Abstract
Esophageal adenocarcinoma exhibits one of the highest mortality rates among all cancer entities. Multimodal therapy strategies have improved patients' survival significantly. However, patients in early stages are currently limited to receiving only local therapies, even though some patients within this group showcase short survival periods. Until now, there has been no widely established clinically used biomarker to detect these high-risk patients. Telomerase reverse transcriptase (TERT), a gene encoding a crucial subunit of the telomerase enzyme, plays a significant role in establishing cancer cell immortality and is under suspicion for its potential contribution to tumor progression. Therefore, we aimed to evaluate the clinical relevance of the TERT amplification status. We included 643 patients with esophageal adenocarcinoma, who underwent Ivor-Lewis esophagectomy at the University Hospital of Cologne. The TERT amplification status was characterized using fluorescence in situ hybridization. Clinicopathological values and patients' overall survival were compared between patients with and without TERT amplification. Further sub-cohort analyses were conducted for patients with pT1N0-3 tumor stage. Eighty-One patients (12.6%) exhibited TERT amplification. Patients with amplified TERT showed significantly worse overall survival (median OS: 22.6 vs. 36.8 months, p = 0.009). Interestingly, TERT amplification could be characterized as an independent risk factor for worse overall survival in multivariate analysis in patients with pT1N0-3 tumor stage (HR = 2.440, 95% CI 1.095-5.440, p = 0.029). In this study, we describe the TERT amplification status as an independent risk factor for worse survival in patients diagnosed with esophageal adenocarcinoma at pT1N0-3 tumor stage, encompassing cases involving tumor infiltration of the lamina propria, muscularis mucosae, and/or submucosa. Based on our findings, we put forth the proposition that evaluating the TERT amplification status may serve as a valuable tool in identifying a specific subgroup of patients, namely those with TERT amplification and pT1N0-3 tumor-stage esophageal adenocarcinoma. The patients of this subgroup could potentially benefit from enhanced follow-up protocols, more aggressive treatment approaches, or possible targeted TERT inhibition therapies, all aimed at improving their overall clinical outcomes.

Associations of telomerase reverse transcriptase rs10069690 and rs2736100 polymorphisms with papillary thyroid carcinoma. Eur J Cancer Prev 2021; 29:259-265. [PMID: 31651569 DOI: 10.1097/cej.0000000000000536] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/19/2022]
Abstract
Papillary thyroid carcinoma is one of the most common endocrine malignancies. Telomerase reverse transcriptase rs10069690 and rs2736100 polymorphisms have been studied in thyroid carcinomas with different ethnicity, but the results were inconsistent. Therefore, we evaluated the relationship between rs10069690 and rs2736100 polymorphisms and papillary thyroid carcinoma risk and furtherly investigated the associations of these polymorphisms with stimulated thyroglobulin (sTg) positivity and adverse reactions of I treatment in papillary thyroid carcinoma. Four hundred thirty-six papillary thyroid carcinoma patients and 345 controls of Chinese Han population were included in our study. Rs10069690 and rs2736100 were genotyped using improved multiple ligase detection reactions. Analysis of inheritance model was performed using the unconditional logistic regression. In our study, rs10069690 and rs2736100 were associated with papillary thyroid carcinoma risk, especially in females over 45 years of age (P = 0.002 and P = 0.032, respectively). Rs10069690 was associated with sTg positivity and with an rs10069690-related occurrence risk order of thyroglobulin antibody (Tg-Ab)(+) + Tg(+) > Tg-Ab(+) + sTg(-) > Tg-Ab(-) + sTg(+). Patients with the homozygous TT genotype of rs10069690 had an increased risk of neck discomfort (P = 0.033), while the homozygous CC genotype of rs2736100 had a decreased risk of gastrointestinal toxicity (P = 0.048). Our data demonstrated that rs10069690 and rs2736100 might be bio-indicators related to papillary thyroid carcinoma risk in females over 45 years of age and I treatment-related toxicity. In addition, rs10069690 may be a predictor of bad clinicopathological features and poor prognosis from a serological point of view.

