CD274 and cancer: We observed that the expression of PD-L1 had significantly positive associations with the expression of GLNM regulators in 23 types of cancers, including ACC, BLCA, BRCA, COAD, DLBC, ESCA, GBM, KICH, KIRC, KIRP, LAML, LGG, LIHC, LUSC, MESO, OV, PAAD, PCPG, PRAD, SARC, THCA, UCEC, and UVM (Figure 7); however, there were no significant associations between PD-L1 expression and the expression of GLNM regulators in the remaining ten cancer types (Figure S2).
