| abstractText | Phosphorylated p38 mitogen-activating kinase (MAPK) is observed in osteoclasts under in vivo inflammatory situations. However, the role of p38 MAPK in osteoclast function has not been elucidated, because all external stimuli tested hitherto failed to induce the phosphorylation of p38 MAPK in osteoclasts in culture. In this study, a constitutively active form of MKK6 (MKK6CA) was expressed in osteoclasts using adenoviral gene transfer in vitro. MKK6CA expressed in osteoclasts phosphorylated p38 MAPK and enhanced the survival of osteoclasts. Dentine-resorbing activity of osteoclasts was not enhanced by the MKK6CA expression. These results suggest that p38 MAPK signaling plays a critical role in the survival of osteoclasts in inflammatory diseases. |
