Abstract
The present study aimed to verify the effects of DFO on PDL cells, with particular emphasis on focusing on osteoblastic differentiation. Its mechanisms related to heme oxygenase-1 (HO-1) pathway were also analyzed. DFO increased the expression of HO-1 and early osteoblastic differentiation markers, such as alkaline phosphatase (ALP) and bone sialoprotein (BSP). DFO upregulated heme oxygenase-1. Treatment with HO-1 siRNA blocked the DFO-stimulated osteoblastic differentiation and HO-1 expression. The NF-kB inhibitor pyrrolidine dithiocarbamate, phosphatidylinositol 3-kinase inhibitor Wortmannin, and p38 MAPK inhibitor U0126 blocked the effects of DFO on HO-1 expression and osteoblastic differentiation in PDL cells. Collectively, these data suggest that DFO promotes osteoblastic differentiation and induces the expression of defense protein HO-1 probably via PI3K, p38 MAPK, and NF-kB signalling pathways in PDL cells.
