INOV :
Métabolisme du cholestérol et
innovations thérapeutiques
Les spécificités
de notre axe de recherche
Nous explorons le rôle du métabolisme du cholestérol dans le contrôle de la progression tumorale et dans la résistance aux thérapies dans plusieurs cancers (sein, peau, thyroïde, leucémies). Nous étudions les propriétés biologiques et les voies de biosynthèse de deux métabolites que nous avons découverts: la dendrogénine A (DDA) et l’oncostérone (OCDO) qui sont respectivement des métabolites suppresseur et promoteur de tumeurs. Ces études ont pour but ultime le développement de nouveaux candidats médicaments et d’outils théranostiques pour de nouvelles thérapies ciblées et personnalisée des cancers. Elles permettront en outre de définir le rôle de la composante stérol de l’alimentation sur le développement de certains cancers.
