第1の活性レベルを第2の活性レベルと定量的に関連づける段階であって、第1の活性レベルが第2の活性レベルよりも低い場合に前記化合物を前記ポリペプチドのアゴニストまたはアンタゴニストであると同定する段階。
前記ポリペプチドを発現する宿主を前記化合物と接触させる段階;
前記ポリペプチドの第1の発現レベルまたは活性を決定する段階;

Ultraspec(登録商標)RNA(Biotecx、テキサス州、ヒューストン)を用い製造業者の手順に従って全RNAを抽出し、DNase処理と共にRNAeasyミニキット(Qiagen、カリフォルニア州、バレンシア)を用いて精製した。T7-T24プライマーを用いて、SuperScript(商標)二本鎖cDNA合成キット(Life Technology、メリーランド州、ロックビル)により全RNA 10ugから二本鎖cDNAを合成した。フェーズロックゲル(phase lock gel)(Eppendorf、ニューヨーク州、ウェストベリー)を用いて、フェノール/クロロホルム/イソアミル抽出により二本鎖cDNA産物を精製した。インビトロ転写(IVT)MEGAscript(商標)T7キット(Ambion 、テキサス州、オースティン)を用いて二本鎖cDNAをさらにcRNAに変換し、ビオチン化ヌクレオチド1で標識した。RNAeasyミニキット(Qiagen、カリフォルニア州、バレンシア)を用いてインビトロ転写産物を精製し、記載されているように断片化した(Wodicka L, Dong H, Mittmann M, Ho MH, Lockhart DJ. Genome-wide expression monitoring in Saccharomyces cerevisiae. Nat Biotechnol 1997;15:1359-67)。製造業者(Affymetrix、カリフォルニア州、サンタクララ)が推奨するように、断片化したインビトロ転写産物のヒトゲノムU95(HG-U95)Genechip(登録商標)アレイセットへのハイブリダイゼーションを行った。
数値解析はすべて、AffymetrixのMASアルゴリズム(Affymetrix Technical Note:New Statistical Algorithms for Monitoring Gene Expression on GeneChip(登録商標) Probe Arrays (2001))によって報告されるようにシグナル強度について行った。実験におけるすべてのチップの全体的平均値に対してチップをそれぞれ標準化した。遺伝子は別々に標準化しなかった。
シグナル強度=BMI+組織+IR+血糖値+インスリン値+組織*IR+組織*血糖値+組織*インスリン値+誤差
