\u20090.0002), and SQSTM-1/p62 (P\u2009=\u20090.005) were significantly enhanced in the HFD group compared to the controls. Treatment with AD-MSCs or AD-MSCs-Exo improved sperm quantity and quality and balanced hormonal levels. AD-MSCs showed slightly greater modulation of key autophagy genes (BECN1, MAP-LC3b-a, and SQSTM1/p62), whereas exosomes were more effective in hormonal restoration (especially testosterone) and in enhancing genes related to steroidogenesis (especially INHBB). AD-MSCs and their exosomes improve sperm-related abnormalities, hormonal imbalance, and testicular autophagy dysregulation in the NAFLD model. These findings support their potential as therapeutic agents for NAFLD-induced male infertility, highlighting translational relevance while noting the need for further clinical validation.",
"42481908": "ID: 42481908\nTitle: A Study on the Effects of Intranasally Administered Liquid Crystalline Nanoparticles Loaded with Salvianolic Acid B in Vascular Dementia.\nAbstract: Salvianolic acid B (SalB) is a bioactive polyphenol with therapeutic potential for vascular dementia (VD), but poor penetration across the blood-brain barrier (BBB) and low bioavailability restrict its clinical translation. To address these problems, a SalB-loaded liquid crystalline nanoparticle delivery system (SalB-LCN) was constructed and systematically characterized in terms of its physicochemical properties. Meanwhile, an intranasal administration strategy was employed to bypass the BBB, and the therapeutic effects of SalB-LCN on VD were systematically evaluated. The results showed that SalB-LCN possessed favorable morphology and sustained-release properties, enabling stable encapsulation and continuous release of SalB. In vitro experiments demonstrated that SalB-LCN exhibited good biocompatibility and could alleviate oxidative damage in neuronal cells. In a bilateral common carotid artery occlusion-induced rat model of VD, SalB-LCN significantly improved learning and memory abilities, alleviated hippocampal neuronal morphological damage, and exhibited good in vivo biosafety. Further studies showed that SalB-LCN markedly lowered reactive oxygen species levels, suppressed IL-1\u03b2 and IL-18 production in hippocampal tissues, and reduced cell death as well as lactate dehydrogenase activity. In addition, SalB-LCN also suppressed NLRP3/Caspase-1/GSDMD signaling. In conclusion, intranasal delivery of SalB-LCN improved brain delivery by facilitating transport across the BBB and conferred neuroprotection against VD through modulation of oxidative stress, inflammation, and NLRP3/Caspase-1/GSDMD signaling, highlighting its translational potential as a nanomedicine-based therapeutic strategy.",
"42482577": "ID: 42482577\nTitle: [Mechanism of acupuncture at \"Houxi\"(SI3) and \"Huantiao\"(GB30) in influencing autophagy of nucleus pulposus cells by regulating PI3K/AKT/mTOR signaling pathway in rats with lumbar intervertebral disc degeneration].\nAbstract: To observe the effect of acupuncture at the acupoint pair \"Houxi\"(SI3) and \"Huantiao\"(GB30) on the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway and autophagy of nucleus pulposus cells in a rat model of intervertebral disc degeneration (IDD), so as to explore its underlying mechanism in delaying IDD. A total of 36 male SD rats were randomly assigned to sham operation, model and acupoint pair groups, with 12 rats in each group. The IDD model was established by annulus fibrosus puncture. After modeling, rats of the acupoint pair group received acupuncture stimulation of bilateral SI3 and GB30, with the acupuncture needles retained for 20 min, once daily for 14 consecutive days. Before and after modeling and after the intervention, the mechanical withdrawal reflex threshold (mechanic pain threshold) of the right foot was measured using VonFrey filaments, and the thermal pain threshold measured by using a thermal pain tester. The morphological characteristics of the intervertebral disc tissue were observed by H.E. staining. The contents of type \u2161 collagen (Collagen \u2161), Aggrecan, matrix metalloproteinase 3 (MMP3), matrix metalloproteinase 13 (MMP13), and transcription factor sex-determining region Y-box protein 9 (SOX9) in the nucleus pulposus tissue were detected by ELISA. The mRNA relative expression levels of SOX9 and MMP13 in the nucleus pulposus tissue were detected by real-time fluorescence quantitative PCR. The positive expression of microtubule-associated protein 1 light chain 3 (LC3) in the nucleus pulposus tissue was detected by immunofluorescence staining. The expression levels of PI3K/AKT/mTOR signaling pathway-related proteins and LC3- \u2161, Beclin1, and chaperone 1 (p62) in the nucleus pulposus tissue were detected by Western blot. After modeling, in contrast to the sham operation group, the model group showed a striking decrease in the mechanical and thermal pain thresholds on day 7 and 14, contents of Aggrecan, collagen \u2161 and SOX9, and the expression levels of SOX9 mRNA and p62 protein, ratios of p-PI3K/PI3K, p-AKT/AKT, and p-mTOR/mTOR in the nucleus pulposus tissue (P<0.001, P<0.01), and a notable increase in the contents of MMP3 and MMP13, and MMP13 mRNA expression level, LC3 immunofluorescence intensity, and protein expressions of LC3-\u2161 and Beclin 1 (P<0.001). Under light microscope, the nucleus pulposus cells in the model group was relatively small in the number and discorded in the distribution, with a large number of vacuoles and chaotic matrix arrangement, and the lumbar intervertebral discs showed obvious degeneration, and decrease in the height. In comparison with the model group, both the decrease and increase of the indexes mentioned above were all reversed in the acupoint pair group (P<0.001, P<0.01, P<0.05). The results of H.E. stain displayed that in the acupoint pair group, the arrangement of the nucleus pulposus cells was more regular, and the number of vacuoles was reduced. Acupuncture of acupoint pair SI3 and GB30 can mitigate pain and regulate the autophagy process of lumbar intervertebral disc nucleus cells, reduce the degree of degradation of cytoplasmic matrix, and thereby delay the progression of IDD, which may be associated with its function in activating PI3K/AKT/mTOR signaling pathway in IDD rats. \u76ee\u7684:

"42484065": "ID: 42484065\nTitle: Global Phosphoproteome Analysis Identifies CLK4 Co-Regulatory Pathways Driving Tumor-Specific Dysregulation.\nAbstract: Dual-specificity protein kinase CLK4 plays a pivotal role in regulating alternative mRNA splicing, DNA repair, and various cellular processes through precise phosphorylation. In this study, we analyzed 3825 global human cellular phosphoproteome studies, identifying 430 qualitative profiles and 55 quantitative differential datasets featuring high-confidence Class-1 phosphosites (localization probability \u2265 75%; A-score \u2265 13). Notably, S136 and S138 emerged as predominant phosphorylation sites outside the kinase domain. These sites showed frequent detection and differential expression in liver, lung, and head and neck cancers, as documented in PhosphositePlus. We identified a high-confidence set of co-regulated phosphoproteins, including SQSTM1, SRRT, RPS6, TP53BP1, TNKS1BP1, THUMPD1, OTUD4, and TCEA1. These proteins link CLK4 to critical pathways, including RNA splicing, autophagy, DNA damage response, and cancer progression. Binary interactors, including SRRM2, Interacts with SPT6 1 (IWS1), RBBP6, ZC3H18, BUD13, and DYRK1A, further connect CLK4 to RNA processing and splicing. Predicted downstream substrates, such as CCNL2, CDK11B, PRDX6, YTHDC1, RBM15, SRRM1, SFSWAP, HNRNPU, and DOCK7, highlight CLK4's broad regulatory scope. Upstream kinases were also predicted for S136 and S138. Site-resolved analyses revealed tumor-specific dysregulation of CLK4 phosphorylation at key residues. Co-occurring phosphosite alterations and nearby somatic mutations suggest disrupted CLK4 regulation in cancer. Overall, this study provides a comprehensive phosphoproteomic resource that maps CLK4's co-regulatory networks, paving the way for mechanistic investigations and targeted cancer therapies.",

This study aimed to provide randomised comparative evidence on the efficacy and safety of thiotepa-based HCT-ASCT versus non-myeloablative R-DeVIC consolidation after uniform MATRix induction in newly diagnosed PCNSL. This open-label, randomised, phase 3 trial was conducted across 56 university and academic non-university hospitals with established transplantation facilities in five European countries. Eligible for inclusion were untreated, immunocompetent patients with B-cell PCNSL, aged 18-65 years regardless of Eastern Cooperative Oncology Group (ECOG) performance status, or 66-70 years with ECOG performance status 0-2. Pretreatment corticosteroids were permitted. Exclusion criteria included lymphoma manifestation outside the CNS, and congenital or acquired immunodeficiency. Patients received four cycles of MATRix induction (comprising rituximab, high-dose cytarabine, and thiotepa, in addition to high-dose methotrexate). Patients reaching at least partial response were randomly assigned (1:1) to two cycles of R-DeVIC (rituximab plus dexamethasone, etoposide, ifosfamide, and carboplatin) or HCT-ASCT with carmustine and thiotepa. The primary endpoint was progression-free survival, assessed in the full analysis set (excluding patients with major violations of entry criteria). The safety analysis set contained all randomised patients who initiated therapy. This study is registered with ClinicalTrials.gov (NCT02531841) and the EU Clinical Trials Register (EudraCT number 2012-000620-17). The study is completed. Between July 16, 2014, and Aug 31, 2019, 368 patients were enrolled. 346 (94%) patients started induction treatment, and 230 were randomly assigned; 229 patients were analysed (R-DeVIC group, n=115; HCT-ASCT group, n=114). After a median follow-up of 45\u00b73 months, 3-year progression-free survival was significantly superior in the HCT-ASCT group (hazard ratio 0\u00b743 [95% CI 0\u00b727-0\u00b768]; p=0\u00b70003). The 3-year progression-free survival was 78% (95% CI 69-85) in the HCT-ASCT group compared with 51% (41-60) in the R-DeVIC group. The mean number of adverse events per patient was 9\u00b73 (SD 4\u00b74) in the R-DeVIC group and 14\u00b76 (5\u00b78) in the HCT-ASCT group. Fatal serious adverse events following consolidation treatment occurred in two patients in the R-DeVIC group (both acute myeloid leukaemia) and in five patients in the HCT-ASCT group (infections and infestations [n=4], pulmonary embolism [n=1]); all of these events apart from the pulmonary embolism were judged to be possibly related to treatment. In the largest randomised trial in untreated PCNSL to date, HCT-ASCT significantly improved progression-free and overall survival compared with non-myeloablative consolidation in patients who had completed induction treatment, establishing it as the preferred consolidation strategy in fit patients.

"42486454": "ID: 42486454\nTitle: Yishen Tongluo formula regulates apoptosis and autophagy in testicular spermatogenic cells of oligoasthenozoospermic rats via the AMPK/mTOR pathway.\nAbstract: Yishen Tongluo Formula (YSTLF) is a modern compound formula derived from the traditional Chinese medicine (TCM) theory of \"kidney deficiency and collateral obstruction\", and consists of seven Chinese medicinal herbs. It has been used clinically to treat oligoasthenozoospermia (OAS) for more than two decades, with proven efficacy and a favorable safety profile. However, its precise molecular mechanism has yet to be fully elucidated. The aim was to investigate the therapeutic efficacy and the underlying mechanism of YSTLF in treating OAS associated with the kidney deficiency and collateral obstruction pattern. The chemical constituents of YSTLF were identified by UHPLC-Q-Orbitrap HRMS, and molecular docking was performed between the ten most abundant compounds and AMPK/mTOR. Rat OAS models were established by combined GTW, adrenaline, and ice-water immersion. Pharmacodynamic effects were evaluated through general status, reproductive organ weights, sperm quality, coagulation parameters, and serum sex hormones. Testicular histopathology, ultrastructure, and autolysosomes were examined by HE staining and TEM. Apoptosis was detected by TUNEL staining, and autophagy/apoptosis-related protein expression by IHC. Integrated metabolomics and proteomics with KEGG enrichment were conducted. In GTW-injured GC-1spg cells treated with Compound C or rapamycin, CCK-8 assay assessed viability, flow cytometry evaluated apoptosis, immunofluorescence examined LC3B/cleaved caspase-3 expression and colocalization, and Western blotting/RT-qPCR validated AMPK/mTOR pathway key molecules. Among 307 identified compounds (mostly flavonoids), YSTLF improved general status, organ weights, and sperm quality in model rats. The ten most abundant compounds showed binding energies < -7.0\u202fkcal/mol for AMPK/mTOR. Sperm concentration and motility increased dose-dependently. PT and TT were prolonged, FIB decreased, and FSH, LH, T, PRL, and Inh-B were restored. H&E, TEM, and TUNEL revealed alleviated testicular pathology, improved ultrastructure, reduced autolysosomes, and decreased apoptosis. IHC showed downregulated Beclin1 and Bax, and upregulated p62 and Bcl-2. Multi-omics revealed co-enrichment of differential proteins/metabolites in autophagy and mTOR pathways. Western blot/RT-qPCR validated downregulated p-AMPK/AMPK, AMPK mRNA, LC3II, Beclin1, Bax, cleaved caspase-3, and cleaved caspase-3/caspase-3 ratio, alongside upregulated p-mTOR/mTOR, mTOR mRNA, p62, and Bcl-2. In vitro, GTW reduced viability concentration-/time-dependently (stable model: 10%/24\u202fh); YSTLF reversed this (optimal: 15%/24\u202fh), restored viability, reduced apoptosis, and decreased LC3B/cleaved caspase-3 fluorescence/colocalization, while downregulating p-AMPK, LC3II, Bax and upregulating p-mTOR, p62, Bcl-2. Compound C alone mimicked YSTLF's effects without additivity, whereas rapamycin aggravated GTW-induced viability loss, apoptosis, and autophagy/apoptosis co-activation. YSTLF improved spermatogenic function in rats with OAS (kidney deficiency and collateral obstruction pattern). Its mechanism of action involves regulation of the AMPK/mTOR signaling pathway and restoration of the balance between autophagy and apoptosis.",

