本発明の併用療法により、効率的に各種癌細胞の増殖を抑制し、癌を処置または治療することができる。
本発明により、癌治療において、化学療法剤の投与量を大幅に低減することができ、化学療法剤による副作用リスクを低減しつつ抗癌治療を行うことができる。
本発明の一側面は、HSP47の阻害物質を含む医薬、例えば、HSP47の発現の阻害剤を含む、癌患者の化学療法剤感受性を増強するための医薬に関する。
HSP47遺伝子の塩基配列およびアミノ酸配列は、当該技術分野で公知であり、本発明において、HSP47のmRNA配列は、配列番号1によって示される。
本明細書において、「数個」とは、2~10個、好ましくは2~5個、より好ましくは2~3個の塩基数をいう。また、配列同一性は、例えばBLASTなどの公知のアルゴリズムを使用して決定することができる。
本発明において、「相補的」とは、核酸が、他の核酸配列と、古典的なワトソン-クリック型か、または他の非古典的なタイプにより水素結合を形成できることを意味する。
また、本発明において、「実質的に相補的」とは、核酸配列の全ての連続する残基が、他の核酸配列における同じ数の連続する残基と水素結合を形成する場合のみならず、核酸配列の全ての残基のうち、例えば、70%、80%、および90%の残基が、他の核酸配列の残基と水素結合を形成する場合も含む。
したがって、本発明において、siRNAは、HSP47遺伝子の転写体RNAの一部に100%相補的なヌクレオチドから数塩基変更されているヌクレオチドを含むアンチセンスRNAを有していてもよい。
また、本発明において、センスRNAとアンチセンスRNAの各3'末端には、2~5ヌクレオチド、好ましくは2ヌクレオチドの突出末端を有していてもよい。また、本発明において、siRNAは、修飾siRNAであってもよい。

センス鎖の5’- GGACAGGCCUCUACAACUAtt -3’(配列番号6)とアンチセンス鎖の5’- UAGUUGUAGAGGCCUGUCCtt -3’(配列番号7)の組合せ(siHSP47-C)(日東電工株式会社において作成)
ウイルスベクターを使用する場合、ウイルスの力価としては1×103~1×1015p.f.u.(プラーク形成単位)であってもよく、好ましくは1×105~1×1013、より好ましくは1×107~1×1011、さらに好ましくは1×108~1×1010で用いることができる。
HSP47の阻害物質を併用したときに化学療法剤に対する感受性が増加しているか否かは、HSP47の阻害物質を使用しないで癌細胞の生存率を50%に誘導するために必要な化学療法剤の濃度と比較したときに、より低い濃度で50%生存率を誘導できるか否かによって判断する。HSP47の阻害物質を使用しないで癌細胞の生存率を50%に誘導するために必要な化学療法剤の濃度の相対値を100としたときに、化学療法剤濃度の相対値が100未満であると感受性が増加しているといえ、50未満であると著しく増加しているといえる。化学療法剤濃度の相対値が50未満であると、化学療法剤による副作用のリスクを低減しつつ抗癌治療を行うことができる。
癌細胞の生存率は、HSP47の阻害物質や化学療法剤による処理の前の癌細胞の数を100%としたときに、生存している癌細胞の数の相対値(%)を示しており、色素排除法(Dye-exclusion assay)によって測定することができる。色素排除法(Dye-exclusion assay)は、例えば、トリパンブルー染色の有無により細胞の生死を判断し、生存細胞数を測定することができる。トリパンブルー染色による色素排除法は、例えば、0.4%トリパンブルー溶液(販売元:富士フィルム和光純薬株式会社、商品コード:20717081)と、細胞を培養培地に浮遊させた細胞浮遊液とを等量混和し、血球計算盤上において、染色された細胞と染色されていない細胞の数を数えることにより行うことができる。
化学療法剤としては、細胞透過性抗癌剤などの、癌治療に用いられる化学療法剤が好ましく、細胞透過性抗癌剤としては、限定されずに、殺細胞作用や増殖阻害作用などの細胞障害作用を有する化学療法剤、例えば、アルキル化剤、代謝拮抗剤(例えば、5-フルオロウラシル、ゲムシタビン)、抗腫瘍性抗生物質、アルカロイド、ホルモン療法剤、白金錯体(例えば、シスプラチン)、血管新生阻害剤、トポイソメラーゼ阻害剤、および微小管作用薬などが挙げられる。これらの中でも、アルキル化剤、代謝拮抗剤、抗腫瘍性抗生物質、白金借体またはトポイソメラーゼは、DNA合成阻害やDNA損傷を誘導し、小胞体ストレスを誘導することができる化学療法剤であり、HSP47の阻害物質との併用で、化学療法剤による抗癌作用が特に増強される点で好ましい。本発明の医薬において、HSP47の阻害物質と、シスプラチンまたは5-フルオロウラシルとの組み合わせが最も好ましい。これらを組み合わせて投与する場合、HSP47の阻害物質の好ましい濃度は、最終濃度が1nM~100nMであり、シスプラチンおよび5-フルオロウラシルの好ましい濃度は、5μM~100μMである。
