Cox Lab of Ageing and Cell Senescence

 

My lab studies the basic biology underpinning ageing and age-related diseases. We aim to use that knowledge to improve the health of older people through development of new interventions and treatments to promote healthy ageing by treating age-related diseases at cause.

Using a combination of model systems, we look at genes and biochemical pathways that influence health outcomes in ageing, with a particular focus on the process of cellular senescence. Our work aims to define molecular and genetic pathways that govern cell senescence and that underlie organismal ageing and frailty. We are following up our pathway discovery with targeted intervention using pharmacological agents to delay or inhibit senescence, or even reverse detrimental phenotypes.

HoL ageing report front page

The House of Lords Science and Technology Select Committee published on 15th January 2021 its in-depth report on 'Ageing: Science, Technology and Healthy Living' which makes very specific recommendations to the UK Government.

 

 

The following key findings are taken directly from the press release accompanying the report. I quote:

  • New Science has potential to improve healthy ageing benefiting the individual, the NHS and society
  • UK is global leader in drug development and new technologies with promising advances
  • However, Government is missing its key healthy ageing targets and must act now
  • Inequalities in healthy life expectancy are stark; COVID-19 has highlighted concerns
  • Evidence that the rate of multi-morbidity is increasing; designated clinicians required

I provided both oral and written evidence to the committee which they refer to extensively in the report – a link to the report can be found here

science question time

Science Question Time on "Designing research to serve ageing populations" sponsored by MSD. The report (published 24th February 2021 and available here) highlights the importance of biomedical research in ageing, together with the need to include older people in clinical trials of therapies that will be of benefit to them. 

 

Quote from the report:

"The COVID-19 pandemic has created unprecedented strain on health systems and societies around the world. It has shone a light on health inequalities and reinforced the importance of fostering health resilience. It has also highlighted the importance of scientific research to protect the health and wealth of societies. Science Question Time held on 25 November 2020 brought together leading scientists and policymakers to reflect upon these factors and think about the broader implications for R&D, asking the key question: ‘How can we design research to serve ageing populations and those with comorbidities, and ensure that research is reflecting our societal aim of achieving healthy longevity?’"

Healthy Ageing: From molecules to organisms: POSTPONED DUE TO COVID-19

27 - 29 May 2020 Wellcome Genome Campus, UK

The third conference in this series will focus on recent discoveries and current challenges in ageing research, with a focus on translating basic research insights into health improvement for older people.

Ageing can lead to declining health and function, and it is the major risk factor for cancer, neurodegenerative and cardiovascular disease. We aim to explore the mechanisms of ageing in cells, tissues and organisms in order to identify interventions that can ameliorate its negative effects.

The conference will focus on how recent developments in cell- and immune-senescence, neuroinflammation, stem cells and epigenetics are leading to an increased understanding of the ageing process. This year’s meeting will also highlight research into the ageing brain and nervous system and discuss lifestyle interventions for health improvement.

The meeting is aimed at scientists, clinicians and drug developers involved in research into ageing and other relevant fields.

What causes age-related disease and can ageing be treated?

 

Ageing and age-related diseases affect some people much more than others: there is no one fixed way to age and everyone is different. While we know that a good diet, exercise and plenty of sleep are important to maintain health, other factors out of our control (e.g. genes, environment) can lead to significant ill health and disability in later life. The vast majority of older people suffer from several chronic age-related diseases simultaneously - this is termed co-morbidity. 

 

We now know that changes to cells as they age, termed cell senescence, can be critical in causing many different diseases of ageing. Exciting new research from labs around the world has shown that removing senescent cells can improve health in later life, and even extend lifespan in mice. 

 

Cells undergo senescence in several different ways in response to DNA damage, activation of oncogenes or simply after they have undergone a large number of cell divisions until their telomeres (repetitive DNA structures at the ends of the chromosomes that shorten at every cell division cycle) have become critically short. Senescence is an important tumour suppressor mechanism to prevent damaged cells from dividing, but the many changes cells undergo as they become senescent leads to them altering their local environment, including degrading tissue structure and promoting a pro-inflammatory and pro-cancer environment. 

 

By identifying the biochemical pathways and specific molecules involved, we aim to develop ways of altering the rate or outcomes of cell senescence, in order to better treat age-associated diseases and frailty.

