Effect of RSF1 expression on NF-κB–dependent genes expression in ovarian cancercells. A and B, SKOV3 cells with a Tet-off RSF1 induction system were used. A, levels of RSF1, CFLAR, BCL2, BCL2 L1, and PTGS2 were analyzed by Western blotting with specific antibodies. Expression levels were normalized to β-actin. Data are representative of three different experiments. B, the mRNA expression of RSF1, CFLAR, BCL2, BCL2L1, and PTGS2 was analyzed by real-time RT-PCR. Data were normalized to GAPDH mRNA expression. C and D, OVCAR3 cells were transfected with specific RSF1 shRNA1, 2, or control shRNA. C, levels of RSF1, CFLAR, BCL2, BCL2 L1, and PTGS2 were analyzed by Western blotting with specific antibodies. Expression levels were normalized to β-actin. D, the mRNA expression of RSF1, CFLAR, BCL2, BCL2L1, and PTGS2 was analyzed by real-time RT-PCR. Data were normalized to GAPDH mRNA expression. Data are representative of three different experiments and are shown as the mean ± SD. *, P < 0.05 compared with the RSF1 no induction group or the control shRNA group.
