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

The Lipoprotein(a) (LPA) rs3798220 and rs10455872 polymorphisms have been indicated to be involved with the coronary heart disease (CHD) susceptibility. However, there are still differences between the individual studies. To explore the correlation of LPA gene rs3798220 and rs10455872 polymorphisms and CHD, the current meta-analysis was performed. The random or fixed effect genetic models were used to calculate the pooled odds ratios (ORs) and their corresponding 95 % confidence intervals (CI). A significant association was found between LPA rs3798220 polymorphism and CHD under allelic (OR: 1.488), recessive (OR: 1.543), dominant (OR: 1.534), homozygous (OR: 1.544), heterozygous (OR: 1.498) and additive genetic models (OR: 1.531). There was also a significant association between LPA rs10455872 polymorphism and CHD under allelic (OR: 1.607), dominant (OR: 1.751), heterozygous (OR: 1.723) and additive genetic models (OR: 1.686). LPA rs3798220 and rs10455872 polymorphisms were significantly associated with increased CAD risk. The persons carrying C allele of LPA rs3798220 and G allele of LPA rs10455872 polymorphisms might have higher CHD risk than the T allele of rs3798220 or A allele of rs10455872 carriers. Show less

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

Tripartite motif-containing protein 21 (TRIM21), an E3 ubiquitin ligase of the TRIM superfamily, modulates critical cellular processes including ubiquitination, autophagy, and oxidative stress response. Accumulating evidence highlights its context-dependent regulatory roles in hepatocellular carcinoma (HCC)-the most prevalent primary liver malignancy with high mortality and limited therapeutic efficacy. This review systematically summarizes the core mechanisms by which TRIM21 orchestrates HCC progression: ① Autophagy regulation: TRIM21 modulates HCC autophagy via multiple axes, including CCR4-NOT complex (TNKS1BP1/CNOT4)-mediated substrate ubiquitination, ATG14-dependent autophagosome initiation, and RETREG1-driven reticulophagy, with context-dependent effects on tumor proliferation. ② Drug resistance: TRIM21 enhances oxaliplatin sensitivity by ubiquitinating and degrading G6PD (the rate-limiting enzyme of the pentose phosphate pathway), while its role in sorafenib resistance involves dual pathways-the MST1/YAP axis and the ApoE/cholesterol/PI3K-AKT cascade. ③ Metastasis suppression: TRIM21 restricts HCC invasion and metastasis by ubiquitinating key oncoproteins, preserving epithelial integrity and inhibiting mesenchymal transition. ④ Reactive oxygen species (ROS) balance: TRIM21 regulates oxidative stress in HCC via the SQSTM1/p62-Keap1-NRF2 axis, coordinating with HIF1α to modulate antioxidant responses and tumor cell survival. Additionally, we discuss the regulatory significance of TRIM21 in HCC associated with hepatitis B virus (HBV) infection (via HBx/DNA polymerase ubiquitination) and nonalcoholic steatohepatitis (NASH) (via suppressing lipogenic enzymes to reduce steatosis-driven carcinogenesis). This review provides a theoretical basis for TRIM21 as a potential diagnostic marker and therapeutic target for HCC. Show less

We aim to examine prospective associations of longitudinal adherence to antihypertensive medication, A longitudinal cohort using 12-year survey data from wave 8 (2006) to wave 14 (2018) in the Health and Retirement Study, an ongoing national survey recruiting community-dwelling adults aged ≥50 years in the United States. Longitudinal adherence to antihypertensive medication was evaluated during wave 8 (2006) to wave 10 (2010), based on self-reported antihypertensive medication use at each wave. Incident dementia cases were ascertained during wave 10 (2010) to wave 14 (2018) by combining self-reported diagnosis and standardized cognitive batteries, excluding prevalent cases during the medication adherence evaluation period. Cox proportional hazard regression was utilized to assess dementia risk, with adjusted hazard ratios (HR) and 95% CIs calculated, controlling for sociodemographic characteristics, socioeconomic status indicators, lifestyle factors, and clinical conditions, as well as blood pressure measurements. A total of 18 469 participants were screened, after which 11 835 participants (mean [SD] age: 66.2 [10.1] years; men: 40.6%) were included, with 1136 incident dementia cases. After controlling blood pressure and other known risk factors, hypertension participants who persistently adhered to antihypertensive medication during follow-up had a 27% lower dementia risk (HR, 0.73 [95% CI, 0.61-0.87]) than the low adherence group, which was more evident than the associations between baseline antihypertensive medication use and dementia. The difference in dementia risk was insignificant when comparing the high adherence group with the normotension group (HR, 1.03 [95% CI, 0.88-1.21]). The results were consistent in non- Persistently adhering to antihypertensive medication was consistently associated with a lower subsequent dementia risk in community-dwelling middle-aged and older adults.

