Metastases are involved in most cancer deaths. Evidence has suggested that cancer cell detachment from primary tumors might occur largely via the mechanism of epithelial-mesenchymal transition (EMT) activated by epigenetic events, but data addressing other possible triggers of detachment, particularly genetic mutations, have been limited. Using the Profile study of cancer genomics at Dana-Farber Cancer Institute, we examined somatic mutations in the EMT genes CDH1 in 5,106 primary carcinomas and CTNNB1 in 7,578 primary carcinomas across 13 anatomic sites: urinary bladder, breast, colon/rectum, endometrium, esophagus, kidney, lung, ovary, pancreas, prostate, skin (non-melanoma), stomach, and thyroid...

The human endometrium undergoes extensive morphological, biochemical and molecular changes under the influence of female sex steroid hormones. Besides the fact that estrogen stimulates endometrial cell proliferation and progesterone inhibits this proliferation and induces differentiation, there is limited knowledge about precise molecular mechanisms underlying human endometrial biology. The importance of paracrine signaling in endometrial physiology explains why in vitro culture of endometrial cells has been challenging...

Background: Genomic studies have revealed that multiple genes are mutated at varying frequency in endometrial cancer (EC); however, the relevance of many of these mutations is poorly understood. An EC-specific recurrent mutation in the MAX transcription factor p.His28Arg was recently discovered. We sought to assess the functional consequences of this hotspot mutation and determine its association with cancer-relevant phenotypes. Methods: MAX was sequenced in 509 endometrioid ECs, and associations between mutation status and clinicopathologic features were assessed...

This report summarized the findings of a case of Erysipelothrix rhusiopathiae infection in a farmed Norwegian Red heifer located in the south-east of Norway. The 2.5-year-old pregnant heifer was found dead after a short episode of inappetence. On gross exam, the heifer was severely dehydrated with uterine torsion. Microscopically, necrosis of the endometrium was present throughout the uterus along with presence of intralesional Gram-positive bacteria, interstitial nephritis, and pyelonephritis. E. rhusiopathiae was isolated from the uterus and placenta and was also demonstrated by immunohistochemistry (IHC) in the uterus, placenta, and kidney...

Seminal plasma (SP) is considered as a vehicle to carry sperm into female reproductive tract, of which functions have not been completely understood. This study aimed to identify the function of seminal exosomes on porcine endometrium. Exosomes were isolated from the sperm-rich fraction of boar semen and were confirmed by the expression of exosome marker HSP70 and size distribution using nano-sight tracking analysis. Porcine endometrial epithelial cells (EECs) were then treated with seminal exosomes, and RNA extracted were subjected to global expression analysis...

BACKGROUND: Second-generation endometrial ablation has been demonstrated safe for abnormal uterine bleeding treatment in premenopausal women, who have completed childbearing, in short-stay surgical centers and in physicians' offices. However, no standard regarding anesthesia exists and practice varies depending on physician or patient preference and hospital policy and setting. OBJECTIVE: To evaluate whether local anesthetic, in combination with general anesthesia, affects postoperative pain and associated narcotic use following endometrial ablation...

The incorporation of endothelial progenitor cells (EPCs) into newly developing blood vessels contributes to the vascularization of endometriotic lesions. here, we analyzed whether cyclooxygenase (COX)-2 signaling regulates this vasculogenic process. Endometriotic lesions were surgically induced in irradiated FVB/N mice, which were reconstituted with bone marrow from FVB/N-TgN (Tie2/green fluorescent protein (GFP)) 287 Sato mice. The animals received β-estradiol 17-valerate once a week and were daily treated with the selective COX-2 inhibitor parecoxib (25 mg/kg) or vehicle (control) over 7 and 28 days...

The genetic profile is one of the major possible causes of spindle cell sarcoma. Irradiation has also been linked to this type of cancer. This means that if tissues have already been irradiated for other types of cancer, they can afterwards develop this form of sarcoma. Also, previous radiotherapy can determine specific genetic alterations, which result to uncontrolled cell division, that is neoplasia. We report one such cause in a female patient 80 years old with a uterus adenocarcinoma (endometrioid type) FIGO Stage IC, who had been treated with surgical resection and pelvic irradiation...

The control of complement activation within embryo-endometrium environment is critical for embryo survival. Cell evasion from complement attack requires interaction of complement regulatory proteins (CRPs) with cell adhesion αvβ3 integrin. We aim to compare the expression of CRPs in endometria of women with and without endometriosis and to examine the molecular interaction of decay accelerating factor (DAF) with αvβ3 integrin. Endometrial expression of Membrane cofactor protein (CD46), Decay accelerating factor (DAF), Membrane attack complex inhibitory factor (CD59) and β3 integrin subunit were determined through menstrual cycle by immunohistochemistry...

Endometrial osseous metaplasia (EOM) is a rare condition characterised by the presence of bone in the uterine cavity. Some patients with this condition present with secondary infertility due to the presence of a foreign body in the endometrium. We report a case of a 39-year-old woman who presented with secondary infertility due to EOM. EOM is a rare cause of infertility that can be easily managed by hysteroscopic removal of the bony fragments.

Lipolysis-stimulated lipoprotein receptor (LSR) is a novel molecule present at tricellular contacts which recruits tricellulin (TRIC), a molecular component of tricellular tight junctions (tTJs). LSR and TRIC are colocalized with the bicellular tight junction (bTJ) protein claudin (CLDN)-1-based tight junction strands at tricellular corners. Knockdown of LSR in normal epithelial cells affects tTJ formation and the epithelial barrier function. In cancer cells knockdown of LSR has been demonstrated to increase cell invasion...

Endometriosis is a multifactorial pathology. Trans-tubal reflux theory remains valid. Genetic and epigenetic factors associated with immunological perturbations are involved. The role of endocrine disruptors is discussed although epidemiological studies are contradictory. Therapeutics are primarily based on hormonal treatments but better understanding of pathophysiology should allow targeted non-hormonal therapy. The clinical examination is sometimes negative, which should not eliminate the diagnosis and imposes complementary examinations as best as possible by referents...
