Abstract
Estradiol (E2) is a major hormone-controlling folliculogenesis whose dysfunction may participate in polycystic ovary syndrome (PCOS) infertility. To determine whether both the concentration and action of E2 could be impaired in non-hyperandrogenic overweight PCOS women, we isolated granulosa cells (GCs) and follicular fluid (FF) from follicles of women undergoing ovarian stimulation (27 with PCOS, and 54 without PCOS). An analysis of the transcript abundance of 16 genes in GCs showed that androgen and progesterone receptor expressions were significantly increased in GCs of PCOS (by 2.7-fold and 1.5-fold, respectively), while those of the steroidogenic enzymes CYP11A1 and HSD3B2 were down-regulated (by 56% and 38%, respectively). Remarkably, treatment of GC cultures with E2 revealed its ineffectiveness in regulating the expression of several key endocrine genes (e.g., GREB1 or BCL2) in PCOS. Additionally, a comparison of the steroid concentrations (measured by GC/MS) in GCs with those in FF of matched follicles demonstrated that the significant decline in the E2 concentration (by 23%) in PCOS FF was not the result of the E2 biosynthesis reduction. Overall, our study provides novel hallmarks of PCOS by highlighting the ineffective E2 signaling in GCs as well as the dysregulation in the expression of genes involved in follicular growth, which may contribute to aberrant folliculogenesis in non-hyperandrogenic women with PCOS.

Abstract
Granulosa cell tumor (GCT) is a form of ovarian tumor characterized by its tendency to recur years after surgical ablation. Little is known on the mechanisms involved in GCT development and progression. GCTs can produce estradiol (E2), but whether this hormone could play a role in this cancer through its nuclear receptors, i.e., ERα and ERβ, remains unknown. Here, we addressed this issue by cell-based and molecular studies on human GCTs and GCT cell lines. Importantly, we observed that E2 significantly increased the growth of GCT cells by promoting cell survival. The use of selective agonists of each type of receptor, together with Esr1 (ERα) or Esr2 (ERβ)-deleted GCT cells revealed that E2 mediated its effects through ERα-dependent genomic mechanisms and ERβ/ERα-dependent extra-nuclear mechanisms. Notably, the expression of Greb1, a prototypical ER target gene, was dose-dependently up-regulated by E2 specifically through ERα in GCT cells. Accordingly, using GCTs from patients, we found that GREB1 mRNA abundance was positively correlated to intra-tumoral E2 concentrations. Tissue microarrays analyses showed that there were various combinations of ER expression in primary and recurrent GCTs, and that ERα expression persisted only in combination with ERβ in ~40% of recurrent tumors. Altogether, this study demonstrates that E2 can promote the progression of GCTs, with a clear dependence on ERα. In addition to demonstrating that GCTs can be classified as a hormone-related cancer, our results also highlight that the nature of ER forms present in recurrent GCTs could underlie the variable efficiency of endocrine therapies.

Abstract
Anti-Müllerian hormone (AMH), also called Müllerian inhibiting substance, was shown to be synthesized by the ovary in the 1980s. This article reviews the main findings of the past 20 years on the regulation of the expression of AMH and its specific receptor AMHR2 by granulosa cells, the mechanism of action of AMH, the different roles it plays in the reproductive organs, its clinical utility, and its involvement in the principal pathological conditions affecting women. The findings in respect of regulation tell us that AMH and AMHR2 expression is mainly regulated by bone morphogenetic proteins, gonadotropins, and estrogens. It has now been established that AMH regulates the different steps of folliculogenesis and that it has neuroendocrine effects. On the other hand, the importance of serum AMH as a reliable marker of ovarian reserve and as a useful tool in the prediction of the polycystic ovary syndrome (PCOS) and primary ovarian failure has also been acknowledged. Last but not least, a large body of evidence points to the involvement of AMH in the pathogenesis of PCOS.

