Definitions
- the present invention relates to an aptamer for autotaxin and a method for using the aptamer.
- Autotaxin is a secreted protein that has been identified as a molecule that enhances the motility of melanoma cells. It belongs to the Enpp (electronucleotide phosphophosphate / phosphodiesterase) family protein and is also known as Enpp2. It has phosphodiesterase activity and is involved in extracellular nucleotide metabolism. It is also an enzyme that has LysoPhospholipase D activity (LysoPLD activity) and decomposes lysophosphatidylcholine (LPC) into lysophosphatidic acid (LPA) and choline. The produced LPA exhibits various physiological activities such as cell motility activation, cell proliferation, and angiogenesis as a lipid mediator.

- the aptamer of the present invention can be synthesized by the disclosure in the present specification and a method known per se in the art. For example, it can be synthesized by using DNA polymerase.
- a DNA having a target sequence is chemically synthesized, and this is used as a template to amplify by a polymerase chain reaction (PCR) which is a known method.
- PCR polymerase chain reaction
- This is converted into a single strand by a known method such as polyacrylamide electrophoresis, enzyme treatment such as ⁇ exonuclease, a method using streptavidin-biotin interaction and alkali treatment, or the like.
- the efficiency of the extension reaction can be increased by using a polymerase having a mutation introduced at a specific position.
- the aptamer thus obtained can be easily purified by a known method.
- Aptamers can be synthesized in large quantities by chemical synthesis methods such as the amidite method or the phosphoamidite method. The synthesis method is well known and is described in Nucleic Acid (Vol. 2) [1] Synthesis and Analysis of Nucleic Acid (Editor: Yukio Sugiura, Hirokawa Publishing Company, etc.). In practice, a synthesizer such as OligoPilot 100 or OligoProcess manufactured by GE Healthcare Bioscience is used.
- Aptamers can add functional substances after synthesis by introducing an active group such as an amino group during chemical synthesis such as the phosphoramidite method. For example, by introducing an amino group at the end of the aptamer, a polyethylene glycol chain having a carboxyl group introduced can be condensed. Aptamers bind to a target substance by various binding modes such as ionic bonds using the negative charge of the phosphate group, hydrophobic bonds and hydrogen bonds using ribose, hydrogen bonds using nucleobases and stacking bonds.
- the ionic bond utilizing the negative charge of the phosphate group that exists in the number of constituent nucleotides is strong and binds to the positive charge of lysine or arginine present on the surface of the protein.
- nucleobases that are not involved in direct binding to the target substance can be substituted.
- the stem structure portion is already base-paired and faces the inside of the double helix structure, so that the nucleobase is difficult to bind directly to the target substance. Therefore, the activity of the aptamer is often not reduced even if the base pair is replaced with another base pair.
- Aptamers can be produced by using the DNA-SELEX method and its improved methods (for example, Stephen Fitter and Robert James, J. Biol. Chem., 280 (40), 34193-34201 (2005), etc.). .
- SELEX method by increasing the number of rounds or using a competing substance to tighten the selection conditions, aptamers having a stronger binding power to the target substance are concentrated and selected. Therefore, by adjusting the number of rounds of SELEX and / or changing the competition state, aptamers with different binding strengths, aptamers with different binding modes, binding strengths and binding modes are the same, but base sequences are different. Aptamers may be obtained.
- the SELEX method includes an amplification process by PCR. By introducing a mutation by using manganese ions in the process, it becomes possible to perform SELEX with more diversity.
- Aptamers obtained by SELEX are nucleic acids having high affinity for the target substance, but this does not mean that the physiological activity of the target substance is inhibited.
- Autotaxin is a basic protein, and it is considered that nucleic acids are likely to bind non-specifically, but does not affect the activity of the target substance other than aptamers that bind strongly to specific sites. In fact, RNA containing a random sequence used as a negative control did not bind to or inhibit autotaxin.
- SELEX can be carried out by further changing the primer in order to obtain an aptamer having higher activity.
- a template in which a part of an aptamer having a certain sequence is made into a random sequence or a template in which about 10 to 30% of a random sequence is doped is prepared, and SELEX is performed again.
