Core Tip
Core tip: The aim of this study was to examine the protective effects and molecular mechanism of green tea polyphenols (GTP) on non-alcoholic fatty liver disease (NAFLD)-induced by high fat diet (HFD) in genetically obese Zucker fatty (ZF) rats. The data of the study has demonstrated: (1) HFD-ZF rats is an optimal rodent model of NAFLD for testing novel/natural agents for this disease; (2) GTP treatment ameliorated metabolic and histopathological abnormalities in HFD-ZF rats with NAFLD; and (3) GTP exerted a protective effect against hepatic steatosis and liver injury by attenuating inflammatory cytokines and inhibiting lipogenesis through upregulating AMPK activation. Therefore, GTP proves to be an effective natural agent for preventing NAFLD and reducing the risk of its severe complications such as nonalcoholic steatohepatitis, cirrhosis and hepatic cellular carcinoma.
