| Outline of Final Research Achievements |
Telomerase reverse transcriptase (TERT) is an important molecule that supports high self-proliferative capacity in stem cells. However, epigenetic regulation of tissue-specific expression for the human TERT gene is unknown. In this study, we identified the differentially DNA methylated region of the TERT gene (TERT- DMR), of which hypermethylation enhanced TERT expression. Furthermore, H3K4me3 modification was recognized in human iPS cells, onthe other hand, H3K27me3 modification and HP - 1α binding were significantly recognized in somatic cells. We showed here a new epigenetic mechanism that DNA hypermethylation acts on gene expression.
