摘要
微小RNA是真核生物中一类长度约22个核苷酸的小分子非编码RNA,它通过与靶基因的3UTR结合,抑制靶基因翻译或使其降解,实现对靶mRNA转录后水平的调控。微小RNA参与生物体内许多复杂的生理过程,与细胞增殖、分化、凋亡、胚胎发育、血管生成、组织器官形成以及多种疾病的发生发展密切相关。最近的研究表明,微小RNA在内皮细胞参与的血管生成中发挥重要的调控作用,本文将就近年来微小RNA在血管生成调控方面的研究做一综述。
Summary MicroRNAs are the class of small. 22-nucleotides long non-coding RNA in eukaryotes. MicroR- NAs typically control the expression of their target genes in post-transcriptional level for promoting either their degradation or translational repression by imperfect pairing to the 3' untranslated regions. MicroRNAs are involved in the control of a wide range of biological functions including cell development, differentiation, apopto- sis, embryonic development, angiogenesis, tissue and organ formation and development of a lot of diseases. It is increasing evidence that miRNAs play important roles in angiogcnesis in endothelial cells. In this review, we aim at describing the role of miRNAs in angiogenesis.
