CDK6 and ovarian carcinoma: In summary, these data illustrated that circ_0072995 might serve as a ceRNA for miR-147a to regulate CDK6 expression, that circ_0072995 caused abnormal proliferation of ovarian cancer cells, that circ_0072995 reduced apoptosis, and that circ_0072995 may have led to the occurrence and development of EOC (Figure 7).
