Lrp5 functions in bone to regulate bone mass.

The human skeleton is affected by mutations in Low-density lipoprotein Receptor-related Protein 5 (LRP5). To understand how LRP5 influences bone properties, we generated mice with inducible Lrp5 mutations that cause high bone mass and low bone mass phenotypes in humans. We conditionally-induced Lrp5 mutations in osteocytes and found that bone properties in these mice were comparable to bone properties in mice with inherited mutations. We also conditionally-induced an Lrp5 mutation in cells that contribute to the appendicular skeleton, and not to the axial skeleton, and we observed bone properties were altered in the limbs, and not in the spine. These data indicate that Lrp5 signaling functions locally and suggest increasing LRP5 signaling in mature bone cells as a strategy to treat human low bone mass disorders, such as osteoporosis.
