The study investigated whether resveratrol significantly affects mucin gene expression, production and secretion from airway epithelial cells. Confluent NCI‐H292 cells were pretreated with resveratrol for 30 min and then stimulated with EGF (epidermal growth factor), PMA (phorbol 12‐myristate 13‐acetate) and TNF‐α (tumor necrosis factor‐α) for 24 h, respectively. The MUC5AC gene expression and mucin protein production were measured by RT‐PCR and ELISA. The effect of resveratrol on TNF‐α‐ or PMA‐induced activation of NF‐κB p65 was also examined. Confluent primary rat tracheal surface epithelial (RTSE) cells were pretreated with adenosine triphosphate (ATP) for 5 min and then treated for 30 min in the presence of resveratrol to assess the effect on mucin secretion using ELISA. The results were as follows: (1) resveratrol inhibited the expression of MUC5AC gene induced by EGF or PMA or TNF‐α from NCI‐H292 cells; (2) resveratrol also inhibited the production of MUC5AC mucin protein induced by the same inducers from NCI‐H292 cells; (3) resveratrol inhibited the activation of NF‐κB p65 by TNF‐α or PMA in NCI‐H292 cells; (4) resveratrol significantly decreased ATP‐induced mucin secretion from cultured RTSE cells. This result suggests that resveratrol can regulate mucin gene expression, production and secretion, by directly acting on airway epithelial cells. Copyright © 2011 John Wiley & Sons, Ltd.
