| Outline of Final Research Achievements |
Cytosine methylation in genome contributes to gene silencing through changing chromatin state. At present, hydroxymethylcytosine (5hmC) produced from methylcytosine (5mC) by TET oxigenase is thought to be an possible intermediate for demethylation. Hence, a technique to analyze 5hmC at single base resolution in genome contributes to understanding of demethyltion processes. However, the reported techniques to analyze 5hmC harbor some disadvantages. In this period, I have successfully established two independent method to analyze 5hmC at single resolution, as I planned. One is enzymatical method and the other is chemical one. From my research, highly reproducible results are able to be obtained by these two easy methods. Thus, this project could contribute to the advance of functional understanding of 5hmC.
