The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445)

A family of conserved cell surface receptors that contain EPIDERMAL GROWTH FACTOR repeats in their extracellular domain and ANKYRIN repeats in their cytoplasmic domains. The cytoplasmic domain of notch receptors is released upon ligand binding and translocates to the CELL NUCLEUS where it acts as transcription factor.

Neuropilins are 140-kDa vertebrate cell surface receptors that bind neuronal guidance molecules during neural development and axonal outgrowth, and modulate VEGF-mediated angiogenesis. NEUROPILIN-1 and NEUROPILIN-2 differ in their binding specificities, and are distributed complementarily in regions of the developing nervous system. Neuropilins are receptors for secreted CLASS 3 SEMAPHORINS as well as for vascular endothelial growth factors, and may form hetero- or homodimers. They may also interact synergistically with plexins and with VEGF RECEPTORS to form receptor complexes with distinct affinities and specificities. Neuropilin binding specificity is determined by CUB and coagulation-factor-like domains in the extracellular portion of the molecule, while a MAM domain is essential for SIGNAL TRANSDUCTION.

This family includes alpha 1-antitrypsin, angiotensinogen, ovalbumin, antiplasmin, alpha 1-antichymotrypsin, thyroxine-binding protein, complement 1 inactivators, antithrombin III, heparin cofactor II, plasminogen inactivators, gene Y protein, placental plasminogen activator inhibitor, and barley Z protein. Some members of the serpin family may be substrates rather than inhibitors of SERINE ENDOPEPTIDASES, and some serpins occur in plants where their function is not known.

DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

COMP-Ang1: a designed angiopoietin-1 variant with nonleaky angiogenic activity. (1/26)

Angiopoietin-1 (Ang1) has potential therapeutic applications in inducing angiogenesis, enhancing endothelial cell survival, and preventing vascular leakage. However, production of Ang1 is hindered by aggregation and insolubility resulting from disulfide-linked higher-order structures. Here, by replacing the N-terminal portion of Ang1 with the short coiled-coil domain of cartilage oligomeric matrix protein (COMP), we have generated a soluble, stable, and potent Ang1 variant, COMP-Ang1. This variant is more potent than native Ang1 in phosphorylating the tyrosine kinase with Ig and epidermal growth factor homology domain 2 (Tie2) receptor and Akt in primary cultured endothelial cells, enhancing angiogenesis in vitro and increasing adult angiogenesis in vivo. Thus, COMP-Ang1 is an effective alternative to native Ang1 for therapeutic angiogenesis in vivo. (+info)

Current methods for assaying angiogenesis in vitro and in vivo. (2/26)

Angiogenesis, the development of new blood vessels from an existing vasculature, is essential in normal developmental processes and in numerous pathologies, including diabetic retinopathy, psoriasis and tumour growth and metastases. One of the problems faced by angiogenesis researchers has been the difficulty of finding suitable methods for assessing the effects of regulators of the angiogenic response. The ideal assay would be reliable, technically straightforward, easily quantifiable and, most importantly, physiologically relevant. Here, we review the advantages and limitations of the principal assays in use, including those for the proliferation, migration and differentiation of endothelial cells in vitro, vessel outgrowth from organ cultures and in vivo assays such as sponge implantation, corneal, chamber, zebrafish, chick chorioallantoic membrane (CAM) and tumour angiogenesis models.

Acclimatization to 4100 m does not change capillary density or mRNA expression of potential angiogenesis regulatory factors in human skeletal muscle. (3/26)

