| Research Abstract |
Aim of this study is to understand the chromosomal regulation for HIV expression. We planned to understand the spatial and chromosomal regulation of HIV provirus by using LacO/I system. To apply LacO/I system, Lac O repeat sequence must be inserted into HIV provirus in vivo. Therefore, we explored the potential of CRISPR/Cas9 system to edit HIV-1 genome as the first step. We found that CRISPR/Cas9 system efficiently cleaved and mutated HIV provirus in T cells, resulting in disturbing the expression. Furthermore, we established a new method that induces precise mutation in HIV provirus through HDR repair pathway using CRISPR/Cas9 system. It is suggested that these technologies enable to insert LacO repeat sequence into HIV provirus and have a potential to discover chromosomal regulation of HIV gene expression.
