[PMID: 37563971 PMCID: PMC10523983 DOI: 10.1002/cam4.6431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 07/24/2023] [Accepted: 07/31/2023] [Indexed: 08/12/2023] Open
Abstract
BACKGROUND Ubiquitin-conjugating enzyme E2S (UBE2S), an E2 enzyme, is associated with the development of various tumors and exerts oncogenic activities. UBE2S is overexpressed in tumors, including hepatocellular carcinoma (HCC). However, the key molecular mechanisms of UBE2S in HCC still need additional research. The aim of this study was to explore the role of UBE2S in HCC. METHODS The expression levels of UBE2S in HCC tissues and cells were detected by western blot analysis, quantitative real-time polymerase chain reaction analysis (qRT-PCR), and immunohistochemistry (IHC). A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, wound healing assay, colony formation assay transwell assay, and animal models were used to detect the proliferation and migration ability of HCC cells. Western blot analysis, qRT-PCR, immunofluorescence, small-interfering RNA (siRNA), and plasmid transfection and coimmunoprecipitation (Co-IP) assays were performed to detect the interaction among UBE2S, von Hippel-Lindau (VHL), hypoxia-inducible factor 1-alpha (HIF-1α), Janus kinase-2 (JAK2), and signal transducer and activator of transcription 3 (STAT3). RESULTS In this study, we found that high UBE2S expression was associated with poor prognosis in HCC patients. In addition, UBE2S expression was upregulated in HCC tissues and cell lines. Knockdown of UBE2S inhibited the proliferation and migration of HCC cells in vitro and in vivo by directly interacting with VHL to downregulate the HIF-1α and JAK2/STAT3 signaling pathways. Accordingly, overexpression of UBE2S significantly enhanced the proliferation and migration of HCC cells in vitro via VHL to upregulate HIF-1α and JAK2/STAT3 signaling pathways. Furthermore, we found that downregulation of UBE2S expression enhanced the sensitivity of HCC cells to sorafenib in vivo and in vitro. CONCLUSION UBE2S enhances malignant properties via the VHL/HIF-1α and VHL/JAK2/STAT3 signaling pathways and reduces sensitivity to sorafenib in HCC. The findings of this study may open a new approach for HCC diagnosis and provide a potential option for the treatment of HCC.

[PMID: 34582005 DOI: 10.1007/s13402-021-00639-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 09/17/2021] [Indexed: 10/20/2022] Open
Abstract
PURPOSE Nuclear factor (NF)-κB signaling in cancer cells has been reported to be involved in tumorigenesis. Phosphorylation and degradation of inhibitor of NF-κBα (IκBα) is a canonical pathway of NF-κB signaling. Here, we aimed to identify and characterize noncanonical activation of NF-κB signaling by ubiquitin-conjugating enzyme E2S (UBE2S) in lung adenocarcinoma cells. METHODS TCGA and the Human Atlas Protein Database were used to analyze the survival rate of lung adenocarcinoma patients in conjunction with UBE2S expression. In addition, PC9, H460, H441 and A549 lung adenocarcinoma cells were used in this study. PC9 and H460 cells were selected for further analysis because they expressed different UBE2S protein levels. Specific IKK inhibitors, PS1145 and SC514, were used to assess IκBα phosphorylation. Western blot analysis was used to assess protein levels in PC9 and H460 cells. A scratch wound-healing assay was used to analyze the migrative abilities of PC9 and H460 cells. Overexpression and knockdown of UBE2S in H460 and PC9 cells were used to analyze their effects on downstream protein levels. Immunoprecipitation, immunofluorescent staining, glutathione S transferase (GST) pull-down and in vitro binding assays were used to analyze the interaction between UBE2S and IκBα. A luciferase assay was used to analyze activation of NF-κB signaling regulated by UBE2S. An in vivo zebrafish xenograft model was used to assess metastasis of PC9 cells regulated by UBE2S. RESULTS We found that UBE2S expression in lung adenocarcinoma patients was negatively related to survival rate. The protein level of UBE2S was higher in PC9 cells than in H460 cells, which was opposite to that observed for IκBα. PC9 cells showed a higher UBE2S expression and migrative ability than H460 cells. Phosphorylation of IκBα was not changed by treatment with the IKK-specific inhibitors PS1145 and SC514 in PC9 and H460 cells. Overexpression and knockdown of UBE2S in H460 and PC9 cells revealed that the protein levels of IκBα were inversely regulated. Immunoprecipitation, immunofluorescent staining, GST pull-down and in vitro binding assays revealed direct binding of UBE2S with IκBα. Nuclear P65 protein levels and luciferase assays showed that NF-κB signaling was regulated by UBE2S. The expression of epithelial-to-mesenchymal (EMT) markers and the migrative ability of lung adenocarcinoma cells were also regulated by UBE2S. A zebrafish xenograft tumor model showed a reduction in the metastasis of PC9 cells that was induced by UBE2S knockdown. CONCLUSIONS Higher UBE2S expression in lung adenocarcinomas may lead to increased binding with IκBα to activate NF-κB signaling and promote adenocarcinoma cell metastasis. UBE2S may serve as a potential therapeutic target for lung adenocarcinomas.

