The effect of environmental salinity on the proteome of the sea bass (Dicentrarchus labrax L.)
Provedor de dados: 5
Autores: Ky, Chin Long; De Lorgeril, Julien; Hirtz, C; Sommerer, N; Rossignol, M; Bonhomme, F.
The European sea bass, Dicentrarchus labrax L., tolerates a range of salinities from freshwater to hyper-saline. To study differences in protein expression, fish were reared in both freshwater and seawater. After 3-month acclimation, gill and intestine epithelia were collected and the soluble protein extracted. In all, 362 spots were differentially expressed in the gills and intestines of fishes reared in seawater compared to those from freshwater. Fifty differential protein spots were excised from a colloidal Coomassie-stained gel. Nine separate protein spots were identified unambiguously by mass spectrometry and database searching. Among the six proteins over-expressed in gill cells in seawater, five were cytoskeleton proteins and one was the aromatase...

A transcriptomic approach of salinity response in the euryhaline teleost, Dicentrarchus labrax
Provedor de dados: 5
Autores: Boutet, Isabelle; Ky, Chin Long; Bonhomme, Francois.
Euryhaline teleosts possess the capacity to osmoregulate under various environmental conditions (freshwater to hypersaline water). This physiological capacity is generally monitored using enzyme activity assays (Na+/K+-ATPase...), hormones quantification (prolactine, growth hormone) or their mRNAs expression. To date, few studies addressed the genetic correlates of adaptation to varying salinity at a molecular level in such fish. In the sea bass Dicentrarchus labrax, genetic differentiation was observed at specific allozyme loci between lagoon- and open-sea populations. In the present study, we investigated transcriptomic response of D. labrax to salt- and freshwater acclimation in two organs involved in osmoregulation, gill and intestine. By using...
