• Elevation of intracellular calcium ions may be partly induced by increased influx through sarcolemma l type-calcium channels . intracellular calcium elevation, on one hand, would activate calpain, a calcium-dependent cysteine protease that degrade the myofibrillar proteins and cause muscle atrophy; on the other hand, result in activation of calcineurin which enhance the activity of mhc i promoter and inhibit a shift of mhc isoforms from slow to fast in soleus
