Rapamycin suppresses ROS-dependent apoptosis caused by selenomethionine in A549 lung carcinoma cells

Purpose Although selenium compounds possess chemotherapeutic features by inducing apoptosis in cancer cells with trivial side effects on normal cells, the mechanisms underlying its anti-cancer activity are insufficiently understood at the present. In this study, we investigated the effects of rapamycin on apoptosis induced by seleno-L-methionine (SeMet) or selenite in A549 cells.
