Cerebrospinal fluid amyloid beta 42, total tau, and phosphorylated tau 181 are well accepted markers of Alzheimer's disease. These biomarkers better reflect disease pathogenesis compared to clinical diagnosis. Here, we perform a genome wide association study meta-analysis including 18,948 individuals of European ancestry and identify 12 genome-wide significant loci across all three biomarkers, eight of them novel. We replicate the association of biomarkers with APOE, CR1, GMNC/CCDC50 and C16orf95/MAP1LC3B. Novel loci include BIN1 for amyloid beta and GNA12, MS4A6A, SLCO1A2 with both total tau and phosphorylated tau 181, as well as additional loci on chr. 8, near ANGPT1 and chr. 9 near SMARCA2. We also demonstrate that these variants have significant association with Alzheimer's disease risk, disease progression and/or brain amyloidosis. The associated genes are implicated in lipid metabolism independent of APOE, coupled with autophagy and brain volume regulation driven by total tau and phosphorylated tau 181 dysregulation. Show less

Apolipoprotein E (APOE) alleles are well-established genetic risk factors for Alzheimer's disease (AD), but their effects on AD biomarkers (amyloid beta [AΞ²]42/40, phosphorylated tau [p-tau]181, neurofilament light chain [NfL], and glial fibrillary acidic protein [GFAP]) may vary across populations due to ancestry-, age-, and sex-related differences. We hypothesized that these effects vary across Hispanic/Latino background groups with distinct ancestral admixture. We analyzed Ξ΅2 and Ξ΅4 allele associations with AD biomarkers using survey-weighted linear regression models, adjusting for demographic covariates. Secondary analyses examined genetic analysis group- and ancestry-specific effects. Ξ΅4 was associated with lower AΞ²42/40 and higher p-tau181and GFAP levels, but not with NfL, suggesting its role in AΞ² and tau deposition and neuroinflammation. Ξ΅4 associations were stronger in those with higher European and lower African ancestry. These findings expand on prior studies suggesting that genetic ancestry modifies APOE-associated AD risk in Hispanic/Latino populations and highlight the importance of capturing ancestry-based heterogeneity in AD biomarker research.

Current in vitro enzyme inhibition assays often involve subjective data analysis based on the researcher's experience. In this study, we developed a multi-dimensional quantitative integration platform (MDQIP) that uses a model to objectively calculate and rank compound activities, addressing the limitations of traditional "experience-driven" evaluations, accelerates the screening and evaluation of potential AChE inhibitors from Red Gastrodia elata, offering a more efficient approach to drug discovery. Ultrafiltration-LC screening identified parishin A as having the most stable binding, with binding degree and recovery rates of 98.85% and 99.39%, respectively. Molecular docking revealed that parishins A and C were the strongest AChE inhibitors, exhibiting stable binding through hydrogen bonds, Ο-alkyl, and Ο-Ο interactions. Molecular dynamics simulations confirmed the stability of these compounds, with binding energies of -82.65Β Β±Β 4.24 andΒ -Β 80.69Β Β±Β 4.19Β kcal/mol. Enzyme kinetics showed that parishins A and C are mixed-type inhibitors, with IC Show less

A signature of 16 serum proteins that were previously profiled using the aptamer-based Somascan technology highlighted the roles of the e2 allele of APOE in lipid regulation via apolipoprotein B (APOB) and apolipoprotein E (APOE) and in inflammation. Here, the serum protein signature of APOE is validated and expanded using a combination of mass-spectrometry, ELISA, Luminex, blood transcriptomics, and antibody-based Olink serum proteomics. Some of the findings were replicated in the UK Biobank using antibody-based Olink serum proteomics. This analysis replicated the association between APOB and the e2 allele of APOE, detected a new, robust pattern of association between APOE genotypes and the serum level of APOE, and discovered new associations between APOE genotypes and the complex of apolipoproteins APOC1, APOC2, APOC3, APOC4, APOE, APOF, and APOL1. In addition, 13 new proteins correlated with APOE genotypes. This extended signature includes granule proteins CAMP, CTSG, DEFA3, and MPO secreted from neutrophils and points to olfactomedin 4 (OLFM4) as a new target for the prevention of Alzheimer's disease.