Abstract
Glioblastoma is the most common and lethal brain cancer globally. Clinically, this cancer has heterogenous molecular and clinical characteristics. Studies have shown that UBE2S is highly expressed in many cancers. But its expression profile in glioma, and the correlation with clinical outcomes is unknown. RNA sequencing data of glioma samples was downloaded from the Chinese Glioma Genome Atlas and The Cancer Genome Atlas. A total of 114 cases of glioma tissue samples (WHO grades II-IV) were used to conduct protein expression assays. The molecular and biological characteristics of UBE2S, and its prognostic value were analyzed. The results showed that high UBE2S expression was associated with a higher grade of glioma and PTEN mutations. In addition, UBE2S affected the degree of malignancy of glioma and the development of chemo-radiotherapy resistance. It was also found to be an independent predictor of worse survival of LGG patients. Furthermore, we identified five UBE2S ubiquitination sites and found that UBE2S was associated with Akt phosphorylation in malignant glioblastoma. The results also revealed that UBE2S expression was negatively correlated with 1p19q loss and IDH1 mutation; positively correlated with epidermal growth factor receptor amplification and PTEN mutation. This study demonstrates that UBE2S expression strongly correlates with glioma malignancy and resistance to chemo-radiotherapy. It is also a crucial biomarker of poor prognosis.

Abstract
At the heart of protein ubiquitination cascades, ubiquitin-conjugating enzymes (E2s) form reactive ubiquitin-thioester intermediates to enable efficient transfer of ubiquitin to cellular substrates. The precise regulation of E2s is thus crucial for cellular homeostasis, and their deregulation is frequently associated with tumorigenesis. In addition to driving substrate ubiquitination together with ubiquitin ligases (E3s), many E2s can also autoubiquitinate, thereby promoting their own proteasomal turnover. To investigate the mechanisms that balance these disparate activities, we dissected the regulatory dynamics of UBE2S, a human APC/C-associated E2 that ensures the faithful ubiquitination of cell cycle regulators during mitosis. We uncovered a dimeric state of UBE2S that confers autoinhibition by blocking a catalytically critical ubiquitin binding site. Dimerization is stimulated by the lysine-rich carboxyl-terminal extension of UBE2S that is also required for the recruitment of this E2 to the APC/C and is autoubiquitinated as substrate abundance becomes limiting. Consistent with this mechanism, we found that dimerization-deficient UBE2S turned over more rapidly in cells and did not promote mitotic slippage during prolonged drug-induced mitotic arrest. We propose that dimerization attenuates the autoubiquitination-induced turnover of UBE2S when the APC/C is not fully active. More broadly, our data illustrate how the use of mutually exclusive macromolecular interfaces enables modulation of both the activities and the abundance of E2s in cells to facilitate precise ubiquitin signaling.

