MnSOD over-expression extends Drosophila lifespan and alters metabolic rates. For these assays four lines were used: control, MnSOD(2)22, MnSOD(2)20, and MnSOD(2)12. (a) The percentage of animals alive is plotted against animal age. (b) Plots of log mortality rate against age. (c) CO2 production as measured by the average nanoliters of CO2 produced per minute plotted against age.
