Women with autoimmune diseases (AIDs) experience chronic immune dysregulation and hormonal fluctuations, both of which may influence breast cancer risk. However, it remains unclear whether this risk is driven mainly by its treatment or the underlying disease, highlighting the need for integrating real-world data and genetic evidence. The FDA Adverse Event Reporting System (FAERS) were utilized to identify breast cancer safety signals among women with AIDs, analyzing 11,479 reports from 2004 to 2024. Disproportionality analyses using Reporting Odds Ratio (ROR) and Information Component (IC) were conducted. Then, we mapped these drugs to their target genes and performed mendelian randomization (MR) to assess their causal relationships with breast cancer. Finally, we investigated shared genetic architecture between breast cancer and AIDs using global and local genetic correlation, cross-trait meta-analysis, and transcriptome-wide association studies. We identified 13 immunosuppressive drugs (TNF inhibitors, interleukin inhibitors, and monoclonal antibodies), 3 immunostimulants and 16 adjunctive drugs associated with increased breast cancer reporting in patients with AIDs. The drugs with the highest case reports for positive disproportionality analysis were interferon beta-1a (N: 1731, IC [IC025] 1.56 [1.49]), natalizumab (798, 0.65 [0.54]), and infliximab (741, 0.64 [0.53]). MR results revealed causal links between 9 drug targets and breast cancer risk, such as FDPS (OR: 0.66, p: 1.33E-08), CALCRL (OR: 0.887, p: 4.77E-06) and PARP1 (OR: 1.051, p: 3.50E-06). Global genetic correlation identified significant shared heritability between breast cancer and 3 specific AIDs, including type 1 diabetes mellitus (rg: -0.242, p: 0.95E-4), ulcerative colitis (rg: 0.125, p: 0.29E-2), and migraine (rg: 0.078, p: 0.79E-2). Specifically, the most notable genetic overlap was observed between breast cancer and type 1 diabetes mellitus, with significant shared risk SNPs (rs12046289 and rs6679677) and susceptibility genes (ADCY3 and CENPO). Our study uncovered several immune-related drugs associated with increased breast cancer reporting in women with AIDs. This risk may be explained by several potential drug targets with causal roles, or by the shared genetic comorbidity between specific AIDs and breast cancer. These insights emphasize the need for tailored breast cancer surveillance and highlight potential molecular targets for intervention in vulnerable populations. Show less

Cardiovascular disease (CVD) is the leading cause of mortality in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), yet traditional risk predictors remain limited in clinical practice. To develop machine learning (ML) models for classifying prevalent atherosclerotic cardiovascular disease (ASCVD) risk in MASLD patients, and to enhance model interpretability using SHapley Additive exPlanations (SHAP). Methods: This retrospective study included 590 MASLD patients diagnosed at the Affiliated Hospital of Qingdao University between December 2019 and December 2024. Patients were randomly divided into a training set (n=413) and a validation set (n=177), and further stratified based on ASCVD status. Least absolute shrinkage and selection operator (LASSO) regression was used for feature selection. Six ML models were developed and evaluated using sensitivity, specificity, accuracy, area under the receiver operating characteristic curve (AUC), and F1 score. SHAP analysis was performed to interpret feature contributions. ASCVD was present in 434 of 590 patients (73.6%). The Gradient Boosting (GB) model achieved the best performance, with AUCs of 0.918 (95% CI: 0.890-0.944) in the training set and 0.817 (95% CI: 0.739-0.883) in the validation set. SHAP analysis identified the top predictors as the Cholesterol-HDL-Glucose (CHG) index, Castelli Risk Index II (CRI-II), lipoprotein(a) [Lp(a)], serum creatinine (Scr), and uric acid (UA). The GB model demonstrated strong high accuracy in identifying existing ASCVD in MASLD patients and may serve as a useful tool for early risk stratification in clinical settings. Show less

