Modulation of iron-mediated oxidant damage in erythrocytes by cellular energy levels.
In this work we have investigated the effects of iron-induced oxidative stress on erythrocytes and their membranes, the importance of haemoglobin oxidation and of the maintenance of the metabolic properties of the cells. The results show that by maintaining the energy requirements of the erythrocyte, methaemoglobin production is minimised under conditions of iron-stress. However, in this situation, the membranes of the erythrocytes become more susceptible to the oxidative damage and increased lipid peroxidation ensues.
