Endothelium-derived nitric oxide (NO) is a mediator of angiogenesis. Vascular endothelial growth factor (VEGF) stimulates the release of NO from cultured human umbilical venous endothelial cells and upregulates the expression of nitric oxide synthase (NOS).1,2 Segments of rabbit thoracic aorta release NO in response to VEGF; preincubation with L-arginine increases basal and VEGFstimulated NO re...

Purpose: To investigate the differential expressions of transforming growth factor-β1 (TGF-β1), hypoxia inductive factor-1 (HIF-1), vascular endothelial factor (VEGF), α-smooth muscle protein (α-SMA) and E-cadherin in renal tissues neonatal rat model hydronephrosis.Methods: The rats (90) were randomly divided into sham group group. further two subgroups: week 1 12 after relief obstruction, with...

Increased vascular endothelial growth factor (VEGF) expression is associated with colon cancer metastases. We hypothesized that inhibition of VEGF receptor activity could inhibit colon cancer liver metastases. BALB/c mice underwent splenic injection with CT-26 colon cancer cells to generate metastases. Mice received daily i.p. injections of vehicle, tyrosine kinase inhibitor for Flk-1/KDR (SU54...

Vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) are potent angiogenic factors that have been used clinically to induce angiogenesis. However, concerns have been raised about VEGF because of its proinflammatory actions, which include enhancing the adhesion of leukocytes to endothelial cells. We have examined the possible antiinflammatory effects of HGF on the vascula...

The role of paracrine signaling by vascular endothelial growth factor (VEGF) in the formation and maintenance of blood vessels has been studied extensively. In this issue, Lee et al. (2007) report unexpected results showing that endogenous VEGF produced by endothelial cells is also crucial for vascular homeostasis.

Vascular endothelial growth factor (VEGF) is a pluripotent growth and permeability factor that has a broad impact on endothelial cell function. The lung tissue is very rich in this protein; many different lung cells produce VEGF and also respond to VEGF. VEGF is critical for the development of the lung and serves as a maintenance factor during adult life. In addition to the physiological functi...

The tetrapeptide Arg-Leu-Tyr-Glu (RLYE) is known to inhibit vascular endothelial growth factor-A (VEGF-A)-induced angiogenesis in vitro. Herein, we examined its underlying mechanism and antitumor activity associated with vascular remodeling. RLYE inhibited VEGF-A-induced angiogenesis in a mouse model and suppressed VEGF-A-induced angiogenic signal cascades in human endothelial cells. However, R...

Background: Vascular endothelial growth factor (VEGF) is an angiogenic growth factor that is produced by different tissues, including the endometrium and ovary. VEGF is involved in many processes related to reproductive physiology, including angiogenesis, which is essential for implantation and placentation. It has been suggested that VEGF may be the angiogenic factor responsible for the implan...

The authors report a novel, alternative approach to treat malignant peritoneal mesothelioma (MPeM) targeting, vascular endothelial growth factor (VEGF) using anti-VEGF (bevacizumab) chemotherapy combination.
