Study finds that various cancers share the same ‘DNA signature.’
A team at the University of Queensland in Australia has discovered that DNA fragments from cancer cells adopt a unique structure in water.
From these results, they developed a test that can detect the apparently universal cancer DNA signature in less than 10 minutes.
They also demonstrated that the test was up to 90 percent accurate over 200 samples of tissue and blood.
Higher accuracy in a test means that it produces fewer false positives, which are results that suggest that cancer is present when it is not.
The journal Nature Communications has now published a study paper about the test and how the scientists developed it.
‘Simple universal marker of cancer’
Should it prove effective in human trials, the test could mark the end of a long search for a single diagnostic tool that works for all types of cancer.
“We certainly don’t know yet,” says senior study author Matt Trau, who is a professor of chemistry, “whether it’s the Holy Grail or not for all cancer diagnostics, but it looks really interesting as an incredibly simple universal marker of cancer.”
