A total of 125 Russian Red Pied cows were genotyped for the prolactim-related gene. The PRL-RsaI genotypes were analysed using the Polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP) method. In this breed, the frequencies of alleles were as follows;  A= 0.794 and B= 0.206. The frequencies of AA, AB and BB genotypes were 0.598, 0.392 and 0.01; respectively. Results sho...

The present study aimed to investigate whether the polymorphisms in the TSLPR gene are associated with atopic and asthmatic disease in the Korean population. We identified eleven single nucleotide polymorphisms (SNPs) and two variation sites in the TSLPR gene, including the promoter region. The genotype and allele frequencies of g.33G>C of the TSLPR gene in asthma patients were significantly di...

The objective of this study was to determine the polymorphism of bovine β-lactoglobulin (β-LG) gene and its association with milk production traits in Iranian Najdi cattle. Blood samples were collected from 80 Najdi cattle from the Najdi cattle breeding station located in Shoshtar, Khuzestan. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniqus were used...

Chemokines are potent proinflammatory cytokines that are implicated in numerous inflammatory diseases. Proinflammatory gene polymorphisms lead to variations in the production and concentration of inflammatory proteins. We investigated a possible association between polymorphisms in chemokine and chemokine receptor genes (MCP-1 A-2518G and CCR2-V64I) and bladder cancer risk. Genotypes were deter...

Osteoporosis is a metabolic bone disease affecting mostly elderly women. As metabolizing enzymes, the roles of few cytochromes have been studied in osteoporosis development. The aim of this study was to assess for the first time the association of CYP2E1 and CYP1A1 polymorphisms and osteoporosis in postmenopausal women. 112 postmenopausal women presenting osteoporosis and 93 age and sex matched...

Polymorphism of the b-lactoglobulin (b-LG) gene in 101 cows belonging to the Holstein herd and a superior cow, producing more than 150 Kg milk/day, together with four offsprings was investigated by the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method. In the Holstein herd, the alleles A and B of the b-LG gene had frequencies of 0.53 and 0.47, respectively. Th...

henoch–schönlein purpura (hsp), a common allergic hemorrhagic disease, occurs frequently in children affecting kidney, joint and skin. while interleukin-8 (il-8) plays an important role in inflammation, the association between il-8 gene +781 c/t polymorphism and hsp remains unclear. interleukin-8, an important chemokine related to the initiation and amplification of acute inflammatory responses...

this study was conducted to investigate the single nucleotide polymorphism of stat1 gene by pcr-rflp technique and association of genotypes with milk production traits in brown swiss dairy cattle. the blood samples of ninety eight cows were collected randomly from tail vein. the dna was extracted with cinagene kit (pr881612c). fragment of 314 bp of stat1 gene was amplified by pcr and digested b...

The use of polymorphic markers in breeding programmes could make selection more accurate and efficient. A total of 324 individuals from six Iranian cattle populations (Sarabi, Golpayegani, Sistani, Taleshi, Mazandarani, Dashtiyari), F1 Golpayegani × Brown Swiss and Iranian buffalo populations were genotypedfor the Pit-1 HinfI and leptin Sau3AI polymorphisms by the polymerase chain reactio...
