(Submitter supplied) We investigated transcriptional and translational changes in rete mirabile tissue of European yellow and silver eels. We therefore analyzed the transcriptome as well as the proteome of rete capillaries of specimens of both developmental stages. The results clearly show the presence of a large number of membrane transport proteins in the transcriptome as well as in the proteome. ATP required to energize ion and metabolite transport can be generated in the aerobic metabolism. more...

(Submitter supplied) In spite of many decades of research, the spawning migration of the European eel Anguilla anguilla from the European coast to the Sargasso Sea remains a mystery. In particular, the role of the swimbladder as a buoyancy regulating structure is not yet understood. In this study, we exercised silver eels in a swim tunnel under elevated hydrostatic pressure. The transcriptome of gas gland tissue of these exercised eels was then compared to the known transcriptome of not exercised (control) silver eel gas gland cells. more...

(Submitter supplied) We investigated transcriptional changes caused by the nematode Anguillicola crassus within yellow and silver eels by comparing gas gland tissues of uninfected yellow with infected yellow eels, and uninfected silver with infected silver eels, respectively. In yellow eel gas gland, the infection caused a modification of steady state mRNA levels of 1675 genes, most of them being upregulated. Functional annotation analysis based on GO terms was used to categorize identified genes with regard to swimbladder metabolism or response to the infection. 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...
