Degradation of the myofibrillar protein and the glycolytic enzyme among the muscle proteins of sea bass (Dicentrarchus labrax) could be observed clearly during storage (Terova et al.
Isoform switching in myofibrillar and excitation-contraction coupling proteins contributes to diminished contractile function in regenerating rat soleus muscle.
However, the contribution of muscle protein to wholebody protein metabolism was significantly reduced in the elderly, and explained by their reduced muscle mass and lower rates of myofibrillar protein turnover.
IGF-I is also involved in numerous anabolic and catabolic events in skeletal muscles, such as the aggregation of myofibrillar protein by combination of the effects on protein synthesis and degradation (COLEMANN et al.
