BACKGROUND Breast cancer develops in over 7000 women each year in Ontario. These patients will all undergo some staging work-up at diagnosis. The Breast Cancer Disease Site Group of the Cancer Care Ontario Practice Guidelines Initiative reviewed the evidence and indications for routine bone scanning, liver ultrasonography and chest radiography in(More)
The development of many organs, including the lung, depends upon a process known as branching morphogenesis, in which a simple epithelial bud gives rise to a complex tree-like system of tubes specialized for the transport of gas or fluids. Previous studies on lung development have highlighted a role for fibroblast growth factors (FGFs), made by the(More)
Interferon-β (IFN-β) is widely used to treat multiple sclerosis (MS), and its efficacy was demonstrated in the setting of experimental autoimmune encephalomyelitis (EAE), an animal model of MS; however, IFN-β is not effective in treating all cases of MS. Here, we demonstrate that signaling by IFNAR (the shared receptor for IFN-α and IFN-β) on macrophages(More)
A family history of disease is a strong risk factor for testicular germ cell tumour (TGCT). In order to identify the location of putative TGCT susceptibility gene(s) we conducted a linkage search in 237 pedigrees with two or more cases of TGCT. One hundred and seventy-nine pedigrees were evaluated genome-wide with an average inter-marker distance of 10 cM.(More)
We found that absence of osteopontin (OPN) in immunocompromised Rag2(-/-) mice, which lack T and B cells, made the mice extremely susceptible to an opportunistic fungus Pneumocystis, although immunocompetent OPN-deficient mice could clear Pneumocystis as well as wild-type mice. OPN has been studied as an extracellular protein, and the role of an(More)
β-Arrestins 1 and 2 are multifunctional adaptor proteins originally discovered for their role in desensitizing seven-transmembrane receptor signaling via the heterotrimeric guanine nucleotide-binding proteins. Recently identified roles of β-arrestins include regulation of cancer cell chemotaxis and proliferation. Herein, we report that β-arrestin1(More)
OBJECTIVE Metastatic seminoma is a highly curable disease. Standard treatment comprises of combination chemotherapy. The short- and long-term toxicities of this treatment are increasingly recognised and the possibility of over treatment in such a curable disease should be considered. We have therefore assessed the use of single agent carboplatin at a dose(More)
BACKGROUND AND OBJECTIVES Cisplatin-based chemotherapy is standard care for metastatic transitional cell carcinoma (TCC) of the urinary tract. However it is not appropriate for all patients, particularly those with poor renal function. There is no clear consensus on the optimal regimen for these individuals or for those after cisplatin failure. Here we(More)
