Outline of Final Research Achievements

Epigenetic mechanisms that are governed by histone acetylation are considered to have a critical role in neuronal differentiation. In this analysis, we have attempted to generate transgenic mice that would be capable of decreasing an expression level of CBP protein, a causative protein for Rubinstein-Taybi syndrome. In addition, we have analyzed effects of in utero exposure of valproate, a putative candidate for treating Rubinstein-Taybi syndrome, on cerebral cortical histogenesis. Valproate exposure in utero increased the thickness of cerebral cortex by affecting the cell cycle kinetics of neuronal progenitor cells.
