Summary

Insulin's effects on glucose transport activity and the subcellular distribution of glucose transporters have been examined in isolated human abdominal adipose cells, by measuring 3-0-methylgulcose transport and specific D-glucose-inhibitable cytochalasin B binding to plasma membranes and low-density microsomes, respectively. Insulin appears to stimulate glucose transport in isolated human adipose cell through the translocation of glucose transporters from a large intracellular pool to the plasma membrane as initially postulated for rat adipose and muscle cells.