Abstract
Abstract
Background
Korian® group is specialized in care and support for fragile people. Its data warehouse manages 304 French nursing homes (NH). The transmissions' table (TT), daily-fed by caregivers, contains key data about residents' care and health. Following GDPR rules, we could still build residents' life trajectories and detail all the residents' health events using indexes. In the past, we designed syndromes such as falls, flu, and last year, COVID with the standard query language. Now we want to combine ‘hard' data such as sociodemographic profiles and COVID vaccines with ‘soft' textual data such as COVID and emergency calls syndromes to get a better residents vaccine monitoring.
Methods
First, we selected all residents with at least one transmission, from December 21, to January 11, just before the COVID vaccination start, from 34 NH chosen for their variety of size and geographic location. We followed them for eleven weeks starting January 4, 2021. We selected the residents' age, sex, autonomy level, comorbidities and risks and then, vaccinations (0, 1 or 2), syndromes, hospitalizations and deaths date events. We searched for sample data inconsistencies by filtering COVID textual information in the TT and comparing it with the vaccination table. We described the sample according to the NH size, and then according to the number of vaccinations. Finally, we assessed COVID syndromes, falls, hospitalizations, emergency calls and deaths according to vaccinations followed by Poisson and logistic regressions.
Results
We built a 2,051 residents cohort with 1,401 vaccinated at least once and 650 not yet vaccinated. Data corrections then added 60 vaccinations. Residents in big structures were more masculine (72,9% vs 75,1%), more vaccinated (77,2% vs 67,2%), younger (86,7 vs 87,5), more autonomous (2,6, vs 2,4). Vaccination rates were also greater among those with comorbidities and risks.
Conclusions
By focusing on the TT resident's health events, we improved health modelization
Key messages
By using all the COVID information available in the database, we were able to show both, the beneficial effect of vaccination and the nefarious effect of COVID in a same model with machine learning. Aggregating hard categorical and numerical data with soft textual information about the resident’s health events, dates included, gives a precise and complete resident’s profile and health trajectory.

Abstract
PURPOSE A protective effect of anti-Müllerian hormone (AMH) on follicle atresia was recently demonstrated using long-term treatments, but this effect has never been supported by mechanistic studies. This work aimed to gain an insight into the mechanism of action of AMH on follicle atresia and on how this could account for the increased follicle pool observed in women with polycystic ovary syndrome (PCOS). METHODS In vivo and in vitro experiments were performed to study the effects of AMH on follicle atresia and on the proliferation and apoptosis of granulosa cells (GCs). RNA-sequencing was carried out to identify new AMH target genes in GCs. The expression of some of these genes in GCs from control and PCOS women was compared using microfluidic real time quantitative RT-PCR. RESULTS A short-term AMH treatment prevented follicle atresia in prepubertal mice. Consistent with this result, AMH inhibited apoptosis and promoted proliferation of different models of GCs. Moreover, integrative biology analyses of 965 AMH target genes identified in 1 of these GC models, confirmed that AMH had initiated a gene expression program favoring cell survival and proliferation. Finally, on 43 genes selected among the most up- and down-regulated AMH targets, 8 were up-regulated in GCs isolated from PCOS women, of which 5 are involved in cell survival. MAIN CONCLUSIONS Our results provide for the first time cellular and molecular evidence that AMH protects follicles from atresia by controlling GC survival and suggest that AMH could participate in the increased follicle pool of PCOS patients.

Abstract
Type-I x-ray bursts can reveal the properties of an accreting neutron star system when compared with astrophysics model calculations. However, model results are sensitive to a handful of uncertain nuclear reaction rates, such as ^{22}Mg(α,p). We report the first direct measurement of ^{22}Mg(α,p), performed with the Active Target Time Projection Chamber. The corresponding astrophysical reaction rate is orders of magnitude larger than determined from a previous indirect measurement in a broad temperature range. Our new measurement suggests a less-compact neutron star in the source GS1826-24.

