Redox imbalance in development and disease

Living cells are constantly exposed to reactive oxygen and nitrogen species which may lead to modifications of the cellular macromolecules, mutations and eventually cell death. Increased oxidative stress - i.e. an imbalance in the cellular redox homeostasis - is observed during e.g. smoking, aging and inflammation and has been associated with several chronic diseases including atherosclerosis and cancer.

In a variety of studies ranging from primary cells, cell culture and animal models to clinical trials, we study the effects of oxidative insults on the redox homeostasis as well as the possible benefit of intervention with bioactive compounds to selected groups of animals or humans. Together with measurements of oxidative damage-an effect of oxidative stress-we investigate the link between oxidative stress and various pathological conditions. Our primary goal is to understand the role and mechanism of altered redox status in disease development and thereby pave the road for better prevention strategies and pharmacotherapy for animals and humans.
