Abstract: The present invention relates to a use of BAX inhibitor-1 for preventing or treating bone diseases. In the present invention, it has been first identified that the BAX inhibitor-1 gene is involved in osteoclast differentiation. It has been confirmed that, in animals in which the BAX inhibitor-1 gene is knocked out, osteoclast differentiation is increased, and femoral bone mineral density (BMD), corresponding to a goal index, trabecular bone thickness (Tb.Th), trabecular bone number (Tb.N), and trabecular bone volume (Tb.V) are all reduced compared to a wild type, and the spacing between trabecular bones (Tb.Sp) is wider than that of the wild type, resulting in worsened osteoporosis. Accordingly, the BAX inhibitor-1 can be advantageously used as a target molecule for the prevention or treatment of bone diseases, and it is possible to diagnose bone diseases by confirming deficiency, abnormal expression or dysfunction of BAX inhibitor-1. In addition, animals in which the BAX inhibitor-1 gene is knocked out can be advantageously used as animal models for bone diseases.
