Abstract
Description
本願は2013年6月3日付けで出願された米国仮出願第61/830,178号(その開示が引用することにより本明細書の一部をなす)の米国特許法第119条(e)項に基づく利益を主張するものである。
WASp及びWIPの発現における分子変化を、ヒト癌性細胞でのWASp及びWIPの発現を正常末梢血リンパ球(PBL)に対して比較することによって検査した。悪性細胞株は造血器悪性疾患に由来するものとした。PBLを健常ドナーの全血からフィコール勾配を用いて単離した後、フィトヘマグルチニン(PHA)及びインターロイキン−2を用いてリンパ球を増加させた。トリス含有溶解緩衝液を用いて細胞を溶解した。タンパク質溶解物をドデシル硫酸ナトリウム−ポリアクリルアミドゲル電気泳動(SDS−PAGE)で分離し、ニトロセルロース膜に転写し、適切な一次抗体(マウス抗WASp又はウサギ抗WIP又はマウス抗GAPDH)を用いて免疫ブロットした。免疫反応性タンパク質を抗マウス又は抗ウサギホースラディッシュペルオキシダーゼ結合二次抗体を用いて検出した後、増強化学発光による検出を行った。ALL、CLL及びNHLを含む様々な悪性造血細胞に由来する細胞抽出物で2倍〜6倍のWASp及びWIPの過剰発現が検出された。特に、両タンパク質の過剰発現は強く相関する。これらの結果から、WASp及びWIP発現が増大したリンパ球の標的化並びにWASp及びWIP過剰発現の妨害が造血器悪性疾患の有用な療法であり得ることが示される。
細胞浸潤に対するWASpの影響をゼラチナーゼベースのアッセイを用いて試験した。WASpをコードするプラスミドをトランスフェクトしたリンパ球は、WASp発現レベルが倍増しなかった対照プラスミドをトランスフェクトした細胞とは対照的に2倍のレベルのWASpを発現し、ゼラチナーゼ活性の増大を示した。ゼラチナーゼ活性は、典型的には細胞浸潤を伴うECM分解を表す。ECM分解はファロイジン染色によって示されるようにF−アクチンの蓄積と共局在化していた。これらの結果から、WASp過剰発現が細胞浸潤能の増大に関連することが示される。悪性細胞におけるWASp発現を減少させることにより細胞の浸潤能力を減少させ、悪性転移を低減することができる。
活性化黄色蛍光タンパク質(YFP)WASp発現細胞のリアルタイムイメージングを行い、野性型WASp発現細胞とN末端が切断された蓄積非分解性突然変異型WASpを発現する細胞とを比較した。細胞を適切なレーザー、フィルター及び検出器を備える共焦点顕微鏡を用いてモニタリングした。突然変異型WASpを発現する細胞は正常に伝播せず、代わりに連続的にローリングし(rolled)、移動した。これらの細胞は平膜構造(膜状仮足)を形成せず、代わりに移動性癌性細胞の特徴であるスパイク状の膜突出(糸状仮足)を生じた。これらの結果から、細胞中のWASp蓄積が該細胞における癌性細胞構造の存在と関連し得ることが更に示される。HTLを用いてWASp発現を制御することで、悪性特徴を低減することができる。
実施例1Cに記載のリンパ球を使用し、細胞内カルシウム濃度及び転写因子である活性化T細胞核因子(NFAT)の活性(それぞれリンパ球の活性化及び増殖の指標である)を測定することによってリンパ球活性化に対するWASp蓄積の影響を評価した。カルシウムレベルは、カルシウム感受性Fluo−3フルオロフォアを使用する分光蛍光分析を用い、NFATルシフェラーゼレポータープラスミドとの共トランスフェクションによって決定した。突然変異型YFP−WASpが発現され、蓄積した細胞において細胞内カルシウム濃度及びNFATレベルの両方の顕著な増大が示された。この結果から、リンパ球におけるWASp蓄積がリンパ球の活性化及び増殖を増大し得ることが示される。
先の実施例に示されるように、WASpは悪性細胞において過剰発現する。siRNAを用いたWASp発現の遺伝子サイレンシングを試験した。WASpを、市販のsiRNAオリゴヌクレオチドを用いてサイレンシングした。各々その対応する配列との二本鎖siRNAの二重鎖の形態である以下のオリゴヌクレオチドの混合物500ピコモル量を、1×107個の細胞に導入した:5’−GCCGAGACCUCUAAACUUA−3’(配列番号4)、5’−UGACUGAGUGGCUGAGUUA−3’(配列番号1)、5’−GAAUGGAUUUGACGUGAAC−3’(配列番号3)及び5’−GACCUAGCCCAGCUGAUAA−3’(配列番号2)。これらの実験はT細胞型白血病細胞において行った。非特異的(N.S)siRNA処理細胞と比較して、トランスフェクションの48時間後に約90%のサイレンシング効率が達成された。
