摘要: 最新研究表明,RNA之间可以通过竞争结合共同的microRNA反应元件(microRNA response element, MRE)实现相互调节,这种调控模式构成竞争性内源RNA(Competing endogenous RNA, ceRNA)。已发现的ceRNA包括蛋白编码mRNA和非编码RNA,其中后者包括假基因转录物、长链非编码RNA(Long non-coding RNA, lncRNA)、环状RNA(Circular RNA, circRNA)等。文章主要从ceRNA分类的角度,阐述各类ceRNA构成的调控网络发挥的生物学功能在病理和生理相关过程中的作用,以及可能影响ceRNA调控有效性的因素。

Abstract: Recent studies demonstrate that RNA species could regulate each other by competing for shared microRNA response elements (MREs). This regulatory model is called competing endogenous RNA (ceRNA). Currently, the identified ceRNAs cover coding and non-coding RNAs. The latter includes pseudogene transcripts, long non-coding RNAs (lncRNAs), circular RNAs (circRNAs) and so on. In this review, we summarize the biological functions of regulatory networks consisting of various types of ceRNAs and their roles in the pathological and physiological processes. Additionally, several factors that may regulate ceRNAs were discussed.

Key words: competing endogenous RNA, microRNA response element, pseudogene, long non-coding RNA, circular RNA
