| Outline of Final Research Achievements |
For the purpose of establishment of cells with efficient expression of recombinant proteins, intranuclear genome dynamics and the genome editing method were investigated. The following results were obtained: The intranuclear arrangement of genes during adipocyte differentiation was not changed even if they expressed. Overexpression of hemimethylated DNA binding protein UHRF1 induced the abnormal shape of the nucleus. Folate deficiency causes the DNA hypomethylation and induces the DNA damage. The specific large genomic region can be deleted by a CRISPR/Cas9 system. Various basic data on intranuclear DNA replication dynamics of Zebrafish cultured cells have been collected.
