Research Abstract

胃癌で発現が低下するmicroRNA-375は、胃癌細胞株MKN74に導入することで、標的であるPDK1の翻訳を抑制し、PI3K-Akt系を抑制し、細胞増殖を抑制することが報告されており、発癌抑制に関与すると考えられる。microRNA-375導入胃癌細胞では、シスプラチン(CDDP)のIC50が減少し、アポトーシスが促進され、CDDPの抗癌作用が増強することが示された。さらに、microRNA-375導入細胞では5-fluorouracil (5-FU)感受性も有意に増強された。一方、胃癌の癌幹細胞の表面マーカー、CD44 variant 9 (CD44v9)発現により、細胞内へのシスチンの取り込みと還元型glutathione量が増加し、ROS抵抗性が獲得される。CD44v9発現細胞では、CDDP、5-FU耐性を獲得するが、この時、CDDP、5-FU投与後のmicroRNA-375の誘導率は低下した。別系で、食道扁平上皮細胞HET-1AにCDX2発現ベクターを導入した細胞(HET1A+Cdx2)とmockベクターを導入した細胞(HET1A+LacZ)を作製した。コール酸でHET1A+LacZで細胞増殖は抑制されたが、HET1A+Cdx2では促進され、HET1A+Cdx2中で、CDX2量は減少、microRNA-221/222発現は上昇、p27Kip1発現は低下した。胆汁酸は、microRNA-221/221の発現を上昇させ、p27Kip1を減少させ、CDX2分解を促進した。ヒト食道腺がん組織でも、バレット食道に比し食道腺がんでmicroRNA-221/222発現が増加した。食道腺がん細胞OE33をNOGマウスの背部に移植し、腫瘍塊形成後、アパタイトナノキャリアを用いてanti-microRNA-221/221を作用させると、CDX2量は上昇し細胞増殖が抑制された。
