General description

Vasohibin-1 is an endothelium-derived negative feedback regulator of angiogenesis. Vasohibin-1 inhibited migration, proliferation, and network formation by ECs in culture, as well as angiogenesis in vivo, and Vasohibin-1 was selective for endothelial cells and its influence was eliminated by hypoxia or TNF-alpha interaction. Vasohibin is preferentially expressed in endothelial cells and does not appear to promote proliferation or tumor growth when over expressed. Vasohibin-1 expression is induced by VEGF expression and its effects are mediated through VEGF-R2 independent of VEGF-R1 and Vasohibin-1 may directly influence the expression of VEGF-R2. Because the inhibition effects of Vasohibin-1 are nullified by hypoxia and various cytokines it is thought that this is how tumors escape this built-in negative regulator of angiogenesis. Vasohibin-1 is highly expressed in fetal organs and the endothelial cells during development, and also expressed in the brain and placental and microvessels endothelial cells of atherosclerotic lesions in the adult.

Immunogen

KLH-conjugated linear peptide corresponding to Human Vasohibin-1.

Application

Functional Activity Assay: A representative lot of this antibody induced cellular senescence (Miyashita, H., et al. (2012) PLOS ONE. 7(10):e46459).

Western Blotting Analysis: A representative lot of this antibody detected Vasohibin-1 in HUVECs transfected with control siRNA, but not in HUVECs transfected with Vasohibin-1 siRNA (Miyashita, H., et al. (2012) PLOS ONE. 7(10):e46459).

Western Blotting Analysis: A representative lot of this antibody detected Vasohibin-1 (KIAA1036 protein referenced in publication) in VEGF-stimulated HUVECs and GM7373 transfected cell lysate (Watanabe, K,, et al. (2004) JCI. 114(7):898-907).

Immunohistochemistry Analysis: A representative lot of this antibody detected Vasohibin-1 (KIAA1036 protein referenced in publication) in human placenta tissue (Watanabe, K,, et al. (2004) JCI. 114(7):898-907).

Immunocytochemistry Analysis: A representative lot of this antibody detected Vasohibin-1 (KIAA1036 protein referenced in publication) in HUVEC cells (Watanabe, K,, et al. (2004) JCI. 114(7):898-907).

The two related members of the vasohibin family, VASH1 and VASH2, encode human tubulin detyrosinases. Here we demonstrate that, in contrast to VASH1, which requires binding of small vasohibin binding protein (SVBP), VASH2 has autonomous tubulin detyrosinating activity. Moreover, we
