SLN and muscular dystrophy: Notably, forced FRAIL1 expression also increased the abundance of mRNA encoding Sarcolipin (Sln), which is upregulated in immobilization‐induced muscle atrophy (Tomiya et al., 2019) and contributes to muscle wasting in models of muscular dystrophy (Niranjan et al., 2019; Schneider et al., 2013; Voit et al., 2017).
