title: 1-Oleoyl-2-acetyl-glycerol (OAG) stimulates the formation of phosphatidylinositol 4-phosphate in intact human platelets.
abstract: Diacylglycerol (DAG) is one of the primary products formed upon activation of platelets with stimuli that induce inositol lipid turnover. Its synthetic analog, 1-oleoyl-2-acetyl-glycerol (OAG) is often used as a tool for studying the involvement of the lipid in platelet activation. We found that OAG induces a concomitant increase in [32P]-incorporation in phosphatidylinositol 4-phosphate (PIP) and in the 40K protein, the endogenous substrate for protein kinase C in human platelets. It is hypothesized that in receptor mediated platelet activation a metabolic link might exist between both processes.
