Abstract
Early diagnosis of esophageal squamous cell carcinoma (ESCC), a common malignant tumor with a low overall survival rate due to metastasis and recurrence, is critical for effective treatment and improved prognosis. Raman spectroscopy, an advanced detection technology for esophageal cancer, was developed to improve diagnosis sensitivity, specificity, and accuracy. This study proposed a novel, effective, and noninvasive Raman spectroscopy technique to differentiate and classify ESCC cell lines. Seven ESCC cell lines and tissues of an ESCC patient with staging of T3N1M0 and T3N2M0 at low and high differentiation levels were investigated through Raman spectroscopy. Raman spectral data analysis was performed with four machine learning algorithms, namely principal components analysis (PCA)- linear discriminant analysis (LDA), PCA-eXtreme gradient boosting (XGB), PCA- support vector machine (SVM), and PCA- (LDA, XGB, SVM)-stacked Gradient Boosting Machine (GBM). Four machine learning algorithms were able to classifiy ESCC cell subtypes from normal esophageal cells. The PCA-XGB model achieved an overall predictive accuracy of 85% for classifying ESCC and adjacent tissues. Moreover, an overall predictive accuracy of 90.3% was achieved in distinguishing low differentiation and high differentiation ESCC tissues with the same stage when PCA-LDA, XGM, and SVM models were combined. This study illustrated the Raman spectral traits of ESCC cell lines and esophageal tissues related to clinical pathological diagnosis. Future studies should investigate the role of Raman spectral features in ESCC pathogenesis.

Relationship Between PTEN and Angiogenesis of Esophageal Squamous Cell Carcinoma and the Underlying Mechanism. Front Oncol 2021; 11:739297. [PMID: 34796109 PMCID: PMC8593196 DOI: 10.3389/fonc.2021.739297] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Accepted: 10/19/2021] [Indexed: 11/13/2022] Open
Abstract
Esophageal squamous cell carcinoma (ESCC) has high morbidity and mortality rates owing to its ability to infiltrate and metastasize. Microvessels formed in early-stage ESCC promote metastasis. Phosphatase and tensin homolog (PTEN) mediates macrophage polarization, but its effect and mechanism on early ESCC angiogenesis are unclear. To explore the molecular mechanism underlying early ESCC metastasis through blood vessels, we investigated the relationship between PTEN/phosphoinositide 3-kinase (PI3K)/p-AKT protein levels, number of infiltrated macrophages, and angiogenesis in ESCC and ESCC-adjacent normal esophageal mucosa tissues from 49 patients. Additionally, PTEN was overexpressed or silenced in the esophageal cancer cell line EC9706, and its supernatant served as conditioning medium for M1 tumor-associated macrophages (TAMs). The culture medium of macrophages served as conditioning medium for esophageal tumor-associated vascular endothelial cells (TECs) to study the biological behavior of PTEN-plasmid, PTEN-siRNA, and control TECs. We found that M1 TAM infiltration in ESCC tissues was low, whereas M2 TAM infiltration was high. Microvessel density was large, PTEN was down-regulated, and the PI3K/AKT pathway was activated in ESCC specimens. These parameters significantly related to the depth of tumor invasion, lymph node metastasis, and pathological staging of ESCC. Silencing of PTEN in EC9706 cells significantly activated the PI3K/AKT signaling pathway in macrophages, promoting M1-to-M2 TAM polarization and enhancing TECs’ ability to proliferate, migrate, invade, form tubes, and secrete vascular endothelial growth factor. We believe that PTEN silencing in esophageal cancer cells activates the PI3K/AKT signaling pathway in macrophages via the tumor microenvironment, induces M2 TAM polarization, and enhances the malignant behavior of TECs, thereby promoting ESCC angiogenesis. Our findings lay an empirical foundation for the development of novel diagnostic and therapeutic strategies for ESCC.

Abstract
OBJECTIVES High-risk human papillomavirus (HR-HPV) is an important risk factor for esophageal cancer. Macrophages constitute a crucial immune medium for regulating HPV-related tumors; however, the specific regulatory mechanisms remain unknown. Therefore, the purpose of our current study was to investigate the mechanism by which HPV16E6 regulates macrophages to promote the invasion and metastasis of esophageal cancer. METHODS HPV16E6 infection was detected by polymerase chain reaction. Immunohistochemistry was used to verify the distribution of tumor-associated macrophages (TAMs) and MMP-9 expression in esophageal squamous cell carcinoma tissues (ESCCs), and cancer adjacent normal tissues (CANs) from Kazakh patients. ESCC cells were transfected with a plasmid over-expressing HPV16E6 and non-contact cocultured with macrophages. RESULTS The infection rate of HPV16E6 in Kazakh ESCCs was clearly higher than that in CANs (P < 0.05). The density of CD163-positive TAMs was significantly positively correlated with HPV16E6 infection in ESCCs (P < 0.05). After coculturing macrophages and EC9706 cells transfected with the HPV16E6 plasmid, the phenotype of macrophages transformed into M2 macrophages. The migration and invasion ability of ESCC cells were higher in the HPV16E6-transfected and coculture group than in the HPV16E6 empty vector-transfected and non-cocultured HPV16E6-transfected groups (all P < 0.05). The density of M2-like TAMs in ESCCs was positively correlated with the level of MMP-9 expression. MMP-9 expression in the HPV16E6-ESCC coculture macrophages group was substantially higher than that in controls (all P < 0.05). CONCLUSIONS HPV16 infection mediates tumor-associated macrophages to promote ESCC invasion and migration.

High expression of spermatogenesis associated serine rich 2 promotes tumorigenicity in esophageal squamous cell carcinoma cells and is associated with poor patient prognosis. Exp Ther Med 2021; 22:698.

Abstract
Spermatogenesis associated serine rich 2 (SPATS2), recognized as a cytoplasmic RNA-binding protein, is implicated in the tumorgenicity of several cancers. However, the potential role of SPATS2 in esophageal squamous cell carcinoma (ESCC) is yet to be elucidated. The present study aimed to explore the functional implication of SPATS2 in ESCC. The ESCC cell lines Eca109 and KYSE-150 were used to conduct loss-of-function experiments. The expression patterns of SPATS2 in patients with ESCC were obtained from Oncomine, The Cancer Genome Atlas and Genotype-Tissue Expression databases. Reverse transcription-quantitative PCR and western blot analysis were applied to determine the expression levels of SPATS2 in ESCC cells. The proliferation of ESCC cells was measured via cell proliferation and colony-formation assays. Subsequently, the migration and invasion capacities of ESCC cells were observed using Transwell assays. Finally, the expression levels of P53, cyclin E, matrix metalloproteinase (MMP)-9 and neuronal-cadherin were determined via western blot analysis. SPATS2 was expressed at higher levels in ESCC tissues compared with the controls, and high expression of SPATS2 was associated with poor prognosis. ESCC cell line proliferation, migration and invasion abilities were suppressed after silencing SPATS2. Moreover, following knockdown of SPATS2, the proteins cyclin E, MMP-9 and N-cadherin were expressed at markedly decreased levels, while P53 expression was increased. In summary, the results of the present study suggest that SPATS2 promotes ESCC development and progression, providing potential insights into future ESCC targeted treatment.