Abstract
Purpose Ubiquitin-conjugating enzyme E2S (UBE2S) is important for the development and progression of several types of cancer. However, neither the role of UBE2S in pancreatic cancer nor its mechanism is clear. Methods We analyzed three GEO datasets to obtain 150 differentially expressed genes (DEGs) between pancreatic ductal adenocarcinoma (PDAC) and non-cancerous samples. Moreover, GSEA and mutation analysis were also done for UBE2S. The UBE2S expression in PDAC was measured by immunohistochemistry and qRT-PCR. Colony formation, scratch wound-healing and tumor growth assays were conducted to examine the effect of UBE2S on PDAC cells. Migration was detected using Transwell assay. UBE2S knockdown pancreatic cells were treated with proteasome inhibitor MG132. Immunofluorescence was undertaken for interaction between UBE2S and VHL. The expression of Snail and Twist1 and the changes of HIF-1α/STAT3 pathway were detected by Western blotting. Results The mRNA of UBE2S was significantly upregulated in human pancreatic cancer compared to normal tissues. Immunohistochemistry confirmed that the protein level of UBE2S increased in tissue microarrays (TMAs) and was associated with lymph nodes metastasis and distant metastasis. Conclusion UBE2S could enhance EMT by the VHL/HIF-1α/STAT3 pathway via the ubiquitin-proteasome system. Co-expression of CDC20 may represent a novel and promising therapeutic target for the patients with PDAC.

Abstract
Ubiquitin-conjugating enzymes (E2s) govern key aspects of ubiquitin signaling. Emerging evidence suggests that the activities of E2s are modulated by posttranslational modifications; the structural underpinnings, however, are largely unclear. Here, we unravel the structural basis and mechanistic consequences of a conserved autoubiquitination event near the catalytic center of E2s, using the human anaphase-promoting complex/cyclosome-associated UBE2S as a model system. Crystal structures we determined of the catalytic ubiquitin carrier protein domain combined with MD simulations reveal that the active-site region is malleable, which permits an adjacent ubiquitin acceptor site, Lys+5, to be ubiquitinated intramolecularly. We demonstrate by NMR that the Lys+5-linked ubiquitin inhibits UBE2S by obstructing its reloading with ubiquitin. By immunoprecipitation, quantitative mass spectrometry, and siRNA-and-rescue experiments we show that Lys+5 ubiquitination of UBE2S decreases during mitotic exit but does not influence proteasomal turnover of this E2. These findings suggest that UBE2S activity underlies inherent regulation during the cell cycle.

Abstract
Ubiquitin-conjugating enzyme E2S (UBE2S), a family of E2 protein in the ubiquitination process, is involved in development of various cancers. However, its role in lung adenocarcinoma, has not been well elucidated. In this report, we attempted to investigate expression and function of UBE2S in lung adenocarcinoma. Up-regulation of UBE2S at mRNA, and protein level, was observed in human cancer tissues and lung adenocarcinoma cells. Higher UBE2S expression correlated with poorer prognosis of lung adenocarcinoma patients. UBE2S expression was efficiently suppressed by lentivirus-mediated shRNA strategy in A549 cells, and UBE2S silencing led to reduced cell proliferation, colony formation, and enhanced apoptosis. Inverse results were observed, in UBE2S over-expressed H1299 cells. Microarray analysis indicated that a large number of genes were regulated by UBE2S, and p53 signaling pathway may be critical, to the role of UBE2S in cancer development. Together, UBE2S could be a potential target for lung adenocarcinoma.

