Using total RNAs and proteins from SKOV3, OVCAR3, OV-90 , 3AO and SKOV3DDPovarian cancers cell lines, we show using real-time RT-PCR and immunoblotting that all ovarian cancer cell lines, except SKOV3 VO-90 and 3AO, express higher levels of bcl-2 mRNA and protein, respectively. The gene discussed is BCL2; the disease is cancer.
