Abstract
子宮內膜癌 (endometrial cancer)及卵巢癌 (ovarian cancer)好發於停經後的婦女,在歐美國家是常見的癌症,在台灣因女性普遍使用賀爾蒙補充治療,其發生率也攀升至婦科癌症的第一名。近幾年西方國家開始普遍使用中草藥療法,異甘草素 (isoliquiritigenin, ISL)為從甘草植物中萃取出之黃酮類 (flavonoid)活性化合物,先前的研究結果發現,異甘草素具有抗氧化、抗發炎以及抑制腫瘤的效果,而本研究想要探討異甘草素對人類子宮內膜癌及卵巢癌細胞的抗腫瘤效果。分別利用子宮內膜癌細胞株HEC-1A、RL95-2及卵巢癌細胞株OVCAR5和ES-2進行研究,分別介入異甘草素後,觀察其細胞增生、細胞週期、細胞凋亡 (apoptosis)和細胞自噬 (autophagy)相關蛋白之表現量,最後以傷口癒合試驗來觀察異甘草素對癌細胞的抑制效果。實驗結果發現:1. 異甘草素不管在劑量效應還是時間效應上,都能夠顯著抑制癌細胞的生長;2. 異甘草素能夠造成細胞週期停滯於G2/M期;3. 異甘草素會促進細胞凋亡及細胞自噬作用相關蛋白LC3BⅡ的表現量增加;4. 異甘草素會抑制子宮內膜癌細胞的移行能力 (migration)。從本研究結果可以得知,異甘草素對於抑制子宮內膜癌及卵巢癌細胞生長具有多重效果,在治療子宮內膜癌及卵巢癌方面非常具有潛力。
