Abstract
Pancreatic cancer (PC), as one of the main endocrine and digestive systems malignancies has the highest cancer related mortality in the world. Lack of the evident clinical symptoms and appropriate diagnostic markers in the early stages of tumor progression are the main reasons of the high mortality rate among PC patients. Therefore, it is necessary to investigate the molecular pathways involved in the PC progression, in order to introduce novel early diagnostic methods. Epithelial mesenchymal transition (EMT) is a critical cellular process associated with pancreatic tumor cells invasion and distant metastasis. MicroRNAs (miRNAs) are also important regulators of EMT process. In the present review, we discussed the role of miRNAs in regulation of EMT process during PC progression. It has been reported that the miRNAs mainly regulate the EMT process in pancreatic tumor cells through the regulation of EMT-specific transcription factors and several signaling pathways such as WNT, NOTCH, TGF-β, JAK/STAT, and PI3K/AKT. Considering the high stability of miRNAs in body fluids and their role in regulation of EMT process, they can be introduced as the non-invasive diagnostic markers in the early stages of malignant pancreatic tumors. This review paves the way to introduce a non-invasive EMT based panel marker for the early tumor detection among PC patients.

Moghaddam ST, Forghanifard MM. Clinicopathological relevance of stem cell marker growth and differentiation factor 3 in esophageal squamous cell carcinoma. EXPLORATION OF TARGETED ANTI-TUMOR THERAPY 2023; 4:217-226. [PMID: 37205315 PMCID: PMC10185436 DOI: 10.37349/etat.2023.00130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Accepted: 01/17/2023] [Indexed: 05/21/2023] Open
Abstract
Esophageal squamous cell carcinoma (ESCC) is the second leading cause of cancer-related deaths in Iran, often diagnosed in advanced stages with a poor prognosis. Growth and differentiation factor 3 (GDF3) is a member of the transforming growth factor-beta (TGF-β) superfamily. It acts as an inhibitor of bone morphogenetic proteins (BMPs) signaling pathway associated with pluripotent embryonic and cancer stem cells (CSCs) characteristics. Since its expression in ESCC has not yet been evaluated, the clinicopathological relevance of GDF3 expression was elucidated in ESCC patients. Expression of GDF3 in tumor tissues from 40 ESCC patients was compared to the related margin normal tissues by relatively comparative real-time polymerase chain reaction (PCR). Glyceraldehydes 3-phosphate dehydrogenase (GAPDH) was used as the endogenous control. Likewise, the function of GDF3 in the differentiation and development of embryonic stem cells (ESCs) was also reviewed. GDF3 was significantly overexpressed in 17.5% of tumors and a significant correlation between GDF3 expression and the depth of tumor invasion was observed (P = 0.032). The results suggest that GDF3 expression is likely to have substantial roles in the progression and invasiveness behavior of ESCC. Having considered the importance of CSC markers identification and their exploitation in targeted cancer therapy, GDF3 may be introduced as a promising therapeutic target to inhibit the invasion of tumor cells in ESCC.

Abstract
Bladder cancer (BC) is the 11th most popular cancer in females and 4th in males. A lot of efforts have been exerted to improve BC patients' care. Besides, new approaches have been developed to enhance the efficiency of BC diagnosis, prognosis, therapeutics, and monitoring. MicroRNAs (miRNAs, miRs) are small chain nucleic acids that can regulate wide networks of cellular events. They can inhibit or degrade their target protein-encoding genes. The miRNAs are either downregulated or upregulated in BC due to epigenetic alterations or biogenesis machinery abnormalities. In BC, dysregulation of miRNAs is associated with cell cycle arrest, apoptosis, proliferation, metastasis, treatment resistance, and other activities. A variety of miRNAs have been related to tumor kind, stage, or patient survival. Besides, although new approaches for using miRNAs in the diagnosis, prognosis, and treatment of BC have been developed, it still needs further investigations. In the next words, we illustrate the recent advances in the role of miRNAs in BC aspects. They include the role of miRNAs in BC pathogenesis and therapy. Besides, the clinical applications of miRNAs in BC diagnosis, prognosis, and treatment are also discussed.

