黄芪多糖降低A549/DDP肺腺癌细胞顺铂耐药机制研究
发布时间:2021-04-09 01:39
目的:研究黄芪多糖对A549/DDP肺腺癌细胞顺铂耐药的影响及可能机制。方法:将A549/DDP顺铂耐药肺腺癌细胞分为CON组(未行黄芪多糖及顺铂处理)、APS组(仅用黄芪多糖处理)、DDP组(仅用顺铂处理)及A+D组(黄芪多糖联合顺铂处理),比较四组细胞增殖、细胞周期及凋亡率和耐药基因表达的差异。结果:A+D组细胞d1-d7吸光度、S期、G2/M期和PI均显著低于CON组、APS组和DDP组细胞(均P<0.05),G0/G1期和凋亡率均显著高于CON组、APS组和DDP组细胞(均P<0.05);APS组和A+D组细胞MDR1和MRP基因mRNA表达无明显差异(均P>0.05),且均显著低于CON组和DDP组(均P<0.05)。结论:黄芪多糖可显著改善A549/DDP肺腺癌细胞对顺铂耐药性,可能与黄芪多糖显著降低MDR1和MRP有关。
