Glycodelin is internalized by peripheral monocytes. J Reprod Immunol 2020; 138:103102. [PMID: 32120159 DOI: 10.1016/j.jri.2020.103102] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 01/31/2020] [Accepted: 02/13/2020] [Indexed: 01/21/2023]
Abstract
Glycodelin is produced by the endometrial cells during the luteal phase and first trimester of pregnancy and plays a role in the regulation of the endometrial immunology. However, the molecular connection between glycodelin and the maternal immune system is not clear. To better understand the possible physiological interaction between the endometrium and the maternal immune system, we investigated (1) whether glycodelin binds to mainly peripheral monocytes, and in case (2) whether the binding to the membrane only depends on the protein backbone or a carbohydrate structure is needed, and in case (3) whether glycodelin is internalized after binding to the membrane. We demonstrated that glycodelin - with or without the carbohydrate structure - was preferentially bound and internalized to peripheral monocytes. Surprisingly, we found signals in the nucleus of the monocytes indicating a potential regulating effect of glycodelin may be exerted through the nucleus. However, further studies should be performed to confirm this finding.

Differential gene expression during placentation in pregnancies conceived with different fertility treatments compared with spontaneous pregnancies. Fertil Steril 2019; 111:535-546. [PMID: 30611556 DOI: 10.1016/j.fertnstert.2018.11.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Revised: 11/03/2018] [Accepted: 11/05/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To identify differences in the transcriptomic profiles during placentation from pregnancies conceived spontaneously vs. those with infertility using non-in vitro fertilization (IVF) fertility treatment (NIFT) or IVF. DESIGN Cohort study. SETTING Academic medical center. PATIENT(S) Women undergoing chorionic villus sampling at gestational age 11-13 weeks (n = 141), with pregnancies that were conceived spontaneously (n = 74), with NIFT (n = 33), or with IVF (n = 34), resulting in the delivery of viable offspring. INTERVENTION(S) Collection of chorionic villus samples from women who conceived spontaneously, with NIFT, or with IVF for gene expression analysis using RNA sequencing. MAIN OUTCOME MEASURE(S) Baseline maternal, paternal, and fetal demographics, maternal medical conditions, pregnancy complications, and outcomes. Differential gene expression of first-trimester placenta. RESULT(S) There were few differences in the transcriptome of first-trimester placenta from NIFT, IVF, and spontaneous pregnancies. There was one protein-coding differentially expressed gene (DEG) between the spontaneous and infertility groups, CACNA1I, one protein-coding DEG between the spontaneous and IVF groups, CACNA1I, and five protein-coding DEGs between the NIFT and IVF groups, SLC18A2, CCL21, FXYD2, PAEP, and DNER. CONCLUSION(S) This is the first and largest study looking at transcriptomic profiles of first-trimester placenta demonstrating similar transcriptomic profiles in pregnancies conceived using NIFT or IVF and spontaneous conceptions. Gene expression differences found to be highest in the NIFT group suggest that the underlying infertility, in addition to treatment-related factors, may contribute to the observed gene expression profiles.

Abstract
BACKGROUND The aim was to investigate whether first trimester glycodelin and angiopoietin-2 can predict small-for-gestational age (SGA) at delivery, individually or in combination. METHODS In this case-control study we measured glycodelin and angiopoietin-2 on serum from 170 singleton pregnant women delivering SGA neonates and 985 singleton pregnant women delivering normal-weighted neonates. All values were converted to multiples of the medians (MoM). RESULTS Pregnant women delivering SGA neonates had lower first trimester glycodelin and angiopoietin-2 MoM values [median (interquartile range)] compared with pregnant women delivering normal-weighted neonates for glycodelin: 0.86 (0.58-1.24) vs. 1.03 (0.74-1.45), p<0.001, and for angiopoietin-2: 0.89 (0.69-1.19) vs. 1.01 (0.78-1.31), p<0.001. The prediction performances of the biomarkers showed that the areas under the curve (AUC) were 0.59 (glycodelin), 0.58 (angiopoietin-2), and 0.60 (glycodelin and angiopoietin-2). CONCLUSIONS We demonstrated that first trimester glycodelin and angiopoietin-2 were associated with SGA, but they were, individually and in combination, poor predictors of SGA at delivery. The AUCs were low which indicate low detection rates and high false positive rates.

