Epigenetic modifying drugs such as azacitidine and vorinostat may boost the anti‐leukaemia T cell immune response by upregualting Cancer‐Testis Antigens expression.6, 7 First we showed that treatment of AML cell lines with Azacitidine and Vorinostat can upregulate MAGE, LAGE, RAGE, TRAG3, and SSX2 CTAGs on AML tumour cell lines (Supporting Information Fig. S1a). The gene discussed is SSX2; the disease is acute myeloid leukemia.
