Abstract Oxidative stress (OS) is intimately associated with tumorigenesis and has been considered a potential therapeutic strategy. However, the OS-associated therapeutic target for esophageal squamous cell carcinoma (ESCC) remains unconfirmed. In our study, gene expression data of ESCC and clinical information from public databases were downloaded. Through LASSO-Cox regression analysis, a risk score (RS) signature map of prognosis was constructed and performed external verification with the GSE53625 cohort. The ESTIMATE, xCell, CIBERSORT, TIMER, and ImmuCellAI algorithms were employed to analyze infiltrating immune cells and generate an immune microenvironment (IM). Afterward, functional enrichment analysis clarified the underlying… More >

Abstract The aim of this study was to examine the prognostic factors and treatment outcomes of cervical esophageal carcinoma (CEC) patients who underwent definitive chemoradiotherapy (CRT). The clinical data of 175 biopsy-confirmed CEC patients treated with definitive CRT between April 2005 and September 2021 were retrospectively analyzed. The prognostic factors predicting overall survival (OS), progression-free survival (PFS), and local recurrence-free survival (LRFS) were assessed in uni- and multivariable analyses. The median age of the entire cohort was 56 years (range: 26–87 years). All patients received definitive radiotherapy with a median total dose of 60 Gy, and… More >

Abstract Esophageal cancer is the second most common type of cancer after lung carcinoma in the state of Jammu and Kashmir (J&K). The understanding of genetics in Esophageal cancer development is poor in the state. Genome wide association studies (GWAS) has proved to be unsurpassed tool in identification of new loci associated with different cancers. GWAS in Chinese population has identified SNP rs2294693 present in UNC5CL (UNC-5 Family C-Terminal like) to be associated with non-cardia gastric cancer. We performed a case control association study and genotyped the SNP rs2294693 using Taqman allele discrimination assay in 566 individuals… More >

Abstract Esophageal cancer is a common gastrointestinal cancer, with a very high mortality rate in patients with metastasis. Swainsonine, a cytotoxic fungal alkaloid, has been shown to inhibit cell growth in esophageal cancer. In the present study, we explored the effects of swainsonine on cell invasion and metastasis in esophageal cancer cells. Human esophageal carcinoma cells were treated with different doses of swainsonine, and then cell viability, invasion, and apoptosis were measured. The mRNA and protein expressions of Twist1, apoptosis- and EMT-related factors, and PI3K/AKT pathway factors were detected by qRT-PCR and Western blot. Swainsonine had More >

Abstract Esophageal cancer is one of the most common types of cancer, and it has a poor prognosis. The molecular mechanisms of esophageal cancer progression remain largely unknown. In this study, we aimed to investigate the clinical significance and biological function of tumor necrosis factor receptor-associated factor 6 (TRAF6) in esophageal cancer. Expression of TRAF6 in esophageal cancer was examined, and its correlation with clinicopathological factors and patient prognosis was analyzed. A series of functional and mechanism assays were performed to further investigate the function and underlying mechanisms in esophageal cancer. Expression of TRAF6 was highly… More >

Abstract 2-Methoxyestradiol-bis-sulphamate is a bis-sulphamoylated derivative of the naturally occurring 17-beta-estradiol metabolite namely 2-methoxyestradiol. 2-Methoxyestradiol-bis-sulphamate is regarded as a potential anticancer drug with increased antiproliferative activity when compared to 2-methoxyestradiol. The aim of this pilot in vitro study was to determine the influence of 2-methoxyestradiol-bis-sulphamate on cell growth, morphology and possible induction of certain types of cell death in the SNO esophageal carcinoma cell line. A dose-dependent study (0.2-1.0μM) was conducted with an exposure time of 24 hours. Data revealed that 2-methoxyestradiol-bis-sulphamate reduced cell numbers statistically significantly to 74% after exposure to 0.4μM of the drug. Morphological More >
