Noradrenaline inhibits exocytosis via G{beta}{gamma} and refilling of the readily releasable granule pool via G{alpha}i-1/2.
Hormonal inhibition of endocytosis: Novel roles for noradrenaline and Gz.
Both G i and G o heterotrimeric G proteins are required to exert the full effect of norepinephrine on the beta-cell K ATP channel.
The inhibitors of protein acylation, cerulenin and tunicamycin, increase voltage-dependent Ca(2+) currents in the insulin-secreting INS 832/13 cell.
Inhibitory role of Src family tyrosine kinases on Ca2+-dependent insulin release.
Inhibition of insulin secretion by cerulenin might be due to impaired glucose metabolism.
Stimulation of insulin release by glucose is associated with an increase in the number of docked granules in the beta-cells of rat pancreatic islets.
Massive augmentation of stimulated insulin secretion induced by fatty acid-free BSA in rat pancreatic islets.
Anaplerotic input is sufficient to induce time-dependent potentiation of insulin release in rat pancreatic islets.
Hypothesis: one rate-limiting step controls the magnitude of both phases of glucose-stimulated insulin secretion.
