The results showed that the expression of DMRT3 correlated negatively with the expression of the immune checkpoint genes in 18 tumor types, including ACC, BRCA, CHOL, COAD, DLBC, GBM, HNSC, KICH, KIRP, LIHC, LUAD, OV, PAAD, PCPG, PRAD, READ, SARC, and SKCM (Figure 8). The gene discussed is DMRT3; the disease is glioblastoma.
