Obesity is a well-documented cardiovascular risk factor. Here, we sought to investigate whether obesity causes subclinical cardiac remodeling and heart failure (HF), and if so, to perform a systematic scan of the plasma protein for novel drug targets. We leveraged visceral adipose tissue (VAT), waist circumference (WC), and waist-to-hip ratio (WHR)-all adjusted for body mass index (BMI)-as indicators of obesity. Two-sample Mendelian randomization (MR) analyses were used to estimate the independent, causal effects of obesity on cardiovascular magnetic resonance (CMR)-derived cardiac traits and HF risk. Mediation analyses followed by druggability assessment were conducted to identify promising protein targets for therapeutic translation. Genetically determined VATadjBMI, WCadjBMI, and WHRadjBMI presented broad causal associations with alterations of distinct cardiac phenotypes, most of which remained significant after controlling for obesity-induced cardiometabolic risk factors, including hypertension, type 2 diabetes, and adverse lipid profiles. By contrast, WHRadjBMI is the only independent causal predictor for HF risk. Of 142 proteins with mediating effects, scavenger receptor class A member 5 (SCARA5), membrane cofactor protein (CD46), and alpha-1-antichymotrypsin (SERPINA3) may contribute to the early-stage adverse cardiovascular effect of obesity, whereas apolipoprotein C-III (APOC3), mitochondrial aldehyde dehydrogenase 2 (ALDH2), and chordin-like protein 2 (CHRDL2) may further promote the development of obesity-driven HF. Medications targeted at these candidate proteins are either approved or under evaluation in clinical trials. Our MR findings provided genetic evidence for the direct, causal associations of obesity with cardiac remodeling and HF, while also outlining druggable proteins as promising therapeutic targets.

Atherosclerotic plaque instability is a direct cause of cardiovascular and cerebrovascular events. In this study, a mitochondria-targeted liposome (LIP), modified with triphenylphosphonium (TPP) to enable specific mitochondrial delivery, was innovatively constructed to encapsulate a PCSK9 inhibitor (TPP-LIP@PCSK9). The aim was to explore a novel strategy for stabilizing plaques by restoring mitochondrial function in endothelial cells. Characterization results showed that TPP-LIP@PCSK9 possesses favorable nano-characteristics, and its targeting capability was confirmed through mitochondrial co-localization experiments.

High-dose methotrexate for pediatric cancer treatment is frequently associated with mucositis, which can lead to delayed or discontinued treatment and impact survival. While individual genetic variants have been implicated, the cumulative impact of genetic variation within relevant biological pathways remains unexplored. We evaluated single nucleotide polymorphisms across 18 pathways previously identified as relevant to mucositis in 278 pediatric patients with acute lymphoblastic leukemia from six academic health centers across Canada. Pathway enrichment was assessed using the Joint Association of Genetic variants tool, and a predictive model was developed using XGBoost, a supervised machine learning algorithm based on gradient-boosted decision trees. Pathway enrichment identified significant associations in IL6 (P = 0.04) and WNT/β-catenin (P = 0.048) signaling pathways. The predictive model (area under the curve [AUC] = 0.76) highlighted single nucleotide polymorphisms associated with inflammation- and mucosa-related genes, including PRKCD, IL17B, MAST3, and CAPN9, with both risk and protective effects. Model performance dropped by 0.15 in AUC (from 0.76 to 0.61) after removing single nucleotide polymorphism features, underscoring their predictive value. This pathway-informed approach identifies genetic contributors to methotrexate-induced mucositis and supports polygenic risk prediction. Our findings provide a foundation for individualized toxicity risk profiling and suggest potential therapeutic targets to mitigate treatment-limiting mucositis in pediatric oncology. 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 β 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.

ApoB (apolipoprotein B)-containing lipoproteins are causal risk factors for atherosclerotic coronary artery disease (CAD). Since human cathelicidin LL-37 binds to ApoB-100 in this pathological context, we investigated whether the circulating LL-37-ApoB-100 complex could serve as a biomarker for CAD. We performed surface plasmon resonance and protein-protein docking to demonstrate the direct LL-37-ApoB-100 interaction. We developed a specific polyclonal antibody against the complex and measured its levels in human atherosclerotic plaques and plasma, as well as in We identified that LL-37 directly interacted with multiple distinct binding sites on ApoB-100. Plasma levels of LL-37-ApoB-100 complex were significantly elevated in human patients with atherosclerosis. Consistently, levels of this complex were positively correlated with atherosclerotic plaque area in Circulating LL-37-ApoB-100 levels are strongly associated with angiographically documented CAD, highlighting LL-37-ApoB-100 as an independent predictor for CAD.

