Previous studies demonstrated that an adipose tissue-specific element(s) (ASE) of the murine GLUT4 gene is located between -551 and -506 in the 5′-flanking sequence and that a high-fat responsive element(s) for down-regulation of the GLUT4 gene is located between bases -701 and -552. A binding site for nuclear factor 1 (NF1), that mediates insulin and cAMP-induced repression of GLUT4 in 3T3-L1 adipocytes is located between bases -700 and -688. To examine the role of NF1 in the regulation of GLUT4 gene expression in white adipose tissues (WAT) in vivo, we created two types of transgenic mice harboring mutated either 5′ or 3′ half-site of NF1-binding sites in GLUT4 minigene constructs. In both cases, the GLUT4 minigene was not expressed in WAT, while expression was maintained in brown adipose tissue, skeletal muscle, and heart. This was an unexpected finding, since a -551 GLUT4 minigene that did not have the NF1-binding site was expressed in WAT. We propose a model that explains the requirement for both the ASE and the NF1-binding site for expression of GLUT4 in WAT.
