  • Summary: The level of actin-binding proteins as well as the total calpain activity were enhanced in endometrium carcinoma tissues compared to endometrial hyperplasia, suggesting that levels of thymosin β-4, cofilin and total calPain activity are independent cancer risk factors in patients with endometrioid EC and may be considered as predictive biomarkers.

  • Snippet 1 (score: 0.504) > Endometrium carcinomas (EC) are the most common gynecological malignancy worldwide, which are connected with considerable mortality [1]. The endometrioid adenocarcinoma is the most frequent histological variant, accounting for about 80 % of the disease cases. Risk factors for EC include age, obesity, menstrual, reproductive and lifestyle factors [2]. Hormonal and metabolic mechanisms are particularly strongly implicated in the pathogenesis of endometrioid adenocarcinoma [2][3][4]. This subtype is often preceded by precursor lesions, atypical endometrial hyperplasia [5]. Complex hyperplasia and atypical hyperplasia, in particular, are more likely progressed to cancer and therefore are commonly treated with a progestin or hysterectomy [6]. > Among the factors that may influence the inception and course of EC estrogens, components of signaling pathways, proteases, growth and transcriptional factors have been most intensively studied [7][8][9][10]. However, molecular mechanisms involved in EC development are not fully understood. Neoplastic cancer transformation and following cancer progression are associated with the basic cancer properties as disorders of the cell adhesion and locomotion. The acquirement of the malignant phenotype leads to changes in cell cytoskeleton, wich are important for epithelial cancer cell proliferation, migration and epithelialmesenchymal transition [11]. The remodeling of actin cytoskeleton plays a central role in generating force to drive cell locomotion, and the cytoskeleton remodeling is regulated by a plethora of actin-binding proteins (ABPs).

  • Evidence snippets:
  • Snippet 1 (score: 0.502) > Endometriosis is an estrogen-dependent disease, which serves as a precursor of ovarian cancer, especially clear cell carcinoma (OCCC) and endometrial carcinoma. Although micro-environmental factors such as oxidative stress, immune cell dysfunction, inflammation, steroid hormones, and stem cells required for malignant transformation have been found in endometriosis, the exact carcinogenic mechanism remains unclear. Recent research suggest that many putative driver genes and aberrant pathways including ARID1A mutations, PIK3CA mutations, MET activation, HNF-1β activation, and miRNAs dysfunction, play crucial roles in the malignant transformation of endometriosis to OCCC. The clinical features of OCCC are different from other histological types. Patients usually present with a large, unilateral pelvic mass, and occasionally have thromboembolic vascular complications. OCCC patients are easier to be resistant to chemotherapy, have a worse prognosis, and are usually difficult to treat. To improve the survival of OCCC patients, it is necessary to better understand its specific carcinogenic mechanism and explore new treatment strategy, including molecular target.

  • Summary: Three human endometrial cancer cell lines were used to investigate the responsiveness of cisplatin alone and in combination with potential repurposed drugs and potential strategies for enhancing the efficacy of cis platin to overcome drug resistance inendometrial carcinoma patients are suggested.
  • Evidence snippets:
  • Snippet 1 (score: 0.476) > Type I tumors also show microsatellite instability and PTEN (Phosphatase and Tensin Homology) mutations. PTEN is a tumor suppressor gene that negatively regulates the PI3K/AKT (Phosphatidylinosito 3-kinase/a serine/threonine protein kinase) signaling pathway, mutations within which contribute to the pathogenesis of endometrial carcinoma. Type II tumors exhibit p53 mutations and chromosomal instability [7]. p53 mutations are predictive of prognosis in endometrial cancer and are associated with unfavorable outcomes [8]. Considering all the various genes and signaling pathways potentially involved in the pathogenesis of endometrial cancer, strategies for targeting them would seem to be a reasonable therapeutic approach. > The primary cause of death from endometrial cancer is disease recurrence, leading to progressive growth of the tumor [9]. Although chemotherapy or radiotherapy can target most tumor cells, relapse occurs in many cases because of drug resistance. Cisplatin is a well-known chemotherapeutic drug that acts by crosslinking with the N 7 of guanine in DNA [10]. Its mode of action is related to its ability to interfere with DNA repair mechanisms, cause DNA damage, and then induce apoptosis in cancer cells [11]. In recent years, much research has focused on the role of oxidative stress, defined as an imbalance between reactive oxygen species (ROS) and antioxidants, in the pathophysiology of malignant transformation in endometriosis [12][13][14][15]. But oxidant/antioxidant imbalance is a double-edged sword that can promote both carcinogenesis and cancer cell death. Cisplatin induces ROS that triggers cell death [16]. On the other hand, cancer cells frequently develop resistance to cisplatin that has been attributed to three molecular mechanisms: increased DNA repair, altered cellular accumulation, and increased drug inactivation [17].