Abstract
Previous study has shown that ubiquitin-conjugating enzyme E2 S (UBE2S) is highly expressed in various human cancers. In order to study the clinical value and potential function of UBE2S in hepatocellular carcinoma (HCC), three datasets from the Oncomine database and RNA-seq data from The Cancer Genome Atlas (TCGA) were analyzed. UBE2S expression was found to be significantly higher in HCC samples, which was supported with qPCR validation. Both Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses demonstrated that UBE2S co-expressed genes were involved in cell cycle and DNA replication. Survival analysis showed a significant reduction in overall survival of patients with high UBE2S expression from both the GSE14520 cohort and TCGA Liver hepatocellular carcinoma (LIHC) cohort. Furthermore, Gene set enrichment analysis (GSEA) revealed that high UBE2S expression in HCC patients is associated with increased expression in gene sets associated with decreased survival, increased metastasis and increased recurrence. Finally, qPCR results showed that UBE2S overexpression has diagnostic value in distinguishing between HCC and non-cancerous liver tissue, as the area under the curve (AUC) was 0.8095, and overexpression of UBE2S was significantly associated with decreased overall survival and disease-free survival in HCC patients. In conclusion, UBE2S may hold prognostic value in the treatment of HCC.

Abstract
The interferon-stimulated gene 15 ubiquitin-like modifier (ISG15) encodes an IFN-inducible, ubiquitin-like protein. The ISG15 protein forms conjugates with numerous cellular proteins that are involved in a multitude of cellular functions, including interferon-induced immune responses and the regulation of cellular protein turnover. The expression of ISG15 and ISG15-mediated conjugation has been implicated in a wide range of human tumors and cancer cell lines, but the roles of ISG15 in tumorigenesis and responses to anticancer treatments remain largely unknown. In this review, we discuss the findings of recent studies with regard to the role of ISG15 pathways in cancers of the digestive system.

Abstract
We previously reported that the dietary flavonoids, luteolin and quercetin, might inhibit the invasiveness of cervical cancer by reversing epithelial-mesenchymal transition (EMT) signaling. However, the regulatory mechanism exerted by luteolin and quercetin is still unclear. This study analyzed the invasiveness activation by ubiquitin E2S ligase (UBE2S) through EMT signaling and inhibition by luteolin and quercetin. We found that UBE2S expression was significantly higher in highly invasive A431 subgroup III (A431-III) than A431-parental (A431-P) cells. UBE2S small interfering (si)RNA knockdown and overexpression experiments showed that UBE2S increased the migratory and invasive abilities of cancer cells through EMT signaling. Luteolin and quercetin significantly inhibited UBE2S expression. UBE2S showed a negative correlation with von Hippel-Lindau (VHL) and a positive correlation with hypoxia-induced factor (Hif)-1α. Our findings suggest that high UBE2S in malignant cancers contributes to cell motility through EMT signaling and is reversed by luteolin and quercetin. UBE2S might contribute to Hif-1α signaling in cervical cancer. These results show the metastatic inhibition of cervical cancer by luteolin and quercetin through reducing UBE2S expression, and provide a functional role for UBE2S in the motility of cervical cancer. UBE2S could be a potential therapeutic target in cervical cancer.

Abstract
Genomic DNA is damaged at an extremely high frequency by both endogenous and environmental factors. An improper response to DNA damage can lead to genome instability, accelerate the aging process and ultimately cause various human diseases, including cancers and neurodegenerative disorders. The mechanisms that underlie the cellular DNA damage response (DDR) are complex and are regulated at many levels, including at the level of post-translational modification (PTM). Since the discovery of ubiquitin in 1975 and ubiquitylation as a form of PTM in the early 1980s, a number of ubiquitin-like modifiers (UBLs) have been identified, including small ubiquitin-like modifiers (SUMOs), neural precursor cell expressed, developmentally down-regulated 8 (NEDD8), interferon-stimulated gene 15 (ISG15), human leukocyte antigen (HLA)-F adjacent transcript 10 (FAT10), ubiquitin-fold modifier 1 (UFRM1), URM1 ubiquitin-related modifier-1 (URM1), autophagy-related protein 12 (ATG12), autophagy-related protein 8 (ATG8), fan ubiquitin-like protein 1 (FUB1) and histone mono-ubiquitylation 1 (HUB1). All of these modifiers have known roles in the cellular response to various forms of stress, and delineating their underlying molecular mechanisms and functions is fundamental in enhancing our understanding of human disease and longevity. To date, however, the molecular mechanisms and functions of these UBLs in the DDR remain largely unknown. This review summarizes the current status of PTMs by UBLs in the DDR and their implication in cancer diagnosis, therapy and drug discovery.

