The accumulation of amyloid \u03b2 (A\u03b2) deposits and hyperphosphorylated Tau protein (p-Tau) are considered the main hallmarks of AD. A growing body of evidence suggests that the regular intake of flavonoid-rich foods could reduce the risk of developing AD or mitigate its progression. This study explores the potential of quercetin (Q) and epicatechin (EC) as effective molecules against AD-like pathology, using the Caenorhabditis elegans BR5270 strain, which expresses the pro-aggregant F3DK280 fragment of the human Tau protein. The results showed that after exposure to 150\u00a0\u00b5M of EC or Q, worms exhibited increased lifespan, improved chemotaxis, and delayed age-related decline in locomotion. To explore the molecular mechanisms involved, the expression of genes associated with the inhibition of p-Tau proteotoxicity were measured by RT-qPCR. It was found that Q and EC significantly increased the expression levels of autophagy-related genes and of a key gene for de novo synthesis of \u03b1- tubulin. EC and Q delay neurodegeneration in the C. elegans tauopathy model, suggesting their potential to reduce the risk of AD progression."

"abstract_text": "ID: 42399973\nTitle: A putative SGLT-relevant mechanistic perspective on quercetin-3-O-glucoside and rutin in diabetic kidney disease.\nAbstract: Type 2 diabetes mellitus (T2DM) is escalating worldwide and remains difficult to control durably, in part because progressive \u03b2-cell dysfunction undermines many therapies and because long-term management must balance efficacy, safety, and affordability. Recent decades have shown that targeting sodium-glucose cotransporters (SGLTs) especially renal SGLT2 can reduce glucose levels independently of insulin and, crucially, deliver cardio-renal benefits that extend beyond glycaemic control. Yet, despite the clinical success of synthetic \"gliflozins\", gaps remain, adverse events, incomplete inhibition of renal glucose reabsorption, and limited access in some health systems. This review focuses on two quercetin glycosides quercetin-3-O-glucoside (isoquercitrin) and quercetin-3-O-rutinoside (rutin) as potential SGLT-focused modulators. This study employed a narrative mechanistic review approach integrating published experimental evidence, physicochemical structure-activity relationship (SAR) analysis, and exploratory molecular docking to examine potential SGLT-related interactions and complementary glucose-regulatory pathways of Q3G and rutin. We synthesise mechanistic evidence suggesting that Q3G and rutin may modulate SGLT-related pathways through intestinal SGLT1 interaction, regulation of renal SGLT2 expression, and complementary glucose-regulatory mechanisms. However, direct inhibition of human SGLT2 transport activity has not yet been experimentally demonstrated, and current evidence predominantly may indicate indirect pathway modulation rather than gliflozin-like transporter inhibition. Contradictory findings across assay systems are discussed in relation to structure-activity relationships shaped by glycosylation. We further examine pharmacokinetics, tissue exposure plausibility, and translational feasibility, and propose a stepwise development roadmap emphasising transporter-specific assays, quantitative target engagement, and clinically meaningful biomarkers. Q3G and rutin may exhibit putative SGLT-relevant activity within a broader polypharmacological framework; however, direct transporter-specific inhibition and clinically relevant renal exposure remain to be established through future functional and translational studies."

This study aimed to develop an enzyme-responsive, fibrosis-targeted nanotherapeutic system capable of simultaneously delivering siRNA against progranulin (siPGRN) and quercetin (QT) to remodel the fibrotic microenvironment and effectively attenuate renal fibrosis. The TIMP-HDL-Nano@siPGRN&QT nanoparticles prepared in this study exhibit uniform nanoscale size (~\u2009100\u00a0nm), high encapsulation efficiency, excellent stability, and favorable biocompatibility. The MMP9-responsive modification significantly enhanced renal accumulation and fibrotic lesion targeting in vivo. Treatment with TIMP-HDL-Nano@siPGRN&QT markedly alleviated UUO-induced renal injury, apoptosis, and fibrosis, outperforming free drug. Transcriptomic and mechanistic analyses revealed that the therapeutic effects were mediated through disruption of the PGRN-PPAR\u03b1 interaction, restoration of PPAR\u03b1 signaling, and subsequent inhibition of NF-\u03baB-driven inflammatory pathways. Furthermore, the nanoparticles suppressed pro-inflammatory M1 macrophage polarization and promoted M2 polarization in a PPAR\u03b1-dependent manner. This study demonstrates that TIMP-HDL-Nano@siPGRN&QT enables efficient, targeted co-delivery of siRNA and small-molecule therapeutics to fibrotic kidneys. By remodeling the fibrotic immune microenvironment through the PGRN-PPAR\u03b1-NF-\u03baB axis, this nanoplatform provides a potent and mechanistically defined strategy for the treatment of renal fibrosis and offers translational potential for other inflammation-driven fibrotic diseases."

Previous research has demonstrated that quercetin prevents the ferroptosis of oligodendrocyte progenitor cells (OPCs) by inhibiting the Id2/transferrin pathway. Given the ability of quercetin to suppress autophagy in spinal cord injury (SCI), this study aimed to investigate whether quercetin prevents ferroptosis in an autophagy-dependent manner. In erastin-treated OPCs, quercetin significantly upregulated the protein level of ferritin heavy chain (FTH) and markedly reduced its colocalization with LysoTracker, an indicator of lysosome aggregation. Quercetin significantly reduced the ferrous iron levels, the LC3II/LC3I ratio, and the number of LC3 puncta in OPCs, whereas it increased the level of sequestosome 1 (P62) in erastin-treated OPCs. Pretreatment of OPCs with autophagy inhibitor bafilomycin A1 inhibited quercetin-mediated ferritinophagy and ferroptosis, whereas pretreatment with autophagy activator rapamycin reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, as evidenced by reduced protein levels of ferritin heavy chain and p62, as well as increased protein levels of LC3II/LC3I and prostaglandin-endoperoxide synthase 2 (PTGS2). Compared with the erastin and quercetin treated OPCs, increased rerrous iron, lipid peroxidation production, and decreased GSH content, as well as shrunken mitochondria, were observed in OPCs treated with a combination of erastin, quercetin, and rapamycin. In vivo, quercetin significantly downregulated the nuclear receptor coactivator 4 (NCOA4) and PTGS2 protein expression, as well as the LC3II/LC3I ratio. Besides that, quercetin reduced the MDA level and the colocalization of FTH with NCOA4 in spinal cord tissues. Mechanistically, NCOA4 reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, whereas mutation of Y71 to alanine only slightly reversed the above effect. In conclusion, our findings revealed that quercetin inhibits OPCs ferroptosis by blocking NCOA4-mediated ferritinophagy. Quercetin and ferritinophagy may be potential therapeutic agents for SCI."

Quercetin (QR), a natural flavonoid, exerts antioxidant and anti-inflammatory effects by modulating the Nrf2-Keap1 pathway and shows neuroprotective potential in various neurological disorders. In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI, further highlighting the pivotal role of the Nrf2-Keap1 pathway in TBI treatment. However, the poor blood-brain barrier (BBB) permeability and low bioavailability of QR hinder effective brain-targeted delivery and limit its clinical translation. To address these challenges, we developed CAQK peptide-modified, reactive oxygen species (ROS)-responsive nanoparticles (C-PPS/Q), using PPS120 as the core for targeted QR delivery. C-PPS/Q exhibited ROS-triggered QR release, significantly enhanced HT22 cell uptake in\u00a0vitro, reduced ROS levels and apoptosis. In a TBI mouse model, C-PPS/Q specifically accumulated at the lesion site, prolonged the half-life of QR, demonstrated excellent biocompatibility, preserved BBB integrity, attenuated neuroinflammation, inhibited aberrant Nrf2-Keap1 pathway activation, and markedly improved neurological function. Collectively, C-PPS/Q nanoparticles effectively mitigate secondary brain injury after TBI and represent a promising brain-targeted therapeutic strategy for TBI management."

Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established."

Although quercetin, a natural flavonol, possesses potent antifibrotic properties, its clinical utility is severely hindered by poor aqueous solubility and low bioavailability. To address this limitation, we developed a nanoparticle-based drug delivery system using quercetin-loaded human umbilical cord mesenchymal stem cell (hUC-MSC)-derived exosomes (hUC-MSC-exo-Que). Leveraging the innate biocompatibility and targeting capability of exosomes, this strategy aims to improve the pharmacokinetic limitations of quercetin and amplify its therapeutic efficacy. Our results demonstrate that hUC-MSC-exo-Que significantly attenuates liver fibrosis in a carbon tetrachloride-induced mouse model, outperforming free quercetin at the equivalent dose. This enhanced efficacy is attributed to the superior inhibition of hepatic stellate cell activation, as confirmed by in vitro studies. The engineered exosomes exhibited a sustained drug release profile (up to 48 h) and maintained excellent stability for at least 1 week. Integrating network pharmacology with experimental validation, we identify the antifibrotic mechanism involving potent inhibition of the PI3K/Akt signaling pathway, with hUC-MSC-exo-Que achieving markedly greater pathway suppression than free quercetin. By successfully transforming a potent but poorly bioavailable phytochemical into a targeted nanotherapeutic, we present a promising preclinical strategy for liver fibrosis treatment and demonstrate a proof-of-concept platform for hydrophobic drug delivery."

This ethnopharmacological knowledge provides a rich resource for discovering novel anti-inflammatory agents. This review critically evaluates the evidence for the modulation of the Receptor for Advanced Glycation End-products (RAGE) signaling pathway by natural products derived from traditional medicines, aiming to connect this traditional knowledge with modern molecular pharmacology. A comprehensive literature review was performed using the PubMed database. The search focused on keywords such as \"RAGE,\" \"natural products,\" and \"traditional medicine\" to identify studies detailing the mechanistic interactions between natural compounds and the RAGE pathway. Natural products, including polyphenols, terpenoids, and alkaloids, modulate the RAGE axis through several key mechanisms: (1) inhibiting the formation of Advanced Glycation End-products (AGEs); (2) directly blocking the RAGE-ligand interaction; (3) downregulating RAGE expression; and (4) suppressing downstream inflammatory signaling. Compounds like quercetin, ursolic acid, and berberine have demonstrated significant activity in various preclinical models. Natural products represent a profound source of multi-target RAGE modulators, offering a potential therapeutic advantage over synthetic single-target drugs. While challenges in bioavailability and clinical translation remain, the data strongly validates the ethnopharmacological approach. Future progress depends on integrating this traditional wisdom with modern technologies to unlock the full clinical potential of these compounds."

Tanshinone IIA (TIIA), a multi-target bioactive compound derived from Salvia miltiorrhiza, has shown potential in retinal disease treatment. In this study, we investigated the therapeutic effects and underlying mechanisms of TIIA on choroidal neovascularization (CNV) using Vldlr knockout (Vldlr-/-) mice as an nAMD model. TIIA was administered intraperitoneally for 8 weeks, and CNV progression and vascular leakage were evaluated by OCT and FFA, while outer blood-retinal barrier (oBRB) integrity was assessed by immunofluorescence staining. Proteomics analysis combined with western blotting was used to explore the molecular mechanisms. Our results showed that TIIA significantly reduced CNV area and leakage, and restored oBRB integrity by upregulating tight junction proteins ZO-1 and Occludin in the RPE/choroid complex. Mechanistically, TIIA inhibited angiogenesis via suppression of the PLC\u03b3/ERK1/2 signaling pathway. In addition, proteomics analysis revealed enhanced cholesterol efflux, intermediate filament reorganization, and decreased autophagy-related proteins across the retina, RPE/choroid complex, and serum. Collectively, these findings demonstrate that TIIA alleviates nAMD pathology through multi-target mechanisms, including inhibition of angiogenesis, restoration of barrier function, metabolic reprogramming, and modulation of autophagy, highlighting its potential as an alternative therapeutic strategy for nAMD."

The role of aggrephagy-selective autophagy of protein aggregates-in shaping neutrophil heterogeneity and LIHC progression remains poorly understood. We integrated scRNA-seq (183,671 cells), spatial transcriptomics, and bulk datasets (TCGA, GSE39791). Neutrophils (n=12,547) were re-clustered into six subsets, and aggrephagy activity was quantified via UCell scores. Analysis included pseudotime trajectories, cell-cell communication, metabolic scoring, and machine-learning-based feature selection, followed by in vitro functional validation. Aggrephagy activity was significantly elevated in tumor tissues compared with adjacent normal tissues (P < 0.001) and showed strong cell-type specificity, with TANs among the most enriched populations. High-aggrephagy neutrophils exhibited an undifferentiated state, preferential tumor enrichment, and a positive correlation with transcriptomic risk scores. Trajectory analysis positioned these cells at an early differentiation branch and revealed dominant neutrophil-to-stroma signaling through the CCL3-CCR1, SPP1-CD44, and ANXA1-FPR1 axes. Metabolically, high-aggrephagy neutrophils displayed enhanced inflammatory and epithelial mesenchymal-transition programs alongside suppressed oxidative phosphorylation. Integrative network analysis identified a five-gene diagnostic panel (SQSTM1, WDFY3, DOCK4, CD177, LIMK2) with robust performance across bulk cohorts (AUC 0.83-0.91). Among these, LIMK2 marked a highly interactive neutrophil subset and functionally promoted tumor cell proliferation, survival, migration, and invasion in vitro. Aggrephagy is associated with a pro-tumorigenic, metabolically reprogrammed neutrophil state in LIHC. The LIMK2-centered gene panel provides a robust framework for subset identification and nominates candidate targets for future autophagy- and neutrophil-directed studies."

Ferroptosis, a form of cell death triggered by iron-dependent lipid peroxidation, is emerging as a promising new anti-cancer therapeutic strategy. This study aims to identify a key target regulating the ferroptosis process in CRC, screen for small molecule modulators against this target, and elucidate their potential anti-tumor mechanisms. We developed a Drug Discovery Strategy for Targeted Ferroptosis Therapy Based on Bioinformatics-Machine Learning Integration for the Treatment of CRC (DDTF-BMLI-CRC), aiming to identify key ferroptosis regulators. The functional role of this factor in CRC and ferroptosis was validated through knockdown and overexpression techniques, establishing it as a potential therapeutic target. Subsequently, candidate compounds were screened from natural product and FDA databases using a dual-scoring model combining machine learning and deep learning. The direct binding of candidate compounds to target proteins was validated through molecular docking, molecular dynamics simulations, DARTS, CETSA, and SPR techniques. Finally, a series of in vitro and in vivo experiments were conducted to systematically evaluate their anti-tumor effects and potential mechanisms. PANX2 was identified as a key ferroptosis-suppressing gene in CRC. We discovered the natural small molecule dihydroberberine (dhBBR) to be a potent and direct inhibitor of the PANX2 protein. In vitro, dhBBR significantly inhibited the proliferation, migration, and invasion of CRC cells while inducing ferroptosis. In vivo, dhBBR effectively suppressed xenograft tumor growth. Mechanistic studies revealed that dhBBR-induced ferroptotic stress activates autophagy, which in turn promotes GPX4 degradation, thereby amplifying the ferroptotic effect and establishing a ferroptosis-autophagy positive feedback loop. Crucially, PANX2 knockdown largely abolished the additional anti-tumor effect of dhBBR, and dhBBR did not further suppress tumor growth beyond PANX2 knockdown alone. This study demonstrates that PANX2 knockdown suppresses CRC progression by inducing ferroptosis. Furthermore, we identified dhBBR for the first time as a PANX2-targeting small-molecule inhibitor. Our research reveals a novel therapeutic strategy targeting the PANX2-mediated ferroptosis-autophagy axis and provides a highly promising candidate compound for the treatment of CRC."

Hence, employing multiple cell death pathways is an emerging strategy in overcoming treatment resistance in OSCC. We investigate here the effect of heteronemin, a marine sesterterpenoid isolated from sponges, for its anti-cancer potential, hypothesizing that it can induce non-apoptotic cell death pathways to overcome apoptosis-resistant cells and elucidate the underlying mechanisms involved. Our results show that heteronemin significantly kills cancer cells via the induction of the intrinsic apoptotic pathway. It also triggers ferroptosis, down-regulating glutathione peroxidase 4 (GPX4) and upregulating markers of lipid peroxidation such as 4-hydroxynonenal and malondialdehyde. We demonstrate that increasing reactive oxygen species generation plays a central role in triggering these pathways. ensuring the death of the cancer cells despite a compensation attempt via inducing autophagy and modulating Nrf2. Our study is the first to demonstrate the complex but interesting role of heteronemin in killing OSCC cells: inducing apoptosis and switching to ferroptosis as the cells attempt to survive. It also inhibits protective autophagy, leaving OSCC cells incapable of protecting themselves from imminent death. This complex mechanism adds to the existing knowledge on the mechanism of heteronemin as a strong therapeutic compound to treat OSCC cells."

Cytoskeletal damage has been increasingly regarded as a contributing factor in impairing these cellular processes in cancer. Moreover, induction of cell death pathways has been linked to cytoskeletal destabilization. However, the effect of cytoskeletal disruption on cell death mechanisms in ovarian cancer (OC) remains elusive. Several natural compounds have been demonstrated to initiate cytoskeletal destabilization as a mechanism to promote cell death. We have previously shown that one such natural compound derived from marine sources, Malformin A1 (MA1), exhibits high toxicity toward both cisplatin-sensitive (A2780S) and cisplatin-resistant (A2780CP) OC cell lines. Thus, here we evaluate the impact of cytoskeletal destabilization by MA1 treatment on OC cell death by analyzing the expression levels of apoptosis, autophagy, and DNA damage-related genes. Our findings show MA1 treatment significantly downregulated key cytoskeletal proteins while also decreasing the expression of pro-apoptotic markers, suggesting alternative cell death mechanisms. Autophagy-related analyses demonstrated enhanced LC3BI to LC3BII processing, indicating autophagy activation with elevated \u03b3-H2AX levels confirming substantial DNA damage in MA1-treated cells. Notably, MA1 was able to induce pyroptotic cell death, as evidenced by increased caspase-1 expression. Moreover, molecular docking analysis revealed that MA1 displayed the strongest binding affinity for vimentin, GAPDH, and \u03b2-tubulin, providing mechanistic insights into its ability to disrupt cytoskeletal integrity and induce nonapoptotic cell death through multiple pathways, highlighting MA1's potential as a promising therapeutic candidate."

However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation.

Lentivirus infection, alkaline Phosphatase/Alizarin Red S Staining, and RT-qPCR were used to evaluate the osteogenic differentiation of mesenchymal stem cells mediated by SERINC3. MicroCT, H&E, and Masson staining were performed to investigate the bone formation and bone defect repair via Serinc3 knockout (KO) mice and nude mice. RNA sequencing, Co-IP, Western blotting, and Seahorse energy metabolism analysis were performed to elucidate the regulatory mechanism of SERINC3. Here, we identify SERINC3 as a critical regulator of osteogenic differentiation of bone marrow-derived stem cells (BMSCs) and bone regeneration. SERINC3 expression was significantly upregulated during osteogenic differentiation of BMSCs and stem cells from human exfoliated deciduous teeth (SHED). Functional assays revealed that SERINC3 overexpression enhanced osteogenic differentiation, proliferation, and migration of MSCs, while Serinc3-KO impaired these processes and led to osteopenia in mice. In a calvarial defect model, Serinc3-KO mice exhibited 42% less bone volume (BV/TV) and 35% lower bone mineral density (BMD), whereas SERINC3-overexpressing BMSCs significantly improved bone repair. Mechanistically, RNA sequencing and pathway analysis revealed that SERINC3 interacts with IL32 to activate the AMPK-ULK1-autophagy axis, thereby promoting osteogenesis. Additionally, SERINC3 enhanced mitochondrial energy metabolism by upregulating tricarboxylic acid cycle enzymes (ACO1, DLAT, SDHA) and increasing oxygen consumption rates. Rescue experiments confirmed that AMPK inhibition or autophagy blockade abolished SERINC3-mediated osteogenic effects, whereas mitochondrial electron transport chain activators restored osteogenesis in SERINC3-knockdown cells. In summary, this study identifies SERINC3 as a novel regulator of bone formation that orchestrates osteogenesis through IL32-AMPK-autophagy signaling axis and mitochondrial metabolism. These findings highlight SERINC3 as a potential therapeutic target for enhancing bone regeneration and treating skeletal defects."

Mir452 (microRNA 452) is a newly identified, highly sensitive biomarker for septic AKI, but the biological function of Mir452 was unknown. Here we report that Mir452 protects kidney tubular cells in septic AKI by repressing APAF1 (apoptotic peptidase activating factor 1) and associated caspase activation to preserve macroautophagy/autophagy. Using mouse and cell models of septic AKI induced by lipopolysaccharide (LPS), we found that inhibition of Mir452 exacerbated renal dysfunction, tubular apoptosis, and inflammatory responses, whereas Mir452 mimics significantly attenuated kidney injury. Mechanistically, Mir452 was shown to directly bind to the 3' untranslated region (3'UTR) of Apaf1 mRNA, repressing APAF1 expression and thereby inhibiting apoptosome-mediated CASP9 activation. This repression further alleviated caspase-mediated cleavage of autophagy-related proteins like BECN1 and ATG5, leading to the preservation of autophagic flux, which in turn limits inflammasome activation and inflammation. Notably, tubule-specific deletion of Apaf1 recapitulated the protective effects of Mir452, whereas forced Apaf1 expression aggravated injury, an effect reversed by CASP9 knockdown. Furthermore, Mir452 significantly promotes protective autophagy in septic AKI by suppressing the APAF1-CASP9 axis, as evidenced by upregulated ATG5 and BECN1 expression, enhanced LC3-II accumulation and autophagosome-lysosome fusion, along with reduced SQSTM1/p62 levels. Functional rescue experiments demonstrated that Mir452's anti-inflammatory effects depend entirely on activated autophagy, as overexpression fails when autophagy is inhibited. Together, the results unveil the Mir452-APAF1-CASP9-autophagy signaling axis that provides an intrinsic anti-inflammation and anti-apoptosis mechanism, suggesting new therapeutic targets for septic AKI."

In this study, using methylglyoxal (MGO) and glycolaldehyde (GAD) carbonyl metabolites induced protein glycation, leading to misfolding and \u03b2-sheet formation and generation of advanced glycation end products (AGEs). The formed AGEs compromise adipocytes activity. Microscopic and spectroscopic assays were used to examine the impact of MGO and GAD on lipid droplet-associated proteins. The results provide information about how these conditions lead to the appearance of glycated and amyloidogenic proteins formation that hinders metabolism and autophagy in adipocytes. We measured the beneficial effects of metformin (MET), an anti-diabetic drug, on misfolded protein as assessed by thioflavin (ThT) spectroscopy and improved autophagy, determined by LC3 staining. In vitro findings were complemented by in vivo analysis of white adipose tissue (WAT), where lipid droplet-associated \u03b2-amyloid deposits were predominantly linked to adipose triglyceride lipase (ATGL), a lipid droplet protein. Bioinformatics, imaging, biochemical and MS/MS methods affirm ATGL's glycation and its role in \u03b2-sheet secondary structure formation. Our results highlighted the pronounced presence of amyloidogenic proteins in adipocytes treated with carbonyl compounds, potentially reshaping our understanding of adipocyte altered activity in the context of T2D. This in-depth exploration offers novel perspectives on related pathophysiology and underscores the potential of adipocytes as pivotal therapeutic targets, bridging T2D, amyloidosis, protein glycation, and adipocyte malfunction."

Despite advances in surgery, chemotherapy, and targeted therapies, many CRC patients experience limited efficacy, toxicity, or drug resistance. Thus, complementary therapeutic strategies with an improved safety profile are needed. Plant-derived polyphenols emerge as promising candidates for CRC treatment. This review compiles in vitro, in vivo, and clinical evidence on the anticancer activity of polyphenols in CRC. Polyphenols, such as curcumin, resveratrol, quercetin, and flavonoids, are analyzed, with emphasis on molecular mechanisms and chemopreventive potential. In vitro studies consistently demonstrate that these compounds exert anticancer effects by modulating multiple pathways, including PI3K/AKT/mTOR, Wnt/\u03b2-catenin, STAT3, and MAPK/ERK, promoting apoptosis and regulating oxidative stress and inflammation. In vivo studies indicate that curcumin, resveratrol, quercetin, epigallocatechin gallate (EGCG), genistein, luteolin, and fisetin significantly reduce tumor volume, polyp formation, and aberrant crypt foci (ACF). Curcumin has been extensively evaluated in trials, with some studies demonstrating reductions in ACF and improvements in inflammatory markers and quality of life, while others have demonstrated no significant clinical benefit. Preclinical evidence supports the chemopreventive role of polyphenols. Preliminary clinical trials also suggest therapeutic potential for CRC prevention and treatment; however, large-scale, well-controlled clinical trials are required to confirm their safety and efficacy. Plant-derived polyphenols represent promising complementary strategies for CRC prevention and therapy. Future research should prioritize compounds with strong preclinical evidence, standardized formulations, optimized delivery strategies, and rigorously designed randomized trials to facilitate integration into clinical oncology practice."

The results show the darkening of Yaomu color, significant pH changes, and decreases in the contents of total alkaloids and total flavonoids after fermentation(P<0.05). Microbial community analysis reveals that the number of bacterial amplicon sequence variants(ASVs), abundance, and diversity are significantly increased under fermentation with controlled temperature and humidity, with dominant genera including Ligilactobacillus, Levilactobacillus, and Pichia. In contrast, the natural fermentation group is dominated by Levilactobacillus, Lactiplantibacillus, and Pichia. 584 differential components are screened from 3 003 compounds by metabolomic analysis, including 40 alkaloids and 31 flavonoids. The fermentation group with controlled temperature and humidity exhibits the highest number of differential compositions, with the number of 25 alkaloids including hydropeimine and deltaline significantly increasing, 15 alkaloids including neoline significantly decreasing, 18 flavonoids including loquatoside increasing, and 13 flavonoids including kaempferol decreasing. Natural fermentation is conducive to the production of flavonoid compositions such as kaempferol and quercetin, whereas its effect on reducing toxic alkaloids is less pronounced compared to the fermentation with controlled temperature and humidity. Correlation analysis further indicates that alkaloid compositions are positively correlated with bacterial genera such as Lactiplantibacillus, while flavonoid compositions are positively correlated with fungal genera such as Wickerhamomyces. In conclusion, fermentation conditions significantly affect the chemical composition of Yaomu by regulating the microbial community structure. Fermentation with controlled temperature and humidity demonstrates greater advantages in reducing toxic components, providing a scientific basis for optimizing traditional fermentation processes and improving the quality control of TCM."

The accumulation of amyloid \u03b2 (A\u03b2) deposits and hyperphosphorylated Tau protein (p-Tau) are considered the main hallmarks of AD. A growing body of evidence suggests that the regular intake of flavonoid-rich foods could reduce the risk of developing AD or mitigate its progression. This study explores the potential of quercetin (Q) and epicatechin (EC) as effective molecules against AD-like pathology, using the Caenorhabditis elegans BR5270 strain, which expresses the pro-aggregant F3DK280 fragment of the human Tau protein. The results showed that after exposure to 150\u00a0\u00b5M of EC or Q, worms exhibited increased lifespan, improved chemotaxis, and delayed age-related decline in locomotion. To explore the molecular mechanisms involved, the expression of genes associated with the inhibition of p-Tau proteotoxicity were measured by RT-qPCR. It was found that Q and EC significantly increased the expression levels of autophagy-related genes and of a key gene for de novo synthesis of \u03b1- tubulin. EC and Q delay neurodegeneration in the C. elegans tauopathy model, suggesting their potential to reduce the risk of AD progression."

Recent decades have shown that targeting sodium-glucose cotransporters (SGLTs) especially renal SGLT2 can reduce glucose levels independently of insulin and, crucially, deliver cardio-renal benefits that extend beyond glycaemic control. Yet, despite the clinical success of synthetic \"gliflozins\", gaps remain, adverse events, incomplete inhibition of renal glucose reabsorption, and limited access in some health systems. This review focuses on two quercetin glycosides quercetin-3-O-glucoside (isoquercitrin) and quercetin-3-O-rutinoside (rutin) as potential SGLT-focused modulators. This study employed a narrative mechanistic review approach integrating published experimental evidence, physicochemical structure-activity relationship (SAR) analysis, and exploratory molecular docking to examine potential SGLT-related interactions and complementary glucose-regulatory pathways of Q3G and rutin. We synthesise mechanistic evidence suggesting that Q3G and rutin may modulate SGLT-related pathways through intestinal SGLT1 interaction, regulation of renal SGLT2 expression, and complementary glucose-regulatory mechanisms. However, direct inhibition of human SGLT2 transport activity has not yet been experimentally demonstrated, and current evidence predominantly may indicate indirect pathway modulation rather than gliflozin-like transporter inhibition. Contradictory findings across assay systems are discussed in relation to structure-activity relationships shaped by glycosylation. We further examine pharmacokinetics, tissue exposure plausibility, and translational feasibility, and propose a stepwise development roadmap emphasising transporter-specific assays, quantitative target engagement, and clinically meaningful biomarkers. Q3G and rutin may exhibit putative SGLT-relevant activity within a broader polypharmacological framework; however, direct transporter-specific inhibition and clinically relevant renal exposure remain to be established through future functional and translational studies."

Previous research has demonstrated that quercetin prevents the ferroptosis of oligodendrocyte progenitor cells (OPCs) by inhibiting the Id2/transferrin pathway. Given the ability of quercetin to suppress autophagy in spinal cord injury (SCI), this study aimed to investigate whether quercetin prevents ferroptosis in an autophagy-dependent manner. In erastin-treated OPCs, quercetin significantly upregulated the protein level of ferritin heavy chain (FTH) and markedly reduced its colocalization with LysoTracker, an indicator of lysosome aggregation. Quercetin significantly reduced the ferrous iron levels, the LC3II/LC3I ratio, and the number of LC3 puncta in OPCs, whereas it increased the level of sequestosome 1 (P62) in erastin-treated OPCs. Pretreatment of OPCs with autophagy inhibitor bafilomycin A1 inhibited quercetin-mediated ferritinophagy and ferroptosis, whereas pretreatment with autophagy activator rapamycin reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, as evidenced by reduced protein levels of ferritin heavy chain and p62, as well as increased protein levels of LC3II/LC3I and prostaglandin-endoperoxide synthase 2 (PTGS2). Compared with the erastin and quercetin treated OPCs, increased rerrous iron, lipid peroxidation production, and decreased GSH content, as well as shrunken mitochondria, were observed in OPCs treated with a combination of erastin, quercetin, and rapamycin. In vivo, quercetin significantly downregulated the nuclear receptor coactivator 4 (NCOA4) and PTGS2 protein expression, as well as the LC3II/LC3I ratio. Besides that, quercetin reduced the MDA level and the colocalization of FTH with NCOA4 in spinal cord tissues. Mechanistically, NCOA4 reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, whereas mutation of Y71 to alanine only slightly reversed the above effect. In conclusion, our findings revealed that quercetin inhibits OPCs ferroptosis by blocking NCOA4-mediated ferritinophagy. Quercetin and ferritinophagy may be potential therapeutic agents for SCI."

Quercetin (QR), a natural flavonoid, exerts antioxidant and anti-inflammatory effects by modulating the Nrf2-Keap1 pathway and shows neuroprotective potential in various neurological disorders. In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI, further highlighting the pivotal role of the Nrf2-Keap1 pathway in TBI treatment. However, the poor blood-brain barrier (BBB) permeability and low bioavailability of QR hinder effective brain-targeted delivery and limit its clinical translation. To address these challenges, we developed CAQK peptide-modified, reactive oxygen species (ROS)-responsive nanoparticles (C-PPS/Q), using PPS120 as the core for targeted QR delivery. C-PPS/Q exhibited ROS-triggered QR release, significantly enhanced HT22 cell uptake in\u00a0vitro, reduced ROS levels and apoptosis. In a TBI mouse model, C-PPS/Q specifically accumulated at the lesion site, prolonged the half-life of QR, demonstrated excellent biocompatibility, preserved BBB integrity, attenuated neuroinflammation, inhibited aberrant Nrf2-Keap1 pathway activation, and markedly improved neurological function. Collectively, C-PPS/Q nanoparticles effectively mitigate secondary brain injury after TBI and represent a promising brain-targeted therapeutic strategy for TBI management."

Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established."

Although quercetin, a natural flavonol, possesses potent antifibrotic properties, its clinical utility is severely hindered by poor aqueous solubility and low bioavailability. To address this limitation, we developed a nanoparticle-based drug delivery system using quercetin-loaded human umbilical cord mesenchymal stem cell (hUC-MSC)-derived exosomes (hUC-MSC-exo-Que). Leveraging the innate biocompatibility and targeting capability of exosomes, this strategy aims to improve the pharmacokinetic limitations of quercetin and amplify its therapeutic efficacy. Our results demonstrate that hUC-MSC-exo-Que significantly attenuates liver fibrosis in a carbon tetrachloride-induced mouse model, outperforming free quercetin at the equivalent dose. This enhanced efficacy is attributed to the superior inhibition of hepatic stellate cell activation, as confirmed by in vitro studies. The engineered exosomes exhibited a sustained drug release profile (up to 48 h) and maintained excellent stability for at least 1 week. Integrating network pharmacology with experimental validation, we identify the antifibrotic mechanism involving potent inhibition of the PI3K/Akt signaling pathway, with hUC-MSC-exo-Que achieving markedly greater pathway suppression than free quercetin. By successfully transforming a potent but poorly bioavailable phytochemical into a targeted nanotherapeutic, we present a promising preclinical strategy for liver fibrosis treatment and demonstrate a proof-of-concept platform for hydrophobic drug delivery."

This ethnopharmacological knowledge provides a rich resource for discovering novel anti-inflammatory agents. This review critically evaluates the evidence for the modulation of the Receptor for Advanced Glycation End-products (RAGE) signaling pathway by natural products derived from traditional medicines, aiming to connect this traditional knowledge with modern molecular pharmacology. A comprehensive literature review was performed using the PubMed database. The search focused on keywords such as \"RAGE,\" \"natural products,\" and \"traditional medicine\" to identify studies detailing the mechanistic interactions between natural compounds and the RAGE pathway. Natural products, including polyphenols, terpenoids, and alkaloids, modulate the RAGE axis through several key mechanisms: (1) inhibiting the formation of Advanced Glycation End-products (AGEs); (2) directly blocking the RAGE-ligand interaction; (3) downregulating RAGE expression; and (4) suppressing downstream inflammatory signaling. Compounds like quercetin, ursolic acid, and berberine have demonstrated significant activity in various preclinical models. Natural products represent a profound source of multi-target RAGE modulators, offering a potential therapeutic advantage over synthetic single-target drugs. While challenges in bioavailability and clinical translation remain, the data strongly validates the ethnopharmacological approach. Future progress depends on integrating this traditional wisdom with modern technologies to unlock the full clinical potential of these compounds."

Tanshinone IIA (TIIA), a multi-target bioactive compound derived from Salvia miltiorrhiza, has shown potential in retinal disease treatment. In this study, we investigated the therapeutic effects and underlying mechanisms of TIIA on choroidal neovascularization (CNV) using Vldlr knockout (Vldlr-/-) mice as an nAMD model. TIIA was administered intraperitoneally for 8 weeks, and CNV progression and vascular leakage were evaluated by OCT and FFA, while outer blood-retinal barrier (oBRB) integrity was assessed by immunofluorescence staining. Proteomics analysis combined with western blotting was used to explore the molecular mechanisms. Our results showed that TIIA significantly reduced CNV area and leakage, and restored oBRB integrity by upregulating tight junction proteins ZO-1 and Occludin in the RPE/choroid complex. Mechanistically, TIIA inhibited angiogenesis via suppression of the PLC\u03b3/ERK1/2 signaling pathway. In addition, proteomics analysis revealed enhanced cholesterol efflux, intermediate filament reorganization, and decreased autophagy-related proteins across the retina, RPE/choroid complex, and serum.

The role of aggrephagy-selective autophagy of protein aggregates-in shaping neutrophil heterogeneity and LIHC progression remains poorly understood. We integrated scRNA-seq (183,671 cells), spatial transcriptomics, and bulk datasets (TCGA, GSE39791). Neutrophils (n=12,547) were re-clustered into six subsets, and aggrephagy activity was quantified via UCell scores. Analysis included pseudotime trajectories, cell-cell communication, metabolic scoring, and machine-learning-based feature selection, followed by in vitro functional validation. Aggrephagy activity was significantly elevated in tumor tissues compared with adjacent normal tissues (P < 0.001) and showed strong cell-type specificity, with TANs among the most enriched populations. High-aggrephagy neutrophils exhibited an undifferentiated state, preferential tumor enrichment, and a positive correlation with transcriptomic risk scores. Trajectory analysis positioned these cells at an early differentiation branch and revealed dominant neutrophil-to-stroma signaling through the CCL3-CCR1, SPP1-CD44, and ANXA1-FPR1 axes. Metabolically, high-aggrephagy neutrophils displayed enhanced inflammatory and epithelial mesenchymal-transition programs alongside suppressed oxidative phosphorylation. Integrative network analysis identified a five-gene diagnostic panel (SQSTM1, WDFY3, DOCK4, CD177, LIMK2) with robust performance across bulk cohorts (AUC 0.83-0.91). Among these, LIMK2 marked a highly interactive neutrophil subset and functionally promoted tumor cell proliferation, survival, migration, and invasion in vitro. Aggrephagy is associated with a pro-tumorigenic, metabolically reprogrammed neutrophil state in LIHC. The LIMK2-centered gene panel provides a robust framework for subset identification and nominates candidate targets for future autophagy- and neutrophil-directed studies."

Ferroptosis, a form of cell death triggered by iron-dependent lipid peroxidation, is emerging as a promising new anti-cancer therapeutic strategy. This study aims to identify a key target regulating the ferroptosis process in CRC, screen for small molecule modulators against this target, and elucidate their potential anti-tumor mechanisms. We developed a Drug Discovery Strategy for Targeted Ferroptosis Therapy Based on Bioinformatics-Machine Learning Integration for the Treatment of CRC (DDTF-BMLI-CRC), aiming to identify key ferroptosis regulators. The functional role of this factor in CRC and ferroptosis was validated through knockdown and overexpression techniques, establishing it as a potential therapeutic target. Subsequently, candidate compounds were screened from natural product and FDA databases using a dual-scoring model combining machine learning and deep learning. The direct binding of candidate compounds to target proteins was validated through molecular docking, molecular dynamics simulations, DARTS, CETSA, and SPR techniques. Finally, a series of in vitro and in vivo experiments were conducted to systematically evaluate their anti-tumor effects and potential mechanisms. PANX2 was identified as a key ferroptosis-suppressing gene in CRC. We discovered the natural small molecule dihydroberberine (dhBBR) to be a potent and direct inhibitor of the PANX2 protein. In vitro, dhBBR significantly inhibited the proliferation, migration, and invasion of CRC cells while inducing ferroptosis. In vivo, dhBBR effectively suppressed xenograft tumor growth. Mechanistic studies revealed that dhBBR-induced ferroptotic stress activates autophagy, which in turn promotes GPX4 degradation, thereby amplifying the ferroptotic effect and establishing a ferroptosis-autophagy positive feedback loop. Crucially, PANX2 knockdown largely abolished the additional anti-tumor effect of dhBBR, and dhBBR did not further suppress tumor growth beyond PANX2 knockdown alone. This study demonstrates that PANX2 knockdown suppresses CRC progression by inducing ferroptosis. Furthermore, we identified dhBBR for the first time as a PANX2-targeting small-molecule inhibitor. Our research reveals a novel therapeutic strategy targeting the PANX2-mediated ferroptosis-autophagy axis and provides a highly promising candidate compound for the treatment of CRC."

Hence, employing multiple cell death pathways is an emerging strategy in overcoming treatment resistance in OSCC. We investigate here the effect of heteronemin, a marine sesterterpenoid isolated from sponges, for its anti-cancer potential, hypothesizing that it can induce non-apoptotic cell death pathways to overcome apoptosis-resistant cells and elucidate the underlying mechanisms involved. Our results show that heteronemin significantly kills cancer cells via the induction of the intrinsic apoptotic pathway. It also triggers ferroptosis, down-regulating glutathione peroxidase 4 (GPX4) and upregulating markers of lipid peroxidation such as 4-hydroxynonenal and malondialdehyde. We demonstrate that increasing reactive oxygen species generation plays a central role in triggering these pathways. ensuring the death of the cancer cells despite a compensation attempt via inducing autophagy and modulating Nrf2. Our study is the first to demonstrate the complex but interesting role of heteronemin in killing OSCC cells: inducing apoptosis and switching to ferroptosis as the cells attempt to survive. It also inhibits protective autophagy, leaving OSCC cells incapable of protecting themselves from imminent death. This complex mechanism adds to the existing knowledge on the mechanism of heteronemin as a strong therapeutic compound to treat OSCC cells."

Cytoskeletal damage has been increasingly regarded as a contributing factor in impairing these cellular processes in cancer. Moreover, induction of cell death pathways has been linked to cytoskeletal destabilization. However, the effect of cytoskeletal disruption on cell death mechanisms in ovarian cancer (OC) remains elusive. Several natural compounds have been demonstrated to initiate cytoskeletal destabilization as a mechanism to promote cell death. We have previously shown that one such natural compound derived from marine sources, Malformin A1 (MA1), exhibits high toxicity toward both cisplatin-sensitive (A2780S) and cisplatin-resistant (A2780CP) OC cell lines. Thus, here we evaluate the impact of cytoskeletal destabilization by MA1 treatment on OC cell death by analyzing the expression levels of apoptosis, autophagy, and DNA damage-related genes. Our findings show MA1 treatment significantly downregulated key cytoskeletal proteins while also decreasing the expression of pro-apoptotic markers, suggesting alternative cell death mechanisms. Autophagy-related analyses demonstrated enhanced LC3BI to LC3BII processing, indicating autophagy activation with elevated \u03b3-H2AX levels confirming substantial DNA damage in MA1-treated cells. Notably, MA1 was able to induce pyroptotic cell death, as evidenced by increased caspase-1 expression. Moreover, molecular docking analysis revealed that MA1 displayed the strongest binding affinity for vimentin, GAPDH, and \u03b2-tubulin, providing mechanistic insights into its ability to disrupt cytoskeletal integrity and induce nonapoptotic cell death through multiple pathways, highlighting MA1's potential as a promising therapeutic candidate."

We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes."

Astaxanthin (AS), a natural antioxidant, has been shown to exert various biological effects, including anti-aging and anti-inflammatory effects. However, further investigation into its anti-ovarian aging mechanism is warranted. Two-month-old female mice and CTX-induced POF model mice were used. Hematoxylin and eosin staining, immunohistochemical staining, TUNEL assays, Western blotting, and qPCR analyses were employed to evaluate ovarian function and related phenotypes after astaxanthin treatment. Subsequently, network pharmacology analysis was used to elucidated potential targets. Astaxanthin intervention significantly ameliorated estrous cycle disorder in POF mice and restored serum levels of anti-M\u00fcllerian hormone (AMH) and estradiol (E2). Meanwhile, astaxanthin markedly enhanced the ovarian reserve and suppressed CTX-induced apoptosis and autophagy. Mechanistically, astaxanthin was found to modulate the CYP19A1 expression, thereby enhancing ovarian function. This study elucidates the mechanism by which astaxanthin improves ovarian function through the CYP19A1, providing potential molecular targets and therapeutic strategies for the clinical treatment of POF."

"abstract_text": "ID: 42400028\nTitle: SERINC3 promotes osteogenic differentiation of BMSCs via IL-32/AMPK-mediated autophagy and mitochondrial energy metabolism.\nAbstract: SERINC3, a member of the serine incorporator protein family, is known for its roles in viral resistance and tumorigenesis, however, its function in osteogenesis remains unexplored. Lentivirus infection, alkaline Phosphatase/Alizarin Red S Staining, and RT-qPCR were used to evaluate the osteogenic differentiation of mesenchymal stem cells mediated by SERINC3. MicroCT, H&E, and Masson staining were performed to investigate the bone formation and bone defect repair via Serinc3 knockout (KO) mice and nude mice. RNA sequencing, Co-IP, Western blotting, and Seahorse energy metabolism analysis were performed to elucidate the regulatory mechanism of SERINC3. Here, we identify SERINC3 as a critical regulator of osteogenic differentiation of bone marrow-derived stem cells (BMSCs) and bone regeneration. SERINC3 expression was significantly upregulated during osteogenic differentiation of BMSCs and stem cells from human exfoliated deciduous teeth (SHED). Functional assays revealed that SERINC3 overexpression enhanced osteogenic differentiation, proliferation, and migration of MSCs, while Serinc3-KO impaired these processes and led to osteopenia in mice. In a calvarial defect model, Serinc3-KO mice exhibited 42% less bone volume (BV/TV) and 35% lower bone mineral density (BMD), whereas SERINC3-overexpressing BMSCs significantly improved bone repair. Mechanistically, RNA sequencing and pathway analysis revealed that SERINC3 interacts with IL32 to activate the AMPK-ULK1-autophagy axis, thereby promoting osteogenesis. Additionally, SERINC3 enhanced mitochondrial energy metabolism by upregulating tricarboxylic acid cycle enzymes (ACO1, DLAT, SDHA) and increasing oxygen consumption rates. Rescue experiments confirmed that AMPK inhibition or autophagy blockade abolished SERINC3-mediated osteogenic effects, whereas mitochondrial electron transport chain activators restored osteogenesis in SERINC3-knockdown cells. In summary, this study identifies SERINC3 as a novel regulator of bone formation that orchestrates osteogenesis through IL32-AMPK-autophagy signaling axis and mitochondrial metabolism. These findings highlight SERINC3 as a potential therapeutic target for enhancing bone regeneration and treating skeletal defects."

"abstract_text": "ID: 42402931\nTitle: Mir452 protects against septic acute kidney injury by targeting Apaf1 to relieve CASP9-mediated suppression of autophagy.\nAbstract: Septic acute kidney injury (AKI) is associated with high mortality and currently lacks effective therapeutics. Mir452 (microRNA 452) is a newly identified, highly sensitive biomarker for septic AKI, but the biological function of Mir452 was unknown. Here we report that Mir452 protects kidney tubular cells in septic AKI by repressing APAF1 (apoptotic peptidase activating factor 1) and associated caspase activation to preserve macroautophagy/autophagy. Using mouse and cell models of septic AKI induced by lipopolysaccharide (LPS), we found that inhibition of Mir452 exacerbated renal dysfunction, tubular apoptosis, and inflammatory responses, whereas Mir452 mimics significantly attenuated kidney injury. Mechanistically, Mir452 was shown to directly bind to the 3' untranslated region (3'UTR) of Apaf1 mRNA, repressing APAF1 expression and thereby inhibiting apoptosome-mediated CASP9 activation. This repression further alleviated caspase-mediated cleavage of autophagy-related proteins like BECN1 and ATG5, leading to the preservation of autophagic flux, which in turn limits inflammasome activation and inflammation. Notably, tubule-specific deletion of Apaf1 recapitulated the protective effects of Mir452, whereas forced Apaf1 expression aggravated injury, an effect reversed by CASP9 knockdown. Furthermore, Mir452 significantly promotes protective autophagy in septic AKI by suppressing the APAF1-CASP9 axis, as evidenced by upregulated ATG5 and BECN1 expression, enhanced LC3-II accumulation and autophagosome-lysosome fusion, along with reduced SQSTM1/p62 levels. Functional rescue experiments demonstrated that Mir452's anti-inflammatory effects depend entirely on activated autophagy, as overexpression fails when autophagy is inhibited. Together, the results unveil the Mir452-APAF1-CASP9-autophagy signaling axis that provides an intrinsic anti-inflammation and anti-apoptosis mechanism, suggesting new therapeutic targets for septic AKI."

In this study, using methylglyoxal (MGO) and glycolaldehyde (GAD) carbonyl metabolites induced protein glycation, leading to misfolding and \u03b2-sheet formation and generation of advanced glycation end products (AGEs). The formed AGEs compromise adipocytes activity. Microscopic and spectroscopic assays were used to examine the impact of MGO and GAD on lipid droplet-associated proteins. The results provide information about how these conditions lead to the appearance of glycated and amyloidogenic proteins formation that hinders metabolism and autophagy in adipocytes. We measured the beneficial effects of metformin (MET), an anti-diabetic drug, on misfolded protein as assessed by thioflavin (ThT) spectroscopy and improved autophagy, determined by LC3 staining. In vitro findings were complemented by in vivo analysis of white adipose tissue (WAT), where lipid droplet-associated \u03b2-amyloid deposits were predominantly linked to adipose triglyceride lipase (ATGL), a lipid droplet protein. Bioinformatics, imaging, biochemical and MS/MS methods affirm ATGL's glycation and its role in \u03b2-sheet secondary structure formation. Our results highlighted the pronounced presence of amyloidogenic proteins in adipocytes treated with carbonyl compounds, potentially reshaping our understanding of adipocyte altered activity in the context of T2D. This in-depth exploration offers novel perspectives on related pathophysiology and underscores the potential of adipocytes as pivotal therapeutic targets, bridging T2D, amyloidosis, protein glycation, and adipocyte malfunction."

"abstract_text": "ID: 42405384\nTitle: Plant-Derived Polyphenols in the Fight against Colorectal Cancer.\nAbstract: Colorectal cancer (CRC) is the third most common cancer worldwide and a leading cause of cancer-related mortality. Despite advances in surgery, chemotherapy, and targeted therapies, many CRC patients experience limited efficacy, toxicity, or drug resistance. Thus, complementary therapeutic strategies with an improved safety profile are needed. Plant-derived polyphenols emerge as promising candidates for CRC treatment. This review compiles in vitro, in vivo, and clinical evidence on the anticancer activity of polyphenols in CRC. Polyphenols, such as curcumin, resveratrol, quercetin, and flavonoids, are analyzed, with emphasis on molecular mechanisms and chemopreventive potential. In vitro studies consistently demonstrate that these compounds exert anticancer effects by modulating multiple pathways, including PI3K/AKT/mTOR, Wnt/\u03b2-catenin, STAT3, and MAPK/ERK, promoting apoptosis and regulating oxidative stress and inflammation. In vivo studies indicate that curcumin, resveratrol, quercetin, epigallocatechin gallate (EGCG), genistein, luteolin, and fisetin significantly reduce tumor volume, polyp formation, and aberrant crypt foci (ACF). Curcumin has been extensively evaluated in trials, with some studies demonstrating reductions in ACF and improvements in inflammatory markers and quality of life, while others have demonstrated no significant clinical benefit. Preclinical evidence supports the chemopreventive role of polyphenols. Preliminary clinical trials also suggest therapeutic potential for CRC prevention and treatment; however, large-scale, well-controlled clinical trials are required to confirm their safety and efficacy. Plant-derived polyphenols represent promising complementary strategies for CRC prevention and therapy. Future research should prioritize compounds with strong preclinical evidence, standardized formulations, optimized delivery strategies, and rigorously designed randomized trials to facilitate integration into clinical oncology practice."

The results show the darkening of Yaomu color, significant pH changes, and decreases in the contents of total alkaloids and total flavonoids after fermentation(P<0.05). Microbial community analysis reveals that the number of bacterial amplicon sequence variants(ASVs), abundance, and diversity are significantly increased under fermentation with controlled temperature and humidity, with dominant genera including Ligilactobacillus, Levilactobacillus, and Pichia. In contrast, the natural fermentation group is dominated by Levilactobacillus, Lactiplantibacillus, and Pichia. 584 differential components are screened from 3 003 compounds by metabolomic analysis, including 40 alkaloids and 31 flavonoids. The fermentation group with controlled temperature and humidity exhibits the highest number of differential compositions, with the number of 25 alkaloids including hydropeimine and deltaline significantly increasing, 15 alkaloids including neoline significantly decreasing, 18 flavonoids including loquatoside increasing, and 13 flavonoids including kaempferol decreasing. Natural fermentation is conducive to the production of flavonoid compositions such as kaempferol and quercetin, whereas its effect on reducing toxic alkaloids is less pronounced compared to the fermentation with controlled temperature and humidity. Correlation analysis further indicates that alkaloid compositions are positively correlated with bacterial genera such as Lactiplantibacillus, while flavonoid compositions are positively correlated with fungal genera such as Wickerhamomyces. In conclusion, fermentation conditions significantly affect the chemical composition of Yaomu by regulating the microbial community structure. Fermentation with controlled temperature and humidity demonstrates greater advantages in reducing toxic components, providing a scientific basis for optimizing traditional fermentation processes and improving the quality control of TCM."

While Quercetin is extensively cited as an autophagy modulator that promotes the clearance of various toxic aggregates (such as amyloid-beta or alpha-synuclein), DUX4 is not mentioned in the provided literature. Consequently, there is insufficient evidence to support or refute this claim.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific literature was evaluated to determine if Quercetin-induced autophagy modulates DUX4-related proteotoxicity. The claim is currently unsupported by the source material.\n\n### [INTRODUCTION & JUSTIFICATION]\nQuercetin functions as a potent natural product capable of modulating autophagic flux across diverse experimental models, including neurodegenerative diseases and metabolic disorders. Its role in autophagy typically involves the activation of pathways such as AMPK or the inhibition of specific autophagic suppressors. For instance, in models of Alzheimer\u2019s disease and ferritinophagy, Quercetin promotes the clearance of aggregated proteins. However, the specific protein DUX4, which is associated with facioscapulohumeral muscular dystrophy, is absent from the provided evidence set. Therefore, any functional link between Quercetin, autophagy, and DUX4 remains a knowledge gap.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Quercetin acts as a multi-target modulator that enhances autophagy to combat misfolded protein accumulation in neurodegeneration.\n* The interaction between Quercetin and autophagy is highly context-dependent, sometimes acting as an activator and sometimes as an inhibitor (e.g., in ferritinophagy).\n* Nanomicelle-based delivery of Quercetin significantly improves its systemic bioavailability and therapeutic potential compared to free Quercetin.\n* Quercetin suppresses NLRP3 inflammasome activation by modulating upstream oxidative stress and mitochondrial signaling pathways.\n* Autophagy-lysosomal pathway modulation via Quercetin represents a promising strategy for treating protein-aggregation diseases.\n* There is no mention of DUX4 in the entire provided corpus of 50+ research abstracts.\n* Quercetin's therapeutic efficacy is often limited by its poor pharmacokinetic profile, necessitating advanced nanocarrier design.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The accumulation of amyloid \u03b2 (A\u03b2) deposits and hyperphosphorylated Tau protein (p-Tau) are considered the main hallmarks of AD. A growing body of evidence suggests that the regular intake of flavonoid-rich foods could reduce the risk of developing AD or mitigate its progression. This study explores the potential of quercetin (Q) and epicatechin (EC) as effective molecules against AD-like pathology, using the Caenorhabditis elegans BR5270 strain, which expresses the pro-aggregant F3DK280 fragment of the human Tau protein. The results showed that after exposure to 150\u00a0\u00b5M of EC or Q, worms exhibited increased lifespan, improved chemotaxis, and delayed age-related decline in locomotion. To explore the molecular mechanisms involved, the expression of genes associated with the inhibition of p-Tau proteotoxicity were measured by RT-qPCR. It was found that Q and EC significantly increased the expression levels of autophagy-related genes and of a key gene for de novo synthesis of \u03b1- tubulin. EC and Q delay neurodegeneration in the C. elegans tauopathy model, suggesting their potential to reduce the risk of AD progression."

Recent decades have shown that targeting sodium-glucose cotransporters (SGLTs) especially renal SGLT2 can reduce glucose levels independently of insulin and, crucially, deliver cardio-renal benefits that extend beyond glycaemic control. Yet, despite the clinical success of synthetic \"gliflozins\", gaps remain, adverse events, incomplete inhibition of renal glucose reabsorption, and limited access in some health systems. This review focuses on two quercetin glycosides quercetin-3-O-glucoside (isoquercitrin) and quercetin-3-O-rutinoside (rutin) as potential SGLT-focused modulators. This study employed a narrative mechanistic review approach integrating published experimental evidence, physicochemical structure-activity relationship (SAR) analysis, and exploratory molecular docking to examine potential SGLT-related interactions and complementary glucose-regulatory pathways of Q3G and rutin. We synthesise mechanistic evidence suggesting that Q3G and rutin may modulate SGLT-related pathways through intestinal SGLT1 interaction, regulation of renal SGLT2 expression, and complementary glucose-regulatory mechanisms. However, direct inhibition of human SGLT2 transport activity has not yet been experimentally demonstrated, and current evidence predominantly may indicate indirect pathway modulation rather than gliflozin-like transporter inhibition. Contradictory findings across assay systems are discussed in relation to structure-activity relationships shaped by glycosylation. We further examine pharmacokinetics, tissue exposure plausibility, and translational feasibility, and propose a stepwise development roadmap emphasising transporter-specific assays, quantitative target engagement, and clinically meaningful biomarkers. Q3G and rutin may exhibit putative SGLT-relevant activity within a broader polypharmacological framework; however, direct transporter-specific inhibition and clinically relevant renal exposure remain to be established through future functional and translational studies."

