Outline of Final Research Achievements

Drug delivery system (DDS) is key factor for successful realization of nucleic acid (NA) medicine, especially when siRNA and microRNA are employed. We have demonstrated that the super apatite delivery system provided successful treatment using siRNA and microRNA in various mice models, including cancer, inflammatory bowel disease and infectious disease. In this project, we go on developing a novel DDS, iNaD (inorganic nanoparticle device) which enables improved tumor accumulation of NA and avoidance of adverse events in normal organs. At the same time we tried to develop novel nucleic acid medicine for refractory diseases. Mir-4711 was a major product which targets KLF5, MDM2 and DP1 and exhibited inhibition of cancer stem ness in colon and pancreatic cancer cells. Development of other products are also underway against hepatocellular carcinoma, lung cancer, breast cancer, esophageal cancer, ovarian cancer, biliary tract cancer and so on.

Academic Significance and Societal Importance of the Research Achievements

ヒト用のDDSであるiNaDによって、既存のスーパーアパタイトに比べてマウス腫瘍への集積は大幅に向上した。一方、iNaDでは現存のDDS共通の問題である肝臓へのデリバリーはほとんどなく、副作用の低減に寄与する。iNaDの大量生産を行いラットを用いた実験では標準投与量の50倍以上を安全に投与できたので、今後サルへの投与を行う。新しい核酸医薬であるmiR-4711は大腸癌、膵癌の癌幹細胞に対する特効薬として期待される。本研究の結果は、難治性疾患に対する治療法創造の道筋をつけるものであり、学術的、社会的意義は大きい。
