To assess the predictive ability of baseline serum apolipoprotein B (ApoB) and the ratio of ApoB to apolipoprotein A1 (ApoB/ApoA1 ratio) for dyslipidemia risk in patients receiving second-generation antipsychotics (SGAs). Medical records of patients hospitalized between March 2019 and March 2025 were retrospectively reviewed. The optimal cut-off points for baseline serum ApoB levels and the ApoB/ApoA1 ratio were identified using a maximally selected log-rank statistic analysis. Multivariable Cox proportional hazards models estimated hazard ratios (HRs) with 95% confidence intervals (95% CIs). The Kaplan-Meier method with Log rank testing was used to compare the cumulative incidence of dyslipidemia between groups defined by these cut-off points. Of 311 enrolled patients, 33 (10.6%) lacking baseline ApoA1 measurements were excluded from ApoB/ApoA1 ratio analyses. The optimal cut-off points were 0.70 g/L for baseline ApoB and 0.45 for the ApoB/ApoA1 ratio. Multivariable Cox proportional hazards models, fully adjusted for covariates, demonstrated significantly elevated dyslipidemia risk for patients exceeding these thresholds vs low-risk groups: adjusted HR 2.98 (95% CI: 2.05-4.32, p < 0.001) for high ApoB and 3.17 (95% CI: 1.62-6.22, p = 0.001) for high ApoB/ApoA1 ratio. Continuous analysis showed each 0.1 g/L ApoB increase conferred a 34% higher risk (adjusted HR 1.34, 95% CI: 1.21-1.48, p < 0.001), while each 0.1-unit ApoB/ApoA1 ratio increase conferred a 20% higher risk (adjusted HR 1.20, 95% CI: 1.10-1.30, p < 0.001). Kaplan-Meier curves confirmed significantly higher cumulative dyslipidemia incidence in high vs low groups for both markers (Log rank test, both p < 0.001). Baseline serum ApoB levels and the ApoB/ApoA1 ratio are valuable risk markers for dyslipidemia in patients treated with SGAs. Show less

Atherosclerosis (AS) is a chronic inflammatory disorder characterized by foam cell formation and persistent inflammation as central pathological drivers. Although colchicine (Col) exhibits potent anti-inflammatory activities, its clinical application is limited by a narrow therapeutic window. In the present study, we developed phosphatidylserine-exposing nanovesicles (Col@PSVs) that leverage the innate phagocytic capacity of macrophage-derived foam cells by presenting surface "eat-me" signals, thereby enabling targeted immune modulation. The synergistic collaboration between Col and PSVs allows low-dose Col to retain robust anti-inflammatory efficacy while mitigating dose-dependent toxicity. Mechanistically, Col@PSVs potently suppress CCR7-mediated NF-κB signaling activation in foam cells, leading to a marked downregulation of pro-inflammatory cytokine and disruption of inflammatory cascades.

Brain metastasis occurs in up to 40% of patients with non-small cell lung cancer (NSCLC). Considerable genomic heterogeneity exists between the primary lung tumor and respective brain metastasis; however, the identity of the genes capable of driving brain metastasis is incompletely understood. Here, we carried out an in vivo genome-wide CRISPR activation screen to identify molecular drivers of brain metastasis from an orthotopic xenograft model derived from a patient with NSCLC. We found that activating expression of the Alzheimer's disease-associated beta-secretase 1 (BACE1) led to a substantial increase in brain metastases. Furthermore, genetic and pharmacological inhibition of BACE1 blocked NSCLC brain metastasis. Mechanistically, we identified that BACE1 acts through epidermal growth factor receptor to drive this metastatic phenotype. Together, our data highlight the power of in vivo CRISPR activation screening to unveil molecular drivers and potential therapeutic targets of NSCLC brain metastasis. Show less

Health literacy plays an important role in disease prevention and control. The aim of this study is to explore the health literacy patterns and associated factors among residents in Zhejiang Province. This study included 56,863 residents aged 15-69 years from the 2024 Zhejiang Province Health Literacy Survey. Latent Profile Analysis (LPA) was used to investigate health literacy patterns, and multinomial logistic regression analysis was employed to identify associated factors. Dominance analysis was performed to compare the relative contribution of the main variables associated with health literacy. The analysis identified three distinct health literacy profiles: low literacy (15.13%), moderate literacy (32.24%), and relatively high literacy (52.63%). The low literacy group was characterized by an older demographic (with an average age of 58.71 years), lower educational attainment (20.72% had no formal education), a higher proportion of farmers (52.93%), and a significant share of low-income individuals (40.98%). Multinomial logistic regression and dominance analysis revealed that education level, age, and occupation were the most important associated factors of health literacy. The study findings highlighted the heterogeneity in health literacy among various population groups and emphasized the need for targeted interventions. This study provides empirical evidence to inform precision health promotion strategies in developed regions of China. Show less

