Microenvironmental VEGF concentration, not total dose, determines a threshold between normal and aberrant angiogenesis.
Use of long-term constitutive expression of VEGF for therapeutic angiogenesis may be limited by the growth of abnormal blood vessels and hemangiomas. We investigated the relationship between VEGF dosage and the morphology and function of newly formed blood vessels by implanting retrovirally transduced myoblasts that constitutively express VEGF164 into muscles of adult mice. Reducing VEGF dosage...
متن کاملMicroenvironmental VEGF distribution is critical for stable and functional vessel growth in ischemia.
The critical role of vascular endothelial growth factor (VEGF) expression levels in developmental angiogenesis is well established. Nonetheless, the effects of different local (microenvironmental) VEGF concentrations in ischemia have not been studied in the adult organism, and VEGF delivery to patients has been disappointing. Here, we demonstrate the existence of both lower and upper threshold ...
متن کاملVEGF and Tumor Angiogenesis
Based on successful preclinical data, over twenty antiangiogenic agents, alone or in combination with conventional therapies, are now in clinical trial. In the year 2000, close to 1,000 manuscripts describing the basic molecular and cellular mechanisms that allow for an angiogenic response have been published. The goal of this review is to summarize the reasons that angiogenesis re s e a rch ha...
متن کاملCritical role of microenvironmental factors in angiogenesis.
Therapeutic angiogenesis, which entails the induction of new blood vessels by the delivery of angiogenic growth factors, is a highly attractive approach to the treatment of ischemic diseases. However, it is becoming increasingly clear that this is not easily achieved, as the effects of angiogenic growth factors can differ markedly depending on the timing of their expression, on the shape of the...
متن کاملDose-dependent effect of pitavastatin on VEGF and angiogenesis in a mouse model of choroidal neovascularization.
PURPOSE To evaluate the relation between statin therapy, vascular endothelial growth factor (VEGF) expression, vascular leakage, and CNV size in experimentally induced choroidal neovascularization (CNV). METHODS Wild-type (C57 Bl/6J) mice received pitavastatin 0.18 mg/kg per day (group 1), 1.8 mg/kg per day (group 2) or 18 mg/kg per day (group 3) for 3 days before laser-induced CNV and contin...
