Research suggests that lipid levels may be associated with suicide risk. However, the specific relationship between Apolipoprotein B and suicidal ideation remains unclear. The aim of this study was to investigate the association between ApoB levels and suicidal ideation and to further explore the causal relationship using Mendelian randomization. A cross-sectional study of 6520 U.S. adults was conducted using the 2011-2016 National Health and Nutrition Examination Survey (NHANES) dataset. Multiple logistic regression, smoothed curve fitting, stratified analyses, and interaction tests were used to reveal the relationship between ApoB levels and suicidal ideation. MR analyses were conducted using inverse variance weighting (IVW), GSMR, Maximum likelihood method, and cML-MA-BIC MR method. Sensitivity analyses included MR-Egger intercept test, MR-PRESSO global test, and leave-one-out (LOO) analysis. Multivariate logistic regression analysis showed that serum ApoB levels were positively associated with suicidal ideation, and the association remained significant even after multiple covariates (P = 0.0463). Subgroup analyses showed that the risk of suicidal ideation was significantly increased in the highest tertile (T3) of the population compared to the lowest tertile (T1) of ApoB levels (OR = 1.48, 95% CI: 1.04-2.12, P = 0.0312). In addition, the association between ApoB and suicidal ideation was more significant in the smoking subgroup (P interaction = 0.034). However, MR analysis failed to confirm a significant causal effect of ApoB levels on suicidal ideation (P > 0.05), and these results were robust to sensitivity analyses. The present study found a significant positive association between serum ApoB levels and suicidal ideation, especially among smokers. MR analysis failed to provide causal evidence of ApoB on suicidal ideation. More research is needed to clarify the potential role of ApoB in the development of suicidal ideation. Show less

Ischemic stroke is a heterogeneous disease influenced by inflammation, coagulation dysfunction, and metabolic disturbances. However, integrated analysis incorporating these biological domains for patient stratification remain limited. A retrospective study of 132 ischemic stroke patients was conducted. Clinical, coagulation, inflammatory, and metabolic parameters were collected. Principal component analysis (PCA) was applied for dimensionality reduction and visualization. PCA revealed underlying heterogeneity among patients. Validated Data driven clustering identified biologically distinct ischemic stroke subtypes based on inflammation, coagulation, and metabolic profiles. This stratification highlights the heterogeneity of ischemic stroke and may inform future personalized approaches to risk assessment and management. Show less

Enlicitide decanoate, an oral proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitor, was shown to reduce low-density lipoprotein (LDL) cholesterol levels in a phase 2 trial; longer-term data are needed. In this multinational, double-blind, randomized, placebo-controlled trial, we enrolled adults with a history of a major atherosclerotic cardiovascular disease event with an LDL cholesterol level of 55 mg per deciliter or higher and those who were at risk for a first atherosclerotic cardiovascular disease event with an LDL cholesterol level of 70 mg per deciliter or higher. Participants were assigned in a 2:1 ratio to receive enlicitide at a dose of 20 mg or placebo daily for 52 weeks. The primary end point was the mean percent change in LDL cholesterol level from baseline to week 24. Key secondary end points were the mean percent change in LDL cholesterol level at week 52 and the mean percent change in levels of non-high-density lipoprotein (non-HDL) cholesterol and apolipoprotein B and the percent change in lipoprotein(a) level at week 24. Of the 2909 participants in the intention-to-treat population, 1935 received enlicitide and 969 received placebo (5 did not receive enlicitide or placebo). The mean age of the participants was 63 years, and 39.3% were women. The mean (±SD) LDL cholesterol level at baseline was 96.1±38.9 mg per deciliter. The mean percent change in LDL cholesterol levels at week 24 was -57.1% (95% confidence interval [CI], -61.8 to -52.5) with enlicitide and 3.0% (95% CI, 0.9 to 5.1) with placebo, representing an adjusted between-group difference of -55.8 percentage points (95% CI, -60.9 to -50.7; P<0.001). The mean percent change in LDL cholesterol level at week 52, the mean percent changes in non-HDL cholesterol and apolipoprotein B levels at week 24, and the percent change in lipoprotein(a) levels at week 24 were significantly greater with enlicitide than with placebo (P<0.001 for all comparisons). The incidence of adverse events did not appear to differ between the groups. Among participants who had a history of or were at risk for a first atherosclerotic cardiovascular disease event, treatment with the oral PCSK9 inhibitor enlicitide resulted in significantly lower LDL cholesterol levels than placebo at 24 weeks.

Residual cardiovascular risk persists in statin-treated patients with coronary artery disease (CAD), even when low-density lipoprotein cholesterol (LDL-C) targets are met. Excess apolipoprotein B (apoB), defined as measured apoB minus LDL-C-predicted apoB, may capture atherogenic particle burden beyond LDL-C, but its prognostic value for long-term mortality in secondary prevention remains uncertain. We conducted a pooled analysis of two nationwide Chinese cohorts (CIN-II and RED-CARPET) comprising 68,616 statin-treated CAD patients. Excess apoB was calculated using an internal reference population (triglycerides ≤ 1.0 mmol/L). Associations with all-cause and cardiovascular mortality were assessed using multivariable Cox models, with adjustment for clinical covariates including nutritional status. External validation was performed in 13,702 participants from the UK Biobank. Over a median follow-up of 5.2 years, 10,835 deaths occurred (5,090 cardiovascular). Each 1-standard deviation (15.4 mg/dL) increase in excess apoB was associated with a 12% higher risk of all-cause mortality (adjusted hazard ratio [aHR] 1.12, 95% CI 1.06-1.18) and a 24% higher risk of cardiovascular mortality (aHR 1.24, 95% CI 1.15-1.34). Patients in the highest excess apoB quartile (≥ 11.5 mg/dL) had significantly worse survival. Notably, these associations persisted consistently across all achieved LDL-C strata (< 2.0 to > 4.0 mmol/L). These findings were robustly confirmed in the external validation cohort. Excess apoB is an independent predictor of long-term mortality in statin-treated CAD patients, even among those with well-controlled LDL-C. Its incorporation into risk assessment could improve prognostic stratification and guide personalized management in secondary prevention.

