Abstract
The aim of our laboratory-based study was to investigate the extent of delayed-onset cell death after cryopreservation in endothelial and epithelial cell lines of ovarian origin. We found differences in percentages of vital cells directly after warming and after cultivation for 48 to 72 h. A granulosa cell line of endothelial origin (KGN) and an epithelial cell line (OvCar-3) were used. In both DMSO-containing and DMSO-free protocols, significant differences in vitality rates between the different cell lines when using open and closed vitrification could be shown (DMSO-containing: KGN open vs. OvCar open, p = 0.001; KGN closed vs. OvCar closed, p = 0.001; DMSO-free: KGN open vs. OvCar open, p = 0.001; KGN closed vs. OvCar closed, p = 0.031). Furthermore, there was a marked difference in the percentage of vital cells immediately after warming and after cultivation for 48 to 72 h; whereas the KGN cell line showed a loss of cell viability of 41% using a DMSO-containing protocol, the OvCar-3 cell loss was only 11% after cultivation. Using a DMSO-free protocol, the percentages of late-onset cell death were 77% and 48% for KGN and OvCar-3 cells, respectively. Our data support the hypothesis that cryopreservation-induced damage is cell type and cryoprotective agent dependent.

Abstract
Background Polycystic ovary syndrome (PCOS) is linked to an elevated risk of psychological disorders, decreased quality of life and emotional distress. Serum cortisol as a potential stress marker has been found to be increased in women with PCOS. The aim of this study was to evaluate both saliva stress markers and subjective psychological distress in women with PCOS. Methods In a prospective case-control study, 31 PCOS women and 31 healthy controls were included. Salivary cortisol, and metanephrines were collected in the morning and in the evening. Emotional distress and quality of life were assessed by means of the Perceived Stress Scale (PSS-10) and the Short Form-36 (SF-36). Multivariable generalized linear models were applied to test the influence of various parameters on numerical outcome parameters. Results After correction for age and body mass index (BMI), there were no statistically significant differences of salivary biomarkers between PCOS women and healthy controls (p>0.05). PCOS patients revealed significantly higher increased PSS total scores and lower quality of life in all SF-36 modules apart from pain (p< 0.05). The PSS total score was positively correlated to prolactin in PCOS women (r= 0.450; p= 0.011). In overweight/obese PCOS patients, a higher BMI, a higher Ferriman Gallwey score and higher age significantly predicted the PSS total score (p< 0.05). Conclusion Stress measured by salivary biomarkers did not differ between PCOS women and healthy controls, whereas stress scores evaluated by questionnaires were significantly greater in women with PCOS. A higher BMI, hirsutism and a higher age seem to be the main modulators of subjective stress in PCOS. Prolactin might serve as a biomarker for chronic stress in PCOS women.

Abstract
PURPOSE In humans, granulosa cells (GCs) are part of the follicle and nourish the growing oocyte. GCs produce estrogen and, after ovulation, progesterone. They are embedded in a multicellular tissue structure of the ovary, which consists of a variety of different cell types that are essential for the physiological function of the ovary. However, the extent to which individual ovarian cell types contribute to overall functionality has not yet been fully elucidated. In this study, we aim to investigate the effects of co-culturing human granulosa cells with ovarian cancer cells on their progesterone and estrogen production in an in vitro model. METHODS After seeding, the cells were stimulated with 200 µM forskolin in DMEM for 72 h and the medium of the different cell culture experiments was collected. Subsequently, progesterone and oestradiol concentrations were determined using an Elisa assay. RESULTS Morphologically, it was striking that the cells self-organize and form spatially separated areas. Compared to culturing granulosa cells alone, co-culturing human granulosa cells together with the ovarian cancer cell line OvCar-3 resulted in a significant increase in progesterone production (20.3 ng/ml versus 50.2 ng/ml; p < 0.01). CONCLUSIONS Using a simple in vitro model, we highlight the importance of cellular crosstalk between different ovarian cells in a complex cellular network and that it strongly influences granulosa cell hormone production. This could have potential implications for the procedure of transplanting endocrine tissues after cryopreservation, as it highlights the importance of survival of all cells for the functionality of the transplanted tissue.

Abstract
OBJECTIVE To evaluate the long-term outcomes of children born to women with a short cervix and otherwise low risk for preterm birth, after antenatal exposure to vaginal progesterone vs placebo. METHODS This was a follow-up study of the Triple P trial, which randomized 80 low-risk women with a short cervix (≤ 30 mm) at 18-22 weeks' gestation to progesterone (n = 41) or placebo (n = 39). At 2 years of corrected age, children were invited for a neurodevelopmental assessment, using the Bayley Scales of Infant and Toddler Development, third edition (BSID-III), and a neurological and physical examination by an assessor blinded to the allocated treatment. Parents filled out the Ages and Stages Questionnaire, the Child Behavior Checklist (CBCL) and a general-health questionnaire. The main outcome of interest was mean BSID-III cognitive and motor scores. Additionally, a composite score of mortality and abnormal developmental outcome, including BSID-III ≤-1 SD, CBCL score in the clinical range and/or parental reported physical problems (at least two operations or at least two hospital admissions in the previous 2 years), was evaluated. Our sample size, dictated by the original sample of the Triple P trial, provided 80% power to detect a mean difference (MD) of 15 points (1 SD) between groups for the BSID-III tests. RESULTS Of the 80 children born to the randomized women, one in the progesterone group and two in the placebo group died in the neonatal period. Follow-up data were obtained for 59/77 (77%) children and BSID-III outcomes in 57 children (n = 28 in the progesterone group and n = 29 in the placebo group) born at a median gestational age of 38 + 6 weeks (interquartile range (IQR), 37 + 3 to 40 + 1 weeks) with a median birth weight of 3240 g (IQR, 2785-3620 g). In the progesterone vs placebo groups, mean BSID-III cognitive development scores were 101.6 vs 105.0 (MD, -3.4 (95% CI, -9.3 to 2.6); P = 0.29) while mean motor scores were 102.4 vs 107.3 (MD, -4.9 (95% CI, -11.2 to 1.4); P = 0.13). No differences were seen between the two groups in physical (including genital and neurological examination), behavioral and health-related outcomes. CONCLUSION In this sample of children born to low-risk women with a short cervix at screening, no relevant differences in neurodevelopmental, behavioral, health-related and physical outcomes were found between offspring exposed to vaginal progesterone and those exposed to placebo. © 2020 The Authors.

