To study radiosensitizing effect and apoptosis induction of wortmannin on human glioma cells, colony formation assay, flow cytometry, laser confocal microscope were used to investigate the inhibition effect on colony formation, apoptosis and cell cycle procession. Experiment results suggested that wortmannin could inhibit colony formation in SHG-44 cells, and the combination of wortmannin with ,60,Co γ-irradiation showed a synergistic action. Wortmannin could also induce G,1, arrest, apoptosis, and morphologyical changes such as karyopyknosis, nuclear-fragmentation and apoptotic body were observed. The above results revealed that wortmannin can sensitize SHG-44 cells to gama radiation, which might be related with G,1, arrest and apoptosis pathway.
