Platelet-derived growth factor (PDGF)-BB has been shown previously to increase glycosaminoglycan (GAG) synthesis but not DNA synthesis in freshly isolated fetal lung fibroblasts. In the present study, we found that PDGF-BB also enhanced35SO4incorporation into the small, soluble proteoglycan biglycan without affecting biglycan's core protein mRNA expression, suggesting that PDGF-BB mainly affect...
Kidney glomerulus mesangial cells fail to develop in mice carrying targeted null mutations in the platelet-derived growth factor (PDGF)-B or PDGF-Rbeta genes. We have examined the pattern of expression of these genes and smooth muscle markers during kidney development, to address the possible mechanisms underlying the mutant phenotypes. In wild-type embryos, PDGF-B was expressed in vascular end...
Platelet-derived growth factor (PDGF)-D is a PDGF receptor β (PDGFRβ)-specific ligand implicated in a number of pathological conditions, such as cardiovascular disease and cancer, but its biological function remains incompletely understood. In this study, we demonstrate that PDGF-D binds directly to neuropilin 1 (NRP1), in a manner that requires the PDGF-D C-terminal Arg residue. Stimulation wi...
Platelet-derived growth factor (PDGF)-BB is a well-known smooth muscle (SM) cell (SMC) phenotypic modulator that signals by binding to PDGF alphaalpha-, alphabeta-, and betabeta-membrane receptors. PDGF-DD is a recently identified PDGF family member, and its role in SMC phenotypic modulation is unknown. Here we demonstrate that PDGF-DD inhibited expression of multiple SMC genes, including SM al...
هدف: هدف از تحقیق حاضر تعیین اثر شش هفته تمرین استقامتی و مصرف مکمل جینسینگ بر فاکتور رشد اندوتلیال عروق (vascular endothelial growth factor, vegf) و فاکتور رشد مشتق از پلاکت (platelet-derived growth factor, pdgf) سرم دانشجویان زن تمرین نکرده بود. مواد و روش ها: در این تحقیق 32 دانشجوی زن غیرورزشکار از دانشگاه گرگان با میانگین سنی 2±20 به صورت تصادفی به چهار گروه تمرین استقامتی، تمرین استقامت...
BACKGROUND AND PURPOSE The level of platelet-derived growth factor (PDGF) in cerebrospinal fluid is elevated in subarachnoid hemorrhage (SAH). Therefore, the contractile effect of PDGF on the basilar artery was examined in SAH. METHODS A rabbit double-hemorrhage SAH model was used. In the medial layers of the control basilar artery, PDGF had no effect on contraction up to 1 nmol/L, whereas 3 ...
Platelet-derived growth factor (PDGF) is a potent activator for cells of mesenchymal origin. PDGF stimulates chemotaxis, proliferation, and new gene expression in monocytes-macrophages and fibroblasts in vitro, cell types considered essential for tissue repair. Therefore, we analyzed the influence of exogenously administered recombinant B chain homodimers of PDGF (PDGF-BB) on two experimental t...
Exposure of BALB/c-3T3 cells (clone A31) to platelet-derived growth factor (PDGF) results in a rapid time- and dose-dependent alteration in the distribution of vinculin and actin. PDGF treatment (6-50 ng/ml) causes vinculin to disappear from adhesion plaques (within 2.5 min after PDGF exposure) and is followed by an accumulation of vinculin in punctate spots in the perinuclear region of the cel...
Coxsackievirus B3 (CVB3) is the most common causative agent of myocarditis. Acute myocarditis caused by CVB3 infection either recovers completely without any functional and morphological defects or progresses to chronic myocarditis, which is characterized by chronic inflammation and interstitial hyperplasia that may be related to progressive intrinsic dysfunction, degeneration, and loss of card...
The angiogenic mechanism and therapeutic potential of PDGF-CC, a recently discovered member of the VEGF/PDGF superfamily, remain incompletely characterized. Here we report that PDGF-CC mobilized endothelial progenitor cells in ischemic conditions; induced differentiation of bone marrow cells into ECs; and stimulated migration of ECs. Furthermore, PDGF-CC induced the differentiation of bone marr...
