Abstract
. Metabolomic analysis and RT-qPCR tests indicated that MYR upregulated hepatic bile acid biosynthesis, evidenced by increased total bile acid levels and enhanced expression of key enzymes CYP7A1 and CYP8B1, particularly through the classical biosynthetic pathway. Spearman's correlation analysis revealed strong associations between the regulated bile acids and these aforementioned bacteria. Therefore, our results demonstrated that MYR exerts an anti-atherosclerotic effect by modulating the gut-liver axis.
