EGFR and lung carcinoma: To evaluate whether this observation was consistent across the genotypes of interest, we compared the expression of total and mutant EGFR and MET across a broader panel of lung cancer cell lines and xenografts, including EGFR-dependent models (H1975, H3255, PC9, and HCC827), EGFR/MET-codependent cells (HCC827GR6), and MET-dependent cells (EBC-1 and H1993) (Fig. 4A and fig.