Cancers (Basel) 2023; 15:cancers15030621. [PMID: 36765579 PMCID: PMC9913674 DOI: 10.3390/cancers15030621] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 01/02/2023] [Accepted: 01/16/2023] [Indexed: 01/20/2023] Open
Abstract
PURPOSE To assess the mechanism of EPH receptor A3 (EPHA3) and its potential value for immunotherapy in BLCA. MATERIALS AND METHODS The Cancer Genome Atlas (TCGA) bladder cancer (BLCA) database and the Gene Expression Omnibus (GEO) database were used for assessing whether EHPA3 could be used to predict BLCA prognosis. This work carried out in vitro and in vivo assays for exploring how EPHA3 affected the biological behaviors. The downstream pathway was explored using a Western blotting technique. The CIBERSORT, ESTIMATE, TIMER, and TIDE tools were used to predict the immunotherapy value of EPHA3 in BLCA. RESULTS EPHA3 was poorly expressed in BLCA (p < 0.05), its high expression is related to a good survival prognosis (p = 0.027 and p = 0.0275), and it has a good predictive ability for the histologic grade and status of BLCA (area under curve = 0.787 and 0.904). Overexpressed EPHA3 could inhibit BLCA cell biological behaviors, and it be associated with the downregulation of the Ras/pERK1/2 pathway. EPHA3 was correlated with several immune-infiltrating cells and the corresponding marker genes. CONCLUSIONS EPHA3 could be regarded as an acceptable anti-cancer biomarker in BLCA. EPHA3 plays an inhibiting role in BLCA, and it could be the candidate immunotherapeutic target for BLCA.

Abstract
BACKGROUND Biomarkers to predict the risk of disease recurrence in Esophageal squamous cell carcinoma (ESCC) patients are urgently needed to improve treatment. We developed proteins expression-based risk model to predict recurrence free survival for ESCC patients. METHODS Alterations in Wnt pathway components expression and subcellular localization were analyzed by immunohistochemistry in 80 ESCCs, 61 esophageal dysplastic and 47 normal tissues; correlated with clinicopathological parameters and clinical outcome over 86 months by survival analysis. Significant prognostic factors were identified by multivariable Cox regression analysis. RESULTS Biomarker signature score based on cytoplasmic β-catenin, nuclear c-Myc, nuclear DVL and membrane α-catenin was associated with recurrence free survival [Hazard ratio = 1.11 (95% CI = 1.05, 1.17), p < 0.001, C-index = 0.68] and added significant prognostic value over clinical parameters (p < 0.001). The inclusion of Slug further improved prognostic utility (p < 0.001, C-index = 0.71). Biomarker Signature Scoreslug improved risk classification abilities for clinical outcomes at 3 years, accurately predicting recurrence in 79% patients in 1 year and 97% in 3 years in high risk group; 73% patients within low risk group did not have recurrence in 1 year, with AUC of 0.76. CONCLUSIONS Our comprehensive risk model predictive for recurrence allowed us to determine the robustness of our biomarker panel in stratification of ESCC patients at high or low risk of disease recurrence; high risk patients are stratified for more rigorous personalized treatment while the low risk patients may be spared from harmful side effects of toxic therapy.

Abstract
Lung cancer is the second most common and the leading cause of cancer related deaths globally. Tyrosine Kinase Inhibitors (TKIs) are among the common therapeutic strategies in lung cancer patients, however the treatment process fails in a wide range of patients due to TKIs resistance. Given that the use of anti-cancer drugs can always have side effects on normal tissues, predicting the TKI responses can provide an efficient therapeutic strategy. Therefore, it is required to clarify the molecular mechanisms of TKIs resistance in lung cancer patients. MicroRNAs (miRNAs) are involved in regulation of various pathophysiological cellular processes. In the present review, we discussed the miRNAs that have been associated with TKIs responses in lung cancer. MiRNAs mainly exert their role on TKIs response through regulation of Tyrosine Kinase Receptors (TKRs) and down-stream signaling pathways. This review paves the way for introducing a panel of miRNAs for the prediction of TKIs responses in lung cancer patients. Video Abstract

Abstract
Abstract
Background
Bladder cancer (BCa) and prostate cancer (PCa) are frequent urothelial and genital malignancies with a high ratio of morbidity and mortality which are more common among males. Since BCa and PCa cases are mainly diagnosed in advanced stages with clinical complications, it is required to introduce the efficient early detection markers. Protein kinases are critical factors involved in various cellular processes such as cell growth, motility, differentiation, and metabolism. Deregulation of protein kinases can be frequently observed through the neoplastic transformation and tumor progression. Therefore, kinases are required to be regulated via different genetic and epigenetic processes. MicroRNAs (miRNAs) are among the critical factors involved in epigenetic regulation of protein kinases. Since miRNAs are noninvasive and more stable factors in serum and tissues compared with mRNAs, they can be used as efficient diagnostic markers for the early detection of PCa and BCa.
Main body
In present review, we have summarized all of the reported miRNAs that have been associated with regulation of protein kinases in bladder and prostate cancers.
Conclusions
For the first time, this review highlights the miRNAs as critical factors in regulation of protein kinases during prostate and bladder cancers which paves the way of introducing a noninvasive kinase-specific panel of miRNAs for the early detection of these malignancies. It was observed that the class VIII receptors of tyrosine kinases and non-receptor tyrosine kinases were the most frequent targets for the miRNAs in bladder and prostate cancers, respectively.

