Bone-specific transcription of the osteocalcin (OC) gene is principally regulated by the Runx2 transcription factor and further stimulated in response to 1alpha,25-dihydroxy Vitamin D3 via its specific receptor (VDR). The rat OC gene promoter contains three recognition sites for Runx2 (sites A-C). Mutation of sites A and B, which flank the 1alpha,25-dihydroxy Vitamin D3-responsive element (VDRE), abolishes 1alpha,25-dihydroxy Vitamin D3-dependent enhancement of OC transcription, indicating a… CONTINUE READING