This first-in-human Phase I study evaluated the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of KN069, a novel dual Glucagon-like peptide-1 receptor agonist (GLP-1RA)/Glucose-dependent insulinotropic polypeptide receptor (GIPR) antagonist in Chinese men with overweight/obesity. This randomised, double-blind trial included a single ascending dose (SAD; 12-120βmg, Nβ=β36, 3:1 active-to-placebo) and a multiple ascending dose (MAD; Nβ=β12, dose escalation 15-60βmg) phase. Safety was assessed via adverse events (AEs) and compliance. PK was analysed using a sandwich enzyme-linked immunosorbent assay (ELISA) for Intact and Total KN069. PD included measurements of body weight, waist circumference, body mass index (BMI) and metabolic parameters. Immunogenicity was assessed by detecting anti-drug antibodies (ADA). KN069 was well tolerated, with predominantly mild-to-moderate gastrointestinal adverse events. PK showed dose-proportional exposure (12-90βmg) with a long half-life for Total KN069 (899.74-1099.01βh). In the SAD part, preliminary dose-dependent weight reductions were observed, with maximum early changes at Day 7 (90βmg: -4.71% vs. placebo: -0.41%) and sustained for up to 133βdays. In the MAD part, Group B (60βmg) achieved a -2.57% mean weight reduction from baseline at Day 25, alongside a significant decrease in waist circumference (pβ=β0.0446). Metabolic improvements included lower fasting glucose, triglycerides, uric acid and elevated insulin/C-peptide. KN069 exhibits favourable safety, long-acting PK and preliminary dose-dependent weight reduction alongside expected pharmacologic metabolic effects, supporting further clinical development. gov Identifier: NCT06547775.

Validate the clinical utility of exosome cargo (miRNAs/proteins) and NLRP3/BDNF as key regulatory molecules for acupuncture-mediated spinal cord injury (SCI) recovery. From the establishment of the database to May 2025, a literature search was conducted on PubMed, and Embase, using keywords ["exosome cargo" or "exosome"], ["acupuncture" or "acupuncture and moxibustion" or "electroacupuncture" or "EA"], ["spinal cord injury" or "SCI"], ["immune regulation"], ["inflammatory reaction"], ["neuroregeneration" or "nerve"]. Including peer-reviewed studies on human/animal models, articles that do not meet the requirements are excluded. Preclinically, MSC-exosomal miR-145-5p suppressed TLR4/NF-ΞΊB signaling, reducing spinal IL-1Ξ² by 47% in SD rats. Schwann cell-exosomal MFG-E8 activated SOCS3/STAT3, increasing M2 macrophage CD206 by 63% and raising rat BBB scores by 3.8 points; Treg-exosomal miR-2861 upregulated tight junction proteins (occludin/ZO-1) to repair the blood-spinal cord barrier. Acupuncture (EA at GV14/GV4) upregulated spinal BDNF by 72% and NGF by 58% via Wnt/Ξ²-catenin, while EA at GV6/GV9 downregulated NLRP3 by 42-58% and TNF-Ξ± by 35-47%. Clinically, EA at EX-B2 increased ASIA scores by 3.2Β±1.1 points (Guo et al). Besides, 5x/week EA improved ASIA vs 3x/week (+6.4 points). EA+exercise reduced MAS by 1.6-2.9 points, with outcomes correlated to peripheral NLRP3 reduction, BDNF elevation, and MBI/WISCIII increases. Exosome cargo (miR-145-5p/MFG-E8) and NLRP3/BDNF are key regulatory molecules underlying acupuncture-mediated SCI recovery. However, limitations (small RCT samples, heterogeneous acupuncture protocols, unstandardized exosome isolation) hinder translation. Future work should focus on standardized biomarker detection, exosome engineering, and large-scale clinical trials. Show less