"abstract_text": "ID: 39946767\nTitle: Quercetin inhibits oligodendrocytes ferroptosis by blocking NCOA4-mediated ferritinophagy.\nAbstract: Ferritinophagy is a specific type of autophagy that maintains intracellular iron metabolic homeostasis by targeting ferritin, one of the major forms of iron storage in the human body. Previous research has demonstrated that quercetin prevents the ferroptosis of oligodendrocyte progenitor cells (OPCs) by inhibiting the Id2/transferrin pathway. Given the ability of quercetin to suppress autophagy in spinal cord injury (SCI), this study aimed to investigate whether quercetin prevents ferroptosis in an autophagy-dependent manner. In erastin-treated OPCs, quercetin significantly upregulated the protein level of ferritin heavy chain (FTH) and markedly reduced its colocalization with LysoTracker, an indicator of lysosome aggregation. Quercetin significantly reduced the ferrous iron levels, the LC3II/LC3I ratio, and the number of LC3 puncta in OPCs, whereas it increased the level of sequestosome 1 (P62) in erastin-treated OPCs. Pretreatment of OPCs with autophagy inhibitor bafilomycin A1 inhibited quercetin-mediated ferritinophagy and ferroptosis, whereas pretreatment with autophagy activator rapamycin reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, as evidenced by reduced protein levels of ferritin heavy chain and p62, as well as increased protein levels of LC3II/LC3I and prostaglandin-endoperoxide synthase 2 (PTGS2). Compared with the erastin and quercetin treated OPCs, increased rerrous iron, lipid peroxidation production, and decreased GSH content, as well as shrunken mitochondria, were observed in OPCs treated with a combination of erastin, quercetin, and rapamycin. In vivo, quercetin significantly downregulated the nuclear receptor coactivator 4 (NCOA4) and PTGS2 protein expression, as well as the LC3II/LC3I ratio. Besides that, quercetin reduced the MDA level and the colocalization of FTH with NCOA4 in spinal cord tissues. Mechanistically, NCOA4 reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, whereas mutation of Y71 to alanine only slightly reversed the above effect. In conclusion, our findings revealed that quercetin inhibits OPCs ferroptosis by blocking NCOA4-mediated ferritinophagy. Quercetin and ferritinophagy may be potential therapeutic agents for SCI."

Quercetin (QR), a natural flavonoid, exerts antioxidant and anti-inflammatory effects by modulating the Nrf2-Keap1 pathway and shows neuroprotective potential in various neurological disorders. In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI, further highlighting the pivotal role of the Nrf2-Keap1 pathway in TBI treatment. However, the poor blood-brain barrier (BBB) permeability and low bioavailability of QR hinder effective brain-targeted delivery and limit its clinical translation. To address these challenges, we developed CAQK peptide-modified, reactive oxygen species (ROS)-responsive nanoparticles (C-PPS/Q), using PPS120 as the core for targeted QR delivery. C-PPS/Q exhibited ROS-triggered QR release, significantly enhanced HT22 cell uptake in\u00a0vitro, reduced ROS levels and apoptosis. In a TBI mouse model, C-PPS/Q specifically accumulated at the lesion site, prolonged the half-life of QR, demonstrated excellent biocompatibility, preserved BBB integrity, attenuated neuroinflammation, inhibited aberrant Nrf2-Keap1 pathway activation, and markedly improved neurological function. Collectively, C-PPS/Q nanoparticles effectively mitigate secondary brain injury after TBI and represent a promising brain-targeted therapeutic strategy for TBI management."

Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established."

"abstract_text": "ID: 42395946\nTitle: Quercetin Delivered by Mesenchymal Stem Cell-Derived Exosomes Improves Liver Fibrosis via the PI3K/Akt Signaling Pathway.\nAbstract: Liver fibrosis represents a critical stage in the progression of chronic liver diseases to cirrhosis and hepatocellular carcinoma; however, effective therapeutic options remain limited. Although quercetin, a natural flavonol, possesses potent antifibrotic properties, its clinical utility is severely hindered by poor aqueous solubility and low bioavailability. To address this limitation, we developed a nanoparticle-based drug delivery system using quercetin-loaded human umbilical cord mesenchymal stem cell (hUC-MSC)-derived exosomes (hUC-MSC-exo-Que). Leveraging the innate biocompatibility and targeting capability of exosomes, this strategy aims to improve the pharmacokinetic limitations of quercetin and amplify its therapeutic efficacy. Our results demonstrate that hUC-MSC-exo-Que significantly attenuates liver fibrosis in a carbon tetrachloride-induced mouse model, outperforming free quercetin at the equivalent dose. This enhanced efficacy is attributed to the superior inhibition of hepatic stellate cell activation, as confirmed by in vitro studies. The engineered exosomes exhibited a sustained drug release profile (up to 48 h) and maintained excellent stability for at least 1 week. Integrating network pharmacology with experimental validation, we identify the antifibrotic mechanism involving potent inhibition of the PI3K/Akt signaling pathway, with hUC-MSC-exo-Que achieving markedly greater pathway suppression than free quercetin. By successfully transforming a potent but poorly bioavailable phytochemical into a targeted nanotherapeutic, we present a promising preclinical strategy for liver fibrosis treatment and demonstrate a proof-of-concept platform for hydrophobic drug delivery."

This ethnopharmacological knowledge provides a rich resource for discovering novel anti-inflammatory agents. This review critically evaluates the evidence for the modulation of the Receptor for Advanced Glycation End-products (RAGE) signaling pathway by natural products derived from traditional medicines, aiming to connect this traditional knowledge with modern molecular pharmacology. A comprehensive literature review was performed using the PubMed database. The search focused on keywords such as \"RAGE,\" \"natural products,\" and \"traditional medicine\" to identify studies detailing the mechanistic interactions between natural compounds and the RAGE pathway. Natural products, including polyphenols, terpenoids, and alkaloids, modulate the RAGE axis through several key mechanisms: (1) inhibiting the formation of Advanced Glycation End-products (AGEs); (2) directly blocking the RAGE-ligand interaction; (3) downregulating RAGE expression; and (4) suppressing downstream inflammatory signaling. Compounds like quercetin, ursolic acid, and berberine have demonstrated significant activity in various preclinical models. Natural products represent a profound source of multi-target RAGE modulators, offering a potential therapeutic advantage over synthetic single-target drugs. While challenges in bioavailability and clinical translation remain, the data strongly validates the ethnopharmacological approach. Future progress depends on integrating this traditional wisdom with modern technologies to unlock the full clinical potential of these compounds."

Tanshinone IIA (TIIA), a multi-target bioactive compound derived from Salvia miltiorrhiza, has shown potential in retinal disease treatment. In this study, we investigated the therapeutic effects and underlying mechanisms of TIIA on choroidal neovascularization (CNV) using Vldlr knockout (Vldlr-/-) mice as an nAMD model. TIIA was administered intraperitoneally for 8 weeks, and CNV progression and vascular leakage were evaluated by OCT and FFA, while outer blood-retinal barrier (oBRB) integrity was assessed by immunofluorescence staining. Proteomics analysis combined with western blotting was used to explore the molecular mechanisms. Our results showed that TIIA significantly reduced CNV area and leakage, and restored oBRB integrity by upregulating tight junction proteins ZO-1 and Occludin in the RPE/choroid complex. Mechanistically, TIIA inhibited angiogenesis via suppression of the PLC\u03b3/ERK1/2 signaling pathway. In addition, proteomics analysis revealed enhanced cholesterol efflux, intermediate filament reorganization, and decreased autophagy-related proteins across the retina, RPE/choroid complex, and serum. Collectively, these findings demonstrate that TIIA alleviates nAMD pathology through multi-target mechanisms, including inhibition of angiogenesis, restoration of barrier function, metabolic reprogramming, and modulation of autophagy, highlighting its potential as an alternative therapeutic strategy for nAMD."

The role of aggrephagy-selective autophagy of protein aggregates-in shaping neutrophil heterogeneity and LIHC progression remains poorly understood. We integrated scRNA-seq (183,671 cells), spatial transcriptomics, and bulk datasets (TCGA, GSE39791). Neutrophils (n=12,547) were re-clustered into six subsets, and aggrephagy activity was quantified via UCell scores. Analysis included pseudotime trajectories, cell-cell communication, metabolic scoring, and machine-learning-based feature selection, followed by in vitro functional validation. Aggrephagy activity was significantly elevated in tumor tissues compared with adjacent normal tissues (P < 0.001) and showed strong cell-type specificity, with TANs among the most enriched populations. High-aggrephagy neutrophils exhibited an undifferentiated state, preferential tumor enrichment, and a positive correlation with transcriptomic risk scores. Trajectory analysis positioned these cells at an early differentiation branch and revealed dominant neutrophil-to-stroma signaling through the CCL3-CCR1, SPP1-CD44, and ANXA1-FPR1 axes. Metabolically, high-aggrephagy neutrophils displayed enhanced inflammatory and epithelial mesenchymal-transition programs alongside suppressed oxidative phosphorylation. Integrative network analysis identified a five-gene diagnostic panel (SQSTM1, WDFY3, DOCK4, CD177, LIMK2) with robust performance across bulk cohorts (AUC 0.83-0.91). Among these, LIMK2 marked a highly interactive neutrophil subset and functionally promoted tumor cell proliferation, survival, migration, and invasion in vitro. Aggrephagy is associated with a pro-tumorigenic, metabolically reprogrammed neutrophil state in LIHC. The LIMK2-centered gene panel provides a robust framework for subset identification and nominates candidate targets for future autophagy- and neutrophil-directed studies."

Ferroptosis, a form of cell death triggered by iron-dependent lipid peroxidation, is emerging as a promising new anti-cancer therapeutic strategy. This study aims to identify a key target regulating the ferroptosis process in CRC, screen for small molecule modulators against this target, and elucidate their potential anti-tumor mechanisms. We developed a Drug Discovery Strategy for Targeted Ferroptosis Therapy Based on Bioinformatics-Machine Learning Integration for the Treatment of CRC (DDTF-BMLI-CRC), aiming to identify key ferroptosis regulators. The functional role of this factor in CRC and ferroptosis was validated through knockdown and overexpression techniques, establishing it as a potential therapeutic target. Subsequently, candidate compounds were screened from natural product and FDA databases using a dual-scoring model combining machine learning and deep learning. The direct binding of candidate compounds to target proteins was validated through molecular docking, molecular dynamics simulations, DARTS, CETSA, and SPR techniques. Finally, a series of in vitro and in vivo experiments were conducted to systematically evaluate their anti-tumor effects and potential mechanisms. PANX2 was identified as a key ferroptosis-suppressing gene in CRC. We discovered the natural small molecule dihydroberberine (dhBBR) to be a potent and direct inhibitor of the PANX2 protein. In vitro, dhBBR significantly inhibited the proliferation, migration, and invasion of CRC cells while inducing ferroptosis. In vivo, dhBBR effectively suppressed xenograft tumor growth. Mechanistic studies revealed that dhBBR-induced ferroptotic stress activates autophagy, which in turn promotes GPX4 degradation, thereby amplifying the ferroptotic effect and establishing a ferroptosis-autophagy positive feedback loop. Crucially, PANX2 knockdown largely abolished the additional anti-tumor effect of dhBBR, and dhBBR did not further suppress tumor growth beyond PANX2 knockdown alone. This study demonstrates that PANX2 knockdown suppresses CRC progression by inducing ferroptosis. Furthermore, we identified dhBBR for the first time as a PANX2-targeting small-molecule inhibitor. Our research reveals a novel therapeutic strategy targeting the PANX2-mediated ferroptosis-autophagy axis and provides a highly promising candidate compound for the treatment of CRC."

Hence, employing multiple cell death pathways is an emerging strategy in overcoming treatment resistance in OSCC. We investigate here the effect of heteronemin, a marine sesterterpenoid isolated from sponges, for its anti-cancer potential, hypothesizing that it can induce non-apoptotic cell death pathways to overcome apoptosis-resistant cells and elucidate the underlying mechanisms involved. Our results show that heteronemin significantly kills cancer cells via the induction of the intrinsic apoptotic pathway. It also triggers ferroptosis, down-regulating glutathione peroxidase 4 (GPX4) and upregulating markers of lipid peroxidation such as 4-hydroxynonenal and malondialdehyde. We demonstrate that increasing reactive oxygen species generation plays a central role in triggering these pathways. ensuring the death of the cancer cells despite a compensation attempt via inducing autophagy and modulating Nrf2. Our study is the first to demonstrate the complex but interesting role of heteronemin in killing OSCC cells: inducing apoptosis and switching to ferroptosis as the cells attempt to survive. It also inhibits protective autophagy, leaving OSCC cells incapable of protecting themselves from imminent death. This complex mechanism adds to the existing knowledge on the mechanism of heteronemin as a strong therapeutic compound to treat OSCC cells."

Cytoskeletal damage has been increasingly regarded as a contributing factor in impairing these cellular processes in cancer. Moreover, induction of cell death pathways has been linked to cytoskeletal destabilization. However, the effect of cytoskeletal disruption on cell death mechanisms in ovarian cancer (OC) remains elusive. Several natural compounds have been demonstrated to initiate cytoskeletal destabilization as a mechanism to promote cell death. We have previously shown that one such natural compound derived from marine sources, Malformin A1 (MA1), exhibits high toxicity toward both cisplatin-sensitive (A2780S) and cisplatin-resistant (A2780CP) OC cell lines. Thus, here we evaluate the impact of cytoskeletal destabilization by MA1 treatment on OC cell death by analyzing the expression levels of apoptosis, autophagy, and DNA damage-related genes. Our findings show MA1 treatment significantly downregulated key cytoskeletal proteins while also decreasing the expression of pro-apoptotic markers, suggesting alternative cell death mechanisms. Autophagy-related analyses demonstrated enhanced LC3BI to LC3BII processing, indicating autophagy activation with elevated \u03b3-H2AX levels confirming substantial DNA damage in MA1-treated cells. Notably, MA1 was able to induce pyroptotic cell death, as evidenced by increased caspase-1 expression. Moreover, molecular docking analysis revealed that MA1 displayed the strongest binding affinity for vimentin, GAPDH, and \u03b2-tubulin, providing mechanistic insights into its ability to disrupt cytoskeletal integrity and induce nonapoptotic cell death through multiple pathways, highlighting MA1's potential as a promising therapeutic candidate."

However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes."

Astaxanthin (AS), a natural antioxidant, has been shown to exert various biological effects, including anti-aging and anti-inflammatory effects. However, further investigation into its anti-ovarian aging mechanism is warranted. Two-month-old female mice and CTX-induced POF model mice were used. Hematoxylin and eosin staining, immunohistochemical staining, TUNEL assays, Western blotting, and qPCR analyses were employed to evaluate ovarian function and related phenotypes after astaxanthin treatment.

Lentivirus infection, alkaline Phosphatase/Alizarin Red S Staining, and RT-qPCR were used to evaluate the osteogenic differentiation of mesenchymal stem cells mediated by SERINC3. MicroCT, H&E, and Masson staining were performed to investigate the bone formation and bone defect repair via Serinc3 knockout (KO) mice and nude mice. RNA sequencing, Co-IP, Western blotting, and Seahorse energy metabolism analysis were performed to elucidate the regulatory mechanism of SERINC3. Here, we identify SERINC3 as a critical regulator of osteogenic differentiation of bone marrow-derived stem cells (BMSCs) and bone regeneration. SERINC3 expression was significantly upregulated during osteogenic differentiation of BMSCs and stem cells from human exfoliated deciduous teeth (SHED). Functional assays revealed that SERINC3 overexpression enhanced osteogenic differentiation, proliferation, and migration of MSCs, while Serinc3-KO impaired these processes and led to osteopenia in mice. In a calvarial defect model, Serinc3-KO mice exhibited 42% less bone volume (BV/TV) and 35% lower bone mineral density (BMD), whereas SERINC3-overexpressing BMSCs significantly improved bone repair. Mechanistically, RNA sequencing and pathway analysis revealed that SERINC3 interacts with IL32 to activate the AMPK-ULK1-autophagy axis, thereby promoting osteogenesis. Additionally, SERINC3 enhanced mitochondrial energy metabolism by upregulating tricarboxylic acid cycle enzymes (ACO1, DLAT, SDHA) and increasing oxygen consumption rates. Rescue experiments confirmed that AMPK inhibition or autophagy blockade abolished SERINC3-mediated osteogenic effects, whereas mitochondrial electron transport chain activators restored osteogenesis in SERINC3-knockdown cells. In summary, this study identifies SERINC3 as a novel regulator of bone formation that orchestrates osteogenesis through IL32-AMPK-autophagy signaling axis and mitochondrial metabolism. These findings highlight SERINC3 as a potential therapeutic target for enhancing bone regeneration and treating skeletal defects."

Mir452 (microRNA 452) is a newly identified, highly sensitive biomarker for septic AKI, but the biological function of Mir452 was unknown. Here we report that Mir452 protects kidney tubular cells in septic AKI by repressing APAF1 (apoptotic peptidase activating factor 1) and associated caspase activation to preserve macroautophagy/autophagy. Using mouse and cell models of septic AKI induced by lipopolysaccharide (LPS), we found that inhibition of Mir452 exacerbated renal dysfunction, tubular apoptosis, and inflammatory responses, whereas Mir452 mimics significantly attenuated kidney injury. Mechanistically, Mir452 was shown to directly bind to the 3' untranslated region (3'UTR) of Apaf1 mRNA, repressing APAF1 expression and thereby inhibiting apoptosome-mediated CASP9 activation. This repression further alleviated caspase-mediated cleavage of autophagy-related proteins like BECN1 and ATG5, leading to the preservation of autophagic flux, which in turn limits inflammasome activation and inflammation. Notably, tubule-specific deletion of Apaf1 recapitulated the protective effects of Mir452, whereas forced Apaf1 expression aggravated injury, an effect reversed by CASP9 knockdown. Furthermore, Mir452 significantly promotes protective autophagy in septic AKI by suppressing the APAF1-CASP9 axis, as evidenced by upregulated ATG5 and BECN1 expression, enhanced LC3-II accumulation and autophagosome-lysosome fusion, along with reduced SQSTM1/p62 levels. Functional rescue experiments demonstrated that Mir452's anti-inflammatory effects depend entirely on activated autophagy, as overexpression fails when autophagy is inhibited. Together, the results unveil the Mir452-APAF1-CASP9-autophagy signaling axis that provides an intrinsic anti-inflammation and anti-apoptosis mechanism, suggesting new therapeutic targets for septic AKI."

In this study, using methylglyoxal (MGO) and glycolaldehyde (GAD) carbonyl metabolites induced protein glycation, leading to misfolding and \u03b2-sheet formation and generation of advanced glycation end products (AGEs). The formed AGEs compromise adipocytes activity. Microscopic and spectroscopic assays were used to examine the impact of MGO and GAD on lipid droplet-associated proteins. The results provide information about how these conditions lead to the appearance of glycated and amyloidogenic proteins formation that hinders metabolism and autophagy in adipocytes. We measured the beneficial effects of metformin (MET), an anti-diabetic drug, on misfolded protein as assessed by thioflavin (ThT) spectroscopy and improved autophagy, determined by LC3 staining. In vitro findings were complemented by in vivo analysis of white adipose tissue (WAT), where lipid droplet-associated \u03b2-amyloid deposits were predominantly linked to adipose triglyceride lipase (ATGL), a lipid droplet protein.

Thus, complementary therapeutic strategies with an improved safety profile are needed. Plant-derived polyphenols emerge as promising candidates for CRC treatment. This review compiles in vitro, in vivo, and clinical evidence on the anticancer activity of polyphenols in CRC. Polyphenols, such as curcumin, resveratrol, quercetin, and flavonoids, are analyzed, with emphasis on molecular mechanisms and chemopreventive potential. In vitro studies consistently demonstrate that these compounds exert anticancer effects by modulating multiple pathways, including PI3K/AKT/mTOR, Wnt/\u03b2-catenin, STAT3, and MAPK/ERK, promoting apoptosis and regulating oxidative stress and inflammation. In vivo studies indicate that curcumin, resveratrol, quercetin, epigallocatechin gallate (EGCG), genistein, luteolin, and fisetin significantly reduce tumor volume, polyp formation, and aberrant crypt foci (ACF). Curcumin has been extensively evaluated in trials, with some studies demonstrating reductions in ACF and improvements in inflammatory markers and quality of life, while others have demonstrated no significant clinical benefit. Preclinical evidence supports the chemopreventive role of polyphenols. Preliminary clinical trials also suggest therapeutic potential for CRC prevention and treatment; however, large-scale, well-controlled clinical trials are required to confirm their safety and efficacy. Plant-derived polyphenols represent promising complementary strategies for CRC prevention and therapy. Future research should prioritize compounds with strong preclinical evidence, standardized formulations, optimized delivery strategies, and rigorously designed randomized trials to facilitate integration into clinical oncology practice."

The results show the darkening of Yaomu color, significant pH changes, and decreases in the contents of total alkaloids and total flavonoids after fermentation(P<0.05). Microbial community analysis reveals that the number of bacterial amplicon sequence variants(ASVs), abundance, and diversity are significantly increased under fermentation with controlled temperature and humidity, with dominant genera including Ligilactobacillus, Levilactobacillus, and Pichia. In contrast, the natural fermentation group is dominated by Levilactobacillus, Lactiplantibacillus, and Pichia. 584 differential components are screened from 3 003 compounds by metabolomic analysis, including 40 alkaloids and 31 flavonoids. The fermentation group with controlled temperature and humidity exhibits the highest number of differential compositions, with the number of 25 alkaloids including hydropeimine and deltaline significantly increasing, 15 alkaloids including neoline significantly decreasing, 18 flavonoids including loquatoside increasing, and 13 flavonoids including kaempferol decreasing. Natural fermentation is conducive to the production of flavonoid compositions such as kaempferol and quercetin, whereas its effect on reducing toxic alkaloids is less pronounced compared to the fermentation with controlled temperature and humidity. Correlation analysis further indicates that alkaloid compositions are positively correlated with bacterial genera such as Lactiplantibacillus, while flavonoid compositions are positively correlated with fungal genera such as Wickerhamomyces. In conclusion, fermentation conditions significantly affect the chemical composition of Yaomu by regulating the microbial community structure. Fermentation with controlled temperature and humidity demonstrates greater advantages in reducing toxic components, providing a scientific basis for optimizing traditional fermentation processes and improving the quality control of TCM."

