Clonogenic survival of SiHa cervical carcinoma cells in the plateau phase, irradiated under oxic conditions. Data from three independent experiments, each performed in triplicate (mean ± SEM). MG-132 was added 30 minutes before the start of the first cycle of hypoxia and remained in the medium until cells were irradiated. Control cells (○), three cycles of hypoxia/reoxygenation (◊), MG-132 at 50 µM (△), three cycles of hypoxia/reoxygenation, and preincubation with MG-132 at 50 µM (▽).
