Abstract Purpose Endometriosis is a chronic gynecological disorder associated with pain symptoms and infertility. The expression of microRNA miR‐29c‐3p is dysregulated in endometriosis. We aimed to identify novel molecular targets of miR‐29…

Abstract Study question What are the shared and unique cell type -specific molecular pathways in endometriosis and adenomyosis? Summary answer Our analysis focuses on hormonal pathways and those regulating cell proliferation and apoptosis, …

BACKGROUND: Endometriosis is a common, gynaecological disease characterised by the presence of endometrial-like cells growing outside the uterus. Lesions appear at multiple locations, present with variation in appearance, size and depth of …

Trimethylation of histone H3 at lysine 4 (H3K4me3) is a marker of active promoters. Broad H3K4me3 promoter domains have been associated with cell type identity, but H3K4me3 dynamics upon cellular stress have not been well characterized. We …

The stem cell marker and RNA-binding protein Musashi-1 is overexpressed in endometriosis. Musashi-1-siRNA knockdown in Ishikawa cells altered the expression of stem cell related genes, such as OCT-4. To investigate the role of both human Mu…

Hydroxysteroid (17beta) dehydrogenase type 1 (HSD17B1) is an enzyme that converts estrone to estradiol, while adenomyosis is an estrogen-dependent disease with poorly understood pathophysiology. In the present study, we show that mice unive…

Abstract Study question Do Musashi proteins mechanistically contribute to the pathogenetic properties of endometriotic cells? Summary answer Silencing of Musashi-1 and Muashi-2 reduces the expression of stemness-related genes, inhibits sphe…

Endometriosis is a common inflammatory estrogen-dependent gynecological disorder, associated with pelvic pain and reduced fertility in women. Several aspects of this disorder and its cellular and molecular etiology remain unresolved. We hav…

BACKGROUND: The cancer antigen 125 (CA125) immunoassay (IA) does not distinguish epithelial ovarian cancer (EOC) from benign disease with the sensitivity needed in clinical practice. In recent studies, glycoforms of CA125 have shown potenti…

Human reproductive success depends on a properly decidualized uterine endometrium that allows implantation and the formation of the placenta. At the core of the decidualization process are endometrial stromal fibroblasts (ESF) that differen…

BACKGROUND: The Sialyl-Thomsen-nouveau antigen (STn) is abundantly produced on many types of human epithelial cancers including epithelial ovarian cancer (EOC). We previously developed an EOC-specific lectin sandwich immunoassay (CA125MGL) …

Abnormal synthesis and metabolism of sex steroids is involved in the pathogenesis of various human diseases, such as endometriosis and cancers arising from the breast and uterus. Steroid biosynthesis is a multistep enzymatic process proceed…

Abstract Human reproductive success depends on a properly decidualized uterine endometrium that allows implantation and the formation of the placenta. At the core of the decidualization process are endometrial stromal fibroblasts (ESF) that…

An LC-MS/MS method was developed and validated to analyze simultaneously estrogens (estradiol, E2; estrone, E1), androgens (testosterone, T; androstenedione, A4; dehydroepiandrosterone, DHEA), progestagens (17a-hydroxypregnenolone, 17OHP5; …

STUDY QUESTION: What is the role of SFRP2 in endometriosis? SUMMARY ANSWER: SFRP2 acts as a canonical WNT/CTNNB1 signaling agonist in endometriosis, regulating endometriosis lesion growth and indicating endometriosis lesion borders together…

BACKGROUND: Measurement of serum cancer antigen 125 (CA125) is the standard approach for epithelial ovarian cancer (EOC) diagnostics and follow-up. However, the clinical specificity is not optimal because increased values are also detected …

Aberrant sex steroid signaling is suggested to promote endometriosis growth by several mechanisms, and the tissue concentrations of sex steroids are key determinants of the hormone action. However, their concentrations are only superficiall…

New molecular information on potential therapeutic targets or tools for noninvasive diagnosis for endometriosis are important for patient care and treatment. However, surprisingly few efforts have described endometriosis at the protein leve…

CONTEXT: Aberrant estrogen synthesis and metabolism have been suggested to increase local estradiol (E2) concentration in endometriosis and thus to promote the growth of the lesions. However, tissue estrogen concentrations within the endome…

A fast and sensitive LC-MS/MS method for the quantitative analysis of seven steroid hormones in 150 μl of human serum was developed and validated. The following compounds were included: 17α-hydroxypregnenolone, 17α-hydroxyprogesterone, andr…

Of women of reproductive age, 6 to 10% are estimated to be affected by endometriosis. Growth of tissue resembling the uterine mucosa outside the uterine cavity often causes severe menstrual pain, chronic pelvic pain and infertility for the …

Steroidal estrogens are lipid-soluble compounds that are able to pass through the plasma membrane of cells by diffusion.According to the current knowledge, the three main naturally occurring estrogens are estrone (E 1 ), estradiol (E 2 ), a…
