Popis: Glucose entry into mammalian cells is facilitated by a family of glucose transport proteins known as GLUTs. Treatment of 3T3-L1 adipocytes with the Cdk5 inhibitor roscovitine strongly inhibits insulin-stimulated/GLUT4-mediated glucose transport. Inhibition of glucose uptake occurs within 2–6 min of the addition of roscovitine and is slowly reversed. The roscovitine treatment interferes with neither the translocation nor the insertion of GLUT4 into the plasma membrane. These studies support recent evidence showing that insulin-stimulated Cdk5 is implicated in the regulation of GLUT4-mediated glucose uptake in 3T3-L1 adipocytes. J. Cell.
