Abstract

Background: Osteocyte apoptosis precedes bone loss induced by reduced mechanical forces, and unloading increases RANKL expression. Results: Inhibition of osteocyte apoptosis prevents increased osteocytic RANKL but not bone loss induced by tail suspension. Conclusion: Prevention of apoptosis and reduction of osteocyticRANKLare not sufficient to stop unloading-induced bone loss. Significance: RANKL from non-osteocytic sources contributes to bone loss induced by reduced mechanical forces.
