Lactoferrin (Lf) is a bioactive protein present in all external secretions such as milk that plays important role in the innate host defense. Therefore, the Lf has a major role in bovine mammary gland defense during mastitis. In this study, 5’-flanking region of bovine Lf gene containing three single nucleotide polymorphisms (SNPs) at positions −602 (T/G), −600 (A/G) ...

We have carried out a structural and functional analysis on the human NF-L (H-NF-L) gene. It contains a methylation-free island, spanning the 5' flanking sequences and the first exon and a number of neuronal-specific DNase I hypersensitive sites have been identified in the upstream region as well as within the body of the gene. Analysis in cell lines and transgenic mice using a combination of t...

The rat class 3 aldehyde dehydrogenase gene (ALDH3A1) is expressed constitutively or by xenobiotic induction depending on the tissue in which it occurs. Although the mechanism that mediates inducible expression has been well characterized, relatively little is known about constitutive regulatory mechanisms. Previous ALDH3A1 promoter analyses have indicated that primary regulatory regions within...

The neutral theory of molecular evolution predicts that regions of the genome that evolve at high rates, as revealed by interspecific DNA sequence comparisons, will also exhibit high levels of polymorphism within species. We present here a conservative statistical test of this prediction based on a constant-rate neutral model. The test requires data from an interspecific comparison of at least ...

The whey acidic protein (WAP) is the major whey protein in rodent and rabbit milk. Its cDNA sequence has been described in the mouse (1), the rat (1), and the rabbit (2). The mouse and rat gene sequences have already been published (3), as well as part of the 5' flanking region of the rabbit WAP gene (4). The entire sequence of the rabbit WAP gene with 1821 bp of the 5'P flanking region and 612...

We have set up an experimental system to map the primary transcription unit of the human alpha 2 globin gene. The duplicated human alpha globin genes (alpha 2-alpha 1) were linked to the alpha globin locus Positive Regulatory Element (PRE) and stably transfected into murine erythroleukaemia cells. We then developed a quantitative reverse transcriptase, polymerase chain reaction assay to map alp...

The growth hormone receptor (GHR) is a member of cytokine/hematopoietin family that mediates the biological actions of growth hormone (GH) on target tissues. Therefore, the purpose of this study was to examine the association of TG-repeat polymorphisms in the 5’-flanking region of bovine GHR gene with milk production traits and somatic cell score (SCS) in Holstein cattle of Iran. The part of 5’...
