The mRNA expressions of UCP2 and UCP3, two newly described genes with high sequence homology to the uncoupling protein UCP1 in brown adipose tissue (BAT), were examined in two skeletal muscles (gastrocnemius and soleus) as well as in interscapular BAT (IBAT) of the rat in response to food deprivation and controlled refeeding. In IBAT (a tissue highly(More)
Endurance exercise training has been shown to decrease diet-induced thermogenesis (DIT) in rats and humans. In rodents, most thermogenesis is thought to occur in brown adipose tissue via activation of the uncoupling protein-1 (UCP1) and in skeletal muscle. Since the level of UCP1 mRNA in rat BAT was reported to be unmodified by exercise training, the newly(More)
During fasting, when overall metabolism changes, the contribution of glucose and fatty acids (FA) to cardiac energy production alters as well. Here, we examined if the heart is able to adapt to such fasting-induced changes by modulation of its gene expression. Rats were fed ad libitum or fasted for 46 h, resulting in reduced circulating glucose levels and a(More)
