BackgroundThe bulb of Fritillaria thunbergii has been utilised as mucoregulators and expectorants for controlling the airway inflammatory diseases in folk medicine.Hypothesis/PurposeWe investigated whether verticine, ebeiedine and suchengbeisine isolated from the bulbs of Fritillaria thunbergii inhibit the gene expression and production of MUC5AC mucin from human airway epithelial cells.Study designConfluent NCI-H292 cells were pretreated with verticine, ebeiedine or suchengbeisine for 30 min and then stimulated with EGF, PMA or TNF-α for 24 h. The MUC5AC mucin gene expression was measured by RT-PCR. Production of MUC5AC mucin protein was measured by ELISA.Results(1) Verticine, ebeiedine or suchengbeisine inhibited the expression of MUC5AC mucin gene induced by EGF, PMA or TNF-α; (2) The production of MUC5AC mucin protein induced by EGF, PMA or TNF-α were also inhibited by treatment of verticine, ebeiedine or suchengbeisine.ConclusionThese results suggest that verticine, ebeiedine and suchengbeisine isolated from the bulbs of Fritillaria thunbergii inhibit the gene expression and production of MUC5AC mucin, by directly acting on airway epithelial cells, and the results are consistent with the traditional use of Fritillaria thunbergii as remedy for diverse inflammatory pulmonary diseases.
