hERGカリウムチャネルに対する化合物EXP1、TAK−438、及びEXP12の効果に関する研究
1)細胞培養:hERG細胞株を通常の培養で、10%ウシ胎児血清及び250μg/mLのG418を含有するDMEMにおいて継代した。
2)液体調製:全細胞パッチクランプ実験技術法で使用する細胞外液の成分(mM)は:NaCl 145;MgCl2 1;KCl 4;グルコース 10;HEPES 10;及びCaCl2 2であり、NaOHでpH値を7.4に調整し、スクロースで浸透圧を300mOsmに調整した。細胞内液の成分(mM)は:KCl 140;MgCl2 1;EGTA 5;HEPES 10;及びNa2ATP4であり、KOHでpH値を7.2に調整しスクロースで浸透圧を290mOsmに調整した。
1)電気生理学的記録:実験においてペトリ皿を取り出し、細胞外液で2回洗い、倒立の顕微鏡ステージに置いた。室温で全細胞パッチクランプ実験を行い、ホウケイ酸ガラスの微小電極先端の抵抗は3〜5MΩである。
2)電圧刺激策及び電流記録:全細胞記録モード確立後、膜電位を−80mVに抑え、30秒毎に細胞に+50mVの脱分極電圧刺激を与え、2秒間継続してから−50mVに再分極し、3秒間継続してhERGテール電流を出した。脱分極電圧刺激の前に、細胞に50msで−50mVの再分極電圧を与え、この電圧で記録される電流がhERGテール電流を計算するためのベースラインである。記録標準に達した細胞のみが実験対象化合物の検出に使用される。化合物を加える前に、hERGテール電流は細胞外液において少なくとも3分間安定に記録される。灌流投与後、hERGテール電流の振幅変動が<5%の場合、薬物効果が定常状態になったと認められる。電流が6分以内に定常状態にならない場合、当該濃度での化合物の検出も終了する。
3)検出基準:実験において膜抵抗が1,000MΩより大きい。初期電流が300pAより大きい。全細胞記録モード確立後、直列抵抗が12MΩより小さい。リーク電流がイオンチャネル電流の10%(−80pAは最大値)より小さい。
生データにはClampex10.2記録を使用し、*abfファイルに保存した。データ収集・分析にはpCLAMP10.1プログラムを使用した。化合物を加える前に電流が定常状態になった4〜5つのsweepを選出し、比較用電流の振幅として平均ピークを算出した。化合物を加えた後に電流が定常状態になった4〜5つのsweepを選出し、電流が抑制された後の残りの振幅として平均ピークを算出した。実験対象化合物のhERG電流に対する抑制率は、以下の式に従って計算した。
%抑制率={1−(電流の残りの振幅)/(比較用電流の振幅)}*100