Injectable hydrogel implants represent a promising therapeutic approach for ischemic heart failure; but their efficacy is often limited by low bioactivity, poor durability, and inadequate injection techniques. Herein, a unique hydrogel incorporating extracellular matrix from fish swim bladder (FSB-ECM), which has distinct advantages over mammalian derived ECM, such as low antigenicity, bioactivity, and source safety, is developed. It consists of collagen, glycoproteins, and proteoglycans, including 13 proteins common in the myocardial matrix and three specific proteins: HSPG, Col12a1, and vWF. This hydrogel enhances cardiac cell adhesion and stretching while promoting angiogenesis and M2 macrophage polarization. In addition, its storage modulus (G') increases over time, reaching about 1000 Pa after 5 min, which facilitates transcatheter delivery and in situ gelling. Furthermore, this hydrogel provides sustained support for cardiac contractions, exhibiting superior longevity. In a rat model of ischemic heart failure, the ejection fraction significantly improves with FSB-ECM treatment, accompanied by increased angiogenesis, reduced inflammation, and decreased infarct size. Finally, RNA sequencing combined with in vitro assays identifies ANGPTL4 as a key protein involved in mediating the effects of FSB-ECM treatment. Overall, this new injectable hydrogel based on FSB-ECM is suitable for transcatheter delivery and possesses remarkable reparative capabilities for treating heart failure. Show less

Pesticides increase agricultural productivity, but with the widespread use of pesticides, concerns have arisen about their potential negative impacts on human health and aquatic organisms. Pydiflumetofen (PYD) is a novel chiral fungicide, and the potential environmental and health hazards of PYD and its chiral isomers are not sufficiently understood. In this work, zebrafish were employed as a model organism to study the toxicity of PYD, specifically investigating the developmental and cardiovascular toxicities in zebrafish exposed to 0.2 μg/mL of PYD for 72 h. The results showed that PYD severely impeded the development of zebrafish embryos, resulting in abnormal hatching rates, enlarged yolk sacs and shortened body length. In addition, PYD resulted in morphological and functional abnormalities of the embryonic heart and blood vessels, such as pericardial edema, linearization of the heart, impeded vascular production, slowed heart rate, and reduced erythrocyte flow rate. Mechanistically, we found that PYD caused oxidative stress, lipid accumulation and apoptosis in zebrafish. Simultaneously, the expression of genes associated with cardiac (nkx2.5, gata4, tbx5, hand2, has2) and vascular (vegfc, dll4, cdh5, hey2, and notch3) development was altered. Notably, our results indicate that (+)-R-PYD exhibits higher developmental and cardiovascular toxicity than (-)-S-PYD. This paper first reveals the cardiovascular toxicity of PYD and opens new avenues for assessing the environmental and health hazards caused by chiral fungicides. Show less

Pancreatic cancer is characterized by a poor prognosis and limited responsiveness to conventional therapies, presenting a substantial therapeutic challenge. Although chemotherapy remains the cornerstone of systemic treatment, options become scarce once frontline therapies fail. While targeted therapies and immunotherapies have emerged as potential alternatives, their efficacy in pancreatic cancer is not well established. As research advances, exploring the tumor immune microenvironment (TiME) of pancreatic cancer is crucial and holds significant potential for developing novel treatment strategies.We report a case of a pancreatic cancer patient who, after the failure of frontline and second-line treatments, was treated with a pioneering combination of targeted therapy and immunotherapy to modulate the unique TiME. The targeted agent, surufatinib, is a tyrosine kinase inhibitor (TKI) that targets vascular endothelial growth factor receptor (VEGFR) 1-3, fibroblast growth factor receptor 1 (FGFR1), and colony-stimulating factor 1 receptor (CSF-1R). The immunotherapy agent, toripalimab, is an immune checkpoint inhibitor targeting programmed cell death protein 1 (PD-1). Remarkably, the patient benefitted from this regimen, exhibiting stable disease, improved clinical symptoms, and prolonged progression-free survival. This case highlights the potential of personalized therapy in treating pancreatic cancer, particularly in patients with distinctive features of the TiME that may predict favorable responses to immunotherapy. Personalized strategies that consider the spatial structure and composition of the TiME may offer a promising avenue for achieving long-term progression-free survival in patients with pancreatic cancer.

