C57BL/6系野生型(Wt)マウスおよびそのカルポニン1遺伝子ノックアウト(Cnn1−/−)マウス(いずれもオス、8週齢)の大動脈平滑筋細胞(SMC)を、コラゲナーゼ法により分離し、それぞれDMEM培地(FBS不含)中、37℃で48時間培養した。なお、Cnn1−/−マウスの作成は既に報告した(Genes Cells 3, 685-695, 1998)。培養系は、無処理系、血小板由来増殖因子(PDGF−BB)(10ng/ml)添加系、および低酸素系(O2 1%、CO2 5%、N2 94%)の3つで、それぞれの条件で24時間培養した後、常法により培養細胞抽出物を得て、ウエスタンブロッティングに供した。各蛋白に対する抗体は、カルポニン1抗体(Genes Cells 3, 685-695, 1998)、Hypoxia-inducible factor 1 alpha (HIF1α)抗体(Santa Cruz, sc-10790)、VEGF抗体(R & D systems, AF-493-NA)を用いた。
実施例1で説明したようにC57BL/6系Wtマウスから大動脈平滑筋細胞を分離し、これにカルポニンSiRNAを導入したものと、導入しないものを実施例1の無処理系と同じ培養系にて培養した(48時間、72時間)。マウスカルポニン1に対するSiRNAはDHARMACON社に注文して得た。リポソーム法(siLentFect・Bio-Rad社製)を用いて40nMのカルポニンSiRNAを細胞に導入した。細胞中のカルポニン1 mRNAおよびVEGF−A mRNAの発現、ならびにVEGF−A蛋白レベルを、リアルタイムPCR(定量的PCR)、ならびにELISA法により調べた。ELISAにはR&D SystemsのMouse VEGF Immunoassay (MMV00)を用いた。結果を図3に示す。
実施例1で用いたのと同じCnn1−/−マウスあるいはそのWtマウスの大動脈平滑筋細胞とルイス肺癌細胞(LLC)(RIKEN CELL BANK;RCB0558)を9:1の割合(1.1x107個/ml:1.2x106個/ml)で混合し、DMEM培地(FBS10%含)中、37℃で72時間培養し、馴化培地上清のVEGF−A蛋白量をELISAにて調べた。結果を図4に示す。Cnn1−/−マウス細胞とLLCを混合培養した上清中に分泌されたVEGF−A量は、Wtマウス細胞とLLCを混合培養した上清中に分泌されたVEGF−A量の約3倍であった。