To explore the correlation between different traditional Chinese medicine (TCM) constitution types and apolipoprotein B (ApoB) in patients with hyperuricemia (HUA) and to investigate the relationships between TCM constitutions, uric acid levels, and various cardiovascular risk factors. A cross-sectional study involving 683 patients diagnosed with HUA was conducted. Patients' TCM constitutions were classified using the standardise "Classification and Determination of TCM Constitution" questionnaire. Serum uric acid (UA), lipid profiles, ApoB, and homocysteine (Hcy) levels were measured. Among 683 HUA patients, phlegm-dampness (22.99% ) and damp-heat constitution (20.06% ) were the most common TCM constitution types. UA, ApoB, and Hcy levels in patients with phlegm-damp constitution were significantly higher than those in other constitutions (P< 0.05). UA levels were negatively correlated with HDL-C (r=-0.472, P= 0.027) and positively correlated with ApoB (r= 0.618, P= 0.012) and Hcy (r= 0.492, P= 0.018). Phlegm-damp and damp-heat constitutions are the most common TCM constitution types in HUA patients and are associated with higher levels of UA, ApoB, and Hcy. These constitutional types are independently associated with increased cardiovascular risk. Show less

SIRT4 is a member of the sirtuin family, which is related to mitochondrial function and possesses antioxidant and regulatory redox effects. Currently, the roles of SIRT4 in retinal Müller glial cells, oxidative stress, and mitochondrial function are still unclear. We confirmed, by immunofluorescence staining, that SIRT4 is located mainly in the mitochondria of retinal Müller glial cells. Using flow cytometry and Western blotting, we analyzed cell apoptosis, intracellular reactive oxygen species (ROS) levels, apoptotic and proapoptotic proteins, mitochondrial dynamics-related proteins, and mitochondrial morphology and number after the overexpression and downregulation of SIRT4 in rMC-1 cells. Neither the upregulation nor the downregulation of SIRT4 alone affected apoptosis. SIRT4 overexpression reduced intracellular ROS, reduced the BAX/BCL2 protein ratio, and increased the L-OPA/S-OPA1 ratio and the levels of the mitochondrial fusion protein MFN2 and the mitochondrial cleavage protein FIS1, increasing mitochondrial fusion. SIRT4 downregulation had the opposite effect. Mitochondria tend to divide after serum starvation for 24 h, and SIRT4 downregulation increases mitochondrial fragmentation and oxidative stress, leading to aggravated cell damage. The mitochondrial division inhibitor Mdivi-1 reduced oxidative stress levels and thus reduced cell damage caused by serum starvation. The overexpression of SIRT4 in rMC-1 cells reduced mitochondrial fragmentation caused by serum starvation, leading to mitochondrial fusion and reduced expression of cleaved caspase-3, thus alleviating the cellular damage caused by oxidative stress. Thus, we speculate that SIRT4 may protect retinal Müller glial cells against apoptosis by mediating mitochondrial dynamics and oxidative stress. Show less

Alzheimer's disease (AD) is an irreversible age-related neurodegenerative condition characterized by the deposition of amyloid-β (Aβ) peptides and neurofibrillary tangles. Di Huang Yi Zhi (DHYZ) formula, a traditional Chinese herbal compound comprising several prescriptions, demonstrates properties that improve cognitive abilities in clinical. Nonetheless, its molecular mechanisms on treating AD through improving neuron cells mitochondria function have not been deeply investigated. This study administered DHYZ to APP/PS1 mice to explore its potential therapeutic mechanisms in AD treatment. APP/PS1 transgenic mice were given DHYZ (L, M, H), donepezil, or distilled water for a consecutive 12-week period. The Morris water maze test was used to assess memory capacity, transmission electron microscopy was used to observe mitochondrial and synaptic structures, immunohistochemistry and western blot detected proteins involved in the mitochondrial autophagy pathway, ELISA measured serum Aβ content, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assessed neuronal cell apoptosis. DHYZ demonstrates a notable therapeutic impact on mice with AD, effectively improving cognitive and memory impairments. DHYZ decreases Aβ accumulation in the hippocampus by reducing BACE1 activity and enhancing Aβ clearance through the blood-brain barrier. Additionally, DHYZ significantly suppresses neuronal apoptosis, enhances synaptic structure, and increases synapse numbers, processes strongly linked to the activation of mitochondrial PINK1-Parkin autophagy. DHYZ enhances cognitive function in APP/PS1 mice by stimulating neuronal mitochondrial autophagy through the PINK1-Parkin pathway. Show less

