| Outline of Final Research Achievements |
The prevalence of non-alcoholic fatty liver disease (NAFLD) has increased. Non-alcoholic steatohepatitis (NASH) shows progression of liver fibrosis in NAFLD. NASH os characterized by presence of ballooned hepatocyte. We revealed that signaling of cell death and impaired autophagic process were associated with morphological and biochemical similarity of ballooned hepatocyte. We also found the presence of ballooned hepatocytes was a risk factor for the progression of liver fibrosis in clinical study. The present project demonstrated that ballooned hepatocyte might be therapeutic target of NASH.