Abstract
Background Diagnosing urinary tract infections (UTIs) in nursing home residents is complex, as specific urinary symptoms are often absent and asymptomatic bacteriuria (ASB) is prevalent. The aim of this study was to assess the sensitivity of blood C-reactive protein (CRP) and procalcitonin (PCT), measured by point-of-care tests (PoCTs), to diagnose UTIs in this setting. Methods Elderly residents (≥65 years old) with a suspected UTI were recruited from psychogeriatric, somatic, or rehabilitation wards across 13 participating nursing homes. CRP and PCT were tested simultaneously in the same study participants. To assess the tests’ sensitivities, a stringent definition of “true” UTI was used that included the presence of symptoms, urinary leucocytes, a positive urine culture, and symptom resolution during antibiotic treatment covering isolated uropathogen(s). The original sample size was 440 suspected UTI episodes, in order to detect a clinically relevant sensitivity of at least 65% when calculated using the matched analysis approach to compare both PoCTs. Results After enrollment of 302 episodes (68.6% of the planned sample size), an unplanned and funder-mandated interim analysis was done, resulting in premature discontinuation of the study for futility. For 247 of 266 eligible episodes, all mandatory items required for the true UTI definition (92.9%) were available. In total, 49 episodes fulfilled our stringent UTI definition (19.8%). The sensitivities of CRP (cut-off, 6.5 mg/L) and PCT (cut-off, 0.025 ng/mL) were 52.3% (95% confidence interval [CI], 36.7–67.5%) and 37.0% (95% CI, 23.2–52.5%), respectively. Conclusions Our results indicate that CRP and PCT are not suitable tests for distinguishing UTI and ASB in nursing home residents. Clinical Trials Registration Netherlands Trial Registry NL6293.

Abstract
BACKGROUND Diagnosing urinary tract infections (UTI) in nursing home residents is complex, due to frequent non-specific symptomatology and asymptomatic bacteriuria. The objective of this study was to explore health care professionals' perceptions of the proposed use of inflammatory marker Point-Of-Care Testing (POCT) in this respect. METHODS We conducted a qualitative inquiry (2018-2019) alongside the multicenter PROGRESS study (NL6293), which assessed the sensitivity of C-reactive protein and procalcitonin POCT in UTI. We used semi-structured face-to-face interviews. The participants were physicians (n = 12) and nurses (n = 6) from 13 nursing homes in the Netherlands. Most respondents were not familiar with inflammatory marker POCT, while some used POCT for respiratory tract infections. Both the interview guide and the analysis of the interview transcripts were based on the Consolidated Framework for Implementation Research. RESULTS All respondents acknowledged that sufficiently sensitive POCT could decrease diagnostic uncertainty to some extent in residents presenting with non-specific symptoms. They primarily thought that negative test results would rule out UTI and justify withholding antibiotic treatment. Secondly, they described how positive test results could rule in UTI and justify antimicrobial treatment. However, most respondents also expected new diagnostic uncertainties to arise. Firstly, in case of negative test results, they were not sure how to deal with residents' persisting non-specific symptoms. Secondly, in case of positive test results, they feared overlooking infections other than UTI. These new uncertainties could lead to inappropriate antibiotics use. Therefore, POCT was thought to create a false sense of confidence. CONCLUSIONS Our study suggests that inflammatory marker POCT will only improve UTI management in nursing homes to some extent. To realize the expected added value, any implementation of POCT requires thorough guidance to ensure appropriate use. Developing UTI markers with high negative and positive predictive values may offer greater potential to improve UTI management in nursing homes.

Abstract
In reproductive medicine, the technique of rapid cooling becomes increasingly important for the preservation of tissue and cells. In order to protect the cells, incubation in different cryopreservation solutions is essential. The speed of the cooling process also makes a pivotal contribution to the success of this method. Using Flourescence Activated Cell Sorting (FACS), we investigated the impact of an open rapid and a closed rapid cooling technique on the vitality of human granulosa cells. Furthermore, we examined effects of the different solutions used for rapid cooling and warming before and after rapid cooling. We found a significant lower proportion of vital cells after rapid cooling compared to untreated controls independently of the technique and the tube size. However, we did not find any significant differences between open and closed rapid cooling. In both, a lower proportion of vital granulosa cells were found after incubation in rapid cooling solution only compared to warming solution only. Our results lend support to the conclusion that the difference of cooling-speed between open and closed rapid cooling is, in our settings, not crucial for the success of the procedure and that cryoprotective agents in the rapid cooling solutions have a higher potential to cause severe cell damage than agents used for warming.

Abstract
Objective Aim of the study was to investigate the expression of transforming growth factor-β1 (TGF-β1), a key regulator of the extracellular matrix composition, in the uterosacral ligaments (USLs) of women with pelvic organ prolapse (POP) compared with controls. We hypothesized that the expression pattern of TGF-β1 differs between postmenopausal women with or without POP. Methods Under ethical approval, USL samples were obtained from postmenopausal women undergoing vaginal hysterectomy for stage two or greater pelvic organ prolapse (cases, n = 70) and from postmenopausal women without pelvic organ prolapse undergoing vaginal hysterectomy for benign indications (controls, n = 30). Immunohistochemical staining was performed from paraffin embedded tissue using anti-TGF-β1 antibodies. The expression of TGF-β1 was evaluated by the pathologist, who was blinded to all clinical data. Results The expression of TGF-ß1 was similar in patients with symptomatic POP (89 % positive) and in controls (90 % positive) without any signs of prolapse (p = 0.091). Age-adjusted analysis did not significantly alter these results. Regarding POP-Q stages, TGF-ß1 was significantly more frequently expressed in severe prolapse cases compared to moderate/mild cases (POP-Q stage IV versus POP-Q stage II and III; p = 0.001). No significant association could be detected between TGF-ß1 expression and age, BMI and parity in cases with POP (p > 0.05). As published previously, advanced patients’ age as well as early menopausal age remained independent risk factors associated with POP in multiple logistic regression analysis (p = 0.001; p = 0.02). Conclusion Although our study detected POP-Q stage related alterations in USL composition and TGF-ß1 expression, there was no significant difference in the expression of TGF-β1 in cases with or without prolapse.

