Gao X, Lu M, Xu W, Liu C, Wu J. miR-195 inhibits esophageal cancer cell proliferation and promotes apoptosis by downregulating YAP1. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2019; 12:275-281. [PMID: 31933743 PMCID: PMC6943995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Accepted: 10/29/2018] [Indexed: 06/10/2023]
Abstract
OBJECTIVE Yes-associated protein 1 (YAP1) regulates a variety of genes related to cell proliferation, cycle and apoptosis, and plays a role in the pathogenesis of esophageal cancer. It was found that the expression of miR-195 was significantly decreased in esophageal cancer tissues, suggesting its anti-cancer effect. Bioinformatics analysis revealed the targeted relationship between miR-195 and the 3'-UTR of YAP1. This study investigated the role of miR-195 in regulating YAP1 expression and affecting proliferation and apoptosis of esophageal cancer cells. METHODS The tumor tissue and the adjacent tissue of patients with esophageal cancer were collected to detect the expressions of miR-195 and YAP1. Dual luciferase reporter gene assay was adopted to validate the targeted regulation between miR-195 and YAP1. Esophageal cancer EC9706 cells and normal esophageal epithelial HEEC cells were cultured in vitro to measure the expression of miR-195 and YAP1. EC9706 cells were divided into miR-NC group and miR-195 mimic group followed by analysis of cell apoptosis by flow cytometry and cell proliferation by EdU staining. RESULTS Compared with adjacent tissues, miR-195 was significantly decreased, while YAP1 mRNA and protein were significantly upregulated in esophageal cancer tissues. Dual luciferase reporter gene assay confirmed that there was a targeted relationship between miR-195 and YAP1. Compared with HEEC cells, miR-195 expression was declined, whereas YAP1 was elevated in EC9706 cells. Transfection of miR-195 mimic significantly downregulated YAP1 expression, resulting in increased apoptosis and decreased proliferation of EC9706 cells. CONCLUSION Decreased expression of miR-195 plays a regulatory role in increasing YAP1 expression and promoting the pathogenesis of esophageal cancer. Elevation of miR-195 inhibites the expression of YAP1, restrains cell proliferation, and promotes cell apoptosis.

Xing S, Zheng X, Zeng T, Zeng MS, Zhong Q, Cao YS, Pan KL, Wei C, Hou F, Liu WL. Chitinase 3-like 1 secreted by peritumoral macrophages in esophageal squamous cell carcinoma is a favorable prognostic factor for survival. World J Gastroenterol 2017; 23:7693-7704. [PMID: 29209110 PMCID: PMC5703929 DOI: 10.3748/wjg.v23.i43.7693] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Revised: 09/13/2017] [Accepted: 09/26/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To identify whether chitinase 3-like 1 (CHI3L1) serves as a suitable biomarker for the prognosis of esophageal squamous cell carcinoma (ESCC) and to analyze this protein’s cellular source.
METHODS An ELISA was conducted to detect the concentration of CHI3L1 in the serum of 150 ESCC patients diagnosed between January 2001 and February 2005. The prognostic relevance of CHI3L1 was evaluated by a Kaplan-Meier and Cox regression analysis. The immunohistochemistry was reanalyzed, and fluorescent staining was utilized to explore the cellular origins of CHI3L1. We stimulated monocyte-derived macrophages (MDMs) with either IL-6 or the supernatant of the ESCC cell line Eca-109 and later investigated the level of CHI3L1 by qPCR and ELISA.
RESULTS The level of serum CHI3L1 was higher in older patients (≥ 60) than in patients under the age of 60 (P = 0.001). The patients with higher levels of CHI3L1 had a significantly shorter overall survival, whereas the traditional markers, carcinoembryonic antigen and squamous cell carcinoma antigen, were less effective (P > 0.05). A multivariate Cox analysis (P = 0.001) indicated that CHI3L1 was an independent prognostic factor for ESCC patients. Peritumoral macrophages in ESCC exhibited high levels of CHI3L1. Interleukin-6 (IL-6) and the supernatant of Eca-109 containing IL-6 stimulated MDMs to secrete CHI3L1. The serum concentration of CHI3L1 in the ESCC patients showed a weak correlation with the laboratory inflammatory parameters neutrophil (NEU, P = 0.045), neutrophil/lymphocyte rate (NLR, P = 0.016), and C-reactive protein (CRP, P < 0.001).
CONCLUSION Our study first established a connection between the pretreated CHI3L1 and patients with ESCC, and the serum CHI3L1 was primarily secreted by ESCC-surrounded macrophages.

