ABSTRACT: Gene expression data of micro RNA from skeletal muscle sample of pig breed Duroc and Pietrain with malignant hyperthermia syndrome homozygous negative
Project description:Expression profiles of porcine muscle Semimembranosus were studied to identify genes beeing significantly affected by pre-slaughter stress or no stress treatment in pigs of different breed (Italian Duroc, Italian Large White or Pietrain) and differnt Halothane genotype (RYR1 locus CC-NN, CT-Nn or TT-nn) in Pietrain pigs.
Project description:47,880 probe-sets were screened, in the first part of this study, they were analysed for differential expression between different breeds (Duroc and Pietrain) at adult stage. RNAs of skeletal muscle from Duroc and Pietrain at adult stage were hybridized to Affymetrix Porcine Snowball Array.
Project description:Investigation of the transcriptome profile of lung dendritic cells (DCs) of two genetically different pig breeds (Pietrain and Duroc) after PRRSV infection in vitro and determination of the temporal changes in transcriptional profiles.
Project description:A CNV map in pigs could facilitate the identification of chromosomal regions that segregate for important economic and disease phenotypes. The goal of this study was to identify CNV regions (CNVRs) in pigs based on a custom array comparative genome hybridization (aCGH). We carried out a custom-made array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the pig genome analysing animals of diverse pig breeds (White Duroc, Yangxin, Erhualian, Tongcheng, Large White, Pietrain, Landrace and Chinese new pig line DIV ) using a tiling oligonucleotide array with ~720,000 probes designed on the pig genome (Sus scrofa genome version 9.0). In this study, a custom-made tiling oligo-nucleotide 720k array was used with a median probe spacing of 2506 bp for screening 12 pigs with a female Duroc as the reference. WD: White Duroc (♀); YX: Yangxin (♂); EH: Erhualian (♀); TC: Tongcheng (♀); LW: Large White (♀); PT: Pietrain (♂); LD1: Landrace × DIV pig 1 (♂); LD2: Landrace × DIV pig 2 (♀); DIV1: Chinese new pig line DIV 1 (♀); DIV2: Chinese new pig line DIV 2 (♀); L1: Landrace 1 (♂); L2: Landrace 2 (♂).
Project description:Genetic variability of transcript abundance in pig skeletal muscle at slaughtering. The 325 pigs (females and barrows) used in gene expression analyses are part of a larger F2 population of 1,000 animals, setup within the framework of a QTL detection program. These animals were produced as a second generation intercross between two commercial sire lines (F016, Pietrain type line, and FH019, synthetic line from Hampshire, Duroc and Large-White founders, FRANCE-HYBRIDES, St Jean de Braye, France).
Project description:Transcriptional profiling between two different skeletal muscles (Longissimus and Semimembranosus) in pig The 90 pigs (females and barrows) used in gene expression analyses are part of a larger F2 population of 1,000 animals, setup within the framework of a QTL detection program. These animals were produced as a second generation intercross between two commercial sire lines (F016, Pietrain type line, and FH019, synthetic line from Hampshire, Duroc and Large-White founders, FRANCE-HYBRIDES, St Jean de Braye, France).
Project description:Expression profiles of porcine muscle Semimembranosus were studied to identify genes beeing significantly affected by pre-slaughter stress or no stress treatment in pigs of different breed (Italian Duroc, Italian Large White or Pietrain) and differnt Halothane genotype (RYR1 locus CC-NN, CT-Nn or TT-nn) in Pietrain pigs. All 36 samples were hybridised together with a common reference.
Project description:Pig breeds have different attitude to traits like growth rate, carcass composition and reproduction parameters as well as other traits. These traits considered as external traits or end phenotypes are the outcome of complex biological processes and interactions. The main goal of pig breeding programs and the basis for crossbreeding is finding a balance between these traits. In pig production, Large White and Duroc breeds are commonly used to optimise respectively fertility and growth ability and differ on several production traits, indeed the first breed as a high fertility characters whereas Duroc is used as terminal sire for her growth performance and good carcass quality traits. In this study, we have used a quantitative label-free LC-MS proteomics approach to characterise and compare the liver proteome of two heavy Italian pig breeds, Italian Duroc and Italian Large White to identify difference due to their different genetic background. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 703094.
