  • Title: Regulatory elements in the insulin-responsive glucose transporter (GLUT4) gene.
    Author: Ezaki O.
    Journal: Biochem Biophys Res Commun; 1997 Dec 08; 241(1):1-6. PubMed ID: 9405224.
    Abstract:
    GLUT4, the insulin responsive-glucose transporter, mediates the rate limiting step of glucose metabolism in skeletal muscle and adipose tissue. GLUT4 expression is up-regulated by exercise training and thyroid hormone treatment and is down-regulated by fasting, streptozotocin-induced diabetes, obesity, high-fat diet, and denervation. Since overexpression of GLUT4 in insulin resistant db/db mice and high-fat diet-fed mice has been observed to dramatically improve glycemic control, increasing GLUT4 expression may be an effective strategy with which to alleviate insulin resistance. This review discusses recent findings on the regulation of the GLUT4 gene and on progress in the identification of regulatory elements in the promoter of the gene.
