Blood detection of the length of telomeres can tell the age of DNA
Telomeres are a structure at the end of a chromosome that is essential for maintaining the stability of the human genome. In recent years, scientists have published a number of studies related to telomere length and aging. In 2009, the Nobel Prize in Physiology or Medicine was awarded to three scientists, Elizabeth Blackburn, Carol Greider, and Jack Szostak, for their discovery of the mechanisms by which telomeres and telomerase protect chromosomes. Earlier, Elizabeth Blackburn said in an interview that the nature of telomeres, like chromosomes, is a DNA sequence. For example, telomere is like a "plastic cover at both ends of the shoelace" to ensure that the shoelace does not loosen. But telomeres themselves have a long life. It is called the "life clock". Once the cells are split, the telomeres are shortened once. When the telomeres can no longer be shortened, the cells cannot continue to divide and die. It can be said that the length of the telomere determines the life of the organism. Recently, according to foreign media reports, a company in Silicon Valley called Telomere Diagnostics said that they developed a test for $89 to calculate the "age" of DNA in cells and tell you how much aging is. The kit, called TeloYears, uses a drop of blood sent by a user from home to detect the length of the telomeres. The user's telomere length will be compared to people in other age groups. However, it is worth noting that even in people of the same age group, telomere length varies greatly. Titanovo, based in North Carolina, has also developed a telomere test that sells for $150 and uses saliva samples.
