Project description:Drug-induced hepatotoxicity is still one of the main reasons for drug attrition; therefore, there is an urgent need for more predictive models to identify the toxic potential of new drug candidates. Here, transcriptomic data from short- and long-term cultured primary human hepatocytes exposed to four pharmaceuticals, namely ibuprofen, chlorpromazine, cyclosporine A and amiodarone was analysed.

Project description:we assessed characteristic molecular and proteomic signatures in rat liver treated with drugs (pyrazinamide, ranitidine, enalapril, carbamazepine, and chlorpromazine) that are known to cause DILI in humans. In the present study, we assessed the characteristic gene expression signature for DILI in a rat model. Rats were administered representative drugs that are already known to induce DILI in humans and transcriptomic changes in rat liver were analyzed. The representative drugs, which induce three types (hepatocellular, mixed, and cholestatic) of DILI, that were used in this study were pyrazinamide (PZA, 150~1500 mg/kg), ranitidine (RAN, 209.5~2095 mg/kg), enalapril (ENA, 148.65~1486.5 mg/kg), carbamazepine (CBZ, 97.85~978.5 mg/kg), and chlorpromazine (CPZ, 7.1~71 mg/kg).

Project description:Rapidly increasing number of man-made chemicals urges the development of reliable time- and cost-effective approaches for the carcinogen detection and identification. Considering this, the utility of high throughput microarray gene expression profiling for the identification of genotoxic and non-genotoxic carcinogens in vitro was investigated. Human terminally differentiated hepatic HepaRG cells were treated with model liver carcinogens, genotoxic carcinogen aflatoxin B1 (AFB1) and non-genotoxic carcinogen methapyrilene, at IC10 and IC25 concentrations for 72 hours, and transcriptomic profiles were determined. Treatment of HepaRG cells with IC10 and IC25 concentrations of AFB1 resulted in altered expression of 538 and 3033 genes (p-value ≤0.01 and fold change ≥2.0), respectively, and treatment of HepaRG cells with methapyrilene at the IC10 and IC25 concentrations altered the expression of 1255 and 1861 genes, respectively. Pathway analysis of transcriptomic signatures in HepaRG cells treated with minimally cytotoxic IC10 concentrations of AFB1 and methapyrilene demonstrated a strong enrichment in genes involved in key carcinogen-associated pathways, including receptor-mediated effects, detoxification response, cell death and apoptosis, cell proliferation and survival, oxidative stress and inflammation. Importantly, DNA damage and repair, cell cycle progression, and cell cycle checkpoint control pathways were uniquely activated in AFB1-treated HepaRG cells, whereas receptor-mediated signaling detoxification response pathway was predominantly altered in methapyrilene-treated HepaRG cells. In summary, high throughput microarray gene expression approach identifies specific carcinogen-exposure-associated transcriptomic responses and identifies affected molecular pathways, and categorize pathways associated with carcinogen exposure in a short-term in vitro test.

