Genome-wide association study of nausea and vomiting during pregnancy in Japan: the TMM BirThree Cohort Study. BMC Pregnancy Childbirth 2024; 24:209. [PMID: 38509478 PMCID: PMC10953086 DOI: 10.1186/s12884-024-06376-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 02/27/2024] [Indexed: 03/22/2024] Open
Abstract
BACKGROUND Nausea and vomiting during pregnancy (NVP) and hyperemesis gravidarum (HG), common conditions affecting most pregnant women, are highly heritable and associated with maternal and fetal morbidity. However, the pathologies underlying NVP and HG and their associated loci are scarce. METHODS We performed genome-wide association studies (GWAS) of NVP in pregnant women (n = 23,040) who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study in Japan from July 2013 to March 2017. Participants were divided into discovery (n = 9,464) and replication (n = 10,051) stages based on the platform used for their genotyping. Loci that achieved the genome-wide significance level (p < 5.0 × 10- 8) in the discovery stage were selected for genotyping in the replication stage. A meta-analysis integrating the discovery and replication stage results (n = 19,515) was conducted. NVP-related variables were identified as categorical or continuous. RESULTS GWAS analysis in the discovery phase revealed loci linked to NVP in two gene regions, 11q22.1 (rs77775955) and 19p13.11 (rs749451 and rs28568614). Loci in these two gene regions have also been shown to be associated with HG in a White European population, indicating the generalizability of the GWAS analyses conducted in this study. Of these, only rs749451 and rs28568614 at 19p13.11 reached the genome-wide suggestive level (p < 1.0 × 10- 5) in the replication stage; however, both loci were significant in the meta-analysis. CONCLUSIONS NVP-related loci were identified in the Japanese population at 11q22.1 and 19p13.11, as reported in previous GWAS. This study contributes new evidence on the generalizability of previous GWAS on the association between genetic background and NVP.

Life Sci 2021; 286:120053. [PMID: 34656555 DOI: 10.1016/j.lfs.2021.120053] [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: 02/17/2021] [Revised: 06/09/2021] [Accepted: 10/11/2021] [Indexed: 10/20/2022]
Abstract
AIMS Explore the effects of heat stress and psychological stress combined exposure on the uterus and its underlying mechanisms. MAIN METHODS Sixty female Sprague-Dawley rats were randomly assigned to four groups: control group, psychological stress group, high ambient temperature group, and high ambient temperature combined with psychological stress group. All treatments were administered for two weeks. During this period, the estrous cycle, body weights and rectal temperature were measured regularly. Then, ovarian weight coefficient, serum estradiol (E2) and progesterone (P) concentration, uterine histomorphological alterations, levels of tumor necrosis factor alpha (TNF-α), malondialdehyde (MDA) and superoxide dismutase (SOD), and the expressions of ovarian hormone receptors, leukemia inhibitory factor (LIF) and its receptor, homeobox gene A10 (HoxA10), Wnt5a, Wnt7a, β-catenin, and P-β-cateninY142 in the uterus and endometrium were detected. KEY FINDINGS High temperature combined with psychological stress lead to body weight, body temperature, ovarian hormones and estrus cycle disorder, uterine gland ducts expansion and endometrial thickness reduction, and the decreased expression of endometrial receptivity markers (LIF and HoxA10). Further, disturbed expression of E2 and P receptors in endometrium, elevated MDA and TNF-α levels, and decreased Wnt5a, Wnt7a and P-β-cateninY142 content were found. Our data suggested that co-exposure to high temperature and psychological stress could aggravate uterine damage probably by inducing ovarian hormonal disorder and the subsequent oxidative stress and inflammation, and reduce the endometrial function through suppressing Wnt signaling. SIGNIFICANCE This will provide the scientific basis for improving female reproductive health, and preventing and treating reproductive disorders.

