Abstract
OBJECTIVES Arterial embolization of myomas (AEM) is controversial because of the changes that occur in the extracellular matrix (ECM) of the endometrium and its effect on gestational success in infertile patients desiring reproductive capability. Therefore, we performed this study on the expression of genes in the ECM of the endometrium, such as those coding metalloproteinases (MMP), before and 6 months after embolization of the uterine arteries. METHODS Seven women with leiomyomas were evaluated, and MMP3 and MMP10 levels were measured. The women underwent pelvic nuclear magnetic resonance (NMR), examination, and endometrial biopsy between the 20th and 24th day of the menstrual cycle, and pre- and post-AEM (after 6 months). For data analysis, the Cq comparative method, also known as the 2-ΔΔCT method, was used to calculate the relative quantities of MMP gene expression among the samples collected. RESULTS There was a significant decrease by 9.52 times in the expression of MMP3 (p=0.007), and a non-significant change in the expression of MMP10 (p=0.22) in post-AEM-treated women than pre-AEM-treated women. CONCLUSIONS The results suggest that ECM continues to undergo tissue remodeling 6 months after AEM, at least with regard to MMP3 expression, suggesting that AEM affects the ECM for at least 6 months after the procedure.

Abstract
Abnormal uterine bleeding (AUB) is a chronic, debilitating and common condition affecting one in four women of reproductive age. Current treatments (conservative, medical and surgical) may be unsuitable, poorly tolerated or may result in loss of fertility. Selective progesterone receptor modulators (SPRMs) influence progesterone-regulated pathways, a hormone critical to female reproductive health and disease; therefore, SPRMs hold great potential in fulfilling an unmet need in managing gynaecological disorders. SPRMs in current clinical use include RU486 (mifepristone), which is licensed for pregnancy interruption, and CDB-2914 (ulipristal acetate), licensed for managing AUB in women with leiomyomas and in a higher dose as an emergency contraceptive. In this article, we explore the clinical journey of SPRMs and the need for further interrogation of this class of drugs with the ultimate goal of improving women's quality of life.

Abstract
Nuclear factor of activated T-cells (NFAT5) is a tissue specific, osmoadaptive transcription factor essential for the control of hydration homeostasis in mammalian cells. Nuclear factor of activated T-cells regulates osmolyte transporters aldo-keto reductase family 1 member B1 (AKR1B1) and solute carrier family 5 member 3 (SLC5A3) to maintain fluid equilibrium in cells. The osmotic potential of the extracellular matrix of leiomyomas is attributed to the role of proteoglycans. In leiomyoma cells, NFAT5 is overexpressed compared to myometrial cells. The selective progesterone receptor modulator, ulipristal acetate, has been reported to decrease the size of leiomyomas in clinical trials. When treated with ulipristal acetate, both patient leiomyoma tissue and leiomyoma cells grown in 3-dimensional cultures show a decrease in the expression of NFAT5 protein, solute transporters AKR1B1 and SLC5A3, and results in an associated decline in the expression of proteoglycans, versican, aggrecan, and brevican. In summary, ulipristal acetate induces changes in leiomyoma cell osmoregulation which result in a decrease in proteoglycan expression.

Abstract
AIM to investigate the molecular mechanisms and morphological substrate of reduced uterine leiomyoma in patients receiving the selective progesterone receptor modulator (SPRM) ulipristal acetate for 3 months, by estimating the immunohistochemical expression of the markers steroid receptor coactivator 1 (SRC-1), nuclear receptor corepressor 1 (NCoR-1), ER, PgR, Ki-67, p16, TGF-β, and VEGF in tumor tissue. SUBJECTS AND METHODS The investigation enrolled 75 women with uterine leiomyoma, menorrhagias, and anemia. Group 1 included 40 patients who were treated with ulipristal for 3 months, followed by laparoscopic myomectomy. Group 2 consisted of 35 patients who underwent surgery without previous preparation. The intra- and postoperative parameters and molecular and morphological changes in the myomatous nodules were comparatively analyzed in both groups. RESULTS After 3 months of therapy initiation, menorrhagia completely ceased, myomatous nodules decreased in size (p<0.05), hemoglobin levels were elevated (p<0.01), and total intraoperative blood loss and operative time decreased in all the patients in Group 1. The morphological substrate of partial leiomyoma reduction was leiomyocyte apoptosis and dystrophy, tumor stroma sclerosis and hyalinosis with diminished Ki-67 expression and elevated p16 in the smooth muscle cells, trophic nodular tissue disorders exhibited by vascular wall sclerosis and lower VEGF and TGF-β expression, and leiomyocyte hormonal reception dysregulation that made itself evident through the reduced expression of SRC-1 with the unchanged expression of PR and ER and the maintained level of NCoR-1. CONCLUSION The molecular mechanisms of tumor reduction involved the reduced Ki-67 expression and elevated p16, lower VEGF and TGF-β, diminished SRC-1 expression with the maintained level of PR, ER, and NCoR-1. Overall, this is suggestive of enhanced apoptosis and reduced leiomyoma proliferation and angiogenesis induced by SPRM and indicative of the expediency of using ulipristal acetate as a preoperative agent for organ-sparing surgery in reproductive-aged patients with uterine myoma, menorrhagias, and anemia.

