1 In the present study, we firstly found that SD could induce G1 arrest and the differentiation of human osteoblastic MG-63 cells, as evidenced by the increase of osteoblastic differentiation markers, such as bone morphogenetic protein-2 (BMP-2), osteocalcin and runt-related transcription factor 2 (Runx2). SD 0006 RUNX family transcription factor 2 Homo sapiens

3 Site-directed mutagenesis revealed that the Runx2 binding sites located side-by-side at positions -232 and -222 are essential for the SD-induced expression of hST3Gal V in MG-63 cells. SD 0006 RUNX family transcription factor 2 Homo sapiens
4 These results suggest that SD triggers upregulation of hST3Gal V gene expression through Runx2 activation by BMP signaling in MG-63 cells. SD 0006 RUNX family transcription factor 2 Homo sapiens
