New research says somatic mutations accelerate aging

, Sept. 2 (Xinhua Zhang Jiawei) The University of Edinburgh announced a study on the 2nd, said that if the body appears soy cell mutations, will speed up the aging process, increase the risk of some diseases.
Researchers at the University of Edinburgh and others said in a paper published recently in the AMERICAN journal Current Biology that they analyzed data from a large study of more than 1,000 people who were surveyed at the age of 11 and are now in their 80s and 90s, and that the information could be used to analyse the factors that influence aging.
analysis showed that about 6 percent of them had changes in DNA (deoxybonucleic acid) that formed the day after, also known as somtic cell mutations. Unlike innate reproductive cell-related DNA changes, soytic cell mutations are not passed on to offspring, but have various physiological effects on them.
study found that people with soda cell mutations in their bodies were nearly four years older than those who did not have such changes and were similar in other ways. Physiological age refers to the age stage reflected in the physiological characteristics of the body, and the actual age is not necessarily consistent. Physiological age means aging is faster.
team believes that mutations in somatic cells affect the function of blood stem cells and are linked to conditions such as leukemia, which may be linked to accelerated aging.
Tamir Chandra of the University of Edinburgh, co-author of the report, said previous research on somatic cell mutations, mainly in cancer, showed that somatic cell mutations also play a role in other diseases and could change the way research is conducted.
