Receptor activator of NF-κB ligand (RANKL) is a key factor in osteoclast differentiation that induces changes in the chromatin state of osteoclast precursors. However, the epigenetic mechanisms that regulate osteoclast differentiation have not been well clarified. Park-Min et al. report that the benzodiazepine derivative, I-BET151, a small-molecule inhibitor of BET proteins (which bind to acetylated histones and control gene transcription), suppresses RANKL-induced osteoclastogenesis and prevents bone loss in several mouse disease models. I-BET151 was shown to target a MYC–nuclear factor of activated T cells (NFAT) axis important for osteoclastogenesis.
