Endothelial nitric oxide synthase; Essential hypertension; Meta-analysis; Polymorphism

We examined the effect of polymorphisms in the endothelial nitric oxide synthase gene on the risk for essential hypertension in a Han Chinese population through a meta-analysis of data from 15 studies. Associations between increased risk for essential hypertension and 4b/a were obtained in a dominant model and allele contrast (aa + ab vs bb: odds ratio (OR)FE = 1.26, ... more

CDKAL1; Meta-analysis; Single nucleotide polymorphism; Type 2 diabetes

CDKAL1 (cyckin-dependent kinase 5 regulatory subunit-associated protein 1-like 1) has been shown to be associated with type 2 diabetes in various ethnic groups; however, contradictory results have been reported. We performed a comprehensive meta-analysis of 21 studies for rs7756992, 17 studies for rs7754840 and 10 studies for rs10946398 variants of the CDKAL1 gene to ... more

Cerebrovascular disease; Meta-analysis; Methylenetetrahydrofolate reductase; Polymorphism; Stroke

Several independent studies have reported the role of the methylenetetrahydrofolate reductase gene (MTHFR) A1298C polymorphism in strokes, but the results are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed in the present study. In this meta-analysis, a total of 13 studies, including 1974 cases and 2660 controls, were selected ... more

CCND1 gene; Esophageal cancer; Genetic association; Meta-analysis; Polymorphism

The association between the Cyclin D1 gene (CCND1) G870A polymorphism and esophageal cancer has been widely evaluated, with conflicting results. As meta-analysis is a reliable approach to resolving discrepancies, we aimed to evaluate this association. Data were available from 9 study populations incorporating 1898 cases and 3046 controls. Overall, the allelic/genotypic ... more

Asian; Caspase 8; Genetic polymorphisms; Meta-analysis; Neoplasm

Genetic variation in the CASP-8 gene reportedly can increase cancer susceptibility by regulating tumor cell proliferation and apoptosis. Several studies have investigated this possibility; however, the conclusions remain controversial. We made a Human Genome Epidemiology (HuGE) review and did a meta-analysis to explore the association between CASP-8 gene polymorphisms and cancer risk in ... more

CTLA-4 gene; Diabetes; Meta-analysis; SNPs

The aim of this study was to evaluate the association between the rs3087243 polymorphism of the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) gene and the risk of type 1 diabetes mellitus (T1D). A comprehensive meta-analysis of case-control studies was conducted to determine the association between the rs3087243 polymorphism (CT60A/G) and T1D and assess the joint evidence ... more

COMT; Endometrial cancer; Meta-analysis; Polymorphism

Catechol-O-methyltransferase (COMT) is a critical enzyme to detoxify the carcinogenic catechol estrogen and the Val158Met polymorphism of COMT could influence its enzymatic activity. Recent epidemiological studies have investigated the correlation of COMT Val158Met polymorphism with endometrial cancer risk; however, the results are inconsistent. To better evaluate the role of ... more

Bronchopulmonary dysplasia; Meta-analysis; MicroRNA; Profiling

Over the past several years, several microRNA (miRNA) expression profiling studies have been carried out on bronchopulmonary dysplasia (BPD) in mammalian lung tissues. The most effective way to identify these important miRNAs is to systematically search for similar signatures identified in multiple independent studies. Accordingly, a meta-analysis was conducted to review published miRNA ... more

Chronic obstructive pulmonary disease; Meta-analysis; Polymorphism; Tumor necrosis factor-alpha

Chronic obstructive pulmonary disease (COPD) is a chronic systemic inflammatory disease; increasing evidence indicates that the TNF-α polymorphism is associated with progression of this disease. Few studies have focused upon association between TNF-α -238G/A or -863C/A polymorphism and COPD risk. Reported associations have been controversial because of small sample size and varied study ... more

External apical root resorption; Interleukin-1β; Meta-analysis; Orthodontic; Polymorphism

The purpose of this meta-analysis was to determine whether genetic variants of the interleukin-1β[+3954 C>T (rs1143634)] (IL-1β +3954 C>T) gene polymorphisms were associated with orthodontic external apical root resorption (EARR). A meta-analysis was carried out using data entered into the PubMed and Embase electronic databases before October 5, 2012. A total of 7 studies were ... more
