dc.description.abstract | Background It has been well established that daily injections of low dose parathyroid hormone (PTH) increase bone mass in animals and humans. However, the precise mechanisms by which PTH exerts its anabolic action on bone are incompletely understood. The canonical Wnt-β-catenin signaling pathway has recently been demonstrated to have an important role in bone cell function. In the present study, we have examined the interaction between the PTH and Wnt signaling pathways in mouse osteoblastic MC3T3-E1 cells. Methods & Results MC3T3-E1 cells were treated with 0.01?0.84 µM recombinant PTH. β-catenin expression was significantly increased after 30 minutes of exposure to PTH and reached a maximum 2.7 fold increase at 1 hr and expression then faded at 6 hrs. In addition, treatment with PTH increased nuclear accumulation of activated β-catenin; the ratio between the nuclear to cytoplasmic protein was more than three fold at 30 minutes and beyond. Moreover, PTH stimulated T-cell factor/lymphoid enhancer factor (TCF/LEF) reporter gene activity in MC3T3-E1 cells. Confocal microscopy revealed nuclear translocation of β-catenin by PTH as compared with a glycogen synthase kinase-3β (GSK-3β) inhibitor. Conclusion These results suggest that the anabolic mechanism of PTH might be partially associated with the Wnt-canonical pathway. The appropriate target of another anabolic agent should be determined through further studies of this pathway. | - |
