Brief Summary:
The purpose of this study is to determine whether the level of FOXA2 expression in fat tissue is a biomarker of insulin resistance. To test this hypothesis, we will perform euglycemic-hyperinsulinemic clamps in normal and obese human subjects to calculate insulin sensitivity, and see if insulin sensitivity correlates with the FOXA2 expression in subcutaneous fat.
Detailed Description:
The investigators at Rockefeller University Hospital are engaged in research on the nature, diagnosis and treatment of obesity and diabetes. The investigators are trying to find out why insulin, a blood sugar lowering hormone that is released by the pancreas following a meal, does not work effectively in individuals with obesity or type 2 diabetes. The investigators have recently discovered a protein in fat cells of obese mice that helps fat cells to take up and break down sugar from the blood. This protein (called FOXA2) also prevents the generation of more fat cells. FOXA2 is only present in obese mice, but absent from fat stores of lean animals. Insulin can stimulate the production of FOXA2 in fat cells. Furthermore, the levels of FOXA2 protein correlate with the degree of blood insulin levels. In this study, we are would like to determine whether FOXA2 is also produced in fat cells of humans, and if its level correlates with the degree of obesity and insulin resistance.
