Abstract

Objective:The aim of this study is to investigate the effect of gonadotropin releasing hormone (GnRH) on suppressing cell viability, apoptosis, migrationg and invationg of human nasopharyngeal carcinoma cells CNE2. Method:Nasopharyngeal carcinoma tissues and postnasal catarrh tissues were collected, the expression of GnRH positive cells and GnRH mRNA were detected by immunohistochemical staining and qRT-PCR. The human nasopharyngeal carcinoma CNE2 cells and immortalized nasopharyngeal epithelial cell line NP69 were cultured in vitro, and the expression of GnRH positive cells and GnRH mRNA were detected by immunohistochemical staining and qRT-PCR. The CNE2 cells were treated with GnRH with various concentrations 0 (Blank group), 10⁻², 10⁻¹, 10⁰ nmol/L. The effects of GnRH on the viability, apoptosis, migration and invasion of CNE2 cells were detected by cell Counting Kit (CCK-8), flow cytometry, wound healing assay and transwell chamber assay in vitro. Result:The expression of GnRH positive cells and GnRH mRNA in nasopharyngeal carcinoma tissues were markedly down regulated than postnasal catarrh tissues (P<0.05). The expression of GnRH positive cells and GnRH mRNA in CNE2 cells were markedly down regulated than NP69 cells (P<0....Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