Abstract
STUDY QUESTION Are increased sVCAM-1 and sICAM-1 levels associated with tumor necrosis factor-alpha-converting enzyme (TACE) activity in endometriosis? SUMMARY ANSWER Here we provide the first functional evidence that induced TACE activity in human endometriotic epithelial cells is at least in part responsible for the enhanced release of sVCAM-1 from these cells. WHAT IS KNOWN ALREADY We and others have shown that serum-soluble (s)VCAM-1 levels are significantly higher in women with endometriosis, compared to disease-free controls. Experimental evidence exists suggesting a role of sICAM-1 and sVCAM-1 in the pathogenesis of endometriosis. TACE was identified as the protease responsible for phorbol 12-myristate 13-acetate (PMA)-induced VCAM-1 release in murine endothelial cells. Additionally, it has recently been shown that TACE is upregulated in the endometrial luminal epithelium of the mid-secretory phase in infertile women. STUDY DESIGN, SIZE, DURATION This study was conducted at the Tertiary Endometriosis Referral Center of the Medical University of Vienna. Samples from a total number of 97 women were collected between July 2013 and September 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS After complete surgical exploration of the abdominopelvic cavity, 49 women with histologically proven endometriosis and 48 endometriosis-free control women were enrolled. Each participating woman contributed only one sample of eutopic endometrium and normal peritoneum, and some of the women with endometriosis contributed samples of diverse types of endometriotic lesions (in total 52 ectopic samples). Among the 49 women with endometriosis, 36 matched samples of endometriotic lesions and corresponding eutopic endometrium were collected. In order to detect sVCAM-1 and TACE protein by ELISA, peritoneal fluid (PF) samples were collected from 44 cases and 32 controls during surgery. Expression of TACE mRNA was analyzed by qRT-PCR in 111 endometrium tissue samples (28 eutopic control samples, 33 eutopic samples from women with endometriosis, 50 ectopic samples from lesions) and 37 healthy peritoneum samples. Immunohistochemistry was performed in 123 tissue samples (39 eutopic control samples, 42 eutopic samples from women with endometriosis, 42 ectopic samples from lesions) and the relation between tissue TACE protein levels and sVCAM-1 secretion was examined. PMA-induced sVCAM-1 release, and TACE- and VCAM-1-transcripts or proteins were measured in an immortalized endometriotic epithelial cell line (11Z) pre-incubated either with TACE inhibitors or following TACE siRNA knockdown. MAIN RESULTS AND THE ROLE OF CHANCE Here, we demonstrate that TACE protein is overexpressed in epithelium of tissue samples of both eutopic endometrium and ectopic lesions of women with endometriosis compared to disease-free controls (P < 0.001 both) and that the overexpression of the protein in the lesions is due to activation of TACE gene transcription (P < 0.001). Moreover, epithelial TACE protein was significantly higher in ectopic samples than in corresponding eutopic tissue of women with the disease (P < 0.001). High endometrial tissue TACE protein expression correlated with higher serum sVCAM-1 levels (P < 0.05) but not with sICAM-1 levels. Inhibition of TACE either by TACE inhibitors or by TACE siRNA knockdown resulted in decreased PMA-induced shedding of sVCAM-1 in vitro (P < 0.005 or P < 0.01, respectively), but the TACE inhibitors did not affect transcription of TACE or VCAM-1. Additionally, we observed an upregulation of TACE in proliferative endometrial epithelium of infertile (P < 0.005), compared to fertile women. TACE was increased in infertile women with endometriosis (P = 0.051) but not in infertile women without endometriosis. LIMITATIONS, REASONS FOR CAUTION Albeit well characterized, our control population included women with other gynecologic diseases, which may have impacted the levels of sVCAM-1 and tissue TACE expression levels, e.g. benign ovarian cysts or uterine fibroids. Thus, the results of our analysis have to be interpreted carefully and in the context of the current experimental settings. WIDER IMPLICATIONS OF THE FINDINGS The dysregulation of TACE substrate shedding represents a promising yet relatively unexplored area of endometriosis progression and could serve as a basis for the development of new treatments of the disease.

Abstract
INTRODUCTION AND HYPOTHESIS Abnormalities of connective tissue structure or its repair mechanism may predispose women to pelvic organ prolapse (POP). We hypothesized that the expression of tenascin-X in the uterosacral ligament of postmenopausal women with symptomatic POP is increased compared with postmenopausal women without POP. Furthermore, we identified clinical risk factors associated with POP in our study population. METHODS We conducted a retrospective case-control study in which 33 postmenopausal women with symptomatic POP ≥ pelvic organ prolapse quantification system (POP-Q) stage II were matched with 33 postmenopausal women without POP. Studied tissue specimens were taken from hysterectomy specimens, and tenascin-X expression was investigated by immunohistochemistry. The immunohistochemical profile of the uterosacral connective tissue of cases and controls was compared. RESULTS Tenascin-X was expressed in 94% of POP cases and in 91% of controls. Our study failed to show any statistically significant differences in tenascin-X expression between women with and without POP (p = 0.64). However, tenascin-X was significantly more expressed in cases with severe prolapse (POP-Q stage IV) compared with moderate prolapse stages (POP-Q stage II and III) (p = 0.001). Advanced patient age as well as early menopausal age remained independent risk factors associated with POP in multiple logistic regression analysis (p = 0.001). CONCLUSION No difference could be demonstrated between tenascin-X expression in patients with or without POP. Tenascin-X does not seem to play a major role in the pathogenesis of POP in postmenopausal women.

Abstract
Recent research has emphasized the potential unfavorable effects of declining testosterone (T) levels in men and the putative beneficial effect of androgen therapy in select women. Some controversy surrounding the mechanism of action and the effects of T on endothelium remains. In this study, we evaluated the mechanism of T action on pooled primary Human Umbilical Vein Endothelial Cells (HUVEC) of mixed gender by focusing on two important processes, proliferation and migration. In our in vitro model system, we found that only the supra-physiological dose of T affected these two processes irrespective of the ratio of male to female cells in the pools. At a concentration of 1 μM, T downregulated the proliferation of HUVEC by inducing arrest in the G1 cell cycle phase in an Androgen Receptor (AR)-independent manner. We show that treatment with 1 μM T also induced downregulation of HUVEC migration. This process was AR-dependent and was associated with persistent phosphorylation of ezrin, radixin and moesin. Regardless of the mechanism of action, the treatment of HUVEC with both supra- and physiological doses of T was associated with posttranscriptional stabilization of the AR upon ligand binding.

Abstract
INTRODUCTION Cryopreservation of ovarian tissue is an essential step in Ovarian Tissue Banking. In order to prevent the formation of ice crystals, typically the tissue is slowly frozen using a cryoprotectant. As an alternative the method of ultra-fast freezing by vitrification becomes more attention for freezing ovarian tissue because it has successfully been used for oocytes, embryos and sperm. However the impact of vitrification on granulosa cells, which are an essential part of ovarian tissue is uncertain. AIM In this study, we have therefore analysed the influence of vitrification on the survival rates of granulosa cells, the impact of DMSO or ethylenglycol containing vitrification protocols and investigated to what extent the gene expression of apoptosis- and temperature-sensitive genes changes. MATERIAL AND METHODS We used the human granulosa cell line KGN as a model for human granulosa cells and determined the survival rate and cell cycle stages by FACS analyses. The change in gene expression was determined by quantitative PCR analyses. RESULTS Our results show that vitrification is possible in granulosa cells but it reduces cell viability and leads to fluctuations in the cell cycle. The DMSO containing protocol results in a lower amount of dead cells than the ethylenglycol containing protocol. Gene expression analysis reveals that TNF-alpha expression is strongly increased after vitrification, while other apoptosis or temperature-related genes seem to stay unaffected. CONCLUSION We conclude that vitrification influences the viability of human granulosa cells. Furthermore, our results suggest that this could be mediated by a change in TNF-alpha gene expression.

