| Research Abstract |
Aim of this study is to analyze the epigenetic feature of the gene expression abnormalities in somatic cell cloning by nuclear transfer and the establishment of the methods to identified the genome-wide epigenetic transcriptional regulation domains through the analysis of gene expression profiles of the somatic cell cloned mice.
In this study, I propose a novel method to identify the gene expression domains with same expression pattern by calculating the Pearson's distance between the neighbouring genes on the chromosome. This method is easy way to identify gene cluster that is coregulated in the samples examined by DNA microarray with high throughput.
For the understanding of the basic nature of somatic cell done abnormalities, we examined the detailed histology of the clone placenta at the time point just after the implantation when most of the done embryos stop their development. It is also demonstrated that the gene expression change including genomic imprinted genes was induced in the done mice, not only in the neonatal tissue of doned mice, but also in the embryonic stem cells derived from cloned mouse embryos.