  • Snippet 1 (score: 0.463) > Detailed In June 2021, we conducted a search for this systematic review and meta-analysis. We included research on endometrial cancer molecular pathways and treatment outcomes. The terms molecular mechanisms, endometrial cancer, uterine cancer, treatment, and therapy were used in the search. We also looked through the reference lists of papers found during the initial search to see if there were any other studies that were relevant. Authors independently vetted titles and abstracts for inclusion. Fig. 3 depicts the search technique as well as the selection criteria. > The inclusion and exclusion criteria applied to select studies for the meta-analysis as showed in Table 1. Author name, year, drug/therapeutic agent, trial phase, median progression and medial overall survival rate, number of patients enrolled in each study, mean age of the study participants, and drugs molecular target were retrieved. Endometrial cancer is one of the most prevalent malignancies among women worldwide, with an increasing incidence and death rate in the United States [1]. Postmenopausal women, on average 60 years old when diagnosed, are the majority of those affected by this malignancy. Between the ages of 75 and 79, the largest prevalence occurs, with 85% of cases occurring after the age of 50 and only 5% occurring before the age of 40. These facts were also discovered through our meta-analysis as a total of 1049 patients enrolled in all included studies with mean age of > 60. Fig. 2 depicts some essential biological pathways involved in endometrial cancer development. All endometrial malignancies should be screened for DNA mismatch repair gene mutations, according to experts [25]. The majority of endometrial cancer patients require surgery, which involves hysterectomy, bilateral salpingo-oophorectomy, and lymph node assessment. Patients with unresectable illness or significant medical comorbidities may get nonsurgical treatment in the form of primary radiation with or without chemotherapy, or chemotherapy alone. Hormonal therapy might potentially be used to treat people who are medically inoperable but dont want surgery, radiation, or cytotoxic chemotherapy.

  • Snippet 1 (score: 0.449) > Endometriosis is a complex, multifactorial disorder characterized by the growth of endometrial-like tissue outside the uterine cavity. The intricacies of its molecular and cellular mechanisms highlight the challenges in fully understanding the disease and developing effective therapeutic strategies. This discussion synthesizes the primary theories of pathophysiology, cellular mechanisms, and molecular pathways involved in the disease, emphasizing the interplay of genetic, immunologic, and hormonal factors. > The pathogenesis of endometriosis involves multiple overlapping theories, none of which fully explain the heterogeneity of the disease. Retrograde menstruation, the most widely known hypothesis, provides a logical mechanism for the dissemination of endometrial cells to ectopic sites [106]. However, its inability to account for cases of endometriosis in non-menstruating individuals, males, or distant anatomical locations necessitates complementary explanations [107]. The vascular and lymphatic dissemination hypothesis further supports the notion of systemic spread, while the coelomic metaplasia theory extends the understanding of ectopic lesion formation, particularly in patients with Müllerian anomalies or postmenopausal women [108]. Genetic and epigenetic influences are emerging as crucial contributors to disease susceptibility and progression, highlighting the role of heritable factors and acquired molecular modifications in shaping cellular behaviors [109]. > Endometrial stem cells and progenitors, such as eMSCs and eEPs, are critical in the establishment of endometriotic lesions. Their unique capacity for adhesion, proliferation, and differentiation in ectopic environments distinguishes them as central players in disease progression [113]. The altered integrin and cadherin profiles in these cells enhance their ability to adhere to peritoneal surfaces, while the influence of the inflammatory microenvironment further supports their survival and growth. Notably, ESCs and SMCs contribute to lesion heterogeneity, with their potential origins spanning basal endometrial layers and reactivated coelomic epithelium [119]. Understanding the lineage and differentiation of these cells remains a critical area of research, with implications for diagnostic and therapeutic approaches.

