Research Abstract

MC3T3E1 cells treated with differentiation medium could not express osteocyte marker genes. Therefore, we focused on epigenetic regulation during osteocyte differentiation. ChIP analyses revealed that methylation levels of H3K4 and K27 on transcriptional start sites of osteocyte marker genes were bivalent status, suggesting that demethylation of H3K27 might to be essential for the differentiation from osteoblast to osteocyte. To examine physiological impact of this phenomenon, we generated flox mice of Kdm6A, demethylace for H3K27.
