The research of my group is related to the biological phenomenon of oxidative stress. For several years we have been investigating the oxidative stress response of cells and organisms and the protective influence of antioxidants. In the focus within this topic is the oxidative damage to proteins, the protection of proteins from oxidation and the fate of a protein if it is oxidized. This damage is caused by the biological phenomenon of “oxidative stress”, and by various other conditions, such as hyperglycemia (high blood glucose). Investigations focus on how (aging) cells deal with macromolecules that underwent oxidative damage and modification, and with the effects of nutritional components on these processes.
