Insulin-like growth factor-1 (IGF-1) is a multipotent growth factor involved in the growth, development and regulation of homeostasis in a tissue-specific manner. Alternative splicing, multiple transcription initiation sites and different polyadelynation signals give rise to diverse mRNA isoforms …

OBJECTIVE: Preferential IGF-1Ec expression has been firmly associated with skeletal muscle repair mechanisms, post-infarction remodeling of the myocardium, the pathophysiology of endometriosis and prostate cancer biology. Therefore, we have studied the possible biological significance of synthetic Ec peptide, a putative cleavage product of IGF-1Ec in PC-3 cells and C2C12 myoblasts …
