Association; Cattle; Genotypic frequencies; meat quality; Mutation; Myogenic factor 5

Qualitative trait loci (QTL) for growth and meat quality traits in cattle (Bos taurus) have been previously mapped to three chromosome regions, 0 to 30, 55 to 70, and 70 to 80 cM on chromosome 5. We evaluated the allele frequencies and gene-specific single nucleotide polymorphisms (SNPs) of bovine myogenic factor 5 (MyF-5) in the QTL regions and their associations with live ... more

Calcium; Chicken; meat quality; Mutation; Porcine stress syndrome; Ryanodine receptor

The development of pale, soft, and exudative (PSE) breast fillet meat has become an economic burden for the poultry industry worldwide. PSE meat results in 1.0-1.5% loss in moisture and carcass weight, and a 2010 estimate of the Brazilian annual production put the economic loss due to PSE at over US$30 million. In the USA, PSE has caused an annual loss of up to US$200 million to the ... more

Allelic frequencies; meat quality; Myogenic determination gene 1; Qinchuan cattle; Single nucleotide polymorphism

The myogenic determination 1 (MyoD1) gene is a member of the MyoD gene family. It encodes for skeletal muscle-specific transcription factors containing highly conserved basic helix-loop-helix regions that perform important roles in the initiation, maintenance, and regulation of phenotypic traits. We investigated a new single nucleotide polymorphism (SNP) in the MyoD1 gene to evaluate ... more

Adipocyte fatty acid-binding protein; Gene expression; Longissimus dorsi; meat quality; Pigs; Polymorphism

Recent attention in pig breeding programs has focused on the improvement of pork quality in response to increasing consumer demands. Compared to the fatty-type Northeastern Indigenous (Chinese) breed of pigs, the lean-type Large White has lower intramuscular fat and inferior eating quality from the perspective of the Chinese consumer. In order to investigate the molecular basis of ... more

Ammonia; Antioxidative capacity; broiler; meat quality; Relative humidity

To investigate the effect of humidity and ammonia on the antioxidative capacities and meat qualities of broilers, 192 broilers were divided into 2 groups: high (H, 70 ppm) and low (L, 30 ppm) ammonia concentration. These groups were divided into 30% (Treatment humidity, T) and 60% (Control humidity, C) humidity, giving 4 treatments: C+L, C+H, T+L, and T+H. Blood and muscle antioxidative ... more

Gliomas; Mutation; PAX6

Gliomas are the most common tumors of the central nervous system. In spite of the marked advances in the characterization of the molecular pathogenesis of gliomas, these tumors remain incurable and, in most of the cases, resistant to treatments, due to their molecular heterogeneity. Gene PAX6, which encodes a transcription factor that plays an important role in the development ... more

Glucokinase; Jordanian; MODY2; Mutation

Maturity-onset diabetes of the young type 2 (MODY2) is a genetic form of diabetes mellitus caused by mutations in the glucokinase gene (GCK). We assessed the frequency of GCK gene mutations in Jordanian suspected MODY2 patients. We screened exons 7, 8 and 9, which are specific for pancreatic glucokinase, for mutations at positions 682A>G, p.T228A; 895G>C, p.G299R, and ... more

Anencephaly; Birth defects; Mutation; Neural tube defects; Spina bifida

The incidence of neural tube defects is higher in Turkey compared to that of developed countries. To prevent congenital malformations, understanding of the current status is necessary, which should be followed by public-based activities. We examined the incidence rate of neural tube defects (NTDs) in Afyonkarahisar. According to the records of the Department of Pediatrics, Zubeyde Hanım ... more

Ananas comosus var. bracteatus; Genetic variation; In vitro culture; Mutation; Somaclonal variation

The objective of the present study was to evaluate the genetic variability in micropropagated plantlets of ornamental pineapple, after the fourth period of subculture. The basal culture medium consisted of MS salts, vitamins, 3% sucrose, liquid formulation, supplemented with 6-benzylaminopurine (BAP) at concentrations of 0.125, 0.25, 0.5, 1.0, and 2.0 mg/L. The addition of BAP influenced the ... more

We analyzed distribution of HLA-B27 and CYP2D6*4 mutations in 249 patients from Tokat province in Turkey with symptoms of arthritis, sacroiliac, joint and back pain, using a LightCycler 480 II Real-Time PCR thermal cycler. The Genes-4U was applied for studying HLA-B27 mutation, and the Tib-Molbiol commercial kit was used to examine the CYP2D6*4 mutation. Among the 249 patients, 18.5% had ... more
