Patent

CA 2599125

Provided herein are methods and compositions for modulating the activity of sirtuin deacetylase protein family members; p53 activity; apoptosis; lifespan and sensitivity to stress of cells and organisms. Exemplary methods comprise contacting a cell with an activating compound, such as a flavone, stilbene, flavanone, isoflavone, catechin, chalcone, tannin or anthocyanidin; or an inhibitory compound, such as a sphingolipid, e.g., sphingosine. Also disclosed herein are methods for treating, preventing or diagnosing a disease associated with neuronal cell death, e.g., a neurodegenerative disease.

L'invention concerne des méthodes et des compositions permettant de moduler l'activité de protéines membres de la famille des désacétylases sirtuines, l'activité de la protéine p53, l'apoptose, la durée de vie et la sensibilité au stress des cellules et des organismes. Ces méthodes peuvent consister par exemple à faire entrer en contact une cellule avec un composé d'activation tel qu'une flavone, un stilbène, une flavanone, une isoflavone, une catéchine, un chalcone, un tanin, ou une anthocyanidine, ou un composé inhibiteur tel qu'un sphingolipide, p. ex. la sphignosine. L'invention concerne en outre des méthodes permettant le traitement, la prévention ou le diagnostic d'une maladie liée à la mort des cellules neuronales, telle qu'une maladie neurodégénérative.