  • Evidence snippets:
  • Snippet 1 (score: 0.449) > Endometrial cancer is one of the most common gynecologic malignancies, and the incidence of this cancer continues to increase [1]. During the prior several decades, progress in molecular biology has improved our understanding of the occurrence and development of EC. It has been established that the biological behavior of tumors is controlled by functional proteins within cells and the signaling pathways in which these proteins are involved. Therefore, studies on the structure and function of hub proteins in signaling pathways may be valuable for diagnosing EC and for determining targeted therapies for this disease. To date, research has examined a large number of EC-related genes and proteins that could potentially be used as biomarkers or targets for diagnosis or treatment [2,3]. However, most published papers regarding EC have focused on only a handful of genes and proteins. Although the research objectives of molecular biology are shifting from single genes or proteins to genomics or proteomics, there are a limited number of systematic studies of whole-genome expression in the context of EC. > At present, text mining (TM) technology is widely used in biomedical research to extract information from large quantities of biomedical literature and construct databases of disease-related genes, proteins, and molecular interactions [4,5]. In this study, we systematically characterized the expression of EC-associated genes by mining data from the PubMed document retrieval system. In addition, we used bioinformatics methods to analyze the functions, pathways, and networks of relevant hub proteins.

  • Snippet 1 (score: 0.447) > Objective Bladder carcinoma represents a significant challenge in oncology due to its heterogeneous molecular nature. This study aimed to identify key genetic factors and molecular pathways involved in bladder carcinoma pathogenesis to facilitate the development of targeted therapies. Material and Methods The top 30 genes associated with bladder carcinoma were retrieved from the disease gene network database. Comprehensive bioinformatic analysis was performed using various enrichment tools, including gene ontology biological process, cellular component, molecular function analyses, and pathway mapping through WikiPathways and metabolite associations through human metabolome database. Drug interactions were evaluated using DrugMatrix data. Results Gene ontology analysis revealed significant enrichment of cancer-related biological processes, cellular components, and molecular functions. Pathway analysis identified strong associations with head and neck squamous cell carcinoma, cancer pathways, pleural mesothelioma, endometrial cancer, and bladder cancer pathways. Key genes including CDKN2A, PTEN, EGFR, PIK3CA, HRAS, FGFR3, and TP53 were implicated across multiple pathways. Metabolite analysis showed significant associations with phosphatidylinositol derivatives, highlighting the importance of the PI3K pathway. Drug interaction analysis revealed potential modulatory effects of several compounds including sertraline, valproic acid, and hydroxyurea on gene expression patterns in bladder carcinoma. Conclusion This study provides comprehensive insights into the molecular underpinnings of bladder carcinoma, highlighting interconnected pathways and potential therapeutic targets. The significant overlap with other cancer types suggests common oncogenic mechanisms that could be exploited for therapeutic intervention. Further validation of these findings in clinical samples may facilitate the development of personalized treatment approaches for bladder carcinoma patients.

Its clinical symptoms include chronic anovulation, ultrasound visibility of polycystic ovary morphology, and hyperandrogenism [1]. PCOS is characterized by high heterogeneity, complex symptoms, and difficult treatment. The consequent endocrine and metabolic abnormalities can also lead to various complications and increase the risk of endometrial cancer (EC) [2]. Women with PCOS are 3-4 times more likely to develop endometrial cancer than healthy women [3]. > EC is the sixth most common malignant tumor in women, and its incidence and mortality continue to increase annually. It is estimated that the prevalence of this disease will increase by 50-100% by 2030 [4,5]. The primary clinical symptoms of EC include dysfunctional uterine bleeding, menorrhagia, menstrual irregularities, and infertility [6]. PCOS is a major risk factor for the development and progression of type I EC [7,8]. Elevated estrogen levels, hyperinsulinemia, and decreased apoptosis play key roles in the 2 of 25 occurrence [9,10]. However, the exact underlying molecular mechanism remains unclear. PCOS serum-derived exosomal miR-27a-5p stimulates EC cell migration and invasion [11]. Matà et al. [12] reported that overexpression of the PI3K/Akt signaling pathway underlies the development of endometrial hyperplasia and carcinogenesis in patients with PCOS characterized by insulin resistance (PCOS-IR). In addition, IGF1/IGFBP pathway-related genes may contribute to an increased risk of EC in women with PCOS [13]. However, the molecular mechanism underlying EC in patients with PCOS remains unclear. This has hindered effective clinical prevention and treatment. > Cell division cycle 6 (CDC6), sited on human chromosome 17q21.3, is a vital regulatory protein for the beginning of DNA copying in eukaryotic cells.

