Cell paper reveals how a cancer drug makes fruit flies live longer

A paper by researchers from the IHA Dr Cathy Slack and Dr Nazif Alic demonstrate new targets for drugs against ageing. Their research published in Cell shows how inhibition of the Ras-Erk-ETS pathway extends fly lifespan.

PLoS One paper for Dr Cathy Slack

25 October 2012

Congratulations to Dr Cathy Slack (Partridge Laboratory) on the publication of her paper 'Activation of AMPK by the Putative Dietary Restriction Mimetic Metformin is insufficient to Extend Lifespan in Drosophila' in PLoS One.

Abstract -
The biguanide drug, metformin, commonly used to treat type-2 diabetes, has been shown to extend lifespan and reduce fecundity in C. elegans through a dietary restriction-like mechanism via the AMP-activated protein kinase (AMPK) and the AMPK-activating kinase, LKB1. We have investigated whether the longevity-promoting effects of metformin are evolutionarily conserved using the fruit fly, Drosophila melanogaster. We show here that while feeding metformin to adult Drosophila resulted in a robust activation of AMPK and reduced lipid stores, it did not increase lifespan in either male or female flies. In fact, we found that when administered at high concentrations, metformin is toxic to flies. Furthermore, no decreases in female fecundity were observed except at the most toxic dose. Analysis of intestinal physiology after metformin treatment suggests that these deleterious effects may result from disruptions to intestinal fluid homeostasis. Thus, metformin appears to have evolutionarily conserved effects on metabolism but not on fecundity or lifespan.
