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: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:Brucella suis infects macrophages and dendritic cells. Wild boars act as reservoirs and carriers of Brucella suis biovar 2, and there is evidence that wild boar can be the main source of infection for domestic pigs through the venereal route. Transmission through this route could be an important path for disesease dissemination. The result from this study will contribute to the overall understanding of the molecular pathogenic mechanisms involved during Brucella suis infection in European wild boar.
Project description:We identified 34,521 and 31,803 circRNAs in piglet (30 d) and adult (210 d) boar testis by high-throughput sequencing, respectively. Bioinformatics analysis revealed that these circRNAs are widely distributed on autosomes and sex chromosomes. Some of the host genes can generate multiple circRNAs. A total of 2,326 differentially expressed circRNAs (DECs) derived from 1,526 host genes were found in testicular development, of which 1,003 circRNAs were up-regulated in adult boar testes and 1,323 circRNAs were down-regulated. Furthermore, gene ontology (GO) analysis of host genes of DECs revealed that these circRNAs are mainly involved in regulating spermatogenesis, cilia motility, and hormone biosynthesis. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that the DECs are markedly enriched to stem cell pluripotency regulation, tight junctions, adhesion junctions, and cAMP signaling pathway. These results indicate that circRNAs are abundantly expressed in boar testes and exhibit dynamic changes during testicular development.
Project description:To evaluate the roles of miRNA in porcine liver, dynamic profiles of microRNAome were investigated in swine breeds with different traits of commercial interest, we sampled liver tissues from a Chinese well-known elite native breed of Enshi black pig, a Large White pig, and a Chinese wild boar living within the same environment at the same day-old(90d).

The result from this study will contribute to the overall understanding of the molecular pathogenic mechanisms involved during Brucella suis infection in European wild boar. Experiment Overall Design: In this study we preliminarily characterized differential gene expression in European wild boar naturally infected with Brucella suis biovar 2 using Microarray hybridization and Real Time RT-PCR analysis. Since Brucella suis acts by infecting macrophages, we used spleen cells to analyze the gene expression response to Brucella suis infection.
