Esophageal cancer (EC) is the ninth most common malignancy with a poor prognosis. It is clear that improvements need to be made to reveal the exact molecular mechanisms of EC. Cancer-related inflammation (CRI) recently has been proposed as a major physiological hallmark of malignancy and has important value in diagnosis, treatment, and prognosis. But the(More)
Apoptin, a 13.6-kD protein encoded by chicken anemia virus, is paid more and more attention, since it selectively induces apoptosis in tumor cells while abolishes cytotoxic effect in normal cells. In addition, Apoptin shows different localization in tumor cells and normal cells: it predominantly accumulates in nucleus of tumor cells, whereas in normal(More)
MicroRNAs (miRNAs) represent a class of small non-coding RNAs that regulate gene expression at the post-transcriptional levels. Recent studies show that miRNAs may function as oncogenes or tumor suppressor genes. In this study, we demonstrated that miR-518b was down-regulated in esophageal squamous cell carcinoma (ESCC) tissues and correlated with(More)
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(More)
BACKGROUND Propofol is one of the most commonly used intravenous anaesthetic agents during cancer resection surgery, but the effect of propofol on gallbladder cancer is not clear. NF-E2-related factor 2 (Nrf2) is abundantly expressed in cancer cells and relates to proliferation, invasion, and chemoresistance. The aims of the current study were to evaluate(More)
BACKGROUND Gallbladder cancer (GC) is considered a relatively rare malignancy with extensively poor prognosis. To guide clinicians in selecting treatment options for GC patients, reliable markers predictive of poor clinical outcome are desirable. This study analyzed the correlation of NF-E2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and multidrug(More)
BACKGROUND X-chromosome-linked IAP (XIAP) and nuclear factor-κB (NF-κB) are frequently overexpressed and correlate closely with chemoradiotherapy resistance and poor prognosis in many cancers. However, the significance of XIAP and NF-κB expression in radiotherapy sensitivity and its effect on the prognosis of esophageal squamous cell carcinoma (ESCC) are(More)
Radiation therapy can effectively kill cancer cells through ROS generation. Cancer cells with upregulated antioxidant systems can develop high radioresistance ability, and the transcription factor NF-E2-related factor 2 (Nrf2) is a key regulator of the antioxidant system. Currently, there are numerous data indicating the important role of Nrf2 in cancer(More)
Nrf2 is used as a cell protector by mediating many downstream genes which express phase II detoxifying and antioxidant enzymes. Recently, large numbers of experiments have shown Nrf2 and its downstream genes are found to be overexpressed in many human tumors. Numerous evidences unveil that Nrf2 protects the normal cells while promoting the malignant tumor's(More)
BACKGROUND Radiation resistance poses a major clinical challenge in treatment of esophageal squamous cell carcinoma (ESCC). However, the mechanisms of radioresistance has not been fully elucidated. Since accumulating evidence demonstrates that aberrant expression of microRNAs (miRNAs) contributes to cancer sensitivity to radiation, we aimed to identify(More)
