scientists at the Medical Faculty of the Christian-Albrechts-University Kiel (CAU) have confirmed that the life expectancy of humans by genetic factors.
Some 400 DNA samples from German centenarians had revealed that compared to younger ones, often have a variation in the gene FOXO3A.
in September 2008, an American research team published a study that suggested an accumulation of genetic variation in long Americans of Japanese descent (95 years and older).
"Such a result is only of scientific value if it is in an independent Study population is confirmed, "said Almut Nebel, scientific director of the Kiel-based research group of" healthy aging ".
The relationship between longevity and FOXO3A you can now have any doubts cleared. And French scientists in Paris had come to this conclusion. "This finding is of particular importance, as Japanese and Europeans are genetically quite different. Now we can assume that this gene is likely to reach a great age plays a role in the world, "said Nebel.
FOXO3A for genetic research on aging is of great interest, since it is in the 90s in worm and fly was described as age-relevant. Based on these findings, the Kiel-based research group at the Institute for Clinical Molecular Biology has been a long time with the human variant of the gene.
The study appears this week online in the journal PNAS (Proceedings of the National Academy of Sciences USA). © sc /
