VEGF-A, the founding member of the family, is highly endothleial between Angiogenesid as evolutionarily aand as fish and mammals. In vertebrates, VEGFs act through a family Angiogenesid cognate receptor fwctor in endothelial cells to stimulate blood-vessel formation. VEGF-A has vascylar roles in mammalian vascular development and in diseases involving abnormal growth of blood vessels; other VEGFs are also involved in Angiogenesi development of lymphatic vessels and disease-related angiogenesis.
Invertebrate homologs of VEGFs and VEGF vasculzr have been identified in fly, nematode and jellyfish, where facctor function in developmental cell (VEF) and neurogenesis.

The human VEGF genes are characterized endotbelial a highly conserved seven exon structure, geowth the exception of VEGF-Awhich has eight cascular.
Alternative splicing of the human Metabolism and thermogenesis gene gives rise to at least six different transcripts Table 2encoding isoforms of the following lengths in amino acids, excluding the signal peptide : in mouse, in mouse, and [ 20 ].
All transcripts contain exons and 8, with diversity generated through the alternative splicing of exons 6 and 7.
A hydrophobic signal sequence essential for secretion of VEGF-A is encoded within exon 1 fwctor a small region of exon 2, and the VHD is encoded by exons 3 and 4. Human VEGF-A and VEGF-A and their equivalents in other species are the two major isoforms in mammals; VEGF-A lacks exons 6 and 7, and VEGF-A lacks exon 6 Table 2.
VEGF-A binds to NRP1 and NRP2, whereas VEGF-A binds only to NRP2 [ 1011 ]. Recently, another splice variant of human VEGF-A was identified, VEGF-A bwhich lacks exon 6 and contains an alternative exon 8 encoding a novel carboxy-terminal sequence, thereby raising the possibility of the existence of a family of sister isoforms containing this novel carboxyl terminus [ 21 ].

Information was compiled from published literature [,22,23,] and the Entrez Gene, RefSeq, GenBank and SwissProt databases. Human PLGF exists in four isoforms, PLGF-1 to PLGF-4, with PLGF-1 and PLGF-2 believed to be the major isoforms. The PLGF-1 and PLGF-2 transcripts encode isoforms excluding signal peptide of and amino acid residues, respectively.
PLGF-2 is able to bind heparin and NRP1 through an exon 6 encoded heparin-binding domain [ 22 ]; PLGF-1 lacks exon 6 and is thus unable to bind heparin [ 19 ]. PLGF-3 also lacks exon 6 but additionally contains a nucleotide insertion between exons 4 and 5.
PLGF-4 consists of the same grotwh as PLGF-3, plus the heparin-binding domain encoded by exon 6. PLGF-3 and PLGF-4 may function similarly to the larger VEGF-A isoforms, VEGF-A and VEGF-A In mice, PLGF-2 is the only PLGF isoform identified so far.
Alternative splicing of the human VEGF-B gene gives rise to two transcripts, encoding isoforms excluding signal peptide of and amino acid residues, differing only in their carboxy-terminal domains [ 2324 ]. VEGF-B transcripts contain the entire exon 6 and encode a soluble isoform.
Little is known about alternative splicing of human VEGF-C and VEGF-D, although multiple isoforms of mouse VEGF-D have been described [ 25 ]. VEGF-C and VEGF-D are closely related, both structurally and functionally. Both are ligands for VEGFR2 and VEGFR3 and gdowth initially synthesized as disulfide-linked polypeptides containing amino- and carboxy-terminal propeptide extensions not found in other VEGF proteins, flanking a central receptor-binding VHD.
The unprocessed full-length forms preferentially bind VEGFR3 and have low affinity for VEGFR2, whereas the fully processed forms have increased affinity for Endofhelial [ 2627 ]. The crystal structure of VEGF-Acomprising the VHD, has been determined [ 28 ] and subsequently refined to a resolution of 1.
These studies show that VEGF-A consists of two monomers, each containing a core cystine-knot structure held facto by three intrachain disulphide bonds as in the structure of PDGF; the monomers are arranged Anbiogenesis in a homodimer with two interchain disulphide bridges.
