Abstract
Corticotropin-releasing hormone (CRH) and its receptors are expressed in human placenta. Recently, the impaired function of this system has been associated with a number of complications of pregnancy, including pre-eclampsia. The aim of the study was to test the hypothesis that CRH participates in the pathophysiology of pre-eclampsia through the induction of macrophage-mediated apoptosis of extravillous trophoblasts (EVTs). We found that the expression of CRH was increased in the EVT of the placental bed biopsy specimens from pre-eclamptic pregnancies (1.8-fold increase; P < 0.05). In addition, significantly larger numbers of apoptotic EVT were detected in pre-eclamptic placentas compared with normal ones (P < 0.05), and only in pre-eclamptic placentas, decidual macrophages were found to be Fas ligand (FasL)-positive. In vitro studies on the effect of CRH on human macrophages suggested that CRH induced the expression of the FasL protein in human macrophages and potentiated their ability to induce the apoptosis of a Fas-expressing EVT-based hybridoma cell line in co-cultures. These findings demonstrate a possible mechanism by which the aberrant expression of CRH in pre-eclampsia may activate the FasL-positive decidual macrophages, impair the physiological turnover of EVT and eventually disturb placentation.

Abstract
Corticotropin-releasing factor (CRF), also termed corticotropin-releasing hormone (CRH) or corticoliberin, is the major regulator of the adaptive response to internal or external stresses. An essential component of the adaptation mechanism is the adrenal gland. CRF regulates adrenal function indirectly through the central nervous system (CNS) via the hypothalamic-pituitary-adrenal (HPA) axis and via the autonomic nervous system by way of locus coeruleus (LC) in the brain stem. Accumulating evidence suggests that CRF and its related peptides also affect the adrenals directly, i.e. not through the CNS but from within the adrenal gland where they form paracrine regulatory loops. Indeed, CRF and its related peptides, the urocortins (UCNs: UCN1, UCN2 and UCN3), their receptors CRF type 1 (CRF(1)) and 2 (CRF(2)) as well as the endogenous pseudo-receptor CRF-binding protein (CRF-BP) are all expressed in adrenal cortical, medullary chromaffin and resident immune cells. The intra-adrenal CRF-based regulatory system is complex and depends on the balance between the local concentration of CRF ligands and the availability of their receptors.

Abstract
Human reproduction is remarkably inefficient, with more than half of spontaneous conceptions failing to complete the first trimester. However, little is known on the molecular events that take place at the implantation site during abortion. Here, we examined the hypothesis that the expression of the proapoptotic Fas/FasL system at the implantation site is impaired in abortions. We found that, in contrast to normal pregnancy, abortive deciduas contain leukocytes that are positive for FasL and extravillous trophoblasts (EVTs), which show increased expression of Fas and increased rates of apoptosis. In addition, the neuropeptides, corticotropin-releasing hormone and urocortin, were elevated in placental material obtained from abortions. In vitro, these peptides induced the expression of FasL in decidual lymphocytes (DL) obtained from elective termination of pregnancy placentas and thus potentiated the cells' ability to induce Fas-mediated apoptosis in an EVT-based hybridoma cell line. Finally, DL from abortion sites effectively induced apoptosis of EVT without prior treatment. It is possible that these events may impede successful early placentation and thus contribute to the pathophysiology of human abortion.

Abstract
Although corticotropin-releasing hormone (CRH) and Fas ligand (FasL) have been documented in ovarian carcinoma, a clear association with tumour progression and immuno-escape has not been established. FasL plays an important role in promoting tumour cells' ability to counterattack immune cells. Here, we examined immunohistochemically the expression of CRH, CRHR1, CRHR2 and FasL in 47 human ovarian cancer cases. The ovarian cancer cell lines OvCa3 and A2780 were further used to test the hypothesis that CRH might contribute to the immune privilege of ovarian tumours, by modulating FasL expression on the cancer cells. We found that CRH, CRHR1, CRHR2 and FasL were expressed in 68.1, 70.2, 63.8 and 63.8% of the cases respectively. Positivity for CRH or FasL expression was associated with higher tumour stage. Finally, CRH increased the expression of FasL in OvCa3 and A2780 cells through CRHR1 thereby potentiated their ability to induce apoptosis of activated peripheral blood lymphocytes. Corticotropin-releasing hormone produced by human ovarian cancer might favour survival and progression of the tumour by promoting its immune privilege. These findings support the hypothesis that CRHR1 antagonists could potentially be used against ovarian cancer.

