Abstract
The purpose of this study was to investigate the effect of G-CSF on the endometrial receptivity of implantation failure mice. Sixty female mice were treated mifepristone to establish an implant failure model. The treatment groups received different doses of G-CSF. Endometrial tissue and serum were collected on day 5 after mating. The abundance of pinopodes on the endometrium was observed by scanning electron microscopy. The expressions of LPAR3, COX2, and HOXA10 were detected by RT-qPCR and Western blotting. Serum levels of E2, P, VEGF, LIF, TNF-α and IL-10 were measured by ELISA. The expressions of VEGF, CD34, CD57, TNF-α, and IL-10 were assessed by immunohistochemistry. Immunofluorescence analysis was performed to determine the number of CD57, Treg, and Th17 cells. G-CSF increased implantation and pregnancy rates of mifepristone-induced implantation failure mice, with the most significant effect seen at the intermediate dose. G-CSF increased the serum levels of E2 and P, the abundance of endometrial pinopodes, and the level of LIF in the endometrium. It also promoted the expression of VEGF, HOXA10, LPAR3, and COX2. Moreover, G-CSF reduced the level of CD57 cells and the ratio of Th17/Treg cells in endometrium. G-CSF reduced the inflammatory factor TNF-α, but IL-10 did not change significantly. G-CSF can enhance embryo implantation rate and pregnancy rate and improve endometrial receptivity by attenuating degeneration of pinopodes, upregulating estrogen and progesterone, facilitating angiogenesis, maintaining immune cell homeostasis, and reducing the production of inflammatory cytokines in implantation failure mouse.

[PMID: 38308732 DOI: 10.1007/s00404-023-07359-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 12/21/2023] [Indexed: 02/05/2024]
Abstract
PURPOSE Our study aimed to investigate the best time to manage hydrosalpinx to improve pregnancy outcomes during in vitro fertilization-embryo transfer (IVF-ET). METHODS Patients with hydrosalpinx who received IVF treatment were analyzed retrospectively. And two groups were included to compare the effects of different timing treatment of hydrosalpinx on IVF pregnancy outcomes, "Proximal Tubal Occlusion First Group" (Group Ligation-COH) and "Oocyte Retrieval First Group" (Group COH-Ligation). The main outcome measures included: ovarian response indexes, laboratory indexes and clinical pregnancy outcomes. Univariate and multivariate Logistic regression analysis was performed for outcome indicators, and the odds ratios (OR) and 95% confidence interval (CI) were used. RESULTS A total of 1490 patients were included (n = 976 Ligation-COH and n = 514 COH-Ligation). The Gn starting dose and MII rate in group Ligation-COH were significantly higher than those in group COH-Ligation (203.33 ± 58.20 vs. 203.33 ± 58.20, 81.58% vs. 80.28%, P < 0.05). The number of oocytes obtained and the number of available D3 embryos in group COH-Ligation were higher than those in group Ligation-COH (15.10 ± 7.58 vs. 13.45 ± 6.42, 10.92 ± 5.81 vs. 9.94 ± 5.15, P < 0.05). Although the number of ET cycles per IVF cycle in group COH-Ligation was higher than that in group Ligation-COH (1.88 ± 1.00 vs. 1.48 ± 0.70, P < 0.05), the biochemical pregnancy rate, clinical pregnancy rate, multiple pregnancy rate, live birth rate and cumulative live birth rate in group Ligation-COH were significantly higher than those in group COH-Ligation (60.83% vs. 46.27% for biochemical pregnancy, 55.69% vs. 38.5% for clinical pregnancy, 26.18% vs. 17.74% for multiple pregnancy, 47.08% vs. 25.26% for live birth, 69.47% vs. 47.47% for cumulative live birth, P < 0.05), and the miscarriage rate in group Ligation-COH was lower than that in group COH-Ligation (10.47% vs. 17.20 for early abortion, 4.49% vs. 15.86% for late abortion, P < 0.05). In logistic regression analysis, after adjustment for age and multiple factors, the above results were still statistically significant differences (P < 0.001). For elderly patients, the clinical pregnancy rate, multiple birth rate and live birth rate in group Ligation-COH were also higher than those in group COH-Ligation (P < 0.001). No significant differences were detected for patients with diminished ovarian reserve. CONCLUSIONS For the choice of ligation operation time, we recommend that patients choose tubal ligation first and then ovulation induction and oocyte retrieval treatment.

