Abstract
Endometrial cancer (EC) is an increasing health concern, with its growth driven by an angiogenic switch that occurs early in cancer development. Our study used publicly available datasets to examine the expression of angiogenesis-related genes and proteins in EC tissues, and compared them with adjacent control tissues. We identified nine genes with significant differential expression and selected six additional antiangiogenic genes from prior research for validation on EC tissue in a cohort of 36 EC patients. Using machine learning, we built a prognostic model for EC, combining our data with The Cancer Genome Atlas (TCGA). Our results revealed a significant up-regulation of IL8 and LEP and down-regulation of eleven other genes in EC tissues. These genes showed differential expression in the early stages and lower grades of EC, and in patients without deep myometrial or lymphovascular invasion. Gene co-expressions were stronger in EC tissues, particularly those with lymphovascular invasion. We also found more extensive angiogenesis-related gene involvement in postmenopausal women. In conclusion, our findings suggest that angiogenesis in EC is predominantly driven by decreased antiangiogenic factor expression, particularly in EC with less favourable prognostic features. Our machine learning model effectively stratified EC based on gene expression, distinguishing between low and high-grade cases.

Exp Ther Med 2022; 25:76. [PMID: 36684658 PMCID: PMC9842939 DOI: 10.3892/etm.2022.11775] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Accepted: 11/10/2022] [Indexed: 12/24/2022] Open
Abstract
The hypothalamic peptide gonadotropin inhibitory hormone (GnIH) is a relatively novel hypothalamic neuropeptide, identified in 2000. It can influence the hypothalamic-pituitary-gonadal axis and reproductive function through various neuroendocrine systems. The present study aimed to explore the effects and potential underlying molecular mechanism of RFamide-related peptide-3 (RFRP-3) injection on the uterine fluid protein profile of ovariectomized estrogen-primed (OEP) rats using proteomics. In addition, the possible effects of RFRP-3 on the viability and apoptosis of the human endometrial cancer cell line HEC-1A and associated molecular mechanism were investigated. The OEP rat model was established through injection with GnIH/RFRP-3 through the lateral ventricle. At 6 h after injection, the protein components of uterine fluid of rats in the experimental and control groups were analyzed using liquid chromatography (LC)-tandem mass spectrometry (MS/MS). Differentially expressed proteins (DEPs) were analyzed using the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. Protein-protein interactions (PPI) were investigated using the STRING database. PPI networks were then established before hub proteins were selected using OmicsBean software. The expression of one of the hub proteins, Kras, was then detected using western blot analysis. Cell Counting Kit-8, Annexin V-FITC/PI, reverse transcription-quantitative PCR and western blotting were also performed to analyze cell viability and apoptosis. In total, 417 DEPs were obtained using LC-MS/MS, including 279 upregulated and 138 downregulated proteins. GO analysis revealed that the majority of the DEPs were secretory proteins. According to KEGG enrichment analysis, the DEPs found were generally involved in tumor-associated pathways. In particular, five hub proteins, namely G protein subunit α (Gna)13, Gnaq, Gnai3, Kras and MMP9, were obtained following PPI network analysis. Western blot analysis showed that expression of the hub protein Kras was downregulated following treatment with 10,000 ng/ml RFRP-3. RFRP-3 treatment (10,000 ng/ml) also suppressed HEC-1A cell viability, induced apoptosis, downregulated Bcl-2 and upregulated Bax protein expression, compared with those in the control group. In addition, compared with those in the control group, RFRP-3 significantly reduced the mRNA expression levels of PI3K, AKT and mTOR, while upregulating those of LC3-II. Compared with those in the control group, RFRP-3 significantly decreased the protein expression levels of PI3K, AKT, mTOR and p62, in addition to decreasing AKT phosphorylation. By contrast, RFRP-3 significantly increased the LC3-II/I ratio and G protein-coupled receptor 147 (GPR147) protein expression. In conclusion, the present data suggest that RFRP-3 can alter the protein expression profile of the uterine fluid of OEP rats by upregulating MMP9 expression whilst downregulating that of key hub proteins Gna13, GnaQ, Gnai3 and Kras. Furthermore, RFRP-3 can inhibit HEC-1A cell viability while promoting apoptosis. The underlying molecular mechanism may involve activation of GPR147 receptor by the direct binding of RFRP-3, which further downregulates the hub protein Kras to switch on the PI3K/AKT/mTOR pathway. This subsequently reduces the Bcl-2 expression and promotes Bax expression to induce autophagy.

Abstract
OBJECTIVE Several studies have found that MMP-9, one of the extracellular matrix-degrading proteinases, was involved in EC's (endometrial cancer) clinical progression and prognosis. However, the results involving the associations of MMP-9 expression with risk, clinical features and prognosis of EC were conflicting. Therefore, we performed a systematic review and meta-analysis to clarify the correlation of MMP-9 expression with EC. METHODS Relative studies involving the associations between MMP-9 expression and EC were retrieved from PubMed, Embase, Web of Science and CNKI (China National Knowledge Infrastructure) electronic databases. OR (odds ratio) with 95% CI (confidence interval) was applied to evaluate the associations of MMP-9 expression with risk and clinical features of EC. Furthermore, we evaluated the role of MMP-9 expression in prognosis of EC using HR and 95% CI. The funnel plots and Begg test were used to assess the publication bias. RESULTS A total of 28 eligible studies were acquired from Pubmed, Embase, Web of science and CNKI databases. We found MMP-9 overexpression was significantly associated with the risk of EC (OR = 11.02, 95% CI = 7.51-16.16, P < 0.05). In the meantime, MMP-9 overexpression was significantly associated with the tumor grade, FIGO stage, lymph node metastasis and myometrial invasion (Tumor grade: OR = 1.68, 95% CI = 1.09-2.58, P < 0.05; FIGO stage: OR = 3.25, 95% CI = 1.73-6.08, P < 0.05; Lymph node metastasis: OR = 2.98, 95% CI = 1.27-7.03, P < 0.05; Myometrial invasion: OR = 2.42, 95% CI = 1.42-4.12, P < 0.05) in Asians. In addition, the overall results showed that MMP-9 overexpression predicted a worse prognosis of EC (OR = 1.82, 95% CI = 1.01-2.62, P < 0.05). CONCLUSIONS MMP-9 overexpression might be a potential predictor of poor clinical progression and prognosis of EC.

