    The fms-like tyrosine kinase, a receptor for vascular endothelial growth factor (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-02-21
    Description: The fms-like tyrosine kinase (Flt) is a transmembrane receptor in the tyrosine kinase family. Expression of flt complementary DNA in COS cells conferred specific, high-affinity binding of vascular endothelial growth factor, also known as vascular permeability factor (VEGF-VPF), a factor that induces vascular permeability when injected in the guinea pig skin and stimulates endothelial cell proliferation. Expression of Flt in Xenopus laevis oocytes caused the oocytes to release calcium in response to VEGF-VPF. These findings show that flt encodes a receptor for VEGF-VPF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Vries, C -- Escobedo, J A -- Ueno, H -- Houck, K -- Ferrara, N -- Williams, L T -- P01 HL-43821/HL/NHLBI NIH HHS/ -- R01 HL-32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1992 Feb 21;255(5047):989-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1312256" target="_blank"〉PubMed〈/a〉

    Role of phosphatidylinositol kinase in PDGF receptor signal transduction (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-03
    Description: The molecules with which the platelet-derived growth factor (PDGF) receptor interacts to elicit the biochemical reactions responsible for cell proliferation have not been identified. Antisera directed against specific PDGF receptor peptides coprecipitated a phosphatidylinositol (PI) kinase and the PDGF receptor. Immunoprecipitates from PDGF-stimulated cells contained 10 to 50 times as much PI kinase as those from unstimulated cells. Mutation of the PDGF receptor by deletion of its kinase insert region resulted in a receptor markedly less effective than the wild type in eliciting cell proliferation and defective in PDGF-stimulated PI kinase, but still capable of PDGF-induced receptor autophosphorylation and phosphoinositide hydrolysis. These data show that the PDGF receptor is physically associated with a PDGF-sensitive PI kinase that is distinct from tyrosine kinase and is not required for PDGF-induced PI hydrolysis. The finding that the mutant PDGF receptor missing the kinase insert domain elicited known early biochemical responses to PDGF, but did not associate with or regulate PI kinase, suggests a novel role for the receptor-associated PI kinase in the transmission of mitogenic signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coughlin, S R -- Escobedo, J A -- Williams, L T -- HL 32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1191-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2466336" target="_blank"〉PubMed〈/a〉

    A common PDGF receptor is activated by homodimeric A and B forms of PDGF (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-06-10
    Description: The human platelet-derived growth factor (PDGF) receptor complementary DNA was cloned and expressed by transfection of Chinese hamster ovary (CHO) fibroblasts. The ability of CHO cells expressing the human receptor complementary DNA (CHO-HR5) to interact with different recombinant forms of PDGF (AA and BB homodimers) was tested. Both forms of PDGF bind to the transfected receptor, stimulate the receptor tyrosine kinase activity, and elicit a mitogenic response in a manner that was indistinguishable from the responses of Balb/c 3T3 cells to AA and BB forms of PDGF can be attributed to a single type of receptor and show that the AA form, like the BB form, is a true mitogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Escobedo, J A -- Navankasatussas, S -- Cousens, L S -- Coughlin, S R -- Bell, G I -- Williams, L T -- HL-32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1988 Jun 10;240(4858):1532-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, San Francisco.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2836953" target="_blank"〉PubMed〈/a〉
