Effect of FXR deficiency on liver histopathology and steatosis in
LDLr-/- mice fed a high-fat diet. The LDLr-/- mice and
LDLr-/-/FXR-/- mice were fed either a control diet or a
high-fat diet for 5 months. Liver histology in each group of mice was
evaluated after hematoxylin and eosin staining (A, C, E, and G) of livers from
each group. Lipid accumulation in livers from each group of mice was evaluated
by Oil Red O staining (B, D, F, and H). Representative photomicrographs are
shown from LDLr-/- mice fed the control diet (A and B),
LDLr-/- mice fed the high-fat diet (C and D),
LDLr-/-/FXR-/- mice fed the control diet (E and F), and
LDLr-/-/FXR-/- mice fed the high-fat diet (G and H).
