AIM: To explore if a natural isothiocyanate, sulforaphene (SFE), sensitizes ovarian cancer cells to the chemotherapy drug cisplatin (CDDP).
MATERIALS AND METHODS: We studied reactive oxygen species (ROS), mitochondrial membrane depolarization and cell-cycle distribution in two ovarian cancer cell lines SKOV3 and SNU 8 treated with SFE and cisplatin. We further analyzed the expression of caspases 3, 8, and 9, Phosphoinositide 3-kinase (PI3K) and Phosphatase and tensin homolog (PTEN) by western blotting.
RESULTS: SFE sensitized cells to cisplatin by enhancing ROS and mitochondrial membrane depolarization that released cytochrome c and activated caspase 9 and caspase 3 in the mitochondrial pathway. It also inhibited extrinsic pathway protein caspase 8, growth-related protein PI3K and further activated PTEN in combination with cisplatin.
CONCLUSION: SFE synergistically inhibited proliferation and induced apoptosis of SKOV3 and SNU8 cells in combination with cisplatin by activating multiple apoptotic pathways. Therefore, we suggest sulforaphene as a chemo-enhancing adjuvant to improve the efficacy of cisplatin in ovarian cancer treatment.
