Effect of Abnormal Savda Munziq on MDR and Expression of mRNA of Bel/Fu Cell Line / 中国中医药信息杂志

Objective To study the effect of Abnormal Savda Munziq (ASMq) on MDR and expression of mRNA of Bel/Fu cell line. Methods Several genes expression including MDR1, MRP, TOPOII? and GST-? were analyzed by RT-PCR. Results ASMq has been found to down-regulate MDR1 gene and simultaneously up-regulate TopoⅡ?mRNA. Conclusion ASMq can reverse the drug resistance against 5-Fu in Bel/Fu cells. Inhibition of MDR1 mRNA and up-regulate TopoⅡ? mRNA may contribute to the mechanisms.
