Biomolecular condensates, membrane-less assemblies formed by phase separation, are implicated in neurodegenerative disease, but their role in Alzheimer's disease (AD) remains unclear. Here, we report that in the brain of AD patients and animal models, an elevation of poly(C)-binding protein 2 (PCBP2) correlates with biomolecular condensation that involves phase separation. These condensates sequester large numbers of mitochondrial and mRNA-binding proteins, leading to the outside impairment of mitochondrial morphology and function, and BACE1 mRNA decay relative to amyloid deposition. We then identify a small molecule CN-0928 that inhibits the condensates by reducing PCBP2 protein level and mitigates AD pathology and cognitive decline, in which CN-0928 binding to a target protein integrator complex subunit 1 (INTS1) allows to regulate PCBP2 expression. Our findings place PCBP2 condensates as a key player that cooperates the seemingly disparate but important pathways, and show pharmacological modulation of PCBP2 as an effective approach for treating AD.

Symptom burden in primary brain tumor patients varies, emphasizing the need for comprehensive understanding to improve patient care. This study aims to identify distinct symptom clusters among brain tumor patients in Shanghai, China, using Latent Profile Analysis (LPA) to guide personalized diagnosis, treatment, and supportive care. A longitudinal study was conducted among 161 patients with primary brain tumors in Shanghai. Participants completed the MD Anderson Symptom Inventory Brain Tumor Module (MDASI-BT) at three intervals: the day of admission (T1), three days after surgery (T2), and two weeks after surgery (T3). Latent Profile Analysis (LPA) was used to identify subgroups with unique symptom patterns. Six distinct subgroups were identified (entropy = 0.964), ranging from low-burden to persistently severe patterns. Subgroup membership was partially associated with age, tumor grade, and diagnosis. These subgroups were: transient postoperative burden group, stable symptom with cognitive emergence group, distress-predominant, low burden group, elderly-high grade, persistently severe group, nausea-dominant recovery group, and distress-plus-nausea, younger urban group. Our findings reveal substantial heterogeneity in perioperative symptom experiences among brain tumor patients. Identifying subgroups with high and persistent symptom burden may help clinicians target interventions such as enhanced education, proactive monitoring, rehabilitation, psychological support, and antiemetic management. This subgroup-based approach may improve quality of life, reduce morbidity, and guide precision supportive care in neuro-oncology. Show less

The competency of specialist nurse clinical educators is crucial for the effectiveness of specialist nurse training programmes. However, variability in teaching competency and training needs among educators remains insufficiently studied, especially in the context of rapidly evolving healthcare education in China. This study aimed to identify distinct core competency profiles among clinical educators for specialist nurses, examine associated socio-demographic factors, and explore differences in training needs across profiles. A cross-sectional online survey was conducted with 3,945 specialist nurse clinical educators from 30 Chinese regions. The Chinese version of the Nurse Educator Core Competency Scale (NECCS) and a self-developed training needs questionnaire were used. Latent Profile Analysis (LPA) identified competency subgroups, while multinomial logistic regression and Kruskal-Wallis tests examined associated variables and training needs. Latent Profile Analysis identified three competency profiles: foundational (8.6%), intermediate (43.0%), and advanced (48.4%), with mean scores of 43.89, 68.24, and 91.68, respectively. Educators without prior training were significantly more likely to belong to the foundational (OR = 3.195, p < 0.001) and intermediate (OR = 1.676, p < 0.001) groups compared to those with training experience. Advanced-competency educators showed the highest demand for curriculum design training, with 75% rating it as highly necessary. In contrast, educators in the intermediate group identified clinical teaching methods and techniques as their top training need (58.7%). Those in the foundational group prioritised common pedagogical methods and instructional technologies (54.7%). Clinical educator competencies vary by background characteristics and training exposure. Tailored, competency-based training is needed to address these gaps and enhance the quality of specialist nursing education. Show less

However, the role of HDAC3 in mediating epigenetic modifications and regulating endothelial inflammation in atherosclerosis remains unclear. This study aims to investigate the impact of HDAC3 on endothelial inflammation and its contribution to atherosclerosis. Firstly, single-cell transcriptomic analysis identified elevated expression of HDAC3 and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) in inflammatory endothelial cells of atherosclerotic plaques in symptomatic patients.

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

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

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

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.

