Telomerase activation is one of the main pathways to immortalize cancer cells. In many kinds of cancer cells, this special reverse transcriptase stabilizes and elongates telomeres and prevents telomere erosion that naturally occurs in every cell division. Esophageal cancer is the fifth most frequent cause of cancer death worldwide, and is highly associated with alcohol, smoking, cultural habits...

Symptomatic skeletal muscle metastasis from esophageal adenocarcinoma is rare. Here we report the case of a 49-year-old man who presented with right thigh pain, and was found to have symptomatic psoas muscle metastasis as the presentation of esophageal adenocarcinoma. The primary tumor was notable for signet ring cells (SRC), a poor prognostic indicator as well as a predictor of biologic aggres...

Radiotherapy is widely used for treatment of esophageal squamous cell carcinoma (ESCC). This study aimed to explore the role of Derlin-1 on the sensitivity of ESCC to radiotherapy and its underlying mechanism. We examined the clinical significance of Derlin-1 in 125 ESCC tissues. We found that Derlin-1 protein was higher in ESCC tissues than that in normal esophageal epithelial tissues. Derlin-...

According to the 2018 global cancer statistics, China accounts for more than 50% of new cases and mortality esophageal worldwide. Esophageal squamous carcinoma (ESCC) is predominant subtype in China, early diagnosis ESCC important because its poor prognosis high rate. Metabolomics has become an approach exploring biomarkers advantages easy sampling, dynamic real-time detection low bias results....

BACKGROUND Esophageal cancer has a high mortality rate, particularly in Asia, and there are obvious racial differences in regard to incidence. The purpose of our study was to assess the genetic susceptibility of functional single nucleotide polymorphisms in flap endonuclease-1 (FEN1) in esophageal squamous cell carcinoma ESCC. METHODS Clinical blood samples of 629 ESCC cases and 686 control s...

BACKGROUND/AIM The expression of Wingless/int-1 (Wnt)-induced secreted protein-1 (WISP-1/CCN4), a member of the Cyr61-CTGF-Nov (CCN) family, has been examined in several types of cancer. However, the correlation between the WISP-1 expression and the clinical features of esophageal squamous cell carcinoma (ESCC) remain to be elucidated. This study aimed to clarify the expression of WISP-1 protei...

There is no doubt that, along with surgery, chemoradiotherapy is an important treatment for esophageal squamous cell carcinoma (ESCC). Patients who respond well to chemoradiotherapy obtain great benefits toward overcoming their cancer, and so a more favorable prognosis. On the other hand, patients who do not respond well have wasted valuable time and experienced severe toxicity and seriously di...

Esophageal squamous cell carcinoma (ESCC) is associated with the accumulation of genetic and epigenetic changes in the background mucosa. Dysregulated DNA methylation is known to lead to the inactivation of tumor suppressor genes and the activation of oncogenes. To identify the genes whose expression is perturbed by abnormal DNA methylation in ESCC, integrative transcriptomics by serial analysi...

PURPOSE This study aims to identify differentially expressed genes in esophageal squamous cell carcinoma (ESCC) through the use of a membrane-based cDNA array. EXPERIMENTAL DESIGN Two newly established human ESCC cell lines (HKESC-1 and HKESC-2) and one corresponding to a morphologically normal, esophageal epithelium tissue specimen, prospectively collected from the HKESC-2-related patient, w...

Bufadienolides are a type of cardiotonic steroids isolated from the skin and parotid venom glands of the toad Bufo bufo gargarizans Cantor, and exhibit wide-spectrum anticancer activities. However, the effects and mechanisms of bufadienolides on esophageal squamous cell carcinoma (ESCC) cells remain unknown. In the present study, the anticancer activities of two bufadienolides, bufotalin and bu...