The global obesity epidemic necessitates therapies that enhance energy expenditure. Non-shivering thermogenesis (NST) in brown/beige adipose tissue represents a promising target, with fibroblast growth factor 21 (FGF21) emerging as a critical regulator linking environmental stimuli to adipose plasticity and mitochondrial function. However, the precise mechanisms of FGF21 secretion and its specific role in adipose tissue browning and subsequent NST potentiation remain incompletely elucidated. FGF21 regulates NST via distinct spatiotemporal mechanisms. Acute cold exposure triggers hepatic FGF21 secretion through a Ξ² FGF21 exhibits dual regulation: hepatic (acute lipid mobilization) and adipose-based (chronic browning); adipose-targeted FGF21 delivery is essential for therapeutic efficacy, and future studies should integrate FGF21 with UCP1-independent pathways (e.g., creatine/succinate cycles) to advance obesity treatment.

This study investigated the neuroprotective effects and mechanisms of cycloastragenol (CAG) on oxidative stress and neurological function in cerebral ischemia-reperfusion injury (CIRI) and oxygen-glucose deprivation/reoxygenation (OGD/R) models. In vivo, rats were given oral CAG daily for 28 days before CIRI induction. Cerebral infarction and hippocampal injury were assessed using TTC, Nissl, and HE staining. Neurological scores, morris water maze, grip strength tests, and brain water content were used to evaluate functional outcomes. Oxidative stress was determined by biochemical assays, DHE staining, and transmission electron microscopy, while Western blotting was performed to measure neuroprotective proteins. In vitro, primary neurons were treated with CAG and subjected to OGD/R. Cell viability was tested by CCK-8 assay, apoptosis and mitochondrial membrane potential were analyzed by flow cytometry, ROS levels were quantified, and MDA, SOD, and GSH were measured biochemically. Western blot further evaluated BDNF and NeuN expression to confirm in vivo findings. In vivo, CAG reduced infarct volume and edema, improved neurological deficits, preserved the structural integrity of neurons in the hippocampal CA1 region. CAG also promoted motor function recovery, markedly reduced MDA levels, increased SOD and GSH activity, and upregulated BDNF and NeuN expression. In vitro, CAG enhanced cell viability in the OGD/R model, reduced apoptosis, restored mitochondrial membrane potential, and significantly suppressed oxidative stress induced by ischemia-reperfusion. CAG effectively alleviated injury caused by cerebral and cellular ischemia-reperfusion by maintaining redox homeostasis, inhibiting oxidative stress, and promoting the expression of neuroprotective proteins, demonstrating promising neuroprotective potential.