Brain-derived neurotrophic factor (BDNF) plays an important role in the survival of dopaminergic neurons. Clinical studies have suggested that serum BDNF levels are reduced in patients with Parkinson's disease (PD). However, no study has investigated peripheral BDNF levels and BDNF Val66Met polymorphism in the prodromal stage of PD and their relationship with disease conversion. In total, 120 patients with video-polysomnography confirmed isolated REM sleep behavior disorder (iRBD) and 120 healthy controls (HCs) were enrolled. Genetic analyses were performed, and plasma levels of BDNF were measured. All patients with iRBD underwent comprehensive clinical testing, and 107 iRBD patients were prospectively followed up. Plasma BDNF levels were significantly lower in the iRBD group than in HCs (18,878.85 pg/mL vs. 24,649.85 pg/mL, p = 0.002), but no differences were observed in BDNF Val66Met carrier rates between the two groups. Plasma BDNF levels did not differ significantly between BDNF Val66Met carriers and noncarriers. Notably, higher plasma BDNF levels were associated with an increased risk of short-term disease conversion (hazard ratio = 3.418, 95% CI: 1.520-7.684, p = 0.003), whereas BDNF Val66Met carrier rates showed no such association. Our findings suggest that plasma BDNF is significantly associated with iRBD and may likely serve as a prognostic biomarker for the development of neurodegenerative disease. However, the BDNF Val66Met polymorphism may not be involved in the pathogenesis of iRBD as well as phenoconversion in the studied population. Show less

Backfat thickness, a key selection trait in pig-breeding programmes, has traditionally been measured as a homogeneous layer. However, backfat is anatomically structured into three distinct layers, and each layer likely contributes differently to carcass quality. In addition, previous studies have shown that the deposition of the third layer of backfat is phenotypically correlated with intramuscular fat (IMF). Therefore, targeted selection for specific backfat layers, particularly the third layer, represents a potential strategy to increase IMF content while maintaining a high lean meat percentage. However, the genetic architecture of these distinct porcine backfat layers remains poorly understood. The aim of this study was to estimate the genetic parameters and identify key candidate genes underlying the three backfat layers. We collected B-mode ultrasound images from 561 Landrace pigs to measure individual layer thickness, followed by DNA extraction, genotyping, genetic parameter estimation, and a genome-wide association study (GWAS). Our measurements showed that the first layer of backfat (FBF) is the thickest, followed by the second (SBF) and the third (TBF) layers. Genetic parameter estimation yielded heritability estimates of 0.37, 0.42, 0.38, 0.34, 0.32, 0.24, and 0.21 for total backfat (BF), FBF, FBF/BF, SBF, SBF/BF, TBF, and TBF/BF, respectively. Through integrated analysis of GWAS, Bayesian fine-mapping, and gene annotation, we identified 15 non-redundant candidate genes associated with different backfat layers. These included two genes (SOAT1 and ACBD6) shared by BF and SBF, LPL for BF and FBF, and CAND1 for TBF and TBF/BF. Additionally, SERPINA12 and SERPINA6 were associated with BF; PRKAG1 and PRDM16 with FBF; EPRS1 and SLC39A10 with FBF/BF; PTGES and CRAT with SBF; and ACLY, CAVIN1, and PDZRN3 with SBF/BF. Our results indicate that each layer is governed by a distinct set of genes, which advances our understanding of the genetic basis of backfat layers in pigs. Show less

