肝細胞レベルでの脂肪の蓄積および放出に対する調節は、実際の脂肪肝の形成において非常に重要であり、従来の報告によれば、高脂肪食だけでなく、小胞体ストレスによっても組織内脂肪が蓄積され得ることが知られている。このような点に着目して、本発明者らは、小胞体またはゴルジ体ストレス(ER/Golgi stress)により活性化する転写因子の一つであるLeucine zipper protein(以下、LZIPと命名する。)と脂肪肝発病との相関関係の確認を試みた。これに先立って、本実施例では、LZIP処理によるlipoproteinの発現変化を確認し、これと関連したLZIP活性化のための条件および具体的な活性化部位を導き出すことを試みた。
肝細胞株HepG2で、LZIPの処理濃度によるApolipoprotein A4(以下、ApoA4と命名する)のプロモーター活性を測定し、その結果に基づいて、肝細胞株HepG2およびHuh−7を対象としてLZIPの処理または抑制によるApoA4 mRNAおよびタンパク質の発現量の変化の確認を試みた。以下の実施例で、上記LZIPの処理または発現のために、Flag−LZIP(N−末端にFlag epitope(DYKDDDDK)がtaggingされたLZIP配列をクローニングしたpCMV−3 Tag−1 vector)、またはAd−LZIP(C−末端にHA epitopeがtaggingされたLZIP配列をクローニングしたpShuttle−IRES−hrGFP−2 vector)を利用し、上記LZIPの抑制のためには、LZIP siRNA(配列番号5)を利用した。
前述したように、LZIPは、小胞体またはゴルジ体ストレス(ER/Golgi stress)により活性化する転写因子であって、小胞体の表面に付着しているタンパク質の一つである。本実施例では、より具体的に、ゴルジ体分裂物質であるBrefeldin A(BFA)、小胞体内の糖化プロセスを抑制するTunicamycin(TM)、小胞体内カルシウムを欠乏させるThasigargin(TG)でそれぞれ肝細胞を処理して、LZIPを活性化させた後、これに伴うApoA4の発現変化の確認を試みた。一方、対照群(Con)としては、1μlの100%メタノールで処理した群を利用した。
LZIP N末端のApoA4発現調節効果を直接的に確認するために、LZIP N末端をクローニングして、これを肝細胞株に発現させた後、これに伴うApoA4プロモーター活性、ApoA4 mRNAおよびタンパク質発現の変化を確認した。また、マウスの初代肝細胞を利用して、BFA処理によるLZIP N末端の分離の有無およびこれに伴うApoA4 mRNAおよびタンパク質発現変化を再度検証した。以下の実施例で、上記LZIP N末端処理または発現のために、Flag−LZIP−N(N−末端にFlag epitope(DYKDDDDK)がtaggingされたLZIP N末端配列をクローニングしたpCMV−3 Tag−1 vector)、またはAd−LZIP−N(C−末端にHA epitopeがタグされたLZIP N末端配列をクローニングしたpShuttle−IRES−hrGFP−2 vector)を利用した。
PI3K/Aktシグナル伝達系とこれらの抑制物質であるPTENシグナル伝達系は、脂肪肝の形成において非常に重要な役割をすると知られている。このため本実施例では、インビトロ キナーゼ アッセイ(in vitro kinase assay)およびGST プルダウンアッセイ(GST−pull down assay)を通じて、本発明のLZIP N末端とAktとの結合の有無を確認した。また、このような結果に基づいて、Akt阻害剤で処理することによるLZIP N末端タンパク質の量およびこれに伴うApoA4タンパク質の発現変化を確認した。
本実施例では、上記実施例1および2の結果に基づいて、肝組織内脂肪の蓄積、すなわち、脂肪肝の発病とLZIP N末端処理によるApoA4の発現変化との関連性を確認することを試みた。具体的には、ヒト肝細胞株であるHepG2またはマウス初代肝細胞に脂肪の蓄積を引き起こすオレイン酸(oleic acid;OA)と併用してLZIP N末端で処理した後、これらの肝細胞内脂肪の蓄積量をオレイン酸単独処理の場合と比較した。また、マウス動物モデルを対象としてLZIP N末端処理による肝組織内ApoA4発現量および脂肪の蓄積量の変化をin vivoで確認した。具体的には、LZIP N末端を含むウイルスを静脈注射を通じてマウスに投与し、その3日後、上記マウスから肝組織を摘出して、対照群(Ad−GFP)とApoA4の発現量、中性脂肪の比率などを比較分析した。
上記実施例3では、マウスの肝細胞またはマウスを対象として肝組織内脂肪の蓄積効果を確認することができた反面、本実施例では、ヒトでもこのような効果が観察されることができるか否かを確認しようと試みた。具体的には、肥満による脂肪肝、アルコール性脂肪肝、または非アルコール性脂肪肝組織を対象として正常肝組織とLZIPおよびApoA4発現量を比較した。
