Efficient clearance of apoptotic cells from the lung by alveolar macrophages is important for the maintenance of tissue structure and function. Lung tissue from humans with emphysema contains increased numbers of apoptotic cells and decreased levels of vascular endothelial growth factor (VEGF). Mice treated with VEGF receptor inhibitors have increased numbers of apoptotic cells and develop emph...

PURPOSE The aim of this study was to examine the localization and the changes in the amount of angiotensin-converting enzyme (ACE) and the relationship between the renin-angiotensin (RA) system and vascular endothelial growth factor (VEGF)/VEGF-receptor system in the retinas of diabetic rats. METHODS Immunohistochemical localization of ACE, VEGF, and VEGF-receptor fetal liver kinase-1 (Flk-1)...

The different members of the vascular endothelial growth factor (VEGF) family act as key regulators of endothelial cell function controlling vasculogenesis, angiogenesis, vascular permeability and endothelial cell survival. In this study, we have functionally characterized a novel member of the VEGF family, designated VEGF-E. VEGF-E sequences are encoded by the parapoxvirus Orf virus (OV). They...

Reduced tissue oxygen tension (hypoxia) is appreciated as an efficient stimulus for neovascularization. The effect of hypoxia on the very first stages of vascular development is, however, less well characterized. Here we show that hypoxic conditions (1% O2) potently stimulated formation of an extensive vascular network during a discrete stage of mouse embryonal stem cell differentiation. The mo...

BACKGROUND Vascular endothelial growth factor A stimulates angiogenesis, but is also pro-inflammatory and plays an important role in the development of neurological disease. This study aimed to investigate whether vascular endothelial growth factor A mRNA expression could be used as a marker for the prediction of susceptibility to multiple sclerosis and relate vascular endothelial growth factor...

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...

OBJECTIVE This study was undertaken to investigate the role of the angiogenic factors vascular endothelial growth factor and basic fibroblast growth factor in the development and progression of Barrett esophagus and adenocarcinomas of the esophagus and gastroesophageal junction. METHODS Vascular endothelial growth factor and basic fibroblast growth factor messenger RNA expression levels, rela...
