Abstract
Uterine fibroids (UF) are common benign tumors in women. The course of UF is associated with troubling symptoms and the development of infertility and pregnancy pathology. Surgical treatment even implies hysterectomy, while pharmacological interventions are modestly effective. Classically, hypoxic metabolism is considered a hallmark of malignant tumor. However, the role of hypoxia-induced factor (HIF) is significant in benign tumors as well. Herein, we briefly review the basic biology of HIF-family proteins, outlining their possible roles in UF. Apart from theoretical justifications, we summarized 15 studies reporting increased expression of HIFs and downstream factors in UF samples. Altogether, data suggest that increased expression of the HIF-protein and altered expression of its dependent genes are presumed to be the factors leading to UF development. Thus, even without being a malignant tumor, UF is characterized by the strong involvement of HIF. This novel insight may give rise to further research in the direction of finding new prognostic markers and effective medicines against UF.

Abstract
OBJECTIVE Obesity and its consequences are among the biggest challenges facing the healthcare system. Uterine leiomyomas are the most common gynecologic tumors. The risk of leiomyoma increases with obesity, but the underlying mechanisms of this association remain unclear. The aim of the present study to determine the cellular and molecular mechanisms by which adipocyte contributes to both leiomyoma tumor initiation and promotion. METHODS Primary myometrium and leiomyoma cells were isolated from patients who underwent a hysterectomy or myomectomy. Pro-inflammatory, fibrotic, and angiogenic factors were measured using a multiplex cytokine array in human primary and immortalized myometrial and leiomyoma cells cocultured with human adipocyte (SW872) cells, or in animal ELT3 leiomyoma cells cocultured with 3 T3-L1 adipocytes. The free fatty acids (FFAs) and fatty acid-binding protein 4 (FABP4) levels were measured using immunofluorescence assays. Other protein abundances were determined using western blots. The expression levels of TNF-α, MCP-1, phospho-NF-κB, TGFβ3 and VEGF-A in lean and obese in different leiomyoma patients were determined by immunofluorescence staining. RESULTS Adipocytes promote inflammation, fibrosis, and angiogenesis in uterine leiomyoma cells by upregulating associated factors, such as IL-1β, TNF-α, MCP-1, GM-CSF, TGF-βs, PLGF, VEGF, HB-EGF, G-CSF and FGF2. Coculture led to the transfer of FFAs and FABP4 from adipocytes to leiomyoma cells, suggesting that adipocytes may modulate metabolic activity in these tumor cells. Increased levels of FFA and FABP4 expressions were detected in obese leiomyoma tissue compared to lean. The adipocyte-leiomyoma cell interaction increased the phospho-NF-κB level, which plays a key role in inflammation, restructuring metabolic pathways, and angiogenesis. Obese leiomyoma patients expressed a higher amount of TNF-α, MCP-1, phospho-NF-κB, TGFβ3 and VEGF-A than lean leiomyoma patients, consistent with in vitro findings. Furthermore, we found that adipocyte secretory factors enhance leiomyoma cell proliferation by increasing PCNA abundance. Finally, the inhibition of the inflammatory factors TNF-α, MCP-1, and NF-κB abrogated the adipocyte coculture-induced proliferation of leiomyoma cells. CONCLUSIONS Adipocytes release inflammatory, fibrotic, and angiogenic factors, along with FFAs, which contribute to a tumor-friendly microenvironment that may promote leiomyoma growth and can represent a new target for leiomyoma prevention and treatment.

Abstract
Uterine fibroids (UF) represent an immense health burden throughout the world. Obesity is considered one of the risk factors for UF development; however, the underlying mechanisms remain largely unexplored. We investigated the effect of obesity on fibroblast activation and its association with inflammation, autophagy dysfunction, and oxidative stress in UF patients. Thirty-five pre-menopausal UF patients were included in this study and classified into non-obese group (BM1 ≤ 30 kg/m2, n = 15) and obese group (BMI > 30 kg/m2, n = 20). Tissue samples were collected from fibroids and adjacent normal myometrium. Our results showed increased expression of fibroblast activation protein (FAP) together with markers of autophagy, inflammation, and oxidative stress in UF patients, which were all more markedly upregulated in obese compared to non-obese patients. In addition, BMI was significantly positive correlated with FAP and autophagy markers. In conclusion, the results of the present study suggest that obesity-associated autophagy dysregulation together with increased FAP expression may increase the risk of UFs in obese women.

