Abstract
Gemcitabine plus cisplatin (GP) chemotherapy is the standard of care for nasopharyngeal carcinoma (NPC). However, the mechanisms underpinning its clinical activity are unclear. Here, using single-cell RNA sequencing and T cell and B cell receptor sequencing of matched, treatment-naive and post-GP chemotherapy NPC samples (n = 15 pairs), we show that GP chemotherapy activated an innate-like B cell (ILB)-dominant antitumor immune response. DNA fragments induced by chemotherapy activated the STING type-I-interferon-dependent pathway to increase major histocompatibility complex class I expression in cancer cells, and simultaneously induced ILB via Toll-like receptor 9 signaling. ILB further expanded follicular helper and helper type 1 T cells via the ICOSL-ICOS axis and subsequently enhanced cytotoxic T cells in tertiary lymphoid organ-like structures after chemotherapy that were deficient for germinal centers. ILB frequency was positively associated with overall and disease-free survival in a phase 3 trial of patients with NPC receiving GP chemotherapy ( NCT01872962 , n = 139). It also served as a predictor for favorable outcomes in patients with NPC treated with GP and immunotherapy combined treatment (n = 380). Collectively, our study provides a high-resolution map of the tumor immune microenvironment after GP chemotherapy and uncovers a role for B cell-centered antitumor immunity. We also identify and validate ILB as a potential biomarker for GP-based treatment in NPC, which could improve patient management.

Abstract
Cancer is an important factor threatening human life and health; in recent years, its morbidity and mortality remain high and demosntrate an upward trend. It is of great significance to study its pathogenesis and targeted therapy. As the complex mechanisms of epigenetic modification has been increasingly discovered, they are more closely related to the occurrence and development of cancer. As a reversible response, epigenetic modification is of great significance for the improvement of classical therapeutic measures and the discovery of new therapeutic targets. It has become a research focusto explore the multi-level mechanisms of RNA, DNA, chromatin and proteins. As an important means of cancer treatment, radiotherapy has made great progress in technology, methods, means and targeted sensitization after years of rapid development, and even research on radiotherapy based on epigenetic modification is rampant. A series of epigenetic effects of radiation on DNA methylation, histone modification, chromosome remodeling, RNA modification and non-coding RNA during radiotherapy affects the therapeutic effects and prognosis. Starting from the epigenetic mechanism of tumorigenesis, this paper reviews the latest progress in the mechanism of interaction between epigenetic modification and cancer radiotherapy and briefly introduces the main types, mechanisms and applications of epigenetic modifiers used for radiotherapy sensitization in order to explore a more individual and dynamic approach of cancer treatment based on epigenetic mechanism. This study strives to make a modest contribution to the progress of human disease research.

Abstract
BACKGROUND In the past 2 decades, metastasis-associated gene 1 (MTA1) has attracted attention for its close association with cancer progression and its roles in chromatin remodeling processes, making it a central gene in cancer. The present meta-analysis was performed to assess MTA1 expression in solid tumors. MATERIALS AND METHODS This analysis identified studies that evaluated the relationship between MTA1 expression and clinical characteristics or prognosis of patients with solid tumors via the PubMed, Cochrane Library, and Embase electronic databases. Fixed-effect and random-effect meta-analytical techniques were used to correlate MTA1 expression with outcome measures. The outcome variables are shown as odds ratio (OR) or hazard ratio (HR) with 95% confidence interval (CI). RESULTS Analysis of 40 cohort studies involving 4564 cancer patients revealed a significant association of MTA1 overexpression with tumor patient age (>50 vs. <50 years: combined OR 0.73, 95% CI 0.57-0.94), tumor grade (G3/4 vs. G1/2: combined OR 1.94, 95% CI 1.48-2.53), tumor size (>3 cm vs. <3 cm: combined OR 2.35, 95% CI 1.73-3.19), T stage (T3/4 vs. T1/2: combined OR 2.11, 95% CI 1.74-2.56), lymph node metastasis (yes vs. no: combined OR 2.92, 95% CI 2.26-3.75), distant metastasis (yes vs. no: combined OR 2.26, 95% CI 1.42-3.59), TNM stage (III/IV vs. I/II: combined OR 2.50, 95% CI 1.84-3.38), vascular invasion (yes vs. no: combined OR 2.26, 95% CI 1.92-3.56), and poor overall survival time (HR 1.83; 95% CI: 1.53-2.20; P = .000). CONCLUSIONS Our analyses demonstrate that MTA1 was an effective predictor of a worse prognosis in tumor patients. Moreover, MTA1 may play important role in tumor progression and outcome, and targeting MTA1 may be a new strategy for anti-cancer therapy.

