Daniil Cohan, director of the French Institute of Human Polymorphism and author of the book Hope Gene, said: "It won't be long before the new gene technology will find a biological way to make human beings live to be over 1000 years old."
Cohen said: "This is not to say that we scientists have discovered the secret of immortality and youth, let alone trying to make our life span exceed the limit of about 120 years stipulated in the biological timetable, but trying to make everyone live to be old and have the ability to act."
Experts unanimously pointed out that if there is any secret to longevity, it is in our genes.
After years of failure and a lot of research work, biologists have seen the dawn and found some basic methods to solve this problem.
In this research process, they used thousands of flies to study the genes of centenarians and mastered the genetic code of insects.
Many international scientific research groups have studied Drosophila melanogaster for many years, among which the research group led by Rajindar Sohall and William Orr of Southern Methodist University in Dallas, USA, has achieved the most outstanding results.
These geneticists mastered several Drosophila families from the perspective of genes a year ago, and enabled these Drosophila to increase the production of longevity enzymes. The results of the study are very surprising. The life span of these fruit flies has been extended by 30%.
These studies do not rule out that this technology may also extend the life span of higher animals, including humans.
At present, the most common view about the process of human cell failure is that our body produces 654.38+000 billion charged molecules every day. These charged molecules are called free radicals. They penetrate the cell membrane, destroy the fragments of genetic material and start a series of destructive reactions in the body.
Another hypothesis about human aging is that glucose combines with some protein in the body to produce a by-product called AGE, which will gradually destroy the DNA in cells.
Sochor said: "Through experiments, we believe that the theory of liberal radicals is valuable."
The method used by Sochor and Orr seems simple. They just implanted two genes responsible for producing antioxidant enzymes (superoxide dismutase and catalase) into Drosophila.
Results The life span of Drosophila family with two antioxidant enzymes was prolonged by 30%. In the experiment of gorillas, scientists also found the proportional relationship between the production of superoxide dismutase in the body and its life span.
Michael ross, a well-known insect longevity expert at the University of California, said that if money is invested in the research of human longevity, "I think in the next 25 years, we will become witnesses in manufacturing products that extend human life."
