Scientists Reverse Aging in Mice
Scientists said they may be able to turn back time, and reverse the aging process -- in lab mice, at least.
The Salk Institute in La Jolla, California, reported its team was able to rejuvenate the organs of mice and lengthen their life expectancy by 30 percent through genetic engineering.
While this type of genetic engineering cannot be applied to people just yet, the finding could help experts better understand human aging with the hopes of rejuvenating human tissues, the New York Times reports.
“It’s a pretty remarkable finding, and if it holds up it could be quite important in the history of aging research,” said Leonard Guarente, who studies aging at MIT, the New York Times reports.
Salk Institute’s Juan Carlos Izpisua Belmonte had been interested in regeneration in certain animals like lizards and starfish after several failed studies done by other scientists to reset the biological clock.
By applying four different types of genes, called Yamanaka genes, to mice two times a week.
“What we saw is that the animal has fewer signs of aging, healthier organs, and at the end of the experiment we could see they had lived 30 percent longer than control mice,” Izpisua Belmonte said.
Izpisua Belmonte said he will be testing drugs to see if he could achieve rejuvenation that could have the same effect as the Yamanaka genes.