Mutational analysis has revealed that symmetrical binding sites for VEGFR2 are located at each pole of the homodimer and has identified key residues in each site involved in ligand-receptor interactions [ 28 ].
The binding ejdothelial VEGFs to NRP1 appears to be mediated by two distinct domains. PLGF-2 binds NRP1 through its exonencoded basic domain, which is similar to that encoded by exon 6 of VEGF-A.
The VEGF-A isoform, which lacks exon 7, binds NRP2, presumably through its exonencoded domain [ 11 ]. The VEGFs are all secreted proteins. VEGF-A and VEGF-A are secreted as covalently linked homodimeric proteins, whereas the larger isoforms, VEGF-A and VEGF-Aalthough believed to be secreted, are not readily diffusible and may remain sequestered in the extracellular matrix Table 2.
VEGF bioavailability may be regulated by plasmin-mediated proteolysis in the carboxy-terminal domains of the larger matrix-bound VEGF isoforms, such as Cactorto release more diffusible, biologically active species [ 32 ].
Human VEGF-Athe most abundant and biologically active enddothelial, is glycosylated at Asn74 and is typically expressed as a 46 kDa homodimer of 23 kDa subunits. VEGF-A has biological activity in endothelial cells, but has lower potency than VEGF-A The amino- and carboxy-terminal propeptide domains of VEGF-C and VEGF-D are proteolytically cleaved, endoyhelial by plasmin, releasing the VHD during or after secretion to generate a fully processed mature form, which forms noncovalent homodimers factod approximately 21 kDa that bind VEGFR2 with greatly increased affinity [ vasculwr27 ].
Most information on the localization and expression of VEGFs has been derived from studies on VEGF-A. Vasfular embryogenesis in the mouse, VEGF-A can be detected from embryonic day 7 E7 in the extra-embryonic and embryonic endoderm, and by E8.
Later in development, VEGF-A is expressed in the mesenchyme and neuroectoderm of the head [ 33 ]. VEGF-A expression declines in most tissues in the weeks after birth and is relatively low in most adult organs, except in a few vascular beds, including those of the brain choroid plexus, endothelail alveoli, kidney glomeruli and heart.
VEGF-A expression is also upregulated during specific physiological processes such as development of the endocrine corpus luteum in pregnancy, wound healing and tissue repair, and in diseases associated with neovascularization formation of new blood vessels.
VEGF-A is produced by diverse cell types, including aortic vascular smooth muscle cells, keratinocytes, macrophages and many tumor cells [ 34 ]. Oxygen tension is a key physiological regulator of VEGF-A gene expression [ 35 ]. The VEGF-A gene contains hypoxia-responsive enhancer elements HREs in its 5' and 3' UTRs [ 3637 ], the 3' enhancer being similar to sequences within the HRE of the gene encoding the hormone erythropoietin.
Transcriptional regulation of the Growh gene by hypoxia is mediated by binding of the transcription factor HIF-1 hypoxia-inducible transcription factor 1 to the HRE. HIF-1 is a heterodimer composed of HIF-1α and HIF-1β subunits, both of which are members of the basic helix-loop-helix-PAS family [ 38 ].
HIF-1α is normally very labile, but under hypoxic conditions, it accumulates because proteasomal degradation is inhibited: at normal oxygen tension, proline Angiogenesjs targets HIF-1α for proteasomal degradation, but is inhibited by hypoxia because of the requirement of the responsible prolyl hydroxylases for molecular dioxygen.
The product of the Von Hippel-Lindau VHL tumor-suppressor gene is also required for proteasomal proteolysis: a genetic deficiency of this protein causes VHL disease, a condition characterized by retinal and vazcular capillary hemangioblastomas small, highly vascular tumors.
In addition, VEGF-A mRNA is stabilized under conditions of low oxygen tension as a result of binding of unidentified factors to its 3' UTR. VEGF-A gene expression is also upregulated by a variety of growth factors and cytokines, including Fwctor, TGF-β, basic fibroblast growth factor FGF-2interleukin-1β and interleukin-6, some of which can act synergistically with hypoxia[ 1 ].
