OBJECTIVES Vascular endothelial growth factor (VEGF) promotes angiogenesis, mediates vascular permeability, and activates and recruits monocytes. VEGF is produced in activated alveolar macrophages, in epithelioid cells, and in multinuclear giant cells of pulmonary sarcoid granulomas. Recent reports have shown that a polymorphism at - 627 of the VEGF gene is related to VEGF protein production, a...

To evaluate whether beta-catenin signaling has a role in the regulation of angiogenesis in colon cancer, a series of angiogenesis-related gene promoters was analyzed for beta-catenin/TCF binding sites. Strikingly, the gene promoter of human vascular endothelial growth factor (VEGF, or VEGF-A) contains seven consensus binding sites for beta-catenin/TCF. Analysis of laser capture microdissected h...

INTRODUCTION Large osseous defect remains a serious clinical problem due to the lack of sufficient blood supply and it has been proposed that this situation can be relieved by accelerating the formation of new vessels in the process of bone defect repair. The aim of this study was to develop a new type of artificial bone by transferring the VEGF gene into marrow stromal cells (MSCs) and seeding...

BACKGROUND Pulmonary arterial hypertension is characterized by increased pulmonary vascular resistance secondary to a decrease in the caliber and number of pulmonary vascular channels. We hypothesized that the targeted overexpression of an angiogenic factor within the lung would potentially minimize the development and progression of pulmonary arterial hypertension by preventing the loss of exi...

Background: Recurrent pregnancy loss (RPL) is a common problem among couples, and acquired thrombophilia is the well-known etiology of RPL. The aim of this study was to establish the association between inherited thrombophilic gene polymorphisms and RPL. Methods: This case-control study was conducted on 50 women with unexplained RPL and 50 parous women with no history of miscarriage (age range...

background: vascular endothelial growth factor (vegf) has a key role in angiogene-sis and in transplantation. the level of vegf is related to the differences in the dna sequence of its promoter region. objectives: in this study, the association between the combination of vegf –1154 g and –2578 c alleles and vegf production by lps-stimulated pbmcs was investigated. in addition; the relationship ...

Growth factors like bone morphogenetic protein 2 (BMP-2) and vascular endothelial growth factor (VEGF) play an important role in bone remodeling and fracture repair. Therefore, with respect to tissue engineering, an artificial graft should have no negative impact on the expression of these factors. In this context, the aim of this study was to analyze the impact of poly(L-lactic acid) (PLLA) na...

VEGF-B KO rats. VEGF-B gene-deleted rats of Sprague-Dawley background were generated using a zinc-finger nuclease based technique by Sigma Advanced Genetic Engineering Labs, Sigma-Aldrich Biotechnology (St. Louis, Missouri, USA) (Cui et al, 2011; Geurts et al, 2009). A 22-base pair segment of exon 1 of the rat VEGF-B gene was replaced with a bacterial lacZ gene with a nuclear localization signa...

Dysregulation of VEGF-A bioavailability has been implicated in the development of lung injury/fibrosis, exemplified by Idiopathic Pulmonary Fibrosis (IPF). VEGF-A is a target of the hypoxic response via its translational regulation by HIF-1α. The role of hypoxia and hyperoxia in the development and progression of IPF has not been explored. In normal lung (NF) and IPF-derived fibroblasts (FF) VE...
