摘要
目的:研究夏枯草口服液对雌激素受体(ER)阳性人乳腺癌细胞凋亡的影响。方法:将ER阳性型人乳腺癌细胞系MCF-7及ER阴性型人乳腺癌细胞系MDA-MB-231、SK-BR-3分别与不同浓度(0、25、50、100 mg/ml)的夏枯草口服液提取物共孵育。采用噻唑蓝(MTT)法检测细胞存活率;流式细胞术及Annexin V/PI双染色检测细胞周期和细胞凋亡;ELISA法检测雌激素应答基因表达量;Western blot法检测ERα蛋白表达情况。结果:1夏枯草口服液提取物呈剂量依赖性地抑制MCF-7细胞的生长,但对MDAMB-231、SK-BR-3细胞无显著作用。2夏枯草口服液提取物可诱导MCF-7细胞产生凋亡,在mRNA水平降低MCF-7细胞内雌激素应答基因的表达,并降低ERα蛋白表达。结论:夏枯草口服液可诱导ER阳性乳腺癌细胞的凋亡,用于治疗ER阳性乳腺癌。
