Receptor Activator of Nuclear Factor-κB Ligand Activates Nuclear Factor-κB in Osteoclast Precursors*

Abstract excerpt

Receptor activator of nuclear factor-kappa B ligand [RANK ligand (RANK-L)] stimulates mature osteoclasts to resorb bone, a process associated with NF-kappa B activation. RANK-L also prompts macrophages to develop the osteoclast phenotype. Although NF-kappa B is essential for osteoclast differentiation, it is not known whether RANK-L activates this transcription complex in osteoclast precursors. We report that...
