Scientists in the College of Medical and Dental Sciences have been awarded nearly £3 million from Cancer Research UK to investigate cancers that are resistant to treatment.
Dr Clare Davies and Dr Daniel Tennant were commended by the charity for submitting ambitious bids based on ‘exciting’ findings from their existing research projects. Cancer Research UK said that both research programmes, being run over six years, could eventually help improve the outcome of patients with some of the most difficult to treat cancers such as brain, pancreatic and oesophageal.
Dr Davies, senior research fellow within the Institute of Cancer and Genomic Sciences, said her team had identified a protein linked to poor survival in breast cancer patients. The protein, called PRMT5, is found in high levels in many types of cancer. Dr Davies’s research has shown that the protein is a key player in helping breast cancer cells grow, survive and become resistant to drugs.
“Firstly we want to find out how PRMT5 contributes to breast cancer growth and drug resistance,” said Dr Davies. “That will help us identify new ways to target cancer with drugs.
“Secondly, we hope to identify which cancer patients will respond favourably to treatments that target PRMT5, thereby limiting the exposure of patients to drugs that may not work for their particular type of cancer.
“We’re incredibly excited that this research is being funded by Cancer Research UK, as we will be able to answer complex scientific questions in a level of detail that we hope will make a real difference to the lives of cancer patients in the very near future.”
Dr Tennant’s research is looking at targeting drug resistant cells in one of the deadliest forms of breast cancer called triple negative breast cancer. His research is also investigating the same type of drug resistant cells in an aggressive type of brain tumour called glioblastoma.
“We know that certain cancer cells don’t get enough oxygen and it is these that are most resistant to treatment,” said Dr Tennant, senior lecturer within Institute of Metabolism and Systems Research.
“We’ve developed a new technique to identify molecules that the cancer cells in low oxygen rely on to survive. We think that targeting these molecules could be a good way to kill treatment-resistant cells.
“Brain tumours are notoriously difficult to treat and we urgently need new approaches to tackling them. Cancer Research UK has made transforming brain tumour research a priority to help more people with the disease, which has devastatingly low survival rates.”
Matt Kaiser, Head of Discovery Research at Cancer Research UK, said: “Cancer cells that don’t respond to therapies present a big barrier to successful treatment for patients. We hope that these exciting projects will boost our understanding of the signals in cells that many cancers rely on for growth and survival. This will be key to developing much more successful, targeted treatments for patients in future.”