Lipoprotein(a)-targeted therapies are emerging approaches for lowering lipoprotein(a) [lp(a)]. We conducted a systematic review and network meta-analysis to evaluate the efficacy and safety of lipoprotein(a)-targeted therapies in patients. We searched PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) up to May 6, 2025, for randomized controlled trials (RCTs) with intervention duration of at least 12 weeks. The primary outcomes were percentage and absolute changes in Lp(a). Secondary outcomes included changes in low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B (apoB), and safety outcomes including adverse events (AEs), serious adverse events (SAEs), and injection-site reactions. A frequentist framework network meta- analysis was performed. Nine studies involving 1,432 participants were included. All six Lp(a)-targeted therapies significantly reduced Lp(a) levels. Compared with placebo, Olpasiran was the most effective therapy for both percentage [mean difference: -92.06, 95% (-109.80; -74.32), Lp(a)-targeted therapies achieved substantial reductions in Lp(a). Olpasiran was the most effective agent in lowering Lp(a) levels. These therapies also improved LDL-C and apoB. The majority of Lp(a)-targeted therapies demonstrate generally favorable safety profiles; However, injection-site reactions, particularly with Zerlasiran, warrant careful consideration. https://www.crd.york.ac.uk/PROSPERO/view/CRD420251069288, PROSPERO CRD420251069288.

Clutch length is a key determinant of reproductive efficiency in geese and strongly positively correlates with egg production. We recorded daily egg production in 280 individually housed Zi geese, calculated clutch-related indices, and selected 12 geese to form long-clutch (LC) and short-clutch (SC) groups for ovarian transcriptomic, proteomic, and metabolomic analyses. The results showed that egg number, large clutch length, large clutch number, average clutch length, and average clutch number were significantly higher in LC than in SC groups (P < 0.0001). Transcriptomic analysis identified 885 differentially expressed genes enriched in oocyte development and ovarian steroidogenesis, with APOB, PLA2G4C, MMP2, MMP9, and NOBOX as key genes; proteomic analysis identified 437 differentially abundant proteins enriched in arachidonic acid metabolism and mitophagy, with CXCL12, RARB, and MAD2L1 as key proteins; and metabolomic analysis identified 35 differentially abundant metabolites enriched in glycolysis/gluconeogenesis, with lactic acid, guanidinoacetic acid, and 3-hydroxybutyrylcarnitine as key metabolites. Integration of multi-omics datasets highlighted a lactate-associated cross-omics signature supported by YWHAZ at the protein level and by the lactate transporter SLC16A3. Collectively, these findings deepen our understanding of the molecular basis underlying clutch-length variation in goose ovaries and highlight candidate genes, proteins, and metabolites for future functional validation.

Apolipoprotein B (apoB) is a well-known risk factor for atherosclerosis. However, studies examining its relation to atrial fibrillation (AF) have produced conflicting results and suggested possible sex-specific differences. This study investigated the sex-specific associations between serum apoB concentrations and incident AF and offer insight into the inconsistencies in previous research. A prospective analysis of 26,803 participants without pre-existing AF was performed using data from the Malmö Diet and Cancer Study. Sex-specific associations between apoB and AF were assessed using multivariable Cox proportional hazards models. To ensure the robustness of the results, several sensitivity analyses, such as restricted cubic spline modeling, competing risks regression, alternative adjustment strategies, subgroup analyses, follow-up time restrictions, and multiple imputation for missing data, were conducted. For median follow-up periods of 21.2 and 24.8 years in men and women, respectively, 2,768 and 2,968 incident cases of AF were recorded, respectively. Among women, unadjusted models showed a strong positive association between apoB and AF, with the highest versus lowest quartile showing a hazard ratio (HR) of 1.65 (95% confidence interval [CI] 1.49–1.84; Results show sex-specific observational links between apoB concentrations and risk of AF. In women, higher apoB levels were linearly inversely associated with AF, whereas in men, the association was borderline non-linear, with inverse effects seen mainly at lower apoB concentrations. These sex differences in AF susceptibility may partly reflect underlying atrial electrophysiological variations and hormonal influences, though whether these factors directly mediate the apoB-AF association remains speculative.

Acute alcohol consumption is known to exert widespread physiological effects, yet the immediate impacts on metabolic biomarkers remain incompletely understood. The present randomized controlled trial was conducted to investigate the acute effects of a single episode of alcohol ingestion on various biomarkers in healthy individuals. A total of 45 male participants were recruited and randomized into an alcohol group (n = 40) and a control group (n = 5) at an 8:1 ratio. Volunteers in the alcohol group ingested 40% Absolut vodka within 15 min. Blood pressure, heart rate, and blood oxygen saturation were measured at 0 h, 1 h, 3 h, 5 h, 12 h, and 24 h. Venous blood samples were drawn at 0 h, 1 h, 5 h, 12 h, and 24 h after alcohol intake. Our results showed that levels of liver function markers, including α-fucosidase (AFU), albumin (ALB), and alkaline phosphatase (ALP), were significantly increased in the alcohol group compared to the control group. The 24-h area under curve (AUC) of AFU, ALB, and ALP were significantly higher in the alcohol group. The liver fibrosis maker collagen type Ⅳ (Ⅳ-C) tended to be higher at 1 h and 12 h in the alcohol group compared to the control group. Lipid levels, including triglycerides (TG), apolipoprotein A1 (APOA1), and the APOA1/APOB, were significantly elevated after alcohol ingestion, particularly at 5 h and 12 h. The 24 h-AUC of TG, APOA1, and APOA1/APOB were higher in the alcohol group than in the control group. Additionally, cardiac function indicators, including heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP), were significantly elevated in the alcohol group. SBP and DBP remained higher 24 h after alcohol ingestion compared to the control group. This study demonstrated that even a single episode of binge drinking could induce significant alterations of biomarkers related to liver function, cardiac function, and lipid profiles. These findings provided valuable insights into the short-term impact of alcohol on health and highlighted the importance of further research to explore the long-term implications of repeated acute alcohol exposure. Given the very small control group, these results should be interpreted as preliminary and confirmed in larger, more balanced randomized trials.

