Increased vascular permeability is an inciting event in many vascular complications including diabetic retinopathy. We have previously reported that pigment epithelium-derived factor (PEDF) is able to inhibit vascular endothelial growth factor (VEGF)-induced angiogenesis through a novel γ-secretase-dependent pathway. In this study, we asked whether inhibition of VEGF-induced permeability by PED...
OBJECTIVES To clarify molecular mechanisms involved in the action of pigment epithelium-derived factor (PEDF) in hormone insensitive prostate cancer cells. METHODS Total ribonucleic acid from untreated and PEDF-treated cells was subjected to microarray analysis using BioStar 8464 microarray. Real-time polymerase chain reaction analysis was conducted to confirm the microarray data. RESULTS T...
BACKGROUND Pigment epithelium-derived factor (PEDF), a serine protease inhibitor, regulates extracellular matrix production in the kidney. We sought the association between urinary PEDF (uPEDF) and development of nephropathy among patients with type 2 diabetes (T2DM). METHODS Two human studies were performed in which uPEDF was determined by ELISA. These studies included (1) a cross-sectional ...
Aim Pigment epithelium-derived factor (PEDF) is a multifunctional inhibitor on both angiogenesis and tumor growth and has not been studied yet in bladder cancer. We therefore investigated the therapeutic effects of PEDF on bladder cancer in vitro and in vivo. Methods Exogenous PEDF cDNA was delivered into T24 bladder cancer cells with recombinant adenovirus vector (AdvPEDF). Virus without targe...
Purpose. To investigate the correlation between aqueous and serum levels of pigment epithelium-derived factor (PEDF) and macular choroidal thickness in high myopia patients, both with and without choroidal neovascularization (CNV). Methods. Serum and aqueous levels of PEDF were measured by enzyme-linked immunosorbent assay in 36 high myopia patients (36 eyes) with no CNV (non-CNV group), 14 hig...
Brain metastases are a significant cause of morbidity and mortality for patients with cancer, yet preventative and therapeutic options remain an unmet need. The cytokine pigment epithelium-derived factor (PEDF) is downregulated in resected human brain metastases of breast cancer compared with primary breast tumors, suggesting that restoring its expression might limit metastatic spread. Here, we...
Endothelial barrier dysfunction, which is a serious problem that occurs in various inflammatory conditions, permits extravasation of serum components into the surrounding tissues, leading to edema formation and organ failure. Pigment epithelium-derived factor (PEDF), which is a major endogenous antagonist, has been implicated in diverse biological process, but its role in endothelial barrier dy...
Age-related macular degeneration (AMD) is the leading cause of vision loss among elderly. Although the pathogenesis of AMD is associated with retinal pigmented epithelium (RPE) dysfunction and abnormal neovascularization the detailed mechanisms remain unresolved. RPE is a specialized monolayer of epithelial cells with important functions in ocular homeostasis. Pathological RPE damage contribute...
Alterations in corneal innervations result in impaired corneal sensation, severe dry eye and damage to the epithelium that may in turn lead to corneal ulcers, melting and perforation. These alterations can occur after refractive surgery. We have discovered that pigment epithelium-derived factor (PEDF) plus docosahexaenoic acid (DHA or the docosanoid bioactive neuroprotectin D1 (NPD1)) induces n...
This study assesses the association of the pigment epithelium-derived factor (PEDF) gene with age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). Publications in MEDLINE and EMBASE up to 21/08/2014 were searched for case-control association studies of PEDF with AMD and/or PCV. Reported studies giving adequate genotype and/or allele information were included. Pool...
