(Submitter supplied) To characterise the transcriptional response in brain of Sockeye Salmon (Oncorhynchus nerka) that were persistently infected with infectious hematopoietic necrosis virus (IHNV) and to determine whether carrying the IHNV affects the ability to respond to other immunological challenges we compared the brain transcriptome of IHNV carriers, IHNV-negative survivors, and naïve Sockeye Salmon that were never exposed to IHNV. more...

(Submitter supplied) Following an infection with a specific pathogen, the acquired immune system of many teleostean fish, including salmonids, is known to retain a specific memory of the infectious agent, which protects the host against subsequent infections. For example Atlantic salmon (Salmo salar), which have survived an infection with a low-virulence infectious salmon anemia virus (ISAV) isolate are less susceptible against subsequent infections with high-virulence ISAV isolates. more...

(Submitter supplied) The Infectious Hematopoietic Necrosic Virus (IHNV) DNA vaccine is based on the viral glycoprotein gene (G gene) and induces a non-specific anti-viral immune response and long-term specific immunity against IHNV in salmonid fishes. This study characterized gene expression responses associated with the early anti-viral response. Homozygous rainbow trout were injected intra-muscularly (I.M.) with vector DNA or the IHNV DNA vaccine. more...

(Submitter supplied) The response of the trout, O.mykiss, head kidney to bacterial lipopolysaccharide (LPS) or active and attenuated infectious hematopoietic necrosis virus (IHNV and attINHV respectively) intraperoniteal challenge, 24 and 72 hours post-injection, was investigated using a salmonid-specific cDNA microarray. The head kidney response to i.p. LPS-induced inflammation in the first instance displays an initial stress reaction involving suppression of major cellular processes, including immune function, followed by a proliferative hematopoietic-type/biogenesis response 3 days after administration. more...

(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...

(Submitter supplied) This dataset was gene expression from natural sockeye salmon populations used to test the preservation of coexpression networks that were found in lake whitefish. Here is the abstract of the manuscript:Background : A functional understanding of processes involved in adaptive divergence is one of the awaiting opportunities afforded by high throughput transcriptomic technologies. Functional analysis of co-expressed genes has succeeded in the biomedical field in identifying key drivers of disease pathways. more...