Abstract
LIF is crucial in regulating embryo implantation, while HOXA10 is a marker gene for uterine receptivity. However, the specific mechanism of LIF regulating HOXA10 during cow embryo implantation has not been fully understood. To address this knowledge gap, the experiment involved treating bovine endometrial epithelial cells (BEECs) with LIF to investigate the relationship between LIF, miRNA, and HOXA10. The experimental findings revealed that applying LIF resulted in a substantial increase in the proliferation of endometrial epithelial cells. Moreover, the expressions of PI3K, AKT, HOXA10, CDK4, cyclinD1, and cyclinE1 were significantly elevated. Conversely, the expression of p21Cipl was significantly reduced. In the group that received a combination of LIF and a STAT3 inhibitor, the expression of PI3K/AKT remained significantly increased, but there was no significant change in the expression of HOXA10. When miRNA-27a-3p was overexpressed, it resulted in a decrease in both the RNA and protein expression of HOXA10. Conversely, inhibiting miRNA-27a-3p increased the RNA and protein expression of HOXA10. In the presence of LIF treatment, the expression of miRNA-27a-3p was reduced, while the expression of HOXA10 was increased. However, when LIF and a STAT3 inhibitor were combined, there was no significant change in the expression of miRNA-27a-3p or HOXA10. Consequently, LIF facilitated cell proliferation by activating the PI3K/AKT pathway. LIF controlled the expression of miRNA-27a-3p and HOXA10 in endometrial epithelial cells through STAT3, with miRNA-27a-3p negatively regulating the expression of HOXA10.

Abstract
The causes of implantation failure remain a black box in reproductive medicine. The exact mechanism behind the regulation of endometrial receptivity is still unknown. Epigenetic modifications influence gene expression patterns and may alter the receptivity of human endometrium. Cervical secretions contain endometrial genetic material, which can be used as an indicator of the endometrial condition. This study evaluates the association between the cervical secretion gene methylation profile and pregnancy outcome in a frozen-thawed embryonic transfer (FET) cycle. Cervical secretions were collected from women who entered the FET cycle with a blastocyst transfer (36 pregnant and 36 non-pregnant women). The DNA methylation profiles of six candidate genes selected from the literature review were measured by quantitative methylation-specific PCR (qMSP). Bioinformatic analysis of six selected candidate genes showed significant differences in DNA methylation between receptive and pre-receptive endometrium. All candidate genes showed different degrees of correlation with the pregnancy outcomes in the logistic regression model. A machine learning approach showed that the combination of candidate genes' DNA methylation profiles could differentiate pregnant from non-pregnant samples with an accuracy as high as 86.67% and an AUC of 0.81. This study demonstrated the association between cervical secretion methylation profiles and pregnancy outcomes in an FET cycle and provides a basis for potential clinical application as a non-invasive method for implantation prediction.

Abstract
Endometriosis is a chronic inflammatory disease causing distressing symptoms and requiring a life-long management strategy. The objective of this review is to evaluate endometriosis-related pathways and identify novel therapies to treat it. We focused on the crucial role of inflammation and inflammatory molecules in order to define new perspectives for non-hormonal treatment of the disease by targeting inflammation, nuclear factor kappa B and cytokines, or reactive oxygen species, apoptotic and autophagic pathways, regulators of epithelial-mesenchymal transition, and angiogenesis and neuroangiogenesis. Novel non-steroidal therapies targeting these pathways for endometriosis were explored, but multiple challenges remain. While numerous agents have been investigated in preclinical trials, few have reached the clinical testing stage because of use of inappropriate animal models, with no proper study design or reporting of preclinical strategies. Targeting estrogens is still the best way to control endometriosis progression and inflammation.