Abstract
Uterine fibroids (UFs) are the most prevalent gynecologic neoplasm, affecting 70-80% of women over their lifespan. Although UFs are benign they can become life-threatening and require invasive surgeries such as myomectomy and hysterectomy. Notwithstanding the significant negative influence UFs have on female reproductive health, very little is known about early events that initiate tumor development. Several risk factors for UFs have been identified including vitamin D deficiency, inflammation, DNA repair deficiency, and environmental exposures to endocrine-disrupting chemicals (EDCs). EDCs have come under scrutiny recently due to their role in UF development. Epidemiologic studies have found an association between increased risk for early UF diagnosis and in utero EDC exposure. Environmental exposure to EDCs during uterine development increases UF incidence in a UF animal model. Notably, several studies demonstrated that abnormal myometrial stem cells (MMSCs) are the cell origin for UFs development. Our recent studies demonstrated that early-life EDC exposure reprogrammed the MMSCs toward a pro-fibroid landscape and altered the DNA repair and inflammation pathways. Notably, Vitamin D3 (VITD3) as a natural compound shrank the UF growth concomitantly with the reversion of several abnormal biological pathways and ameliorated the developmental exposure-induced DNA damage and pro-inflammation pathway in primed MMSCs. This review highlights and emphasizes the importance of multiple pathway interactions in the context of hypovitaminosis D at the MMSCs level and provides proof-of-concept information that can help develop a safe, long-term, durable, and non-surgical therapeutic option for UFs.

Abstract
INTRODUCTION Many women of premenopausal age suffer from uterine leiomyomas, which are benign tumors of the uterus. Despite the high prevalence of uterine leiomyomas underlying pathogenesis mechanisms are not fully elucidated. Early data showed a positive correlation between increased levels of adipose tissue and leiomyomas prevalence. Adipose tissue cells-adipocytes can play a potential role in leiomyomas formation by producing and secreting adipokines. AIM The aim of this study is to summarize the current knowledge on the potential relation between adipokines and leiomyomas basing on current data analyze, and justify future research directions. METHODOLOGY This review is based on pertinent articles searched using PubMed, encompassing all available literature. The key search words were as follows: adipokines, leiomyoma, TNFα, leptin, adiponectin, visfatin, resistin, omentin, lipocalin, apelin, adipsin, chemerin. Time was not an exclusion criterium due to few available studies on this subject. SUMMARY The results of the studies are inconclusive, but the vast majority indicates a significant connection between the adipokines and the leiomyomas. According to the majority of studies, TNFα contributes to the development of leiomyomas by inhibiting apoptosis, increasing migration of leiomyomas, and increasing fibrosis of leiomyomas. Most of the studies on the effects of leptin also indicate the relation between leptin and leiomyomas development. In the case of adiponectin released from mast cells' granularity, it is possible that adiponectin increases angiogenesis in leiomyomas. Under physiological conditions, adiponectin has the potential to inhibit the development of leiomyomas. The authors suggested that adiponectin affects leiomyomas via an insulin-dependent pathway or via an estrogen-dependent pathway. Most probably leptin contributes to the formation of myomas and adiponectin prevents this. More research is needed to understand better the influence of these molecules on the pathogenesis of leiomyomas.

Abstract
There has been a significant annual increase in the number of cases of uterine leiomyomas or fibroids (UF) among women of all races and ages across the world. A fortune is usually spent by the healthcare sector for fibroid-related treatments and management. Molecular studies have established the higher mutational heterogeneity in UF as compared to normal myometrial cells. The contribution of DNA damage and defects in repair responses further increases the mutational burden on the cells. This in turn leads to genetic instability, associated with cancer risk and other adverse reproductive health outcomes. Such and many more growing bodies of literature have highlighted the genetic/molecular, biochemical and clinical aspects of UF; none the less there appear to be a lacuna bridging the bench to bed gap in addressing and preventing this disease. Presented here is an exhaustive review of not only the molecular mechanisms underlying the predisposition to the disease but also possible strategies to effectively diagnose, prevent, manage, and treat this disease.

