Project description
Cell-based anti-ageing drug assessment platform
Population ageing together with age-related diseases make ageing research increasingly important. Previously, the project team developed the CellAge epigenetic clock, which is based on DNA methylation and can accurately detect subtle ageing changes in human primary cells in vitro after a short-term anti-ageing drug treatment using rapamycin and trametinib. The EU-funded AgePhagy project is now connecting the CellAge clock to their autophagy drug library to test the commercial viability of this anti-ageing drug assessment platform. To further validate the clock as a robust human ageing biomarker, the team will combine its outputs with in vivo longevity assays in Drosophila. The final outcome will be an innovative accelerated discovery platform for anti-ageing drugs.
Objective
The steeply increasing ageing population, and accompanying rise of age-related diseases will soon have profound societal and economic effects, making ageing research increasingly important and outcome of this grant impactful. Our most promising way to improve health in the elderly is by replicating decades of genetic finding in model organisms of healthy long-lived mutants to pharmacological approaches. This will enable transition of these findings to clinical trials. In the CancerPhagy project, we showed that genetic upregulation of autophagy, major cellular degradation pathway, increased lifespan, which we aim to mimic by pharmacological treatment. To this end, we developed the CellAge epigenetic clock, which is based on DNA methylation and which is the first clock that accurately detects subtle ageing changes in human primary cells in vitro upon a short anti-ageing drugs treatment, as shown using rapamycin and trametinib. This differentiates our clock from other available epigenetic clocks which are designed to accurately determine human age in years. By connecting the CellAge clock to autophagy drug library we will test the commercial viability of our anti-ageing drug assessment platform. To further validate our CellAge clock as a robust human ageing biomarker, we will combine its outputs with longevity assays in vivo in Drosophila. The final outcome will be an innovative and accelerated discovery platform for sought after anti-ageing/geroprotector drugs, which we will in this first instance test autophagy modifier drugs. Throughout the project we will closely collaborate with our industrial collaborator, GSK and UCL Business, which will assure we maximise the potential of our platform. Our ultimate goal is to uncover novel autophagy modifiers with anti-ageing properties and to launch the CellAge clock as the most advanced platform for expedited discovery of anti-ageing compounds.
