| Outline of Final Research Achievements |
We have previously reported that the inflammatory cytokine, tumor necrosis factor α (TNFα) inhibits BMP-induced osteoblast differentiation via NF-κB signaling. In the present study, we examined the effects of a steroid-coactivator, Macromolecular Translocation Inhibitor II (MTI-II), on inflammatory responses（Endocrinology, 2016）. MTI-II was previously demonstrated as an enhancer of the transcriptional activity of glucocorticoid-bound glucocorticoid receptor. We examined the effects of MTI-II on the inhibition of odontoblastogenesis by TNFα. When the cells were treated with TNFα, ALP activity was inhibited, while MTI-II restored TNFα-mediated inhibition of the activity in a dose-dependent manner (J Cell Biochem, 2016). MTI-II potentially acts as an anti-inflammatory drug.
