Objective To study the effect of NOX4 on IL-6 expression in non-small cell lung cancer( NSCLC)A549 cells and identify the roles of NOX4 and IL-6 on A549 cell invasion. Methods The stable cell line expressing NOX4 was generated by transfection of p CMV-NOX4 into A549 cells,and NOX4 expression was determined by RT-PCR and western blotting. The expression of IL-6 was evaluated by ELISA. The cell invasive ability was observed by the transwell test. The level of phosphorylated Akt was identified by western blott...
