The Gems lab welcomes new research fellow Dr Jennifer Lohr, from Kiel University (Germany) - Jennifer is investigating evolutionary and mechanistic aspects of ageing in C. elegans - and says farewell to Dr Marina Ezcurra who is taking up a new position as a lecturer and Queen Mary's University of London.
A new joint study from the Gems and Tullet labs was published in Aging Cell, describing how the effects of SKN-1 on oxidative stress and lifespan can be uncoupled. This implies that this transcription factor, similar to mammalian Nrf2, influences lifespan by mechanisms other than protection against oxidative stress.
David Gems published two new essays on the general nature of ageing, “Aging: natural or disease? The view from medical textbooks” (in “Anti-aging drugs: from basic research to clinical practice” Royal Society of Chemistry; with Sarah Janac and Brendan Clarke), and “What is aging? ” in “AGE - From the anatomy of life to the architecture of living” (Crosstalks/VUB Press).
Marina Ezcurra gave a talk at the British Society for Research on Ageing, Thanet Sornda presented a poster at the International C. elegans Meeting in Los Angeles, and Hongyuan Wang at the Gordon Research Conference on the Biology of Aging in Switzerland. David recently gave talks at the conference "The Ageing Cell" at the Babraham Institute, and at Ghent University (Belgium), Leeds University, and the Max Planck Institute for Biology of Ageing (Germany).
Two master's (M.Res.) students from the Gems lab obtained Ph.D. positions: Sophie van Schelt at the Max Planck Institute for Biology of Ageing (Cologne), and Chenhao Yang at the University of Maine. Well done both!

Currently a Wellcome Trust-funded postdoc in David Gems' lab, Marina Ezcurra will shortly be taking up a Lectureship in Neurobiology at the School of Biological and Chemical Sciences, Queen Mary University of London, where she will be setting up her own laboratory. There she will continue her investigations of the biology of ageing in model organisms, particularly C. elegans. The new post will also involve contributing to a joint programme with the University of Nanchang in the People's Republic of China. We wish Marina all the best in setting up her new lab!

New report by Yuan Zhao and Ann Gilliat in Nature Communications describes causes of death in ageing C. elegans
A new study from David Gems' lab describes a major life-limiting pathology in C. elegans, thereby providing insight into the mechanisms underlying lifespan determination in this organism.
For several decades, numerous research groups have studied how manipulation of a wide variety of genes can affect C. elegans lifespan, as a route to understanding the ageing process. Yet the mechanisms of ageing itself remain poorly understood. In a different approach this new study focuses on the actual causes of death in ageing populations and the mechanisms leading up to them. It demonstrates that C. elegans exhibit two different types of death that are differentially affected by treatments that increase lifespan. Analysis of such differential effects (or mortality deconvolution) allows the complex shapes of survival curves and mortality profiles to be explained. This study begins to bridge the gap between genetics and lifespan by means of analysis of the senescent pathologies that determine lifespan.

Congratulatsions to Adam Dobson and Nazif Alic whose paper, "Nutritional Programming of Lifespan by FOXO Inhibition on Sugar-Rich Diets," has just been published in Cell Reports. Their study shows that a history of feeding on a high sugar-diet shortens lifespan and changes gene expression. These changes appear to be mediated by FoxO/Daf16 in both flies and worms

On Saturday, November 26 2016 BBC Radio 4 broadcast a 1 hr programme entitled "Logan's Run and Intergenerational War", presented by Ed Howker, with extensive contributions from IHA Co-Director Professor David Gems. The programme included in depth discussion of the impact of the ageing of populations, and the prospects for treatments for ageing to improve late-life health. Among other contributors to the programme were former Universities and Science minister David Willetts and the actress Jenny Agutter.
The programme is available for a short period via the BBC iPlayer at http://www.bbc.co.uk/programmes/b083j672#play

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.

Speakers at the conference included Claudio Franceschi (Bologna), Paul Shiels (Glasgow), Jesus Gil (Imperial), and Avan Aihie Sayer (Southampton). They also included several speakers from the IHA: Lazaros Foukas, who described how ageing can be slowed down in mice by reducing PI3 kinase signalling, Cathy Slack (whose talk was awarded the Korenchevsky Prize) spoke about how Ras signalling controls fruitfly ageing, and David Gems who gave a welcome address, including a discussion of “The ageing-disease false dichotomy”.

A new article has just been published in the journal Frontiers in Genetics, entitled “The aging-disease false dichotomy: understanding senescence as pathology” (June 16, 2015, vol. 6, article 212). The article describes how a number of current worries about the prospects of treatments for ageing are misconceptions generated the traditional but incorrect view that ageing is distinct from age-related disease. It also proposes a new understanding of how interventions that extend lifespan operate that reconciles opposing views of traditional medicine and biogerontology.
