GSH: A MARKER FOR OXIDATIVE STRESS IN HUMAN CELL CULTURES Gueli Maria Concetta Dipartimento di Biomedicina Sperimentale e Neuroscienze Cliniche (BioNEC), Università degli Studi di Palermo. Reactive oxygen species (ROS) play an important role in physiological processes, but when being in excess ROS react readily with proteins, lipids, carbohydrates, and nucleic acids, often inducing irreversible functional alterations or even complete destruction. In cells, under physiological conditions, the production and detoxification of ROS are more or less balanced. GSH functions as antioxidant and the oxidative conversion of GSH to GSSG is widely recognized as a reliable index of oxidative stress. The…
