Outline of Research at the Start

バイオ人工臓器(異種移植)の分野では、当初、相同組み替え法は困難を極めたが、新法によるknockout(KO)法が我々も含めブタでも成功している。しかし、CRISPR/Cas9法には特許の問題が絡んでおり、今回研究協力者の真下知士グループが開発したCRISPR/Cas3法を応用してKO-ブタの作出を進める。現時点でブタ細胞での有効性はまだ確立されていない。ブタの繊維芽細胞、等を使って、先ずはこのCas3法で既にCas9法でKO経験のあるブタGalTと4GalNT2のKOを比較しながら行う。次に、SLA ClassI,II、とPERV(内在性レトロウイルス)-CのKOの有効性の検証を行う。

Outline of Final Research Achievements

In order to apply the CISPR/Cas3 method to pig cells, we attempted knockout (KO) of GGTA1 and porcine endogenous retrovirus (PERV)-C.
Focusing on exon 9 of GGTA1, we prepared target plasmids and introduced them into pig fibroblast cells. First, the expression of Gal-epitope was analyzed by FACS, and then nested PCR was performed. Furthermore, the PCR products of each group were transformed into E. coli, and a large number of colonies were checked by PCR, Sanger method . The results demonstrated a deletion of 294-754bp was produced in GGTA1 gene.
Next, we focused on PERV-C and attempted to KO it using just the same as the Cas3 method for GGTA1. However, it was not possible to analyze the deletion of PERV-C in E.coli colonies, because of sit number of PERV. However, in conclusion, we confirmed the effectiveness and feature of the CRISPR/Cas3 method in xenotransplantation.

Academic Significance and Societal Importance of the Research Achievements

この研究で、異種移植分野の(ブタを使った)臓器開発での遺伝子のtargeting法で、一般に普及しているCRISPR/Cas9を使わずに、日本で開発されている新たな方法であるCRISPR/Cas3を使うことが可能になれば、特許の問題を気にせずに遺伝子編集が可能になる。これは単に異種移植分野だけでなく、他の医学・畜産、等の分野に大きく影響をもたらす。
