摘要：

The recent discovery that the impairment of autophagic flux in non-alcoholic fatty liver disease (NAFLD) might be a strong determining factor in steatosis suggests the potential of therapeutic control of autophagic flux with natural agents in restoring NAFLD. We investigated the potential of Eucommia ulmoides leaf extract (EUL) to control dyslipidemia in NAFLD. EUL supplementation (200 mg/kg) promoted recovery from high fat diet (HFD)-induced lipid dysmetabolism. This hepatoprotective efficacy was accompanied by suppression of endoplasmic reticulum (ER) stress, enhancing lysosomal functions, and thereby increasing autophagic flux. We found a strong indication that inhibition of the mTOR-ER stress pathway was related to the enhanced autophagic flux. However, the direct antioxidative effect of EUL on cytoprotection cannot be ruled out as a significant contributing factor in NAFLD. Our findings will aid in further elucidating the mechanism of the anti-steatosis activity of EUL and highlight the therapeutic potential of EUL in the treatment of NAFLD.
