Project description:In the present work, we evaluated the effects of membrane-initiated cortisol actions in vivo in the proteome of rainbow trout (Oncorhynchus mykiss) skeletal muscle. Quantitative iTRAQ analyses were performed to examine proteomic changes in rainbow trout stimulated with physiological concentrations of cortisol and cortisol-BSA. A total of 873 proteins were identified, among which 38 proteins were commonly and differentially expressed under both conditions. Functional clustering analysis revealed an upregulation of proteins associated with mitochondria, metal-binding and secreted proteins.

Project description:Rainbow trout (Oncorhynchus mykiss) and other salmonids are piscivorous fish. In aquaculture, fish-based feed ingredients are rapidly becoming unsustainable due to increased demand and diminishing supply. Total replacement of fishmeal with plant proteins causes severe intestinal enteritis, leading to reduced growth and lower feed efficiency. Through selective breeding, we have developed a strain of rainbow trout that does not develop distal intestine enteritis when reared on a high soy plant protein-based feed and also shows increased growth compared to other strains. Since central metabolism plays a major role in dietary alterations, and as growth was a major factor in the selection program, both muscle and liver gene expression were examined for differential regulation between commercial and selected trout strains when fed alternative diets. After three months of rearing on either a fishmeal (FM) or plant protein-based (PM) diet, muscle and liver tissues from a domestic non-selected strain (House Creek; develops enteritis) and the selected strain (ARS-KO; no enteritis) were extracted and prepped for Illumina RNA-seq. Raw reads were screened for quality then aligned to the rainbow trout transcriptome. Read-counts were used to assess differential expression between strains and treatments. Significant differentially expressed genes between comparisons were assessed.

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:We have constructed a rainbow trout high-density oligonucleotide microarray by using all the available tentative consensus (TC) sequences from the Rainbow Trout Gene Index database (The Computational Biology and Functional Genomics Lab., Dana Farber Cancer Institute and Harvard School of Public Health). The Rainbow Trout Gene Index integrates research data from all available international rainbow trout genomic research projects. The newly designed microarray incorporates 37,394 unique transcript-specific oligonucleotide probes, 60-mer long each. The microarray was printed according to our design by Agilent Technologies using the 4 X 44-design format and contains 1417 Agilent control spots. The performance of the new microarray platform was evaluated by analyzing gene expression associated with the rainbow trout vitellogenesis-induced muscle atrophy. These chips can be ordered from Agilent using design number 016320. This microarray is anticipated to open new avenues of research that will aid in the development of novel strategies to enhance growth efficiency and quality in salmonid species. Keywords: Development of an oligo-array for rainbow trout The performance of the new microarray platform was evaluated by analyzing transcriptome response associated with the rainbow trout vitellogenesis-induced muscle atrophy. Severe muscle deterioration accompanies the physiological responses of the energetic demands of the rainbow trout spawning/vitellogenesis. Atrophying muscle of fertile fish had 11% less extractable muscle (g/bw) and 11% less protein content compared to non-atrophying muscle of sterile fish (p<0.01). The rainbow trout was used to profile changes in gene expression of atrophying muscles. Gene expression levels were determined by comparing the amount of mRNA transcript present in the experimental sample (fertile fish) to the control (sterile fish). RNAs isolated from each experimental fish were run on separate microarrays in independent experiments, with no pooling. A total of 8 fish were used in the microarray experiments (4 replicates x 2 groups). Fluorophors (Cy3 and Cy5) were randomly assigned to RNA from each of the atrophying and nonatrophying muscles to limit the dye effect.

Project description:Proteomics represents a powerful tool for the analysis of fish spermatozoa, since these cells are transcriptionally inactive. The aim of the present study was to generate an inventory of the most prominent rainbow trout sperm proteins with the use of one-dimensional electrophoresis prefractionation combined with performance liquid chromatography electrospray ionization tandem mass spectrometry. This study provides the first in-depth analysis of the rainbow trout sperm proteome, with a total of 204 identified proteins. We found that rainbow trout spermatozoa are equipped with functionally diverse proteins related to energetic metabolism, signal transduction, protein turnover, transport, cytoskeleton, oxidative injures and stress and reproduction. The availability of a catalogue of rainbow trout sperm proteins provides a crucial tool for the understanding of fundamental molecular processes in fish spermatozoa for ongoing research in the development of novel markers of sperm quality and for the optimization of short- and long-term sperm preservation procedures.

Project description:Successful production of aquaculture species depends on efficient growth with low susceptibility to disease. Therefore, selection programs have focused on rapid growth combined with disease resistance. However, chronic immune stimulation diminishes muscle growth (a syndrome referred to as cachexia), and decreases growth efficiency in production animals, including rainbow trout. In mammals, recent results show that increased levels of pro-inflammatory cytokines, such as those seen during an immune assault, specifically target myosin and MyoD and inhibit muscle growth. This suggests that increased disease resistance in fish, a desired trait for production, may actually decrease the growth of muscle, the main aquacultural commodity. To test this possibility, a rainbow trout model of cachexia was developed and characterized. A six-week study was conducted in which rainbow trout were chronically immune stimulated by repeated injections of LPS. Growth indices were monitored, and whole body and muscle proximate analyses, real-time PCR, and immunohistochemistry were conducted to examine the resulting cachectic phenotype. Muscle ratio was decreased in fish chronically immunostimulated, however expression levels of MyoD2 and myosin were not decreased compared to fish that were not immunostimulated, indicating that while muscle accretion was altered, the mechanism by which it occurred was somewhat different than that characterized in mammals. Microarray analysis was used to compare gene expression in fish that had been chronically immunostimulated versus those that had not to identify possible alternative mechanisms of cachexia in fish.
