What is the role of VEGFR2?
VEGFR-2 is an important target of anti-tumor angiogenesis. VEGF secreted by tumor cells activates its receptor VEGFR-2, and they subsequently promote vascular growth and supply the oxygen and nutrition into the hypoxic areas of tumor tissues (Lugano et al., 2020).
What kind of receptor is Vegfr-2?
type V receptor tyrosine kinase
Vascular endothelial growth factor receptor 2 (VEGFR2) is a type V receptor tyrosine kinase mainly known to be expressed in vascular endothelial cells and encoded by the KDR gene.
What is the mechanism of action for bevacizumab?
Bevacizumab acts by selectively binding circulating VEGF, thereby inhibiting the binding of VEGF to its cell surface receptors. This inhibition leads to a reduction in microvascular growth of tumor blood vessels and thus limits the blood supply to tumor tissues.
What drugs are VEGF inhibitors?
The VEGF-kinase inhibitors utilized currently in clinical practice in the United States include bevacizumab, sorafenib, sunitinib, nilotinib, pazopanib, and dasatinib. Common features of these drugs/inhibitors are outlined in Table 1.
What is the VEGF pathway?
The VEGF (vascular endothelial growth factor) signaling pathway regulates vascular development in the embryo (vasculogenesis) and new blood vessel formation (angiogenesis).
What is the signaling cascade mechanism of VEGF?
​VEGF signaling pathway VEGF signaling is induced by the binding of VEGF ligands to their cognate membrane-bound receptors, which results in the activation of multiple downstream pathways. VEGF signaling cascade includes: the Ras/MAPK pathway, regulating cell proliferation and gene expression.
Where is VEGFR?
Within the blood compartment, VEGF is mostly concentrated in the platelets, although a significant portion was localised in leukocytes during cancer development. Large quantities of VEGF were reported in tumour and skeletal muscle, the latter of which suggested an intracellular VEGF source.
What is the molecular target of bevacizumab?
Bevacizumab, a recombinant humanised monoclonal antibody developed against VEGF, binds to soluble VEGF, preventing receptor binding and inhibiting endothelial cell proliferation and vessel formation.
What is the synonym for drug class Vegfr-2 inhibitor?
VEGFR-2 inhibitor, also known as kinase insert domain receptor(KDR) inhibitor, are tyrosine kinase receptor inhibitors that reduce angiogenesis or lymphangiogenesis, leading to anticancer activity.
