| Outline of Final Research Achievements |
The aim of this study is the identification of biomarkers to predict HCC development after successful treatment of viral hepatitis. By the methylation and gene expression analysis, we identified that gene X mainly expressed in endothelial cells and could be a potential biomarker for HCC. Interestingly, gene X was induced by ER stress and shear stress in cultured endothelial cells, in addition, over expression of gene X induced inflammatory cytokines such as IL1B, IL6 and IL8. Gene X enhanced tumor formation in xenograft tumor model in NOD/SCID mice. Moreover, high expression of gene X was associated with poor progression free survival and over whole survivals. Therefore, the expression of gene X was useful biomarker for the prediction of HCC after successful therapy for viral hepatitis.