Cultured RAW264.7 cells were pretreated with, different concentrations of BBP, or dexamethasone (Dex) for 1 h before LPS challenge. Sixty male C57BL/6 mice were randomized into 5 groups (n=12), including a control group, a LPS-induced ALI model group, a Dex treatment group, and two BBP treatment groups treated with low- (30 mg/kg) or high-dose (120 mg/kg) BBP. The levels of inflammatory factors and oxidative stress-related indicators in the cells and mouse lung tissues were determined, and mouse lung histopathology, wet/dry weight ratio, and BALF cell count were examined; the expressions of NF-\u03baB and Nrf-2/HO-1 pathways were detected using qPCR, Western blotting, and immunohistochemistry. In LPS-stimulated RAW264.7 cells, BBP (12.5 \u03bcg/mL) significantly reduced the levels of TNF-\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, NO and ROS, enhanced SOD activity, increased mRNA expressions of I\u03baB-\u03b1, Nrf-2, and HO-1, and lowered mRNA expressions of TNF-\u03b1, IL-1\u03b2, Keap-1, and NF-\u03baB (p65). The ALI mouse models showed severe lung pathologies and edema, increased BALF cell counts, and increased levels of TNF\u2011\u03b1, COX-2, IL-1\u03b2, IL-6, MDA, and NO, lowered SOD activity with reduced protein expressions of I\u03baB-\u03b1, Nrf-2, and HO-1 and increased expressions of Keap-1 and p65. Treatment with high-dose BBP significantly ameliorated lung pathologies in the mouse models and improved the aberrant alterations in pulmonary expressions of inflammatory factors, oxidative stress-related indicators and the NF-\u03baB and Nrf-2/HO-1 pathways. BBP protects against LPS-induced ALI in mice possibly by targeting the Nrf-2/HO-1 and NF-\u03baB pathways, suggesting its potential as a therapeutic agent for ALI. \u76ee\u7684: \u63a2\u7a76\u718a\u80c6\u7c89\uff08BBP\uff09\u901a\u8fc7\u8c03\u63a7NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u5bf9\u8102\u591a\u7cd6\u8bf1\u5bfc\u7684\u6025\u6027\u80ba\u635f\u4f24\uff08ALI\uff09\u5c0f\u9f20\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u4f53\u5916\u5b9e\u9a8c:\u91c7\u7528\u8102\u591a\u7cd6\uff08LPS\uff09\u8bf1\u5bfcRAW264.7\u7ec6\u80de\u5efa\u7acb\u4f53\u5916\u6a21\u578b\uff0c\u8bbe\u7f6e\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001\u5730\u585e\u7c73\u677e\uff08Dex\uff0c25 \u03bcg/mL\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff086.25 \u03bcg/mL\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff0812.5 \u03bcg/mL\uff09\u3002\u4f53\u5185\u5b9e\u9a8c:\u5c0660\u53eaC57BL/6\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u5bf9\u7167\u7ec4\u3001\u6a21\u578b\u7ec4\u3001Dex\u7ec4\uff085 mg/kg\uff09\u3001BBP\u4f4e\u5242\u91cf\u7ec4\uff0830 mg/kg\uff09\u548cBBP\u9ad8\u5242\u91cf\u7ec4\uff08120 mg/kg\uff09\uff0c12\u53ea/\u7ec4\u3002\u901a\u8fc7ELISA\u548c\u76f8\u5173\u8bd5\u5242\u76d2\u68c0\u6d4b\u7ec6\u80de\u548c\u80ba\u7ec4\u7ec7\u4e2d\u708e\u75c7\u4e0e\u6c27\u5316\u5e94\u6fc0\u6307\u6807;\u901a\u8fc7\u80ba\u7ec4\u7ec7\u75c5\u7406\u5206\u6790\u3001\u514d\u75ab\u7ec6\u80de\u8ba1\u6570\u548c\u80ba\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u7b49\u6307\u6807\u8bc4\u4ef7BBP\u5bf9ALI\u7684\u5e72\u9884\u4f5c\u7528\u3002\u901a\u8fc7qRT-PCR\u3001Western blotting\u548c\u514d\u75ab\u7ec4\u5316\u6cd5\u5206\u6790NF-\u03baB\u548cNrf-2/HO-1\u4fe1\u53f7\u901a\u8def\u76f8\u5173\u86cb\u767d\u4e0e\u57fa\u56e0\u7684\u8868\u8fbe\u53d8\u5316\u3002\u7ed3\u679c: \u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\u7ec4\uff0812.5\u03bcg/mL\uff09\u663e\u8457\u964d\u4f4eTNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u4e00\u6c27\u5316\u6c2e\uff08NO\uff09\u548c\u6d3b\u6027\u6c27\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff0c\u4e14I\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff0c\u800cTNF-\u03b1\u3001IL-1\u03b2\u3001Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684mRNA\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff08P<0.05\uff0cP<0.01\uff0cP<0.001\uff09\u3002\u52a8\u7269\u5b9e\u9a8c\u7ed3\u679c\u663e\u793a\uff0c\u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u7ed3\u6784\u7d0a\u4e71\uff0c\u80ba\u6ce1\u58c1\u589e\u539a\uff0c\u80ba\u6ce1\u5185\u53ef\u89c1\u5927\u91cf\u708e\u75c7\u7ec6\u80de\u6d78\u6da6\uff0c\u80ba\u7ec4\u7ec7\u6e7f/\u5e72\u8d28\u91cf\u6bd4\u53ca\u652f\u6c14\u7ba1\u80ba\u6ce1\u704c\u6d17\u6db2\uff08BALF\uff09\u603b\u7ec6\u80de\u6570\u5347\u9ad8\uff08P<0.01\uff09;\u80ba\u7ec4\u7ec7\u4e2d\u7684TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u542b\u91cf\u5347\u9ad8\uff0c\u800cSOD\u6d53\u5ea6\u964d\u4f4e\uff08P<0.01\uff0cP<0.001\uff09;\u4e14\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u964d\u4f4e\uff0cKeap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u76f8\u6bd4\uff0cBBP\uff08120 mg/kg\uff09\u7ec4\u80fd\u6539\u5584\u5c0f\u9f20\u80ba\u7ec4\u7ec7\u75c5\u7406\u635f\u4f24\u72b6\u6001\uff0c\u6539\u5584\u80ba\u80bf\u80c0\u7a0b\u5ea6\uff0c\u964d\u4f4eBALF\u603b\u7ec6\u80de\u6570\u3001TNF-\u03b1\u3001COX-2\u3001IL-1\u03b2\u3001IL-6\u3001MDA\u548cNO\u6c34\u5e73\uff0c\u5347\u9ad8SOD\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09;\u540c\u65f6\uff0cBBP\u4e0a\u8c03\u4e86\u80ba\u7ec4\u7ec7\u4e2dI\u03baB-\u03b1\u3001Nrf-2\u548cHO-1\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u5e76\u6291\u5236\u4e86Keap-1\u548cNF-\u03baB\uff08p65\uff09\u7684\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff08P<0.05\uff0cP<0.01\uff09\u3002\u7ed3\u8bba: BBP\u53ef\u80fd\u901a\u8fc7\u4f5c\u7528\u4e8eNrf-2/HO-1\u548cNF-\u03baB\u4fe1\u53f7\u901a\u8def\u5bf9LPS\u8bf1\u5bfc\u7684ALI\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u540e\u7eed\u7814\u7a76\u6f5c\u5728\u7684\u6cbb\u7597ALI\u836f\u7269\u63d0\u4f9b\u4f9d\u636e\u3002.",
"42488829": "ID: 42488829\nTitle: Challenges and opportunities for ginseng-based medicines in treating cardiac fibrosis from mechanistic insights to clinical translation.\nAbstract: Cardiac fibrosis, characterized by excessive extracellular matrix (ECM) deposition and progressive myocardial remodeling, is a common pathological outcome of various cardiovascular diseases and lacks effective targeted anti-fibrotic therapies. Panax ginseng and its related preparations, including major ginsenosides (e.g., Rb1, Rg1, and Rg3), standardized extracts, and compound formulas, have garnered growing interest owing to their multi-component, multi-target pharmacological activities and integrative regulatory effects. This review systematically summarizes recent advances in the basic and clinical research of ginseng-based medicines in the prevention and treatment of cardiac fibrosis. Preclinical evidence demonstrates that ginseng and its active constituents attenuate key pathological processes, including oxidative stress, inflammatory responses, apoptosis, and autophagy dysregulation, primarily through modulation of signaling pathways such as TGF-\u03b2/Smad, NF-\u03baB, and PI3K/Akt. These regulatory effects collectively contribute to the inhibition of fibroblast activation, reduction of collagen deposition, and improvement of myocardial structure and function. Emerging clinical studies further suggested potential benefits in improving cardiac function and modulating fibrosis-related biomarkers in patients with hypertension, coronary heart disease, and heart failure (HF). Despite these promising findings, several challenges hinder clinical translation, including low oral bioavailability, the mechanistic complexity of compound formulas, and insufficient high-quality clinical evidence. Future investigations should integrate novel drug delivery strategies, systems pharmacology approaches to elucidate holistic mechanisms, and well-designed randomized controlled trials to facilitate the development of ginseng-based medicines as potential therapeutic agents for cardiac fibrosis.",
"42491593": "ID: 42491593\nTitle: The role of endoplasmic reticulum stress-mediated autophagy in cadmium-induced liver injury in rats.\nAbstract: Cadmium (Cd) is a widespread toxicant with high bioaccumulation potential. This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage.",
"42492603": "ID: 42492603\nTitle: Neonatal propofol exposure induces region-specific neurotoxic proteomic signatures in mouse cortex and hippocampus.\nAbstract: Neonatal propofol exposure has been implicated in long-term neurodevelopmental impairments; however, region-specific molecular mechanisms remain unclear. This study examined region-specific proteomic alterations in exosome-enriched small extracellular vesicles (exosome-enriched sEVs) from the cortex and hippocampus induced by neonatal propofol exposure. Using a clinically relevant repeated-dose regimen, C57BL/6 mice received propofol (50\u00a0\u00a0mg/kg, P5-P7). At P21, exosome-enriched sEVs were isolated and analyzed by data-independent acquisition mass spectrometry. Candidate differentially expressed proteins (candidate DEPs) were defined by fold change (FC)\u00a0\u2265\u00a01.5 or\u00a0\u2264\u00a00.667 and nominal p\u00a0<\u00a00.05, followed by Gene Ontology (GO), KEGG pathways, Cluster of Orthologous Groups (COG), and domain enrichment analyses. After Benjamini-Hochberg correction, no protein reached q\u00a0<\u00a00.05, indicating that the exploratory findings were not significant. We identified 63 candidate DEPs in the hippocampus and 55 in the cortex. Hippocampal downregulated proteins enriched in synaptic vesicle cycling, oxidative phosphorylation, and apoptosis, suggesting synaptic-mitochondrial disruption; upregulated proteins associated with ER stress and chaperone-mediated autophagy, suggesting proteostatic adaptation. Cortical candidate DEPs reflected suppressed mitochondrial function alongside enhanced translation and cytoskeletal remodeling. These region- and direction-specific changes were consistently observed across all bioinformatic platforms. The hippocampus showed pronounced synaptic and mitochondrial alterations, while the cortex exhibited cytoskeletal changes and metabolic shifts. In conclusion, Propofol induces distinct neurotoxic proteomic signatures in the neonatal hippocampus and cortex, suggesting compartment-specific vulnerability and compensatory remodeling. Thus, exosome-enriched sEV proteomics offers a sensitive approach to detecting early anesthetic-induced neurodevelopmental disturbances.",
"42492605": "ID: 42492605\nTitle: Exosomes from bone marrow mesenchymal stem cells inhibit osteoclast differentiation and alleviate osteoporosis via RBM15B/YAP1 to induce autophagy.\nAbstract: Osteoporosis develops primarily as a result of an imbalance between osteoclastic bone resorption and osteoblastic bone formation. Bone marrow mesenchymal stem cells-derived-exosomes (BMSCs-Exos) regulate osteoclast differentiation and osteoporosis in recent studies. But the mechanisms are still unclear. This research aimed to explore the mechanisms of BMSCs-Exos in osteoclast differentiation and osteoporosis. Exosomes were extracted from BMSCs. THP-1\u202fcells were cultured and treated with BMSCs-Exos. Osteoclast- and autophagy-related gene expression was assessed by qPCR and Western blot, the regulation of YAP1 by RBM15B was analyzed by MeRIP and RNA pull-down, osteoclast differentiation was detected by TRAP staining. HE staining, immunohistochemical staining and micro-CT were employed to assess the impact of BMSCs-Exos on osteoporosis. BMSCs-Exos were internalized by THP-1\u202fcells, promoted YAP1 expression and autophagy, and inhibited osteoclast differentiation. Silencing of YAP1 in THP-1\u202fcells reversed BMSCs-Exos-induced autophagy and the inhibition of osteoclast differentiation; conversely, YAP1 overexpression produced opposite effects. BMSCs-Exos-delivered RBM15B promoted m6A methylation modification of YAP1. Silencing of RBM15B in BMSCs blocked the impact of BMSCs-Exos on autophagy and osteoclast differentiation, whereas RBM15B overexpression exerted opposing influences. Furthermore, BMSCs-Exos suppressed osteoclast differentiation and alleviated osteoporosis in vivo through RBM15B/YAP1 mediated autophagy. BMSCs-Exos promoted m6A methylation modification of YAP1 by delivering RBM15B mRNA to enhance YAP1 RNA stability, promoted autophagy, and inhibited osteoclast differentiation and alleviated osteoporosis.",
"42501555": "ID: 42501555\nTitle: Gut microbiota and polycystic ovary syndrome: Pathogenesis and novel therapeutic approaches.\nAbstract: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women that is characterized by a complex pathogenesis involving multiple mechanisms, including hyperandrogenism, ovulatory dysfunction, insulin resistance (IR), and chronic inflammation. Recent studies have demonstrated that the gut microbiota acts as an important metabolic regulator and may play a pivotal role in the onset and progression of PCOS. Patients with PCOS frequently exhibit gut microbiota dysbiosis, which is characterized by reduced microbial diversity, decreased levels of beneficial bacteria, increased levels of pathogenic bacteria, and altered metabolic byproducts. This imbalance may contribute to IR and ovarian dysfunction by activating the toll-like receptor 4/nuclear factor kappa B inflammatory pathway, inducing oxidative stress, and disrupting Wnt/\u03b2-catenin signaling. The Wnt/\u03b2-catenin signaling pathway, a key regulator of follicular development, is frequently aberrantly activated in PCOS. In this narrative review, we summarize the recent advances in understanding the roles of the gut microbiota and the Wnt/\u03b2-catenin signaling pathway in the pathogenesis of PCOS. To this end, we conducted a comprehensive literature search across PubMed, Web of Science, Embase, and Cochrane Library databases, covering publications from January 2012 to March 2026. Ninety-eight articles were included after screening. We further explored therapeutic strategies based on microbiome modulation and signaling pathway targeting, including probiotics, traditional Chinese medicine, ginsenosides, puerarin, fecal microbiota transplantation, and nanoparticle-based ginseng-derived exosomes, thereby providing novel insights into potential therapies for PCOS.",
"42503062": "ID: 42503062\nTitle: Integrated miRNA-mRNA-degradome analysis unveils the key regulatory mechanism of ginseng under temperature-water stress.\nAbstract: MYB and bHLH are the key transcription factors to coordinate the balance between antioxidant system and secondary metabolism under combined temperature-water stress. Low temperature and drought severely impede medicinal plant growth and secondary metabolite accumulation. Identifying key regulatory genes or modules and clarifying their molecular mechanisms is critical for advancing the ginseng industry. Using ginseng hairy roots, we established a composite stress system combining 5\u00a0\u00b0C with 10-30% polyethylene glycol. We assessed effects on ginseng hairy roots growth, ginsenoside content, and stress-related physiological responses, and performed miRNA, transcriptome, and degradome sequencing analysis. Low-temperature and mild-drought (LTD) treatment significantly promoted ginsenoside accumulation, peaking on day 8, and enhanced antioxidant enzyme activity, indicating robust stress tolerance. Co-analysis identified four miRNAs, mtr-MIR159a-p3_2ss16GT17CT_1, mtr-MIR159a-p3_2ss16GT17CT_2, ptc-miR319a_L\u2009+\u20091R-1, and stu-miR482c_2ss12AT18GA that target MYB and bHLH transcription factor family and exhibit negative expression correlations. These miRNAs likely act as central regulators of ginsenoside biosynthesis under combined temperature-water stress, providing mechanistic insights into how ecological factors modulate ginsenoside production.",
"42507332": "ID: 42507332\nTitle: Disease mechanisms and translational barriers guide nanocarrier design for nose to brain delivery in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder with limited disease-modifying treatment options, partly because many therapeutic agents show insufficient brain exposure and dose-limiting systemic adverse effects after conventional administration. Nose-to-brain (N2B) delivery has emerged as a non-invasive strategy to transport therapeutics to the central nervous system through the olfactory and trigeminal pathways, thereby partially bypassing the blood-brain barrier. Recent advances in nanomedicine and biomaterial engineering have further improved this approach by enhancing drug stability, nasal residence, mucosal transport, and brain-targeting efficiency. This review examines nanocarrier-enabled N2B delivery strategies for AD from a mechanism-guided perspective, highlighting how AD-related pathological processes shape the selection of therapeutic cargos and formulation designs. We discuss recent progress in the intranasal delivery of repurposed small molecules, natural products, insulin-related agents, peptides and proteins, extracellular vesicles, antibodies, and nucleic acid-based therapeutics. We further summarize major nanocarrier and formulation platforms, including lipid-based systems, polymeric nanoparticles, micelles, extracellular vesicles, in situ gels, and device-assisted delivery technologies. Particular attention is given to the design parameters that influence N2B performance, including particle size distribution/PDI, surface charge, mucus interaction, cargo protection, targeting modification, biodistribution, and deposition reproducibility. Finally, we critically evaluate the translational challenges that continue to limit clinical application, including species differences in nasal anatomy, dose-volume restrictions, device-dependent variability, limited human pharmacokinetic evidence, manufacturing complexity, long-term safety, and regulatory requirements. By integrating disease mechanisms, nanocarrier design, and translational considerations, this review provides a structured perspective for developing more rational and clinically feasible N2B nanodelivery systems for AD.",

Endoplasmic reticulum stress (ERS) and autophagy are implicated in its pathogenesis, but the precise mechanisms remain unclear. This study aimed to identify ERS and autophagy-related key genes (ERS-RGs and ARGs) in MCD using bioinformatic and experimental approaches. Methods: Transcriptomic data from GSE216841 and GSE246206 were analyzed. ERS-RGs and ARGs were obtained from prior literature. Candidate genes were selected by integrating weighted gene coexpression network analysis and differential expression analysis. Feature genes were identified via protein-protein interaction network analysis and machine learning (Least Absolute Shrinkage and Selection Operator and Boruta). Key genes were validated by expression analysis and receiver operating characteristic evaluation. A multilayer perceptron (MLP) model was constructed, and regulatory networks, immune infiltration, and chemical compound prediction were analyzed. The expression levels of the identified key genes were preliminarily assessed in peripheral blood samples using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Results:LIG4 and ZRANB3 were identified as key genes, both significantly downregulated in the MCD group, and the gene-based MLP model effectively predicted MCD probability. Overall, 13 significantly different immune cell types (e.g., CD56+ natural killer and activated dendritic cells) were detected. Regulatory networks (transcription factor-messenger RNA (mRNA) and long non-coding RNA-microRNA-mRNA) and 8 common chemical compounds (e.g., bisphenol A, acetaminophen) targeting these genes were predicted. Notably, peripheral blood RT-qPCR analysis revealed significant LIG4 and ZRANB3 downregulation, suggesting a systemic expression signature. Conclusions:LIG4 and ZRANB3 are key genes associated with ERS and autophagy in MCD, providing insights for diagnosis and targeted therapy.",

Methods: We applied genomic structural equation modeling to European-ancestry GWAS summary statistics for five constituent phenotypes: depressive symptoms, depression diagnosis, grip strength, appendicular lean mass, and walking pace. A Depression-Physical Function shared genetic factor was constructed as a cross-trait genetic covariance dimension and evaluated using LDSC-based validation and leave-one-trait-out sensitivity analyses. We then performed factor GWAS, FUMA locus annotation, Bayesian fine-mapping, MAGMA gene-based analysis, transcriptome-wide association analysis, pathway enrichment, CELLECT/MAGMA cell-type specificity analysis, partitioned heritability analysis, and gsMap spatial transcriptomic mapping. Results: The shared factor showed good model fit and retained 755,397 quality-controlled variants for downstream analysis. The factor was positively genetically correlated with depression-related traits and negatively correlated with physical-function-related traits. FUMA identified 245 genome-wide significant SNPs, 44 lead SNPs, and 38 genomic risk loci, with 127 positional mapped genes. Fine-mapping prioritized one high-confidence locus. MAGMA identified 19 Bonferroni-significant genes and 326 FDR-significant genes, while TWAS identified 322 FDR-significant expression-associated genes. Integrating FUMA positional mapping, MAGMA gene-level association and TWAS expression-level association prioritized eight convergent genes: TMEM106B, CENPW, DRD2, LRFN5, NCAPG, DCAF16, SGIP1, and FAM120A. Functional enrichment highlighted postsynaptic structure, neuron spine, synaptic plasticity, and synapse organization. CELLECT/MAGMA prioritized brain non-myeloid neurons and glial populations, with additional endocrine-metabolic and immune-hematopoietic signals. Spatial transcriptomic mapping localized top signals to brain and spinal cord regions in the embryonic neuro-muscle reference. Partitioned heritability analysis showed enrichment in conserved, intronic, promoter, and chromatin-related genomic annotations. Conclusions: These findings support a shared polygenic covariance dimension linking depression-related liability with reduced physical-function-related genetic propensity. Downstream analyses prioritized candidate loci, genes, and biological contexts, with enrichment patterns consistent with neuronal, synaptic, and regulatory genomic processes.",
"42511092": "ID: 42511092\nTitle: Role of Autophagy in Goose Astrovirus-Induced Renal Injury in Goslings.\nAbstract: Goose astrovirus (GoAstV) is a newly identified virus affecting geese, leading to goose gout, which is marked by urate deposits in organs and joints. This research investigates the role of autophagy in renal damage caused by GoAstV in goslings. The findings indicated that GoAstV infection in goslings resulted in characteristic clinical manifestations, with renal tissues displaying tubular swelling, inflammatory infiltration, and autophagosome formation. In vivo experiments demonstrated a significant upregulation of mRNA levels for autophagy-related factors, including AMPK, LC3A, ATG5, ATG7, P62, Beclin1, AMBRA1 and GABARAPL1, while mTOR and LC3B levels were notably decreased. At 3 dpi, the protein expression levels of ATG5, Beclin1, and LC3B II/I increased, while P62 levels decreased, suggesting autophagy activation. In vitro analyses revealed that GoAstV infection led to enhanced autophagy; however, the concurrent upregulation of LC3B II/I and P62 proteins suggested an obstruction in the autophagic flux. Upon the inhibition of autophagy with 3-methyladenine (3-MA, autophagy inhibitor), there was a significant reduction in the expression of autophagy-related factors, accompanied by a marked decrease in viral replication rates. In conclusion, GoAstV infection in gosling kidney cells initially triggers enhanced autophagy and subsequently causes a blockage in the autophagic flux. The virus exploits autophagosomes for replication, ultimately resulting in kidney damage. The application of 3-MA effectively inhibits this autophagic process and diminishes viral replication.",

Exosomes derived from adipose-derived mesenchymal stem cells (ADMSC-Exo) have robust protective effects under non-otologic ischemic conditions. However, their otoprotective effects remain unclear. This study aimed to investigate the protective effects of human ADMSC-Exo against cochlear damage and mitochondrial dysfunction under oxygen-glucose deprivation (OGD), an in vitro and ex vivo model of cochlear ischemia. ADMSC-Exo attenuated OGD-induced cytotoxicity and apoptosis in HEI-OC1 cells and reduced the OGD-induced loss of cochlear hair cells in the organ of Corti explants. OGD caused a decrease in mitochondrial mass and mitochondrial membrane potential depolarization and impaired mitochondrial respiration in auditory cells. ADMSC-Exo preserved mitochondrial integrity and improved mitochondrial bioenergetic function following OGD exposure. These effects were accompanied by increased LC3-II conversion and formation of autolysosome-like structures and elevated expression of PINK1 and Parkin, indicating the activation of autophagy and mitophagy-related protective mechanisms. Importantly, 3-methyladenine, an autophagy inhibitor, attenuated the cytoprotective effect of ADMSC-Exo, supporting the involvement of autophagy in ADMSC-Exo-mediated protection. Collectively, these findings suggest that ADMSC-Exo protect against OGD-induced cochlear injury by promoting autophagy-associated mitochondrial protection.",