本発明は、本発明の医薬に含まれ得る活性成分(例えば、HSP47の阻害物質)および必要に応じて化学療法剤を、単独でもしくは組み合わせて含む1個または2個以上の容器を含む組成物の調製キット、ならびに、そのようなキットの形で提供される医薬の必要構成要素にも関する。本発明のキットは、上記のほか、本発明の医薬の調製方法や投与方法などが記載された指示、例えば説明書や、CD、DVD等の電子記録媒体等を含んでいてもよい。
本発明の一態様は、HSP47の阻害物質を投与することを特徴とする、癌患者の化学療法剤に対する感受性を増加させるための方法(化学療法剤感受性増強方法)に関する。
投与頻度は、用いる剤や組成物の性状や、上記のものを含む対象の条件によって異なるが、例えば、1日多数回(すなわち1日2、3、4回または5回以上)、1日1回、数日毎(すなわち2、3、4、5、6、7日毎など)、1週間毎、数週間毎(すなわち2、3、4週間毎など)であってもよい。
本発明の併用療法においては、HSP47の阻害物質と化学療法剤を、別々に投与してもよいし、同時に投与してもよいが、別々に投与する場合には、HSP47の阻害物質を先に投与することが好ましい。HSP47の阻害物質の投与後に化学療法剤を投与する場合には化学療法剤の投与は、HSP47の阻害物質の投与の1時間~70時間後が好ましく、2時間後~60時間後がより好ましく、4時間後~50時間後が特に好ましい。HSP47の阻害物質の投与から、4時間後~50時間後に化学療法剤を投与すると、HSP47のタンパク質の発現低下が十分に発揮された状態で化学療法剤による癌治療ができるため、癌細胞の生存率を著しく低下することができる。
また、用語「処置」は、本明細書で用いる場合、疾患の治癒、一時的寛解または予防などを目的とする医学的に許容される全ての種類の予防的および/または治療的介入を包含するものとする。例えば、「処置」の用語は、疾患の進行の遅延または停止、病変の退縮または消失、発症の予防または再発の防止などを含む、種々の目的の医学的に許容される介入を包含する。
また、本発明により、癌治療において、化学療法剤の投与量を大幅に低減することができ、化学療法剤による副作用リスクを低減しつつ抗癌治療を行うことができる。
したがって、本発明はまた、HSP47の阻害物質を含む、上記作用を提供するための医薬、上記作用を提供するための医薬の製造における使用、ならびに、HSP47の阻害物質の上記作用を提供するための使用にも関する。

Rep.2017 Aug 24 7(1); 9389)。ヒトHSP47ゲノムのエクソン2について特異的に設計したgRNA配列(5’-CCGACTGTACGGACCCAGCTCAG-3’ (配列番号8))を、pCG SapIベクターに挿入した。構築した標的化ベクターおよびpcDNA3.1(+)を、Lipofectamine 2000 (Thermo Fisher Scientific)を使用して、癌細胞(SW480、HCT116、PANC1、Suit2、MIA-PaCa-2、MDA-MB-231)に共トランスフェクトした。細胞を、10%FBSおよびG418 (1000μg/mL)で補充したDMEM培地で培養し、HSP47を安定してサイレンシングする細胞株を選択した。DNA配列決定分析により、単一の細胞クローンを評価し、標的対立遺伝子中のインデル(挿入/欠失)を検出した。また、選択したクローンにおけるHSP47タンパク質の発現レベルをウエスタンブロッティングによって確認した。対照細胞クローン(mock)は、空ベクターをトランスフェクトすることによって作成した。
例2,3でトランスフェクトした癌細胞を、1、5、10、20、50μMの濃度のシス-ジアミンジクロロ白金(II)(CDDP, Sigma-Aldrich)、または、1、5、10、20、50μMの濃度の5-フルオロウラシル(Wako Pure Chemical, Tokyo, Japan)で24時間処理した。処理した細胞の生存率は、色素排除法(Dye-exclusion assay)によって決定した。