Abstract
BACKGROUND Obesity is a risk factor for stress-related mental disorders such as post-traumatic stress disorder. The underlying mechanism through which obesity affects mental health remains poorly understood but dysregulation of the ghrelin system may be involved. Stress increases plasma ghrelin levels, which stimulates food intake as a potential stress-coping mechanism. However, diet-induced obesity induces ghrelin resistance which in turn may have deleterious effects on stress-coping. In our study, we explored whether disruption of ghrelin receptor function though high-fat diet or genetic ablation affects fear processing, anxiety-like behavior and saccharin preference in mice. METHODS Adult male C57BL6/J mice were placed on a standard diet or high-fat diet for a total period of 8 weeks. We first established that high-fat diet exposure for 4 weeks elicits ghrelin resistance, evidenced by a blunted hyperphagic response following administration of a ghrelin receptor agonist. We then carried out an experiment in which we subjected mice to auditory fear conditioning after 4 weeks of diet exposure and evaluated effects on fear extinction, anxiety-like behavior and saccharin preference. To explore whether fear conditioning as such may influence the effect of diet exposure, we also subjected mice to auditory fear conditioning prior to diet onset and 4 weeks later we investigated auditory fear extinction, anxiety-like behavior and saccharin preference. In a final experiment, we further assessed lack of ghrelin receptor function by investigating auditory fear processing, anxiety-like behavior and saccharin preference in ghrelin receptor knockout mice and their wild-type littermates. RESULTS High-fat diet exposure had no significant effect on auditory fear conditioning and its subsequent extinction or on anxiety-like behavior but significantly lowered saccharin preference. Similarly, ghrelin receptor knockout mice did not differ significantly from their wild-type littermates for auditory fear processing or anxiety-like behavior but showed significantly lower saccharin preference compared to wild-type littermates. CONCLUSION Taken together, our data suggest that disruption of ghrelin receptor function per se does not affect fear or anxiety-like behavior but may decrease saccharin preference in mice.

Abstract
CONTEXT Anti-Müllerian hormone (AMH) and AMH type II receptor (AMHR2) are overexpressed in granulosa cells (GCs) from women with polycystic ovary syndrome (PCOS), the most common cause of female infertility. OBJECTIVE The aim of the study was to compare the regulation of the AMH/AMHR2 system by 5α-dihydrotestosterone (5α-DHT) and estradiol (E2) in GCs from control subjects and women with PCOS. DESIGN, SETTING, PATIENTS Experiments were performed on follicular fluids (FF) and GCs from women undergoing in vitro fertilization. MAIN OUTCOME MEASURES FF steroid levels were measured by mass spectrometry, and messenger RNA (mRNA) accumulation was quantified by reverse transcription real-time polymerase chain reaction. RESULTS Total testosterone (T), free T, and 5α-DHT FF levels were significantly higher (P < 0.001) in women with PCOS than in controls. However, E2 and sex hormone-binding globulin concentrations were comparable between the two groups. In GCs from control women, the AMH and AMHR2 expression were not affected by 5α-DHT treatment, whereas AMH mRNA levels were upregulated by 5α-DHT in GCs from patients with PCOS (2.3-fold, P < 0.01) overexpressing the androgen receptor (1.4-fold, P < 0.05). E2 downregulated the AMH and AMHR2 expression in GCs from control women (1.4-fold, P < 0.001 and 1.8-fold, P < 0.01, respectively) but had no effect on these genes in GCs from women with PCOS. This differential effect of E2 was associated with a higher estrogen receptor 1 expression in GCs from women with PCOS (1.9-fold, P < 0.05). CONCLUSIONS In GCs from women with PCOS, the regulation of AMH and AMHR2 expression is altered in a way that promotes the overexpression of the AMH/AMHR2 system, and could contribute to the follicular arrest observed in these patients.

Abstract
Secretion of 17-β-estradiol (E2) by human granulosa cells can be disrupted by various environmental toxicants. In the current study, we investigated whether carbon black nanoparticles (CB NPs) affect the steroidogenic activity of cultured human granulosa cells. The human granulosa cell line KGN and granulosa cells from patients undergoing in vitro fertilization were treated with increasing concentrations of CB NPs (1 to 100 µg/mL) together or not with follicle-stimulating hormone (FSH). We observed that CB NPs are internalized in KGN cells without affecting cell viability. CB NPs could be localized in the cytoplasm, within mitochondria and in association with the outer face of the endoplasmic reticulum membrane. In both cell types, CB NPs reduced in a dose-dependent manner the activity of aromatase enzyme, as reflected by a decrease in E2 secretion. A significant decrease was observed in response to CB NPs concentrations from 25 and 50 µg/mL in KGN cell line and primary cultures, respectively. Furthermore, CB NPs decreased aromatase protein levels in both cells and reduced aromatase transcript levels in KGN cells. CB NPs rapidly activated extracellular signal-regulated kinase 1 and 2 in KGN cells and pharmacological inhibition of this signaling pathway using PD 98059 significantly attenuated the inhibitory effects of CB NPs on CYP19A1 gene expression and aromatase activity. CB NPs also inhibited the stimulatory effect of FSH on aromatase expression and activity. Altogether, our study on cultured ovarian granulosa cells reveals that CB NPs decrease estrogens production and highlights possible detrimental effect of these common NPs on female reproductive health.