Abstract
Endometrial cancer (EC) is the most common gynecologic malignancy, and it arises in the inner part of the uterus. Identification of serum biomarkers is essential for diagnosing the disease at an early stage. In this study, we selected 44 healthy controls and 44 type I EC at tumor stage 1, and we used the Immuno-oncology panel and the Target 96 Oncology III panel to simultaneously detect the levels of 92 cancer-related proteins in serum, using a proximity extension assay. By applying this methodology, we identified 20 proteins, associated with the outcome at binary logistic regression, with a p-value below 0.01 for the first panel and 24 proteins with a p-value below 0.02 for the second one. The final multivariate logistic regression model, combining proteins from the two panels, generated a model with a sensitivity of 97.67% and a specificity of 83.72%. These results support the use of the proposed algorithm after a validation phase.

Abstract
Endometrial cancer is one of the most common gynecological malignancies, yet the molecular mechanisms that lead to tumor development and progression are still not fully established. Matrix metalloproteinases (MMPs) are a group of enzymes that play an important role in carcinogenesis. They are proteases involved in the degradation of the extracellular matrix (ECM) that surrounds the tumor and the affected tissue allows cell detachment from the primary tumor causing local invasion and metastasis formation. Recent investigations demonstrate significantly increased metalloproteinase and metalloproteinase inhibitor levels in patients with endometrial cancer compared to those with normal endometrium. In this review, we aim to show their clinical significance and possible use in the diagnosis and treatment of patients with endometrial cancer. We have critically summarized and reviewed the research on the role of MMPs in endometrial cancer.

Abstract
Endometrial cancer is the leading gynaecological malignancy in the western world and its incidence is rising in tandem with the global epidemic of obesity. Early diagnosis is key to improving survival, which at 5 years is less than 20% in advanced disease and over 90% in early-stage disease. As yet, there are no validated biological markers for its early detection. Advances in high-throughput technologies and machine learning techniques now offer unique and promising perspectives for biomarker discovery, especially through the integration of genomic, transcriptomic, proteomic, metabolomic and imaging data. Because the proteome closely mirrors the dynamic state of cells, tissues and organisms, proteomics has great potential to deliver clinically relevant biomarkers for cancer diagnosis. In this review, we present the current progress in endometrial cancer diagnostic biomarker discovery using proteomics. We describe the various mass spectrometry-based approaches and highlight the challenges inherent in biomarker discovery studies. We suggest novel strategies for endometrial cancer detection exploiting biologically important protein biomarkers and set the scene for future directions in endometrial cancer biomarker research.

Abstract
Background: Endometrial carcinomas are common gynecologic malignancies worldwide. In Egypt they represent
2.6 %. We evaluated the role of morphometry and MMP-9 immunohistochemical expression to differentiate atypical
endometrial hyperplasia from low grade endometrial adenocarcinoma. Methods: 60 cases of endometrial lesions that
included 25 cases of complex endometrial hyperplasia with atypia, 25 cases of low grade endometrioid adenocarcinoma,
in addition to 10 cases of proliferative endometrium as a control group. Morphometric measurements and D-score
were evaluated. MMP9 was performed using streptavidin –biotin immunoperoxidase system. Results: D score was
more than 1 in 100% of cases of proliferative endometrium. In atypical hyperplasia 28 % of cases had a D-score more
than 1, 44% less than 0 and 28% of cases had a D score between 0 and 1 with uncertain prognosis. All carcinoma
cases had D-score less than 0. MMP9 was positive in all cases of the study but differ in its degree of expression;
proliferative endometrium with low expression. Atypical hyperplasia divided as 52% low expression and 48% high
expression. Most of the Endometrial adenocarcinoma cases (92%) showed high expression. There was significant
difference in expression of MMP9 in atypical endometrial hyperplasia and endometrial adenocarcinoma (p> 0.001).
Conclusion: The relation between MMP9 expression and D-score value in cases of atypical endometrial hyperplasia
was highly significant P>0.001Thus, incorporating both MMP9 immunoexpression and D-score value would increase
the accuracy of diagnosis of atypical endometrial hyperplasia and low grade endometrial adenocarcinoma.

Abstract
In patients with endometrial cancer (N=94), endometrial polyps (N=28), endometrial hyperplasia (N=25), and healthy women (N=77), the serum contents of MMP-2, MMP-7, MMP-9, TIMP-1, and TIMP-2 were measured by ELISA. Both carcinoma and benign neoplasms were accompanied by significant elevation of MMP-7 and TIMP-2 in blood serum. The greatest elevation (in comparison with the control) was observed for MMP-7, although serum concentration of this marker was practically identical in patients with carcinoma and benign tumors. In contrast, the levels of MMP-2 and TIMP-1 were lower in cancer patients in comparison with the control; in these patients, the levels of MMP-9 and TIMP-1 were also lower than the corresponding levels in patients with polyps and endometrial hyperplasia. There were no significant correlations between the levels of examined markers with tumor metastasizing, its histological structure, and differentiation degree of endometrial cancer. No differences were observed between examined serological markers in patients with polyps and endometrial hyperplasia of various severities. The examined MMPs and TIMPs cannot be advanced as potential diagnostic markers of endometrial cancer, but they can be used to monitor and prognosticate the disease and to assess effectiveness of the targeted therapy.