Abstract
Macrophages are a double-edged sword with potential cancer-promoting and anticancer effects. Controversy remains regarding the effect of macrophages, especially M1 macrophages, on tumor promotion and suppression. We aimed to investigate the role of M1 macrophages in the occurrence and progression of esophageal squamous cell carcinoma (ESCC). Analyzing the data in Gene Expression Omnibus database by the CIBERSORT algorithm found that M1 macrophages were one of the important components of many immune cells in ESCCs, and the increase in their number was obviously negatively correlated with tumor T staging. This result was verified by our experimental data: the density of CD68/HLA-DR double-stained M1 macrophages in ESCC tumor nest and tumor stroma was significantly higher than that in cancer-adjacent normal (CAN) tissues. The density of M1 macrophages in ESCC tumor nest was negatively correlated with the patient's lymph node metastasis and clinical stage (P < 0.05), and the negative tendency was more obvious for M1 macrophages in ESCC tumor stroma (P < 0.001). Exposure to M1 macrophage-conditioned medium inhibited ESCC cell migration and invasion ability significantly (P < 0.05). Moreover, the increased M1 macrophage density in ESCC tumor stroma correlated positively with good prognosis of ESCC. M1 macrophages were involved in inhibiting ESCC cell migration and invasion, which could serve as a good prognostic factor in patients with ESCC.

Abstract
Vascular endothelial growth factor (VEGF) and Matrix metalloproteinases (MMPs) are believed to participate in infiltration of tumors. High mortality of esophageal squamous cell carcinoma (ESCC) related to its primary infiltration; however, it is not clear whether the expression of VEGF and MMPs is involved in this process. Screening of The Cancer Genome Atlas (TCGA) database showed that among the VEGF family and MMP9, VEGF-A, VEGF-C, and MMP-9 mRNA were overexpression in ESCC. This result was verified using the Oncomine database and in Kazakh patients with ESCC. Overexpression of VEGF-C and MMP-9 and positive association with advanced esophageal cancer and invading ESCC cells (Gene Expression Omnibus (GEO): GSE21293). Immunohistochemical staining revealed that VEGF-C and MMP-9 were overexpressed in Kazakh ESCCs. VEGF-C expression was related to invasive depth, tumor-node-metastasis (TNM) staging, lymphatic, and lymph node metastasis of ESCC. The linear association between them was further confirmed in TCGA database and the specimens from Kazakh patients with ESCC. Patients with both proteins expression had tumors with greater aggressiveness, suffered from poor prognosis compared with patients who did not express either protein or expressed protein alone. Both proteins expression predicted high invasiveness of ESCC, which is related to worse prognosis of Kazakh ESCCs.

Abstract
AIMS Amplified in liver cancer 1 gene (ALC1), a recently identified oncogene, was reported to be overexpressed in esophageal cancer cell lines and identified as a target oncogene in esophageal cancer pathogenesis. However, little literature is available to illustrate its significance in cisplatin resistance of esophageal squamous cell carcinoma (ESCC) cells. The aim of the current study was to investigate the effect of ALC1 on cisplatin cytotoxicity of ESCC cells and to study the potential mechanisms. MAIN METHODS ALC1 at mRNA and protein levels were detected by qRT-PCR and western blot, respectively. Cell viability was evaluated using CCK-8 assay. Apoptosis was assessed using caspase-3/7 activity assay and flow cytometry analysis. Glycolysis level was evaluated by measuring glucose consumption and lactate production. The protein levels of p-protein kinase B (Akt) and Akt were determined by western blot. KEY FINDINGS ALC1 was highly expressed in ESCC cells compared with human normal esophageal epithelial Het-1A cells. ALC1 knockdown suppressed the viability, induced apoptosis and enhanced cisplatin cytotoxicity in ESCC cells. In addition, ALC1 knockdown inhibited glycolysis and inactivated the phosphatidylinositol 3-kinase (PI3K)/Akt pathway in ESCC cells. Mechanistically, activation of the PI3K/Akt pathway by 740Y-P blocked the effects of ALC1 knockdown on cisplatin cytotoxicity and glycolysis in ESCC cells. In contrast, inhibition of the PI3K/Akt pathway by LY294002 or glycolysis by 2-deoxyglucose resisted the effect of ALC1 overexpression on cisplatin cytotoxicity in ESCC cells. SIGNIFICANCE ALC1 knockdown enhanced cisplatin cytotoxicity of ESCC cells by inhibition of glycolysis through inactivation of the PI3K/Akt pathway.

Abstract
Previous studies have suggested that metformin, a biguanide family member widely used as an oral antidiabetic drug, may inhibit proliferation and induce apoptosis in certain types of cancer cell. However, the molecular mechanisms underlying metformin-associated anticancer effects, and in particular antimetastatic effects, remain to be fully understood. The present study assessed the efficacy of metformin in inhibiting the migration and invasion of the esophageal carcinoma cell line EC109, and evaluated the effect of metformin on the protein kinase B (AKT) signaling pathway. EC109 cells were treated with 0, 5, 10 or 20 mM metformin during the logarithmic growth phase. A Transwell assay and western blot analysis revealed that metformin inhibited the migration and invasion of EC109 cells, nuclear factor-κB activation, matrix metallopeptidase 9 and N-cadherin expression in a phosphorylated-AKT dependent manner. These results suggested that metformin inhibits the migration and invasion of human esophageal carcinoma cells by suppressing AKT phosphorylation and regulating the expression of migration- and invasion-associated genes.

Liu L, Yang Z, Ni W, Xuan Y. ADAMTS-6 is a predictor of poor prognosis in patients with esophageal squamous cell carcinoma. Exp Mol Pathol 2018; 104:134-139. [PMID: 29475036 DOI: 10.1016/j.yexmp.2018.02.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2017] [Revised: 01/14/2018] [Accepted: 02/20/2018] [Indexed: 11/19/2022]
Abstract
BACKGROUND A disintegrin and metalloprotease with thrombospondin motif (ADAMTS) enzymes play important roles in cell functions including adhesion, invasion, migration, and proliferation. ADAMTS-6 is a member of the ADAMTS family; reports of its relationship with esophageal squamous cell carcinoma (ESCC) progression are rare. It is unclear whether ADAMTS-6 could be an independent ESCC biomarker. METHODS ADAMTS-6 expression was detected by immunohistochemistry (IHC) in 171 paraffin-embedded ESCC specimens; relationships with patients' clinicopathological features and Twist-1 expression were analyzed by the Pearson Chi-square method, respectively. Overall survival (OS) and disease-free survival (DFS) were determined using the Kaplan-Meier method and compared using the long-rank test. RESULTS ADAMTS-6 was expressed mainly in the cytoplasm and nucleus; the expression was significantly higher in tumor tissues. Increased expression of ADAMTS-6 correlated with clinical stage (P = 0.009), pT stage (P = 0.042), lymph node metastasis (P = 0.014) and recurrence (P = 0.033). There were no significant correlations between ADAMTS-6 expression and other clinicopathological parameters including age, sex, tumor size, distant metastasis, differentiation, …chemotherapy, radiotherapy, CD68 expression and epithelial mesenchymal transition (EMT) status. Kaplan-Meier survival curves revealed that upregulated expression of ADAMTS-6 indicated short OS (P = 0.001) and DFS (P = 0.002). Multivariate analysis confirmed that high ADAMTS-6 expression was an independent factor for ESCC prognosis. ADAMTS-6 expression was significantly correlated with Twist-1 expression in ESCC cancer cells (P = 0.007) and stromal cells (P < 0.001). Patients with ESCC revealing expression of both ADAMTS-6 and Twist-1 exhibited significantly reduced OS and DFS rates than other patients. CONCLUSIONS High ADAMTS-6 expression is a useful marker of poor prognosis in patients with ESCC.

