Figure Lengend Snippet: ATM inhibition in combination with IFN-γ alters glutathione metabolism in NSCLC Cells were treated with IFN-γ (1000 ng/mL) and/or KU-55933 (10 μM) for 24 h, and then the intracellular levels of GSH and GSSG were quantified. The results of total glutathione (A), GSH (B), GSSG (C), and GSH/GSSG ratio (D) are shown. * p < 0.05.
