11 May 2007
Abstract excerpt
Runx2 is an essential transcription factor for osteoblast differentiation. However, the functions of Runx2 in postnatal bone development remain to be clarified. Introduction of dominant-negative (dn)-Runx2 did not inhibit Col1a1 and osteocalcin expression in mature osteoblastic cells. In transgenic mice that expressed dn-Runx2 in osteoblasts, the trabecular bone had increased mineralization, increased volume, and...