Abstract
The metastasis-associated gene 1 (MTA1) has previously been recognized as an oncogene, and abnormal MTA1 expression has been related to progression of numerous cancer types to the metastasis stage. However, the function of MTA1 in the regulation of pancreatic cancer progression and metastasis remains unclear. Western blot analysis was adopted to determine the expression of MTA1 in pancreatic cancer tissues and corresponding near normal tissues. Steady clone with MTA1-overexpression and MTA1-inhibitionweregenerated via lentivirus technology in BxPc-3 cells. Transwell assay was carried out for detecting the invasion of pancreatic cancer cells. The migration activity was assessed using the wound scratch assay. The effect of MTA1 in pancreatic cancer was evaluated in the mice xenografts. Western blot analysis was employed to determine the expression of hypoxia inducible factor-α (HIF-α) and vascular endothelial growth factor (VEGF) in vitro and in vivo. We observed that MTA1 overexpression enhanced migration and invasion ability of pancreatic cancer cells in vitro and increased HIF-α and VEGF protein levels in vitro and in vivo. MTA1 inhibition had the opposite effects. MTA1 protein level was positively related to HIF-α and VEGF protein levels. These results indicated that MTA1 potentially promoted pancreatic cancer metastasis via HIF-α/VEGF pathway. This research supplies a new molecular mechanism for MTA1 in the pancreatic cancer progression and metastasis. MTA1 may be an effective therapy target in pancreatic cancer.

Abstract
The aim of this study was to elaborate the correlation between metastasis-associated protein (MTA) family and the occurrence, progression, prognosis and chemotherapy efficiency in nasopharyngeal carcinoma (NPC).The expression of MTA1, MTA2 and MTA3 protein were detected by immunohistochemistry in a tissue microarray (TMAs) which contains tissue samples of 152 NPC patients embedded by formalin-fixed paraffin. The MTA proteins were mainly expressed in the nuclei of NPC tissues and the correlations between MTAs expression and clinical parameters as well as prognosis of NPC patients showed ethnical differences according to statistically analysis. The results showed that in Han ethnic group, MTA1 expression was positively correlated with N staging, while the expression of MTA2 was negatively correlated with age, and the expression of MTA3 was positively correlated with gender. Patients with high MTA1 expression had poorprognosis. In Zhuang ethnic group, only MTA3 expression was positively correlated with age, recurrence and metastasis of NPC patients; neither MTA1 nor MTA2 expression had any correlation with clinical indexes. Patients with high MTA3 expression had unfavorable prognosis. In addition, our results showed that overall survival among Zhuang NPC patients with low expression of MTA2 increased significantly owing to "carboplatin + fluorouracil" chemotherapy. This therapeutic success, however, did not translate to longer overall survival among Han NPC patients. The biological function of MTA protein family in NPC patients was different among different ethnic groups. In conclusion, we demonstrated that MTAs had a certain tumor promoting function in patients with NPC, and the biological functions of MTAs might be ethnic differences, which suggesting MTAs to be important markers for guiding clinical treatment of NPC.