Abstract
Metalloproteinase matrix 11 (MMP11) is a member of the matrix metalloproteinase family, which are able to degrade extracellular matrix components, and may serve a central function in the enhancement of tumor-induced angiogenesis, cell migration, proliferation, apoptosis and connective tissue degradation. In the present study, MMP11 gene expression was investigated using the reverse transcription-polymerase chain reaction in 68 cases of type I endometrial carcinoma, and all data were analyzed in association with clinical characteristics. Overexpression of MMP11 was demonstrated in 75%, and sub-expression was demonstrated in 25%, of endometrial cancer cases. Sub-expression cases were associated with good histological parameters, including low histological grade (G1 and G2), early pathological stage, and absence of vascular invasion, metastasis and recurrence. In total, 76.4% of endometrial cancer cases with sub-expression were identified as early stage 1A and B; however, 23.6% of cases were identified as stage 2, with vascular invasion present in 29.4% of cases. On the other hand, cases which demonstrated overexpression with high ranges (>10 times more than control) were associated with adverse histopathological characteristics, including high grade tumor (G3) and vascular invasion. In conclusion, the increased expression of MMP11 may be used as a prognostic biomarker in patients with type 1 endometrial cancer.

Abstract
Tissue inhibitors of metalloproteinases (TIMPs) appear to affect many aspects of cancer biology, playing a crucial role in cell signaling by regulating cell growth, apoptosis, invasion, metastasis, angiogenesis, and genomic instability. The aim of the present study was to elucidate the diagnostic and prognostic utility of TIMP-1 and TIMP-2 in patients with colon cancer. Serum TIMP-1 and TIMP-2 concentrations were quantified using an enzyme-linked immunosorbent assay in 97 colon cancer patients. Elevated serum TIMP-1 levels were found in patients with advanced disease stage (p=0.0512) and poorly differentiated histopathological tumor grade (p=0.0059). Patients with increased TIMP-1 levels had shorter overall survival times (log-rank test, p=0.0143). Multivariate analysis also identified TIMP-1 as an independent prognostic factor (Cox regression analysis, p=0.0149). Serum TIMP-2 levels were not significantly associated with disease stage, histopathological grade or survival. In the subgroup of patients with well and moderately differentiated tumors, TIMP-1 and TIMP-2 were identified as independent prognostic factors (Cox regression analysis, p=0.0379 and p=0.0451, respectively). In conclusion, assessment of serum TIMP-1 can be considered a useful biomarker in colon cancer, whereas TIMP-2 appears to be of limited value.

Abstract
Angiogenesis (the growth of new blood vessels) is essential in most of the body’s physiological processes, such as in the normal functioning of the endometrium during and after the menstrual cycle. Vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP) are the mostly expressed angiogenic factors, especially, during the process of endometrial degeneration and remodeling. In carcinogenesis, tumor hypoxia-induced factors, through the process of “angiogenic switch”, stimulate the production of angiogenic factors, particularly VEGF and MMP. Subsequently, these angiogenic factors are associated with degradation, differentiation, proliferation, and migration of vascular endothelial cells, enhancing the formation of new blood vessels to supply the tumor with oxygen and nutrients. This process is equally significant for tumor development and metastasis. Hence, like in other cancers, the overexpression of MMP and VEGF in endometrial cancer (EC) seems to play a significant role in its tumorigenesis and metastasis. This research will discuss the influence of MMP and VEGF on angiogenesis, metastasis, and the prognosis of EC as well as the clinical importance of the factors in the diagnosis of EC.

Abstract
Introduction Endometrial cancer is the one of the most common cancers of the genital organ. HE4 and MMP2 are both proteins whose serum levels increase in endometrial cancer. Aim To explore the diagnostic potential of the serum levels of HE4 and MMP2 in patients with endometrial cancer and benign endometrial diseases. To assess the relationship between the serum levels of HE4 and MMP2 and the typical prognostic factors in patients with endometrial cancer. Materials and methods Included in the study was a group of 112 patients presenting with bleeding abnormalities at the Pomeranian Medical University in years 2012–2016. Serum HE4 concentrations were measured using the Elecsys Electrochemiluminescence Immunoassay (ECLIA). MMP2 concentrations were quantified in the serum using multiplex immunoassays. Results We observed statistically significant differences in mean serum levels of HE4 and MMP2 between the group of endometrial cancer patients and the group of patients with no changes in the endometrium (P=0.002/0.003). The diagnostic potential of HE4 and MMP2 in differentiation of high (International Federation of Gynecology and Obstetrics [FIGO] III and IV) vs low (FIGO I and II) clinical stage of tumor and prediction of cellular differentiation grade (G1 vs G3) on the basis of the analysis of the area under the curve is, respectively, 0.86 and 0.82 for HE4 and 0.82 and 0.74 for MMP2. The HE4 marker was significantly more specific than MMP2 in every study group and amounted to 93% vs 86% in all patients included in the analysis, 94% vs 84% in pre-menopausal patients and 84% vs 79% in post-menopausal patients. Conclusion HE4 and MMP2 are characterized by high specificity and may be useful as biomarkers in the diagnostics of endometrial cancer. When determined preoperatively, HE4 is correlated with the prognostic factors of endometrial cancer and may be helpful in the planning of individual treatment of endometrial cancer patients.

