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 tight functional relationship between VDR and Runx2 factors. Additionally, the transcriptional co-activator p300 is recruited to the OC promoter by Runx2 where it up-regulates both basal and 1alpha,25-dihydroxy Vitamin D3-enhanced OC expression. Here, we present an overview of how in osteoblastic cells expressing OC, Runx2 modulates the 1alpha,25-dihydroxy Vitamin D3-dependent stimulation of the OC promoter by first recruiting transcriptional co-activators and then by further stabilizing the interaction of the VDR with the VDRE.
