Altered gut microbiota in the b1/2-ARs KO chimera. (A) No significant difference in gut microbiota richness or diversity between the b1/2-ARs KO chimera and C57 control chimera. However, the Firmicutes to Bacteroidetes (F/B) ratio was significantly lower in the b1/2-ARs KO chimera compared to the C57 control chimera. (B) The decreased F/B ratio is attributed to the significant expansion of Bacteroidetes and contraction of Firmicutes. (C) Unweighted Principal coordinate analysis (PCoA) demonstrated a clear separation of red and blue clusters representing C57 and b1/2-ARs KO chimera groups, respectively. ** indicates P < 0.01.