Abstract
Like other RECQ helicases, WRN/RECQL2 plays a crucial role in DNA replication and the maintenance of genome stability. Inactivating mutations in RECQL2 lead to Werner syndrome, a rare autosomal disease associated with premature aging and an increased susceptibility to multiple cancer types. We analyzed the association of two coding single-nucleotide polymorphisms in WRN, Cys1367Arg (rs1346044), and Arg834Cys (rs3087425), with the risk, age at onset, and clinical subclasses of breast cancer in a hospital-based case-control study of an Austrian population of 272 breast cancer patients and 254 controls. Here we report that the rare homozygous CC genotype of rs1346044 was associated with an approximately two-fold elevated breast cancer risk. Moreover, patients with the CC genotype exhibited a significantly increased risk of developing breast cancer under the age of 55 in both recessive and log-additive genetic models. CC patients developed breast cancer at a mean age of 55.2 ± 13.3 years and TT patients at 60.2 ± 14.7 years. Consistently, the risk of breast cancer was increased in pre-menopausal patients in the recessive model. These findings suggest that the CC genotype of WRN rs1346044 may contribute to an increased risk and a premature onset of breast cancer.

Abstract
BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is the most serious complication of IVF/ICSI therapy. The pathophysiology and etiology of the disease is still not fully clarified. METHODS To assess whether polymorphisms of the VEGF/VEGF-receptor system contribute to the occurrence of ovarian hyperstimulation syndrome (OHSS), we performed a retrospective analysis of 116 OHSS patients, and 124 female controls. The following SNPs were genotyped: Rs2071559 (VEGFR2-604); rs2305948 (VEGFR2-1192); rs1870377 (VEGFR2-1719); rs2010963 (VEGF-405); and rs111458691 (VEGFR1-519). Odds ratios (ORs) were estimated with a 95% confidence interval (CI). Linkage disequilibrium (LD) analysis was performed in the three loci of the VEGFR2 gene. RESULT We found an overrepresentation of the T allele of the VEGFR1-519 polymorphism in OHSS patients (P = 0.02, OR: 3.62, CI: 1.16 - 11.27). By genotype modeling, we found that polymorphism of VEGFR1-519 and VEGF-405 showed significant differences in patients and controls (p = 0.02, OR: 3.79 CI: 1.98 - 11.97 and p = 0.000005, OR: 0.29, CI: 0.17 - 0.50). LD analysis revealed significant linkage disequilibrium in VEGFR2. CONCLUSION Polymorphisms in the VEGFR2 gene and in the VEGF gene are associated with the occurrence of OHSS. This strengthens the evidence for an important role of the VEGF/VEGF- receptor system in the occurrence of OHSS.

Abstract
Low-grade endometrial stromal sacomas (ESS) are estrogen-sensitive tumors. Polymorphic variation in the CYP19 gene can affect estrogen synthesis by increasing aromatase activity resulting in elevated levels of estrone and estradiol. We examined the polymorphism 1558 C > T in he aromatase gene (CYP19A1) in a series of 20 low-grade endometrial stromal sarcomas. Archival formalinfixed and paraffin-embedded material was analyzed with a fast real-time PCR system. The homozygous C/T- and the homozygous mutant T/T-genotypes were detected in 10/20 (50%) and 7/20 (35%) samples, respectively. Polymorphism 1558 C > T in the aromatase gene may represent a high-risk allele with increased local estrogen levels.

Abstract
BACKGROUND The stem cell marker Octamer-4 (OCT-4) is expressed in human endometrium. Menstrual cycle-dependency of OCT-4 expression has not been investigated to date. METHODS In a prospective, single center cohort study of 98 women undergoing hysteroscopy during the follicular (n = 49) and the luteal (n = 40) phases of the menstrual cycle, we obtained endometrial samples. Specimens were investigated for OCT-4 expression on the mRNA and protein levels using reverse transcriptase polymerase chain reaction (RT-PCR) and immunohistochemistry. Expression of OCT-4 was correlated to menstrual cycle phase. RESULTS Of 89 women sampled, 49 were in the follicular phase and 40 were in the luteal phase. OCT-4 mRNA was detected in all samples. Increased OCT-4 mRNA levels in the follicular and luteal phases was found in 35/49 (71%) and 27/40 (68%) of women, respectively (p = 0.9). Increased expression of OCT-4 protein was identified in 56/89 (63%) samples. Increased expression of OCT-4 protein in the follicular and luteal phases was found in 33/49 (67%) and 23/40 (58%) of women, respectively (p = 0.5). CONCLUSIONS On the mRNA and protein levels, OCT-4 is not differentially expressed during the menstrual cycle. Endometrial OCT-4 is not involved in or modulated by hormone-induced cyclical changes of the endometrium.

Abstract
OBJECTIVE TNF-alpha G308A, IL-6 G174C and IL-10 G1082A polymorphisms have recently been associated with preeclampsia (PE). The aim of this study was to clarify whether the occurrence of TNF-alpha, IL-6 and IL-10 polymorphisms is increased in women of our population with PE in a previous pregnancy. METHODS A retrospective, controlled, open, multicenter study was carried out in 107 women with a history of PE and 107 women with uncomplicated pregnancies. Smears from buccal gingival cells were analyzed for the polymorphisms of TNF-alpha, IL-6 and IL-10 by hybridization on microarrays. Statistical significance was calculated by the chi-quadrant test. RESULTS Heterozygocity for the gene polymorphisms did not occur more often in preeclamptic women compared with controls (TNF-alpha: 29.0% versus 24.3%, p>0.05; IL-6: 46.7% versus 51.4%, p>0.05; or IL-10: 49.5% in each). Moreover, there was no significant difference between preeclamptics and controls with regard to homozygocity for TNF alpha (1.9% versus 3.7%, p>0.05); IL-6 (17.8% versus 13.1%, p>0.05); and IL-10 (30.8% versus 32.7%, p>0.05). CONCLUSION In contrast to the findings of some other investigators, gene polymorphisms do not seem to be important in our population for development of PE.

Abstract
Estrogen replacement therapy is associated with a reduced risk of colon cancer. Therefore, we evaluated the following ten estrogen metabolism-associated single-nucleotide polymorphisms (SNPs) by sequencing-on-chip technology using solid-phase polymerase chain reaction (PCR) on oligonucleotide microarrays: catechol-O-methyltransferase (COMT) Val158Met G-->A, 17-beta-hydroxysteroid dehydrogenase type 1 (HSD17) vlV A-->C, cytochrome P-450 (CYP) 17 A2 allele T-->C, CYP1A1 MspI RFLP T-->C, CYP1A1 Ile462Val A-->G, CYP19 Arg264Cys C-->T, CYP19 C1558T C-->T, CYP 1B1 Leu432Val, CYP1B1 Asn453Ser, and estrogen receptor (ER) alpha IVS1 -401-->C in 76 patients with a family history of colon cancer and 722 healthy controls. Using stepwise logistic regression models, we found that none of the investigated SNPs is associated with a family history of colon cancer in a univariate and multivariate logistic regression model. In addition, when all two-way interactions of the investigated SNPs were ascertained, no significant interactions between SNPs were observed. In conclusion, we found no association between the carriage of one or multiple SNPs of the estrogen metabolism and a family history of colon cancer.

