Outline of Annual Research Achievements |
①世界初で食道扁平上皮癌の生検組織から3D培養しオルガノイドの作成に成功し,形成オルガノイドは,作成率,大きさ,形態,継代に各症例で違いを認めていること,さらに 5FUを用いて抗癌剤耐性を確認したところ,癌オルガノイドは化療耐性を示しており,実際の臨床奏効とも相関を認めていることを明らかにし,論文発表した(Kijima T et al, Three-Dimensional Organoids Reveal Therapy Resistance of Esophageal and Oropharyngeal Squamous Cell Carcinoma Cells. Cell Mol Gastroenterol Hepatol. 2018 Sep 14;7(1):73-91).現在,オルガノイドとfibroblastとの共培養またCancer Associated Fibroblast(CAF)も検討に加え,培養環境の条件を検討中である. ②臨床サンプルの次世代シークエンス解析によって抽出されたマイクロRNA, miR-148a-5p (Fukuhisa H et al, Gene regulation by antitumor miR-130b-5p in pancreatic ductal adenocarcinoma: the clinical significance of oncogenic EPS8. J Hum Genet. 2019), miR-130b-5p(Kawagoe K et al, Regulation of aberrantly expressed SERPINH1 by antitumor miR-148a-5p inhibits cancer cell aggressiveness in gastric cancer. J Hum Genet. 2020), miR-204-5p(Khalid M et al, Gene Regulation by Antitumor miR-204-5p in Pancreatic Ductal Adenocarcinoma: The Clinical Significance of Direct RACGAP1 Regulation. Cancers (Basel). 2019)が,胃癌,膵臓癌において,それぞれ,SERPINH1,EPS8,RACGAP1を抑制し,がん抑制に働くことを報告した. さらに,これらのマイクロRNAのオルガノイドでの発現を検討している.

Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
さらに,EMT関連分子とNotch familyにも着目し検討を進めるている.治療耐性について大腸癌の化学療法後切除サンプルで次世代シークエンス解析を行っており,多方面からのアプローチを行っている.特に癌細胞の分化度に関する分子を同定し検証を行っている.
|
Strategy for Future Research Activity |
培養細胞を用いたオルガノイドとCAFを含めたfibroblastとの共培養を進めていく一方で,EMT関連分子,Notch familyのオルガノイドでの発現を検討,さらには,網羅的解析,分化誘導実験,加療後に切除を行った組織のオルガノイド培養を進めていく.

Causes of Carryover |
新型コロナウイルスの影響で、予定していた打ち合わせを延期せざるを得なかった。打ち合わせ可能となり次第、打ち合わせ費用として2020年度に使用する予定である。