Abstract
The roles of secreted frizzled-related protein-1 (SFRP1) and β-catenin in human cancer have been widely studied, and it has recently been demonstrated that these proteins are associated with numerous human carcinomas. However, their clinical significance in glioblastoma multiforme (GBM) has not been examined. The current study aimed to analyze the correlation between the expression of SFRP1 and β-catenin, and clinicopathological characteristics in GBM patients. The expression of SFRP1 and β-catenin was assessed by immunohistochemistry in 113 samples of GBM and 40 normal brain tissues. Compared with normal brain tissues, GBM tissues exhibited significantly lower expression of SFRP1, and higher expression of β-catenin (both P<0.05). A Kaplan-Meier analysis revealed that patients with positive SFRP1 expression had a significantly longer overall survival (OS) time relative to those with negative SFRP1 expression (P<0.000), and that patients with positive β-catenin expression had a shorter OS time than those with negative β-catenin expression (P<0.000). A multivariate Cox regression analysis indicated that adjuvant treatment, SFRP1 expression and β-catenin expression were independent prognostic factors for OS (P<0.000, P=0.008 and P=0.001, respectively) in patients with GBM. The current data suggest that expression of SFRP1 and β-catenin may be considered significant prognostic indicators for patients with GBM.

Abstract
β-catenin (CTNNB1), an oncogene/onco-protein and an adhesion molecule is a key effector in colorectal cancer (CRC). Its activation, and subsequent up-regulation of Wnt-signaling, is an important event in the development of certain human cancers including CRC. Mutations in the β-catenin gene in the region of serine-threonine glycogen kinase (GSK)-3β phosphorylation target sites have been identified in colorectal cancer in humans. In the current study, we investigated 60 sporadic colorectal adenocarcinomas along with adjoining and normal mucosa cases in humans for β-catenin mutations. Thirteen of sixty colorectal tumors from humans had point mutations with a frequency of 21.66% at codons 24, 26, 27, 32, 34, 35, 41, 42,43, 46, 49, 54, 55, or 67 sites which are mutated in colorectal cancer and some of these sites in other cancers. Thus, there appears to be a key involvement of β-catenin activation in human colorectal carcinogenesis. mRNA expression analysis using q-Real Time PCR showed 21.5-fold up-regulation of β-catenin mRNA in tumor tissue compared to normal and adjoining mucosa. Protein expression analysis using immunohistochemistry, confocal microscopy, and Western blot confirmed aberrant accumulation of β-catenin protein along the nucleus and cytoplasm following mutation. The observed mutations and up-regulation of mRNA in tumors, and the increased expression of β-catenin protein in CRC suggest that these alterations are early and prognostic events in sporadic colorectal carcinogenesis in humans. © 2015 Wiley Periodicals, Inc.

