Abstract

As a notable feature of malignant tumors, invasion and metastasis are important events in the process of tumor progression. Amiloride, a synthetic inhibitor of urokinase plasminogen activator (uPA), is involved in these events. To evaluate the therapeutic value of amiloride in cervical cancer, HeLa cells were used as in vitro cellular models. The migration and invasion abilities of HeLa cells, in addition to the mRNA expression of matriptase, uPA, uPA receptor and 72 kDa type IV collagenase (MMP‑2), were detected using scratch assays, Transwell chamber assays and reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR). The results of RT‑qPCR demonstrated that the mRNA expression of uPA and MMP‑2 in HeLa cells was downregulated significantly in a dose‑dependent manner when incubated with various concentrations of amiloride for 24 h. The migration distance of HeLa cells was significantly shorter at 6, 12 and 24 h following incubation with amiloride (P<0.01), and there was a positive correlation between cell migratory ability and cellular uPA protein expression level (r=0.955, P<0.01). The number of HeLa cells that penetrated the Matrigel following incubation for 24 h with different concentrations of amiloride decreased significantly compared with the control group, indicating that cell invasiveness was positively correlated with the protein expression level of uPA in the cells (r=0.993, P<0.01). The present study demonstrated that amiloride was able to specifically inhibit the mRNA expression levels of uPA in HeLa cells, and sequentially downregulate the mRNA expression of downstream MMP‑2 in the uPA system, thereby suppressing the migratory and invasive ability of HeLa cells. Therefore, amiloride may be a promising therapeutic target for the treatment of cervical cancer.
