From: ATM activation accompanies histone H2AX phosphorylation in A549 cells upon exposure to tobacco smoke

Figure 3

Induction of ATM activation in A549 cells by CS as revealed by Western blotting. The cells were exposed to 5, 10, 15 or 20 min of IM16 smoke (CS) and harvested at 30 min post-exposure. The extent of ATM activation (ATM-S1981P) was determined by Western blotting and compared with the respective samples of the mock treated cells (M) and with expression of ATM detected by antibody that was not phospho-specific.
