Fibroblast Growth Factor 15 Deficiency Increases Susceptibility but does not Improves Repair to Acetaminophen-induced Liver Injury in Mice

The leading cause of acute liver failure (ALF) is hepatotoxicity from acetaminophen (APAP) overdose. However, limited options are available to treat this ALF so stimulating liver regeneration maybe a potential treatment. Our previous study has shown that fibroblast growth factor 15 (FGF15) plays a crucial role in liver regeneration, but the roles of FGF15 in liver injury and repair following APAP-overdose are unknown. In this study, treatment of FGF15 knockout (KO) male mice with APAP at 200, 250, or 300mg/kg significantly increased the degree of liver injury compared to wild type (WT) mice.
