Figure 3: Pax7 and Pax3 expression in TA and SOL muscles of denervation and disuse models. The quantitative polymerase chain reaction expression of Pax7 in the tibialis anterior muscles for both groups remained constantly low (a). Pax3 expression pattern in the tibialis anterior muscles in both models rapidly increasing from the 1st week but declining from the 2nd week (b). The Pax7 expression in the soleus muscles of both models increased in the 1st week but decreased from 2nd week (c). Pax3 expression in the soleus muscles of both groups reached its peak in the 2nd week (d). The changes of Pax7 and Pax3 expression were summarized in a table (e).
