摘要 目的:检测姜黄素与顺铂单独及联合作用对SKOV3、3AO细胞体外生长及其对Notch1/Hes1信号mRNA表达变化的影响,证实姜黄素通过Notch信号途径影响卵巢癌细胞增殖及可能通过Notch信号途径增加顺铂的化疗敏感性。方法:采用RT-PCR检测姜黄素与顺铂单独及联合作用于人卵巢癌细胞株3AO,SKOV3对Notch1,Hes1信号表达的影响。结果:1 RT-PCR分别检测经不同浓度姜黄素及顺铂处理后的Notch1,Hes1信号表达,灰度分析结果作单因素方差分析,姜黄素组与阴性对照组比较,组间及组内差异均有显著性差异(P<0.05),姜黄素下调目的基因条带的表达。顺铂组与阴性对照组比较有显著性差异(P<0.05),顺铂增强Notch1,Hes1信号表达;2RT-PCR检测经不同浓度(80、40、20μg/ml)姜黄素联合顺铂1.25μg/ml处理后的Notch1,Hes1信号表达,与姜黄素单独作用比较,灰度分析结果作单因素方差分析有显著性差异(P<0.05)。联合用药下调目的基因条带的表达,其可能通过干预Notch1-hes1信号途径发挥协同作用。结论:Notch1信号与肿瘤增殖相关,姜黄素可能通过干预癌细胞的Notch1-hes1信号途径抑制肿瘤细胞的增殖,增加化疗敏感性,与顺铂发挥协同作用。
