The elevated expected life out of transgenic flies expressing superoxide dismutase means one to totally free major-scavenging nutrients try sufficient to decelerate aging inside Drosophila ( Tower 2000 ). Furthermore, flies selected having enhanced toughness possess elevated degrees of superoxide dismutase and you will increased effectiveness oxidative stress ( Arking et al 2000 ).
