ABSTRACT
Cholangiocarcinoma (CCA) is a type of epithelial cancer with poor outcomes and late diagnosis. Accumulating evidence has demonstrated the promoting role of plasminogen activator, urokinase (PLAU) in several tumor types, while its function in CCA is largely unknown. The expression of PLAU in CCA was determined by data from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) database and further confirmed in human tissues using immunohistochemical (IHC) staining. Moreover, PLAU-silencing CCA cell models were constructed for subsequent functional assays in vitro and in vivo. PLAU expression in CCA was significantly higher than that in normal tissues. High PLAU expression was positively correlated with poor patients' survival. PLAU knockdown remarkably suppressed proliferation and migration of CCA cells, whereas enhanced apoptosis. Consistently, tumor growth in mice injected with PLAU-silencing CCA cells was also impaired. Furthermore, we revealed that the activation of NF-κB signaling was required for PLAU-induced malignant phenotypes of CCA cells. Inhibiting the high expression of PLAU in CCA may be a potential entry point for targeted therapy in CCA patient.
