Uterine immune mediators and lipid profiles of the preimplantation embryo and endometrial tissue in Holstein cows supplemented with rumen-protected methionine and observed neutrophil extracellular trap (NET) formation in the bovine endometrial tissue
… extracellular trap (NET) formation in the endometrial tissue, multiparous Holstein cows (n = 20) were randomly assigned to two treatments starting at 21 d before calving until 73 days in milk (DIM). Treatments were: CON (n = 9, no supplementation, TMR with a Lys:Met = 3.5:1) and MET (n = …

Persistent Oxidative Damage Accounts for the Origin of Mutations Observed in Uterine Pathology
Endometrial adenocarcinoma and leiomyomas are prevalent disorders of the same organ. Endometrial cancer, the most prevalently diagnosed gynecological cancer, is associated with mutated PTEN tumor suppressor gene. The type I endometrial cancer PTEN hotspot mutation involves a cytosine to guanine …

In vitro progesterone and estrone synthesis by the porcine placenta and endometrium at 30, 60 and 90 days of gestation
… monophosphate ( cAMP) on porcine placental and endometrial production of progesterone (P₄), testosterone (T) and estrone (E₁) at 30, 60 and 90 days of gestation. Duplicate 300 mg samples of placenta, endometrium or both (co-incubation) were incubated in medium199 containing either no P₅, P₅, P₅ …

Control of endometrial secretion in cattle and production of transgenic swine
Endometrial tissue was collected from cows to determine effects of day of the estrous cycle, location of the ovulatory structure and progesterone (P₄) on endometrial protein secretion. Day 0 (estrus) endometrial tissue released more protein than tissue collected on d 9, 14 or 18. Protein synthesis …

Control of uteroglobin gene expression
… extracts of progesterone-stimulated uterine endometrial tissue. Also discovered was an activity capable of suppressing the DNA binding activity. In this work, the repressor activity was purified from nuclear extracts. The cause of this activity was found to be fragments of genomic DNA. The …

Regulation of endometrial repair and its impact on heavy menstrual bleeding
… (HMB). The mechanisms and factors involved in endometrial repair are still to be fully elucidated. Endometrial function is governed by the ovarian hormones and pre-menstrually progesterone levels decline as the corpus luteum regresses. Consequently, the synthesis of prostaglandins (PG) is …

Manipulating Embryonic Development and Endometrial Function in Ruminants
… was established, ewes were bred. Conceptus and endometrial tissue were collected at D 14 of pregnancy, and samples were processed for RNA-sequencing analysis. There were no differences in pregnancy rate, ovulation rate, or pregnancies/ovulation between obese and lean animals. At an RPKM …

Gene Expression in Endometrial Tissues of Normal Mares and Mares With Delayed Uterine Clearance
… to evaluate gene expression of selected genes in endometrial tissue samples taken from three categories of mares (young fertile [YF], older clinically normal [ON] and older susceptible [OS]). The genes assayed in this research were oxytocin receptor, PGF2á receptor and progesterone receptor. The …

Zyklusabhängige Expression und Lokalisation der Isoform C des Progesteronrezeptors im humanen Endometrium im Vergleich mit den Isoformen B und A
… study, the expression of these isoforms in human endometrial tissue was investigated by Western Blot analysis. In comparative experiments different antibodies against the progesterone receptor have been tested and it could clearly be shown that the isoform C can only be detected by antibodies …

ROLES OF HAND2 TRANSCRIPTION FACTOR IN UTERINE RECEPTIVITY AND DECIDUALIZATION
… the mother endometrium. At the same time, the endometrial tissue undergoes the process of decidualization to support the anchoring of the blastocyst and provides the blastocyst with nutrition until the fully functional placenta is formed. Although the process of implantation and decidualization …

Analysis of the Role of the Transcription Factor C/EBPbeta in Controlling Uterine Functions During Early Pregnancy
… the integration of steroid hormone signaling, endometrial tissue remodeling and maternal-fetal communications. A successful pregnancy is the outcome of the timely integration of these events during the early stages of implantation. The involvement of ovarian steroid hormones, estrogen (E) and …

Effects of somatic cell nuclear transfer on transcripts related to IGF signaling, EGF signaling and cell adhesion during the peri-implantation period in cattle
… this hypothesis, we analyzed transcriptomes of endometrial tissue and extra-embryonic tissue (EET) collected from gestation day (GD)-18 and GD-34 bovine pregnancies (SCNT and artificial insemination-derived pregnancies) using RNAseq, and endometrial transcription of 16 preselected genes using …

HORMONAL AND MECHANICAL CUES ON DYNAMIC CELLULAR PROCESSES IN ENDOMETRIOSIS
… 10 women characterized by the abnormal growth of endometrial tissue outside of the uterus. Endometriotic tissues attach to the peritoneal mesothelium lining the pelvic cavity to establish harmful lesions and implants in ectopic sites, leading to pelvic pain, infertility, and reduced quality of …

Genetic Imbalances in Endometriosis Detected by Oligonucleotide-Array Based Comparative Genomic Hybridization
… Characterized by the growth and proliferation of endometrial tissue outside of the uterine cavity, it is a complex condition with varying degrees of severity and can affect multiple regions of the body with symptoms ranging from a total lack of symptoms to debilitating pain and infertility. The …

Regulation of glucose transporters in sheep placenta
… predominantly localised to maternal villous and endometrial tissue. By late gestation oGLUT1 mRNA was most strongly localised to maternal syncytiotrophoblast and villous tissue, whereas oGLUT3 was predominantly localised to fetal trophoblast cells. Placental oGLUT expression was regulated …

Role of mast cells in women's health and disorders of the endometrium
… cycle, the human endometrium undergoes extensive tissue remodelling under the influence of ovarian-derived hormones. The endometrium has well defined stromal and epithelial compartments with the former containing both a well-developed vasculature as well as a diverse population of immune cells. …

The Effects of Preovulatory Estradiol on the Uterine Environment and Conceptus Survival From Fertilization to Maternal Recognition of Pregnancy
… caruncular (CAR) and intercaruncular (INCAR) endometrial tissue to determine relative abundance of select glucose transporters (SLC2A1, SLC2A4, SLC2A5, and SLC5A1). There was no difference in conceptus recovery rate between estrus and no estrus cows (P = 0.20; 48% vs 29%) or between replicates …

Global alterations of the epigenetic landscape define endometrial receptivity and provide a hallmark for endometriosis
… of infertility. The endometrium is also the tissue chiefly involved in the aetiology of endometriosis, a condition in which endometrial tissue is found outside the womb where it forms lesions. Endometriosis affects ~10% of women of reproductive age, can cause severe pain and poses an …

Trans-vaginal ultrasound diagnosis of adenomyosis with histologic correlation
Adenomyosis, defined as the presence of ectopic endometrial tissue in the myometrium, is a cause of morbidity in afflicted women. Classically it presents with menorrhagia, dysmenorrhoea and dyspareunia. Traditionally the diagnosis has been by histology of post-hysterectomy specimens with reported …