A Transcriptome Analysis: Various Reasons of Adverse Pregnancy Outcomes Caused by Acute Toxoplasma gondii Infection. Front Physiol 2020; 11:115. [PMID: 32140111 PMCID: PMC7042390 DOI: 10.3389/fphys.2020.00115] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2019] [Accepted: 01/31/2020] [Indexed: 12/14/2022] Open
Abstract
Background Toxoplasma gondii (T. gondii) is an obligate intracellular parasite, which can affect the pregnancy outcomes in infected females by damaging the uterus, and the intrauterine environment as well as and the hypothalamus resulting in hormonal imbalance. However, the molecular mechanisms underlying the parasite-induced poor pregnancy outcomes and the key genes regulating these mechanisms remain unclear. Therefore, this study aimed to analyze the gene expression in the mouse’s uterus following experimentally-induced acute infection with T. gondii RH strain. Three groups of female mice were intraperitoneally injected with tachyzoites as follow; 3 days before pregnancy (FBD6), after pregnancy (FAD6), and after implantation (FID8) as the experimental groups. Another corresponding three groups served as control, were injected with normal saline at the same time. Transcriptome analysis of the total RNA extracted from both infected and non-infected mouse uterus samples was performed using RNA sequencing (RNA-Seq). Results The three experimental groups (FBD6, FAD6, and FID8) had a total of 4,561, 2,345, and 2,997 differentially expressed genes (DEGs) compared to the controls. The significantly upregulated and downregulated DEGs were 2,571 and 1,990 genes in FBD6, 1,042 and 1,303 genes in FAD6 and 1,162 and 1,835 genes in FID8 group, respectively. The analysis of GO annotation, and KEGG pathway showed that DEGs were mainly involved in anatomical structure development, transport, cell differentiation, embryo development, hormone biosynthetic process, signal transduction, immune system process, phagosome, pathways in cancer, and cytokine-cytokine receptor interaction pathways. Conclusion T. gondii infection can induce global transcriptomic changes in the uterus that may cause pregnancy hypertension, destruct the intrauterine environment, and hinder the normal development of placenta and embryo. Our results may help to understand the molecular mechanisms of the acute T. gondii infection, which could promote the development of new therapeutics or prophylactics for toxoplasmosis in pregnancy.

Abstract
In mice, implantation always occurs towards the antimesometrial side of the uterus, while the placenta develops at the mesometrial side. What determines this particular orientation of the implanting blastocyst remains unclear. Uterine glands are critical for implantation and pregnancy. In this study, we showed that uterine gland development and active Wnt signaling activity is limited to the antimesometrial side of the uterus. Dkk2, a known antagonist of Wnt signaling, is only present at the mesometrial side of the uterus. Imaging of whole uterus, thick uterine sections (100-1000µm), and individual glands revealed that uterine glands are simple tubes with branches that are directly connected to the luminal epithelium and are only present towards the antimesometrial side of the uterus. By developing a unique mouse model targeting the uterine epithelium, we demonstrated that Wnt/β-catenin signaling is essential for prepubertal gland formation and normal implantation, but dispensable for postpartum gland development and regeneration. Our results for the first time have provided a probable explanation for the antimesometrial bias for implantation.

The transcription factor ccaat/enhancer binding protein β (C/EBPβ) and miR-27a regulate the expression of porcine Dickkopf2 (DKK2). Sci Rep 2015; 5:17972.

Abstract
Using Affymetrix porcine Gene-Chip analyses, we found that Dickkopf2 (DKK2), a WNT antagonist, is differentially expressed in pre-ovulatory follicles between Large White and Chinese Taihu sows. This study aims to identify the regulatory factors responsible for DKK2 expression. Deletion fragment and mutation analyses identified DKK2-D3 as the porcine DKK2 core promoter. There were four C/EBPβ binding sites within the DKK2 core promoter. The C allele that results from a spontaneous alteration (DKK2 c.−1130 T > C) in the core promoter was associated with a higher total number born (TNB) and a higher number born alive (NBA) in all parities in a synthetic pig population. This was possibly the result of a change in C/EBPβ binding ability, which was confirmed using chromatin immunoprecipitation (ChIP) and electrophoretic mobility shift assays (EMSA). Moreover, C/EBPβ specifically bound to and activated the DKK2 promoter, as revealed by mutation analysis, overexpression and RNA interference (RNAi) experiments. We also confirmed that miR-27a is a negative regulator of the DKK2 gene using miR-27a overexpression and inhibition experiments and mutation analyses. RTCA xCELLigence experiments showed that miR-27a suppressed Chinese hamster ovary (CHO) cell proliferation by down-regulating DKK2 gene expression. Taken together, our findings suggest that C/EBPβ and miR-27a control DKK2 transcription.