Abstract
Background: Myelodysplastic Syndromes (MDS)are clonal hematologic disorders characterized by genetic instability and ineffective hematopoiesis associated with telomere dysfunction. We aimed at investigating the association between the rs2242652 single nucleotide variant of the TERT gene and susceptibility for MDS, as well as its prognostic impact and relation to disease phenotype. Methods: Genotyping analysis was carried on 100 MDS patients recruited at Mansoura Oncology center, in addition to 100 healthy subjects for detection of rs2242652 variant of TERT gene on chromosome 5 by real time PCR following the protocol of Custom TaqMan® SNP Genotyping. Results: The rs2242652 TERT genetic polymorphism was associated with an increased risk of MDS (odds ratios 2.6 for genotype GA, 6.4 for genotype AA). The majority of AA homozygous mutant variant were associated pancytopenia (88%), poor risk cytogenetics (92%) and High/very high IPSS-R score (88%). At the end of follow-up (median 30 months), 14% of the cases transformed to secondary AML. The rate of leukemic transformation was significantly associated with the mutant AA genotype (93% of transformed cases, 52% of AA genotype cases; P< 0.0001). Survival outcome was inferior in AA mutant genotype (median 14 months, 95% CI: 12-16 months) to the GA genotype (median 30 months, 95% CI: 26-33 months) and those of the GG genotype (median not reached), P<0.001. Conclusion: Our study shows an intriguing and previously unrecognized association between rs2242652 TERT mutation and MDS risk. The presence of rs2242652 mutation defines a subgroup of patients with aggressive disease phenotype and dismal outcome. Further research is recommended to elucidate underlying pathologic mechanisms and to define an efficient therapeutic target.

Time series expression pattern of key genes reveals the molecular process of esophageal cancer. Biosci Rep 2021; 40:222161. [PMID: 32068233 PMCID: PMC7048673 DOI: 10.1042/bsr20191985] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 11/24/2019] [Accepted: 12/16/2019] [Indexed: 12/18/2022] Open
Abstract
Background: Esophageal cancer is one of the most poorly diagnosed and fatal cancers in the world. Although a series of studies on esophageal cancer have been reported, the molecular pathogenesis of the disease is still elusive. Aim: To investigate the molecular process of esophageal cancer comprehensively and deeply. Methods: Differential expression analysis was performed to identify differentially expressed genes (DEGs) in different stages of esophageal cancer. Then exacting gene interaction modules and hub genes were identified in module interaction network. Further, though survival analysis, methylation analysis, pivot analysis, and enrichment analysis, some important molecules and related function or pathway were identified to elucidate potential mechanism in esophageal cancer. Results: A total of 7457 DEGs and 14 gene interaction modules were identified. These module genes were significantly involved in the positive regulation of protein transport, gastric acid secretion, insulin-like growth factor receptor binding and other biological processes (BPs), as well as p53 signaling pathway, ERBB signaling pathway and epidermal growth factor receptor (EGFR) signaling pathway. Then, transcription factors (TFs) (including HIF1A) and ncRNAs (including CRNDE and hsa-mir-330-3p) significantly regulate dysfunction modules were identified. Further, survival analysis showed that GNGT2 was closely related to survival of esophageal cancer. And DEGs with strong methylation regulation ability were identified, including SST and SH3GL2. Conclusion: These works not only help us to reveal the potential regulatory factors in the development of disease, but also deepen our understanding of its deterioration mechanism.

Abstract
Background Esophageal cancer (EC) is the leading cause of cancer‐related mortality worldwide. The underlying genetic risk factors remain unclear. The association between gene growth hormone receptor (GHR) and phospholipase C epsilon 1 (PLCE1) polymorphisms and the EC risk were identified in this study. Methods A total of 506 EC cases and 507 controls were included in this research. Two SNPs (rs6898743 of GHR and rs2274223 of PLCE1) were selected and genotyped. The associations between gene polymorphisms and the EC risk were assessed by logistic regression analysis. The databases RegulomeDB, GTEx, and UALCAN were used for functional annotations. Results In the allelic frequencies analysis, the rs6898743 of GHR was associated with decreased susceptibility of EC (OR = 0.83, 95% CI: 0.70–1.00, p = 0.049), while rs2274223 of PLCE1 was associated with increased 0.25‐fold EC risk (OR = 1.25, 95% CI: 1.02–1.53, p = 0.037). The “GC” genotype of rs6898743 was associated with a 0.24‐fold decreased risk of EC under co‐dominant model (OR = 0.76, 95% CI: 0.58–0.99, p = 0.046), and the “GA” genotype of rs2274223 was associated with increased EC risk under co‐dominant model (OR = 1.36, 95% CI: 1.04–1.77, p = 0.023). Using GTEx database, rs2274223 was found to be significant associated with increased PLCE1 expression (p = 4.1 × 10−7) in esophagus muscularis. The UALCAN database demonstrated that the GHR gene was under‐expressed in esophageal cancer tissues (p = 0.017). Conclusion The gene GHR and PLCE1 polymorphisms are associated with EC in the general population and the results need to be verified in future.