This study aims to investigate the spectrum and prognosis of membranous nephropathy (MN) in patients with Sjögren's syndrome (SS). SS patients with biopsy-proven kidney involvement who were diagnosed at our center between April 2007 and February 2024 were retrospectively reviewed and analyzed. A total of 290 SS patients with kidney involvement were enrolled. The frequency of MN increased from 16.28% during the 2007-2010 period to 44.05% during the 2021-2024 period. After 2016, MN became the most common renal pathologic type, surpassing tubulointerstitial nephritis. PLA2R antibody or antigen was detected in 74 SS-MN patients, in whom 37 (50%) showed a negative result. Within the PLA2R-negative group, five out of 15 showed positivity for EXT1/EXT2 antigen and one out of eight for THSD7A antigen. Sixty-one SS patients with MN were followed up for >6 months, and 44 (72.13%) of them achieved renal complete remission (CR). Compared with PLA2R-negative patients, PLA2R-positive patients spent a longer time to achieve CR (1.46 ± 1.16 vs. 0.74 ± 0.47 years, MN has become the predominant renal pathologic type in SS. PLA2R-positivity testing followed by EXT1/EXT2 and THSD7A testing is recommended for SS-MN patients. Although most patients can achieve renal CR, the prognosis is usually poor in PLA2R-positive SS-MN patients. 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

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

The aim of this study was to investigate the ameliorative effects of pterostilbene (PTE), a polyphenolic compound, on stress-induced lipid metabolic disorders in the liver of broiler chickens. Six hundred healthy, 1-day-old Arbor Acres with similar weight were randomly assigned to five groups, each consisting of eight replicates with 15 broilers per replicate. The groups included: a control group (fed a basal diet), and four groups treated with corticosterone (CORT) at varying dietary levels of PTE supplementation: CORT (0 mg/kg PTE), CORT-PT200 (200 mg/kg PTE), CORT-PT400 (400 mg/kg PTE), and CORT-PT600 (600 mg/kg PTE). The results indicated that PTE administration to corticosterone (CORT)-injected broilers significantly improved weight gain, reduced liver index, and lowered the elevation of serum aspartate aminotransferase, gamma-glutamyl transferase, glucose, total cholesterol, triglycerides, and lipoprotein cholesterol concentrations induced by CORT injection (P<.05), but had no significant effect on serum CORT concentration (P>.05). PTE also significantly reduced the increased rate of abdominal fat deposition induced by CORT, decreased the average size of adipocytes, and downregulated the expression of the FAS gene (P<.05). It reversed the increase in liver total cholesterol, triglycerides, lipoprotein cholesterol, and non-esterified fatty acids content induced by CORT (P<.05). PTE had no significant effect on the expression of the glucocorticoid receptor (P>.05), but significantly upregulated the protein expression of Sirt1 and p-AMPK (P<.05), promoted the expression of lipid autophagy genes MAP1LC3B and lipolytic genes LPL, but inhibited the expression of fatty acid synthesis genes SREBP-1c, ACC, and SCD (P<.05). The addition of PTE to the diet alleviated CORT-induced oxidative stress and inflammation by enhancing T-SOD and GSH-Px activities, reducing MDA content, inhibiting p-NF-κB p65 and NLRP3 expression and the release of TNF-α and IL-1β in the serum, and increasing IL-4 content (P<.05). Overall, dietary PTE effectively regulates lipid metabolism and antioxidant status, offering a potential strategy to mitigate stress-induced metabolic disruptions in broilers. 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.

Zhigancao Decoction (ZGCD) is derived from "Treatise on Febrile Diseases" and is traditionally prescribed for treating a variety of cardiovascular conditions. As of now, there are no data to support its use as a treatment for diabetic cardiomyopathy (DCM) and the mechanism behind the effect is unclear as well. In the present study, clinical evidence for the efficacy of ZGCD in patients with DCM was examined using a meta-analysis and its underlying anti-DCM molecular mechanisms were explored via network pharmacology. The current study utilized an extensive search strategy encompassing various domestic and foreign databases databases to retrieve pertinent articles published up to June 2024. In light of this, a thorough evaluation of the benefits and safety of Zhigancao decoction (ZGCD) was conducted in this study using RevMan and Stata. Subsequently, a number of active compounds and target genes for ZGCD were gathered from the TCMSP and BATMAN-TCM databases, while the main targets for DCM were obtained from databases such as GenCards, OMIM, TTD, and DrugBank. To select core genes, protein-protein interaction networks were generated using the STRING platform, and enrichment analyses were completed using the Metascape platform. Meta-analysis results were ultimately derived from 9 studies involving 661 patients in total. In comparison with WM therapy alone, the pooled results showed that ZGCD significantly enhanced overall effectiveness. Additionally, the utilization of ZGCD was leading to a reduction in LVEDV, LVESV and LVDD, also a greater increase in LVEF. Meanwhile, the utilization of ZGCD during intervention was more effective in reducing SBP, and DBP. In addition, the ZGCD showed potential in reducing the occurrence of adverse events. In the context of network pharmacology, five constituents of ZGCD-namely lysine, quercetin, gamma-aminobutyric acid, stigmasterol, and beta-sitosterol-are posited to exert anti-diabetic cardiomyopathy (anti-DCM) effects through interactions with the molecular targets ASS1, SERPINE1, CACNA2D1, AVP, APOB, ICAM1, EGFR, TNNC1, F2, F10, IGF1, TNNI2, CAV1, INSR, and INS. The primary mechanisms by which ZGCD may achieve its anti-DCM effects are likely mediated via the AGEs/RAGE signaling pathway, as well as through pathways related to lipid metabolism and atherosclerosis. In comparison to WM therapy alone, ZGCD demonstrates greater efficacy and safety in the management of DCM. ZGCD not only significantly reduces blood pressure, but also enhances cardiac function while producing fewer adverse effects. The therapeutic effects of ZGCD on DCM can likely be ascribed to its capacity to modulate the AGEs-RAGE signaling pathway, as well as its efficacy in enhancing lipid metabolism and mitigating atherosclerosis. identifier (INPLASY202430133).