Abstract
Uterine leiomyomas are benign tumors arising from the myometrium and largely prevalent in the woman's reproductive years. The majority of women with leiomyomas either remain asymptomatic or develop symptoms gradually over time. When patients are symptomatic, the nature of their complaints is often attributable to the number, size, and/or location of their fibroids. Depending on a patient's symptomatology and reproductive plans, treatment options include expectant management, medical management (hormonal and non-hormonal), or surgical management (myomectomy or hysterectomy).

Abstract
BACKGROUND Uterine leiomyoma is the most common benign tumor in women and is thought to arise from the clonal expansion of a single myometrial smooth muscle cell transformed by a cellular insult. Leiomyomas cause a variety of symptoms, including abnormal uterine bleeding, pelvic pain, bladder or bowel dysfunction, and recurrent pregnancy loss, and are the most common indication for hysterectomy in the USA. A slow rate of cell proliferation, combined with the production of copious amounts of extracellular matrix, accounts for tumor expansion. A common salient feature of leiomyomas is their responsiveness to steroid hormones, thus providing an opportunity for intervention. METHODS A comprehensive search of PUBMED was conducted to identify peer-reviewed literature published since 1980 pertinent to the roles of steroid hormones and somatic stem cells in leiomyoma, including literature on therapeutics that target steroid hormone action in leiomyoma. Reviewed articles were restricted to English language only. Studies in both animals and humans were reviewed for the manuscript. RESULTS Estrogen stimulates the growth of leiomyomas, which are exposed to this hormone not only through ovarian steroidogenesis, but also through local conversion of androgens by aromatase within the tumors themselves. The primary action of estrogen, together with its receptor estrogen receptor α (ERα), is likely mediated via induction of progesterone receptor (PR) expression, thereby allowing leiomyoma responsiveness to progesterone. Progesterone has been shown to stimulate the growth of leiomyoma through a set of key genes that regulate both apoptosis and proliferation. Given these findings, aromatase inhibitors and antiprogestins have been developed for the treatment of leiomyoma, but neither treatment results in complete regression of leiomyoma, and tumors recur after treatment is stopped. Recently, distinct cell populations were discovered in leiomyomas; a small population showed stem-progenitor cell properties, and was found to be essential for ovarian steroid-dependent growth of leiomyomas. Interestingly, these stem-progenitor cells were deficient in ERα and PR and instead relied on the strikingly higher levels of these receptors in surrounding differentiated cells to mediate estrogen and progesterone action via paracrine signaling. CONCLUSIONS It has been well established that estrogen and progesterone are involved in the proliferation and maintenance of uterine leiomyoma, and the majority of medical treatments currently available for leiomyoma work by inhibiting steroid hormone production or action. A pitfall of these therapeutics is that they decrease leiomyoma size, but do not completely eradicate them, and tumors tend to regrow once treatment is stopped. The recent discovery of stem cells and their paracrine interactions with more differentiated cell populations within leiomyoma has the potential to provide the missing link between developing therapeutics that temper leiomyoma growth and those that eradicate them.

