From: Oxidative stress enhances the expression of IL-33 in human airway epithelial cells
Effect of H2O2 on a synthetic viral dsRNA analogue, poly (I:C)-potentiated IL-33 expression. a NCI-H292 cells were treated with H2O2 or vehicle 30 min prior to the treatment with poly (I:C). After 4 h, whole cells were harvested and assayed for the IL-33 gene expression. b Effect of NAC on H2O2-augmented IL-33 expression in poly (I:C)-treated cells. Cells were added with NAC before H2O2 treatment, and then treated with poly (I:C). Values are the mean ± SEM (n = 3 - 4). ***p < 0.001 compared with the values of vehicle-treated control. †††p < 0.001 compared with the values of poly (I:C)-treated control
