Project description:The aim of this study was to gain a principal understanding of alterations within the transcriptome, spliceosome and editome in the pituitary of the domestic pig (Sus scrofa domestica L.), which controls basic physiological processes in the reproductive system, during early pregnancy. In this investigation, we performed extensive analyses of data obtained by high-throughput sequencing of RNA from the gilts' pituitary anterior lobes during embryo implantation and the mid-luteal phase of the estrous cycle, as a stage of the cycle with similar corpus luteum secretory activity to gestation.

Project description:For gaining additional insights into the composition of the testicular proteome of the domestic pig (Sus scrofa domestica), we conducted 2DE-MS. Two-dimensional SDS PAGE was run on testicular lysates of three boars, with three gels per boar. Upon matching across gels, we arbitrarily selected protein spots for mass spectrometry analysis. Excised slices were vacuum dried and soaked with digestion buffer containing trypsin (0.01 μg/μl), followed by overnight incubation at 37°C in the same buffer without trypsin. Subsequently, peptides were extracted in solvents of increasing acetonitrile content, by sonication. Upon vacuum-centrifugation, peptides were reconstituted in 0.1% formic acid (FA). Following this, peptides were fractionated by reversed phase liquid chromatography (C18; buffer A: 0.1% FA dissolved in HPLC-H2O; buffer B: 0.1% FA, dissolved in CAN; flow-rate: 0.4 µL/min; gradient: 2-30% in 30 minutes). Eluted peptides were injected via an electrospray ionization interface into a Q-TOF mass spectrometer (one boar, Q TOF Ultima, Micromass/Waters, Manchester, UK) and an ion-trap mass spectrometer (two other boars, XCT ion-trap, Agilent Technologies, Waldbronn, Germany). We used ProteomeDiscoverer 2.4 (Thermo Fisher Scientific, San Jose, USA) for peptide and protein identification. Using Sequest HT, we searched peak lists (*.mgf) against the Sus scrofa reference proteome database (UniProt Proteome ID: UP000008227, 49,793 proteins).

Project description:Recents studies in mammalian genomes have uncovered the extent of copy number variation (CNV) that contributes to phenotypic diversity, including health and disease status. Here we report the first glimpse of CNVs in the pig genome covering part of the chromosomes 4, 7, 14 and 17 already sequenced and assembled. We used a custom tiling oligonucleotide array with a median probe spacing of 409 bp to screen 12 unrelated Duroc boar founders of a vast-family material. After a strict CNV calling pipeline it was identified 40 copy number variable regions covering all the four chromosomes, with some overlapping segmental duplications and pig unigenes. This CNV snapshot analysis lays the groundwork for a better understanding of porcine phenotypes and genotypes for the identification of important economic traits. Keywords: comparative genome hybridization, CNV, Sus Scrofa, Nimblegen tiling array A custom 385k tiling-path array CGH was designed (Nimblegen Systems) to cover the preliminary Sus Scrofa assembly for chromosomes 4, 7, 14 and 17, from the August 2007 release (http://www.sanger.ac.uk/Projects/S_scrofa/), which was the newest version at the time of the experiment. From a pig family-material comprising 14 boar founders, 700 sows and about 12.000 offspring, 12 Duroc boar founders (A, B, C, D, E, G, H, J, K, L, M and N) were selected to function as test animals. An unrelated boar of the Hampshire breed was selected as the common reference. Each of the 12 boars were hybridized twice (technical replicates, 24 arrays) against the common reference.

Project description:All-genome genotyping data from French wild boar populations could be useful for diversity studies in the wild boar species as well as for phylogeny studies with domestic pig populations. The data produced in this experiment concern 362 wild boars collected between 2013 and 2019 in various French departments. The biological samples that were collected were either blood samples or ear biopsies. Genomic DNA was extracted from cells after proteinase K lysis and ethanol precipitation. DNA was hybridized on the GeneSeek Genomic Profiler porcine beadchip (GGP70K HD Porcine Illumina) using Infinium technology. Fluorescence intensity data obtained for each Single Nucleotide Polymorphism were analyzed with GenomeStudio software to infer genotypes. In addition, the raw fluorescence data could be useful for Copy Number Variation studies.

Project description:Porcine 60K BeadChip genotyping arrays (Illumina) are increasingly being applied in pig genomics to validate SNPs identified by re-sequencing or assembly-versus-assembly method. Here we report that more than 98% SNPs identified from the porcine 60K BeadChip genotyping array (Illumina) were consistent with the SNPs identified from the assembly-based method. This result demonstrates that whole-genome de novo assembly is a reliable approach to deriving accurate maps of SNPs. To compare SNPs identified by genotyping arrays and de novo assembly method, we genotyped 10 pig breeds by porcine 60K BeadChip genotyping array (Illumina), including 1 berkshire pig, 1 hampshire pig, 1 landrace pig, 1 large white pig,1 piétrain pig, 1 bamei pig,1 jinhua pig, 1 meishan pig, 1 rongchang pig and 1 Tibetan wild boar.

Project description:Domestication caused significant differences in morphology and behavior between wild and domestic animals, and gene expression changes played an important role in this event. circRNA is a class of non-coding RNA that exerts a wide range of functions in biological processes through the regulation of gene expression. However, the regulatory role of circRNA in the process of domestication is still unclear. Here, we analyzed circRNA expression patterns in the prefrontal cortices of wild boar and domestic pig to determine the potential role of circRNAs in domestication. We identified a total of 11,375 circRNAs and found that 349 and 354 circRNAs were up-regulated in wild boar and Rongchang pig, respectively. This study lays the groundwork for exploring the regulatory role of circRNA in the process of domestication and provides new insights that contribute to further investigation of the molecular mechanism of pig domestication.

Project description:Long non-coding RNAs (lncRNAs) play important roles in diverse biological processes. However, the landscape of lncRNAs is largely unclear in Sus scrofa. Here we performed stranded RNA-seq on total RNA libraries from over 100 samples of Sus scrofa tissues. We identified 10,813 lncRNAs in Sus scrofa, of which 9,075 are novel. 57% of these lncRNAs were conserved in both human and mouse. These conserved lncRNAs tend to be more tissue-specific than pig-specific lncRNAs, and enriched in reproducible organs (i.e. testis and ovary). We characterized a group of lncRNAs potentially involved in the skeletal muscle development. One such lncRNA, a homolog of maternally expressed gene 3 (MEG3), was specifically expressed in the skeletal muscle at early developmental stage. And its expression pattern is conserved in pig and mouse. By over-expressing and knocking down MEG3 in mouse myoblast cell lines, we demonstrated its novel function as a myoblast proliferation suppressor.