HTL又はWTLとして使用される抗体をコーティングしたリポソームは、以下のように作製することができる。最初の工程では、6:2:2(又は代替的には検出のためにローダミンフルオロフォアで標識した0.1%DPPEを添加して6:2:1.9)のモル比のホスファチジルコリン(PC)、コレステロール(Chol)及び1,2−ジパルミトイル−sn−グリセロ−3−ホスホエタノールアミン(DPPE)から構成される多層ベシクル(MLV)を調製する。脂質混合物を、60セルシウス度(℃)で35分(minutes (min))〜40分間撹拌することによってクロロホルムに2ミリグラム毎ミリリットル(mg/ml)の最終濃度まで溶解する。その後、65℃で30分間の真空回転蒸発を行う。脂質混合物を真空デシケーターで更に一晩乾燥させる。得られる乾燥脂質薄膜をpH7.4の希釈リン酸緩衝食塩水(PBS)で水和させ、十分にボルテックスした後、オービタルシェーカーを用いて200回転毎分(rpm)、37℃で2時間混合し、MLVを生成する。
化合物はChemBridge Corporation(San Diego,CA,USA)から入手した。得られる化合物のうち14個が、WASpに結合するその能力によってWASp発現を変調する潜在的作用物質とみなされた。この14個の化合物を293T細胞において以下の手順を用いて試験した。
多数のsiRNA二重鎖を実施例1Eと同様に細胞中で試験した。以下の二本鎖siRNA配列を使用した:配列番号1及びその相補配列;配列番号2及びその相補配列;配列番号3及びその相補配列;配列番号1及びその相補配列(1〜4と表す)。500ピコモルの各二本鎖siRNAを使用した。加えて、ナンセンスsiRNA配列(「N.S.siRNA」と表す)を対照として使用した。対照N.S.siRNAは表5中の各々のsiRNA分子の125個の二重鎖から作製した。
本発明の実施形態によると、WIP様ペプチドを作製することができる。WIP様ペプチドは、天然のWIPペプチドの一部分と同様であるが潜在的修飾を有するペプチドである。本発明の一実施形態によると、WIP様ペプチドは天然のWIPの対応する部分と90%の類似性を有する。本発明の一実施形態によると、WIP様ペプチドは、WASpのユビキチン化部位であることが観察されているリシン残基76及び81でWASpに結合する。理論に束縛されるものではないが、WIP様ペプチドはWASpのこれらのリシン残基に結合し、それによりWASpをユビキチン化及びその後の分解から保護することが示唆される。
WASノックアウトマウスを用いる。野生型(WT)同腹子を対照として用いる。マウスを病原体除去条件下で飼育する。WASp分解部位でWASpに結合し、ユビキチン化又はカルパイン媒介タンパク質分解によるWASpの分解を防止するペプチドを含むリポソームの懸濁液(200μl)を超音波洗浄器(bath sonicator)内で5分間超音波処理し、即座に尾静脈から静脈注射する。体重及び臨床症状を毎日モニタリングする。マウスを9日目に屠殺し、脾臓を摘出する。リンパ球及び巨核球細胞系列を精製し、WASp発現レベルについて分析する。
5週齢〜6週齢の雌性NOD/SCID(NOD/LtSz−scid/scid)マウスを購入し、病原体除去環境下で飼育する。接種日に、マウスに250センチグレイ(centigeiger)(cGy)の全身照射を平行対向4MV x線によって325cGy/分の線量率で行う。接種の直前にマウスを赤外線ランプで温めた後、尾静脈注射によって2.5〜10×106個の白血病細胞を100mL PBSの最大容量で接種する。尾静脈から採取したおよそ50mLの末梢血を抗CD45(白血球共通抗原、Ly−5)抗体、FITCコンジュゲート抗ネズミ及びPEコンジュゲート抗ヒトCD45で染色することによって、マウスを14日毎に白血病生着についてモニタリングする。赤血球を塩化アンモニウムで溶解した後、サンプルをフローサイトメトリーによって分析する。ヒトに対するネズミCD45細胞の割合を算出する。このパラメーターは全白血病負荷を正確に反映することが示されている。この方法ではネズミ末梢血中1%のヒトCD45細胞が検出されるはずである。
