Research Abstract |
We identified GDF15 as an endocrine factor secreted from osteocytes. Recombinant GDF15 significantly promoted osteoclastic differentiation. The anti-GDF15 antibody prevented bone loss through inhibiting osteoclastic activation in tibias from mice with femoral artery ligation in vivo. These findings suggest that GDF15 could play a pivotal role in the pathogenesis of bone loss relevant to hypoxia through promotion of osteoclastogenesis after secretion from adjacent osteocytes during disuse and/or ischemia in bone.