Abstract
The objective of this study was to investigate the effect of intermediate-conductance Ca(2+)-activated K(+) (KCa3.1) channels on the cell proliferation, cell cycle, apoptosis, migration, and invasion in endometrial cancer (EC) cells. Human EC cell lines HEC-1-A and Ishikawa were cultured in vitro and transfected with recombinant plasmid containing KCa3.1-targeting shRNA. RT-qPCR and Western blot were used to examine the mRNA and protein expression levels of KCa3.1 channels in transfected cells. In addition, the specific inhibitor of KCa3.1, TRAM-34, was used to examine the effect of KCa3.1 blockage on migration capacity and invasiveness of EC cells using transwell assay. Proliferation and apoptotic rates of EC cells transfected with KCa3.1 shRNA or treated with TRAM-34 were analyzed using MTT, BrdU incorporation assay, and flow cytometry. Expression of cell cycle proteins and metalloproteinase-2 (MMP-2) was evaluated by RT-qPCR and Western blotting. TRAM-34 treatment and KCa3.1 silencing using shRNA dramatically suppressed both the mRNA and protein expression of KCa3.1 channels (P < 0.01) compared with control groups. Blockage of KCa3.1 by TRAM-34 treatment and KCa3.1 shRNA transfection exerted inhibitory effect on cell growth of both EC cell lines, as demonstrated by increased cell population at G0-G1 phase and decreased cell population at S phase. However, both the treatments did not result in significant changes in the apoptotic rate (P > 0.05) compared to controls. Protein expressions of cyclin D1, cyclin E, and survivin were significantly decreased in the experimental groups comparing to control. We showed that TRAM-34 treatment led to significantly inhibited migration, invasion, and MMP-2 expression in HEC-1-A and Ishikawa cells, compared with the control group (P < 0.01). Blockage of KCa3.1 channel activity or expression inhibits cell proliferation and cell cycle progression without inducing apoptosis in EC cells. Moreover, TRAM-34 could reduce the ability of EC cells to migrate and invade, which might be related to reduced expression of MMP-2.

Abstract
Glutathione-S-transferases mu 2 (GSTM2), a kind of important Phase II antioxidant enzyme of eukaryotes, is degraded by nonsense mediated mRNA decay due to a C27T substitution in the fifth exon of pigs. As a reproductive performance-related gene, GSTM2 is involved in embryo implantation, whereas, functional deficiency of GSTM2 induces pre- or post-natal death in piglets potentially. To have some insight into the role of GSTM2 in embryo development, high throughput RNA sequencing is performed using the swine testis cells (ST) with the deletion of GSTM2. Some embryo development-related genes are observed from a total of 242 differentially expressed genes, including STAT1, SRC, IL-8, DUSP family, CCL family and integrin family. GSTM2 affects expression of SRC, OPN, and SLCs. GSTM2 suppresses phosphorylation of STAT1 by binding to STAT1. In addition, as an important transcription factor, STAT1 regulates expression of uterus receptive-related genes including CCLs, IRF9, IFITs, MXs, and OAS. The present study provides evidence to molecular mechanism of GSTM2 modulating embryo development.

Abstract
Skin cancer is one of the most common types of malignancy in the world. UV radiation is known as the primary environmental carcinogen responsible for skin cancer development. However, UV radiation is a ubiquitous substance existing in the environment and the physiological effect of UV radiation is consistently ignored. Therefore, in the present study, the physiological effect of UV radiation on inhibition of skin cancer was investigated. Normal mouse skin was processing by no pre-radiation or pre-radiation of low-dose UV before a medium or high dose of UV radiation. We found that the low-dose pre-radiated mouse skin tissue exhibited low skin inflammation, skin ROS production and consequently low skin epithelial hyperplasia after the medium-dose UV radiation compared with the no pre-radiated mouse. However, this inhibition was not indicated in the high-dose UV radiation group after low-dose pre-radiation. Furthermore, western blot analysis and gelatin zymography showed low expression and activation of MMP2 in the skin tissues processed following medium-dose radiation, but not in tissues treated with high-dose radiation after a low-dose pre-radiation. Further investigation of MMP2 inhibitors of TIMP2/TIMP4 showed an upregulated TIMP2 expression, but not TIMP4. Collectively, these data indicate that low-dose pre-radiation attenuates the skin inflammation and ROS production induced by medium-dose UV radiation and also elevates TIMP2 to withstand MMP2, therefore suppressing skin hyperplasia. The present study indicates a novel concept or prophylactic function of moderate UV radiation as a preventative strategy.

Abstract
The risk of endometrial hyperplasia (EH) progressing into endometrioid endometrial cancer ranges from 1% for simple EH without atypia (EHWA) to 46.2% for atypical EH (AEH). Differentiation between both entities is crucial to determine optimal management. As preoperative diagnosis of AEH can be difficult, we aimed to establish clusters of immunohistochemical markers to distinguish EHWA from AEH. We studied 13 immunohistochemical markers (steroid receptors, pro/anti-apoptotic proteins, metalloproteinases (MMP), tissue inhibitor of metalloproteinase (TIMP), CD44 isoforms) known for their role in endometrial pathology. Using supervised clustering, we determined clusters of co-expressed proteins which contributed the most in differentiating EHWA from AEH. From 39 tissue samples (17 EHWA and 22 AEH), we found three clusters of co-expressed proteins: Cluster 1 included two proteins (over-expression of estrogen receptor (ER) and under-expression of progesterone receptor (PR) B in AEH compared to EHWA); Cluster 2: an ER, PR A, MMP-2 and TIMP-1 over-expression and a PR B and TIMP-2 under-expression; Cluster 3: over-expression of ER and MMP-7 and under-expression of PR B and TIMP-2. AEH can be accurately distinguished from EHWA using a supervised clustering of immunohistochemical markers. This promising approach could be useful to improve the preoperative diagnosis of EH.