Abstract
MicroRNA 183 (miR-183) was identified to be downregulated in nasopharyngeal carcinoma spheroids and served as a tumor suppressor in nasopharyngeal carcinoma. However, the regulatory mechanism of miR-183 and its role in cisplatin (DDP) resistance in nasopharyngeal carcinoma cells are still unclear. The expression of miR-183 and metastasis-associated protein 1 at messenger RNA and protein levels in nasopharyngeal carcinoma tissues and cells was evaluated using quantitative reverse transcription real-time polymerase chain reaction and western blotting, respectively. CNE1 and CNE2 cells were transfected with miR-183 mimic, miR-183 inhibitor, pcDNA-metastasis-associated protein 1, or respective controls. The effects of miR-183 and metastasis-associated protein 1 overexpression on cell proliferation, invasion, and DDP-induced apoptosis were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, Transwell invasion assay, and flow cytometry analysis, respectively. Luciferase reporter assay was performed to explore whether miR-183 directly targeted metastasis-associated protein 1. Xenograft tumor experiment was applied to confirm the biological function of miR-183 in vivo. MiR-183 was downregulated in nasopharyngeal carcinoma tissues and cells and negatively correlated with metastasis-associated protein 1 expression. Ectopic expression of miR-183 markedly suppressed cell proliferation and invasion and strikingly enhanced DDP-induced apoptosis in nasopharyngeal carcinoma cells, whereas metastasis-associated protein 1 overexpression partially reversed these effects. Luciferase reporter assay demonstrated that metastasis-associated protein 1 was a direct target of miR-183. MiR-183 negatively regulated the expression of metastasis-associated protein 1 at both the messenger RNA and protein levels. Xenograft tumor experiment indicated that miR-183 overexpression repressed tumor growth and improved DDP-induced cytotoxicity in nasopharyngeal carcinoma cells in vivo. MiR-183 overexpression inhibited tumorigenesis and enhanced DDP-induced cytotoxicity by targeting metastasis-associated protein 1 in nasopharyngeal carcinoma, contributing to the development of novel therapeutic approaches for the treatment of clinical nasopharyngeal carcinoma patients.

Abstract
The metastasis-associated (MTA) gene family is a critical component of the nucleosome remodeling and histone deacetylase complex, and plays an important role in metastatic processes. We systematically evaluated dysregulation of the MTA family to clarify their clinical significance in gastric cancer (GC). One hundred and forty-five patients who underwent surgery for GC were evaluated. We analyzed the expression levels of the MTA family (MTA1, 2 and 3) by qPCR in GC tissue, and the MTA1 protein expression in primary cancer and matched normal mucosa (NM) was measured using immunohistochemical analysis. The expression of all the MTA family members was significantly increased in a stage-dependent manner, and elevated expression of all of the MTA family members was correlated with metastatic factors and prognosis in GC patients. Multivariate analysis revealed that MTA1 overexpression was an independent risk factor for survival. Especially, elevated expression of MTA1 was significantly correlated with recurrence, and was an independent risk factor for lymph node metastasis. Immunohistochemical analysis demonstrated that MTA1 was predominantly expressed in the nuclei of primary GC cells but was not expressed in NM and in the cancer stroma. In conclusion, quantification of MTA expression may support the accurate diagnosis of disease staging and may help predict clinical outcomes.

Epigenomic regulation of oncogenesis by chromatin remodeling. Oncogene 2016; 35:4423-36.

Abstract
Disruption of the intricate gene expression program represents one of major driving factors for the development, progression and maintenance of human cancer, and is often associated with acquired therapeutic resistance. At the molecular level, cancerous phenotypes are the outcome of cellular functions of critical genes, regulatory interactions of histones and chromatin remodeling complexes in response to dynamic and persistent upstream signals. A large body of genetic and biochemical evidence suggests that the chromatin remodelers integrate the extracellular and cytoplasmic signals to control gene activity. Consequently, widespread dysregulation of chromatin remodelers and the resulting inappropriate expression of regulatory genes, together, lead to oncogenesis. We summarize the recent developments and current state of the dysregulation of the chromatin remodeling components as the driving mechanism underlying the growth and progression of human tumors. Because chromatin remodelers, modifying enzymes and protein-protein interactions participate in interpreting the epigenetic code, selective chromatin remodelers and bromodomains have emerged as new frontiers for pharmacological intervention to develop future anti-cancer strategies to be used either as single-agent or in combination therapies with chemotherapeutics or radiotherapy.