Probiotics such as The intestinal colonization ability of CIQ249 was assessed using cFDA-SE labeling and flow cytometry. Growth performance and intestinal morphology were evaluated in mice. Antimicrobial activity of CIQ249 cell-free supernatant was tested against various pathogens, and pathogen damage was visualized by scanning electron microscopy. Protective effects against CIQ249 demonstrated strong intestinal colonization and increased villus height and the villus-to-crypt ratio, contributing to improved growth performance. Its cell-free supernatant selectively inhibited enteropathogens and induced structural damage in CIQ249 enhances mucosal defense against enteropathogenic bacteria through a dual mechanism-strengthening the epithelial barrier and activating a coordinated DC-Tfh-IgA immune axis. These findings provide a multi-level mechanistic basis for its application as a microecological agent against intestinal infections. Show less

Disruption of circadian rhythms is increasingly recognized as a contributor to cognitive dysfunction, but its role in gestation-associated cognitive changes remains unexplored. Here we combine human cognitive screening with a comprehensive longitudinal mouse model to investigate whether gestational cognitive impairment and postpartum recovery are coupled with disruption and restoration of hippocampal circadian rhythms. Cognitive function was assessed in pregnant and postpartum women using the Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE). In mice, four reproductive stages were compared: control, gestation, 1 month postpartum, and 3 months postpartum. Serum gonadotropins and sex hormones levels were quantified using ELISA. Home-cage locomotor activity was recorded over 48 h under a 12 h:12 h light-dark cycle. Hippocampal-dependent memory was evaluated using the novel object recognition test and Barnes maze at Zeitgeber times ZT6 (day) and ZT18 (night). Hippocampal amyloid β (Aβ) deposition was visualized via immunofluorescence; protein expression of amyloid precursor protein (APP), β-site amyloid precursor protein cleaving enzyme-1 (BACE1), and phosphorylated tau was measured by Western blots. Hippocampal clock gene expression was quantified by RT-qPCR at six time points; circadian parameters (mesor, amplitude, acrophase) were derived by cosinor analysis and compared between groups. Human cognitive screening confirmed modest gestational decline with postpartum recovery. In mice, gestation disrupted daily locomotor activity rhythms and reduced nocturnal preference; both partially recovered by 1 month and fully by 3 months postpartum. Behaviourally, pregnancy impaired the normal day-night difference and performance in novel object exploration and Barnes maze, which recovered progressively. At the molecular level, gestation increased hippocampal APP and BACE1 expression, elevated Aβ42 deposition, and induced tau hyperphosphorylation at multiple sites-hallmarks of Alzheimer's disease-related pathology. These alterations partially reversed by 1 month postpartum and normalized by 3 months. Hippocampal clock genes maintained 24 h rhythmicity, but gestation induced gene-specific phase shifts, amplitude reductions, and mesor alterations. These parameters showed gradual, gene-dependent normalization postpartum. Gestational cognitive impairment and postpartum recovery are associated with reversible disruption and restoration of both hippocampal circadian rhythms and Alzheimer's disease-related molecular pathology. These findings are correlational in nature and provide a foundation for future causal investigations. Show less

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

Hypertensive heart disease (HHD) and hypertrophic cardiomyopathy (HCM) are characterized by left ventricular hypertrophy and diastolic dysfunction. Despite overlapping remodeling features, their distinct mechanisms and therapeutic responses remain unclear. This study integrated genetic, imaging, and proteomic data to identify key mediators underlying β1-adrenergic receptor blockers (β1-blockers)-related therapeutic heterogeneity between HHD and HCM. Genetic instruments for β1-blockers were derived from two genome-wide association studies and integrated with cardiac magnetic resonance radiomic traits and plasma proteomic data from the UK Biobank, along with disease outcomes from FinnGen. A refined two-stage network Mendelian randomization framework with pleiotropy-robust estimators identified mediators of treatment response. To further elucidate their biological and clinical significance, additional analyses were performed, including drug-target profiling, molecular docking, adverse events (AEs) assessment, and drug prediction. We identified three types of imaging features and ten mediator proteins that contributed to therapeutic responses in HHD and HCM. These mediators were categorized as either mediating (aligned with therapeutic outcomes) or suppressing (opposing therapeutic outcomes). Left ventricular regional radial strain acted as a suppressing factor in HHD but a mediating factor in HCM, whereas end-diastolic and end-systolic volumes consistently showed suppressing effects in both. Regional myocardial wall thickness also exerted a suppressing role in HCM. Among protein mediators, APOE, CGREF1, ITGA5, LSP1, NOS3, and NPPB were linked to HHD, whereas DUSP13, ITGA11, NID1, and SERPINA4 were related to HCM. Specifically, APOE, ITGA5, NOS3, NPPB, DUSP13, and ITGA11 acted as mediating factors, while CGREF1, LSP1, NID1, and SERPINA4 served as suppressing ones. These findings remained robust after pleiotropy adjustment and other genetic analyses. Molecular docking revealed interactions between ADRB1, the β1-blockers target, and downstream proteins, while drug prediction identified eight potential compounds linked to these mediators. Additionally, AE analyses indicated that some targets, such as DUSP13, could both mitigate and aggravate common AEs while contributing to cardiac therapy. This integrative multi-omics analysis revealed distinct imaging and proteomic mechanisms of genetically proxied β1-blockers in HHD and HCM, providing genetic evidence for differential therapeutic responses and highlighting molecular targets for precision cardiovascular therapy.