This study established a hyperlipidemia model by feeding Sprague-Dawley rats a high-fat diet for 8 weeks. The rats were randomly assigned to the following groups: model group, atorvastatin calcium group(4.8 mg·kg~(-1)), low-, medium-, and high-dose Tanyu Tongzhi Optimization Decoction(TYTZD) groups(3.6, 7.2, and 14.4 g·kg~(-1)), and a normal diet control group. After 4 weeks of continuous administration, hematoxylin-eosin(HE) and oil red O staining were used to observe liver pathological changes and lipid infiltration. Automatic biochemical analyzer were performed to assess blood lipid profiles, coagulation function, and liver function. Transcriptomic and proteomic analyses were employed to identify differentially expressed genes(DEGs) and proteins(DEPs), followed by enrichment analysis. The MCODE algorithm was applied to classify DEGs and DEPs into modules, and network separation index(S₍AB)) was calculated to assess module separation, enabling construction of a gene-protein co-expression network for core target screening. The diagnostic accuracy of core targets was evaluated by area under the receiver operating characteristic(ROC) curve(AUC), and ELISA was used to measure core target expression. Western blot detected the expression of core pathway-related proteins in liver tissue. RESULTS:: demonstrated that TYTZD significantly improved dyslipidemia, coagulation dysfunction, liver injury, hepatic pathology, and lipid infiltration in hyperlipidemic rats. Transcriptomic analysis identified 571 DEGs significantly reversed by TYTZD, mainly enriched in inflammatory signaling pathways such as Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB). Proteomic analysis identified 102 reversed DEPs, mainly involved in cholesterol metabolism pathways. Integrated analysis identified core targets including TLR4, tumor necrosis factor-α(TNF-α), integrin subunit alpha M(ITGAM), Toll-like receptor 2(TLR2), matrix metalloproteinase 9(MMP9), interleukin-1β(IL-1β), apolipoprotein E(APOE), and apolipoprotein C2(APOC2), all with AUC values greater than 0.70. ELISA showed that TYTZD intervention significantly downregulated MMP9, TNF-α, IL-1β, TLR2, ITGAM, and TLR4, and upregulated APOC2 and APOE. Western blot indicated that TYTZD reduced TLR4, p-NF-κB, and IL-1β protein expression in liver tissue. In conclusion, TYTZD may exert anti-hyperlipidemic effects through regulation of core targets such as ITGAM, TLR4, and APOC2, and by modulating the TLR4/NF-κB signaling pathway to intervene in inflammatory responses and cholesterol metabolism, thereby achieving multi-target, multi-pathway therapeutic effects against hyperlipidemia.

Vascular remodeling involves structural and functional vascular changes in response to injury, aging, and disease. A key pathological feature is vascular smooth muscle cells (VSMCs) phenotypic switching, which is accompanied by mitochondrial dysregulation. Metabolic reprogramming resembling the Warburg effect alongside mitochondrial oxidative damage collectively drive this pathological VSMC transdifferentiation. We hypothesized that targeting mitochondrial ROS could restore mitochondrial integrity and enhance oxidative phosphorylation (OXPHOS) to counteract both oxidative damage and metabolic reprogramming in cardiovascular diseases associated with vascular remodeling. We proposed that the uncharacterized membrane-associated protein FAM177A1 drives VSMC mitochondrial oxidative impairment and metabolic reprogramming, thereby promoting VSMC phenotypic switching and vascular dysfunction. We modeled vascular remodeling using global We identify FAM177A1 as a key mitochondrial regulator that drives VSMC switching through SIRT3-SOD2 axis disruption. Targeting FAM177A1 restores redox-metabolic homeostasis through scavenging ROS and improving OXPHOS, establishing it as a novel therapeutic target against vascular remodeling. Show less

