Up-regulation of CYP3A4 expression in cholestasis. The induction of CYP3A4 expression by bile acids is mediated by FXR (30,60) and PXR (52,60,61). WebBile acids are physiological detergents that generate bile flow and facilitate intestinal absorption and transport of lipids, nutrients, and vitamins. Bile acids also are signaling molecules and inflammatory agents that rapidly activate nuclear receptors and cell signaling pathways that regulate lipid, glucose, and energy metabolism.
