Project description:Background: Skeletal muscle growth and development is highly orchestrated in gene expressions. Understanding the location-specific and breed-specific genes and pathways are agriculturally important on meat products and meat quality. In the present study, RNA-Seq was performed to elucidate the difference of muscle deposition between locations and breeds for functional genomics studies. To achieve those goals, skeletal muscle samples were collected for pectoral muscle (PM) and leg muscle (LM) of two genetically different duck breeds, Heiwu duck (H) and Peking duck (P), at embryonic 15 days. Functional genomics studies were performed in two experiments: Experiment 1 directly compared location-specific genes between PM and LM, while Experiment 2 compared the two breeds (H and P) at the same development stage (embryonic 15 days). Results: Almost 13 million clean reads was generated using Illumina technology on each library, and more than 70% reads mapped to Anas platyrhynchos breed Peking duck genome. We identified 246, 258, 20 and 54 differentially expressed genes (DEGs) (log2.fold-change >0.5, and P-value <0.05) for H-PM vs H-LM, P-PM vs P-LM, H-LM vs P-LM and H-PM vs P-PM library, separately. A total of 168 genes were differentially expressed by over locations in experiment 1, while only 8 genes were differentially expressed by over breeds in experiment 2. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes pathways (KEGG) were used to functionally annotate DGEs. In experiment 1, DEGs mainly involved in Focal adhesion, PI3K-Akt signaling pathway and ECM-receptor interaction pathways (corrected P-value<0.05). In experiment 2, DEGs only associated with ribosome signal pathway (corrected P-value<0.05). In addition, quantitative real-time PCR was employed to confirm 15 differentially expressed genes detected by RNA-Seq. Conclusions: Comparative transcript analysis of leg muscle and pectoral muscle of two duck breeds not only improves our understanding of those location-specific and breed-specific genes and pathways, but also provides some candidate molecular targets for increase muscle products and meat quality by genetic control. Conclusions: Our study represents the first detailed analysis of duck breed muscle transcriptomes generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.

Project description:Muscle development and lipid deposition are complex processes regulated by a coordinated expression profile of genes. Pekin ducks displayed a significant difference from Cherry Valley duck in muscle fiber development and IMF contents. Genetic comparisons between these two breeds would contribute to the exploration of mechanisms underlying the phenotypic differences. In the present study, breast tissues of Pekin (BD) and Cherry Valley (CD) ducks were used for RNA-seq in two different time points (3 and 6-week) to investigate the transcriptome basis. A total of 16705 genes from duck breast muscle were detected as positively expressed genes (RPKM>0.1) and 2273 genes were regarded as novel genes. Differentially expressed genes (DEGs) in BD3 VS CD3 were regarded as muscle development-related genes as CD3 grown faster than BD3 in muscle fibers. DEGs in BD6 VS CD6 were regarded as lipid-related genes as a much higher IMF contents in BD6 than CD6 while no differences observed in 3-week. DEGs obtained from BD3 VS BD6 and CD3 VS CD6 were also analyzed as relative genes here. In all, 9 genes (MAT1A, KAZALD1, SHROOM3, KLHL6, MYH13, ALDOA, TNNT2, PDLIM3 and PFKM) were validated as muscle development correlated candidate genes, and another 11 genes (DHCR24, CNTFR, ANGPTL4, BCL6, HIP1, TRIB1, ADORA1, C1QTNF2, CD36, PRKAG2 and ACSL1) were regarded as lipid correlated genes in duck. What’s more, functional analysis confirmed that the immune reaction, ECM and energy metabolism also correlated with muscle development and lipid deposition closely. The present study not only enlarged the duck genetic information pool but also provided a dozen of candidate genes related to muscle development and lipid deposition, which laid a firm foundation for the further studies on molecular mechanisms in duck.

Project description:The growth and development of duck skeletal muscle is an important economic trait that is genetically regulated. The internal mechanism underlying the regulation of skeletal muscle growth and development in ducks remains unclear. The purpose of this study was to identify candidate genes related to growth of duck skeletal muscle. RNA-sequencing technology was used to com-pare the transcriptome of duck breast muscles in an F2 population with the high breast muscle rate (HB) and the low breast muscle rate (LB). A total of 14,522 genes were confirmed to be ex-pressed in the breast muscle, and 173 differentially expressed genes (DEGs) were identified be-tween the HB and LB groups. Functional analysis showed that these DEGs were mainly involved in biological processes and pathways of fat metabolism and muscle growth, especially the FABP3 and MYL4 involved in the PPAR signaling pathway and cardiac muscle contraction pathway. These findings deepened our understanding of the molecular mechanisms involved in muscle growth in ducks, and provided a theoretical basis for improving duck production and breeding of ducks.

