PAI-1の存在が造血再生に対して抑制的に働くことを示すため、PAI-1遺伝子欠損マウス(PAI-1-KOマウス)(B6.129S2-Serpine1tm1Mlg/J:ジャクソン研究所(Bar Harbor, ME))、及び比較対照として野生型マウスをレシピエントとして、造血幹細胞の移植実験を行った。なお、実験はPAI-1-KOマウス及び野生型マウスのそれぞれ9匹に対して行った(n=9)。
重度免疫不全マウス(レシピエント)に放射線(2Gy)を照射し、2日後に、ヒト臍帯血から分離したヒトCD34+細胞を移植した。移植と同時に被験化合物として、化合物aを経口投与し(投与量100mg/kg)、以後5日間、計6回の投与を行った(図2A参照)。最終投与から2日目(細胞移植から7日目)に骨髄細胞を回収し、ヒト造血細胞の存在比率をフローサイトメーターで計測するとともに、血漿中のcKitL濃度(pg/mL)及びVEGF濃度(pg/mL)を測定した。なお、コントロール試験として、NOGマウスに、化合物aに代えて、化合物aの溶解に使用したPBSを同様に経口投与し、上記試験を行った(対照群)。
図3Aに、放射照射をしない骨髄組織をプラスミノーゲン/プラスミン染色した結果を、図3Bに、放射線照射(9Gy)から2日経過した後の骨髄組織をプラスミノーゲン/プラスミン染色した結果を、それぞれ示す。図3Bに示す白い矢印は、骨髄の微小環境において、プラスミノーゲン/プラスミンがより高く発現していることを示している。図3Cは、放射線照射(10Gy)から2日経過した後のHESS5骨髄間質細胞培養培地中のプラスミノーゲンの総量(ng/mL)を測定し、放射線を照射しない(0Gy)HESS5骨髄間質細胞培養培地中のプラスミノーゲンの総量(ng/mL)と比較した結果を示す(*p<0.05)。
図4Aに記載する手順に従って、化合物aの造血回復に及ぼす効果を評価した。
骨髄移植日から、2日目、7日目及び21日目に血液を採取し、血漿中のプラスミノーゲン量(ng/mL)、活性型組織プラスミノーゲン活性化因子(tPA)、cKitリガンド、及びMMP-9(Matrix metalloprotein-9)の総量、並びに末梢血中の白血球数(×10E3 cell/μL)を測定するとともに(以上、各群n=6)、骨髄移植後のマウスの生存率を経時的に追跡した(各群n=15)。
骨髄移植から7日目のマウス(投与群、対照群)から採取した骨髄細胞について、Lin-SLAM細胞の存在をフローサイトメーターで計測した(図5A参照)。なお、各試験は、各々別個に行った(各群n=6)。
骨髄移植から7日目のマウス(投与群、対照群)から採取した骨髄細胞について、プラスミノーゲン(Plg)のmRNA発現量、tPAのmRNA発現量、及びPAI-1のmRNA発現量を測定した。
骨髄移植から13週間目のマウス(投与群及び対照群)から骨髄を回収し、全骨髄の総数(図7A)、全骨髄中のLSK-CD34陰性細胞の割合(%)(図7B)、全骨髄中のCD34(-)KSL細胞の総数(図7C)、全骨髄中のLin-SLAM細胞の割合(%)(図7D)、全骨髄中のLin-SLAM細胞の総数(図7E)、全骨髄中の骨髄分化細胞(CD45.1/Mac1/Gr1細胞)の割合(%)(図7F)、全骨髄中の骨髄分化細胞(CD45.1/Mac1/Gr1細胞)の総数(図7G)、全骨髄中のB細胞リンパ性分化細胞(CD45.1/B220細胞)の割合(%)(図7H)、及び全骨髄中のB細胞リンパ性分化細胞(CD45.1/B220細胞)の総数(図7I)を測定した。結果を、上記に記載する各図に示す。
被験化合物として、上記化合物aに加えて、化合物b及びcをそれぞれ用いて、実験例4(1)及び(4)と同様の実験を行った。
(1)化合物aのIn vivoラットを用いた単回投与毒性試験及び2週間反復毒性試験
(i) 化合物aのラットを用いた単回投与毒性試験
