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: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:In this project we try to character potential candidate genes and signaling pathways related to PM development during late-term embryonic to neonatal development in indigenous chinese duck breeds. We use RNA-seq to analyse PM samples selected at embryonic days (E) 21 and 27 and 5 days post-hatch (dph) in Gaoyou and Jinding ducks. There were about 45 million clean reads, the total mapped rate was 58.58%–64.82%, and the uniquely mapped rate was 56.21%–63.55%.The results of cluster analysis of DEGs are shown that with the same developmental time nodes superimposed. There were 522 DEGs between Gaoyou and Jinding ducks at E21, including 146 novel genes. There were 299 DEGs and 81 novel genes at E27, and 510 DEGs and 118 novel genes at 5 dph. A total of 43 DEGs were shared by both breeds at all time points, including 19 novel genes.We further considered the 393 genes with expression patterns in line with the muscle development curve in both breeds. these DEGs may be involved in the mechanisms responsible for the phenomenon of static or decreased breast muscle growth in duck breeds during the late embryonic period.

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.

Project description:During cortical development neurons are generated sequentially from basal progenitors (BPs) which specifically express the transcription factor Tbr2. We used fluorescent-activaed cell sorting (FACS) to isolate BPs from Tbr2GFP knockin reporter mice (Arnold SJ et al. Genesis, 2009) at early (embryonic day, E13) and late (embryonic day, E16) stages of cortical neurogenesis and determined miRNA expression profiles using mouse miRNA microarray (Agilent).Comparison of E13 and E16 microRNA expression profiles allowed us to identify regulatory mechanisms for maintaining stage specific homeostasis of BPs.

Project description:The liver responsible for 90% lipid synthesis in poultry thus plays important role in the growth of Muscovy duck, which obtains high-fat deposition ability in a time-dependent manner. Therefore, male Muscovy ducks at the age of 14, 28, 42, and 56 days were selected for body weight (BW), carcass weight (CW), subcutaneous fat thickness (SFT), abdominal fat weight (AFW), intramuscular fat content (IMF), breast muscle fiber (BMF) diameter and density determination. Two-dimensional electrophoresis (2-DE) combined with liquid chromatography linked to tandem mass spectrometry (LC-MS/MS) was used to analyze the differentially expressed proteins in the liver at each stage.

Project description:Avian beaks show extreme species-specific variability in morphology, though they develop from the same primordial structures. In both humans and birds, cranial neural crest cells are the primary source of mesenchyme for the frontonasal prominence; previous work has shown that these cells contain molecular information that regulate species-specific facial variation. To determine the molecular basis of avian craniofacial patterning, we have gene expression profiled micro-dissected cranial neural crest cells from the frontonasal prominence of three bird species (chickens, quails, and ducks) during embryonic development. These changes in gene expression were measured on a custom built, cross-species, long oligonucleotide microarray that interrogates the vast majority of transcription factor (TF) genes plus a wide variety of signaling pathways. Samples were isolated at two developmental stages, before (Hamburger Hamilton stage [HH] 20) and after (HH25) morphological distinctions between the species are evident. Keywords: cross-species comparison Frontonasal mesenchymal cells were micro-dissected two developmental stages, before (Hamburger Hamilton stage [HH] 20) and after (HH25) morphological distinctions between the species are evident. For each sample, mesenchyme from 40 embryos was pooled. For each stage-matched comparison between duck and chicken, experiments include technical replicates as well as dye-switches for a total of 14 microarrays.
