Project description:The aim of this sequencing experiment was to make available tissue expression panels for selected fish species for comparative expression studies between the species. Tissue samples were collected for zebrafish (Danio rerio), medaka (Oryzias latipes), and rainbow trout (Oncorhynchus mykiss). Tissue types included liver, skin, muscle, heart, gut, gill, eye, brain for all three species, with additionally pyloric caeca, kidney, head kidney, and spleen for rainbow trout. Only liver samples were taken in replicate of four or three for rainbow trout. All fish were raised under standard rearing conditions for the species. Total RNA was extracted from the tissue samples and paired‐end sequencing of sample libraries was completed on an Illumina HiSeq 2500 with 125‐bp reads. Processed count tables per species as raw counts, FPKM, or TPM, were generated from read alignment to the Ensembl genomes of the respective species using STAR and gene level counting using RSEM and Ensembl gene annotation.

We report here an study of the transcripts in head kidney and pyloric ceca 7 days after oral vaccination of rainbow trout by using a newly designed rainbow trout 60-mer oligo microarray focused in their immune-related genes. Trout were obtained from 4 different farms, one group of trout was defined as belonging to one of the farms. Each of the trout 4 groups were divided into two subgroups of 6 trout for each subgroup. Subgroup I was orally vaccinated with 10 M-BM-5l of suspension of the vaccine microspheres each containing 10 M-BM-5g of pcDNA-VP2 diluted in 10M-BM-5l of PBS, while subgroup II received similar microspheres suspension but pcDNA. Head kidney and pyloric ceca were collected from each subgroup and RNA was extracted.

Project description:The objective of this study was to identify and quantify proteomic profiles of head kidney of rainbow trout Oncorhynchus mykiss. Specific pathogen free rainbow trout (mean length 15 ± 1 cm) were maintained in recirculating de-chlorinated water at 19±1 °C. Prior to the experiment, fish were distributed between 9 aquaria, 18 fish per aquarium. The test groups were infected by immersion of Yersinia ruckeri strains: CSF007-82 (biotype 1) and 7959-11 (biotype 2). The control group was immersed similar with sterile broth medium. There were 3 aquaria per each group (CSF007-82-infected, 7959-11-infected and control). Nine fish from infected and control fish groups were anaesthetized with MS-222 at 3, 9 and 28 days post exposure and sampled aseptically. Each head kidney was washed three times with sterile phosphate-buffered saline containing a cocktail of mammalian protease inhibitors. Head kidney samples were snap-frozen in liquid nitrogen and stored at –80 °C.

Project description:The effect of dietary immunostimulation in the immune organs, head kidney and spleen, of rainbow trout (Oncorhynchus mykiss), was investigated using a salmonid-specific microarray platform enriched with immune-related genes. Immunostimulant-diet feeding significantly changed transcriptomic expression profiles: larger reduction rather than induction was observed, with significant regulation in genes and functional GO categories related to remodeling processes and immune and hematopoietic activities. The results revealed that Immunostimulant-diets hava effect in the transcriptome of cultured fish. Keywords: spleen, head kidney, immunostimulats, transcriptomic response, trout

Project description:In mammals, increasing data suggests that there exists a complex and bi-directional relationship between thyroid and immune systems. However the existence of such interactions in fish is unknown. Here, we administered the biologically active hormone 3.3�.5-triiodo-L-thyronine (T3) and the anti-thyroid drug, propilthiouracil (PTU) to juvenile rainbow trout and examined the head kidney expression profile with a custom-made microarray enriched in immune-related genes. A seven day-experiment was performed. Fish were divided in 3 groups. First group received 20 µg/g fish feed of T3; second group received 5000 µg/g fish feed of PTU; third group served as control. After 7 days orally administering T3 or PTU, differentially expressed transcript levels from selected immune-related rainbow trout genes were studied in head kidney. Three groups were studied (T3-treated, PTU treated and control), each group having 4 biological replicates (each replicate consisting of 2 pooled fish).

Project description:Rainbow trout (Oncorhynchus mykiss) is an important cold-water fish widely cultivated in China. The frequent occurrence of viral diseases caused by infectious hematopoietic necrosis virus (IHNV) seriously restricted the healthy development of the rainbow trout farming industry. However, the immune defense mechanism induced by IHNV in rainbow trout has not been fully elucidated. In the present study, we detected mRNA and miRNA expression profiles in rainbow trout head kidney after IHNV infection and the expression patterns of key immune-related genes at different post-infection periods (0-, 6-, 12-, 24-, 48-, 72-, 96-, 120- and 144 hours post-infection (hpi)) using RNA-seq and qRT-PCR. The results showed that a total of 7486 genes and 277 miRNAs were differentially expressed, and numerous differentially expressed genes (DEGs) enriched in the immune-related pathways such as Toll-like receptor signaling pathway, RIG-I-like receptor signaling pathway, NOD-like receptor signaling pathway, cytokine-cytokine receptor interaction and JAK-STAT signaling pathway were significantly up-regulated, including LGP2, MDA5, TRIM25, IRF3, IRF7, TLR3, TLR7, TLR8, MYD88, IFN1, MX1 and VIG-1. Integration analysis identified six miRNAs (miR-141-y, miR-200-y, miR-144-y, miR-2188-y, miR-725-y and miR-203-y) that target at least four key immune-related genes (TRIM25, LGP2, TLR3, TLR7, IRF3 and IRF7). Expression analysis showed that TRIM25, MDA5, LGP2, TLR3, TLR7, IRF3, IRF7, IFN1, MX1 and VIG-1 genes increased firstly and then decreased, and reached peak expression at 48 hpi. These findings improve our understanding of the immune mechanism of rainbow trout infected with IHNV, and provide a basic data for future breeding for disease resistance in rainbow trout.

Project description:We describe here transcripts induced after intraperitoneal injection of rainbow trout with 2 different viruses, both belonging to strain 23.75 of viral hemorrhagic septicemia virus (VHSV): a deleted Nv gene (dNV) virus and a wild type (wt) virus. Two days after infection, differentially expressed transcript levels from selected immune-related trout genes were studied in internal organs (spleen and head kidney). Fishes were divided in two groups (3 fishes per group). The first group was intraperitoneally injected with 100000 pfu per trout of dNV VHSV, while the second group was injected with 100000 pfu/trout of wt VHSV. All fishes were sacrificed two days post infection.