化合物aの単回投与毒性は、Sprague-Dawley系ラット(Crl:CD(SD))の雄で162~177g、雌で120~136gを日本チャールス・リバーから入手し、これを用いて評価した。これらのラットに化合物aを500、1000及び2000mg/kgの割合で強制経口投与した。投与後、これらのラットの動態を2週間モニターしし、化合物aの毒性を評価した。雌雄いずれのラットにおいても異常は認められず、また、雌雄いずれのラットにも化合物aの投与による明らかな体重変化は認められず、順調な体重増加を示した。さらに剖検を行った結果、いずれの個体にも特に異常はみられず、これらの結果を総合して、化合物aの単回経口投与時の毒性は低いと推定された。
化合物aの反復投与毒性は、Sprague-Dawley系ラット(Crl:CD(SD))の雄で210~238g、雌で145~166gを日本チャールス・リバーから入手し、これを用いて評価した。化合物aを0(0.5w/v%カルメロースナトリウム溶液)、200、600及び2000mg/kg/日の投与量で各群雌雄各5匹のSprague-Dawley系ラット(Crl:CD(SD)、投与開始時6週齢)に2週間反復経口投与を行い、毒性試験を実施した。
化合物a(50mg/kg)を、180-200gの雄のWisterラットに強制経口投与した。投与前(0h)、並びに投与後1、2、6および24時間目に採血し、各血漿中に含まれる化合物aの濃度を逆相HPLCにより分析し、最高薬物濃度時間(Tmax)、最高薬物濃度(Cmax)、および半減期(T1/2)を求めた。結果を表5に示す。
化合物aに、線溶系を活性化させ、造血幹細胞の自己複製を促進させる効果があることを証明するため、実験例4と同様の実験を行った
(1)実験方法
図10Aに記載する手順に従って、化合物aの造血回復に及ぼす効果を評価した。
骨髄移植日から、2日目及び7日目に血液を採取し、血漿中の活性型PAI-1量(ng/mL)、活性型組織プラスミノーゲン活性化因子(active tPA)、プラスミン量(ng/mL)、cKitリガンド、及びMMP-9(Matrix metalloprotein-9)の総量を測定した。評価に供したマウス数は、各群n=12である。
つぎに、骨髄再生に化合物aが促進的に作用することを立証するため、骨髄除去後の生存率における化合物aの効果を評価した。放射線照射による骨髄除去例として、実施例7(1)に示した実験例において、15匹のマウスについて移植後28日目までの生存率を、6匹のマウスについて末梢血の白血球(WBC)数及び血小板(PLT)数を観察した。
化合物aによる線溶系の活性化が、tPAを介して、骨髄移植後の骨髄における造血幹細胞増殖を誘導することを立証するため、骨髄移植後の造血幹細胞の出現率及び絶対数を測定した。
実験例7(1)の方法にしたがって、骨髄移植を行った後、実施例7と同様にtPA投与または化合物a投与を行った。対照群には生理食塩水を投与した。各群それぞれ12匹について、骨髄移植から1週間後及び3週間後に、骨髄単核細胞(BM MNC)数、Lin-SLAM細胞の出現率及びその絶対数、LSK-CD34陰性細胞の出現率及び絶対数を測定した。
次に実験例8(1)で示された、化合物aによる造血幹細胞増加促進作用が、PAI-1を阻害したことによる、tPAの活性化を介して行われていることを立証するため、tPA遺伝子欠損マウス(tPA-KO-マウス)をレシピエントとして、実験例7と同様の骨髄移植実験を行い、化合物aの造血幹細胞増加促進作用が認められなくなるか否かを検討した。
次に実験例8で示された化合物aの造血幹細胞数の増加の促進が、造血幹細胞自身を増加させる作用であることを確認するため、細胞増殖マーカーを使って骨髄移植後に生理食塩水または被験化合物を投与したマウスの骨髄単核細胞中およびLSK細胞中の分裂細胞の割合を測定した。
実験例7(1)に準じて、骨髄移植を行い移植後、生理食塩水(対照群)、tPA(tPA投与群)または化合物a(化合物a投与群)の投与を行った。
次に、化合物aによって造血幹細胞の増殖が促進されていることを確認するため、LSK分画の細胞内でのKi-67陽性細胞数を検討した。