Abstract
CONTEXT Anti-Müllerian hormone (AMH) is an important clinical marker for diagnosing and assessing the reproductive status and/or disorders in men and women. Most studies have not distinguished between levels of inactive AMH precursor and the cleaved noncovalent complex that binds the AMH type II receptor (AMHRII) and initiates signaling. OBJECTIVE The objective of the study was to measure the levels of AMH cleavage and bioactivity in human body fluids. DESIGN, SETTING, AND PATIENTS AMH cleavage levels and bioactivity were measured in the serum of six boys and in the follicular fluid and serum of nine control women and 13 women with the polycystic ovary syndrome (PCOS). MAIN OUTCOME MEASURES AMH cleavage levels were measured by capturing AMH with an anti-AMH antibody, followed by Western blotting. The bioactivity of cleaved AMH was assessed with an ELISA that measures the levels of AMH capable of binding AMHRII. RESULTS PCOS women have an elevated level of AMH cleavage in their follicular fluid (24% vs 8% in control women), and most of the cleaved AMH can bind AMHRII. Higher levels of cleavage are observed in female (60%) and male (79%) serum, but very little of the cleaved AMH can bind AMHRII. CONCLUSIONS These results support an autocrine role for AMH in the pathophysiology of PCOS in the follicle. In addition, they indicate that AMH undergoes interactions or structural changes after cleavage that prevent receptor binding, meaning, unexpectedly, that the level of cleaved AMH in biological fluids does not always reflect the level of bioactive AMH.

Abstract
The prognosis for locally advanced esophageal cancer is poor despite the use of trimodality therapy. In this phase II study, we report the feasibility, tolerability and efficacy of adjuvant sunitinib. Included were patients with stage IIa, IIB or III cancer of the thoracic esophagus or gastroesophageal junction. Neoadjuvant therapy involved Irinotecan (65 mg/m2 ) + Cisplatin (30 mg/m2 ) on weeks 1 and 2, 4 and 5, 7 and 8 with concurrent radiation (50Gy/25 fractions) on weeks 4-8. Sunitinib was commenced 4-13 weeks after surgery and continued for one year. Sixty-one patients were included in the final analysis, 36 patients commenced adjuvant sunitinib. Fourteen patients discontinued sunitinib due to disease recurrence (39%) within the 12-month period, 12 (33%) discontinued due to toxicity, and 3 (8%) requested cessation of therapy. In the overall population, median survival was 26 months with a 2 and 3-year survival rate of 52% and 35%, respectively. The median survival for the 36 patients treated with sunitinib was 35 months and 2-year survival probability of 68%. In a historical control, a prior phase II study with the same trimodality therapy (n = 43), median survival was 36 months, with a 2-year survival of 67%. Initiation of adjuvant sunitinib is feasible, but poorly tolerated, with no signal of additional benefit over trimodality therapy for locally advanced esophageal cancer.

Abstract
Patient premedication with carbidopa seems to improve the accuracy of 6-18F-fluoro-3,4-dihydroxy-l-phenylalanine (18F-FDOPA) PET for insulinoma diagnosis. However, the risk of PET false-negative results in the presence of carbidopa is a concern. Consequently, we aimed to evaluate the effect of carbidopa on 18F-FDOPA uptake in insulinoma β-cells and an insulinoma xenograft model in mice. METHODS 18F-FDOPA in vitro accumulation was assessed in the murine β-cell line RIN-m5F. In vivo small-animal PET experiments were performed on tumor-bearing nude mice after subcutaneous injection of RIN-m5F cells. Experiments were conducted with and without carbidopa pretreatment. RESULTS Incubation of RIN-m5F cells with 80 μM carbidopa did not significantly affect the cellular accumulation of 18F-FDOPA. Tumor xenografts were clearly detectable by small-animal PET in all cases. Insulinoma xenografts in carbidopa-treated mice showed significantly higher 18F-FDOPA uptake than those in nontreated mice. Regardless of carbidopa premedication, the xenografts were characterized by an early increase in 18F-FDOPA uptake and then a progressive reduction over time. CONCLUSION Carbidopa did not influence in vitro 18F-FDOPA accumulation in RIN-m5F cells but improved insulinoma imaging in vivo. Our findings increase current knowledge about the 18F-FDOPA uptake profile of RIN-m5F cells and a related xenograft model. To our knowledge, the present work represents the first preclinical research specifically focused on insulinomas, with potential translational implications.

