The increase in skeletal muscle mass induced by clenbuterol is eliminated by ablation of β-arrestin 1. Muscle weight normalized by tibia length for EDL (a), soleus (b) and plantaris (c) were present from WT and βarr1KO mice after 4 weeks treatment of vehicle or clenbuterol (1 mg/kg/day). Normalized muscle index was presented as a fold increase over vehicle stimulation. Means ± SEM are shown from 7 to 8 mice per group. Statistical comparison was performed by using a two-way ANOVA with Tukey’s multiple comparison test (***, P < 0.001)