Abstract
Objective. The aim of this study was to evaluate the combined effects of MMP-2 and TIMP-2 protein immunoreactivities on the prognosis in endometrial carcinoma.
Methods. Paraffin-embedded tissue samples from 225 primary endometrioid adenocarcinomas and 13 histologies other than endometrioid adenocarcinoma were immunohistochemically stained for MMP-2 and TIMP-2. Results. In Kaplan-Meier analysis, the 5-year cancer-specific survival rate of the endometrioid adenocarcinoma patients with negative MMP-2 and positive TIMP-2 staining was 100%, whereas only 78% of patients presenting with positive MMP-2 and negative TIMP-2 staining results were alive at that time. In Cox regression analysis, patients with positive MMP-2 and negative TIMP-2 immunostaining had a 4.7-fold relative risk of death from endometrial carcinoma compared to the group of patients with negative MMP-2 and positive or negative TIMP-2 immunoreaction. Conclusions. MMP-2 seems to be the main metalloproteinase determining the prognosis in endometrial carcinoma. Combination of strong MMP-2 and weak TIMP-2 immunostainings was the most potent prognostic marker for poor survival.

Abstract
OBJECTIVE To identify independent prognostic variables for surgically staged intermediate risk endometrial carcinoma as defined by the Gynecologic Oncology Group 99 (GOG99) criteria. STUDY DESIGN Retrospective study of 239 patients with FIGO stage IB-occult IIB endometrioid type endometrial cancer, who were primarily treated with comprehensive staging surgery. Data were collected on clinicopathological variables, extent of primary surgery, postoperative adjuvant treatment, and patterns of recurrences. Kaplan-Meier survival curves were used to estimate disease free survival (DFS) and overall survival (OS), and multivariate Cox regression models were used to identify independent prognostic variables. The median follow-up time was 67 months (range, 12-183 months). RESULTS The 5-year DFS and OS were 91.0% and 93.0%, respectively. On univariate Kaplan-Meier analysis, age>60 years, deep myometrial invasion (MI), presence of lymph vascular invasion (LVSI), and negative progesterone receptor (PR) status were significantly associated with diminished 5-year DFS and OS. The univariate analysis on patterns of failures demonstrated that patients with older age or positive LVSI were more inclined to develop locoregional recurrence, while PR status and the depth of MI had a statistically significant impact on distant failure. On multivariate analysis, PR status, age, and the depth of MI were independent prognostic variables for 5-year DFS, and age was the only independent prognostic variable for 5-year OS. LVSI and age were independent prognostic variables for locoregional recurrence, while PR status and depth of MI were independent prognostic variables for distant recurrence. CONCLUSIONS Age, depth of MI, PR status and presence of LVSI are of independent prognostic value for intermediate risk endometrial cancer. The presence of these variables warrants consideration when deciding upon treatment strategies.

Abstract
MicroRNAs (miRNAs) play important roles in tumorigenesis and metastasis. In this study, we investigated miR-200b expression in endometrial adenocarcinomas and normal adjacent tissues and found that miR-200b is more highly expressed in cancer tissues than in normal adjacent tissues. A novel target of miR-200b, tissue inhibitor of metalloproteinase 2 (TIMP2), was predicted using a bioinformatics approach and was confirmed in human endometrial cancer cell line HEC-1A cells by luciferase assay, quantitative real-time polymerase chain reaction, western blotting, and enzyme-linked immunosorbent assay. We found that miR-200b repressed TIMP2 expression at both the messenger RNA and protein levels, although a family member, miR-200a, had no such effect. Using reverse gelatin zymography, we showed that miR-200b enhances matrix metallopeptidase 2 (MMP2) activity by downregulating TIMP2 expression in HEC-1A cells. These data suggest that miR-200b may play an important role in the metastasis of endometrial adenocarcinomas.

Abstract
A number of microRNAs (miRNAs), including miR-200 family, are aberrantly expressed in endometriosis and endometrial cancer. Here we assessed the expression and functional aspects of miR-200c in endometrial tissues (N = 52) from normal endometrial biopsies (N = 15), endometrial tissues including those exposed to hormonal therapies (N = 20), and grade I-III endometrial cancer (N = 17). miR-200c expression was elevated in normal endometrial biopsies from mid- and late-luteal phase, and in endometrial tumors as compared to endometrial tissues from peri- and postmenopausal period (P < .05) and its pattern of temporal expression displayed an inverse relationship with the expression of ZEBs. The expression of E-cadherin (CDH1) varied, but expressed at low levels, specifically in endometrial tissues and endometrial tumors. The endometrial expression of ZEBs and CDH1 in patients who were exposed to Depo-Provera and gonadotropin-releasing hormone agonist GnRHa displayed a trend toward lower expression as compared to proliferative phase; however, treatment of Ishikawa cells with 17β-estradiol, progesterone, and medroxy progesterone acetate had modest effects on the expression of miR-200c and ZEBs without affecting CDH1 expression. Gain of function of miR-200c in Ishikawa cells repressed ZEBs, as well as VEGFA, FLT1, IKKβ, and KLF9 expression at transcriptional and translational levels through direct interaction with their respective 3'untranslated regions and increased the rate of their proliferation. These results indicated that endometrial miR-200c expression undergoes dynamic changes during transition from normal into cancerous states; possibly influenced by hormonal milieu and by targeting the expression of specific genes with key regulatory functions in cellular transformation, inflammation, and angiogenesis may influence these events during normal and disease progression.