- the aptamer obtained by SELEX has a length of about 80 nucleotides, and it is difficult to make it as a medicine as it is. Therefore, it is necessary to repeat trial and error to shorten the length to about 50 nucleotides or less that can be easily chemically synthesized.
- the aptamers obtained by SELEX vary in ease of subsequent minimization work depending on the primer design. If the primer is not designed well, even if active aptamers can be selected by SELEX, subsequent development becomes impossible. In the present invention, an aptamer having an inhibitory activity even at about 30 nucleotides could be obtained.
- Aptamers are easy to modify because they can be chemically synthesized. Aptamers use the MFOLD program to predict secondary structures, predict three-dimensional structures by X-ray analysis or NMR analysis, which nucleotides can be replaced or deleted, and where new nucleotides can be found. Can be estimated to some extent. The aptamer of the predicted new sequence can be easily chemically synthesized, and whether or not the aptamer retains the activity can be confirmed by an existing assay system.
- the activity often changes even if a new sequence is added to both ends of the sequence. do not do.
- the length of the new sequence is not particularly limited.

Abstract
Description
最近、ブレオマイシン誘導による肺線維症モデルにおいて、LPA受容体LPA1のノックアウトマウスやLPA1阻害剤による線維化抑制効果が報告され、LPAと肺線維症との関わりが示唆されており、LPAの産生酵素であるオートタキシンについても肺線維症との関わりに注目が集まっている。
その中で抗オートタキシンモノクローナル抗体が間質性肺炎および/または肺線維症に対する予防および/または治療効果を有することが報告された。またオートタキシン低分子阻害剤によりブレオマイシン誘導による肺線維症モデルにおいての線維症抑制効果も報告された。いずれの報告でも、特発性肺線維症患者の肺胞洗浄液中にオートタキシンが存在し、健常人と比較してその濃度や活性が高いことが示されている。
特発性肺線維症は5年生存率が30%という極めて予後の悪い疾患である。そのメカニズムは不明な点が多いが、一般的に肺胞などが損傷を受けることで、組織修復機構が過剰に働き、肺間質部において、線維芽細胞の異常増殖や結合組織タンパク質の過剰生産が起こるとされている。現在、世界的な標準治療としてステロイド、免疫抑制剤などが使用されているが、2008年、世界に先駆けて日本において特発性肺線維症の治療薬として、ピレスパ(一般名:ピルフェニドン)が承認され、その有効性などが臨床の場でも検討されている。しかし、ピレスパが何を標的としているのかなど、その作用機序は不明な点が多い。
