Hepatic FXR signaling—BA autoregulation. Hepatic FXR signaling pertaining to BA autoregulation. Hepatic FXR agonism increases BA/cholesterol efflux, primary BA conjugation, and represses BA synthesis. Dashed mechanism arrows represent the Ras-Raf-MEK signaling cascade, while dashed arrows through a protein represent the direction of substrate flux. Proteins with a yellow outline represent kinases and phosphatases, while yellow arrows represent phosphorylation/dephosphorylation. Yellow P’s represent phosphate groups. Italicized text refers to genes while normal text refers to proteins. Question marks represent unknown mechanisms. This figure was created with BioRender.com
