More significantly, the expression level of PDIA5 showed positive correlations with the T cells and macrophages-related immune pathways in BLCA, COAD, GBM, KIRC, KIRP, LGG, and rectum adenocarcinoma (READ), and negative correlations in CESC, LUSC, PRAD, and THCA. This evidence concerns the gene PDIA5 and reading.
