To evaluate the effect of BNIP3 in ovarian cancer during cisplatin treatment and whether it could work as a prognostic factor, we measured the level of BNIP3 before and after exposure to cisplatin in ovarian cancer cells, evaluated the relation of BNIP3 level to cisplatin cytotoxicity and cellular apoptosis, and examined the correlation between BNIP3 and clinical outcomes. The gene discussed is BNIP3; the disease is ovarian carcinoma.