Abstract
Glycodelin A (GdA) is a lipocalin with an immunomodulatory role. Low expression of GdA has been implicated in the progression of autoimmune disease. Therefore, strategies targeting GdA may constitute an important target for the design of drugs for autoimmune disease including systemic lupus erythematosus (SLE). This opinion article will focus on current understanding of the role of GdA in the physiological and pathological functions associated with SLE. It is the intention of the article to provide insights that may assist in the development of GdA-based approaches for the treatment of SLE.

Abstract
Invasive trophoblastic mole is an extremely rare condition. Its early recognition is essential since it can transform into an invasive type of tumour. Immunohistochemistry was performed with monoclonal antibodies against inhibin-alpha, -betaA and -betaB, Ki67, p53 and glycodelin A in a rare case of accidentally diagnosed invasive trophoblastic mole. There was labelling of the inhibin/activin subunits, Ki67 and p53, while glycodelin A showed minimal immunopositivity. Therefore, since the pathological diagnosis of an invasive mole is difficult, the immunohistochemical detection of inhibin/activin subunits, Ki67, p53 and glycodelin A might be additional useful tumour markers.

Abstract
Glycodelin (Gd) is a major reproductive glycoprotein and a mediator for immunomodulatory effects directed to cellular, humoral, and innate immunity. Human pregnancy depends on a diversity of physiological processes including modulation of the maternal immunosystem. We evaluated the expression of Gd protein and mRNA in first trimester decidual tissue of normal pregnancies and spontaneous abortion and hydatidiform moles. Furthermore, in vitro experiments on endometrial cancer cells to analyze the effect of human chorionic gonadotropin (hCG) on Gd regulation were performed. In decidual tissue of abortion patients, Gd expression was significantly decreased compared with normal gestation, which was confirmed by in situ hybridization. In mole pregnancy, an upregulation of Gd in the first 8 weeks of pregnancy was present. Gd is a main product of decidual tissue in the first trimester of human pregnancy. Reduced Gd expression in abortive pregnancy could lead to an increased activation of the maternal immunosystem, thus causing rejection of the developing fetus. Moreover, Gd expression in endometrial cancer cells in vitro could be stimulated by addition of hCG. Therefore, we speculate that hCG could be one of the factors regulating Gd expression because hCG is downregulated in women with abortion and upregulated in mole pregnancy. In addition, we found a positive feedback loop in Gd and hCG expression in human pregnancy.

Glycodelin A is expressed differentially in normal human endometrial tissue throughout the menstrual cycle as assessed by immunohistochemistry and in situ hybridization. Fertil Steril 2006; 86:1488-97. [PMID: 17070198 DOI: 10.1016/j.fertnstert.2006.03.062] [Citation(s) in RCA: 18] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2005] [Revised: 03/31/2006] [Accepted: 03/31/2006] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To [1] evaluate glycodelin A immunolabeling in normal endometrium with specific monoclonal (mAb) and polyclonal peptide (pAb) antibodies, [2] to assess glycodelin messenger RNA (mRNA) by in situ hybridization, and [3] to conduct deglycosylation experiments to evaluate the recognized epitope of the mAb vs. pAb. DESIGN Retrospective immunohistochemical analysis. SETTING University institute and hospital in Germany. PATIENT(S) Normal human endometrial tissue from the proliferative (PP), early secretory, and late secretory phases were obtained from patients undergoing surgery for benign diseases. INTERVENTION(S) Generation of a pAb in rabbit, immunohistochemistry, and in situ hybridization. MAIN OUTCOME MEASURE(S) Semiquantitative and computerized analysis. RESULT(S) A statistically significant increase of the glycodelin A immunolabeling in the late secretory phase compared with PP was demonstrated by using the mAb. Polyclonal-peptide antibody immunolabeling also showed a rise between the PP and late secretory phases, but without statistical significance. In situ hybridization demonstrated a statistically significantly higher mRNA content during the early secretory phase compared with during PP. CONCLUSION(S) Glycodelin was demonstrated in normal endometrium at the protein and mRNA levels. The mAb may be more useful in assessing glycodelin expression in endometrium, because it probably can bind to glycodelin A-unique glycan structures, in contrast to the peptide pAb. This is of major interest because it may reveal possible structural and functional relationships in different parts of this molecule and elucidate possible functions of this glycoprotein in human endometrial tissue.
