- Abstract
<bold>Objective: </bold>The study aimed to investigate cyclin-dependent kinase 14 (CDK14) and its co-function with Wnt signaling pathway on cell proliferation, migration and invasion in ovarian cancer.<bold>Methods: </bold>CDK14 expressions were detected by quantitative real-time polymerase chain reaction. The expressions c-Myc, cyclinD1, PFTK1, ki67 and OGT were examined by Western blot. MTT assay was applied to observe cell proliferation after transfection of pEGFP-N1/CDK14-siRNA and pEGFP-N1 into SKOV3 cells, and scratch test and Transwell assay to observe invasion and migration ability. Transfected tumor model in nude mice was established.<bold>Results: </bold>CDK14 was upregulated in the ovarian cancer tissues and cell lines (both p < 0.05). Expressions of downstream molecules in Wnt signaling pathway as well as the proliferation, invasion and migration ability of the SKOV3 cells were reduced when CDK14 was inhibited (all p < 0.05). The expression of β-catenin in the nucleus was also decreased when CDK14 was inhibited (p < 0.05). In the transfected tumor model of nude mice, the results showed, compared with the pEGFP-N1 group and blank control group, that the expressions of c-Myc, cyclinD1, PFTK1, ki67 and OGT in the pEGFP-N1/CDK14-siRNA group in the transplantation tumor tissues decreased significantly (all p < 0.05).<bold>Conclusion: </bold>CDK14 suppression-mediated Wnt signaling pathway can inhibit cell proliferation, invasion and migration in ovarian cancer.
