Outline of Final Research Achievements |
Endurance exercise training and calorie restriction suppress the development of atherosclerosis. Considering that characteristic changes of skeletal muscle are involved in this mechanism, we focused on the transcription factors PGC-1α and FOXO-1 that cause the changes of muscles due to exercise and energy restriction. In this study, we focused on skeletal muscle-specific PGC-1α or FOXO-1 overexpression on the progression of atherosclerosis was investigated. As a result, overexpression of skeletal muscle-specific PGC-1α or FOXO-1 suppresses the progression of atherosclerosis. The physiology of bioactive substances secreted from skeletal muscle, such as β-aminoisobutyric acid and Irisin, might be involved in the suppression.

Academic Significance and Societal Importance of the Research Achievements |
本研究により、持久運動トレーニングとエネルギー制限による動脈硬化進展抑制機序の一端を、PGC-1αやFOXO-1といった骨格筋機能に着目して明らかにした。本研究で得られた成果により、骨格筋から分泌される生理活性物質(マイオカイン)に着目した動脈硬化を予防するためのバイオマーカー開発や、マイオカインを豊富に含む食品を摂取することによる動脈硬化性疾患の予防法開発に発展する可能性がある。