Coronary heart disease (CHD) burden is increasing, and traditional obesity measures inadequately capture fat distribution and associated CHD risk. A body shape index (ABSI) is an emerging anthropometric metric of fat distribution, but evidence linking ABSI to CHD is limited, particularly in the Chinese population. This case-control study in southern China investigated the association of ABSI and related factors with CHD risk, aiming to facilitate early identification of high-risk individuals. We retrospectively studied 996 patients who underwent coronary angiography in a southern Chinese hospital. After strict screening and propensity score matching (PSM), 125 patients with CHD (>50% coronary stenosis) and 125 controls (<50% stenosis) were selected. Key CHD risk predictors were identified using feature-selection techniques (LASSO regression, recursive feature elimination, random forest importance). Univariate and multivariate logistic regression models were constructed for CHD prediction. Model performance was evaluated by receiver operating characteristic (ROC) analysis and compared to individual predictors using the DeLong test. A nomogram was developed for individualized risk estimation. Baseline characteristics were well matched between CHD and control groups after PSM. Across feature-selection methods, the most influential predictors for CHD included ABSI, prealbumin (PA), direct-to-total bilirubin ratio (DB/TB), apolipoprotein B (ApoB), globulin (GLO), apolipoprotein A-I (ApoA-I), and essential hypertension (EH). Each of these factors showed a significant univariate association with CHD ( This study identifies ABSI as a potential predictor of CHD risk among southern Chinese populations. Integrating ABSI with other candidate predictors improves the model's predictive performance. A multifactorial approach may better characterize CHD risk in this population and could inform prevention strategies. Show less

To develop and validate a prediction model for in-hospital cardiogenic shock (CS) after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) based on machine learning (ML) algorithms. A total of 1608 AMI patients admitted to the First Hospital of Lanzhou University during 2023 and 2024 were retrospectively enrolled in this study. The 851 patients from 2023 were randomly divided into a training set ( LASSO regression initially identified 13 candidate features, while the random forest (RF) model demonstrated the best predictive performance in the training set. Following Boruta refinement, seven key features were retained, leading to the construction of an updated RF model. This model achieved an AUROC of 0.906, an accuracy of 0.977, a precision of 0.900, a sensitivity of 0.643, a specificity of 0.996, and a F1 score of 0.750 on the internal validation set. Temporal external validation at the same center showed an AUROC of 0.988, an accuracy of 0.967, a precision of 0.701, a sensitivity of 0.904, a specificity of 0.972, and a F1 score of 0.790. Furthermore, the model demonstrated excellent calibration, with a Brier score of 0.023 and 0.027. The SHAP analysis ranked feature importance as Killip class, D-dimer (DD), creatinine (Crea), alanine aminotransferase (ALT), apolipoprotein B/A (APOB/A), diastolic blood pressure (DBP) and lactate (Lac). We developed and validated a RF model based on seven key variables—Killip class, DD, Crea, ALT, APOB/A, DBP and Lac—that serves as a predictive tool for identifying the risk of in-hospital CS in AMI patients post-PCI. Additionally, we created an online prediction application using Streamlit, which facilitates the implementation of this model into clinical practice. Show less

The objective of this research was to investigate the association between non-traditional lipid parameters and optical coherence tomography (OCT)-characterized high-risk plaques in patients with acute myocardial infarction (AMI). This retrospective study included 249 first-episode AMI patients admitted to the First Affiliated Hospital of Lanzhou University between January 2022 and December 2024. All patients underwent OCT-guided assessment of culprit lesions before revascularization. High-risk plaques were defined by more than two of the following features: lipid arc ≥90 °, fibrous cap thickness <65 μm, or plaque rupture/thrombus. Lesions with fewer than two of these criteria were classified as non-high-risk plaques. Clinical and laboratory data were collected, and a comprehensive lipid profile was calculated, including traditional indicators [e.g., non-HDL cholesterol (non-HDL-C)] and non-traditional ratios [e.g., apolipoprotein B/A1 ratio (ApoB/A1)]. Spearman correlation was used to assess relationships between lipid parameters and high-risk plaques. After excluding collinear variables, logistic regression, restricted cubic spline (RCS), and subgroup analyses were performed. Model discrimination and clinical value were evaluated using receiver operating characteristic (ROC) curves, the DeLong test, integrated discrimination improvement (IDI), net reclassification index (NRI), and decision curve analysis (DCA). Among 249 AMI patients, 137 (55.0%) exhibited OCT-characterized high-risk plaques. These patients were more often male (89.8%) and presented with STEMI (84.7%). They had elevated levels of myoglobin, LDL-C, non-HDL-C, ApoB, ApoB/A1, remnant lipoprotein cholesterol (RLP-C), non-HDL-C/HDL-C ratio (NHHR), and TC/HDL-C (all Both the non-traditional ApoB/A1 ratio and the traditional lipid marker non-HDL-C were independently and linearly associated with OCT-characterized high-risk plaques in AMI. Their combined assessment enhanced the identification of high-risk plaques morphology. Show less