Microplastics intrigue kidney toxicity such as mitochondrial dysfunction and inflammation promotion. However, as an organ relying heavily on fatty acid oxidation, how microplastics influence kidney lipidomes remain unclear. Hence, we performed Raman spectra and multidimensional mass spectrometry-based shotgun lipidomics to decode kidney lipidomics landscape under polypropylene microplastics exposure. Kidney functions and cellular redox homeostasis were remarkably disturbed as revealed by levels of biochemical renal function markers, malonaldehyde, hydrogen peroxide and antioxidants. Ultrastructure alterations including the foot process fusion implied the kidney injury associated with lipidomic changes. Raman spectra successfully further confirmed the cellular change of reactive oxygen species and lipid disorders. Lipidomics showed that polypropylene microplastics caused abnormal lipidome and irregular exchange by remodeling triglycerides and phospholipids. Genes involved in lipid metabolism such as Fads1 and Elovl5 exhibited highly diversified expression profiles responding to polypropylene microplastics stress and possessed significant correlations with ROS indicators. These results explained ultrastructure alterations and aggravation of kidney injuries. Our work revealed polypropylene microplastics inducing lipidomic detriment in mouse kidney by Raman spectra and lipidomics firstly, elucidating the significances of lipidomic remodeling coupled with ROS stress in the kidney damages. The findings provided reliable evidence on the health risks of polypropylene microplastics in kidney. Show less

The middle temporal gyrus region of the brain is susceptible to pronounced impairment in Alzheimer's disease. Identification of the molecules involved in vascular aberrance of the middle temporal gyrus would support elucidation of the mechanisms underlying Alzheimer's disease and discovery of novel targets for intervention. We carried out single-cell transcriptomic analysis of the middle temporal gyrus in the brains of patients with Alzheimer's disease and healthy controls, revealing obvious changes in vascular function. CellChat analysis of intercellular communication in the middle temporal gyrus showed that the number of cell interactions in this region was decreased in Alzheimer's disease patients, with altered intercellular communication of endothelial cells and pericytes being the most prominent. Differentially expressed genes were also identified. Using the CellChat results, AUCell evaluation of the pathway activity of specific cells showed that the obvious changes in vascular function in the middle temporal gyrus in Alzheimer's disease were directly related to changes in the vascular endothelial growth factor (VEGF)A-VEGF receptor (VEGFR) 2 pathway. AUCell analysis identified subtypes of endothelial cells and pericytes directly related to VEGFA-VEGFR2 pathway activity. Two subtypes of middle temporal gyrus cells showed significant alteration in AD: endothelial cells with high expression of Erb-B2 receptor tyrosine kinase 4 (ERBB4 high ) and pericytes with high expression of angiopoietin-like 4 (ANGPTL4 high ). Finally, combining bulk RNA sequencing data and two machine learning algorithms (least absolute shrinkage and selection operator and random forest), four characteristic Alzheimer's disease feature genes were identified: somatostatin ( SST ), protein tyrosine phosphatase non-receptor type 3 ( PTPN3 ), glutinase ( GL3 ), and tropomyosin 3 ( PTM3 ). These genes were downregulated in the middle temporal gyrus of patients with Alzheimer's disease and may be used to target the VEGF pathway. Alzheimer's disease mouse models demonstrated consistent altered expression of these genes in the middle temporal gyrus. In conclusion, this study detected changes in intercellular communication between endothelial cells and pericytes in the middle temporal gyrus and identified four novel feature genes related to middle temporal gyrus and vascular functioning in patients with Alzheimer's disease. These findings contribute to a deeper understanding of the molecular mechanisms underlying Alzheimer's disease and present novel treatment targets. Show less