Tumor fibrosis is recognized as a malignant hallmark in various solid tumors; however, the clinical importance and associated molecular characteristics of tumor fibrosis in liver metastases (LM) from colorectal cancer (CRLM) remain poorly understood. Here we show that patients with CRLM whose liver metastases (LM) exhibited tumor fibrosis (Fibrosis+ LM) had significantly worse progression-free survival (P = 0.025) and overall survival (P = 0.008). Single-cell RNA sequencing revealed that the tumor microenvironment of the Fibrosis+ LM was characterized by T cells with an exhausted phenotype, macrophages displaying a profibrotic and suppressive phenotype and fibrosis-promoting fibroblasts. Further investigation highlighted the pivotal role of VCAN_eCAF in remodeling the tumor fibrosis in the tumor microenvironment of Fibrosis+ LM, emphasizing potential targetable interactions such as FGF23 or FGF3-FGFR1. Validation through multiplex immunohistochemistry/immunofluorescence and spatial transcriptomics supported these findings. Here we present a comprehensive single-cell atlas of tumor fibrosis in LM, revealing the intricate multicellular environment and molecular features associated with it. These insights deepen our understanding of tumor fibrosis mechanisms and inform improved clinical diagnosis and treatment strategies. Show less

Tumorigenesis is typically accompanied by cellular dedifferentiation and the acquisition of stem cell-like attributes. However, few studies have comprehensively evaluated the putative relationships between these characteristics and various cancers. Here, we integrated gene expression and DNA methylation quantitative trait loci (cis-eQTL and cis-mQTL) data from the blood to perform multi-omics Mendelian randomization analysis. Our analyses revealed 967 stem cell-associated genes (P < 0.05) and 11,262 methylation sites (P < 0.01) significantly related to 12 cancers. SMAD7 (cg14321542) in colon cancer, IGF2 (cg13508136) in prostate cancer, and FADS1 (cg07005513) in rectal cancer were prioritized as candidate causal genes and regulatory elements. Notably, using cis-eQTL data from the corresponding tissue sites, we detected 16 stem cell-associated genes dramatically causally associated with six cancers (FDR<0.2). The gene THBS3 was particularly common in both blood and stomach tissues and exhibited prognostic significance. Furthermore, it was markedly associated with one microbial metabolic pathway and four immunophenotypes. Functional validation using the ECC12 gastric cancer cell line revealed that the inhibition of its expression could accelerate oxidative phosphorylation and reactive oxygen species production, reduce clonal proliferation ability, and promote the apoptosis of stomach tumor cells. Additionally, based on spatial transcriptomic data from gastrointestinal cancers, the results demonstrated the clusters enriched with the most stem cell-associated genes exhibited significantly enhanced tumor-promoting potency, and the THBS3-expressing cells displayed suppressed oxidative phosphorylation. Overall, this study enhances our understanding of tumorigenic mechanisms and aids in the identification of therapeutic targets. Show less

Alzheimer's disease (AD) presents significant challenges due to its intricate pathogenic mechanisms and the limited efficacy of single-target therapies. In this study, we investigated the potential of chlorogenic acid (CHA), a multifunctional natural active compound, in AD therapy by developing a trifunctional nanocarrier (MC-H/R/si). CHA was effectively conjugated with iron-based metal-organic frameworks (MIL/Fe-100) through chelation interaction.

Breast cancer (BRCA) is a prevalent malignant tumor among women, and the use of anesthetic drugs during surgical resection may influence tumor biology and patient prognosis. This study aimed to identify prognostic biomarkers associated with dexmedetomidine and dezocine (DD) in BRCA patients. Through Mendelian Randomization analysis, we screened four DD targets that had a causal relationship with BRCA. Subsequently, utilizing TCGA-BRCA data, univariate and Lasso Cox analyses revealed two significant prognostic biomarkers (NR1H3 and ADRB1) associated with BRCA patient prognosis, leading to the successful construction and validation of a prognostic risk model. Kaplan-Meier survival curves indicated that patients with higher NR1H3 and ADRB1 expression had longer overall survival (OS). Immunoinfiltration analysis showed that high-risk group patients exhibited increased infiltration levels of CD56 bright natural killer cells, CD56 dim natural killer cells, eosinophils, and plasmacytoid dendritic cells. Conversely, activated B cells and immature B cells demonstrated greater infiltration in the low-risk group. Correlation analysis revealed significant associations between prognostic biomarkers and various immune cells, including CD56 bright natural killer cells, CD56 dim natural killer cells, and activated CD8 T cells. NR1H3 was highly positively correlated with immune checkpoints such as TIGIT, PDCD1, CD274, CTLA4, LAG3, and HAVCR2 (|cor|≥0.3, The online version contains supplementary material available at 10.1007/s12672-025-03694-7.

