Outline of Final Research Achievements

Based on the chemical reactions developed by us, the studies on highly efficient detection methods for epigenetic modifications have been carried out. The results are as follows: (i) Highly bright detection of methylation in DNA repeat sequences to understand heterogeneity in tumors, (ii) High performance analysis of the products in demethylation process to make prognostication for tumors efficient, (iii) Chemical reproduction and analysis of histone structures for control of gene expression.
