Zusammenfassung
Aims: Oxidative stress has been identified as a major pathogenic factor in many liver diseases including alcoholic and non-alcoholic liver disease, hereditary hemochromatosis, and chronic hepatitis C. To mimic such conditions in vitro, oxidants such as H2O2 or redox-cycling drugs such as doxycyclin or antimycin A are routinely applied to cultured cells. However, these experiments are typically performed at air oxygen levels of 21%. This is hyperoxic as compared to the normal tissue environment considered to be at ca. 1–2% O2. We here aimed at developing an enzymatic system that allows to independently control ox…
