Combinations of the anthelmintics fenbendazole (FBZ) and triclabendazole (TCBZ) have shown enhanced efficacy against the liver fluke Fasciola hepatica. This study aimed to measuring the constitutive expression of CYP1A1, CYP1A2, FMO1 and FMO3, thought to be involved in the metabolism of those compounds, by using an absolute quantitative real time (RT)-PCR approach in bovine precision-cut liver slices (PCLS). It also aimed to characterize the effects of FBZ and TCBZ (alone and in combination) on the expression and activity of the aforementioned isozymes.Both FMO1 and FMO3 were equally represented in control PCLS, whereas CYP1A2 was expressed more than CYP1A1 (P
