Research Abstract

p53研究の進歩により、ゲノムの守護神としての癌抑制機能以外にも実に多彩な生理作用を発揮することがわかってきた。それは主にp53が転写因子として機能し、生理作用の異なる様々な下流遺伝子群を、細胞の種類や細胞環境の変化に応じて、時間的・空間的・選択的に巧妙に使い分けているからである。今回ゲノムワイドの解析から、細胞内代謝制御に関わるp53下流遺伝子GLS2を同定することに成功した。さらに、その肝臓腫瘍組織における発現低下と腫瘍細胞増殖抑制効果を証明し、p53の癌抑制機能を担うことをProc.Natl.Acad.Sci.USA.誌に報告した。またクロマチンの構造的・機能的調節機構に着目して、in vivoにおけるp53クロマチン複合体中に含まれる機能的会合分子群の同定とp53化学修飾の解析をプロテオミクスの手法を駆使して網羅的に試みた。その結果、p53のリン酸化・アセチル化・メチル化などの化学修飾や、クロマチン会合分子であるtranscriptional co-factor hSp110を同定した。Sp110の機能解析の結果、p53による細胞老化の制御を介して癌抑制機能に関連する可能性が示された。これらの新知見は、癌のエピジェネティック治療創薬における新規標的分子基盤の候補であり、確実な成果が成し遂げられた。
