| Outline of Final Research Achievements |
Receptor activator of NF-kB (RANK) is a member of the TNF receptor family expressed in osteoclast precursors, and RANK-RANK ligand signaling is essential for osteoclastogenesis. We have identified a novel alternative splicing variant of RANK gene (vRANK) encoding the short molecule. When overexpressed in vitro, vRANK in RAW264.7 cells decreased the formation of osteoclasts. When systemically overexpressed in vivo, the CAGcre+/vRANK mouse showed high fatality. When selectively overexpressed among the monocyte-macrophage lineage, the LysMcre+/vRANK mouse showed decreased osteoclastogenesis in ex vivo culture of spleen cells, and increased bone mass measured by micro CT. These results suggest that vRANK is a novel bioactive peptide that might educes the number of osteoclasts
