DNA that causes cancer could one day be SNIPPED out of people’s bodies – thanks to amazing new breakthrough

In In The News by Barbara Jacoby0 Comments

By: Miriam Stoppart From: mirror.co.uk There always has been good news about cancer, but often it’s ignored or not shouted about. Well, I’m going to be shouting. One of the fascinating innovations I’ve been following for some time is CRISPR technology that can act as tiny molecular scissors and cut out damaged and sometimes cancer-promoting bits of DNA . It’s …

‘Exciting’ blood test spots cancer a year early

In In The News by Barbara Jacoby0 Comments

By: James Gallagher From: bbc.com Doctors have spotted cancer coming back up to a year before normal scans in an “exciting” discovery. The UK team was able to scour the blood for signs of cancer while it was just a tiny cluster of cells invisible to X-ray or CT scans. It should allow doctors to hit the tumour earlier and …

Researchers at the Gene Editing Institute at Christiana Care Health System develop new system to perform precise ‘surgery’ on the human genome

In In The News by Barbara Jacoby0 Comments

Molecular biologists at Christiana Care Health System’s Gene Editing Institute have developed a new system that allows them to not only repair damaged DNA within human cells, but also to determine when the DNA repair machinery has introduced unwanted genetic changes alongside, or instead of, the desired repair. A team of researchers led by Eric Kmiec, Ph.D., director of the …

Johns Hopkins researchers develop new, highly accurate urine test to predict risk for cervical cancer

In In The News by Barbara Jacoby0 Comments

Source: John Hopkins Medicine From: news-medical.net Johns Hopkins Medicine specialists report they have developed a urine test for the likely emergence of cervical cancer that is highly accurate compared to other tests based on genetic markers derived directly from cervical tissue. The new urine test, they say, is different because it analyzes not only multiple sources of human cellular DNA …

Gene may worsen cancer outcome by speeding metabolism of drugs

In In The News by Barbara Jacoby0 Comments

Institute Cancer Research From: eurekalert.org Some patients with breast cancer, lung cancer and leukaemia seem to fare poorly after treatment because of the effects of a particular gene, a new study finds. The gene, called CYP3A7, is normally only active in infancy, but in some people it continues to be switched on into adulthood, and over-activates their metabolism. Adults with …

Are We Ready for a Blood Test for Cancer?

In In The News by Barbara Jacoby0 Comments

By Nicholas Weiler From: ucsf.edu What if screening for cancer was as easy as checking your cholesterol? That’s the promise of techniques currently in development that may one day make it possible to detect the earliest stages of cancer with an annual blood draw. So-called “liquid biopsies” involve extracting free-floating cancer cells or cancer DNA from the bloodstream (or in …
