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.

Project description:AAmiodarone is an antiarrhythmic drug and representatively induce pulmonary phospholipidosis. Amiodarone-induced toxicity has been a serious unpredictable side effect of the treatment and an important clinical problem. Possible causes include allergic, cytotoxic or immunologic reactions to this agent. We examined the consequences of the mechanism of amiodarone-induced pulmonary toxicity gene expression in BEAS-2B cells, huma bronchial cell line, by microarray. The expression of these genes are potential biomarker of amiodarone-induced pulmonary toxicity. Also, We provide a clue about mechanism of pulmonary toxic action by these clinical chemotherapeutic agents.

Project description:Interstitial lung disease (ILD) is a group of respiratory disorders characterized by chronic inflammation and fibrosis of the pulmonary interstitial tissues. Although the etiology of ILD remains unclear, some drug treatments are one of the primary causes of ILD. In the present study, we analyzed FDA Adverse Event Reporting System and JMDC insurance claims to find a coexisting drug that reduced the incidence of ILD associated with use of an anti-arrhythmic agent, amiodarone, and found that the thrombin inhibitor dabigatran prevented the amiodarone-induced ILD in both clinical datasets. In an experimental validation of the hypothesis, a long-term, oral treatment of mice with amiodarone caused a gradual decrease in the body weight caused by respiratory insufficiency. In the lung of amiodarone-treated mice, infiltration of macrophages and interstitial thickening were observed in parallel with a delayed upregulation of platelet-derived growth factor receptor α gene. In contrast, co-treatment with dabigatran significantly attenuated these amiodarone-induced changes representing ILD. These results suggest that dabigatran is effective in preventing the drug-induced ILD. This combinatorial approach of drug repositioning based on clinical big data will pave the way for finding a new treatment with high clinical predictability and a well-defined molecular mechanism.

Project description:Toxicogenomics (tgx) is used as a tool to identify mechanisms and markers of steatosis in C57BL/6 mice treated by oral gavage using amiodarone (AMD), valproic acid (VPA), and tetracycline (TET). Critical doses for tgx analysis were derived from a 25 day dose range finding study. For tgx analysis, livers of mice were collected after 1, 4, and 11 days of repeated treatment with 6.7, 20, and 60 mg/kg bw for AMD; 125, 250, and 500 mg/kg bw for VPA; and 14.8, 44, and 133 mg/kg bw for TET.

Also, We provide a clue about mechanism of pulmonary toxic action by these clinical chemotherapeutic agents. BEAS-2B cells were seeded and after incubation for 24 h at 37C, the cells were treated with 29.388 μM(IC20) amiodarone for 48 h. And after total RNA isolation, gene expression analysis was conducted using a 44-k whole human genome microarray. Labeling and hybridization were performed using a FairPlay microarray labeling kit, followed by the coupling of Cy3 (controls) or Cy5 (treated samples) dye. The hybridized slides were scanned using a GenePix 4000B microarray scanner, and the images were analyzed using GenePix 4.1 software to obtain gene expression ratios. The fluorescence intensity of each spot was calculated by local median background subtraction. We then used the robust scatter-plot smoother LOWESS function to perform intensity-dependent normalization of gene expression. Scatter-plot analysis was performed using Microsoft Excel 2000. A significance analysis of microarray (SAM) was performed for genes with significant changes in expression.

Project description:In the present study, an oligonucleotide microarray platform was used to compare expression profiles of heart and blood in rats treated with amiodarone against respective controls. Male Sprague-Dawley (CD) rats, which were 10 weeks old and weighed 290-320 grams at the beginning of the study, have been treated for ten days with amiodarone by oral route at a dose of 300mg/Kg/die. The study has been constituted by a control group, which received the vehicle (methylcellulose 1%, w/v), and by a treatment group (10 animals for both groups). For each tissue sample, total RNA has been individually extracted and evaluated. For each tissue, three pools/group (2 pools composed of 3 animals and the last one by 4) have been used for microarray analysis. A modulation of 600 genes in heart and 8300 genes in blood has been obtained.
