The drug rapamycin appears to have more less the same life flow effect as limiting calories, according to the great study, still of long life in various vertebrate species.
Researchers are investigating where as dietary adjustments and exercise can help us live alive and reduce the health effects of aging. It has been shown that the restriction of calorie intake, while ensuring that essential nutritional needs are transmitted, has been shown to extend the life of non -human animals by up to 40 percent.
“Anyone in the field who is aware, I think we have all known for a long time that calori restrictions work – and by works I mean increases the lifetime,” says Matt Kaeberlein at the University of Washington in Seattle, involved in recent research.
Another approach that gathers interest is potential anti-aging drugs, such as rapamycin, which was originally developed as an immunosuppressive agent. A combination of rapamycin and cancer trametinib was shown earlier this year to include life in mice by 30 percent.
Now Zahida Sultanova at the University of East Anglia, UK, and her colleagues have looked at data from 167 studies of life interventions across eight vertebrate species, including fish, mice, rats and rhesus -monkeys, but not human.
The researchers found that dietary limitation, whether through intermittent fasting or just generally, to cut calories, expanded the life of all eight species, for both men and women – and rapamycin seems to have some sense effect. They also look at the potential of type 2 diabetes drug formin, which has similarly been designated as a potential life release, but found no long life.
However, people should not start taking rapamycin from the back of these results, says Sultanova. “Rapamycin, especially high doses, has side effects because it needs to suppress your immune system,” she says, adding that Miche studies show that it can interfere with reproduction. Still, Prelimina data from an attempt recently indicated to make doses of rapamycin are relatively safe in healthy old adults.
Kaeberlein also says that people should not take any medication or limit their calorie intake in an attempt to avert aging, with the later associated with physical weakness and mental problems. “I think we now have to now have more about the risk-rewarding relationship in people before we can make these kinds of decisions,” he says. “I think rapamycin wants yefits for some people, and we learn more and more about who these people are likely to be.”
Other drugs that work similarly like rapamycin, known as rapalogs, could make more promise if they can extend the life with even my IFAL side effects, sultanova.
Kaeberlein says the results fit the patterns he has seen in the literature, but adds that “you must always be careful when you are across different species the size of effects that we see in shorter-living organisms are usefully larger than the size we see organizations”.