Diabetic retinopathy (DR) is the main cause of blindness worldwide, and its prevalence rate is constantly rising. More in-depth exploration of its risk factors and pathogenic mechanisms is needed. This study systematically identified potential therapeutic targets for DR by evaluating causal effects of 16,989 genes and 2,923 proteins on DR/subtypes via two-sample Mendelian randomization (MR), validated with colocalization/Summary-data-based Mendelian randomization (SMR). National Health and Nutrition Examination Survey (NHANES) 1999-2010 cross-sectional data (weighted logistic/Restricted cubic spline (RCS)) pinpointed key risk factors; MR explored their links to DR subtypes. Bioinformatics (bulk and single-cell transcriptomics) analyzed molecular mechanisms of shared targets (gene expression, immune infiltration, pathway enrichment). Machine learning selected key targets for models. Finally, two-step mediation MR examined how targets regulate DR via risk factors. This study identified 64 core targets with causal links to DR. Subtype analysis revealed 2,128 causal genes and subtype-specific targets (e.g. 52 for background DR, 66 for proliferative DR). SMR validated these findings. NHANES data highlighted body mass index (BMI), stroke, hypertension (HBP), and C-reactive protein (CRP) as key DR risk factors, confirmed by MR. Transcriptomics identified 29 differentially expressed genes associated with both risk factors and DR, linked to immune cell regulation. Machine learning selected core targets (LY9, WWP2, etc.) and built a nomogram for DR risk prediction. Functional enrichment showed these targets enriched in chemokine/cytokine and immune-inflammatory pathways. Two-step mediation MR further revealed LY9, ARHGAP1, and WWP2 influence DR subtypes via regulating BMI, CRP, and HBP. This study systematically elucidates the key risk factors, potential molecular mechanisms, and core regulatory targets of DR through multi-omics integration, causal inference, and bioinformatics approaches. The results indicate that inflammation, immune dysregulation, and metabolic disorders play crucial roles in the pathogenesis of DR. Key genes such as LY9, ARHGAP1, and WWP2 could serve as potential intervention targets, offering theoretical foundations and strategic support for early warning and precision treatment of DR.

The gut microbiota influences host immunity and metabolism, and changes in its composition and function have been implicated in several non-communicable diseases. Here, comparing germ-free (GF) and specific pathogen-free (SPF) mice using spatial transcriptomics, single-cell RNA sequencing, and targeted bile acid metabolomics across multiple organs, we systematically assessed how the gut microbiota's absence affected organ morphology, immune homeostasis, bile acid, and lipid metabolism. Through integrated analysis, we detect marked aberration in B, myeloid, and T/natural killer cells, altered mucosal zonation and nutrient uptake, and significant shifts in bile acid profiles in feces, liver, and circulation, with the alternate synthesis pathway predominant in GF mice and pronounced changes in bile acid enterohepatic circulation. Particularly, autophagy-driven lipid droplet breakdown in ileum epithelium and the liver's zinc finger and BTB domain-containing protein (ZBTB20)-Lipoprotein lipase (LPL) (ZBTB20-LPL) axis are key to plasma lipid homeostasis in GF mice. Our results unveil the complexity of microbiota-host interactions in the crosstalk between commensal gut bacteria and the host. Show less

