abstract introduction: peptic ulcer is a common problem in medicine with serious impacts on the quality of life of patients. it has been shown that helicobacter pylori infection is related with inflammatory responses of gastric mucosa. however, some patients remain asymptomatic. sustained colonization and chronic inflammation increase the risk of gastritis and peptic ulcer. the aim of this stud...

BACKGROUND Chronic inflammation plays a causal role in gastric tumor initiation. The identification of predictive biomarkers from gastric inflammation to tumorigenesis will help us to distinguish gastric cancer from atrophic gastritis and establish the diagnosis of early-stage gastric cancer. Phospholipase C epsilon 1 (PLCε1) is reported to play a vital role in inflammation and tumorigenesis. T...

Background: Gastric cancer arises, mainly, on an inflammatory background. Helicobacter pylori neutrophil activating (HP-NAP) protein functions as a potent pro-inflammatory mediator.  Similarly, IL-4 plays a critical role in the inflammation pathway, the levels of which are altered by C to T transition at position -590 in its promoter region. Here, we have aimed to assess the risk of gastri...

Genetic susceptibility seems to play an important role in some gastric cancers. In some rare cases, gastric cancer can be one part of familial cancer syndromes. A well-known example is the family of Napoleon since the Emperor himself as well as his father and his grandfather had gastric cancer. Generally, hereditary factors include germline mutations of E-cadherin, APC, p53 or mismatch repair g...

Gastric cancer is the second most common cause of cancer-related death in the world. A growing body of evidence indicates that inflammation is closely associated with the initiation, progression, and metastasis of many tumors, including those of gastric cancer. In addition, approximately 60% of the world's population is colonized by Helicobacter pylori, which accounts for more than 50% of gastr...

Gastric trefoil peptides mediate mucosal repair by stimulating cell migration, inhibiting apoptosis and inflammation, and likely augmenting the barrier function of mucus. One of these, tff1, is a gastric-specific tumor suppressor gene, which when repressed is associated with gastric cancer progression. IL-6 family cytokines play an important role in maintaining gastric homeostasis by regulating...

Signal Transducer and Activator of Transcription-3 (STAT3) is constitutively activated in many cancers where it promotes growth, inflammation, angiogenesis and inhibits apoptosis. We have shown that STAT3 is constitutively activated in human gastric cancer, and that chronic IL-11-driven STAT3 transcriptional activity induces gastric tumourigenesis in the gp130(757FF) mouse model of gastric canc...

Revelation of the connection between Helicobacter pylori infection and gastric adenocarcinoma has prompted new investigations pertaining to its basic and clinical aspects. H. pylori-induced persistent and uncontrolled gastric inflammation nearly always precedes the development of cancer and is instrumental in initiating a multistep process leading to carcinogenesis. Despite initial optimism abo...
