Research Abstract	ヒトOTC遺伝子を持つAAVのvector plasmidとしてITR-ITR間が5.35kbでTK-neo遺伝子を持つもの(以下OTC2)と、4.4kbでTK-neoを持たないもの(以下OTC3)の2つを作製した。これらのconstructionをscreeningする目的でリン酸カルシウム法を用いてそれぞれのベクターをpackaging plasmidとともにHeLa細胞にco-transfectionし、野性株アデノウイルスを感染させて、AAVを作製した。OTC2を用いて作製したAAV(以下AAV/OTC2)は3T3細胞を用いて力価測定したところ、10^4cfu/mlであった。一方、OTC3を用いて作製したAAV(以下AAV/OTC3)をdot blot法によりperticle数を測定したところ10^5perticles/mlであった。AAV/OTC2及びAAV/OTC3をそれぞれを2mlずつ10^6個のHepG2細胞にtrunsductionしOTC活性を測定したところ、前者では測定感度以下であったが、後者では1.265μmol/mg protein/hrの活性が得られた。そこで、AAV/OTC3を150ml作製し、硫酸セルロースカラムを用いて濃縮したものを20μl用い、10^6個のHepG2細胞にtransductionしたが0.144μmol/mg protein/hrの活性しか得られなかった。現在、OTC2とpackaging plasmidのpackaging cell lineを作製中であり、より高い力価のAAV/OTCを作製を目指している。
