CGH analyses for the Chinese indigenous pig breeds and commercial pig breeds [Agilent]

ABSTRACT: Since CNVs play a vital role in genomic studies, it is an imperative need to develop a comprehensive, more accurate and higher resolution porcine CNV map with practical significance in follow-up CNV functional analyses To detect CNV of pigs, we performed high density aCGH data of diverse pig breeds in the framework of the pig draft genome sequence (Sscrofa10.2) 9 Chinese indigenous pig, one Chinese wild boar and 2 commercial pigs were detected using one pig of Duroc as reference. These 12 animals include 1 wild pig, 2 pigs each from Yorkshire and Landrace as the representatives of modern commercial breeds and 9 unrelated individuals selected from 6 Chinese indigenous breeds (2- Tibetan pig, 2- Diannan small-ear pig, 2-Meishan pig, 1- Min pig, 1-Daweizi pig, and 1-Rongchang pig).

As a major component of genomic variation, copy number variations (CNVs) are considered as promising markers for some phenotypic and economically important traits in domestic animals. Using a custom-designed 1M array CGH (aCGH), we performed CNV discovery in 12 pig samples from one Asian wild boar population, six Chinese indigenous breeds, and two European commercial breeds. In total, we identified 758 CNV regions (CNVRs), covering 47.43 Mb of the pig genome sequence. Of the total porcine genes, ...[more]

SNP genotyping analyses for the Chinese indigenous pig breeds and commercial pig breeds

Project description:Genome-wide SNP genotyping array can genotyped SNP highthroughly. It can be used in many aspects, such as phylogeny relationships, genome-wide association studies, copy number identification. 9 Chinese indigenous pig, 4 commercial pigs and 1 wild pig were genotyped by PorcineSNP60 array (Illumina) for exploring the phylogeny relationships among them.

miRNA-seq of lung in two kinds of pig breeds after PCV2 injection

Project description:Postweaning multisystemic wasting syndrome in pigs has devastated the swine industry since the 1990s. Porcine circovirus type 2 (PCV2) is the primary cause of this disease. MicroRNAs (miRNAs) are small noncoding RNAs that play important roles in regulating gene expression, especially at the post-transcription level. The expression profiles of miRNAs have been reported in porcine reproductive and respiratory syndrome, porcine parvovirus, and other pig diseases; however, the miRNA expression profiles in pigs infected with PCV2 have not been reported so far. The Laiwu pig (a Chinese indigenous pig breed) has different meat quality, adipogenesis, and disease-resistance from western commercial pig breeds. In this study, four small RNA libraries were constructed from the lung tissue of uninfected and infected Laiwu and Yorkshire/Landrace crossbred (YL) pigs. High-throughput sequencing and bioinformatics were used to determine the abundance and differential expression of miRNAs in the four libraries

Identification of global copy number variations among diverse pig breeds by a CGH array

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 (♂).

An atlas of mRNA expression in pig adipose and muscle tissues

Project description:Obese and lean-type pig breeds show obvious differences in adipose deposition and muscle growth; however, the molecular mechanisms underlying this phenotypic variation remains unclear. Landrace (a leaner, Western breed), Rongchang (a fatty, Chinese breed) and Tibetan (a feral, indigenous Chinese breed that has not undergone artificial selection) pig breeds were used in this study. We collected eight diverse adipose tissues and two phenotypically distinct skeletal muscle tissues from three well-defined pig models with distinct fat rates, and studied mRNA expression differences among breeds, males and females, and tissues. These results highlight some possible candidate genes for porcine adipose deposition and muscle growth and provide some data on which to base further studies of the molecular basis of energy metabolism. The mRNA expression differences of eight diverse adipose tissues and two phenotypically distinct skeletal muscle tissues from three well-defined pig models with distinct fat rates are measured.
