STEE inhibits H2O2-induced proinflammatory gene expression in L929 cells. Cells were pretreated with different concentrations of STEE (0, 31.25, 62.5, and 125 μg/mL) for 24 h. The mRNA expression of COX-2, iNOS, TNF-α, and IL-6 in L929 cells was measured by qPCR at 1 h and 3 h after the end of exposure to 200 μM H2O2. Bars represent of four samples per group. The data were analyzed by one-way ANOVA followed by Tukey’s post hoc test. The means of treatments not sharing a common letter (A-C) are significantly different (comparison between treatments within each time point, ).
