Project description:Canine muscular dystrophy (CXMDJ) is a dog model of the lethal X-linked muscle disorder Duchenne muscular dystrophy (DMD), which is caused by loss of dystrophin. Gene expression profile was analyzed in the diaphragm muscles of normal Beagle dogs and CXMDJ before and 1 hour after initial respiration. Diaphragm were isolated from four groups (normal Beagle dogs and CXMDJ before and 1 hour after initial respiration). Total RNA was purified and prepared to Agilent-021193 Canine (V2) Gene Expression Microarray (Feature Number version) (Agilent Technologies) using Agilkent reagents and protocols. The mRNA levels of differential expressed genes from gene chip analysis were confirmed by quantitative real-time PCR assay.

Project description:Canine gastric dilatation-volvulus (GDV) is a common life-threatening condition occurring primarily in large and giant breeds with a 3.9% to 36.7% lifetime risk. GDV is a complex disease with risk factors including age, diet, behavior, family history, and genetics. The genetic correlates of GDV have not previously been systematically explored. We undertook multiplatform genome-wide association analysis (GWAS) of 253 dogs including 106 healthy dogs and 147 dogs with at least one GDV episode. The study included ten dog breeds enriched for Borzoi, German Shepherd (GSD), Great Dane, and Standard Poodle. SNP array genotyping was performed on constitutional DNA from all 241 samples to identify GDV-associated SNPs and CNVs. To increase the coverage of our study we performed imputation analysis of the SNP data as well as additional whole genome sequencing (WGS) on a subset of 33 dogs (15 healthy dogs and 18 GDV patients from the three most represented breeds). Twenty-one patients were genotyped by both SNP and WGS platforms. The GWAS was conducted across breeds as well as on specific breeds using a mixed linear model adjusting for relatedness, population structure and sex. After genome-wide Bonferroni correction, we identified a significant protective GDV-associated SNP, rs851737064, occurring in an intergenic region, across all breeds. The signal was most significant in Collies, German Shorthaired Pointers, and Great Danes. Subsequent focused analysis across these three breeds identified 12 additional independent, protective and deleterious SNPs with significant GDV association. Additional GWAS conducted on Borzoi, GSD and Great Dane yielded significant genome-wide GDV associations in 11 independent SNPs, while that in Borzoi alone identified 2 independent GDV-associated SNPs. We then used WGS data to validate the imputation analysis. Notable significant SNPs included genes involved in gastric tone and motility including VHL, NALCN, and PRKCZ. From the WGS data we also detected two independent GDV-associated SNPs in Borzoi, GSD and Great Dane breeds on an intergenic region on chromosome 7 not covered by previous analyses. These data provide important new information regarding canine GDV risk factors and facilitate generation of hypotheses regarding the genetic and molecular underpinnings this syndrome.

Project description:We previously reported the non-viral derivation of transgene-free induced pluripotent stem cells (iPSCs) from somatic fibroblasts of a female beagle dog using an optimized induction medium and non-transgene-integrating episomal vectors. Here, we report derivation of an induced pluripotent stem cell line OF35Y-iPS from a male beagle dog, which showed standard characteristics of pluripotency such as a strong gene expression profile of pluripotency markers, differentiation potential into all three germ layers, and normal karyotype (78XY). Furthermore, we demonstrated the iPSC line was suitable for genome editing technology. The novel iPSC line would be a useful foothold for stem cell research and regenerative veterinary medicine

Project description:Purpose: The transcriptome profiles were compared among groups of chronic stress exposure and control in two different breeds to identify genes and pathways related to response to chronic stress in the pituitary-adrenal axis. Methods: 6 male adult CFD and 6 Beagles were chosen at random with the similarities in good health, weight and other aspects. Separately, 3 of these two breeds were freely selected for the stress exposure via intermittent electrical stimulation and restraint stress, while the other 3 of these two breeds were non-disposed for normal control.The details for the disposal of dogs were: every morning dogs were restrained and electrical stimulations were exerted with a stable current of 10 mA for 6 s and then with a 6 s interval, lasting for 20 min every day. The duration of disposal was ten days.ll 12 dogs were killed by air embolism in the 11th day. Subsequently, pituitary and adrenal cortex tissues were fast collected and isolated for further high-sequencing. Results: 8 cDNA libraries were constructed for RNA-seq. A number of reads ranging from 53,295,978 to 65,414,932 was obtained in those 8 groups. About 10,000 genes and transcripts were annotated in each group. Besides,A total of 40, 346, 376, 69, 70, 38, 57, and 71 DEGs were detected in the contrasts of BP1_vs_BP2, CFDP1_vs_CFDP2, BP1_vs_CFDP1, BP2_vs_CFDP2, BAC1_vs_BAC2, CFDAC1_vs_CFDAC2, BAC1_vs_CFDAC1, and BAC2_vs_CFDAC2, respectively.

Project description:Gene expression from beagle dog mandible
| PRJNA132155 | ENA
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.

Project description:Dog breeding promotes within-group homogeneity through conformation to strict breed standards and also drives between-group heterogeneity in pursuit of distinct morphological forms and characteristic breed traits. In this study, the genotype-first approach was adapted to the dog genome to investigate coding variation from over 2000 dogs, leading to discoveries of new mutations related to craniofacial morphology and stature. Breed enriched variants were prioritized according to gene constraint, which was calculated using a mutation model derived from trinucleotide substitution probabilities in the dog. Most priority variants were not associated with genomic signatures for breed differentiation, as these regions were enriched for constrained genes intolerant to nonsynonymous variation, suggesting a model of breed phenotype diversification based on regulatory changes to essential genes. Identification of trait-associated variants in dogs informs new biological roles of genes. Improved collection of breed disease risk data, along with increased breed representation, will drive further discoveries.
