Ershen Wan (ESW), a classic traditional Chinese medicine (TCM) prescription composed of Psoralea corylifolia Linn. and Myristica fragrans Houtt., has been applied to treat gastrointestinal disorders in clinical practices for thousands of years. However, its potential molecular mechanism in alleviating ulcerative colitis (UC) remains to be elusive. The purpose of the study is to explore the underlying mechanism of ESW in treating UC. The protective effect of ESW on dextran sodium sulfate (DSS)-induced UC mice was assessed by body weight, disease activity index (DAI), colon length, colon tissue pathology, and colonic inflammatory factors. Furthermore, network pharmacology was applied to dissect the possible targets and biological pathways regulated by ESW. The plasma and fecal metabolomics were comprehensively analyzed by UPLC-Q-TOF/MS. Subsequently, an efficient and feasible approach integrating network pharmacology, metabolomics, and molecular docking was used to explore the key targets obtained from the metabolite-reaction-enzyme-gene network. And the effect of ESW on the MAPK signaling mediated intestinal epithelial cell apoptosis was further investigated by in vitro and in vivo experiments. ESW could notably alleviate colon injury and inflammation of UC mice. Network pharmacology suggested that the bioactive components of ESW could mainly modulate signaling pathways associated with inflammation and metabolism. Consistently, plasma and fecal metabolomics further indicated that ESW could regulate the metabolic pathways of arachidonic acid, linoleic acid, sphingolipid, tryptophan, and glycerophospholipid. And the combined analysis of network pharmacology and metabolomics revealed that 14 pivotal targets were modulated by ESW, including PTGS1, PTGS2, CYP1A1, FADS1, CBR1, ALOX5, EPHX1, EPHX2, HPGD, PLA2G1B, PLA2G7, MGLL, ACHE, and SPHK1. Additionally, molecular docking suggested that bioactive components of ESW could bind well to these potential targets. And in vitro and in vivo experiments further verified that ESW could markedly ameliorate pathological symptoms of UC mice through inhibiting MAPK signaling mediated colonic epithelial cell apoptosis. Collectively, these findings indicated that ESW could effectively alleviate the pathological symptoms of UC mice, mainly involving in the modulation of lipid and amino acid metabolism pathways, and the suppression of MAPK signaling-mediated apoptosis. In this study, the potential mechanism of ESW for the treatment of UC was first clarified, which provided a solid scientific foundation for its clinical application. Notably, the proposed strategy facilitated a comprehensive prediction and validation of the efficacy and molecular mechanism of TCMs, and also provided a novel approach for revealing the intricate biological pathogenesis of diseases.

Glucagon-like peptide-1 receptor (GLP1R) agonists and glucose-dependent insulinotropic polypeptide receptor (GIPR) agonists may help treat metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH). However, their definitive effects are still unclear. Our study aims to clarify this uncertainty. We utilised conventional Mendelian randomisation (MR) analysis to explore potential causal links between plasma GLP-1/GIP concentrations and MASLD and its related traits. Next, we conducted drug-target MR analysis using highly expressed tissue data to assess the effects of corresponding drug perturbation on these traits. Finally, mediation analysis was performed to ascertain whether the potential causal effect is direct or mediated by other MASLD-related traits. Circulating 2-h GLP-1 and GIP concentrations measured during an oral glucose tolerance test showed hepatoprotective effects on MASLD risk (OR GLP-1/GIP receptor agonists offer promise in lowering MASLD/MASH risk. GIP receptor agonists can exert direct and indirect effects on MASLD mediated by weight reduction or glycemic control improvement. Show less

Precise differential diagnosis between lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (LPL/WM) and marginal zone lymphoma (MZL) remains a challenging issue because of overlapping clinicopathological and immunophenotypic features. In the present study, the differential diagnostic potential of CD180 was assessed by determining its expression patterns in patients with MZL and LPL/WM through flow cytometry. The results indicated that LPL/WM cases exhibited a complete absence of CD180 expression on malignant B cells, whereas MZL cases showed robust CD180 expression (P < .001). Receiver operating characteristic analysis demonstrated that CD180 expression percentage showed optimal diagnostic accuracy in LPL/WM and MZL cases (area under the curve = 0.998, sensitivity = 100%, and specificity = 98.0%), with a further improvement in differentiation potential by the CD180 mean fluorescence intensity ratio (lymphocytes/monocytes) of ≤ 0.47 (area under the curve = 0.937).

