When searching for overrepresented motifs in these regions a number of predicted transcription factors were related to cancers and oxidative stress, like nuclear factor kappa beta (NFKB1 and 2), jun dimerization protein 2 (JDP2), myb proto-oncogene like 1 (MYBL1) and runt-related transcription factor 3 (RUNX3). This evidence concerns the gene NFKB1 and cancer.
