The lack of FXR altered gut microbiota composition (N = 5 per group). (A) Weighted Unifrac analysis of beta diversity. (B) Shannon analysis of microbiome diversity. (C) Phylum Fimicutes in LFD-fed mice. WT-LFD vs. FXRko, p = 0.01. (D) Phylum Bacteroidetes in LFD-fed mice. WT-LFD vs. FXRko-LFD, p = 0.0004. (E) Phylum Proteobacteria in LFD-fed mice. WT-LFD vs. FXRko-LFD, p = 0.002. (F) Phylum Fimicutes in HFD-fed mice. WT-HFD vs. FXRko-HFD, p = 0.1. (G) Phylum Bacteroidetes in HFD-fed mice. WT-HFD vs. FXRko-HFD, p = 0.25. (H) Phylum Proteobacteria in HFD-fed mice. WT-HFD vs. FXRko-HFD, p = 6.5E-07. (I) Phylum Fimicutes in BD-treated mice. WT-BD vs. FXRko-BD, p = 0.05. (J) Phylum Bacteroidetes in BD-treated mice. WT-BD vs. FXRko-BD, p = 0.2. (K) Phylum Proteobacteria in BD-treated mice. WT-BD vs. FXRko-BD, p = 0.004.
