Thiazolidinediones (TZDs) are a novel class of insulin-sensitizing agents used in the treatment of NIDDM and are potent agonists for the nuclear hormone receptor peroxisome proliferator-activated receptor gamma (PPARgamma). The thiazolidinedione BRL 49653 has been shown to promote the differentiation of the HIB-1B brown preadipocyte cell line and to increase rat interscapular brown adipose tissue (BAT) mass. Given the importance of brown fat in the control of energy metabolism in rodents, this may represent an important therapeutic effect of this class of compound. To date, however, no studies examining the effects of TZDs on human brown fat have been reported. In the present study, we have ..View full abstract
