Atlantic salmon liver transcriptome response to exposure to three human pharmaceuticals

ABSTRACT: The combination of increasing consumption rates and limited elimination under conventional waste water treatment practices of many pharmaceutical compounds has now led to their detection in aquatic environments. Three of the most frequently detected pharmaceuticals in the environment are Acetaminophen (APAP), Atenolol (AT) and Carbamazepine (CBZ). Atlantic salmon (parr) was exposed to environmentally relevant levels of Acetaminophen (APAP) (54.77 ± 34.67 µg·L-1), Atenolol (AT) (11.08 ± 7.98 µg·L-1) and Carbamzepine (CBZ) (7.85 ± 0.13 µg·L-1). Gene expression was analyzed in liver tissues using a 16K GRASP (University of Victoria, Canada) cDNA microarray. GRASP 16K v.2 cDNA microarrays were used for this study (Accession # A-GEOD-2716). A dual-labelled experimental design was employed for the microarray hybridisations. Each experimental cDNA sample (Cy3 labeled) was competitively hybridised against a common pooled-reference sample (Cy5 labeled). The entire experiment comprised 20 hybridisations - 4 states (APAP, AT, CBZ, control) × 1 time-point ( at 5 days) × 5 biological replicates (males only). Hybridisations were undertaken concurrently.

Transcription profiling by array of salmon parr brain after exposure to the carbamazepine

Project description:Concerns have arisen recently over the possible environmental effects of human pharmaceuticals. Although acute toxicities are low, the continuous discharge of pharmaceuticals into the aquatic environment, coupled with the fact that such compounds are selected for use on the basis of a strong pharmacological effect, means that sublethal effects on non-target organisms need to be seriously considered. The juvenile stages of Atlantic salmon are present in many northern European rivers which are also used for the discharge of domestic wastewaters likely to contain pharmaceuticals. One year old salmon parr were exposed to an environmentally relevant concentration (5µg·/ L) of the antidepressant drug carbamazepine for five days and changes of mRNA expression in brain tissues were investigated by means of a custom 17k Atlantic salmon cDNA microarray. The TRAITS 17K Atlantic salmon cDNA microarray was employed. A dual-labelled experimental design was employed for the microarray hybridisations. Each experimental cDNA sample (Cy3 labeled) was competitively hybridised against a common pooled-reference sample (Cy5 labeled). The entire experiment comprised 10 hybridisations - 2 states (CBZ exposed / unexposed) × 1 time-point ( at 5 days) × 5 biological replicates (males only). Hybridisations were undertaken concurrently.

Transcription profiling of Atlantic salmon following dietary substitution of fish oil with vegetable oils

Project description:There is an increasing drive to replace fish oil (FO) in finfish aquaculture diets with vegetable oils (VO), driven by the short supply of FO derived from wild fish stocks. Little is known of the consequences for fish health after such substitution. The effect of dietary VO on hepatic gene expression was determined in Atlantic salmon (Salmo salar) byg a cDNA microarray analysis. Post-smolt farmed salmon were reared for x weeks on diets where the FO component of the feed was replaced with one of three different VOs - rapeseed (RO), soybean (SO) or linseed (LO). RNA from five fish fed on each diet was extracted. A total of 20 cDNA microarray hybridisations - TRAITS / SGP Atlantic salmon 17k feature cDNA microarray - were performed - 4 diets (three VO + FO control) x 5 individuals - using a common pooled reference control design. Data were obtained from 19 of the 20 hybridisations.

Genotype-specific responses in hepatic lipid metabolism to complete dietary fish oil replacement by vegetable oil in Atlantic salmon

Project description:As part of a study investigating the effects of genotype on responses to sustainable feeds in Atlantic salmon, a microarray analysis of the liver transcriptome of two family groups, identified as 'Lean' or 'Fat' (based on flesh lipid content), which were fed a diet containing either 100% fish oil (FO) or 100% vegetable oil (VO) was undertaken. Cholesterol and lipoprotein metabolism pathways that were differentially affected by diet depending on the genetic background of the fish were identified.<br><br>The TRAITS/SGP (v.2.1) salmon 17k cDNA microarray was used in this experiment. A dual-labelled experimental design was employed for the microarray hybridisations. aRNA from each experimental sample (Cy3 labelled) was competitively hybridised against a common pooled-reference sample (Cy5 labelled), which comprised equal amounts of aRNA from each of the samples used in the study. This design permits valid statistical comparisons across all treatments to be made. The entire experiment comprised 24 hybridisations - 2 lipid phenotypes (Lean/Fat) × 2 diets (FO/VO) × 6 biological replicates.

Transcriptional response of Atlantic salmon (Salmo salar) to fish oil vs vegetable oil based diets

Project description:The effect of different diets (i.e. fish oil based vs vegetable oil based) on liver transcription profiles over the life history stages (freshwater and marine phases) of cultured Atlantic salmon (Salmo salar) were explored. Two groups of fish were raised from first feeding on different lipid containing diets; a) the standard 100% fish oil based diet, the other enriched with a blend of vegetable oils (75%) + fish oil (25%). Liver samples were taken from fish at four time points: two freshwater phase (as parr 36 weeks post hatch (wph); as pre-smolts, 52 wph) and two marine phase ( as post-smolts 55 wph; and as adult fish , 86 wph). A total of 96 cDNA microarray hybridisations - TRAITS / SGP Atlantic salmon 17k feature cDNA microarray - were performed ( 2 diets x 4 time points x 6 biological replicates x 2 -dye swap) using a comon pooled reference contol design.

gene expression profile of CBZ treated mice

Project description:Carbamazepine (CBZ) is widely used in the treatment of neuropsychiatric disorders as an anticonvulsant. A recent report revealed that CBZ has an anti-fibrotic effect on the livers of M-NM-11-antitrypsin-deficient mice, raising the possibility of a hepatology-related therapeutic use for the drug.Given the fact that CBZ has complicated pharmacokinetic properties, to comprehensively understand the its mechanism of action, we performed microarray analysis of the mouse liver tissues 2 hours after CBZ administration. The mice were orally administered 250 mg/kg of CBZ or DMSO and examined for the gene expression 2 hours later; 3 mice per group.

Hepatic proteome analysis of Atlantic salmon (Salmo salar) after exposure to environmental concentrations of human pharmaceuticals

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.
