The results revealed that PKNOX1 was negatively correlated with monocytes in UVM, resting mast cells, regulatory T cells in TCGT and KIRC, and memory B cells in READ, and positively correlated with M1 macrophages in DLBC and UVM, M2 macrophages in TGCT, regulatory T cells in CHOL, and CD8 T cells in UVM (Figures 7B–K). This evidence concerns the gene CD8A and reading.