Abstract
OBJECTIVE Androgens are thought to play an important role in various reproductive functions. We evaluated the association between a common polymorphism of the steroid 5-alpha-reductase type 2 gene (SRD5A2) involved in androgen metabolism and the timing of menopause. STUDY DESIGN Three hundred and twenty-three consecutive women were included in this cross-sectional study. The common exon 1 Valine/Leucin polymorphism of the SRD5A2 gene was analyzed using a microarray-based system. RESULTS No significant association between the SRD5A2 polymorphism and age (years) at natural menopause was ascertained. There were no significant differences in the background characteristics of the subjects among SDR5A2 genotypes including the number of full term pregnancies, age at first delivery, BMI, personal or family history of breast cancer, smoking status and personal history of recurrent abortion. A multivariate regression analysis showed that the number of full term pregnancies, but not smoking, an increased body mass index, or a history of breast cancer significantly influenced timing of natural menopause. CONCLUSION In the present study the number of full term pregnancies, but not the common V89L SRD5A2 polymorphism, is the only significant predictor for the timing of natural menopause in Caucasian women.

Abstract
The number of reports investigating disease susceptibility based on the carriage of low-penetrance, high-frequency single nucleotide polymorphisms (SNPs) has increased in recent years. Evidence is accumulating defining specific individual variations in breast cancer susceptibility. Genetic variations of estradiol and xenobiotics metabolisms as well as genes involved in cell-cycle control have been described as significant contributors to breast cancer susceptibility, with variations depending on ethnic background and co-factors such as smoking and family history of breast cancer. In sum, the highest level of evidence to date linking SNPs and breast cancer comes from nested case-control studies within the prospective Nurses' Health Study. These data establish seven SNPs - hPRB +331G/A, AR CAG repeat, CYP19 (TTTA)10, CYP1A1 MspI, VDR FOK1, XRCC1 Arg194Trp and XRCC2 Arg188His - as small but significant risk factors for spontaneous, non-hereditary breast cancer. In addition, meta-analysis of data in the literature establishes the TGFBR1*6A, HRAS1, GSTP Ile105Val and GSTM1 SNPs as low-penetrance genetic risk factors of sporadic breast cancer. The clinical consequences of such a risk elevation may be detailed instruction of the patient as to general measures of breast cancer prevention such as a low-fat diet, optimization of body mass index, physical exercise, avoidance of alcohol and long-term hormone replacement therapy, and participation in a breast cancer screening program between the ages of 50 and 70 years. Specific surgical or drug interventions such as prophylactic mastectomy and oophorectomy or prophylactic intake of tamoxifen are not indicated based on SNP analysis at this time.

Abstract
OBJECTIVE Genetic as well as hormonal factors are known to influence the development and clinical course of endometriosis. We aimed to investigate the association among 10 single nucleotide polymorphisms (SNPs) involved in the estrogen metabolism and endometriosis and to develop a multiple genetic model. METHODS In a case-control study, we investigated the genotype frequencies of 10 estrogen metabolizing SNPs in 32 patients with endometriosis and 790 healthy controls using sequencing-on-chip-technology with solid-phase polymerase chain reaction on oligonucleotide microarrays: catechol-O-methyltransferase, Val158Met G->A, 17-beta-hydroxysteroid dehydrogenase type 1 (HSD17), vlV A->C, cytochrome P450 (CYP), 17 A2 allele T->C, CYP1A1 MspI RFLP T->C, CYP1A1 Ile462Val A->G, CYP19 Arg264Cys C->T, CYP19 C1558T C->T, CYP 1B1 Leu432Val, CYP1B1 Asn453Ser, and estrogen receptor alpha IVS1 -401>C. Associations and 2-way interaction models between SNPs were calculated by stepwise logistic regression models. RESULTS In a univariate model, HSD17 vlV A->C was associated with a significantly increased risk of endometriosis (P = .004; odds ratio 3.9, 95% confidence interval 1.6-9.8). When all 2-way interactions of investigated SNPs were ascertained, no significant interactions among SNPs were observed. In a multivariate model, HSD17 vlV A->C was also significantly associated with endometriosis (P = .002). CONCLUSION We present data on multiple SNPs in patients with endometriosis indicating an association between HSD17 gene variation and the disease. Although not able to demonstrate interaction models of SNPs, we provide evidence of HSD17 vlV A->C as a low penetrance genetic marker of endometriosis. LEVEL OF EVIDENCE II-2.

Abstract
BACKGROUND Lifestyle parameters, personal history and genetic factors are thought to affect the timing of natural menopause in humans. Based on their biological function, estrogen-metabolizing gene polymorphisms have been regarded as candidate genes for early menopause. METHODS In the present cross-sectional, multi-centre study, we analysed nine single nucleotide polymorphisms of six estrogen-metabolizing genes [three estrogen-synthesizing genes, i.e. 17-beta-hydroxysteroid dehydrogenase type 1 (17-beta HSD), cytochrome P-450 (CYP) 17 and CYP19; and three estrogen-inactivating genes, i.e. catechol-O-methyltransferase (COMT), CYP1A1 and CYP1B1] by sequencing-on-chip-technology in 1360 Caucasian women with natural menopause. Women's lifestyle parameters, reproductive and personal histories were ascertained. RESULTS Carriage of at least one mutant allele of the CYP1B1-4 Asn453Ser A--> G polymorphism (P = 0.004) and the number of full-term pregnancies (P < 0.001) were found to be independently associated with age at natural menopause. Women with at least one polymorphic allele of CYP1B1-4 experienced natural menopause earlier than non-carriers of the polymorphism [mean (SD) 48.6 (5.0) versus 49.4 (4.3) years]. Women with no, one, two and three or more full-term pregnancies experienced natural menopause at 48.5 (5.0), 48.8 (4.8), 49.5 (4.2) and 49.6 (4.6) years, respectively. CONCLUSION We present the most comprehensive data on estrogen-metabolizing gene polymorphisms and timing of natural menopause to date. The number of full-term pregnancies and the CYP1B1-4 polymorphism are significant predictors of timing of natural menopause in Caucasian women.

