Angiotensinogen; Gene polymorphism; Meta-analysis; Myocardial infarction

Numerous studies have evaluated the association between the T174M polymorphism in the angiotensinogen (AGT) gene and myocardial infarction (MI) risk. However, the specific association remains controversial because of small sample sizes and varied study designs among different studies. We performed a meta-analysis to assess this correlation. A comprehensive search was conducted to ... more

Estrogen receptor alpha; Fracture; Gene polymorphism; Meta-analysis

Numerous studies have evaluated the association between estrogen receptor alpha (ESR1) gene PvuII polymorphism and fracture risk in postmenopausal women. However, the results have been inconsistent. We performed a meta-analysis to examine the association between the ESR1 gene PvuII polymorphism and fracture risk in postmenopausal women. Studies ... more

CYP1A1; Gene polymorphism; Hepatocellular carcinoma; Meta-analysis

Numerous studies have evaluated the association between CYP1A1 gene polymorphisms and hepatocellular carcinoma (HCC) risk. However, the specific association is still controversial. The aim of our study was to clarify the effects of CYP1A1 gene polymorphisms (3801 T>C and A2455G) on HCC risk by conducting a meta-analysis. We conducted searches of the literature published in PubMed and ... more

Gene polymorphism; Interleukin-6; Lung cancer; Meta-analysis

The results of previous case-control studies examining the relationship between the interleukin (IL)-6 gene -174G>C polymorphism and lung cancer are controversial. In this study, we evaluated the relationship between the IL-6 gene -174G>C polymorphism and lung cancer. We selected 5 case-control studies related to the IL-6 gene -174G>C polymorphism and lung cancer by searching the ... more

Anti-proliferation; Gastric cancer; miRNA-199a-3p; mTOR

MicroRNAs (miRNAs) are small non-coding RNAs that regulate the translation of targeted mRNAs. An increasing amount of evidence indicates that miRNAs play important role in cancer pathogenesis, apoptosis, proliferation, and differentiation as oncogenes or tumor suppressors. Recently, miRNA-199a has been shown to be involved in many human cancers, although the role of miRNA-199a-3p in ... more

Amazon; Epstein-Barr; Gastric cancer; Polymerase chain reaction; Resection margin

Gastric cancer is one of most frequent causes of death in Brazil. The city of Manaus has one of the highest incidences of this disease in Brazil. The Epstein-Barr virus (EBV) is a ubiquitous herpesvirus that is classified as a group 1 carcinogen by the International Agency for Research on Cancer. We obtained biopsies from 6 control subjects and 10 patients with gastric carcinomas living ... more

DNA methylation; Gastric cancer; LOH; MSI; PAI-1 gene

We explored a possible correlation of genetic instability and CpG methylation in the 5'-flanking region of the PAI-1 gene with clinicopathologic features of gastric cancer in Chinese patients and looked for molecular markers for diagnosing gastric tumor development. Microsatellite instability and loss of heterozygosity of the PAI-1 gene locus D7S515, D7S471 and pai-1 ... more

Chromogenic detection; Gastric cancer; Helicobacter pylori; Stomach cancer; Susceptibility gene; TNF-α

TNF 308 gene polymorphism and IL-10 polymorphism provided evidence in diagnosing some types of cancer. We aimed to explore the relation of gene polymorphism with gastric cancer. A total of 360 cases of gastric cancer patients were included in the study. The genotypes GG, GA, and AA of the interleukin-10-1082 gene (IL-10-1082) and the tumor necrosis factor-alpha gene (TNF- ... more

Folate intake; Gastric cancer; Methylenetetrahydrofolate reductase; Polymorphisms

Folic acid and methylenetetrahydrofolate reductase (MTHFR) may both affect the development of human cancer. We conducted a population-based case-control study in a Chinese population to investigate the potential role of folate intake and MTHFR gene polymorphisms in gastric cancer, and their interaction with infection by Helicobacter pylori and tumor location. A total of ... 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
