Cancer is becoming an increasingly common disease in which abnormal cells aggressively grow, invade, and metastasize. In this paper, we review the biological functions of PEDF (pigmented epithelium-derived factor) against cancer, with a focus on a particular type of bone cancer called osteosarcoma. PEDF is a 50 kDa glycoprotein and is a potent inhibitor of angiogenesis, via its ability to decre...
We show that pigment epithelium-derived factor (PEDF), which is secreted from primary or iPSC-derived retinal pigment epithelium (RPE), dramatically inhibits the growth of iPSCs. PEDF is detected abundantly in culture supernatants of primary or iPSC-derived RPE. Apoptotic cell death is induced in iPSC when co-cultured with RPE, a process that is significantly blocked by addition of antibody aga...
Human melanoma mortality is associated with the growth of metastasis in selected organs including the lungs, liver, and brain. In this study, we examined the consequences of overexpression of pigment epithelium-derived factor (PEDF), a neurotrophic factor and potent angiogenesis inhibitor, on both melanoma primary tumor growth and metastasis development. PEDF overexpression by melanoma cells gr...
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...
Pigment epithelium-derived factor (PEDF) is a broadly expressed multifunctional member of the serine proteinase inhibitor (serpin) family. This widely studied protein plays critical roles in many physiological and pathophysiological processes, including neuroprotection, angiogenesis, fibrogenesis and inflammation. The present review summarizes the temporal and spatial distribution patterns of P...
This study investigated whether vascular endothelial growth factor (VEGF), soluble intercellular adhesion molecule-1 (sICAM-1), and pigment epithelium-derived factor (PEDF) influence the visual prognosis of patients with macular edema and branch retinal vein occlusion (BRVO). In 47 consecutive patients (47 eyes) undergoing vitrectomy, retinal thickness was examined by optical coherence tomograp...
bstract—Pigment epithelium-derived factor (PEDF) protects mmature cerebellar granule cell neurons (CGCs) against apotosis induced by K and serum deprivation. However, the recise mechanism of this protection remains unknown. We ecently reported that the transcription factor nuclear factor appa B (NFB) is activated in PEDF-treated CGCs. Although it s well known that NFB blocks apoptotic cell deat...
Pigment epithelium-derived factor (PEDF) protects immature cerebellar granule cells (1-3 days in vitro) against induced apoptosis and mature cells (5+ days in vitro) against glutamate toxicity, but its precise mechanism is still unknown. Because the transcription factor NFkappaB blocks cell death, including neuronal apoptosis, we have investigated the ability of PEDF to exert its effects via NF...
PEDF is a secreted glycoprotein that is widely expressed by multiple organs. Numerous functional contributions have been attributed to PEDF with antiangiogenic, antitumor, anti-inflammatory, and neurotrophic properties among the most prominent. The discovery that null mutations in the PEDF gene results in Osteogenesis Imperfecta Type VI, a rare autosomal recessive bone disease characterized by ...