While Quercetin is extensively cited as an autophagy modulator that promotes the clearance of various toxic aggregates (such as amyloid-beta or alpha-synuclein), DUX4 is not mentioned in the provided literature. Consequently, there is insufficient evidence to support or refute this claim.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific literature was evaluated to determine if Quercetin-induced autophagy modulates DUX4-related proteotoxicity. The claim is currently unsupported by the source material.\n\n### [INTRODUCTION & JUSTIFICATION]\nQuercetin functions as a potent natural product capable of modulating autophagic flux across diverse experimental models, including neurodegenerative diseases and metabolic disorders. Its role in autophagy typically involves the activation of pathways such as AMPK or the inhibition of specific autophagic suppressors. For instance, in models of Alzheimer\u2019s disease and ferritinophagy, Quercetin promotes the clearance of aggregated proteins. However, the specific protein DUX4, which is associated with facioscapulohumeral muscular dystrophy, is absent from the provided evidence set. Therefore, any functional link between Quercetin, autophagy, and DUX4 remains a knowledge gap.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Quercetin acts as a multi-target modulator that enhances autophagy to combat misfolded protein accumulation in neurodegeneration.\n* The interaction between Quercetin and autophagy is highly context-dependent, sometimes acting as an activator and sometimes as an inhibitor (e.g., in ferritinophagy).\n* Nanomicelle-based delivery of Quercetin significantly improves its systemic bioavailability and therapeutic potential compared to free Quercetin.\n* Quercetin suppresses NLRP3 inflammasome activation by modulating upstream oxidative stress and mitochondrial signaling pathways.\n* Autophagy-lysosomal pathway modulation via Quercetin represents a promising strategy for treating protein-aggregation diseases.\n* There is no mention of DUX4 in the entire provided corpus of 50+ research abstracts.\n* Quercetin's therapeutic efficacy is often limited by its poor pharmacokinetic profile, necessitating advanced nanocarrier design.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Although excessive stress is known to inactivate these mechanisms and thereby induce mitophagy in cancer cells, the detailed molecular mechanisms coordinating these mitochondrial quality control processes remain unclear. Herein, we identify CLPX, a mitochondrial protease subunit, as an iron-sulfur protein, which requires a [4Fe-4S] cluster to bind with CLPP to exert proteolysis function. Iron chelation impairs the assembly of the [4Fe-4S] cluster onto CLPX, thereby disrupting mitochondrial proteostasis maintenance and inducing mitophagy. Furthermore, cysteine deprivation caused by excessive reactive oxygen species accumulation hinders iron-sulfur cluster biosynthesis, thereby undermining CLPX function and inducing mitophagy. Our research elucidates an iron-sulfur cluster-dependent mechanism sustaining mitochondrial proteostasis.\n\nID: 42173608\nTitle: Hybrid dextran/fibronectin nanogels for brain-targeted mitophagy inducer delivery to alleviate neuroinflammation and neuronal loss of Parkinson's disease.\nAbstract: Parkinson's disease (PD) is characterized by progressive dopaminergic neuron loss, chronic neuroinflammation, and \u03b1-synuclein aggregation. Blood-brain barrier (BBB)-penetrable, dual-target nanomedicines for microglial inflammation and neuronal degeneration remain challenging. In this study, we fabricated a brain-targeted, pH- and reactive oxygen species (ROS)-responsive nanogel (NG) platform using dextran (Dex) as the main polysaccharide backbone, crosslinked with inflammation-targeting fibronectin (FN), and loaded with neuroprotective quercetin (Que). Dex-FN/Que NGs exhibited a uniform spherical morphology with an average diameter of 187\u00a0nm, favorable colloidal stability, and stimuli-triggered drug release behavior. Abundant hydroxyl groups on Dex enabled efficient BBB penetration, while FN mediated integrin-dependent internalization in microglia and neurons. These NGs suppressed the nuclear factor-kappa B (NF-\u03baB) signaling pathway, scavenged ROS, promoted favorable microglial polarization, and balanced oxidative stress. Meanwhile, mitophagy flux activated by the NGs in neurons exerted strong neuroprotection effect. In a mouse model of PD, Dex-FN/Que NGs effectively crossed the BBB and accumulated in injured brain regions, significantly protecting dopaminergic neurons, improving motor function, and relieving depressive-like behaviors. Therapeutic benefits arose from normalized microglial polarization, reduced oxidative stress, and inhibited neuronal ferroptosis. This Dex-based stimuli-responsive nanoplatform provides a promising brain-targeted strategy for the treatment of PD and other neurological disorders.\n\nID: 42136278\nTitle: Therapeutic Insights into Natural Products for Modulating Neurodegenerative Disease Pathways.\nAbstract: Neurodegenerative Disorders (NDs), such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and Amyotrophic Lateral Sclerosis (ALS), are chronic and progressive conditions marked by the gradual loss of neuronal structure and function. These disorders lead to cognitive, motor, and sensory decline, significantly reducing quality of life and posing a major global health burden due to rising healthcare costs and the absence of curative therapies. This review aims to comprehensively explore the therapeutic potential of natural products in targeting cellular and molecular mechanisms underlying NDs, highlighting their neuroprotective roles and potential for disease modification. A comprehensive literature review was conducted using databases including PubMed, Scopus, Web of Science, and Google Scholar. Peer-reviewed articles, clinical trials, and experimental studies were analyzed to evaluate the therapeutic potential of natural products and their bioactive compounds in the management of NDs. ND pathogenesis involves oxidative stress, neuroinflammation, mitochondrial dysfunction, and abnormal protein aggregation, ultimately leading to neuronal death. Current therapies largely provide symptomatic relief without altering disease progression. Natural products from plants, fungi, and marine sources demonstrate strong neuroprotective potential through multitargeted mechanisms. Bioactive compounds such as flavonoids, alkaloids, terpenoids, and polyphenols exhibit antioxidant, anti-inflammatory, anti-apoptotic, and neuroprotective activities. Key molecules, including curcumin, resveratrol, luteolin, quercetin, and catechins, modulate signaling pathways such as NF-\u03baB, MAPK, PI3K/AKT, Nrf2, apoptosis, and autophagy, thereby reducing amyloid-beta aggregation, protecting dopaminergic neurons, improving mitochondrial function, and enhancing cognition in preclinical and clinical studies. Natural products represent promising candidates for disease modification in NDs due to their multi-pathway actions and relatively low toxicity. However, major limitations, such as poor bioavailability, pharmacokinetic variability, and the lack of standardized formulations, hinder clinical translation. Innovative strategies, including advanced drug-delivery systems, structural modifications, and synergistic formulations, are needed to overcome these barriers. Natural products hold significant therapeutic potential in managing neurodegenerative diseases by targeting multiple pathological mechanisms. Their integration into ND treatment could provide safer and more effective alternatives, but further well-designed clinical trials are essential to establish their efficacy and facilitate clinical application.\n\nID: 41802625\nTitle: The role of autophagy in mycotoxin-induced toxicity: A review.\nAbstract: Mycotoxins are widespread toxic secondary metabolites produced by fungi, posing substantial health risks to humans and animals. Recent studies have highlighted the crucial role of autophagy in mediating mycotoxin-induced toxicity. As a highly conserved intracellular degradation pathway, autophagy maintains cellular homeostasis by selectively removing damaged organelles and misfolded protein aggregates. However, its function in the context of mycotoxin exposure is dualistic: it can act either as a protective mechanism or contribute to detrimental cellular outcomes. This review focuses on recent advances in understanding the role of autophagy in mycotoxin-induced toxicity and discusses potential intervention strategies by targeting the autophagy pathway.\n\nID: 41564984\nTitle: Total flavonoids isolated from Fructus Mume (Prunus mume Sieb. et Zucc.) mitigate Parkinson's disease progression by promoting neuronal mitophagy via activation of the CaMKK\u03b2/AMPK signaling pathway.\nAbstract: Fructus Mume (FM) is derived from the nearly ripe fruit of Prunus mume Sieb. et Zucc., and widely used as a traditional medicine in Asian countries. FM has the effect of calming Liver to stop endogenous Wind, and has been used for thousands of years in the treatment of Parkinson's disease (PD), as recorded in ancient formulas such as Wumei Pills. However, the specific mechanism by which it treats PD remains larger unclear. The aim of this study was to investigate the effects and mechanisms by which the active ingredients of FM (Fructus Mume flavonoids, FMF) mitigate the progression of PD. We isolated FMF from FM and explored its chemical composition and active compound content. In vivo and in vitro PD models were employed to investigate the alleviative effects of FMF on PD and its underlying mechanisms. We identified 193 compounds and quantified 154 flavonoid compounds in the FMF. Six compounds were present at concentrations exceeding 100\u00a0\u03bcg/g, namely Isorhamnetin (1287.0639\u00a0\u03bcg/g), Narcissin (764.9639\u00a0\u03bcg/g), Nicotiflorin (613.8568\u00a0\u03bcg/g), Quercetin (435.5215\u00a0\u03bcg/g), Nepitrin (295.4833\u00a0\u03bcg/g), and Kaempferol (241.9767\u00a0\u03bcg/g). Moreover, FMF alleviated behavioral deficits in PD rats. FMF also inhibited the loss of neurons and the formation of \u03b1-synuclein aggregates, and promoted the expression of tyrosine hydroxylase in the substantia nigra pars compacta in PD rats. In vivo and in vitro PD models demonstrated that autophagy inhibition significantly abolished the neuroprotective effects of FMF. Mechanically, FMF could enhance mitophagy to attenuate the mitochondrial dysfunction by activating the Ca2+/calmodulin-dependent protein kinase kinase \u03b2 (CaMKK\u03b2)/AMP-activated protein kinase (AMPK) signaling pathway. FMF promotes neuronal mitophagy to exert the neuroprotective effects by activating the CaMKK\u03b2/AMPK signaling pathway. These findings provide a theoretical foundation for the application of FM in the treatment of PD and promote the clinical application of FM.\n\nID: 41450115\nTitle: Proteotoxic stress triggers TFEB- and TFE3-mediated autophagy and lysosomal biogenesis via non-canonical MTORC1 inactivation.\nAbstract: Proteotoxic stress, arising from conditions that cause misfolded protein accumulation, is closely linked to the pathogenesis of multiple diseases. Macroautophagy/autophagy activation is considered a compensatory mechanism to maintain protein homeostasis, but the underlying regulatory mechanisms remain incompletely understood. Here, we show that proteotoxic stress induced by proteasome inhibition, puromycin treatment, or polyglutamine-expanded HTT (huntingtin) expression promotes nuclear accumulation of TFEB and TFE3, key regulators of lysosomal biogenesis and autophagy. Mechanistically, TFEB activation under proteotoxic stress occurs independently of canonical MTORC1 inactivation mediated by TSC2 or ATF4. Instead, it involves non-canonical inhibition of MTORC1 via RRAG GTPases. Proteotoxic stress disrupts the RRAGC-TFEB interaction, preventing TFEB recruitment to lysosomes and subsequent MTORC1 phosphorylation. An activated RRAGC mutant rescues impaired lysosomal localization and nuclear accumulation of TFEB, while co-overexpression of FLCN and FNIP2, a GAP for RRAGC, partially restores stress-induced TFEB dephosphorylation. In addition, proteasome inhibition activates non-canonical autophagy. Deletion of ATG16L1 or ATG5, which known blocks Atg8-family protein lipidation and sequesters the FLCN-FNIP2 complex, partially abolishes proteotoxic stress-induced TFEB dephosphorylation and nuclear accumulation. Together, these findings demonstrate that proteotoxic stress triggers both non-canonical autophagy and TFEB-mediated canonical autophagy, with Atg8-family protein lipidation contributing to TFEB activation. Our results provide novel insights into how proteotoxic stress engages non-canonical MTORC1 inhibition and TFEB activation, thereby enhancing understanding of cellular adaptation to proteotoxic stress.Abbreviations: ALP, autophagy-lysosomal pathway; ATF4, activating transcription factor 4; Baf A1, bafilomycin A1; CHX, cycloheximide; BTZ, bortezomib; CFZ, carfilzomib; CQ, chloroquine; CTSB, cathepsin B; CTSD, cathepsin D; DQ-BSA, dequenched-bovine serum albumin; EIF4EBP1/4EBP1, eukaryotic translation initiation factor 4E binding protein 1; ER, endoplasmic reticulum; MAP1LC3B/LC3B, microtubule associated protein 1 light chain 3 beta; MG132, carbobenzoxy-Leu-Leu-leucinal; MTORC1, mechanistic target of rapamycin kinase complex 1; RPS6KB1/p70, ribosomal protein S6 kinase B1; RRAG, Ras related GTP binding; SQSTM1/p62, sequestosome 1; TFE3, transcription factor E3; TFEB, transcription factor EB; TSC2, TSC complex subunit 2; tfLC3, tandem fluorescent LC3; UPS, ubiquitin-proteasome system.\n\nID: 41351658\nTitle: Senolytics as Modulators of Critical Signaling Pathways: a Promising Strategy to Combat Brain Aging and Neurodegenerative Disorders.\nAbstract: Aging of the brain, an intricate process, is a significant risk factor for neurodegenerative disorders (NDDs), such as Alzheimer's disease and Parkinson's disease. Senescent cell accumulation is an important hallmark of brain aging. These cells resist apoptotic cell death, produce proinflammatory cytokines, increase oxidative stress, and store toxic proteins that exacerbate neurodegeneration. These senescent cells cause neuroinflammation and dysfunction of the neuronal microenvironment by transmitting senescent phenotypes to neighboring healthy cells. Senolytics have become a viable treatment option to reduce the effects of brain aging since they specifically target and destroy senescent cells. Numerous senolytic compounds, such as dasatinib, fisetin, and quercetin, effectively eliminate senescent cells and reduce the accumulation of harmful substances, including misfolded toxic protein aggregates and reactive oxygen species, thereby helping to maintain tissue homeostasis. These medications aid in reducing oxidative stress and inflammation, two significant factors in brain aging and NDDs, by encouraging the removal of senescent cells. The key molecules involved in this process are mTOR, Nrf2-Keap1, AMPK, and Sirtuin 1 (SIRT1). The modulation of the mTOR and AMPK pathways affects autophagy and cellular metabolism, facilitating the elimination of harmful accumulations and damaged cell organelles. In addition, cellular repair and improved antioxidant defense are encouraged by the activation of the SIRT1 and Nrf2 pathways. The combination of senolytic therapy with these signaling pathways provides a novel approach to attack the cellular and molecular foundations of brain aging and neurodegenerative disorders.\n\nID: 41314255\nTitle: Neurodegenerative disease and autophagy in iPSC-based models.\nAbstract: Neurodegenerative diseases are characterized by the gradual deterioration of specific neuronal populations, ultimately resulting in motor, cognitive, or behavioral impairments. Despite the worldwide increase in disease incidence, effective therapies remain unavailable. A common pathological hallmark of neurodegenerative diseases is the accumulation of misfolded protein aggregates. Accordingly, numerous studies and therapeutic strategies have focused on targeting these toxic aggregates and protein quality control via autophagy, a vital cellular recycling mechanism. Autophagy dysregulation has been implicated in the pathogenesis of several neurodegenerative diseases. Induced pluripotent stem cell (iPSC) technology has emerged as a powerful platform for modeling neurodegenerative diseases, and iPSC-based models provide human-relevant systems for studying autophagic dysfunction in vitro. In this review, we discuss the key findings of recent studies investigating autophagy in iPSC-based models of neurodegenerative diseases, including Alzheimer's disease, amyotrophic lateral sclerosis, frontotemporal dementia, and other diseases.\n\nID: 41306019\nTitle: The Role of Hsp72 in Handing Misfolded Proteins Metabolism in Heat-Stressed Cells: Mechanisms and Hypotheses.\nAbstract: The accumulation of misfolded proteins within cells, often induced by stress, is a major contributor to cellular dysfunction. Heat shock proteins, which serve as critical chaperone molecules in response to stress-related damage, are essential for maintaining protein homeostasis within cells. In this family of proteins, Heat Shock Protein 72 (Hsp72) stands out for its acute responsiveness to thermal stress. It can swiftly be produced in reaction to the surge of misfolded proteins caused by heat, thus maintaining the equilibrium of intracellular protein metabolism. This analysis explores the function of Hsp72 in maintaining protein homeostasis, focusing on its ability to assist in the refolding of incorrectly folded proteins and to guide their breakdown through the ubiquitin-proteasome and autophagy systems. Furthermore, the potential mechanisms through which cells may eliminate misfolded protein aggregates via the secretory autophagy pathway under heat stress conditions are explored. This study systematically analyzes the various mechanisms by which Hsp72 influences misfolded protein metabolism and discusses the relevance of each pathway in the context of heat stress. Integrating findings from prior laboratory research, it is concluded that Hsp72 plays a pivotal role in regulating misfolded protein metabolism through the secretory autophagy pathway, thereby sustaining intracellular protein homeostasis during heat stress. This investigation expands the functional network of Hsp72 in maintaining protein homeostasis and elucidates the molecular pathways involved in its regulation of misfolded protein metabolism under heat stress, providing a framework for future research on Hsp72's role in cellular recovery from heat stress.\n\nID: 40899340\nTitle: The Therapeutic Potential of Flavonols in Alzheimer's Disease: Inhibiting Amyloid-\u03b2, Oxidative Stress, and Neuroinflammation.\nAbstract: Alzheimer's disease (AD), a progressive neurodegenerative disorder characterized by amyloid-\u03b2 (A\u03b2) aggregation, oxidative stress, and neuroinflammation, remains a significant global health challenge. This study investigates the therapeutic potential of flavonols-quercetin, kaempferol, myricetin, and fisetin-in targeting A\u03b2 aggregation and mitigating AD pathology through diverse molecular mechanisms. Our findings reveal that flavonols effectively inhibit A\u03b2 oligomerization and fibril formation, reduce oxidative stress via Nrf2/HO-1 pathway activation, and suppress neuroinflammation by modulating microglial polarization. Additionally, these compounds enhance mitochondrial function, promote autophagy-mediated clearance of A\u03b2 aggregates, and regulate key enzymes such as \u03b2-secretase (BACE1) and \u03b1-secretases (ADAM10/17), favoring non-amyloidogenic pathways. Quercetin demonstrated neuroprotective effects by activating TrkB signaling, reducing tau phosphorylation, and enhancing synaptic plasticity. Kaempferol prevented A\u03b2-induced apoptosis via the ER/ERK/MAPK pathway and inhibited acetylcholinesterase activity, improving cognitive outcomes. Myricetin ameliorated mitochondrial dysfunction and oxidative damage through GSK3\u03b2/ERK2 signaling modulation and showed enhanced brain bioavailability when delivered via nanostructured lipid carriers. Fisetin reduced A\u03b2 burden by upregulating neprilysin expression, suppressed neuroinflammation, and improved synaptic function by restoring synaptic protein levels. Overall, flavonols exhibit multi-targeted therapeutic potential against AD by addressing its complex pathogenesis. Their ability to cross the blood-brain barrier and low toxicity profiles position them as promising candidates for further clinical development. This study underscores the potential of flavonols as natural agents for AD treatment and highlights their role in advancing multi-mechanistic therapeutic strategies.\n\nID: 40872994\nTitle: Salmonella Typhimurium exploits the reticulophagy/ERphagy receptor RETREG1 to promote infection.\nAbstract: Macroautophagy/autophagy is a key catabolic-recycling pathway that can selectively target damaged organelles or invading pathogens for degradation. The selective autophagic degradation of the endoplasmic reticulum, called reticulophagy/ERphagy, controls ER size and degradation of misfolded protein aggregates. RETREG1/FAM134B is an ERphagy receptor that acts by inducing ER membrane curvature and scission through oligomerization. Interestingly, RETREG1\u00a0has also been implicated in the cellular response against pathogen infection. Multiple microbes have developed strategies to inhibit ERphagy by targeting RETREG1. In a recent study, we characterized an unidentified mechanism of bacterial-mediated inhibition of ERphagy. Specifically, we found that Salmonella enterica Serovar Typhimurium, a well-known intracellular pathogen that continues to be a major cause of foodborne infections worldwide, inhibits ERphagy by specifically targeting the activity of RETREG1, leading to a pronounced increase in Salmonella burden. We show that Salmonella prevents RETREG1 oligomerization, which is required for efficient ERphagy. Conversely, Salmonella-mediated ERphagy blockage can be bypassed by promoting RETREG1 oligomerization, which recovers ERphagy levels. Salmonella infection also decreases RETREG1 phosphorylation and acetylation, previously reported to be requisite steps in RETREG1-driven ERphagy. Furthermore, in vivo analysis of retreg1 knockout mice infected with Salmonella reveals increased intestinal damage and bacterial levels. Our results provide insights into the interplay between ERphagy and bacterial infection, highlighting a key role for RETREG1 in innate immunity.\n\nID: 40744389\nTitle: Natural bioactive compounds as modulators of autophagy: A herbal approach to the management of neurodegenerative diseases.\nAbstract: Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Polyglutamine (polyQ), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS) disease are a significant health concern that affects millions of people every year worldwide. The main pathological hallmark of various NDs is the formation of misfolded protein aggregation and accumulation of inclusion bodies. These protein aggregates are mainly responsible for producing toxic effects and initiating neuronal cell death, ultimately promoting various NDs. On the other hand, the patients suffering from these kinds of diseases live in impaired conditions, imposing a substantial financial burden on the family. However, the current treatment strategies can only offer temporary relief from the disease symptoms and can't reverse the disease completely. Hence, there is an urgent need for specific and novel drug treatment that can significantly eradicate NDs. Ubiquitin proteasome system (UPS) and autophagy are the two essential intracellular defensive mechanisms that are involved in clearing the protein aggregates, pathogens, and damaged organelles from the cytoplasm and maintaining protein homeostasis. Nevertheless, UPS is inefficient in removing some kinds of organelles and aggregating-prone proteins, specifically in neuronal and glial cells. Under this kind of circumstance, the autophagy mechanism plays a vital role in eliminating the accumulated protein aggregates and other toxic elements from the cytoplasm of the neuronal cells that initiate oxidative stress. However, in NDs, the autophagy function is impaired, and the protein aggregates can't be eliminated effectively. Hence, forced up-regulation of autophagy function by applying various external agents could be a potential therapeutic strategy to control NDs like AD, PD, HD, and ALS. In this review, we focused on different kinds of plant-derived compounds that induce autophagy. We also discussed the role of these plant-derived autophagy modulators in various NDs. In this way, the current review will be a standalone reference to the researchers working in this area.\n\nID: 40678709\nTitle: Chinese medicine monomers for hepatocellular carcinoma: New ideas related to autophagy.\nAbstract: Hepatocellular carcinoma (HCC) represents the most prevalent form of primary liver cancer, characterized by high mortality rates, frequent recurrence and metastasis, poor clinical prognosis, and a complex pathogenesis with limited therapeutic options. Autophagy plays a pivotal role in the immune response and functions as a lysosome-mediated degradation mechanism essential for recycling cellular components and eliminating aggregated proteins, damaged organelles, and invasive pathogens, thereby maintaining cellular function and dynamic homeostasis. Additionally, autophagy regulates several critical proteins and signaling pathways, including mammalian target of the rapamycin (mTOR), Beclin-1, the phosphatidylinositol 3-kinase/protein kinase B/mTOR signaling pathway, the Hippo/yes-associated protein signaling pathway, and the Janus kinase/signal transducer of activation signaling pathway. This regulatory capacity of autophagy can potentially prevent or delay the progression of HCC. Nowadays, many studies have shown that different types of herbal monomers such as the more common quercetin, baicalein, berberine and emodin can further regulate autophagy and exert preventive and therapeutic effects on HCC through the modulation of mTOR and other related signaling pathways and so on. In this paper, we examine the mechanisms of autophagy, key proteins and signaling pathways involved, and the modulation of autophagy by Chinese medicine monomers in the prevention and treatment of HCC. This review aims to provide valuable insights for the development of Chinese medicine strategies against HCC and to inform the rational use of these therapies in clinical practice.\n\nID: 40415242\nTitle: Endoplasmic reticulum tubule junctions are sites of autophagy.\nAbstract: Selective endoplasmic reticulum (ER) macroautophagy/autophagy, also called reticulophagy, is a disposal pathway that degrades ER domains. A major role of reticulophagy is the removal of ER domains that contain misfolded proteins resistant to ER-associated degradation (ERAD). Our studies have shown that RTN3L, the SEC24C-SEC23 COPII coat subcomplex, and the CUL3KLHL12 E3 ligase that ubiquitinates RTN3L targets ERAD-resistant misfolded protein condensates for degradation at ER-reticulophagy sites (ERPHS), autophagic sites that form at tubule junctions. Unexpectedly, we found that the Parkinson disease protein PINK1 regulates ER tubulation. Loss of PINK1 disrupts the formation of peripheral tubule junctions, and, as a consequence, reticulophagy is blocked and misfolded proteins accumulate in the ER. Overexpression of the ER tubulating domain of DNM1L/DRP1, a multifunctional PINK1 kinase substrate that localizes to ER-mitochondria contact sites, increases junctions and restores reticulophagy. Our findings show that PINK1 shapes the ER to target misfolded proteins for RTN3L-SEC24C-mediated macroreticulophagy at defined ER sites, peripheral tubule junctions.\n\nID: 40351085\nTitle: Neuroprotective Potential of the Flavonoids Quercetin and Epicatechin in a C. elegans Tauopathy Model.\nAbstract: The prevalence of cognitive disorders such as Alzheimer's disease (AD) is increasing due to the global rise in longevity. The accumulation of amyloid \u03b2 (A\u03b2) deposits and hyperphosphorylated Tau protein (p-Tau) are considered the main hallmarks of AD. A growing body of evidence suggests that the regular intake of flavonoid-rich foods could reduce the risk of developing AD or mitigate its progression. This study explores the potential of quercetin (Q) and epicatechin (EC) as effective molecules against AD-like pathology, using the Caenorhabditis elegans BR5270 strain, which expresses the pro-aggregant F3DK280 fragment of the human Tau protein. The results showed that after exposure to 150\u00a0\u00b5M of EC or Q, worms exhibited increased lifespan, improved chemotaxis, and delayed age-related decline in locomotion. To explore the molecular mechanisms involved, the expression of genes associated with the inhibition of p-Tau proteotoxicity were measured by RT-qPCR. It was found that Q and EC significantly increased the expression levels of autophagy-related genes and of a key gene for de novo synthesis of \u03b1- tubulin. EC and Q delay neurodegeneration in the C. elegans tauopathy model, suggesting their potential to reduce the risk of AD progression.\n\nID: 40332143\nTitle: p.Phe508del-CFTR Trafficking: A Protein Quality Control Perspective Through UPR, UPS, and Autophagy.\nAbstract: Cystic fibrosis (CF) is a genetic disease due to mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The most frequent mutation (p.Phe508del) results in a misfolded protein (p.Phe508del-CFTR) with an altered transport to the membrane of the cells via the conventional protein secretion (CPS) pathway. Nevertheless, it can use unconventional protein secretion (UPS). Indeed, p.Phe508del-CFTR forms a complex with GRASP55 to assist its direct trafficking from the endoplasmic reticulum to the plasma membrane. While GRASP55 is a key player of UPS, it is also a key player of stress-induced autophagy. In parallel, the unfolded protein response (UPR), which is activated in the presence of misfolded proteins, is tightly linked to UPS and autophagy through the key effectors IRE1, PERK, and ATF6. A better understanding of how UPS, UPR, and stress-induced autophagy interact to manage protein trafficking in CF and other conditions could lead to novel therapeutic strategies. By enhancing or modulating these pathways, it may be possible to increase p.Phe508del-CFTR surface expression. In summary, this review highlights the critical roles of UPS- and UPR-induced autophagy in managing protein transport, offering new perspectives for therapeutic approaches.\n\nID: 40133256\nTitle: The ER-phagy receptor FAM134B is targeted by Salmonella Typhimurium to promote infection.\nAbstract: Macroautophagy/autophagy is a key catabolic-recycling pathway that can selectively target damaged organelles or invading pathogens for degradation. The selective autophagic degradation of the endoplasmic reticulum (hereafter referred to as ER-phagy) is a homeostatic mechanism, controlling ER size, the removal of misfolded protein aggregates, and organelle damage. ER-phagy can also be stimulated by pathogen infection. However, the link between ER-phagy and bacterial infection remains poorly understood, as are the mechanisms evolved by pathogens to escape the effects of ER-phagy. Here, we show that Salmonella enterica serovar Typhimurium inhibits ER-phagy by targeting the ER-phagy receptor FAM134B, leading to a pronounced increase in Salmonella burden after invasion. Salmonella prevents FAM134B oligomerization, which is required for efficient ER-phagy. FAM134B knock-out raises intracellular Salmonella number, while FAM134B activation reduces Salmonella burden. Additionally, we found that Salmonella targets FAM134B through the bacterial effector SopF to enhance intracellular survival through ER-phagy inhibition. Furthermore, FAM134B knock-out mice infected with Salmonella presented severe intestinal damage and increased bacterial burden. These results provide mechanistic insight into the interplay between ER-phagy and bacterial infection, highlighting a key role for FAM134B in innate immunity.\n\nID: 40069115\nTitle: Self-Assembly of Short Peptides Activates Specific ER-Phagy and Induces Pyroptosis for Enhanced Tumor Immunotherapy.\nAbstract: Developing specific endoplasmic reticulum-autophagy (ER-phagy) inducers is highly desirable for discovering new ER-phagy receptors and elucidating the detailed ER-phagy mechanism and potential cancer immunotherapy. However, most of the current ER-phagy-inducing methods cause nonselective autophagy of other organelles. In this work, we report the design and synthesis of simple and stable short peptides (D-FFxFFs) that could specifically trigger ER-phagy, which further induces pyroptosis and activates the immune response against tumor cells. D-FFxFFs locate preferentially in ER and readily self-assemble to form nanosized misfolded protein mimics, which lead to distinct upregulation of dedicated ER-phagy receptors with no obvious autophagy of other organelles. Significant unfolded protein response (UPR) is activated via IRE1-JNK and PERK-ATF4 pathways. Interestingly, the persistent ER-phagy triggers ER Ca2+ release and a surge in mitochondrial Ca2+ levels, resulting in GSDMD-mediated pyroptosis other than apoptosis. The ER-phagy induces pyroptosis and activates a distinct antitumor immune response without evolving the acquired drug resistance. This work not only provides a powerful tool for investigating the mechanism and function of ER-phagy but also offers an appealing strategy for anticancer immunotherapy.\n\nID: 40047433\nTitle: Targeted Degradation Technology Based on the Autophagy-Lysosomal Pathway: A Promising Strategy for Treating Preeclampsia.\nAbstract: In recent years, targeted protein degradation (TPD) strategies leveraging the autophagy-lysosomal pathway (ALP) have transcended the limitations of conventional drug molecules, emerging as a highly promising approach for selectively eliminating disease-related proteins via the cell's intrinsic degradation machinery. These TPD methods, such as autophagosome-tethering compounds (ATTEC), autophagy-targeting chimera (AUTAC), AUTOphagy-TArgeting chimera (AUTOTAC), and chaperone-mediated autophagy (CMA) targeting chimera, exhibit efficacy in degrading misfolded protein aggregates associated with neurodegenerative disorders. Moreover, the excessive accumulation of misfolded proteins or protein complexes in the placenta has been identified as a significant contributor to preeclampsia (PE). Given the lack of effective treatments for PE, the application of autophagy-mediated TPD technology presents a novel therapeutic avenue. This review draws parallels between misfolded protein aggregates in neurodegenerative diseases and placenta-derived PE, integrating a substantial number of full-text studies. By harnessing TPD technologies grounded in the ALP, these autophagic degraders offer a pioneering approach for targeted therapy in PE by dismantling potential targets. Presently, there is limited exploration of ALP technology for identifying target proteins in the placenta. Nonetheless, we have proposed several potential target proteins, laying the groundwork for future therapeutic endeavors.\n\nID: 39946767\nTitle: Quercetin inhibits oligodendrocytes ferroptosis by blocking NCOA4-mediated ferritinophagy.\nAbstract: Ferritinophagy is a specific type of autophagy that maintains intracellular iron metabolic homeostasis by targeting ferritin, one of the major forms of iron storage in the human body. Previous research has demonstrated that quercetin prevents the ferroptosis of oligodendrocyte progenitor cells (OPCs) by inhibiting the Id2/transferrin pathway. Given the ability of quercetin to suppress autophagy in spinal cord injury (SCI), this study aimed to investigate whether quercetin prevents ferroptosis in an autophagy-dependent manner. In erastin-treated OPCs, quercetin significantly upregulated the protein level of ferritin heavy chain (FTH) and markedly reduced its colocalization with LysoTracker, an indicator of lysosome aggregation. Quercetin significantly reduced the ferrous iron levels, the LC3II/LC3I ratio, and the number of LC3 puncta in OPCs, whereas it increased the level of sequestosome 1 (P62) in erastin-treated OPCs. Pretreatment of OPCs with autophagy inhibitor bafilomycin A1 inhibited quercetin-mediated ferritinophagy and ferroptosis, whereas pretreatment with autophagy activator rapamycin reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, as evidenced by reduced protein levels of ferritin heavy chain and p62, as well as increased protein levels of LC3II/LC3I and prostaglandin-endoperoxide synthase 2 (PTGS2). Compared with the erastin and quercetin treated OPCs, increased rerrous iron, lipid peroxidation production, and decreased GSH content, as well as shrunken mitochondria, were observed in OPCs treated with a combination of erastin, quercetin, and rapamycin. In vivo, quercetin significantly downregulated the nuclear receptor coactivator 4 (NCOA4) and PTGS2 protein expression, as well as the LC3II/LC3I ratio. Besides that, quercetin reduced the MDA level and the colocalization of FTH with NCOA4 in spinal cord tissues. Mechanistically, NCOA4 reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, whereas mutation of Y71 to alanine only slightly reversed the above effect. In conclusion, our findings revealed that quercetin inhibits OPCs ferroptosis by blocking NCOA4-mediated ferritinophagy. Quercetin and ferritinophagy may be potential therapeutic agents for SCI.\n\nID: 39920690\nTitle: uN2CpolyG-mediated p65 nuclear sequestration suppresses the NF-\u03baB-NLRP3 pathway in neuronal intranuclear inclusion disease.\nAbstract: Neuronal intranuclear inclusion disease (NIID) is genetically linked to CGG repeat expansion in the 5'-untranslated region of the NOTCH2NLC gene, with nascent polyglycine-containing protein (uN2CpolyG) identified as a primary pathogenic factor. Emerging clinical evidence suggests that inflammation contributes to NIID pathogenesis, yet the underlying molecular mechanisms remain elusive. This study aimed to elucidate the molecular interaction between uN2CpolyG and the NF-\u03baB-NLRP3 pathway. Single-cell RNA sequencing was conducted on the skin tissues of NIID patients to assess changes in the expression of genes involved in inflammatory pathways. Cell models (HEK-293T and U87-MG) transfected with CGG9/69/100 expansion vectors were used to investigate alterations in the NF-\u03baB-NLRP3-autophagy pathway. Additionally, the therapeutic potential of NF-\u03baB activators was evaluated in a Drosophila model with a CGG expansion knock-in. Single-cell sequencing revealed a significant reduction in the expression of NFKBIA, encoding NF-\u03baB inhibitor alpha (IkBa), which facilitates the nuclear translocation of p65, a key NF-\u03baB component. uN2CpolyG directly interacted with and sequestered p65 in nuclear inclusions, leading to reduced phosphorylated p65 (p-p65) levels. This sequestration significantly downregulated the NF-\u03baB-NLRP3 pathway, impairing autophagy, as indicated by decreased LC3II/LC3I ratios. Treatment of CGG100 cells with lipopolysaccharide (LPS) significantly increased p-p65, NLRP3, and LC3II/LC3I levels while reducing insoluble uN2CpolyG levels and intranuclear inclusions. In the Drosophila knock-in model, LPS significantly reduced the number of intranuclear inclusions and improved phenotypic manifestations. This study revealed that uN2CpolyG directly interacts with and sequesters p65, thereby inhibiting the NF-\u03baB-NLRP3 pathway and impairing autophagy. This mechanism highlights a novel therapeutic target for NIID and provides potentially broader insights into similar mechanisms in other neurodegenerative diseases characterized by misfolded protein aggregates.\n\nID: 39842372\nTitle: Quercetin inhibits platelet activation and ER-stress mediated autophagy in response to extracellular histone.\nAbstract: Cellular histones are DNA-binding nuclear proteins involved in chromatin remodelling and regulation of gene expression. However, extracellular histones act as damage-associated molecular patterns (DAMPs) and contribute to multiorgan damage in conditions with sepsis and diseases with acute critical illnesses. Alongside, histones are associated with thrombocytopenia due to dysfunctional platelets that regulate hemostasis and thrombosis. There is no drug available to prevent histone-induced platelet toxicity. Therefore, we for the first time examined quercetin (QUE) as a novel therapeutic to protect histone-induced platelet toxicity. To delineate how histones induce platelet toxicity and investigate the protective efficacy of quercetin (QUE), a natural dietary phytochemical. Histone-treated platelets were evaluated for platelet aggregation/activation markers, various autophagy-related signaling proteins, and cytotoxicity in vitro. For the inhibition study, QUE and other standard inhibitors were pre-treated before stimulation with histones. Further, we injected histones into mice in the presence or absence of QUE and evaluated the tail bleeding, lung toxicity, and circulatory platelet stress markers. Additionally, QUE-treated mice were challenged for histone-primed Collagen-epinephrine-induced pulmonary thromboembolism. Extracellular histones induce platelet activation and aggregation by interacting with sialic acid in TLR1/2 or TLR4. Also, we have demonstrated for the first time that histones induce ER stress-mediated autophagy in platelets. QUE inhibited histone-induced platelet activation, aggregation, and ER-stress-mediated autophagy in response to histone treatment. Ex vivo experiments indicate that oral administration of QUE can safeguard platelets while concurrently mitigating their response to histone stimulation. In addition, quercetin increased the survival rates of histone-primed, collagen-epinephrine-induced acute pulmonary thromboembolism in mice. In summary, this study demonstrated the beneficial effect of QUE in protecting platelets with possible implications for addressing histone-accelerated pathologies.\n\nID: 39743298\nTitle: Autophagy receptor-inspired chimeras: a novel approach to facilitate the removal of protein aggregates and organelle by autophagy degradation.\nAbstract: Neurodegenerative diseases (NDDs), mainly including Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), and Alzheimer's disease (AD), are sporadic and rare genetic disorders of the central nervous system. A key feature of these conditions is the slow accumulation of misfolded protein deposits in brain neurons, the excessive aggregation of which leads to neurotoxicity and further disorders of the nervous system.\n\nID: 39617269\nTitle: Quiescent cells maintain active degradation-mediated protein quality control requiring proteasome, autophagy, and nucleus-vacuole junctions.\nAbstract: Many cells spend a major part of their life in quiescence, a reversible state characterized by a distinct cellular organization and metabolism. In glucose-depleted quiescent yeast cells, there is a metabolic shift from glycolysis to mitochondrial respiration, and a large fraction of proteasomes are reorganized into cytoplasmic granules containing disassembled particles. Given these changes, the operation of protein quality control (PQC) in quiescent cells, in particular the reliance on degradation-mediated PQC and the specific pathways involved, remains unclear. By examining model misfolded proteins expressed in glucose-depleted quiescent yeast cells, we found that misfolded proteins are targeted for selective degradation requiring functional 26S proteasomes. This indicates that a significant pool of proteasomes remains active in degrading quality control substrates. Misfolded proteins were degraded in a manner dependent on the E3 ubiquitin ligases Ubr1 and San1, with Ubr1 playing a dominant role. In contrast to exponentially growing cells, the efficient clearance of certain misfolded proteins additionally required intact nucleus-vacuole junctions (NVJ) and Cue5-independent selective autophagy. Our findings suggest that proteasome activity, autophagy, and NVJ-dependent degradation operate in parallel. Together, the data demonstrate that quiescent cells maintain active PQC that relies primarily on selective protein degradation. The necessity of multiple degradation pathways for the removal of misfolded proteins during quiescence underscores the importance of misfolded protein clearance in this cellular state.\n\nID: 39596274\nTitle: Manganese Exposure Enhances the Release of Misfolded \u03b1-Synuclein via Exosomes by Impairing Endosomal Trafficking and Protein Degradation Mechanisms.\nAbstract: Excessive exposure to manganese (Mn) increases the risk of chronic neurological diseases, including Parkinson's disease (PD) and other related Parkinsonisms. Aggregated \u03b1-synuclein (\u03b1Syn), a hallmark of PD, can spread to neighboring cells by exosomal release from neurons. We previously discovered that Mn enhances its spread, triggering neuroinflammatory and neurodegenerative processes. To better understand the Mn-induced release of exosomal \u03b1Syn, we examined the effect of Mn on endosomal trafficking and misfolded protein degradation. Exposing MN9D dopaminergic neuronal cells stably expressing human wild-type (WT) \u03b1Syn to 300 \u03bcM Mn for 24 h significantly suppressed protein and mRNA expression of Rab11a, thereby downregulating endosomal recycling, forcing late endosomes to mature into multivesicular bodies (MVBs). Ectopic expression of WT Rab11a significantly mitigated exosome release, whereas ectopic mutant Rab11a (S25N) increased it. Our in vitro and in vivo studies reveal that Mn exposure upregulated (1) mRNA and protein levels of endosomal Rab27a, which mediates the fusion of MVBs with the plasma membrane; and (2) expression of the autophagosomal markers Beclin-1 and p62, but downregulated the lysosomal marker LAMP2, thereby impairing autophagolysosome formation as confirmed by LysoTracker, cathepsin, and acridine orange assays. Our novel findings demonstrate that Mn promotes the exosomal release of misfolded \u03b1Syn by impairing endosomal trafficking and protein degradation.\n\nID: 39562539\nTitle: Advanced glycation end-products accelerate amyloid deposits in adipocyte's lipid droplets.\nAbstract: Adipose tissue dysfunction is central to insulin resistance, and the emergence of type 2 diabetes (T2D) is associated with elevated levels of carbonyl metabolites from glucose metabolism. In this study, using methylglyoxal (MGO) and glycolaldehyde (GAD) carbonyl metabolites induced protein glycation, leading to misfolding and \u03b2-sheet formation and generation of advanced glycation end products (AGEs). The formed AGEs compromise adipocytes activity. Microscopic and spectroscopic assays were used to examine the impact of MGO and GAD on lipid droplet-associated proteins. The results provide information about how these conditions lead to the appearance of glycated and amyloidogenic proteins formation that hinders metabolism and autophagy in adipocytes. We measured the beneficial effects of metformin (MET), an anti-diabetic drug, on misfolded protein as assessed by thioflavin (ThT) spectroscopy and improved autophagy, determined by LC3 staining. In vitro findings were complemented by in vivo analysis of white adipose tissue (WAT), where lipid droplet-associated \u03b2-amyloid deposits were predominantly linked to adipose triglyceride lipase (ATGL), a lipid droplet protein. Bioinformatics, imaging, biochemical and MS/MS methods affirm ATGL's glycation and its role in \u03b2-sheet secondary structure formation. Our results highlighted the pronounced presence of amyloidogenic proteins in adipocytes treated with carbonyl compounds, potentially reshaping our understanding of adipocyte altered activity in the context of T2D. This in-depth exploration offers novel perspectives on related pathophysiology and underscores the potential of adipocytes as pivotal therapeutic targets, bridging T2D, amyloidosis, protein glycation, and adipocyte malfunction.\n\nID: 39551160\nTitle: Targeted protein degradation: expanding the technology to facilitate the clearance of neurotoxic proteins in neurodegenerative diseases.\nAbstract: In neurodegenerative diseases (NDDs), disruptions in protein homeostasis hinder the clearance of misfolded proteins, causing the formation of misfolded protein oligomers and multimers. The accumulation of these abnormal proteins results in the onset and progression of NDDs. Removal of non-native protein is essential for cell to maintain proteostasis. In recent years, targeted protein degradation (TPD) technologies have become a novel means of treating NDDs by removing misfolded proteins through the intracellular protein quality control system. The TPD strategy includes the participation of two primary pathways, namely the ubiquitin-proteasome pathway (for instance, PROTAC, molecular glue and hydrophobic tag), and the autophagy-lysosome pathway (such as LYTAC, AUTAC and ATTEC). In this review, we systematically present the mechanisms of various TPD strategies employed for neurotoxic protein degradation in NDDs. The article provides an overview of the design, in vitro and in vivo anti-NDD activities and pharmacokinetic properties of these small-molecular degraders. Finally, the advantages, challenges and perspectives of these TPD technologies in NDDs therapy are discussed, providing ideas for further development of small molecule degraders in the realm of NDDs.\n\nID: 39480084\nTitle: Tripartite motif 25 inhibits protein aggregate degradation during PRRSV infection by suppressing p62-mediated autophagy.\nAbstract: Viral infection causes endoplasmic reticulum stress and protein metabolism disorder, influencing protein aggregates formation or degradation that originate from misfolded proteins. The mechanism by which host proteins are involved in the above process remains largely unknown. The present study found that porcine reproductive and respiratory syndrome virus (PRRSV) infection promoted the degradation of intracellular ubiquitinated protein aggregates via activating autophagy. The host cell E3 ligase tripartite motif-containing (TRIM)25 promoted the recruitment and aggregation of polyubiquitinated proteins and impeded their degradation caused by PRRSV. TRIM25 interacted with ubiquitinated aggregates and was part of the aggregates complex. Next, the present study investigated the mechanisms by which TRIM25 inhibited the degradation of protein aggregates, and it was found that TRIM25 interacted with both Kelch-like ECH-associated protein 1 (KEAP1) and nuclear factor E2-related factor 2 (Nrf2), facilitated the nuclear translocation of Nrf2 by targeting KEAP1 for K48-linked ubiquitination and proteasome degradation, and activated Nrf2-mediated p62 expression. Further studies indicated that TRIM25 interacted with p62 and promoted its K63-linked ubiquitination via its E3 ligase activity and thus caused impairment of its oligomerization, aggregation, and recruitment for the autophagic protein LC3, leading to the suppression of autophagy activation. Besides, TRIM25 also suppressed the p62-mediated recruitment of ubiquitinated aggregates. Activation of autophagy decreased the accumulation of protein aggregates caused by TRIM25 overexpression, and inhibition of autophagy decreased the degradation of protein aggregates caused by TRIM25 knockdown. The current results also showed that TRIM25 inhibited PRRSV replication by inhibiting the KEAP1-Nrf2-p62 axis-mediated autophagy. Taken together, the present findings showed that the PRRSV replication restriction factor TRIM25 inhibited the degradation of ubiquitinated protein aggregates during viral infection by suppressing p62-mediated autophagy.IMPORTANCESequestration of protein aggregates and their subsequent degradation prevents proteostasis imbalance and cytotoxicity. The mechanisms controlling the turnover of protein aggregates during viral infection are mostly unknown. The present study found that porcine reproductive and respiratory syndrome virus (PRRSV) infection promoted the autophagic degradation of ubiquitinated protein aggregates, whereas tripartite motif-containing (TRIM)25 reversed this process. It was also found that TRIM25 promoted the expression of p62 by activating the Kelch-like ECH-associated protein 1 (KEAP1) and nuclear factor E2-related factor 2 (Nrf2) pathway and simultaneously prevented the oligomerization of p62 by promoting its K63-linked ubiquitination, thus suppressing its recruitment of the autophagic adaptor protein LC3 and ubiquitinated aggregates, leading to the inhibition of PRRSV-induced autophagy activation and the autophagic degradation of protein aggregates. The present study identified a new mechanism of protein aggregate turnover during viral infection and provided new insights for understanding the pathogenic mechanism of PRRSV.\n\nID: 39454200\nTitle: Role of Autophagy in Myocardial Remodeling After Myocardial Infarction.\nAbstract: Autophagy is the process of reusing the body's senescent and damaged cell components, which can be regarded as the cellular circulatory system. There are 3 distinct forms of autophagy: macroautophagy, microautophagy, and chaperone-mediated autophagy. In the heart, autophagy is regulated mainly through mitophagy because of the metabolic changes of cardiomyocytes caused by ischemia and hypoxia. Myocardial remodeling is characterized by gradual heart enlargement, cardiac dysfunction, and extraordinary molecular changes. Cardiac remodeling after myocardial infarction is almost inevitable, which is the leading cause of heart failure. Autophagy has a protective effect on myocardial remodeling improvement. Autophagy can minimize cardiac remodeling by preventing misfolded protein accumulation and oxidative stress. This review summarizes the nestest molecular mechanisms of autophagy and myocardial remodeling, the protective effects, and the new target of autophagy medicine in cardiac remodeling. The future development and challenges of autophagy in heart disease are also summarized.\n\nID: 39113571\nTitle: Pharmacological inhibition of USP14 delays proteostasis-associated aging in a proteasome-dependent but foxo-independent manner.\nAbstract: Aging is often accompanied by a decline in proteostasis, manifested as an increased propensity for misfolded protein aggregates, which are prevented by protein quality control systems, such as the ubiquitin-proteasome system (UPS) and macroautophagy/autophagy. Although the role of the UPS and autophagy in slowing age-induced proteostasis decline has been elucidated, limited information is available on how these pathways can be activated in a collaborative manner to delay proteostasis-associated aging. Here, we show that activation of the UPS via the pharmacological inhibition of USP14 (ubiquitin specific peptidase 14) using IU1 improves proteostasis and autophagy decline caused by aging or proteostatic stress in Drosophila and human cells. Treatment with IU1 not only alleviated the aggregation of polyubiquitinated proteins in aging Drosophila flight muscles but also extended the fly lifespan with enhanced locomotive activity via simultaneous activation of the UPS and autophagy. Interestingly, the effect of this drug disappeared when proteasomal activity was inhibited, but was evident upon proteostasis disruption by foxo mutation. Overall, our findings shed light on potential strategies to efficiently ameliorate age-associated pathologies associated with perturbed proteostasis.Abbreviations: AAAs: amino acid analogs; foxo: forkhead box, sub-group O; IFMs: indirect flight muscles; UPS: ubiquitin-proteasome system; USP14: ubiquitin specific peptidase 14.\n\nID: 42407185\nTitle: Deep learning of multiplexed mitochondrial morphology identified natural compound combinations against skin photoaging.\nAbstract: Skin photoaging is primarily driven by mitochondrial dysfunction. Although natural products have demonstrated protective effects against Ultraviolet (UV)-induced damage, efficient screening strategies for mitochondrial-targeting compounds remain limited. Artificial Intelligence (AI)-assisted high-content screening strategy offers a valuable approach to identify bioactive candidates and elucidate their mechanisms. This study aimed to employe an AI-assisted high-content screening strategy to identify mitochondrial-enhancing natural compounds that prevent skin photoaging and to evaluate their protective efficacy. This study employed an AI-assisted high-content screening strategy to identify mitochondria-targeting compounds that mitigate photodamage. UVB-induced models were established in cells, zebrafish, and mice with UVB lamp irradiation. Mitochondrial morphology and function were quantified using JC-1, TMRM, and MitoTracker probes. Cell viability, SA-\u03b2-gal activity, and protein expression were assessed by CCK-8 assay, SA-\u03b2-gal staining, and Western blotting, respectively. Using AI-assisted high-content screening, we identified quercetin, spermidine, adenosine, Vitamin K2, and Mirabilis jalapa extract as mitochondrial protective compounds. Two optimized combinations, CC-1 and CC-2, restored ATP production, TCA cycle flux, and mitochondrial morphology in UVB-exposed human dermal fibroblasts (HDFs), reduced SA-\u03b2-gal activity, and upregulated COLLAGEN I, LAMIN B1, and SIRT3 expression. Both combinations alleviated the UVB-induced senescence phenotype by upregulating SIRT3. In a UVB-exposed zebrafish tail amputation model, CC-2 markedly promoted fin regeneration. These findings were validated in UVB-irradiated mice, where CC-2 demonstrated superior efficacy. Using AI-assisted high-content screening, we formulated two optimized combinations that alleviate UVB-induced skin photoaging, with CC-2 exhibiting superior efficacy, highlighting its potential as cosmetic additive.\n\nID: 42407132\nTitle: Complexation between mannoprotein-grape polysaccharide nanoparticles and quercetin was associated with color restoration: A mechanistic exploration in model red wine solutions.\nAbstract: Different mannoprotein (MP)-grape polysaccharide (GP) nanoparticles (MGPN) were fabricated and complexed with quercetin to analyze their abilities and mechanisms in modulating the color of model red wine solutions (MRWS). MRWS showed yellowish hue recession of up to 92.52%, which should be associated with the complexation ability of MGPN towards quercetin. MGPN of 75% GP proportions with Ca2+ or K+ contained 2.2- to 10-fold or 1.64- to 4.48-fold higher quercetin than other MGPN counterparts, which conferred MRWS the highest and second highest yellowish hue recession rates, respectively. The surface hydrophobicity, Zeta-potential, and FTIR data together indicate that Ca2+ and K+ might strengthen the hydrogen bonds/electrostatic interactions and hydrophobic interactions between MGPN and quercetin, respectively. Molecular dynamic simulation suggests that increased GP proportions in MGPN with Ca2+ benefited quercetin complexation by improving 26.3%-40.48% structural stabilities and increasing 13.36%-40.1% complexed quercetin molecules in the MGPN-quercetin complexes, rather than enhancing the interaction energies.\n\nID: 42406931\nTitle: Hepatoprotective Effects of Baccaurea motleyana Fruit Extract Against CCl4-Induced Liver Injury in Rats: In Vivo Evaluation and GC-MS Phytochemical Profiling.\nAbstract: Over 25% of people worldwide have liver illnesses, which kill nearly 2 million. This study assessed the hepatoprotective potential of Baccaurea motleyana fruit acetone extract (BMF-AE) against CCl4-induced liver injury. GC-MS phytochemical profiling identified nine metabolites, with linoleic acid ethyl ester, quercetin, and gallic acid as predominant bioactives known for hepatoprotective activity. The antioxidant activity of BMF-AE was significant in DPPH and ABTS assays, with IC50 values of 112.55 and 127\u00a0\u00b5g/mL, respectively. In vivo hepatoprotective efficacy was assessed in five groups (n = 5) that received oral BMF-AE (200 or 400\u00a0mg/kg) for 14 days. Positive control was 100\u00a0mg/kg silymarin. The CCl4-induced increase in serum ALT, AST, ALP, and bilirubin was dramatically reduced, while BMF-AE restored albumin levels (p < 0.05). Treatment reduced hepatic TBARS and restored glutathione and catalase activity, reducing oxidative stress. Histopathological investigation demonstrated maintained liver architecture in treated rats. Molecular docking analysis revealed that quercetin and linoleic acid ethyl ester bind strongly to targets of oxidative stress and inflammation, including xanthine oxidoreductase, interleukin-6, tumor necrosis factor-\u03b1, and PARP-1, suggesting potential hepatoprotective effects. BMF-AE may be a promising natural therapy for oxidative stress-mediated liver injury, according to this study, due to its antioxidant phytoconstituents.\n\nID: 42406250\nTitle: REJENERA\u00a9, a multi-component bioflavonoid-based formula, alleviates osteoarthritis and provides chondroprotection by regulating the NLRP3-TXNIP-iNOS axis and inflammation: a comparative study with olive leaf nutraceuticals and ibuprofen.\nAbstract: Osteoarthritis (OA) primarly involves the degradation of joint cartilage and requires new treatments. REJENERA\u00a9, a newly developed nutraceutical formula against OA, contains primarily olive leaf bioflavonoids ( ZeyEX\u00a9, quercetin and luteolin), S-allylcysteine, palmitoylethanolamide, L-proline, hyaluronic acid and boron. This study focuses on the efficacy of REJENERA in treating knee OA and aims to compare it with ZeyEX, NPROC\u00a9 (a product obtained by combining collagen-rich eggshell membrane with olive leaf extract), and IBUPROFEN in a rat OA model. OA was established by intra-articular injection of monosodium iodoacetate (MIA; 3\u00a0\u00a0mg) into the right knee joints. Rats were either left untreated or treated orally for 12\u00a0weeks with REJENERA, ZeyEX, NPROC (300\u00a0mg/kg/day) or IBUPROFEN (3\u00a0mg/kg/day). MIA injection produced joint degeneration including increased fissure-index, osteophyte-score, and OARSI-score, joint swelling, synovial inflammation, proteoglycan loss, and decreased cartilage thickness. These histopathological abnormalities were partially but significantly alleviated by REJENERA and other treatments. Only ZeyEX significantly inhibited the OA-induced increase in IL-1\u03b2, IL-6, IL-10 and LPO in serum, and IL-6, TNF-\u03b1, and IFN-\u03b3 in synovial fluid. While increases in MMP-3 and MMP-9 were reduced with all treatments, MMP-13 was inhibited only by REJENERA. ZeyEX increased IL-2, NPROC increased IL-6, and IBUPROFEN inhibited IL-10. All treatments improved TIMP-1 levels; however, TXNIP was more significantly inhibited by ZeyEX, and NLRP3 by REJENERA. REJENERA's anti-OA effects are accompanied by an increase in cartilage anabolic factors (Ki-67, type-II collagen, BMP-7) and inhibition of apoptosis. REJENERA offers a promising multi-targeted therapeutic approach to treating OA by blocking the iNOS-TXNIP-NLRP3\u00a0signaling axis, and reducing oxidative stress.\n\nID: 42406229\nTitle: Safe and effective control of Mycoplasma gallisepticum: pharmacokinetic and residue profiling of doxycycline combined with quercetin nanomicelles.\nAbstract: Although doxycycline is widely used to combat Mycoplasma gallisepticum (MG), misuse promotes antimicrobial resistance. Quercetin exhibits antibacterial potential; however, its application is limited by poor bioavailability, and its nanomicelle-based delivery with doxycycline remains uninvestigated. This study evaluated the efficacy, pharmacokinetics, and residue depletion of doxycycline combined with quercetin and quercetin nanomicelles against MG infection in broilers using a validated green high-performance liquid chromatography approach. One-day-old chicks were divided into seven groups: negative and positive controls, and treatment groups that received doxycycline, quercetin, or quercetin nanomicelles orally at doses of 25, 50, and 50\u00a0mg/kg body weight, respectively, either alone or in combination, for five days post-challenge. Pharmacokinetic parameters and residue depletion were investigated in treated groups at multiple time points. Tracheal and lung samples were collected at two intervals for MG enumeration and virulence gene expression. Quercetin and its nanomicelles displayed minimum inhibitory concentrations (MICs) of 0.47 and 0.02\u00a0\u00b5g/mL, respectively; their combinations with doxycycline had fractional inhibitory concentration indices of 6 and 0.375, respectively. Nanomicelles were characterized by size, polydispersity index, zeta potential, and encapsulation efficiency values of 345.66\u00a0nm, 0.14, 19.1 mV, and 96.1%, respectively, with no cytotoxicity up to 8\u00d7 MIC. In vivo, the greatest reductions in MG counts and in mgc2, adrA, and crmA expression were observed in nanomicelle-treated groups. Co-administration of doxycycline with nanomicellar quercetin improved systemic exposure, prolonged serum persistence above the MIC, and supported extended dosing intervals while maintaining favorable tissue depletion profiles. Conversely, conventional quercetin negatively influenced doxycycline pharmacokinetics, causing therapeutic failure.\n\nID: 42406202\nTitle: Solvent-driven modulation of phenolic composition and biofunctional activities of three Mentha aquatica formulations: integrated in vitro and in silico insights.\nAbstract: The goal of this work was to examine the effect of different solvents (Water, EtOH 70%, and acetone) on the phenolic composition, antioxidant, and antibacterial capacity of Moroccan Mentha aquatica L. leaf extract. To this end, HPLC-ESI-FULL-MS was used to characterize the extracts, while the Folin-Ciocalteu and aluminum trichloride techniques were used to evaluate the total phenolic and flavonoid contents. To assess the antibacterial capacity, the microdilution technique was performed to calculate the minimal inhibition concentration (MIC), and minimal bactericidal concentration (MBC). Phytochemical profiling revealed that the extracts were rich in bioactive constituents, particularly ferulic acid derivative, caffeoyl-protocatechuic acid derivative, quercetin, and diosmetin 7-O-beta-D-glucuronide. The hydroethanolic extract contained the highest levels of total phenolic (62.2\u2009\u00b1\u20091.2\u00a0mg GAE/g DW) and flavonoid (29.15\u2009\u00b1\u20090.09\u00a0mg QE/g DW) contents, exceeding those of the acetonic extract (22.2\u2009\u00b1\u20090.6 and 10.17\u2009\u00b1\u20090.07\u00a0mg GAE/g DW, respectively) and the water extract (22.4\u2009\u00b1\u20090.6 and 10.9\u2009\u00b1\u20090.6\u00a0mg QE/g DW, respectively). This extract also showed the strongest antioxidant effect, recording an IC50 of 0.060\u2009\u00b1\u20090.001\u00a0mg/mL in the DPPH assay, and an EC50 of 80\u00a0\u00b5g/mL in the RP test. In addition, it shows a great total antioxidant capacity, reaching 75.1\u2009\u00b1\u20092.0\u00a0mg EAA/g DW when compared to water and acetonic extracts (28.5\u2009\u00b1\u20091.4 and 21.1\u2009\u00b1\u20090.1\u00a0mg EAA/g DW, respectively). The antibacterial potential ranges from 0.78\u2009\u00b1\u20090.05\u00a0mg/mL to 12.6\u00a0mg/mL. In-silico prediction highlighted diosmetin 7-O-beta-D-glucuronide, quercetin, and equisetumpyrone as the key contributors to antioxidant capacity, while quercetin, 2,3,8-Tri-O-methylellagic acid, and diosmetin 7-O-beta-D-glucuronide were involved in antibacterial activity.\n\nID: 42405384\nTitle: Plant-Derived Polyphenols in the Fight against Colorectal Cancer.\nAbstract: Colorectal cancer (CRC) is the third most common cancer worldwide and a leading cause of cancer-related mortality. Despite advances in surgery, chemotherapy, and targeted therapies, many CRC patients experience limited efficacy, toxicity, or drug resistance. Thus, complementary therapeutic strategies with an improved safety profile are needed. Plant-derived polyphenols emerge as promising candidates for CRC treatment. This review compiles in vitro, in vivo, and clinical evidence on the anticancer activity of polyphenols in CRC. Polyphenols, such as curcumin, resveratrol, quercetin, and flavonoids, are analyzed, with emphasis on molecular mechanisms and chemopreventive potential. In vitro studies consistently demonstrate that these compounds exert anticancer effects by modulating multiple pathways, including PI3K/AKT/mTOR, Wnt/\u03b2-catenin, STAT3, and MAPK/ERK, promoting apoptosis and regulating oxidative stress and inflammation. In vivo studies indicate that curcumin, resveratrol, quercetin, epigallocatechin gallate (EGCG), genistein, luteolin, and fisetin significantly reduce tumor volume, polyp formation, and aberrant crypt foci (ACF). Curcumin has been extensively evaluated in trials, with some studies demonstrating reductions in ACF and improvements in inflammatory markers and quality of life, while others have demonstrated no significant clinical benefit. Preclinical evidence supports the chemopreventive role of polyphenols. Preliminary clinical trials also suggest therapeutic potential for CRC prevention and treatment; however, large-scale, well-controlled clinical trials are required to confirm their safety and efficacy. Plant-derived polyphenols represent promising complementary strategies for CRC prevention and therapy. Future research should prioritize compounds with strong preclinical evidence, standardized formulations, optimized delivery strategies, and rigorously designed randomized trials to facilitate integration into clinical oncology practice.\n\nID: 42405051\nTitle: Design, synthesis, and biological evaluation of vanillin-piperidone hybrids with potent anticancer activity and a favourable genotoxic profile.\nAbstract: A new series of 1-ethoxycarbonyl-3,5-bis(benzyl/alkyl vanillin)-4-piperidone analogues were synthesized via a two-step process involving aldol condensation of vanillin with 1-ethoxycarbonyl-4-piperidone, followed by O-alkylation using diverse aromatic and aliphatic halides. Structural characterization of the resulting compounds (3 and 4a-4m) was confirmed by NMR and HR-MS analyses. Among the synthesized derivatives, compounds 3 and 4k exhibited the most potent and selective cytotoxicity. Compound 3 demonstrated IC50 values of 2.97 \u00b5M (SKBR3), 4.4 \u00b5M (DU145), and 20.5 \u00b5M (HEK-293), while compound 4k showed strong activity against HepG2 (2.27 \u00b5M) and DU145 (5.01 \u00b5M). Genotoxic assessment revealed that 4k maintained a favourable safety profile, with chromosomal aberration and micronucleus frequencies remaining low or only mildly elevated at higher doses, and a moderate, dose-dependent decrease in mitotic index. Mechanistic studies indicated G0/G1 cell cycle arrest in CHO-K1, DU145, and HepG2 cells, along with significant apoptosis induction in HepG2 (Sub-G1: 13.9%). Although its antioxidant potential was moderate relative to rutin, 4k exhibited dose-dependent free radical scavenging. Antidiabetic screening identified compounds 1, 3, 4c, and 4m as effective \u03b1-glucosidase inhibitors (52.6-58.5%; IC50 = 4.27-4.75 \u00b5g mL-1), comparable to acarbose. Antimicrobial evaluation showed broad-spectrum activity for compound 1, and compound 4k displayed membrane-stabilizing effects similar to quercetin. In conclusion, these multifunctional vanillin-piperidone hybrids especially compound 4k demonstrate significant anticancer, antidiabetic, and antimicrobial potential, further strengthened by their confirmed non-genotoxic profile.\n\nID: 42404793\nTitle: Effect of flavonoids identified in grape pomace extract on efflux pump in Staphylococcus aureus.\nAbstract: Overexpression of efflux pumps, is a primary mechanism of multidrug resistance in Staphylococcus aureus. This study evaluated grape pomace extracts and their constituent flavonoids as potential efflux pump inhibitors (EPIs) to restore ciprofloxacin susceptibility. RP-HPLC analysis of the extracts identified quercetin, (+)-catechin, and (-)-epicatechin. The synergistic interaction between these agents and ciprofloxacin was assessed using the checkerboard method against three S. aureus strains: NCTC 8325-4 (norA wild type), K2378 (overexpressing norA), and K1902 (norA deletion). Additionally, ethidium bromide accumulation assays were conducted to quantify pump inhibition activity. All extracts and identified flavonoids exhibited synergism with ciprofloxacin, yielding Fractional Inhibitory Concentration Indices (FICI) ranging from 0.076 to 0.281. While crude extracts demonstrated nonspecific pump inhibition, the isolated flavonoid (-)-epicatechin showed inhibitory activity against the NorA effux pump. Conversely, (+)-catechin and quercetin displayed lower, concentration-dependent activity. These findings demonstrate that grape pomace flavonoids, particularly (-)-epicatechin, act as effective EPIs capable of efflux pumps mediated resistance, suggesting their potential utility as adjuvants in antimicrobial therapy.\n\nID: 42404441\nTitle: Extraction of Soybean and Pea Protein Isolates to Evaluate Therapeutic Potential Against Dexamethasone-Induced Osteoporosis: In\u00a0Vivo and in Silico Insights.\nAbstract: Soybean and pea protein isolates contain essential amino acid that may support bone health, skeletal function and muscle performance. The current research examines the amino acid profile of SPI and PPI and evaluates their impact on bone health in\u00a0vivo and in silico. Female Sprague-Dawley rats were randomly assigned to four groups: T0 (Standard diet + without osteoporosis), T1 (Standard diet + osteoporosis), T2 (2\u2009g/kg bw of SPI+ 2\u2009g/kg bw of PPI), and T3 (3\u2009g/kg bw of SPI+ 3\u2009g/kg bw of PPI). Biochemical parameters and histopathology of bone (femur and tibia), liver, and kidney were evaluated. The amino acid profile demonstrated higher levels of glutamic and aspartic acids and a lower level of sulfur-containing amino acids. PPI exhibited higher content of arginine, lysine, and leucine than SPI. T3 significantly reduced the severity of disease compared with all other groups, as reflected in increased the osteocalcin levels (9.50\u2009\u00b1\u20091.85\u2009ng/mL), Ca (9.10\u2009\u00b1\u20091.06\u2009mg/dL), P (3.30\u2009\u00b1\u20090.08\u2009mg/dL), and lowering inflammatory levels of CRP (0.70\u2009\u00b1\u20090.04\u2009mg/L) and ESR (15.70\u2009\u00b1\u20091.58\u2009mm/h) in the respective treatment groups. Histological studies revealed no changes in bone, liver, and kidney tissues. Furthermore, molecular docking demonstrated potential interactions between gamma-carboxylase and ligands, such as genistein, \u03b2-sitosterol, glycitein, kaempferol, and quercetin, with binding affinities of -8.3, -9.0, -7.6, -7.6, and -8.1\u2009kcal/mol, respectively. These findings support the therapeutic potential of plant protein isolates in osteoporosis management; however, long-term in\u00a0vivo trials are required to validate the safety of isolates before moving toward human trials.\n\nID: 42402649\nTitle: Phytochemical profiling and systemic organoprotection of Tridax procumbens against cerebral ischemia-reperfusion injury.\nAbstract: Cerebral ischemia-reperfusion (I/R) injury triggers a systemic inflammatory response and a catastrophic respiratory burst of reactive oxygen species, resulting in widespread multi-organ damage. This study evaluated the phytochemical profile of Tridax procumbens ethanol extract (TP) and validated its multi-target, systemic organoprotective efficacy against cerebral I/R-induced cardiohepatorenal oxidative injury. TP constituents were identified using LC-MS profiling. Its in-vitro antioxidant metrics were quantified via DPPH, reducing power, and H2O2 scavenging assays. For in-vivo assessment, Wistar rats were subjected to 30\u00a0min of global cerebral ischemia via bilateral common carotid artery occlusion (BCCAO), followed by reperfusion. TP (20-80\u00a0mg/kg, i.p.) and quercetin (20\u00a0mg/kg, i.p.) was administered immediately at reperfusion. After 24\u00a0h, malondialdehyde (MDA) and reduced glutathione (GSH) were mapped across the heart, liver, and kidneys, alongside brain histopathology. LC-MS profiling identified 10 major phenolics and flavonoids, notably luteolin (37.32%), kaempferol (21.41%), and resveratrol (14.65%). In vitro, TP demonstrated significant antioxidant prowess, achieving 56.8% DPPH inhibition (50\u00a0\u00b5g/mL) and 86.98% H2O2 scavenging (10\u00a0\u00b5g/mL). In vivo, BCCAO caused severe cerebral injury and a systemic surge in lipid peroxidation paired with systemic GSH depletion. TP treatment significantly (P\u2009<\u20090.05) minimized multi-organ MDA accumulation, dose-dependently restored endogenous GSH pools across all harvested peripheral tissues, and preserved neuro-architectural integrity while reversing cerebral necrosis. TP exerts powerful multi-systemic protection by mitigating distant-organ oxidative bankruptcy and neuro-structural collapse, showcasing its potential as a natural therapeutic compound for complex vascular injuries.\n\nID: 42402230\nTitle: Quercetin suppresses TGF-\u03b21-induced proliferation and migration of vascular smooth muscle cells via the Smad2/3/MMP-9 signaling axis.\nAbstract: Aberrant proliferation and migration of vascular smooth muscle cells (VSMCs) are central to the pathogenesis of occlusive vascular diseases including atherosclerosis and restenosis. Quercetin, a naturally occurring flavonoid with established cardioprotective properties, has been reported to inhibit VSMC dysfunction, yet the underlying molecular mechanisms remain incompletely defined. Here, we demonstrate that quercetin dose-dependently suppresses TGF-\u03b21-induced proliferation and migration of human aortic VSMCs. Mechanistically, quercetin attenuates TGF-\u03b21-mediated phosphorylation of Smad2/3 and markedly reduces expression of matrix metalloproteinase-9 (MMP-9). Using the selective TGF-\u03b2 type I receptor inhibitor SB431542, we establish that MMP-9 expression in VSMCs is regulated through the canonical Smad2/3 signaling pathway. Rescue experiments with MMP-9 overexpression reversed the anti-proliferative and anti-migratory effects conferred by TGF-\u03b2 receptor blockade, confirming MMP-9 as an essential downstream effector. These findings delineate the TGF-\u03b21/Smad2/3/MMP-9 signaling axis as a molecular target of quercetin in VSMCs and provide mechanistic rationale for quercetin-based therapeutic strategies in vascular remodeling diseases.\n\nID: 42401646\nTitle: pH-sensitive gelatin-montmorillonite-cerium oxide nanocarriers for controlled quercetin delivery and machine learning release prediction.\nAbstract: In this study, a novel pH-responsive hybrid nanocarrier with a water-in-oil-in-water (W/O/W) emulsion structure was developed using gelatin (G) as a biocompatible polymer, montmorillonite (MMT) as a layered diffusion barrier, and cerium oxide nanoparticles (CeO\u2082) as a multifunctional stabilizing agent for pH-responsive and controlled delivery of quercetin (QC). The nanocarriers were synthesized via a double-emulsion method and comprehensively characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and dynamic light scattering (DLS) with zeta potential analysis. The optimized G/MMT/CeO2@QC nanocarriers exhibited a uniform nanoscale size (39.3\u00a0nm) and a high negative zeta potential (-\u200938.6 mV), indicating excellent colloidal stability. Incorporation of MMT and CeO\u2082 significantly enhanced drug loading and encapsulation efficiency (43.0% and 84.5%, respectively) compared to the MMT-free G/CeO\u2082@QC system, due to synergistic effects of layered silicate confinement, gelatin-mediated hydrogen bonding, and CeO2-driven Lewis acid-base coordination. In vitro release studies demonstrated pronounced pH sensitivity, with sustained release at physiological pH (60% at pH 7.4 after 96\u00a0h) and accelerated release under tumor-mimicking acidic conditions (95% at pH 5.4). To further interpret the release kinetics, machine learning-assisted, shape-constrained data analysis was employed to provide time-resolved and physically consistent insights into pH-dependent release behavior. Kinetic modeling confirmed Higuchi and Korsmeyer-Peppas-controlled diffusion mechanisms. Cytocompatibility and anticancer activity were evaluated using the MTT assay on A549 lung cancer cells and L929 fibroblasts. Blank nanocarriers were non-toxic (>\u200995% cell viability), while drug-loaded nanocarriers achieved selective cytotoxicity (A549 viability reduced to 55% with 93% viability in L929 cells), outperforming free QC. Overall, this tri-component hybrid system provides a multifunctional nanoscale platform with controlled drug release, high encapsulation efficiency, and tumor-selective cytotoxicity, demonstrating strong potential as a pH-responsive nanocarrier for lung cancer therapy.\n\nID: 42401520\nTitle: Corrigendum to \"Quercetin attenuates chondrocyte anoikis via modulation of mesenchymal stromal cell-derived small extracellular vesicles to promote cartilage repair in osteoarthritis\" [Phytomedicine 146 (2025) 157146].\nAbstract: \n\nID: 42401246\nTitle: The Modulation of RAGE by Natural Products and Traditional Medicines: Opening Promising Perspectives for Inflammatory Diseases.\nAbstract: Traditional and indigenous medical systems have a long history of using medicinal plants to treat conditions now understood as chronic inflammation. This ethnopharmacological knowledge provides a rich resource for discovering novel anti-inflammatory agents. This review critically evaluates the evidence for the modulation of the Receptor for Advanced Glycation End-products (RAGE) signaling pathway by natural products derived from traditional medicines, aiming to connect this traditional knowledge with modern molecular pharmacology. A comprehensive literature review was performed using the PubMed database. The search focused on keywords such as \"RAGE,\" \"natural products,\" and \"traditional medicine\" to identify studies detailing the mechanistic interactions between natural compounds and the RAGE pathway. Natural products, including polyphenols, terpenoids, and alkaloids, modulate the RAGE axis through several key mechanisms: (1) inhibiting the formation of Advanced Glycation End-products (AGEs); (2) directly blocking the RAGE-ligand interaction; (3) downregulating RAGE expression; and (4) suppressing downstream inflammatory signaling. Compounds like quercetin, ursolic acid, and berberine have demonstrated significant activity in various preclinical models. Natural products represent a profound source of multi-target RAGE modulators, offering a potential therapeutic advantage over synthetic single-target drugs. While challenges in bioavailability and clinical translation remain, the data strongly validates the ethnopharmacological approach. Future progress depends on integrating this traditional wisdom with modern technologies to unlock the full clinical potential of these compounds.\n\nID: 42400341\nTitle: ROS-Responsive Quercetin Nanoparticles Improve the Prognosis of Traumatic Brain Injury by Inhibiting Aberrant Nrf2-Keap1 Signaling Pathway Activation.\nAbstract: Traumatic brain injury (TBI) is one of the leading causes of mortality and disability worldwide, with secondary injury recognized as a critical therapeutic target. Quercetin (QR), a natural flavonoid, exerts antioxidant and anti-inflammatory effects by modulating the Nrf2-Keap1 pathway and shows neuroprotective potential in various neurological disorders. In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI, further highlighting the pivotal role of the Nrf2-Keap1 pathway in TBI treatment. However, the poor blood-brain barrier (BBB) permeability and low bioavailability of QR hinder effective brain-targeted delivery and limit its clinical translation. To address these challenges, we developed CAQK peptide-modified, reactive oxygen species (ROS)-responsive nanoparticles (C-PPS/Q), using PPS120 as the core for targeted QR delivery. C-PPS/Q exhibited ROS-triggered QR release, significantly enhanced HT22 cell uptake in\u00a0vitro, reduced ROS levels and apoptosis. In a TBI mouse model, C-PPS/Q specifically accumulated at the lesion site, prolonged the half-life of QR, demonstrated excellent biocompatibility, preserved BBB integrity, attenuated neuroinflammation, inhibited aberrant Nrf2-Keap1 pathway activation, and markedly improved neurological function. Collectively, C-PPS/Q nanoparticles effectively mitigate secondary brain injury after TBI and represent a promising brain-targeted therapeutic strategy for TBI management.\n\nID: 42399973\nTitle: A putative SGLT-relevant mechanistic perspective on quercetin-3-O-glucoside and rutin in diabetic kidney disease.\nAbstract: Type 2 diabetes mellitus (T2DM) is escalating worldwide and remains difficult to control durably, in part because progressive \u03b2-cell dysfunction undermines many therapies and because long-term management must balance efficacy, safety, and affordability. Recent decades have shown that targeting sodium-glucose cotransporters (SGLTs) especially renal SGLT2 can reduce glucose levels independently of insulin and, crucially, deliver cardio-renal benefits that extend beyond glycaemic control. Yet, despite the clinical success of synthetic \"gliflozins\", gaps remain, adverse events, incomplete inhibition of renal glucose reabsorption, and limited access in some health systems. This review focuses on two quercetin glycosides quercetin-3-O-glucoside (isoquercitrin) and quercetin-3-O-rutinoside (rutin) as potential SGLT-focused modulators. This study employed a narrative mechanistic review approach integrating published experimental evidence, physicochemical structure-activity relationship (SAR) analysis, and exploratory molecular docking to examine potential SGLT-related interactions and complementary glucose-regulatory pathways of Q3G and rutin. We synthesise mechanistic evidence suggesting that Q3G and rutin may modulate SGLT-related pathways through intestinal SGLT1 interaction, regulation of renal SGLT2 expression, and complementary glucose-regulatory mechanisms. However, direct inhibition of human SGLT2 transport activity has not yet been experimentally demonstrated, and current evidence predominantly may indicate indirect pathway modulation rather than gliflozin-like transporter inhibition. Contradictory findings across assay systems are discussed in relation to structure-activity relationships shaped by glycosylation. We further examine pharmacokinetics, tissue exposure plausibility, and translational feasibility, and propose a stepwise development roadmap emphasising transporter-specific assays, quantitative target engagement, and clinically meaningful biomarkers. Q3G and rutin may exhibit putative SGLT-relevant activity within a broader polypharmacological framework; however, direct transporter-specific inhibition and clinically relevant renal exposure remain to be established through future functional and translational studies.\n\nID: 42399921\nTitle: Degradable MMP9-responsive high-density lipoprotein nanoparticles enable efficient siRNA-PGRN and quercetin delivery to remodel the fibrotic microenvironment and attenuate renal fibrosis.\nAbstract: Renal fibrosis is the final common pathway of chronic kidney disease and remains a challenge due to the complex fibrotic and inflammatory microenvironment. This study aimed to develop an enzyme-responsive, fibrosis-targeted nanotherapeutic system capable of simultaneously delivering siRNA against progranulin (siPGRN) and quercetin (QT) to remodel the fibrotic microenvironment and effectively attenuate renal fibrosis. The TIMP-HDL-Nano@siPGRN&QT nanoparticles prepared in this study exhibit uniform nanoscale size (~\u2009100\u00a0nm), high encapsulation efficiency, excellent stability, and favorable biocompatibility. The MMP9-responsive modification significantly enhanced renal accumulation and fibrotic lesion targeting in vivo. Treatment with TIMP-HDL-Nano@siPGRN&QT markedly alleviated UUO-induced renal injury, apoptosis, and fibrosis, outperforming free drug. Transcriptomic and mechanistic analyses revealed that the therapeutic effects were mediated through disruption of the PGRN-PPAR\u03b1 interaction, restoration of PPAR\u03b1 signaling, and subsequent inhibition of NF-\u03baB-driven inflammatory pathways. Furthermore, the nanoparticles suppressed pro-inflammatory M1 macrophage polarization and promoted M2 polarization in a PPAR\u03b1-dependent manner. This study demonstrates that TIMP-HDL-Nano@siPGRN&QT enables efficient, targeted co-delivery of siRNA and small-molecule therapeutics to fibrotic kidneys. By remodeling the fibrotic immune microenvironment through the PGRN-PPAR\u03b1-NF-\u03baB axis, this nanoplatform provides a potent and mechanistically defined strategy for the treatment of renal fibrosis and offers translational potential for other inflammation-driven fibrotic diseases.\n\nID: 42398187\nTitle: Metabolomic insights into flavonoid migration and bioactivity enhancement in Apocynum venetum tea during hot-water brewing.\nAbstract: Apocynum venetum is a perennial shrub valued for its flavonoid-rich tea and medicinal properties. However, systematic evaluation of regional variation and hot-water brewing effects on flavonoid content and bioactivity remains limited. This study analyzed leaves from multiple regions as unprocessed tea (PT), brewed infusion (TS), and residues (TG) for flavonoid content, extraction efficiency, antioxidant activity, and metabolomic profiles. Shandong samples (P7, P6) exhibited higher total flavonoid contents (66.2, 68.6\u00a0mg/g) and extraction efficiencies (59.1%, 58.8%), with P7 exhibiting the strongest antioxidant activity. Metabolome analysis identified flavonoids as dominant metabolites, with phellodensin E enriched in infusions. KEGG enrichment revealed significant upregulation of quercetin-3-O-sulphate. In vivo bioactivity assays demonstrated that phellodensin E (20-25\u00a0\u03bcg/mL) and quercetin-3-O-sulphate (20\u00a0\u03bcg/mL) markedly reduced yolk-sac oxidative markers and neutrophil counts (P\u00a0<\u00a00.001), confirming strong antioxidant and anti-inflammatory effects. Overall, hot-water brewing provides a metabolomic basis for health-beneficial transformations in A. venetum tea.\n\nID: 42397024\nTitle: Camellia sinensis Silver Nanoparticles Inhibit Proliferation and Induce PARP-Dependent Apoptosis in A549 Cells: Formulation, Characterization, and Biological Evaluation.\nAbstract: In this work, the potential anti-cancer activity of silver nanoparticles (AgNPs-CS) prepared using Camellia sinensis, C. sinensis (CS) aqueous extract and its pro-apoptotic effects on human lung adenocarcinoma alveolar (A549) cells were investigated. AgNPs-CS were prepared by reduction of AgNO3 using C. sinensis aqueous extract, CSaq. Furthermore, they were characterized for their size, polydispersity index (PDI), \u03b6-potentials, morphology, and antioxidant activity. of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), acridine orange/ethidium bromide (AO/EB) staining, and Western blotting techniques were used to measure cell proliferation, apoptosis, and poly (ADP-ribose) polymerase, PARP cleavage. AgNPs-CS had a size, PDI and \u03b6-potential of 101\u2009nm, 0.12, and -21\u2009\u00b1\u20091.2\u2009mV, respectively. Furthermore, they are spherical with a core size of \u223c20-40\u2009nm and have significant antioxidant activity compared with quercetin. A sigmoidal dose-response curve exhibiting significant concentration-dependent reductions in cell viability was obtained. AgNPs-CS had an IC50 of 6.5 \u00b5g/ml and a significant level of apoptosis (\u223c57%) compared to CSaq and doxorubicin (Dox). Western blot analysis showed a higher level of cleaved PARP, with cPARP/\u03b2-actin ratios of 1.8 and 2.9 for CSaq and AgNPs-CS, respectively, confirmed the caspase-dependent apoptosis. AgNPs-CS is a promising green-based nanotherapeutic for treating lung cancer with an enhanced ability to kill cells and cause apoptosis in A549 cells.\n\nID: 42396042\nTitle: Electrosprayed Alginate-Fmoc Amino Acid Microcapsules for Quercetin Loading and Release.\nAbstract: This study presents the development of hybrid microcapsules for the loading and release of quercetin, produced by incorporation of Fmoc-Tyrosine (Fmoc-Y) or Fmoc-Proline (Fmoc-Pro) into alginate, followed by Ca2+-ion-mediated cross-linking. The microcapsules produced using this method were characterized in terms of particle size, morphology, chemical structure (FTIR), release behavior, and swelling properties. An average diameter of microcapsules loaded with quercetin was measured at 187 \u00b1 19 \u03bcm for Ca-Alginate, 154 \u00b1 14 \u03bcm for Ca-Alginate/Fmoc-Y, and 131 \u00b1 15 \u03bcm for Ca-Alginate/Fmoc-Pro. The inclusion of Fmoc-Pro or Fmoc-Y in the Ca-Alginate structure was shown by changes and shifts in the peak in FTIR. Rheological analyses revealed the flow behavior, viscoelastic properties, and shear-induced structural stability of alginate solutions used in microcapsule production. The incorporation of Fmoc-aa into alginate was intended to enhance the structural durability of the alginate matrix and thereby improve its drug release performance. Consistent with this expectation, examination of quercetin release at pH = 7.4 revealed that release from Ca-Alginate microcapsules was completed within 7 h, whereas release from the hybrid microcapsules extended to 24 h. Moreover, the zero-order model for Ca-Alginate microcapsules and the Korsmeyer-Peppas model for hybrid microcapsules were determined as the most appropriate mathematical models. The swelling behavior of the microcapsules was investigated at pH = 1.2 and 7.4. Although shrinkage occurred in the microcapsules at pH = 1.2, the spherical form was maintained in the first 7 h in hybrid and nonhybrid microcapsules. At pH = 7.4, it was observed that Ca-Alginate microcapsules were largely eroded approximately at the 6th hour, while hybrid Ca-Alginate/Fmoc-Y and Ca-Alginate/Fmoc-Pro microcapsules maintained their spherical form up to 16 h. These findings are supported by SEM analyses showing that hybrid microcapsules exhibit a more compact and less porous surface morphology compared to pure Ca-Alginate microcapsules.\n\nID: 42395946\nTitle: Quercetin Delivered by Mesenchymal Stem Cell-Derived Exosomes Improves Liver Fibrosis via the PI3K/Akt Signaling Pathway.\nAbstract: Liver fibrosis represents a critical stage in the progression of chronic liver diseases to cirrhosis and hepatocellular carcinoma; however, effective therapeutic options remain limited. Although quercetin, a natural flavonol, possesses potent antifibrotic properties, its clinical utility is severely hindered by poor aqueous solubility and low bioavailability. To address this limitation, we developed a nanoparticle-based drug delivery system using quercetin-loaded human umbilical cord mesenchymal stem cell (hUC-MSC)-derived exosomes (hUC-MSC-exo-Que). Leveraging the innate biocompatibility and targeting capability of exosomes, this strategy aims to improve the pharmacokinetic limitations of quercetin and amplify its therapeutic efficacy. Our results demonstrate that hUC-MSC-exo-Que significantly attenuates liver fibrosis in a carbon tetrachloride-induced mouse model, outperforming free quercetin at the equivalent dose. This enhanced efficacy is attributed to the superior inhibition of hepatic stellate cell activation, as confirmed by in vitro studies. The engineered exosomes exhibited a sustained drug release profile (up to 48 h) and maintained excellent stability for at least 1 week. Integrating network pharmacology with experimental validation, we identify the antifibrotic mechanism involving potent inhibition of the PI3K/Akt signaling pathway, with hUC-MSC-exo-Que achieving markedly greater pathway suppression than free quercetin. By successfully transforming a potent but poorly bioavailable phytochemical into a targeted nanotherapeutic, we present a promising preclinical strategy for liver fibrosis treatment and demonstrate a proof-of-concept platform for hydrophobic drug delivery.\n\nID: 42395344\nTitle: Deciphering MMRN1 diagnostic and therapeutic implications in the substantia nigra of Parkinson's disease patients via integrative bioinformatic analysis and multi-omics studies.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra (SN), primarily due to \u03b1-synuclein aggregation, posing a major health threat to the elderly population. Current treatment options remain limited, necessitating the discovery of novel diagnostic and therapeutic targets. This study aimed to identify a novel diagnostic and druggable target in the SN of PD patients. We first nominated PD risk-associated differentially expressed genes (DEGs) in the SN bulk profile (GSE7621) of PD patients using Limma, weighted gene co-expression network analysis (WGCNA), and summary-data-based Mendelian randomization (SMR). Next, three machine learning algorithms [random forest (RF), least absolute shrinkage and selection operator LASSO, and support vector machine (SVM)] were performed for the identification of central pathogenic factors among the risk DEGs in the training PD patient SN bulk profile (integrated GSE20163 and GSE20164). In addition, the diagnostic performance of the identified central pathogenic factor for PD was evaluated in GSE7621, integrated GSE20163 and GSE20164, and independent PD patient SN bulk profiles (GSE140231). In addition, the molecular and immune patterns of the central pathogenic factor were assessed in SN single-cell data from PD patients (GSE7621) were estimated by a cutting-edge analytical framework in temporal and spatial manners. Furthermore, network-based drug screening and molecular docking were subsequently performed to identify potential therapeutic agents targeting the central pathogenic factors. Finally, in vitro assays estimated the expression patterns of the central pathogenic factor. Multimerin 1 (MMRN1) was identified as an upregulated pathogenic factor predominantly expressed in neurons. Quercetin was highlighted as a promising repurposed drug candidate targeting MMRN1. This study illustrated a novel diagnostic and therapeutic target for PD, which provides novel clues into clinical applications of PD patients.\n\nID: 42394678\nTitle: A study on the dynamic differences and component correlations of astringency in green tea, black tea and oolong tea based on TI/TDS and LC-MS.\nAbstract: The dynamic patterns and chemical drivers of astringency across tea varieties remain underexplored. This study integrated time-intensity (TI), temporal dominance of sensations (TDS), electronic tongue, and LC-MS analyses to evaluate astringency in six green, black, and oolong teas. TI results indicated that green tea exhibited higher peak intensity, larger area under the curve (AUC), longer duration, and faster onset compared to oolong and black teas. TDS analysis revealed dominant sensations: \"harsh\" and \"coarse grain\" for green tea, \"smooth\" and \"dry\" for black tea, and alternating \"rough\" and \"dry\" for oolong tea. LC-MS profiling linked high astringency to anthocyanins, quercetin derivatives, and catechin oxidation products. Roughness correlated with polymerized catechins, granularity with flavanols, and dryness with oxidized polyphenols. Overall, polyphenol type and structure are key determinants of astringency intensity and sub-quality variations among tea types.\n\nID: 42394568\nTitle: A simple, sensitive microsample LC-MS assay for quercetin and isorhamnetin in mouse and human plasma: application to EMIQ treatment in myotonic dystrophy type 1.\nAbstract: Quercetin, a dietary flavonoid with emerging therapeutic relevance in myotonic dystrophy type 1 (DM1), has low solubility and poor oral bioavailability. Enzymatically modified isoquercitrin (EMIQ), a water-soluble prodrug, raises systemic quercetin exposure. Pharmacokinetic studies require a sensitive assay that uses minimal sample volume. We developed a single-quadrupole liquid chromatography-mass spectrometry (LC-MS) assay for free quercetin, total quercetin (after enzymatic hydrolysis of glucuronide and sulfate conjugates), and the methylated metabolite isorhamnetin in mouse and human plasma. The method used protein precipitation, 10\u2009\u00b5L of plasma, reversed-phase C18 separation, and single-ion recording of [M+H]+ adducts. Validation followed a fit-for-purpose approach consistent with M10 guidelines, and the assay was applied to plasma from EMIQ-treated DM1 and wild-type mice (15\u2009g/L for 6 and 12\u2009weeks). Calibration curves showed r2\u2009 > 0.99, with an LLOQ of 0.070\u2009\u00b5M for quercetin in both matrices. The assay was successfully validated for quercetin in mouse and human plasma. Total quercetin and isorhamnetin were quantifiable in all treated mice. Exploratory analysis suggested glucuronidation as the major conjugation pathway. This simple, cost-effective microsampling assay suits preclinical and translational studies of EMIQ in DM1, though the conjugation findings remain exploratory. Quercetin is a natural compound found in many foods that researchers are studying as a possible treatment for myotonic dystrophy type 1 (DM1), an inherited muscle disease. A problem is that the body absorbs quercetin poorly, so a more soluble form called EMIQ is used to raise its levels in the blood. To study how much quercetin reaches the blood, scientists need a reliable way to measure it, but the levels are often very low and usually require costly equipment and large blood samples. We developed a simpler, inexpensive laboratory method that measures quercetin and a related substance, isorhamnetin, using only a tiny blood sample, about one drop. The method worked reliably in both mouse and human blood. We then used it to measure quercetin in mice given EMIQ, including a mouse model of DM1, and could detect the compound in all treated animals. Because the test needs only a small sample, it reduces the number of animals needed for research and could make future human studies easier.\n\nID: 42392795\nTitle: [Research progress on intervention of active components of Bupleuri Radix in metabolic dysfunction-associated fatty liver disease based on multiple parallel strike theory].\nAbstract: Metabolic dysfunction-associated fatty liver disease(MAFLD) is a prevalent chronic liver disease worldwide. Due to its complex pathogenesis, there is currently no specific drug capable of intervening throughout the entire pathological process, nor a unified and definitive treatment protocol in clinical practice. In traditional Chinese medicine, MAFLD falls under the category of diseases such as "hypochondriac pain" and "liver disease", with the core pathogenesis being "stagnation of the liver meridian and obstruction of Qi movement". The pharmacological characteristics of Bupleuri Radix(BR), which "soothes the liver, relieves stagnation, and promotes Qi movement", are highly consistent with this pathogenesis. Furthermore, data mining studies have shown that BR is among the most frequently used herbs in TCM clinical protocols for treating MAFLD, and its herb pairs and classic formulas have demonstrated favorable therapeutic effects in clinical application. Modern pharmacological studies have also confirmed that BR is rich in active ingredients, including saponins(e.g., saikosaponin A/D/B2), volatile oils(e.g., D-limonene, hexanoic acid), flavonoids(e.g., quercetin, rutin, kaempferol), and polysaccharides. These active ingredients can target multiple pathological aspects of the "multiple parallel hits" in MAFLD, such as improving insulin resistance(IR), alleviating endoplasmic reticulum stress(ERS), repairing mitochondrial function, regulating oxidative stress(OS) response, modulating intestinal microbiota imbalance, and inhibiting inflammasome activation, thereby slowing the progress of MAFLD. Its mechanism of action is closely related to the regulation of PI3K/Akt, PPAR, Nrf2, AMPK, MAPK, PINK1/Parkin, NLRP3 inflammasome and the "gut-liver axis", reflecting the integrative regulatory advantages of TCM's multi-component, multi-target and multi-mechanism approach. Future in-depth studies should focus on precise component profiling of BR, validation of key targets, and the synergistic mechanisms within "formula-component" interactions to better leverage the value of BR in the prevention and treatment of MAFLD.\n\nID: 42392719\nTitle: [Quercetin improves cognitive impairment in mice with Alzheimer's disease by inhibiting inflammatory response and activating cAMP/PKA/CREB signaling pathway].\nAbstract: This study aimed to investigate the effects of quercetin on cognitive dysfunction in a mouse model of Alzheimer's disease(AD) and to explore its potential mechanisms. Network pharmacology was used to construct a "drug-core component-key target-pathways-disease" network to identify potential targets and related pathways associated with drug efficacy. Thirty 3-month-old male APP/PS1 transgenic mice were randomly divided into a model group, a quercetin group(100 mg\u00b7kg~(-1)), and a donepezil hydrochloride group(0.5 mg\u00b7kg~(-1)), while age-matched C57BL/6J mice from the same litter served as the control group. Each group consisted of 10 mice, and the treatment groups received the corresponding drug interventions for 24 weeks. The Morris water maze(MWM) test was used to assess memory performance, and the nest-building test was applied to evaluate daily living ability. hematoxylin-eosin(HE) staining, Nissl staining, and immunohistochemistry were used to assess pathological changes in hippocampal neurons. Western blot analysis was used to detect the expression levels of tau, phosphorylated(p)-tau, interleukin-1\u03b2(IL-1\u03b2), tumor necrosis factor-\u03b1(TNF-\u03b1), brain-derived neurotrophic factor(BDNF), cyclic adenosine monophosphate(cAMP), protein kinase A(PKA), p-PKA, cAMP response element-binding protein(CREB), and p-CREB-related signaling proteins in hippocampal tissue. Network pharmacology analysis identified 165 quercetin-related active component targets and 4 324 learning-and memory-related targets. Intersection analysis yielded 71 AD-related core genes. Protein-protein interaction(PPI) network analysis identified protein kinase B(Akt1), estrogen receptor 1(ESR1), epidermal growth factor receptor(EGFR), and non-receptor tyrosine kinase(SRC) as core target genes. Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis indicated that quercetin may regulate AD progression through the PI3K/Akt signaling pathway, cAMP signaling pathway, TNF signaling pathway, and EGFR tyrosine kinase inhibitor resistance-related pathways. Animal experiments showed that, compared with the control group, the model group exhibited significantly reduced nesting scores, prolonged escape latency(P<0.05), and fewer platform crossings(P<0.05). The number of neurons in the cortex and hippocampus was significantly decreased, and extracellular amyloid \u03b2(A\u03b2) deposition was significantly increased(P<0.01). In addition, the expression levels of p-tau/tau, IL-1\u03b2, TNF-\u03b1, cAMP, p-PKA/PKA, and p-CREB/CREB in hippocampal tissue were significantly elevated(P<0.01), whereas BDNF protein expression was significantly reduced(P<0.01). Compared with the model group, the quercetin and donepezil hydrochloride groups showed significantly increased nesting scores, shortened escape latency(P<0.05), and increased numbers of platform crossings(P<0.05). The number of neurons in the hippocampal CA1 region was significantly increased(P<0.01), and the expression levels of p-tau/tau, IL-1\u03b2, TNF-\u03b1, cAMP, p-PKA/PKA, and p-CREB/CREB in hippocampal tissue were significantly decreased(P<0.05, P<0.01). These results indicate that quercetin can significantly improve cognitive impairment in APP/PS1 transgenic mice, and its mechanism may be associated with activation of the cAMP/PKA/CREB signaling pathway and reversal of the upregulation of pro-inflammatory cytokines, including TNF-\u03b1 and IL-1\u03b2.\n\nID: 42392709\nTitle: [Effects of different fermentation conditions on microbial community and chemical composition of Huafengdan Yaomu].\nAbstract: To investigate the effects of different fermentation conditions on the microbial community structure and chemical composition of Huafengdan Yaomu, this study compared the physicochemical properties, microbial composition, and chemical composition under fermentation with controlled temperature and humidity with those under natural fermentation. The results show the darkening of Yaomu color, significant pH changes, and decreases in the contents of total alkaloids and total flavonoids after fermentation(P<0.05). Microbial community analysis reveals that the number of bacterial amplicon sequence variants(ASVs), abundance, and diversity are significantly increased under fermentation with controlled temperature and humidity, with dominant genera including Ligilactobacillus, Levilactobacillus, and Pichia. In contrast, the natural fermentation group is dominated by Levilactobacillus, Lactiplantibacillus, and Pichia. 584 differential components are screened from 3 003 compounds by metabolomic analysis, including 40 alkaloids and 31 flavonoids. The fermentation group with controlled temperature and humidity exhibits the highest number of differential compositions, with the number of 25 alkaloids including hydropeimine and deltaline significantly increasing, 15 alkaloids including neoline significantly decreasing, 18 flavonoids including loquatoside increasing, and 13 flavonoids including kaempferol decreasing. Natural fermentation is conducive to the production of flavonoid compositions such as kaempferol and quercetin, whereas its effect on reducing toxic alkaloids is less pronounced compared to the fermentation with controlled temperature and humidity. Correlation analysis further indicates that alkaloid compositions are positively correlated with bacterial genera such as Lactiplantibacillus, while flavonoid compositions are positively correlated with fungal genera such as Wickerhamomyces. In conclusion, fermentation conditions significantly affect the chemical composition of Yaomu by regulating the microbial community structure. Fermentation with controlled temperature and humidity demonstrates greater advantages in reducing toxic components, providing a scientific basis for optimizing traditional fermentation processes and improving the quality control of TCM.\n\nID: 42392409\nTitle: Macrophage Senescence and Programmed Cell Death in Atherosclerosis: Mechanisms, Cross-Talk, and Emerging Therapeutic Strategies.\nAbstract: Atherosclerosis imposes a heavy burden on global healthcare systems and remains the leading cause of mortality worldwide, with macrophage dysfunction playing a critical role in its pathogenesis. This review examines the dual roles of macrophage senescence and programmed cell death (PCD) in the progression of atherosclerosis, highlighting their mechanisms, cross-talk and emerging therapeutic strategies. Macrophage senescence-characterized by irreversible cell cycle arrest, mitochondrial dysfunction, and the senescence-associated secretory phenotype (SASP)-exacerbates chronic inflammation and impairs tissue repair. Meanwhile, PCD pathways, including apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagy, regulate inflammatory responses and cellular homeostasis; however, their dysregulation accelerates arterial pathology. Shared molecular pathways such as NF-\u03baB, mTOR, and p53 govern both processes, while distinct features define their respective contributions: senescence reflects cumulative damage and functional decline, whereas PCD involves regulated, context-dependent cellular demise. In atherosclerosis, senescent macrophages promote plaque instability through SASP-driven inflammation and impaired efferocytosis, while PCD modalities such as necroptosis and pyroptosis exacerbate necrotic core formation. Emerging therapeutic strategies targeting these pathways-including senolytics, NLRP3 inhibitors, ferroptosis suppressors, and autophagy enhancers-show promise in preclinical models by mitigating inflammation, restoring macrophage function, and stabilizing plaques. Pharmacological interventions such as quercetin (a p38 MAPK inhibitor), melatonin (an Nrf2 activator), and senolytic agents illustrate the potential to disrupt the senescence-PCD axis. This synthesis underscores the importance of delineating context-specific roles of macrophage senescence and PCD in atherosclerosis, offering a roadmap for dual-targeted therapies to alleviate cardiovascular burden. By integrating mechanistic insights with translational applications, this review identifies novel biomarkers and therapeutic avenues to combat aging-related atherosclerotic pathologies.\n\nID: 42391292\nTitle: Morpho-biochemical diversity and phytochemical profiling of Rubus fruticosus L. landraces.\nAbstract: The flora of Khyber Pakhtunkhwa, Pakistan, is severely threatened by illegal harvesting of non-timber forest resources, resulting in the genetic loss of native plant species, including Rubus fruticosus L., a genetically diverse shrub of considerable economic and medicinal importance. The present study was designed to assess the morphological diversity, seed protein profiles, and phytochemical composition of fifteen landraces of R. fruticosus collected from different ecological zones of the Malakand Division, Khyber Pakhtunkhwa, Pakistan. Morphological characteristics were evaluated using the International Board for Plant Genetic Resources (IBPGR) descriptors, incorporating both qualitative and quantitative traits in a randomized complete block design. Seed protein diversity was assessed through sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), while phytochemical composition was quantified using high-performance liquid chromatography with ultraviolet detection (HPLC-UV). Morphological traits exhibited significant variability, with a mean coefficient of variation (CV) of 36.72%. The most variable traits were single fruit weight (CV\u2009=\u200973.16%), five-fruit weight (CV\u2009=\u200964.38%), number of branches per plant (CV\u2009=\u200933.33%), plant height (CV\u2009=\u200931.31%), and stalk length (CV\u2009=\u200930.11%). Principal component analysis (PCA) explained 89.71% of the total variation, with plant height, leaflet number, and fruit weight contributing predominantly to landrace differentiation. SDS-PAGE analysis of seed proteins revealed 21 polymorphic bands (molecular weight range: 14.4-97.4 kDa), with high diversity indices recorded for markers B-03, B-06, B-08, B-12, and B-21 (Shannon diversity index H'\u2009=\u20091.10-1.39; CV\u2009=\u200935.36-93.54%). HPLC-UV analysis identified twelve phenolic compounds in selected genotypes, including quercetin (5.12-8.74 \u00b5g/mL), morin (3.45-6.89 \u00b5g/mL), and epigallocatechin gallate (2.88-7.23 \u00b5g/mL). The morphological, biochemical, and phytochemical diversity observed among R. fruticosus landraces highlights their potential for conservation programs and future breeding initiatives.\n\nID: 42389891\nTitle: Identification of PRKCB, NLRC4, and TNFSF10 as Key Regulators of the Lipid Metabolism-Autophagy Network in Atherosclerosis.\nAbstract: The occurrence and development of atherosclerosis (AS) are closely related to disorders of lipid metabolism and dysfunction of autophagy. However, the key regulatory genes and immune microenvironment characteristics require further exploration. This study integrated the bulk transcriptome and single-cell RNA sequencing data, and utilized bioinformatics methods to screen the differentially expressed genes (DEGs) of AS. The weighted gene co-expression network analysis (WGCNA) was used to identify the key gene modules related to lipid metabolism and autophagy. The core regulatory genes were further screened based on the machine learning algorithm (LASSO regression). The enrichment scores of 28 immune cell subtypes were calculated by ssGSEA, and the correlation between the immune infiltration characteristics and the expression levels of the three core genes (PRKCB, NLRC4, and TNFSF10) was analyzed by Spearman correlation analysis. The single-cell transcriptome data analysis was performed to determine the cell subtype distribution characteristics of the core genes and to compare the expression differences in lipid metabolism-autophagy-related gene expression across distinct cell subtypes. In addition, we screened potential drugs targeting the key genes from the public drug database, and simulated the binding mode of approved drugs with the active site of PRKCB by molecular docking technology. Ultimately, the expression of target factors in mouse aortic tissues was determined by quantitative real-time PCR (RT-qPCR), Western blotting, and immunohistochemical (IHC) analysis. Concurrently, the levels of TNFSF10 in mouse plasma were confirmed through enzyme-linked immunosorbent assay (ELISA). Three lipid metabolism-autophagy core regulatory genes, PRKCB, NLRC4, and TNFSF10, were identified. These genes were significantly associated with the immune microenvironment of AS plaques and exhibited different cell subpopulation distribution patterns. The macrophage subpopulations showed higher lipid metabolism-autophagy regulatory activity. Molecular docking revealed that the anti-atherosclerotic drugs quercetin and atenolol can stably bind to the active site of PRKCB (with docking energies of -8.3\u2009kcal/mol and -6.2\u2009kcal/mol, respectively), a finding that identifies PRKCB as a candidate target worthy of further attention. Experimental evidence confirmed that the expression of these three key factors was significantly elevated in atherosclerotic plaque tissue, and the levels of TNFSF10 in the plasma of atherosclerotic mice were also significantly higher than those in the control group. This study identifies PRKCB, NLRC4, and TNFSF10 as key hub genes that link lipid metabolism and autophagy in AS, and highlights their potential as diagnostic biomarkers and therapeutic targets.\n\nID: 42389727\nTitle: Network pharmacology-guided identification of kinase-mediated vascular signalling targets underlying the antihypertensive potential of Brassica rapa L.\nAbstract: Hypertension is a complex cardiometabolic disorder involving oxidative stress, endothelial dysfunction, inflammation, and neurohormonal imbalance, which increases vascular resistance and remodeling. Consequently, single-target treatment frequently has low long-term efficacy. Brassica rapa L. (BRL) turnip, a medicinal and dietary crucifer rich in glucosinolates, flavonoids, and phenolic acids, offers significant potential for blood pressure modulation. Using a comprehensive in silico approach that combines network pharmacology, molecular docking, molecular dynamics simulation, and ADMET-guided screening, this study examines the multitarget antihypertensive potential of BRL. In the list of 189 phytoconstituents identified from extensive databases, 9 drug-like candidates were ultimately selected using SwissADME profiling and Lipinski's rule of 5. Predicted protein targets identified through SwissTargetPrediction and the similarity ensemble approach were cross-referenced with hypertension-associated genes from GeneCards and online Mendelian Inheritance in Man, yielding 246 common targets. Protein-protein interaction analysis identified an essential component comprising 10 hub genes, including EGFR, PIK3CA, FYN, PTK2, SRC, PTPN11, PIK3R1, CTNNB1, and AKT1, indicating a critical role for kinase-driven vascular signalling. The functional enrichment analysis identified redox homeostasis, vascular regulatory balance, and the PI3K-AKT and nitric/eNOS signalling pathways. AutoDock Vina docking identified quercetin (-\u200911.4\u00a0kcal/mol), kaempferol and isorhamnetin (-\u200911.2\u00a0kcal/mol), gluconasturtiin (-\u200911.2\u00a0kcal/mol) as top ligands. Schrodinger molecular dynamics simulations over 100\u00a0ns confirmed the stability and energetically favorable nature of the protein-ligand interactions. Overall, BRL demonstrates strong multitarget antihypertensive potential, with prioritized lead molecules for further validation.