Abstract
BACKGROUND Both European and American trials showed superior effect of ulipristal acetate (UPA) to placebo. However, the latter, which included black patients with known higher vitaminD3 deficiency risk, showed lower rate of amenorrhea responders and insignificant uterine fibroid (UF) size reduction. Our objective is to investigate whether adding vitamin D3 to UPA can enhance UPA potency on UF phenotype in vitro. METHODS We screened the antiproliferative effect of different (UPA/vitaminD3) combinations on UF cell proliferation using dimethylthiazolyl diphenyltetrazolium bromide assay. Cells then were treated with UPA 100 nM in the presence or absence of vitamin D3 100 nM, and expression level of several markers related to proliferation, apoptosis, fibrosis, inflammation, and angiogenesis was measured on RNA or at protein level using quantitative real-time polymerase chain reaction, Western blot, immunofluorescence, or multiplex enzyme-linked immunosorbent assay techniques. RESULTS Significant dose- and time-dependent growth inhibitory effects of UPA/vitamin D3 combinations were observed compared to untreated cells at 2 and 4 days (P < .05). Importantly, vitamin D3/UPA combination significantly reduced cell proliferation as compared to UPA at 2, 4, 6, and 8 days (P < .05). Combination treatment significantly decreased protein expression of proliferation markers Ki-67, PCNA, and CyclinD1 by more than 50% compared to UPA (P < .05) along with a significant increase in apoptosis induction. Combination treatment resulted in a 2-fold decrease in protein levels of extracellular matrix markers collagen-1 and fibronectin besides pro-fibrogenic cytokine transforming growth factor β3 (P < .05). Moreover, it significantly decreased the production of pro-inflammatory cytokines interleukins 6, 8, 1α, and 1β compared to UPA (P < .05). CONCLUSION Combination of vitamin D3 with UPA exhibits additional and orchestrated anti-UF effects, therefore might offer a more favorable clinical option.

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
Uterine fibroids (UFs) are one of the most common pathologies of the female genital tract. The incidence of UFs has been estimated at 25-80%. Tumor necrosis factor (TNF)-α is a cell-signaling protein involved in systemic inflammation and is one of the cytokines responsible for the acute phase reaction. The aim of the study was to evaluate the impact of clinically symptomatic UFs on TNF-α serum levels. A total of 149 Caucasian women were included: 85 patients admitted for surgery due to clinically symptomatic UFs (n = 85; study group) and 64 age-matched UF-free controls (n = 64). TNF-α serum concentrations between the groups were compared. Receiver operating characteristic (ROC) curves were also used as a statistical model to evaluate TNF-α as a marker for UFs. Mean TNF-α serum concentration in the study group was 0.34 ± 0.14 pg/mL; (in half of the subjects, the level did not exceed 0.39 pg/mL. Mean TNF-α serum concentration in the control group was 0.17 ± 0.09 pg/mL; in half of the subjects, the level did not exceed 0.14 pg/mL. The difference was statistically significant. Using the area under the ROC curve, we found that TNF-α serum concentration of 0.34 pg/mL can be used as a predictor for UFs in selected populations. In our study, we confirmed higher TNF-α serum concentrations in women with clinically symptomatic UFs.

