Project description:Cyclosporine A (CsA), is an endecapeptide with strong immunosuppressant activities and has contributed significantly towards clinical progress in organ transplantation. Furthermore, it has various toxic effects in the kidney and especially in the liver where it may induce cholestasis. The CsA drug-induced cholestasis (DIC) pathway includes important genes involved in the uptake, synthesis, conjugation and secretion of bile acids, which can be verified also in hepatic models in vitro. However, whether changes in CsA-induced cholestasis pathway induced in vitro are persistent thus presenting important biomarkers for repeated dose toxicity, has not yet been investigated. We therefore performed multiple -omics analyses, including whole genome analysis of DNA methylation, gene expression and microRNA expression in primary human hepatocytes (PHH) cultured in sandwich configuration, during and after terminating CsA treatment. For this, cells were exposed to a non-cytotoxic dose of 30 µM CsA daily for 3 and 5 days. To investigate the persistence of induced changes upon terminating the CsA exposure of 5 days, a subset of PHH was subjected to a washout period (WO-period) of three days. DNA methylation (using NimbleGen 2.1 deluxe promoter arrays), transcriptomic (using Affymetrix Human Genome U133 Plus 2.0 arrays) and microRNA (using Agilent Sureprint G3 Unrestricted Human miRNA V16 8 × 60 K microarrays) analyses were performed on days 3, 5 and 8. Identification of differentially methylated genes (DMGs), differentially expressed genes (DEGs), and differentially expressed microRNAs (DE-miRs) was performed using several R packages. DMGs, DEGs and DE-miRs were found after CsA treatment of PHH for 3 and 5 days as well after the WO-period. Interestingly, 828 persistent DEGs and 6 persistent DE-miRs, but no persistent DMGs, were found after the WO-period. These persistent DEGs and DE-miRs showed concordance for 22 genes (13 genes upregulated in gene expression and downregulated in microRNA expression; 9 genes downregulated in gene expression and upregulated in microRNA expression). Some of the persistent transcriptomic changes as well as DE-miRs could be successfully mapped onto the DIC pathway, while epigenetic changes not. Furthermore, 29 persistent DEGs in vitro showed changes in the same direction as observed in livers from cholestasis patients. None of those 29 DEGs were present in the DIC pathway or cholestasis adverse outcome pathway. We have for the first time demonstrated a persistent impact of gene expression and microRNA expression related to DIC after repeated dose administration of CsA in vitro.

Project description:To elucidate the gene profile of anti-fibroproliferative effects of cyclosporine, we added TGF-b and/or CsA to MRC5 (fetal human lung fibroblast) cell line. After 24 hours serum starvation, fibroblasts were treated with 3 ng/ml TGF-β1 and were treated with or without 2μg/ml Cyclosporine and effects were examined at 48 hours after treatment. Expression of three genes (IGFBP3, ID1 and PPARG) from this signature was quantified in the same RNA samples by real-time PCR. TGF-β and cyclosporine induced gene expression data was measured in MRC5 (fetal human fibroblast cell line) at 48h after treatments. The dose of TGF-β was 3 ng/ml and cyclosporine was 2 μg/ml. The comparison was done between four groups (control, TGF-β, cyclosporine and TGF-β plus cyclosporine).Three independent experiments were performed at each treatments using different samples for each experiment.

Project description:Cholestasis is characterized by disrupted bile flow from the liver to the small intestine. Although etiologically different cholestasis display similar symptoms, diverse factors can contribute to the progression of the disease and determines the appropriate therapeutic option. Therefore, stratifying cholestatic patients is essential for the development of tailor-made treatment strategies. Here, we have analyzed the liver proteome from cholestatic patients of different etiology. 7,161 proteins were identified and quantified, of which 263 were differentially expressed between control and cholestasis groups. These differential proteins point to deregulated cellular processes that explain part of the molecular framework of cholestasis progression. However, the clustering of different cholestasis types was limited. Therefore, a machine learning pipeline was designed to identify a panel of 20 differential proteins that segregate different cholestasis groups with high accuracy and sensitivity. In summary, proteomics combined with machine learning algorithms provides valuable insights into the molecular mechanisms of cholestasis progression and a panel of proteins to discriminate across different types of cholestasis. This strategy may prove useful to develop precision medicine approaches for patient care.
