Abstract
PURPOSE Magnetic resonance - high-intensity focused ultrasound (MR-HIFU) is a noninvasive treatment option for symptomatic uterine leiomyomas. Currently, pretreatment MRI is used to assess tissue characteristics and predict the most likely therapeutic response for individual patients. However, these predictions still entail significant uncertainties. The impact of tissue properties on therapeutic outcomes remains poorly understood and detailed knowledge of the histological effects of ultrasound ablation is lacking. Investigating these aspects could aid in optimizing patient selection, enhancing treatment effects and improving treatment outcomes. METHODS AND MATERIALS We present seven patients who underwent MR-HIFU treatment for leiomyoma followed by second-line surgical treatment. Tissue samples obtained during the surgery were stained with hematoxylin and eosin, Masson's trichrome and Herovici to evaluate general morphology, fibrosis and collagen deposition of leiomyomas. Immunohistochemical CD31, Ki-67 and MMP-2 stainings were performed to study vascularization, proliferation and matrix metalloproteinase-2 protein expression in leiomyomas, respectively. RESULTS The clinical characteristics and radiological findings of the leiomyomas prior to treatment as well as qualitative histological findings after the treatment are presented and discussed in the context of current literature. A tentative model for volume reduction is presented. CONCLUSION These findings provide insights into potential factors contributing to suboptimal therapeutic outcomes and the variability in histological changes following treatment.

Abstract
Uterine fibroids (UFs) (leiomyomas or myomas) are the most common clonal neoplasms of the uterus in women of reproductive age worldwide. UFs originate from myometrium consist of smooth muscle and fibroblast components, in addition to a substantial amount of fibrous extracellular matrix which all contribute to the pathogenetic process. Current treatments are primarily limited to surgical and interventional. Here, we have established a novel and promising organoid model from both normal and patient myometrial stem cells (MMSCs). MMSCs embedded in Matrigel in stem cell media swiftly formed organoids which successfully proliferate and self-organized into complex structures developing a sustainable organoid culture that maintain their capacity to differentiate into the different cell types recapitulating their tissue of origin and shows responsiveness to the reproductive hormones (estrogen and progesterone). Gene expression analysis and structural features indicated the early onset of uterine fibrosis led to the accumulation of extracellular matrix suggesting the potential use of this model in better understanding of the pathophysiology associated with UFs and inventing novel therapeutics for the treatment of UFs.

Abstract
OBJECTIVE To characterize the method by which angiogenesis occurred in three-dimensional (3D) leiomyoma xenografts, and to assess the impact of hypoxia on two-dimensional (2D) and 3D myometrial and leiomyoma cells and leiomyoma xenografts in vivo. DESIGN Laboratory study. SETTING Academic research. PATIENT(S) Cell cultures from patient-matched myometrial and leiomyoma tissues. INTERVENTION(S) In vivo 3D leiomyoma xenografts from ovariectomized mice treated with gonadal hormones; myometrial and leiomyoma cells in 2D and 3D growth formats exposed to 1% oxygen. MAIN OUTCOME MEASURE(S) Protein expression. RESULT(S) Blood vessels in the xenograft estradiol group are identified with anti-mouse/anti-rat CD31/PECAM-1 antibody. Hormone-stimulated 3D leiomyoma xenografts stain positively for adrenomedullin (ADM). Myometrial cells exposed to 1% oxygen demonstrated an increase in hypoxia-inducible factor (HIF)-1α at 6 hours and a marked increase at 24 hours. Under normoxic conditions, leiomyoma cells at 6 hours show increased expression of HIF-1α, which is further increased at 24 hours. Leiomyoma cells under hypoxia demonstrated a 1.14-fold decrease in HIF-1α expression at 6 hours and no change at 24 hours. Hypoxic myometrium decreased the proangiogenic protein ADM expression at 6 hours and showed a >1.5-fold increase at 24 hours. Normoxic leiomyoma decrease ADM at 24 hours and showed a >1.5-fold increase at 24 hours of hypoxia. CONCLUSION(S) Hypoxia-induced HIF-1α expression facilitates angiogenesis in 3D xenografts in vivo by increasing the expression of the proangiogenic protein ADM. Angiogenesis contributes to the viability and extended survival of these xenografts. Furthermore, 2D myometrial and leiomyoma cells increase HIF-1α and ADM expression in vitro under hypoxic conditions.

