Regulation of expression of glucose transporters by glucose: a review of studies in vivo and in cell cultures

Glucose transporters are membrane-embedded proteins that mediate the uptake of glucose from the surrounding medium into the cell. Glucose is the main fuel for most cells, and its uptake is rate-limiting for glucose utilization. For this reason, it is expected that glucose transport is tightly regulated. Whereas rapid regulation of glucose transporters by hormones has been known for some time, the regulation of glucose transporters by substrate …
