Vascular endothelial growth factor (VEGF) is necessary for microvasculature development and important for growth and spread of pancreatic tumors. Functional polymorphism of VEGF gene at position C-460T and G+405C may influence VEGF serum level. VEGF gene polymorphisms at position C-460T and G+405C were evaluated in 85 patients with pancreatic adenocarcinoma (PA), 72 - with chronic pancreatitis ...

PURPOSE Angiotensin II (AII) has been shown to play a role in many vascular diseases. In the study described, the effect of AII on vascular endothelial growth factor (VEGF) expression and related intracellular signaling mechanism was investigated in bovine retinal microcapillary pericytes. METHODS Cultured bovine retinal microvascular endothelial cells and pericytes were prepared. VEGF expres...

PURPOSE Glucocorticoids such as prednisone, hydrocortisone, and dexamethasone are known to provide some clinical benefit for patients with hormone-refractory prostate cancer. However, the underlying mechanisms by which glucocorticoids affect hormone-refractory prostate cancer progression are not well established as yet. Our previous study has shown that glucocorticoids inhibit tumor angiogenesi...

Background: Vascular endothelial growth factor A (VEGFA) plays a key role in angiogenesis during human placenta formation and its abnormal expressions have been reported in placental tissues of women with recurrent miscarriage (RM). Objective: The aim of this study was to evaluate the correlation of polymorphism of VEGF1154 G/A gene in RM and In Vitro Fertiliz...

BACKGROUND Hypoxia and nitric oxide (NO) play important roles in the onset and progression of glaucoma. Vascular endothelial growth factor (VEGF) is one of the main factors responsive to hypoxia and NO. In this study, we investigated the association between the BstUI C/T VEGF gene polymorphism and primary open angle glaucoma (POAG). METHODS 60 POAG patients and 78 healthy volunteers were enro...

This study investigated the effects of vascular endothelial growth factor (VEGF) -634G>C and endothelial nitric oxide synthase (eNOS) 894G>T genetic polymorphisms, their gene-gene interaction and their interactions with steroid use on the risk of osteonecrosis of the femoral head (ONFH). An age-matched case-control study was conducted with 174 cases and 174 controls. VEGF and eNOS genotypes wer...

PURPOSE Vascular endothelial growth factor (VEGF), an important regulator of angiogenesis and vascular permeability, is involved in various steps of ovarian carcinogenesis. Gene polymorphisms within the gene encoding VEGF were shown to be independently associated with an adverse outcome in various malignancies. No data are available for ovarian cancer. EXPERIMENTAL DESIGN In the present multi...

Research question Maternal alcohol consumption produces fetal retardation and malformations, probably associated with placental defects. Does perigestational up to organogenesis lead abnormal placentation embryo growth restriction by disrupting the vascular endothelial factor (VEGF) system in embryo–placental development? Design Female mice were treated 10% ethanol drinking water before day 10 ...

Background: Vascular endothelial growth factor (VEGF) have a vital role in the molecular genetic eventsof angiogenesis and vasculogenesis, so it is involved development of cancer. Single nucleotidepolymorphisms (SNP) VEGF gene has been announced as risk colorectal Bevacizumab(BEV) an inhibitor that curb binding to its receptors obstructing angiogenesisprocess. Objective: The ideal goal ongoing ...

PURPOSE To review the biology of renal cell carcinoma (RCC) and the clinical results of vascular endothelial growth factor (VEGF) blockade in metastatic RCC. METHODS A review of relevant published literature regarding VEGF, von Hippel-Lindau (VHL) gene inactivation, and VEGF overexpression in RCC was performed. Further, a review of the mechanism, toxicity, and clinical development of VEGF-tar...