Lipid metabolism abnormalities and inflammation have been implicated in gallstone disease (GSD) development, but the causal relationships and potential mediation effects among lipid metabolites, inflammatory factors, and GSD remain unclear. The aim of this study is to explore the causal relationships among these 3 factors. This study employed 2-sample Mendelian Randomization (TSMR) and 2-step MR to investigate the causal relationships and potential mediation effects among 91 inflammatory factors, 6 lipid metabolism-related molecules (HDL-C, LDL-C, TG, total cholesterol, ApoA1, and ApoB), and GSD. We opted for 4 distinct MR analysis methods including inverse variance weighted method, weighted median method, MR-Egger regression method and MR-PRESSO analysis. Sensitivity analyses included MR-Egger intercept tests, Cochran's Q statistic, Steiger tests, and leave-one-out analyses. Product of coefficients method was used to estimate mediation proportion. TSMR analysis revealed that every 1-unit increase in low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB), the risk of GSD decreased by 16.5%, 10.2%, 8.4%, and 13.1%, respectively. Inflammatory factors such as Natural killer cell receptor 2B4 (CD244), Macrophage colony-stimulating factor 1 (CSF-1), and interleukin-18 receptor 1 (IL-18R1) were identified as risk factors for GSD, while Fibroblast growth factor 19 levels (FGF19), Interleukin-1-alpha levels (IL-1α), and Interleukin-8 levels (IL-8) were found to be protective. Mediation analysis through 2-step MR identified potential pathways involving ApoA1--IL-8--GSD (P = .084) and IL-1α--ApoB--GSD (P = .117). This study provides robust evidence of causal links between specific lipid metabolites and GSD, as well as suggestive causal associations for several inflammatory factors. However, mediation analysis did not support significant roles for lipids or inflammatory factors as mediators in GSD pathogenesis. Future research could be further pursued in areas such as drug target intervention and mechanistic studies. Show less

Sleep disorders show comorbidity with depression and Alzheimer's disease (AD), especially in ageing. However, the neuroimmunological role of sleep deprivation (SD) as possible inducer to these conditions remains unknown. Omega-3 fatty acids (n-3 FAs) can improve depression and AD through anti-inflammation, up-regulating neurotrophins and normalizing neurotransmitters, while their therapeutic effects on sleep deprivation (SD)-induced changes in different ages requires investigation. Adult and old Fat-1 (converting n-6 to n-3 FAs) and wild-type (WT) mice were subjected to chronic SD. After behavioral evaluation, brain FAs, monoamine neurotransmitters, circadian-gene expression, TLR-4 signaling-pathway, glial polarization, cytokine profile, and AD-related markers were analyzed using GC-MS, HPLC, qPCR, ELISA and western-blotting. Furthermore, bioinformatic analysis evaluated SD-related networking with depression and AD. SD induced anxiety, anhedonia, despair, and memory impairments. The n-3:n-6 ratio, BMAL-1 gene expression, and melatonin concentration were decreased, whereas corticosterone, TLR-4, GSK3β, and NFκB concentrations increased in SD groups compared to the controls. Increased IBA-1 protein expression and proinflammatory IL-1β, TNF-α, and IL-6 concentrations were associated with decreased monoamine neuro-transmitter levels in SD groups. APP, BACE-1, RAGE and APPβ concentrations were increased, whereas LRP-1 and APPα concentrations and the APPα/APPβ ratio were decreased in SD groups than controls. These changes were more pronounced in old WT and Fat-1 animals than adults. However, compared to WT-SD, these changes were significantly ameliorated in Fat-1-SD mice, but recovery was less pronounced in old Fat-1. SD-induced neuroinflammation and impaired APP processing may contribute to behavioral impairments, which exacerbated with age. Although n-3 FAs significantly ameliorated SD-induced adverse behavioral and neuroimmunological changes, this therapeutic effect was markedly reduced in old animals. Show less

In Traditional Chinese Medicine (TCM), dampness is a pathogenic factor arising from impaired production and transportation of bodily fluids. While Fuling Zexie decoction (FLZXD) has demonstrated therapeutic efficacy in dampness constitution (DC) treatment, the material basis underlying its constitutional modulatory effects remains unclear. This study proposes objective indicators for the differentiation and therapeutic evaluation of DC and elucidates the material basis of FLZXD in DC treatment. Serum exosome proteomic profiling was conducted across two independent cohorts to identify DC-related indicators and assess the therapeutic efficacy of FLZXD in DC-associated hyperlipidemia (DC-hyperlipidemia). The bioactive compounds of FLZXD were prioritized through a comprehensive analysis of patent documentation and network pharmacology, with subsequent validation of DC-related targets using enzyme-linked immunosorbent assay (ELISA). Proteomic analysis of serum exosomes revealed signatures that differentiate individuals with a balanced constitution (BC) from those with DC. The differentially expressed proteins (DEPs) were enriched predominantly in pathways related to the complement cascade and cardiovascular diseases. FLZXD demonstrated therapeutic efficacy against DC-hyperlipidemia, as evidenced by the reversal of DEPs expression following treatment, which was supported by the patentable findings and network pharmacology analysis. Through experimental validation and pharmacological evidence, the active herbs of FLZXD (Fuling, Zexie and Baizhu, collectively referred to as FZB) were identified, and a total of 73 putative therapeutic targets involved in the dampness-resolving effects of FZB were revealed. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment further confirmed that FLZXD exerts its anti-dampness effects primarily through regulation of the complement and coagulation cascades. Among eight candidate indicators specifically associated with DC, four proteins were validated via ELISA, indicating potential utility for the differentiation of DC. The sensitivity (%), specificity (%), fold change (FC), p-value, and area under the curve (AUC) for each indicator were as follows: apolipoprotein B-100 (APOB) (100.00, 80.00, 0.63, 0.0051, 0.94), complement factor H-related protein 1 (CFHR1) (90.00, 100.00, 0.55, 0.0001, 0.98), alpha-1-acid glycoprotein 1 (ORM1) (100.00, 80.00, 0.71, 0.0043, 0.92), and pigment epithelium-derived factor (SERPINF1) (90.00, 70.00, 0.66, 0.0002, 0.87). The integrative approach, combining proteomic profiling, network pharmacology analysis, and clinical validation, establishes an integrative approach for research on TCM constitutions. This approach provides (1) molecular insights into the differentiation of DC, (2) a foundation for mechanism-based, targeted therapeutic strategies, and (3) enhanced patient stratification to support personalized treatment approaches.