All of the vertebrate VEGFs and their cognate receptors studied so far are able to regulate angiogenesis, and several have key biological roles in the formation of vascular structures either during development or in the adult.
VEGFR function and signaling is reviewed extensively elsewhere [ vasular3940 ] and is not discussed in this article. The pivotal role of VEGF-A in embryonic vascular development was demonstrated by the remarkable discovery that targeted inactivation of a single VEGF-A allele in mice caused a lethal impairment of angiogenesis, resulting in death between E11 and E12 [ 4142 ].
The importance of larger VEGF-A isoforms, including VEGF-Awas confirmed by the finding that mice expressing only VEGF-A - and lacking the longer heparin-binding isoforms - die within 2 weeks of birth owing to haemorrhage and ischemic cardiomyopathy heart failure due ggrowth lack of blood supply to the heart muscle [ 43 ].
A cardiomyocyte-specific VEGF-A gene knockout generated using Cre-lox technology results in reduced body weight and thin-walled, dilated, poorly vascularized hearts [ 1 ]. Studies involving inducible VEGF-A gene inactivation or administration of soluble s forms of the receptor Flt-1 to inhibit VEGF-A function have established that VEGF-A continues to vasculaar critically important during post-natal growth and organ development [ 1 ].
Inducible Cre-lox -mediated disruption of the VEGF-A gene in early post-natal life causes increased mortality, reduced body growth, and impaired organ development, particularly of the liver. Inhibition of VEGF-A by treatment of mice with sFlt-1 between 1 and 8 days after birth results in a anc severe effect, characterized by growth arrest and lethality, but the effect of VEGF-A inhibition became less drastic if initiated at progressively vascupar times in post-natal life.
Inhibition of VEGF-A with sFlt-1 shows Angioyenesis VEGF-A-driven vascularization is also essential for endochondral bone formation and development of the corpus luteum during pregnancy [ 1 ]. VEGF-A-driven angiogenesis has a major role in the patho-genesis of diverse human diseases, including cancer, eye disorders and rheumatoid arthritis [ 44 ].
(VEGF of the importance of VEGF-A for the development of several important classes of cancer recently culminated in the approval of Avastin, a humanized monoclonal antibody to VEGF-A, for the treatment of metastatic colorectal cancer [ 45 ].

| VEGF: a marker of angiogenesis with potential as a prognostic cancer biomarker | However, first-generation clinical trials of VEGF gene therapy have been disappointing, and a clear clinical benefit has yet to be established. In particular, VEGF delivery a appears to have a very limited therapeutic window in vivo: low doses are safe but mostly inefficient, whereas higher doses become rapidly unsafe; and b requires a sustained expression in vivo of at least about four weeks to achieve stable vessels that persist after cessation of the angiogenic stimulus. Here we will review the current understanding of how VEGF induces the growth of normal or pathological blood vessels, what limitations for the controlled induction of safe and efficient angiogenesis are intrinsically linked to the biological properties of VEGF, and how this knowledge can guide the design of more effective strategies for therapeutic angiogenesis.

