概要 Tissue-specific gene expression is subjected to epigenetic and genetic regulation. Posttranslational modifications of histone tails alter the accessibility of nuclear proteins to DNA, thus affecting the activity of the regulatory complex of nuclear proteins. Methylation at histone 3 lysine 9 (H3K9) is a crucial modification that affects gene expression and cell differentiation. H3K9 is known to have 0-3 methylation states, and these four methylated states are determined by the expression of sets of histone methyltransferases. During development, teeth are formed through mutual interactions between the mesenchyme and epithelium via a process that is subjected to the epigenetic regulation. In this study, we examined the expression of all H3K9 methyltransferases (H3K9MTases) during mouse tooth development. We found that four H3K9MTases-G9a, Glp, Prdm2, and Suv39h1-were highly expressed in the tooth germ, with expression peaks at around embryonic days 16.5 and 17.5 in mice. Immunohistochemical and in situ hybridization analyses revealed that all four H3K9MTases were enriched in the mesenchyme more than in the epithelium. Substrates of H3K9MTases, H3K9me1, H3K9me2, and H3K9me3 were also
