In determining relative gene expression by quantitative measurements of mRNA levels using real-time quantitative PCR, internal standards such as reference genes are essential. Large-scale studies evaluating (candidate) reference genes for veterinary research have not been conducted as thoroughly as for human research, although they are equally important.(More)
Domesticated animal species such as dogs and cats, with their many different characteristics and breed-specific diseases, and their close relationship and shared environment with humans, are a potentially rich source for the identification of the genetic contribution to human biology and disease. Copper toxicosis in Bedlington terriers is a genetic disease(More)
Corticosteroids interact with receptors in the central nervous system. These receptors display heterogeneity and can be distinguished as corticosterone- and aldosterone-binding mineralocorticoid receptors and dexamethasone-binding glucocorticoid receptors. Ligand specificity of mineralocorticoid receptors for either corticosterone or aldosterone seems to be(More)
Aging is associated with a progressive dysfunctioning of the hypothalamic-pituitary-adrenocortical (HPA) axis. We have studied the response of the HPA axis to stress and a hormonal (ovine corticotropin releasing factor (o-CRF) challenge in young (1.5-2 years) and aged (greater than 11 years) dogs. Compared to the young dogs, the aged animals displayed an(More)
Inherited diseases commonly emerge within pedigree dog populations, often due to use of repeatedly bred carrier sire(s) within a small gene pool. Accurate family records are usually available making linkage analysis possible. However, there are many factors that are intrinsically difficult about collecting DNA and collating pedigree information from a large(More)
Background: The role of copper accumulation in the onset of hepatitis is still unclear. Therefore, we investigated a spontaneous disease model of primary copper-toxicosis in Doberman pinschers so to gain insights into the pathophysiology of copper toxicosis, namely on genes involved in copper metabolism and reactive oxygen species (ROS) defences.
BACKGROUND Apoptosis resistance occurs in various tumors. The anti-apoptotic XIAP protein is responsible for inhibiting apoptosis by reducing caspase-3 activation. Our aim is to evaluate whether RNA inhibition against XIAP increases the sensitivity of canine cell-lines for chemotherapeutics such as TRAIL and doxorubicin. We used small interfering RNA's(More)
Congenital disorders of the hepatic portal vasculature are rare in man but occur frequently in certain dog breeds. In dogs, there are two main subtypes: intrahepatic portosystemic shunts, which are considered to stem from defective closure of the embryonic ductus venosus, and extrahepatic shunts, which connect the splanchnic vascular system with the vena(More)
BACKGROUND Hepatic fibrosis is a common outcome of hepatic injury in both man and dog. Activated fibroblasts which develop myofibroblastic characteristics play an essential role in hepatic fibrogenesis, and are comprised of three subpopulations: 1) portal or septal myofibroblasts, 2) interface myofibroblasts and 3) the perisinusoidally located hepatic(More)
BACKGROUND The availability of non-rodent animal models for human cirrhosis is limited. We investigated whether privately-owned dogs (Canis familiaris) are potential model animals for liver disease focusing on regenerative pathways. Several forms of canine hepatitis were examined: Acute Hepatitis (AH), Chronic Hepatitis (CH), Lobular Dissecting Hepatitis(More)
