Description:
BC3H1 myocytes release membrane-bound alkaline phosphatase to the incubation medium upon stimulation with insulin, following a time course that is consistent with the generation of dimyristoylglycerol and the appearance of a putative insulin mediator in the extracellular medium. The use of specific blocking agents shows, however, that alkaline phosphatase release and dimyristoylglycerol production are independent processes and that the blockade of either event inhibits the production of insulin mediator. These experiments suggest a new model of insulin action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Romero, G -- Luttrell, L -- Rogol, A -- Zeller, K -- Hewlett, E -- Larner, J -- AI 18000/AI/NIAID NIH HHS/ -- AM 14334/AM/NIADDK NIH HHS/ -- AM 22125/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1988 Apr 22;240(4851):509-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Virginia School of Medicine, Charlottesville 22908.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3282305" target="_blank"〉PubMed〈/a〉