Abstract
Invasion of the trophoblast into the maternal decidua is regulated by both the trophoectoderm and the endometrial stroma, and entails the action of tissue remodeling enzymes. Trophoblast invasion requires the action of metalloproteinases (MMPs) to degrade extracellular matrix (ECM) proteins and in turn, decidual cells express tissue inhibitors of MMPs (TIMPs). The balance between these promoting and restraining factors is a key event for the successful outcome of pregnancy. Gene expression is post-transcriptionally regulated by histone deacetylases (HDACs) that unpacks condensed chromatin activating gene expression. In this study we analyze the effect of histone acetylation on the expression of tissue remodeling enzymes and activity of human endometrial stromal cells (hESCs) related to trophoblast invasion control. Treatment of hESCs with the HDAC inhibitor trichostatin A (TSA) increased the expression of TIMP-1 and TIMP-3 while decreased MMP-2, MMP-9 and uPA and have an inhibitory effect on trophoblast invasion. Moreover, histone acetylation is detected at the promoters of TIMP-1 and TIMP-3 genes in TSA-treated. In addition, in an in vitro decidualized hESCs model, the increase of TIMP-1 and TIMP-3 expression is associated with histone acetylation at the promoters of these genes. Our results demonstrate that histone acetylation disrupt the balance of ECM modulators provoking a restrain of trophoblast invasion. These findings are important as an epigenetic mechanism that can be used to control trophoblast invasion.

Abstract
Tissue inhibitors of metalloproteinases are important regulators of metalloproteinase activity, and the balance of active enzyme and inhibitor is a critical determinant of tumor cell invasiveness. This study aimed to evaluate the prognostic and clinical implications of the two main inhibitors of matrix metalloproteinases, TIMP-1 and TIMP-2, in endometrial carcinoma. The material consisted of 241 patients with primary endometrial carcinoma. The median follow-up time was 77 months. Expressions of TIMP-1 and TIMP-2 proteins were examined in paraffin-embedded tumor sections by immunohistochemical methods. Positive staining for TIMP-1 and -2 was observed in 88% and 86% of the primary tumors, respectively. The Kaplan-Meier analysis showed that the 5-year cancer-specific survival rate of the patients with TIMP-2 positive immunostaining was 89% and that of the TIMP-2 negative patients 78%. Positive immunoreaction for TIMP-2 correlated with favorable cancer-specific and overall survival. When including only endometrioid adenocarcinomas, a similar trend towards favorable survival was seen. Excluding stage IA carcinomas, the difference became again statistically significant. For TIMP-1, there was no statistically significant association with overall or cancer-specific survival. The Cox regression analysis showed stage, grade and TIMP-2 to be significant predictors of survival. We suggest that TIMP-2 may have a more important role in endometrial carcinoma progression than TIMP-1 and might serve as a potential marker for favorable prognosis in this type of cancer.

Abstract
Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are involved in tumor invasion, but their prognostic significance is still under discussion. We set out to analyze the epithelial and stromal expression of MMP-2, MMP-7, MMP-9, MT1-MMP, TIMP-1 and TIMP-2 in advanced epithelial ovarian cancers and to assess their prognostic value. A tissue microarray of malignant ovarian tumors from 69 patients was constructed. Immunostaining results were scored using the HSCORE and assessed by univariate analysis with Bonferroni correction and classical multidimensional scaling (CMDS). Kaplan-Meier survival curves calculated with regard to patient and tumor characteristics were compared by the log-rank test. Patients treated by primary surgery (n=43) had a higher tumor size and a trend toward higher epithelial MMP and TIMP expression than those treated by interval surgery (n=26). Optimal cytoreduction (residue ≤ 1 cm) was obtained in 27 and 18 patients, respectively. Clinical and histological characteristics were not different in patients with optimal cytoreduction and those with suboptimal cytoreduction. The expression of epithelial MMP-9 (P=0.002) and TIMP-2 (P=0.026) were higher in the latter group. CMDS failed to demonstrate any influence of MMP and TIMP expression with regard to cytoreduction outcome. MMP and TIMP expression did not influence survival. Their prognostic values were outweighed by histological type, lymph node involvement and cytoreduction. Standard statistical analysis adjusted after Bonferroni correction and CMDS reduced the relevance of MMPs and TIMPs in the prognosis of patients with advanced ovarian cancer.

Abstract
Tissue inhibitors of metalloproteinases (TIMPs) play an important role in extracellular matrix homeostasis by regulating MMP activity. Although they were initially considered inhibitors of tumor growth and metastasis, recently their role in cancer progression has been controversial. The aim of our study was to compare the immunohistochemical expression of TIMP1 and TIMP2 between an uncontrollably invasive phenomenon (cancer) and an "in situ" process (trophoblast invasion) in an effort to assess any differential role of these molecules between these two distinct phenomena and therefore to understand better their contribution in cancer invasion and migration. We performed an immunohistochemical analysis of 50 carcinomas (colorectal, gastric, breast, pulmonary, and renal) and 40 first trimester gestations. The marker expression was evaluated semiquantitatively, separately in cancer parenchymal and trophoblastic cells as well as in malignant stromal and decidual cells, according to a percentage scale (0, <10, 10-50, and >50%) and according to staining intensity (0, +, ++, and +++). Our results showed that there was no statistically significant difference in TIMP1 expression between cancer parenchymal cells and trophoblastic cells. On the other hand, TIMP1 was expressed more often in decidual cells than in cancer stromal cells. Immunostaining for TIMP2 was more extensive and intense both in trophoblastic and decidual cells than in cancer parenchymal and stromal cells, respectively. The reduced expression of TIMP2 in metastatic carcinomas by comparison with non-metastatic gestation specimens underlines its importance in cancer invasion and migration. On the other hand, TIMP1 was more expressed in decidua than cancer stroma, but at the same time showed no statistically significant difference between cancer parenchyma and trophoblasts, highlighting its multifunctional activity in cancer progression.

