Abstract
Description
ある実施態様において本発明は、2本鎖2次構造の1つ以上の領域を有する1本鎖DNAオリゴヌクレオチドを含む、核酸ポリメラーゼの可逆的阻害剤であって、前記領域の少なくとも1つが少なくとも1つのウラシル塩基を含む、前記可逆的阻害剤である。2本鎖2次構造は、PCR混合物中において周囲温度で安定であり得る。いくつかの実施態様において、可逆的阻害剤は配列番号1を有し、ここで、1つ以上のチミン塩基はウラシル塩基で置換される(例えば配列番号2〜4)。
定義
用語「核酸」及び「オリゴヌクレオチド」は、標的配列及びプローブを指す。これらの用語は長さにより限定されるのではなく、デオキシリボヌクレオチド(1本鎖又は2本鎖DNA)、リボヌクレオチド(RNA)、及びプリン又はピリミジン塩基(アデノシン、グアノシン、シチジン、チミジン、及びウリジンを含む)の任意の他のN−グリコシド、及びこれらの塩基の修飾物、の線状ポリマーの総称である。
5’-CGATCATCTCAGAACATTCTTAGCGTTTTGTTCTTGTGTATGATCG-3'
中の1つ以上のチミンをウラシルで置換することにより設計される。

U含有阻害剤オリゴヌクレオチド(U−アプタマー)の設計
既存のアプタマーNTQ21−46A(U0)(配列番号1):
5’-CGATCATCTCAGAACATTCTTAGCGTTTTGTTCTTGTGTATGATCG-3'
をdUをdTで置換することにより修飾して、以下のU−アプタマーを作成した:
5’-CGAUCAUCTCAGAACATTCTTAGCGTTTTGTTCTTGTGTAUGAUCG-3'
5’-CGATCATCTCAGAACATTCTTAGCGTTTUGUUCUUGTGTATGATCG-3'
5’-CGAUCAUCTCAGAACATTCTTAGCGTTTUGUUCUUGTGTAUGAUCG-3'
U−アプタマーの溶融温度の測定
U0、U1、U2、及びU3アプタマー(配列番号1、2、3、及び4)の溶融温度を、50mM トリスHCl、pH8.0、100mM KCl、1mM dNTP、2.5mM MgCl2、0.5×のSYBR(登録商標)Green I(Molecular Probes (Life Technologies、Inc.) Carlsbad、Cal.)、20nM DNAポリメラーゼZ05−D(記載される場合)、及び0.2μMのアプタマーの1つ、を含有する反応混合物中で測定した。溶融曲線分析を、製造業者の説明書に従ってLIghtCycler(登録商標)480(Roche Molecular Diagnostics, Indianapolis, Ind.)で行なった。結果は表1に示される。これらの結果は、TをUで置換することは、オリゴヌクレオチド2次構造の溶融温度を低下させることを示す。
UNGの存在下でのU−アプタマーの溶融温度の測定
U0、U1、U2、及びU3アプタマー(配列番号1、2、3、及び4)の溶融温度を、0.5U/μlのUNGを添加したと記載されている場合以外は、実施例1に記載の反応混合物中で測定した。UNG切断を可能にするために、すべての反応混合物を37℃でインキュベート後、溶融曲線分析を行なった。結果は表2に示される。結果は、TをUで置換し次にUNGで切断することが、オリゴヌクレオチド2次構造の溶融温度を実質的に低下させることを示す。
異なる温度におけるU−アプタマーとUNGの存在下でのプライマー伸長
オリゴヌクレオチド阻害剤の存在下のDNAポリメラーゼ活性を、種々の濃度のU0、U1、U2、又はU3アプタマー(配列番号1、2、3、及び4)の存在下のプライマー伸長により測定した。このアッセイは、以下の配列(配列番号5)を有するオリゴヌクレオチドでプライムしたM13 mp18 1本鎖DNA(M13;GenBank Accession No. X02513)を使用して行なった:
5'-GCGCTAGGGCGCTGGCAAGTGTAGCGGTCAC-3'。
U−アプタマーとUNGの存在下のKRASコドン12標的のリアルタイムPCR増幅
本例では、種々の濃度のU0、U1、U2、又はU3アプタマー(配列番号1、2、3、及び4)の存在下で、ヒトDNA中のKRAS標的の増幅が行われる。KRAS標的の性質は、これを、プライマーダイマー化と非特異的増幅を特に受けやすいものにしている。ホットスタートが無い場合、非特異的増幅は、標的の濃度の差をあいまいにし、定量分析を不可能にする。本例では、KRAS標的の連続10倍希釈物を加えて、本方法の定量範囲と特異性を評価した。増幅は、3mM MgCl2、50mMトリシン、pH8.0、55mM酢酸カリウム、各200μMのdATP、dCTP、及びdGTP、300μM dUTP、30μM dTTP、20nMのZ05DNAポリメラーゼ、及び0.2×のSYBR(登録商標)Green I (Life Technologies, Carlsbad, Cal.)、及び記載される場合UNGを含有する反応混合物中で行なった。LightCycler装置の温度プロフィールは、95℃で15秒、50、55、又は60℃で40秒を50サイクル行なった。増幅は、種々の濃度のU0、U1、U2、又はU3アプタマー(配列番号1、2、3、及び4)の存在下でCt値を測定することにより検出した。Z05 DNAポリメラーゼに対してアプタマーが0、10、100、又は200×モル過剰で存在することを確実にするために、試験したアプタマーの濃度範囲は、0、200、1000、及び2000nMであった。結果は表3〜6に示される。
U−アプタマーとUNGの存在下のRNAのRT−PCR増幅
本例では、実施例5に記載されたように、標準的PCR条件下で、UNGを含有する反応混合物中で、種々の濃度のU0、U1、U2、又はU3アプタマー(配列番号1、2、3、及び4)の存在下で、RNA標的(HVC JP2〜5、反応毎に1000コピー)の増幅を行なった。試験したアプタマーの濃度範囲は、Z05 DNAポリメラーゼに対して0、100倍、及び200倍モル過剰であった。結果は表7に示される。
