Differential Regulation of Adiponectin Secretion from Cultured Human Omental and Subcutaneous Adipocytes: Effects of Insulin and Rosiglitazone

Adiponectin is an adipocyte-derived plasma protein with insulin-sensitizing and antiatherosclerotic properties. Because adipose tissue depots differ in the strength of their association with the adverse metabolic consequences of obesity, we studied the secretion of adiponectin in vitro from paired samples of isolated human omental and sc adipocytes and its regulation by insulin and rosiglitazone. Cells were incubated for 12 or 24 h with and...