Spinal cord injury (SCI) represents significant central nervous system trauma and has consistently been a focal point of research in the domain of neural regeneration and repair. Currently, there is no effective treatment available. Various modalities of magnetic stimulation have emerged for recovery from spinal cord injuries; however, the underlying mechanisms remain unclear, significantly hindering the application of magnetic stimulation technologies in treating such injuries. This study aims to elucidate these relevant mechanisms by establishing a simulated closed-loop magnetic stimulation system. In this study, we established a right hemisection model at T8 in mice and administered continuous simulated closed-loop magnetic stimulation targeting the left motor cortex and right L5 nerve root over six weeks. We subsequently utilized a spinal cord dorsal hemisection model to examine regeneration of the corticospinal tract (CST). Motor-evoked potential assessments and calcium imaging techniques were employed to explore neural circuit repair. Additionally, we integrated transcriptomics, proteomics, and metabolomics approaches to investigate related mechanisms. The findings indicate that simulated closed-loop magnetic stimulation effectively restores motor function in the hind limbs, promotes the regeneration of corticospinal tracts in mice with spinal cord injuries, and facilitates the reconstruction of sensorimotor circuits and functions within the spinal cord. Simulated closed-loop magnetic stimulation significantly enhances axonal regeneration of the CST following SCI. This effect may be mediated through the activation of the AMPK-CREB-BDNF signaling pathway, which promotes neurotrophic factor secretion and subsequently induces nerve axon regeneration. This study suggests that simulated closed-loop magnetic stimulation represents a promising therapeutic approach for the treatment for impaired gait following SCI. Show less

Hepatitis B virus (HBV) infection can cause liver damage through oxidative stress (OS) and immune-inflammatory responses. This study aims to explore the clinical significance of fibroblast growth factor 21 (FGF21) in the development and progression of chronic hepatitis B (CHB). A total of 336 participants were recruited, including 320 CHB patients and 16 healthy controls. The expression of FGF21, immune cytokines, and OS-related molecules in peripheral blood mononuclear cells (PBMCs) was detected using real-time quantitative polymerase chain reaction. The methylation level of the FGF21 gene promoter in PBMCs was detected using TaqMan probe-based quantitative methylation-specific PCR. The expression level of FGF21 in the peripheral blood of CHB patients was higher than that of HC, but the methylation level of the FGF21 promoter was lower than that of HC, especially in patients during the immune activation phase. The mRNA expression levels of CXCR3 and CCL5 in PBMCs of CHB patients during the immune activation and reactivation phases were higher than those in other clinical stages. Single-cell analysis revealed that CXCR3 and CCL5 expression in the immune tolerance and immune activation phases with high HBsAg expression was closely related to T lymphocytes (T cells) and natural killer cells (NK cells) and was highly expressed in CD4 and CD8 T cells and NK cells. In addition, the mRNA expression levels of Nrf2 and GPX4 in the reactivation phase were higher than those in other clinical stages. The mRNA expression level and methylation level of FGF21 in PBMCs of CHB patients were correlated with the viral load, immune inflammation, and OS levels during the antiviral treatment course of CHB. The methylation level of the FGF21 promoter has the potential to become a non-invasive biomarker for monitoring the progress of antiviral treatment in CHB.IMPORTANCEThis study conducted an in-depth exploration of the application of methylation detection technology, analyzing its value and driving mechanism in the oxidative stress and immune-inflammatory balance during the course of chronic hepatitis B. The study analyzed the methylation patterns of the FGF21 promoter and the expression levels of its receptor FGFR1, as well as the expression levels of chemokines CXCR3, CCL5, and oxidative stress factors GPX4 and Nrf2 in the immune tolerance period, immune clearance period, immune control period, and reactivation period of chronic hepatitis B. It clarified the association between these molecules and the FGF21/FGFR1 axis and revealed the synergistic or antagonistic mechanisms of these molecules in the oxidative stress and inflammatory vicious cycle. At the same time, this study also explored the value of FGF21 promoter methylation in disease diagnosis and prognosis, providing a theoretical basis for evaluating the antiviral treatment effect and disease progression of chronic hepatitis B.