Therefore, an ovalbumin (OVA)-induced AR mouse model was established to investigate whether quercetin can treat AR by regulating the TLR4/MyD88/IRAK4 signaling pathway. OVA and aluminum hydroxide were injected intraperitoneally for sensitization, and OVA was dripped into the nose to establish a mouse model of AR. The mice were scored on behaviors such as scratching, sneezing and a runny nose to assess the success of the modeling. The treatment groups were given the relevant drugs (dexamethasone and quercetin) by gavage for 1 week after successful modeling. Following the completion of treatment, the serum OVA-IgE, IL-4, IL-13, IL-1\u03b2, IL-17 and IL-10 levels were measured; changes in the nasal mucosa were observed; protein and mRNA expression levels of TLR4, MyD88, IRAK4 and NF-\u03baB in lung tissue were determined; and changes in the percentages of regulatory T cells (Tregs) and T helper 17 (Th17) cells in the spleen were assessed. The results showed that compared with the normal control (NC) group, the allergic symptom scores were >10 points, and the serum levels of OVA-IgE, IL-4, IL-13, IL-1\u03b2 and IL-17 increased, whereas the serum level of IL-10 decreased in the OVA group. Detachment and necrosis of the nasal mucosa, accompanied by tissue edema and inflammatory cell infiltration, were observed in the OVA group. Compared with the NC group, the relative expression mRNA and protein levels of TLR4, MyD88, IRAK4 and NF-\u03baB in lung tissues increased, the percentage of Tregs decreased and the percentage of Th17 cells increased in splenocytes of the OVA group. Based on these results, it was hypothesized that quercetin inhibits inflammatory responses and induces immune tolerance by regulating the TLR4/MyD88/IRAK4 signaling pathway in a mouse model of AR.\n\nID: 42389449\nTitle: Ginkgo biloba extract 50 dropping pills improve vascular cognitive impairment through anti-oxidative and anti-inflammatory effects.\nAbstract: The aim of the present study was to investigate the improvement effect of Ginkgo biloba extract 50 dropping pill (GBE50DP) on vascular cognitive impairment (VCI) induced by cerebral ischemia and its mechanism. The VCI rat model was established by 2-vessel occlusion and randomly divided into the control, model, positive and GBE50DP administration groups. The administration groups were then administered GBE50DP intragastrically for 8 weeks. The social behavior and ability of learning and memory of each group were tested through the Morris water maze and eight-arm maze experiment. The content of oxidative stress and inflammatory factors in the hippocampus of rats were detected using ELISA. Hematoxylin & eosin staining and Terminal-deoxynucleotidyl transferase mediated nick end labeling staining were used to observe the morphological changes of nerve cells in the hippocampal CA1 region of rats. The expression of Caspase-3, Bcl-2, Bax, cytochrome c (Cyto-C), fibroblast-associated antigen (Fas) and poly(ADP-ribose) polymerase-1 (PARP-1) proteins in the hippocampal CA1 region of rats was detected by immunohistochemistry and western blot analysis. The blood components of GBE50DP were analyzed using liquid chromatography-tandem mass spectrometry. The model rats showed significant cognitive impairment; compared with the model group, in the GBE50DP administration groups, the social behavior of rats was markedly improved; the content of superoxide dismutase, glutathione peroxidase and catalase in the hippocampus was markedly increased and that of malondialdehyde, IL-1\u03b2, IL-6 and TNF-\u03b1 was significantly decreased. The pathological changes and expression of Cyto-C, Bax, Bcl-2, Caspase-3, Fas and PARP-1 proteins in brain tissue were markedly improved. The index components of GBE50DP in blood included ginkgolide A, B, C and K and bilobalide, as well as flavonoids such as rutin and quercetin. In conclusion, GBE50DP improved the social behavior, ability of learning and memory in VCI rats, decreased nerve cell damage and protected nerve cells from apoptosis by reducing oxidative stress and inflammation, thereby improving cognitive dysfunction.\n\nID: 42386771\nTitle: Multi-omics profiling reveals systemic rejuvenation of the aged kidney through senolytic therapy.\nAbstract: Cellular senescence is a key driver of kidney aging, leading to functional decline and increased susceptibility to chronic kidney disease. While the senolytic combination of dasatinib and quercetin (D\u2009+\u2009Q) has shown promise in mitigating age-related pathologies, its long-term effects and underlying multi-level systemic mechanisms in the aging kidney remain poorly defined. Here, we systematically evaluated the long-term effects of D\u2009+\u2009Q in naturally aged mice using multi-omics approaches. We show that D\u2009+\u2009Q treatment reduces senescence markers (p16, p21, SA-\u03b2-gal), restores the anti-aging protein Klotho, and attenuates renal fibrosis and inflammation. Proteomic profiling reveals that D\u2009+\u2009Q enhances apoptotic clearance of senescent cells and promotes proliferative and regenerative pathways. Moreover, D\u2009+\u2009Q reactivates PPAR\u03b1 signaling, improves fatty acid oxidation, and reduces lipid accumulation in aged kidneys. Single-cell transcriptomics further demonstrates that D\u2009+\u2009Q reverses transcriptional aging signatures across multiple renal cell types and remodels cell-type-specific pathways associated with metabolism, inflammation, and fibrosis. Cell-cell communication analysis reveals that D\u2009+\u2009Q normalizes the hyperconnected intercellular network in aged kidneys, particularly by modulating inflammation-related signaling. Our findings offer a comprehensive, systems-level understanding of how senolytic therapy restores renal homeostasis, emphasizing its potential as a multifaceted intervention to combat kidney aging.\n\nID: 42386090\nTitle: Ethnopharmacological validation of the antinociceptive potential of Calotropis gigantea L. flowers: Phytochemical characterization, safety evaluation, and mechanistic insights from in vivo models.\nAbstract: Calotropis gigantea L. is traditionally used in South and Southeast Asia for the management of pain, inflammation, cough, burns, and other disorders. However, scientific evidence supporting its traditional use in pain management remains limited. The present study aimed to evaluate the antinociceptive activity, safety profile, phytochemical composition, and possible mechanisms underlying the antinociceptive effects of the ethanolic extract of flowers of C. gigantea (CGEE). Phytochemical profiling was performed using qualitative screening, total phenolic and flavonoid assays, DPPH radical scavenging assay, and HPLC analysis. Acute and subacute oral toxicity studies were conducted according to OECD guidelines 423 and 407, respectively. Antinociceptive activity was evaluated using hot plate, tail flick, formalin-induced paw licking, and acetic acid-induced writhing models in rats. Mechanistic investigations were carried out using Nalbin, Atropine, Glibenclamide, and Terazosin to assess the involvement of opioidergic, cholinergic, KATP channel, and noradrenergic pathways respectively. Phytochemical screening revealed the presence of phenolics, flavonoids, alkaloids, glycosides, tannins, saponins, amino acids, and reducing sugars. HPLC analysis identified chlorogenic acid, quercetin, gallic acid, syringic acid, vanillic acid, and coumaric acid derivatives. The extract exhibited considerable DPPH free radical scavenging activity with an IC50 value of 145.77\u202f\u00b1\u202f4.30\u202f\u03bcg/mL. In addition, the extract contained high levels of phenolic and flavonoid constituents, with total phenolic content of 98.35\u202f\u00b1\u202f3.12\u202fmg gallic acid equivalents (GAE)/g extract and total flavonoid content of 65.20\u202f\u00b1\u202f2.45\u202fmg catechin equivalents (CE)/g extract. Acute and subacute toxicity studies showed no mortality or significant toxicological alterations. CGEE produced significant (p\u202f<\u202f0.05) dose-dependent mg/kg. Mechanistic studies demonstrated the involvement of opioidergic, cholinergic, ATP-sensitive K+ channel, and noradrenergic pathways. The findings provide pharmacological evidence supporting the traditional use of C. gigantea in pain management. The antinociceptive effects may be associated with the synergistic action of phenolic and flavonoid constituents through modulation of multiple nociceptive pathways. CGEE also demonstrated a favorable safety profile, supporting its potential as a source of novel antinociceptive agents.\n\nID: 42385849\nTitle: Quercetin and Carvacrol Act Synergistically to Inhibit Candida albicans Biofilms In Vitro via Membrane Disruption and Oxidative Stress.\nAbstract: Candida albicans biofilms are a major cause of device-associated infections and treatment failure due to high antifungal tolerance. Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation. Findings are preliminary and limited to in vitro assays; in vivo efficacy and safety remain to be established.\n\nID: 42385623\nTitle: Fresh and freeze-dried pulp of Eugenia gracillima Kiaersk. (Myrtaceae): Composition and thermostability of an unconventional edible Brazilian fruit.\nAbstract: The present study aimed to characterize the fresh pulp of E. gracillima Kiaersk. fruits and to evaluate its stability following freeze-drying. The characterization included sugar profiling by High-Performance Liquid Chromatography Coupled to Mass Spectrometry, mineral composition analysis by Microwave Plasma-Atomic Emission Spectroscopy, and untargeted metabolomic profiling using Ultra-High Performance Liquid Chromatography coupled to Quadrupole Time-of-Flight Mass Spectrometry, in addition to thermal studies performed by thermogravimetry (TG), derivative TG (DTG), and Differential Scanning Calorimetry. Results revealed a predominance of fructose, calcium and magnesium as the main minerals detected, and the putative annotation of phenolic acids, flavonols, flavones, and anthocyanins, with quercetin-7-glucoside and delphinidin-3-glucoside among the annotated flavonoids. E. gracillima Kiaersk. can be considered an underutilized fruit with high-quality pulp composition and promising technological attributes. Furthermore, the freeze-dried fruit exhibited improved thermal stability, withstanding temperatures up to approximately 200\u00a0\u00b0C, thus, revealing great advantages and applications for industries and the consumer market.\n\nID: 42385613\nTitle: Analysis of the component basis for anti-fatigue active ingredients in fermented black mulberry juice based on the C2C12 cell model and LC-MS.\nAbstract: This study aimed to investigate the anti-fatigue activity of fermented black mulberry juice and elucidate its component basis. A fatigue model was established using C2C12 mouse myoblasts induced by using a combined treatment of H2O2 induction and electrical stimulation. The ethyl acetate, butan-1-ol, and water extracts enhanced cell viability and mitochondrial membrane potential while reducing lactate dehydrogenase and reactive oxygen species levels. RT-qPCR indicated these extracts promote mitochondrial biogenesis, with ethyl acetate extract showing the most significant effect. Compositional analysis via liquid chromatography-mass spectrometry revealed that the ethyl acetate extract primarily contained phenolic acids such as caffeic acid, while the butan-1-ol fraction was rich in flavonoids including rutin and quercetin. Although the water extract shared a similar compositional profile, its antioxidant activity was lower due to insufficient levels of characteristic active substances. The butan-1-ol extract exhibited the highest chemical richness, with 2972 compounds tentatively identified.\n\nID: 42407188\nTitle: Natural-product polypharmacology in acute lymphoblastic leukemia: a state-of-the-art review.\nAbstract: High-risk and relapsed/refractory (R/R) acute lymphoblastic leukemia poses significant therapeutic challenges due to emergent drug resistance and dose-limiting toxicities. Natural products, with their diverse chemical structures and pharmacological activities, provide a promising avenue for multi-target therapies. This review analyzes key natural product classes, such as phenolic compounds, terpenoids, flavonoids, and alkaloids. It aims to elucidate their mechanisms by modulating critical oncogenic pathways to overcome drug resistance, paving the way for rational therapeutic design strategies. A comprehensive literature review was conducted by systematically searching Web of Science, PubMed, and Google Scholar. Search queries combined \"acute lymphoblastic leukemia\" with various natural product classes, focusing on publications from 2000 to 2025. The analysis synthesized data on molecular mechanisms, pharmacokinetics, safety, and synergistic strategies for combination therapy. The database search yielded 303,464 hits, with 13,839 hits from Web of Science, 14,625 hits from PubMed, and 275,000 hits from Google Scholar. After removal of duplicates, commentary articles, clearly ineligible literature, and records not within the predefined topic range were removed, 280 records were screened. 73 publications were assessed for eligibility, and 53 studies were included in the final synthesis. The studies considered in this review largely focused on chemically characterized natural products and derivatives comprising phenolic compounds, terpenoids, flavonoids, alkaloids, and artemisinin-related compounds. Most evidence was collected from preclinical ALL models and involved modulation of apoptosis, oxidative stress, cell-cycle arrest, autophagy, ferroptosis, and ALL-related signaling pathways. In conclusion, these natural products showed multi-target and pathway-intersecting activities that could improve conventional anti-leukemic treatment and overcome chemoresistance, although clinical translation remains limited by insufficient in vivo validation, insufficient PK/PD characterization, poor bioavailability, and incomplete safety evaluation. Natural products offer a valuable resource for developing novel anti-ALL therapeutics. Their multi-target capability fosters synergistic combinations to combat resistance, highlighting the need for advanced technologies and precision medicine approaches in ALL treatment.\n\nID: 42407178\nTitle: Macrophage autophagy in allergic diseases: Regulatory mechanisms, immune crosstalk, and therapeutic implications.\nAbstract: Macrophages are pivotal effector cells within the innate immune system, playing a central role in inflammation regulation, tissue homeostasis, and immune defense. Recent studies have demonstrated that macrophage autophagy-a highly conserved process essential for cellular homeostasis-plays a critical role in dynamically balancing immune responses by selectively eliminating damaged organelles, pathogens, and protein aggregates. Macrophage autophagy is finely regulated by various signaling pathways, such as mTOR and NF-\u03baB, and its dysfunction is closely associated with the onset and progression of allergic diseases. This review systematically synthesizes the molecular mechanisms governing macrophage autophagy and its dual role in allergic diseases, including allergic rhinitis, asthma, and atopic dermatitis. It highlights the functions of key signaling pathways (e.g., mTOR, NF-\u03baB) and regulatory factors (e.g., p62, Beclin-1, LC3) and explores the crosstalk between macrophage autophagy, immunometabolism, and cellular polarization. Explores the crosstalk between macrophage autophagy, immunometabolism, and cellular polarization, and further elaborates the reciprocal regulatory network of autophagy and metabolic reprogramming within allergic inflammatory microenvironment. Furthermore, the review summarizes potential therapeutic strategies targeting macrophage autophagy, such as budesonide/simvastatin combination therapy and rapamycin derivatives, along with their clinical translation prospects, with the aim of providing a theoretical foundation for developing novel, autophagy-targeted precision therapies for allergic diseases.\n\nID: 42407106\nTitle: Therapeutic strategies of traditional Chinese medicine for chronic heart failure: from active ingredients to herbal formulations.\nAbstract: Chronic heart failure (CHF) remains a global health challenge with complex pathological mechanisms, including inflammation, oxidative stress, mitochondrial dysfunction, myocardial remodeling, ferroptosis, and autophagy. Despite some progress in modern medicine for the treatment of CHF, challenges remain, including insufficient therapeutic efficacy and significant side effects. In this context, traditional Chinese medicine (TCM), characterized by its multi-component, multi-target, and holistic regulatory properties, demonstrates potential advantages in the prevention and treatment of CHF. This paper summarizes the research progress of active ingredients from Chinese medicinal herbs, single herbs, and traditional Chinese herbal formulations in addressing key pathological mechanisms related to CHF. These mechanisms include inflammation and oxidative stress, mitochondrial quality and energy metabolism disorders, myocardial remodeling, ferroptosis, and autophagy abnormalities. A multi-target framework is constructed by linking active ingredients from Chinese medicinal herbs, the signaling pathways they regulate, and the corresponding pathological mechanisms involved in CHF. Further integrating the classification background of HFrEF, HFmrEF, and HFpEF, this paper analyzes the potential differential focal roles of TCM-related mechanisms across different heart failure subtypes and pathological processes, and discusses existing problems in current research in the aspects of evidence hierarchy, druggability of active components, quality control, and clinical translation, as well as other related fields. This paper aims to provide a reference for subsequent research on TCM-based prevention and treatment of CHF.\n\nID: 42406192\nTitle: Dissecting PANoptosis in the Nervous System: A Unified Cell-Death Mechanism Driving Neuroimmune Activation and Chronic Neuroinflammation.\nAbstract: PANoptosis, a collective form of programmed cell death that includes apoptosis, necroptosis, and pyroptosis, is turning out to be a key player in the neuroimmune activation and sustaining chronic neuroinflammation in the nervous system. PANoptosis, in contrast to single cell death mechanisms, is a web of events coordinating neuronal death, glial cell changes, and inflammatory signals, being implicated in the initiation and progression of neurodegenerative and neuroinflammatory diseases. This review compiles current knowledge of the molecular pathways of PANoptotic signaling, its interaction with autophagy and immune pathways, and the in vivo models utilized for its pathogenic role in the central nervous system. We also tackle translational hurdles such as biomarker identification, therapeutic safety, disease, stage precision, and patient heterogeneity, which all point to the necessity of highly accurate interventions. Moreover, novel techniques combining systems biology, AI-based target identification, and personalized neuroimmunomodulation may effectively harness PANoptosis regulation to be both controlled and disease-specific. Through bridging the gap between the mechanistic insights and the translational perspectives, this review points out that PANoptosis provides a comprehensive basis for neuroimmune-associated pathology and represents a viable target for novel therapeutic approaches to counteract both chronic neuroinflammation and neurodegeneration.\n\nID: 42406105\nTitle: Agmatine induces mitophagy via the PTS-I2R pathway to increase autophagic flux and attenuate sepsis-induced intestinal epithelial cell apoptosis.\nAbstract: The therapeutic options for sepsis-induced intestinal injury, which drives multiple organ dysfunction and mortality, are limited, but the role of polyamine supplements remains unclear. This study aimed to elucidate the protective effect of agmatine (AGM) on sepsis-induced intestinal injury and its mitochondrial-targeted antiapoptotic mechanism in intestinal epithelial cells (IECs). We verified the transport and subcellular localization of AGM in IECs via fluorescence assays and established in vitro and in vivo IEC apoptosis models. Functional evaluations using cell viability assays, laser confocal imaging, flow cytometry, transmission electron microscopy, and multiomics techniques were performed. AGM attenuated sepsis-induced intestinal injury, as evidenced by its ability to lower the serum levels of intestinal damage markers in septic mice, attenuate inflammatory factor production and pathological damage in the intestine, and reduce IEC apoptosis. AGM entered IECs via the polyamine transport system (PTS), but not the NMDA receptor, and inhibited IEC apoptosis induced by TNF\u03b1/CHX or TNF\u03b1/ActD. Notably, AGM exerted its antiapoptotic effect by targeting the mitochondrial imidazoline I2 receptor (I2R). Mechanistically, AGM induced mitophagy by decreasing the mitochondrial membrane potential without altering mitochondrial number or function, as ROS production, calcium ion influx, ATP generation, and oxygen consumption were unchanged. AGM also increased autophagic flux, as confirmed upon treatment with various autophagy inhibitors. AGM alleviates sepsis-induced intestinal injury via the PTS-I2R axis by promoting mitophagy and autophagic flux to inhibit IEC apoptosis, laying a foundation for the use of AGM as a potential nutritional supplement or therapeutic agent for sepsis-induced intestinal injury.\n\nID: 42406096\nTitle: Milder Form of Vici Syndrome Due to Novel Missense Variant in Epg5 Gene Affecting Splicing: A Case Report.\nAbstract: Objective. Vici syndrome is a rare neurodevelopmental disorder with multisystem involvement, caused by mutations in the EPG5 gene encoding a protein involved in autophagy. It includes dysgenesis of the corpus callosum, cataracts, hypopigmentation, cardiomyopathy, and immuno-deficiency. Here we report a case of a 9-year-old boy of Roma ethnicity with a milder form of Vici syndrome and a novel variant in the EPG5 gene. Methods. DNA and RNA were extracted from the whole blood. Whole exome sequencing was performed and analysed with an in-house bioinformatics pipeline. A mini-gene assay was performed for EPG5 exon 23 with or without the tested variant. Results. The patient was born prematurely and presented with hypotonia, severe hypotrophy and growth retardation, developmental delay, congenital heart defects, mild brain atrophy, and a thin corpus callosum. Whole exome analysis identified a novel variant c.4205G>A, p.(Arg1402Lys) in the EPG5 gene, suggesting the diagnosis of Vici syndrome. Further examination of symptoms commonly associated with Vici syndrome confirmed hypopigmented skin areas and immunodeficiency. No seizures, cataracts, or cardiomyopathy were observed. As the variant is located at the last base of exon 23, we sequenced the patient's EPG5 mRNA and detected aberrant transcripts in addition to correctly spliced ones. The mini-gene assay confirmed decreased inclusion of the mutated exon compared with the wild-type (40% vs. 72%, respectively). Conclusion. Novel variant EPG5:c.4205G>A, p.(Arg1402Lys) causes aberrant splicing only in a small proportion of transcripts; therefore, the milder presentation of Vici syndrome in our patient is probably due to the residual presence of EPG5 protein.\n\nID: 42406081\nTitle: UBE2L6 promotes invasion and metastasis of triple-negative breast cancer by enhancing autophagy through STK38 ISGylation.\nAbstract: Although aberrant activation of autophagy is well known in triple-negative breast cancer (TNBC), its functional roles and underlying mechanisms remain largely unknown. In the present study, we found that high UBE2L6 expression was strongly associated with aggressive clinical features in TNBC. We demonstrated that UBE2L6 promoted migration, invasion, and lung metastasis of TNBC by enhancing STK38-mediated autophagy. Mechanistically, UBE2L6 stabilized STK38 by promoting its ISGylation and inhibiting its ubiquitin-proteasomal degradation. Therefore, targeting UBE2L6 and modulating the STK38 ISGylation-autophagy axis represent potential intervention points in TNBC.\n\nID: 42406070\nTitle: Off-target anti-leukemic effects of antibiotics: mechanisms and therapeutic insights.\nAbstract: Antibiotics are among the transformative advances in medicine, but many interact with mammalian cellular targets and pathways beyond their antimicrobial activity. A clinically important expression of these off-target effects is hematologic toxicity, including immune-mediated cytopenias and direct bone marrow suppression. This narrative review examines whether the same biology that injures normal hematopoietic cells can, in selected contexts, reveal therapeutically exploitable vulnerabilities in leukemia. We synthesize molecular, clinical, and preclinical evidence and organize it into an integrative framework linking mitochondrial translation inhibition, mitonuclear imbalance, oxidative phosphorylation failure, reactive oxygen species generation, DNA/topoisomerase stress, autophagy and lysosomal-flux blockade, and apoptosis modulation with both hematotoxicity and antileukemic activity. The strongest preclinical evidence supports selected tetracyclines, macrolides, and oxazolidinones, whereas evidence for beta-lactams, glycopeptides, polymyxins, rifamycins, fluoroquinolones, and folate-pathway agents remains more limited or largely hypothesis-generating. Importantly, antibiotic-induced cytopenia should not be interpreted as proof of leukemia selectivity: immune-mediated toxicity, supratherapeutic in vitro exposure, normal progenitor injury, pharmacokinetic constraints, microbiome effects, and resistance mechanisms all narrow the translational window. Overall, antibiotic hematotoxicity is best viewed as a biologically informative signal that can guide mechanism-based repurposing and combination strategies, but clinical development requires rigorous pharmacokinetic/pharmacodynamic validation, normal hematopoietic comparators, and biomarker-driven patient selection.\n\nID: 42405902\nTitle: Correction to \"Effects of Autophagy Inhibition by SAR405, a Selective VPS34 Inhibitor, on Pleural Mesothelioma Cells\".\nAbstract: \n\nID: 42405824\nTitle: Chronic kidney disease in women: Global trends and metabolic-cardiovascular associations.\nAbstract: The global burden of chronic kidney disease (CKD) is rapidly increasing due to the rising prevalence of metabolic diseases. However, the epidemiological characteristics of CKD in women and its epidemiological association with metabolic disorders and cardiovascular diseases (CVDs) remain unclear. Based on data from the Global Burden of Disease study 2021, this research used Joinpoint regression analysis to identify the global trends of CKD in women. A comprehensive assessment of CKD burden in women was conducted across multiple dimensions, such as age stratification, five CKD subtypes, sociodemographic index, decomposition analysis, risk factors, and CVD attributable to kidney function impairment. In 2021, the global number of women with CKD reached 359 million, an increase of 90.65% compared to 1990, with the absolute number of diabetic kidney disease cases nearly doubling. Nearly two-thirds of patients were postmenopausal women, and their age-standardized mortality rate and age-standardized disability-adjusted life-years (DALYs) rate had significantly increased to 64.03 and 1493.31 per 100,000, respectively. The age-standardized prevalence rate among women of reproductive age demonstrated a continuous upward trend (average annual percentage change, 0.13%). Regionally, the age-standardized mortality rate and age-standardized DALY rate of women with CKD were highest in the regions with low and low-middle sociodemographic index (SDI), while the age-standardized prevalence rate was highest in low-middle SDI regions. Metabolic risk factors constituted the main attributable risk factors for CKD in women, with risks owing to high fasting glucose and high body mass index rapidly increasing among women of reproductive age (by 40.66% and 112.17%, respectively). CVD attributable to kidney function impairment accounted for 18.19 million DALYs, representing 46.70% of the total disease burden, with ischemic heart disease being the main contributor. Population growth (58.63%) and aging (26.64%) were the main drivers of the increasing burden of CKD in women. In the future, women will face severe metabolic-renal-cardiac health challenges related to metabolic disorders.\n\nID: 42405585\nTitle: Targeted Inhibition of RPA3 Impairs Breast Cancer Progression Through Suppressing TGF-\u03b2 Signaling Pathway-Mediated Autophagy.\nAbstract: As a key component of the replication protein A (RPA) complex, RPA3 has been identified as oncogenic in multiple solid tumors. However, its specific role in breast cancer remains poorly understood. RPA3 expression and its prognostic relevance in breast cancer were assessed based on the public databases. To further confirm the biological function of RPA3, we knocked down RPA3 in the breast cancer cell line Michigan Cancer Foundation-7 (MCF-7) and then conducted Cell Counting Kit-8, colony formation, Western blot, immunofluorescence, and transmission electron microscopy. In vivo effects of RPA3 were tested in a xenograft model. We found that high expression of RPA3 in breast cancer predicted adverse patient outcomes. RPA3 was mainly involved in multiple oncogenic signaling pathways, including the transforming growth factor-\u03b2 (TGF-\u03b2) pathway. RPA3 knockdown effectively suppressed cancer cell proliferation in vitro and in\u00a0vivo. Mechanistically, RPA3 knockdown decreased TGF-\u03b21 promoter activity and reduced TGF-\u03b21 expression at mRNA and protein levels, accompanied by decreased p-Smad2/3 levels. RPA3 knockdown also significantly blocked autophagy, as evidenced by decreased microtubule-associated protein 1 light chain 3 (LC3)-II/LC3-I ratio, increased sequestosome 1 (p62) level, and reduced LC3 puncta. Notably, pharmacological activation of the TGF-\u03b2 pathway partially reversed autophagy alterations induced by RPA3 knockdown. These data support the possibility of RPA3 as a therapeutic target for breast cancer.\n\nID: 42405574\nTitle: The Plant RABC1 GTPase Coordinates with Exocyst Component SEC5A in Regulating ER-phagy under Endoplasmic Reticulum Stress.\nAbstract: Small GTPase proteins regulate intracellular transport between endomembrane compartments, yet their roles in endoplasmic reticulum (ER) stress responses and selective autophagy remain poorly understood. Here we characterize the plant RAB GTPase RABC1 as a regulator of ER-phagy during ER stress. Our results demonstrate that rabc1 mutants are hypersensitive to heat shock and ER stress inducers dithiothreitol and tunicamycin. RABC1 localizes primarily to the ER and Golgi with partial trans-Golgi network (TGN) association. Upon ER stress, RABC1 is recruited to autophagosomes and subsequently delivered into the vacuole. Autophagic turnover of the ER chaperone Calnexin (CNX1)-GFP is impaired in the rabc1 mutant after DTT and TM treatments. Additionally, RABC1 interacts with the exocyst subunit SEC5A in planta, and this interaction is required for SEC5A recruitment to autophagosomes, promoting autophagosome formation. Double-mutant analysis indicates an additive genetic interaction between RABC1 and SEC5A in ER stress sensitivity. Taken together, our results suggest that RABC1 coordinates with SEC5A to promote autophagosome formation and ER-phagy during ER stress, revealing a novel mechanism by which a plant RAB GTPase regulate ER-phagy.\n\nID: 42405496\nTitle: Zingerone ameliorates ovarian impairment by regulating steroidogenesis and apoptosis in letrozole-treated mouse.\nAbstract: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, disrupted folliculogenesis, and subfertility. This study evaluated the therapeutic efficacy of zingerone(4-(4-hydroxy-3-methoxyphenyl)-2-butanone) in a letrozole-induced hyperandrogenised PCOS-like mouse model. Zingerone administration, particularly at 25 and 50\u2005mg/kg, significantly improved ovarian morphology by enhancing follicular development and corpus luteum formation. This was accompanied by increased granulosa cell proliferation (PCNA) and attenuation of apoptosis, evidenced by up-regulation of BCL2 and reduced TUNEL staining. Zingerone reprogrammed ovarian steroidogenesis by reducing circulating testosterone, down-regulating androgen receptor expression, suppressing StAR, and up-regulating aromatase, thereby promoting a shift toward estrogen biosynthesis. Autophagy analysis indicated restoration of autophagic flux, reflected by decreased p62 levels and modulation of Beclin1 and LC3B expression. These coordinated molecular and cellular changes resulted in functional recovery, with significant improvement in fertility and litter size at higher doses (25 and 50\u2005mg/kg). Collectively, zingerone exerts dose-dependent, multi-target effects to restore endocrine, cellular, and autophagic homeostasis, thereby ameliorating ovarian dysfunction in PCOS.\n\nID: 42405405\nTitle: Precision Nanotechnology in Oral Oncology: From Biomarker-Guided Targeting to AI-Driven Theranostics.\nAbstract: Oral squamous cell carcinoma (OSCC) is a serious malignancy characterised by poor outcomes, late identification, therapeutic resistance, and the adverse effects associated with radiation therapy, surgery, and chemotherapy. Nanotechnology-based drug delivery provides modular approaches that improve intratumoral accumulation, safeguard payloads, and facilitate controlled release, all while reducing off-target damage. This review compiles the latest findings in the field of oral cancer targeting magnetic nanomaterials, cyclodextrins, quantum dots, dendrimers, and metallic/inorganic platforms (metal-organic frameworks). Mechanistic innovations encompass both passive and active targeting strategies (e.g., EGFR, folate, CD44), stimuliresponsive mechanisms (pH, enzyme), and precision systems guided by salivary biomarkers (e.g., IL-8, CYFRA 21-1), ultimately leading to enhanced therapeutic indices and real-time theranostic monitoring. Innovative approaches use AI-driven design, biosensor-facilitated early detection, and Nanovaccine/immunenanomedicine techniques to personalise treatment in the multifaceted oral tumour microenvironment. Translational challenges remain, including heterogeneous EPR effects, nanotoxicology (encompassing autophagy and ROS pathways), manufacturing scale-up, and regulatory standardisation. These issues require the development of robust pharmacology-toxicity frameworks and biomarker-driven clinical trials. Nanocarriers of the future may revolutionise OSCC treatment by bringing together materials science, tumour biology, and genetic and salivary signals that are unique to each patient. This will allow for safer, more effective, and quantifiable precision therapies.\n\nID: 42405401\nTitle: Resveratrol and the NLRP3 Inflammasome: Unlocking the Anti-inflammatory Potential of a Natural Compound.\nAbstract: Chronic inflammation is the basis of various diseases, including inflammatory bowel disease, neurodegenerative diseases, and cardiometabolic disorders. NLRP3 is a key player in controlling Interleukin-1\u03b2 (IL-1\u03b2) and Interleukin-18 (IL-18) maturation and pyroptosis via its NOD-like receptor pyrin domain-containing 3 (NLRP3) inflammasome. This review will assess the mechanistic and therapeutic opportunity of resveratrol in restraining the NLRP3 inflammasome activation. A search of experimental and preclinical studies examining the impact of resveratrol on oxidative stress, inflammatory signaling, mitochondrial activity, and inflammasome activation in various disease models was performed. Resveratrol reduces oxidative stress by regulating reactive oxygen species-mediated nuclear factor erythroid 2-related factor 2 signaling and suppressing toll-like receptor 4 (TLR4) /nuclear factor kappa B signaling (NF-\u03baB). It maintains mitochondrial integrity by activating sirtuin 1 and AMP-activated protein kinase signalling. In models of acute lung injury, bronchitis, diabetic nephropathy, and neurodegeneration, resveratrol can suppress the expression of NLRP3, caspase-1, and IL-1\u03b2, promote autophagy, and prevent dopaminergic neurons through the PINK1/Parkin/NLRP3 pathway. Additionally, it enhances intestinal barrier integrity in dextran sulfate sodium-induced colitis and suppresses inflammasome-mediated inflammation. These results suggest that resveratrol regulates the priming and activation stages of NLRP3 inflammasome signaling by inhibiting oxidative stress, mitochondrial dysfunction, and inflammatory cascades based on redox signaling. Nanoparticle preparations and structural analogs, such as pterostilbene, improve stability, bioavailability, and specific delivery. Resveratrol is a potential natural therapeutic agent for managing NLRP3 inflammasomemediated inflammation, and its efficacy is enhanced when administered in optimal formulations and combined with conventional anti-inflammatory agents.\n\nID: 42404999\nTitle: SPG7-Mediated Regulation of mPTP and Mitochondrial Flickering in COPD: A Bioinformatics-Based Prediction of Mechanistic Framework.\nAbstract: During the staged progression of chronic obstructive pulmonary disease (COPD), mitophagy homeostasis is disrupted and exhibits a typical dual role. Mitophagy is tightly regulated by ion channel-controlled mitochondrial membrane potential (\u0394\u03a8m) and may associate with mitochondrial permeability transition pore (mPTP) dynamics. However, this regulatory mechanism remains largely unknown, and the stage-specific requirements of mitophagy in COPD progression have yet to be established. This study proposed a novel theoretical framework from prior literature. Using public databases, we linked mPTP-related genes to COPD state transitions via differential analysis and Mendelian randomization (MR). Key biomarkers were validated through gene enrichment, functional annotation, immune infiltration, and single-cell RNA sequencing (scRNA-seq) to assess biological significance. Finally, molecular docking confirmed their potential roles. We preliminarily aligned the \"mitochondria-cell survival architecture\" hypothesis with COPD progression. Compared with stable COPD (STCOPD), acute exacerbation of COPD (AECOPD) showed massive type II alveolar epithelial (AT2) cell death, hyperinflammation, increased energy demand, and impaired intercellular communication, consistent with activated ubiquitin-proteasome system (UPS), mitochondrial gene expression, macroautophagy initiation, and vesicle trafficking. Six biomarkers (including SPG7) were associated with AECOPD (AUC=0.705, 95% CI 0.554-0.705). SPG7 was positively correlated with AECOPD (OR=1.126, 95% CI 1.008-1.257), while the other five showed negative correlations. These markers were enriched in ion channel and G protein-coupled receptors (GPCRs) pathways. SPG7 expression paralleled energy demand and strongly interacted with AFG3L2 and PPIF, implicating it in mPTP regulation. This study preliminarily supports the mitochondria-cell survival hypothesis. Bioinformatic analysis suggests that mPTP-triggered mitochondrial flickering maintains mitochondrial quality control. Furthermore, transient mPTP opening via SPG7-mediated CypD activation may constitute an independent protective pathway, potentially involving unique SPG7-CypD modifications. However, non-significant colocalization limits study robustness, necessitating rigorous experimental validation of these predictions.\n\nID: 42404975\nTitle: CCL2 regulates autophagy through the TNF signaling pathway to promote traumatic brain injury progression.\nAbstract: This study investigated the regulatory role of CCL2 in traumatic brain injury (TBI) and elucidated its underlying molecular mechanism. Bioinformatics analysis revealed significant enrichment of CCL2 in the TNF signaling pathway. ELISA and Western blot analyses confirmed marked upregulation of CCL2 in the serum of TBI patients as well as in the serum and brain tissues of TBI mouse models. Functional experiments demonstrated that CCL2 knockdown significantly alleviated neurological impairment and secondary brain injury in TBI mice. Mechanistically, CCL2 suppression enhanced neuronal autophagy, as evidenced by increased Beclin1 and LC3-II expression and modulation of autophagy flux markers (p62 and LAMP2), while simultaneously attenuating neuronal apoptosis through regulation of apoptosis-related proteins, including Bcl-2, Bax, and cleaved caspase-3. Rescue experiments further showed that TNFR1 overexpression abolished the protective effects of CCL2 knockdown and restored activation of the TNF signaling pathway, accompanied by elevated MCP-1, TNFR1, and phosphorylated p65 levels. Collectively, these findings demonstrate that CCL2 promotes TBI progression by activating the TNF signaling pathway, thereby suppressing autophagy and enhancing apoptosis. Targeting the CCL2-TNFR1 axis may represent a promising therapeutic strategy for secondary brain injury following TBI.