Abstract
In vitro fertilization and embryo transfer (IVF-ET) is one of the effective methods to treat female infertility. Poor endometrial receptivity (ER) is an important factor leading to embryo implantation dysfunction, which can reduce pregnancy rate of IVF-ET. The mice model with embryo implantation dysfunction in vivo and attachment model of trophoblast (JAR) spheroids in vitro were constructed. The levels of lncRNA NEAT1, HOXA10, CTCF and markers of ER were detected. The cell proliferation was measured. The interaction between lncRNA NEAT1 and CTCF, HOXA10 promoter and CTCF were confirmed. LncRNA NEAT1 and HOXA10 levels in infertile patients and mice model with embryo implantation dysfunction were increased. In vitro experiments showed that down-regulation of lncRNA NEAT1 improved EECs proliferation and ER marker expressions. LncRNA NEAT1 could bind to CTCF, and CTCF could bind to HOXA10 promoter and down-regulate HOXA10 gene expression by regulating histone modification level. The lncRNA NEAT1/CTCF/HOXA10 signaling pathway regulated EECs proliferation and ER establishment in vitro and in vivo. Our study suggested that lncRNA NEAT1 could up-regulate HOXA10 promoter activity and its expression by combining with CTCF, thus improving EECs proliferation and ER establishment, and ultimately facilitating embryo implantation.

Abstract
OBJECTIVE To study whether the methylation status of cervical secretions can reflect the ability of the endometrium to allow embryo implantation. DESIGN Case-control study. SETTING In vitro fertilization centers. PATIENT(S) Women undergoing embryo transfer cycles, in which at least 1 good-quality embryo was transferred. INTERVENTION(S) Collection of cervical secretions during the procedure of embryo transfer. MAIN OUTCOME MEASURE(S) Methylation profiles of cervical secretions in relation to pregnancy outcomes. RESULT(S) Genome-wide methylation profiles differ between cervical secretions from pregnancy and nonpregnancy cycles. Clustering analysis on the basis of the top 2,000 differentially methylated probes of cervical secretions from 28 pregnancy and 29 nonpregnancy cycles correctly categorized 86.0% of the samples in terms of conceptional status, which was verified in selected genes by quantitative methylation-specific polymerase chain reaction and validated in another independent sample set. The combination of selected genes was estimated to predict pregnancy outcomes with a maximal area under the receiver operating characteristic curve of 0.83. CONCLUSION(S) The methylation profiles of cervical secretions were associated with pregnancy outcomes in embryo transfer cycles. Although not clinically useful at present, deoxyribonucleic acid methylation in cervical secretions may shed new light on the less invasive assessment of endometrial receptivity.

