MicroRNAs play key roles in tumor metastasis. Here, we describe the regulation and function of miR-218 in gastric cancer (GC) metastasis. miR-218 expression is decreased along with the expression of one of its host genes, Slit3 in metastatic GC. However, Robo1, one of several Slit receptors, is negatively regulated by miR-218, thus establishing a negative(More)
OBJECTIVE We aimed first to investigate the expression pattern of miRNAs in esophageal squamous cell cancer and then compared it with those of adjacent benign esophageal tissues. The role of target miRNAs in the development of esophageal cancer was further detected. SUMMARY BACKGROUND DATA Although esophageal squamous cell carcinoma was of high incidence(More)
PURPOSE Notch1 has been proven to be aberrantly expressed in colorectal cancer and related to tumor differentiation status. However, few previous studies concentrated on the predictive role of Notch1 expression on the overall survival of patients with colorectal cancer. This study explored expression of Notch1 and its relationship with p65 and prognosis in(More)
MicroRNAs are small non-coding RNA molecules that control expression of target genes. Previous studies showed that microRNA-107 (miR-107) is overexpressed in gastric cancer tissues compared with the matched normal tissues. However, it remains largely unclear as to how miR-107 exerts its function and modulates the malignant phenotypes of gastric cancer,(More)
OBJECTIVE The prognostic role of tumor biological markers (biomarkers) in predicting recurrence of hepatocellular carcinoma (HCC) was investigated in this study, the results of which may help to select appropriate candidates for liver transplantation (LT). METHODS Tissue samples from 82 HCC patients with cirrhosis who had undergone LT were(More)
Multidrug resistance (MDR) is the most common cause of chemotherapy failure in gastric cancer (GC) treatment; however, the underlying molecular mechanisms remain elusive. Long noncoding RNAs (lncRNAs) can be involved in carcinogenesis, but the effects of lncRNAs on MDR are poorly understood. We show here that the lncRNA MRUL (MDR-related and upregulated(More)
Adenosine-to-inosine (A-to-I) RNA editing is a post-transcriptional modification of pre-mRNA catalysed by an RNA-specific adenosine deaminase (ADAR). A-to-I RNA editing has been previously reported in the pre-mRNAs of brain glutamate and serotonin receptors and in lung tissue during inflammation. Here we report that systemic inflammation markedly induces(More)
BACKGROUND Matrix metalloproteinase-9 is a member of the MMP family, which is overexpressed in some solid tumors and is thought to enhance tumor invasion and metastasis ability. The present study aims to examine MMP-9 expression in human colorectal cancer and to determine its association with clinicopathological characteristics and prognosis. METHODS(More)
Adenosine-to-inosine (A-to-I) RNA editing is a post-transcriptional process that amplifies the repertoire of protein production. Recently, the induction of this process through up-regulation of the editing enzyme RNA-specific adenosine deaminase 1 (ADAR1) was documented during acute inflammation. Here we report that the inflammation-induced up-regulation of(More)
OBJECTIVE This study aimed to compare the quality of life in Siewert type II esophagogastric junctional adenocarcinoma patients receiving either laparoscopic total gastrectomy or open total gastrectomy. METHODS From Sep 1, 2008 to May 1, 2012, totally 204 consecutive patients with Siewert type II esophagogastric junctional adenocarcinoma were involved in(More)
