    Figure Legends
    Figure 1 CIZ1 is up-regulated in bladder cancer specimens and cells.
    (A) CIZ1 expression in bladder cancer (n=20) and normal tissues (n=6) was determined by immunohistochemistry assays.
    (B) Quantification of CIZ1 expression in A.
    (A and B) T24 cells expressing shCtrl or shCIZ1 lentivirus were subjected to qRT-PCR and western blot analysis of CIZ1. GAPDH serves as internal control. **p < 0.01.
    (C and D) 5637 cells expressing shCtrl or shCIZ1 lentivirus were subjected to qRT-PCR and western blot analysis of CIZ1. GAPDH serves as internal control. **p < 0.01.
    Figure 3 CIZ1 knockdown suppresses the proliferation of T24 and 5637 cells.
    (A and B) Multiparametric high-content screening analysis of shCtrl or shCIZ1 T24 cells from day 1 to day 5 after seeding. (A) Representative images of HCS. (B) Quantification of the HCS as shown in A.***p < 0.001.

    (F) Cell proliferation of shCtrl or shCIZ15637 cell was determined by MTT assay.***p
    Figure 4 CIZ1 silencing induces the apoptosis of T24 and 5637 cells.
    (A and B) Flow cytometry analysis of apoptosis showed that CIZ1 knockdown induced T24 cell apoptosis. (A) Flow cytometry determination of apoptosis. (B) Quantification result of apoptosis. **p<0.01.
    (C and D) Flow cytometry determination of apoptosis showed that CIZ1 knockdown promoted the apoptosis of 5637 cells. (C) Flow cytometry examination of apoptosis. (D) Quantification result of apoptosis. **p<0.01.