Depression is a debilitating psychiatric disorder with high prevalence and suicide risk, imposing significant burdens on global health. Against this global health burden, the active ingredients of Gekko gecko Linnaeus (AIGG), a traditional Chinese medicine (TCM), have shown empirical antidepressant effects. However, their specific pharmacological mechanisms remain unclear. This study systematically elucidated the antidepressant mechanisms of AIGG by integrating GC-MS-based component analysis, network pharmacology, molecular docking, and a corticosterone (CORT)-induced depressive mouse model. GC-MS identified 10 bioactive compounds (including fatty acids) in AIGG. Network pharmacology screening of 51 potential targets revealed significant enrichment in synaptic transmission and cAMP pathways. Molecular docking confirmed strong binding affinities between AIGG-derived compounds and key targets. In vivo experiments demonstrated that AIGG significantly reversed depression-like behaviors in both forced swim and tail suspension tests, suppressed Interleukin-6 (IL-6), tumor necrosis factor Ξ± (TNF-Ξ±), and elevated Ξ²-nerve growth factor (Ξ²-NGF) levels, attenuated neuroinflammatory infiltration and neuronal apoptosis in brain tissue, and upregulated protein expression of protein kinase cAMP-activated catalytic subunit alpha (PRKACA), brain-derived neurotrophic factor (BDNF), and postsynaptic density protein 95 (PSD95). The study confirmed that AIGG alleviates depression by activating the cAMP-PRKACA-BDNF axis to restore synaptic plasticity, providing a novel natural product-based strategy for treatment of the resistant depression.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a highly prevalent chronic liver disease worldwide and is closely associated with obesity, diabetes, and other metabolic disorders. Because MASLD progression poses serious health risks, elucidating the underlying mechanisms is essential to guide early intervention and therapeutic strategies. Proteomic analysis was used to identity high-fat diet (HFD)-induced proteins in mouse liver. Galectin-1 (GAL1) expression was assessed via immunohistochemistry in human liver tissues. Liver-specific GAL1-deficient mice were generated using adeno-associated virus. Mice were fed either a chow diet or an HFD. Functional studies were performed in cell lines using western blotting, RT-qPCR, immunofluorescence, co-immunoprecipitation, mass spectrometry, and molecular docking analysis. GAL1 expression was elevated in liver tissues from patients with MASLD and in mouse models. Liver-specific GAL1 knockdown alleviated hepatic steatosis and enhanced fatty acid oxidation (FAO). Mechanistically, GAL1 competitively bound to the BRCT domain of poly (ADP-ribose) polymerase 1 (PARP1), thereby interfering with its interaction with the WW domain -containing E3 ubiquitin protein ligase 2 (WWP2). Hepatic GAL1 knockdown promoted the PARP1 -WWP2 interaction and subsequently facilitated ubiquitin-dependent degradation of PARP1. This degradation led to increased NAD Hepatic deficiency of GAL1 alleviates hepatic steatosis by enhancing FAO through promotion of ubiquitin-dependent PARP1 degradation, thereby restoring NAD Show less

Dual GIP/GLP-1 receptor agonists have gained significant attention in clinical applications because of their remarkable efficacy in reducing obesity and type 2 diabetes. However, the mechanisms by which these dual agonists affect systemic metabolism remain elusive. To investigate the effects of a novel dual-receptor agonist, THDBH120, on systemic metabolism in obese individuals and the specific roles of GIPR and GLP-1R in modulating systemic and adipose tissue metabolism. To evaluate the intrinsic properties of THDBH120, we conducted a potency assay by using HEK293 cell lines overexpressing either human GIPR or GLP-1R and measured the accumulation of cAMP as a downstream second messenger following receptor activation. To evaluate the efficacy of THDBH120 on systemic metabolism, we used obese rodents and nonhuman primate species that received various doses and frequencies of THDBH120. To determine the metabolic roles of GLP-1R and GIPR in mediating the beneficial effects of THDBH120, we used GLP-1R- and GIPR-knockout mouse models treated with THDBH120, the GLP-1R agonist semaglutide, or the GIPR agonist LAGIPRA and performed transcriptomic sequencing analyses of adipose tissues. THDBH120 is a novel long-acting dual GIPR/GLP-1R agonist that has superior weight loss and metabolic improvement effects in rodents and mammals. The activation of GLP-1R by semaglutide or THDBH120 improved lipid metabolism, whereas the activation of GIPR by LAGIPRA or THDBH120 alleviated inflammation. THDBH120 improved lipid metabolism via GLP-1R-mediated pathways and mitigated inflammation by activating GIPR-associated pathways in the adipose tissues of obese mice. Both GLP-1R and GIPR are important in mediating the beneficial effects of dual receptors on systemic metabolism. THDBH120 is a novel long-acting dual GIPR/GLP-1R agonist that has potential clinical applications. Show less

