Catechins and Sialic Acid Attenuate Helicobacter pylori-Triggered Epithelial Caspase-1 Activity and Eradicate Helicobacter pylori Infection

Figure 2

Effects of catechins (CAs) and/or sialic acid (SA) on IL-1β expression in AGS cells at 4 h after H. pylori (HP) infection. Upper panel, a representative western blot; lower panel, the fold change of the IL-1β levels relative to the expression in the untreated uninfected control, which was set at 1.0. Each column with a vertical line represents mean ± SEM (𝑛=3). ^∗𝑃<0.05, compared to the untreated uninfected control; ^#𝑃<0.05, compared to H. pylori infection alone.
