GZMK and neoplasm: For instance, CD8+ T cell markers (such as CD8A, CD3D, and GZMK, p < 0.0001), neutrophil markers (such as FCGR3B, SELL, and CCR7, p < 0.0001), natural killer cell markers (such as KIR3DL1, GNLY, and PRF1, p < 0.0001), tumor-associated macrophage (TAM) markers (such as CCL2, CD68, and IL10, p < 0.0001) and M2 macrophage markers (such as CD163, VSIG4, and MS4A4A, p < 0.0001) showed significant correlation with the expression of SUCNR1 (Figures 2A–J).