Elevated lipoprotein(a) [Lp(a)] is a genetically determined, causal risk factor for atherosclerotic cardiovascular disease, but effective therapies remain limited. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are primarily used to lower low-density lipoprotein cholesterol (LDL-C), yet their effects on Lp(a) have been inconsistently reported. This umbrella review synthesizes meta-analytic evidence on PCSK9 inhibitors and Lp(a). We systematically searched PubMed, Embase, Web of Science, and Cochrane Library through April 2025 for meta-analyses of randomized controlled trials (RCTs) comparing PCSK9 inhibitors (alirocumab, evolocumab, inclisiran) with placebo or standard therapy. The primary outcome was mean percentage change in Lp(a). Methodological quality was assessed using the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), and evidence certainty was graded with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Overlap of primary trials was quantified using the Corrected Covered Area (CCA), and sensitivity analyses were performed to account for overlapping evidence. Twenty-one meta-analyses (116 RCTs; 231,796 participants) were included. The PCSK9 inhibitors consistently reduced Lp(a): evolocumab (29.68-46.68%; high certainty), alirocumab (18.55-26.46%; high certainty), and inclisiran (18.00%; high certainty). Higher biweekly doses yielded larger decreases (e.g., alirocumab 150 mg: 24.6%; evolocumab 140 mg: 26.8%, high certainty). Reductions were dose-dependent and broadly consistent across populations, comparators, follow-up durations, and baseline Lp(a). The Lp(a) reductions correlated modestly with LDL-C (Ξ² = 0.28; 95% CI 0.07-0.49) and apolipoprotein B (apoB) (Ξ² = 0.33; 95% CI 0.03-0.63). Concomitant reductions in LDL-C, apoB, and major adverse cardiovascular events were supported by high and moderate certainty evidence. Safety was favorable, with injection-site reactions being the most common adverse event. Sensitivity analyses confirmed robustness of findings after accounting for overlapping trials. The PCSK9 inhibitors, particularly evolocumab 140 mg every 2 weeks, significantly lower Lp(a) alongside LDL-C and apoB. These findings highlight the consistent Lp(a)-lowering effect of PCSK9 inhibitors. However, the observed cardiovascular benefits are largely attributable to concomitant LDL-C reduction, and the incremental contribution of Lp(a) lowering remains uncertain. Confirmation from outcome trials specifically designed to target Lp(a) is required. PROSPERO CRD420251048597. Show less

Current infant formulas lack the native multilayer structure of breast milk fat globule membrane (MFGM), impacting lipid digestion. In this study, the inner layer material and concentration of the biomimetic fat globule membrane were optimized by comparing particle size, Zeta-potential and interface protein load. It was found that compared with sodium caseinate (CN) and whey protein (WP), when the lactoferrin (LF) concentration was 2Β %, the particle size was lower (277.85Β Β±Β 6.15Β nm) and Zeta-potential value was higher (19.67Β Β±Β 1.27 mv). Using milk phospholipid (MPL) as the outer layer material, when the MPL concentration was 2Β %, the emulsion had a smaller particle size (291.33Β Β±Β 1.15Β nm) and a better stability (10.22Β Β±Β 0.62Β %). Therefore, the biomimetic multilayer membrane was constructed by electrostatic layer-by-layer deposition of 2Β % LF and 2Β % MPL. Combining Fluorescence and Fourier transform infrared spectroscopy (FTIR), the interaction between LF and MPL molecules in the LF-MPL multilayer structure is primarily a spontaneous, endothermic process driven by hydrophobic forces, exhibited superior stability (except thermal stability) than LF monolayer membrane. The results of in vitro digestion showed that compared with LF, WP and WP-MPL emulsions, LF-MPL emulsions had the highest free fatty acid (FFA) release rate of 69.97Β %. LF-MPL enhanced gastric stability and promoted intestinal lipolysis and improved the degree of lipid digestion. In addition, LF-MPL promoted the absorption and utilization of triglyceride (TAG) in cells and animals, and secretion and upregulated lipid absorption genes (FATP4, DGAT1, APOB, APOA4, MTTP). These findings demonstrate that biomimetic LF-MPL multilayers improve lipid digestion, absorption, and bioavailability, providing a theoretical basis for designing more breast milk-like infant formulas.

