Scientific team found that the process of cancer cells influences the physical and chemical properties of DNA, so a test can detect cancer from the analysis of a small amount of DNA from the patient.
A team of scientists at the University of Queensland, Brisbane (Australia), has developed a test that ten minutes can detect cancer cells and make an initial diagnosis faster.
The research, published in the journal Nature Communication, has served to analyze the differences in DNA between cancer cells and those that are not damaged.
In all adult human cells, DNA caries modifications are established by a process called methylation which is genetically programmed, so the genomic information in cancer cells is significantly different from that in healthy cells.
The team conducted by studying Math Troo that the difference in the mucilation process of cancer cells influences the physical and chemical properties of DNA.
Scientists used the different behavior to develop a test that allows cancer to be detected from the analysis of a small amount of Dan patient.
This test only lasts about ten minutes and its result can be seen in a glance.
The test was carried out with 103 human DNA samples, of which 72 belong to people with cancer and 31 are of healthy people.
The researchers noted that, for the moment, in this stage of development, it can only detect the presence of cancer cells, not their type or the stage in which the disease was found and that it would be necessary to analyze more samples in Order to achieve a more detailed analysis. .
