In recent studies to clone and characterize genes coding for the corticotropin-releasing factor-binding protein (CRF-BP), analysis of the tissue distribution of the CRF-BP gene indicated a high level of expression in the rat brain. We have now characterized by immunohistochemical and hybridization histochemical means the cellular localization of CRF-BP(More)
Corticotropin-releasing factor (CRF), is a potent stimulator of synthesis and secretion of preopiomelanocortin-derived peptides. Although CRF concentrations in the human peripheral circulation are normally low, they increase throughout pregnancy and fall rapidly after parturition. Maternal plasma CRF probably originates from the placenta, which responds to(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)
Initially the hypothalamic factor responsible for the release of corticotropin (CRF), was thought to be a simple peptide. More recent work has led to the conclusion that CRF is a multifactorial complex. In 1979 we proposed that vasopressin, much disputed as a CRF candidate, was a major constituent of the complex, interacting with a potentiating the CRF(More)
Studies in mammalian skin have shown expression of the genes for corticotropin-releasing hormone (CRH) and the related urocortin peptide, with subsequent production of the respective peptides. Recent molecular and biochemical analyses have further revealed the presence of CRH receptors (CRH-Rs). These CRH-Rs are functional, responding to CRH and urocortin(More)
Regulation of the rapid compensatory growth seen in the remaining adrenal gland of rats following unilateral adrenalectomy is poorly understood. The role of adrenocorticotropic hormone (ACTH) is obscure as immunoneutralization of circulating ACTH does not affect the observed compensatory growth or hyperplasia. This finding, together with the fact that(More)
OBJECTIVE To determine whether circulating markers of oxidative stress are elevated in pre-eclampsia when appropriate precautions are taken to prevent in vitro oxidation DESIGN A prospective study. SETTING Nuffield Department of Obstetrics and Gynaecology, Oxford and The William Harvey Institute, London. SAMPLE Three groups of women: those with(More)
Ovine corticotropin-releasing hormone (CRF)-like immunoreactivity has been examined in the rat hypothalamus by light microscopy. Immunoreactivity was found in nerve fibers of the median eminence, mainly in the external zone around the portal vessels. In rats pretreated with colchicine or with hypothalamic knife cuts, small to moderate sized cells with two(More)
We report the purification of human corticotrophin-releasing factor-binding protein (hCRF-BP) using repeated affinity chromatography (with the aid of synthetic CRF immobilized on Sepharose 4B solid phase) followed by gel filtration. Presence of the binding protein was tracked throughout the procedure by its ability to inhibit binding of 125I-labelled hCRF(More)
ED(27) trophoblast-like cells were prepared from human chorionic villus samples obtained at 9 weeks gestation and have been grown continuously in vitro without phenotypic drift for nearly a decade. These cells express many trophoblast markers, including cytokeratin, placental alkaline phosphatase (PLAP), secretion of 17beta-estradiol, and a microvillous(More)
