Research Overview

In order to achieve a comprehensive understanding of the regulatory mechanisms underlying gene expressions, it is necessary to investigate multiple regulatory hierarchies including higher-order genomic structures, epigenetic regulation, transcriptional regulation, post-transcriptional regulation and translational regulation (Fig1). Comprehensive understanding further involves elucidating the intracellular DNA-RNA networks in gene expressions by unveiling relationships between the regulatory hierarchies through the integrative analysis of multiple omics data sets. For this purpose, by taking advantage of molecular biology, biochemistry, cell biology, genetics, genome-wide analyses and bioinformatics techniques, this research group aims to develop an advanced system to investigate a series of regulatory mechanisms that process genomic information into protein synthesis. Ultimately, this system will be used to understand how different phenotypes emerge among different species despite similarities in DNA, RNA, proteins and other cellular infrastructure. Especially, by focusing on the processes responsible for somatic cell reprogramming, cellular differentiation, and organism aging, we have studied the molecular regulatory mechanisms underlying cell fate conversion processes.
