Outline of Research at the Start

本研究では、DNA修復欠損がんを対象とした新たな診断・ 治療法の開発に挑む。具体的には、応募者が発見したDNA組換えのメカニズムをベースに (Nature Commun., 2017)、標的細胞でのみ遺伝子発現を起こす系を理論的に構築し、その効果を幅広く検証する。こうして得られた成果は、正確で迅速なDNA修復能評価法だけでなく、副作用の小さいがん治療の開発につながると期待され、今後がん治療分野全般、特に個別化医療の高度化に向けて有益となる。

Outline of Final Research Achievements

In this research project, an extensive number of DNA constructs were systematically constructed to develop novel strategies for assessing the state of DNA repair in cultured cells and tumor tissues. Using these constructs, we have succeeded in rapidly detecting the cellular status of homologous recombination and mismatch repair, which act as guardians of the human genome.

Academic Significance and Societal Importance of the Research Achievements

DNA修復機構の異常は悪性腫瘍全体の25%以上にみられる。本研究の成果は、特定の悪性腫瘍におけるDNA修復の状態を正確に判定するための基盤技術となり、適切な化学療法を選択するための正しい判断基準の提供につながると期待できる。
