Abstract excerpt
Signaling through the IGF-I receptor by locally produced IGF-I or -II is critical for normal skeletal muscle development and repair after injury. In most tissues, IGF action is modulated by IGF binding proteins (IGFBPs). IGFBP-5 is produced by muscle cells, and previous studies have suggested that when overexpressed it may either facilitate or inhibit IGF actions, and thus potentially enhance or diminish...
