  • Title: Inhibition of PDGF BB stimulated DNA synthesis in rat aortic vascular smooth muscle cells by the expression of a truncated PDGF beta receptor.

    Journal: FEBS Lett; 1993 Dec 20; 336(1):119-23. PubMed ID: 8262192.
    Abstract:
    Rat aortic vascular smooth muscle cells (VSMCs) were transfected with a vector encoding a truncated human PDGF beta receptor or the full-length human PDGF beta receptor. Cells stably expressing the truncated human PDGF beta receptor or the full-length human PDGF beta receptor were selected and the effect of PDGF BB on DNA synthesis in these cells was studied. Cells expressing the full-length PDGF beta receptor entered DNA synthesis normally, however, cells expressing the truncated PDGF beta receptor failed to enter DNA synthesis in response to PDGF BB. These data show that the mitogenic response of rat aortic vascular smooth muscle cells to PDGF BB can be inhibited by the expression of a truncated PDGF beta receptor.
