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.

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:Crossbreeding has been an effective method to improve crossbred performance in pig industry. To have a global view of a classic three-way crossbreeding system of Duroc x (Landrace x Yorkshire) (DLY), we identified SNPs for each pig breed and crossbred individual originated from a DLY pig family to estimate the influence of purebreds on crossbred offspring using whole-genome sequencing. To confirm the accuracy of the SNPs identified by whole-genome sequencing, therefore, we performed the porcine 60K BeadChip genotyping array (Illumina) for each sequenced pig individual.

Project description:We performed a pooled GWAS and individual genotyping in 269 children with allergic respiratory diseases comparing allergic children with and without asthma. We used a modular approach to identify the most significant loci associated with asthma by combining silhouette statistics and physical distance method with cluster-adapted thresholding. We found 97% concordance between pooled GWAS and individual genotyping, with 36 out of 37 top-scoring SNPs significant at individual genotyping level. The most significant SNP is located inside the coding sequence of C5, an already identified asthma susceptibility gene, while the other loci regulate functions that are relevant to bronchial physiopathology, as immune- or inflammation-mediated mechanisms and airway smooth muscle contraction. Integration with gene expression data (from mouse experimental asthma model taken from GSE6858 and GSE1301) showed that almost half of the putative susceptibility genes are differentially expressed in experimental asthma mouse models.

Project description:A cell line (MFD-1) was derived from a 55-year old male with oesophageal adenocarcinoma. Using different sources of genetic material from normal and tumour tissue surgically resected, peripheral blood and the derived cell line a high concordance of genotypes calls across the whole genome confirms MFD-1 was derived from parent tumour. The SNP6 array contained 906,000 probes for the genotyping of SNPs and 946,000 probes for the genotyping of non-polymorphic copy number. Affymetrix CEL files were analysed using the tool PICNIC2 (predicting absolute allele copy number variation with microarray cancer data).

Project description:The pig is important for agriculture and as an animal model in human and veterinary medicine, yet, despite over 20 years of effort, it has proved a difficult species from which to generate pluripotent stem cells analogous to those derived from mouse embryos. Here we report the production of LIF-dependent, so called naïve type, pluripotent stem cells from the inner cell mass of porcine blastocysts by up-regulating expression of KLF4 and POU5F1. These cells resemble mouse ES cells and are distinct from the FGF2-dependent, induced pluripotent cell type derived from porcine somatic cells. High throughput SNP chip genotyping was conducted on Illumina's Porcine SNP60 BeadChip (WG-410, a service provided by Geneseek, NE, http://www.neogen.com/GeneSeek/). The results exhibited that the two lines pluripotent stem cells from the inner cell mass of porcine blastocysts were porcine origin and genetically distinct.

Project description:Genotyping arrays are tools for high throughput genotyping, which is required in genome-wide association studies (GWAS). Since the first cucumber genome draft was reported, genetic maps were constructed mainly based on simple-sequence repeats (SSRs) or on combinations of SSRs and other sequence-related amplified polymorphism (SRAP). In this study we developed the first cucumber genotyping array which consisted of 32,864 single nucleotide polymorphisms (SNPs). These markers cover the cucumber genome every 2.1Kb and have parents/F1 hybridizations as a training set. The training set was validated with Fludigm technology and had 98% concordance. The application of the genotyping array was illustrated by constructed a genetic map of 600 cM in length based on recombinant inbred lines (RIL) population of a 9930XGy14 cross of which compromise of 11564 SNPs. The markers collinearity between the genetic map and genome references of the two parents estimated as R2=0.97. Moreover, this comparison supports a translocation in the beginning of chromosome 5 that occurred in the lineage of 9930 and Gy14 as well as local variation in the recombination rate. We also used the array to investigate the local allele frequencies along the cucumber genome and found specific region with segregation distortions. We believe that the genotyping array together with the training set would be a powerful tool in applications such as quantitative-trait loci (QTL) analysis and GWAS.

Project description:A GWAS study was then performed in 52 non-adhesive and 68 strong adhesive pigs for F4ab/ac ETEC originating from 5 Belgian farms. A new refined candidate region (chr13: 144,810,100-144,993,222) for F4ac ETEC susceptibility was identified with MUC13 adjacent to the distal part of the region. All pigs were phenotyped for the presence of the F4ab/ac receptor (F4ab/acR) using the in vitro villous adhesion assay with 4×108 F4ac E. coli (strain GIS26, serotype O149:K91, F4ac+) or F4ab E. coli (strain G7, serotype O8:K87, F4ab+) . A total of 120 F4ab/acR phenotyped pigs were genotyped using the Porcine SNP60 BeadChip (Illumina) containing 62,163 SNPs, according to the manufacturer’s protocol. The position of the SNPs was based on the current pig genome assembly (Sscrofa10.2).
