EP1受容体拮抗作用確認試験
Rat Kidney BD Marathon-Ready cDNA(日本ベクトン・ディッキンソン株式会社)を鋳型として、配列番号1に示したフォワードプライマーおよび配列番号2に示したリバースプライマーを使用し、KOD-Plus-Ver2.0(東洋紡績株式会社)を用いて1回目のPCRを行った。さらに、この増幅産物を鋳型とし、配列番号3に示したフォワードプライマーおよび配列番号4に示したリバースプライマーを使用し、さらに同様に2回目のPCRを行った。2回目のPCRで得られた増幅産物をベクター(pcDNA3.1 D/V5-His-TOPO(登録商標)、インビトロジェン株式会社)に組み込んだ。常法により、この増幅産物を組み込んだベクターを大腸菌(ワンショットTOP10コンピテントセル、インビトロジェン株式会社)に導入し形質転換した。この形質転換した大腸菌をLB寒天培地にて1日培養した。培養後、コロニーを選択し、50μg/mLのアンピシリンを含むLB液体培地にて培養した。培養後、QIAprep Spin Miniprep Kit(株式会社キアゲン)を用いてベクターを精製した。このベクターの挿入部位の塩基配列(配列番号5)を公知のデータベース(NCBI)のアクセッション番号NM_013100で登録されているラットEP1の塩基配列(Ptger1)と比較したところ、1塩基以外全て一致していた。また、この塩基配列によって翻訳されたアミノ酸配列は、NCBIのアクセッション番号NP_037232で登録されているラットEP1受容体のアミノ酸配列と完全に一致した。したがって、クローニングした遺伝子配列はラットEP1受容体の塩基配列であり、得られたアミノ酸配列はラットEP1受容体であることが確認された。配列番号5に示した核酸が挿入されたpcDNA3.1 D/V5-His-TOPO(登録商標)をラットEP1発現ベクターとした。
COS-1細胞(大日本住友製薬)は抗生物質としてペニシリン-ストレプトマイシン溶液(インビトロジェン株式会社、最終濃度:ベンジルペニシリンとして100U/mL;ストレプトマイシンとして100μg/mL)、MEM非必須アミノ酸(インビトロジェン株式会社、最終濃度:0.1mM)および胎児牛血清(三光純薬株式会社、最終濃度:10%)を添加したD-MEM液体培地(高グルコースおよびL-グルタミン含有、インビトロジェン株式会社)を用いて、5%CO2ガス条件のインキュベーター内で37℃にてコンフルエントに達するまで培養した。
コンフルエントに達した細胞を0.05%トリプシン/0.53mM EDTA・4Na(インビトロジェン株式会社)にて剥がし、上記液体培地にて再懸濁した。再懸濁した細胞を上記液体培地にてスプレットレシオが1:4から1:8になるように希釈し、培養した。
コンフルエントに達した細胞を0.05%トリプシン/0.53mM EDTA・4Naにて剥がし、MEM非必須アミノ酸(最終濃度:0.1mM)及び胎児牛血清(最終濃度:10%)を添加したD-MEM液体培地(高グルコース及びL-グルタミン含有、インビトロジェン株式会社)にて再懸濁した。この再懸濁した細胞懸濁液をポリD-リジンコートした96ウェルマイクロプレート(BD BioCoat(登録商標)、日本ベクトン・ディッキンソン株式会社)の各ウェルに細胞数5×104個/ウェル、液体培地量が100μLになるように調製し、播種した。播種後、その細胞を5%CO2ガス条件のインキュベーター内で37℃にて培養した。このラットEP1発現ベクターの導入用細胞が接着した時点(播種後約2時間後)に下記に示す手順でラットEP1発現ベクターの導入を行った。
ラットEP1発現ベクターの導入のために、リポフェクタミン2000(インビトロジェン株式会社)を使用した。ラットEP1発現ベクターを200ng/25μL/ウェルになるようにOPTI-MEM(登録商標) I Reduced-Serum Medium(インビトロジェン株式会社)にて希釈した。同時に、リポフェクタミン2000(インビトロジェン株式会社)を0.5μL/25μL/ウェルになるように、OPTI-MEM(登録商標) I Reduced-Serum Medium(インビトロジェン株式会社)にて希釈し、室温にて5分間インキュベートした。5分間のインキュベート後、ラットEP1発現ベクター/リポフェクタミン2000の複合体形成のために、希釈したラットEP1発現ベクターと希釈したリポフェクタミン2000とを混合し、室温にて30分間インキュベートした。30分間のインキュベート後、ラットEP1発現ベクター/リポフェクタミン2000の複合体を上記ラットEP1発現ベクター導入用細胞に50μL/ウェルずつ分注した。このラットEP1発現ベクター/リポフェクタミン2000の複合体が分注された細胞を5%CO2ガス条件のインキュベーター内で37℃にて20時間培養した。20時間の培養後、この細胞をラットEP1受容体発現細胞として、細胞内カルシウム濃度の測定に使用した。
各試験化合物の10mMジメチルスルホキシド溶液をアッセイバッファー(20mM HEPES/Hank’s Balanced Salt Solution(HBSS)、pH7.2)にて希釈した。
ラットEP1受容体発現細胞をアッセイバッファーにて洗浄した。蛍光カルシウム指示薬(Fluo-4 NW Calcium Assay Kit(Molecular Probes):同製品プロトコールで調製、インビトロジェン株式会社、2.5mMプロベネシドを含む)100μLを各ウェルに添加し、37℃にて60分間、インキュベーター内にてインキュベートした。その後、細胞上清を全て吸引し、アッセイバッファーにて洗浄した。洗浄後、2.5mMプロベネシドを含むアッセイバッファー100μLを各ウェルに添加し、速やかに細胞内カルシウム濃度を測定した。
細胞内カルシウム濃度は、FlexStation(登録商標)(モレキュラーデバイス社製)を用いて蛍光シグナルとして測定した。蛍光シグナル読み込み開始から20秒後にアッセイバッファーで希釈した上記各試験化合物50μL(最終濃度:1nM~10μM)を各ウェルに添加し、60秒間蛍光シグナルを測定した。その後、50μLプロスタグランジンE2バッファー溶液を各ウェルに添加し(最終濃度10nM)、60秒間蛍光シグナルを測定した。