(11). > A recent characterization of 373 endometrial carcinomas using array-and sequencing-based technologies, through an integrated analysis of genomic, transcriptomic, and proteomic data by The Cancer Genome Atlas (TCGA) provided comprehensive information about pathway alterations and molecular mechanisms, describing four different molecular subgroups. Polymerase epsilon (POLE)-mutated subgroup with very high mutation rates (232×10 6 mutations/Mb) (ultramutated) is associated with good prognosis and account for 7-10% of endometrioid carcinomas. MSI subgroup with frequent hypermethylation of MLH1 promoter and elevated mutation rates (18× 10 6 mutations/Mb) account for 28-30% of endometrioid carcinomas. Low copy number alterations subgroup with low mutation rate (2.9×10 6 mutations/Mb) represents 39% of endometrioid carcinomas, and high copy number subgroup (serous-like) with low mutation rate (2.3× 10 6 mutations/Mb) but frequent TP53 mutations with worse prognosis represents serous carcinoma (94%). The candidate driver or pathogenic genes varied in all four subgroups, with 190 genes in the POLE subgroup, 21 in the MSI subgroup, 16 in the low copy number subgroup, and 8 in the high copy number subgroup (3,11,12) ( Table 2). > Endometrioid carcinomas were present in all four subgroups. Endometrioid carcinoma is generally characterized by frequent derangements of the PI3K-PTEN-AKT-mTOR, RAS-MEK-ERK, and canonical WNT-β-catenin pathways. Endometrial cancer presents more mutations than any other tumor type studied thus far in the PI3K/AKT pathway by TCGA. The PI3K-PTEN-AKT-mTOR signal transduction pathway regulates cell growth and survival, synthesis of specific proteins, and metabolism. The RAS-RAF

  • Snippet 1 (score: 0.441) > Endometrial cancer is the most common invasive gynecological malignancy in the United States, accounting for 45,000 new cancer cases and over 7,500 deaths annually [1]. However, molecular mechanisms underlying its etiology and pathophysiology are poorly understood. Endometrial carcinomas are derived from glandular epithelium and typically divided into two subtypes based on clinical, histological, and molecular characteristics [2,3]. Type I tumors, comprising 80% of cases, are generally well or moderately differentiated with endometrioid morphology and are associated with chronic unopposed estrogen exposure and hyperplasia. By contrast, type II tumors are more heterogeneous, poorly differentiated and may be estrogen independent, arising in a background of atrophic endometrium [2,4]. The prevalence of advanced stage, high-grade tumors, of both types, with recurrent metastatic disease is increasing [5,6]. Such cancers typically have a poorer prognosis and are refractory to current therapeutic regimens [7]. > Endometrioid tumors retain expression of estrogen (ER) and progesterone (PR) receptors [8], and estrogen is a critical regulator of endometrial proliferation [9,10]. Indeed, the majority of endometrial cancers are thought to arise due to unopposed estrogen action leading to hyperplasia and malignant transformation [2,11]. However, our understanding of the molecular mechanisms underlying the pathophysiology of endometrial cancer lags far behind that of other hormonedependent malignancies such as breast, prostate and ovarian cancer [2,8,12,13]. > The protein kinase C (PKC) family has been implicated in the regulation of numerous signal transduction pathways, modulating cell growth, differentiation, and survival [14][15][16]. In endometrial cancer cells and primary endometrial epithelium, expression of PKC is increased in response to treatment with estrogen and tamoxifen and may underlie the proliferative actions of these agents in the endometrium [17,18].

