Oxygen, stress, and antioxidants: Should we be scared of reactive oxygen species?
Presented by Ron Mittler, Division of Plant Sciences and Technology, College of Agriculture Food and Natural Resources and Interdisciplinary Plant Group. University of Missouri and Department of Surgery, University of Missouri School of Medicine

Oxygen is essential for life, but it also has a dark side. In the presence of oxygen (that is abundant in our atmosphere) all cells can and do produce toxic compounds called reactive oxygen species. These compounds can attack proteins, DNA, lipids, and other cellular components and induce a dangerous state called ‘oxidative stress’. The damaged caused by reactive oxygen species was blamed for aging, cancer and several other diseases, and a whole industry of antioxidants (for example, Vitamin C and E) emerged on the basis of this blame. In recent years however a complete overhaul of this concept is taking precedence, and numerous studies have shown that reactive oxygen species are required for life, acting as important regulators of many essential processes in different organisms. Examples for these include the immune response, proliferation of stem cells, and responses of cells to different stresses and pathogens. So, what should we believe? In this presentation, Dr. Mittler will provide a balanced view of these two opposing viewpoints and show using different examples that, as with almost everything in life, balance is the answer.