Abstract
PURPOSE Esophageal squamous cell carcinoma (ESCC) is categorized among ten common aggressive malignancies, with a higher incidence and mortality rates in the developing than in developed countries. The inositol polyphosphate 5-phosphatase (INPP5A), as an intracellular-calcium mobilizer and modifier enzyme, facilitates cell responses to various stimuli. Epithelial-mesenchymal transition (EMT), a transformation procedure, has a vital role in cancer progression and metastasis when epithelial cells lose their traits in favor of obtaining mesenchymal features. In this study, we analyzed the correlation between the expression of INPP5A and the involved genes in EMT pathway through the progression and development of the ESCCs. MATERIALS AND METHODS The gene expression analyses of INPP5A, TWIST1, MMP-2, and EGFR were performed using relative comparative real-time PCR in 58 ESCCs patients compared to corresponding margin-normal esophageal tissues. RESULTS A significant inverse correlation between INPP5A and EGFR/MMP-2 mRNA expression was observed in tumor samples. Underexpression of INPP5A was significantly correlated with overexpression of TWIST1, MMP-2, and EGFR in different invasiveness and aggressiveness pathological features of the ESCCs (P < 0.05). CONCLUSIONS The results propose a tumor suppressor role for INPP5A and oncogenic function for concomitant expression of the other genes in ESCC invasion and metastasis. The current study is the first report elucidating the correlation between the downregulation of INPP5A and upregulation of TWIST1, MMP-2, and EGFR in ESCC and introduces this panel of the genes as a marker for poor prognosis of the disease.

Abstract
Chemotherapy is the main therapy for gastric cancer (GC) both before and after surgery, but the emergence of multidrug resistance (MDR) often leads to disease progression and recurrence. P-glycoprotein, encoded by MDR1, is a well-known multidrug efflux transporter involved in drug resistance development. Pygo2 overexpression has been identified in several cancers. Previous studies have shown that abnormal expression of Pygo2 is related to tumorigenesis, chemoresistance, and tumor progression. In this study, to evaluate the underlying relationship between Pygo2 and MDR1 in GC, we constructed GC drug-resistant cell lines, SGC7901/cis-platinum (DDP), and collected tissue from GC patients' pre-and post-chemotherapy. We found that Pygo2 was overexpressed in GC, especially in GC drug-resistant cell lines and GC patients who underwent neoadjuvant DDP-based chemotherapy. Pygo2 overexpression may precede MDR1 and correlates with MDR1 in GC patients. Furthermore, knock-down of Pygo2 induced downregulation of MDR1 and restored SGC7901/DDP's sensitivity to DDP. Further mechanistic analysis demonstrated that Pygo2 could modulate MDR1 transcription by binding to the MDR1 promoter region and promoting MDR1 activation. The overall findings reveal that Pygo2 may be a promising biomarker for monitoring drug resistance in GC by regulating MDR1.

Abstract
Background Bladder cancer (BCa) is a frequent urothelial malignancy with a high ratio of morbidity and mortality. Various genetic and environmental factors are involved in BCa progression. Since, majority of BCa cases are diagnosed after macroscopic clinical symptoms, it is required to find efficient markers for the early detection. Receptor tyrosine-kinases (RTKs) and non-receptor tyrosine-kinases (nRTKs) have pivotal roles in various cellular processes such as growth, migration, differentiation, and metabolism through different signaling pathways. Tyrosine-kinase deregulations are observed during tumor progressions via mutations, amplification, and chromosomal abnormalities which introduces these factors as important candidates of anti-cancer therapies. Main body For the first time in present review we have summarized all of the reported tyrosine-kinases which have been significantly associated with the clinicopathological features of BCa patients. Conclusions This review highlights the importance of tyrosine-kinases as critical markers in early detection and therapeutic purposes among BCa patients and clarifies the molecular biology of tyrosine-kinases during BCa progression and metastasis.