This review presents current evidence linking neurotropic viruses and host antiviral immunity to the onset and progression of neurodegeneration and neurocognitive dysfunction. We explore how viral infections, particularly by Herpesviruses, Severe Acute Respiratory Syndrome Coronavirus 2, and Human Immunodeficiency Virus, disrupt neural homeostasis through neuroinflammation, amyloidosis, tauopathy, and autophagy dysregulation in neurodegeneration including Alzheimer's disease (AD). Simultaneously, host antiviral mechanisms, including type I interferons and interferon regulatory factors, often amplify neuronal damage when dysregulated. By examining viral and immune interactions within the neurodegenerative diseases, this review aims to broaden our understanding of the viral-immune axis in the brain and inspire novel approaches to prevention and treatment.\n\nID: 42404408\nTitle: A conductive MXene hydrogel reprograms immunity and autophagy to restore neurovascular repair in infected wounds.\nAbstract: Multidrug-resistant bacteria-infected wounds are difficult to heal due to persistent infection, excessive inflammation, impaired angiogenesis and deficient cutaneous innervation. Here, we develop an antibacterial and conductive bioactive hydrogel based on flower-shaped MXene microspheres for treating methicillin-resistant Staphylococcus aureus (MRSA)-infected wounds. The hydrogel (PDM) is constructed by integrating \u03b5-poly-L-lysine-functionalized MXene microspheres into a dynamically crosslinked oxidized pullulan network via pH-responsive Schiff-base chemistry, conferring injectability, self-healing, tissue adhesion and environmental responsiveness. PDM effectively eliminates MRSA biofilms, scavenges reactive oxygen species and attenuates inflammatory responses while promoting adaptive autophagy. These combined properties enable modulation of the wound microenvironment, enhance macrophage polarization toward a regenerative phenotype and support cell proliferation, endothelial cell migration and angiogenesis. In addition, the conductive hydrogel promotes Schwann cell maturation and neurotrophic factor expression, facilitating reconstruction of the neurogenic microenvironment. In a murine full-thickness MRSA-infected wound model, a single application of PDM significantly accelerates wound closure, enhances cutaneous innervation and reduces fibrosis. This work presents a multifunctional MXene-based hydrogel platform for antibiotic-free infected wound healing.\n\nID: 42404106\nTitle: Emerging Role of Sirtuins-Mediated Ferroptosis in Hepatocellular Carcinoma Progression: Mechanisms and Therapeutic Perspectives.\nAbstract: Hepatocellular carcinoma (HCC) ranks as the most common type of primary liver cancer, characterized by rapid tumor growth and therapeutic resistance. Evading cell death is a key characteristic of multiple cancers, including HCC. Many programmed cell death (PCD) processes, comprising apoptosis, autophagy, necroptosis, and ferroptosis, have been identified to affect tumor growth and recurrence of HCC. Ferroptosis is an emerging iron-dependent PCD mode characterized by lipid peroxidation and iron accumulation. It has emerged as a critical regulatory mechanism in HCC progression. Sirtuins (SIRTs), a class III histone deacetylases (HDACs) that require NAD+ as a cofactor, exhibit exclusive and poised functions in the pathophysiological processes of cancers by mediating ferroptosis. However, a summary of the mechanisms of SIRT-mediated ferroptosis in HCC development and associated therapeutic strategies is limited. This article provides an outline of recent developments in the role of SIRTs in HCC proliferation, metastasis, and the development of multidrug resistance. We highlight the roles and mechanisms of SIRTs in mediating ferroptosis in HCC, aiming to provide a comprehensive and novel perspective for developing diagnostic biomarkers and therapeutic strategies for HCC, thereby advancing the understanding of HCC pathogenesis and treatment.\n\nID: 42403958\nTitle: SUMOylation inhibitor TAK-981 suppresses proliferation and induces apoptosis in SK-UT-1B uterine leiomyosarcoma cells.\nAbstract: Uterine leiomyosarcoma (Ut-LMS) is an aggressive smooth muscle malignancy with limited therapeutic options and a poor prognosis, underscoring the need for new molecularly-targeted therapies. TAK-981 (subasumstat), a selective inhibitor of small ubiquitin-like modifier (SUMO)-activating enzymes, exhibits antitumor activity in several types of cancer; however, to the best of our knowledge, its therapeutic potential in Ut-LMS has not been explored. The current study evaluated the effects of TAK-981 on human Ut-LMS cells and revealed that SK-UT-1B cells exhibited markedly greater sensitivity to TAK-981 than SK-UT-1 cells. TAK-981 substantially reduced SK-UT-1B cell viability in a time- and concentration-dependent manner, whereas SK-UT-1 cells demonstrated a minimal response to TAK-981 at similar doses. Annexin V staining confirmed that TAK-981 induced the apoptosis of SK-UT-1B cells after 48 h, with apoptotic populations increasing proportionally with drug concentration. Furthermore, TAK-981 induced G0/G1 cell cycle arrest and markedly decreased Ki67 expression, indicating suppressed proliferative activity. TAK-981 also triggered substantial intracellular reactive oxygen species (ROS) accumulation and mitochondrial membrane depolarization, and antioxidant co-treatment demonstrated that apoptosis was partially ROS-dependent. Western blotting indicated robust inhibition of SUMO2/3 conjugation and activation of apoptotic markers, including cleaved caspase-3 and poly (ADP-ribose) polymerase, with the upregulation of p21 and p53. By contrast, autophagy markers, such as LC3B and p62, were unchanged, indicating that TAK-981 exerted its cytotoxic effects independently of the autophagic pathway. Collectively, these findings suggested that TAK-981 suppressed proliferation and induced apoptosis in SK-UT-1B Ut-LMS cells, accompanied by SUMOylation inhibition, ROS-associated mitochondrial dysfunction, apoptosis and G0/G1 cell-cycle arrest, and may represent a promising therapeutic candidate for further investigation in Ut-LMS.\n\nID: 42403159\nTitle: Autophagy-related pathway dysregulation and apoptosis suppression in pterygium: Role of key biomarkers Beclin-1, ATG5, LC3, p62, and Bcl-2 in pathogenesis and potential nonsurgical targets.\nAbstract: ObjectivesTo investigate the roles of apoptosis and autophagy in the pathogenesis of primary pterygium and to evaluate potential biomarkers that could lead to nonsurgical therapeutic approaches.MethodsIn this prospective, observational, controlled study, patients diagnosed with primary pterygium were included. Excised pterygium tissues (study group) were compared with normal conjunctival tissues obtained from autografts (control group). Immunohistochemical staining was used to assess the expression of autophagy-related proteins (Beclin-1, LC3A/B, ATG5, and p62) and apoptosis-related proteins (Bcl-2 and Caspase-8). Quantitative immunohistochemical evaluation was performed using H-score analysis with Image Tool Software.ResultsThe study group exhibited significant increases in the expression of Beclin-1 (97.65\u2009\u00b1\u20092.54 vs. 25.53\u2009\u00b1\u20090.4), LC3A/B (97.88\u2009\u00b1\u20095.35 vs. 61.73\u2009\u00b1\u20095.08), ATG5 (100.73\u2009\u00b1\u20091.06 vs. 35.35\u2009\u00b1\u20090.3), p62 (84.18\u2009\u00b1\u20093.59 vs. 59.54\u2009\u00b1\u20092.29), and Bcl-2 (107.36\u2009\u00b1\u20091.60 vs. 53.56\u2009\u00b1\u20091.38) compared with the control group (p\u2009<\u20090.001 for all). Although Caspase-8 expression was also increased (65\u2009\u00b1\u20091.53 vs. 49\u2009\u00b1\u20090.2), the difference was not statistically significant (p\u2009=\u20090.270). These findings suggest altered regulation of autophagy-related pathways accompanied by suppression of apoptotic mechanisms, which may contribute to the persistence, fibrovascular proliferation, and progression of pterygium tissue.ConclusionThe progression of pterygium appears to be associated with dysregulation of autophagy-related pathways and inhibition of apoptotic mechanisms. These findings suggest that modulation of these cellular mechanisms may provide novel pharmacological therapeutic options, potentially reducing the need for surgical intervention.\n\nID: 42402967\nTitle: Hypoxia-preconditioned dental pulp stem cells alleviate acetaminophen-induced liver failure via promoting MYC-HIF1A/HIF-1\u03b1-BNIP3-mediated mitophagy.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is a prevalent clinical liver condition caused mostly by oxidative stress and mitochondrial damage. Dental pulp stem cells (DPSCs) possess antioxidant, anti-inflammatory, and immunomodulatory capabilities, demonstrating significant potential in liver diseases. However, during in vitro culture, they are typically maintained under normoxic conditions (21% O2), which is very different from the hypoxic oxygen level that is found in vivo. It remains unclear whether hypoxic-conditioned dental pulp stem cells (Hyp-DPSCs) exhibit superior therapeutic effects compared to normoxic-conditioned dental pulp stem cells (Nor-DPSCs). This study demonstrated that 24-h exposure to 1% O2 significantly enhanced HIF1A/HIF-1\u03b1 expression in DPSCs. It promoted mitophagy through the MYC-HIF1A-BNIP3 pathway, enhancing mitochondrial shape and function while reducing oxidative stress in DPSCs. Furthermore, in vitro and in vivo experiments demonstrated that Hyp-DPSCs were far more potent than Nor-DPSCs in boosting the expression of hepatic antioxidant factors and enhancing macroautophagy/autophagy to reduce AILI. These findings revealed that hypoxia activated mitophagy in DPSCs, enhancing their therapeutic efficacy against AILI and providing a novel strategy for stem cell-based AILI treatment.Abbreviations: AILI: acetaminophen-induced acute liver injury; ANOVA: analysis of variance; APAP: acetaminophen; BAX: BCL2 associated X, apoptosis regulator; BCL2: BCL2 apoptosis regulator; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CASP3: caspase 3; CAT: catalase; CCK-8: cell counting kit-8; CM: conditioned medium; COX4I1: cytochrome c oxidase subunit 4I1; CPT1A: carnitine palmitoyltransferase 1A; CQ: chloroquine; DPSCs: dental pulp stem cells; ELISA: enzyme-linked immunosorbent assay; GO: Gene Ontology; GOT1/AST: glutamic-oxaloacetic transaminase 1; GPT/ALT: glutamic - pyruvic transaminase; GPX4: glutathione peroxidase 4; GSH: glutathione; Hyp-DPSCs: hypoxic-conditioned dental pulp stem cells; H&E: hematoxylin and eosin; HIF1A/HIF-1\u03b1: hypoxia inducible factor 1 subunit alpha; HMOX1/HO-1: heme oxygenase 1; HUVECs: human umbilical vein endothelial cells; IF: immunofluorescence; IHC: immunohistochemistry; IL1B/IL-1\u03b2: interleukin 1 beta; IL6: interleukin 6; i.p.: intraperitoneally; i.v.: intravenous injection; KEGG: Kyoto Encyclopedia of Genes and Genomes; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MSCs: mesenchymal stem cells; MYC: MYC proto-oncogene, bHLH transcription factor; NAC: N-acetylcysteine; NAPQI: N-acetyl-p-benzoquinone imine; NFE2L2/NRF2: NFE2 like bZIP transcription factor 2; Nor-DPSCs: normoxic-conditioned dental pulp stem cells; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PLIN2: perilipin 2; PINK1: PTEN induced kinase 1; PPARA/PPAR\u03b1: peroxisome proliferator activated receptor alpha; PPARG/PPAR\u03b3: peroxisome proliferator activated receptor gamma; ROS: reactive oxygen species; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TEM: transmission electron microscopy; TNF/TNF-\u03b1: tumor necrosis factor; TOMM20: translocase of outer mitochondrial membrane 20; VDAC1: voltage dependent anion channel 1; WB: western blot.\n\nID: 42402931\nTitle: Mir452 protects against septic acute kidney injury by targeting Apaf1 to relieve CASP9-mediated suppression of autophagy.\nAbstract: Septic acute kidney injury (AKI) is associated with high mortality and currently lacks effective therapeutics. Mir452 (microRNA 452) is a newly identified, highly sensitive biomarker for septic AKI, but the biological function of Mir452 was unknown. Here we report that Mir452 protects kidney tubular cells in septic AKI by repressing APAF1 (apoptotic peptidase activating factor 1) and associated caspase activation to preserve macroautophagy/autophagy. Using mouse and cell models of septic AKI induced by lipopolysaccharide (LPS), we found that inhibition of Mir452 exacerbated renal dysfunction, tubular apoptosis, and inflammatory responses, whereas Mir452 mimics significantly attenuated kidney injury. Mechanistically, Mir452 was shown to directly bind to the 3' untranslated region (3'UTR) of Apaf1 mRNA, repressing APAF1 expression and thereby inhibiting apoptosome-mediated CASP9 activation. This repression further alleviated caspase-mediated cleavage of autophagy-related proteins like BECN1 and ATG5, leading to the preservation of autophagic flux, which in turn limits inflammasome activation and inflammation. Notably, tubule-specific deletion of Apaf1 recapitulated the protective effects of Mir452, whereas forced Apaf1 expression aggravated injury, an effect reversed by CASP9 knockdown. Furthermore, Mir452 significantly promotes protective autophagy in septic AKI by suppressing the APAF1-CASP9 axis, as evidenced by upregulated ATG5 and BECN1 expression, enhanced LC3-II accumulation and autophagosome-lysosome fusion, along with reduced SQSTM1/p62 levels. Functional rescue experiments demonstrated that Mir452's anti-inflammatory effects depend entirely on activated autophagy, as overexpression fails when autophagy is inhibited. Together, the results unveil the Mir452-APAF1-CASP9-autophagy signaling axis that provides an intrinsic anti-inflammation and anti-apoptosis mechanism, suggesting new therapeutic targets for septic AKI.\n\nID: 42402729\nTitle: The dual role of Ganoderma lucidum polysaccharides in cancer treatment: Meridian tropism-based direct inhibition and immune-mediated modulation.\nAbstract: Ganoderma lucidum, a highly valued medicinal mushroom in Traditional Chinese Medicine (TCM), has a long history of clinical use. Although its immunomodulatory and anticancer properties have been extensively investigated, an integrated framework connecting traditional therapeutic principles with modern molecular pharmacology remains underdeveloped. This review proposes a novel meridian-based pharmacological framework that bridges classical TCM theory with contemporary precision oncology. Specifically, the direct tumor-suppressive effects of G. lucidum polysaccharides (GLPs) across organ-specific malignancies, including lung, liver, hematological, and genitourinary cancers, are systematically examined to explore potential associations between classical meridian tropism and tissue-specific anticancer activity. These organ-targeted effects are further linked to experimentally validated mechanisms, including cell-cycle arrest, apoptosis induction, DNA repair interference, autophagy modulation, inhibition of epithelial-mesenchymal transition, and sensitization to chemotherapy. Beyond their direct tumor-suppressive effects, GLPs also exhibit potent immunomodulatory activities that may enhance cancer immunotherapy. Their roles in regulating systemic immunity and remodeling the tumor microenvironment are highlighted through macrophage reprogramming, dendritic cell maturation, and cytotoxic T-cell activation, together with their potential synergistic interactions with immune checkpoint blockade therapies. By integrating direct tumor suppression with immune-mediated mechanisms within a meridian-based framework, this review provides a comprehensive perspective on the therapeutic potential of GLPs and offers insights to support their future clinical translation in oncology.\n\nID: 42402699\nTitle: CAMKV is an ISG and facilitates the degradation of rabies virus phosphoprotein via SQSTM1-mediated selective autophagy.\nAbstract: Once rabies virus (RABV) gains access to the central nervous system, infection almost inevitably results in fatal outcomes, and our incomplete understanding of viral pathogenesis remains a major barrier to effective therapeutic intervention. Here, we identify CAMKV as an interferon-stimulated gene (ISG) that drives the macroautophagic/autophagic degradation of RABV phosphoprotein (P), thereby potently suppressing viral replication in vitro. Notably, in vivo overexpression of CAMKV significantly delays disease progression in mice challenged with a street strain of RABV. Mechanistically, CAMKV interacts with both RABV P and SQSTM1, promoting SQSTM1-mediated selective autophagic clearance of P and thereby restricting RABV transcription and replication. Collectively, our findings establish CAMKV as a critical host antiviral effector that functions through selective autophagy, highlighting CAMKV as a promising molecular target for the development of novel therapeutics against lethal RABV infection.

Increasing evidence suggests that functional coordination among membrane-bound organelles, including mitochondria, the endoplasmic reticulum (ER), lysosomes, peroxisomes, and the Golgi apparatus, contributes to cellular homeostasis during aging. However, the mechanisms linking kinase signaling to specific inter-organelle contact sites or communication pathways remain incompletely defined. In this review, we discuss current evidence linking major metabolic and stress-responsive kinases, including AMPK, pyruvate dehydrogenase kinases (PDKs), mTOR, AKT, and PERK, to organelle coordination in aging and age-related diseases. These kinases regulate mitochondrial dynamics, metabolic flux, calcium and lipid handling, autophagy, lysosomal function, proteostasis, and vesicular trafficking. In some contexts, kinase signaling intersects with defined organelle interfaces, such as mitochondria-associated ER membranes, whereas in many cases the effects on inter-organelle communication are indirect or inferred from broader changes in organelle function. We further discuss how kinase dysregulation may contribute to age-associated defects in mitochondria-ER, mitochondria-lysosome, mitochondria-peroxisome, and ER-Golgi coordination in neurodegeneration, cardiometabolic disease, cellular senescence, and inflammaging. By distinguishing direct contact-site regulation from indirect functional coordination, this review highlights kinase-regulated organelle communication as an emerging, but still incompletely resolved, framework for understanding cellular decline during aging.\n\nID: 42402646\nTitle: Acridocarpus orientalis ethanolic extract induces senescence and abortive autophagy in human breast cancer cells.\nAbstract: Breast cancer is the most frequently diagnosed cancer in women worldwide. Triple Negative Breast Cancer (TNBC), which lacks the expression of the hormonal Estrogen Receptor (ER) and Progesterone Receptor (PR), amplification of Human Epidermal Growth Factor Receptor 2 (HER2), is not responsive to the hormonal therapy. Currently, available chemotherapy and radiotherapy cause severe side effects; therefore, there is an urgent need for new therapeutic choices for TNBC. Acridocarpus orientalis is used in folk medicine to treat several health conditions. Here, evaluated the anti-cancer activity of Acriodocarpus orientalis Ethanolic Extract (AOEE) against two TNBC (MDA-MB-231 and Hs578T) and one luminal A (MCF-7) cell lines, and investigated the molecular mechanisms underlying its anticancer activity. The results revealed that AOEE inhibited cell proliferation of the three cell lines in a concentration- and time-dependent manner. The anti-proliferative effect of AOEE was found to be concomitant with the induction of cell cycle arrest at the G1/S phase. These changes were associated with upregulation of p21WAF1 and p27 Kip1, downregulation of PCNA, Cyclin D1, phospho-Rb. Moreover, AOEE induces abortive autophagy through upregulation of autophagy related proteins LC3-II, Beclin-1, and p62. Also, p16-dependent senescence was induced in AOEE treated MDA-MB-231 cells confirmed by senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) expression in the treated cells. AOEE induced activation of ERK and p38 pathways, which might be involved in autophagy and senescence induction. Acridocarpus orientalis could be a potential source for novel chemotherapeutic agents against TNBC.\n\nID: 42402611\nTitle: Dihydroartemisinin inhibits mutant KRAS to potentiate regorafenib plus anti-PD-1 in KRAS-mutant colorectal cancer liver metastases.\nAbstract: Colorectal cancer (CRC) is one of the most prevalent malignancies worldwide, and liver metastases stands as a leading contributor to its high mortality rate in advanced stages. Regorafenib plus anti-PD-1 is a new therapeutic option for patients with colorectal cancer liver metastases (CRCLM). However, a considerable number of patients have not benefited from it. In this study, KRAS mutation was identified associated with resistance to regorafenib plus anti-PD-1 in CRCLM. Dihydroartemisinin (DHA), a clinically approved anti-malaria agent, was verified to selectively downregulate KRASG12D mutant with no discernible influences on wild-type KRAS, which is consistent with the higher sensitivity of KRAS-mutant CRC cells and organoids to DHA treatment. In preclinical KRASG12D CRCLM models, DHA substantially potentiated the therapeutic efficacy of regorafenib plus anti-PD-1 by remodeling the tumor immune microenvironment, including enhancing the cytotoxicity of CD8+ effector T cells and promoting pro-inflammatory macrophage polarization. Mechanically, DHA could restore interferon response that was impaired by oncogenic KRAS mutations, and inhibit ERBB signaling activation induced by regorafenib. Collectively, these findings support DHA as a potential adjunct to regorafenib plus anti-PD-1 for KRASG12D CRCLM and suggest a therapeutic strategy with translational potential for KRAS-driven malignancies.Black arrows: Mutant KRAS can impair IFN response to inhibit CD8+ T cells anti-tumor immune response, thus attenuating the efficacy of PD-1 mAb therapy. Red arrows: DHA can inhibit mutant KRAS expression by promoting autophagy-lysosome pathway. Orange arrows: Regorafenib plays a role of anti-angiogenesis, but also probably induces ERBB signaling activation, which can inhibit IFN response via upregulating p-Erk1/2 and p-Akt, thus causing resistance to regorafenib treatment. Green arrows: The treatment of DHA can drive macrophages polarization to pro-inflammation phenotype (M1-like), probably via the enhancement of TNF\u03b1 expression. This Figure was produced by Figdraw.\n\nID: 42402587\nTitle: \u03b1-Synuclein triggers intercellular nanotubes formation to prevent apoptosis in astroglia by promoting stemness.\nAbstract: Astrocytes play a significant role in neuroprotection by internalizing neurodegenerative aggregates and facilitating their degradation. Recent studies indicate that \u03b1-Synuclein (\u03b1-SYN) protofibrils promote the transfer of pathogenic aggregates and dysfunctional mitochondria between astroglia via tunneling nanotubes (TNTs), which enhances cell survival and resistance to apoptosis. However, the underlying mechanism of TNT-driven apoptosis resistance remains unclear. We find that \u03b1-SYN protofibrils induce aberrant mitochondria with decreased membrane potential (\u03a8m) and promote dynamic actin remodeling by relocating phosphorylated focal adhesion kinase (pFAK) to the nucleus, which triggers TNT formation in human astrocytoma cell lines and primary murine astrocytes. The important novel finding of this study is that pFAK in the nucleus co-localizes with Nanog, a crucial transcription factor for preserving stemness, and the interaction between pFAK and Nanog is critical for promoting p53 degradation via Mdm2-mediated ubiquitination and upregulating autophagy, thereby supporting the survival of astroglia exposed to toxic \u03b1-SYN protofibrils. ROCK inhibitor y-27632 also drives TNT-formation via pFAK translocation to the nucleus, colocalizes with Nanog, and enhances stemness-related gene expression. Inhibiting TNT with the actin depolymerizing agent cytochalasin-D prevents pFAK co-localization with Nanog in the nucleus and fails to protect cells from \u03b1-SYN-induced apoptosis. Nanog knockdown does not degrade p53 and hinders cell rescue from apoptosis. Furthermore, these transient TNTs transfer mitochondria to adjacent cells, potentially helping maintain metabolic stability. This study reveals that the TNT formation pathway promotes pFAK-Nanog interaction in the nucleus, leading to p53 degradation, which protects astroglia against \u03b1-SYN proteotoxicity and prevents apoptosis.\n\nID: 42402325\nTitle: ROS as a powerful instrument for the advanced cancer prevention and management: Facts and outlook.\nAbstract: Reactive oxygen species (ROS) play a complex dual role in cancer biology. At physiological levels, ROS act as signaling molecules that drive tumorigenesis, metastasis, and therapy resistance by activating oncogenic pathways, such as NF-\u03baB and PI3K/AKT, and fostering an immunosuppressive microenvironment. Conversely, excessive ROS accumulation overwhelms antioxidant defenses, triggering oxidative stress that can selectively eliminate tumor cells. Consequently, manipulating the delicate redox equilibrium has emerged as a pivotal strategy for cancer treatment. This review systematically examines the multifaceted functions of ROS, bridging the gap between fundamental redox biology and clinical application within the Predictive, Preventive, and Personalized Medicine (3PM) framework. Beyond molecular mechanisms, we evaluated the rationale for utilizing mitochondrial redox signatures as intrinsic biological sensors to identify suboptimal health conditions (SHC) and prevent the health-to-disease transition. We elucidate the regulatory networks governing ROS production and elimination, highlighting their dual function in promoting genomic instability versus inducing distinct cell death modalities, including apoptosis, autophagy, necroptosis, and ferroptosis. Special attention is given to ROS-mediated remodeling of the tumor microenvironment (TME), where oxidative stress facilitates immunosuppression. Importantly, we provide expert recommendations on integrating digital health monitoring and patient stratification into clinical oncology. By emphasizing mitochondrial rejuvenation and individualised protection, this review discusses how proactive interventions can restore homeostasis and improve long-term outcomes, offering a cost-effective alternative to reactive treatments.\n\nID: 42402228\nTitle: Rational design and synthesis of TBC1D2 inhibitors: Augmenting autophagy to improve sorafenib sensitivity in hepatocellular carcinoma.\nAbstract: Drug resistance is a major barrier to effective hepatocellular carcinoma therapy, and autophagy targeting holds great potential for overcoming this issue. Using binding energy data from molecular docking with TBC1 domain family member 2 (TBC1D2) as the target, we rationally designed compound G2 featuring a piperazine moiety. Target binding was validated via a competitive immunofluorescence assay. The binding affinity of G2 was determined by surface plasmon resonance, yielding a dissociation constant (KD) of 0.4\u202f\u03bcM. Functional evaluation of G2 determined its aqueous solubility to be 0.3\u202fmg/mL, with a half-maximal inhibitory concentration value of 80\u202f\u00b1\u202f20\u202fnM and a selectivity index of 23.1 in HCCLM3 cells. Subsequent mechanistic investigations revealed that this selectivity arose from the heightened responsiveness of TBC1D2 expression to G2 in HCCLM3 cells, thereby inducing selective autophagic cell death. In HCCLM3 xenograft mouse models, G2 showed excellent hepatic retention. G2 monotherapy (58.2% tumor growth inhibition) and its combination with sorafenib (70.9%) exerted superior antitumor activity versus sorafenib monotherapy (52.8%), with favorable safety. Collectively, our findings establish G2 as a promising therapeutic candidate for surmounting sorafenib resistance, characterized by selective antitumor activity against malignant hepatocellular carcinoma.\n\nID: 42401806\nTitle: From nurse bee to queen egg: RNA-seq analysis of Apis mellifera eggs shows dietary protein-dependent gene regulation.\nAbstract: Honeybees, Apis mellifera, play a vital role as pollinators in global agricultural ecosystems. Nutrition, particularly dietary protein content, profoundly impacts honeybee health and reproduction. Yet, the molecular mechanisms connecting diet composition and gene expression in honeybee eggs remain underexplored. In this study, we investigate the intricate relationship between diet, gene expression, and honeybee egg development. Using RNA-seq analysis, we explore the effects of different protein-to-carbohydrate (P: C) ratios in honeybee diets on differential gene expression in the eggs laid by the queen and potential associated molecular responses. Our research identifies 1007 differentially expressed genes (DEGs) across various dietary conditions, highlighting the pivotal role of nutritional composition in shaping gene expression during egg development.Cluster analysis revealed two DEG profiles corresponding to low protein diets (LPD) and high protein diets (HPD). LPD conditions upregulate genes linked to protein catabolism, autophagy, and ubiquitin-mediated proteolysis, indicating potential cellular responses to nutritional stress. Conversely, HPD conditions upregulate genes related to RNA processing, spliceosome activity, and the MAPK signalling pathway, suggesting normal cellular development.Notably, the Hippo signalling pathway exhibits distinct gene regulation patterns under LPD and HPD conditions, potentially influencing cellular growth and differentiation in response to nutrient availability.Our findings underscore the critical role of nutrition in honeybee health and reproduction, providing insights into optimizing honeybee diets for colony health and resilience. As honeybee populations confront challenges from changing environmental conditions and resource availability, understanding these molecular responses is crucial for their effective management and conservation as essential pollinators. This study establishes a foundation for further investigations into the functional consequences of these molecular responses at the individual level and their broader implications for honeybee colony development and health.\n\nID: 42401664\nTitle: Evaluation of autophagy in neonatal rat glial cells in an in vitro model of hypoxic-ischemic injury.\nAbstract: The autophagy process is crucial for cell functioning, yet it is still understudied in glial cells during neurodevelopment. To address this, cultures of the main glial cell types in the central nervous system (CNS), including astrocytes, microglia, oligodendrocyte progenitors, and differentiating oligodendrocytes, were created to examine the impact of an in vitro hypoxia-ischemia (HI) model on autophagy. The HI insult was mimicked by applying temporal oxygen-glucose deprivation (OGD). Since neonatal hypoxic-ischemic insults primarily affect the brain's white matter, the study predominantly focused on oligodendrocytes at different stages of maturation: progenitor cells versus cells that express myelin components (e.g. MBP). The results show that the different glial fractions exhibit varying sensitivity to the applied conditions. Maturing oligodendrocytes were found to be more sensitive to OGD conditions than the progenitor fraction. The OGD procedure was proven to impact the expression of autophagy markers, indicating the activity of this process in response to injury. Western blot analysis of oligodendrocyte progenitor cells (OPCs) showed that the autophagy substrate marker p62 increased after six hours, which may suggest transient inhibition and subsequent activation of autophagy. To verify the involvement of autophagy in the differentiation of neonatal oligodendrocytes, the process was modulated using chloroquine (CQ) treatment. CQ is recognised as an inhibitor of autophagic flux because it disrupts lysosomal acidity and prevents the breakdown of autophagosomes. CQ treatment resulted in the accumulation of autophagosomes. The results suggest that abnormalities in the functioning of glial cells, particularly oligodendrocytes, in response to hypoxic-ischaemic (HI)-like conditions might be associated with altered autophagic flux in response to cellular stress. Transient alterations in autophagy were observed within 24\u00a0h of limiting oxygen and glucose supply, and these alterations may contribute to subsequent disorders in oligodendrocyte differentiation. This is recognised as one of the major issues in the pathogenesis of neonatal hypoxia-induced damage. Therefore, modulation of autophagy could be a promising therapeutic approach to prevent these adverse changes.\n\nID: 42401412\nTitle: Epstein-Barr virus downregulates breast cancer gene 1 to facilitate GPX4-dependent ferroptosis resistance and tumor growth of B-cell lymphoma.\nAbstract: Ferroptosis has emerged as a crucial mechanism in numerous pathological processes such as malignant development. Epstein-Barr virus (EBV) is associated with many malignancies such as B-cell lymphoma (B-CL). However, the role and mechanism of EBV in regulating ferroptosis to participate B-CL development remains poorly understood. Here, we displayed that the expression of breast cancer gene 1 (BRCA1) was downregulated in EBV-infected B-CL cells and tissues. EBV-encoded nuclear antigen 1 (EBNA1) was responsible for the BRCA1 downregulation. Moreover, the expression of BRCA1 was negatively related to that of glutathione peroxidase 4 (GPX4) in B-CL tissues. EBNA1 inhibited ferroptosis by inducing GPX4 expression via BRCA1 inhibition. Mechanistically, BRCA1 bound to GPX4 and promoted GPX4 degradation via the autophagy pathway, thus increasing the sensitivity of EBV-positive B-CL cells to ferroptosis. Furthermore, BRCA1 depletion suppressed ferroptosis in B-CL cells, and the knockdown of endogenous GPX4 in EBV-infected Daudi cells restored ferroptosis sensitivity and markedly suppressed xenograft tumor growth. The findings unveil a novel mechanism by which EBV inhibits ferroptosis for its contribution to the progression of B-CL, identifying a new pathway of BRCA1-mediated GPX4 destabilization. The results provide a new direction for the viral tumorigenicity and potential treatment targets of EBV-related B-CL.\n\nID: 42401409\nTitle: Sinomenine regulates the AKT/FOXO3/GLUL pathway to inhibit pulmonary fibroblast-to-myofibroblast transition via \u03b17nAChR against rheumatoid arthritis associated interstitial lung disease.\nAbstract: Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is a severe extra-articular manifestation with limited treatment options. Identifying anti-arthritic agents that concurrently protect against ILD is clinically significant. Sinomenine (SIN), a natural alkaloid used clinically to treat RA, shows potential anti-fibrotic activity, but its efficacy and mechanism in RA-ILD remain unclear. Here, integrative bioinformatic analyses identified ILD-associated signature characterized by upregulated CHRNA7 (encoding \u03b17nAChR) and downregulated GLUL, specifically in pulmonary fibroblasts and myofibroblasts, and GLUL was a crucial mediator between RA and ILD. In the adjuvant-induced arthritis (AIA) model with pulmonary inflammatory and fibrotic remodeling, the phenotype that recapitulates early-stage RA-ILD, pulmonary ACh and \u03b17nAChR expression were observed upregulated. SIN ameliorated arthritis and pulmonary lesions, suppressed pulmonary \u03b17nAChR signaling, inhibited AKT/FOXO3 activation, restored GLUL expression and improved autophagy-related changes in this model. Microscale thermophoresis (MST), molecular docking and molecular dynamics simulation supported a direct binding between SIN and \u03b17nAChR. In vitro, \u03b17nAChR activation with PNU-282987 promoted fibroblast-to-myofibroblast transition (FMT), whereas its genetic knockdown inhibited FMT, suppressed AKT/FOXO3 activation, and restored GLUL expression in TGF-\u03b2-stimulated MRC-5 cells. We confirmed direct FOXO3 binding to the GLUL promoter by ChIP-qPCR. SIN inhibited FMT and regulated the AKT/FOXO3/GLUL axis in an \u03b17nAChR-dependent manner. Pharmacological inhibition and siRNA-mediated knockdown of GLUL abolished SIN-mediated regulation of mTOR-autophagy signaling and FMT. Our findings identify the \u03b17nAChR/AKT/FOXO3/GLUL axis as a novel fibrotic driver and highlight SIN as a potential therapeutic candidate to inhibit RA-ILD by targeting this axis.\n\nID: 42401319\nTitle: Irisin and anxiety-like behaviors: Mechanistic integration of peripheral-central crosstalk, neuroinflammation and neural plasticity.\nAbstract: Anxiety-related disorders are highly prevalent and persistently difficult to treat, largely due to insufficient understanding of peripheral-central regulatory mechanisms governing emotional behaviors. Irisin, an exercise-dependent myokine, serves as a critical peripheral-to-central signaling mediator modulating brain function and anxiety-like behavioral phenotypes. This review systematically integrates current preclinical evidence illustrating how irisin regulates anxiety through multi-level neural mechanisms. Irisin suppresses microglial NF-\u03baB/STAT3-mediated neuroinflammation, enhances prefrontal-hippocampal synaptic plasticity via BDNF upregulation and AMPK/mTOR-related autophagy, and improves gut-brain axis homeostasis by stabilizing intestinal barrier integrity and reshaping microbial composition. Crucially, we propose a context-dependent therapeutic window model to reconcile contradictory pro-anxiogenic and anxiolytic findings across stress severity and pathological stages, resolving existing controversies in this field. We further summarize key unresolved limitations, including ambiguous central receptor identity, peripheral-central dissociation and sex-dependent heterogeneity. This work provides an integrated mechanistic framework linking muscular metabolic signals to affective circuit regulation, offering novel translational perspectives for anxiety behavioral modulation and targeted therapeutic development.\n\nID: 42401235\nTitle: Tanshinone IIA inhibits choroidal neovascularization and restores outer blood-retinal barrier function in Vldlr knockout mice.\nAbstract: Age-related macular degeneration (AMD) is a leading cause of vision loss, with its neovascular form (nAMD) primarily treated using anti-VEGF agents; however, therapeutic resistance and nonresponse remain major clinical challenges. Tanshinone IIA (TIIA), a multi-target bioactive compound derived from Salvia miltiorrhiza, has shown potential in retinal disease treatment. In this study, we investigated the therapeutic effects and underlying mechanisms of TIIA on choroidal neovascularization (CNV) using Vldlr knockout (Vldlr-/-) mice as an nAMD model. TIIA was administered intraperitoneally for 8 weeks, and CNV progression and vascular leakage were evaluated by OCT and FFA, while outer blood-retinal barrier (oBRB) integrity was assessed by immunofluorescence staining. Proteomics analysis combined with western blotting was used to explore the molecular mechanisms. Our results showed that TIIA significantly reduced CNV area and leakage, and restored oBRB integrity by upregulating tight junction proteins ZO-1 and Occludin in the RPE/choroid complex. Mechanistically, TIIA inhibited angiogenesis via suppression of the PLC\u03b3/ERK1/2 signaling pathway. In addition, proteomics analysis revealed enhanced cholesterol efflux, intermediate filament reorganization, and decreased autophagy-related proteins across the retina, RPE/choroid complex, and serum. Collectively, these findings demonstrate that TIIA alleviates nAMD pathology through multi-target mechanisms, including inhibition of angiogenesis, restoration of barrier function, metabolic reprogramming, and modulation of autophagy, highlighting its potential as an alternative therapeutic strategy for nAMD.\n\nID: 42401210\nTitle: Tapt1 deficiency in mice impairs pulmonary lipid homeostasis and normal postnatal respiration by targeting ABCA3 for autophagy-lysosomal degradation.\nAbstract: TAPT1, which encodes a highly conserved multi-pass transmembrane protein termed transmembrane anterior posterior transformation 1 (TAPT1), has been reported as a disease-causing gene, but its physiological role in mice remains to be elucidated. Using Tapt1 knockout and knock-in mice, we indicate that TAPT1 localizes to the endoplasmic reticulum and that Tapt1 deletion causes neonatal lethality due to atelectasis-induced respiratory distress. We further reveal that TAPT1 interacts with the ATP-binding cassette transporter A3 (ABCA3), thereby regulating autophagy-lysosomal degradation of ABCA3. ABCA3 insufficiency reduces surfactant lipids, leading to defective lamellar body formation and surfactant production. This study presents a hitherto unrecognized pathway for ABCA3 protein degradation. Our findings may advance the understanding of genetic determinants of neonatal respiratory distress syndrome, providing valuable insights into the treatment of lung surfactant disorders.\n\nID: 42401166\nTitle: Aloin suppresses cancer cell growth via autophagy-promoted NEDD8 de-NEDDylation to target GPX4 for ferroptosis induction.\nAbstract: Aloin (ALO), an anthraquinone derived from Aloe vera, exhibits antitumor activity; however, its precise mechanisms of action remain unclear. In this study, in silico molecular docking analysis first revealed that Aloin (ALO) bound effectively to ferroptosis-related proteins (SLC7A11, GPX4, ACSL4, and TFR1). Subsequently, in vitro ALO treatment triggered ferroptosis hallmarks in human cervical cancer cell line Hela and mouse colon cancer cell line MC38 at both transcriptional and protein levels-downregulating SLC7A11/GPX4, upregulating ACSL4/TFR1, with Fe2+/ROS accumulation, GSH depletion, and ferroptosis-specific mitochondrial cristae loss. Furtherly, ALO inhibited cancer cell proliferation, migration, and invasion, effects that were reversed by the ferroptosis inhibitor Ferrostatin-1. Concurrently, ALO induced autophagy, as evidenced by increased levels of LC3, LaminB1, and ULK1, decreased levels of P62, and TEM-visualized autophagosomes. Notably, the autophagy inhibitor chloroquine reversed ALO-induced ferroptosis, NEDD8 downregulation, and NEDP1 upregulation, linking ALO-induced autophagy to NEDD8 de-NEDDylation. Genetic and pharmacological perturbation of the NEDD8 pathway confirmed this: NEDD8 inhibition enhanced, while NEDP1 knockdown attenuated, ALO-induced ferroptosis. Co-immunoprecipitation and laser-scanning confocal microscope confirmed a direct NEDD8-GPX4 interaction diminished by ALO, positioning GPX4 as a key effector. In in vivo study, ALO effectively inhibited cancer cell growth in a murine colon carcinoma MC38 xenograft models, while exhibiting no obvious toxicity or side effects in mice. Moreover, ALO exhibited the same regulatory effects and trends on ferroptosis-related proteins in vivo as those in vitro. In summary, this study reveals a novel mechanism that ALO-induced autophagy promotes NEDD8 de-NEDDylation, driving ferroptosis via the NEDD8-GPX4 axis to suppress cancer cell growth.\n\nID: 42401103\nTitle: Single-cell spatial landscape of aggrephagy activity stratifies hepatocellular carcinoma neutrophils and delivers a 5-gene diagnostic panel for patient stratification.\nAbstract: Hepatocellular carcinoma (LIHC) features a complex tumor microenvironment (TME) where tumor-associated neutrophils (TANs) show significant plasticity. The role of aggrephagy-selective autophagy of protein aggregates-in shaping neutrophil heterogeneity and LIHC progression remains poorly understood. We integrated scRNA-seq (183,671 cells), spatial transcriptomics, and bulk datasets (TCGA, GSE39791). Neutrophils (n=12,547) were re-clustered into six subsets, and aggrephagy activity was quantified via UCell scores. Analysis included pseudotime trajectories, cell-cell communication, metabolic scoring, and machine-learning-based feature selection, followed by in vitro functional validation. Aggrephagy activity was significantly elevated in tumor tissues compared with adjacent normal tissues (P < 0.001) and showed strong cell-type specificity, with TANs among the most enriched populations. High-aggrephagy neutrophils exhibited an undifferentiated state, preferential tumor enrichment, and a positive correlation with transcriptomic risk scores. Trajectory analysis positioned these cells at an early differentiation branch and revealed dominant neutrophil-to-stroma signaling through the CCL3-CCR1, SPP1-CD44, and ANXA1-FPR1 axes. Metabolically, high-aggrephagy neutrophils displayed enhanced inflammatory and epithelial mesenchymal-transition programs alongside suppressed oxidative phosphorylation. Integrative network analysis identified a five-gene diagnostic panel (SQSTM1, WDFY3, DOCK4, CD177, LIMK2) with robust performance across bulk cohorts (AUC 0.83-0.91). Among these, LIMK2 marked a highly interactive neutrophil subset and functionally promoted tumor cell proliferation, survival, migration, and invasion in vitro. Aggrephagy is associated with a pro-tumorigenic, metabolically reprogrammed neutrophil state in LIHC. The LIMK2-centered gene panel provides a robust framework for subset identification and nominates candidate targets for future autophagy- and neutrophil-directed studies.\n\nID: 42401068\nTitle: Dihydroberberine regulates the ferroptosis-autophagy positive feedback loop in colorectal cancer by targeting PANX2.\nAbstract: Colorectal cancer (CRC) is one of the most common malignancies worldwide and remains a major clinical challenge, underscoring the urgent need for novel therapeutic targets and treatment strategies. Ferroptosis, a form of cell death triggered by iron-dependent lipid peroxidation, is emerging as a promising new anti-cancer therapeutic strategy. This study aims to identify a key target regulating the ferroptosis process in CRC, screen for small molecule modulators against this target, and elucidate their potential anti-tumor mechanisms. We developed a Drug Discovery Strategy for Targeted Ferroptosis Therapy Based on Bioinformatics-Machine Learning Integration for the Treatment of CRC (DDTF-BMLI-CRC), aiming to identify key ferroptosis regulators. The functional role of this factor in CRC and ferroptosis was validated through knockdown and overexpression techniques, establishing it as a potential therapeutic target. Subsequently, candidate compounds were screened from natural product and FDA databases using a dual-scoring model combining machine learning and deep learning. The direct binding of candidate compounds to target proteins was validated through molecular docking, molecular dynamics simulations, DARTS, CETSA, and SPR techniques. Finally, a series of in vitro and in vivo experiments were conducted to systematically evaluate their anti-tumor effects and potential mechanisms. PANX2 was identified as a key ferroptosis-suppressing gene in CRC. We discovered the natural small molecule dihydroberberine (dhBBR) to be a potent and direct inhibitor of the PANX2 protein. In vitro, dhBBR significantly inhibited the proliferation, migration, and invasion of CRC cells while inducing ferroptosis. In vivo, dhBBR effectively suppressed xenograft tumor growth. Mechanistic studies revealed that dhBBR-induced ferroptotic stress activates autophagy, which in turn promotes GPX4 degradation, thereby amplifying the ferroptotic effect and establishing a ferroptosis-autophagy positive feedback loop. Crucially, PANX2 knockdown largely abolished the additional anti-tumor effect of dhBBR, and dhBBR did not further suppress tumor growth beyond PANX2 knockdown alone. This study demonstrates that PANX2 knockdown suppresses CRC progression by inducing ferroptosis. Furthermore, we identified dhBBR for the first time as a PANX2-targeting small-molecule inhibitor. Our research reveals a novel therapeutic strategy targeting the PANX2-mediated ferroptosis-autophagy axis and provides a highly promising candidate compound for the treatment of CRC.\n\nID: 42401010\nTitle: COP9 signalosome 8 mediated autophagy drives proliferation, invasion, and metastasis in pancreatic ductal adenocarcinoma.\nAbstract: The present study aimed to explore the role of COP9 signalosome 8 (COPS8) as a novel molecule in pancreatic ductal adenocarcinoma (PDAC). A total of 9 genes were first identified by intersecting the differential genes of the GSE15471 and GSE62165 datasets with 248 Neddylation genes from the Reactome Pathway Database. The association between disease-free survival and the 9 genes in patients with PDAC was analyzed. Analysis using The Cancer Genome Atlas, Gene Expression Omnibus and Gene Expression Profiling Interactive Analysis databases revealed that COPS8 was highly expressed in patients with PDAC, and PDAC tissues exhibited significantly higher COPS8 expression levels compared to those found in paracancerous tissues. Finally, the above results were verified by cellular experiments, reverse transcription-quantitative PCR, Western blotting and immunohistochemistry. The mRNA expression levels of COPS8 were significantly elevated in the pancreatic cancer cell lines PANC-1and MIA PaCa-2 compared to those in HPNE normal pancreatic cells, and the protein expression levels of COPS8 were also significantly elevated in the pancreatic cancer cells PANC-1 and MIA PaCa-2. COPS8 protein was significantly increased in cancer tissues of patients with pancreatic cancer compared to paracancerous tissues. The proliferative, migratory and invasive abilities of PANC-1 and MIA PaCa-2\u202fcells were significantly reduced after knockdown of COPS8. The results showed that knockdown of COPS8 in PANC-1 and MIA PaCa-2\u202fcells decreased Microtubule-associated proteins 1A/1B light chain 3B (LC3\u2161/LC3\u2160), while Sequestosome 1 (P62/SQSTM1) expression was elevated. COPS8 may promote the proliferation, invasion, and metastasis of pancreatic cancer cells by regulating autophagy.\n\nID: 42400944\nTitle: Heteronemin, a Scalarane Sesterterpenoid, Activates Apoptosis and Non-Apoptotic Ferroptosis and Inhibits Cytoprotective Autophagy in Oral Cancer Cells.\nAbstract: Oral squamous cell carcinoma (OSCC) ranks 16th worldwide as the most common type of malignancy in head and neck cancer globally, and addressing it has been an ongoing but difficult pursuit, as treatment resistance is commonly reported. Hence, employing multiple cell death pathways is an emerging strategy in overcoming treatment resistance in OSCC. We investigate here the effect of heteronemin, a marine sesterterpenoid isolated from sponges, for its anti-cancer potential, hypothesizing that it can induce non-apoptotic cell death pathways to overcome apoptosis-resistant cells and elucidate the underlying mechanisms involved. Our results show that heteronemin significantly kills cancer cells via the induction of the intrinsic apoptotic pathway. It also triggers ferroptosis, down-regulating glutathione peroxidase 4 (GPX4) and upregulating markers of lipid peroxidation such as 4-hydroxynonenal and malondialdehyde. We demonstrate that increasing reactive oxygen species generation plays a central role in triggering these pathways. ensuring the death of the cancer cells despite a compensation attempt via inducing autophagy and modulating Nrf2. Our study is the first to demonstrate the complex but interesting role of heteronemin in killing OSCC cells: inducing apoptosis and switching to ferroptosis as the cells attempt to survive. It also inhibits protective autophagy, leaving OSCC cells incapable of protecting themselves from imminent death. This complex mechanism adds to the existing knowledge on the mechanism of heteronemin as a strong therapeutic compound to treat OSCC cells.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42400506\nTitle: Correction to \"Melatonin Antagonizes Cadmium-Induced Neurotoxicity By Activating the Transcription Factor Eb-Dependent Autophagy-Lysosome Machinery in Mouse Neuroblastoma Cells\".\nAbstract: \n\nID: 42400326\nTitle: Malformin A1-mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy.\nAbstract: Cytoskeletal proteins play a crucial role in providing mechanical support and regulating key cellular processes such as cell proliferation, migration, and invasion. Cytoskeletal damage has been increasingly regarded as a contributing factor in impairing these cellular processes in cancer. Moreover, induction of cell death pathways has been linked to cytoskeletal destabilization. However, the effect of cytoskeletal disruption on cell death mechanisms in ovarian cancer (OC) remains elusive. Several natural compounds have been demonstrated to initiate cytoskeletal destabilization as a mechanism to promote cell death. We have previously shown that one such natural compound derived from marine sources, Malformin A1 (MA1), exhibits high toxicity toward both cisplatin-sensitive (A2780S) and cisplatin-resistant (A2780CP) OC cell lines. Thus, here we evaluate the impact of cytoskeletal destabilization by MA1 treatment on OC cell death by analyzing the expression levels of apoptosis, autophagy, and DNA damage-related genes. Our findings show MA1 treatment significantly downregulated key cytoskeletal proteins while also decreasing the expression of pro-apoptotic markers, suggesting alternative cell death mechanisms. Autophagy-related analyses demonstrated enhanced LC3BI to LC3BII processing, indicating autophagy activation with elevated \u03b3-H2AX levels confirming substantial DNA damage in MA1-treated cells. Notably, MA1 was able to induce pyroptotic cell death, as evidenced by increased caspase-1 expression. Moreover, molecular docking analysis revealed that MA1 displayed the strongest binding affinity for vimentin, GAPDH, and \u03b2-tubulin, providing mechanistic insights into its ability to disrupt cytoskeletal integrity and induce nonapoptotic cell death through multiple pathways, highlighting MA1's potential as a promising therapeutic candidate.\n\nID: 42400323\nTitle: A PARK9 iPSC-Derived Dopaminergic Neuron Model Enables Drug Screening Targeting Autophagy-Lysosome Pathway Dysfunction in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disease characterized by dopaminergic neuronal degeneration in the substantia nigra, in which lysosomal dysfunction and impaired autophagy-lysosome pathway activity are increasingly recognized as important pathogenic mechanisms. However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.\n\nID: 42400065\nTitle: Astaxanthin attenuates CTX-induced premature ovarian failure by alleviating ovarian apoptosis and autophagy in vivo.\nAbstract: Cyclophosphamide (CTX) is a commonly used chemotherapeutic agent for breast cancer that frequently causes premature ovarian failure (POF), a clinical syndrome characterized by menstrual irregularities in women under the age of 40 years, accompanied by elevated serum follicle-stimulating hormone (FSH) and decreased estrogen levels. Astaxanthin (AS), a natural antioxidant, has been shown to exert various biological effects, including anti-aging and anti-inflammatory effects. However, further investigation into its anti-ovarian aging mechanism is warranted. Two-month-old female mice and CTX-induced POF model mice were used. Hematoxylin and eosin staining, immunohistochemical staining, TUNEL assays, Western blotting, and qPCR analyses were employed to evaluate ovarian function and related phenotypes after astaxanthin treatment. Subsequently, network pharmacology analysis was used to elucidated potential targets. Astaxanthin intervention significantly ameliorated estrous cycle disorder in POF mice and restored serum levels of anti-M\u00fcllerian hormone (AMH) and estradiol (E2). Meanwhile, astaxanthin markedly enhanced the ovarian reserve and suppressed CTX-induced apoptosis and autophagy. Mechanistically, astaxanthin was found to modulate the CYP19A1 expression, thereby enhancing ovarian function. This study elucidates the mechanism by which astaxanthin improves ovarian function through the CYP19A1, providing potential molecular targets and therapeutic strategies for the clinical treatment of POF.\n\nID: 42400028\nTitle: SERINC3 promotes osteogenic differentiation of BMSCs via IL-32/AMPK-mediated autophagy and mitochondrial energy metabolism.\nAbstract: SERINC3, a member of the serine incorporator protein family, is known for its roles in viral resistance and tumorigenesis, however, its function in osteogenesis remains unexplored. Lentivirus infection, alkaline Phosphatase/Alizarin Red S Staining, and RT-qPCR were used to evaluate the osteogenic differentiation of mesenchymal stem cells mediated by SERINC3. MicroCT, H&E, and Masson staining were performed to investigate the bone formation and bone defect repair via Serinc3 knockout (KO) mice and nude mice. RNA sequencing, Co-IP, Western blotting, and Seahorse energy metabolism analysis were performed to elucidate the regulatory mechanism of SERINC3. Here, we identify SERINC3 as a critical regulator of osteogenic differentiation of bone marrow-derived stem cells (BMSCs) and bone regeneration. SERINC3 expression was significantly upregulated during osteogenic differentiation of BMSCs and stem cells from human exfoliated deciduous teeth (SHED). Functional assays revealed that SERINC3 overexpression enhanced osteogenic differentiation, proliferation, and migration of MSCs, while Serinc3-KO impaired these processes and led to osteopenia in mice. In a calvarial defect model, Serinc3-KO mice exhibited 42% less bone volume (BV/TV) and 35% lower bone mineral density (BMD), whereas SERINC3-overexpressing BMSCs significantly improved bone repair. Mechanistically, RNA sequencing and pathway analysis revealed that SERINC3 interacts with IL32 to activate the AMPK-ULK1-autophagy axis, thereby promoting osteogenesis. Additionally, SERINC3 enhanced mitochondrial energy metabolism by upregulating tricarboxylic acid cycle enzymes (ACO1, DLAT, SDHA) and increasing oxygen consumption rates. Rescue experiments confirmed that AMPK inhibition or autophagy blockade abolished SERINC3-mediated osteogenic effects, whereas mitochondrial electron transport chain activators restored osteogenesis in SERINC3-knockdown cells. In summary, this study identifies SERINC3 as a novel regulator of bone formation that orchestrates osteogenesis through IL32-AMPK-autophagy signaling axis and mitochondrial metabolism. These findings highlight SERINC3 as a potential therapeutic target for enhancing bone regeneration and treating skeletal defects.\n\nID: 42399999\nTitle: Immune-reproductive cross\u00a0talk in mosquitoes: molecular pathways and energy homeostasis.\nAbstract: In the field of global health, mosquito-borne infectious diseases (such as malaria, dengue fever, and Zika) remain serious public health concerns. Recent research has emphasized that mosquitoes must coordinate their reproductive output and immune defenses under limited energy and nutritional conditions, forming a tightly regulated trade-off. This process involves complex signaling pathways and stage-specific molecular mechanisms. Key factors, such as juvenile hormone (JH), 20-hydroxyecdysone (20E), autophagy pathways, immune-regulatory genes, and metal ions, can potentially influence this equilibrium state, thereby either promoting or inhibiting the occurrence and development of mosquito-borne infectious diseases. However, the exact mechanism underlying this regulation remains unclear. This review summarizes recent findings on how these components interact at the molecular and physiological levels, with the aim of developing a rational framework for identifying potential molecular targets and developing new strategies for vector control.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

This study aimed to develop an enzyme-responsive, fibrosis-targeted nanotherapeutic system capable of simultaneously delivering siRNA against progranulin (siPGRN) and quercetin (QT) to remodel the fibrotic microenvironment and effectively attenuate renal fibrosis. The TIMP-HDL-Nano@siPGRN&QT nanoparticles prepared in this study exhibit uniform nanoscale size (~\u2009100\u00a0nm), high encapsulation efficiency, excellent stability, and favorable biocompatibility. The MMP9-responsive modification significantly enhanced renal accumulation and fibrotic lesion targeting in vivo. Treatment with TIMP-HDL-Nano@siPGRN&QT markedly alleviated UUO-induced renal injury, apoptosis, and fibrosis, outperforming free drug. Transcriptomic and mechanistic analyses revealed that the therapeutic effects were mediated through disruption of the PGRN-PPAR\u03b1 interaction, restoration of PPAR\u03b1 signaling, and subsequent inhibition of NF-\u03baB-driven inflammatory pathways. Furthermore, the nanoparticles suppressed pro-inflammatory M1 macrophage polarization and promoted M2 polarization in a PPAR\u03b1-dependent manner. This study demonstrates that TIMP-HDL-Nano@siPGRN&QT enables efficient, targeted co-delivery of siRNA and small-molecule therapeutics to fibrotic kidneys. By remodeling the fibrotic immune microenvironment through the PGRN-PPAR\u03b1-NF-\u03baB axis, this nanoplatform provides a potent and mechanistically defined strategy for the treatment of renal fibrosis and offers translational potential for other inflammation-driven fibrotic diseases.\n --- END ACTUAL ABSTRACT FOR 42399921 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"It was found that Q and EC significantly increased the expression levels of autophagy-related genes\" (Source: 40351085)\n- \"Q3G and rutin may modulate SGLT-related pathways through intestinal SGLT1 interaction\" (Source: 42399973)\n- \"Pretreatment of OPCs with autophagy inhibitor bafilomycin A1 inhibited quercetin-mediated ferritinophagy and ferroptosis\" (Source: 39946767)\n- \"In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI\" (Source: 42400341)\n- \"The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC\" (Source: 42385849)\n- \"hUC-MSC-exo-Que significantly attenuates liver fibrosis in a carbon tetrachloride-induced mouse model, outperforming free quercetin at the equivalent dose.\" (Source: 42395946)\n- \"Compounds like quercetin, ursolic acid, and berberine have demonstrated significant activity in various preclinical models.\" (Source: 42401246)\n- \"TIIA inhibited angiogenesis via suppression of the PLC\u03b3/ERK1/2 signaling pathway.\" (Source: 42401235)\n- \"High-aggrephagy neutrophils exhibited an undifferentiated state, preferential tumor enrichment, and a positive correlation with transcriptomic risk scores.\" (Source: 42401103)\n- \"Mechanistic studies revealed that dhBBR-induced ferroptotic stress activates autophagy, which in turn promotes GPX4 degradation\" (Source: 42401068)\n- \"It also inhibits protective autophagy, leaving OSCC cells incapable of protecting themselves from imminent death.\" (Source: 42400944)\n- \"Our findings show MA1 treatment significantly downregulated key cytoskeletal proteins while also decreasing the expression of pro-apoptotic markers\" (Source: 42400326)\n- \"A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation\" (Source: 42400323)\n- \"Astaxanthin intervention significantly ameliorated estrous cycle disorder in POF mice and restored serum levels of anti-M\u00fcllerian hormone (AMH) and estradiol (E2).\" (Source: 42400065)\n- \"SERINC3 interacts with IL32 to activate the AMPK-ULK1-autophagy axis, thereby promoting osteogenesis.\" (Source: 42400028)\n- \"Mir452 significantly promotes protective autophagy in septic AKI by suppressing the APAF1-CASP9 axis\" (Source: 42402931)\n- \"We measured the beneficial effects of metformin (MET), an anti-diabetic drug, on misfolded protein as assessed by thioflavin (ThT) spectroscopy and improved autophagy\" (Source: 39562539)\n- \"In vitro studies consistently demonstrate that these compounds exert anticancer effects by modulating multiple pathways, including PI3K/AKT/mTOR, Wnt/\u03b2-catenin, STAT3, and MAPK/ERK\" (Source: 42405384)\n- \"Natural fermentation is conducive to the production of flavonoid compositions such as kaempferol and quercetin\" (Source: 42392709)\n\n\nINSTRUCTION: Study the actual abstracts provided.

