摘要: 目的探讨Genistein对耐药卵巢癌细胞SKOV3增殖、凋亡和顺铂敏感性的影响。方法采用MTT法检测Genistein单用及合用顺铂对细胞增殖的影响,流式细胞仪分析Genistein及Genistein联合顺铂对细胞周期和凋亡的影响。结果Genistein对SKOV3细胞增殖表现出浓度依赖性的抑制作用,并显著提高了其对顺铂的敏感性(P<0.05);0.625～5μg/ml顺铂与2.5～10μg/mlGenistein合用基本表现为协同作用。5、10μg/mlGenistein均可将细胞阻滞于G2/M期并诱导一定程度的凋亡,10μg/mlGenistein还可进一步的干扰S期进程;当顺铂与Genistein合用时,两种药物在干扰SKOV3细胞周期和诱导凋亡方面表现为显著的协同效应。结论Genistein能够抑制耐药卵巢癌细胞SKOV3的增殖,并显著增强该细胞对顺铂的敏感性。Abstract: Objective To study the effects of genistein on proliferation, apoptosis and cisplatin sensitivity of drug-resistant ovarian carcinoma cell skov-3. Methods MTT assay was used to analyze growth inhibitory effect of genistein alone and with cisplatin on SKOV-3 cell. Cell cycle arrest and apoptosis was meas-ured by flow cytometry (FCM). Results Genistein exerted inhibitory effect on SKOV-3 cell in a concen-tration-dependent way and significantly enhanced its sensitivity to cisplatin(P< 0.05). Generally, cisp...
