The effect of platelet pretreatment with moderate amounts of 1,2-dioctanoylglycerol on subsequent thrombin-induced activation and its correlation with the degree of protein phosphorylation is studied. Protein kinase C preactivation (treatment with 1 microM dioctanoylglycerol for 20 min) significantly reduces thrombin-promoted platelet aggregation, cytosolic calcium-rise, ATP-secretion and, albeit to a lesser extent, protein phosphorylation. Exposure of platelets to dioctanoylglycerol brings about a transient phosphorylation of a 47 kDa protein and a slight but more persistent phosphorylation of proteins of approximate molecular mass 26 and 68 kDa. It is hypothesized that the latter phosphoproteins are responsible for the inhibition of the thrombin-promoted platelet activation. Agonist-evoked aggregation is more affected by a long (20 min) rather than a short (1 min) pretreatment with dioctanoylglycerol, showing no correlation with the phosphorylation of the major substrates of protein kinase C.
