Pigment epithelium-derived factor (PEDF) is expressed in several normal organs and identified as an inhibitor of neovascularization. In the present study, we screened the expression of PEDF immunohistochemically and investigated its correlation with clinicopathological features in patients who underwent surgery for ductal pancreatic adenocarcinoma. Of the 80 patients, 22 cases (27.5%) were posi...
Pigment epithelium-derived factor (PEDF) plays an important role in insulin resistance (IR). The study aims to investigate the effect of rosiglitazone, an insulin sensitizer, on PEDF production and release both in vivo and in vitro. Male SD rats were divided into normal control group, high-fat group, and rosiglitazone group. Hyperinsulinemic euglycemic clamp was performed to evaluate insulin se...
BACKGROUND The role of pigment epithelium-derived factor (PEDF) in protection of coronary artery disease (CAD) remains controversial. The aim of this study was to reassess the value of PEDF in predicting the severity and prognosis of newly diagnosed stable CAD in a Chinese population. MATERIAL AND METHODS Plasma PEDF levels were measured in 259 stable CAD patients undergoing coronary angiograph...
BACKGROUND Polycystic ovary syndrome (PCOS) has been recognized as a metabolic disorder, manifested by abdominal obesity, insulin resistance, dyslipidemia and hypertension. Pigment epithelium-derived factor (PEDF), a member of the serine protease inhibitor family, is a pleiotropic protein known for its antiangiogenic, antioxidant, and neuroprotective properties and has been shown to induce insu...
Context: the role of vascular endothelial growth factor (VEGF) and pigment epithelium-derived (PEDF) on renal function diabetics is unclear.
 Objective: This study investigated relationship between VEGF, PEDF urea, creatinine estimated glomerular filtration rate (eGFR) in type 2 diabetics.
 Materials Methods: 100 50 controls were recruited into this case-control study. Analytes determ...
PURPOSE To compare a 44-mer pigment epithelial-derived factor (PEDF) peptide with neurotrophic activity, and a 34-mer PEDF with antiangiogenic properties in association with docosahexaenoic acid (DHA) in corneal nerve regeneration after experimental surgery. METHODS A corneal stromal dissection was performed in rabbits. Treatment groups received topical 44-mer, 34-mer, or full PEDF plus DHA. ...
Here, role(s) of pigment epithelial-derived factor (PEDF) and glial-derived neurotrophic factor (GDNF) on photoreceptor development in three-dimensional reaggregates from the retinae of the E6 chick embryo (rosetted spheroids) was investigated. Fully dispersed cells were reaggregated under serum-reduced conditions and supplemented with 50 ng/ml PEDF alone or in combination with 50 ng/ml GDNF. T...
BACKGROUND Pigment epithelial-derived factor (PEDF) displays its antiangiogenicity by mechanisms partly involving suppression of the cellular FADD-like IL-1β-converting enzyme (FLICE)/caspase-8-inhibitory protein (c-FLIP) expression in endothelial cells. c-Jun NH(2)-terminal kinases (JNKs) regulate c-FLIP expression in endothelial cells. The effect of PEDF on other cells remains unclear. MATE...
BACKGROUND Angiogenesis plays an important role in tumor growth, invasion, and eventually metastasis. Antiangiogenic strategies have been proven to be a promising approach for clinical therapy for a variety of tumors. As a potent inhibitor of tumor angiogenesis, pigment epithelium-derived factor (PEDF) has recently been studied and used as an anticancer agent in several tumor models. METHODS ...
Pathological retinal neovascularization and choroidal neovascularization are major causes of vision loss in a variety of clinical conditions, such as retinopathy of prematurity, age-related macular degeneration, and diabetic retinopathy. Pigment epithelial-derived factor (PEDF) has been found to be the most potent natural, endogenous inhibitor of neovascularization, but its application is restr...
