Project description:Yellow mutant rainbow trout (YR) is becoming more popular for aquaculture production in China in recent years owing to its excellent meat quality and gorgeous appearance. Although much comparative research has been undertaken on two or three different skin colors of the same species, seldom attentions were focused on the genetic regulation during the developmental process of pigmentation. In this study, the skin transcriptomes in three distinct developmental stages of YR were sequenced to search for genes related to skin pigmentation.

Project description:As an important cold-water economic fish species, rainbow trout (Oncorhynchus mykiss) exhibits several intra-specific variation in skin pigmentation that can give rise to distinctive phenotypes, and wild-type rainbow trout with black skin (WR) and yellow mutant rainbow trout with yellow skin (YR) are the major two types in the farms, whose distinct skin colors make them suitable model for elucidating the skin pigmentation process. Skin color as a key indicator for selection in rainbow trout farming as well as has a strong visual impact on the consumer when rainbow trout are marketed. Previously, extensive studies have been conducted on skin color in rainbow trout, including the observation of skin spots and the expression analysis of some important pigment genes. However, up to date, no studies have systematically examined the molecular regulation mechanism of skin color difference between WR and YR through a high throughput method. Therefore, the aim of this study was to reveal the molecular regulation mechanism of skin color difference between these two strains at the mRNA and miRNA transcriptome level, and candidate genes, miRNAs and miRNA-mRNA pairs that may be responsible for rainbow trout albinism were obtained.

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:Rainbow trout (Oncorhynchus mykiss) is a well-known economical fish globally, and its market value and acceptance are greatly influenced by skin color. However, the molecular mechanisms underlying skin color variation in rainbow trout remains largely unknown. In this study, we compared the expression profiles of whole transcriptome in dorsal skin from wild-type (WTrt) and yellow mutant rainbow trout (YMrt) that are F1 generation of WTrt ♂ × YMrt ♀. A total of 115 differentially expressed (DE) mRNAs, 126 lncRNAs, 18 circRNAs and 56 miRNAs were identified, and several core genes (gch1, pts, slc2all, pax7a/pax7b, dgat2, plin6 and pnpla2) involved in pteridine and carotenoid synthesis were significantly upregulated in YMrt. Interestingly, we found that melanogenesis-related genes tyr, dct, mitfa and pmel were also notably elevated in YMrt. Functional enrichment analysis revealed some pigmentation-related GO terms and KEGG pathways, including pteridine-containing compound biosynthetic process, pigment metabolic process, melanosome, melanosome transport, tyrosine metabolism and melanogenesis. Based on competing endogenous RNA analysis, there were 25 and 21 lncRNA-miRNA-mRNA networks targeted to gch1 and mitfa, such as LOC110496571-miR-96-x-gch1, LOC110508587- miR-182-x-gch1, LOC110494316-miR-21-y-mitfa and LOC110526055- miR-182-x-mitfa. Additionally, one (novel_circ_000056), eight (including novel_circ_005436 and novel_circ_005586) and three circRNAs (novel_circ_000382, novel_circ_002592 and novel_circ_005868) were found to regulate dgat2, gch1 and mitfa by targeting 21 miRNAs. This study provides a systematic perspective on the potential functions of these DEmRNAs and ncRNAs, and lays a foundation for further study on the molecular mechanisms governing rainbow trout skin color variation.

Project description:Purpose: The goal of this study is to identify the difference of immunity between wild-type and yellow mutant rainbow trout in natural flowing water pond culture environment. Methods: The transcriptomic profiles of the skin were generated by using the Hiseq™4000 sequencing platform. Results: A total of 557,976,332 clean reads were yielded from six libraries and then assembled into 38,226 genes. Using P-value of 0.05 as the threshold, 3373 differentially expressed genes (DEGs) were obtained between WR_S and YR_S rainbow trout skin including the members of HSP90, V-ATPases, GST, SUGT1, NLRP3, NOD1, TLR3, IFR3, DHX58, IFIH1, JAK1, JAK2, STAT1 and NAMPT (|log2 fold-change| ranged from 1 to 4). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of DEGs were performed. A majority of DEGs were enriched in innate immune-related GO terms and pathways, such as activation of innate immune response, inflammatory response, innate immune response, NAD+ADP-ribosyltransferase activity and NAD biosynthetic process in sub-categories of GO terms, and RIG-I-like receptor signaling pathway, NOD-like receptor signaling pathway, Toll-like receptor signaling pathway, Phagosome, Jak-STAT signaling pathway in KEGG enrichment pathways. Meanwhile, several immune-related metabolic pathways were also identified including metabolism of Xenobiotics by cytochrome P450, Glutathione metabolism, Nicotinate and nicotinamide metabolism. Additionally, 15 DEGs were selected and validated their expression level by qRT-PCR to confirm accuracy of the RNA-seq. Conclusions: Our study is the first time to clarify the skin innate immunity difference between wild-type and yellow mutant rainbow trout in the natural flowing water pond culture environment. Our results show that the expression of most immune-related genes in the corresponding pathways were up-regulated in WR_S rainbow trout. We presumed that the disease resistance of WR_S rainbow trout might be stronger than YR_S rainbow trout.