Staphylococcus aureus is a significant pathogen that poses a threat to both human and animal health. Its pathogenicity in humans has been extensively studied, however, the signaling pathways and key genes in Koi Carp responding to S. aureus from human rhinitis remain unclear. In this study, we established an intraperitoneal infection model in koi carp (Cyprinus carpio) using an S. aureus isolate from patients with rhinitis and integrated RNA-seq, qPCR, and ELISA to dissect the host response. Our findings reveal a dual-module immune evasion strategy employed by S. aureus in koi carp. Module I: The pathogen down-regulated the entire complement coagulation cascade (C3, C9, CFH, F7/9/10) and apolipoprotein-mediated opsonins (APOA1, APOB, APOC1/2), thereby crippling innate clearance. Module II: The host mounted a restricted but potent counter-response, characterized by type I IFN signalling (gvin1, MHC-I), NK/T-cell co-stimulation (CD244, SLAMF5), and the selective induction of IL-8 and IL-1β, while IL-6, IL-10, and TNF-α remained unchanged. Functionally, serum superoxide dismutase (SOD), catalase (CAT), and lysozyme (LZM) activities surged, confirming an oxidative burst, whereas splenic CD22R protein decreased, indicating B-cell disinhibition. These results establish a molecular basis for understanding the interaction between human-derived S. aureus and the immune system of aquatic organisms. Show less

To explore the clinical value of D-lactate (D-LA), apolipoprotein B/A1 ratio (APO B/A1) and systemic immune-inflammatory response index (SIRI) in acute pancreatitis (AP) progression and concurrent infectious pancreatic necrosis. This retrospective study included 116 AP patients (Jun 2021 - Dec 2024, Chongqing University Qianjiang Hospital). Patients were assigned to the model group, categorized into bedside indices for severity in acute pancreatitis (BISAP) of mild (n=57), moderate (n=31), and severe (n=28) subgroups. D-LA, APOB/A1, SIRI, and BISAP were compared. Correlations were analyzed via Pearson. Patients were also divided into an infected group (36 cases) and a non-infected group (80 cases) to compare clinical data as well as the above indices. Multivariate logistic regression identified its influencing factors. An external cohort (54 patients) validated the model via ROC and calibration curves. As the severity of AP worsens, D-LA, APO B/A1, and SIRI all increase, and D-LA, APO B/A1, and SIRI were positively correlated with BISAP scores ( D-LA, APO B/A1, SIRI correlate with AP severity and the combined model enables early assessment and personalized measures.

Hypothyroidism, the most prevalent endocrine disorder globally, is associated with increased cardiovascular risk. This study aims to evaluate cardiovascular risk factors-including serum oxidized low-density lipoprotein (ox-LDL), serum homocysteine (Hcy), and lipid profiles-and their correlations with thyroid-stimulating hormone (TSH) levels. Early identification of these risk predictors may reduce the incidence and mortality of cardiovascular disease in hypothyroid patients. This cross-sectional study included 676 participants. Subjects were stratified into four groups: three corresponding to TSH quartiles within the reference range and a fourth comprising subclinical hypothyroidism (SCH) patients with TSH levels above this range. All participants underwent physical examinations and provided fasting blood samples for measurement of TSH, free thyroxine (FT4), free triiodothyronine (FT3), blood glucose, triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB), lipoprotein(a) [Lp(a)], ox-LDL, and Hcy. Across the four subgroups, LDL-C, ApoB, ox-LDL, and Hcy levels exhibited significant increasing trends (all The observed correlations between ox-LDL, Hcy, and dyslipidemia in subclinical hypothyroidism may indicate a proatherogenic state.

In recent years, except for the well-known heart failure with reduced ejection fraction (HFrEF), the incidence of heart failure with preserved ejection fraction (HFpEF) and heart failure with mildly reduced ejection fraction (HFmrEF) among the classification of heart failure (HF) has been increasing. However, due to their complex mechanisms, current research remains insufficient to address clinical needs. Utilizing wild-type (WT), miR-30a-5p knockout (KO), and overexpression (OE) murine models combined with estrogen modulation and ovariectomy (OVX), this study delineates sex-specific regulatory networks in HF pathogenesis. Female KO mice lost the inherent resistance of WT females to HFpEF induction via 24-week HFD/L-NAME, whereas males exhibited comparable HFpEF susceptibility regardless of genotype, developing hallmark phenotypes including diastolic dysfunction (E/E'), myocardial hypertrophy (heart weight/tibia length), cardiac fibrosis, and hepatic steatosis. Particularly, due to the reduced ejection fraction in KO mice, combined with HFD/L-NAME, the HF phenotype was ultimately manifested as impaired diastolic function and slightly reduced ejection fraction (with the characteristics of HFpEF and HFmrEF). Mechanistically, KO-HF females displayed significant estrogen axis disruption (plasma estradiol and the expression of ERα, ERβ, ESRRA, and PELP1 expression). OVX in WT females validated the importance of estrogen for HFpEF resistance. Transcriptomic profiling identified convergent targets across cardiac (ITGAD, ITGAM, FGA, and FGB) and hepatic tissues (APOA1 and APOB), revealing miR-30a-5p's orchestration of extracellular matrix remodeling (via ITGAD/ITGAM mechanotransduction),fibrinogen-mediated microvascular homeostasis, and APOB-driven metabolic dysregulation. Notably, OE intervention failed to mitigate OVX-induced cardiac/hepatic pathology, implicating estrogen-dependent miR-30a-5p functionality. These findings establish miR-30a-5p as a crucial sex-specific regulator of HF (mainly HFpEF), operating through estrogen signaling to balance cardiac compliance and metabolic adaptation. Show less

