A group of researchers has proposed a new way to slow down the aging process of living cells by manipulating DNA.
By studying the mechanisms of aging in yeast, scientists fromThe University of California, San Diego found that despite their genetic similarity and the same habitat, they can age in very different ways. About half of the studied cells died as a result of a gradual decrease in the number of nucleoli, while in others, mitochondria ceased to function.
After additional tests, the researchers found that cells start to follow one of two pathsfrom the very beginning of their life and identified the molecular contour that determines the type of aging. This allowed the team to model the process and optimize it by reprogramming the genetic code, which dramatically increased the life span of the yeast.
Scientists say that similar methods can also beapply to delay human aging and improve his health indicators. Therefore, in the future, they will conduct experiments with complex cells and organisms.</p>