Increased skeletal muscle capillary density would be a logical adaptive mechanism to chronic hypoxic exposure. However, animal studies have yielded conflicting results, and human studies are sparse. Neoformation of capillaries is dependent on endothelial growth factors such as vascular endothelial growth factor (VEGF), a known target gene for hypoxia inducible factor 1 (HIF-1). We hypothesised that prolonged exposure to high altitude increases muscle capillary density and that this can be explained by an enhanced HIF-1alpha expression inducing an increase in VEGF expression. We measured mRNA levels and capillary density in muscle biopsies from vastus lateralis obtained in sea level residents (SLR; N=8) before and after 2 and 8 weeks of exposure to 4100 m altitude and in Bolivian Aymara high-altitude natives exposed to approximately 4100 m altitude (HAN; N=7). The expression of HIF-1alpha or VEGF mRNA was not changed with prolonged hypoxic exposure in SLR, and both genes were similarly expressed in SLR and HAN. In SLR, whole body mass, mean muscle fibre area and capillary to muscle fibre ratio remained unchanged during acclimatization. The capillary to fibre ratio was lower in HAN than in SLR (2.4+/-0.1 vs 3.6+/-0.2; P<0.05). In conclusion, human muscle VEGF mRNA expression and capillary density are not significantly increased by 8 weeks of exposure to high altitude and are not increased in Aymara high-altitude natives compared with sea level residents.

Bartonella adhesin a mediates a proangiogenic host cell response. (4/26)

Bartonella henselae causes vasculoproliferative disorders in humans. We identified a nonfimbrial adhesin of B. henselae designated as Bartonella adhesin A (BadA). BadA is a 340-kD outer membrane protein encoded by the 9.3-kb badA gene. It has a modular structure and contains domains homologous to the Yersinia enterocolitica nonfimbrial adhesin (Yersinia adhesin A). Expression of BadA was restored in a BadA-deficient transposon mutant by complementation in trans. BadA mediates the binding of B. henselae to extracellular matrix proteins and to endothelial cells, possibly via beta1 integrins, but prevents phagocytosis. Expression of BadA is crucial for activation of hypoxia-inducible factor 1 in host cells by B. henselae and secretion of proangiogenic cytokines (e.g., vascular endothelial growth factor). BadA is immunodominant in B. henselae-infected patients and rodents, indicating that it is expressed during Bartonella infections. Our results suggest that BadA, the largest characterized bacterial protein thus far, is a major pathogenicity factor of B. henselae with a potential role in the induction of vasculoproliferative disorders.

Vascular endothelial growth factor and angiogenesis. (5/26)

Angiogenesis is a hallmark of wound healing, the menstrual cycle, cancer, and various ischemic and inflammatory diseases. A rich variety of pro- and antiangiogenic molecules have already been discovered. Vascular endothelial growth factor (VEGF) is an interesting inducer of angiogenesis and lymphangiogenesis, because it is a highly specific mitogen for endothelial cells. Signal transduction involves binding to tyrosine kinase receptors and results in endothelial cell proliferation, migration, and new vessel formation. In this article, the role of VEGF in physiological and pathological processes is reviewed. We also discuss how modulation of VEGF expression creates new therapeutic possibilities and describe recent developments in this field. (+info)

The soluble extracellular domain of EphB4 (sEphB4) antagonizes EphB4-EphrinB2 interaction, modulates angiogenesis, and inhibits tumor growth. (6/26)

The receptor tyrosine kinase EphB4 and its ligand EphrinB2 play a crucial role in vascular development during embryogenesis. The soluble monomeric derivative of the extracellular domain of EphB4 (sEphB4) was designed as an antagonist of EphB4/EphrinB2 signaling. sEphB4 blocks activation of EphB4 and EphrinB2; suppresses endothelial cell migration, adhesion, and tube formation in vitro; and inhibits the angiogenic effects of various growth factors (VEGF and bFGF) in vivo. sEphB4 also inhibits tumor growth in murine tumor xenograft models. sEphB4 is thus a therapeutic candidate for vascular proliferative diseases and cancer.

