运动代表着对全身内稳态的一种充满活力的挑战。在骨骼肌中,运动激活了多种信号通路,这些通路最终在细胞核中调节参与代谢和收缩性的基因;然而,关于运动的转录效应物还有很多东西要了解。介体是一种多蛋白复合物,它将信号依赖性转录因子和其他转录调节因子与基础转录机制联系起来,从而充当转录“枢纽”。在这篇文章中,我们讨论了最近的研究强调的作用,调解人亚单位的代谢调节和葡萄糖代谢,以及运动反应。介体亚基在代谢调控中的作用的阐明揭示了调节代谢和代谢紊乱的新机制和分子靶点。
Exercise represents an energetic challenge to whole-body homeostasis. In skeletal muscle, exercise activates a variety of signaling pathways that culminate in the nucleus to regulate genes involved in metabolism and contractility; however, much remains to be learned about the transcriptional effectors of exercise. Mediator is a multiprotein complex that links signal-dependent transcription factors and other transcriptional regulators with the basal transcriptional machinery, thereby serving as a transcriptional “hub.” In this article, we discuss recent studies highlighting the role of Mediator subunits in metabolic regulation and glucose metabolism, as well as exercise responsiveness. Elucidation of the roles of Mediator subunits in metabolic control has revealed new mechanisms and molecular targets for the modulation of metabolism and metabolic disorders.
