Research Abstract	近年の発がん遺伝子やがん抑制遺伝子に関する研究の進展は、がん発症の仕組みを分子レベルで理解する上で大きく貢献した。さらにまた、発生工学的手法を用いたがんモデル動物に関する研究や、ゲノムプロジェクトに基づくがん関連遺伝子の研究の進展は、細胞の増殖制御に関する、遺伝子・蛋白質・細胞レベルの研究と相俟って、がん研究を進展される大きな力となっている。一方でこのような遺伝子レベル研究成果に基づいて、特定のがんの遺伝子診断が可能となっている。またがん遺伝子・がん抑制遺伝子とその産物の機能に関する知見に基づいて、遺伝子治療をはじめとする新しいがん治療の試みが大きく進展しようとしている。このような研究において、我が国の研究者が果たしている役割は極めて大きい。一方で、アメリカ合衆国等アメリカ大陸のいては、国際的にも極めて先進的な研究が進められている。我が国のがん研究に従事している第一線の研究者がそのような研究者と交流を深め、共同研究や情報交換を推し進めることは、我が国のがん研究、がん治療を推進する上で大変有意義である。その目的に沿って本年度は22名の研究者を米国の研究室や研究集会に派遣した。我が国のがん研究の進展を支えている文部省科学研究費「がん重点」の総括班から推薦された研究者を中心に、今年度は特にがん転移、がん遺伝子診断に重きをおきながらも、がん研究の諸領域、つまりがん治療、抗がん剤、免疫、ゲノム安定性、疫学、シグナル伝達、細胞周期、不死化、ウイルス発がんに係わる研究を推進している研究者を派遣した。このような派遣を通して、細胞増殖の制御、がん転移に関する新しい視点を得、たがん治療に関して薬品設計や遺伝子治療等の貴重な情報の交換を行った。
