Therefore, in this study we identify the relative gene expression of IL6, CSF2, CCL5, VEGFA, and VEGFC and their receptors (GP130, GMRA, GMRB, CCR5, VEGFR2, NRP1, VEGFR3, and NRP2, Fig. 1), in multiple breast cancer subtypes (Basal, HER2+, Luminal A, and Luminal B) using high-throughput genomic data of primary tumors from the Cancer Genome Atlas (TCGA)14 and Molecular Taxonomy of Breast Cancer International Consortium METABRIC15. This evidence concerns the gene IL6 and breast cancer.
