また、本発明は、白血病幹細胞マーカー遺伝子の発現を抑制し得る物質または当該遺伝子の翻訳産物の活性を抑制し得る物質を有効成分として含有する、白血病幹細胞を標的化した急性骨髄性白血病の治療剤を提供する。
以下、有効成分について説明する。
アンチセンス核酸の種類はDNAであってもRNAであってもよいし、あるいはDNA/RNAキメラであってもよい。アンチセンス核酸は、天然型のリン酸ジエステル結合を有するものであっても、分解酵素に安定なチオリン酸型(リン酸結合のP=OをP=Sに置換)や2’-O-メチル型等の修飾ヌクレオチドであってもよい。アンチセンス核酸の設計に重要な他の要素として、水溶性および細胞膜透過性を高めること等があげられるが、これらはリポソームやマイクロスフェアを使用するなどの剤形の工夫によっても克服できる。アンチセンス核酸の長さは、転写産物と特異的にハイブリダイズし得る限り特に制限はなく、短いもので約15個のヌクレオチド程度、長いもので転写産物の全配列に相補的な配列を含むような配列であってもよい。合成の容易さや抗原性の問題等から、例えば約15個以上のヌクレオチド、好ましくは約15個~約100個のヌクレオチド、より好ましくは約18個~約50個のヌクレオチドからなるオリゴヌクレオチドが例示される。さらに、アンチセンス核酸は、転写産物とハイブリダイズして翻訳を阻害するだけでなく、二本鎖DNAと結合して三重鎖(トリプレックス)を形成し、mRNAへの転写を阻害し得るものであってもよい。
RNAi誘導性核酸とは、細胞内に導入されることにより、RNA干渉(RNAi)効果を誘導し得るポリヌクレオチドをいい、好ましくはRNAである。RNAi効果とは、mRNAと同一の核酸配列またはその部分配列を含む2本鎖構造のRNAが、当該mRNAの発現を抑制する現象をいう。RNAi効果を得るには、例えば、少なくとも19の連続する標的mRNAと同一の核酸配列(またはその部分配列)を有する2本鎖構造のRNAを用いることが好ましい。2本鎖構造は、異なるストランドで構成されていてもよいし、一つのRNAのステムループ構造によって与えられる2本鎖であってもよい。RNAi誘導性核酸としては、例えばsiRNA、miRNAなどがあげられるが、siRNAが好ましい。siRNAは、RNAiを誘導できる限り特に制限されないが、例えば19~27塩基長、好ましくは21~25塩基長である。
アプタマーとは、所定の標的分子に対する結合活性(または阻害活性)を有するポリヌクレオチドをいう。アプタマーは、RNA、DNA、修飾ヌクレオチドまたはそれらの混合物である。アプタマーはまた、直鎖状または環状の形態であってもよい。アプタマーの長さは特に限定されず、通常、約16~約200個のヌクレオチドであるが、例えば約100個のヌクレオチド以下であり、好ましくは約50個のヌクレオチド以下であり、より好ましくは約40個のヌクレオチド以下である。また、アプタマーの長さは、例えば約18個、約20個、約25個または約30個ヌクレオチド以上であってもよい。アプタマーは、結合性、安定性、薬物送達性等を高めるため、各ヌクレオチドの糖残基(例、リボース)が修飾されたものであってもよい。糖残基において修飾される部位としては、例えば、糖残基の2’位、3’位および/または4’位の酸素原子を他の原子に置き換えたものなどがあげられる。修飾の種類としては、例えば、フルオロ化、O-アルキル化、O-アリル化、S-アルキル化、S-アリル化およびアミノ化があげられる(例、Sproat et al., (1991) Nucl. Acid. Res. 19, 733-738;Cotton et al., (1991) Nucl. Acid. Res. 19, 2629-2635参照)。アプタマーはまた、プリン、ピリミジンが改変されたものであってもよい。このような改変としては、例えば、5位ピリミジン改変、8位プリン改変、環外アミンでの改変、4-チオウリジンでの置換、5-ブロモまたは5-ヨード-ウラシルでの置換があげられる。また、ヌクレアーゼおよび加水分解に対して耐性であるように、本発明のアプタマーに含まれるリン酸基が改変されていてもよい。例えば、リン酸基が、チオエート、ジチオエートまたはアミデートで置換されていてもよい。アプタマーは、既報(例えば、Ellington et al., (1990) Nature, 346, 818-822;Tuerk et al., (1990) Science, 249, 505-510)に従って作製できる。
