EGV-4T/TNFα-1, EGV-4T/IL6-1, EGV-4T/IL33v1-6, and EGV-4T/IL33v5-6 cells were stimulated with LPS at indicated concentrations for 6 h. Luciferase activity was measured to determine the promoter activity of pro-inflammatory cytokine genes. Relative activity is shown as a ratio to luciferase activity of untreated control cells. Each value represents the mean ± SD (n = 6). *p < 0.05, **p < 0.01 versus untreated control.
