Effect of denervation on the content of cardiac troponin-T and cardiac troponin-I in rat skeletal muscle

There was no significant difference in cTnI content between the fast EDL and slow soleus muscles. The cTnT content was significantly higher in the soleus than the EDL muscle (p < 0.001). These data, combined with data on other models in the literature, indicate that re-expression of cTnT and cTnI isoforms in adult skeletal muscle is unlikely and does not interfere with cTnT assays for assessment of cardiac damage.