Acute alcohol consumption is known to exert widespread physiological effects, yet the immediate impacts on metabolic biomarkers remain incompletely understood. The present randomized controlled trial was conducted to investigate the acute effects of a single episode of alcohol ingestion on various biomarkers in healthy individuals. A total of 45 male participants were recruited and randomized into an alcohol group (n = 40) and a control group (n = 5) at an 8:1 ratio. Volunteers in the alcohol group ingested 40% Absolut vodka within 15 min. Blood pressure, heart rate, and blood oxygen saturation were measured at 0 h, 1 h, 3 h, 5 h, 12 h, and 24 h. Venous blood samples were drawn at 0 h, 1 h, 5 h, 12 h, and 24 h after alcohol intake. Our results showed that levels of liver function markers, including α-fucosidase (AFU), albumin (ALB), and alkaline phosphatase (ALP), were significantly increased in the alcohol group compared to the control group. The 24-h area under curve (AUC) of AFU, ALB, and ALP were significantly higher in the alcohol group. The liver fibrosis maker collagen type Ⅳ (Ⅳ-C) tended to be higher at 1 h and 12 h in the alcohol group compared to the control group. Lipid levels, including triglycerides (TG), apolipoprotein A1 (APOA1), and the APOA1/APOB, were significantly elevated after alcohol ingestion, particularly at 5 h and 12 h. The 24 h-AUC of TG, APOA1, and APOA1/APOB were higher in the alcohol group than in the control group. Additionally, cardiac function indicators, including heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP), were significantly elevated in the alcohol group. SBP and DBP remained higher 24 h after alcohol ingestion compared to the control group. This study demonstrated that even a single episode of binge drinking could induce significant alterations of biomarkers related to liver function, cardiac function, and lipid profiles. These findings provided valuable insights into the short-term impact of alcohol on health and highlighted the importance of further research to explore the long-term implications of repeated acute alcohol exposure. Given the very small control group, these results should be interpreted as preliminary and confirmed in larger, more balanced randomized trials.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver condition, closely associated with obesity and type 2 diabetes mellitus. Despite its prevalence, there are no approved pharmacotherapies, making the search for effective treatments crucial. This study investigates the impact of vertical sleeve gastrectomy (VSG) on NAFLD, focusing on changes in bile acid metabolism as a potential therapeutic mechanism. We employed an ApoE-/- mouse model to simulate human NAFLD conditions. Mice were divided into two groups: one underwent VSG and the other served as a control. We monitored body weight, food intake, liver function, lipid profiles, and histological changes in hepatic tissues. Bile acid profiles were analyzed using Ultra Performance Liquid Chromatography coupled with Tandem Mass Spectrometry (UPLC-MS/MS). Post-VSG, mice exhibited significant weight loss and reduced food intake. Biochemical analyses showed substantial improvements in liver function tests (ALT and AST), lipid profiles (cholesterol and triglycerides), and glucose regulation. Histological examination revealed marked reductions in hepatic steatosis and inflammation. Notably, VSG led to significant alterations in bile acid profiles, particularly increased primary bile acids and decreased secondary bile acids, correlating with improved liver histology and metabolic parameters. Our findings suggest that VSG, beyond its role in weight reduction, significantly improves NAFLD. The surgery alters bile acid metabolism, which may contribute to its therapeutic effects. These results highlight the potential of VSG as a metabolic surgery for NAFLD and open avenues for exploring bile acid-related therapies. Show less

UK Biobank discovery cohort (n=10,229) for signature derivation, internal validation cohort (n=91,306), external validation cohort Whitehall-II (n=7,893), and three additional cohorts (two Western and ONE-IBD) for validation of key metabolic drivers. Primary outcomes were UPF-related circulating metabolic signatures and their associations with CD risk; secondary outcomes included evidence supporting causal roles of candidate metabolites and genetic pathways assessed by Mendelian randomization, colocalization, and gene-environment analysis. A UPF metabolic signature of 73 metabolites was constructed and validated across cohorts (Spearman ρ: 0.20-0.25). More pronounced UPF metabolic signature was associated with increased CD risk (HR The adverse effects of UPF on CD risk may be driven by a relative deficiency of protective metabolites such as DHA, apart from additive harm to metabolic depletion. This reframes UPF-related risk and highlighting potential targets for precision nutrition in CD prevention. Show less