Abstract
OBJECTIVE To characterize the potential interaction between interleukin-6 (IL6), Janus kinase (JAK)-signal transducer and activator of transcription (STAT)-3 (JAK/STAT3) pathway, and Transforming growth factor beta (TGFβ)-3 , and to determine whether such cross-talk was a contributing factor in the dysregulation of type I collagen production in leiomyomas. DESIGN Laboratory study. SETTING University research laboratory. PATIENTS None. INTERVENTIONS Exposure of leiomyoma and myometrial cell lines to IL6 and STAT3 activators/inhibitors. Western immunoblot analysis and immunohistochemistry. MAIN OUTCOME MEASURES Expression of STAT3, pSTAT3, SOCS3, COL1A1, and TGFb3. RESULTS We observed that IL6 increased pSTAT3 as well as collagen1A1 in uterine leiomyoma cells. Direct activation of the JAK/STAT3 pathway increased collagen1A1 production in leiomyoma cells, whereas inhibition of the pathway significantly decreased collagen1A1 production. We further observed that modulation of the JAK/STAT3 pathway also increased the expression of TGFβ3 protein. Leiomyoma cells exposed to TGFβ3 demonstrated a significant decrease in pSTAT3 protein. Myometrial cells demonstrated a less sensitive response to STAT3 modulation and collagen production. CONCLUSION Cross-talk between the TGFβ pathway and JAK/STAT3 pathway contributes to the fibrotic nature of uterine leiomyomas.

Abstract
CONTEXT Uterine leiomyomata (fibroids) are prevalent sex hormone‒dependent tumors with an altered response to mechanical stress. Ulipristal acetate, a selective progesterone receptor (PR) modulator, significantly reduces fibroid size in patients. However, PR signaling in fibroids and its relationship to mechanical signaling are incompletely understood. OBJECTIVE Our prior studies revealed that A-kinase anchoring protein 13 (AKAP13) was overexpressed in fibroids and contributed to altered mechanotransduction in fibroids. Because AKAP13 augmented nuclear receptor signaling in other tissues, we sought to determine whether AKAP13 might influence PR signaling in fibroids. METHODS AND RESULTS Fibroid samples from patients treated with ulipristal acetate or placebo were examined for AKAP13 expression by using immunohistochemistry. In immortalized uterine fibroid cell lines and COS-7 cells, we observed that AKAP13 increased ligand-dependent PR activation of luciferase reporters and endogenous progesterone-responsive genes for PR-B but not PR-A. Inhibition of ERK reduced activation of PR-dependent signaling by AKAP13, but inhibition of p38 MAPK had no effect. In addition, glutathione S-transferase‒binding assays revealed that AKAP13 was bound to PR-B through its carboxyl terminus. CONCLUSION These data suggest an intersection of mechanical signaling and PR signaling involving AKAP13 through ERK. Further elucidation of the integration of mechanical and hormonal signaling pathways in fibroids may provide insight into fibroid development and suggest new therapeutic strategies for treatment.

Abstract
Uterine fibroids (UFs) are the most common benign tumors of the female genital tract. The incidence of UFs has been estimated at 25⁻80% depending on selected population. The pathophysiology of UFs remains poorly understood. The transformation of smooth muscle cells of the uterus into abnormal, immortal cells, capable of clonal division, is the main component of all pathways leading to UF tumor formation and tumor necrosis factor α (TNF-α) is believed to be one of the key factors in this field. TNF-α is a cell signaling protein involved in systemic inflammation and is one of the cytokines responsible for the acute phase reaction. This publication presents current data about the role of tumor necrosis factor α in the biology of UFs and the related symptoms. TNF-α is an extremely important cytokine associated with the biology of UFs, UF-related symptoms and complaints. Its concentration has been proven to be elevated in women with clinically symptomatic UFs. The presented data suggest the presence of an "inflammation-like" state in women with UFs where TNF-α is a potent inflammation inducer. The origin of numerous symptoms reported by women with UFs can be traced back to the TNF-α influence. Nevertheless, our knowledge on this subject remains limited and TNF-α dependent pathways in UF pathophysiology should be investigated further.

