• Quinoline-based BODIPYs as potential EGFR/VEGFR-2 inhibitors. Lipinski's drug likeness of compounds 1–3 revealed promising physicochemical properties for oral bioavailability. The interaction was examined by molecular docking with binding energies in the order 3˃2˃1. HOMO and LUMO were also calculated using DFT method. vitro anticancer activity 1 3 on HeLa cells evaluated. This paper reports ...

BACKGROUND Receptor tyrosine kinases that include vascular endothelial growth factor (VEGFR)-1, VEGFR-2, and Tie-2 regulate cardiovascular development and physiological and pathological angiogenesis. We were interested in the phenotypic and functional characterization of peripheral blood cells expressing these receptors and their therapeutic potential in vascular injury. METHODS AND RESULTS V...

Vascular endothelial growth factor A (VEGF-A) is a key regulator of angiogenesis that binds to the receptors VEGFR-1 and VEGFR-2. It is well known that VEGF-A levels are increased in colorectal cancer (CRC) tissue compared to normal colorectal tissue, but little is known regarding the expression of the VEGFR-1 and -2 receptors. The aim of the present study was to perform a quantitative analysis...

PURPOSE To investigate the effects of anti-vascular endothelial growth factor (VEGF) antibody on the survival of retinal ganglion cell (RGC)-5 cells differentiated with staurosporine under oxidative stress. METHODS We used real-time polymerase chain reaction and Western blot to confirm the expression of VEGF, VEGF receptor (VEGFR)-1 and VEGFR-2 in RGC-5 cells differentiated with staurosporine...

Vascular endothelial growth factor-A (VEGF-A) and its 2 transmembrane tyrosine-kinase receptors, VEGFR-1 and VEGFR-2, constitute a ligand-receptor signaling system that is crucial for developmental angiogenesis. VEGF-B and placental growth factor (PlGF) activate VEGFR-1 selectively, however, mice lacking either ligand display only minor developmental defects. We hypothesized that the relative c...

The acute increase in vascular permeability produced by vascular endothelial growth factor (VEGF-A(165)) requires activation of endothelial Flk-1 receptors (VEGFR-2) and stimulation of platelet-activating factor (PAF) synthesis. Like PAF, VEGF-A(165) promotes translocation of P-selectin to the endothelial cell (EC) surface. However, the mechanisms involved remain unknown. By treating human umbi...

During pregnancy, VEGF (vascular endothelial growth factor) regulates in part endothelial angiogenesis and vasodilation. In the present study we examine the relative roles of VEGFRs (VEGF receptors) and associated signalling pathways mediating the effects of VEGF(165) on eNOS (endothelial nitric oxide synthase) activation. Despite equal expression levels of VEGFR-1 and VEGFR-2 in UAECs (uterine...
