摘要: microRNA(miRNA)是一类广泛存在于动植物的由19~25个核苷酸组成的具有高度保守性的单链非编码RNA,其生物学效应是通过与mRNA互补配对在转录后水平负调控靶基因的表达。肠缺血再灌注(I/R)损伤在临床实践中较为常见,缺血再灌注后会导致肠黏膜屏障损伤,且与临床上众多疾病的发生、发展与转归都有一定的联系。目前有众多研究显示,miRNA的亚型基因miR-34a-5p、miR-351-5p、miR-682、miR-21等在一定程度上通过调控一系列信号转导进而影响肠I/R损伤的发生、发展。因此,揭示miRNA在肠I/R损伤中作用机制,并可为肠I/R损伤的临床诊断及治疗提供新的方向。

Abstract: microRNA (miRNA) is a class of 19-25 nucleotide highly conserved single-stranded non-coding RNA that is widely found in plants and animals. Their biological effect is to negatively regulate target gene expression at the post-transcriptional level through complementary pairing with mRNA. Intestinal I/R injury is more common in clinical practice, and ischemia-reperfusion will cause intestinal mucosal barrier damage, and it is related to the occurrence, development, and outcome of many clinical diseases. Many studies have shown that the miRNA subtype genes miR-34a-5p, miR-351-5p, miR-682, miR-21, etc. affect the intestinal I/R injury process to some extent by regulating a series of signal transduction. Therefore, revealing the role of miRNA in intestinal I/R injury and providing a new direction for the diagnosis and treatment of I/R.

Key words: miRNA, ischemia-reperfusion injury, intestinal injury, intestinal protection
