Research Abstract

潰瘍性大腸炎を代表とする慢性炎症性疾患は長期罹患により高頻度に悪性腫瘍を併発する。その機序を明らかにするために、炎症巣の間質微細環境変化を遺伝子発現プロファイルの差異から抽出を試みた。間質組織マイクロダイセクションからのマイクロアレイ解析は条件が整わなかったが、炎症巣のin vitro再現系において潰瘍性大腸炎特異的発現を示す遺伝子CITED2を明らかにした。CITED2は炎症巣において早期に発現し、CBP/p300と協同してp53をアセチル化を介した安定化をもたらし、その下流分子の発現誘導を導きアポトーシスを惹き起こすことを明らかにした。潰瘍性大腸炎炎症巣においてもそのCITED2発現は炎症の活動性と相関していた。潰瘍性大腸炎においては腸内細菌が産生する酪酸によってCITED2-p53系が活性化して上皮細胞の細胞死・びらんを来し、その炎症のトリガーとなっている可能性が明らかになった
