Dr Nazif Alic paper published in PLOS Genetics

In their recent paper in PLOS Genetics Alic and co-workers explore the complex relationship between Drosophila foxo, a transcription factor with evolutionarily conserved role in ageing, and Anterior open, an ETS-family transcription factor that is a direct target of dFOXO in the adult gut and whose activation can extend lifespan.

The paper is entitled, "Interplay of dFOXO and Two ETS-Family Transcription Factors Determines Lifespan in Drosophila melanogaster"

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.
