ABSTRACT
Testicular cancer is the most common cancer among young men of reproductive age. Bleomycin is a frequently used drug for the treatment of several malignancies and is part of the chemotherapy protocols in testicular cancer. Bleomycin causes an increase in oxidative stress which has been shown to induce apoptosis in cancer cells. Curcumin (diferuloylmethane), an active component of the spice turmeric, has attracted interest because of its anti-inflammatory and chemopreventive activities. However, no study has been carried out so far to elucidate its interaction with bleomycin in testicular cancer cells. In this study, we investigated the effects of curcumin and bleomycin on apoptosis signalling pathways and compared the effects of bleomycin with H2O2 which directly produces reactive oxygen species. We measured apoptosis markers such as caspase-3, caspase-8, and caspase-9 activities and Bcl-2, Bax, and Cyt-c levels in NCCIT cells incubated with curcumin (5 ìM), bleomycin (120 ìg/ml), bleomycin + curcumin, H2O2 (35 ìM), and H2O2 + curcumin for 72 h. Curcumin, bleomycin, and H2O2 caused apoptosis indicated as increases in caspase-3, caspase-8, and caspase-9 activities and Bax and cytoplasmic Cyt-c levels and a decrease in Bcl-2 level. Concurrent use of curcumin with bleomycin decreased caspase activities and Bax and Cyt-c levels compared to their separate effects in NCCIT cells. Our findings suggest that concurrent use of curcumin during chemotherapy in testis cancer should be avoided due to the inhibitory effect of curcumin on bleomycin-induced apoptosis (AU)
