Lifespan of cells rises 82% in study

Using DNA editing, American researchers managed to create a method to give cells an 82% longer lifespan. The technique, called longevity engineering, can support future research into combating aging.

The discovery was published by researchers at the University of California, in the United States, in science magazine this Thursday (4/27). Molecular biologists claim that this is the first time that genetic change has succeeded in slowing down cellular aging at this level.

In the research, yeast cells were used, widely used in research due to their intense multiplication, but the researchers claim that the method could be replicated in human cells. “The cell reprogramming technique can be used in more complex organisms”, explain the researchers in the study.

In order to reverse cell aging, scientists created genetic circuits that allowed both the cell nucleus and its mitochondria to have their DNA transcription processes perfected — “recycling” prevents the accumulation of toxins.

“These results represent a breakthrough in the use of biological engineering to design synthetic genetic circuits that manage to control biological complexes such as aging”, says the editor of Science magazine, L. Bryan Ray.
