Researchers at the University of Queensland Australia have developed a technique that can detect all cancers through a simple blood test. The researchers, who published their study in Nature Communications, said they discovered a test-specific "DNA nanoparticle." They added that cancer was a complex and variable disease, and that it was always difficult to find a single common fingerprint of any kind, different than that of healthy cells in the body. The researchers therefore focused on a method called "free rotary DNA" test.
Scientists have studied nano-genotypes (nano-1 billion units) in the genome of cancer cells and healthy cells, with the aim of verifying the formation of molecules in the "methyl groups" that frame the cells. DNA "He said." Although methyl groups are spread throughout the genome in healthy cells, researchers have found that the genome of cancer cells is very poor, with the exception of a concentrated contract of these methyl groups present in specific regions.The only sign of cancer is the presence of these groups in bad cancer profiles and in all other cancers, including prostate, colon, rectum and lymphoma. The researchers therefore designed gold nanoparticles to change color when there were parts of the DNA, tested 200 blood samples from different cancers and healthy cells, the accuracy of the test was 90%. .
Dr. Abu Sina, co-author of the study, said that this discovery could lead to new methods for rapid diagnosis of the disease.