Abstract
Ubiquitin-conjugating enzyme E2S (UBE2S), a family of E2 protein in the ubiquitin-proteasome system, is highly expressed in several types of cancers; however, its roles in oral squamous cell carcinoma (OSCC) have not yet been well elucidated. The purpose of this study was to clarify the functional activities of UBE2S in OSCCs. We analyzed the expression levels of UBE2S in nine OSCC cell lines and primary OSCC tissues by quantitative reverse transcriptase-polymerase chain reaction, Western blotting, and immunohistochemistry (IHC). The correlations between UBE2S expression and clinical classifications of OSCCs were analyzed using the IHC scoring system. We also used UBE2S knockdown OSCC cells for functional assays (proliferation assay, flow cytometry, and Western blotting). UBE2S was overexpressed in OSCCs in vitro and in vivo and was correlated significantly (P < 0.05) with the primary tumoral size. The cellular growth was decreased and the cell-cycle was arrested in the G2/M phase in the UBE2S knockdown (shUBE2S) cells. The expression level of P21, a target of the ubiquitin-proteasome system, was increased in the shUBE2S cells because of lower anaphase activity that promotes complex subunit 3 (APC3), an E3 ubiquitin ligase, compared with shMock cells. These findings might promote the understanding of the relationship between UBE2S overexpression and oral cancer proliferation, indicating that UBE2S would be a potential biomarker of and therapeutic target in OSCCs.

Abstract
Glioblastoma multiforme (GBM) is the most common primary malignant brain cancer in adults. However, the molecular events underlying carcinogenesis and their interplay remain elusive. Here, we report that the stability of Ubiquitin-conjugating enzyme E2S (UBE2S) is regulated by the PTEN/Akt pathway and that its degradation depends on the ubiquitin-proteasome system. Mechanistically, Akt1 physically interacted with and phosphorylated UBE2S at Thr 152, enhancing its stability by inhibiting proteasomal degradation. Additionally, accumulated UBE2S was found to be associated with the components of the non-homologous end-joining (NHEJ) complex and participated in the NHEJ-mediated DNA repair process. The association of Ku70 with UBE2S was enhanced, and the complex was recruited to double-stranded break (DSB) sites in response to etoposide treatment. Furthermore, knockdown of UBE2S expression inhibited NHEJ-mediated DSB repair and rendered glioblastoma cells more sensitive to chemotherapy. Overall, our findings provide a novel drug target that may serve as the rationale for the development of a new therapeutic approach.

Abstract
OBJECTIVE To explore the correlations of circulating tumor cells (CTCs) and disseminated tumor cells (DTCs) with the clinicopathological characteristics, prognostic events, and survival outcomes in esophageal cancer (EC) patients. METHODS The PubMed, Web of Science, Embase database and Cochrane database were searched for studies reporting the outcomes of interest. The studies were selected according to established inclusion/exclusion criteria. Meta-analysis of the studies was performed using Review Manager 5.3 and Stata12.0 software with the odds ratio (OR), risk ratio (RR) , hazard ratio (HR) , and 95% confidence interval (95% CI) as the effect indexes. RESULTS Nineteen studies involving a total of 1766 patients were included in the analysis. Significant correlations of CTCs and DTCs were found with the clinicopathological parameters including the tumor stage (OR=1.95), depth of invasion (OR=1.99), lymph node metastasis (OR=2.44SEN), distal metastasis (OR=5.98SEN), histological differentiation (OR=1.67) and lymphovascular invasion (OR=4.48). CTCs and DTCs were also correlated with the prognostic events including relapse (RR=6.86SEN) and metastasis (RR=3.22) and with the survival outcomes including the overall survival (OS) overall analysis (HR=3.46) and disease-free survival/progression-free survival (DFS/PFS) overall analysis (HR=3.00). CONCLUSION CTCs and DTCs are significantly associated with an advanced tumor stage, depth of tumor invasion, lymph node metastasis, distant metastasis before therapy, differentiation, lymphovascular invasion, relapse and metastasis in patients with EC. They are also significantly correlated with a poorer survival for OS and DFS/PFS to serve as clinical and prognostic predictors in patients with EC.