Abstract
BACKGROUND The risk of preterm birth may increase in the presence of uterine leiomyomas during pregnancy. Whether myomectomy abrogates this risk has never been studied. OBJECTIVE Our aim was to evaluate the association between the presence of uterine leiomyomas during pregnancy and preterm birth and, if an association exists, to evaluate its persistence in case of a history of myomectomy. STUDY DESIGN This exposed/unexposed monocentric retrospective cohort study included all women with singleton pregnancies delivering >22 weeks in a tertiary university hospital maternity unit from January 2011 through September 2015. Women with a leiomyomatous uterus were compared to women with no myomas. Women in the leiomyomatous uterus group were women with uterine leiomyoma(s) during pregnancy (≥1 leiomyoma, measuring ≥20 mm or multiple leiomyomas whatever the size) seen on at least 1 obstetric ultrasound without history of myomectomy, or women with a history of myomectomy (removal of ≥1 leiomyoma, measuring ≥20 mm or multiple leiomyomas whatever the size) by hysteroscopy, laparoscopy, or laparotomy with or without persistent leiomyomas. The association between leiomyomatous uterus and preterm birth was assessed through univariate and multivariable logistic regression. RESULTS Among the 19,866 women in the cohort, 301 (1.5%) had a leiomyomatous uterus (154 unoperated women and 147 operated women). The rate of premature delivery was 12.0% in the leiomyomatous uterus group and 8.4% in the nonleiomyomatous uterus group. After adjusting for the risk factors for preterm birth, leiomyomatous uterus was significantly associated with preterm birth (adjusted odds ratio, 2.5; 95% confidence interval, 1.7-3.7). This association was significant for unoperated women (adjusted odds ratio, 2.7; 95% confidence interval, 1.6-4.6) as well as operated women (adjusted odds ratio, 2.3; 95% confidence interval, 1.3-3.9) when compared to the nonleiomyomatous uterus group. CONCLUSION Uterine leiomyomas are associated with preterm birth and this association persists after myomectomy.

Abstract
We analyzed cytokine profile in blood serum of patients with uterine myoma and revealed significantly reduced level of IFNγ and a tendency towards a decrease in the levels of IL-1β and TNFα; the levels of IL-6, IL-8, and IL-12p70 did not differ from those in healthy women. The drop in the concentrations of factors responsible for inflammation and angiogenesis in tissues are unfavorable for proliferation and differentiation of the uterine tissues.

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.

Differential expression of tumor necrosis factor α, interleukin 1β, nuclear factor κB in nasal mucosa among chronic rhinosinusitis patients with and without polyps. Postepy Dermatol Alergol 2017; 34:199-206. [PMID: 28670247 PMCID: PMC5471375 DOI: 10.5114/ada.2017.67842] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2016] [Accepted: 11/14/2016] [Indexed: 01/19/2023] Open
Abstract
INTRODUCTION The pathogenesis of nasal polyps is still not fully understood. AIM To analyze the topography and intensity of interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), cyclooxygenase 2 (COX-2), nitric oxide synthase 2 (NOS-2), and nuclear factor-κB (NF-κB) expressions in eosinophilic and neutrophilic polyps and in normal nasal mucosa. MATERIAL AND METHODS The study included specimens from 20 patients with eosinophilic polyps (more than 10% of eosinophils in inflammatory infiltrate), 20 individuals with neutrophilic polyps (predominance of neutrophils and less than 10% of eosinophils), and samples of normal nasal mucosa from 10 controls. The expressions of studied proteins in vascular endothelial cells, epithelial, stromal and glandular cells were determined immunohistochemically with specific monoclonal antibodies. RESULTS Irrespective of the cellular type, the intensity of expressions in eosinophilic and neutrophilic polyps was significantly higher than in the normal mucosa. Eosinophilic polyps were characterized by stronger expressions of TNF-α (in all cellular types), IL-1β (in endothelial, glandular and epithelial cells), NF-κB (in stromal and epithelial cells), COX-2 (in glandular and stromal cells), and NOS-2 (in endothelial and stromal cells). In contrast, neutrophilic polyps showed significantly stronger expressions of COX-2 (in epithelial and endothelial cells) and NOS-2 (in glandular and epithelial cells). In both phenotypes, the strongest expressions of all studied markers were documented in vascular endothelial cells. CONCLUSIONS Inflammatory markers are involved in pathogenesis of both eosinophilic and neutrophilic polyps. Endothelial defects can play an important role in the development of nasal polyps.

