If, your doctor suspects you have cancer of the colon, stomach, breast and uterus. In the future you will no longer need to go through painful and time-consuming tests. It will be enough to give blood.
What have found the scientists
Experts have identified the most common genomic signature in the DNA of tumor cells. It turned out that five different kind of war has almost identical genomic signature. This discovery could lead to far the best way to diagnose many types of cancer in their working stage.
Scientists believe that the simple blood test will be sufficient for an accurate diagnosis. The thing is that in the presence of cancer comes from chemical changes in DNA methylation is the name, and it controls the expression of certain genes.
When the bio-markers identified methylation, scientists found identical pattern in five different types of tumors such as colon cancer, lung cancer, stomach cancer, breast cancer and uterine cancer.
– The discovery of a single methylation signature was crucial and it will help us a lot in the correct diagnosis. It took us a while to find it, and before us was a huge technical challenge. But we found this signature methylation around the ZNF154 gene, which is unique to tumors. No one on my team could not sleep after the important discovery, as far as we were excited. This is the first time that we have found such a pattern that is applicable to many types of cancer – explains biologist Laura Elnitski the US National Human Genome Research Institute.
Earlier diagnosis of cancer would greatly contributed curability and a large reduction in mortality from cancer.
