| Outline of Final Research Achievements |
Recently, the relationship between mental disorder and abnormal DNA methylation in neuron has been reported. However, this detail mechanism remains unknown. To address this issue, we generated novel epigenome editing system using zinc finger protein (ZF) and DNA methyltransferase (DNMT). This system, named ZF-DNMT, induced DNA methylation on target genome region and reduced the expression level of target gene in human neural stem cells. Furthermore, we focused on histone demethylase LSD1, which is used for epigenome editing and interacts DNMT, and found that LSD1 is necessary for human neurogenesis.