It is characterized by diverse cellular morphology, unusual growth patterns, and a propensity for local tumor recurrences. A 76-year-old patient underwent multiple surgical removals of MFS recurrences of the thoracic cavity and surrounding tissues with the subsequent development of metastases. Single-cell RNA sequencing was used to analyze the earlier (R7) and later (R8) MFS recurrences, with R8 removed less than a year before the detection of metastases in the lungs. The earlier MFS recurrence displays tumor clusters with multiple immunomodulatory markers (DKK1, APP, CD24, GRN) and genes involved in lipid metabolism and cell stress (DDIT3, ABCA1, ABCA10, ATF4, NEU1), combined with an anti-inflammatory TME. The later MFS recurrence shifts to a functionally less diverse phenotype, enriched in fibroblast-typical markers (POSTN, NES, COL1A1/A2), and a pro-inflammatory TME. The proliferative (MKI67, TOP2A, BUB1B) and mRNA splicing and processing (SNRNP70, SRSF2/5/11, RSRP1, LUC7L/7L3, SRRM1/2) tumor clusters are observed in both MFS recurrences, and their signatures match the previous data on primary MFS tumor populations. ScRNA-seq analysis of two subsequent MFS recurrences from one patient show a change from functionally diverse to more uniform ECM remodeling enriched tumor populations, an accompanying shift to the pro-inflammatory TME, and the presence of two common tumor clusters enriched in proliferative and mRNA-processing gene signatures.",
"42511591": "ID: 42511591\nTitle: Intracellular Crosstalk of the Gasotransmitter Trio (NO, CO, H2S) in Cardiovascular Health and Disease: From Molecular Signaling to Precision Gas Medicine.\nAbstract: Nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S) were once regarded solely as toxic environmental gases. However, accumulating evidence over the past several decades has established them as the three principal endogenous gasotransmitters that regulate a wide spectrum of physiological and pathological processes. Unlike conventional signaling molecules, gasotransmitters diffuse freely across biological membranes and exert potent biological effects through receptor-independent mechanisms, including redox-sensitive post-translational modifications and modulation of heme-containing proteins. Although the individual functions of NO, CO, and H2S have been extensively reviewed, emerging studies indicate that these gaseous mediators rarely operate in isolation. Instead, they form a highly integrated signaling network characterized by direct chemical interactions, reciprocal enzymatic regulation, and convergence upon common downstream pathways. In this mini-review, we propose the concept of a \"Gasotransmitter Trio Network,\" emphasizing the molecular crosstalk among NO, CO, and H2S as a fundamental determinant of cellular homeostasis. We first summarize the biosynthetic pathways and major signaling mechanisms of the gasotransmitter trio, including S-nitrosylation, persulfidation, and heme-dependent regulation. We then discuss recent advances revealing how interactions among these gases generate novel bioactive intermediates and coordinate redox signaling. Particular attention is given to the emerging roles of gasotransmitters in regulating ferroptosis, autophagy, and mitophagy by modulating iron metabolism, lipid peroxidation, mitochondrial quality control, and antioxidant defense systems. These findings support a unified framework in which gasotransmitters function as master regulators of cellular fate under conditions of physiological and pathological stress. Finally, we highlight recent progress in stimuli-responsive donors, CO-releasing molecules (CORMs), NO-releasing materials (NORMs), H2S donors, and advanced nanoplatforms that enable spatiotemporally controlled gas delivery. We propose that future therapeutic strategies will increasingly rely on programmable multi-gas systems that recapitulate endogenous gasotransmitter networks. Collectively, this review provides a systems-level perspective on gasotransmitter biology and outlines emerging opportunities for the development of precision gas medicine in cardiovascular, neurodegenerative, inflammatory, metabolic, and malignant diseases.",

Moreover, we discuss the potential role of TMEM106B as an important modifier of the protein TDP-43 neuropathology associated with the GRN mutation in this case. The patient underwent detailed clinical assessment, serial neuropsychological evaluation, brain MRI, cerebrospinal fluid analysis, whole-exome sequencing, and next generation sequencing. A postmortem neuropathologic examination was performed to confirm the diagnosis. The patient presented slowly progressive paresthesia, cerebellar ataxia, dysarthria, and later cognitive and behavioral changes. Genetic testing revealed a heterozygous PRNP P102L variant and an unpenetrated GRN p.R110X variant; a protective TMEM106B polymorphism associated with TDP-43 pathology was also identified. Neuroimaging demonstrated progressive cerebellar and parietal atrophy with asymmetric left frontal opercular and insular involvement. The clinical course was dominated by a cerebellar GSS phenotype. The patient died 4 years after symptom onset. Neuropathology confirmed GSS, nevertheless without detectable TDP-43-associated neuropathology. This case highlights the diagnostic complexity of rare neurodegenerative disorders and illustrates that pathogenic variants may not influence phenotypic expression. Comprehensive genetic testing should be considered in atypical cases, as certain genetic variants may contribute to phenotypic variability and represent potential modifiers of phenotypic expression.",
"42517186": "ID: 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.",

However, their role in the challenging chronic inflammatory type 2 diabetes (T2D) fracture healing remains unclear. In this study, we investigated the effect of Mg-IMN on fracture healing in a T2D mouse model and explored the involvement of regulatory T cells (Tregs) in this process. Our results demonstrated that Mg-IMN promotes fracture healing in Leprdb/db T2D mice. At 5 days post-fracture, flow cytometry showed an increased number of Tregs in the fracture callus. Notably, depletion of Tregs via injection of PC61 neutralizing antibody abolished the promotive effect of Mg-IMN, indicating the critical role of Tregs in this process. Bulk RNA sequencing of the bone callus at 5 days post-fracture revealed significant enrichment of pathways related to chemokine signaling and CCR chemokine receptor interactions, suggesting a mechanism of Treg recruitment. Transwell migration assays in vitro preliminarily indicated the chemotactic effect of CCL19 and CCL21 in recruiting Tregs. Furthermore, Mg2+ treatment enhanced the mRNA expression levels of amphiregulin (Areg) and granulin (Grn) in Tregs, as indicated by qRT-PCR analysis. These findings may pave the way for new applications of Mg-IMN in fracture repair and provide unique insights into osteoimmunology during the complex process of T2D fracture healing.",
"42518684": "ID: 42518684\nTitle: Nanoparticles Navigating the Blood-Brain Barrier for Neurodegenerative Therapy.\nAbstract: The blood-brain barrier (BBB) blocks most drugs from entering the brain. Over 98% of small-molecule drugs and nearly all biologics fail to cross this barrier. Nanoparticles (NPs) provide multiple ways to bypass the BBB. These include receptor-mediated transcytosis, adsorptive-mediated transport, and intranasal delivery. NPs can also modify disease-related pathways. For example, they promote amyloid-\u03b2 clearance, reduce tau phosphorylation, and reprogram neuroimmune responses. Many preclinical studies have shown promising results in Alzheimer's, Parkinson's, and Huntington's diseases. However, no NP-based therapy has moved beyond early-stage clinical trials. Several issues remain unresolved. Direct comparisons between different NP platforms are lacking. The long-term toxicity of NPs in the brain is not well understood. Animal models also do not accurately reflect human disease. We suggest that future work should focus on standardized characterization, better predictive models, and clinical trial designs that address NP diversity. Researchers should also compare NP therapies with existing treatments in a rigorous manner.",

We applied integrated metagenomics and metabolomics to characterize gut microecology in 28 patients with AD and 33 controls. Metagenomic analysis revealed distinct microbial community structures, with increased abundance of Akkermansia massiliensis, Alistipes onderdonkii, and Barnesiella intestinihominis in AD. Phageome analysis revealed increased richness and altered composition, with more Podoviridae and fewer Microviridae. Functional profiling identified shifts in microbial metabolic pathways involving tryptophan and short-chain fatty acid metabolism. Untargeted metabolomics revealed elevated fecal spermidine, taurocholate, and glycerophosphocholine levels in patients with AD. A random forest model combining metabolites, gut metabolic modules, and bacteriophages achieved good within-cohort classification (AUC = 0.83) but lacked external validation due to unavailable matched fecal metabolomic data. Overall, these findings link AD to coordinated disruptions across bacterial, viral, and metabolic gut layers, highlighting the need for external validation and mechanistic studies.",
"42520681": "ID: 42520681\nTitle: PNPT1-induced mitochondrial dysfunction drives osteoclast activation via post-transcriptional Nrf2 suppression and lipid peroxidation signaling.\nAbstract: Polynucleotide phosphorylase 1 (PNPT1) functions as a crucial mitochondrial enzyme; nevertheless, its potential genetic correlation with osteoporosis and its specific regulatory impact on osteoclastogenesis remain to be elucidated. We executed a two-sample Mendelian randomization (MR) strategy to interrogate the causal link connecting PNPT1 expression to osteoporosis risk. For in vivo substantiation, we utilized both an ovariectomized (OVX) murine model and an adeno-associated virus (AAV)-driven overexpression system. Extensive in vitro assays employing RANKL-stimulated RAW264.7 macrophages were conducted to evaluate osteoclast differentiation, mitochondrial dynamics, autophagic flux, and intracellular oxidative stress through molecular and morphological analyses. MR evaluations pinpointed genetically predicted elevated PNPT1 expression as a potential genetic risk factor for osteoporosis. In vivo observations revealed a significant surge of PNPT1 within the osteoclast precursors of OVX subjects. In vitro, the ectopic overexpression of PNPT1 significantly enhanced osteoclastogenesis and bone degradation while simultaneously triggering severe mitochondrial depolarization alongside the accumulation of reactive oxygen species (ROS). On the contrary, targeted Pnpt1 silencing markedly suppressed osteoclast maturation. Mechanistic probes demonstrated that PNPT1 disrupted autophagic flux, marked by p62 accumulation. Notably, even with a compensatory transcriptional rise in Nrf2 mRNA, PNPT1 overexpression provoked a marked downregulation of Nrf2 and xCT proteins, suggesting a potent post-transcriptional suppression of the cellular antioxidant shield. This uncoupling invariably precipitated sub-lethal lipid peroxidation that amplifies osteoclastogenic signaling. Concordantly, AAV-mediated systemic PNPT1 amplification aggravated trabecular bone deterioration in vivo. Guided by our MR findings and validated through our functional models, PNPT1 emerges as a potential genetic risk factor for osteoporosis. By inciting mitochondrial damage, provoking ROS buildup, and decoupling the protective autophagy-Nrf2/xCT axis, PNPT1 promotes osteoclastogenesis, thereby introducing a promising immunopharmacological target for restraining pathological bone resorption.",
"42520939": "ID: 42520939\nTitle: SNX-BAR proteins 5 and 6 are required for NCOA7-AS antiviral activity against influenza A virus.\nAbstract: Interferon-induced antiviral proteins act on the first line of defence against viruses, including influenza A virus (IAV). Among those, the short isoform of Nuclear Receptor Coactivator 7 (NCOA7-AS) has been shown to inhibit IAV entry and more especially the fusion between endosomal and viral membranes. Ectopic expression of NCOA7-AS leads to the increased acidification of the endolysosomal pathway, putatively through NCOA7-AS interaction with the vacuolar ATPase (V-ATPase). However, the precise mechanism of action of NCOA7-AS is not fully understood. Here, we identified the cellular partners of NCOA7-AS by mass spectrometry, including the V-ATPase subunits known to interact with NCOA7-AS. A point mutation disrupting the interaction with the V-ATPase led to loss of antiviral activity against IAV, demonstrating that V-ATPase engagement is required for the antiviral phenotype. Moreover, sorting nexin (SNX) 1/2/5/6 were identified as novel partners of NCOA7-AS. These proteins are involved in retrograde transport of cellular cargoes from endosomes to the trans-Golgi network. We revealed that SNX5/6 interacted directly with NCOA7-AS and were essential for NCOA7-AS antiviral activity against IAV. Interestingly, crystal structures of NCOA7-AS/SNX5 complexes showed that the SNX5-interaction motif in NCOA7-AS was similar to those found in known cargoes of SNX5/6. In addition, we could pinpoint several critical residues that were important for binding and antiviral activity. Collectively, our study identifies novel essential partners for NCOA7-AS antiviral activity and the structural basis for their interaction.",

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.",

Selenium nanoparticles (Se-NPs) are neuroactive agents owing to their antioxidant and anti-inflammatory activities. Additionally, physical and mental activities (Ph&M) exert neuroprotective effects by optimizing the release of both neurotransmitters and growth factors. However, their neuroprotective effects against SI-induced depression are still poorly investigated. We aim to explore the neuroprotective effect of Se-NPs, Ph&M, and their combination to guard against the harmful effects of SI-induced depression in a rat model. Fifty Sprague Dawley rats were randomly allocated into five groups: control, SI, Ph&M, orally administered Se-NPs (0.1\u00a0mg/kg), and a combination group. Neuroprotective activity was quantitatively estimated pharmacologically, biochemically, histologically, and behaviorally. SI caused behavioral and biochemical alteration in the rat model, decreasing neurotransmitter levels, increasing the transcription of inflammatory response genes (TLR4 and NF-\u03baB), and consequently increasing the production of the cytokines TNF-\u03b1 and IL-1\u03b2. It also activated the proinflammatory NLRP3/caspase-1 pathway. The ER stress parameters PERK, CHOP, and GRP78 were significantly elevated. Impairment of autophagy and increased neurodegeneration were detected via the decline of AMPK/SIRT-1/Beclin-1 PI3K/AKT gene expression and m-TOR overexpression. Decreased expression of TrkB and CREB mRNA and consequent decline in brain-derived neurotropic factor were recorded. SI caused a drastic drop in Wnt3a and \u03b2-catenin levels and increased GSK3\u03b2 activity affecting neuroplasticity and cognitive functions. Administration of Se-NPs and/or application of Ph&M, especially their combination, provided significant protection against prior SI effects. Se-NPs and Ph&M, especially their combination, showed promising protective effects against neuroinflammation, oxidative stress, apoptosis and subsequent alterations of test animal behaviors precipitated by SI.",

Despite advances in antiseizure medications, effective epilepsy management remains challenging because of pharmacoresistance, limited blood-brain barrier (BBB) permeability, inadequate intracerebral drug accumulation, and systemic toxicity. Moreover, currently available therapies primarily provide symptomatic seizure control without addressing the fundamental pathological processes involved in epileptogenesis, neuroinflammation, oxidative stress, and neuronal degeneration. Intranasal administration has emerged as an attractive non-invasive approach for direct brain targeting, enabling therapeutic agents to circumvent BBB-associated transport barriers and access the central nervous system through the olfactory and trigeminal neural pathways. In this context, biodegradable nanomedicine platforms have gained considerable attention due to their favorable biocompatibility, controlled drug release, enhanced mucosal permeation, and potential for targeted intracerebral delivery. This review provides a comprehensive and critical overview of recent advances in intranasal biodegradable nanomedicine for epilepsy, integrating current knowledge on disease pathophysiology, biological and pharmaceutical barriers, nose-to-brain transport mechanisms, biodegradable nanoparticle platforms, and emerging functionalization strategies. Importantly, the review critically evaluates the current evidence, distinguishing encouraging preclinical findings and discusses the major translational challenges that continue to hinder clinical implementation. Finally, future perspectives are highlighted to identify opportunities for developing safer, more effective, and clinically translatable therapies for epilepsy management.",
"42529163": "ID: 42529163\nTitle: The endo-lysosomal-lipid axis: bidirectional interactions between membrane trafficking dysfunction and lipid metabolic disorders.\nAbstract: The endo-lysosomal system is a central regulator of intracellular trafficking, cargo degradation, and metabolic homeostasis. Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities.",

No definitive methods exist to repair damaged neurons. Vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) are two neuroprotective agents that work synergistically. However, these large molecular proteins have difficulty crossing the blood-brain barrier (BBB). Extracellular vesicles (EVs) offer superior targeting and low immunogenicity, making them excellent carriers. In this study we examined the protective effects of VEGF and NGF in a cell model and evaluated the therapeutic potential of VEGF-NGF contained within EVs in PD rats. EVs were isolated using sequential differential centrifugation and characterized using transmission electron microscopy, nanoparticle tracking analysis, and western blotting (WB). VEGF and NGF were loaded into the EVs using a saponin-assisted method to create VEGF@EVs, NGF@EVs, and VEGF/NGF@EVs. The viability of 6-hydroxydopamine hydrochloride (6-OHDA)-induced SH-SY5Y cells was measured using the cell counting kit-8 assay before and after treatment with VEGF and NGF. Autophagy levels were assessed using WB, and the role of autophagy was further explored using the autophagy inhibitor chloroquine. Unilateral PD rat models were established via stereotactic injection of 6-OHDA into male Sprague-Dawley rats. Behavioral changes were monitored before and after treatment. Neuronal recovery, neurotransmitter levels, and autophagy levels in the rat brains were evaluated using immunohistochemistry, enzyme-linked immunosorbent assay, and WB. VEGF/NGF@EVs significantly enhanced the viability of 6-OHDA-induced SH-SY5Y cells. A complete autophagic process was identified as essential for this protective effect. The intranasal administration of VEGF/NGF@EVs improved motor behavior in PD rats, with performance better than that of single growth factor treatments. The number of tyrosine hydroxylase (TH)-positive neurons, TH protein expression, and dopamine content were significantly increased. In addition, the level of autophagy in the rat substantia nigra was elevated. VEGF/NGF@EVs exert protective effects in both in vitro and in vivo 6-OHDA-induced PD models by promoting autophagy, demonstrating greater efficacy than either growth factor alone. By transplanting VEGF/NGF@EVs into PD rats, we showed that these vesicles can effectively cross the BBB and deliver targeted therapy to the central nervous system. This study highlights the significant potential of EV-mediated protein transplantation strategies for treating neurological disorders.",

Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC. Moreover, the combination of NK cell exosomes with DSF/Cu improved the therapeutic effect of DSF/Cu, which helps to promote the targeted therapy of GC and improve clinical applicability.",

In recent years, compounds belonging to the 4H-pyran chemical class have attracted significant attention due to their pronounced antioxidant, anti-inflammatory, and cytoprotective properties. These molecules exhibit structural versatility, enabling modulation of multiple molecular targets involved in neuronal survival, redox homeostasis, and mitochondrial function. This review provides a comprehensive analysis of the pharmacological activity and molecular mechanisms of action of five 4H-pyran-based compounds-maltol, kojic acid, chelidonic acid, comenic acid, and meconic acid. Special attention is paid to their effects on signaling pathways that play a central role in maintaining neuronal integrity and resistance to stress factors. In particular, the review examines how these compounds regulate key intracellular cascades such as nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1)/antioxidant response element (ARE), Nrf2/PTEN-induced putative kinase 1 (PINK1)/Parkin, nuclear factor-kappa B (NF-\u03baB), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR), which are critically involved in controlling oxidative stress, mitochondrial autophagy, inflammation, and neuronal plasticity. The integrated evaluation of these mechanisms demonstrates that 4H-pyran-based acids can act as multitarget neuroprotective agents capable of influencing both primary metabolic processes and secondary signaling responses to neurotoxic stimuli. Their pleiotropic action highlights the promise of these compounds as molecular scaffolds for the development of novel drugs aimed at preventing or delaying the progression of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases.",
"42531677": "ID: 42531677\nTitle: GATA4 modulates autophagy, apoptosis and tight junction marker remodeling in Bactrian camel Sertoli cells.\nAbstract: Bactrian camels exhibit distinct seasonal estrus, with periodic testicular functional fluctuations regulating their reproductive activity. As a key transcription factor in reproductive modulation, the specific role of GATA4 in the testicular microenvironment of Bactrian camels remains unclear. This study investigates the expression patterns of GATA4 in the testicular tissue during estrus and anestrus phases, alongside its potential regulatory effects on Sertoli cells (SCs) function. Utilizing mRNA sequencing, we analyzed testicular samples in estrus (n\u202f=\u202f3) and anestrus (n\u202f=\u202f3), identifying 291 differentially expressed genes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed that GATA4 was involved in reproduction-related processes, including tight junction formation, autophagy, and cell cycle regulation. Notably, validation showed that GATA4 expression was significantly upregulated in testicular tissue during the anestrus period, with its protein localized primarily in SCs. Gain- and loss-of-function assays revealed that altered GATA4 expression is associated with changes in autophagy-related marker profiles, evidenced by a lower LC3II/LC3I ratio, decreased Beclin-1, and increased P62 expression level. Silencing GATA4 induced opposite alterations in these autophagy-associated molecular markers, and these molecular changes are associated with modified mTOR/NF-\u03baB pathway expression. Additionally, GATA4 influences SCs apoptosis and G0/G1 cell cycle arrest and these cellular phenotypic changes are accompanied by alterations in the PI3K/AKT pathway, which correlates with changed levels of BAX, Caspase-3, BCL2, and CDK1. And moreover, GATA4 modulates the expression of the tight junction markers ZO-1 and Occludin, and these remodeling events are associated with modified WNT1/\u03b2-catenin signaling. In conclusion, GATA4 exhibits dynamic expression patterns throughout the reproductive cycle, which correlates with the modulation of multiple biological processes in SCs, including autophagy-related marker remodeling, apoptosis regulation, and tight junction marker remodeling. This study's findings provide a key molecular target for elucidating the seasonal reproductive mechanism and reproductive regulation of Bactrian camels and enrich the current understanding of reproductive regulatory mechanisms in this species.",
"42533037": "ID: 42533037\nTitle: Hippocampal neuronal progranulin mediates estrogen\u2011deficiency\u2011induced affective vulnerability and lysosomal-autophagic dysfunction.\nAbstract: Perimenopausal women typically face a heightened risk of emotional disturbances, including anxiety and depression. The estrogen decline increases vulnerability to mood disorders, but the molecular mechanisms underlying stress resilience remain unclear. Here, we identify hippocampal neuronal progranulin (PGRN), a secreted neuroprotective glycoprotein, as a key regulator of affective resilience under estrogen-deficient conditions. Ovariectomy (OVX) reduces hippocampal neuronal PGRN expression and induces anxiety- and depression-like behaviors, whereas estradiol supplementation restores both PGRN levels and behavior. Adeno-associated virus (AAV)-mediated overexpression of PGRN alleviates affective deficits across OVX, 4\u2011vinylcyclohexene diepoxide (4-VCD)-induced ovarian failure, and natural aging models, while neuronal, but not microglial, Grn deletion exacerbates stress susceptibility. Mechanistically, PGRN restores lysosomal protease activity, normalizes autophagic flux, activates AMP-activated protein kinase (AMPK) phosphorylation, and rescues mushroom spine loss, thereby restoring cellular and synaptic homeostasis. Intracerebral recombinant PGRN rescues OVX\u2011induced behavioral deficits, and the blood-brain barrier (BBB)-permeable fragment granulin-E (GRN\u2011E) confers similar protection after systemic administration. Collectively, these findings demonstrate that hippocampal neuronal PGRN links estrogen signaling to lysosomal-autophagy pathways and synaptic plasticity, and highlight PGRN or its active fragments as promising therapeutic targets for perimenopausal depression and anxiety.",

