a Representative western blot bands of ZO-1, Claudin-1, and Occludin in the colon. b Quantitative assessment of ZO-1, Claudin-1, and Occludin expression. c Representative images of ZO-1 immunostaining in the colon. Scale bars represent 250 µm. d Statistical result of ZO-1 density. e Levels of LPS and HMGB1 in mouse serum. n = 4. *p < 0.05, **p < 0.01, ****p < 0.0001.
