Diploid and triploid Chinook salmon (Oncorhynchus tshawytscha) have altered microRNA responses in immune tissues after infection with Vibrio anguillarum

(Submitter supplied) Production of sterile fishes through artificial retention of a third set of chromosomes (triploidy) is a sustainable alternative for aquaculture since it reduces pressure on wild populations. However, these fishes have reduced survival in stressful conditions and in response to pathogens. In this study, the impact of Vibrio anguillarum infection on diploid and triploid Chinook salmon (Oncorhynchus tshawytscha) was investigated to identify if there was any significant regulation by microRNAs (miRNA) in immune responsive tissues. more...

Regulation of Host Gene Expression by Gastrointestinal Tract Microbiota

(Submitter supplied) Difference in gut microbiome is linked with health, disease and eventually host fitness, however, the molecular mechanisms by which this variation affects the host fitness are not well characterized. Here, we modified the fish gut microbiota by using antibiotic and probiotic to address the effect of host microbiome on gene expression pattern by using transcriptome.

Transciptional response to acute thermal stress in Chinook salmon

(Submitter supplied) Thermal stress is a serious and growing challenge facing Chinook salmon (Oncorhynchus tshawytscha) living in the southern portion of their native range. River alterations have increased the likelihood that juveniles will be exposed to warm water temperatures during their freshwater life stage, which can negatively impact survival, growth, and development and poses a threat to dwindling salmon populations. more...

Gene expression in natural subyearling fall Chinook salmon in the Snake and Clearwater Rivers

(Submitter supplied) We used gene expression accompanied by physical characteristics and gill Na+/K+-ATPase activity to analyze physiological differences associated with two life history variations of juvenile fall Chinook Salmon in the Snake River basin. Subyearlings originating in the Snake River typically migrate seaward as subyearlings, whereas many subyearlings from the Clearwater River delay seaward migration during summer and complete seaward migration the following spring as yearlings. more...

Effects of domestication and GH transgenesis on mRNA profiles in rainbow trout

(Submitter supplied) Growth rate can be genetically modified in many vertebrates by domestication and selection, and more recently by transgenesis overexpressing growth factor genes (e.g. growth hormone, GH). While the phenotypic end consequence is similar, it is currently not clear whether the same modifications to physiological pathways are occurring in both genetic processes, nor to what extent they may interact when combined. more...

Toxic effects of dietary methylmercury (MeHg) on juvenile rainbow trout

(Submitter supplied) Juvenile rainbow trout were fed Biodiet starter (4% body weight per day) with MeHg added at 0, 0.5, 5 and 50 ppm for six weeks. Atomic absorption spectrometry was applied to measure the level of MeHg in the whole fish body. Trout at six weeks were sampled from each group for gene expression analysis by cGRASP 16K cDNA microarrays. MeHg-exposed rainbow trout did not show overt signs of toxicity, nor were significant differences seen in mortality, length, mass, or condition factor. more...

Salvelinus Microarray experiment: The influence of parental effects on transcriptomic landscape during early development in brook charr (Salvelinus fontinalis, Mitchill)

(Submitter supplied) Parental effects represent an important source of variation in offspring phenotypes. Depending on the specific mechanisms involved, parental effects may be caused to different degrees by either the maternal or paternal parent, and these effects may in turn act at different stages of development. In order to detect parental effects acting on gene transcription regulation and length phenotype during ontogeny, the transcriptomic profiles of two reciprocal hybrids from Laval × Rupert and Laval × domestic populations of brook charr were compared at hatching, yolk sac resorption, and 15 weeks after exogenous feeding. more...

Gene expression in liver, gill, hypothalamus, pituitary, and olfactory rosettes from Atlantic salmon parr and smolt

(Submitter supplied) To identify genes involved in the developmental process of Atlantic salmon smoltification, gene expression was compared between smolt and parr in tissues involved in osmoregulation (gill), metabolism (liver), imprinting (olfactory rosettes) and neuroendocrine control (hypothalamus and pituitary). Tissue samples were harvested from laboratory-reared parr and smolts on the same date. Smolts were distinguished from parr by size and appearance; developmental status was confirmed by physiological assays.

Effect of nonylphenol on gene expression in Atlantic salmon liver, gill, hypothalamus, pituitary, and olfactory rosettes

(Submitter supplied) Exposure to environmental contaminants like nonylphenol can disrupt smolt development and may be a contributing factor in salmon population declines. We used GRASP 16K cDNA microarrays to identify genes that are differentially expressed in the liver, gill, hypothalamus, pituitary, and olfactory rosettes of Atlantic salmon smolts treated with nonylphenol compared to control smolts. Nonylphenol treatment was confirmed using physiological assays: nonylphenol-treatment significantly decreased gill Na+,K+-ATPase activity and plasma cortisol and T3 levels.

Consequences of high temperatures and premature mortality on the transcriptome and blood physiology of wild adult sockeye salmon (Oncorhynchus nerka)

(Submitter supplied) We collected sockeye salmon from the Fraser River, British Columbia, and held them at ecologically relevant temperatures (14C and 19C) determine the effect of elevated water temperature on cellular processes in non-lethally sampled gill tissue and blood plasma over a period of seven days that represents a significant portion of their upstream migration. Time-matched fish that died prematurely over the course of the holding study were also sampled for gill tissue and the transcriptomic responses in moribund fish were compared with surviving fish. more...

Identification of a responsive gene set to evaluate the potential impact of seismic exposure on Atlantic salmon (Salmo salar) inner ear

(Submitter supplied) Considerable interest and controversy has arisen over the potential effects of seismic surveys carried out during exploration for oil and gas deposits. Regarding fish, there is a concern that intense sound sources, such as seismic airguns, may injure their auditory system. In this study, salmonid cDNA microarrays and quantitative reverse transcription – polymerase chain reaction (QPCR) were used to identify and study a responsive gene set in the inner ear of Atlantic salmon (Salmo salar) following seismic airgun exposure. more...

Pacific salmon gill samples: fate tracking in river

(Submitter supplied) The long-term viability of Pacific salmon stocks and the fisheries they support are threatened if large numbers die prematurely en-route to spawning grounds. Physiological profiles that were correlated with the fate of wild sockeye salmon during river migration were discovered using functional genomics studies on biopsied tissues. Three independent biotelemetry studies tracked the biopsied fish after tagging in the marine environment over 200 km from the Fraser River, in the lower river 69 km from the river mouth and at the spawning grounds. more...

Rainbow trout red blood cells (RBCs): Control vs Heat shock, repeated samples from individuals

(Submitter supplied) The retention of a nucleus in the mature state of fish red blood cells (RBCs), and the ability to easily collect and manipulate blood in non-terminal experiments, makes it an ideal tissue on which to study the cellular stress response in fish. Through the use of the cGRASP 16K salmonid microarray, we are currently investigating differences in RBC global gene transcription in fish held under control conditions (12C) and exposed to heat stress (one hour at 25C followed by recovery at 12C). more...