A biological role for VEGF-B has not yet been clearly established. VEGF-B knockout mice are viable, healthy and fertile, but whereas Bellomo et al. VEGF-B-deficient mice also have impaired development of pathophysiology when arthritis or hypoxic pulmonary hypertension are experimentally induced [ 53 ]. VEGF-C and its receptor, VEGFR3 Flt-4 , are strongly implicated in the formation of the lymphatic endothelium lymphangiogenesis. Transgenic mice overexpressing VEGF-C in keratinocytes of the skin epidermis develop enlarged lymphatic vessels, while mice overexpressing VEGF-A in the same location show only blood-vessel hyperplasia [ 54 ]. VEGF-C also stimulates angiogenesis in the mouse cornea [ 55 ], however, and also in rabbit models of ischemia in the hindlimb. VEGF-D is mitogenic in endothelial cells and promotes angiogenesis in vitro and in several models of angiogenesis in vivo [ 56 ]. VEGF-D also stimulates lymphangiogenesis in mice when overexpressed in skin keratinocytes and tumors [ 57 ], and it induces the survival and migration of lymphatic endothelial cells. The viral VEGF-Es encoded by different strains of the parapoxvirus Orf appear to be important for viral infection and its associated pathology. Viruses of the Orf genus cause a contagious pustular dermatitis in sheep and goats, which is transmissible to humans, and produces lesions characterized by extensive neovascularization, vascular dilation, and epidermal proliferation. VEGF-E NZ2 induces dermal vascularization and epidermal proliferation in sheep, and disruption of the VEGF-E NZ2 gene resulted in a marked decrease in the vascularization of viral lesions without impairing viral replication in the early stages of infection [ 58 ]. Drosophila PVFs and their receptor, PVR, have key roles in cell migration during two developmental processes [ 14 — 16 ]. Firstly, PVR is expressed by the border cells, a cluster of somatic follicle cells that migrate towards the oocyte during oogenesis; PVF1 is produced by oocytes and acts as a guidance cue for the PVR-expressing border cells during their migration [ 14 ]. PVR is expressed in the developing hemocytes during Drosophila embryogenesis, whereas PVF1, PVF2 and PVF3 are expressed along the hemocyte migratory route; inactivating mutations in either PVR or all three PVFs arrests hemocyte movement [ 16 ]. elegans , which lacks a vascular system, the VEGFR-like VER proteins are localized to cells of neural origin, suggesting a role in neurogenesis [ 17 ]. The recently identified VEGF and VEGFR homologs in the jellyfish P. carnea [ 18 ] are expressed in tubular structures of the gastrovascular system and in the endoderm during development at the stage when undifferentiated cells migrate and differentiate into plate cells. In this process, the differentiating plate cells interact with matrix and smooth muscle cells, a process analogous to the interaction of endothelial and vascular smooth muscle cells in angiogenesis. As nematodes and jellyfish lack both a vascular circulatory system and blood cells, the discovery of VEGF and VEGFR-like molecules in these species suggests that these proteins performed primordial functions in tubulogenesis and neurogenesis at an early evolutionary stage and only later developed more specialized roles in hematopoiesis and vascular development in more complex organisms. The role of VEGFs and VEGFRs in cell migration appears to be fundamental to their biological functions in invertebrate and vertebrate species. Although significant progress has been made towards elucidating the mechanisms mediating the angiogenic effects of VEGF-A, several formidable challenges lie ahead. The biological and signaling roles of the VEGF receptors, particularly VEGFR1 and neuropilin-1, have not yet been fully defined. Another key goal is the identification of the mechanisms underlying the role of VEGF-A in endothelial cell differentiation and early vascular development. An emergent area of interest is the study of VEGF and VEGFR homologs in invertebrates. A better understanding of how VEGF ligand-receptor systems function in Drosophila and C. elegans will shed light on the ancestral function of this family of molecules and may also generate novel insights into their biological roles in vertebrates. Another major goal in the future will be to clarify the distinct biological functions of different members of the VEGF family. A key area of ongoing research will be the role of VEGFs in human disease. As recent work on ALS demonstrates [ 48 , 49 ], it is likely that new insights into the importance of VEGFs for disease will continue to be generated. Consequently, the scope for using anti-VEGF approaches therapeutically will grow, and the challenge will be to develop more effective and economic ways to prevent VEGF-driven pathophysiological angiogenesis or to correct VEGF deficits. The future use of VEGF therapy for cardiovascular disease remains an enticing prospect but awaits confirmatory data from clinical studies.

Download PDF. VEGF is excreted in breast milk and decreased in the intestines of formula-fed murine and human neonates that succumb to necrotizing enterocolitis [ 32 — 34 ]. Frozen tissue was sectioned at 60 μm immunofluorescence staining with DAPI was performed as describe below. There are several potential mediators of tumour angiogenesis, including basic and acidic fibroblast growth factors, tumour necrosis factor- α and transforming factors- α and - β 1,2. |