Abstract
Colorectal cancer (CRC) is one of the most common gastrointestinal cancers worldwide. Detection of CRC at the early stages of disease can play an important role in decrease of associated mortality rates. The Wnt signaling pathway is crucial for the progression of different cellular and developmental processes and Wnt pathway deregulation has been well characterized in a variety of cancers, particularly in CRC. The aim of this study was to analyze protein expression of Pygopus2 (PYGO2), the main transcription factor of Wnt pathway, in CRC tissues and evaluate its probable correlation with clinicopathological features of the patients. The expression pattern of PYGO2 was evaluated by immunohistochemistry in tumor tissues and their margin normal which is the piece of normal, or unaffected tissue excised from the surrounding the visible tumors in 46 CRC patients. A defined scoring system was applied to analyze immunostaining results. The expression of PYGO2 protein was detected in all tumor tissues. Furthermore, this expression was significantly higher in CRC samples than in normal tissues. There was a significant association between PYGO2 protein expression in CRC and tumor cell metastasis to the lymph nodes. Considering the significant expression of PYGO2 protein in colorectal tumor cells and its correlation with lymph node metastasis, this protein may be used as a biomarker for metastatic CRC as well as a putative therapeutic target to inhibit aggressiveness and metastasis of CRC.

Abstract
Abstract Background Esophageal cancer is one of the leading causes of cancer related deaths among the Iranians. There is still a high ratio of mortality and low 5 years survival which are related to the late onset and diagnosis. Majority of patients refer for the treatment in advanced stages of tumor progression. Main body It is required to define an efficient local panel of diagnostic and prognostic markers for the Iranians. Indeed such efficient specific panel of markers will pave the way to decrease the mortality rate and increase the 5 years survival among the Iranian patients via the early diagnosis and targeted therapy. Conclusion in present review we have reported all of the molecular markers in different signaling pathways and cellular processes which have been assessed among the Iranian esophageal cancer patients until now.

Abstract
BACKGROUND Our previous studies demonstrate that the major histocompatibility complex (MHC) is associated with the progression of esophageal squamous cell carcinoma (ESCC). HLA-DQA1, which belongs to the MHC Class II family, may be a potential biomarker in ESCC progression. However, the association between HLA-DQA1 and ESCC in high-incidence area of northern China has not been well characterized. The purpose of this study is to investigate the relationship of HLA-DQA1 expression with the progression and prognosis of ESCC. METHODS We analyzed the expression profiles of HLA-DQA1 in esophageal cancer (EC) samples in the TCGA database and validated HLA-DQA1 expression by immunohistochemistry, western blotting, and quantitative reverse-transcription polymerase chain reaction in matched EC and normal tissues, respectively. The correlation between HLA-DQA1 expression and clinicopathologic characteristics of ESCC was further analyzed. RESULT Immunohistochemical analysis indicated that the expression level of HLA-DQA1 in ESCC tissues was significantly higher than the matched normal tissues (P < .001). HLA-DQA1 mRNA and protein expression were significantly higher in ESCC tissues compared to the matched normal tissues. Patients with family history negative or with tumor sizes >4 cm were associated with higher HLA-DQA1 expression levels. A prognostic significance of HLA-DQA1 was also found by the Log-rank method, in which high expression of HLA-DQA1 was correlated with a shorter overall survival time. The receiver operating characteristic (ROC) curve analysis yielded the area under the ROC curve value of 0.693. Univariate and multivariate analyses also suggest that high expression of HLA-DQA1 is a potential indicator for poor prognosis of ESCC. CONCLUSIONS Our results demonstrate that HLA-DQA1 plays an important role in ESCC progression and may be a biomarker for ESCC diagnosis and prognosis, as well as a potential target for the treatment of patients with ESCC.

Abstract
BACKGROUND Epidermal growth factor receptor family members such as ErbB1 and ErbB3 are involved in tumor progression and metastasis. Although, there are various reports about the prognostic value of EGFR members separately in gastric cancer, there is not any report about the probable correlation between ErbB1 and ErbB3 co-expression and gastric cancer prognosis. In present study, we assessed the correlation between ErbB1 and ErbB3 co-overexpression (in the level of mRNA and protein expression) and gastric cancer prognosis for the first time. METHODS ErbB1 and ErbB3 expressions were analyzed by immunohistochemistry and real-time PCR in 50 patients with gastric cancer. Parametric correlations were done between the ErbB1 and ErbB3 expression and clinicopathological features. Multivariate and logistic regression analyses were also done to assess the roles of ErbB1 and ErbB3 in tumor prognosis and survival. RESULTS There were significant correlations between ErbB1/ErbB3 co-overexpression and tumor size (p = 0.026), macroscopic features (p < 0.05), tumor differentiation (p < 0.05), stage of tumor (p < 0.05), and recurrence (p < 0.05). Moreover, ErbB1/ErbB3 co-overexpression may predict the survival status of patients (p < 0.05). CONCLUSION ErbB1 and ErbB3 co-overexpression is accompanied with the poor prognosis and can be used efficiently in targeted therapy of gastric cancer patients.

