The Broad Spectrum of Responses to Oxidative Stress in Proliferating Cells
Proliferating mammalian cells exhibit a broad spectrum of responses to oxidative stress, depending on the stress level encountered. Very low levels...

Modulation of Cellular Signaling Processes by Reactive Oxygen Species
Exposure of cells to reactive oxygen species (ROS) may result not only in cell death by excessive oxidation of biomolecules but also cause the...

Mitochondrial Free Radical Production, Antioxidant Defenses and Cell Signaling
Mitochondria were classically recognized as the organelles that produce the energy required to drive the endergonic processes of cell life, but now...
-
Protein Repair and Degradation
Protein oxidation is one of the important processes taking place during oxidative stress. Numerous amino acids can be modified within proteins...
-
Superoxide Dismutases and Catalase
Superoxide dismutases (SODs) and catalase represent the primary enzymatic defense against reactive oxygen species. Both enzymes are present in...