Mol Med Rep 2018; 17:5265-5271.

Abstract
Dysregulation of micro (mi)RNA-let-7 has been associated with the development and prognosis of multiple cancer types. Lin28, a RNA-binding protein, plays a conserved role in regulating the maturation of let-7 family proteins. However, few studies have focused on the effects of Lin28/let-7 on Wnt-activated esophageal squamous cell carcinoma (ESCC). Analysis of the expression of let-7a, let-7b and let-7c in clinical tissues revealed that lower let-7a expression was correlated with higher tumor node metastasis staging and recurrence in patients with ESCC. Furthermore, it was demonstrated that let-7a was inversely correlated with the migration and invasion of ESCC cells. In addition, epithelial-mesenchymal transition, and the expression of VEGF-C and MMP9 were effectively decreased by let-7a-mimic or siRNA-Lin28 pretreatment. Mechanistically, Lin28 functioned as the key factor in signal transduction, which regulated the expression of let-7a and the downstream genes along the Wnt signaling pathway. Taken together, these findings identified a biochemical and functional association between Lin28/let-7a, and the Wnt pathway in ESCC cells.

Abstract
M2 macrophages was domesticated by tumor microenvironment to produce some angiogenic molecules and protease, facilitating angiogenesis and matrix breakdown, promoting tumor invasive and metastasis. However, The function of M2 macrophages to progression of esophageal carcinoma, especially Kazakh esophageal carcinoma is still dimness. This study aims to investigate M2 macrophages correlated with matrix metalloproteinase-9 (MMP9) and microvessel density, and the role in the progression of Kazakh esophageal squamous cell carcinoma. CD163 and CD34 as the marker of M2 macrophages and endothelial cells, were used to identify the M2 macrophages density and microvessel density, respectively. Immunohistochemistry staining was evaluated the expression of MMP9. The number of infiltrated CD163-positive M2 macrophages in tumor islets and stroma was significantly higher than in cancer adjacent normal tissues. The increased of M2 macrophages and microvessel density were significantly correlated with more malignant phenotypes including lymph node metastasis and clinical stage progression. Meanwhile, the expression of MMP9 showed much higher level in esophageal squamous cell carcinoma than that in cancer adjacent normal tissues, and high expression of MMP9 in Kazakh esophageal squamous cell carcinoma was significantly associated with age, depth of tumor invasion, lymph node metastasis, and tumor clinical stage. The quantity of M2 macrophages in tumor stroma was positively associated with microvessel density and the expression of MMP9, and as an independent poorly prognostic factor for overall survival time of Kazakh esophageal squamous cell carcinoma. These findings suggest the increased number of M2 macrophages correlated with high expression of MMP9 and high microvessel density may contribute to the tumor aggressiveness and angiogenesis, promoting the progression of Kazakh esophageal squamous cell carcinoma.

[PMID: 28444744 DOI: 10.1111/bph.13836] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2016] [Revised: 03/22/2017] [Accepted: 04/17/2017] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND AND PURPOSE Aberrant activation of the cyclin D1-cyclin-dependent kinase 4/6 (CDK4/6)-Rb signalling pathway is common in oesophageal squamous cell carcinoma (ESCC). PD-0332991, a highly specific inhibitor of CDK4/6, has potent antitumour activity against many types of cancer. The purpose of this study was to examine the in vitro and in vivo antineoplastic effect of PD-0332991 against the growth and metastasis of ESCC cells. EXPERIMENTAL APPROACH Cell viability and any synergy between PD-0332991 and 5-fluorouracil or cisplatin were measured by MTS assay and CalcuSyn software respectively. Cell migration and invasion were detected by wound healing and transwell assays. Apoptosis was evaluated by flow cytometry after staining annexin V-FITC/PI. Cellular senescence was assessed by measuring SA-β-gal activity. Nude mouse xenograft models of ESCC were employed to determine the in vivo activity of PD-0332991 against tumour growth and lung metastasis. KEY RESULTS PD-0332991 inhibited cellular growth and induced mitochondrial-dependent apoptosis in ESCC cells. PD-0332991 also suppressed migration, invasion and the expression of MMP-2 in ESCC cells. Furthermore, PD-0332991 treatment caused cell senescence in a FOXM1-dependent manner. In addition, there was synergy between PD-0332991 and cisplatin or 5-fluorouracil. Importantly, the xenografted tumour experiments demonstrated that PD-0332991 potently inhibits ESCC cell growth and lung metastasis. CONCLUSIONS AND IMPLICATIONS PD-0332991 can elicit a strong antitumour activity against ESCC growth and metastasis and may be a promising candidate drug for the treatment of patients with ESCC. Our results warrant a clinical trial to further evaluate the efficacy of PD-0332991 in ESCC patients, even those with metastasis.

Abstract
Tumor associated macrophages (TAMs) play an important role in the growth, progression, and metastasis of tumors. The distribution of TAMs in Kazakh esophageal squamous cell carcinoma (ESCC) is not determined. We aimed to investigate the role of TAMs in the occurrence and progression of Kazakh ESCC. CD163 was used as the TAM marker, and immunohistochemistry (IHC) counts were used to quantify the density of TAMs in tumor nest and surrounding stroma. IHC staining was used to evaluate the expression of vascular endothelial growth factor C (VEGF-C) in Kazakh ESCC and cancer adjacent normal (CAN) tissues. The density of TAMs in Kazakh ESCCs tumor nest and stromal was significantly higher than that in CAN tissues. The increased number of CD163-positive TAMs in tumor nest and tumor stromal was positively associated with Kazakh ESCC lymph node metastasis and clinical stage progression. Meanwhile, the expression of VEGF-C in Kazakh ESCCs was significantly higher than that in CAN tissues. Overexpression of VEGF-C in Kazakh ESCCs was significantly associated with gender, depth of tumor invasion, lymph node metastasis and tumor clinical stage. The increased number of TAMs, either in the tumor nests or tumor stroma was positively correlated with the overexpression of VEGF-C, which may promote lymphangiogenesis and play an important role in the invasion and metastasis of Kazakh ESCC.