Abstract
Since the initial recognition of the metastasis-associated protein 1 (MTA1) as a metastasis-relevant gene approximately 20 years ago, our appreciation for the complex role of the MTA family of coregulatory proteins in human cancer has profoundly grown. MTA proteins consist of six family members with similar structural units and act as central signaling nodes for integrating upstream signals into regulatory chromatin-remodeling networks, leading to regulation of gene expression in cancer cells. Substantial experimental and clinical evidence demonstrates that MTA proteins, particularly MTA1, are frequently deregulated in a wide range of human cancers. The MTA family governs cell survival, the invasive and metastatic phenotypes of cancer cells, and the aggressiveness of cancer and the prognosis of patients with MTA1 overexpressing cancers. Our discussion here highlights our current understanding of the regulatory mechanisms and functional roles of MTA proteins in cancer progression and expands upon the potential implications of MTA proteins in cancer biology and cancer therapeutics.

Abstract
Background Talin-1 is a cytoskeletal protein that plays an important role in tumourgenesis, migration and metastasis in several malignant tumors. The aim of this study was to evaluate the expression and prognostic value of Talin-1 in nasopharyngeal carcinoma (NPC). Methods Talin-1 mRNA and protein expression were examined in NPC cell lines and clinical nasopharyngeal tissues by quantitative RT-PCR, agarose gel electrophoresis and western blotting. The expression of Talin-1 was analyzed by immunohistochemical staining in 233 paraffin-embedded NPC specimens with clinical follow-up data and cox regression analysis was used to identify independent prognostic factors. The functional role of Talin-1 in NPC cell lines was evaluated by small interfering RNA-mediated depletion of the protein followed by the wound healing and transwell invasion assays. Results The expression of Talin-1 was significantly upregulated in most NPC cell lines and clinical tissues at both the mRNA and protein levels. High expression of Talin-1 was significantly associated with distant metastasis (P = 0.001) and patient death (P = 0.001). In addition, high expression of Talin-1 was associated with significantly poorer overall survival (OS: HR, 2.15; 95% CI, 1.28-3.63; P = 0.003) and poorer distant metastasis-free survival (DMFS: HR, 2.39; 95% CI, 1.38-4.15; P = 0.001). Cox regression analysis indicated that high expression of Talin-1 and TNM stage were independent prognostic indicators (both P < 0.05). Stratified analysis demonstrated that high expression of Talin-1 was associated with significantly poorer survival in patients with advanced stage disease (stage III-IV, HR, 1.91; 95% CI, 1.09-3.35; P = 0.02 for OS and HR, 2.22; 95% CI, 1.24-3.99; P = 0.006 for DMFS). Furthermore, the depletion of Talin-1 suppressed the migratory and invasive ability of NPC cells in vitro. Conclusions Our data demonstrate that high expression of Talin-1 is associated with significantly poorer OS and poorer DMFS in NPC and depletion of Talin-1 expression inhibited NPC cell migration and invasion. Talin-1 may serve as novel prognostic biomarker in NPC.

Abstract
The members of the metastasis-associated protein (MTA) family play pivotal roles in both physiological and pathophysiological processes, especially in cancer development and metastasis, and their role as master regulators has come to light. Due to the fact that they were first identified as crucial factors in estrogen receptor-mediated breast cancer metastasis, most of the early studies focused on their hormone-dependent functions. However, the accumulating evidence shows that the members of MTA family are deregulated in most, if not all, the cancers studied so far. Therefore, the levels as well as the activities of the MTA family members are widely accepted as potential biomarkers for diagnosis, prognosis, and predictors of overall survival. They function differently in different cancers with specific mechanisms. p53 and HIF-1α appear to be the respectively common upstream and downstream regulator of the MTA family in both development and metastasis of a wide spectrum of cancers. Here, we review the expression and clinical significance of the MTA family, focusing on hormone-independent cancers. To illustrate the molecular mechanisms, we analyze the MTA family-related signaling pathways in different cancers. Finally, targeting the MTA family directly or the pathways involved in the MTA family indirectly could be invaluable strategies in the development of cancer therapeutics.

