Outline of Final Research Achievements

Duchenne muscular dystrophy (DMD), the most common and severe form of muscular dystrophy in childhood, is caused by dystrophin deficiency. Absence of dystrophin has been shown to lead to an increased Ca2+ influx and an abnormal cytosolic Ca2+ homeostasis of myofibers, leading to increased necrosis. Several underlying mechanisms have been suggested to cause this abnormal cytosolic Ca2+ regulation in dystrophic muscle. Therefore, the aim of this study is to identify new therapeutic targets based on cytosolic Ca2+ regulation for DMD. We found that sarcolipin, an intrinsic inhibitory sarcoplasmic reticulum protein of SERCA, is abnormally high in the dystrophic muscle. In this study, we determined the physiological relevance in DMD following loss-of function by sarcolipin gene deletion. Knockdown of SLN ameliorated the cytosolic Ca2+ homeostasis and the dystrophic phenotype in DMD mice model. These findings suggest that SLN may be a novel target for DMD therapy.

Academic Significance and Societal Importance of the Research Achievements

明確な治療法が確立されていないDuchenne型筋ジストロフィーに対して、現在推進されていることは欠失しているジストロフィンを補う・代償することを目指しているが、本研究はそれら方向性とは異なり、細胞内のCa2+動態に着目した研究である。ジストロフィンの補填・代償する治療方法と併用することでより効果的な治療効果が得られることが期待できる。
