Flt-1 (vascular endothelial growth factor receptor-1) is essential for the vascular endothelial growth factor-Notch feedback loop during angiogenesis.

OBJECTIVE Vascular endothelial growth factor (VEGF) signaling induces Notch signaling during angiogenesis. Flt-1/VEGF receptor-1 negatively modulates VEGF signaling. Therefore, we tested the hypothesis that disrupted Flt-1 regulation of VEGF signaling causes Notch pathway defects that contribute to dysmorphogenesis of Flt-1 mutant vessels. APPROACH AND RESULTS Wild-type and flt-1(-/-) mouse e...

Vascular Endothelial Growth Factor Production is Regulated by Gene Polymorphisms

Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...

Involvement of Flt-1 tyrosine kinase (vascular endothelial growth factor receptor-1) in pathological angiogenesis.

Vascular endothelial growth factor (VEGF) and its two receptors, Fms-like tyrosine kinase 1 (Flt-1) (VEGFR-1) and KDR/Flk-1 (VEGFR-2), have been demonstrated to be an essential regulatory system for blood vessel formation in mammals. KDR is a major positive signal transducer for angiogenesis through its strong tyrosine kinase activity. Flt-1 has a unique biochemical activity, 10-fold higher aff...

In vitro combination therapy of pathologic angiogenesis using anti-vascular endothelial growth factor and anti-neuropilin-1 nanobodies

Objective(s): Emergence of resistant tumor cells to the current therapeutics is the main hindrance in cancer treatment. Combination therapy, which mixes two or more drugs, is a way to overcome resistant problems of cancer cells to current treatments.  Nanobodies are promising tools in cancer therapy due to their high affinity as well as high penetration to tumor sites....

MiR-103 regulates the angiogenesis of ischemic stroke rats by targeting vascular endothelial growth factor (VEGF)

Objective(s): To investigate the effect of miR-103 on the angiogenesis of ischemic stroke rats via targeting vascular endothelial growth factor (VEGF) at the molecular level. Materials and Methods: Rat models had received the middle cerebral artery occlusion (MCAO) or sham operation before grouping, and cell models of oxygen-glucose deprivation (OGD) were performed. FITC-dextran, matrigel, and ...
