Abstract:Insulin‐like growth factor‐I (IGF‐I) facilitates mitotic and anabolic actions in all tissues. In skeletal muscle, IGF‐I can promote growth and resolution of damage by promoting satellite cell proliferation and differentiation, suppressing inflammation, and enhancing fiber formation. While the most well‐characterized form of IGF‐I is the mature protein, alternative splicing and post‐translational modification complexity lead to several additional forms of IGF‐I. Previous studies showed muscle efficiently stores… Show more
