Glucocorticoids play an essential role in maintaining basal and stress-related homeostasis, and lack of glucocorticoid action is incompatible with life in primates. Most known effects of glucocorticoids are mediated by the intracellular GR. The magnitude of a cell's response to glucocorticoids depends both on the hormone level it is exposed to and on its(More)
CONTEXT The human placenta is a complex tissue and possesses, through its capacity to proliferate and to invade maternal tissue, qualities that are usually found in malignant tumors. Osteopontin (OPN) and CEACAM1 may regulate these processes. OBJECTIVE The present study was designed to investigate the expression pattern of OPN in the human placental(More)
The circadian rhythm of salivary cortisol was studied in 10 healthy women every 4 weeks throughout pregnancy. In addition, in 12 women the diurnal patterns of salivary cortisol, serum cortisol, plasma ACTH, plasma CRH and serum progesterone were analysed in late third trimester pregnancy and again 3-5 days after delivery. Salivary cortisol profiles(More)
Hypothalamic corticotropin-releasing hormone (CRH) is the principal regulator of the hypothalamus-pituitary-adrenal axis in mammals. In addition, immunoreactive CRH is also present at peripheral sites, where it is thought to act as a proinflammatory peptide. However, the source of peripheral CRH has remained obscure. Human lymphocytes were shown to produce(More)
Using corticotrophin-releasing hormone-binding protein (CRHBP) purified from human plasma and a 25 amino acid peptide corresponding to the C-terminus of CRHBP we have been able to produce rabbit polyclonal antisera specific for CRHBP. This has allowed the development of a radioimmunoassay which is able to detect CRHBP specifically in human plasma regardless(More)
DESIGN Testosterone treatment is essential for the induction and maintenance of virilization of female-to-male (FTM) transsexuals. Aim To test the safety of a novel testosterone preparation for this purpose. METHODS Parenteral long-acting testosterone undecanoate (TU) was administered to 17 FTM transsexuals over 36 months. Observations were made while(More)
The molecular mechanisms leading to increased cellular proliferation rates and, thus, tumor formation in the anterior pituitary gland are poorly understood. The cyclin-dependent kinase inhibitor p27Kip1 is a key molecule regulating the G1 phase of the cell cycle in many cell types. Furthermore, it was shown that p27 knock-out mice develop(More)
In the present study we investigated the expression of the cell cycle inhibitor p27 in endometrial neoplasia using immunohistochemistry with a p27-specific antibody. Expression of p27 in endometrial carcinomas was compared with expression in the normal endometrium throughout the cycle. Normal endometrial cells showed strong nuclear expression of p27.(More)
