American researchers have managed to extend 30% expectancy mouse life. They have, for that removed the cells related to the aging of their body by an enzyme.
Remove the body cells and pathologies that are old: it is the experiment conducted by a team of North American biologists to try to prolong life and delay aging.
Published in the scientific journal Nature on February 3, the study shows that mice that were used in carrying out these works have lived longer and healthier. To achieve these results, the researchers administered to "normal" mice for six months, every two weeks, an enzyme (already used on genetically modified mice in the early 2000s) destructive senescent cells (related aging). After the experiment, Nathaniel David's team compared these animals to other witnesses rodents. The mice tested are generally appeared healthier. They indeed show better renal function, a more stress-resistant heart and a developmental age of later cancers. They even lived longer than other rodents witnesses with estimated life of between 20% and 30%.
Scientists point out, however, that all the bodies have not responded favorably to treatment with the enzyme. The liver and colon in particular have shown "refractory to treatment." More surprisingly, the healing time in treated animals proved longer than the control mice.
Although this study is not the first to do live mice longer, it is however the first time that work targets senescent cells. If we knew that life expectancy could be extended by modifying our diet or our lifestyle, this new method is actually the first to attack the cells responsible for aging.
The question is whether this discovery may also apply to humans.