Abstract
Increasing evidence has demonstrated that histone deacetylase 2 (HDAC2) participates in the regulation of a variety of biological processes in numerous tumors. However, the potential role of HDAC2 in the development and progression of esophageal squamous cell carcinoma (ESCC) remains elusive. Immunohistochemistry was utilized to detect the expression of HDAC2, Cell Counting Kit-8 was used to determine the cell proliferation, and flow cytometry was employed to investigate cell cycle and cell apoptosis. Finally, western blotting was employed to detect the protein expression of cyclin D1, p21, B cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax). The present study found that expression of HDAC2 protein in ESCC tissues was significantly increased compared with atypical hyperplasia tissues and normal esophageal mucosa (P<0.001). The expression of HDAC2 was not associated with the age or gender of patients (P>0.05), but was closely associated with the histological grade, invasion depth, tumor-node-metastasis stage and lymph node metastasis, respectively (all P<0.001). HDAC2 small interfering RNA effectively downregulated the expression of HDAC2 protein in ESCC EC9706 cells. Downregulation of HDAC2 expression evidently inhibited cell proliferation, arrested cell cycle at the G0/G1 phase and induced cell apoptosis in ESCC EC9706 cells, coupled with increased expression of p21 and Bax proteins and decreased expression of cyclin D1 and Bcl-2 proteins. Overall, the present findings suggest that HDAC2 may play an important role in the development and progression of ESCC and be considered as a novel molecular target for the treatment of ESCC.

Abstract
OBJECTIVE More effective regimens for advanced esophageal squamous cell carcinoma (ESCC) are urgently needed. Therefore, a retrospective study concerning the efficacy and safety of nanoparticle albumin-bound paclitaxel plus cisplatin (nab-TP) versus solvent-based paclitaxel plus cisplatin (sb-TP) as a first-line therapy was conducted in Chinese patients with advanced ESCC. METHODS From June 2009 to June 2015, 32 patients were treated with nab-paclitaxel (125 mg/m2) on the first and eighth days (30 minutes infusion) and cisplatin (75 mg/m2) on the second day every 21 days (nab-TP arm). Also, 43 patients were treated with solvent-based paclitaxel (80 mg/m2) intravenously on the first and eighth days and the same dose of cisplatin (sb-TP arm). The two groups were compared in terms of objective response rate (ORR), disease control rate, progression-free survival (PFS), overall survival (OS), and safety profile. OS and PFS were estimated using Kaplan-Meier methods to determine associations between chemotherapy regimens and survival outcomes. RESULTS Nab-TP demonstrated a higher ORR (50% vs 30%; P=0.082) and disease control rate (81% vs 65%; P=0.124) than sb-TP. Median OS was similar for nab-TP and sb-TP (12.5 vs 10.7 months; P=0.269). However, nab-TP resulted in a longer median PFS (6.1 months [95% confidence interval: 5.3-6.9]) than sb-TP (5.0 months [95% confidence interval: 4.4-5.6]) (P=0.029). The most common adverse events included anemia, leukopenia, neutropenia, febrile neutropenia, and thrombocytopenia in both the groups and no statistically significant differences were observed between the groups. With statistically significant differences, significantly less grade ≥3 peripheral neuropathy, arthralgia, and myalgia occurred in the nab-TP arm (all P<0.05). Dose reduction, treatment delays, and second-line therapy were similar between the two regimens. There were no treatment-related deaths in either group. CONCLUSION Nab-paclitaxel plus cisplatin is found to be an effective and tolerable option for advanced ESCC in the People's Republic of China.

Reciprocal activation between STAT3 and miR-181b regulates the proliferation of esophageal cancer stem-like cells via the CYLD pathway. Mol Cancer 2016; 15:40. [PMID: 27189061 PMCID: PMC4869372 DOI: 10.1186/s12943-016-0521-7] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2016] [Accepted: 05/05/2016] [Indexed: 02/07/2023] Open
Abstract
Background Recent studies have suggested that cancer cells contain subpopulations that can initiate tumor growth, self-renew, and maintain tumor cell growth. However, for esophageal cancer cells, the relationship between STAT3, microRNAs and cancer stem cells remains unclear. Methods Serum-free culture was used to enrich esophageal cancer stem-like cells (ECSLC). Flow cytometry determined the proportion of ECSLC. qPCR were performed to examine expression level of stemness factors, mesenchymal markers, ATP-binding cassette (ABC) transporters, STAT3, miR-181b, CYLD. Western blot were performed to analyze the expression of STAT3, p-STAT3 and CYLD (cylindromatosis). BALB/c mice xenograft studies were conducted to evaluate the tumorigenicity of enriched ECSLC. Sphere formation assay and colony formation assays were employed to analyze the relationship between STAT3 and miR-181b. Luciferase assays were used to evaluate activity which CYLD is a target of miR-181b. Results Sphere formation cells (SFCs) with properties of ECSLC were enriched. Enriched SFCs in serum-free suspension culture exhibited cancer stem-like cell properties and increased single-positive CD44 + CD24-, stemness factor, mesenchymal marker expression ABC transporters and tumorigenicity in vivo compared with the parental cells. Additionally, we found that reciprocal activation between STAT3 and miR-181b regulated SFCs proliferation. Moreover, STAT3 directly activated miR-181b transcription in SFCs and miR-181b then potentiated p-STAT3 activity. Luciferase assays indicated that CYLD was a direct and functional target of miR-181b. Conclusion The mutual regulation between STAT3 and miR-181b in SFCs was required for proliferation and apoptosis resistance. STAT3 and miR-181b control each other’s expression in a positive feedback loop that regulates SFCs via CYLD pathway. These findings maybe is helpful for targeting ECSLC and providing approach for esophageal cancer treatments.

