Compositions and methods for modulating HIF-2α to meditate of hypoxia signaling in satellite cells and applications thereof for improving skeletal muscle generation and repair are provided. For example, methods of enhancing, increasing, accelerating or/and otherwise improving skeletal muscle generation or regeneration in a subject in need thereof are disclosed. In some embodiments, the methods include administering the subject an effective amount of HIF-2α inhibitor. The HIF-2α inhibitor can be effective to, for example, increase muscle satellite cell proliferation, differentiation, or a combination thereof in a subject. Composition and methods for improving respiration, and reducing or preventing the development or progression of fibrosis are also provided. The disclosed compositions and methods are particularly useful for treating muscular dystrophies, myopathies, and other muscle-related diseases and disorders.
本研究提供了调节 HIF-2α 以调解卫星细胞中缺氧信号传导的组合物和方法及其在改善骨骼肌生成和修复中的应用。例如,公开了增强、增加、加速或/和以其他方式改善有需要的受试者的骨骼肌生成或再生的方法。在一些实施方案中,这些方法包括向受试者施用有效量的 HIF-2α 抑制剂。例如,HIF-2α抑制剂可有效增加受试者体内肌肉卫星细胞的增殖、分化或其组合。还提供了用于改善呼吸、减少或预防纤维化的发生或发展的组合物和方法。所公开的组合物和方法特别适用于治疗肌肉萎缩症、肌病和其他肌肉相关疾病和失调。
