In KIRC, significant correlations were observed between PTP4A3 expression and tumor purity (R=-0.231, P=5.2E-07), B cells (R=-0.094, P=4.41E-02), CD8+ T cells (R=0.116, P=1.53E-02), CD4+ T cells (R=0.351, P=9.27E-15) and neutrophils (R=0.145, P=1.92E-03), but not with macrophages (R=0.007, P=1.39E-01) or dendritic cells (R=0.072, P=1.26E-01). The gene discussed is CD4; the disease is neoplasm.