Tyrosine kinase inhibitors (TKIs) have transformed the treatment of EGFR-mutant non-small cell lung cancer (NSCLC); however, acquired resistance remains a major clinical challenge. While lysosomes have been implicated in drug resistance, their precise role in EGFR-TKI resistance remains unclear. In this study, we found that EGFR-TKI, including gefitinib and osimertinib, impaired WWP2-mediated proteasomal degradation of LAPTM4B. Through analysis of clinical tumor samples, genetic manipulation, and functional assays, we identify the lysosomal protein LAPTM4B as a key driver of EGFR-TKI resistance by enhancing EGFR phosphorylation and downstream signaling. Mechanistically, LAPTM4B interacts with ATP1A1 and facilitates its endocytosis, while simultaneously preventing its degradation by suppressing TRIM8-mediated K63-linked ubiquitination and proteasomal turnover. This stabilization of ATP1A1 enhances lysosomal acidification, ultimately promoting EGFR-TKI resistance. To identify potential therapeutic strategies, we conducted an unbiased high-content drug screen and identified compounds that suppress LAPTM4B expression. These compounds synergistically enhance the efficacy of EGFR-TKIs in NSCLC models Show less

Diabetes mellitus (DM) is hypothesized to increase the risk of Alzheimer's disease (AD). However, existing studies have yielded conflicting results, with some demonstrating a significant association between DM and AD risk while others have not. Therefore, this meta-analysis aimed to systematically evaluate the association between DM and AD risk. Comprehensive searches were conducted in PubMed, Web of Science, and Embase databases to identify cohort or case-control studies investigating the association between DM and AD risk. All eligible studies published before October 2025 were included. The Newcastle-Ottawa Scale (NOS) was used to assess the risk of bias. Hazard ratio (HR) and 95% confidence interval (CI) were pooled as the effect size for meta-analysis. Heterogeneity among studies was evaluated using Cochran's A total of 11 studies involving 3,393,545 participants were included. A meta-analysis revealed that DM was significantly associated with an increased risk of AD (HR = 1.36, 95% CI (1.19, 1.55), This meta-analysis provides compelling evidence that DM is an independent risk factor for AD, offering important implications for clinical practice and future research. However, due to the methodological limitations of this study, the results should be interpreted with caution. Large-scale, high-quality prospective cohort studies are needed to fully investigate the relationship between DM and AD risk. https://www.crd.york.ac.uk/prospero/, identifier CRD420251159844.

Major depressive disorder (MDD) in adolescents is a critical public health concern, yet objective diagnostic biomarkers remain lacking. We conducted an integrative lipidomics study across human cohorts and a chronic unpredictable mild stress (CUMS) rat model. Targeted UPLC-MS/MS profiling was applied to a training cohort (95 MDD, 40 controls), and untargeted UPLC-HRMS profiling to an independent cohort (56 MDD, 37 controls). Candidate biomarkers were identified using univariate tests, partial least squares discriminant analysis, and three feature-selection methods (Boruta, LASSO, RFE), with predictive performance evaluated by cross-validation and external replication. Translational relevance was examined in CUMS rats through behavioral assays and lipidomic profiling of serum and brain tissues. Pathway enrichment and regression models explored metabolic context and clinical associations. In the training cohort, we found that 244 lipids were significantly altered, highlighting altered glycerophospholipid, glycerolipid, and sphingolipid metabolism. A 29-lipid panel achieved 90.4% cross-validation accuracy, while a reduced 7-lipid subset reached 94.8%. In the validation cohort, an 8-lipid panel achieved 71.2% accuracy, and a minimal 2-lipid set-LPA(18:2) and SPH(d16:1)-reached 72.1%. Cross-species analysis confirmed consistent downregulation of SPH(d16:1) in serum of both humans and rats, and of LPC(0:0/16:0) specifically in the rat prefrontal cortex. Regression analyses linked sex, age, and anxiety severity to lipid alterations. This cross-platform, cross-species study identifies reproducible lipid signatures of adolescent MDD, highlights SPH(d16:1) and LPC(0:0/16:0) as translational biomarkers, and implicates glycerophospholipid metabolism in MDD pathophysiology, providing a foundation for biomarker-guided diagnostics and therapeutics.