Conjugated linoleic acid (CLA) isomers have been reported to reduce body weight and promote glycolipid metabolism in animals. In a preliminary study, we revealed that trans-10, cis-12-CLA (10,12-CLA) plays an important role in modulating lipid metabolism in chickens. However, the underlying mechanism remains unclear. In this study, we constructed an isolated in vitro model with primary chicken hepatocytes to investigate the effect of 10,12-CLA on lipid metabolism. 10,12-CLA inhibited lipid accumulation by decreasing the mRNA expression of sterol regulatory element-binding protein-1c (SREBP-1c), SREBP2, 3‑hydroxy-3-methylglutaryl-CoA reductase (HMGCR), fatty acid synthase (FAS), adipose triacylglyceride lipase (ACC), and lipoprotein lipase (LPL) and increasing the mRNA expression of peroxisome proliferator-activated receptor α (PPARα), carnitine palmitoyltransferase 1 (CPT1) and adipose triacylglyceride lipase (ATGL). Furthermore, 10,12-CLA treatment activated the protein expression of extracellular signal-regulated kinase 1/2 (ERK1/2) and AMP-activated protein kinase (AMPK), whereas treatment with the ERK1/2 inhibitor U0126 reversed the inhibitory effects of 10,12-CLA on lipid accumulation by blocking the ERK1/2-AMPK pathway, leading to increased lipid accumulation and triglyceride content in primary chicken hepatocytes. These findings suggest that in chicken hepatocytes, 10,12-CLA alleviates hepatocyte lipid deposition by activating the ERK1/2-AMPK pathway, promoting fatty acid oxidation and reducing lipid synthesis, revealing the potential mechanism through which 10,12-CLA regulates hepatic lipid metabolism in chickens.

Accumulating evidence has demonstrated that nucleic acid-based therapies are promising for atherosclerosis. However, nearly all nucleic acid delivery systems developed for atherosclerosis necessitate injection, which results in rapid elimination and poor patient compliance. Consequently, oral delivery strategies capable of targeting atherosclerotic plaques are imperative for nucleic acid therapeutics. Herein we report the development of yeast-derived capsules (YCs) packaging an antisense oligonucleotide (AM33) targeting microRNA-33 (miR-33) for the oral treatment of atherosclerosis. YCs provide stability for AM33, preventing its premature release in the gastrointestinal tract. AM33-containing YCs, defined as YAM33, showed high transfection in macrophages, thus promoting cholesterol efflux and inhibiting foam cell formation by regulating the target genes/proteins of miR-33.

Energy deprivation and metabolic rewiring of cardiomyocytes are widely recognized hallmarks of heart failure. Here, we report that HEY2 (a Hairy/Enhancer-of-split-related transcriptional repressor) is upregulated in hearts of patients with dilated cardiomyopathy. Induced Hey2 expression in zebrafish hearts or mammalian cardiomyocytes impairs mitochondrial respiration, accompanied by elevated ROS, resulting in cardiomyocyte apoptosis and heart failure. Conversely, Hey2 depletion in adult mouse hearts and zebrafish enhances the expression of mitochondrial oxidation genes and cardiac function. Multifaceted genome-wide analyses reveal that HEY2 enriches at the promoters of genes known to regulate metabolism (including Ppargc1, Esrra and Cpt1) and colocalizes with HDAC1 to effectuate histone deacetylation and transcriptional repression. Consequently, restoration of PPARGC1A/ESRRA in Hey2- overexpressing zebrafish hearts or human cardiomyocyte-like cells rescues deficits in mitochondrial bioenergetics. Knockdown of Hey2 in adult mouse hearts protects against doxorubicin-induced cardiac dysfunction. These studies reveal an evolutionarily conserved HEY2/HDAC1-Ppargc1/Cpt transcriptional module that controls energy metabolism to preserve cardiac function. Show less

