BACKGROUND For the successful therapeutic use of inhibitors of the vascular endothelial growth factor receptor (VEGFR) pathway detailed knowledge of the mechanisms leading to tumor progression is indispensable. The main goal of this study was to determine the relevance of the VEGFR-2 activating pathway for colon carcinoma (CC) metastasis. The initial event is ligand-induced receptor activation ...
BACKGROUND There is an unmet need for proangiogenic therapeutic molecules for the treatment of tissue ischemia in cardiovascular diseases. However, major inducers of angiogenesis such as vascular endothelial growth factor (VEGF/VEGF-A) have side effects that limit their therapeutic utility in vivo, especially at high concentrations. Angiopoietin-1 has been considered to be a blood vessel stabil...
Vascular permeability factor (VPF)/VEGF is a potent multifunctional cytokine and growth factor that has critical roles in vasculogenesis and in both physiological and pathological angiogenesis. Because it has been recently shown that the neurotransmitter dopamine at pharmacological dose can inhibit VEGF/VPF-mediated microvascular permeability, proliferation, and migration of endothelial cells i...
Pulmonary emphysema, a significant global health problem, is characterized by a loss of alveolar structures. Because VEGF is a trophic factor required for the survival of endothelial cells and is abundantly expressed in the lung, we hypothesized that chronic blockade of VEGF receptors could induce alveolar cell apoptosis and emphysema. Chronic treatment of rats with the VEGF receptor blocker SU...
PURPOSE The vascular endothelial growth factor (VEGF) family is involved in vascular leakage and angiogenesis in diabetic retinopathy (DR) in the eye, but may also have physiological functions. Based on the hypothesis that differential VEGF receptor (VEGFR) expression in the retina is an important determinant of effects of VEGF, this study was conducted to investigate VEGFR expression in the di...
Herein, we report that vascular endothelial growth factor A (VEGF-A) engages the PI3K/Akt pathway by a previously unknown mechanism that involves three tyrosine kinases. Upon VEGF-A-dependent activation of VEGF receptor-2 (VEGFR-2), and subsequent TSAd-mediated activation of Src family kinases (SFKs), SFKs engage the receptor tyrosine kinase Axl via its juxtamembrane domain to trigger ligand-in...
BACKGROUND Vascular endothelial growth factor (VEGF) receptor-2 is the major mediator of the mitogenic, angiogenic, and vascular hyperpermeability effects of VEGF on breast tumors. Overexpression of VEGF and VEGF receptor-2 is associated with the degree of pathomorphosis of the tumor tissue and unfavorable prognosis. In this study, we demonstrate that non-invasive quantification of the degree o...
Wstęp Angiogeneza nowotworowa jest procesem regulowanym przez wiele cytokin i czynników wzrostu, spośród których znaczącą rolę odgrywają czynnik wzrostu śródbłonka naczyń (<i>vascular endothelial growth factor</i> – VEGF), drugi rozpuszczalny receptor dla śródbłonkowego czynnika (<i>soluble vascular factor 2</i> sVEGFR-2) galektyna-3. Dane literaturowe dotyczące oceny zm...
