The oxidative modification of apolipoprotein (apo) E and lipid peroxidation in human very-low-density lipoprotein (VLDL) induced by peroxynitrite and cupric ions in vitro were strongly suppressed by enrichment with α-tocopherol (α-Toc; 170 μM). α-Toc also suppressed the decrease in the heparin-binding activity of apoE in the VLDL oxidation. These results suggest that α-Toc protected apoE in VLDL from oxidative stress.
