Project description:Using an ex-vivo testicular culture from rats, we carried out transcriptomic experiments to identify the pathway of toxicity ellicited by the fungicides carbendazim, iprodione alone or in combination. we used commercial Agilent Microarray GE 4x44K Rat (V3) Gene Expression Microarray (G2514F) AMADID : 028282

Project description:Carbendazim (Methyl benzimidazol-2-ylcarbamate; MBC) is an antimitotic drug used for broad-spectrum fungicide, antineoplastic and mutagen in microbial breeding. Using a customized SNP microarray technology, this work revealed the effect of MBC on genomic instability (loss of heterozygosity, chromosomal rearrangements and aneuploidy) in the diploid yeast Saccharomyces cerevisiae JSC25.

Project description:Pesticides are continuously released into the environment, with possible long-term consequences on aquatic organisms. One of the pesticides still applied in several crops in some countries is the fungicide carbendazim, ending up in surface waters with concentrations reaching 5 µg/L. Daphnia magna (clone k6) was used in this study as a model organism and it was exposed to a sub-lethal concentration of carbendazim (5 µg/L) for twelve generations. Gene expression alterations induced by this compound were assessed in the F0 and F12 generations using D. magna custom microarrays. Results revealed that carbendazim caused changes at the gene expression level in both generations. Genes involved in response to stress, DNA replication/repair, neurotransmission, protein biosynthesis, ATP production, lipids and carbohydrates metabolism were the most affected in both F0 and F12, although a lower number of differentially expressed genes were observed in the F12 generation exposed to carbendazim. The exposure of daphnids to carbendazim did not cause a stable change in gene expression from F0 to F12 generations. Effects at the gene expression level were early detected at the F0 generation after a short-time exposure (10 days), highlighting the advantages of using high throughput tools as early warning analysis but also providing information on chemical mode of action, which can add value in risk assessment procedures.

Project description:Background: Molecular mechanisms of response to pesticides are scarce and information on such responses from soil invertebrates is almost inexistent. Enchytraeus albidus (Oligochaeta) is a standard soil ecotoxicology model species for which effects of many pesticides are known on survival, reproduction and avoidance behaviour. With the recent microarray development additional information can be retrieved on the molecular effects. Methodology/Principal Findings: Experiments were performed to investigate the transcription responses of E. albidus when exposed to three pesticides M-bM-^@M-^S dimethoate (insecticide), atrazine (herbicide) and carbendazim (fungicide) M-bM-^@M-^S in a range of concentrations that inhibited reproduction by 10%, 20%, 50% and 90% (EC10, EC20, EC50 and EC90, respectively). The goal of this study was to further identify key biological processes affected by each compound and if dose-related. All three pesticides significantly affected biological processes like translation, regulation of the cell cycle or general response to stress. Intracellular signalling and microtubule-based movement were affected by dimethoate and carbendazim whereas atrazine affected lipid and steroid metabolism (also by dimethoate) or carbohydrate metabolism (also by carbendazim). Response to DNA damage/DNA repair was exclusively affected by carbendazim. Conclusions: Changes in gene expression were significantly altered after 2 days of exposure in a dose-related manner. The mechanisms of response were comparable with the ones for mammals, suggesting across species conserved modes of action. The present results indicate the potential of using gene expression in risk assessment and the advantage as early markers. Gene expression in E.albidus was measured at 2 days after exposure to dimethoate, atrazine and carbendazim at 4 concentrations of effect on reprocduction (EC10, EC20, EC50 and EC90). Three biological replicates per treatment were used.

For the microarray experiment, neonates with less than 24h were picked from the F0 and F12 generations from both clean medium and carbendazim. Three replicates per each treatment were used and consisted of 5 daphnids aging 10 days old. A total of three replicates per treatment were used and each biological replicate was individually hybridized on the array. A single-color design was used, using the Agilent one-color RNA Spike-In Kit (AgilentTechnologies, Santa Clara, CA, USA), following the manufacturers protocol.

Project description:In the present study OMICs analysis was employed to investigate the early molecular responses of zebrafish embryos to exposure to the fungicide metalaxyl. Metalaxyl, a nucleic acid metabolism inhibitor according to Fungicide Resistance Action Committee (FRAC) classification, may also induce adverse effects on non-target organisms inhabiting the environment. Early molecular responses in terms of transcriptome and proteome analysis were investigated and refined to select potentially substance specific biomarker candidates for early prediction of metalaxyl toxicity in zebrafish embryos.
