From: Emerging role of circular RNAs in the pathogenesis of ovarian cancer
A schematic representation of the effects of some tumor suppressor circRNAs in the progression of ovarian cancer. The sponging effects of tumor suppressor circRNAs on oncogenic miRNAs such as miR-182, miR-32, miR-145 and miR-740 decrease proliferation and induce apoptosis of ovarian cancer cells. Thus, down-regulation of these circRNAs promotes progression of ovarian cancer
