Aim: This study aimed to investigate the influence of circular RNA PVT1 (circ-PVT1) on epithelial ovarian cancer (EOC) cell proliferation and apoptosis, more importantly, to identify the target microRNAs (miRNA) of circ-PVT1 in EOC. Methods: Circ-PVT1 expression in EOC cell lines and nonmalignant control cells was detected. Cell proliferation, apoptosis and candidate target miRNA (miR-149, miR-183 and miR-194) expressions were detected in circ-PVT1 overexpression treated CAOV3 cells and circ-PVT1 knock-down treated SKOV3 cells. Furthermore, miR...
