Outline of Research at the Start

転写と共役したDNA修復機構 (transcription coupled repair: TCR)は、転写が活発に行われている領域に生じたDNA損傷を効率良く修復するシステムであり、生体の恒常性維持に重要なメカニズムである。本研究では、DNA損傷箇所で停止したRNA合成酵素がユビキチン化修飾を受けてTCRを開始・制御する分子機構の詳細解明に取り組むとともに、TCRの破綻により発症するヒト疾患の病態を明らかにすることを目指す。

Outline of Final Research Achievements

Genomic DNA, which contains our genetic information, is constantly exposed to damage from both internal and external sources. Transcription-coupled repair (TCR) is a system that efficiently repairs DNA damage in actively transcribed regions, playing a crucial role in maintaining homeostasis and preventing genomic instability. In this study, we investigated the molecular mechanisms of TCR and the pathogenesis of human diseases associated with deficiencies in this system. Our research has provided several novel insights into the critical role of TCR in genome maintenance.

Academic Significance and Societal Importance of the Research Achievements

TCRの破綻は、早期老化や進行性の神経変性、好発がん、発育・発達異常などを示す様々な遺伝性疾患の原因となることが知られており、TCRの分子メカニズム解明と各種病態との関係を明らかにすることは、遺伝性疾患のみならず、一般的な老化やがんなどの治療薬/緩和薬/予防薬の開発に役立つだけでなく、新たな診断法の構築やバイオマーカーの探索など、広範囲の医療分野に貢献してゆくと期待される。
