Heart is the first organ to function during mammalian embryogenesis. The differentiation of embryonic stem cells (ESCs) into cardiomyocyte is complex and dynamic, which involves 4 differentiation stages including ESCs, mesoderm, cardiac precursor, and terminal cardiomyocytes. Abnormal expression of certain genes can lead to congenital heart diseases during cardiomyocyte differentiation. Epigenetic regulation plays a crucial role on the switch of gene activation and deactivation during cardiomyocyte differentiation. Non-coding RNA, particularly microRNA and long non-coding RNA, may significantly influence gene expression. Exploring the regulatory roles of non-coding RNA in cardiomyocyte differentiation may contribute to the understanding of the functions of myocardial cells and mechanism of congenital heart diseases.
心脏是哺乳动物胚胎发育过程中第一个发挥功能的器官。胚胎干细胞(ESC)向心肌细胞的分化是复杂且动态的,这一过程涉及4个分化阶段,包括胚胎干细胞、中胚层、心脏前体细胞和终末心肌细胞。某些基因的异常表达可导致心肌细胞分化过程中出现先天性心脏病。表观遗传调控在心肌细胞分化过程中基因激活和失活的转换中起着关键作用。非编码RNA,尤其是微小RNA和长链非编码RNA,可能会显著影响基因表达。探索非编码RNA在心肌细胞分化中的调控作用可能有助于理解心肌细胞的功能以及先天性心脏病的发病机制。