Abstract
CONTEXT Ulipristal acetate (UPA), a selective progesterone receptor modulator, clinically reduces uterine myoma size in 80% of cases. However, the molecular mechanism of action is still poorly understood, as is the reason why 20% of myomas do not respond to treatment. OBJECTIVE To elucidate whether matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are associated with myoma volume shrinkage after UPA therapy. DESIGN Prospective study. SETTING Academic research unit of a university hospital. PATIENTS Uterine biopsies were obtained from 59 patients with symptomatic myomas undergoing myomectomy, 45 of whom were treated preoperatively with either one or greater than or equal to two, 3-month courses of UPA and 14 not given any hormone therapy to serve as controls. Myoma volume was individually monitored during UPA therapy to determine any substantial clinical response (defined as a reduction in volume of >25%). Three groups were established based on the response to treatment: responsive (R) after one course (n = 12); R after two to four courses (n = 15); and nonresponsive (NR; n = 18). INTERVENTIONS UPA treatment given as preoperative management for symptomatic myomas. MAIN OUTCOME MEASURES MMP and TIMP expression assessed by zymography and immunohistochemistry. RESULTS Compared with controls and NR myomas, responders showed significantly higher expression levels for MMP-1 (P < 0.0001) and MMP-2 (P = 0.009) and significantly lower expression levels for TIMP-1 (P = 0.040). CONCLUSIONS The correlation found between MMP expression and volume fold change supports the notion that MMPs play a key role in UPA-induced myoma shrinkage.

Abstract
A deeper understanding of the pathways that drive uterine leiomyoma (ULM) growth and survival requires model systems that more closely mimic the in vivo tumors. This would provide new insights into developing effective therapeutic strategies for these common benign tumors of childbearing-aged women. In this study, we examined the role of BCL-2 in mediating ULM survival in the context of increased protein kinase B (AKT) and oxidative stress using a three-dimensional (3D), spheroid-based model that more closely resembles the native ULM tumor microenvironment. Human primary cells from matched myometrium (MM) and ULM tissues were used to establish spheroid cultures in vitro. Histological and immunohistochemical methods were used to assess the spheroid architecture and characteristics. Viability assays for 3D cultures were used to evaluate their response to BH3 mimetics and the superoxide inducer, paraquat (PQ). Primary MM and ULM cells formed spheroids in culture. Notably, ULM spheroids exhibited low proliferation, increased oxidative stress, and secretion of interstitial collagen. Knockdown studies revealed that AKT sustained BCL-2 expression in ULM. The targeting of BCL-2 with BH3 mimetics effectively reduced viability and induced apoptosis in a subset of ULM spheroids. ULM spheroids that did not respond to BH3 mimetics alone responded to combination treatment with PQ. In conclusion, BCL-2 mediates AKT survival of ULM, providing compelling evidence for further evaluation of BH3 mimetics for ULM treatment. ULM spheroids recapitulated intrinsic features of the native ULM tumor microenvironment and can be used as a model for preclinical testing of potential therapeutic options for ULM.

