A key to the development of improved pharmacological treatment strategies for cancer is an understanding of the integration of biochemical pathways involved in both tumorigenesis and cancer suppression. Furthermore, genetic markers that may predict the outcome of targeted pharmacological intervention in an individual are central to patient-focused treatment(More)
Background: Effective treatment of prostate cancer should be based on targeting interactions between tumour cell signalling pathways and key converging downstream effectors. Here, we determined how the tumourigenic phosphoinositide 3-kinase/ protein kinase B (PI3K/AKT), tumour-suppressive phosphatase and tensin homologue deleted on chromosome 10 (PTEN) and(More)
Phytoestrogens are plant-derived compounds with oestrogenic activity. They are common in both human and animal diets, particularly through soy-based foods. This study assessed whether exposure of adult male rats to a high phytoestrogen diet for 3-25 days affected their fertility, and assessed possible mechanisms through which phytoestrogens may disrupt(More)
Prostate cancer (PCa) is a leading cause of cancer-related death of men globally. Since its introduction, there has been intense debate as to the effectiveness of the prostate specific antigen (PSA) test as a screening tool for PCa. It is now evident that the PSA test produces unacceptably high rates of false positive results and is not prognostic. Here we(More)
Transgelin is a shape change sensitive 22 kDa actin-binding protein of the calponin family. It contains a C-terminal calponin-like module (CLIK(23)) and an upstream positively charged amino acid region required for actin binding. Transgelin is ubiquitous to vascular and visceral smooth muscle and is an early marker of smooth muscle differentiation, where(More)
Management of patients with prostate cancer is currently based on imperfect clinical, biological, radiological and pathological evaluation. Prostate cancer aggressiveness, including metastatic potential, remains difficult to accurately estimate. In an attempt to better adapt therapeutics to an individual (personalized medicine), reliable evaluation of the(More)
Oxytocin is present in the male reproductive tract and has been shown to increase contractility in the epididymis and to modulate steroidogenesis. This study investigated the effects of oxytocin in the testis in vivo, and the presence and cellular localization of oxytocin receptors in the reproductive tract of rams. During the breeding season, mature rams(More)
Copper is vital to cell function. The influx of reduced copper ions is controlled by two functionally homologous transmembrane solute carrier transporters CTR1 (encoded by SLC31A1) and CTR2 (encoded by SLC31A2). These copper transporters vary in their expression profiles and intracellular localisation patterns. CTR1 plays roles in the developing embryo as(More)
Transgelin is an actin-binding protein shown to be tumour-suppressive. Loss of transgelin expression in transformed cells is associated with oncogenesis. This study aimed to determine whether transgelin expression was suppressed in prostate cancer. An in silico meta-analysis with public-domain expressed-sequence-tag libraries of normal human prostate(More)