Cardiovascular-Kidney-Metabolic (CKM) syndrome is characterized by the interrelatedness of chronic kidney disease, cardiovascular disease, and metabolic disorders. Although physical activity is widely acknowledged as an effective intervention for improving the prognosis of chronic diseases, its impact on all-cause mortality among patients with CKM syndrome remains unclear. To investigate the impact of physical activity on all-cause mortality among patients with CKM syndrome. Data from the 2011 wave of the China Health and Retirement Longitudinal Study were used as the baseline, with follow-up conducted until 2013. According to the International Physical Activity Questionnaire criteria, weekly physical activity levels were divided into three categories: light-volume physical activity (LPA), moderate-volume physical activity (MPA), and vigorous-volume physical activity (VPA). Cox proportional hazards regression models were employed to assess the impact of varying levels of physical activity on all-cause mortality. Restricted cubic spline analysis was used to explore possible nonlinear relationships. A total of 3343 patients with CKM syndrome were enrolled in this study. During the 2-year follow-up period, 44 deaths were recorded. After adjusting for potential confounders, VPA was associated with a 54% lower risk of all-cause mortality (adjusted hazard ratios, 0.46; 95% confidence interval: 0.24-0.89). Dose-response relationships demonstrated that all-cause mortality decreased as physical activity increased, with a 5.8% reduction in all-cause mortality risk for every 1000 MET-min/week increment in physical activity levels. VPA was significantly associated with reduced all-cause mortality in patients with CKM syndrome. Encouraging patients with CKM syndrome to engage in increased physical activity may improve clinical outcomes. Key messages What is already known on this topic: Cardiovascular-Kidney-Metabolic (CKM) syndrome involves a complex interplay between cardiovascular disease, metabolic disorders, and chronic kidney disease. While prior studies have established that physical activity can decrease mortality risk in the general population as well as in patients with cardiovascular and metabolic syndromes, the evidence regarding its impact on individuals with CKM syndrome remains limited. Additionally, there is a lack of detailed dose-response analyses of physical activity specifically targeting this high-risk population. What this study adds: This study provides novel evidence indicating that vigorous-volume physical activity (>3000 MET-minutes/week) significantly decreases all-cause mortality by 54% among patients with CKM syndrome, whereas moderate-volume, and light-volume physical activities show no significant effects. Notably, a linear dose-response relationship was established, demonstrating that each 1000-MET increment corresponds to a 5.8% reduction in mortality risk. These findings address a critical knowledge gap by quantifying both the threshold and incremental benefits of physical activity specifically for individuals with CKM syndrome, a population characterized by unique multisystem pathophysiology. How this study might affect research, practice, or policy: The findings of this study have the potential to substantially impact clinical practice by offering evidence-based thresholds for physical activity recommendations in the management of CKM syndrome. The benefits associated with vigorous-volume physical activity (>3000 MET-minutes/week) may encourage guideline committees to formulate more precise exercise prescriptions tailored to this high-risk population. Additionally, these results can be incorporated into a multidisciplinary care framework designed for managing complex chronic conditions. Show less

Highly effective therapies to reduce triglyceride levels are lacking. Olezarsen is an In this phase 3, international, double-blind, randomized, placebo-controlled trial, we enrolled patients with moderate hypertriglyceridemia (triglyceride level, 150 to 499 mg per deciliter) and elevated cardiovascular risk or with severe hypertriglyceridemia (triglyceride level, ≥500 mg per deciliter) and randomly assigned them in a 1:3 ratio to a 50-mg or 80-mg cohort. The patients were then randomly assigned in a 3:1 ratio to receive monthly subcutaneous olezarsen or matching placebo within each cohort. The primary outcome was the least-squares mean percent change in triglyceride level from baseline to 6 months among the patients with moderate hypertriglyceridemia, reported as the difference between each olezarsen dose group and the placebo group (the placebo-adjusted change). A total of 1349 patients (254 in the olezarsen 50-mg group, 766 in the olezarsen 80-mg group, and 329 in the placebo group) were included in the primary efficacy analysis. The median age was 64 years, 40% of the patients were women, and the median triglyceride level at baseline was 238.5 mg per deciliter (interquartile range, 190.5 to 307.5). At 6 months, the placebo-adjusted least-squares mean change in triglyceride level was -58.4 percentage points (95% confidence interval [CI], -65.1 to -51.7; P<0.001) in the olezarsen 50-mg group and -60.6 percentage points (95% CI, -67.1 to -54.0; P<0.001) in the olezarsen 80-mg group. The incidence of serious adverse events appeared to be similar across the trial groups. Among patients with moderate hypertriglyceridemia and elevated cardiovascular risk, treatment with olezarsen resulted in significantly greater reduction in triglyceride levels at 6 months than placebo.

Pediatric primary cardiomyopathies (PCMs) are rare diseases with complex causes and nonspecific treatment. The influence of electrolytes and amino acids (AAs) on cardiomyopathies has not been extensively studied. This study aimed to explore clinical characteristics and the usage of electrolytes and AAs in children with PCMs. Children diagnosed with PCMs who had genetic test reports were included. Relevant information was collected and processed, and clinical characteristics and mutated genes were clarified. Gene databases were searched to explore related electrolytes and AAs in the treatment of PCMs. The effect of calcium was explored in children with DCM. Paired samples T tests and nonparametric Wilcoxon signed-rank tests were performed for comparison between before and after using calcium. In this study, 27 children with gene test results were enrolled to perform gene-related analysis. The median age was 2.5 years old. Mutated genes were collected, including pathogenic, likely pathogenic, uncertain significance, and other mutations. The most frequently mutated genes related to dilated cardiomyopathy (DCM) were For children with DCM, calcium supplements may be beneficial. AAs, including serine, cysteine, and arginine, could be used for supplementary treatment in children with DCM and HCM. Show less

