Concerning macrophages (Figure 8B), TNFAIP6 gene expression levels were significantly (p < 0.05) correlated with macrophages in Basal, Her2, Luminal A, and Luminal B cancer patients; IFRD1 was positively correlated with macrophages in Her2 and Luminal B patients, and IFITM2 was only correlated with macrophages in Basal patients, whereas IFNGR1 gene expression levels were significantly (p < 0.05) positively correlated with macrophages in Basal, Her2, Luminal A, and Luminal B cancer patients. This evidence concerns the gene ERBB2 and cancer.
