(BOSTON) -- Scientists have found that by tweaking the genes of mice, they are able to slow, or even reverse the process of aging. With just a few changes, the animals were able to regenerate brain cells, and their fertility was able to be restored. Alternatively, mice aged prematurely when those changes were made in reverse order.
A report, published in the weekly online science journal Nature, shows that scientists hope similar results may be possible for humans down the road. The scientists who published the report, working out of the Dana Farber Cancer Center in Boston, worked with the chromosomes that are found inside the nuclei of all cells. By transforming the protective part of the chromosome, which guards the cell from diminishing, scientists could either accelerate, or reverse the aging process.
Some scientists say the study can be beneficial if the process eventually leads to cures for things like heart disease and diabetes, which become more debilitating with age.
So far the study has been restricted to mice.
