Abstract:
This study is to investigate the effects of cisplatin combined with heparanase inhibitor OGT2115 on proliferation, invasion and migration of human nasopharyngeal carcinoma cells CNE-2 and to provide a new target for the treatment of metastasis of nasopharyngeal carcinoma. MTT assay was used to detect the cell viability of CNE-2 after exposure to different concentrations of DDP (2, 4, 8, 16 and 32 micromol x L(-1)), different concentrations of OGT2115 (0.4, 0.8, 1.6, 3.2 and 6.4 micromol x L(-1)), and DDP combined with OGT2115. Transwell assay was applied to analyze the effects of drugs on invasion and migration of human nasopharyngeal carcinoma cells. Wound healing assay was performed to detect cell migration and heparanase activity was analyzed by ELISA. MTT results showed that DDP can inhibit the proliferation of CNE-2 cells in a time and concentration-dependent manner, with an IC50 of 24.03 micromol x L(-1) at 24 h (P < 0.05), low concentration of DDP has almost no inhibitory effect on cell invasion and migration. DDP combined with OGT2115 can significantly inhibit cell invasion and migration. Inhibition of heparanase can significantly enhance anti-invasion and anti-proliferation of DDP.
