Gerhard Krönke and his colleagues show that PPARβ/δ regulates Wnt signaling in osteoblasts, which in turn determines the proper ratio of OPG to RANKL and thus bone homeostasis. They go on to show that pharmacological activation of this receptor normalizes bone density in a mouse model of osteoporosis.
