Inhibition of tumor cell proliferation in human uterine leiomyomas by vitamin D via Wnt/β-catenin pathway.
2018
To assess the effect of vitamin D (VitD) on human uterine leiomyomas through Wnt/β-catenin pathway inhibition, apoptosis induction, and cell growth arrest.A prospective study comparing leiomyoma vs. myometrium tissues. Paired design study comparing human uterine leiomyoma primary (HULP) cells treated with or without VitD.University hospital.Human uterine leiomyoma and myometrium were collected from women (aged 35-52 years) without hormonal treatment.Samples were collected from women undergoing surgery due to symptomatic uterine leiomyoma pathology.Uterine leiomyoma and myometrium tissues were analyzed by western blot (WB) to determine proliferation, Wnt/β-catenin, and apoptosis pathways.

Long-term vitamin D treatment decreases human uterine leiomyoma size in a xenograft animal model
2019
Objective To study the effects of short- and long-term vitamin D treatment on uterine leiomyomas in vivo through cell proliferation, extracellular matrix (ECM) degradation, and apoptosis. Design Preclinical study of human leiomyoma treatment with vitamin D in an nonhuman animal model. Setting Hospital and university laboratories. Patient(s)/Animal(s) Human leiomyomas were collected from patients and implanted in ovariectomized NOD-SCID mice. Intervention(s) Mice were treated with vitamin D (0.5 μg/kg/d or 1 μg/kg/d) or vehicle for 21 or 60 days. Main Outcome Measure(s) Vitamin D effect in xenograft tissue was assessed by monitoring tumor size (18F-FDG positron-emission tomography/computeriz…
Inhibition of KIF20A by BKS0349 reduces endometriotic lesions in a xenograft mouse model
2019
AbstractSeveral studies have suggested a possible etiological association between ovarian endometriosis and ovarian cancer. Evidence has shown that KIF20A overexpression might confer a malignant phenotype to ovarian tumors by promoting proliferation and inhibiting apoptosis. However, no data about the role of KIF20A in endometriosis have been described. In this study, the human endometrium (n = 4) was transfected by mCherry adenovirus and intraperitoneally implanted in mice. Subsequently, mice were divided in three groups (n = 8/group) that were treated with Vehicle, BKS0349 (KIF20A-antagonist) or cabergoline (dopamine receptor agonist) for 21 days. mCherry-labeled endometriotic lesions wer…

P–543 Inhibition of cell proliferation and extracellular matrix formation in human uterine leiomyomas by 5-aza–2’-deoxycitidine via Wnt/ β-catenin pa…
2021
Abstract Study question Is DNA methylation reversion through DNA methyltransferases (DNMT) inhibitors, such as 5-aza–2’-deoxycitidine, a potential therapeutic option for treatment of patients with uterine leiomyomas (UL)? Summary answer 5-aza–2’-deoxycitidine reduces proliferation and extracellular matrix (ECM) formation by inhibition of Wnt/ β-catenin pathway on UL cells, suggesting DNMT inhibitors as an option to treat UL. What is known already: UL is a multifactorial disease with an unclear pathogenesis and inaccurate treatment. Aberrant DNA methylation have been found in UL compared to myometrium (MM) tissue, showing hypermethylation of tumor suppressor genes, which contributes to the d…
Proteomic analysis of extracellular vesicles secreted by primary human epithelial endometrial cells reveals key proteins related to embryo implantati…
2022
Abstract Background Successful implantation is dependent on coordination between maternal endometrium and embryo, and the role of EVs in the required cross-talk cell-to-cell has been recently established. In this regard, it has been reported that EVs secreted by the maternal endometrium can be internalized by human trophoblastic cells transferring their contents and enhancing their adhesive and invasive capacity. This is the first study to comprehensively evaluate three EV isolation methods on human endometrial epithelial cells in culture and to describe the proteomic content of EVs secreted by pHEECs from fertile women. Methods Ishikawa cells and pHEECs were in vitro cultured and hormonall…

Vitamin D as an effective treatment in human uterine leiomyomas independent of mediator complex subunit 12 mutation.
2021
Objective To study whether vitamin D (VitD) inhibits cell proliferation and Wnt/β-catenin and transforming growth factor−β (TGFβ) signaling pathways in uterine leiomyomas independent of mediator complex subunit 12 (MED12) mutation status. Design Prospective study comparing leiomyoma vs. myometrial tissues and human uterine leiomyoma primary (HULP) cells treated with or without VitD and analyzed by MED12 mutation status. Setting Hospital and university laboratories. Patient(s) Women with uterine leiomyoma without any treatment (n = 37). Intervention(s) Uterine leiomyoma and myometrium samples were collected from women undergoing surgery because of symptomatic leiomyoma pathology. Main Outcom…
Single-cell RNA sequencing of oocytes from ovarian endometriosis patients reveals a differential transcriptomic profile associated with lower quality
2018
Abstract STUDY QUESTION Do oocytes from women with ovarian endometriosis (OE) have a different transcriptomic profile than those from healthy women? SUMMARY ANSWER Oocytes from endometriosis patients, independently of whether they came from the affected ovary, exhibited a differential transcriptomic profile compared to oocytes from healthy egg donors. WHAT IS KNOWN ALREADY Studies of endometriosis have sought to determine whether OE affects oocyte quality. While many reports indicate that oocytes recovered from endometriotic ovaries may be affected by the disease, other studies have found no significant differences among oocyte/embryo quality and fertilization, implantation and pregnancy ra…
Novel therapeutic targets to improve IVF outcomes in endometriosis patients: a review and future prospects
2020
AbstractBACKGROUNDPatients with endometriosis often experience infertility and have poor IVF outcomes, with low fertilization and pregnancy rates. Although many theories have tried to explain the mechanisms underlying infertility in these patients, none of them is conclusive.OBJECTIVE AND RATIONALEIn this review, we discuss the pathologic mechanisms through which endometriosis likely leads to infertility along with the therapeutic options used to date to treat endometriosis-related infertility and, thereby, to improve IVF outcomes in patients with endometriosis.SEARCH METHODSWe performed a comprehensive literature search of clinical outcomes in endometriosis and the molecular mechanisms con…