Angiopoietin-like proteins (ANGPTLs) represent a family of secreted glycoproteins that are extensively expressed in vivo and are integral to various pathophysiological processes, including glucose and lipid metabolism, stem cell proliferation, local inflammation, vascular permeability, and angiogenesis. Particularly interesting is ANGPTL4, which has been identified as a significant factor in the development and progression of diabetic retinopathy (DR), thus becoming a central focus of DR research. ANGPTLs modulate metabolic pathways, enhance vascular permeability, and facilitate pathological angiogenesis, in addition to causing intraocular inflammation. As promising molecular targets, ANGPTLs not only serve as biomarkers for predicting the onset and progression of DR but also present therapeutic potential through antibody-based interventions. This paper discusses the pathogenesis of DR and the potential applications of ANGPTLs in early diagnosis and targeted therapy. It provides references for advancing precision diagnosis and personalized treatment strategies through more profound ANGPTLs research in the future. Show less

The aim of this review is to systematically explore the critical role of dual-specific phosphatases (DUSPs) in CKD-associated cognitive impairment and their therapeutic potential. Chronic kidney disease (CKD) is a global health burden, and the cognitive impairment it induces seriously affects patients' quality of life. Studies have shown that DUSPs are involved in pathological processes such as inflammation, oxidative stress, fibrosis, and neuronal apoptosis through the regulation of signaling pathways such as MAPK, which in turn affects the cognitive function of CKD patients. Specifically, downregulation of DUSP1 and DUSP6 expression in brain tissues of CKD patients is associated with cognitive impairment, whereas upregulation of DUSP8 and DUSP16 exacerbates cognitive deficits by promoting neuroinflammation. In addition, uremic toxins (e.g., indolephenol sulfate) can further deteriorate cognitive function by altering the activity of DUSPs and interfering with central nervous system signaling. Although there are currently no clinical drugs targeting DUSPs, small molecule inhibitors, gene modulation techniques, and natural compounds have demonstrated the potential to improve cognitive function by modulating DUSPs. Future studies need to focus on optimizing the specificity and selectivity of DUSPs inhibitors and conducting rigorous clinical validation. In-depth elucidation of the mechanism of action of DUSPs in the renal-brain axis will provide an important theoretical basis for the development of novel intervention strategies for CKD-associated cognitive impairment.

Polycystic ovary syndrome (PCOS) is frequently accompanied with metabolic dysfunctions, yet the causal relationships between metabolic factors and PCOS remain to be conclusively established and etiology-based therapies are lacking. To comprehensively identify the metabolic causal factors and potential drug targets for PCOS. This genetic association study was conducted using bidirectional two-sample Mendelian Randomization (MR), multivariable MR (MVMR) and drug-target MR. Considering metabolic sexual dimorphism, female-specific genome-wide association studies (GWASs) for metabolic factors were obtained. To ensure the robustness of the findings, an additional independent PCOS GWAS dataset was utilized for replication. The PCOS cohort included 10,074 PCOS cases (mean age 28 to 45 years) and 103,164 controls (mean age 27 to 60 years) of European ancestry. All participants were female. Employing two-sample MR analysis, we found that genetically proxied body mass index (BMI) (OR = 3.40 [95 % CI, 2.65-4.36]), triglyceride (TG) (OR = 1.54 [95 % CI, 1.17-2.04]), low-density lipoprotein cholesterol (LDL-c) (OR = 1.37 [95 % CI, 1.07-1.76]), and type 2 diabetes (T2D) (OR = 1.24 [95 % CI, 1.09-1.41]) were significantly associated with an increased risk of PCOS, whereas genetically predicted high-density lipoprotein cholesterol (HDL-c) (OR = 0.61 [95 % CI, 0.47-0.80]) decreased the odds of PCOS. Stepwise MVMR established a hierarchy of interactions among these metabolic factors, identifying BMI and HDL-c as the most prominent causal factors. Notably, drug-target MR analysis identified incretin-based therapeutics, PCSK9 inhibitors, LPL gene therapy, sulfonylureas, and thiazolidinediones as potential therapeutics for PCOS. All these findings were validated in an independent dataset. This study offered insights into the roles of obesity, diabetes, and dyslipidemia in PCOS etiology and therapeutics, underscoring the necessity for managing metabolic health in women and paving the way for tailored therapeutic strategies for PCOS based on its metabolic underpinnings.