Obesity in women of childbearing age disrupts lipid metabolism in pregnancy. 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

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.

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

Impaired glucose-stimulated insulin secretion (GSIS) is a hallmark of β cell dysfunction in diabetes. Epigenetic mechanisms govern cellular glucose sensing and GSIS by β cells, but they remain incompletely defined. Here, we found that BAF60a functions as a chromatin regulator that sustains biphasic GSIS and preserves β cell function under metabolic stress conditions. BAF60a was downregulated in β cells from obese and diabetic mice, monkeys, and humans. β cell-specific inactivation of BAF60a in adult mice impaired GSIS, leading to hyperglycemia and glucose intolerance. Conversely, restoring BAF60a expression improved β cell function and systemic glucose homeostasis. Mechanistically, BAF60a physically interacted with Nkx6.1 to selectively modulate chromatin accessibility and transcriptional activity of target genes critical for GSIS coupling in islet β cells. A BAF60a V278M mutation associated with decreased β cell GSIS function was identified in human donors. Mice carrying this mutation, which disrupted the interaction between BAF60a and Nkx6.1, displayed β cell dysfunction and impaired glucose homeostasis. In addition, GLP-1R and GIPR expression was significantly reduced in BAF60a-deficient islets, attenuating the insulinotropic effect of GLP-1R agonists. Together, these findings support a role for BAF60a as a component of the epigenetic machinery that shapes the chromatin landscape in β cells critical for glucose sensing and insulin secretion.

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

DHAV-3 is one of the main causative agents of duck viral hepatitis (DVH), an acute and highly lethal infectious disease in duck industry. However, the understanding of the pathogenesis of this virus in ducklings is limited. To dissect the molecular characteristics associated with pathobiology of ducklings to DHAV-3, we applied single-cell RNA-sequencing approach to profile the transcriptome of 1.4 million cells from 14 livers of DHAV-3 susceptible (S) and resistant (R) ducklings during viral infection and 4 uninfected healthy controls. We found that infected S ducks exhibited the activation of type I and II interferon pathways with elevated expression of interferon-stimulated genes (ISGs) compared to infected R ducks and healthy controls. DHAV-3 promoted proinflammatory phenotype and inhibited the cell apoptosis pathway of Kupffer cells of S ducks. Furthermore, we observed the elevated expression of host factor PLAC8 in S ducks and validated its ability to facilitate the infection of DHAV-3. We identified significant dysregulation of various genes in complement and coagulation cascades in hepatocytes2 exclusive to S ducks, together with over-secretion of ANGPTL4 from endothelial cells in S ducks which is confirmed to promote cellular migration, suggesting etiology of coagulopathic complications in ducks with severe DVH. Collectively, this study provides a rich resource for understanding the inflammatory immune signatures and cell communications underlying the pathogenesis of DHAV-3 infection, which may accelerate the development of better diagnostic methods and strategies for controlling this disease.

Ischemic injury induces a partial mesenchymal shift in endothelial cells (ECs), contributing to impaired vascular regeneration. However, the molecular regulators of this transitional state remain poorly defined. To address this, we performed circular RNA profiling of endothelial cells under ischemic-like conditions and identified a marked upregulation of a circular RNA, named circATXN1. Functional studies revealed that circATXN1 knockdown modulates endothelial phenotype and vascular response after ischemia. Functional studies have shown that knockdown of circATXN1 can regulate the endothelial cell phenotype and vascular response after ischemia. Mechanistically, circATXN1 knockdown enhances the demethylase protein ALKBH5 to reduce the RNA methylation level of the key transcription factor SLUG, thereby stabilizing SLUG. In animal models, suppression of circATXN1 enhances angiogenesis and improves recovery following ischemic injury. Here, we show that circATXN1 regulates partial endothelial-to-mesenchymal transition (EndMT) and angiogenesis by controlling SLUG mRNA methylation dynamics, highlighting its potential as a therapeutic target in ischemic disease.
