This study was designed to investigate the effect on lipoapoptosis of Alisma orientale extract against free fatty acid-induced cellular injury.

Methods :
HepG2 cells were used in an vitro model. HepG2 cells were treated with free fatty acids to generate a cellular model of nonalcoholic fatty liver disease (NAFLD). Using this cellular model, the anti-apoptotic effect and reducing steatosis of Alisma orientale extract against free fatty acid-induced cellular injury was evaluated by measuring steatosis and apoptosis.

Alisma orientale extract significantly attenuated free fatty acid-induced intracellular steatosis. Alisma orientale extract inhibited free fatty acid-mediated activation of pJNK, PUMA, BAX, caspase-3, and –9, and apoptotic kinases that are correlated with NAFLD. Alisma orientale extract also promoted Bcl-2, a anti-apoptotic protein.

From the above, the Alisma orientale extract decreased the hepatocyte steatosis and showed the hepatocelluar protective effect by the regulation of apoptosis-related protein. It proposes the possibility of Alisma orientale extract to the treatment of nonalcoholic fatty liver disease in clinics.
Key words: nonalcoholic fatty liver disease (NAFLD), Alisma orientale, lipoapoptosis, HepG2 cell, free fatty acids (FFAs)
