Role of VEGF in Kidney Development, Microvascular Maintenance and Pathophysiology of Renal Disease
Vascular endothelial growth factor, VEGF, is essential for endothelial cell differentiation (vasculogenesis) and for the sprouting of new capillaries from preexisting vessels (angiogenesis). In addition, there is strong evidence that VEGF is a survival factor allowing the cells to survive and proliferate under conditions of extreme stress. Hypoxia is a key regulator of VEGF gene expression. Bes...
متن کاملGlomerular-specific alterations of VEGF-A expression lead to distinct congenital and acquired renal diseases.
Kidney disease affects over 20 million people in the United States alone. Although the causes of renal failure are diverse, the glomerular filtration barrier is often the target of injury. Dysregulation of VEGF expression within the glomerulus has been demonstrated in a wide range of primary and acquired renal diseases, although the significance of these changes is unknown. In the glomerulus, V...
متن کاملVascular endothelial growth factor expression and glomerular endothelial cell loss in the remnant kidney model.
BACKGROUND Vascular endothelial growth factor (VEGF) is constitutively expressed in the glomerulus where it may have a role in the maintenance of capillary endothelial cell integrity. The present study sought to examine changes in VEGF expression in a model of progressive renal disease and to assess the effects of angiotensin converting enzyme (ACE) inhibition. METHODS Subtotal nephrectomized...
متن کاملVEGF165b overexpression restores normal glomerular water permeability in VEGF164-overexpressing adult mice.
Vascular endothelial growth factor (VEGF)-A, a family of differentially spliced proteins produced by glomerular podocytes, maintains glomerular filtration barrier function. The expression of VEGF molecules is altered in human nephropathy. We aimed to determine the roles of the angiogenic VEGF(164) isoform, and the antiangiogenic VEGF(165)b isoform in mature, adult glomeruli in vivo using condit...
متن کاملMori cortex prevents kidney damage through inhibiting expression of inflammatory factors in the glomerulus in streptozocin-induced diabetic rats
Objective(s): It has been widely reported that Mori cortex extract (MCE) is used for the treatment of diabetes mellitus in traditional medicine. The present study was designed to investigate its mechanism of action in the treatment of diabetic nephropathy (DN). We assessed whether MCE preventive treatment ameliorates kidney damage in high-fat diet and streptozotocin (STZ)-induced type 2 diabeti...
