The association of abnormal spermatogenesis in men with Y chromosome deletions suggests that genes important for spermatogenesis have been removed from these individuals. Recently, genes encoding two putative RNA-binding proteins (RBM and DAZ/SPGY) have been mapped to two different regions of the human Y chromosome. Both of these genes encode proteins that(More)
In vitro the mineralocorticoid receptor is non-specific and does not distinguish between aldosterone and cortisol. In vivo certain tissues with this receptor are aldosterone selective (eg, kidney and parotid) whereas others with the same receptor are not (eg, hippocampus and heart). Experiments in rats showed that 11 beta-hydroxysteroid dehydrogenase (which(More)
Two ovarian cell lines were derived from the ascites of a patient before and after the onset of resistance to chemotherapy involving cis-platinum, chlorambucil and 5-fluorouracil. Characterization of these lines shows them to have various features in common and some significant differences. Cytologically the lines cannot be distinguished and they both(More)
PURPOSE To determine whether BCG therapy could upregulate interleukin-6 (IL-6) production in human transitional cell carcinomas (TCC). MATERIALS AND METHODS Immunohistochemistry of tumor biopsies and urinary cytospins and ELISA studies of urine from bladder cancer patients and TCC cell-line supernatants, before and after exposure to BCG, were performed.(More)
Sixty-four patients (37 stage I and 27 stage II) with low grade non-Hodgkin's lymphoma were treated by surgical excision alone (two patients) or with radiotherapy (53 patients), chemotherapy (five patients) or both (four patients). Actuarial survival was 80.7% at 5 years and 77.9% at 10 years. Actuarial recurrence-free survival at 10 years was 49.4% for(More)
In 215 patients with operable breast cancer (T1-T3, N0-1, M0) and no other or previous cancer, presenting to a single breast unit, sufficient tumour was available for the prospective determination of four putative biochemical markers of prognosis: oestrogen receptor (ER) activity, cathepsin D (cath D), epidermal growth factor receptor (EGFR) activity and(More)
This study examines the expression of the insulin-like growth factor type 1 receptor (IGF-1R) in colorectal neoplasia. Previous studies have shown that the IGF-1R is expressed at high levels in normal embryonic stem cells and in many cancer phenotypes. However, lower IGF-1R levels are expressed in some advanced cancer phenotypes. The timing of and the(More)
The enzyme 11 beta-hydroxysteroid dehydrogenase (11 beta-OHSD), which catalyses the conversion of cortisol to the inactive steroid cortisone in man (and corticosterone to 11-dehydrocorticosterone in rodents), was demonstrated by immunohistochemistry in skin biopsy samples from healthy volunteers and from patients with psoriasis and eczema. In-vitro studies(More)
Follistatin is a binding protein for the activin and inhibin family of hormones, regulating their biological activity. In the male reproductive tract, the interaction of these factors is likely to be involved in the regulation of the proliferation of several cell types. We have investigated the presence of follistatin and activin A in seminal plasma using(More)
The diagnosis of post-menopausal atrophy should preferably be confirmed before any trial of oestrogen treatment for genito-urinary symptoms. The ideal method, cytological analysis of a vaginal wall smear, is not always feasible in elderly women. Might physical examination alone be sufficient? This study aimed to determine which clinical features might best(More)