Gliomas comprise a heterogeneous group of central nervous system tumors in which gene fusions (GFs) are significant oncogenic drivers and emerging diagnostic and therapeutic biomarkers. In cancer diagnosis, GF detection largely relies on targeted short-read sequencing fusion panels, such as the Children's Hospital of Philadelphia (CHOP) Fusion Panel (FUSIP). While these panels are effective for detecting recurrent, well-characterized GFs, they are limited to predefined gene sets and cannot identify full-length transcripts. Here, we analyzed 49 high- and low-grade gliomas previously classified as fusion-negative by FUSIP using an untargeted whole-transcriptome RNA sequencing approach with Oxford Nanopore Technologies (ONT) long-read sequencing. This enabled transcriptome-wide fusion discovery of additional known and potentially novel oncogenic GFs beyond panel constraints. Long-read sequencing further allowed direct resolution of full-length fusion transcripts and their associated isoform structures. By integrating GF detection with isoform-level transcript analysis, we identified fusion-associated transcript isoforms with alternative splicing patterns that aligned near reported GF breakpoints, including Show less

To ascertain the level of psychological resilience, examine the latent profiles of individuals within infertile couples who experience recurrent implantation failure (RIF), identify the relevant influencing factors, and lay a foundation for developing customized intervention strategies. Convenience sampling was adopted in this study. Participants were selected from individuals in infertile couples with RIF who attended the Second West China Hospital of Sichuan University between November 2024 and July 2025. Data were collected via a general information questionnaire and validated scales assessing psychological resilience, social support, sleep quality, family adaptability and cohesion, anxiety, and depression. Latent profile analysis (LPA) was performed to explore the psychological resilience profiles of individuals with RIF, while univariate analysis and multivariate Logistic regression analyses were employed to identify the influencing factors associated with different profile categories. A total of 303 valid questionnaires were collected, including 194 from females and 109 from males. The overall psychological resilience score was (26.66 ± 6.319). Latent profile analysis categorized psychological resilience into three subgroups: the low tenacity-low strength subgroup (31.4%), the moderate tenacity-moderate strength subgroup (53.1%), and the high tenacity-high strength subgroup (15.5%); Multivariate Logistic regression analysis indicated that gender, family adaptability and depression severity (all Marked interindividual heterogeneity exists in the psychological resilience of individuals with RIF.

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

Diabetic kidney disease (DKD) is a major diabetic complication that often progresses to end-stage renal disease and causes high mortality. Early diagnosis is essential for effective prevention and treatment. To explore the underlying mechanisms of DKD and identify plasma biomarkers for early diagnosis. In this study, healthy adults and individuals with diabetes mellitus (classified into normal albuminuria (NA), microalbuminuria (MI), and macroalbuminuria (MA) groups) were recruited. Plasma samples were collected from all participants, and 12 subjects per group were then randomly selected as a discovery cohort for proteomic analysis. Proteomics identified 95 differentially expressed proteins (DEPs) among the groups. These DEPs associated pathways evolved in a stage-specific manner in which inflammation dominated the early NA/Ctrl stage, complement and coagulation cascades became the main drivers during MI/NA, and MA/MI exhibited newly emerged disturbances in oxidative detoxification, lysosomal function, and nitrogen metabolism alongside sustained complement and coagulation changes. Among them, the complement and coagulation cascades were closely related to DKD progression. Through hub protein analysis, five proteins (FGG, ITIH4, A2M, C3, and APOE) that showed consistent trends across disease stages were identified as potential diagnostic biomarkers for DKD. Our research provides new insights into the mechanisms and early diagnosis of DKD. Show less

