Dr Marina Ezcurra and Dr Alex Benedetto were both selected to speak at the recent International C. elegans Meeting in Los Angeles (June 24th-28th). The two talks described new breakthroughs in understanding the mechanisms by which age-related pathologies originate in C. elegans, and generated considerable interest. Alex also described a new stress-resistance assay based on death fluorescence, recently discovered in the Gems lab.

The 65th British Society for Research on Ageing Annual Meeting took place at the Institute of Healthy Ageing on July 1st-2nd 2015. 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”.

Stem cells have been found in most tissues/organs. These stem cells produce replacements for lost and damaged cells, and it is not completely understood how this regenerative capacity becomes diminished during ageing. One hypothesis is that stem cells are more likely to sacrifice themselves than risk potentially cancer-causing damage being passed onto progeny. This should reduce the incidence of cancer, but ultimately, may lead to a reduction in stem cells with age that contributes to the ageing process.
Research projects include;
- Analysis of the role of haematopoietic stem cell-specific anti-toxicity mechanisms during ageing
- Long-term tracking of the dynamics of age-based alterations in stem and progenitor cells
- Analysis of stem cell epigenetic alterations during ageing and how this alters gene expression
- Analysis of the effect of calorific restriction on murine haematopoietic stem ageing.
- Cell signalling
- The biology of ageing and the role of somatic stem cells in this process.
