Effect of embelin and doxorubicin on the proliferation of MCF-7 cell and growth of MCF-7 bearing nude mice / 中国生化药物杂志

ABSTRACT

Objective To explore the effect of X-linked inhibitor of apoptosis protein(XIAP)combined with doxorubicin on the proliferation of MCF-7 cell and growth of MCF-7 bearing nude mice.Methods The anti-proliferation efficiency of doxorubicin and embelin were determined by MTT assay.MCF-7 cell apoptosis induced by embelin and doxorubicin were detected by Flow cytometry.Anti-tumor ability of embelin and doxorubicin were evalued with tumor spheroids test.MCF-7 cell were xenografted to mice to establish the animal model,which was used to evaluate the effect of anti-tumor. Results Compared with saline group,embelin group and doxorubicin group,the combination(doxorubicin +embelin)group inhibited the growth of MCF-7 cells effectively(P<0.01).The combination group induced the apoptosis of MCF-7 cells more effectively than doxorubicin alone(P<0.01), and significantly inhibit the growth of tumor in vitro and in vivo than other groups(P<0.01).Conclusion The combination of doxorubicin and embelin may be used as a potentially effective treatment method for breast cancer.