Abstract
Among the genes that were found to be abundantly overexpressed in highly metastatic rat cell lines compared to poorly metastatic cell lines, we identified a completely novel complementary DNA (cDNA) without any homologous or related genes in the database in 1994. The full-length cDNA of this rat gene was cloned, sequenced, and named metastasis-associated gene 1 (mta1), and eventually, its human cDNA counterpart, MTA1, was also cloned and sequenced by our group. MTA1 has now been identified as one of the members of a gene family (MTA gene family) and the products of the MTA genes, the MTA proteins, are transcriptional co-regulators that function in histone deacetylation and nucleosome remodeling and have been found in nuclear histone remodeling complexes. Furthermore, MTA1 along with its protein product MTA1 has been repeatedly and independently reported to be overexpressed in a vast range of human cancers and cancer cell lines compared to non-cancerous tissues and cell lines. The expression levels of MTA1 correlate well with the malignant properties of human cancers, strongly suggesting that MTA1 and possibly other MTA proteins (and their genes) could be a new class of molecular targets for cancer diagnosis and therapy.

Abstract
Head and neck cancers usually originate in the squamous cells that line the inner mucosal surfaces of the oral and the neck region. These cancers follow multifocal steps for progression that include risk of developing metastasis. Although therapeutics has advanced in the past decades, head and neck cancers continue to cause much morbidity and mortality. Even with the promising effect of targeted therapies, there is a need for a better evaluation of patients with head and neck cancers. Metastasis-associated tumour antigen 1 (MTA1), a chromatin modifier, is found as an integral part of nucleosome remodelling and histone deacetylation (NuRD) complex. MTA1 is a biomarker for several solid tumours, and the overexpression of which have been documented in various cancers such as breast, ovarian, colon, prostrate etc. Interestingly also, a set of head and neck cancers shows MTA1 overexpression. However, recent evidences from clinical data raise a critical question on the role of MTA1 in head and neck cancers. This calls for a detailed review to the role of MTA1 in oral cancer. This review gives a brief account on the existing biological and molecular data in the context of head and neck cancer invasion and metastasis in relation to MTA1.

Abstract
Metastasis-associated protein 1 (MTA1) is related to tumour metastasis and poor prognosis in various human cancers. The aim of this study was to investigate the expression of MTA1 in nasopharyngeal carcinoma (NPC) and explore the prognostic value of MTA1 in NPC patients. The expression of MTA1 in 136 human NPC tissues and 20 normal nasopharyngeal tissues was detected using immunohistochemistry, quantified and classified into low or high expression using a 50% cut-off level. The relationships of MTA1 expression with the clinical characteristics and survival of patients were analysed. MTA1-positive staining was observed in the nuclei of NPC cells, and MTA1 expression was significantly correlated with T stage (P = 0.006), clinical stage (P = 0.001) and distant metastasis (P < 0.001). Patients with high MTA1 expression exhibited significantly worse distant metastasis-free survival (DMFS) than those with low MTA1 expression (90.75% vs. 70.81%, P = 0.017). Multivariate survival analysis revealed that MTA1 expression was an independent prognostic factor for DMFS (P = 0.038). In this study, high MTA1 expression was significantly associated with poor DMFS in NPC, indicating that MTA1 could serve as a novel biomarker for assessing the metastatic potential of NPC and could act as a possible therapeutic target for the treatment of metastatic nasopharyngeal carcinoma.

Abstract
The subcellular localization of a protein is closely linked to and indicates its function. The metastatic tumor antigen (MTA) family has been under continuous investigation since its identification two decades ago. MTA1, MTA2, and MTA3 are the main members of the MTA family. MTA1, as the representative member of this family, has been shown to be widely expressed in both embryonic and adult tissues, as well as in normal and cancerous conditions, indicating that MTA1 has functions both in physiological and pathological contexts. MTA1 is expressed at a higher level in most cancers than in their normal tissue counterparts. Even in normal cells, MTA1 levels vary a great deal from tissue to tissue. Importantly, MTA1 shows a multiple localization pattern in the cell, as do MTA2 and MTA3. Different MTA components in different subcellular compartments may exert different molecular functions in the cell. Previous studies revealed that MTA1 and MTA2 are predominately localized to the nucleus, while MTA3 is observed in both the nucleus and cytoplasm. Recent studies have reported that MTA1 is located in the nucleus, cytoplasm, and the nuclear envelope. In the nucleus, MTA1 dynamically interacts with chromatin in a MTA1-K532 methylation-dependent manner, whereas cytoplasmic MTA1 binds to the microtubule skeleton. MTA1 also shows a dynamic distribution during the cell cycle. Further investigations are needed to identify the exact subcellular localizations of MTA proteins. We review the sub-cellular localization patterns of the MTA family members and give a comprehensive overview of their respective molecular activities in multiple contexts.

