Circ-BNC2 inhibits the progression of OC cells by sponging miR-223-3p. A SKOV3 were transfected with negative control (NC), circ-BNC2 overexpression plasmid (Oe-circ), Oe-circ + miR-223-3p mimics, and qRT-PCR was applied to detect the expression of miR-223-3p in SKOV3 cells after transfection. B CCK-8 assay used to detect the proliferation of SKOV3 cells after transfection. C Transwell assay was used to detect the migration and invasion of SKOV3 cells after transfection. Scale bar: 500 μm. D Cell cycle assays used to detect the cell cycle distribution of SKOV3 cells after transfection. *P < 0.05, **P < 0.01, and ***P < 0.001
