CD8A and cancer: Consistent with the prognostic coefficient from the Cox model, the expression of PFKP-DT was positively correlated with the levels of cancer-killing immune cells such as CD8+ T cells, while the expression levels of CRNDE and LINC02984 were positively related to the infiltration levels of M2 macrophage, whose predominance contributed to the suppression of immunity (Figure 6(d) and Figure S7(D)) [31].
