Spearman’s correlation analysis revealed that PLAU, MMP14, TWIST1, and TAP2 was positively correlated with the expression level of most tumor-infiltrating lymphocytes, while TPX2, SERPINB5, MPZL2, and S100A14 was negatively correlated with monocytes, plasmacytoid dendritic cells, type 1 T helper cells, regulatory T cells, and eosinophils. The gene discussed is PLAU; the disease is neoplasm.
