摘要 微小RNA(miRNA)是一种高度保守的单链小分子RNA,具有调控组织细胞的生长发育、分化以及凋亡的作用。let-7 miRNA家族是目前研究最为广泛的miRNA家族。let-7能够在人体外周血以及体液中稳定存在,其表达以及平衡状态的维持受到调控因子的相关作用来实现。这些调控通路的异常将导致let-7家族的表达异常,就从而导致肿瘤,高血压,癫痫,心血管等疾病的发生。因此,监测let-7表达水平可预防、治疗与其相关的疾病。本文主要综述了miRNA let-7对这些疾病的调控机制的研究进展。

Abstract :MicroRNA (miRNA) is a highly conserved single-stranded small molecule RNA, which can regulate the growth, development, differentiation and apoptosis of histocytes. The let-7 miRNA family is currently the most widely studied family of miRNAs. Let-7 can be stably present in human peripheral blood and body fluids, and its expression and maintenance of equilibrium state are achieved by the relevant effects of regulatory factors. Abnormalities in these regulatory pathways lead to abnormal expression of the let-7 family, which leads to the development of tumors, hypertension, epilepsy, and cardiovascular diseases. Therefore, monitoring the expression level of let-7 can prevent and treat diseases associated with it. This review focuses on the research progress of miRNA let-7 on the regulation of these diseases.
