CYP; GST; p53; Polymorphism; susceptibility; Thyroid disease

Specific genotypes appear to be related to the development of thyroid disease. We examined whether polymorphisms of the genes CYP1A1, GSTM1, GSTT1, and TP53 at codon 72 are associated with increased risk for thyroid nodules. Blood samples were obtained from 122 thyroid patients with nodules and from 134 healthy control individuals from Goiânia city, GO ... more

Hepatocellular carcinoma; miR-146aG>C rs2910164; miR-499A>G rs3746444; susceptibility

We conducted a case-control study of a possible association of miR-499A>G rs3746444 and miR-146aG>C rs2910164 with risk of hepatocellular carcinoma. Samples from 172 hepatocellular carcinoma patients and 185 cancer-free controls were collected from October 2008 to December 2011. PCR-RFLP analysis was performed to determine the polymorphisms in each individual. The MAFs of miR-146aG ... more

Association analysis; Genetic polymorphisms; susceptibility; Toll-like receptor 4; Type 2 diabetes mellitus

Toll-like receptor 4 (TLR4) is potentially an important gene affecting the susceptibility to type 2 diabetes mellitus (T2DM). The objective of this study was to evaluate whether genetic polymorphisms of the TLR4 gene are associated with T2DM susceptibility. This potential association was analyzed in 668 T2DM patients and 672 healthy controls by polymerase chain reaction- ... more

Breast cancer; DNMT; Single nucleotide polymorphism; susceptibility

Patterns of DNA methylation are established and maintained by a family of DNA methyltransferases (DNMTs). Aberrant promoter DNA methylation of tumor suppressor genes is found in breast cancer. Association studies between DNMT gene polymorphisms and breast cancer in various populations have reported inconsistent results. This study assessed the associations of single nucleotide ... more

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

Association between the XRCC1 Arg399Gln polymorphism and susceptibility to gastric cancer has been investigated; overall, the results have been inconclusive. We made a meta-analysis of 13 case-control studies, including 3278 cases and 6243 controls. Crude odds ratios (OR) with 95% confidence intervals (95%CI) were used to assess this possible association. We found no evidence of a ... more

Keloid; Meta-analysis; p53 codon 72 polymorphism; susceptibility

Although there is evidence suggesting genetic susceptibility for keloids, studies investigating the association between Arg72Pro polymorphism in the P53 gene and tendency to form keloids have given variable results. We made a meta-analysis of the effects of P53 Arg72Pro polymorphism on keloid risk in the Chinese population by conducting searches of the published literature in ... more

Killer cell immunoglobulin-like receptor; Polymorphism; Pulmonary tuberculosis; susceptibility

Killer cell immunoglobulin-like receptors (KIRs) are involved in the pathogenesis of a variety of diseases. However, whether KIR polymorphism is associated with susceptibility to pulmonary tuberculosis was unknown. We examined a possible association of KIR polymorphism with susceptibility to pulmonary tuberculosis in Chinese Han. We analyzed 15 KIR genes in 109 pulmonary tuberculosis ... more

17q21; Asthma; Genetic variants; susceptibility

A genome-wide study has shown an association between SNPs located on 17q21 and asthma. Such associations have been identified in several populations, but little is known about the Han Chinese population. We conducted a case-control study in a Han Chinese population to investigate the relationship between SNPs located on 17q21 and asthma; 241 asthmatic patients and 212 healthy controls ... 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

Genetic polymorphisms; Hepatocellular carcinoma; MDR1 gene; Risk factors; susceptibility

The objective of this study was to evaluate the influence of c.1564A>T genetic polymorphisms in the multidrug resistance 1 gene (MDR1) on hepatocellular carcinoma (HCC) susceptibility through association analysis. A total of 632 HCC patients and 645 cancer-free controls were enrolled in this study. The c.1564A>T genetic polymorphisms were genotyped by created restriction ... more
