Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are effective against non-small cell lung cancer (NSCLC) with EGFR-activating mutations. The mechanisms underlying EGFR-TKI resistance are not fully understood. This study aimed to analyze the effects of seven EGFR ligands on EGFR-TKI sensitivity in NSCLC cells and patients. Cells with EGFR E746-A750del mutation were treated with recombinant EGFR ligands, and analyzed for cell viability, proliferation, and apoptosis. shRNA knockdown of endogenous Epiregulin (EREG)
