Fig. 1 DAB2IP prevents premature mitotic exit and maintains MCC stability. DAB2IP-proﬁcient and -deﬁcient C4-2 (C4-2 D2 and C4-2 Neo cells) (A) and PC3 (PC3 siCtrl cells and siD2) (B) cells were synchronized in prometaphase using nocodazole (50 ng/ml) and then released into fresh media. Cells were collected at the indicated times after release. The expression of DAB2IP, Cyclin B1, Securin, and HSP70 were detected via immunoblotting. <t>Cdc20</t> and APC/C complex were immunoprecipitated from nocodazole-blocked C4-2 D2 and Neo (C), and from DAB2IP- knockdown PC3 and its control (D) prometaphase cells lysates. The amounts of Mad2 and BubR1 binding with Cdc20 and Cdc27 were determined by immunoblotting.

A, B C4-2 D2 cells were synchronized at prometaphase and the mitotic cells were collected by the shake-off method. Cells lysates were immunoprecipitated with anti-DAB2IP (A) or anti-Cdc20 (B) or IgG antibodies, and the interaction with Cdc20, DAB2IP, Cdc27, BubR1, and Mad2 were analyzed by immunoblotting. C Schema of different truncated domains of DAB2IP. D, E Various truncated cDNA constructs of DAB2IP were co-transfected with HA-Cdc20 into HeLa cells. HeLa cells were then synchronized at prometaphase and the mitotic cells were collected by the shake-off method. Cells lysates were immunoprecipitated with anti-Flag with antibody.

Fig. 4 DAB2IP-deﬁcient prostate cancer cells are sensitive to Mps1 inhibitor. A Paired C4-2 cells were exposed to indicated concentrations of AZ3156, a speciﬁc Mps1 inhibitor, for 48 h and MTT assay was performed. Results obtained were from three independent experiments (means ± SD; ***P < 0.001 and *P < 0.05 as compared with Neo cells). B 1 × 104 cells were seeded in 35 mm2 dishes at day 0, cells were treated with or without AZ3156 (0.5 μM) and cells were counted to determine cell proliferation rates at indicated days (1, 2, and 3 days) (means ± SD; *P < 0.05, ***P < 0.001 as compared with untreated cells). C C4-2 D2 and Neo cells were arrested at prometaphase and treated with 0.5 and 1 μM of AZ3156 along with nocodazole for an additional 2 h. APC/C complex was immunoprecipitated from C4-2 D2 and Neo cells lysates treated or untreated with Mps1 inhibitor.

D C4-2 Neo and D2 cells were treated with 10 μM MG132 for 4 h, then treated with or without 0.5 μM AZD3156 along with MG132 for an additional 2 h. Chromosome alignment was determined by immunoﬂuorescent staining using anti-α-tubulin and Crest antibody; DNA was visible by DAPI. Scale bars are 5 μm. E Proportion of cells with chromosome-missegregation and misalignment in C4-2 Neo and C4-2 D2 cells treated with or without AZD3156 are presented as the mean and SD from three independent experiments (**P < 0.01, ***P < 0.001 as compared with Neo cells). F Cells were exposed to 1 μM of AZD3156 for 24 h and subjected to immunoblotting with anti-PARP, anti-DAB2IP, and anti-Actin antibodies.