The role of epigenetic mechanisms in the regulation of gene expression in the cyclical endometrium. Clin Epigenetics 2021; 13:116. [PMID: 34034824 PMCID: PMC8146649 DOI: 10.1186/s13148-021-01103-8] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Accepted: 05/13/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The human endometrium is a highly dynamic tissue whose function is mainly regulated by the ovarian steroid hormones estradiol and progesterone. The serum levels of these and other hormones are associated with three specific phases that compose the endometrial cycle: menstrual, proliferative, and secretory. Throughout this cycle, the endometrium exhibits different transcriptional networks according to the genes expressed in each phase. Epigenetic mechanisms are crucial in the fine-tuning of gene expression to generate such transcriptional networks. The present review aims to provide an overview of current research focused on the epigenetic mechanisms that regulate gene expression in the cyclical endometrium and discuss the technical and clinical perspectives regarding this topic. MAIN BODY The main epigenetic mechanisms reported are DNA methylation, histone post-translational modifications, and non-coding RNAs. These epigenetic mechanisms induce the expression of genes associated with transcriptional regulation, endometrial epithelial growth, angiogenesis, and stromal cell proliferation during the proliferative phase. During the secretory phase, epigenetic mechanisms promote the expression of genes associated with hormone response, insulin signaling, decidualization, and embryo implantation. Furthermore, the global content of specific epigenetic modifications and the gene expression of non-coding RNAs and epigenetic modifiers vary according to the menstrual cycle phase. In vitro and cell type-specific studies have demonstrated that epithelial and stromal cells undergo particular epigenetic changes that modulate their transcriptional networks to accomplish their function during decidualization and implantation. CONCLUSION AND PERSPECTIVES Epigenetic mechanisms are emerging as key players in regulating transcriptional networks associated with key processes and functions of the cyclical endometrium. Further studies using next-generation sequencing and single-cell technology are warranted to explore the role of other epigenetic mechanisms in each cell type that composes the endometrium throughout the menstrual cycle. The application of this knowledge will definitively provide essential information to understand the pathological mechanisms of endometrial diseases, such as endometriosis and endometrial cancer, and to identify potential therapeutic targets and improve women's health.

[PMID: 33299465 PMCID: PMC7710412 DOI: 10.1155/2020/9739672] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 10/23/2020] [Accepted: 11/09/2020] [Indexed: 11/17/2022]
Abstract
Background/Aim Erbuzhuyu decoction (EBZYD) is a traditional Chinese medicine (TCM) formula and has been used in infertility treatment. Meanwhile, acupuncture is also used to treat female infertility. However, it is unclear whether EBZYD combined with acupuncture has better therapeutic effect. The aim of this study was to explore the effect of EBZYD combined with acupuncture and investigate its mechanism in superovulation mice. Methods The mice received the treatment of EBZYD, acupuncture, EBZYD combined with acupuncture, or miR-494-3p agomir combined with EBZYD and acupuncture. The blastocysts' number, endometrial microstructure, and endometrial thickness were observed, followed by the detection of endometrial receptivity-related factors, PI3K/Akt/mTOR pathway-related proteins, and miR-494-3p expression using quantitative real-time polymerase chain reaction (qRT-PCR) or western blot. Luciferase reporter assay was performed to confirm the targeting relationship between HOXA10 and miR-494-3p. Results EBZYD combined with acupuncture treatment could increase the number of blastocysts, pinopodes, endometrial thickness, and the expression of endometrial receptivity-related factors, and the treatment effect of EBZYD combined with acupuncture was better than EBZYD or acupuncture alone. In addition, EBZYD combined with acupuncture treatment activated PI3K/Akt/mTOR pathway and inhibited the expression of miR-494-3p. HOXA10 is one of the target genes of miR-494-3p. Overexpression of miR-494-3p reversed the therapeutic effect of EBZYD combined with acupuncture and suppressed the expression of HOXA10 and the activity of PI3K/Akt/mTOR pathway. Conclusion This study suggests that EBZYD combined with acupuncture could improve endometrial receptivity in superovulation mice via miR-494-3p/HOXA10 axis.

