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

Breast cancer; Chinese Han population; MHC class-III; Single nucleotide polymorphism

Polymorphisms of the major histocompatibility complex (MHC) have been linked to many diseases, especially autoimmune disorders. Previous studies have shown that genetic variants in MHC class III are associated with breast cancer. To determine if there is an association between MHC class III and breast cancer risk in the Chinese Han population, we carried out a hospital-based case-control ... more

Haplotype; Male infertility; Single nucleotide polymorphism; UBE2B

The ubiquitin-conjugating enzyme 2B gene (UBE2B) is involved in the regular and symmetric organization of the fibrous sheath of sperm flagella. This study aimed to examine the relationship between single nucleotide polymorphisms (SNPs) in UBE2B and infertility in Northeast Chinese men. We carried out a polymerase chain reaction-restriction fragment length polymorphism ... more

Breeding value; Candidate gene; Chicken; Economic trait; Single nucleotide polymorphism

Neuropeptide Y (NPY) and gonadotrophin-releasing hormone receptor (GnRHR) are two candidate genes with a wide variety of physiological functions in growth and especially in reproduction processes. We examined the association of one SNP from each of these genes with growth- and egg production-related traits in Mazandaran native chickens. Two hundred and six individuals were genotyped by ... more

Mutation; NOD; SH2B3; Single nucleotide polymorphism

Type 1 diabetes is a chronic progressive autoimmune disease characterized by mononuclear cell infiltration, with subsequent destruction of insulin-producing β-cells. Studies have identified strong associations between type 1 diabetes and several chromosome regions, including 12q24. Association between type 1 diabetes and 12q24 arises from SNP rs3184504; rs3184504 is a nonsynonymous SNP in ... more

Crohn’s disease; IRGM; Meta-analysis; Single nucleotide polymorphism

This meta-analysis was performed to evaluate the relationships between single-nucleotide polymorphisms (SNPs) in the immunity-related GTPase M (IRGM) gene and the risk of Crohn’s disease (CD). Eleven case-control studies were included, for a total of 5183 CD patients and 5571 healthy controls. Three common SNPs (rs13361189 C>T, rs10065172 C>T, and rs4958847 A>G) in the ... more

Body measurement; Genetic variability; meat quality; Single nucleotide polymorphism; SIRT2

Silent information regulator 2 (SIRT2), a member of the Sirtuin family of class III nicotinamide adenine dinucleotide-dependent protein deacetylases, plays an important role in senescence, metabolism, and apoptosis. This study was conducted to detect potential polymorphisms of the bovine SIRT2 gene and explore their relationships with meat quality and body measurement traits ( ... more

Chemotherapy; Excision repair cross-complementation group 1; Non-small cell lung cancer; Single nucleotide polymorphism; Survival time

We conducted a cohort study to investigate the role of 3 single-nucleotide polymorphisms of the excision repair cross-complementation group 1 (ERCC1) gene on the response to chemotherapy and clinical outcomes of non-small cell lung cancer (NSCLC). A total of 163 patients with newly diagnosed and histopathologically confirmed primary NSCLC were examined in our study and were ... more

Capra hircus; Cytokine; Gastrointestinal infection; Single nucleotide polymorphism

Cytokines are small cell-signaling proteins that play an important role in the immune system, participating in intracellular communication. Four candidate genes of the cytokine family (IL2, IL4, IL13, and IFNG) were selected to identify Single Nucleotide Polymorphisms (SNPs) that might be associated with resistance to gastrointestinal endoparasites in ... more

Case-control study; DKK1; Single nucleotide polymorphism; Tooth agenesis

Tooth agenesis is one of the most common anomalies of human dentition. Recent genetic studies have provided information regarding a number of genes related to both syndromic and non-syndromic forms of hypodontia. In a previous study, we found that polymorphism in rs11001553 of DKK1 was associated with hypodontia in the Chinese Han population. In this study, we extended this ... more
