title: Hypoglycemic action of chicken meat extract in type-2 diabetic KKAy mice and GK rats.
abstract: This study researched the effects of chicken meat extract on blood glucose and insulin level, membrane glucose transporter-4 (GLUT4), and tyrosine phosphorylation of insulin receptor substrate-1 (IRS-1) in type 2 diabetic KKAy mice and GK rats. Eight-week-old KKAy mice and GK rats and euglycemic control animals, C57BL/6J mice and Wistar rats, were orally administered a liquid commercial chicken meat extract, BRAND'S Essence of Chicken (BEC), for up to 8 weeks. BEC (1.5 ml/kg) had no effect on blood insulin levels, but significantly lessened the hyperglycemia in the diabetic animals. In the BEC-treated diabetic animals, insulin induced a significant increase in plasma membrane GLUT4 and cytosolic tyrosine-phosphorylated IRS-1, indicating that it attenuates insulin resistance. The present findings are the first demonstration of the hypoglycemic action of a dietary protein, and they lend credence to the reported benefits of using chicken meat as a source of protein in the dietary management of diabetic individuals.
