Glucagon is the physiological antagonist of insulin. Postprandial (pp) hyperglycemia in impaired glucose tolerance (IGT) and in type 2 diabetes mellitus (T2DM) may also depend on irregularities in glucagon secretion. This study investigated the glucagon excursion after a lipid-glucose-protein tolerance test in subjects with different stages of glucose intolerance.

This polymorphism has been associated with high insulin sensitivity and low body weight, but no data have been published to date about its effect on early atherosclerosis. We investigated the relationship of the Pro(12)Ala polymorphism to early atherosclerosis, measured by the intima-media thickness (IMT).
