Une \u00e9quipe de chercheurs internationale sugg\u00e8re d\u2019utiliser le g\u00e9nome du renard pour mieux comprendre la base g\u00e9n\u00e9tique du comportement des mammif\u00e8res (chiens et hommes notamment).
\nR\u00e9troactes : en 1959, des scientifiques russes ont commenc\u00e9 \u00e0 \u00e9lever des renards roux afin de les apprivoiser. Parall\u00e8lement, ils ont \u00e9galement \u00e9lev\u00e9 un deuxi\u00e8me groupe de renards, favorisant leur agressivit\u00e9. Ce programme de s\u00e9lection \u00e0 long terme est devenu c\u00e9l\u00e8bre sous le nom de \u00ab Russian farm-fox experiment \u00bb et a conduit \u00e0 d\u00e9velopper des ph\u00e9notypes comportementaux tr\u00e8s diff\u00e9rents chez ces renards.
\nR\u00e9cemment, cherchant \u00e0 comprendre quels g\u00e8nes sont \u00e0 la base de diff\u00e9rents comportements sociaux, des chercheurs am\u00e9ricains, russes, chinois et danois ont assembl\u00e9 le g\u00e9nome du renard roux et l\u2019ont utilis\u00e9 pour comparer les s\u00e9quences g\u00e9n\u00e9tiques des lign\u00e9es de la c\u00e9l\u00e8bre ferme russe.
\nCes scientifiques ont trouv\u00e9 103 r\u00e9gions g\u00e9n\u00e9tiques diff\u00e9rentes entre les populations, y compris certaines r\u00e9gions connues pour \u00eatre li\u00e9e \u00e0 la domestication chez le chien.
\nUne de ces r\u00e9gions comprend un g\u00e8ne appel\u00e9 SorCS1. Chez l\u2019homme, les alt\u00e9rations de ce g\u00e8ne sont associ\u00e9es \u00e0 l\u2019autisme et \u00e0 la maladie d\u2019Alzheimer. Mais chez les renards, les modifications semblent dicter si le renard est apprivois\u00e9 ou agressif.
\nLes chercheurs pensent que le renard repr\u00e9sente un puissant mod\u00e8le d’analyse g\u00e9n\u00e9tique des comportements domestiques et agressifs pouvant \u00eatre utiles aux \u00e9tudes g\u00e9n\u00e9tiques sur le comportement des chiens et d’autres mammif\u00e8res, y compris l’homme.
