HLA-DRB1 and neoplasm: Finally, differential expression of immune markers HLA-A, HLA-DRB1, KIR2DL3 and MAGEC1 was highlighted in Figure 1E. Slightly increased expression of HLA-DRB1 could be observed in VMM1 (p < 0.05), while overexpression of KIR2DL3 could be found in MNT-1 (~8-fold change) when compared to primary tumor cells.
