Research Abstract

細胞老化誘導シグナロソームRas/ERα/MDM2/p53/p21の破綻は不死化能獲得に関与する。様々ながん細胞で本シグナロソームを再構築するとがん細胞に老化が誘導される。癌細胞に本シグナロソームを再構築するためSP1阻害剤低濃度Mithramycin(MTH)を用い、MDM2発現抑制及びp53蛋白安定化することを試みた。20nM MTHはp53遺伝子野生型Hec6, HHCIA, KF, OVAS21がん細胞増殖を抑制したが変異型p53遺伝子を持つがん細胞の増殖は抑制しなかった。SubG1及びG0/G1への集積が認められた。p53遺伝子下流のPUMA及びp21発現誘導も観察された。MTH処理後MDHたんぱく発現は抑制されたが、p53蛋白安定化に伴う二次的MDM2蛋白発現誘導が観察された。ヌートマウス皮下移植実験にてMTHは高濃度で軽度な腫瘍形成抑制を示した。一時的p53蛋白の安定化はルシフェレースリポーターアッセイで確認された。低濃度MTHの抗腫瘍効果を増強するためMDM2阻害剤nutlin3との併用を行った。顕著なアポトーシス誘導を伴った腫瘍抑制効果が示された。
