Goat; Growth traits; Myostatin gene (MSTN); PCR-SSCP; Polymorphism

Mutations in the myostatin (MSTN) gene can inactivate its expression and result in a non-functional protein, which leads to dramatic muscularity and a “double-muscling” phenomenon in many species. Using gene sequencing and polymerase chain reaction-single-strand conformation polymorphism methods, polymorphisms of the MSTN gene were investigated as a candidate marker for ... more

Cattle; Hanwoo; Phospholipid transfer protein; Polymorphism; SNP

Phospholipid transfer protein (PLTP) regulates high-density lipoprotein metabolism. The gene encoding PLTP is located on bovine chromosome 13. The objective of this study was to identify single nucleotide polymorphisms (SNPs) in the Hanwoo (Bos taurus coreanae) PLTP gene to detect novel mutations affecting economically important traits. Five SNPs were identified in the coding ... more

IL-18; Polymorphism; Prostate cancer

Interleukin-18 (IL-18) has been implicated in a wide variety of cellular functions that affect the biological response to tumors. However, there is insufficient evidence to prove that IL-18 gene variants are associated with risk of prostate cancer. We examined a possible association between two promoter polymorphisms, -137G/C (rs187238) and -607C/A (rs1946518), in the IL-18 ... more

Chicken; Cloning; Expression; Nramp1 gene; Nramp2 gene; Polymorphism

Natural resistance-associated macrophage protein 1 and 2 encoding genes (Nramp1 and Nramp2) are related to many diseases. We cloned the cDNA of chicken Nramp1 and Nramp2 genes, characterized their expression and polymorphisms, and investigated the association of some SNPs with resistance to salmonellosis. The Nramp1 cDNA was 1746 bp long and the ... more

The fungus Mycosphaerella fijiensis is the causative agent of black sigatoka, which is one of the most destructive diseases of banana plants. Infection with this pathogen results in underdeveloped fruit, with no commercial value. We analyzed the distribution of the M. fijiensis mating-type system and its genetic variability using M13 phage DNA markers. We found a 1:1 ... more

P2X7; Polymorphism; Tuberculosis

Susceptibility to tuberculosis may be influenced by variations in human genes. The P2X7 receptor is an ATP-gated cation channel expressed in immune cells, and it influences the release of proinflammatory cytokines from monocytes and macrophages. In the present study, we aimed to evaluate the impact of P2X7 gene rs2393799 (-762T/C) and rs1718119 (Thr348Ala) polymorphisms ... more

Polymorphism; Rheumatoid arthritis; Toll-like receptor

We investigated whether Toll-like receptor (TLR) polymorphisms confer susceptibility to rheumatoid arthritis and whether they influence clinical characteristics of rheumatoid arthritis. Studies were considered relevant for our meta-analysis if at least two comparisons of an issue were available. Eleven studies with 2078 patients with rheumatoid arthritis and 2581 controls were ... more

Early growth traits; Hu sheep; MC4R gene; Polymorphism

The melanocortin-4 receptor (MC4R) has important roles in regulating food intake, energy balance, and body weight in mammals. In pigs and cattle, MC4R mutations have been identified as genetic markers for growth and traits. Compared with abundant research conducted on other livestock species, little is known about mutations of the ovine MC4R gene. We investigated the ... 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

Bladder cancer; Genetic susceptibility; hOGG1; Meta-analysis; Polymorphism

The functional polymorphism Ser326Cys (rs1052133) in the human 8-oxoguanine DNA glycosylase (hOGG1) gene has been implicated in bladder cancer risk. However, reports of this association between the Ser326Cys polymorphism and bladder cancer risk are conflicting. In order to help clarify this relationship, we made a meta-analysis of seven case-control studies, summing 2521 cases ... more
