ATM and B-cell chronic lymphocytic leukemia: We also plotted cell death in CLL samples treated with 10-μM AZD1208 for 24 h according to molecular marker status: zeta-chain-associated protein kinase 70 (41samples; negative = 21, positive = 20), p53 (del17p, 31 samples; negative = 14, positive = 17), and ATM (del11q, 29 samples; negative = 7, positive = 22) status.
