| Outline of Final Research Achievements |
To narrow down the possible list of causative genes at loci or chromosomal regions, where genetic associations are detected through exploratory analyses such as genome-wide association study (GWAS) and to further elucidate the biological mechanisms of mRNA expression changes by such causative genes, we have addressed three principal themes in the case of metabolic disorders as follows. First, we have performed fine mapping of loci, which are found to be associated with metabolic disorders phenotypes in the inbred rats, thereby narrowing down the list of causative genes. Second, we have investigated impacts of epigenomic changes, in particular, DNA methylation changes, on the regulation of mRNA expression. Third, we have evaluated clinical significance of microRNA, another key component of epigenomic changes, in the gene-environment interaction and have successfully found its usefulness as a pathological biomarker.
