    The study identifies differential circular RNAs (circRNAs) in goat ovarian follicles that may play crucial roles in follicular development. Specifically, the novel gene circCFAP20DC is highlighted for its ability to activate the RB pathway, which facilitates the transition of granulosa cells (GCs) from the G1 to S phase. This activation promotes the proliferation of follicular GCs, suggesting a significant biological function of circCFAP20DC in the development of goat follicles.
