Background: This study aims to determine the differences of angiogenic markers sFlt-1 (soluble FMS-like tyrosine kinase-1), Placental Growth Factor (PlGF) and antioxidant (vitamin E) levels in pre-eclampsia compared with normotensive pregnancies. Methods: In a cross-sectional study performed on 40 normotensive pregnancies and 40 pre-eclampsia women, serum levels of sFlt-1, PlGF and vitamin E we...

Angiotensin II (Ang II) upregulates vascular endothelial growth factor (VEGF) and activates vascular inflammation. However, the decisive role of VEGF in Ang II-induced vascular inflammation and remodeling has not been addressed. Ang II infusion to wild-type mice increased local expression of VEGF and its receptors in cells of aortic wall and plasma VEGF, and caused aortic inflammation (monocyte...

As early as 20 weeks of gestation, preeclamptic women develop new-onset hypertension with proteinuria and display increased circulating factors, ranging from metabolic and proinflammatory to antiangiogenic in nature. These factors have been shown in various experimental models to possibly contribute to the development of hypertension in response to placental ischemia.1–4 A major focus of preecl...

The role of angiogenesis factors and hormonal profile in pregnant women with arterial hypertension has not been detailed studied, their interaction such patients determined at present time.The objective: to determine the features 1and 2 grade. Materials methods. A prospective study was conducted 88 women, which included: analysis clinical anamnestic characteristics pregnancy chronic (CAH) I tri...

BACKGROUND Therapeutic angiogenesis by delivery of vascular endothelial growth factor (VEGF) has attracted attention. However, the role and function of VEGF in experimental restenosis (neointimal formation) after vascular intraluminal injury have not been addressed. METHODS AND RESULTS We report herein that blockade of VEGF by soluble VEGF receptor 1 (sFlt-1) gene transfer attenuated neointim...

OBJECTIVES To assess the economic impact of introducing into clinical practice in the UK the soluble fms-like tyrosine kinase (sFlt-1) to placental growth factor (PlGF) ratio test for guiding the management of pre-eclampsia. METHODS We used an economic model estimating the incremental value of information, from a UK National Health Service payer's perspective, generated by the sFlt-1/PlGF rat...

Thrombotic microangiopathy (TMA) is a life-threatening condition that affects some, but not all, recipients of vascular endothelial growth factor (VEGF) inhibitors given as part of chemotherapy. TMA is also a complication of preeclampsia, a disease characterized by excess production of the VEGF-scavenging soluble VEGF receptor 1 (soluble fms-like tyrosine kinase 1; sFlt-1). Risk factors for VEG...

S-glutathionylation occurs when reactive oxygen or nitrogen species react with protein-cysteine thiols. Glutaredoxin-1 (Glrx) is a cytosolic enzyme which enzymatically catalyses the reduction in S-glutathionylation, conferring reversible signalling function to proteins with redox-sensitive thiols. Glrx can regulate vascular hypertrophy and inflammation by regulating the activity of nuclear fact...

The uterine response to 17beta-estradiol (E2) includes increased water retention, enhanced vascular permeability, DNA and RNA synthesis, and increased cellular mitosis. We have used the natural antagonist of vascular endothelial growth factor A (VEGF-A), sflt-1 (soluble form of flt-1), to determine whether the edematous and proliferative effects of E2 in the uterus are mediated by VEGF-A. Femal...
