Calcium-related abnormalities in fast and slow denervated skeletal muscle in rats
Abstract:
Muscle weights, Ca-ATPase activity and calcium-binding proteins were studied after denervation in rat extensor digitorum longus (EDL) and soleus (Sol) muscles. Muscle weights decreased progressively as a function of denervation time: after 28 days EDL weight diminished by 70% and Sol weight by 47%. Ca-ATPase activity and calsequestrin were quite reduced in control Sol as compared to the control EDL. Denervation caused a considerable reduction in Ca-ATPase and calsequestrin in EDL, making it resemble the control Sol.