Abstract
Uterine leiomyoma is the most common female reproductive tract benign tumor. Little is known about protein composition and changes in the leiomyoma interstitial fluid (IF). The present study focused on changes in protein abundance in the IF of leiomyoma. Leiomyoma IFs and adjacent myometrial IFs were obtained and analyzed by two-dimensional electrophoresis (2-DE) coupled with mass spectrometry and western blotting for 2-DE data validation. A total of 25 unique proteins were observed to change significantly (P<0.05). Of these proteins with different abundance, 22 had not been previously identified in leiomyoma IF. In silico analysis predicted that three of these proteins were secreted via classical mechanisms, while 22 were secreted via non-classical mechanisms. Ingenuity Pathway Analysis identified 17 proteins associated with cellular migration and proliferation. Among these, phosphoglycerate mutase 1 had not been previously associated with leiomyoma. The abundance of seven proteins was further validated by western blotting. A comparative proteomic approach identified a number of proteins associated with cellular migration and proliferation, with changes in abundance in IF likely to be involved in tumor development. Further studies will be required to investigate the role of these proteins in leiomyoma IF and their possible association with tumor development and growth.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Uterine fibroid (myoma) is one of the most common diseases in women. Although there are several studies on the efficacy of Chinese herbs, there is a lack of large-scale survey on the use of traditional Chinese medicine (TCM) for the treatment of uterine fibroid. This study aimed to investigate the utilization of Chinese herbal products for patients with uterine fibroid, prescribed by licensed TCM doctors in Taiwan. MATERIALS AND METHODS A random sample comprised of one million individuals with newly diagnosed uterine fibroid between 2002 and 2010 from the Taiwanese National Health Insurance Research Database was analyzed. Demographic characteristics, TCM usage, the frequency as well as average daily dose of Chinese herbal formulas and the single herbs prescribed for patients with uterine fibroid, were analyzed. RESULTS Overall, 35,786 newly diagnosed subjects with uterine fibroid were included. Majority of these patients (87.1%; n=31,161) had visited TCM clinics. Among them, 61.8% of their visits used Chinese herbal remedies. Patients less than 45 years of age tended to use TCM more frequently than elder patients. Gui-Zhi-Fu-Ling-Wan (Cinnamon Twig and Poria Pill) was the most frequently prescribed Chinese herbal formula, while San-Leng (Rhizoma Sparganii) was the most commonly prescribed single herb. CONCLUSIONS Our study identified the characteristics and prescription patterns of TCM for patients with uterine fibroid in Taiwan. Further basic mechanistic studies and clinical trials are needed to confirm the therapeutic effects and mechanisms.

Abstract
BACKGROUND Uterine leiomyomas (fibroids) are highly prevalent benign smooth muscle tumors of the uterus. In the USA, the lifetime risk for women developing uterine leiomyomas is estimated as up to 75%. Except for hysterectomy, most therapies or treatments often provide only partial or temporary relief and are not successful in every patient. There is a clear racial disparity in the disease; African-American women are estimated to be three times more likely to develop uterine leiomyomas and generally develop more severe symptoms. There is also familial clustering between first-degree relatives and twins, and multiple inherited syndromes in which fibroid development occurs. Leiomyomas have been described as clonal and hormonally regulated, but despite the healthcare burden imposed by the disease, the etiology of uterine leiomyomas remains largely unknown. The mechanisms involved in their growth are also essentially unknown, which has contributed to the slow progress in development of effective treatment options. METHODS A comprehensive PubMed search for and critical assessment of articles related to the epidemiological, biological and genetic clues for uterine leiomyoma development was performed. The individual functions of some of the best candidate genes are explained to provide more insight into their biological function and to interconnect and organize genes and pathways in one overarching figure that represents the current state of knowledge about uterine leiomyoma development and growth. RESULTS In this review, the widely recognized roles of estrogen and progesterone in uterine leiomyoma pathobiology on the basis of clinical and experimental data are presented. This is followed by fundamental aspects and concepts including the possible cellular origin of uterine fibroids. The central themes in the subsequent parts are cytogenetic aberrations in leiomyomas and the racial/ethnic disparities in uterine fibroid biology. Then, the attributes of various in vitro and in vivo, human syndrome, rodent xenograft, naturally mutant, and genetically modified models used to study possible molecular mechanisms of leiomyoma development and growth are described. Particular emphasis is placed on known links to fibrosis, hypertrophy, and hyperplasia and genes that are potentially important in these processes. CONCLUSIONS Menstrual cycle-related injury and repair and coinciding hormonal cycling appears to affect myometrial stem cells that, at a certain stage of fibroid development, often obtain cytogenetic aberrations and mutations of Mediator complex subunit 12 (MED12). Mammalian target of rapamycin (mTOR), a master regulator of proliferation, is activated in many of these tumors, possibly by mechanisms that are similar to some human fibrosis syndromes and/or by mutation of upstream tumor suppressor genes. Animal models of the disease support some of these dysregulated pathways in fibroid etiology or pathogenesis, but none are definitive. All of this suggests that there are likely several key mechanisms involved in the disease that, in addition to increasing the complexity of uterine fibroid pathobiology, offer possible approaches for patient-specific therapies. A final model that incorporates many of these reported mechanisms is presented with a discussion of their implications for leiomyoma clinical practice.

