トラネキサム酸を250μM又は500μMの濃度で添加した培地にて、中胚葉由来であるヒト皮膚線維芽細胞を24時間培養した後、細胞中のサーチュイン1のmRNA発現量(GAPDHにより標準化)をリアルタイムPCR法により測定した。コントロールとしてトラネキサム酸が無添加の培地で培養した細胞におけるサーチュイン1のmRNA発現量を同様に測定した。結果はコントロールの発現量を1とした相対値として図1に示した。
トラネキサム酸を250μM又は500μMの濃度で添加した培地にて、外胚葉由来であるヒト表皮角化細胞を24時間培養した後、細胞中のサーチュイン1のmRNA発現量(GAPDHにより標準化)をリアルタイムPCR法により測定した。コントロールとしてトラネキサム酸が無添加の培地で培養した細胞におけるサーチュイン1のmRNA発現量を同様に測定した。結果はコントロールの発現量を1とした相対値として図2に示した。
トラネキサム酸を250μM又は500μMの濃度で添加した培地にて、HeLa細胞を24時間培養した後、細胞中のサーチュイン1のmRNA発現量(GAPDHにより標準化)をリアルタイムPCR法により測定した。コントロールとしてトラネキサム酸が無添加の培地で培養した細胞におけるサーチュイン1のmRNA発現量を同様に測定した。結果はコントロールの発現量を1とした相対値として図3に示した。
UVA暴露なし又はUVA連続曝露(3J/cm2、4日間)により光老化を誘導したヒト皮膚線維芽細胞を、250μM又は500μMのトラネキサム酸を添加した培地で24時間培養した後、SA-βガラクトシダーゼ染色を行い、SA-βガラクトシダーゼを視覚化した。比較としてトラネキサム酸が無添加の培地で培養した細胞のSA-βガラクトシダーゼを視覚化した。得られた画像は図4に示した。
UVA暴露なし又はUVA連続曝露(3J/cm2、4日間)により光老化を誘導したヒト皮膚線維芽細胞を、250μM又は500μMのトラネキサム酸を添加した培地で24時間培養した後、細胞内ROS検出試薬である2´,7´-Dichlorodihydrofluorescein diacetate (H2DCFDA)を用いて細胞内ROSレベル(タンパク量により標準化)を測定した。比較としてトラネキサム酸が無添加の培地で培養した際の細胞内ROSレベルを同様に測定した。結果はUVA暴露なし/トラネキサム酸添加なしの場合の細胞内ROSレベルを100とした相対値として図5に示した。
UVA暴露なし又はUVA連続曝露(3J/cm2、4日間)により光老化を誘導したヒト皮膚線維芽細胞を、500μMのトラネキサム酸を添加した培地で24時間培養した後、培養上清中のI型コラーゲン量(タンパク量で標準化)をELISA法により測定した。比較としてトラネキサム酸が無添加の培地で培養した際のI型コラーゲン量を同様に測定した。結果は図6に示した。
UVA暴露なし又はUVA連続曝露(3J/cm2、4日間)により光老化を誘導したヒト皮膚線維芽細胞を、500μMのトラネキサム酸を添加した培地で24時間培養した後、細胞内のMMP1mRNA発現量(GAPDHにより標準化)をリアルタイムPCR法により測定した。比較としてトラネキサム酸が無添加の培地で培養した細胞のMMP1のmRNA発現量を同様に測定した。結果はUVA暴露なし/トラネキサム酸添加なしの場合の発現量を1とした相対値として図7に示した。
UVA暴露なし又はUVA連続曝露(3J/cm2、4日間)により光老化を誘導したヒト皮膚線維芽細胞を、トラネキサム酸を500μMの濃度で添加した培地で24時間培養した後、細胞内のCOL1A1mRNA発現量(GAPDHにより標準化)をリアルタイムPCR法により測定した。比較としてトラネキサム酸が無添加の培地で培養した細胞のCOL1A1のmRNA発現量を同様に測定した。結果はUVA暴露なし/トラネキサム酸添加なしの場合の発現量を1とした相対値として図8に示した。
