| Research Abstract |
Non-alcoholic steatohepatitis(NASH) is considered a hepatic phenotype of metabolic syndrome and at high risk for the progression to cirrhosis and hepatocellular carcinoma. The molecular mechanisms are still unclear partly because of no appropriate animal models that reflect a liver condition similar to human NASH. In this study, we showed that MC4R-KO mice on a high-fat diet would provide a novel mouse model of NASH with which to investigate the sequence of events that comprise diet-induced hepatic steatosis, liver fibrosis, and hepatocellular carcinoma. Using this mouse model, we found changes in macrophage distribution and function during the course of NASH development.
