Effect of Glycyrrhizin uralensis flavonoids on phorbol 12-myristate 13-acetate (PMA)-induced mucin 5AC (MUC5AC) protein secretion. Serum-deprived NCI-H292 cells were pretreated with G. uralensis (500 or 100 µg/mL) or the G. uralensis flavonoids liquiritigenin (LQ), isoliquiritigenin (ILQ), and 7,4′-dihydroxyflavone (7,4′-DHF; 10 µM), or dexamethasone (Dex; 10 µM) for 30 min and then stimulated with PMA (10 ng/mL) for 24 h. MUC5AC protein secretion in supernatants was measured by ELISA. Each represents a mean ± SD of three independent experiments in comparison with that of control set at 1. ** p < 0.01, versus PMA stimulation, nontreatment group; # p < 0.05, versus PMA stimulation, 7,4′-DHF treatment group.
