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:The rainbow trout (Oncorhynchus mykiss) is one of the most important aquaculture species worlwide. In this study, transcriptional profiling of skin by oligonucleotide microarray was applied to rainbow trout individuals infected with A. salmonicida, to identified enriched genes involved in pathogen response.

Project description:In the present study the combination of protein fractionation by one-dimensional gel electrophoresis and high performance liquid chromatography electrospray ionization tandem mass spectrometry was used to characterize the rainbow trout seminal plasma proteome. Our results led to the creation of a catalogue of rainbow trout seminal plasma proteins and significantly contributed to the current knowledge regarding the protein composition of fish seminal plasma. The major proteins of rainbow trout seminal plasma, such as transferrin, apolipoproteins, complement C3, serum albumin, hemopexin-like protein, alpha-1-antiproteinase-like and precerebellin-like protein were recognized as acute phase proteins (proteins which plasma concentration changes in response to inflammation). This study provides the basis for further functional studies of fish seminal plasma proteins, as well as for the identification of novel biomarkers for sperm quality.

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.

Project description:The mechanisms of cardiotoxicity of the three widespread model polycyclic aromatic hydrocarbons (PAHs) retene, pyrene and phenanthrene were explored in rainbow trout (Oncorhyncus mykiss) early life stages. Newly hatched larvae were exposed to sublethal doses of each individual PAH causing no detectable morphometric alterations. Changes in the cardiac proteome were assessed after 7 or 14 days of exposure to each PAH.

Project description:Rainbow trout (Oncorhynchus mykiss) is an important aquaculture fish species that is farmed worldwide, and it is also the most widely cultivated cold water fish in China. This species, a member of the salmonidae family, is an ideal model organism for studying the immune system in fish. Two phenotypes of rainbow trout are widely cultured; wild-type rainbow trout with black skin (WR_S) and yellow mutant rainbow trout with yellow skin (YR_S). Fish skin is an important immune organ, however, little is known about the differences in skin immunity between WR_S and YR_S in a natural flowing water pond aquaculture environment, and very few studies were conducted to investigate the ceRNA mechanism for fish skin.

Project description:The study aimed to characterize gene expression in rainbow trout ovary during ovarian development from immature to mature stages. Whole ovary were collected at the following stages: immature pre-vitelogenesis (IMM), mid-vitellogenesis (MV), late vitellogenesis (LV), post-vitellogenesis (PV) and mature while meiotic maturation is in progress (MAT). Gene expression in rainbow trout ovary was measured at 5 different stages (immature, mid-vitellogenesis, late vitellogenesis, post-vitellogenesis and mature). Three to four biological replicates were used for each stages.
