ヒトMR(ミネラルコルチコイド受容体)、GR(グルココルチコイド受容体)、AR(アンドロゲン受容体)、またはPR(プロゲステロン受容体)を過剰発現するヒト胚腎HEK293細胞由来の細胞溶解液を受容体−リガンド競合結合アッセイのために使用してKi値を決定する。典型的な方法を以下に提供する。
筋組織中のアゴニスト活性の指標として、C2C12 AR/AREレポータアッセイを実施する。手短には、マウス筋芽細胞であるC2C12細胞をFugene(商標)試薬を使用してコトランスフェクトする。GRE/ARE(グルココルチコイド応答エレメント/アンドロゲン応答エレメント)およびルシフェラーゼレポータcDNAの上流のTKプロモータを含有するレポータプラスミドは、ウイルスCMVプロモータを使用してヒトアンドロゲン受容体(AR)を構成的に発現するプラスミドを用いてトランスフェクトする。細胞は、T150cm2のフラスコ内で4%のCS−FBSを含むDMEM培地中でトランスフェクトする。5時間のインキュベーション後、トランスフェクトした細胞をトリプシン化し、96ウエルプレート内の4%のCS−FBSを含有するDMEM培地中でプレーティングし、2時間インキュベートし、その後約0.01nM〜10μMの範囲内の様々な濃度の試験化合物に曝露させる。化合物との24時間のインキュベーション後、細胞を溶解させ、ルシフェラーゼ活性を標準技術によって決定する。データを4パラメータ適合計算法に当てはめてEC50値を決定する。有効率(%)は、10nMのメチルトリエノロンを用いて得た最高刺激に比較して決定する。
性腺機能低下症誘発性の筋肉減弱性筋萎縮症は、加齢、癌、悪液質、敗血症、除神経、不使用、不活動、熱傷、HIV後天性免疫不全症候群(AIDS)、慢性腎または心不全、無負荷/微少重力、および筋ジストロフィなどを含む様々な疾患状態の結果として発生する可能性がある。これらの様々な条件下で筋肉消失をもたらす一連の事象は様々であるが、集合的には筋肉同化および筋肉異化経路における不均衡をもたらすので、筋肉の質量および機能の正味消失が存在し、これは遅延性ラット性腺摘出モデルにおいて肛門挙筋(LA)および球海綿体筋(BC)会陰筋湿重量における変化を介して測定することができる。
HDL(高密度リポタンパク質)コレステロールにアンドロゲン受容体調節剤が及ぼす作用を評価するために実施する本試験のためにはカニクイザル(Cynomolgus monkeys)を使用する。この動物モデルは、HDLコレステロールを低下させることによってアンドロゲンに応答することが証明されており、ヒトにおける同一応答が予測されると考えられてきた(Nantermet P.,et al,Endocrinol 149(4):1551−1561)。