Previously reported mouse models exhibited reduced birthrate and survival of affected males, greatly limiting their experimental utility. Here we describe a new mouse model carrying the clinically relevant Sms p.Gly56Ser (SmsG56S) allele in which viable males are recovered at Mendelian ratios, enabling generation of adequately powered cohorts. Hemizygous males produce markedly reduced SMS protein across tissues, recreating the biochemical hallmark of SRS, an elevated spermidine:spermine ratio. SmsG56S/Y males exhibit reduced body size, altered body composition, decreased locomotor and exploratory behaviors, and reduced seizure threshold, aligning with clinical features reported in SRS patients. Serum LDL, HDL, and cholesterol levels were reduced, while brain histology revealed modest region-specific astrocytic changes. Comprehensive polyamine profiling revealed tissue-specific biochemical disturbances, highlighting putrescine elevation in the brain and informing development of translational strategies and windows for intervention. Overall, this improved model reproduces multiple key aspects of the human SRS phenotype and provides a robust platform for mechanistic studies and preclinical evaluation of therapies.",

MicroRNAs (miRNAs), which are critical post-transcriptional regulators, have emerged as important modulators of animal behavior. This study investigated the molecular basis of aggression in pigs ( Sus scrofa), focusing on miRNA-mediated regulation. Hypothalamic miRNA-sequencing of the most aggressive ( n=4) and least aggressive ( n=4) piglets identified nine differentially expressed miRNAs. Among these, miR-27a was significantly upregulated in aggressive individuals. Functional assays demonstrated that both porcine miR-27a and its human ( Homo sapiens) ortholog has-miR-27a-3p, suppressed autophagy, apoptosis, and neuronal plasticity in primary porcine neurons and human SH-SY5Y neuroblastoma cells. To clarify the underlying mechanisms, mRNA-sequencing was performed on porcine neurons transfected with miR-27a mimics or negative controls, identifying 436 differentially expressed genes (84 upregulated and 352 downregulated). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses highlighted eight genes- CBL, PRKCA, SLC38A1, ZBTB16, AANAT, CYP1A1, SLC7A11, and NTRK2-associated with tryptophan metabolism, oxidative stress, and long-term synaptic depression. Bioinformatic analysis and dual-luciferase reporter assays confirmed that miR-27a directly targets the 3'-UTR of PRKCA, thereby suppressing of autophagy, apoptosis, and neuronal plasticity. In vivo, intrahypothalamic injection of mmu-miR-27a-3p in mice ( Mus musculus) reduced motor function and social dominance, and placed the mice at a competitive disadvantage, while supressing neuronal autophagy, apoptosis and plasticity. \u968f\u7740\u96c6\u7ea6\u5316\u52a8\u7269\u751f\u4ea7\u7684\u666e\u53ca\uff0c\u4eba\u4eec\u5bf9\u52a8\u7269\u798f\u5229\u7684\u5173\u6ce8\u65e5\u76ca\u589e\u52a0\u3002\u653b\u51fb\u884c\u4e3a\u4f5c\u4e3a\u5f71\u54cd\u52a8\u7269\u798f\u5229\u7684\u91cd\u8981\u56e0\u7d20\uff0c\u5bf9\u63d0\u5347\u798f\u5229\u6c34\u5e73\u548c\u751f\u4ea7\u6548\u7387\u81f3\u5173\u91cd\u8981\u3002\u800c\u4f5c\u4e3a\u8f6c\u5f55\u540e\u8c03\u63a7\u7684\u5173\u952e\u5206\u5b50miRNA\u5df2\u6210\u4e3a\u52a8\u7269\u884c\u4e3a\u7684\u91cd\u8981\u8c03\u8282\u56e0\u5b50\u3002\u8be5\u7814\u7a76\u65e8\u5728\u4ece\u5206\u5b50\u5c42\u9762\u89e3\u6790\u732a\u653b\u51fb\u884c\u4e3a\u7684\u5f62\u6210\u673a\u5236\uff0c\u91cd\u70b9\u5173\u6ce8 miRNA \u4ecb\u5bfc\u7684\u8c03\u63a7\u4f5c\u7528\u3002\u901a\u8fc7\u5bf9\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\uff08 n = 4\uff09\u548c\u8f83\u5f31\uff08 n = 4\uff09\u4ed4\u732a\u4e0b\u4e18\u8111\u8fdb\u884c miRNA \u6d4b\u5e8f\uff0c\u5171\u9274\u5b9a\u51fa 9 \u79cd\u5dee\u5f02\u8868\u8fbe\u7684 miRNA\u3002\u5176\u4e2d\uff0cmiR-27a \u5728\u653b\u51fb\u884c\u4e3a\u8f83\u5f3a\u7684\u4e2a\u4f53\u4e2d\u663e\u8457\u4e0a\u8c03\u3002\u7ec6\u80de\u529f\u80fd\u5b66\u9a8c\u8bc1\u8868\u660e\uff0cssc-miR-27a \u53ca\u5176hsa-miR-27a-3p \u80fd\u591f\u6291\u5236\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u548c\u4eba\u795e\u7ecf\u6bcd\u7ec6\u80de\u7624\u7ec6\u80de\u7cfb\uff08SH-SY5Y\uff09 \u7684\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002\u4e3a\u4e86\u8fdb\u4e00\u6b65\u63a2\u7a76 miR-27a \u5bf9\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u7684\u8c03\u63a7\u4f5c\u7528\uff0c\u901a\u8fc7\u5bf9\u8f6c\u67d3 miR-27a \u6a21\u62df\u7269\u548c\u9634\u6027\u5bf9\u7167\u7684\u732a\u539f\u4ee3\u795e\u7ecf\u7ec6\u80de\u8fdb\u884c mRNA-seq\uff0c\u5171\u9274\u5b9a\u51fa 436 \u4e2a\u5dee\u5f02\u8868\u8fbe\u57fa\u56e0\uff0884 \u4e2a\u4e0a\u8c03\uff0c352 \u4e2a\u4e0b\u8c03\uff09\u3002\u5bcc\u96c6\u5206\u6790\uff08GO\u3001KEGG\u3001PPI\uff09\u53d1\u73b0\u67098\u4e2a\u57fa\u56e0\u2014\u2014 CBL\u3001 PRKCA\u3001 SLC38A1\u3001 ZBTB16\u3001 AANAT\u3001 CYP1A1\u3001 SLC7A11 \u548c NTRK2\uff0c\u4e0e\u8272\u6c28\u9178\u4ee3\u8c22\u3001\u6c27\u5316\u5e94\u6fc0\u548c\u957f\u671f\u7a81\u89e6\u6291\u5236\u7b49\u901a\u8def\u76f8\u5173\u3002\u751f\u7269\u4fe1\u606f\u5b66\u548c\u53cc\u8367\u5149\u7d20\u9176\u62a5\u544a\u57fa\u56e0\u68c0\u6d4b\u8868\u660e\uff0cmiR-27a \u76f4\u63a5\u9776\u5411 PRKCA \u7684 3'-UTR\uff0c\u4ecb\u5bfc\u81ea\u566c\u3001\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u7684\u6291\u5236\u3002\u6d3b\u4f53\u5b9e\u9a8c\u8868\u660e\uff0c\u5c0f\u9f20\u4e0b\u4e18\u8111\u5185\u6ce8\u5c04 mmu-miR-27a-3p \u4f1a\u964d\u4f4e\u5176\u8fd0\u52a8\u529f\u80fd\uff0c\u524a\u5f31\u5176\u793e\u4f1a\u652f\u914d\u5730\u4f4d\uff0c\u5e76\u4f7f\u5176\u5904\u4e8e\u7ade\u4e89\u52a3\u52bf\uff0c\u540c\u65f6\u6291\u5236\u5c0f\u9f20\u795e\u7ecf\u5143\u7684\u81ea\u566c\u3001\u7ec6\u80de\u51cb\u4ea1\u548c\u53ef\u5851\u6027\u3002.",

Mitophagy, the selective degradation of damaged or superfluous mitochondria, plays a central role in maintaining mitochondrial integrity and metabolic balance. This review provides a comprehensive overview of the best-characterized PINK1-PRKN/parkin-dependent mitophagy pathway and the expanding repertoire of PRKN-independent mechanisms, including additional ubiquitin-dependent, receptor-mediated, and lipid-mediated pathways. We explore how these pathways intersect and compensate for one another, highlighting the complexity and adaptability of mitochondrial quality control networks. Furthermore, we discuss how dysregulated mitophagy contributes to the onset and progression of neurodegenerative diseases. By examining the interplay between mitophagy pathways and their regulation under physiological and pathological conditions, this review underscores the therapeutic potential of targeting mitophagy in neurodegeneration.

Chronic neuroinflammation drives progressive retinal ganglion cell (RGC) loss independent of intraocular pressure, yet safe, sustained and precise neuroprotective modulation of the retinal inflammatory microenvironment remains a significant challenge. We developed an injectable fibrin gel delivery system loaded with ginseng-derived exosomes (GE-fibrin gel, GE-gel) to modulate microglial polarization, reduce retinal inflammation and promote RGC survival. In vitro, GE showed strong antioxidant and anti-apoptotic effects by getting rid of reactive oxygen species caused by oxidative stress and lowering apoptosis in R28 cells. Both GE and GE-gel stopped lipopolysaccharide from causing pro-inflammatory M1 polarization of microglia and increased anti-inflammatory M2 phenotypic change. Intravitreal injection of GE-gel suppressed pro-inflammatory microglial activation, diminished neuroinflammation and improved the survival of RGCs in a chronic ocular hypertension rat model. These results show that GE-gel could promote microglial polarization, change the immune environment in the retina and protect RGCs functionally over the long term.

However, liver sinusoidal endothelium-mediated nanoparticle elimination remains far less understood than liver macrophage uptake despite both processes being involved in hepatic detoxification. Using water-soluble Au25(o-MBA)18 (o-MBA: o-mercaptobenzoic acids) with optimized local hydrophobicity for weak protein-binding affinity and high endothelium targeting as probes, we report an exosome-mediated systemic clearance for endocytosed nanoclusters in sinusoidal endothelial cells. Au25(o-MBA)18 can effectively avoid phagocytosis by liver macrophage, are initially endocytosed by sinusoidal endothelial cells through clathrin-dependent endocytosis, processed through endosomal pathways, and released as exosomes containing nanoclusters into the bloodstream. During the exosome biogenesis, Au25(o-MBA)18 progressively transform into flower-like aggregates (approximately 100 nm). These circulating exosomes traverse the glomerular membrane through autophagy in glomerular endothelial cells and podocytes before urinary excretion. Here, this exosome-mediated pathway converts exogenous ultrasmall gold nanoparticles into biocompatible endogenous exosome-enveloped cargos for systemic circulation with reduced toxicity, providing a foundation for developing next generation of safe and effective nanomedicines.",

In this study, circular RNA circAP2B1 is identified as a critical regulatory molecule that is markedly upregulated in ESCC tissues and patient serum and strongly associated with poor prognosis. Mechanistically, tumor-derived exosomes efficiently deliver circAP2B1 to tumor-associated macrophages (TAMs), where it serves as a distinct molecular scaffold that simultaneously binds the transcription factor ESRRA and the nuclear import receptor KPNA1, facilitating ternary complex formation and ESRRA nuclear translocation. Once in the nucleus, ESRRA directly activates the transcription of Mitofusin 2 (MFN2), a pivotal regulator of mitochondrial fusion, thereby enhancing mitochondrial oxidative phosphorylation, improving ATP production efficiency, and establishing a metabolically optimized intracellular environment that ultimately drives TAMs toward a pro-tumor M2 phenotype. Both in vitro and in vivo experiments demonstrate that targeted intervention of the circAP2B1/ESRRA/KPNA1/MFN2 signaling axis effectively reverses M2 polarization and markedly suppresses tumor progression. This study uncovers a novel exosomal circRNA-mediated metabolic-immune regulatory pathway and offers new avenues for the diagnosis and treatment of ESCC. The findings not only expand the understanding of circRNA functions in tumor immunity but also provide a theoretical basis for the development of therapies targeting the metabolic-immune axis.",

Conversely, phase-separated condensates have also been associated with aberrant protein misfolding and subsequent aggregation in neurodegenerative disease-related processes. Protein phase separation and phase transitions involve the formation of heterogeneous and dynamic assemblies that can evolve into gel-like or semi-crystalline states, which are challenging to characterize using high-resolution structural biology techniques.

Research indicates that IF enhances insulin sensitivity, facilitates weight reduction and stimulates cellular repair pathways, including autophagy. Physiological adaptations to fasting are reflected in favorable alterations in biomarkers and metabolic processes. This review examines the current evidence on IF by analyzing studies retrieved through schematic searches of the MEDLINE via PubMed database, Embase and ScienceDirect using specific keyword combinations. It focuses on commonly practiced regimens- Time-restricted eating (TRE) (16/8 method), Alternate-day fasting (ADF), the 5:2 intermittent energy-restriction diet and One meal a day (OMAD) approaches and explores their effects on cardiovascular function, metabolic regulation, cognitive performance and longevity. Various IF regimens including the TRE (16/8 method), ADF, the 5:2 diet and OMAD approaches are discussed in relation to their effects on cardiovascular health, cognitive function, metabolic regulation, aging and longevity. While most finding highlight significant health benefits, inconsistencies and methodological limitations are also reported. Mechanistically, IF orchestrates a coordinated metabolic response through modulation of key nutrient sensing pathway such as AMP activated protein kinase (AMPK), mechanistic target of rapamycin (mTOR) and unc-51-like kinase 1 (ULK1). These cascades interact with Sirtuins (SIRT1/3), peroxisome proliferator activated receptor gamma coactivator-1\u03b1 (PGC-1\u03b1) and the transcription factor EB (TFEB) to regulate autophagy, mitochondrial biogenesis, oxidative stress defense and cellular repair.

"42538520": "ID: 42538520\nTitle: The Pleiotropic Therapeutic Perspectives of GLP-1 and GIP Receptor Agonists in Spinal Cord Injury: A Narrative Review.\nAbstract: Spinal cord injury (SCI) constitutes a major global health challenge. The pathophysiology of SCI involves many aspects. Current treatments, such as early decompression and glucocorticoids, target single pathways and show limited efficacy with safety concerns. In this context, interventions based on the incretin system are now considered attractive candidates for SCI intervention. This review comprehensively outlines the mechanisms underlying microenvironmental imbalance following SCI and explores glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists as promising options. These agents, recognized for their role in managing diabetes and body weight, demonstrate substantial pleiotropic effects beyond simple glycemic regulation. These beneficial actions include neuroprotection, anti-inflammatory effects, and the promotion of tissue repair. Preclinical SCI studies have indicated that GLP-1 receptor agonists and GIP receptor agonists reduce inflammation by shifting microglia/macrophages to anti-inflammatory phenotypes, suppress apoptosis, increase autophagy, alleviate oxidative stress, promote axonal regeneration, improve the injury microenvironment, and have the potential to regulate immune cells. Related research in other neurological disorders supports these mechanisms, with dual agonists showing superior efficacy.

Autophagy is essential for endothelial homeostasis, yet its role in aldosterone-mediated vascular dysfunction remains unclear. We tested whether aldosterone impairs autophagic flux and whether restoring autophagy via Beclin1 (BCN1) activation protects vascular and cardiac function. Endothelial and vascular responses to aldosterone were assessed in wild-type mice, BCN1 gain-of-function mice (Becn1), and mice treated with spermidine or a BCN1-activating TB-peptide. Vascular function, nitric oxide (NO)/reactive oxygen species (ROS) production, autophagy markers, endothelial migration, and cardiac fibrosis were evaluated using wire myography, fluorescence assays, Western blotting, confocal microscopy, migration assays, and histology. Aldosterone impaired endothelium-dependent relaxation, decreased NO, increased ROS, and disrupted autophagic flux in an MR-dependent manner, indicated by LC3 accumulation and reduced p62 and BCN1 expression. Spermidine restored endothelial function and normalized NO and ROS levels. BCN1 gain-of-function mice were protected from aldosterone-induced endothelial dysfunction and exhibited reduced coronary and myocardial fibrosis. TB-peptide activation of BCN1 enhanced autophagic flux, improved vascular function, decreased cardiac fibrosis, and rescued endothelial migration impaired by aldosterone. Aldosterone induces endothelial dysfunction by suppressing autophagic flux through MR activation. Genetic or pharmacologic enhancement of BCN1-dependent autophagy restores endothelial homeostasis and prevents vascular and cardiac injury, identifying autophagy activation as a promising therapeutic approach for cardiovascular diseases associated with mineralocorticoid excess.",

Here, we show that PGRN deficiency contributes to cerebral microvascular perfusion and induces alterations within the neurovascular unit. In vivo two-photon imaging revealed increased capillary stalling and reductions in cerebral blood flow (CBF), driven in part by increased leucocyte-capillary interactions and elevated endothelial ICAM-1 expression. Transcriptomic profiling of isolated cerebral microvessels demonstrated coordinated upregulation of immune and extracellular matrix pathways alongside suppression of angiogenic and stress-response programs, indicative of endothelial activation. Cross-species analyses identified partial conservation of these vascular signatures in endothelial cells from human FTD-GRN patients, associated with dysregulated angiogenic and inflammatory signaling. Despite altered tight junction organization and reduced solute carrier transporter expression, blood-brain barrier (BBB) permeability remained largely intact, suggesting functional rather than structural BBB disruption, as well as. These vascular changes were accompanied by broad alterations in the morphology of astrocytes, pericytes, and microglial cells. Here we determined a novel role for progranulin in cerebrovascular homeostasis and established microvascular dysfunction as a key driver of FTD-GRN pathophysiology.",

