摘要 目的探讨二甲双胍和2-脱氧—葡萄糖协同抑制三阴性乳腺癌干细胞及CD44表达。方法二甲双胍和2-脱氧—葡萄糖分别或联合与三阴性乳腺癌细胞株MDA-MB-231培养,用CCK8检测活细胞的比例,免疫荧光法联合流式细胞仪检测乳腺癌干细胞的比例和CD44的表达。结果二甲双胍和2-脱氧—葡萄糖各自对MDAMB-231细胞均有抑制作用,对其干细胞无选择性杀伤作用,对CD44的表达有明显抑制,呈时间依赖性;二甲双胍和2-脱氧—葡萄糖联合对乳癌干细胞无选择性杀伤作用,对CD44表达的抑制强于单药的作用。结论二甲双胍和2-脱氧—葡萄糖单独或联合对三阴性乳腺癌干细胞无选择性杀伤,但是对CD44表达的有抑制作用。
