How much Indy does it take to extend life?

The maximum lifespan of drosophila is provided by a moderate amount of the protein of the mutant Indy gene (from the English I'm Not Dead Yet – I'm not dead yet); a little less is its overexpression. Flies with two normal copies of this gene live significantly less.
