Superoxide dismutase: correlation with life-span and specific metabolic rate in primate species.

Abstract

Much evidence now suggests that superoxide dismutase (superoxide:superoxide oxidoreductase, EC 1.15.1.1) may be a major intracellular protective enzyme against oxygen toxicity by catalyzing the removal of the superoxide radical. We examined the possible role this enzyme may have in determining the life-span of primate species. Superoxide dismutase specific activity levels were measured in cytoplasmic fractions of liver, brain, and heart of 2 rodent and 12 primate species. These species had maximum life-span potentials ranging from 3.5 to 95 years. Liver, brain, and heart had similar specific activity levels for a given species, but the levels for different species varied over 2-fold, with man having the highest level. No general correlation was found in the levels with life-span. However, the ratio of superoxide dismutase specific activity to specific metabolic rate of the tissue or of the whole adult organism was found to increase with increasing maximum lifespan potential for all the species. This correlation suggests that longer-lived species have a higher degree of protection against by-products of oxygen metabolism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
