Real-time PCR analyses of pro-inflammatory and anti-inflammatory cytokines in human corneal fibroblasts (HCFs) with or without angiogenin (ANG) treatment. a The increased relative mRNA levels of IL-1β, IL-6 and IL-8 by tumor necrosis factor-alpha (TNF-α) or lipopolysaccharide (LPS) were diminished by ANG treatment. b The relative mRNA levels of IL-4 and IL-10 were increased by ANG treatment. The experiments were repeated at least three times. Values represent the mean ± standard error. One-way ANOVA followed by Bonferroni’s post hoc analysis, *p < 0.05
