A:細胞培養
HEK−hHCN1−2H10細胞を、225cm2フラスコ中、10%のFetalclone II+0.1mMの非必須アミノ酸+1mMのピルビン酸ナトリウム+10mMのHEPES+0.5mg/mLのG418を加えたMEM(アール塩を含む)において培養した。この細胞を、37℃、5%CO2雰囲気、相対湿度100%において50%コンフルエントになるまで通常とおりに維持した。使用の24時間前に、細胞を30℃において温置してHCN1膜発現を増加させ、パッチクランプ実験の直前に採取した。増殖培地を真空吸引し、細胞を50mLのダルベッコリン酸緩衝食塩液(CaCl2およびMgCl2を含まない;D−PBS)中で洗浄した。次に、5mLの0.1%トリプシン/0.04%EDTAおよび細胞解離緩衝液(CDS)の1:1混合液とともに37℃において2分間温置することによって細胞を分離した。細胞の分離は5mLの増殖培地を添加することによって止めた。その後、10mLのピペットを使用して3−4回穏やかにかき回すことによって細胞を機械的に分離した。血球計数器を使用して細胞を計数し、1分半212gの遠心分離により回収し、5mLの濾過した外部記録溶液(下記参照)に再懸濁した。上記のとおりの遠心分離によって細胞を再度回収し、濾過した細胞外溶液に1mLあたり2×106細胞の密度で再懸濁し、4−5回かき回した。これらの細胞を、直ちにIonWorksに移した。
IonWorks Quattro(MDS Analytical Technologies)を使用して自動パッチクランプ記録を行った。IonWorks Quattroを細胞内(mM単位:グルコン酸カリウム、130;NaCl、10;MgCl2、1;EGTA、1;HEPES、10、pH7.35)および細胞外溶液(mM単位:グルコン酸カリウム、104;NaCl、10;KCl、30;MgCl2、1;CaCl2、1.8;Hepes、10;グルコース、5;pH7.35)記録溶液で満たした。穿孔パッチクランプ記録を(0.36%のDMSOに溶かした)0.1mg/mLのアンフォテリシンBとともに細胞電圧を−40mVに固定して確立した。全細胞穿孔パッチクランプ記録を2回の別々の実施において、1秒間の−80mVおよび−120mVの電圧ステップで行い、チャネル活性化前の電圧パルス−10mVを用いてリーク電流を差し引いた。化合物を12の濃度(0.5log間隔;1%DMSO)においてテストし、各電流記録間の10分間温置した。全細胞電流が100pS未満である、シール抵抗が<50MΩであるまたは実験過程においてシール抵抗が>50%変化した場合、細胞を除外した。化合物添加前後のHCNが媒介する時間依存性電流の振幅は、テスト電圧への移行時の容量過渡電流の直後に記録された電流と安定状態振幅に到達した後に記録された電流との差として測定された。データをIonWorks Quattro System Softwareバージョン2を用いて処理し、XLFit 4.1を用いたActivity Baseで標準的な4パラメータロジスティック関数を使用して解析した。濃度反応曲線を作製し、hHCN1チャネルにおける化合物の効力をpEC50として適切な信頼区間で報告した。
