Abstract excerpt
UNLABELLED: Wnt/beta-catenin signaling has recently been suggested to be involved in bone biology. The precise role of this cascade in osteoblast differentiation was examined. We show that a Wnt autocrine loop mediates the induction of alkaline phosphatase and mineralization by BMP-2 in pre-osteoblastic cells. INTRODUCTION: Loss of function of LRP5 leads to osteoporosis (OPPG syndrome), and a specific point...
