Preferred Label : VEGF Signaling Pathway;
Alternative definition : KEGG: There is now much evidence that VEGFR-2 is the major mediator of VEGF-driven
responses in endothelial cells and it is considered to be a crucial signal transducer
in both physiologic and pathologic angiogenesis. The binding of VEGF to VEGFR-2 leads
to a cascade of different signaling pathways, resulting in the up-regulation of genes
involved in mediating the proliferation and migration of endothelial cells and promoting
their survival and vascular permeability. For example, the binding of VEGF to VEGFR-2
leads to dimerization of the receptor, followed by intracellular activation of the
PLCgamma-PKC-Raf kinase-MEK-mitogen-activated protein kinase (MAPK) pathway and subsequent
initiation of DNA synthesis and cell growth, whereas activation of the phosphatidylinositol
3'-kinase (PI3K)-Akt pathway leads to increased endothelial-cell survival. Activation
of PI3K, FAK, and p38 MAPK is implicated in cell migration signaling.;
