Core Tip

Core tip: Current treatment of osteoporosis is based mainly on inhibiting bone resorption or stimulating bone generation to increase bone mass; however, the side-effects of some drugs affect long-term administration and adherence. There is still a lack of effective preventive or therapeutic method for radiation-induced bone injury. Because of the contribution of adipocytes to osteoporosis, future drug screening should target not only the regulation of the balance between bone formation and bone resorption but also the balance between osteogenic and adipogenic differentiation. Here, through screening, we identified five CR6-interacting factor-1 inhibitors targeting CR6-interacting factor-1-protein kinase cyclic adenosine monophosphate-activited catalytic subunit alpha interaction interface that could dramatically reduce receptor activator of nuclear factor κB ligand secretion and adipogenesis. Our study provides insights into potential therapeutic strategies for radiation-induced bone injury.