Decline in pulmonary function (PF) and respiratory muscle strength (RMS) is influenced by environmental and genetic factors and is inconsistently linked to cognitive outcomes. This study explores the associations between PF, RMS, and cognitive function among community-dwelling older adults in China, analyzing interactions with APOE Ɛ4 and the mediating effect of serum total bilirubin. About 1,081 Hubei Memory and Aging Cohort (HMACS) participants underwent PF (PEF, FEV1 and FVC), RMS (MIP and MEP) assessment, cognitive tests, APOE genotyping, and bilirubin measurement. Multivariate logistic regression and general linear regression were used to analyze associations. Among 1,081 participants (mean age 70.52 ± 5.55 years), 26.1% had cognitive impairment. Lower PF and RMS scores were associated with cognitive impairment. Higher comprehensive PF (c-PF) and RMS indices protected against cognitive impairment (eg, c-PF: OR = 0.482-0.609, PF (especially PEF) and RMS (especially MEP) indices are significantly associated with cognitive function and impairment in older adults, independent of APOE Ɛ4 status.

Ox-LDL-induced macrophages and high-fat diet (HFD)-fed ApoE A substantial content of inflammatory factors, the activation of NLRP3/GSDMD/CASP3/CASP8/RIPK3/pMLKL, and the upregulation of galectin-3 were detected in advanced human and mouse atherosclerotic lesions. Galectin-3 was predominantly expressed in atherosclerotic macrophages, and Galectin-3-positive macrophages were mainly distributed in the atherosclerotic core in comparison with the proximal adjacent artery. Ox-LDL induced apoptosis, pyroptosis and necroptosis in macrophages, as evidenced by the activation of NLRP3/GSDMD/CASP3/CASP8/RIPK3/pMLKL and the secretion of proinflammatory cytokines. Galectin-3 interacted with NLRP3. Genetic knockdown of galectin-3 alleviated ox-LDL-induced activation of inflammatory cell death, which was pronouncedly abrogated by NLRP3 agonist nigericin. Genetic galectin-3 deficiency attenuated, and conversely nigericin exacerbated macrophage death, vascular inflammation and atherosclerosis in HFD-fed ApoE Macrophage-derived galectin-3 contributed to pyroptosis, apoptosis and necroptosis in concert, promoted vascular inflammation and atherosclerosis through the upregulation of TLR4/MyD88/NF-κB/NLRP3 pathway. Pyroptosis, apoptosis, and necroptosis of macrophages occur concurrently in atherosclerosis. Galectin-3 and NLRP3 expression levels are elevated in both human and murine atherosclerotic lesions. Galectin-3 is predominantly expressed in macrophages within atherosclerotic plaques.Galectin-3 interacts with NLRP3, activates TLR4/MyD88/NF- Show less

Lecanemab, an anti-amyloid beta (Aβ) protofibril antibody, was introduced in China in 2024, but its real-world performance remains unknown. In this prospective, multicenter study across 21 sites, 261 Alzheimer's disease patients (mild cognitive impairment to moderate dementia) received biweekly lecanemab (10 mg/kg). A matched Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort served as comparator. Cognitive tests, plasma biomarkers, and optional amyloid/tau positron emission tomography (PET) were assessed over 6 months. Lecanemab significantly attenuated cognitive decline versus ADNI. Plasma Aβ42, Aβ40, phosphorylated tau 217 (p‑tau217), glial fibrillary acidic protein (GFAP), and ratios showed robust changes; a p‑tau217 reduction correlated with amyloid PET clearance (mean -22.1 Centiloid; 29.2% turned amyloid-negative). Apolipoprotein E (APOE) ε4 non-carriers showed greater improvements. Infusion reactions occurred in 11.1% and amyloid-related imaging abnormalities in 9.2% (1.6% symptomatic), with no stage-related safety differences. Lecanemab was effective and well tolerated in real-world Chinese patients. Plasma p‑tau217 may serve as a sensitive, minimally invasive treatment-response biomarker. Show less

To characterize ultra-processed food (UPF) circulating metabolic signatures associated with Crohn's disease (CD) and to localize key metabolic mediators linking UPF intake to CD risk. Prospective cohort study. Two large multi-center cohorts (UK Biobank [UKB] and Whitehall II [WHII] study) across the UK and an Eastern multi-center cohort ONE-IBD Study from China. 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