Autophagy supports clear cell renal cell carcinoma (ccRCC) progression, yet its upstream regulatory mechanisms remain to be fully defined. Integrating bulk, single-cell, and spatial transcriptomics, we identify a regulatory axis wherein the transcription factor ZBED6 activates the expression of the autophagy-initiating kinase PIK3C3 via the repression of IGF2, thereby driving pro-tumorigenic autophagy. Spatial analysis confirms the co-localization of ZBED6 and PIK3C3 in tumor tissues. Using genes associated with this axis, we develop a six-gene prognostic signature that stratifies patients with distinct survival outcomes and differential responses to immunotherapy and targeted therapy. Functional assays show that ZBED6 promotes ccRCC cell proliferation, migration, and invasion. This work elucidates a pathway governing autophagy in ccRCC and provides a framework for prognostic assessment and precision therapy. Show less

Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2-3-fold increase in neuropsychiatric co-morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ongoing pain to emotional disorders. This review systematically explores epigenetic signatures in supraspinal integration hubs, notably the limbic-paralimbic networks and prefrontal regulatory circuits. The identified epigenetic signatures encompass dysregulation of DNA methyltransferases (DNMTs), RNA modifications, histone post-translational modifications and locus-specific alterations, including aberrant methylation at the brain-derived neurotrophic factor (BDNF), opioid ΞΌ receptor and transient receptor potential ankyrin 1 (TRPA1) gene loci. Additionally, they involve dysfunction of the glucocorticoid receptor (GR)/corticotropin-releasing factor (CRF) axis via epigenetic modulation. Building on these findings, we evaluate therapeutic strategies addressing epigenetic dysregulation. While preclinical data demonstrate the efficacy of histone deacetylase (HDAC) and DNMT inhibitors, clinical translation faces significant barriers, including limited blood-brain barrier permeability. Notably, our analysis highlights the benefits of combining pharmacological interventions with non-invasive neuromodulation for enhanced co-morbidity management. Looking forward, this review proposes innovative approaches that leverage CRISPR-based chromatin editing platforms, biomimetic nanocarriers for neuron-specific delivery and closed-loop neuromodulation integrating real-time biomarker feedback, collectively establishing a precision medicine framework for pain or neuropsychiatric co-morbidities.

One important element impacting meat quality is fat metabolism, which mainly affects meat features through intramuscular fat deposition. Chinese native yellow-feathered broilers and white-feathered broilers differ significantly in intramuscular fat concentration. This study used transcriptomic and metabolomic sequencing technologies to identify a total of 173 differentially expressed genes and 259 differential metabolites in the pectoral muscles of Chahua Chicken No. 2 and Cobb broiler in order to explore the genetic mechanisms by which lipid metabolism influences meat quality in Chinese indigenous yellow-feathered and white-feathered broilers. These included differentially expressed genes like FABP1, LPL, ELOVL7, SLC27A1, MOGAT1, and ULK2, which were enriched in pathways relevant to lipid metabolism and showed strong associations with Ξ³-linolenic acid and palmitaldehyde, two distinct metabolites. In order to develop local chicken germplasm resources and breed superior indigenous chicken varieties, these candidate genes could serve as the genetic foundation for the variations in meat quality and lipid metabolism between Chinese native yellow-feathered and white-feathered broilers.