Abstract
Background Esophageal squamous cell carcinoma (ESCC) is the most common histological type of esophageal cancer, with a poor prognosis. Deregulation of WNT and NOTCH signaling pathways is important in ESCC progression, which can be due to either malfunction of their components or crosstalk with other pathways. Therefore, identification of new crosstalk between such pathways may be effective to introduce new strategies for targeted therapy of cancer. A correlation study was performed to assess the probable interaction between growth factor receptors and WNT/NOTCH pathways via the epidermal growth factor receptor (EGFR) and Musashi1 (MSI1), respectively. Methods Levels of MSI1/EGFR mRNA expression in tumor tissues from 48 ESCC patients were compared to their corresponding normal tissues using real-time polymerase chain reaction. Results There was a significant correlation between EGFR and MSI1 expression (p = 0.05). Moreover, there was a significant correlation between EGFR/MSI1 expression and grade of tumor differentiation (p = 0.02). Conclusion This study confirms a direct correlation between MSI1 and EGFR and may support the important role of MSI1 in activation of EGFR through NOTCH/WNT pathways in ESCC.

Abstract
Background It has been shown that the expression of potassium channel tetramerization domain containing 12 (KCTD12) as a regulator of GABAB receptor signaling is reversely associated with gastrointestinal stromal tumors. In present study we examined the probable role of KCTD12 in regulation of several signaling pathways and chromatin remodelers in esophageal squamous cell carcinoma (ESCC). Methods KCTD12 ectopic expression was done in KYSE30 cell line. Comparative quantitative real time PCR was used to assess the expression of stem cell factors and several factors belonging to the WNT/NOTCH and chromatin remodeling in transfected cells in comparison with non-transfected cells. Results We observed that the KCTD12 significantly down regulated expression of NANOG, SOX2, SALL4, KLF4, MAML1, PYGO2, BMI1, BRG1, MSI1, MEIS1, EGFR, DIDO1, ABCC4, ABCG2, and CRIPTO1 in transfected cells in comparison with non-transfected cells. Migration assay showed a significant decrease in cell movement in ectopic expressed cells in comparison with non-transfected cells (p = 0.02). Moreover, KCTD12 significantly decreased the 5FU resistance in transfected cells (p = 0.01). Conclusions KCTD12 may exert its inhibitory role in ESCC through the suppression of WNT /NOTCH, stem cell factors, and chromatin remodelers and can be introduced as an efficient therapeutic marker.

Abstract
Pygo2 as a Wnt signaling pathway component has been detected in multiple cancer types. In this study, we identified Pygo2 expression features by immunohistochemistry in 73 central nervous system tumor specimens, in comparison with 14 normal brain tissues and surrounding non-tumorous tissues of tumor. Our study indicated that 59% of the patient tumor specimens exhibited positive Pygo2-staining and increases intensity with the grade of malignancy, especially for WHO grade III and IV gliomas, was observed high level expression, compared with normal brain tissues. Five out of nine WHO grade III anaplastic astrocytomas and seven out of nine WHO grade IV glioblastomas showed Pygo2-positive staining. The analysis of Pygo2 gene expression by quantitative real-time PCR of additional ten fresh patient samples yielded similar results. Further studies performed with stable cell lines in vitro demonstrated that Pygo2 render cells higher proliferation rate, migration and anchorage-independent colony-forming ability in soft agar. Taken together, our studies suggest an important role of Pygo2 in brain tumor progression.

Abstract
Homeobox (HOX) transcription factors and NOTCH signaling pathway are critical regulators of stem cell functions, cell fate in development and homeostasis of gastrointestinal tissues. In the present study, we analyzed cross talk between NOTCH pathway and HOX genes through assessment of probable correlation betweenMAML1 and MEIS1 as the main transcription factor of NOTCH pathway and enhancer of HOX transcriptional machinery, respectively in esophageal squamous cell carcinoma (ESCC) patients. Fifty one ESCC cases were enrolled to assess the levels of Meis1 and Maml1 mRNA expression using real-time polymerase chain reaction (PCR). Only 3 out of 51 (5.9%) cases had MEIS1/MAML1 under expression and 2/51 (3.9%) cases had MEIS1/MAML1over expression. Nine out of 51 samples (17.6%) have shown MEIS1 under expression and MAML1 over expression. There was a significant correlation between MAML1and MEIS1mRNA expressions (p ≤ 0.05). There were significant correlations between MEIS1 under/MAML1 over expressed cases and tumor location (p = 0.05), tumor depth of invasion (p = 0.011), and sex (p = 0.04). Our results showed that MEIS1 may have a negative role in regulation of MAML1expression during the ESCC progression.

