INHERITED genes may be more of a cause of cancer than the medical profession had previously thought, researchers in Scotland and Italy said yesterday.
A new study into a rare type of pancreatic cancer reveals that we may inherit more than twice the number of “cancer genes” than experts previously stated.
The research was led by the ARC-Net Research Centre of the University Hospital of Verona, Italy, with significant contributions from Glasgow University, and was published yesterday in Nature magazine.
Scientists looked at neuroendocrine tumours (NETs), specifically those which are found in the pancreas (PaNETs), the most common form of this rare cancer – it is the form of cancer that caused the death of Apple’s guiding genius Steve Jobs.
Researchers found that there were a significant number of inherited mutations in this type of cancer – 17 per cent of PaNETs cases looked at were linked to inherited faulty genes. Previously it was thought only five per cent of tumours were linked to hereditary genes.
Research leader Professor Aldo Scarpa said: “By sequencing the genome of these tumours we have decrypted the landscape of genetic alterations of these tumours. This discovery will allow us to target the development of specific therapies that aim to counter the alterations identified.”
Professor Andrew Biankin, the Glasgow University’s Regius Chair of Surgery and Director of the Translational Research Centre, said: “This study is a great example of International Team Science under the auspices of the International Cancer Genome Consortium.
“One of the most provocative findings is that these cancers had a larger than expected inherited gene defect that likely contributed to their development, potentially raising challenges in the clinic and refocusing future studies in the area.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
