CD8+ T cell’s biomarkers (CD8A and CD8B), B cell’s biomarkers (CD19 and CD79A), Monocyte's biomarkers (CD115 and CD86), TAM's biomarkers (CCL2, CD68 and IL10), M1 macrophage’s biomarkers (COX2, NOS2, and IRF5), M2 macrophage’s biomarkers (CD163, MS4A4A, and VSIG4), neutrophil’s biomarkers (CCR7, ITGAM and CEACAM8), and dendritic cells’ biomarkers (CD1C, NRP1, ITGAX, HLA-DPA1, HLA-DPB1, HLA-DQB1, and HLA-DRA) shows high correlation with FNBP1 in BRCA, LUAD and STAD. This evidence concerns the gene ITGAX and gastric adenocarcinoma.
