These differences, in turn, deregulate the expression of important and common target genes, many of them with a clear oncogenic and regulatory role in this disease, highlighting five genes (FOXF2, KLF13, MICA, TCEAL1, TGFBR2) that have also a potential prognostic value in NSCLC patients. This evidence concerns the gene TCEAL1 and non-small cell lung carcinoma.