Abstract
The adsorption of polymeric sulphonated naphthalene formaldehyde (SNF) and sulphonated melamine formaldehyde (SMF) on to titanium dioxide and calcium carbonate has been measured in aqueous media. The magnitude of these adsorptions is strongly dependent on electrostatic interaction irrespective of the pH value. This result has been established by studying the adsorption of the polyelectrolytes from solutions of different composition. The calcium ion plays a prominent role in the process of adsorption, especially at high pH where electrical interactions do not favour the reaction. The polymeric nature of the fluidizing agents is demonstrated by an increase in adsorption with molecular weight and by adsorption/desorption experiments where the reaction has been shown to be irreversible. The amount adsorbed at maximum coverage does not depend on the nature of the mineral, but mainly on electrical interactions between the monomer units.

Abstract
CONTEXT Anti-Müllerian hormone (AMH) is produced by the granulosa cells (GCs) of growing follicles and inhibits follicular development. OBJECTIVE This study aimed to investigate the regulation of the AMH-specific type 2 receptor (AMHR2) gene expression in GCs by bone morphogenetic protein (BMP)15, BMP4 and growth differentiation factor (GDF)9. DESIGN, SETTING, AND PATIENTS Their effects on AMHR2 and AMH mRNAs were studied in luteinized human GCs and in ovine GCs (oGCs) from small antral follicles. The effects of BMPs on human AMHR2 and AMH promoter reporter activities were analyzed in transfected oGCs. The in vivo effect of BMP15 on GCs AMHR2 and AMH expression was investigated by using Lacaune and Rasa Aragonesa hyperprolific ewes carrying loss-of-function mutations in BMP15. MAIN OUTCOME MEASURES mRNAs were quantified by real-time RT-PCR. Promoter reporter constructs activities were quantified by the measurement of their luciferase activity. RESULTS BMP15 and BMP4 enhanced AMHR2 and AMH expression in human GCs and in oGCs, whereas GDF9 had no effect. In oGCs, GDF9 increased BMP15 effect on AMH expression. Consistent with these results, BMP15 and BMP4, but not GDF9, enhanced AMHR2 promoter activity in oGCs, whereas GDF9 increased BMP15 effect on AMH promoter activity. Moreover, oGCs from both BMP15 mutant ewes had reduced AMHR2 mRNA levels but unchanged AMH expression compared with wild-type ewes. CONCLUSIONS Altogether, these results suggest that the mechanisms of action of BMP15 on AMHR2 and AMH expression are different, and that by stimulating AMHR2 and AMH expression in GCs BMP15 enhances AMH inhibitory actions in GCs.

Abstract
The growing demand for suitable lungs for transplantation drives the quest for alternative strategies to expand the donor pool. The aim of this study is to evaluate the outcomes of lung transplantation (LTx) with donation after circulatory determination of death (DCDD) and the impact of selective ex vivo lung perfusion (EVLP). From 2007 to 2013, 673 LTx were performed, with 62 (9.2%) of them using DCDDs (seven bridged cases). Cases bridged with mechanical ventilation/extracorporeal life support were excluded. From 55 DCDDs, 28 (51%) underwent EVLP. Outcomes for LTx using DCDDs and donation after neurological determination of death (DNDD) donors were similar, with 1 and 5-year survivals of 85% and 54% versus 86% and 62%, respectively (p = 0.43). Although comparison of survival curves between DCDD + EVLP versus DCDD-no EVLP showed no significant difference, DCDD + EVLP cases presented shorter hospital stay (median 18 vs. 23 days, p = 0.047) and a trend toward shorter length of mechanical ventilation (2 vs. 3 days, p = 0.059). DCDDs represent a valuable source of lungs for transplantation, providing similar results to DNDDs. EVLP seems an important technique in the armamentarium to safely increase lung utilization from DCDDs; however, further studies are necessary to better define the role of EVLP in this context.

