N2 - The effects of NO in its environment may vary considerably depending on various factors. This study shows oxidative mechanism of cellular membrane alterations, which is not associated with triggering of ONOOH generation but is induced by pure NO. Our investigation examined the influence of low concentration of NO (0.1; 0.2 mmol/l) on the qualitative changes of structure and dynamics of erythrocyte membrane. NO causes a statistically significant increase in membrane fluidity on different depths of lipid bilayer that is correlated with increase of lipids peroxidation. Statistically significant changes in the conformational state of cytoskeleton proteins were also detected. NO can be considered as a molecule responsible for determining rheological properties of erythrocytes membrane. Therefore, we propose that NO acts as pro-oxidant molecule at concentrations for which membrane appeared to be the first target before it entered the cytosol. © 2007 International Federation for Cell Biology.