Long noncoding RNA LINC01234 silencing exerts an anti-oncogenic effect in esophageal cancer cells through microRNA-193a-5p-mediated CCNE1 downregulation. Cell Oncol (Dordr) 2020; 43:377-394. [PMID: 32130660 DOI: 10.1007/s13402-019-00493-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/30/2019] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Long non-coding RNAs (lncRNAs) are transcribed pervasively in the genome and act to regulate chromatin remodeling and gene expression. Dysregulated lncRNA expression has been reported in many cancers, but the role of lncRNAs in esophageal cancer (EC) has so far remained poorly understood. In this study, we aimed to understand the effect of lncRNA LINC01234 on EC development through competitively binding to microRNA-193a-5p (miR-193a-5p). METHODS The Gene Expression Omnibus (GEO) database was used for microarray-based EC expression profiling. Gain- and loss-of-function analyses were carried out in human EC-derived Eca-109 and EC9706 cells. Expression analyses of miR-193a-5p, LINC01234, CCNE1, caspase-3, p21, Bax, cyclinD1 and Bcl-2 were performed using RT-qPCR and Western blotting. Cell proliferation, colony formation and apoptosis analyses were carried out using MTT, Hoechst 33258 and flow cytometry assays. A xenograft EC model in nude mice was used to evaluate in vivo tumor growth and CCNE1 expression. RESULTS Microarray-based analyses revealed that LINC01234 expression was increased in primary EC samples, whereas that of miR-193a-5p was decreased. We found that CCNE1 was a target of miR-193a-5p and that LINC01234, in turn, sponges miR-193a-5p. After treatment with si-LINC01234 or miR-193a-5p mimic, EC cells (Eca-109 and EC9706) exhibited cyclinD1 and Bcl-2 downregulation, and caspase-3, p21, Bax and cleaved caspase-3 upregulation. LINC01234 silencing or miR-193a-5p upregulation resulted in decreased proliferation and colony formation, and increased apoptosis of EC cells. In addition, LINC01234 silencing or miR-193a-5p upregulation resulted in reduced in vivo EC tumor growth and CCNE1 expression in nude mice. CONCLUSIONS We found that silencing of LINC01234 suppresses EC development by inhibiting CCNE1 through competitively binding to miR-193a-5p, which suggests that LINC01234 may represent a novel target for EC therapy.

Abstract
BACKGROUND Esophageal cancer is one of the most poorly diagnosed and fatal cancers in the world. Although a series of studies on esophageal cancer have been reported, the molecular pathogenesis of the disease remains elusive.
AIM To investigate comprehensively the molecular process of esophageal cancer.
METHODS Differential expression analysis was performed to identify differentially expressed genes (DEGs) in different stages of esophageal cancer from The Cancer Genome Atlas data. Exacting gene interaction modules were generated, and hub genes in the module interaction network were found. Further, through survival analysis, methylation analysis, pivot analysis, and enrichment analysis, some important molecules and related functions/pathways were identified to elucidate potential mechanisms in esophageal cancer.
RESULTS A total of 7457 DEGs and 14 gene interaction modules were identified. These module genes were significantly involved in the positive regulation of protein transport, gastric acid secretion, insulin-like growth factor receptor binding, and other biological processes as well as p53 signaling pathway, epidermal growth factor signaling pathway, and epidermal growth factor receptor signaling pathway. Transcription factors (including hypoxia inducible factor 1A) and non-coding RNAs (including colorectal differentially expressed and hsa-miR-330-3p) that significantly regulate dysfunction modules were identified. Survival analysis showed that G protein subunit gamma transducin 2 (GNGT2) was closely related to survival of esophageal cancer. DEGs with strong methylation regulation ability were identified, including SST and SH3GL2. Furthermore, the expression of GNGT2 was evaluated by quantitative real time polymerase chain reaction, and the results showed that GNGT2 expression was significantly upregulated in esophageal cancer patient samples and cell lines. Moreover, cell counting kit-8 assay revealed that GNGT2 could promote the proliferation of esophageal cancer cell lines.
CONCLUSION This study not only revealed the potential regulatory factors involved in the development of esophageal cancer but also deepens our understanding of its underlying mechanism.

