Abstract
本研究主要以黑色素瘤細胞誘導轉移之動物及黑色素瘤細胞探討十字花科蔬菜衍生物indole-3-carbinol (I3C)、phenylethyl isothiocyanate (PEITC)對黑色素瘤誘發轉移的影響。動物實驗結果顯示,給予I3C及I3C與PEITC混合,雖與控制組無統計上的差異但肺臟上黑色素瘤結節平均數有降低的情形,且組織切片發現黑色素瘤(foci)較小;PEITC的給予,黑色素瘤結節數與控制組亦無統計上的差異,且foci大小也與控制組相近。細胞實驗結果顯示I3C組可隨濃度及培養天數增加而顯著抑制癌細胞增殖作用,且發現於培養第六天,細胞培養液中黑色素含量顯著增加及細胞型態較膨大表示細胞有分化的現象產生;而PEITC則無顯著抑制細胞增殖作用;coated 玻尿酸(hyaluronan, HA)黏附作用上,添加I3C、PEITC及兩種混合於1-2小時內,皆可顯著抑制細胞與HA的黏附,但經過24小時後,PEITC組則無法持續作用。於coated Matrigel 實驗,發現I3C (125 μM及150 μM )及混合組有輕微抑制細胞黏附且與控制組有顯著差異。由以上得知,I3C具有抑制癌症轉移的潛力,而PEITC抑制轉移效果有限,不過當兩種物質的混合較I3C單獨抑制作用稍佳,顯示著具加成或協同作用,更貼近由天然食物攝取營養素的原則。
