Abstract
- BACKGROUND AND OBJECTIVES
Naringenin and delphinidin are types of anthocyanidin, which are flavonoids and thus have anti-inflammatory property. Moderate consumption of natural dietary naringenin and delphinidin is believed to do anti-inflammatory action, but the action mechanism is unclear. Therefore, this study aimed to investigate the effects of naringenin and delphinidin on interleukin-1beta (IL-1beta)- and lipopolysaccharide (LPS)-induced MUC5AC and MUC5B expressions in airway epithelial cells. MATERIALS AND METHOD: In NCI-H292 cells and cultured nasal polyp epithelial cells, the effects of naringenin and delphinidin on IL-1beta- and LPS-induced MUC5AC and MUC5B expressions were analyzed by real-time polymerase chain reaction and enzyme-linked immunosorbent assay.
RESULTS
Delphinidin attenuated IL-1beta- and LPS-induced MUC5AC and MUC5B mRNA and glycoprotein expression in a dose-dependent pattern in NCI-H292 cells and in cultured nasal polyp epithelial cells. Naringenin partially attenuated IL-1beta- and LPS-induced MUC5AC and MUC5B mRNA and glycoprotein expression at a high dose.
CONCLUSION
These results suggest that delphinidin attenuates MUC5AC and MUC5B expressions in the airway epithelial cells. Between anthocyanidin and delphinidin, delphinidin exhibits greater potential as an ideal therapeutic agent for the control of mucus-hypersecretion in the treatment of airway inflammatory diseases.
