(Submitter supplied) An European eel-specific microarray platform was developed to identify genes involved in response to pollutants. A comparative analysis of gene expression was conducted between European eel Anguilla anguilla individuals from lowly-polluted Wijmeers pond at Uitbergen (Belgium), highly-polluted Hazewinkel pond at Willebroek (Belgium), extremely-polluted Dessel-Schotel canal at the locations of Schotel (Belgium) and low polluted Bolsena lake (Italy) environments.

(Submitter supplied) Toxic compounds such as organochlorine pesticides (OCs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ether flame retardants (PBDEs) have been detected in fish, birds, and aquatic mammals that live in the Columbia River or use the river as a food source. We developed a custom microarray for largescale suckers (Catostomus macrocheilus) and used it to investigate the molecular effects of contaminant exposure on wild fish in the Columbia River. more...

(Submitter supplied) This project aims to study the role played by small non-coding RNAs in the response of aquatic organisms to the presence of micropollutants in the environment. MiRNA were purified from Eels (Anguilla anguilla) sampled from two sites along the Gironde aquatic system with contrasted pollution profiles.

(Submitter supplied) Nanometric revolution is underway, promising technical innovations in a wide range of applications, leading to a potential boost in environmental discharges. Nanoparticle propensity to be transferred throughout trophic chains and to generate toxicity was mainly assessed in primary consumers while a lack of knowledge for higher trophic levels persists. This study focused on a predatory fish, the European eel Anguilla anguilla exposed to gold nanoparticles (AuNP, 10 nm, PEG-coated) for 21 days at three concentration levels in food: 0 (NP0), 1 (NP1) and 10 (NP10) mg Au.kg-1 . more...

(Submitter supplied) The goal of this study was to gain a better understanding of the genetic background of gonadal maturation of the European eel and to use gene expression profiles to identify predictive markers for broodstock selection that can be measured in blood samples. Three-year-old farmed silver female European eels were injected with 20 mg salmon pituitary extract (SPE) once per week and sampled after 4 weekly hormone injections. more...

(Submitter supplied) The goal of this study was to gain a better understanding of the genetic background of gonadal maturation of the European eel and to use gene expression profiles to identify predictive markers for broodstock selection that can be measured in blood samples. To find leads for maturation markers we performed a pilot deep-sequencing transcriptome analysis of ovarian tissue derived from a yellow eel, a prepubertal silver eel and a post-spawning matured eel. more...

(Submitter supplied) Methylmercury (MeHg) is a highly toxic environmental pollutant. To understand the mechanisms of toxicity of the compound and possibly to discover new biomarkers for environmental monitoring, we have conducted toxicogenomics studies. We designed 126k-cod-oligonucleotide arrays and performed genome-wide gene expression assays in liver samples from juvenile cod treated with MeHg (0.5 and 2 mg/kg body weight). more...

(Submitter supplied) Gene expression analyses have been performed on liver tissue of sexually mature and immature males using microarrays. 60 eels were transferred to two independent temperature controlled recirculation water units connected to two 500 L cylindro-conical tanks (30 fish per tank) where the fish were acclimated to seawater (35 PSU salinity) over a 2 week period.Eel males in one of the seawater units were injected intramuscularly every week over a 140 day period with 2000 IU hCG/kg (human chorionic gonadotropin, Sigma–Aldrich Chemical) dissolved in 0.9% saline to induce sexual maturation. more...

(Submitter supplied) Changes in hepatic gene expression profiles upon exposures to cadmium applied by feeding or intra-peritoneal injections were identified in the striped sea bream (Lithognathus mormyrus) using cDNA microarray platform. Two groups of four fish were exposed to fed and injected CdCl2, respectively. Additional eight untreated fish were used as a reference group, pooled into 4 hepatic RNA preparations. The isolated hepatic mRNAs were hybridized, after conversion to labeled cDNAs, onto the microarray followed by slide scanning, imaging and analysis. more...
