In the present study, we prepared six different wild-type mammalian ALOX-isoforms and a selected enzyme mutant, incubated the recombinant proteins in vitro with free arachidonic acid, arachidonoyl-carnitine, and arachidonoyl-coenzyme A, and quantified the amounts of primary oxygenation products. We found that for most ALOX-isoforms, arachidonoyl-carnitine was oxygenated at a similar rate as free arachidonic acid and that the chemical structures of the primary oxygenation products were identical. In contrast, arachidonoyl-coenzyme A was oxygenated with a 3-5-fold lower rate, but here again highly specific patterns of primary oxygenation products were formed. In silico docking studies and molecular dynamics simulations suggested that free arachidonic acid and arachidonoyl-carnitine are similarly aligned at the active site of rabbit ALOX15, but the binding of arachidonoyl-coenzyme A was sterically hindered because of the bulkiness of the CoA moiety.

Low levels of high-density lipoprotein (HDL) cholesterol are associated with increased risk of death from sepsis, and increasing levels of HDL by inhibition of cholesteryl ester transfer protein (CETP) has been shown to decrease mortality in mouse models of sepsis. The objective of this study was to investigate the cellular mechanisms by which CETP inhibition and HDL lead to improved survival during sepsis. We found that HDL inhibits lipopolysaccharide (LPS)-induced activation of IL-1β in a mouse model of sepsis. The activation of IL-1β was dependent on the activity of scavenger receptor class B type 1 (SR-B1), and knockdown of SR-B1 significantly attenuated LPS-induced production of IL-1β in macrophages. Additionally, we found that LPS-induced SR-B1 internalization occurs through the endosome-lysosome pathway, which is also likely responsible for LPS degradation in the macrophages. Furthermore, we revealed that raising HDL by CETP inhibition markedly enhanced HDL-mediated anti-inflammatory effects in response to LPS stimulation, and these effects were not due to CETP itself but rather were HDL-dependent. Finally, we show that pharmacological inhibition of CETP significantly improved endotoxemia-induced mortality by inhibiting IL-1β production in the liver and circulation after LPS injection. Pathologically, CETP inhibition attenuated LPS-induced diffuse alveolar damage and hepatocyte necrosis, which may contribute to the improved mortality in mice treated with the CETP inhibitor anacetrapib.

Daclatasvir enhances MARCH6-mediated ubiquitination of PLIN2, leading to its degradation, which reduces lipid accumulation, inflammation, and fibrosis-key features of MASLD and MASH. Preclinical models demonstrate its ability to improve lipid metabolism, reduce inflammation, and alleviate liver fibrosis. Despite promising findings, challenges remain. Clinical trials are needed to validate its efficacy and safety in humans, as animal models cannot fully replicate the multifactorial nature of MASLD. Long-term safety and potential off-target effects also require evaluation, especially since PLIN2 may protect against other liver conditions. The study highlights the need for broader screening of FDA-approved drugs and exploration of alternative pathways for PLIN2 regulation.

Using metabolic cages to assess energy intake, we found that the fuel utilization rhythms of DRF mice were disrupted compared to ad libitum-fed mice.

These findings provide new insights into the potential mechanisms linking feeding patterns to lean MAFLD. Additionally, CD36 emerges as a potential therapeutic target for high-fat-induced lean MAFLD.

To identify the presence of MASH, logistic regression was performed on each candidate either in a single or combination with various clinical parameters. Serum levels of desmosterol and phosphatidylcholine are increased in patients with MASH compared to those with MASL. After exclusion of patients using lipid lowering drugs, an increase was also found in serum levels of cholesterol, cholesterol ester, lysophosphatidylcholine, lysophosphatidylethanolamine, phosphatidylethanolamine, and several individual lipid species. The ROC curve of each lipid candidate show the potential use of desmosterol, phosphatidylcholine, and a panel of lipid species in combination with alanine aminotransferase as potential diagnostic markers, characterized by a respective AUROC of 0.79 (95% CI 0.66-0.92), 0.80 (95% CI 0.64-0.97), and 0.91 (95% CI 0.82-1.00). Serum sterol and lipidome markers are characterized by strong AUROC results to distinguish with high accuracy MASH from MASL, potentially paving the way for future MASH biomarker development.</p>","PeriodicalId":16209,"journal":{"name":"Journal of Lipid Research","volume":" ","pages":"100845"},"PeriodicalIF":4.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12284782/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144368983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
