研究概要	メサンギウム細胞特異的高発現遺伝子、メグシンはセルピン(serine protease inhibitor)に属し、セリンプロテアーゼ活性阻害能を有することが示唆されている。そこでメグシンの生理活性を解明する目的で、メグシンリガンド(メグシンの標的セリンプロテアーゼ)の検索を行った。結果、メグシンは弱いながらいくつかの既知のセリンプロテアーゼの酵素活性を特異的に抑制することが明らかとなり、メグシンの機能の一端が明らかにされた。またメグシンの糸球体における機能を分子レベルで解明するために、メグシンTgと同腹野生型マウスからメサンギウム細胞を単離培養し、DNA chipによる発現遺伝子プロファイルを作製、両群において発現変動がみられる遺伝子群の検索を行った。予備的な解析結果から、いくつかの遺伝子、特にメサンギウム基質のリモデリングに関与するプロテアーゼや細胞増殖に関与する転写因子などの発現変動が確認でき、メグシンTgにおける腎炎自然発症(メサンギウム細胞増殖、メサンギウム基質増生、免疫複合体沈着)の分子機序解明の手がかりが得られた。さらにメグシンのメサンギウム細胞特異的転写機構の解明を目指して、転写開始点上流域約6キロの転写活性を解析したところ、この領域だけでは細胞特性を決定することができないものの、いくつかの既知の転写因子結合モチーフがメグシン転写レベルを制御していることが明らかとなった。このことから糸球体障害時のメグシン発現亢進機序解明の手がかりが得られた。
