Özet
Background: In breast cancers, calcium signaling is a main cause of proliferation and apoptosis of breast cancer cells. Although previous studies have implicated the transient receptor potential vanilloid 1 (TRPV1) cation channel, the synergistic inhibition effects of selenium (Se) and cisplatin in cancer and the suppression of ongoing apoptosis have not yet been investigated in MCF-7 breast cancer cells. This study investigates the anticancer properties of Se through TRPV1 channel activity in MCF-7 breast cancer cell line cultures when given alone or in combination with cisplatin. Materials: The MCF-7 cells were divided into four groups: the control group, the Se-treated group (200nM), the cisplatin-treated group (40M) and the Se+cisplatin-treated group. Results: The intracellular free calcium ion concentration and current densities increased with TRPV1 channel activator capsaicin (0.01mM), but they decreased with the TRPV1 blocker capsazepine (0.1mM), Se, cisplatin, and Se+cisplatin incubations. However, mitochondrial membrane depolarization, apoptosis, and the caspase 3, and caspase 9 values increased in the Se-treated group and the cisplatin-treated group, although Western blot (procaspase 3 and 9) results and the cell viability levels decreased with the Se and Se+cisplatin treatments. Apoptosis and caspase-3 were further increased with the Se+cisplatin treatment. Intracellular reactive oxygen species production increased with the cisplatin treatment, but not with the Se treatment. Conclusion: This study's results report, for the first time, that at a cellular level, Se and cisplatin interact on the same intracellular toxic cascade, and the combination of these two drugs can result in a remarkable anticancer effect through modulation of the TRPV1.
