Outline of Final Research Achievements |
MAPT gene polymorphism is known in diseases that allow accumulation of tau, but it was difficult to analyze the significance of the polymorphism. By using the CORRECT method applying CRISPR-Cas 9 method, we introduce disease-related MAPT polymorphisms and investigate the expression level of tau gene and its effect on splicing. The introduction rate of genome editing improves 1.0% by standard method up to 4.5%. However, the efficiency was still low, and it was revealed that there is a possibility that it may be markedly different depending on genes. When splicing of MAPT was examined using the edited cells, it was confirmed that the ratio of 4R/3Rtau was increased. This cell line can be applied to drug screening to improve the ratio.
