Relative expression of desmin and myosin light chain (MLC) mRNAs in plantaris (A), soleus (B), and gastrocnemius muscles (C) from young adult and aged rats after RT-PCR amplification. The expression of each PCR product was normalized to the cyclophilin signal from the same RT product. Values are means and error bars represent SEs (n = 10/group). *Data from aged rats were significantly different from young adult rats in the same muscle at P < 0.01.
