Figure 4. Transcriptional levels of genes important for components of gut barrier function, including regulatory genes for intestinal (A) permeability and (B) LPS response, and (C) mucin production and (D) inflammation in the colonic and ileal tissue of mice fed an LFD or HFD with or without GPs. Statistical significance of parametric data was determined via two-way ANOVA, followed by Holm-Sidak's multiple-comparisons test. Different letters denote statistical significance. p < 0.05 was considered significant. Each symbol denotes a single animal.
