UDCA alters key determinants of hepatic bile acid and cholesterol homeostasis. (A) mRNA analysis of bile acid biosynthesis markers. Controls: n = 18; UDCA: n = 19. (B) Representative Western blots of CYP7A1, FXR and densitometry (all samples) of protein levels relative to β-actin. Controls: n = 7; UDCA: n = 6. (C) ABCD-assay indicating FXR activity. Controls: n = 7; UDCA: n = 6. (D) mRNA analysis of cholesterol biosynthesis markers. Controls: n = 18; UDCA: n = 19. (E) Representative Western blots of HMGCR, phosphorylation status of HMGCR (HMGCRp), LDLR and densitometry (all samples). Controls: n = 7; UDCA: n = 6. Mean values ± SD are expressed for all data. ∗p ⩽0.05, ∗∗p ⩽0.01 vs. control group.
