Gefitinib inhibits epidermal growth factor-independent angiogenesis, but the molecular mechanism underlying this inhibition has yet to be defined. Here we show that gefitinib dose-dependently inhibited chemotaxis of endothelial cells toward fibroblast growth factor-2 (FGF-2), but not toward vascular endothelial growth factor-A (VEGF-A). Gefitinib inhibited lamellipodium formation by endothelial...
Cannabinoids inhibit tumor angiogenesis in mice, but the mechanism of their antiangiogenic action is still unknown. Because the vascular endothelial growth factor (VEGF) pathway plays a critical role in tumor angiogenesis, here we studied whether cannabinoids affect it. As a first approach, cDNA array analysis showed that cannabinoid administration to mice bearing s.c. gliomas lowered the expre...
BACKGROUND The negative feedback system is an important physiological regulatory mechanism controlling angiogenesis. Soluble vascular endothelial growth factor (VEGF) receptor-1 (sFlt-1), acts as a potent endogenous soluble inhibitor of VEGF- and placenta growth factor (PlGF)-mediated biological function and can also form dominant-negative complexes with competent full-length VEGF receptors. ...
The Met receptor tyrosine kinase and its ligand, hepatocyte growth factor (HGF), are overexpressed and/or activated in a wide variety of human malignancies. Vascular endothelial growth factor (VEGF) receptors are expressed on the surface of vascular endothelial cells and cooperate with Met to induce tumor invasion and vascularization. EXEL-2880 (XL880, GSK1363089) is a small-molecule kinase inh...
In this work, nanobiohybrids of plasmonic gold nanoparticles (AuNP, anti-angiogenic) and a peptide mimicking the vascular endothelial growth factor (VEGF, pro-angiogenic) were assembled scrutinized in terms physicochemical characterization, including optical properties, surface charge, chemical structure morphology bioengineered metal nanoparticles, for their potential application as multifunct...
Vascular endothelial growth factor (VEGF) increases vascular permeability by stimulating endothelial Ca(2+) influx. Here we provide evidence that links VEGF-mediated increased permeability and endothelial intracellular Ca(2+) concentration ([Ca(2+)](i)) with diacylglycerol (DAG)-mediated activation of the transient receptor potential channels (TRPCs). We used the Landis-Michel technique to meas...
Vascular endothelial growth factors (VEGF) and their receptors (VEGFR) have been implicated to play important roles in tumor-associated angiogenesis and lymphangiogenesis, and hence in tumor growth and metastasis. We previously produced a number of fully human antibodies directed against VEGF receptor 2 (VEGFR2) and VEGF receptor 3 (VEGFR3) and showed that these antibodies are capable of inhibi...
We recently reported that chronic lymphocytic leukemia (CLL) cells synthesize and release vascular endothelial growth factor (VEGF) under normoxic and hypoxic conditions. CLL B cells also express VEGF membrane receptors (VEGF-R1 and VEGF-R2), suggesting that they use VEGF as a survival factor. To assess the mechanism of apoptosis resistance related to VEGF, we determined the impact of VEGF on C...
Background and Objective: Myocardial infraction can lead to loss of heart muscle cell, changes in ventricular function and structure, scar formation as well as leading the heart to ultimate stroke and its loss. This[J1] study aimed to investigate the effect of eight weeks of High-Intensity Interval Training (HIIT) on the gene expression of angiogenesis factors in ischemic rats. Materials and ...
