EGFR and non-small cell lung carcinoma: As such, neither the PI3K inhibitors LY294002 and Wortmannin nor a specific AKT inhibitor had any effect on BIM induction in NSCLC cells expressing mutant EGFR. This finding indicates that the PI3K–AKT–FOXO3 pathway is not critical for BIM induction after gefitinib treatment in these cells.
