Relative viability of H1299 (A), H1299 AXL KO (D), PC9 (F), and PC9 AXL KO (I) cells upon 72h treatment with increasing concentrations of the indicated drugs as measured by CellTiterGlo. Data are represented as mean ± SE and is the average of two independent experiments. Colony formation assay of H1299 (B), H1299 AXL KO (E), PC9 (G), and PC9 AXL KO (J) cells post treatment with the indicated doses of RXDX-106, Bemcentinib (Bem), Cabozantinib (Cabo) or Erlotinib (Erlo) for 9 days. Immunoblot analyses showing alterations in downstream signaling in H1299 (C), PC9 (H), and PC9 AXL KO (K) cells when exposed to the indicated concentrations of the different drugs for 1h. Shown is representative of three independent experiments.
