Xinhua News Agency, London, January 15 (Reporter Zhang Jiawei) The University of Edinburgh in the United Kingdom released a study on the 15th that by analyzing DNA (deoxyribonucleic acid) information, it is theoretically possible to predict whether a person will live longer or shorter than the average life expectancy. . However, there are also points of view that life expectancy is also affected by other factors such as the environment.
The team led by researchers at the University of Edinburgh reported in the Journal of Electronic Life that they analyzed the genetic information of more than 500,000 people and the life records of their parents, confirming 12 regions of the human genome that have a significant impact on longevity. Five of these areas have not been reported before. The study found that the most significant impact on longevity was the area of ​​the gene associated with deadly diseases such as heart disease.
Based on the above findings, the research team produced a scoring system to assess life expectancy. One of the authors, Peter Josh of the University of Edinburgh, explained that if you find 100 newborn babies and divide them into 10 groups using this scoring system, then the highest scoring group is expected to live an average of 5 more years than the lowest scoring group.
Some people believe that in addition to genetic factors, there are other factors that affect the life span of human beings, such as the environment. The researchers said that they only gave an evaluation attempt, and it does not mean that it can clearly judge the length of life of a person.
The researchers also hope to find genes that directly affect people's aging rate, but no relevant evidence has been found in this study. Next, they plan to expand the scale of their research, hoping to find the key genetic mechanisms that lead to aging and disease.
