| Outline of Final Research Achievements |
Fatty liver has been recognized not only as a complication of metabolic syndrome but also as a causative factor of steatohepatitis, liver cirrhosis and hepatocellular carcinoma. However, the mechanism how fatty liver progresses to steatohepatitis is not fully understood. Our study was aimed at elucidating the role of lipases in fatty liver and suggested that increased hydrolysis of cholesterol ester and production of free cholesterol in liver may promote inflammation in fatty liver. The exact molecular mechanism is under further investigation.
