Exploration of Diagnostic Deubiquitinating Enzymes in Endometriosis and Its Immune Infiltration.

The mechanism involved in the pathogenesis of endometriosis is poorly understood. The purpose of this study is to identify key deubiquitinating enzymes (DUBs) for endometriosis diagnosis and elucidate the possible mechanism, offering novel insights for noninvasive early diagnosis and treatment. Four gene expression datasets were employed from the Gene Expression Omnibus to identify differentially expressed genes (DEGs) between endometriosis and normal controls.

Maternal inheritance of glucose intolerance via oocyte TET3 insufficiency.

Diabetes mellitus is prevalent among women of reproductive age, and many women are left undiagnosed or untreated. Gestational diabetes has profound and enduring effects on the long-term health of the offspring. However, the link between pregestational diabetes and disease risk into adulthood in the next generation has not been sufficiently investigated.

Alterations of the Human Gut Microbiota in Intrahepatic Cholestasis of Pregnancy.

Background And Aims: Women with severe intrahepatic cholestasis of pregnancy (ICP) are at higher risks of fetal complications and without effective treatments. Changes in gut microbiota in pregnancy were found to be related to the altered intestinal bile acid composition, so we aimed to explore the alterations of microbiota in the gut of ICP patients.

Methods: A total of 90 women were recruited, including 45 ICP patients and 45 healthy controls.

An Mutation in a Large Chinese Kindred With Familial Adenomatous Polyposis Was Identified Using Both Next Generation Sequencing and Simple STR Marker Haplotypes.

Background: Familial adenomatous polyposis (FAP) is an autosomal dominant disorder characterized primarily by the development of numerous adenomatous polyps in the colon and a high risk for colorectal cancer. FAP is caused by germline mutations of the adenomatous polyposis coli () gene. The proband in this family was a 39-year-old female patient with the pathologic diagnosis of adenomatous polyps, and then a five-generation kindred with FAP was characterized in the following years.

Balloon tamponade for successful emergency cervical cerclage.

Aim: To illustrate the method of emergency cerclage with the balloon tamponade and demonstrate the efficacy of this surgery method.

Methods: Procedures of the balloon tamponade assisted emergency cerclage were reviewed in detail and outcomes of 39 patients treated with this way were evaluated.

Results: From 2017 to 2019, emergency cerclage was successfully performed in 39 patients with a dilated cervix and bulging fetal membranes, assisted by the balloon tamponade.

[Prognosis of fetuses with cystichygroma and nuchal translucency/nuchal fold thickening on prenatal echography].

Objective: To analyze the prognosis of fetuses with cystic hygroma (CH) or nuchal translucency (NT) or nuchal fold (NF) thickening detected by prenatal echography.

Methods: From January 2014 to December 2015, 124 fetuses with CH and NT/NF thickening on prenatal echography were enrolled from Women's Hospital of Zhejiang University School of Medicine. The basic clinical information, ultrasonic results, pregnancy outcomes and newborn follow-ups were analyzed.

Environmentally relevant levels of bisphenol A affect uterine decidualization and embryo implantation through the estrogen receptor/serum and glucocorticoid-regulated kinase 1/epithelial sodium ion channel α-subunit pathway in a mouse model.

Objective: To investigate whether bisphenol A (BPA) exposure is associated with uterine decidualization and embryo implantation failure in mice.

Design: Experimental animal study and in vitro study.

Setting: University-based infertility center.

Altered methylations of H19, Snrpn, Mest and Peg3 are reversible by developmental reprogramming in kidney tissue of ICSI-derived mice.

Although the prevalence of Intracytoplasmic sperm injection (ICSI) has increased year by year, there remains concern about the safety of these procedures because of reports of the increased risk for imprinting disorders. Previous research has demonstrated that gonadotropin stimulation contributes to an increased incidence of epimutations in ICSI-derived mice. However, the epimutations in ICSI offspring after removing the effect of gonadotropin stimulation and the possibility that epimutations are reversible by developmental reprogramming has not been investigated.

Effect of CDKN2A/B rs4977756 polymorphism on glioma risk: a meta-analysis of 16 studies including 24077 participants.

So far, epidemiological studies have been performed to investigate the association of CDKN2A/B rs4977756 polymorphism and glioma risk. However, the results from different studies remain inconsistent. To clarify these conflicts and to quantitatively evaluate the effect of rs4977756 polymorphism on glioma risk, a meta-analysis was conducted using relevant published clinical studies about rs4977756 polymorphisms and glioma risk.

miR-20a mediates temozolomide-resistance in glioblastoma cells via negatively regulating LRIG1 expression.

Aims: Resistance to temozolomide (TMZ) is a major obstacle in the treatment of glioblastoma multiforme (GBM). MiRNAs is considered as an important modulator of drug resistance in many cancers. Here, we aimed to elucidate the relationship between miR-20a, its predicted target genes leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) and TMZ resistance in GBM.

An overview of studies on psychological well-being in children born following assisted reproductive technologies.

Over the course of the past 35 years, assisted reproductive technologies (ARTs) have been increasingly used worldwide, while debates on their safety have been generated. Birth defects and imprinting disorders were reported in previous research. Thus, the psychological development of children born following ARTs has become a major concern nowadays.

Altered expressions and DNA methylation of imprinted genes in chromosome 7 in brain of mouse offspring conceived from in vitro maturation.

Objectives: The aim of this research was to investigate the effects of in vitro maturation (IVM) on the expression of imprinted genes in offspring, and to identify possible regulatory mechanisms for these genes.

Results: By using an IVM mouse model, mRNA expression of H19 was found down-regulated and Kcnq1ot1 was up-regulated in brains of IVM offspring. Of the differentially methylated regions (DMRs) of H19, CpG island 3 was found to have higher DNA methylation levels in IVM group compared with the control group; in contrast, Kcnq1ot1 showed a significant reduction in DNA methylation in IVM mice by using the bisulfite sequence PCR and pyrosequencing.

Altered expression of Armet and Mrlp51 in the oocyte, preimplantation embryo, and brain of mice following oocyte in vitro maturation but postnatal brain development and cognitive function are normal.

Despite the efforts to recapitulate the follicle environment, oocytes from in vitro maturation (IVM) have poorer developmental potential than those matured in vivo and the effects on the resultant offspring are of concern. The aim of this study was to determine altered gene expression in oocytes following IVM and to evaluate the expression of the arginine rich, mutated in early stage of tumors gene (Armet) and mitochondrial ribosomal protein L51 (Mrpl51) in embryos and brains of fetal/postnatal mice and the brain development of IVM offspring. An IVM mouse model was established while oocytes matured in vivo were used as the controls.

Effects of In Vitro Maturation on Histone Acetylation in Metaphase II Oocytes and Early Cleavage Embryos.

In vitro maturation (IVM) of oocyte is an effective procedure for avoiding ovarian hyperstimulation syndrome in patients with polycystic ovaries (PCOS) during in vitro fertilization (IVF). To investigate the influences of IVM on epigenetic reprogramming and to search for the possible reasons for the lower rates of fertilization and cleavage in IVM oocytes, we examined the expression of two enzymes controlling histone acetylation, histone acetyltransferase GCN5 (GCN5) and histone deacetylase 1 (HDAC1), as well as their common target, acetyl-histone H3 (Ac-H3), in mouse metaphase II (MII) oocytes and preimplantation embryos. Results showed that IVM downregulated the protein expression of GCN5 in MII oocytes and two-cell embryos and changed the distribution of GCN5 in two-cell embryos.
