Fig. 4From: Functional analyses of ATM, ATR and Fanconi anemia proteins in lung carcinomaNo synergy was seen between gemcitabine and ATM kinase inhibitor. Exponentially dividing lung cancer cell lines were treated with increasing doses of gemcitabine and a fixed concentration of ATM kinase inhibitor KU55933 for 48Â h and MTT reagent was then added. Representative examples from at least 3 replicate experiments are shown (mean, SD of 4 replicates)Back to article page
