Research Abstract

早期胃がんの内視鏡治療時のCD44v9陽性群では有意に異時性胃がん発生が高率であった。CD44陰性胃癌中分化腺癌細胞MKN28にCD44 variant 9 (CD44v9)、コントロールとしてCD44sを強制発現させたCD44v9-MKN28、CD44s-MKN28を作製した。GSH増強薬NAC投与で、MKN28の5-FU感受性は有意に抑制され、5-FU耐性にGSHが関与すると考えられた。また、CD44v9-MKN28は、MKN28、CD44s-MKN28と比べ有意に5-FU耐性を示した。5-FU投与下でMKN28、CD44s-MKN28では濃度依存性にROS誘導・GSH減少が起こったがCD44v9-MKN28では抑制された。xCT阻害物質sulfasalazine投与でCD44v9-MKN28でも5-FUによるROS誘導・GSH減少を認めCD44v9-xCT系による抗酸化能が5-FU耐性に寄与すると考えられた。NOGマウスに各細胞を皮下注し腫瘍形成後に溶媒、5-FU、5-FU＋sulfasalazine腹腔内投与の3群に分けた。CD44s-MKN28腫瘍は5-FU投与で縮小したがCD44v9-MKN28では縮小しなかった。5-FU+sulfasalazineではCD44v9-MKN28腫瘍は有意に縮小した。さらに上記細胞をCagA陽性ピロリ菌に曝露したHp-CD44-MKN28細胞を作製した。Hpの有無で細胞周期は両細胞間で有意差は認めなかったが、CD44v9-MKN28ではHp群で有意に遊走能が上昇した。CD44s-MKN28、CD44v9-MKN28共に、Hpで有意な浸潤能亢進を認め、CD44v9-MKN28でより浸潤度が高かった。これらの細胞をNOGマウス背部皮下に移植したところ、CD44v9-MKN28群の移植後腫瘍体積はHp群で有意に高値であった。別系ではCD44v9発現vectorをHER2陽性胃高分化型腺癌細胞NCI-N87に形質転換した（CD44v9-NCI-N87）。NCI-N87ではtrastuzumab用量依存性に細胞生存率は低下しROS蓄積を認めた。CD44v9-NCI-N87ではtrastuzumab投与でも生存率は低下せず、ROS蓄積も認めず、HER2発現細胞でもCD44v9発現でtrastuzumab耐性を獲得することが示された。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

CD44v9陽性胃がん幹細胞の抗がん療法（S-1, trastuzumab)に対する耐性の分子機序を詳細に検討し、CD44v9発現によるシスチントランスポーターであるxCTの安定化によるシスチン取り込み、細胞内グルタチオン(GSH)蓄積とそれによる細胞内ROS抵抗性による、薬剤耐性機序の寄与について、胃がん化学療法の主翼を担う2剤で明らかにすることができた。S-1,つまりその代謝物である5-FUの耐性機序は本トランスポーター増強の寄与度は高いものの、trastuzumabの場合は、必ずしも本系だけではないという結果が得られてきており、薬剤によりその耐性を担う細胞形質が若干異なると考えられた。つまり、trastuzumabの場合は、細胞内GSH濃度の増強だけでなく、ミトコンドリアに存在する抗酸化酵素MnSOD量もCD44v9-NCI-N87で、NCI-N87に比し上昇しており、HER2陽性細胞のtrastuzumab耐性機序にはxCTに依存度の高いGSH増強によるROS抵抗性ばかりでなく、MnSOD誘導によるROS抵抗性も獲得することで薬剤耐性を発揮している可能性が考えられた。このため、本機序の詳細をin vitroでさらに明らかにした上で、in vivoあるいはPET/CT診断検査への応用が必要であると考えられ、この段階の基礎的検討を行う必要が生じた。

Strategy for Future Research Activity

HER2陽性肝転移胃高分化型腺癌細胞株NCI-N87ではtrastuzumab用量依存的に細胞生存率は低下し、細胞内ROS蓄積を認めたものの、CD44v9-NCI-N87ではtrastuzumab投与でも生存率は低下せず、ROS蓄積亢進も認めなかったことから、HER2発現細胞でも、CD44v9発現によりtrastuzumab耐性を獲得することが示されたが、この機序はxCT依存性のGSH蓄積性ばかりでなく、ミトコンドリア内でのMnSOD誘導も重要であることがわかったため、まずは、この機序を詳細に検討する。これらの知見の確認ができた上で、in vitro での細胞標識実験を実施し、さらにNOGマウスを用いた担がん動物でのがん腫の悪性化、さらには標識細胞の検出技術に応用し、CD44v9陽性胃がん幹細胞のアミノ酸代謝を標的した新規診断法開発の基盤構築を実施する予定である。
