BACKGROUND The aim of this study was to determine the effect of the phytotherapeutic agent, Permixon, on a novel coculture model of benign prostatic hyperplasia (BPH) in an effort to better understand the mode of action of the drug in vivo. METHODS The effect of Permixon, at the calculated therapeutic concentration, on the activity of 5alpha-reductase(More)
Oestrogen action is mediated via specific receptors that act as ligand-activated transcription factors. A monoclonal antibody specific to the C-terminus of human oestrogen receptor beta has been characterized and the prevalence of expression of oestrogen receptor beta protein investigated in a well defined set of breast cancers.

PURPOSE Considerable evidence has accumulated demonstrating that the 5alpha-reduction of testosterone to dihydrotestosterone occurs more efficiently in the normal and benign hyperplastic prostate than in prostate cancer tissues. Efforts have also been channeled into investigating the distribution of 5alpha-reductase isoenzymes in primary prostate tissues(More)
Paracrine interactions between primary cultured prostate epithelial cells and stromal fibroblasts were investigated in relation to morphology, growth, androgen sensitivity and secretory activities using co-cultures in which the two populations were separated by a microporous membrane. In this new model system, both cell types maintained several aspects of(More)
We have developed a coculture system for primary fibroblast and epithelial cells derived from benign prostatic hyperplasia (BPH) that retained many of the characteristics of the intact human prostate. In contrast to separately cultured prostate fibroblast and epithelial cells, cocultures of fibroblasts and epithelial cells maintained messenger ribonucleic(More)
OBJECTIVE To detect the expression and transcription pattern of MUC1 in benign and malignant disease, and in two widely studied cell lines, and to investigate the glycosylation of MUC-1 in bone metastasis of prostate cancer, as mucins have been implicated in the progression and behaviour of several cancers. MATERIALS AND METHODS RNA extracted from cell(More)
PURPOSE To investigate the effects of the phytotherapeutic agent, Permixon(R), on primary cultures of fibroblast and epithelial cells from the prostate, epididymis, testes, kidney, skin and breast and to determine the selectivity and specificity of the action of the drug. MATERIALS AND METHODS All primary cultures were examined by electron microscopy(More)
The expression and localisation of mRNAs for 5 alpha reductase Type I (5 alpha R-I) and Type II (5 alpha R-II) isoenzymes in human benign prostatic hyperplasia (BPH) were investigated by RT-PCR and by in mini hybridisation (ISH) using digoxigenin labelled riboprobes. In addition, we also examined the isoenzymes mRNA expression in primary BPH cultures of(More)
Pasteurella multocida serogroup A is commonly isolated from nasal swabs of clinically healthy calves and also from diseased lung tissue in bovine pneumonia. Here, we report the draft genome sequence of the virulent strain P. multocida 671/90, which has been characterized previously in experimental infections of calves and mice.
The role of DHT in the development of BPH has resulted in the formulation of several drugs, which have been designed to inhibit the formation of DHT by the 5alpha-reductase enzymes (5alpha-reductase type I (5alpha-RI) & 5alpha-reductase type II (5alpha-RII)). Although the function of these enzymes is well understood, the biochemical stimulus for initiation(More)
