Project description:The study was undertaken to analyze the effect of canine uterine bacterial infection (Pyometra) on local gene expression patterns in the uteri. The results show profound upregulation of various expected genes related to both the innate and innate immune system. In addition, there was a marked upregulation of many genes associated with proteolysis. Moreover, the bacterial disease resulted in downregulation of a large number of homeobox and zinc finger transcription factors. Keywords: Expression profiling by array Gene expression patterns in the uterus from dogs with pyometra disease compared to healthy dogs. 4 replicates each.

Project description:Introduction: The relationship between epilepsy and cognitive dysfunction has been investigated in canines, and memory impairment was prevalent in dogs with epilepsy. There is some evidence that canines with epilepsy have greater amyloid-β (Aβ) accumulation and neuronal degeneration than healthy controls. The present study investigated plasma Aβ42 levels and performed proteomic profiling in dogs with refractory epilepsy and healthy dogs. Methods: In total, eight dogs, including four healthy dogs and four dogs with epilepsy, were included in the study. Blood samples were collected to analyze Aβ42 levels and perform proteomic profiling. Changes in the plasma proteomic profiles of dogs were determined by nano LC-MS/MS. Results and discussion: The plasma Aβ42 level was significantly higher in dogs with epilepsy (99 pg/mL) than in healthy dogs (5.9 pg/mL). In total, 155 proteins were identified, and of these, the expression of 40 proteins was altered in epilepsy. Among these proteins, which are linked to neurodegenerative diseases, 10 (25%) were downregulated in dogs with epilepsy, whereas 12 (30%) were upregulated. The expression of the acute phase proteins haptoglobin and α2-macroglobulin significantly differed between the groups. Complement factor H and ceruloplasmin were only detected in epilepsy dogs, suggesting that neuroinflammation plays a role in epileptic seizures. Gelsolin, which is involved in cellular processes and cytoskeletal organization, was only detected in healthy dogs. Gene Ontology annotation revealed that epilepsy can potentially interfere with biological processes, including cellular processes, localization, and responses to stimuli. Seizures compromised key molecular functions, including catalytic activity, molecular function regulation, and binding. Defense/immunity proteins were most significantly modified during the development of epilepsy. In Kyoto Encyclopedia of Genes and Genomes pathway analysis, complement and coagulation cascades were the most relevant signaling pathways affected by seizures. The findings suggested that haptoglobin, ceruloplasmin, α2-macroglobulin, complement factor H, and gelsolin play roles in canine epilepsy and Aβ levels based on proteomic profiling. These proteins could represent diagnostic biomarkers that, after clinical validation, could be used in veterinary practice as well as proteins relevant to disease response pathways. To determine the precise mechanisms underlying these relationships and their implications in canine epilepsy, additional research is required.

Project description:Dogs frequently develop glaucoma, a disease that leads to vision loss due to loss of retinal ganglion cells and degeneration of axons within the optic nerve. We used Affymetrix Gene chips to characterize transcriptional changes between healthy and glaucomatous retinas. These data describe gene expression changes in the canine retina with glaucoma. RNA was isolated from the retinas of 5 dogs with advanced glaucoma and from 5 normal individuals.

Project description:Pet dogs may provide a useful large-animal model of spontaneously occuring non-Hodgkin lymphoma, but complete molecular characterization is lacking. We used gene expression microarrays to molecularly characterize canine lymphoma, and found similarities between canine B-cell lymphoma and human diffuse large B-cell lymphoma. We isolated RNA from pre-treatment biopsies from dogs with B-cell lymphoma and performed gene expression profiling.

Project description:Ameloblastomas are odontogenic tumors that are rare in people but have a relatively high prevalence in dogs. Because canine acanthomatous ameloblastomas (CAA) have clinicopathologic and molecular features in common with human ameloblastomas (AM), spontaneous CAA can serve as a useful translational model of disease. However, the molecular basis of CAA and how it compares to AM are incompletely understood. In this study, we compared the global genomic expression profile of CAA with AM and evaluated their dental origin by using a bulk RNA-seq approach. For these studies, healthy gingiva (HGIN) and canine oral squamous cell carcinoma (COSCC) served as controls. We found that aberrant RAS signaling, and activation of the epithelial-to-mesenchymal transition cellular program are involved in the pathogenesis of CAA, and that CAA is enriched with genes known to be upregulated in AM including those expressed during the early stages of tooth development, suggesting a high level of molecular homology. These results support the model that domestic dogs with spontaneous CAA have potential for pre-clinical assessment of targeted therapeutic modalities against AM.