BIRAX conference November 2021

As well as diseases traditionally associated with ageing, we are also looking at Type 1 diabetes as a model of premature ageing, studying whether cell senescence contributes to bone fragility and morbidity in diabetes. This is part of a collaboration under the BIRAX/British Council scheme with Prof Rivka Dresner-Pollak in Jerusalem, and funded by Diabetes UK. Here you can see the talk I gave at the latest BIRAX meeting on our progress (forgive the remote broadcasting issues with slide size) :

Approaches we take to understand and treat ageing

Expand All

Cell senescence is a state of cell cycle arrest with cell growth, morphological changes and alteration in gene expression patterns leading to secretion of pro-inflammatory mediators and enzymes that damage tissue structure.

Senescent cells are pro-inflammatory and damaging, leading to diseases of ageing

 

 

We are also interested in investigating the role of a gene WRN which when mutated in humans leads to the premature ageing Werner’s syndrome. That a single gene can result in the early development of many age-related diseases including atherosclerosis, diabetes, cataracts, osteoporosis and cancer provides very strong evidence that there is a central underlying cause of many of the diseases of later life. Mutation of a closely related gene EXD2 also leads to genome instability and we are interested in the interplay between efficient DNA repair and maintenance of cellular longevity. We are studying the effect of WRN loss and its biochemcial activities in worms, flies and humans.

Cell senescence can occur as a result of many different cellular stresses. These can include DNA damage signalling arising from shorted telomeres after many rounds of cell division, more acute forms of DNA damage e.g. after exposure to ionising radiation or UV light, activation of cellular oncogenes, high levels of nutrients which drive cells into a hyper-growth phenotype, hormones (including insulin and insulin-like growth factor) as well as generalised intracellular and extracellular stresses (e.g. high ROS). These feed into key pathways that modulate the cell's response. Our focus is particularly on mTOR as master regulator, WRN as a key DNA damage response protein implicated in ageing, and p53, the tumour suppressor protein that when hyperactive causes ageing.

 

We are exploiting the power of multiplex proteomics to identify molecular pathways important in senescence.

signalling pathways regulate cell senescence

Key molecules involved in driving and maintaining cellular senescence are the tumour suppressor proteins p16 and p53, and the p53-activated cyclin-dependent kinase inhibitor p21, while the mTORC1 kinase and its downstream effectors are antagonistic and promote cell growth and proliferation.  

The fruit fly Drosophila allows us to explore how changes in certain age-related genes influence the overall stability of the genome. We have identified a WRN-like exonuclease in flies (Saunders et al 2008 Aging Cell 7 (3) 418-425) and are using this to study the relationship between DNA repair, genome instability and ageing, as well as studying ageing in normal (wild type) flies and those with stem cell defects. Fly work is carried out in collaboration with Dr Robert Saunders of the Open University, together with Prof Petros Ligoxygakis in Oxford. 

Drosophila WRN exonuclease

We are taking two approaches towards developing novel senomodifying interventions: target-based against molecules identified as important in our proteomics studies, together with phenotypic screens for correction of senescent phenotypes.

We are actively designing new ways to identify drugs that can modify senescence and hence help to treat or even prevent the diseases of ageing. We have recently optimised a screening platform based on a biosensor that can detect very low levels of pro-inflammatory IL-6.

Model systems we use to study ageing:

 

Human cells cultured in the lab allow us to identify biochemical pathways of senescence and to test drugs directly in human cells with direct relevance to human ageing.

 

Werner syndrome, a premature ageing disease in humans, is cause by mutation of a single gene WRN. Working out how WRN acts in cells to prevent premature ageing, and how loss of function of just one gene causes multiple diseases of ageing is important in working out how to treat age-related diseases.

 

The fruit fly Drosophila melanogaster: we have identified the WRN exonuclease gene in flies, and have tested its roles in development, DNA replication, repair and recombination. We have also carried out biochemical analysis of the WRN nuclease activity.

 

The nematode worm C. elegans allows us to test the effect of genes and/or chemical interventions on whole organism ageing within a very short time frame. Worms share more than 50% of genes with humans and show very similar ageing pathways, including premature ageing when the worm version of WRN (wrn-1) is mutated.
