Research Abstract |
We investigated the molecular mechanisms triggered by the alternative NF-kB pathway in the regulation of osteoblast and osteoclast differentiation. Osteoblastic differentiation induced by BMP2, as shown by alkaline phosphatase activity. Smad1 phosphorylation was also enhanced in primary osteoblasts from aly/aly mice. The ectopic bone formation in vivo that was induced by BMP2 was enhanced in aly/aly mice compared with controls. On the other hand, the overexpression of RelB in aly/aly bone marrow cells rescues RANKL-induced osteoclastogenesis by inducing p100 processing. Cot, an MAP3K, was up-regulated by RelB overexpression and knocking down of Cot expression significantly reduced the RANKL-induced osteoclastogenesis induced by RelB overexpression. Thus, the alternative the NF-kB pathway via the processing of p52 from p100 negatively regulates osteoblastic differentiation by modifying BMP activity and positively regulates RANKL-induced osteoclastogenesis.