Background Myeloid/lymphoid neoplasm with eosinophilia and rearrangement of FGFR1(MLN-FGFR1), also referred to as 8p11 myeloproliferative syndrome (EMS), arises from aberrant FGFR1 gene rearrangement in bone marrow hematopoietic stem cells, resulting in the transformation of myeloid/lymphoid cells into neoplastic growths. The clinical and laboratory features of affected individuals are influenced by the specific partner genes. Purpose This article aims to report a case of MLN-FGFR1 involving a novel CNTRL::FGFR1 splicing variant and to discuss its clinicopathological characteristics and treatment challenges. Methods/Results We report a case of MLN-FGFR1 in a 35-year-old male patient presenting with leukocytosis, lymphadenopathy, hepatosplenomegaly, and a mixed population of B lymphoblasts, T lymphoblasts, and monoblasts in the bone marrow and lymph nodes. Comprehensive molecular profiling, including chromosomal karyotyping, fluorescence in situ hybridization (FISH), targeted transcriptome sequencing, reverse transcription polymerase chain reaction (RT-PCR), and Sanger sequencing, identified a novel splicing variant of the CNTRL::FGFR1 fusion, resulting from a t(8;9)(p11;q33) translocation. This novel splicing variant involves an in-frame fusion between exon 38 of CNTRL and exon 11 of FGFR1, retaining the kinase domain of FGFR1 and leading to its constitutive activation. Despite multiple treatment regimens, the patient failed to achieve complete remission (CR). Conclusion The findings highlight the urgent need for targeted therapies, such as FGFR inhibitors, to improve outcomes in patients with FGFR1-rearranged malignancies. Show less

Alzheimer's disease (AD) is a neurodegenerative disease characterized by abnormal accumulation of β-amyloid (Aβ) and hyperphosphorylation of the Tau protein. Currently, there is a lack of effective and safe therapeutic approaches. In Traditional Chinese medicine (TCM), Gandou Decoction has shown significant efficacy in improving cognitive decline and dementia-related symptoms, but its specific mechanism remains unclear. This study systematically analyzed the active components and anti-AD mechanism of Modified Gandou Decoction (MGD) by integrating network pharmacology, machine learning, molecular docking, molecular dynamics (MD) simulation, and A total of 21 potential active molecules of MGD and 68 intersection targets were screened out. Among them, 8 core targets (EIF2AK2, PPARG, BACE1, ESR1, GSK3B, ACE, CASP3, MAPK14) were confirmed to be significantly associated with AD pathology by gene expression difference analysis (P ≤ 0.05). KEGG enrichment analysis showed that MGD mainly intervenes in the amyloid production pathway, the MAPK pathway, and the IL-17 pathway. Molecular docking demonstrated that the majority of the 21 potential active compounds exhibited strong binding affinities to the 8 core targets. Moreover, some potential active molecules exhibited better binding energy and similar binding modes compared with known inhibitors when binding to the corresponding target proteins. Molecular dynamics simulation showed that Alisol B, a potential active component of MGD, could stably bind to BACE1, EIF2AK2, and CASP3. MGD exerts its anti-AD effect through its potential active component Alisol B, which binds to target proteins BACE1, EIF2AK2, and CASP3, and synergistically inhibits Aβ production, Tau phosphorylation, and neuroinflammatory processes through multiple pathways. This study provides a foundation for developing MGD-derived natural products for AD treatment, although the precise mechanisms require further experimental validation. Show less

