Earlier we reported a 14-fold increase of glycogen in the brown adipose tissue (BAT) in rats when the animals were placed back from cold to neutral temperature. To elucidate the mechanism, here we compared the level of glucose transporter 4 (GLUT4) protein, uncoupling protein (UCP) 1 and UCP3 mRNA and protein expressions in the BAT under the same conditions. We found that the increased GLUT4 level in cold was maintained during the reacclimation. After 1 week cold exposure the mRNA and protein content of UCP1 increased parallel, while the protein level of UCP3 decreased, contrary to its own mRNA level.
