CYP27A1 and Insulin resistance: In turn, insulin resistance notably increases cholesterol secretion by upregulating mRNA levels of cholesterol exporters ABCG5/G8 in hepatocytes and reducing enzymes relating to bile acids synthesis like CYP7A1, CYP7B1, sterol 12 α-hydroxylase (CYP8b1) and sterol 27-hydroxylase (CYP27A1), which results in cholestasis [35–37].
