Recombinant human VEGF-121 stimulates proliferation of HUVEC in a dose-dependent manner (dark purple squares). Proliferation induced by recombinant human VEGF-121 (15 ng/mL) is neutralized (purple circles) by increasing concentrations of anti-VEGF-121 (clone A15136B) antibody. The ND50 is typically 25 - 100 ng/mL.

VEGF was initially identified in conditioned medium from bovine pituitary follicular cells. VEGF-A belongs to the VEGF family, which has the following members: VEGF-A, VEGF-B, VEGF-C, VEGF-D, and PlGF (placental growth factor). In addition, viral VEGF homologs (collectively called VEGF-E) and snake venom VEGFs such as T.f. (Trimeresurus flavoviridis) and svVEGF (called VEGF-F) have been described. VEGFA is alternatively spliced to generate variants with different number of amino acids such as VEGF-121, VEGF-145, VEGF-165, and VEGF-189. While VEGF-121 is freely diffusible and does not bind to heparin sulphate, VEGF-165 and VEGF-189 bind to heparin sulfate, resulting in retention on the cell surface or in the extracellular matrix. VEGF-A is highly expressed in solid tumors generated in breast, lung, renal, colorectal and liver tissues. VEGF has strong vascular permeability activity and significantly contributes to the formation of ascites tumors. VEGF can act as a direct proinflammatory mediator during the pathogenesis of rheumatoid arthritis (RA) and protect rheumatoid synoviocytes from apoptosis, which contributes to synovial hyperplasia. VEGF is expressed in synovial macrophages and synovial fibroblasts in RA patients. Also, VEGF is associated with age-related macular degeneration (AMD). AMD is due to neovascularization that originates from endothelial cells in the choroid that grow into neurosensory retina as choroidal neovascularization (CNV).

Antigen Details
- Structure
- Homodimer.
- Function
- VEGFA is a key player in vasculogenesis, the formation of blood vessels from progenitor cells, as well as angiogenesis. The expression of the VEGFA gene is upregulated via hypoxia, estrogen, and NF-κB pathways. In addition VEGF is upregulated by PDGF-BB, P1GF, TGFβ1, IGF1, FGFs, HGF, TNFα, and IL-1. VEGFA induces proliferation and cell migration in endothelial cells and plays important roles during wound healing. Also, VEGF regulates hematopoietic stem cell survival.
- Interaction
- VEGFA interacts with vascular endothelial cells and monocytes/macrophages, which express VEGFR1. This interaction induces proliferation of endothelial cells and stimulates migration of monocytes/macrophages.
- Ligand/Receptor
- VEGFR1 (Flt-1) and VEGFR2 (KDR/Flk-1).
- Biology Area
- Angiogenesis, Cancer Biomarkers, Cell Biology, Cell Proliferation and Viability