Metabolic-dysfunction associated steatohepatitis (MASH) arises from sustained triglyceride overload of the intestine-liver axis, yet current therapies rarely coordinate intestinal lipid entry with hepatic triglyceride disposal. Here we identify a phenolic-acid fraction as a dual-compartment metabolic modulator that couples intestinal lipase inhibition to CPT1α-PPARα-dependent hepatic β-oxidation across species. Across species, we investigated the kinetics and metabolic actions of a phenolic fraction (PhAM) using recombinant lipase systems, epithelial transport assays, hepatocyte models, pharmacokinetics, diet-induced metabolic disease paradigms, quantitative histopathology, and a 24-week randomized placebo-controlled clinical trial. PhAM selectively suppresses pancreatic and intestinal lipases non-competitively, lowering V_max with minimal K_m change, resembling some features of orlistat, but via a distinct, non-covalent mechanism. In Caco-2 monolayers and ex vivo loops, it reduces apical-to-basolateral fatty-acid flux, depletes intracellular triglycerides, and limits luminal-to-plasma lipid transfer. PhAM is orally bioavailable, with measurable plasma exposure and prolonged intestinal residence. Under high-fat feeding, it increases fecal fat loss, attenuates post-lipid-load triglyceride excursions, and lowers hepatic triglycerides without altering ApoB secretion. Its triglyceride-lowering effect requires CPT1α-dependent mitochondrial import and PPARα activation, elevates β-hydroxybutyrate, and induces oxidative genes while sparing lipogenesis. In chronic MASH, PhAM reduces steatosis, ballooning, inflammation, and metabolic-dysfunction associated steatotic liver disease (MASLD) Activity Score. A 24-week clinical subgroup, defined by ultrasound and transaminase enrichment, showed dose-responsive improvements in ultrasonographic steatosis and metabolic biomarkers. Collectively, these findings define PhAM as a phenolic-acid-based agent that aligns intestinal lipid restriction with hepatic oxidative unloading, offering a mechanistically coherent framework for potentially addressing steatotic liver disease-associated metabolic features.

The effects of lipid traits on colorectal cancer (CRC) risk and the extent to which obesity may modify these effects remain unclear. To examine the associations between lipid traits and CRC risk using an observational study and Mendelian randomization (MR) analyses, and the role of weight status in the potential associations. In the Guangzhou Biobank Cohort Study (GBCS), lipid profiles were measured during 2003-2008, and CRC events were identified through record linkage with the cancer registry. MR analyses assessed the causal effects of lipid traits on CRC using a genome-wide association study meta-analysis of 185,616 Europeans. Among 28,576 GBCS participants followed until 2020, 599 CRC events occurred. Participants in the highest quartile of apolipoprotein B (apoB) had a higher CRC risk (hazard ratio [HR] 1.43, 95% CI 1.02-2.01). This association remained in those with overweight/obesity (HR 2.21, 95% CI 1.28-3.83). MR analyses supported a detrimental effect of apoB on CRC (odds ratio 1.12 per 1 SD, 95% CI 1.02-1.22). MR analyses also showed positive associations for total cholesterol and the apoB/apolipoprotein A-I ratio, which were not significant in the observational study. Higher apoB levels were associated with an increased CRC risk in both observational and MR analyses, suggesting a potential role of apoB in CRC prevention, especially among participants with overweight/obesity. However, the limitations of single-time lipid measurements and the use of different ancestries across study designs indicate the need for further research to confirm the robustness and generalizability of the findings.

Residual cardiovascular risk persists in type 2 diabetes mellitus (T2DM) despite intensive risk-factor management. Apolipoprotein B (apoB) and excess apoB are potentially promising biomarkers for identifying residual cardiovascular risk. We assessed apoB and excess apoB in T2DM for incremental prediction of atherosclerotic cardiovascular disease (ASCVD) risk. This prospective cohort included 11,918 UK Biobank participants (mean age 59.7 ± 6.6 years; 61% male) with T2DM and no ASCVD at baseline. Excess apoB was defined as the observed minus predicted apoB, where the predicted value was derived using a linear regression model of apoB on low-density lipoprotein cholesterol (LDL-C) fitted in a statin-naïve reference subset with triglycerides ≤ 1.0 mmol/L. The primary endpoint was incident ASCVD. Secondary endpoints included major adverse cardiovascular events (MACE) and all-cause mortality. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable Cox models. Nonlinearity was assessed using restricted cubic splines. Incremental improvements were quantified using the C-index, net reclassification improvement (NRI). During a median 185.3-month follow-up, 2,548 ASCVD and 1,205 MACE events occurred. ApoB was linearly related to ASCVD and MACE, while excess apoB showed J-shaped associations with a nadir near - 7.5 mg/dL for ASCVD. Both apoB and excess apoB showed positive associations with ASCVD across ascending percentile categories. Versus < 50th percentile, HRs (95% CIs) for ASCVD in higher apoB categories (50-<75th, 75-<90th, ≥ 90th) were 1.31 (1.16-1.49), 1.51 (1.25-1.81), and 1.47 (1.10-1.95); corresponding HRs (95% CIs) for excess apoB were 1.50 (1.36-1.66), 1.45 (1.29-1.63), and 1.53 (1.33-1.76), respectively. Similar but weaker risk gradients were observed for MACE. Neither apoB nor excess apoB was associated with all-cause mortality. Excess apoB yielded greater prediction improvement than apoB (ΔC-index: 0.009 vs. 0.002; NRI: 0.270 vs. 0.101) and better stratified risk in statin users and those with LDL-C ≤ 100 mg/dL (P for interaction < 0.05). In T2DM, apoB is independently associated with ASCVD but adds limited discrimination over conventional lipids. Excess apoB yielded improved discrimination and reclassification, and may serve as a complementary ASCVD risk marker, particularly in statin-treated settings. However, its clinical application requires external validation and standardization. Show less