"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]\nDoes existing in vitro data show that Quercetin-induced autophagy can successfully degrade DUX4 or its downstream misfolded proteins?\n\nThe provided literature contains no evidence that Quercetin-induced autophagy degrades DUX4 or its downstream products. While Quercetin is extensively cited as an autophagy modulator that promotes the clearance of various toxic aggregates (such as amyloid-beta or alpha-synuclein), DUX4 is not mentioned in the provided literature. Consequently, there is insufficient evidence to support or refute this claim.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific literature was evaluated to determine if Quercetin-induced autophagy modulates DUX4-related proteotoxicity. The claim is currently unsupported by the source material.\n\n### [INTRODUCTION & JUSTIFICATION]\nQuercetin functions as a potent natural product capable of modulating autophagic flux across diverse experimental models, including neurodegenerative diseases and metabolic disorders. Its role in autophagy typically involves the activation of pathways such as AMPK or the inhibition of specific autophagic suppressors. For instance, in models of Alzheimer\u2019s disease and ferritinophagy, Quercetin promotes the clearance of aggregated proteins. However, the specific protein DUX4, which is associated with facioscapulohumeral muscular dystrophy, is absent from the provided evidence set. Therefore, any functional link between Quercetin, autophagy, and DUX4 remains a knowledge gap.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Quercetin acts as a multi-target modulator that enhances autophagy to combat misfolded protein accumulation in neurodegeneration.\n* The interaction between Quercetin and autophagy is highly context-dependent, sometimes acting as an activator and sometimes as an inhibitor (e.g., in ferritinophagy).\n* Nanomicelle-based delivery of Quercetin significantly improves its systemic bioavailability and therapeutic potential compared to free Quercetin.\n* Quercetin suppresses NLRP3 inflammasome activation by modulating upstream oxidative stress and mitochondrial signaling pathways.\n* Autophagy-lysosomal pathway modulation via Quercetin represents a promising strategy for treating protein-aggregation diseases.\n* There is no mention of DUX4 in the entire provided corpus of 50+ research abstracts.\n* Quercetin's therapeutic efficacy is often limited by its poor pharmacokinetic profile, necessitating advanced nanocarrier design.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"39113571": "ID: 39113571\nTitle: Pharmacological inhibition of USP14 delays proteostasis-associated aging in a proteasome-dependent but foxo-independent manner.\nAbstract: Aging is often accompanied by a decline in proteostasis, manifested as an increased propensity for misfolded protein aggregates, which are prevented by protein quality control systems, such as the ubiquitin-proteasome system (UPS) and macroautophagy/autophagy. Although the role of the UPS and autophagy in slowing age-induced proteostasis decline has been elucidated, limited information is available on how these pathways can be activated in a collaborative manner to delay proteostasis-associated aging. Here, we show that activation of the UPS via the pharmacological inhibition of USP14 (ubiquitin specific peptidase 14) using IU1 improves proteostasis and autophagy decline caused by aging or proteostatic stress in Drosophila and human cells. Treatment with IU1 not only alleviated the aggregation of polyubiquitinated proteins in aging Drosophila flight muscles but also extended the fly lifespan with enhanced locomotive activity via simultaneous activation of the UPS and autophagy. Interestingly, the effect of this drug disappeared when proteasomal activity was inhibited, but was evident upon proteostasis disruption by foxo mutation. Overall, our findings shed light on potential strategies to efficiently ameliorate age-associated pathologies associated with perturbed proteostasis.Abbreviations: AAAs: amino acid analogs; foxo: forkhead box, sub-group O; IFMs: indirect flight muscles; UPS: ubiquitin-proteasome system; USP14: ubiquitin specific peptidase 14.",
"39454200": "ID: 39454200\nTitle: Role of Autophagy in Myocardial Remodeling After Myocardial Infarction.\nAbstract: Autophagy is the process of reusing the body's senescent and damaged cell components, which can be regarded as the cellular circulatory system. There are 3 distinct forms of autophagy: macroautophagy, microautophagy, and chaperone-mediated autophagy. In the heart, autophagy is regulated mainly through mitophagy because of the metabolic changes of cardiomyocytes caused by ischemia and hypoxia. Myocardial remodeling is characterized by gradual heart enlargement, cardiac dysfunction, and extraordinary molecular changes. Cardiac remodeling after myocardial infarction is almost inevitable, which is the leading cause of heart failure. Autophagy has a protective effect on myocardial remodeling improvement. Autophagy can minimize cardiac remodeling by preventing misfolded protein accumulation and oxidative stress. This review summarizes the nestest molecular mechanisms of autophagy and myocardial remodeling, the protective effects, and the new target of autophagy medicine in cardiac remodeling. The future development and challenges of autophagy in heart disease are also summarized.",

The mechanism by which host proteins are involved in the above process remains largely unknown. The present study found that porcine reproductive and respiratory syndrome virus (PRRSV) infection promoted the degradation of intracellular ubiquitinated protein aggregates via activating autophagy. The host cell E3 ligase tripartite motif-containing (TRIM)25 promoted the recruitment and aggregation of polyubiquitinated proteins and impeded their degradation caused by PRRSV. TRIM25 interacted with ubiquitinated aggregates and was part of the aggregates complex. Next, the present study investigated the mechanisms by which TRIM25 inhibited the degradation of protein aggregates, and it was found that TRIM25 interacted with both Kelch-like ECH-associated protein 1 (KEAP1) and nuclear factor E2-related factor 2 (Nrf2), facilitated the nuclear translocation of Nrf2 by targeting KEAP1 for K48-linked ubiquitination and proteasome degradation, and activated Nrf2-mediated p62 expression. Further studies indicated that TRIM25 interacted with p62 and promoted its K63-linked ubiquitination via its E3 ligase activity and thus caused impairment of its oligomerization, aggregation, and recruitment for the autophagic protein LC3, leading to the suppression of autophagy activation. Besides, TRIM25 also suppressed the p62-mediated recruitment of ubiquitinated aggregates. Activation of autophagy decreased the accumulation of protein aggregates caused by TRIM25 overexpression, and inhibition of autophagy decreased the degradation of protein aggregates caused by TRIM25 knockdown. The current results also showed that TRIM25 inhibited PRRSV replication by inhibiting the KEAP1-Nrf2-p62 axis-mediated autophagy. Taken together, the present findings showed that the PRRSV replication restriction factor TRIM25 inhibited the degradation of ubiquitinated protein aggregates during viral infection by suppressing p62-mediated autophagy.IMPORTANCESequestration of protein aggregates and their subsequent degradation prevents proteostasis imbalance and cytotoxicity. The mechanisms controlling the turnover of protein aggregates during viral infection are mostly unknown. The present study found that porcine reproductive and respiratory syndrome virus (PRRSV) infection promoted the autophagic degradation of ubiquitinated protein aggregates, whereas tripartite motif-containing (TRIM)25 reversed this process. It was also found that TRIM25 promoted the expression of p62 by activating the Kelch-like ECH-associated protein 1 (KEAP1) and nuclear factor E2-related factor 2 (Nrf2) pathway and simultaneously prevented the oligomerization of p62 by promoting its K63-linked ubiquitination, thus suppressing its recruitment of the autophagic adaptor protein LC3 and ubiquitinated aggregates, leading to the inhibition of PRRSV-induced autophagy activation and the autophagic degradation of protein aggregates. The present study identified a new mechanism of protein aggregate turnover during viral infection and provided new insights for understanding the pathogenic mechanism of PRRSV.",
"39551160": "ID: 39551160\nTitle: Targeted protein degradation: expanding the technology to facilitate the clearance of neurotoxic proteins in neurodegenerative diseases.\nAbstract: In neurodegenerative diseases (NDDs), disruptions in protein homeostasis hinder the clearance of misfolded proteins, causing the formation of misfolded protein oligomers and multimers. The accumulation of these abnormal proteins results in the onset and progression of NDDs. Removal of non-native protein is essential for cell to maintain proteostasis. In recent years, targeted protein degradation (TPD) technologies have become a novel means of treating NDDs by removing misfolded proteins through the intracellular protein quality control system. The TPD strategy includes the participation of two primary pathways, namely the ubiquitin-proteasome pathway (for instance, PROTAC, molecular glue and hydrophobic tag), and the autophagy-lysosome pathway (such as LYTAC, AUTAC and ATTEC). In this review, we systematically present the mechanisms of various TPD strategies employed for neurotoxic protein degradation in NDDs. The article provides an overview of the design, in vitro and in vivo anti-NDD activities and pharmacokinetic properties of these small-molecular degraders. Finally, the advantages, challenges and perspectives of these TPD technologies in NDDs therapy are discussed, providing ideas for further development of small molecule degraders in the realm of NDDs.",
"39562539": "ID: 39562539\nTitle: Advanced glycation end-products accelerate amyloid deposits in adipocyte's lipid droplets.\nAbstract: Adipose tissue dysfunction is central to insulin resistance, and the emergence of type 2 diabetes (T2D) is associated with elevated levels of carbonyl metabolites from glucose metabolism. In this study, using methylglyoxal (MGO) and glycolaldehyde (GAD) carbonyl metabolites induced protein glycation, leading to misfolding and \u03b2-sheet formation and generation of advanced glycation end products (AGEs). The formed AGEs compromise adipocytes activity. Microscopic and spectroscopic assays were used to examine the impact of MGO and GAD on lipid droplet-associated proteins. The results provide information about how these conditions lead to the appearance of glycated and amyloidogenic proteins formation that hinders metabolism and autophagy in adipocytes. We measured the beneficial effects of metformin (MET), an anti-diabetic drug, on misfolded protein as assessed by thioflavin (ThT) spectroscopy and improved autophagy, determined by LC3 staining. In vitro findings were complemented by in vivo analysis of white adipose tissue (WAT), where lipid droplet-associated \u03b2-amyloid deposits were predominantly linked to adipose triglyceride lipase (ATGL), a lipid droplet protein. Bioinformatics, imaging, biochemical and MS/MS methods affirm ATGL's glycation and its role in \u03b2-sheet secondary structure formation. Our results highlighted the pronounced presence of amyloidogenic proteins in adipocytes treated with carbonyl compounds, potentially reshaping our understanding of adipocyte altered activity in the context of T2D. This in-depth exploration offers novel perspectives on related pathophysiology and underscores the potential of adipocytes as pivotal therapeutic targets, bridging T2D, amyloidosis, protein glycation, and adipocyte malfunction.",
"39596274": "ID: 39596274\nTitle: Manganese Exposure Enhances the Release of Misfolded \u03b1-Synuclein via Exosomes by Impairing Endosomal Trafficking and Protein Degradation Mechanisms.\nAbstract: Excessive exposure to manganese (Mn) increases the risk of chronic neurological diseases, including Parkinson's disease (PD) and other related Parkinsonisms. Aggregated \u03b1-synuclein (\u03b1Syn), a hallmark of PD, can spread to neighboring cells by exosomal release from neurons. We previously discovered that Mn enhances its spread, triggering neuroinflammatory and neurodegenerative processes. To better understand the Mn-induced release of exosomal \u03b1Syn, we examined the effect of Mn on endosomal trafficking and misfolded protein degradation. Exposing MN9D dopaminergic neuronal cells stably expressing human wild-type (WT) \u03b1Syn to 300 \u03bcM Mn for 24 h significantly suppressed protein and mRNA expression of Rab11a, thereby downregulating endosomal recycling, forcing late endosomes to mature into multivesicular bodies (MVBs). Ectopic expression of WT Rab11a significantly mitigated exosome release, whereas ectopic mutant Rab11a (S25N) increased it. Our in vitro and in vivo studies reveal that Mn exposure upregulated (1) mRNA and protein levels of endosomal Rab27a, which mediates the fusion of MVBs with the plasma membrane; and (2) expression of the autophagosomal markers Beclin-1 and p62, but downregulated the lysosomal marker LAMP2, thereby impairing autophagolysosome formation as confirmed by LysoTracker, cathepsin, and acridine orange assays. Our novel findings demonstrate that Mn promotes the exosomal release of misfolded \u03b1Syn by impairing endosomal trafficking and protein degradation.",
"39617269": "ID: 39617269\nTitle: Quiescent cells maintain active degradation-mediated protein quality control requiring proteasome, autophagy, and nucleus-vacuole junctions.\nAbstract: Many cells spend a major part of their life in quiescence, a reversible state characterized by a distinct cellular organization and metabolism. In glucose-depleted quiescent yeast cells, there is a metabolic shift from glycolysis to mitochondrial respiration, and a large fraction of proteasomes are reorganized into cytoplasmic granules containing disassembled particles. Given these changes, the operation of protein quality control (PQC) in quiescent cells, in particular the reliance on degradation-mediated PQC and the specific pathways involved, remains unclear. By examining model misfolded proteins expressed in glucose-depleted quiescent yeast cells, we found that misfolded proteins are targeted for selective degradation requiring functional 26S proteasomes. This indicates that a significant pool of proteasomes remains active in degrading quality control substrates. Misfolded proteins were degraded in a manner dependent on the E3 ubiquitin ligases Ubr1 and San1, with Ubr1 playing a dominant role. In contrast to exponentially growing cells, the efficient clearance of certain misfolded proteins additionally required intact nucleus-vacuole junctions (NVJ) and Cue5-independent selective autophagy. Our findings suggest that proteasome activity, autophagy, and NVJ-dependent degradation operate in parallel. Together, the data demonstrate that quiescent cells maintain active PQC that relies primarily on selective protein degradation. The necessity of multiple degradation pathways for the removal of misfolded proteins during quiescence underscores the importance of misfolded protein clearance in this cellular state.",
"39743298": "ID: 39743298\nTitle: Autophagy receptor-inspired chimeras: a novel approach to facilitate the removal of protein aggregates and organelle by autophagy degradation.\nAbstract: Neurodegenerative diseases (NDDs), mainly including Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), and Alzheimer's disease (AD), are sporadic and rare genetic disorders of the central nervous system. A key feature of these conditions is the slow accumulation of misfolded protein deposits in brain neurons, the excessive aggregation of which leads to neurotoxicity and further disorders of the nervous system.",
"39842372": "ID: 39842372\nTitle: Quercetin inhibits platelet activation and ER-stress mediated autophagy in response to extracellular histone.\nAbstract: Cellular histones are DNA-binding nuclear proteins involved in chromatin remodelling and regulation of gene expression. However, extracellular histones act as damage-associated molecular patterns (DAMPs) and contribute to multiorgan damage in conditions with sepsis and diseases with acute critical illnesses. Alongside, histones are associated with thrombocytopenia due to dysfunctional platelets that regulate hemostasis and thrombosis. There is no drug available to prevent histone-induced platelet toxicity. Therefore, we for the first time examined quercetin (QUE) as a novel therapeutic to protect histone-induced platelet toxicity. To delineate how histones induce platelet toxicity and investigate the protective efficacy of quercetin (QUE), a natural dietary phytochemical. Histone-treated platelets were evaluated for platelet aggregation/activation markers, various autophagy-related signaling proteins, and cytotoxicity in vitro. For the inhibition study, QUE and other standard inhibitors were pre-treated before stimulation with histones. Further, we injected histones into mice in the presence or absence of QUE and evaluated the tail bleeding, lung toxicity, and circulatory platelet stress markers. Additionally, QUE-treated mice were challenged for histone-primed Collagen-epinephrine-induced pulmonary thromboembolism. Extracellular histones induce platelet activation and aggregation by interacting with sialic acid in TLR1/2 or TLR4. Also, we have demonstrated for the first time that histones induce ER stress-mediated autophagy in platelets. QUE inhibited histone-induced platelet activation, aggregation, and ER-stress-mediated autophagy in response to histone treatment. Ex vivo experiments indicate that oral administration of QUE can safeguard platelets while concurrently mitigating their response to histone stimulation. In addition, quercetin increased the survival rates of histone-primed, collagen-epinephrine-induced acute pulmonary thromboembolism in mice. In summary, this study demonstrated the beneficial effect of QUE in protecting platelets with possible implications for addressing histone-accelerated pathologies.",
"39920690": "ID: 39920690\nTitle: uN2CpolyG-mediated p65 nuclear sequestration suppresses the NF-\u03baB-NLRP3 pathway in neuronal intranuclear inclusion disease.\nAbstract: Neuronal intranuclear inclusion disease (NIID) is genetically linked to CGG repeat expansion in the 5'-untranslated region of the NOTCH2NLC gene, with nascent polyglycine-containing protein (uN2CpolyG) identified as a primary pathogenic factor. Emerging clinical evidence suggests that inflammation contributes to NIID pathogenesis, yet the underlying molecular mechanisms remain elusive. This study aimed to elucidate the molecular interaction between uN2CpolyG and the NF-\u03baB-NLRP3 pathway. Single-cell RNA sequencing was conducted on the skin tissues of NIID patients to assess changes in the expression of genes involved in inflammatory pathways. Cell models (HEK-293T and U87-MG) transfected with CGG9/69/100 expansion vectors were used to investigate alterations in the NF-\u03baB-NLRP3-autophagy pathway. Additionally, the therapeutic potential of NF-\u03baB activators was evaluated in a Drosophila model with a CGG expansion knock-in. Single-cell sequencing revealed a significant reduction in the expression of NFKBIA, encoding NF-\u03baB inhibitor alpha (IkBa), which facilitates the nuclear translocation of p65, a key NF-\u03baB component. uN2CpolyG directly interacted with and sequestered p65 in nuclear inclusions, leading to reduced phosphorylated p65 (p-p65) levels. This sequestration significantly downregulated the NF-\u03baB-NLRP3 pathway, impairing autophagy, as indicated by decreased LC3II/LC3I ratios. Treatment of CGG100 cells with lipopolysaccharide (LPS) significantly increased p-p65, NLRP3, and LC3II/LC3I levels while reducing insoluble uN2CpolyG levels and intranuclear inclusions. In the Drosophila knock-in model, LPS significantly reduced the number of intranuclear inclusions and improved phenotypic manifestations. This study revealed that uN2CpolyG directly interacts with and sequesters p65, thereby inhibiting the NF-\u03baB-NLRP3 pathway and impairing autophagy. This mechanism highlights a novel therapeutic target for NIID and provides potentially broader insights into similar mechanisms in other neurodegenerative diseases characterized by misfolded protein aggregates.",
"39946767": "ID: 39946767\nTitle: Quercetin inhibits oligodendrocytes ferroptosis by blocking NCOA4-mediated ferritinophagy.\nAbstract: Ferritinophagy is a specific type of autophagy that maintains intracellular iron metabolic homeostasis by targeting ferritin, one of the major forms of iron storage in the human body. Previous research has demonstrated that quercetin prevents the ferroptosis of oligodendrocyte progenitor cells (OPCs) by inhibiting the Id2/transferrin pathway. Given the ability of quercetin to suppress autophagy in spinal cord injury (SCI), this study aimed to investigate whether quercetin prevents ferroptosis in an autophagy-dependent manner. In erastin-treated OPCs, quercetin significantly upregulated the protein level of ferritin heavy chain (FTH) and markedly reduced its colocalization with LysoTracker, an indicator of lysosome aggregation. Quercetin significantly reduced the ferrous iron levels, the LC3II/LC3I ratio, and the number of LC3 puncta in OPCs, whereas it increased the level of sequestosome 1 (P62) in erastin-treated OPCs. Pretreatment of OPCs with autophagy inhibitor bafilomycin A1 inhibited quercetin-mediated ferritinophagy and ferroptosis, whereas pretreatment with autophagy activator rapamycin reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, as evidenced by reduced protein levels of ferritin heavy chain and p62, as well as increased protein levels of LC3II/LC3I and prostaglandin-endoperoxide synthase 2 (PTGS2). Compared with the erastin and quercetin treated OPCs, increased rerrous iron, lipid peroxidation production, and decreased GSH content, as well as shrunken mitochondria, were observed in OPCs treated with a combination of erastin, quercetin, and rapamycin. In vivo, quercetin significantly downregulated the nuclear receptor coactivator 4 (NCOA4) and PTGS2 protein expression, as well as the LC3II/LC3I ratio. Besides that, quercetin reduced the MDA level and the colocalization of FTH with NCOA4 in spinal cord tissues. Mechanistically, NCOA4 reversed the effect of quercetin on ferritinophagy and ferroptosis of OPCs, whereas mutation of Y71 to alanine only slightly reversed the above effect. In conclusion, our findings revealed that quercetin inhibits OPCs ferroptosis by blocking NCOA4-mediated ferritinophagy. Quercetin and ferritinophagy may be potential therapeutic agents for SCI.",
"40047433": "ID: 40047433\nTitle: Targeted Degradation Technology Based on the Autophagy-Lysosomal Pathway: A Promising Strategy for Treating Preeclampsia.\nAbstract: In recent years, targeted protein degradation (TPD) strategies leveraging the autophagy-lysosomal pathway (ALP) have transcended the limitations of conventional drug molecules, emerging as a highly promising approach for selectively eliminating disease-related proteins via the cell's intrinsic degradation machinery. These TPD methods, such as autophagosome-tethering compounds (ATTEC), autophagy-targeting chimera (AUTAC), AUTOphagy-TArgeting chimera (AUTOTAC), and chaperone-mediated autophagy (CMA) targeting chimera, exhibit efficacy in degrading misfolded protein aggregates associated with neurodegenerative disorders. Moreover, the excessive accumulation of misfolded proteins or protein complexes in the placenta has been identified as a significant contributor to preeclampsia (PE). Given the lack of effective treatments for PE, the application of autophagy-mediated TPD technology presents a novel therapeutic avenue. This review draws parallels between misfolded protein aggregates in neurodegenerative diseases and placenta-derived PE, integrating a substantial number of full-text studies. By harnessing TPD technologies grounded in the ALP, these autophagic degraders offer a pioneering approach for targeted therapy in PE by dismantling potential targets. Presently, there is limited exploration of ALP technology for identifying target proteins in the placenta. Nonetheless, we have proposed several potential target proteins, laying the groundwork for future therapeutic endeavors.",
"40069115": "ID: 40069115\nTitle: Self-Assembly of Short Peptides Activates Specific ER-Phagy and Induces Pyroptosis for Enhanced Tumor Immunotherapy.\nAbstract: Developing specific endoplasmic reticulum-autophagy (ER-phagy) inducers is highly desirable for discovering new ER-phagy receptors and elucidating the detailed ER-phagy mechanism and potential cancer immunotherapy. However, most of the current ER-phagy-inducing methods cause nonselective autophagy of other organelles. In this work, we report the design and synthesis of simple and stable short peptides (D-FFxFFs) that could specifically trigger ER-phagy, which further induces pyroptosis and activates the immune response against tumor cells. D-FFxFFs locate preferentially in ER and readily self-assemble to form nanosized misfolded protein mimics, which lead to distinct upregulation of dedicated ER-phagy receptors with no obvious autophagy of other organelles. Significant unfolded protein response (UPR) is activated via IRE1-JNK and PERK-ATF4 pathways. Interestingly, the persistent ER-phagy triggers ER Ca2+ release and a surge in mitochondrial Ca2+ levels, resulting in GSDMD-mediated pyroptosis other than apoptosis. The ER-phagy induces pyroptosis and activates a distinct antitumor immune response without evolving the acquired drug resistance. This work not only provides a powerful tool for investigating the mechanism and function of ER-phagy but also offers an appealing strategy for anticancer immunotherapy.",
"40133256": "ID: 40133256\nTitle: The ER-phagy receptor FAM134B is targeted by Salmonella Typhimurium to promote infection.\nAbstract: Macroautophagy/autophagy is a key catabolic-recycling pathway that can selectively target damaged organelles or invading pathogens for degradation. The selective autophagic degradation of the endoplasmic reticulum (hereafter referred to as ER-phagy) is a homeostatic mechanism, controlling ER size, the removal of misfolded protein aggregates, and organelle damage. ER-phagy can also be stimulated by pathogen infection. However, the link between ER-phagy and bacterial infection remains poorly understood, as are the mechanisms evolved by pathogens to escape the effects of ER-phagy. Here, we show that Salmonella enterica serovar Typhimurium inhibits ER-phagy by targeting the ER-phagy receptor FAM134B, leading to a pronounced increase in Salmonella burden after invasion. Salmonella prevents FAM134B oligomerization, which is required for efficient ER-phagy. FAM134B knock-out raises intracellular Salmonella number, while FAM134B activation reduces Salmonella burden. Additionally, we found that Salmonella targets FAM134B through the bacterial effector SopF to enhance intracellular survival through ER-phagy inhibition. Furthermore, FAM134B knock-out mice infected with Salmonella presented severe intestinal damage and increased bacterial burden. These results provide mechanistic insight into the interplay between ER-phagy and bacterial infection, highlighting a key role for FAM134B in innate immunity.",
"40332143": "ID: 40332143\nTitle: p.Phe508del-CFTR Trafficking: A Protein Quality Control Perspective Through UPR, UPS, and Autophagy.\nAbstract: Cystic fibrosis (CF) is a genetic disease due to mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The most frequent mutation (p.Phe508del) results in a misfolded protein (p.Phe508del-CFTR) with an altered transport to the membrane of the cells via the conventional protein secretion (CPS) pathway. Nevertheless, it can use unconventional protein secretion (UPS). Indeed, p.Phe508del-CFTR forms a complex with GRASP55 to assist its direct trafficking from the endoplasmic reticulum to the plasma membrane. While GRASP55 is a key player of UPS, it is also a key player of stress-induced autophagy. In parallel, the unfolded protein response (UPR), which is activated in the presence of misfolded proteins, is tightly linked to UPS and autophagy through the key effectors IRE1, PERK, and ATF6. A better understanding of how UPS, UPR, and stress-induced autophagy interact to manage protein trafficking in CF and other conditions could lead to novel therapeutic strategies. By enhancing or modulating these pathways, it may be possible to increase p.Phe508del-CFTR surface expression. In summary, this review highlights the critical roles of UPS- and UPR-induced autophagy in managing protein transport, offering new perspectives for therapeutic approaches.",
"40351085": "ID: 40351085\nTitle: Neuroprotective Potential of the Flavonoids Quercetin and Epicatechin in a C. elegans Tauopathy Model.\nAbstract: The prevalence of cognitive disorders such as Alzheimer's disease (AD) is increasing due to the global rise in longevity. The accumulation of amyloid \u03b2 (A\u03b2) deposits and hyperphosphorylated Tau protein (p-Tau) are considered the main hallmarks of AD. A growing body of evidence suggests that the regular intake of flavonoid-rich foods could reduce the risk of developing AD or mitigate its progression. This study explores the potential of quercetin (Q) and epicatechin (EC) as effective molecules against AD-like pathology, using the Caenorhabditis elegans BR5270 strain, which expresses the pro-aggregant F3DK280 fragment of the human Tau protein. The results showed that after exposure to 150\u00a0\u00b5M of EC or Q, worms exhibited increased lifespan, improved chemotaxis, and delayed age-related decline in locomotion. To explore the molecular mechanisms involved, the expression of genes associated with the inhibition of p-Tau proteotoxicity were measured by RT-qPCR. It was found that Q and EC significantly increased the expression levels of autophagy-related genes and of a key gene for de novo synthesis of \u03b1- tubulin. EC and Q delay neurodegeneration in the C. elegans tauopathy model, suggesting their potential to reduce the risk of AD progression.",
"40415242": "ID: 40415242\nTitle: Endoplasmic reticulum tubule junctions are sites of autophagy.\nAbstract: Selective endoplasmic reticulum (ER) macroautophagy/autophagy, also called reticulophagy, is a disposal pathway that degrades ER domains. A major role of reticulophagy is the removal of ER domains that contain misfolded proteins resistant to ER-associated degradation (ERAD). Our studies have shown that RTN3L, the SEC24C-SEC23 COPII coat subcomplex, and the CUL3KLHL12 E3 ligase that ubiquitinates RTN3L targets ERAD-resistant misfolded protein condensates for degradation at ER-reticulophagy sites (ERPHS), autophagic sites that form at tubule junctions. Unexpectedly, we found that the Parkinson disease protein PINK1 regulates ER tubulation. Loss of PINK1 disrupts the formation of peripheral tubule junctions, and, as a consequence, reticulophagy is blocked and misfolded proteins accumulate in the ER. Overexpression of the ER tubulating domain of DNM1L/DRP1, a multifunctional PINK1 kinase substrate that localizes to ER-mitochondria contact sites, increases junctions and restores reticulophagy. Our findings show that PINK1 shapes the ER to target misfolded proteins for RTN3L-SEC24C-mediated macroreticulophagy at defined ER sites, peripheral tubule junctions.",
"40678709": "ID: 40678709\nTitle: Chinese medicine monomers for hepatocellular carcinoma: New ideas related to autophagy.\nAbstract: Hepatocellular carcinoma (HCC) represents the most prevalent form of primary liver cancer, characterized by high mortality rates, frequent recurrence and metastasis, poor clinical prognosis, and a complex pathogenesis with limited therapeutic options. Autophagy plays a pivotal role in the immune response and functions as a lysosome-mediated degradation mechanism essential for recycling cellular components and eliminating aggregated proteins, damaged organelles, and invasive pathogens, thereby maintaining cellular function and dynamic homeostasis. Additionally, autophagy regulates several critical proteins and signaling pathways, including mammalian target of the rapamycin (mTOR), Beclin-1, the phosphatidylinositol 3-kinase/protein kinase B/mTOR signaling pathway, the Hippo/yes-associated protein signaling pathway, and the Janus kinase/signal transducer of activation signaling pathway. This regulatory capacity of autophagy can potentially prevent or delay the progression of HCC. Nowadays, many studies have shown that different types of herbal monomers such as the more common quercetin, baicalein, berberine and emodin can further regulate autophagy and exert preventive and therapeutic effects on HCC through the modulation of mTOR and other related signaling pathways and so on. In this paper, we examine the mechanisms of autophagy, key proteins and signaling pathways involved, and the modulation of autophagy by Chinese medicine monomers in the prevention and treatment of HCC. This review aims to provide valuable insights for the development of Chinese medicine strategies against HCC and to inform the rational use of these therapies in clinical practice.",
"40744389": "ID: 40744389\nTitle: Natural bioactive compounds as modulators of autophagy: A herbal approach to the management of neurodegenerative diseases.\nAbstract: Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Polyglutamine (polyQ), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS) disease are a significant health concern that affects millions of people every year worldwide. The main pathological hallmark of various NDs is the formation of misfolded protein aggregation and accumulation of inclusion bodies. These protein aggregates are mainly responsible for producing toxic effects and initiating neuronal cell death, ultimately promoting various NDs. On the other hand, the patients suffering from these kinds of diseases live in impaired conditions, imposing a substantial financial burden on the family. However, the current treatment strategies can only offer temporary relief from the disease symptoms and can't reverse the disease completely. Hence, there is an urgent need for specific and novel drug treatment that can significantly eradicate NDs. Ubiquitin proteasome system (UPS) and autophagy are the two essential intracellular defensive mechanisms that are involved in clearing the protein aggregates, pathogens, and damaged organelles from the cytoplasm and maintaining protein homeostasis. Nevertheless, UPS is inefficient in removing some kinds of organelles and aggregating-prone proteins, specifically in neuronal and glial cells. Under this kind of circumstance, the autophagy mechanism plays a vital role in eliminating the accumulated protein aggregates and other toxic elements from the cytoplasm of the neuronal cells that initiate oxidative stress. However, in NDs, the autophagy function is impaired, and the protein aggregates can't be eliminated effectively. Hence, forced up-regulation of autophagy function by applying various external agents could be a potential therapeutic strategy to control NDs like AD, PD, HD, and ALS. In this review, we focused on different kinds of plant-derived compounds that induce autophagy. We also discussed the role of these plant-derived autophagy modulators in various NDs. In this way, the current review will be a standalone reference to the researchers working in this area.",

RETREG1/FAM134B is an ERphagy receptor that acts by inducing ER membrane curvature and scission through oligomerization. Interestingly, RETREG1\u00a0has also been implicated in the cellular response against pathogen infection. Multiple microbes have developed strategies to inhibit ERphagy by targeting RETREG1. In a recent study, we characterized an unidentified mechanism of bacterial-mediated inhibition of ERphagy. Specifically, we found that Salmonella enterica Serovar Typhimurium, a well-known intracellular pathogen that continues to be a major cause of foodborne infections worldwide, inhibits ERphagy by specifically targeting the activity of RETREG1, leading to a pronounced increase in Salmonella burden. We show that Salmonella prevents RETREG1 oligomerization, which is required for efficient ERphagy. Conversely, Salmonella-mediated ERphagy blockage can be bypassed by promoting RETREG1 oligomerization, which recovers ERphagy levels. Salmonella infection also decreases RETREG1 phosphorylation and acetylation, previously reported to be requisite steps in RETREG1-driven ERphagy. Furthermore, in vivo analysis of retreg1 knockout mice infected with Salmonella reveals increased intestinal damage and bacterial levels. Our results provide insights into the interplay between ERphagy and bacterial infection, highlighting a key role for RETREG1 in innate immunity.",

This study investigates the therapeutic potential of flavonols-quercetin, kaempferol, myricetin, and fisetin-in targeting A\u03b2 aggregation and mitigating AD pathology through diverse molecular mechanisms. Our findings reveal that flavonols effectively inhibit A\u03b2 oligomerization and fibril formation, reduce oxidative stress via Nrf2/HO-1 pathway activation, and suppress neuroinflammation by modulating microglial polarization. Additionally, these compounds enhance mitochondrial function, promote autophagy-mediated clearance of A\u03b2 aggregates, and regulate key enzymes such as \u03b2-secretase (BACE1) and \u03b1-secretases (ADAM10/17), favoring non-amyloidogenic pathways. Quercetin demonstrated neuroprotective effects by activating TrkB signaling, reducing tau phosphorylation, and enhancing synaptic plasticity. Kaempferol prevented A\u03b2-induced apoptosis via the ER/ERK/MAPK pathway and inhibited acetylcholinesterase activity, improving cognitive outcomes. Myricetin ameliorated mitochondrial dysfunction and oxidative damage through GSK3\u03b2/ERK2 signaling modulation and showed enhanced brain bioavailability when delivered via nanostructured lipid carriers. Fisetin reduced A\u03b2 burden by upregulating neprilysin expression, suppressed neuroinflammation, and improved synaptic function by restoring synaptic protein levels. Overall, flavonols exhibit multi-targeted therapeutic potential against AD by addressing its complex pathogenesis. Their ability to cross the blood-brain barrier and low toxicity profiles position them as promising candidates for further clinical development. This study underscores the potential of flavonols as natural agents for AD treatment and highlights their role in advancing multi-mechanistic therapeutic strategies.",

Heat shock proteins, which serve as critical chaperone molecules in response to stress-related damage, are essential for maintaining protein homeostasis within cells. In this family of proteins, Heat Shock Protein 72 (Hsp72) stands out for its acute responsiveness to thermal stress. It can swiftly be produced in reaction to the surge of misfolded proteins caused by heat, thus maintaining the equilibrium of intracellular protein metabolism. This analysis explores the function of Hsp72 in maintaining protein homeostasis, focusing on its ability to assist in the refolding of incorrectly folded proteins and to guide their breakdown through the ubiquitin-proteasome and autophagy systems. Furthermore, the potential mechanisms through which cells may eliminate misfolded protein aggregates via the secretory autophagy pathway under heat stress conditions are explored. This study systematically analyzes the various mechanisms by which Hsp72 influences misfolded protein metabolism and discusses the relevance of each pathway in the context of heat stress. Integrating findings from prior laboratory research, it is concluded that Hsp72 plays a pivotal role in regulating misfolded protein metabolism through the secretory autophagy pathway, thereby sustaining intracellular protein homeostasis during heat stress. This investigation expands the functional network of Hsp72 in maintaining protein homeostasis and elucidates the molecular pathways involved in its regulation of misfolded protein metabolism under heat stress, providing a framework for future research on Hsp72's role in cellular recovery from heat stress.",

Despite the worldwide increase in disease incidence, effective therapies remain unavailable. A common pathological hallmark of neurodegenerative diseases is the accumulation of misfolded protein aggregates. Accordingly, numerous studies and therapeutic strategies have focused on targeting these toxic aggregates and protein quality control via autophagy, a vital cellular recycling mechanism. Autophagy dysregulation has been implicated in the pathogenesis of several neurodegenerative diseases. Induced pluripotent stem cell (iPSC) technology has emerged as a powerful platform for modeling neurodegenerative diseases, and iPSC-based models provide human-relevant systems for studying autophagic dysfunction in vitro. In this review, we discuss the key findings of recent studies investigating autophagy in iPSC-based models of neurodegenerative diseases, including Alzheimer's disease, amyotrophic lateral sclerosis, frontotemporal dementia, and other diseases.",
"41351658": "ID: 41351658\nTitle: Senolytics as Modulators of Critical Signaling Pathways: a Promising Strategy to Combat Brain Aging and Neurodegenerative Disorders.\nAbstract: Aging of the brain, an intricate process, is a significant risk factor for neurodegenerative disorders (NDDs), such as Alzheimer's disease and Parkinson's disease. Senescent cell accumulation is an important hallmark of brain aging. These cells resist apoptotic cell death, produce proinflammatory cytokines, increase oxidative stress, and store toxic proteins that exacerbate neurodegeneration. These senescent cells cause neuroinflammation and dysfunction of the neuronal microenvironment by transmitting senescent phenotypes to neighboring healthy cells. Senolytics have become a viable treatment option to reduce the effects of brain aging since they specifically target and destroy senescent cells. Numerous senolytic compounds, such as dasatinib, fisetin, and quercetin, effectively eliminate senescent cells and reduce the accumulation of harmful substances, including misfolded toxic protein aggregates and reactive oxygen species, thereby helping to maintain tissue homeostasis. These medications aid in reducing oxidative stress and inflammation, two significant factors in brain aging and NDDs, by encouraging the removal of senescent cells. The key molecules involved in this process are mTOR, Nrf2-Keap1, AMPK, and Sirtuin 1 (SIRT1). The modulation of the mTOR and AMPK pathways affects autophagy and cellular metabolism, facilitating the elimination of harmful accumulations and damaged cell organelles. In addition, cellular repair and improved antioxidant defense are encouraged by the activation of the SIRT1 and Nrf2 pathways. The combination of senolytic therapy with these signaling pathways provides a novel approach to attack the cellular and molecular foundations of brain aging and neurodegenerative disorders.",
"41450115": "ID: 41450115\nTitle: Proteotoxic stress triggers TFEB- and TFE3-mediated autophagy and lysosomal biogenesis via non-canonical MTORC1 inactivation.\nAbstract: Proteotoxic stress, arising from conditions that cause misfolded protein accumulation, is closely linked to the pathogenesis of multiple diseases. Macroautophagy/autophagy activation is considered a compensatory mechanism to maintain protein homeostasis, but the underlying regulatory mechanisms remain incompletely understood. Here, we show that proteotoxic stress induced by proteasome inhibition, puromycin treatment, or polyglutamine-expanded HTT (huntingtin) expression promotes nuclear accumulation of TFEB and TFE3, key regulators of lysosomal biogenesis and autophagy. Mechanistically, TFEB activation under proteotoxic stress occurs independently of canonical MTORC1 inactivation mediated by TSC2 or ATF4. Instead, it involves non-canonical inhibition of MTORC1 via RRAG GTPases. Proteotoxic stress disrupts the RRAGC-TFEB interaction, preventing TFEB recruitment to lysosomes and subsequent MTORC1 phosphorylation. An activated RRAGC mutant rescues impaired lysosomal localization and nuclear accumulation of TFEB, while co-overexpression of FLCN and FNIP2, a GAP for RRAGC, partially restores stress-induced TFEB dephosphorylation. In addition, proteasome inhibition activates non-canonical autophagy. Deletion of ATG16L1 or ATG5, which known blocks Atg8-family protein lipidation and sequesters the FLCN-FNIP2 complex, partially abolishes proteotoxic stress-induced TFEB dephosphorylation and nuclear accumulation. Together, these findings demonstrate that proteotoxic stress triggers both non-canonical autophagy and TFEB-mediated canonical autophagy, with Atg8-family protein lipidation contributing to TFEB activation. Our results provide novel insights into how proteotoxic stress engages non-canonical MTORC1 inhibition and TFEB activation, thereby enhancing understanding of cellular adaptation to proteotoxic stress.Abbreviations: ALP, autophagy-lysosomal pathway; ATF4, activating transcription factor 4; Baf A1, bafilomycin A1; CHX, cycloheximide; BTZ, bortezomib; CFZ, carfilzomib; CQ, chloroquine; CTSB, cathepsin B; CTSD, cathepsin D; DQ-BSA, dequenched-bovine serum albumin; EIF4EBP1/4EBP1, eukaryotic translation initiation factor 4E binding protein 1; ER, endoplasmic reticulum; MAP1LC3B/LC3B, microtubule associated protein 1 light chain 3 beta; MG132, carbobenzoxy-Leu-Leu-leucinal; MTORC1, mechanistic target of rapamycin kinase complex 1; RPS6KB1/p70, ribosomal protein S6 kinase B1; RRAG, Ras related GTP binding; SQSTM1/p62, sequestosome 1; TFE3, transcription factor E3; TFEB, transcription factor EB; TSC2, TSC complex subunit 2; tfLC3, tandem fluorescent LC3; UPS, ubiquitin-proteasome system.",

FM has the effect of calming Liver to stop endogenous Wind, and has been used for thousands of years in the treatment of Parkinson's disease (PD), as recorded in ancient formulas such as Wumei Pills. However, the specific mechanism by which it treats PD remains larger unclear. The aim of this study was to investigate the effects and mechanisms by which the active ingredients of FM (Fructus Mume flavonoids, FMF) mitigate the progression of PD. We isolated FMF from FM and explored its chemical composition and active compound content. In vivo and in vitro PD models were employed to investigate the alleviative effects of FMF on PD and its underlying mechanisms. We identified 193 compounds and quantified 154 flavonoid compounds in the FMF. Six compounds were present at concentrations exceeding 100\u00a0\u03bcg/g, namely Isorhamnetin (1287.0639\u00a0\u03bcg/g), Narcissin (764.9639\u00a0\u03bcg/g), Nicotiflorin (613.8568\u00a0\u03bcg/g), Quercetin (435.5215\u00a0\u03bcg/g), Nepitrin (295.4833\u00a0\u03bcg/g), and Kaempferol (241.9767\u00a0\u03bcg/g). Moreover, FMF alleviated behavioral deficits in PD rats. FMF also inhibited the loss of neurons and the formation of \u03b1-synuclein aggregates, and promoted the expression of tyrosine hydroxylase in the substantia nigra pars compacta in PD rats. In vivo and in vitro PD models demonstrated that autophagy inhibition significantly abolished the neuroprotective effects of FMF. Mechanically, FMF could enhance mitophagy to attenuate the mitochondrial dysfunction by activating the Ca2+/calmodulin-dependent protein kinase kinase \u03b2 (CaMKK\u03b2)/AMP-activated protein kinase (AMPK) signaling pathway. FMF promotes neuronal mitophagy to exert the neuroprotective effects by activating the CaMKK\u03b2/AMPK signaling pathway. These findings provide a theoretical foundation for the application of FM in the treatment of PD and promote the clinical application of FM.",

Recent studies have highlighted the crucial role of autophagy in mediating mycotoxin-induced toxicity. As a highly conserved intracellular degradation pathway, autophagy maintains cellular homeostasis by selectively removing damaged organelles and misfolded protein aggregates. However, its function in the context of mycotoxin exposure is dualistic: it can act either as a protective mechanism or contribute to detrimental cellular outcomes.

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

Blood-brain barrier (BBB)-penetrable, dual-target nanomedicines for microglial inflammation and neuronal degeneration remain challenging. In this study, we fabricated a brain-targeted, pH- and reactive oxygen species (ROS)-responsive nanogel (NG) platform using dextran (Dex) as the main polysaccharide backbone, crosslinked with inflammation-targeting fibronectin (FN), and loaded with neuroprotective quercetin (Que). Dex-FN/Que NGs exhibited a uniform spherical morphology with an average diameter of 187\u00a0nm, favorable colloidal stability, and stimuli-triggered drug release behavior. Abundant hydroxyl groups on Dex enabled efficient BBB penetration, while FN mediated integrin-dependent internalization in microglia and neurons. These NGs suppressed the nuclear factor-kappa B (NF-\u03baB) signaling pathway, scavenged ROS, promoted favorable microglial polarization, and balanced oxidative stress. Meanwhile, mitophagy flux activated by the NGs in neurons exerted strong neuroprotection effect. In a mouse model of PD, Dex-FN/Que NGs effectively crossed the BBB and accumulated in injured brain regions, significantly protecting dopaminergic neurons, improving motor function, and relieving depressive-like behaviors. Therapeutic benefits arose from normalized microglial polarization, reduced oxidative stress, and inhibited neuronal ferroptosis. This Dex-based stimuli-responsive nanoplatform provides a promising brain-targeted strategy for the treatment of PD and other neurological disorders.",

Although excessive stress is known to inactivate these mechanisms and thereby induce mitophagy in cancer cells, the detailed molecular mechanisms coordinating these mitochondrial quality control processes remain unclear. Herein, we identify CLPX, a mitochondrial protease subunit, as an iron-sulfur protein, which requires a [4Fe-4S] cluster to bind with CLPP to exert proteolysis function. Iron chelation impairs the assembly of the [4Fe-4S] cluster onto CLPX, thereby disrupting mitochondrial proteostasis maintenance and inducing mitophagy. Furthermore, cysteine deprivation caused by excessive reactive oxygen species accumulation hinders iron-sulfur cluster biosynthesis, thereby undermining CLPX function and inducing mitophagy. Our research elucidates an iron-sulfur cluster-dependent mechanism sustaining mitochondrial proteostasis.",

A fatigue model was established using C2C12 mouse myoblasts induced by using a combined treatment of H2O2 induction and electrical stimulation. The ethyl acetate, butan-1-ol, and water extracts enhanced cell viability and mitochondrial membrane potential while reducing lactate dehydrogenase and reactive oxygen species levels. RT-qPCR indicated these extracts promote mitochondrial biogenesis, with ethyl acetate extract showing the most significant effect. Compositional analysis via liquid chromatography-mass spectrometry revealed that the ethyl acetate extract primarily contained phenolic acids such as caffeic acid, while the butan-1-ol fraction was rich in flavonoids including rutin and quercetin. Although the water extract shared a similar compositional profile, its antioxidant activity was lower due to insufficient levels of characteristic active substances. The butan-1-ol extract exhibited the highest chemical richness, with 2972 compounds tentatively identified.",

Here, we evaluated the synergistic antibiofilm activity of quercetin and carvacrol against a catheter-derived C. albicans isolate (CRL7) and delineated the underlying cellular and structure-based mechanisms. Combination therapy markedly enhanced antifungal potency, reducing MICs from 200 \u03bcg/mL (carvacrol) and 240 \u03bcg/mL (quercetin) to 17 \u03bcg/mL and 10.9 \u03bcg/mL, respectively (FICI = 0.13), indicating strong synergy. The quercetin-carvacrol combination reduced biofilm biomass by \u223c82% at \u00bd MIC (vs. 51-69% for monotherapy) and decreased metabolic activity by \u223c68% at \u00bd MIC (vs. 40-42%). Mechanistically, the combination caused profound membrane destabilization, evidenced by increased nucleic acid/protein leakage and a pronounced reduction in DPH membrane fluorescence, accompanied by extensive disruption of biofilm architecture on SEM. The combination also triggered oxidative stress, increasing intracellular ROS by 3.5-fold and inducing apoptosis-like cell death with robust metacaspase activation (mean fluorescence intensity: 160 \u00b1 3.5 MFI) compared with quercetin (110 \u00b1 2.3 MFI) or carvacrol (120 \u00b1 2.1 MFI) alone, supported by nuclear condensation signatures. Consistently, qPCR analysis demonstrated downregulation of key biofilm and virulence determinants, including adhesion and hyphal-associated genes (ALS1/HWP1/ECE1/LIP3) and oxidative-stress regulators (CAP1/SOD1), indicating suppression of biofilm-associated transcriptional programs. To complement experimental findings, structure-based computational analysis (molecular docking and normal mode analysis) predicted stable binding of quercetin and carvacrol to virulence-linked targets (ALS3, HWP1, CAP1, SOD1), with quercetin showing denser hydrogen-bond/\u03c0-interaction networks and higher complex rigidity signatures relative to carvacrol. Collectively, these results support a dual mechanism in which quercetin and carvacrol synergistically dismantle catheter-derived C. albicans biofilms through membrane disruption, ROS-mediated apoptosis-like cell death, virulence gene suppression, and structure-based interference with adhesion and redox-defense pathways, supporting the quercetin-carvacrol combination as a candidate warranting further preclinical evaluation.

However, scientific evidence supporting its traditional use in pain management remains limited. The present study aimed to evaluate the antinociceptive activity, safety profile, phytochemical composition, and possible mechanisms underlying the antinociceptive effects of the ethanolic extract of flowers of C. gigantea (CGEE). Phytochemical profiling was performed using qualitative screening, total phenolic and flavonoid assays, DPPH radical scavenging assay, and HPLC analysis. Acute and subacute oral toxicity studies were conducted according to OECD guidelines 423 and 407, respectively. Antinociceptive activity was evaluated using hot plate, tail flick, formalin-induced paw licking, and acetic acid-induced writhing models in rats. Mechanistic investigations were carried out using Nalbin, Atropine, Glibenclamide, and Terazosin to assess the involvement of opioidergic, cholinergic, KATP channel, and noradrenergic pathways respectively. Phytochemical screening revealed the presence of phenolics, flavonoids, alkaloids, glycosides, tannins, saponins, amino acids, and reducing sugars. HPLC analysis identified chlorogenic acid, quercetin, gallic acid, syringic acid, vanillic acid, and coumaric acid derivatives.

Here, we systematically evaluated the long-term effects of D\u2009+\u2009Q in naturally aged mice using multi-omics approaches. We show that D\u2009+\u2009Q treatment reduces senescence markers (p16, p21, SA-\u03b2-gal), restores the anti-aging protein Klotho, and attenuates renal fibrosis and inflammation. Proteomic profiling reveals that D\u2009+\u2009Q enhances apoptotic clearance of senescent cells and promotes proliferative and regenerative pathways. Moreover, D\u2009+\u2009Q reactivates PPAR\u03b1 signaling, improves fatty acid oxidation, and reduces lipid accumulation in aged kidneys. Single-cell transcriptomics further demonstrates that D\u2009+\u2009Q reverses transcriptional aging signatures across multiple renal cell types and remodels cell-type-specific pathways associated with metabolism, inflammation, and fibrosis. Cell-cell communication analysis reveals that D\u2009+\u2009Q normalizes the hyperconnected intercellular network in aged kidneys, particularly by modulating inflammation-related signaling.

Therefore, an ovalbumin (OVA)-induced AR mouse model was established to investigate whether quercetin can treat AR by regulating the TLR4/MyD88/IRAK4 signaling pathway. OVA and aluminum hydroxide were injected intraperitoneally for sensitization, and OVA was dripped into the nose to establish a mouse model of AR. The mice were scored on behaviors such as scratching, sneezing and a runny nose to assess the success of the modeling. The treatment groups were given the relevant drugs (dexamethasone and quercetin) by gavage for 1 week after successful modeling. Following the completion of treatment, the serum OVA-IgE, IL-4, IL-13, IL-1\u03b2, IL-17 and IL-10 levels were measured; changes in the nasal mucosa were observed; protein and mRNA expression levels of TLR4, MyD88, IRAK4 and NF-\u03baB in lung tissue were determined; and changes in the percentages of regulatory T cells (Tregs) and T helper 17 (Th17) cells in the spleen were assessed. The results showed that compared with the normal control (NC) group, the allergic symptom scores were >10 points, and the serum levels of OVA-IgE, IL-4, IL-13, IL-1\u03b2 and IL-17 increased, whereas the serum level of IL-10 decreased in the OVA group. Detachment and necrosis of the nasal mucosa, accompanied by tissue edema and inflammatory cell infiltration, were observed in the OVA group. Compared with the NC group, the relative expression mRNA and protein levels of TLR4, MyD88, IRAK4 and NF-\u03baB in lung tissues increased, the percentage of Tregs decreased and the percentage of Th17 cells increased in splenocytes of the OVA group. Based on these results, it was hypothesized that quercetin inhibits inflammatory responses and induces immune tolerance by regulating the TLR4/MyD88/IRAK4 signaling pathway in a mouse model of AR.",

Consequently, single-target treatment frequently has low long-term efficacy. Brassica rapa L. (BRL) turnip, a medicinal and dietary crucifer rich in glucosinolates, flavonoids, and phenolic acids, offers significant potential for blood pressure modulation. Using a comprehensive in silico approach that combines network pharmacology, molecular docking, molecular dynamics simulation, and ADMET-guided screening, this study examines the multitarget antihypertensive potential of BRL. In the list of 189 phytoconstituents identified from extensive databases, 9 drug-like candidates were ultimately selected using SwissADME profiling and Lipinski's rule of 5. Predicted protein targets identified through SwissTargetPrediction and the similarity ensemble approach were cross-referenced with hypertension-associated genes from GeneCards and online Mendelian Inheritance in Man, yielding 246 common targets. Protein-protein interaction analysis identified an essential component comprising 10 hub genes, including EGFR, PIK3CA, FYN, PTK2, SRC, PTPN11, PIK3R1, CTNNB1, and AKT1, indicating a critical role for kinase-driven vascular signalling. The functional enrichment analysis identified redox homeostasis, vascular regulatory balance, and the PI3K-AKT and nitric/eNOS signalling pathways. AutoDock Vina docking identified quercetin (-\u200911.4\u00a0kcal/mol), kaempferol and isorhamnetin (-\u200911.2\u00a0kcal/mol), gluconasturtiin (-\u200911.2\u00a0kcal/mol) as top ligands. Schrodinger molecular dynamics simulations over 100\u00a0ns confirmed the stability and energetically favorable nature of the protein-ligand interactions. Overall, BRL demonstrates strong multitarget antihypertensive potential, with prioritized lead molecules for further validation.

