Skeletal muscle development and growth regulatory mechanism is the focus of both animal genetics and medicine. The recent studies indicate that covalently closed circular RNAs (circRNAs) also play important role on muscle development through sequestering specific miRNAs. The present study was conducted to determine the functional roles of circZfp609, a recently identified circRNA, in the regulation of myogenesis in mouse myoblast cell line (C2G12). circZfp609 is predicted to has binding sites of miR-194-5p. circZfp609 knockdown increased the expression of MyfS and MyoG, which indicated that circZfp609 suppressed myogenic differentiation. Via a luciferase screening assay, circZfp609 is observed to sponge to miR-194-5p with four potential binding sites. Specifically, we show that circZfp609 can sponge miR-194-5p to sequester its inhibition on BCLAF1 so as to repress the myogenic differentiation. Modulation of circZfp609 expression in muscle tissue may emerge as a potential target in breeding strategies attempting to control muscle development. (C) 2018 Published by Elsevier B.V.