Abstract
CONTEXT Clinical evidence supports a role for progestins in the growth of leiomyomata (fibroids). The mechanism(s) for this is thought to involve gene regulation via the nuclear progesterone receptors. Recently a mitochondrial progesterone receptor (PR-M) has been identified with evidence of a progesterone/progestin-dependent increase in cellular respiration. This observation raises a possible new mechanism whereby progesterone/progestin may affect the growth of fibroids. OBJECTIVE The goals of this research were to determine differential expression of PR-M in normal myometrium compared with the edge of a fibroid within the same uterus, to demonstrate a progestin-dependent increase in mitochondria membrane potential using an immortalized human myometrial cell line and to examine mitochondrial membrane potential in transfected cells expressing the complete coding sequence of PR-M. DESIGN Protein levels of PR-M, PR-B, PR-A, mitochondrial porin, and glyceraldehyde-3-phosphate dehydrogenase were determined in the myometrium and adjacent edge of a fibroid in 10 subjects undergoing hysterectomy for benign indications. Mitochondrial membrane potential was determined by fluorescent emission of 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolecarbocyanide iodine in hTERT-HM cells treated with R5020 and in transfected hTERT-HM cells determined by the fluorescent emission of tetramethylrhodamine methyl ester. RESULTS Higher levels of PR-M and mitochondrial porin were found in the fibroid edge compared with adjacent myometrium. Progestin increased mitochondrial membrane potential in hTERT-HM cells, which was not affected by a translation inhibitor. This effect was exaggerated in hTERT-HM cells expressing PR-M after transient transfection. CONCLUSION These studies suggest a mechanism whereby progesterone/progestin may affect the growth of fibroids by altering mitochondrial activity.

Abstract
Uterine leiomyomas (UL) are the most frequent symptomatic human tumors. Nevertheless, their molecular pathogenesis is not yet fully understood. To learn more about the biology of these common neoplasms and their response to treatment, cell cultures derived from UL are a frequently used model system, but until recently appropriate genetic markers confirming their origin from the tumor cell population were lacking for most UL, i.e., those not displaying karyotypic abnormalities. The identification of MED12 mutations in the majority of UL makes it possible to trace the tumor cell population during in vitro passaging in the absence of cytogenetic abnormalities. The present study is addressing the in vitro survival of cells carrying MED12 mutations and its association with karyotypic alterations. The results challenge numerous in vitro studies into the biology and behavior of leiomyomas. Cells of one genetic subtype of UL, i.e., those with rearrangements of the high mobility AT-hook 2 protein gene (HMGA2), seem to be able to proliferate in vitro for many passages whereas tumor cells from the much more frequent MED12-mutated lesions barely survive even the first passages. Apparently, for the most frequent type of human UL no good in vitro model seems to exist because cells do not survive culturing. On the other hand, this inability may point to an Achilles' heel of this type of UL.

Abstract
BACKGROUND Uterine fibroids are the most common gynecologic tumors in women of reproductive age yet the etiology and pathogenesis of these lesions remain poorly understood. Age, African ancestry, nulliparity and obesity have been identified as predisposing factors for uterine fibroids. Symptomatic tumors can cause excessive uterine bleeding, bladder dysfunction and pelvic pain, as well as associated reproductive disorders such as infertility, miscarriage and other adverse pregnancy outcomes. Currently, there are limited noninvasive therapies for fibroids and no early intervention or prevention strategies are readily available. This review summarizes the advances in basic, applied and translational uterine fibroid research, in addition to current and proposed approaches to clinical management as presented at the 'Advances in Uterine Leiomyoma Research: 3rd NIH International Congress'. Congress recommendations and a review of the fibroid literature are also reported. METHODS This review is a report of meeting proceedings, the resulting recommendations and a literature review of the subject. RESULTS The research data presented highlights the complexity of uterine fibroids and the convergence of ethnicity, race, genetics, epigenetics and environmental factors, including lifestyle and possible socioeconomic parameters on disease manifestation. The data presented suggest it is likely that the majority of women with uterine fibroids will have normal pregnancy outcomes; however, additional research is warranted. As an alternative to surgery, an effective long-term medical treatment for uterine fibroids should reduce heavy uterine bleeding and fibroid/uterine volume without excessive side effects. This goal has not been achieved and current treatments reduce symptoms only temporarily; however, a multi-disciplined approach to understanding the molecular origins and pathogenesis of uterine fibroids, as presented in this report, makes our quest for identifying novel targets for noninvasive, possibly nonsystemic and effective long-term treatment very promising. CONCLUSIONS The Congress facilitated the exchange of scientific information among members of the uterine leiomyoma research and health-care communities. While advances in research have deepened our knowledge of the pathobiology of fibroids, their etiology still remains incompletely understood. Further needs exist for determination of risk factors and initiation of preventive measures for fibroids, in addition to continued development of new medical and minimally invasive options for treatment.

Abstract
In addition to the estrogen receptor, the progesterone receptor plays an important role in the growth of uterine fibroids. Several selective progesterone receptor modulators (SPRMs) have been evaluated for medical treatment of uterine fibroids and, because of safety issues, some molecules were stopped during clinical development. However, in 2012, ulipristal acetate received the approval for a pre-surgical treatment of uterine fibroids. Clinical trials with ulipristal acetate for long-term medical treatment of uterine fibroids are ongoing. This review article describes the action of SPRMs at the progesterone receptor level and the mechanism of action on the fibroid tissue. A review of the published clinical trials is performed, including the current evidence of efficacy on uterine fibroid symptom management, size reduction and tolerability. The therapeutic potential of SPRMs for uterine fibroids is discussed.