However, type II endometrial carcinoma is a less common type of serous or clear cell adenocarcinoma, accounting for only ~10% of endometrial tumors. They are poorly differentiated, estrogen-independent tumors, which are associated with atrophic endometrium and have poorer outcomes (8,9). Endometrial carcinoma is believed to arise from a variety of genetic alterations involving signaling pathways, activation of proto-oncogenes and inactivation of tumor suppressor genes. > The development and progression of each group of endometrial carcinoma follows distinct molecular mechanisms of oncogenesis, reflecting the presence of type-specific genetic alterations. Although there are well-established surgical, radio-and chemotherapeutic treatments, the identification and characterization of biomarkers is necessary for improving the understanding of molecular pathways of the disease and for the development of specific novel molecular targeted therapies, with the aim to achieve greater specificity in tumor progression and metastatic processes, and to accurately evaluate the prognosis, particularly for recurrent and unfavorable disease course (3,5,10,11). Phosphatase and tensin homolog (PTEN) was identified in 1997, and is a tumor suppressor gene located on chromosome 10 (10q23) that suppresses cell proliferation and differentiation and is involved in the insulin signaling pathway. The protein encoded by this gene is a 55-kDa protein composed of 403 amino acids, which has protein tyrosine phosphatase activities. PTEN protein negatively regulates the phosphatidylinositol 3-kinase (PI3K) signaling pathway. A downstream effector that emanates from PI3K is the Akt protein, which is a serine-threonine kinase. Therefore, PTEN protein can act through the Akt signaling pathway (12)(13)(14). PTEN protein under normal physiological conditions has an antagonistic effect on intracellular signaling pathways induced by integrin or growth factors. Furthermore, PTEN protein inhibits intracellular signaling, cell proliferation, cell migration and cellular adhesion formation.

A better understanding of mechanism underlying the progress of endometrial carcinoma is required to facilitate the development of effective therapeutic strategies. > A series of reports indicate that the epithelialmesenchymal transition (EMT) plays an important role in the tumorigenesis, progression, and chemoresistance of multiple carcinomas [3][4][5], including endometrial carcinoma [6]. During the EMT, epithelial cells undergo extensive alterations in gene expression, resulting in the loss of apical-basal polarity, the severing of intercellular adhesive junctions, and the degradation of basement membrane components [7]. In this way, they become mesenchymal cells with the characteristics of increased migration and invasion. The loss of E-cadherin is generally accepted as a hallmark of the EMT [8], which reduces cell-cell adhesion and destabilizes the epithelial architecture. This process is accompanied by increased expression of mesenchymal-related proteins, including N-cadherin, Vimentin, and fibronectin, which bestow a motile phenotype on cancer cells through changes in cellular architecture and cell-matrix interactions [9,10]. Many transcription factors, such as Snail and Slug, act as repressors of E-cadherin in response to TGF-β [11] and IGF-IR [12] signaling, and have been linked to the induction of the EMT under different cellular contexts. In endometrial carcinoma, alterations of EMT-related markers have been associated with metastatic disease and reduced survival [13,14]. Although the EMT has been broadly described in endometrial carcinoma, the molecular pathways involved are still poorly delineated. > As a hormone-dependent disease, endometrial carcinomas are sensitive to endogenous and exogenous estrogens, which are known risk factors for the disease.

  • Snippet 1 (score: 0.431) > In the pregenomic eras, highly integrated and complex circuitry of molecular signaling in NPC pathogenesis was only partially understood. Over the past decade, the knowledge of the molecular mechanisms in NPC carcinogenesis has been rapidly accumulated. Dysregulation and abnormal protein expression of molecules in certain signaling pathways involved in cellular functions including proliferation, adhesion, survival, and apoptosis has been demonstrated in the NPC cells. Detailed information on the complex network in signaling pathway leading to a coordinated pattern of gene expression and regulation in NPC will undoubtedly provide important clues to develop novel prognostic and therapeutic strategies for this cancer. Refining molecular markers into clinically relevant assays may assist in the detection of NPC in asymptomatic patients, as well as stage classification and monitoring disease progression and treatments. Furthermore, selective regulation of particular proteins targeting cancer cell proliferation, invasion, and apoptosis is a hopeful prospect for future anticancer therapy that slow disease progression and improve survival.

