Abstract: BFP-mRNAに対して脱アミノ化誘起用ODNを用いて光化学的な部位特異的脱アミノ化処理を行った。光化学的RNA editingは、RT-PCR-RFLPとin vitro翻訳したタンパク質の蛍光を確認した。また、光化学的RNA editingした当該mRNAの全長をシークエンスし、他の箇所に変異が生じていないことも確認した。効率的な脱アミノ化を誘起するODNデザインについても検討し、相補的配列長が14塩基で、ヘアピン長が9塩基のODNが12.4%と最も高い光化学的RNA editing効率を示した。この結果は光化学的RNA editing法が疾患治療法として適用可能であることを示唆している。:Photochemical site-specific deamination was performed toward BFP-mRNA, by using oligodeoxynucleotides,ODNs, for inducing deamination. The base substitution by artificial RNA editing was confirmed by RT-PCR-RFLP analysis and fluorescence of in-vitro-translated proteins. Moreover, the mRNA sample was sequenced after photochemical RNA editing treatments, and confirmed that there was no mutation occurred except the target-site. We also investigated the ODN design that could induce efficient deamination. The ODN with complementary sequence length of 14 bases and hairpin length of 9 bases showed the highest photochemical RNA editing efficiency at 12.4%. This result suggests that the photochemical RNA editing is applicable as a theraputic method for genetic diseases.