Fan T, Chen J, Zhang L, Gao P, Hui Y, Xu P, Zhang X, Liu H. Bit1 knockdown contributes to growth suppression as well as the decreases of migration and invasion abilities in esophageal squamous cell carcinoma via suppressing FAK-paxillin pathway. Mol Cancer 2016; 15:23. [PMID: 26956728 PMCID: PMC4782287 DOI: 10.1186/s12943-016-0507-5] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2015] [Accepted: 02/27/2016] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND There is growing evidence that Bit1 exerts different roles in the development and progression of human cancers. Although Bit1 was highly exhibited in ESCC tissues in our previous study, its roles and molecular mechanisms implicated in development and progression of ESCC remain unknown. METHODS Bit1 protein expression in ESCC cell lines and normal esophageal epithelial cell was detected by Western blotting. Bit1 protein expression mediated by Bit1 shRNA was investigated by Western blotting. MTT, migration assay, invasion experiment, ELISA and Flow cytometry were utilized to determine the effects of Bit1 knockdown on cell proliferation, migration, invasion and apoptosis, respectively. A xenograft model was used to examine in vivo tumourigenicity, and immunohistochemistry and TUNEL were utilized to evaluate the related protein expression and apoptosis. Gene microarray was determined by Agilent SurePrint G3 Human GE 8 × 60 K Microarray, the interaction of Bit1 and FAK proteins were detected by Immunoprecipitation and the key protein expressions of FAK-paxillin pathway were detected by Western blotting. RESULTS We found Bit1 expression in all human ESCC cell lines tested was significantly higher than that in normal esophageal epithelial cell Het-1A (P < 0.05), in which EC9706 presented the highest Bit1 level. Bit1 protein level was significantly downregulated at day 1 after transfection with specific shRNA against Bit1 (P < 0.05). At days 2 and 3, Bit1 level reached the lowest value after transfection with Bit1 shRNA. Moreover, Bit1 depletion contributed to growth inhibition in vitro and in vivo, reduced cell migration and invasion abilities, and induced cell apoptosis in EC9706 and TE1 cells. More importantly, Bit1 downregulation significantly lowered Bcl-2 and MMP-2 levels in EC9706 xenografted tumor tissues, meanwhile triggered apoptosis after treatment with different doses of Bit1 shRNA. Further gene microarray revealed that 23 genes in Bit1-RNAi group were markedly downregulated, whereas 16 genes were obviously upregulated. Notably, Bit1 intrinsically interacted with FAK protein in EC9706 cells. Moreover, paxillin was downregulated at mRNA and protein levels in Bit1 shRNA group, coupled with the decreases of FAK mRNA and protein expressions. CONCLUSION Bit1 may be an important regulator in cell growth, apoptosis, migration and invasion of ESCC via targeting FAK-paxillin pathway, and thereby combinative manipulation of Bit1 and FAK-paxillin pathway may be the novel and promising therapeutic targets for the patients with ESCC.

Abstract
Current clinical techniques in treating long-gap esophageal defects often lead to complications and high morbidity. Aiming at long-gap synthetic esophageal substitute, we had synthesized a biodegradable copolymer, poly(L-lactide-co-caprolactone) (PLLC), with low glass transition temperature. In this work, we developed a tubular PLLC porous scaffold using a self-designed tubular mold and thermal induced phase separation (TIPS) method. In order to enhance the interaction between tissue and scaffold, fibrin, a natural fibrous protein derived from blood fibrinogen, was coated on the scaffold circumferential surface. The fibrin density was measured to be 1.23 ± 0.04 mg/cm2. Primary epithelial cell culture demonstrated the improved in vitro biocompatibility. In animal study with partial scaffold implantation, in situ mucosa regeneration was observed along the degradation of the scaffold. These indicate that fibrin incorporated PLLC scaffold can greatly improve epithelial regeneration in esophagus repair, therefore serve as a good candidate for long-term evaluation of post-implantation at excision site.

Macrolide analog F806 suppresses esophageal squamous cell carcinoma (ESCC) by blocking β1 integrin activation. Oncotarget 2015; 6:15940-52. [PMID: 25909284 PMCID: PMC4599248 DOI: 10.18632/oncotarget.3612] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2015] [Accepted: 03/14/2015] [Indexed: 02/05/2023] Open
Abstract
The paucity of new drugs for the treatment of esophageal squamous cell carcinoma (ESCC) limits the treatment options. This study characterized the therapeutic efficacy and action mechanism of a novel natural macrolide compound F806 in human ESCC xenograft models and cell lines. F806 inhibited growth of ESCC, most importantly, it displayed fewer undesirable side effects on normal tissues in two human ESCC xenograft models. F806 inhibited proliferation of six ESCC cells lines, with the half maximal inhibitory concentration (IC50) ranging from 9.31 to 16.43 μM. Furthermore, F806 induced apoptosis of ESCC cells, contributing to its growth-inhibitory effect. Also, F806 inhibited cell adhesion resulting in anoikis. Mechanistic studies revealed that F806 inhibited the activation of β1 integrin in part by binding to a novel site Arg610 of β1 integrin, suppressed focal adhesion formation, decreased cell adhesion to extracellular matrix and eventually triggered apoptosis. We concluded that F806 would potentially be a well-tolerated anticancer drug by targeting β1 integrin, resulting in anoikis in ESCC cells.

Abstract
BACKGROUND Oesophageal adenocarcinoma (OAC) is one of the fastest rising malignancies with continued poor prognosis. Many studies have proposed novel biomarkers but, to date, no immunohistochemical markers of survival after oesophageal resection have entered clinical practice. Here, we systematically review and meta-analyse the published literature, to identify potential biomarkers. METHODS Relevant articles were identified via Ovid medline 1946-2013. For inclusion, studies had to conform to REporting recommendations for tumor MARKer (REMARK) prognostic study criteria. The primary end-point was a pooled hazard ratio (HR) and variance, summarising the effect of marker expression on prognosis. RESULTS A total of 3059 articles were identified. After exclusion of irrelevant titles and abstracts, 214 articles were reviewed in full. Nine molecules had been examined in more than one study (CD3, CD8, COX-2, EGFR, HER2, Ki67, LgR5, p53 and VEGF) and were meta-analysed. Markers with largest survival effects were COX-2 (HR=2.47, confidence interval (CI)=1.15-3.79), CD3 (HR=0.51, 95% CI=0.32-0.70), CD8 (HR=0.55, CI=0.31-0.80) and EGFR (HR=1.65, 95% CI=1.14-2.16). DISCUSSION Current methods have not delivered clinically useful molecular prognostic biomarkers in OAC. We have highlighted the paucity of good-quality robust studies in this field. A genome-to-protein approach would be better suited for the development and subsequent validation of biomarkers. Large collaborative projects with standardised methodology will be required to generate clinically useful biomarkers.

Abstract
Tumor metastasis is the main cause of cancer-related patient death. In this study, we performed a wound healing migration screen to search for a metastatic inhibitor within our library of natural compounds. We found that oblongifolin C (OC), a natural compound extracted from Garcinia yunnanensis Hu, is an effective inhibitor of metastasis in human esophageal squamous carcinoma Eca109 cells. The transwell migration and matrigel invasion assay results also showed that OC inhibits the migration of Eca109 cells and HepG2 cells. OC can increase the expression of tubulin, indicating that OC inhibits metastasis via tubulin aggregation. In addition, the Western blotting, real-time PCR, and immunostaining results indicated that OC increases the expression of keratin18. Furthermore, the knockdown of keratin 18 by small interfering RNAs inhibited the expression of tubulin and increased the metastasis of cancer cells, suggesting that keratin 18 is the upstream signal of tubulin and plays a vital role in metastasis. A subsequent study in a tail vein injection metastasis model showed that OC can significantly inhibit pulmonary metastasis, as revealed by immunohistochemistry staining. Taken together, our results suggest that OC inhibits metastasis through the induction of the expression of keratin 18 and may be useful in cancer therapy.

