LINC01503 is a sponge for miR-766-5p. A The potential binding sites of miR-766-5p on LINC01503 was predicted by DIANA website. B and C Levels of miR-766-5p and LINC01503 were measured by RT-qPCR in OVCAR-3/CBP and CAOV-3/CBP cells. D Luciferase activities of wild-type or mutant LINC01503 in CBP-resistant OCa cells transfected with NC mimics or miR-766-5p mimics were detected by luciferase reporter assay. E The expression levels of miR-766-5p in CBP-resistant and sensitive OCa cell lines were measured by RT-qPCR. F The expression levels of miR-766-5p in OVCAR-3/CBP and CAOV-3/CBP cells transfected with Vector, LINC01503, si-NC, and si-LINC01503 were determined by RT-qPCR. (n = 3; **P < 0.01)