This study aims to evaluate the impact of prepregnancy glucagon-like peptide-1 receptor agonist (GLP-1RA) use on lipid metabolism during pregnancy. A retrospective case-control study with 42 participants was employed to analyze the impact of prepregnancy GLP-1RA use on lipid metabolism during pregnancy in women with obesity. An animal study involved 60 virgin female Sprague Dawley rats fed a normal diet or a high-fat diet (HFD) for 8 weeks, with the latter diet divided into HFD + saline, HFD + liraglutide, and HFD + semaglutide for 4 weeks. Rats were mated and then sacrificed on gestational day 21. Clinically, prepregnancy GLP-1RA use reduced prepregnancy BMI, gestational weight gain, ratio with first-trimester metabolic dysfunction-associated steatotic liver disease, and triglyceride levels during pregnancy. In animals, GLP-1RA improved plasma fibroblast growth factor 21 (FGF21), adiponectin, triglyceride levels, and leptin in midgestation. During late gestation, compared with the HFD group, the GLP-1RA groups exhibited improved liver lipid deposition, increased fatty acid oxidation and lipolysis genes, decreased lipogenesis genes, and increased extracellular signal-regulated kinase (ERK)/peroxisome proliferator-activated receptor γ (PPAR-γ) and AMP-activated protein kinase (AMPK)/NAD-dependent protein deacetylase sirtuin-1 (SIRT1) pathways in liver; in the visceral adipose, the GLP-1RA groups showed increased lipolysis genes, decreased lipogenesis genes, and increased phosphorylated to total fibroblast growth factor receptor 1 (FGFR1) with activated ERK/PPAR-γ pathways. Prepregnancy GLP-1RA use improves maternal lipid metabolism during pregnancy, potentially involving elevated liver-secreted FGF21. This study offers a new strategy for treating lipid metabolic disorders in pregnancy. Show less

To identify distinct sleep quality profiles among patients undergoing maintenance hemodialysis (MHD) using latent profile analysis (LPA), and examine differences in perceived stigma across these sleep quality subtypes. From December 2024 to March 2025, a total of 334 MHD patients were recruited via convenience sampling from the nephrology departments of two tertiary hospitals in Xinjiang, China. Data were collected using structured questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), the Self-Rating Depression Scale (SDS), and the Social Impact Scale (SIS), along with sociodemographic and clinical information. LPA was employed to identify latent subgroups of sleep quality based on PSQI components. Multinomial logistic regression was used to determine predictors of sleep profile membership. Differences in stigma scores across sleep profiles were analyzed using non-parametric equivalents. Three distinct sleep profiles were identified: Class 1 - "overall better sleep", Class 2 - "short sleep duration and low efficiency", and Class 3 - "poor sleep quality with high medication use". Multinomial logistic regression identified comorbid heart failure (OR=2.867, Patients with MHD exhibit heterogeneous patterns of sleep disturbance, which are associated with varying levels of perceived stigma. Those with the poorest sleep quality and highest reliance on medication experience the most pronounced stigma. Tailored interventions addressing sleep-related issues and psychosocial factors may help reduce stigma and improve patient well-being. Show less

Gastrointestinal (GI) cancers exhibit aberrant lipid metabolism, yet the causal mechanisms remain elusive. Here, we integrated Mendelian randomization (MR) and multi-omics data to dissect metabolic drivers of 20 GI diseases. Focusing on colorectal (CC) and esophageal cancer (EC), we identified five metabolites (e.g., 1,2-di-palmitoyl-sn-glycero-3-phosphocholine) and arachidonic acid ethyl ester as causal drivers. Summary-data-based MR and colocalization analysis (PP.H4 > 0.75) revealed FADS1 as a master regulator of these metabolites, with genetic variants exhibiting tissue-specific lipidomic effects. Functional validation using FADS1-knockout cell lines and mouse models demonstrated that FADS1 inhibition suppresses tumor cell proliferation, migration, and invasion while promoting apoptosis. In vivo, FADS1 deletion reduced chemically induced CC/EC tumor burden by 62-75%, accompanied by decreased Ki-67/MMP-9 expression and inflammatory infiltration. Mechanistically, FADS1 ablation disrupted lipid metabolism (reduced linoleic acid and arachidonic acid) and attenuated PI3K/AKT and MAPK signaling. Multi-omics integration further corroborated FADS1-mediated epigenetic regulation (e.g., mQTL-driven DNA methylation). This study establishes FADS1 as a pivotal orchestrator of GI carcinogenesis via metabolic reprogramming and signaling dysregulation, offering a compelling therapeutic target for precision oncology in CC and EC.