Abstract
Scaffolds mimicking hierarchical features of native extracellular matrices may facilitate cell growth and anatomical tissue regeneration. In our previous study, esophageal basement membrane (BM) was shown to be composed of interwoven fibers with mean diameter of 66 ± 24 nm (range 28-165 nm) and with abundant pores of unequal sizes. The main extracellular matrix (ECM) contents found in porcine esophageal BM were collagen IV, laminin, entactin, and proteoglycans. In this work, biodegradable polycaprolactone (PCL) and silk fibroin (SF) were spun with electrospinning technology, both individually and in combination, to fabricate fibrous scaffolds with diameters between 64 and 200 nm. The surface morphologies of PCL, PCL/SF, and SF scaffolds were observed under scanning electron microscopy. Their mechanical properties were tested and the cytocompatibility was evaluated in vitro via culture of primary epithelial cells (ECs). The SF or PCL/SF scaffold favorably promoted epithelial cell attachment and proliferation comparing with PCL scaffold. However, mitochondrial activity of epithelial cells was greatly promoted when major BM proteins were coated onto the electrospun scaffold to provide an ECM-like structure. Results from in vivo tests revealed that the electrospun scaffolds coated with BM protein possess good biocompatibility and capability to promote epithelium regeneration.

Abstract
AIM To investigate the expression of CD44v6 in stage T2-3N0M0 esophageal squamous cell carcinoma (ESCC) and its prognostic significance. METHODS The expression of CD44v6 in a series of 227 ESCC specimens was evaluated by immunohistochemistry (IHC). A reproducible semiquantitative method which took both staining percentage and intensity into account was applied for IHC scoring, and receiver operating characteristic (ROC) curve analysis was utilized to select the cut-off score for high or low IHC reactivity. Then, the correlations of CD44v6 expression with clinicopathological features of patients and its prognostic relevance were determined. RESULTS In the present study, the proportion of low CD44v6 expression was found significantly lower in Grade 3 of ESCC, than that of Grade 1 and Grade 2 of ESCC. There are no significant correlations between CD44v6 expression and other clinicopathological parameters including gender, age, tumor size, tumor location, depth of invasion and pathological stage. The Kaplan-Meier survival curves showed that up-regulated expression of CD44v6 indicated a poorer post-operative survival for ESCC patients of stage T2-3N0M0 (P=0.009), especially for those with T2 lesions (P=0.044) or with stage IIB diseases (P=0.005). Multivariate analysis also confirmed that CD44v6 expression [relative risk, 1.639; 95% confidence interval (CI): 1.142-2.354, P=0.007] and depth of invasion (relative risk, 1.487; 95% CI: 1.063-2.080, P=0.020) were independent prognostic factors. CONCLUSIONS Elevated CD44v6 expression may be an adverse prognostic indicator for patients with stage T2-3N0M0 ESCC, especially for those with T2 lesions or stage IIB diseases.

Abstract
Regulatory regions within the 3' untranslated region (UTR) influence polyadenylation (polyA), translation efficiency, localization and stability of mRNA. Alternative polyA (APA) has been considered to have a key role in gene regulation since 2008. Esophageal carcinoma is the eighth most common type of cancer worldwide. The association between polyA and disease highlights the requirement for comprehensive characterization of genome-wide polyA profiles. In the present study, global polyA profiles were established using the sequencing APA sites (SAPAS) method in order to elucidate the interrelation between 3' UTR length and the development of esophageal cancer. PolyA profiles were analyzed in squamous cell carcinoma, with ~903 genes identified to have shortened 3' UTRs and 917 genes identified to use distal polyA sites. The genes with shortened 3' UTRs were primarily associated with adherens junctions and the cell cycle. Four differentially expressed genes were also found, among which three genes were observed to be upregulated in cancerous tissue and involved in the positive regulation of cell motion, migration and locomotion. One gene was found to be downregulated in cancerous tissue, and associated with oxidative phosphorylation. These findings suggest that esophagitis may have a key role in the development of esophageal carcinoma. Furthermore, the genes with tandem 3' UTRs and differential expression identified in the present study may have the potential to be used as biomarkers for the diagnosis and prognosis of esophageal cancer.

Implications of Bit1 and AIF overexpressions in esophageal squamous cell carcinoma. Tumour Biol 2013; 35:519-27.

Abstract
Overwhelming evidence has demonstrated that Bit1 and AIF as mitochondrial proteins are implicated in the development and progression of a variety of tumors. However, their expressions and biological functions in esophageal squamous cell carcinoma (ESCC) remain to be delineated. In the present study, we found that Bit1, AIF, and Bcl-2 levels in ESCC tissues were significantly higher than those in normal esophageal epithelial tissues and dysplasia tissues (P < 0.05). Stepwise investigation demonstrated that Bit1 and Bcl-2 levels were both tightly associated with lymphatic metastasis and TNM staging (P < 0.05), and the levels of Bit1 mRNA as well as AIF and Bcl-2 proteins were both closely related to tumor differentiation (P < 0.05), but not related to the patients' age and gender (P > 0.05). Importantly, Bit1 mRNA and protein levels in ESCC with lymphatic metastasis and TNM staging in III and IV were markedly higher than that without lymphatic metastasis and TMN staging in I and II. Further analysis showed that expression of Bit1 protein was both positively correlated with expressions of AIF and Bcl-2 proteins (r = 0.408 and 0.405, respectively; P < 0.05). Correctively, our data cited earlier suggest that Bit1 plays pivotal roles in the development and progression of ESCC, and its biological functions in ESCC may be closely associated with AIF and Bcl-2 levels.

Abstract
OBJECTIVE This study was performed to evaluated the efficacy and safety of continuous infusional paclitaxel and 5-Fu as first-line chemotherapy in patients with advanced esophageal squamous cell cancer (ESCC). METHODS A total of 22 patients with advanced esophageal squamous cell cancer with no indications for surgery and radiation therapy, or recurrent patients were enrolled from October 2008 to November 2010. All were treated with PTX 20 mg/m2 was administered through a 16 hours continuous intravenous infusion on days 1 to 3, 8 and 9. DDP 3.75 mg/m2 was given on days 1 to 4 and 8 to 11, continuous infusional 5-FU over 24-hours on days 1 to 5 and 8 to 12 at a dose of 375 mg/m2, and folacin 60 mg orally synchronized with 5-Fu. The treatment was repeated every 21 days for at least two cycles. RESULTS 22 cases of all enrolled patients could be evaluated for the effect of treatment: 2 cases were CR, 9 cases PR, 5 cases SD and 2 cases PD, giving an overall response rate of 68.2% (15/22). The median time to progression was 7.0 months. The adverse reactions related to chemotherapy were tolerable; the most common toxic effects were marrow depression, alopecia, and fatigue. CONCLUSION Low-dose continuous infusional PTX over 16-hours and 5-fu over 24-hours is a promising regimen with good tolerability in treating patients with advanced esophageal squamous cell cancer.

