Osthole is found in Cnidium monnieri (L.) and has anti-inflammatory and anti-oxidative properties. It also inhibits the proliferation of hepatocellular carcinoma cells. This study aimed to evaluate the osthole suppressive nonalcoholic fatty liver disease effects in oleic acid (OA)-induced hepatic steatosis and if it can modulate inflammatory responses and oxidative stress. FL83B cells were pretreated with OA (250 μÎ) for 24 h, and then added different concentrations of osthole (3-100 μM) for 24 h. Subsequently, lipolysis and transcription factors of adipogenesis and phosphorylation of AMP-activated protein kinase proteins were measured. In addition, cells with OA-induced steatosis were H2O2-stimulated, and then incubated with osthole to evaluated if it could suppress its progression to steatohepatitis. Osthole significantly enhanced glycerol release and lipolysis protein expression. Osthole also promoted phosphorylation of AMP-activated protein kinases and increased the activity of triglyceride lipase and hormone- sensitive lipase. Osthole suppressed the nuclear transcription factor kappa-B and the p38 mitogen-activated protein kinase pathway, and decreased the malondialdehyde concentration in FL83B cells with OA-induced steatosis that were treated with H2O2. These results suggest that osthole might suppress nonalcoholic fatty liver disease by decreasing lipid accumulation, and through its anti-oxidative and anti-inflammatory effects via blocked NF-κB and MAPK signaling pathways.