アプタマーは標的分子との結合特性が高く、同様な機能をもつ抗体と比較してもその親和性は高い場合が多い。さらに免疫排除を受けにくく、抗体特有の抗体依存性細胞障害(ADCC)や補体依存性細胞障害(CDC)などの副作用は起こりにくいとされる。デリバリーの観点では、アプタマーは抗体の1/10程度の分子サイズであるため組織移行が起こりやすく、目的の部位まで薬物を送達させることがより容易である。また同じ分子標的医薬の低分子においては、中には難溶性のものもあり、その製剤化には最適化が必要である場合もあるが、アプタマーは水溶性が高いため、その点でも有利である。さらに化学合成により生産されるので、大量生産すればコストダウンを図ることができる。その他、長期保存安定性や熱・溶媒耐性もアプタマーの優位な特徴である。一方で、一般にアプタマーの血中半減期は抗体よりも短い。しかし、この点も毒性を考慮した場合はメリットとなる場合がある。
2004年12月には世界初のRNAアプタマー医薬であるMacugenが加齢黄斑変性症の治療薬として米国で承認されており、RNAアプタマーの治療薬、診断薬、試薬への応用が注目され、次世代医薬品として期待されている。
アプタマーはRNAアプタマーが広く検討されてきたが、RNAは生体内で不安定であり製造コストが高いことから、近年では、生体内で安定であり、かつ安価に製造できるDNAアプタマーの研究開発も進められている(非特許文献1~2)。

で表わされる配列は、式(IV):
本発明のアプタマーが種々の活性を有するためには、上記潜在的2次構造で示されるようなステム-ループ構造が維持されることが望ましい。ステム構造は相補的な塩基対によって形成されるが、塩基対の数は特に限定されない。またステム構造においては、全体としてステム構造を構成する限りにおいて、その一部において塩基対を形成しなくてもアプタマー活性は維持される。
また糖残基については、2’位及び4’位で架橋構造を形成したBNA:Bridged nucleic acid(LNA:Linked nucleic acid)とすることもできる。このような糖残基の改変も、自体公知の方法により行うことができる(例えば、Tetrahedron Lett., 38, 8735-8738 (1997); Tetrahedron, 59, 5123-5128 (2003)、Rahman S.M.A., Seki S., Obika S., Yoshikawa H., Miyashita K., Imanishi T., J. Am. Chem. Soc., 130, 4886-4896 (2008)など参照)。
なかでもリン酸基たるP(O)O基の少なくとも一つが、P(O)S(チオエート)、P(S)S(ジチオエート)またはP(O)R、P(O)OR’(R又はR’は、置換されていないアルキル基である)で置換されている、いわゆるホスホロチオエート化、ホスホロジチオエート化、P-アルキル化またはP-アルコキシ化したものが好ましい。アプタマーに含まれるリン酸基の少なくとも一つがホスホロチオエート化、ホスホロジチオエート化、P-アルキル化またはP-アルコキシ化されることによって、本発明のアプタマーの活性が向上する。
ここで、特にP-メチル化またはP-アルコキシ化されたリン酸基は、共通配列の一部に導入されることが好ましい。このような疎水性の高い官能基(以下、「疎水性基」と記載)が共通配列部分に導入されることが、本発明のアプタマーがオートタキシンと直接作用して阻害活性を向上させるのに効果的である。疎水性基としては、本発明のアプタマーのオートタキシンに対する阻害活性が向上する限り特に限定されないが、アルキル基もしくはアルコキシ基が好ましいものとして挙げられる。アルキル基としては、メチル基、エチル基、プロピル基などが挙げられ、アルコキシ基としては、メトキシ基、エトキシ基、イソプロポキシ基、ブトキシ基、プロポキシ基などが挙げられる。

改変はまた、キャッピングのような3’及び5’の改変を含んでもよい。
アプタマーはアミダイト法もしくはホスホアミダイト法などの化学合成法によって大量合成することができる。合成方法はよく知られている方法であり、Nucleic Acid(Vol.2)[1]Synthesis and Analysis of Nucleic Acid(Editor:Yukio Sugiura,Hirokawa Publishing Company)などに記載のとおりである。実際にはGEヘルスケアーバイオサイエンス社製のOligoPilot100やOligoProcessなどの合成機を使用する。精製はクロマトグラフィー等の自体公知の方法により行われる。
アプタマーはホスホアミダイト法などの化学合成時にアミノ基などの活性基を導入することで、合成後に機能性物質を付加することができる。例えば、アプタマーの末端にアミノ基を導入することで、カルボキシル基を導入したポリエチレングリコール鎖を縮合させることができる。
