UBE2S promotes Olaparib resistance via its enzymatic activity. A2780 and SKOV3 cells transfected with PCMV, PCMV-UBE2S (UBE2S), and PCMV-UBE2S-C95S (C95S) were treated with Olaparib (A2780, 15 μM; SKOV3, 30 μM) for 48 h. A The CCK8 assay was performed to detect cell viability. B The protein levels of PARP, cleaved caspase 3, and β-actin were detected by western blot. C and D Quantification of relative protein levels in (B). E Clonogenic assay was performed to determine the colony formation efficiency of A2780 and SKOV3 cells. F Quantification of the number of clones in (E). (Data are mean ± SEM, *p < 0.05, **p < 0.01, n = 3)
