Outline of Final Research Achievements

A heterozygous nonsense mutation in the FAM83H gene has been demonstrated to cause autosomal-dominant hypocalcified amelogenesis imperfecta (ADHCAI) in humans. In the present study, we generated genetically modified mice with a mutation in the FAM83H gene, and tested whether the FAM83H mutation causes ADHCAI in mice; however, the FAM83H-mutant mice did not show any signs of defects in enamel. Our results suggest that a mutation in the FAM83H gene is not sufficient to cause ADHCAI in mice. On the other hand, mice with the homozygous mutation in the FAM83H gene showed the phenotypes of retardation in the postnatal growth and a scruffy coat. The disorganization of the keratin cytoskeleton, the disordered cell alignment, and the impaired intercellular adhesion were observed in various epithelial tissues of homozygous mutant mice. Our data suggest that FAM83H plays an important role in the establishment of epithelial tissues through properly organizing the keratin cytoskeleton.

Academic Significance and Societal Importance of the Research Achievements

本研究によって、マウスがADHCIAのモデル動物作製には適していないことを明らかにした。本結果は、マウス以外の動物種を使ってADHCAIのモデル動物作製を促すことに繋がる。FAM83Hが上皮組織でケラチン骨格構造制御に関与していることを見出した点は重要である。ケラチン骨格により裏打ちされるヘミデスモソームの構成タンパク質の変異が、エナメル質形成不全症の原因になることが知られており、歯牙組織のケラチン骨格構造異常がADHCAIに繋がる可能性が考えられる。FAM83Hが、マウスよりもヒトで、ケラチン骨格構造制御により強く関わっている可能性の検証を促す成果であると考えている。
