Next, we tested whether human NSCLC lines, including H23 cells (Kras mutation in codon 246), H1299 cells, (mutant Kras in codon 61), and A549 cells (Kras mutation in codon 12), along with non-malignant human bronchial epithelial cells (BEAS-2B), express functional MerTK. The gene discussed is MERTK; the disease is non-small cell lung carcinoma.