Abstract
In the ovary, anti-Müllerian hormone (AMH) is produced by the granulosa cells of growing follicles and can modulate the recruitment of primordial follicles and the FSH-dependent development of follicles. However, the regulation of its production remains poorly understood. Recently, a stimulating effect of the bone morphogenetic proteins (BMPs) on AMH production by granulosa cells has been shown in vitro, but the molecular mechanisms implicated in this regulation and its physiological importance in ovarian function have not yet been established. In the hyperprolific Booroola ewes carrying the FecB(B) partial loss-of-function mutation in the fecundity gene encoding the FecB/BMP receptor, type 1B, the granulosa cells of antral follicles expressed and secreted low AMH amounts, resulting in low AMH concentrations in blood, despite high numbers of AMH-secreting follicles in ovaries. The presence of the FecB(B) mutation impaired the granulosa cell response to the stimulating action of BMP4 on AMH production, indicating a crucial role of the BMP receptor, type 1B in AMH regulation. In ovine granulosa cells, BMP4 enhanced the transcriptional activity of the human AMH promoter, and this action depended on the presence of SMAD1, acting on a promoter sequence located between -423 and -202 bp upstream of the AMH transcription start site. SMAD1 and SF1 acted in concert to mediate BMP4 action on the AMH promoter. Among the 2 SF1 binding sites present on the AMH promoter, the most proximal site, located at -92 bp upstream of the AMH transcription start site, was found to be critical for ensuring the response of the AMH promoter to BMP4. In conclusion, AMH could mediate the actions of BMPs in regulating follicular development and contributing to the determination of ovulation numbers. A molecular model of regulation of the AMH promoter transactivation by BMP signaling is proposed.

Abstract
Evaluate the use of multiplex real-time PCR for diagnosing respiratory infections. 857/966 samples from 914 children were positive for one or multiple viruses. Respiratory syncytial virus and rhinovirus were the most prevalent. Co-infections were associated with severe respiratory symptoms. The spread of respiratory viruses returned to the one it was before the flu outbreak.
Background The use of a multiplex molecular technique to identify the etiological pathogen of respiratory viral infections might be a support as clinical signs are not characteristic. Objectives The aim of the study was to evaluate a multiplex molecular real-time assay for the routine diagnosis of respiratory viruses, to analyze the symptoms associated with the pathogens detected and to determine the spread of virus during the period. Study design Respiratory samples were collected from children presenting with respiratory symptoms and attending the emergency unit during the 2010–2011 winter seasons. Samples were tested with the multiplex RespiFinder® 15 assay (PathoFinder™) which potentially detects 15 viruses. Results 857 (88.7%) of the 966 samples collected from 914 children were positive for one (683 samples) or multiple viruses (174 samples). The most prevalent were the respiratory syncytial virus (39.5%) and the rhinovirus (24.4%). Influenza viruses were detected in 139 (14.4%) samples. Adenovirus was detected in 93 (9.6%) samples, coronaviruses in 88 (9.1%), metapneumovirus in 51 (5.3%) and parainfluenzae in 47 (4.9%). Rhinovirus (40%) was the most prevalent pathogen in upper respiratory tract infections while respiratory syncytial virus (49.9%) was the most prevalent in lower respiratory tract infections. Co-infections were associated with severe respiratory symptoms. Conclusion The multiplex assay detected clinically important viruses in a single genomic test and thus will be useful for detecting several viruses causing respiratory tract disorders.

