As Figure 7A shows, SNRPA1 expression was significantly positively correlated with chemokine, chemokine receptors, MHC, and immuno-inhibitor and immuno-stimulator genes in multiple cancer types including UVM, LIHC, PAAD, KICH, OV, KIPAN, and KIRC, but negatively related to those genes in TCGT, THYM, DLBC, STAD, STES, LUAD, LUSC, ESCA, CESC, and HNSC (Figure 7A). Here, HLA-C is linked to cancer.
