Project description:This study used the NimbleGen dog whole genome CGH 2.1M tiling array to assay copy number variants in the dog genome in multiple breeds and wolf.
Project description:DNA methylation patterns reflect the status of individual tissues, such as cell composition, age, and the local environment in mammals. This experiment addressed the DNA methylation landscape in the dog genome across three breeds: Shiba, Dachshund (Miniature), and Poodle (Toy). A comprehensive profile of whole-genome DNA methylation from the whole blood of three dog breeds was generated using whole-genome bisulfite sequencing.
Project description:In a prior report, we observed two distinct lung microbiomes in healthy subjects that we termed â??pneumotypesâ??: pneumotypeSPT, characterized by high bacterial load and supraglottic predominant taxa (SPT) such as the anaerobes Prevotella and Veillonella; and pneumotypeBPT, with low bacterial burden and background predominant taxa (BPT) found in the saline lavage and bronchoscope. Here, we determined the prevalence of these two contrasting lung microbiome types, in a multi-center study of healthy subjects. We confirmed that a lower airway microbiome enriched with upper airway microbes (pneumotypeSPT) was present in ~45% of healthy individuals. Cross-sectional Multicenter cohort. BAL of 49 healthy subjects from three cohort had their lower airway microbiome assessed by 16S rDNA sequencing and microbial gene content (metagenome) was computationally inferred from taxonomic assignments. The amplicons from total 100 samples are barcoded; the barcode and other clinical characteristics (e.g. inflammatory biomarkers and metabolome data) for each sample are provided in the 'Pneumotype.sep.Map.A1.txt' file.
Project description:To study the tissue-specific evolution of regulatory elements in the mammalian lineage, we created a comprehensive map of promoters and enhancers in 4 tissues of 10 mammalian species. To map in-vivo promoters and enhancers, we performed ChIP-seq experiments for H3K4me3, H3K27ac and H3K4me1 in adult liver, muscle, brain and testis of all 10 species. The species included in the study are: macaque, marmoset, mouse, rat, rabbit, pig, dog, cat, horse and opossum. To correlate regulatory evolution to expression, we also performed RNA-seq experiments in all tissues and species submitted separately to ArrayExpress.
Project description:The Italian island of Sardinia is well known in studies of human population isolates. It is also home to the Fonni's Dog, a breed of canine whose development was reliant on the functionality of the dog. Using genome-wide variant and sequence analyses, we have characterized the Fonni's Dog relative to 27 other dog breeds from the Mediterranean region. We determine introgression events relevant to Mediterranean breed development and describe how the Fonni's dog presents an intriguing model demonstrating the characteristics of traditional human population isolates and, in particular, exhibiting the unique demographic composition of the people of Sardinia.

Project description:Whole genome sequencing of CTVT, breed dogs, and wild canids reveals pathways that are important in cancer cell survival. Comparison of these mutations with breed dogs shows that the original tumor came from a dog very similar to one of the modern Arctic breeds.
