The CCK8, colony-forming, EdU and transwell assays revealed that the enhanced proliferation and invasion of SKOV3 and A2780 cells induced by overexpression of LINC00152 could be further boosted by co-overexpression of the wild-type BCL6 but not the mutant BCL6Ser333/Ser343; meanwhile, overexpression of exogenous BCL6 Ser333/Ser343 failed to rescue the abolished proliferation and invasion caused by knockdown of endogenous BCL6 in LINC00152-overexpressing tumor cells (P < 0.05, Figures 8A–D). Here, BCL6 is linked to neoplasm.
