title: pH sensitivity of the thrombin-induced rise in fructose 2,6-bisphosphate content of human platelets.
abstract: The stimulation of human platelets with thrombin results in a rapid and sustained increase in the fructose 2,6-bisphosphate content which may play an important role in the potentiation of glycolytic flux induced by the agonist. The investigation of the effect of pH on thrombin-induced rise in platelet fructose 2,6-bisphosphate content is reported here. The results indicate that the early intracellular alkalinization which follows platelet stimulation may contribute to mediate the positive effect of thrombin on the regulatory metabolite.
