Project description:One of the most widely used drugs in municipal wastewater treatment effluents and soil is carbamazepine, a commonly prescribed antidepressants and antiepileptic drug. Carbamazepine exerts an intrinsic biological activity on the nervous system, thus may induce ecotoxicological effects on non-target organisms. Earthworms, one of the essential indicator species of soil health, accumulate biosolid fertilisers and wastewater contaminants. In this project, earthworms (Dendrobaena veneta) were treated with carbamazepine to explore their uptake dynamics, molecular and life cycle endpoints. By conducting transcriptomic profiling of different tissues in an organism exposed to carbamazepine assists in defining detoxification and neural system responses in the terrestrial invertebrate.

Project description:The goals of this study are to use SWATH-MS to detect bacterial proteomic profiles of wild-type E. coli K-12 LE392, P. putida KT2440, and their quantitative protein response under the exposure of antiepileptic drug carbamazepine. Three concentrations of carbamazepine were applied, which were 0.05 mg/L, 10.0 mg/L and 50.0 mg/L. The group without dosing carbamazepine was the control group. Each concentration was conducted in triplicate. By comparing the proteomic profiles of experimental groups and control group, the effects of carbamazepine on bacterial translational levels can be revealed.

Project description:Transcriptomic profiling of Daphnia magna samples exposed to carbamazepine (CBZ), diazepan (DZP), propranolol (PR) and to an equitoxic mixture of them (M). Assessing the risks of emerging contaminants such as neuro-active pharmaceuticals in the environment requires an understanding of their joint effects at low concentrations across species. Here, we assessed reproductive and transcriptional effect of propranolol, diazepam and carbamazepine on the crustacean Daphnia magna at environmentally relevant concentrations. The three compounds enhanced reproductive parameters in adults, and induced specific transcriptome changes in pre-adolescent individuals. Comparing results from single exposures and of ternary equi-effective mixtures showed additive action for both effects. Transcriptomic analyses identified 3248 genes affected by at least one of the treatment, which were grouped into four clusters. Two clusters included 1897 gene transcripts in total, that behaved similarly (appearing either over- or underrepresented relative to control) in single and mixture treatments. The third and fourth clusters grouped genes differently transcribed upon exposure to diazepam and propranolol, respectively. Functional transcriptomics indicated that the four clusters shared major de-regulated signalling pathways implicated on energy, growth, reproduction, and neurologically- related processes, which may be responsible for the observed reproductive effects. Our study, thus, showed additive effects at the transcriptional and physiological level and is providing a novel approach to the analysis of environmental relevant mixtures of neuro-active compounds

Project description:Horizontal transfer of plasmids is one of the main drivers of bacterial adaptation, resulting e.g. in the spread of antibiotic resistance. We investigated the marine Roseobacter group and studied how conjugation affects the gene expression and biology of the new host. We showed that the two syntenic 126 kb and 191 kb plasmids of Dinoroseobacter shibae can be conjugated into representatives of all major lineages of Rhodobacteraceae. In the model organism Phaeobacter inhibens their acquisition resulted in differential expression of genes related to motility, transport and the synthesis of vitamins. Moreover, the decrease of the potent antibiotic tropodithietic acid reduced the energetic burden of Phaeobacter and resulted in an enhanced growth. While the T4SS systems of both plasmids were silenced in the new host, the ability to kill the dinoflagellate was exclusively transferred via the 191 kb plasmid from D. shibae to P. inhibens. Our findings showed drastic consequences of plasmid conjugation; genetic reprogramming of the novel host resulted in considerable fitness changes leading to the prediction that horizontal gene transfer triggers bacterial speciation.

Project description:Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a severe, drug-induced reaction that involves both the skin and viscera. To understand the immunological components of DRESS, we prospectively assessed 40 DRESS patients. The patients were evaluated for phenotype, cytokine secretion, repertoire of CD4+ and CD8+ peripheral blood T lymphocytes and viral reactivation. A subgroup of patients was analyzed using microarrays. Patients with carbamazepine- or minocycline- induced DRESS were pooled separately for analysis. RNA from total PBMCs and CD4+ and CD8+-sorted blood T cells was amplified. Expression of 894 genes of immunological interest was analyzed with a PIQOR TM arrays (Miltenyi). Gene expression was individually compared between day 0 and 90 in the minocycline-induced DRESS patients. Control groups included patients taking minocycline carbamazepine, and healthy patients without medication.

Project description:Pharmaceuticals are pseudo persistent aquatic pollutants with unknown effects at environmentally relevant concentrations. Atlantic salmon (Salmo salar) were exposed to Acetaminophen: 54.77 ± 34.67; Atenolol: 11.08 ± 7.98 and Carbamazepine: 7.85 ± 0.13 µg•L-1 for 5 days. After Acetaminophen treatment, 19 proteins were differently expressed, of which 11 were significant with respect to the control group (eight up-regulated and three down-regulated). After Atenolol treatment, 7 differently expressed proteins were obtained in comparison with the control, of which 6 could be identified (four up-regulated and 2 down-regulated). Carbamazepine exposure resulted in 15 differently expressed proteins compared with the control, with 10 of them identified (seven up-regulated and three down-regulated). Out of these, 3 features were common between Acetaminophen and Carbamazepine and one between Carbamazepine and Atenolol. One feature was common across all treatments. Principal component analysis and heat map clustering showed a clear grouping of the variability due to the applied treatments. The obtained data suggest (1) that exposure to environmentally relevant concentrations of the pharmaceuticals alters the hepatic protein expression profile of the Atlantic salmon; and (2) the existence of treatment specific processes that may be useful for biomarker development.
