Effects fo calcium and calcium antagonist nifedipine on the glycogenolysis induced by the stimulation of alpha-and beta-adrenergic receptors in rat hepatocytes



Abstract
The effects of calcium and calcium antagonist, nifedipine on the adrenergic receptor-stimulated glycogenolysis were investigated in isolated rat hepatocytes. The hepatic glycogenolysis induced by alpha-adrenergic receptor stimulation depended on calcium ions, and betaadrenergic activation was unrelated to calcium ions. Nifedipine decreased the alpha-adrenergic agonist-induced glucose release significantly and the decrease was depended on calcium ions. The glucose release induced by beta-adrenergic agonist was not inhibited by nifedipine.
