We assayed bisulfite extracted DNA from 76 HNSCC tumor tissues and 17 normal mucosa samples for MAGEB2, KBGP/XK, DEAD/DDX43 which were found according to the preliminary BSS to be the most highly significant and showed high upfold expression values in AZA treated OKF6-T1 cell line (Figure 3, Table S6). This evidence concerns the gene MAGEB2 and head and neck squamous cell carcinoma.
