Outline of Annual Research Achievements

本研究は、ヒト腫瘍培養細胞で高発現を確認した機能性分子安定発現系を分子プローブのスクリーニングに利用し、ポストFDG製剤の有力候補である標識アミノ酸製剤のアミノ酸トランスポータ(AAT)及び薬物トランスポータに対する親和性の評価を目的とする。
DNAチップを用いて4万配列以上の遺伝子発現レベルを測定し、16種類のヒト腫瘍培養細胞における機能分子の遺伝子発現プロファイリングを直接比較可能なデータベースを構築した。このデータベースからAATの発現レベルが異なる数種のヒト腫瘍培養細胞を選択し、既に臨床使用されている11C-L-Metとその光学異性体11C-D-Metの細胞集積機序を検討した結果、L-体はsystem L、D-体ではsystem ASCの寄与も大きく、qPCRにより絶対定量したAAT発現量は細胞集積率と良い相関を示した(Nucl.Med.Biol,39:1213-1218,2012)。
また、ポストFDG 製剤の最有力候補である18F-FACBCの前立腺癌細胞への集積に関与を確認したAAT(J.Nucl.Med.,52:822-829,2011)について、単一発現細胞を作成して集積阻害を実施した結果、前立腺癌細胞で高発現を示したNa+依存性AATであるASCT2とSNAT2の内、FACBC はASCT2に高親和性を示した(Nucl.Med.Biol.,40:670-675,2013)。加えて18F-FACBCの癌細胞への集積に関与するアミノ酸トランスポータの薬剤誘導AAT発現との相関や細胞・炎症間の相異を比較検討した (アンドロゲン誘導前立腺癌:Mol.Imaging Biol.,16:756-764,2014,脳腫瘍:Brain Res.,1535:24-37,2013,炎症との比較:Mol.Imaging Biol.,16:322-329,2014)。
さらに、排泄型薬物トランスポータによる排泄機序解明のモデル化合物として、肝胆道系診断薬として臨床使用されている99mTc-PMTの胆汁排泄に関与するABCトランスポータの単一発現ベシクルを用いて検討し、P-glycoprotein(P-gp)及びMRP2の関与が明らかにした(Nucl.Med.Biol.,41:338-342,2014)。
