Outline of Research at the Start

サーチュイン(哺乳類ではSIRT1-SIRT7)はNAD依存性の脱アセチル化酵素であり、代謝、ストレス応答、老化など様々な生命現象の制御に関与しているが、SIRT7の代謝作用については不明な点が多い。本研究では、SIRT7の糖新生、エネルギー代謝、インスリン分泌における役割を解明し、その分子機構を解明する。またSIRT7の活性測定系を構築し、SIRT7活性を制御する分子の探索を行う。

Outline of Final Research Achievements

Sirtuins (SIRT1-7) are NAD+-dependent lysine deacetylase/deacylases that regulate many biological processes. However, the functional roles of SIRT7 are largely unknown. In the present study, we identified that SIRT7 suppresses energy expenditure by regulating the activity of IMP2, an RNA binding protein that inhibits the translation of Ucp1 mRNA and that SIRT7 knockout mice have increased body temperature and energy expenditure. We have also shown that SIRT7 is a lysine deacylase with a preference for depropionylation and demyristylation. These findings may provide insights into the development of novel SIRT7 modulators for the treatment of obesity and diabetes mellitus.

Academic Significance and Societal Importance of the Research Achievements

肥満や糖尿病を制御する新たな治療方法の開発は、現代社会における重要な医学的課題である。本研究の結果、SIRT7の阻害が代謝異常症の新たなを治療戦略となることが判明した。またSIRT7活性を制御するための基盤となるSIRT7酵素活性の特徴についても明らかにすることができた。