Abstract
OBJECTIVE Deficiency of the gene encoding endothelial nitric oxide synthase, i.e. Nos3, has been reported to be associated with late menarche, reduced ovulation rates, fewer deliveries, and earlier onset of menopause in a mouse model. METHODS We assessed the Glu298Asp and the T-786C polymorphisms of Nos3 in 87 consecutive healthy postmenopausal women by pyro- and capillary-sequencing, respectively. Results were correlated with age at menarche and natural menopause, number of miscarriages and live births, as well as body mass index (BMI) and smoking habits. RESULTS Allelic frequencies of the Glu298Asp polymorphism of Nos3 were 121 (69.5%) and 53 (30.5%) for the wild-type G allele and the mutant T allele, respectively. Forty-one women (47.1%) were homozygote wild-type (G/G), 39 (44.9%) were heterozygote (G/T), and 7 (8.0%) were homozygote mutant (T/T). Allelic frequencies of the T-786C polymorphism of Nos3 were 105 (60.6%) and 69 (39.4%) for the wild-type T allele and the mutant C allele, respectively. Thirty-three women (38.0%) were homozygote wild-type (T/T), 39 (45.1%) were heterozygote (T/C), and 15 (16.9%) were homozygote mutant (C/C). Presence of at least one mutant allele of the Glu298Asp or the T-786C polymorphisms of Nos3 were not associated with age at menarche, natural menopause, and number of miscarriages and deliveries. BMI above 27 kg/m2 and smoking were associated with earlier onset of natural menopause (47.8 years versus 50.2 years (P = 0.01) and 46.8 years versus 49.8 years (p = 0.02)). CONCLUSIONS Our data show that smoking and increased BMI, but not Glu298Asp or the T-786C polymorphisms of Nos3, are associated with an early onset of natural menopause.

Abstract
The number of reports investigating disease susceptibility based on the carriage of low-penetrance, high-frequency polymorphisms has steadily increased over the last years. Evidence based on meta-analyses of individual case-control studies is accumulating, defining specific individual variations in disease susceptibility. For example, genetic variations of the estradiol metabolism have been described as significant contributors to disease susceptibility with variations depending on ethnic background. In the field of obstetrics and gynecology, the genetic contribution of polymorphic markers to a series of disorders has been characterized. These disorders include recurrent pregnancy loss, pre-eclampsia, endometriosis, breast cancer, and hormone replacement therapy (HRT)-related complications such as thrombosis. Among other genetic markers, thrombophilic genetic variants, such as the Factor V Leiden and prothrombin G20210A polymorphisms, as well as genetic variants of cytochrome P450 (CYP) enzymes, for example, CYP19 and CYP1B1, have been established as genetic risk markers and disease modifiers of recurrent and sporadic pregnancy loss and HRT-independent and -dependent breast cancer, respectively. In addition, meta-analyses of data in the literature established the TGFBR1*6A, GSTP I105V, and TP53 R72P polymorphisms, as well as the GSTM1 gene deletion as low-penetrance genetic risk factors of sporadic breast cancer. With respect to genetic modulation of therapeutic effects, beneficial effects of estrogen replacement therapy and HRT are modulated by the carriage of single nucleotide polymorphisms, for example, osteoprotection and blood lipid changes by the estrogen receptor-alpha (ER-a) PvuII polymorphism. Polymorphisms of the catechol-O-methyltransferase (COMT), ER-alpha, IL-1 receptor antagonist, and Factor V genes have been demonstrated to modulate the timing of natural menopause. Lastly, a strong genetic contribution of polymorphisms to the development and the clinical course of endometriosis has been established with data pointing to polymorphisms of the COMT, GST, NAT-2, and ER-alpha genes as susceptibility markers. In summary, the available evidence points to a number of polymorphisms of a wide variety of genes as strong hereditary determinants of the susceptibility to benign and malignant gynecologic and obstetric conditions.

Abstract
A simple, sensitive, nonradioactive method for measuring carbon monoxide (CO) in cell culture supernatant is described. Dissolved CO reacts with hemoglobin (Hb) to carboxyhemoglobin (HbCO) in a modified Conway cell. HbCO is quantified by spectrophotometric analysis, and total concentration of CO given in microg CO/l cell culture supernatant is mathematically calculated. Furthermore, we compared our newly developed method with a recently published method. Confluent human umbilical vein epithelial cells (HUVEC) were incubated with 10(-6) M hydrocortisone known to induce heme oxygenase-2 protein and transcript expression for 4 h and CO production was measured. Levels following hydrocortisone treatment were significantly enhanced compared to controls when using our newly developed technique (p<0.05), whereas only a nonsignificant trend could be observed using the recently published method. We conclude that this nonradioactive technique to quantify CO is more sensitive than previous ones, thereby allowing to measure even physiologic quantities of CO in aqueous solutions.

Abstract
BACKGROUND Genes encoding enzymes involved in estrogen metabolism are held to be candidate genes for associations with breast disease. In these candidate genes, no critical combination of single-nucleotide polymorphisms (SNPs) for assessing breast carcinoma risk has been reported to date. METHODS In a large case-control study, the authors investigated 10 estrogen-metabolizing SNPs in 396 patients with breast carcinoma, 154 patients with fibroadenoma, and 1936 healthy control patients without breast carcinoma in their personal history. The following 10 SNPs were analyzed using sequencing-on-chip technology via a solid-phase polymerase chain reaction assay performed on oligonucleotide microarrays: catechol-O-methyltransferase Val158Met G-->A, 17-beta-hydroxysteroid dehydrogenase type 1 vIV A-->C, cytochrome P-450 (CYP) family 17 A2 allele T-->C, CYP1A1-1 MspI restriction fragment length polymorphism (RFLP) T-->C, CYP1A1-2 Ile462Val A-->G, CYP19-1 Trp39Arg T-->C, CYP19-2 Arg264Cys C-->T, CYP19-3 Cys1558Thr C-->T, steroid-5-alpha reductase type 2 Val89Leu G-->C, and vitamin D receptor BsmI RFLP. A total of 21,350 genotypes were evaluated. Associations and two-way interaction models were calculated using stepwise logistic regression. RESULTS In a multiple model, CYP1A1-1 (P = 0.004) and CYP1A1-2 (P = 0.03) were found to be associated with significantly decreased and increased risks of breast carcinoma, respectively. When two-way interactions involving investigated SNPs were ascertained, no significant interactions among polymorphisms were noted. Comparison of patients with fibroadenoma with control patients revealed significantly increased and decreased risks of fibroadenoma when the mutant alleles of CYP17 (P = 0.02) and CYP1A1-1 (P = 0.04), respectively, were present. CONCLUSIONS The authors obtained the first SNP data indicating that CYP17 and CYP1A1-1 play a role in the pathogenesis of fibroadenoma. Although the authors were not able to develop interaction models involving SNPs, they did provide evidence that CYP1A1 is a low-penetrance susceptibility gene with respect to breast carcinoma in a large series of Caucasian women.