Abstract
Swainsonine, a natural indolizidine alkaloid, has been reported to have antitumour effects, and can induce apoptosis in human gastric and lung cancer cells. In the present study, we evaluated the antitumour effects of swainsonine on several oesophageal squamous cell carcinoma cells and investigated relative molecular mechanisms. Swainsonine treatment inhibited the growth of Eca-109, TE-1 and TE-10 cells in a concentration-dependent manner as measured by MTT assay. Morphological observation, DNA laddering detection and flow cytometry analysis demonstrated that swainsonine treatment induced Eca-109 cell apoptosis in vitro. Further results showed that swainsonine treatment up-regulated Bax, downregulated Bcl-2 expression, triggered Bax translocation to mitochondria, destructed mitochondria integrity and activated mitochondria-mediated apoptotic pathway, followed by the release of cytochrome c, which in turn activated caspase-9 and caspase-3, promoted the cleavage of PARP, resulting in Eca-109 cell apoptosis. Moreover, swainsonine treatment inhibited Bcl-2 expression, promoted Bax translocation, cytochrome c release and caspase-3 activation in xenograft tumour cells, resulting in a significant decrease of tumour volume and tumour weight in the swainsoninetreated xenograft mice groups compared with that in the control group. Taken together, this study demonstrated that swainsonine inhibited Eca-109 cells growth through activation of mitochondria-mediated caspase-dependent pathway.

Abstract
Substantial evidence has demonstrated that platelet-derived growth factor-D (PDGF-D) is tightly associated with the development and progression of tumors. However, its biological functions in esophageal squamous cell carcinoma (ESCC) remain to be delineated. In this study, we found that expressions of PDGF-D mRNA and protein in ESCC tissues and cells were significantly higher than that in normal esophageal epithelial tissues (P < 0.05), further investigation showed that PDGF-D protein level in EC1 cells was obviously higher than those in EC9706 and Eca109 cells (P < 0.05). Elevated PDGF-D level was closely associated with TNM staging, tumor differentiation and lymph node metastasis (P < 0.05), but not related to the patients' age and gender (P > 0.05). In addition, down-regulation of PDGF-D expression markedly inhibited proliferation, reduced invasion and induced apoptosis in EC1 cells. More importantly, reduced PDGF-D level evoked the down-regulation of p65 and p-IκBα proteins and elevation of IκBα protein of NF-κB pathway, accompanied with the decreases of bcl-2 and MMP-9 protein expressions and increases of bax protein level and caspase-3 activities. Correctively, our data suggest that PDGF-D plays pivotal roles in the development and progression of ESCC, and combinations with PDGF-D and NF-κB pathway may be effective and feasible molecular targets for therapy of ESCC.

Abstract
Drugs that interfere with microtubule function can prevent cells from mitosis and may cause cell cycle arrest or apoptosis. Various microtubule targeting agents, both stabilizers and inhibitors, are used in a clinical setting to treat cancer. In the current study, we investigated the sensitivity of oesophageal cancer cells to different microtubule targeting agents. The current study demonstrated that different microtubule targeting agents disrupted the microtubule network and inhibited survival of oesophageal cancer cells in a dose-dependent manner. Interestingly, an additional cellular effect with inhibition of tyrosine phosphorylation of the EGFR and subsequent downregulation of EGFR-induced signalling was also observed, suggesting an additional mechanism of action for microtubule destabilising agents. A tyrosine phosphatase inhibitor, sodium orthovanadate, could reverse the EGFR dephosphorylation effects induced by microtubule targeting agents. The EGFR dephosphorylation could be reversed by a tyrosine phosphatase inhibitor, indicating that disruption of the microtubule network may lead to activation of a protein tyrosine phosphatase (PTP) that can regulate EGFR phosphorylation and activation, an effect of potential clinical relevance for combination therapies in patients.

Abstract
Cancer stem cells (CSCs) form spheres in vitro in serum-free suspension culture. Sphere formation is particularly useful to enrich the potential CSC subpopulations as a functional approach. Few reports are currently available on tumorspheres in esophageal cancer (EC). The present study focused on evaluating the cancer stem-like properties and analyzing the difference between spheroid and adherent cells of the Eca109 human EC cell line. Immunofluorescence and immunoblotting analysis revealed that EC tumorspheres expressed the stem cell markers Nanog and Oct4 more highly, but showed a decreased expression of the differentiation marker CK5/6. The spheroids were chemoresistant to cisplatin compared to the adherent cells (32.5 vs. 135.8 µM in IC50). Side population cells increased in tumorspheres compared to adherent cells (0.7 vs. 5.6%). A marked upregulation of drug-resistant genes (ABCG2 and MDR1) was observed in sphere-forming cells. We compared the profiles of adherent and spheroid cells by microarrays and obtained one representative differentially expressed gene, aldehyde dehydrogenase (ALDH). We also verified that the cancer stem-like cells of EC contained a high ALDH enzymatic activity. ALDH-positive cells were enriched by 11- to 12-fold in spheroids, compared to adherent cells (2.5 vs. 28.6%). Immunofluorescence and immunoblotting analysis also revealed a higher expression of ALDH in EC tumorspheres. In conclusion, our study verified that sphere-forming culturing can be utilized to demonstrate the putative esophageal CSCs, and identified a potential esophageal CSC surface marker, ALDH.

Abstract
The human cervical cancer oncogene 1 (HCCR-1), a novel human oncoprotein, has been shown to be upregulated in various human tumors and plays a critical role in tumorigenesis and tumor progression. Here, the authors investigated HCCR-1 level in esophageal squamous cell carcinoma (ESCC) tissues and assessed the correlation between HCCR-1 level and prognosis of the patients with ESCC. HCCR-1 levels were investigated by immunohistochemistry, in situ hybridization, real-time quantitative RT-PCR and Western blotting methods; Kaplan-Meier curve was used to evaluate the prognostic value of HCCR-1 level in patients with ESCC using log-rank test. HCCR-1 displayed high levels in ESCC tissues compared to squamous dysplasia tissues and normal esophageal epithelial tissues. No significant correlation was observed between the levels of HCCR-1 mRNA and protein and gender and age (all p>0.05) but obviously related to histological grade, clinical stage, and lymph node metastasis (all p<0.001). Moreover, the survival rate of the patients with low HCCR-1 levels was higher than that of the patients with high HCCR-1 levels (both p<0.05). These data demonstrate that HCCR-1 may be used as a novel predictor for the prognosis of the patients with ESCC.