However, the key regulatory genes and immune microenvironment characteristics require further exploration. This study integrated the bulk transcriptome and single-cell RNA sequencing data, and utilized bioinformatics methods to screen the differentially expressed genes (DEGs) of AS. The weighted gene co-expression network analysis (WGCNA) was used to identify the key gene modules related to lipid metabolism and autophagy. The core regulatory genes were further screened based on the machine learning algorithm (LASSO regression). The enrichment scores of 28 immune cell subtypes were calculated by ssGSEA, and the correlation between the immune infiltration characteristics and the expression levels of the three core genes (PRKCB, NLRC4, and TNFSF10) was analyzed by Spearman correlation analysis. The single-cell transcriptome data analysis was performed to determine the cell subtype distribution characteristics of the core genes and to compare the expression differences in lipid metabolism-autophagy-related gene expression across distinct cell subtypes. In addition, we screened potential drugs targeting the key genes from the public drug database, and simulated the binding mode of approved drugs with the active site of PRKCB by molecular docking technology. Ultimately, the expression of target factors in mouse aortic tissues was determined by quantitative real-time PCR (RT-qPCR), Western blotting, and immunohistochemical (IHC) analysis. Concurrently, the levels of TNFSF10 in mouse plasma were confirmed through enzyme-linked immunosorbent assay (ELISA). Three lipid metabolism-autophagy core regulatory genes, PRKCB, NLRC4, and TNFSF10, were identified. These genes were significantly associated with the immune microenvironment of AS plaques and exhibited different cell subpopulation distribution patterns. The macrophage subpopulations showed higher lipid metabolism-autophagy regulatory activity. Molecular docking revealed that the anti-atherosclerotic drugs quercetin and atenolol can stably bind to the active site of PRKCB (with docking energies of -8.3\u2009kcal/mol and -6.2\u2009kcal/mol, respectively), a finding that identifies PRKCB as a candidate target worthy of further attention. Experimental evidence confirmed that the expression of these three key factors was significantly elevated in atherosclerotic plaque tissue, and the levels of TNFSF10 in the plasma of atherosclerotic mice were also significantly higher than those in the control group. This study identifies PRKCB, NLRC4, and TNFSF10 as key hub genes that link lipid metabolism and autophagy in AS, and highlights their potential as diagnostic biomarkers and therapeutic targets.",

The present study was designed to assess the morphological diversity, seed protein profiles, and phytochemical composition of fifteen landraces of R. fruticosus collected from different ecological zones of the Malakand Division, Khyber Pakhtunkhwa, Pakistan. Morphological characteristics were evaluated using the International Board for Plant Genetic Resources (IBPGR) descriptors, incorporating both qualitative and quantitative traits in a randomized complete block design. Seed protein diversity was assessed through sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), while phytochemical composition was quantified using high-performance liquid chromatography with ultraviolet detection (HPLC-UV). Morphological traits exhibited significant variability, with a mean coefficient of variation (CV) of 36.72%. The most variable traits were single fruit weight (CV\u2009=\u200973.16%), five-fruit weight (CV\u2009=\u200964.38%), number of branches per plant (CV\u2009=\u200933.33%), plant height (CV\u2009=\u200931.31%), and stalk length (CV\u2009=\u200930.11%). Principal component analysis (PCA) explained 89.71% of the total variation, with plant height, leaflet number, and fruit weight contributing predominantly to landrace differentiation. SDS-PAGE analysis of seed proteins revealed 21 polymorphic bands (molecular weight range: 14.4-97.4 kDa), with high diversity indices recorded for markers B-03, B-06, B-08, B-12, and B-21 (Shannon diversity index H'\u2009=\u20091.10-1.39; CV\u2009=\u200935.36-93.54%). HPLC-UV analysis identified twelve phenolic compounds in selected genotypes, including quercetin (5.12-8.74 \u00b5g/mL), morin (3.45-6.89 \u00b5g/mL), and epigallocatechin gallate (2.88-7.23 \u00b5g/mL).

"42392409": "ID: 42392409\nTitle: Macrophage Senescence and Programmed Cell Death in Atherosclerosis: Mechanisms, Cross-Talk, and Emerging Therapeutic Strategies.\nAbstract: Atherosclerosis imposes a heavy burden on global healthcare systems and remains the leading cause of mortality worldwide, with macrophage dysfunction playing a critical role in its pathogenesis. This review examines the dual roles of macrophage senescence and programmed cell death (PCD) in the progression of atherosclerosis, highlighting their mechanisms, cross-talk and emerging therapeutic strategies. Macrophage senescence-characterized by irreversible cell cycle arrest, mitochondrial dysfunction, and the senescence-associated secretory phenotype (SASP)-exacerbates chronic inflammation and impairs tissue repair. Meanwhile, PCD pathways, including apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagy, regulate inflammatory responses and cellular homeostasis; however, their dysregulation accelerates arterial pathology. Shared molecular pathways such as NF-\u03baB, mTOR, and p53 govern both processes, while distinct features define their respective contributions: senescence reflects cumulative damage and functional decline, whereas PCD involves regulated, context-dependent cellular demise. In atherosclerosis, senescent macrophages promote plaque instability through SASP-driven inflammation and impaired efferocytosis, while PCD modalities such as necroptosis and pyroptosis exacerbate necrotic core formation. Emerging therapeutic strategies targeting these pathways-including senolytics, NLRP3 inhibitors, ferroptosis suppressors, and autophagy enhancers-show promise in preclinical models by mitigating inflammation, restoring macrophage function, and stabilizing plaques. Pharmacological interventions such as quercetin (a p38 MAPK inhibitor), melatonin (an Nrf2 activator), and senolytic agents illustrate the potential to disrupt the senescence-PCD axis. This synthesis underscores the importance of delineating context-specific roles of macrophage senescence and PCD in atherosclerosis, offering a roadmap for dual-targeted therapies to alleviate cardiovascular burden. By integrating mechanistic insights with translational applications, this review identifies novel biomarkers and therapeutic avenues to combat aging-related atherosclerotic pathologies.",
"42392709": "ID: 42392709\nTitle: [Effects of different fermentation conditions on microbial community and chemical composition of Huafengdan Yaomu].\nAbstract: To investigate the effects of different fermentation conditions on the microbial community structure and chemical composition of Huafengdan Yaomu, this study compared the physicochemical properties, microbial composition, and chemical composition under fermentation with controlled temperature and humidity with those under natural fermentation. The results show the darkening of Yaomu color, significant pH changes, and decreases in the contents of total alkaloids and total flavonoids after fermentation(P<0.05). Microbial community analysis reveals that the number of bacterial amplicon sequence variants(ASVs), abundance, and diversity are significantly increased under fermentation with controlled temperature and humidity, with dominant genera including Ligilactobacillus, Levilactobacillus, and Pichia. In contrast, the natural fermentation group is dominated by Levilactobacillus, Lactiplantibacillus, and Pichia. 584 differential components are screened from 3 003 compounds by metabolomic analysis, including 40 alkaloids and 31 flavonoids. The fermentation group with controlled temperature and humidity exhibits the highest number of differential compositions, with the number of 25 alkaloids including hydropeimine and deltaline significantly increasing, 15 alkaloids including neoline significantly decreasing, 18 flavonoids including loquatoside increasing, and 13 flavonoids including kaempferol decreasing. Natural fermentation is conducive to the production of flavonoid compositions such as kaempferol and quercetin, whereas its effect on reducing toxic alkaloids is less pronounced compared to the fermentation with controlled temperature and humidity. Correlation analysis further indicates that alkaloid compositions are positively correlated with bacterial genera such as Lactiplantibacillus, while flavonoid compositions are positively correlated with fungal genera such as Wickerhamomyces. In conclusion, fermentation conditions significantly affect the chemical composition of Yaomu by regulating the microbial community structure. Fermentation with controlled temperature and humidity demonstrates greater advantages in reducing toxic components, providing a scientific basis for optimizing traditional fermentation processes and improving the quality control of TCM.",

Network pharmacology was used to construct a "drug-core component-key target-pathways-disease" network to identify potential targets and related pathways associated with drug efficacy. Thirty 3-month-old male APP/PS1 transgenic mice were randomly divided into a model group, a quercetin group(100 mg\u00b7kg~(-1)), and a donepezil hydrochloride group(0.5 mg\u00b7kg~(-1)), while age-matched C57BL/6J mice from the same litter served as the control group. Each group consisted of 10 mice, and the treatment groups received the corresponding drug interventions for 24 weeks. The Morris water maze(MWM) test was used to assess memory performance, and the nest-building test was applied to evaluate daily living ability. hematoxylin-eosin(HE) staining, Nissl staining, and immunohistochemistry were used to assess pathological changes in hippocampal neurons. Western blot analysis was used to detect the expression levels of tau, phosphorylated(p)-tau, interleukin-1\u03b2(IL-1\u03b2), tumor necrosis factor-\u03b1(TNF-\u03b1), brain-derived neurotrophic factor(BDNF), cyclic adenosine monophosphate(cAMP), protein kinase A(PKA), p-PKA, cAMP response element-binding protein(CREB), and p-CREB-related signaling proteins in hippocampal tissue. Network pharmacology analysis identified 165 quercetin-related active component targets and 4 324 learning-and memory-related targets. Intersection analysis yielded 71 AD-related core genes. Protein-protein interaction(PPI) network analysis identified protein kinase B(Akt1), estrogen receptor 1(ESR1), epidermal growth factor receptor(EGFR), and non-receptor tyrosine kinase(SRC) as core target genes. Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis indicated that quercetin may regulate AD progression through the PI3K/Akt signaling pathway, cAMP signaling pathway, TNF signaling pathway, and EGFR tyrosine kinase inhibitor resistance-related pathways. Animal experiments showed that, compared with the control group, the model group exhibited significantly reduced nesting scores, prolonged escape latency(P<0.05), and fewer platform crossings(P<0.05). The number of neurons in the cortex and hippocampus was significantly decreased, and extracellular amyloid \u03b2(A\u03b2) deposition was significantly increased(P<0.01). In addition, the expression levels of p-tau/tau, IL-1\u03b2, TNF-\u03b1, cAMP, p-PKA/PKA, and p-CREB/CREB in hippocampal tissue were significantly elevated(P<0.01), whereas BDNF protein expression was significantly reduced(P<0.01). Compared with the model group, the quercetin and donepezil hydrochloride groups showed significantly increased nesting scores, shortened escape latency(P<0.05), and increased numbers of platform crossings(P<0.05). The number of neurons in the hippocampal CA1 region was significantly increased(P<0.01), and the expression levels of p-tau/tau, IL-1\u03b2, TNF-\u03b1, cAMP, p-PKA/PKA, and p-CREB/CREB in hippocampal tissue were significantly decreased(P<0.05, P<0.01). These results indicate that quercetin can significantly improve cognitive impairment in APP/PS1 transgenic mice, and its mechanism may be associated with activation of the cAMP/PKA/CREB signaling pathway and reversal of the upregulation of pro-inflammatory cytokines, including TNF-\u03b1 and IL-1\u03b2.",
"42392795": "ID: 42392795\nTitle: [Research progress on intervention of active components of Bupleuri Radix in metabolic dysfunction-associated fatty liver disease based on multiple parallel strike theory].\nAbstract: Metabolic dysfunction-associated fatty liver disease(MAFLD) is a prevalent chronic liver disease worldwide. Due to its complex pathogenesis, there is currently no specific drug capable of intervening throughout the entire pathological process, nor a unified and definitive treatment protocol in clinical practice. In traditional Chinese medicine, MAFLD falls under the category of diseases such as "hypochondriac pain" and "liver disease", with the core pathogenesis being "stagnation of the liver meridian and obstruction of Qi movement". The pharmacological characteristics of Bupleuri Radix(BR), which "soothes the liver, relieves stagnation, and promotes Qi movement", are highly consistent with this pathogenesis. Furthermore, data mining studies have shown that BR is among the most frequently used herbs in TCM clinical protocols for treating MAFLD, and its herb pairs and classic formulas have demonstrated favorable therapeutic effects in clinical application. Modern pharmacological studies have also confirmed that BR is rich in active ingredients, including saponins(e.g., saikosaponin A/D/B2), volatile oils(e.g., D-limonene, hexanoic acid), flavonoids(e.g., quercetin, rutin, kaempferol), and polysaccharides. These active ingredients can target multiple pathological aspects of the "multiple parallel hits" in MAFLD, such as improving insulin resistance(IR), alleviating endoplasmic reticulum stress(ERS), repairing mitochondrial function, regulating oxidative stress(OS) response, modulating intestinal microbiota imbalance, and inhibiting inflammasome activation, thereby slowing the progress of MAFLD. Its mechanism of action is closely related to the regulation of PI3K/Akt, PPAR, Nrf2, AMPK, MAPK, PINK1/Parkin, NLRP3 inflammasome and the "gut-liver axis", reflecting the integrative regulatory advantages of TCM's multi-component, multi-target and multi-mechanism approach. Future in-depth studies should focus on precise component profiling of BR, validation of key targets, and the synergistic mechanisms within "formula-component" interactions to better leverage the value of BR in the prevention and treatment of MAFLD.",
"42394568": "ID: 42394568\nTitle: A simple, sensitive microsample LC-MS assay for quercetin and isorhamnetin in mouse and human plasma: application to EMIQ treatment in myotonic dystrophy type 1.\nAbstract: Quercetin, a dietary flavonoid with emerging therapeutic relevance in myotonic dystrophy type 1 (DM1), has low solubility and poor oral bioavailability. Enzymatically modified isoquercitrin (EMIQ), a water-soluble prodrug, raises systemic quercetin exposure. Pharmacokinetic studies require a sensitive assay that uses minimal sample volume. We developed a single-quadrupole liquid chromatography-mass spectrometry (LC-MS) assay for free quercetin, total quercetin (after enzymatic hydrolysis of glucuronide and sulfate conjugates), and the methylated metabolite isorhamnetin in mouse and human plasma. The method used protein precipitation, 10\u2009\u00b5L of plasma, reversed-phase C18 separation, and single-ion recording of [M+H]+ adducts. Validation followed a fit-for-purpose approach consistent with M10 guidelines, and the assay was applied to plasma from EMIQ-treated DM1 and wild-type mice (15\u2009g/L for 6 and 12\u2009weeks). Calibration curves showed r2\u2009 > 0.99, with an LLOQ of 0.070\u2009\u00b5M for quercetin in both matrices. The assay was successfully validated for quercetin in mouse and human plasma. Total quercetin and isorhamnetin were quantifiable in all treated mice. Exploratory analysis suggested glucuronidation as the major conjugation pathway. This simple, cost-effective microsampling assay suits preclinical and translational studies of EMIQ in DM1, though the conjugation findings remain exploratory. Quercetin is a natural compound found in many foods that researchers are studying as a possible treatment for myotonic dystrophy type 1 (DM1), an inherited muscle disease. A problem is that the body absorbs quercetin poorly, so a more soluble form called EMIQ is used to raise its levels in the blood. To study how much quercetin reaches the blood, scientists need a reliable way to measure it, but the levels are often very low and usually require costly equipment and large blood samples. We developed a simpler, inexpensive laboratory method that measures quercetin and a related substance, isorhamnetin, using only a tiny blood sample, about one drop. The method worked reliably in both mouse and human blood. We then used it to measure quercetin in mice given EMIQ, including a mouse model of DM1, and could detect the compound in all treated animals. Because the test needs only a small sample, it reduces the number of animals needed for research and could make future human studies easier.",

This study integrated time-intensity (TI), temporal dominance of sensations (TDS), electronic tongue, and LC-MS analyses to evaluate astringency in six green, black, and oolong teas. TI results indicated that green tea exhibited higher peak intensity, larger area under the curve (AUC), longer duration, and faster onset compared to oolong and black teas. TDS analysis revealed dominant sensations: \"harsh\" and \"coarse grain\" for green tea, \"smooth\" and \"dry\" for black tea, and alternating \"rough\" and \"dry\" for oolong tea. LC-MS profiling linked high astringency to anthocyanins, quercetin derivatives, and catechin oxidation products. Roughness correlated with polymerized catechins, granularity with flavanols, and dryness with oxidized polyphenols. Overall, polyphenol type and structure are key determinants of astringency intensity and sub-quality variations among tea types.",

Current treatment options remain limited, necessitating the discovery of novel diagnostic and therapeutic targets. This study aimed to identify a novel diagnostic and druggable target in the SN of PD patients. We first nominated PD risk-associated differentially expressed genes (DEGs) in the SN bulk profile (GSE7621) of PD patients using Limma, weighted gene co-expression network analysis (WGCNA), and summary-data-based Mendelian randomization (SMR). Next, three machine learning algorithms [random forest (RF), least absolute shrinkage and selection operator LASSO, and support vector machine (SVM)] were performed for the identification of central pathogenic factors among the risk DEGs in the training PD patient SN bulk profile (integrated GSE20163 and GSE20164). In addition, the diagnostic performance of the identified central pathogenic factor for PD was evaluated in GSE7621, integrated GSE20163 and GSE20164, and independent PD patient SN bulk profiles (GSE140231). In addition, the molecular and immune patterns of the central pathogenic factor were assessed in SN single-cell data from PD patients (GSE7621) were estimated by a cutting-edge analytical framework in temporal and spatial manners. Furthermore, network-based drug screening and molecular docking were subsequently performed to identify potential therapeutic agents targeting the central pathogenic factors. Finally, in vitro assays estimated the expression patterns of the central pathogenic factor. Multimerin 1 (MMRN1) was identified as an upregulated pathogenic factor predominantly expressed in neurons. Quercetin was highlighted as a promising repurposed drug candidate targeting MMRN1. This study illustrated a novel diagnostic and therapeutic target for PD, which provides novel clues into clinical applications of PD patients.",
"42395946": "ID: 42395946\nTitle: Quercetin Delivered by Mesenchymal Stem Cell-Derived Exosomes Improves Liver Fibrosis via the PI3K/Akt Signaling Pathway.\nAbstract: Liver fibrosis represents a critical stage in the progression of chronic liver diseases to cirrhosis and hepatocellular carcinoma; however, effective therapeutic options remain limited. Although quercetin, a natural flavonol, possesses potent antifibrotic properties, its clinical utility is severely hindered by poor aqueous solubility and low bioavailability. To address this limitation, we developed a nanoparticle-based drug delivery system using quercetin-loaded human umbilical cord mesenchymal stem cell (hUC-MSC)-derived exosomes (hUC-MSC-exo-Que). Leveraging the innate biocompatibility and targeting capability of exosomes, this strategy aims to improve the pharmacokinetic limitations of quercetin and amplify its therapeutic efficacy. Our results demonstrate that hUC-MSC-exo-Que significantly attenuates liver fibrosis in a carbon tetrachloride-induced mouse model, outperforming free quercetin at the equivalent dose. This enhanced efficacy is attributed to the superior inhibition of hepatic stellate cell activation, as confirmed by in vitro studies. The engineered exosomes exhibited a sustained drug release profile (up to 48 h) and maintained excellent stability for at least 1 week. Integrating network pharmacology with experimental validation, we identify the antifibrotic mechanism involving potent inhibition of the PI3K/Akt signaling pathway, with hUC-MSC-exo-Que achieving markedly greater pathway suppression than free quercetin. By successfully transforming a potent but poorly bioavailable phytochemical into a targeted nanotherapeutic, we present a promising preclinical strategy for liver fibrosis treatment and demonstrate a proof-of-concept platform for hydrophobic drug delivery.",
"42396042": "ID: 42396042\nTitle: Electrosprayed Alginate-Fmoc Amino Acid Microcapsules for Quercetin Loading and Release.\nAbstract: This study presents the development of hybrid microcapsules for the loading and release of quercetin, produced by incorporation of Fmoc-Tyrosine (Fmoc-Y) or Fmoc-Proline (Fmoc-Pro) into alginate, followed by Ca2+-ion-mediated cross-linking. The microcapsules produced using this method were characterized in terms of particle size, morphology, chemical structure (FTIR), release behavior, and swelling properties. An average diameter of microcapsules loaded with quercetin was measured at 187 \u00b1 19 \u03bcm for Ca-Alginate, 154 \u00b1 14 \u03bcm for Ca-Alginate/Fmoc-Y, and 131 \u00b1 15 \u03bcm for Ca-Alginate/Fmoc-Pro. The inclusion of Fmoc-Pro or Fmoc-Y in the Ca-Alginate structure was shown by changes and shifts in the peak in FTIR. Rheological analyses revealed the flow behavior, viscoelastic properties, and shear-induced structural stability of alginate solutions used in microcapsule production. The incorporation of Fmoc-aa into alginate was intended to enhance the structural durability of the alginate matrix and thereby improve its drug release performance. Consistent with this expectation, examination of quercetin release at pH = 7.4 revealed that release from Ca-Alginate microcapsules was completed within 7 h, whereas release from the hybrid microcapsules extended to 24 h. Moreover, the zero-order model for Ca-Alginate microcapsules and the Korsmeyer-Peppas model for hybrid microcapsules were determined as the most appropriate mathematical models. The swelling behavior of the microcapsules was investigated at pH = 1.2 and 7.4. Although shrinkage occurred in the microcapsules at pH = 1.2, the spherical form was maintained in the first 7 h in hybrid and nonhybrid microcapsules. At pH = 7.4, it was observed that Ca-Alginate microcapsules were largely eroded approximately at the 6th hour, while hybrid Ca-Alginate/Fmoc-Y and Ca-Alginate/Fmoc-Pro microcapsules maintained their spherical form up to 16 h. These findings are supported by SEM analyses showing that hybrid microcapsules exhibit a more compact and less porous surface morphology compared to pure Ca-Alginate microcapsules.",

However, systematic evaluation of regional variation and hot-water brewing effects on flavonoid content and bioactivity remains limited. This study analyzed leaves from multiple regions as unprocessed tea (PT), brewed infusion (TS), and residues (TG) for flavonoid content, extraction efficiency, antioxidant activity, and metabolomic profiles. Shandong samples (P7, P6) exhibited higher total flavonoid contents (66.2, 68.6\u00a0mg/g) and extraction efficiencies (59.1%, 58.8%), with P7 exhibiting the strongest antioxidant activity. Metabolome analysis identified flavonoids as dominant metabolites, with phellodensin E enriched in infusions. KEGG enrichment revealed significant upregulation of quercetin-3-O-sulphate. In vivo bioactivity assays demonstrated that phellodensin E (20-25\u00a0\u03bcg/mL) and quercetin-3-O-sulphate (20\u00a0\u03bcg/mL) markedly reduced yolk-sac oxidative markers and neutrophil counts (P\u00a0<\u00a00.001), confirming strong antioxidant and anti-inflammatory effects.

This study aimed to develop an enzyme-responsive, fibrosis-targeted nanotherapeutic system capable of simultaneously delivering siRNA against progranulin (siPGRN) and quercetin (QT) to remodel the fibrotic microenvironment and effectively attenuate renal fibrosis. The TIMP-HDL-Nano@siPGRN&QT nanoparticles prepared in this study exhibit uniform nanoscale size (~\u2009100\u00a0nm), high encapsulation efficiency, excellent stability, and favorable biocompatibility. The MMP9-responsive modification significantly enhanced renal accumulation and fibrotic lesion targeting in vivo. Treatment with TIMP-HDL-Nano@siPGRN&QT markedly alleviated UUO-induced renal injury, apoptosis, and fibrosis, outperforming free drug. Transcriptomic and mechanistic analyses revealed that the therapeutic effects were mediated through disruption of the PGRN-PPAR\u03b1 interaction, restoration of PPAR\u03b1 signaling, and subsequent inhibition of NF-\u03baB-driven inflammatory pathways. Furthermore, the nanoparticles suppressed pro-inflammatory M1 macrophage polarization and promoted M2 polarization in a PPAR\u03b1-dependent manner.

Recent decades have shown that targeting sodium-glucose cotransporters (SGLTs) especially renal SGLT2 can reduce glucose levels independently of insulin and, crucially, deliver cardio-renal benefits that extend beyond glycaemic control. Yet, despite the clinical success of synthetic \"gliflozins\", gaps remain, adverse events, incomplete inhibition of renal glucose reabsorption, and limited access in some health systems. This review focuses on two quercetin glycosides quercetin-3-O-glucoside (isoquercitrin) and quercetin-3-O-rutinoside (rutin) as potential SGLT-focused modulators. This study employed a narrative mechanistic review approach integrating published experimental evidence, physicochemical structure-activity relationship (SAR) analysis, and exploratory molecular docking to examine potential SGLT-related interactions and complementary glucose-regulatory pathways of Q3G and rutin. We synthesise mechanistic evidence suggesting that Q3G and rutin may modulate SGLT-related pathways through intestinal SGLT1 interaction, regulation of renal SGLT2 expression, and complementary glucose-regulatory mechanisms. However, direct inhibition of human SGLT2 transport activity has not yet been experimentally demonstrated, and current evidence predominantly may indicate indirect pathway modulation rather than gliflozin-like transporter inhibition. Contradictory findings across assay systems are discussed in relation to structure-activity relationships shaped by glycosylation. We further examine pharmacokinetics, tissue exposure plausibility, and translational feasibility, and propose a stepwise development roadmap emphasising transporter-specific assays, quantitative target engagement, and clinically meaningful biomarkers. Q3G and rutin may exhibit putative SGLT-relevant activity within a broader polypharmacological framework; however, direct transporter-specific inhibition and clinically relevant renal exposure remain to be established through future functional and translational studies.",

Recent research has emphasized that mosquitoes must coordinate their reproductive output and immune defenses under limited energy and nutritional conditions, forming a tightly regulated trade-off. This process involves complex signaling pathways and stage-specific molecular mechanisms. Key factors, such as juvenile hormone (JH), 20-hydroxyecdysone (20E), autophagy pathways, immune-regulatory genes, and metal ions, can potentially influence this equilibrium state, thereby either promoting or inhibiting the occurrence and development of mosquito-borne infectious diseases. However, the exact mechanism underlying this regulation remains unclear. This review summarizes recent findings on how these components interact at the molecular and physiological levels, with the aim of developing a rational framework for identifying potential molecular targets and developing new strategies for vector control.",

Lentivirus infection, alkaline Phosphatase/Alizarin Red S Staining, and RT-qPCR were used to evaluate the osteogenic differentiation of mesenchymal stem cells mediated by SERINC3. MicroCT, H&E, and Masson staining were performed to investigate the bone formation and bone defect repair via Serinc3 knockout (KO) mice and nude mice. RNA sequencing, Co-IP, Western blotting, and Seahorse energy metabolism analysis were performed to elucidate the regulatory mechanism of SERINC3. Here, we identify SERINC3 as a critical regulator of osteogenic differentiation of bone marrow-derived stem cells (BMSCs) and bone regeneration. SERINC3 expression was significantly upregulated during osteogenic differentiation of BMSCs and stem cells from human exfoliated deciduous teeth (SHED). Functional assays revealed that SERINC3 overexpression enhanced osteogenic differentiation, proliferation, and migration of MSCs, while Serinc3-KO impaired these processes and led to osteopenia in mice. In a calvarial defect model, Serinc3-KO mice exhibited 42% less bone volume (BV/TV) and 35% lower bone mineral density (BMD), whereas SERINC3-overexpressing BMSCs significantly improved bone repair. Mechanistically, RNA sequencing and pathway analysis revealed that SERINC3 interacts with IL32 to activate the AMPK-ULK1-autophagy axis, thereby promoting osteogenesis. Additionally, SERINC3 enhanced mitochondrial energy metabolism by upregulating tricarboxylic acid cycle enzymes (ACO1, DLAT, SDHA) and increasing oxygen consumption rates. Rescue experiments confirmed that AMPK inhibition or autophagy blockade abolished SERINC3-mediated osteogenic effects, whereas mitochondrial electron transport chain activators restored osteogenesis in SERINC3-knockdown cells. In summary, this study identifies SERINC3 as a novel regulator of bone formation that orchestrates osteogenesis through IL32-AMPK-autophagy signaling axis and mitochondrial metabolism. These findings highlight SERINC3 as a potential therapeutic target for enhancing bone regeneration and treating skeletal defects.",

Astaxanthin (AS), a natural antioxidant, has been shown to exert various biological effects, including anti-aging and anti-inflammatory effects. However, further investigation into its anti-ovarian aging mechanism is warranted. Two-month-old female mice and CTX-induced POF model mice were used. Hematoxylin and eosin staining, immunohistochemical staining, TUNEL assays, Western blotting, and qPCR analyses were employed to evaluate ovarian function and related phenotypes after astaxanthin treatment. Subsequently, network pharmacology analysis was used to elucidated potential targets. Astaxanthin intervention significantly ameliorated estrous cycle disorder in POF mice and restored serum levels of anti-M\u00fcllerian hormone (AMH) and estradiol (E2). Meanwhile, astaxanthin markedly enhanced the ovarian reserve and suppressed CTX-induced apoptosis and autophagy. Mechanistically, astaxanthin was found to modulate the CYP19A1 expression, thereby enhancing ovarian function. This study elucidates the mechanism by which astaxanthin improves ovarian function through the CYP19A1, providing potential molecular targets and therapeutic strategies for the clinical treatment of POF.",

However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.",

Cytoskeletal damage has been increasingly regarded as a contributing factor in impairing these cellular processes in cancer. Moreover, induction of cell death pathways has been linked to cytoskeletal destabilization. However, the effect of cytoskeletal disruption on cell death mechanisms in ovarian cancer (OC) remains elusive. Several natural compounds have been demonstrated to initiate cytoskeletal destabilization as a mechanism to promote cell death. We have previously shown that one such natural compound derived from marine sources, Malformin A1 (MA1), exhibits high toxicity toward both cisplatin-sensitive (A2780S) and cisplatin-resistant (A2780CP) OC cell lines. Thus, here we evaluate the impact of cytoskeletal destabilization by MA1 treatment on OC cell death by analyzing the expression levels of apoptosis, autophagy, and DNA damage-related genes. Our findings show MA1 treatment significantly downregulated key cytoskeletal proteins while also decreasing the expression of pro-apoptotic markers, suggesting alternative cell death mechanisms. Autophagy-related analyses demonstrated enhanced LC3BI to LC3BII processing, indicating autophagy activation with elevated \u03b3-H2AX levels confirming substantial DNA damage in MA1-treated cells. Notably, MA1 was able to induce pyroptotic cell death, as evidenced by increased caspase-1 expression. Moreover, molecular docking analysis revealed that MA1 displayed the strongest binding affinity for vimentin, GAPDH, and \u03b2-tubulin, providing mechanistic insights into its ability to disrupt cytoskeletal integrity and induce nonapoptotic cell death through multiple pathways, highlighting MA1's potential as a promising therapeutic candidate.",

Quercetin (QR), a natural flavonoid, exerts antioxidant and anti-inflammatory effects by modulating the Nrf2-Keap1 pathway and shows neuroprotective potential in various neurological disorders. In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI, further highlighting the pivotal role of the Nrf2-Keap1 pathway in TBI treatment. However, the poor blood-brain barrier (BBB) permeability and low bioavailability of QR hinder effective brain-targeted delivery and limit its clinical translation. To address these challenges, we developed CAQK peptide-modified, reactive oxygen species (ROS)-responsive nanoparticles (C-PPS/Q), using PPS120 as the core for targeted QR delivery. C-PPS/Q exhibited ROS-triggered QR release, significantly enhanced HT22 cell uptake in\u00a0vitro, reduced ROS levels and apoptosis. In a TBI mouse model, C-PPS/Q specifically accumulated at the lesion site, prolonged the half-life of QR, demonstrated excellent biocompatibility, preserved BBB integrity, attenuated neuroinflammation, inhibited aberrant Nrf2-Keap1 pathway activation, and markedly improved neurological function. Collectively, C-PPS/Q nanoparticles effectively mitigate secondary brain injury after TBI and represent a promising brain-targeted therapeutic strategy for TBI management.",

"42400730": "ID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.",

Hence, employing multiple cell death pathways is an emerging strategy in overcoming treatment resistance in OSCC. We investigate here the effect of heteronemin, a marine sesterterpenoid isolated from sponges, for its anti-cancer potential, hypothesizing that it can induce non-apoptotic cell death pathways to overcome apoptosis-resistant cells and elucidate the underlying mechanisms involved. Our results show that heteronemin significantly kills cancer cells via the induction of the intrinsic apoptotic pathway. It also triggers ferroptosis, down-regulating glutathione peroxidase 4 (GPX4) and upregulating markers of lipid peroxidation such as 4-hydroxynonenal and malondialdehyde. We demonstrate that increasing reactive oxygen species generation plays a central role in triggering these pathways. ensuring the death of the cancer cells despite a compensation attempt via inducing autophagy and modulating Nrf2. Our study is the first to demonstrate the complex but interesting role of heteronemin in killing OSCC cells: inducing apoptosis and switching to ferroptosis as the cells attempt to survive. It also inhibits protective autophagy, leaving OSCC cells incapable of protecting themselves from imminent death. This complex mechanism adds to the existing knowledge on the mechanism of heteronemin as a strong therapeutic compound to treat OSCC cells.",

A total of 9 genes were first identified by intersecting the differential genes of the GSE15471 and GSE62165 datasets with 248 Neddylation genes from the Reactome Pathway Database. The association between disease-free survival and the 9 genes in patients with PDAC was analyzed. Analysis using The Cancer Genome Atlas, Gene Expression Omnibus and Gene Expression Profiling Interactive Analysis databases revealed that COPS8 was highly expressed in patients with PDAC, and PDAC tissues exhibited significantly higher COPS8 expression levels compared to those found in paracancerous tissues. Finally, the above results were verified by cellular experiments, reverse transcription-quantitative PCR, Western blotting and immunohistochemistry. The mRNA expression levels of COPS8 were significantly elevated in the pancreatic cancer cell lines PANC-1and MIA PaCa-2 compared to those in HPNE normal pancreatic cells, and the protein expression levels of COPS8 were also significantly elevated in the pancreatic cancer cells PANC-1 and MIA PaCa-2. COPS8 protein was significantly increased in cancer tissues of patients with pancreatic cancer compared to paracancerous tissues. The proliferative, migratory and invasive abilities of PANC-1 and MIA PaCa-2\u202fcells were significantly reduced after knockdown of COPS8. The results showed that knockdown of COPS8 in PANC-1 and MIA PaCa-2\u202fcells decreased Microtubule-associated proteins 1A/1B light chain 3B (LC3\u2161/LC3\u2160), while Sequestosome 1 (P62/SQSTM1) expression was elevated.

"42401068": "ID: 42401068\nTitle: Dihydroberberine regulates the ferroptosis-autophagy positive feedback loop in colorectal cancer by targeting PANX2.\nAbstract: Colorectal cancer (CRC) is one of the most common malignancies worldwide and remains a major clinical challenge, underscoring the urgent need for novel therapeutic targets and treatment strategies. Ferroptosis, a form of cell death triggered by iron-dependent lipid peroxidation, is emerging as a promising new anti-cancer therapeutic strategy. This study aims to identify a key target regulating the ferroptosis process in CRC, screen for small molecule modulators against this target, and elucidate their potential anti-tumor mechanisms. We developed a Drug Discovery Strategy for Targeted Ferroptosis Therapy Based on Bioinformatics-Machine Learning Integration for the Treatment of CRC (DDTF-BMLI-CRC), aiming to identify key ferroptosis regulators. The functional role of this factor in CRC and ferroptosis was validated through knockdown and overexpression techniques, establishing it as a potential therapeutic target. Subsequently, candidate compounds were screened from natural product and FDA databases using a dual-scoring model combining machine learning and deep learning. The direct binding of candidate compounds to target proteins was validated through molecular docking, molecular dynamics simulations, DARTS, CETSA, and SPR techniques. Finally, a series of in vitro and in vivo experiments were conducted to systematically evaluate their anti-tumor effects and potential mechanisms. PANX2 was identified as a key ferroptosis-suppressing gene in CRC. We discovered the natural small molecule dihydroberberine (dhBBR) to be a potent and direct inhibitor of the PANX2 protein. In vitro, dhBBR significantly inhibited the proliferation, migration, and invasion of CRC cells while inducing ferroptosis. In vivo, dhBBR effectively suppressed xenograft tumor growth. Mechanistic studies revealed that dhBBR-induced ferroptotic stress activates autophagy, which in turn promotes GPX4 degradation, thereby amplifying the ferroptotic effect and establishing a ferroptosis-autophagy positive feedback loop. Crucially, PANX2 knockdown largely abolished the additional anti-tumor effect of dhBBR, and dhBBR did not further suppress tumor growth beyond PANX2 knockdown alone. This study demonstrates that PANX2 knockdown suppresses CRC progression by inducing ferroptosis. Furthermore, we identified dhBBR for the first time as a PANX2-targeting small-molecule inhibitor. Our research reveals a novel therapeutic strategy targeting the PANX2-mediated ferroptosis-autophagy axis and provides a highly promising candidate compound for the treatment of CRC.",

The role of aggrephagy-selective autophagy of protein aggregates-in shaping neutrophil heterogeneity and LIHC progression remains poorly understood. We integrated scRNA-seq (183,671 cells), spatial transcriptomics, and bulk datasets (TCGA, GSE39791). Neutrophils (n=12,547) were re-clustered into six subsets, and aggrephagy activity was quantified via UCell scores. Analysis included pseudotime trajectories, cell-cell communication, metabolic scoring, and machine-learning-based feature selection, followed by in vitro functional validation. Aggrephagy activity was significantly elevated in tumor tissues compared with adjacent normal tissues (P < 0.001) and showed strong cell-type specificity, with TANs among the most enriched populations. High-aggrephagy neutrophils exhibited an undifferentiated state, preferential tumor enrichment, and a positive correlation with transcriptomic risk scores. Trajectory analysis positioned these cells at an early differentiation branch and revealed dominant neutrophil-to-stroma signaling through the CCL3-CCR1, SPP1-CD44, and ANXA1-FPR1 axes. Metabolically, high-aggrephagy neutrophils displayed enhanced inflammatory and epithelial mesenchymal-transition programs alongside suppressed oxidative phosphorylation. Integrative network analysis identified a five-gene diagnostic panel (SQSTM1, WDFY3, DOCK4, CD177, LIMK2) with robust performance across bulk cohorts (AUC 0.83-0.91). Among these, LIMK2 marked a highly interactive neutrophil subset and functionally promoted tumor cell proliferation, survival, migration, and invasion in vitro. Aggrephagy is associated with a pro-tumorigenic, metabolically reprogrammed neutrophil state in LIHC. The LIMK2-centered gene panel provides a robust framework for subset identification and nominates candidate targets for future autophagy- and neutrophil-directed studies.",
"42401166": "ID: 42401166\nTitle: Aloin suppresses cancer cell growth via autophagy-promoted NEDD8 de-NEDDylation to target GPX4 for ferroptosis induction.\nAbstract: Aloin (ALO), an anthraquinone derived from Aloe vera, exhibits antitumor activity; however, its precise mechanisms of action remain unclear. In this study, in silico molecular docking analysis first revealed that Aloin (ALO) bound effectively to ferroptosis-related proteins (SLC7A11, GPX4, ACSL4, and TFR1). Subsequently, in vitro ALO treatment triggered ferroptosis hallmarks in human cervical cancer cell line Hela and mouse colon cancer cell line MC38 at both transcriptional and protein levels-downregulating SLC7A11/GPX4, upregulating ACSL4/TFR1, with Fe2+/ROS accumulation, GSH depletion, and ferroptosis-specific mitochondrial cristae loss. Furtherly, ALO inhibited cancer cell proliferation, migration, and invasion, effects that were reversed by the ferroptosis inhibitor Ferrostatin-1. Concurrently, ALO induced autophagy, as evidenced by increased levels of LC3, LaminB1, and ULK1, decreased levels of P62, and TEM-visualized autophagosomes. Notably, the autophagy inhibitor chloroquine reversed ALO-induced ferroptosis, NEDD8 downregulation, and NEDP1 upregulation, linking ALO-induced autophagy to NEDD8 de-NEDDylation. Genetic and pharmacological perturbation of the NEDD8 pathway confirmed this: NEDD8 inhibition enhanced, while NEDP1 knockdown attenuated, ALO-induced ferroptosis. Co-immunoprecipitation and laser-scanning confocal microscope confirmed a direct NEDD8-GPX4 interaction diminished by ALO, positioning GPX4 as a key effector. In in vivo study, ALO effectively inhibited cancer cell growth in a murine colon carcinoma MC38 xenograft models, while exhibiting no obvious toxicity or side effects in mice. Moreover, ALO exhibited the same regulatory effects and trends on ferroptosis-related proteins in vivo as those in vitro. In summary, this study reveals a novel mechanism that ALO-induced autophagy promotes NEDD8 de-NEDDylation, driving ferroptosis via the NEDD8-GPX4 axis to suppress cancer cell growth.",

Using Tapt1 knockout and knock-in mice, we indicate that TAPT1 localizes to the endoplasmic reticulum and that Tapt1 deletion causes neonatal lethality due to atelectasis-induced respiratory distress. We further reveal that TAPT1 interacts with the ATP-binding cassette transporter A3 (ABCA3), thereby regulating autophagy-lysosomal degradation of ABCA3. ABCA3 insufficiency reduces surfactant lipids, leading to defective lamellar body formation and surfactant production. This study presents a hitherto unrecognized pathway for ABCA3 protein degradation. Our findings may advance the understanding of genetic determinants of neonatal respiratory distress syndrome, providing valuable insights into the treatment of lung surfactant disorders.",

Tanshinone IIA (TIIA), a multi-target bioactive compound derived from Salvia miltiorrhiza, has shown potential in retinal disease treatment. In this study, we investigated the therapeutic effects and underlying mechanisms of TIIA on choroidal neovascularization (CNV) using Vldlr knockout (Vldlr-/-) mice as an nAMD model. TIIA was administered intraperitoneally for 8 weeks, and CNV progression and vascular leakage were evaluated by OCT and FFA, while outer blood-retinal barrier (oBRB) integrity was assessed by immunofluorescence staining. Proteomics analysis combined with western blotting was used to explore the molecular mechanisms. Our results showed that TIIA significantly reduced CNV area and leakage, and restored oBRB integrity by upregulating tight junction proteins ZO-1 and Occludin in the RPE/choroid complex. Mechanistically, TIIA inhibited angiogenesis via suppression of the PLC\u03b3/ERK1/2 signaling pathway. In addition, proteomics analysis revealed enhanced cholesterol efflux, intermediate filament reorganization, and decreased autophagy-related proteins across the retina, RPE/choroid complex, and serum. Collectively, these findings demonstrate that TIIA alleviates nAMD pathology through multi-target mechanisms, including inhibition of angiogenesis, restoration of barrier function, metabolic reprogramming, and modulation of autophagy, highlighting its potential as an alternative therapeutic strategy for nAMD.",

This ethnopharmacological knowledge provides a rich resource for discovering novel anti-inflammatory agents. This review critically evaluates the evidence for the modulation of the Receptor for Advanced Glycation End-products (RAGE) signaling pathway by natural products derived from traditional medicines, aiming to connect this traditional knowledge with modern molecular pharmacology. A comprehensive literature review was performed using the PubMed database. The search focused on keywords such as \"RAGE,\" \"natural products,\" and \"traditional medicine\" to identify studies detailing the mechanistic interactions between natural compounds and the RAGE pathway. Natural products, including polyphenols, terpenoids, and alkaloids, modulate the RAGE axis through several key mechanisms: (1) inhibiting the formation of Advanced Glycation End-products (AGEs); (2) directly blocking the RAGE-ligand interaction; (3) downregulating RAGE expression; and (4) suppressing downstream inflammatory signaling. Compounds like quercetin, ursolic acid, and berberine have demonstrated significant activity in various preclinical models. Natural products represent a profound source of multi-target RAGE modulators, offering a potential therapeutic advantage over synthetic single-target drugs. While challenges in bioavailability and clinical translation remain, the data strongly validates the ethnopharmacological approach. Future progress depends on integrating this traditional wisdom with modern technologies to unlock the full clinical potential of these compounds.",

Irisin, an exercise-dependent myokine, serves as a critical peripheral-to-central signaling mediator modulating brain function and anxiety-like behavioral phenotypes. This review systematically integrates current preclinical evidence illustrating how irisin regulates anxiety through multi-level neural mechanisms. Irisin suppresses microglial NF-\u03baB/STAT3-mediated neuroinflammation, enhances prefrontal-hippocampal synaptic plasticity via BDNF upregulation and AMPK/mTOR-related autophagy, and improves gut-brain axis homeostasis by stabilizing intestinal barrier integrity and reshaping microbial composition. Crucially, we propose a context-dependent therapeutic window model to reconcile contradictory pro-anxiogenic and anxiolytic findings across stress severity and pathological stages, resolving existing controversies in this field. We further summarize key unresolved limitations, including ambiguous central receptor identity, peripheral-central dissociation and sex-dependent heterogeneity.

Identifying anti-arthritic agents that concurrently protect against ILD is clinically significant. Sinomenine (SIN), a natural alkaloid used clinically to treat RA, shows potential anti-fibrotic activity, but its efficacy and mechanism in RA-ILD remain unclear. Here, integrative bioinformatic analyses identified ILD-associated signature characterized by upregulated CHRNA7 (encoding \u03b17nAChR) and downregulated GLUL, specifically in pulmonary fibroblasts and myofibroblasts, and GLUL was a crucial mediator between RA and ILD. In the adjuvant-induced arthritis (AIA) model with pulmonary inflammatory and fibrotic remodeling, the phenotype that recapitulates early-stage RA-ILD, pulmonary ACh and \u03b17nAChR expression were observed upregulated. SIN ameliorated arthritis and pulmonary lesions, suppressed pulmonary \u03b17nAChR signaling, inhibited AKT/FOXO3 activation, restored GLUL expression and improved autophagy-related changes in this model. Microscale thermophoresis (MST), molecular docking and molecular dynamics simulation supported a direct binding between SIN and \u03b17nAChR. In vitro, \u03b17nAChR activation with PNU-282987 promoted fibroblast-to-myofibroblast transition (FMT), whereas its genetic knockdown inhibited FMT, suppressed AKT/FOXO3 activation, and restored GLUL expression in TGF-\u03b2-stimulated MRC-5 cells. We confirmed direct FOXO3 binding to the GLUL promoter by ChIP-qPCR. SIN inhibited FMT and regulated the AKT/FOXO3/GLUL axis in an \u03b17nAChR-dependent manner. Pharmacological inhibition and siRNA-mediated knockdown of GLUL abolished SIN-mediated regulation of mTOR-autophagy signaling and FMT. Our findings identify the \u03b17nAChR/AKT/FOXO3/GLUL axis as a novel fibrotic driver and highlight SIN as a potential therapeutic candidate to inhibit RA-ILD by targeting this axis.",

Epstein-Barr virus (EBV) is associated with many malignancies such as B-cell lymphoma (B-CL). However, the role and mechanism of EBV in regulating ferroptosis to participate B-CL development remains poorly understood. Here, we displayed that the expression of breast cancer gene 1 (BRCA1) was downregulated in EBV-infected B-CL cells and tissues. EBV-encoded nuclear antigen 1 (EBNA1) was responsible for the BRCA1 downregulation. Moreover, the expression of BRCA1 was negatively related to that of glutathione peroxidase 4 (GPX4) in B-CL tissues. EBNA1 inhibited ferroptosis by inducing GPX4 expression via BRCA1 inhibition. Mechanistically, BRCA1 bound to GPX4 and promoted GPX4 degradation via the autophagy pathway, thus increasing the sensitivity of EBV-positive B-CL cells to ferroptosis. Furthermore, BRCA1 depletion suppressed ferroptosis in B-CL cells, and the knockdown of endogenous GPX4 in EBV-infected Daudi cells restored ferroptosis sensitivity and markedly suppressed xenograft tumor growth. The findings unveil a novel mechanism by which EBV inhibits ferroptosis for its contribution to the progression of B-CL, identifying a new pathway of BRCA1-mediated GPX4 destabilization. The results provide a new direction for the viral tumorigenicity and potential treatment targets of EBV-related B-CL.",

The nanocarriers were synthesized via a double-emulsion method and comprehensively characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and dynamic light scattering (DLS) with zeta potential analysis. The optimized G/MMT/CeO2@QC nanocarriers exhibited a uniform nanoscale size (39.3\u00a0nm) and a high negative zeta potential (-\u200938.6 mV), indicating excellent colloidal stability. Incorporation of MMT and CeO\u2082 significantly enhanced drug loading and encapsulation efficiency (43.0% and 84.5%, respectively) compared to the MMT-free G/CeO\u2082@QC system, due to synergistic effects of layered silicate confinement, gelatin-mediated hydrogen bonding, and CeO2-driven Lewis acid-base coordination. In vitro release studies demonstrated pronounced pH sensitivity, with sustained release at physiological pH (60% at pH 7.4 after 96\u00a0h) and accelerated release under tumor-mimicking acidic conditions (95% at pH 5.4). To further interpret the release kinetics, machine learning-assisted, shape-constrained data analysis was employed to provide time-resolved and physically consistent insights into pH-dependent release behavior. Kinetic modeling confirmed Higuchi and Korsmeyer-Peppas-controlled diffusion mechanisms. Cytocompatibility and anticancer activity were evaluated using the MTT assay on A549 lung cancer cells and L929 fibroblasts. Blank nanocarriers were non-toxic (>\u200995% cell viability), while drug-loaded nanocarriers achieved selective cytotoxicity (A549 viability reduced to 55% with 93% viability in L929 cells), outperforming free QC. Overall, this tri-component hybrid system provides a multifunctional nanoscale platform with controlled drug release, high encapsulation efficiency, and tumor-selective cytotoxicity, demonstrating strong potential as a pH-responsive nanocarrier for lung cancer therapy.",

To address this, cultures of the main glial cell types in the central nervous system (CNS), including astrocytes, microglia, oligodendrocyte progenitors, and differentiating oligodendrocytes, were created to examine the impact of an in vitro hypoxia-ischemia (HI) model on autophagy. The HI insult was mimicked by applying temporal oxygen-glucose deprivation (OGD). Since neonatal hypoxic-ischemic insults primarily affect the brain's white matter, the study predominantly focused on oligodendrocytes at different stages of maturation: progenitor cells versus cells that express myelin components (e.g. MBP). The results show that the different glial fractions exhibit varying sensitivity to the applied conditions. Maturing oligodendrocytes were found to be more sensitive to OGD conditions than the progenitor fraction. The OGD procedure was proven to impact the expression of autophagy markers, indicating the activity of this process in response to injury. Western blot analysis of oligodendrocyte progenitor cells (OPCs) showed that the autophagy substrate marker p62 increased after six hours, which may suggest transient inhibition and subsequent activation of autophagy. To verify the involvement of autophagy in the differentiation of neonatal oligodendrocytes, the process was modulated using chloroquine (CQ) treatment. CQ is recognised as an inhibitor of autophagic flux because it disrupts lysosomal acidity and prevents the breakdown of autophagosomes. CQ treatment resulted in the accumulation of autophagosomes. The results suggest that abnormalities in the functioning of glial cells, particularly oligodendrocytes, in response to hypoxic-ischaemic (HI)-like conditions might be associated with altered autophagic flux in response to cellular stress. Transient alterations in autophagy were observed within 24\u00a0h of limiting oxygen and glucose supply, and these alterations may contribute to subsequent disorders in oligodendrocyte differentiation. This is recognised as one of the major issues in the pathogenesis of neonatal hypoxia-induced damage. Therefore, modulation of autophagy could be a promising therapeutic approach to prevent these adverse changes.",

Nutrition, particularly dietary protein content, profoundly impacts honeybee health and reproduction. Yet, the molecular mechanisms connecting diet composition and gene expression in honeybee eggs remain underexplored. In this study, we investigate the intricate relationship between diet, gene expression, and honeybee egg development. Using RNA-seq analysis, we explore the effects of different protein-to-carbohydrate (P: C) ratios in honeybee diets on differential gene expression in the eggs laid by the queen and potential associated molecular responses. Our research identifies 1007 differentially expressed genes (DEGs) across various dietary conditions, highlighting the pivotal role of nutritional composition in shaping gene expression during egg development.Cluster analysis revealed two DEG profiles corresponding to low protein diets (LPD) and high protein diets (HPD). LPD conditions upregulate genes linked to protein catabolism, autophagy, and ubiquitin-mediated proteolysis, indicating potential cellular responses to nutritional stress. Conversely, HPD conditions upregulate genes related to RNA processing, spliceosome activity, and the MAPK signalling pathway, suggesting normal cellular development.Notably, the Hippo signalling pathway exhibits distinct gene regulation patterns under LPD and HPD conditions, potentially influencing cellular growth and differentiation in response to nutrient availability.Our findings underscore the critical role of nutrition in honeybee health and reproduction, providing insights into optimizing honeybee diets for colony health and resilience. As honeybee populations confront challenges from changing environmental conditions and resource availability, understanding these molecular responses is crucial for their effective management and conservation as essential pollinators. This study establishes a foundation for further investigations into the functional consequences of these molecular responses at the individual level and their broader implications for honeybee colony development and health.",

Using binding energy data from molecular docking with TBC1 domain family member 2 (TBC1D2) as the target, we rationally designed compound G2 featuring a piperazine moiety. Target binding was validated via a competitive immunofluorescence assay. The binding affinity of G2 was determined by surface plasmon resonance, yielding a dissociation constant (KD) of 0.4\u202f\u03bcM. Functional evaluation of G2 determined its aqueous solubility to be 0.3\u202fmg/mL, with a half-maximal inhibitory concentration value of 80\u202f\u00b1\u202f20\u202fnM and a selectivity index of 23.1 in HCCLM3 cells. Subsequent mechanistic investigations revealed that this selectivity arose from the heightened responsiveness of TBC1D2 expression to G2 in HCCLM3 cells, thereby inducing selective autophagic cell death. In HCCLM3 xenograft mouse models, G2 showed excellent hepatic retention. G2 monotherapy (58.2% tumor growth inhibition) and its combination with sorafenib (70.9%) exerted superior antitumor activity versus sorafenib monotherapy (52.8%), with favorable safety. Collectively, our findings establish G2 as a promising therapeutic candidate for surmounting sorafenib resistance, characterized by selective antitumor activity against malignant hepatocellular carcinoma.",

Quercetin, a naturally occurring flavonoid with established cardioprotective properties, has been reported to inhibit VSMC dysfunction, yet the underlying molecular mechanisms remain incompletely defined. Here, we demonstrate that quercetin dose-dependently suppresses TGF-\u03b21-induced proliferation and migration of human aortic VSMCs. Mechanistically, quercetin attenuates TGF-\u03b21-mediated phosphorylation of Smad2/3 and markedly reduces expression of matrix metalloproteinase-9 (MMP-9). Using the selective TGF-\u03b2 type I receptor inhibitor SB431542, we establish that MMP-9 expression in VSMCs is regulated through the canonical Smad2/3 signaling pathway. Rescue experiments with MMP-9 overexpression reversed the anti-proliferative and anti-migratory effects conferred by TGF-\u03b2 receptor blockade, confirming MMP-9 as an essential downstream effector. These findings delineate the TGF-\u03b21/Smad2/3/MMP-9 signaling axis as a molecular target of quercetin in VSMCs and provide mechanistic rationale for quercetin-based therapeutic strategies in vascular remodeling diseases.",
"42402325": "ID: 42402325\nTitle: ROS as a powerful instrument for the advanced cancer prevention and management: Facts and outlook.\nAbstract: Reactive oxygen species (ROS) play a complex dual role in cancer biology. At physiological levels, ROS act as signaling molecules that drive tumorigenesis, metastasis, and therapy resistance by activating oncogenic pathways, such as NF-\u03baB and PI3K/AKT, and fostering an immunosuppressive microenvironment. Conversely, excessive ROS accumulation overwhelms antioxidant defenses, triggering oxidative stress that can selectively eliminate tumor cells. Consequently, manipulating the delicate redox equilibrium has emerged as a pivotal strategy for cancer treatment. This review systematically examines the multifaceted functions of ROS, bridging the gap between fundamental redox biology and clinical application within the Predictive, Preventive, and Personalized Medicine (3PM) framework. Beyond molecular mechanisms, we evaluated the rationale for utilizing mitochondrial redox signatures as intrinsic biological sensors to identify suboptimal health conditions (SHC) and prevent the health-to-disease transition. We elucidate the regulatory networks governing ROS production and elimination, highlighting their dual function in promoting genomic instability versus inducing distinct cell death modalities, including apoptosis, autophagy, necroptosis, and ferroptosis. Special attention is given to ROS-mediated remodeling of the tumor microenvironment (TME), where oxidative stress facilitates immunosuppression. Importantly, we provide expert recommendations on integrating digital health monitoring and patient stratification into clinical oncology. By emphasizing mitochondrial rejuvenation and individualised protection, this review discusses how proactive interventions can restore homeostasis and improve long-term outcomes, offering a cost-effective alternative to reactive treatments.",
"42402587": "ID: 42402587\nTitle: \u03b1-Synuclein triggers intercellular nanotubes formation to prevent apoptosis in astroglia by promoting stemness.\nAbstract: Astrocytes play a significant role in neuroprotection by internalizing neurodegenerative aggregates and facilitating their degradation. Recent studies indicate that \u03b1-Synuclein (\u03b1-SYN) protofibrils promote the transfer of pathogenic aggregates and dysfunctional mitochondria between astroglia via tunneling nanotubes (TNTs), which enhances cell survival and resistance to apoptosis. However, the underlying mechanism of TNT-driven apoptosis resistance remains unclear. We find that \u03b1-SYN protofibrils induce aberrant mitochondria with decreased membrane potential (\u03a8m) and promote dynamic actin remodeling by relocating phosphorylated focal adhesion kinase (pFAK) to the nucleus, which triggers TNT formation in human astrocytoma cell lines and primary murine astrocytes. The important novel finding of this study is that pFAK in the nucleus co-localizes with Nanog, a crucial transcription factor for preserving stemness, and the interaction between pFAK and Nanog is critical for promoting p53 degradation via Mdm2-mediated ubiquitination and upregulating autophagy, thereby supporting the survival of astroglia exposed to toxic \u03b1-SYN protofibrils. ROCK inhibitor y-27632 also drives TNT-formation via pFAK translocation to the nucleus, colocalizes with Nanog, and enhances stemness-related gene expression. Inhibiting TNT with the actin depolymerizing agent cytochalasin-D prevents pFAK co-localization with Nanog in the nucleus and fails to protect cells from \u03b1-SYN-induced apoptosis. Nanog knockdown does not degrade p53 and hinders cell rescue from apoptosis. Furthermore, these transient TNTs transfer mitochondria to adjacent cells, potentially helping maintain metabolic stability. This study reveals that the TNT formation pathway promotes pFAK-Nanog interaction in the nucleus, leading to p53 degradation, which protects astroglia against \u03b1-SYN proteotoxicity and prevents apoptosis.",

Regorafenib plus anti-PD-1 is a new therapeutic option for patients with colorectal cancer liver metastases (CRCLM). However, a considerable number of patients have not benefited from it. In this study, KRAS mutation was identified associated with resistance to regorafenib plus anti-PD-1 in CRCLM. Dihydroartemisinin (DHA), a clinically approved anti-malaria agent, was verified to selectively downregulate KRASG12D mutant with no discernible influences on wild-type KRAS, which is consistent with the higher sensitivity of KRAS-mutant CRC cells and organoids to DHA treatment. In preclinical KRASG12D CRCLM models, DHA substantially potentiated the therapeutic efficacy of regorafenib plus anti-PD-1 by remodeling the tumor immune microenvironment, including enhancing the cytotoxicity of CD8+ effector T cells and promoting pro-inflammatory macrophage polarization. Mechanically, DHA could restore interferon response that was impaired by oncogenic KRAS mutations, and inhibit ERBB signaling activation induced by regorafenib. Collectively, these findings support DHA as a potential adjunct to regorafenib plus anti-PD-1 for KRASG12D CRCLM and suggest a therapeutic strategy with translational potential for KRAS-driven malignancies.Black arrows: Mutant KRAS can impair IFN response to inhibit CD8+ T cells anti-tumor immune response, thus attenuating the efficacy of PD-1 mAb therapy. Red arrows: DHA can inhibit mutant KRAS expression by promoting autophagy-lysosome pathway. Orange arrows: Regorafenib plays a role of anti-angiogenesis, but also probably induces ERBB signaling activation, which can inhibit IFN response via upregulating p-Erk1/2 and p-Akt, thus causing resistance to regorafenib treatment. Green arrows: The treatment of DHA can drive macrophages polarization to pro-inflammation phenotype (M1-like), probably via the enhancement of TNF\u03b1 expression.

