Shotgun proteomic profiling of intestinal mucosa of rainbow trout Oncorhynchus mykiss

ABSTRACT: The objective of this study was to identify and quantify proteomic profiles of intestine 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 aquaria. The test groups were infected by immersion of Yersinia ruckeri CSF007-82 (biotype 1) and 7959-11 (biotype 2) strains. The control group was immersed similar with sterile broth medium. Fish were anaesthetized and sampled aseptically at different time points. Each intestine was washed three times with sterile phosphate-buffered saline containing a cocktail of mammalian protease inhibitors. Intestinal mucosa was scraped with a sterile large scalpel blade. Intestinal samples were snap-frozen in liquid nitrogen and stored at –80 °C.

Yersinia ruckeri is the causative agent of enteric redmouth disease in salmonids. In fish, the intestine represents an important site of nutrient uptake, host-pathogen interactions, and defense. The posterior intestine can be inflamed, reddened, and filled with an opaque, yellowish fluid during Y. ruckeri infection. Herein, we report an investigation on the proteome alteration in the posterior intestinal mucosa of rainbow trout (Oncorhynchus mykiss) after exposure to Y. ruckeri. The intestinal m ...[more]

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.
