Events: United States successfully reversed the aging process will help develop mouse elixir of life (Figure
| Event Details:
This is a 2008 science fiction Juxian "youth" in the picture, starring Brad Pitt played a violation of natural law, created to the elderly, the longer the odd corner of the young Benjamin Button, and Oscar with this role nomination.
Beijing November 30 message, U.S. scientists recently passed rat study, the first successful reversal of the aging process, which is developed a "eternal youth" paves the way drugs. The study, by Harvard University's Ronald Durbin Hall oncologists conducted related research published in the authoritative journal "Nature" magazine.
Before carrying out tests, the animals skin, brain, internal organs and other organs with a similar 80-year-old man. To them to open a key enzyme taking the drug only 2 months later, these animals grow a large number of new cells, they are almost thoroughly updated, has been rejuvenated by. More surprising is that male mice can escape that maternal pregnant again, raising a large number of offspring.
If the use of the study, the scientists developed a "eternal youth" drugs, people can live longer, healthier, and will not be Alzheimer's disease and heart problems, skin and hair as shiny as the young bright. The drug may also make men and women in old age had previously been able to have children naturally. Increase the healthy life of the time but also can greatly reduce the cost of health services, family support to reduce the burden of frail relatives.
De Binhuo said: "This is like a 40-year-old who looks like a 80-year-old, after a downturn in his 50-year-old level. By 2025 we will have 1.2 billion over the age of 60 years old, this age people began to susceptible cancer, Alzheimer's disease and cardiovascular disease. we are about to face the heavy social burden. This trial is the first time we successfully reversed the aging process. This shows that there is a reversal of aging organ point is that we have never realized The. "
This major breakthrough in mainly focused on telomere structure. These are covered in the chromosome ends, preventing them from damage to the micro-clock. Over time, telomeres get shorter, which increases the risk of age-related diseases such as Alzheimer's risk. Until they become too short, the cells die. Telomere telomerase reverse transcriptase can recycling, but the body will tend to turn off this enzyme.
De Binhuo through a special method of premature aging in mice to simulate the human aging process, and then stimulate the use of drugs, the success that telomerase reverse transcriptase back to life. He hopes that this technology can terminate or slow down the aging process, found it and reverse it is a surprising thing. He believes that eventually should be able to develop a human body can produce the same effect of the drug. Take the middle-aged, this drug can delay or prevent dementia, heart disease and diabetes, and even prolong life.
But people should also pay attention to: high levels of telomerase reverse transcriptase can accelerate tumor growth, one drug alone can not remove all the old problems. De Binhuo said: "aging is caused by a variety of common mechanisms. Thus, while we believe that telomeres are important, but there are other factors also play an important role." Telomere Zhuanjia Harvard University Steven Asia Dr. Tandy said the study "very nice", but he warned that an anti-aging drugs can only be reversed up to 10 years time. |
