Outline of Final Research Achievements

Promotion of skeletal muscle regeneration is important from the viewpoint of treating muscle diseases and preventing disuse muscle atrophy in the elderly. We have reported that calpain and urokinase play an important role in skeletal muscle regeneration. In this study, we focused on TRPV1, one of the transient receptor potential (TRP) channel families. TRPV1 is reported to be involved in the transmission of sensory stimuli, such as pain stimuli, and this time, by applying myoblast proliferation, we aimed to develop a biomarker that predicts muscle regeneration. Furthermore, we established a rehabilitation training method to prevent muscle atrophy and contributed to the prevention of sarcopenia, which is a problem in an aging society.

Academic Significance and Societal Importance of the Research Achievements

申請者らは、Transient receptor potential(TRP)チャンネルファミリーのひとつのTRPV1に注目し、各種筋疾患や筋損傷モデルマウスの生検筋を用いて病理学的、生化学的、分子生物学的に手法にてTRPV1のバイオマーカーをとしての有用性を検討した。そして、筋萎縮モデルにTPPV1アゴニストを投与し、筋萎縮予防効果を検討した。骨格筋再生のバイオマーカーの探索は、筋疾患や廃用による筋萎縮を予防し、筋再生を促す治療法を確立することにある。
