摘要 非编码RNA(ncRNA)占哺乳动物RNA的98%,既往认为非编码RNA不具备生物学功能,但近些年来的研究发现,非编码RNA可从表观遗传学、转录调控及转录后调控等多个层面实现对基因表达的调控,其表达水平的变化与多种疾病密切相关,亦影响到心血管疾病的发病进程。其中,长链非编码RNA(lncRNA)成为基因组学研究中一颗冉冉升起的新星,其可从转录水平调控疾病相关基因的表达,亦可竞争性结合microRNA,以影响目的基因的表达和功能。文章从非编码RNA的来源、分类、作用机制及lncRNA在心血管疾病中的研究进展进行综述。具有细胞和组织特异性的lncRNA未来则有望成为一类全新的疾病诊断、判断预后的特异标志物和新药作用靶点,为疾病的临床诊断与治疗提供新思路。