Coronary heart disease (CHD) remains a leading cause of morbidity and mortality worldwide. Mitochondria-associated endoplasmic reticulum membranes (MAMs) have recently emerged as critical mediators in cardiovascular pathophysiology; however, their specific contributions to CHD pathogenesis remain largely unexplored. This study aimed to identify and validate MAM-related biomarkers in CHD through integrated analysis of transcriptomic sequencing data and Mendelian randomization, and to elucidate their underlying mechanisms. We analyzed two gene expression microarray datasets (GSE113079 and GSE42148) and one genome-wide association study (GWAS) dataset (ukb-d-I9_CHD) to identify differentially expressed genes (DEGs) associated with CHD. MAM-related DEGs were filtered using weighted gene co-expression network analysis (WGCNA). Functional enrichment analysis, Mendelian randomization, and machine learning algorithms were employed to identify biomarkers with direct causal relationships to CHD. A diagnostic model was constructed to evaluate the clinical utility of the identified biomarkers. Additionally, we validated the two hub genes in peripheral blood samples from CHD patients and normal controls, as well as in aortic tissue samples from a low-density lipoprotein receptor-deficient (LDLR-/-) atherosclerosis mouse model. We identified 4174 DEGs, from which 3326 MAM-related DEGs (DE-MRGs) were further filtered. Mendelian randomization analysis coupled with machine learning identified two biomarkers, DHX36 and GPR68, demonstrating direct causal relationships with CHD. These biomarkers exhibited excellent diagnostic performance with areas under the receiver operating characteristic (ROC) curve exceeding 0.9. A molecular interaction network was constructed to reveal the biological pathways and molecular mechanisms involving these biomarkers. Furthermore, validation using peripheral blood from CHD patients and aortic tissues from the Ldlr-/- atherosclerosis mouse model corroborated these findings. This study provides evidence supporting a mechanistic link between MAM dysfunction and CHD pathogenesis, identifying candidate biomarkers that have the potential to serve as diagnostic tools and therapeutic targets for CHD. While the validated biomarkers offer valuable insights into the molecular pathways underlying disease development, additional studies are needed to confirm their clinical relevance and therapeutic potential in larger, independent cohorts.

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 2 %, the particle size was lower (277.85 ± 6.15 nm) and Zeta-potential value was higher (19.67 ± 1.27 mv). Using milk phospholipid (MPL) as the outer layer material, when the MPL concentration was 2 %, the emulsion had a smaller particle size (291.33 ± 1.15 nm) and a better stability (10.22 ± 0.62 %). Therefore, the biomimetic multilayer membrane was constructed by electrostatic layer-by-layer deposition of 2 % LF and 2 % 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 69.97 %. 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.

Older adults' social participation is associated with frailty, but the transition patterns and their relationship with frailty remain unclear. This longitudinal study aims to explore the latent classes and transition patterns of social participation in older adults with chronic non-communicable diseases and to assess their relationship with subsequent frailty. The data set from the China Health and Retirement Longitudinal Study (CHARLS) in 2018 (T1) and 2020 (T2) was analyzed, including 4793 older adults. Latent profile analyses (LPA) and latent transition analyses (LTA) were employed to identify latent classes and the transition probabilities of social participation at T1 and T2. The ANCOVA was employed to examine the frailty index at T2 was compared across transition patterns. The LPA results supported a 4-class model labeled as inactive group, voluntary group, social interaction group, and omni-engaged group. The probability of transition from the other groups to the inactive group was significant (33.3 %, 53.8 %, 54.4 %). Age, residence, marital status, and other demographic characteristics can significantly impact transition patterns. However, after controlling for baseline frailty and other covariates, transition patterns were not significantly associated with T2 frailty levels. The short-term (two-year) effect of qualitative shifts in social participation on frailty may be limited when pre-existing health status is accounted for. Future interventions should prioritize sustained engagement and investigate the longer-term effects of both qualitative and quantitative changes in social participation. Show less

