Aging is an inevitable rule in the process of human life. Deepening wrinkles, flabby skin, horizontal eye bags and frequent spots are just superficial phenomena of aging, including malignant tumors, cardiovascular and cerebrovascular diseases diabetes And other chronic diseases will be accompanied by aging. For thousands of years, scientists all over the world have been exploring the mystery of human aging. What factors affect the aging trend of the human body?
Tong Tanjun, academician of the Chinese Academy of Sciences, said that human aging is mainly affected by heredity, environment, cell genes and other factors. He introduced that there is a maximum life span for all kinds of animals, which is determined by genetic factors. At the same time, the environment has a profound impact on aging. The environment here includes the external environment and the internal environment. For example, air quality, water quality, etc. belong to the external environment, while the internal environmental system of the human body will also have a significant impact on life span. In addition, if most of the important cells in the human body are healthy, then the life span of people will be correspondingly longer.
Tong Tanjun believes that P16 gene is closely related to cell aging. After long-term dedicated research, he led the team to solve the mystery of human cell aging, and clarified that P16 gene is the leading gene of human cell aging, and also the main factor of human cell aging genetic control program. "This gene guides the production of a protein with a protein score of 16000, which is called P16. P16 is a very important gene, which can slow cell division and is also a tumor suppressor gene. Later, it was found that this gene had a great relationship with cell aging. The older the cell, the more active it is. " In 2001, Tong Tanjun published two academic papers on cell aging and the regulation of P16 gene expression in the American Journal of Biochemistry. This achievement is an original contribution made by Chinese scholars in the research of human cell aging mechanism, and has attracted extensive attention from domestic academic circles and major media.
With the continuous development of science and technology, the mystery of human aging is being uncovered step by step. These new discoveries of aging laws provide a new vision for people to study aging and resist diseases. A new healthy future of "aging without aging, aging without disease" is worth our common expectation.