This study aimed to elucidate the bidirectional causal relationships between Alzheimer's disease (AD), cerebral small vessel disease (CSVD), and the effect of inflammatory cytokines on AD and CSVD using Mendelian randomization (MR). We employed publicly available summary-level data from genome-wide association studies for AD, CSVD, and 91 inflammatory cytokines. Genetic variants strongly associated with each risk factor were selected as instrumental variables. The inverse variance weighted (IVW) method was primarily used for causal inference, with sensitivity analyses including MR-Egger and weighted median estimators. MR analysis revealed that genetically predicted CSVD significantly increased the risk of AD (odds ratio [OR] = 1.035, 95% CI, 1.015-1.056, P = 0.001). Conversely, AD did not significantly influence CSVD risk (OR = 0.878, 95% CI, 0.701-1.100, P = 0.257). Among inflammatory cytokines, Axin1 (OR = 1.082, 95% CI, 1.009-1.159, P = 0.026) and bNGF (OR = 1.061, 95% CI, 1.001-1.125, P = 0.048) increased AD risk, while CD5 (OR = 0.937, 95% CI, 0.887-0.991, P = 0.022) and CXCL11 (OR = 0.951, 95% CI, 0.912-0.992, P = 0.019) decreased AD risk. FGF19 (OR = 0.560, 95% CI, 0.405-0.773, P < 0.001) and TNFSF14 (OR = 0.744, 95% CI, 0.580-0.954, P = 0.020) were protective against CSVD. Our findings suggest that CSVD may increase AD risk, while specific inflammatory cytokines exhibit differential associations with these conditions. Targeting vascular health and inflammation may offer promising therapeutic avenues for managing neurodegenerative diseases. Show less

Enhancer of zeste homolog 2 (EZH2), a histone methyltransferase that catalyzes the trimethylation of histone H3 at lysine 27 (H3K27me3), has been implicated in promoting renal fibrogenesis. Nevertheless, its precise role and underlying mechanisms remain incompletely defined. To investigate the role of EZH2 in partial epithelial-mesenchymal transition (pEMT) and renal fibrosis, we utilized a mouse model with renal tubular cell-specific EZH2 deletion and administered gambogic acid (GA), a selective EZH2 degrader, following unilateral ureteral obstruction (UUO). In vitro, mouse renal epithelial cells were stimulated with TGF-β1 and treated with either EZH2-specific siRNA or GA to assess the effects on EMT and Notch1/3 signaling. In addition, chromatin immunoprecipitation (ChIP) assays were conducted to evaluate the binding of EZH2 and H3K27me3 to the promoters of Notch1 and Notch3. Compared with wild-type controls, mice with tubular cell-specific EZH2 deletion exhibited significantly reduced renal fibrosis, characterized by decreased expression of fibronectin, collagen III, vimentin, and Snail, while preserving E-cadherin levels in injured kidneys. Pharmacological degradation of EZH2 with GA produced comparable antifibrotic effects. UUO injury markedly upregulated Notch1, Notch3, the Notch intracellular domain, Hes1, Hey2, and Jagged-1; these increases were significantly suppressed by either EZH2 deletion or GA treatment. Similarly, in vitro, GA or EZH2-specific siRNA inhibited the expression of Notch signaling molecules in TGF-β1-treated renal epithelial cells. Chromatin immunoprecipitation analyses revealed direct binding of EZH2 and H3K27me3 to the Notch1 and Notch3 promoters. UUO injury enhanced EZH2 binding while reducing H3K27me3 enrichment at these sites, effects reversed by GA treatment. These findings demonstrate that epithelial EZH2 contributes to pEMT in renal tubular cells and promotes renal fibrosis, at least in part through activation of Notch signaling. Targeting EZH2 may hold potential as a therapeutic approach for chronic kidney disease. Show less

