The Protective Effects of Imperatorin on Acetaminophen Overdose-Induced Acute Liver Injury.

ABSTRACT: Acetaminophen (APAP) toxicity leads to severe acute liver injury (ALI) by inducing excessive oxidative stress, inflammatory response, and hepatocyte apoptosis. Imperatorin (IMP) is a furanocoumarin from Angelica dahurica, which has antioxidant and anti-inflammatory effects. However, its potential to ameliorate ALI is unknown. In this study, APAP-treated genetic knockout of Farnesoid X receptor (FXR) and Sirtuin 1 (SIRT1) mice were used for research. The results revealed that IMP could improve the severity of liver injury and inhibit the increase of proinflammatory cytokines, oxidative damage, and apoptosis induced by overdose APAP in an FXR-dependent manner. We also found that IMP enhanced the activation and translocation of FXR by increasing the expression of SIRT1 and the phosphorylation