Abstract
Knowledge of potential tumor markers may improve chemotherapeutic efficacy. Interleukin-6 (IL-6) expression in local tumor tissues is associated with cancer progression and poor prognosis in variety of cancer types. The aim of the present study was to investigate the role and potential application of IL-6 in determining the prognosis of esophageal carcinoma. KYSE170 and TE13 esophageal cancer cell lines were used to conduct cell- and animal-based experiments investigating biological changes and tumor behavior. Immunohistochemical analysis revealed that 70–80% of cancer cells exhibited positive staining for IL-6, compared with <15% of non-malignant epithelial cells. These immunohistochemical results were consistent with the mRNA expression levels detetced. The IL-6 silencing vector significantly reduced invasion and proliferation of the two cell lines and attenuated tumor growth in xenograft mouse models (P<0.05). The IL-6 silencing vector markedly reduced the presence of Ki-67 (a typical proliferation marker) and microvessel density, indicating that downregulation of IL-6 levels may greatly affect tumor growth and inhibition. The IL-6 silencing vector increased E-cadherin and matrix metalloproteinase (MMP)-9 expression levels in the two esophageal carcinoma cell lines. This vector also regulated the release of IL-6 in cell supernatant and serum in KYSE170- and TE13-tumor-bearing mice. The secretion of vascular endothelial growth factor and cluster of differentiation 31 (a nuclear protein) immunoreactive molecules were also reduced by the IL-6 silencing vector. Therefore, IL-6 may be an important trigger in the progression of angiogenesis and endothelial tube formation within the tumor, and targeting IL-6 may be a promising strategy for the treatment of esophageal cancer.

Abstract
Background Systematic analysis of cancer gene-expression patterns using high-throughput transcriptional profiling technologies has led to the discovery and publication of hundreds of gene-expression signatures. However, few public signature values have been cross-validated over multiple studies for the prediction of cancer prognosis and chemosensitivity in the neoadjuvant setting. Methods To analyze the prognostic and predictive values of publicly available signatures, we have implemented a systematic method for high-throughput and efficient validation of a large number of datasets and gene-expression signatures. Using this method, we performed a meta-analysis including 351 publicly available signatures, 37,000 random signatures, and 31 breast cancer datasets. Survival analyses and pathologic responses were used to assess prediction of prognosis, chemoresponsiveness, and chemo-drug sensitivity. Results Among 31 breast cancer datasets and 351 public signatures, we identified 22 validation datasets, two robust prognostic signatures (BRmet50 and PMID18271932Sig33) in breast cancer and one signature (PMID20813035Sig137) specific for prognosis prediction in patients with ER-negative tumors. The 22 validation datasets demonstrated enhanced ability to distinguish cancer gene profiles from random gene profiles. Both prognostic signatures are composed of genes associated with TP53 mutations and were able to stratify the good and poor prognostic groups successfully in 82%and 68% of the 22 validation datasets, respectively. We then assessed the abilities of the two signatures to predict treatment responses of breast cancer patients treated with commonly used chemotherapeutic regimens. Both BRmet50 and PMID18271932Sig33 retrospectively identified those patients with an insensitive response to neoadjuvant chemotherapy (mean positive predictive values 85%-88%). Among those patients predicted to be treatment sensitive, distant relapse-free survival (DRFS) was improved (negative predictive values 87%-88%). BRmet50 was further shown to prospectively predict taxane-anthracycline sensitivity in patients with HER2-negative (HER2-) breast cancer. Conclusions We have developed and applied a high-throughput screening method for public cancer signature validation. Using this method, we identified appropriate datasets for cross-validation and two robust signatures that differentiate TP53 mutation status and have prognostic and predictive value for breast cancer patients.