Lymphoplasmacytic lymphoma (LPL) represents a rare, indolent form of B-cell neoplasm, with non-immunoglobulin M subtypes, including the immunoglobulin G (IgG)-λ variant, being notably uncommon. In this report, we document a case of LPL distinguished by the presence of monoclonal IgG-λ immunoglobulin and free λ light chains, alongside its distinctive molecular characteristics and therapeutic outcomes. A 58-year-old male presented with fatigue, leukocytosis (75.45 × 109/L, 88.8% lymphocytes), lymphadenopathy, and splenomegaly. Serum studies detected an IgG-λ monoclonal protein (6.74 g/L) with concurrent elevation of free λ light chains. Bone marrow biopsy revealed marked hypercellularity, with lymphocytes comprising 80% of nucleated cells (predominantly plasmacytoid lymphocytes) and 5% plasma cell clusters. Genetic testing identified mutations in MYD88, CXCR4, and IGHV, along with trisomy 12 and del(13q14). He was diagnosed with LPL with IgG-λ monoclonal immunoglobulin and free λ light chains, classified as low risk per the Revised International Prognostic Scoring System. The patient received 3 cycles of bendamustine plus rituximab therapy. The blood cell count returned to normal and the spleen and lymph nodes were significantly reduced. Serum M protein levels decreased, and no obvious increase in B lymphocytes or plasma cells was found in the bone marrow. The patient achieved partial remission. This case highlights the diagnostic and therapeutic challenges associated with the IgG-λ subtype of LPL, an uncommon variant of this rare malignancy. This report provides valuable insights into the clinical presentation, pathological features, molecular alterations, and treatment outcomes of this rare disease. Show less

To identify latent profiles of demoralization among older adults with disabilities, analyze their influencing factors, and examine their associations with active aging. From February to July 2025, a convenience sample of 411 older adults with disabilities was recruited from a tertiary hospital in Anhui Province, China. Data were collected using a general information questionnaire, the Chinese version of the Demoralization Scale, and the Active Aging Scale. Latent profile analysis (LPA) was performed based on demoralization subscale scores. Univariate and multinominal analyses were employed to investigate the influencing factors, and the Kruskal-Wallis The prevalence of demoralization syndrome was 49.1%. LPA identified three distinct profiles: the Well-Adapted Group (53.3%), the Disheartened-Helpless Group (23.8%), and the Fully Demoralized Group (22.9%). The Kruskal-Wallis Nearly half of the older adults with disabilities experienced demoralization, with heterogeneous subgroups identified. The active aging status of demoralized subgroups requires urgent attention. These findings suggest the need for targeted interventions tailored to the characteristics of each profile to improve mental health and promote active aging in this population. 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

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

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

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

Percutaneous coronary intervention (PCI) is a practical and effective method for treating coronary heart disease (CHD). This study aims to explore the influencing factors of major cardiovascular events (MACEs) and hospital readmission risk within one year following PCI treatment. Additionally, it seeks to assess the clinical value of Apolipoprotein B/Apolipoprotein A-I (ApoB/ApoA-I) in predicting the risk of one-year MACEs and readmission post-PCI. A retrospective study included 1938 patients who underwent PCI treatment from January 2010 to December 2018 at Shandong Provincial Hospital affiliated with Shandong First Medical University. Patient demographics, medications, and biochemical indicators were recorded upon admission, with one-year follow-up post-operation. Univariate and multivariate Cox proportional hazards regression models were utilized to establish the relationship between ApoB/ApoA-I levels and MACEs/readmission. Predictive nomograms were constructed to forecast MACEs and readmission, with the accuracy of the nomograms assessed using the concordance index. Subgroup analyses were conducted to explore the occurrence of MACEs and readmission. We observed a correlation between ApoB/ApoA-I and other lipid indices, including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) (P < 0.001). Univariate and multivariate Cox regression analyses demonstrated that ApoB/ApoA-I is an independent risk factor for MACEs in post-PCI patients (P = 0.038). Within one year, the incidence of MACEs significantly increased in the high-level ApoB/ApoA-I group (ApoB/ApoA-I ratio ≥ 0.824) (P = 0.038), while the increase in readmission incidence within one year was not statistically significant. Furthermore, a nomogram predicting one-year MACEs was established (Concordance Index: 0.668). Subgroup analysis revealed that ApoB/ApoA-I was associated with the occurrence of both MACEs and readmission in male patients, those using CCB/ARB/ACEI, those without multivessel diseases, or those with LDL-C < 2.6 mmol/L. The ApoB/ApoA-I ratio serves as an independent risk factor for one-year MACEs in post-PCI patients and correlates closely with other blood lipid indicators. ApoB/ApoA-I demonstrates significant predictive value for the occurrence of MACEs within one year.Trial registration Chinese clinical trial registry: No.ChiCTR22000597-23. Show less