Interleukin (IL)-6 has been implicated in the etiology of endometriosis. A single nucleotide polymorphism (SNP) at position -174 in the IL-6 gene promoter appears to influence IL-6 transcription rates in vitro and basal IL-6 levels in vivo. We determined the genotype and the allele frequencies of the -174 IL-6 promoter polymorphism and the corresponding IL-6 serum levels in women with endometriosis. The pyrosequencing technique was used to assess the IL-6 genotypes in 94 women with histologically confirmed endometriosis (study group). A series of 70 healthy women without history of uterine disease served as clinical controls (control group).Allele frequencies for the G allele among women with and without endometriosis were 59.6% and 55.0%, respectively (P =.430; odds ratio [OR] 0.83, 95% confidence interval [CI] 0.53, 1.29). Homozygotes for the protective allele C were present in 17.0% of women with endometriosis and in 18.6% of controls were homozygous for the protective allele C (P =.797; OR 0.90, 95% CI 0.40, 2.02). When patients with various disease manifestations were compared, we found an association between the -174 G allele and chocolate cysts (P =.037). Serum levels of IL-6 were significantly higher in women with endometriosis than in controls (P <.001), with highest levels in women with chocolate cysts. There was no association between serum IL-6 levels and IL-6 genotype. The IL-6 promoter polymorphism -174 G/C does not contribute significantly to overall disease susceptibility but does predispose the carrier to distinct endometriosis with chocolate cysts. A genetically determined high IL-6 response might play a pathogenic role in this disease condition.

Abstract
We analyzed the p53 mutational status, mRNA and protein expression in 24 human breast carcinoma cell lines. Following measurement of their DNA content with flow cytometry, we ascertained the copy numbers of the centromere of chromosome 17 (cen17) and p53 with fluorescence in situ hybridization (FISH). A functional yeast assay (FASAY) was used to screen for inactivating mutations. Positive results were subsequently verified by DNA sequencing. Finally, we assessed the mRNA expression with a competitive reverse transcription-polymerase chain reaction (RT-PCR) assay and the protein expression with immunocytochemical staining, western blot, and quantitative flow cytometry. The DNA content of the cell lines ranged from 0.85 to 2.58. Nine cell lines had concordant copy numbers (between two and four) of p53 and cen17, whereas 12 had more, and three less cen17 than p53 copies. The FASAY was successful in all but one cell line and revealed the presence of mutated alleles in 16 of them, 13 cell lines expressed only the mutated, and three both the mutated and the wild-type alleles. The mutations were comprised of 11 missense, two nonsense, and three frameshift mutations. Immunocytochemical staining, western blot and quantitative flow cytometry yielded comparable p53 protein expression results. However, both the mRNA and the protein expression levels varied considerably in the different cell lines and no consistent pattern with regard to the respective p53 mutational status became evident. The results obtained in these breast carcinoma cell lines indicate that no clear-cut linear relationship exists between the p53 mutational status and the extent of its respective mRNA and protein expression. Therefore, direct DNA analyses and functional assays remain the only methods for the reliable detection of p53 mutations.

Abstract
OBJECTIVE Experimental data indicate that interleukin (IL)-1 plays a role in the pathogenesis of endometriosis. We determined the genotype and the allele frequencies of the IL1B exon 5 polymorphism and the corresponding IL-1beta serum levels in women with endometriosis. METHODS We genotyped 92 women with surgically and histologically confirmed endometriosis and 69 controls without history of endometriosis. Both groups were of middle European genetic background for the IL1B exon 5 polymorphism (at position +3954). Genotyping was performed by pyrosequencing. IL-1beta serum levels were analyzed by a commercially available enzyme-linked immunosorbent assay. RESULTS Allele frequencies in women with endometriosis and controls were 76.6% and 76.8%, respectively, for the E1 allele (wild type) and 23.4% and 23.2%, respectively, for the E2 allele (polymorphic) (odds ratio 1.01; P > .99). The investigated polymorphism of the IL-1beta gene was not correlated with IL-1beta serum levels. CONCLUSIONS We did not find an association between the IL1B exon 5 polymorphism, endometriosis, or increased serum IL-1beta levels.

Abstract
BACKGROUND Catechol-O-methyltransferase (COMT) is the principal enzyme in the conjugation pathway for hydroxylated estrogens. We hypothesize that blood 17beta-estradiol (E(2)) and estrone (E(1)) levels in postmenopausal women receiving an oral E(2) preparation are dependent on the enzyme activity of COMT. METHODS To determine the influence of this enzyme on E(2) serum levels three groups of 12 selected from 159 healthy normotensive postmenopausal women were selected according to their codon 158 COMT genotype (COMT(HH), COMT(HL), COMT(LL)) which is known to be associated with enzyme activity. All selected women received one 2 mg tablet estradiol valerate and blood samples were taken before treatment and after 1, 3 and 48 h. RESULTS After 3 h the serum levels of E(2) were significantly higher in women with the COMT(LL) genotype (median 69 pg/ml, range 58-91) and the COMT(HL) genotype (median 69 pg/ml, range 43-84) compared with women with the COMT(HH) genotype (median 45 pg/ml, range 15-68, P < 0.005). In a univariate analysis of variance, considering age, body weight, and COMT genotype, body weight (P = 0.034) and COMT genotype (P < 0.001) were independently related to the increase of serum E(2) levels, whereas age was not. CONCLUSIONS Our data demonstrate that serum E(2) levels significantly correlate with the COMT genotype. Differences in COMT genotype might be involved in causing variable effects of estrogens on diseases such as hormone-dependent cancers, coronary heart disease and on efficacy of hormone replacement therapy.

Abstract
Leider besteht für diesen Artikel keine Zusammenfassung. Als Einstieg stellen wir den Textanfang zur Verfügung. Mehr als ein Jahrzehnt dauert bereits die wissenschaftliche Auseinandersetzung zwischen deutschen und österreichischen Endokrinologen bzw. Biochemikern, ob eine individuelle Hormonersatztherapie (HRT) sinnvoll ist und wie sie konkret aussehen soll. Dieses Thema wird nicht nur durch rezente Untersuchungen [1] aktualisiert, die klar belegen, dass die behandelten Frauen zu einem hohen Prozentsatz mit ihrer HRT unzufrieden sind und sie – vor allem wegen hyperöstrogenämischen Symptomen – nach relativ kurzer Zeit wieder beenden, sondern auch durch die HERS [2] und die Studie der Nurses’ Health Initiative [3], die sich von ihrem Design durch eine völlig unreflektierte Hormonverordnung auszeichnen. Die dabei vor allem gleich am Beginn auftretenden kardiovaskulären Probleme deuten bereits auf eine genetische Risikodisposition hin, in die stereotyp hineinsubstituiert wurde.

Abstract
Interleukin (IL)-1 has been shown to induce peritoneal adhesions. We determined the IL-1 receptor antagonist (IL-1RN) genotype with respect to the two most common variant alleles IL-1RN*2 and IL-1RN*3 in Caucasian women with peritoneal adhesions. One hundred seven women with surgically verified peritoneal adhesions and 79 controls without peritoneal adhesions served as controls. Univariate analysis showed an increased risk for peritoneal adhesions for Caucasian women carrying the mutant IL-1RN*2 allele (OR: 2.1; 95% CI: 1.3-3.4; P = 0.004). Multiple logistic regression analysis demonstrated an increased risk for peritoneal adhesions, which is independent of previous abdominal surgery and endometriosis. Our data suggest that IL-1RN*2 allele carriers have an increased risk for adhesion formation.

