Activation of p38 during regeneration of cardiotoxin (CTX)-injured mouse soleus muscle. Total protein was extracted from soleus collected from wild-type (WT) mice on the indicated days after being injured by direct injection of 100 μl of 10 μM CTX. Western blot analysis was performed using antibodies that are specific for phosphorylated p38 or pan-p38. Average optical density (OD) data are expressed as the ratio of phospho-p38 to p38 and were assessed using ANOVA.
