Caption: The D737 compound was tested on flies with a regular human A gene (top graph) and flies with a mutant gene that causes extra buildup of the peptide (bottom graph). For each group, flies received none of the compound (black line), or concentrations of 2, 20 or 200 micromolar (blue, grey and red lines, respectively). Flies -- particularly those with the mutant gene -- survived longer when administered the compound.
