摘要微小RNA(microRNA,miRNA)是一类长度为21~25nt的非编码小RNA,可与其靶基因的3’端非编码区互补结合,直接降解靶基因或抑制其编码蛋白质的翻译,广泛参与发育、代谢、凋亡以及多种疾病过程.研究表明,miRNA在缺血性卒中的发生和发展过程中发挥着重要作用,并参与了卒中后的保护和修复机制的调控.

abstractsmicroRNAs (miRNAs) are a class of small non-coding RNAs (length 21 to 25 nt).They can complement and bind to 3' non-coding region of their target genes,directly degrade target genes or inhibit the translation of encoding proteins,and extensively participate in development,metabolism,apoptosis,and a variety of disease processes.Studies have shown that miRNAs play important roles in the occurrence and development of ischemic stroke,and participate in post-stroke protection and regulation of repair mechanisms.
