Lack of hepatic “interregulation” during inhibition of glycogenolysis in a canine model

It has been proposed that the glycogenolytic and gluconeogenic pathways contributing to endogenous glucose production are interrelated. Thus a change in one source of glucose 6-phosphate might be compensated for by an inverse change in the other pathway. We therefore investigated the effects of 1,4-dideoxy-1,4-imino-d-arabinitol (DAB), a potent glycogen phosphorylase inhibitor, on glucose production in fasted conscious dogs. When dogs were...