Abstract
Pygo2, a vital component of the Wnt signaling pathway that was recently discovered, has been reported to be closely related to the tumorigenesis of several types of malignant tumors. There are two highly conservative domains named NHD in the N terminus and PHD in the C terminus of Pygo2. Previous studies have shown that the Pygo2 PHD domain can act as a protein code reader to link the chromatin remodeling complex to specific changes in gene transcription, as demonstrated for the Wnt target genes. Furthermore, the activity of the chromatin remodeling is further facilitated by the recruiting of histone methyltransferase and acetyltransferase through the interaction with the Pygo2 NHD domain. However, the molecular mechanism of Pygo2 in the tumor development is still poorly understood. In the present study, we intend to review the structure and role of Pygo2 in tumor progression.

Abstract
PURPOSE Developmental pathways such as Wnt and Notch are involved in different cellular functions from the cell cycle regulation to self-renewal. Therefore, aberrations in these pathways may cause tumorigenesis. Msi1 has a critical regulatory role for the Wnt and Notch pathways. In the present study, we have assessed the probable correlation between the Msi1 and MAML1 in esophageal squamous cell carcinoma (ESCC) progression and metastasis. METHODS Levels of Msi1 and MAML1 mRNA expression in 51 ESCC patients were compared to the normal tissues using real-time polymerase chain reaction (PCR). RESULTS Nine out of 51 (17.6 %) cases had Msi1/MAML1 overexpression, and there was a significant correlation between such overexpressed cases and tumor location (p = 0.013). CONCLUSIONS We showed that there is not any direct correlation and feedback between the Msi1 and MAML1 in ESCC patients.

Abstract
There is an inevitable association between cell signaling pathways and tumorigenesis. Wnt and notch pathways play important roles during development and self-renewal. Beside the independent role of such pathways on tumor progression, different cross talks between these pathways through tumorigenesis are emphasized. In this study, we analyzed cross talk between Wnt and NOTCH signaling pathways through assessment of probable correlation between MAML1 and PYGO2 as the main transcription factors of these pathways, respectively in esophageal squamous cell carcinoma (ESCC) patients. Levels of MAML1 and PYGO2 mRNA expression in 48 ESCC patients were compared to the correlated margin normal tissues using real-time polymerase chain reaction (PCR). Eleven out of 48 patients (22.9 %) have shown the concomitant MAML1/PYGO2 over expression in significant correlation with tumor size (p = 0.046) and depth of tumor invasion (p = 0.050). We showed that there is a significant correlation and feedback between these markers during the ESCC progression and metastasis.

Abstract
Pygo2 has been discovered as an important Wnt signaling component contributing to the activation of Wnt-target gene transcription. In the present study, we discovered that Pygo2 mRNA and protein levels were up-regulated in the majority of (152/209) human brain glioma tissues and five glioma cell lines, and significantly correlated with the age, the WHO tumor classification and poor patient survival. The histone methyltransferase complex components (WDR5, Ash2, and menin, but not CXCC1 or NCOA6) were down-regulated at the promoter loci of Wnt target genes after Pygo2 knockdown, and this was accompanied by the down-regulation of Wnt/β-catenin pathway activity. Further, we demonstrated that the involvement of Pygo2 in the activation of the Wnt pathway in human glioma progression is through up-regulation of the H3K4me3 (but not H3K4me2) by promoting the recruitment of the histone methyltransferase MLL1/MLL2 complex to Wnt target gene promoters. Thus, our study provided evidence that Pygo2 functions as a novel prognostic marker and represents a potential therapeutic target.

[PMID: 26876203 DOI: 10.1038/onc.2016.10] [Citation(s) in RCA: 59] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2015] [Revised: 12/24/2015] [Accepted: 12/27/2015] [Indexed: 12/19/2022]
Abstract
The Wnt/β-catenin pathway has important roles in chemoresistance and multidrug resistance 1 (MDR1) expression in some cancers, but its involvement in breast cancer and the underlying molecular mechanism are undefined. In this study, we demonstrated that the Wnt/β-catenin pathway is activated in chemoresistant breast cancer cells. Using a Wnt pathway-specific PCR array screening assay, we detected that Pygo2, a newly identified Wnt/β-catenin pathway component, was the most upregulated gene in the resistant cells. Additional experiments indicated that Pygo2 activated MDR1 expression in the resistant cells via the Wnt/β-catenin pathway. Moreover, the inhibition of Pygo2 expression restored the chemotherapeutic drug sensitivity of the resistant cells and reduced the breast cancer stem cell population in these cells in response to chemotherapy. Importantly, these activities induced by Pygo2 were mediated by MDR1. We also determined the effect of Pygo2 on the sensitivity of breast tumors resistant to doxorubicin in a mouse model. Finally, RNA samples from 64 paired patient tumors (before and after chemotherapy) highly and significantly overexpressed Pygo2 and/or MDR1 after treatment, thus underlining a pivotal role for the Pygo2-mediated Wnt/β-catenin pathway in the clinical chemoresistance of breast cancer. Our data represent the first implication of the Wnt/β-catenin pathway in breast cancer chemoresistance and identify potential new targets to treat the recurrence of breast cancer.

