In previous studies Sulf2 has been evidenced to play an important role in tumor progression through editing sulfate moieties on heparan sulfate proteoglycans (HSPGs) and modulating heparin binding growth factors. However, the role of Sulf2 in breast cancer progression is still poorly understood. In the present study, we hypothesized that Sulf2 promoted breast cancer progression. Two different breast cancer cell lines, MCF-7 and MDA-MB-231, were chosen for this study because of high and low Sulf2 expression levels. We also altered their Sulf2 expression by establishing Sulf2 knockdown and overexpressing breast cancer cell lines MCF-7 shSulf2 and MDA-MB-231 Sulf2. To evaluate the functions of Sulf2, cell proliferation, apoptosis, cell cycle, invasion, mobility and adhesion of these cell lines were measured in vitro, and xenograft formation, invasion and metastasis ability were examined in vivo. Furthermore, expression of related genes were screened and were certified in these cell lines. We found that Sulf2 increased breast cancer proliferation, invasion, mobility and adhesion both in vitro and in vivo. Sulf2 also decreased cisplatin inducing breast cancer apoptosis without affecting the cell cycle. Sulf2 upregulated c-fos induced growth factor (FIGF) and nuclear receptor subfamily 4 group A member 3 (NR4A3) expression and downregulated the cluster of differentiation 82 (CD82) and platelet-derived growth factor C (PDGFC) expression in breast cancer. Our data confirmed that Sulf2 promoted breast cancer progression and regulated the expression of tumor-related genes in breast cancer.
