NR1H4 and Hepatic fibrosis: FXR agonists: FXR is found mainly in the liver and intestine, a major intercellular BA receptor activated during the fed state to regulate metabolism and inflammation.185,194,195 The interaction of BAs and intracellular FXR not only inversely regulates BA synthesis, but inhibits hepatic adipogenesis and steatosis, reduces hepatic gluconeogenesis, and increases peripheral insulin sensitivity through transcription of GLUT4.185,196–198 Deficiency of FXR leads to increased BA synthesis, which further contributes to liver fibrosis and inflammation and even to HCC.199–201