Abstract
Uterine fibroids (myomas or leiomyomas) are common benign tumors of reproductive aged women. Fibroids are clinically apparent in 20-50% of women, and cause abnormal uterine bleeding, abdominal pain and discomfort, pregnancy complications and infertility. Unfortunately, limited numbers of medical treatment are available but no effective preventive strategies exist. Moreover, the benefits of medical treatments are tempered by lack of efficacy or serious adverse side effects. Fibrosis has recently been recognized as a key pathological event in leiomyoma development and growth. It is defined by the excessive deposition of extracellular matrix (ECM). ECM plays important role in making bulk structure of leiomyoma, and ECM-rich rigid structure is believed to be a cause of abnormal bleeding and pelvic pain/pressure. Dietary phytochemicals are known to regulate fibrotic process in different biological systems, and being considered as potential tool to manage human health. At present, very few dietary phytochemicals have been studied in uterine leiomyoma, and they are mostly known for their antiproliferative effects. Therefore, in this review, our aim was to introduce some dietary phytochemicals that could target fibrotic processes in leiomyoma. Thus, this review could serve as useful resource to develop antifibrotic drugs for possible prevention and treatment of uterine fibroids.

Abstract
Objective To estimate the phenotypic characterization of fibrotic process in adenomyosis occurring at the inner or the outer myometrium. Methods Eight cases of adenomyosis occurring at the inner myometrium (Subtype I) and 10 cases of adenomyosis occurring at the outer myometrium (Subtype II), and 10 normal counterparts were used in this study. A immunohistochemical study for smooth muscle cells (SMCs) was performed using cytoskeletal proteins, Type I and III collagen, TGF-β and its signaling molecules. Results An increased expression of Type I collagen was observed in the extracellular matrix of adenomyotic foci. In normal uteri, immunostaining of SMC differentiation marker proteins (Desmin, Smoothelin, Myosin heavy chain (MHC)) were absent or only found in low numbers at the inner myometrium, while all of these marker proteins were clearly stained at the outer myometrium. In both types of adenomyotic foci, Desmin, Smoothelin, and MHC commonly showed a negative staining at the adjacent area to the glands. A significant staining of Non-muscle myosin IIB, TGF-β, and phosphorylated TGF-β type I receptors were found only at the SMCs of Subtype II adenomyosis. The Smad3/2 ratio of Subtype II adenomyosis was significantly higher than that of Subtype I. Conclusions The inner myometrium of normal uteri was composed of undifferentiated phenotypes of SMCs, while the outer myometrium was composed of terminally differentiated SMCs. Various fibrotic processes have been suggested in the development of uterine adenomyosis. Distinct expression patterns of fibrosis related proteins have been shown to be implicated with differences in the subtypes of adenomyosis.

Abstract
In a prior randomized controlled study, patients treated with ulipristal acetate (UPA) or placebo for 3 months had a decrease in leiomyoma size. A total of 10 patients' tissue samples (5 placebo and 5 treated with 10 mg/d UPA) that underwent hysterectomy and tissue preservation were identified from this study. Quantitative real-time reverse transcriptase polymerase chain reaction and Western blotting were used to assess fold gene and protein expression of extracellular membrane (ECM) proteins: collagen 1A (COL1A), fibronectin (FN1), and versican (VCAN) of the samples. Confirmatory immunohistochemical analysis was performed. Changes in total matrix collagen were examined using Masson trichrome staining. Multiplex measurement of the matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases was performed. Compared to placebo-treated surgical specimens, 80% of the treated specimens showed decrease in VCAN protein, 60% showed decrease in FN1, but no consistent alteration in COL1A. This effect was also supported by immunohistochemistry where leiomyoma surgical specimens demonstrated decreased amount of FN1 and VCAN on UPA treatment. Increased MMP2 and decreased MMP9 in treated patient leiomyomas indicate both degradation of the matrix and inhibition of the pathway involved in matrix production. Treatment with UPA decreased fibroid volume in placebo-controlled, randomized trials. Treatment with UPA decreased gene expression and protein production in leiomyoma tissue, suggesting both an impact on water content and ECM protein concentration as a mechanism of ulipristal-mediated decrease in leiomyoma size.

