Introduction Type 2 diabetes mellitus is a complex, multisystem disease with a pathophysiology that includes defects in insulin-stimulated peripheral glucose disposal and an impaired suppression of hepatic glucose production ( Matthaei et al . 2000

Introduction It is well established that insulin has direct and indirect inhibitory effects on glucose production (GP). The direct effect is due to interaction of hepatic sinusoidal insulin with the hepatocyte insulin receptor

Introduction The global prevalence of obesity and type 2 diabetes mellitus (T2DM) is increasing. These two diseases are associated with insulin resistance (IR) and disrupted lipid and glucose metabolism ( Saltiel & Kahn 2001 ). To understand

Introduction Impaired insulin-stimulated glucose disposal into skeletal muscle is a major component of the insulin resistance (IR) that develops in advance of type 2 diabetes (T2D) ( DeFronzo & Tripathy 2009 ). In addition, obesity and IR commonly

Introduction Glucagon is a 29-amino acid polypeptide secreted by the α or glucagon cell of the islet of Langerhans in response to hypoglycemia, arginine, gastric inhibitory polypeptide (during ambient reduced glucose levels), gastrin, and potassium
