Platelet-derived growth factor signaling and human cancer.
Platelet-derived growth factor (PDGF) is a critical regulator of mesenchymal cell migration and proliferation. The vital functions of PDGFs for angiogenesis, as well as development of kidney, brain, cardiovascular system and pulmonary alveoli during embryogenesis, have been well demonstrated by gene knock-out approaches. Clinical studies reveal that aberrant expression of PDGF and its receptor ...
متن کاملPlatelet-derived growth factor signaling in human malignancies
Platelet-derived growth factors (PDGFs) and their receptors were identified and purified decades ago. PDGFs are important during normal development and in human cancers. In particular, autocrine PDGF signaling has been implicated in various types of malignancies such as gliomas and leukemia. In contrast, paracrine signaling was found in cancers that originate from epithelial cells, where it may...
متن کاملPlatelet-derived growth factor in human glioma.
Platelet-derived growth factor (PDGF) is a 30 kDa protein consisting of disulfide-bonded dimers of A- and B-chains. PDGF receptors are of two types, alpha- and beta-receptors, which are members of the protein-tyrosine kinase family of receptors. The receptors are activated by ligand-induced dimerization, whereby the receptors become phosphorylated on tyrosine residues. These form attachment sit...
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 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...