さらに、S期に移行している細胞をより正確に検出するため、対照群、tPA群、化合物a投与群それぞれについて、骨髄移植の1週間後に骨髄を採取する3時間前に、5-bromo-2-deoxyuridine (BrdU)-FITC (BD Pharmingen)を投与した。使用したマウスは各群6匹である。
放射線照射後の骨髄環境は劣悪であり、造血幹細胞はその環境下で自己複製と骨髄の再生を行わなければならない。このような条件は、造血幹細胞に大きなストレスを負荷することとなるため、自己複製能を有する造血幹細胞であっても、その活性は低下し、アポトーシスに陥る細胞も少なくない。
骨髄移植後のように、造血幹細胞の増殖が増大されると、早期の骨髄幹細胞の枯渇が起こり、長期的な造血系の恒常性が維持できなくなることが知られている。
骨髄移植から15週間経過した対照群、tPA群、化合物a投与群のそれぞれ12匹のマウスについて、骨髄単核細胞(BM MNC)数、Lin-SLAM細胞の出現率及びその絶対数、LSK-CD34陰性細胞の出現率及び絶対数を測定した。
次にPAI-1阻害剤が長期間自己複製能力を維持する長期(Long-term)造血幹細胞に対してどのような作用を示すかを検討した。
長期造血幹細胞の頻度を比較するため、最初の移植されるドナー骨髄を希釈して移植し、限界希釈法によってPAI-1阻害の効果を評価した。
実験例4及び5で示したように、化合物a、化合物b及び化合物cといったPAI-1阻害剤は造血幹細胞の頻度を高め、造血幹細胞の自己複製活性を増強する作用すなわち細胞周期をG0期からG1期に移行させる作用を有している。
MIGR1ベクターにp210(BCR-ABL)遺伝子を挿入し、さらにこの遺伝子の下流にレポーター遺伝子としてGFP cDNAを組み込んだ(以下、このベクターを「p210-GFP」と称する)。p210-GFPをC3H/HeJマウス細胞株32D細胞に感染させ、慢性骨髄性白血病(以下、「CML」と称する)細胞を作製した。斯くして得られたCML細胞(32Dp210(BCR-ABL)-GFP細胞、以下「32Dp210-GFP細胞」ともいう)2.5×105個を、C3H/HeJマウスの眼窩静脈叢より静注した。移植後7~10日目に末梢血中のGFP細胞の存在比率を解析して、3%を超えた個体を慢性骨髄性白血病モデルマウスとして以下の実験に使用したす。
上記の方法で作製した慢性骨髄性白血病モデルマウス15匹を下記に示す3群に分けて(各群n=15)、図15Aに示すプロトコールに従って被験薬を投与した。
Group 2:イマチニブ群(イマチニブ[150mg/kg/day]を強制経口投与)
Group 3:「イマチニブ+化合物a」群
(イマチニブ[150mg/kg/day]と化合物a[100mg/kg/day]を強制経口投与)
CML細胞を静注した日(Day 0)から10日後(Day 10)から、上記各群にそれぞれの被験薬の投与を開始した。プラセボ群及びイマチニブ群は、Day 10からDay 16まで、毎日1回計7回の被験薬投与を行った。「イマチニブ+化合物a」群については、イマチニブの投与を、Day 10からDay 16まで、毎日1回計7回行い、化合物aの投与を、Day 10からDay 14まで毎日1回計5回行った。
(3-1)生存率
各群のマウスの生存率を図15Bに示す。これに示すように、プラセボ群(○)は、実験した5匹すべてがDay 10からDay 17までに死亡した。イマチニブ群(▲)は、プラセボ群よりは長生きしたものの、Day 40までにすべてのマウスが死亡した。これに対して、「イマチニブ+化合物a」群(■)はDay 30からDay 50までの間に6匹のマウスが死亡したものの、Day 50での生存率は60%であった。各群の生存期間中央値は、プラセボ群14日、イマチニブ群27日、「イマチニブ+化合物a」群40日であった。イマチニブ群に対する「イマチニブ+化合物a」群の生存率の有意差はp<0.0001であり、抗がん剤であるイマチニブとPAI-1阻害剤である化合物aとを併用することにより、有意に生存期間が長くなることが示された(予後がよい)。
(3-2)骨髄及び脾臓のCML細胞数