Abstract
Background The identification of potential tumor markers can improve therapeutic planning and patient management. The aim of this study was to highlight the significance of IL-6 in esophageal squamous cell carcinoma (SCC). Methods We retrospectively analyzed the clinical outcomes of 173 patients with esophageal SCC, and examined the correlation between IL-6 levels and clinical outcomes in esophageal cancer patients. Furthermore, the human esophageal SCC cell line CE81T was selected for cellular and animal experiments to investigate changes in tumor behavior and treatment response after manipulation of IL-6 expression. Results In clinical outcome analysis, positive IL-6 staining and poor treatment response was significantly associated with shorter survival. Furthermore, the frequency of IL-6 immunoreactivity was significantly higher in esophageal cancer specimens than in non-malignant epithelium, and this staining was positively linked to the development of distant metastasis (p = 0.0003) and lower treatment response rates (p = 0.0001).By ELISA analysis, IL-6 serum levels were significantly elevated in patients developing disease failure.When IL-6 expression was inhibited, aggressive tumor behavior and radiation resistance could be overcome in vitro and in vivo. The underlying changes included increased cell death, less epithelial-mesenchymal transition and attenuated STAT3 activation. IL-6 inhibition was also associated with attenuated angiogenesis in tumor-bearing mice. Conclusions IL-6 was significantly associated with poor prognosis in patients with esophageal cancer. Targeting this cytokine could be a promising strategy for treatment of esophageal cancer, as evidenced by inhibition of aggressive tumor behavior and treatment resistance.

Furthermore, a human esophageal SCC cell line, CE81T, was selected for cellular and animal experiments to investigate changes in tumor behavior and treatment response after the manipulation of DNMT3b expression. RESULTS The incidence of nuclear DNMT3b immunoreactivity in esophageal cancer specimens was significantly higher than in nonmalignant epithelium, and this incidence was linked positively to developing distant metastasis (56% in localized disease vs 80% in distant metastasis; P = .002). Furthermore, increased expression of DNMT3b was linked significantly to lower treatment response rates (P = .002) and reduced survival rates (P = .000). Inhibition of DNMT3b expression resulted in slower cellular proliferation, increased cell death, a less invasive capacity, and less epithelial-mesenchymal-transition changes. Moreover, DNMT3b silencing vectors sensitized esophageal cancer cells to irradiation and cisplatin treatment. The current results also indicated that constitutional activation of signal transducer and activator of transcription 3 (STAT3) signaling associated with inhibited expression of suppressor of cytokine signaling 3 (SOCS3) may be the mechanism underlying more aggressive tumor growth in DNMT3b-positive esophageal cancer. CONCLUSIONS DNMT3b was linked significantly to a poor prognosis for patients with esophageal cancer. Moreover, the current results indicated that targeting this enzyme may be a promising strategy for treating esophageal cancer, as evidenced by inhibited aggressive tumor behavior and treatment resistance.

