Gonadotropin‑releasing hormone inhibits the proliferation and motility of nasopharyngeal carcinoma cells.

Gonadotropin‑releasing hormone (GnRH), or its analogues have been demonstrated to exhibit anti‑proliferative effects on tumour cells in ovarian, endometrial and breast cancer through GnRH‑receptors (GnRH‑R). However, the role of GnRH in nasopharyngeal carcinoma (NPC) remains to be elucidated. In order to investigate the effects of GnRH in NPC, the present study examined the expression of the GnRH‑R transcript in NPC and investigated the phenotypic changes in HK1 cells, a recurrent NPC‑derived cell line, upon receiving GnRH treatment.
