A Little More Recent Research on the Topic of Reactive Oxygen Species

To follow on from the post on reactive oxygen species in aging earlier today, I thought I’d direct your attention to a few more recent papers that approach this topic from various directions. To recap, it has long been known that the level of oxidative damage in cells increases with age, a state of affairs called oxidative stress, and that this is largely a product of changes in mitochondria, the power plants of the cell where more energetic chemistry takes place. What does this mean? Cells are intricate, dynamic, mostly fluid bundles of molecular machinery, and roving reactive molecules – such as reactive oxygen species (ROS) – cause harm by reacting with this machinery so as to prevent it from functioning correctly. When there are … Continue reading A Little More Recent Research on the Topic of Reactive Oxygen Species
