Synopsis and Key Points:

Researchers have made a significant breakthrough that may benefit patients with bowel cancer.

Main Digest

Dr Sandra van Schaeybroeck and her team have discovered how two genes cause bowel cancer cells to become resistant to treatments used against the disease. The research, which was funded by Cancer Research UK, was published this month in the prestigious international journal Cell Reports.

The activity of the two genes, called MEK and MET, was uncovered when the researchers looked at all the different pathways and interactions taking place in bowel cancer cells.

Dr van Schaeybroeck and her group found that these bowel cancers switch on a survival mechanism when they are treated with drugs that target faulty MEK genes. But when the researchers added drugs that also block the MET gene, the bowel cancer cells died.

The team are now testing a new approach to target these two genes in the most aggressive forms of bowel cancer in a European Commission funded clinical trial that is being led by Dr van Schaeybroeck.

Currently over 40,000 people are diagnosed with bowel cancer in the UK each year and over 16,000 patients die of the disease. More than half of patients develop the aggressive form of the disease which does not respond to standard therapy, the five year overall survival in this patient group is less than five per cent.

Study author Dr Sandra van Schaeybroeck, from the Center for Cancer Research and Cell Biology (CCRCB) at Queen's University, said: "We have discovered how two key genes contribute to aggressive bowel cancer. Understanding how they are involved in development of the disease has also primed the development of a potential new treatment approach for this disease."

Queen's University Vice-Chancellor, Professor Patrick Johnston, said: "Understanding the genes that cause bowel cancer is a key focus of our research. Our discoveries in this deadly disease have identified a new route to clinical application for cancer patients."

Professor David Waugh, Director of the CCRCB at Queen's, said: "The publication of this research by Dr van Schaeybroeck and her team demonstrates our commitment to performing excellent science here in Belfast that can be directly translated to the clinic."

The clinical trial, which is called MErCuRIC and is due to start in September, will deliver personalized medicine to Northern Irish patients and patients from other European countries. Overall, the pan European collaborative effort will involving 13 research/clinical teams from nine European countries.

The MErCuRIC clinical trial is supported with 6 million euro grant by the European Commission to a European Consortium led by Queen's University Belfast. This clinical trial will deliver personalized medicine to Northern Irish patients and patients from other European countries. Overall, this pan European collaborative effort involving 13 research/clinical teams from 9 European countries.
