Abstract
前列腺癌 (prostate cancer) 普遍發生在西方男性身上。近年來,根據行政院衛生署的統計,國人前列腺癌的發生率及死亡率逐年攀升,對男性造成嚴重的危機。許多文獻證實在薑黃 (turmeric) 中主要活性成分薑黃素 (curcumin) 具有抗氧化、抗發炎、抗腫瘤及轉移、誘導細胞計畫性死亡、及抗脂質過氧化等活性,但卻因生體可用率低及水溶性差等特性難以應用在生物體內,許多科學家陸續以薑黃素做為前驅物,期盼能找到具有臨床應用價值之類似物。本篇研究探討薑黃素類似物抑制前列腺癌之效果,經由雄性素受體調控冷光酵素活性試驗,篩選出其薑黃素結構類似物 No.2 具有顯著抑制雄性素受體的能力;同時也經由細胞存活率試驗,發現薑黃素結構類似物 No.2 具有濃度及時間依存性的抑制前列腺細胞增生。此外,利用細胞免疫染色及蛋白質表現量可證明薑黃素結構類似物 No.2 能誘導自體吞噬及細胞凋亡。在動物模式上,使用 PC-3 細胞原位接種之人類前列腺癌為對象,並以尾靜脈注射方式投予薑黃素結構類似物 No.2 於雄性裸鼠體內,實驗結果顯示薑黃素結構類似物 No.2 具有顯著抑制腫瘤生長之生物活性。
