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 highly sensitive to high-temperature stress as an important economic cold-water fish. While previous research has concentrated on the transcriptomic to acute heat stress in rainbow trout, there remains a gap in knowledge regarding the overarching regulatory mechanisms at the translation level. In our research, we utilized a combination of transcriptomic and translatomic analyses to investigate the intricate molecular response mechanisms in the liver of rainbow trout when subjected to heat stress. Through comprehensive multi-omics analysis, we revealed the dynamic translational pattern of rainbow trout liver under heat stress for the first time. Comparative analysis of ribosome analysis data with RNA-seq data showed that the fold changes of gene expression at the transcriptional level were highly correlated (R2 = 0.83) with those at the translational level globally. In total, 2,203 genes exhibited significant alterations exclusively within the translational level. However, the limited overlap in response genes between transcription and translation under heat stress suggests that these two processes may independently modulate the cellular response to thermal challenges. Significant changes in the translation efficiency of 809 genes were observed under heat stress. Further analysis indicated that the translation efficiency of genes were strongly influenced by sequence characteristics such as GC content, coding sequence length and NMFE. Moreover, 3,468 putative uORFs were identified in 2,676 genes, which potentially modulating translation efficiency of mORFs. These findings provide a novel perspective for understanding the physiological adaptations of rainbow trout in response to changes in ambient temperature.

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:The characterization of fish blood proteomes is important for the comparative studies of seminal and blood proteins as well as for the analysis of fish immune mechanisms and pathways. In this study LC-MS/MS and 2D DIGE was applied to compare seminal and blood plasma trout proteomes. The 54 differentially abundant proteins identified in seminal plasma are involved in a variety of signaling pathways, including protein ubiqutination, liver X receptor/retinoid X receptor (LXR/RXR) and farnesoid X (FXR)/RXR activation, cell cycle and acute phase signaling. These finding may indicate the prevalence of acute phase signaling pathways in trout seminal plasma, and its essential role in protecting spermatozoa and reproductive tissues. Furthermore our study provides the first in-depth analysis of the rainbow trout blood plasma proteome, with a total of 119 identified proteins. The major proteins of rainbow trout blood plasma were recognized as acute phase proteins. The Ingenuity Pathway Analysis of trout BP plasma proteins indicated that acute phase response signaling, complement system, LXR, FXR-RXR activation and coagulation system are the top canonical pathways associated with trout blood proteins. In conclusion this study enhances the knowledge of the blood origin of trout seminal plasma proteins and the understanding of fish reproductive biology. Additionally our results provide new insight into blood proteins specifically important for fish physiology and innate immunity.

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:Infectious hematopoietic necrosis virus (IHNV) can cause widespread death of rainbow trout (Oncorhynchus mykiss), understanding the molecular mechanisms that occur in the rainbow trout in response to IHNV infection will be useful to decrease IHN-related morbidity and mortality in trout aquaculture. However, the molecular mechanisms of rainbow trout in response to IHNV are very limited. This study performed analysis of mRNAs and miRNAs based on RNA-seq technology on the intestine of rainbow trout infected with IHNV and control. There were 80 differentially expressed miRNAs that regulated 3355 target mRNAs, which overlapped with differentially expressed mRNAs obtained from RNA-seq. The expression patterns of DEGs and miRNAs differentially expressed were validated by qRT-PCR. GO enrichment and KEGG pathway analyses of the potential target genes of the DE miRNAs, revealed DEGs were mainly enriched in immune-related pathways such as Toll-like receptor signaling pathway, RIG-I-like receptor signaling pathway and IL-17 signaling pathway. These findings improve our understanding of the molecular mechanisms of IHNV infection. The study analyzed the immune regulatory target gene pairs and signal pathways of rainbow trout intestine against IHNV infection at the transcriptional level, and provided basic data for the study of rainbow trout against IHNV immune regulatory.
