Abstract: Objective  To investigate the expression of T-LAK cell-originated protein kinase/PDZ-binding-kinase (TOPK/PBK) in ovarian cancer and the effect of HI-TOPK-032, an inhibitor of TOPK/PBK, on ovarian cancer cells. Methods  The expression of TOPK/PBK in ovarian cancer tissue and normal samples were analyzed by gene expression profiling interactive analysis (GEPIA) software. The effect of HI-TOPK-032 on the proliferative activity of ovarian cancer cells was analyzed by methyl thiazolyl tetrazolium (MTT) assay and colony formation assay. The effect of HI-TOPK-032 was also assessed on subcutaneous ovarian tumor in nude mice. Results  The expression of TOPK/PBK in ovarian cancer was significantly higher than that in normal ovarian tissue (P<0.05). With the treatment of HI-TOPK-032, the expression of TOPK/PBK was inhibited, and the proliferation capacity of OVCAR3 and SKOV3 cells decreased (P<0.0001). The mass [(1.514±0.358)g vs (0.670±0.450)g] and volume [(0.418±0.171)cm3 vs (0.973±0.262)cm3] of subcutaneous tumors in the HI-TOPK-032 treatment group were significantly lower than that in the control group. Conclusions TOPK/PBK is highly expressed in ovarian cancer, contributing to the growth of ovarian cancer. HI-TOPK-032 exerts an inhibiting effect on the growth of ovarian cancer.
