Summary
Gastric Inhibitory Polypeptide (GIF; 1 or 10 μg/ml) potentiated glucose-induced (8 or 16.6 mM) insulin (IRI) release from isolated rat pancreatic islets. Basal release was unaffected. The threshold concentration of glucose necessary for GIF to modulate IRI release was between 6 and 8 mM. GIP had no effect on IRI release from islets submitted to a maximal glucose stimulus (25 mM).
