Outline of Research at the Start

DNA二重鎖切断(DSB)は、放射線によって生じる種々のDNA損傷の中で最も重篤で、放射線の人体影響の鍵を握ると考えられている。DNA依存性プロテインキナーゼ(DNA-PK)はDSBのセンサーと考えられるタンパク質リン酸化酵素である。本研究では、①DSBの形状に応じた修復の制御におけるリン酸化の意義を調べる。②AIを活用した新たなプロテオミクス手法により、新しいDNA-PKの標的やDSB応答現象を探索し、その生理的意義を調べる。本研究は、DNA-PKが何をしているのか、何のために存在するのかを明らかにすること、また、これを通じて放射線治療や放射線防護に資することを目的とする。

Outline of Final Research Achievements

This study aimed to elucidate the biological meaning of the existence of the DNA double-strand break (DSB) sensor molecule, DNA-dependent protein kinase (DNA-PK). This study clarified the effects of phosphorylation by DNA-PK on the function and structure of XRCC4. It also clarified the DNA repair function and the mechanism of the recruitment to DNA damage of XRCC4 binding molecules, PNKP and APTX. Furthermore, it also revealed the reduction in DNA repair function of XRCC4 mutants observed in the patients of microcephaly and growth defect and XRCC4 variant reportedly associated with increased cancer risk. These outcomes of this research might contribute to the improvement of cancer radiotherapy through the prediction and modification of radiosensitivity.

Academic Significance and Societal Importance of the Research Achievements

放射線によって生じるさまざまなDNA損傷の中で、DNA二重鎖切断(DSB)は最も重篤な損傷で、がんの治療効果や副作用の鍵を握ると考えられている。DNA-PKはDSBのセンサーとして働き、DNA修復をはじめとする種々の細胞応答を引き起こすために重要と考えられる。本研究は、DSBの結合を制御するXRCC4に注目し、これまで長年の研究にも関わらず明らかになっていなかったDNA-PKのDSB修復における機能や存在意義の一端を明らかにした。本研究の成果は、放射線感受性の予測や制御を通じてがん放射線治療のさらなる向上につながる可能性が期待される。
