Fig. 7: Effects of FMT on the intestinal barrier in mice exposed to diquat.

a Schematic diagram of the FMT experiment. b Body weight during FMT. c FITC-dextran levels in the serum of mice. (n = 6). d, e The expression levels of tight junction proteins (ZO-1, occludin, claudin1) were measured by Western blot analysis (n = 3). f Jejunum morphology was observed by H&E staining (n = 4). g Goblet cells in the jejunum were observed by AB-PAS staining. h mRNA expression level of MUC2 in the jejunum (n = 6). i mRNA expression level of REG3G in the jejunum (n = 6). Data are expressed as the fold change versus the 0.3-Se group or the 0.3-Se + diquat group (set to 1). Data are represented as mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001.