KIF1A mutations variably disrupt synaptic vesicle trafficking, but the effects of KIF1A mutations on other trafficking pathways remain unexplored. Autophagy is a conserved pathway required for neuronal homeostasis. We investigated the role of KIF1A in autophagy using gene-edited human IPSC-derived neurons. KIF1A loss inhibited the trafficking of ATG9, a transmembrane lipid scramblase necessary for autophagosome biogenesis. This deficit significantly reduced autophagosome biogenesis and the density of axonal autophagosomes. KIF1A loss also depleted lysosomes from the axon, inhibiting autophagosome maturation. In neurons gene-edited to heterozygously express a pathogenic variant linked to a Rett-like syndrome in KAND patients, we also noted significant deficits in autophagy and lysosomal trafficking. Together, these results suggest that KIF1A-mediated transport is critical to neuronal autophagy and that deficits in autophagy may contribute to pathogenesis in KAND.",
"42539297": "ID: 42539297\nTitle: Targeted modulation of IGFBP5/IGF1, THPO, and P38 MAPK signaling are potent therapeutic strategies generalizable for mitochondrial respiratory chain disease and osteosarcoma.\nAbstract: Primary mitochondrial diseases (PMD) have limited disease-modifying therapies, currently applicable to only 3 of over 400 discrete gene disorders. Cycloheximide (CHX) is a global cytosolic translation inhibitor we previously reported to rescue PMD preclinical models, although its toxicity precluded clinical development. To identify specific mediators underlying CHX treatment benefit in PMD, SOMAscan-based proteomics was performed in complex I deficient and genetic disease fibroblast cell line models grown in galactose. Thrombopoietin (THPO) and insulin-like growth factor binding protein 5 (IGFBP5) were the only two differentially regulated proteins, together with ERK/MAPK pathway dysregulation, identified upon CHX treatment in PMD versus healthy control cells. THPO inhibition by siRNA or pharmacologic approaches rescued stress-induced viability loss in patient fibroblasts having diverse PMD gene etiologies, and significantly improved mitochondrial stress, linear growth, and neuromuscular function in a classical ndufs2 -/- C. elegans model. IGFBP5 overexpression by lentiviral or mRNA approaches rescued cell viability across distinct PMD gene etiologies, as did IGF1 pharmacologic inhibition across both PMD mutant and C. elegans models. MAPK pharmacologic inhibition rescued multiple distinct complex I disease cells' survival, as well as mitochondrial stress in SLC25A46 -/- C. elegans . Combination therapies targeting multiple of these glucose signaling pathway proteins, together with glucose and N-acetylcysteine, yielded superior therapeutic benefit in complex I disease cell and C. elegans models. Additionally, single or combined pharmacologic inhibition of THPO or IGF1 significantly enhanced primary and metastatic osteosarcoma cell death. Collectively, targeted small molecule and genetic modulation of THPO, IGF1, or MAPK recapitulated the significant therapeutic benefit of CHX in PMD, while avoiding global translation inhibition. These novel PMD therapies likely confer benefit by attenuating MAPK-driven autophagy and potentially promoting noncanonical glucose uptake, improving cellular energy balance. Overall, these glucose signaling cellular pathway targets hold broad therapeutic promise for PMD patients, warranting further clinical research development.",
"42539973": "ID: 42539973\nTitle: CNOT11 depletion is associated with autophagy-related responses and IL-6-JAK-STAT signaling in cancer cells.\nAbstract: The CCR4-NOT complex is a central regulator of deadenylation-mediated mRNA decay, yet the role of its vertebrate-specific subunit CNOT11 remains unclear. We investigated the role of CNOT11 in cellular stress responses using siRNA-mediated knockdown, immunoblotting, immunoprecipitation, transcriptomic analysis, quantitative RT-PCR, ELISA, cycloheximide chase assays, actinomycin D treatment, and poly(A) tail analysis. CNOT11 depletion did not markedly alter the expression of other CCR4-NOT subunits but reduced the association of CNOT10 with the complex. CNOT11 knockdown was associated with LC3-II accumulation, transcriptional upregulation of autophagy-related genes, and changes in AMPK/ULK1 signaling. Increased IL-6 expression and secretion and enhanced STAT1 and STAT3 phosphorylation were also observed. IL-6 knockdown or STAT3 inhibition partially attenuated LC3-II accumulation. Increased IL-6 expression was associated with elevated transcription, without detectable changes in mRNA stability or poly(A) tail length. These findings suggest that CNOT11 depletion is associated with LC3-II accumulation and other autophagy-related responses, with IL-6-JAK-STAT signaling contributing partially to this phenotype. Definitive assessment of autophagic flux and the causal positioning of IL-6 signaling will require further studies using gold-standard flux assays and IL-6 rescue or neutralization approaches.",

The polyamine spermidine was suggested to exert neuroprotective effects, but its concentration-dependent impact on longevity, neuronal integrity, and behavior remains still not well studied. Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC). Our results suggest that spermidine at low doses has the potential to be a general-purpose neuroprotector.",

Aging contributes not only to the increased incidence of these disorders but also to their progression through interconnected mechanisms, including endothelial dysfunction, oxidative stress, chronic inflammation, mitochondrial dysfunction, cellular senescence, metabolic imbalance, and gut microbiota dysbiosis. These processes collectively impair neuronal survival, synaptic plasticity, and cognitive and motor functions. Traditional Chinese medicine (TCM), with its characteristic multi-component and multi-target therapeutic strategies, has emerged as a promising approach to counteract age-associated neurological decline. Accumulating preclinical studies suggest that TCM interventions may exert neuroprotective, anti-inflammatory, and antioxidant effects, modulate autophagy, restore metabolic homeostasis, and potentially delay cellular senescence. However,\u00a0high-quality clinical evidence on safety and efficacy remains limited. This review summarizes current insights into the molecular interplay between aging and neurological disorders and highlights the therapeutic potential of TCM in targeting hallmarks of aging, providing perspectives for integrative prevention and treatment strategies for neurodegenerative and neurovascular diseases.",

Glial cells, comprising microglia, astrocytes, oligodendrocytes, and ependymal cells, serve as key immune regulators in the central nervous system, where they are essential for maintaining ALP homeostasis, promoting proteostasis, and modulating neuroinflammatory responses. Here, we systematically review the regulatory roles of glial ALP in AD pathology, emphasizing its involvement in amyloid accumulation, tau hyperphosphorylation, synaptic impairment, white matter damage, and mitochondrial as well as other organelle dysfunction, and provide an in-depth analysis of key signaling pathways including TFEB, mTOR, and NLRP3. Furthermore, we outline therapeutic strategies aimed at restoring lysosomal function, regulating autophagic flux, and suppressing inflammation, along with a discussion of the multi-target regulatory potential of acupuncture and natural bioactive agents. We also highlight emerging ALP-associated biomarkers and their potential utility in early diagnosis and treatment response assessment. The objective of this review is to uncover the mechanistic interplay between glial ALP dysregulation and the pathological cascade of AD, offering a conceptual framework for the development of novel therapeutics that integrate neuroprotection with immune modulation.",

Previous pharmacological investigations have shown that phytochemicals derived from these herbs exhibit neuroprotective properties against cerebral ischemia-reperfusion (CI/R) injury. Nevertheless, the underlying principles governing the combined application of Huangqi and Danshen (QD) and the molecular pathways involved in their therapeutic efficacy remain unexplored in ischemic stroke management. This study sought to systematically investigate the bioactive components in the QD formulation and elucidate their mechanisms of action against cerebral ischemic injury. The therapeutic effects of QD were evaluated in a mouse model of middle cerebral artery occlusion (MCAO). UHPLCHRMS was used to identify QD-derived components in blood and brain tissues. An SSA-BP neural network was constructed to predict the optimal combination of active ingredients. 4D label-free proteomics, coupled with GO and KEGG enrichment analyses, was performed to identify key pathways. Molecular docking and molecular dynamics simulations were used to validate candidate targets. Mitochondrial function and iron homeostasis were assessed by measuring ROS, mitochondrial membrane potential (\u0394\u03a8m), ATP, complex I activity, Fe2+, and the GSH/GSSG ratio. Western blotting and immunofluorescence were used to detect FUNDC1, Nrf2, SLC7A11, NCOA4, p62, FTH1, UQCRC2, and GPX4. The autophagy inhibitor 3-MA was used for mechanistic validation. For cellular studies, HT22 cells were subjected to oxygen-glucose deprivation/reoxygenation (OGD/R), and QD was added during reoxygenation. Cell viability and cytotoxicity were assessed using CCK-8 and LDH assays, respectively. ROS, \u0394\u03a8m, Fe2+, and GSH were measured using commercial kits. Western blotting was used to analyze FUNDC1, UQCRC2, LC3-II/I, p62, GPX4, SLC7A11, NCOA4, Nrf2, and FTH1. siFUNDC1 was transfected 48 h before OGD/R to assess FUNDC1 dependency. Among the tested ratios (1:1, 2:1, 3:1, 3:2, and 2:3), the 3:2 QD combination was the most effective, significantly improving neurological function, reducing infarct size, and alleviating neuronal damage in MCAO mice. UHPLCHRMS identified 21 compounds absorbed into the bloodstream, seven of which were detected in brain tissue. Astragaloside IV, astragaloside II, lithospermic acid, tanshinone IIA, and calycosin were identified as key active components. Their combination, predicted by the SSA-BP neural network, exerted significant neuroprotection in vivo. Proteomics revealed 124 differentially expressed proteins, with GO and KEGG enrichment analyses identifying mitophagy and ferroptosis as the primary therapeutic pathways. Molecular docking and dynamics analyses revealed high-affinity binding interactions between QD constituents and key targets, including FUNDC1, UQCRC2, GPX4, and SLC7A11. QD upregulated FUNDC1, UQCRC2, GPX4, SLC7A11, Nrf2, and FTH1 and downregulated p62 and NCOA4; these effects were partially reversed by 3-MA. In HT22 cells, QD improved cell viability, reduced LDH release, restored \u0394\u03a8m and GSH levels, and attenuated ROS and Fe\u00b2\u207a accumulation following OGD/R. The protein expression changes were consistent with those observed in vivo. Knockdown of FUNDC1 largely blocked the protective effects of QD, confirming that FUNDC1 is essential for QD-mediated neuroprotection. QD ameliorates MCAO-induced cerebral ischemic injury via mitophagy and ferroptosis pathways, offering a novel therapeutic perspective for treating ischemic stroke with traditional Chinese medicine that tonifies Qi and promotes blood circulation.",

However, clinical evidence for combined microneedling-assisted topical protocols in this setting remains limited.ObjectivesThis preliminary pilot observational study explored the short-term feasibility, patient-reported outcomes, tolerability, and qualitative photographic findings associated with a combined microneedling-assisted Panax ginseng exosome protocol with adjunctive inner gel use.DesignSingle-arm preliminary pilot observational study.MethodsFourteen women (mean age, 48.6 years; range, 24-63 years) underwent three treatment sessions at 2-week intervals, followed by a final assessment 2 weeks after the third treatment session, resulting in a total study duration of 6 weeks from baseline to final follow-up for each participant. Microneedling was performed on the vulvar area using a 2-mm dermaroller, followed by topical application of a Panax ginseng exosome formulation. Participants also used an adjunctive inner gel between visits. Outcomes included the Vulvovaginal Symptom Questionnaire (VSQ), the Day-to-Day Impact of Vaginal Aging (DIVA) questionnaire, procedural pain assessed using a visual analogue scale (VAS), safety observations, and qualitative clinical photographic assessment.ResultsTotal VSQ score decreased after treatment (mean change, -2.86; 95% confidence interval [CI], -4.76 to -0.95; p = 0.00648). Total DIVA score also decreased (mean change, -5.43; 95% CI, -9.55 to -1.30; p = 0.0138), with significant improvement in the daily activities domain (median change, -2.0; p = 0.00849). The emotion and sexual life domains showed directional decreases but did not reach statistical significance. Procedure-related pain was transient and generally decreased within 30 minutes after treatment. Clinical photographs showed qualitative observational changes in pigmentation intensity and skin tone uniformity. No serious adverse events were observed during the short follow-up period.ConclusionThis small uncontrolled pilot study found that the combined microneedling-assisted Panax ginseng exosome protocol with adjunctive inner gel use was associated with short-term improvements in patient-reported vulvovaginal symptoms and qualitative vulvar skin tone observations. Because of the single-arm design, small sample size, combined intervention, subjective photographic assessment, and short follow-up, these findings should be interpreted as preliminary and hypothesis-generating. Many women experience vulvovaginal symptoms such as dryness, itching, irritation, discomfort, or pain during sexual activity. Some women also have concerns about changes in vulvar skin tone. This small pilot study looked at a combined nonhormonal treatment using microneedling, a topical Panax ginseng exosome product, and home use of an inner gel. Fourteen women took part. Each participant received three treatment sessions, 2 weeks apart, and had a final assessment 2 weeks after the third session. The total study duration was 6 weeks. After treatment, participants reported lower vulvovaginal symptom scores and lower daily impact scores. The daily activities score improved, while emotional well-being and sexual life scores showed decreasing trends but did not significantly improve. Treatment-related pain was temporary and generally decreased within 30 minutes. No serious adverse events were observed during the short follow-up period. Clinical photographs showed visual changes in skin tone in some cases, but these photographs were not measured using objective color tests or blinded grading. Because this study included only 14 participants, had no control group, used a combined treatment, and had short follow-up, the findings should be considered preliminary. Larger controlled studies are needed to confirm safety, durability, and clinical usefulness.",

In recent years, circular RNAs (circRNAs), a class of covalently closed non-coding RNAs, have emerged as critical regulators of gene expression in OA pathogenesis. Due to their high stability, tissue specificity, and evolutionary conservation, circRNAs have attracted increasing attention as key molecular modulators of cartilage homeostasis and potential therapeutic targets. This review comprehensively summarizes current advances in the molecular mechanisms of circRNAs in OA, with a particular focus on their roles as competing endogenous RNAs (ceRNAs), epigenetic regulators, and mediators of intercellular communication via exosomes. Current evidence indicates that circRNAs participate in multiple pathological processes associated with OA, including extracellular matrix (ECM) degradation, chondrocyte apoptosis, autophagy dysfunction, inflammatory signaling, and mitochondrial stress, primarily through modulation of signaling pathways such as NF-\u03baB, PI3K/AKT, PTEN, and SIRT. Emerging evidence further highlights their involvement in epigenetic regulation via DNA methylation machinery and their participation in exosome-mediated intercellular communication within the joint microenvironment. Importantly, circRNAs exhibit dual functional roles, acting either as pathogenic amplifiers of cartilage degeneration or as protective regulators that promote chondrocyte survival and tissue repair. This functional versatility underscores their potential as both diagnostic biomarkers and therapeutic targets in OA. Moreover, advances in extracellular vesicle-based delivery systems and synthetic RNA engineering provide promising strategies for translating circRNA biology into clinical applications. Despite these advances, challenges remain regarding mechanistic complexity, tissue-specific functions, and efficient in vivo delivery systems. A deeper understanding of circRNA regulatory networks may facilitate the development of next-generation RNA-based precision therapies for osteoarthritis.",

While levodopa remains the gold standard for managing PD motor symptoms, it lacks disease-modifying efficacy, necessitating new neuroprotective therapies. Mitochondrial dysfunction and impaired autophagy are key hallmarks of PD. This study utilized 1-methyl-4-phenylpyridinium (MPP+)-treated SH-SY5Y cells to investigate the neuroprotective mechanisms of catalpol, an iridoid glycoside derived from Rehmannia glutinosa. We found that catalpol attenuated MPP+-induced neurotoxicity, mitochondrial membrane depolarization, and ATP depletion. This protection was critically dependent on autophagy; it was enhanced by the activator rapamycin but abolished by the inhibitor wortmannin and the autophagosome-lysosome fusion inhibitor bafilomycin A1. Catalpol activated autophagy by increasing autophagosome formation, elevating Beclin 1 and LC3-II levels, and promoting p62 degradation. Furthermore, catalpol reversed MPP+-induced mitophagy suppression and restored the regulatory protein PINK1 and DJ-1 expression. Given that Akt/BDNF/Bcl-2 and TrkB/BDNF pathways promote neuronal survival, we investigated their involvement. We found that the TrkB agonist 7,8-DHF mimicked catalpol's neuroprotection against MPP+-induced neurotoxicity, whereas the pan-Trk inhibitor GNF-5837 abolished it. Western blotting demonstrated that catalpol reversed MPP+-mediated suppression of TrkB and Akt phosphorylation, as well as BDNF and Bcl-2 expression. Molecular docking indicated that catalpol may interact with the TrkB ligand-binding domain as 7,8-DHF and shares key binding residues. Our findings suggest that catalpol exerts neuroprotection via a dual mechanism: preserving mitochondrial function through PINK1/DJ-1-mediated mitophagy and activating the TrkB/Akt/BDNF/Bcl-2 survival pathway, potentially by interacting with the TrkB receptor, highlighting its therapeutic potential for PD.",
"42546981": "ID: 42546981\nTitle: New insights on microglial lysosomal acidification: A therapeutic target of neurodegenerative diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), maintain brain homeostasis and respond to pathological insults. Microglial dysfunction has been implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Impaired lysosomal function, particularly defective lysosomal acidification, leads to the accumulation of undegraded material, thereby promoting neuroinflammation and neuronal damage. This review examines the mechanisms governing lysosomal acidification in microglia and evaluates its potential as both a therapeutic target and a prognostic biomarker in neurodegenerative diseases. The literature on microglial lysosomal acidification, lysosomal pH regulation, autophagy, and neurodegeneration was searched in PubMed, Scopus, and Web of Science. Relevant mechanistic, preclinical, and translational studies were critically appraised and synthesized. Lysosomal acidification is increasingly recognized as a key regulator of microglial function and homeostasis. Defective acidification, driven by dysregulation of the vacuolar H+-ATPase (V-ATPase) proton pump, TFEB/TFE3 signaling pathways, and lysosomal ion channels such as TRPML1 and TMEM175, impairs autophagic flux and substrate degradation, facilitating the accumulation of neurotoxic aggregates including amyloid-\u03b2 and \u03b1-synuclein. Emerging evidence suggests that the degree of microglial lysosomal acidification may serve as a prognostic biomarker for disease progression and therapeutic response. Restoration or enhancement of lysosomal acidification through pharmacological modulation of lysosomal pH, activation of autophagy, or targeting of key regulatory pathways has been shown to re-establish microglial homeostasis, attenuate neuroinflammation, and confer neuroprotection in preclinical models. Restoration of microglial lysosomal acidification represents a promising therapeutic strategy for neurodegenerative diseases. A deeper understanding of the molecular mechanisms regulating lysosomal acidification in microglia may facilitate the identification of novel biomarkers and therapeutic targets, ultimately contributing to the development of innovative interventions for neurodegenerative disorders.",
"42548587": "ID: 42548587\nTitle: Autophagy in ischemic stroke: pathophysiology, therapeutics, and challenges ahead.\nAbstract: Autophagy is a fundamental cellular homeostatic process that exerts a dual, context-dependent influence on the pathophysiology of ischemic stroke. Functioning as both a neuroprotective survival mechanism and a neurotoxic pathway, autophagy presents a complex therapeutic challenge as well as a potential target for molecular intervention. This narrative review synthesizes preclinical and emerging clinical evidence to summarize key mechanisms regulating autophagy in ischemic injury, evaluate therapeutic strategies, and identify promising molecular pathways and druggable targets for translational development. In the early ischemic phase, moderate autophagic activation facilitates neuronal survival by clearing damaged mitochondria and protein aggregates, thereby reducing oxidative stress and modulating neuroinflammation. This protective response is primarily mediated by regulators such as Beclin-1, the conversion of LC3-I to LC3-II, and the energy-sensing AMP-activated protein kinase pathway. Conversely, sustained or excessive autophagy, particularly during late-stage reperfusion, exacerbates neuronal injury through impaired lysosomal fusion, autophagosome accumulation, and the triggering of autophagic cell death and ferroptosis. Preclinical evidence highlights a critical Goldilocks zone of activation, suggesting that therapeutic success hinges on maintaining autophagic flux within narrow physiological limits. Advancing these therapies into clinical practice requires precise spatiotemporal modulation, potentially as an adjunct to mechanical thrombectomy, as well as the development of robust, real-time biomarkers. A comprehensive understanding of the molecular and genetic determinants of autophagy, including sex-specific responses, is essential to bridge the translational gap and establish autophagy as a viable target for precision stroke medicine.",

Dapagliflozin, a sodium-glucose cotransporter 2 inhibitor widely used in type 2 diabetes and cardiorenal disease, has attracted attention as a candidate modulator of cognitive decline because its established peripheral pharmacology extends beyond glucose lowering to include natriuresis, blood pressure reduction, weight loss, improved insulin resistance, reduced oxidative and inflammatory stress, and favorable cardiorenal effects. In this review, we examine the pharmacological basis by which these systemic actions could influence the neurovascular unit, mitochondrial homeostasis, glial activation, autophagy-related signaling, and synaptic plasticity pathways implicated in cognitive impairment. We summarize preclinical evidence suggesting that dapagliflozin can improve cognitive performance and modulate pathways such as AMPK-mTOR, Wnt/\u03b2-catenin, CREB/BDNF, oxidative stress responses, and neuroinflammatory signaling in experimental models, while also critically evaluating the limitations of these models. We then assess the current human evidence, distinguishing observational studies that suggest lower dementia risk from randomized clinical evidence that has not yet established a definitive cognition-related benefit. We argue that dapagliflozin should currently be viewed not as a proven cognitive therapeutic, but as a mechanistically plausible metabolic-neurovascular intervention whose relevance may be greatest in metabolically vulnerable phenotypes. Finally, we outline key translational challenges, including uncertainty regarding direct central target engagement, the need for biomarker-enriched trial designs, and the importance of integrating pharmacological, vascular, and neurodegenerative frameworks in future studies.",

MBRs contain ribosomes, mitochondria, translation factors, and selected mRNAs and small RNAs concentrated within a condensate\u2011like ribonucleoprotein core and can support protein synthesis after extracellular release. These features distinguish MBRs from more extensively studied exosomes and microvesicles yet also place them within a broader continuum of large EVs with organelle\u2011rich, cell\u2011like properties. This review summarizes current knowledge of MBR biogenesis, molecular organization, and translation competency; contrasts MBRs with canonical EVs and other large EVs; and discusses possible roles in development, tissue homeostasis, disease, and brain function. Particular emphasis is placed on outstanding mechanistic and physiological questions, including how MBR translation is regulated, which recipient cells interact with endogenous MBRs, and whether translation\u2011competent EVs offer practical advantages over existing EV platforms for therapeutic or biotechnological applications.",

Both conditions share significant disruptions in metabolic and inflammatory signalling despite having different genetic origins and clinical manifestations; underscoring the necessity of pathway-oriented treatment approaches. In the central nervous system, peroxisome proliferator-activated receptor-\u03b3 (PPAR-\u03b3), a ligand-activated nuclear receptor has become an important regulator of inflammation, redox homeostasis, mitochondrial biogenesis and cellular stress responses.

