| Outline of Final Research Achievements |
Cas9, gRNA expression vectors, and homologous recombination vector were transfected into breast cancer cell line MCF-7 using genome editing. fluorescent genes Venus was inserted into the C-terminal side of the SOX2 gene. In the cell line of the homologous recombinant, although it localized in the nucleus and emitted green fluorescence, the fluorescence was weak, and it was difficult to analyze the localization of intracellular cells as live cells by fluorescence microscopy. In addition, there was variation in cell proliferation for each cell line compared to the parent strain, and off - target by gRNA was predicted. Similar results were found in genomic editing of other genes. Therefore, Cas9 protein and gRNA complex were formed in vitro and introduced. Currently, we analyze new homologous recombinants.