Abstract
BACKGROUND Menstruation is associated with a striking increase in matrix metalloproteinase (MMP) activity. However, it is still unknown whether the level of MMP activity correlates with the amount of menstrual bleeding. METHODS We used histochemistry to investigate the degradation of the extracellular matrix (ECM), and immunohistochemical labelling and zymographic analysis to determine the level of expression and activity of MMP-2 and -9, and of their tissue inhibitors (TIMPs) -1, -2 and -3, in endometria sampled during menstruation in 14 women experiencing excessive menstrual bleeding and in 10 women successfully treated for menorrhagia by thermal ablation of the endometrium. RESULTS After thermal ablation, regenerated menstrual endometria showed reduced areas of collagen fibre lysis and increased content of TIMP-1 and TIMP-2 compared with endometria from non-treated menorrhagic women. Surprisingly, treated endometria contained more latent gelatinase A (proMMP-2) but a lower proportion of the active form of gelatinase B (MMP-9) than non-treated endometria. CONCLUSIONS These results suggest that ECM degradation is decreased at menstruation in the endometrium regenerated after thermal ablation, mostly because of an increased TIMP expression. This represents the first molecular explanation for the decreased amount of menstrual bleeding.

Abstract
BACKGROUND The levonorgestrel-releasing intrauterine system (LNG-IUS) is an effective contraceptive and has many non-contraceptive health benefits. However, it is commonly associated with irregular endometrial bleeding. Metalloproteinases contribute to extracellular matrix (ECM) remodelling and regulate bleeding during the menstrual cycle. Enhanced metalloproteinase expression participates in the pathogenesis of breakthrough bleeding. Thus the objective of this study was to compare matrix metalloproteinase (MMP) expression in endometrium during luteal phase and in short-term (1 month) and long-term (> or =6 months) LNG-IUS users. METHODS MMP expression was analysed by semi-quantitative RT-PCR and immunohistochemistry. Gelatinase activity was determined by gelatin zymography. RESULTS MMP-1, -2, -3, -7, -9 and -12 mRNAs levels were increased, whereas that of MMP-26 was decreased in the endometrium of LNG-IUS users. MMP-1, -2, -3, -7 and -9 were localized by immunohistochemistry in all biopsies in the short-term group but in only 0-27% in the control group. The incidence of positive immunostaining for MMP-2 and -3 decreased significantly in the long-term compared with short-term LNG-IUS users. MMP-26 was localized in all biopsies from the control group but in only 14 and 25% from the short- and long-term LNG-IUS groups, respectively. In both LNG groups, the numbers of macrophages (the major source of MMP-12) was increased. CONCLUSIONS MMP-1, active MMP-2, MMP-3, MMP-7, MMP-9 and MMP-12 are more prevalent in the short-term LNG-IUS group, suggesting their important contribution to ECM breakdown and transient bleeding. The decrease in the percentage of women expressing MMP-2 and -3 might contribute to the decreased occurrence of unwanted spotting and bleeding in long-term LNG-IUS users.

Abstract
OBJECTIVE The objective of this study was to analyze the expression of matrix metalloproteinases (MMPs) 1, 7, and 26 in odontogenic keratocysts (OKCs) associated with Gorlin syndrome (SOKCs) and nonsyndrome OKCs (NSOKCs). STUDY DESIGN Twenty-one SOKCs and 20 NSOKCs were evaluated for epithelial expression of MMP-1, MMP-7, and MMP-26 and for mesenchymal expression of MMP-1 by immunohistochemistry. RESULTS Strong epithelial positivity to MMP-1 was observed in 76% of SOKCs and in 15% of NSOKCs (P < .05). Strong mesenchymal immunoreactivity to MMP-1 was observed in 38% of SOKCs and in 20% of NSOKCs (P > .05). Epithelial immunoreactivity to MMP-7 was strongly positive in 67% of SOKCs and in 40% of NSOKCs (P > .05). For MMP-26, strong positivity was found in 62% of SOKCs, in contrast to 35% of NSOKCs (P > .05). CONCLUSION MMPs-1, -7 and -26 may play important roles in the biology of OKCs. Furthermore, the presence of these proteases at higher levels in SOKCs may help to explain increased OKC aggressiveness associated with nevoid basal cell carcinoma syndrome.

Abstract
Recent published data have demonstrated elevated levels of human GH (hGH) in endometriosis and endometrial adenocarcinoma. Herein, we demonstrate that autocrine production of hGH can enhance the in vitro and in vivo oncogenic potential of endometrial carcinoma cells. Forced expression of hGH in endometrial carcinoma cell lines RL95-2 and AN3 resulted in an increased total cell number through enhanced cell cycle progression and decreased apoptotic cell death. In addition, autocrine hGH expression in endometrial carcinoma cells promoted anchorage-independent growth and increased cell migration/invasion in vitro. In a xenograft model of human endometrial carcinoma, autocrine hGH enhanced tumor size and progression. Changes in endometrial carcinoma cell gene expression stimulated by autocrine hGH was consistent with the altered in vitro and in vivo behavior. Functional antagonism of hGH in wild-type RL95-2 cells significantly reduced cell proliferation, cell survival, and anchorage-independent cell growth. These studies demonstrate a functional role for autocrine hGH in the development and progression of endometrial carcinoma and indicate potential therapeutic relevance of hGH antagonism in the treatment of endometrial carcinoma.

Abstract
We have investigated the production of metalloproteinases (MMP-1, MMP-2, MMP-9) and tissue inhibitors of metalloproteinases (TIMP-1 and TIMP-2) in bone marrow stromal cells (BMSCs) of patients with multiple myeloma (MM) and a healthy control. The new findings of this paper is that BMSCs of the MM patients exhibited intrinsic MMP-1, MMP-2 and TIMP-2 overproduction. Production of MMP-1, TIMP-2 and activation of MMP-2 was additionally enhanced in co-cultures of BMSCs with RPMI8226 cells. The ratio between MMP-2 and TIMP-2 was significantly higher in BMSCs of the MM patients than in control. BMSCs of both the control and the MM patients exhibited the presence of MMP-9 latent form, but in co-cultures RPMI8226 cells were the main producers of this metalloproteinase.

