In NSCLC, EGFR transactivation is also mediated by ROS-dependent NADPH oxidase activity/c-Src, which results in the downstream activation of the PI3K/AKT/NF-κB pathway and cyclooxygenase-2, which are molecular predictors of the overall survival of patients with NSCLC [92]. This evidence concerns the gene NFKB1 and non-small cell lung carcinoma.