Abstract
Corticotropin-releasing factor (CRF) affects catecholamine production both centrally and peripherally. The aim of the present work was to examine the presence of CRF, its related peptides, and their receptors in the medulla of human and rat adrenals and their direct effect on catecholamine synthesis and secretion. CRF, urocortin I (UCN1), urocortin II (UCN2), and CRF receptor type 1 (CRF1) and 2 (CRF2) were present in human and rat adrenal medulla as well as the PC12 pheochromocytoma cells by immunocytochemistry, immunofluorescence, and RT-PCR. Exposure of dispersed human and rat adrenal chromaffin cells to CRF1 receptor agonists induced catecholamine secretion in a dose-dependent manner, an effect peaking at 30 min, whereas CRF2 receptor agonists suppressed catecholamine secretion. The respective effects were blocked by CRF1 and CRF2 antagonists. CRF peptides affected catecholamine secretion via changes of subplasmaliminal actin filament polymerization. CRF peptides also affected catecholamine synthesis. In rat chromaffin and PC12 cells, CRF1 and CRF2 agonists induced catecholamine synthesis via tyrosine hydroxylase. However, in human chromaffin cells, activation of CRF1 receptors induced tyrosine hydroxylase, whereas activation of CRF2 suppressed it. In conclusion, it appears that a complex intraadrenal CRF-UCN/CRF-receptor system exists in both human and rat adrenals controlling catecholamine secretion and synthesis.

Abstract
OBJECTIVE To investigate whether corticotropin-releasing hormone (CRH) and corticotropin (ACTH) plasma concentrations in women diagnosed with preterm labor are of potential clinical value in the assessment of the risk of preterm birth. METHOD Plasma samples of 79 women diagnosed with preterm labor were used in this study. Samples were divided into three groups based on the week of gestation (24th-28th, 29th-32nd, 33rd-37th). CRH and ACTH values were determined by ELISA. RESULT Mean maternal peripheral plasma values of CRH and ACTH were significantly higher (p<0.001) in women who were initially diagnosed with preterm labor and finally delivered a preterm birth, compared to women with the same diagnosis but with term birth. CONCLUSION CRH and ACTH serum levels in women diagnosed with preterm labor could be used as predictors for the timing of parturition.

Abstract
CRF, CRF-related peptides and CRF receptors constitute a complex physiological system which has a key role in facilitating the adaptation of the organism to the stressful stimuli of the environment. The behavioral, endocrine, autonomic and immune branches of stress response are considered to be under the coordinating effects of CRF and its related peptides. The effects of these peptides are mediated through two distinct receptors, types 1 and 2 CRF receptors (CRF(1) and CRF(2)). The two receptors are encoded by separate genes and belong to the G-coupled receptor superfamily. The wide influence of the CRF system on physiological processes in both brain and periphery, suggests the implication of the respective peptides in the pathophysiology of numerous disorders which involve dysregulated stress responses. The potential use of CRF antagonists in such disorders is currently under intense investigation. Furthermore, such compounds have been invaluable in elucidating the physiology of the CRF system. This review will focus on existing data on the structural and pharmacological characteristics as well as the experimental and potential clinical uses of non-peptide, small molecule CRF antagonists.

Abstract
Urocortin (UCN) is a 40 amino acid peptide which is closely related to corticotropin-releasing hormone and binds with high affinity to both CRH type 1 and type 2 receptors. UCN is expressed in human reproductive tissues including endometrium, ovary, and placenta. This study was designed to investigate the cellular localization of UCN at the implantation site of the human blastocyst, as well as the regulation of the UCN promoter by two major intracellular signaling pathways, the cAMP/PKA and diacylglycerol/PKC pathways, in cells of placental origin. For this reason, immunohistochemistry was performed on tissue sections from paraffin-embedded human first trimester placentas and freshly isolated human invasive extravillous trophoblast cells (EVT) were analyzed for UCN expression using RT-PCR and immunofluorescence. Finally, UCN promoter activity was analyzed in the JEG3 human choriocarcinoma cell line. Immunohistochemistry revealed expression of UCN in the cytotrophoblast, the EVT and decidual cells. Both UCN mRNA and peptide were detectable in freshly isolated EVT. Finally, a human UCN promoter luciferase reporter construct transfected into JEG3 cells was significantly inducible by phorbol ester plus ionomycin, but not by phorbol ester alone or by forskolin. Collectively, the present study reports the expression of UCN in EVT and the activation of the UCN gene promoter by the diacylglycerol/PKC pathway. The functional significance of urocortin for the physiology of EVT requires further investigation.
