Cancer-associated fibroblasts (CAFs) play important roles in cancer progression. Twist1 was recently reported to be a key regulator of CAFs in gastric cancer, but its role in other types of cancer remains unclear, especially for esophageal squamous cell carcinoma (ESCC). We assessed the Twist1 expression on stromal fibroblasts using immunohistochemistry in 169 tissue specimens from ESCC patient...

Patients with esophageal squamous cell carcinoma (ESCC) are often diagnosed with advanced diseases that respond poorly to chemotherapy. Here we reported that Apollon, a membrane-associated inhibitor of apoptosis protein, was overexpressed in ESCC cell lines and clinical ESCC tissues, and Apollon overexpression clinically correlated with poor response to chemotherapy (P = 0.001), and short overa...

Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive cancers in China, but the underlying molecular mechanism of ESCC is still unclear. Involvement of microRNAs has been demonstrated in cancer initiation and progression. Despite the reported function of miR-503 in several human cancers, its detailed anti-oncogenic role and clinical significance in ESCC remain undefined. In th...

The development of esophageal squamous cell carcinoma (ESCC) has been linked to exposure to carcinogens such as nitrosamines that cause various alkyl DNA damages and O6-methylguanine-DNA methyltransferase (MGMT) is a primary defence against alkylation-induced mutagenesis and carcinogenesis. This study was to investigate the role of inactivation of MGMT by promoter hypermethylation and its relat...

BACKGROUND Esophageal squamous cell carcinoma (ESCC) is a highly aggressive cancer whose underlying molecular mechanisms are poorly understood. The natural antisense transcript (NAT) WRAP53 regulates p53 expression and WRAP53 protein is a component of telomerase. NATs play key roles in carcinogenesis, and although WRAP53 is known to increase cancer cell survival, its role in ESCC clinicopatholo...

The differential expression of microRNAs (miRNAs) in plasma of esophageal squamous cell carcinoma (ESCC) patients may serve as a diagnostic biomarker. A four-stage study was conducted to identify plasma miRNAs with potential in detecting ESCC. Exiqon panels (2 ESCC pools vs. 1 normal control (NC) pool) were applied in the screening phase to obtain miRNA profiles. The identified miRNAs were furt...

Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive malignancies. Recently developed molecular targeted therapies are not available for patients with ESCC. After curative surgical resection, patients frequently suffer distant metastasis and recurrence. Exploration of novel ESCC metastatic pathways may lead to the development of new treatment protocols for this disease. Accor...

Aberrant overexpression of autocrine motility factor and its receptor (AMFR) is observed in many cancers but not in esophageal squamous cell cancer (ESCC). In this study, upregulated rho-associated protein kinase 2, p-cofilin and intracellular adhesion molecule-1, and downregulated E-cadherin were found in ESCC cells transfected with the plasmid pcDNA 3.1-AMFR-C, while opposite results were obs...

AIM Previous studies have shown that neutrophil gelatinase-associated lipocalin (NGAL) is overexpressed in oesophageal squamous cell carcinoma (ESCC) and closely associated with the invasiveness of ESCC cells. Recently, NGAL receptor (NGALR) was identified from ESCC cells, and was also found to be increased in ESCC. The purpose of this study was to reveal the clinical significance of NGAL and/o...

Esophageal squamous cell carcinomas (ESCC) have become a severe threat to health and the current treatments for ESCC are frequently not effective. Recent epidemiological studies suggest that the anti-hyperglycemic agent metformin may reduce the risk of developing cancer, including ESCC, among diabetic patients. However, the antitumor effects of metformin on ESCC and the mechanisms underlying it...