Abstract
Cancer is the second leading cause of deaths worldwide. Despite concerted efforts to improve the current therapies, the prognosis of cancer remains dismal. Highly selective or specific blocking of only one of the signaling pathways has been associated with limited or sporadic responses. Using targeted agents to inhibit multiple signaling pathways has emerged as a new paradigm for anticancer treatment. Icariside II, a flavonol glycoside, is one of the major components of Traditional Chinese Medicine Herba epimedii and possesses multiple biological and pharmacological properties including anti-inflammatory, anti-osteoporosis, anti-oxidant, anti-aging, and anticancer activities. Recently, the anticancer activity of Icariside II has been extensively investigated. Here, in this review, our aim is to give our perspective on the current status of Icariside II, and discuss its natural sources, anticancer activity, molecular targets and the mechanisms of action with specific emphasis on apoptosis pathways which may help the further design and conduct of preclinical and clinical trials. Icariside II has been found to induce apoptosis in various human cancer cell lines of different origin by targeting multiple signaling pathways including STAT3, PI3K/AKT, MAPK/ERK, COX-2/PGE2 and β-Catenin which are frequently deregulated in cancers, suggesting that this collective activity rather than just a single effect may play an important role in developing Icariside II into a potential lead compound for anticancer therapy. This review suggests that Icariside II provides a novel opportunity for treatment of cancers, but additional investigations and clinical trials are still required to fully understand the mechanism of therapeutic effects to further validate it in anti-tumor therapy.

Abstract
In this study, we analyzed the microRNA (miRNA) expression profile of 119 paired ESCC samples by microarray and identified a four-miRNA signature that predicted patient survival. The signature derived from the training set (n=60) had a good prognostic value in the test set (n=59) and the independent cohort (n=58), indicating the replicability of its prognostic value. Furthermore, the stratified analysis showed that the signature could predict the survival of TNM stage II and stage III patients, indicating that the four-miRNA signature could help to more accurately predict ESCC patient survival.

Abstract
OBJECTIVES The aim of the present study was to explore mechanisms underlying the effects of down-regulating β-catenin expression on esophageal carcinoma (EC) cells. METHODS Cell cycle distribution and apoptosis were determined using flow cytometry and annexin V apoptosis assay, respectively. Transmission electron microscopy (TEM) was used to examine changes in ultrastructure, while expression of cyclin D1 protein and mRNA was detected by western blot and real-time PCR. Proliferating cell nuclear antigen (PCNA) and extracellular signal-regulated kinase (ERK) 1/2 were evaluated by Western blot analysis. PCNA labeling index (LI) was determined by immunocytochemistry. RESULTS Compared with pGen-3-con transfected and Eca-109 cells, the percentage of G0/G1-phase pGen-3-CTNNB1 transfected cells was obviously increased (P<0.05), with no significant difference among the three groups with regard to apoptosis (P>0.05). pGen-3-CTNNB1 transfected cells exhibited obvious decrease in cyclin D1 mRNA and protein expression (P<0.05) and the ultrastructure of Eca-109 cells underwent a significant change after being transfected with pGen-3-CTNNB1, suggesting that down-regulating β-catenin expression can promote the differentiation and maturation. The expression of PCNA and the ERKI/2 phosphorylation state were also down-regulated in pGen-3-CTNNB1 transfected cells (P<0.05). At the same time, the PCNA labeling index was decreased accordingly (P<0.05). CONCLUSION Inhibition of EC Eca-109 cellproliferation by down-regulating β-catenin expression could improve cell ultrastructure by mediating blockade in G0/G1 through inhibiting cyclin D1, PCNA and the MAPK pathway (p-ERK1/2).

Abstract
AIM: To study the expression of β-catenin in esophageal squamous cell carcinoma (ESCC) at stage T2-3N0M0 and its relation with the prognosis of ESCC patients.
METHODS: Expression of β-catenin in 227 ESCC specimens was detected by immunohistochemistry (IHC). A reproducible semi-quantitative method which takes both staining percentage and intensity into account was applied in IHC scoring, and receiver operating characteristic curve analysis was used to select the cut-off score for high or low IHC reactivity. Then, correlation of β-catenin expression with clinicopathological features and prognosis of ESCC patients was determined.
RESULTS: No significant correlation was observed between β-catenin expression and clinicopathological parameters in terms of gender, age, tumor size, tumor grade, tumor location, depth of invasion and pathological stage. The Kaplan-Meier survival curve showed that the up-regulated expression of β-catenin indicated a poorer post-operative survival rate of ESCC patients at stage T2-3N0M0 (P = 0.004), especially of those with T3 lesions (P = 0.014) or with stage IIB diseases (P = 0.007). Multivariate analysis also confirmed that β-catenin was an independent prognostic factor for the overall survival rate of ESCC patients at stage T2-3N0M0 (relative risk = 1.642, 95% CI: 1.159-2.327, P = 0.005).
CONCLUSION: Elevated β-catenin expression level may be an adverse indicator for the prognosis of ESCC patients at stage T2-3N0M0, especially for those with T3 lesions or stage IIB diseases.

