This study aimed to determine in the canine corpus luteum throughout the diestrus: 1) the influence of insulin on glucose utilization; 2) the regulation of genes potentially involved; and 3) the influence of hypoxia on glucose transporter expression and steroidogenesis, after treatment with cobalt chloride (CoCl2). Glucose uptake by luteal cells increased 2.7 folds (P<0.05) in response to insulin; a phenomenon related to increased expression of glucose transporter (GLUT) 4 and phosphorylation of protein kinase B (AKT)...

Heme oxygenase-1 (HO-1) is a stress-responsive enzyme that modulate immune response and oxidative stress associated with spinal cord injury (SCI). This study aimed to investigate neuronal regeneration by transplantation of mesenchymal stromal cells (MSCs) overexpressing HO-1. Canine MSCs overexpressing HO-1 were generated using a lentivirus packaging protocol. Eight beagle dogs with experimentally-induced SCI were GFP-labeled MSCs (MSC-GFP) and HO-1 overexpressed MSCs (MSC-HO-1) groups. MSCs (1 × 107 cells) were transplanted at 1 week after SCI...

Determining inflammation and itch pathway activation in patients with atopic dermatitis (AD) is fraught with the inability to precisely assess the age of skin lesions, thus affecting the analysis of time-dependent mediators. To characterize inflammatory events occurring during early experimental acute AD lesions, biopsy samples were collected 6, 24, and 48 hours after epicutaneous application of Dermatophagoides farinae house dust mites to sensitized atopic dogs. The skin transcriptome was assessed using a dog-specific microarray and quantitative PCR...

Obesity is an emerging health problem in purebred dogs. Due to their crucial role in energy homeostasis control, genes encoding adipokines are considered candidate genes, and their variants may be associated with predisposition to obesity. Searching for polymorphism was carried out in three adipokine genes (TNF, RETN and IL6). The study was performed on 260 dogs, including lean (n = 109), overweight (n = 88) and obese (n = 63) dogs. The largest cohort was represented by Labrador Retrievers (n = 136)...

Epithelial to mesenchymal transition (EMT) and the cardiovascular equivalent, endothelial to mesenchymal transition (EndoMT), contribute to a range of chronic degenerative diseases and cancer metastasis. Chronic valvulopathies exhibit some features of EndoMT and activation of developmental signalling pathways, such as osteogenesis and chondrogenesis, expression of cell differentiation markers, basement membrane damage and endothelial transformation. The aim of the present study was to investigate the potential role of developmental mechanisms in canine myxomatous mitral valve disease (MMVD) using a combination of transcriptomic array technology, RT-PCR and immunohistochemistry...

BACKGROUND: Accumulated to-date gene microarray data on Acute Respiratory Distress Syndrome (ARDS) in the Gene Expression Omnibus (GEO) represent a rich source for identifying new unsuspected targets and mechanisms of ARDS. The recently developed expression-based genome-wide association study (eGWAS) for analysis of GEO data was successfully used for analysis of gene expression of comparatively noncomplex adipose tissue, 75 % of which is represented by adipocytes. Although lung tissue is more heterogenic and does not possess a prevalent cell type for driving gene expression patterns, we hypothesized that eGWAS of ARDS samples will generate biologically meaningful results...

Cystic endometrial hyperplasia (CEH), mucometra, and pyometra are common uterine diseases in intact dogs, with pyometra being a life threatening disease. This study aimed to determine the gene expression profile of these lesions and potential biomarkers for closed-cervix pyometra, the most severe condition. Total RNA was extracted from 69 fresh endometrium samples collected from 21 healthy female dogs during diestrus, 16 CEH, 15 mucometra and 17 pyometra (eight open and nine closed-cervixes). Global gene expression was detected using the Affymetrix Canine Gene 1...

Pyometra, which is accompanied by bacterial contamination of the uterus, is defined as a complex disease associated with the activation of several systems, including the immune system. The objective of the study was to evaluate the gene expression profile in dogs with pyometra compared with those that were clinically normal. The study included uteri from 43 mongrel bitches (23 with pyometra, 20 clinically healthy). RNA used for the microarray study was pooled to four separated vials for control and pyometra...

Mesenchymal stem cells (MSCs) are somatic, multipotent stromal cells with potent immunomodulatory and regenerative properties. Although MSCs have pattern recognition receptors and are modulated by Toll-like receptor ligands, MSC-microbial interactions are poorly defined. The objectives of this study were to determine the effect of bacterial association on MSC function. We hypothesized that gastrointestinal bacteria associate with MSCs and alter their immunomodulatory properties. The effect of MSC-microbial interactions on MSC morphology, viability, proliferation, migration, and immunomodulatory functions was investigated...

Autoinflammatory disease (AID) manifests from the dysregulation of the innate immune system and is characterised by systemic and persistent inflammation. Clinical heterogeneity leads to patients presenting with one or a spectrum of phenotypic signs, leading to difficult diagnoses in the absence of a clear genetic cause. We used separate genome-wide SNP analyses to investigate five signs of AID (recurrent fever, arthritis, breed specific secondary dermatitis, otitis and systemic reactive amyloidosis) in a canine comparative model, the pure bred Chinese Shar-Pei...

In this study, we found an effective and novel therapeutic approach to atopic dermatitis (AD) therapy via treatment with a canine adipose tissue stem cell (cATSC) extract. We determined that the therapeutic application of cATSC-derived interleukin 10 (IL10) and transforming growth factor β1 (TGFβ1) effectively modulated the overloaded immune response after the induction of AD. In addition, we investigated the molecular role of the cATSC extract during AD treatment. Dogs with naturally occurring AD that was treated at Seoul National University Veterinary Teaching Hospital was enrolled in this study...

Canine atopic dermatitis (AD) is clinically similar to human AD, implicating it as a useful model of human eosinophilic allergic disease. To identify cutaneous gene transcription changes in relatively early inflammation of canine AD, microarrays were used to monitor transcription in normal skin (n=13) and in acute lesional AD (ALAD) and nearby visibly nonlesional AD (NLAD) skin (n=13) from dogs. Scanning the putative abnormally transcribed genes, several potentially relevant genes, some abnormally transcribed in both NLAD and ALAD (e...

The skin afferent lymph dendritic cell (DC) spontaneously forms clusters with autologous T cells. The role of adhesion molecules and cytokines in this process was investigated. Analysis of the expression of adhesion receptors on the canine peripheral lymph DC revealed the presence of CD54, CD58, CD18 as well as CD49d and CD49e molecules and cell surface fibronectin. The CD54 and CD58 molecules were found to play a key role in the 'spontaneous' lymph cell clustering. Antibody against fibronectin, a substrate for CD49d and CD49e receptors, reduced DC-lymphocyte binding...

The inter-species cross-reactivity of cytokine bioassays for interleukin-2 (IL2) and interleukin-6 (IL6) was investigated in the canine species. The kinetics of normal canine peripheral blood mononuclear cells (PBMC) stimulated with pokeweed mitogen (PWM), were analyzed in terms of cytokine release and responsiveness to cytokine stimulation, in conjunction with determination of cell proliferation, de novo antibody synthesis and cell surface phenotype. PBMC were stimulated with PWM at the beginning of the culture and human recombinant IL2 (rIL2) was added 3-4 days post stimulation (d...