Cathepsin B in human myometrium and in uterine leiomyomas at various stages of tumour growth. Eur J Obstet Gynecol Reprod Biol 2015; 185:140-4. [PMID: 25577554 DOI: 10.1016/j.ejogrb.2014.12.020] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2014] [Revised: 12/11/2014] [Accepted: 12/18/2014] [Indexed: 01/23/2023]
Abstract
OBJECTIVE Cathepsin B is a major cysteine protease involved in the degradation of extracellular matrix proteins, as well as in the activation of precursor forms of other proteases and in release of matrix-bound growth factors. We assessed the expression and activity of cathepsin B, and the inhibitory effect of cysteine protease inhibitors in human myometrium and uterine leiomyomas at various stages of tumour growth. STUDY DESIGN Studies were performed on human myometrium collected from 12 patients and on uterine leiomyomas of various weights: small (less than or equal to 25 g, taken from 10 patients) and large (more than or equal to 100 g, obtained from 13 patients). Tissue extracts were assayed for cathepsin B activity and for inhibitory effect of cysteine protease inhibitors against papain using fluorogenic substrates, and calculated per DNA content. Statistical analysis was performed by Kruskal-Wallis analysis of variance followed by Dunn's post hoc tests. The enzyme expression was evaluated by SDS/polyacrylamide gel electrophoresis followed by Western immunoblotting. RESULTS In all the investigated tissues cathepsin B exists mainly in a fully processed double-chain form. The enzyme activity and expression were similar in control myometrium and in small leiomyomas. However, they distinctly increased during tumour growth. The effect of cysteine protease inhibitors was comparable in all the tissues examined. CONCLUSION These data suggest that the enhanced activity and expression of cathepsin B but not the action of cysteine protease inhibitors contribute to an increased remodelling of extracellular matrix and bioavailability of various growth factors, which favour leiomyoma growth.

Abstract
The objective of this work was use of silybin nanoparticles in treatment of ulcerative colitis (UC). Eudragit RL PO nanoparticles loaded with silybin were produced using solvent-evaporation emulsification technique. Then, they were coated by Eudragit FS30D. Drug release was studied in different physiological environments. Colitis was induced by 4% of acetic acid in rats which received freeze-dried nanoparticles of silybin (75 mg/kg/day), dexamethasone (1 mg/kg/day), blank nanoparticles and normal saline orally for 5 days. Then macroscopic, histopathological evaluation and biochemical analysis, including myeloperoxidase (MPO) activity, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels in colon tissues were determined using enzyme-linked immunosorbent assay (ELISA) kits. Macroscopic and histopathological scores were improved by the optimised nanoparticles. The optimised nanoparticles had a particle size of 109 ± 6 nm, zeta potential of 15.4 ± 2 mV, loading efficiency of 98.3 ± 12% and release efficiency of 40.8 ± 5.5% at 24 h. TNF-α, IL-6 and MPO activity were reduced significantly by nanoparticles compared to control group (p < 0.05).