This study aimed to investigate the effects of glycerol monolaurate (GML) on lipid metabolism in young broilers, with focus on the AMPKα1 protein and the cecal microbiota. A total of 144 one-day-old male Arbor Acres broilers were randomly assigned to two groups, with each group consisting of six replicates of twelve birds. The groups were fed diets supplemented with either 0 or 1,200 mg/kg of GML for a period of 14 d. The results showed that GML increased high-density lipoprotein cholesterol levels in the serum (P < 0.05) while reducing total cholesterol, triglyceride, low-density lipoprotein cholesterol, and aspartate aminotransferase levels (P < 0.05). GML also decreased liver lipid droplets and increased the mRNA levels of AMPKα1, CPT1, ApoB, and LXR (P < 0.05). Molecular docking results indicated that GML exhibited good binding affinity with AMPKα1. Root-mean-square deviation values for AMPKα1 and the AMPKα1/GML complex remained stable at 1 to 2 Å within the first 50 ns. The residues in the AMPKα1/GML complex exhibited root-mean-square fluctuation values of less than 2 Å, and the binding energy of the complex was -133.515 kJ/mol. Moreover, GML significantly increased the expression levels of GPR119 and AMPKα1 in the jejunum (P < 0.05). Notably, the genera CHKC1001, Coprobacter, and Ruminococcaceae_UCG₀₀₅ were significantly enriched in the GML group (P < 0.05). PICRUSt2 function prediction revealed that GML-induced alterations in the cecal microbiota primarily involved fatty acid degradation (P < 0.05). In conclusion, dietary supplementation with 1200 mg/kg GML enhanced lipid metabolism in young broilers. Show less

Sepsis is a syndrome caused by the host's inflammatory response to an infection with an unknown mechanism. This study aimed to identify differentially expressed genes (DEGs) potentially involved in the development and recovery of tracheal injury from septic shock. Nine New Zealand white rabbits were randomized to control (CON), septic shock model (SS), and septic shock norepinephrine treatment (SSNE) groups (each group n = 3). The SS and SSNE groups were injected with lipopolysaccharide to induce septic shock. The SSNE group was administered Ringer lactate with norepinephrine to maintain normal blood pressure. All animals underwent cuffed endotracheal intubation for 2 h. The injured tracheal segment was harvested. RNA sequencing was performed to identify the DEGs, followed by bioinformatics analysis, and pathological staining (both HE and Masson) was performed for pathological evaluation. Bioinformatics analysis included principal component analysis (PCA), gene set enrichment analysis (GSEA), and protein-protein interaction (PPI) network construction. Key findings were validated by qRT-PCR and immunohistochemistry. We obtained 124 upregulated and 28 downregulated DEGs in SS vs. CON groups, along with 60 upregulated and 178 downregulated DEGs in SSNE vs. SS groups. The pathological score showed that trachea tissue in the SS group had the highest score. The protein-protein interaction (PPI) prediction identified APOB and CD36 as the hub genes. The molecular experiments further confirmed that at mRNA and protein levels, APOB was significantly upregulated, while CD36 was significantly downregulated. Subsequent qRT-PCR and immunohistochemical analyses confirmed that APOB expression was significantly upregulated while CD36 was downregulated in the septic shock group, a trend partially reversed by norepinephrine treatment. Our study results suggest that APOB and CD36 may be involved in the pathogenesis of tracheal injury recovery in septic shock patients treated with NE. Not applicable. Show less

Apolipoprotein B (apoB) is essential for lipoprotein assembly and secretion and plays a central role in the development of cardiovascular disease and metabolic dysfunction-associated steatotic liver disease. Although apoB protein degradation during very-low-density lipoprotein maturation has been extensively studied, the regulation of A forward genetic screen in randomly mutagenized mice identified HELZ2 (helicase with zinc finger 2) as a critical regulator of lipid metabolism. The metabolic effects of HELZ2 mutations or deficiency were evaluated in mice maintained on a chow diet or a high-fat diet. We also used a doxycycline-inducible, liver-specific HELZ2 overexpression model to test the sufficiency of hepatocyte We discovered a unique gain-of-function mutation in HELZ2 (L1833P, called HELZ2 is a key regulator of Show less

