Mesenchymal markers, such as vimentin, moesin, and receptor tyrosine kinase Axl, are highly expressed in TNBC basal B subtype of breast cancer cells (Additional file 2, [9, 36]), and vimentin and Axl proteins were expressed in a subset of human TNBC tumors from patients [36]. This evidence concerns the gene NTRK1 and breast carcinoma.
