Evaluation of transcriptomic signature as a valuable tool to study drug-induced cholestasis in primary human hepatocytes.

Primary human hepatocyte (PHH) sandwich cultures from five different donors were daily exposed to cyclosporine A (CsA), ibuprofen (IBU), chlorpromazine (CPZ), amiodarone (AMI) and paracetamol (APAP) at their respective C (total) for short-term (1-3 days) and long-term treatment (14 days). Whole genome mRNA profiles (34,693 genes in total) were conducted using an Illumina microarray platform. The impact of compound treatments on gene signatures involved in liver differentiation, cholestasis and in bile acid homeostasis was evaluated.