Indigenous chickens in tropical regions routinely survive high environmental temperatures (40-45 °C) that cause significant mortality and production loss in commercial breeds, yet the genetic mechanisms of thermotolerance remain poorly understood. This study integrated genome-wide selective scans across 14 geographically and climatically diverse chicken breeds with multi-tissue expression data, gene expression quantitative trait locus (eQTL) analysis, transcriptome-wide association study (TWAS), and cross-species phenome-wide association study (PheWAS) to validate candidate genes. We identified 25 high-confidence genes under selection, with ATP1A1, PLCB4, RYR2 and AKT3 forming a regulatory hub coordinating cardiovascular, calcium and survival signaling. These genes converge on interconnected adrenergic, calcium, and GnRH signaling pathways, with coordinated expression across heart, hypothalamus, and liver forming an integrated thermoregulatory axis. The eQTL integration analysis using ChickenGTEx data identified 359 tissue-specific cis-eQTLs in selected regions. Additionally, TWAS analysis linked ATP1A1 to 145 gene-trait associations across 13 tissues and 14 trait categories (hepatic regulation, β = -2.13, p = 4.21 × 10⁻¹²), and cross-species PheWAS validated conserved roles in cardiovascular function (RYR2, resting heart rate p = 4.9 × 10⁻¹²), and ionic homeostasis (ATP1A1, chloride p = 1.18 × 10⁻³). In parallel, we also identified robust genomic signatures of domestication in classic candidate genes (TSHR, TBC1D1, BDNF), highlighting how initial separation from Red Jungle Fowl and subsequent adaptation to diverse climates have shaped the genetic and physiological diversity of the domesticated chicken. Collectively, our results reveal an integrated cardio-neuroendocrine calcium network driving heat adaptation, providing potential targets for breeding heat-tolerant chickens. Show less

The mechanisms underlying individual variability in acupuncture analgesia among patients with chronic pain remain unclear. This randomized controlled trial investigated the core mechanisms of differential responses to acupuncture from genetic, neuroimaging, and transcriptomic perspectives in patients with chronic pain due to knee osteoarthritis (KOA). A total of 180 KOA chronic knee pain patients were randomly assigned to verum acupuncture (VA), sham acupuncture (SA), celecoxib (SC), placebo (PB), or waiting list (WL) groups (36 each). Over 2 weeks, VA/SA received 10 sessions, SC/PB oral medication for 14 days, and WL no intervention. Baseline 3.0T MRI 3D-T1 scans and genotyping (GABRB3 rs4906902, OPRM1 rs1799971, COMT rs4680, BDNF rs6265) were performed. Efficacy was assessed via VAS and WOMAC; responders/non-responders were defined by minimally clinically important difference. Chi-square test, logistic regression, voxel-based morphometry (VBM), and Allen Human Brain Atlas-based partial least squares regression were used. No significant difference in primary outcomes was observed between VA and SA, so they were combined as the acupuncture group (AG) to enhance statistical power. Only AG had a significant association between GABRB3 rs4906902 AG/GG genotype and acupuncture response (p < 0.05); other loci showed no correlation. AG/GG carriers in AG had lower gray matter volume in caudate head, putamen, and ventral striatum, with higher GABRB3 expression in these regions. Genetic polymorphisms at GABRB3 rs4906902 could influence the analgesic effect of acupuncture treatment in patients with KOA chronic knee pain, with AG/GG genotype carriers exhibiting superior analgesic effects. This finding may be associated with pain-modulating brain regions' gray matter volume reduction and upregulation of GABRB3 gene expression. Show less

Female mice were divided into four groups (n = 5 per group): C57BL/6 wild-type (WT), WT treated with probucol (WT + PBC), APP/PS1 transgenic (AD) mice, and AD treated with probucol (AD+PBC). Bone mineral density (BMD) was assessed by micro-CT. Levels of pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) along with bone metabolism markers including fibroblast growth factor 23 (FGF23), sclerostin, and brain-derived neurotrophic factor (BDNF) in bone and brain tissues were measured by ELISA. FOXO3a was knocked down in the bone marrow of APP/PS1 mice via stereotactic injection of lentiviral vectors. Expression of APP and FOXO3a in bone tissue was evaluated using RT-qPCR and Western blotting (WB). Mitochondrial damage in osteoblasts and neuronal cells was assessed by transmission electron microscopy (TEM). In vitro study, osteoblast differentiation and mineralization deficits were evaluated using Alizarin Red staining. WB was used to measure the expression of AKT, FOXO3a, autophagy and apoptosis related proteins. Probucol attenuated bone loss and mitochondrial damage in both APP/PS1 and FOXO3a-knockdown APP/PS1 mice, and improved cognitive impairment and neuronal ultrastructure in APP/PS1 mice. Furthermore, probucol attenuated Aβ42-induced osteoblast differentiation and mineralization via the AKT/FOXO3a signaling pathway in vitro. These findings demonstrate that probucol ameliorates AD-associated bone loss and Aβ42-induced osteoblast impairments by regulating AKT/FOXO3a signaling pathway. Show less

