Expression of genes implicated in BA homeostasis. A) Hepatic and ileal gene expression in WD-fed WT and WD-fed FXR KO mice. B) Expression of BA homeostasis genes in the liver and ileum of CD, WD, and WD+EGCG-fed WT mice. C) Western blot analysis of indicated protein levels in the liver and ileum. D) Quantitative results of the indicated proteins, which were normalized to the corresponding β-Actin level (n = 3–4/group). Data are means ± sd. *P < 0.05, **P < 0.01, ***P < 0.001 (1-way ANOVA with Tukey’s correction).