Abstract
BACKGROUND Esophageal cancer (EC) is the sixth leading cause of cancer death worldwide, and the overall incidence is increasing. OBJECTIVE The aim of this study was to evaluate the association between single nucleotide polymorphisms in IL1R2 and EC risk in the Chinese population. METHODS Genotyping of six SNPs of IL1R2 was performed with the Agena MassARRAY platform from 384 EC and 499 controls. The association between polymorphisms and EC risk was assessed by performing genetics models and haplotype analyses. RESULTS Overall analysis results showed that the allele C of rs11674595 (odds ratio [OR] = 1.42, 95% confidence interval [CI]: 1.14-1.77, p = 0.002) and allele G of rs2072472 (allele: OR = 1.35, 95% CI: 1.08-1.69, p = 0.008) were associated with an increased EC risk. The rs11674595 and rs2072472 were found to be correlated with EC risk under the codominant, dominant, and additive models. Stratification analysis found that rs11674595 and rs2072472 were associated with increased EC risk in male and in age > 55 years old subgroup. In addition, Crs11674595Grs4851527 haplotype was significantly associated with 1.44-fold increased risk of EC (95% CI: 1.12-1.84, p = 0.004). CONCLUSION Our results reveal the significant association between SNPs (rs11674595 and rs2072472) in the IL1R2 and EC risk in the Chinese Han population. The findings may provide meaningful reference for the prevention and treatment of EC.

Genetic variations associated with telomere length confer risk of gastric cardia adenocarcinoma. Gastric Cancer 2019; 22:1089-1099.

Abstract
BACKGROUND Aberrant telomere lengthening is a critical feature of malignant cells. Short leukocyte telomere length (LTL) confers elevated risk of gastric cardia adenocarcinoma (GCA). Multiple genome-wide association studies (GWAS) identified various single-nucleotide polymorphisms (SNPs) associated with LTL in different ethnic populations. However, it remains largely unexplored how these genetic variants are involved in GCA susceptibility. METHODS We systematically screened GWAS-identified candidate SNPs and tested the impact of 30 polymorphisms in genes associated with interindividual LTL variation on GCA using two-stage case-control comparisons consisting of 1024 GCA patients and 1118 controls. RESULTS We observed that CXCR4 rs6430612, TERT rs10069690, and rs2853676 as well as VPS34 rs2162440 are significantly associated with GCA development. A 0.64-fold decreased risk of GCA is associated with the CXCR4 rs6430612 CT genotype compared with the CC genotype (P = 0.002). On the contrary, the TERT rs10069690 TT genotype carriers had a 1.83-fold increased risk to develop GCA compared to the CC genotype carriers (P = 5.8×10-6). We also detected a 2.17-fold increased OR for GCA that was associated with the TERT rs2853676 TT genotype (P = 2.6×10-6). In addition, the odds of having the VPS34 rs2162440 GA genotype in GCA patients were 1.35 compared with the GG genotype (P = 0.002). In stratified analyses, the association between TERT rs10069690 polymorphism and GCA was more pronounced in nonsmokers (Pinteraction = 9.7 × 10-5) and nondrinkers (Pinteraction = 4.6 × 10-5). CONCLUSIONS Our results highlight the importance of both LTL and LTL-related genetic variants to GCA predisposition.

[PMID: 31454181 PMCID: PMC6785442 DOI: 10.1002/mgg3.903] [Citation(s) in RCA: 5] [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: 12/11/2018] [Revised: 06/21/2019] [Accepted: 07/17/2019] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Studies have identified that the telomerase reverse transcriptase (TERT) gene polymorphism rs10069690 (C>T) is associated with cancer risk, but the results remain inconclusive. METHODS To provide a more precise estimation of the relationship, we performed a meta-analysis of 45 published studies including 329,035 cases and 730,940 controls. We conducted a search in PubMed, Google Scholar and Web of Science to select studies on the association between rs10069690 and cancer risk. Stratification by ethnicity, cancer type, cancers' classification, source of control, sample size, and genotype method was used to explore the source of heterogeneity. The pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were evaluated using random effects models. Sensitivity, publication bias, false-positive report probability (FPRP) and statistical power were also assessed. RESULTS The result demonstrated that rs10069690 was significantly associated with an increased risk of cancer overall (OR = 1.09, 95% CI: 1.06-1.12, p < .001) under the allele model. Stratification analysis revealed an increased cancer risk in subgroups of breast cancer, ovarian cancer, lung cancer, thyroid cancer, and renal cell carcinoma (RCC). However, a significantly decreased association was observed in pancreatic cancer in the European population (OR = 0.93,95% CI: 0.87-0.99, p = .031). In the subgroup analysis based on cancer type, no significant association was found in prostate cancer, leukemia, colorectal cancer and glioma. CONCLUSIONS This meta-analysis suggested that the TERT rs10069690 polymorphism may be a risk factor for cancer, especially breast cancer, ovarian cancer, lung cancer, thyroid cancer, and RCC. Further functional studies are warranted to reveal the role of the polymorphism in carcinogenesis.

