Outline of Final Research Achievements

Adult T-cell leukemia/lymphoma (ATL), an aggressive type of T-cell malignancy, is induced by human T-cell leukemia virus type I (HTLV-1) infection. The outcomes, following therapeutic interventions for ATL, have not been satisfactory. In the present investigation, we established live-cell imaging method of DNA methylation using methylated DNA binding protein (MBD) fused with enhanced green fluorescent protein (EGFP); MBD-EGFP to detect dynamic changes of DNA methylation induced by endogenous and/or exogenous environmental perturbations in human leukemia cells. Comprehensive global DNA methylation and gene expression analyses revealed dynamic changes of target gene methylation and gene expression followed by HTLV1tax gene expression. In vitro live cell imaging of DNA methylation with HTLV-1tax-oncogene ON/OFF system is useful system to investigate epigenetic mechanism of ATL leukemogenesis/lymphomagenesis.

Academic Significance and Societal Importance of the Research Achievements

我々はこれまでに超微量検体を用いて造血器腫瘍のDNA異常メチル化を高感度・高精度に検出する方法を開発し、造血器腫瘍の早期診断、また低悪性度から高悪性度病型への進展可能性を評価する検査方法の開発に成功した。本研究に於いてlive cell imaging法を用いてHTLV-1tax癌遺伝子発現がDNA異常メチル化を誘発し遺伝子発現異常を引き起こすことを直接示し、そのダイナミックスを解析した。DNA異常メチル化誘発機構と発癌との関連を明らかにすることは、エピジェネテイック制御が可逆的であることから将来悪性腫瘍の新規早期発見・早期治療法更に予防法につながる可能性があり,さらなる発展が期待される。