Neonatal regulatory T (Treg) cells in secondary lymphoid organs have greater proliferative capacity and more potent suppressive functions than adult Treg cells. However, the phenotypic and functional features of Tregs in neonatal nonlymphoid organs are not well understood. Our prior work demonstrated that thymus-derived Treg cells entering the neonatal mouse liver enhance immune tolerance and periportal liver maturation. Compared to splenic Treg cells, these hepatic Tregs have faster turnover and superior suppression of naïve T-cell proliferation. To further define this population, we conducted single-cell transcriptomic and immunophenotypic analyses of liver- and spleen-derived Tregs from neonatal and adult mice. Our analysis revealed a distinct T-box transcription factor Tbx21 (T-bet) Show less

Cutaneous squamous cell carcinoma (cSCC) involves complex immune interactions. This study aimed to identify a T cell-related gene signature to characterize the immune landscape and aid in molecular diagnosis. We integrated single-cell RNA sequencing (scRNA-seq) and five bulk microarray datasets, utilizing an independent RNA-seq cohort for external validation. Feature genes were identified from the intersection of scRNA-seq-defined T cell-related genes (TRGs) and bulk differentially expressed genes using machine learning. A diagnostic nomogram was constructed, and its performance was assessed via ROC curves. In addition, immune infiltration, immunofluorescence staining, drug interactions, and clinical expression (qRT-PCR) were evaluated. Screening yielded 28 T cell-related DEGs enriched in extracellular matrix functions. machine learning selected a core signature: APOE, CYBA, and S100A2. The diagnostic model demonstrated high diagnostic performance in the studied cohorts (AUC > 0.9) across training and external validation cohorts. Clinically, qRT-PCR supported significant upregulation of CYBA and S100A2. APOE exhibited distinct immunomodulatory connectivity, correlating positively with Th17 cells and negatively with Tregs, whereas CYBA and S100A2 were associated with Treg infiltration. Immunofluorescence results revealed significantly elevated levels of S100A2 and Foxp3 in cSCC tissues compared to the control group. Pharmacogenetic analysis highlights the association of these genes, particularly the APOE gene, with drug response. This T cell-associated signature highlights the potential link between molecular diagnosis and immune characterization. Specifically, CYBA and S100A2 are identified as promising diagnostic candidate signatures, while APOE may reflect immunomodulatory heterogeneity. These findings offer insights for developing diagnostic strategies and targeted immunotherapies in cSCC. Show less

The brain is vulnerable to DNA damage and cardiometabolic risk. Yet, whether genetic variation in DNA repair interacts with cardiometabolic factors to explain cognitive variability remains unclear. Participants (n = 376,533) of white-British ancestry from the UK biobank with cognitive, neuroimaging, and whole-exome sequencing data were included. Six cognitive outcomes were assessed: fluid intelligence (FIQ), symbol-digit matching task (SDMT), visual matching (MATCH), trail making (TRAIL1 and TRAIL2), and prospective memory (PMEM). Seven brain regions of interest were assessed: total brain (TBV), grey matter (GMV), left and right white matter (LWM/RWM), left and right hippocampi (LHC/RHC), and white matter hyperintensities (WMH) volumes. A total of 3487 genetic variants across 39 DNA repair genes were tested. SNP and gene/gene-set level associations were tested using regression models adjusted for age, sex, APOE ε4, ancestry, and outcome-specific covariates. Genetic interactions with a multidimensional cardiometabolic risk index (CMRI), encompassing established risk factors, were assessed. We detected 107 genetic variants (mostly extremely rare) across 36 DNA repair genes associated at Bonferroni-significance (p ≤ 1.4 × 10 Show less

Vascular senescence is a fundamental driver of age-related cardiovascular diseases, yet the epigenetic mechanisms controlling this process remain poorly understood. This study investigated the role and underlying mechanisms of lysine acetyltransferase 8 (KAT8), a key histone acetyltransferase, in maintaining endothelial cell homeostasis and preventing vascular senescence. We found that KAT8 expression is consistently downregulated in human aged vessels, senescent rats and mice, and cellular models of aging. Using CRISPR-Cas9-based loss-of-function and gain-of-function approaches in endothelial cells, C57BL/6J mice, and ApoE Show less
