ABSTRACT
AIM:
To investigate the effects of glucagon-like peptide-1 (GLP-1) on mRNA expression of SOCS-3 and SREBP-1c in the rats with nonalcoholic fatty liver disease.METHODS:
Male SD rats were randomly divided into normal control ( NC) group, high fat ( HF) group and HF+liraglutide ( Lira) group.The rats in HF group and HF+Lira group were given high-fat diet for 16 weeks.After 12 weeks of high-fat diet feeding in HF+Lira group, Lira (600μg? kg-1? d-1 ) was intraperitoneally injected for 4 weeks.At the end of the 16th week, the rats were killed.The pathologi-cal changes of the liver were observed under optical microscope.The serum levels of alanine aminotransferase ( ALT) , as-partate aminotransferase ( AST) , triglyceride ( TG) and total cholesterol ( TC) were detected by automatic biochemical an-alyzer.TG contents of liver were measured by GPO-PAP method.The fasting insulin ( FINS) was determined by ELISA, and insulin resistance index was assessed by homeostasis mode assessment ( HOMA-IR) .The mRNA expression of SOCS-3 and SREBP-1c in the liver tissues was detected by RT-qPCR.RESULTS:
Compared with NC group, HOMA-IR, TG of liver, and the serum levels of ALT, AST, TG, TC and FINS in HF group were obviously increased (P duce TG of liver through decreasing the mRNA expression of SOCS-3 and SREBP-1c, so as to play a therapeutic role in nonalcoholic fatty liver disease.
