Elaeagnus mollis Oil Attenuates Non-alcoholic Fatty Disease in High-fat Diet Induced Obese Mice via Modifying the Expression of Lipid Metabolism-related Genes

摘要

Elaeagnus mollis oil (EMO), which is a type of plant oil, was extracted from the nuts of Elaeagnus mollis Diels that is known as a precious woodyoilcrop in China. The present study investigated the ameliorative effects of EMO on high-fat diet-induced non-alcoholic fatty liver disease (NAFLD) and explored relative regulation mechanism. The analysis of EMO fatty acids showed that EMO rich in unsaturated fatty acids (92.07%), such as linoleic acid (48.24%), oleic acid (34.20%) and linolenic acid (7.57%). In addition, supplementation of EMO could ameliorate the increase in body weight, fat weight, and abnormal serum lipids induced by high-fat diet. A further important implication is that the levels of serum ALT, serum AST, hepatic TG, TC, SOD, GSH/GSSG ration and MDA were improved after supplementing with EMO. All these changes may be due to the ability of EMO to inhibit fatty acid synthesis via reducing the mRNA expression of SREBP-1c, PPARy and FAS, and elevate fatty acid oxidation by increasing the mRNA expression of PPARa and CPT-1. Meanwhile, our results also showed that endogenously synthesized n-3 PUFAs could significantly increase after treating with EMO. In conclusion, the results suggested that EMO could be regarded as a healthy food for preventing NAFLD.
