KDR and cancer: Aberrant expression and/or activation of oncogenic signaling by kinases such as the Src and Abl tyrosine kinases, and receptor tyrosine kinases (RTKs) MET, Vascular endothelial growth factor receptor (VEGFR), Fibroblast growth factor receptor (FGFR), Insulin-like growth factor receptor 1 (IGF-1R), as well as members of the epidermal growth factor receptor (EGFR) family, have been well documented to play pivotal roles in cancer development, progression, metastasis, and often function as significant drivers of development of therapy resistance in many cancers including TNBCs [15].
