This study aims to scan the 5'-upstream regulatory region of the p21 gene to identify all putative functional single nucleotide polymorphisms (SNPs) and to evaluate the contribution of p21 variants to oesophageal squamous cell carcinoma (ESCC) in the Chinese Han population. Common SNPs were identified, and both locus-based and haplotype-based association tests were used to evaluate the potentia...

ISG15, the protein encoded by interferon (IFN)-stimulated gene 15, was the first identified ubiquitin-like protein, which could be strongly upregulated by type I interferons as a primary response to diverse microbial and cellular stress stimuli. Although the biological activities of ISG15 have yet to be fully elucidated, it is frequently overexpressed in various cancers. As the role of ISG15 in...

Previous studies have shown that the anomalous fruit extract of Gleditsia sinensis (GSE) exhibited apoptotic properties in various solid and non-solid tumors in vitro. However, the inhibitory actions of GSE on oncogenic expression and telomerase activity in esophageal squamous cell carcinoma (ESCC) have not been studied before. In the present study, the anti-cancer effects of GSE were demonstra...

Radiotherapy for esophageal squamous cell carcinoma (ESCC) patients is limited by resistance to ionizing radiation (IR). However, the roles and mechanisms of microRNAs in radioresistance are obscure. Here, we investigated that microRNA-205 (miR-205) was upregulated in radioresistant (RR) ESCC cells compared with the parental cells. Overexpression of miR-205 promoted colony survival post-IR, whe...

Myc is a ubiquitous mediator of cell proliferation that transactivates the expression of various genes through E-box sites. Here we report a novel gene, mimitin (Myc-induced mitochondrial protein), that encodes a mitochondrial protein with a molecular mass of 20 kDa. We demonstrated that the transcription of mimitin is directly stimulated by c-Myc. To investigate the role of Mimitin, its expres...

The pathogenesis of esophageal squamous cell carcinoma (ESCC) involves both genetic and environmental factors. Previously, we have carried out gene and protein expression profiling of ESCC using DNA microarrays and mass spectrometry-based quantitative proteomics, respectively. These studies resulted in identification of several potential biomarkers of ESCC, some with known reports of differenti...

BACKGROUND ErbB4 expression has been noted in various tumors, but its regulatory mechanism in esophageal squamous cell carcinoma (ESCC) remains unclear. The aim of this study was to investigate whether miR-302b regulates the expression of ErbB4 at the post-transcriptional level and to determine its expression, significance, and function in ESCC. METHODS We used real-time reverse transcriptase...

The dysregulation of the ubiquitously transcribed TPR gene on the X chromosome (UTX) has been reported to be involved in the oncogenesis of several types of cancers. However, the expression and significance of UTX in esophageal squamous cell carcinoma (ESCC) remains largely undetermined. Immunohistochemistry was performed in 106 ESCC patients, and correlated with clinicopathological features an...

This study investigated the correlation of preoperative plasma fibrinogen level with distant metastasis and prognosis in esophageal squamous cell carcinoma (ESCC). A total of 255 patients with ESCC who underwent surgery in Zhejiang cancer hospital (Hangzhou, China), between October 2006 and December 2009, were evaluated in this retrospective study. Population controls were selected from a pool ...

In this study, we investigated the association between the FasL -844T/C polymorphism and the risk of developing esophageal squamous cell carcinoma (ESCC) in South China. For the investigation, we randomly selected 248 patients suffering from ESCC from Southern China along with 297 healthy individuals as the control group. The relationship between the FasL gene -844T/C SNP and ESCC was studied u...
