MicroRNA(miRNAs)是一种含有18-25个核苷酸的小RNA分子。其表达水平的改变在包括心脏病在内的许多疾病的发展中起着至关重要的作用。心肌重构是多种心肌疾病的最终病理结果。miRNAs通过多种机制调节心肌肥大、心肌细胞损伤、心肌纤维化、血管生成和炎症反应,在心肌重塑的发病机制中发挥重要作用。不同miRNA的平衡和紧密调节是驱动细胞事件朝向功能恢复的关键,并且在此的任何下降导致在各种损伤之后对心脏功能的有害影响。本文就miRNAs表达改变对心肌肥厚、心肌细胞损伤、心肌纤维化、血管生成和炎症反应的影响作一综述。我们还描述了靶点(受体、信号分子、转录因子等)。在心脏组织的不同类型细胞中,它们作用于其上以促进或减弱心脏重塑过程。
MicroRNAs (miRNAs) are small RNA molecules that contain 18–25 nucleotides. The alterations in their expression level play crucial role in the development of many disorders including heart diseases. Myocardial remodeling is the final pathological consequence of a variety of myocardial diseases. miRNAs have central role in regulating pathogenesis of myocardial remodeling by modulating cardiac hypertrophy, cardiomyocytes injury, cardiac fibrosis, angiogenesis, and inflammatory response through multiple mechanisms. The balancing and tight regulation of different miRNAs is a key to drive the cellular events towards functional recovery and any fall in this leads to detrimental effect on cardiac function following various insults. In this review, we discuss the impact of alterations of miRNAs expression on cardiac hypertrophy, cardiomyocytes injury, cardiac fibrosis, angiogenesis, and inflammatory response. We have also described the targets (receptors, signaling molecules, transcription factors, etc.) of miRNAs on which they act to promote or attenuate cardiac remodeling processes in different type cells of cardiac tissues.
