Abstract
Introduction: Raloxifene (Ral) is the oldest SERM (selective oestrogen receptor modulators) for treatment of breast cancer and osteoporosis. Its oestrogen-modulating effects have been shown in breast and uterus. Since there is little available data on direct Ral effect on the human endometrium, the aim of present study was to investigate the Ral effect on the growth and angiogenesis of the human endometrium of healthy and endometriosis subjects in an in vitro three-dimensional (3D) tissue culture model. Material and methods: Endometrial biopsies from healthy ( n = 9) and endometriosis ( n = 7) patients (endometriotic) were taken and were cut into 1 × 1 mm fragments and implanted between two layers of fibrin jell made by fibrinogen solution (3 mg/ml in medium 199+thrombin). Tissue cultures were performed in 24-wel culture plates. Each biopsy was divided into control wells which received M199 supplemented with FBS (5%) and experimental wells which received same media containing one of raloxifene doses (0.1, 1 and 10 μM). Endometrial tissues were photographed at the beginning and the end of the study period (21 days). Tissue growth and angiogenesis were determined by a scoring system. Results: In control (0), 0.1, 1 and 10 μM Ral, the growth score of normal human endometrial tissues were 1.99, 1.72, 1.53 and 1.12 ( p = 0.02) and angiogenesis percent were 29.6%, 31.28%, 33% and 11.5%. The Growth scores of the endometriotic endometrium were 1.92, 1.82, 1.92 and 1.1 ( p = 0.008) and angiogenesis percent were 36.6%, 16.6%, 44% and 12.5% respectively. Conclusion: Raloxifene showed a different dose dependent effect on endometrial and endometriotic tissue.

Inhibitory effect of resveratrol on the growth and angiogenesis of human endometrial tissue in an In Vitro three-dimensional model of endometriosis. Reprod Biol 2020; 20:484-490. [PMID: 32896495 DOI: 10.1016/j.repbio.2020.07.012] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Revised: 07/28/2020] [Accepted: 07/31/2020] [Indexed: 12/20/2022]
Abstract
Endometriosis is a chronic estrogen-dependent disorder and one of the most common causes of infertility in women. Resveratrol (RES) is a polyphenolic and phytoestrogenic compound with anti-oxidative, anti-inflammatory, anti-angiogenic, and anti-estrogenic properties. The aim of the present study was to investigate the effect of different concentrations of RES on human endometrial growth and angiogenesis in an in vitro three-dimensional (3D) model of endometriosis.Human endometrial tissues of endometriosis (endometriotic) and normal (endometrial) subjects (n = 9/groups) were biopsied in sterile conditions and cut into 1 × 2 mm pieces. Tissue fragments of each biopsy were given concentrations of 0 (control), 10, 50, 100 and 200 μM RES for 21 days in 3D culture condition using fibrin as an extracellular matrix. Scoring methods were used for tissue changes, including; cellular invasion, monolayer formation and angiogenesis. Nitric oxide (NO) was measured using Griess's reaction, and quantitative real-time polymerase chain reaction (qRT-PCR) was used to evaluate the apoptotic gene expression.The mean of growth scores of endometriotic and endometrial tissue showed a significant dose dependent inhibition (P < 0.05). The levels of NO also significantly decreased in different groups. Apoptotic genes (P53, Bax, Bcl2 and caspase 3) and Sirt1 showed a significant increase in various concentrations of RES in both tissues (P < 0.05).RES exert dose- and time-dependent inhibitory effects on human endometrial tissue, and its higher doses suggested it as a natural supplement to inhibit the growth and treatment of endometriosis.

