Research Abstract |
To clarify regulatory mechanism on epigenetics in bone and joint diseases, we identified Aire as a novel regulator in chondrocyte differentiation using gene expression microarray. Aire possesses PHD domain, which recognizes hypomethylated lysine residues of histone proteins. As the results of analyses of molecular function, Aire can facilitate chondrocyte differentiation through regulating status of histone H3K4me2 in promoter region of Bmp-2 (Si et al BBRC 2013). In terms of osteoclasts, which resorb bone matrix, we tried to figure out dynamic chromatin remodeling during osteoclastogenesis using DNase-seq. Based on the combined information from gene expression and DNase-seq, we successfully identified novel transcription factors in osteoclastogenesis (Inoue et al. JBMR 2014 in press).
