We also compared the status of E2A-PBX1 fusion transcripts and mutation status of K-ras, p53 and EGFR in the NSCLC cell lines used in our study (mutation information was obtained from The COSMIC (Catalogue of Somatic Mutations in Cancer) database and website[25]) (Table 3 and Table 4). This evidence concerns the gene KRAS and non-small cell lung carcinoma.
