Gastric cancer; Meta-analysis; NQO1 gene; Polymorphism; Risk

The association between the NAD(P)H: quinone oxidoreductase 1 (NQO1) gene C609T polymorphism and gastric cancer has been widely evaluated, yet with conflicting results. Data were available from seven study populations involving 2600 subjects. Overall, comparison of alleles 609T and 609C indicated a significantly increased risk (46%) for gastric cancer (95% confidence interval (95 ... more

Genetic polymorphisms; Meta-analysis; Prostate cancer; PTGS2

Evidence is accumulating that chronic inflammation has an important role in prostate cancer. Two common polymorphisms in the prostaglandin-endoperoxide synthase 2 (PTGS2) gene, rs20417 and rs689470, have been found to alter the risk for prostate cancer, but the various studies are not in agreement. To derive a more precise estimation of this association, all available studies were ... more

Dopamine D2 receptor; Gene polymorphism; Meta-analysis; Schizophrenia

Numerous studies have evaluated the association between Ser311Cys (rs1801028, C>G) polymorphism of the dopamine D2 receptor (DRD2) gene and schizophrenia risk. However, the specific association is still controversial. We examined whether DRD2 Ser311Cys polymorphism confers schizophrenia risk in Asian populations. Sixteen studies were retrieved reporting on a total of 2268 schizophrenia ... more

Alzheimer’s disease; Meta-analysis; MicroRNA; Oxidized low density lipoprotein receptor 1; Polymorphism

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that contributes to dementia in the elderly population. Genome-wide linkage analysis has identified chromosome 12p as the AD-susceptible region, which includes lectin-like oxidized low-density lipoprotein receptor 1 (OLR1). The OLR1 +1073 C/T single-nucleotide polymorphism is located in the 3'- ... more

Meta-analysis; Microsomal transfer protein; Non-alcoholic fatty liver disease; Polymorphism

Several studies have found that microsomal transfer protein (MTP) may be important in the development and progression of non-alcoholic fatty liver disease (NAFLD). In this meta-analysis, we evaluated the relationships between a common polymorphism (-493G>T, rs1800591 G>T) in the MTP gene and NAFLD risk. The PubMed, CISCOM, CINAHL, Web of Science, Google Scholar, EBSCO, ... more

Gastric cancer; Meta-analysis; Prognosis; S100A4

The prognostic role of S100A4 in gastric cancer is still under debate. The present meta-analysis aimed to evaluate the relationship between S10A4 levels and the prognosis of gastric cancer. We performed a meta-analysis of published studies assessing the relationship between S100A4 and gastric cancer prognosis. We used the Revman 5.0 software to perform literature retrieval, article ... more

Genetic polymorphism; Hypodontia; Meta-analysis; PAX9

To evaluate the association between paired box 9 (PAX9) gene polymorphisms and tooth agenesis in isolated humans, we performed a comprehensive meta-analysis. We examined 6 case-control studies, with a total of 855 hypodontia cases and 1201 healthy controls. The G allele and G carrier (AG + GG) of A1031G were positively associated with hypodontia susceptibility. Similarly, the T ... more

Cardiovascular disease; Meta-analysis; Myocardial infarction; Visfatin

Visfatin, an adipocytokine involved in metabolic and immune disorders, plays an important role in the etiology of cardiovascular disease. Recent evidence has shown that an elevated plasma level of visfatin may increase the risk of myocardial infarction (MI), but individual published studies have shown inconclusive results. This study aimed to obtain a more precise estimate of the ... more

Atrial fibrillation; KCNE1; Meta-analysis; Polymorphism; susceptibility

KCNE1, a membrane protein that spans the membrane once is responsible for modulating potassium channel functions and plays an important role in the etiology of arrhythmia. Emerging evidence indicates that a common polymorphism (112G>A; rs1805127 G>A) in the KCNE1 gene contributes to atrial fibrillation (AF) risk; however, these studies showed inconclusive results. In this ... more

Angiotensin-converting enzyme; Association; Meta-analysis; Polymorphism; Systemic sclerosis

The purpose of this study was to examine whether the insertion (I) or deletion (D) polymorphism of the angiotensin-converting enzyme gene (ACE) is associated with susceptibility to systemic sclerosis (SSc). A meta-analysis examining the associations between the ACE I/D polymorphism and SSc was conducted in overall and European populations using 1) allelic contrast (D ... more
