Outline of Final Research Achievements

Methylation profiles of hepatocellular carcinoma (HCC) have revealed aberrant hypermethylation and hypomethylation, which form four subgroups. However, molecular significance of aberrant hypomethylation in HCC remains poorly understood. Here, we performed comprehensive profiling of cytosine methylation and hydroxymethylation (5-hmC) for the TET1-upregulated HCCs and clarified the aberrant deposition of 5-hmC in a genome-wide manner. Knockdown of endogenous TET1 in hepatoma cell lines decreased hmC deposition with cell growth suppression. Collectively, these results indicate the novel function of methylcytosine dioxygenase TET1 that promotes cell proliferation though epigenetic dysregulation of the oncogenic targets during hepatocarcinogenesis.
