Abstract: AIM: To investigate the effect of norepinephrine (NE) on proliferation, migration and invasion of human lung cancer cell line H460. METHODS: Human lung cancer cell line H460 were cultured in vitro and treated with NE, then CCK-8 mehod, scratch wound healing assay and transwell assay were applied to measure cell proliferation, migration and invasion. The expression of p38MAPK phosphorylation (Phos-p38) were examined by Western blotting. RESULTS: Compared with the control, 10 μmol/L NE significantly enhanced proliferation, migration and invasion of human lung cancer cell line H460, and elevated p38MAPK phosphorylation level (P<0.01). These effects were completely reversed by β-adrenergic receptor (β-AR) antagonist propranolol (PRO) or p38MAPK inhibitor U0126. CONCLUSION: NE could stimulate lung cancer cell proliferation, migration and invasion, its mechanism may be related with activation of P38MAPK pathway.

Key words: norepinephrine, lung cancer, proliferation, migration, invasion