The therapeutic potential of PAC is hindered due to its poor water solubility and low brain bioavailability. In the current study, a PAC-loaded nanoemulsion (PAC-NE) was formulated to deliver the drug through the intranasal (IN) route for better solubilization, nasal absorption, and brain targeting. The optimized formulation of PAC-NE exhibited a mean droplet size of 18.78\u202f\u00b1\u202f0.4\u202fnm and a polydispersity index (PDI) value of 0.183\u202f\u00b1\u202f0.007, representing a highly homogenous and uniform NE, which is appropriate for nasal administration. In vitro evaluation of the anticancer efficacy in 2D cell culture and 3D tumor spheroid model (3DS) proved that PAC-NE greatly improved the cellular uptake, cytotoxicity, and tumor spheroid inhibition activity compared with free PAC. In addition, ex vivo nasal permeation was greatly improved by the optimized formulation, showing a flux value of 1.27\u202f\u00b1\u202f0.06\u202f\u00b5g/cm2/h and a permeability coefficient value of 2.4\u202f\u00d7\u202f10\u207b7\u202f\u00b1\u202f0.19\u202fcm/s, which were significantly higher than that of the plain drug. Moreover, the histopathological examination demonstrated no sign of damage to the nasal mucosa. Pharmacokinetics analysis following IN application revealed that the optimized NE depicted greater brain-targeting ability, where there was an improvement in %DTE by 1.99-fold and in %DTP by 2.75-fold in comparison to free PAC. Overall, from the above observations, it can be concluded that PAC-NE is a non-invasive delivery system which shows promising results for better brain delivery thereby supporting the clinical translation of PAC for GBM therapy.",

While BMSC-derived small extracellular vesicles (BMSC-Exo) are neuroprotective, their ability to repair mitochondrial deficits is limited. We engineered mitochondrial-enriched sEVs (Exo-Mito) to evaluate their effects on microglia-neuron interactions in a PD-relevant model. BMSC-Exo-Mito were characterized via TEM, NTA, and immunoblotting. Their therapeutic efficacy was assessed using an MPP\u00a0+\u00a0-induced BV2/SH-SY5Y transwell co-culture model. Assessments included ROS levels, mitochondrial membrane potential, ATP quantification, mitophagy flux, and signaling pathway analysis. Exo-Mito significantly restored mitochondrial homeostasis by reducing ROS, preserving membrane potential, and increasing ATP production. Mechanistically, Exo-Mito enhanced PINK1/Parkin-dependent mitophagy and PGC-1alpha/TFAM-mediated biogenesis. In BV2 microglia, Exo-Mito suppressed the NF-kappaB/NLRP3 axis, reduced proinflammatory cytokines, and promoted M2 polarization. In SH-SY5Y cells with dopaminergic phenotype, Exo-Mito was associated with reactivated PI3K/Akt/mTOR signaling, preserved tyrosine hydroxylase expression, and inhibited apoptosis. Functionally, Exo-Mito improved SH-SY5Y cell and restored microglial migratory capacity, showing superior efficacy to unmodified BMSC-Exo. Mitochondria-enriched BMSC sEVs protect SH-SY5Y cells by coordinating mitochondrial quality control and modulating neuroinflammation. These findings support Exo-Mito as a promising cell-free therapeutic strategy for Parkinson's disease.",

This study investigated TIPE1's role in regulating autophagy and PTX sensitivity and developed ROS-responsive TIPE1 mRNA-loaded nanoparticles (TIPE1m NPs) as a therapeutic strategy. PTX-resistant TNBC cell lines were established, and integrated transcriptomic and proteomic analyses were performed. TIPE1 was downregulated in resistant cells, while higher TNFAIP8L1 expression in public breast cancer cohorts was associated with better survival and improved PTX response. Mechanistically, TIPE1 overexpression was associated with ubiquitination-related reduction in the stability of the small GTPase RAB7A, leading to impaired autophagic flux, increased ROS accumulation, and enhanced PTX-induced apoptosis. Conversely, TIPE1 knockdown stabilized RAB7A, enhanced autophagy, and increased PTX tolerance. ROS-responsive TIPE1m NPs were constructed to restore TIPE1 expression in resistant cells. TIPE1m NPs suppressed autophagy, increased ROS, and enhanced PTX-induced apoptosis in vitro. In PTX-resistant xenografts, combined TIPE1m NPs and PTX treatment suppressed tumor growth without obvious systemic toxicity. These findings identify the TIPE1-RAB7A-autophagy axis as a potential therapeutic target and support TIPE1 mRNA delivery as a strategy to overcome PTX resistance in TNBC.",

It is a molecular hub for cellular homeostasis and cellular responses. Within autophagy, SQSTM1 targets ubiquitinated cargo for degradation, maintaining cellular proteostasis. Structurally, SQSTM1 consists of several domains that facilitate its binding to ubiquitinated cargo, the formation of SQSTM1 aggregate inclusions, interactions with MAP1LC3/LC3, and the mediation of clearance via the autophagy pathway. Beyond its structure, post-translational modifications of SQSTM1 dynamically regulate its function within a cell. Post-translational modifications - such as phosphorylation, ubiquitination, acetylation, S-acylation, and S-nitrosylation - are crucial for regulating SQSTM1 function, localization, and interaction with autophagic components, thereby influencing SQSTM1's role in the autophagy pathway. Understanding the role of these protein modifications in modulating autophagy may provide better insight into developing therapeutic strategies for diseases with dysregulated autophagy, such as neurodegenerative diseases. This review will discuss the role of these post-translational modifications in controlling SQSTM1's localization and function in autophagy.Abbreviations: ABHD = \u03b1/\u03b2-hydrolase domain; AD = Alzheimer Disease; ALS = amyotrophic lateral sclerosis; ATG = autophagy related ; CSNK2/CK2 = casein kinase 2; HD = Huntington Disease; HDAC/KDAC = histone deacetylase/lysine deacetylase; HTT = huntingtin; KAT = lysine acetyltransferase; KEAP1 = kelch like ECH associated protein 1; KIR = KEAP1-interacting region; LIR = LC3-interacting region; LYPLA/APT = lysophospholipase/acyl-protein thioesterase; MAP1LC3/LC3 = microtubule associated protein 1 light chain 3; MEF = mouse embryonic fibroblast; mHTT = mutant huntingtin; MTORC1 = MTOR complex 1; NBR1 = NBR1 autophagy cargo receptor; NEDD4 = NEDD4 E3 ubiquitin protein ligase ; NO = nitric oxide; NFE2L2/Nrf2 = nuclear factor erythroid 2-factor 2; PAT = palmitoyl acyltransferase; PB1 = Phox-BEM1 domain; PE = phosphatidylethanolamine; PLEKHM1 = pleckstrin homology and RUN domain containing M1; PLK2 = polo like kinase 2; PRKA/PKA = protein kinase cAMP-activated; PPT1 = palmitoyl-protein thioesterase 1; RB1CC1 = RB1 inducible coiled-coil 1; SNCA/\u03b1-synuclein = synuclein alpha; SNO = S-nitrosothiol; SOD1 = superoxide dismutase 1; SQSTM1 = sequestosome 1; TARDBP/TDP-43 = TAR DNA binding protein ; TBK1 = TANK binding kinase 1; TAX1BP1 = Tax1 binding protein 1; TRIM = tripartite motif containing ; UBA = ubiquitin-associated domain; UBE = ubiquitin-conjugating enzyme; ULK1 = unc-51 like autophagy activating kinase 1; UPS =ubiquitin-proteasome system; USP8 = ubiquitin specific peptidase 8; ZDHHC = zDHHC palmitoyltransferase.",

ASOs are internalized through various endocytic mechanisms that converge on the endolysosomal pathway. Our work here aims to evaluate changes to the endolysosomal system following repeated ASO exposure. Histological examinations of nonhuman primates following repeated intrathecal administration of ASOs reveal dose-related neuronal microvesicular vacuolation in the hippocampus, cortex, and spinal cord. These changes are not associated with any neuronal degenerative changes or glial activation. Examination by electron microscopy reveals lysosomes containing stacked membranous material. We established an induced pluripotent stem cell-derived motor neuron (iPSC-MN) model that recapitulates these lysosome changes. ASO exposure did not cause any changes in iPSC-MN viability. To characterize lysosomal changes, we isolated lysosomes from iPSC-MNs after ASO treatment and quantified their protein and lipid contents by liquid chromatography-mass spectrometry. Our lipidomics studies documented increases in bis(monoacylglycerol)phosphate and lactosylceramide following ASO administration; proteomic analysis showed changes in several proteins, including decreases in four lysosomal hydrolases (Carboxypeptidase Q, \u00df-galactosidase, Cathepsin A, and \u03b1-l-Fucosidase). Altogether, this work advances our understanding of the cellular consequences following prolonged ASO administration and may guide further investigations to characterize these effects.",

Most reported pathogenic mutations are nonsense, frameshift, or splicing mutations, resulting in a premature stop codon, degradation of mutated mRNA and consequent protein haploinsufficiency. In this study, we analysed four subjects with FTD who had low plasma progranulin levels but no mutation detectable by sequencing of GRN, to disclose the underlying genetic cause of disease. Multiplex ligation-dependent probe amplification (MLPA) method was applied to search for rearrangements in GRN. Region-specific polymerase chain reaction (PCR) and Sanger sequencing were performed to define the breakpoint. Quantitative real-time PCR (qRT-PCR) on GRN mRNA and haplotype sharing analysis were also performed. MLPA revealed in all the subjects the same heterozygous deletion, and a possible common ancestor was suggested by haplotype sharing. PCR and sequencing allowed us to define the size of the deletion (3028\u00a0bp), that removes part of GRN promoter, exon 1 including the transcription start site and most of the intron 1, and the breakpoints. qRT-PCR showed reduced level of mRNA, confirming the pathological nature of the deletion. In this study, we described a GRN heterozygous gross deletion which removes the consensus sequences for transcription factors and the transcription start site, leading to a reduced levels of plasma progranulin. Our study indicates that GRN rearrangements, although not common, should be investigated in patients with FTD who show low plasma progranulin levels but no GRN mutations detectable by DNA sequencing.",

Growing evidence suggests that AD may also be considered a metabolic disorder closely associated with insulin resistance (IR). Impaired insulin signaling disrupts the PI3K/Akt and GSK3-\u03b2 pathways, resulting in synaptic dysfunction, neuronal loss, and aberrant protein phosphorylation. Moreover, IR contributes to mitochondrial dysfunction, oxidative stress, and chronic neuroinflammation within the central nervous system (CNS). These metabolic alterations, together with impaired energy homeostasis, dysregulate intracellular signaling cascades and exacerbate amyloid and tau pathology. This narrative review examines the mechanistic interplay among insulin resistance, oxidative stress, and neuroinflammation in AD, with particular emphasis on the shared cellular pathways that underlie disease progression. In addition, it summarizes emerging therapeutic strategies targeting insulin signaling, including pharmacological insulin-sensitizing agents, incretin-based therapies, lifestyle interventions, and bioactive natural compounds. The review also highlights advances in intranasal delivery strategies, which have emerged as a promising approach for enhancing brain targeting and improving therapeutic efficacy. Despite substantial progress, the precise mechanisms linking insulin resistance to neurodegeneration remain incompletely understood. Further mechanistic and translational studies are urgently required to elucidate these interactions and advance the development of effective therapeutic interventions.",

In this environment, endoplasmic reticulum stress and the unfolded protein response are activated, with the transcription factor X\u2011box binding protein 1 (XBP1) serving a key role. XBP1 not only maintains cell protein homeostasis, but also modulates the generation, metabolic adaptation and immunosuppressive function of myeloid\u2011derived suppressor cells (MDSCs). The TME and tumor\u2011derived factors, such as exosomes, remotely activate XBP1 in MDSCs, enhancing their survival and immunosuppressive capability by reprogramming lipid and glucose metabolism and upregulating the expression of arginase\u20111, inducible nitric oxide synthase, reactive oxygen species and immunosuppressive cytokines. The present review aimed to describe the TME stress\u2011XBP1\u2011MDSC\u2011immunosuppression axis, its molecular mechanisms and the role of XBP1 in MDSC heterogeneity and plasticity. Targeting XBP1 may enhance the efficacy of existing therapies, particularly immune checkpoint blockade, by alleviating MDSC\u2011mediated immunosuppression, offering a novel paradigm for understanding and reversing tumor immune escape.",

However, the roles of TMEM106B in Parkinson's disease (PD) are sparsely explored. This study aims to explore whether TMEM106B variants influence the trajectories of clinical phenotypes in PD. We longitudinally followed 241 PD patients and genotyped their single nucleotide polymorphism (SNP) of rs3173615. Patients were categorized according to rs3173615 genotypes into GG (major allele homozygotes), GC (heterozygotes), and CC (minor allele homozygotes) groups. All patients completed clinical evaluations and neuropsychological tests at baseline and every follow-up. Linear mixed-effects models were adopted to evaluate the association between rs3173615 genotypes and longitudinal disease progression in PD. At baseline, both the GG and GC groups presented less severe excessive daytime sleepiness than the CC group, and no association between the remaining clinical characteristics and the genotypes of rs3173615 was observed among the three groups. Longitudinally, compared with the CC group, the GC group manifested a significantly faster exacerbation of depression, visuospatial function and quality of life (QoL), and the GG group showed the same tendency as the GC group, though without statistical significance. TMEM106B rs3173615 is a genetic modifier for the trajectory of depression, visuospatial function and QoL in PD. Our findings suggest the potential involvement of TMEM106B in the pathogenesis of disease progression in PD, especially in the deterioration of depression, cognition and QoL.",

Current diagnostic modalities are insufficient for early detection and precise monitoring of disease progression, prompting interest in liquid biopsy-based biomarkers. Exosomal microRNAs (miRNAs) have been highlighted as significant biomarkers due to their stability and involvement in tumor progression. This narrative review evaluates current evidence regarding the diagnostic, prognostic, and therapeutic significance of exosomal and extracellular vesicle-associated miRNAs in brain tumors, particularly gliomas. Data were collected from PubMed and Google Scholar, and eight original articles published between 2016 and 2026 were included after careful screening. The findings demonstrated dysregulated expression of exosomal miRNAs, including miR-29b, miR-210, miR-301a, miR-454-3p, and miR-2276-5p, which were significantly associated with tumor grade, recurrence, survival, and treatment response. The majority of studies reported strong diagnostic performance, with receiver operating characteristic/area under the curve values ranging from 0.80 to 0.93, while mechanistic analyses implicated these miRNAs in oncogenic pathways, including PTEN/AKT signaling, hypoxia-mediated progression, autophagy regulation, and angiogenesis. Overall, exosomal miRNAs demonstrate considerable potential as noninvasive biomarkers for prognostication and therapeutic targeting, while their dynamic preoperative alterations further suggest utility in disease monitoring.",

However, therapeutic resistance within immunologically \"cold\" tumors remains a formidable barrier, necessitating multiaxial optimization across transcript architecture, neoantigen selection, delivery vector engineering, and tumor microenvironment (TME) reprogramming. This review synthesizes critical breakthroughs in mRNA biochemistry-including chemical nucleotide modifications, optimized untranslated regions, structural codon adjustments, and stringent purification methodologies-that extend transcript longevity while limiting off-target reactogenicity to maximize functional antigen expression. We evaluate multiomic neoantigen discovery workflows leveraging genomics, transcriptomics, immunoproteomics, and computational HLA-binding algorithms to refine patient-specific target selection. Next, we dissect advanced lipid nanoparticles, surface-functionalized biomaterials, and engineered extracellular vesicles optimized to enhance antigen-presenting cell tropism and lymphoid homing. We further detail how vaccine-induced cytokine fluxes actively remodel the TME, successfully reversing local immune tolerance and driving robust effector leukocyte infiltration into the tumor stroma. Specifically, we highlight the convergence of mRNA-mediated cytokine signaling and epigenetic imprinting, which cooperatively induce trained immunity for durable preventive surveillance. Finally, we delineate rational combinations with immune checkpoint blockades while addressing translational challenges: identifying predictive biomarkers, mapping presentation kinetics, and structuring adaptive clinical trial frameworks.",

Circular RNAs (circRNAs), characterized by their covalently bonded single-stranded loop configuration, have been identified as functional regulators across various cancer types. Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression.",

