Background: The pathogenesis of many diseases is correlated to irregularity in vascular endothelial growth factor (VEGF) expression. Results from several association studies show that variation in the level of VEGF expression is related to polymorphic sequences within the VEGF gene. Additionally, there are many studies showing that some gene polymorphisms significantly influence the pharmacokin...
There is widespread interest in the use of the angiogenic cytokine, vascular endothelial growth factor (VEGF), for the treatment of cardiovascular disease. The main paradigm for VEGF cardiovascular therapy is the stimulation of "therapeutic angiogenesis" in ischemic myocardial and peripheral vascular limb disease. In this review, approaches to VEGF therapy based on the therapeutic angiogenesis ...
GAS6, the product of a growth arrest specific (GAS) gene, is the ligand of the tyrosine kinase receptor Axl. GAS6 and Axl are both expressed in endothelial cells, where they are involved in many processes such as leukocyte transmigration through capillaries and neointima formation in injured vessels. Here, we show that Axl stimulation by GAS6 results in inhibition of the ligand-dependent activa...
Background: Nasal inflammatory disorders such as chronic rhinosinusitis and nasal polyp are among the most prevalent complications with high socioeconomic costs. Vascular Endothelial Growth Factor (VEGF) plays a key role in angiogenesis and cell proliferation. In the present study the effect of VEGF on the development and prognosis of chronic rhinosinusitis and nasal p...
Vascular endothelial growth factor (VEGF-A) is a crucial stimulator of vascular cell migration and proliferation. Using bone marrow-derived human adult mesenchymal stem cells (MSCs) that did not express VEGF receptors, we provide evidence that VEGF-A can stimulate platelet-derived growth factor receptors (PDGFRs), thereby regulating MSC migration and proliferation. VEGF-A binds to both PDGFRalp...
INTRODUCTION Vascular endothelial growth factor (VEGF) is expressed in osteoarthritic articular cartilage. However, the pattern of VEGF expression throughout the whole life cycle of articular cartilage is not well elucidated. The aim of the study was to investigate the spatiotemporal expression of VEGF and its receptors, vascular endothelial growth factor receptor-1 (VEGFR1) and vascular endoth...
PURPOSE To determine the effect of vascular endothelial growth factor VEGF Trap (Regeneron Pharmaceuticals, Tarrytown, NY), a humanized soluble vascular endothelial growth factor (VEGF) receptor protein, and radiation (RT) on tumor growth in U87 glioblastoma xenografts in nude mice. METHODS AND MATERIALS U87 cell suspensions were implanted subcutaneously into hind limbs of nude mice. VEGF Tra...
Infection by pneumococci causes an acute inflammatory response associated with neutrophil influx, increased vascular permeability, and edema. Vascular endothelial growth factor (VEGF) is one of the most potent regulators of endothelial permeability. In vitro stimulation of neutrophils showed that pneumococci and purified pneumococcal cell wall induce VEGF secretion, independent of the presence ...
There is increasing evidence that hormones play an important role in the control of endothelial cell function and growth by regulating the production of vascular endothelial growth factor (VEGF). VEGF regulates vascular permeability and represents the most powerful growth factor for endothelial cells. In the normal anterior pituitary, VEGF has been detected only in folliculostellate (FS) cells....
Vascular endothelial cells are ordinarily quiescent in adult humans and divide less than once per decade. When tumors reach a size of about 0.2-2.0mm in diameter, they become hypoxic and limited in size in the absence of angiogenesis. There are about 30 endogenous pro-angiogenic factors and about 30 endogenous anti-angiogenic factors. In order to increase in size, tumors undergo an angiogenic s...
