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

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

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. The resulting nanocomplex (MC) not only enhances the bioavailability of CHA but also facilitates a synergistic antioxidant effect between CHA and MIL/Fe-100. Importantly, CHA can chelate Zn Show less

Microcystin-LR (MC-LR) is a toxin that causes hepatic steatosis. Our previous study found that exposure to 60 μg/L MC-LR for 9 months resulted in liver lipid accumulation, but the underlying mechanisms remain elusive. Herein, for the first time, fatty acid-targeted metabolome and RNA-seq were combined to probe the effect and mechanism of chronic (12-month) MC-LR treatment on mice lipid metabolism at environmental-related levels (1, 60, and 120 μg/L). It was found that MC-LR dose-dependently raised serum and liver lipid levels. The total cholesterol (TC) levels in the liver were significantly increased following treatment with 1 μg/L MC-LR (equivalent to 0.004 μ/L in human). Treatment with 60 and 120 μg/L MC-LR significantly elevated TC and triglyceride (TG) levels in both serum and liver. Serum fatty acid-targeted metabolome analysis demonstrated that exposure to 1, 60, and 120 μg/L MC-LR caused significant alterations in the fatty acid profile. Chronic 1, 60, and 120 μg/L MC-LR treatment significantly increased serum polyunsaturated fatty acids (PUFAs), including conjugated linoleic acid and eicosapentaenoic acid, which positively correlated with serum or liver TG levels. Chronic exposure to 120 μg/L MC-LR led to a significant decrease in the accumulation of saturated fatty acids, including citramalic acid, pentadecanoic acid, and docosanoic acid, which were negatively correlated with serum or liver lipid levels. These findings suggested that 1 μg/L MC-LR exposure caused mild lipid metabolism disruption, while 60 and 120 μg/L MC-LR treatment resulted in pronounced hepatic steatosis in mice. Transcriptome analysis revealed that chronic environmental MC-LR treatment regulated the expression of genes involved in the phosphatidylinositol 3-kinase (PI3K) complex and fatty acid metabolism. Western blotting and RT-qPCR confirmed that chronic environmental MC-LR exposure activated the PI3K/AKT/mTOR signaling pathway, the downstream of 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.

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.

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

Cholesterol metabolism (CM) plays essential roles in human disease. Ulcerative colitis (UC) is a chronic inflammatory bowel disease associated with significant morbidity and healthcare burden. However, the role of CM in UC remains unclear. Gene expression data of UC patients and control samples were retrieved and merged from GSE75214, GSE92415, GSE16879, and GSE48958. Differential analysis was performed for the identification of cholesterol homeostasis-related differentially expressed genes (DEGs), followed by machine learning for cholesterol homeostasis-related hub DEGs. Five cholesterol homeostasis related genes were identified. We further assessed the related pathways of 5 hub genes. Five overlapped cholesterol homeostasis related genes were identified by DEGs analysis. LIPC, LIPG, CETP, ABCB11, and APOH were identified as hub genes. The current study identified 5 cholesterol homeostasis related genes, LIPC, LIPG, CETP, ABCB11, and APOH, that might play key roles in the development of UC. These findings offer new insights for further exploring UC and its underlying mechanisms. Show less

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

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 recent years, accumulating evidence has highlighted the critical role of miR-627-5p in the occurrence and progression of various cancers. However, its specific role and mechanism in cervical cancer (CC) remain unclear. This study aimed to elucidate the mechanism by which miR-627-5p inhibits the malignant progression of CC and assess its potential clinical implications. In C33A cells, the mRNA expression levels of ANGPTL4 and miR-627-5p were analyzed using qRT-PCR. The miR-627-5p mimics and their control (miR-NC) were transfected into C33A cells to determine whether miR-627-5p directly regulates ANGPTL4 expression. A comprehensive suite of assays, including CCK-8, migration, transwell, flow cytometry, and Western blotting, was conducted to evaluate how miR-627-5p modulates the malignant biological behavior of CC cells. Rescue experiments were performed by overexpressing ANGPTL4. In C33A cells, miR-627-5p expression was reduced, whereas ANGPTL4 expression was elevated. Further analysis confirmed that miR-627-5p negatively regulates ANGPTL4 by directly targeting its 3'-UTR. Functional assays demonstrated that miR-627-5p inhibits proliferation, invasion, migration, and epithelial-mesenchymal transition (EMT) while promoting apoptosis and S-phase arrest in C33A cells, effects that were reversed by ANGPTL4 overexpression. These findings highlight the potential of miR-627-5p as both a biomarker and a therapeutic target for CC. By inhibiting EMT and regulating ANGPTL4 expression, miR-627-5p may provide a novel avenue for improving therapeutic strategies, particularly in advanced or metastatic CC. Moreover, miRNA-based therapies, supported by advanced delivery systems such as nanoparticle carriers, could enhance the stability and precision of miR-627-5p applications. This study lays the groundwork for future research integrating miR-627-5p into precision medicine approaches for CC treatment. Show less

This study aimed to investigate the expression and clinical significance of interleukin-27 (IL-27) and forkhead box P3 (Foxp3) in oral squamous cell carcinoma (OSCC) tissues, analyze their co-expression correlations, and explore their potential as prognostic biomarkers and therapeutic targets for OSCC. Immunohistochemistry (IHC) was used to detect the expression of the two subunits of IL-27, IL-27p28 and Epstein-Barr virus-induced gene 3 (EBI3), and Foxp3 in OSCC tissues and normal tissues. Chi-square test was used to analyze the correlation between the expression of the three in OSCC tissues and the clinical pathological parameters of patients. The IHC results showed that the expressions of IL-27p28, EBI3 and Foxp3 proteins in OSCC tissues were all higher than those in normal control tissues( The expression levels of IL-27p28, EBI3 and Foxp3 in OSCC tissues are significantly upregulated, indicating that the three play important roles in the occurrence and development of OSCC tumors. Furthermore, its high expression is associated with various clinicopathological characteristics of OSCC patients and can be used as a potential indicator for evaluating the prognosis of OSCC patients.

