Our results revealed that the expression of DLD was positively correlated with B-cell infiltration in PAAD, PCPG, and PRAD (Figure 8A); CD4+ T-cell infiltration in HNSC-HPV- (Figure 8B); CD8+ T-cell infiltration in UVM (Figure 8C); cancer-associated fibroblast infiltration in HNSC (Figure 8D); monocyte infiltration in KIRC (Figure 8E); mast cell infiltration in BRCA-LumA and KIRP (Figure 8F); and neutrophil infiltration in BRCA, KIRC, LIHC, LUAD, PRAD, and STAD (Figure 8H). Here, TMEM43 is linked to invasive breast carcinoma.