Abstract
The human endometrium undergoes sequential phases of shedding of the upper functionalis zone during menstruation, followed by regeneration of the functionalis zone from the remaining basalis zone cells, and secretory differentiation under the influence of the ovarian steroid hormones estradiol (E2) and progesterone (P4). This massive tissue regeneration after menstruation is believed to arise from endometrial stromal and epithelial stem cells residing in the basal layer of the endometrium. Although many endometrial pathologies are thought to be associated with defects in these stem cells, studies on their identification and regulation are limited, primarily due to lack of easily accessible animal models, as these processes are unique to primates. Here we describe a robust new method to study endometrial regeneration and differentiation processes using human endometrial tissue slice cultures incorporating an air-liquid interface into a 3D matrix scaffold of type I collagen gel, allowing sustained tissue viability over three weeks. The 3D collagen gel-embedded endometrial tissue slices in a double-dish culture system responded to ovarian steroid hormones, mimicking the endometrial changes that occur in vivo during the menstrual cycle. These changes included the E2-induced upregulation of Ki-67, estrogen receptor (ER), and progesterone receptor (PR) in all endometrial compartments and were markedly suppressed by both P4 and E2 plus P4 treatments. There were also distinct changes in endometrial morphology after E2 and P4 treatments, including subnuclear vacuolation and luminal secretions in glands as well as decidualization of stromal cells, typical characteristics of a progestational endometrium in vivo. This long-term slice culture method provides a unique in vivo-like microenvironment for the study of human endometrial functions and remodeling during early pregnancy and experiments on stem cell populations involved in endometrial regeneration and remodeling. Furthermore, this model has the potential to enable studies on several endometrial diseases, including endometrial cancers and pregnancy complications associated with defects in endometrial remodeling.

Abstract
The majority of endometrial cancers are detected early with a favourable prognosis. However, for patients with advanced disease, chemotherapy response rates and overall survival remains poor. The endometrial cancer population is typically elderly with multiple co-morbidities and aggressive cytotoxic therapy may be hazardous. Therefore, there is an urgent need to define optimal treatment strategies for advanced and recurrent disease and personalise therapy based on individual tumour and patient characteristics. Three-dimensional (3D) models that preserve the tumour microenvironment and tumour-stromal interactions are increasingly important for translational research with the advent of immunotherapy and molecularly targeted agents. 3D patient-relevant pre-clinical models in endometrial cancer include spheroids, patient-derived organoids, microfluidic systems, patient-derived xenografts and patient-derived explants. Here we present a review of available 3D modelling systems in endometrial cancers, highlighting their current use, advantages, disadvantages and applications to translational research with a focus on the power of the patient-derived explant platform.

Abstract
OBJECTIVE To evaluate the effects of letrozole on ovarian size and steroidogenesis in vivo, as well as on proliferation and steroidogenesis of theca-interstitial cells alone and in coculture with granulosa cells using an in vitro model. DESIGN In vivo and in vitro studies. SETTING Research laboratory. ANIMAL(S) Immature Sprague-Dawley female rats. INTERVENTION(S) In vivo effects of letrozole were studied in intact rats receiving either letrozole (90-day continuous-release SC pellets, 400 μg/d) or placebo pellets (control group). In in vitro experiments, theca cells were cultured alone or in coculture with granulosa cells in the absence or presence of letrozole. MAIN OUTCOME MEASURE(S) Deoxyribonucleic acid synthesis was determined by thymidine incorporation assay; steroidogenesis by mass spectrometry; and steroidogenic enzyme messenger RNA (mRNA) expression by polymerase chain reaction. RESULT(S) In vivo, letrozole induced an increase in ovarian size compared with the control group and also induced a profound increase of androgen, LH levels, and Cyp17a1 mRNA expression. Conversely, a decrease in Star, Cyp11a1, and Hsd3b1 transcripts was observed in letrozole-exposed rats. In vitro, letrozole did not alter either theca cell proliferation or Cyp17a1 mRNA expression. Similarly, letrozole did not affect Cyp17a1 transcripts in granulosa-theca cocultures. CONCLUSION(S) These findings suggest that letrozole exerts potent, but indirect, effect on growth of rat ovary and dramatically increases androgen levels and Cyp17a1 mRNA expression, the key enzyme regulating the androgen biosynthesis pathway. The present findings reveal novel mechanisms of action of letrozole in the rat ovary.

