Effect of ATP on cell viability and cell proliferation in normal and lung cancer cells. A: summarized data (means ± SE) showing cell viability of normal (left) and lung cancer cells (middle and right) treated with ATP (0 μM, 100 μM, 1 mM; n = 4 separated experiments, *P < 0.05 vs. Control). B: summarized data (means ± SE) showing cell proliferation of normal (left) and lung cancer cells (middle and right) treated with ATP (0 μM, 100 μM or 1 mM; n = 4 separated experiments, *P < 0.05 vs. Control).
