Abstract: | In pancreatic islets removed from rats fasted for 48 hours, the insulin secretory response to glucose is decreased. Although the activity of phosphoglucomutase is unaffected by fasting, the decrease in glucose-stimulated insulin release coincides with a suppression of the glucose-induced increment in both glucose-1,6-P2 content and lactate or pyruvate output. These findings are compatible with a regulatory role of glucose-1,6-P2 in the control of glycolysis in pancreatic islets. |
