BACKGROUND The prognosis of H. pylori infection-negative gastric cancer (HPIN-GC) has been rarely investigated. Applying a strict definition of H. pylori status, the prognosis and molecular prognostic markers in HPIN-GC were evaluated. METHODS A combination of multiple methods was carried out to strictly evaluate H. pylori infection in gastric cancer (GC) patients between June 2003 and Octobe...

Histone deacetylase 8 (HDAC8), a unique member of class I HDACs, shows remarkable correlation with advanced disease stage. The depletion of HDAC8 leads to inhibition of proliferation, apoptosis and cell cycle arrest in multiple malignant tumors. However, little is known about the contribution of HDAC8 to the tumorigenesis of gastric cancer (GC). The present study investigated expression of HDAC...

background: chronic inflammation and dys-regulation of the immune system mechanisms are now well established as primary triggers of gastric cancer and peptic ulcer disease. galectin-9 (gal-9) is a member of the galectin family and known as an inducer of cell aggregation, adhesion and apoptosis. gal-9 interaction with its main ligand t-cell immunoglobulin and mucin domain protein-3 (tim-3) leads...

Gastric cancer (GC) is highly prevalent in Asia and the third most common cause of cancer death after lung cancer and liver cancer in Korea (Jung et al., 2012). The 5-year survival rate for gastric cancer is over 60%, however, the late onset of clinical symptoms occurred late diagnose at an advanced stage, which limits available therapeutic approaches in more than 50% of cases (Strong et al., 2...

Background: T-cell immunoglobulin and mucin domain protein-3 (Tim-3), an inhibitory immunoregulatory receptor, has been recently implicated in tumor biology and tumor-associated immune suppression. In the present study, expression of Tim-3 was evaluated in gastric cancer (GC) and peptic ulcer disease (PUD) at both mRNA and protein levels. Methods: A total of 133 gastric tissue biopsies, compris...

To systematically and quantitatively review the relation of abdominal obesity, as measured by waist circumference (WC) and waist to hip ratio (WHR), to total gastroesophageal cancer, gastric cancer (GC), and esophageal cancer. PubMed and Web of Science databases were searched for studies assessing the association between abdominal obesity and gastroesophageal cancer (GC and/or esophageal cancer...

Abnormal interactions between cytokines may be an overlooked mechanism linking the development of different types of gastric neoplasms. In this study a comprehensive analysis of the systemic levels of interleukins (IL-1,IL-6, IL-8,IL-10 and IL-12) was performed in 75 patients with different gastric neoplasms (cancer, gastrointestinal stromal tumors, neuroendocrine neoplasms, lymphomas) and 40 h...

Long non-coding RNAs (lncRNAs) are crucial in contributing to gastric tumorigenesis and development. However, the diagnostic value of the majority of lncRNAs in gastric cancer (GC) are not clear. The present study investigated the diagnostic value of gastric cancer associated transcript 2 (GACAT2), a lncRNA that is aberrantly expressed in GC tissues. A total of 343 plasma samples from 80 health...

Dysregulation of microRNA (miRNA) is actively involved in the development and progression of gastric cancer (GC). MiR-520c was previously found to be overexpressed in GC specimens and cells. However, the clinical significance of miR-520c and its biological function in GC remain largely unknown. Here, we found that miR-520c expression in GC tissues was significantly increased compared to normal ...
