FIGURE 2.

The effects of sodium propionate on intestinal barrier function in DSS-induced mice. The FITC-dextran levels in serum were determined (A). n = 10 per group. The expression of tight junction and associated protein ZO-1, E-cadherin and occluding in colonic tissues was determined by immunoblotting (B–E). β-actin was used as the protein loading control. n = 4 per group. Representative blots of three independent experiments are shown. Data are presented as mean ± SD. ^∗P < 0.05, ^∗∗P < 0.01 vs. control group; ^#P < 0.05, ^##P < 0.01 vs. DSS group.