Project description:Although drug induced steatosis represents a mild type of hepatotoxicity, it can progress into more severe non-alcoholic steatohepatitis. Current models used for safety assessment in drug development and chemical risk assessment do not accurately predict steatosis in humans. Therefore, new models need to be developed to screen compounds for steatogenic properties. We have studied the usefulness of mouse precision-cut liver slices (PCLS) as an alternative to animal testing to gain more insight into the mechanisms involved in the steatogenesis. To this end, PCLS were incubated 24h with the model steatogenic compounds, amiodarone (AMI), valproic acid (VA), and tetracycline (TET). Transcriptome analysis using DNA microarrays was used to identify genes and processes affected by these compounds. AMI and VA upregulated lipid metabolism, whereas processes associated with extracellular matrix remodelling and inflammation were downregulated. TET downregulated mitochondrial functions, lipid metabolism, and fibrosis. From the transcriptomics data it was hypothesized that all 3 compounds affect peroxisome proliferator activated-receptor (PPAR) signalling. Application of PPAR reporter assays classified AMI and VA as PPARγ and triple PPARα/ (β/δ)/γ agonist, respectively, whereas TET had no effect on any of the PPARs. Some of the differentially expressed genes were considered as potential candidate biomarkers to identify PPAR agonists (i.e. AMI and VA) or compounds impairing mitochondrial functions (i.e. TET). Finally, comparison of our findings with publicly available transcriptomics data showed that a number of processes altered in the mouse PCLS was also affected in mouse livers and human primary hepatocytes exposed to known PPAR agonists. Thus mouse PCLS are a valuable model to identify mechanisms of action of compounds altering lipid metabolism. Two sets of candidate biomarkers could be used to screen compounds interfering with lipid metabolism by different mechanisms. Cholestatic compounds exposures Mouse precision cut liver slices (PCLS) were prepared from livers obtained from 5 different C57BL/6 male mice (24 weeks old). PCLS were cultured for 24 hours at 80% of oxygen; 5% CO2 and the remaining gas volume was filled up to 95% with N2. PCLS were exposed to model steatogenic, cholestatic, and necrotic compounds selected based on published reports. As steatogenic model compounds amiodarone (AMI), valproic acid (VA), and tetracycline (TET) were selected. As model cholestatic compounds cyclosporin A (CsA), chlorpromazine (CPZ), and ethinyl estradiol (EE) were applied. As necrotic compounds acetaminophen (APAP), isoniazid (ISND), and paraquat (PQ) were applied. To select a non-toxic dose eventually to be used for exposure experiments and subsequent gene expression profiling experiments, the following concentrations ranges were tested: AMI 0-100 μM, VA 0-500 μM, TET 0-100 μM , CsA 0-100 μM, CPZ 0-80 μM, EE 0-100 μM, PQ 0-10 μM, APAP 0-3000 μM and ISND 0-1000 μM. CsA, CPZ, AMI, PQ, EE were dissolved in DMSO, VA and TET were dissolved in ethanol (EtOH), and ISND was dissolved in PBS. The compounds were added to the culture medium at a final concentration of 0.1% vol/vol in an appropriate solvent (DMSO, EtOH, or PBS). Slices incubated with the solvents at 0.1% vol/vol served as controls. The viability of the slices was assessed by measuring the ATP content normalized on protein. Dose selection for the three steatogenic, cholestatic, and necrotic exposures were performed in 5 independent experiments with slices obtained from 5 mice. Concentrations that did not cause a decrease of the ATP level normalized on protein, compared to controls, were selected. For transcriptome analysis, PCLS were cultured at the same conditions as described above. The selected concentrations for steatogenic, cholestatic, and necrotic drugs were tested again in liver slices obtained from 5 different mice to re-confirm that the selected concentrations for the exposure experiments were not toxic. The concentrations used in the exposure experiments were for the steatogenic compounds: 50 μM for AMI, 200 μM for VA, and 40 μM for TET. For the cholestatic exposures 40 μM CsA, 20 μM CPZ, and 10 μM EE. For the necrotic compounds: 1000 μM APAP, 1000 μM ISND, and 5 μM PQ. Thereafter, RNA was extracted from three slices per each condition and after processing, the samples were hybridized on the HT Mouse Genome 430 PM array plate(s) using the Affymetrix GeneTitan system (CA, USA).

Project description:Amiodarone reversibly decreases sodium-iodide symporter mRNA expression at therapeutic concentrations and induces antioxidant responses at supraphysiological concentrations in cultured human thyroid follicles Amiodarone, a potent antiarrhythmic agent, is a highly active oxidant, exerting cytotoxic effects on thyrocytes at pharmacological concentrations. Patients receiving amiodarone usually remain euthyroid, but occasionally develop thyroid dysfunction, such as amiodarone-associated hypothyroidism or amiodarone-induced thyrotoxicosis. To elucidate the mechanism by which amiodarone elicits thyroid dysfunction, human thyroid follicles were cultured with TSH and amiodarone at therapeutic (1-2 microM) and pharmacological (10-20microM) concentrations, and the drug-induced effect on whole human gene expression was analyzed by cDNA microarray. Amiodarone at 1-2microM decreased the expression level of the sodium-iodide symporter (NIS) to nearly half, but did not affect genes participating in thyroid hormonogenesis (thyroid peroxidase, thyroglobulin, pendrin, NADPH oxidase). Higher concentrations (10-20 microM) decreased the expression of all these genes, accompanied by increased expression of antioxidant proteins such as heme oxygenase 1 and ferritin. When thyroid follicles obtained from a patient with Graves’ disease who had been treated with amiodarone for 2 months before thyroidectomy were cultured in amiodarone-free medium, TSH-induced thyroid function was intact, suggesting that amiodarone at a maintenance dose did not elicit any cytotoxic effect on thyrocytes. The ultrastructural features of cultured thyroid follicles were compatible with these in vitro findings. These in vitro and ex vivo findings suggest that patients taking maintenance doses of amiodarone usually remain euthyroid, probably due to escape from the Wolff-Chaikoff effect mediated by decreased expression of NIS mRNA. Furthermore, amiodarone is not cytotoxic for thyrocytes at therapeutic concentrations but elicits cytotoxicity through oxidant activity at supra-physiological concentrations.
