| Research Abstract |
We successfully mapped locus for each of chromosome 6, 15, and 17, for home-cage activity, social behavior, and anxiety-like behavior, respectively. In each of the locus, we found a strong candidate gene, and analyzed gene expression level. In the case of the candidate gene for anxiety-like behavior on chromosome 17, we found that repeat sequence associate with regulation of the expression by conducting luciferase assay using cultured cells. Furthermore, we confirmed that the difference of gene expression of the candidate gene resulted in different level of the protein product in the mice, thus possibly associate with the difference in anxiety-like behavior.
