PPL expression in Fxr −/− and CA-fed cholestasis model mice. (A) Hepatic Ppl mRNA expression levels in Fxr +/+ and Fxr −/−mice. Seven or 8 mice per group were examined. Circles and rectangles correspond to individual animals. Horizontal bars represent averages. (B) Hepatic Ppl and Cyp7a1 mRNA expression levels in wild-type mice fed cholic acid (CA) for 7 days at the indicated doses. Five to 9 mice per group were examined. The immunoblot for PPL is also shown. Equal amounts of protein from 5 mice were combined in each group for western blotting. The immunoblot for GAPDH was used as the loading control. (C) Ppl mRNA expression in various tissues following CA feeding for 7 days. Bars for each tissue are grayscaled as indicated (darkened from left to right, tongue to skin). Bars for the liver are flagged with a number sign (#). Four samples per group were examined. (D) Hepatic mRNA expression of plakins, cell junction proteins, and intermediate filaments in wild-type mice fed CA for 7 days. Five to 9 mice per group were examined. mRNA expression levels are represented as values normalized to Gapdh. The average values in Fxr +/+ and control diet-fed mice are set as 1.0. Values represent mean ± SD.
