Fig 4. GF mice transplanted with fecal microbiota from colitis mice displayed decreased levels of SCFAs and their receptors.

The fecal concentrations of (A) total SCFAs, (B) 3 major SCFAs, and (C) 3 minor SCFAs. (B) The mRNA expressions of SCFA receptors in the liver. Data are presented as the mean ± SD of each group (n = 5–7). Student’s two-tailed t-test was used for analysis difference between FMT-control and FMT-colitis (*p < 0.05, **p < 0.01, and ***p < 0.001).