The triglyceride-glucose (TyG) index, an insulin resistance marker linked to the progression of metabolic dysfunction-associated steatotic liver disease (MASLD), underscores the redox imbalance-mediated crosstalk between MASLD and cardiovascular-liver-metabolic health (CLMH), although its causal mechanisms and molecular drivers remain unresolved. We employed a multi-omics framework to integrate Mendelian randomization (MR) and transcriptome-wide association studies (TWAS). MR leveraged 192 genome-wide significant single-nucleotide polymorphisms for TyG from the UK Biobank, employing inverse-variance weighted (IVW) and generalized summary-data MR (GSMR). Transcriptomic integration utilized four approaches: Multi-marker Analysis of GenoMic Annotation for gene-set enrichment; Joint-Tissue Imputation PrediXcan (JTI-PrediXcan) for tissue-specific expression; Sparse Multi-Tissue Imputation Xcan (SMulTiXcan) for cross-tissue meta-analysis; and Fine-mapping of Causal Gene Sets (FOCUS) for Bayesian fine-mapping. Comorbid genes were validated using Functional Summary-based Imputation (FUSION) and prioritized based on the Polygenic Priority Score (PoPS). Single-cell spatial transcriptomics (sc-ST) in embryonic mice (E16.5) mapped tissue-specific expression via genetically informed spatial mapping (gsMap). The MR analysis demonstrated a causal effect of TyG on MASLD risk [IVW: odds ratio (OR) = 1.58, 95% CI = 1.04-2.38, P = 0.030; GSMR: OR = 1.43, 95% CI = 1.27-1.61, P = 5.20 × 10 -9 ]. TWAS identified 12 comorbid genes (C2orf16/SPATA31H1, FNDC4, GCKR, GMIP, HAPLN4, LPAR2, MAU2, MEF2B, NDUFA13, NRBP1, TM6SF2, and ZNF513). Independent validation using the FUSION framework confirmed nine TyG-MASLD comorbid genes with genome-wide significant false discovery rate-adjusted associations. Notably, TM6SF2 (TyG-PoPS = 7.2491) and GCKR (TyG-PoPS = 6.7102) showed strong positive associations in TyG, whereas NDUFA13 exhibited negative scores in MASLD (PoPS = -0.5028). Spatial mapping revealed conserved enrichment of APOA1, APOB, and APOC4 (sc-ST, P < 0.001) in murine liver and vascular tissues. Organ-specific analysis showed significant MASLD signals including the liver (sc-ST, P = 6.43 × 10 -5 ), adrenal gland (Cauchy P = 0.0064), and connective tissue (sc-ST, P = 3.29 × 10 -5 ). This study establishes TyG as a causal MASLD driver mediated by redox-sensitive hubs and evolutionarily conserved apolipoproteins, linking hepatic lipid peroxidation to systemic metabolic dysregulation. Targeting these pathways may mitigate dual hepatic-cardiovascular risks, advancing precision therapies for CLMH. Show less

Dysregulation of low-density lipoprotein (LDL) cholesterol is strongly correlated with the risk of metabolic dysfunction-associated steatotic liver disease. Endogenous molecules targeting LDL clearance play crucial roles in the progression of liver steatosis. Human cathelicidin LL-37 can form complexes with lipoproteins, but whether these complexes regulate lipoprotein-driven cholesterol metabolism is not clear. Here, we find that cathelicidin LL-37 binds to LDL via apolipoprotein (Apo)B-100 domains, enhancing the solubility of ApoB-100 and inhibiting the modifications and aggregation of LDL. LL-37-LDL interaction promotes LDL uptake through LDL receptor (LDLR) both in hepatocytes and macrophages. This interaction also promotes LDL cholesterol clearance by facilitating cholesterol excretion and cholesterol efflux. In Apoe Show less

Patients on dialysis often suffer from carnitine deficiency due to reduced intake, reduced synthesis in the kidneys, and clearing through dialysis. Carnitine deficiency may lead to anemia, cardiomyopathy, hypotension, and so on. Several studies have shown that supplementing with L-carnitine can diminish the above symptoms in adult dialysis patients, but whether children can benefit from L-carnitine remains unclear. This study was performed to investigate the effect of L-carnitine in children with kidney failure undergoing dialysis. PubMed, Embase, The Cochrane Library, China National Knowledge Infrastructure (CNKI), WanFang Data, and VIP database were electronically searched from database inception to December 2023. STUDY ELIGIBILITY CRITERIA: We included randomized controlled trials (RCTs), cohort studies, case-control studies, cross-section studies, and case series studies that evaluated the impact of L-carnitine on children. Patients aged less than 18 years with kidney failure undergoing dialysis. STUDY APPRAISAL AND SYNTHESIS METHODS: We assessed the quality of studies using the RoB2 tool recommended by the Cochrane Handbook, the Newcastle-Ottawa Quality Assessment Scale (NOS), the checklist recommended by Agency for Healthcare Research and Quality (AHRQ), and the quality evaluation tool recommended by the National Institutes of Health (NIH). We conducted only descriptive analyses and did not perform meta-analysis due to significant differences in study types and limited data. A total of 194 patients were included in 9 studies, of which 3 were RCT studies; 2 were cohort studies, and 4 were case series studies. Due to limited data, we only conducted descriptive analysis rather than meta-analysis. For children undergoing hemodialysis, cohort study of high-quality showed that L-carnitine significantly improved hemoglobin (Hb) and reduced the required erythropoiesis-stimulating agent (ESA) dose; RCT study of moderate-quality indicated that L-carnitine did not influence serum lipid profiles except for reducing apolipoprotein B (ApoB). Cohort study of moderate-quality showed that L-carnitine improved cardiac function; RCT study of moderate-quality indicated that L-carnitine did not influence albumin, C-reactive protein (CRP), interleukin-6 (IL-6), and quality of life. For children undergoing peritoneal dialysis, only serum lipid profiles were analyzed. RCT and case series studies of moderate-quality indicated that L-carnitine did not influence serum lipid profiles except for reducing ApoB. The number of studies enrolled was limited, and their quality was not high. Our study found that children with kidney failure requiring dialysis could partially benefit from L-carnitine, including increased Hb, decreased ESA requirement, reduced ApoB, and improved cardiac function. Further RCTs of high quality are still needed to clarify this issue. This study provided more comprehensive and credible evidence for clinical use of L-carnitine in children.