上述したように、32Dp210-GFPはレポーター遺伝子としてGFPを有しているため、それを導入したCML細胞(32Dp210-GFP細胞)はGFPが陽性となる。そこでFACS (FACS (BD Biosciences: FACSCalibur)を使って、骨髄及び脾臓の単核細胞中におけるCML細胞(32Dp210-GFP細胞)の出現頻度をイマチニブ群と「イマチニブ+化合物a」群とで測定して比較した。
実験例11と同様の実験を、PAI-1阻害剤として化合物cを用いて行った。
実験例11と同様にして作製した慢性骨髄性白血病モデルマウスを下記の3群(各群:n=10)に分けて、各群に図15Aに示すプロトコールに準じて対応する被験薬を投与した。
Group 2:イマチニブ群(イマチニブ[150mg/kg/day]を強制経口投与)
Group 3:「イマチニブ+化合物c」群
(イマチニブ[150mg/kg/day]と化合物c[10mg/kg/day]を強制経口投与)
CML細胞(32Dp210-GFP細胞)を静注した日(Day 0)から8日後(Day 8)から、それぞれの薬剤の投与を開始した。プラセボ群及びイマチニブ群は、Day 8からDay 14まで、毎日1回計7回の被験薬投与を行った。「イマチニブ+化合物c」群については、イマチニブの投与をDay 8からDay 14まで毎日1回計7回行い、化合物cの投与をDay 8からDay 14まで毎日1回計7回行った。
結果を図16に示す。図に示すようにプラセボ群(○)は、実験した10匹すべてがDay 10からDay 20までに死亡した。イマチニブ群(▲)は、プラセボ群よりは長生きしたもののDay 35までにすべてのマウスが死亡した。これに対して、「イマチニブ+化合物c」群(■)はDay 25からDay 40までの間に3匹のマウスが死亡したものの、Day 40での生存率は70%であった。各群の生存期間中央値は、プラセボ群15.5日、イマチニブ群23.5日、「イマチニブ+化合物c」群40日であり、抗がん剤であるイマチニブと、PAI-1阻害剤である化合物cとを併用することにより、有意に生存期間が長くなることが示された(予後がよい)。これは、実験例11で示した化合物aと同様に、抗がん剤(イマチニブ)をPAI-1阻害剤である化合物cと併用することにより、イマチニブを単独で使用するよりもより強い腫瘍細胞死滅作用が得られることを示している。
上記実験例12で示したPAI-1阻害剤である化合物cの作用が、G-CSFを介した作用であるか否かを確認するため、G-CSFの中和抗体が、化合物cの造血再生促進作用、腫瘍細胞死滅作用に影響を与えるかを、骨髄移植動物を使用して評価した。
実験例4と同様にして骨髄移植マウスを作成し、化合物c、G-CSF及びG-CSF中和抗体の効果を検討した。具体的には、骨髄移植マウスを下記に従って5群に分けて(各群:n=5)、それぞれに対応する被験薬を経口投与した。
Group 2:化合物c群(化合物c[10mg/kg/day]強制経口投与)(TM群という)
Group 3:G-CSF群(G-CSF[150μg/kg/day]強制経口投与)(G群という)
Group 4:vehicle+anti G-CSF群(生理食塩水+G-CSF中和抗体[500μg/kg/day]強制投与)(v+Ab群という)
Group 5:化合物c+anti G-CSF群(化合物c[500μg/kg/day]+ G-CSF中和抗体[500μg/kg/day]強制投与)(TM+Ab群という)
ベヒクル群には、骨髄移植と同時に生理食塩水(vehicle)の強制経口投与を開始し、5日間にわたって投与した。化合物c群は、骨髄移植と同時に10mg/kg/dayの化合物cの強制経口投与を開始し5日間にわたって投与した。G-CSF群は、骨髄移植と同時にG-CSF(150μg/kg/day)の皮下投与を開始し、5日間にわたって投与した。vehicle+anti G-CSF群は、生理食塩水の強制経口投与とG-CSF中和抗体(R&D社)(500μg/kg/day)の皮下投与を、骨髄移植と同時に開始し、5日間にわたって投与した。化合物c+anti G-CSF群は、10mg/kg/dayの化合物cの強制経口投与とG-CSF中和抗体(R&D社)(500μg/kg/day)の腹腔内投与を、骨髄移植と同時に開始し、5日間にわたって投与した。