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:Yellow mutant rainbow trout (YR), an economically important aquaculture species, is popular among consumers due to its excellent meat quality and attractive appearance. Skin color is a key economic trait for YR, but little is known about the molecular mechanism of skin color development. In this study, YR skin transcriptomes were analyzed to explore temporal expression patterns of pigmentation-related genes in three different stages of skin color development. In total, 16,590, 16,682, and 5619 genes were differentially expressed between fish at 1 day post-hatching (YR1d) and YR45d, YR1d and YR90d, and YR45d and YR90d. Numerous differentially expressed genes (DEGs) associated with pigmentation were identified, and almost all of them involved in pteridine and carotenoid synthesis were significantly upregulated in YR45d and YR90d compared to YR1d, including GCH1, PTS, QDPR, CSFIR1, SLC2A11, SCARB1, DGAT2, PNPLA2, APOD, and BCO2. Interestingly, many DEGs enriched in melanin synthesis pathways were also significantly upregulated, including melanogenesis (MITF, MC1R, SLC45A2, OCA2, and GPR143), tyrosine metabolism (TYR, TYRP1, and DCT), and MAPK signaling (KITA) pathways. Using short time-series expression miner, we identified eight differential gene expression pattern profiles, and DEGs in profile 7 were associated with skin pigmentation. Protein-protein interaction network analysis showed that two modules were related to xanthophores and melanophores. In addition, 1,812,329 simple sequence repeats and 2,011,334 single-nucleotide polymorphisms were discovered. The results enhance our understanding of the molecular mechanism underlying skin pigmentation in YR, and could accelerate the molecular breeding of fish species with valuable skin color traits and will likely be highly informative for developing new therapeutic approaches to treat pigmentation disorders and melanoma.

Project description:The sea-run phenotype of rainbow trout (Oncorhynchus mykiss), like other anadromous salmonids, present a juvenile stage fully adapted to life in freshwater known as parr. Development in freshwater is followed by the smolt stage, where preadaptations needed for seawater life are developed making fish ready to migrate to the ocean, after which event they become post-smolts. While these three life stages have been studied using a variety of approaches, proteomics has never been used for such purpose. The present study characterised the blood plasma proteome of parr, smolt and post-smolt rainbow trout using a gel electrophoresis liquid chromatography tandem mass spectrometry approach alone or in combination with low-abundant protein enrichment technology (combinatorial peptide ligand library). In total, 1,822 proteins were quantified, 17.95% of them being detected only in plasma post enrichment. Across all life stages, the most abundant proteins were ankyrin-2, DNA primase large subunit, actin, serum albumin, apolipoproteins, hemoglobin subunits, hemopexin-like proteins and complement C3. When comparing the different life stages, 17 proteins involved in mechanisms to cope with hyperosmotic stress and retinal changes, as well as the downregulation of nonessential processes in smolts, were significantly different between parr and smolt samples. On the other hand, 11 proteins related to increased growth in post-smolts, and also related to coping with hyperosmotic stress and to retinal changes, were significantly different between smolt and post-smolt samples. Overall, this study presents a series of proteins with the potential to complement current seawater-readiness assessment tests in rainbow trout, which can be measured non-lethally in an easily accessible biofluid. Furthermore, this study represents a first in-depth characterisation of the rainbow trout blood plasma proteome, having considered three life stages of the fish and used both fractionation alone or in combination with enrichment methods to increase protein detection.