Aripiprazole (Ari), a first-line atypical antipsychotic, exhibits restricted clinical performance due to poor solubility, extensive hepatic metabolism, and limited brain exposure. Herein, a novel intranasal nanocarrier system was developed to enable direct and sustained delivery of Ari to the brain. Chitosan nanoparticles (Cs-NPs) surface-modified with sodium dodecyl sulfate (SDS) were prepared by the ionic gelation method and optimized using a Box-Behnken design to evaluate the effects of SDS concentration, pH, and chitosan-to-tripolyphosphate ratio on particle size, zeta potential, and drug entrapment. The optimized formulation showed a mean particle size of ~\u2009200\u00a0nm, a positive surface charge, and an entrapment efficiency of 76.98\u2009\u00b1\u20097.6%. Transmission electron microscopy confirmed spherical morphology, while the in vitro release profile exhibited an initial burst followed by a sustained phase, indicating controlled-release behavior. Pharmacokinetic evaluation using LC-MS/MS revealed significantly enhanced Ari bioavailability and brain uptake following intranasal administration of the optimized Cs-NPs compared with oral, intravenous, and intranasal solutions. Pharmacodynamic testing in a ketamine-induced psychosis rat model (open-field and forced-swim tests) demonstrated improved antipsychotic efficacy. Neurochemical analysis showed restoration of dopamine and \u03b3-aminobutyric acid levels, while histopathological findings confirmed structural improvement in hippocampal and cortical regions. Collectively, these results highlight the potential of modified Cs-NPs as a controlled-release, nose-to-brain delivery platform that enhances the therapeutic performance of Ari for the management of schizophrenia.",
"42573717": "ID: 42573717\nTitle: Selenium Nanoparticles Alleviate Intestinal Epithelial Barrier Dysfunction by Coordinating Mitochondria-lysosome Communication under Dual Organelle Stress.\nAbstract: Intestinal barrier homeostasis is closely associated with coordinated signaling between mitochondria and lysosomes. Although our previous studies demonstrated the barrier-protective effects of biogenic selenium nanoparticles (SeNPs), the inter-organelle signaling mechanisms underlying this protection under dual-organelle stress remain unclear. In the present study, we established a targeted dual-injury model in IPEC-J2 cells using chloroquine (CQ) and 2,4-dinitrophenol (DNP) to investigate the signaling events governing mitochondria-lysosome communication. Combined exposure to CQ and DNP profoundly disrupted organelle homeostasis, as evidenced by severe adenosine triphosphate (ATP) depletion, elevated intracellular reactive oxygen species (ROS) and mitochondrial superoxide production, impaired lysosomal acidification, and altered autophagy-related processes. These synergistic insults ultimately promoted apoptosis, induced tight junction disassembly, and increased epithelial permeability. Notably, SeNPs pretreatment significantly upregulated the mRNA expression of key selenoproteins, including SELENOF, SELENOS, and SELENOP, and restored the activities of the selenium-dependent antioxidant enzymes glutathione peroxidase (GPx) and thioredoxin reductase (TrxR). This restoration of antioxidant capacity attenuated intracellular ROS and mitochondrial superoxide accumulation and restored the bioenergetic support required for autophagy-related processes and lysosomal acidification. Mechanistically, restoration of intracellular redox homeostasis by SeNPs prevented oxidative stress-induced dissociation of the TBC1D15/Rab7/Fis1 complex, a key tethering axis involved in mitochondria-lysosome communication. Stabilization of this complex was accompanied by improved autophagy-lysosome homeostasis and preservation of intestinal epithelial barrier integrity. Collectively, these findings demonstrate that biogenic SeNPs preserve intestinal epithelial barrier integrity under dual-organelle stress by enhancing selenoprotein-mediated antioxidant defense, thereby stabilizing mitochondria-lysosome tethering and restoring inter-organelle communication.",
"42576524": "ID: 42576524\nTitle: The Double-Edged Sword: A Structured Narrative Review of Microglial Phenotypic Transition as a Pivotal Driver and Therapeutic Target in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder primarily involving the loss of dopaminergic neurons and pathological \u03b1-synuclein (\u03b1-syn) aggregation. A pivotal feature of PD pathogenesis is the dual role of microglia, which shifts from maintaining neuronal homeostasis to driving neuroinflammation and neurodegeneration. The mechanisms underlying this functional transition and its consequences for disease progression require a comprehensive synthesis. A structured PubMed search was performed using the keywords \"Parkinson's disease\", \"microglia\", \"neuroinflammation\", \"\u03b1-synuclein\", \"polarization\", \"tunneling nanotubes (TNTs)\", \"NF-\u03baB\", and \"NLRP3\". Relevant combinations of these terms were also used. A total of 2952 records were retrieved up to December 2025. Of these, 147 studies were included based on relevance to microglial polarization, neuroinflammation, \u03b1-syn-related pathology, and intercellular communication mechanisms. In early PD stages, microglia exert neuroprotective effects by transferring excess neuronal \u03b1-syn via TNTs, delivering healthy mitochondria, and clearing \u03b1-syn through autophagy. With disease progression, accumulated \u03b1-syn promotes microglial polarization toward the M1 phenotype. This shift activates TLR2/4, TREM2, MHCII, and RAGE receptors, triggering NF-\u03baB/NLRP3 pathways, releasing pro-inflammatory cytokines, and generating NOX2-derived ROS. The resulting neuroinflammatory cascade not only damages dopaminergic neurons directly but also disrupts astrocyte function and blood-brain barrier integrity, creating a self-perpetuating cycle of inflammation and neurodegeneration. These findings support dysregulated microglial polarization as an important component of PD pathobiology, but the available evidence remains weighted toward preclinical models. Future work should better define the timing, heterogeneity, and clinical measurability of microglial state transitions before microglia-targeted strategies can be translated with confidence. Microglial polarization may represent a potential therapeutic direction in Parkinson's disease, although further mechanistic and clinical validation and more precise biomarker definition remain necessary.",
"42576648": "ID: 42576648\nTitle: p62/SQSTM1: From an autophagy receptor to a condensate organizer of selective autophagy and stress signaling.\nAbstract: Upon exposure to stress, cells activate a variety of stress-response and quality-control mechanisms to maintain homeostasis. Dysregulation of these processes is implicated in numerous diseases, including cancer, liver disorders, and neurodegenerative diseases. p62/Sequestosome 1 (SQSTM1) is a multifunctional protein that plays a central role in protein homeostasis and stress responses by regulating autophagy and signal transduction pathways. Through its multiple protein-interacting domains, p62 functions both as a scaffold for selective autophagic degradation and as a signaling hub. Since our previous review of p62 a decade ago, substantial progress has been made in elucidating its molecular functions and physiological roles. Notably, p62 undergoes liquid-liquid phase separation with ubiquitinated proteins to form membraneless condensates, termed p62 bodies, when cells are exposed to proteotoxic stress. By sequestering specific proteins, p62 bodies act as platforms for autophagy-dependent degradation and stress signaling. These findings have substantially revised our view of p62 function, which was previously considered primarily as a receptor simply linking ubiquitinated substrates to autophagic membranes and connecting signaling molecules. This conceptual shift from one-to-one molecular interactions to multivalent, multimolecular, higher-order assemblies has fundamentally redefined the functional landscape of p62. In this review, we highlight how p62 bodies integrate selective autophagy and stress signaling, with a particular emphasis on their emerging roles in disease pathogenesis and their potential as therapeutic targets.",
"42576802": "ID: 42576802\nTitle: Mechanism of Autophagic Extracellular Vesicles Revealed.\nAbstract: Recent work by Mao and colleagues identifies a distinct class of small extracellular vesicles, termed autophagic extracellular vesicles (AEVs), generated from amphisomes upon autophagy induction. In this commentary, we discuss how this study provides important mechanistic insight into the coupling between autophagy and secretion. AEVs are molecularly and functionally distinct from canonical exosomes, being enriched in autophagy-related components such as LC3 and p62, and dependent on core ATG machinery for their biogenesis. Notably, their secretion is enhanced by autophagy induction and contributes to intercellular communication, particularly in the context of viral infection. These findings position amphisomes as critical sorting hubs that direct cargo toward either degradation or secretion, thereby integrating autophagic and endolysosomal pathways. We further highlight how these results intersect with prior evidence implicating SNARE-dependent mechanisms, including VAMP7 and stress-responsive regulators such as GRASP55, in unconventional secretion. Finally, we discuss key unresolved questions, particularly the mechanisms underlying the generation of small intraluminal vesicles within amphisomes and the role of ESCRT machinery in this process. Overall, the identification of AEVs adds a new layer of complexity to extracellular vesicle biology and opens new avenues for understanding how autophagy contributes to intercellular signaling in health and disease.",

Although \u03b1-syn aggregation is considered central to PD pathogenesis, increasing evidence suggests that \u03b1-syn abundance may be as important as its conformational state. Genetic studies have demonstrated an SNCA dosage effect, with gene duplication and triplication associated with progressively more severe familial PD phenotypes. Complementary evidence indicates that dysfunction of protein clearance pathways, particularly the autophagy-lysosome system, promotes intracellular \u03b1-syn accumulation and increases its neurotoxic potential. In this review, we propose \u03b1-syn multiplication as an integrative framework for interpreting PD pathogenesis. This concept extends beyond SNCA copy-number variation to encompass processes that increase the effective \u03b1-syn burden within neurons or across neural networks, including increased gene expression, impaired degradation, disrupted proteostasis, and pathological propagation. We summarize \u03b1-syn structural dynamics and the concentration-dependent distribution of monomeric, oligomeric, and fibrillar species. We then review evidence from SNCA gene-dosage studies and examine the role of the autophagy-lysosome pathway in regulating \u03b1-syn homeostasis, with particular emphasis on recent experimental findings demonstrating that autophagy deficiency exacerbates \u03b1-syn accumulation and neurodegeneration in human \u03b1-syn bacterial artificial chromosome transgenic mice. Collectively, the available genetic, biochemical, and experimental evidence supports a model in which the balance between \u03b1-syn production and clearance influences disease progression alongside protein misfolding. The interaction between increased protein burden and impaired clearance capacity provides a unifying mechanism linking familial and sporadic forms of PD. We propose that \u03b1-syn multiplication offers an integrative framework for understanding PD pathogenesis, provides a quantitative perspective on disease heterogeneity, and highlights therapeutic opportunities aimed at reducing \u03b1-syn burden and restoring proteostatic balance.",

Methotrexate, a folic acid analogue used in cancer and autoimmune treatments, impairs spermatogenesis via oxidative stress and apoptosis. Twenty-four male Wistar rats were randomized into four groups: Control (normal saline, 35 days), MTX (0.30 mg kg-1, gavage, three times per week, 35 days), MTX + RJ (0.30 mg kg-1 MTX + 0.10 mg kg-1 RJ, gavage, three times per week, 35 days), and RJ (0.10 mg kg-1, gavage, three times per week, 35 days). After 35 days, rats were euthanized and testicular tissue was analyzed via histopathology, immunohistochemistry for LC3-I/II expression in germ cells and qRT-PCR for mRNA expression of autophagy-related genes (Beclin-1, Atg7, LC3-I). Histopathological findings revealed that MTX caused severe interstitial edema, coagulative necrosis and disrupted spermatogenesis with reduced seminiferous tubule diameter, epithelial thickness, tubular differentiation index (TDI) and spermiogenesis index. Co-administration of RJ significantly improved seminiferous tubule morphology, diameter, epithelial thickness, TDI and spermiogenesis index. Immunohistochemistry showed a significant increase in LC3-I/II+ germ cells (spermatogonia, spermatocytes, spermatids) in the MTX group which was markedly reduced in the MTX + RJ group. Similarly, qRT-PCR analysis demonstrated elevated mRNA levels of Beclin-1, Atg7, and LC3-I in the MTX group which were significantly reduced in the MTX + RJ group. These findings suggested that RJ mitigated MTX-induced testicular damage by reducing oxidative stress and autophagy, thereby, preserving spermatogenesis and testicular integrity.",

Lf-LNT-PEG-CS-NCs were prepared, optimized, and characterized for particle size, entrapment efficiency, coating efficiency, and release behavior. Ex vivo permeation, cellular uptake, cytotoxicity, apoptosis, pharmacokinetic, and biodistribution studies were performed using U87 MG cells and Wistar rats. The optimized NCs exhibited a particle size of 205.3\u2009\u00b1\u200911\u2009nm, entrapment efficiency of 71.52\u2009\u00b1\u20090.98%, and coating efficiency of 92.42\u2009\u00b1\u20090.94%, with sustained drug release for 36\u2009h. The permeation increased by 2.86-fold, while cellular uptake reached 78.38\u2009\u00b1\u20093.76%. Treatment significantly reduced U87 MG cell viability (84.21\u2009\u00b1\u20092.75% inhibition) and induced apoptosis with 64.55\u2009\u00b1\u20092.28% G0/G1 arrest, accompanied by reduced COX-2 (55.81\u2009\u00b1\u20092.91%) and Bcl-2 (59.65\u2009\u00b1\u20091.95%) expression and increased caspase-3 (73.10\u2009\u00b1\u20092.91%). Intranasal administration achieved a CSF Cmax of 46.72\u2009\u00b1\u20093.78\u2009\u03bcg/mL and brain accumulation of 42.83\u2009\u00b1\u20092.59\u2009\u03bcg/mL. LRP-1-targeted Lf-LNT-PEG-CS-NCs significantly enhanced intranasal brain delivery, cellular uptake, and apoptotic activity of LNT, demonstrating a promising noninvasive platform for targeted GBM therapy.",
"42580438": "ID: 42580438\nTitle: Current Clinical Evidence on Nose-to-Brain Drug Delivery.\nAbstract: Intranasal delivery is increasingly recognised as a promising strategy for direct drug transport to the brain via the nose-to-brain pathway, bypassing the blood-brain barrier and improving therapeutic efficacy. This approach has shown potential in the treatment of neurological disorders, including Alzheimer's disease, Parkinson's disease, epilepsy, multiple sclerosis, and acute psychiatric conditions, as well as in emergencies such as anxiety attacks and migraine episodes. Recent clinical studies investigating intranasal formulations of rivastigmine, insulin, and olanzapine, among other drugs, have provided encouraging evidence supporting the clinical translation of this delivery strategy. In addition, FDA-approved intranasal products indicated for central nervous system disorders, including diazepam and midazolam for seizure management, and triptans for migraine, demonstrate the growing clinical relevance of intranasal drug delivery. Both preclinical and clinical studies have reported encouraging outcomes, particularly when intranasal delivery is combined with nanoformulations and specialised delivery devices designed to enhance olfactory deposition. Intranasal administration is non-invasive, painless, and may improve patient adherence while enhancing brain bioavailability. Nevertheless, further well-designed clinical studies are required to establish the long-term safety, efficacy, and clinical applicability of this delivery strategy.",

While protective autophagy is often suppressed in sepsis, the underlying mechanisms remain unclear. This study investigated whether the SOX4/IGF2BP3/TRIB3 pathway contributes to liver dysfunction by suppressing cytoprotective autophagy. In vitro experiments were performed using LPS-treated mouse primary hepatocytes, with measurements of SOX4, IGF2BP3, and TRIB3 expression by RT-qPCR and Western blot, cell viability by CCK-8, autophagic flux by mRFP-GFP-LC3 probe, and molecular interactions via luciferase reporter, ChIP, RIP, and RNA stability assays. In vivo, a murine sepsis model was established by cecal ligation and puncture. Clinically, mRNA levels of SOX4, IGF2BP3, and TRIB3 were measured in peripheral blood mononuclear cells from sepsis patients and correlated with clinical scores and outcomes. We found that the SOX4/IGF2BP3/TRIB3 axis was upregulated in septic hepatocytes, and its knockdown alleviated LPS-induced injury and impaired autophagic flux. SOX4 transcriptionally activated IGF2BP3, which stabilized TRIB3 mRNA in an m6A-dependent manner. Rescue experiments confirmed that this axis exacerbated LPS-induced hepatocyte injury by suppressing autophagic flux. Inhibition of SOX4 or IGF2BP3 alleviated liver injury and improved survival in septic mice. Clinically, circulating SOX4, IGF2BP3, and TRIB3 levels stratified the presence and severity of SALI and provided high-precision prognostic information. In conclusion, in SALI, SOX4 upregulates IGF2BP3, which stabilizes TRIB3 mRNA in an m6A-dependent manner. Accumulation of TRIB3 protein suppresses cytoprotective autophagy, ultimately leading to hepatocyte death and liver dysfunction.",

However, the activation profile of cochlear microglia-like cells (MLCs) and their mechanistic role in age-related hearing loss (ARHL) remain poorly defined. Here, we show that MLCs are robustly activated in the cochlea of aged mice, and that pharmacologic depletion of cochlear MLCs significantly attenuates ARHL progression. To dissect the mechanisms underlying MLC-driven cochlear damage in ARHL, we leveraged the single-cell transcriptomic landscape of the aged mouse cochlea previously generated by our research group, and conducted the related functional validation. We identified prominent age-related alterations in cochlear MLCs, and revealed that AAV-mediated (via posterior semicircular canal microinjection) upregulation of progranulin (GRN) in MLCs mitigates aging-associated oxidative stress damage in the cochlea. Collectively, our work demonstrates that targeting GRN signaling in cochlear MLCs alleviates aging-related oxidative stress in the cochlea, and thereby delays ARHL progression.",

An ICH-induced PHH rat model was established. Rats were treated with varying doses of dapagliflozin to evaluate dose-response neuroprotection. To elucidate the underlying molecular pathways, selective autophagy and MEK inhibitors were subsequently administered. Dapagliflozin dose-dependently attenuated ventricular enlargement, improved neurological deficits, and reduced neuroinflammation post-ICH. Crucially, autophagy inhibition reversed these benefits, concurrently impairing glymphatic clearance, reducing cerebral blood flow (CBF), and disrupting neurovascular unit (NVU) integrity. Furthermore, MEK inhibition counteracted the dapagliflozin-induced enhancement of autophagy, confirming the MEK/ERK pathway's regulatory role. Dapagliflozin mitigates PHH by activating the MEK/ERK pathway to enhance autophagy. This mechanistic axis is essential for maintaining NVU integrity, improving glymphatic permeability, and increasing CBF perfusion, presenting SGLT2 inhibition as a promising translational therapy for ICH complications.",
"42586468": "ID: 42586468\nTitle: Cobalt oxide nanoparticles induce neurodevelopmental toxicity through ferritinophagy-mediated ferroptosis: Evidence from zebrafish and cell models.\nAbstract: Cobalt oxide nanoparticles (Co3O4 NPs) are widely used in lithium batteries and semiconductors, and are often detected in water, soil, and occupational environments. While cobalt ions are linked to neurodegenerative diseases, the neurodevelopmental toxicity of Co3O4 NPs remains poorly understood. Ferroptosis, a process regulated by iron homeostasis, can be triggered by ferrous overload through ferritinophagy. This study explores how Co3O4 NPs induce ferritinophagy and their role in neurodevelopmental toxicity. Zebrafish larvae exposed to Co3O4 NPs at concentrations of 0, 5, and 50\u202fmg/L for up to 120\u202fh post-fertilization (hpf) exhibited dose-dependent developmental toxicity, including delayed hatching, increased malformations, and impaired motor behavior. Transgenic zebrafish models demonstrated neuronal shortening, reduced fluorescence, and altered neurotransmitter profiles, as supported by liquid chromatography-tandem mass spectrometry. Co3O4 NPs induced oxidative stress, leading to iron overload, lipid peroxidation (elevated MDA, depleted glutathione), and ferritinophagy activation, as evidenced by changes in genes and proteins related to iron metabolism (trf, fpn, slc7a11) and ferroptosis (GPX4, ACSL4, FTH1, NCOA4). Ferritinophagy was further confirmed using autophagy inhibitors, demonstrating its role in neurotoxicity. Additionally, Vitamin E (d-\u03b1-tocopherol), a lipid-soluble antioxidant that suppresses lipid peroxidation, reduced neurodevelopmental abnormalities, supporting that Co3O4 NP-induced toxicity occurs through ferritinophagy-mediated ferroptosis, leading to neurotransmitter dysregulation. These findings were corroborated in human neuroblastoma cells (SH-SY5Y/SK-N-SH). In conclusion, Co3O4 NPs disrupt iron homeostasis, activate ferritinophagy, and induce ferroptosis, resulting in neurotransmitter dysregulation and neurodevelopmental toxicity. These results provide new insights for assessing the neurodevelopmental toxicity and environmental risk of Co3O4 NPs and similar nanomaterials.",
"42587750": "ID: 42587750\nTitle: The E. coli High-Pathogenicity Island Downregulates PI3K/Akt/mTOR Expression and Induces Autophagy in the Mouse Intestine.\nAbstract: The high-pathogenicity island (HPI) is a major virulence determinant in pathogenic Escherichia coli (E. coli), contributing to severe inflammation and tissue damage. Autophagy plays a critical role in clearing intracellular pathogens and modulating inflammation, but whether HPI manipulates this process remains unknown. Here, using a swine-pathogenic E. coli strain and its HPI-deficient mutant (\u0394irp2) generated by CRISPR/Cas9, we investigated the interplay between HPI and autophagy in RAW264.7 macrophages and a mouse intestinal infection model. We found that HPI+ infection induced autophagic activation, as evidenced by increased LC3 puncta (immunofluorescence), upregulated Beclin-1 and autophagy-related gene mRNA levels (qPCR), and downregulated phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) expression at both mRNA (qPCR) and protein (immunohistochemistry) levels. In a mouse model, HPI+ infection upregulated intestinal Microfold (M) cell markers and secretory Immunoglobulin A (IgA), triggered robust production of pro-inflammatory cytokines, and induced more severe tissue pathology than the HPI-deficient mutant. Pharmacological activation of autophagy with rapamycin alleviated HPI-induced inflammation and injury, whereas inhibition of autophagy by 3-methyladenine (3-MA) or Beclin-1 silencing exacerbated damage. These findings suggest that HPI induces autophagy, but the endogenous autophagic response is insufficient to counteract HPI-induced pathology; pharmacological enhancement of autophagy partially alleviated this insufficiency and reduced tissue damage. Notably, Beclin-1 knockdown blunted HPI-induced upregulation of PI3K and autophagy-related genes, suggesting a role for Beclin-1 in the transcriptional regulation of these responses. In conclusion, HPI simultaneously exerts direct pro-inflammatory effects and induces Beclin-1-dependent autophagy. Enhancing this autophagic response pharmacologically, rather than relying on the endogenous level triggered by HPI alone, limits excessive tissue damage. Thus, boosting autophagy may represent a promising therapeutic strategy against HPI-bearing pathogenic E. coli infections.",
"42587819": "ID: 42587819\nTitle: Autophagy at the Crossroads of Protein and RNA Toxicity in Repeat Expansion Cerebellar Ataxias.\nAbstract: Repeat expansion cerebellar ataxias comprise a genetically and mechanistically heterogeneous group of neurodegenerative disorders unified by the pathological expansion of short tandem repeats (STRs) beyond a disease-causing threshold. Depending on their genomic localization, these expansions can lead to toxic protein gain-of-function, as in polyglutamine (polyQ) cerebellar ataxias, or to RNA-mediated toxicity and repeat-associated non-AUG (RAN) translation, for which recent evidence supports a major pathogenic role in non-coding spinocerebellar ataxias (SCAs). Despite these distinct upstream mechanisms, disruption of neuronal homeostasis occurs through converging pathogenic processes, including proteostasis impairment, transcriptional dysregulation, and mitochondrial dysfunction, leading to progressive neuronal loss. Importantly, impaired autophagy has been consistently reported across multiple repeat expansion ataxias, including both dominant SCAs and recessive conditions, such as Friedreich's ataxia, suggesting that impairment of this pathway may represent a shared downstream event in disease progression. Indeed, in polyQ cerebella ataxias, the accumulation of misfolded and aggregation-prone proteins places a substantial burden on cellular quality control systems, particularly the ubiquitin-proteasome system and autophagy. Similarly, in non-coding SCAs, toxic RNA species and RAN-derived peptides might interfere with protein clearance mechanisms and contribute to cellular stress. In this review, we will discuss the evidence supporting autophagy impairment as a convergent pathogenic pathway in repeat expansion cerebellar ataxias.",

