Research Abstract

dominant negative (DNE)作用を有するp53変異が体癌の高悪性化を誘導する機序を明らかにするために本研究を行い、以下の結果を得た。野生型p53を有する子宮体癌細胞HHUAに導入したp53DNE変異(R273H)は野生型p53の標的遺伝子であるp21、Bax並びにMDM2のpromoterの転写機能を強く抑制した。更に、HHUA細胞の浸潤能および運動能が促進され、浸潤抑制作用のあるMaspin, PAI-1およびKAI1のmRNA発現が低下した。
一方、p53 DNE変異(R273H)の発現はp53 null癌細胞の浸潤能および運動能には関与しなかった。すなわちR273Hは、gain-of-function作用ではなく、野生型p53遺伝子の転写機能を阻害し、癌浸潤抑制遺伝子の発現を抑制することで浸潤能および運動能を促進すると考えられた。DNE作用の無いR213Qには浸潤能、運動能促進作用は認められなかった。
