  1. PCLS were exposed for 24 hours to model toxicants for cholestasis (cyclosporin A (CsA)-A, chlorpromazine (CPZ)-B), necrosis (isoniazid (ISND)-C, paraquat (PQ)-D), and steatosis (amiodarone (A)-E, valproic acid (VA)-F). Q-PCR was used to measure mRNA expression relative to actin β of four potential biomarkers: Abcg5, Abcg8, Baat, and Klf15. FC stands for fold change (treatment vs. control). Q-PCR was performed for liver slices obtained from five biological replicates. Asterisk (*) indicates significantly different gene expression (P < 0.05) from controls according to Mann–Whitney-test (MW). NS stands for not significant.
