Outline of Annual Research Achievements |
がん遺伝子の網羅的機能解析として、68遺伝子、243バリアントについて、マウス線維芽細胞株にがん遺伝子を導入し、focus formation assay及びMANO法によるがん化能評価を行った。 さらに、様々ながん細胞株にがん遺伝子を導入し、表現型の変化をfocus formation assayおよびsoft agar colony formation assayで評価した。 MANO法を用いた分子標的薬耐性化メカニズムの解明として、様々ながん細胞株にがん遺伝子243バリアントを導入して、各分子標的薬に対する薬剤感受性をMANO法を用いて評価したところ、分子標的薬に対する耐性マーカーが複数同定された。また、取得された薬剤耐性バリアントを個別に細胞株に導入し、耐性化を検証した。さらに薬剤投与下でmRNAの発現解析、タンパク質リン酸化の解析を行い、耐性化のメカニズムを評価した。併用療法による耐性化解除の検討として、複数のバリアントの組み合わせを遺伝子導入した細胞株を用意し、薬剤併用試験のアッセイ系を確立した。さらに、MAP2K1の複数のがん遺伝子の組み合わせによりがん化した発がんモデルを用いて、薬剤併用試験による最適化薬剤の組み合わせおよび最適濃度の評価し、論文発表を行った (Mizuno S, et al. Mol Cancer Ther., 2023)。リキッドバイオプシーを用いた薬剤耐性化メカニズムの解明として、末梢血及び病変部組織 (生検・手術検体または過去に保存された FFPE ブロック等)より, DNA/RNA を抽出し, 血漿中に存在する cfDNA/RNAを精製し, ターゲットシークエンス, トランスクリプトーム解析を行い, 耐性・奏効性と関連するバイオマーカーの同定を行った (Koyama T, et al. Cancer Discov., 2023)。
