Modulation of BA metabolism does not affect glucose homeostasis in FXR−/−ob/ob mice. FXR+/+ob/ob and FXR−/−ob/ob mice (10 weeks old) were administered 2% colesevelam mixed in the diet or plain diet for 3 weeks (n = 13/group) (FXR+/+ob/ob control, white bars or circles; FXR+/+ob/ob treated, horizontally hatched bars or white squares; FXR−/−ob/ob control, black bars or circles; FXR−/−ob/ob treated, diagonally hatched bars or black squares). A: TGR5 target gene expression was measured by QPCR in BAT of 20-week-old mice (n = 9 to 10/group). B: Plasma BA were measured after 9 days of treatment. C: Body weight was monitored weekly during the treatment period. Significance of the overall effect of treatment (P < 0.0001) and age (P = 0.0002) was calculated by two-way ANOVA. D: Fasting blood glucose was determined weekly during the treatment period. Blood glucose excursion (E) and integrated AUC (F) after administration of an intraperitoneal glucose bolus (1 g/kg glucose) were measured at the end of the treatment period. G: Plasma insulin was measured at the end of the treatment period. Values are means ± SEM. Differences between treatment groups over time were analyzed by two-way ANOVA and Bonferroni post hoc test; differences between genotypes or treatment groups were calculated by Mann-Whitney test. *Compares genotypes of the same treatment group; $compares treatment groups of the same genotype (* or $P < 0.05, ** or $$P < 0.01, ***P < 0.001).
