Effects of COX-2 inhibition on NSCLC cell growth. Lung cancer cells from three NSCLC cell lines were treated with various concentrations (0, 0.02, 0.2, 2 and 20 μM) of NS-398 for 48 h. Cell numbers were counted by direct cell counting using Trypan Blue stain and the Hemocytometer. Each bar is the mean ± SEM of three determinations from two independent experiments.