結果を図17に示す。
実験例11及び12で示したように、抗がん剤にPAI-1阻害剤を併用すると、抗がん剤による腫瘍細胞死滅作用が増強される。ここでは、この作用にG-CSFが関与するか否かを検討した。なお、ここではPAI-1阻害剤として、化合物aを用いた。
Group 2:IM群(イマチニブ[150mg/kg/day]を強制経口投与)
Group 3:「IM+anti G-CSF」群
(イマチニブ[150mg/kg/day]を強制経口投与、
G-CSF中和抗体[500μg/kg/day]を皮下投与)
Group 4:「IM+TM」群
(イマチニブ[150mg/kg/day]と化合物a[100mg/kg/day]を強制経口投与)
Group 5:「IM+TM+anti G-CSF」群
(イマチニブ[150mg/kg/day]と化合物a[100mg/kg/day]を強制経口投与、
G-CSF中和抗体[500μg /kg/day]を皮下投与)
CML細胞を接種した日をDay 0として、各被験薬は、Day 8からDay 14まで7回投与した。結果を図18に示す。
上述の実験例11と同様に、化合物cと抗がん剤である分子標的薬イマチニブとの併用効果を検討するため、慢性骨髄性白血病モデルマウスを用いた検討を行った。
実験例11(1)の方法に従って製造した慢性骨髄性白血病モデルマウスを下記に示す3群に分けて(各群 n=15)、被験薬を投与した。
Group 2:イマチニブ群(イマチニブ[150 mg/kg/day]を強制経口投与)
Group 3:「イマチニブ+化合物c」群
(イマチニブ[150 mg/kg/day]と化合物c[10 mg/kg/day]を強制経口投与)
CML細胞を静注した日(Day 0)から8日後(Day 8)より、上記各群にそれぞれの被験薬の投与を開始した。プラセボ群及びイマチニブ群は、Day 8からDay 14まで、毎日1回計7回の被験薬投与を行った。「イマチニブ+化合物c」群については、イマチニブの投与を、Day 8からDay 14まで、毎日1回計7回行い、化合物cの投与を、Day 8からDay 14まで毎日1回計7回行った。
被験薬剤投与直前:Day 8(図19中では、[抗がん剤処理直前]と記載)、被験薬剤投与終了直後:Day 14(図19中では、[抗がん剤処理直後]と記載)及び被験薬剤投与開始後28日:Day 36(図19中では、[28日後]と記載)に骨髄に生着しているCML細胞をFACSで解析した。その結果を、図19に示す。被験薬剤投与直前:Day 8の骨髄にはおよそ50%前後の白血病細胞が生着していた(図19[抗がん剤処理直前])。この担がんマウスに被験薬剤を7回投与した時点(Day 14)でのCML細胞の割合を解析したところ、イマチニブ群も「イマチニブ+化合物c」群もCML細胞の著明な減少が確認された。さらに、経過を観察し、Day 36に生存しているマウスを再度解析したところ、イマチニブ単独投与群は再発し骨髄内の白血病が増加していた(55.5%)。一方、「イマチニブ+化合物c」群では、CML細胞の増加が認められず(1.8%)、より高い治療効果が確認された。生理食塩水投与群は全匹死亡した。
上述の実験例11と同様に、化合物aと抗がん剤である分子標的薬イマチニブとの併用効果を検討するため、慢性骨髄性白血病モデルマウスを用いた検討を行った。
実験例11(1)の方法に従って製造した慢性骨髄性白血病モデルマウスを下記に示す4群に分けて(各群 n=15)、被験薬を投与した。
Group 2:化合物a群(化合物a[100 mg/kg/day]を強制経口投与)
Group 3:イマチニブ群(イマチニブ[150 mg/kg/day]を強制経口投与)
Group 4:「イマチニブ+化合物a」群
