摘要

I recently read the article by Csiszar and colleagues (1). They show for the first time, in fibroblasts from 13 primate species including anthropoids and humans, that the mean level of reactive oxygen species (ROS) is low in long-lived compared with short-lived animals. Their measurements are not "ROS production" because they were performed in whole cells, and thus cellular antioxidants interfere. But the negative correlation between mitochondrial ROS production (mtROSp) and longevity observed in many studies in mammals and birds (2) prevailed even with interference from cellular antioxidants. Long-lived animals have less endogenous antioxidants (3-5) and less mtROSp (2) than short-lived ones. Therefore, in whole cells, both factors would tend to cancel each other, but still the low mtROSp of the long-lived species seems to have predominated in this case.
