Can detect 5 types of cancer at the same time with just one drop of blood

Currently, the list of these cancers has been revealed: colon, lung, breast, stomach and uterus.

Scientists at the US Institute of Human Genetics Research (NHGRI) have discovered a common genetic expression in the DNA of five different types of cancer cells, from which they propose a method of discovery. soon these diseases only by testing 1 drop of blood. Currently, the list of these cancers has been revealed: colon, lung, breast, stomach and uterus.

This result comes after the team discovered a chemical modification process of DNA called methylation . The process was identified by scientists as playing an important role in controlling gene expression. Since then, they have discovered a gene called ZNF154 that is directly linked to the development of tumors in the body.

The project leader, biologist Laura Elnitski , said the study on ZNF154 has been carried out by NHGRI since 2013 when they suspect this is the universal biological marker of many cancers. In addition, Larura It was also revealed that the entire research team was awake at night, confirming their ability to detect many types of cancer thanks to the ZNF514 gene code.

To detect traces of cancer within the body, the team used a genetic technique called polymerase chain reaction to amplify DNA from tumors and analyze the results, finding the concentration of ZNF154. on different types of tumors because each type of cancer will have a number of distinct signs of ZNF514. Dr. Laura himself admitted that selecting through a large amount of genetic data to find signs is not easy, but when " isolating search targets is actually making a breakthrough. breaking after a lot of efforts of the entire research team ".

In addition to the 5 cancers listed above, scientists have now embarked on an understanding of the relationship between ZNF514 and other forms of cancer such as bladder, breast, colon, pancreas and gland. paralysis. Blood samples from patients with these tumors are being studied thoroughly. In addition, some members of the research team also turned their attention to ovarian cancer of many women, especially those who have the ability to relapse.

In fact, Dr. Laura Elnitski also acknowledged that she and her colleagues still do not fully understand the relationship of methylation with cancer. Currently, scientists have questioned the origin of this link as a deflection in the development of normal cells, or this is a form of gene expression that reflects the growth of tumors in the body.

Whatever it is, this discovery has actually made a big step forward in early detection of cancers through the testing of 1 drop of blood . Currently, detectable forms of cancer have reached number 5 and will definitely increase in the near future. We will be waiting for new answers in the future.