J Virol 2014; 88:11872-85. [PMID: 25100829 PMCID: PMC4178752 DOI: 10.1128/jvi.01867-14] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2014] [Accepted: 07/14/2014] [Indexed: 11/20/2022] Open
Abstract
Epstein-Barr virus-encoded latent membrane protein 2A (LMP2A) promotes the epithelial-mesenchymal transition (EMT) of nasopharyngeal carcinoma (NPC), thereby increasing tumor invasion. Recently, the dysregulation of metastatic tumor antigen 1 (MTA1) was found to enhance tumor metastasis in a variety of cancers. A molecular connection between these two proteins has been proposed but not firmly established. In this study, we reported the overexpression of MTA1 in 29/60 (48.3%) NPC patients, and the overexpression of MTA1 significantly correlated with tumor metastasis. The overexpression of MTA1 promoted EMT via the Wnt1 pathway and β-catenin activation. We demonstrated that LMP2A reinforces the expression of MTA1 via the mechanistic target of rapamycin (mTOR) pathway to promote EMT in NPC. Furthermore, by knocking down 4EBP1 in combination with the new mTOR inhibitor INK-128 treatment, we discovered that LMP2A expression activates the 4EBP1-eIF4E axis and increases the expression of MTA1 at the translational level partially independent of c-myc. These findings provided novel insights into the correlation between the LMP2A and MTA1 proteins and reveal a novel function of the 4EBP1-eIF4E axis in EMT of nasopharyngeal carcinoma. Importance: Prevention of the recurrence and metastasis of NPC is critical to achieving a successful NPC treatment. As we all know, EMT has a vital role in metastasis of malignancies. LMP2A, an oncoprotein of Epstein-Barr virus, a well-known NPC activator, induces EMT and has been proved to exert a promoting effect in tumor metastasis. Our study demonstrated that LMP2A could induce EMT by activating MTA1 at the translational level via activating mTOR signaling and the 4EBP1-eIF4E axis. Taken together, our findings bridge the gap between the NPC-specific cell surface molecule and the final phenotype of the NPC cells. Additionally, our findings indicate that LMP2A and mTOR will serve as targets for NPC therapy in the future.

Abstract
Metastasis-associated protein 1 (MTA1) is a molecular marker in various solid tumors that has recently been investigated. The prognostic significance of MAT1 expression remains controversial. In this work, we aimed to determine the relationship between immunohistochemistry-detected MAT1 expression and survival of patients with solid tumors by conducting a meta-analysis of cohort studies. Relevant studies were identified via an electronic database search updated on October 28, 2013. We included cohort studies that reported hazard ratios (HRs) or odds ratios (ORs) with 95 % confidence intervals (CIs) to determine the association of high MTA1 expression with overall survival (OS) and clinicopathological characteristics. Heterogeneity was quantified using I (2) statistics, and publication bias was evaluated using funnel plots. Sensitivity analysis was conducted to evaluate the robustness of meta-analysis findings. We identified 16 cohort studies that focused on MTA1 overexpression and prognosis involving 2,253 cancer patients. Overall, the combined HR for OS was 1.85 (95 % CI: 1.55-2.28, P<0.001). Omission of any single study had no significant effect on the pooled HR estimate. When the studies were stratified by tumor type, similar results of poor prognosis were observed in non-small cell lung cancer (HR=2.05, 95 % CI: 1.14-3.68, P=0.016) and esophageal squamous cell carcinoma (HR=1.86, 95 % CI: 1.44-2.39, P<0.001). Moreover, multivariate survival analysis showed that MTA1 overexpression was an independent predictor of poor prognosis (HR=1.90, 95 % CI: 1.53-2.37, P<0.001). In addtional, MTA1 overexpression was significantly associated with tumor size (OR=2.72, 95 % CI=1.44-5.14, P=0.002), tumor stage (OR=2.44, 95 % CI=1.67-3.57, P<0.001), depth of invasion (OR=2.63, 95 % CI=1.74-3.97, P<0.001), and lymph node metastasis (OR=2.57, 95 % CI=1.57-4.19, P<0.001). However, when age, sex, and tumor differentiation were considered, no obvious association was observed. This study provides a comprehensive examination of the literature available on the association of MTA1 overexpression with OS and some clinicopathological features in solid tumors. Meta-analysis results provide evidence that MTA1 may be a new indicator of poor cancer prognosis. Considering the limitations of the eligible studies, other large-scale prospective trials must be conducted to clarify the prognostic value of MTA1 in predicting cancer survival.

