40 YEARS OF IGF1: Role of IGF1 and EFN–EPH signaling in skeletal metabolism

Abstract excerpt

Insulin-like growth factor 1(IGF1) and ephrin ligand (EFN)–receptor (EPH) signaling are both crucial for bone cell function and skeletal development and maintenance. IGF1 signaling is the major mediator of growth hormone-induced bone growth, but a host of different signals and factors regulate IGF1 signaling at the systemic and local levels. Disruption of the Igf1 gene results in reduced peak bone mass in both...
