Androgen withdrawal is the most effective form of systemic therapy for men with advanced prostate cancer. Unfortunately, androgen-independent progression is inevitable, and the development of hormone-refractory disease and death occurs within 2 to 3 years in most men. The understanding of molecular mechanisms promoting the growth of androgen-independent(More)
Well-characterized, high-quality fresh-frozen prostate tissue is required for prostate cancer research. As part of the PROCURE Prostate Cancer Biobank launched in 2007, four University Hospitals in Quebec joined to bank fresh frozen prostate tissues from radical prostatectomies (RP). As the biobank progressed towards allocation, the nature and quality of(More)
In cloning tyrosine kinase genes in dog prostate cells, a fragment of the vascular endothelial growth factor (VEGF) receptor 1 or Flt-1 was sequenced. To test for a functional protein, Flt-1 antibodies were used to probe immunoprecipitated tyrosine phosphorylated proteins. Western blotting revealed a major 170-180 kDa band and a few bands below 116 kDa in(More)
Transforming growth factor-beta (TGF-beta) plays an important role in angiogenesis and vascular function. Endoglin, a transmembrane TGF-beta binding protein, is highly expressed on vascular endothelial cells and is the target gene for the hereditary haemorrhagic telangiectasia type I (HHT1), a dominantly inherited vascular disorder. The specific function of(More)
Castrate-resistant prostate cancer (CRPC) is invariably lethal and still poorly understood. IL-6/pSTAT3 appears critical as elevated IL-6 and pSTAT3 correlate with CRPC and poor prognosis. We previously reported on the Fer tyrosine kinase being an integral component of the IL-6 pathway in PC by controlling STAT3. Since IL-6 also controls androgen receptor(More)
PURPOSE Vascular targeted photodynamic therapy with WST09 shows promise for recurrent prostate cancer after radiation but hydrophobicity in aqueous solutions limited application. We tested the safety and efficacy of WST11, a novel water soluble vascular occluding agent, for vascular targeted photodynamic therapy of the dog prostate and compared it to WST09(More)
Background:Prostate cancer shows considerable heterogeneity in disease progression and we propose that markers expressed in tumour stroma may be reliable predictors of aggressive tumour subtypes.Methods:We have used Kaplan–Meier, univariate and multivariate analysis to correlate the expression of Asporin (ASPN) mRNA and protein with prostate cancer(More)
PURPOSE Vascular targeted photodynamic therapy with WST11 (TOOKAD® Soluble) is in phase III clinical trials of an interstitial transperineal approach for focal therapy of prostate cancer. We investigated the safety and efficacy of the endourethral route in the context of benign prostatic hyperplasia in the dog model. MATERIALS AND METHODS An optical laser(More)
BACKGROUND Rodent models are often suboptimal for translational research on human prostate cancer (PCa). To better fill the gap with human, we refined the previously described orthotopic dog prostate cancer (DPC)-1 model. METHODS Cyclosporine (Cy) A was used for immune suppression at varying doses and time-periods prior and after orthotopic DPC-1 cell(More)
Pyruvate kinase (PK) exists as at least two electrophoretically distinguishable, tissue specific form in the river sturgeonAcipenser fulvenscens. In contrast with the PK isozyme system in other vertebrates, the isozyme present in muscle is also present in non-musclce tissues, notably the spleen. The presence of a five membered set of hybrids in liver,(More)
