Abstract: Objective To investigate the effects of norepinephrine(NE) on thebiological behavior of human pharyngeal squamous cell carcinoma cell line FaDu.MethodsMTT assay was used to evaluate the influence of NEontheproliferation of tumor cells. Transwellinvasion assay was used to evaluate theinfluence of NE on theinvasion of tumor cells.The effects of NE on themigrationof tumor cells wasmeasuredby Transwellmigration assayand wound-healing assay.Additionally, theeffects of the β-adrenergic antagonist propranolol on the NE-induced proliferation, invasion and migrationof tumor cellswere measured.Results10μmol/LNE promotedtheproliferation, invasion and migration of tumor cells significantly(P<0.001). However,pretreatment with 1μmol/L propranolol effectivelyinhibitedthe NE-induced proliferation, invasion and migration(P<0.001). ConclusionNEpromotestheproliferation, invasion and migration of human pharyngeal squamous cell carcinoma cells.These effectscan be suppressed by propranolol.

Key words: human pharyngeal squamous cell carcinoma cell line FaDu, norepinephrine, propranolol, proliferation, invasion, migration
