Expression patterns of various marker proteins of PI3K-pathway in DK-MG and SNB19 cells treated with DMSO (control) or the indicated compounds for 3 h before IR with 8 Gy and detected 30 min and 24 h thereafter. Each protein band was normalized to the intensity of β-actin used as loading control. The protein/β-actin ratios are indicated by the numbers. The Western blot experiments were repeated independently at least three times