アプタマーは、リン酸基の負電荷を利用したイオン結合、リボースを利用した疎水結合及び水素結合、核酸塩基を利用した水素結合やスタッキング結合など多様な結合様式により標的物質と結合する。特に、構成ヌクレオチドの数だけ存在するリン酸基の負電荷を利用したイオン結合は強く、タンパク質の表面に存在するリジンやアルギニンの正電荷と結合する。このため、標的物質との直接的な結合に関わっていない核酸塩基は置換することができる。特に、ステム構造の部分は既に塩基対が作られており、また、二重らせん構造の内側を向いているので、核酸塩基は、標的物質と直接結合し難い。従って、塩基対を他の塩基対に置換してもアプタマーの活性は減少しない場合が多い。ループ構造など塩基対を作っていない構造においても、核酸塩基が標的分子との直接的な結合に関与していない場合に、塩基の置換が可能である。デオキシリボースの2’位の修飾に関しては、まれにデオキシリボースの2’位の官能基が標的分子と直接的に相互作用していることがあるが、多くの場合無関係であり、他の修飾分子に置換可能である。このようにアプタマーは、標的分子との直接的な結合に関与している官能基を置換又は削除しない限り、その活性を保持していることが多い。また、全体の立体構造が大きく変わらないことも重要である。
オートタキシンに結合したDNAはPCRで増幅後、エキソヌクレアーゼ(BioLabs社)によって一本鎖DNAを処理した。その後、λエキソヌクレアーゼ(BioLabs社)で処理することにより、二本鎖DNAを一本鎖DNAにし、その一本鎖DNAを次のラウンドのプールとして用いた。

測定結果を表1に示した。測定の結果、配列番号4~10はオートタキシンに結合することがわかった。またネガティブコントロールとして使用した40ヌクレオチドのランダム配列を含む1ラウンド目に使用した配列番号1で表される核酸プール(40N)は、結合量が最も多かった配列番号10の10%以下であり、結合しない(“-”とした)ことがわかった。ここで結合量とは最大のレゾナンスユニット(RU)値を示す。
またこれらの核酸がオートタキシン阻害活性を示すかどうかを、下記の方法により評価した。オートタキシンの基質として、ホスホジエステル結合含有合成基質 p-nitrophenyl thymidine 5’-monophosphate(pNP-TMP)(SIGMA)を選択した(以下、NPP2阻害アッセイという)。加水分解によりホスホジエステル結合が切断され、p-ニトロフェノールが遊離する。このp-ニトロフェノールは黄色く発色し、それを検出する。アッセイには96ウェルプレート(6-Well EIAsurasshuRIA Polystyrene Plates、 Costar社)を使用し、反応液量200μLで行った。なお、反応液として溶液Aを用いた。核酸を溶液A 100μL中に用意し、そこに同じく反応液A中で10mMに調整したpNP-TMP 20μLを添加しよく混合した後、37℃で5分間加温した。一方で6ngのオートタキシンを溶液Aで希釈したものを80μL用意し、37℃で5分間加温した。加温後両者を混合し酵素反応を開始させた。反応溶液中の最終オートタキシン濃度は0.3nM、最終基質濃度は1mMである。反応液を含むプレートを37℃で24時間加温後、マイクロプレートリーダーSpectraMax190(モレキュラーデバイス社製)にセットし、波長405nmで吸光度を求めた。核酸をいれていないときの吸光度を100%(A0)とし、各被験物質の吸光度(A)から阻害率を次式から求めた。
配列番号5で表されるヌクレオチド配列を有するアプタマーの短鎖化と塩基置換を行った。改変体の配列を配列番号11~16に示す。これらのうち配列番号11および12で表されるアプタマーの二次構造予測を図2に示す。図中、共通配列部分のヌクレオチドを丸(○)で囲った。またX1~X4に該当するヌクレオチドを点線の丸(○)で囲った。特に言及がなければ、以下に挙げられる個々の配列は、5’から3’の方向で表し、全てデオキシリボヌクエレオチドを示す。

測定結果を表2に示した。表2では結合量が配列番号12で表されるヌクレオチド配列を有するアプタマーの10%以下であるものを結合しない(-)とし、それ以上のものは結合する(+)とした。ここで結合量とは最大のレゾナンスユニット(RU)値を示す。その結果、配列番号11~14および16で表されるヌクレオチド配列を有するアプタマーはオートタキシンに結合することが分かった。
さらに配列番号15は共通二次構造1の上部ステムが欠損していた。このため、活性が大きく低下したと考えられる。

