目的探讨缓激肽B2受体特异性拮抗剂艾替班特(HOE-140)单独或联合应用阿霉素(doxorubicin,DOX)对人卵巢癌细胞株SKOV3的影响及可能的作用机制。方法采用MTT法检测不同浓度的DOX或HOE-14与SKOV3作用24h后细胞的存活情况。在此基础上,比较二者联合用药和分别单独应用相同剂量的DOX或HOE-140对SKOV3的细胞毒作用及对SKOV3细胞凋亡的影响。结果不同浓度的DOX或HOE-140与SKOV3共同孵育24h后,均对SKOV3细胞的增殖有一定抑制作用。二者联合应用对SKOV3细胞的抑制作用明显强于单独应用(P〈0.05)。二者联合应用诱导SKOV3细胞的凋亡作用明显强于单独应用。结论缓激肽受体拮抗剂HOE-140对SKOV3细胞的增殖有一定的抑制作用,并可促进其凋亡。
Objective To investigate the inhibitory effects of B2 receptor antagonist HOE-140 alone or in combination with doxorubicin(DOX)on human ovarian cancer cell lines(SKOV3)and possible mechanisms of action.Methods SKOV3 cells were cultured in the presence of different concentrations of HOE-140 or DOX for 24 h.Then,the same concentrations of HOE-140 and DOX alone or in combination were used to observe the synergistic interaction and the influence on apoptosis of SKOV3 cells.Results Both HOE-140 and DOX inhibited the proliferation of SKOV3 cells in a concentration-dependent manner.The effect of combination on SKOV3 cells showed a synergistic effects(P0.05).The combination effect of the two drugs was stronger than medication alone.Conclusion Bradykinin receptor antagonist HOE-140 inhibited the proliferation of SKOV3 cells and can promote apoptosis.