抗体は、ポリクローナル抗体(抗血清)、モノクローナル抗体のいずれであってもよく、周知の免疫学的手法により作製することができる。モノクローナル抗体は、IgG、IgM、IgA、IgDあるいはIgE等のいずれのアイソタイプであってもよいが、好ましくはIgGまたはIgMである。
また、本発明は、急性骨髄性白血病患者に対する自家移植または同種移植のための造血細胞を含む試料の製造方法を提供する。本発明の製造方法は、
a)当該患者またはドナーから造血細胞を含む試料を採取する工程、
b)採取した試料と、少なくとも1種の白血病幹細胞マーカー遺伝子の翻訳産物を認識する物質とを接触させる工程、ならびに
c)前記物質が結合した細胞を選別し、白血病幹細胞がパージングされた試料を得る工程を含む。すなわち、本発明は、自家移植または同種移植用の造血細胞を含む試料から白血病幹細胞を実質的に除去し、再発の懸念のない移植用試料を提供することができる。
ADFP、ALOX5AP、CACNB4、CD33、CD3D、CD93、CD97、CLEC12A、DOK2、FCER1G、FCGR2A、GPR34、GPR84、HCST、HOMER3、IL2RA、IL2RG、IL3RA、ITGB2、LY86、P2RY5、PTH2R、SUCNR1、TNFRSF4、TYROBPおよびVNN1から選ばれる少なくとも1種の細胞表面マーカー遺伝子を標的とすることが好ましい。
試料は、通常、骨髄穿刺または末梢血採取により行われる。骨髄穿刺は、例えば、S. E. Haynesworth et al. Bone, 13, 81 (1992)に記載された方法等に基づき胸骨または腸骨から骨髄穿刺を行う。具体的には、骨髄穿刺を行う場所の皮膚面を消毒し、局所麻酔を行う。特に骨膜下を充分に麻酔する。骨髄穿刺針の内筒を抜き、5000単位のヘパリンを入れた10mL注射器を装着して必要量の骨髄液を速やかに吸引する。平均的には10 mL~20 mLの骨髄液を吸引する。骨髄穿刺針を取り外し、10分間程圧迫止血する。取得した骨髄液を1,000×gの遠心分離により骨髄細胞を回収した後、該骨髄細胞をPBS(Phosphate Buffered Saline)で洗浄する。洗浄工程を数回繰り返した後、造血細胞を含む試料を得ることができる。
本工程で用いるマーカー遺伝子の翻訳産物を認識する物質は、前述した抗体があげられ、特に、ADFP、ALOX5AP、CACNB4、CD33、CD3D、CD93、CD97、CLEC12A、DOK2、FCER1G、FCGR2A、GPR34、GPR84、HCST、HOMER3、IL2RA、IL2RG、IL3RA、ITGB2、LY86、P2RY5、PTH2R、SUCNR1、TNFRSF4、TYROBPおよびVNN1から選ばれる少なくとも1種の細胞表面マーカーに対する抗体が好ましい。抗体は蛍光標識されていることが好ましく、標識に用いる蛍光色素はフローサイトメトリーに一般的に用いられている蛍光物質であることが好ましい。蛍光色素の具体例としては、FITC(フルオレッセインイソチオシアネート)、PE(フィコエリトリン)、PerCP(ペリジニンクロロフィルタンパク質)、PerCP-Cy5.5、PE-Cy5、PE-Cy7、PE-TR(PE-テキサスレッド)、APC(アロフィコシアニン)およびAPC-Cy7などがあげられる。接触は、前記細胞表面マーカー(抗原)と抗体との結合が達成される条件であれば特に限定されない。
本工程において、細胞の選別は、フローサイトメトリーと組み合わせることで容易に達成することができる。蛍光標識した抗体と接触させた試料をフローサイトメーターにセットし、抗体と結合した細胞を選別し、当該試料から白血病幹細胞を分離することができる。