Abstract
To explore whether having the mutant tumor necrosis factor (TNF)2 (G-308*A) and TNFA-A (G-238*A) alleles in the TNF-alpha gene promotor region is higher in women with endometriosis, we determined the respective genotype and allele frequencies in a retrospective case-control study. Polymerase chain reaction was performed to identify the G-308A and G-238A promotor polymorphisms in 92 women with surgically and histologically confirmed endometriosis. A series of 69 healthy women without a history of endometriosis served as clinical controls. The allele frequencies of the TNF2 polymorphism were 0.13 and 0.16 in women with endometriosis and in the control group, respectively, and the frequencies of the TNFA-A polymorphisms in women with endometriosis and in the control group were 0.04 and 0.05, respectively, with no significant difference between the study and control groups. The TNF2 polymorphism was present in the homozygous form (TNF(2/2)) in 4.3% of women with endometriosis and in 2.9% of controls (P=.7). No TNFA-A homozygotes (TNFA(A/A)) were detected. We studied TNF-alpha promotor gene variants among women with endometriosis and found that having the G-308A TNF-alpha and the G-238A TNF-alpha polymorphism was not associated with endometriosis in a white population.

Abstract
PURPOSE The purpose of the present study was to identify the expression of estrogen and progesterone receptor mRNA and of estrogen and progesterone receptor protein in the conjunctiva of healthy women. METHODS Specimens of conjunctival tissue of 10 premenopausal women (age range, 13-38 years) were obtained during ophthalmic surgery in patients under general anesthesia. Specimens of approximately 4 mm(2) were taken from superior, nasal, or temporal bulbar conjunctiva adjacent to the bulbus and were immediately deep frozen with liquid nitrogen. Four women underwent strabismus surgery, two had phacoemulsification, and four had vitrectomy. Only three women were taking oral contraceptives. The expression of estrogen receptor (ER)-alpha, ERbeta, and progesterone receptor (PR) mRNA was analyzed by RT-PCR. Western blot analysis on nuclear extracts was performed with the anti-ERalpha mouse monoclonal antibody AB-15, the anti-ERbeta mouse monoclonal antibody 6B12, and the anti-PR mouse monoclonal antibody PgR 636. RESULTS In two samples, ERalpha, ERbeta, and PR mRNAs were not accessible because of highly degraded RNA. In the remaining eight samples, an appearance rate of 100% was obtained for all three mRNAs. Similarly, an appearance rate of 100% was obtained for ERalpha, ERbeta, and PR protein in nine tissue samples accessible for analysis; one sample could not be analyzed due to a low amount of tissue. CONCLUSIONS This study confirms the existence of estrogen and progesterone receptors in the human conjunctiva of premenopausal females. Because the proteins of estrogen and progesterone were also found in this study's specimens, the data indicate that the conjunctiva is a target site for sex steroids. Future studies are needed to elucidate the role of these receptors in ocular diseases involving the conjunctiva.

Abstract
Steroid hormone receptor co-factors are abundantly expressed in the uterus in order to modify steroid hormone receptor action, either leading to activation or repression of transcription in the endometrium. However, the role of co-factors in remodelling of the human endometrium has not been established. We therefore endeavoured to evaluate the presence of the co-activator SRC (steroid receptor co-activator)-1 and the co-repressors N-CoR (nuclear receptor co-repressor) and steroid co-repressor SMRT (silencing mediator of retinod and thyroid) receptors in the human endometrium during the different phases of the menstrual cycle. By using a real-time RT-PCR assay, we showed that SRC-1, N-CoR and SMRT mRNA are expressed in human endometrium during all phases of the menstrual cycle, as well as in inactive endometrium. Moreover, endometrial expression of SRC-1 and N-CoR mRNA increased during menstruation when compared with the other phases of the menstrual cycle (P < 0.001). Immunohistochemistry demonstrated that SRC-1 and N-CoR stain positive in the glandular epithelium and stroma in menstrual phase endometrium. The staining was weak in proliferative and secretory endometrium and absent in inactive endometrium. Our results suggest that differential expression of endometrial steroid receptor co-factors probably play a role in the regulation of human endometrium remodelling.

Abstract
PURPOSE Catechol-O-methyltransferase (COMT) inactivates the estradiol metabolites, 2-hydroxy and 4-hydroxy catechols, which have been implicated in the pathogenesis of endometriosis. A COMT valine to methionine polymorphism (G-to-A) in exon 4 of the COMT gene is polymorphic in the human population, with 25% of Caucasians being homozygous for the low-activity allele (COMT-L) of the enzyme. In a case-control study we investigated whether this COMT polymorphism is associated with endometriosis. METHODS Polymerase chain reaction was performed to analyze the COMT genotype among women with surgically and histologically confirmed endometriosis (study group; n = 91) and in women without evidence of endometriosis confirmed by laparoscopy or laparotomy (control group; n = 92). RESULTS Allele frequencies for the low-activity allele (COMT-L) among women with endometriosis and controls were 0.50 and 0.50, respectively (p = 0.999; odds ratio = 1.0, 95% CI: 0.66-1.51). CONCLUSIONS Our results suggest that the valine to methionine polymorphism in exon 4 of the COMT gene is not associated with the risk of endometriosis compared to a surgical control population.

Abstract
Estradiol is a pleiotropic hormone, involved in the etiology of a wide variety of diseases. Over the last decade individual genetic variability of the estradiol metabolism has been described as a significant contributor to disease susceptibility with variations depending on ethnic background. Among others, genetic variations of genes encoding cytochrome P450 (CYP) enzymes play an important role in this regard. Mutant alleles of the CYP 1A1 gene are major modulators of lung cancer risk among smokers, mediate gender differences in lung cancer susceptibility, and have been associated with an elevated risk for developing breast, prostate, colorectal, and oral squamous cell cancer. Variants of the CYP 1B1 gene modulate the risk for developing prostate, ovarian, lung, and breast cancer. Also, mutations in the CYP 1B1 gene are the major genetic determinant of congenital glaucoma. Mutant CYP 17 alleles are associated with serum and plasma levels of steroid hormones, use of hormone replacement therapy, and the development of endometrial, prostate, and breast cancer. Available data indicate that the protective effect against breast cancer of a later age at menarche is limited to wild-type CYP 17 allele carriers. Among women with the polycystic ovary syndrome, carriage of mutant CYP 17 alleles is sufficient to aggravate the clinical presentation of the disease. Molecular variants of the CYP 19 gene are associated with an increased risk for developing breast cancer, advanced breast cancer stages, and tumor aromatase production. Carriage of a mutant catechol-O-methyltransferase allele is associated with breast cancer, neurologic disorders such as Parkinson's disease, and modulates behavior among patients with schizophrenia, alcoholics and the general population. In summary, the available evidence points to genes that encode estrogen-metabolizing enzymes as strong hereditary determinants of the susceptibility to benign as well as malignant conditions.
