Competition Funded PhD Project (European/UK Students Only)
Our body tissues are frequently exposed to a wide-range of toxic insults that could cause significant damage (1). Toxic molecules are generated within us (as byproducts of metabolism and inflammation) as well as from environmental insults (e.g. radiation, pollution or cigarette smoke). In order to defend themselves, our tissues must switch on powerful protective strategies to help resist and repair the damage (2). Without these pathways, tissues would rapidly age, accumulate cancer-causing mutations and develop disease. Given the same protective mechanisms can be hijacked by cancer cells and drive resistance to anti-cancer treatments (3), our findings will also have important implications for cancer therapy.
Whilst their importance is clear, the exact identity of these protective pathways and how they function are poorly understand. In this interdisciplinary project, we will explore the diverse cellular mechanisms that protect body tissues from stress and investigate their genetic links to human disease (including infertility, chronic wounds and cancer). For this, we will combine state-of-the-art techniques in Drosophila models with cutting-edge human genetic epidemiology. The work has wide-ranging clinical relevance, not only for treating conditions such as infertility and cancer, but clinical activation of these pathways could also help protect patient tissues during surgery.
This inter-disciplinary and cross-institutional PhD project is available on the “MRC GW4 BioMed Doctoral Training Program”. This project offers a unique opportunity for training in a range of state-of-the-art techniques. The student will learn skills in multidisciplinary quantitative methods as well as experimental in vivo biology. The Drosophila studies will include live imaging, genetic manipulation and relevant molecular biology. The Population Health studies will employ cutting-edge genetic epidemiology approaches, including analysis of genetic and epigenetic data. The student will be embedded in the vibrant research environment at the University of Bristol and have the opportunity to interact with our collaborators at the University of Cardiff and internationally (including ETH Zurich).
