2-Acetamidophenol (2-AAP) Suppresses the Progression of Atherosclerosis by Alleviating Hyperlipidemia and Attenuating the Ferroptosis Pathway.
Hyperlipidemia and consequent endothelial inflammation, along with foam cell generation, promote the progression of atherosclerosis (AS). Here, we aimed to investigate the effects of 2-acetamidophenol (2-AAP), which was selected by zebrafish phenotypic screening, in alleviating AS by relieving hyperlipidemia and inhibiting foam cell formation, as well as the underlying mechanisms. In a zebrafish hyperlipidemia model, 2-AAP increased lipid-lowering efficacy; alleviated TC, TG, LDL-C, and MDA levels; elevated HDL-C and T-SOD levels; significantly improved intravascular macrophage aggregation; and improved blood flow. In an ox-LDL-induced RAW264.7 model, 2-AAP inhibited lipid phagocytosis in RAW264.7 cells; reduced the intracellular TC, TG, FC, and CE contents; and decreased the CE/TC ratio, thus slowing foam cell generation. In addition, 2-AAP alleviated intracellular ROS and ferrous ion accumulation in RAW264.7 cells, reduced the MDA content, and increased GPX4 viability. Furthermore, transcriptome analyses and gene expression validation showed 2-AAP treatment upregulates genes related to GSH synthesis and transport, such as gclc, gclm, gss, and gpx4a, and enhanced the expression levels of genes involved in the storage and transportation of iron ions, such as fpn1, fth, and g6pd, indicating that 2-AAP dramatically regulated the ferroptosis and glutathione metabolic pathways. Overall, our study demonstrated that 2-AAP demonstrated potential in AS by alleviating hyperlipidemia and attenuating the ferroptosis pathway and provided evidence supporting the future application of 2-AAP in AS treatment.
期刊介绍:
Marine Drugs (ISSN 1660-3397) publishes reviews, regular research papers and short notes on the research, development and production of drugs from the sea. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible, particularly synthetic procedures and characterization information for bioactive compounds. There is no restriction on the length of the experimental section.
