Abstract

Heparanase (HPSE) and vascular endothelial growth factor C (VEGF-C) are important cytokines that promote metastasis and angiogenesis in numerous malignant neoplasms, however, their association remains unclear in pancreatic ductal cell adenocarcinoma (PDAC). The present study aimed to investigate whether HPSE has a positive correlation with VEGF‑C expression and to uncover the role it plays in the in vitro invasion of BxPC‑3 cells (a pancreatic carcinoma cell line), and to analyze the value of joint detection of HPSE and VEGF‑C for PDAC patients. A recombinant plasmid, GV230/HPSE was constructed and BxPC‑3 cells were transiently transfected with GV230/HPSE or siRNA against HPSE. The expression levels of HPSE and VEGF‑C were compared using reverse transcription quantitative PCR (RT‑qPCR) and immunoblotting. The metastatic potential of treated BxPC‑3 cells was evaluated using a Transwell® invasion assay. The relative mRNA levels of HPSE and VEGF‑C in 34 PDAC specimens were assessed by RT‑qPCR. The results of the RT‑qPCR demonstrated a 10.7‑ and 3.24‑fold elevation (P<0.01) of HPSE mRNA and VEGF‑C mRNA, respectively, in GV230/HPSE group, whereas the HPSE siRNA group were downregulated for these mRNAs (‑2.45‑fold, P<0.01; ‑1.84‑fold, P<0.01). The same pattern for protein expression was detected using immunoblot assays. In Transwell® invasion assays 138±5 cells in GV230 /HPSE group and 53±4 cells in siRNA group migrated through the Matrigel®. A negative correlation between the mRNA levels of HPSE and VEGF‑C in PDAC specimens and the prognosis factors of the postoperative patients was identified. Spearman rank correlation analysis indicated a positive correlation between HPSE and VEGF‑C in PDAC (r=0.812, P<0.01). HPSE regulates the expression of VEGF‑C and facilitates invasion of BxPC‑3 in vitro. Joint detection of HPSE and VEGF‑C may therefore be clinically useful in determining the prognosis of pancreatic cancer patients.
