Statistical analysis performed on data obtained from all (n = 14) investigated melanoma cells showed significant differences in levels of NY-ESO-1 (p < 0.0001) and MAGE-A1 (p < 0.05) expression detected after treatment with guadecitabine and DAC, but not with AZA, vs. untreated cells (Supplementary Tables 3, 5). The gene discussed is MAGEA1; the disease is melanoma.