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.

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

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

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

Fatty Acid Desaturase 1 (FADS1) is a rate-limiting enzyme controlling the bioproduction of long-chain polyunsaturated fatty acids (PUFAs). Increasing studies suggest that FADS1 is a potential cancer target. Our previous research has demonstrated the significant role of FADS1 in cancer biology and patient survival, especially in kidney cancers. We aim to explore the underlying mechanism in this study. We found that pharmacological inhibition or knockdown of the expression of FADS1 significantly reduced the intracellular conversion of long-chain PUFAs, effectively inhibits renal cancer cell proliferation, and induces cell cycle arrest. The stable knockdown of FADS1 also significantly inhibits tumor formation in vivo. Mechanistically, we showed that while FADS1 inhibition induces endoplasmic reticulum (ER) stress, FADS1 expression is augmented by ER-stress inducer, suggesting a necessary role of PUFA production in response to ER stress. FADS1-inhibition sensitized cellular response to ER stress inducers, leading to cell apoptosis. Also, FADS1 inhibition-induced ER stress leads to activation of the PERK/eIF2α/ATF4/ATF3 pathway. Inhibiting PERK or knockdown of ATF3 rescued FADS1 inhibition-induced ER stress and cell growth suppression, while ATF3-overexpression aggravates the FADS1 inhibition-induced cell growth suppression and leads to cell death. Metabolomic analysis revealed that FADS1 inhibition results in decreased level of UPD-N-Acetylglucosamine, a critical mediator of the unfolded protein response, as well as impaired biosynthesis of nucleotides, possibly accounting for the cell cycle arrest. Our findings suggest that PUFA desaturation is crucial for rescuing cancer cells from persistent ER stress, supporting FADS1 as a new therapeutic target. Show less

Gastroesophageal reflux disease (GERD) and asthma are commonly co-occurring conditions, with shared genetic factors identified. However, the specific loci and the influence of common genetic architecture remain undefined. We obtained genome-wide association study (GWAS) summary statistics for GERD (71 522 cases and 261 079 controls) and asthma (56 167 cases and 352 255 controls). Using linkage disequilibrium score regression (LDSC), we assessed genetic correlations between GERD and asthma. Bidirectional Mendelian randomization (MR) was performed to investigate potential causal relationships, followed by cross-trait GWAS meta-analysis and colocalization analysis to identify shared risk loci. Additionally, summary-data-based MR and transcriptome-wide association study were conducted to pinpoint common functional genes. Finally, we analyzed gene expression profiles in both healthy individuals and GERD patients using esophageal single-cell RNA sequencing (scRNA-seq) data. We identified a significant genetic correlation between GERD and asthma ( rg = 0.37, P = 6.19 × 10 -38 ) and a significant causal effect of GERD on asthma [odds ratio (OR) = 1.22, P = 1.54 × 10 -5 ]. Cross-trait meta-analyses revealed 56 shared risk loci between GERD and asthma, including 51 loci that were newly identified. Three loci (rs61937247, rs7960225, and rs769670) exhibited evidence of colocalization. Gene-level analyses pinpointed three novel shared genes ( RBM6, SUOX , and MPHOSPH9 ) between GERD and asthma. scRNA-seq analysis uncovered heightened expression of these genes in immune cells of patients diagnosed with GERD. Our study has discovered novel shared genetic loci and candidate genes between GERD and asthma, providing further insights into the genetic susceptibility of comorbidity and potential mechanisms of the two diseases.

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

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

This study aimed to investigate the effects of a diet supplemented with different levels of oleic acid (OA) on growth performance, serum biochemical parameters, nutrient utilization, and intestinal lipid metabolism in Pekin ducks. A total of 350 fourteen-d-old male ducks were randomly assigned to the following five isonitrogenous and heteroenergetic dietary treatment groups: 0.00% (control), 0.25%, 0.50%, 0.75%, and 1.00% OA groups. The experiment lasted 28 days. The findings indicated that neither growth performance nor nutrient utilization was affected by OA supplementation (P > 0.05). The 0.50% OA group displayed the lowest serum triglyceride (TG) levels among all treatment groups, with significantly lower values compared to both the 0.25%=% and 0.75% OA groups (P < 0.05). Moreover, the activities of lipid droplet (LD)-degrading enzymes in the jejunal mucosa, such as adipose triglyceride lipase (ATGL), showed a significant inverse linear relationship (P < 0.05); carboxylesterase 2 (CES2) activity exhibited a proportional dose-dependent increase (P < 0.05); and lysosomal acid lipase (LAL) activity was negatively correlated with the increased concentration of OA in the diet (P < 0.05). Moreover, the mRNA expression levels of the LD formation-related genes PLIN2 were significantly higher in the 0.50% OA group compared to the 0.25% and 0.75% OA groups (P < 0.05). The mRNA expression of LD degradation-related genes, the PNPLA2 expression in the 0.25%, 0.50%, and 0.75% OA groups and LPL expression in all OA groups were downregulated (P < 0.05) when compared with those in the control group. These results suggested that dietary supplementation with OA, especially at a level of 0.50%, may decrease the serum TG content and promote lipid deposition in the jejunum in Pekin ducks by regulating the formation and degradation of enterocyte LDs.