CONTEXT Uterine leiomyomas (fibroids or myomas) are benign tumors of the uterus and are clinically apparent in up to 25% of reproductive-age women. Heavy or abnormal uterine bleeding, pelvic pain or pressure, infertility, and recurrent pregnancy loss are generally associated with leiomyoma. Although surgical and radiological therapies are frequently used for the management of this tumor, medical therapies are considered the first-line treatment of leiomyoma. EVIDENCE ACQUISITION AND SYNTHESIS A review was conducted of electronic and print data comprising both original and review articles on pathophysiology and medical treatments of uterine leiomyoma retrieved from the PubMed or Google Scholar database up to June 2012. These resources were integrated with the authors' knowledge of the field. CONCLUSION To date, several pathogenetic factors such as genetic factors, epigenetic factors, estrogens, progesterone, growth factors, cytokines, chemokines, and extracellular matrix components have been implicated in leiomyoma development and growth. On the basis of current hypotheses, several medical therapies have been investigated. GnRH agonist has been approved by US Food and Drug Administration for reducing fibroid volume and related symptoms. In addition, the FDA also approved an intrauterine device, levonorgestrel-releasing intrauterine system (Mirena), for additional use to treat heavy menstrual bleeding in intrauterine device users only. Currently, mifepristone, asoprisnil, ulipristal acetate, and epigallocatechin gallate have been shown to be effective for fibroid regression and symptomatic improvement which are all in clinical trial. In addition, some synthetic and natural compounds as well as growth factor inhibitors are now under laboratory investigation, and they could serve as future therapeutic options.

Abstract
The majority of symptomatic uterine fibroids are currently treated by surgical interventions (myomectomy or hysterectomy) or radiological treatments (uterine artery embolisation or focussed ultrasound surgery). None of these treatments is a panacea, and what is conspicuous is the lack of an effective long-term medical therapy for a disorder so common among women of reproductive age. It has been known for some time that progesterone and its receptors enhance proliferative activity in fibroids and this has raised the possibility that anti-progestins and (PRMs) could be useful in the medical management of fibroids. Some of the compounds which have produced promising results in recent clinical trials or research studies include mifepristone, CDB-4124 (telapristone), CP-8947, J-867 (asoprisnil) and CDB-2914 (ulipristal acetate or UA). UA has recently completed Phase III clinical trials with very encouraging results, and has now acquired a licence for clinical use in Europe. While considerable research has yet to be done on the long-term safety and efficacy of UA there is nevertheless good reason for optimism on the emergence of effective medical therapy in the form of UA and possibly other PRMs.

Abstract
Selective progesterone receptor modulators (SPRMs) have been developed since the late 70s when mifepristone was first described. They act through nuclear progesterone receptors and can have agonist or mixed agonist antagonist actions depending on the cell and tissue. Mifepristone has unique major antagonist properties allowing its use for pregnancy termination. Ulipristal acetate has been marketed in 2009 for emergency contraception and has been recently approved for preoperative myoma treatment. Further perspectives for SPRMs use include long term estrogen free contraception, endometriosis treatment. However long term applications will be possible only after confirmation of endometrial safety.

Abstract
Small non-coding RNAs termed microRNAs (miRNAs) are mediators of post-transcriptional gene silencing and are involved in all aspects of cell biology. Progesterone receptors (PR) are intimately involved in the normal physiology and diseases of hormone responsive tissues including the uterus and the breast. Recent evidence suggests that hormone regulated miRNAs play a substantial role in hormone receptor mediated gene regulation. However, relatively little is known regarding miRNAs regulated by PR or that target PR as compared to those regulated by or targeting estrogen receptors (ER). We summarize the state of current knowledge regarding miRNAs and PR action. We also delineate how progesterone regulated miRNAs might provide an additional level of control and fine tuning of gene regulation by hormone receptors and also facilitate cell- and tissue-specific gene regulation PR.