Abstract
Deregulation of developmental signaling pathways such as Wnt/b-catenin and NOTCH are commonly observed in different cancers. A normal wnt pathway is essential for development and tissue homeostasis to preserve a normal balance between the differentiation and proliferation. PYGO2 is the main transcription factor of wnt pathway, while Msi1 is one of the wnt inhibitors. In this study we assessed the correlation between Msi1 and PYGO2 mRNA expression using Real time polymerase chain reaction in 48 esophageal squamous cell carcinoma (ESCC) patients. Although, there was not any significant correlation between the levels of Msi1 and PYGO2 mRNA expression, we observed a significant correlation between the Msi1 and PYGO2 overexpressed cases and depth of tumor invasion (p = 0.05). In conclusion, despite the role of these markers in tumor depth of invasion there is not any feedback between Msi1 and PYGO2 gene expression in ESCC.

Abstract
Cancer stem cells (CSCs) are a vital subpopulation of cells to target for the treatment of cancers. In oesophageal squamous cell carcinoma (ESCC), there are several markers such as CD44, ALDH, Pygo2, MAML1, Twist1, Musashi1, Side population (SP), CD271 and CD90 that have been proposed to identify the cancer stem cells in individual cancer masses. It has also been demonstrated that stem cell markers like ALDH1, HIWI, Oct3/4, ABCG2, SOX2, SALL4, BMI-1, NANOG, CD133 and podoplanin are associated with patient's prognosis, pathological stages, cancer recurrence and therapy resistance. Finding new cancer stem cell targets or designing drugs to manipulate the known molecular targets in CSCs could be useful for improvements in clinical outcomes of the disease. To conclude, data suggest that CSCs in oesophageal squamous cell carcinoma are related to resistance to therapy and poor prognosis of patients with ESCC. Therefore, innovative insights into CSC biology and CSC-targeted therapies will help to achieve more effective management of patients with oesophageal squamous cell carcinoma.

Abstract
Notch signaling is an important cellular pathway which affects the development and function of many organs. It plays critical roles in maintaining of progenitor stem cell population as well as balancing cell proliferation, survival, differentiation and apoptosis. It has been shown that notch signaling is aberrantly activated during the carcinogenesis of a variety of human cancers. In this study we aimed to explore activation of this signaling pathway in esophageal squamous cell carcinoma (ESCC) through expressional analysis of notch signaling target genes. The mRNA expression of HEY1 and HEY2 was comparatively analyzed by real-time PCR in tumor and related margin normal tissues of 50 ESCC patients. Comparative quantitative real-time PCR indicates the overexpression of HEY1 and HEY2 in 54 and 30% of ESCC samples, respectively. Overexpression of HEY1 was significantly associated with stage of the tumor (p = 0.048) and tumor location (p = 0.008). HEY2 overexpression was also significantly correlated to node metastasis of tumor cells (p = 0.043). Overexpression of HEY1 and HEY2 in ESCC is correlated to different indices of poor prognosis and it is extrapolated that such overexpression is important in progression and development of ESCC tumorigenesis. To the best of our knowledge, this is the first report introducing aberrant activation of notch signaling target genes in ESCC, where it plays roles in development and progression of the malignancy and may be considered in therapeutic modalities to restrict ESCC progression.

