| Outline of Final Research Achievements |
We have identified a novel PTEN-binding NDRG2 tumor suppressor gene from the genome analysis of adult T-cell leukemia Isolated as a protein and used for the regulation of PTEN activity by PP2A-mediated dephosphorylation of PTEN NDRG2 has been implicated in the pathogenesis of multiple cancers and has been shown to play a key role in the development of new HSP 90/PRMT5 complex. In particular, down-regulation of PRMT5 expression caused HSP90 dysfunction in ATL/cancer cells and reduced AKT The degradation and apoptosis of many Client proteins, including NDRG2 Therefore, NDRG2-deficient cancer cells show abnormalities in phosphorylation and arginine methylation, and cancer cells It is suggested that this is associated with a specific increase in HSP90 activity.

この研究ではNDRG2癌抑制遺伝子機能異常を中心に研究を行っており、NDRG2異常をきたす癌・白血病におけるタンパク質リン酸化、メチル化修飾異常を網羅的に明らかしている。、その中心として新たながん細胞特異的HSP90の新規活性調節機構としてPRMT5によるアルギニンメチル化を同定した。この発癌機構を基礎とした新規治療薬の開発へつながる重要な研究である。