Abstract
Uterine fibroids, also known as uterine leiomyoma (UL), are monoclonal tumors of the smooth muscle tissue layer (myometrium) of the uterus. Although ULs are considered benign, uterine fibroids are the source of major quality-of-life issues for approximately 25% of all women, who suffer from clinically significant symptoms of UL. Despite the prevalence of UL, there is no treatment option for UL which is long term, cost-effective, and leaves fertility intact. The lack of understanding about the etiology of UL contributes to the scarcity of medical therapies available. Studies have identified an important role for sex steroid hormones in the pathogenesis of UL, and have driven the use of hormonal treatment for fibroids, with mixed results. Dysregulation of cell signaling pathways, miRNA expression, and cytogenetic abnormalities have also been implicated in UL etiology. Recent discoveries on the etiology of UL and the development of relevant genetically modified rodent models of UL have started to revitalize UL research. This review outlines the major characteristics of fibroids; major contributors to UL etiology, including steroid hormones; and available preclinical animal models for UL.

Abstract
Long-term exposure to excess estrogen increases the risk of breast cancer and type 1 endometrial cancer. Most of the estrogen in premenopausal women is synthesized by the ovaries, while extraovarian subcutaneous adipose tissue is the predominant tissue source of estrogen after menopause. Estrogen and its metabolites can cause hyperproliferation and neoplastic transformation of breast and endometrial cells via increased proliferation and DNA damage. Several genetically modified mouse models have been generated to help understand the physiological and pathophysiological roles of aromatase and estrogen in the normal breast and in the development of breast cancers. Aromatase, the key enzyme for estrogen production, is comprised of at least ten partially tissue-selective and alternatively used promoters. These promoters are regulated by distinct signaling pathways to control aromatase expression and estrogen formation via recruitment of various transcription factors to their cis-regulatory elements. A shift in aromatase promoter use from I.4 to I.3/II is responsible for the excess estrogen production seen in fibroblasts surrounding malignant epithelial cells in breast cancers. Targeting these distinct pathways and/or transcription factors to modify aromatase activity may lead to the development of novel therapeutic remedies that inhibit estrogen production in a tissue-specific manner.

Abstract
OBJECTIVE To characterize the efficacy of mifepristone treatment on extracellular matrix (ECM) production in leiomyomas. DESIGN Laboratory study. SETTING University research laboratory. PATIENT(S) None. INTERVENTION(S) Treatment of human immortalized two-dimensional (2D) and three-dimensional (3D) leiomyoma and myometrial cells with mifepristone and the progestin promegestone (R5020). MAIN OUTCOME MEASURE(S) Expression of COL1A1, fibronectin, versican variant V0, and dermatopontin in treated leiomyoma cells by Western blot analysis and confirmatory immunohistochemistry staining of treated 3D cultures. RESULT(S) Treatment with progestin stimulated production of COL1A1, fibronectin, versican, and dermatopontin. Mifepristone treatment inhibited protein production of these genes, most notably with versican expression. Combination treatment with both the agonist and antagonist further inhibited protein expression of these genes. Immunohistochemistry performed on 3D cultures demonstrated generalized inhibition of ECM protein concentration. CONCLUSION(S) Our study demonstrated that the progesterone agonist R5020 directly stimulated extracellular matrix components COL1A1, fibronectin, versican, and dermatopontin production in human leiomyoma cells. Progesterone antagonist mifepristone decreased protein production of these genes to levels comparable with untreated leiomyoma cells.

Abstract
Uterine leiomyomas (fibroids) are the most prevalent medical problem of the female reproductive tract, but there are few non-surgical treatment options. Although many advances in the understanding of the molecular components of these tumors have occurred over the past five years, an effective pharmaceutical approach remains elusive. Further, there is currently no clinical method to distinguish a benign uterine leiomyoma from a malignant leiomyosarcoma prior to treatment, a pressing need given concerns about the use of the power morcellator for minimally invasive surgery. This paper reviews current studies regarding the molecular biology of uterine fibroids, discusses non-surgical approaches and suggests new cutting-edge therapeutic and diagnostic approaches.
