FGFR1 and lung carcinoma: By using DNA- and RNA-directed lung-cancer sequencing panels to compare the three FGFR1 inhibition-resistant single clones with their sensitive parental control cell line (NCI-H1581) we could exclude several known mechanisms of AKT activation, e.g., AKT, RAS, PTEN, PIK3CA or FGFR1 gatekeeper mutations, overexpression of AKT, FGFR1 or activation of MET (Fig. 3e and S3d, e).
