Pleurotus citrinopileatus (golden oyster mushroom) is a widely used edible mushroom. We investigated the inhibitory effect of P. citrinopileatus aqueous extract against alcoholic steatohepatitis and its underlying mechanism. Acute and chronic ethanol-feeding murine models were established by intragastrically administering ethanol or feeding an ethanol-containing Lieber-DeCarli liquid diet to male C57BL/6 mice. In both models, P. citrinopileatus decreased serum alanine aminotransferase (ALT), aspartate transaminase (AST), triglyceride (TG), and hepatic TG levels. Hematoxylin and eosin (HE) and Oil Red O staining confirmed that P. citrinopileatus ameliorated both acute and chronic alcoholic hepatosteatosis, characterized by regulation of lipid-metabolism-related proteins, including sirtuin 1 (SIRT1), AMP-activated kinase (AMPK), and sterol regulatory element-binding protein (SREBP1). P. citrinopileatus reversed inflammatory response via modulating purinergic receptor P2X ligand-gated ion channel 7 (P2X7R)-NOD-like receptor pyrin domain 3 (NLRP3) inflammasome. P. citrinopileatus restored the expressions of those proteins to a normal level. In addition, HepG2 cells were incubated with P. citrinopileatus prior to ethanol stimulation. P. citrinopileatus reduced ethanol exposure-induced lipid deposition. Concomitantly, P. citrinopileatus increased AMPK and SIRT1 expressions, which were reduced by ethanol treatment. P. citrinopileatus ameliorated alcoholic hepatic steatosis and accompanied inflammatory response via regulating SIRT1-AMPK and P2X7R-NLRP3 inflammasome activation, highlighting a promising strategy and utility of P. citrinopileatus for alcoholic steatohepatitis as dietary health supplements.
