KHK−/− and WT mice were fed 20% fructose for 3 wk with (KHK-F + AB or WT-F + AB) or without (KHK-F or WT-F) AB treatment (n = 5–7/group). The mRNA expression levels of gut peptides were measured in WT-F, KHK-F, WT-F + AB, and KHK-F + AB mice in the ileum (A), the cecum (B), and the proximal colon (C). Data were normalized to levels in WT-F. All values are means ± sem. Means were compared by 1-way ANOVA followed by Tukey’s post hoc test. *P < 0.05, **P < 0.01, ***P < 0.001.
