title: Effects of vanadate and insulin on glucose 1,6-P2 and fructose 2,6-P2 levels in rat skeletal muscle.
abstract: Levels of glucose 1,6-P2 but not fructose 2,6-P2 were found decreased in skeletal muscle of alloxan-diabetic ketotic rats. Administration of both insulin and vanadate restored the altered values without affecting fructose 2,6-P2 concentrations. In normal rats, insulin increased muscle levels of both sugars, and vanadate decreased glucose 1,6-P2 without changing fructose 2,6-P2 levels. Enzymatic activities involved in glucose 1,6-P2 and fructose 2,6-P2 metabolism were not affected under any experimental condition.
