Conversion of glutamate into proline by the leucine analog BCH enhances biphasic insulin secretion in pancreatic β-cells
Biphasic insulin secretion, which fails in type 2 diabetes, can be provoked by various nutrient stimuli, glucose being the superior physiological one. To identify pathways that may play a role in β-cell stimulus-secretion coupling, we compared β-cell and islet functional, secretory, and metabolic responses to glucose and 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid (BCH), a leucine analog, tha
