FABP4 and cholestasis: In the present study, A‐FABP knockout (A‐FABP KO) mice and their wild‐type (WT) littermates were subjected to cholestasis‐ or hepatotoxin‐induced liver fibrosis by surgical ligation of the common bile duct (BDL) or chronic administration of carbon tetrachloride (CCl4)[14] to determine the exact role and the molecular mechanism that A‐FABP involved in hepatic fibrogenesis.