Abstract
Emerging evidence indicates that RhoE as novel member of the Rho GTPases family plays an essential role in carcinogenesis and tumor progression of human various tumors, but the functional significance of RhoE in human esophageal squamous cell carcinoma (ESCC) is still unclear. In the current study, RhoE expression in ESCC tissues and cells was examined, and the biological functions of RhoE in ESCC cells were determined. The results revealed that RhoE expression at mRNA and protein levels was significantly downregulated in ESCC tissues and cell lines (P < 0.05). RhoE expression was tightly associated with differentiation degree, clinical staging, and lymph node metastasis of the patients with ESCC (P < 0.05), but no significant correlations were found between RhoE expression and gender or age of the patients with ESCC (P > 0.05). Additionally, we found that downregulation of RhoE expression in ESCC cells promoted cell proliferation, cell cycle progression, as well as cell invasion in vitro, and inhibited cell apoptosis. Conversely, upregulation of RhoE expression in ESCC cells inhibited cell proliferation, arrested cell cycle at G0/G1 phase, reduced cell invasion, and promoted cell apoptosis. Furthermore, the downregulation of RhoE expression significantly reduced PTEN level and enhanced pAkt level; however, elevation of RhoE expression markedly increased PTEN level and decreased pAkt level. Stepwise investigations demonstrated that overexpression of RhoE in ESCC cells increased the expressions of p27 and bax proteins but decreased the expressions of cyclin D1 and bcl-2 proteins. These data demonstrate that RhoE may play a driving role in the development and progression of ESCC, and targeting the RhoE may be an effective and feasible approach for treatment of ESCC.

Abstract
AIM To investigate whether down-regulation of peroxiredoxin 1 (Prx1) and/or peroxiredoxin 5 (Prx5) sensitizes human esophageal cancer cells to ionizing radiation (IR). METHODS Human esophageal carcinoma cell lines Eca-109 and TE-1 were used. Prx mRNA expression profiles in Eca-109 and TE-1 cells were determined using RT-PCR. Two highly expressed isoforms of Prxs, Prx1 and Prx5, were silenced by RNA interference (RNAi). Following IR, intracellular reactive oxygen species (ROS) and apoptosis were measured using flow cytometry, the activities of catalase, superoxide dismutase and glutathione peroxidase were measured, and the radiosensitizing effect of RNAi was observed. Tumor xenograft model was also used to examine the radiosensitizing effect of RNAi in vivo. RESULTS Down-regulation of Prx1 and/or Prx5 by RNAi does not alter the activities of catalase, superoxide dismutase and glutathione peroxidase, but made human tumor cells more sensitive to IR-induced apoptosis both in vitro and in vivo. When the two isoforms were decreased simultaneously, intracellular ROS and apoptosis significantly increased after IR. CONCLUSION Silencing Prx1 and/or Prx5 by RNAi sensitizes human Eca-109 and TE-1 cells to IR, and the intracellular ROS accumulation may contribute to the radiosensitizing effect of the RNAi.

Abstract
High cyclooxygenase 2 (COX-2) expression has been reported to be clinically associated with reduced cisplatin-based therapy efficacy in esophageal cancer. However, the benefit of including COX-2-selective inhibitors in therapeutic regimens remains uncertain. Thus, we sought to determine the effects of COX inhibitors on the cytotoxicity of cisplatin and to further explore the mechanism involved in human esophageal squamous cell carcinoma cells. Among the four tested COX inhibitors [celecoxib, 4-[5-(4-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl]benzenesulfonamide (SC-236), nimesulide, and indomethacin], all of which substantially suppressed prostaglandin E(2) production to a similar extent; only the COX-2-selective inhibitors celecoxib and SC-236 antagonized cisplatin-induced cytotoxicity and apoptosis in both cisplatin-resistant cells and their wild-type counterparts. Knockdown of COX-2 by small interference RNA failed to mimic the antagonizing effects of celecoxib and SC-236, implying that their action is COX-2-independent. Further mechanistic analysis revealed that the antagonizing effect of celecoxib and SC-236 on cytotoxic action of cisplatin was associated with decreased whole-cell cisplatin accumulation and DNA platination. Reduced influx, accompanied by the reduction of protein level of copper transporter 1, accounts for decreased intracellular cisplatin accumulation. In addition, combined treatment did not elicit greater antitumor activity than cisplatin or celecoxib monotherapy in vivo in an esophageal cancer xenograft model. Collectively, these data demonstrate that celecoxib antagonizes the cytotoxicity of cisplatin by decreasing intracellular cisplatin and DNA platination. The combination treatment also shows no beneficial effect compared with cisplatin or celecoxib monotherapy in vivo. Therefore, current clinical trials with celecoxib in combination with cisplatin should be approached with caution.

Abstract
Despite improvements in both surgical techniques and radio- and chemo-therapy regimens, the prognosis of esophageal cancer is poor. In pursuit of novel effective strategy, this study examined the effect of the BH3-mimetic GX15-070 on esophageal carcinoma cells. We discovered that GX15-070 inhibited the growth of esophageal cancer cells. There was synergism between GX15-070 and carboplatin or 5-fluorouracil. GX15-070 induced autophagy in esophagus cancer cell line EC9706 and osteosarcoma cancer cell line U2OS. 3-methyladenine and chloroquine, inhibitors of autophagy with distinct mechanisms, potentiated the cytotoxicity of GX15-070. In conclusion, GX15-070 inhibits growth of esophageal cancer cells.

Abstract
BACKGROUND Over a 10-year period from 1990, 445 patients with carcinoma of the oesophagus were admitted to the Norwegian Radium Hospital and 184 of these patients received treatment with curative intent. Even though surgery is the treatment of choice for these patients, many of them suffer from medical conditions that increase the risk for postoperative mortality and morbidity. In a retrospective study, the effect of the curative treatment offered to patients was explored with a particular focus on patients unfit for surgery. METHODS Medical data of the 184 patients treated with curative intent were reviewed and additional clinical information was retrieved from local hospitals and general practitioners. Preoperative radiotherapy followed by surgery was the standard curative treatment for operable patients. Medically inoperable patients were offered radical split-course hyperfractionated radiotherapy followed by a brachytherapy boost. RESULTS More than 50% (103/184) received non-surgical treatment only. Patients who received radical surgery (n = 81) were younger, had better performance status, less weight loss and dysphagia compared to patients treated with radical radiotherapy (n = 102). One patient received only photodynamic therapy. The 3-year survival was 29% for patients treated with radical surgery, and 8% for patients who received radical radiotherapy. The overall median crude survival for the two groups of patients were 20 months and seven months respectively. CONCLUSION The hyperfractionated radiotherapy provided symptom relief without extensive toxicity and with a possibility for cure for patients with oesophageal cancer who are unfit for surgery and chemoradiotherapy. The literature supports the curative potential of high dose accelerated hyperfractionated radiotherapy even though the optimal radiotherapy regimen still needs to be explored.

Abstract
Detection of esophageal disease in current clinical practice is limited to visualization of macroscopic epithelial morphology. In this work, we investigate high resolution autofluorescence imaging under ultra violet excitation to visualize microscopic epithelial changes related to disease progression using a bench top prototype microscope. The approach is based on the hypothesis that UV excitation light can only penetrate the superficial layer of cells resulting in autofluorescence images of the epithelial layer without using an additional image sectioning approach. The experiments were performed using ex vivo human esophagus biopsy specimens. The results indicate that cellular morphology information related to disease progression is attainable without tissue preparation.
