Research Abstract	肝癌に対する遺伝子治療の確立を目標とし、肝癌発生あるいは肝癌発育に重要な役割を演じている分子を同定するために、種々の基礎的検討を行い、以下のごとき成果を得た。まず、ヒトにおける種々の肝疾患組織を用いて、肝癌発生における細胞周期関連分子の関与を検討したところ、慢性肝炎および肝癌周囲の肝硬変組織に比較し、肝癌ではサイクリンD1、サイクリンE、サイクリンAおよびサイクリン依存性キナーゼ(Cdk)4さらにWee1が、量的に増加しているのみならず、酵素活性が上昇していることを報告した(Hepatology, in press)。さらに,ヒト肝癌においては、p33^<ING1>やp57^<KIP2>などのCdk inhibitorの発現量ならびに活性が低下していることも確認した(Int J Oncol 20:769-775, 2002; Scand J Gastroenterol 37:1440-1448,2002)。また、我々はすでに、肝癌発育には血管内皮増殖因子(VEGF)の発現が必須の因子であることを報告しているが(Hepatology 28:1489-1496,1998; Hepatology 30:1179-1186,1999; CancerRes59:4413-4418,1999; Hepatology 33:841-847,2001)、本年度の検討において、basic fibroblast growth factor(bFGF)の発現が、VEGFの発現によって誘導される肝癌発育を相乗的に促進することを報告した(Hepatology 35:834-842,2002)。以上の結果より、肝癌発生および肝癌発育に重要な役割を担っているサイクリン、Cdkなどの細胞周期関連分子、あるいはVEGFやbFGFなどの腫瘍発育促進分子の発現を制御できれば、肝癌の発育のみならず発生を抑制し得る可能性が示された。事実、遺伝子レベルにおける制御ではなく、蛋白質レベルにおける検討ではあるが、肝発癌モデルラットにアンギオテンシン変換酵素の阻害剤を投与すれば、アンギオテンシンIIの活性を抑制することによってVEGF活性が抑制され、肝線維化の抑制のみならず肝癌発生を阻止し得ることを確認している(Clin Cancer Res 7:1073-1078,2001; J Hepatol 37:22-30,2002)。本年度の研究成果より、肝癌の発生ならびに発育を制御し得る可能性のある分子が判明してきており、今後はこれらの分子の発現を遺伝子レベルで制御することによって、肝癌の発生および発育を阻止し得る遺伝子治療の可能性を検討していく予定である。
