Prolonged upregulation of the expression of HLA class I antigens and costimulatory molecules on melanoma cells treated with 5-aza-2'-deoxycytidine (5-AZA-CdR).

Abstract excerpt

The immunogenic potential of melanoma cells and their recognition by the host's cytotoxic cells depends on the presence and on the level of expression of human leukocyte antigen (HLA) class I antigens, costimulatory molecules and melanoma-associated antigens (MAA), on neoplastic cells. In this study, we demonstrate that the DNA hypomethylating agent 5-aza-2'-deoxycytidine (5-AZA-CdR), significantly (p < 0.05)...