Angiopoietin-like protein 8 (ANGPTL8), a member of the angiopoietin-like protein (ANGPTL) family, is a physiological inhibitor of lipoprotein lipase (LPL), and plays a critical role in lipoprotein and triglyceride metabolism in response to nutritional cues. ANGPTL8 is implicated in a wide range of systemic and cellular processes and is closely associated with metabolic and cardiovascular diseases (CVD). Circulating ANGPTL8 is primarily secreted by the liver, with adipose tissue as a secondary source. Its expression is regulated by multiple transcription factors and microRNAs, and is responsive to fasting/refeeding states, hormonal signals, and stress conditions. In lipid metabolism, ANGPTL8 forms complexes with ANGPTL3 and ANGPTL4 to modulate LPL activity under fasting and feeding conditions. In glucose metabolism, ANGPTL8 plays a complex role. While some studies suggest it may improve glucose tolerance and insulin resistance, others indicate it could exacerbate glucose metabolism disorders and diabetes, or have no effect. Cardiovascular diseases are intricately linked to metabolic disorders and diseases. Increasing evidence also links ANGPTL8 to various cardiovascular pathologies, including atherosclerosis, hypertension, cardiomyopathy, cardiac hypertrophy, aortic aneurysm, and dissection. Given the strong interplay between metabolic dysregulation and CVDs, elucidating the role of ANGPTL8 in these processes is of significant interest. This review provides a balanced assessment of ANGPTL8's roles in key pathophysiological processes, highlighting its established functions in metabolism alongside its emerging involvement in CVDs. Understanding the diverse functions of ANGPTL8 in various tissues and metabolic states will lead to new opportunities for therapeutic intervention in cardiometabolic disorders. Show less

The Climate Change Anxiety Scale (CCAS) is an emerging psychometric instrument designed to assess climate change anxiety (CCA). This study aimed to preliminarily identify reference cutoff scores and core items of the CCAS in a Chinese adult population. We conducted an online cross-sectional survey in China between May and June 2024, recruiting 653 Chinese adults (mean age = 32.62 ± 7.40 years; 53.8% female) via Wenjuanxing. CCA was assessed using the CCAS. External variables included generalized anxiety (Chinese GAD-7), self-rated sleep quality (single-item, past week), and self-reported experience of meteorological disasters (yes/no). Latent profile analysis (LPA) and receiver operating characteristic (ROC) analyses were used to derive reference cutoff scores, and network analysis was applied to identify core items. LPA supported a two-profile solution and yielded an overall reference cutoff score of 27.5, above which participants were categorized as having elevated CCA risk. Participants classified as high risk reported higher generalized anxiety, poorer sleep quality, and a higher likelihood of meteorological disaster experience. Sex-stratified analyses indicated different optimal cutoffs: 28.5 for males (sensitivity = 1.000; specificity = 0.982) and 26.5 for females (sensitivity = 0.986; specificity = 0.986). Network analysis further suggested that the item Show less

Type 2 diabetes mellitus (T2DM) requires multi-target therapeutic approaches addressing both insulin resistance and insulin secretion deficits. Although natural compounds are promising multi-target candidates, systematic identification of their polypharmacological profiles remains challenging. The objective of this study was to establish a computational framework for identifying natural compounds with multi-target therapeutic potential against T2DM through integrated structure-activity analysis and experimental validation. We developed an SELFormer deep learning model to predict natural compound activities against six T2DM-related proteins including glucagon-like peptide-1 receptor (GLP1R), kinesin family member-11 (KIF11) for insulin secretion and insulin receptor (INSR), peroxisome proliferator-activated receptor-gamma (PPARG), fibroblast growth factor receptor-1 (FGFR1) and insulin-like growth factor-1 receptor (IGF1R) for insulin resistance. Uniform Manifold Approximation and Projection (UMAP) for dimension reduction clustering characterized chemical space distributions and molecular docking validated multi-target binding. Selected compounds were experimentally validated using 3T3-L1 adipocytes and mouse insulinoma (MIN6) pancreatic β-cells. The SELFormer model achieved Show less

