Platelet-derived growth factor synthesis in mesangial cells: induction by multiple peptide mitogens.
Platelet-derived growth factor (PDGF) has been implicated in several nonmalignant pathophysiological processes, including proliferative diseases of the kidney. Glomerular mesangial cells secrete a PDGF-like factor and express the PDGF A-chain and c-sis (or B-chain) mRNAs. We report here that both mRNAs are induced by serum and this effect can be mimicked by recombinant PDGF, which also markedly...
متن کاملModulatory role of platelet-derived growth factor on cytokine-induced nerve growth factor synthesis in rat glomerular mesangial cells.
Recent evidence indicates that cytokines are potent inducers of nerve growth factor (NGF) expression in peripheral tissues and in brain. Cultured rat glomerular mesangial cells respond to interleukin-1 beta (IL-1 beta) and tumour necrosis factor-alpha (TNF-alpha) by increased NGF synthesis. We found that co-stimulation of rat glomerular mesangial cells with platelet-derived growth factor (PGDF-...
متن کاملPlatelet-derived growth factor.
Platelet-derived growth factor was purified from fresh platelets by a large-scale procedure not involving the use of SDS (sodium dodecyl sulphate). The product, 0.5 mg of platelet-derived growth factor, obtained from about 3 x 1013 platelets migrated as a single component in analytical gel electrophoresis in the presence of SDS and showed no inhomogeneity on sedimentation-equilibrium analysis i...
متن کاملPlatelet-derived growth factor (PDGF) BB homodimer regulates PDGF A- and PDGF B-chain gene transcription in human mesangial cells.
Mesangial cells express platelet-derived growth factor (PDGF) A- and B-chain mRNA and release PDGF. Several polypeptide growth factors, including PDGF itself, induce PDGF A- and B- chain mRNA abundance. To understand the molecular mechanisms associated with the changes in mRNA abundance, we measured the effects of PDGF BB homodimer on PDGF A- and B-chain gene transcription in cultured mesangial...
متن کاملPlatelet-derived growth factor signaling in mesenchymal cells.
Platelet-derived growth factors (PDGFs) and their receptors are major mitogens for many cell types of mensenchymal origin, including fibroblasts and vascular smooth muscle cells (VSMCs). Their role in enhancing migratory and proliferative responses and extracellular matrix synthesis in these cells, make them key regulators of critical biological functions and in tissue diseases including tissue...
