Research Abstract

ヒト頭頸部扁平上皮組織を用いて、シクロシキゲナーゼ(COX)系の代謝およびその受容体について検討した。COX-2は正常組織と比較して癌組織に強い発現が認められ、特に癌細胞そのものに強い発現を認めた。COXの下流酵素であるプロスタグランジンE合成酵素(mPGES)も癌細胞、特にその核周囲に強い発現を認め、COX-2とPGESの連関が示唆された。COX-2、mPGESともに高分化癌で強い発現がみられた。RT-PCRによる検討でも、COX-2、mPGESともに高分化癌の方が高い値を示した。リンパ節転移の有無で、COX-2ではN0で高い値を示した。PGE2の受容体は4種類の受容体すべてにおいて癌細胞に発現がみられた。
