心脏比任何其他器官都更需要在生物体的整个生命周期中以秒到秒的基础上精确地发挥作用。即使心脏结构或功能的微小扰动也会造成灾难性的后果,导致致命的先天性和成人心脏病。心脏对变异性的这种不耐受需要特别强大的调控机制来管理心脏基因的表达。最近的研究揭示了microRNAs(MiRNAs)在心血管发育和疾病过程中作为基因表达调控因子的核心作用。MiRNAs整合到心脏的遗传回路中,提供了一系列丰富而强大的调控相互作用来控制心脏基因的表达。MiRNA调控网络还提供了通过操纵致病和保护性miRNAs来治疗调节心脏功能的机会。我们讨论了miRNAs作为心脏形态和功能调节器的作用,该领域尚未解决的问题,以及未来的问题。
The heart, more than any other organ, requires precise function on a second-to-second basis throughout the lifespan of the organism. Even subtle perturbations in cardiac structure or function have catastrophic consequences, resulting in lethal forms of congenital and adult heart disease. Such intolerance of the heart to variability necessitates especially robust regulatory mechanisms to govern cardiac gene expression. Recent studies have revealed central roles for microRNAs (miRNAs) as governors of gene expression during cardiovascular development and disease. The integration of miRNAs into the genetic circuitry of the heart provides a rich and robust array of regulatory interactions to control cardiac gene expression. miRNA regulatory networks also offer opportunities for therapeutically modulating cardiac function through the manipulation of pathogenic and protective miRNAs. We discuss the roles of miRNAs as regulators of cardiac form and function, unresolved questions in the field, and issues for the future.
