We investigated the effects of chrysin (CHR) on nonalcoholic fatty liver disease (NAFLD) in mice. The NAFLD mouse model was established using a diet deficient in methionine and choline (MCD). CHR was shown to attenuate MCD-induced hepatic fat accumulation, increase very low-density lipoprotein (VLDL) secretion, and decrease hepatic oxidative stress in NAFLD mice. Inhibition of oxidative stress or direct suppression of protein kinase C (PKC) by CHR significantly reduced PKC activity in the liver, leading to a decrease in inhibitory phosphorylation of hepatocyte nuclear factor 4? (HNF4?). The resulting activation of HNF4? led to induced transcription of apolipoprotein B and VLDL secretion. Together, these results show that CHR effectively ameliorates MCD-induced fatty liver in NAFLD mice by targeting the hepatic oxidative stress/PKC/HNF4? signaling pathway.
