Effects of dietary xylanase on the expression of MUC2 in the gut of Nile tilapia. A Heatmap of differentially expressed genes of gut barrier in the comparison between SM vs. SMC (n = 4), B Gene expression level of mucin2 (muc2) (n = 6), C Immunohistochemical of MUC2 in gut of Nile tilapia (n = 3), D Western blot analysis of intestinal MUC2 (n = 3). Data was expressed as mean ± SEM. SM, fish fed with soybean diet; SMC, fish fed with soybean diet supplemented with 3,000 U/kg xylanase. The significant differences between two group were presented at P < 0.01 (**)
