增加活性氧(ROS)的产生是至关重要的重塑发生在骨骼肌中的运动训练和长时间的废用。这篇综述讨论了负责这种ROS诱导的骨骼肌适应的氧化还原敏感的信号通路。我们开始与骨骼肌纤维的活性氧生产的网站的讨论。随后概述了促进骨骼肌适应的假定氧化还原敏感信号通路。具体来说,本讨论强调氧化还原敏感激酶,磷酸酶和转录因子核因子-κB。我们还讨论了证据,连接氧化还原信号的骨骼肌适应增加肌肉活动(即运动训练),并在长时间的肌肉不活动(即固定)。为了促进进一步的研究,我们最后讨论了骨骼肌中氧化还原信号的未回答的问题。
Increased reactive oxygen species (ROS) production is crucial to the remodelling that occurs in skeletal muscle in response to both exercise training and prolonged periods of disuse. This review discusses the redox-sensitive signalling pathways that are responsible for this ROS-induced skeletal muscle adaptation. We begin with a discussion of the sites of ROS production in skeletal muscle fibres. This is followed by an overview of the putative redox-sensitive signalling pathways that promote skeletal muscle adaptation. Specifically, this discussion highlights redox-sensitive kinases, phosphatases and the transcription factor nuclear factor-κB. We also discuss the evidence that connects redox signalling to skeletal muscle adaptation in response to increased muscular activity (i.e. exercise training) and during prolonged periods of muscular inactivity (i.e. immobilization). In an effort to stimulate further research, we conclude with a discussion of unanswered questions about redox signalling in skeletal muscle.
