| Outline of Final Research Achievements |
In this study, we used high pressure and investigated to regulate gene expression by changing the stability of non-canonical structure of nucleic acids selectively. As a result, the non-canonical structures such as G-quadruplex was largely destabilized with increasing pressure. By using this property, we found that gene expression from the DNA including non-canonical nucleic acids structure could be regulated by tuning pressure. These results shed light on the development of novel system of gene expression by using pressure changes and the elucidation of the origin of life, which was possibly born under a high pressure condition.