  • Snippet 1 (score: 0.424) > Endometrial cancer (EC) is the predominant form of gynecologic malignancy worldwide. The incidence of EC is approximately 142,000 women per year with an estimated 42,000 women dying from this disease. 1 There is currently a predominant role for surgical interventions in the management of patients without reproductive needs. 2 However, patients with elevated risk factors may require additional treatment techniques such as radiation and chemotherapy. These therapeutic approaches promote ROS-mediated stress and induce apoptosis in cancer cells. Cancer-related deficiencies in apoptosis initiation may occur, but there is also the possibility of an "oncogene addiction" phenomenon that can result in treatment ineffectiveness. 3 Cancer cells are exquisitely dependent upon a single oncogenic lesion through many genetic and epigenetic changes during the development of their neoplastic characteristics. It was found in a laboratory setting that tumor cells could depend on tumor cells when an oncogene was suppressed or tumor suppressor expression was restored, which led to the initial suggestion that the developemnt of tumor cells could depend on tumor cells. These first discoveries suggested that therapeutic drugs aimed at the repair or regulation of these mutant gene products might have broad effectiveness in the treatment of EC. Apoptosis, necroptosis and pyroptosis are discrete cellular mechanisms of programmed cell death within host cells. 4,5 7][18] In addition, pyroptosis plays a key role in the onset and advancement of several inflammatory conditions, particularly in the conversion of organ or cell inflammation into cancer. > The purpose of this study was to find, screen and evaluate information on inflammasomes and pyroptosis-dependent cell death in EC including information obtained from Elsevier, Google Scholar, PubMed, Science Direct, Scirus, Sci Finder, Scopus, Springer and Web of Science. We also identified potential therapeutic compounds that may be used to suggest and control these mechanisms. Furthermore, we used local and international books and peer-reviewed journals to find relevant information. This review also discusses the molecular mechanisms of pyroptosis-related signaling pathways and their contributory roles in the pathogenesis and progression of EC.

Although radiotherapy and chemotherapy improve patient survival, they are also associated with adverse effects and drug resistance [10]. In recent years, targeted therapies and immunotherapies have gradually become a research hotspot, and immune checkpoint inhibitors targeting the PD-1/PD-L1 pathway have demonstrated significant effectiveness in clinical trial [11]. For example, a clinical trial reported a 13% objective response rate (ORR) in patients with advanced endometrial cancer treated with pembrolizumab [12]. These emerging therapies present potential advancements in the prognosis of patients diagnosed with advanced endometrial cancer. This review aimed to reveal the molecular mechanisms underlying endometrial cancer and the profound impact of the immune microenvironment on disease progression and drug resistance. Recent studies have clearly indicated that various mechanisms are involved in drug resistance among endometrial cancer cells through aberrant activation of key signaling pathways, genetic mutation, and modification of the tumor microenvironment. We explored how these resistance mechanisms affect the efficacy of existing treatments, particularly targeted therapies and immunotherapies. Simultaneously, this study assessed recent advances in relevant therapeutic strategies and suggested the possibility of emerging therapeutic strategies to address the challenges posed by drug resistance. By systematically analyzing the progress of the current research, this study provides a solid theoretical foundation for clinical applications to promote the early diagnosis and individualized treatment of endometrial cancer.

  • Snippet 1 (score: 0.420) > To date, the p53 gene shows the closest relationship with human tumors. It is involved in regulating cell cycle, cell growth, apoptosis, and cell division. Tumor suppressor gene p53 is a transcription factor that can directly or indirectly control the cell cycle genes or apoptosis-related gene expression, and is involved in the apoptosis-related death receptor pathway and mitochondrial pathway [18,19]. Wild-type p53 protein plays a negative role in regulating cell growth. P53 mutation or abnormal expression is an important mechanism of inducing tumors [20]. P53 gene mutation may lead to loss of negative regulation, resulting in abnormal cell proliferation and canceration. This study analyzed p53 mRNA and protein, which are expressed in several common types of endometrial lesions. The results confirmed that p53 mRNA and protein levels in uterine adenomyosis were similar to those in controls. Its expression was significantly elevated in the endometrial polyps group and the endometrial adenocarcinoma group, especially in endometrial adenocarcinoma. Research showed that p53 gene and protein have important roles in the process of endometrial carcinoma. P53 gene activation and increased protein expression can induce abnormal cell proliferation. Its elevation can be seen in proliferative diseases, such as endometrial polyps and cancer. P53 gene mutation and abnormal protein expression often occur in the advanced stage of endometrial adenocarcinoma, and can assist diagnosing the degree of malignancy of endometrial cancer [15,21]. > The zinc finger structure in MDM2 can mediate protein interaction and the combination of DNA and RNA. It participates in regulating cell cycle and promoting cell proliferation, thus facilitating tumor growth [22,23]. However, little is known about MDM2 expression in various endometrial lesions, including uterine adenomyosis, endometrial polyps, and endometrial carcinoma. This study confirmed that MDM2 mRNA and protein expression showed no statistically significant differences between uterine adenomyosis and normal endometrium. Its level obviously increased in endometrial polyps and endometrial adenocarcinoma, particularly in the latter.

