Project description:This study aimed to investigate the transcriptional differences to metal exposure in two populations of Brown trout. These trout were taken from two separate locations, one population with historic exposure to metals and evidence of metal tolerance, and a second population from a clean environment. These fish were then exposed to metals within a laboratory environment and the transcriptional response before and after exposure was assessed in both liver and gill tissues. Six biological replicates were taken from each condition/population/tissue combination.

Project description:A total of 55 individuals were analysed: 15 migratory brown trout (Salmo trutta) individuals from the Redon river, 15 sedentary brown trout (S. trutta) individuals from the Redon river, 15 sedentary brown trout (S. trutta) individuals from the Chevenne river, and 10 Atlantic salmon (S. salar) individuals of a hatchery strain. For each individual, RNA was isolated twice from different parts of the same tissue, independently reverse transcribed into Cy3-labeled cDNA and then probed on two different slides, which leads to total of 110 single slide experiments.

Project description:These studies aimed to investigate the hepatic transcriptional response of brown trout to the natural estrogen, E2, and the herbicide linuron. We exposed mature male brown trout to three concentrations of each chemical for 4 days and sequenced the hepatic transcriptome of 3 individuals per treatment group in order to determine the global mechanisms of toxicity of these environmental contaminants. We assembled the brown trout transcriptome using a de novo approach. Subsequent differential expression analysis identified a total of 2113 differentially-regulated transcripts in the group exposed to the highest E2 treatment concentration, and 822 differentially-regulated transcripts across all linuron treatments. For E2, differentially-expressed transcripts included those encoding known oestrogen-responsive genes, while regulated processes included those associated with vitellogenesis including lipid metabolism, cellular proliferation and ribosome biogenesis. For linuron, there was a striking down-regulation of transcripts encoding the majority of the enzymes involved in the cholesterol biosynthesis pathway, and also a considerable induction of transcripts involved in cellular stress response including Cyp1a.

Project description:This study aimed to investigate the hepatic transcriptional response of brown trout to glyphosate, and its formulated product, Roundup. We exposed juvenile female brown trout to three concentrations of glyphosate (0.01, 0.5 and 10 mg/L) and Roundup (0.01, 0.5 and 10 mg/L glyphosate acid equivalent) for 14 days and sequenced the hepatic transcriptome of 6 individual females per treatment group in order to determine the global mechanisms of toxicity of this widely used herbicide. We assembled the brown trout transcriptome using an optimised de novo approach, and subsequent differential expression analysis identified a total of 1020 differentially-regulated transcripts across all treatments. Differentially-expressed transcripts included those encoding components of the antioxidant system, a number of stress-response proteins and pro-apoptotic signalling molecules. Functional analysis also revealed over-representation of pathways involved in regulation of cell-proliferation and turnover, and up-regulation of energy metabolism and other metabolic processes. Together, these transcriptional changes are consistent with generation of oxidative stress and the widespread induction of compensatory cellular stress response pathways. The mechanisms of toxicity identified were similar across both glyphosate and Roundup treatments, including for environmentally relevant concentrations. The significant alterations in transcript expression observed at the lowest concentrations tested raises concerns for the toxicity of this herbicide to fish populations inhabiting contaminated rivers.
