摘要

微RNA(microRNA, miRNA)是新发现的一类进化上高度保守的重要的转录后调控因子, 通过调节基因的表达而参与调控细胞凋亡、增殖及分化等生理过程, 同时与肿瘤等疾病的发生发展密切相关。近年来研究发现, miRNA、miRNA生物合成通路基因及miRNA的靶基因结合位点的遗传变异(例如单核苷酸多态性和拷贝数变异等)可影响miRNA调控功能的发挥, 并产生显著的遗传学效应。文章主要综述了miRNA相关的遗传变异与肿瘤易感性和临床转归等的研究进展。

Abstract

microRNAs (miRNAs) are a highly conserved class of small noncoding RNAs that regulate gene expression by post-transcriptional degradation or translational repression. miRNAs are involved in the regulation of cell apoptosis, prolif-eration, differentiation and other physiological processes, and are closely related with the development of cancer. More recently, it has been proposed that the presence of genetic variations (e.g., single nucleotide polymorphism and copy num-ber variation) in microRNA genes, their biogenesis pathway and target binding sites affect the miRNA processing machin-ery and targeting, and have a significant genetic effect. In this review, we focus on the miRNA-related genetic variations and cancer susceptibility and progression.
