Dietary Bioactive Peptide Alanyl-Glutamine Attenuates Dextran Sodium Sulfate-Induced Colitis by Modulating Gut Microbiota

Figure 5

Supplementations of Gln and Ala-Gln altered the colon microbiota in colitic mice. (a, b) Alpha diversity was estimated by using Shannon and Simpson indices. (c, d) Principal component analysis (PCA) plot and partial least squares discriminant analysis (PLS-DA) analysis of gut microbiota. (e) Venn graph for OTUs. (f) LEfSe taxonomic cladogram. Different colors represent biomarker taxon enrichment of control (green), DSS (blue), Gln (purple), and Ala-Gln (red) groups. (g) Linear discriminant analysis (LDA) score (log10) of the different bacterial abundances. Results were shown as (). , .
