    • Abstract:
      BACKGROUND: Targeting protein for Xenopus kinesin-like protein 2 (TPX2) is a microtubule-associated proteinrequired for mitosis and spindle assembly. It has been revealed that TPX2 is overexpressedin various human cancers and promotes cancer progression. METHODS: The expression of TPX2 was examined in ovarian cancer (OC) tissues and by Western blotting, quantitative real-time reverse transcription PCR (qRT-PCR) and immunohistochemistry. The effects of TPX2 on proliferation and migration of two OC cell lines SKOV3and RMG1 were analyzed using the methylthiazol tetrazolium (MTT) assay, flow cytometry and transwell assay. The mechanisms underlying the effects of TPX2 on OC cells were explored by qRT-PCR and Western blot. RESULTS: In this study, we found that TPX2 was upregulated in OC tissues. We observed knockdown of TPX2 inhibited the expression of Polo-like kinase 1 (PLK1), which has an important role in the regulation of M phase of the cell cycle, and the activity of Cdc2, induced cell arrested at the G2/M phase and decreased proliferation. Moreover, our data revealed that the levels of PLK1, β -catenin, MMP7 and MMP9 were inhibited following TPX2 knockdown, leading to decrease of cell migration. Finally, we showed that the restoration of PLK1 expression attenuated the anti-proliferation and anti-migration effects of TPX2 knockdown in OC cells. CONCLUSIONS: TPX2 promotes the proliferation and migration of human OC cells by regulating PLK1 expression. [ABSTRACT FROM AUTHOR]