This study employs latent profile analysis (LPA) to identify potential categories of nurse burnout and to analyze differences in characteristics and influencing factors across burnout categories. From June to August 2025, a mixed sampling approach combining convenience and snowball sampling was used to recruit nurses from hospitals of varying levels in Southwest China. Three tools were used for data collection: A self-designed routine information questionnaire, Maslach Burnout Inventory-General Survey (MBI-GS) and Practice Environment Scale of the Nursing Work Index (PES-NWI), LPA identifies potential categories of nurses' professional burnout and uses multivariate logistic regression analysis to explore the factors associated with these categories. This study comprised a total of 809 participants. LPA identified four distinct latent classes of nursing burnout: Class 1, low-burnout-high-efficacy (11.5%); Class 2, mild-burnout-unfulfilled (33.9%); Class 3, moderate-burnout-exhausted (44.6%); and Class 4, severe-burnout-dysfunctional (10.0%). Multivariate logistic regression analysis showed that age, years of work experience, hospital level, nurses' participation in hospital management, nursing quality standards, staffing and resource adequacy, and medical care cooperation are significant predictors of burnout among nurses ( Nurse burnout in southwest China is mainly moderate to severe and exhibits distinctive characteristics. It is recommended to implement personalized interventions tailored to the specific characteristics of nurses' professional burnout to alleviate the situation. Particular attention should be given to nurses with fewer than five years of experience by providing enhanced job support and psychological assistance to help them navigate critical periods of professional burnout. These measures aim to safeguard nurses' physical and mental health, improving the overall quality of nursing, and promoting the healthy development of global medical care. Show less

Pancreatic cancer (PC) is a common gastrointestinal malignancy whose initiation and progression may be closely linked to the gut microbiota. Previous research indicates that Scutellaria barbata D. Don and Scleromitrion diffusum (Willd.) R.J. Wang (SB-SD) exhibit diverse biological activities, such as anti-inflammatory, antioxidant, and antitumor effects, though their precise regulatory mechanisms are not fully elucidated. Here, we treated PC cells with SB-SD to assess its impact on cell viability, apoptosis, migration, and cell cycle progression, while Western blotting analyzed the expression of HSP90AA1, MAPK3, p53, CDK1, and p21. We also established a pancreatic cancer xenograft model in nude mice to evaluate the in vivo inhibitory effect of SB-SD on tumor growth. Furthermore, we employed metagenomic sequencing, untargeted metabolomics, and quantitative proteomics to comprehensively profile changes in the gut microbiota, serum metabolites, and differentially expressed proteins, with Western blotting subsequently validating BCKDK, GATM and p53 expression. The results show that SB-SD significantly inhibited PC cell proliferation, promoted apoptosis, and induced S/G2 phase cell cycle arrest, potentially via modulation of the HSP90AA1/MAPK3 signaling pathway. Measurements of tumor volume and weight, complemented by histopathological analysis, confirmed that SB-SD effectively suppressed the growth of PANC-1 xenograft tumors. Integrated multi-omics analyses suggest that the antitumor effects of SB-SD may involve the modulation of key gut microbes like Bacteroides caccae and Lactobacillus, the promotion of choline metabolism, and the regulation of BCKDK and GATM. Together, these findings not only corroborate the direct antitumor activity of SB-SD against pancreatic cancer but also offer novel mechanistic insights by constructing a microbiota-metabolite-protein interaction network.

