Growing evidence suggests that RAD51 plays a pivotal role in the repair of DNA double-strand breaks and the maintenance of genomic stability. A single nucleotide polymorphism, 135G/C, has been identified in the 5′ untranslated region of the RAD51 gene and has been shown to influence gene transcription activity. Previous studies yielded conflicting results(More)
BACKGROUND AND OBJECTIVES Glutathione S-transferases (GSTs) are multifunctional enzymes that play a key role in the detoxification of varieties of both endogenous products of oxidative stress and exogenous carcinogens. METHODS In this meta-analysis, twenty-five studies were identified by searching PubMed, EMBASE, ISI Web of Science and CBM databases: 23(More)
BACKGROUND Emerging evidence suggests that ataxia telangiectasia-mutated (ATM) is involved in numerous damage repair signaling pathways and cell-cycle checkpoints. Heterozygous carriers of ATM-mutations have an increased risk for the development of breast cancer. The purpose of this study is to evaluate the association between ATM exon39 5557G > A (D1853N,(More)
X-chromosomal short tandem repeats (ChrX STRs) loci are used for forensic practice in recent years. Considering the unique heredity characteristics of ChrX, recombination and linkage disequilibrium (LD) among ChrX STR loci vary between male and female and different populations as well. However, there is a lack of data for analysis of recombination and(More)
Matrix metalloproteinases (MMPs) play an important role in colorectal cancer (CRC). Accumulated evidence suggests an association between MMP-1, MMP-7, and MMP-9 functional gene polymorphisms with several tumors. The aim of this study was to investigate the association of single-nucleotide polymorphism (SNP) at MMP-1 16071G/2G, MMP-7 181A/G, and MMP-9 279R/Q(More)
Interleukin (IL)-16, a multifunctional cytokine, plays a fundamental role in inflammatory diseases, as well as in the development and progression of tumors. Genetic variation in the DNA sequence of the IL-16 gene may lead to altered cytokine production and/or activity, and this variation may modulate an individual's susceptibility to both colorectal cancer(More)
Single-nucleotide polymorphisms (SNPs) in pre-miRNAs may alter microRNA (miRNA) expression levels or processing and contribute to susceptibility to a wide range of diseases. We investigated the correlation between four SNPs (rs11614913, rs3746444, rs2910164, and rs229283) in pre-miRNAs and the risk of asthma in 220 asthma patients and 540 controls using(More)
Growing evidence suggests that interleukin-8 (IL-8) play pivotal roles in the pathogenesis of cancer through the modulation of tumour immune response or enhanced angiogenesis. A single nucleotide polymorphism, -251A/T, has been identified in the promoter region of the IL-8 gene and has been shown to influence its production. Results from previous studies on(More)
Chronic obstructive pulmonary disease (COPD) may be related to chronic inflammation and immune-mediated conditions, and its pathogenesis involves T-cell activation and proliferation. Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and costimulatory molecules (CD80/CD86) genes are important mediators of T-cell activation in the immune response. The aim(More)
Numerous candidate genes have been proposed as susceptibility factors for the development of nasopharyngeal carcinoma (NPC). Epidermal growth factor (EGF) and epidermal growth factor receptor (EGFR) interaction plays a pivotal role in cell proliferation, differentiation, and tumourigenesis of epithelial tissues. To our knowledge, however, no study has(More)
