Research Abstract	HGFは私達が肝再生因子の実体として発見した増殖因子であるが、HGFは主に増殖制御や細胞運動の促進、形態形成の誘導などの機能を有するpleiotropic factorであり、肝臓や腎臓、肺など多くの組織・器官の形成や再生を担うorganotropic factorである。本年度はインジュリンの精製を進めるとともに,HGFの発現を調節するサイトカインの同定,HGFのさらに多様な働きが明らかになるとともに、HGF/インジュリンシステムからみた癌と宿主の相互作用の理解に貢献できる研究成果が得られた。 (1)インジュリンの精製とHGF発現調節ブタ肺からインジュリンの精製を進める過程でインジュリン活性を示す数種の画分を得た。そのうち2つの画分について精製すると、1つはIL-1であり、他の1つはヘパリンであることが明らかになり、ヘパリンやIL-1がHGF誘導活性を持つことを明らかにした。さらにインジュリンの逆作用を持つHGF発現抑制因子としてTGF-β1やグルココルチコイドが明らかになり、HGF発現がアクセルとブレーキにより巧妙に調節されていることが考えられた。現在さらに未知のタンパク質性のインジュリン活性の精製を進めている。 (2)新たに明らかになったHGFの生物活性 HGFは間葉に由来し上皮に働きかける因子と考えられてきたが、HGFが間葉組織由来細胞にも生物活性を発揮することを明らかにした。その1つは造血幹細胞の増殖促進作用ならびに血小板増加作用である。2つ目は前破骨細胞の増殖促進と破骨細胞への分化促進作用である。すなわちHGFにbone-remodeling作用があるという結果である。3つ目は関節軟骨の増殖と分化を強く促す作用である。 (3)インジュリン発現を介するがん細胞と宿主細胞との相互作用がん細胞の増殖能や浸潤転移能が宿主細胞の影響を強く受けていることは古くから知られている。このがん細胞と宿主細胞の相互作用をメディエートする液性因子の1つがHGFであることを明らかにした。がん細胞の中にHGF誘導因子(インジュリン様因子)を分泌するものが高頻度で検出された。がん細胞がインジュリン様因子を産生して宿主ストロマー細胞のHGF産生を促し、このHGFによりがん細胞の増殖能や浸潤能、線腔形成能が高まる可能性がある。HGFとそのインデュサーであるインジュリンをメディエーターとしてがんの増殖、悪性化などがん-宿主相関についての分子レベルの理解ができると考えている。