(イマチニブ[150 mg/kg/day]と化合物a[100 mg/kg/day]を強制経口投与)
CML細胞を静注した日(Day 0)から10日後(Day 10)より、上記各群にそれぞれの被験薬の投与を開始した。プラセボ群、化合物a群及びイマチニブ群は、Day 10からDay 16まで、毎日1回計7回の被験薬投与を行った。「イマチニブ+化合物a」群については、イマチニブの投与を、Day 10からDay 16まで、毎日1回計7回行い、化合物aの投与を、Day 10からDay 16まで毎日1回計7回行った。
各群のマウスの生存率を図20に示す。これに示すように、プラセボ群(○)及び化合物a群(▽)は、実験したマウスすべてがDay 10からDay 20までに死亡した。イマチニブ群(▲)は、プラセボ群よりは長生きしたものの、Day 40までにすべてのマウスが死亡した。これに対して、「イマチニブ+化合物a」群(■)はDay 30からDay 50までの間に6匹のマウスが死亡したものの、Day 50での生存率は60%であった。
上述の実験例11と同様に、化合物d又は化合物eと抗がん剤である分子標的薬イマチニブとの併用効果を検討するため、慢性骨髄性白血病モデルマウスを用いた検討を行った。
実験例11(1)の方法に従って製造した慢性骨髄性白血病モデルマウス20匹を下記に示す4群に分けて(各群 n=5)、被験薬を投与した。
Group 2:イマチニブ群(イマチニブ[150 mg/kg/day]を強制経口投与)
Group 3:「イマチニブ+化合物d」群
(イマチニブ[150mg/kg/day]と化合物d[10 mg/kg/day]を強制経口投与)
Group 4:「イマチニブ+化合物e」群
(イマチニブ[150mg/kg/day]と化合物e[10 mg/kg/day]を強制経口投与)
CML細胞を静注した日(Day 0)から8日後(Day 8)より、上記各群にそれぞれの被験薬の投与を開始した。プラセボ群、イマチニブ群は、Day 8からDay 14まで、毎日1回計7回の被験薬投与を行った。「イマチニブ+化合物d」群及び「イマチニブ+化合物e」群については、イマチニブの投与を、Day 8からDay 14まで、毎日1回計7回行い、化合物d又はeの投与を、Day 8からDay 14まで毎日1回計7回行った。
各群のマウスの生存率を図21に示す。これに示すように、プラセボ群(○)は、実験したマウスすべてがDay 10からDay 20までに死亡した。イマチニブ群(□)は、プラセボ群よりは長生きしたものの、Day 40までにすべてのマウスが死亡した。これに対して、「イマチニブ+化合物d」群(■)及び「イマチニブ+化合物e」群(▲)はDay 25からDay 50までの間に死亡するマウスが認められたものの、Day 40以降生存するマウスも認められた。イマチニブ群に対する生存率の有意差は、「イマチニブ+化合物d」群でp=0.0054、「イマチニブ+化合物e」群でp=0.0167であり、予後が良好であるといえた。
次にPAI-1阻害剤と抗腫瘍剤を組み合わせた化学療法が、固形腫瘍についても有効であるか否かを評価するため、卵巣癌細胞を用いた実験を行った。
HER2陽性ヒト卵巣癌細胞株SKOV3(5x106個)をBALB/c-nudeマウスの皮下に接種した。マウスには、細胞の生着を良くするために、癌細胞を接種する2日前および1日前に、抗Asialo GM1抗体(和光純薬工業株式会社、Code No. 014-09801)を25μlずつ腹腔内に投与した。腫瘍径が50 mm3以上になった時点(Day 0)で、ヒト型抗HER2抗体であるハーセプチン(5 mg/kg/day)を1回腹腔内に投与すると同時に、化合物c(10 mg/kg/day)または生理食塩水の経口投与を開始した。化合物cまたは生理食塩水を、1日1回計5回(Day 0~Day 4)投与した。次週は、ハーセプチンを投与せず化合物cまたは生理食塩水のみ一週目と同様に1日1回計5回(Day 7~Day 11)投与した。ハーセプチンと化合物cを併用投与した群を「化合物c併用群」、ハーセプチンと生理食塩水を併用投与した群を「化合物c非併用群」とする。また、ハーセプチンを投与せず、生理食塩水のみを投与した群を「プラセボ群」とする。
