FIG. 4.
Serum and liver unconjugated bile acids in control and ANIT-treated wild-type, FXR-null, and PXR-null mice. Bile acids were quantified by UPLC-MS/MS as described in the “Materials and Methods” section. (A) Serum unconjugated bile acids are expressed as μg/ml ± SEM. (B) Liver unconjugated bile acids are expressed as μg/g ± SEM. “*” Represents significant differences (p < 0.05) compared to control mice (n = 5 animals). “#” Represents significant differences (p < 0.05) compared with ANIT-treated wild-type mice.
