Protein content of (A) MuRF1, (B) 19S, (C) α7 and (D) β5 in control, 7 day or 14 day soleus muscle.

<p>Content of each protein was determined using Western blot analysis, normalized to the control muscle and set at 1.0. Pictured above the graphs are representative Western blots for each protein with arrows indicating molecular weight standards. All lanes were loaded with an equal amount of total protein (25 μg). Control was innervated muscle, 7 day was denervated for 7 days and 14 day was denervated for 14 days. Sample size per group, n = 5–7. Values are mean±SEM. *Significantly different from control (p≤0.05). ^#Significantly different from 7 day (p≤0.05). A.U., arbitrary units.
