The Role of PEDF in Bone Mineralization

چکیده

BACKGROUND: Osteogenesis imperfecta (OI) type VI is a heritable disease that leads to a large number of fractures in children. It is caused by genetic mutations that lead to the absence of pigmentepithelium derived factor (PEDF) in all body cells. PEDF is a protein that is produced and secreted by cells in many tissues (liver, eye, fat). In bone, it is particularly highly expressed in osteoblasts, the bone-forming cells. The function of PEDF in these cells is not known at present. It is clear, however, that PEDF deficiency results in OI type VI.

Pigment epithelium-derived factor (PEDF) normalizes matrix defects in iPSCs derived from Osteogenesis imperfecta Type VI

Osteogenesis imperfecta (OI) Type VI is characterized by a defect in bone mineralization, which results in multiple fractures early in life. Null mutations in the PEDF gene, Serpinf1, are the cause of OI VI. Whether PEDF restoration in a murine model of OI Type VI could improve bone mass and function was previously unknown. In Belinsky et al, we provided evidence that PEDF delivery enhanced bon...

Lack of circulating pigment epithelium-derived factor is a marker of osteogenesis imperfecta type VI.

BACKGROUND Osteogenesis imperfecta (OI) type VI is a rare autosomal recessive bone fragility disorder that is caused by inactivating mutations in SERPINF1, the gene that encodes pigment-epithelium derived factor (PEDF). Determining PEDF serum levels might facilitate the diagnosis of OI type VI. OBJECTIVE The objective of the study was to assess whether lack of circulating PEDF is a specific m...

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...

The Effects of Dietary Valine on Performance, SerumAntibody Titre and Bone Mineralization in Broiler Chicks

The present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to Newcastle disease virus vaccination and bone mineralization. The experiment was conducted using 300 Ross 308 male broilers. One-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 2...

Neural Stem Cell-based Intraocular Administration of Pigment Epithelium-derived Factor Promotes Retinal Ganglion Cell Survival and Axon Regeneration after Optic Nerve Crush Injury in Rat: An Experimental Study

Background: Pigment epithelium-derived factor (PEDF) is regarded as a multifunctional protein possessing neurotrophic and neuroprotective properties. PEDF has a very short half-life, and it would require multiple injections to maintain a therapeutically relevant level without a delivery system. However, multiple injections are prone to cause local damage or infection. To overcome this, we chose...
