Outline of Research at the Start

遺伝性早老症であるウェルナー症候群は、思春期以降に様々な老化徴候が出現し、促進されるため、ヒトにおける老化のモデル疾患として注目されている。糖尿病、動脈硬化、悪性腫瘍などを若年で高率に発症するが、その早期老化病態の背景にある機序は不明である。申請者はこれまで、複数のWS患者からiPS細胞を樹立、ゲノム編集技術を用いて原因遺伝子WRNの遺伝子修復を行い、分化細胞において早期老化が抑制されることを見出した。本研究では、核酸代謝を中心とした代謝物の変化が、WSの早期老化徴候に与える影響を明らかにし、一般老化と共通する新規老化機序の解明並びに抗老化治療開発への足がかりとする。

Outline of Final Research Achievements

The aim of this study was to elucidate the relationship between premature aging symptoms and metabolic abnormalities in Werner syndrome (WS) by revealing the metabolomic expression profile in WS. To date, we have established iPS cell lines from somatic cells of eight WS patients by introducing the Yamanaka four factors, and we have established iPS cell lines with the WRN gene, the causative gene, repaired using CRISPR/Cas9 (Kato H. Stem Cell Res. 2021). By inducing these cells to differentiate into MSCs and by further analysis, it has become clear that abnormalities in nucleic acid metabolism in WS impact premature aging phenotypes. We aim to further develop our understanding of the pathology and potential therapeutic approaches in WS.

Academic Significance and Societal Importance of the Research Achievements

本研究ではWSの核酸代謝異常が早期老化症候に与える影響を初めて明らかにした。WSは種々の老化関連代謝疾患を合併するため、WSにおける代謝物の変化を探求することは、老化そのものへの理解につながると考えられ、今後、一般老化と共通する新規老化機序の解明並びに抗老化治療開発への足がかりとなると期待される。
