Pigment epithelium-derived factor: clinical significance in estrogen-dependent tissues and its potential in cancer therapy
Pigment epithelium-derived factor (PEDF) is a glycoprotein that belongs to the family of non-inhibitory serpins. The broad spectrum of PEDF biological activity is evident when considering its effects in promoting cell survival and proliferation, as well as its antiangiogenic, antitumor, and anti-metastatic properties. Although the structural domains of the PEDF gene that mediate such diverse ef...
متن کاملPigment epithelium-derived factor decreases outflow facility.
PURPOSE Pigment epithelium-derived factor (PEDF) regulates blood-retinal barrier function. As a constituent of aqueous humor, the role of PEDF in conventional outflow function is unknown. The goals of the study were to examine the effects of PEDF on barrier function of cultured Schlemm's canal (SC) endothelia and outflow facility in mouse eyes in situ. METHODS To model the inner wall of SC, t...
متن کاملPigment Epithelium-derived Factor (PEDF) Prevents Retinal Cell Death via Pigment Epithelium- derived Factor-R (PEDF-R): Identification of a Functional Ligand Binding Site*
Background: PEDF has neurotrophic activity and interacts with PEDF-R, a membrane-linked lipase. Results: A PEDF-binding region of PEDF-R is required for PEDF-R enzymatic stimulation and peptides derived from this region block PEDF/PEDF-R-mediated retinal survival activities. Conclusions: A ligand binding domain is identified in PEDF-R, a critical receptor for PEDF’s survival activity. Significa...
متن کاملExpression of pigment epithelium-derived factor in experimental choroidal neovascularization.
PURPOSE To investigate the expression of pigment epithelium-derived factor (PEDF) in the rat laser-injury model of choroidal neovascularization (CNV). METHODS Retinas were immunostained for PEDF at different times (1, 2, and 3 weeks) after laser injury. Levels of PEDF protein in the vitreous at 1, 3, 7, 14, and 28 days after laser injury were also assayed by Western blot. RESULTS Protein le...
متن کاملPigment epithelium-derived factor promotes neurite outgrowth of retinal cells.
The ability of pigment epithelium-derived factor (PEDF) to promote neurite outgrowth of retinal cells through mitogen-activated protein kinase (MAPK) pathways was examined. Neurite outgrowth effects of PEDF were determined by quantifying the neurite length extending from cultured chick embryo retinal explants, and neurite outgrowth ratio of R28 cells (a neural cell line derived from the neonata...