Little is known about the association between physical activity and the risk of pre-sarcopenic obesity (pre-SO) among adolescents. Hence, this study aimed to examine the association between physical activity and pre-SO in a sample of 2143 adolescents aged 12 to 18 years from Yinchuan, China. The pre-SO was defined by three criteria: low skeletal muscle mass adjusted by weight (SMM/W) combined with body mass index (BMI), fat mass percentage (FMP), and waist circumference (WC). After adjusting for age, smoking, drinking, sleep time, and high-fat food consumption, participants with high physical activity (HPA) had a lower risk of pre-SO compared to those with low physical activity (LPA) according to the obesity criteria of FMP (OR 0.63, 95% CI, 0.48-0.83, P < 0.05), and WC (OR 0.71, 95% CI, 0.52-0.96, P < 0.05). Additionally, restricted cubic spline models showed a linear dose-response association between total physical activity (TPA) and pre-SO no matter what obesity criteria were adopted (all P overall trend < 0.05, all P non-linear > 0.50). Subgroup analyses revealed that individuals with higher TPA levels exhibited a decreased risk of pre-SO in boys according to the obesity criteria of FMP, and WC. In conclusion, HPA is associated with a reduced risk of pre-SO in adolescents, especially among boys. Show less

This study aimed to investigate sex-specific prognostic differences between Lp(a) and CACS in ASCVD risk. We analyzed 4651 participants from the Multi-Ethnic Study of Atherosclerosis, grouped by sex. Multivariable Cox regression analysis was performed to evaluate the prognostic value of Lp(a) and CACS for ASCVD risk in both sexes. The predictive performance of these factors was compared in men and women. During a median follow-up of 13.84 years, 465 ASCVD events were recorded (272 in men and 193 in women). Multivariable Cox regression analysis revealed that both elevated Lp(a) and CACS were independent predictors of ASCVD risk in both sexes. The C-index analysis demonstrated that CACS provided incremental prognostic value over Lp(a) in men (C-index: 0.732 versus 0.714; Although both Lp(a) and CACS independently predict ASCVD risk in both sexes, the predictive value of Lp(a) varies significantly between men and women across different CACS categories.

Coronary artery disease (CAD) is increasingly recognized as a chronic inflammatory condition. Interleukin-27 (IL-27), a cytokine from the IL-12 and IL-6 families, plays a dual role in CAD pathogenesis. It exacerbates disease by interacting with IL-1β and activating the NLRP3 inflammasome, promoting inflammation and tissue damage. Conversely, IL-27 can delay disease progression by engaging STAT1/3 signalling, suppressing inflammation, and promoting tissue repair. Future research should focus on elucidating IL-27's specific biological functions, interactions with molecular targets, and clinical implications in CAD. This will enhance understanding of CAD and support the development of improved diagnostic and therapeutic strategies. Show less

