Objective To investigate the effects of glucagon-like peptide-1 (GLP-1) receptor agonist, exenatide,on liver function and steatosis in obese mice. Methods Male c57BL/6J mice (8 weeks old) were divided into high-fat-diet group (for obesity model construction) and chow diet group. 12 weeks later, mice of high-fat diet group were randomly divided into high-dose exenatide group 〔H group, intraperitoneal injection 0.02 μg/（g·d）, high-fat-diet〕, low-dose exenatide group 〔L group, intraperitoneal injection 0.01 μg/（g·d）, high-fat-diet〕, saline group （NS group, intraperitoneal injection of saline, high-fat-diet）, diet control group (D group, shifted to chow diet) and high-fat control group (M group, high-fat-diet) for 4-week treatments ,respectively. The body mass and serum biochemical indicators of were detected. Liver tissues were stained with HE, and steatosis score was measured. Results After 4-week treatments, H group showed more body mass loss than L group and D group ( P P
