Outline of Final Research Achievements

In the present study, we constructed anti-microRNA oligonucleotides(CL-AMOs)and transfected them into cells. From northern blotting analyses, 3’-end trimming and tailing of miRNA were mediated in transfection of the AMO containing the CL-duplex at 3’-end. After transfection, most of single-stranded AMO molecules were promptly transported to nucleus, while CL-AMOs remained in cytoplasm. In addition, we transfected CL-AMO into breast cancer cell line, verified that CL-AMO could suppress breast cancer cell proliferation for a long duration, compared to single stranded or commercially available AMOs.

Academic Significance and Societal Importance of the Research Achievements

これまで、CL2本鎖を導入することでAMOの活性が大きく向上することは明らかにしていたが、miRNAにどのような影響を与えているか、また2本鎖構造が核酸の細胞内における分布にどのような影響を与えるかは明らかでは無かった。今回、CL2本鎖を有するCL-AMOが結合したmiRNA側が、AMOの構造に依存して特異な修飾を受けることを明らかにした。加えて、細胞に導入されたAMOの細胞質から核内への移行が分子構造に依存する可能性も見出した。さらに、CL‐AMOが市販のAMOよりも長期間に渡って乳がん細胞の増殖を抑制したことから、乳がん治療における新たな治療につながる技術を本研究より得ることができた。
