Knockdown of circUBAP2 hampered proliferation and invasion of OS cells. a The expression of circUBAP2 in OS cells transfected with si-circUBAP2, as well as matched controls, was assessed by qRT-PCR. b Cell proliferation at different time points was evaluated by CCK-8 assay. c, d Transwell assay was utilized to check cell invasion, and corresponding invaded cells were calculated. e, f The protein levels of E-cadherin and Vimentin in Control and transfected OS cells were determined by western blot. *P < 0.05
