Gastric cancer; hOGG1 gene; Meta-analysis; Polymorphism; Risk association study

The association between the human 8-oxoguanine glycosylase 1 (hOGG1) gene Ser326Cys polymorphism (rs1052133) and gastric cancer has been widely evaluated, yet a definitive answer to whether this association exists is lacking. We first conducted a case-control study to assess this association in a large Han Chinese population, and then performed a meta-analysis to further address ... more

Meta-analysis; Polymorphism; Psoriasis; Vascular endothelial growth factor

The aim of this study was to explore whether vascular endothelial growth factor (VEGF) polymorphisms confer susceptibil­ity to psoriasis. Meta-analyses were conducted to examine the asso­ciations between the +405 C/G, -460 C/T, -1154 A/G, and -2578 A/C polymorphisms of VEGF and psoriasis using allele contrast and reces­sive, dominant, and additive models. Seven studies ... more

Cancer; Meta-analysis; Polymorphism; Vascular endothelial growth factor

The association between vascular endothelial growth factor (VEGF) gene polymorphisms and risk of cancer has been investigated in several studies published previously; however, the individual results are inconclusive. Therefore, we performed a meta-analysis to establish evidence for an association between the VEGF -634 G/C polymorphism and risk of cancer. We searched ... more

A-20C; Angiotensinogen gene; Essential hypertension; Meta-analysis; Polymorphism

The A-20C polymorphism in the angiotensinogen (AGT) gene has been associated with increased risk of essential hypertension in several studies; however, these studies gave inconsistent results. In this study, we performed a meta-analysis to assess the association between AGT A-20C polymorphism and essential hypertension. Published literature was retrieved from PubMed. ... more

APOA5 -1131T/C; Coronary artery disease; Meta-analysis; Polymorphism

Although many studies have investigated the association of the APOA5 -1131T/C polymorphism with coronary artery disease (CAD), definite conclusions have not been drawn. To understand the effects of the APOA5 -1131T/C polymorphism on the risk of developing CAD, we performed an updated meta-analysis in the Chinese population. Relevant studies published till April 2015 were identified from ... more

CCDC26; Glioma; Meta-analysis; Polymorphism; rs4295627

The association between the CCDC26 rs4295627 single nucleotide polymorphism (SNP) and the glioma risk has been studied previously, but these studies have yielded conflicting results. The aim of the present study is to analyze this association more vigorously, by means of a meta-analysis. A comprehensive literature search was performed in databases PubMed and EMBASE. Six articles ... more

IL-8; Meta-analysis; Periodontitis; Polymorphism

The -251A/T polymorphism in the anti-inflammatory cytokine interleukin-8 (IL-8) gene has been implicated in susceptibility to periodontitis; however, this correlation has not been elucidated. In this meta-analysis, we investigated the association between the IL-8 -251A/T polymorphism and the risk of periodontitis. All eligible case-control studies ... more

GSTM1; GSTT1; Male infertility; Xenobiotics

Male infertility is a heterogeneous disorder, with vari­ous genetic and environmental factors that contribute to the impairment of spermatogenesis. Genetic causes are responsible for 60% of cases of idiopathic infertility. Polymorphisms of genes that encode detoxi­fying enzymes of phase II drug metabolism can modify their expres­sion or function, affecting the biotransformation of toxic ... more

ACE gene; GSTM1; GSTT1; Polymorphism; Retinopathy of prematurity

One of the most frequently observed causes of blindness in infancy is the pathogenesis known as retinopathy of prematurity (ROP). Angiotensin-converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system; it is involved in the development of cardiovascular system diseases linked to I/D polymorphism of the ACE gene. Glutathione-S-transferase enzyme (GST) is one of ... more

Endometriosis; GSTM1; GSTT1; Infertility

Endometriosis is a gynecologic pathology with a high prevalence and unknown etiology. Therefore, an increasing number of studies has been undertaken to search for associations between endometriosis and alterations or polymorphisms in candidate genes, including glutathione S-transferase mu 1 (GSTM1) and glutathione S-transferase theta 1 (GSTT1). We analyzed the frequency of ... more
