What we do

Our research primarily aims to understand and exploit metabolic drivers of cancer in order to generate new treatments and identify those most at risk of disease.  This includes studying novel genes that regulate metabolism and linking molecules in blood associated with obesity and diabetes to cancer outcomes. Most recently we have been learning how cancer cells can become resistant to drugs by recycling metabolites from the tumour environment.  

Why it is important

While we have long understood that metabolism in cancer cells is different from normal cells, we still don’t understand how cancer genes are related to these effects.  It is also not clear why aspects of metabolic disease or diet appear to increase risk of cancer or affect progression disease.  By understanding the metabolic pathways that are necessary for tumour growth and survival we can devise new strategies to treat, diagnose and prevent cancer. 

How it can benefit patients

Most patients initially respond to chemotherapy; however when disease returns it is often less responsive to chemotherapy and inevitably becomes drug-resistant and fatal.  We aim to find new metabolic genes to target with drugs, or other ways to prevent or reverse resistance.  At the other end of the patient journey, we urgently need better ways of detecting aggressive cancer early on when treatment is most likely to cure the patient.
