Abstract
Background The decidua has been implicated in the “terminal pathway” of human term parturition, which is characterized by the activation of pro-inflammatory pathways in gestational tissues. However, the transcriptomic changes in the decidua leading to terminal pathway activation have not been systematically explored. This study aimed to compare the decidual expression of developmental signaling and inflammation-related genes before and after spontaneous term labor in order to reveal their involvement in this process. Methods Chorioamniotic membranes were obtained from normal pregnant women who delivered at term with spontaneous labor (TIL, n = 14) or without labor (TNL, n = 15). Decidual cells were isolated from snap-frozen chorioamniotic membranes with laser microdissection. The expression of 46 genes involved in decidual development, sex steroid and prostaglandin signaling, as well as pro- and anti-inflammatory pathways, was analyzed using high-throughput quantitative real-time polymerase chain reaction (qRT-PCR). Chorioamniotic membrane sections were immunostained and then semi-quantified for five proteins, and immunoassays for three chemokines were performed on maternal plasma samples. Results The genes with the highest expression in the decidua at term gestation included insulin-like growth factor-binding protein 1 (IGFBP1), galectin-1 (LGALS1), and progestogen-associated endometrial protein (PAEP); the expression of estrogen receptor 1 (ESR1), homeobox A11 (HOXA11), interleukin 1β (IL1B), IL8, progesterone receptor membrane component 2 (PGRMC2), and prostaglandin E synthase (PTGES) was higher in TIL than in TNL cases; the expression of chemokine C-C motif ligand 2 (CCL2), CCL5, LGALS1, LGALS3, and PAEP was lower in TIL than in TNL cases; immunostaining confirmed qRT-PCR data for IL-8, CCL2, galectin-1, galectin-3, and PAEP; and no correlations between the decidual gene expression and the maternal plasma protein concentrations of CCL2, CCL5, and IL-8 were found. Conclusions Our data suggests that with the initiation of parturition, the decidual expression of anti-inflammatory mediators decreases, while the expression of pro-inflammatory mediators and steroid receptors increases. This shift may affect downstream signaling pathways that can lead to parturition.

Abstract
Acute chorioamnionitis of infectious origin and chronic chorioamnionitis of immunological origin are two major placental lesions of spontaneous preterm birth with elevated amniotic fluid interleukin-6 and CXCL10 concentrations, respectively. The changes in the amniotic fluid proteome associated with intra-amniotic infection and acute chorioamnionitis are well defined, yet alterations unique to chronic chorioamnionitis remain to be elucidated. This study was conducted to determine those amniotic fluid proteins changing specifically in the presence of chronic chorioamnionitis. Amniotic fluid obtained from acute chorioamnionitis, chronic chorioamnionitis and gestational age-matched controls were analysed by two-dimensional (2D) difference in gel electrophoresis and MALDI-TOF analyses. The type of histological inflammation was used to define each condition in preterm labour cases (n = 125) and term not in labour cases (n = 22), and the amniotic fluid concentrations of interleukin-6, CXCL8, CXCL10 and prostaglandin F(2α) were also measured by specific immunoassays. Among preterm labour cases, 31 differentially expressed proteins were identified in chronic chorioamnionitis cases as compared to both acute chorioamnionitis and control cases. Importantly, glycodelin-A, which maintains maternal tolerance against an allogeneic fetus, was decreased in chronic chorioamnionitis, while haptoglobin was increased. We report the amniotic fluid proteome of chronic chorioamnionitis for the first time, and the findings herein strongly suggest that there is a pathophysiological association between the changes of immunomodulatory proteins in the amniotic fluid and chronic chorioamnionitis, a histological manifestation of maternal anti-fetal allograft rejection.

Abstract
Glycodelin is a glycoprotein named for its unique carbohydrate structure. Glycodelin is produced by the secretory endometrium during the late luteal phase and returns to baseline during menses of the ensuing cycle, whereas in conceptive cycles it rapidly increases. Although progesterone and possibly estradiol are required for glycodelin production, they are not directly involved in the synthesis and release of this protein. Their role may be development of the endometrial secretory glandular elements, whereas other factors are required to initiate and maintain glycodelin secretion. The pattern of relaxin secretion during the luteal phase and early pregnancy is similar to that of glycodelin, but their profiles have not been determined simultaneously. To investigate the relationship of relaxin and glycodelin, two studies were conducted. In the first study, relaxin, glycodelin, and ovarian steroids were measured in daily serum samples from nonconceptive and conceptive natural cycles. Profiles of relaxin and glycodelin were closely associated, with the onset of relaxin preceding glycodelin secretion by 1-2 days in nonconceptive cycles, and the pregnancy-associated increases in each hormone differing by about 2 days. The second study tested the hypothesis that relaxin stimulates glycodelin secretion. Samples were obtained from patients injected with human relaxin for 28 days. In subjects demonstrating ovarian cyclicity, glycodelin secretion was elevated, but it was not detected in subjects without ovarian cyclicity or in placebo-treated control subjects. This study reveals a close temporal and quantitative relationship between relaxin and glycodelin profiles in the late luteal phase and early pregnancy. It also demonstrates that relaxin administration can stimulate glycodelin production from a developed endometrium. This is the first report of a nonsteroidal ovarian factor that controls glycodelin secretion, and these results suggest a function for relaxin during early pregnancy. Glycodelin is a potent inhibitor of sperm zona pellucida binding by virtue of its extensive carbohydrate structure, but it is normally at a nadir in the periovulatory period. The data demonstrate that relaxin can stimulate glycodelin secretion throughout the menstrual cycle, including the periovulatory period, when relaxin-induced glycodelin secretion could have a contraceptive effect.

Abstract
This study was conducted to assess endometrial protection in women on a cyclical combined hormone replacement regimen with 1 mg norethisterone BP, and to evaluate the use of the bleeding pattern and serum alpha 2-PEG in monitoring the endometrial response to exogenous hormone therapy. Fifty-one postmenopausal women attending the Menopause Research Unit at Leicester Royal Infirmary, UK, completed the study. All patients were at least 1 year after the menopause, with an average of 26 months since the last menstrual period. All women were prescribed a regimen of two tablets of Hormonin (oestriol 0.27 mg, oestrone 1.4 mg, and oestradiol 0.6 mg) continuously, with 1 mg of norethisterone added for 12 days out of each 28-day treatment cycle. Menstrual diaries were collected and analysed. The secretory changes were assessed by histology, menstrual bleeding pattern and a biological marker of secretory activity (alpha 2-PEG). Withdrawal bleeding occurred on average on days 11, 12, 11, 12 and 13 on months 2, 3, 6, 9 and 12, respectively. There was a poor degree of consistency in the bleeding pattern. The level of alpha 2-PEG increased from the average baseline measurement of 2.7 ng/ml (S.D., 4.12) to 8.5 ng/ml (S.D., 4.16) after progestogen treatment. This rise, although significant, did not correlate with the uterine bleeding pattern. There was no statistically significant correlation between the level of alpha 2-PEG and endometrial histology. The findings highlight the fact that cycle predictability on HRT, as exemplified in this regimen, is poor. The level of alpha 2-PEG is a poor predictor of the endometrial histology and has a poor correlation with the day of onset of bleeding.
