Activin is a known physiologic regulator of bone metabolism. Ovariectomy-induced osteopenia has been shown to be attenuated by injection of the activin type IIA decoy receptor (ActRIIA-Fc). However, immobilization-induced osteopenia is driven by different pathways than ovariectomy-induced osteopenia, and the role of activin in immobilization-induced osteopenia has not yet been elucidated.The purpose of the study was to investigate the possible attenuatio...