Abstract
The aim of this study was to investigate the correlation between Wnt1/beta-catenin expression and the clinicopathologic features and prognosis of patients with esophageal squamous cell carcinoma (ESCC). The mRNA and protein expression levels of Wnt1/beta-catenin genes in 70 ESCC and 15 adjacent noncancerous paraffin-embedded samples were determined by real-time quantitative polymerase chain reaction and immunohistochemical staining. The mRNA expression level of Wnt1/beta-catenin in ESCC was significantly higher than that in the adjacent noncancerous tissues (1.9934 +/- 1.9888 vs. 0.8863 +/- 0.665, p = 0.0184; 0.2854 +/- 0.1298 vs. 0.0128 +/- 0.0158, p = 0.0000, respectively), and the overexpression of Wnt1/beta-catenin mRNA was aggressively associated with lymph node metastasis and advanced pathological stage (p < 0.0001). The protein expression level of Wnt1/beta-catenin was also significantly higher than that in the adjacent noncancerous tissues (0.3830 +/- 0.0947 vs. 0.2721 +/- 0.1474, p = 0.0002; 0.2835 +/- 0.0844 vs. 0.2352 +/- 0.0670, p = 0.0210, respectively); however, the overexpression was not associated with clinicopathologic characteristics. Meanwhile, the protein expression level of Wnt1 had no relevance with that of beta-catenin. The overexpression of Wnt1/beta-catenin might be an important molecular marker to predict the clinicopathologic stage and prognosis of ESCC, and the level of Wnt1/beta-catenin mRNA was conversely correlated with lymph node metastasis and advanced pathological stage. The overexpression of Wnt1/beta-catenin mRNA should also predict poor prognosis of ESCC; however, it might not be an independent prognostic factor.

Abstract
beta-catenin has emerged as a key regulator of Wnt signaling pathway, which plays an important role in the development and progression of various cancers. Its accumulation in nucleus of the esophagus squamous epithelium might be the crucial step for the carcinogenesis of esophageal squamous cell carcinoma (ESCC). To detect the proteins correlated with beta-catenin function, we used the established cell lines of pGen-3-con (Eca109 cells transfected by control vector) and pGen-3-CTNNB1 (Eca109 cells transfected by beta-catenin siRNA) as cell models for further analysis. Two-dimensional gel electrophoresis technology was performed to separate the proteins of pGen-3-con and pGen-3-CTNNB1 cell lines, respectively. The differential protein spots were analyzed by software analysis, subjected to in-gel digestion, and identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Consequently, 13 differentially expressed proteins between the two cell lines were identified, of which 14-3-3sigma, prohibitin, and nm23-H1 were further verified by western blotting and quantitative real-time reverse transcriptase-polymerase chain reaction. Then, the tissue microarray and immunohistochemical analysis were employed to research their relationship in ESCC and their corresponding normal mucosa tissues. The upregulation of prohibitin or the downregulation of 14-3-3sigma and nm23-H1 proteins was significantly associated with the proliferation, invasion depth, and lymph node metastasis of ESCC. There were statistically significant correlations between the expression of beta-catenin and the three proteins. The results presented here might provide potential protein markers to elucidate the mechanism of beta-catenin-mediated biologic characteristics for ESCC.