Abstract
OBJECTIVE To compare the estradiol production and P450 aromatase messenger RNA (mRNA) expression of cultured luteinized granulosa cells and the effect of letrozole on these parameters between women with and without endometriosis. DESIGN In vitro assays. SETTING Reproductive medical center. PATIENT(S) Patients undergoing in vitro fertilization (IVF): 23 patients with endometriosis and 19 controls without endometriosis. INTERVENTION(S) Luteinized granulosa cells examined for estradiol levels and P450 aromatase mRNA expression in conditioned media at different letrozole concentrations of 0.0, 0.1, 1.0, and 10.0 μmol/L. MAIN OUTCOME MEASURE(S) Estradiol levels of the conditioned medium measured with an enzyme-linked immunosorbent assay (ELISA) kit and P450 aromatase mRNA expression determined by quantitative reverse transcription-polymerase chain reaction (QT RT-PCR). RESULT(S) The estradiol concentration of the conditioned media and P450 aromatase mRNA expression in the endometriosis group were statistically significantly lower than that of the control group, irrespective of letrozole concentrations. A statistically significant reduction of these two parameters was observed in both endometriosis and control groups at letrozole concentrations of 1 μmol/L and 10 μmol/L, but there were no statistically significant differences between letrozole concentrations of 1 μmol/L and 10 μmol/L. The number of high-quality embryos in the endometriosis group was statistically significantly lower than that of the control group. CONCLUSION(S) Lower estradiol production and P450 aromatase mRNA expression of cultured granulosa cells were found in women with endometriosis. Letrozole in the conditioned media further reduced these parameters.

Abstract
Background Uterine leiomyoma is the most common benign tumor in reproductive-age women. Each leiomyoma is thought to be a benign monoclonal tumor arising from a single transformed myometrial smooth muscle cell; however, it is not known what leiomyoma cell type is responsible for tumor growth. Thus, we tested the hypothesis that a distinct stem/reservoir cell-enriched population, designated as the leiomyoma-derived side population (LMSP), is responsible for cell proliferation and tumor growth. Principal Findings LMSP comprised approximately 1% of all leiomyoma and 2% of all myometrium-derived cells. All LMSP and leiomyoma-derived main population (LMMP) but none of the side or main population cells isolated from adjacent myometrium carried a mediator complex subunit 12 mutation, a genetic marker of neoplastic transformation. Messenger RNA levels for estrogen receptor-α, progesterone receptor and smooth muscle cell markers were barely detectable and significantly lower in the LMSP compared with the LMMP. LMSP alone did not attach or survive in monolayer culture in the presence or absence of estradiol and progestin, whereas LMMP readily grew under these conditions. LMSP did attach and survive when directly mixed with unsorted myometrial cells in monolayer culture. After resorting and reculturing, LMSP gained full potential of proliferation. Intriguingly, xenografts comprised of LMSP and unsorted myometrial smooth muscle cells grew into relatively large tumors (3.67±1.07 mm3), whereas xenografts comprised of LMMP and unsorted myometrial smooth muscle cells produced smaller tumors (0.54±0.20 mm3, p<0.05, n = 10 paired patient samples). LMSP xenografts displayed significantly higher proliferative activity compared with LMMP xenografts (p<0.05). Conclusions Our data suggest that LMSP, which have stem/reservoir cell characteristics, are necessary for in vivo growth of leiomyoma xenograft tumors. Lower estrogen and progesterone receptor levels in LMSP suggests an indirect paracrine effect of steroid hormones on stem cells via the mature neighboring cells.

Abstract
AbstractHormonal control in the development of the normal endometrium is of the utmost importance. It is well established that the two main hormones involved in this process are estradiol and progesterone, which are also implicated in the pathological conditions concerning endometriosis and endometrial carcinoma. There are two types of endometrial carcinoma: type I which represents 80%–90% is hormone-dependent, whereas the remainder is type II and is hormone-independent. The endometrial tissue contains all the enzymatic systems in the formation and transformation of the various hormones, including aromatases, sulfatases, sulfotransferases, hydroxysteroid dehydrogenases, hydroxylases, and glucuronidases. It is interesting to note that increased sulfatase activity is correlated with severity of endometriosis. An increased sulfatase/sulfotransferase ratio represents a poor prognosis in patients with endometrial carcinoma. Treatment with hormone replacement therapy (estrogens+progestogens), as well as with tibolone, is most effective in protecting this tissue by climacteric alterations, owing to the significant decrease of ovarian hormones. In conclusion, enzymatic control can open appealing perspectives to protect this organ from possible pathological alterations.
