A new research conducted by researchers at the Stanford University has determined that genes can tell how much you live. This conclusion was drawn after scientists compared the genes of people, who lived for approximately 100 years.
Scientists have long sought for the secret ingredient to a longer healthier life. Important progress was made in the past years due to new research. In addition to healthy food and products that people can eat to remain healthy for a long period of time, physical condition also plays an important part.
Stanford researchers have studied the subject of longevity for decades. They have come to the conclusion that genes, too, can determine how long a person will live. As a consequence, they have gathered a large group of long-living participants, 800 centenarians and 5,400 nonagenarians.
The medical analyses of the participants have revealed that four particular genes are responsible for longevity. To be more specific, the ABO gene is related to the blood type of a person and the CDKN2B gene is extremely important for cell division. Similarly, the APOE gene can estimate a person’s tendency towards Alzheimer’s and the SH2B3 gene can prolong a person’s life much in the same way it does for fruit flies.
The influence of the said genes was evaluated once again at the end of the experiment, during a follow-up study of 1,000 centenarians. Based on these two tests, researchers have concluded that the four genes can determine a person’s life length.
These genes can dictate whether a person will develop a specific health problem at some point in life. People with ABO genes are less likely to suffer from heart diseases and cardiac arrests, one of the major causes of deaths in the United States.
As for the CDKN2B gene, the research has proven that participants with such gene variation presented slower aging processes. The presence of this gene plays a major role in the fight against cancer. Cancerous formations usually appear during an abnormal functioning of the cells; therefore, the CDKN2B gene can be a life saver.
In the end, the study has proven that people need all these four genes to remain healthy – the first condition for a longer life. According to Stuart Kim, the author of the study and a professor of Developmental Biology and Genetics at Stanford University, the newly identified group of four genes can prevent illnesses. More research will be made in the field in the future.
