| Outline of Final Research Achievements |
The aim of this study is to elucidate the mechanism of pattern formation regulated by histone deacetylase (Hdac) during rat embryonic mandibular development. Knockdown of Hdac1 in rat mandibular organ culture up-regulated the gene expression of endothelin receptor type A (Ednra) and Hoxa2. It is well known that Ednra is expressed by the neural crest-derived ectomesenchymal cells of mandibular arch, and plays an important role during mandibular pattern formation. Hoxa2 is a marker for the second branchial arch. Up-regulation of Hoxa2 gene expression in the first arch indicates that Hdac1 knockdown leads to a transformation of second arch. These data suggests that Hdac1 plays an important role during rat embryonic mandibular development by regulating key gene expression.