Abstract
Esophageal cancer (EC) is a frequent malignant tumor in our world, and has a highly morbidity and mortality. It was reported that genetic factors play vital roles in its pathogenesis. Here, we performed a case - control study to evaluate the COL6A3 genetic variants and EC risk in a Chinese Han cohort. All subjects were genotyped with the Agena MassARRAY platform. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression after adjusting age and gender. We found that rs6720283 (G > A) allele had significantly enhanced EC risk (OR = 1.32, 95% CI = 1.11 alculate p = 0.002). Stratified analysis was performed by gender, age, alcohol drinking, BMI, TNM stage and lymph node metastasis, the results showed that rs7436, rs115510139 and rs6720283 were significantly associated with the risk of EC in different groups (all p < 0.05). Besides, no statistical significant was found between the COL6A3 gene polymorphisms and clinicopathological parameters such as TNM stage and lymph node metastasis among EC patients (p > 0.05). In conclusions, our study found that COL6A3 variants were associated with risk of EC in the Chinese population.

[PMID: 29507683 PMCID: PMC5823638 DOI: 10.18632/oncotarget.23905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2017] [Accepted: 12/26/2017] [Indexed: 11/25/2022] Open
Abstract
In this study, we investigated the association between the polymorphisms of telomerase reverse transcriptase (TERT) gene and the risk of chronic hepatitis B (CHB) in a Chinese Han population. Four single nucleotide polymorphisms (SNPs) in TERT (rs10069690, rs2242652, rs2853677 and rs2853676) were genotyped from 224 CHB patients and 300 healthy controls using the Sequenom Mass-ARRAY platform. We used genetic model, haplotype analyses, chi-square test, logistic regression analysis to evaluate the association between SNPs and CHB risk. The relative risk was estimated by odd ratios (ORs) and 95% confidence intervals (CIs). We found that rs10069690 was significantly associated with an increased CHB risk in the dominant model (adjusted OR = 1.70, 95% CI: 1.06–2.71, P = 0.031) and additive model (adjusted OR = 1.62, 95% CI: 1.09–2.41, P = 0.018). The haplotype “TA” (rs10069690 and rs2242652) was found to be associated with an increased risk of CHB (adjusted OR = 1.58, 95% CI: 1.05–2.38, P = 0.027). Our results suggested potential genetic contributes for TERT in CHB development in a Chinese Han population. Future functional and association studies with larger sample sizes are required to confirm these findings.

[PMID: 29299136 PMCID: PMC5746371 DOI: 10.18632/oncotarget.22329] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2017] [Accepted: 09/05/2017] [Indexed: 11/29/2022] Open
Abstract
The study was aimed to explore whether the TERT and TERC polymorphisms are associated with the lung cancer risk. Five TERC and TERT polymorphisms were genotyped from 554 lung cancer patients and 603 healthy controls. We used χ2 test, genetic model, linkage disequilibrium (LD) and haplotype analyses to evaluate the association between the polymorphisms and lung cancer risk. We found that the allele “C” of rs10936599 (TERC) and the allele “T” of rs10069690 (TERT) were associated with increased risk of lung cancer (OR = 1.32, 95% CI: 1.12-1.55, P = 0.001; OR = 1.41, 95% CI: 1.14-1.76, P = 0.002, respectively). The genotype of “CC” of rs10936599, genotype “CT” of rs10069690 and genotype “GG and “AG” of rs2853677 were also associated with increased the risk of lung cancer. In addition, rs10936599 under the dominant, recessive and log-additive models; rs10069690 under the dominant, overdominant and log-additive models; rs2853677 under the dominant and log-additive models were found to be associated with increased lung cancer risk. The SNP rs2242652 was found to be associated with an increased lung cancer risk under the dominant and overdominant models without adjustment. The haplotype “TA” of TERT was also associated with an increased risk of lung cancer. Our study indicated that rs10936599 (TERC) and rs10069690, rs2242652 and rs2853677 in TERT and haplotype “TA” of TERT were revealed as risk factors of lung cancer in a Chinese Han population. However, it required to verify our result and investigate the function genetic variants and mechanism of lung cancer.
