布托啡诺逆转ABCB1 蛋白诱导的白血病多重耐药的 效果和机制
【目的】研究布托啡诺在临床使用剂量范围内通过抑制ABCB1的转运功能增加白血病耐药细胞的化 疗药物敏感性。【方法】采用HL60及其ABCB1过表达的耐药细胞株HL60/VCR、K562及其ABCB1过表达的耐药 细胞株K562/ADR 均在培养环境中加入含胎牛血清的DMEM 或RPMI-1640的培养液中进行培养。采用MTT法 检测布托啡诺的细胞毒性,通过流式细胞仪检测阿霉素(DOX)在HL60/VCR细胞内的累积程度;加入布托啡诺 培养72 h后用免疫荧光观察ABCB1在细胞膜表面的形态和分布变化以及采用Western Blotting检测ABCB1的表达 水平。【结果】布托啡诺能...
