Kinetic analysis of glucose transporter trafficking in fibroblasts and adipocytes.

Insulin regulates hexose uptake by the redistribution of glucose transport proteins from intracellular compartments to the cell surface. We have submitted the trafficking of GLUT1, GLUT4, and GLUT1/GLUT4 chimeras to a mathematical analysis in the context of different models. Our data suggest that a model with one intracellular and one cell surface… (More)
