Outline of Final Research Achievements

The action mechanisms of caloric restriction (CR), which retards the onset of age-related pathology and extends the lifespan, include the activation of mitochondrial function in white adipose tissue. The present study elucidated the association of MIPEP with mitochondrial function and the qualitative alterations in white adipose tissue.

Academic Significance and Societal Importance of the Research Achievements

CR による抗老化作用は、人類にとって魅力的なものであるが、実際に実験動物で行われているような長期間のCR を実践することは難しい。それゆえ、その作用の分子メカニズムの模倣は効果的な抗老化治療につながり得る。本研究の成果により、未だ不明な点の多いMtシグナルペプチダーゼの学術的な知見を取得するとともに、MIPEPを新たなCR模倣対象として提唱するに至った。
