Introduction

Canonical Wnt inhibitor Sclerostin (SOST) may be a key mechanotransduction regulator.

Methods

Unloading/loading 10 week old Sost−/− and WT mice. Unloading: Quads and calf muscles injected each with 0.5U botulinum toxin (BTX, Allergan) caused tibial unloading. Loading: 1200 cycles of tibial axial loading, 1200μe on mid-shaft, 4Hz, 5 days/week. Treated and control tibiae μCT scanned (Skyscan 1174) at 2 weeks.
