Abstract: Circular RNAs (circRNAs) are single-stranded, covalently closed RNA that were generated by 3' polyA and 5'tail of pre-mRNA via back-splicing. CircRNAs play a crucial role in varieties biological processes. N6-methyladenosine (m6A) is one of the most abundant modifications in eukaryotes, which regulate splicing, translation and degradation of RNA. There is increasing evidence that m6A modification also controlling circRNAs metabolism, including translation, degradation and so on. In this review, the biogenesis and function of circRNAs were summerized. Moreover, the role of m6A modification in the regulation of circRNAs was discussed.

Key words: circRNAs, function, m6A modification
