Genes were measured using RT q-PCR, normalized to β-actin mRNA levels, and graphed as relative mRNA ± 1 SD. An asterisk denotes a significant difference from WT (P < 0.05). (A) Relative mRNA of hepatic genes involved in classic, alternative, and minor BA synthetic pathways. (B) Relative mRNA of hepatic genes for BA conjugation. (C) Relative mRNA of hepatic FXR, Shp, Fgfr4, Ntcp, and Bsep. (D) Relative mRNA of ileal genes involved in BA regulation and transport.