  • Evidence snippets:
  • Snippet 1 (score: 0.419) > Endometrial carcinoma (EC) is one of the most common gynecological cancer types, with increasing global incidence in recent years (1). A total of 60,050 cases of EC and 10,470 EC-associated cases of mortality were reported in the USA in 2016 (1), which was markedly higher than the 2012 statistics of 47,130 cases and 8,010 mortalities (2). Although numerous studies have been conducted to investigate the mechanisms of endometrial tumorigenesis and development, to the best of our knowledge, the exact etiology remains unknown. Understanding the potential molecular mechanisms underlying EC initiation and progression is of great clinical significance. Previously, microarray technologies and bioinformatics have widely been used for the differential expression analysis of cancer and healthy cells to identify novel diagnostic and therapeutic biomarkers (3). > MicroRNAs (miRNAs) are small, noncoding RNAs that regulate the expression of critical genes involved in cancer progression and treatment (4). They bind to the 3'-untranslated region (3'-UTR) of target mRNAs (5), resulting in either degradation or inhibition of the expression and function of protein-coding mRNAs. miRNAs regulate several functions in cancer cells, including proliferation, apoptosis, metastasis, immune evasion and differentiation (6). In addition, several miRNAs serve critical roles in EC pathogenesis (7,8) and are associated with clinicopathological features and survival (9). However, the specific mechanisms associated with miRNA-mediated regulation in EC require further investigation. > The current study evaluated the potential molecular mechanisms and biomarkers of EC using a bioinformatics approach. Microarray expression data were downloaded from the Gene Expression Omnibus (GEO) database and The Cancer Genome Atlas (TCGA). Differentially expressed genes (DEGs) and miRNAs (DEMs) in the EC samples compared with normal samples were identified using the GEO2R program and R software. The DEGs were subjected to functional and pathway enrichment analysis, followed by protein-protein interaction (PPI) network and survival analysis. A putative miRNA-mRNA network relevant to EC pathogenesis was then constructed.

  • Snippet 1 (score: 0.419) > As one of gynecologic tumors, endometrial carcinoma (EC) has been characterized by high incidence rate, but its molecular pathogenesis has remained unclear. TMED3 is a membrane protein and has been indicated to implicate several tumor-related diseases. In the current study, we aimed to explore the physiological function of TMED3 in EC progression. Through bioinformatic analysis using The Cancer Genome Atlas database and immunohistochemistry assay on tissue microarray, we examined whether TMED3 was upregulated in EC tissues. After constructing TMED3-knockdown cell models via lentiviral transfection, qPCR and western blot were employed to determine the expression levels of TMED3 mRNA and protein. Then, Celigo cell counting assay, CCK8 assay, flow cytometry, wound-healing assay and Transwell assay were used to detect cell proliferation, cell cycle, cell apoptosis and cell migration, respectively. As a result, it was found that TMED3 was upregulated in EC cells, which was also verified in clinical samples. We then found that downregulation of TMED3 considerably restrained cell cycle, cell growth and migration but promoted apoptosis of EC cells. The following in-vivo experiments also verified that tumor growth was inhibited after TMED3 knockdown. The exploration in molecular mechanisms showed that TMED3 deletion may weaken cellular viability through upregulating pro-apoptotic proteins and targeting PI3K/AKT signaling pathways. This study suggested that knocking down TMED3 affected the malignant phenotype of EC cells and thus limited tumor progression, which provided insights to the development of targeted drugs for EC treatment.
