Abstract excerpt
The steroid hormone 1,25-(OH)2-vitamin D3 (VD3) regulates osteoblast differentiation by either activating or repressing transcription of numerous bone phenotypic genes. We addressed whether VD3 also influences osteogenesis by controlling activity of the runt-related transcription factor Runx2/Cbfa1, a key regulator of bone formation in vivo. Our data showed that expression of Runx2 was downregulated by VD3 within...
