PEDF inhibits growth of retinoblastoma by anti-angiogenic activity

Stimulation of neovascularization by the anti-angiogenic factor PEDF.

PURPOSE Examine the effect of (pigment epithelium-derived growth factor; PEDF) on laser-induced choroidal neovascularization (CNV). METHODS Adult C57Bl/6 mice were anesthetized and four laser spots were placed in each quadrant of the fundus with a krypton red laser (614 nm, 50 microm, 0.05 second, 200 mW). Animals were treated with various doses of PEDF administered with miniosmotic pumps imp...

Crystal structure of human PEDF, a potent anti-angiogenic and neurite growth-promoting factor.

Pigment epithelium-derived factor (PEDF), a noninhibitory member of the serpin superfamily, is the most potent inhibitor of angiogenesis in the mammalian ocular compartment. It also has neurotrophic activity, both in the retina and in the central nervous system, and is highly up-regulated in young versus senescent fibroblasts. To provide a structural basis for understanding its many biological ...

Anti-angiogenic activity of auraptene

The objective of this research was to test the in vitro anti-angiogenic activity of auraptene, a coumarin from citrus peel oil. We tested the ability of auraptene to inhibit in vitro angiogenesis using vascular endothelial growth factor (VEGF)-induced human umbilical endothelial cells (HUVEC) growth stimulation. Auraptene was applied at concentrations between 0 μM and 1μM to HUVEC in the presen...

Anti-angiogenic activity of tocotrienol.

The anti-angiogenic property of vitamin E compounds, with particular emphasis on tocotrienol, has been investigated in vitro. Tocotrienol, but not tocopherol, inhibited both the proliferation and tube formation of bovine aortic endothelial cells, with delta-tocotrienol appearing the highest activity. Also, delta-tocotrienol reduced the vascular endothelial growth factor-stimulated tube formatio...