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations.",

Selenium (Se), an essential trace element critical for kidney health, primarily exerts its physiological roles via selenoproteins; among them, membrane-bound selenoproteins strategically localized at the endoplasmic reticulum and plasma membrane, have emerged as potential molecular links in Se-mediated protection. In this study, Hyline chicken models (treated with 350.00 mg/L Pb or/and 1.00 mg/kg Se) and HK-2 cell models (treated with 200 \u03bcM Pb or/and 2.5 \u03bcM Se) were established to investigate the protective mechanism of Se to Pb poisoning in kidneys, with emphasis on membrane-bound selenoproteins and kidney aging. Results showed that Pb significantly decreased (p < 0.05) membrane-bound selenoproteins and induced kidney aging. Inflammation and autophagy were involved, as Pb significantly increased (p < 0.05) pro-inflammatory cytokines interleukin-4 (IL-4) and interleukin-12\u03b2 (IL-12\u03b2), and autophagy-related genes autophagy related 5 (ATG5), BCL2 interacting coiled coil protein 1 (Beclin 1), and microtubule-associated protein 1A/1B-light chain 3 (LC3-II) while significantly suppressing (p < 0.05) interleukin-2 (IL-2) and mammalian target of rapamycin (mTOR). Se had a relieving effect on it, as evidenced by significantly reversing (p < 0.05) the changes in the above indicators. Interestingly, Selenoprotein T (SELENOT), as a hub membrane-bound selenoprotein, is sensitive to Pb poisoning (Pb exposure decreased SELENOT mRNA expression to 56%, 34%, and 19% of the control levels at 30, 60, and 90 days, respectively). Knockdown of SELENOT aggravated Pb-induced inflammation, autophagy, and cellular senescence, meaning that SELENOT protected against kidney aging via suppressing inflammation and autophagy under Pb stress. These findings establish membrane-bound selenoproteins as essential molecular hubs that orchestrate inflammation resolution and autophagy in Se's antagonism against Pb-induced kidney aging, highlighting promising therapeutic targets for nephropathy.",
"42589242": "ID: 42589242\nTitle: Differential Effects of PERK and IRE1\u03b1 Silencing on Expression of Apoptosis and Autophagy Markers in T-Lymphoblastic Leukemia MOLT-3 Cells.\nAbstract: Cancer cells are able to survive under conditions of high endoplasmic reticulum (ER) stress by activating the adaptive unfolded protein response (UPR), which is closely linked with autophagy. On the other hand, excessive and prolonged ER stress leads to apoptosis. However, the relationships between different UPR branches and apoptosis or autophagy vary in cancer cells of different origins and depend on the extent and nature of the stress signal. This study was designed to establish the role of ER stress sensors protein kinase RNA-like endoplasmic reticulum kinase (PERK) and inositol-requiring enzyme 1 (IRE1\u03b1) in apoptosis or autophagy signaling in T-lymphoblastic leukemia MOLT-3 cells via the RNA interference method. The cells were transfected with small interfering RNAs (si-PERK, si-IRE1\u03b1, or si-Cont) for 6 h and further cultured under normal conditions for 72 h to provide an insight into chronic effects of the gene silencing. The expression of apoptosis and autophagy effectors at the mRNA and protein levels was compared using RT-PCR and Western blot assays, respectively. Transfection of the cells with PERK siRNA led to a significant decrease in PERK protein and gene expression, and decreased phosphorylation of its downstream effector eukaryotic initiation factor 2\u03b1 (eIF2\u03b1). PERK silencing was accompanied by activation of apoptosis-related genes and proteins-BCL2-associated X (Bax), caspase-3, C/EBP homologous protein (CHOP), while the levels of autophagy markers (Unc-51 like autophagy activating kinase 1 (ULK1), Beclin-1, and microtubule-associated proteins 1A/1B light chain 3 (LC3A/B)) remained stable. In contrast, treatment of the cells with si-IRE1\u03b1 reduced the content of IRE1\u03b1, X-box-binding protein 1 (sXBP1), and glucose-regulated protein 78 (GRP78) proteins, but increased ERN1 gene expression. IRE1\u03b1 RNA interference did not affect the levels of the pro-apoptotic marker Bax, but suppressed caspase-3, CHOP, c-Jun N-terminal kinase (JNK), and autophagy signaling molecules (ULK1, Beclin-1, LC3A/B) at both the transcriptional and translational levels. These results indicate that the PERK pathway is an important contributor to the survival of MOLT-3 cells under basal ER stress, while PERK depletion compromises the resistance of cells to UPR-mediated apoptosis. The IRE1\u03b1 UPR branch is directly linked with autophagy-dependent signaling, although IRE1\u03b1 knockdown exerted a more complicated influence on the cells, probably via activation of multiple pro-death and compensatory pro-survival regulatory mechanisms.",
"42589286": "ID: 42589286\nTitle: Exercise and Ferroptosis in Neurodegenerative Diseases: Direct Evidence, Mechanistic Links, and Translational Gaps.\nAbstract: Ferroptosis is an iron-dependent form of regulated cell death characterized by iron dyshomeostasis, glutathione depletion, glutathione peroxidase 4 dysfunction, and excessive lipid peroxidation. Exercise is a safe and accessible non-pharmacological intervention with broad neuroprotective potential, but the evidentiary basis linking exercise specifically to ferroptosis is uneven. Only a limited subset of studies directly combines an exercise intervention with ferroptosis-related outcomes in neurodegenerative models; much of the proposed pathway architecture is inferred from pharmacological, cellular, observational, or acute neurological injury studies. This review therefore separates direct exercise evidence from exercise-related supporting evidence and non-exercise mechanistic evidence. The most directly relevant findings, concentrated largely in aerobic exercise models, show exercise-associated changes in brain iron handling, the cystine/glutamate antiporter-glutathione peroxidase 4 antioxidant system, and lipoxygenase-dependent lipid peroxidation. Supporting studies suggest additional peripheral-to-central mechanisms involving muscle-derived exosomes, exercise-associated changes in systemic and cerebral iron handling, and inflammatory regulation. Bone marrow hematopoiesis, adult neurogenesis, synaptic plasticity, and astrocyte-controlled iron traffic are incorporated as biologically plausible but incompletely tested links. Evidence for resistance training, high-intensity interval training, mind-body exercise, and human disease remains insufficient. The central limitation is therefore not pathway plausibility but the scarcity of exercise-specific causal experiments demonstrating that ferroptosis suppression is required for neuroprotection.",

A prediabetic mouse model was established, with 18 mice randomly assigned to three groups: model control group, grape exosome treatment group, and antioxidant nutrient supplementation group. Therapeutic efficacy was assessed using fasting plasma glucose (FPG) and homeostasis model assessment of \u03b2-cell function (HOMA-\u03b2). Intestinal content metabolites were profiled via both untargeted ultra-high performance liquid chromatography coupled with orbitrap electrospray mass spectrometry (UHPLC-OE-MS) and targeted metabolomics analyses. Grape exosomes effectively mitigated prediabetes progression. Untargeted metabolomics revealed 1222 downregulated and 425 upregulated metabolites in the grape exosome group relative to the model control group, among which riboflavin (upregulated) was potentially associated with amino acid metabolism. Targeted metabolomics identified 23 upregulated and 41 downregulated metabolites, with glycine showing a significant elevation. Notably, both the grape exosome group and antioxidant nutrient supplementation group exhibited increased glycine levels and shared enriched metabolic pathways, including D-glutamine and D-glutamate metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, as well as valine, leucine, and isoleucine biosynthesis. Integrated untargeted and targeted metabolomics analysis demonstrates that grape exosomes ameliorate diabetes-related metabolic disorders and slow the progression of prediabetes, indicating that grape-derived exosomes have great potential as a functional intervention agent for early glucose metabolism dysfunction.",

How the predicted regulatory potential of these miRNAs differs among the milks of different animals most relevant to human nutrition has not been systematically compared. Here, we performed an integrative in silico analysis of publicly available small-RNA sequencing data from 29 milk and milk-cell samples of human, cow, goat, and donkey origin. miRNAs were quantified against human (hsa) miRBase references-thereby restricting the analysis to evolutionarily conserved miRNAs with human orthologs-and their predicted effect on the human transcriptome was modeled by integrating predicted (mirDIP database) and experimentally supported (TarBase v9 database) miRNA-target interactions into a per-gene, per-species weighted targeting score. Because miRNAs act predominantly as repressors, this score is read as a prediction of which genes would be post-transcriptionally down-regulated in a recipient. miR-148a-3p dominated the exosomal spectrum of all four species (human, cow, goat, and donkey; \u224821.5% of pooled abundance), and the twenty most abundant miRNAs accounted for roughly three quarters of the signal. Of 4577 robustly targeted genes, a 1809-gene conserved \"pan-milk\" core showed the highest cross-species targeting and was enriched for transcriptional regulation, PI3K-Akt, MAPK, and TGF-\u03b2/SMAD signaling, autophagy and-strikingly-the components of the RNA-interference machinery itself. Species-restricted gene sets recapitulated biologically plausible programs, including a human-biased neuronal/axon-guidance and chromatin module, a donkey-biased transcriptional, epithelial, and immune (CD47) module, and a ruminant lipid/cholesterol and insulin-mTOR module. Across categories, we observed a reproducible confidence-exclusivity trade-off. We emphasize that these results are computational predictions that assume dietary miRNA uptake and do not constitute experimental validation. We provide the complete targetome as a hypothesis-generating resource to prioritize candidate genes, pathways, and milk types for future functional, nutritional, and epigenetic investigation. Across the 29 samples from the four species, miRNA composition segregated by species (silhouette width = 0.82, a cluster-separation measure ranging from -1 to 1, with values near 1 indicating well-separated groups) and the category structure exceeded a permutation null, indicating that the between-species signal is robust to differences in dataset origin and milk state.",

Increasing evidence indicates that these vesicles participate in diverse physiological and pathological processes, including immune regulation, tissue repair, tumor progression, neurodegeneration, and cardiovascular homeostasis. Their distinctive biological properties have consequently generated considerable interest in their development as diagnostic tools, therapeutic agents, and drug-delivery platforms. Recent progress in exosome biology and biogenesis, together with technological advances in vesicle isolation, characterization, engineering, and large-scale production, has accelerated their preclinical development and early clinical translation.

"42591088": "ID: 42591088\nTitle: Chlorogenic acid inhibits intestinal lipid uptake and promotes adipose lipid catabolism via epithelium-derived exosomes in ob/ob mice.\nAbstract: Chlorogenic acid has been widely reported to regulate lipid metabolism and alleviate obesity; however, its effects on intestinal lipid uptake and adipose tissue catabolism, as well as the underlying mechanisms, remain incompletely understood. In the present study, diabetic ob/ob mice were treated with chlorogenic acid, which significantly improved metabolic parameters, including body weight, serum triglyceride levels, glucose tolerance, and insulin sensitivity. Notably, chlorogenic acid reduced intestinal lipid content and downregulated the expression of genes involved in lipid transportation. Concurrently, epididymal adipose tissue weight was decreased, accompanied by enhanced expression of genes associated with lipid catabolism. Mechanistically, chlorogenic acid decreased triglyceride level and suppressed PPAR\u03b3 protein expression in IPEC-J2 cells. Activation of PPAR\u03b3 attenuated the inhibitory effects of chlorogenic acid on lipid accumulation, indicating a critical role of PPAR\u03b3 signaling. In addition, chlorogenic acid altered the concentration of epithelial cell-derived exosomes. These exosomes reduced triglyceride levels and modulated the expression of lipid metabolism-related genes in 3T3-L1 cells. Collectively, our findings suggest that chlorogenic acid may exert metabolic benefits, at least in part, through a coordinated intestine-adipose axis and provide preliminary evidence supporting a potential role for exosome-mediated inter-organ communication in the regulation of lipid homeostasis.",

Here, we investigate whether the CT Receptor plays a role in cancer cell survival. In cancer cell lines, knockdown of CALCR disrupts the cell cycle and induces apoptosis, supporting an essential pro-survival role. The CALCR gene produces three main transcripts in humans, of which Transcript 1 encodes CALCRb mRNA including exon 10 and is translated into the CTb Receptor isoform, and Transcripts 2 and 3 which are translated into the CTa Receptor. CALCRb expression is conserved across a diverse range of mammalian species. We examined the expression of all CT Receptor isoforms (CALCRtotal) and CALCRb expression in four high-grade glioma stem-like cell lines and in U-87 MG glioblastoma cells. Using qPCR, we observed stable levels of both CALCRtotal and CALCRb expression under conditions of autophagy or apoptosis, consistent with a requirement for CALCRb in cell survival. As alternative splicing (AS) of key genes in cancers confers tumour resilience, we investigated AS of CALCR transcript 2 using long-read nanopore sequencing. Unexpectedly, we discovered a novel AS event causing inclusion of exon 10 within Transcript 2 in all glioblastoma cell lines investigated. This finding, together with stable CALCRb expression under cellular stress and the finding by other groups confirming that knockdown of CT Receptor compromises cell survival, implicates the CTb Receptor as a potential oncoprotein.",

Their intrinsic healing capacity is limited by pathological conditions such as local hypoxia, oxidative stress, and secondary fatty infiltration, which prevent spontaneous restoration of the native four-zone gradient architecture. As a result, functional tissue is often replaced by fibrovascular scar tissue with inferior mechanical properties. Because surgical repair alone cannot precisely recreate this complex interface, highly biomimetic tissue-engineered regenerative strategies have emerged as a promising alternative. Beginning with the anatomy of the rotator cuff and the key challenges in treating rotator cuff injuries, this review summarizes the spatiotemporal complexity, physiological vulnerability, and rehabilitation challenges of the TBI. It further discusses the structural composition, fabrication methods, mechanisms of action, and clinical applications of tissue-engineered strategies for TBI regeneration. These approaches use scaffolds based on hydrogels, decellularized matrices, polymers, collagen, and nanoparticles, which can be functionally engineered through graded architectures, aligned structures, mineralization cues, and tailored interfacial properties. In parallel, active components such as stem cells, exosomes, and bioactive factors can be incorporated to recreate a three-dimensional microenvironment that supports tissue regeneration, attenuates inflammation, regulates bone metabolic homeostasis, and promotes vascular regeneration. Although substantial progress has been made in tissue-engineered repair of rotator cuff injuries, future studies should place greater emphasis on digitally enabled and coordinated scaffold design, more robust safety assessment, and quantitative evaluation of therapeutic efficacy. Mechanistic studies and translational research will also be essential to bridge the gap between basic research and clinical application.",
"42594755": "ID: 42594755\nTitle: Shikonin inhibits bladder cancer progression by targeting deoxyribonuclease 2 to suppress reticulon 3-dependent endoplasmic reticulum autophagy.\nAbstract: Bladder cancer (BCa) is a prevalent urinary malignancy with unmet clinical therapeutic needs. Shikonin, a natural anti-tumor compound, exerts anti-BCa activity, yet its direct molecular target and underlying mechanism remain undefined. This study aimed to identify the direct target of shikonin in BCa and to elucidate the mechanism by which shikonin suppresses tumor progression. The anti-BCa effects of shikonin were assessed in vitro and in vivo. Drug affinity responsive target stability (DARTS) combined with 4D quantitative proteomics identified shikonin's direct target, which was validated by molecular docking and cellular thermal shift assay (CETSA). Gain- and loss-of-function experiments and ER-phagy-related assays elucidated the underlying molecular mechanism. Shikonin inhibited BCa cell proliferation, migration, invasion and induced senescence in vitro, and suppressed tumor growth in vivo with no obvious toxicity. Deoxyribonuclease 2 (DNASE2) was identified as shikonin's direct target; shikonin promoted DNASE2 ubiquitination and degradation without altering its mRNA level. DNASE2 was highly expressed in BCa and correlated with poor prognosis, and its knockdown mimicked and enhanced shikonin's anti-BCa effects. Mechanistically, shikonin targeted DNASE2 to downregulate Reticulon 3 (RTN3), thereby inhibiting RTN3-dependent endoplasmic reticulum autophagy (ER-phagy) in BCa. This study first identifies DNASE2 as the direct target of shikonin in BCa, and reveals that shikonin exerts anti-BCa activity by promoting DNASE2 ubiquitination/degradation to inhibit the DNASE2/RTN3 axis-mediated ER-phagy. The DNASE2/RTN3 axis is a novel ER-phagy regulatory node in BCa, providing a potential therapeutic target for BCa treatment.",
"42595252": "ID: 42595252\nTitle: URG7-Driven Homeostatic Adaptation Protects SH-SY5Y Cells from 6-OHDA Neurotoxicity.\nAbstract: Parkinson's disease (PD) is characterized by progressive dopaminergic neurodegeneration associated with oxidative stress, mitochondrial dysfunction, endoplasmic reticulum (ER) stress, and impaired proteostasis. In this study, we investigated the role of Up-Regulated Gene 7 (URG7), an ER-resident protein, in regulating cellular stress responses in SH-SY5Y neuroblastoma cells exposed to 6-hydroxydopamine (6-OHDA), a widely used in vitro model of PD. URG7 overexpression significantly enhanced activation of the adaptive unfolded protein response (UPR), particularly the PERK/eIF2\u03b1/ATF4 pathway, while limiting ER stress-induced damage. Moreover, URG7 promoted protein quality control mechanisms by stimulating both the ubiquitin-proteasome system and autophagy, as demonstrated by increased ubiquitination, proteasome activity, and upregulation of Beclin-1 and LC3-II. URG7 also prevented intracellular calcium overload and reduced the expression of proteins involved in the SOCE pathway, thereby preserving calcium homeostasis under oxidative stress conditions. In addition, URG7 attenuated G1 cell cycle arrest and reduced the expression of pro-apoptotic markers, including p53, p21, Bax, and cleaved PARP, while promoting pro-survival signaling pathways such as AKT and ERK1/2. Collectively, these findings identify URG7 as an important regulator of adaptive stress responses and suggest its possible involvement in neuroprotective mechanisms associated with neurodegenerative disorders characterized by oxidative stress.",
"42595562": "ID: 42595562\nTitle: Lysosome-targeted protein degradation platforms for spatiotemporally controlled degradation.\nAbstract: Lysosome-targeted protein degradation (LTPD) represents a therapeutic strategy that degrades membrane and extracellular target proteins through the endolysosomal pathway. LTPD chimeras are molecular degraders that mediate LTPD, but their in vivo performance is limited by poor spatiotemporal control of degradation-existing chimeras have suboptimal pharmacokinetics, tissue selectivity, and endolysosomal trafficking. To overcome these hurdles associated with chimeras, LTPD platforms have emerged. LTPD platforms function as chimera-loaded systems for targeted delivery and controlled release of chimeras, or as platform-based degraders that mediate disease-targeted and on-demand degradation without chimeras. We discuss how LTPD platforms spatiotemporally control degradation and describe their therapeutic applications. In particular, we summarize the design principles of LTPD platforms to address the stringent requirements imposed by the LTPD process. These principles may contribute to the rational design of LTPD platforms.",
"42596071": "ID: 42596071\nTitle: An expanding role for ATG8s and ATG8 E3-like ligases in maintaining membrane integrity.\nAbstract: Endolysosomal membranes are frequently damaged by pathogenic stress associated with aging, infection, and neurodegeneration, and failure to repair such damage leads to inflammation and cell death. Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity."