Diabetic retinopathy (DR) is a leading cause of vision loss in working-age adults and often progresses to proliferative diabetic retinopathy (PDR) with irreversible complications. Anti-vascular endothelial growth factor (VEGF) therapy remains the first-line treatment; however, resistance poses a significant challenge, necessitating alternative therapeutic targets. This study explores the role of angiopoietin-like protein 4 (ANGPTL4) in PDR pathogenesis, emphasizing vascular-immune-lymphatic interactions. We found significantly elevated ANGPTL4 and VEGF-C levels in the vitreous humor of patients with PDR, which were not affected by anti-VEGF therapy. In vivo, full-length ANGPTL4 and its C-terminal fragment promoted pathological angiogenesis and lymphatic-like remodeling in diabetic murine retinas, characterized by increased lymphatic vessel endothelial hyaluronan receptor 1, prospero homeobox 1, and VEGF receptor 3 (VEGFR3) expression. Single-cell sequencing further revealed ANGPTL4-driven immune dysregulation, with abnormal infiltration of CD4+ T cells and dendritic cells. Knockdown of ANGPTL4 in mice with oxygen-induced retinopathy alleviated retinal hypoxia, neovascularization, and vascular leakage. Mechanistically, retinal hypoxia markedly increased ANGPTL4 expression levels in the retina, which activated the activator protein-1 (AP-1) transcription factor complex and promoted Cd83 transcription in mouse heart microvascular endothelial cells. Additionally, ANGPTL4 bound to neuropilin-1 (NRP1)/VEGFR3, driving human lymphatic endothelial cell proliferation and lymphatic vessel ingrowth from the optic nerve sheath into the retina, a finding that suggests a novel pathway independent of angiopoietin-Tie signaling. These findings establish ANGPTL4 as a key mediator of immune-vascular interactions in PDR and a potential therapeutic target to address both pathological angiogenesis and lymphatic dysfunction. Some patients with proliferative diabetic retinopathy (PDR) have poor responses to anti-vascular endothelial growth factor (anti-VEGF) therapy. This situation highlights the need for additional therapeutic approaches. In proliferative diabetic retinopathy, what is the role of ANGPTL4 that differs from VEGF? We found that ANGPTL4 is elevated in the vitreous humor of patients with PDR who are poorly responsive to anti-VEGF therapy. ANGPTL4, particularly its C-terminal fragment, causes retinal lymphatic-like remodeling in diabetic mice. This study provides novel insights into the complex interplay between immune activation, neovascularization, and lymphatic-like remodeling in PDR. Our findings deepen our understanding of PDR pathophysiology and propose a promising therapeutic target. Show less

Cognitive impairment is a significant health concern in aging populations, but the interplay between biological aging, lifestyle factors, and genetic susceptibility remains unclear. This study examined whether accelerated biological aging is associated with cognitive impairment, whether lifestyle modifies this association, and how genetic background influences these relationships in Chinese older adults. In this cross-sectional study (2022-2023), 7033 participants from southwestern China were included. Accelerated biological aging was calculated as the residual difference between biological age (based on 10 biomarkers) and chronological age. Lifestyle was assessed via a composite index (smoking, alcohol, physical activity, diet, sleep). Cognitive function was measured using the Chinese Mini-Mental State Examination (C-MMSE), and genetic risk was evaluated through polygenic scores and APOE Ξ΅4 status. Linear and logistic regression models assessed associations between accelerated aging and cognition. Accelerated biological aging was associated with lower MMSE scores (βΞ² = -0.243, 95% CI: -0.354, -0.133) and higher cognitive impairment prevalence (ORβ=β1.098, 95% CI: 1.040, 1.158). An unhealthy lifestyle exacerbated cognitive impairment in biologically older individuals (RERIβ=β0.25). Those with both accelerated aging and unhealthy lifestyle had the lowest MMSE scores (βΞ² = -1.424, 95% CI: -1.846, -1.003) and highest odds of cognitive impairment (ORβ=β1.467, 95% CI: 1.194, 1.803). These effects were consistent across all genetic background subgroups. Accelerated aging was associated with lower cognitive function, especially in individuals with unhealthy lifestyles, regardless of genetic susceptibility. This highlights lifestyle modification as a potential intervention target for aging-related cognitive impairment. Show less

Prior studies indicate that allyl isothiocyanate (AITC) alleviates metabolic dysfunction-associated steatotic liver disease (MASLD). The vitamin D receptor (VDR) is known to exert protective effects in MASLD; however, whether AITC alleviates MASLD through VDR remains unclear. To clarify the function and underlying mechanisms of AITC in MASLD AML-12 cells were exposed to 300 ΞΌM palmitate acid (PA) for 24 hours to establish an To establish an AITC provides a robust molecular basis for improving MASLD by activating hepatic VDR and driving the downstream HNF-4Ξ±/MTTP/ApoB signaling pathway. This pathway reduces hepatic lipid accumulation, promotes FA Ξ²-oxidation, and improves insulin resistance, establishing AITC as a promising treatment for MASLD. Show less
