Pathogenesis of Non-alcoholic Steatohepatitis and Its Potential Therapeutic Strategies

Non-alcoholic steatohepatitis (NASH) is closely associated with progression to liver cirrhosis and hepatocellular carcinoma. We reported that melanocortin 4 receptor–defi cient mice (MC4R-KO mice), when fed a high-fat diet, provide a novel rodent model of NASH. Recently, we have identifi ed a unique histological feature termed “hepatic crown-like structures” (hCLS) in the livers of MC4R-KO mice...

Cholesterol metabolism and the pathogenesis of non-alcoholic steatohepatitis.

Emerging experimental and human evidence has linked altered hepatic cholesterol homeostasis and free cholesterol (FC) accumulation to the pathogenesis of non-alcoholic steatohepatits (NASH). This review focuses on cellular mechanisms of cholesterol toxicity involved in liver injury and on alterations in cholesterol homeostasis promoting hepatic cholesterol overload in NASH. FC accumulation inju...