Mild cognitive impairment (MCI) represents a heterogeneous state between normal aging and dementia, with varied transition pathways. While factors influencing MCI progression are known, their role in cognitive reversal is unclear. This study analyzed 756 Alzheimer's Disease Neuroimaging Initiative (ADNI) participants, classified as progressive MCI (pMCI, N = 272, mean age = 75.10 ± 7.34 years), reversible MCI (rMCI, N = 52, mean age = 69.94 ± 7.98 years) and stable MCI (sMCI, N = 432, mean age = 73.34 ± 7.44 years) based on 36-month follow-up. We compared demographic, lifestyle, clinical, cognitive, neuroimaging, and biomarker data across groups and developed a prediction model. Patients in the rMCI group were significantly younger and had a higher level of education compared with those in the pMCI group. Memory, general cognition, daily functional activities, and hippocampal volume effectively distinguished all three groups. In contrast, Aβ, tau, and other brain regions were able to distinguish only between progressive and non-progressive cases. Informant-reported Everyday Cognition (Ecog) scales outperformed self-reported Ecog scales in differentiating subtypes and predicting progression. Multinomial regression revealed that higher education, larger hippocampal volume, and lower daily functional impairment were associated with reversion, whereas Show less

Oocyte maturation-coupled mRNA post-transcriptional regulation is essential for the establishment of developmental potential. Previously, oocyte mRNA translation efficiencies focused on the trans-regulation of key RNA-binding protein (RBPs), rarely related to RNA structure. RNA G-quadruplexes (rG4s) are four-stranded RNA secondary structures involved in many different aspects of RNA metabolism. In this study, we have developed a low-input technique for rG4 detection (G4-LACE-seq) in mouse oocytes and found that rG4s were widely distributed in maternal transcripts, with enrichment in untranslated regions, and they underwent transcriptome-wide removal during meiotic maturation. The rG4-selective small-molecule ligand BYBX stabilized rG4s in the oocyte transcriptome and impaired spindle assembly and meiotic cell cycle progression. The proteomic spectrum results revealed that rG4 accumulation weakened the binding of a large number of RBPs to mRNAs, especially those associated with translational initiation. Ribosomal immunoprecipitation and translational reporter assays further proved that rG4s in the untranslated regions negatively affected the translational efficiency of key maternal mRNAs. Overexpression DEAH/RHA family helicase-36 partially reverses BYBX-induced oocyte developmental defects, suggesting its importance in rG4 regulation. Collectively, this study describes the distribution, dynamic changes, and regulation of rG4s in the mouse maternal transcriptome. Before meiosis resumption, a large number of rG4s in oocytes are necessary to maintain the translatome at a low level, and DHX36-mediated rG4 removal promotes a translational switch and is required for successful maternal-to-zygotic transition.

Tea polyphenols are a class of natural plant compounds with potent antioxidant properties, and their critical role in regulating lipid metabolism has been demonstrated in numerous studies. However, systematic research on the effects of tea polyphenols on lipid metabolism in lion-head geese remains limited. In this study, we examined the impact of tea polyphenols on lipid metabolism in geese through an integrative analysis of transcriptomics and metabolomics. A total of 240 healthy male lion-head geese with similar body weights at 1 day of age were randomly allocated into two treatment groups (6 replicates per group, with 20 geese per replicate). The control group received a basal diet, while the experimental group was supplemented with 1000 mg/kg of tea polyphenols (50.4 % catechin purity) in the basal diet for 18 weeks. The results indicated that serum total antioxidant capacity (T-AOC) and glutathione peroxidase (GSH-Px) activities were significantly increased (P < 0.05), while malondialdehyde (MDA) levels were significantly decreased (P < 0.05) in the tea polyphenol group compared to the control group. Additionally, serum triglycerides (TG), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) activities were significantly lower (P < 0.05) in the tea polyphenol group than in the control group. Hepatic transcriptomic analysis further revealed that tea polyphenols significantly modulated the expression of several genes involved in lipid metabolism, including angiopoietin-like 4 (ANGPTL4), which plays a role in regulating lipid homeostasis, as well as glycerophosphodiester phosphodiesterase domain containing 2 (GDPD2), immunoglobulin heavy chain (IGH), proto-oncogene protein c-fos (FOS), and matrix metallopeptidase 1 (MMP1), etc. Serum metabolomic analysis also demonstrated significant alterations in lipid metabolites induced by tea polyphenols, including the downregulation of fatty acyl metabolites such as L-Palmitoylcarnitine and Hexadecanal. Moreover, the combined analysis revealed a strong positive correlation between ANGPTL4 and the organic compounds of steroidal saponins, such as Glucoconvallasaponin B, and negative correlations with glycerophospholipid metabolites, such as LysoPC (P-16:0).