In recent years, there has been a steady increase in professionals engaged in radioactive work. The biological impacts of long-term exposure to low dose-rate radiation remain elusive, as there is a dearth of systematic research in this field. BEAS-2B cells were used to establish a cell model with continuous passaging after radiation exposure, which was subsequently subjected to in vivo tumorigenesis assays and in vitro malignant phenotype experiments. By scRNA-seq, we conducted copy number variation analysis, cell trajectory analysis, and cell communication analysis. Furthermore, we used FACS, molecular docking, multiplex immunohistochemistry, qRT-PCR, and co-immunoprecipitation to validate and further explore the molecular mechanisms driving tumor evolution. Long-term low dose-rate exposure is associated with a higher degree of malignancy, as evidenced by the induction of more CNV and EMT events, as well as the delayed activation of DNA repair pathways, which trigger increased genomic instability. The long-term low dose-rate specific ligand-receptor pair, ANGPTL4-SDC4, enhances cell malignancy by promoting angiogenesis in newly formed lung tumor cells. This study not only provides the first evidence and mechanistic explanation that long-term low dose-rate radiation leads to increased cellular malignancy but also offers valuable theoretical insights into the dynamic processes of early tumor evolution in lung cancer within the realm of tumor biology.

Triglyceride-rich lipoproteins carry lipids in the bloodstream, where the fatty acid moieties are liberated by lipoprotein lipase (LPL) and taken up by peripheral tissues such as brown adipose tissue (BAT) and white adipose tissue (WAT), whereas the remaining cholesterol-rich remnant particles are cleared mainly by the liver. Elevated triglyceride (TG) levels and prolonged circulation of cholesterol-rich remnants are risk factors for cardiovascular diseases. Acute cold exposure decreases postprandial TG levels and is a potential therapeutic approach to treat hypertriglyceridemia. However, how acute cold exposure regulates TG metabolism remains incompletely understood. In the current study, we found that acute cold exposure simultaneously increases postprandial very-low-density lipoprotein production and TG clearance, with the latter playing a dominant role and resulting in decreased TG levels. Acute cold exposure increases LPL activity and TG uptake in BAT, while suppressing LPL activity and TG uptake in WAT. Mechanistically, acute cold exposure increases BAT LPL activity through transcriptional upregulation of Lpl and posttranscriptional regulation via inhibiting the hepatic insulin-ANGPTL8-ANGPTL3 axis, while suppressing WAT LPL activity through upregulation of ANGPTL4. Angptl8 knockout mice have dramatically decreased levels of circulating TG. In the absence of ANGPTL8, acute cold exposure increases rather than decreases circulating TG levels. Thus, our study reveals multilayered regulation of acute cold response and postprandial TG metabolism, highlighting the key functions of ANGPTL3, 4, and 8 in response to acute cold exposure.

Coelonin is a dihydrophenanthrene compound derived from the traditional Chinese medicine Bletilla striata (Thunb.) Reichb.f., which exhibits significant anti-inflammatory activity and effectively inhibits lipopolysaccharide (LPS)-induced inflammatory responses in RAW264.7 cells. Although previous studies have demonstrated the protective effect of Bletilla striata against LPS-induced acute lung injury (ALI), the potential protective role and underlying molecular mechanisms of its major active component, Coelonin, in ALI remain unclear. In this study, an LPS-induced mouse ALI model was established to systematically evaluate the protective effects of Coelonin on ALI. Furthermore, transcriptomic analysis was utilized to investigate the anti-inflammatory mechanisms mediated by Coelonin through the regulation of non-coding RNA (ncRNA)-associated inflammatory pathways. The results indicated that Coelonin significantly ameliorated LPS-induced pathological damage in lung tissues and markedly reduced the levels of inflammatory markers in bronchoalveolar lavage fluid (BALF). In vitro experiments using the murine alveolar macrophages (MH-S) cell line further confirmed the anti-inflammatory activity of Coelonin. Transcriptome analysis revealed that Coelonin markedly upregulates the expression of the ncRNA Gm27505, which was previously found to be downregulated in a mouse model of Alzheimer's disease. To date, there have been no reports on the biological functions of Gm27505. Bioinformatics analysis and real-time quantitative fluorescence PCR (qPCR) confirmed that this ncRNA is primarily localized within the nucleus. Overexpression of Gm27505 in MH-S cells significantly downregulated the expression of inflammation-related genes such as Il6, Tnfα, Il27, and Ccl3 induced by LPS stimulation. Moreover, overexpression of Gm27505 promoted macrophage polarization toward the M2 phenotype while suppressing M1 polarization. These findings suggest that the ncRNA Gm27505 plays an important biological role and is critically involved in the regulation of inflammatory responses. Coelonin may alleviate LPS-induced ALI in mice by up-regulating Gm27505 expression and modulating macrophage polarization. Therefore, Gm27505 may represent a potential target for the prevention and treatment of ALI, providing new research directions for future therapeutic strategies against related diseases. Show less
