The concept of oxidative stress, well defined as a situation in which cells, tissues, or the whole body present an imbalance between reactive oxygen species (ROS) and antioxidant defenses in favor of ROS levels, is found in several acute and chronic diseases, including cancer. The equilibrium between ROS production and the ability of cells to avoid oxidative damage is a natural challenge for mammalian species since the energy production by oxidative pathways in mitochondria allows the continuous production of free […]
