We have examined whether GLUT-10 and GLUT-12, members of the Class III group of the recently expanded family of facilitative glucose transporters, are expressed in adipose tissues. The mouse GLUT-12 gene, located on chromosome 10, comprises at least five exons and encodes a 622 amino acid protein exhibiting 83% sequence identity and 91% sequence similarity to human GLUT-12. Expression of the GLUT-12 gene was evident in all the major mouse adipose tissue depots (epididymal, perirenal, mesenteric, omental, and subcutaneous white; interscapular brown). The GLUT-10 gene is also expressed in mouse adipose tissues and as with GLUT-12 expression occurred in the mature adipocytes as well as the stromal vascular cells. 3T3-L1 adipocytes express GLUT-10, but not GLUT-12, and expression of GLUT-12 was not induced by insulin or glucose. Both GLUT-10 and GLUT-12 expression was also found in human adipose tissue (subcutaneous and omental) and SGBS adipocytes. It is concluded that white fat expresses a wide range of facilitative glucose transporters.

Resveratrol has been reported to increase adrenaline-induced lipolysis in 3T3-L1 adipocytes. The general aim of the present work was to gain more insight concerning the effects of trans-resveratrol on lipid mobilization. The specific purpose was to assess the involvement of the two main lipases: adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL), in the activation of lipolysis induced by this molecule. For lipolysis experiments, 3T3-L1 and human SGBS adipocytes as well as adipose tissue from wild-type, ATGL knockout and HSL knockout mice were used. Moreover, gene and protein expressions of these lipases were analyzed. Resveratrol-induced free fatty acids release but not glycerol release in 3T3-L1 under basal and isoproterenol-stimulating conditions and under isoproterenol-stimulating conditions in SGBS adipocytes. When HSL was blocked by compound 76-0079, free fatty acid release was still induced by resveratrol. By contrast, in the presence of the compound C, an inhibitor of adenosine monophosphate-activated protein kinase, resveratrol effect was totally blunted. Resveratrol increased ATGL gene and protein expressions, an effect that was not observed for HSL. Resveratrol increased fatty acids release in epididymal adipose tissue from wild-type and HSL knockout mice but not in that adipose tissue from ATGL knockout mice. Taking as a whole, the present results provide novel evidence that resveratrol regulates lipolytic activity in human and murine adipocytes, as well as in white adipose tissue from mice, acting mainly on ATGL at transcriptional and posttranscriptional levels. Enzyme activation seems to be induced via adenosine monophosphate-activated protein kinase.