図22に、被験薬投与後の腫瘍体積の推移を示す。化合物c併用群(点線)と化合物c非併用群(破線)の腫瘍体積は、プラセボ群(実線)と比較して縮小した。被験薬投与後20日前後から、化合物c非併用群の腫瘍体積は、化合物c併用群を比較して増加し始めた。これに対して、被験薬投与後45日目であっても、化合物c併用群の腫瘍体積は、他の群の腫瘍体積に比べて有意に小さく抑えられていた。この結果から、PAI-1阻害剤と抗腫瘍剤を組み合わせた化学療法が、抗腫瘍剤単独投与による化学療法よりも腫瘍組織の増殖抑制に有効であることが示された。
次にHER2陽性腫瘍の治療にPAI-1阻害剤と抗腫瘍剤の併用が有効であることを実証するため、HER2遺伝子を強制発現させた細胞を用いたin vivo実験を行った。
はじめに、A20細胞株(マウスBリンパ腫)にヒトHer2 cDNAをMIGR1ベクターを使用して遺伝子導入した形質転換細胞(以下、Her2-A20細胞)を作製した。Her2-A20細胞(5x106個)をBALB/c-nudeマウスの皮下に接種した。腫瘍径が30 mm3以上になった時点(Day 0)で、ヒト型抗HER2抗体であるハーセプチン(20 mg/kg/day)を1回腹腔内に投与すると同時に、化合物c(10 mg/kg/day)または生理食塩水の経口投与を開始した。化合物cまたは生理食塩水は、1日1回計5回(Day 0~Day 4)投与した。次週も同様にハーセプチン(20 mg/kg/day)を1回腹腔内投与すると同時に化合物cまたは生理食塩水の経口投与を開始した。化合物cまたは生理食塩水は、1日1回計7回(Day 7~Day 13)投与した。ハーセプチンと化合物cを併用投与した群を「化合物c併用群」、ハーセプチンと生理食塩水を併用投与した群を「化合物c非併用群」とする。また、ハーセプチンを投与せず、生理食塩水のみを投与した群を「プラセボ群」とする。n数は、化合物c併用群3匹、化合物c非併用群4匹、プラセボ群3匹である。
図23に、被験薬投与後の腫瘍体積の推移を示す。化合物c併用群(点線)の腫瘍体積は、プラセボ群(実線)および化合物c非併用群(破線)と比較して縮小した。被験薬投与15日後も、化合物c併用群の腫瘍体積は、他の群の腫瘍体積に比べて有意に小さく押さえられていた。この結果から、PAI-1阻害剤と抗腫瘍剤を組み合わせた化学療法が、抗腫瘍剤単独投与による化学療法よりもHER2陽性腫瘍組織の増殖抑制に有効であることが示された。
実験例19で使用したPAI-1阻害剤(化合物c)を化合物dに換えて、同様の実験を行った。
Her2-A20細胞(1.8x106個)をBALB/c-nudeマウスの皮下に接種した。腫瘍径が10 mm3以上になった時点(Day 0)で、ハーセプチン(20 mg/kg/day)を1回腹腔内に投与すると同時に、化合物d(10 mg/kg/day)または生理食塩水の経口投与を開始した。化合物dまたは生理食塩水は、1日1回計9回(Day 0~Day 4およびDay 7~Day 10)投与した。続いてDay 11にハーセプチン(20 mg/kg/day)を再度腹腔内投与した。化合物dまたは生理食塩水は、1日1回計5回(Day 11~Day 15)継続して投与した。ハーセプチンと化合物dを併用投与した群を「化合物d併用群」、ハーセプチンと生理食塩水を併用投与した群を「化合物d非併用群」とする。また、ハーセプチンを投与せず、生理食塩水のみを投与した群を「プラセボ群」とする。n数は、化合物d併用群3匹、化合物d非併用群4匹、プラセボ群3匹である。
図24に、被験薬投与後の腫瘍体積の推移を示す。化合物d併用群(点線)の腫瘍体積は、プラセボ群(実線)および化合物d非併用群(破線)と比較して縮小した。被験薬投与25日後も、化合物d併用群の腫瘍体積は、他の群の腫瘍体積に比べて有意に小さく押さえられていた。この結果から、異なるPAI-1阻害剤と抗腫瘍剤を組み合わせた場合であっても、HER2陽性腫瘍組織の増殖抑制に有効であることが示された。
