- Abstract
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.)