Magnetic resonance imaging and circulating molecular testing are potential methods for diagnosing and treating Parkinson's disease (PD). However, their relationships remain insufficiently studied. Using genome-wide association summary statistics, we found in the general population a genetic negative correlation between white matter tract mean diffusivity and PD (-0.17 < Rg < -0.11, p < 0.05), and a positive correlation with intracellular volume fraction (0.12 < Rg < 0.2, p < 0.05). Additionally, 1345 circulating genes causally linked with white matter tract diffusivity were enriched for muscle physiological abnormalities (padj < 0.05). Notable genes, including LRRC37A4P (effect size = 15.7, p = 1.23E-55) and KANSL1-AS1 (effect size = -15.3, p = 1.13E-52), were directly associated with PD. Moreover, 23 genes were found linked with genetically correlated PD-IDP pairs (PPH4 > 0.8), including SH2B1 and TRIM10. Our study bridges the gap between molecular genetics, neuroimaging, and PD pathology, and suggests novel targets for diagnosis and treatment. Show less

Bladder cancer (BLCA) is a prevalent urological malignancy. We aim to identify novel biomarkers for BLCA and elucidate the specific regulatory mechanisms of polo-like kinase 1 (PLK1). Using differentially expressed genes (DEGs) screened from GSE38264 and GSE130598 datasets, we constructed protein-protein interaction networks to identify hub genes, whose expression was validated using reverse transcription-quantitative polymerase chain reaction. The malignant phenotype of BLCA cells was assessed by Cell Counting Kit-8, 5-ethynyl-2'-deoxyuridine, Transwell, and wound-healing assays. Hematoxylin-eosin and immunohistochemical staining were employed to evaluate BLCA development in mouse xenograft models. The protein expression was detected by Western blot. PLK1, AURKA, AURKB, CDK1, ERBB2, ERBB3, FGFR1, FYN, ABL1, and PRKDC were hub genes with predictive value for BLCA. Among them, PLK1 was selected as a key target of BLCA. PLK1 knockdown inhibited the viability, proliferation, migration, and invasion of BLCA cells. In vivo, PLK1 knockdown inhibited tumor growth. Silencing PLK1 activated the Hippo pathway in BLCA cells and tumor tissues. The Hippo pathway inhibitor reversed the inhibitory effects of PLK1 silencing on malignant phenotype of BLCA cells. PLK1 knockdown exerts an inhibitory effect on BLCA via activating the Hippo pathway, which presents promising therapeutic strategies for BLCA. Show less

Fel d1, the major cat allergen responsible for over 90% of human IgE-mediated allergies, has an incompletely defined physiological role. To explore its function and assess the feasibility of producing hypoallergenic cats, we knocked out the CH2 domain of Fel d1 using CRISPR/Cas9 in feline skin cells. An optimized sgRNA introduced a frameshift mutation, with knockout efficiency validated by sequencing, qRT-PCR, and Western blot. Transcriptomic alterations were profiled by RNA-seq, and functional consequences were investigated via GO, KEGG, and GSEA analyses. Key findings were confirmed by qPCR, and phenotypes were assessed using CCK-8, EdU, and flow cytometry. The approach successfully generated a three-base insertion, resulting in near-complete loss of CH2 mRNA and Fel d1 protein. RNA-seq identified 3,469 differentially expressed genes (DEGs), with significant enrichment in pathways for hypertrophic cardiomyopathy (HCM) and rheumatoid arthritis (RA). Key genes in these pathways (e.g., Show less

