Results indicated that administration of PMP relieved the leakage of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The level of serum ALT was reduced in groups of P-H (800 mg PMP/kg BW) and P-L (400 mg PMP/kg BW) by 44.6% and 31.8%, respectively. RT-PCR and Western blot analyses showed that NF-E2-related factor 2 (Nrf2), PPARα, PPARγ gene and protein were up-regulated after injection D-GalN/LPS. In contrast, PMP pretreatment noticeably prevented D-GalN/LPS-induced hepatocyte apoptosis and steatosis. It suggested that PMP attenuated D-GalN/LPS-induced AHF in mice, which was likely attributed to the co-activation of Nrf2, PPARα, PPARγ and alleviating the oxidative stress reaction, reducing the body inflammatory response and regulating the lipid metabolism.Graphical abstract
