Research Abstract

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in developed countries, and its incidence is increasing in adults and children. As an antioxidant, vitamin E is effective in treatment of NAFLD, although the mechanism is still unclear. Methionine-choline deficient (MCD) rats used as an experimental model of NAFLD were fed a vitamin E-enriched diet. In the MCD rats, vitamin E treatment altered the hepatic alpha-tocopherol-related protein expression, which may affect the alpha-tocopherol status in the liver and reduce lipid peroxidation.
