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: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 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.

Project description:Purpose:Our data significantly advance understanding of heat stress regulatory mechanism of miRNA in the head kidney of rainbow trout Methods:miRNAs of rainbow trout were involved in heat stress were identified by high-throughput sequencing of six small RNA libraries of the kidney tissues under control (18℃) and heat-treated (24℃) conditions Results:high-throughput sequencing was performed to identify miRNAs responsive to heat stress. We obtained 41,991,119 and 43,882,123 raw reads and 39,756,736 and 42,538,331 clean reads from under control (18℃) and heat-treated (24℃) .A total of 392 conserved miRNAs and 989 novel miRNAs were identified, of which 78 miRNAs were expressed in different response to heat stress. In addition to, including 393 negative correlation miRNA-target gene pairs Conclusions:through high-throughput sequencing of the six libraries from head kidney tissue of rainbow trout, the expression level of miRNA has significant changes after heat stress.

Project description:Stocking density is considered as a key factor determining the productivity of fish aquaculture systems. The transcriptomic response to crowding stress is, however, still poorly investigated. We aimed at the identification of potential biomarker genes via microarray analyses to get insight into molecular pathways modulated through density-induced stress in farmed rainbow trout Oncorhynchus mykiss. Transcriptome profiling in liver, kidney, and gills was complemented with behaviarol observation and analysis of classical plasma parameters. Individuals of two trout strains were exposed for eight days to definite stocking densities, 1 kg/m³ (low density); 10 kg/m³ (moderate); 18 kg/m³ (elevated); and 35 kg/m³ (high). Whereas stocking density had no significant effect on cortisol levels, plasma glucose levels were elevated in trout kept at high density. Pathway enrichment analyses confirmed the upregulation of HIF1a signaling in liver contributing to glucose homeostasis during stress conditions, while mTOR and PI3K/AKT signaling pathways were downregulated. Further perturbed hepatic pathways were involved in protein ubiquitination and the biosynthesis of cholesterol, retinol and glutathione. Three stocking density conditions were investigated: an uncrowded âmoderateâ density (MD: 10 kg trout/m³) , an elevated density (ED: 18 kg/m³ ), and high density (HD: 35 kg/m³). The experiment was performed twice with two strains of Steelhead rainbow trout (Troutlodge and Born trout), randomly assigned to identical glass tanks with MD (30 and 34 individuals), ED (60 and 64 individuals), and HD (120 and 140 individuals). Trout were sampled 8 d after experimental onset.
