Muscle atrophy; more than one string to MuRF1's bow?

The article focuses on a research study which examined the roles of two muscle-specific ubiquitin ligases, MuRF1 and MAFbx, in muscle atrophy. It outlines the mechanisms responsible for the loss of muscle protein content. It observes the role of both MAFbx and MuRF1 in the loss of muscle mass following dexamethasone administration.
