Integrated mapping of the dog epigenome (ChIP-seq)

ABSTRACT: Dogs have become a valuable model in exploring multifaceted diseases and biology relevant to human health. Despite large-scale dog genome projects producing high-quality draft references, a comprehensive annotation of functional elements is still lacking. We addressed this through integrative next-generation sequencing of transcriptomes paired with five histone marks and DNA methylome profiling across 11 tissue types, deciphering the dog’s epigenetic code by defining distinct chromatin states, super-enhancer and methylome landscapes, and thus showed that these regions are associated with a wide range of biological functions and cell/tissue identity. In addition, we confirmed that the phenotype-associated variants are enriched in tissue-specific regulatory regions and, therefore, the tissue of origin of the variants can be traced. Ultimately, we delineated conserved and dynamic epigenomic changes at the tissue- and species-specific resolutions. Our study provides an epigenomic blueprint of the dog that can be used for comparative biology and medical research.

Affymetrix SNP array data for dog OCD samples

Project description:Obsessive-compulsive disorder (OCD), a severe mental disease manifested in time-consuming repetition of behaviors, affects 1-3% of the human population. While highly heritable, complex genetics has hampered attempts to elucidate OCD etiology. Dogs suffer from naturally occurring compulsive disorders that closely model human OCD, manifested as an excessive repetition of normal canine behaviors that only partially responds to drug therapy. The limited diversity within dog breeds makes identifying underlying genetic factors easier. We use genome wide association of 87 Doberman Pinscher cases and 63 controls to identify genomic loci associated with OCD and sequence these regions in 8 affected dogs from high-risk breeds and 8 breed-matched controls. We find 119 variants in evolutionarily conserved sites that are specific to dogs with OCD. These case-only variants are significantly more common in high OCD risk breeds compared to breeds with no known psychiatric problems. Four genes, all with synaptic function, have the most case-only variation: neuronal cadherin (CDH2), catenin alpha2 (CTNNA2), ataxin-1 (ATXN1), and plasma glutamate carboxypeptidase (PGCP). Two different case-only variants targeted the same approximately 500-bp highly conserved regulatory element between the cadherin genes CDH2 and DSC3. We functionally test these variants in a human neuroblastoma cell line and show that they cause significant changes in gene expression, likely due to disrupted transcription factor binding. This work demonstrates how we can use the unique genetics of dog breeds, and mechanistic similarities between human and dog diseases, to find genes and regulatory pathways underlying complex psychiatric disorders.

Genome-wide array comparative genomic hybridization (aCGH) profiling of copy number variations (CNVs) in various dog breeds in comparison to a reference sample

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. 53 samples of genomic DNA were hybridized to a reference sample. The dataset comprises 2 samples from each of 15 dog breeds, 10 samples from each of 2 dog breeds and 3 samples from gray wolf.

Deep sequencing of endogenous mRNA from Caenorhabditis elegans in the presence of 2-deoxy-D-glucose (DOG) at 4 different time points

Project description:Background: C. elegans fed with a chemical inhibitor of glucose, namely 2-deoxy-D-glucose (DOG), exhibit considerably extended life span. DOG, in contradiction to D-glucose, cannot be metabolized in the glycolytic pathway. This results in the fact that less glucose is available for ATP production, and thus makes DOG-feeding of the roundworms equivalent to glucose restriction. The RNA-seq data comprises 4 age groups (1, 5, 10 and 20 days after L4) Jena Centre for Systems Biology of Ageing - JenAge (www.jenage.de)

Gene expression from beagle dog mandible

Project description:In this study, beta-TCP was implanted in dog mandibles, after which the gene expression profiles and signaling pathways were monitored using microarray and Ingenuity Pathways Analysis (IPA). Following the extraction of premolars and subsequent bone healing, betaâTCP was implanted into the artificial osseous defect. Total RNA was isolated from bone tissues and gene expression profiles were examined using microarray analysis. We used microarrays to detail the global programme of gene expression and identified distinct classes of up- and down- regulated genes during this process. Waiting 3 months healing after tooth extraction from beagle dog mandibles, we drilled the holes in the dog mandibles, and implanted without and with beta-TCP. And these dog mandibles were selected for RNA extraction and hybridization on Affymetrix microarrays. After implanting beta-TCP in the dog mandibles 4, 7, 14 days, we selected sample at 3 time points: Control_4d, beta-TCP_4d, Control_7d, beta-TCP_7d, Control_14d, beta-TCP_14d.
