Abstract

Objective. Heparanase (HPSE) is high-expressed in most malignant tumors including hepatocellular carcinoma (HCC) and promotes cancer cell invasion and migration. The aim of the study is to explore whether HPSE enhances adhesion in metastasis of HCC cells. Methods. HPSE expressions in human HCC cells were measured with real-time RT-PCR and Western blot analysis. Four recombinant miRNA vectors pcDNATM6.2-GW/EmGFP-miR-HPSE (pmiR-HPSE) were transfected into HCCLM3 cell. HPSE expression in transfected cell was measured. The cell invasion, migration, and adhesion abilities were detected, respectively. Results. Both HPSE mRNA and protein relative expression levels were higher in HepG2, BEL-7402, and HCCLM3 cells than those in normal hepatocyte (). HPSE showed highest expression level in HCCLM3 cell (). Transfection efficiencies of four miRNA vectors were 75%–85%. The recombinant vectors significantly decreased HPSE expression in transfected HCCLM3 cells (), and pmiR-HPSE-1 showed best interference effect (). pmiR-HPSE-1 significantly decreased the penetrated and migrating cells numbers and adherence rate of HCCLM3 cells (). Conclusion. HPSE is a potentiator of cell adhesion in metastasis of HCC.
