Abstract
Description
また、これまでの方法では、ALA類を生理食塩水等に溶解させて対象へ経口投与していたが、ALA類には苦みがあり、投与後に対象が嘔吐してしまうなど、対象への負担が大きかった。そこで、本発明者らは、ALA類と併用することでALA類の苦みを軽減することができ、さらに、ALA−PDT又はALA−PDDの効果を増強させる(すなわち、上記の2つの課題を同時に解決し得る)効果を有する食品や飲料を鋭意検討した。
癌細胞として、ヒト胃がん細胞株であるTMK−1を用いた。培地は、RPMI−1640(Wako社製)に非働化ウシ胎児血清(FBS)を10%添加したものを用いた(以下RPMI培地と表記する)。柑橘類成分として、柑橘エキス粉末(温州ミカンエキス、オリザ油化株式会社製)を用いた。
図2に示すように、ALA塩酸塩単独処理と比べて、柑橘エキスを併用すると、添加量依存的に細胞内PpIXが増加し、ALA塩酸塩+1mg/mL柑橘エキス(ノビレチン3.8μM相当量)の添加により、最大で2倍増加した。この結果から、ALAと柑橘類成分の併用により、ALA単独使用の場合と比較して、細胞内PpIXの蓄積が増強されることが示された。また柑橘エキスはノビレチンを含んでいることから、柑橘エキス中のノビレチンがPpIX蓄積増強効果に関与している可能性が示唆された。
癌細胞としてヒト胃がん細胞株であるTMK−1を用いた。ノビレチン(Wako社製)はDMSOに溶解し、1mMノビレチン溶液とした。1mMノビレチン溶液を等量のDMSOで希釈、2倍希釈系列を作成し、ノビレチン溶液とした。これらのノビレチン溶液をRPMI培地、または、2.3 mM ALA塩酸塩を含むRPMI培地で100倍希釈し、0−10μMノビレチン含有培地を作成した。FTCをDMSOに溶解し1mM FTC溶液を作成後、2.3 mM ALA塩酸塩を含むRPMI培地で希釈し、2.3 mM ALA塩酸塩+10μM FTC培地を作製しこれをポジティブコントロール(PC)とした。
図3から明らかなように、ALA塩酸塩単独添加と比べて、ノビレチンを併用すると細胞内PpIXが濃度依存的に増加し、10μMノビレチンの添加により最大で2倍増加した。この結果から、ALAとノビレチンとの併用により、ALA単独使用の場合と比較して、細胞内PpIXの蓄積が増強されることが示された。
癌細胞としてヒト胃がん細胞株であるTMK−1を用いた。癌細胞は5×103cells/wellを96well plateに播種後、37℃で一晩培養した。培養後、13.8mM ALA塩酸塩を含むRPMI培地と、60μMノビレチンを含むRPMI培地とを1/6量ずつ添加し、2.3mM ALA塩酸塩と10μMノビレチン共存下で4時間培養した。4時間培養後、培養上清を除去、細胞をPBSで洗浄し、100μLのRPMI培地を各ウェルに添加、PDT照射装置を用いて波長631nmにて5分間照射し、PDTを行った。
図4から明らかなように、PDT処理群の細胞生存率は、2.3mM ALA塩酸塩単独処理区が63%であったのに対し、2.3mM ALA塩酸塩+10μMノビレチン併用処理区は18%と顕著に低下していた。一方、PDT未処理群は、いずれの処理区も95%以上の細胞生存率を示した。この結果から、ALAとノビレチンとの併用により、ALA単独使用の場合と比較して、ALA−PDTの殺細胞効果が増強されることが示された。
癌細胞として、マウスの乳腺腫瘍であるEMT−6を用いた。培地は、Waymouth’s MB 752/1 Medium,Liquid(Life Technologies社製)に非働化ウシ胎児血清(FBS)を10%添加したものを用いた(以下Waymouth’s培地と表記する)。ノビレチンは、ノビレチン粉末(フナコシ社製)を用いた。
白色有精卵(後藤鶏卵場)の卵殻を70%エタノール綿で消毒後、37℃のインキュベーターに卵を縦置き(気室部位を上)にしてDay 11までインキュベートした。培養中、適時転卵を行った。
図6に示すように、ALA塩酸塩単独処理と比べて、ノビレチンを併用すると、腫瘍重量が減少した。この結果から、ALAとノビレチンの併用により、ALA単独使用の場合と比較して、ALA−PDTによる抗腫瘍効果が増強されることが示された。