反応溶液量は36μLとし、測定方法は下記のように行った。溶液Aで調製した14:0LPCが最終濃度0.5mMになるように添加されたヒトプール血清(コージンバイオ社製)33μLに溶液A3μL中に溶解したアプタマーを添加し(最終血清濃度は約92%)、37℃で加温した。3時間後にオートタキシン活性を停止させるため、100mM EDTA溶液を4μL加えた後、LPA濃度測定を行った。LPA濃度測定はKishimotoらの方法(Kishimoto、Clinica Chimica Acta 333,59-69,2003)で行った。アプタマーの代わりに溶液Aを加えた血清中で産生されるLPA濃度をコントロール(L0)とし、アプタマーを加えた血清中のLPA濃度(L)から各アプタマーの阻害率を次式から求めた。
配列番号12(48)で表わされるアプタマーがFGF2(ぺプロテック社)に対して結合活性を有しているかどうか表面プラズモン共鳴法で確認した。測定には、GEヘルスケア社製のBiacore T100を用い、以下に示す方法で測定を行った。CM4チップのセンサーチップ表面に、アミノカップリングキットを使用し、約2700RUのオートタキシンをフローセル2に固定化、FGF2をフローセル3に固定化した(約1100RU)。流速20μL/minで、アナライトとして0.3μMに調製した核酸を20μLインジェクトした。ランニングバッファーには溶液Aを用いた。
測定の結果、配列番号12(48)で表されるアプタマーはFGF2には結合しないことがわかった(図3)。これは本発明のアプタマーがオートタキシンに特異的に結合することを示している。
実施例4で作製した配列番号12(48)で表わされるアプタマーをブレオマイシン誘導型肺線維症モデルマウスに腹腔内投与し、その効果を検証した。
ICR系SPFマウス(10週齢、雄、日本チャールズリバー)に対し、PBSで770μg/mLに調製したブレオマイシン50μLを麻酔下、気管内投与した。ブレオマイシンを投与した翌日から毎日1回、1mM塩化マグネシウム入りPBSに溶かしたオートタキシンアプタマー溶液、又は1mM塩化マグネシウム入りPBSのみ(ビークル群)を1回の投与量100μLを腹腔内投与した。アプタマー投与量は1および3mg/kg/日の2用量とした。また、無処置のコントロール群も同じ試験期間飼育した。ブレオマイシン投与後から21日目に試験を終了し、肺を摘出、左肺をヒドロキシプロリン測定用に凍結保存した。ヒドロキシプロリンの測定はバイオビジョン社のHydroxyproline Colorimetric Assay キットを用いて測定した。
以上より、配列番号12(48)で表わされるアプタマーは肺線維症治療薬として使用可能であることが示唆された。
配列番号12(144)および12(149)で表されるアプタマーがオートタキシンのリゾホスホリパーゼD活性を阻害するかどうか、下記の方法により評価した。オートタキシンの基質として14:0リゾホスファチジルコリン(LPC、Avanti社)を選択した(以下LysoPLD阻害アッセイとした)。LPCはオートタキシンがもつリゾホスホリパーゼD活性により加水分解され、リゾホスファチジン酸(LPA)とコリンに分解される。コリンはコリンオキシダーゼにより酸化され過酸化水素が産生する。この過酸化水素とペルオキシダーゼ存在下でN-エチル-N-(2-ヒドロキシ-3-スルホプロピル)-3-メトキシアニリン(TOOS)と4-アミノアンチピリン(4-AA)が酸化縮合反応を起こし、紫色に呈色するのを検出する。

実施例5において、1ヶ所のみP-メチル修飾された改変体を作製し、LPA産生阻害実験で阻害活性を確認した。その結果、配列番号12(24)で表されるアプタマーの12番目のCと13番目のCの間のリン酸基にP-メチル修飾を加えることで活性が向上することがわかった。12番目のCと13番目のCは共通配列の一部なので、メチル基がオートタキシンと直接作用して阻害活性が向上したと推測された。そこで、メチル基よりも大きく、疎水性の高い官能基を導入することで阻害活性が更に向上するかどうか検討した。
配列番号12(24)で表されるアプタマーの12番目のCと13番目のCの間のリン酸基を修飾したアプタマーを化学合成で作製した。それらの配列を配列番号12(150)~12(152)に示す。特に言及がなければ、個々の配列はデオキシリボヌクレオチドであり、5’から3’の方向で表す。ヌクレオチドにおける括弧はその2’位の修飾を示し、Mはメトキシ基を示す。CαC、CβC及びCγCはリン酸基の部分を修飾したもので、順にP-イソプロポキシ化、P-プロポキシ化、P-ブトキシ化されたものを示す(下記構造式を参照)。末端修飾におけるidTはinverted-dTを示す。
