Abstract: Circular RNA (circ-RNA) is a class of closed circular RNA molecules formed by reverse splicing of the initial transcriptional RNA, which are expressed abundantly in eukaryocytic cells. circ-RNA exists stably for a long period because of the resistance to RNA exonuclease. The expression of genes is regulated by cornpetitive binding of miRNA via sponge absorption. Recent studies demonstrated that circ-RNA molecular identification and physiological regulation had become the focus of life science research. In this review, we summarized the biogenesis of circ-RNA, the role in regulating early embryonic development, and the quantity and effects during the gamete development.

Key words: circ-RNA, formation, reproductive development, gene expression
