心肌和骨骼肌的发育由进化上保守的转录因子网络控制,这些转录因子协调参与肌肉生长、形态发生、分化和收缩性的基因的表达。除了调节蛋白质编码基因的表达外,最近的研究还表明,生肌转录因子控制一组 microRNA 的表达,这些 microRNA 通过多种机制发挥作用,调节肌肉发育和功能。在某些情况下,microRNA 可以微调目标 mRNA 的表达,而在其他情况下,它们起着“开关”的作用。 MicroRNA 对基因表达的控制似乎在心血管和骨骼肌疾病期间尤其重要,其中 microRNA 参与横纹肌组织的应激依赖性重塑。我们回顾了肌肉发育和疾病过程中 microRNA 介导的基因表达控制重要性的研究结果,并考虑了 microRNA 作为治疗靶点的潜力。
Cardiac and skeletal muscle development are controlled by evolutionarily conserved networks of transcription factors that coordinate the expression of genes involved in muscle growth, morphogenesis, differentiation, and contractility. In addition to regulating the expression of protein-coding genes, recent studies have revealed that myogenic transcription factors control the expression of a collection of microRNAs, which act through multiple mechanisms to modulate muscle development and function. In some cases, microRNAs fine-tune the expression of target mRNAs, whereas in other cases they function as “on-off” switches. MicroRNA control of gene expression appears to be especially important during cardiovascular and skeletal muscle diseases, in which microRNAs participate in stress-dependent remodeling of striated muscle tissues. We review findings that point to the importance of microRNA-mediated control of gene expression during muscle development and disease, and consider the potential of microRNAs as therapeutic targets.
