Gastric cancer; Gene polymorphism; Interleukin-10; Meta-analysis

Numerous studies have evaluated the association between the human interleukin-10 gene -592C>A polymorphism and gastric cancer risk. However, the results have been inconsistent. This meta-analysis was designed to resolve these controversies. Systematic searches of the electronic databases Embase, PubMed, and Google Scholar were performed to identify relevant studies. A meta-analysis was ... more

Differential expression; Gastric cancer; MicroRNAs; Network analysis

To identify potential targets for the early treatment and prevention of gastric cancer, microRNA (miRNA) expression profiles of precancerous lesions of gastric cancer were investigated. The miRNA microarray dataset GSE24839 was downloaded from Gene Expression Omnibus (GEO) and included 10 Helicobacter pylori-related gastritis samples and 10 gastric intestinal metaplasia samples. ... more

Aberrant DNA methylation; Gastric cancer; hMLH1; MGMT

We aimed to explore the association between aberrant DNA methylation of the O(6)-methylguanine-DNA methyltransferase (MGMT) and human mutL homolog 1 (hMLH1) genes with gastric cancer. A total of 283 gastric cancer patients who were confirmed by pathological diagnosis were included in our study. Aberrant DNA methylation of MGMT and hMLH1 were detected. The proportions of ... more

Gastric cancer; Haplotype analysis; Methylenetetrahydrofolate reductase; susceptibility

Epidemiological studies have indicated that folate metabolism is correlated with increased risk of gastric cancer. Since methylenetetrahydrofolate reductase (MTHFR) is an important enzyme involved in folate metabolism, in this study, we examined whether polymorphisms and haplotypes of MTHFR are correlated with the risk of gastric cancer. The polymorphisms MTHFR C677T and ... more

Chemotherapy; Gastric cancer; Meta-analysis; Polymorphism; XRCC1

It is still controversial whether X-ray repair cross-complementing group (XRCC1) gene polymorphisms (Arg194Trp and Arg399Gln) are associated with the clinical outcome of platinum-based chemotherapy in gastric cancer patients based on published studies. Meta-analysis was performed to provide a systematic review of the findings. Eligible articles from the PubMed, SinoMed, and CNKI ... more

Gastric cancer; IL-17A; IL-17F; Polymorphism

We conducted a meta-analysis of eligible studies to estimate the association between gastric cancer risk and rs2275913G>A IL-17A and rs763780T>C IL-17F polymorphisms. We searched the relevant studies in both Chinese and English through PubMed, the Web of Science, the Cochrane Library, and EMBASE up to January 1, 2014, including 3939 cases and 5407 controls. Seven eligible case- ... more

EGFR; ERBB1; Gastric cancer; Polymorphism

Epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein with tyrosine-kinase activity that plays an important role in multiple cellular functions. EGFR overexpression has been observed in several types of tumors and it is significantly associated with disease stage, survival, prognosis, and progression of cancer. The polymorphisms -216G>T, -191C>A, and (CA)n ... more

C-erbB-2; Gastric cancer; Meta-analysis; Prognosis

The prognostic role of c-erbB-2 in gastric cancer is controversial. We conducted a meta-analysis to evaluate the relationship between c-erbB-2 expression and the prognosis of gastric cancer. We evaluated 20 published studies assessing the relationship between c-erbB-2 and gastric cancer prognosis. The Revman 5.0 software was used to perform literature retrieval, article selection, data ... more

Clinicopathological characteristics; Gastric cancer; Hypoxia-inducible factor-2α; Prognosis

Hypoxia influences tumor growth by inducing angiogenesis and genetic alterations. Hypoxia-inducible factor-2α (HIF-2α) plays an essential role in oxygen homeostasis. Expression of HIF-2α-inducible genes is associated with tumor progression. In this study, we investigated this correlation immunohistochemically and using quantitative reverse transcription-polymerase chain reaction to ... more
