ARUK funded post-doc position available at the IHA

The Institute of Healthy Ageing is currently seeking a post-doctoral research associate to work on the following ARUK-funded project.

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are two devastating, mid-life, neurodegenerative disorders for which no cure is currently available. Large expansions of a hexanucleotide GGGGCC-repeat in the first intron of the C9orf72 gene is the most common genetic cause of both ALS and FTD. We recently developed novel Drosophila models of C9orf72 repeat-induced neurodegeneration (Mizielinska et al Science 2014, 345:1192-1194).

This 3-year post-doctoral position will build on this work by investigating disease mechanisms in a range of C9orf72 fly lines using several approaches including genome-wide transcriptomic and translational analyses in both flies and iPSC-neurons. You will work as part of a collaborative team of investigators in the excellent and supportive scientific research community of UCL.

The post is funded for 3 years in the first instance by Alzheimer’s Research UK and is available from October 2016.

Lectureship for Alexandre Benedetto

Until recently an EU-funded postdoc in David Gems's lab, Alex Benedetto will shortly set up his own laboratory at the University of Lancaster, in the Department of Biomedical and Life Sciences. There he will continue his investigations of the biology of ageing in model organisms, particularly C. elegans. We wish Alex all the best in setting up his new lab! More...

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.