Project description:The underlying molecular mechanisms of pathogenesis and outcome of disease to different pathotypes of H5N1 influenza infection in ducks remain unclear. For that, we studied genome wide host gene expression of lung tissues infected with A/duck/India/02CA10/2011(AD2011) H5N1 virus and A/duck/Tripura/103597/2008 (AD2008) H5N1 virus in ducks using custom designed microarray. AD2011 is highly pathogenic whereas AD2008 is low pathogenic to ducks. Comparative analysis of differentially expressed genes revealed that 688 genes were commonly expressed, 877 and 1556 genes are uniquely expressed to infection with AD2011 and AD2008 virus isolate, respectively. The up-regulation of cytokines genes OAS, IL1B, IL17, IFITM2, CCL4, CXCR4, STAT3, TGFB1 and TGFB2 in the lungs tissues may cause high mortality in ducks infected with AD2011 virus. The expression of important antiviral immune genes IFIT5, IFITM5, RSAD2, EIF2AK2 (PKR), Mx, β-defensins, TRIM23 and SLC16A3 to AD2008 infection, but not in AD2011 infection, cause the host may fine-tune their innate immune responses and prevent from cytokines storms and tissue damage. Several immune related Gene ontology (GO) terms and immune pathways activated were qualitatively similar but quantitatively different to both virus infections. Based on these findings, we conclude that subtle differences in host immune responses may determine the different outcome of H5N1 infection in ducks.

Project description:While infection of chickens with highly pathogenic avian influenza (HPAI) H5N1 subtypes often leads to complete mortality within 24 to 48 h, infection of ducks in contrast causes mild or no clinical signs. Rapid onsets of fatal disease in chickens, but with no evidence of severe clinical symptoms in ducks, suggest underlying differences in their innate immune mechanisms. To understand the molecular basis for such difference, chicken and duck primary lung cells, infected with a low-pathogenicity avian influenza (LPAI) and two HPAI H5N1 viruses, were subjected to RNA expression profiling using Affymetrix Chicken GeneChip arrays. We used microarrays to analyze the gene expression profiles of primary chicken and duck lung cells infected with H2N3 LPAI and two H5N1 influenza virus subtypes to understand the molecular basis of host susceptibility and resistance. We have identified a set of key genes and pathways that could play an important role in mediating innate host resistance to avian influenza in chickens and ducks.

Replicate RNA samples from each of the virus-infected (H2N3, H5N1 50-92, or H5N1 ty-Ty) or mock-infected chicken and duck cells (4 treatment groups for each species) were used for microarray analysis. Each of the RNA samples was hybridized to one GeneChipM-BM-. Chicken Genome Array (Affymetrix), and a total of 16 array chips were used.

Project description:Duck reovirus (DRV), a member of the genus Orthoreovirus in the family Reoviridae, was first isolated from Muscovy ducks. The disease associated with DRV causes great economic losses to the duck industry. However, the responses of duck (Cairna moschata) to the classical/novel DRV (C/NDRV) infections are largely unknown. To reveal the relationship of pathogenesis and immune response, the proteomes of duck spleen cells under the control and C/NDRV infections were compared. In total, 5986 proteins were identified, of which 5389 proteins were quantified. The different expressed proteins (DEPs) under the C/NDRV infections showed displayed various biological functions and diverse subcellular localizations. The proteins related to the serine protease system were siginificantly changed, suggesting that the activated serine protease system may play an important role under the C/NDRV infections. Furthermore, the differences in the responses to the C/NRDV infections between the duck liver and spleen cells were compared. Only a small number of common DEPs were identified in both liver and spleen cells, suggesting diversified pattern involved in the responses to the C/NRDV infections. However, the changes in the proteins involved in the serine protease systems were similar in both liver and spleen cells. Our data may give a comprehensive resource for investigating the responses to C/NDRV infections in ducks.

Project description:We aim to study the unusual TMA metabolism mechanism of ducks, and further explore the hidden reasons that led to the weakening TMA metabolism ability. To achieve this, transcriptome, proteome, and metagenome analyses were integrated based on the constructed duck populations with high TMA metabolism ability and low TMA metabolism ability. In addition, further experiments were followed to validate the hypothesis on the limited flavin-containing monooxygenase 3 (FMO3) metabolism ability of ducks. The study demonstrated that both cecal microbe, including Akkermansia and Mucispirillum, and liver FMO3 participated in the TMA metabolism process of ducks. The limited oxidation ability of FMO3 explained the weakening TMA metabolism ability of ducks. Nevertheless, it contributed to the duck’s survival and reproduction during the evolutional adaption process.

Project description:Purpose:To understand the transcriptome regulator of duck spleen infected with duck enteritis virus (DEV).Methods:50-day-old ducks were inoculated with 100 titer (The TCID50 of DEV was 10-9/0.1mL) and 10-2 titer two different viral titer of DEV in leg muscle for different durations (66 h, 90 h and 114 h) and seronegative control (0 h) were analyzed using next-generation RNA sequencing.Furthermore, the data were validated using quantitative real-time PCR.Results:There were 534, 685 and 580 genes differentially expressed in 100 titer, moreover, 511, 485 and 531 differentially expressed genes (DEGs) were obtained from 10-2 titer for 66 h, 90 h and 114 h, respectively. These genes were mainly involved in functional categories including immune response, extracellular space, heparin binding, oxygen transport, extracellular region, cellular response to interleukin-4, MHC class II protein complex, antigen processing and presentation of peptide or polysaccharide antigen via MHC class II, and pathways such as ribosome, ECM-receptor interaction, cell adhesion molecules, JAk-STAT signaling pathway, PPAR signaling pathway, neuroactive ligand-receptor interaction, phagosome.Conclusions: Different titers of DEV infection can stimulate different biological processes and signaling pathways in the spleen, and regulated the complex biological processes, metabolic and signaling pathways in the process of DEV infection.This transcriptome analysis of duck spleen infected with DEV in different time points is reported for the first time, it laid the foundation for further understanding of interactions between DEV and duck spleen tissue, molecular mechanisms of duck defend against DEV infection, and screening key functional genes.
