Mechanism of thrombin-induced rise in platelet fructose 2,6-bisphosphate content. Studies using phorbol myristate acetate, dioctanoylglycerol and ionophore A23187.


ABSTRACT: The mechanism by which thrombin increases platelet fructose 2,6-bisphosphate content was investigated. The action of thrombin was mimicked by phorbol 12 myristate 13-acetate and 1,2-dioctanoylglycerol. Ca2+ with A23187 potentiated the action of both these compounds. The action of thrombin required mobilization of intracellular and extracellular Ca2+ and was not decreased by indomethacin. This study suggests that protein kinase C activation and Ca2+ mobilization are both involved in the activation of glycolysis by thrombin.