Calcific aortic stenosis (CAS) is frequently accompanied by systemic comorbidities, but their causal relationships and shared genetic architecture remain poorly defined. We aimed to map the multisystem comorbidity network of CAS and clarify underlying genetic mechanisms. In 467 484 participants from the UK Biobank, observational and polygenic phenome-wide association studies evaluated associations between CAS and 1571 phenotypes, integrating disease-trajectory analyses to visualise temporal patterns. Associations replicated across observational and polygenic analyses were tested using two-sample Mendelian randomisation (MR) based on 22 CAS-related variants from FinnGen. Polygenic risk score (PRS) analyses excluding specific genes assessed their contributions, particularly LPA and plasma lipoprotein(a) (Lp(a)) levels. CAS was associated with higher risks of 42 cardiovascular and non-cardiovascular conditions, most prominently metabolic, endocrine, haematological and respiratory disorders. Temporal analyses showed that circulatory and metabolic diseases typically precede other comorbidities in CAS trajectories. MR findings were consistent with causal effects of CAS on multiple cardiovascular diseases, iron-deficiency anaemia, mental disorders and pleural effusion. When LPA variants were removed from the CAS PRS or plasma Lp(a) concentration was adjusted for, most associations lost significance, indicating a shared LPA/Lp(a)-mediated genetic pathway. CAS is embedded within a broad multisystem comorbidity network, driven largely by genetic variation at LPA and elevated Lp(a). These findings highlight pleiotropic mechanisms linking valvular calcification with systemic disease and support LPA-targeted therapies as a promising avenue for reducing the multisystem burden of CAS.

This study aims to explore how CPS1 influences the progression of lung adenocarcinoma by affecting the ammonia-induced ROS/AMPK/P53/LKB1 signaling pathway. Bioinformatics analysis was conducted to identify differential gene expression in lung adenocarcinoma patients. A549 cells were infected with control (NC) or CPS1 knockdown (CPS1-KD) lentivirus. Cells were treated with or without AMPK agonists, AMPK inhibitors, P53 agonists, or P53 inhibitors, followed by Western blot analysis of CPS1, NOX2, NOX4, p-AMPK, p-P53, and LKB1 protein levels. The content of MDA and SOD was measured, and the expression of AMPK, caspase-3 and P53 in tumor cells was detected through immunofluorescence. Apoptosis-related protein expression and tumor cell apoptosis were assessed using Western blot and flow cytometry. Tumor cell proliferation was evaluated using CCK-8 assays and colony formation experiments. Tumor size was measured in xenograft models using nude mice. Bioinformatics analysis indicated that LKB1 positively regulates AMPK activity. CPS1 knockdown results in increased ammonia levels, with upregulated expression of NOX2, NOX4, p-AMPK, p-P53, and LKB1 in tumor cells. Elevated P53 levels, along with significant increases in Bax, Caspase-8,and Caspase-12 expression, were observed, promoting apoptosis and inhibiting tumor cell proliferation. AMPK and P53 act to inhibit lung adenocarcinoma progression. CPS1 promotes the progression of lung adenocarcinoma by suppressing ammonia-induced activation of the ROS/AMPK/P53/LKB1 signaling pathway.

