Fig. 2: USP43 regulates OC cell proliferation and migration.

A A2780 and TOV-21G cells were transiently transfected with siRNA specific for USP43 (si1 or si2) or control siRNA (NC). B CCK-8 assay was employed to study the cell proliferation after silencing USP43 in A2780 and TOV-21G cells (n = 3). C Colony-forming assay was employed to investigate the proliferation ability of A2780 and TOV-21G cells after USP43 silencing (n = 3). D Cell migration assay was performed in USP43-silenced cells and negative control cells (n = 3). E Overexpression of USP43 was verified using western blotting. F, G CCK-8 and colony-forming assays showed that USP43 overexpression enhanced proliferation and colony-forming ability of A2780 and TOV-21G cells (n = 3). H Transwell assay showed that USP43 overexpression induced the migration of A2780 and TOV-21G cells (n = 3). I, J Western blotting confirmed that USP43 influences the expression of migratory proteins such as vimentin, E-cadherin, and N-cadherin. Data are presented as mean ± SD.
