| Research Abstract |
We clarified a part of molecular mechanisms on bone volume regulation by analyzingFbxo32 knockout mice. By bone morphometric analysis after mouse tail suspensionexperiments, it appeared that Fbxo32 gene expression in osteoblasts was associated with the bone volume but not bone density in the bone formation. Further, wild type mice and Fbxo32 knockout mice were administered isoproterenol, similar morphometric value between the femurs was recognized, indicating that Fbxo32 was not involved in a sympathetic nerve-stimulated decrease of bone volume.