Abstract
Interleukin (IL)-1 beta has been reported to be a marker of shorter survival in gastric and colorectal adenocarcinoma. In the present study, we examined the potential role and prognostic value of IL-1 beta in esophageal squamous cell carcinoma (SCC). Human esophageal SCC cell line, CE81T, was selected for cellular and animal experiments, in which biological changes after experimental manipulation of IL-1 beta signaling were explored, including tumor growth, invasion capacity, and the sensitivity to treatment. Moreover, 147 esophageal SCC samples were analyzed using immunohistochemical staining to correlate the expression of IL-1 beta with clinical outcome. Our data revealed that IL-1 beta was significantly overexpressed both at mRNA and protein levels in cancer specimens compared to nonmalignant tissues. When IL-1 beta signaling was blocked, tumor growth, invasion ability, and treatment resistance were attenuated. Activation of NF-kappa B, increase of E2-EPF ubiquitin carrier protein and subsequent epithelial-mesenchymal transition might be the underlying mechanisms of the more aggressive tumor growth in IL-1 beta-positive esophageal cancer. The immunochemistry findings indicate that positivity staining of IL-1 beta correlated significantly with higher clinical stage, lower response rate to concurrent chemoradiotherapy (CCRT), and higher recurrence rate after curative treatment. Moreover, IL-1 beta was a significant predictor of survival in patients undergoing surgical intervention or definite CCRT. In conclusion, IL-1 beta is significantly linked to poor prognosis for patients with esophageal cancer and may be a promising molecular target for therapeutic intervention for esophageal SCC.

Abstract
Aims Transforming growth factor-β (TGF-β), fascin, nuclear factor-kappa B (NF-κB) p105, protein-kinase C-zeta (PKC-ζ), partioning-defective protein-6 (Par-6), E-cadherin and vimentin are tumor promoting molecules through mechanisms involved in cell dedifferentiation. In soft tissue sarcomas, their expression profile is poorly defined and their significance is uncertain. We aimed to investigate the prognostic impact of TGF-β1, NF-κB p105, PKC-ζ, Par-6α, E-cadherin and vimentin in non-gastrointestinal stromal tumor soft tissue sarcomas (non-GIST STSs). Patients and Methods Tumor samples and clinical data from 249 patients with non-GIST STS were obtained, and tissue microarrays (TMAs) were constructed for each specimen. Immunohistochemistry (IHC) was used to evaluate marker expression in tumor cells. Results In univariate analysis, the expression levels of TGF-β1 (P = 0.016), fascin (P = 0.006), NF-κB p105 (P = 0.022) and PKC-ζ, (P = 0.042) were significant indicators for disease specific survival (DSS). In the multivariate analysis, high TGF-β1 expression was an independent negative prognostic factor for DSS (HR = 1.6, 95% CI = 1.1–2.4, P = 0.019) in addition to tumor depth, malignancy grade, metastasis at diagnosis, surgery and positive resection margins. Conclusion Expression of TGF-β1 was significantly associated with aggressive behavior and shorter DSS in non-GIST STSs.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy is widely accepted for the treatment of localized rectal cancer. Although peroxiredoxin I (PrxI) and p53 have been implicated in carcinogenesis and cancer treatment, the role of PrxI and its interaction with p53 in the prognosis and treatment response of rectal cancer remain relatively unstudied. METHODS AND MATERIALS In the present study, we examined the levels of PrxI and p53 in rectal cancer patients using membrane arrays and compared them with normal population samples. To demonstrate the biologic changes after manipulation of PrxI expression, we established stable transfectants of HCT-116 (wild-type p53) and HT-29 (mutant p53) cells with a PrxI silencing vector. The predictive capacities of PrxI and p53 were also assessed by relating the immunohistochemical staining of a retrospective series of rectal cancer cases to the clinical outcome. RESULTS The membrane array and immunochemical staining data showed that PrxI, but not p53, was significantly associated with the tumor burden. Our immunochemistry findings further indicated that PrxI positivity was linked to a poor response to neoadjuvant therapy and worse survival. In cellular and animal experiments, the inhibition of PrxI significantly decreased tumor growth and sensitized the tumor to irradiation, as indicated by a lower capacity to scavenge reactive oxygen species and more extensive DNA damage. The p53 status might have contributed to the difference between HCT-116 and HT-29 after knockdown of PrxI. CONCLUSION According to our data, the level of PrxI combined with the p53 status is relevant to the prognosis and the treatment response. We suggested that PrxI might be a new biomarker for rectal cancer.