Abstract
BACKGROUND Growth factors are proteins secreted by a number of cell types that are capable of modulating cellular growth, proliferation and cellular differentiation. It is well accepted that uterine cellular events such as proliferation and differentiation are regulated by sex steroids and their actions in target tissues are mediated by local production of growth factors acting through paracrine and/or autocrine mechanisms. Myometrial mass is ultimately modified in pregnancy as well as in tumour conditions such as leiomyoma and leiomyosarcoma. Leiomyomas, also known as fibroids, are benign tumours of the uterus, considered to be one of the most frequent causes of infertility in reproductive years in women. METHODS For this review, we searched the database MEDLINE and Google Scholar for articles with content related to growth factors acting on myometrium; the findings are hereby reviewed and discussed. RESULTS Different growth factors such as epidermal growth factor (EGF), transforming growth factor-α (TGF-α), heparin-binding EGF (HB-EGF), acidic fibroblast growth factor (aFGF), basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF), platelet-derived growth factor (PDGF) and TGF-β perform actions in myometrium and in leiomyomas. In addition to these growth factors, activin and myostatin have been recently identified in myometrium and leiomyoma. CONCLUSIONS Growth factors play an important role in the mechanisms involved in myometrial patho-physiology.

Abstract
INTRODUCTION Uterine leiomyoma is the most common benign tumor in women during the reproductive years. Menorrhagia is the common symptom and accounts for the most frequent indication for hysterectomy. Thus, development of a novel drug for non-surgical treatment of uterine leiomyoma is needed for the betterment of women's health. AREA COVERED This review introduces a translational research initiated by use of the levonorgestrel-releasing intrauterine system (LNG-IUS) for contraceptive purposes. During follow-up, a patient informed that heavy menstrual bleeding caused by uterine myoma was strikingly reduced after the insertion of device. The patient's unexpected comment led the authors to perform clinical trials of LNG-IUS for the management of menorrhagia in women with uterine myomas and striking reduction in menorrhagia was obtained by the use of LNG-IUS. MRI examination, however, revealed that the volume of myomas decreased in some, but increased in the other instances. This unexpected finding with MRI directed the authors to characterize the effects of progesterone (P4) and progesterone receptor modulators (PRMs) on uterineleiomyoma cell growth in vitro. EXPERT OPINION In consistence with the in vitro data obtained, randomized controlled clinical trials of PRMs in patients with uterine leiomyomas at several institutions have demonstrated that oral administration of PRMs (asoprisnil and ulipristal) for 3 months reduced leiomyoma volume, resulting in a significant improvement of the associated symptoms. However, a novel pattern of PRM-associated endometrial changes was recognized in the endometrial pathology, demonstrating unusual epithelial types not seen in the normal menstrual cycle of a premenstrual woman. Thus, follow-up studies to determine whether the novel endometrial changes remain, disappear or progress to something else are needed for the possible long-term use of PRMs for the treatment of uterine leiomyoma.

Abstract
OBJECTIVE Selective progesterone receptor modulators (SPRMs), such as asoprisnil (J867) and ulipristal (CDB-2914), have been shown to reduce fibroid volume in vivo and to induce apoptosis in vitro. CDB-4124 (telapristone), a SPRM with different side groups, also reduced fibroid volume in vivo, and we hypothesized that this SPRM would also cause apoptosis in cultured fibroid cells. METHODS Immortalized, progesterone receptor-positive fibroid cells, known to be capable of apoptosis, were grown to 80% confluence in serum-containing media. Cells were then treated for 48 hours in serum-free media with 0, 10, 100, or 1000 nmol/L CDB-4124. Actinomycin-D and staurosporine were used as positive controls to induce apoptosis. Apoptosis was quantified using a TUNEL-fluorescein kit. Images were captured with a widefield-fluorescence microscope and analyzed using MetaMorph image analysis software. To validate results, Western blots of total cell lysates were probed for cleaved caspase-3 (c-CASP3). Experiments were repeated 3 times using independent cell batches. RESULTS Analysis of 19 712 nuclei indicated 14.8% ± 10.9% (mean ± SEM), 8.4% ± 4.6%, 8.2% ± 4.7%, and 9.3% ± 6.3% apoptosis in 0, 10, 100, and 1000 nmol/L CDB-4124-treated cells, respectively. There was no evidence of elevated c-CASP3 over vehicle control after treatment with CDB-4124. CONCLUSION CDB-4124 did not significantly induce apoptosis in cultured fibroid cells under the conditions described suggesting apoptosis may not be the main pathway responsible for CDB-4124-induced fibroid shrinkage. Variations in SPRM biological effects may be due to differences in fibroid source cells, binding kinetics, or extracellular matrix characteristics, and can be exploited in further investigations of the mechanisms of action of SPRMs in fibroid biology.
