ABSTRACT
BACKGROUND:
Fenofibrate was reported to be beneficial for cholestasis in combination with ursodeoxycholic acid. However, its therapeutic action as single therapy for chronic cholestasis and the underlying mechanism are not known.METHODS:
In the present study, wild-type (WT) mice were administered a 0.05% ANIT diet to mimic chronic cholestatic liver injury. Mice were dosed fenofibrate 25 mg/kg twice every day for 10 days to investigate the therapeutic action of fenofibrate on chronic cholestatic liver injury. Ppara-null (KO) mice were used to explore PPARα's role in the therapeutic outcome.RESULTS:
Fenofibrate, administered at 25 mg/kg twice daily, substantially reversed ANIT-induced chronic cholestatic liver injury shown by biochemical and pathological end points. The modifications of bile acid metabolism were found to be adaptive responses. The JNK-AP1-CCL2/CXCL2 axis was activated in all the mice administered ANIT which developed chronic cholestatic liver injury. But it was substantially decreased by fenofibrate in WT mice rather than that in KO mice.CONCLUSIONS:
Low-dose fenofibrate reversed chronic cholestatic liver injury in mice. The therapeutic action was dependent on PPARα activation and occurred by inhibiting chemotaxis via the JNK-AP1-CCL2/CXCL2 signaling. These data provided an exciting basis for optimization of therapeutic fenofibrate regimen in the clinic. Additionally, they suggested anti-chemotaxis of low-dose fenofibrate in single therapy to treat cholestatic liver diseases.Palavras-chave
