Inhibition of miR-942-5p reverses the effect of circ_0015756 knockdown on OC cell progression. a The knockdown efficiency of miR-942-5p was measured by qRT-PCR. b–i OV90 and SKOV3 cells were introduced with si-NC, si-circ_0015756, si-circ_0015756+ anti-miR-NC or si-circ_0015756+ anti-miR-942-5p, respectively. b–e Cell proliferation capacity and proliferation-related protein levels were evaluated by CCK-8 assay, colony formation assay and Western blot assay. Cell apoptosis f, migration and invasion g, h and metastasis-related protein levels i were detected by flow cytometry, transwell assay and Western blot assay. *P < 0.05
