NFKB1 and ovarian cancer: Further co-immunoprecipitation assays identified increased RSF1 binding with NF-κB in RSF1 expression-induced SKOV3 ovarian cancer cells; an interaction between RSF1 and NF-κB was also observed in endogenous RSF1-overexpressing OVCAR3 cells and RSF1-overexpressing SKOV3TR and OVCAR3TR cells, which are paclitaxel-resistant ovarian cancer cells.