Abstract
Metastasis-associated gene 1 (MTA1), which is involved in tumor progression, metastasis, and angiogenesis, has been examined in several malignant tumors. However, the expression and the effect of MTA1 on human cervical cancer remain unknown. In this study, we investigated the level of MTA1 expression in cervical carcinoma and its clinical significance. By immunohistochemical staining, the correlation of MTA1 overexpression with clinical features and patient outcome was analyzed in 132 formalin-fixed, paraffin-embedded cervical cancer tissues. MTA1 protein overexpression was detected in 73 (55.3%) of 132 patients. High levels of MTA1 protein were clearly correlated with histologic grade (P = .006), lymph node metastasis (P = .001), and recurrence (P = .016). Multivariate Cox analysis showed that MTA1 was an independent factor for overall survival (hazard ratio, 3.486; 95% confidence interval [CI], 1.274-9.537; P = .015) and disease-free survival (hazard ratio, 3.373; 95% CI, 1.212-9.387; P = .020). Multivariate logistic regression analysis indicated that elevated MTA1 was strongly associated with lymph node metastasis (odds ratio, 3.879; 95% CI, 1.391-10.816; P = .010). Sensitivity and specificity were calculated as 81.25% and 53.0%, respectively. These findings suggest that MTA1 nuclear overexpression is associated with tumor progression and metastasis and thus support its clinical significance in future gene-targeted therapies, particularly the management of patients with cervical cancer.

Abstract
BACKGROUND The prognostic value of metastasis-associated gene 1 (MTA1) in nasopharyngeal carcinoma (NPC) has been suggested. However, there is still no direct evidence that MTA1 promotes NPC growth in vivo. In this study, we aimed to investigate the function of MTA1 in the regulation of NPC cell proliferation and tumorigenesis in vitro and in vivo. METHODS Stable MTA1 knockdown or overexpression NPC cell lines were employed. The effects of MTA1 depletion or overexpression on cell proliferation, colony formation, cell cycle progression were examined by MTT, colony formation and flow cytometry assay. The effects of MTA1 depletion on tumor growth in vivo were examined in mouse xenograft model. RESULTS MTA1 knockdown or overexpression drastically changed the proliferation, colony formation and cell cycle of NPC cells in vitro. MTA1 depletion significantly suppressed NPC tumorigenesis in vivo. CONCLUSION MTA1 promotes NPC cell proliferation via enhancing G1 to S phase transition, leading to increased tumor growth. Targeting MTA1 is a promising approach to reduce tumor burden of NPC.

Abstract
Nasopharyngeal carcinoma (NPC) is prone to appearing regional lymph node and distant metastasis. And its underlying mechanism is unclear. Recent study suggests that overexpression of metastasis-associated gene 1 (MTA1) was independently associated with poorer distant metastasis-free survival in NPC. However, it is still lack of direct evidence that MTA1 is responsible for aggressive phenotypes of NPC. Using stably transfected MTA1 knockdown or overexpression cells, we discovered the function of MTA1 in actin cytoskeleton reorganization and metastasis processing of NPC in this study. For the first time, our data demonstrate two tumor relevant molecular mechanisms, i.e. Rho GTPases and Hedgehog signaling both contribute to the effect of MTA1 on the aggressive phenotypes of NPC cells. In summary, the novel findings in this work provide further insight into the function of MTA1 and the molecular mechanism in the progression of NPC. Our results indicate that MTA1 might serve as a potential therapeutic target for advanced NPC.