High-abundance serum proteins, mostly modified by N-glycans, are usually depleted from human sera to achieve in-depth analyses of serum proteome and sub-proteomes. In this study, we show that these high-abundance glycoproteins (HAGPs) can be used as valuable standard glycopeptide resources, as long as the structural features of their glycans have been well defined at the glycosite-specific level. By directly analyzing intact glycopeptides enriched from serum, we identified 1322 unique glycopeptides at 48 N-glycosites from the top 12 HAGPs (19 subclasses). These HAGPs could be further classified into four major groups based on the structural features of their attached N-glycans. Immunoglobins including IGHG1/2/3/4, IGHA1/2 and IGHM were mostly modified by core fucosylated and bisected N-glycans with rarely sialic acids. Alpha-1-acid glycoproteins (ORM1/2) and haptoglobins (HP) were mainly modified by tri-and tetra-antennary (40 %) N-glycans with antenna-fucoses and sialic acids. Complement components C3 and C4A/B were highly modified by oligo-mannose glycans. The other HAGPs including SERPINA1, A2M, TF, FGB/G and APOB mainly contain bi-antennary complex glycans with the common core structure and (sialyl-) LacNAc branch structures. These HAGPs are easily detected by LC-MS analysis and therefore could be used as standard glycopeptides for glycoproteomic methodology studies as well as possible clinical utilities. Show less

Alzheimer's disease (AD) is an irreversible and progressive neurodegenerative disorder. The vicious circle between amyloid-β peptide (Aβ) overgeneration and microglial dysfunction is an important pathological event that promotes AD progression. However, therapeutic strategies toward only Aβ or microglial modulation still have many problems. Herein, inspired by the Aβ transportation, an Aβ-derived peptide (CKLVFFAED) engineered biomimetic nanodelivery system (MK@PC-R NPs) is reported for realizing BBB penetration and reprogram neuron and microglia in AD lesion sites. This hollow mesoporous Prussian blue-based MK@PC-R NPs carrying curcumin and miRNA-124 can down-regulate β secretase expression, thereby inhibiting Aβ production and reducing Aβ-induced neurotoxicity. Meanwhile, MK@PC-R NPs with excellent antioxidant and anti-inflammatory properties could normalize the microglial phenotype and promote Aβ degradation, providing neuroprotection. As expected, after treatment with MK@PC-R NPs, the Aβ burdens, neuron damages, neuroinflammation, and memory deficits of transgenic AD mice (APP/PS1 mice) are significantly attenuated. Overall, this biomimetic nanodelivery system with anti-Aβ and anti-inflammatory properties provides a promising strategy for the multi-target therapy of early AD. Show less

Metabolism alteration is a common complication of rheumatic arthritis (RA). This work investigated the reason behind RA-caused triglyceride (TG) changes. Fresh RA patients' whole blood was transfused into NOD-SCID mice. Metabolism-regulatory tissues were examined after sacrifice. To verify the findings, tissues of the rats with long-lasting adjuvant-induced arthritis (AIA) were analyzed. Some rats were injected with human plasma and GPIHBP1, and their blood TG was monitored. Various cells were stimulated by cytokines or rheumatic subjects' serum. Some pre-adipocytes were cultured by human serum or in the presence of HUVEC cells and GPIHBP1. TG decrease occurred in blood and white adipose tissues (WAT) of the RA blood-transfused NOD-SCID mice and chronic AIA rats. Fatty acids (FA) oxidation in muscles was accelerated a bit, while TG catabolism status in their livers was varied. TNF-α, IL-1β, IL-6 and RA/AIA serum promoted expression of TG utilization-related enzymes and FA uptake transporters in pre-adipocytes, but barely affected LPL. Mild IL-6 stimulus promoted GPIHBP1 release of HUVEC cells. GPIHBP1 was increased in RA serum. This change can decrease blood TG in rats, which was overshadowed by an injection of excessive GPIHBP1. RA serum slightly inhibited LPL secretion in pre-adipocytes. Both HUVEC cells co-culture and GPIHBP1 supplement reduced LPL distribution on pre-adipocytes, and eliminated LPL activity difference between normal and RA serum-treated cells. No TG uptake difference was observed in these circumstances. RA-associated inflammation induces GPIHBP1 secretion of endothelial cells, which facilitates blood TG hydrolysis and uptake to compensate the loss in WAT. Show less