すべての実験は、理化学研究所免疫・アレルギー科学総合研究センターのInstitutional Review Board for Human Researchからの承認により実施した。AML患者由来の白血病細胞は、書面によるインフォームドコンセントにより収集した。健常ドナー由来のCB(臍帯血)は、書面によるインフォームドコンセントとともにTokyo Cord Blood Bankにより収集した。健常ドナー由来のBMMNC(骨髄単核球細胞)は、Cambrex(Walkerville, MD)から入手した。AML患者由来のBMMNCおよびCBMNC(臍帯血単核球細胞)は、密度勾配遠心分離を使用して単離した。
蛍光活性化セルソーティング(FACS)のため、AML患者のBMMNC細胞を、蛍光色素結合マウス抗hCD3、抗hCD4、抗hCD8、抗hCD34および抗hCD38モノクローナル抗体(BD Biosciences,San Jose, CA)で標識し、レシピエントBMMNC細胞を、マウス抗hCD45、抗hCD34および抗hCD38モノクローナル抗体(BD Biosciences)で標識し、FACSAria (BD Biosciences)を用いて細胞をソーティングした。FSC/SSC高さおよびFSC/SSC幅の分析によって、ダブレットを排除した。ソーティング後のhCD34+hCD38-およびhCD34+細胞の純度は、98%よりも高かった。フローサイトメトリー解析のため、AML患者のBMMNC、レシピエント末梢血またはレシピエントBMを、上述した蛍光色素結合マウス抗hCD3、抗hCD4、抗hCD8、抗hCD34および抗hCD38モノクローナル抗体またはマウス抗hCD45、抗hCD34および抗hCD38モノクローナル抗体で標識した。
全RNAを、TRIzol試薬(Invitrogen)を用いて抽出し、Agilent Bioanalyzerを用いて当該RNAの完全性を評価した。Human Genome U133 plus 2.0ジーンチップ(Affymetrix)に対して、Two-Cycle Target Labelingキット(Affymetrix)を用いてビオチン化cRNAを合成した。Human Gene 1.0STジーンチップ(Affymetrix)に対して、第1ラウンドのcDNA合成およびcRNA増幅を、MessageAmp Premier RNA Amplificationキット(Applied Biosystems)を用いて行い、続く第2ラウンドのcDNA合成、ビオチン化および断片化を、WT cDNA合成およびTerminal Labelingキット(Affymetrix)を用いて行った。ハイブリダイゼーション、洗浄、染色およびスキャニングを、製造業者の指示書に従って行った。まず、各プラットフォームについて、Bioconductorパッケージ(http://www.bioconductor.org/)を用いて、マイクロアレイデータを別々に解析した。マイクロアレイプラットフォーム上のプローブセットのシグナル強度を、GC-RMAプログラム(Zhijin et al., J. Am. Stat. Assoc., 99, 909-917, 2004)を用いて正規化した。各プラットフォームに対して、正規化したデータをRankProdプログラム(Hong et al., Bioinformatics, 22, 2825-2827, 2006)により解析し、カットオフp値0.01かつ擬陽性推定0.05%として、LSCとHSCとの間で示差的に発現した遺伝子を選択した。HSCに比べてLSCで有意に高いレベルの発現が両方のマイクロアレイプラットフォームで共通して観察された場合、当該遺伝子を顕著なLSCマーカーの遺伝子候補として選択した(図5、表1)。さらに、Human Gene 1.0STジーンチップにおいて高率にヒットした遺伝子IL2RAも、タンパク質レベルでの解析結果がよく、後述する抗癌剤抵抗性の幹細胞で発現しているという観点から、マーカー遺伝子候補として選択した(表1)。候補の局在および生物学的機能は、Ingenuity Pathway Analysisデータベース(Ingenuity Systems)およびジーンオントロジーアノテーションデータベース(http://www.ebi.ac.uk/GOA/)の情報に基づいてアノテーションした。
