It is reported herein that certain muscle diseases and conditions, including forms of muscular dystrophy, are characterized by impaired insulin-dependent signaling in the muscle tissue, in essence, a form of insulin resistance. The present disclosure relates to therapeutic agents, compositions and methods for treating a muscle disease or condition characterized by impaired insulin-dependent signaling by targeting components of the defective insulin signaling pathway. The disease or condition may be treated by administering a therapeutic agent that activates the insulin signaling pathway, in particular, therapeutic agents that act post-insulin receptor to modulate intracellular effector molecules. An exemplary modulator is metformin. Metformin may be administered alone or may be coadministered with another therapeutic agent for treating the muscle disease or condition, such as a corticosteroid.
本文报道了某些肌肉疾病和情况,包括肌肉萎缩症的形式,其特征是肌肉组织中的
胰岛素依赖性信号传导受损,本质上是一种
胰岛素抵抗形式。本公开涉及治疗剂、组合物和方法,用于通过针对缺陷的
胰岛素信号途径的组分来治疗被
胰岛素依赖性信号传导受损所特征的肌肉疾病或情况。可以通过给予激活
胰岛素信号途径的治疗剂来治疗疾病或情况,特别是作用于
胰岛素受体后来调节细胞内效应分子的治疗剂。一个示例调节剂是
二甲双胍。
二甲双胍可以单独给予,也可以与用于治疗肌肉疾病或情况的另一种治疗剂如皮质类
固醇一起联合给予。
