Project description:Oral immunization of trout against infectious pancreatic necrosis virus (IPNV) have been recently reported by using a DNA vector coding the viral capsid VP2 gene encapsulated in alginate microspheres. We report here an study of the transcripts in head kidney and pyloric ceca 7 days after oral vaccination of rainbow trout by using a newly designed rainbow trout 60-mer oligo microarray focused in their immune-related genes. Trout were obtained from 4 different farms, one group of trout was defined as belonging to one of the farms. Each of the trout 4 groups were divided into two subgroups of 6 trout for each subgroup. Subgroup I was orally vaccinated with 10 M-BM-5l of suspension of the vaccine microspheres each containing 10 M-BM-5g of pcDNA-VP2 diluted in 10M-BM-5l of PBS, while subgroup II received similar microspheres suspension but pcDNA. Head kidney and pyloric ceca were collected from each subgroup and RNA was extracted.

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.

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:Rainbow trout (Oncorhynchus mykiss) is an important cold-water fish widely cultivated in China. The frequent occurrence of viral diseases caused by infectious hematopoietic necrosis virus (IHNV) seriously restricted the healthy development of the rainbow trout farming industry. However, the immune defense mechanism induced by IHNV in rainbow trout has not been fully elucidated. In the present study, we detected mRNA and miRNA expression profiles in rainbow trout head kidney after IHNV infection and the expression patterns of key immune-related genes at different post-infection periods (0-, 6-, 12-, 24-, 48-, 72-, 96-, 120- and 144 hours post-infection (hpi)) using RNA-seq and qRT-PCR. The results showed that a total of 7486 genes and 277 miRNAs were differentially expressed, and numerous differentially expressed genes (DEGs) enriched in the immune-related pathways such as Toll-like receptor signaling pathway, RIG-I-like receptor signaling pathway, NOD-like receptor signaling pathway, cytokine-cytokine receptor interaction and JAK-STAT signaling pathway were significantly up-regulated, including LGP2, MDA5, TRIM25, IRF3, IRF7, TLR3, TLR7, TLR8, MYD88, IFN1, MX1 and VIG-1. Integration analysis identified six miRNAs (miR-141-y, miR-200-y, miR-144-y, miR-2188-y, miR-725-y and miR-203-y) that target at least four key immune-related genes (TRIM25, LGP2, TLR3, TLR7, IRF3 and IRF7). Expression analysis showed that TRIM25, MDA5, LGP2, TLR3, TLR7, IRF3, IRF7, IFN1, MX1 and VIG-1 genes increased firstly and then decreased, and reached peak expression at 48 hpi. These findings improve our understanding of the immune mechanism of rainbow trout infected with IHNV, and provide a basic data for future breeding for disease resistance in rainbow trout.

Project description:Rainbow trout (Oncorhynchus mykiss), an economically important cold-water fish cultured worldwide, suffers from infectious hematopoietic necrosis virus (IHNV) infection, resulting in huge financial losses. In order to understand the immune response of rainbow trout during virus infection, we explored trout skin transcriptome profiles following IHNV challenge, and identified 6905 differentially expressed genes (DEGs). Transcriptome analysis revealed numerous DEGs involved in immune responses, such as NOD1, NLRC3, NLRC5, TLR3, TLR7/8, TRIM25, DHX58, IFIH1, IRF3/7, STAT1, TRAF3, MX1 and HSP90A1. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses showed that DEGs were significantly enriched in various immune-related terms including immune system process, innate immune response and regulation of immune effector process and pathways of cytokine-cytokine receptor interactions, NOD-like receptor signaling, RIG-I-like receptor signaling, Toll-like receptor signaling, JAK-STAT signaling, Chemokine signaling pathway, and TNF signaling pathway. In addition, protein-protein interaction network (PPI) was used to display highly interactive DEG networks involving immune-related pathways. The expression trends of 16 DEGs were further verified by quantitative real-time PCR, which confirmed the reliability of the transcriptome sequencing results. This study expands our understanding of the immune response of rainbow trout infected with IHNV, and provides valuable resources for future studies on the immune molecular mechanism and disease resistance breeding.

Project description:Rainbow trout (Oncorhynchus mykiss) is one of the economically important cold-water fish cultivated in the world. The outbreak of infectious hematopoietic necrosis (IHN) seriously restricted the development of rainbow trout farming industry and caused huge economic losses. Fish skin is the largest mucosal immune organ, providing the first line of defense against pathogen invasion. However, the immune mechanisms associated with fish skin remain unclear. To systematically identify skin mucosal immune genes induced by infectious hematopoietic necrosis virus (IHNV) infection, trout transcriptome profiles following IHNV challenge were examined. Transcriptome analysis identified 6905 differentially expressed genes (DEGs) and revealed numerous immune-related DEGs involved in cytokine-cytokine receptor interactions, NOD-like receptor signaling, RIG-I-like receptor signaling, Toll-like receptor signaling, JAK-STAT signaling, Chemokine signaling pathway, and TNF signaling pathway, and the expression of these DEGs was significantly up-regulated in T48Skm group, including NOD1, NLRC3, NLRC5, TLR3, TLR7/8, TRIM25, DHX58, IFIH1, IRF3/7, STAT1, TRAF3, MX1, and HSP90A1. Additionally, highly interactive DEGs network involving immune-related terms and pathways was shown using protein-protein interaction network. The expression patterns of 12 DEGs were further verified by quantitative real-time PCR, which confirmed the reproducibility and reliability of transcriptome sequencing data. These findings expand our understanding of the innate immune system of rainbow trout skin infected with IHNV, and lay a foundation for further studies of the immune molecular mechanism and disease resistance breeding.
