Cette 9ème chronique démarre avec 3 déesses de la mythologie grecque appelées les Moires et qui déterminent la destinée des hommes. Parmi ces 3 divinités, Clotho est la Moire qui tisse le fil de la vie des hommes. Cette chronique se poursuit par une surprenante découverte faite par des chercheurs japonais qui identifient en 1997 un gène dont la destruction dans une cellule œuf de souris provoque une forme spectaculaire de vieillissement prématuré. Et ces chercheurs vont donner à ce gène le nom de klotho. Depuis la découverte du gène klotho, de nombreuses études vont permettre de préciser les effets et le mode d’action de la protéine codée par ce gène. Klotho s’avère être non seulement une protéine de longévité, mais elle peut aussi favoriser le fonctionnement cérébral, retarder le développement des symptômes de maladies neurodégénératives et permettre de lutter contre certains cancers.

9. Biological Chronicles - From the Goddess Clotho who spins the web of life, to the discovery of a protein of youth.

Our chronicle begins with 3 goddesses from Greek mythology called the Moirai, the Fates, who decide the destiny of men. Among these 3 divinities, Clotho is the Fate who weaves the thread of life. This chronicle continues with a surprising discovery made by Japanese researchers in 1997 who identified a gene whose destruction in the cell of a mouse egg caused a spectacular form of premature ageing. They gave the gene the name of klotho. Since the discovery of the klotho gene, numerous studies have been able to specify the effects and the mode of action of the protein encoded by this gene. Klotho has been shown to be not only a longevity protein, but it can also promote brain function, delay the development of symptoms of neurodegenerative diseases and help fight certain cancers.
