Outline of Final Research Achievements

Hydrogen sulfide was detected in mammalian brain in 1989. Thus, it has become recognized as a gasotransmitter such as nitric oxide (NO) and carbon monoxide (CO). Although skeletal muscle atrophy cause a decrease in QOL (Quality of life), effective treatment for skeletal muscle atrophy has not still been established. In this study, I elucidated that hydrogen sulfide contribute to the muscle hypertrophy in a mouse skeletal muscle cell line. I further found that cysteine contribute to the muscle hypertrophy.

Academic Significance and Societal Importance of the Research Achievements

寝たきりによる骨格筋萎縮はQOL(クオリティオブライフ)を著しく低下させ、医療費の増大につながっている大きな社会問題である。その治療法はリハビリに頼っているところが大きく、負担の少ない治療法の開発が必須である。本研究ではガス状生理活性物質である硫化水素による骨格筋肥大効果を初めて明らかにした。さらにその生体内供与体のアミノ酸であるシステインによる筋肥大効果も見出したことから、栄養成分(または食品)による骨格筋萎縮の治療法の第一歩となることが期待される。
