Outline of Research at the Start

長鎖ノンコーディングRNA(lncRNA)は,タンパク質に翻訳されない全長200塩基以上のRNAであり,多様な生命現象に関与することが報告されている.骨格筋においては,いくつかのlncRNAが骨格筋細胞の増殖や分化を調節することが明らかにされているが,骨格筋の持久性運動適応における役割について検討した報告はない.そこで本研究では,網羅的な変動遺伝子解析や生体骨格筋における機能的スクリーニング,さらにはlncRNAの発現を操作した遺伝子改変マウスを用いた解析から,骨格筋の運動適応におけるlncRNAの生理機能を明らかにすることを目的とする.

Outline of Final Research Achievements

The purpose of this study was to clarify the function of long non-coding RNAs (lncRNAs) in skeletal muscle adaptation to endurance exercise. Based on our RNA-seq analysis using the gastrocnemius muscle following exercise training, we identified 16 exercise-inducible lncRNAs whose functions have not yet been determined. To address the function of these lncRNAs, we manipulated their expression and evaluated citrate synthase (CS) activity as a marker of mitochondrial volume in adult skeletal muscle. Knockdown of an lncRNA in the tibialis anterior muscle of PGC-1α Tg mice, which mimics the effects of skeletal muscle exercise, resulted in a significant decrease in CS activity. This suggests that this lncRNA could be a novel regulator of mitochondrial volume in skeletal muscles.

Academic Significance and Societal Importance of the Research Achievements

長鎖ノンコーディングRNA(lncRNA)は新たな機能性RNA分子として注目されているが,その生理機能はほとんど明らかでない.またこれらのRNAはがんをはじめとするさまざまな疾患の治療標的となる可能性がある.本研究は,骨格筋の運動適応に関与する新たなlncRNAを同定し,その生理機能を明らかにすることで代謝性疾患の治療標的の開発へ繋がることが期待される.
