Abstract excerpt
Mutations in the Wnt co-receptor LRP5 alter bone mass in humans, but the mechanisms responsible for Wnts actions in bone are unclear. To investigate the role of the classical Wnt signaling pathway in osteogenesis, we generated mice lacking the beta-catenin or adenomatous polyposis coli (Apc) genes in osteoblasts. Loss of beta-catenin produced severe osteopenia with striking increases in osteoclasts, whereas...
