PDGFRB and triple-negative breast carcinoma: We also described the role of platelet-derived growth factor receptors beta (PDGFRβ) in mediating the endothelial differentiation of triple negative breast carcinoma cells [72] and we recently described the involvement of PDGFRβ in the regulation of the CDCP1 [73], a transmembrane protein which is overexpressed in TNBCs and is involved in tumor progression [74].
