Lactobacillus acidophilus Suppresses Colitis-Associated Activation of the IL-23/Th17 Axis

Figure 4

Treatment with Lactobacillus acidophilus reduced TGFβ1 expression in colitis. The mRNA (a) and protein (b) levels of TGFβ1 expression were examined by RT-PCR and Western blotting, respectively, in the colonic tissues of normal control mice group (normal) and DSS-induced mice groups, including L. acidophilus-treated C4–C8 groups, prednisone acetate treated positive control (Pred), and nontreated (Non) and vehicle (Veh) treated control groups. Representative electrophoresis images are shown on the left, and bar graphs presenting mean ± SD () values are shown on the right. A plotted trendline chart shows TGFβ1 expression in each group at both mRNA and protein levels (c). versus Non, versus Veh, versus Pred, and versus normal.
