MicroRNAs have emerged as important gene regulators and are recognised as key players in carcinogenesis. In the present study, we show that miR-126 was significantly down-regulated in gastric cancer tissues compared with matched normal tissues and was associated with clinicopathological features, including tumour size, lymph node metastasis, local invasion(More)
BACKGROUND Insufflation with standard cold-dry CO(2) during laparoscopic surgery has been shown to predispose patients to hypothermia and peritoneal injury. This study aimed to compare the effect of prolonged cold-dry CO(2) insufflation with heated-humidified CO(2) insufflation (3-5 h) on hypothermia, peritoneal damage, and intra-abdominal adhesion(More)
A major hallmark of pancreatic ductal adenocarcinoma (PDAC) is extensive local tumor invasion and early systemic dissemination. DJ-1 has been shown to prevent cell death via the Akt pathway, thereby playing an important role in cancer progression and Parkinson's disease development. Here, we investigated the role of DJ-1 in tumor invasion and metastasis of(More)
Iron deficiency anemia is an extra-stomach disease experienced in H. pylori carriers. Individuals with type A blood are more prone to suffering from H. pylori infection than other individuals. To clarify the molecular mechanisms underlying H. pylori-associated anemia, we collected erythrocytes from A, B, O, and AB blood donors and analyzed morphology, the(More)
The performance of the communication network can greatly affect the ability of scientific applications to make efficient use of the computational power available in high-performance computing systems. Many tools exist for analyzing network performance, but most concentrate on a single layer in the communication subsystem or on one type of network hardware.(More)
OBJECTIVES To demonstrate the diagnostic significance of methylation, an important molecular event in gastric carcinogenesis. DESIGN AND METHODS We used methylation microarray to determine candidate genes, and performed MSP to evaluate the methylation status of them in tissues and sera. The effect of demethylation on mRNA expression was investigated by(More)
Deregulation of E2F1 activity is characteristic of gastric tumorigenesis, which involves in complex molecular mechanisms. microRNA is one of the post-transcriptional regulators for gene expression. Here, we report a member of miR-331 family, miR-331-3p, which was decreased in some kinds of malignancies. However, the biological function of miR-331-3p on(More)
Cancer-associated fibroblasts (CAFs), as the activated fibroblasts in tumor stroma, are important modifiers of tumor progression. However, the mechanisms underlying stromal fibroblast activation and their promotion of tumor growth remain largely unknown in gastric cancer. Here, we show that normal fibroblasts (NFs) from non-cancerous regions of gastric(More)
To define the early cytogenetic events important in esophageal carcinogenesis, we immortalized normal esophageal epithelial cells by overexpression of human papillomavirus type 16 E6/E7 (HPV16E6/E7) and human telomerase reverse transcriptase (hTERT), and characterized the chromosomal abnormalities serially before and after cellular immortalizaiton.
