2016年11月21日 · By trans well assay and angiogenesis assay, Nrf2 knockout significantly inhibited the migration and vascular tube formation of BMECs. These findings suggest that the interplay between Nrf2 and VEGF can contribute to VH-induced angiogenesis in …

2024年1月19日 · Endothelial cells express neuropilin 1 (NRP1), endoglin (ENG) and vascular endothelial growth factor receptor 2 (VEGFR2), which regulate VEGF-A-mediated vascular development and angiogenesis....

2016年7月27日 · Vascular endothelial growth factor receptor (VEGFR) signalling is tightly regulated at different levels: ligand and receptor expression, the presence of...

2019年2月2日 · Inhibition of vascular endothelial growth factor (VEGF) or its corresponding receptor (VEGFR) has been validated as an efficacious antiangiogenetic approach for cancer treatment. More recently, neuropilins (NRPs), the essential coreceptors for VEGF, have also been shown to have a significant role in VEGF signaling.

2006年8月15日 · In this study, we show that both VEGF-A and VEGF-C induce the interaction of NRP2 with VEGFR-2. This interaction correlated with an enhancement of the VEGFR-2 phosphorylation threshold. Overexpression of NRP2 in primary human endothelial cells promoted cell survival induced by VEGF-A and VEGF-C.

2024年4月19日 · In vitro studies indicated that Nrf2 overactivation restricted VEGF signaling in endothelial progenitor cells. The findings from broiler embryos suggest an association between plexiform lesion development and impaired VEGF system due to aberrant activation of Nrf2.

Vascular endothelia growth factor VEGF (VEGF-A or VEGF165) is a potent angiogenic factor that also signals neuroprotection through activation of its cognate receptor VEGFR-2. In this capacity, VEGF signaling can rescue neurons from the damage ...

2021年4月16日 · VEGFR2 can interact with VEGFR2 co-receptors such as heparan sulfate proteoglycans (HSPGs) and neuropilin 2 (NRP2), but the exact roles of these co-receptors, or of sulfatase 2 (SULF2), an enzyme that removes sulfate groups from HSPGs and inhibits HSPG-mediated uptake of very low density lipoprotein (VLDL), in angiogenesis and tip cell biology a...

2016年11月21日 · Immunohistochemistry indicated that Nrf2 and VEGF were highly expressed in human brain AVM tissues. In vivo, we established a VH model in both wild-type (WT) and siRNA-mediated Nrf2 knockdown...

In the human VEGFR-2, there are 18 N-linked glycosylation sites, 15 phosphorylation sites, and many ATP binding sites and substrate binding sites, which play important roles in post-translational modifications of VEGFR-2, protein folding, protein activation, and cellular attachment, and can further modulate the function of VEGFR-2 (Croci et al ...
