摘要 目的探讨常山酮抑制乳腺癌脑转移的作用。方法本实验分为溶剂组及常山酮组,以人乳腺癌细胞MDAMB-231及BALB裸鼠为研究对象,首先通过体外实验,使用MTT法、划痕试验及Western blot观察各组MDA-MB-231增殖、迁移及bax、bcl-2、cleaved-caspase3等凋亡相关蛋白的表达情况;然后制备乳腺癌脑转移模型,通过神经功能评分及脑部HE染色观察各组脑转移情况。结果常山酮显著抑制了MDA-MB-231的增殖和迁移能力,增加了bax及cleaved-caspase3蛋白的表达水平,并减少了MDA-MB-231向脑部的定植。结论常山酮可能通过抑制细胞增殖及迁移、促进凋亡等机制抑制乳腺癌细胞脑转移。
