PURPOSE Bone morphogenetic proteins (BMPs) are multi-functional cytokines that have wide ranging effects on a variety of cells and tissues. In the present study, we profile the expression of BMPs, BMP receptors, and BMP associated proteins in the human trabecular meshwork (TM) and optic nerve head (ONH), two tissues involved in glaucoma pathogenesis. METHODS Total RNA was isolated and subject...
BACKGROUND Mutations in the bmpr2 gene, encoding the type II bone morphogenetic protein (BMP) receptor, have been identified in patients with pulmonary arterial hypertension (PAH), implicating BMP signaling in PAH. The aim of this study was to assess BMP signaling and its physiological effects in a monocrotaline (MCT) model of PAH. METHODS AND RESULTS Expression of BMP receptors Ib and II, an...
The importance of morphogenetic proteins (BMPs) and their antagonists in vascular development is increasingly being recognized. BMP-4 is essential for angiogenesis and is antagonized by matrix Gla protein (MGP) and crossveinless 2 (CV2), both induced by the activin receptor like-kinase 1 (ALK1) when stimulated by BMP-9. In this study, however, we show that CV2 preferentially binds and inhibits ...
BACKGROUND Bone Morphogenetic Protein (BMP) signaling pathways are involved in differentiation of stem cells into diverse cell types, and thus BMPs can be used as main guidance molecules for in vitro differentiation of human stem cells. METHODOLOGY/PRINCIPAL FINDINGS We have analyzed the ability for inducing differentiation of the heterodimer BMP-2/BMP-6 (BMP-2/6) compared to the homodimers B...
BACKGROUND Transcutaneous in vivo electroporation is expected to be an effective gene-transfer method for promoting bone regeneration using the BMP-2 plasmid vector. To promote enhanced osteoinduction using this method, we simultaneously transferred cDNAs for BMP-2 and BMP-7, as inserts in the non-viral vector pCAGGS. METHODS First, an in vitro study was carried out to confirm the expression ...
Prostate cancer frequently metastasizes to bone where it forms osteoblastic lesions through unknown mechanisms. Bone morphogenetic proteins (BMP) are mediators of skeletal formation. Prostate cancer produces a variety of BMPs, including BMP-6. We tested the hypothesis that BMP-6 contributes to prostate cancer-induced osteosclerosis at bone metastatic sites. Prostate cancer cells and clinical ti...
Introduction To induce sufficient new bone formation, high doses of bone morphogenetic protein-2 (BMP-2) are applied in regenerative medicine that often induce serious side effects. Therefore, improved treatment strategies are required. Here, we investigate whether the delivery of BMP-2 lyophilized in the presence of trehalose reduced the dose of BMP-2 required for bone regeneration. Material...
در این رساله، ارتباط مدیریت جانشین پروری بر گرایش های کارراهه کارکنان سازمان مورد بررسی قرار گرفته است. نظام مدیریت جانشین پروری از دو دیدگاه استراتژیک و عملیاتی مورد بررسی قرار گرفته است: دیدگاه استراتژیک تناسب فرآیند جانشین پروری را با استراتژی سازمان، ساختار سازمانی و علائق کارراهه کارکنان مورد بررسی قرار می دهد و دیدگاه عملیاتی گستردگی و جامع بودن فعالیتهای مدیریت جانشین پروری در سازمان را ...
با توجه به دیدگاه های مرسوم در روش های رسوبزدایی در سدها مبتنی بر دیدگاه عمرطراحی(دوره زمانی معین) و عدم بررسی عملکردی درطی طول عمر مخزن (فقدان فرآیند مدیریت رسوب) در جوامع درحال توسعه، در این تحقیق به نگرشی مدیریتی و تصمیم ساز در رسوبزدایی مخازن پرداخته شده است. دراین راستا، استراتژی های کنترل منابع رسوب و فرسایش در مدیریت حوضه به منظور کاهش جریان های رسوبی با ساماندهی بالادست رودخانه در سطح ...
2,2-Bis(bromomethyl)-1,3-propanediol (BMP) is a brominated flame retardant used in unsaturated polyester resins. In a 2-year bioassay BMP was shown to be a multisite carcinogen in rats and mice. Because glucuronidation is the key metabolic transformation of BMP by rats, in this study the in vitro hepatic glucuronidation of BMP was compared across several species. In addition, the glucuronidatio...
