Summary: | The present study aimed to investigate expression of [beta]2-adrenergic receptor (AR), the effect of the stress-related neurotransmitter norepinephrine (NE) on cell viability, proliferation and the therapeutic effect of propranolol, which is a typical [beta]-blocker in various type of head and neck cancers for the first time. The [beta]2-AR expression was investigated using immunohistochemistry and an immunoreactive scoring (IRS) system in 57 different head and neck cancer specimens, and reverse transcriptase-polymerase chain reaction and western blotting in four head and neck cancer cell lines (HNCCLs). Cell viability and proliferation assays were performed using 0, 1, 5 and 10 [micro]M of NE and 1 [micro]M of propranolol in four HNCCLs. The expression of [beta]2-AR was positive in the majority of head and neck cancer tissues (55/57, 96.5%); however, it was signifcantly higher in oral cavity cancer than in pharyngeal cancer (median IRS: 9 vs. 3; P |