Endothelial cells (ECs) senescence has emerged as a critical factor in the pathogenesis of atherosclerosis, contributing to vascular aging and plaque formation. However, the molecular mechanisms underlying endothelial senescence in atherosclerosis remain poorly understood. Single-cell RNA sequencing (scRNA-seq) data from atherosclerotic core plaques and adjacent normal tissues were analyzed using the Seurat package to identify cell subpopulations and senescence markers. RNA-seq data from early and late atherosclerotic plaques were used for differential gene expression analysis. Subsequently, the candidate gene was identified and validated in the atherosclerotic plaques of Single-cell analysis revealed elevated levels of senescence markers in ECs within atherosclerotic plaques. Combined with bulk RNA-seq analysis, This study highlights the critical role of endothelial senescence in atherosclerosis and identifies Show less

Vascular calcification (VC), a common complication associated with diabetes mellitus (DM), substantially increases the risk of cardiovascular diseases and is associated with elevated mortality in individuals with DM. Endothelial-to-mesenchymal transition (EndMT) imparts phenotypic plasticity to vascular endothelial cells (VECs), granting them the potential for osteogenic differentiation, which is a crucial mechanism in regulating VC. Notably, adenosine-ADORA2A-mediated endothelial dysfunction plays a pivotal regulatory role in cardiovascular diseases. However, the specific role of endothelial ADORA2A in diabetic VC remains to be elucidated. In this study, we found that ADORA2A was upregulated in the endothelium of diabetic mice and cultured human aortic endothelial cells (HAECs) with high glucose treatment. Deletion of endothelial Adora2a or pharmacologic inhibition of ADORA2A with KW6002 attenuated EndMT, osteogenic differentiation, and calcium deposit in diabetic aortas of Ins2 Show less

Growth traits are among the most important economic phenotypes targeted in the genetic improvement of beef cattle. To understand the genetic basis of growth traits in Huaxi cattle, we performed a genome-wide association study (GWAS) on body weight, eye muscle area, and back fat thickness across five developmental stages in a population of 202 Huaxi cattle. Additionally, publicly available RNA-seq data from the longissimus dorsi muscle of both young and adult cattle were analyzed to identify key genes and genetic markers associated with growth in Huaxi cattle. In total, 7.19 million high-quality variant loci (SNPs and INDELs) were identified across all samples. In the GWAS, the three multilocus models (FarmCPU, MLMM, and BLINK) outperformed the conventional single-locus models (CMLM, GLM, and MLM). Consequently, GWAS analysis was conducted using multilocus models, which identified 99 variant loci significantly associated with growth traits and annotated a total of 83 candidate genes (CDGs). Additionally, 23 of the 83 CDGs overlapped with significantly differentially expressed genes identified from public RNA-seq datasets of longissimus dorsi muscle between young and adult cattle. Furthermore, gene functional enrichment (KEGG and GO) analyses revealed that over 30% of the pathways and GO terms were associated with muscle development and fat deposition, crucial factors for beef production. Specifically, key genes identified included Show less

Chronic kidney disease (CKD) is highly prevalent, incurable, and lacks effective treatments. Aging is closely linked to various kidney diseases. In this study, we combined CKD and aging using bioinformatics approaches to identify potential anti aging drugs and therapeutic targets for CKD. We analyzed datasets GSE37171 and GSE66494 from the GEO database, identifying 317 differentially expressed genes (DEGs). By intersecting these DEGs with aging related genes, we identified 23 aging associated differential genes (ARDEGs). A protein-protein interaction (PPI) network was constructed using the STRING database, and the top 10 hub ARDEGs were identified using Cytoscape software. Potential anti aging drugs, including Cinnamaldehyde, were identified through the ceRNA and transcription factor regulatory networks, as well as the DGldb database. Among the key regulatory genes identified in CKD patient samples were SOD2, FGF21, FOS, RELA, DDIT4, BMI1, DUSP6, LGALS3, CXCR2, and CEBPB. Cinnamaldehyde and other drugs were found to target aging associated pathways, suggesting their potential to delay CKD progression through modulating these pathways. Finally, we verified the low-expression of DDIT4 and DUSP6, the two targets of Cinnamaldehyde, in unilateral ureteral obstruction (UUO) animal model. Additionally, Cinnamaldehyde was shown to reduce the expression of fibrosis markers such as fibronectin (FN) and α-smooth muscle actin (α-SMA) in HK2 cells under TGF-β1 stimulation. This study provides a foundational understanding of aging related molecular targets in CKD and offers new directions for developing anti aging therapies to treat CKD. Show less
