Research Abstract	難治癌とされる肺癌の転移・血管新生因子を分子標的とした制御法の開発を目的に検討を行い、以下の成果を得た。1)臨床上問題となる脳転移と骨転移について、マウスを用い、臨床に近いヒト肺癌細胞の脳転移および骨転移モデルを確立した。2)がん性胸水形成には胸膜浸潤とVEGF高発現の2つのステップが必要であることを明らかにし、さらにVEGF受容体阻害剤の投与で、癌性胸水形成が有意に抑制され、分子標的治療の一つとして臨床応用できる可能性を示した。3)肺腺癌の脳転移モデルを用い、VEGFが拡張血管形成を誘導し脳転移を促進していることを明らかにした。4)腫瘍との相互反応に関与する宿主側細胞としてNK細胞に着目し、NK細胞intactのSCIDマウスを用いてMCP-1遺伝子導入肺癌細胞の転移形成能を検討し、MCP-1により活性化されたNK細胞が転移形成の抑制に重要な役割を果たすことを明らかにした。5)肺癌細胞に比較的選択的に発現しているgangliosideGM2を腫瘍抗原としてとらえ、in vitroにおいてヒト化抗GM2抗体が肺癌患者の単核球の抗体依存性細胞障害反応を介し小細胞肺癌を障害すること、ヒト肺癌転移モデルにおいて抗癌剤耐性小細胞肺癌の遠隔転移を抑制することを明らかにし、抗GM2の臨床応用の可能性を示唆した。6)シアロ糖脂質分子群生合成系のキーエンザイムで、ヒト白血病細胞の分化誘導能を持つgangliosideGM3を合成する糖転移酵素(Sialyltransferase-1/ST3GalV)のゲノム構造を明らかにした。この酵素遺伝子をヒト大腸癌HCT116細胞に導入して、GM3を過剰に発現させると癌細胞のアポトーシスが誘導された。今後、転移・血管新生機構についてさらに詳細な分子生物学的解析を進めるとともに、新規分子標的治療の開発に向けた検討を行う予定である。
