Abstract Background Heparanase (HPSE) is an endo-β-D-glucuronidase, which is found overexpressed in various human cancers. The purpose of our work was to investigate the possible role of HPSE and the involved signaling molecules in the development of papillary thyroid carcinoma. Methods In this study, the expression plasmid of HPSE and RNA interference with shRNA specific for HPSE were used to elucidate the effects of HPSE on proliferation, apoptosis, migration and invasion in papillary thyroid carcinoma cells of B-CPAP. The probable downstream signaling molecules of HPSE were also explored. Results The results showed that upregulation of HPSE significantly promoted cell proliferation, migration and invasion of B-CPAP cells, and interfered with cell apoptosis. On the contrary, knockdown of HPSE exhibited the opposite effects. Compared with the parental cells, HPSE silencing cells showed attenuated capabilities of proliferation, migration and invasion, yet the apoptotic rate of transfected cells was increased. The activations of various signaling molecules correlated with cell biological behavior were found to be regulated by HPSE upregulation or knockdown. Conclusions Our results suggested that HPSE probably contributed to the progression and metastasis of papillary thyroid carcinoma, which were associated with multiple signaling pathways. HPSE could be a potent molecular target for the therapeutic strategy of papillary thyroid carcinoma.

And Function

Given the crucial role of microRNAs in the cellular proliferation of various types of cancers, we aimed to analyze the expression and function of a cellular proliferation-associated miR-188-5p in papillary thyroid carcinoma (PTC). Here we demonstrate that miR-188-5p is downregulated in PTC tumor tissues compared with the associated noncancerous tissues. We also validate that the miR-188-5p overexpression suppressed the PTC cancer cell proliferation. In addition, fibroblast growth factor 5 (FGF5) is observed to be downregulated in the PTC tumor tissues compared with the associated noncancerous tissues. Subsequently, FGF5 is identified as the direct functional target of miR-188-5p. Moreover, the silencing of FGF5 was found to inhibit PTC cell proliferation, which is the same pattern as miR-188-5p overexpression. These results suggest that miR-188-5p-associated silencing of FGF5 inhibits tumor cell proliferation in PTC. It also highlights the importance of further evaluating miR-188-5p as a potential biomarker and therapy target in PTC.