Atherosclerosis is a chronic inflammatory disease marked by lipid accumulation and immune cell infiltration in arterial walls. Macrophages contribute by internalizing oxidized low-density lipoprotein, forming foam cells, and driving inflammation. The ubiquitin-proteasome system regulates immune and inflammatory responses in atherosclerosis. This study investigated the protective role of TRIM31 (tripartite motif-containing 31), an E3 ubiquitin ligase, in macrophage lipid metabolism and inflammation through selective regulation of LOX-1 (lectin-like oxidized low-density lipoprotein receptor-1). Transcriptomic profiling, macrophage-specific TRIM31 was selectively upregulated in macrophages under oxidized low-density lipoprotein stimulation and in atherosclerosis plaques. Trim31 deficiency exacerbated plaque burden, foam cell formation, and inflammatory signaling (n=8 per group). Single-cell analysis revealed enrichment of lipid transport and inflammatory pathways in Trim31-deficient plaques. LOX-1 was identified as a key TRIM31 substrate. TRIM31 promoted K48-linked ubiquitination of LOX-1 at lysine 12, facilitating its degradation. The atheroprotective effects of Trim31 were abolished in TRIM31, an inducible, macrophage-enriched protective factor in atherosclerosis, restricts foam cell formation and inflammation by targeting LOX-1 for proteasomal degradation. These findings position TRIM31 as a promising therapeutic target for macrophage-driven atherogenesis. Show less

Central pathophysiological mechanisms underlying cognitive impairment and mood disorders are complex. Traditional Chinese Medicine (TCM)-derived bioactive compounds have significant research value in this field. This study aimed to synthesize current preclinical and emerging clinical evidence on the neuroprotective and psychotropic effects of key TCM constituents, with a particular focus on their roles in modulating neuroinflammatory signalling, synaptic plasticity, oxidative balance and stress-related neuroendocrine pathways. A narrative synthesis of experimental and early clinical studies was conducted, emphasizing mechanistic investigations in rodent models and exploratory human trials. Outcomes of interest included inflammatory cytokine expression, inflammasome activation, redox homeostasis, synaptic signalling pathways, neuroendocrine regulation, behavioural performance and translational pharmaceutical considerations. Multiple TCM constituents attenuate microglial activation and inflammasome signalling, suppressing interleukin-1β, interleukin-6 and tumor necrosis factor-alpha through inhibition of nuclear factor κB and NOD-like receptor pyrin domain-containing 3 pathways. These effects restore redox homeostasis, reduce synaptic loss and improve cognitive and behavioural outcomes in animal models. Concurrently, several compounds enhance synaptic resilience by upregulating brain-derived neurotrophic factor and tropomyosin receptor kinase B signalling, activating downstream mechanistic target of rapamycin complex 1 and cyclic adenosine monophosphate response element-binding protein pathways and preserving synaptic proteins. Key agents, including ginsenosides, baicalin and curcumin, have shown translational promise, with small human trials reporting improvements in depressive symptoms, cognitive function and biomarker profiles. Additionally, TCM compounds modulate HPA axis dynamics by attenuating stress-induced corticosterone elevation, restoring glucocorticoid receptor sensitivity and rebalancing monoaminergic and glutamatergic neurotransmission. However, pharmaceutical translation remains limited by challenges related to formulation, dosage standardization and poor oral bioavailability, particularly for flavonoids and saponins. TCM-derived compounds exert multifaceted neuroprotective and psychotropic effects, while successful clinical translation requires strengthened pharmaceutical characterization, standardized dosing strategies and advanced delivery systems such as nanoformulations, phytosomes and standardized granules to enhance bioavailability, reliability and regulatory acceptance.
