Correlation between induction of expression of ATM-A1981P and γH2AX in A549 cells following exposure to CS. Cells were exposed to CS from cigarettes with different tobacco and filter combinations. Each sample was processed in parallel to measure expression of ATM-S1981P and γH2AX and the data are presented as the regression plot with 95% confidence limits. The correlation coefficient R = 0.89.