New insights into the biology of preeclampsia. (7/26)

Despite recent research progress, the biology of preeclampsia is still poorly understood and neither effective prediction nor causal therapy have yet emerged. Nevertheless, recent studies have documented new and exciting pathophysiological mechanisms for the origin and development of preeclampsia. These studies provide a more differentiated view on alterations of particular peptide systems with strong impact on angiogenesis and cardiovascular regulation in this pregnancy disorder. With the identification of the antiangiogenic factor soluble fms-like tyrosine kinase 1 and the agonistic autoantibody to the angiotensin II type 1 receptor, two factors have been described with a clear linkage to the development of the disease. This review focuses on the most recent and relevant insights into the biology of preeclampsia and develops hypotheses regarding possible links between the reported aspects of preeclampsia. (+info)

A cell-based model exhibiting branching and anastomosis during tumor-induced angiogenesis. (8/26)

This work describes the first cell-based model of tumor-induced angiogenesis. At the extracellular level, the model describes diffusion, uptake, and decay of tumor-secreted pro-angiogenic factor. At the cellular level, the model uses the cellular Potts model based on system-energy reduction to describe endothelial cell migration, growth, division, cellular adhesion, and the evolving structure of the stroma. Numerical simulations show: 1), different tumor-secreted pro-angiogenic factor gradient profiles dramatically affect capillary sprout morphology; 2), average sprout extension speeds depend on the proximity of the proliferating region to the sprout tip, and the coordination of cellular functions; and 3), inhomogeneities in the extravascular tissue lead to sprout branching and anastomosis, phenomena that emerge without any prescribed rules. This model provides a quantitative framework to test hypotheses on the biochemical and biomechanical mechanisms that control tumor-induced angiogenesis. (+info)

This study investigated the effects of Hsp90 inhibitors on client protein expression and key cellular functions required for tumor angiogenesis. (aacrjournals.org)
Thus, we identify Hsp90 inhibitors as important regulators of many aspects of tumor angiogenesis (and potentially lymphangiogenesis) and suggest that they may provide therapeutic benefit not only via direct effects on tumor cells but also indirectly by inhibiting the production of angiogenic cytokines and responses of activated endothelial cells that contribute to tumor progression and metastasis. (aacrjournals.org)
Chromatin remodeling agents such as histone deacetylase inhibitors have been shown to modulate gene expression in tumor cells and inhibit tumor growth and angiogenesis. (aacrjournals.org)
These results suggest that the combination of histone deacetylase inhibitors and VEGF receptor inhibitors may target multiple pathways in tumor progression and angiogenesis and represents a novel therapeutic approach in cancer treatment. (aacrjournals.org)
Attempts to target these critical processes involved in tumor angiogenesis have led to the clinical development of angiogenesis inhibitors. (aacrjournals.org)
The development of tumor-specific anti-angiogenic therapy was also catalyzed by the finding that inhibitors of angiogenesis appeared immune to the development of drug resistance by the tumor cells, a major restrain in current chemotherapy. (northwestern.edu)

Studies have show that ursolic acid suppresses tumor formation, inhibits tumor growth, induces apoptosis, inhibits angiogenesis, inhibits signaling and activation pathways, induces tumor cell differentiation, and suppresses growth factor expression. (essense-of-life.com)
Recent research has suggested that plant polyphenols (which includes ursolic acid) might be used to sensitize tumor cells to chemotherapeutic agents and radiation therapy by inhibiting pathways that lead to treatment resistance. (essense-of-life.com)

In particular, we have investigated ribozymes that target the mRNA of the vascular endothelial growth factor (VEGF) receptors because VEGF signaling is an important mediator of tumor angiogenesis and metastasis. (aacrjournals.org)
Increased bone marrow angiogenesis and vascular endothelial growth factor (VEGF) levels are of adverse prognostic significance in patients with multiple myeloma (MM). VEGF, a soluble circulating angiogenic molecule, acts via receptor tyrosine kinases, including VEGF receptor 2. (aacrjournals.org)
One such pathway involves the vascular endothelial growth factor (VEGF) signal transduction, which is critical in angiogenesis and also important in tumor proliferation. (cancernetwork.com)
The vascular endothelial growth factor (VEGF) and the platelet-derived growth factor C (PDGF-C) are agents of great interest on tumour angiogenesis and may be modulated by the HIF-1. (usp.br)
The results were correlated with angiogenesis assessed by micro-vessel density (MVD) for CD34, CD105, VEGF and PDGF-C, with endothelial cell proliferation by nuclear staining for KI-67, and also with survival. (usp.br)
