Fig 5. Radiosensitizing effect of DIO on A549/IR cells is dependent on Akt activation.
A549/IR cells were treated by 10 μM DIO, 20 μM LY294002 and 10 μM MK-2206 for 24 h and irradiated at 6 Gy for 1 h. Then, the protein expression levels were analyzed by western blot with the indicated antibodies. β-actin used as an internal normalization control.
