neovascularization of the normally avascular cornea was associated with a notable increase in the expression of the major pro-angiogenic factors, inflammatory cytokines and proteases. the data supporting a causal role for vascular endothelial growth factor (vegf), inflammatory cytokines and matrix metalloproteinase (mmps) are extensive. anti-angiogenic/anti-inflammatory therapy is considered as...
The vascular endothelial growth factor (VEGF)-related factor, placental growth factor (PlGF), has been shown recently to play an important role in pathological VEGF-driven angiogenesis. In this study, we examine the effects of mPlGF/PlGF-2 overexpression in tumors grown from glioma cells containing a tetracycline-regulated mPlGF cDNA. Overexpression of mPlGF leads to increased tumor growth and ...
This article reviews the history and current status of vascular endothelial growth factor targeted therapy for the most common gynecologic malignancies - epithelial ovarian, endometrial and cervical cancers. The biologic rationale for targeting vascular endothelial growth factor (VEGF) for these disease sites is well-founded, and pre-clinical studies have supported the development of anti-VEGF ...
Background: According to the possible role of Vascular Endothelial Growth Factor (VEGF) in the incidence of oral lichen planus lesions, it seems necessary to evaluate it in patients with Oral Lichen Planus (OLP). Objective: The present study aims to investigate the level of VEGF in patients with OLP. Methods: In this systematic review and meta-analysis study, the search was conducted in online...
PURPOSE Vascular endothelial growth factor (VEGF) is a potent regulator of angiogenesis, which exerts direct effects on vascular endothelial cells, including endothelial cell proliferation and survival, tubulogenesis, and vascular permeability. In this study, we examined whether Neovastat, a naturally occurring multifunctional antiangiogenic drug, could inhibit the endothelial cell response to ...
The lymph node vasculature is essential to immune function, but mechanisms regulating lymph node vascular maintenance and growth are not well understood. Vascular endothelial growth factor (VEGF) is an important mediator of lymph node endothelial cell proliferation in stimulated lymph nodes. It is expressed basally in lymph nodes and up-regulated upon lymph node stimulation, but the identity of...
background angiogenesis is an important biological process involved in the proliferation of endothelial cells, tumor growth and metastasis. vascular endothelial growth factor (vegf) is considered as a prominent regulator of angiogenesis which exerts the aforementioned effect(s) through its respective receptors (vegfr1 and vegfr2). vegf receptors are targeted as a therapeutic candidate for cance...
Simple excision of pterygium, although very simple, is associated with variable postoperative recurrence rate which is especially high with bare sclera technique [1,2]. Recurrence of pterygium could be attributed to episcleral fibroblasts proliferation and neovascularization secondary to the traumatic and inflammatory processes following pterygium surgery. Histologically, pterygium comprises a ...
Background—Secretoneurin is a neuropeptide located in nerve fibers along blood vessels, is upregulated by hypoxia, and induces angiogenesis. We tested the hypothesis that secretoneurin gene therapy exerts beneficial effects in a rat model of myocardial infarction and evaluated the mechanism of action on coronary endothelial cells. Methods and Results—In vivo secretoneurin improved left ventricu...
Hemangiomas are tumors formed by hyper-proliferation of vascular endothelial cells. This is caused by elevated vascular endothelial growth factor (VEGF) signaling through VEGF receptor 2 (VEGFR2). Here we show that elevated VEGF levels produced by hemangioma endothelial cells are reduced by the mTOR inhibitor rapamycin. mTOR activates p70S6K, which controls translation of mRNA to generate prote...
