IGF1R and non-small cell lung carcinoma: We confirmed the expression level of FAK, p-FAK, IGF-IR, and p-IGF-IR in cell lines without drug exposure using ten NSCLC cell lines (EGFR-mutant cell lines, PC-9, HCC827, NCI-H3255, HCC4006, NCI-H1975, NCI-H820 and RPC-9; EGFR wild-type cell lines, NCI-H1819, NCI-H1299 and A549).