HSCおよびLSCから10ngの全RNAを、WT-Ovation RNA増幅システム(Nugen)を用いるcDNA増幅に供した。cDNA産物をTEで1:7.5に希釈し、25μlのqPCR反応あたり1μlの希釈産物を使用した。二重標識した蛍光プローブおよび遺伝子特異的プライマー(Sigma-Aldrich)の配列を、表3に記載した。PCR反応は、LightCycler 480(Roche Applied Science)を使用して、Platinum Quantitative PCR SuperMix-UDG(Invitrogen)で行った。各転写物の存在量は、標準曲線法(Methods, 25, 386-401, 2001)により計算した。Kaleida Graphソフトウェアパッケージ中のKruskal-Wallis、Wilcoxon-Mann-Whitney、Student’s t-検定のいずれかがP<0.05を示した場合、LSCとHSCとの間で発現レベルが有意に異なるとみなした。
NOD.Cg-PrkdcscidIl2rgtmlWjl/Sz(NOD/SCID/IL2rgnull)マウスは、Il2rg遺伝子座の完全ヌル変異をNOD.Cg-Prkdcscid(NOD/SCID)系統と戻し交雑することによって、The Jackson Laboratory(Bar Harbor, ME)で開発された(Shultz, L.D. et al. Multiple defects in innate and adaptive immunologic function in NOD/LtSz-scid mice. J Immunol 154, 180-191 (1995))。マウスを、理研およびThe Jackson Laboratoryの動物施設で、各施設でInstitutional Animal Committeesによって確立されたガイドラインに従って、照射した食物および酸性化した水を用いて飼育し、規定された細菌叢のもとで維持した。
新生仔(誕生後2日以内) NOD/SCID/IL2rgnullマウスに、137Cs源照射器を使用して、150cGyの全身照射を与え、その後2時間以内にAML細胞の静脈内注射を行なった。レシピエントは、3~4週間毎に後眼窩から採血し、末梢血ヒトAML移植キメリズムを調べた。
原発AML移植レシピエントの大腿骨から、パラホルムアルデヒド固定し脱灰したパラフィン包埋切片を調製した。標識に使用した一次抗体は、マウス抗ヒトCD45モノクローナル抗体(DAKO, Denmark)およびウサギ抗CD32モノクローナル抗体(Abcam, UK)であった。Zeiss LSM ExciterおよびLSM 710 (Carl Zeiss)を用いて、レーザースキャニング共焦点イメージングを得た。
原発AMLを移植し、抗癌剤処置したレシピエントの大腿骨から、パラホルムアルデヒド固定し脱灰したパラフィン包埋切片を調製し、DAPI(核染色:青);各マーカー(FCGR2A, AK5, DOK2, LRG1, BIK, IL2RA, WT1, SUCNR1:赤);静止細胞マーカー(緑:CD34(FCGR2A, AK5, DOK2, LRG1, BIK)またはKi67(IL2RA, WT1, SUCNR1)に対する抗体で標識した。Zeiss LSM ExciterおよびLSM 710 (Carl Zeiss)を用いて、レーザースキャニング共焦点イメージングを得た(図7)。

尚、WT1は、白血病をはじめ、多くの腫瘍にて発現が確認されている。しかし、この分子が再発や抗がん剤抵抗性を示す幹細胞レベルに発現しているかどうかについては、知られていなかった。本発明者らは、細胞周期が静止した、ニッチに存在する白血病幹細胞に発現することを見出したことから、これまでの化学療法や放射線治療では死滅させることができなかった白血病幹細胞を殺すための標的分子として意義があることを示している。