実験例18と同様の実験を、PAI-1阻害剤を換えて行った。
HER2陽性ヒト卵巣癌細胞株SKOV3(1x107個)をマトリゲルに懸濁し、BALB/c-nudeマウスの皮下に接種した。マウスには、細胞の生着を良くするために、癌細胞を接種する2日前および1日前に、抗Asialo GM1抗体を25μlずつ腹腔内に投与した。腫腫瘍径が50 mm3以上になった時点(Day 0)で、ハーセプチン(5 mg/kg/day)、または生理食塩水を1回腹腔内に投与すると同時に、化合物d(10 mg/kg/day)の経口投与を開始した。また、ハーセプチンを投与せずに化合物d(10 mg/kg/day)のみの投与を行う群を設けた。化合物dは、1日1回計5回(Day 0~Day 4)投与した。次週は、ハーセプチンの投与は行わず化合物dまたは生理食塩水を1日1回計5回(Day 7、Day 9~Day 11およびDay 14)投与した。ハーセプチンと化合物dを併用投与した群を「化合物d併用群」、化合物dを単独で投与した群を「化合物d単独投与群」とする。また、ハーセプチンを投与せず、生理食塩水のみを投与した群を「プラセボ群」とする。
図25に、被験薬投与後の腫瘍体積の推移を示す。ハーセプチンの投与により、化合物d併用群(点線)の腫瘍体積は、プラセボ群(実線)および化合物d単独群(破線)と比較して縮小した。そして、被験薬投与後30日目であっても、化合物d併用群の腫瘍体積は、他の群の腫瘍体積に比べて有意に小さく抑えられていた。この結果から、異なるPAI-1阻害剤と抗腫瘍剤を組み合わせた場合であっても、腫瘍の治療効果が得られることが明らかとなった。化合物dについては、単独投与では、プラセボ群との間に顕著な差は認められなかった。
PAI-1のがん幹細胞での発現を以下の方法により確認した。
(1)CML細胞の回収
マウスの骨髄からビオチン標識抗体のカクテルを用いて系統マーカー(CD5、CD11b、CD45R、Gr-1、7-4、Ter119、Miltenyi Biotec社、ドイツ)陽性細胞を除去後、APC結合抗マウスc-kit(CD117)抗体(eBioscience社)、PE結合抗マウスSCA-1(Ly6A/ E)抗体(eBioscience社)で染色し、Lineage (Lin)陰性、c-Kit陽性、Sca-1陽性細胞(LSK細胞)をセルソーターで分離した。分離したLSK細胞に、実験例11で使用したp210-GFPを導入した。このp210-GFP導入細胞を、放射線照射して自己の骨髄細胞を死滅させたマウスに移植した。p210-GFP導入細胞移植されたマウスは慢性骨髄性白血病(CML)様の病態を示した。
図26Aの右上のエリアが、Lin陰性、Sca-1陽性、かつc-kit陽性(L-S+K+)の細胞であり、このエリアに分画される細胞がCML幹細胞である。左上のエリアは、Lin陰性、Sca-1陰性、c-kit陽性の細胞(L-S-K+)であり、図26Aの右下のエリアは、Lin陰性、Sca-1 陽性、c-kit 陰性の細胞(L-S+K-)であり、図26Aの左下のエリアは、Lin陰性、Sca-1 陰性、c-kit 陰性の細胞である(L-S-K-)。この3つのエリアの細胞は、幹細胞よりも分化の進んだ前駆細胞である。
(L-S+K-)、(L-S-K-)、(L-S-K+)、(L-S+K+)のエリアに分画された細胞のPAI-1の発現量を、タンパク質レベル及びmRNAレベルで比較した。図26Bは、細胞を採取した分画を示す。図23Cは、タンパク質レベルでの発現を比較した結果を示す。図26Bの上の図は、PAI-1を蛍光免疫染色して、蛍光顕微鏡観察した図である。図26Bの下のグラフは、蛍光強度を定量化したグラフである。その結果、(L-S+K-)、(L-S-K-)、(L-S-K+)、(L-S+K+)の順にPAI-1タンパク質の発現が強くなることが明らかとなった。この結果は、CML幹細胞では、分化が始まった前駆細胞よりも、PAI-1の発現が高いことを意味している。