Enhanced expression of αVβ3 integrin in villus and extravillous trophoblasts of placenta accreta. Arch Gynecol Obstet 2020; 303:1175-1183. [PMID: 33112993 DOI: 10.1007/s00404-020-05844-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Accepted: 10/13/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Placenta accreta is one of the most serious complications in obstetrics and gynecology. Villous trophoblasts (VT) and extravillous trophoblasts (EVT) play a central role in normal placentation. Placenta accreta is characterized by abnormal invasion of EVT cells through the uterine layers, due to changes in several parameters, including adhesion proteins. Although αvβ3 integrin is a central adhesion molecule, participating in multiple invasive pathological conditions including cancer, data on placenta accreta are lacking. OBJECTIVE To study the expression pattern of αvβ3 integrin in placenta accreta in comparison with normal placentas. STUDY DESIGN We collected tissue samples from placentas defined as percreta, the most severe presentation of placenta accreta and from normal control placentas (n = 10 each). The samples underwent protein extractions for analyses of αvβ3 expression by Western blots (WB) and a parallel tissue assessment by immunohistochemistry (IHC). RESULTS WB results indicated significantly elevated αvβ3 integrin expression in the percreta samples compared to normal placentas. These elevated levels were mainly contributed by EVT cells, as demonstrated by IHC. αvβ3 integrin demonstrated a classical membranal expression in the VT cells, whereas a uniformly distributed expression was documented in the EVT cells. These patterns of the αvβ3 integrin localization were similar in both accreta and normal placental samples. CONCLUSIONS Enhanced αvβ3 integrin expression, mainly in extra villous trophoblasts of placenta percreta, implies for a role of this adhesion molecule in pathological placentation.

Abstract
HOX genes are commonly known for their role in embryonic development, defining the positional identity of most structures along the anterior–posterior axis. In postembryonic life, HOX gene aberrant expression can affect several processes involved in tumorigenesis such as proliferation, apoptosis, migration and invasion. Epigenetic modifications are implicated in gene expression deregulation, and it is accepted that methylation events affecting HOX gene expression play crucial roles in tumorigenesis. In fact, specific methylation profiles in the HOX gene sequence or in HOX-associated histones are recognized as potential biomarkers in several cancers, helping in the prediction of disease outcomes and adding information for decisions regarding the patient’s treatment. The methylation of some HOX genes can be associated with chemotherapy resistance, and its identification may suggest the use of other treatment options. The use of epigenetic drugs affecting generalized or specific DNA methylation profiles, an approach that now deserves much attention, seems likely to be a promising weapon in cancer therapy in the near future. In this review, we summarize these topics, focusing particularly on how the regulation of epigenetic processes may be used in cancer therapy.

Influence of Follicular Fluid and Seminal Plasma on The Expression of Endometrial Receptivity Genes in Endometrial Cells. CELL JOURNAL 2020; 22:457-466. [PMID: 32347039 PMCID: PMC7211287 DOI: 10.22074/cellj.2021.6851] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Accepted: 07/24/2019] [Indexed: 11/04/2022]
Abstract
Objective Endometrial receptivity plays a key role in pregnancy success in assisted reproduction cycles. Recent evidence suggests that seminal plasma (SP) and follicular fluid (FF) influence the uterine endometrium to improve implantation of the embryo and the establishment of pregnancy. In this study, we attempt to assess the influence of FF and SP on the expression levels of main endometrial receptivity genes (HOXA10, HOXA11, ITGAV, ITGB3 and LIF) in endometrial stromal cells. Materials and Methods In this experimental study, SP and FF were collected from 15 healthy fertile men and 15 healthy fertile women, respectively. Tissue specimens of the endometrium were obtained from 12 women undergoing hysterectomy for benign conditions. After endometrial stromal cell isolation and culture, dose- and time-dependent cytotoxic effects of pooled FF and SP on 3D-cultured endometrial cells were evaluated. A second independent set of 12 endometrium samples was treated under determined optimum conditions and evaluated for gene expression analysis using quantitative real-time polymerase chain reaction (qRT-PCR). Results The results of this study indicated that exposure of endometrial stromal cells to FF resulted in the elevated expression of HOXA10 (fold change=2.6, P=0.02), HOXA11 (fold change=3.3, P=0.002), LIF (fold change=4.6, P=0.0003), ITGB3 (fold change=3.5, P=0.012), and ITGAV (fold change=2.8, P=0.001) compared to untreated cells. In addition, we found that SP-treated endometrial cells showed increased mRNA levels of only the LIF gene (fold change=2.5, P=0.008) compared to untreated cells. Conclusion Human SP and FF may modulate the endometrial receptivity and improve the implantation rate in assisted reproduction cycles through the up-regulation of endometrial receptivity genes.
