概要
The platelet-derived growth factor (PDGF) family has five heparin-binding members that assemble into four homodimers (PDGF-AA, PDGF-BB, PDGF-CC, and PDGF-DD) and one heterodimer (PDGF-AB; Li & Eriksson). PDGF signals through the receptor tyrosine kinases PDGFRα and PDGFRβ. It has been shown that PDGF-induced migration involves signaling pathways involving MEK/ERK, EGFR, Src and PI3K/AKT (Kim et al.). PDGF is a potent mitogen for cells of mesenchymal origin such as fibroblasts and vascular smooth muscle cells. PDGF has been implicated in pathogenesis of atherosclerosis, glomerulonephritis, cancer, and in the contraction of vascular smooth muscle cells of rat aortic tissues (Fretto et al.; Sachinidis et al.). PDGF-CC is secreted as a latent growth factor and requires activation by proteolytic processing (Li & Eriksson). PDGF-CC binds to PDGFRα homodimers and PDGFRαβ heterodimers, but not to PDGFRβ homodimers (Li & Eriksson). PDGF-CC is an angiogenic factor that stimulates coronary artery smooth muscle cell proliferation and plays a role in cardiovascular development (Gilbertson et al.). PDGF-CC is also expressed in many tumors and plays a role in tumorigenesis (Zwerner & May).

Data
(A) The biological activity of Human Recombinant PDGF-CC was tested by its ability to promote the proliferation of 3T3 cells. Cell proliferation was measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the example above is less than 1 ng/mL. (B) 5 μg of Human Recombinant PDGF-CC was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant PDGF-CC has a predicted molecular mass of 12.5 kDa.
