Leveraging data from the Global Lipids Genetics Consortium (2021) and the UK Biobank, we identified instrumental variables for ASGR1 and validated these genetic instruments using coronary heart disease (CHD) patients as positive controls. We employed Instrumental variable weighted (IVW) and Summary-data-based Mendelian Randomization (SMR) methods to assess the association of ASGR1 with HF and its associated risk factors, comparing efficacy with PCSK9 and LDLR. Mediation analysis of inflammatory biomarkers was conducted using a two-step Mendelian randomization approach, with sensitivity analyses performed using conventional MR methods. IVW analysis demonstrates a significant positive correlation between ASGR1 expression and HF, myocardial infarction, non-ischemic cardiomyopathy, and calcific aortic valvular stenosis. Patients with HF comorbid with CHD showed an increased likelihood of benefit. ASGR1 exhibited a stronger effect on HF compared to PCSK9. Similar conclusions were drawn from SMR analysis. Additionally, LDLR shows no causal relationship with HF but appears negatively correlated with non-ischemic cardiomyopathy. Among the 91 inflammatory proteins studied, Leukemia inhibitory factor receptor (LIF-R) and Urokinase-type plasminogen activator (uPA) were found to mediate the effects of ASGR1 on HF. Sensitivity analyses indicate no evidence of pleiotropy in reported results. This study supports a causal association between ASGR1 inhibitors and HF, providing genetic evidence for the anti-inflammatory role of ASGR1 inhibitors in reducing HF risk.

Rats were provided with AIN-76 basal diet, basal diet +0.5% PS, or basal diet +0.5% OPS. We found that the level of cholesterol and triacylglycerols in the liver was significantly lower in OPS-fed rats than in basal diet-fed rats.

Additionally, the proportion of arachidonic acid (20:4) in the liver was significantly higher in the OPS-fed group compared with the control group. The mRNA expression levels of Δ6 and Δ5 desaturases were significantly higher in OPS-fed rats than in basal diet-fed rats, but remained unchanged in PS-fed rats. Moreover, the protein level of Δ6 desaturase was significantly higher in both PS- and OPS-fed rats compared with basal diet-fed rats, while the protein level of Δ5 desaturase tended to be higher only in OPS-fed rats than in basal diet-fed rats. Thus, exogenous OPS, but not PS, altered fatty acid composition through the upregulation of mRNA and protein levels of fatty acid desaturation enzymes in the liver.

The current study aimed to investigate the relationship between plasma elaidic acid, a major TFA, and sleep complaints. The participants from the US National Health and Nutrition Examination Survey (NHANES) (2009-2010) were included. The plasma concentration of elaidic acid (18:1n-9t) was determined using the gas chromatography/mass spectrometry (GC/MS) method. The sleep outcome was defined based on the following questionnaire: \"Ever told the doctor had trouble sleeping?\" and \"Ever told by a doctor have a sleep disorder?\". Participants were classified as having sleep complaints if they ever told a doctor or been told by a doctor about trouble sleeping. The association between plasma elaidic acid and sleep complaints was investigated by multivariable logistic regressions, restricted cubic spline (RCS), and subgroup analysis. A total of 2068 participants were included, 561 of whom suffered from sleep complaints. The restricted cubic spline (RCS) regression analysis revealed a nonlinear (inverted L-shaped) relationship between plasma elaidic acid level and sleep complaints (p = 0.044), with an inflection point of 9.598 μmol/L.

A meta-regression was conducted to evaluate the relationship between dietary 18-carbon n-3 FA content and the deposition of EPA, docosapentaenoic acid (DPA), and DHA in broiler breast and liver tissue. Bivariate regression of total diet 18-carbon n-3 and tissue FA profile was modeled with the random effect of experiment and the partial R<sup>2</sup> was calculated. Increasing 18C n-3 FA in the diet quadratically increased the log<sub>10</sub> concentration of all n-3 FA in breast tissue. The strongest relationship was found for breast alpha-linolenic (partial R<sup>2</sup> = 0.55), followed by EPA, DPA, and DHA (partial R<sup>2</sup> = 0.20, 0.14, and 0.05). Liver enrichment of EPA, DPA, and DHA (all partial R<sup>2</sup> > 0.43) and EPA + DHA (partial R<sup>2</sup> = 0.55) was quadratically related to dietary 18C n-3 FA, while liver EPA + DPA + DHA (partial R<sup>2</sup> = 0.43) was linearly related to dietary 18C n-3 FA. In both breast and liver, the plateau in tissue enrichment was more apparent for DHA than EPA, with DPA being intermediate. A linear plateau model fit the data with a break point for enriching EPA and DHA in breast muscle at 22.4 and 17.9 g/kg of 18C n-3 FA in the diet, respectively. Enrichment of long-chain n-3 FA in broiler chickens was saturable, with little justification for feeding beyond approximately 20 g/kg 18C n-3 FA.</p>","PeriodicalId":18086,"journal":{"name":"Lipids","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143625012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
