Abstract:
The nematode worm C. elegans is a well established model organism used to answer fundamental questions in animal biology. In the lab, C. elegans is cultured on lawns of E. coli, a microbe derived originally from the human gut. We have discovered a mutant of E. coli that extends worm lifespan. This lifespan extension is caused by decreased folate synthesis in microbe. A sulphonamide drug that inhibits E. coli folate synthesis causes a dose-dependent increase in C. elegans lifespan without negative effects on either the microbe or the animal. Thus, this intervention may be transferable to more complex animals to slow ageing and improve health.