Abstract
STUDY QUESTION Are anti-Müllerian hormone (AMH) and AMH type II receptor (AMHR-II) mRNAs similarly regulated by gonadotrophins in lutein granulosa cells (GCs) from control, normo-ovulatory and oligo/anovulatory women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER AMH mRNA expression was induced by LH only in lutein GC of oligo/anovulatory PCOS women; down-regulation of AMHR-II, induced by LH in control and normo-ovulatory PCOS women, was absent in oligo/anovulatory women. WHAT IS KNOWN ALREADY It was suggested that AMH could be responsible for the blockade of follicles at the small antral stage in PCOS women. In keeping with this hypothesis, both AMH and AMHR-II are overexpressed in lutein GCs from oligo/anovulatory PCOS women. STUDY DESIGN, SIZE, DURATION Women undergoing IVF were included in this prospective study, either in the control group (30 women) or in the PCOS group (21 normo-ovulatory and 19 oligo/anovulatory patients) between January 2010 and July 2012. PARTICIPANTS/MATERIALS, SETTING, METHODS Human lutein GCs were isolated from follicular fluid during IVF protocols. Twenty-four hours after seeding, lutein GCs from each woman were serum starved and cultured for 48 h ± FSH, LH or cAMP. Then AMH and AMHR-II mRNAs were quantified by quantitative RT-PCR and AMH protein concentration was measured in the culture medium by ELISA. Experimental results were analyzed, within each group of women, by the non-parametric Wilcoxon test for paired comparisons between cells cultured in control medium and FSH, LH or cAMP treated cells. Clinical comparisons between the three groups of women were performed on log values using the ANOVA test with Bonferroni correction. MAIN RESULTS AND THE ROLE OF CHANCE FSH up-regulated both AMH expression and secretion by lutein GCs from the three groups of women (P < 0.05). LH had no effect on AMH mRNAs levels in lutein GCs from controls and normo-ovulatory PCOS women, but increased AMH expression in oligo/anovulatory PCOS women (P < 0.05). Interestingly, LH and cAMP treatments reduced AMHR-II expression by lutein GCs from controls and normo-ovulatory PCOS women (P < 0.05), but had no effect on AMHR-II mRNA levels in oligo/anovulatory PCOS women. LIMITATIONS, REASONS FOR CAUTION The lutein GCs are not the best model to study AMH and AMHR-II regulation by gonadotrophins. Indeed, AMH and AMHR-II are down-regulated in luteinized cells. Furthermore, these cells have been exposed to non-physiological levels of gonadotrophins and hCG. However, AMH and AMHR-II mRNAs are quantifiable by real-time RT-PCR, and the cells are still responsive to FSH and LH. The age of patients is significantly different between control and oligo/anovulatory PCOS women: this may be a bias in the interpretation of results but older women in the control group had a good ovarian reserve. WIDER IMPLICATIONS OF THE FINDINGS The overexpression of AMH and AMHR-II in oligo/anovulatory PCOS women could be due to increased LH levels and/or inhibition of its repressive action. The fact that this dysregulation is observed in oligo/anovulatory, but not in normo-ovulatory, PCOS women emphasizes the role of LH in the follicular arrest of PCOS women and suggests that this involves the AMH/AMHR-II system. STUDY FUNDING/COMPETING INTEREST(S) The Assistance-Publique Hôpitaux de Paris provided a Contrat d'Interface and the Agence de Biomédecine provided a grant to Nathalie di Clemente. Schering-Plough provided an FARO grant to Alice Pierre. The authors have nothing to disclose.

Abstract
BACKGROUND Anti-müllerian hormone (AMH) is a member of the TGF-β family, which limits follicle maturation. Recently serum AMH has been recognized as a useful diagnostic and prognostic tool in human reproductive endocrinology. OBJECTIVE The aim of this study was to investigate the regulation of human ovarian AMH by estradiol and FSH. METHODS AMH mRNA were quantified by real time RT-PCR in human granulosa cells (GC). AMH transcription was studied in KK1 GC cotransfected with estrogen receptors (ER)-β or ERα, and normal human AMH promoter-luciferase construct (hAMH-luc) or mutated AMH promoter reporter constructs. Binding sites for estradiol (estrogen response element half-site) and steroidogenic factor 1 were disrupted by targeted mutagenesis. The level of ER in GC was determined by quantitative RT-PCR and Western blotting. RESULTS In KK1 cells, estradiol up-regulated and inhibited hAMH-luc in the presence of ERα and ERβ respectively. Disruption of estrogen response element half-site and/or steroidogenic factor 1 binding sites did not modify ERβ-mediated effect of estradiol on hAMH-luc, whereas it affected that conveyed by ERα. The FSH enhancement of hAMH-luc was abolished by estradiol in cells overexpressing ERβ. When both ER were transfected, estradiol inhibited hAMH-luc or had no effect. Estradiol repressed AMH mRNAs in human GC, which express a little more ERα than ERβ mRNA. CONCLUSIONS Our results show that AMH expression can be differentially regulated by estradiol depending on the ER and suggest that its decrease in GC of growing follicles, which mainly express ERβ, and during controlled ovarian hyperstimulation is due to the effect of estradiol.