Abstract
INTRODUCTION Gastric cancer (GC) is one of the leading causes of cancer-related death in Iran. Genome stability is one of the main genetic issues in cancer biology which is governed via the different repair systems such as DNA mismatch repair (MMR). A clear correlation between MMR defects and tumor progression has been shown. Beside the genetic mutations, epigenetic changes also have a noticeable role in MMR defects. METHODS Here, we assessed promoter methylation status and the level of hMLH1mRNA expression as the main component of MMR system in 51 GC patients using the methylation-specific PCR and real-time PCR, respectively. Moreover, we performed a promoter methylation study of the E-cadherin gene promoter. RESULTS It was observed that, 12 out of 39 cases (23.5%) had hMLH1 overexpression. Hypermethylation of hMLH1 and E-cadherin promoter regions were observed in 25.5 and 36.4%, respectively. Although, there was no significant correlation between hMLH1 mRNA expression and clinicopathological features, there are significant correlations between E-cadherin promoter methylation and tumor stage (p = 0.028) and location (p = 0.025). The rate of hMLH1 promoter methylation in this study was lower than that in the other population, showing the importance of the other mechanisms, in gastric tumorigenesis. CONCLUSION The results of this study indicate that DNA repair system is adversely affected by hypermethylation of hMLH1 in a fraction of gastric cancer patients. Additionally, E-cadherin hypermethylation seen in a subset of our gastric cancer patients is consistent with other reports showing correlation with aggressiveness and metastasis of gastric cancer.

Abstract
Only 10 % of cancer-related deaths result from primary tumors; most are caused by metastatic tumors. It is believed that the metastatic power of tumor cells is attributed to features of a stem cell-like subpopulation of tumor cells known as cancer stem cells (CSCs). Cancer stem cells are resistant to chemotherapeutic treatments and can induce dormancy in tumor cells for long periods. Detection, isolation, and characterization of CSCs in solid tumors are hallmarks of cancer-targeted therapies in recent years. There are inevitable similarities between normal and cancer stem cells; therefore, finding specific methods or markers to differentiate them is critical to cancer therapies. Considering CSCs involvement in tumor relapse and chemotherapeutic resistance, identification of such cells in tumors is imperative for effective targeted therapy. The present review introduces practical and specific protocols used to isolate CSCs from solid tumors from colon, esophagus, liver, breast, brain, and cervix.

Abstract
Cancer stem cells, as a subgroup of tumor cells, resemble critical properties of embryonic stem cells (ESCs) such as self-renewal and maintenance of stemness state. SALL4 and SOX2 are two main transcription factors involving in maintenance of pluripotency, self-renewal and cell fate decision in ESCs. In this study, we aimed to elucidate the expression levels of these important transcription factors in esophageal squamous cell carcinoma (ESCC) and to reveal their probable roles in maintenance and progression of the disease. The expression level of SALL4 and SOX2 was analyzed in fresh tumoral tissues in comparison with distant tumor-free tissues of 50 ESCC patients by relative comparative real-time PCR. SALL4 and SOX2 were overexpressed in 64 and 32% of tumor samples, respectively, in significant correlation with each other (p = 0.028). There was a significantly inverse correlation between low level of SALL4 expression and metastasis of tumor cells into the lymph nodes (p = 0.035). Furthermore, co-overexpression of the genes was significantly correlated with the depth of tumor invasion (p = 0.045) and metastasis to the lymph nodes (p = 0.049). SALL4 and SOX2 are co-overexpressed in ESCC and have a significant correlation with invasion and metastasis of the disease. To the best of our knowledge, this is the first report of SALL4 clinical relevance in ESCC to date. The clinical consequences of SALL4-SOX2 association suggest a possible functional interaction between these factors in regulation of ESCC maintenance and aggressiveness and introduce these regulators of stemness state as potentially interesting therapeutic targets to bring new opportunities for onco-therapeutic modalities.

Abstract
BACKGROUND MicroRNAs are regulators that can play an essential role in tumorigenesis. Although miR-302 families have been suggested to be tumor repressors in human cancer, the mechanism by which they suppress tumor development remains to be defined. In this study, we discover that miR302b suppresses tumor proliferation may due to directly targeting EGFR in human hepatocellular carcinoma (HCC). METHODS QRT-PCR was used to assess miR-302b and EGFR expression in 27 pairs of clinical hepatocellular carcinoma tissues and their corresponding adjacent nontumorous liver tissues. MTT, colony formation, immunofluorescence staining, and cell cycle assays were used to examine the tumor suppressor role of miR302b in cell proliferation. Luciferase assays were performed to assess the EGFR was a novel target of miR-302b. Western blot assay was used to validate the protein expression level. RESULTS We demonstrated that miR-302b was frequently down-regulated, whereas EGFR was up-regulated in 27 pairs of clinical HCC and non-tumorous counterparts. The dual-luciferase reporter assays revealed that EGFR was a novel target of miR-302b. Re-expression of miR-302b resulted in the inhibition of proliferation in hepatocellular carcinoma SMMC-7721 cells. The silencing of EGFR by miR-302b or siEGFR led to down-regulation of proliferation-related proteins, such as AKT2, CCND1, and CDK2. CONCLUSION miR-302b suppresses HCC growth may due to targeting the EGFR/AKT2/CCND1 pathway.
