Research Abstract

リンパ節転移のあるヒト口腔扁平上皮癌組織で発現の高いHOXC5, HOXC6およびHOXC8が, リンパ節転移に関与しているのかどうかを調べるために, 各HOX遺伝子の発現プラスミドベクターを構築した. 各々のHOX遺伝子発現ベクターをヒト口腔扁平上皮癌細胞株にリポフェクション法で導入し, 各HOX mRNAおよび蛋白の発現をRT-PCR法およびウエスタンブロット法で確認した. リンパ節転移に重要と考えられる癌細胞とリンパ管内皮細胞との相互作用を解析するために, ヒト皮膚から樹立されたリンパ管内皮細胞の同定を行った. 現在, HOX遺伝子を強制発現させた癌細胞のリンパ管内皮細胞への接着性ならびにリンパ管内皮細胞の培養上清に対する運動性などを検討している.