Triple Negative Breast Cancer (TNBC), which lacks the expression of the hormonal Estrogen Receptor (ER) and Progesterone Receptor (PR), amplification of Human Epidermal Growth Factor Receptor 2 (HER2), is not responsive to the hormonal therapy. Currently, available chemotherapy and radiotherapy cause severe side effects; therefore, there is an urgent need for new therapeutic choices for TNBC. Acridocarpus orientalis is used in folk medicine to treat several health conditions. Here, evaluated the anti-cancer activity of Acriodocarpus orientalis Ethanolic Extract (AOEE) against two TNBC (MDA-MB-231 and Hs578T) and one luminal A (MCF-7) cell lines, and investigated the molecular mechanisms underlying its anticancer activity. The results revealed that AOEE inhibited cell proliferation of the three cell lines in a concentration- and time-dependent manner. The anti-proliferative effect of AOEE was found to be concomitant with the induction of cell cycle arrest at the G1/S phase. These changes were associated with upregulation of p21WAF1 and p27 Kip1, downregulation of PCNA, Cyclin D1, phospho-Rb. Moreover, AOEE induces abortive autophagy through upregulation of autophagy related proteins LC3-II, Beclin-1, and p62. Also, p16-dependent senescence was induced in AOEE treated MDA-MB-231 cells confirmed by senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) expression in the treated cells. AOEE induced activation of ERK and p38 pathways, which might be involved in autophagy and senescence induction.

This study evaluated the phytochemical profile of Tridax procumbens ethanol extract (TP) and validated its multi-target, systemic organoprotective efficacy against cerebral I/R-induced cardiohepatorenal oxidative injury. TP constituents were identified using LC-MS profiling. Its in-vitro antioxidant metrics were quantified via DPPH, reducing power, and H2O2 scavenging assays. For in-vivo assessment, Wistar rats were subjected to 30\u00a0min of global cerebral ischemia via bilateral common carotid artery occlusion (BCCAO), followed by reperfusion. TP (20-80\u00a0mg/kg, i.p.) and quercetin (20\u00a0mg/kg, i.p.) was administered immediately at reperfusion. After 24\u00a0h, malondialdehyde (MDA) and reduced glutathione (GSH) were mapped across the heart, liver, and kidneys, alongside brain histopathology. LC-MS profiling identified 10 major phenolics and flavonoids, notably luteolin (37.32%), kaempferol (21.41%), and resveratrol (14.65%). In vitro, TP demonstrated significant antioxidant prowess, achieving 56.8% DPPH inhibition (50\u00a0\u00b5g/mL) and 86.98% H2O2 scavenging (10\u00a0\u00b5g/mL). In vivo, BCCAO caused severe cerebral injury and a systemic surge in lipid peroxidation paired with systemic GSH depletion. TP treatment significantly (P\u2009<\u20090.05) minimized multi-organ MDA accumulation, dose-dependently restored endogenous GSH pools across all harvested peripheral tissues, and preserved neuro-architectural integrity while reversing cerebral necrosis. TP exerts powerful multi-systemic protection by mitigating distant-organ oxidative bankruptcy and neuro-structural collapse, showcasing its potential as a natural therapeutic compound for complex vascular injuries.",

Increasing evidence suggests that functional coordination among membrane-bound organelles, including mitochondria, the endoplasmic reticulum (ER), lysosomes, peroxisomes, and the Golgi apparatus, contributes to cellular homeostasis during aging. However, the mechanisms linking kinase signaling to specific inter-organelle contact sites or communication pathways remain incompletely defined. In this review, we discuss current evidence linking major metabolic and stress-responsive kinases, including AMPK, pyruvate dehydrogenase kinases (PDKs), mTOR, AKT, and PERK, to organelle coordination in aging and age-related diseases. These kinases regulate mitochondrial dynamics, metabolic flux, calcium and lipid handling, autophagy, lysosomal function, proteostasis, and vesicular trafficking. In some contexts, kinase signaling intersects with defined organelle interfaces, such as mitochondria-associated ER membranes, whereas in many cases the effects on inter-organelle communication are indirect or inferred from broader changes in organelle function. We further discuss how kinase dysregulation may contribute to age-associated defects in mitochondria-ER, mitochondria-lysosome, mitochondria-peroxisome, and ER-Golgi coordination in neurodegeneration, cardiometabolic disease, cellular senescence, and inflammaging. By distinguishing direct contact-site regulation from indirect functional coordination, this review highlights kinase-regulated organelle communication as an emerging, but still incompletely resolved, framework for understanding cellular decline during aging.",

Here, we identify CAMKV as an interferon-stimulated gene (ISG) that drives the macroautophagic/autophagic degradation of RABV phosphoprotein (P), thereby potently suppressing viral replication in vitro. Notably, in vivo overexpression of CAMKV significantly delays disease progression in mice challenged with a street strain of RABV. Mechanistically, CAMKV interacts with both RABV P and SQSTM1, promoting SQSTM1-mediated selective autophagic clearance of P and thereby restricting RABV transcription and replication.

Although its immunomodulatory and anticancer properties have been extensively investigated, an integrated framework connecting traditional therapeutic principles with modern molecular pharmacology remains underdeveloped. This review proposes a novel meridian-based pharmacological framework that bridges classical TCM theory with contemporary precision oncology. Specifically, the direct tumor-suppressive effects of G. lucidum polysaccharides (GLPs) across organ-specific malignancies, including lung, liver, hematological, and genitourinary cancers, are systematically examined to explore potential associations between classical meridian tropism and tissue-specific anticancer activity. These organ-targeted effects are further linked to experimentally validated mechanisms, including cell-cycle arrest, apoptosis induction, DNA repair interference, autophagy modulation, inhibition of epithelial-mesenchymal transition, and sensitization to chemotherapy. Beyond their direct tumor-suppressive effects, GLPs also exhibit potent immunomodulatory activities that may enhance cancer immunotherapy. Their roles in regulating systemic immunity and remodeling the tumor microenvironment are highlighted through macrophage reprogramming, dendritic cell maturation, and cytotoxic T-cell activation, together with their potential synergistic interactions with immune checkpoint blockade therapies. By integrating direct tumor suppression with immune-mediated mechanisms within a meridian-based framework, this review provides a comprehensive perspective on the therapeutic potential of GLPs and offers insights to support their future clinical translation in oncology.",

Mir452 (microRNA 452) is a newly identified, highly sensitive biomarker for septic AKI, but the biological function of Mir452 was unknown. Here we report that Mir452 protects kidney tubular cells in septic AKI by repressing APAF1 (apoptotic peptidase activating factor 1) and associated caspase activation to preserve macroautophagy/autophagy. Using mouse and cell models of septic AKI induced by lipopolysaccharide (LPS), we found that inhibition of Mir452 exacerbated renal dysfunction, tubular apoptosis, and inflammatory responses, whereas Mir452 mimics significantly attenuated kidney injury. Mechanistically, Mir452 was shown to directly bind to the 3' untranslated region (3'UTR) of Apaf1 mRNA, repressing APAF1 expression and thereby inhibiting apoptosome-mediated CASP9 activation. This repression further alleviated caspase-mediated cleavage of autophagy-related proteins like BECN1 and ATG5, leading to the preservation of autophagic flux, which in turn limits inflammasome activation and inflammation. Notably, tubule-specific deletion of Apaf1 recapitulated the protective effects of Mir452, whereas forced Apaf1 expression aggravated injury, an effect reversed by CASP9 knockdown. Furthermore, Mir452 significantly promotes protective autophagy in septic AKI by suppressing the APAF1-CASP9 axis, as evidenced by upregulated ATG5 and BECN1 expression, enhanced LC3-II accumulation and autophagosome-lysosome fusion, along with reduced SQSTM1/p62 levels. Functional rescue experiments demonstrated that Mir452's anti-inflammatory effects depend entirely on activated autophagy, as overexpression fails when autophagy is inhibited. Together, the results unveil the Mir452-APAF1-CASP9-autophagy signaling axis that provides an intrinsic anti-inflammation and anti-apoptosis mechanism, suggesting new therapeutic targets for septic AKI.",

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

Quantitative immunohistochemical evaluation was performed using H-score analysis with Image Tool Software.ResultsThe study group exhibited significant increases in the expression of Beclin-1 (97.65\u2009\u00b1\u20092.54 vs. 25.53\u2009\u00b1\u20090.4), LC3A/B (97.88\u2009\u00b1\u20095.35 vs. 61.73\u2009\u00b1\u20095.08), ATG5 (100.73\u2009\u00b1\u20091.06 vs. 35.35\u2009\u00b1\u20090.3), p62 (84.18\u2009\u00b1\u20093.59 vs. 59.54\u2009\u00b1\u20092.29), and Bcl-2 (107.36\u2009\u00b1\u20091.60 vs. 53.56\u2009\u00b1\u20091.38) compared with the control group (p\u2009<\u20090.001 for all). Although Caspase-8 expression was also increased (65\u2009\u00b1\u20091.53 vs. 49\u2009\u00b1\u20090.2), the difference was not statistically significant (p\u2009=\u20090.270). These findings suggest altered regulation of autophagy-related pathways accompanied by suppression of apoptotic mechanisms, which may contribute to the persistence, fibrovascular proliferation, and progression of pterygium tissue.ConclusionThe progression of pterygium appears to be associated with dysregulation of autophagy-related pathways and inhibition of apoptotic mechanisms. These findings suggest that modulation of these cellular mechanisms may provide novel pharmacological therapeutic options, potentially reducing the need for surgical intervention.",

TAK-981 (subasumstat), a selective inhibitor of small ubiquitin-like modifier (SUMO)-activating enzymes, exhibits antitumor activity in several types of cancer; however, to the best of our knowledge, its therapeutic potential in Ut-LMS has not been explored. The current study evaluated the effects of TAK-981 on human Ut-LMS cells and revealed that SK-UT-1B cells exhibited markedly greater sensitivity to TAK-981 than SK-UT-1 cells. TAK-981 substantially reduced SK-UT-1B cell viability in a time- and concentration-dependent manner, whereas SK-UT-1 cells demonstrated a minimal response to TAK-981 at similar doses. Annexin V staining confirmed that TAK-981 induced the apoptosis of SK-UT-1B cells after 48 h, with apoptotic populations increasing proportionally with drug concentration. Furthermore, TAK-981 induced G0/G1 cell cycle arrest and markedly decreased Ki67 expression, indicating suppressed proliferative activity. TAK-981 also triggered substantial intracellular reactive oxygen species (ROS) accumulation and mitochondrial membrane depolarization, and antioxidant co-treatment demonstrated that apoptosis was partially ROS-dependent. Western blotting indicated robust inhibition of SUMO2/3 conjugation and activation of apoptotic markers, including cleaved caspase-3 and poly (ADP-ribose) polymerase, with the upregulation of p21 and p53. By contrast, autophagy markers, such as LC3B and p62, were unchanged, indicating that TAK-981 exerted its cytotoxic effects independently of the autophagic pathway. Collectively, these findings suggested that TAK-981 suppressed proliferation and induced apoptosis in SK-UT-1B Ut-LMS cells, accompanied by SUMOylation inhibition, ROS-associated mitochondrial dysfunction, apoptosis and G0/G1 cell-cycle arrest, and may represent a promising therapeutic candidate for further investigation in Ut-LMS.",

Evading cell death is a key characteristic of multiple cancers, including HCC. Many programmed cell death (PCD) processes, comprising apoptosis, autophagy, necroptosis, and ferroptosis, have been identified to affect tumor growth and recurrence of HCC. Ferroptosis is an emerging iron-dependent PCD mode characterized by lipid peroxidation and iron accumulation. It has emerged as a critical regulatory mechanism in HCC progression. Sirtuins (SIRTs), a class III histone deacetylases (HDACs) that require NAD+ as a cofactor, exhibit exclusive and poised functions in the pathophysiological processes of cancers by mediating ferroptosis. However, a summary of the mechanisms of SIRT-mediated ferroptosis in HCC development and associated therapeutic strategies is limited. This article provides an outline of recent developments in the role of SIRTs in HCC proliferation, metastasis, and the development of multidrug resistance. We highlight the roles and mechanisms of SIRTs in mediating ferroptosis in HCC, aiming to provide a comprehensive and novel perspective for developing diagnostic biomarkers and therapeutic strategies for HCC, thereby advancing the understanding of HCC pathogenesis and treatment.",

Here, we develop an antibacterial and conductive bioactive hydrogel based on flower-shaped MXene microspheres for treating methicillin-resistant Staphylococcus aureus (MRSA)-infected wounds. The hydrogel (PDM) is constructed by integrating \u03b5-poly-L-lysine-functionalized MXene microspheres into a dynamically crosslinked oxidized pullulan network via pH-responsive Schiff-base chemistry, conferring injectability, self-healing, tissue adhesion and environmental responsiveness. PDM effectively eliminates MRSA biofilms, scavenges reactive oxygen species and attenuates inflammatory responses while promoting adaptive autophagy. These combined properties enable modulation of the wound microenvironment, enhance macrophage polarization toward a regenerative phenotype and support cell proliferation, endothelial cell migration and angiogenesis. In addition, the conductive hydrogel promotes Schwann cell maturation and neurotrophic factor expression, facilitating reconstruction of the neurogenic microenvironment. In a murine full-thickness MRSA-infected wound model, a single application of PDM significantly accelerates wound closure, enhances cutaneous innervation and reduces fibrosis. This work presents a multifunctional MXene-based hydrogel platform for antibiotic-free infected wound healing.",

The current research examines the amino acid profile of SPI and PPI and evaluates their impact on bone health in\u00a0vivo and in silico. Female Sprague-Dawley rats were randomly assigned to four groups: T0 (Standard diet + without osteoporosis), T1 (Standard diet + osteoporosis), T2 (2\u2009g/kg bw of SPI+ 2\u2009g/kg bw of PPI), and T3 (3\u2009g/kg bw of SPI+ 3\u2009g/kg bw of PPI). Biochemical parameters and histopathology of bone (femur and tibia), liver, and kidney were evaluated. The amino acid profile demonstrated higher levels of glutamic and aspartic acids and a lower level of sulfur-containing amino acids. PPI exhibited higher content of arginine, lysine, and leucine than SPI. T3 significantly reduced the severity of disease compared with all other groups, as reflected in increased the osteocalcin levels (9.50\u2009\u00b1\u20091.85\u2009ng/mL), Ca (9.10\u2009\u00b1\u20091.06\u2009mg/dL), P (3.30\u2009\u00b1\u20090.08\u2009mg/dL), and lowering inflammatory levels of CRP (0.70\u2009\u00b1\u20090.04\u2009mg/L) and ESR (15.70\u2009\u00b1\u20091.58\u2009mm/h) in the respective treatment groups. Histological studies revealed no changes in bone, liver, and kidney tissues. Furthermore, molecular docking demonstrated potential interactions between gamma-carboxylase and ligands, such as genistein, \u03b2-sitosterol, glycitein, kaempferol, and quercetin, with binding affinities of -8.3, -9.0, -7.6, -7.6, and -8.1\u2009kcal/mol, respectively.

This study evaluated grape pomace extracts and their constituent flavonoids as potential efflux pump inhibitors (EPIs) to restore ciprofloxacin susceptibility. RP-HPLC analysis of the extracts identified quercetin, (+)-catechin, and (-)-epicatechin. The synergistic interaction between these agents and ciprofloxacin was assessed using the checkerboard method against three S. aureus strains: NCTC 8325-4 (norA wild type), K2378 (overexpressing norA), and K1902 (norA deletion). Additionally, ethidium bromide accumulation assays were conducted to quantify pump inhibition activity. All extracts and identified flavonoids exhibited synergism with ciprofloxacin, yielding Fractional Inhibitory Concentration Indices (FICI) ranging from 0.076 to 0.281. While crude extracts demonstrated nonspecific pump inhibition, the isolated flavonoid (-)-epicatechin showed inhibitory activity against the NorA effux pump. Conversely, (+)-catechin and quercetin displayed lower, concentration-dependent activity. These findings demonstrate that grape pomace flavonoids, particularly (-)-epicatechin, act as effective EPIs capable of efflux pumps mediated resistance, suggesting their potential utility as adjuvants in antimicrobial therapy.",

This review presents current evidence linking neurotropic viruses and host antiviral immunity to the onset and progression of neurodegeneration and neurocognitive dysfunction. We explore how viral infections, particularly by Herpesviruses, Severe Acute Respiratory Syndrome Coronavirus 2, and Human Immunodeficiency Virus, disrupt neural homeostasis through neuroinflammation, amyloidosis, tauopathy, and autophagy dysregulation in neurodegeneration including Alzheimer's disease (AD). Simultaneously, host antiviral mechanisms, including type I interferons and interferon regulatory factors, often amplify neuronal damage when dysregulated. By examining viral and immune interactions within the neurodegenerative diseases, this review aims to broaden our understanding of the viral-immune axis in the brain and inspire novel approaches to prevention and treatment.",

Bioinformatics analysis revealed significant enrichment of CCL2 in the TNF signaling pathway. ELISA and Western blot analyses confirmed marked upregulation of CCL2 in the serum of TBI patients as well as in the serum and brain tissues of TBI mouse models. Functional experiments demonstrated that CCL2 knockdown significantly alleviated neurological impairment and secondary brain injury in TBI mice. Mechanistically, CCL2 suppression enhanced neuronal autophagy, as evidenced by increased Beclin1 and LC3-II expression and modulation of autophagy flux markers (p62 and LAMP2), while simultaneously attenuating neuronal apoptosis through regulation of apoptosis-related proteins, including Bcl-2, Bax, and cleaved caspase-3. Rescue experiments further showed that TNFR1 overexpression abolished the protective effects of CCL2 knockdown and restored activation of the TNF signaling pathway, accompanied by elevated MCP-1, TNFR1, and phosphorylated p65 levels. Collectively, these findings demonstrate that CCL2 promotes TBI progression by activating the TNF signaling pathway, thereby suppressing autophagy and enhancing apoptosis. Targeting the CCL2-TNFR1 axis may represent a promising therapeutic strategy for secondary brain injury following TBI.

"42404999": "ID: 42404999\nTitle: SPG7-Mediated Regulation of mPTP and Mitochondrial Flickering in COPD: A Bioinformatics-Based Prediction of Mechanistic Framework.\nAbstract: During the staged progression of chronic obstructive pulmonary disease (COPD), mitophagy homeostasis is disrupted and exhibits a typical dual role. Mitophagy is tightly regulated by ion channel-controlled mitochondrial membrane potential (\u0394\u03a8m) and may associate with mitochondrial permeability transition pore (mPTP) dynamics. However, this regulatory mechanism remains largely unknown, and the stage-specific requirements of mitophagy in COPD progression have yet to be established. This study proposed a novel theoretical framework from prior literature. Using public databases, we linked mPTP-related genes to COPD state transitions via differential analysis and Mendelian randomization (MR). Key biomarkers were validated through gene enrichment, functional annotation, immune infiltration, and single-cell RNA sequencing (scRNA-seq) to assess biological significance. Finally, molecular docking confirmed their potential roles. We preliminarily aligned the \"mitochondria-cell survival architecture\" hypothesis with COPD progression. Compared with stable COPD (STCOPD), acute exacerbation of COPD (AECOPD) showed massive type II alveolar epithelial (AT2) cell death, hyperinflammation, increased energy demand, and impaired intercellular communication, consistent with activated ubiquitin-proteasome system (UPS), mitochondrial gene expression, macroautophagy initiation, and vesicle trafficking. Six biomarkers (including SPG7) were associated with AECOPD (AUC=0.705, 95% CI 0.554-0.705). SPG7 was positively correlated with AECOPD (OR=1.126, 95% CI 1.008-1.257), while the other five showed negative correlations. These markers were enriched in ion channel and G protein-coupled receptors (GPCRs) pathways. SPG7 expression paralleled energy demand and strongly interacted with AFG3L2 and PPIF, implicating it in mPTP regulation. This study preliminarily supports the mitochondria-cell survival hypothesis. Bioinformatic analysis suggests that mPTP-triggered mitochondrial flickering maintains mitochondrial quality control. Furthermore, transient mPTP opening via SPG7-mediated CypD activation may constitute an independent protective pathway, potentially involving unique SPG7-CypD modifications. However, non-significant colocalization limits study robustness, necessitating rigorous experimental validation of these predictions.",

Structural characterization of the resulting compounds (3 and 4a-4m) was confirmed by NMR and HR-MS analyses. Among the synthesized derivatives, compounds 3 and 4k exhibited the most potent and selective cytotoxicity. Compound 3 demonstrated IC50 values of 2.97 \u00b5M (SKBR3), 4.4 \u00b5M (DU145), and 20.5 \u00b5M (HEK-293), while compound 4k showed strong activity against HepG2 (2.27 \u00b5M) and DU145 (5.01 \u00b5M). Genotoxic assessment revealed that 4k maintained a favourable safety profile, with chromosomal aberration and micronucleus frequencies remaining low or only mildly elevated at higher doses, and a moderate, dose-dependent decrease in mitotic index. Mechanistic studies indicated G0/G1 cell cycle arrest in CHO-K1, DU145, and HepG2 cells, along with significant apoptosis induction in HepG2 (Sub-G1: 13.9%). Although its antioxidant potential was moderate relative to rutin, 4k exhibited dose-dependent free radical scavenging. Antidiabetic screening identified compounds 1, 3, 4c, and 4m as effective \u03b1-glucosidase inhibitors (52.6-58.5%; IC50 = 4.27-4.75 \u00b5g mL-1), comparable to acarbose. Antimicrobial evaluation showed broad-spectrum activity for compound 1, and compound 4k displayed membrane-stabilizing effects similar to quercetin. In conclusion, these multifunctional vanillin-piperidone hybrids especially compound 4k demonstrate significant anticancer, antidiabetic, and antimicrobial potential, further strengthened by their confirmed non-genotoxic profile.",

Despite advances in surgery, chemotherapy, and targeted therapies, many CRC patients experience limited efficacy, toxicity, or drug resistance. Thus, complementary therapeutic strategies with an improved safety profile are needed. Plant-derived polyphenols emerge as promising candidates for CRC treatment. This review compiles in vitro, in vivo, and clinical evidence on the anticancer activity of polyphenols in CRC. Polyphenols, such as curcumin, resveratrol, quercetin, and flavonoids, are analyzed, with emphasis on molecular mechanisms and chemopreventive potential. In vitro studies consistently demonstrate that these compounds exert anticancer effects by modulating multiple pathways, including PI3K/AKT/mTOR, Wnt/\u03b2-catenin, STAT3, and MAPK/ERK, promoting apoptosis and regulating oxidative stress and inflammation. In vivo studies indicate that curcumin, resveratrol, quercetin, epigallocatechin gallate (EGCG), genistein, luteolin, and fisetin significantly reduce tumor volume, polyp formation, and aberrant crypt foci (ACF). Curcumin has been extensively evaluated in trials, with some studies demonstrating reductions in ACF and improvements in inflammatory markers and quality of life, while others have demonstrated no significant clinical benefit. Preclinical evidence supports the chemopreventive role of polyphenols. Preliminary clinical trials also suggest therapeutic potential for CRC prevention and treatment; however, large-scale, well-controlled clinical trials are required to confirm their safety and efficacy. Plant-derived polyphenols represent promising complementary strategies for CRC prevention and therapy. Future research should prioritize compounds with strong preclinical evidence, standardized formulations, optimized delivery strategies, and rigorously designed randomized trials to facilitate integration into clinical oncology practice.",

NLRP3 is a key player in controlling Interleukin-1\u03b2 (IL-1\u03b2) and Interleukin-18 (IL-18) maturation and pyroptosis via its NOD-like receptor pyrin domain-containing 3 (NLRP3) inflammasome. This review will assess the mechanistic and therapeutic opportunity of resveratrol in restraining the NLRP3 inflammasome activation. A search of experimental and preclinical studies examining the impact of resveratrol on oxidative stress, inflammatory signaling, mitochondrial activity, and inflammasome activation in various disease models was performed. Resveratrol reduces oxidative stress by regulating reactive oxygen species-mediated nuclear factor erythroid 2-related factor 2 signaling and suppressing toll-like receptor 4 (TLR4) /nuclear factor kappa B signaling (NF-\u03baB). It maintains mitochondrial integrity by activating sirtuin 1 and AMP-activated protein kinase signalling. In models of acute lung injury, bronchitis, diabetic nephropathy, and neurodegeneration, resveratrol can suppress the expression of NLRP3, caspase-1, and IL-1\u03b2, promote autophagy, and prevent dopaminergic neurons through the PINK1/Parkin/NLRP3 pathway. Additionally, it enhances intestinal barrier integrity in dextran sulfate sodium-induced colitis and suppresses inflammasome-mediated inflammation. These results suggest that resveratrol regulates the priming and activation stages of NLRP3 inflammasome signaling by inhibiting oxidative stress, mitochondrial dysfunction, and inflammatory cascades based on redox signaling. Nanoparticle preparations and structural analogs, such as pterostilbene, improve stability, bioavailability, and specific delivery. Resveratrol is a potential natural therapeutic agent for managing NLRP3 inflammasomemediated inflammation, and its efficacy is enhanced when administered in optimal formulations and combined with conventional anti-inflammatory agents.",

Nanotechnology-based drug delivery provides modular approaches that improve intratumoral accumulation, safeguard payloads, and facilitate controlled release, all while reducing off-target damage. This review compiles the latest findings in the field of oral cancer targeting magnetic nanomaterials, cyclodextrins, quantum dots, dendrimers, and metallic/inorganic platforms (metal-organic frameworks). Mechanistic innovations encompass both passive and active targeting strategies (e.g., EGFR, folate, CD44), stimuliresponsive mechanisms (pH, enzyme), and precision systems guided by salivary biomarkers (e.g., IL-8, CYFRA 21-1), ultimately leading to enhanced therapeutic indices and real-time theranostic monitoring. Innovative approaches use AI-driven design, biosensor-facilitated early detection, and Nanovaccine/immunenanomedicine techniques to personalise treatment in the multifaceted oral tumour microenvironment. Translational challenges remain, including heterogeneous EPR effects, nanotoxicology (encompassing autophagy and ROS pathways), manufacturing scale-up, and regulatory standardisation. These issues require the development of robust pharmacology-toxicity frameworks and biomarker-driven clinical trials. Nanocarriers of the future may revolutionise OSCC treatment by bringing together materials science, tumour biology, and genetic and salivary signals that are unique to each patient.

This study evaluated the therapeutic efficacy of zingerone(4-(4-hydroxy-3-methoxyphenyl)-2-butanone) in a letrozole-induced hyperandrogenised PCOS-like mouse model. Zingerone administration, particularly at 25 and 50\u2005mg/kg, significantly improved ovarian morphology by enhancing follicular development and corpus luteum formation. This was accompanied by increased granulosa cell proliferation (PCNA) and attenuation of apoptosis, evidenced by up-regulation of BCL2 and reduced TUNEL staining. Zingerone reprogrammed ovarian steroidogenesis by reducing circulating testosterone, down-regulating androgen receptor expression, suppressing StAR, and up-regulating aromatase, thereby promoting a shift toward estrogen biosynthesis. Autophagy analysis indicated restoration of autophagic flux, reflected by decreased p62 levels and modulation of Beclin1 and LC3B expression. These coordinated molecular and cellular changes resulted in functional recovery, with significant improvement in fertility and litter size at higher doses (25 and 50\u2005mg/kg). Collectively, zingerone exerts dose-dependent, multi-target effects to restore endocrine, cellular, and autophagic homeostasis, thereby ameliorating ovarian dysfunction in PCOS.",

Here we characterize the plant RAB GTPase RABC1 as a regulator of ER-phagy during ER stress. Our results demonstrate that rabc1 mutants are hypersensitive to heat shock and ER stress inducers dithiothreitol and tunicamycin. RABC1 localizes primarily to the ER and Golgi with partial trans-Golgi network (TGN) association. Upon ER stress, RABC1 is recruited to autophagosomes and subsequently delivered into the vacuole. Autophagic turnover of the ER chaperone Calnexin (CNX1)-GFP is impaired in the rabc1 mutant after DTT and TM treatments. Additionally, RABC1 interacts with the exocyst subunit SEC5A in planta, and this interaction is required for SEC5A recruitment to autophagosomes, promoting autophagosome formation. Double-mutant analysis indicates an additive genetic interaction between RABC1 and SEC5A in ER stress sensitivity. Taken together, our results suggest that RABC1 coordinates with SEC5A to promote autophagosome formation and ER-phagy during ER stress, revealing a novel mechanism by which a plant RAB GTPase regulate ER-phagy.",

However, its specific role in breast cancer remains poorly understood. RPA3 expression and its prognostic relevance in breast cancer were assessed based on the public databases. To further confirm the biological function of RPA3, we knocked down RPA3 in the breast cancer cell line Michigan Cancer Foundation-7 (MCF-7) and then conducted Cell Counting Kit-8, colony formation, Western blot, immunofluorescence, and transmission electron microscopy. In vivo effects of RPA3 were tested in a xenograft model. We found that high expression of RPA3 in breast cancer predicted adverse patient outcomes. RPA3 was mainly involved in multiple oncogenic signaling pathways, including the transforming growth factor-\u03b2 (TGF-\u03b2) pathway. RPA3 knockdown effectively suppressed cancer cell proliferation in vitro and in\u00a0vivo. Mechanistically, RPA3 knockdown decreased TGF-\u03b21 promoter activity and reduced TGF-\u03b21 expression at mRNA and protein levels, accompanied by decreased p-Smad2/3 levels. RPA3 knockdown also significantly blocked autophagy, as evidenced by decreased microtubule-associated protein 1 light chain 3 (LC3)-II/LC3-I ratio, increased sequestosome 1 (p62) level, and reduced LC3 puncta. Notably, pharmacological activation of the TGF-\u03b2 pathway partially reversed autophagy alterations induced by RPA3 knockdown. These data support the possibility of RPA3 as a therapeutic target for breast cancer.",

However, the epidemiological characteristics of CKD in women and its epidemiological association with metabolic disorders and cardiovascular diseases (CVDs) remain unclear. Based on data from the Global Burden of Disease study 2021, this research used Joinpoint regression analysis to identify the global trends of CKD in women. A comprehensive assessment of CKD burden in women was conducted across multiple dimensions, such as age stratification, five CKD subtypes, sociodemographic index, decomposition analysis, risk factors, and CVD attributable to kidney function impairment. In 2021, the global number of women with CKD reached 359 million, an increase of 90.65% compared to 1990, with the absolute number of diabetic kidney disease cases nearly doubling. Nearly two-thirds of patients were postmenopausal women, and their age-standardized mortality rate and age-standardized disability-adjusted life-years (DALYs) rate had significantly increased to 64.03 and 1493.31 per 100,000, respectively. The age-standardized prevalence rate among women of reproductive age demonstrated a continuous upward trend (average annual percentage change, 0.13%). Regionally, the age-standardized mortality rate and age-standardized DALY rate of women with CKD were highest in the regions with low and low-middle sociodemographic index (SDI), while the age-standardized prevalence rate was highest in low-middle SDI regions. Metabolic risk factors constituted the main attributable risk factors for CKD in women, with risks owing to high fasting glucose and high body mass index rapidly increasing among women of reproductive age (by 40.66% and 112.17%, respectively). CVD attributable to kidney function impairment accounted for 18.19 million DALYs, representing 46.70% of the total disease burden, with ischemic heart disease being the main contributor. Population growth (58.63%) and aging (26.64%) were the main drivers of the increasing burden of CKD in women.

A clinically important expression of these off-target effects is hematologic toxicity, including immune-mediated cytopenias and direct bone marrow suppression. This narrative review examines whether the same biology that injures normal hematopoietic cells can, in selected contexts, reveal therapeutically exploitable vulnerabilities in leukemia. We synthesize molecular, clinical, and preclinical evidence and organize it into an integrative framework linking mitochondrial translation inhibition, mitonuclear imbalance, oxidative phosphorylation failure, reactive oxygen species generation, DNA/topoisomerase stress, autophagy and lysosomal-flux blockade, and apoptosis modulation with both hematotoxicity and antileukemic activity. The strongest preclinical evidence supports selected tetracyclines, macrolides, and oxazolidinones, whereas evidence for beta-lactams, glycopeptides, polymyxins, rifamycins, fluoroquinolones, and folate-pathway agents remains more limited or largely hypothesis-generating. Importantly, antibiotic-induced cytopenia should not be interpreted as proof of leukemia selectivity: immune-mediated toxicity, supratherapeutic in vitro exposure, normal progenitor injury, pharmacokinetic constraints, microbiome effects, and resistance mechanisms all narrow the translational window. Overall, antibiotic hematotoxicity is best viewed as a biologically informative signal that can guide mechanism-based repurposing and combination strategies, but clinical development requires rigorous pharmacokinetic/pharmacodynamic validation, normal hematopoietic comparators, and biomarker-driven patient selection.",

It includes dysgenesis of the corpus callosum, cataracts, hypopigmentation, cardiomyopathy, and immuno-deficiency. Here we report a case of a 9-year-old boy of Roma ethnicity with a milder form of Vici syndrome and a novel variant in the EPG5 gene. Methods. DNA and RNA were extracted from the whole blood. Whole exome sequencing was performed and analysed with an in-house bioinformatics pipeline. A mini-gene assay was performed for EPG5 exon 23 with or without the tested variant. Results. The patient was born prematurely and presented with hypotonia, severe hypotrophy and growth retardation, developmental delay, congenital heart defects, mild brain atrophy, and a thin corpus callosum. Whole exome analysis identified a novel variant c.4205G>A, p.(Arg1402Lys) in the EPG5 gene, suggesting the diagnosis of Vici syndrome. Further examination of symptoms commonly associated with Vici syndrome confirmed hypopigmented skin areas and immunodeficiency. No seizures, cataracts, or cardiomyopathy were observed. As the variant is located at the last base of exon 23, we sequenced the patient's EPG5 mRNA and detected aberrant transcripts in addition to correctly spliced ones. The mini-gene assay confirmed decreased inclusion of the mutated exon compared with the wild-type (40% vs. 72%, respectively). Conclusion. Novel variant EPG5:c.4205G>A, p.(Arg1402Lys) causes aberrant splicing only in a small proportion of transcripts; therefore, the milder presentation of Vici syndrome in our patient is probably due to the residual presence of EPG5 protein.",

This study aimed to elucidate the protective effect of agmatine (AGM) on sepsis-induced intestinal injury and its mitochondrial-targeted antiapoptotic mechanism in intestinal epithelial cells (IECs). We verified the transport and subcellular localization of AGM in IECs via fluorescence assays and established in vitro and in vivo IEC apoptosis models. Functional evaluations using cell viability assays, laser confocal imaging, flow cytometry, transmission electron microscopy, and multiomics techniques were performed. AGM attenuated sepsis-induced intestinal injury, as evidenced by its ability to lower the serum levels of intestinal damage markers in septic mice, attenuate inflammatory factor production and pathological damage in the intestine, and reduce IEC apoptosis. AGM entered IECs via the polyamine transport system (PTS), but not the NMDA receptor, and inhibited IEC apoptosis induced by TNF\u03b1/CHX or TNF\u03b1/ActD. Notably, AGM exerted its antiapoptotic effect by targeting the mitochondrial imidazoline I2 receptor (I2R). Mechanistically, AGM induced mitophagy by decreasing the mitochondrial membrane potential without altering mitochondrial number or function, as ROS production, calcium ion influx, ATP generation, and oxygen consumption were unchanged. AGM also increased autophagic flux, as confirmed upon treatment with various autophagy inhibitors. AGM alleviates sepsis-induced intestinal injury via the PTS-I2R axis by promoting mitophagy and autophagic flux to inhibit IEC apoptosis, laying a foundation for the use of AGM as a potential nutritional supplement or therapeutic agent for sepsis-induced intestinal injury.",

PANoptosis, in contrast to single cell death mechanisms, is a web of events coordinating neuronal death, glial cell changes, and inflammatory signals, being implicated in the initiation and progression of neurodegenerative and neuroinflammatory diseases. This review compiles current knowledge of the molecular pathways of PANoptotic signaling, its interaction with autophagy and immune pathways, and the in vivo models utilized for its pathogenic role in the central nervous system. We also tackle translational hurdles such as biomarker identification, therapeutic safety, disease, stage precision, and patient heterogeneity, which all point to the necessity of highly accurate interventions. Moreover, novel techniques combining systems biology, AI-based target identification, and personalized neuroimmunomodulation may effectively harness PANoptosis regulation to be both controlled and disease-specific. Through bridging the gap between the mechanistic insights and the translational perspectives, this review points out that PANoptosis provides a comprehensive basis for neuroimmune-associated pathology and represents a viable target for novel therapeutic approaches to counteract both chronic neuroinflammation and neurodegeneration.",
"42406202": "ID: 42406202\nTitle: Solvent-driven modulation of phenolic composition and biofunctional activities of three Mentha aquatica formulations: integrated in vitro and in silico insights.\nAbstract: The goal of this work was to examine the effect of different solvents (Water, EtOH 70%, and acetone) on the phenolic composition, antioxidant, and antibacterial capacity of Moroccan Mentha aquatica L. leaf extract. To this end, HPLC-ESI-FULL-MS was used to characterize the extracts, while the Folin-Ciocalteu and aluminum trichloride techniques were used to evaluate the total phenolic and flavonoid contents. To assess the antibacterial capacity, the microdilution technique was performed to calculate the minimal inhibition concentration (MIC), and minimal bactericidal concentration (MBC). Phytochemical profiling revealed that the extracts were rich in bioactive constituents, particularly ferulic acid derivative, caffeoyl-protocatechuic acid derivative, quercetin, and diosmetin 7-O-beta-D-glucuronide. The hydroethanolic extract contained the highest levels of total phenolic (62.2\u2009\u00b1\u20091.2\u00a0mg GAE/g DW) and flavonoid (29.15\u2009\u00b1\u20090.09\u00a0mg QE/g DW) contents, exceeding those of the acetonic extract (22.2\u2009\u00b1\u20090.6 and 10.17\u2009\u00b1\u20090.07\u00a0mg GAE/g DW, respectively) and the water extract (22.4\u2009\u00b1\u20090.6 and 10.9\u2009\u00b1\u20090.6\u00a0mg QE/g DW, respectively). This extract also showed the strongest antioxidant effect, recording an IC50 of 0.060\u2009\u00b1\u20090.001\u00a0mg/mL in the DPPH assay, and an EC50 of 80\u00a0\u00b5g/mL in the RP test. In addition, it shows a great total antioxidant capacity, reaching 75.1\u2009\u00b1\u20092.0\u00a0mg EAA/g DW when compared to water and acetonic extracts (28.5\u2009\u00b1\u20091.4 and 21.1\u2009\u00b1\u20090.1\u00a0mg EAA/g DW, respectively). The antibacterial potential ranges from 0.78\u2009\u00b1\u20090.05\u00a0mg/mL to 12.6\u00a0mg/mL. In-silico prediction highlighted diosmetin 7-O-beta-D-glucuronide, quercetin, and equisetumpyrone as the key contributors to antioxidant capacity, while quercetin, 2,3,8-Tri-O-methylellagic acid, and diosmetin 7-O-beta-D-glucuronide were involved in antibacterial activity.",
"42406229": "ID: 42406229\nTitle: Safe and effective control of Mycoplasma gallisepticum: pharmacokinetic and residue profiling of doxycycline combined with quercetin nanomicelles.\nAbstract: Although doxycycline is widely used to combat Mycoplasma gallisepticum (MG), misuse promotes antimicrobial resistance. Quercetin exhibits antibacterial potential; however, its application is limited by poor bioavailability, and its nanomicelle-based delivery with doxycycline remains uninvestigated. This study evaluated the efficacy, pharmacokinetics, and residue depletion of doxycycline combined with quercetin and quercetin nanomicelles against MG infection in broilers using a validated green high-performance liquid chromatography approach. One-day-old chicks were divided into seven groups: negative and positive controls, and treatment groups that received doxycycline, quercetin, or quercetin nanomicelles orally at doses of 25, 50, and 50\u00a0mg/kg body weight, respectively, either alone or in combination, for five days post-challenge. Pharmacokinetic parameters and residue depletion were investigated in treated groups at multiple time points. Tracheal and lung samples were collected at two intervals for MG enumeration and virulence gene expression. Quercetin and its nanomicelles displayed minimum inhibitory concentrations (MICs) of 0.47 and 0.02\u00a0\u00b5g/mL, respectively; their combinations with doxycycline had fractional inhibitory concentration indices of 6 and 0.375, respectively. Nanomicelles were characterized by size, polydispersity index, zeta potential, and encapsulation efficiency values of 345.66\u00a0nm, 0.14, 19.1 mV, and 96.1%, respectively, with no cytotoxicity up to 8\u00d7 MIC. In vivo, the greatest reductions in MG counts and in mgc2, adrA, and crmA expression were observed in nanomicelle-treated groups. Co-administration of doxycycline with nanomicellar quercetin improved systemic exposure, prolonged serum persistence above the MIC, and supported extended dosing intervals while maintaining favorable tissue depletion profiles. Conversely, conventional quercetin negatively influenced doxycycline pharmacokinetics, causing therapeutic failure.",

REJENERA\u00a9, a newly developed nutraceutical formula against OA, contains primarily olive leaf bioflavonoids ( ZeyEX\u00a9, quercetin and luteolin), S-allylcysteine, palmitoylethanolamide, L-proline, hyaluronic acid and boron. This study focuses on the efficacy of REJENERA in treating knee OA and aims to compare it with ZeyEX, NPROC\u00a9 (a product obtained by combining collagen-rich eggshell membrane with olive leaf extract), and IBUPROFEN in a rat OA model. OA was established by intra-articular injection of monosodium iodoacetate (MIA; 3\u00a0\u00a0mg) into the right knee joints. Rats were either left untreated or treated orally for 12\u00a0weeks with REJENERA, ZeyEX, NPROC (300\u00a0mg/kg/day) or IBUPROFEN (3\u00a0mg/kg/day). MIA injection produced joint degeneration including increased fissure-index, osteophyte-score, and OARSI-score, joint swelling, synovial inflammation, proteoglycan loss, and decreased cartilage thickness. These histopathological abnormalities were partially but significantly alleviated by REJENERA and other treatments. Only ZeyEX significantly inhibited the OA-induced increase in IL-1\u03b2, IL-6, IL-10 and LPO in serum, and IL-6, TNF-\u03b1, and IFN-\u03b3 in synovial fluid. While increases in MMP-3 and MMP-9 were reduced with all treatments, MMP-13 was inhibited only by REJENERA. ZeyEX increased IL-2, NPROC increased IL-6, and IBUPROFEN inhibited IL-10. All treatments improved TIMP-1 levels; however, TXNIP was more significantly inhibited by ZeyEX, and NLRP3 by REJENERA. REJENERA's anti-OA effects are accompanied by an increase in cartilage anabolic factors (Ki-67, type-II collagen, BMP-7) and inhibition of apoptosis. REJENERA offers a promising multi-targeted therapeutic approach to treating OA by blocking the iNOS-TXNIP-NLRP3\u00a0signaling axis, and reducing oxidative stress.",
"42406931": "ID: 42406931\nTitle: Hepatoprotective Effects of Baccaurea motleyana Fruit Extract Against CCl4-Induced Liver Injury in Rats: In Vivo Evaluation and GC-MS Phytochemical Profiling.\nAbstract: Over 25% of people worldwide have liver illnesses, which kill nearly 2 million. This study assessed the hepatoprotective potential of Baccaurea motleyana fruit acetone extract (BMF-AE) against CCl4-induced liver injury. GC-MS phytochemical profiling identified nine metabolites, with linoleic acid ethyl ester, quercetin, and gallic acid as predominant bioactives known for hepatoprotective activity. The antioxidant activity of BMF-AE was significant in DPPH and ABTS assays, with IC50 values of 112.55 and 127\u00a0\u00b5g/mL, respectively. In vivo hepatoprotective efficacy was assessed in five groups (n = 5) that received oral BMF-AE (200 or 400\u00a0mg/kg) for 14 days. Positive control was 100\u00a0mg/kg silymarin. The CCl4-induced increase in serum ALT, AST, ALP, and bilirubin was dramatically reduced, while BMF-AE restored albumin levels (p < 0.05). Treatment reduced hepatic TBARS and restored glutathione and catalase activity, reducing oxidative stress. Histopathological investigation demonstrated maintained liver architecture in treated rats. Molecular docking analysis revealed that quercetin and linoleic acid ethyl ester bind strongly to targets of oxidative stress and inflammation, including xanthine oxidoreductase, interleukin-6, tumor necrosis factor-\u03b1, and PARP-1, suggesting potential hepatoprotective effects. BMF-AE may be a promising natural therapy for oxidative stress-mediated liver injury, according to this study, due to its antioxidant phytoconstituents.",

Despite some progress in modern medicine for the treatment of CHF, challenges remain, including insufficient therapeutic efficacy and significant side effects. In this context, traditional Chinese medicine (TCM), characterized by its multi-component, multi-target, and holistic regulatory properties, demonstrates potential advantages in the prevention and treatment of CHF. This paper summarizes the research progress of active ingredients from Chinese medicinal herbs, single herbs, and traditional Chinese herbal formulations in addressing key pathological mechanisms related to CHF. These mechanisms include inflammation and oxidative stress, mitochondrial quality and energy metabolism disorders, myocardial remodeling, ferroptosis, and autophagy abnormalities. A multi-target framework is constructed by linking active ingredients from Chinese medicinal herbs, the signaling pathways they regulate, and the corresponding pathological mechanisms involved in CHF. Further integrating the classification background of HFrEF, HFmrEF, and HFpEF, this paper analyzes the potential differential focal roles of TCM-related mechanisms across different heart failure subtypes and pathological processes, and discusses existing problems in current research in the aspects of evidence hierarchy, druggability of active components, quality control, and clinical translation, as well as other related fields. This paper aims to provide a reference for subsequent research on TCM-based prevention and treatment of CHF.",
"42407132": "ID: 42407132\nTitle: Complexation between mannoprotein-grape polysaccharide nanoparticles and quercetin was associated with color restoration: A mechanistic exploration in model red wine solutions.\nAbstract: Different mannoprotein (MP)-grape polysaccharide (GP) nanoparticles (MGPN) were fabricated and complexed with quercetin to analyze their abilities and mechanisms in modulating the color of model red wine solutions (MRWS). MRWS showed yellowish hue recession of up to 92.52%, which should be associated with the complexation ability of MGPN towards quercetin. MGPN of 75% GP proportions with Ca2+ or K+ contained 2.2- to 10-fold or 1.64- to 4.48-fold higher quercetin than other MGPN counterparts, which conferred MRWS the highest and second highest yellowish hue recession rates, respectively. The surface hydrophobicity, Zeta-potential, and FTIR data together indicate that Ca2+ and K+ might strengthen the hydrogen bonds/electrostatic interactions and hydrophobic interactions between MGPN and quercetin, respectively. Molecular dynamic simulation suggests that increased GP proportions in MGPN with Ca2+ benefited quercetin complexation by improving 26.3%-40.48% structural stabilities and increasing 13.36%-40.1% complexed quercetin molecules in the MGPN-quercetin complexes, rather than enhancing the interaction energies.",
"42407178": "ID: 42407178\nTitle: Macrophage autophagy in allergic diseases: Regulatory mechanisms, immune crosstalk, and therapeutic implications.\nAbstract: Macrophages are pivotal effector cells within the innate immune system, playing a central role in inflammation regulation, tissue homeostasis, and immune defense. Recent studies have demonstrated that macrophage autophagy-a highly conserved process essential for cellular homeostasis-plays a critical role in dynamically balancing immune responses by selectively eliminating damaged organelles, pathogens, and protein aggregates. Macrophage autophagy is finely regulated by various signaling pathways, such as mTOR and NF-\u03baB, and its dysfunction is closely associated with the onset and progression of allergic diseases. This review systematically synthesizes the molecular mechanisms governing macrophage autophagy and its dual role in allergic diseases, including allergic rhinitis, asthma, and atopic dermatitis. It highlights the functions of key signaling pathways (e.g., mTOR, NF-\u03baB) and regulatory factors (e.g., p62, Beclin-1, LC3) and explores the crosstalk between macrophage autophagy, immunometabolism, and cellular polarization. Explores the crosstalk between macrophage autophagy, immunometabolism, and cellular polarization, and further elaborates the reciprocal regulatory network of autophagy and metabolic reprogramming within allergic inflammatory microenvironment. Furthermore, the review summarizes potential therapeutic strategies targeting macrophage autophagy, such as budesonide/simvastatin combination therapy and rapamycin derivatives, along with their clinical translation prospects, with the aim of providing a theoretical foundation for developing novel, autophagy-targeted precision therapies for allergic diseases.",
"42407185": "ID: 42407185\nTitle: Deep learning of multiplexed mitochondrial morphology identified natural compound combinations against skin photoaging.\nAbstract: Skin photoaging is primarily driven by mitochondrial dysfunction. Although natural products have demonstrated protective effects against Ultraviolet (UV)-induced damage, efficient screening strategies for mitochondrial-targeting compounds remain limited. Artificial Intelligence (AI)-assisted high-content screening strategy offers a valuable approach to identify bioactive candidates and elucidate their mechanisms. This study aimed to employe an AI-assisted high-content screening strategy to identify mitochondrial-enhancing natural compounds that prevent skin photoaging and to evaluate their protective efficacy. This study employed an AI-assisted high-content screening strategy to identify mitochondria-targeting compounds that mitigate photodamage. UVB-induced models were established in cells, zebrafish, and mice with UVB lamp irradiation. Mitochondrial morphology and function were quantified using JC-1, TMRM, and MitoTracker probes. Cell viability, SA-\u03b2-gal activity, and protein expression were assessed by CCK-8 assay, SA-\u03b2-gal staining, and Western blotting, respectively. Using AI-assisted high-content screening, we identified quercetin, spermidine, adenosine, Vitamin K2, and Mirabilis jalapa extract as mitochondrial protective compounds. Two optimized combinations, CC-1 and CC-2, restored ATP production, TCA cycle flux, and mitochondrial morphology in UVB-exposed human dermal fibroblasts (HDFs), reduced SA-\u03b2-gal activity, and upregulated COLLAGEN I, LAMIN B1, and SIRT3 expression. Both combinations alleviated the UVB-induced senescence phenotype by upregulating SIRT3. In a UVB-exposed zebrafish tail amputation model, CC-2 markedly promoted fin regeneration. These findings were validated in UVB-irradiated mice, where CC-2 demonstrated superior efficacy. Using AI-assisted high-content screening, we formulated two optimized combinations that alleviate UVB-induced skin photoaging, with CC-2 exhibiting superior efficacy, highlighting its potential as cosmetic additive.",

Natural products, with their diverse chemical structures and pharmacological activities, provide a promising avenue for multi-target therapies. This review analyzes key natural product classes, such as phenolic compounds, terpenoids, flavonoids, and alkaloids. It aims to elucidate their mechanisms by modulating critical oncogenic pathways to overcome drug resistance, paving the way for rational therapeutic design strategies. A comprehensive literature review was conducted by systematically searching Web of Science, PubMed, and Google Scholar. Search queries combined \"acute lymphoblastic leukemia\" with various natural product classes, focusing on publications from 2000 to 2025. The analysis synthesized data on molecular mechanisms, pharmacokinetics, safety, and synergistic strategies for combination therapy. The database search yielded 303,464 hits, with 13,839 hits from Web of Science, 14,625 hits from PubMed, and 275,000 hits from Google Scholar. After removal of duplicates, commentary articles, clearly ineligible literature, and records not within the predefined topic range were removed, 280 records were screened. 73 publications were assessed for eligibility, and 53 studies were included in the final synthesis. The studies considered in this review largely focused on chemically characterized natural products and derivatives comprising phenolic compounds, terpenoids, flavonoids, alkaloids, and artemisinin-related compounds. Most evidence was collected from preclinical ALL models and involved modulation of apoptosis, oxidative stress, cell-cycle arrest, autophagy, ferroptosis, and ALL-related signaling pathways. In conclusion, these natural products showed multi-target and pathway-intersecting activities that could improve conventional anti-leukemic treatment and overcome chemoresistance, although clinical translation remains limited by insufficient in vivo validation, insufficient PK/PD characterization, poor bioavailability, and incomplete safety evaluation. Natural products offer a valuable resource for developing novel anti-ALL therapeutics. Their multi-target capability fosters synergistic combinations to combat resistance, highlighting the need for advanced technologies and precision medicine approaches in ALL treatment."
