Osteosarcoma is the most common primary bone tumour of both children and dogs. It is an aggressive tumour in both species with a rapid clinical course leading ultimately to metastasis. In dogs and children distant metastasis occurs in >80% of individuals treated by surgery alone. Both canine and human osteosarcoma has been shown to contain a sub-population(More)
The epithelial-mesenchymal transition (EMT) is a crucial event that occurs during cancer metastasis and can be induced by transforming growth factor-β (TGF-β) in various tumor cells in vitro. However, little is known about the effects of TGF-β in canine mammary gland tumors (CMGTs). Here, we investigated the role of TGF-β in CMGT. We observed that treatment(More)
BACKGROUND The NSAID mavacoxib (Trocoxcil™) is a recently described selective COX-2 inhibitor used for the management of inflammatory disease in dogs. It has a long plasma half-life, requiring less frequent dosing and supporting increased owner compliance in treating their dogs. Although the use of NSAIDs has been described in cancer treatment in dogs,(More)
We produced 23 cloned cell lines from parental CHMp, which was previously established from a canine mammary adenocarcinoma patient in our laboratory. Two representative cloned cell lines, namely, CHMp-5b and -13a, were selected and characterized for cellular morphology, growth potential and expression of some tumour-related proteins. Subsequently, we(More)

Expression of the carbohydrate antigens sialyl Lewis x (sLe(x)) and a (sLe(a)) was evaluated in feline mammary gland tumours (FMGT). Immunohistochemical analysis of tissues from 21 FMGT patients and 11 healthy cats revealed significantly higher sLe(x) and sLe(a) antigen expression in adenocarcinoma tissues compared with that of normal mammary tissues (P(More)
PURPOSE In humans, primary open-angle glaucoma (POAG) is a complex genetic disorder and is the leading cause of visual impairment. Although all relevant genes were not identified, a small subset of the condition is found to be caused by mutations in the MYOC and CYP1B1 genes. Inherited glaucoma also occurs in several breeds of dogs including beagles.(More)
To determine the influence of the transplantation site of canine osteosarcoma (OS) cell lines on tumour growth and pulmonary metastasis, three OS cell lines were transplanted into nude mice via subcutaneous (SC), intratibial (IT) or intravenous (IV) injection. IT-xenografts exhibited greater potential for developing primary masses and pulmonary metastasis(More)
