Effect of KU55933 formulations and radiation on phosphorylation of ATM, Akt and H2AX. H460 cells were pretreated with 10 μM KU or NP KU (containing 10 μM KU) for 3 h and subsequently irradiated (1 Gy). (A) Cell lysates were collected at indicated time points for western blot. The western blot band intensity was quantified after normalized to β-actin based on three independent experiments. (B) Cells were fixed at indicated time points for immunofluorescence of γH2AX. (C) Average numbers of γH2AX foci per cell were presented.
