Cambridge scientists have discovered that cancer cells 'hijack' a process used by healthy cells to spread around the body, completely changing current ways of thinking around cancer metastasis. The team based at the Cancer Research UK Cambridge Institute, University of Cambridge, found that blocking the activity of the NALCN protein in cells in mice with cancer triggers metastasis. The research, which was published in Nature Genetics today, also discovered that this process is not just restricted to cancer. Group Leader for the study and Director of the CRUK Cambridge Centre, Professor Richard Gilbertson, said: "These findings are among the most important to have come out of my lab for three decades. Not only have we identified one of the elusive drivers of metastasis, but we have also turned a commonly held understanding of this on its head, showing how cancer hijacks processes in healthy cells for its own gains. If validated through further research, this could have far-reaching implications for how we prevent cancer from spreading and allow us to manipulate this process to repair damaged organs." Despite being one of the main causes of death in cancer patients, metastasis has remained incredibly difficult to prevent, largely because researchers have found it hard to identify key drivers of this process that could be targeted by drugs. Lead researcher on the study Dr Eric Rahrmann, said: "We are incredibly excited to have identified a single protein that regulates not only how cancer spreads through the body, independent of tumour growth, but also normal tissue cell shedding and repair. We are developing a clearer picture on the processes that govern how cancer cells spread. We can now consider whether there are likely existing drugs which could be repurposed to prevent this mechanism from triggering cancer spreading in patients." The research was funded by CRUK, whose Director of Research, Dr Catherine Elliott, said: "Once cancer has spread from the first tumour, it is harder to treat because we are looking at multiple sites in the body and working with new tumours that may be resistant to treatment. Discovering that a cancer has spread is always devastating news for patients and their families and so we are delighted to have supported this incredible research which may one day allow us to prevent metastasis and turn cancer into a much more survivable disease."
