Fig. 6. The minimum dose of GGE03 required for exerting anti-inflammatory effects in Helicobacter pylori (H. pylori)-infected AGS cells. AGS cells were pretreated with GGE03 at indicated concentrations for 1 hour, followed by 3.5 hours co-culture with H. pylori (50 multiplicity of infection [MOI]). The effects of GGE03 on the mRNA expression of IL-8 (A), TNF-α (B), IL-6 (C), and iNOS (D) in AGS cells were determined by quantitative real-time PCR (qRT-PCR). 18S rRNA was used as an internal control for the expression of pro-inflammatory cytokines. Data are the mean ± SD. Statistical significance was analyzed by ANOVA. IL, interleukin; iNOS, inducible NOS. *P < 0.05 and ***P < 0.001 compared to control; ^#P < 0.05, ^##P < 0.01, and ^###P < 0.001 compared to the H. pylori group.