Abstract
MMP-7 expression is highly regulated at the level of transcription. An understanding of how the MMP-7 gene is regulated is critical to elucidate the mechanisms of MMP-7 overexpression in the early tumor development. In the present study, increased mRNA and protein expressions of MMP-7 were observed in MCF-7 cells stably overexpressing HER2 (MCF-7/HER2). The promoter activity of MMP-7 gene was upregulated in MCF-7/HER2 cells and significantly enhanced by HRG induction. Examination of the MMP-7 promoter sequence revealed three potential STAT3 binding sites within the proximal region. MMP-7 promoter activity was remarkably induced in MCF-7 cells expressing the constitutively activated STAT3 (MCF-7/STAT3C). RT-PCR and Western blot analysis confirmed the expression upregulation of mRNA and protein of MMP-7 in the MCF-7/STAT3C cells. Binding of STAT3 to MMP-7 promoter was verified by ChIP and the critical STAT3 element within the MMP-7 promoter identified by the mutagenesis of the core STAT3 recognition sequence. Increased STAT3 phosphorylation was observed in either HER2 overexpressing cells or HRG-induced cells. The data indicate that HRG-induced HER2-dependent transcriptional upregulation and protein secretion of MMP-7 are mediated by activated STAT3. The expression of MMP-7 may be attributed to HER2/STAT3 activation.

Abstract
BACKGROUND The metalloproteinases (MMPs) are a family of proteolytic enzymes involved in tissue remodeling and cell migration. Endometrial tissue remodeling proceeds during the menstrual cycle and requires a temporary and spatially balanced expression of several different MMPs. Various members of the MMPs also seem to play an important role in the invasion process of endometriosis; however, so far only a limited number of studies have focused on membrane-associated MMPs. METHODS The present study investigated the expression of membrane-type 5 metalloproteinase (MT5-MMP) in the human endometrium and endometriotic lesions by microarray hybridization, real-time polymerase chain reaction (PCR) and immunofluorescence. RESULTS Both the gene chip expression analyses as well as PCR indicated expression of MT5-MMP in normal human endometrium and strongly elevated transcript levels in most peritoneal endometriosis lesions analyzed. Moreover we detected enhanced MT5-MMP expression in the eutopic endometrium from patients suffering from endometriosis, further supporting a role of MT5-MMP in the formation of endometriosis. Immunohistochemical analysis was used to determine the intracellular localization and tissue distribution of MT5-MMP. While the MT5-MMP antigen expression could be clearly attributed to the membrane of epithelial cells, a highly complex differential immunohistochemical staining of MT5-MMP in the various compartments of endometrial tissue was observed. The strongest staining was seen in luminal epithelial cells, whereas endometrial glands frequently showed partial expression of MT5-MMP. CONCLUSION Our microarray analysis and real-time PCR of MT5-MMP transcripts may point to an elevated tissue remodeling and cell migration in endometrium from endometriosis patients as implied by the function of related MMPs.

Abstract
BACKGROUND To date, tools to study metastasis in endometrial cancers are insufficiently developed. The aim of this study was to characterize the cell line EN-1078D, a new endometrial carcinoma cell line derived from a metastasis to the ovary. METHODS AND RESULTS Cells were characterized using cytology, transmission electron microscopy, karyotyping and morphological appearance in culture. Molecular features were determined by RT-PCR, Western Blot, FISH and sequencing. MTT proliferation assays were performed to investigate the sensitivity of EN-1078D to anticancer agents such as cisplatin and doxorubicin. Also, subcutaneous and intravenous injections in nude mice were done to test the tumorigenic and metastatic properties of EN-1078D cells. Our results indicate that EN-1078D cells express both oestrogen receptors isoforms (ER alpha and ER beta) and also low levels of progesterone receptor B (PR-B). In addition, this cell line expresses high levels of MMP-2 and MMP-14 mRNA, low levels of TIMP-1 and TIMP-2 transcripts and no detectable levels of MMP-9 mRNA. Moreover, all nude mice developed tumors by subcutaneous injections and cell invasion was observed in vitro in response to TGF-beta 3. Her-2/neu was not overamplified but mutations in the C-2 domain of PTEN gene as well as codon 12 of the K-Ras gene were found. Finally, EN-1078D shows sensitivity to drugs commonly used in chemotherapy such as cisplatin and doxorubicin: IC50 of 2.8 microM of cisplatin after 72 hours of exposure and 0.54 microM of doxorubicin after 48 hours. CONCLUSION Taken together, these results suggest that EN-1078D will be an excellent tool to study the properties of metastatic endometrial cancer cells in vitro and their regulation by sex steroids.

Abstract
Endometriosis is an estrogen-correlated benign disease characterized by a marked ability of endometrial-like cells to invade and proliferate outside uterine cavity, resembling for some invasive aspect the cancer growth. The molecular mechanisms regulating endometrial cell invasiveness are mostly unknown, although interactions between extracellular matrix (ECM) proteins and their transmembrane receptors, integrins, are likely to play a central role. In particular, laminin (Ln)-5 could be closely involved, as it is in cancer. We have investigated the expression of Ln-1, Ln-5, and collagen IV (Coll IV) ECM proteins and their receptors, alpha3beta1 and alpha6beta4 integrins, in atrophic, proliferative, and secretive endometrium and in endometriosis. The results show that Ln-5, but not Ln-I and Coll IV, is altered in secretive endometrium as well as in endometriosis tissues. No alterations are observed in atrophic or proliferative endometrium. Consistently, the polarization of both integrin subunits alpha3 and beta1, but not alpha6 and beta4, is altered in secretive endometrium and endometriosis tissues, but not in atrophic and proliferative endometrium. These results seem to suggest that Ln-5 and alpha3beta1 could be involved in the invasive mechanism of endometriosis. The altered expression of Ln-5, by upregulating matrix metalloproteases activity, suggest an invading process similar to that of many cancer processes.
