Lactoferrin is a glycoprotein with molecular weight 80 kDa iron-binding bond, which is composed of 690 amino acids. In most mammalian body fluids such as sweat, semen, tears, and saliva and milk neutrophil granules there. bovine lactoferrin gene be associated with susceptibility/resistance to mastitis and even with some economically important production traits. This study was carried out to det...

Understanding patterns of gene-expression variation within and among human populations will provide important insights into the molecular basis of phenotypic diversity and the interpretation of patterns of expression variation in disease. However, little is known about how gene-expression variation is apportioned within and among human populations. Here, we characterize patterns of natural gene...

background: campylobacter jejuni and campylobacter coli are zoonotic bacteria which are frequently associated with human diarrhea. sharing of the cytolethal distending toxin (cdt) genes in campylobacter is common and is considered species specific. objectives: in this study we focused on detecting the presence of cdt gene in c. jejuni and c. coli isolated from broilers, turkeys and quails of ir...

Background Genetic variation can cause changes in gene expression (mRNA abundance) among individuals. This so-called heritable variation in gene expression is affected by genetic variants that are co-segregating with the gene locus (local/cis effects) and/or segregating independently from it (distant/trans effects). Genetic variation in gene expression can be measured to estimate the extant of ...

objective: since the identification of the two highly penetrant dominantly inherited genes, brca1/2, in the 1990s, a number of other genes have been identified which account for approximately 25% of the genetic basis for hereditary breast cancer. at least 75% are unidentified. the goal of this study is to investigate the presence or absence of a recessive pattern of inheritance in this heteroge...

the aim of this study was to investigate the possible influence of interferon-gamma (ifn- γ) gene polymorphism +874 (a/t) (rs2430561) in the susceptibility and renal complications of patients with henoch-schonlein purpura (hsp). we also studied the effects of ifn-γ allelic variation on serum levels of pro-and anti-inflammatory cytokines in hsp patients. the  study  population  comprised  97  pa...

molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in livestock. the insulin like growth factor-i (igf-i) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. the objectives of the present study were the estimate the haplotype frequencies of the igf-i gene polymorphisms i...
