STPE inhibits UVB-induced pro-inflammatory cytokine mRNA expression and secreted production in L929 cells. Cells were pretreated with different concentrations of STPE (0, 10, 20, and 40 μg/mL) for 24 h. a The mRNA expression of TNF-α, IL-6, and IL-1α in L929 cells was measured by qPCR at 24 h after the end of exposure to 10 mJ/cm2 UVB. b Cell culture supernatants were collected to measure cytokine production at 24 h after the UVB exposure (20 mJ/cm2). Bars represent means ± SEM of four samples per group. The data were analyzed by one-way ANOVA followed by LSD post-hoc test. Means with “*” differ significantly (p < 0.05)
