Electron acceptors in biological systems, termed "oxidants", have been associated with numerous cytopathic conditions. In particular, oxygen-derived free radicals have been shown to induce various subcellular oxidative injuries which can lead to different types of pathologies. It has also been suggested that oxidative stress induced by xenobiotics can determine specific subcellular alterations in in vitro models. An oxidative imbalance in cells seems in fact to affect intracellular functions including the expression of some growth factor surface receptors. In this work, we observed a specific early alteration of the microfilament system and the microtubular network induced in K562 cells by oxidative stress. In particular, we hypothesize that oxidative imbalance could lead to an impairment of the expression of these receptors, such as transferrin receptors, via a modification of the cytoskeleton. This could represent a general mechanism by which a modification of receptor regulation can lead to cell aging, injury or death.
