Similarly, in KIRP, PTP4A3 expression was correlated with B cells (R=0.222, P=3.39E-04), CD8+ T cells (R=0.148, P=1.78E-02), CD4+ T cells (R=0.16, P=1.02E-02), neutrophils (R=0.200, P=1.22E-03) and dendritic cells (R=0.247, P=6.63E-05), but not with tumor purity (R=0.015, P=8.06E-01) or macrophages (R=-0.009, P=8.83E-01) (Figure 5A). This evidence concerns the gene CD8A and neoplasm.
