Correlation of FNBP1 expression with immune infiltration level in BRCA (breast invasive carcinoma), LUAD (lung adenocarcinoma), STAD (stomach adenocarcinoma). A FNBP1 expression was significantly negatively related to tumor purity and had significant positive correlations with the level of infiltrating B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells in BRCA (n = 1093). B FNBP1 expression was significantly negatively related to tumor purity and had significant positive correlations with the level of infiltrating B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells in LUAD (n = 515). C FNBP1 expression was negatively related to tumor purity and had significant positive correlations with the level of infiltrating B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells in STAD (n = 415)
