Project description:In small animals, diarrhoea is a regular presentation, the aetiology of which can be varied, from an isolated self-limiting event to more serious episodes requiring symptomatic and supportive treatment. Chronic diarrhoea, defined as diarrhoea lasting longer than 3 weeks, is a relatively common problem often prompting referral for more detailed investigation. Although the potential cause of chronic diarrhoea includes chronic intestinal parasitism and alimentary neoplasia (specifically lymphoma), the majority of these dogs will be diagnosed with idiopathic canine chronic enteropathy (CCE), previously referred to as idiopathic inflammatory bowel disease (IBD). Of those cases diagnosed with CCE, further subdivision based on response to treatment trials leads to a final diagnosis of antibiotic responsive diarrhoea (ARD), food responsive diarrhoea (FRD) or idiopathic inflammatory bowl disease (IBD). The aim of this study was to compare the proteomes of faeces of dogs with chronic enteropathies and a population of healthy dogs, and furthermore to identifying proteins that might be useful in distinguishing FRD from ARD from IBD.
Project description:We used single-cell RNA sequencing to characterize the heterogeneity duodenal tissue in healthy and chronic inflammatory enteropathy (CIE) affected dogs.
Project description:We performed a comparative immunology case study of client-owned dogs to determine if immune and skin gene expression profiles in spontaneous canine chronic cutaneous lupus erythematosus (CCLE) with concomitant systemic autoimmunity mirror those observed in human CCLE.

Project description:Spontaneous canine head and neck squamous cell carcinoma (HNSCC) represents an excellent model of human HNSCC but is greatly understudied. To better understand and utilize this valuable resource, we performed a pilot study that represents its first genome-wide characterization by investigating 12 canine HNSCC cases, of which 9 are oral, via high density array comparative genomic hybridization and RNA-seq. The analyses reveal that these canine cancers recapitulate many molecular features of human HNSCC. These include analogous genomic copy number abnormality landscapes and sequence mutation patterns, recurrent alteration of known HNSCC genes and pathways (e.g., cell cycle, PI3K/AKT signaling), and comparably extensive heterogeneity. Amplification or overexpression of protein kinase genes, matrix metalloproteinase genes, and epithelial–mesenchymal transition genes TWIST1 and SNAI1 are also prominent in these canine tumors. This pilot study, along with a rapidly growing body of literature on canine cancer, reemphasizes the potential value of spontaneous canine cancers in HNSCC basic and translational research.
Project description:This study used two different NimbleGen platforms to identify canine CNVs. The first identifies genome-wide CNVs while the second genotypes all known canine CNVs in a large panel of dogs from multiple breeds.
