To investigate whether AZD1152 (AZD), the selective inhibitor of aurora kinase B, may play a role in the treatment of cisplatin-resistant ovarian carcinoma when administrated alone or in combination with cisplatin.


Hey (cisplatin-resistant ovarian cancer cell line) cells were analyzed. According to the treatment plan, Hey cells were divided into four groups (AZD group, cisplatin group, AZD + cisplatin group and control group). Methyl thiazolyl tetrazolium (MTT) assay was used to test the cells proliferation, caspase-3/7 activity analysis was used to analyze cells apoptosis, and fluorescence in-situ hybridization (FISH) assay was used to determine the copy the number of chromosome 7 and checked the copy numbers of hTERC gene and C-myc gene.


MTT test showed that proliferation of AZD group was lower than that in control group (P < 0.01). The cells proliferation with the treatment with 10 and 20 nmol/L AZD for 24 hours was (81.4 ± 3.6)% and (81.4 ± 3.6)% respectively, and the cells proliferation for 48 hours was (43.1 ± 2.0)% and (38.5 ± 1.6)% respectively, which was significantly lower than control group (100%, P < 0.01); Treated with the same concentration of AZD, inhibition of proliferation was significantly enhanced as the time extended (P < 0.01). Proliferation in group AZD + cisplatin was lower than that in cisplatin group (P < 0.01) which suggest that there were additive effects after combined AZD with cisplatin. Compared with control group, caspase-3/7 activity in AZD group increased significantly (P = 0.000), and the same results was seen between AZD + cisplatin group and cisplatin group or AZD group (all P < 0.01). Compared with cisplatin group or control group, the copy numbers of hTERC, C-myc and the number of chromosome were significantly increased in AZD group and AZD + cisplat group (all P < 0.05).


AZD could inhibit ovarian cancer cells proliferation and induce cells apoptosis significantly. AZD alone or in combination with cisplatin may result in the increased cells polyploidy.
