In benign mixed tumor cells, the level of fold change in MAGE-B1, -B4, -B5, and -B10 mRNA expression in cells treated with 5-aza-CdR was higher than in the control group, while the level of fold change in MAGE-B1, -B4, -B5, and -B10 mRNA expression in cells treated with TSA was lower than in the control group. This evidence concerns the gene MAGEB1 and neoplasm.
