Among the numerous mucin genes, MUC8 is regarded as one of the most important mucin genes which are related with upper airway disease such as a nasal polyp. 15-Deoxy-delta12,14-prostaglandin J2 (15d-PGJ2), the most recently discovered prostaglandin, has been known to have multiple cellular functions, including anti-inflammatory and cytoprotective effects. However, the effect of 15d-PGJ2 on mucin gene expression or mucin production has not yet been investigated. The purpose of this study was to determine the effect of 15d-PGJ2 on interleukin-1β (IL-1β)-induced MUC8 gene expression and mucin secretion in the cultured NCI-H292 cells and human nasal polyp epithelial cells. Subjects and Method:The MUC8 mRNA levels were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and MUC8 mucin levels were measured using an enzyme-linked immunosorbent assay (ELISA) in the cultured epithelial cells stimulated by IL-1β. 15d-PGJ2 was added 1 hour before stimulation. Results:15d-PGJ2 attenuated the IL-1β-induced MUC8 mRNA expression and mucin secretion with a dose-dependent pattern in both cultured NCI-H292 cells and human nasal polyp epithelial cells. Conclusion:These results suggest that 15d-PGJ2 may be considered as an effective agent for the control of airway mucus hypersecretion through the down-regulation of MUC8 gene.
