Gastric cancer (GC) is a significant global health problem, with Helicobacter pylori infection estimated to be responsible for 89% of non-cardiac GC cases, or 78% all cases. The International Agency Research on Cancer has called test-and-treat strategies in countries high rates GC. However, low GC, such as most Western countries, the balance between benefits, harms and costs screening less clea...

Abstract Epstein-Barr virus-positive gastric cancer [EBV (+) GC] is a distinct GC subtype with unique genetic and epigenetic aberrations. Here, we examined resected samples publicly available microarray data The Cancer Genome Atlas (TCGA) database to identify the mechanism underlying overexpression of PD-L1 in EBV GC. We found that high levels were caused by focal amplification CD274 . By contr...

Gastric cancer (GC) is a major cause of cancer mortality. GC studies that aim to identify relevant oncogenes and tumor suppressor genes (TSGs) are essential for devising effective new therapies. A decade ago, RUNX3, a gene that resides on human chromosome 1p36.1, was claimed to be a major TSG in GC. Since then, hundreds of studies involving thousands of GC patients have attempted to verify and ...

Introduction: The global incidence of gastric cancer (GC) has been decreased dramatically in recent decades and characteristics of this cancer has been changed. Most of these changes can be resulted from changes in dietary and nutritional habits. This cancer is the most common cancer in north and northeast of Iran. In present report we will briefly summaries the gastric tumor location in a popu...

MicroRNAs are a group of small non-coding RNAs that modulate gene expression. The de-regulation of microRNA expression has been found in several types of cancer. To study the role of microRNAs in gastric cancer (GC), we analyzed the expression profile of 847 microRNAs in GC from Chinese patients. Total RNA was used for hybridization on the miRCURY LNA Array (v. 11.0), which contains probes spec...

Gastric cancer (GC) is one of the leading types of cancer worldwide, particularly in East Asian populations. Helicobacter pylori (HP) infection has been established as a major risk factor for GC. Although more than 50% of the world population is infected with this bacterium, less than 2% develop GC. Therefore, further risk factors (such as host genetic polymorphisms and lifestyle, as well as en...

This study aims to investigate the prognostic power of carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) in gastric cancer (GC) and its potential role in cancer development and progression. Data mining results show that CEACAM6 is overexpressed in gastric cancer and is correlated with lymph node metastasis. Subsequently, immunohistochemical staining was performed to determine ...

AIM This study aimed to determine the association between PD-1.5C/T (rs2227981, +7785) and the risk of gastric cancer (GC) in an Iranian population. BACKGROUND Gastric cancer is the fourth most common cancer in the world. The programmed death 1 (PD-1) is a member of the CD28 super family. PD-1 is a negative regulator of T-cell effector mechanisms which decrease immune responses against cancer...

Gastric cancer (GC) is one of the most common malignancies worldwide. In particular, scirrhous type GC is highly metastatic and is characterized clinically by rapid disease progression and poor prognosis. MicroRNAs (miRNAs) play crucial roles in cancer development and progression. In the present study, we identified several miRNAs that are expressed at higher levels in scirrhous type GC than in...
