EGFR and non-small cell lung carcinoma: We further examined the cytotoxic effect of FGFC1 on a normal lung epithelial cell line (BEAS-2B) and three NSCLC cell lines with different EGFR status, consisting of two NSCLC cell lines (A549 and H1299) with wild type EGFR and another erlotinib-resistant NSCLC cell line H1975 harboring EGFR double mutations (L858R/T790M).
