title: Scopoletin prevents alcohol-induced hepatic lipid accumulation by modulating the AMPK-SREBP pathway in diet-induced obese mice.
abstract: OBJECTIVE
  This study investigated the effects of scopoletin on alcohol-induced hepatic lipid accumulation in diet-induced obese mice and its mechanism.
  
  
  METHODS
  Alcohol (25% v/v, 5g/kg body weight) was orally administered once a day for 6 weeks to mice fed with a high-fat diet (35%kcal) with or without scopoletin (0.05%, wt/wt).
  
  
  RESULTS
  Scopoletin reduced plasma acetaldehyde, fatty acid, total cholesterol, triglyceride and insulin levels, hepatic lipid and droplets and fasting blood glucose levels that were increased by alcohol. Scopoletin significantly activated hepatic AMPK and inhibited ACC and SREBP-1c and the activities of lipogenic enzymes, such as FAS, PAP and G6PD compared to the alcohol control group. Moreover, scopoletin significantly inhibited hepatic CYP2E1 activity and protein levels but elevated the activities of SOD, CAT, GSH-Px and GST and the levels of GSH compared to the alcohol control group. The hepatic lipid peroxide level was significantly lowered by scopoletin supplementation in alcohol-administered obese mice.
  
  
  CONCLUSIONS
  Taken together, these results suggested that scopoletin can ameliorate alcohol-induced hepatic lipid accumulation by modulating AMPK-SREBP pathway-mediated lipogenesis in mice fed a high-fat diet.