Doxorubicin (Dox) is a classic anthracycline chemotherapy drug with cause cumulative and dose-dependent cardiotoxicity. This study aimed to investigate the potential role and molecular mechanism of phenylacetylglutamine (PAGln), a novel gut microbiota metabolite, in Dox-induced cardiotoxicity (DIC). DIC models were established in vivo and in vitro, and a series of experiments were performed to verify the cardioprotective effect of PAGln. RNA sequencing (RNA-seq) was employed to explore the mechanism of PAGln in DIC. Subsequently, the differentially expressed genes (DEGs) were subjected to comprehensive analysis using diverse public databases, and RT-PCR was used to confirm the expression levels of the candidate genes. Finally, molecular docking techniques were used for validation. PAGln effectively prevented both in vivo and in vitro Dox-induced myocardial injury and cell apoptosis. RNA-seq results showed that 40 genes were up-regulated and 54 down-regulated in the Dox group compared to the Con group, displaying opposite changes in the Dox + PAGln group. Enrichment analysis highlighted several mechanisms by which PAGln alleviated Dox-induced cardiotoxicity, including the lipid metabolic process, calcium-mediated signaling, positive regulation of store-operated calcium channel activity, and hypertrophic cardiomyopathy. In vitro and in vivo experiments confirmed that PAGln treatment could reverse the changes in the expression levels of Klb, Ece2, Nmnat2, Casq1, Pak1, and Apob in Dox. Molecular docking results showed that these genes had good binding activity with PAGln. PAGln shows potential in alleviating Dox-induced cardiotoxicity, with Ece2 identified as key regulatory molecules related to endothelial dysfunction. Show less

Primary renal small cell carcinoma (PRSCC) is a rare, poorly differentiated neuroendocrine carcinoma, and its clinicopathological features and the gene mutation spectrum associated with its pathogenesis remain to be elucidated. The present study aimed to characterize the genetic mutation spectrum associated with the pathogenesis of PRSCC, identify novel driver and predisposing genes for the disease, reveal its histopathological features associated with genetic mutations and systematically summarize the clinicopathologic characteristics and prognostic factors of PRSCC patients to provide a theoretical basis for molecularly targeted therapy and prognostic assessment of PRSCC. Whole-exome sequencing (WES) was performed on PRSCC samples to characterize the spectrum of genetic mutations and the results were validated using Sanger sequencing. Immunohistochemistry (IHC) was performed to reveal the histopathological features associated with these mutations. Furthermore, based on the published literature, a population-based study was conducted by searching PubMed and EMBASE databases to systematically summarize the clinicopathologic characteristics and prognostic factors of patients with PRSCC. WES identified 113 somatic single-nucleotide variants, 26 somatic insertions and deletions and mutations in 8 predisposing genes (DST, OR10H3, PTK2B, APOBR, ZNF606, CCN4, ADCK1, and MYH2) and 10 driver genes (KRTAP10-9, HYDIN, ZNF665, KRTAP10-2, GPAM, MUC12, KRT9, CCDC168, DUSP27 and MDC1). Sanger sequencing of germline DNA identified a germline A/G variant in the HYDIN sequence, first reported in PRSCC. Furthermore, IHC analysis indicated that PRSCC was positive for CD56, Syn, insulinoma associated protein 1, CgA and neuron specific enolase. In the population-based study, the majority of patients with PRSCC were elderly (57.92±15.75 years), with a pathological tumor (T) 3/4 stage (68.3%) and presented with lymph node involvement (51.7%) and distant metastasis (51.7%). T stage was an independent prognostic factor for overall survival in patients with PRSCC (P=0.004). Driver mutations in the HYDIN gene may be a key factor in the pathogenesis of PRSCC. HYDIN may serve as a prognostic marker and a target for immunotherapy in the management of PRSCC. However, due to the extreme rarity of PRSCC, the WES analysis in the present study was based solely on individual cases. To ensure the reliability and generalizability of genetic alterations detected by WES, additional PRSCC samples, along with cell and animal experiments, are warranted to confirm the role of these genetic variants (particularly HYDIN) in PRSCC pathogenesis. The functional role of HYDIN mutations in PRSCC pathogenesis requires further validation in future research. Show less

Ischemic heart failure (IHF) is one of the leading causes of death in the world. Plasma apolipoprotein C3 (ApoC3) levels are significantly elevated in patients with heart failure and positively associated with the incidence of ischemic heart disease (IHD). However, the causal association between ApoC3 and IHD development is unclear. ApoC3 expression changes were assessed in plasma from IHF patients/healthy donors and cardiac tissue from rodent models. 10-week-old male human ApoC3 transgenic (ApoC3 Overexpression of human ApoC3 in ApoC3 ApoC3 overexpression could activate cardiac TLR2/NF-κB to trigger the inflammation, oxidation, and apoptosis pathways, finally aggravating IHF in mice. Inactivation of ApoC3 could significantly alleviate IHF in hamsters. Show less

Schizophrenia is frequently comorbid with dyslipidemia and hyperglycemia. However, whether metabolic-modifying agents aggravate schizophrenia progression remains unclear. We perform a drug-target genetic association study in two independent Han Chinese schizophrenia cohorts (N = 2,111/292 for discovery/validation). Leveraging metabolic genome-wide association studies, we generate genetic risk scores (GRSs) for lipid-modifying and hypoglycemic targets. Those with higher APOC3 (inhibited by volanesorsen/olezarsen) GRS exhibit attenuated triglycerides and improvement in negative symptoms assessed by Positive and Negative Syndrome Scale (PANSS) (β = 1.23, 95% confidence interval [CI]: 0.30-2.16). Higher GCK (activated by dorzagliatin) GRS is associated with decreased glucose and less improvement across PANSS total (β = -1.70, 95% CI: -2.91-0.50), positive, negative, general subscales. Causal associations of GCK are replicated in independent validation. The effects of APOC3 and GCK on negative symptom recovery are robust in hyperlipidemic/diabetic subgroups. Genetically proxied proteomics analysis provides further functional validation for the identified target-outcome associations. Our findings suggest volanesorsen/olezarsen as potential adjunctive candidates; dorzagliatin warrants prudence in schizophrenia with metabolic disturbance. Show less
