Asiatic acid ameliorates hepatic lipid accumulation and insulin resistance in mice consuming a high-fat diet.
2014
Effects of asiatic acid (AA) at 10 or 20 mg/kg/day upon hepatic steatosis in mice consuming a high-fat diet (HFD) were examined. AA intake decreased body weight, water intake, feed intake, epididymal fat, and plasma and hepatic triglyceride levels in HFD-treated mice (P < 0.05). HFD enhanced 2.85-fold acetyl coenzyme A carboxylase (ACC1), 3.34-fold fatty acid synthase (FAS), 3.71-fold stearoyl CoA desaturase (SCD)-1, 3.62-fold 3-hydroxy-3-methylglutaryl coenzyme A reductase, 2.91-fold sterol regulatory element-binding protein (SREBP)-1c, and 2.75-fold SREBP-2 expression in liver (P < 0.05). Compared with HFD groups, AA intake at two doses reduced 18.9–45.7% ACC1, 25.1–49.8% FAS, 24.7–57.1% SCD-1, and 21.8–53.3% SREBP-1c protein expression (P < 0.05). Histological results indicated AA intake at two doses reduced hepatic lipid accumulation and inflammatory infiltrate. HFD increased hepatic production of reactive oxygen species, interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, as well as decreased hep...
