Abstract

L'invention concerne des méthodes, des compositions pharmaceutiques et des trousses permettant de moduler l'activation du précurseur du muscle squelettique. Pour effectuer cette modulation, on utilise du monoxyde d'azote (NO), des donneurs de NO, des inhibiteurs d'activité du NO (inhibiteurs de NO) ou des régulateurs de production de NO, soit au niveau local, soit au niveau systémique. L'invention concerne également l'utilisation de NO, d'un donneur de NO, d'un inhibiteur de NO ou d'un régulateur de production de NO afin de moduler les effets des stéroïdes hormonaux sur le muscle squelettique. L'invention concerne également une méthode permettant d'identifier un composé qui provoque un changement de l'état d'activation des précurseurs du muscle. L'invention apporte un certain nombre d'avantages évidents. En permettant de manipuler directement les précurseurs du muscle squelettique, l'invention permet d'élaborer des traitements spécifiques afin de régénérer et de réparer le muscle.
