摘要
环状RNA (circular RNA, circRNA)是一类不具有3’端poly(A)和5’端帽子结构的、以共价键首尾相连的单链内源闭合环状RNA。CircRNA具有广泛性、多样性、稳定性和保守性等特点，其具有转录调控和蛋白质翻译等功能。本文从circRNA的生物合成机制、分类、表达、生物学功能、与疾病的关系，以及鉴定与分析方法等方面对近年来的研究进展作一综述，并展望了circRNA的应用前景和研究方向。

Abstract
Circular RNAs (circRNAs) are a class of endogenous, covalently closed, single-stranded RNA without 3’-poly(A) and 5’-cap structures. CircRNAs are characterized by universality, diversity, stability and conservation, and have been found to regulate mammalian transcription and be translated into proteins. In this review, we summarized the biogenesis, classification, expression, distribution, biological functions and regulation of circRNAs. In addition, we discussed the association of circRNAs with diseases and the methods for identification and characterization of circRNAs. Finally, we speculated the application prospect and research direction of circRNAs.


Key words: circular RNAs; biogenesis; function; disease
