Abstract
The effects of iron deficiency on the expression and
function of transferrin receptors was studied in K562
human leukemia cells. It was found that cells respond
immediately by speeding up the transferrin cycle i.e. the
rate at which saturated transferrin is internalized, the
iron removed, and the apo-Tf released. They respond, in this way to iron deficiencies both outside and within the cell. When grown for periods over 24 hours in iron deficient environments, cells developed additional receptors
for transferrin. This response, however, was affected only by a deficiency within the cell.
