TGFB1 and breast cancer: In order to assess whether our results obtained in preclinical mouse models also have clinical relevance in humans, we evaluated different human public transcriptomic databases (The Cancer Genome Atlas [TCGA] and Molecular Taxonomy of Breast Cancer International Consortium [METABRIC]) to assess the prognostic effect of TGF-β (gene expression level) and TGF-β signaling (TGF-β1–associated metagene) (17) on prognosis, as well as their links to the immune response in human TNBC.
